Operative treatment of a humeral shaft fracture results in faster recovery than nonoperative treatment. The cost-effectiveness, in terms of costs per Quality-Adjusted Life Year (QALY) gained  or minimal important change (MIC) in disability reduced (DASH 6.7), is unknown. The aim of this study was to determine cost-utility and cost-effectiveness of operative versus nonoperative treatment in adults with a humeral shaft fracture type 12A or 12B.This study was performed alongside a multicenter prospective cohort study. Costs for health care and lost productivity until one year after trauma were calculated. The incremental cost-utility ratio (ICUR) was reported in costs per QALY (based on the EuroQoL-5D-3L (EQ-5D)) gained. The incremental cost-effectiveness ratio (ICER) was reported in costs per MIC (based on the DASH score at three months) reduced.p < 0.001) and QALYs  were higher. The ICUR of operative treatment was €111,860 per QALY gained . The DASH was 7.3 points (p < 0.001) lower in the operative group. The ICER of operative treatment was €2880 per MIC in disability reduced .Overall, 245 patients were treated operatively and 145 nonoperatively. In the operative group, the mean total costs per patient  exceeds the threshold. However, the incremental costs of €2880 per clinically meaningful difference in DASH are much lower and suggest that operative treatment for a humeral shaft fracture is cost-effective.The online version contains supplementary material available at 10.1007/s00068-022-02160-1. In an era of budget restraints on health care costs, efficient resource use is crucial and data on cost-effectiveness of treatment are gaining importance in health care budget allocation –3. In thHumeral shaft fractures pose a burden on society as they make up 3% of all orthopedic injuries . In the Humeral shaft fractures can be managed operatively or nonoperatively, with both treatments resulting in high union rates and excellent results . NonoperThese findings are not yet supported by data on health care consumption and costs . Policy-e.g., polytrauma, open fractures, pathological fractures, bone disorders (excluding osteoporosis), rheumatoid arthritis, or pre-existing impaired upper extremity function). Furthermore, patients with expected problems with follow-up  or insufficient comprehension of the Dutch language were excluded. Full details on inclusion and exclusion criteria are available in the published study protocol [These economic analyses were performed alongside the observational HUMMER study . The stuprotocol .Treatment was left to the treating physician and consisted either of operative treatment with plate osteosynthesis or IMN, or nonoperative treatment with a splint, plaster, collar and cuff, or hanging cast, followed by a Sarmiento brace.The effect measure for the CUA was the Quality-Adjusted Life Years (QALYs). The mean increase in QALYs during one year was calculated using the EuroQol-5D-3L (EQ-5D), a validated questionnaire recommended for assessing quality of life in trauma patients, especially for economic assessments –20. PartThe effect measure for the CEA was the Disabilities of the Arm, Shoulder, and Hand (DASH) score at three months, as at that time, a clinical difference was expected . The DASThese economic analyses were performed from a societal perspective, following Dutch guidelines , 25. DatReference prices of health care resources were derived from the Dutch manual for costing in economic evaluations where possible  . Other rIndirect societal costs due to work absence were calculated using the friction cost method . Costs fU test. For the pairwise comparison of the mean costs, the bootstrap 95% confidence interval (95% CI) was computed based on 1000 replications. Since the time horizon was one year, no discounting was required for costs and health utilities. Results were reported following the CHEERS Checklist for reporting economic health evaluations [p value < 0.05 was taken as a threshold for statistical significance in all statistical tests.Data were analyzed using the Statistical Package for the Social Sciences version 25 . Missing data were not imputed. Data were averaged for patients for whom data were available. Analysis was performed according to intention to treat and all statistical tests were two-sided. Chi-squared analysis was used for statistical testing of categorical data. Functional outcomes that were repeatedly measured over time were compared between treatment groups using linear mixed-effects regression models, as described before . The modluations . A p valThe incremental cost-utility ratio (ICUR), comparing operative versus nonoperative treatment, was expressed in terms of incremental mean total costs per mean QALY gained and calculated by dividing the difference of the mean total costs by the difference of the mean increase in QALYs over 12 months. The Dutch threshold of maximum costs per QALY was used  –15, 35.The incremental cost-effectiveness ratio (ICER), comparing operative treatment versus nonoperative treatment, was reported in terms of incremental costs for a clinically meaningful difference (6.7 DASH points reduced at the three months’ time point). The ICER was calculated by dividing the difference of the mean total costs of the two interventions by the difference of the mean DASH score at three months and multiplied by 6.7. This ratio, with a different time interval used in the numerator and denominator, was chosen in order to compare clinical expected differences to the total costs of treatment, as a difference in DASH score was expected at three months and treatment of a humeral shaft fracture usually does not exceed one year .25–P75 35–66) versus 62 (P25–P75 49–71) years; p < 0.001) and more often male  (Table p = 0.016) and worked more hours per week . Twenty patients were lost to follow-up due to mortality (N = 4) or withdrawal of consent (N = 16). The total number of patients available for follow-up varied per follow-up moment, as 55 patients did not show up at least one follow-up visit.Between October 23, 2012 and October 3, 2018, 390 patients were included of whom 245 (62.8%) were treated operatively and 145 (37.2%) nonoperatively. Compared with the nonoperative group, patients in the operative group were younger (median age of 53 (Pp < 0.001), which was mostly attributable to a faster increase in health-related quality of life in the first six months.The mean increase in QALYs during one year was 0.028 higher after operative treatment (mean of 0.806 (95% CI 0.801–0.811) versus 0.778 (95% CI 0.771–0.784) in the nonoperative group; p = 0.001).There was a significant and clinically meaningful difference in DASH score of 7.3 points between the operative and nonoperative group at three months follow-up, in favor of the operative group (mean of 22.3 (95% CI 19.9–24.6) versus 29.6 (95% CI 26.6–32.6) in the nonoperative group; N = 145, 100%) for a median stay of 2 (P25–P75 2–4) days. In the nonoperative group, 26 (17.9%) patients were admitted for a median stay of 2 (P25–P75 2–3) days. Patients in the operative group had significantly more medical imaging units during their primary stay compared to the nonoperative group (median 4 (P25–P75 2–4) versus 2 (P25–P75 2–2) units; p < 0.001). During follow-up, patients in the nonoperative group had significantly more medical imaging, used more devices for immobilization, and had more outpatient clinic visits. Besides that, compared with the operative group, a doubling of surgical reinterventions was found in the nonoperative group (12.2% (N = 30) versus 25.5% (N = 37); p < 0.001). Reinterventions in the operative group (N = 30) were performed due to implant-related complications (N = 19), nonunion (N = 10), and a deep infection (N = 1). Surgical interventions in the nonoperative group (N = 37) consisted of conversions to osteosynthesis of the humeral shaft fracture due to nonunion (N = 20), malunion (N = 11), pain (N = 5), and persistent radial nerve apraxia (N = 2).An overview of the mean health care consumption and work absenteeism per patient is shown in Table p = 0.253).Although the operative group resumed work seven days earlier (26 versus 33 days in the nonoperative group), there was no significant difference in work absence in days (p < 0.001) (Table p < 0.001). The mean costs of surgery attributed to almost half of the costs of primary stay (€2434). The mean follow-up costs per person were significantly lower in the operative group . The mean costs for ambulance transport, medical imaging (primary stay), initial treatment, and hospital admission days (primary stay) were significantly higher in the operative group. The mean costs of devices for immobilization , medical imaging (follow-up), and mean costs related to revision surgery and consequent hospital admission days were significantly lower in the operative group.An overview of the mean health care costs per patient is shown in Table 1) Table . In addiThe main cost drivers for operative treatment were costs for lost productivity (25%), surgery (20%), hospital admission (primary stay) 15%), and physical therapy (10%) . The mean change in QALYs until 12 months was 0.028 (p < 0.001) higher in the operative group. Hence, this resulted in incremental costs for operative treatment of €111,857  per QALY gained.Operative treatment resulted in higher mean total costs per person until 12 months of €3132  in favor of operative treatment, resulting in incremental costs for operative treatment of €2880  for a meaningful change in disability.The mean difference in DASH score was 7.3 points (p < 0.001) than nonoperative treatment. The mean difference in QALYs  during one year in favor of the operative group demonstrates that operative treatment results in a higher health-related quality of life during the first year after trauma. This difference is statistically significant but small, therefore incremental costs per QALY gained are high . The clinical and statistically significant difference of 7.3 DASH points (p < 0.001) in favor of the operative group exceeds the MIC and results in incremental costs for operative treatment of €2880 for a measurable change in disability.This study showed that operative treatment of a humeral shaft fracture results in higher mean costs per person over one year of €3132 , resulting in marginal differences in QALYs gained [The different measures of efficacy used in these economic analyses should be carefully weighted in the decision-making process. Economic evaluations with QALYs may be preferred in order to allow for comparison across populations with different medical conditions. However, a humeral shaft fracture does not necessarily affect a patient’s self-reported health-related quality of life as the injury may have little effect on some of the measured domains of the EQ-5D  described comparable direct health care costs of upper arm fractures of €4440 per case (versus €5116 in this study), taking into account inflation and the more detailed health care resource use described in this study [ etal. (2013) determined higher direct health care costs  versus €7589) and higher costs for lost productivity (US$4868 (≈ €4023 versus €2894 in this study) per humeral fracture [etal. (2006) described similar total costs of humeral shaft fractures in the Netherlands, namely €9430 per patient, with also hospital care costs and costs for lost productivity as main cost drivers [The results of the cost calculations are comparable with results from previous research. Polinder fracture . Meerdin drivers .etal. (2020) identified no advantage for faster return to work after operative or nonoperative treatment of humeral shaft fractures [Patients’ preferences shape clinical decision-making which therefore could be influenced by employment status. It is desirable that employed patients return to work as soon as possible, especially knowing that costs for lost productivity account for more than a quarter of the total costs of treatment of a humeral shaft fracture and added up to €5.4 million in the Netherlands for admitted patients alone in 2012 . Hendy eractures . This ste.g., differing policies on follow-up procedures and allocation of resources).The strengths of this study include a large multicenter prospective cohort methodology measuring health utility, a formal economic costing approach, and a societal perspective for costs. Furthermore, this study design ensures great external validity by allowing for variation between hospitals . Moreover, costs were based on Dutch prices and practices and therefore may vary depending on the health care system used. Furthermore, the follow-up duration of 12 months did not take into account the late complications of nonunion or the need for revision surgery after more than one year. Lastly, the lack of an upper age limit for age inclusion may have (slightly) skewed the results, based on life expectancy and working situation.This study showed that operative treatment of a humeral shaft fracture is more expensive than nonoperative treatment, but results in a higher health-related quality of life and significantly less disability. Due to the limited effect of a humeral shaft fracture on quality of life measured with the EQ-5D, the cost-effectiveness of operative treatment in terms of costs per QALY  exceeds the acceptability limit. However, the incremental costs of €2880 per clinically meaningful difference in DASH are much lower and suggest that operative treatment for a humeral shaft fracture is cost-effective.Supplementary file1 (DOCX 28 KB)Supplementary file2 (DOCX 21 KB)Below is the link to the electronic supplementary material.


Prostate cancer is the second most common cancer in males worldwide and the third most common among Iran’s male population. However, there is a lack of evidence regarding its direct and indirect costs in low and middle-income countries. This study intends to bridge the gap using a cost of illness approach, assessing the costs of prostate cancer from the perspectives of patients, society, and the insurance system.Two hundred ninety seven patients were included in the study. Data for a 2-month period were obtained from patients registered at two hospitals  in Iran in 2017. We applied a prevalence-based, bottom-up approach to assess the costs of the illness. We used the World Health Organization methods to measure the prevalence and investigate the determinants of catastrophic and impoverishing health expenditures.We determined the total costs of the disease for the patients to be IRR 68 million . Total costs of the disease from the perspective of the society amounted to IRR 700,000 million (PPP $ 54 million). Insurance companies expended IRR 20 million  per patient. Our findings show that 31% of the patients incurred catastrophic health expenditure due to the disease. Five point forty-four percent (5.44%) of the patients were impoverished due to the costs of this cancer.We found an alarmingly high prevalence of catastrophic health expenditures among prostate cancer patients. In addition, prostate cancer puts a substantial burden on both the patients and society.The online version contains supplementary material available at 10.1186/s12962-023-00493-1. Prostate cancer is the second most common cancer in males worldwide. It is estimated that 1.4 million new prostate cancer cases were detected during 2020 . ProstatComplex interrelations between socio-economic and demographic factors are known to cause shifts in disease incidences from communicable to non-communicable diseases , 6. ThisCost of illness studies are prevalent in the literature. In the earlier days, these studies were used for the advocacy purpose of resource allocation for the diseases of interest. More widespread use of these studies has been shown to be beneficial in providing a baseline for future interventions, health benefits packages, and defining future research priorities in addition to helping in advocacy efforts . These sRoehrborn and colleagues have estimated prostate cancer's economic burden in different countries in their review article in 2011. They estimated the annual cancer's direct costs adjusted to 2010 levels as $136 million for England and Wales, $178 million in Australia, $182 million in Netherlands, and $11 Billion in the US . AnotherThere is a lack of reliable evidence and studies to determine the cost of illness of prostate cancer in low- and middle-income countries, especially the studies which consider both direct and indirect healthcare costs. This study's results may be useful in helping policymakers in Iran and other LMICS to better understand the extent of costs related to this disease and encourage them towards planning an efficient and equitable healthcare system.All estimations were based on data from public hospitals and interview questions. These estimates included economic data, lost labor productivity due to illness, and health indicators. In this study we applied the COI method. This method was developed in more detail by Rice et al. This method shows the social burden of the disease as a quantitative (monetary) value, and since it easily calculates the cost of human capital (lost productivity), it is used more today than other methods. We measured direct and indirect costs of prostate cancer, during the 1 year after the diagnosis –21. We eWe used a prevalence-based approach to estimate the costs. This approach uses the costs of an illness in a given period, regardless of when the disease occurred. This approached was used since it is known that the incidence-based approach underestimates the costs for cancers with a high survival rate. In cost of illness (COI), the structure of human capital is usually targeted by investment based on formal and informal education formulated in the form of skills, knowledge, competence and personal experience. Thus, the individual’s lost productivity related to disease is examined socially –25. A boThe participants in the study were selected from the Ghazi hospital in Tabriz and Labbafinejad Hospital in Tehran, Iran in 2017. Sampling was done consecutively among the patients who came to the Ghazi hospital in Tabriz and Labbafinejad Hospital in Tehran for prostate cancer treatment. The questionnaire was completed during two periods) the first questionnaire was completed in May 2017 and the second questionnaire was completed in August 2017). Questionnaires  were completed for patients who received care or referred for follow-up.We divided direct costs (DC) in our study into medical (DMC) and non-medical costs (DNMC). Direct medical costs were defined as the sum of the costs of diagnostic services (DSC) (such as imaging and cystoscopy), laboratory and pathology services (LC), therapy costs (TC) , in-patient costs (IPC), rehabilitation costs (RC), out-patient costs (OPC) such as physician visits, emergency costs (EC) and costs of medical devices (MDC). Direct non-medical costs included the costs of transportation (TPC), accommodation (AC), and food (FC) attributable to the disease.whereIndirect costs included “absenteeism” (AL), defined as the loss of productivity due to an absence from the workforce including early retirement  as calculated by the human capital method and the loss of productivity due to “premature death”  (MC). Only the income loss and mortality costs of patients below the age of 65 were included in the calculation for indirect costs. The income loss for all patients' companions was included in the calculation regardless of the patients' age. The daily wage of each patient and his/her companion was multiplied by hospitalization days to calculate the income loss  . For theWe calculated the costs from the patient's perspective (PPC) by adding up the out-of-pocket direct costs and the income loss to the patient and his companion.The costs from the society's perspective (SPC) were calculated by summing the value of the direct costs, absenteeism, and mortality costs and multiplying the sum by the prevalence of the disease in the country (P) as reported by the Global Cancer Observatory .\documenThe cost of illness for the financer (FPC) [i.e. insurance fund] was defined as the difference between the real direct costs  and the amount of money paid for them, out of pocket, by the patient.The bills/invoices given to the patients from different providers , in general, included the real costs  of each service. Where the bills did not include these costs, or the patients could only provide us with the data on the out-of-pocket payments, we calculated a ratio (R) for each subtype of health payment  to calculate the total costs. The ratio was calculated by dividing the total costs to out-of-pocket costs within each category, where both were available and non-zero, for each patient and then taking the mean of the results. We then multiplied the out-of-pocket payments by the ratio to estimate the total costs.We gathered all cost data in Iranian Rials (IRR). We converted it to the purchasing power parity (PPP) US dollars (US$-2018) based on the conversion factor of 13,061.2 per US$ for the year of the study calculated by the World Bank .We used the methods proposed by the world health organization (WHO) to calculate the indicators for financial risk protection  .According to this standard, catastrophic expenditure was defined as a household spending ≥ 40% of their annual capacity to pay  on healthcare needs . As a brA total of 297 patients were selected for the study. A summary of patient statistics can be found in Table During the 1 year after the diagnosis, most patients utilized some type of diagnostic (71.7%) and laboratory services (92.6%). Thirty-seven point seven percent (37.7%) of the patients reported the use of therapeutic goods and services. Fifteen point two percent (15.2%) and 28.6% of the patient’s used in-patient and out-patient services, respectively. Rehabilitative services were used by 55.6% of the patients in the period of our study.The total costs and costs by category from the patients' perspective are presented in Tables The costs of illness for society  based on the 1-year prevalence of the disease are presented in Table The costs for insurance companies, which only included direct medical costs are available in Table Five point forty-four percent (5.44%) of households with prostate cancer patient incurred impoverishing health expenditure in our study. However, a much higher proportion of households suffered from catastrophic health expenditures due to costs attributable to prostate cancer with; 31% of them incurring catastrophic health expenditures using the WHO approach (threshold of 40% of the capacity to pay). In the uninsured subset of the population, the proportion was 37.5%. Using the SDG approach, we found that 35% and 50% of the patients and their family members incurred catastrophic health expenditures using the thresholds of 25% and 10% of the total family expenditure, respectively. The results using 10% and 25% thresholds of family income were 32% and 52% incurring catastrophic health expenditures, respectively.Eighteen point seven percent (18.7%) of the households were already below the poverty line, getting pushed further into poverty due to the costs of the illness.Out of the variables included in the logistic regression model , only the age of the patient was found to be a significantly negative determinant of the possibility of catastrophic health expenditures with an odds ratio of 0.98  and a P value of 0.04 . We studied different subcategories of direct and indirect costs and described how much of the total healthcare costs each subcategory accounts for.The high proportion of the uninsured in our study (23.6%) could be one of the major contributors to the high prevalence of catastrophic healthcare expenditure.From the patients’ perspective, direct medical costs were the major contributor to the high costs experienced by patients, as signified by the high proportion of catastrophic expenditures among them.Our results regarding the costs from society’s perspective were comparable to the results in other countries. We calculated the median per-patient direct medical costs to be 5,245$, which was substantially lower than the figures for the USA, Canada, and Italy, but similar to the results for UK, Germany, France, Italy, Spain , 36–38. We found a relatively even distribution of costs between direct and indirect subcategories for society. This finding was consistent with the earlier findings in the US . The majWe found an alarmingly high prevalence of catastrophic healthcare expenditures due to prostate cancer in the country. This finding was consistent across different methods and thresholds of calculating such expenditures. This signifies a need for much better coverage of the costs related to this cancer in the Iranian population, especially regarding the significant sources of expenditure for the patients, including drugs, diagnostic services, and in-patient care.The importance of age in determining the probability of financial catastrophe for the patients can be a result of the effects of the increased costs of illness due to a loss of income in younger patients, as well as the use of costlier treatment options for these patients.Our study has limitations resulting from its bottom-up approach. Misreporting of certain costs and income may occur with this approach. Such an approach, however, is still valuable, as it enables one to gain valuable information directly from the patient, which is not possible when using a top-down approach using, for example, with administrative data. Also, the methodology leads to an issue of the higher likelihood of missing values, which we tried to address by using the available data from the other patients. Furthermore, the patients that were interviewed were being treated in a hospital in a metropolitan area, which might lead to generalizability issues regarding the patients that might have had access issues to such a hospital, such as the rural patients.In conclusion, we have found that the Iranian society, its healthcare financers, and prostate cancer patients incur substantial costs due to prostate cancer. The similarities between our results and the results worldwide show that the country’s situation regarding the effective use of resources is better than in some countries but in need of further improvements. In this time of financial instability in Iran, it is essential to move towards more informed decision making in the healthcare industry to increase the sustainability of healthcare services. Strategic purchasing and performance-based payment systems may be options in this regard. Such approaches combined with the efforts to improve the coverage of different costs associated with prostate cancer may help patients and families to not incur catastrophic costs and impoverishment.Additional file 1: Appendix S1.

This research aims to develop a drug delivery system that effectively treats colitis while administering curcumin/mesalamine by coating alginate/chitosan beads with Eudragit® S-100 to target the colon. Beads were tested to determine their physicochemical characteristics. Coating with Eudragit® S-100 prevents drug release at a pH of less than 7; this was demonstrated by in-vitro release conducted in a medium with gradually varying pH to mimic circumstances in various regions of the gastrointestinal tract. This study examined the efficacy of the coated beads in treating acetic acid-induced colitis in rats. Results showed that spherical beads were formed with an average diameter of 1.6–2.8 mm, and the obtained swelling ranged from 409.80% to 890.19%. The calculated entrapment efficiency ranged from 87.49% to 97.89%. The optimized formula F13  demonstrated the best entrapment efficiency (97.89% ± 1.66), swelling (890.19% ± 60.1), and bead size (2.7 ± 0.62 mm). In formulation #13, which was coated with Eudragit S 100, curcumin (6.01 ± 0.04%) and mesalamine (8.64 ± 0.7%), were released after 2 h at pH 1.2; 6.36 ± 0.11% and 10.45 ± 1.52% of curcumin and mesalamine, respectively, were then released after 4 h and at pH 6.8. Meanwhile, at pH 7.4, after 24 h, approximately 85.34 ± 2.3% (curcumin) and 91.5 ± 1.2%  were released. Formula #13 significantly reduced the colitis, and this suggests that the developed hydrogel beads can be used for delivering curcumin-mesalamine combinations to treat ulcerative colitis after adequate research. The ideal oral colonic delivery method would expedite drug absorption in the upper gastrointestinal tract (GIT) ,2 the st® S-100 (soluble at pH > 7.0) is a popular coating polymer that enables the control of drug release in enteric dosage forms as its solubility changes depending on pH [The process of delivering medications from the stomach to the colon includes using pH-dependent polymers, timed-release dose forms, or carriers that enzymes can digest in the colonic microbiota. Based on pH measurements of the GIT, the idea of utilizing pH as a triggering factor for drug release in the colon was conceived. The pH in the small intestine pH 5.5–6.8) is alkaline, while in the transverse colon, it rises to over pH 7 . For exa.5–6.8 isMesalamine (MSZ) is often used as the first line of defense against ulcerative colitis and Crohn’s disease. MSZ has an anti-inflammatory effect, is the first choice for the treatment of inflammatory bowel diseases, and is used to treat mild to moderate cases because it is generally well-tolerated and safe . It is aCurcuma longa Linn and has been reported to treat inflammation, oxidative stress, and cancer. CUR has demonstrated antiproliferative action with various cancer cell types in vitro, including those from colon, liver, and prostate cancers. The primary mechanism for its anticancer effects is the ability of the curcumin to push cancer cells, including colon cancer, to undergo apoptosis without harming healthy ones One of the major issues with the material is that only 30–40% of the content of curcumin is soluble in water and different techniques must be applied to enhance its solubility [The polyphenolic compound curcumin (CUR) is extracted from turmeric lubility .Hydrogels, such as sodium alginate (SALG), have been widely employed in biomedical applications, particularly in drug delivery. Hydrogel beads have been used as drug carriers in colon-targeting and pH-sensitive coating polymers. By varying their network cross-link density, hydrogels can hold many drugs and control their gradual release .Chitosan (CS), which is the deacetylated derivative of chitin with cationic charge, is another polymer used for this purpose. It is a biocompatible, antibacterial, and biodegradable polymer that has also showed a strong biological adhesion and has contributed to developing enteric delivery systems . The hyd® S-100, are very pH-dependent. Because of its unique pH-solubility profile, Eudragit® S-100has been proposed for use in microencapsulation for controlled-release purposes. This polyacrylic resin is appropriate for drug targeting in the colon since it is pH-sensitive and soluble at pH 7 or above due to the availability of carboxylic acid groups. Hydrogel bead drug delivery systems used for the site-specific transport of MSZ and CUR have been developed using Eudragit® S-100, a pH-responsive enteric polymer, for the efficient prevention of ulcerative colitis [Anionic copolymers of methacrylic acid and methyl methacrylate, such as Eudragit colitis .® S-100-coated CS-SALG (MSZ-CUR) beads for colon targeting was the goal of this work. First, we prepared a complex between the anti-inflammatory drugs (CUR and MSZ) and hydroxypropyl-β-cyclodextrin (HP-β-CD) for improving the low-content drugs’ water solubility, bioavailability, stability, and therapeutic efficacy. Second, we formulated this complex in sodium alginate-based hydrogel formula, in which chitosan was used as a release-controlling agent. A Eudragit® S-100 coating was used on the beads to prevent medication loss in the upper GIT and to deliver drugs to the colon with expected synergistic action for the combination of MSZ-CUR against experimental ulcerative colitis in rats. The beads’ physical characteristics and the in vitro release of the drugs were assessed to test the best formula and then test their anti-inflammatory effectiveness against the rat ulcerative colitis model.Developing pH-sensitive EudragitInclusion complexes between HP-β-CD and the drugs were indicated by comparison of the FTIR spectrums of the inclusion complexes with their corresponding spectra, acquired from their individual ingredients and physical mixture. Changes in the guest molecule’s distinctive bands, such as a removal of or reduction in peak strength, a wave number move, or the emergence of additional bands, may suggest complex formation .−1; sharp bands grouped at 1647, 1614, and 1574 cm−1; and another group of sharp bands at 1487 and 1446 cm−1. The acquired spectrum of HP-β-CD , were constructed with the help of ANOVA using Design-Expert® software (version 11). The response surface models (RSM), and their results were evaluated and validated via statistically significant coefficients with respective R2 values over the whole experimental region to find the compositions of the optimized formulation. Furthermore, the selected experimental domain and RSM equations were validated through the preparation of optimum checkpoint formulations and evaluated to find the optimized formulations.The factorial design has many uses and is highly flexible, which is important when comprehending drug development’s complexity. A variety of independent variables define the quantity of trials that must be run. Further, multiple regression analysis was here used to ascertain the results of each experiment. This study has a simple design with three variables and three experimental levels. We prepared the formulated batches in accordance with the plan and assessed for their various responses. The impact of the variable alone and combined with each response was investigated via multilinear regression analysis and ANOVA testing. All of the generated formulations (22 runs), with triplicate center points and statistical validation quadratic equation of the response’s diameter, swelling studies, and entrapment efficiency , bead size (mm), and swelling (%), were measured to determine the optimum formulation (F13). We compared the detected responses with the predicted responses and estimated the error percentage, as shown in As the concentration of SALG rose, the diameter also increased A,B, whic2, and disintegration took place earlier for those beads formulated in low CaCl2 solution compared to other concentrations of CaCl2 solution. During bead preparation, the concentration of Ca2+ may influence the density of beads’ cross-linking. This result agrees with the findings obtained by another research group [2 concentration was increased , CaCl2 (X2 = 4% w/v), and polymer CS (X3 = 0.5%) values were obtained. These values predict a 2.706 mm diameter, 882.022% swelling and 97.424% EE. The optimized formulation was further characterized to confirm the validity and was found to be within limits , SALG, chitosan, Eudragit® S-100, the optimized form physical mixture, and the optimized prepared beads after drying were acquired (DSC thermograms of the drugs (MSZ-complex and CUR-complex), SALG, chitosan, Eudragitacquired  demonstracquired  showed a® S-100 polymer. For this experiment, Eudragit® S-100 was used to cover the beads. Hydrogel beads encapsulating the drugs were shown to release their contents into simulated GIT fluids. Although the coated hydrogel beads showed promise, their initial drug release was disappointing. After 2 h, a minor fraction of the medicines could be detected in the pH 1.2 media. Only 6.01 ± 0.04% CUR and 8.64 ± 0.7% MSZ were released after 2 h, and 6.36 ± 0.11% CUR and 10.45 ± 1.52% MSZ were released after 4 h at pH 6.8. After 8 h, approximately 85.34 ± 2.3% CUR and 91.5 ± 1.2% MSZ were released at pH 7.4. Since the carboxyl groups in the Eudragit® S-100 polymerize from neutral to alkaline conditions, our results show that the medication was sheltered from gastric acid and enzymes. Ionization compromises the film’s structural integrity, allowing the drug to escape. The membrane layer on the hydrogel beads was dissolved at pH 7.4. The medication was released once the polymer matrix swelled and was eroded.CUR/MSZ combination-loaded beads protected against acetic acid induced ulcerative colitis.Beads of the optimized formula showed very little change in size through five successive weeks at room temperature .® S-100 had entirely dissolved at pH 7, which was achieved at the terminal ileum. Moreover, the C/B ratio of rats given CUR/MSZ-loaded beads was much lower than that of rats given free MSZ or coated MSZ-loaded beads. These results suggested that the simultaneous release of the two medications in the inflamed colonic region might have additive, synergistic effects on the colitis rats, implying that the loading of dual drugs in beads has the potential to reduce the colonic inflammation.Macroscopic colonography was a useful tool for tracking ulcerative colitis’s progression. The level of colon inflammation may be visually evaluated, and the success of treatment can be evaluated in direct correlation with the true inflammatory status of the colon. Representative images for each experimental group are shown in Moreover, coated dual medication-laden beads significantly reduced inflammation levels. The colons of these rats showed mild necrotic changes and hyperemia of the colon. Very little difference could be seen between the colons of these rats and those of healthy rats, save for the absence of inflammation F. These The findings from the C/B ratio and macroscopic observation may be supported by histological assessment. The rats in the healthy group had normal colon anatomy, as shown in ® S-100) to provide a unique colonic delivery system of this combination. Beads were fabricated by ionotropic gelation method for the extended release of a MSZ-CUR combination. FTIR confirmed the interaction between drug molecules and polymer network. We confirmed the chemical stability and molecular dispersion of MSZ and CUR in beads. SEM studies confirmed the presence of pH-sensitive polymers (Eudragit® S-100) on the outer surface of beads. The effect of the incorporation of CaCl2 on the cross-linking of SA chains, swelling studies, and drug release studies were thoroughly examined. The optimized formula F#13 showed the highest uptake of water at pH 7.4 compared to other formulations due to the formation of a less rigid network at a low concentration of SALG 1%. This article demonstrated, for the first time, the formulation of hydrogel beads containing MSZ and CUR complex coated with pH-sensitive polymers . Tri-ethyl citrate (TEC), liquid paraffin, span-80, acetic acid (99%), and sodium hydroxide were purchased from Sigma-Aldrich. Acetone, n-hexane, HCl, Mg-stearate, potassium dihydrogen phosphate, di-sodium-hydrogen-phosphate, methanol, and ethyl alcohol (99%) were procured from El-Nasr Pharmaceutical Co. for Chemicals . Anhydrous calcium chloride (Fine GRG 90%) was supplied by Fisher Scientific .All chemicals were purchased in the analytical grades. Mesalamine, curcumin, SALG, chitosan, hydroxypropyl-β-cyclodextrin (HP-β-CD), and EudragitThe complex stability and stoichiometry constant were determined using the phase solubility approach. Excess quantities of either CUR or MSZ (~30 mg) were transferred to aqueous solutions (each solution was 10 mL) containing different HP-β-CD concentrations (0–10 mM). We irradiated the prepared mixtures in an ultrasonic water bath for 30 min, then left them to sit at 25 °C for 5 days. When an equilibrium had been established, the supernatant solutions were diluted, filtered through a 0.45-µm filter, and then analyzed at 306 and 421 nm using an ultraviolet (UV) spectrophotometer, the Shimadzu UVPC UV-Vis spectrophotometer  to determine the concentrations of MSZ and CUR, respectively, using the appropriate UV standard curve for each compound. We performed triplicate experiments and plotted curves between the concentration of HP-β-CD (x-axis) and concentrations of CUR or MSZ (y-axis). We determined the complexation constants following the technique documented previously .The inclusion complex of CUR/HP-β-CD was formulated using CUR and HP-β-CD at a molar ratio of 1:1. HP-β-CD powder (1.54 g) was transferred into a 50-mL glass beaker followed by the addition of 5 mL of ethyl alcohol, and the mixture was gently stirred until the solubilization of HP-β-CD occurred. Then, 0.368 g of CUR was added to the previous solution and stirred until a transparent solution was obtained. The resulting solution was situated in a fume hood at 25 ± 1 °C for 24 h to slowly evaporate the solvent. The obtained solid residue was sieved through an 80-mesh sieve and preserved in the dark in a desiccator at 25 ± 1 °C [v/v) acetone/water mixture at room temperature with constant magnetic stirring. The resulting MSZ solution was added dropwise to another solution of 1.54 g HP-β-CD in water to formulate the MSZ/HP-β-CD inclusion complex with a 1:1 molar ratio [Meanwhile, MSZ powder (0.153 g) was dissolved in a 2:1  to explore quadratic response surfaces and construct second-order polynomial models. 2 concentration (X2) and CS concentration  spectrophotometer, the Shimadzu UVPC UV-Vis spectrophotometer  and expressed as AQ. The drug encapsulation efficiency was calculated using Equation (2) [The amount of the drugs contained within the beads was calculated using a straightforward method. Hydrogel beads weighing 200 mg were precisely weighed and then crushed for complete drug extraction. The crushed beads were added to the methanol, and the mixture was agitated for a full day at room temperature. The fluid was filtered using a 0.45 µm Milliporetion (2) .(2)DrugThe optimal formula was selected depending on the response variables’ desirability, and it was tested physiochemically and in vitro. Formula #13 was selected as the best formula.® S-100, a colon-targeting, pH-dependent polymer. To coat the formulated beads, we utilized the oil/oil solvent evaporation method. During coating, the dispersion phase was Eudragit® S-100 (5% m/v) dissolved in a 2:1 acetone/ethanol mixture, and we then added the pre-formulated hydrogel beads over 4 h. For the emulsion’s dispersing phase, we used 70 mL of light liquid paraffin and 2% span 80 and stirred them for 3 h at 40 °C (at 1000 rpm). We then filtered the coated beads, rinsed them with n-hexane, sprinkled them with Mg-stearate, and left them to dry at room temperature [The optimized formula of CUR/MSZ hydrogel beads (#13) was coated using S- Eudragitperature .We then The surface and morphologies of hydrogel beads were inspected using Scanning Electron Microscopy (SEM)  .We fixed−1 and 95% transmittance. FTIR spectroscopy was used to detect the presence of interactions and identify changes in functional group composition.Before submitting samples to FTIR analysis, beads were ground into a powder using a mortar and pestle. The material was then placed under an FTIR probe with a range of 4000 to 400 cmThermograms of DSC measurements were taken with DSC 60 Software (60TA-60WS). The phase equilibria, polymorphic transitions, melting, crystallization, and decomposition behaviors of the beads were characterized using DSC analyses. For the DSC procedure, the weight of the dried beads ranged from 3 mg to 7 mg. The studies were carried out in aluminum pans that had been sealed with a cover containing pin holes. A nitrogen flow was used to evaluate the sample at a scan rate of 10 °C per min throughout a temperature range of 25–300 °C. The DSC measured melting point, crystallinity changes, and the presence or absence of drug-carrier-adsorbent interactions.We conducted the drug release experiment in 0.1 N HCl with a pH value equaling 1.2 at 100 rpm for 120 min in a USP apparatus type II  to mimic the conditions in the stomach. For another 2 h, the drug release investigation was conducted in phosphate buffer to simulate the small intestine environment (pH 6.8). A pH 7.4 phosphate solution was utilized for an additional 20 h to simulate the colon. At predefined time intervals until 24 h, 5-mL aliquots were removed and substituted by an equivalent volume of new buffer. All the samples’ medication concentrations were measured at 306 and 421 nm for MSZ and CUR, respectively, using an ultraviolet (UV) spectrophotometer, the Shimadzu UVPC UV-Vis spectrophotometer .The sizes of beads of the optimized formula (F 13) were measured at room temperature using a graduated ruler as a factor to evaluate the physical stability of the beads. The sizes were measured through five successive weeks and the average readings were taken for at least 10 beads. Measurements were conducted in triplicate for the five successive weeks .Male Wistar albino rats were obtained from the animal house at Suez Canal University. The baseline body weight was 170–200 g. We allocated the rats to five experimental groups of five animals each. They were housed at constant relative humidity and temperature and with a normal light-dark cycle, with access to water and commercial pellets ad libitum. Ethics committee at the Faculty of Pharmacy, Suez Canal University, Ismailia, Egypt approved the study protocol in September 2022 (202009PHDA1). The rats were fasted for 24 h before being given colitis-inducing chemicals.v/v) via a soft 6-Fr pediatric catheter into the colon anus  under mild anesthesia  [Ulcerative colitis was induced in rats by injecting 1 mL of acetic acid  . The anuThe drug-loaded beads were administered to the groups two days after induction of ulcerative colitis. For the next eight days, the rats received a single dose daily. They were randomly divided into six groups:® S-100 (curcumin 20 mg/kg). (1): Saline control: received saline solution , (2) UC control, (3) UC + blank beads, (4) UC + free MSZ , (5) UC + coated MSZ beads , (6) UC + optimized formulation beads of CUR/MSZ coated with Eudragitv/v formalin solution and stored for histological examination [Animals were weighed soon before treatment and just before autopsy to see if colitis affected body weight. The animals were slaughtered 24 h after the last medication delivery. We then dissected the full length of the colon and measured its length. After cutting the colon in half lengthwise, rinsing it in cold, normal saline, removing the fat and mesentery, and then blotting the intestines dry with filter paper, the weight was recorded. Colon oedema and inflammatory severity were evaluated using the colon mass index, which was estimated by the division of the colon weight in milligrams by the total body weight in grams. Visual evaluation of ulcer projections was performed, and the specimen was fixed in 10% mination .Luminal content was removed from weighted samples of the colon by opening the samples longitudinally and rinsing them with cold saline solution. Rats’ colon-to-body weight ratios were determined by dividing the colon weight by the overall rat body weight .Colonic damage was measured via histological analysis. The colon specimens were collected from the distal colon and submerged in 10% phosphate buffered formalin before being fixed in paraffin. Hematoxylin and eosin were used to stain sections of 4 um thickness. A pathologist examined the slides for epithelial damage, architectural alterations, mononuclear cell infiltration, and ulceration .

Perhabdovirus isolated in 2022 on perch on a French farm. This virus is genetically related to virus 20/43, which was associated with an outbreak of perch on a farm in France in 2019. Both viruses represent a specific lineage of perch rhabdovirus.We report a nearly full-length genome of a  Perhabdovirus (family Rhabdoviridae) is a genus that includes three viral species, all of which infect fish  isolated in France during a mortality event of farmed European perch in July 2022. This virus is genetically closely related to virus 20/43 previously identified on another farm in the same region in 2019 (ect fish . One spebdovirus –6. We re in 2019 .Perca fluviatilis) were homogenized and inoculated with a culture of BF2 cells. After a few days, a typical cytopathic effect appeared, suggesting the multiplication of a virus, presumably a rhabdovirus. Nucleic acids were extracted from the culture supernatant using a virus nucleospin kit (Macherey-Nagel) and submitted to RT-PCR targeting a large portion of the glycoprotein gene of all Perhabdoviruses  with the homologous sequence of isolate 20/43 originating from perch farmed in another site in the same region.Organs  of sick perch (oviruses . A volumThis resemblance was used to obtain the nearly complete sequence of isolate 22/145 by producing and sequencing PCR tiled amplicons covering the genome.

Potyviridae. While management of the virus and its aphid vectors in agricultural fields decreases virus incidence, many alternative wild hosts for TuMV may serve as source populations for crop infection through spillover. Over thirty years ago, research demonstrated that the introduced brassica, Dame's Rocket  hosts several viruses, including TuMV. Here, we use both enzyme-linked immunosorbent assays (ELISA) and next generation sequencing to document the frequent infection by TuMV of Dame's Rocket, which is common and widespread in disturbed areas around crop fields in upstate New York. Deep sequencing of multiple tissue types of symptomatic hosts indicate that the infection is systemic and causes diagnostic, visible symptoms. In a common garden experiment using host populations from across upstate New York, we found evidence for genetic tolerance to TuMV infection in H. matronalis. Field surveys show that TuMV prevalence varies across populations, but is generally higher in agricultural areas. Examining disease dynamics in this and other common alternative hosts will enhance our understanding of TuMV epidemiology and, more broadly, virus distribution in wild plants.Turnip mosaic virus (TuMV) is a widespread and economically important pathogen in agricultural crops and has the widest known host range in the virus family  Turnip s (TuMV) . In Ford America . This abH. matronalis across multiple landscape types using multiple virus detection tools to assess TuMV prevalence in the expanded range of H. matronalis. We also assess environmental versus genotypic effects on host response to TuMV through experimental infections of H. matronalis. We test the hypotheses that i) flower color breaking and leaf mottling are symptoms of TuMV in H. matronalis and ii) host genotype is a stronger driver of H. matronalis susceptibility to virus infection than host environment.In this study, we survey 22.1We carried out virus surveys in wild brassica populations in June and September 2016 and June 2018 at sites throughout Tompkins, Seneca, Hamilton, Essex and St. Lawrence counties in upstate New York. In 2016 we sampled eleven sites, but the relative size of host clusters in the Adirondack Mountain region  were small compared to those in the Finger Lakes (Seneca and Tompkins counties), and thus an altered sampling method was required in the survey in 2018 (see sampling scheme in Table S3).Brassicaceae in each quadrat. While the survey was primarily focused on assaying H. matronalis, we also included other confamilial hosts whenever they occurred within the quadrats. We tested 434 individual plants for viral infection including individuals of brassica species H. matronalis, Alliaria petiolata, Sinapis arvensis, Brassica rapa and Capsella bursa-pastoris. In subsequent surveys  we focused on H. matornalis only. Leaf tissue from every H. matronalis individual in the sparse Adirondack populations were included in the late 2016 survey . To standardize sampling methods in 2018, equal numbers of H. matronalis plants (N=10 per population) were sampled along 10 meter transects placed randomly through host populations (Table S3).In June 2016, where host groups of similar sizes  could be located, ten replicate 1 meter by 1 meter quadrats were placed approximately 1 meter apart along a transect running from the center to the edge of the cluster. We collected leaf tissue from all plants belonging to family H. matronalis within five meters of an experimental field (not included in the survey) in each region .In both surveys in 2016, we sampled leaf tissue from 50 individuals in each of six large populations in the Finger Lakes region and five populations of smaller size  in the Adirondack region. In 2018, we sampled ∼10 individuals from each of nine populations in the Finger Lakes region and four populations in the Adirondack region, plus full surveys of all volunteer From each host sampled, whole leaves were collected and stored in a cooler for up to 18 hours until they could be frozen in a -30C freezer before analysis. Visible symptoms of virus infection were recorded (presence/absence) and flower color classified as light purple (LP), dark purple (DP), white (W) or color breaking (CB) whenever petal tissue was present. Coordinates and qualitative information about habitat were noted as well.2.2Potyviridae. In the June survey, we used both the general potyvirus assay  which tests for at least 73 potyviruses, as well as the specific TuMV triple antibody sandwich ELISA. By assaying for potyviruses generally, we maintained the largest pool of potential viral species to include in the virus discovery process. Subsequent detection assays in 2018 used only TAS-ELISA specific for TuMV because corresponding positive results between potyvirus and TuMV ELISA tests suggested that TuMV was the primary potyvirus present.During initial virus screening in 2016, we used enzyme linked immunosorbent assays (ELISA) to test whole-leaf samples for four virus species and one virus family: cauliflower mosaic virus (CaMV), turnip yellow mosaic virus (TYMV), cucumber mosaic virus (CMV), turnip mosaic virus (TuMV) and taxa in the family 2.3a priori assumptions about expected virus taxonomy. In spring 2018, fresh tissue was collected from five individual hosts near Cornell University as i) three standardized leaf disks per plant and ii) the pigmented portion of approximately three to five unopened flower buds per plant. Leaf and petal tissue was homogenized separately using liquid nitrogen. In this first assessment of a full H. matronalis virome, four symptomatic individual plants that had both leaf mosaic and color breaking petals were included, and one asymptomatic individual was assayed as a control . Small and micro RNA was extracted from each tissue sample (Qiagen RNeasy Mini kit), quality checked using a fragment analyzer and DNase removed prior to library prep. Library prep and small RNA sequencing on an Illumina HiSeq was done at the Cornell University RNA Sequencing Core. Small RNA (sRNA) sequences (>22 nt) were selected and viral sequences were detected using the VirusDetect bioinformatic platform v1.6 .Inoculum was frozen in a -30C freezer until the beginning of the experiment, then macerated with buffer and introduced to carborundum-abrased leaf tissue. The five remaining individuals per genotype were mock inoculated using distilled water and carborundum power. Inoculations and mock inoculations occurred approximately two weeks after seed germination. Two weeks after inoculation, a leaf sample was taken to test for TuMV infection, and the first week of phenotypic data was collected. For each of the next nine weeks, data were collected on the presence or absence of leaf symptoms , the number of leaves present and the length of the longest leaf over time. Every other week, a new leaf was collected and stored for TAS-ELISA. Leaves collected from weeks two through five were assayed for TuMV infection and symptom development.To partition the effects of genetic and environmental variation among host lines, we conducted a common garden experiment using 19 maternal genotypes of 2.5H. matronalis, we conducted an image analyses of all high-quality individual host occurrence records collected between 2013 and 2020. Presence data was included if the image clearly showed the presence of color breaking flower phenotypes.Presence data from across the realized host range was downloaded from the Global Biodiversity Information Facility (GBIF) in February 2021, cleaned and corrected so that each occurrence included in our study represented a host population rather than a host individual. To estimate the presence of TuMV in 2.62.6.1H. matronalis across upstate New York. In 2016, this was calculated by comparing the number of plants that tested positive for TuMV to the total number of plants sampled over the course of the survey. In 2018, we estimated TuMV prevalence at the host population scale by calculating the number of positive samples out of ten collected at each host population, compared to average prevalence across all samples. We compared positivity rates between regions using a chi-squared test with simulated p-values to create a distribution of expected results.Field surveys were used to estimate the prevalence of TuMV in 2.6.2We assessed the effect of host genotype on plant growth using generalized linear mixed models with a negative binomial distribution to test for interactive and additive differences between common garden host genotypes, populations, regions and treatment throughout and at the end of the experiment. Growth was estimated using mean values of total leaf area per plant by multiplying the number of leaves produced by the longest leaf length. GLMM models were implemented using the glmmTMB package  and lme43H. matronalis across host populations and landscape types. We show that the geographic extent of TuMV infection in the wild plant host H. matronalis is broad, and may be especially common in the Great Lakes region of North America  in A. petiolata and a single infection each in species Sinapis arvenses and Brassica napus.In two separate growing seasons, we tested 1,029 unique individual hosts for TuMV . Across years and samples, 17% of 921 H. matronalis and 20.2% of TuMV negative samples. Furthermore, 13 of the 157 TuMV-positive H. matronalis individuals  were marked as asymptomatic in the field, suggesting that infection does not always induce clearly visible symptoms. As such, it is clear that leaf symptoms alone are not consistent enough to provide definitive diagnostic power. We did not observe color breaking petals in plants that tested negative for TuMV, and thus consider virus-induced color breaking in petals to be a potential diagnostic tool for efficiently monitoring the presence of TuMV. However, the absence of leaf mottling or color breaking does not definitively indicate the absence of the virus.Leaf mottling or crinkling was observed for 81.4% of all TuMV positive individuals of 2=8.06, p-value=.007). In the Finger Lakes region, the overall prevalence of TuMV in 2018 was 34.5% (39 infected of 113 sampled). In the Adirondack samples, the overall prevalence of TuMV in 2018 was 7.5% (3 infected of 40 sampled). Infection rates varied among populations from 0% to 11% in the Adirondacks and 10% to 39% in the Finger Lakes.In our 2018 field survey, we balanced host population size across upstate New York . We founH. matronalis individuals for which full viromes were built, and asymptomatic control tissue yielded no TuMV contigs  virus genome database (Table S2).Deep sequencing of tissue collected in 2018 showed that no other viruses were detected in symptomatic tissue from  contigs . While t3.2Of the 786 plants assayed in 2016, 88 were positive for TuMV, 6 plants in the late season survey were positive for CMV, and none were infected with CaMV or TYMV. All TuMV and CMV infections were detected in plants in the Finger Lakes region; no virus infections were detected in any plant hosts growing in the Adirondacks in 2016. A single plant tested positive for both CMV and TuMV in the late season survey, indicating that coinfections are not especially common.H. matronalis.Viromes built from deep sequencing of leaf and petal tissue from five individual hosts yielded only TuMV viral contigs. Tissue collections for sequencing were made from a single population of hosts, and the sample size is too small to be useful in predicting virus diversity across the broad range of 3.3H. matronalis. To account for host factors that mediate disease severity, we also examined genotypic differences in leaf area under common growing conditions. In our common garden experiment, GLMM analysis indicated some genotypic effects on above-ground biomass . In these agroecological landscapes, common crops like canola grow near weedy species that may be reservoirs for viruses. The probability of spillover between hosts is especially notable for viruses with broad host ranges and non-persistent modes of transmission , which implicates population-level genetic variation in determining the outcome of virus infection. It is possible that hosts that typically experience low levels of virus infection in the field are relatively more susceptible when experimentally infected, as has been observed in other studies . In thisH. matronalis -TuMV pathosystem is widespread across upstate New York and the Great Lakes region, and portions of the midwestern agricultural region of North America have similar landscape characteristics. We recommend further research to determine whether these common hosts are a source or recipient of TuMV spillover between crops and wild hosts, and whether or not management of wild H. matronalis hosts can reduce TuMV-induced disease in crops. Collaboration with farmers and extension agents would facilitate a better assessment of the risk facing farmers in areas where H. matronalis is especially abundant.The 5Hesperis-TuMV pathosystem is common and widespread, particularly in the Great Lakes region of North America, and that it presents a tractable system in which to study plant-virus interactions across environments. In addition, we confirm Ford's hypothesis that color breaking in petals is correlated with virus infection, which can be a complementary method for detecting the presence of TuMV in unmanaged hosts, in addition to molecular diagnostics. Surveys of smaller H. matronalis populations from the Adirondacks region indicate both lower host density and apparent absence of the virus, though this should be monitored. Further work exploring the spatial extent of this pathosystem, mechanisms driving virus dispersal between host populations, and possible virus strain diversity are needed to understand what, if any, role this widespread weedy host might play in crop loss from TuMV.Here, we demonstrate that the This research was funded by a grant to E.M.L. by the Kieckhefer family through Cornell University.E.M.L. conceptualized this study, conducted field research, analyzed results and wrote the first draft of the manuscript.

Vitis rootstocks in different regions of Australia. Most varieties were symptomless on their own roots, while Chardonnay showed a decline in virus-sensitive rootstocks. An isolate of GLRaV-2, on own-rooted Vitis vinifera cv. Grenache, clone SA137, was associated with severe leafroll symptoms after veraison with abnormal leaf necrosis. The metagenomic sequencing results of the virus in two plants of this variety confirmed the presence of GLRaV-2, as well as two inert viruses, grapevine rupestris stem pitting-associated virus (GRSPaV) and grapevine rupestris vein feathering virus (GRVFV). No other leafroll-associated viruses were detected. Among the viroids, hop stunt viroid and grapevine yellow speckle viroid 1 were detected. Of the six phylogenetic groups identified in GLRaV-2, we report the presence of four groups in Australia. Three of these groups were detected in two plants of cv. Grenache, without finding any recombination event. The hypersensitive reaction of certain American hybrid rootstocks to GLRaV-2 is discussed. Due to the association of GLRaV-2 with graft incompatibility and vine decline, the risk from this virus in regions where hybrid Vitis rootstocks are used cannot be overlooked.Grapevine leafroll disease affects the health status of grapevines worldwide. Most studies in Australia have focused on grapevine leafroll-associated viruses 1 and 3, while little attention has been given to other leafroll virus types, in particular, grapevine leafroll-associated virus 2 (GLRaV-2). A chronological record of the temporal occurrence of GLRaV-2 in Australia since 2001 is reported. From a total of 11,257 samples, 313 tested positive, with an overall incidence of 2.7%. This virus has been detected in 18 grapevine varieties and  Closteroviridae family are associated with grapevine leafroll disease. Four of these, i.e., grapevine leafroll-associated virus 1 (GLRaV-1), GLRaV-3, -4, and -13 are in the genus Ampelovirus.

Therefore, it must be considered an important debilitating virus, especially where grafting practice is desired or is mandatory, such as in phylloxera-infested regions where resistant rootstocks are essential.


An outbreak of monkeypox (encoded enveloped double stranded DNA), resurgence and expansion has emerged in early 2022, posing a new threat to global health. Even though, many reports are available on monkeypox, still a comprehensive updated review is needed. Present updated review is focused to fill the research gaps pertaining to the monkeypox, and an extensive search was conducted in a number of databases, including Google Scholar, Scopus, Web of Science, and Science Direct. Although the disease usually progresses self-limiting, some patients require admission for kidney injury, pharyngitis, myocarditis, and soft tissue super infections. There is no well-known treatment available yet; still there has been a push for the use of antiviral therapy and tecovirimat as a promising option when dealing with co-morbidities. In this study, we mapped and discussed the updates and scientific developments surrounding monkeypox, including its potential molecular mechanisms, genomics, transmission, risk factors, diagnosis, prevention, vaccines, treatment, possible plant-based treatment along with their proposed mechanisms. Each day, a growing number of monkeypox cases are reported, and more cases are expected in the near future. As of now, monkeypox does not have a well-established and proven treatment, and several investigations are underway to find the best possible treatment from natural or synthetic drug sources. Multiple molecular mechanisms on pathophysiological cascades of monkeypox virus infection are discussed here along with updates on genomics, and possible preventive and therapeutic strategies. Along wSeveral mammalian species are known to be susceptible to monkeypox, however the native host of the disease is unidentified . From tiEven though many short studies are present, there is a need of study which covers the detailed explanation of the disease along with mechanism involved in it. So, this study was conducted in order to map and summarize upcoming scientific developments surrounding monkeypox, such as its potential molecular insights, genomic patterns, diagnosis, prevention, vaccines, treatment and possible plant-based leads of monkeypox. Presented below is a comprehensive updated review that illustrates a better understanding on monkeypox virus. Understanding the mechanisms involved in monkeypox infection will strengthen the disease preventive and therapeutic strategies along with the discovery of new drugs.2We conducted a review based on scientific articles that addressed monkeypox and its diagnostic method or treatment, especially pharmacological properties Figure 13A non-fatal pox outbreak was first reported in 1958 by Von Magnus in Copenhagen in Cynomolgus macaque (C. macaque). Prior to 1970, no human infection with monkeypox virus had been documented . The fol4Two genetic clades have been identified in monkeypox virus, namely Central African clade (recently renamed as Clade I) and West African clade (recently renamed as Clade II). Furthermore, Clade II has two subclades: IIa and IIb, referring to the set of mutations that are circulating in the 2022 worldwide pandemic. There is a geographic separation between these two clades, as well as a distinction between their epidemiological and clinical characteristics. It has never been documented that West African clade transmits from case to case, and there is a case fatality rate (CFR) of 1%. As a contrast, the Congo Basin clade  exhibits a CFR of 11%, and transmission has been documented up to six times sequentially. It is believed that isolates from West African clade came from Nigeria, Ivory Coast, Liberia, USA, and Sierra Leone (imported from Ghana). On the other hand, isolates from Central African clade come from Congo, Gabon, Central African Republic, Cameroon, Sudan, and DRC. Non-vaccinated individuals of Central African encountered a 10% death rate in the 1980s, while cases occurring in West African strains were not fatal. It has been confirmed that the 2022 monkeypox virus is of West African origin based on preliminary genetic data. Various studies were conducted to compare genomes and was found that nucleotide sequences of the Central African strain (ZAI-96) differ by 0.55-0.56% from those of 3 West African strains . Central and West African strains have 173 and 171 unique functional genes, respectively. In terms of protein sequence, they have about 99.4% identity and share 170 orthologs. Transcription regulatory sequences between the two genomes did not differ significantly. In order to determine which virulence genes are present in both strains, researchers studied 56 virulence genes to determine which are present in both strains, 53 of which were found common to both. 276 substitutions have been found in these 53 genes, accounting for 93 non-conservative changes, 61 conservative changes, and 121 silent changes in amino acid. In total, 16 proteins have extended their N- and C-termini, altering their predicted size. A study reported that BR-203, COP-C3L, and BR-209 orthologs accounted for significant virulence differences between the two strains, which is supported by another study reporting similar gene candidates .Monkeypox virus encoded of all the orthopoxvirus genes known so far, but have only small subsets of the genes related to host range and immunomodulation . MonkeypAlso, an analysis of publicly available genomes from the current human monkeypox virus outbreak of 2022 was conducted to determine the phylogenetic diversity. As compared to previous monkeypox virus outbreaks, this outbreak reveals a distinct monophyletic lineage. Virus outbreaks in Europe may have started as early as March 2022, according to studies. As compared to its related viral predecessors from 2018 and 2019, monkeypox virus 2022 exhibits a marked divergence. In contrast to what is normally observed in orthopoxviruses, the heightened mutational signature this time indicates an accelerated evolutionary path. There has been an increase in cases reported across multiple regions, suggesting that some of these changes in genomics have led to more efficient transmission and dispersal mechanisms, which are compatible with sexual transmission, but research is needed to confirm this assertion. In addition, host-specific mechanisms, like APOBEC enzymatic editing, may be driving this rapid evolution of virus in favor of emergence of a host-specific clade that has enhanced human-to-human transmission capabilities. In light of its continuous spread across different countries and the increasing number of cases reported globally, genomic variability is likely to increase continuously its transmission efficiency .In another study on monkeypox virus genome comparisons, indicate that COP-C3L ortholog, a gene that codes for a complement control protein associated to innate immune response, may play a role in determining the degree of virulence among those strains. One SCR domain is truncated in the Central African ortholog of COP-C3L, which is likely to affect its function, particularly its decay-accelerating ability. The monkeypox strain of Central Africa also contains truncated COP-E3L and COP-K3L, which is similar to the proteins in variola and vaccinia and allows the organism to resist interferons (IFN). Unlike COP-E3L and COP-K3L, monkeypox virus has a full-length ortholog of BR-203 (protein that prevents lymphocytes apoptosis), but variola virus lacks it and vaccinia virus has fragments. The differences between these three orthopoxviruses in terms of virulence may be explained by their proteins differences which affect the host immune system. Research is needed to determine whether genes encoding of proteins fragments with known functions influence its virulence. It may be possible to develop safer vaccines and better therapeutics with such knowledge .5As molecular biology has advanced, we have gained a deeper understanding of how viruses replicate and infect cells. The genome of this organism is relatively larger containing approximately 1,96,858 number of base pairs, which encodes for 190 open reading frames . These ovia a mechanism downstream from apoptosis initiation . Intriguingly, the analysis results indicate that more people are posting positively about the monkeypox virus on social media (28.82%) than posting negatively about it (23.11%). When examining the tweets more closely, most positive tweets about monkeypox was that this virus is not severe and there is a low death rate caused by the disease. There are only few tweets about monkeypox that have negative sentiments suggesting that public hasn’t panicked that much about the virus, and that too negative comments are of people discussing death caused by monkeypox, virus severity, infections caused due to it, whether it can be transmitted, vaccines available, whether it will be the next pandemic after COVID-19, if it is safe to travel, if it will affect the schools functioning, and whether it will affect the people lives. In light of the early stages of this epidemic, researchers and policymakers can use this study to better understand public concerns about monkeypox and develop effective awareness programs and control the outbreak so that general public concerns can be addressed. In order to raise awareness about the ongoing outbreak, it is imperative to teach the general public what the disease symptoms are and when to seek medical attention .7Over the past several years, numerous outbreaks of emerging infectious viral diseases originating from zoonotic animals including MERS-CoV, SARS-CoV-2, H7N9 (avian influenza), chikungunya virus, ebola virus, dengue virus, and Japanese encephalitis virus, which all are highly pathogenic have been reported. From time to time, international travelers reported to spread these viruses. SARS-CoV-2 was spread across countries largely due to international travel. In some non-African countries, monkeypox outbreaks have been reported recently. As of now, there are no links between monkeypox endemic areas and travel found in the current scenario. It is imperative to investigate the root cause of the current outbreaks as soon as possible. Furthermore, the focus must be placed on determining the zoonotic reservoir, zoonosis, spill overs from the host, etc., of this virus. Despite a lack of association between monkeypox outbreaks and air travel, it might be more likely that the disease will spread as a result of air travel as it is a contagious disease .A person who suffers from monkeypox can transmit it to others from the time period of beginning of symptoms until the complete healing of rash and formation of fresh skin layer . The posMoreover, infected human fecal sample can also contain monkeypox virus DNA, according to a recent small study, which may provide yet another potential route for viral transmission. Since some animals (such as rodents) might be infected with the virus as they consume human waste that is laden with the virus, thus causing new infected wild animal populations to establish themselves in traditionally non-endemic areas .Researchers are investigating whether monkeypox can be spread when a person does not have symptoms, or if people with monkeypox symptoms are more likely to spread the virus, and also to determine if the virus is spread more easily through feces, semen, vaginal fluid, or urine of symptomatic patient. To date, the disease seems to be having difficulties spreading effectively, however, the possibility that it can be transmitted through intimate or sexual contact ought to alarm infectious disease specialists in conducting further research to determine how the disease spreads so it can be prevented from spreading worldwide .8Most monkeypox cases are self-limiting, with clinical manifestation as detailed in Asymptomatic infection may occur in some cases, but it is not known to what extent. In the general population, monkeypox has historically had a case fatality rate between 0 and 11%, with a higher rate among younger children. Recent years have seen a 3–6% case fatality rate .As a result of monkeypox associated encephalitis, patients often experience pharyngitis, fever, anorexia, headache, weakness, adenopathy, and a vesiculo-papular rash. A very slow electroencephalogram and diffuse oedema found on cortical magnetic resonance imaging were associated with amplification of meninges in the thalamus and partial cortex as well as signal abnormalities. However, within 5-6 days polymorphonuclear pleocytosis in cerebrospinal fluid (CSF) may decrease and primarily consist of lymphocytes .9When considering the differential diagnosis, other rash illnesses should also be considered, such as measles, chickenpox, scabies, bacterial infections, and medications associated allergies. When monkeypox is in its prodromal stage, lymphadenopathy distinguishes it from chickenpox or smallpox .A monkeypox sample must be collected by health workers and transported safely to a laboratory that has the necessary capabilities if monkeypox is suspected. A laboratory test and the type of specimen determine whether monkeypox is confirmed or not. It is therefore imperative that specimens are packaged and shipped must comply with international and national regulations. In terms of accuracy and sensitivity, polymerase chain reaction (PCR) is the preferred laboratory test. Ideally, monkeypox diagnostic samples should come from skin lesions such as vesicles, pustules, and crusts. Biopsies can be performed where feasible. Keeping lesions cold and storing them in dry and sterile tubes  is essential. But, due to the short duration of viremia, blood tests for PCR are usually inconclusive and should not be routinely conducted in patients of monkeypox after symptoms begin .Also, serological cross-reactivity between orthopoxviruses makes antibody and antigen detection method ineffective from providing monkeypox specific confirmation. Hence it is not recommended to use serology or antigen detection methods for case investigation where resources are limited. Furthermore, a false positive result may also result from recent vaccination with an orthopoxvirus vaccine . So, for interpretation of test results, patient symptoms information must be included with specimens . It may 10Educating people about risk factors and ways to reduce exposure is the primary strategy for preventing monkeypox Figure 5Also to reduce the risk of transmission between humans, surveillance and rapid detection of new cases are crucial for outbreak containment. Standard infection control precautions should be followed by health workers caring for patients or handling specimens from those patients with monkeypox virus infection. The patient should be cared for by persons previously vaccinated against smallpox if possible. Make sure you are using appropriate personal protective equipment (PPE) when caring for those with symptoms, including gloves, a mask, and a gown. Personnel who are trained and equipped with the proper equipment should handle samples suspected of being infected with monkeypox virus. According to WHO guidelines for transporting infectious substances, patient specimens must be packaged triple to ensure their safety . Keep yoFurthermore to prevent monkeypox, some countries have enacted regulations restricting rodent and non-human primate importation. Monkeypox infected captive animals or that might have come into contact with them should be quarantined immediately, handle with standard precautions, and observed for 30 days to monitor monkeypox symptoms .11A specific treatment does not exist for monkeypox viral infections. Monkeypox and smallpox viruses have genetic similarities, so smallpox related antiviral drugs and vaccines may be effective against monkeypox. It is essential that patients receive fluids and food in order to maintain a healthy nutritional status and infections caused by secondary bacteria should be treated accordingly .in vitro  for smallpox, has been now approved by the European Medicines Agency (EMA) for treatment of monkeypox after animal and human studies. Tecovirimat (previously ST-246), a small molecule that inhibits viral egress, has been demonstrated to be effective against vaccinia, cowpox, camelpox, ectromelia (mousepox), and variola viruses . Throughin vitro . In a grin vitro . It was in vitro . Recentlin vitro .Monkeypox can be prevented through vaccination if administered before or soon after exposure. There are currently two monkeypox vaccines available in the USA through the Strategic National Stockpile: JYNNEOS and ACAM2000. For adults 18 years and older, JYNNEOS is licensed. At least four weeks apart, two doses have to be administered in the upper arm. Itching, redness and swelling are the most common reactions people have at the injection site after receiving the JYNNEOS vaccine. Public health has prioritized the JYNNEOS vaccine for the following groups: known close contacts of monkeypox cases identified by case investigations, tracing of contact, and assessments of risk exposure, and for individuals who attended an event where monkeypox was present. Advisory committee on immunization practices(ACIP) also recommends monkeypox vaccinations for laboratory and clinical workers who conduct monkeypox testing and collect monkeypox specimens . MoreoveFurthermore, the Center for Disease Control and Prevention (CDC) recommends administration of vaccinia immune globulin intravenous(VIGIV), cidofovir and Bricidofovir to treat monkeypox. Earlier, VIGIV was used for treating complications caused by vaccinating against vaccinia, such as generalized vaccinia severe, eczema vaccinatum, vaccinia infections among skin diseases, progressive vaccinia and aberrant infections caused by vaccinia virus (except in isolated cases of keratitis). And as an antiviral, FDA has approved cidofovir to treat cytomegalovirus (CMV) retinitis among AIDS patients and Bricidofovir for treating smallpox in adults and children, including neonates since June, 4, 2021. There is a possibility that Bricidofovir has a better safety profile than cidofovir. There have been no serious renal toxic effects or other adverse reactions associated with Bricidofovir treatment for cytomegalovirus infection Figure 5Despite their effectiveness in animal studies against orthopoxviruses, no data indicate that they are effective in humans infected with monkeypox virus. Patients with severe T-cell deficiencies and who are contraindicated from smallpox vaccination after monkeypox exposure should take VIGIV. Cidofovir or brincidofovir should be given to treat monkeypox outbreaks in patients who have severe immunodeficiency . All the12In silico studies have shown that the genome of monkeypox are identical to the central regions that encode essential enzymes and proteins to the genome of smallpox. Despite the fact that monkeypox genome nomenclature resembles universal nomenclature, certain regions differ encoding for virulence. There is a great deal of research being done on the vaccinia virus, as it is used in vaccinations against other types of poxviruses and has lower risk than smallpox. Each of the three agents of monkeypox, smallpox, and vaccinia has nearly 197, 186, and 190kb of genome size respectively. The genomes of all poxviruses are linear and have double-stranded DNAs. Since other poxvirus homologues have similar characteristics and naming problems, the authors of that study refer to their targets by the universal nomenclature gene name based on the vaccinia nomenclature. A50R, A48R, D13L protein trimer complex, F13L, and E are five poxvirus targets examined in that study. A number of studies and reviews have proposed that I7L be used as a useful target for intervention. Based on these targets, an in silico study was conducted on the active residues of monkeypox and eight potential repurposable drugs were identified. In this list of eight drugs, they find nilotinib for A50R, rutaecarpine and NMCT for A48R, naldemedine and hypericin for F13L, simeprevir for D13L, and lixivaptan and fosdagrocorat for I7L. As the drugs show promise in an in silico model, they should also be tested in clinical trials to see if they can combat disease effectively .13®, ST-246, MVA vaccine (IMVANEX® and JYNNEOS®)), four observational studies, and one study to expand access to tecovirimat.

Gaertn, Viscum album L. and Ziziphus mauritiana Lam. were among the most commonly used plants for treating monkey pox in different country regions. As of now, monkeypox does not have a well-established and proven treatment. It is therefore essential to evaluate the molecular mechanism underlying these plant-based treatments and to verify their pharmacological claims in different experimental models as to their ability to mitigate monkeypox virus , the nucleotide sequences of the three West African strains  differ by only 0.55-0.56%. BR-203, BR-209, and COP-C3L orthologs may play a role in the virulence differences between the strains. Multiple molecular mechanisms are stated in this study which explain how monkeypox viruses produce symptoms such as apoptosis by NOXA and caspase-3 upregulation, Bcl-2, PUMA, and PAK2 downregulation, targeting mitochondria, expression of histone, modification of histone posttranslational, dynamic exchanges of chromatin, packaging of DNA, ROCK1 and actin components regulating cytoskeletal dynamics. In order to reduce the risk of future outbreaks, it is imperative to act quickly and stop community transmission. Several key features need to be acknowledged and addressed if we hope to prevent monkeypox and minimize unintentional harms. Additionally, it is likely that an early cluster is responsible for the most cases among men who have sexual relationship with men in the current outbreak It is important to identify monkeypox cases early so that officials of public health can identify potential contacts, their vulnerability, isolate them appropriately, keep track of symptoms, and possibly administer vaccinations. Whenever dermatologists are able to evaluate a patient with papulo-vesiculo-pustular or vesiculo-pustular lesions, should be evaluated for presence of monkeypox. If a diagnosis is suspected or confirmed, public health systems should be contacted quickly. Public health authorities should therefore support those exposed to monkeypox or quarantined monkeypox patients, especially because the pathogen has a prolonged incubation period and is infectious for a long period of time. Studies have revealed the possible plants-based leads to mitigate the monkeypox. These leads should attract the attention and more studies to validate these treatments to help mitigating monkeypox pandemic.RuS, writing – original draft and formal analysis. K-TC, editing.
