Appealing to altruism: an alternative strategy to address the health workforce crisis in developing countries?
BACKGROUND
Recruitment and retention of health workers is a major concern. Policy initiatives emphasize financial incentives, despite mixed evidence of their effectiveness. Qualitative studies suggest that nurses especially may be more driven by altruistic motivations, but quantitative research has overlooked such values. This paper adds to the literature through characterizing the nature and determinants of nurses' altruism, based on a cross-country quantitative study.


METHODS
An experimental 'dictator game' was undertaken with 1064 final year nursing students in Kenya, South Africa and Thailand between April 2007 and July 2008. This presents participants with a real financial endowment to split between themselves and another student, a patient or a poor person. Giving a greater share of this financial endowment to the other person is interpreted as reflecting greater altruism.


RESULTS
Nursing students gave over 30% of their initial endowment to others (compared with 10% in similar experiments undertaken in other samples). Respondents in all three countries showed greater generosity to patients and the poor than to fellow students.


CONCLUSIONS
Consideration needs to be given to how to appeal to altruistic values as an alternative strategy to encourage nurses to enter the profession and remain, such as designing recruitment strategies to increase recruitment of altruistic individuals who are more likely to remain in the profession.

Macroeconomic impact of pandemic influenza and associated policies in Thailand, South Africa and Uganda
BACKGROUND
Research has shown the value of conducting a macroeconomic analysis of the impact of influenza pandemics. However, previous modelling applications focus on high-income countries, and there is a lack of evidence concerning the potential impact of an influenza pandemic on lower- and middle-income countries.


OBJECTIVES
To estimate the macroeconomic impact of pandemic influenza in Thailand, South Africa and Uganda with particular reference to pandemic (H1N1) 2009.


METHODS
A single-country whole-economy Computable General Equilibrium (CGE) model was set up for each of the three countries in question and used to estimate the economic impact of declines in labour attributable to morbidity, mortality and school closure.


RESULTS
Overall GDP impacts were less than 1% of GDP for all countries and scenarios. Uganda's losses were proportionally larger than those of Thailand and South Africa. Labour-intensive sectors suffer the largest losses.


CONCLUSION
The economic cost of unavoidable absence in the event of an influenza pandemic could be proportionally larger for low-income countries. The cost of mild pandemics, such as pandemic (H1N1) 2009, appears to be small, but could increase for more severe pandemics and/or pandemics with greater behavioural change and avoidable absence.

Macroeconomic impact of a mild influenza pandemic and associated policies in Thailand, South Africa and Uganda: a computable general equilibrium analysis
Background Previous research has demonstrated the value of macroeconomic analysis of the impact of influenza pandemics.

Medical tourism: a review of the literature and analysis of a role for bi-lateral trade.
OBJECTIVES
With increasing globalization, many countries are considering opening their health systems to greater cross-border movement of patients. This is usually done from the viewpoint of a multi-lateral trade relationship. This paper considers the issues that arise from this debate from a bi-lateral perspective.


METHODS
A systematic literature review was carried out on 'Medical Tourism' from the perspective of a bi-lateral trade relationship, using the UK and India as a case study.


RESULTS
There is a dearth of data and discussion on such bi-lateral trade. This limited evidence offers some suggestions. Exporting countries may benefit from medical tourism by generating foreign exchange and reversing the brain drain, but run the risk of creating a dual system, where the local population is crowded out. Importing countries can benefit from alleviating waiting lists and lowering healthcare costs, but may risk quality of care and legal liability. However, evidence from a bi-lateral perspective suggests that the positive aspects can be capitalised, and the negative ones reduced.


CONCLUSIONS
The key recommendations from this paper are for more evidence to be collected at the country and international level, and for countries to consider trade in health services from a bi-lateral rather than multi-lateral perspective.

The relationship between reliability and size of willingness-to-pay values: a qualitative insight.
In a previous paper, the reliability of willingness-to-pay (WTP) values was found to be an increasing function of the size of WTP expressed. Here, the results of a qualitative exercise conducted alongside this quantitative study are presented. The results of this exercise suggest that higher WTP values may require more thought from the respondent which, in turn, gives them greater stability. At low levels of WTP, values appear to be taken from a 'discretionary account', where expenditure is more volatile. Caveats to this result, and suggestions for future research, are considered in the discussion.

Foreign direct investment and trade in health services: a review of the literature.
Globalization is a key challenge facing health policy-makers. A significant aspect of this is direct trade in health services, a result of the rise of transnational corporations, challenges in health care financing, porous borders and improved technology creating the scope for increased 'foreign direct investment' (FDI) in health care. This has gathered momentum with the General Agreement on Trade in Services (GATS), which aims to further liberalize trade in services, and within which FDI has been noted as perhaps the most critical area for trade negotiation. Given the rapid development of this area, there are little empirical data. This paper therefore seeks to provide the first comprehensive and systematic review of evidence concerning FDI and health services. This process included electronic bibliographic database searches, website searches and correspondence with experts in the area of trade in health services, from which 76 papers, books and reports were reviewed. Perhaps due to the rapid developments in this area, most of the literature is speculative, polarized between those arguing for the benefits of liberalization and those arguing against. However, there seem to be three issues which emerge as of most importance: (i) the extent to which a national health system is commercialized per se is of more significance than whether investment in it is foreign or domestic; (ii) the national regulatory environment and its 'strength' will significantly determine the economic and health impact of FDI, the effectiveness of safeguard measures, and the stability of GATS commitments; and (iii) any negotiations will depend upon parties having a common understanding of what is being negotiated, and the interpretation of key definitions is thus critical. Each of these issues is explored in some depth, with the overall conclusion that countries should take a step back and first think through the risks and benefits of commercialization of their health sector, rather than being sidetracked in to considering the level of foreign investment.

Hormone trajectories leading to human birth
The mechanisms regulating human parturition and labor remain unknown. This ignorance is expensive as preterm birth is responsible for 70% of neonatal mortality and 50% of cerebral palsy. Methods for the prediction of preterm birth and treatments for women in preterm labor have poor efficacy reflecting our limited knowledge of the mechanisms involved. Recent research has supported the view that parturition is a cascade of events that commences early in pregnancy and involves the mother, fetus, placenta, membranes, cervix and myometrium. Although a number of the key hormones and proteins involved have been identified, the relationships between these factors in time and tissues remain unclear. Placental production of Corticotropin-releasing hormone (CRH) is proposed as an early event regulating the cascade of events. Central to the onset of parturition will be a mechanism for progesterone withdrawal and estrogen activation in human. Two forms of progesterone receptor with opposing actions exist in the human myometrium. Progesterone receptor A (PR-A) is a dominant negative repressor of progesterone receptor B (PR-B). Preliminary studies strongly support the hypothesis that the onset of human parturition is initiated by rising concentrations of PR-A in the myometrium.

Unexplained antepartum stillbirth: a consequence of placental aging?
Unexplained antepartum stillbirth is a major obstetric health problem. Data demonstrate a rapid rise in risk per 1000 continuing pregnancies as gestation advances beyond 40 weeks. We review the evidence that such stillbirths are a consequence of aging related changes in the late gestation placenta. We suggest that the relatively small number of continuing pregnancies after 40 completed weeks means that negative effects of genes that produce aging affect so few pregnancies that polymorphisms in genes that produce these effects are retained in the population. Aging related changes likely represent a consequence of the damaging effects of oxidative stress, increased by cigarette smoking counteracted by the mitigating effects of oxidative defence pathways. The aging related changes are likely downstream from nutrient sensing units such as mTOR and include effects on production of telomerase and consequent shortening of telomere length. The late gestation changes occur in the context of increasing fetal growth and nutrient supply demands that can produce the rapid development of a mismatch between placental supply and fetal need resulting in fetal demise. Premature aging may also play an important role in antepartum stillbirth occurring earlier in pregnancy, especially in the context of growth restriction.

The effect of repetitive haemorrhage on plasma cortisol, beta-endorphin and N-terminal pro-opiomelanocortin in conscious sheep.
We measured the effect of repeated haemorrhagic stress, performed on four consecutive days in conscious adult sheep, on the plasma concentrations of cortisol and ACTH-related peptides to determine whether the pituitary-adrenal response was altered by stress repetition. Peptides from the C-terminus of the ACTH pro-hormone was measured by beta-endorphin RIA. Glycopeptides derived from the N-terminus of the ACTH pro-hormone were measured by tau 3-MSH RIA. The immunoreactive tau 3-MSH in sheep plasma was found to have an apparent molecular weight of approximately 10,000 by gel chromatography through Sephadex G-75, which is similar to the size of the major circulating form of pro-tau-MSH found in human and rat plasma. Daily haemorrhage consistently elevated plasma concentrations of cortisol and pro-tau-MSH. There was no significant difference in the daily responses of either cortisol or pro-tau-MSH when considered individually. However, there was a significant change over the four days in the relationship between the cortisol and pro-tau-MSH responses, as judged by analysis of variance of the difference in daily z-scores of cortisol and pro-tau-MSH. This trend indicated a relative increase in the secretion of pro-tau-MSH from the pituitary compared to the cortisol response, and suggested that repeated exposure to stressful stimuli may alter the pituitary-adrenal-axis.
