Interrogating the World Bank's role in global health knowledge production, governance, and finance.

BACKGROUND: In the nearly half century since it began lending for population projects, the World Bank has become one of the largest financiers of global health projects and programs, a powerful voice in shaping health agendas in global governance spaces, and a mass producer of evidentiary knowledge for its preferred global health interventions. How can social scientists interrogate the role of the World Bank in shaping 'global health' in the current era? MAIN BODY: As a group of historians, social scientists, and public health officials with experience studying the effects of the institution's investment in health, we identify three challenges to this research. First, a future research agenda requires recognizing that the Bank is not a monolith, but rather has distinct inter-organizational groups that have shaped investment and discourse in complicated, and sometimes contradictory, ways. Second, we must consider how its influence on health policy and investment has changed significantly over time. Third, we must analyze its modes of engagement with other institutions within the global health landscape, and with the private sector. The unique relationships between Bank entities and countries that shape health policy, and the Bank's position as a center of research, permit it to have a formative influence on health economics as applied to international development. Addressing these challenges, we propose a future research agenda for the Bank's influence on global health through three overlapping objects of and domains for study: knowledge-based (shaping health policy knowledge), governance-based (shaping health governance), and finance-based (shaping health financing). We provide a review of case studies in each of these categories to inform this research agenda. CONCLUSIONS: As the COVID-19 pandemic continues to rage, and as state and non-state actors work to build more inclusive and robust health systems around the world, it is more important than ever to consider how to best document and analyze the impacts of Bank's financial and technical investments in the Global South.

Differential Ratings of Perceived Match and Training Exertion in Girls' Soccer.

PURPOSE: To understand the validity of differential ratings of perceived exertion (dRPE) as a measure of girls' training and match internal loads. METHODS: Using the centiMax scale (CR100), session dRPE for breathlessness (sRPE-B) and leg muscle exertion (sRPE-L) were collected across a season of training (soccer, resistance, and fitness) and matches from 33 players (15 [1] y). Differences and associations between dRPE were examined using mixed and general linear models. The authors' minimal practical important difference was 8 arbitrary units (AU). RESULTS: Mean (AU [SD] ∼16) sRPE-B and sRPE-L were 66 and 61 for matches, 51 and 49 for soccer, 86 and 67 for fitness, and 45 and 58 for resistance, respectively. Session RPE-B was rated most likely harder than sRPE-L for fitness (19 AU; 90% confidence limits: ±7) and most likely easier for resistance (-13; ±2). Match (5; ±4) and soccer (-3; ±2) differences were likely to most likely trivial. The within-player relationships between sRPE-B and sRPE-L were very likely moderate for matches (r = .44; 90% confidence limits: ±.12) and resistance training (.38; ±.06), likely large for fitness training (.51; ±.22), and most likely large for soccer training (.56; ±.03). Shared variance ranged from 14% to 35%. CONCLUSIONS: Practically meaningful differences between dRPE following physical training sessions coupled with low shared variance in all training types and matches suggest that sRPE-B and sRPE-L represent unique sensory inputs in girls' soccer players. The data provide evidence for the face and construct validity of dRPE as a measure of internal load in this population.

Effectiveness of mass oral cholera vaccination in Beira, Mozambique.

BACKGROUND: New-generation, orally administered cholera vaccines offer the promise of improved control of cholera in sub-Saharan Africa. However, the high prevalence of human immunodeficiency virus (HIV) infection in many cholera-affected African populations has raised doubts about the level of protection possible with vaccination. We evaluated a mass immunization program with recombinant cholera-toxin B subunit, killed whole-cell (rBS-WC) oral cholera vaccine in Beira, Mozambique, a city where the seroprevalence of HIV is 20 to 30 percent. METHODS: From December 2003 to January 2004, we undertook mass immunization of nonpregnant persons at least two years of age, using a two-dose regimen of rBS-WC vaccine in Esturro, Beira (population 21,818). We then assessed vaccine protection in a case-control study during an outbreak of El Tor Ogawa cholera in Beira between January and May 2004. To estimate the level of vaccine protection, antecedent rates of vaccination were compared between persons with culture-confirmed cholera severe enough to have prompted them to seek treatment and age- and sex-matched neighborhood controls without treated diarrhea. RESULTS: We assessed the effectiveness of the vaccine in 43 persons with cholera and 172 controls. Receipt of one or more doses of rBS-WC vaccine was associated with 78 percent protection (95 percent confidence interval, 39 to 92 percent; P=0.004). The vaccine was equally effective in children younger than five years of age and in older persons. A concurrently conducted case-control study designed to detect bias compared persons with treated, noncholeraic diarrhea and controls without diarrhea in the same population and found no protection associated with receipt of the rBS-WC vaccine. CONCLUSIONS: The rBS-WC vaccine was highly effective against clinically significant cholera in an urban sub-Saharan African population with a high prevalence of HIV infection.

Is HIV infection associated with an increased risk for cholera? Findings from a case-control study in Mozambique.

OBJECTIVE: As residents of sub-Saharan Africa are at high risk for HIV and cholera, it is biologically plausible that immune suppression caused by HIV infection predisposes to cholera. Our aim was to assess the potential association between both diseases. METHODS: We conducted a case-control study in Beira, Mozambique, a high-risk area for HIV and cholera. Between 1 January 2005 and 30 June 2006, experienced counsellors invited 132 suspected cholera cases and 528 age- and sex-matched controls to an HIV counselling and testing centre. RESULTS: Forty (30%) of the invited cases and 127 (24%) of the invited controls came for HIV testing. No significant differences in demographic and socio-economic baseline characteristics were detected between participants and non-participants. Twenty five of 167 (15%) individuals who underwent testing were found HIV-positive. The probability of a positive HIV-test was highest in participants between 40 and 49 years; 6 of 14 (43%) tested HIV-positive. Nine of 40 (23%) cholera cases were found to be HIV-infected compared with 16 of 127 (13%) controls (adjusted odds ratio 2.6; 95% CI 0.9-7.5; P = 0.08). DISCUSSION: The findings suggest that in a cholera-endemic area, HIV infection is associated with an increased risk for cholera. More research in HIV endemic settings is needed to confirm the findings and to explore the effect of HIV-related immunosuppression on the transmission of cholera.

Countdown to 2015: tracking intervention coverage for child survival.

BACKGROUND: The fourth Millennium Development Goal (MDG) calls for a two-thirds' reduction between 1990 and 2015 in deaths of children younger than five years; achieving this will require widespread use of effective interventions, especially in poor countries. We present the first report of the Child Survival Countdown, a worldwide effort to monitor coverage of key child-survival interventions in 60 countries with the world's highest numbers or rates of child mortality. METHODS: In 2005, we developed a profile for each of the 60 countries to summarise information on coverage with essential child survival interventions. The profiles also present information on demographics, nutritional status, major causes of death in children under 5 years of age, and the status of selected health policies. Progress toward the fourth MDG is summarised by comparing the average annual rate of reduction in under-5 mortality in each country with that needed to achieve the goal. The profiles also include a comparison of the proportions of children in the poorest and richest quintiles of the population who received six or more essential prevention interventions. Each country's progress (as measured by defined indicators of intervention coverage) was put into one of three groups created on the basis of international targets: "on track"; "watch and act"; and "high alert". For indicators without targets, arbitrary thresholds for high, middle, and low performance across the 60 countries were used as a basis for categorisation. FINDINGS: Only seven countries are on track to met MDG-4, 39 countries are making some progress, although they need to accelerate the speed, and 14 countries are cause for serious concern. Coverage of the key child survival interventions remains critically low, although some countries have made substantial improvements in increasing the proportion of mothers and children with access to life saving interventions by as much as ten percentage points in 2 years. Children from the poorest families were less likely than those from wealthier families to have received at least six essential prevention interventions. INTERPRETATION: Our results show that tremendous efforts are urgently needed to achieve the MDG for child survival. Profiles for each country show where efforts need to be intensified, and highlight the extent to which prevention interventions are being delivered equitably and reaching poor families. This first report also shows country-specific improvements in coverage and highlights missed opportunities. The "Countdown to 2015" will report on progress every 2 years as a strategy for increasing accountability worldwide for progress in child survival.

Health research, the MDGs and policy making in Mozambique.

Health research can play an important part in achieving the goals of improving health, economic development and reducing poverty, even though a review of the literature suggests that little attention is given to the subject. Mozambique as a developing country has scarce resources for health research and so its health research efforts need targeted at pressing concerns and be capable of influencing policy-making. A way forward is being developed so that position of policy-makers and researchers is clarified and co-ordination better organised. This will also involve a review of financing, formulation of agendas, the avoidance of wasted resources and improving management skills.

Quality of registration of maternal deaths in Mozambique: a community-based study in rural and urban areas.

Maternal mortality is an important indicator used to assess the level of development of a country and particularly the coverage of health services. In Africa where the maternal mortality ratios are about 100 times higher than those of developed countries the situation is even worse due to problems of underregistration. In Mozambique the figures officially used are derived from the data of some hospitals in the main cities. This leaves out the 60% of pregnant women who do not attend health facilities. It was against this background that the present study was designed to be a prospective community-based study carried out in the central region of Mozambique involving a population of 207,369 inhabitants. The study covered a 12-month period, from 01/08/96 to 31/07/97 and found 214 deaths among women in reproductive age (15-49 yr) of whom 40 were classified as maternal deaths. Gross underregistration was revealed, as the health institutions failed by 86% in recording maternal deaths, the same happening with other official sources, like the Civil Register and the Funeral Services registering only 9% of the maternal deaths. This kind of study is however complex and labour intensive and a practical way of monitoring has to be found; for the region where the study took place close collaboration with private cemeteries appears to be a way to be further explored.

From safe motherhood, newborn, and child survival partnerships to the continuum of care and accountability: moving fast forward to 2015.

The present paper provides an overview of the Safe Motherhood Initiative, Healthy Newborn Partnership, and Child Survival Partnership and their eventual merge into the Partnership for Maternal, Newborn and Child Health (PMNCH) in 2005. The promise and past successes of the PMNCH are highlighted, with a particular focus on the PMNCH's partner-centric approach showing the importance of collaboration for progress. The aims of the strategic framework for 2012-2015 are presented within the context of the Global Strategy for Women's and Children's Health, launched in 2010, and growing political momentum to achieve Millennium Development Goals 4 and 5 (reduce child mortality and improve maternal health, respectively). The next 4 years leading to 2015 are critical, and the global community must continue to work together to ensure all women and children are reached with key interventions proven to reduce mortality.

Classical RS1 and environmental RS1 elements in Vibrio cholerae O1 El Tor strains harbouring a tandem repeat of CTX prophage: revisiting Mozambique in 2005.

Currently, Vibrio cholerae O1 serogroup biotype El Tor strains producing classical type cholera toxin (altered strains or El Tor variants) are prevalent in Asia and in Mozambique. Mozambican strains collected in 2004 contained a tandem repeat of CTX prophage on the small chromosome and each CTX prophage harboured the classical rstR and classical ctxB. We found that the majority of the strains collected in 2005 in Mozambique contained extra elements on the large chromosome in addition to the tandem repeat of CTX prophage on the small chromosome. New type RS1 elements RS1(cla) and RS1(env), and a CTX(env) with rstR(env) and the classical ctxB were identified on the large chromosome of the Mozambican isolates collected in 2005.

Private demand for cholera vaccines in Beira, Mozambique.

In the summer of 2005, we interviewed 996 randomly selected respondents in Beira, Mozambique concerning their willingness and ability to pay for cholera vaccine for themselves and for other household members. Respondents were told that two doses of the vaccine would be required 2 weeks apart, and that the cholera vaccine would offer excellent protection against infection for the first year following vaccination, and some protection during the second and third year after a person is vaccinated. This research was carried out in order to learn more about private demand for vaccines in a cholera-endemic area. We asked two types of valuation questions: (1) a discrete-price offer for a vaccine that could be purchased for household members and (2) a payment card designed to assess uncertainty in the respondent's demand for a vaccine for self-protection. We estimate average household willingness to pay (WTP) for cholera vaccines in Beira to be 2005 US$ 8.45. This estimate of household WTP represents the perceived private economic benefits to a household--six persons on average--of giving all members free cholera vaccines.

Feasibility of a mass vaccination campaign using a two-dose oral cholera vaccine in an urban cholera-endemic setting in Mozambique.

We conducted a study to assess the feasibility and the potential vaccine coverage of a mass vaccination campaign using a two-dose oral cholera vaccine in an urban endemic neighbourhood of Beira, Mozambique. The campaign was conducted from December 2003 to January 2004. Overall 98,152 doses were administered, and vaccine coverage of the target population was 58.6% and 53.6% for the first and second rounds, respectively. The direct cost of the campaign, which excludes the price of the vaccine, amounted to slightly over 90,000 dollars, resulting in the cost per fully vaccinated person of 2.09 dollars, which is relatively high. However, in endemic settings where outbreaks are likely to occur, integrating cholera vaccination into the routine activities of the public health system could reduce such costs.
