The population in Sub Saharan Africa (SSA) suffers poor health as manifested in high mortality rates and low life expectancy. Economic growth has consistently been shown to be a major determinant of health outcomes. However, even with good economic growth rates, it is not possible to achieve desired improvements in health outcomes. Public spending on health (PSH) has long been viewed as a potential complement to economic growth in improving health. However, the relationship between PSH and health outcomes is inconclusive and this inconclusiveness may, in part, be explained by governance-related factors which mediate the impact of the former on the latter. Little empirical work has been done in this regard on SSA. This paper investigates whether or not the quality of governance (QoG) has a modifying effect on the impact of public health spending on health outcomes, measured by under-five mortality (U5M) and life expectancy at birth (LE), in SSA. Using two staged least squares regression technique on panel data from 43 countries in SSA over the period 1996–2011, we estimated the effect of public spending on health and quality of governance U5M and LE, controlling for GDP per capita and other socio-economic factors. We also interacted PSH and QoG to find out if the latter has a modifying effect on the former’s impact on U5M and LE. Public spending on health has a statistically significant impact in improving health outcomes. Its direct elasticity with respect to under-five mortality is between −0.09 and −0.11 while its semi-elasticity with respect to life expectancy is between 0.35 and 0.60. Allowing for indirect effect of PSH spending via interaction with quality of governance, we find that an improvement in QoG enhances the overall impact of PSH. In countries with higher quality of governance, the overall elasticity of PSH with respect to under-five mortality is between −0.17 and −0.19 while in countries with lower quality of governance, it is about −0.09. The corresponding semi elasticities with respect to life expectancy are about 6 in countries with higher QoG and about 3 in countries with lower QoG. Public spending on health improves health outcomes. Its impact is mediated by quality of governance, having the higher impact on health outcomes in countries with higher quality of governance and lower impact in countries with lower quality of governance. This may be due to increased efficiency in the use of available resources and better allocation of the same as QoG improves. Improving QoG would improve health outcomes in SSA. The same increase in PSH is twice as effective in reducing U5M and increasing LE in countries with good QoG when compared with countries with poor QoG.

Objective: We aimed to quantify the relationship between national income and infant and under-five mortality in developing countries. Design: We conducted a systematic literature search of studies that examined the relationship between income and child mortality (infant and/or under-five mortality) and meta-analysed their results. Setting: Developing countries. Main outcome measures: Child mortality (infant and /or under-five mortality). Results: The systematic literature search identified 24 studies, which produced 38 estimates that examined the impact of income on the mortality rates. Using meta-analysis, we produced pooled estimates of the relationship between income and mortality. The pooled estimate of the relationship between income and infant mortality before adjusting for covariates is −0.95 (95% CI −1.34 to −0.57) and that for under-five mortality is −0.45 (95% CI −0.79 to −0.11). After adjusting for covariates, pooled estimate of the relationship between income and infant mortality is −0.33 (−0.39 to −0.26) while the estimate for under-five mortality is −0.28 (−0.37 to −0.19). If a country has an infant mortality of 50 per 1000 live births and the gross domestic product per capita purchasing power parity increases by 10%, the infant mortality will decrease to 45 per 1000 live births. Conclusion: Income is an important determinant of child survival and this work provides a pooled estimate for the relationship.

Antiretroviral therapy (ART) has led to increased survival of children with vertically acquired human immunodeficiency virus infection. Significant morbidity arises from respiratory symptoms, but aetiology and pulmonary function abnormalities have not been systematically studied. Human immunodeficiency virus-positive children aged 8–16 years were systematically recruited within clinics in Blantyre, Malawi. Clinical review, quality of life assessment, spirometry, and chest radiography were performed. One hundred sixty participants had a mean of age 11.1 (range, 8–16) years and 50.0% were female. Cough was present in 60 (37.5%) participants, and 55 (34.4%) had moderate or severe dyspnoea. Thirty-four (22.1%) participants had digital clubbing. Thirty-three (20.6%) participants were hypoxic at rest. One hundred eighteen (73.8%) of the children were receiving ART; median CD4 count was 698 cells/µL in these compared with 406 cells/µL in ART-naive individuals ( P < .001). From 145 spirometry traces (90.6%), mean forced expiratory volume in 1 second (FEV 1 ) and forced vital capacity ( FVC) were 1.06 and 0.89 standard deviations below predicted mean, respectively. Twenty-one (14.5%) traces demonstrated obstructive defects and 26 (17.9%) reduced FVC. Lung function abnormality was not associated with any clinical findings. Of the 51 individuals with abnormal lung function, the mean increase in FEV 1 after salbutamol was 3.8% (95% confidence interval, 0.02–7.53). “Tramlines” and ring shadows were seen on chest radiographs in over half of cases. Symptoms of chronic lung disease were highly prevalent with 2 main clinical phenotypes: “cough” and “hypoxia”. Lung function abnormalities are common, poorly responsive to bronchodilators, and apparent throughout the age range of our cohort. Pathological causes remain to be elucidated. Cough and hypoxic phenotypes could be a useful part of diagnostic algorithms if further validated.

Infection with HIV, and oftentimes coinfection with TB, complicates the care of severely malnourished children in sub-Saharan Africa. These superimposed infections challenge clinicians faced with a population of malnourished children for whose care evidence-based guidelines have not kept up. Even as the care of HIV-uninfected malnourished children has improved dramatically with the advent of community-based care and even as there are hopeful signs that the HIV epidemic may be stabilizing or ameliorating, significant gaps remain in the care of malnourished children with HIV. Here we summarize what is currently known, what remains unknown, and what remains challenging about how to treat severely malnourished children with HIV and TB.

Aims and Objectives: To determine if a team dedicated to basic neonatal resuscitation in the delivery ward of a teaching hospital would impact the outcome of neonates delivered in Kampala, Uganda. Methods: A five-member team of nurses, trained in basic neonatal resuscitation attended 1046 deliveries over a thirty-one day pilot period. They were available in the delivery ward twenty-four hours each day. Outcomes studied included the number of stillbirths recorded on the delivery ward, the number of neonates admitted to the special care baby unit (SCBU), the number of babies admitted to SCBU who died and the mortality in the different weight categories. APGAR scores before and after intervention was also compared. Admission diagnoses between the two groups were also compared. Outcome data collected during this pilot period was compared with historic controls from the previous 31 days in the same unit. Patients and Setting: A delivery ward, 22 000 deliveries per year. Results: The stillbirth rate and admission rate to the SCBU were unchanged. Basic neonatal resuscitation in this setting decreased the incidence of asphyxia (defined as failure to initiate and sustain breathing or an APGAR score of <7 at 5 min), improved APGARS and a decrease in the mortality of babies weighing more than 2 kg. Conclusion: The resuscitation team reduced the incidence of and mortality from asphyxia and improved the outcome of babies greater than 2 kg. This pilot study provides evidence of the beneficial effect of basic neonatal resuscitation in this setting.
