RESUMEN
Ras-related Rap1A GTPase is implicated in pancreas ß-cell insulin secretion and is stimulated by the cAMP sensor Epac2, a guanine exchange factor and activator of Rap1 GTPase. In this study, we examined the differential proteomic profiles of pancreata from C57BL/6 Rap1A-deficient (Null) and control wild-type (WT) mice with nanoLC-ESI-MS/MS to assess targets of Rap1A potentially involved in insulin regulation. We identified 77 overlapping identifier proteins in both groups, with 8 distinct identifier proteins in Null versus 56 distinct identifier proteins in WT mice pancreata. Functional enrichment analysis showed four of the eight Null unique proteins, ERO1-like protein ß (Ero1lß), triosephosphate isomerase (TP1), 14-3-3 protein γ, and kallikrein-1, were exclusively involved in insulin biogenesis, with roles in insulin metabolism. Specifically, the mRNA expression of Ero1lß and TP1 was significantly (p < 0.05) increased in Null versus WT pancreata. Rap1A deficiency significantly affected glucose tolerance during the first 15-30 min of glucose challenge but showed no impact on insulin sensitivity. Ex vivo glucose-stimulated insulin secretion (GSIS) studies on isolated Null islets showed significantly impaired GSIS. Furthermore, in GSIS-impaired islets, the cAMP-Epac2-Rap1A pathway was significantly compromised compared to the WT. Altogether, these studies underscore an essential role of Rap1A GTPase in pancreas physiological function.

BACKGROUND: Healthcare service delivery systems need to ensure standard quality of care (QoC) for achieving expected health outcomes. Although Bangladesh has a good healthcare service delivery system, there are major concerns about the quality of maternal and newborn health (MNH) care services, which is imperative for achievements in health. The study aimed to measure the QoC for different MNH services in two selected public health facilities of Bangladesh. This study also documented the specific areas of each care which needs intervention. METHODS: The study was conducted in two district-level public health facilities-a district hospital (DH) and a mother and child welfare centre (MCWC). A total of 228 cases of MNH services were observed by using contextualized checklist 'Standards-based Management and Recognition (S-BMR)' for 8 selected MNH care services. For scoring, performed activities were calculated as percentages of the total recommended activities and categorized as high (> 80%), moderate (50 to 80%), and low (< 50%). RESULTS: Overall QoC scores were moderate for each DH (54.8%), and MCWC (56.1%). In DH, the QoC score was high for blood transfusion (80.3%); moderate for maternal complications management (77.0%), caesarean section (CS) (65.6%), infection prevention (64.3%), sick newborn care (54.1%), and normal vaginal delivery (NVD) (52.6%); and low for antenatal care (ANC) (25.6%) and postnatal care (PNC) (19.0%). In MCWC, the QoC scores were high for infection prevention (83.0%); moderate for CS (76.5%) and NVD (59.8%); and low for ANC (36.9%) and PNC (24.5%). CONCLUSIONS: In the study facilities, the QoC for MNH services is found to be unsatisfactory, particularly for ANC and PNC. Urgent initiative needs to be taken by introducing contextualized quality monitoring tools at health facilities, along with training of the care providers and introducing a quality monitoring system.

BACKGROUND: In Bangladesh, while the infrastructure of public health facilities to provide maternal and newborn care services is adequate, services are not always available due to insufficient staffing. A human resource availability index for health facilities is needed for monitoring and advocacy. This study aimed to develop indices for measuring the availability of different types of human resources to provide round-the-clock emergency obstetric and newborn care (EmONC) service at district-level public facilities. METHODS: As part of a larger intervention study, 30 days of prospective observation of providers was done at a district hospital (DH) and a mother and child welfare centre (MCWC) in one district of Bangladesh using checklists. A scoring system was developed to create an index to quantify the availability of providers for maternal and newborn care. RESULTS: Based on the newly developed index, medical doctors in the emergency department of the DH were 100% available, but ranged from 27 to 41% availability in the obstetrics/gynecology (ob/gyn) and pediatric wards. In MCWC, the corresponding indices ranged from 32 to 36%. In the DH, the availability of nurses in the ob/gyn ward (96%) was relatively better than in the pediatric ward (65%) but that in operation theatre was only 31%. In the MCWC, the index for the presence of a paramedic or nursing aid was 82% in the ob/gyn ward and 63% in the operation theatre. However, the availability scores of facility support staff for maintenance and security were generally high (over 90%) in both facilities. CONCLUSIONS: Our newly developed index on availability of providers demonstrated huge gaps in availability of providers in evening and night shifts in most of the disciplines in the study facilities. This provider availability index is easy to create and can be used as a meaningful tool to quantify gaps in human resources by type in various types of district-level health facilities. Further studies are needed for adaptation of this tool in different types of health facilities and to assess its implication as an advocacy tool.

BACKGROUND: The capacity to demand and use research is critical for governments if they are to develop policies that are informed by evidence. Existing tools designed to assess how government officials use evidence in decision-making have significant limitations for low- and middle-income countries (LMICs); they are rarely tested in LMICs and focus only on individual capacity. This paper introduces an instrument that was developed to assess Ministry of Health (MoH) capacity to demand and use research evidence for decision-making, which was tested for reliability and validity in eight LMICs (Bangladesh, Fiji, India, Lebanon, Moldova, Pakistan, South Africa, Zambia). METHODS: Instrument development was based on a new conceptual framework that addresses individual, organisational and systems capacities, and items were drawn from existing instruments and a literature review. After initial item development and pre-testing to address face validity and item phrasing, the instrument was reduced to 54 items for further validation and item reduction. In-country study teams interviewed a systematic sample of 203 MoH officials. Exploratory factor analysis was used in addition to standard reliability and validity measures to further assess the items. RESULTS: Thirty items divided between two factors representing organisational and individual capacity constructs were identified. South Africa and Zambia demonstrated the highest level of organisational capacity to use research, whereas Pakistan and Bangladesh were the lowest two. In contrast, individual capacity was highest in Pakistan, followed by South Africa, whereas Bangladesh and Lebanon were the lowest. CONCLUSION: The framework and related instrument represent a new opportunity for MoHs to identify ways to understand and improve capacities to incorporate research evidence in decision-making, as well as to provide a basis for tracking change.

BACKGROUND: Injury is the number one public health problem in Lithuania in terms of disability adjusted life years lost. The trauma system plays an important role in injury statistics. The objective of this article is to describe and assess the performance of Lithuanian trauma sector. METHODS: The framework for assessing the performance of health systems proposed by Murray and Frenk (2000) was employed. RESULTS: The primary intention criterion--to reduce the number of trauma cases, injury related mortality and disability rates by 30% by 2010-is well defined. The Lithuanian whole-trauma sector does not substantially contribute to improving the health of the population. The legitimate expectations of the community--respect of persons in terms of dignity, autonomy, confidentiality, client orientation--do not correspond with the responsiveness of the trauma service. Financing of the trauma sector does not correspond with the magnitude of the injury problem. Lithuanian trauma service is decentralized. There is no trauma leadership in the country. There is no national policy for unintentional injury prevention and control, no specialized injury research institute, no system of trauma centres, and no Injury Surveillance System in Lithuania. There is no such specialty as Emergency Medicine as of 2009. A political and public will to reform the trauma sector is not sound. CONCLUSION: The performance of the decentralized Lithuanian trauma sector does not match with the primary intention criterion and does not correspond to the needs of people. Lithuanian trauma service has to be conceptualized and changed to inclusive.

BACKGROUND: Although a number of intermediate transport initiatives have been used in some developing countries, available evidence reveals a dearth of local knowledge on the effect of these rural informal transport mechanisms on access to maternal health care services, the cost of implementing such schemes and their scalability. This paper, attempts to provide insights into the functioning of the informal transport markets in facilitating access to maternal health care. It also demonstrates the role that higher institutions of learning can play in designing projects that can increase the utilization of maternal health services. OBJECTIVES: To explore the use of intermediate transport mechanisms to improve access to maternal health services, with emphasis on the benefits and unintended consequences of the transport scheme, as well as challenges in the implementation of the scheme. METHODS: This paper is based on the pilot phase to inform a quasi experimental study aimed at increasing access to maternal health services using demand and supply side incentives. The data collection for this paper included qualitative and quantitative methods that included focus group interviews, review of project documents and facility level data. RESULTS: There was a marked increase in attendance of antenatal, and delivery care services, with the contracted transporters playing a leading role in mobilizing mothers to attend services. The project also had economic spill-over effects to the transport providers, their families and community generally. However, some challenges were faced including difficulty in setting prices for paying transporters, and poor enforcement of existing traffic regulations. CONCLUSIONS AND IMPLICATIONS: The findings indicate that locally existing resources such as motorcycle riders, also known as "boda boda" can be used innovatively to reduce challenges caused by geographical inaccessibility and a poor transport network with resultant increases in the utilization of maternal health services. However, care must be taken to mobilize the resources needed and to ensure that there is enforcement of laws that will ensure the safety of clients and the transport providers themselves.
RESUMEN
BACKGROUND: Geographical inaccessibility, lack of transport, and financial burdens are some of the demand side constraints to maternal health services in Uganda, while supply side problems include poor quality services related to unmotivated health workers and inadequate supplies. Most public health interventions in Uganda have addressed only selected supply side issues, and universities have focused their efforts on providing maternal services at tertiary hospitals. To demonstrate how reforms at Makerere University College of Health Sciences (MakCHS) can lead to making systemic changes that can improve maternal health services, a demand and supply side strategy was developed by working with local communities and national stakeholders. METHODS: This quasi-experimental trial is conducted in two districts in Eastern Uganda. The supply side component includes health worker refresher training and additions of minimal drugs and supplies, whereas the demand side component involves vouchers given to pregnant women for motorcycle transport and the payment to service providers for antenatal, delivery, and postnatal care. The trial is ongoing, but early analysis from routine health information systems on the number of services used is presented. RESULTS: Motorcyclists in the community organized themselves to accept vouchers in exchange for transport for antenatal care, deliveries and postnatal care, and have become actively involved in ensuring that women obtain care. Increases in antenatal, delivery, and postnatal care were demonstrated, with the number of safe deliveries in the intervention area immediately jumping from <200 deliveries/month to over 500 deliveries/month in the intervention arm. Voucher revenues have been used to obtain needed supplies to improve quality and to pay health workers, ensuring their availability at a time when workloads are increasing. CONCLUSIONS: Transport and service vouchers appear to be a viable strategy for rapidly increasing maternal care. MakCHS can design strategies together with stakeholders using a learning-by-doing approach to take advantage of community resources.
RESUMEN
BACKGROUND: Despite recent achievement in economic progress in India, the fruit of development has failed to secure a better nutritional status among all children of the country. Growing evidence suggest there exists a socio-economic gradient of childhood malnutrition in India. The present paper is an attempt to measure the extent of socio-economic inequality in chronic childhood malnutrition across major states of India and to realize the role of household socio-economic status (SES) as the contextual determinant of nutritional status of children. METHODS: Using National Family Health Survey-3 data, an attempt is made to estimate socio-economic inequality in childhood stunting at the state level through Concentration Index (CI). Multi-level models; random-coefficient and random-slope are employed to study the impact of SES on long-term nutritional status among children, keeping in view the hierarchical nature of data. MAIN FINDINGS: Across the states, a disproportionate burden of stunting is observed among the children from poor SES, more so in urban areas. The state having lower prevalence of chronic childhood malnutrition shows much higher burden among the poor. Though a negative correlation (r = -0.603, p < .001) is established between Net State Domestic Product (NSDP) and CI values for stunting; the development indicator is not always linearly correlated with intra-state inequality in malnutrition prevalence. Results from multi-level models however show children from highest SES quintile posses 50 percent better nutritional status than those from the poorest quintile. CONCLUSION: In spite of the declining trend of chronic childhood malnutrition in India, the concerns remain for its disproportionate burden on the poor. The socio-economic gradient of long-term nutritional status among children needs special focus, more so in the states where chronic malnutrition among children apparently demonstrates a lower prevalence. The paper calls for state specific policies which are designed and implemented on a priority basis, keeping in view the nature of inequality in childhood malnutrition in the country and its differential characteristics across the states.
RESUMEN
BACKGROUND: Civil registration and vital statistics (CRVS) systems lay the foundation for good governance by increasing the effectiveness and delivery of public services, providing vital statistics for the planning and monitoring of national development, and protecting fundamental human rights. Birth registration provides legal rights and facilitates access to essential public services such as health care and education. However, more than 110 low- and middle-income countries (LMICs) have deficient CRVS systems, and national birth registration rates continue to fall behind childhood immunization rates. Using Demographic and Health Survey (DHS) and Multiple Indicator Cluster Survey (MICS) data in 72 LMICs, the objectives are to (a) explore the status of birth registration, routine childhood immunization, and maternal health services utilization; (b) analyze indicators of birth registration, routine childhood immunization, and maternal health services utilization; and (c) identify missed opportunities for strengthening birth registration systems in countries with strong childhood immunization and maternal health services by measuring the absolute differences between the birth registration rates and these childhood and maternal health service indicators. METHODS: We constructed a database using DHS and MICS data from 2000 to 2017, containing information on birth registration, immunization coverage, and maternal health service indicators. Seventy-three countries including 34 low-income countries and 38 lower middle-income countries were included in this exploratory analysis. RESULTS: Among the 14 countries with disparity between birth registration and BCG vaccination of more than 50%, nine were from sub-Saharan Africa (Tanzania, Uganda, Gambia, Mozambique, Djibouti, Eswatini, Zambia, Democratic Republic of Congo, Ghana), two were from South Asia (Bangladesh, Nepal), one from East Asia and the Pacific (Vanuatu) one from Latin America and the Caribbean (Bolivia), and one from Europe and Central Asia (Moldova). Countries with a 50% or above absolute difference between birth registration and antenatal care coverage include Democratic Republic of Congo, Gambia, Mozambique, Nepal, Tanzania, and Uganda, in low-income countries. Among lower middle-income countries, this includes Eswatini, Ghana, Moldova, Timor-Leste, Vanuatu, and Zambia. Countries with a 50% or above absolute difference between birth registration and facility delivery care coverage include Democratic Republic of Congo, Djibouti, Moldova, and Zambia. CONCLUSION: The gap between birth registration and immunization coverage in low- and lower middle-income countries suggests the potential for leveraging immunization programs to increase birth registration rates. Engaging health providers during the antenatal, delivery, and postpartum periods to increase birth registration may be a useful strategy in countries with access to skilled providers.

AIMS: This study aims to explore the spectrum of renal disease in HIV-infected patients, identify clinical predictors of HIV-associated nephropathy (HIVAN), and investigate the performance of renal biopsy in HIV-infected patients. METHOD: Of 263 HIV-infected patients with renal disease evaluated between 1995 and 2004, 152 had a renal biopsy, while 111 had not. A group comparison was performed. RESULTS: The leading biopsy diagnoses were HIVAN (35%), noncollapsing focal segmental glomerulosclerosis (22%), and acute interstitial nephritis (7.9%), amongst over a dozen others. There was a trend of decreasing yearly incidence of HIVAN diagnoses, paralleling the use of antiretroviral therapy. By multivariate logistic regression, CD4 counts >200 cells/mm(3) and higher estimated glomerular filtration rate were strong negative predictors of HIVAN. HIVAN patients were more likely to require dialysis (p < 0.0001) and had worse overall survival (p = 0.02). Younger age and lower estimated glomerular filtration rate were significant predictors of renal biopsy in multivariate regression analysis. More biopsied patients progressed to dialysis (51 vs. 25%, p = 0.001) and death (15 vs. 5.4%, p = 0.001), despite more frequent corticosteroid treatment (29 vs. 3.6%, p = 0.001). CONCLUSION: These findings may reflect more severe acute and/or chronic disease at the time of biopsy and suggests that earlier renal biopsy may be warranted in HIV-infected patients, especially in light of the changing spectrum of renal disease in this group.

People in poor countries tend to have less access to health services than those in better-off countries, and within countries, the poor have less access to health services. This article documents disparities in access to health services in low- and middle-income countries (LMICs), using a framework incorporating quality, geographic accessibility, availability, financial accessibility, and acceptability of services. Whereas the poor in LMICs are consistently at a disadvantage in each of the dimensions of access and their determinants, this need not be the case. Many different approaches are shown to improve access to the poor, using targeted or universal approaches, engaging government, nongovernmental, or commercial organizations, and pursuing a wide variety of strategies to finance and organize services. Key ingredients of success include concerted efforts to reach the poor, engaging communities and disadvantaged people, encouraging local adaptation, and careful monitoring of effects on the poor. Yet governments in LMICs rarely focus on the poor in their policies or the implementation or monitoring of health service strategies. There are also new innovations in financing, delivery, and regulation of health services that hold promise for improving access to the poor, such as the use of health equity funds, conditional cash transfers, and coproduction and regulation of health services. The challenge remains to find ways to ensure that vulnerable populations have a say in how strategies are developed, implemented, and accounted for in ways that demonstrate improvements in access by the poor.

BACKGROUND: While some studies have reported that IgA nephropathy has a relatively benign clinical course in children, others have shown that renal outcomes of paediatric patients with IgA nephropathy followed into adulthood are similar to those of patients diagnosed as adults. Some of this variability may be related to differences in histologic severity of cohorts of patients diagnosed as children versus adults. METHODS: We retrospectively examined correlations between renal biopsy findings, clinical features at presentation and renal survival in 99 children and adolescents (Asunto(s)

RESUMEN
Phytochemical investigation on the aerial parts of Lyonia ovalifolia (Wall.) Drude led to the isolation of three new iridoids, lyonofolin A (1), lyonofolin B (2), and lyonofolin C (3), and a known iridoid, gelsemiol (4). Structures of compounds 1-4 were determined by extensive spectroscopic analyses, including EI-MS, HREI-MS, UV, IR, and 1D- and 2D-NMR (HMBC, HSQC, COSY, NOESY) spectroscopic methods. The effect of insulin secretion of compounds 1, 2, and 4 were evaluated in mice pancreatic islets cellular model. This insulin secretory assay demonstrated that compound 2 potentiates glucose-induced insulin secretion, and thus can serve as a new insulin secretagogue for the treatment of diabetes. The newly isolated compounds were further evaluated against normal 3â¯T3 cell lines for cytotoxicity, where they did not show any cytotoxicity.

Polyomavirus virus nephropathy (PVN) is an important cause of renal allograft dysfunction. The risk factors for the development of PVN have not been completely elucidated. We investigated the hypothesis that ureteral trauma caused by placement of indwelling stents is an independent risk factor for PVN. Twenty cases of PVN were compared with 46 controls. Logistic regression was used to calculate odds ratios and to construct multivariate models. A total of 75% of cases and 35% of controls had stents placed during renal transplantation. In both univariate and multivariate logistic regression analyses adjusting for age, gender, deceased donor transplant, delayed graft function, tacrolimus and exposure to antibodies, the placement of a ureteral stent at the time of kidney transplantation was found to have a statistically significant association with developing PVN. Our findings reveal that the presence of a ureteral stent is associated with an increase in the risk of PVN.

To determine the value of human immunodeficiency virus type 1 (HIV-1) RNA level in distinguishing HIV-associated nephropathy from non-HIV-associated nephropathy renal pathological conditions, we retrospectively compared renal histopathological findings for 86 HIV-infected patients according to HIV-1 RNA levels. We found that HIV-associated nephropathy was unlikely among patients with HIV-1 RNA levels <400 copies/mL. Hypertensive vascular disease surpassed HIV-associated nephropathy as the most common renal pathological finding among the entire cohort. HIV-1 RNA level did not correlate with renal survival.

Considering the high burden of injuries, the Health Authority-Abu Dhabi developed a draft electronic and paper-based injury and poisoning notification system (IPNS) to generate better data on the nature and severity of injuries. The pilot testing and evaluation of IPNS was conducted with the specific objectives to (1) identify the characteristics of injury cases, (2) explore potential risk factors, (3) illustrate the nature and type of data, and (4) the working mechanism of data collection. Data were collected from selected hospitals on patient demographics, injury information and clinical assessment. Descriptive, bivariate and multivariate analyses were conducted. Of 4226 injury cases, nearly three-fourths were male, majority were non-UAE nationals, and the mean age was 21.9. Multivariate findings suggested that compared to UAE nationals, non-UAE nationals were 27% more likely to experience fatal, severe or moderate injuries (p = 0.01). Individuals with health insurance were 31% less likely to suffer a fatal, severe or moderate injury compared to those having no health insurance (p < 0.001). This is the first systematically standardised collection of injury data across three facilities in Abu Dhabi, and provides initial information on characteristics and injury risk factors that will help identify the need for evidence-based intervention for injury prevention and control.

Anti-neutrophil cytoplasmic antibodies (ANCA) play an important role in the pathogenesis of ANCA-associated vasculitis. The lack of ANCA antibodies may indicate a variation in clinical presentation and outcomes of this disease. We identified 74 adult patients between 1995 and 2009 with the diagnosis of pauci-immune glomerulonephritis. Demographics, histological features, and treatment outcomes were compared between ANCA-positive and ANCA-negative patients. These factors were correlated with renal function at presentation and follow-up. Of the 74 patients, 57 were ANCA-positive, and 17 were ANCA-negative. Demographics and mean Birmingham Vasculitis Activity Score were similar between ANCA-negative and ANCA-positive patients at presentation. Renal function was significantly worse at presentation in the ANCA-negative patients (eGFR 16.59 vs. 31.89 ml/min/1.73 m(2), p = 0.03). Patients in the ANCA-negative group had a significantly higher interstitial fibrosis score compared to the ANCA-positive group (2.1 vs.1.6, p = 0.04). The median time to remission was shorter in the ANCA-negative patients (51 vs. 78 days, p = 0.01). Long-term renal function and 1-year patient and renal survival were similar between ANCA-negative and ANCA-positive patients. Baseline eGFR, percentage of normal glomeruli, glomerular sclerosis, and tubulointerstitial scarring predicted eGFR at 1 year in both groups similarly. This is the first historical review of American patients with pauci-immune glomerulonephritis, comparing patients with ANCA-negative and ANCA-positive serology. Although ANCA-negative patients present with lower eGFR and more interstitial fibrosis, 1-year and long-term outcomes in both groups are similar.

BACKGROUND: Informally trained village doctors supply the majority of healthcare services to the rural poor in many developing countries. This study describes the demographic and socio-economic differences between medical representatives (MRs) and village doctors in rural Bangladesh, and explores the nature of their interactions. METHODS: This study was conducted in Chakaria, a rural sub-district of Bangladesh. Focus group discussions and in-depth interviews were conducted, along with a quantitative survey to understand practice perceptions. Data analysis was performed using grounded theory and bivariate statistical tests. RESULTS: We surveyed 43 MRs and 83 village doctors through 22 focus group discussions and 33 in-depth interviews. MRs have a higher average per capita monthly expenditure compared to village doctors. MRs are better educated with 98% having bachelor's degrees whereas 84% of village doctors have twelfth grade education or less (p<0.001). MRs are the principal information source about new medications for the village doctors. Furthermore, incentives offered by MRs and credit availability influence the prescription practices of village doctors. CONCLUSIONS: MRs being the key player in providing information about drugs to village doctors might influence their prescription practices. Improvements in the quality of healthcare delivered to the rural poor in informal provider-based health markets require stricter regulations and educational initiatives for providers and MRs.

OBJECTIVE: Road traffic injuries pose a significant threat to the Egyptian population. Recent estimates revealed that Egypt experiences 42 road traffic deaths per 100,000 population (1.8% of all deaths in the country), which is the highest death rate in the region. More than half of the road traffic crashes that resulted in injuries occurred on the country's highways. Despite the significance of this public health problem, very little risk factor information currently exists. The overall goal of this paper is to understand the burden of speeding and the level of seatbelt and child restraint use on a highway (Cairo Ring Road) and two urban roads crossing Alexandria city (Kornish and Gamal Abd-Elnaser roads). METHODS: Two rounds of seatbelt and child restraint observational studies and one round of speed observational study were carried out between 2011 and 2012. RESULTS: Findings revealed that seatbelt use among drivers and front seat passengers were low for all three sites (range: 11.1% to 19.8% for drivers; 2.9% to 4.0% for front seat passengers). Similarly, child restraint use in cars with children was very low ranging from 1.1% to 3.9% on all three roads. All three roads experienced a high percentage of vehicles driving above the speed limit (39.4% on Kornish Road, 22.6% on Cairo Ring Road, 11.8% on Gamal Abd-Elnaser Road), with the majority of these vehicles driving 1 to 10 kilometer above the speed limit. CONCLUSION: Future interventions need to focus on enhancing enforcement of speed and seatbelt wearing, closing gaps in legislation, and standardizing existing data systems to help inform good road safety policies.

INTRODUCTION: Continuous evaluation of child survival is needed in sub-Saharan Africa where HIV prevalence among women of reproductive age continues to be high. We examined mortality levels and trends over a period of â¼20 years among HIV-unexposed and -exposed children in Blantyre, Malawi. METHODS: Data from 5 prospective cohort studies conducted at a single research site from 1989 to 2009 were analyzed. In these studies, children born to HIV-infected and -uninfected mothers were enrolled at birth and followed longitudinally for at least 2 years. Information on sociodemographic, HIV infection status, survival, and associated risk factors was collected in all studies. Mortality rates were estimated using birth-cohort analyses stratified by maternal and infant HIV status. Multivariate Cox regression models were used to determine risk factors associated with mortality. RESULTS: The analysis included 8286 children. From 1989 to 1995, overall mortality rates (per 100 person-years) in these clinic-based cohorts remained comparable among HIV-uninfected children born to HIV-uninfected mothers (range 3.3-6.9) or to HIV-infected mothers (range 2.5-7.5). From 1989 to 2009, overall mortality remained high among all children born to HIV-infected mothers (range 6.3-19.3) and among children who themselves became infected (range 15.6-57.4, 1994-2009). Only lower birth weight was consistently and significantly (P < 0.05) associated with higher child mortality. CONCLUSIONS: HIV infection among mothers and children contributed to high levels of child mortality in the African setting in the pretreatment era. In addition to services that prevent mother-to-child transmission of HIV, other programs are needed to improve child survival by lowering HIV-unrelated mortality through innovative interventions that strengthen health infrastructure.
