Abstract
BACKGROUND There is a lack of reliable data in developing countries to inform policy and optimise resource allocation. Health and socio-demographic surveillance sites (HDSS) have the potential to address this gap. Mortality levels and trends have previously been documented in rural South Africa. However, complex space-time clustering of mortality, determinants, and their impact has not been fully examined. OBJECTIVES To integrate advanced methods enhance the understanding of the dynamics of mortality in space-time, to identify mortality risk factors and population attributable impact, to relate disparities in risk factor distributions to spatial mortality risk, and thus, to improve policy planning and resource allocation. METHODS Agincourt HDSS supplied data for the period 1992-2008. Advanced spatial techniques were used to identify significant age-specific mortality 'hotspots' in space-time. Multivariable Bayesian models were used to assess the effects of the most significant covariates on mortality. Disparities in risk factor profiles in identified hotspots were assessed. RESULTS Increasing HIV-related mortality and a subsequent decrease possibly attributable to antiretroviral therapy introduction are evident in this rural population. Distinct space-time clustering and variation (even in a small geographic area) of mortality were observed. Several known and novel risk factors were identified, and population impact was quantified. Significant differences in the risk factor profiles of the identified 'hotspots' included ethnicity; maternal, partner, and household deaths; household head demographics; migrancy; education; and poverty. CONCLUSIONS A complex interaction of highly attributable multilevel factors continues to demonstrate differential space-time influences on mortality risk (especially for HIV). High-risk households and villages displayed differential risk factor profiles. This integrated approach could prove valuable to decision makers. Tailored interventions for specific child and adult high-risk mortality areas are needed, such as preventing vertical transmission, ensuring maternal survival, and improving water and sanitation infrastructure. This framework can be applied in other settings within the region.

Abstract
BACKGROUND The efficacy of preventive zinc supplementation against diarrhea and respiratory illness may depend on simultaneous supplementation with other micronutrients. We aimed to assess the effect of supplementation with zinc and multiple micronutrients on diarrhea and other causes of non-malarial morbidity. METHODS AND FINDINGS Rural Tanzanian children (n = 612) aged 6-60 months and with height-for-age z-score < -1.5 SD were randomized to daily supplementation with zinc (10 mg) alone, multi-nutrients without zinc, multi-nutrients with zinc, or placebo. Children were followed for an average of 45 weeks. During follow-up, we recorded morbidity episodes. We found no evidence that concurrent supplementation with multi-nutrients influenced the magnitude of the effect of zinc on rates of diarrhea, respiratory illness, fever without localizing signs, or other illness (guardian-reported illness with symptoms involving skin, ears, eyes and abscesses, but excluding trauma or burns). Zinc supplementation reduced the hazard rate of diarrhea by 24% (4%-40%). By contrast, multi-nutrients seemed to increase this rate (HR; 95% CI: 1.19; 0.94-1.50), particularly in children with asymptomatic Giardia infection at baseline (2.03; 1.24-3.32). Zinc also protected against episodes of fever without localizing signs (0.75; 0.57-0.96), but we found no evidence that it reduced the overall number of clinic visits. CONCLUSIONS We found no evidence that the efficacy of zinc supplements in reducing diarrhea rates is enhanced by concurrent supplementation with other micronutrients. By reducing rates of fever without localizing signs, supplementation with zinc may reduce inappropriate drug use with anti-malarial medications and antibiotics.

Abstract
Background The impact of toxigenic Clostridium difficile colonization (tCDC) in hospitalized patients is not clear. Aim To study the significance of tCDC in hospitalized patients. Methods A prospective study in the medical wards of a regional hospital was performed from January to June 2011. Fecal samples collected from patients at the time of admission were tested for tcdB by real-time polymerase chain reaction (PCR) and cultured for C. difficile. The patients were followed up weekly or when they developed diarrhea during hospitalization. If C. difficile was isolated, tcdA and tcdB would be tested by multiplex PCR. The primary outcome was the development of C. difficile-associated diarrhea (CDAD). Findings Of 168 patients enrolled, females predominated (87, 51.8%), and the mean patient age was 75.4 years old. Approximately 70% of the patients were nursing home residents, and one third had a recent hospitalization within the prior three months. Twenty-eight (16.7%) patients had tCDC, including 16 (9.5%) patients with tCDC at the time of admission and 12 (7.2%) with tCDC during the follow-up period. With regard to the medications taken during hospitalization, the patients were more likely to have tCDC if they had received more than one class of antibiotics than if they had received monotherapy (odds ratio [OR] 6.67, 95% confidence interval [CI] 1.41–31.56, P = 0.01), particularly if they received a glycopeptide in combination with a cephalosporin or penicillin or a cephalosporin and a carbapenem. More patients with tCDC developed CDAD than those without tCDC (17.9%, 5/28 vs. 1.4%, 2/140, P = 0.002). Overall 7 (4.2%) of the 168 patients developed CDAD, and crude mortality rate of those with and without tCDC was similar (21.4%, 6/28 vs. 19.4%, 27/140, P = 0.79). Conclusion Recent use of glycopeptides and β-lactam antibiotics is associated with toxigenic C. difficile colonization, which is a risk factor for developing C. difficile-associated diarrhea.

Abstract
BACKGROUND In developing countries, diarrhoea causes around two million child deaths annually. Zinc supplementation during acute diarrhoea is currently recommended by the World Health Organization and UNICEF. OBJECTIVES To evaluate oral zinc supplementation for treating children with acute or persistent diarrhoea. SEARCH METHODS In February 2012, we searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL (The Cochrane Library 2011, Issue 11), MEDLINE, EMBASE, LILACS, CINAHL, mRCT, and reference lists. We also contacted researchers. SELECTION CRITERIA Randomized controlled trials comparing oral zinc supplementation with placebo in children aged one month to five years with acute or persistent diarrhoea, including dysentery. DATA COLLECTION AND ANALYSIS Both authors assessed trial eligibility and risk of bias, extracted and analysed data, and drafted the review. Diarrhoea duration and severity were the primary outcomes. We summarized dichotomous outcomes using risk ratios (RR) and continuous outcomes using mean differences (MD) with 95% confidence intervals (CI). Where appropriate, we combined data in meta-analyses (using the fixed- or random-effects model) and assessed heterogeneity.The quality of evidence has been assessed using the GRADE methods MAIN RESULTS Twenty-four trials, enrolling 9128 children, met our inclusion criteria. The majority of the data is from Asia, from countries at high risk of zinc deficiency, and may not be applicable elsewhere.Acute diarrhoeaThere is currently not enough evidence from well conducted randomized controlled trials to be able to say whether zinc supplementation during acute diarrhoea reduces death or hospitalization (very low quality evidence).In children aged greater than six months with acute diarrhoea, zinc supplementation may shorten the duration of diarrhoea by around 10 hours (MD -10.44 hours, 95% CI -21.13 to 0.25; 2091 children, five trials, low quality evidence), and probably reduces the number of children whose diarrhoea persists until day seven (RR 0.73, 95% CI 0.61 to 0.88; 3865 children, six trials, moderate quality evidence). In children with signs of moderate malnutrition the effect appears greater, reducing the duration of diarrhoea by around 27 hours (MD -26.98 hours, 95% CI -14.62 to -39.34; 336 children, three trials, high quality evidence).Conversely, In children aged less than six months, the available evidence suggests zinc supplementation may have no effect on mean diarrhoea duration (MD 5.23 hours, 95% CI -4.00 to 14.45; 1334 children, two trials, low quality evidence), and may even increase the proportion of children whose diarrhoea persists until day seven (RR 1.24, 95% CI 0.99 to 1.54; 1074 children, one trial, moderate quality evidence).No trials reported serious adverse events, but zinc supplementation during acute diarrhoea causes vomiting in both age groups (RR 1.59, 95% 1.27 to 1.99; 5189 children, 10 trials, high quality evidence).Persistent diarrhoeaIn children with persistent diarrhoea, zinc supplementation probably shortens the duration of diarrhoea by around 16 hours (MD -15.84 hours, 95% CI -25.43 to -6.24; 529 children, five trials, moderate quality evidence). AUTHORS' CONCLUSIONS In areas where the prevalence of zinc deficiency or the prevalence of moderate malnutrition is high, zinc may be of benefit in children aged six months or more.The current evidence does not support the use of zinc supplementation in children below six months of age.

Abstract
BACKGROUND Information about the distribution of causes of and time trends for child mortality should be periodically updated. We report the latest estimates of causes of child mortality in 2010 with time trends since 2000. METHODS Updated total numbers of deaths in children aged 0-27 days and 1-59 months were applied to the corresponding country-specific distribution of deaths by cause. We did the following to derive the number of deaths in children aged 1-59 months: we used vital registration data for countries with an adequate vital registration system; we applied a multinomial logistic regression model to vital registration data for low-mortality countries without adequate vital registration; we used a similar multinomial logistic regression with verbal autopsy data for high-mortality countries; for India and China, we developed national models. We aggregated country results to generate regional and global estimates. FINDINGS Of 7·6 million deaths in children younger than 5 years in 2010, 64·0% (4·879 million) were attributable to infectious causes and 40·3% (3·072 million) occurred in neonates. Preterm birth complications (14·1%; 1·078 million, uncertainty range [UR] 0·916-1·325), intrapartum-related complications (9·4%; 0·717 million, 0·610-0·876), and sepsis or meningitis (5·2%; 0·393 million, 0·252-0·552) were the leading causes of neonatal death. In older children, pneumonia (14·1%; 1·071 million, 0·977-1·176), diarrhoea (9·9%; 0·751 million, 0·538-1·031), and malaria (7·4%; 0·564 million, 0·432-0·709) claimed the most lives. Despite tremendous efforts to identify relevant data, the causes of only 2·7% (0·205 million) of deaths in children younger than 5 years were medically certified in 2010. Between 2000 and 2010, the global burden of deaths in children younger than 5 years decreased by 2 million, of which pneumonia, measles, and diarrhoea contributed the most to the overall reduction (0·451 million [0·339-0·547], 0·363 million [0·283-0·419], and 0·359 million [0·215-0·476], respectively). However, only tetanus, measles, AIDS, and malaria (in Africa) decreased at an annual rate sufficient to attain the Millennium Development Goal 4. INTERPRETATION Child survival strategies should direct resources toward the leading causes of child mortality, with attention focusing on infectious and neonatal causes. More rapid decreases from 2010-15 will need accelerated reduction for the most common causes of death, notably pneumonia and preterm birth complications. Continued efforts to gather high-quality data and enhance estimation methods are essential for the improvement of future estimates. FUNDING The Bill & Melinda Gates Foundation.

Abstract
Background Severe acute malnutrition (SAM) accounts for two million deaths worldwide annually. In those hospitalised with SAM, concomitant infections and diarrhoea are frequent complications resulting in adverse outcome. We examined the clinical and laboratory features on admission and outcome of children with SAM and diarrhoea at a Kenyan district hospital. Methods A 4-year prospective descriptive study involving 1,206 children aged 6 months to 12 years, hospitalized with SAM and managed in accordance with WHO guidelines. Data on clinical features, haematological, biochemical and microbiological findings for children with diarrhoea (≥3 watery stools/day) were systematically collected and analyzed to identify risk factors associated with poor outcome. Results At admission 592 children (49%) had diarrhoea of which 122 (21%) died compared to 72/614 (12%) deaths in those without diarrhoea at admission (Χ2 = 17.6 p<0.001). A further 187 (16%) children developed diarrhoea after 48 hours of admission and 33 died (18%). Any diarrhoea during admission resulted in a significantly higher mortality 161/852 (19%) than those uncomplicated by diarrhoea 33/351 (9%) (Χ2 = 16.6 p<0.001). Features associated with a fatal outcome in children presenting with diarrhoea included bacteraemia, hyponatraemia, low mid-upper arm circumference <10 cm, hypoxia, hypokalaemia and oedema. Bacteraemia had the highest risk of death (adjusted OR 6.1; 95% C.I 2.3, 16.3 p<0.001); and complicated 24 (20%) of fatalities. Positive HIV antibody status was more frequent in cases with diarrhoea at admission (23%) than those without (15%, Χ2 = 12.0 p = 0.001) but did not increase the risk of death in diarrhoea cases. Conclusion Children with SAM complicated by diarrhoea had a higher risk of death than those who did not have diarrhoea during their hospital stay. Further operational and clinical research is needed to reduce mortality in children with SAM in the given setting.

Abstract
Background Diarrhea remains one of the leading causes of morbidity and mortality among children under 5 years of age, but in many low and middle-income countries where vital registration data are lacking, updated estimates with regard to the proportion of deaths attributable to diarrhea are needed. Methods We conducted a systematic literature review to identify studies reporting diarrhea proportionate mortality for children 1–59 mo of age published between 1980 and 2009. Using the published proportionate mortality estimates and country level covariates we constructed a logistic regression model to estimate country and regional level proportionate mortality and estimated uncertainty bounds using Monte-Carlo simulations. Findings We identified more than 90 verbal autopsy studies from around the world to contribute data to a single-cause model. We estimated diarrhea proportionate mortality for 84 countries in 6 regions and found diarrhea to account for between 10.0% of deaths in the Americas to 31.3% of deaths in the South-east Asian region. Discussion Diarrhea remains a leading cause of death for children 1–59 mo of age. Published literature can be used to create a single-cause mortality disease model to estimate mortality for countries lacking vital registration data.

Abstract
Rotavirus disease is the leading cause of childhood morbidity and mortality related to diarrhea in Latin America and the Caribbean (LAC), where an estimated 8,000 deaths related to rotavirus diarrhea occur annually among children aged <5 years. After two safe and effective rotavirus vaccines became available, the World Health Organization (WHO) in 2007 recommended inclusion of rotavirus vaccine in the immunization programs of Europe and the Americas, and in 2009 expanded the recommendation to all infants aged <32 weeks worldwide. This report describes progress in the introduction of rotavirus vaccine in LAC, where it was first introduced in 2006 in Brazil, El Salvador, Mexico, Nicaragua, Panama, and Venezuela; by January 2011, it was included in the national immunization schedules of 14 countries in LAC. Estimated national rotavirus vaccine coverage (2 doses of the monovalent vaccine or 3 doses of the pentavalent vaccine) among children aged <1 year in 2010 ranged from 49% to 98% (median: 89%) in the 11 LAC countries with vaccine introduction before 2010. Of the 14 countries that had introduced rotavirus vaccine into their national immunization programs, 13 participate in a hospital-based rotavirus surveillance network. Data from some countries in this network and from other monitoring efforts in LAC countries have shown declines in hospitalizations and deaths related to severe diarrhea after rotavirus vaccine introduction. The rapid introduction of rotavirus vaccine in LAC demonstrates the benefits of the early commitment of national decision makers to introduce these vaccines in low-income and middle-income countries at the same time as in high-income countries.

Abstract
AIM To evaluate the clinical and laboratory predictors of death in hospitalized under-five children with diarrhoea. METHODS This is a prospective cohort study carried out in the Special Care Ward (SCW) of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B), Dhaka, Bangladesh. All admitted diarrhoeal children of both sexes, aged 0-59 months, from September 2007 through December 2007 were enrolled. We compared and analysed factors among diarrhoeal children who died (n = 29) with those who survived (n = 229). RESULTS In logistic regression analysis, after adjusting for potential confounders (infusion of intravenous fluid and immature PMN), absent peripheral pulse even after complete rehydration (OR 10.9, 95% CI 2.1-56.8; p < 0.01), severe malnutrition (OR 7.9, 95% CI 1.8-34.8; p < 0.01), hypoxaemia (OR 8.5, 95% CI 1.0-75.0; p = 0.05), radiological lobar pneumonia (OR 17.8, 95% CI 3.7-84.5; p < 0.01) and hypernatraemia (OR 15.8, 95% CI 3.0-81.8; p < 0.01) were independently associated with deaths among diarrhoeal children admitted to SCW. CONCLUSIONS Thus, the absence of peripheral pulses even after full rehydration, severe malnutrition, hypoxaemia, lobar pneumonia and hypernatraemia are independent predictors of death among the under-five children with diarrhoea admitted to critical care ward of a resource-limited setting in Bangladesh.

METHODS Hospital length of stay (LOS) and deaths were abstracted from a random sample of 1294 clinical records completed at seven of the 14 participating hospitals before the intervention (2003) and 1505 records completed after two years of intervention implementation ("post-intervention"; 2006). Disability-adjusted life years (DALYs) were derived from outcome data. Hospitalization costs were calculated based on hospital and Ministry of Health records and private sector data. Intervention costs came from project accounting records. Decision-tree analysis was used to calculate incremental cost-effectiveness. RESULTS Average LOS decreased from 3.87 and 4.23 days pre-intervention to 3.55 and 3.94 days post-intervention for diarrhea (P = 0.078) and pneumonia (P = 0.055), respectively. Case fatalities decreased from 45/10 000 and 34/10 000 pre-intervention to 30/10 000 and 27/10 000 post-intervention for diarrhea (P = 0.062) and pneumonia (P = 0.37), respectively. Average total hospitalization and antibiotic costs for both diagnoses were US$ 451 (95% credibility interval [CI]: US$ 419-US$ 482) pre-intervention and US$ 437 (95% CI: US$ 402-US$ 464) post-intervention. The intervention was cost-saving in terms of DALYs (95% CI: -US$ 522- US$ 32 per DALY averted) and cost US$ 21 per hospital day averted (95% CI: -US$ 45- US$ 204). CONCLUSIONS After two years of intervention implementation, LOS and deaths for diarrhea decreased, along with LOS for pneumonia, with no increase in hospitalization costs. If these changes were entirely attributable to the intervention, it would be cost-saving.

Abstract
Medical files of children with severe malnutrition admitted at New Halfa hospital, Sudan during 2007-2009 were reviewed. A total of 1097 children (54.9%, 602 male) with severe malnutrition were admitted during the three year period. Oedematous severe malnutrition was found in 179 (16.3%) children. Of these 1097, 796 (72.6%) patients with severe malnutrition were children <2 years old. Out of these 1097 children, 780 (71.1%) and 112 (10.2%) had diarrhoea and malaria, respectively. Sixty-one (5.5%) of these children died, 237 (21.6%) discharged against medical advice and 799 (72.8%) were discharged. Of the 61 children who died 11 (18.0%) had septicaemia following diarrhoea and respiratory tract infections. The case fatality rate was not different with sex or with presence/absence of oedema.

Abstract
INTRODUCTION Mortality of children with Severe Acute Malnutrition (SAM) in inpatient set-ups in sub-Saharan Africa still remains unacceptably high. We investigated the prevalence and effect of diarrhea and HIV infection on inpatient treatment outcome of children with complicated SAM receiving treatment in inpatient units. METHOD A cohort of 430 children aged 6-59 months old with complicated SAM admitted to Zambia University Teaching Hospital's stabilization centre from August to December 2009 were followed. Data on nutritional status, socio-demographic factors, and admission medical conditions were collected up on enrollment. T-test and chi-square tests were used to compare difference in mean or percentage values. Logistic regression was used to assess risk of mortality by admission characteristics. RESULTS Majority, 55.3% (238/430) were boys. The median age of the cohort was 17 months (inter-quartile range, IQR 12-22). Among the children, 68.9% (295/428) had edema at admission. The majority of the children, 67.3% (261/388), presented with diarrhea; 38.9% (162/420) tested HIV positive; and 40.5% (174/430) of the children died. The median Length of stay of the cohort was 9 days (IQR, 5-14 days); 30.6% (53/173) of the death occurred within 48 hours of admission. Children with diarrhea on admission had two and half times higher odds of mortality than those without diarrhea; Adjusted OR = 2.5 (95% CI 1.50-4.09, P < 0.001). The odds of mortality for children with HIV infection was higher than children without HIV infection; Adjusted OR = 1.6 (95% CI 0.99-2.48 P = 0.5). CONCLUSION Diarrhea is a major cause of complication in children with severe acute malnutrition. Under the current standard management approach, diarrhea in children with SAM was found to increase their odds of death substantially irrespective of other factors.

Abstract
INTRODUCTION In Sub-Saharan Africa (SSA) sound planning is required as interest increases in the decentralization of healthcare financing and the implementation of a sector-wide approach to health care. For this, improved knowledge of national morbidity and mortality is essential. Data from remote areas of SSA are needed to ensure that public health priority-setting and actions reflect the situation in all regions, not just those easily accessed and readily researched. In order to understand the causes, circumstances and changes over time of death in a remote and underserved region, this study sought information on all deaths in a district hospital over a 17 year period. METHODS The study design was a retrospective review of the hospital records (in registers) of all patients hospitalized in Kolofata District Hospital, a rural public hospital in the Far North Region of Cameroon, 1 January 1993 to 31 December 2009. A line listing was extracted of all 1281 inpatient deaths, and this included dates of admission and death; patient name, address, sex and ethnic group; presenting complaint; duration of symptoms; summary of physical examination; and the diagnosis presumed to be the cause of death. RESULTS Children under the age of 15 years and males comprised the majority of deaths (63.9% and 56.0%, respectively). Causes of death were related to the seasons. Infectious diseases including acute lower respiratory tract infection, malaria and diarrhoeal diseases were the leading causes of death; AIDS caused most adult deaths. A total of 67% of patients presented within 1 week of symptom onset, and 56.8% of deaths occurred on or before the day after admission. Deaths due to AIDS, malaria and complications of pregnancy increased over time. Among Kolofata District residents, death from vaccine-preventable measles and neonatal tetanus were rare, particularly in the later study years. The proportion of deaths attributed to non-communicable diseases did not increase in the 17 year period. CONCLUSIONS To reduce mortality in this world region, priority should be given to the prevention and management of lower respiratory tract infections, malaria, diarrhoeal diseases, AIDS, and the complications of pregnancy. The planning of health resources and activities should take into account seasonal variations in the causes of death. Improvements to emergency services and community education that emphasises the need for earlier presentation when ill should reduce deaths that occur soon after hospital admission. Death due to measles and neonatal tetanus has become rare, a reflection of the effectiveness in this area of the national vaccination program.

Abstract
Objectives Coeliac disease has emerged as an increasingly recognised public health problem over the last half-century, and is now coming to be seen as a global phenomenon, despite a profound lack of globally representative epidemiological data. Since children with coeliac disease commonly present with chronic diarrhoea and malnutrition, diagnosis is often overlooked, particularly in poorer settings where children often fail to thrive and water-borne infectious diarrhoeas are common. This is the first attempt to make global estimates of the burden of coeliac disease in childhood. Methods We built a relatively crude model of childhood coeliac disease, incorporating estimates of population prevalence, probability of non-diagnosis, and likelihood of mortality among the undiagnosed across all countries from 1970 to 2010, based around the few available data. All our assumptions are stated in the paper and the model is available as a supplementary file. Findings Our model suggests that in 2010 there were around 2.2 million children under 5 years of age living with coeliac disease. Among these children there could be 42,000 deaths related to coeliac disease annually. In 2008, deaths related to coeliac disease probably accounted for approximately 4% of all childhood diarrhoeal mortality. Conclusions Although coeliac disease may only account for a small proportion of diarrhoeal mortality, these deaths are not preventable by applying normal diarrhoea treatment guidelines, which may even involve gluten-based food supplements. As other causes of diarrhoeal mortality decline, coeliac disease will become a proportionately increasing problem unless consideration is given to trying gluten-free diets for children with chronic diarrhoea and malnutrition.

Abstract
This case-control study was conducted in the Dhaka Hospital of ICDDR,B to identify the risk factors of mortality in severely-malnourished children hospitalized with diarrhoea. One hundred and three severely-malnourished children (weight-for-age <60% of median of the National Center for Health Statistics standard) who died during hospitalization were compared with another 103 severely-malnourished children who survived. These children were aged less than three years and admitted to the hospital during 1997. On admission, characteristics of the fatal cases and non-fatal controls were comparable, except for age. The median age of the cases and controls were six and eight months respectively (p = 0.05). Patients with low pulse rate or imperceptible pulse had three times the odds of death compared to the control group (p < 0.01). The presence of clinical septicaemia and clinical severe anaemia had 11.7 and 4.2 times the odds of death respectively (p < 0.01). Patients with leukocytosis (> 15,000/cm3) had 2.5 times the odds of death (p < 0.01). Using logistic regression, clinical septicaemia [adjusted odds ratio (AOR) = 8.8, confidence interval (CI) 3.7-21.1, p = 0.01], hypothermia (AOR = 3.5, CI 1.3-9.4, p < 0.01), and bronchopneumonia (AOR=3.0, CI 1.2-7.3, p < 0.01) were identified as the significant risk factors of mortality. Severely-malnourished children (n=129) with leukocytosis, imperceptible pulse, pneumonia, septicaemia, and hypothermia had a high risk of mortality. The identified risk factors can be used as a prognostic guide for patients with diarrhoea and severe malnutrition.

Abstract
Background Little is known about the causes of death in children in India after age five years. The objective of this study is to provide the first ever direct national and sub-national estimates of infectious disease mortality in Indian children aged 5 to 14 years. Methods A verbal autopsy based assessment of 3 855 deaths is children aged 5 to 14 years from a nationally representative survey of deaths occurring in 2001–03 in 1·1 million homes in India. Results Infectious diseases accounted for 58% of all deaths among children aged 5 to 14 years. About 18% of deaths were due to diarrheal diseases, 10% due to pneumonia, 8% due to central nervous system infections, 4% due to measles, and 12% due to other infectious diseases. Nationally, in 2005 about 59 000 and 34 000 children aged 5 to 14 years died from diarrheal diseases and pneumonia, corresponding to mortality of 24·1 and 13·9 per 100 000 respectively. Mortality was nearly 50% higher in girls than in boys for both diarrheal diseases and pneumonia. Conclusions Approximately 60% of all deaths in this age group are due to infectious diseases and nearly half of these deaths are due to diarrheal diseases and pneumonia. Mortality in this age group from infectious diseases, and diarrhea in particular, is much higher than previously estimated.

Abstract
BACKGROUND Diarrhoea is one of the leading causes of infant mortality. This article analyzes its contribution towards the realization of millennium development goal number 4 (MDG-4). METHODS A PubMed search using keywords acute infant diarrhea together with prevalence, management, or prevention 23 of the 634 generated articles were reviewed for inclusion. RESULTS WHO first expressed concern about diarrhoeal mortality in 1979. Two decades later it reported diarrhoea as the second leading cause of infant mortality worldwide. The annual death toll of 1.5 million is greater than AIDS, malaria and measles combined. Short term repercussions (dehydration, electrolyte imbalance, malnutrition, shock, death) plus long-term diminished fitness index, cognitive function, and school performance have major impact on society. Ever since its 1971 success, Oral Rehydration Therapy has been the cornerstone treatment of diarrhoea. Decreased compliance has been recorded worldwide with Kenya ranking first. Intravenous therapy is useful in preventing complications while anti-diarrhoeals and anti-microbials, are indicated in severe cases. Zinc supplementation has also proven effective, and is recommended along with rehydration. Furthermore, immunization and good hygiene prevent faecal-oral transmissions. CONCLUSION MDG-4 aims to reduce childhood mortality by 2/3 by 2015. Studies, however, show minimal progress, and the target is likely to be missed. Efforts must therefore be made to review existing strategies and formulate newer ones. Research priorities need to move away from perceived 'killer diseases' since far more children die in a day than have ever died from avian influenza for example.

Abstract
OBJECTIVES To estimate the health impact and the costs of treatment associated with rotavirus diarrhea in six yearly cohorts (2001-2006) of Mexican infants. METHODS The perspective of study is from the health care system. We estimated the effect of rotavirus diarrhea on disability adjusted life years (DALYS) and diarrhea treatment costs in hypothetical cohorts of infants who are followed from birth up to five years of age beginning in years from 2001 to 2006. We used information from administrative databases on mortality and health care from the National System of Information on Health and from the Mexican Institute for Social Security to feed a decision analysis to project the burden of disease and costs of treatment. RESULTS Estimates of DALYS were 19,426 in 2001 and decreased by 28.9% for 2006 meanwhile costs of treatment were relatively constant, estimated at US$ 38.7 million and increased only by 5%. CONCLUSION Rotavirus diarrhea in Mexican children is a major disease burden, presenting significant treatment costs. Rotavirus diarrhea mortality is decreasing; however this has not led to a steady decrease in treatment costs in the 6 years period of analysis. A sensitivity analysis showed that incidences of rotavirus diarrhea as well as the parameters associated with health-care access were the main factors, which had a significant effect on the projected burden of disease and costs.

Abstract
BACKGROUND Diarrhea remains a leading cause of mortality among young children in low- and middle-income countries. Although the evidence for individual diarrhea prevention and treatment interventions is solid, the effect a comprehensive scale-up effort would have on diarrhea mortality has not been estimated. METHODS AND FINDINGS We use the Lives Saved Tool (LiST) to estimate the potential lives saved if two scale-up scenarios for key diarrhea interventions (oral rehydration salts [ORS], zinc, antibiotics for dysentery, rotavirus vaccine, vitamin A supplementation, basic water, sanitation, hygiene, and breastfeeding) were implemented in the 68 high child mortality countries. We also conduct a simple costing exercise to estimate cost per capita and total costs for each scale-up scenario. Under the ambitious (feasible improvement in coverage of all interventions) and universal (assumes near 100% coverage of all interventions) scale-up scenarios, we demonstrate that diarrhea mortality can be reduced by 78% and 92%, respectively. With universal coverage nearly 5 million diarrheal deaths could be averted during the 5-year scale-up period for an additional cost of US$12.5 billion invested across 68 priority countries for individual-level prevention and treatment interventions, and an additional US$84.8 billion would be required for the addition of all water and sanitation interventions. CONCLUSION Using currently available interventions, we demonstrate that with improved coverage, diarrheal deaths can be drastically reduced. If delivery strategy bottlenecks can be overcome and the international community can collectively deliver on the key strategies outlined in these scenarios, we will be one step closer to achieving success for the United Nations' Millennium Development Goal 4 (MDG4) by 2015.

Abstract
BACKGROUND Vitamin A deficiency (VAD) is a major public health problem in low and middle income countries affecting 190 million children under 5. VAD can lead to many adverse health consequences, including death. OBJECTIVES To evaluate the effect of vitamin A supplementation (VAS) for preventing morbidity and mortality in children aged 6 months to 5 years. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2010 Issue 2), MEDLINE (1950 to April Week 2 2010), EMBASE (1980 to 2010 Week 16), Global Health (1973 to March 2010), Latin American and Caribbean Health Sciences (LILACS), metaRegister of Controlled Trials and African Index Medicus (27 April 2010). SELECTION CRITERIA Randomised controlled trials (RCTs) and cluster RCTs evaluating the effect of synthetic VAS in children aged 6 months to 5 years living in the community. We excluded studies concerned with children in hospital and children with disease or infection. We excluded studies evaluating the effects of food fortification, consumption of vitamin A rich foods or beta-carotene supplementation. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion. Data were double abstracted and discrepancies were resolved by discussion. Meta-analyses were performed for outcomes including all-cause and cause-specific mortality, disease, vision, and side-effects. MAIN RESULTS 43 trials involving 215,633 children were included. A meta-analysis for all-cause mortality included 17 trials comprising 194,795 children with 3536 deaths in both groups. At follow-up, there was a 24% observed reduction in the risk of all-cause mortality for Vitamin A compared with Control (Relative risk (RR) = 0.76 [95% confidence interval (CI) 0.69, 0.83]). Seven trials reported diarrhoea mortality and a 28% overall reduction for VAS (RR = 0.72 [0.57, 0.91]). There was no significant effect of VAS on cause specific mortality of measles, respiratory disease and meningitis. VAS reduced incidence of diarrhoea (RR = 0.85 [0.82, 0.87]) and measles morbidity (RR = 0.50 [0.37, 0.67]); however, there was no significant effect on incidence of respiratory disease or hospitalisations due to diarrhoea or pneumonia. There was an increased risk of vomiting within the first 48 hours of VAS (RR = 2.75 [1.81, 4.19]). AUTHORS' CONCLUSIONS VAS is effective in reducing all-cause mortality by about 24% compared to no treatment. In our opinion, given the evidence that VAS causes considerable reduction in child mortality, further placebo-controlled trials of VAS in children between 6 months and 5 years of age are not required. There is a need for further studies comparing different doses and delivery mechanisms (for example, fortification).

Abstract
BACKGROUND More than 2·3 million children died in India in 2005; however, the major causes of death have not been measured in the country. We investigated the causes of neonatal and child mortality in India and their differences by sex and region. METHODS The Registrar General of India surveyed all deaths occurring in 2001-03 in 1·1 million nationally representative homes. Field staff interviewed household members and completed standard questions about events that preceded the death. Two of 130 physicians then independently assigned a cause to each death. Cause-specific mortality rates for 2005 were calculated nationally and for the six regions by combining the recorded proportions for each cause in the neonatal deaths and deaths at ages 1-59 months in the study with population and death totals from the United Nations. FINDINGS There were 10,892 deaths in neonates and 12,260 in children aged 1-59 months in the study. When these details were projected nationally, three causes accounted for 78% (0·79 million of 1·01 million) of all neonatal deaths: prematurity and low birthweight (0·33 million, 99% CI 0·31 million to 0·35 million), neonatal infections (0·27 million, 0·25 million to 0·29 million), and birth asphyxia and birth trauma (0·19 million, 0·18 million to 0·21 million). Two causes accounted for 50% (0·67 million of 1·34 million) of all deaths at 1-59 months: pneumonia (0·37 million, 0·35 million to 0·39 million) and diarrhoeal diseases (0·30 million, 0·28 million to 0·32 million). In children aged 1-59 months, girls in central India had a five-times higher mortality rate (per 1000 livebirths) from pneumonia (20·9, 19·4-22·6) than did boys in south India (4·1, 3·0-5·6) and four-times higher mortality rate from diarrhoeal disease (17·7, 16·2-19·3) than did boys in west India (4·1, 3·0-5·5). INTERPRETATION Five avoidable causes accounted for nearly 1·5 million child deaths in India in 2005, with substantial differences between regions and sexes. Expanded neonatal and intrapartum care, case management of diarrhoea and pneumonia, and addition of new vaccines to immunisation programmes could substantially reduce child deaths in India.

Abstract
OBJECTIVE To understand the trends of diarrhea mortality rate, pre-death diagnosis and treatment of children under-5 in China, from 1996 to 2006. METHODS We used data obtained from the 1996 to 2006 national child mortality surveillance network, including 116 counties (cities) throughout China, to evaluate the under 5 mortality rate (U5MR) due to diarrhea in different geographical areas, and related factors of under 5 children mortality due to diarrhea. RESULTS Data from the national U5MR due to diarrhea fell from 249.8 in 1996 to 75.6 per 100 000 live births, in 2006. The U5MR due to diarrhea in urban reduces from 11.6 in 1996 to 6.1 per 100 000 live births in 2006, with a reduction of 47.4%. The U5MR due to diarrhea in rural decreased from 304.7 in 1996 to 94.3 per 100 000 live births in 2006, with a reduction of 69.1%. The U5MR due to diarrhea in coastal, inland and remote areas fell from 48.9, 178.9 and 566.9 in 1996 to 6.2, 30.4 and 199.2 per 100 000 live births in 2006, with a reduction of 87.3%, 83.0% and 64.9%, respectively. Among the rural children died of diarrhea, about 37.9% were diagnosed in a village clinic, 15.1% never received any diagnostic procedure. Nearly 20% of the patients had not been treated, with 50% - 60% of them had only been treated in an outpatient department. CONCLUSION During 1996 - 2006, the U5MR due to diarrhea showed a substantially downward trend in China but the disparities between urban and rural, remote and coastal, areas were increasing.

Abstract
Discovery of intestinal sodium-glucose transport was the basis for development of oral rehydration solution, and was hailed as potentially the most important medical advance of the 20th century. Before widespread use of oral rehydration solution, treatment for diarrhoea was restricted to intravenous fluid replacement, for which patients had to go to a health-care facility to access appropriate equipment. These facilities were usually neither available nor reasonable to use in the resource-poor settings most affected by diarrhoea. Use of oral rehydration solution has stagnated, despite being effective, inexpensive, and widely available. Thus, diarrhoea continues to be a leading cause of child death with consistent mortality rates during the past 5 years. New methods for prevention, management, and treatment of diarrhoea-including an improved oral rehydration formulation, zinc supplementation, and rotavirus vaccines-make now the time to revitalise efforts to reduce diarrhoea mortality worldwide.

Abstract
BACKGROUND Diarrhoea is a major cause of morbidity and mortality among infants and children worldwide, especially in low- and middle-income countries. Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is a condition that similarly disproportionately affects low- and middle-income countries; of the nearly 2.1 million children under age 15 years living with HIV/AIDS, the large majority reside in sub-Saharan Africa. Infants and children with HIV infection have more frequent and more severe diarrhoea than children without HIV. Interventions including vitamin A, zinc and cotrimoxazole may contribute substantially to preventing diarrhoea in children with HIV infection or exposure to HIV. OBJECTIVES We perform a systematic review of randomised controlled trials and nonrandomised studies that examine the effectiveness of vitamin A, zinc and cotrimoxazole on mortality and morbidity from diarrhoea in HIV-infected and -exposed infants and children. SEARCH STRATEGY Electronic databases including Pubmed, Central and EMBASE were searched without limits to language from 1980 to April 2010. Conference database searches were performed, experts were contacted and bibliographies were handsearched. SELECTION CRITERIA Randomised controlled trials (RCTs) and nonrandomised studies (NRSs) that examined the effectiveness of the three interventions were included. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed citations for eligibility and double-extracted included studies. Assessment of bias of individual studies was performed independently by both reviewers. Only two summary estimates were performed due to heterogeneity in study design and interventions. MAIN RESULTS Four RCTs were identified for vitamin A. One RCT was identified for zinc. One RCT and two NRSs were identified for cotrimoxazole. Vitamin A reduced mortality overall in children with HIV infection (four studies). A pooled estimate of three studies for reduction in mortality from vitamin A compared to placebo had a relative risk (DerSimonian and Laird method, random effects) of 0.50 (95% confidence interval (CI): 0.31 to 0.79) in 267 patients. Diarrheoa-specific mortality did not reach statistical significance and diarrhoeal morbidity outcomes were variable in three trials. Zinc supplementation reduced the number of physician visits for watery diarrhoea in one trial. Cotrimoxazole reduced mortality and hospitalisations compared to placebo in one RCT, although diarrhoea-specific morbidities were not significant. AUTHORS' CONCLUSIONS Vitamin A shows benefits in reduction of mortality in HIV-infected children. The effect of vitamin A on children with HIV exposure is not clear and needs further review. Zinc and combination vitamin A, zinc and micronutrient supplementation did not show an effect compared to vitamin A alone in children with HIV infection. Cotrimoxazole reduced mortality and some morbidity in children with HIV infection. Further research may clarify the effects of these interventions on morbidity from diarrhoea and in the population of children with HIV exposure.

Abstract
OBJECTIVES To describe the signs, histopathological features, and treatment outcome of a not previously described protein-losing enteropathy (PLE) in Rottweiler dogs. METHODS A retrospective study involving 17 Rottweilers referred for PLE. Data on sex, age, presenting signs, histopathological diagnosis, and treatment outcome were collected. The canine inflammatory bowel disease activity index (CIBDAI) score was calculated, to quantify disease severity. Endoscopic intestinal biopsies were evaluated according to the guidelines of the World Small Animal Veterinary Association (WSAVA) gastrointestinal standardization group. RESULTS Presenting signs were watery diarrhoea and weight loss. In all dogs with PLE in this study, the abnormalities found were consistent with a form of inflammatory bowel disease. Some of the dogs had a secondary infection with Giardia or Cyniclomyces guttulatus. In 10 dogs (59%) the CIBDAI score was 9 or higher, indicative of severe disease. Histopathological findings revealed lymphoplasmacellular enteritis, with lymphangiectasia in 14 (82%) dogs and eosinophil infiltration in 10 (59%) dogs. Eleven (65%) dogs were euthanized or died because of the intestinal disease. Kaplan-Meier analysis revealed a median survival time of 5 months, with a 1-year survival rate of 47%. Seven (4%) dogs were disease-free after treatment with immunosuppressants and dietary measures, but some relapsed (median disease-free interval 21 months). CLINICAL SIGNIFICANCE In Rottweilers presenting with chronic diarrhoea and weight loss, clinicians should consider the presence of severe PLE, which has a poor prognosis.

Abstract
OBJECTIVES Diarrhea is the second cause of child morbidity and mortality in Morocco after acute respiratory infection. Each child suffers from 4 to 8 episodes of diarrhea per year. The purpose of this study was to evaluate the knowledge as well as diagnostic and therapeutic practices of general practitioners regarding children presenting with diarrhea. METHODS Study was based on an epidemiologic survey using a written questionnaire completed by general practitioners in state-run hospitals in the Marrakesh (Tensift El Haouz) region. The anonymous questionnaire containing items on the epidemiological, clinical, laboratory, and therapeutic aspects was distributed in all 5 medical districts in the region. RESULTS Analysis of reponses concerning therapeutic practices showed heavy reliance on oral rehydration that was prescribed by 98.2% of general practitioners. Dietary analysis was performed by only 24% of practitioners and blood/stool testing was not systematically ordered. Only 3% of practitioners recommended early resumption of feeding. However, data showed excessive use of additional laboratory tests (57.8%) and prescription drugs (48.8%). Overprescription mainly involved antiemetics and anti-diarrheals (77.7%). CONCLUSION This study demonstrates an urgent need to develop a strategy to improve the quality of dietary management of diarrhea by general practitioners and rationalize prescription drug use. A continuing medical education program would be useful to increase the awareness of general practitioners and reduce child/infant morbidity and mortality relating to this disease.

Abstract
BACKGROUND Several mortality estimates for the Darfur conflict have been reported since 2004, but few accounted for conflict dynamics such as changing displacement and causes of deaths. We analyse changes over time for crude and cause-specific mortality rates, and assess the effect of displacement on mortality rates. METHODS Retrospective mortality surveys were gathered from an online database. Quasi-Poisson models were used to assess mortality rates with place and period in which the survey was done, and the proportions of displaced people in the samples were the explanatory variables. Predicted mortality rates for five periods were computed and applied to population data taken from the UN's series about Darfur to obtain the number of deaths. FINDINGS 63 of 107 mortality surveys met all criteria for analysis. Our results show significant reductions in mortality rates from early 2004 to the end of 2008, although rates were higher during deployment of fewer humanitarian aid workers. In general, the reduction in rate was more important for violence-related than for diarrhoea-related mortality. Displacement correlated with increased rates of deaths associated with diarrhoea, but also with reduction in violent deaths. We estimated the excess number of deaths to be 298 271 (95% CI 178 258-461 520). INTERPRETATION Although violence was the main cause of death during 2004, diseases have been the cause of most deaths since 2005, with displaced populations being the most susceptible. Any reduction in humanitarian assistance could lead to worsening mortality rates, as was the case between mid 2006 and mid 2007.

Abstract
OBJECTIVE To assess associations between maternal child marriage (marriage before age 18) and morbidity and mortality of infants and children under 5 in India. Design Cross-sectional analyses of nationally representative household sample. Generalised estimating equation models constructed to assess associations. Adjusted models included maternal and child demographics and maternal body mass index as covariates. Setting India. Population Women aged 15-49 years (n=124 385); data collected in 2005-6 through National Family Health Survey-3. Data about child morbidity and mortality reported by participants. Analyses restricted to births in past five years reported by ever married women aged 15-24 years (n=19 302 births to 13 396 mothers). MAIN OUTCOME MEASURES In under 5s: mortality related infectious diseases in the past two weeks (acute respiratory infection, diarrhoea); malnutrition (stunting, wasting, underweight); infant (age <1 year) and child (1-5 years) mortality; low birth weight (<2500 kg). Results The majority of births (73%; 13 042/19 302) were to mothers married as minors. Although bivariate analyses showed significant associations between maternal child marriage and infant and child diarrhoea, malnutrition (stunted, wasted, underweight), low birth weight, and mortality, only stunting (adjusted odds ratio 1.22, 95% CI 1.12 to 1.33) and underweight (1.24, 1.14 to 1.36) remained significant in adjusted analyses. We noted no effect of maternal child marriage on health of boys versus girls. Conclusions The risk of malnutrition is higher in young children born to mothers married as minors than in those born to women married at a majority age. Further research should examine how early marriage affects food distribution and access for children in India.

Abstract
REASONS FOR PERFORMING STUDY The incidence and implications of positive blood cultures in mature horses with diarrhoea is unknown. The diagnosis of bacteraemia may alter treatment and prognosis. HYPOTHESIS The proportion of horses with diarrhoea that are blood culture positive is higher than previously assumed and a positive blood culture has a negative impact on survival. METHODS Blood cultures were taken at admission and 24 h after admission from 31 mature horses with diarrhoea. RESULTS Nine (29%) horses were blood culture positive within 24 h of admission. Organisms isolated included Corynebacterium spp. (n = 6), Streptococcus spp. (n = 2), Pantoea agglomerans (n = 1), Gram-negative rod (n = 1), Bacillus spp. (n = 1) and yeast (n = 1). Horses with positive blood cultures were significantly less likely to survive. Prior treatment with antimicrobial drugs had no significant effect on blood culture status. Horses with positive blood cultures had a significantly higher heart rate, packed cell volume (PCV) and plasma potassium concentration at admission, and a higher PCV and lower total plasma protein concentration 24 h after admission. CONCLUSIONS Positive blood cultures occur more frequently than previously reported, and may have a negative impact on survival in horses with diarrhoea. POTENTIAL RELEVANCE Results of blood cultures may be useful in formulating a prognosis for horses with diarrhoea. Further research is required to determine the effect of antimicrobial treatment on outcome.

Abstract
This case-control study examines whether chronic diarrhea at initiation of antiretroviral therapy (ART) affects survival of human immunodefiency virus-infected patients. Cases (288) were treatment-naive, non-pregnant, adults with self report of frequent loose stool for > 3 weeks at the time ART was initiated. One-third of patients had an enteric pathogen identified including Cryptosporidium spp., Giardia spp., Isospora belli, Cyclospora cayetanensis, and Entamoeba histolytica. Control patients (400) did not have diarrhea when initiating ART. At six weeks, mortality was 10% in the patients with diarrhea and 5% in the patients without diarrhea (P = 0.009). Chronic diarrhea in patients requesting ART in Haiti is associated with increased early mortality.

Abstract
The objectives of our study were to describe the epidemiology of child-health indicator diseases in western Jamaica, examine differences in indicator diseases between sex and age, and generate hypotheses about causes of disease burden. International Classification of Disease, 10th Revision, coded discharge diagnoses were collected from consecutive admissions for 2003-2005 from a public tertiary care hospital. Mortality data were not coded. Perinatal disease was the most common cause of mortality, with hyaline membrane disease the primary cause. Younger children, particularly males, are disproportionately affected by all indicator diseases (P < 0.001) and more likely to die from acute respiratory tract infections and infectious diseases (P < 0.05). Sickle cell disease was the fourth most common diagnosis. Children in western Jamaica are most affected by diseases of prematurity. These children experience disease burden similar to that of children in other developing countries, but fewer neonatal sepsis and insect-borne infections, and more hematologic illness.
