Abstract
Objectives Acute diarrhea in children is generally managed by replacing the lost fluid with oral rehydration solution (ORS). Probiotic supplementation has been reported to reduce the severity of diarrhea. In the present study, we investigated the effect of Weizmannia coagulans (Bacillus coagulans) MTCC 5856, along with ORS on acute diarrhea of all causes in non-hospitalized children. Methods A total of 110 children of ages between 1 and 10 were enrolled in a double-blind placebo-controlled study and were randomly allocated to receive W. coagulans MTCC 5856 (4 × 108 spores, N = 54) + ORS and zinc (Zn) or a placebo (N = 56) + ORS and (Zn) for 5 days. The consistency of the stool, mean duration of diarrhea in hours, mean diarrhea frequency per day, and the dehydration status were collected as efficacy endpoints. Safety was evaluated by the occurrence of adverse events. Results The mean age of the children was 5.55 ± 2.57 years (61 boys and 49 girls). The mean duration of diarrhea was 51.31 ± 20.99 h in the W. coagulans MTCC 5856 group and 62.74 ± 24.51 h in the placebo (p = 0.011) group. The frequency of diarrhea was lower in children supplemented with the probiotic, but the difference was not statistically significant. The perceived efficacy score and dehydration status improved significantly in the W. coagulans MTCC 5856 group compared with the placebo group. No adverse events were recorded. Conclusion The results of the study suggest that W. coagulans MTCC 5856 could be supplemented along with ORS and zinc to reduce the duration of diarrhea in non-hospitalized children. Clinical Trial Registration ClinicalTrials.gov, identifier CTRI/2022/06/043239.

Abstract
INTRODUCTION The escalating prevalence of infectious diseases is an important cause of concern in society. Particularly in several developing countries, infectious diarrhea poses a major problem, with a high fatality rate, especially among young children. The condition is divided into four classes, namely, acute diarrhea, invasive diarrhea, acute bloody diarrhea, and chronic diarrhea. Various pathogenic agents, such as bacteria, viruses, protozoans, and helminths, contribute to the onset of this condition. AREAS COVERED The review discusses the scenario of infectious diarrhea, the prevalent types, as well as approaches to management including preventive, therapeutic, and vaccination strategies. The vaccination techniques are extensively discussed including the available vaccines, their advantages as well as limitations. EXPERT OPINION There are several approaches available to develop new-improved vaccines. In addition, route of immunization is important and aerosols/nasal sprays, oral route, skin patches, powders, and liquid jets to minimize needles can be used. Plant-based vaccines, such as rice, might save packing and refrigeration costs by being long-lasting, non-refrigerable, and immunogenic. Future research should utilize predetermined PCR testing intervals and symptom monitoring to identify persistent pathogens after therapy and symptom remission.

Abstract
Viral hepatitis is a major public health concern globally. World health organization aims at eliminating viral hepatitis as a public health threat by 2030. Among the hepatitis causing viruses, hepatitis B and C are primarily transmitted via contaminated blood. Hepatitis A and E, which gets transmitted primarily via the feco-oral route, are the leading cause of acute viral hepatitis. Although vaccines are available against some of these viruses, new cases continue to be reported. There is an urgent need to devise a potent yet economical antiviral strategy against the hepatitis-causing viruses (denoted as hepatitis viruses) for achieving global elimination of viral hepatitis. Although zinc was known to mankind for a long time (since before Christ era), it was identified as an element in 1746 and its importance for human health was discovered in 1963 by the pioneering work of Dr. Ananda S. Prasad. A series of follow up studies involving zinc supplementation as a therapy demonstrated zinc as an essential element for humans, leading to establishment of a recommended dietary allowance (RDA) of 15 milligram zinc [United States RDA for zinc]. Being an essential component of many cellular enzymes and transcription factors, zinc is vital for growth and homeostasis of most living organisms, including human. Importantly, several studies indicate potent antiviral activity of zinc. Multiple studies have demonstrated antiviral activity of zinc against viruses that cause hepatitis. This article provides a comprehensive overview of the findings on antiviral activity of zinc against hepatitis viruses, discusses the mechanisms underlying the antiviral properties of zinc and summarizes the prospects of harnessing the therapeutic benefit of zinc supplementation therapy in reducing the disease burden due to viral hepatitis.

Abstract
Cryptosporidium species and Giardia duodenalis are infectious intestinal protozoan pathogens that cause alarming rates of morbidity and mortality worldwide. Children are more likely to have clinical symptoms due to their less developed immune systems and factors such as undernutrition, especially in low- and middle-income countries. The severity of the symptoms and clinical manifestations in children may vary from asymptomatic to life-threatening depending on the Cryptosporidium species/G. duodenalis strains and the resulting complex stepwise interactions between the parasite, the host nutritional and immunologic status, and the gut microbiome profile. Structural damages inflicted by both parasites to epithelial cells in the large and small intestines could severely impair children's gut health, including the ability to absorb nutrients, resulting in stunted growth, diminished neurocognitive development, and other long-term effects. Clinically approved cryptosporidiosis and giardiasis drugs have broad antimicrobial effects that have incomprehensible impacts on growing children's gut health.

Individual and community level factors associated with medical treatment-seeking behavior for childhood diarrhea among the Gambian mothers: evidence from the Gambian demographic and health survey data, 2019/2020. BMC Public Health 2023; 23:579. [PMID: 36978028 PMCID: PMC10045107 DOI: 10.1186/s12889-023-15493-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Accepted: 03/21/2023] [Indexed: 03/30/2023] Open
Abstract
INTRODUCTION In less developed countries, including the Gambia, childhood diarrhea is one of the leading causes of serious illness and death among children. Studies on wider determinants of behaviors in medical treatment seeking for diarrheal illnesses in poor resource settings are limited. However, the challenges are continuing and, there is a gap in research work about it in the Gambia. Therefore, the rationale of this study was to assess the individual and community level factors of medical treatment-seeking behaviors for childhood diarrhea among mothers in the Gambia. METHODS Data from the 2019-20 Gambia demographic and health survey were used in this study, which was based on secondary data analysis. A total of 1,403 weighted samples of under-five children's mothers were included in the study for diarrhea medical treatment-seeking behaviors. Because of the hierarchical nature of the data, a multi-level logistic regression model was applied to identify individual and community-level factors that may influence mothers' medical treatment-seeking behaviors of diarrhea. Data were analyzed using multilevel logistic regression analysis. In the multivariable multilevel logistic regression analysis, variables were judged significantly linked with medical treatment-seeking behavior of diarrhea if their p-value was less than 0. 05. RESULTS Medical treatment-seeking behaviors for diarrhea were discovered in 62.24% (95% CI: 59.67,64.74) of mothers of under five children. Being a female child has shown odds of (AOR = 0.79, (CI 95%: (0.62,0.98)) times less treatment-seeking behavior than the counterparts. Moreover, compared to mothers whose children were of average size, those whose children were smaller, and larger than average at birth were more likely to seek out pediatric medical treatment (AOR = 1.53, 95% CI (1.08-2.16), and (AOR = 1.31, 95% CI (1.01,1.169)) respectively. On the other side, mothers who have exposure to listening to the radio, and heard about oral rehydration have shown an odds of (AOR = 1.34, CI 95%, (1.05,1.72)), (AOR = 2.21, CI 95%, (1.14,4.30)), being from the middle, and rich household wealth have also shown (AOR = 2.15, CI 95%, (1.32,3.51)), and (AOR = 1.92, (CI 95%, (1.11,3.32)), a child with cough, and fever (AOR = 1.44, CI 95%, (1.09,1.89)), and (AOR = 1.73, CI 95%, (1.33,2.25)) were individual-level factors that have shown association statistically with the outcome variable. Similarly, regarding community level factors mothers who had a postnatal checkup, and those from the Kerewan region have revealed more odds of (AOR = 1.48, CI 95%, (1.08,2.02)), and (AOR = 2.99, CI 95%, (1.32,6.78)) times significantly with treatment seeking behavior of mothers respectively. CONCLUSION Diarrhea medical treatment-seeking behavior was found low. Hence, it remains among the top public health challenges in the Gambia. Strengthening mothers' healthcare-seeking behavior and skills on home remedies, and childhood illnesses, advocating mass media exposure, assisting financially disadvantaged mothers, and postnatal checkups after delivery will enhance medical treatment-seeking behavior. Furthermore, coordinating with regional states, and designing timely policies and interventions are highly advisable in the country.

Abstract
BACKGROUND Some studies have reported the possible role of vitamin D3 in ameliorating disease outcomes in childhood infectious diarrhea. However, findings about its effectiveness and the association of serum vitamin D levels with diarrhea risk appear inconsistent. We aimed to determine the efficacy of oral vitamin D3 as an adjunct in managing childhood infectious diarrhea and the relationship between vitamin D status and the disease. METHODS We searched the PubMed and Google Scholar electronic databases for relevant articles without limiting their year of publication. We selected primary studies that met the review's inclusion criteria, screened their titles and abstracts, and removed duplicates. We extracted data items from selected studies using a structured data-extraction form. We conducted a quality assessment of randomized controlled trials (RCTs) and non-randomized studies with the Cochrane collaboration tool and the Newcastle Ottawa Scale, respectively. We assessed the strength of the relationship between serum vitamin D levels and diarrhea using the correlation model. We estimated the I2 and tau2 values to assess between-study heterogeneity. RESULTS Nine full-text articles were selected, consisting of one RCT, three cross-sectional studies, two cohort studies, two longitudinal/prospective studies, and one case-control study. A total of 5,545 participants were evaluated in the nine studies. Six non-randomized studies provided weak evidence of the relationship between vitamin D levels and diarrhea risk as there was no correlation between the two variables. The only RCT failed to demonstrate any beneficial role of vitamin D3 in reducing the risk of recurrent diarrhea. The calculated I2 and tau2 values of 86.5% and 0.03, respectively suggested a high between-study heterogeneity which precluded a meta-analysis of study results. CONCLUSION Oral vitamin D3 may not be an effective adjunct in managing childhood infectious diarrhea. Additionally, the relationship between vitamin D status and infectious diarrhea appears weak. We recommend more adequately-powered RCTs to determine the effectiveness of vitamin D3 as an adjunct therapy in infectious diarrhea.

Abstract
Worldwide, diarrhoea in children under five years of age is the second leading cause of death. Despite having high morbidity and mortality, diarrhoeal diseases can be averted by simple and cost-effective interventions. The Integrated Management of Childhood Illness (IMCI) has proposed the use of Oral Rehydration Salt (ORS) and zinc together with adequate food and fluid intake for the management of acute non-dysenteric watery diarrhoea in children. In the past, few studies examined the determinants of adherence to diarrhoea case management. Therefore, this study measured the determinants of therapeutic and dietary adherence to diarrhoea case management using the third and fourth wave of Pakistan Demographics and Health Surveys (PDHS) datasets. Data from 4068 children between 0 to 59.9 months with positive history of diarrhoea were included, while data on children with dysentery, severe dehydration, and co-morbid condition was excluded. This study reported therapeutic adherence in less than 10% of children in Pakistan, while dietary adherence was reported in 39.2% of children (37.7% in 2012–2013 and 40.7% in 2017–2018). A significant improvement in therapeutic (0.8% in 2012–2013 and 8.1% in 2017–2018) and dietary adherence (37.7% in 2012–2013 and 40.7% in 2017–2018) was reported in the 2017–2018 survey compared to the 2012–2013 survey. In general, children over the age of one year (compared to children <1 year) and of the richer/richest socioeconomic class (compared to poorest/poorer socioeconomic class) showed higher therapeutic and dietary adherence. Therapeutic and dietary adherence among diarrhoeal children can be improved by increasing the awareness and accessibility of ORS, zinc, and essential foods.

Abstract
Cholera, caused by Vibrio cholerae, persists in developing countries due to inadequate access to safe water, sanitation, and hygiene. There are approximately 4 million cases and 143,000 deaths each year due to cholera. The disease is transmitted fecally-orally via contaminated food or water. Severe dehydrating cholera can progress to hypovolemic shock due to the rapid loss of fluids and electrolytes, which requires a rapid infusion of intravenous (i.v.) fluids. The case fatality rate exceeds 50% without proper clinical management but can be less than 1% with prompt rehydration and antibiotics. Oral cholera vaccines (OCVs) serve as a major component of an integrated control package during outbreaks or within zones of endemicity. Water, sanitation, and hygiene (WaSH); health education; and prophylactic antibiotic treatment are additional components of the prevention and control of cholera. The World Health Organization (WHO) and the Global Task Force for Cholera Control (GTFCC) have set an ambitious goal of eliminating cholera by 2030 in high-risk areas.

Abstract
INTRODUCTION Diarrhea causes a loss of body water and salt, which can lead to dehydration and death. The use of oral rehydration salts and zinc together is regarded as an effective treatment for diarrhea in resource-poor settings like Ethiopia. However, studies that examine the co-utilization of oral rehydration solution and zinc in the treatment of diarrhea are limited Ethiopia. OBJECTIVE To assess the prevalence and associated factors of oral rehydration solution and zinc co-utilization to treat diarrhea in children under the age of five in Ethiopia, EDHS 2016. METHODS Secondary data from the 2016 Ethiopia Demographic and Health Survey (EDHS) was used to investigate the prevalence and factors associated with the co-utilization of ORS and zinc to treat diarrhea in under-five children. A multilevel binary logistic regression model was fitted to identify factors associated with the co-utilization of ORS and zinc. Adjusted odds ratios (AOR) with 95% CI were calculated and used as a measure of associations, and variables having a p-value of less than 0.05 were declared as statistically significant. RESULTS The national prevalence of ORS and zinc co-utilization was 16.65% (14.66%, 18.84%). Maternal educational status (AOR = 1.45; 95% CI; (1.01, 2.09)), household size (AOR = 1.53; 95% CI; 1.09, 2.16) and distance to health facilities at the community level (AOR = 1.60, 95% CI = 1.02, 2.58) were variables significantly associated with the co-use of ORS and zinc. CONCLUSION The co-utilization of ORS and zinc for the management of diarrhea was low in Ethiopia. Education, household size, and distance to health facilities at the community level were significantly associated with the co-utilization of ORS and zinc in Ethiopia.

Abstract
Child malnutrition is one of the biggest problems in developing countries with higher level of food insecurity. Pakistan is 5th largest producer of date fruit; therefore, its processing and products should be explored in various dimensions. Being rich source of minerals and sugars, it can contribute in weaning foods in a good manner. In current study, three blends were prepared with specific proportions of spray-dried date powder and rich in specific proportions. They were compared with each other and control (free of date powder). The nutritional profile of the formulations revealed that 100 g of each formulation included all macronutrients in compliance with the requirements of Food and Agriculture Organization for weaning formulations; moreover, they are enriched with minerals due to presence of date powder. The iron contents reached up to 12.74 ± 0.16 mg/100 g. The phosphorus, zinc, and potassium contents also increased with the increase in date powder subsequently. Physicochemical properties exhibited in compliance with the requirement of the weaning foods. The protein quality was assessed both in vivo and in vitro. Amino acid profiling indicated that the limiting amino acid in F1 and control were lysine but in F2 and F3 were threonine. This is suggested that date powder might contain good quality protein that was further explained in biological studies, the formulations that contained higher amount of date powder reveled better PDCAAS score 86.76 ± 4.5, true digestibility 84 ± 4.36, biological value 69.45 ± 0.69, net protein utilization 73.82 ± 1.46, and protein efficiency score 1.18 ± 0.07. The sensory evaluation revealed that F2 showed better result in overall acceptability. Thus, date powder is suggested to be used as good constituent that can fortify mineral contents and sugar contents of the weaning foods.

Abstract
BACKGROUND Acute diarrhea is a major cause of mortality in children. Few studies have addressed the administration of lactose-restricted diets in breastfed children with acute diarrhea. The present study was conducted to investigate the effects of a lactose-restricted regimen on breastfed children with acute diarrhea treated with zinc supplements. METHODS The present single-blind randomized clinical trial was conducted on children aged 6-24 months in Amirkola Children's Hospital (2015-2017). 90 children were randomly assigned to two groups. Group A was daily treated with 20 mg of zinc and a lactose-restricted diet and breast milk for two weeks. Group B received 20 mg of zinc and breast milk and an age-appropriate diet for two weeks. The data collected in all the subjects included the frequency of diarrhea and the mean duration of hospitalization and recovery from diarrhea. RESULTS The two groups were not significantly different in terms of mean age, weight and ratio of males to females. The mean duration of hospitalization was found to be 3.1 ± 0.8 days in group A and 3.2 ± 0.6 in group B (P = 0.3), the mean duration of recovery to be 2.9 ± 0.8 in group A and 2.6 ± 1.1 in group B (P = 0.2) and the mean frequency of diarrhea 2.9 ± 0.7 in group A and 2.8 ± 0.8 days in group B (P = 0.5), suggesting no significant differences between the two groups. No adverse effects associated with zinc therapy were reported. CONCLUSIONS A lactose-restricted regimen was found not to be beneficial for children with acute diarrhea under continuous breastfeeding and zinc therapy.

Abstract
BACKGROUND Acute diarrhea constitutes a major global burden to morbidity and mortality in under-five children. Research has shown that micronutrient zinc plays a pivotal role in childhood diarrhea; however, there are contradictory reports of its therapeutic benefit across the various causative enteropathogens. OBJECTIVES The aim of the study was to determine the prevalence of viral etiology (rotavirus, adenovirus, and norovirus) and compare the serum zinc levels of children with acute diarrhea. METHODS A comparative cross-sectional study in which 100 hospitalized children with acute diarrhea aged one-59 months and 100 controls were recruited. Viruses were investigated from stool specimens using the immunochromatographic technique, while serum zinc was determined through the colorimetric method. Data analysis was with SPSS 20 software package. RESULTS The prevalence of viruses in the subjects was 62.0% with rotavirus isolated in 30 (30.0%) of the patients, while adenovirus and norovirus were detected in 21 (21.0%) and 11 (11.0%) patients, respectively. Rotavirus was the only virus detected in 2 (2.0%) of the controls. The mean serum zinc level of 65.3 ± 7.4 µg/dl in the subjects was significantly lower than 69.0 ± 6.5µg/dl in the controls (P < 0.001). The prevalence of zinc deficiency in the subjects (47.0%) was significantly higher than 32.0% in the controls (P = 0.030). The mean serum zinc levels differed significantly among the viruses isolated in the subjects (P < 0.001). CONCLUSIONS Viruses contribute largely to etiology of acute diarrhea in Nigerian under-five children. Zinc deficiency was also highly prevalent in the study population. The serum zinc levels varied significantly across the different viruses isolated.

Abstract
Lawsonia intracellularis is among the most important enteric pathogens of swine and antibiotic alternatives are needed to help mitigate the negative effects of infection. Zinc is an essential trace mineral known to be crucial for maintaining intestinal barrier function and proper immune response. In this study, we investigated the porcine host response to L. intracellularis infection when supplemented with a zinc-amino acid complex, a form of zinc that can lead to greater bioavailability when compared to traditional inorganic forms of zinc. Our results show that a zinc-amino acid complex supplementation with a final concentration of 125 ppm of zinc in feed significantly (p < 0.05) decreased the number of animals with lesions and severity of lesions caused by L. intracellularis. Animals supplemented with the zinc-amino acid complex also exhibited a significantly (p < 0.05) earlier onset of seroconversion as well as an increased number of T cells in infected and non-infected intestinal tissue. This study demonstrated that this zinc-amino acid complex aids the host in responding to L. intracellularis infection and may be a new approach to help minimize negative effects of disease.

Abstract
After the discovery of zinc deficiency in the 1960s, it soon became clear that zinc is essential for the function of the immune system. Zinc ions are involved in regulating intracellular signaling pathways in innate and adaptive immune cells. Zinc homeostasis is largely controlled via the expression and action of zinc "importers" (ZIP 1-14), zinc "exporters" (ZnT 1-10), and zinc-binding proteins. Anti-inflammatory and anti-oxidant properties of zinc have long been documented, however, underlying mechanisms are still not entirely clear. Here, we report molecular mechanisms underlying the development of a pro-inflammatory phenotype during zinc deficiency. Furthermore, we describe links between altered zinc homeostasis and disease development. Consequently, the benefits of zinc supplementation for a malfunctioning immune system become clear. This article will focus on underlying mechanisms responsible for the regulation of cellular signaling by alterations in zinc homeostasis. Effects of fast zinc flux, intermediate "zinc waves", and late homeostatic zinc signals will be discriminated. Description of zinc homeostasis-related effects on the activation of key signaling molecules, as well as on epigenetic modifications, are included to emphasize the role of zinc as a gatekeeper of immune function.

Abstract
Lentil is a major cool-season grain legume grown in South Asia, West Asia, and North Africa. Populations in developing countries of these regions have micronutrient deficiencies; therefore, breeding programs should focus more on improving the micronutrient content of food. In the present study, a set of 96 diverse germplasm lines were evaluated at three different locations in India to examine the variation in iron (Fe) and zinc (Zn) concentration and identify simple sequence repeat (SSR) markers that associate with the genetic variation. The genetic variation among genotypes of the association mapping (AM) panel was characterized using a genetic distance-based and a general model-based clustering method. The model-based analysis identified six subpopulations, which satisfactorily explained the genetic structure of the AM panel. AM analysis identified three SSRs (PBALC 13, PBALC 206, and GLLC 563) associated with grain Fe concentration explaining 9% to 11% of phenotypic variation and four SSRs (PBALC 353, SSR 317-1, PLC 62, and PBALC 217) were associated with grain Zn concentration explaining 14%, to 21% of phenotypic variation. These identified SSRs exhibited consistent performance across locations. These candidate SSRs can be used in marker-assisted genetic improvement for developing Fe and Zn fortified lentil varieties. Favorable alleles and promising genotypes identified in this study can be utilized for lentil biofortification.

Abstract
BACKGROUND Among the preventive strategies for lowering the incidence of upper respiratory tract infections (URTI) and acute diarrhoea episodes, two of the most common diseases in children, zinc supplementation has received special interest. However, there is a need for additional studies that determine the preventive effects of different doses of zinc on URTI and diarrhoeal disease episodes in children. METHODS In a randomised, triple-blind clinical trial, we evaluated the efficacy of 12 months of daily zinc supplementation in the incidence of URTI and acute diarrhoea in a population of healthy children aged between 6 and 12 months living in Bogota, Colombia. The outcomes analysed were incidence of URTI, acute diarrhoeal disease episodes, and side effects of the interventions. RESULTS Between 2010 and 2013, a total of 355 children underwent randomisation, with 174 assigned to the zinc supplementation group and 181 to the control group. In the multivariate analyses, having been randomised to the non-supplemented control group (IRR 1.73, 95% CI 1.52-1.97, p<0.001), and nursery attendance (IRR 1.41, 95% CI 1.07-1.87, p=0.016) were independently linked to the number of URTI. Likewise, having been randomised to the non-supplemented group (IRR 1.43, 95% CI 1.20-1.71, p<0.001), and lower socioeconomic status (IRR 1.86, 95% CI 1.11-3.13, p=0.018) were independently associated to the number of diarrhoeal disease episodes. CONCLUSIONS Daily supplementation of 5mg of zinc during 12 months significantly decreased the incidence of URTI and diarrhoeal disease episodes in a healthy population of children aged between 6 and 12 months.

Abstract
UNLABELLED We designed a double-blinded randomized clinical trial of zinc (10 or 20 mg of zinc sulphate for 2-5 month-old or 6-59 month-old children, respectively, during 10 days) vs. placebo in otherwise healthy children aged 2 months to 5 years who presented with acute diarrhoea (i.e. ≥3 stools/day for less than 72 h). Eighty-seven patients (median age 14 months; range 3.1-58.3) were analysed in an intention-to-treat approach. Forty-two patients took zinc and 45 placebo. There was no difference in the duration nor in the frequency of diarrhoea, but only 5% of the zinc group still had diarrhoea at 120 h of treatment compared to 20% in the placebo group (P = 0.05). Thirty-one patients (13 zinc and 18 placebo) were available for per-protocol analyses. The median (IQR) duration of diarrhoea in zinc-treated patients was 47.5 h (18.3-72) and differed significantly from the placebo group (median 76.3; IQR 52.8-137) (P = 0.03). The frequency of diarrhoea was also lower in the zinc group (P = 0.02). CONCLUSION zinc treatment decreases the frequency and severity of diarrhoea in children aged 2 months to 5 years living in Switzerland. However, the intention-to-treat analysis reveals compliance issues that question the proper duration of treatment and the choice of optimal pharmaceutical formulation.

Abstract
Diarrhea is the third leading cause of childhood mortality in India, and is responsible for 13% of all deaths/year in children under 5 years of age. Information on diarrheal diseases, its determinants and preventive and control strategies need to be reviewed for better planning and organization of health services. This study reviewed literature on diarrheal disease control among under-five children in India from literature published in PubMed, Google search engine and other databases on the internet. Data were described in terms of disease burden in India, determinants, management and intervention strategies, preventive strategies, and role of public health and scope for future action. This review calls for a comprehensive diarrheal disease control strategy, through improved case management, addressing social determinants of health and research in the field of cost-effective interventions to reduce the burden of diarrhea among children in India. With < almost one year left to reach the 2015 Millennium Development Goal on reducing child mortality, progress on control of diarrheal diseases must be accelerated.

Abstract
PURPOSE/OBJECTIVE The evolving Non-Governmental Organization (NGO) sector in Bangladesh provides health services directly, however some NGOs indirectly provide services by working with unlicensed providers. The primary objective of this study was to examine the impact of NGO training of unlicensed providers on diarrhoea management and the scale up of zinc treatment in rural populations. METHODS An uncontrolled, single-arm trial for a training and support intervention on diarrhoea outcomes was employed in a rural sub-district of Bangladesh during 2008. Two local NGOs and their catchment populations were chosen for the study. The intervention included training of unlicensed health care providers in the management of acute childhood diarrhoea, particularly emphasizing zinc treatment. In addition, community-based promotion of zinc treatment was carried out. Baseline and endline ecologic surveys were carried out in intervention and control villages to document changes in treatments received for diarrhoea in under-five children. RESULTS Among surveyed household with an active or recent acute childhood diarrhoea episode, 69% sought help from a health provider. Among these, 62.8% visited an unlicensed private provider. At baseline, 23.9% vs. 22% of control and intervention group children with diarrhoea had received zinc of any type. At endline (6 months later) this had changed to 15.3% vs. 30.2%, respectively. The change in zinc coverage was significantly higher in the intervention villages (p<0.01). Adherence with giving zinc for 10 days or more was significantly higher in the intervention households (9.2% vs. 2.5%; p<0.01). Child's age, duration of diarrhoea, type of diarrhoea, parental year of schooling as well as oral rehydration solution (ORS) and antibiotic usage were significant predictors of zinc usage. CONCLUSION Training of unlicensed healthcare providers through NGOs increased zinc coverage in the diarrhoea management of under-five children in rural Bangladesh households.

Abstract
BACKGROUND Diarrhea's impact on childhood morbidity can be reduced by administering oral rehydration solution (ORS) with zinc; challenges to wider use are changing health-seeking behavior and ensuring access. METHODS We conducted a randomized controlled trial to increase ORS plus zinc uptake in rural Myanmar. Village tracts, matched in 52 pairs, were randomized to standard ORS access vs. a social franchising program training community educators and supplying ORS plus zinc. RESULTS Intervention and control communities were comparable on demographics, prevalence of diarrhea and previous use of ORS. One year after randomization, ORS plus zinc use was 13.7% in the most recent case of diarrhea in intervention households compared with 1.8% in control households (p < 0.001) (N = 3605). A significant increase in ORS plus zinc use was noted in the intervention (p = 0.044) but not in the control (p = 0.315) group. CONCLUSIONS Social franchising increased optimal treatment of childhood diarrhea in rural Myanmar. Scale-up stands to reduce morbidity among children in similar settings.

Abstract
Diarrhea continues to stand among the most important causes of global morbidity and mortality in children under 5 years of age. Although the introduction of oral rehydration and other case-management strategies have reduced acute diarrhea fatalities, many of the survivors develop persistent diarrhea and/or deficiencies of growth and cognition. Thus understanding the true global burden of diarrhea requires attention to acute diarrhea as well is its sequelae. To understand the etiology of moderate to severe diarrhea among children in high mortality areas of sub-Saharan Africa and south Asia we performed a comprehensive case-control study of children under 5 years of age at seven sites. Each site employed an identical case-control study design and each utilized a uniform comprehensive set of microbiological assays to identify the likely bacterial, viral and protozoal etiologies. Results of the studies will inform diarrhea prevention and management efforts worldwide.
