[PMID: 34293678 DOI: 10.1016/j.socscimed.2021.114185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Revised: 06/14/2021] [Accepted: 06/26/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVES This paper uses a survival analysis technique to examine socio-economic and demographic factors that influence under-five mortality for rural and urban Ghana. METHOD The paper employs the Breslow Method for Ties for survival probability and uses data for the 2014 Ghana Demographic and Health Survey (GDHS). Data on some 5884 children was also generated through the interview of 4086 women aged 15-49. They indicated the birth histories of the children under five years. RESULTS The study finds the most significant socio-economic determinants of a child survival in Ghana to be maternal age, mother's education, household wealth index quintile, place of delivery and birth order. The influence of these determinants on child survival differ from urban to rural. CONCLUSION The survival probabilities of these explanatory variables are different in the rural area from the urban area. Therefore, it is imperative to scale up efforts in the rural area to ensure children live up to age five.

Impact of Routine Counseling on Breastfeeding Status in Hospitalized Infants Below 6 Months: Observation From a Large Diarrheal Disease Hospital in Bangladesh. Glob Pediatr Health 2019; 6:2333794X19854942. [PMID: 31236430 PMCID: PMC6572883 DOI: 10.1177/2333794x19854942] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Revised: 05/07/2019] [Accepted: 05/10/2019] [Indexed: 11/15/2022] Open
Abstract
Background. Breastfeeding counseling (BFC) plays a crucial role in improving infant and young child feeding practices. To evaluate the impact of activities of BFC unit (BFCU) on breastfeeding practices of infants who were hospitalized for diarrheal illness through their regular counseling, assistance and support, and motivation. Methods. In this retrospective chart analysis conducted at Dhaka Hospital of icddr,b using an electronic database, data were collected from mothers of infants younger than 6 months of age who visited the BFCU from 2011 to 2015. Results. Among a total of 3420 infants enrolled during study period, 429 (12.5%) were predominantly breastfed, 2457 (71.8%) partially breastfed, 531 (15.5%) non-breastfed, and 3 (0.1%) exclusively breastfed (EBF) at home. Through counseling of BFCU (following 24-hour recall technique), 2212 (65%) infants became EBF and 1186 (35%) failed to be EBF during discharge. Logistic regression analysis after adjusting for potential covariates, such as maternal age <18 years and receiving breast milk with other liquid at home, revealed that infants having severe underweight, maternal perception of “baby does not suck,” and “there is not enough milk” were less likely to be associated with EBF during discharge. Among 531 non-breastfed infants, 455 (85.7%) became partial breastfeeding and only 23 (4.3%) became EBF. Conclusion. Counseling of mothers even during acute illness of infants in the hospital can help promote breastfeeding. Therefore, there is great importance of robust counseling on breastfeeding practices and may help establish re-lactation of acutely ill babies.

Predictors of Mortality in Neonates and Infants Hospitalized With Sepsis or Serious Infections in Developing Countries: A Systematic Review. Front Pediatr 2018; 6:277. [PMID: 30356806 PMCID: PMC6190846 DOI: 10.3389/fped.2018.00277] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2018] [Accepted: 09/12/2018] [Indexed: 01/27/2023] Open
Abstract
Background: Neonates and infants comprise the majority of the 6 million annual deaths under 5 years of age around the world. Most of these deaths occur in low/middle income countries (LMICs) and are preventable. However, the clinical identification of neonates and infants at imminent risk of death is challenging in developing countries. Objective: To systematically review the literature on clinical risk factors for mortality in infants under 12 months of age hospitalized for sepsis or serious infections in LMICs. Methods: MEDLINE and EMBASE were systematically searched using MeSH terms through April 2017. Abstracts were independently screened by two reviewers. Subsequently, full-text articles were selected by two independent reviewers based on PICOS criteria for inclusion in the final analysis. Study data were qualitatively synthesized without quantitative pooling of data due to heterogeneity in study populations and methodology. Results: A total of 1,139 abstracts were screened, and 169 full-text articles were selected for text review. Of these, 45 articles were included in the analysis, with 21 articles featuring neonatal populations (under 28 days of age) exclusively. Most studies were from Sub-Saharan Africa and South Asia. Risk factors for mortality varied significantly according to study populations. For neonatal deaths, prematurity, low birth-weight and young age at presentation were most frequently associated with mortality. For infant deaths, malnutrition, lack of breastfeeding and low oxygen saturation were associated with mortality in the highest number of studies. Conclusions: Risk factors for mortality differ between the neonatal and young infant age groups and were also dependant on the study population. These data can serve as a starting point for the development of individualized predictive models for in-hospital and post-discharge mortality and for the development of interventions to improve outcomes among these high-risk groups.

Risk factors for mortality and effect of correct fluid prescription in children with diarrhoea and dehydration without severe acute malnutrition admitted to Kenyan hospitals: an observational, association study. THE LANCET. CHILD & ADOLESCENT HEALTH 2018; 2:516-524.

Abstract
BACKGROUND Diarrhoea causes many deaths in children younger than 5 years and identification of risk factors for death is considered a global priority. The effectiveness of currently recommended fluid management for dehydration in routine settings has also not been examined. METHODS For this observational, association study, we analysed prospective clinical data on admission, immediate treatment, and discharge of children age 1-59 months with diarrhoea and dehydration, which were routinely collected from 13 Kenyan hospitals. We analysed participants with full datasets using multivariable mixed-effects logistic regression to assess risk factors for in-hospital death and effect of correct rehydration on early mortality (within 2 days). FINDINGS Between Oct 1, 2013, and Dec 1, 2016, 8562 children with diarrhoea and dehydration were admitted to hospital and eligible for inclusion in this analysis. Overall mortality was 9% (759 of 8562 participants) and case fatality was directly correlated with severity. Most children (7184 [84%] of 8562) with diarrhoea and dehydration had at least one additional diagnosis (comorbidity). Age of 12 months or younger (adjusted odds ratio [AOR] 1·71, 95% CI 1·42-2·06), female sex (1·41, 1·19-1·66), diarrhoea duration of more than 14 days (2·10, 1·42-3·12), abnormal respiratory signs (3·62, 2·95-4·44), abnormal circulatory signs (2·29, 1·89-2·77), pallor (2·15, 1·76-2·62), use of intravenous fluid (proxy for severity; 1·68, 1·41-2·00), and abnormal neurological signs (3·07, 2·54-3·70) were independently associated with in-hospital mortality across hospitals. Signs of dehydration alone were not associated with in-hospital deaths (AOR 1·08, 0·87-1·35). Correct fluid prescription significantly reduced the risk of early mortality (within 2 days) in all subgroups: abnormal respiratory signs (AOR 1·23, 0·68-2·24), abnormal circulatory signs (0·95, 0·53-1·73), pallor (1·70, 0·95-3·02), dehydration signs only (1·50, 0·79-2·88), and abnormal neurological signs (0·86, 0·51-1·48). INTERPRETATION Children at risk of in-hospital death are those with complex presentations rather than uncomplicated dehydration, and the prescription of recommended rehydration guidelines reduces risk of death. Strategies to optimise the delivery of recommended guidance should be accompanied by studies on the management of dehydration in children with comorbidities, the vulnerability of young girls, and the delivery of immediate care.

Lancet Glob Health 2017; 5:e1235-e1248. [PMID: 29132613 PMCID: PMC5695759 DOI: 10.1016/s2214-109x(17)30392-3] [Citation(s) in RCA: 55] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2016] [Revised: 08/22/2017] [Accepted: 09/19/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Shigella infections are a leading cause of diarrhoeal death among children in low-income and middle-income countries. WHO guidelines reserve antibiotics for treating children with dysentery. Reliance on dysentery for identification and management of Shigella infection might miss an opportunity to reduce Shigella-associated morbidity and mortality. We aimed to systematically review and evaluate Shigella-associated and dysentery-associated mortality, the diagnostic value of dysentery for the identification of Shigella infection, and the efficacy of antibiotics for children with Shigella or dysentery, or both. METHODS We did three systematic reviews (for mortality, diagnostic value, and antibiotic treatment of Shigella and dysentery), and meta-analyses where appropriate, of studies in resource-limited settings. We searched MEDLINE, Embase, and LILACS database for studies published before Jan 1, 2017, in English, French, and Spanish. We included studies of human beings with diarrhoea and accepted all study-specific definitions of dysentery. For the mortality and diagnostic value searches, we excluded studies that did not include an effect estimate or data necessary to calculate this estimate. The search for treatment included only randomised controlled trials that were done after Jan 1, 1980, and assessed antibiotics in children (aged <18 years) with dysentery or laboratory-confirmed Shigella. We extracted or calculated odds ratios (ORs) and 95% CIs for relative mortality and did random-effects meta-analysis to arrive at pooled ORs. We calculated 95% CIs assuming a binomial distribution and did random-effects meta-regression of log-transformed sensitivity and specificity estimates for diagnostic value. We assessed the heterogeneity of papers included in these meta-analyses using the I2 statistic and evaluated publication bias using funnel plots. This review is registered with PROSPERO (CRD42017063896). FINDINGS 3649 papers were identified and 60 studies were included for analyses: 13 for mortality, 27 for diagnostic value, and 20 for treatment. Shigella infection was associated with mortality (pooled OR 2·8, 95% CI 1·6-4·8; p=0·000) whereas dysentery was not associated with mortality (1·3, 0·7-2·3; p=0·37). Between 1977 and 2016, dysentery identified 1·9-85·9% of confirmed Shigella infections, with sensitivity decreasing over time (p=0·04). Ten (50%) of 20 included antibiotic trials were among children with dysentery, none were placebo-controlled, and two (10%) evaluated antibiotics no longer recommended for acute infectious diarrhoea. Ciprofloxacin showed superior microbiological, but not clinical, effectiveness compared with pivmecillinam, and no superior microbiological and clinical effectiveness compared with gatifloxacin. Substantial heterogeneity was reported for meta-analyses of the Shigella-associated mortality studies (I2=78·3%) and dysentery-associated mortality studies (I2=73·2%). Too few mortality studies were identified to meaningfully test for publication bias. No evidence of publication bias was found in this analysis of studies of diagnostic value. INTERPRETATION Current WHO guidelines appear to manage dysentery effectively, but might miss opportunities to reduce mortality among children infected with Shigella who present without bloody stool. Further studies should quantify potential decreases in mortality and morbidity associated with antibiotic therapy for children with non-dysenteric Shigella infection.

BMC INTERNATIONAL HEALTH AND HUMAN RIGHTS 2014; 14:24. [PMID: 25145383 PMCID: PMC4144693 DOI: 10.1186/1472-698x-14-24] [Citation(s) in RCA: 65] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/20/2014] [Accepted: 08/13/2014] [Indexed: 12/01/2022]
Abstract
BACKGROUND In spite of global decline in under-five mortality, the goal of achieving MDG 4 still remains largely unattained in low and middle income countries as the year 2015 closes-in. To accelerate the pace of mortality decline, proven interventions with high impact need to be implemented to help achieve the goal of drastically reducing childhood mortality. This paper explores the association between socio-economic and demographic factors and under-five mortality in an impoverished region in rural northern Ghana. METHODS We used survey data on 3975 women aged 15-49 who have ever given birth. First, chi-square test was used to test the association of social, economic and demographic characteristics of mothers with the experience of under-five death. Subsequently, we ran a logistic regression model to estimate the relative association of factors that influence childhood mortality after excluding variables that were not significant at the bivariate level. RESULTS Factors that significantly predict under-five mortality included mothers' educational level, presence of co-wives, age and marital status. Mothers who have achieved primary or junior high school education were 45% less likely to experience under-five death than mothers with no formal education at all (OR = 0.55, p < 0.001). Monogamous women were 22% less likely to experience under-five deaths than mothers in polygamous marriages (OR = 0.78, p = 0.01). Similarly, mothers who were between the ages of 35 and 49 were about eleven times more likely to experience under-five deaths than those below the age of 20 years (OR = 11.44, p < 0.001). Also, women who were married had a 27% less likelihood (OR = 0.73, p = 0.01) of experiencing an under-five death than those who were single, divorced or widowed. CONCLUSION Taken independently, maternal education, age, marital status and presence of co-wives are associated with childhood mortality. The relationship of these indicators with women's autonomy, health seeking behavior, and other factors that affect child survival merit further investigation so that interventions could be designed to foster reductions in child mortality by considering the needs and welfare of women including the need for female education, autonomy and socioeconomic well-being.

Abstract
It is well established that intimate partner violence (IPV) against women adversely affects maternal morbidity and mortality. But a limited number of studies were found in the literature regarding the association between IPV and under-five child mortality. In this article, using Bangladesh Demographic and Health Survey (BDHS) 2007 data, we examined the effect of IPV on under-five child mortality. A product-limit approach was used for bivariate survival analysis, and Cox proportional hazard multiple regression models were used to investigate the effect of IPV controlling potential confounders. In bivariate analysis, the variables exposure to IPV, mother's age at birth, mother's education, residence type, division, number of children, wealth index, occupation, access to media, and decision autonomy were found to be potential risk factors for child mortality. Results indicated that women exposed to IPV were more likely to experience under-five child mortality compared with women not exposed. The unadjusted hazard ratio for IPV was 1.21 (95% confidence interval [CI] = [1.09, 1.35]) with p value < .01, whereas it was 1.16 (95% CI = [1.04, 1.29]) with p value < .01 and 1.13 (95% CI = [1.01, 1.26]) with p value < .05 in two adjusted models. These results implied that IPV against women is a problem not only for women but also for their children's survival.

Abstract
During April 2007–April 2010, surveillance physicians in adult and pediatric medicine wards of three tertiary public hospitals in Bangladesh identified patients who developed hospital-acquired diarrhea. We calculated incidence of hospital-acquired diarrhea. To identify risk factors, we compared these patients to randomly selected patients from the same wards who were admitted > 72 hours without having diarrhea. The incidence of hospital-acquired diarrhea was 4.8 cases per 1,000 patient-days. Children < 1 year of age were more likely to develop hospital-acquired diarrhea than older children. The risk of developing hospital-acquired diarrhea increased for each additional day of hospitalization beyond 72 hours, whereas exposure to antibiotics within 72 hours of admission decreased the risk. There were three deaths among case-patients; all were infants. Patients, particularly young children, are at risk for hospital-acquired diarrhea and associated deaths in Bangladeshi hospitals. Further research to identify the responsible organisms and transmission routes could inform prevention strategies.

Abstract
CONTEXT: Acute diarrhea is a common cause of hospitalization among children under 5 years of age. Knowing the prevalence and risk factors associated with the severity of acute diarrhea is essential to control morbidity and mortality. OBJECTIVE: Describe the prevalence of demographic, epidemiologic and clinical features of children under 6 years of age hospitalized for acute diarrhea, and investigate the association between these determinants and the severity of the diarrheic episode. METHOD: Retrospective, cross-sectional study, during the period from January, 2005 through December, 2008, in the municipality of Juiz de Fora, MG, Brazil. Files from 6,201 children from 0 to 6 years of age, hospitalized in two public teaching institutions (which account for 84% of all the hospitalizations in the municipality), were assessed. Acute diarrhea was defined as the presence of at least three evacuations of liquid or loose stools, within 24 hours, for a maximum period of 14 days. The patients with acute diarrhea were divided in two groups, according to disease severity, severe diarrhea being considered whenever hospitalization lasted for at least 4 days. Epidemiologic and clinical data were assessed and compared through the application of the chi-squared test and the binomial logistic regression model. RESULTS: The prevalence rate for admission due to acute diarrhea was 8.4%. The factors significantly associated with the severity of the diarrheic episode were: age under 6 months (P = 0.01, OR = 2.762); disease onset during fall (P = 0.033, OR = 1.742), presence of fever (P = 0.017, OR = 1.715) and antibiotic use during hospitalization (P = 0.000, OR = 3.872). CONCLUSIONS: Diarrhea is the third most common cause of hospitalization among children under 6 years of age in Juiz de Fora. Young age (under or equal to 6 months), fever, antibiotic use during hospitalization and disease onset during fall are risk factors associated with longer hospital stay.

Abstract
Background Diarrhea is a leading cause of morbidity and mortality globally; yet the overall burden of diarrhea in terms of duration and severity has not been quantified. As improvements in treatment lead to decreases in diarrhea mortality, it is important to understand the substantial impact of diarrhea morbidity on disability among children and adults worldwide. Methods We conducted a systematic review to generate estimates of duration and severity outcomes for individuals 0-59 mos, 5-15 yrs, and ≥ 16 yrs, and for 3 severity indexes: mild, moderate, and severe. Results We estimate that among children under-five, 64.8% of diarrheal episodes are mild, 34.7% are moderate, and 0.5% are severe. On average, mild episodes last 4.3 days, and severe episodes last 8.4 days and cause dehydration in 84.6% of cases. We estimate that among older children and adults, 95% of episodes are mild; 4.95% are moderate; and 0.05% are severe. Among individuals ≥ 16 yrs, severe episodes typically last 2.6 days and cause dehydration in 92.8% of cases. Conclusions Moderate and severe episodes constitute a substantial portion of the total envelope of diarrhea among children under-five (35.2%; about 588 million episodes). Among older children and adults, moderate and severe episodes account for a much smaller proportion of the total envelope of diarrhea (5%), but the absolute number of such episodes is noteworthy (about 21.5 million episodes among individuals ≥ 16 yrs). Hence, the global burden of diarrhea consists of significant morbidity, extending beyond episodes progressing to death.

Abstract
Diarrhoea remains one of the most common causes of childhood deaths worldwide despite the widespread use of oral rehydration solution (ORS). The vast majority of the nearly 2 million diarrhoeal deaths occurring annually in children under five years of age are in south Asia and sub-Saharan Africa. Signs of critical illness in severely dehydrated children are poorly recognised, and although considerable efforts have gone into establishing the management of diarrhoeal disease in general, there is surprisingly little understanding of the aetiology, metabolic processes and risk factors for the very high mortality associated with severe dehydrating diarrhoea (SDD). We suggest that in many resource-poor settings, the degree of fluid requirement as well as the prevalence of electrolyte disturbances are seriously under-recognised and may be contributing significantly to mortality. The heterogeneity of children with SDD renders the generic 'one size fits all' approach to fluid and electrolyte management in these critically ill children inadequate. In this review we will highlight SDD as an important target for research in resource-limited settings, and emphasise the need to re-evaluate the efficacy of prevailing intravenous fluid protocols in well conducted multi-centre interventional trials.

Abstract
BACKGROUND Infectious disease is a leading cause of morbidity and hospitalization for infants and children. During infancy, breast-feeding protects against infectious diseases, particularly respiratory infections, gastrointestinal infections, and otitis media. Little is known about the longer-term impact of breast-feeding on infectious disease in children. METHODS We investigated the relationship between infant feeding and childhood hospitalizations from respiratory and gastrointestinal infections in a population-based birth cohort of 8327 children born in 1997 and followed for 8 years. The main outcomes were public hospital admissions for respiratory infections, gastrointestinal infections, and all infectious diseases. Cox regression was used to assess time to first hospitalization. RESULTS Breast-feeding only (no formula-feeding) for 3 or more months was associated with a lower risk of hospital admission in the first 6 months of life for respiratory infections (hazard ratio = 0.64 [95% confidence interval = 0.42-0.97]), gastrointestinal infections (0.51 [0.25-1.05]), and any infection (0.61 [0.44-0.85]), adjusted for sex, type of hospital at birth, and household income. Partial breast-feeding (both breast-feeding and formula-feeding) in the first 3 months also reduced hospitalizations from infections but with smaller effect sizes. Beyond 6 months of age, there was no association between breast-feeding status at 3 months and hospitalization for infectious disease. CONCLUSIONS Giving breast milk and no formula for at least 3 months substantially reduced hospital admissions for many infectious diseases in the first 6 months of life, when children are most vulnerable.

Abstract
OBJECTIVES To identify clinical and laboratory predictors of bacteremia in infants with diarrhea and systemic inflammatory response syndrome and to analyze their outcome. STUDY DESIGN Retrospective, case-control study. SETTING The Special Care Ward of the Dhaka Hospital of the International Centre for Diarrheal Disease Research, Bangladesh, Dhaka, Bangladesh. PATIENTS All the infants (n = 90) admitted to the Special Care Ward between May 2005 and April 2006 who had a blood culture, full peripheral blood count, and serum C-reactive protein performed were included in the study. Infant with systemic inflammatory response syndrome with confirmed bacteremia (n = 18) constituted cases, and those with systemic inflammatory response syndrome but negative blood culture (n = 72) constituted the controls. RESULTS The following features were analyzed by comparing the two groups: absent or uncountable peripheral pulses, hypothermia, sclerema, altered mental status, white blood cell count, serum C-reactive protein, total protein concentrations, and outcome. The case-fatality rate was significantly higher among bacteremic infants compared with those without bacteremia (33% vs. 6%, p < .01). In the univariate model, sclerema (56% vs. 28%, p = .05), hyperglycemia (28% vs. 6%, p < .01), immature neutrophils [3.5 (00, 6.5) vs. 0.0 (0.0, 3.25); p = .02], higher C-reactive protein [2.7 (1.2, 7.4) vs. 1.8 (0.5, 4.2); p = .02], and lower serum total protein (51.1 +/- 14.1 vs. 57.6 +/- 12.2; p = .05) were identified as potential predictors of bacteremia. However, in the logistic regression analysis, after adjusting for confounders, only hypothermia (odds ratio = 6.4, 95% confidence Interval, 1.6-25.9; p = .01) and absent or uncountable peripheral pulse (odds ratio, 12.4, 95% confidence interval, 1.9-83.4; p < .01) remained significant independent predictors of bacteremia. CONCLUSIONS Our data suggest that, in infants presenting with diarrhea and systemic inflammatory response syndrome, coexistence of hypothermia and absent or uncountable peripheral pulse is strongly associated with bacteremia. Bacteremia in this patient group is associated with high case-fatality rates.

Abstract
BACKGROUND Zinc is lost during diarrheal diseases, and zinc deficiency induces intestinal morphology-altering inflammatory responses that zinc supplementation can correct. OBJECTIVE We assessed the in vivo effect of zinc supplementation on systemic and mucosal responses in mildly to moderately malnourished (defined as <-1 but >-2 and <-2 but >-3 weight-for-height z scores, respectively, based on the National Center for Health Statistics growth reference) children with shigellosis. DESIGN A double-blind placebo-controlled trial was conducted in Shigella flexneri-infected children aged 12-59 mo. Daily for 14 d, elemental zinc (20 mg) and multivitamins (vitamins A and D, thiamine, riboflavin, and nicotinamide) plus calcium were given at twice the US recommended dietary allowance to the zinc group (n=28), and multivitamins plus calcium were given to the control group (n=28). All subjects received standard antibiotic therapy. RESULTS There was no significant interaction between zinc supplementation and time, but zinc supplementation showed a significant effect on serum zinc concentrations. With a >or=4-fold increase in serum shigellacidal antibody titers from baseline used as the cutoff, the proportion of children with shigellacidal antibody response was greater in the zinc group than in the control group (P<0.03). There was a significant (P=0.02) treatment x time interaction for the proportions of circulating CD20+ and CD20+CD38+ cells, which were higher on day 7 in the zinc group than in the control group (P<0.007). No effect was seen on histopathologic features or the expression of innate and inflammatory mediators in the rectum. CONCLUSION Adjunct therapy with zinc during acute shigellosis significantly improved seroconversion to shigellacidal antibody response and increased the proportions of circulating B lymphocytes and plasma cells.

Abstract
The aim of this study was to examine the effect of demographic, socioeconomic, environmental, maternal reproductive, dietary, and nutritional variables on diarrhea risk and prognosis using a hierarchical framework. A case-control study of children aged 0-23 months in Greater Metropolitan Porto Alegre was conducted during the peak season for diarrhea in 1987-1988. Three groups were investigated, with 192 children each. The first group included hospitalized children with an episode of acute diarrhea complicated by moderate to severe dehydration. The second group included children with acute mild diarrhea without signs of dehydration who were identified in the same neighborhood as hospitalized cases. The third group consisted of controls without diarrhea. Mothers were interviewed by trained interviewers using a standardized questionnaire. Data analysis included a hierarchical approach to control for confounding, using conditional logistic regression. Comparison of the three groups aimed to identify risk factors for diarrhea complicated by dehydration, prognostic factors for dehydration, and risk factors for mild diarrhea. Low birth weight, stunting, and lack or breastfeeding acted simultaneously as risk and prognostic factors for diarrhea.

Abstract
It is important to determine the specific factors for diarrheal deaths in infants & young children to enable the intervention and reduce the mortality rates. This study aimed to identify these factors in children under five years of age, hospitalized with diarrheal complaints. Four hundred diarrheal children were included in the study. Twenty-seven (6.75%) of them died and 373 (93.25%) survived. The nutritional status of the patients was determined using weight for height for age as percentage of Harward Standard. It was found that severe malnutrition (p = 0.000 for weight for height ration < 70% and p = 0.036 for height for age < 85%), co-existent sepsis (p = 0.000), shigella infection (p = 0.0014), hypoalbuminemia (p = 0.0000), hypoglycemia (p = 0.0002), hyponatremia (p = 0.016), hypokalemia (p = 0.0041) and metabolic acidosis (p = 0.0069 for pH < 7.35 and p = 0.000 for HCO3 < 20 moL/l) were significant risk factors for diarrheal deaths in the univariate analysis. In the multivariate analysis, young age (under 6 months of age) ¿Odds ratio (OR) 10.49, 95% confidence interval (CI) 1.75, 62.75)¿, moderate or severe dehydration (OR 8.17, 95% CI 1.53, 43.67), severe malnutrition (OR 0.04, 95% CI 0.00, 0.22 of weight for height < 70% and OR 0.03, 95% CI 0.00, 0.36 for height for age < 85%), co-existent sepsis (OR 37.26, 95% CI 6.94, 200.06), shigella infection (OR 23.01, 95% CI 3.08, 171.98), hypoalbuminemia (OR 0.11, 95% CI 0.02, 0.54), metabolic acidosis (OR 0.03, 95% CI 0.00, 0.33 of HCO3 < 20 mMol/L) were significant risk factors. It is concluded that, in addition to electrolyte and fluid treatments, prevention of malnutrition, continuation of feeding which lessens weight loss and may prevent fatal hypoglycemia, and early detection and treatment of probable sepsis are important in reducing diarrheal deaths.

Abstract
Rotavirus infections are the most common cause of gastroenteritis among children younger than 3 years of age and are associated with sporadic outbreaks of diarrhea in elderly and immunocompromised patients. Oral rehydration solutions (ORS) are formulated to correct dehydration and acidosis. Currently, ORS do not promote intestinal healing; however, investigators are examining the role of nutrition in promoting intestinal healing. This article reviews the composition of several ORS in human medicine and summarizes our current knowledge of the nutritional treatment of rotavirus diarrhea and intestinal healing.

Abstract
Increased intestinal fluid secretion is a protective host response after enteric infection with invasive bacteria that is initiated within hours after infection, and is mediated by prostaglandin H synthase (PGHS) products in animal models of infection. Intestinal epithelial cells are the first host cells to become infected with invasive bacteria, which enter and pass through these cells to initiate mucosal, and ultimately systemic, infection. The present studies characterized the role of intestinal epithelial cells in the host secretory response after infection with invasive bacteria. Infection of cultured human intestinal epithelial cell lines with invasive bacteria, but not noninvasive bacteria, is shown to induce the expression of one of the rate-limiting enzymes for prostaglandin formation, PGHS-2, and the production of PGE2 and PGF2alpha. Furthermore, increased PGHS-2 expression was observed in intestinal epithelial cells in vivo after infection with invasive bacteria, using a human intestinal xenograft model in SCID mice. In support of the physiologic importance of epithelial PGHS-2 expression, supernatants from bacteria-infected intestinal epithelial cells were shown to increase chloride secretion in an in vitro model using polarized epithelial cells, and this activity was accounted for by PGE2. These studies define a novel autocrine/paracrine function of mediators produced by intestinal epithelial cells in the rapid induction of increased fluid secretion in response to intestinal infection with invasive bacteria.
