Obesity has become a global public health problem, and its relationship with gastrointestinal diseases has become a major concern. The visceral adiposity index (VAI) is a novel index to assess the distribution and content of visceral fat, and this study aimed to investigate the association between VAI and bowel habits (chronic diarrhea, chronic constipation) and inflammatory bowel disease (IBD). The 2005-2010 National Health and Nutrition Examination Survey (NHANES) dataset was used for the cross-sectional survey. Bowel habits and IBD were defined by self-report. Multiple logistic regression models were used to test the linear association of VAI with bowel habits and IBD. Fitted smoothed curves and threshold effects analyses were used to characterize nonlinear relationships. This cross-sectional study included 10,391 adults (≥ 20 years). After adjusting for covariates, there was a significant negative association between VAI and chronic constipation (OR [95% CI]: 0.97 [0.95, 1.00]) but no significant association with IBD (OR [95% CI]: 0.97 [0.87, 1.07]). Additionally, there was a nonlinear association between VAI and chronic diarrhea with a breakpoint of 3.08, with a positive correlation between the two on the left side of the breakpoint and no statistical significance on the right side. Subgroup analyses and interaction tests showed that maintaining sleep health was associated with a low risk of chronic constipation. Elevated VAI levels were negatively associated with chronic constipation, and elevated levels were positively associated with chronic diarrhea at VAI < 3.08. This reminds us that maintaining moderate levels of visceral fat may prevent the onset of chronic constipation and circumvent the risk of chronic diarrhea. Notably, maintaining healthy sleep may play a positive role in reducing chronic constipation., (© 2024. The Author(s).)

Background: Approximately 12% of all diarrhoeal episodes last for 7-13 days. As such, they are termed prolonged diarrhoea, and are associated with over two-thirds of all diarrhoeal deaths. Due to a lack of robust data, we aimed to evaluate a comparative background characteristics of young children with acute and prolonged diarrhoea, and their outcomes at day 90 follow-up., Methods: We performed a secondary analysis of data from the Antibiotics for Children with Diarrhea (ABCD) trial. Children aged 2-23 months were enrolled between July 2017 and July 2019 from seven Asian and sub-Saharan African countries. For this analysis, we divide diarrhoea into two categories: acute diarrhoea (duration <7 days) and prolonged diarrhoea (duration ≥7-13 days). We used logistic regression to observe baseline crude and adjusted associations and linear regression to compare post-discharge outcomes., Results: We analysed data on 8266 children, of whom 756 (9%) had prolonged diarrhoea and 7510 (91%) had acute diarrhoea. Pakistan had the highest proportion of children with prolonged diarrhoea (n/N = 178/1132, 16%), while Tanzania had the lowest (n/N = 12/1200, 1%). From an analysis that adjusted for sex, breastfeeding, nutritional status, clinical presentation, housing, water supply, sanitation, and country, we observed that presentation at a health facility with prolonged diarrhoea was associated with low age (2-12 months) (adjusted odds ratio (aOR) = 1.25; 95% confidence interval (CI) = 1.02, 1.53; P = 0.028), presence of three or more under-five children in the family (aOR = 1.54; 95% CI = 1.26, 1.87; P < 0.001), maternal illiteracy (aOR = 1.45; 95% CI = 1.21, 1.74, P < 0.001), moderate underweight (aOR = 1.25; 95% CI = 1.01, 1.55; P = 0.042) and pathogen (Campylobacter) (aOR = 1.27; 95% CI = 1.12, 1.44; P < 0.001). At day 90 follow-up, children with prolonged diarrhoea had significantly lower weight-for-age z-score compared to children with acute diarrhoea (-1.62, standard deviation (SD) = 1.11 vs -1.52, SD = 1.20; P = 0.032), as well as significantly higher frequency of hospital admission (6.1% vs 4.5%; P = 0.042)., Conclusions: Prolonged diarrhoea was more common in children of younger age, those who were moderately underweight, those with Campylobacter in stool, those with three or more under-five children in a family, and those with illiterate mothers compared to those who had acute diarrhoea. Children with prolonged diarrhoea more often required hospitalisation during the three-month follow-up period compared to their counterparts., Competing Interests: Disclosure of interests: The authors completed the ICMJE Disclosure of Interest Form (available upon request from the corresponding author) and disclose no relevant interests., (Copyright © 2024 by the Journal of Global Health.

Recent advances in clinical prediction for diarrhoeal aetiology in low- and middle-income countries have revealed that the addition of weather data to clinical data improves predictive performance. However, the optimal source of weather data remains unclear. We aim to compare the use of model estimated satellite- and ground-based observational data with weather station directly observed data for the prediction of aetiology of diarrhoea. We used clinical and etiological data from a large multi-centre study of children with moderate to severe diarrhoea cases to compare their predictive performances. We show that the two sources of weather conditions perform similarly in most locations. We conclude that while model estimated data is a viable, scalable tool for public health interventions and disease prediction, given its ease of access, directly observed weather station data is likely adequate for the prediction of diarrhoeal aetiology in children in low- and middle-income countries.

Escherichia albertii is an emerging foodborne enteropathogen associated with infectious diarrhoea in humans. In February 2023, an outbreak of acute gastroenteric cases was reported in a junior high school located in Hangzhou, Zhejiang province, China. Twenty-two investigated patients presented diarrhoea (22/22, 100%), abdominal pain (21/22, 95.5%), nausea (6/22, 27.3%), and vomiting (3/22, 13.6%). E. albertii strains were successfully isolated from anal swabs collected from six patients. Each isolate was classified as sequence type ST2686, harboured eae -β gene, and carried both cdtB -I and cdtB -II subtypes, being serotyped as EAOg32:EAHg4 serotype. A comprehensive whole-genome phylogenetic analysis revealed that the six isolates formed a distinct cluster, separate from other strains. These isolates exhibited minimal genetic variation, differing from one another by 0 to 1 single nucleotide polymorphism, suggesting a common origin from a single clone. To the best of our knowledge, this represented the first reported outbreak of gastroenteritis attributed to E. albertii outside of Japan on a global scale.

Background and Aims: Diarrhoea is one of the deadliest diseases and causing death among children in India, but no systematic attempt is made to understand it especially its control using oral rehydration salts (ORS). It is well known that use of ORS and Zinc have been effective in containing diarrhoea among children. An attempt is made using large scale national data set in India to understand use of ORS and Zinc to control diarrhoea and their associated factors among diarrhoeal children under five in India., Methods: Publicly available most recent cross-sectional National Family Health Survey data in India was used for the study. The multi-stage cluster sampling design was used with 2011 Census of India as a sampling frame. Households were selected using a Systematic Random Sampling design from selected primary sampling units in rural and urban clusters. From the selected households, the eligible children were those who suffered from diarrhoea in the two weeks preceding the survey and were less than 5 years old. Using this criterion, out of 232,920 children in the survey of less than five years, 16,213 sample diarrheal children found to be available for the study. Both descriptive and inferential statistical techniques were used to analyse the data., Results: Across India, 61% and 31% of the children were given ORS and Zinc respectively. However, combined ORS + Zinc treatment was only around 24%. The treatment of ORS, Zinc, and combined ORS + Zinc supplementations were significantly higher among younger children, children of 24-35 age group mothers, children from rich wealth index groups, belong to Hindu religion and general caste compared to their counterparts. The logistic regression results showed that consumption of ORS among diarrhoeal children under five years of age depends upon size of a child at birth. For instance, diarrheal children who were very small size at birth compared to very large at birth, had 39% lower odds of consuming ORS (AOR = 0.61; CI 0.48, 0.78; p<0.001). Another important variable is place of first treatment sought for diarrheal children. That is children who first sought treatment in private hospital compared to government hospital had 52% lower odds of ORS consumption. The logistic regression adjusted AORs are similar with Zinc and ORS + Zinc supplementations., Conclusions: To improve the coverage and management of childhood diarrhoea in India, planning activities should focus not only on distribution, and increasing knowledge of ORS preparation especially for urban slum residents and rural disadvantaged groups through demonstration. There should be also proper focus on providing ongoing pathways to ensure proper supply chains., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Halli et al.

Objectives: To highlight the importance of neglected Entamoeba histolytica ( E. histolytica ) infections in the geriatric age group, which is an increasing proportion of the world's population., Methods: This study was carried out between January 2022 and December 2023 at Van Yüzüncü Yıl University, Faculty of Medicine, Parasitology Laboratory, Van, Turkey. The study included 96 geriatric patients with diarrhea (geriatric group). Two different control groups (CGs) were also included in the study, comprising 92 patients aged 18-64 years with diarrhea as CG1 and 50 geriatric individuals without diarrhea and other gastrointestinal complaints as CG2. Samples were analysed macroscopically and then evaluated by microscopic, enzyme-linked immunoassay, and polymerase chain reaction., Results: This study detected E. histolytica in 31.3% of the geriatric group and 14.1% of the patients in CG1 ( p =0.004). Entamoeba histolytica positivity was not detected in CG2. According to the multiple correspondence analysis, there was a close association between E. histolytica positivity and bloody diarrhea and mucous diarrhea in the geriatric patients. It was also determined that E. histolytica can cause abdominal pain, abdominal distension, and epigastric tenderness in geriatric patients., Conclusion: Both the risk of E. histolytica infection and the pathogenicity of the infection increase in geriatric individuals. Therefore, it was concluded that amoebiasis is a serious health problem in the geriatric population and should not be neglected., (Copyright: © Saudi Medical Journal.)

Campylobacteriosis and antimicrobial resistance (AMR) are global public health concerns. Africa is estimated to have the world's highest incidence of campylobacteriosis and a relatively high prevalence of AMR in Campylobacter spp. from humans and animals. Few studies have compared Campylobacter spp. isolated from humans and poultry in Africa using whole-genome sequencing and antimicrobial susceptibility testing. We explored the population structure and AMR of 178 Campylobacter isolates from East Africa, 81 from patients with diarrhea in Kenya and 97 from 56 poultry samples in Tanzania, collected during 2006-2017. Sequence type diversity was high in both poultry and human isolates, with some sequence types in common. The estimated prevalence of multidrug resistance, defined as resistance to >3 antimicrobial classes, was higher in poultry isolates (40.9%, 95% credible interval 23.6%-59.4%) than in human isolates (2.5%, 95% credible interval 0.3%-6.8%), underlining the importance of antimicrobial stewardship in livestock systems.

Diarrheal disease is a leading cause of death in children in low- and moderate-income countries. Fresh produce, including fruits and vegetables, may harbor diarrheal disease-causing bacteria including strains of Salmonella enterica and Escherichia coli. This study aimed to determine the prevalence and antibiotic resistance profiles of S. enterica and E. coli isolated from produce samples (n = 207) obtained from retail markets in northern Botswana in Chobe District of Botswana in 2022. Samples were enriched in the appropriate selective media: Brilliant Green Bile Broth for E. coli and Rappaport Vassiliadis Broth for S. enterica. E. coli were confirmed by PCR detecting the phoA gene, and classified as potentially pathogenic through screening for the eae, stx, and stx2 and estIb genes. S. enterica isolates were confirmed using invA primers. Isolates were evaluated for resistance to ampicillin, amoxicillin-clavulanic acid, chloramphenicol, cefotaxime, doxycycline, streptomycin, sulfamethoxazole, and tetracycline antibiotic using the Kirby-Bauer Disk Diffusion method. E. coli was isolated from 15.5% of produce samples (n = 207). The gene eae was detected from 1.5% of samples, while stx1, stx2, and estIb were not detected. Resistance to one or more antibiotics was common (72%) with the majority of the resistant E. coli (n = 32) isolated from fruits (22%) and greens (18%) compared to other types of vegetables. Multidrug resistance (MDR, resistant to 3 or more antibiotics) was identified in 18% of samples. S. enterica was isolated from 3.4% of produce samples (7, n = 207). Resistance was uncommon among the S. enterica isolates (1/7). Overall prevalence of diarrheagenic S. enterica and E. coli was low; however, their presence and that of MDR E. coli in foods commonly consumed raw increases the risk to vulnerable populations. Strategies to reduce contamination of fresh produce and public education on washing and cooking some types of produce may be useful to reduce disease., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objectives: Globally, billions of people do not have access to safely managed drinking water and sanitation services. Interventions to improve drinking water, sanitation and hygiene could reduce the incidence of diarrhoea in low- and middle-income countries. This study aimed to investigate the association between these services and the incidence of diarrhoea., Study Design: Worldwide, ecological observational study, utilising cross-sectional data., Methods: Data from the Global Burden of Disease Study 2019 and World Bank were used in this study. Diarrhoeal disease episodes were defined as three or more loose bowel movements within 24 h. Estimated Annual Percentage Change was used to quantify trends in disease incidence over a specific time interval. Quasi-Poisson Generalised Linear Model was introduced to analyse the influence of basic drinking water and sanitation services on the incidence of diarrhoea. Subgroup analyses were carried out to determine potential variations in the incidence of diarrhoeal diseases according to sex, age and sociodemographic index (SDI) region., Results: Between 2000 and 2019, the incidence rate of global diarrhoea remained consistent, with regional variations linked to SDIs. A 1% increase in access to basic drinking water was associated with a 0.41% (95% confidence interval [CI], 0.33%-0.50%) increase in the age-standardised incidence rate of diarrhoea; meanwhile, a 1% increase in sanitation service usage was associated with a 0.47% (95% CI, 0.40%-0.54%) reduction in the age-standardised incidence rate of diarrhoea. The correlation differed across SDI regions. The use of safely managed drinking water was associated with a reduction in diarrhoeal disease rates, but the effect was non-significant in High SDI regions. Higher diarrhoeal disease incidence was seen in younger and older populations. Individuals in the age groups 55-59 years and 10-14 years showed the greatest association of water service usage with diarrhoea, while an increase in sanitation service usage was related to decreased diarrhoea rates in most age groups, excluding children aged 5-14 years., Conclusions: Emphasising initiatives to enhance water quality, elevate the standards of drinking water safety management, and strengthening related infrastructure development in global health policies and development plans could have a positive impact on overall global health. Such comprehensive interventions have the potential to not only prevent waterborne diseases but also elevate the general health status of societies worldwide., (Copyright © 2024 The Author(s).

Cryptosporidium spp. is a diarrhea-causing protozoan. Immunocompromised patients may develop severe and persistent clinical forms. Here we describe the characteristics of patients with an underlying disease associated with immunosuppression (DAI) and Cryptosporidium spp. infection seen at a referral children's hospital in Argentina between 2018 and 2023. Demographic data, DAI, diarrhea characteristics, and co-infections were analyzed. A total of 30 patients with DAI and cryptosporidiosis were included. Most of them had undergone a solid organ transplant, had a hematologic neoplasm, or primary immunodeficiency. Persistent diarrhea was observed in 18 patients at the time of diagnosis. Co-infections were recorded in 6 patients. Cryptosporidiosis should be considered in the differential diagnosis of acute or persistent diarrhea in children with different types of DAI, such as solid organ transplant, hematologic neoplasms, and primary immunodeficiencies., (Sociedad Argentina de Pediatría.)

Introduction: Bile acid diarrhea (BAD) is an underrecognized and socially debilitating disease caused by high concentrations of bile acids in the colon. Bile acids directly and indirectly promote carcinogenesis. In this article, we investigated whether individuals with BAD have an increased risk of gastrointestinal (GI) cancers., Methods: By using the Danish health registries, adult individuals with BAD were identified by International Classification of Diseases 10th revision code K90.8 or referral to the diagnostic ⁷⁵selenium-homotaurocholic acid test followed by prescription of a bile acid sequestrant within 365 days (n = 5,245). Age- and sex-matched individuals without BAD were included for comparison (n = 52,450). We analyzed the cumulative incidence of GI cancers after BAD diagnosis and the odds ratios (ORs) of GI cancer 8 and 15 years before BAD diagnosis/matching., Results: Cumulative incidence of GI cancer 6 years after BAD diagnosis/matching was 1.6% in the BAD group and 1.1% in controls ( P = 0.01). The ORs of total GI cancer 8 and 15 years before BAD diagnosis were 6.16 (5.08-7.48) and 5.19 (4.28-6.29), respectively. Furthermore, 47 individuals with BAD (0.9%) and 250 (0.5%) controls died of GI cancer., Discussion: This nationwide cohort study indicates an association between BAD and GI cancers. We found both a higher incidence of GI cancer after BAD diagnosis compared with controls and increased OR of GI cancer before BAD diagnosis. Bearing in mind the underdiagnosis of BAD, the delay of BAD diagnosis, and the carcinogenic effect of bile acids, these findings warrant further investigations of the risk of GI cancer in individuals with BAD., (Copyright © 2024 The Author(s).

Background: Diarrheal disease is still the leading cause of morbidity and mortality in children, despite significant progress in diarrhea interventions. Zoonotic transmission is the main cause of the emergence and re-emergence of diseases. Domestic animals are often close to humans, particularly in resource-poor countries. Despite evidence of environmental contamination, there have been limited studies conducted to examine the association between domestic animal exposure and diarrheal disease in low- and middle-income countries (LMIC). Therefore, this systematic review and meta-analysis examines the association between domestic animal exposure and diarrheal disease in children under five years of age in LMIC., Methods: The search strategy followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for the reporting of systematic reviews. All appropriate databases were searched to find relevant articles. Research studies were selected for review if they reported an outcome variable that measured diarrhea and exposure variables of any domestic animals. A data extraction form was used to extract information from each study. The quality of the individual articles was assessed using the Joanna Briggs Institute (JBI's) critical appraisal tools. Publication bias was checked using a funnel plot, Egger's regression test, and Begg's test. The heterogeneity of studies was checked using the Galbraith plot and the I-squared test. A sensitivity analysis was conducted, and a meta-analysis was conducted using STATA 17., Results: After reviewing 113 articles, 11 articles fulfilled the inclusion criteria hence considered for meta-analysis. The finding of these 11 studies revealed that study participants who had animal exposure had 1.95 higher odds of diarrhea as compared to participants who hadn't animal exposure (OR: 1.95, 95%CI: 1.25, 2.66)., Conclusions and Recommendations: This study reported that diarrheal disease was associated with study subjects who had domestic animal exposure. Therefore, more comprehensive research is needed on specific behaviors and interventions surrounding animal husbandry that may affect the transmission of pathogens between animals and humans; this would facilitate the design and implementation of measures to reduce animal exposure in the domestic environment., (© 2024.

Background: Noroviruses (NoVs) are the leading cause of diarrheal disease among all age groups worldwide, with an increased burden in developing countries. As there is no surveillance, epidemiological data is limited in Ethiopia. Hence, this study aimed to investigate the prevalence and associated factors of NoV infection among patients with diarrhea in the Amhara National Regional State, Ethiopia., Methods: A prospective health facility-based cross-sectional study was conducted from May 2021 to November 2021. A total of 550 study participants of all age groups with symptoms of diarrhea were proportionately assigned to the four study areas, area with three health facilities. Study participants were systematically sampled in each health facility. A fecal sample from each case was collected. The RNA was extracted and tested for NoV by one-step RT-PCR. Sociodemographic and other variables were gathered using a pre-tested questionnaire. A descriptive analysis was performed. Both binary and multiple logistic regressions were utilized to identify factors associated with NoV infection. Variables with a p-value < 0.05 in the final model were considered statistically significant., Results: Five hundred nineteen out of 550 samples were analyzed (94.4% response rate). The overall prevalence of NoV was 8.9% (46/519). The positivity rates were higher among the elderly (33.3%) and under-5 children (12.5%). Both genogroup I and genogroup II (GII) were identified, with GII being the predominant, at 82.6% (38/46). Of all participants, only 20% reported a history of vomiting. Norovirus infection was more prevalent among participants from Debre Tabor (AOR = 4, 95%CI: 1.2-14) and Bahir Dar areas (AOR = 3.6, 95%CI: 1.04-11) compared to Debre Markos. Additionally, older adults (AOR = 7, 95% CI: 2-24) and under-5 children (AOR = 3.5, 95% CI: 2.8-12) were disproportionately affected compared to adults. The previous history of diarrhea (AOR = 3.6, 95% CI: 1.7-7) was a significant factor contributing to NoV infections. Moreover, the odds of NoV infection were higher among individuals with a high frequency of diarrhea (AOR = 15.3, 95%CI: 7.6-43) and vomiting (AOR = 3.5, 95%CI: 1.5-8)., Conclusions: The prevalence of NoV was considerably high, with the predominance of NoV-GII. The positivity rate was higher among the extreme age groups and varied across the study areas. To obtain a comprehensive understanding of the virus`s epidemiology and its genetic diversity, further research is warranted., (© 2024. The Author(s).)

Background: A significant portion of the Muslim community participates in the Arba'een pilgrimage, with participant numbers increasing each year. There have been relatively few studies on the health of Arba'een Mass gathering (MG). Researching the prevalence and distribution of diseases among Arba'een pilgrims is essential to recognize any outbreaks and take timely responses to contain them. The current study aimed to identify exposures and risk factors for diarrheal disease in pilgrims who referred to the clinics located in Iraq among the Arba'een MG in 2023., Methods: This case-control study randomly selected 200 outpatients (100 cases and 100 controls) who were referred to Iraq clinics. Cases were patients with gastrointestinal symptoms (diarrhea), while controls were randomly selected from unaffected pilgrims at the same time for the cases. The study groups matched for age, and sex. Face-to-face interviews using a reliable field based checklist of the Center for Disease Control and Prevention of Iran's Ministry of Health to collect potential exposures and risk factors for diarrheal disease. Multiple logistic regression was used to estimate the crude and adjusted odds ratio (AOR) for the risk of diarrhea with a 95% confidence interval (CI)., Results: The average age of the participants was 38.6 years. Diarrhea in 100% and fever in 81% were the most common clinical symptoms in patients. Having underlying diseases was not associated with an increased risk of diarrhea disease (P > 0.05). Regarding risk factors for diarrheal, the final analysis after adjusting for potential confounders indicated that consumption of insanitary (unpackaged) drinking water (AOR = 1.95; 95% CI: 1.05-3.6; P = 0.024), inappropriate hand washing (AOR = 3.82; 95% CI: 1.7-8.6; P = 0.001), ritual foods (AOR = 2.56; 95% CI: 1.3-5.2; P = 0.004), and public toilets (AOR = 1.46; 95% CI: 1.04-4.3; P = 0.038) were significantly increased the likelihood of diarrheal disease., Conclusions: Contamination of water sources, food, inadequate and poor hand washing were the most common sources of diarrheal diseases among Arba'een pilgrims. The results indicate that the potential occurrence of outbreaks, especially water- and foodborne diseases, threatens participants in the Arba'een MG. It is recommended to provide risk assessment, improve pilgrims' awareness, pre-and post-screening, vaccination, compliance with personal hygiene, improvement of the environment, provision of sanitary water and food sources and hygienic disposal of sewage, laboratory diagnosis to identify the common types of pathogens in Arba'een MG., (© 2024.

Dhaka is one of the world's densely populated cities and faces significant public health challenges including high burden of diarrhoeal diseases. Climate change is intensifying existing environmental problems including urban heat island effect and poor water quality. While numerous epidemiological studies have linked meteorological factors to diarrhoeal diseases in Bangladesh, assessment of the impacts of future climate change on diarrhoeal diseases is scarce. We provide the assessment of climate change impacts on diarrhoeal disease in Dhaka and project future health risks under climate change scenarios. About 3 million acute diarrhoea cases presenting to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research Bangladesh (icddr,b) during 1981-2010 were linked to daily temperature, rainfall and humidity and association investigated using time series adapted negative binomial regression models employing constrained distributed lag linear models. The findings were applied to climate projections to estimate future risks of diarrhoea under various global warming scenarios. There was a significantly raised risk of diarrhoea hospitalisation in all ages with daily mean temperature (RR: 3.4, 95% CI: 3.0-3.7) after controlling for the confounding effects of heavy rainfall, humidity, autocorrelations, day of the week effect, long-term time, and seasonal trends. Using the incidence rate ratio (IRR) of 1.034, temperature increases based on the global warming targets of 1.5-2°C could result in an increase of diarrhoea hospitalisations by 4.5-7.4% in all age groups by the 2100s. These effects were more pronounced among <5 children where the predicted temperature increases could raise diarrhoea hospitalisation by 5.7% - 9.4%. Diarrhoea hospitalisation will increase significantly in Dhaka even if the global warming targets adopted by the Paris Agreement is reached. This underscores the importance of preparing the city for management and prevention of diarrhoeal diseases., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Haque et al.

Background: In developing countries like Bangladesh, under-five children are mostly experiencing and suffering from common diseases like fever, cough, diarrhea, and acute respiratory infections (ARI). To mitigate these problems, it's crucial to spot prevalent areas and take proper action. This study investigates the spatial distribution and associated factors of prevalent childhood illnesses across Bangladesh., Methods and Findings: This research comprised 8,306 children's information from the Bangladesh Demographic and Health Survey (BDHS) 2017-18. We performed chi-square, t-tests, binary logistic regression and spatial analyses in this work. BDHS survey data and GPS data were aggregated to identify common childhood illnesses among under-five children. Moran's index first mapped childhood illnesses. Afterward, Getis-Ord Gi* discovered hot and cold spots for illnesses. However, Kriging interpolation predicted child illnesses in unsampled areas. Here, 33.2% (CI: 32.2-34.3), 36% (CI: 35-37.1), 4.7% (CI: 4.3-5.2), and 12.9% (CI: 12.2-13.6) of children under five had fever, cough, diarrhea, and ARI, respectively. In the fortnight before to the survey, 47.3% (CI: 46.2-48.3) of under-5 children were ill. Common childhood illnesses are associated with children's (age, underweight status, etc.), mothers' (age, education, etc.), and household factors (residency, wealth index, etc.). Underweight status is associated with fever, cough and at least one disease. The unsampled north-western and south-western areas of Bangladesh had a higher prevalence of fever, cough, ARI and at least one common disease. Cough was most common in the central-northern region; fever was most common in the lower southern region; and ARI was most common in Bangladesh's south-east. Childhood diseases were more prevalent in Bangladesh's central-northern and southern regions., Conclusions: Our research demonstrates the regional clustering of common childhood diseases in Bangladesh. Policymakers should focus on these higher-prevalence regions, and the necessary preventive measures should be taken immediately., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Islam et al.

The diarrheagenic Escherichia coli (DEC) is the major cause of diarrheal diseases in Africa, including Ethiopia. However, the genetic diversity of E. coli pathotypes found in Ethiopia has not been studied well. This study aimed to characterize potential DEC belonging to enteropathogenic (EPEC), Shiga toxin-producing (STEC), enteroaggregative (EAEC), enterotoxigenic (ETEC), and enteroinvasive (EIEC) E. coli pathotypes from stool specimens of patients attending primary healthcare units ( n = 260) in Addis Ababa and Hossana using whole-genome sequencing. Real-time PCR assays were used to identify DEC isolates belonging to EPEC, STEC, EAEC, ETEC, and EIEC pathotypes, which were then subjected to whole-genome sequencing on the Illumina platform. Twenty-four whole-genome nucleotide sequences of DEC strains with good enough quality were analyzed for virulence-associated genes (VAGs), antibiotic resistance genes (ARGs), phylogenetic groups, serogroups, and sequence types. The majority (62.5%) of DEC isolates belonged to the phylogenetic group B1. The identified DEC isolates belonged to 21 different serogroups and 17 different sequence types. All tested DEC isolates carried multiple VAGs and ARGs. The findings highlight the high diversity in the population structure of the studied DEC isolates, which is important for designing targeted interventions to reduce the diarrheal burden in Ethiopia.

Objective: There are limited data in Ethiopia on common childhood illnesses. We aimed to measure the incidence and risk factors of common childhood illnesses in rural parts of southern Ethiopia., Design: A community-based cohort study., Participants and Study Setting: A total of 903 children of 5 years or younger were included between July 2017 and January 2018. We randomly selected households from three administrative units (kebeles) in Wonago district in Ethiopia., Outcomes: Data on incidence of illnesses were collected by interviewing the mothers of the children every second week, in 6 months. Incidence densities per child-week of observation were calculated, and predictors or recurrent illnesses were evaluated in multilevel Poisson regression models., Results: Out of 903 children, 882 were included (97.6%). At least one illness was experienced among 87.3% of the children. Overall illness incidence rate was 19.7 episodes per 100 child-weeks, 95% CI 18.4 to 20.7. The incidence rate of fever symptoms was 5.5 episodes per 100 child-weeks; of acute respiratory infections (ARIs) 4.2 episodes per 100 child-weeks; of diarrhoea, 3.4 episodes per 100 child-weeks. In the multilevel analysis, household wealth status, child age, child nutritional status, source of drinking water, place for cooking and number of children below 5 years of age in the household were main risk factors for illnesses., Conclusions: Children below 5 years of age in Ethiopia often experience fever, ARIs and diarrhoea. The identified risk factors were related to poverty and highlighted the importance of preventive measures to reduce the incidence of these diseases., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objective: The International Code of Marketing of Breast-Milk Substitutes is an important instrument to protect and promote appropriate infant and young child feeding and the safe use of commercial milk formulas. Ghana and Tanzania implemented the Code into national legislation in 2000 and 1994, respectively. We aimed to estimate the effects of the Code implementation on child mortality (CM) in both countries., Setting: The countries analysed were Ghana and Tanzania., Participants: For CM and HIV rates, data from the Institute for Health Metrics and Evaluation from up to 2019 were used. Data for income and skilled birth rates were retrieved from the World Bank, for fertility from the World Population Prospects, for vaccination from the Global Health Observatory and for employment from the International Labour Organization., Design: We used the synthetic control group method and performed placebo tests to assess statistical inference. The primary outcomes were CM by lower respiratory infections, mainly pneumonia, and diarrhoea and the secondary outcome was overall CM., Results: One-sided inference tests showed statistically significant treatment effects for child deaths by lower respiratory infections in Ghana ( P = 0·0476) and Tanzania ( P = 0·0476) and for diarrhoea in Tanzania ( P = 0·0476). More restrictive two-sided inference tests showed a statistically significant treatment effect for child deaths by lower respiratory infections in Ghana ( P = 0·0476). No statistically significant results were found for overall CM., Conclusion: The results suggest that the implementation of the Code in both countries had a potentially beneficial effect on CM due to infectious diseases; however, further research is needed to corroborate these findings.

The aim of this study is to assess nutritional status and associated factors among infants and young children aged 6-23 months in Yeka sub-city, Ethiopia, 2021. An institution-based cross-sectional study was conducted in selected health centres found in the Yeka sub-city from May 2021 to July 2021. In total, 396 systematically selected infants and young children aged 6-23 months attended the selected health centres were included in the study. Data were collected by using a structured questionnaire and anthropometric measurements. A multinomial logistic regression model was used. The overall magnitude of undernutrition and overnutrition among infants and young children were 24.7% and 5.5%, respectively. Dietary diversity score (DDS) ((adjusted odd ratio (AOR) = 5.65; 95% CI = 2.301, 10.87; P value = 0.003), minimum meal frequency (MMF) (AOR = 5.435; 95% CI = 2.097, 11.09; P value = 0.0052), and diarrhoea (AOR = 2.52; 95% CI = 1.007, 6.310; P value = 0.002) were statistically significantly associated factors for nutritional status among infants and young children. Malnutrition (undernutrition and overnutrition) is a public health problem among infants and young children in Yeka sub-city, Ethiopia. DDS, MMF, and diarrhoeal disease were associated with higher odds of undernutrition., Competing Interests: The authors declare that they have no conflict of interests., (© The Author(s) 2024.)

Background: Diarrheal disease remains a significant public health issue, particularly affecting young children and older adults. Despite efforts to control and prevent these diseases, their incidence continues to be a global concern. Understanding the trends in diarrhea incidence and the factors influencing these trends is crucial for developing effective public health strategies., Objective: This study aimed to explore the temporal trends in diarrhea incidence and associated factors from 1990 to 2019 and to project the incidence for the period 2020-2040 at global, regional, and national levels. We aimed to identify key factors influencing these trends to inform future prevention and control strategies., Methods: The eXtreme Gradient Boosting (XGBoost) model was used to predict the incidence from 2020 to 2040 based on demographic, meteorological, water sanitation, and sanitation and hygiene indicators. SHapley Additive exPlanations (SHAP) value was performed to explain the impact of variables in the model on the incidence. Estimated annual percentage change (EAPC) was calculated to assess the temporal trends of age-standardized incidence rates (ASIRs) from 1990 to 2019 and from 2020 to 2040., Results: Globally, both incident cases and ASIRs of diarrhea increased between 2010 and 2019. The incident cases are expected to rise from 2020 to 2040, while the ASIRs and incidence rates are predicted to slightly decrease. During the observed (1990-2019) and predicted (2020-2040) periods, adults aged 60 years and above exhibited an upward trend in incidence rate as age increased, while children aged < 5 years consistently had the highest incident cases. The SHAP framework was applied to explain the model predictions. We identified several risk factors associated with an increased incidence of diarrhea, including age over 60 years, yearly precipitation exceeding 3000 mm, temperature above 20 °C for both maximum and minimum values, and vapor pressure deficit over 1500 Pa. A decreased incidence rate was associated with relative humidity over 60%, wind speed over 4 m/s, and populations with above 80% using safely managed drinking water services and over 40% using safely managed sanitation services., Conclusions: Diarrheal diseases are still serious public health concerns, with predicted increases in the incident cases despite decreasing ASIRs globally. Children aged < 5 years remain highly susceptible to diarrheal diseases, yet the incidence rate in the older adults aged 60 plus years still warrants additional attention. Additionally, more targeted efforts to improve access to safe drinking water and sanitation services are crucial for reducing the incidence of diarrheal diseases globally.

Immune checkpoint inhibitors (ICIs) have emerged as an integral component of the management of various cancers and have contributed to significant improvements in overall survival. Most available ICIs target anti-cytotoxic T-lymphocyte-associated protein 4 (anti-CTLA4), and anti-programmed cell death 1/programmed cell death ligand 1 (anti-PD1/PDL1). Gastrointestinal immune-related adverse events remain a common complication of ICIs. The predominant manifestations include diarrhea and colitis, which often manifest concurrently as immune-mediated diarrhea and colitis (IMDC). Risk factors for developing these side effects include baseline gut microbiota, preexisting autoimmune disorders, such as inflammatory bowel disease, and type of neoplasm. The hallmark symptom of colitis is diarrhea which may be accompanied by mucus or blood in stools. Patients may also experience abdominal pain, fever, vomiting, and nausea. If not treated rapidly, ICI-induced colitis can lead to serious life-threatening complications. Current management is based on corticosteroids as first-line, and immunosuppressants like infliximab or vedolizumab for refractory cases. Microbiota transplantation and specific cytokines and lymphocyte replication inhibitors are being investigated. Optimal patient care requires maintaining a balance between treatment toxicity and efficacy, hence the aim of this review is to enhance readers' comprehension of the gastrointestinal adverse events associated with ICIs, particularly IMDC. In addition to identifying the risk factors, we discuss the incidence, clinical presentation, workup, and management options of IMDC., (© 2024.

Diarrhea is the second major source of ill health and pediatric death globally. It accounts for over 90% of loss of life in infants especially those below 5 years old in developing nations. Lack of quality water and good sanitation is the principal root of diarrhea. Poor nutritional status also increases the incidence of diarrhea. The United Nations Sustainable Development Goal (SDG) number 3 targets to put a stop to avoidable deaths among newborns and infants under 5 years old by the year 2030. Interestingly, SDG number 6 targets to ensure all-round and fair access to safe quality portable water, good sanitation, and proper hygiene for everyone by the year 2030. Unfortunately, South Asia and sub-Saharan African regions are centers of limited improved water and good sanitation facilities, thus explaining the increased morbidity and loss of life orchestrated by diarrhea in young children in these areas. Therefore, enhancing water quality, good sanitation, and proper hygiene is a pivotal interposition strategy to improve children's health and well-being and achieve SDG 3, especially in the fight against diarrhea. Due to the interrelated relationship between the SDGs, improving water quality, sanitation, and hygiene (SDG 6) appears to be the foundation for achieving other goals such as reducing malnutrition (SDG 2), eradicating poverty in children (SDG 1), building good working conditions (SDG 8), protecting the environment and climatic variations (SDG 13)., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Purpose: The impact of cancer-related diarrhea (CRD) on changes in cancer therapy remains poorly characterized despite its prevalence., Methods: We performed a longitudinal observational study using IQVIA PharMetrics Plus claims data. Patients included adults with CRD identified by diagnosis codes or pharmacy claims and compared their outcomes to matched (1:1) patients without CRD. Treatment parameters (discontinuation, persistence, augmentation, dose titration, adherence) were evaluated and stratified for the first cancer therapy (chemotherapy vs. targeted therapy vs. both). A multivariate Cox proportional hazards model was used to estimate the difference in risk of each treatment parameter between cohorts, adjusting for cancer type, therapy, and comorbidities., Results: We identified 104,135 matched pairs of patients with solid (n = 94,411) or hematologic cancers (n = 9,724) receiving chemotherapy (n = 47,220), targeted therapy (n = 2,427), or both (n = 5,313). Patients with CRD discontinued therapy more frequently than those without CRD (chemotherapy [81.5% vs. 62.3%], targeted therapy [69.2% vs. 64.3%], both [96.0% vs. 85.5%], p < 0.0001). The overall proportion of discontinuation was higher (82.4% vs. 64.6%, p < 0.0001), including a higher risk of discontinuation (HR = 1.40, p < 0.001) for patients with CRD. The mean time to discontinuation (59.6 ± 54.1 vs. 68.3 ± 76.6 days), switch (72.0 ± 48.6 vs. 96.9 ± 84.0 days), persistence (95.1 ± 98.1 vs. 154.3 ± 142.7 days), and adherence (25.5% ± 37.2 vs. 47.9 ± 41%) were all lower (p < 0.0001) among patients with CRD., Conclusion: Patients who develop CRD undergo significant and clinically impactful index treatment discontinuation, treatment switching, and have lower adherence and persistence of anticancer therapy compared to patients without CRD. Strategies to control CRD to optimize cancer therapy are urgently needed., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Rotavirus is a leading cause of diarrhea in infants and young children in many low- and middle-income countries. India launched a childhood immunization program for rotavirus in 2016, starting with four states and expanding it to cover all states by 2019. The objective of this study was to estimate the effects of the rotavirus vaccination program in India on disease burden and antibiotic misuse., Methods: We built a dynamic agent-based model of rotavirus progression in children under five within each district in India. Simulations were run for various scenarios of vaccination coverage in the context of India's Universal Immunization Programme. Population data were obtained from the National Family Household Surveys and used to calibrate the models. Disease parameters were obtained from published studies. We estimated past and projected future reduction of disease burden and antibiotic misuse due to full vaccination nationwide, by state, and by wealth quintile., Results: We estimate that rotavirus vaccination in India has reduced the prevalence of rotavirus cases by 33.7% (prediction interval: 30.7-36.0%), total antibiotic misuse due to rotavirus by 21.8% (18.6-25.1%), and total deaths due to rotavirus by 38.3% (31.3-44.4%) for children under five. We estimate total antibiotic misuse due to rotavirus infection to be 7.6% (7.5-7.9%) of total antibiotic consumption in this demographic versus 9.6% (9.4-9.9%) in the absence of vaccination. We project rotaviral prevalence to drop to below one case for every 100,000 individuals in those below five if vaccination coverage is increased by 50.3% (45.2-58.5%) to 68.1% (63.1-76.4) nationwide., Conclusion: Universal coverage of childhood rotavirus vaccination can substantially reduce inappropriate antibiotic use in India., Competing Interests: Declaration of competing interest All authors declare no financial or non-financial competing interests., (Copyright © 2024 The Authors.

In this paper, we have provided more insights on the relationship between under five morbidity in Nigeria and some background characteristics using a Poisson regression model and the most recent 2018 NDHS data on Acute Respiratory Infection (ARI), diarrhoea and fever. Some of our results are that children 36-47 months old have the highest risk of ARI [OR = 1.45; CI (1.31,1.60)] while children less than 6 months old have the lowest risk of ARI [OR = 0.14; CI (0.11,0.17)]. The prevalence of diarrhoea is generally high among children under 48-59 months old but highest among children 6-11 months old [OR = 4.34; CI (3.69,5.09)]. Compared to children 48-59 months old, children in all other age categories except 24-34 months old have a high risk of fever [OR = 0.95; CI (0.73,1.24)]. ARI is more prevalent among female children [OR = 8.88; CI (8.02,9.82)] while diarrhoea [OR = 21.75; (19.10,24.76)] and fever [OR = 4.78; CI (4.31,5.32)] are more prevalent among male children. Children in urban areas are more likely to suffer ARI [OR = 9.49; CI (8.31,10.85)] while children in rural areas are more likely to suffer both diarrhoea [OR = 21.75; CI (19.10,24.76)] and fever [OR = 4.90; CI (4.26,5.63)]. Children in the South-South have the highest risk of ARI [OR = 4.03; CI (3.65,4.454)] while children in the North Central have the lowest risk of ARI [OR = 1.55; CI (1.38,1.74)] and highest risk of diarrhoea [OR = 3.34; CI (2.30,5.11)]. Children in the Northeast have the highest risk of fever [OR = 1.30; CI (1.14,1.48)]. In the Northcentral region, Kogi state has the highest prevalence of fever [OR = 2.27; CI (1.62,3.17)], while Benue state has the lowest [OR = 0.35; CI (0.20,0.60)]. Children in Abuja state face similar risks of fever and diarrhoea [OR = 0.84; CI (0.55,1.27)], with the risk of diarrhoea in Abuja being comparable to that in Plateau state [OR = 1.57; CI (0.92,2.70)]. Nasarawa state records the highest incidence of diarrhoea in the Northcentral [OR = 5.12; CI (3.03,8.65)], whereas Kogi state reports the lowest [OR = 0.29; CI (0.16,0.53)]. In the Northeast, Borno state has the highest rate of fever [OR = 3.28; CI (2.80,3.84)], and Bauchi state the lowest [OR = 0.38; CI (0.29,0.50)]. In Adamawa state, the risks of fever and diarrhoea are nearly equivalent [OR = 1.17; CI (0.97,1.41)], and the risk of fever there is similar to that in Taraba state [OR = 0.92; CI (0.75,1.12)]. Diarrhoea is most prevalent in Yobe state [OR = 3.17; CI (2.37,4.23)] and least prevalent in Borno state [OR = 0.26; CI (0.20,0.33)]. In the Northwest, the risk of fever is similarly high in Zamfara and Kebbi states [OR = 1.04; CI (0.93,1.17)], with Kastina state showing the lowest risk [OR = 0.39; CI (0.34,0.46)]. Children in Zamfara state experience notably different risks of fever and diarrhoea [OR = 0.07; CI (0.05,0.10)]. Kaduna state reports the highest incidence of diarrhoea [OR = 21.88; CI (15.54,30.82)], while Kano state has the lowest [OR = 2.50; CI (1.73,3.63)]. In the Southeast, Imo state leads in fever incidence [OR = 8.20; CI (5.61,11.98)], while Anambra state has the lowest [OR = 0.40; CI (0.21,0.78)]. In Abia state, the risk of fever is comparable to that in Enugu state [OR = 1.03; CI (0.63,1.71)], but the risks of fever and diarrhoea in Abia differ significantly [OR = 2.67; CI (1.75,4.06)]. Abia state also has the highest diarrhoea rate in the Southeast [OR = 2.67; CI (1.75,4.06)], with Ebonyi state having the lowest [OR = 0.05; CI (0.03,0.09)]. In the South-South region, Bayelsa and Edo states have similar risks of fever [OR = 1.28; CI (0.84,1.95)], with Akwa Ibom state reporting the highest fever rate [OR = 4.62; CI (3.27,6.52)] and Delta state the lowest [OR = 0.08; CI (0.02,0.25)]. Children in Bayelsa state face distinctly different risks of fever and diarrhoea [OR = 0.56; CI (0.34,0.95)]. Rivers state shows the highest incidence of diarrhoea in the South-South [OR = 10.50; CI (4.78,23.06)], while Akwa Ibom state has the lowest [OR = 0.30; CI (0.15,0.57)]. In the Southwest, Lagos and Osun states have similar risks of fever [OR = 1.00; CI (0.59,1.69)], with Ogun state experiencing the highest incidence [OR = 3.47; CI (2.28,5.28)] and Oyo state the lowest [OR = 0.18; CI (0.07,0.46)]. In Lagos state, the risks of fever and diarrhoea are comparable [OR = 0.96; CI (0.57,1.64)], and the risk of diarrhoea is similar to those in Ekiti, Ogun, and Ondo states. Oyo state has the highest diarrhoea rate in the Southwest [OR = 10.99; CI (3.81,31.67)], with Ogun state reporting the lowest [OR = 0.77; CI (0.42,1.42)]. Children of mothers with more than secondary education are significantly less likely to suffer ARI [OR = 0.35; CI (0.29,0.42)], whereas children of mothers without any education run a higher risk of diarrhoea [OR = 2.12; CI (1.89,2.38)] and fever [OR = 2.61; CI (2.34,2.91)]. Our analysis also indicated that household wealth quintile is a significant determinant of morbidity. The results in this paper could help the government and non-governmental agencies to focus and target intervention programs for ARI, diarrhoea and fever on the most vulnerable and risky under five groups and populations in Nigeria., (© 2024.

Introduction: Diarrhoea is a major public health concern in developing countries, usually exacerbated by poor water, sanitation and hygiene but its aetiology is under-studied, particularly away from capital cities. We identified diarrhoeagenic Escherichia coli (DEC) from stools collected in Ile-Ife and Ilesa, Osun state, Nigeria and determined their antibiotic resistance profiles., Methods: Stool samples from 167 children with diarrhoea and 334 controls under the age of 5 years were cultured for Escherichia coli and Salmonella. Bacterial isolates were identified biochemically and DEC were identified by PCR. Antimicrobial susceptibility testing was by modified Kirby-Bauer disc diffusion method in accordance with the CLSI guidelines. Data were analyzed using Chi-square and Fisher's exact tests., Result: Diarrhoea infection is significantly high among children under 12 months (p = 0.002), caregivers without at least primary school education (p = 0.006), breastfeeding for under 6 months (p˂0.001), and caregivers who were siblings (p = 0.004). DEC was detected in 69(41.3%) cases but only 86(25.7%) controls (p < 0.001) and more commonly recovered during the wet season (p < 0.001). Enterotoxigenic E. coli (p = 0.031), enteropathogenic E. coli (p = 0.031) and Shiga-toxin-producing E. coli (p = 0.044) were recovered more commonly from cases than controls. DEC from patients with diarrhoea were commonly resistant to sulphonamides (91.3%), trimethoprim (82.6%), and ampicillin (78.3%) but were largely susceptible to quinolones and carbapenems (97.1%)., Conclusion: Enteropathogenic, enterotoxigenic and Shiga toxin-producing E. coli are associated with diarrhoea in our setting, and show considerable resistance to first-line antimicrobials. Risk factors for DEC diarrhoea include infancy, inadequate breastfeeding and caregivers with education below primary school., (© 2024. The Author(s).)

Background: In sub-Saharan African countries, preventable and manageable diseases such as diarrhea and acute respiratory infections still claim the lives of children. Hence, this study aims to estimate the rate of change in the log expected number of days a child suffers from Diarrhea (NOD) and flu/common cold (NOF) among children aged 6 to 11 months at the baseline of the study., Methodology: This study used secondary data which exhibit a longitudinal and multilevel structure. Based on the results of exploratory analysis, a multilevel zero-inflated Poisson regression model with a rate of change in the log expected NOD and NOF described by a quadratic trend was proposed to efficiently analyze both outcomes accounting for correlation between observations and individuals through random effects. Furthermore, residual plots were used to assess the goodness of fit of the model., Results: Considering subject and cluster-specific random effects, the results revealed a quadratic trend in the rate of change of the log expected NOD. Initially, low dose iron Micronutrient Powder (MNP) users exhibited a higher rate of change compared to non-users, but this trend reversed over time. Similarly, the log expected NOF decreased for children who used MNP and exclusively breastfed for six months, in comparison to their counterparts. In addition, the odds of not having flu decreased with each two-week increment for MNP users, as compared to non-MNP users. Furthermore, an increase in NOD resulted in an increase in the log expected NOF. Region and exclusive breastfeeding also have a significant relationships with both NOD and NOF., Conclusion: The findings of this study underscore the importance of commencing analysis of data generated from a study with exploratory analysis. The study highlights the critical role of promoting EBF for the first six months and supporting children with additional food after six months to reduce the burden of infectious diseases., (© 2024.

Background: Bangladesh has seen a significant decline in child mortality in recent decades, but morbidity among children <5 y of age remains high. The aim of this analysis was to examine trends and identify risk factors related to child morbidity in Bangladesh., Methods: This analysis is based on data from four successive cross-sectional Bangladesh Demographic and Health Surveys for the years 2007, 2011, 2014 and 2017-18. Several count regression models were fitted and the best model was used to identify risk factors associated with morbidity in children <5 y of age., Results: According to the results of the trend analysis, the prevalence of non-symptomatic children increased and the prevalence of fever, diarrhoea and acute respiratory infections (ARIs) decreased over the years. The Vuong's non-nested test indicated that Poisson regression could be used as the best model. From the results of the Poisson regression model, child age, sex, underweight, wasted, stunting, maternal education, wealth status, religion and region were the important determinants associated with the risk of child morbidity. The risk was considerably higher among women with a primary education compared with women with a secondary or greater education in Bangladesh., Conclusions: This analysis concluded that child morbidity is still a major public health problem for Bangladesh. Thus it is important to take the necessary measures to reduce child morbidity (particularly fever, diarrhoea and ARI) by improving significant influencing factors., (© The Author(s) 2023.

Background: Diarrhea diseases continue to present a significant threat to the well-being of children under the age of five in Africa, thereby contributing substantially to both morbidity and mortality rates. The period spanning between January 2013 and December 2023 has witnessed persistent challenges in the fight against these diseases, thereby necessitating a thorough investigation into the factors that determine their occurrence. It is important to note that the burden of diarrhea diseases is not evenly distributed across the continent, with residence, socioeconomic, and environmental factors playing pivotal roles in shaping the prevalence and incidence rates. Consequently, this systematic review aimed to consolidate and analyze the existing body of literature on the determinants of diarrhea diseases among children under the age of five in Africa between January 2013 and December 2023., Method: The systematic review employed a rigorous methodological approach to examine the determinants of diarrhea diseases among children under the age of five in Africa between January 2013 and December 2023. A comprehensive search strategy was implemented, utilizing databases such as PubMed, Scopus, and Web of Science, and incorporating relevant keywords. The inclusion criteria focused on studies published within the specified timeframe, with a specific focus on the determinants of diarrhea disease among children under the age of five in Africa. The study selection process involved a two-stage screening, with independent reviewers evaluating titles, abstracts, and full texts to determine eligibility. The quality assessment, employing a standardized tool, ensured the inclusion of studies with robust methodologies. Data extraction encompassed key study details, including demographics, residence factors, socioeconomic influences, environmental variables, and intervention outcomes., Results: The search yielded a total of 12,580 articles across 25 African countries; however, only 97 of these articles met the inclusion criteria and were ultimately included in the systematic review. The systematic review revealed geographic and seasonal disparities in the prevalence of diarrhoeal diseases across different countries in Africa. Factors such as age-related vulnerabilities, gender disparities, maternal occupation, disposal of young children's stools, and economic status were identified as significant determinants of the prevalence of diarrhea disease., Conclusion: This systematic review provides a comprehensive understanding of the determinants of diarrhea diseases among children under the age of five in Africa between January 2013 and December 2023. The nuanced analysis of residence variations, socioeconomic influences, environmental factors, and intervention outcomes underscores the complex nature of this issue. The findings highlight the necessity for region-specific and context-sensitive interventions to address the unique challenges faced by diverse communities. This review serves as a valuable resource for policymakers, healthcare professionals, and researchers, guiding the development of evidence-based strategies aimed at reducing the burden of diarrhea diseases and improving child health outcomes in Africa., (© 2024.

Diarrhea claims >500,000 lives annually among children under five years of age in low- and middle-income countries. Mortality due to acute diarrhea (<7 days' duration) is decreasing, but prolonged (7-13 days) and persistent (≥14 days of duration) diarrhea remains a massive challenge. Here, we use a case-control study to decipher if fecal gut microbiota compositional differences between Ethiopian children with acute (n=554) or prolonged/persistent (n=95) diarrhea and frequency-matched non-diarrheal controls (n=663) are linked to diarrheal etiology. We show that diarrhea cases are associated with lower bacterial diversity and enriched in Escherichia spp., Campylobacter spp., and Streptococcus spp. Further, diarrhea cases are depleted in gut commensals such as Prevotella copri, Faecalibacterium prausnitzii, and Dialister succinatiphilus, with depletion being most pronounced in prolonged/persistent cases, suggesting that prolonged duration of diarrhea is accompanied by depletion of gut commensals and that re-establishing these via e.g., microbiota-directed food supplements offer a potential treatment strategy., (© 2024.

Background: School-based water, sanitation and hygiene (WASH) may improve the health and attendance of schoolchildren, particularly post-menarcheal girls, but existing evidence is mixed. We examined the impact of an urban school-based WASH programme (Project WISE) on child health and attendance., Methods: The WISE cluster-randomised trial, conducted in 60 public primary schools in Addis Ababa, Ethiopia over one academic year, enrolled 2-4 randomly selected classes per school (~ 100 pupils) from grades 2 to 8 (aged 7-16) in an 'open cohort'. Schools were assigned 1:1 by stratified randomisation to receive the intervention during the 2021/2022 or the 2022/2023 academic year (waitlist control). The intervention included improvements to drinking water storage, filtration and access, handwashing stations and behaviour change promotion. Planned sanitation improvements were not realised. At four unannounced classroom visits post-intervention (March-June 2022), enumerators recorded primary outcomes of roll-call absence, and pupil-reported respiratory illness and diarrhoea in the past 7 days among pupils present. Analysis was by intention-to-treat., Results: Of 83 eligible schools, 60 were randomly selected and assigned. In total, 6229 eligible pupils were enrolled (median per school 101.5; IQR 94-112), 5987 enrolled at study initiation (23rd November-22nd December 2021) and the remaining 242 during follow-up. Data were available on roll-call absence for 6166 pupils (99.0%), and pupil-reported illness for 6145 pupils (98.6%). We observed a 16% relative reduction in odds of pupil-reported respiratory illness in the past 7 days during follow-up in intervention vs. control schools (aOR 0.84; 95% CI 0.71-1.00; p = 0.046). There was no evidence of effect on pupil-reported diarrhoea in the past 7 days (aOR 1.15; 95% CI 0.84-1.59; p = 0.39) nor roll-call absence (aOR 1.07; 95% 0.83-1.38; p = 0.59). There was a small increase in menstrual care self-efficacy (aMD 3.32 on 0-100 scale; 95% CI 0.05-6.59), and no evidence of effects on other secondary outcomes., Conclusions: This large-scale intervention to improve school WASH conditions city-wide had a borderline impact on pupil-reported respiratory illness but no effect on diarrhoeal disease nor pupil absence.

We performed a review of published and gray literature of human Hymenolepis diminuta cases across Europe up to July 2022. Of all detectable publications and records, we further analyzed only those that contained demographic, clinical or epidemiological data regarding the infected subjects. Additionally, one case of hymenolepiasis in a 16-mo-old boy living in the urban part of Belgrade was included in the analysis. Published studies were based in 13/50 European countries and identified 104 laboratory-confirmed cases in total. Almost one-half (49%) of all cases originated from Mediterranean countries. Among symptomatic children, the infection most often manifested with diarrhea, abdominal pain, allergic reaction and behavioral changes. The diagnosis was made by the detection and identification of H. diminuta eggs or parts of strobila in stool samples, although cases of misdiagnosis were also reported. The parasite clearance was established with praziquantel or niclosamide, while the administration of albendazole or mebendazole led to unfavorable results. Future multicentric prospective studies focused on infection screening and the gathering of detailed sociodemographic and clinical data could provide an updated insight into the true distribution and characteristics of H. diminuta infection across Europe., (© The Author(s) 2024.

Cryptosporidiosis has previously been reported in animals, humans, and water sources in the United Arab Emirates (UAE). However, most reports were only to the genus level, or generically identified as cryptosporidiosis. We aimed to investigate the genetic diversity of Cryptosporidium species occurring in diarrhetic ungulates which were brought to the Central Veterinary Research Laboratory (CVRL) in Dubai. Using a combination of microscopic and molecular methods, we identified five species of Cryptosporidium occurring among ungulates in the UAE, namely C. parvum, C. hominis, C. xiaoi, C. meleagridis, and C. equi. Cryptosporidium parvum was the most prevalent species in our samples. Furthermore, we identified subtypes of C. parvum and C. hominis, which are involved in both human and animal cryptosporidiosis. This is also the first reported occurrence of Cryptosporidium spp. in the Arabian Tahr, to our knowledge. Since the animals examined were all in contact with humans, the possibility of zoonotic spread is possible. Our study correlates with previous reports in the region, building upon the identification of Cryptosporidium sp. However, there is a need to further investigate the endemic populations of Cryptosporidium, including more hosts, sampling asymptomatic animals, and location data., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Importance: Despite advancements in herd management, feeding, and pharmaceutical interventions, neonatal calf diarrhea (NCD) remains a major global health concern. Bacteria, viruses, and parasites are the major contributors to NCD. Although several pathogens have been identified in the Republic of Korea (ROK), the etiological agents of numerous NCD cases have not been identified., Objective: To identify, for the first time, the prevalence and impact of Boosepivirus (BooV) on calf diarrhea in the ROK., Methods: Here, the unknown cause of calf diarrhea was determined using metagenomics We then explored the prevalence of certain pathogens, including BooV, that cause NCD. Seventy diarrheal fecal samples from Hanwoo ( Bos taurus coreanae ) calves were analyzed using reverse transcriptase and quantitative real-time polymerase chain reaction for pathogen detection and BooV isolate sequencing., Results: The complete genome of BooV was detected from unknown causes of calf diarrhea. And also, BooV was the most frequently detected pathogen (35.7%) among 8 pathogens in 70 diarrheic feces from Hanwoo calves. Co-infection analyses indicated that most BooV-positive samples were solely infected with BooV, indicating its significance in NCD in the ROK. All isolates were classified as BooV B in phylogenetic analysis., Conclusions and Relevance: This is the first study to determine the prevalence and molecular characteristics of BooV in calf diarrhea in the ROK, highlighting the potential importance of BooV as a causative agent of calf diarrhea and highlighting the need for further research on its epidemiology and pathogenicity., Competing Interests: The authors declare no conflicts of interest., (© 2024 The Korean Society of Veterinary Science.)

Background: Diarrheal illness is a prominent public health worry in developing countries, resulting in high mortality among children. Sociodemographic characteristics and geographic settings are the main effective factors for the increased incidence of childhood diarrhea. Aeromonas is a neglected organism capable of causing dysentery and diarrhea. The aim of this systematic review and meta-analysis was to determine the prevalence of Aeromonas as an agent in the causation of diarrhea in Asian children. Methods: We conducted a systematic review using Web of Science, PubMed, Wiley Online Library, Science Direct, and Google Scholar for peer-reviewed articles published between January 2000 and February 2023. We considered studies that found Aeromonas in diarrheal stool. A random-effects model was used to determine the pooled prevalence of Aeromonas . Results: Our search returned 2,057 articles, with 17 articles from seven Asian nations being included in the systematic review. The pooled prevalence of Aeromonas was 4.5% (95% confidence interval [CI]: 2.9%-6.8%), with heterogeneity ( I 2 = 96.85; p < 0.001). There was a greater prevalence in areas with high population living in poverty (12.2%; 95% CI: 5.8%-24%) and lower-middle-income countries (5.0%; 95% CI: 2.7%-9.0%). In addition, the prevalence of Aeromonas was greater in South Asia (10.0%; 95% CI: 5.6%-17.2%), in India (12.9%; 95% CI: 6.8%-23%), and in countries with open defecation rate of 5%-25% (11.3%; 95% CI: 6.3%-19.2%). Conclusion: The prevalence of Aeromonas -associated diarrhea in children in Asia estimated in the present study highlighted the high burden of Aeromonas in some parts of Asia.

Infectious causes of diarrhea contribute significantly to morbidity in Asia. We conducted a systematic review and meta-analysis of the prevalence of infectious etiologies of persistent and chronic diarrhea in Asian adults. Searches were performed on PubMed and Scopus for studies from January 1, 1970, to May 30, 2023. Sixteen studies were identified and included. The meta-analysis was conducted with the random-effects method, estimating the pooled prevalence of groups of infectious pathogens as causes of persistent and chronic diarrhea among Asian adults. The findings were highly heterogeneous and indicative of publication bias. The majority of studies were conducted on persons living with human immunodeficiency virus infection (PLHIV). The studies were predominantly from low-income and middle-income Asian countries. The most common cause was parasitic, with a pooled prevalence of 0.52 (95% confidence interval 0.28-0.65, I 2  = 99%, Cochran's Q = 1027.44, P < 0.01), followed by bacterial, fungal, and viral causes, which were substantially rarer. Negative microbiological testing was also common, with a pooled prevalence for a negative test being 0.37 (95% confidence interval 0.17-0.52, I 2  = 99%, Cochran's Q = 1027.44, P < 0.01). Subgroup analyses of studies conducted among PLHIV, from year 2000 and among those conducted in Southeast Asia showed a similar prevalence of parasitic causes of diarrhea. In conclusion, in Asian adults with persistent and chronic diarrhea, parasitic causes were most prevalent. However, the estimate of true prevalence is limited by significant heterogeneity among the available studies. More study in this field is required, especially examining PLHIV in the post-antiretroviral therapy era and from high-income countries., (© 2024 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

Background: Despite common global usage, fluoropyrimidine (FP; 5-flurouracil and capecitabine)-related chemotherapy toxicity is poorly reported in the literature, with serious toxicity ranging from 10% to 40% and early toxicity (within 60 days of exposure) quoted at 14%. Data reflecting the incidence of Grades 3-5 FP-related toxicity in Australian cancer patients is scant, despite the significant impact of toxicity on patients (hospitalisations, intensive care unit (ICU) admissions and even death)., Aims: This retrospective audit evaluated Grades 3-5 toxicities in a contemporaneous cohort of 500 patients receiving FP chemotherapies within the Hunter-New England Local Health District from June 2020 to June 2022. Data were extracted from public hospital records and oncology-specific e-records to determine rates of toxicity and associated hospitalisations, intensive care admissions and deaths that occurred within 60 days of first exposure to FP chemotherapy-containing regimens., Results: One hundred and fifty incidents of Grades 3-4 toxicity in the first 60 days led to 87 patients presenting to hospital (87/500, 17.4%). The most common serious toxicities were diarrhoea (39.3%), nausea and vomiting (22.7%) and febrile neutropaenia (10%). Four patients were admitted to the ICU, and four patients died of toxicity. Within the first 60 days, 22.2% of patients required treatment delays, 21.4% required dose reductions, and 7.8% of patients ceased treatment because of toxicities., Discussion and Conclusion: Our experience reflects international reports and is likely generalisable to the Australian population. These data are a basis to understand the potential benefits of precision medicine strategies such as pharmacogenomic screening to improve patient tolerability and the cost-effectiveness of FP chemotherapy prescribing., (© 2024 Royal Australasian College of Physicians.)

Intestinal pathogenic Escherichia coli (InPEC) is one of the most common causes of bacterial diarrhea in farm animals, including profuse neonatal diarrhea and post weaning diarrhea (PWD) in piglets. In this study, we investigated the prevalence of InPEC and associated primary virulence factors among 543 non-duplicate E. coli isolates from diarrheal pigs from 15 swine farms in southern China. Six major virulence genes associated with InPEC were identified among 69 (12.71 %) E. coli isolates and included est (6.62 %), K88 (4.79 %), elt (3.68 %), eae (1.47 %), stx2 (0.92 %) and F18 (0.55 %). Three pathotypes of InPEC were identified including ETEC (8.10 %), EPEC (1.29 %) and STEC/ETEC (0.92 %). In particular, K88 was only found in ETEC from breeding farms, whereas F18 was only present in STEC/ETEC hybrid from finishing farms. Whole genome sequence analysis of 37 E. coli isolates revealed that InPEC strains frequently co-carried multiple antibiotic resistance gene (ARG). est, elt and F18 were also found to co-locate with ARGs on a single IncFIB/IncFII plasmid. InPEC isolates from different pathotypes also possessed different profiles of virulence genes and antimicrobial resistance genes. Population structure analysis demonstrated that InPEC isolates from different pathotypes were highly heterogeneous whereas those of the same pathotype were extremely similar. Plasmid analysis revealed that K88 and/or est/elt were found on pGX18-2-like/pGX203-2-like and pGX203-1-like IncFII plasmids, while F18 and elt/est, as well as diverse ARGs were found to co-locate on IncFII/IncFIB plasmids with a non-typical backbone. Moreover, these key virulence genes were flanked by or adjacent to IS elements. Our findings indicated that both clonal expansion and horizontal spread of epidemic IncFII plasmids contributed to the prevalence of InPEC and the specific virulence genes (F4, F18, elt and est) in the tested swine farms., Competing Interests: Declaration of Competing Interest We declare that we have no conflict of interest., (Copyright © 2024 Elsevier B.V.

Background: Clostridioides difficile infection (CDI) is an increasingly common disease in healthcare facilities and community settings. However, there are limited reports of community-onset CDI (CO-CDI) in China., Methods: We collected diarrheal stool samples from 3885 patients who went to outpatient department or emergency department in a tertiary hospital in China during 2010-2023, analyzed the correlation between patients' basic information and the detection rate of CDI. Besides, all stool samples from 3885 outpatients included were tested by culturing. Moreover, we randomly selected 89 patients' stools during the 14 years and isolated 126 C. difficile strains from them. The presence of toxin genes (tcdA, tcdB, cdtA, and cdtB) were confirmed by PCR. Toxigenic strains were typed using multilocus sequence typing (MLST). Susceptibility to 9 antimicrobials was evaluated using the E-test., Results: 528 of 3885 patients (13.6 %) with diarrhea were finally diagnosed as CDI. The median age of patients included was 51 years (6 months-95 years), while the median of patients with CDI was older than patients with negative results [55.5 years (6 months-93 years) vs. 50 years (9 months -95 years), p < 0.001]. In winter, patients with diarrhea might be more likely to have CDI. The detection rate of CDI of patients in emergency department was much higher than those in other outpatients (20.7 % vs. 12.4 %, p < 0.001), and did differ from each outpatient departments (p < 0.05). There were 95 isolated strains detected as toxigenic C. difficile. Among these strains, 82 (86.3 %) had the tcdA and tcdB genes (A+B+) and 5 of these 82 strains were positive for the binary toxin genes (cdtA and cdtB) (A+B+CDT+). There were 15 different sequence types (STs) by multilocus sequence typing (MLST), while the most ST was ST-54 (23.2 %). ST types composition was relatively stable over the time span of this study. Some strains had high resistance to ciprofloxacin, clindamycin, and erythromycin. Twenty-three isolates (24.2 %) were multidrug-resistant., Conclusions: Outpatients with CDI were common among patients having diarrhea during this period in our hospital. Elderly patients and patients went to emergency department may be susceptible to CDI. Based on MLST, the result revealed that the C. difficile isolates had high genetic diversity and maintained stability in this period. All isolates were susceptible to metronidazole and vancomycin, and nearly one quarter of all isolates had multidrug resistance., Competing Interests: Conflict of Interest The authors declare that they have no competing interests., (Copyright © 2024 The Authors.

Background: The second most common cause of death for children under five is diarrhea. Early Predicting diarrhea disease and identify its determinants (factors) using an advanced machine learning model is the most effective way to save the lives of children. Hence, this study aimed to predict diarrheal diseases, identify their determinants, and generate some rules using machine learning models., Methods: The study used secondary data from the 12 east African countries for DHS dataset analysis using Python. Machine learning techniques such as Random Forest, Decision Tree (DT), K-Nearest Neighbor, Logistic Regression (LR), wrapper feature selection and SHAP values are used for identify determinants., Result: The final experimentation results indicated the random forest model performed the best to predict diarrhea disease with an accuracy of 86.5%, precision of 89%, F-measure of 86%, AUC curve of 92%, and recall of 82%. Important predictors' identified age, countries, wealth status, mother's educational status, mother's age, source of drinking water, number of under-five children immunization status, media exposure, timing of breast feeding, mother's working status, types of toilet, and twin status were associated with a higher predicted probability of diarrhea disease., Conclusion: According to this study, child caregivers are fully aware of sanitation and feeding their children, and moms are educated, which can reduce child mortality by diarrhea in children in east Africa. This leads to a recommendation for policy direction to reduce infant mortality in East Africa., (© 2024. The Author(s).)

Background: Vancomycin-resistant enterococci (VRE) have become an increasing public health concern in the past few decades, being associated with serious multidrug-resistant (MDR) infections. This study was conducted to investigate the role of diarrheic pet animals as potential reservoirs for virulent extensively drug-resistant (XDR) VRE and their threat on human health. Materials and Methods: Rectal swabs were collected from 153 diarrheic pet animals (80 dogs and 73 cats). The collected swabs were cultured on CHROMagar TM VRE for the isolation of vancomycin-resistant Enterococcus faecalis and Enterococcus faecium , and then suspected colonies were identified as enterococci after Gram staining, conventional biochemical tests, and molecular techniques. VRE were basically identified using the disk diffusion method; however, molecular identification of vanA and vanB genes was carried out among confirmed VRE isolates. Moreover, three virulence genes (cytolysin A, cylA ; enterococcal surface protein, esp ; and hyaluronidase, hyl ) were investigated in VRE isolates. Thereafter, VRE strains that harbored virulence genes were tested for antimicrobial susceptibility. Results: Eighteen out of 153 animals (11.8%) were positive for VRE, which were obtained from 15% and 8.2% of the examined dogs and cats, respectively. None of the obtained isolates carried the vanA gene, whereas the vanB gene was detected in E. faecalis (4/10) with a prevalence rate (40%). Of the obtained VRE isolates, five possessed esp and/or cylA , while all strains were negative for the hyl gene. Furthermore, four virulent VRE isolates exhibited an XDR pattern, and one isolate was MDR. Conclusion: Diarrheic pet animals could represent a potential zoonotic reservoir for virulent XDR vancomycin-resistant E. faecalis , which may have serious public health implications.

Background: The WASH benefits Bangladesh trial multi-component sanitation intervention reduced diarrheal disease among children < 5 years. Intervention components included latrine upgrades, child feces management tools, and behavioral promotion. It remains unclear which components most impacted diarrhea., Methods: We conducted mediation analysis within a subset of households (n = 720) from the sanitation and control arms. Potential mediators were categorized into indicators of latrine quality, latrine use practices, and feces management practices. We estimated average causal mediation effects (ACME) as prevalence differences (PD), defined as the intervention's effect on diarrhea through its effect on the mediator., Results: The intervention improved all indicators compared to controls. We found significant mediation through multiple latrine use and feces management practice indicators. The strongest mediators during monsoon seasons were reduced open defecation among children aged < 3 and 3-8 years, and increased disposal of child feces into latrines. The strongest mediators during dry seasons were access to a flush/pour-flush latrine, reduced open defecation among children aged 3-8 years, and increased disposal of child feces into latrines. Individual mediation effects were small (PD = 0.5-2 percentage points) compared to the overall intervention effect but collectively describe significant mediation pathways., Discussion: The effect of the WASH Benefits Bangladesh sanitation intervention on diarrheal disease was mediated through improved child feces management and reduced child open defecation. Although the intervention significantly improved latrine quality, relatively high latrine quality at baseline may have limited benefits from additional improvements. Targeting safe child feces management may increase the health benefits of rural sanitation interventions., (© 2024. The Author(s).)

Aims: This study aimed to investigate the association between diarrhea or constipation and urinary incontinence (UI) in adults., Methods: Data from the National Health and Nutrition Examination Survey for 2009-2010 was used to include 4686 adults aged 20 and over in the analysis. Stress urinary incontinence (SUI) and urgency urinary incontinence (UUI) were used as outcome variables, with diarrhea and constipation as exposure factors. We first compared the baseline characteristics of those with and without SUI, as well as those with and without UUI. The impact of diarrhea or constipation on SUI and UUI was assessed using multivariate logistic regression models. To ensure the stability of the results, subgroup and stratified analyses were conducted., Results: The prevalence rates of UUI and SUI were 22.49% and 23.39%, respectively. Adjusted multivariate logistic regression analysis revealed that the risk of UUI was increased by either diarrhea (OR 1.66, 95% CI 1.36-2.04) or constipation (OR 1.42, 95% CI 1.11-1.83). The risk of SUI was also elevated by either diarrhea (OR 1.36, 95% CI 1.11-1.67) or constipation (OR 1.32, 95% CI 1.06-1.63). Subgroup analysis revealed no significant differences in the interaction tests between constipation or diarrhea and UI., Conclusions: This study found that both constipation and diarrhea increase the risk of UUI and SUI., (© 2024 Wiley Periodicals LLC.)

Interest in dairy cow health continues to grow as we better understand health's relationship with production potential and animal welfare. Over the past decade, efforts have been made to incorporate health traits into national genetic evaluations. However, they have focused on the mature cow, with calf health largely being neglected. Diarrhoea and respiratory disease comprise the main illnesses with regard to calf health. Conventional methods to control calf disease involve early separation of calves from the dam and housing calves individually. However, public concern regarding these methods, and growing evidence that these methods may negatively impact calf development, mean the dairy industry may move away from these practices. Genetic selection may be a promising tool to address these major disease issues. In this review, we examined current literature for enhancing calf health through genetics and discussed alternative approaches to improve calf health via the use of epidemiological modelling approaches, and the potential of indirectly selecting for improved calf health through improving colostrum quality. Heritability estimates on the observed scale for diarrhoea ranged from 0.03 to 0.20, while for respiratory disease, estimates ranged from 0.02 to 0.24. The breadth in these ranges is due, at least in part, to differences in disease prevalence, population structure, data editing and models, as well as data collection practices, which should be all considered when comparing literature values. Incorporation of epidemiological theory into quantitative genetics provides an opportunity to better determine the level of genetic variation in disease traits, as it accounts for disease transmission among contemporaries. Colostrum intake is a major determinant of whether a calf develops either respiratory disease or diarrhoea. Colostrum traits have the advantage of being measured and reported on a continuous scale, which removes the issues classically associated with binary disease traits. Overall, genetic selection for improved calf health is feasible. However, to ensure the maximum response, first steps by any industry members should focus efforts on standardising recording practices and encouragement of uploading information to genetic evaluation centres through herd management software, as high-quality phenotypes are the backbone of any successful breeding programme., (Copyright © 2024 The Authors.

Diarrheal disease remains a significant cause of preventable morbidity and mortality in the pediatric population, particularly among children below five years of age. Although the occurrence of diarrheal episodes is on the decline, its impact continues to escalate at a concerning rate among children under the age of five, especially in developing countries. The objective of this paper is to investigate the factors associated with diarrhea in Yemeni children younger than five years, drawing on data from the latest edition of the Multiple Indicator Cluster Survey (MICS) Yemen conducted in 2022-2023. To identify factors associated with the prevalence of childhood diarrhea, bivariate analysis and multivariable logistic regression were utilized. The findings of this study suggest that age group 6-23, unimproved sanitation, and low-income households are associated with high risk of diarrhea in children under five years of age in Yemen. The study contributes additional evidence regarding factors that should be prioritized in public health strategies geared towards reducing diarrheal prevalence among Yemeni children., (© 2024.

Objectives: This study aimed to identify and characterise the determinants influencing the occurrence of diarrheal diseases in children aged 6-24 months undergoing complementary feeding within a low-income urban community in Kenya., Methods: This study followed a cross-sectional design and recruited caregivers of children aged 6-24 months from 302 households. The dependent variable was the 2-week diarrhoea prevalence among children, with independent variables including sociodemographic characteristics, child immunisation and feeding status, and water and sanitation facilities. Data analysis was performed using SPSS. Descriptive statistics and logistic regression analyses were used to assess associations between independent variables and the occurrence of diarrheal diseases., Results: The majority of caregivers were female (n = 282, 93.4%), aged 25-34 years (n = 156, 51.7%), had attained secondary school education (n = 154, 51%), were unemployed (n = 162, 53.6%), and earned Ksh 10,000 (USD 100) or less. 296 (98%) indexed children were fully vaccinated against rotavirus. Most households used improved drinking water sources (n = 272, 90.1%). Most caregivers did not regularly wash their hands with soap and water (n = 225, 74.5%). The 2-week diarrhoea prevalence among children was 34.1% (103/302), with 69.9% (72/103) of these cases seeking care at a healthcare facility. Logistic regression analysis revealed that children of caregivers earning Ksh 20,000 and below (aOR = 2.9[1.3-6.5], p = 0.01), and those from households using unimproved sanitation facilities (aOR = 1.9 [CI 1-3.4], p = 0.042), had significantly higher odds of having diarrhoea., Conclusion: The study found a high prevalence of diarrhoea in Kenyan children aged 6-24 months, with caregiver income and household sanitation facilities significantly impacting the occurrence of the disease. The study suggests integrated approaches, including education, income generation, hygiene, and improved nutrition, to address the burden of diarrheal disease., (© 2024 John Wiley & Sons Ltd.)

Group A rotaviruses (RVAs) are major causes of severe gastroenteritis in infants and young animals. To enhance our understanding of the relationship between human and animals RVAs, complete genome data are necessary. We screened 92 intestinal and stool samples from diarrheic piglets by RT‒PCR targeting the VP6 gene, revealing a prevalence of 10.9%. RVA was confirmed in two out of 5 calf samples. We successfully isolated two porcine samples using MA104 cell line. The full-length genetic constellation of the two isolates were determined to be G9-P[23]-I5-R1-C1-M1-A8-N1-T7-E1-H1, with close similarity to human Wa-like and porcine strains. Sequence analysis revealed the majority of genes were closely related to porcine and human RVAs. Phylogenetic analysis revealed that these isolates might have their ancestral origin from pigs, although some of their gene segments were related to human strains. This study reveals evidence of reassortment and possible interspecies transmission between pigs and humans in China., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: There is no documented experience in the use of the WHO standards for improving the quality of care (QOC) for children at the facility level. We describe the use of 10 prioritised WHO-Standard-based Quality Measures to assess QOC for children with acute diarrhoea (AD) in Italy., Methods: In a multicentre observational study in 11 paediatric emergency departments with different characteristics and geographical location, we collected data on 3061 children aged 6 months to 15 years with AD and no complications. Univariate and multivariate analyses were conducted., Results: Study findings highlighted both good practices and gaps in QoC, with major differences in QOC across facilities. Documentation of body weight and temperature varied from 7.7% to 98.5% and from 50% to 97.7%, respectively (p<0.001); antibiotic and probiotic prescription rates ranged from 0% to 10.1% and from 0% to 80.8%, respectively (p<0.001); hospitalisations rates ranged between 8.5% and 62.8% (p<0.001); written indications for reassessment were provided in 10.4%-90.2% of cases (p<0.001). When corrected for children's individual characteristics, the variable more consistently associated with each analysed outcome was the individual facility. Higher rates of antibiotics prescription (+7.6%, p=0.04) and hospitalisation (+52.9%, p<0.001) were observed for facilities in Southern Italy, compared with university centres (-36%, p<0.001), independently from children characteristics. Children's clinical characteristics in each centre were not associated with either hospitalisation or antibiotic prescription rates., Conclusions: The 10 prioritised WHO-Standard-based Quality Measures allow a rapid assessment of QOC in children with AD. Action is needed to identify and implement sustainable and effective interventions to ensure high QOC for all children., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.
