Malnutrition coupled with diarrheal and respiratory infections among children in Asia: A systematic review

Growth Monitoring and Promotion Service Utilisation and Associated Factors among Children in Afar Region, Northeast Ethiopia

The use of growth monitoring and promotion (GMP) services in the first two years of life can facilitate the early identification of common childhood health issues such as malnutrition and infections. It also creates an opportunity to promote education and nutritional counselling. This study is the first to investigate the use of GMP and its influencing factors among mothers in Ethiopia's pastoralist regions, including the Afar National and Regional State, where childhood malnutrition is a significant cause of morbidity and mortality. Between May and June 2021, a cross-sectional study was conducted within the Semera-Logia city administration. The study used a random sampling technique to select 396 children under two, and data were gathered using an interviewer-administered questionnaire. Multivariable logistic regression was used to analyse the influence of explanatory variables, which included socio-demographic, health service, and health literacy factors, on the utilisation of GMP services. The overall utilisation of GMP services was 15.9% (95% confidence intervals [CI]: 12.0%, 19.5%). Children whose fathers had college or higher education were more likely to utilise GMP services (adjusted odd ratios [AOR] = 7.75; 95% CI: 3.01, 19.99), whereas children living in households with more children were less likely to utilise GMP services (AOR = 0.11; 95% CI: 0.04, 0.28 for households with 3-4 children and AOR = 0.23; 95% CI: 0.08, 0.67 for households with 4+ children). Children who received postnatal care had higher odds of GMP service use (AOR = 8.09; 95% CI: 3.19, 20.50). GMP services are not being fully utilised to decrease infant and child morbidity and mortality caused by malnutrition in Ethiopia. We recommend strengthening GMP services in Ethiopia and taking targeted action to address the low attainment of parental education and poor postnatal care utilisation. Public health initiatives such as the implementation of mobile health (mHealth) approaches and education of mothers by female community healthcare workers on the significance of GMP services could be effective in increasing GMP service utilisation.

A Double-Blind, Randomized Intervention Study on the Effect of a Whey Protein Concentrate on E. coli-Induced Diarrhea in a Human Infection Model

Infectious diseases are a major cause of morbidity and mortality worldwide. Nutritional interventions may enhance resistance to infectious diseases or help to reduce clinical symptoms. Here, we investigated whether a whey protein concentrate (WPC) could decrease diarrheagenic Escherichia coli-induced changes in reported stool frequency and gastrointestinal complaints in a double-blind, parallel 4-week intervention study. Subjects were randomly assigned to a whey hydrolysate placebo group, a low-dose WPC group or a high-dose WPC group. After 2 weeks of consumption, subjects (n = 121) were orally infected with a high dose of live but attenuated diarrheagenic E. coli (strain E1392/75-2A; 1E10 colony-forming units). Subjects recorded information on stool consistency and the frequency and severity of symptoms in an online diary. The primary outcome parameters were a change in stool frequency (stools per day) and a change in Gastrointestinal Symptom Rating Scale (GSRS) diarrhea score between the first and second days after infection. Neither dose of the whey protein concentrate in the dietary treatment affected the E. coli-induced increase in stool frequency or GSRS diarrhea score compared to placebo treatment. The composition of the microbiota shifted between the start of the study and after two weeks of consumption of the products, but no differences between the intervention groups were observed, possibly due to dietary guidelines that subjects had to adhere to during the study. In conclusion, consumption of the whey protein concentrate by healthy adults did not reduce diarrhea scores in an E. coli infection model compared to a whey hydrolysate placebo control.

Underlying Causes and Co-existence of Malnutrition and Infections: An Exceedingly Common Death Risk in Cancer

In nutrition science, malnutrition is a state of imbalance between intake and the needs of the organism, leading to metabolic changes, impaired physiological functions, and weight loss. Regardless of the countless efforts being taken and researched for years, the burden of malnutrition is still alarming and considered a significant agent of mortality across the globe. Around 45% of 12 million children deaths (0–5 years old) annually are due to malnutrition, mostly from developing countries. Malnutrition develops associations with other infections and leads to substantial clinical outcomes, such as mortality, more visits to hospitals, poor quality of life and physical frailty, and socioeconomic issues. Here, in this review, we intend to provide an overview of the current burden, underlying risk factors, and co-existence of malnutrition and other infections, such as cancer. Following the rising concern of the vicious interplay of malnutrition and other medical illnesses, we believed that this narrative review would highlight the need to re-make and re-define the future strategies by giving comprehensive and sustainable programs to alleviate poverty and combat the rampant infectious diseases and those nutrition-related health problems. Furthermore, the study also raises the concern for hospitalized malnourished cancer patients as it is crucially important to knowledge the caregiver healthcare staff for early interventions of providing nutritional support to delay or prevent the onset of malnutrition.

Mortality in children with cerebral palsy in rural Bangladesh: a population-based surveillance study

AIM

To determine the mortality rate, immediate cause of death (CoD), and predictors of death in children with cerebral palsy (CP) in rural Bangladesh.

METHOD

We carried out a prospective population-based surveillance study of children with CP aged 0 to 18 years registered with the Bangladesh Cerebral Palsy Register (BCPR) between January 2015 and December 2016, with subsequent follow-up until December 2017. Verbal autopsy was applied to assign immediate CoD. Crude mortality rates, hazard ratios of death, and survival probabilities were estimated.

RESULTS

Twenty-nine of the 678 children in the BCPR died during the study period, resulting in a crude mortality rate of 19.5 per 1000 person-years of observation (total follow-up duration 1486.8 person-years; mean 2y [standard deviation 6mo]). The leading immediate CoD was meningitis (n=9) and pneumonia (n=8). Survival probability and hazard ratio of death was significantly associated with age, Gross Motor Functional Classification System level, and associated impairments. Severe underweight and/or severe stunting was significantly overrepresented among deceased children than others in the cohort (p<0.05) when compared with the World Health Organization reference population.

INTERPRETATION

The majority of deaths were due to potentially preventable causes. The life expectancy of these children could have been extended by ensuring primary healthcare and nutritional supplementation.

WHAT THIS PAPER ADDS

Mortality rate in children with cerebral palsy (CP) in rural Bangladesh is 19.5 per 1000 person-years. The majority of children with CP died from potentially preventable and treatable conditions. Motor severity, associated impairments, and malnutrition make children with CP vulnerable to premature death in rural Bangladesh.

The Association of Nutrition Status Expressed as Body Mass Index z Score With Outcomes in Children With Severe Sepsis: A Secondary Analysis From the Sepsis Prevalence, Outcomes, and Therapies (SPROUT) Study

OBJECTIVES

The impact of nutrition status on outcomes in pediatric severe sepsis is unclear. We studied the association of nutrition status (expressed as body mass index z score) with outcomes in pediatric severe sepsis.

DESIGN

Secondary analysis of the Sepsis Prevalence, Outcomes, and Therapies study. Patient characteristics, ICU interventions, and outcomes were compared across nutrition status categories (expressed as age- and sex-adjusted body mass index z scores using World Health Organization standards). Multivariable regression models were developed to determine adjusted differences in all-cause ICU mortality and ICU length of stay by nutrition status.

SETTING

One-hundred twenty-eight PICUs across 26 countries.

PATIENTS

Children less than 18 years with severe sepsis enrolled in the Sepsis Prevalence, Outcomes, and Therapies study (n = 567).

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Nutrition status data were available for 417 patients. Severe undernutrition was seen in Europe (25%), Asia (20%), South Africa (17%), and South America (10%), with severe overnutrition seen in Australia/New Zealand (17%) and North America (14%). Severe undernutrition was independently associated with all-cause ICU mortality (adjusted odds ratio, 3.0; 95% CI, 1.2-7.7; p = 0.02), whereas severe overnutrition in survivors was independently associated with longer ICU length of stay (1.6 d; p = 0.01).

CONCLUSIONS

There is considerable variation in nutrition status for children with severe sepsis treated across this selected network of PICUs from different geographic regions. Severe undernutrition was independently associated with higher all-cause ICU mortality in children with severe sepsis. Severe overnutrition was independently associated with greater ICU length of stay in childhood survivors of severe sepsis.

Follow-up between 6 and 24 months after discharge from treatment for severe acute malnutrition in children aged 6-59 months: A systematic review

BACKGROUND

Severe acute malnutrition (SAM) is a major global health problem affecting some 16.9 million children under five. Little is known about what happens to children 6-24 months post-discharge as this window often falls through the gap between studies on SFPs and those focusing on longer-term effects.

METHODS

A protocol was registered on PROSPERO (PROSPERO 2017:CRD42017065650). Embase, Global Health and MEDLINE In-Process and Non-Indexed Citations were systematically searched with terms related to SAM, nutritional intervention and follow-up between June and August 2017. Studies were selected if they included children who experienced an episode of SAM, received a therapeutic feeding intervention, were discharged as cured and presented any outcome from follow-up between 6-24 months later.

RESULTS

3,691 articles were retrieved from the search, 55 full-texts were screened and seven met the inclusion criteria. Loss-to-follow-up, mortality, relapse, morbidity and anthropometry were outcomes reported. Between 0.0% and 45.1% of cohorts were lost-to-follow-up. Of those discharged as nutritionally cured, mortality ranged from 0.06% to 10.4% at an average of 12 months post-discharge. Relapse was inconsistently defined, measured, and reported, ranging from 0% to 6.3%. Two studies reported improved weight-for-height z-scores, whilst three studies that reported height-for-age z-scores found either limited or no improvement.

CONCLUSIONS

Overall, there is a scarcity of studies that follow-up children 6-24 months post-discharge from SAM treatment. Limited data that exists suggest that children may exhibit sustained vulnerability even after achieving nutritional cure, including heightened mortality and morbidity risk and persistent stunting. Prospective cohort studies assessing a wider range of outcomes in children post-SAM treatment are a priority, as are intervention studies exploring how to improve post-SAM outcomes and identify high-risk children.

Protein Malnutrition Alters Tryptophan and Angiotensin-Converting Enzyme 2 Homeostasis and Adaptive Immune Responses in Human Rotavirus-Infected Gnotobiotic Pigs with Human Infant Fecal Microbiota Transplant

Malnutrition leads to increased morbidity and is evident in almost half of all deaths in children under the age of 5 years. Mortality due to rotavirus diarrhea is common in developing countries where malnutrition is prevalent; however, the relationship between malnutrition and rotavirus infection remains unclear. In this study, gnotobiotic pigs transplanted with the fecal microbiota of a healthy 2-month-old infant were fed protein-sufficient or -deficient diets and infected with virulent human rotavirus (HRV). After human rotavirus infection, protein-deficient pigs had decreased human rotavirus antibody titers and total IgA concentrations, systemic T helper (CD3⁺ CD4⁺) and cytotoxic T (CD3⁺ CD8⁺) lymphocyte frequencies, and serum tryptophan and angiotensin I-converting enzyme 2. Additionally, deficient-diet pigs had impaired tryptophan catabolism postinfection compared with sufficient-diet pigs. Tryptophan supplementation was tested as an intervention in additional groups of fecal microbiota-transplanted, rotavirus-infected, sufficient- and deficient-diet pigs. Tryptophan supplementation increased the frequencies of regulatory (CD4⁺ or CD8⁺ CD25⁺ FoxP3⁺) T cells in pigs on both the sufficient and the deficient diets. These results suggest that a protein-deficient diet impairs activation of the adaptive immune response following HRV infection and alters tryptophan homeostasis.
