Assessment of proximate composition, mineral element profile and antioxidant properties of the edible oyster mushroom grown in Bangladesh

Mushrooms have been considered as a therapeutic and nutrient-rich foods in numerous countries for years due to their significant levels of nutritional components, vitamins and antioxidants. This study aimed to assess the nutrient content, mineral profile and antioxidant properties of eight different kinds of oyster mushrooms (Pleurotus sp.) cultivated in Bangladesh. The mushrooms were analyzed for their moisture content, carbohydrates, proteins, fats, fibers, ash, vitamin A, and vitamin C. The mineral profile included sodium, potassium, calcium, and iron, as well as heavy metals. Antioxidant activities were evaluated through various methods, including phenolic, flavonoid and tannin content, total antioxidant activity, and DPPH (2,2-diphenyl-1-picryl-hydrazyl) scavenging capacity. The findings revealed that the mushrooms under investigation were high in carbohydrate (ranges between 45.25 and 63.22 g/100 g), protein (23.48–33.16 g/100 g) and dietary fiber (42.87–52.31 g/100 g). The total ash content was ranged from 7.28 to 9.41 g/100 g and vitamin C content was 0.020–0.416 mg/100 g. Interestingly, all of the mushrooms had a lower fat content (0.91–2.6%). The mineral profile indicated the presence of varying concentrations of essential elements. Hazardous heavy metals, such as Cd and Cr were not detected in the mushroom sample, while As and Pb were detected but lower than the tolerance levels. The oyster mushrooms exhibited high levels of phenolic, flavonoid, and tannin contents, as well as significant antioxidant capacity. A methanol extract of the oyster mushrooms exhibited scavenging activity against DPPH in a dose dependent manner with the highest capacity (75.4%) obtained at a concentration of 0.2 mg/ml. Our result suggests that these studied oyster mushrooms could be a good source of nutrition and antioxidants, which could be used as functional foods.

Longitudinal trajectories of the overall and regional body composition between severe acute malnourished and well-nourished children of Rohingya refugee camps

ObjectivesThe present study aimed to observe how body composition differs between severe acute malnutrition (SAM) (treated with ready-to-use therapeutic food, RUTF) and well-nourished children.MethodsA longitudinal investigation was conducted among well-nourished and SAM children of 6-59 months in Rohingya refugee camps. These two groups (350 children in each group) of children were observed over 12 weeks and individual data were collected during admission, follow-up visits, and at the time of discharge. Anthropometric information was collected following standard procedures. The thicknesses of the biceps, triceps, subscapular, and supra iliac skinfolds were measured using a Herpenden-type skinfold caliper. Separate linear mixed models were conducted to assess associations of the independent variables (i.e., group and time) with each of the dependent variables (i.e., biceps, triceps, subscapular, supra-iliac skinfold thickness (ST), fat mass (FM), and fat-free mass (FFM)).ResultsBoth in well-nourished and SAM children, the mean biceps, triceps, subscapular, and supra-iliac ST, FM, and FFM increased over the 12 weeks. The increase in biceps ST was significantly faster in the SAM children compared to the well-nourished children (difference in slope = 0.366 mm every four weeks; p < 0.001). The increment rate in triceps ST was also faster in the SAM children compared to the well-nourished children (difference in slope = 0.430 mm every four weeks; p < 0.001). Moreover, the pace of increase in subscapular (difference in slope = 0.027 mm every four weeks; p < 0.001), and supra-iliac (difference in slope = 0.211 mm every four weeks, p < 0.001) ST was also significantly higher in the SAM group. Similarly, the change in FM (difference in slope = 0.065 kg every four weeks, p < 0.001) and FFM (difference in slope = 0.152 kg every four weeks, p = 0.023) was also significantly faster in SAM children compared to the well-nourished children over the treatment period. Furthermore, the girls gained significantly higher triceps ST, subscapular ST, FM, and FFM compared to the boys.ConclusionThe benefit of RUTF was evident from this longitudinal study in the recovery of FM and FFM contents among the SAM children of Rohingya refugee camps.

Perceptions of stakeholders on the use of a simplified, combined protocol for treatment of acute malnutrition in Central African Republic.

Treatment of acute malnutrition requires novel approaches to improve coverage, reduce costs and improve the efficiency of standard protocols that separate the management of moderate acute malnutrition (MAM) and severe acute malnutrition (SAM). The use of simplified, combined protocols to treat both MAM and SAM has drawn research and policy interest among global, regional and national stakeholders. However, the perspectives of local communities and health care workers regarding the use of protocols to treat acute malnutrition in a routine health care system are generally lacking. This was a cross-sectional mixed-methods study aimed at assessing the perceptions of different stakeholders on the use of a simplified, combined protocol in two districts in the Central African Republic. Most of the respondents preferred the simplified, combined protocol over the standard protocol. They generally agreed that the protocol was easy to understand, allowed more children to receive treatment and was effective in treating acute malnutrition. The protocol modifications were well received, including the expanded admission criteria, use of mid-upper arm circumference (MUAC) only for admission and discharge criteria and reduced and simplified ready-to-use therapeutic food quantity to treat MAM and SAM. Some caregivers expressed concern with the use of MUAC only to declare recovery, flagging that underlying illnesses could still be present. The caregivers recommended the provision of other food basket interventions to improve the treatment. The support by caregivers and health care workers on the idea of training community health volunteers to treat acute malnutrition points to the potential of scaling up decentralized treatment to increase coverage in remote areas.

Ready-to-use therapeutic food as a promising therapy for the prevention and cure of undernutrition in pre-school children: A review

The nutritional status of pre-school children is a reflection of health of children in the world and forms the basis for the development of success-oriented interventional programs. This study indicates the prevalence of under-nutrition in under five children in the world, Africa and Nigeria. It also showed the prevalence of under-nutrition in the six geopolitical regions in Nigeria, with the Northern regions reported to have the highest burden of under-nutrition compared to the other regions due to several factors such as inadequate breast feeding, lack of access to healthcare, lack of clean water, armed conflict, inadequate dietary intake, inappropriate feeding, foetal growth restriction, inadequate sanitation, lack of parental education, large family size, incomplete vaccination, poverty and low socio-economic status and desire to have more children. Several nutritional interventions have been put in place to prevent and cure under-nutrition in pre-school children, which include Promotion of exclusive breastfeeding, Micronutrient supplementation, Food fortification, Nutrition education, Complimentary feeding, and Cash transfer programs, Ready-to-use therapeutics foods (RUTF), Nutritional rehabilitation centers, Parenteral nutrition, and Nutritional counseling and education. However, RUTF has been reported to have an effective intervention in the prevention and treatment of severe acute malnutrition (SAM) in pre-school children. It is an energy dense, shelf stable and ready to eat food which composed of peanut butter, sugar, full fat milk and mineral-vitamin premix. Other plant-based ingredients such as chickpea, soybean, sesame, maize, oats, sorghum and sunflower oil have also, been used in the production of RUTF and reported to be effective for complete recovery of SAM children.

Arrhythmia occurs as a common heart vascular disease. Functional food is a rich source of natural compounds with significant pharmacological, The aim of this paper is to explore its effect on arrhythmia. By reviewing the literature and summarising the findings, we described the role of functional foods in the alleviation of cardiac arrhythmias from different perspectives. Our study shows that functional foods have anti-arrhythmic effects through modulation of ion channels, oxidative stress, and Calmodulin-dependent protein kinase II. We summarize the mechanism of arrhythmia inhibition by the active ingredients of medicinal diets in this review article, intending to provide research ideas for dietary therapy to regulate arrhythmia.

An Acceptability of locally produced Ready-to-Use Therapeutic Food (RUTF) among children aged 2-4 years in Sri Lanka

Although child wasting is preventable, it is a significant public health problem in Sri Lanka. Imported ready-to-use therapeutic food (RUTF), called BP-100, is part of the locally used treatment of severe acute wasting. However, Sri Lanka has faced economic barriers in providing this product. Two RUTF bars were developed in our laboratory based on global nutrient and other specifications (RUTF-1 and RUTF-2). Nutrient and microbiological analyses were within acceptable limits and shelf life was determined. This observational study was conducted to test the acceptability of locally produced RUTFs among children aged 2-4 years old, a first step in its possible use in place of imported versions. 56 children aged 2-4 years old in two preschools located in poor urban settings were included. These two RUTF bars and BP-100 were given to the children for a total period of three weeks (3 days of each product), with 3 to 4 days of interval in between. At the beginning, weight and height of the children were measured. A five-response hedonic scale was used to test acceptability. Mean daily intakes, and any apparent adverse effects were recorded. A taste test on the acceptability of RUTF and BP-100 among mothers or guardians was carried out on the last day of the trial. The colour, taste, smell, and texture of both RUTF bars were compared to BP-100. Overall acceptability of RUTF-1 (p=0.000) and RUTF-2 (p=0.02) was observed compared to BP-100 among both children and mothers. No adverse effects were reported. Further analysis indicated that there was no significant difference between locally produced RUTFs and BP-100 on acceptability in relation to sex, age, wasting, or stunting; however, a difference was noted related to ethnicity (p=0.000). In conclusion, locally produced RUTFs are as acceptable as BP-100. There is a need to assess the effectiveness of RUTFs while building partnerships with the food industry for sustainable production.

β-galactosidase producing Lactiplantibacillus spp in intestinal microbiome mouse diarrhea model and metagenomic analyses

Probiotics have attained significant interest in recent years as a result of their gut microbiome modulation and gastrointestinal health benefits. Numerous fermented foods contain LAB with GRAS grade and probiotic bacteria. The most promising isolates with high potentiality were selected for 16S rRNA gene sequence analysis and identified as Lactiplantibacillus plantarum, L. fermentum, L. pentosus and Lactiplantibacillus sp. The present study was conducted to determine the gastrointestinal symptoms after the consumption of milk and dairy products, lactose intolerance status using mice model. Post-weaning Balb/c mice were orally administered with probiotic bacteria to assess their efficiency in reducing lactose intolerance symptoms. They exhibited significantly reduced total feces weight and slower intestinal motility and they efficiently alleviated diarrhea symptoms within 6 h of lactose challenge in lactose intolerance-induced mice. Next generation sequence analysis was performed using intestinal content of model treated with L. plantarum GV54 and GV64, the intestinal bacterial diversity was studied using Illumina NGS analysis (16S rRNA hypervariable regions [V3 and V4]). NGS report confirmed the existence of the dominant phyla of the gut microbiome in mice are Bacteroidetes, Firmicutes and Proteobacteria. Due to the influence of the probiotic bacteria in the model group (GV54 and GV64), maximum abundance of phylum Firmicutes were observed when compared to the control group, whereas control group showed more abundance of phylum Bacteriodetes. However, the relative abundance of Bacteroidetes in the model group was decreased and Firmicutes abundance was increased. This indicates the genus abundance of Lactobacillus (Lactiplantibacillus) species or Lactiplantibacillus plantarum GV54 and GV64 bacteria. After treatment with probiotic bacteria Lactobacillus (Lactiplantibacillus) species, the probiotic bacterial abundance was increased consequently genera Helicobacter, Clostridiales unclassified and Desulfovibrio were decreased in the model groups. Probiotic bacteria has a positive impact on the regulation of intestinal microbial diversity in the tested mice system and it reflects that the intestinal microbiota of mice is dynamic and has positive impact on gut health. Considering this point, it is possible to promote Lactiplantibacillus spp. as probiotics and therapeutic food development at industrial scale.

The study of Thai herbal plant extract as a potential therapeutic food ingredient for preventing the effects of airborne pollutants via in vitro model

Thai herbal plant is known as medicinal plant material for several treatments of diseases particularly non-communicable diseases (NCDs). This work aimed to investigate the potentiality of three plant extracts, including Bat flower (TCE), Vietnamese Coriander (POE), and Indian Pennywort (Centell), which can be a therapeutic food ingredient, in the protection of blood vessels caused by the effect of airborne through the in vitro model. The vascular smooth muscle cell (VSMC), A7r5 rat aortic cell, was used for cell culture and determined their activity after being treated with dust and plant extracts at different concentrations. The dust was prepared at 0-400 μg/mL, and the plant extracts were prepared as powder by freeze dryer before further use. The toxicity test, antioxidant activity, and cell apoptosis as well as wound healing properties were examined. The results showed the POE was highest the antioxidant activity (TPC: 1156.02±35.78 mg gallic acid/g sample and DPPH: 949.45±31.97 μmol Trolox/g sample) when compared to TCE and Centell (p<0.05). The maximum concentration of plant extracts treated cells was not over 500 μg/mL for cell toxicity. The VSMC cell apoptosis depended on increasing the dust concentration manner. There was a positive effect of plant extracts on wound repair in the blood vessels after being treated with TCE at a concentration of 100 μg/mL. According to the results, it could be suggested that plant extracts, especially TCE can be a food ingredient that plays a vital role in preventing the blood vessel from the airborne effects caused by PM10 receiving. Also, these data help and be useful for healthy food or therapeutic food development for reducing the risk factor of arteriosclerotic effects.

Cronobacter sakazakii lysozyme inhibitor LprI mediated by HmsP and c-di-GMP is essential for biofilm formation and virulence.

Cronobacter sakazakii poses a significant threat, particularly to neonates and infants. Despite its strong pathogenicity, understanding of C. sakazakii biofilms and their role in infections remains limited. This study investigates the roles of HmsP and c-di-GMP in biofilm formation and identifies key genetic and proteomic elements involved. Gene knockout experiments reveal that HmsP and c-di-GMP are linked to biofilm formation in C. sakazakii. Comparative proteomic profiling identifies the lysozyme inhibitor protein LprI, which is downregulated in hmsP knockouts and upregulated in c-di-GMP knockouts, as a potential biofilm formation factor. Further investigation of the lprI knockout strain shows significantly reduced biofilm formation and decreased virulence in a rat infection model. Additionally, LprI is demonstrated to bind extracellular DNA, suggesting a role in anchoring C. sakazakii within the biofilm matrix. These findings enhance our understanding of the molecular mechanisms underlying biofilm formation and virulence in C. sakazakii, offering potential targets for therapeutic intervention and food production settings.IMPORTANCECronobacter sakazakii is a bacterium that poses a severe threat to neonates and infants. This research elucidates the role of the lysozyme inhibitor LprI, modulated by HmsP and c-di-GMP, and uncovers a key factor in biofilm formation and virulence. The findings offer crucial insights into the molecular interactions that enable C. sakazakii to form resilient biofilms and persist in hostile environments, such as those found in food production facilities. These insights not only enhance our understanding of C. sakazakii pathogenesis but also identify potential targets for novel therapeutic interventions to prevent or mitigate infections. This work is particularly relevant to public health and the food industry, where controlling C. sakazakii contamination in powdered infant formula is vital for safeguarding vulnerable populations.

Locally Prepared Therapeutic Food for Treatment of Severely Underweight Children in Rural India: An Interventional Prospective Controlled Community-Based Study with Long Follow-Up:-'SAMMAN' Trial.

Severely underweight (SUW) children contribute significantly to under-five mortality and morbidity. There are WHO guidelines for the management of severe acute malnutrition but no specific guidelines for SUW management. The objectives were to achieve a recovery rate of 30% at 90 days of treatment for severe underweight (SUW) children aged 6-60 months, compare changes in weight-for-age Z (WAZ) scores, growth patterns, and case fatality rates between intervention and reference arms (RA), and reduce the prevalence of SUW in the intervention arm (IA). The target of a 30% recovery rate was achievable and significant based on our past research conducted in similar settings. Design: A prospective controlled community-based, longitudinal, two arms (IA, RA), intervention study with long follow-up was conducted between January 2011 and October 2023. Primary care for participants from 14 villages in rural Melghat, India. The study participants included SUW children aged 6-60 months and age-matched (±2 weeks) normal controls. The SAMMAN (Acronym for SAM-Management) intervention was comprised of local therapeutic food-micronutrient (LTF-MN) therapy for 90 days, intensive behavior change communication, infection treatment, and quarterly anthropometric records. SUW recovery, growth patterns, case fatality rate, prevalence at 90 days of therapy and at 60 months of age, and survival until early adolescence were assessed. ANCOVA analysis was used to obtain changes in Z-scores. In the IA, the recovery rate was 36.8% at 90 days and 78.2% at 60 months of age. The mean difference in change in WAZ scores between the intervention arm and the reference arm was statistically significant (p < 0.0001). Growth patterns were similar between the two arms up to early adolescence. The SUW case fatality rate was significantly lower in the IA (0.9%) as compared to 4.62% in the RA at 60 months (p = 0.022). The reduction in SUW prevalence in intervention villages was higher than in the control villages (p < 0.001). The cost of management per SUW child was 3888 INR (47 USD) less than RUTF. The SAMMAN intervention is safe and cost-effective for significantly improving WAZ scores, sustainable, and hence replicable in resource-limited areas.

DHA-enriched phosphatidylserine ameliorates cyclophosphamide-induced liver injury via regulating the gut-liver axis

ObjectiveThis study explores the therapeutic effects and mechanisms of DHA-enriched phosphatidylserine (DHA-PS) on liver injury induced by cyclophosphamide (CTX) in mice, focusing on the gut-liver axis. MethodsA mouse model was established by administering CTX (80 mg/kg) intraperitoneally for 5 days. DHA-PS (50 or 100 mg/kg) was administered for the next 7 days to assess its reparative impact on liver damage. ResultsThe findings revealed significant improvements in liver biochemical indices, inflammatory markers, and oxidative stress levels in the mice treated with DHA-PS. Through non-targeted metabolomics analysis, DHA-PS mitigated CTX-induced metabolic disruptions by modulating lipid, amino acid, and pyrimidine metabolism. Immunofluorescence analysis further confirmed that DHA-PS reduced the expression of liver-associated inflammatory proteins by inhibiting the TLR4/NF-κB pathway. Additionally, DHA-PS restored the intestinal barrier, evidenced by adjustments in the levels of intestinal lipopolysaccharide (LPS), secretory immunoglobulin A (sIgA), and tight junction proteins (Claudin-1, Occludin, and ZO-1). It also improved gut microbiota balance by enhancing microbial diversity, increasing beneficial bacteria, and altering community structures. ConclusionThese results suggest that DHA-PS could be a potential therapeutic agent or functional food for CTX-induced liver injury through its regulation of the gut-liver axis.

The levels, single and multiple health risk assessment of 23 metals in enteral nutrition formulas

Enteral nutrition formulas are products that provide macro and micronutrients to patients who cannot receive their nutrition orally. In this study, the levels of 23 metals known to have potential health risks were determined by inductively coupled plasma mass spectrometry in a total of 28 enteral nutrition formula. Metal exposure was calculated according to three different daily energy intake scenarios (Scenario 1 = 50% oral nutrition + 50% enteral nutrition formula, Scenario 2 = 25% oral nutrition + 75% enteral nutrition formula and Scenario 3 = 100% enteral nutrition formula) and evaluated in terms of non-carcinogenic health risks. The mean levels of Fe, Co, Ni, Cu, Zn, Mo, Se, Li, Be, V, As, Sr, Ag, Cd, Sb, Ba, La, Hg and Pb in the samples analyzed were determined 12,000 ± 3300, 64 ± 1.6, 10 ± 13, 1300 ± 400, 8500 ± 2500, 75 ± 30, 61 ± 21, 0.34 ± 0.36, 0.05 ± 0.08, 7.3 ± 2, 1.6 ± 0.6, 457 ± 166, 0.02 ± 0.1, 0.14 ± 0.12, 0.01 ± 0.1, 74 ± 103, 0.63 ± 0.4, 0.05 ± 0.03 and 0.14 ± 0.7 μg/L. These metals were considered safe in terms of non-carcinogenic health risks when analyzed individually. However, when the target hazard quotient values of all metals were evaluated together, hazard index values were higher than the reference value of 1, for both men and women, indicating potential health risks.

EnvZ/OmpR Controls Protein Expression and Modifications in Cronobacter sakazakii for Virulence and Environmental Resilience.

Cronobacter sakazakii is a notorious foodborne opportunistic pathogen, particularly affecting vulnerable populations such as premature infants, and poses significant public health challenges. This study aimed to elucidate the role of the envZ/ompR genes in environmental tolerance, pathogenicity, and protein regulation of C. sakazakii. An envZ/ompR knockout mutant was constructed and assessed for its impact on bacterial growth, virulence, environmental tolerance, and protein regulation. Results demonstrate that deletion of envZ/ompR genes leads to reduced growth rate and attenuated virulence in animal models. Additionally, the knockout strain exhibited compromised environmental tolerance, particularly in desiccation and oxidative stress conditions, along with impaired adhesion and invasion abilities in epithelial cells. Proteomic analysis revealed significant alterations in protein expression and phosphorylation patterns, highlighting potential compensatory mechanisms triggered by gene deletion. Furthermore, investigation into protein deamidation and glucose metabolism uncovered a link between envZ/ompR deletion and energy metabolism dysregulation. Interestingly, the downregulation of MalK and GrxC proteins was identified as contributing factors to altered desiccation tolerance and disrupted redox homeostasis, respectively, providing mechanistic insights into the phenotypic changes observed. Overall, this study enhances understanding of the multifaceted roles of envZ/ompR in C. sakazakii physiology and pathogenesis, shedding light on potential targets for therapeutic intervention and food safety strategies.

The relationship between energy provided and growth during severe wasting treatment.

Treatment of severe acute malnutrition aims at producing quick catch-up growth in children to decrease their short-term mortality risk. The extent to which catch-up growth is influenced by the amount of energy provided is unclear. This study assessed whether energy provided at admission is associated with catch-up ponderal growth among children with mid-upper arm circumference (MUAC) < 115 mm at admission. We conducted a secondary data analysis an operational cohort in Mali. The children were treated with a simplified protocol providing 1000 kcal/day of therapeutic food until MUAC ≥ 115 mm was achieved for two consecutive weeks and 500 kcal/day thereafter until discharge with MUAC ≥ 125 mm for two consecutive weeks. Linear mixed-effects regression models were fitted to assess the relationship between energy provided at admission (kcal/kg/day) with weight gain velocity (g/kg/day) (primary outcome), change in MUAC -for-age z-score and change in weight-for-age z-score. Unadjusted models and models adjusted for sex, age, seasonality and MUAC at admission were fitted. Both models included the study site as a random effect. A 10 kcal/kg/day increase in energy provided at admission was associated with increments in all outcomes; for weight gain velocity, the mean (95%CI) increment was 0.340 [0.326, 0.354] g/kg/day and 0.466 [0.446, 0.485] g/kg/day in the unadjusted and adjusted analysis, respectively. A positive relationship exists between energy provided at admission and catch-up ponderal growth in children with MUAC < 115 mm treated using a simplified protocol. Determining the ideal weight gain rate remains essential for assessing the benefits and risks of increased energy intake during treatment.

Volume-based enteral feeding for ward patients with acute neurological conditions: a pilot prospective cohort study.

Patients requiring enteral nutrition (EN) after neurological insults experience feeding interruptions, contributing to inadequate nutrition delivery. This prospective cohort study investigated if volume-based enteral feeding (VBF) improved the delivery of prescribed EN volume in ward patients with acute neurological conditions. Over two sequential periods, the usual care group received standard continuous rate-based feeding, and the intervention group received VBF with bi-daily EN rate adjustments to achieve target daily volume. The primary outcome was percentage of prescribed daily EN formula volume delivered. Differences in energy and protein provision, weight, malnutrition and safety were explored. An evaluation survey captured nurse acceptability of the protocol. The intervention group (n = 32) achieved greater median interquartile range (IQR) EN adequacy of prescribed volume at 92% (88-97) compared to 67% (54-78) for usual care (n = 35) (p < 0.001). VBF compared to rate-based feeding resulted in patients receiving more kilojoules (131 [121-138] kJ/kg vs. 84 [64-99] kJ/kg; p < 0.001) and protein (1.3 [1.2-1.5] g/kg vs. 0.9 [0.6-1.1] g/kg; p < 0.001). There were no differences in gastrointestinal intolerance between groups. Compliance to the VBF protocol was 90%, and 78% of staff reported high confidence using the protocol. The intervention group had less median weight loss at discharge (-1.4 [0.1 to -4.3] kg) than usual care (-3.6 [-1.3 to 8.4] kg; p < 0.011), but no differences in malnutrition status were observed. A VBF protocol delivered greater EN volume, energy and protein following neurological injury. The VBF protocol was feasible with high acceptability from nursing staff.

Dietary diversity and associated factors among households and children in internally displaced person camps in Southern Somalia: A cross-sectional study.

The study aimed to assess household and child dietary diversity in Southern Somalia by identifying determinants of adequate dietary diversity in three internally displaced person (IDP) camps in Baidoa, Dayniile and Dharkanley. A total of 1655 female main caregivers with 2370 children (6-59 months old) were included. Data on household dietary diversity score and child dietary diversity score indicators were collected from all households. The questionnaire was read face-to-face to the female main caregivers. Multivariate logistic regression analysis was performed to identify factors associated with adequate dietary diversity, which was defined as the consumption of at least four food groups within 24 h before the survey. The proportion of households achieving adequate HDDS was high in all locations 95.8%, 96.9% and 89.0% in Baidoa, Dharkanley and Dayniile, respectively, and the total adequate household dietary diversity score (AHDDS) was 95.6%. The proportion of adequate child dietary diversity score (ACDDS) was achieved in 63.5%, 8.5% and 38.3%. The main factors associated with AHDDS were larger household size, greater wealth, attendance of antenatal care (ANC) and joint decision-making between husband and wife, while factors associated with ACDDS included ANC attendance, age, the consumption of ready-to-use therapeutic food and deworming tablets. These findings can guide future programmes and policies aimed at improving maternal and child nutrition in IDP camps in Somalia. By tackling these diverse factors, a promising pathway emerges to enhance the nutritional welfare of both households and children in IDP camps.

First occurrence and risk assessment of microplastics in enteral nutrition formulas

Occurrence and characteristics of microplastics were evaluated in enteral nutrition formulas, for the first time. A total of 30 samples belonging to 9 brands were analysed. Physical and chemical characteristics of microplastics were identified by stereomicroscopy and micro-raman spectroscopy, respectively. The mean number of microplastics was 45 ± 63 MP/L. Two different shapes of microplastics were detected with fibres (62%) being the most common microplastics followed by fragments (38%). The most common color of microplastics was black (37%) followed by blue (26%), orange (15%), green (7%), red (7%), grey (4%) and multicolor (4%). The length of microplastics ranged from 10 to 2086 μm with an average of 548 ± 526 μm. Estimated mean daily microplastic intake for four different scenarios varied between 24 to 61 and 30 to 76 MPs/day for women and men, respectively. The mean polymer hazard index and microplastic load index levels were calculated as 380 and 1.30, respectively. The results of this study showed that microplastics are prevalent in enteral nutrition products. The presence of polymers with high hazard risk scores in enteral nutrition formulas may pose a risk to the health of patients with special nutritional needs.
