Single-blinded, stratified, dose ranging trial to assess pharmacokinetics and identify optimal dose of vitamin B12 in pregnancy in Tanzania.

BACKGROUND: Vitamin B12 is an essential cofactor for two enzymes that have critical functions in pregnancy, both for maternal health and fetal development. However, the optimal supplemental dosage and its correlation with vitamin B12 status during pregnancy remain inadequately understood due to limited data. METHODS: This is a single-blinded, stratified, dose-ranging trial of vitamin B12 supplementation that will be conducted at the Ifakara Health Institute Bagamoyo Clinical Trial Unit in Bagamoyo, Tanzania. We will enroll 40 pregnant participants (gestational age 25-28 weeks) and 10 non-preg

Incriminating vectors of deer malaria (Plasmodium odocoilei) at a Florida deer farm.

BACKGROUND: Plasmodium odocoilei, the only nonhuman Plasmodium parasite of native mammals in North America, infects white-tailed deer (WTD) throughout the eastern USA. Although deer malaria is not a significant cause of disease in healthy deer, infection with P. odocoilei may increase susceptibility to infection with and mortality due to epizootic hemorrhagic disease virus in deer fawns. The incrimination of the vector(s) of deer malaria is an essential step in developing management plans for reducing the incidence of deer malaria. METHODS: At a deer farm in Gadsden County, FL, with previousl

Responsiveness of the Serum Carbon Isotope Ratio to Dietary Added Sugar Reduction in a Randomized Controlled Trial among Youth with Steatotic Liver Disease.

BACKGROUND: The carbon isotope ratio (CIR) has been proposed as a biomarker for added sugar intake, but few studies have been conducted in youth, with data from controlled, feeding studies particularly lacking.

Correlating food and nutritional patterns with cancers in the pediatric oncology population at two specialized hospitals in Tanzania.

BACKGROUND: This study of nutritional patterns in relation to cancers among pediatric oncology population in Tanzania was motivated by the lack of up-to-date information about the nutritional practices, the controversy around the importance of nutritional support and the lack of consistent nutritional criteria among pediatric oncology populations. METHODS: A survey study in two cancer referral hospitals of children diagnosed with any cancers, aged between 1 and 17 years inclusive and being eligible for enteral feeding included 131 children. Their demographic, nutritional, feeding and cancer p

Chrononutrition in the Prevention and Management of Metabolic Disorders: A Literature Review.

BACKGROUND: The concept of time-restricted eating (TRE) or time-restricted feeding (TRF) promotes daily periods of feeding and fasting to determine whole-body physiology. Chronic misalignment of circadian rhythms or chrono-disruption is related to an increased risk of diverse metabolic disorders. The progression of non-communicable diseases seems to be affected by the timing of meals. As a result, intermittent fasting is a promising approach for their management. The aim of the present literature review is to examine and scrutinize the TRE protocols in the fields of prevention and management o

Infant diet quality index predicts nutrients of concern and ultra-processed food intake in low-income children in the United States.

BACKGROUND: Diet quality during infancy can influence nutrient intake and ultra-processed foods (UPFs) consumption throughout later childhood. OBJECTIVES: This study investigated the predictive validity of Infant Diet Quality Index (IDQI) scores from 0 to 1 y of age and consumption of select nutrients and UPFs at different time points in low-income children aged 2-5 y. METHODS: Dietary surveys and 24-h dietary recalls collected between ages 0 and 12 months from 2613 Special Supplemental Women, Infants, and Children Infant Toddler Feeding Practices Study-2 participants were used to assess inf

Caregivers' perceptions of factors influencing undernutrition among under five in Ubungo, Dar es Salaam, Tanzania.

BACKGROUND: Undernutrition in children is predominantly linked to lack of a balanced diet resulting from inadequate nutrition intake. This form of malnutrition remains a leading cause of morbidity and mortality under-five children, especially prevalent in low-income countries. Understanding the specific factors contributing to undernutrition among this group, particularly those associated with caregivers, is vital yet insufficiently explored. Therefore, this study aimed to investigate and evaluate caregivers' perceptions regarding the factors influencing under-nutrition among children under-fi

Growth and body composition of infants born moderate-to-late preterm fed a protein- and mineral-enriched postdischarge formula compared with a standard term formula until 6 months corrected age, a randomized controlled trial.

BACKGROUND: Infants born moderate-to-late preterm (i.e., 32 wk-35 wk 6 d gestation) are, analogous to those born very preterm, at risk of later obesity, hypertension, and diabetes. Appropriate early life nutrition is key for ensuring optimal growth and body composition, thereby mitigating potential cardiometabolic risks. OBJECTIVES: We aimed to compare growth and body composition between infants born moderate-to-late preterm fed isocaloric but protein- and mineral-enriched postdischarge formula (PDF) or standard term formula (STF) until 6 mo corrected age (CA; i.e., after term equivalent age

Comparison of growth patterns in the first year of life between term small for gestational age and appropriate for gestational age South Indian infants.

BACKGROUND: Early life growth trajectories of Indian small for gestational age (SGA) infants are sparse. This study aimed to compare longitudinal growth in appropriate for gestational age (AGA) and SGA infants during their first year of life. METHODS: Apparently healthy term infants (52 SGA, 154 AGA) were recruited at birth and followed up till 1 year. Parental, sociodemographic characteristics and feeding patterns were recorded. Anthropometric measurements were assessed at birth, 3, 6, 9 and 12 months of age; Z scores and growth velocity at 3-month intervals were computed. Longitudinal measu

Factors affecting infant feeding choices with a focus on barriers to exclusive breastfeeding in Western Jamaica: a qualitative study.

BACKGROUND: Despite the many benefits of exclusive breastfeeding to infants and mothers, only 33% of Jamaican infants are exclusively breastfed up to the recommend six months. This study was conducted to identify factors affecting mothers' feeding choices focusing on barriers to exclusive breastfeeding of infants six weeks to less than six months old. METHODS: A qualitative study consisting of four focus group discussion sessions was conducted among 22 mothers attending postnatal clinics in western Jamaica from May to August 2016. The transcripts were coded by three independent coders and con

Adjusting phosphate feeding regimen according to daily rhythm increases eggshell quality via enhancing medullary bone remodeling in laying hens.

BACKGROUND: Body phosphorus metabolism exhibits a circadian rhythm over the 24-h daily cycle. The egg laying behavior makes laying hens a very special model for investigating phosphorus circadian rhythms. There is lack of information about the impact of adjusting phosphate feeding regimen according to daily rhythm on the phosphorus homeostasis and bone remodeling of laying hens. METHODS AND RESULTS: Two experiments were conducted. In Exp. 1, Hy-Line Brown laying hens (n = 45) were sampled according the oviposition cycle (at 0, 6, 12, and 18 h post-oviposition, and at the next oviposition, res

Establishment of a nomogram model for predicting metabolic bone disease in preterm infants: A case‒control study.

OBJECTIVE: To investigate risk factors for metabolic bone disease (MBD) in preterm infants and establish a nomogram model for predicting MBD risk. METHODS: A total of 1104 preterm infants were enrolled, among whom 809 were included in the modelling set and 295 were included in the validation set. The modelling set was divided into MBD (n = 185) and non-MBD (n = 624) groups. A multivariate logistic regression analysis was used to investigate the independent risk factors for MBD. R software was used to plot the nomogram model, which was then validated by the data of the validation set. Receiver

The specific mitochondrial unfolded protein response in fast- and slow-twitch muscles of high-fat diet-induced insulin-resistant rats.

INTRODUCTION: Skeletal muscle insulin resistance (IR) plays an important role in the pathogenesis of type 2 diabetes mellitus. Skeletal muscle is a heterogeneous tissue composed of different muscle fiber types that contribute distinctly to IR development. Glucose transport shows more protection in slow-twitch muscles than in fast-twitch muscles during IR development, while the mechanisms involved remain unclear. Therefore, we investigated the role of the mitochondrial unfolded protein response (UPRmt) in the distinct resistance of two types of muscle in IR. METHODS: Male Wistar rats were divi

No NLRP3 inflammasome activity in kidney epithelial cells, not even when the NLRP3-A350V Muckle-Wells variant is expressed in podocytes of diabetic mice.

BACKGROUND: The NLRP3 inflammasome integrates several danger signals into the activation of innate immunity and inflammation by secreting IL-1β and IL-18. Most published data relate to the NLRP3 inflammasome in immune cells, but some reports claim similar roles in parenchymal, namely epithelial, cells. For example, podocytes, epithelial cells critical for the maintenance of kidney filtration, have been reported to express NLRP3 and to release IL-β in diabetic kidney disease, contributing to filtration barrier dysfunction and kidney injury. We questioned this and hence performed independent ver

[Long noncoding RNA H19 promotes vascular calcification by repressing the Bax inhibitor 1/optic atrophy 1 pathway].

OBJECTIVE: To investigate whether long noncoding RNA H19 (lncRNA H19) induces vascular calcification by promoting calcium deposition, osteogenic differentiation and apoptosis via inhibiting the Bax inhibitor 1/optic atrophy 1 (BI-1/ OPA1) pathway. METHODS: β-glycerophosphate and calcium chloride were used to induce calcification in rat vascular smooth muscle cells (VSMCs), and the effects of siH19, alone or in combination with BI-1 or OPA1 knockdown, on calcification of the cells were investigated. Osteogenic differentiation was assessed by measuring Runt-related transcription factor 2 (Runx-

Utility of dual energy CT angiography in the evaluation of acute non-variceal gastrointestinal hemorrhage: comparison with digital subtraction angiography.

PURPOSE: To evaluate the utility of dual energy CT angiography (DECTA) in acute non-variceal gastrointestinal hemorrhage (ANVGIH) compared to digital subtraction angiography (DSA) as gold standard. MATERIALS AND METHODS: 111 Patients (mean age: 39.2 years; 94 males) of ANVGIH who underwent both DECTA and DSA between January 2016 and September 2021 were included. Virtual monochromatic (VM) images at 10 keV increments from 40 to 70 keV and blended (120kVp equivalent) images of arterial phase of DECTA were evaluated independently by two readers blinded to DSA information. Quantitative analysis i

Circulating progranulin in human infants: relation to prenatal growth and early postnatal nutrition.

BACKGROUND: Progranulin (PGRN) displays pleiotropic biological functions and has been proposed as a biomarker for metabolic diseases. We longitudinally assessed PGRN concentrations in infants born appropriate (AGA) or small for gestational age (SGA), the latter being at risk for obesity and type 2 diabetes, especially if they experience an excessive postnatal catch-up in weight and are formula-fed (FF). METHODS: The study population consisted of 183 infants who were exclusively breast-fed [(BF), AGA, n = 66; SGA, n = 40], or FF (AGA, n = 31; SGA, n = 46) over the first 4 months. Assessments i

Lipid profile after omega-3 supplementation in neonates with intrauterine growth retardation: a randomized controlled trial.

BACKGROUND: Neonates with intrauterine growth restriction (IUGR) have a high lipid profile that predisposes them to cardiovascular disease later in life. We aimed to evaluate the effect of omega 3 supplementation on serum leptin level, lipid profile, and growth in neonates with IUGR. METHODS: This clinical trial was conducted on 70 full-term neonates with IUGR. Neonates were randomly divided into two equal groups; the treatment group: received omega 3 supplement (40 mg/kg/day) for 2 weeks after the establishment of full feeding, and the control group, who were followed up to full feeding with

Associations between human milk oligosaccharides and infant growth in a Bangladeshi mother-infant cohort.

BACKGROUND: We aimed to estimate associations between human milk oligosaccharides (HMOs) and infant growth (length-for-age (LAZ) and weight-for-length (WLZ) z-scores) at 12 months postnatal age. METHODS: In this secondary analysis of data from a maternal vitamin D trial in Dhaka, Bangladesh (N = 192), absolute concentrations of HMOs were measured in 13 ± 1 week(s) postpartum milk samples, infant anthropometric measurements were obtained soon after birth and at 12 months postpartum, and infant feeding was classified during 6 months postpartum. Associations between individual HMOs or HMO groups
