Zinc is a cofactor for several enzymes involved in many metabolisms. Zinc deficiency induces various disorders such as acrodermatitis enteropathica, either inherited or acquired. We report three cases of premature infants (24-31 wks gestational age) with low birthweight (650 to 940 g) and enteropathy, two of whom presented with necrotizing enterocolitis. All infants were fed by total parenteral nutrition. At a chronological age ranging from 73 to 80 days, all infants developed a periorificial dermatitis. Before the onset of the first signs, they had received zinc supplementation ranging from 146% to 195% of the recommended dose (400 microg/kg/day). Increased zinc supplementation over a course of 6-18 days induced a complete resolution of symptoms in all cases. No abnormality in the neurologic examination and no recurrence were observed at the end of the zinc treatment. Low birthweight premature infants with enteropathy on total parenteral nutrition are at risk of developing zinc deficiency. The usual recommended zinc supplementation is probably insufficient for those infants. A delay in the diagnosis of zinc deficiency may lead to severe complications.

A New Conceptual Framework for Enhancing Vaccine Efficacy in Malnourished Children.

J Multidiscip Healthc

December 2024

Department of Epidemiology and Biostatistics, School of Public Health, University of Kinshasa, Kinshasa, Democratic Republic of the Congo.

Background: Malnourished children in low- and middle-income countries (LMICs) often exhibit reduced vaccine efficacy, particularly for oral vaccines like polio and rotavirus, due to impaired immune responses. Nutritional deficiencies, such as in vitamin A and zinc, along with environmental factors like poor sanitation, exacerbate this issue. Existing research has explored the individual impacts of malnutrition on vaccine outcomes, but a comprehensive framework that integrates nutritional, immune, and environmental factors has been lacking.

Bone morphogenetic proteins are essential for bone regeneration/fracture healing but can also induce heterotopic ossification (HO). Understanding accessory factors modulating BMP signaling would provide both a means of enhancing BMP-dependent regeneration while preventing HO. This study focuses on the ability of the collagen receptor, discoidin domain receptor 2 (DDR2), to regulate BMP activity.

Traumatic brain injury (TBI) presents significant risks concerning mortality and morbidity. Individuals who suffer from TBI may exhibit mood disorders, including anxiety and depression. Both preclinical and clinical research have established correlations between TBI and disturbances in the metabolism of amino acids, lipids, iron, zinc, and copper, which are implicated in the emergence of mood disorders post-TBI.

Article Synopsis
  • Multiple Sclerosis (MS) patients show significantly higher concentrations of heavy metals like arsenic, nickel, manganese, and zinc in their stool compared to healthy individuals, while levels of iron, lead, titanium, and tin are notably lower.
  • The study also reveals alterations in the gut microbiome of MS patients, with increased abundance of certain bacterial families indicative of potential changes associated with the disease.
  • The research highlights a novel approach by combining heavy metal measurement and gut microbiome analysis, suggesting new insights into the disease's pathogenesis and possible therapeutic strategies.

Enhanced peroxone reaction with amphoteric oxide modulation for efficient decontamination of challenging wastewaters: Comparative performance, economic evaluation, and pilot-scale implementation.

The peroxone reaction, a promising alternative technology for water treatment, is traditionally hampered by its restricted pH operational range and suboptimal oxidant utilization. In this study, we introduced a novel amphoteric metal oxide (ZnO)-regulated peroxone system that transcended the pH limitations of conventional peroxone processes. Our innovative approach exploited the unique properties of ZnO to regulate the reaction pathway of the traditional O/HO (or peroxymonosulfate, PMS) processes, resulting in a 52.
