The analysis of copper (Cu) and zinc (Zn) along with their major serum carriers, albumin (Alb) and ceruloplasmin (Cp), could provide information on the capacity of humans to maintain homeostasis of metals (metallostasis). However, their relationship with aging, sex, body mass index, as well as with nutritional and inflammatory markers was never investigated in a large-scale study. Here, we report results from the European large-scale cross-sectional study MARK-AGE in which Cu, Zn, Alb, Cp, as well as nutritional and inflammatory parameters were determined in 2424 age-stratified participants (35-75 years), including the general population (RASIG), nonagenarian offspring (GO), a well-studied genetic model of longevity, and spouses of GO (SGO). In RASIG, Cu to Zn ratio and Cp to Alb ratio were higher in women than in men. Both ratios increased with aging because Cu and Cp increased and Alb and Zn decreased. Cu, Zn, Alb, and Cp were found associated with several inflammatory as well as nutritional biomarkers. GO showed higher Zn levels and higher Zn to Alb ratio compared to RASIG, but we did not observe significant differences with SGO, likely as a consequence of the low sample size of SGO and the shared environment. Our results show that aging, sex, body mass index, and GO status are characterized by different levels of Cu, Zn, and their serum carrier proteins. These data and their relationship with inflammatory biomarkers support the concept that loss of metallostasis is a characteristic of inflammaging.

Purpose: This study investigated elite German athletes to (1) assess their serum 25(OH)D levels and the prevalence of insufficiency, (2) identify key factors influencing serum 25(OH)D levels, and (3) analyze the association between serum 25(OH)D levels and handgrip strength.
Methods: In this cross-sectional study, a total of 474 athletes (231 female), aged 13-39 years (mean 19.3 years), from ten Olympic disciplines were included.

This study reviews the prevalence of copper (Cu) deficiency in patients for metabolic and bariatric surgery (MBS), as well as the long-term outcomes related to the prevalence of Cu deficiency after undergoing MBS. A systematic literature search and meta-analysis were conducted in PubMed, Web of Science, and Scopus for articles published by August 31, 2024. The search terms included metabolic and bariatric surgery, weight loss surgery, metabolic surgery, obesity surgery, sleeve gastrectomy, gastric banding, gastric bypass, duodenal switch, duodenojejunal bypass, copper, copper deficiency, and hypocuposemia.

Background: Complementary feeding is crucial for infant growth, but poor hygiene during this period increases the risk of malnutrition and illness. In Ethiopia, national data on hygiene practices during complementary feeding, particularly among mothers of children aged 6-24 months, is limited. This study aims to synthesize existing data through a systematic review and meta-analysis to evaluate the status of hygiene practices and identify key influencing factors, informing public health strategies to improve child health outcomes.

Background: Modern dietary trends have led to an increase in foods that are relatively high in n-6 polyunsaturated fatty acids (PUFAs) and low in n-3 PUFAs. We previously reported that the offspring of mother mice that consumed a diet high in n-6 linoleic acid (LA) and low in n-3 α-linolenic acid (ALA), hereinafter called the LA/ALA diet, exhibit behavioral abnormalities related to anxiety and feeding.
Objective: We currently lack a comprehensive overview of the behavioral abnormalities in these offspring, which was investigated in this study.

This study aimed to examine the relationship between eating behavior, nutritional status and mental health. It is a cross-sectional study conducted on a sample of 360 healthy individuals aged 19-64 years. The General Health Questionnaire (GHQ-12) was used to evaluate mental health and the Three-Factor Eating Scale (TFEQ-R21) was used to assess eating behavior.
