Lead has negative effect on cognitive functions in children. However, individuals differ in susceptibility. One possible explanation is a genetic predisposition. Polymorphisms in the B-aminolevulinic acid dehydratase (ALAD) and the vitamin D receptor (VDR) genes may modify lead metabolism and neurotoxicity, but information regarding the central nervous system is very limited. The aim of the study was to determine whether ALAD and VDR polymorphisms modify blood lead (B-Pb), and the association between B-Pb and cognitive function (IQ) in children. In 2007-2010 a cohort of 175 children (age 6-10 years, mean 7.8) was recruited in Southern Poland, tested for IQ (Wechsler intelligence scale) and analyzed for B-Pb (range 9.0-221; mean 46.6 mu g/L), ALAD (Rsal, Mspl) and VDR (Fokl, Bsml, Taql) polymorphisms. ALAD or VDR genotypes were not associated with B-Pb. B-Pb was non-significantly negatively associated with full scale IQ (r(S) = -0.11; P = 0.14), and significantly with performance subscale results (r(S) = -0.19; P = 0.01). The ALAD Rsal polymorphism modified the relationship between full scale IQ and B-Pb: Rsal T carriers had a steeper slope compared to CC homozygote carriers (beta coefficient -0.06 vs 0.32, respectively, P for interaction < 0.001, adjusted for the child's age, mother's education and family income). This means that with increasing B-Pb with 1 mu g/L,T carriers demonstrate 0.06 score lower IQ. For the VDR Bsml, B carriers had a steeper slope than the bb homozygotes carriers (beta coefficient -0.08 vs 0.16, respectively, P for interaction = 0.001), and similar effect was found for Taql t carriers vs TT homozygotes (P for interaction = 0.02). For ALAD Mspl and VDR Fokl there was no significant modification. The ALAD Rsal, VDR Bsml and Taql polymorphisms modified the relationship between IQ and B-Pb. Hence, there is a fraction of the population, which is particularly sensitive to lead neurotoxicity. (C) 2011 Elsevier Inc. All rights reserved.

Association of Metabolically Healthy and Unhealthy Obesity Phenotypes with Oxidative Stress Parameters and Telomere Length in Healthy Young Adult Men. Analysis of the MAGNETIC Study

Mateusz Lejawa, Kamila Osadnik, Tadeusz Osadnik, Natalia Pawlas

Summary: This study found associations between oxidative stress, metabolic health, and telomere length in both healthy and unhealthy individuals. Total oxidation status, total antioxidant capacity, and telomere length were significantly linked with metabolically unhealthy obesity. The findings suggest that obesity can lead to telomere shortening through metabolic disturbances and oxidative stress associated with MetS. Further research is needed to explore these pathways in young individuals with different metabolic health statuses.

Summary: This study found an association between cadmium exposure and the risk of developing or exacerbating symptoms of inflammatory arthritis (IA). High levels of blood cadmium were linked to an increased risk of IA, as well as elevated levels of oxidative damage marker and cyclooxygenase-2, and frequent consumption of offal. Cadmium exposure was also related to disease symptoms onset in IA patients, decreased levels of anti-inflammatory interleukin 10, and increased disease activity.

A fatal case of poisoning with a cathinone derivative: α-PiHP and its postmortem distribution in body fluids and organ tissues

Paulina Wachholz, Rafal Celinski, Beata Bujak-Gizycka, Rafal Skowronek, Natalia Pawlas

Summary: This article presents a case of death caused by alpha-PiHP, a popular cathinone derivative. The analysis of toxicological results, autopsy, histopathological findings, and crime-scene information confirmed fatal intoxication with alpha-PiHP as the cause of death. Alpha-PiHP and its metabolite (OH-alpha-PiHP) were detected and quantified in various postmortem materials, making this the first case of determination of these substances in postmortem specimens. The authors believe that a database of alpha-PiHP and its metabolite concentrations can be useful in interpreting fatal cases.

The Link between Iron Turnover and Pharmacotherapy in Transplant Patients

Marcin Delijewski, Aleksandra Barton, Beata Maksym, Natalia Pawlas

Summary: Iron is a crucial transition metal in physiological processes, but it can also be toxic due to its involvement in free radical formation. Impaired iron metabolism leads to iron deficiency, anemia, and iron overload, with different prevalences in transplant patients. Limited knowledge exists on iron metabolism in lung graft recipients and donors, complicated further by the potential impact of drugs. This overview highlights the importance of understanding iron turnover in transplant patients and assessing drug effects on iron metabolism for perioperative treatment in transplantology.

Summary: COVID-19 has raised concerns about the adverse effects of sanitizers and disinfectants on human health. This study assessed the global health effects of these products and found that detergents, alcohol-based substances, and chlorinated compounds were the most prevalent chemical agents. Skin and respiratory effects were the most frequently reported health issues. The study highlights the need for increased awareness programs about the potential side effects of sanitizers and disinfectants during viral epidemics.
