Prevalence of autism diagnosis has historically differed by demographic factors. Using data from 8224 participants drawn from the Environmental influences on Child Health Outcomes (ECHO) Program, we examined relationships between demographic factors and parent-reported autism-related traits as captured by the Social Responsiveness Scale (SRS; T score > 65) and compared these to relations with parent-reported clinician diagnosis of ASD, in generalized linear mixed effects regression analyses. Results suggested lower odds of autism diagnosis, but not of SRS T > 65, for non-Hispanic Black children (adjusted odds ratio [OR] = 0.

Network meta-analysis is a powerful tool to synthesize evidence from independent studies and compare multiple treatments simultaneously. A critical task of performing a network meta-analysis is to offer ranks of all available treatment options for a specific disease outcome. Frequently, the estimated treatment rankings are accompanied by a large amount of uncertainty, suffer from multiplicity issues, and rarely permit possible ties of treatments with similar performance.

Red blood cell (RBC) metabolism regulates hemolysis during aging in vivo and in the blood bank. However, the genetic underpinnings of RBC metabolic heterogeneity and extravascular hemolysis at population scale are incompletely understood. Based on the breeding of 8 founder strains with extreme genetic diversity, the Jackson laboratory diversity outbred population can capture the impact of genetic heterogeneity in like fashion to population-based studies.

Article Synopsis
  • - Glucose-6-phosphate dehydrogenase (G6PD) deficiency, affecting 500 million people, impairs red blood cell antioxidant functions, raising the risk of hemolysis during oxidative stress, particularly during exercise.
  • - A study using mice with a specific G6PD variant showed that, despite lower enzyme activity, these mice had better exercise performance and improved heart function post-exercise compared to normal mice.
  • - Analysis revealed enhanced mitochondrial function and changes in energy metabolism and protein turnover, indicating that G6PD-deficient individuals might have a metabolic advantage during exercise, challenging existing beliefs about hemolytic risks.

Genetic mutations in genes regulating plasma testosterone in men may interfere with effective erythropoiesis, and may result in red blood cell (RBC) dysfunction and hemolysis. The aim of this study was to identify genetic polymorphisms in male donors that regulate plasma testosterone and impact RBC survival in cold storage and after transfusion. We evaluated nine single nucleotide polymorphisms (SNPs) previously reported to be associated with circulating testosterone in male plasma.

Background: Sickle cell disease (SCD) is a Mendelian disorder characterized by a point mutation in the β-globin gene that leads to sickling of erythrocytes. Several studies have shown that absolute neutrophil count is strongly associated with clinical severity of SCD, suggesting an apparent role of white blood cells (WBC) in SCD pathology. However, the mechanism by which genetic variants lead to WBC count differences in SCD patients remains unclear.

Article Synopsis
  • Cocaine is a commonly abused drug among people living with HIV, negatively affecting their health by slowing down the decline of viral production after starting antiretroviral therapy and leading to higher viral loads and faster disease progression.
  • The study focused on 434 women with varying ancestry participating in a national cohort study, analyzing the impact of cocaine use on the HIV latent reservoir in their CD4+ T-cells.
  • Results showed that current and prior cocaine users have significantly larger HIV latent reservoir sizes compared to non-users, highlighting the need for more research on cocaine's effects on women's HIV outcomes.

This paper serves as a Part II follow-up of our research investigations performed on the molecular structures of silver(I)-fluoride (SF) and diammine-silver(I) fluoride (SDF) complexes in solution-based commercial products for clinical application, their precise chemical compositions, and their nature in aqueous solution, the latter including rapid fluoride-exchange processes at the silver(I) ion centre monitored by F NMR analysis (Part I). Part I of this series also explores the mechanisms of action (MoA) of these complexes, and is therefore largely focused on their chemical reactions with constituents of human saliva, which has access to their sites of application. Such reactions were found to slowly promote the generation of potentially physiologically-active Ag/AgCl nanoparticles from primarily-generated discoloured silver(I) chloride (AgCl) precipitates, a process involving salivary electron-donors such as thiocyanate and L-cysteine.

Mature red blood cells (RBCs) lack mitochondria and thus exclusively rely on glycolysis to generate adenosine triphosphate (ATP) during aging in vivo or storage in blood banks. Here, we leveraged 13,029 volunteers from the Recipient Epidemiology and Donor Evaluation Study to identify associations between end-of-storage levels of glycolytic metabolites and donor age, sex, and ancestry-specific genetic polymorphisms in regions encoding phosphofructokinase 1, platelet (detected in mature RBCs); hexokinase 1 (HK1); and ADP-ribosyl cyclase 1 and 2 (CD38/BST1). Gene-metabolite associations were validated in fresh and stored RBCs from 525 Diversity Outbred mice and via multi-omics characterization of 1,929 samples from 643 human RBC units during storage.

Article Synopsis
  • The study investigates the molecular structure, composition, and interactions of silver(I)-diammine fluoride (SDF) and silver(I)-fluoride (SF) solutions, which are used in treating dental caries, highlighting the lack of prior research in this area.
  • Advanced techniques such as high-resolution NMR spectroscopy and SEM analyses revealed differences in the fluoride exchange dynamics of SDF and SF, along with the generation of silver chloride nanoparticles (CSNPs) when treated with human saliva.
  • Results suggest that the SDF product contains high levels of fluoride and ammonia, and that CSNPs formed from the interaction of these solutions with saliva incorporate various biomolecules, indicating a complex interplay when used in dental treatment.
