Clinical care advice for monitoring of islet autoantibody positive individuals with presymptomatic type 1 diabetes

Diabetes Metab Res Rev. 2024 Feb;40(2):e3777. doi: 10.1002/dmrr.3777. ABSTRACT BACKGROUND/AIM: Type 1 diabetes is an autoimmune disease that involves the development of autoantibodies against pancreatic islet beta-cell antigens, preceding clinical diagnosis by a period of preclinical disease activity. As screening activity to identify autoantibody-positive individuals increases, a rise in presymptomatic…

Antecedents of maternal pregnancy-related anxiety trajectories: The FinnBrain birth cohort study

Acta Psychiatr Scand. 2024 Feb 18. doi: 10.1111/acps.13671. Online ahead of print. ABSTRACT OBJECTIVE: Little is known about the normative courses of pregnancy-related anxiety throughout pregnancy and their antecedents. We examined in a large scale pregnancy cohort which potentially distinct trajectories of pregnancy-related anxiety across pregnancy can be identified, and…

Small Non-Coding RNAs in Male Reproduction

Semin Reprod Med. 2024 Feb 12. doi: 10.1055/s-0044-1779726. Online ahead of print. ABSTRACT Male reproductive functions are strictly regulated in order to maintain sperm production and fertility. All processes are controlled by precise regulation of gene expression, which creates specific gene expression programs for different developmental stages and cell types,…

Metabolic syndrome and epigenetic aging: a twin study

Int J Obes (Lond). 2024 Jan 25. doi: 10.1038/s41366-024-01466-x. Online ahead of print. ABSTRACT BACKGROUND: Metabolic syndrome (MetS) is associated with premature aging, but whether this association is driven by genetic or lifestyle factors remains unclear. METHODS: Two independent discovery cohorts, consisting of twins and unrelated individuals, were examined (N…

Negative associations between maternal prenatal hair cortisol and child socioemotional problems

Psychoneuroendocrinology. 2024 Jan 4;162:106955. doi: 10.1016/j.psyneuen.2023.106955. Online ahead of print. ABSTRACT Maternal prenatal distress can participate in the programming of offspring development, in which exposure to altered maternal long-term cortisol levels as measured by hair cortisol concentrations (HCC) may contribute. Yet, studies investigating whether and how maternal prenatal HCC associates…

X-chromosome and kidney function: evidence from a multi-trait genetic analysis of 908,697 individuals reveals sex-specific and sex-differential findings in genes regulated by androgen response elements

Nat Commun. 2024 Jan 18;15(1):586. doi: 10.1038/s41467-024-44709-1. ABSTRACT X-chromosomal genetic variants are understudied but can yield valuable insights into sexually dimorphic human traits and diseases. We performed a sex-stratified cross-ancestry X-chromosome-wide association meta-analysis of seven kidney-related traits (n = 908,697), identifying 23 loci genome-wide significantly associated with two of the…

Trans-ancestral genome-wide association study of longitudinal pubertal height growth and shared heritability with adult health outcomes

Genome Biol. 2024 Jan 16;25(1):22. doi: 10.1186/s13059-023-03136-z. ABSTRACT BACKGROUND: Pubertal growth patterns correlate with future health outcomes. However, the genetic mechanisms mediating growth trajectories remain largely unknown. Here, we modeled longitudinal height growth with Super-Imposition by Translation And Rotation (SITAR) growth curve analysis on ~ 56,000 trans-ancestry samples with repeated…

Association of long-term habitual dietary fiber intake since infancy with gut microbiota composition in young adulthood

J Nutr. 2024 Jan 12:S0022-3166(24)00027-0. doi: 10.1016/j.tjnut.2024.01.008. Online ahead of print. ABSTRACT BACKGROUND: Dietary fiber is an important health-promoting component of the diet, which is fermented by the gut microbes that produce metabolites beneficial for the host’s health. OBJECTIVE: We studied the associations of habitual long-term fiber intake from infancy…
