Eating disorders among people with and without type 1 diabetes: incidence and treatment in a nationwide population-based cohort.
Diabetologia
January 2025
Department of Public Health, University of Helsinki, Helsinki, Finland.
Aims/hypothesis: Eating disorders are over-represented in type 1 diabetes and are associated with an increased risk of complications, but it is unclear whether type 1 diabetes affects the treatment of eating disorders. We assessed incidence and treatment of eating disorders in a nationwide sample of individuals with type 1 diabetes and diabetes-free control individuals.
Methods: Our study comprised 11,055 individuals aged <30 who had been diagnosed with type 1 diabetes in 1998-2010, and 11,055 diabetes-free control individuals matched for age, sex and hospital district.
Association of sleep duration and sleep disorders with post-stroke depression and all-cause and cardiovascular disease mortality in US stroke survivors: results from NHANES 2005-2018.

Background: Sleep disturbance is a common concern among stroke survivors, yet the association of sleep duration and sleep disorders with post-stroke depression and all-cause and cardiovascular disease (CVD) mortality remains elusive. We aimed to explore these associations using data from the National Health and Nutrition Examination Survey (NHANES).
Methods: Adult stroke survivors from NHANES 2005-2018 were included.
Development of differential sublaminar feedforward inhibitory circuits in CA1 hippocampus requires .

Pyramidal cells (PCs) in CA1 hippocampus can be classified by their radial position as deep or superficial and organize into subtype-specific circuits necessary for differential information processing. Specifically, superficial PCs receive fewer inhibitory synapses from parvalbumin (PV)-expressing interneurons than deep PCs, resulting in weaker feedforward inhibition of input from CA3 Schaffer collaterals. Using mice, we investigated mechanisms underlying CA1 PC differentiation and the development of this inhibitory circuit motif.

Article Synopsis
- Microbial metabolism is highly adaptable, allowing growth on varying carbon sources through fermentation and respiration.
- A mathematical framework was developed to analyze cellular resource allocation alongside redox chemistry, highlighting how metabolism balances carbon, electrons, and energy while treating biomass as both a product and catalyst for growth.
- The study found that proteins in microbes evolve to enhance redox matching, suggesting that genetic changes that may not benefit individual proteins can still be favored if they improve the overall fitness of the microbial population.
A mutant ASXL1-BAP1-EHMT complex contributes to heterochromatin dysfunction in clonal hematopoiesis and chronic monomyelocytic leukemia.

is one of the three most frequently mutated genes in age-related clonal hematopoiesis (CH), alongside and (. CH can progress to myeloid malignancies including chronic monomyelocytic leukemia (CMML) and is also strongly associated with inflammatory cardiovascular disease and all-cause mortality in humans. DNMT3A and TET2 regulate DNA methylation and demethylation pathways, respectively, and loss-of-function mutations in these genes reduce DNA methylation in heterochromatin, allowing derepression of silenced elements in heterochromatin.
