On the Identifiability of Genetic Parameters for Growth in Mice With a Massively Deep Pedigree

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In models with direct and maternal genetic effects, structural features of the data are a potential source of bias and low accuracy of estimates for genetic covariance parameters. One of the well‐known reasons for such poor practical identifiability is the lack of dams with own observations.

Genetic Parameters of Resilience Indicators Across Growth in Beef Heifers and Their Associations With Weight, Reproduction, Calf Performance and Pre‐Weaning Survival

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In tropical extensive beef cattle systems, heifers raised on pasture are exposed to various environmental challenges that affect their growth and reproductive performance during the first breeding. Resilience indicators derived from deviations in longitudinal traits can quantify the magnitude of these challenges and the ability of an animal to

Multi‐Breed Genomic Predictions for Average Daily Gain in Three Italian Beef Cattle Breeds

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Marchigiana, Chianina, and Romagnola are three Italian autochthonous beef cattle breeds that have been historically selected for meat production. Recent advancements suggest that the use of genomic data and multi‐breed (MB) models to combine information from different breeds may help to increase the accuracies of genomic predictions, in ...

Childhood trauma, adolescent risk behaviours and cardiovascular health indices in the 2004 Pelotas Birth Cohort

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Childhood trauma has been associated with increased risk of substance use and poor sleep, with these factors linked to subsequent poor cardiovascular health. However, there has been little longitudinal research exploring these associations in adolescence, especially in low‐ and middle‐income countries (LMICs).

Bidirectional causal links between diabetes mellitus and autoimmune liver diseases: Insights from Mendelian randomization

open access: yesJournal of Diabetes Investigation, EarlyView.
This study employed a two‐sample Mendelian randomization approach to assess the causal relationship between autoimmune liver diseases (AILD) and diabetes mellitus. We found that genetic predispositions to primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) were significantly associated with an increased risk of type 1 diabetes ...
