There was a significant difference in the sex ratio between offspring from fresh and from vitrification-thawed blastocyst transfer. The live birth sex ratio influenced by the blastocyst-stage embryo transfer correlated with top-quality embryo morphology.

Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.
Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.
Background And Aims: Body composition parameters associated with aerobic fitness, mirrored by maximal oxygen consumption (V̇Omax), have recently gained interest as indicators of physical efficiency in facioscapulohumeral dystrophy (FSHD). Bioimpedance analysis (BIA) allows a noninvasive and repeatable estimate of body composition but is based on the use of predictive equations which, if used in cohorts with different characteristics from those for which the equation was originally formulated, could give biased results. Instead, the phase angle (PhA), a BIA raw bioelectrical parameter reflecting body fluids distribution, could provide reliable data for such analysis.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia around the world with an increased risk of a broad spectrum of adverse comorbidities and death. Whether cardiovascular health (CVH) is associated with AF development remains unclear.
Methods: 238,420 participants without cardiovascular disease at baseline were selected from the UK Biobank study cohort from 2006 to 2010.

The purpose was to summarize the studies examining knee strength in young athletes and provide valuable insights into the magnitude of changes in knee flexion and extension strength during the transition from pre-puberty to puberty among male and female athletes. The literature search was conducted through Cochrane Library, Embase, PubMed, Web of Science. Cohen's effect size (ES) and 95% confidence intervals (CIs) were computed using a random effects model.

Background: We aimed to investigate if iron deficiency was associated with infection susceptibility in a large cohort of healthy individuals.
Study Design And Methods: The Danish Blood Donor Study is a national ongoing prospective study of blood donors. We included 94,628 donors with 338,290 ferritin measurements from March 2010 to October 2022.
