BMIgap: a new tool to quantify transdiagnostic brain signatures of current and future weight.

Understanding the neurobiological underpinnings of weight gain could reduce excess mortality and improve long-term trajectories of psychiatric disorders. We used support-vector machines and whole-brain voxel-wise grey matter volume to generate and validate a BMI predictor in healthy individuals (N = 1504) and applied it to individuals with schizophrenia (SCZ,N = 146), clinical high-risk states for psychosis (CHR,N = 213) and recent-onset depression (ROD,N = 200). We computed BMIgap (BMI -BMI ), interrogated its brain-level overlaps with SCZ and explored whether BMIgap predicted weight gain at 1- and 2-year follow-up.

The acute effect of high-dose supplemental oxygen on haemodynamics assessed by echocardiography in patients with pulmonary vascular disease living in Quito at 2850 m: a randomized, single-blind, placebo-controlled crossover trial.

Aims: More than 220 Mio people live at altitudes above 2000 m, many of whom have pre-existing chronic diseases, including pulmonary vascular diseases (PVDs) such as pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH). We investigated the acute effects of high-dose supplemental oxygen on pulmonary haemodynamics assessed by echocardiography in patients with PVD permanently living at 2850 m.

Methods And Results: In a randomized, single-blind, placebo-controlled crossover trial, patients with PVD diagnosed with PAH or CTEPH were allocated to receive 10 L/min supplemental oxygen (FiO ≈ 95%) and placebo air administered via a facial mask with reservoir near their living altitude in Quito at 2850 m (FiO0.

CGC1, a new reference genome for .

The original 100.3 Mb reference genome for , generated from the wild-type laboratory strain N2, has been crucial for analysis of since 1998 and has been considered complete since 2005. Unexpectedly, this long-standing reference was shown to be incomplete in 2019 by a genome assembly from the N2-derived strain VC2010.

Robust sex determination in the Caenorhabditis nigoni germ line.

Sexual characteristics and reproductive systems are dynamic traits in many taxa, but the developmental modifications that allow change and innovation are largely unknown. A leading model for this process is the evolution of self-fertile hermaphrodites from male/female ancestors. However, these studies require direct analysis of sex-determination in male/female species, as well as in the hermaphroditic species that are related to them.

Blood Pressure Monitoring and Knowledge in the First Year after a Hypertensive Disorder of Pregnancy.

In the first year postpartum, hypertension is a leading cause of morbidity and mortality, particularly for those with hypertensive disorders of pregnancy (HDPs). Given that timely recognition of hypertension is key to reducing short- and long-term cardiovascular risk, we assessed knowledge of when to seek medical attention for blood pressure (BP) elevations and rates of BP measurement in the first year postpartum. This was a secondary analysis of a cohort of 405 primiparas who enrolled in a randomized trial during pregnancy.
