Precision medicine in Fabry disease.

Nephrol Dial Transplant 2021 Jun;36(Supplement_2):14-23

Internal Medicine D, Department of Nephrology, Hypertension and Rheumatology, Interdisciplinary Fabry Center Münster, University Hospital Münster, Münster, Germany.

Fabry disease (FD) is a rare X-linked lysosomal storage disorder caused by mutations in the α-galactosidase A (GLA) gene, leading to a deficiency in α-galactosidase A. The lysosomal accumulation of glycosphingolipids, primarily globotriaosylceramide (Gb3) and its deacylated form, globotriaosylsphingosine (lyso-Gb3), results in progressive renal failure, cardiomyopathy associated with cardiac arrhythmia and recurrent cerebrovascular events, significantly limiting life expectancy in affected patients. In male patients, a definitive diagnosis of FD involves demonstrating a GLA deficiency in leucocytes. Read More

Variation in self-identified most stressful life event by outcome of previous pregnancy in a population-based sample interviewed 6-36 months following delivery.

Soc Sci Med 2021 Jun 16;282:114138. Epub 2021 Jun 16.

Department of Epidemiology, Rollins School of Public Health, Emory University, 1518 Clifton Rd, Atlanta, GA, 30322, United States.

The majority of health research uses a deductive approach to measure stressful life events, despite evidence that perception of what is stressful varies. The goal of this project was to 1) describe the distribution of self-identified most stressful life events in a cohort of women who experienced a perinatal loss (stillbirth or neonatal death) or live birth in the previous three years and 2) test how childhood adversity influences participant selection of their most stressful life event. We used data from 987 women (282 with stillbirth, 657 without loss, and 48 with a neonatal death in the first 28 days) in the Stillbirth Collaborative Research Network - OASIS (Outcomes after Study Index Stillbirth) follow-up study, a population-based sample set in five U.

Spatiotemporally flexible subnetworks reveal the quasi-cyclic nature of integration and segregation in the human brain.

Neuroimage 2021 Jun 18:118287. Epub 2021 Jun 18.

Department of Women's and Children's health, Karolinska Institutet, Sweden.

Though the organization of functional brain networks is modular at its core, modularity does not capture the full range of dynamic interactions between individual brain areas nor at the level of subnetworks. In this paper we present a hierarchical model that represents both flexible and modular aspects of intrinsic brain organization across time by constructing spatiotemporally flexible subnetworks. We also demonstrate that segregation and integration are complementary and simultaneous events. Read More
