Model-based standardization using multiple imputation.

Background: When studying the association between treatment and a clinical outcome, a parametric multivariable model of the conditional outcome expectation is often used to adjust for covariates. The treatment coefficient of the outcome model targets a conditional treatment effect. Model-based standardization is typically applied to average the model predictions over the target covariate distribution, and generate a covariate-adjusted estimate of the marginal treatment effect.

Tris(1,3-dichloro-2-propyl) phosphate induces endoplasmic reticulum stress and mitochondrial-dependent apoptosis in mouse spermatocyte GC-2 cells.

Tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) is a frequently detected organophosphorus flame retardants (OPFRs) in various environmental media, and has been evidenced as reproductive toxicity. However, its adverse effects on spermatogenic cells are unknown. In this study, mouse spermatocyte GC-2spd (GC-2) cells were selected as an in vitro model, and the impact of mitochondrial structure and function, endoplasmic reticulum (ER) stress, cell apoptosis and the related molecular mechanisms were investigated.

Metagenomic next-generation sequencing helped diagnose scrub typhus without eschar: A case report.

Background: Scrub typhus is caused by Orientia tsutsugamushi. Clinical manifestations include fever, rash, eschar at the bite site, and other non-specific flu-like symptoms. The eschar is a dark, scab-like area at the bite site, and is the typical lesions that prompts a diagnosis of O.

Traditional postpartum practices and rituals: a qualitative systematic review.

Many cultures around the world observe specific postpartum rituals to avoid ill health in later years. This qualitative systematic review examined the literature describing traditional postpartum practices from 51 studies in over 20 different countries. Commonalities were identified in practices across cultures.
