Nail-plate combination constructs versus single traditional constructs for distal femur fractures: a systematic review and meta-analysis of comparative studies.

Objectives: Distal femur fractures (DFF) are frequently treated surgically with single traditional constructs (STC), such as with a lateral plate or intramedullary nail, although nail-plate combination constructs (NPCC) are gaining attention. The purpose of this study is to compare outcomes between NPCC and STC for surgical fixation of DFF to guide surgeon decision-making.

Methods: Data Sources: This study is a systematic review and meta-analysis using PubMed, CINAHL, MEDLINE, Web of Science, Science Direct, and SPORTDiscus from database inception until January 10th, 2024.

[Tribology in arthroplasty : Friction and wear, a key to a long lifetime].

This article is intended to highlight one of the key roles in endoprosthetic treatment with artificial implants and the extension of service life. Like every joint, artificial joints are subject to the physical laws of friction and wear-in short, tribology. Material pairings, surfaces and mechanisms of action in particular play a decisive role here.

Fast and furious: successful survival and resumption of meiosis in immature human oocytes vitrified and warmed using a short protocol.

Research Question: Can immature oocytes vitrified and warmed using a short protocol survive and resume meiosis?

Design: This study examined modifications of oocyte vitrification and warming protocols that reduce the length of exposure to vitrification and warming solutions. In total, 561 germinal vesicles and 218 metaphase I oocytes that were immature at oocyte retrieval were vitrified at room temperature for 2 min. Warming was performed at 37°C for 2 min.

Impact of time interval from cesarean delivery to frozen embryo transfer on reproductive and neonatal outcomes.

Objective: To evaluate differences in reproductive and neonatal outcomes on the basis of the time interval from cesarean delivery to subsequent frozen embryo transfer (FET).

Design: Retrospective cohort.

Setting: Multicenter fertility practice.

Mild obesity does not affect perinatal outcome in gestational carrier cycles.

Study Question: Does BMI of gestational carriers (GCs) affect perinatal outcomes after embryo transfer?

Summary Answer: Overweight and class I obesity in GCs does not affect the rate of good perinatal outcomes.

What Is Known Already: The use of GCs is increasing, but uniform guidance regarding optimal BMI for GCs is lacking. Women with obesity who conceive without fertility treatment or through autologous or donor in vitro fertilization are at higher risk of adverse maternal and fetal outcomes, but data on obesity in GCs are very limited.
