Keynote webinar | Spotlight on sleep in brain health

LIVE: Thursday 2nd May 2024, 18:00-19:30 (CEST)

Quality sleep is essential for health. But what happens to our brains when sleep patterns are disturbed? Join our experts to explore the interplay between sleep disruption and neurological diseases, and the questions that you need to be asking your patients to help you prevent the harmful effects of sleep deprivation.

Abstract

Purpose

Our aim was to evaluate the association between the different degree of obesity and prosthetic joint infections (PJIs) after total hip replacement (THR) by performing a meta-analysis.

Methods

PubMed, Cochrane library and Embase databases up to May, 2014 were retrieved for identifying relevant studies. Relative risk (RR) and their 95 % confidence intervals (CIs) were used as effect sizes.

Results

A total of 15 articles were included in this meta-analysis. The overall analyses showed that the risk of PJIs in the BMI ≥ 30 group and in BMI ≥ 40 group were significantly higher than that in the BMI < 30 group. As well, the prospective pooled results showed that overweight and obesity could significantly increase the incidence of PJIs.

Conclusions

Our meta-analysis indicates that all of obesity levels can significantly increase the risk of PJIs. However, further studies with more strict design are need in the future.
