The popularity of Olympic-style weightlifting in fitness routines is growing, but participating in these exercises with improper technique places lifters at increased risk for injury. Fitness training professionals have developed multiple teaching strategies, but have not subjected these strategies to systematic evaluation, particularly with novice lifters. Two strategies recommended by professional training organizations are akin to forward and backward chaining, which have been shown effective at teaching other novel, complex behaviors. The present study compared these forward- and backward-chaining-like strategies to teach novice lifters "the clean" and "the snatch," two Olympic weightlifting movements frequently incorporated into high-intensity training programs. Participants performed lifts taught with forward chaining more accurately than lifts taught with backward chaining.

Background: Understanding the epidemiological parameters and transmission dynamics of Lassa fever, a significant public health threat in west Africa caused by the rodent-borne Lassa virus, is crucial for informing evidence-based interventions and outbreak response strategies. Therefore, our study aimed to collate and enhance understanding of the key epidemiological parameters of Lassa fever.
Methods: We conducted a systematic review, searching PubMed and Web of Science for peer-reviewed studies published from database inception up to June 13, 2024, to compile and analyse key epidemiological parameters, mathematical models, and outbreaks of Lassa fever.

Aim: The aim of this literature review was to explore women's experiences of their intimate and sexual relationships during menopause.
Background: Evidence shows that the menopause transition can be a difficult time for women due to symptoms of menopause. There is little research evidence about how menopause-related symptoms impact women's intimate and sexual relationships.

Problem: Currently there is a lack of clear guidance to underpin postnatal listening services for women who have had a traumatic or difficult birth.
Background: Postnatal listening (or birth reflections) services are important to help women review their birth and ask questions about their care, but currently there is no clear guidance on how these services should be provided.
Aim: To synthesise existing evidence on postnatal listening services for women following a traumatic or negative childbirth experience.

Road corridors contain countless sources of distraction, each carrying the potential to draw drivers' eyes and minds off roads, thus increasing the risk of a crash. While the impact of billboards on driver distraction has received considerable attention, empirical data for other types of roadside advertising signs is very limited. Furthermore, the existing research examining other potential external sources of distraction is fragmentary, which makes it difficult to develop evidence-based road safety policies to mitigate risk.
