The chest response of the human body has been studied for several load conditions, but is not well known in the case of steering wheel rim-to-chest impact in heavy goods vehicle frontal collisions. The aim of this study was to determine the response of the human chest in a set of simulated steering wheel impacts. PMHS tests were carried out and analysed. The steering wheel load pattern was represented by a rigid pendulum with a straight bar-shaped front. A crash test dummy chest calibration pendulum was utilised for comparison. In this study, a set of rigid bar impacts were directed at various heights of the chest, spanning approximately 120mm around the fourth intercostal space. The impact energy was set below a level estimated to cause rib fracture. The analysed results consist of responses, evaluated with respect to differences in the impacting shape and impact heights on compression and viscous criteria chest injury responses. The results showed that the bar impacts consistently produced lesser scaled chest compressions than the hub; the Middle bar responses were around 90% of the hub responses. A superior bar impact provided lesser chest compression; the average response was 86% of the Middle bar response. For inferior bar impacts, the chest compression response was 116% of the chest compression in the middle. The damping properties of the chest caused the compression to decrease in the high speed bar impacts to 88% of that in low speed impacts. From the analysis it could be concluded that the bar impact shape provides lower chest criteria responses compared to the hub. Further, the bar responses are dependent on the impact location of the chest. Inertial and viscous effects of the upper body affect the responses. The results can be used to assess the responses of human substitutes such as anthropomorphic test devices and finite element human body models, which will benefit the development process of heavy goods vehicle safety systems.

Background: Hand, foot, and mouth disease (HFMD) is a prevalent infectious condition in children. This study aimed to assess the regulatory effects of Re-Du-Ning on the intestinal microflora of pediatric patients with HFMD.
Methods: Fecal samples were collected from children affected by HFMD, who were diagnosed at the traditional Chinese medicine pediatrics outpatient and emergency departments of Liuzhou Women and Children's Healthcare Hospital, as well as from healthy children undergoing physical examinations at the same hospital during the same period.
Impact of an electronic surveillance system on compliance with isolation precaution measures: an interrupted time series study.

Background: Electronic surveillance systems (ESSs) may assist infection prevention and control (IPC) teams in detecting and monitoring patients infected or colonised by pathogens to prevent healthcare-associated infections. We aimed to assess the impact of implementing an ESS on compliance with isolation precaution measures for bacterial infections or colonizations.
Methods: A quasi-experimental before-after study was conducted using interrupted time series analysis from 1 March 2018 to 31 July 2024 at the University Hospital of Nancy (France).
The impact of co-housing on murine aging studies.

Analysis of preclinical lifespan studies often assume that outcome data from co-housed animals are independent. In practice, treatments, such as controlled feeding or putative life-extending compounds, are applied to whole housing units, and as a result, the outcomes are potentially correlated within housing units. We consider intra-class (here, intra-cage) correlation in three published and two unpublished lifespan studies of aged mice encompassing more than 20,000 observations.

Introduction: Disorders of gut-brain interaction (DGBIs), like functional dyspepsia (FD), are prevalent and challenging conditions. In other gastrointestinal (GI) disorders, individuals from underserved areas (UAs) have difficulty accessing care. Little is known about UA FD patient perspectives of their care, especially in those with limited English proficiency (LEP).

We explored key risk factors for distress following the October 7, 2023, Hamas attacks on Israel, focusing on trauma exposure, gender, and event centrality.
Method: A longitudinal study design was used, assessing posttraumatic distress (PTSD), depression, generalized anxiety, event centrality, and functioning at approximately three (T1; n=858) and seven (T2, n=509) months post-attack.
