Lactobacillus rhamnosus modulates murine neonatal gut microbiota and inflammation caused by pathogenic Escherichia coli.

Background: Pathogenic Escherichia coli strains produce neonatal septicemia after colonizing the neonatal gut. While the probiotic Lactobacillus rhamnosus GG (LGG) effectively reduces neonatal sepsis, LGG's effects on the neonatal intestinal microbiota alterations and inflammation triggered by E. coli are incompletely understood.

Bidirectional changes in depressive symptoms and social functioning in older adults attending psychological therapy services.

Background: Impairments in the ability to carry out social activities commonly co-occur alongside depression. Improving social functioning is often overlooked in treatment. This is despite the high value placed by patients on social functioning and the potential for interventions focused on social functioning to have additional benefits in reducing depressive symptoms.

Cardiac autonomic function in REM-related obstructive sleep apnoea: insights from nocturnal heart rate variability profiles.

Purpose: In light of the reported association between REM-related obstructive sleep apnoea (OSA) and heightened cardiovascular risk, this study aims to compare cardiac autonomic function in patients with REM-OSA and OSA independent of sleep stage. We hypothesized that REM-OSA patients would exhibit higher sympathetic cardiac modulation based on heart rate variability (HRV) profiles.

Methods: HRV was compared between the OSA group (AHI ≥ 5 events/h, n = 252) and the REM-OSA group (AHI ≥ 5 events/h, AHIREM:AHINREM ≥ 2, n = 137).

Exploring deep caries management and barriers to the use of vital pulp treatments by primary care dental practitioners.

Aim: The European Society of Endodontology outlines best practices for the management of deep caries and the pulp. Despite evidence supporting vital pulp treatments (VPTs) as predictable alternatives to conventional endodontic treatment, studies have shown they are not widely adopted in the UK. This study aimed to explore the barriers to implementation of VPTs by primary care general dental practitioners (GDPs).

Characterisation of Symptom and Polysomnographic Profiles Associated with Cardiovascular Risk in a Sleep Clinic Population with Obstructive Sleep Apnoea.

Aim: Recent data have identified specific symptom and polysomnographic profiles associated with cardiovascular disease (CVD) in patients with obstructive sleep apnoea (OSA). Our aim was to determine whether these profiles were present at diagnosis of OSA in patients with established CVD and in those with high cardiovascular risk. Participants in the Sydney Sleep Biobank (SSB) database, aged 30-74 years, self-reported presence of CVD (coronary artery disease, cerebrovascular disease, or heart failure).
