Bivalent Omicron BA.1 vaccine booster increases memory B cell breadth and neutralising antibodies against emerging SARS-CoV-2 variants.

Background: Current literature informs us that bivalent vaccines will generate a broader serum neutralizing antibody response to multiple SARS-CoV-2 variants, but studies on how this breadth relates to the memory B cell (MBC) and T cell responses are sparse. This study compared breadth of neutralising antibody, and memory B and T cell responses to monovalent or a bivalent ancestral/Omicron BA.1 COVID-19 booster vaccine.

Association of Weight Status and Waist Circumference with Physical Activity in people with Schizophrenia Spectrum Disorders and healthy controls.

Background: Individuals with Schizophrenia Spectrum Disorders (SSD) often suffer from obesity and do limited Physical Activity (PA). PA has many beneficial effects on a variety of somatic and mental variables and it should be strengthened among people with mental disorders. The relationship between Body Mass Index (BMI), Waist Circumference (WC), and PA in this population is poorly understood, with a lack of precise PA assessment.

Patient and healthcare practitioner evaluation of patient-reported outcomes in bariatric surgery - a modified Delphi study.

Background: Patient-reported outcomes are an important emerging metric increasingly utilised in clinical, research and registry settings. These outcomes, while vital, are underutilised and require refinement for the specific patient population of those undergoing bariatric surgery. This study aimed to investigate and compare how pre-surgical patients, post-surgical patients, and healthcare practitioners evaluate patient-reported outcomes of bariatric surgery to identify outcomes that are considered most important.

Young children's choices and thoughts about pro-social behaviour towards others with overweight.

Objectives: This study aimed to investigate weight bias within young children's pro-social choices between characters who differed in body size.

Methods: Seventy-six children aged 4-6 years read stories asking them to choose who they would first help, share with, comfort, and steal from, between a healthy weight and child with overweight. They also selected the one character they would most like to play with.

Mpox vaccination routes: prevalence, correlates and adverse effects of subcutaneous versus intradermal vaccination at a mass vaccination clinic in Sydney, Australia.

The Royal Prince Alfred Hospital Mpox Vaccination Clinic opened in response to the 2022 multicountry mpox outbreak. A total of 9500 vaccinations were administered intradermally and subcutaneously during the first 16 weeks of clinic operation. The rate of adverse events was 0.
