Photoacoustic and fluorescence dual-modality imaging of cerebral biomarkers in Alzheimer's disease rodent model.

Significance: Alzheimer's disease (AD) is a predominant form of dementia that can lead to a decline in the quality of life and mortality. The understanding of the pathological changes requires monitoring of multiple cerebral biomarkers simultaneously with high resolution. Photoacoustic microscopy resolves single capillaries, allowing investigations into the most affected types of vessels.

Rates of colorectal cancer diagnosis and mortality in people with severe mental illness: results from Australia's National Bowel Cancer Screening Programme.

Aims: Studies show that people with severe mental illness (SMI) have a greater risk of dying from colorectal cancer (CRC). These studies mostly predate the introduction of national bowel cancer screening programmes (NBCSPs) and it is unknown if these have reduced disparity in CRC-related mortality for people with SMI.

Methods: We compared mortality rates following CRC diagnosis at colonoscopy between a nationally representative sample of people with and without SMI who participated in Australia's NBCSP.

Chronic pain and complex regional pain syndrome are associated with alterations to the intestinal microbiota in both humans and mice. An observational cross-sectional study.

Objective: This study aimed to evaluate pain metrics and gut microbiota differences from human subjects with complex regional pain syndrome (CRPS) compared to cohabitants (HHC) and non-cohabitating (biobank) controls. In addition, we aimed evaluate longitudinal changes of gut microbiota using a mouse model of acute and chronic CRPS.

Methods: In an observational, cross-sectional study, 25 patients with CRPS and 24 household controls (HHC) were recruited, completed pain questionnaires, and submitted stool samples.

Effects of Varenicline, Bupropion, Nicotine Patch, and Placebo on Treating Smoking Among Persons With Current or Past Major Depressive Disorder: Secondary Analysis of a Double-Blind, Randomized, Placebo-Controlled Trial.

Objective: The aim of this study was to compare the safety and efficacy of the leading smoking cessation medications among individuals with current versus past major depressive disorder (MDD).

Methods: This was a secondary analysis of a randomized, double-blind trial over 12 weeks with varenicline or bupropion, followed by a 12-week assessment, in participants ages 18-75 with past (N=2,174) or current (N=451) MDD or without psychiatric disorders (N=4,028). Interventions included 12 weeks of pharmacotherapy with placebo, nicotine replacement therapy (NRT; nicotine patch), bupropion, or varenicline, and brief counseling.

Disclosure and non-disclosure of childhood sexual abuse in Australia: Results from a national survey.

Background: Little population-based evidence exists about prevalence of lifetime disclosure and non-disclosure of child sexual abuse (CSA). Evidence is lacking about disclosure by girls and women compared with boys and men, and gender diverse individuals. It is unclear if disclosure is more common in contemporary society, and if disclosure is influenced by abuse severity and perpetrator type.
