Protocol for a mixed-methods randomised controlled trial evaluating the psychosocial effects of an expressive arts-based intervention on adults with age-related macular degeneration.

Introduction: Age-related macular degeneration (AMD) is a prevalent eye disease among middle-aged and older adults. AMD leaves the patient with irreversible deteriorating vision, which profoundly impacts their daily lives and psychosocial well-being. Given the limited studies addressing the psychosocial needs of adults with AMD and, in particular, using an expressive arts-based intervention (EXABI) as an intervention, this study aims to investigate the effectiveness of such an intervention in enhancing the psychosocial well-being of adults with AMD.

Comorbid anxiety, loneliness, and chronic pain as predictors of intervention outcomes for subclinical depressive symptoms in older adults: evidence from a large community-based study in Hong Kong.

Background: Depression is among the leading causes of the global burden of disease and is associated with substantial morbidity in old age. The importance of providing timely intervention, particularly those with subclinical symptoms, has thus increasingly been emphasised. Despite their overall effectiveness, a small but notable subgroup tends to be less responsive to interventions.

Effect of a single-session mindfulness-based intervention for reducing stress in family caregivers of people with dementia: study protocol for a randomized controlled trial.

Background: Caregiver stress can pose serious health and psychological concerns, highlighting the importance of timely interventions for family caregivers of people with dementia. Single-session mindfulness-based interventions could be a promising yet under-researched approach to enhancing their mental well-being within their unpredictable, time-constrained contexts. This trial will evaluate the effectiveness and feasibility of a blended mindfulness-based intervention consisting of a single session and app-based follow-up in reducing caregiver stress.

Enhanced Cognition and Modulation of Brain Connectivity in Mild Neurocognitive Disorder: The Promise of Transcranial Pulse Stimulation.

Existing pharmacological treatments for mild neurocognitive disorder (NCD) offer limited effectiveness and adverse side effects. Transcranial pulse stimulation (TPS) utilizing ultrashort ultrasound pulses reaches deep brain regions and may circumvent conductivity issues associated with brain stimulation. This study addresses the gap in TPS research for mild NCD during a critical intervention period before irreversible cognitive degradation.

Environmental stress and emotional reactivity: an exploratory experience sampling method study.

Background: Previous studies have shown a relationship between environments and mental health. However, limited studies have investigated the impact of environment stress (ES) on emotional reactivity. Our study aimed to fill this gap by examining how daily ES affects momentary emotional reactivity using experience sampling method (ESM).

This observational cross-sectional study aimed to comprehensively examine prevalence and correlates of psychological distress, in terms of depression, anxiety and post-traumatic-stress-disorder (PTSD)-like symptoms, among Chinese adult psychiatric outpatients amidst the peak of fifth COVID-19 wave in Hong-Kong.

Methods: A total of 415 patients (comprising 246 patients with common-mental-disorders [CMD] and 169 with severe-mental-disorders [SMD]) and 399 demographically-matched controls without mental disorders were assessed with self-rated questionnaires between 28-March and 8-April-2022, encompassing illness profile, mental health symptoms, psychosocial measures (loneliness, resilience, coping styles) and COVID-19 related factors.

The modulation effect of cognition on mentalization in late-life depression: a study of gaze perception-a potential screening tool for high-risk group of late-life depression.

Introduction: Impairment in mentalization is implicated in the development and maintenance of depression. Major depressive disorders showed significant impairment in social cognition and such impairment appears to be positively associated with the severity of depression. Self-referential gaze perception (SRGP), a measurement of mentalization, was predominantly measured in patients with psychosis but rarely examined in late-life depression (LLD).

Antimicrobial resistance and population genomics of emerging multidrug-resistant 4,[5],12:i:- in Guangdong, China.

4,[5],12:i:-, a monophasic variant of Typhimurium, has emerged as a global cause of multidrug-resistant salmonellosis and has become endemic in many developing and developed countries, especially in China. Here, we have sequenced 352 clinical isolates in Guangdong, China, during 2009-2019 and performed a large-scale collection of 4,[5],12:i:- with whole genome sequencing (WGS) data across the globe, to better understand the population structure, antimicrobial resistance (AMR) genomic characterization, and transmission routes of 4,[5],12:i:- across Guangdong. 4,[5],12:i:- strains showed broad genetic diversity; Guangdong isolates were found to be widely distributed among the global lineages.

Maintenance and generation of proton motive force are both essential for expression of phenotypic antibiotic tolerance in bacteria.

Bacterial antibiotic tolerance, a phenomenon first observed in 1944, is known to be responsible for both onset and exacerbation of recurrent and chronic bacterial infections. The development of antibiotic tolerance was previously thought to be due to a switch to physiological dormancy when bacteria encounter adverse growth conditions. Our recent laboratory findings, however, showed that a set of genes related to the maintenance of proton motive force (PMF) are up-regulated under starvation, indicating that the tolerant sub-population, which are commonly known as persisters, can actively maintain their tolerance phenotypes.

Prevalence and molecular characterization of cefotaxime-resistant strains recovered from retail meat samples in Shenzhen, China, during 2014-2017.

In this work, we collected foodborne strains in Shenzhen, China, during 2014-2017 and investigated the genetic profile of all cefotaxime-resistant isolates in the collection. The strains were subjected to antimicrobial susceptibility tests, whole-genome sequencing, bioinformatics analysis, and conjugation studies. A total of 79 cefotaxime-resistant were identified and found to exhibit multidrug resistance.

Transcranial pulse stimulation in the treatment of mild neurocognitive disorders.

Objective: There are limited effectiveness and potential side effects of existing pharmacological approach in treating mild neurocognitive disorder (NCD). Transcranial pulse stimulation (TPS) applies repetitive single high-pressure ultrashort shockwave pulses to stimulate the brain, which has been shown to effectively improve cognition in major NCD. However, the effectiveness of TPS in mild NCD patients remained unknown.

Using the health belief model to understand the factors influencing the perceptions of people of Chinese ancestry about reducing salt consumption for hypertension prevention: A cross-sectional study.

Background: High-salt diets are linked to hypertension. Chinese people in Australia, are at increased risk of hypertension due to the combination of routine addition of high quantities of salt to food during cooking and high salt levels in processed western foods. There is a scarcity of salt-related behavioural studies on this population group.

COVID-19 perseverative cognition and depressive symptoms in Hong Kong: The moderating role of resilience, loneliness and coping strategies.

Background: The COVID-19 pandemic significantly increased depression prevalence in general population. However, the relationship between persistent dysfunctional thinking associated with COVID-19 (perseverative-cognition) and depression, and its potential moderators are understudied. We aimed to examine the association between COVID-19 perseverative-cognition and depression, and the moderating effect of potential risk and protective factors on this association in general public during the peak of fifth COVID-19 wave in Hong Kong.
