Multimorbidity latent classes in relation to 11-year mortality, risk factors and health-related quality of life in Malaysia: a prospective health and demographic surveillance system study.

Background: We aimed to identify specific multimorbidity latent classes among multi-ethnic community-dwelling adults aged ≥ 18 years in Malaysia. We further explored the risk factors associated with these patterns and examined the relationships between the multimorbidity patterns and 11-year all-cause mortality risk, as well as health-related quality of life (HRQoL).

Methods: Using data from 18,101 individuals (aged 18-97 years) from the baseline Census 2012, Health Round 2013, and Verbal Autopsies 2012-2023 of the South East Asia Community Observatory (SEACO) health and demographic surveillance system, latent class analysis was performed on 13 chronic health conditions to identify statistically and clinically meaningful groups.

Decoding KRAS mutation in non-small cell lung cancer patients receiving immunotherapy: A retrospective institutional comparison and literature review.

Introduction: KRAS mutation the most common molecular alteration in advanced non-small cell lung cancer (NSCLC) and is associated with an unfavourable prognosis, largely due to the lack of targeted therapeutic options for the majority of the KRAS mutated isoforms. The landscape of NSCLC treatment has expanded with the introduction of immune checkpoint inhibitors (ICIs). Nonetheless, data regarding the efficacy of ICI in NSCLC patients harbouring KRAS mutations are conflicting.

ClimateMind50+ a comprehensive short questionnaire to measure climate change knowledge, worries, preparedness, behaviours, and involvement of adults aged 50 and over.

The ClimateMind50+ questionnaire is a tailored instrument to assess the knowledge, concerns, preparedness, behaviours, and involvement of individuals aged 50 and above. Older adults are particularly vulnerable to climate-related hazards such as extreme heat, flooding, and severe storms, yet their perspectives and contributions to climate resilience remain underrepresented in research. The systematic development of the ClimateMind50+ involved rigorous cognitive testing with diverse participants, ensuring clarity, accessibility, and relevance.

Factors associated with attitudes toward death and dying in the second half of life: A scoping review.

How we think and feel about death and dying affects how we live our lives and our opportunities for healthy aging. This scoping review, using the PRISMA guidelines and drawing on the World Health Organizations public health framework for healthy aging, examined the personal, health and environmental factors associated with attitudes toward death and dying in persons 50 years and older. Most of the 74 eligible studies focused only on negative attitudes to death and few studies investigated the comprehensive range of factors that influence attitudes to death and dying.

Interventions for improving adherence to psychological treatments for common mental disorders: a systematic review.

Our systematic review aims to synthesise the evidence on interventions targeting improvement in patient adherence to psychological treatments for common mental disorders. A search was conducted on six electronic databases using search terms under the following concepts: common mental disorders, adherence, psychological treatments and controlled trial study design. Due to the heterogeneity in intervention content and outcomes evaluated in the included studies, a narrative synthesis was conducted.

A Polysocial Approach in Exploring Racial and Ethnic Differences in Dementia and Cognitive Decline Among U.S. Older Adults: Health and Retirement Study.

Background And Objectives: The racial or ethnic disparity in the burden of dementia exists among older adults in the United States, whereas gaps remain in understanding the synergic effect of multiple social determinants of health on diminishing this disparity. We aim to build a polysocial score for dementia and investigate the racial or ethnic difference in dementia risk among older persons with different polysocial score categories.

Research Design And Methods: In this prospective cohort study, we utilized longitudinal data from the Health and Retirement Study in the United States recruiting 6 945 participants aged ≥65 years who had data on 24 social determinants of health in 2006/2008.

Cross-Sectional and Prospective Associations between Parkinsonism and Parkinson's Disease with Frailty in Latin America.

Background: Little is known about the relationship between parkinsonism or Parkinson's disease (PD) and frailty in Latin America.

Objective: The study aimed to determine the cross-sectional and prospective associations between parkinsonism and PD with frailty in a large multi-country cohort in Latin America. Frailty was assessed using three different models to explore which definitions are more appropriate to screen for frailty in a PD population.

Neighbourhood environments and cognitive health in the longitudinal Personality and Total Health (PATH) through life study: A 12-year follow-up of older Australians.

Background: Urban neighbourhood environments may impact older adults' cognitive health. However, longitudinal studies examining key environmental correlates of cognitive health are lacking. We estimated cross-sectional and longitudinal associations of neighbourhood built and natural environments and ambient air pollution with multiple cognitive health outcomes in Australian urban dwellers aged 60+ years.

Systematic review on attitudes towards death and dying in adults 50 years and older living in countries with community transmission of COVID-19.

Background: The COVID-19 pandemic has underscored older adults' vulnerability to severe illness or death. Increased public awareness of mortality, with daily reminders of preventive measures, spurred interest in understanding the impact on death-related thoughts. This systematic review analyses existing literature on death attitudes among individuals aged 50 and older during the COVID-19 pandemic and focuses on associated factors.

Longitudinal associations of loneliness and social isolation with care dependence among older adults in Latin America and China: A 10/66 dementia research group population-based cohort study.

Objectives: With increasing life expectancy and rapid ageing, there is an expanding number of older people who have functional declines, greater needs for care and support and who are at increased risk of insufficient social interaction. Longitudinal investigations on the interplay between loneliness, social isolation and care dependence remain limited. This study thus aimed to investigate the longitudinal reciprocal association between social isolation/loneliness and care dependence among older adults in Latin America and China.

Pathogenic variants in autism gene cause hydrocephalus and disrupt neuronal connectivity by impairing ciliary microtubule dynamics.

Enlargement of the cerebrospinal fluid (CSF)-filled brain ventricles (cerebral ventriculomegaly), the cardinal feature of congenital hydrocephalus (CH), is increasingly recognized among patients with autism spectrum disorders (ASD). a member of Katanin family microtubule-severing ATPases, is a known ASD risk gene, but its roles in human brain development remain unclear. Here, we show that nonsense truncation of () in mice results in classic ciliopathy phenotypes, including impaired spermatogenesis and cerebral ventriculomegaly.

Persons With Cognitive Impairment and Care Partner Motivations and Experiences of Undergoing an Amyloid Scan: A Systematic Review of Qualitative Studies.

Background And Objectives: Amyloid positron emission tomography scans can enhance the accuracy of dementia diagnoses. However, the perspectives and experiences of people with cognitive impairment and their care partners undergoing an amyloid scan are less well understood. Therefore, this review aimed to identify and summarize qualitative studies exploring patient and care partner experiences of undergoing an amyloid scan.

Climate change and healthy ageing: An assessment of the impact of climate hazards on older people.

Background: Climate change not only directly impacts older people's longevity but also healthy ageing, which is the process of maintaining physical and mental capacities while optimising functional abilities. The urgency to address both population ageing and climate change necessitates a rethink and assessment of the impact of climate change on older people. This includes identifying what can be done to anticipate, mitigate and adapt to climate change and engage older persons.

The longitudinal associations between ambient air pollution exposure and dementia in the UK: results from the cognitive function and ageing study II and Wales.

Background: Air pollution has been recognised as a potential risk factor for dementia. Yet recent epidemiological research shows mixed evidence. The aim of this study is to investigate the longitudinal associations between ambient air pollution exposure and dementia in older people across five urban and rural areas in the UK.

Trends in outcomes used to measure the effectiveness of UK-based support interventions and services targeted at adults with experience of domestic and sexual violence and abuse: a scoping review.

Objectives: In the UK, a range of support services and interventions are available to people who have experienced or perpetrated domestic and sexual violence and abuse (DSVA). However, it is currently not clear which outcomes and outcome measures are used to assess their effectiveness. The objective of this review is to summarise, map and identify trends in outcome measures in evaluations of DSVA services and interventions in the UK.

A qualitative study of informal caregiver perceptions of the benefits of an early dementia diagnosis.

Background: Current and former dementia policies in the United Kingdom (UK) recommend diagnosing dementia early, or as close to the onset of symptoms as possible. Informal caregivers play an important role in initiating the diagnostic process and providing support to people living with dementia. Therefore, this study aimed to explore caregiver perceptions of the benefits of an early diagnosis.

Cost-effectiveness of early intervention in psychosis in low- and middle-income countries: economic evaluation from São Paulo, Brazil.

Aims: The effectiveness and cost-effectiveness of early intervention for psychosis (EIP) services are well established in high-income countries but not in low- and middle-income countries (LMICs). Despite the scarcity of local evidence, several EIP services have been implemented in LMICs. Local evaluations are warranted before adopting speciality models of care in LMICs.

Multistate survival modelling of multimorbidity and transitions across health needs states and death in an ageing population.

Background: Unmet health needs have the potential to capture health inequality. Nevertheless, the course of healthcare needs fulfilment, and the role of multimorbidity in this process remains unclear. This study assessed the bidirectional transitions between met and unmet health needs and the transition to death and examined the effect of multimorbidity on transitions.

Determinants of multimorbidity in low- and middle-income countries: A systematic review of longitudinal studies and discovery of evidence gaps.

Multimorbidity-the coexistence of at least two chronic health conditions within the same individual-is an important global health challenge. In high-income countries (HICs), multimorbidity is dominated by non-communicable diseases (NCDs); whereas, the situation may be different in low- and middle-income countries (LMICs), where chronic communicable diseases remain prominent. The aim of this systematic review was to identify determinants (including risk and protective factors) and potential mechanisms underlying multimorbidity from published longitudinal studies across diverse population-based or community-dwelling populations in LMICs.

Prevalence and Incidence of Parkinson's Disease in Latin America: A Meta-Analysis.

Background: Parkinson's disease (PD) is a rapidly growing neurodegenerative disorder, but up-to-date epidemiological data are lacking in Latin America. We sought to estimate the prevalence and incidence of PD and parkinsonism in Latin America.

Methods: We searched Medline, Embase, Scopus, Web of Science, Scientific Electronic Library Online, and Literatura Latino-Americana e do Caribe em Ciências da Saúde or the Latin American and Caribbean Health Science Literature databases for epidemiological studies reporting the prevalence or incidence of PD or parkinsonism in Latin America from their inception to 2022.

How effective are UK-based support interventions and services targeted at adults who have experienced domestic and sexual violence and abuse at improving their safety and wellbeing? A systematic review protocol.

Background: Domestic and sexual violence and abuse (DSVA) is prevalent in the UK, with wide-ranging impacts both on individuals and society. However, to date, there has been no systematic synthesis of the evidence for the effectiveness of UK-based support interventions and services for victim-survivors of DSVA. This review will aim to systematically collate, synthesise and quality assess the evidence regarding the effectiveness of UK support interventions and services targeted at those who have experienced DSVA.

Experiences of loneliness in lower- and middle-income countries: A systematic review of qualitative studies.

Loneliness is understood as a subjective experience resulting from unmet social relationship expectations. As most loneliness research has been conducted in higher-income-countries, there is limited understanding of loneliness in relation to diverse cultural, economic, and socio-political factors. To address this gap, the present review systematically synthesises existing qualitative studies on the experience of loneliness and social relationship expectations in lower- and middle-income countries (LMICs).

Burden of Parkinsonism and Parkinson's Disease on Health Service Use and Outcomes in Latin America.

Background: Little is known about the burden of parkinsonism and Parkinson's disease (PD) in Latin America. Better understanding of health service use and clinical outcomes in PD is needed to improve its prognosis.

Objective: The aim of the study was to estimate the burden of parkinsonism and PD in six Latin American countries.
