New guidelines for the effectiveness of exercise in the prevention of dementia: Implications for psychiatry.

To the Editors, We recently published evidence-based guidelines for the role of exercise in the prevention of dementia.1 The guidelines combined an umbrella review and expert consensus, and has important implications for psychiatry. Evidence from published studies was evaluated using the GRADE assessment. We found scarce and relatively low-quality evidence in the literature, particularly for the primary prevention of dementia. Our GRADE-informed evidence synthesis yielded the following conclusions: For Primary prevention of dementia: Physical activity may be considered for the primary prevention of dementia. In people without dementia or MCI, exercise may be no better than health education for the primary prevention of dementia and MCI. QUALITY OF EVIDENCE: Very low for physical activity; very low for exercise. For Secondary prevention of dementia: In people with MCI there is continued uncertainty about the role of physical activity and exercise in slowing the conversion to dementia. QUALITY OF EVIDENCE: Very low for physical activity; very low for exercise. For Tertiary prevention of dementia: In people with moderate dementia, physical activity/exercise could be considered for maintaining cognition and exercise could be considered for stabilizing disability compared to usual care. QUALITY OF EVIDENCE: Exercise: very low for cognitive outcomes; low for disability. Following a consensus process, we recommended physical activity/exercise for all three purposes, namely primary, secondary, and tertiary prevention (improve cognition and reduce disability) of dementia. The recommendation of exercise was largely contingent on its positive effects on mental health,2,3 in conjunction with the extensive body of evidence linking mental disorder with dementia.4 The guidelines highlight the need for further research on multidisciplinary interventions for both the primary and secondary prevention of dementia. A question remains whether the positive effect of physical activity on mood/behaviour applies to the MCI group, as it does to the dementia group. More research is required in people with established dementia and in less common forms of dementia. The guidelines also make an implicit research recommendation in support of heurism, in the sense that they integrate the evidence-based expectation that exercise is likely to be beneficial both for mental and physical health. Indeed, employing heurism may be inherently necessary in prevention research.5 Overall, these guidelines offer an evidence-based insight into the effectiveness of physical activity/exercise for the prevention (primary, secondary, and tertiary) of dementia. Importantly, they necessitate the inclusion of mental health in a multi-component approach. In doing so, they emphasize the necessity of mental health promotion and mental illness prevention in the prevention and management of dementia.

Alert for the high prevalence of vitamin D deficiency in adolescents in a large Brazilian sample

Abstract Objective: To estimate the prevalence of vitamin D deficiency and severe deficiency in children and adolescents, in a large Brazilian sample. Methodology: Results of 413,988 25(OH)D measurements in children and adolescents aged 0 to 18 years collected between 01/2014 and 10/2018 were obtained from the database of a Clinical Laboratory. In this population, 25 hydroxyvitamin D concentrations below 20 ng/mL are considered deficient, and below 12 ng/mL as severe deficiency. All measurements were performed by immunoassay and the results were distributed by gender, age group, seasonality, and latitude. Results: The mean of 25(OH)D levels was 29.2 ng/mL with a standard deviation of 9.2 ng/mL. Of the total samples, 0.8% had a concentration < 12 ng/mL, and 12.5% of the samples had a concentration < 20 ng/mL, with a higher prevalence in females. Children under 2 years of age had the lowest prevalence. The effects of latitude and seasonality were quite evident. In samples of female adolescents from the southern region in winter, 36% of vitamin D deficiency and 5% of severe deficiency were found. Conclusion: In this large number of measurements of 25(OH)D in children and adolescents, 12.5% had a deficiency and 0.8% had severe deficiency. A greater deficiency was observed among adolescents, especially females, which raises questions about the need for supplementation during this period of life.

Dying well in Aotearoa New Zealand for ethnic minority communities: a time for reclamation?

Despite technological advances and a disproportionate increase in health expenditure at the end-of-life, most New Zealanders die in hospital or in aged residential care. This counters the aspirations espoused by Te Whatu Ora (Health New Zealand) for all New Zealanders "to live well, age well and die well in their homes and communities." Furthermore, despite reported inequities in end-of-life care experienced by ethnic minority communities (EMCs) overseas, and increasing proportions of people identifying with Asian, Middle Eastern, Latin American and African ethnicities in Aotearoa New Zealand, local data, research and policies addressing healthcare needs of EMCs at end-of-life are scant. Acknowledging this invisibility, we reflect on and discuss the current discourses on death and dying, the complex experiences at end-of-life for EMCs, including concepts of a "good death", the impact of recent existential crises (e.g., COVID-19 pandemic, climate change) on death awareness, and the global rise to reclaim dying as an important part of living. We argue for the need: a) to partner with ethnic communities to co-design culturally safe end-of-life health services, and b) to adopt a "compassionate communities" public health approach that can support people of EMCs at the end-of-life to die well.

Child sexual abuse, mental health, and legislation in India and Thailand: A cross-country comparison.

INTRODUCTION: Child sexual abuse (CSA) is a serious public health issue in India and Thailand. To identify potential barriers for addressing CSA in these countries, it is necessary to explore and compare research, laws, and policies in these two countries. MATERIAL AND METHODS: The Scopus and PubMed databases were searched for published literature on "Child Sexual Abuse" AND "India" OR "Thailand" concerning research focus, prevalence, factors, and policies or interventions on CSA. Main legislations related to CSA were compared using a predefined outline. Additionally, authors compared and analysed current legislation in relation to the United Nations Convention on the Rights of the Child (UNCRC). RESULTS: Published literature (n = 64) included original articles (n = 26), reviews (n = 36), editorials or letters to the editor (n = 2). No collaboration on CSA between the two countries was found. Several differences in the main legislation (e.g., punishment, services) of India and Thailand were observed, both between countries and in relation to the UNCRC. CONCLUSION: Our findings suggest that CSA is mostly under-researched in both countries in terms of services, policy and legislation. There is a need for cross-country, multidisciplinary, and collaborative research on CSA in both India and Thailand.

Mental health research in South America: Psychiatrists and psychiatry trainees' perceived resources and barriers.

As mental health issues continue to rise in Latin America, the need for research in this field becomes increasingly pressing. This study aimed to explore the perceived barriers and resources for research and publications among psychiatrists and psychiatry trainees from nine Spanish-speaking countries in South America. Data was collected through an anonymous online survey and analyzed using descriptive methods and the SPSS Statistical package. In total, 214 responses were analyzed. Among the participating psychiatrists, 61.8% reported having led a research project and 74.7% of them reported having led an academic publication. As for the psychiatry trainees, 26% reported having conducted research and 41.5% reported having published or attempted to publish an academic paper. When available, having access to research training, protected research time and mentorship opportunities were significant resources for research. Further support is needed in terms of funding, training, protected research time and mentorship opportunities. However, despite their efforts to participate in the global mental health discussion, Latin American psychiatrists and psychiatry trainees remain largely underrepresented in the literature.

Physical activity and exercise for the prevention and management of mild cognitive impairment and dementia: a collaborative international guideline.

BACKGROUND: Physical activity and exercise have been suggested as effective interventions for the prevention and management of mild cognitive impairment (MCI) and dementia, but there are no international guidelines. OBJECTIVES: To create a set of evidence- and expert consensus-based prevention and management recommendations regarding physical activity (any bodily movement produced by skeletal muscles that results in energy expenditure) and exercise (a subset of physical activity that is planned, structured, repetitive), applicable to a range of individuals from healthy older adults to those with MCI/dementia. METHODS: Guideline content was developed with input from several scientific and lay representatives' societies. A systematic search across multidisciplinary databases was carried out until October 2021. Recommendations for prevention and management were developed according to the GRADE and complemented by consensus statements from the expert panels. RECOMMENDATIONS: Physical activity may be considered for the primary prevention of dementia. In people with MCI there is continued uncertainty about the role of physical activity in slowing the conversion to dementia. Mind-body interventions have the greatest supporting evidence. In people with moderate dementia, exercise may be used for maintaining disability and cognition. All these recommendations were based on a very low/low certainty of evidence. CONCLUSIONS: Although the scientific evidence on the beneficial role of physical activity and exercise in preserving cognitive functions in subjects with normal cognition, MCI or dementia is inconclusive, this panel, composed of scientific societies and other stakeholders, recommends their implementation based on their beneficial effects on almost all facets of health.

An intersectional approach to exploring lived realities and harnessing the creativity of ethnic minority youth for health gains: protocol for a multiphase mixed method study.

BACKGROUND: Understanding the diversity and multiplicity of identities experienced by youth in Aotearoa (Te reo Maori name of the country) New Zealand (NZ) is vital to promoting their wellbeing. Ethnic minority youth (EMY) in NZ (defined as those identifying with Asian, Middle Eastern, Latin American and African ethnic origins) have been historically under-studied and under-counted, despite reporting high levels of discrimination, a major determinant of mental health and wellbeing and potentially a proxy for other inequities. In this paper, we describe the protocol for a multi-year study that examines, using an intersectional approach, how multiple marginalised identities impact mental and emotional wellbeing of EMY. METHODS: This is a multiphase, multi-method study designed to capture the diversity of lived realities of EMY who self-identify with one or more additional marginalised intersecting identity (the population referred here as EMYi). Phase 1 (Descriptive study) will involve secondary analyses of national surveys to examine the prevalence and relationships between discrimination and wellbeing of EMYi. Phase 2 (Study on public discourse) will analyse data from media narratives, complemented by interviews with stakeholders to explore discourses around EMYi. Phase 3 (Study on lived experience) will examine lived experiences of EMYi to discuss challenges and sources of resilience, and how these are influenced by public discourse. Phase 4 (Co-design phase) will use a creative approach that is youth-centered and participatory, and will involve EMYi, creative mentors and health service, policy and community stakeholders as research partners and advisors. It will employ participatory generative creative methods to explore strengths-based solutions to discriminatory experiences. DISCUSSION: This study will explore the implications of public discourse, racism and multiple forms of marginalisation on the wellbeing of EMYi. It is expected to provide evidence on the impacts of marginalisation on their mental and emotional wellbeing and inform responsive health practice and policy. Using established research tools and innovative creative means, it will enable EMYi to propose their own strength-based solutions. Further, population-based empirical research on intersectionality and health is still nascent, and even more scarce in relation to youth. This study will present the possibility of expanding its applicability in public health research focused on under-served communities.

Impact of an Electronic Alert in Combination with a Care Bundle on the Outcomes of Acute Kidney Injury.

Early diagnosis is essential for the appropriate management of acute kidney injury (AKI). We evaluated the impact of an electronic AKI alert together with a care bundle on the progression and mortality of AKI. This was a single-center prospective study that included AKI patients aged ≥ 18 years, whereas those in palliative care, nephrology, and transplantation departments were excluded. An AKI alert was issued in electronic medical records and a care bundle was suggested. A series of classes were administered to the multidisciplinary teams by nephrologists, and a clinical pharmacist audited prescriptions. Patients were categorized into pre-alert and post-alert groups. The baseline characteristics were comparable between the pre-alert (n = 1613) and post-alert (n = 1561) groups. The 30-day mortality rate was 33.6% in the entire cohort and was lower in the post-alert group (30.5% vs. 36.7%; p < 0.001). Age, pulmonary disease, malignancy, and ICU admission were associated with an increase in 30-day mortality. The electronic AKI alert together with a care bundle and a multidisciplinary education program was associated with a reduction in 30-day mortality in patients with AKI.
