A qualitative study on general practitioners’ perspectives on late-life depression in Singapore – Part I: patient presentations and behaviours

Background Detection and management of late-life depression largely relies on primary care. Yet in Singapore, older adults are unlikely to seek help for their mental health from their primary care providers. This qualitative study explores how late-life depression manifests to general practitioners (GPs) in the Singaporean primary care setting. Methods Twenty-eight private GPs practicing in Singapore were asked about their clinical experience with late-life depression during semi-structured group and individual discussions conducted online. Participants were purposively sampled across age, gender, and ethnicity (Chinese, Malay, Indian). Transcripts were analysed with reflexive thematic analysis. Findings To GPs, depression in older patients often manifests through somatic symptoms or subtle behavioural changes, only detectable through follow-ups or collateral history. GPs reported that older patients attribute depressive symptoms to normal ageing or do not mention them, particularly within an Asian culture further encouraging stoic endurance. GPs perceived late-life depression as reactions to ageing-related stressors, with male, low-income, or institutionalised patients being at particular risk of insidious, severe depression. GPs noted ethnic differences regarding families’ involvement in care, which they described as helpful, but sometimes stress-provoking for patients. Fear of burdensomeness or loss of autonomy/social role could prompt rejection of diagnosis and treatment in patients. GPs considered good patient-doctor rapport as a facilitator at every step of the care process, noting more favourable prognosis in care-concordant patients. Interpretation Depression in older adults in Singapore can be covert, with successful management relying on GPs’ ability to pick up on subtle changes, assess patients holistically, and build rapport with patients and families

Knowledge, attitude, and practice toward herpes zoster (HZ) and HZ vaccination: Concept elicitation findings from a multi-country study in the Asia Pacific

ABSTRACTHerpes zoster (HZ) is a prevalent disease characterized by a painful rash. A multi‑country study was conducted to elicit public and physician knowledge, attitude, and practice (KAP) toward HZ disease and vaccination for the assessment of local factors influencing HZ vaccine perceptions in four Asian-Pacific countries/territories One-to-one qualitative interviews were conducted in 2022, among the public (people aged ≥ 50 years, adults with parents aged ≥ 50 years, zoster vaccine live-vaccinated individuals aged ≥ 50 years in Republic of Korea, and HZ patients; n = 78) and physicians (general practitioners and specialists; n = 24). Themes surrounding KAP toward HZ and HZ vaccination were summarized using a thematic analysis. A substantial knowledge gap related to HZ was observed among the public, including its causes, long-term impacts, and the at-risk population. There was a low perceived risk of HZ and low general awareness of HZ vaccine availability, although country/territory-specific differences existed. Fear of HZ-associated pain contributed toward vaccination intent among HZ patients and adults with parents aged ≥ 50 years. HZ-naïve adults who were encouraged to receive the vaccine by others were not motivated to do so due to optimism bias. Physicians were perceived to be a reliable source of information. However, physicians did not always proactively discuss HZ vaccination due to time constraints and a perceived need to prioritize other vaccinations including influenza and pneumococcal vaccines. Initiatives are needed to improve public awareness of HZ and its complications, in terms of overall impact on individuals and society, and highlight the important role of physicians in recommending vaccination

The genome of Shorea leprosula (Dipterocarpaceae) highlights the ecological relevance of drought in aseasonal tropical rainforests

Hyperdiverse tropical rainforests, such as the aseasonal forests in Southeast Asia, are supported by high annual rainfall. Its canopy is dominated by the species-rich tree family of Dipterocarpaceae (Asian dipterocarps), which has both ecological (e.g., supports flora and fauna) and economical (e.g., timber production) importance. Recent ecological studies suggested that rare irregular drought events may be an environmental stress and signal for the tropical trees. We assembled the genome of a widespread but near threatened dipterocarp, Shorea leprosula, and analyzed the transcriptome sequences of ten dipterocarp species representing seven genera. Comparative genomic and molecular dating analyses suggested a whole-genome duplication close to the Cretaceous-Paleogene extinction event followed by the diversification of major dipterocarp lineages (i.e. Dipterocarpoideae). Interestingly, the retained duplicated genes were enriched for genes upregulated by no-irrigation treatment. These findings provide molecular support for the relevance of drought for tropical trees despite the lack of an annual dry season
