Prevalence of vitamin D insufficiency in early pregnancies- a Singapore study.

Vitamin D plays an essential role in bone and mineral metabolism. There is increased interest in understanding prevalence of Vitamin D deficiency in pregnancy as many studies report association of low vitamin D levels with obstetric complications and neonatal sequelae. There is a paucity of studies in Singapore evaluating levels of vitamin D levels during the first trimester of pregnancies. We aim to study the prevalence of vitamin D insufficiency in this population. Our study assessed vitamin D levels in these women. Vitamin D (Plasma 25(OH)D concentration) levels in multiracial women during the first trimester were collected via venepuncture at their booking antenatal visit. They were stratified into sufficient ≥30ng/ml, insufficient ≥20ng/ml and <30ng/ml, moderately deficient ≥10ng/ml and <20ng/ml and severely deficient <10ng/ml. 93 women were included in this study. Only 2.2% of our study population had sufficient vitamin D levels. In women who had insufficient levels, the heavier the weight, the more likely to be vitamin D deficient. Interestingly, we also note that the older the patient, the less likely they are to be deficient. In women with periconceptual multivitamin supplementation, the average vitamin D level for those with supplementation was 2.10ng/ml higher than those without. Majority of patients were recruited from a single study member's patient pool who were mostly Chinese. Prevalence of Vitamin D deficiency in general obstetric patients with higher BMI and darker skinned patients may be even lower in Singapore. The high prevalence of Vitamin D insufficiency in our patients prove that it is a prominent problem in our population. We aim to implement screening of vitamin D levels as part of antenatal investigations in the first trimester and recommend supplementation as required. We also hope to evaluate the association of low vitamin D levels with obstetric or neonatal complications further understanding its implications.

Predictors of post stroke cognitive impairment: VITATOPS cognition substudy.

INTRODUCTION: Post stroke cognitive impairment (PSCI) is a common complication of ischemic stroke. PSCI can involve different depending on clinical and stroke related characteristics. The aim of this study is to determine the factors associated with impairments in specific cognitive domains. METHODS: The Vitamins to Prevent Stroke (VITATOPS) trial is a large, multinational randomised controlled trial. In this substudy, consecutive patients admitted for ischaemic stroke or transient ischaemic attack (TIA) at a tertiary hospital in Singapore were included. PSCI was defined as impairment of any of the six cognitive subgroups - visuoconstruction, attention, verbal memory, language, visual memory and visuomotor function - that were assessed annually for up to five years. Univariate and multivariate Cox proportional hazard models were used to determine factors associated with impairments in each of these cognitive domains. RESULTS: A total of 736 patients were included in this study, of which 173 (23.5 %) developed cognitive impairment. Out of the six cognitive domains, the greatest proportion of patients had an impairment in visuoconstruction (26.4 %) followed by attention (19.8 %), verbal memory (18.3 %), language (17.5 %), visual memory (17.3 %) and visuomotor function (14.8 %). Patients with posterior circulation cerebral infarction (POCI) as the index stroke subtype had higher rates of cognitive impairment. Further subgroup analyses show that Indian race and advanced age were predictive of language impairment, whilst fewer years of education and POCI were predictive of verbal memory impairment. POCI was predictive of visual memory impairment, and advanced age and POCI were predictive of visuomotor function impairment. CONCLUSION: We identified visuoconstruction and attention domains to be the most affected in our Asian cohort of PSCI. Advanced age, lower levels of education, posterior circulation strokes and concomitant comorbidities such as peripheral artery disease are independent predictors of PSCI.

Navigating drug use, cessation, and recovery: a retrospective case notes review among sexual minority men at a community-based service in Singapore.

BACKGROUND: In Singapore, where drug use is a highly stigmatized and criminalized issue, there is limited understanding of the challenges faced by individuals, particularly sexual minority men, in their journey towards recovery from substance dependence or addiction. This qualitative study aimed to investigate the driving forces behind drug use, the factors contributing to drug cessation, and the elements influencing the recovery process. METHODS: Data were extracted from clinical records provided by  The Greenhouse Community Services Limited between January 2020 to May 2022. These records encompassed information from four distinct forms: the intake assessment, progress notes, case closing summary, and the care plan review. Thematic analysis was employed to identify and categorize recurring themes within the data. RESULTS: Data from beneficiaries (n = 125) were analyzed and yielded a series of themes related to facilitators of drug use, motivations to cease drug use, and managing one's ongoing recovery. Within the facilitators of drug use, two sub-themes were identified: (a) addressing trauma and triggers and (b) managing emotions. Additionally, managing one's recovery was marked by four significant sub-themes: (a) uncovering personal identities, (b) losing motivation and drive, (c) overcoming obstacles, and (d) preparing for aftercare. CONCLUSIONS: The study contributes valuable insights into the dynamics of ongoing recovery management, offering potential avenues for interventions that could enhance support for individuals in their journey to overcome substance dependence. Enhancing psychoeducation and fostering peer support have the potential to facilitate the recovery process. Clearly, a holistic approach is needed to address these complex issues that cuts across our societies.

Cost-effectiveness analysis of add-on pertuzumab to trastuzumab biosimilar and chemotherapy as neoadjuvant treatment for human epidermal growth receptor 2-positive early breast cancer patients in Singapore.

OBJECTIVES: The Asian PEONY trial showed that add-on pertuzumab to trastuzumab and chemotherapy significantly improved pathological complete response in the neoadjuvant treatment of patients with human epidermal growth factor receptor 2-positive (HER2+) early breast cancer (EBC). This study evaluated the cost-effectiveness of pertuzumab as an add-on therapy to trastuzumab and chemotherapy for neoadjuvant treatment of patients with HER2+ EBC in Singapore. METHODS: A six-state Markov model was developed from the Singapore healthcare system perspective, with a lifetime time horizon. Model outputs were: costs; life-years (LYs); quality-adjusted LYs (QALYs); incremental cost-effectiveness ratios (ICERs). Sensitivity/scenario analyses explored model uncertainties. RESULTS: The base case projected the addition of pertuzumab to be associated with improved outcomes by 0.277 LYs and 0.271 QALYs, increased costs by S$1,387, and an ICER of S$5,121/QALY. The ICER was most sensitive to the pCR rate, and the probabilistic sensitivity analysis showed that add-on pertuzumab had an 81.3% probability of being cost-effective at a willingness-to-pay threshold of S$45,000/QALY gained. CONCLUSIONS: This model demonstrated that the long-term clinical impact of early pertuzumab use, particularly the avoidance of metastatic disease and thus avoidance of higher costs and mortality rates, make neoadjuvant pertuzumab a cost-effective option in the management of patients with HER2+ breast cancer in Singapore.

Effectiveness of mindfulness-based interventions delivered via technology versus therapist among patients on peritoneal dialysis at an outpatient clinic in Singapore.

AIMS: This study aimed to (i) evaluate the effectiveness of mindfulness-based interventions in improving self-efficacy, reducing stress and anxiety among peritoneal dialysis patients, and (ii) compare the most effective method of mindfulness based interventions. METHODS: This randomized three-arm controlled trial recruited first-time peritoneal dialysis patients from the peritoneal dialysis outpatient clinic in Singapore. Patients were randomly allocated to either video-assisted mindfulness training, therapist-assisted mindfulness training or treatment-as-usual. All groups received 4.5 days of structured peritoneal dialysis training at the peritoneal dialysis centre, while video-assisted mindfulness training and therapist-assisted mindfulness training groups were taught additional mindfulness-based techniques. The perceived stress scale, self-efficacy, and anxiety (State and Trait Anxiety Inventory) were measured at baseline, 4- and 12 weeks post-randomization, using reliable and valid instruments. RESULTS: Thirty-nine patients were recruited (13 in each group). All the therapies showed a significant time trend in anxiety. Only therapist- and video-assisted mindfulness training showed a significant trend in perceived stress scale scores but not treatment-as-usual. All Intervention X Time interactions were not significant. Patients in therapist- and video-assisted mindfulness training groups had reduced perceived stress scale scores compared to treatment-as-usual at week 12. CONCLUSION: This study demonstrated the potential of mindfulness-based interventions in reducing stress among first-time PD patients.

Cost-effectiveness of alternative first- and second-line treatments for benign prostatic hyperplasia in Singapore.

BACKGROUND: Minimally invasive surgical therapies, such as water vapor thermal therapy (WVTT) and prostatic urethral lift (PUL), are typically second-line options for patients in whom medical management (MM) failed but who are unwilling or unsuitable to undergo invasive transurethral resection of the prostate (TURP). However, the incremental cost-effectiveness of WVTT or PUL as first- or second-line therapy is unknown. We evaluated the incremental cost-effectiveness of alternative first- and second-line treatments for patients with moderate-to-severe benign prostatic hyperplasia (BPH) in Singapore to help policymakers make subsidy decisions based on value for money. METHODS: We considered six stepped-up treatment strategies, beginning with MM, WVTT, PUL or TURP. In each strategy, patients requiring retreatment advance to a more invasive treatment until TURP, which may be undergone twice. A Markov cohort model was used to simulate transitions between BPH severity states and retreatment, accruing costs and quality-adjusted life-years (QALYs) over a lifetime horizon. RESULTS: In moderate patients, strategies beginning with MM had similar cost and effectiveness, and first-line WVTT was incrementally cost-effective to first-line MM (33,307 SGD/QALY). First-line TURP was not incrementally cost-effective to first-line WVTT (159,361 SGD/QALY). For severe patients, WVTT was incrementally cost-effective to MM as a first-line treatment (30,133 SGD/QALY) and to TURP as a second-line treatment following MM (6877 SGD/QALY). TURP was incrementally cost-effective to WVTT as a first-line treatment (48,209 SGD/QALY) in severe patients only. All pathways involving PUL were dominated (higher costs and lower QALYs). CONCLUSION: Based on the common willingness-to-pay threshold of SGD 50,000/QALY, this study demonstrates the cost-effectiveness of WVTT over MM as first-line treatment for patients with moderate or severe BPH, suggesting it represents good value for money and should be considered for subsidy. PUL is not cost-effective as a first- nor second-line treatment. For patients with severe BPH, TURP as first-line is also cost-effective.

Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate, common among older men. Its symptoms include difficulties with starting and completing urination, incontinence, frequent and urgent need to urinate. Minimally invasive procedures, such as water vapor thermal therapy (WVTT) and prostatic urethral lift (PUL), are typically offered as second-line options to patients for whom medication has failed but who are unwilling or unsuitable to undergo invasive surgery (transurethral resection of the prostate, TURP). However, whether offering these procedures as first-line options represents good value for money (i.e. cost-effectiveness) is an open question. To address this question and inform subsidy decisions in Singapore, we investigated six stepped-up treatment strategies which differ in first- and second-line treatments. For each strategy, we simulated healthcare costs and quality of life for a cohort of moderate and severe BPH patients over their lifetime, considering the possibility of treatment-related adverse effects and multiple rounds of retreatment. The incremental cost of a unit improvement in quality of life for a strategy relative to the next most expensive one was compared against a willingness-to-pay threshold to determine cost-effectiveness. We found that WVTT was cost-effective relative to medication as a first-line treatment for patients with moderate or severe BPH, suggesting it represents good value for money and should be considered for subsidy. PUL was not cost-effective as first- nor second-line treatment. TURP is cost-effective as first-line for severe BPH patients only.

Perceptions of primiparous women diagnosed with gestational diabetes mellitus: A descriptive qualitative study.

OBJECTIVE: To understand the perceptions of primiparous women recently diagnosed with Gestational Diabetes Mellitus (GDM) in Singapore. DESIGN: A descriptive qualitative study design. SETTING: An outpatient women's health clinic in a tertiary hospital in Singapore. PARTICIPANTS: Twelve English-speaking primiparous women (aged 27-44 years old) who were diagnosed with GDM were recruited via purposive sampling to participate in this study. METHODS: Face-to-face interviews were carried out with study participants in a private room at the outpatient clinic from December 2019 to May 2021. All interviews were audio-recorded and transcribed verbatim on the same day. Data analysis was guided by Braun and Clarke's thematic analysis framework. FINDINGS: Four main themes were identified from this study's findings: (1) Life leading to GDM: A 'hint' that something was wrong, (2) Reactions to diagnosis: Shock or acceptance, (3) Learning to cope: Facing internal and external challenges, and (4) Living with GDM: A way forward. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Primiparous women with GDM require comprehensive informational, practical, and emotional support to help them manage and accept their condition. Healthcare providers are encouraged to provide individualised and holistic care to these women using a humanistic approach. Accessible online educational resources and peer support services could be considered. Public campaigns to increase the general public's awareness of GDM would also allow future women and their families to be more familiar with the condition and hence more prepared to cope with it.

The societal cost of modifiable risk factors in Singapore.

BACKGROUND: Singapore is one of the most rapidly ageing populations in the world. Nearly half of all disease burdens in Singapore are attributable to modifiable risk factors. This indicates that many illnesses are preventable by modifying behaviours such as increasing physical activity levels or maintaining a healthy diet. Prior cost-of-illness studies have estimated the cost of selected modifiable risk factors. However, no local study has compared costs between groups of modifiable risks. This study aims to estimate the societal cost attributable to a comprehensive list of modifiable risks in Singapore. METHODS: Our study builds on the comparative risk assessment framework from the Global Burden of Disease (GBD) 2019 study. A top-down prevalence-based cost-of-illness approach was undertaken to estimate the societal cost of modifiable risks in 2019. These include healthcare costs from inpatient hospitalisation and productivity losses from absenteeism and premature mortality. RESULTS: Metabolic risks had the highest total cost of US$1.62 billion (95% uncertainty interval [UI] US$1.51-1.84 billion), followed by lifestyle risks of US$1.40 billion (95% UI US$1.36-1.66 billion) and substance risks of US$1.15 billion (95% UI US$1.10-1.24 billion). Across the risk factors, the costs were driven by productivity losses, heavily skewed towards the older working-age group and among males. Most of the costs were driven by cardiovascular diseases. CONCLUSION: This study provides evidence of the high societal cost of modifiable risks and highlights the importance of developing holistic public health promotion programmes. As modifiable risks often do not occur in isolation, implementing effective population-based programmes targeting multiple modifiable risks has a strong potential to manage the cost of the rising disease burden in Singapore.

Optimizing health and nutrition status of migrant construction workers consuming multiple micronutrient fortified rice in Singapore.

INTRODUCTION: A well-nourished workforce is instrumental in eradicating hunger, alleviating poverty, and spurring economic growth. A fifth of the total workforce in high-income countries are migrant workers. Despite the accessibility of nutritious foods in high-income countries, migrant workers often rely on nutrient-poor diets largely consisting of empty calories, which in turn leads to vitamin and mineral deficiency, also called hidden hunger, and resultant productivity loss. Here, we study the magnitude of hidden hunger in male migrant construction workers in Singapore and investigate the impact of consuming fortified rice for 6 consecutive months on the nutrition and health status of these workers. METHODS: 140 male migrant workers aged 20-51 years of either Bangladeshi or Indian ethnicity from a single dormitory in Singapore volunteered to participate in the study. In total, 133 blood samples were taken at the start of the study and were used to assess vitamin B12, hemoglobin, ferritin, folate, and zinc levels; a sub-sample underwent for homocysteine testing. Anthropometric measurements and vital signs, such as blood pressure, were recorded before and after the intervention. RESULTS: The results show that vitamin and mineral deficiency was present, especially folate (59% of workers deficient) and vitamin B12 (7% deficient, 31% marginally deficient). The consumption of fortified rice significantly improved the vitamin, iron and zinc level in the workers and significantly reduced the systolic blood pressure amongst the Bangladeshi migrant workers, specifically. CONCLUSION: Our study demonstrates that fortified rice may have a positive impact on male migrant construction worker health and nutrition status at the workplace.

Community-based end-of-life care in Singapore and nursing care implications for older adults in the post-COVID-19 world.

PURPOSE OF REVIEW: To render holistic overview on community-based end-of-life care in the context of Singapore, with analysis of nursing care implications for older adults requiring end-of-life care services. RECENT FINDINGS: Healthcare professionals caring for older adults with life-limiting conditions had to play an active role in the constantly evolving healthcare landscape during the coronavirus disease 2019 (COVID-19) pandemic. Usual meetings and community-based end-of-life care interventions were converted to online mode, utilizing digital technology. In order to provide value-based and culturally relevant care, further studies are warranted to evaluate healthcare professionals, patients and family caregivers' preferences whilst utilizing digital technology. As a result of COVID-19 pandemic restrictions to minimize infection transmissions, animal-assisted volunteering activities were conducted virtually. Regular healthcare professionals' engagement in wellness interventions is necessary to boost morale and prevent potential psychological distress. SUMMARY: To strengthen the delivery of end-of-life community care services, the following recommendations are proposed: active youth engagement via inter-collaborations and connectedness of community organizations; improving support for vulnerable older adults in need of end-of-life care services; and enhancing healthcare professionals well-being through the implementation of timely support interventions.

Low-Carbohydrate Diet Score and the Risk of Colorectal Cancer: Findings from the Singapore Chinese Health Study.

BACKGROUND: Colorectal cancer is common cancer with a high mortality rate. Low-carbohydrate diet (LCD) score holistically evaluates the LCD pattern from carbohydrate, protein, and fat intake. Epidemiologic data of LCD-colorectal cancer association are sparse. METHODS: We evaluated the associations between LCD (i.e., total, animal- and plant-based) and colorectal cancer risk in the Singapore Chinese Health Study, a population-based prospective cohort study including 61,321 Chinese in Singapore who were 45 to 74 years old at baseline. Cox proportional hazard regression model was used to determine the HRs and respective 95% confidence intervals (CI) for colorectal cancer associated with LCD after adjusting for potential confounders, including age, sex, BMI, physical activity, family history of colorectal cancer, etc. RESULTS: After an average of 19.5 years of follow-up, 2,520 participants developed colorectal cancer (1,608 colon cancer and 912 rectal cancer). Overall, the association between total or plant-based LCD scores with the risk of colorectal, colon, or rectal cancer was null (all Ptrend ≥ 0.28). The animal-based LCD was modestly associated with colon cancer risk (Ptrend = 0.02), but not with rectal cancer. Compared with the lowest quartile, HRs (95% CIs) of colon cancer for quartiles 2, 3, and 4 of animal-based LCD were 1.12 (0.98-1.29), 1.27 (1.10-1.46), and 1.14 (0.99-1.31), respectively. CONCLUSIONS: A low-level carbohydrate diet with a high level of animal protein and fat was associated with a moderate increase in the risk of colon cancer among Chinese Singaporeans. IMPACT: High consumption of animal protein/fat and low consumption of carbohydrates may increase colon cancer risk.

Modifiable Risk Factor Score and Fecundability in a Preconception Cohort in Singapore.

Importance: Although multiple modifiable risk factors have been identified for reduced fecundability (defined as lower probability of conception within a menstrual cycle), no scoring system has been established to systematically evaluate fecundability among females who are attempting to conceive. Objective: To examine the association of a risk score based on 6 modifiable factors with fecundability, and to estimate the percentage reduction in incidence of nonconception if all study participants achieved a minimal risk score level. Design, Setting, and Participants: This population-based cohort study obtained data from the S-PRESTO (Singapore Preconception Study of Long-Term Maternal and Child Outcomes) prospective cohort study. Females of reproductive age who were trying to conceive were enrolled from February 2015 to October 2017 and followed for 1 year, ending in November 2018. Data were analyzed from March to May 2022. Exposures: A reduced fecundability risk score was derived by giving participants 1 point for each of the following factors: unhealthy body mass index, unhealthy diet, smoking, alcohol intake, folic acid supplement nonuser, and older maternal age. Total scores ranged from 0 to 6 and were classified into 5 levels: level 1 (score of 0 or 1), level 2 (score of 2), level 3 (score of 3), level 4 (score of 4), and level 5 (score of 5 or 6). Main Outcomes and Measures: Fecundability, measured by time to conception in cycles, was analyzed using discrete-time proportional hazards models with confounder adjustment. Results: A total of 937 females (mean [SD] age, 30.8 [3.8] years) were included, among whom 401 (42.8%) spontaneously conceived within 1 year of attempting conception; the median (IQR) number of cycles before conception was 4 (2-7). Compared with participants with a level 1 risk score, those with level 2, 3, 4, and 5 risk scores had reductions in fecundability of 31% (adjusted fecundability ratio [FR], 0.69; 95% CI, 0.54-0.88), 41% (FR, 0.59; 95% CI, 0.45-0.78), 54% (FR, 0.46; 95% CI, 0.31-0.69) and 77% (FR, 0.23; 95% CI, 0.07-0.73), respectively. Assessment of the population attributable fraction showed that all participants achieving a minimal (level 1) risk level would be associated with a reduction of 34% (95% CI, 30%-39%) in nonconception within a year. Conclusions and Relevance: Results of this study revealed the co-occurrence of multiple modifiable risk factors for lowered fecundability and a substantially higher conception rate among participants with no or minimal risk factors. The risk assessment scoring system proposed is a simple and potentially useful public health tool for mitigating risks and guiding those who are trying to conceive.

Smoking, but not use of complementary and alternative medicine predicts residual functional disability in patients with inflammatory arthritis on biologic disease-modifying anti-rheumatic drugs: Results from the Singapore National Biologics Register.

AIMS: To describe inflammatory arthritis (IA) patients initiating biologic disease-modifying anti-rheumatic drugs (bDMARDs) who use complementary and alternative medicine (CAM), and determine the impact of CAM on predicting modified Health Assessment Questionnaire (mHAQ) at 6 months. METHODS: This was a prospective inception cohort study of patients ≥21 years old initiating a bDMARD for IA after July 2016. Data were obtained via questionnaires and abstraction from medical records. Baseline characteristics between ever-CAM and CAM non-users were compared. CAM as a predictor of mHAQ ≥1 at 6 months after bDMARD initiation was analyzed using multivariate logistic regression, adjusting for other baseline characteristics. RESULTS: We recruited 299 patients (36.2% male, mean age 49.0 years). There were 45.8% who had rheumatoid arthritis, 54.2% had a spondyloarthropathy, median disease duration of 1.1 years and median mHAQ of 0.4. Compared to CAM non-users, ever-CAM users had a lower mean body mass index, were less likely to speak English, and more likely to smoke and drink alcohol. There was no association of CAM use with high mHAQ and no interaction with smoking. Smoking (odds ratio [OR] 938.9; 95% CI 3.20-275 884.1), baseline mHAQ (OR 252.2; 95% CI 5.34-11 899.2) and Charlson's Comorbidity Index score ≥4 (OR 237.4; 95% CI 1.22-46 184.4) independently predicted high mHAQ at 6 months. CONCLUSIONS: CAM use was not associated with high mHAQ at 6 months. Smoking was an independent predictor of residual functional disability at 6 months, even after adjusting for age, comorbidity and baseline mHAQ. Greater emphasis on smoking cessation may improve long-term functional outcomes in IA patients on bDMARDs.

Continuity of Care Advocate Model (CCAM): Healthcare Workers' Perspectives on Quality Stroke Care at an Acute Unit, Rehabilitation Center and Community Rehabilitation Program in Singapore.

Physicians, nurses, social workers, and allied health professionals including physiotherapists and occupational therapists play important roles as they work closely with stroke survivors to improve functional independence in daily activities and quality of life. Yet, in Singapore little is known about their perspectives on what constitute quality stroke care based on their clinical experiences. In this project, our qualitative interviews with 15 healthcare workers at a major stroke center in the country yielded a Continuity of Care Advocate Model (CCAM) to help us better understand our participants' experience-based perspectives on quality stroke care. We found that CCAM, constructed based on the perspectives of HCWs across a stroke care continuum, is a holistic model of quality stroke care which prioritizes support for patients and their families throughout the patient's health trajectory. We conclude by discussing how this model is aligned with and differs from current research on definitions of care continuity.

A hospital-based return-to-work programme in Singapore.

Return to Work (RTW) programmes have become imperative in manpower scarce countries. This paper describes a RTW programme in a Singapore tertiary hospital, reports patient outcomes and discusses the practicality and effectiveness of the programme. Seventy-three workers participated in the programme over a two-year period. A statistically significant increase in work ability and self-perceived overall health status from first contact with worker (baseline) to discharge was observed. Continued programme participation till first RTW was associated with higher work ability and self-perceived overall health status at baseline. The RTW Coordinator-anchored multidisciplinary model which provided holistic support to the worker and addressed stakeholder interests were central to the programme's success. Greater awareness of RTW programme benefits will improve sustained participation. Our RTW programme features, implementation experiences and participant reported effectiveness may inform the development of improved return to work models.

Spirit Mediumship and Mental Health: Therapeutic Self-transformation Among Dang-kis in Singapore.

While some early studies suggested that spirit mediums were psychiatrically ill individuals who found a culturally sanctioned role, subsequent work has found that they are generally in good physical and mental health. While the calling to be a healer often involves an initiatory illness, practitioners go on to play demanding social roles, suggesting that involvement in mediumship may be therapeutic for the practitioner. This study focuses on dang-ki healing, a form of Chinese spirit mediumship practiced in Singapore to explore whether participation in dang-ki healing is therapeutic for the mediums. We interviewed eight dang-kis from five temples about their life trajectories and assessed their mental health status with standardized psychological questionnaires. Most of the dang-kis did not appear to suffer from clinically significant emotional distress. Their narratives suggest that involvement in dang-ki mediumship may have therapeutic effects in which the embodied experience of self plays a central role. The dang-kis experienced changes in social identity, bodily experiences during spirit possession, and their overall sense of self through recurrent possession rituals. In general, the practice of spirit mediumship illustrates how the experiences and meanings of the self are constructed and reconstructed through body-world relations in ways that may confer a sense of wellness and social efficacy.

Connecting the dots: The state of arts and health in Singapore.

Background: This article examines the state of the field of arts and health in Singapore and identifies the drivers that have shaped its development to date, adding new insights from Asia to the growing international literature in this area. Methods: Various methods, including an online survey and in-depth focus groups were used. Results: We find that the field in Singapore is rapidly growing, with a proliferation of activities across the arts and culture, healthcare, and social care sectors in recent decades fostered by various policy developments, increased funding and new peer-to-peer networking. Nevertheless, several issues persist, including inconsistent understanding and conceptualisation of the field as a whole across multiple stakeholders, limited research capacity and training platforms, and lack of professional recognition. Conclusions: We provide recommendations for further action, including developing arts and health literacy and research capacity, investing in efforts to bridge education and practice, and focusing on formalising and elevating professional standards.

The Association of Sudarshan Kriya Yoga with Happiness: A Case-Control Observational Study from Singapore.

Happiness is a complex subjective experience that is essential to societal progress. This study investigated the association between Sudarshan Kriya Yoga (SKY) and subjective happiness in Singapore. Subjective happiness data were collected from a convenience sample (N = 733) comprised of 2 groups: SKY (n = 385) and non-SKY (n = 348) practitioners. SKY was categorized into non-, monthly, weekly, and daily practitioners and happiness was categorized into lower, middle and higher tertile groups. Confounding variables included age, gender, ethnicity, marital status, education level, body mass index (BMI), smoking status, alcohol consumption and self-reported health. Daily SKY participation was positively associated with a 2-fold higher likelihood of being happier in a multivariate regression analysis. The trend analysis showed that as SKY frequency increases, the odds of being happier increases. These findings help generate the hypothesis that yogic breathing may promote happiness. Further experimental and prospective investigations are warranted.

Chronic low back pain and its impact on physical function, mental health, and health-related quality of life: a cross-sectional study in Singapore.

Chronic low back pain, defined as low back pain lasting more than 3 months, is a globally prevalent health problem with significantly high medical and economic burden on individuals and the society. This study aimed to estimate the prevalence of chronic low back pain and examine its association with health outcomes including physical function, mental health, and quality of life among adult population in Singapore. Cross-sectional secondary data analysis was performed using baseline data of the 1941 adults (mean age: 52.6 years, range: 21-97 years) from a representative population health survey conducted in the Central region of Singapore. Those with self-reported chronic low back pain in past six months were identified. The Late-Life Function and Disability Instrument, Patient Health Questionnaire-9, and EQ-5D-5L were used to measure physical function and limitation, mental health, and health-related quality of life, respectively. Generalized Linear Regressions were used to examine the association of chronic low back pain with physical function, limitation, depressive symptoms, and health-related quality of life. There were 8.1% (n = 180) participants reporting having chronic low back pain in past six months, among whom 80.5% sought treatments at either primary care, specialist outpatient, or Traditional Chinese Medicine clinics. Individuals with chronic low back pain reported poorer physical function, more limitations in performing major life tasks and social activities, more depressive symptoms, and lower health-related quality of life (all p < 0.01), even after adjusting for socio-demographics, lifestyle factors, and number of morbidities. The prevalence of chronic low back pain was 8.1% among the study population. Chronic low back pain was associated with poorer physical function, more limitations and depressive symptoms, and lower health-related quality of life. The findings highlight the significant impact of chronic low back pain on physical function and limitation, mental health, and health-related quality of life in a general population. Increased awareness on prevention, early and proper management of low back pain, and rehabilitation policies are required to better tackle the burden of low back pain at the population level.

Singapore Clinical Practice Guidelines For Sarcopenia: Screening, Diagnosis, Management and Prevention.

OBJECTIVES: To present the local evidence and final recommendations of the Clinical Practice Guidelines workgroup convened by the Chapter of Geriatricians and the Society for Geriatric Medicine Singapore. The aim is to develop contextualized evidence-based recommendations that facilitate adoption of the Asian Working Group for Sarcopenia (AWGS) 2019 consensus into current practice in Singapore. METHODS: The workgroup drew upon the AWGS'2019 consensus, updated literature review of Singapore studies till 31 Dec 2020, and evidence from recent systematic reviews. From 40 local studies included for data extraction, we constructed evidence tables organized as: definition and epidemiology; diagnosis and evaluation; and treatment and intervention. Twenty recommendations - case-finding, diagnosis, treatment, prevention, research - were developed, and graded for strength and quality using the GRADE approach. Consensus from an expert panel(N=23) was achieved after two rounds of the modified Delphi process. RESULTS: The local prevalence of sarcopenia among community-dwelling older adults ranged from 13.6% to 25%. Most studies adopted the AWGS'2019 and AWGS'2014 criteria. Reported case finding tools include SARC-F, calf circumference (CC) and SARC-CalF. Gender-specific AWGS cut-offs for appendicular skeletal mass were used to define low muscle mass. Different protocols and dynamometers were used to assess handgrip strength, whilst gait speed and 5-times chair stand were commonly used to assess physical performance. RECOMMENDATIONS: We conditionally recommend a case-finding approach in at-risk older adults using validated case-finding tools. Screen-positive individuals should be assessed for 'possible sarcopenia' and underlying causes. For diagnosis, we conditionally recommend using the AWGS'2019 algorithm, and dual-energy X-ray absorptiometry when necessary to determine low lean mass for a confirmatory diagnosis of sarcopenia. For treatment, we strongly recommend resistance-based exercises and conditionally recommend a quality protein-rich diet/protein supplementation, with Vitamin D supplementation for insufficiency (<30 micrograms/L). For prevention, we recommend regular resistance-based physical activity and adequate protein intake (≥1.0g/kg bodyweight). We encourage more research to address local evidence gaps.
