Public interest in cognitive enhancement has driven the widespread availability of dietary supplements claiming
to support brain health and memory. This comparative cross-sectional study explores the commercial availability
and marketing claims of cognitive-enhancing dietary supplements across offline and online retail platforms.
A dual-component design was employed in a comparative cross-sectional study. The first component involved
assessing the commercial availability and marketing claims of cognitive-enhancing dietary supplements sold
through offline retail outlets in Kuala Lumpur using a purposive sampling approach. The second component
consisted of a parallel assessment conducted on online platforms, employing a convenience sampling strategy. A
total of 13 products were identified on offline retail platforms in Kuala Lumpur, and 117 products were identified
on online platforms. Capsules were the most common dosage form, both offline (46.2%) and online (79.5%).
Products sold offline most frequently originated from Singapore (69.2%), whereas online products predominantly
came from the United States of America (74.4%). The median prices of offline products were RM 190 (55.5), and
online products were RM 196 (183), which are comparable, although the online products exhibited a wider price
range (RM14–RM1,147). The most frequent claims were “brain health” for offline products and “memory” for
online products. Natural or compound extracts were the most common active ingredients. This study’s findings
found significant differences between offline and online dietary supplements in terms of availability, country of
origin, price and marketing claims. These inconsistent findings underscore the need for stronger regulation and
improved transparency in labelling to safeguard consumer health and ensure product credibility. Future research
should focus on dosage accuracy, long-term safety, and mechanisms of action for supplements with cognitiveenhancing claims.

Purpose:
To characterize the patterns of demographic data, dermatologic diagnosis, and disposition regarding pediatric dermatological presentations in an emergency department (ED) at Armadale Health Service, a secondary outer metropolitan hospital in Perth, Western Australia.
Methods:
Retrospective cross-sectional study auditing pediatric dermatological presentations to the ED from December 2022 through November 2023. We analyzed the age group, sex, dermatologic diagnosis, Australasian Triage Scale, ED length of stay, and disposition. The age group comprised infants, preschoolers, schoolers, and adolescents. The diagnosis included anaphylaxis and angioneurotic edema (AAE), allergy-related and urticarial dermatitis (AUD), eczema and other dermatitis (EOD), infective dermatoses, and not elsewhere classified.
Results:
Of the 540 pediatric patients who presented to the ED with a dermatological complaint, 44.4% were girls with a median age of 4.5 years (interquartile range, 1.5-9.3) and a hospitalization rate of 7.6%. The dermatologic diagnoses consisted of AUD (34.3%), infective dermatoses (29.3%), EOD (23.3%), AAE (8.5%), and not elsewhere classified (4.6%). Most patients were triaged as an Australasian Triage Scale category 3-4, with a median ED length of stay of 2.3 hours (1.5-3.5 hours). Pairwise comparisons showed differences in the diagnoses between infants and preschoolers and between schoolers and adolescents for EOD and infective dermatoses (P < 0.001). The hospitalized patients showed a higher proportion of AAE, EOD, and infective dermatoses than those discharged (P < 0.001). Patients with AUD were hospitalized less (odds ratio, 0.06; 95% confidence interval, 0.12-0.30; compared with AAE). No dermatological emergencies, such as Stevens-Johnson syndrome, were identified.
Conclusion
Our findings underscore regional differences and support global efforts to reduce non-life-threatening pediatric dermatological presentations to the ED. This study may contribute to the ongoing discourse on effectively managing such presentations in EDs.

INTRODUCTION:
Adolescent depression is prevalent, and teen suicide rates are on the rise locally. A systemic review to understand associated risk and protective factors is important to strengthen measures for the prevention and early detection of adolescent depression and suicide in Singapore. This systematic review aims to identify the factors associated with adolescent depression in Singapore.
METHODS:
A systematic search on the following databases was performed on 21 May 2020: PubMed, EMBASE and PsycINFO. Full texts were reviewed for eligibility, and the included studies were appraised for quality using the Newcastle Ottawa Scale. Narrative synthesis of the finalised articles was performed through thematic analysis.
RESULTS:
In total, eight studies were included in this review. The four factors associated with adolescent depression identified were: (1) sociodemographic factors (gender, ethnicity); (2) psychological factors, including childhood maltreatment exposure and psychological constructs (hope, optimism); (3) coexisting chronic medical conditions (asthma); and (4) lifestyle factors (sleep inadequacy, excessive internet use and pathological gaming).
CONCLUSION
The identified factors were largely similar to those reported in the global literature, except for sleep inadequacy along with conspicuously absent factors such as academic stress and strict parenting, which should prompt further research in these areas. Further research should focus on current and prospective interventions to improve mental health literacy, targeting sleep duration, internet use and gaming, and mitigating the risk of depression in patients with chronic disease in the primary care and community setting.

INTRODUCTION:
Cancer patients attending emergency departments (EDs) often present with acute symptoms and are frequently admitted. This study aimed to characterise the profile of oncology patients who were discharged from the ED.
METHODS:
This was a retrospective audit of patients with cancer-related diagnoses who presented to the ED at the Singapore General Hospital (SGH) over a 6-month period from 1 October 2018 to 31 March 2019 and were directly discharged from the ED. Data was extracted from the hospital's electronic medical record system.
RESULTS:
Of the 492 participants included in the study, the majority were triaged as Priority 2 (61.4%), while 30.7% were triaged as Priority 3, 6.9% as Priority 1 and 1.0% as Priority 4. There was no statistical difference between the National Early Warning scores across the different triage categories in these patients. The most common complaint was (44.3%), followed by genitourinary symptoms (19.5%) and those related to devices, catheters or stomas (17.3%). More investigations of all types were done for patients being managed in Priority 1 (57.6%) than in the other triage categories (40.1% for Priority 2, 23.2% for Priority 3 and 12.0% for Priority 4). Treatment procedures carried out were mainly symptomatic (analgesics, antiemetics, proton pump inhibitors) for 79.8% of the patients. There were no significant differences in the proportion of patients requiring various treatment modalities among the triage categories.
CONCLUSION
Selected oncological patients may potentially be managed in an ambulatory setting.

INTRODUCTION:
Degenerative mitral stenosis (DMS) is frequently cited as increasing in prevalence in the developed world, although comparatively little is known about DMS in comparison to rheumatic mitral stenosis (RMS).
METHOD:
A retrospective observational study was conducted on 745 cases of native-valve mitral stenosis (MS) with median follow-up time of 7.25 years. Clinical and echocardiographic parameters were compared. Univariate and multivariate Cox regression analyses were performed for a composite of all-cause mortality and heart failure hospitalisation.
RESULTS:
Patients with DMS compared to RMS were older (age, mean ± standard deviation: 69.6 ± 12.3 versus [vs] 51.6 ± 14.3 years, respectively; P<0.001) and a greater proportion had medical comorbidities such as diabetes mellitus (78 [41.9%] vs 112 [20.0%], P<0.001). The proportion of cases of degenerative aetiology increased from 1.1% in 1991-1995 to 41.0% in 2016-2017. In multivariate analysis for the composite outcome, age (hazard ratio [HR] 95% confidence interval [CI] of 1.032 [1.020-1.044]; P<0.001), diabetes mellitus (HR 1.443, 95% CI 1.068-1.948; P=0.017), chronic kidney disease (HR 2.043, 95% CI 1.470-2.841; P<0.001) and pulmonary artery systolic pressure (HR 1.019, 95% CI 1.010- 1.027; P<0.001) demonstrated significant indepen-dent associations. The aetiology of MS was not independently associated with the composite outcome.
CONCLUSION
DMS is becoming an increasingly common cause of native-valve MS. Despite numerous clinical differences between RMS and DMS, the aetiology of MS did not independently influence a composite of mortality or heart failure hospitalisation.

INTRODUCTION:
While traditional Chinese medicine (TCM) has a long history and continues to be widely practised, its overall clinical efficacy according to conventional scientific standards remains the topic of ongoing research and exploration. This review focuses on the potential use of acupuncture and Chinese herbal medicine (CHM) in combination with Western medicine in Singapore, based on recently published data on the clinical effectiveness and cost-effectiveness of these TCM treatments.
METHOD:
We collated and summarised 71 research papers published in the past decade, focusing on randomised controlled trials, systematic reviews and population-based cohort studies that had a total sample size (treatment and control arms) exceeding 60. English-language articles published between 2015 and 2025 were identified by searching PubMed/MEDLINE, the Cochrane Library and the China National Knowledge Infrastructure. The search strategy included intervention terms like "acupuncture", "Chinese medicine", "TCM", "traditional Chinese medicine", "RCT" and "randomized controlled trial"; economic evaluation terms like "cost" and "cost-effectiveness"; and disease conditions of concern. We narrowed our research to the clinical effectiveness and cost-effectiveness of CHM in which either the individual ingredients or the products were listed as Chinese Proprietary Medicines (CPMs).
RESULTS:
The summary tables demonstrate that the integration of acupuncture and/or CPMs with conventional Western medicine can enhance treatment outcomes across various chronic and non-chronic diseases. Their affordability and preventive focus can contribute to long-term healthcare cost savings, benefiting both patients and the healthcare system as a whole.
CONCLUSION
With a robust regulatory framework, scientific validation and government support, acupunc-ture and CPMs have an important role in the management of various diseases, especially chronic ones, in Singapore.
