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:
This study was performed to evaluate the antiadhesive effect and safety of a novel adhesion barrier device (ABD) in comparison to other commercially available anti-adhesion products.
Methods:
A 4-arm, controlled, blinded, experimental, and murine model study design was used. Forty male Sprague Dawley rats were randomly allocated to Interceed, Seprafilm, ABD, and control groups (n = 10/group). Abdominal cavity trauma was induced in all rats. Interceed, Seprafilm, or the ABD were applied to the injury site of each rat according to their respective groups, the control group received no intervention.
Results:
Twenty-one days after the operation, surgical adhesion severity and area scores were significantly reduced in the Interceed, Seprafilm, and ABD groups compared to the control group (P = 0.016, P < 0.001, P < 0.001, respectively), and in the ABD group compared to the Interceed group (P = 0.036). No significant difference was observed between the ABD and Seprafilm groups (P = 0.070). Additionally, in the ABD group, no remnants of the ABD were observed at the injury site, and no hematological abnormalities were present.
Conclusion
The ABD has the potential to improve postsurgical peritoneal adhesions compared to Interceed and has comparable effectiveness compared to Seprafilm. The ABD may be a valuable option to reduce surgical failure. Further studies in human subjects are warranted to determine the clinical application and safety of the ABD for commercialization.

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:
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.
