METHODS: We utilised systematic random sampling by recruiting every 25th patient registered in our clinic during data collection. Participants answered a self-administered printed questionnaire regarding their smartphone usage and familiarity with QR code scanning at the patients' waiting area. Data were analysed using the Statistical Package for the Social Sciences version 26.
RESULTS: A total of 323 patients participated (response rate=100%). The participants' median age was 57 years (interquartile range=4l-67). Most participants were women (63.1%). Approximately 90.4% (n=282) used smartphones, with 83.7% (n=261) reporting average or good usage proficiency. More than half (58.0%) accessed medical information via their smartphones, and 67.0% were familiar with QR codes. Multiple logistic regression analyses revealed that familiarity with QR codes was linked to age of <65 years [adjusted odds ratio (AOR)=4.593, 95% confidence interval (CI)=2.351-8.976, P<0.001], tertiary education (AOR=2.385, 95% CI=1.170-4.863, P=0.017), smartphone proficiency (A0R=4.703, 95% CI= 1.624-13.623, P=0.004) and prior smartphone usage to access medical information (AOR=5.472, 95% CI=2.790-10.732, P<0.001).
CONCLUSION: Since smartphones were accessible to most primary care patients, and more than half of the patients were familiar with QR code scanning, QR code-based quality improvement projects can be used to improve services in our setting.
METHODS: A cross-sectional online survey was conducted from February to April 2021 among adolescents in Kota Bharu, Kelantan. Participants completed the Malay Version of the Internet Addiction Test, the Depression, Anxiety and Stress Scale-21 and a sociodemographic information form. A multiple logistic regression analysis was performed to determine the associations between variables.
RESULTS: A total of 535 adolescents participated in this study. Among them, 65.9% were girls. The prevalence of IA among the participants was 48.6%. Male sex [adjusted odds ratio (AOR)=2.15, 95% confidence interval (CI)=1.30-3.57], internet usage at home (AOR=6.17, 95% CI=1.94-19.58), internet usage to watch/download music (AOR=2.50, 95% CI= 1.52-4.12), internet usage to engage in social networking (AOR=2.29, 95% CI=1.19-4.40), inadequate parental/guardian bonding (AOR=2.19, 95% CI=1.31-3.65), depression (AOR=2.03, 95% CI=1.07-3.85), anxiety (AOR=2.79, 95% CI=1.64-4.76) and stress (AOR=4.67, 95% CI=2.00-10.91) were significantly associated with IA.
CONCLUSION: IA was prevalent among Malaysian adolescents during the COVID-19 pandemic. Sex, internet usage profile and psychological factors were significant predictors of IA.
METHODS: From 1 January to 31 December 2023, this cross-sectional study examined 119 Malaysian adolescent karate athletes aged 13-19 years. Data on demographic characteristics and patterns of injuries were collected using a standardised form and analysed using SPSS version 26.
RESULTS: The incidence of injuries was 22.3 injuries per 1000 athlete exposures. Specifically, the incidence of injuries during training was 15.34 injuries per 1000 athlete exposures, while that during competition was 106.6 injuries per 1000 athlete exposures. The majority of the injuries were mild (n=113, 87.6%), while the minority were severe (n=6, 4.7%). The injuries most commonly occurred in the head and neck (n=31, 24%), followed by the ankle (n=13, 10.1%) and foot (n=14, 10.9%).
CONCLUSION: There is a need to explore the extrinsic and intrinsic risk factors of injuries among adolescent karate athletes in Malaysia, as the incidence of injuries is high during competition. Additionally, it is important to educate athletes and supporting sports science members about injury prevention programmes.
METHODS: A comprehensive literature search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines across the PubMed, SCOPUS, Web of Science, and SPORTDiscus databases until December 31, 2023. The inclusion criteria for this review encompassed research articles published in peer-reviewed journals that specifically focused on the impact of HIIT on the oxygen consumption performance of male players engaged in team sports. The study population exclusively consisted of male participants. The collected data included study characteristics, participant demographics, intervention details, and outcomes. Methodological quality assessment was performed using standardized criteria. The effect sizes (ESs) were calculated, and a meta-analysis was conducted using a random-effects model.
RESULTS: The literature search yielded 13 eligible studies encompassing 286 athletes aged 14-26 years. The meta-analysis showed statistically significant enhancements in maximal oxygen uptake (VO2max) in six studies (ES, 0.19-0.74; p < 0.005), Yo-Yo Intermittent Recovery Test (YYIRT) performance in six studies (ES, 0.20-2.07; p = 0.009), repeated-sprint ability total time (RSAtotal) in five studies (ES, 0.18-1.33; p < 0.001), and the best and average times for repeated-sprint ability (RSAbest and RSAmean, respectively) in four studies (ES, 0.47-1.50; p < 0.001). However, two studies did not report any significant differences in the outcomes of the Velocity in 30-15 Intermittent Fitness Test (VIFT) between the experimental and control groups (ES, -0.08 and -0.27; p = 0.87 and 0.443, respectively). Moreover, one study did not report any significant differences in the maximal aerobic speed (MAS) (ES, 0.41, p = 0.403).
CONCLUSIONS: HIIT significantly improved VO2max, YYIRT, and RSA; however, it did not appear to enhance VIFT and MAS performance, irrespective of age or competition level. These findings indicate that HIIT could serve as a valuable method for improving oxygen consumption performance (VO2max, YYIRT, and RSA) in male team-sport athletes, offering a time-efficient alternative to the traditional training methods. Further research is warranted to investigate its impact on performance outcomes in competitive settings and identify optimal HIIT protocols tailored to specific team sports.
METHODS: A systematic search of PubMed, EMBASE, and Web of Science was conducted up to June 7, 2024, following PRISMA guidelines to identify studies related to COVID-19 vaccines and POTS. Eligible studies included randomized controlled trials, cohort studies, cross-sectional studies, case-control studies, case series, and case reports. Screening, data extraction, and quality assessment were independently performed by two reviewers using the Joanna Briggs Institute Checklists and the Newcastle-Ottawa Scale.
RESULTS: Of the 1,531 articles identified, 10 met the inclusion criteria, encompassing a total of 284,678 participants. These studies included five case reports, two case series, one cross-sectional study, one prospective observational study, and one cohort study. The cohort study reported that the odds of new POTS diagnoses post-vaccination were 1.33 (95% CI: 1.25-1.41) compared to the 90 days prior. In contrast, the post-infection odds were 2.11 (95% CI: 1.70-2.63), and the risk of POTS was 5.35 times higher (95% CI: 5.05-5.68) post-infection compared to post-vaccination. Diagnostic findings across studies included elevated norepinephrine levels and reduced heart rate variability. Reported management strategies involved ivabradine, intravenous therapies, and lifestyle modifications.
CONCLUSION: The risk of POTS following COVID-19 vaccination is lower than that observed post-SARS-CoV-2 infection; however, existing studies are limited by small sample sizes and methodological variability. Further research is needed to clarify the incidence, mechanisms, and long-term outcomes of vaccine-related POTS to inform effective clinical management strategies.
METHODS: Twenty-five P. knowlesi samples collected in 2018-2023 were sequenced for the 42-kDa region of pkmsp1 and compared with 24 retrieved sequences in 2000-2009, focusing on nucleotide diversity, natural selection, recombination rate, and population differentiation.
RESULTS: Seven unique haplotypes were identified in recent samples, compared to 15 in earlier samples. Nucleotide and haplotype diversity were lower in recent samples (π = 0.016, Hd = 0.817) than in earlier samples (π = 0.018, Hd = 0.942). Significantly higher synonymous substitution rates were observed in both sample sets (dS-dN = 2.77 and 2.43, p
