Caregiver burden, mental health, quality of life and self-efficacy of family caregivers of persons with dementia in Malaysia: baseline results of a psychoeducational intervention study.

BACKGROUND: The majority of persons with dementia (PWD) are mainly cared for by their family members in the home. Evidence is however scarce on family caregivers' psychosocial burden and quality of life in Asian countries including Malaysia. This study describes the baseline data of a telephone-delivered psychoeducational intervention study and examines the determinants of outcome measures (caregiver burden, depressive and anxiety symptoms, quality of life and caregiving self-efficacy) among Malaysian family caregivers to PWD. METHODS: This was a cross-sectional study originated from the baseline survey of a randomized control trial of 121 family caregivers recruited from lists of PWD who were registered at memory and psychiatry clinics in three tertiary care hospitals in Malaysia. The participants were assessed for caregiver burden by the Zarit Burden Interview, depressive and anxiety symptoms by the Hospital Anxiety and Depression Scale, quality of life by the Control, Autonomy, Self-Realization, and Pleasure Scale, and caregiving self-efficacy by the Revised Scale for Caregiving Self-Efficacy. RESULTS: Prevalence of caregiver burden was 69.4%, depressive symptoms 32.2% and anxiety symptoms 32.2%. Family caregivers to PWD having perceived peer support e.g., social/family/friend/significant other supports were less likely to report caregiver burden, depressive and anxiety symptoms, and more likely to report higher levels of quality of life and caregiving self-efficacy. Being married and PWD's ability to self-care were associated with lesser likelihood of experiencing caregiver burden, depressive and anxiety symptoms. The other determinants of greater probability of reporting better quality of life were caregivers' employment and having Islamic faith. Marital status (married), PWD's ability to self-care, spousal relationship with PWD and shared caregiving process were associated with higher likelihood of reporting caregiving self-efficacy. CONCLUSION: Caregiver burden, depressive and anxiety symptoms are prevalent in family caregivers to PWD in Malaysia. Social support and caregiving related factors influence family caregivers' quality of life and caregiving self-efficacy. Implementing psychoeducational intervention and support in the psychiatry and memory clinics may help improve the psychosocial burden, quality of life and caregiving self-efficacy in family caregivers of PWD. TRIAL REGISTRATION: ISRCTN14565552 (retrospectively registered).

Nirmatrelvir/ritonavir treatment and the risk of post-COVID condition over 180 days in Malaysia.

BACKGROUND: The effect of nirmatrelvir/ritonavir on preventing post-COVID condition (PCC) in the BA4, BA5, and XBB Omicron predominant periods is not well understood. The purpose of this study was to assess how nirmatrelvir/ritonavir treatment affected both PCC and health-related quality of life. METHODS: This retrospective cohort study enrolled 2,524 adults aged 18 years and older who were eligible for nirmatrelvir/ritonavir between July 14 to November 14, 2022. All outcomes were observed from the patient's first visit to the primary health clinic, 1 week, 1 month, 3 months, and 6 months after testing positive for COVID-19. The primary outcome was the presence of PCC. Secondary outcomes included the effects on health-related quality of life, such as walking, bathing and dressing, activities, cause adverse emotions or signs that prevent individuals from leading normal lives over a 180-day observation period. RESULTS: There were no significant differences observed between the nirmatrelvir/ritonavir and those not administered (control group) in terms of PCC symptoms at 3 months (OR 0.71 95% CI 0.31, 1.64) and 6 months (OR 1.30 95% CI 0.76, 2.21). At 3 months, the use of nirmatrelvir/ritonavir was associated with a 26% reduction in symptoms causing negative emotions (OR 0.74 95% CI 0.60, 0.92) and an increased likelihood of symptoms limiting walking (OR 1.58 95% CI 1.10, 2.27). However, there were no significant differences between the nirmatrelvir/ritonavir and the control group in terms of the impact of PCC on health-related quality of life at 6 months. CONCLUSIONS: Our study indicates that the administration of nirmatrelvir/ritonavir does not significantly reduce PCC after 3 months and 6 months in a population with high vaccination coverage.

Body fat distribution and bone mineral density in a multi-ethnic sample of postmenopausal women in The Malaysian Cohort.

In this study of postmenopausal women in Malaysia, total adiposity was inversely associated with total BMD, while regional associations varied. No differences were detected across Malay, Chinese, and Indian ethnicities. Low BMD contributes substantially to morbidity and mortality, and increasing adiposity levels globally may be contributing to this. PURPOSE: To investigate associations of total and regional adiposity with bone mineral density (BMD) among a multi-ethnic cohort of postmenopausal women. METHODS: Dual X-ray absorptiometry (DXA) imaging was undertaken for 1990 postmenopausal women without prior chronic diseases (30% Malay, 53% Chinese, and 17% Indian) from The Malaysian Cohort (TMC). The strength of the associations between standardized total and regional body fat percentages with total and regional BMD was examined using linear regression models adjusted for age, height, lean mass, ethnicity, education, and diabetes. Effect modification was assessed for ethnicity. RESULTS: Women with a higher total body fat percentage were more likely to be Indian or Malay. Mean (SD) BMD for the whole-body total, lumbar spine, leg, and arm were 1.08 (0.11), 0.96 (0.15), 2.21 (0.22), and 1.36 (0.12) g/cm2, respectively. Total body and visceral fat percentage were inversely associated with total BMD (- 0.02 [95% CI - 0.03, - 0.01] and - 0.01 [- 0.02, - 0.006] g/cm2 per 1 SD, respectively). In contrast, subcutaneous and gynoid fat percentages were positively associated with BMD (0.007 [0.002, 0.01] and 0.01 [0.006, 0.02] g/cm2, respectively). Total body fat percentage showed a weak positive association with lumbar BMD (0.01 [0.004, 0.02]) and inverse associations with leg (- 0.04 [- 0.06, - 0.03]) and arm (- 0.02 [- 0.03, - 0.02]) BMD in the highest four quintiles. There was no effect modification by ethnicity (phetero > 0.05). CONCLUSION: Total adiposity was inversely associated with total BMD, although regional associations varied. There was no heterogeneity across ethnic groups suggesting adiposity may be a risk factor for low BMD across diverse populations.

Natural health product knowledge as a significant factor associated with health-promoting lifestyle in a low-income urban community in Kuala Lumpur.

BACKGROUND: Low income communities are vulnerable to non-communicable diseases (NCDs), which affect their economy and disability status. An effective approach to address the NCD burden is through the multidimensional concept of health-promoting lifestyle. Another preferred approach by the population worldwide for NCD treatment is natural health product (NHP). Studies on NHP and health-promoting lifestyle among this vulnerable population, specifically the low-income urban community, are limited. Therefore, this study, aimed at investigating the NHP knowledge and health-promoting lifestyle, and to determine the factors associated with health-promoting lifestyle in a low income urban community in Cheras, Kuala Lumpur. This study has focused on sociodemographic characteristics, annual health monitoring activities, and health status, which are modifiable and non-modifiable factors. METHODS: Phase 1 of the study involves developing the Malay-version NHP knowledge questionnaire, whereas Phase 2 involves a cross-sectional study of 446 randomly selected low-income respondents to determine their level of health-promoting lifestyle and the associated factors. The respondents' sociodemographic, socioeconomic, health monitoring activity, health status, and NHP knowledge data were obtained using the newly developed Malay-version NHP questionnaire and the Health-Promoting Lifestyle Profile II (HPLP II) questionnaire. The independent variables include sociodemographic status, annual health monitoring activities, health status and NHP knowledge were analysed using simple and multiple linear regression. RESULTS: In this study, the 10-item NHP knowledge questionnaire developed in the Malay version contains two domains [safe use (eight items) and point of reference (two items)] (total variance explained: 77.4%). The mean of NHP knowledge score was 32.34 (standard deviation [SD] 7.37). Meanwhile, the mean score of health-promoting lifestyle was 109.67 (SD 25.01). The highest and lowest scores of health-promoting lifestyles are attributed to spiritual growth and physical activity, respectively. Ethnicity is associated with a higher health-promoting lifestyle level, same goes to the occupational status - NHP knowledge interaction. "Unclassified" education status and annual blood glucose level monitoring are associated with a lower level of health-promoting lifestyle. CONCLUSION: A new questionnaire in Malay version was developed to measure NHP knowledge. Compared to other subpopulations, the respondents' health-promoting lifestyle levels in this study were low, associated with ethnicity, education status, and health monitoring activities. The findings provided insight into the interaction between NHP knowledge and occupational status, which is associated with a higher health-promoting lifestyle level. Accordingly, the future health-promoting lifestyle intervention programmes in healthcare delivery should target these factors.

Efficacy, immunogenicity and safety of CoronaVac® in children and adolescents aged 6 months to 17 years: a multicenter, randomized, double-blind, placebo-controlled phase III clinical trial.

Safe and effective vaccines against COVID-19 for children and adolescents are needed. This international multicenter, randomized, double-blind, placebo-controlled, phase III clinical trial assessed the efficacy, immunogenicity, and safety of CoronaVac® in children and adolescents (NCT04992260). The study was carried out in Chile, South Africa, Malaysia, and the Philippines. The enrollment ran from September 10, 2021 to March 25, 2022. For efficacy assessment, the median follow-up duration from 14 days after the second dose was 169 days. A total of 11,349 subjects were enrolled. Two 3-µg injections of CoronaVac® or placebo were given 28 days apart. The primary endpoint was the efficacy of the CoronaVac®. The secondary endpoints were the immunogenicity and safety. The vaccine efficacy was 21.02% (95% CI: 1.65, 36.67). The level of neutralizing antibody in the vaccine group was significantly higher than that in the placebo group (GMT: 390.80 vs. 62.20, P <0.0001). Most adverse reactions were mild or moderate. All the severe adverse events were determined to be unrelated to the investigational products. In conclusion, in the Omicron-dominate period, a two-dose schedule of 3 µg CoronaVac® was found to be safe and immunogenic, and showed potential against symptomatic COVID-19 in healthy children and adolescents.

Evaluating quasi-experimental approaches for estimating epidemiological efficacy of non-randomised field trials: applications in Wolbachia interventions for dengue.

BACKGROUND: Wolbachia symbiosis in Aedes aegypti is an emerging biocontrol measure against dengue. However, assessing its real-world efficacy is challenging due to the non-randomised, field-based nature of most intervention studies. This research re-evaluates the spatial-temporal impact of Wolbachia interventions on dengue incidence using a large battery of quasi-experimental methods and assesses each method's validity. METHODS: A systematic search for Wolbachia intervention data was conducted via PUBMED. Efficacy was reassessed using commonly-used quasi-experimental approaches with extensive robustness checks, including geospatial placebo tests and a simulation study. Intervention efficacies across multiple study sites were computed using high-resolution aggregations to examine heterogeneities across sites and study periods. We further designed a stochastic simulation framework to assess the methods' ability to estimate intervention efficacies (IE). RESULTS: Wolbachia interventions in Singapore, Malaysia, and Brazil significantly decreased dengue incidence, with reductions ranging from 48.17% to 69.19%. IEs varied with location and duration. Malaysia showed increasing efficacy over time, while Brazil exhibited initial success with subsequent decline, hinting at operational challenges. Singapore's strategy was highly effective despite partial saturation. Simulations identified Synthetic Control Methods (SCM) and its variant, count Synthetic Control Method (cSCM), as superior in precision, with the smallest percentage errors in efficacy estimation. These methods also demonstrated robustness in placebo tests. CONCLUSIONS: Wolbachia interventions exhibit consistent protective effects against dengue. SCM and cSCM provided the most precise and robust estimates of IEs, validated across simulated and real-world settings.

A retrospective analysis of e-prescriptions for non-communicable diseases on a telehealth platform in Malaysia.

BACKGROUND: The management of non-communicable diseases (NCDs) has benefited from telehealth services. As these services which include teleconsultation services and e-prescriptions are relatively new in Malaysia, the data generated provide an unprecedented opportunity to study medication use patterns for the management of NCDs in the country. We analyze e-prescriptions from a local telehealth service to identify medication use patterns and potential areas to optimize medication use in relation to clinical practice guidelines. METHODS: A cross sectional observational study was conducted by retrieving e-prescription records retrospectively from a telehealth service. 739,482 records from January 2019 to December 2021 were extracted using a designated data collection form. Data cleaning, standardization and data analysis were performed using Python version 3.11. The diagnoses were classified according to the International Classification of Disease 10 (ICD-10), while medications were classified using the Anatomical Therapeutic Chemical (ATC) system. Diagnoses, frequency of use for medication classes and individual medications were analyzed and compared to clinical practice guidelines. RESULTS: The top five NCD diagnoses utilized by the service were hypertension (37.7%), diabetes mellitus (25.1%), ischemic heart disease (24.3%), asthma (14.4%), and dyslipidemia (11.7%). Medications were prescribed mostly in accordance with guideline recommendations. However, angiotensin receptor blockers (ARBs) were significantly more frequently prescribed compared to angiotensin converting enzyme inhibitors (ACEIs). Several medication classes appeared underutilized, including ACEIs in hypertensive patients with diabetes or ischemic heart disease, sodium glucose cotransporter 2 inhibitors in diabetic patients with ischemic heart disease, and metformin in patients with diabetes. CONCLUSIONS: Telehealth services are currently being utilized for the management of NCDs. Medication use for the management of NCDs through these services are mostly in accordance with guideline recommendations, but there exist areas that would warrant further investigation to ensure optimal clinical and economic outcomes are achieved.

Short-term associations of PM10 attributed to biomass burning with respiratory and cardiovascular hospital admissions in Peninsular Malaysia.

BACKGROUND: Biomass burning (BB) is a major source of air pollution and particulate matter (PM) in Southeast Asia. However, the health effects of PM smaller than 10 µm (PM10) originating from BB may differ from those of other sources. This study aimed to estimate the short-term association of PM10 from BB with respiratory and cardiovascular hospital admissions in Peninsular Malaysia, a region often exposed to BB events. METHODS: We obtained and analyzed daily data on hospital admissions, PM10 levels and BB days from five districts from 2005 to 2015. We identified BB days by evaluating the BB hotspots and backward wind trajectories. We estimated PM10 attributable to BB from the excess of the moving average of PM10 during days without BB hotspots. We fitted time-series quasi-Poisson regression models for each district and pooled them using meta-analyses. We adjusted for potential confounders and examined the lagged effects up to 3 days, and potential effect modification by age and sex. RESULTS: We analyzed 210 960 respiratory and 178 952 cardiovascular admissions. Almost 50% of days were identified as BB days, with a mean PM10 level of 53.1 µg/m3 during BB days and 40.1 µg/m3 during normal days. A 10 µg/m3 increment in PM10 from BB was associated with a 0.44% (95% CI: 0.06, 0.82%) increase in respiratory admissions at lag 0-1, with a stronger association in adults aged 15-64 years and females. We did not see any significant associations for cardiovascular admissions. CONCLUSIONS: Our findings suggest that short-term exposure to PM10 from BB increased the risk of respiratory hospitalizations in Peninsular Malaysia.

Central corneal thickness and topographic indices in Malaysian children with vernal keratoconjunctivitis.

INTRODUCTION: Vernal keratoconjunctivitis (VKC) is a chronic allergic disease characterised by intense ocular surface symptoms and corneal involvement. There is limited data about the corneal changes in children with VKC based on severity of the disease. We aimed to compare the central corneal thickness (CCT) and corneal topographic indices in Malaysian children with VKC, as well as among the varying grades of VKC severity. MATERIALS AND METHODS: This study is a comparative, crosssectional and hospital-based study. We recruited 83 children with VKC and 83 healthy children as controls. All children underwent complete ocular examinations, CCT measurement using an ultrasound pachymeter and corneal topography using a Placido disc corneal analyser. RESULTS: There was a statistically significant difference of means CCT and topographic indices in children with VKC compared to controls (p<0.05). The probability keratoconus reached 18% in children with VKC. The mean CCT was observed to be thinnest in the severe-to-very severe groups of VKC compared to the mild-to-moderate (p<0.05). The means simulated-K1 and -K2, apical keratometry, apical gradient curvature, superior-inferior index and keratoconus prediction index were significantly different in severe-tovery severe VKC compared to mild-to-moderate VKC and controls (p<0.05). However, there was no significant difference in mean cylinder value and percent probability keratoconus when comparing different groups of severity of VKC (p=0.912 and 0.070 respectively). CONCLUSION: Children with VKC have thinner CCT and topographic indices changes compared to healthy children. Similar pattern was observed between groups with VKC. Degree of astigmatism and probability of keratoconus were similar in mild-to-moderate and severe-to-very severe groups.

Evaluation of the retention of knowledge, skills and competency of post-neonatal resuscitation training among house officers.

INTRODUCTION: The Neonatal Resuscitation Programme (NRP) was first introduced in Malaysia in 1996 to train doctors and nurses working in paediatrics and obstetrics departments who are involved with the care of newborns soon after delivery. Prompt and effective neonatal resuscitation has been documented to reduce mortality and neonatal asphyxia. The programme has been revised every five years and is now in the 8th edition. NRP training was made into a key performance indicator (KPI) by the Ministry of Health in 2016 for all house officers to be trained in this programme during their 2-year posting and this is usually conducted during the paediatric posting. This study aims to evaluate the retention of their knowledge, skills and competency at 3, 6, and 9 months after the initial NRP training. MATERIALS AND METHODS: A total of 34 house officers were enrolled in the study on joining the paediatric unit of Hospital Kulim. They were given the "Textbook of NRP" to prepare for the theory paper that consisted of 30 multiplechoice questions (MCQs). Two to four weeks later they went through a day of training on the resuscitation of the newborn using low-fidelity simulation manikins. They were taught to recognise a newborn who needed resuscitation after delivery, prepared the equipment for resuscitation and learned the skills of resuscitation. The skills included the initial steps, bag valve mask ventilation, intubation, cardiac massage, umbilical vein cannulation and use of medications. They were also taught the performance of objective structured clinical examination (OSCE) A and B. They were evaluated at 3, 6, and 9 months after the completion of their training using the MCQs and the performance checklist in the NRP textbook. RESULTS: The results showed that there was a significant reduction in their knowledge retention as shown by their performance in multiple choice questions. Similarly, there was a significant loss of competency in their skills and competency in resuscitation using bag mask ventilation, intubation and performance of OSCE A and OSCE B. However, their performance at initial steps showed no significant reduction. CONCLUSION: In view of the observed deterioration a refresher course in NRP before transferring out to the districts is recommended to improve their overall performance.

A clinical audit on the diagnosis and management of infective endocarditis in a tertiary heart centre in Malaysia.

INTRODUCTION: Infective endocarditis (IE) has a high mortality rate in developing countries including Malaysia. This clinical audit aims to identify the shortcomings in the diagnosis and management of IE patients in a local tertiary centre to implement changes for improvement. MATERIALS AND METHODS: This retrospective audit had two cycles - the first includes all IE patients in Sarawak Heart Centre, Malaysia from January 2020 to December 2022 with different parameters (blood culture, echocardiogram, the appropriateness of antibiotics and surgery) assessed against Malaysian Clinical Practice Guideline (CPG); and reaudit from July 2023 to December 2023. Interventions before re-audit include presentation at different hospital levels and continuing medical education. RESULTS: Fifty patients were recruited (37 in the first cycle, 13 in the second cycle). The median age was 48.5 years with male predominance. Valve prosthesis (12.0%) and rheumatic heart disease (10.0%) were the commonest predisposing factors. Native mitral (44.0%) and aortic valves (28.0%) were most commonly involved. Twenty-eight (56.0%) patients were culture-positive. In the first cycle, most parameters (culture technique 0.0%, vegetation measured 54.1%, empirical 5.4%, culture-guided 29.7% antibiotics therapy, indicated surgery 0.0%) did not achieve the expected standard except timeliness of echocardiograms and blood culture incubation period. After initial interventions, all parameters showed statistically significant improvement (culture technique p<0.001, echocardiography p<0.001, empirical p<0.001, culture-guided p=0.021, surgery p<0.001) during the re-audit. CONCLUSION: Compliance with clinical practice guidelines (CPG) on IE management was suboptimal during the first audit but improved after interventions. Hence, regular continuing medical education (CME) is essential, and a written hospital protocol may be useful. Regular audits alongside multidisciplinary teamwork are crucial efforts.

Perceptions of climate change and associated health impacts among communities in Johor River Basin, Malaysia.

INTRODUCTION: As climate change is threatening every region of the world, extreme weather events resultant of global warming is occurring at increasing rate and scale in Malaysia. Weather-related disasters such as flood and haze pose critical challenges to the infrastructure and raise public health concerns in the country, especially when main economic sectors rely heavily on climate variability. Public perception on environmental issues is crucial for development of pro-environmental policies. Among studies conducted to understand public awareness regarding global warming, reports of perception on the health impacts were very limited. Taking this limitation into account, this study was designed to examine the perception on the health impacts of climate change among the diverse communities living in the Johor River Basin. MATERIALS AND METHODS: The cross-sectional study was conducted through cloud-data-based digital questionnaires completed by randomly selected residents in the Johor River Basin (n=647). Data was analysed with descriptive statistics using SPSS 27 (IBM®) Software. Comparisons between indigenous and non-indigenous communities were performed using Chi square analysis. RESULTS: Respondents in this study consisted of indigenous people (n=79) and non-indigenous people (n=568). Indigenous respondents generally perceived more frequent occurrence of extreme weather events in the next 20 years, even for the phenomena unfamiliar in Malaysian settings. All respondents showed similar concerns for health impacts of global warming, although the non-indigenous respondents perceived the risk further into the future (25 years) compared to the indigenous respondents who perceived current or imminent (<10 years) risks. Intense concerns for self, children, family members and community were shown by nearly all indigenous respondents (97-99%), while the non-indigenous people in this study expressed stronger concerns at country level and for future generations. During the last haze episode, most indigenous respondents (85%) did not notice any change in air quality nor discomfort among family members, in contrast 70% of the nonindigenous respondents claimed to have suffered from breathing problems themselves as well as others in the family. All respondents were concerned about air quality in their surroundings, indigenous people were concerned for the near future (<10 years), and non-indigenous people were concerned for the next 25 years. CONCLUSION: In this study, respondents were generally concerned about the health impacts of unimpeded global warming. There was significant difference in perceptions between indigenous and non-indigenous respondents. The findings were useful, complemented with further studies, to improve understanding of public awareness and to help develop relevant education programmes accessible for wider audience.

Stunting and its association with feeding problem among under five children: a case-control study in Kuantan district, Malaysia.

INTRODUCTION: Stunting is the most prevalent form of malnutrition among infants and young children population, both globally and locally. It refers to low height-for-age children and is primarily caused by chronic under nutrition. The objective of this study is to determine the association between stunting and feeding problems and to explore the risk factors for stunting among children aged 6 to 59 months attending health clinics in the Kuantan district. MATERIALS AND METHODS: A case-control study involving 160 children that attended six health clinics in Kuantan from August to October 2021 with a ratio of 1 case: 3 controls. Data were collected from mothers using a questionnaire consisting of sociodemographic and feeding assessment adapted from a validated World Health Organization (WHO) integrated management of childhood illness (IMCI) assessment form. The data was analysed using IBM SPSS version 26.0. Binary logistic regression analysis was used to identify factors associated with stunting. The odds ratio was used to measure the strength of the association between outcome and predictor variables. The significance value was set at p<0.05. RESULTS: Children with identified feeding problems have more than four-time significantly higher risk of becoming stunted (Odds Ratios, OR: 4.2; 95% Confidence Intervals, 95%CI: 1.4, 12.8) as compared to children with no feeding problems. Specifically, children with inadequacy in feeding components; amount, variety and frequency of meal each have significantly six-time higher risk (OR: 6.2; 95%CI: 2.7, 14.5), four-time higher risk (OR: 4.2; 95%CI: 1.4, 12.3), and three-time higher risk (OR: 2.8; 95%CI: 1.1, 6.9), of becoming stunted as compared to children with adequate feeding. Additionally, with a decrease of one week in delivery week, one kilogram in birth weight and one centimetre in maternal height, there is a respectively significant 40.0% (OR: 0.6; 95%CI: 0.4, 0.9), 80.0% (OR: 0.2; 95%CI: 0.1, 0.7) and 11.0% (OR: 0.89; 95%CI: 0.82, 0.98) increase in the risk of become stunted among children. CONCLUSION: Feeding problems specifically inadequate food amount, food variety and meal frequency not following the recommendation contribute to stunting in young children. Other factors identified are lower maternal height and children with lower birth weight and delivery week. This highlights the need for more excellent detection and intervention of nutritional concerns and risk factors to prevent stunting.

Translation and validation study of obstructive sleep apnoea (OSA-18) questionnaire into Bahasa Malaysia (MALAY OSA-18).

INTRODUCTION: According to the American Academy of Sleep Medicine, obstructive sleep apnoea (OSA) is sleep-related breathing disorder that involves a decrease or complete halt in airflow despite an ongoing effort to breathe. The OSA-18 questionnaire is a short and self-administered questionnaire to assess paediatric patients' symptoms and quality of life with obstructive sleep apnoea. MATERIALS AND METHODS: This cross-sectional study is conducted at the Otorhinolaryngology-Head and Neck Surgery (ORL-HNS) clinic of Hospital Universiti Sains Malaysia. The forward and backward translation of the OSA- 18 questionnaire into the Malay language (Malay OSA-18) was performed and tested for content and face validity. The questionnaire's internal validity and reliability were tested using Pearson's correlation, Cronbach α and inter-reliability coefficient tests. The psychometric properties (validity, reliability and reproducibility) were assessed. RESULTS: We observed 84 patients ranging from six months up to 12 years of age. The mean age was 8 years old, and 63.1% were male patients. Among the samples, 96.4% presented with palatine tonsillar enlargement, and 84.5% presented with adenoid tonsillar enlargement. Based on the questionnaire the patient's caregiver answered, Pearson's correlation demonstrated that all the symptom scales correlate and measure the same things. The Cronbach's α coefficient value for each symptom scale was acceptable, within 0.6-0.8. The total Cronbach's α coefficient value was 0.89. The test-retest evaluation was excellent, with the value of intraclass correlation (ICC) more than 0.90. CONCLUSION: The Malay version of the OSA-18 questionnaire is equivalent to the original English version. It is an effective tool to assess the paediatric OSA patient's symptoms and quality of life based on the obtained validity, reliability and reproducibility values. Therefore, it is recommended to be a screening tool in daily practice.

Oral health assessment of epilepsy patients from a tertiary hospital in Asia.

INTRODUCTION: Oral health problems are frequently overlooked in patients with epilepsy. We evaluate the oral health status of epilepsy patients from a tertiary teaching hospital. MATERIALS AND METHODS: We conducted a cross-sectional study of epilepsy patients from the neurology clinic, Hospital Canselor Tuanku Muhriz, Kuala Lumpur. The dental assessment included the decayed, missing and filled teeth (DMFT) criteria, as well as the plaque and periodontal status by dentists. RESULTS: A total of 151 patients were recruited. The median age of onset of epilepsy was 16 (IQR 7-30) years, with generalised seizures at 59.6% and focal seizures in 40.4% of patients. Fair or poor oral health was present in 59 (39.1%) and gingivitis was seen in 65 (43%). The median DMFT decayed (D), missing (M) and filled teeth (FT) was 3 (IQR 1- 7). The median age of patients with fair or poor oral health was older (40 years, IQR 31-51) than the patients with excellent or good oral health (33 years, IQR 26-45), (p=0.014). Multivariate logistic regression analysis showed that carbamazepine (Odds Ratios, OR: 3.694; 95% Confidence Intervals, 95%CI: 1.314, 10.384) and hypertension (OR 6.484; 95%CI: 1.011, 41.594) are the risk factors for fair or poor oral health. Phenytoin use is 4.271 times more likely to develop gingivitis (OR 4.271; 95% CI: 1.252, 14.573). CONCLUSION: Factors that contribute to fair or poor oral health include age, antiseizure medications like phenytoin and carbamazepine, and hypertension. Effective preventive strategies should be implemented to maintain oral health in epilepsy patients.

Two-year retrospective review of lens-induced glaucoma in Hospital Taiping, Perak, Malaysia.

INTRODUCTION: Delayed cataract surgery has long been known to cause lens-induced glaucoma (LIG). This study examined the demographic and clinical profile, ocular characteristics and outcomes of LIG in a tertiary referral centre in Malaysia. MATERIALS AND METHODS: Data from the National Eye Database (Malaysia) for cataract surgery performed at Hospital Taiping, Perak, between January 2019 and December 2020 were reviewed. The medical records of patients with LIG were retrieved to obtain demographic data, clinical profiles and visual outcomes. RESULTS: Of 3233 patients who underwent cataract surgery at Hospital Taiping, Perak, between 2019 and 2020, 25 underwent emergency surgery for LIG. However, only 24 patients fulfilling the diagnostic criteria for LIG were included in the study: 14 (58.33%) patients with phacomorphic and 10 (41.6%) patients with phacolytic glaucoma. The mean age of the patients was 66±12 years. Women and men were equally affected. Most patients were Malay (75%), followed by Chinese (16.67%) and Indian (8.33%). The anterior chamber depth (ACD) was significantly shallow with a mean value of 2.72 mm. Nineteen (79.1%) patients presented with visual acuity of worse than counting fingers. The mean intraocular pressure (IOP) at presentation was 47.5±13.66mmHg, which improved to 15.08±8.09mmHg postoperatively. A best-corrected visual acuity of 6/15 and better was achieved in 20 patients (83.33%) despite glaucomatous optic neuropathy being present in 41.67% of the cases. The majority (58.3%) of surgeries were performed via extracapsular cataract extraction, while six (25%) of our patients underwent successful phacoemulsification. Seven (29.17%) patients had intraocular complications: five with zonular dialysis and two with posterior capsule rupture. Of these seven cases, four ended up with intracapsular cataract extraction, leaving two of them aphakic. CONCLUSION: Prompt cataract surgery is paramount in all LIG cases to reduce IOP and achieve better visual outcomes. Despite the promising prognosis associated with early surgical intervention, patients should be counselled about the potential for a guarded visual prognosis from complicated surgery and its long-term complications.

Association between serum uric acid levels with essential hypertension and its metabolic variables in Hospital Universiti Sains Malaysia.

INTRODUCTION: Hyperuricaemia is common in essential hypertension with varying results in different populations. This study sought to ascertain the association between serum uric acid levels and essential hypertension in Hospital Universiti Sains Malaysia (HUSM). MATERIALS AND METHODS: A case-control study design involving 132 subjects (88 subjects of hypertension patients for case group and 44 subjects for control group) aged 18 to 40 years old of both genders was conducted at HUSM primary care clinic and physician clinic from May 2020 to May 2021. Blood samples were collected from each of the case and control subjects and analysed for serum uric acid, urea, creatinine, total cholesterol, triglycerides, LDL and HDL on chemical analyser Architect c8000. The data were analysed by using SPSS Statistics 26.0 version. RESULTS: The proportion of subjects with hyperuricaemia in the case group was 48.9%. A significant difference in the uric acid levels between the case group (390.64±92.65µmol/L) and control group (352.09±86.07µmol/L), (p<0.05) was observed. There was no significant difference in the serum uric acid mean ± SD based on the duration of hypertension (<5 years and ≥5 years), (p=0.331) and stages of hypertension (p>0.05). In case group, significant correlations were established between uric acid and triglycerides (r=0.255, p<0.05), uric acid and HDL (r= -0.223, p<0.05), uric acid and urea (r=0.299, p<0.05), uric acid and creatinine (r=0.486, p<0.01). No correlation among uric acid and total cholesterol levels (p>0.05), uric acid and LDL (p>0.05). Serum uric acid was a vital variable in developing hypertension (p<0.05) but not when adapted for age and body mass index (BMI) (p>0.05). CONCLUSION: Serum uric acid was significantly elevated in essential hypertension. The significant associations were established between uric acid and triglycerides, HDL, urea and creatinine in essential hypertension. Serum uric acid was a vital variable to develop hypertension, but the association was weakened by other co-founders as age and BMI. A large-scale population-based study is required to truly conclude the association between serum uric acid levels and essential hypertension in our population.

Assessing informal caregiver burden as well as knowledge on positioning and feeding of stroke patients in a tertiary hospital in Kelantan, Malaysia.

A significant proportion of stroke patients in Malaysia are supported by informal caregivers who often lack sufficient training. This lack of preparation contributes to an escalation in caregiver burden. A cross-sectional study was conducted using Caregiving Knowledge Questionnaire (CKQ-my) and Zarit Burden Interview (ZBI) with convenient sampling. The findings revealed that caregivers had limited knowledge regarding proper positioning, and most of them reported experiencing mild burden. Multiple logistic regression analysis showed that informal caregivers who were also the primary caregivers for severe stroke patients experienced a higher burden. Recognising and understanding the factors that contribute to caregiver burden in stroke cases is essential for developing effective programs to improve the quality of life for both stroke survivors and their informal caregivers.

Identifying postoperative cognitive dysfunction after elective coronary artery bypass graft surgery in a tertiary centre in Malaysia.

Postoperative cognitive dysfunction (POCD) is a significant concern, with incidences reported up to 70% following cardiac surgery. Therefore, we aim to evaluate the incidence of POCD after elective coronary artery bypass graft (CABG) surgery at our single centre over a one-year period from August 2021 to July 2022. We included 34 patients in the study and conducted serial cognitive assessments up to three months post-surgery. Interestingly, our findings indicated an absence of POCD among patients who underwent elective CABG. Reasons contributing to this outcome are multifactorial, which may include the patients' younger age, higher educational levels, lack of pre-existing neurological disorders, meticulous intraoperative cerebral saturation monitoring, and the duration of aortic crossclamp and cardiopulmonary bypass time.

Obtaining assent for research involving children in Malaysia: a position statement from the Academy of Medicine of Malaysia College of Paediatrics.

The Academy of Medicine of Malaysia College of Paediatrics acknowledges the role of children in research and this position statement explores the ethical considerations in obtaining assent from minors in the Malaysian context. It highlights the importance in respecting children's agency and navigating cultural complexities. The College proposes flexibility in the minimum age for assent of at least nine years old, while emphasising the need for a tailored assent procedure. Addressing language and cultural diversities and expanding local empirical research on a formal assent process are some building blocks in developing a standardised nationwide process in obtaining assent from children.
