The worldwide upsurge of Type 2 Diabetes Mellitus (T2DM) warrants the attention of public health, especially in complications. Diabetic Retinopathy (DR), the commonest ocular complication, contributes to the growing incidence of blindness. Recommendations that the visual acuity (VA) assessment guidelines should be used in DR screening was not routinely practiced. This study aims to model the predictive effect of VA - a simple economic clinical assessment - upon DR in patients with T2DM. A case-control study was conducted in Hospital Universiti Sains Malaysia with subjects recruited from the ophthalmology clinic. The primary variable during analysis was VA, and the outcome variable was DR. Models with eight control variables which included age, gender, and duration of DM were developed. The predictive effect measured by logistic regression showed that when unadjusted; four variables had a significant association with DR, at p-value<0.25; they were the duration of DM, systolic blood pressure, glycosylated haemoglobin and VA. From the eight different predictive models, the estimated adjusted odds ratio produced ranges from 6.09 to 11.64. Our study shows that VA has a predictive effect upon DR in T2DM patients. We suggest VA assessment, to be on par with the monitoring of blood pressure and blood glucose.

The purpose of this study was to determine the sawmill workers’ knowledge, attitude and practice (KAP) in relation to noise-induced hearing loss (NIHL). A cross-sectional study was conducted involving 83 workers from 3 factories in Kota Bharu, Kelantan. Questionnaires were distributed to obtain the socio-demography, knowledge, attitude and practice level in relation to noise-induced hearing loss (NIHL). The weak areas identified in the knowledge section were treatment aspects (15.5%), signs and symptoms of NIHL (20.2%) and risk factors (31%). As for attitude; the prevention aspects were the lowest (25.3%), followed by risk taking attitude (26.2%), and causes of hearing loss (42.1%). Overall, the practice was not encouraging at all. It is important to have an education program to raise workers’ awareness and to improve their attitude and practices towards noise-induced hearing loss.

Background: Traumatic brain injury (TBI) has been associated with an acute stress response mediated by the sympathoadrenomedullary axis, which can be assessed by measuring blood glucose level. Methods: This prospective observational study was conducted for a year in 2007 among 294 patients who had been treated for TBI in Hospital Kuala Lumpur. Patients fulfilling the set criteria were recruited into the study and data, including blood glucose level and Glasgow Outcome Score at 3-month follow-up, were collected. Results: 294 patients were included in the study: 50 females (17.0%) and 244 males (83.0%). The majority of cases were young adult patients (mean age of 34.2 years, SD 13.0). The mean blood glucose level during admission and post-surgery were 6.26 mmol/L (SD 1.30, n = 294) and 6.66 mmol/L (SD 1.44, n = 261), respectively. Specifically, the mean admission glucose level associated with mild TBI was 5.04 mmol/L (SD 0.71); moderate TBI, 5.78 mmol/L (SD 1.02); and severe TBI, 7.04 mmol/L (SD 1.18). The mean admission glucose level associated with a poor outcome in patients with isolated TBI was 6.98 mmol/L (SD 1.21). Patients with admission glucose of 5.56 mmol/L (SD 1.21) were more likely to have a favourable outcome. Conclusion: Mild, moderate, and severe TBI were associated with an increase in blood glucose levels during admission, and the mean increase in glucose levels is based on the severity of the isolated TBI. Surgical intervention did not cause further significant changes in blood glucose levels. Patients with isolated TBI and minimal increases in blood glucose levels were more likely to have a favourable outcome.

Renal replacement therapy in Malaysia has changed dramatically. In 1980 there were only 59 patients on dialysis. Since then the number of patients has increased exponentially from 4,540 in 1998 to almost 15,000 in 20061. Autogenous Arteriovenous Fistula (AVF) provides an excellent long term hemodialysis access with low rates of infection, thrombosis and is cost effective. Hospital Sultanah Bahiyah is a tertiary hospital situated in the northern region of Peninsular Malaysia. Vascular Access creation is one of the main services provided by our surgical unit; with an average of 100 patients seen in the vascular access clinic per month. The number of AVF operations has increased from 30 cases in 2001 to 328 in 2007. The reported rates of Primary Fistula Failure (fistula fail to mature) varies from 8% to 53%2,4. Immature fistulae will lead to prolonged dependence on dialysis catheters. This phenomenon is well known to be associated with the risk of infective complications, central venous thrombosis or stenosis and patients’ inconvenience. Numerous studies have reported the predictors of successful fistulae, but are varied in their design, definitions, end points and clinical factors considered 2,3 Preoperative imaging also has been proposed, but their widespread use is generally limited in most of the centres4. Knowing the risk factors for failure will help the surgeon to take the necessary precautions and preventive measures more effectively. The information may help to stratify the patients into various risk groups based on their likelihood to develop fistula failure. Thus, the main objective of this study was to identify clinical risk factors that are related to Failure to Mature (FTM) of autogenous AVF.

Purpose: We compared the patency and the suitability of arteriovenous fistula (AVF) created for vascular access by two approaches: (a) physical examination with preoperative vascular mapping and (b) physical examination alone. Methods: We compared the patency and the suitability of AVF created in patients for dialysis. There were two cohorts of patients of 79 patients each: (a) patients with AVF created based on the combination of physical examination and preoperative vascular mapping (PE+VM) and (b) patients with AVF created based on physical examination (PE) alone. Fistula patency is defined as clinical detection of thrill (or auscultation) of murmur over the fistula and coded as having thrills (patent) versus not having thrills (not patent). Suitability of fistula is defined as functioning AVF (AVF can be adequately used via 2-needle cannulation for dialysis) and coded as suitable versus not suitable. Results: AVF created after the preoperative vascular mapping (PE+VM) has 5.70 (at six weeks) and 3.76 (at three months) times higher chance for patency, and 3.08 times higher chance for suitable AVF for dialysis than AVF created after the physical examination (PE) alone. Conclusion: Physical examination with preoperative ultrasound mapping (PE+VM) significantly improves the short term patency and the suitability of AVF for dialysis.

Objective: Many studies have emphasized the significance of verbal memory for the functional outcome in schizophrenia. A preserved capability to encode and recall verbal information is essential for the long-term efficacy of psychoeducational programs and other psychological intervention to ensure the successful transfer of newly acquired skills or knowledge into everyday life. Aims of this study aimed to validate the MVALT among schizophrenia patients in HUSM. Methods: The subjects were 15 schizophrenia patients conveniently selected from the patients that attended follow up at the psychiatry clinic in HUSM or inpatients who have been admitted during the study period and 15 healthy control subjects as a comparison. Reliability and validity of the MVAVLT were analyzed. Results: The validation study showed that the Malay version Auditory Verbal Learning Test (MVAVLT) had a good validity (factor analysis 0.66 to 0.98) and test-retest reliability (pearson correlation ranged from 0.24 to 0.84) and has been shown to be sensitive in discriminating between normal and schizophrenia patients. In line with the previous research, the schizophrenia patients performed significantly worse than healthy control in all indexes measured in MVAVLT. Conclusion: The screening of deficits in verbal learning and memory among the schizophrenia patients is important, for early detection and treatment since it can be helpful for clinicians and psychologists in their counseling sessions. Subsequently, it helps patients to reduce such cognitive difficulties and their impact by using specific rehabilitation with the usage of newer antipsychotic agents.

A prospective cohort study was done to evaluate the role of surgery in patients with spontaneous supratentorial intracerebral haemorrhage (SICH) and to identify predictors of outcome including the use of invasive regional cortical cerebral blood flow (rCoBF) and microdialysis. Surgery consisted of craniotomy or decompressive craniectomy. The ventriculostomy for intracranial pressure (ICP) monitoring and drainage and regional cortical cerebral blood flow (rCoBF) and microdialysis were performed in all subjects. Pre and post operative information on subjects were collected. The study end points was functional outcome at 6 months based on a dichotomised Glasgow Outcome Scale (GOS).The selected clinical, radiological, biochemical and treatment factors that may influence the functional outcome were analysed for their significance. A total of 36 patients were recruited with 27(75%) patients had Glasgow Coma Score (GCS) between 5 to 8 on admission and 9(25%) were admitted with GCS of 9. At 6 months, 86 % had a poor or unfavourable outcome (GOS I-III) and 14% had good or favourable outcome (GOS IV-V). The mortality rate at 6 months was 55%. Univariate analysis for the functional outcome identified 2 significant variables, the midline shift (p=0.013) and mean lactate:pyruvate ratio (p=0.038). Multivariate analysis identified midline shift as the single significant independent predictor of functional outcome (p=0.013).Despite aggressive regional cortical cerebral blood flow (rCoBF) and microdialysis study for detection of early ischemia, surgical treatment for spontaneous intracerebral haemorrhage only benefited a small number of patients in terms of favourable outcome (14%) and in the majority of patients (86%), the outcome was unfavourable. Patients with midline shift > 5mm has almost 21 times higher chances (adj) OR 20.8 of being associated with poor outcome (GOS I-III).

Objectives: Dengue remains hyperendemic in Malaysia despite extensive vector control activities. With dynamic changes in land use, urbanisation and population movement, periodic updates on dengue transmission patterns are crucial to ensure the implementation of effective control strategies. We sought to assess shifts in the trends and spatial patterns of dengue in Kelantan, a north-eastern state of Malaysia (5°15’N 102°0’E). Methods: This study incorporated data from the national dengue monitoring system (eDengue system). Confirmed dengue cases registered in Kelantan with disease onset between January 1, 2016 and December 31, 2018 were included in the study. Yearly changes in dengue incidence were mapped by using ArcGIS. Hotspot analysis was performed using Getis-Ord Gi to track changes in the trends of dengue spatial clustering. Results: A total of 10 645 dengue cases were recorded in Kelantan between 2016 and 2018, with an average of 10 dengue cases reported daily (standard deviation, 11.02). Areas with persistently high dengue incidence were seen mainly in the coastal region for the 3-year period. However, the hotspots shifted over time with a gradual dispersion of hotspots to their adjacent districts. Conclusions A notable shift in the spatial patterns of dengue was observed. We were able to glimpse the shift of dengue from an urban to peri-urban disease with the possible effect of a state-wide population movement that affects dengue transmission.

When the first report of COVID-19 appeared in December 2019 from Wuhan, China, the world unknowingly perceived this as another flu-like illness. Many were surprised at the extreme steps that China had subsequently taken to seal Wuhan from the rest of the world. However, by February 2020, the SARS-CoV-2 virus, which causes COVID-19, had spread so quickly across the globe that the World Health Organization officially declared COVID-19 a pandemic. COVID-19 is not the first pandemic the world has seen, so what makes it so unique in Malaysia, is discussed to avoid a future coronacoma.

Background: No previous study has assessed the impact of childhood disability on parents and family in the context of Malaysia, and no instrument to measure this impact has previously been available. The objective of this cross-sectional study was to determine the reliability of a Malay version of the PedsQL™ Family Impact Module that measures the impact of children with disabilities (CWD) on their parents and family in a Malaysian context. Methods: The study was conducted in 2009. The questionnaire was translated forward and backward before it was administered to 44 caregivers of CWD to determine the internal consistency reliability. The test for Cronbach’s alpha was performed. Results: The internal consistency reliability was good. The Cronbach’s alpha for all domains was above 0.7, ranging from 0.73 to 0.895. Conclusion: The Malay version of the PedsQL™ Family Impact Module showed evidence of good internal consistency reliability. However, future studies with a larger sample size are necessary before the module can be recommended as a tool to measure the impact of disability on Malay-speaking Malaysian families.
