The effect of job demands on health and work outcomes: A longitudinal study among Malaysian employees

Muhamad Nasharudin NA, Idris MA, Young LM

Psych J, 2020 Oct;9(5):691-706.
PMID: 32755003 DOI: 10.1002/pchj.378

The purpose of the current study was to investigate the impact of job demands on health and work outcomes among Malaysian workers. We hypothesized that job demands (i.e., emotional demands and physical demands) would predict future work-related burnout and work engagement, in turn affecting sleep problems and job performance (in-role, extra-role). A longitudinal two-wave survey was conducted among Malaysian workers and valid data from 345 participants were analyzed using structural equation modeling. The results revealed that work-related burnout predicts sleep problems while work engagement increased employees' job performance over time. Overall, the current study highlights the importance of specific job demands (i.e., emotional demands and physical demands) that specifically affect health-related behavior and work-related behavior among workers.
Bilateral central retinal vein occlusion in a pregnant lady

Loh MA, Abirami S, Chong MF

Med J Malaysia, 2017 04;72(2):130-132.
PMID: 28473680 MyJurnal

We report a rare case of central retinal vein occlusion (CRVO) in pregnancy. There was dramatic deterioration of vision in both eyes through pregnancy despite repeated attempts of laser treatment and systemically controlled diabetes. Significant improvement was noted postpartum. Pregnancy is an aggravated factor of bilateral CRVO.

Malaysia is confronted with an increasing incidence of HIV and AIDS among adolescents and young adults. The effectiveness of various programs offered to school going teenagers is unknown. The objective of this study is to measure the effectiveness of two hours talk on sex education offered by a non governmental organization (NGO) in improving youngsters' knowledge and perception towards HIV and AIDS. A cross sectional study was conducted among the adolescent students from a secondary school in Ipoh, Perak, a province of Malaysia. A total of 182 students participated in the study. A standard questionnaire consisting of demographic data, knowledge and perception towards HIV/ADIS were distributed before (pre-test) and after the intervention (post-test). Performance of participants was compared to establish the effectiveness of the intervention. Our findings suggests that there was a significant increase in participants' knowledge and perception after the intervention (p = 0.000). Knowledge improvement was found in both genders however, improvement in perception was higher among female students. Interestingly, 80% of participants disagree that sexual education will encourage sex among youngsters. NGOs are playing a supplementary role in providing sex education programs in schools. This program although of short duration but it is effective in enhancing adolescence awareness about HIV/AIDS.

There is a need for country/population-specific databases because the existence of population-specific mutations for single gene disorders is well documented, and there is also good evidence for ethnic differences in the frequencies of genetic variations involved in complex disorders. Thus the Singapore Human Mutation/Polymorphism Database (SHMPD) was created to provide clinicians and scientists access to a central genetic database for the Singapore population. The data catalogued in the database include mutations identified in Singapore for Mendelian diseases, and frequencies of polymorphisms that have been investigated in either healthy controls or samples associated with specific phenotypes. Data from journal articles identified by searches in PubMed and other online resources, and via personal communications with researchers were compiled and assembled into a single database. Genes are categorized alphabetically and are also searchable by name and disease. The information provided for each variant of the gene includes the protein encoded, phenotype association, gender, size, and ethnic origin of the sample, as well as the reported genotype and allele frequencies, and direct links to the corresponding abstracts on PubMed. Our database will facilitate molecular diagnosis of Mendelian disorders and improve study designs for complex traits. It will be useful not only for researchers in Singapore, but also for those in countries with similar ethnic backgrounds, such as China, Taiwan, Hong Kong, Indonesia, and Malaysia.
Fulltext Bilateral optic neuritis in a boy - More than the eyes

Loh MA, Alex Khoo PC, Chong MF

Med J Malaysia, 2016 04;71(2):79-80.
PMID: 27326949

Neuromyelitis optica (NMO) is a rare disorder in children with variable presentation. We report a 7-year-old boy who presented with bilateral retrobulbar optic neuritis and responded very well to treatment. He was also positive for aquaporin 4 (AQP4) antibodies, which is part of an emerging endophenotype within autoimmune neurological disorders in childhood.
Fulltext The Effectiveness of Conducting Home Visits by Medical Students among Malaysians with Type 2 Diabetes: A Retrospective Analysis

J ASEAN Fed Endocr Soc, 2019;34(1):56-61.
PMID: 33442137 DOI: 10.15605/jafes.034.01.09

Background: Medical students at the International Medical University (IMU), Seremban, Malaysia were required to assess patients at home over a period of two years as a part of their curriculum. The students conducted six visits to educate their patients and help them utilize available resources to manage their disease.This study aims to examine whether patients with diabetes visited improve their control of their disease, specifically in terms of their HbA1c measurement.
Methodology: We used a retrospective, matched before and after study design to prevent biased levels of effort by students conducting the home visits over two years. Information was obtained through reports written by IMU students. Convenient sampling was used to select outpatients undergoing treatment 'as usual' from a health clinic and were subsequently matched as controls.
Results: There was a significant decrease in the mean HbA1c among 57 patients with diabetes who were CFCS subjects [from 8.4% (68 mmol/mol) to 7.3% (57 mmol/mol) p<0.001], while the mean HbA1c levels among 107 matched control subjects rose significantly from 7.9% (63 mmol/mol) to 8.3% (67 mmol/mol) (p=0.019) over a similar period. The two groups were controlled for most biological and socioeconomic variables except for comorbidities, diabetic complications and medication dose changes between groups.
Conclusion: Behavioural intervention in the form of home visits conducted by medical students is an effective tool with a dual purpose, first as a student educational initiative, and second as a strategy to improve outcomes for patients with diabetes.
