PMID: 15272771

Job stress has now become one of the most significant health and safety issues in the workplace and one of the least understood areas of organizational cost. A cross-sectional study to assess job strain and dissatisfaction in lecturers of the School of Medical Sciences, Universiti Sains Malaysia (USM) was undertaken between August 2001 and May 2002. The original English version of the Job Content Questionnaire (JCQ) version 1.7 (revised 1997) by Robert Karasek was self-administered to 73 (response rate 58.4%) lecturers in School of Medical Sciences USM. The prevalence of job strain (defined by low decision latitude and high psychological demands) in USM was 23.3%. The risk factors of job strain in the lecturers were psychological stressors (adjusted OR 1.2, 95% CI 1.0, 1.4), created skill (adjusted OR 0.4, 95% CI 0.2, 0.8) and working in clinical-based departments (adjusted OR 18.7, 95% CI 1.6, 22.7). The prevalence of job dissatisfaction was 42.6%. Associated factors of job dissatisfaction in USM lecturers were decision authority (p < 0.001) and psychological job demand (p < 0.001). We conclude that psychological stressors and created skill were non-protective and protective, respectively, against job strain in USM lecturers. Clinical-based lecturers experienced higher job strain compared to non-clinical-based lecturers. Psychological job demand was strongly associated with job dissatisfaction, and decision authority was protective against job dissatisfaction.

Fulltext A study of locomotor disabilities in a Malay community in Kuala Selangor

Osman A, Rampal KG

Med J Malaysia, 1989 Mar;44(1):69-74.
PMID: 2533959

A study was conducted to determine the prevalence of locomotor disability in a Malay Community in Tanjung Karang, Kuala Selangor in 1984. The causes of these disabilities, the mobility and occupational handicaps they caused and the types of treatment received were determined. Fifty percent of the households in this area were selected by stratified random sampling and all persons above seven years of age were included in the sample. The prevalence of locomotor disability was 3.9%. The prevalence among males was 5.2% and among females 2.6%. The prevalence increased with age, being as low as 0.6% in the 7-14 year age group and as high as 20.5% in the above 55 year age group. The disabilities resulted mainly from trauma (49%) and musculoskeletal and neurological problems (46.9%). Ninety percent (44 cases) had difficulty only in performance of daily activity and 20 cases (40.8%) had no mobility handicap whatsoever. Forty two (85.7%) of the 49 cases had received treatment.

Chow SK, Yap DFS, Sim JH, Tan PS, Hee NKY, Teow XM, et al.

Med J Malaysia, 2023 Dec;78(7):907-913.
PMID: 38159927

INTRODUCTION: This study aimed to determine the prevalence and association between the severity of COVID-19 and short and long-term neuropsychiatric symptoms, as well as the risk factors for the development of these symptoms.
MATERIALS AND METHODS: A prospective observational study was conducted between 1st October 2021 till September 2022 in the state of Johor, Malaysia. 300 patients with confirmed SARS-CoV-2 infection were randomly selected and followed up for six months. Data were analysed by using Chi-square test, Fisher's Exact test, Paired t test and Multiple logistic regression.
RESULTS: The prevalence of short-term neuropsychiatric symptoms was 78%, with anosmia being the most prevalent symptom. Long-term symptoms were found in 22.75% of patients, with headache being the most prevalent (p= 0.001). COVID-19 Stage 2 and 3 infections were associated with a higher risk of short-term neuropsychiatric symptoms, OR for Stage 2 infection was 5.18 (95% CI: 1.48-16.97; p=0.009) and for Stage 3 infection was 4.52 (95% CI: 1.76-11.59; p=0.002). Complete vaccination was a significant predictor of longterm symptoms with adjusted OR 3.65 (95% CI 1.22-10.91; p=0.021).
CONCLUSION: This study demonstrated that neuropsychiatric symptoms were common among COVID-19 patients in Johor, Malaysia and the risk of these symptoms was associated with the severity of the infection. Additionally, complete vaccination does not completely protect against long-term neuropsychiatric deficits. This is crucial for continuous monitoring and addressing neuropsychiatric symptoms in COVID-19 survivors.

Zainal M, Goh PP

Med J Malaysia, 1997 Mar;52(1):12-6.
PMID: 10968048

One hundred and sixty seven (167) perforating eye injuries involving 159 patients were analyzed in a retrospective study over a three-year period. The degree of blindness and their associated factors were determined. Most patients were in the first three decades of life and were males. One hundred and seven (64%) eyes had vision of 3/60 or worse at initial assessment. Of these only 45% of eyes had improved vision to 6/36 or better at six months of follow-up. Fifty-five per cent of eyes were blind. The only significant associated factor identified was the extent of injury. Age, time interval and mechanism of injury were not significant factors.

Norashikin J, Roshan TM, Rosline H, Zaidah AW, Suhair AA, Rapiaah M

Southeast Asian J. Trop. Med. Public Health, 2006 Mar;37(2):370-3.
PMID: 17125001

Iron deficiency is the commonest cause of anemia worldwide and healthy blood donors are estimated to lose about 236 mg of iron with each donation. The objective of this study was to determine the serum ferritin levels among first time and regular male blood donors, and also to correlate the serum ferritin levels with the number of donations and hemoglobin levels. Hemoglobin levels and serum ferritin were measured in three groups of donors divided into first time donors; (n = 92), donors with 2-4 donations (n = 41), and regular donors (n = 78). The mean hemoglobins in the first time donors, second group and regular blood donor group were 14.95 +/- 1.08, 15.12 +/- 1.44 and 15.56 +/- 1.48, respectively. The serum ferritin level were found to be significantly lower among the regular donors (62.0 +/- 39.78 ng/ml) compared to first time donors (90.7 +/- 66.63) and second group donors (114.12 +/- 66.97). The serum ferritin levels gradually decrease according to the number of donations and there was a significant correlation between frequency of donations and the serum ferritin level (r2 = 0.082). Significant correlation between the number of donations and hemoglobin level r2 = 0.061) was noted. However, there was no significant correlation between hemoglobin and serum ferritin levels (r2 = 0.015). Eleven percent of regular donors had depleted iron stores. This was not noted in donors who donated less than 5 times within 2 years.

PMID: 11993896

The concordance between endoscopic and histological gastritis was determined in 52 patients referred for upper gastrointestinal endoscopy. The study was conducted in Northeastern Peninsular Malaysia, an area with a low background prevalence of H. pylori infection. Endoscopic and histological gastritis were assessed in accordance with the Sydney System. The results showed poor concordance between endoscopic and histological gastritis even after reclassifying mild endoscopic gastritis as normal. The low prevalence of H. pylori was validated in this study.

Nor Saleha IT, Noor Hassim I

Ind Health, 2006 Oct;44(4):584-91.
PMID: 17085919

Noise is one of the hazards faced by workers. A cross-sectional study was conducted among industries in Negeri Sembilan with the objective to assess their compliance to Hearing Conservation Programme (HCP). The other objectives of this study were to determine the factors influencing it and to show the industries' compliance to each element of the programme. It was also to identify the association between compliance to HCP and the prevalence of hearing impairment and standard threshold shift. Data for this study were collected using questionnaires sent by mail and also the results of the latest audiometric tests. A total of 167 industries were analysed for this study. It was found that 41.3% of these industries fully complied to the programme. It was also found that the industries preferred to provide hearing protection device (92.8%) and least complied to noise control (61.1%). There were significant associations (p<0.05) between compliance and number of employees, status of ownership and the presence of officer in charge of hearing conservation programme. Having at least 150 employees actually raised the compliance to HCP in two folds (beta = 0.717, OR = 2.048, C.I 95% = 1.063 to 3.944). The prevalences of hearing impairment and standard threshold shift were 23.9% and 5.2% respectively. There was no significant association between the prevalence for hearing impairment and compliance to HCP. The prevalence for standard threshold shift was inversely related to compliance. This study showed that compliance percentage need to be improved as an effort to prevent the hearing problems among workers exposed to noise.

Tajik E, Abd Latiff L, Adznam SN, Awang H, Yit Siew C, Abu Bakar AS

J Sports Med Phys Fitness, 2017 Oct;57(10):1382-1387.
PMID: 28004901 DOI: 10.23736/S0022-4707.16.06658-5

BACKGROUND: Inadequate physical activity has adverse health consequences among adolescents. Mental health problem can be developed by lack of physical activity however it is controversial. The current study aimed to examine the association between level of physical activity with depression, anxiety and stress symptoms among adolescents.
METHODS: A representative sample of 1747 adolescents (13-14 years) was randomly selected from 6 schools in a south part of Malaysia. Respondents were asked to fill consent form, and questionnaires including Depression Anxiety and Stress Scale-21 and Physical Activity Questionnaire for Adolescents.
RESULTS: Majority of respondents (71.9%) was Malay and more than half of the adolescents had low physical activity. About 40% had depression symptoms, followed by anxiety symptoms (65.9%) and stress symptoms (38.5%). Level of physical activity was significantly associated with gender, anxiety and stress (P<0.001). There were no associations with race, religion and depression symptom.
CONCLUSIONS: This study provides some evidence among school-going adolescents related to anxiety and stress symptoms and low physical activities. Further studies are needed to show the protection effects of higher physical activity for depression, anxiety and stress symptoms in adolescents.

Fulltext A study on perennial rhinitis in Kelantan

Elango S, Purohit GN, Gan SC, Manap Z, Raza H

Med J Malaysia, 1989 Sep;44(3):231-5.
PMID: 2696872

Ninety five patients with perennial rhinitis were examined clinically and various investigations were done in order to find out the common allergens and to assess the value of various tests in perennial rhinitis. In this study group 94% of cases were proven to be cases of allergic rhinitis. Cat fur was found to be the commonest allergen. Grass pollen which is a common allergen in European countries was found in only 18% of cases in the present study. X-ray of the paranasal sinuses as a routine investigation was not found to be of much use in perennial rhinitis. There was significant correlation between results for allergens tested by enzyme immunoassay and skin prick test.

PMID: 19287357

A survey of Caseous Lymphadenitis (CLA), a bacterial infection in sheep and goats was conducted on small ruminant farms in two districts in Perak, namely Kinta and Hilir Perak. The objective of this survey is to determine the status of CLA infection in small ruminants. A total of 8 farms were screened, involving a total of 579 animals. Agar Gel Precipitation Test (AGPT) and Enzyme Linked Immuno Absorbent Assay (ELISA) were conducted on serum samples obtained from the animals. Results show that 8.5% of the animals had a positive reaction for AGPT test. It was found that 36 samples (17%) were found positive using both AGPT and ELISA methods, 9 samples (4%) were found positive only using AGPT method, 14 samples (6%)were found positive only using ELISA and 157 samples (73%) were found negative using both methods. Since there is no available data on the prevalence of the disease in the country, further epidemiological studies as well as reliable diagnostic detection methods need to be assessed for aiding in control and eradication programmes for this disease.

A survey of coccidian infections of freshwater fishes of Peninsular Malaysia, with descriptions of three species of Goussia Labbé, 1896 (Apicomplexa: Eimeriidae)

Molnár K, Shaharom-Harrison F, Székely C

Syst Parasitol, 2003 May;55(1):11-8.
PMID: 12815211

Ninety-five specimens of 14 freshwater fish species from small streams in the Kuala Terengganu district and the Lake Kenyir Reservoir, Malaysia, were surveyed for coccidian infections. Six fish species proved to be infected with apicomplexans belonging to the genus Goussia. In all of these fishes Goussia species were found in unsporulated and semisporulated stages. Oöcysts of four species inhabiting the intestinal epithelium became sporulated in tap-water within 24 hours. In two fish species sporulation failed and only unsporulated oöcysts were recorded in the intestine. Three of the intestinal species finishing sporulation proved to be new to science and were described as Goussia malayensis n. sp., G. bettae n. sp. and G. pogonognathi n. sp. from Apocheilus panchax, Betta splendens and Hemirhamphodon pogonognatus, respectively. The fourth species, found in Trichogaster pectoralis, was identified as G. trichogasteri Székely & Molnár, 1992, a species known from aquarium-cultured T. trichopterus.

Fulltext A survey of knowledge of sexually transmitted infections among patients at a public hospital in Pulau Pinang, Malaysia

Anwar M, Sulaiman SA, Khan TM

Med Princ Pract, 2010;19(4):312-8.
PMID: 20516709 DOI: 10.1159/000312719

OBJECTIVE: The aim of this study was to assess the patients' knowledge and awareness of sexually transmitted infections (STIs).
SUBJECTS AND METHODS: A face-to-face interview was conducted among the patients visiting the Venereal Diseases Outpatient Department of the General Hospital of Pulau Pinang (Malaysia). A 19-item questionnaire was used. A total of 116 patients participated in the study and 107 patients had valid responses. The reliability and internal consistency of the questionnaire tool was estimated on the basis of Cronbach's alpha (= 0.81). The Statistical Package for Social Sciences (SPSS 13.0(R)) was used for data analysis. Student's t test and analysis of variance were used to analyse the knowledge differences among the groups.
RESULTS: Of the 107 patients, 82 (76.6%) were diagnosed with syphilis; AIDS was the most commonly known STI among the patients. Of the 107 patients, 35 were sexually active and of these 23 (65.7%) had more than 1 sexual partner. The most popular source of knowledge was newspapers (51 patients, 47.7%), with hospitals (3 patients, 2.8%) being the least popular one. Overall mean score on knowledge questions was 12.21 out of the maximum of 33 points. Knowledge about causative organisms, risk groups, transmission, symptoms, prevention and treatment of STIs was inadequate. The knowledge level was significantly related to gender (p = 0.03), religion (p = 0.005), educational level (p = 0.000), marital status (p = 0.000) and income level (p = 0.036).
CONCLUSION: This study demonstrated evidence of poor knowledge of STIs amongst the patients attending an STI service in the General Hospital of Pulau Pinang (Malaysia). Hence there is an immediate need for efforts towards improving patient knowledge of STIs.
Study site: Venereal Diseases Outpatient Department, General Hospital Pulau Pinang, Malaysia

Fulltext A survey of simian Plasmodium infections in humans in West Kalimantan, Indonesia

Sugiarto SR, Natalia D, Mohamad DSA, Rosli N, Davis WA, Baird JK, et al.

Sci Rep, 2022 Nov 03;12(1):18546.
PMID: 36329096 DOI: 10.1038/s41598-022-21570-0

The simian parasite Plasmodium knowlesi is the predominant species causing human malaria infection, including hospitalisations for severe disease and death, in Malaysian Borneo. By contrast, there have been only a few case reports of knowlesi malaria from Indonesian Borneo. This situation seems paradoxical since both regions share the same natural macaque hosts and Anopheles mosquito vectors, and therefore have a similar epidemiologically estimated risk of infection. To determine whether there is a true cross-border disparity in P. knowlesi prevalence, we conducted a community-based malaria screening study using PCR in Kapuas Hulu District, West Kalimantan. Blood samples were taken between April and September 2019 from 1000 people aged 6 months to 85 years attending health care facilities at 27 study sites within or close to jungle areas. There were 16 Plasmodium positive samples by PCR, five human malarias (two Plasmodium vivax, two Plasmodium ovale and one Plasmodium malariae) and 11 in which no species could be definitively identified. These data suggest that, if present, simian malarias including P. knowlesi are rare in the Kapuas Hulu District of West Kalimantan, Indonesian Borneo compared to geographically adjacent areas of Malaysian Borneo. The reason for this discrepancy, if confirmed in other epidemiologically similar regions of Indonesian Borneo, warrants further studies targeting possible cross-border differences in human activities in forested areas, together with more detailed surveys to complement the limited data relating to monkey hosts and Anopheles mosquito vectors in Indonesian Borneo.

A survey of the current practice of obstetric anaesthesia and analgesia in Malaysia [correction of Malaysis]

Chan YK, Ng KP

J Obstet Gynaecol Res, 2000 Apr;26(2):137-40.
PMID: 10870307

OBJECTIVE: A survey covering 30% of the deliveries in Malaysia was done to determine the practice of obstetric anaesthesia and analgesia for 1996.
RESULTS: From the survey, it was found that the regional anaesthesia rate for caesarean section was 46% in the government hospitals compared to 29.2% in the private hospitals, with spinal anaesthesia being the most common regional anaesthetic technique used in both types of hospitals. The epidural rate for labour analgesia was only 1.5% overall for the country. Epidural analgesia services were available in all private hospitals whereas 17.6% of government hospitals surveyed did not offer this service at all.
CONCLUSIONS: Although the use of epidural analgesia for labour was low in Malaysia, the overall rate of regional anaesthesia for caesarean section (41.9%) is very much in keeping with the standards of safe practice recommended by the United Kingdom.
