Introduction: Greater needs of medical doctors to provide appropriate care for both genders related diseases, however men face more problem since their problems have less been recognized. Objective: The objective was to determine the level of men’s health knowledge among final year medical students in USM and MU. Method: A total of 199 final year medical students from Universiti Sains Malaysia (USM), Kelantan, Malaysia and Monash University, Melbourne, Australia (75 students from USM and 124 students from MU) were enrolled in the study and completed self-administered questionnaire on the topics related to male sexual and reproductive health. Result: The response rate for USM and MU was 44% and 68.9% respectively. Out of 52 items, 17 items were significantly had higher percentage in answering correctly (p
Investigation of the dependence of inactivation coefficient on pertinent physical quality parameters to low doses ionizing radiation

Yousif AA, Bin Bahari I, Yasir MS

Curr Radiopharm, 2012 Jan;5(1):34-7.
PMID: 21864247

Inactivation constant for V79 cells has been extracted from radiobiology experiments that utilize charged particles to irradiate mammal cells in vitro. Physical parameters such as effective charge, radiation mean free path and linear ionization which characterized protons and heluim-4 particles are determined using of standard values. The relationship between inactivation constant α and physical quality parameters have been determined, in this research, for protons and heluim-4 particles. This approach allows getting the characteristic biological response of inactivation of V79 cells in terms of each selected physical quality parameter. The best regression models are formulated for each obtained relationship.

PMID: 17428589

The processing of amang, or tin tailings, for valuable minerals has been shown to technologically enhance NORM and this has stirred significant radiological safety and health concerns among Malaysia's regulatory authority. A growing radiological concern is now focused on the amang effluent containing NORM in recycling ponds, since these ponds may be reclaimed for future residential developments. A study was carried out to assess the radiological risk associated with amang processing and the accumulated effluent in the recycling ponds. Twenty-six sediment samples from the recycling ponds of two amang plants in the states of Selangor and Perak, Malaysia, were collected and analyzed. The maximum activity concentrations of (238)U, (226)Ra, (232)Th and (40)K recorded in sediments from these ponds were higher than Malaysia's and the world's natural highest. Correspondingly, the mean radium equivalent activity concentration indices, Ra(eq), and gamma radiation representative level index, I(gammar), were higher than the world's average. The enhancement of NORM in effluent sediments as a consequence of amang processing, and the use of a closed water management recycling system created Effective Dose Rates, E (nSv h(-1)), that signal potential environmental radiological risks in these ponds, should they be reclaimed for future land use.
Micronucleated erythrocytes as an assay to assess actions by physical and chemical genotoxic agents in Clarias gariepinus

Bahari IB, Noor FM, Daud NM

Mutat Res, 1994 Aug;313(1):1-5.
PMID: 7519306

An in vivo study on the effects of both physical (gamma-radiation) and chemical (mitomycin C) genotoxic agents was carried out with the catfish species, Clarias gariepinus. The fish were either exposed to gamma-radiation at doses of 0-9 Gy or injected intraperitoneally with mitomycin C at concentrations of 0-2 mg/kg. Micronucleated erythrocytes were sampled from 0 to 60 days post treatment. Data obtained showed a time-dependent response of the induction of micronucleated erythrocytes with both genotoxic agents. A linear dose-dependent increase was observed 2-4 days after treatment. These data show the importance of sampling time in the micronucleus assay with Clarias gariepinus.

PMID: 31435320 DOI: 10.1016/j.jtumed.2017.10.001

Objectives: This study aimed to determine the prevalence of premature ejaculation and its associated factors among men attending a primary healthcare clinic in Kota Bharu, Kelantan, Malaysia.

Methods: A cross-sectional study was conducted on 18- to 60-year-old sexually active men during at least the past 6 months. Patients with unstable psychiatric illnesses, mental retardation, and illiteracy were excluded. A questionnaire on sociodemographic factors, Malay version Premature Ejaculation Diagnostic Tool, and Malay version International Index Erectile Function-5 were distributed. Premature ejaculation was defined as a Premature Ejaculation Diagnostic Tool score of 9 and above. Descriptive analysis and simple and multiple logistic regression analyses were performed using SPSS version 22.

Results: A total of 294 of 313 eligible men responded, with a response rate of 93.9%. The prevalence of premature ejaculation was 21.4% (n = 63). The multiple logistic regression analysis showed that mild [adj. OR (95% CI): 5.6 (1.89, 16.91); P = 0.002], mild-moderate [adj. OR (95% CI): 8.2 (2.72, 24.46); P
Fulltext Metoprolol for prophylaxis of postoperative atrial fibrillation in cardiac surgery patients: systematic review and meta-analysis

Norhayati MN, Shaiful Bahari I, Zaharah S, Nik Hazlina NH, Mohammad Aimanazrul Z, Irfan M

BMJ Open, 2020 10 31;10(10):e038364.
PMID: 33130564 DOI: 10.1136/bmjopen-2020-038364

PURPOSE: Postoperative atrial fibrillation (POAF) is a potentially lethal and morbid complication after open heart surgery. This systematic review and meta-analysis aimed to investigate metoprolol compared with other treatments for prophylaxis against POAF.
METHODS: We searched CENTRAL, MEDLINE, EMBASE and trial registries for randomised controlled trials that evaluated metoprolol for preventing the occurrence of POAF after surgery against other treatments or placebo. Random-effects model was used for estimating the risk ratios (RRs) and mean differences with 95% CIs.
RESULTS: Nine trials involving 1570 patients showed metoprolol reduced POAF compared with placebo (416 patients; RR 0.46, 95% CI 0.33 to 0.66; I²=21%; risk difference (RD) -0.19, 95% CI -0.28 to -0.10). However, metoprolol increased the risk of POAF compared with carvedilol (159 patients; RR 1.59, 95% CI 1.20 to 2.12; I²=4%; RD 0.13, 95% CI 0.06 to 0.20). There was no difference when compared with sotalol or amiodarone. The occurrence of cardiovascular conditions after drugs administration or death between the groups was not different. The overall quality of evidence was moderate to high. Subgroup analysis and funnel plot were not performed.
CONCLUSIONS: Metoprolol is effective in preventing POAF compared with placebo and showed no difference with class III antiarrhythmic drugs. Death and thromboembolism are associated with open heart surgery, but not significant in relation to the use of metoprolol.

BACKGROUND: Over the last two decades, there has been significant growth in public, political, and academic awareness of polygamy. Polygamous families have distinct household problems, usually stemming from jealousy between co-wives over the husband's affections and resources. This study aimed to ascertain the psychological impact of polygamous marriage on women and children worldwide.
METHODS: A systematic search was performed in MEDLINE (PubMed), Scopus, CINAHL (EBSCOhost), Google Scholar, and ProQuest using search terms such as "marriage" and "polygamy." Studies published from the inception of the respective databases until April 2021 were retrieved to assess their eligibility for inclusion in this study. The Joanna Briggs Institute Critical Appraisal Checklist was used for data extraction and the quality assessment of the included studies. The generic inverse variance and odds ratios with 95% confidence intervals (CI) were calculated using RevMan software.
RESULTS: There were 24 studies fulfilling the eligibility criteria, and 23 studies had a low risk of bias. The pooled meta-analysis showed women in polygamous marriages had a 2.25 (95% CI: 1.20, 4.20) higher chance of experiencing depression than in monogamous marriages. Children with polygamous parents had a significantly higher Global Severity Index with a mean difference of 0.21 (95% CI: 0.10, 0.33) than those with monogamous parents.
CONCLUSIONS: The psychological impact of polygamous marriage on women and children was found to be relatively higher than monogamous marriage. Awareness of the proper practices for polygamy should be strengthened so that its adverse effects can be minimized. The agencies involved in polygamous practices should broaden and enhance their understanding of the correct practice of polygamy.
