Ramzisham AR, Arief H, Ngoo KS, Zamrin DM, Joanna OS

Clin Ter, 2011;162(6):553-4.

PMID: 22262328

Acute aortic dissection is a life-threatening condition, warranting prompt diagnosis and treatment. Management of which incorporates multidisciplinary expertise from the medical, surgical and intensive care. If left untreated, the mortality rate of acute aortic disease exceeds 50% within 48 hours and 80% within two weeks, with a 5-year survival rate of 19%. The most common cause of death in untreated acute aortic dissection, regardless of aetiology, is aortic rupture. We would like to share our successful experience of cases at the two extreme ages of acute aortic dissection. Literature review with their pathogenesis are discussed.

Fulltext Is it necessary to excise all breast lesions? Experience from a university-based breast unit

Ng CH, Nur-Aishah T

Malays Fam Physician, 2009;4(2-3):66-70.

PMID: 25606166 MyJurnal

Breast cancer is becoming more important in Asia since it affect the younger age group. Question arises whether it is safe for breast lesions to be left in-situ if all the elements in triple assessment are benign. The aim of this study is to audit all the excision biopsies of breast lumps done in the University Malaya Medical Centre (UMMC), to review the association of age with the type of pathological finding and to evaluate the rate of carcinoma in these biopsies.

Female transfer between one-male groups of proboscis monkey (Nasalis larvatus)

Murai T, Mohamed M, Bernard H, Mahedi PA, Saburi R, Higashi S

Primates, 2007 Apr;48(2):117-21.

PMID: 16871366

Successful or unsuccessful female transfers were observed seven times during a 32-month field study of proboscis monkeys (Nasalis larvatus) inhabiting a riverine forest along a tributary of the Kinabatangan River, Sabah, Malaysia. In all cases, the females voluntarily left their own groups and immediately joined with another one. When adult females tried to shift to other groups, adult males called them back to their own groups, but appeared to be indifferent to subadult females. When the adult females returned, the males never attacked the females physically, but instead often emitted herding sounds to them. One subadult female was repelled by a resident adult female. When one adult female transferred into a new one-male group, she left her behind son in an all-male group. The number of females often fluctuated in most study groups, with this fluctuation being more prominent among subadult females than adult females. It is likely that female transfer in proboscis monkeys is not a rare occurrence and that it is especially common among sub-adult females.

Distribution of molar mass and branching index of natural rubber from Hevea brasiliensis trees of different age by size exclusion chromatography coupled with online viscometry

Phan TN, Lan NT, Nga NT

Med J Malaysia, 2004 May;59 Suppl B:214-5.

PMID: 15468894

Natural rubber from hevea brasiliensis trees (Thailand, RRIM 600 clone) of different age (8, 20, and 35 years) were characterized by size exclusion chromatography coupled with online viscometry according to their distribution of molar mass and branching index at a temperature of 70 degrees C using cyclohexane as solvent. Washing with an aqueous solution of sodium dodecylsulfate and subsequent saponification purified the natural rubber samples. With this procedure physical branching points caused by phospholipids, proteins and hydrophobic terminal units, mainly fatty acids, of the natural rubber (cis-1,4-polyisoprene) molecule, could be removed leading to completely soluble polymer samples. All samples investigated possess a very broad (10 to 50,000 kg/mol) and distinct bimodal molar mass distribution. With increasing age the peak area in the low molar mass region decreases favoring the peak area in the high molar mass region. By plotting the branching index as a function of the both, the molar mass and the age of the trees.

Shemu PL, Ahmad N, Lim PY, Suchi PM

Afr J Reprod Health, 2022 Apr;26(4):32-41.

PMID: 37584982 DOI: 10.29063/ajrh2022/v26i4.4

This study aimed at determining the factors that influence family planning practice among rural women of Pankshin district in Plateau state, Nigeria. A cross-sectional study using a simple random sampling method was conducted from October to December 2019. A self-administered questionnaire was used for data collection among 302 respondents. Among respondents, 48.3% had practised family planning and the most popular family planning method ever practised was injectables (57.5%). The determinants of family planning practice were age group 29-39 and 40-49 years old (AOR=4.373, p <0.001; AOR=5.862, p <0.001), discussion with partner (AOR=9.192, p <0.001) and partner's approval (AOR=2.791, p=0.007). Findings showed an encouraging family planning prevalence with the main determinants involving male partners. Further efforts need to be made to promote family planning practice among male partners and to empower women of all reproductive age groups by providing them with relevant information that is needed for them to make informed decisions.

Fulltext Factors associated with good glycemic control among patients with type 2 diabetes mellitus

Ahmad NS, Islahudin F, Paraidathathu T

J Diabetes Investig, 2014 Sep;5(5):563-9.

PMID: 25411625 DOI: 10.1111/jdi.12175

AIMS/INTRODUCTION: The aim of the present study was to determine the status of glycemic control and identify factors associated with good glycemic control among diabetic patients treated at primary health clinics.

MATERIALS AND METHODS: A systematic random sample of 557 patients was selected from seven clinics in the Hulu Langat District. Data were collected from patients' medication records, glycemic control tests and structured questionnaires. Logistic regression analysis was carried out to predict factors associated with good glycemic control.

RESULTS: Variables associated with good glycemic control included age (odds ratio 1.033; 95% confidence interval 1.008-1.059) and duration of diabetes mellitus (odds ratio 0.948; 95% confidence interval 0.909-0.989). Compared with the patients who were receiving a combination of insulin and oral antidiabetics, those receiving monotherapy (odds ratio 4.797; 95% confidence interval 1.992-11.552) and a combination of oral antidiabetics (odds ratio 2.334; 95% confidence interval 1.018-5.353) were more likely to have good glycemic control. In the present study, the proportion of patients with good glycemic control was lower than that in other published studies. Older patients with a shorter duration of diabetes who were receiving monotherapy showed better glycemic control.

CONCLUSIONS: Although self-management behavior did not appear to influence glycemic control, diabetic patients should be consistently advised to restrict sugar intake, exercise, stop smoking and adhere to medication instructions. Greater effort by healthcare providers in the primary health clinics is warranted to help a greater number of patients achieve good glycemic control.

Investigation of Age Polyethism in Food Processing of the Fungus-Growing Termite Odontotermes formosanus (Blattodea: Termitidae) Using a Laboratory Artificial Rearing System

Li H, Yang M, Chen Y, Zhu N, Lee CY, Wei JQ, et al.

J Econ Entomol, 2015 Feb;108(1):266-73.

PMID: 26470129 DOI: 10.1093/jee/tou005

Laboratory rearing systems are useful models for studying Rhinotermitid behavior. Information on the biology of fungus-growing termites, however, is limited because of the difficulty of rearing colonies in the laboratory settings. The physical structure of termite nests makes it impossible to photograph or to observe colonies in the field. In this study, an artificial rearing system for field-collected colonies of the fungus-growing termite Odontotermes formosanus (Shiraki) was developed to facilitate observation in the laboratory. We recorded colony activity within the artificial rearing system and documented a variety of social behaviors that occurred throughout the food processing of the colony. This complex miniature ecosystem was cooperatively organized via division of labor in the foraging and processing of plant materials, and the observed patterns largely resembled the caste and age-based principles present in Macrotermes colonies. This work extends our insights into polyethism in the subfamily Macrotermitinae.

Prevalence and risk factors of myocardial injury in patients with COVID-19: A retrospective study

Siti Nurul Azimah MJ, Laily Noor Zuliaty A, Sharifah Shafinaz SA, Huzairi S

Med J Malaysia, 2025 Jan;80(1):96-101.

PMID: 39812435

INTRODUCTION: The coronavirus disease of 2019 (COVID-19) predominantly impacts the pulmonary system; however, it also has harmful consequences for the cardiovascular system through the occurrence of myocardial injury.

MATERIALS AND METHODS: This retrospective study analysed 119 COVID-19 patients admitted to Al-Sultan Abdullah Hospital (HASA) from March until December 2020. Demographics, medical histories, admission laboratory results, electrocardiogram (ECG), echocardiogram (echo), were captured from the hospitals' health records. Myocardial injury is an injury to the myocardium that can be diagnosed by elevated cardiac troponin T or I level above the 99th percentile upper reference limit (URL), an abnormal ECG, and an abnormal echo. Data were analysed using Statistical Package for Social Sciences (SPSS) Version 27.

RESULTS: From this study, it was founded that the prevalence of myocardial injury is 36.1% (43 subjects out of 119). The risk factors are older age (odds ratio, 2.347; p=0.028), males (odds ratio, 2.019; p=0.125), Indians (odds ratio, 3.659; p=0.296), hypertension (odds ratio, 2.776; p=0.009), diabetes mellitus (odds ratio, 1.732; p=0.155) and category 4 and 5 COVID-19 patients (odds ratio, 2.325; p=0.038).

CONCLUSION: Myocardial injury is prevalent among patients affected by COVID-19 and is associated with older age, hypertension and category 4 and 5 COVID-19. The researchers suggested conducting a more thorough investigation of the sizable population in multiple settings and conducting a prospective study where all infected COVID-19 patients have to undergo several tests, such as ECG, troponin T, and echocardiogram.

Fulltext Exploring the Characteristics and Utilization of General Practice Healthcare by Adults With Cerebral Palsy: A Systematic Review

Morgan P, Zanudin A

J Prim Care Community Health, 2025;16:21501319251320160.

PMID: 40071833 DOI: 10.1177/21501319251320160

BACKGROUND: Individuals with cerebral palsy (CP) experience acute and chronic health issues requiring lifespan primary care. This review aimed to investigate characteristics and utilization of general practitioner (GP) access by adults with CP. Secondary aims included exploring reasons prompting access, identifying interventions provided, and personal features affecting access.

METHODS: Using systematic review methodology, 5 databases were searched using keywords relating to adults, CP, and primary care, relating to quantitative studies (January 2000-July 2024). Data was extracted, collated, and analyzed descriptively, with additional meta-analyses to estimate proportion of GP visits.

RESULTS: Fifteen studies were included describing GP access by 6231 adults with CP. The proportion annually accessing a GP was 78% (95% CI = 69%-85%). The frequency of GP access ranged from 1.76 to 11.7 visits per year, increased with advancing age and disability severity. Comorbid intellectual disability and pain also increased GP attendance. Limited data was available reporting healthcare needs prompting GP access, and no interventions were described.

CONCLUSIONS: Advancing age, greater disability severity, comorbid intellectual disability, and pain may prompt increased GP access by adults with CP. Identification of reasons for seeking primary care, and interventions provided are required through data linkage studies to enhance lifespan care.

Maternal influences on low birth weight

Tin TT, Thida M, Maung MM, Wai KT

Malays J Reprod Health, 1994 Jun;12(1):32-7.

PMID: 12320337

PIP: To identify the maternal risk factors associated with low birth weight in Malaysia, the records of the 2613 infants delivered at North Okkalapa General Hospital from January to September 1990 were reviewed. The incidence of low birth weight during the 9-month study period was 21.1%; 18.1% of these cases were attributable to intrauterine growth retardation and 3% were associated with preterm births. Univariate analysis identified the following risk factors as significant: age under 20 years (.001), parity 1 (.001), maternal height of 145 cm or under (.01), maternal cigarette smoking (.01), maternal education of 8 years or less (.001), parity 5 or above (.05), and maternal age of 35 years and above (.05). A last birth interval of 1 year or less and more than 3 years was associated with an odds ratio exceeding 1, but the correlation with low birth weight was not significant. These risk factors should be used to design maternal health programs aimed at reducing the incidence of low birth weight.

Teenage births on the decline

Peng TN

Malays J Reprod Health, 1986 Dec;4(2):91-6.

PMID: 12314888

PIP: In Peninsular Malaysia, while the female population aged 15-19 years registered a growth of some 240,000 persons between 1966-1984, the number of births occurring to teenage mothers has decreased by 15,176 from 33,348 to 18,172 during the same period. In 1966, teenage births constituted some 10.8% of the total births but has declined to 4.7% by 1984. A breakdown of the 1984 data by detailed age groups shows that only 0.9% of the teenage births had actually occurred among those below 15 years of age. The declining trend in teenage births, particularly the higher order births among the very young mothers, augurs well for the improvement in family welfare. However, in order to safeguard the health and welfare of mothers and children, concerted efforts should continue to be undertaken to integrate population, family health and family life education into the school curriculum.

J Dev Econ, 1987 Aug;26(2):223-34.

PMID: 12280709

"This paper estimates a proportional hazards model for the timing of age at marriage of women in Malaysia. We hypothesize that age at marriage responds significantly to differences in male and female occupations, race, and age. We find considerable empirical support for the relevance of economic variables in determining age at marriage as well as evidence of strong differences in marriage patterns across races."
