The aim of the present study was to assess the anti-obesity and lipolysis effects of Strobilanthes
crispus leaves extract (SCE) in diet-induced obese (DIO) rats by administering 1% (w/w) of
SCE in drinking water. Methods: Normal Sprague-Dawley rats were induced obese using a
high-fat (HF) diet formulation for 14 weeks. DIO rats were subsequently treated with 1% (w/w)
SCE while the HF diet was switched to normal rat chow diet. Food intake, water intake and
bodyweight were measured weekly. Other parameters e.g. blood lipid profile were determined
in normal and DIO rats before and after treatment with SCE. Histopathological changes in the
liver were also observed after treatment. Results: Prior to treatment, DIO rats have significantly
higher (p

Stress reduces the performance and productivity of employees.
One of the most important stressors originate from organizational factors,
which are decision latitude, psychological demand, social support and job
insecurity. This creates four kinds of jobs: passive, active, low strain and high
strain. The objective of the study is to determine the association between
organizational factors with occupational stress and cortisol level among
lecturers in University Selangor. This cross-sectional study used a purposive
sampling, which involved 45 lecturers from various faculties. The instrument
used in this study was Job Content Questionnaire (JCQ) which is a
Psychosocial Job Assessment Instrument designed by Karasek et al., (1998).
The questionnaire has been translated to Malay version by Edimansyah et al.,
(2006). 10ml of blood sample was collected from each respondent by certified
phlebotomist. Results from the statistical analysis showed that majority of the
respondents were female (75.6%), aged below forty years old (82.2%), married
(77.8%) and hold a master degree (68.9%). Most of the respondents were
found having low decision latitude 35(77.5%). Majority of the respondents
were also found in passive group 13(28.9%) which were having low
psychological job demand and low decision latitude, while others are in low
strain 11(24.4%), high strain 11(24.4%) and active group 10(22.2%)
respectively. There was a significant association between two organizational
factors with occupational stress level, which are decision latitude and
psychological job demand (p0.05). As a
conclusion, two out of four organizational factors, which are decision latitude
and psychological job demand showed a significant association with
occupational stress levels. Cortisol as one of stress biomarkers may not be
significant due to small sample size.

Malays J Pathol, 1998 Dec;20(2):113-4.
PMID: 10879273

A clinicohistological study of acute atherosis in molar pregnancy was undertaken. Maternal decidual vessels in currettage samples of 38 histologically confirmed complete hydatidiform moles were examined histologically for acute atherosis, recognised as fibrinoid necrosis of the smooth muscle wall with a perivascular mononuclear cell infiltrate, with or without lipophages. Acute atherosis was detected in eight of 38 cases, an incidence of 18.4%. All the patients were normotensive. The significance of acute atherosis in molar pregnancy remains to be clarified.

Mahanom H, Azizah A, Dzulkifly M

Malays J Nutr, 1999 Dec;5(1):47-54.
PMID: 22692357

The effect of oven drying at 50ᵒC ± 1ᵒC for 9 hour, 70ᵒC ± 1ᵒC for 5 hour and freeze drying on retention of chlorophyll, riboflavin, niacin, ascorbic acid and carotenoids in herbal preparation consisting of 8 medicinal plants was evaluated. The medicinal plants selected were leaves of Apium graveolens (saderi), Averrhoa bilimbi (belimbing buluh), Centella asiatica (pegaga), Mentha arvensis (pudina), Psidium guajava (jambu batu), Sauropus androgynous (cekor manis), Solanum nigrum (terung meranti) and Polygonum minus (kesum ). Results revealed that both type and conditions of the drying treatments affected retention of all phytochemicals analysed. Herbal preparation developed using oven drying was found to have inferior phytochemicals content compared to that obtained by freeze dryer. Nevertheless, the herbal preparation developed using all treatments still retain appreciable amount of phytochemicals studied, especially carotenoids, ascorbic acid, niacin and riboflavin and thus have potential for commercial purposes.

Comparison of rates of smoking across countries revealed that students are more likely to begin smoking in medical school than to give it up and increase their cigarette consumption rather than decrease it. A cross-sectional survey of all consenting medical students in a private medical university in north Malaysia was conducted in 2008 to determine the prevalence and smoking habits among them. A self administered questionnaire which was returned to the investigators in a sealed envelope was used. Results were tabulated and analysed with SPSS version 13.0 software. The response rate was 83.3% (508/610). The prevalence rate for current smokers was 5.3% (27/508) and for ever smokers 9.3% (47/508). Factors significantly associated with smoking were gender (p<0.001), age group (p<0.001) and family income (p=0.003). The odds of being a smoker was 14 folds high when a family member smoked and the odds of being an ever smoker was almost 6 folds more when a family member smoked. Friends were the most common influence to start smoking and the most common reason to stop smoking among ever smokers. The reasons for not smoking among the never smokers were health concerns and the distasteful smell of cigarettes. A module on how to help medical students to stop smoking should be included in the curriculum of every medical school. This will not only help them become good educators but will prevent them from picking up the habit. Educational intervention should also include family members who smoke.

Bisecting-angle-technique is a method used to improve patient comfort during periapical radiography. This technique is usually performed without X-ray beam aiming device and has been commonly associated with dental radiographic error. The use of external marker as a beam aiming device in bisecting-angle-technique is potentially effective to reduce the number of errors occurring during periapical radiography. In this study, 240 periapical radiographs were taken by undergraduate dental students. Periapical radiographs were taken using traditional method of bisecting-angle-technique (BAT), bisecting-angle-technique with the use of external marker (BAT-M) and the standard method in periapical radiography; paralleling technique (PT). All radiographic images were evaluated and errors were classified and tabled according to the type and number of errors. Chi-square test was used to compare the total number of radiographic errors made using these three techniques. One of the most common errors with BAT was cone cut error (13.8%). This error had been markedly reduced to 1.3% and 2.5% by implementation of BAT-M and PT, respectively. The total number of errors was also found to be significantly lesser for BAT-M compared to BAT, p< 0.05.

Rashid A, Azizah A

Australas Med J, 2011;4(6):283-90.
PMID: 23386889 DOI: 10.4066/AMJ.2011.660

BACKGROUND: We are living in an ageing world. The prevalence of hypertension which is an established risk factor for cardiovascular disease and stroke increases with age. The aim of the study was to determine the prevalence of hypertension among the elderly Malays living in rural parts of north Malaysia.
METHOD: This cross-sectional study was conducted among the elderly (aged ≥60) Malay residents living in 22 villages in a northwestern state called Kedah in Malaysia from 2007 to 2009. Kedah has one of the highest rates of elderly population in the country. Data was collected by trained research assistants. Besides the baseline demographic information, blood pressure was measured using standardised methods using a manual sphygmomanometer.
RESULTS: The response rate was 97.7%. The prevalence of hypertension among the elderly in these villages was 54.5% (228), 118 (28.2%) were known to be hypertensive and were on medication and an additional 110 (26.3%) respondents were newly diagnosed. Elevated mean systolic (146.17 ± 25.23) and diastolic (89.68 ± 15.60) blood pressure was noted among the known hypertensive. There was an almost fourfold risk (OR 3.64) of having uncontrolled blood pressure among the known hypertensive on treatment. Those with malnutrition were at an almost twofold at risk of being hypertensive (OR 1.73). Binary logistics regression showed occupation (OR 1.65), marital status (OR 2.32) and body mass index (BMI) (OR 1.62) as significant predictor variables.
CONCLUSION: Screening the elderly for hypertension will benefit this group of people by reducing the morbidity and mortality associated with this condition.

Cognitive impairment is a common psychiatric problem among the elderly. The objective of the study was to determine the prevalence of cognitive impairment among the elderly Malays living in a rural community in north Malaysia. A cross sectional study was conducted among the elderly population of 22 villages in north Malaysia. Elderly cognitive assessment questionnaire was used to determine the cognition status. Analysis was done using SPSS version 13. The prevalence of cognitive impairment among the older adults in these villages was 11% (n=46). There was an increasing prevalence of cognitive impairment with increasing age (p < 0.05). Being unmarried (OR 2.31), unemployed (OR 2.74) and living alone (OR 2.32) were significantly associated with the risk of being cognitively impairment. Being unemployed (OR 2.29) was a significant predictor variable for cognitive impairment. Similar to other studies conducted in Malaysia the prevalence of cognitive impairment was high.

A study to quantify the free glutamic acid content of six processed foods, 44 dishes and 26 condiments available in Malaysia was performed using high-performance liquid chromatography with a fluorescence detector (HPLC-FRD). Recovery tests were carried out with spiked samples at levels from 6 to 31 mg g(-1). High recovery in different matrices was achieved ranging from 88% +/- 13% to 102% +/- 5.12%, with an average of 97% +/- 8.92%. Results from the study revealed that the average free glutamic acid content ranged from 0.34 +/- 0.20 to 4.63 +/- 0.41 mg g(-1) in processed foods, while in prepared dishes it was as low as 0.24 +/- 0.15 mg g(-1) in roti canai (puffed bread served with curry or dhal) to 8.16 +/- 1.99 mg g(-1) in dim sum (a small casing of dough, usually filled with minced meat, seafood, and vegetables, either steamed or fried). Relatively, the content of free glutamic acid was found to be higher in condiments at 0.28 +/- 0 mg g(-1) in mayonnaise to 170.90 +/- 6.40 mg g(-1) in chicken stock powder.

PMID: 30121692 MyJurnal

Kawasaki disease (KD) is an acute systemic vasculitis usually affecting children <5 years old. We report a 44-dayold baby who had persistent fever despite being on antibiotics for presumed sepsis. Erythema of Bacillus Calmette-Guerin (BCG) scar and thrombocytosis were noted on day-2 of illness. Diagnosis of incomplete KD was made on the 10th day of illness. Her fever resolved with intravenous immunoglobulin, but echocardiogram revealed coronary artery aneurysm. High index of suspicion is required to diagnose KD in infants ≤3 months since it is rare and commonly presents with incomplete clinical features. The presence of unexplained fever for ≥5 days with erythema of BCG scar or thrombocytosis in infants should alert the clinicians of KD.
Toxicity study and blood pressure-lowering efficacy of whey protein concentrate hydrolysate in rat models, plus peptide characterization

Hussein FA, Chay SY, Ghanisma SBM, Zarei M, Auwal SM, Hamid AA, et al.

PMID: 31882211 DOI: 10.3168/jds.2019-17462

We evaluated the acute (single-dose) and subacute (repeated-dose) oral toxicity of alcalase-hydrolyzed whey protein concentrate. Our acute study revealed no death or treatment-related complications, and the median lethal dose of whey protein concentrate hydrolysate was >2,500 mg/kg. In the subacute study, when the hydrolysate was fed at 3 different concentrations (200, 400, and 800 mg/kg), no groups showed toxicity changes compared with controls. Then, whey protein concentrate hydrolysate was orally administered to spontaneously hypertensive rats. Results revealed significant reductions in blood pressure in a dose-dependent manner, and dosing at 400 mg/kg led to significant blood pressure reduction (-47.8 mm Hg) compared with controls (blood pressure maintained) and the findings of previous work (-21 mm Hg). Eight peptides-RHPEYAVSVLLR, GGAPPAGRL, GPPLPRL, ELKPTPEGDL, VLSELPEP, DAQSAPLRVY, RDMPIQAF, and LEQVLPRD-were sequentially identified and characterized. Of the peptides, VLSELPEP and LEQVLPRD showed the most prominent in vitro angiotensin-I converting enzyme inhibition with half-maximal inhibitory concentrations of 0.049 and 0.043 mM, respectively. These findings establish strong evidence for the in vitro and in vivo potential of whey protein concentrate hydrolysate to act as a safe, natural functional food ingredient that exerts antihypertensive activity.

Transforming growth factor beta-1 (TGF-beta-1) is a multifunctional cytokine involved in the regulation of growth and differentiation of both normal and transformed cells. The main aim of this study was to determine whether TGF-beta-1 or alpha fetoprotein (AFP) or the combination of the two is a better indicator for hepatocellularcarcinoma (HCC). Serum TGF-beta-1 and AFP were measured by ELISA in 40 healthy subjects, 23 patients with hepatocellular carcinoma (HCC), 70 patients with hepatitis B, 26 patients with hepatitis C and 16 patients with liver cirrhosis (LC). Patients with liver diseases showed significantly higher serum TGF-beta-1 values (> 3 fold) compared to control subjects. As for serum AFP, significant elevation was only observed for HCC cases. Serum TGF-beta-1 exhibited higher percent sensitivity compared to serum AFP in all liver diseases. Combination of serum TGF-beta-1 and AFP increased specificities in all cases studied. In conclusion, serum TGF-beta-1 is a more sensitive marker for HCC when compared to serum AFP and its specificity is increased when combined with serum AFP.

INTRODUCTION: Urinary tract infection (UTI) is a common bacterial infection affecting children and therefore, prompt recognition and accurate antimicrobial management are vital to prevent kidney damage. This study aims to determine the bacterial pathogens and their patterns of antimicrobial resistance in children presenting with UTI.
METHODS: A retrospective study of 721 cases, involving children between the ages of 1-day old to 13 years old with culture-proven UTI in Selayang Hospital, Malaysia between January 2007 and December 2011. The bacterial pathogens and antibiotic resistance patterns in the total population, prophylaxis and no prophylaxis groups were studied.
RESULTS: The 3 most common organisms isolated in the total population were E.Coli (41.6%), Klebsiella spp. (21.2%) and Enterococcus spp. (11.0%). With regards to the antibiotic resistance, E.Coli resistance rates to ampicillin, cefuroxime and gentamicin were 67.7%, 15.3% and 7.3% respectively. Ampicillin-resistance was also highest in Klebsiella spp. (84.3%), Enterococcus spp. (15.5%) and Proteus spp. (55.5%).
CONCLUSION: E.coli remains to be the leading bacterial pathogen causing UTI in children, with ampicillin-resistance occurring in more than half of these cases. Therefore, accurate choice of antibiotics is important to ensure optimal outcome. In our study, cefuroxime and gentamicin have lower antibiotic resistance rates and can be used in the treatment of UTI in children.
