    A series of 1, 2, 4-triazole derivatives bearing piperidine moiety has been introduced as new anti-diabetic drug candidates with least cytotoxicity. p-Chlorophenylsulfonyl chloride (1) and ethyl nipecotate (2) were the starting reagents that resulted into corresponding 3,4,5-trisubstituted-1,2,4-triazole (6) through a series of steps. A series of electrophiles, 9a-e, were synthesized by reacting 4-bromobutyryl chloride (7) with differently substituted aromatic amines (8a-e) under basic aqueous medium. Target derivatives, 10a-e, were synthesized by the reaction of compound 6 with N-aryl-4-bromobutanamides (9a-e) in an aprotic solvent. Structures of all the derivatives were verified by spectroscopic analysis using IR, 1H-NMR, 13C-NMR and EIMS. Most of the derivatives revealed moderate to good α-glucosidase inhibitory activity with reference to acarbose. The moderate hemolytic potential demonstrated least toxicity.

    A natural pentacyclic triterpenoid oleanolic acid 1 and its biotransformed metabolites 2-3 are potential α-glucosidase inhibitors. To elucidate the inhibitory mechanism of compounds 1, 2 and 3 against α-glucosidase, we calculated (i) their electronic and optical properties using DFT and TD-DFT at the B3LYP/6-31G(d) level in gas and IEF-PCM solvent; and (ii) their binding energies to α-glucosidase via docking study. DFT results showed that the α-glucosidase inhibtion is mainly depend on the polarity parameters of the studied compounds. Docking results revealed that the activity increased with binding energies (i.e. the stability of ligand-receptor complex). The specroscopic data of oleanolic acid 1 and its metabolites 2 and 3 are well predicetd for 13C NMR chemical shifts (R2=99%) and 1H NMR chemical shifts (R2=90%); and for (ii) UV/vis spectra. The assignments and interpretation of NMR chemical shifts and bathochromic shift of λMAX absorption bands are discussed.

    Cellulose acetate phthalate-based pH-responsive hydrogel was synthesized for fabrication of polymeric matrix tablets for gastro-protective delivery of loxoprofen sodium. Cellulose acetate phthalate (CAP) was cross-linked with methacrylic acid (MAA) using free radical polymerization technique. Fourier transform infrared (FTIR) spectra confirmed the formation of cross-linked structure of CAP-co-poly(methacrylic acid). Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) confirmed the thermal stability of polymeric networks, and scanning electron microscopy (SEM) and energy-dispersive X-ray spectrum (EDS) images unveiled that the prepared formulations were porous in nature and thus the developed formulations had shown better diffusibility. Swelling and in vitro drug release was performed at various pHs and maximum swelling and release was obtained at pH 7.4, while swelling and release rate was very low at pH 1.2 which confirmed the pH-responsive behavior of CAP-co-poly(MAA). CAP-co-poly(MAA) copolymer prevents the release of loxoprofen sodium into the stomach due to reduced swelling at gastric pH while showing significant swelling and drug release in the colon. Cytotoxicity studies revealed higher biocompatibility of fabricated hydrogel. Acute oral toxicity studies were performed for the evaluation and preliminary screening of safety profile of the developed hydrogels. Matrix tablets were evaluated for release behavior at simulated body pH. The investigations performed for analysis of hydrogels and fabricated matrix tablets indicated the controlled drug release and gastro-protective drug delivery of CAP-co-poly(MAA) hydrogels and pH-sensitive matrix tablets for targeted delivery of gastro-sensitive/irritative agents.

    INTRODUCTION: To determine sociodemographic and psychological factors associated with bullying behavior among young adolescents in Malaysia.
    METHODS: This is a cross-sectional study of four hundred ten 12-year-old adolescents from seven randomly sampled schools in the Federal Territory of Kuala Lumpur, Malaysia. Sociodemographic features of the adolescents and their parents, bullying behavior (Malaysian Bullying Questionnaire), ADHD symptoms (Conners Rating Scales), and internalizing and externalizing behavior (Child Behaviour Checklist) were obtained from adolescents, parents and teachers, respectively.
    RESULTS: Only male gender (OR=7.071, p=0.01*, CI=1.642-30.446) was a significant sociodemographic factor among bullies. Predominantly hyperactive (OR=2.285, p=0.00*, CI=1.507-3.467) and inattentive ADHD symptoms reported by teachers (OR=1.829, p=0.03*, CI=1.060-3.154) and parents (OR=1.709, p=0.03*, CI=1.046-2.793) were significant risk factors for bullying behavior while combined symptoms reported by young adolescents (OR=0.729, p=0.01*, CI=0.580-0.915) and teachers (OR=0.643, p=0.02*, CI=0.440-0.938) were protective against bullying behavior despite the influence of conduct behavior (OR=3.160, p=0.00*, CI=1.600-6.241). Internalizing behavior, that is, withdrawn (OR=0.653, p=0.04*, CI=0.436-0.977) and somatic complaints (OR=0.619, p=0.01*, CI=0.430-0.889) significantly protect against bullying behavior.
    DISCUSSIONS: Recognizing factors associated with bullying behavior, in particular factors distinctive to the local population, facilitates in strategizing effective interventions for school bullying among young adolescents in Malaysian schools.

    OBJECTIVE: Most weight interventions among patients with severe mental illness (SMI) used body mass index (BMI) as outcome measure but excluded waist circumference (WC) although the latter is a stronger predictor of obesity complications. This study aimed to assess a weight-management program consisting of education, exercise and behavioural techniques for patients with SMI using weight parameters including WC as the outcome measures.
    METHODS: A group intervention was carried out as part of psychiatric outpatient community service. It used structured modules on diet, exercise and related topics comprising of education and exercises sessions with a total of 12-week duration. The participants were outpatients with SMI recruited through referrals to the program by the treating doctor. The participants' body weight, BMI and WC were measured at the baseline, fortnightly and at the end of the program.
    RESULTS: A total of 27 patients participated in the program which was carried out in 6 cycles. The pre- and post-intervention comparisons analysis of the weight parameters found a significant reduction in the WC (mean=3.878 cm+5.165, p=0.001) while no significant changes were recorded in body weight and BMI.
    CONCLUSION: Small but significant loss in WC and possibly weight maintenance were achieved using this non-pharmacological intervention. Modest loss in WC may have an impact on reducing the risk of obesity-related health risks.

    BACKGROUND: Vaccine hesitancy is a complex behaviour which involves various degrees of indecision about specific vaccines or vaccination uptake. Access to antenatal care had been associated with positive vaccine behavior.

    OBJECTIVE: To determine the prevalence of vaccine hesitancy towards childhood immunisation amongst urban pregnant mothers and the associated socio-demographic factors.

    METHODS: A cross-sectional study was conducted among 1081 women who received antenatal care at a teaching hospital in Kuala Lumpur. Vaccine hesitancy was assessed using the Parent Attitudes about Childhood Vaccines (PACV) Survey in both English and validated Malay versions. The sociodemographic data of the mothers and their partners, source of vaccine information and reasons for hesitancy were analysed.

    RESULTS: Eighty-six (8.0%) pregnant mothers were vaccine hesitant. Ethnicity, religion, number of children, educational level and employment status were significantly associated with vaccine hesitancy. Multivariable analysis showed that a low level of education was the most significant risk factor (p

    BACKGROUND: This study aimed to identify the factors of CAM usage for general health and to determine the factors associated with the usage of different types of CAM after the diagnosis of chronic diseases among The Malaysian Cohort participants.
    METHODS: This was a cross-sectional study derived from The Malaysian Cohort (TMC) project, a prospective population-based cohort aged between 35 to 65 years old that recruited from April 2006 to September 2012. Association between the CAM usage and contributing factors were determined via logistic regression.
    RESULTS: The sample were mostly female (58.1%), Malays (43.1%), came from urban (71.9%), aged 44 years and below (26.8%) and had secondary education (45.9%). The prevalence of CAM usage varied across diseases; 62.8% in cancer patients, 53.3% in hypercholesterolemia, 49.4% in hypertensives and 48.6% in diabetics. General CAM usage was greater among female (OR: 1.54, 95% CI: 1.49, 1.59), Chinese (OR: 1.15, 95% CI: 1.12, 1.19), those with higher education (OR: 3.12, 95% CI: 3.00, 3.25), urban residents (OR: 1.55, 95% CI: 1.50, 1.61) and older people (OR ranging from 1.15 to 1.75) while for post-diagnosis of chronic diseases usage, the odds were higher among those with lower education and living in rural areas.
    CONCLUSION: Health status, educational level, age, living location and types of chronic diseases were significant factors that influence CAM usage for the intent of either health maintenance or disease treatment. Further exploration on CAM safety and benefit are crucial to minimize the adverse effect and to ensure the efficacy of CAM product.

    The use of traditional medicines is common among patients with chronic illnesses and this practice might pose health risks. The use among Libyan patients with diabetes is unknown. Therefore, this study aimed to estimate the prevalence of traditional medicine use in the previous year among Libyans with type 2 diabetes and to examine the association between its use and sociodemographic and clinical characteristics of the patients. A cross-sectional study was conducted at a large diabetes centre in Tripoli. A self-reported questionnaire was used for data collection. Of the 523 respondents, 28.9% used traditional remedies. Sex was the only variable significantly associated with traditional medicine use; more women used traditional medicines (P = 0.01). A total of 77 traditional medicine items were reported to be used, of which herbs were the most common. The use of traditional medicine for diabetes is prevalent and some of the reported items could pose health risks. Health education programmes are suggested to raise the awareness of the health risks of this practice.

    PURPOSE: This study aimed to determine the urethral stricture (US) rate and identify clinical and surgical risk factors associated with US occurrence after transurethral resection of the prostate using the bipolar Gyrus PlasmaKinetic Tissue Management System (PK-TURP).

    MATERIALS AND METHODS: This was an age-matched case-control study of US occurrence after PK-TURP. Retrospective data were collected from the hospital records of patients who had a minimum of 36 months of follow-up information. Among the data collected for analysis were prostate-specific antigen level, estimated prostate weight, the amount of prostate resected, operative time, history of urinary tract infection, previous transurethral resection of the prostate, and whether the PK-TURP was combined with other endourological procedures. The resection rate was calculated from the collected data. Univariate and multivariate analyses were performed to identify clinical and surgical risk factors related to US formation.

    RESULTS: A total of 373 patients underwent PK-TURP between 2003 and 2009. There were 13 cases of US (3.5%), and most of them (10 of 13, 76.9%) presented within 24 months of surgery. Most of the US cases (11 of 13, 84.6%) occurred at the bulbar urethra. Multivariable logistic regression analyses identified slow resection rate as the only risk factor significantly associated with US occurrence.

    CONCLUSIONS: The US rate of 3.5% after PK-TURP in this study is comparable to contemporary series. A slow resection rate seems to be related to US occurrence. This should be confirmed by further studies; meanwhile, we must be mindful of this possibility when operating with the PK-TURP system.

    Purpose: Older people often have chronic diseases which require a continuity of care over the long term. Countries undergoing population aging need to ensure that older people are receiving the care they need. This study assesses the prevalence of, reasons for, and factors associated with unmet healthcare needs among older people individuals in Malaysia.

    Patients and Methods: This cross-sectional study used data collected during 2018-2020 from 1204 older adults aged 60 and older selected from Selangor state, Malaysia. A comprehensive face-to-face interview based on the Bahasa Malaysia version of the Japan Gerontological Evaluation Study (JAGES-BM) questionnaire was administered to gain information on unmet healthcare needs, socioeconomic factors, health-related factors, and measures of function (activities of daily living, depression, visual impairment, hearing impairment, memory impairment, and walking impairment). Multivariate logistic regression was used to analyze factors associated with their unmet healthcare needs.

    Results: Overall, the percentage of older people respondents with unmet healthcare needs is 6.6%. The most reported reasons for forgoing or delaying healthcare were lack of knowledge about healthcare and financial barriers to care. The inability to travel alone (adjusted odds ratio [aOR] 2.51), being overweight (aOR 1.88), and having self-reported depression (aOR 2.23) were each associated with a higher likelihood of having unmet healthcare needs in their daily life.

    Conclusion: The prevalence of unmet healthcare needs among older people in this part of Malaysia is lower than that reported in some other countries. However, it is possible to further reduce unmet healthcare needs by improving people's knowledge and attitudes about appropriate healthcare utilization, strengthening financial protection measures and providing support to people at high risk of having unmet healthcare needs.

    This study aimed to assess the risk factors for gastric cancer in Yemen. A hospital-based case-control study of 70 cases and 140 controls was carried out in Sana'a city between May and October 2014. A structured questionnaire was used to collect information through direct interview. Living in rural areas, tobacco chewing and drinking untreated water were significant risk factors for gastric cancer. Frequent consumption of chicken, cheese, milk, starchy vegetables, cucumber, carrots, leeks, sweet pepper, fruit drinks, legumes and olive oil were associated significantly with decreased risk of gastric cancer. Multiple logistic regression analysis showed that chewing tobacco and frequent consumption of white bread were associated with increased risk of gastric cancer, whereas frequent consumption of chicken, cooked potatoes and fruit drinks had an inverse association. Risk of gastric cancer can be prevented by health education and increasing community awareness.

    BACKGROUND: Turner Syndrome (TS) is a rare sex chromosome abnormality occurring in 1 in 2500 female live births. To date, there is limited data on TS patients in Malaysia. This study aimed to investigate the quality of life (QoL) and body image disturbances among adult population with TS in comparison to age-matched controls in a tertiary hospital in Kuala Lumpur: Hospital Chancellor Tuanku Mukhriz, Universiti Kebangsaan Malaysia (HCTM, UKM).

    METHODS: This was a cross-sectional study carried out in HCTM, UKM, Kuala Lumpur. TS participants who attended clinic in HCTM, UKM and controls who were hospital staff members were recruited via purposive sampling. TS participants' sociodemographic and clinical profiles were retrieved from medical records. Two validated, translated questionnaires; World Health Organization Quality of Life (WHOQOL-BREF) questionnaire and Body Image Disturbances Questionnaires (BIDQ) were completed by participants.

    RESULTS: A total of 34 TS patients were approached and 24 (70.5%) of them participated in this study. Their median (IQR) age was 24.0 (7.0) years and their responses were compared to 60 age-matched healthy females as controls [median age (IQR) = 24.0 (8.0) years]. The most common medical problem in TS participants was premature ovarian insufficiency (n = 23; 95.8%). There were no significant differences between TS and control groups' median scores (overall QOL; 4.00 vs. 4.00, general health; 3.50 vs. 4.00, physical health; 14.86 vs. 15.43, psychological health; 14.67 vs. 14.00 and environment; 15.00 vs. 15.50) of the different WHOQOL-BREF domains. However, TS participants were found to score 13.33 against 16.00, lower than the control group (p

    INTRODUCTION: Thyroid carcinoma is classically diagnosed based on certain histological criteria. In some cases, definitive diagnoses may be challenging when morphological features are equivocal. This study evaluated the usefulness of Cytokeratin 19 (CK 19) as an immunohistochemical marker to differentiate the different histological types of malignant thyroid neoplasms, particularly papillary thyroid carcinoma (PTC) from benign thyroid lesions.

    MATERIALS AND METHODS: We collected 54 malignant and 65 benign thyroid lesions diagnosed by histology in Universiti Kebangsaan Malaysia Medical Centre between January 2010 and December 2015. All cases were immunohistochemically stained with CK 19 and evaluated by 3 independent observers. The immunostaining patterns were scored based on the intensity and proportion of staining and finally graded as negative, weak positive, moderate positive or strong positive. In addition, the immunostaining scores of the malignant cases were correlated with their TNM pathological tumour stages.

    RESULTS: Cytokeratin 19 staining expression was higher in malignant than benign thyroid lesions (p < 0.001) which was most prominent among classical PTC. The four PTC cases that showed negative or weak staining were all follicular variant of PTC. Benign conditions were mostly negative or showed weak positivity. There was no correlation between CK 19 expression and TNM primary tumour stage (pT).

    CONCLUSION: Cytokeratin 19 is a useful marker in differentiating malignant from benign thyroid conditions particularly the classical PTC, provided its interpretation is by correlation with morphology and takes into consideration the intensity and proportion of positive staining.

    BACKGROUND: Chronic kidney disease has become a major health problem around the world. It displays no symptoms until the later stages. Therefore, its early detection is crucial, and a suitable intervention is necessary to halt its development. The aim of this study was to develop and validate a recently formulated Chronic Kidney Disease Perception Scale (CKDPS) for diabetic patients based on Social Psychology, and their perceptions based on the Health Belief Model (HBM).

    METHODS: The newly developed CKDPS instrument was tested on 300 patients with diabetes mellitus in a cross-sectional study. The number of domains, model-fit index, construct validity, and internal consistency of this instrument were determined using exploratory (EFA) and confirmatory factor analysis (CFA).

    RESULTS: The EFA yielded nine domains: illness identity, timeline motivation, medical practice and co-operation for Social Psychology, and perceived benefit, perceived barriers, perceived susceptibility, perceived severity, and perceived cue to action for HBM. Four items with low factor loading were removed. CFA yielded the following fit indices for Social Psychology: the goodness of fit index (GFI) = 0.889, comparative fit index (CFI) = 0.934, root mean square error of approximation (RMSEA) = 0.053, normed chi-square (NC) = 1.831; and the following for HBM: GFI = 0.834, CFI = 0.957, RMSEA = 0.053, NC = 1.830. Values of Cronbach's α ranged between 0.760 and 0.909.

    CONCLUSIONS: The CKDPS includes 61 questions across nine domains, divided under two categories of Social Psychology and HBM. It is also a valid and reliable tool for measuring diabetic patients' perception of CKD prevention that can be used in larger studies.
