This study assessed the level of public awareness pertaining to risk factors, symptoms, treatment and source of information in relation to stroke and transient schaemic attack. Stroke risk profile of the respondents was correlated with their level of knowledge. Using a validated pre-tested questionnaire, 112 respondents were recruited during two separate community events. Respondents completed the questionnaire and underwent health screening. The data were analysed using SPSS version 20. Overall knowledge was poor. Only 35% of the respondents had satisfactory knowledge of the warning signs (p= 0.94) and 29% had satisfactory knowledge on the risk factors (p=0.46). When analysed according to risk groups, 26%, 30% and 41% of respondents had satisfactory awareness in the low, intermediate and high risk group, respectively. None of the respondents knew about the availability of treatment of acute stroke in the emergency department or the importance of rehabilitation as part of stroke management. Public awareness on stroke risk factors, symptoms and management is poor.
The aim of this study was to investigate the prevalence of postnatal urinary incontinence (PNUI), the risk factors associated with it and postnatal women’s (PN) level of engagement in practicing traditional Malay confinement care (TMCC) in Kelantan, Malaysia. A cross-sectional survey was conducted among 362 postnatal women aged between 18 – 45 years and who were between three to five months post-delivery. Participants were selected through convenience sampling at six Maternal and Child Health Clinics located in comparatively similar districts. Descriptive and inferential analyses including, factor analysis, Pearson chi-square, Mann-Whitney U test and logistic regressions analysis were used for data analysis. Overall, PNUI was reported by 80 women (22.1%). Vaginal delivery was associated with PNUI. All PN women within the study context practiced TMCC. The findings revealed that women who had PNUI were more likely to engage in a higher level of the ‘Body care’ component of TMCC. UI is prevalent among PN women in Kelantan, Malaysia. Further research into the impact of the ‘body care’ component of TMCC on PNUI is required.
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzyme deficiency worldwide including Malaysia. Screening of cord blood for partial G6PD deficiency is important as they are also prone to develop acute haemolysis. In this study, we determined the prevalence of partial G6PD deficient in paediatric population aged 1 month-12 years and normal term female neonates using OSMMR-D kit with haemoglobin (Hb) normalization and compare it with florescence spot test (FST). A total of 236 children, aged between between 1 month-12 years and 614 normal term female neonates were recruited for this study. Determination of normal means for G6PD activity and; cut-off points for partial and severe deficiency were determined according to WHO Working Group (1989). Determination of prevalence for partial deficiency for both groups (female patient) was done using this enzyme assay kit and findings were compared with FST. In this study, 15.7% (18/115) female children were classified as partial G6PD deficient by quantitative enzyme method (G6PD activity: 4.23-5.26U/gHb). However, FST only detected 0.9% (1/115) with minimal G6PD activity. The prevalence of partial G6PD deficiency in female neonate group was 3.42% (21/614) by enzyme assay versus 0.49% (3/614) by FST. This study concluded that our routine screening method using FST was unable to diagnose female heterozygotes. We recommend using this quantitative enzyme assay method by OSMMR-D kit since it was more sensitive in detecting G6PD deficiency in female neonates compared to FST.
Osteoporosis dikenali sebagai penyakit senyap kerana tidak mempunyai tanda-tanda awal. Ini disebabkan oleh kepadatan tulang yang berkurangan secara perlahanlahan seiring dengan peningkatan usia. Insiden penyakit ini semakin meningkat setiap tahun di seluruh dunia. Mengukur ketumpatan mineral tulang (BMD) menggunakan densitometry tulang konvensional (DXA) adalah praktikal dalam diagnosis osteoporosis tetapi kosnya adalah tinggi dan tidak dapat dilaksanakan dalam masyarakat. Untuk mengukur ketumpatan tulang, “quantitative ultrasound” (QUS) adalah teknik yang agak moden untuk diagnosis osteoporosis. Ianya agak mudah, konsisten, lebih murah dan kaedah yang selamat berbanding dengan teknik densitometry yang lain. Kedua-dua parameter QUS yang diukur pada masa kini adalah ultrasound jalur pengecilan (BUA) dan kelajuan bunyi (SOS). QUS juga dapat menjangka risiko patah. Ianya kini digunakan untuk memantau tindakbalas kepada rawatan anti-osteoporosis. Kajian in-vitro menunjukkan bahawa indeks QUS berhubungkait dengan BMD, bentuk tulang mikro dan parameter mekanikal. Oleh yang demikian, QUS berupaya untuk menjadi teknik baru untuk penilaian tulang.
Malaysia is a tropical country in the heart of south east Asia with a population of 24 million people of diverse ethnic, cultural and religious backgrounds living in harmony in 330,000 km(2) of land on the Asian mainland and Borneo. Malaysia, which lies on the crossroads of trade between east and west Asia, has an ancient history as a centre of trading attracting commerce between Europe, west Asia, India and China. It has had influences from major powers that dominated the region throughout its history. Today the country, after independence in 1957, has embarked on an ambitious development project to make it a developed country by 2020. In this effort the economy has changed from one producing raw material to one manufacturing consumer goods and services and the colonial health system has been overhauled and social systems strengthened to provide better services for its people. The per capita income, which was under 1,000 US dollars at independence, has now passed 4,000 US dollars and continues to grow, with the economy largely based on strong exports that amount to over 100 billion US dollars. The mental health system that was based on institutional care in four mental hospitals at independence from British colonial rule in 1957 with no Malaysian psychiatrists is today largely based on over 30 general hospital psychiatric units spread throughout the country. With three local postgraduate training programmes in psychiatry and 12 undergraduate departments of psychiatry in the country--all started after independence--there is now a healthy development of mental health services. This is being supplemented by a newly established primary care mental health service that covers community mental health by integrating mental health into primary health care. Mental health care at the level of psychiatrists rests with about 140 psychiatrists most of whom had undertaken a four-year masters course in postgraduate psychiatry in Malaysia since 1973. However, there continues to be severe shortages of other professionals such as clinical psychologists and social workers in mental health services. There are a few specialists, and specialized services in child, adolescent, forensic, rehabilitative, liaison or research fields of mental health. In the area of services for women and children, as well as the disabled in the community, there are strong efforts to improve the care and provide services that are in keeping with a caring society. New legislation on these are being passed every year and the setting up of a Ministry for Women's Affairs is one such move in recent years. Mental health in Malaysia has been slow in developing but has in the past decade seen important strides to bring it on par with other branches of medicine.

To assess the progression of dental caries among Malaysian infantry soldiers after 5 years in military service. A retrospective cohort study with a self-administered questionnaire and a clinical oral examination. Data were available for 173 (67.3%) soldiers. Mean decayed, missing, or filled teeth had increased significantly by 20.6% (P = .001) over 5 years. The highest increase was in the missing teeth component (+120%), followed by filled teeth (+23%). This was accompanied by a decrease in decayed teeth (-23.5%; P < .05). In terms of surfaces, mean decayed, missing, or filled surfaces, missing surfaces, and filled surfaces had increased significantly (P < .05). Caries experience was significantly associated with smoking status and rank (P < .05). Dental caries experience was worse after 5 years in military service compared with during recruitment, and there were more tooth extractions than restorations. Health promotion interventions are needed to prevent further tooth loss among soldiers.

The aim of this 5-year longitudinal cohort study was to assess the prevalence, severity, and trends in caries increment and impact of the School Dental Incremental Care Programme (SDICP). Data were gathered from school dental records as part of the SDICP. A sample of 1830 children were included and checked for caries experience annually using World Health Organization criteria. In total, 95.4% of the children were caries free in 2004, and caries experience declined to 70.5% in 2009 with an average of 4.9% annually. At baseline, the mean DMFT (confidence interval [CI]) was 0.06 (0.05-0.08) and increased to 0.58 (0.53-0.63) in 2009. Children with active caries were 4.4% in 2004, and figures rose to 9.6% in 2009. The FT component increased most rapidly during these 5 years from 0.2% to 25.1%. Overall caries prevalence and increment was low in this study. Proportions of FT component were higher as compared with DT component with low rate of extractions during the latter years of the study.

Previous cytotoxic (anticancer) evaluations ofElephantopus molliswere mainly focused on its elephantopin derivatives neglecting the combined effect of the phytochemicals in its traditionally used extracts. In this study, the cytotoxic mechanism of its extracts was investigated using methylene blue assay. The cytotoxic screening results revealed the ethyl acetate extract as the most potent extract by displaying prominent dose-dependent and time-dependent growth inhibitions in human liver carcinoma HepG2 cells with the lowest EC50value of 9.38 ± 0.43 µg/mL after 72 hours of treatment. Acute exposure of the HepG2 cells to the ethyl acetate extract produced a significant regulation of caspase-3 with the peak expression at 8 hours of treatment (P< .05). DNA fragmentation indicated by DeadEnd Apoptosis Detection System-labeled nuclei cells confirmed that the extract induced apoptotic cell death through caspase-3-dependent pathway in HepG2 cells.
OBJECTIVE: To describe the health-related quality of life (HRQoL) profile of hypertensive population in Pakistan.
METHODS: A cross-sectional descriptive study was undertaken with a cohort of 385 hypertensive patients attending two public hospitals in Quetta city, Pakistan. The EuroQoL EQ-5D scale was used for the assessment of HRQoL. EQ-5D is a standardized instrument for use as a measure of health outcome and is used in the clinical and economic evaluation of health care as well as population health surveys. The HRQoL was scored using values derived from the UK general population survey. P ≤ 0.05 was taken as significant.
RESULTS: Two hundred and sixty-five (68.85%) respondents were men with 3.01 ± 0.939 years of history of hypertension. Majority (n = 186, 48.3%) were categorized in age group of 28-37 years with mean age of 39.02 ± 6.596. Education, income and locality had significant relation with HRQoL score. HRQoL was measured poor in our study patients (0.4674 ± 0.2844).
CONCLUSION: Hypertension has an adverse effect on patients' well-being and HRQoL. Results from this study could be useful in clinical practice, particularly in early treatment of hypertension, at point where improving HRQoL is still possible.

This study aims to determine the prevalence and associated factors of noise-induced hearing loss (NIHL) among vector control workers in the state of Negeri Sembilan, Malaysia. This was an analytical cross-sectional study conducted on 181 vector control workers who were working in district health offices in a state in Malaysia. Data were collected using a self-administered questionnaire and audiometry. Prevalence of NIHL was 26% among this group of workers. NIHL was significantly associated with the age-group of 40 years and older, length of service of 10 or more years, current occupational noise exposure, listening to loud music, history of firearms use, and history of mumps/measles infection. Following logistic regression, age of more than 40 years and noise exposure in current occupation were associated with NIHL with an odds ratio of 3.45 (95% confidence interval = 1.68-7.07) and 6.87 (95% confidence interval = 1.54-30.69), respectively, among this group of vector control workers.
In the field of cell-based therapy and regenerative medicine, clinical application is the ultimate goal. However, one major concern is: does in vitro manipulation during culture expansion increases tumourigenicity risk on the prepared cells? Therefore, the aim of this study was to investigate the effect of long-term in vitro expansion on human adipose-derived stem cells (ASCs). The ASCs were harvested from lipo-aspirate samples and cultured until passage 20 (P20), using standard culture procedures. ASCs at P5, P10, P15 and P20 were analysed for morphological changes, DNA damage (Comet assay), tumour suppressor gene expression level (quantitative PCR), p53 mutation, telomerase activity, telomere length determination and in vivo tumourigenicity test. Our data showed that ASCs lost their fibroblastic feature in long-term culture. The population doubling time of ASCs increased with long-term culture especially at P15 and P20. There was an increase in DNA damage at later passages (P15 and P20). No significant changes were observed in both p53 and p21 genes expression throughout the long-term culture. There was also no p53 mutation detected and no significant changes were recorded in the relative telomerase activity (RTA) and mean telomere length (TRF) in ASCs at all passages. In vivo implantation of ASCs at P15 and P20 into the nude mice did not result in tumour formation after 4 months. The data showed that ASCs have low risk of tumourigenicity up to P20, with a total population doubling of 42 times. This indicates that adipose tissue should be a safe source of stem cells for cell-based therapy.

4-Chloro-1,2-phenylenediamine (4-Cl-o-PD) is a halogenated aromatic diamine that was used as a precursor for manufacturing permanent hair dyes. Despite its well-documented mutagenic and carcinogenic effects in a number of in vitro and in vivo models, its cytotoxicity and mode of action have not received similar attention. Here, we investigated the effect of 4-Cl-o-PD on Mardin-Darby canine kidney cells. It induced apoptosis and the evidence suggests its initiation by reactive oxygen species (ROS). The results of various assays used show a dose-dependent (i) decrease in cell viability, (ii) increase in cells at sub-G1 phase and the G0/G1 phase arrested in cell cycle, (iii) increase in intracellular ROS accompanied by depletion of glutathione, and (iv) that apoptotic cell death probably involves activation of both intrinsic and extrinsic pathways.
Oral Candida colonisation is higher in tobacco smokers as compared to non-smokers; however, it remains unknown whether smokeless tobacco chewers are susceptible to increased oral Candida colonisation. The aim was to determine the oral Candida carriage and species prevalence amongst habitual gutka-chewers and non-chewers in a cohort from Karachi, Pakistan. Forty-five gutka-chewers and 45 non-chewers were included. Information regarding age, sex, duration of gutka-chewing habit, daily frequency of gutka consumption, duration of holding gutka in the mouth, daily frequency of tooth-brushing and tongue brushing was collected using a questionnaire. Oral yeast samples were collected by scraping the dorsum of the tongue and bilateral buccal mucosa with a sterile cotton swab. Identification of yeast species was performed using standard techniques. Tongue lesions were identified and recorded. Unstimulated whole salivary flow rate (UWSFR) was also measured. There was no significant difference in the mean age, UWSFR and oral Candida carriage among gutka-chewers and non-chewers. Individuals were chewing gutka since 4·4 years and were consuming five gutka sachets daily. Candida albicans (C. albicans) was the most common yeast species isolated from 57·8% gutka-chewers and 64.4% non-chewers. In 24.4% gutka-chewers and 22·2% non-chewers, two candidal strains (C. albicans and Candida tropicalis) were isolated. In conclusion, the present results indicated no significant difference in oral Candida carriage in habitual gutka-chewers and non-chewers.
A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering in 20 adult palliative care inpatients of University Malaya Medical Centre. The results were thematically analyzed. Ten basic themes were generated (1) loss and change → differential suffering, (2) care dependence → dependent suffering, (3) family stress → empathic suffering, (4) disease and dying → terminal suffering, (5) health care staff encounters → interactional suffering, (6) hospital environment → environmental suffering, (7) physical symptoms → sensory suffering, (8) emotional reactions → emotional suffering, (9) cognitive reactions → cognitive suffering, and (10) spiritual reactions → spiritual suffering. An existential-experiential model of suffering was conceptualized from the analysis. This model may inform the development of interventions in the prevention and management of suffering.

The need for orthodontic treatment is increasing all the time. As the treatment is time consuming ranging from a year to several years, any method of reducing the period of treatment and increasing the quality of the tissue will be beneficial to patients. The use of non-invasive techniques such as low level laser therapy and low intensity pulsed ultasound in accelerating orthodontic tooth movement are promising. Thus, this overview study will help to generate more understanding about the background information and the possible applications of them in daily orthodontics, depending on previous literature searching for reviews and original research articles.
Demand and use for oral health-related quality of life (OHRQoL) instruments have increased in recent years in both research and clinical settings. These instruments can be used to measure patient's health status or detect changes in a patient's health status in response to an intervention or changes in disease trajectory. Ensuring universal acceptance of these measures requires easy interpretation of its scores for clinicians, researchers, and patients. The most important way of describing and interpreting this significance of changes in OHRQoL is through the establishment of minimal important difference (MID). The minimally important difference represents the smallest improvement considered worthwhile by a patient. A comprehensive search of published literature identified only 12 published articles on establishment of MID for OHRQoL measures. This scarcity of published studies on MID encourages the need of appropriate interpretation and describing patient satisfaction in reference to that treatment using MID. Anchor- and distribution-based methods are the two general approaches that have been proposed and recommended to interpret differences or changes in OHRQoL. Both of these methods of determining the MID have specific shortcomings; therefore, it is proposed to adopt triangulation approaches in which the methods are combined. The objective of this review is to summarize the need for, importance of, and recommendations for methods of establishing MID for OHRQoL measures.
