    Hepatocellular carcinoma (HCC) is the most common primary liver cancer and its diagnosis on routine stains is usually straightforward, except in some cases where there may be difficulty in distinguishing HCCs from metastatic carcinomas (MC) and cholangiocarcinomas (CC). Hepatocyte Paraffin 1 antibody (Hep Par 1) is a new monoclonal antibody which reacts with normal and neoplastic hepatocytes, and this study aims to determine its specificity and sensitivity in distinguishing hepatocellular carcinoma (HCC) from cholangiocarcinoma (CC) and metastatic carcinomas (MC). Hep Par 1 antibody was applied to 28 cases of HCC, 22 cases of MC from varying sites and 8 CCs, and produced a strong, diffuse, granular, cytoplasmic staining of all benign hepatocytes. 23 out of 28 cases of HCC showed heterogeneously positive staining for Hep Par 1 irrespective of their degree of differentiation, while 2 out of 8 cases of cholangiocarcinoma were positive for Hep Par 1, and all 22 cases of metastatic carcinoma were negative. The sensitivity and specificity of Hep Par 1 for HCC was 82.1% and 93.3% respectively; whereby the antibody was noted to show occasional false positivity in cases of cholangiocarcinoma and non-neoplastic bowel mucosa, while its variable staining in HCC produced false negative results in some small biopsies. Thus, Hep Par 1 should be used in a panel with other antibodies to obtain useful information in distinguishing HCC from CC and MC.

    Our aim of this study was to develop a new methodology for constructing a bilayer human skin equivalent to create a more clinical compliance skin graft composite for the treatment of various skin defects. We utilized human plasma derived fibrin as the scaffold for the development of a living bilayer human skin equivalent: fibrin-fibroblast and fibrin-keratinocyte (B-FF/FK SE). Skin cells from six consented patients were culture-expanded to passage 1. For B-FF/FK SE formation, human fibroblasts were embedded in human fibrin matrix and subsequently another layer of human keratinocytes in human fibrin matrix was stacked on top. The B-FF/FK SE was then transplanted to athymic mice model for 4 weeks to evaluate its regeneration and clinical performance. The in vivo B-FF/FK SE has similar properties as native human skin by histological analysis and expression of basal Keratin 14 gene in the epidermal layer and Collagen type I gene in the dermal layer. Electron microscopy analysis of in vivo B-FF/FK SE showed well-formed and continuous epidermal-dermal junction. We have successfully developed a technique to engineer living bilayer human skin equivalent using human fibrin matrix. The utilization of culture-expanded human skin cells and fibrin matrix from human blood will allow a fully autologous human skin equivalent construction.

    This study was to assess collagen type II and collagen type I gene expression in tissue-engineered human auricular: cartilage formed via tissue engineering technique. Large-scale culture expansions were transformed into 3D in vitro construct and were implanted subcutaneously on the dorsal of athymic mice. After 8 weeks, explanted construct was processed in the same manner of native cartilage to facilitate cells for gene expression analysis. Isolated cells from in vivo construct demonstrated expression of type II collagen gene comparable to native cartilage. This study verified that tissue-engineered auricular cartilage expressed cartilage specific gene, collagen type II after in vivo maturation.

    To date there is no optimal approach to reconstruct an external ear. However, advances in tissue engineering technologies have indicated that in vitro autologous elastic cartilage might be of great importance in the future treatment of these patients. The aim of this study was to observe monolayer expansion of auricular cartilage and to evaluate engineered cartilage using standard histochemical study.

    Our objective is to determine the quality of tissue engineered human skin via immunostaining, RT-PCR and electron microscopy (SEM and TEM). Culture-expanded human keratinocytes and fibroblasts were used to construct bilayer tissue-engineered skin. The in vitro skin construct was cultured for 5 days and implanted on the dorsum of athymic mice for 30 days. Immunostaining of the in vivo skin construct appeared positive for monoclonal mouse anti-human cytokeratin, anti-human involucrin and anti-human collagen type I. RT-PCR analysis revealed loss of the expression for keratin type 1, 10 and 5 and re-expression of keratin type 14, the marker for basal keratinocytes cells in normal skin. SEM showed fibroblasts proliferating in the 5 days in vitro skin. TEM of the in vivo skin construct showed an active fibrocyte cell secreting dense collagen fibrils. We have successfully constructed bilayer tissue engineered human skin that has similar features to normal human skin.

    Autologous cells are usually preferred in treating damaged tissue to avoid risks of immunological rejection and transmitting infectious diseases. Since only limited amount of tissue can be obtained without causing morbidity at the donor site, in vitro expansion of isolated cell is essential in order to acquire sufficient number of cells to reconstruct neocartilage. The aim of this study was to examine whether serial expanded chondrocytes can be use to generate neocartilage in vivo.

    Cronkhite-Canada Syndrome (CCS) is a syndrome characterised by a constellation of signs including but not limited to onychodystrophy of the finger and toe nails, skin hyperpigmentation and alopecia. Endoscopic features showed hamartomatous polyps involving all segments of the gastrointestinal tract with the characteristic exception of being oesophageal sparring. These polyps show confirmation by the presence of eosinophils and mast cells at the lamina propria upon histological studies.

    OBJECTIVE: To determine the prevalence of urinary incontinence among primigravida in the third trimester, its risk factors and its effect to quality of life.

    STUDY DESIGN: This is a cross sectional study involving primigravida in their third trimester of pregnancy, who attended the Patient Assessment Centre of a tertiary referral hospital in Klang Valley from July 2012 to June 2013. The participants were chosen randomly using convenience sampling. A face-to-face interview and a review of their antenatal record were done by trained interviewers. Data on sociodemographic and risk factors were obtained followed by the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). The data was analysed using Statistical Package for Social Science version 20.0.

    RESULTS: A total of 306 women were involved. The prevalence of urinary incontinence during third trimester was 34.3% (95%CI: 29.0, 39.7). Stress incontinence (64.8%) is the commonest followed by mixed incontinence (24.8%) and urge incontinence (6.7%). Childhood enuresis (p=0.003) and previous history of urinary incontinence (p<0.001) were significantly associated with urinary incontinence. More than 50 percent of women with urinary incontinence in the third trimester felt that it did not affect their daily activities at all. Only 10% of women felt greatly affected by this problem.

    CONCLUSION: Urinary incontinence is not uncommon among primigravida however many women did not feel that it affected their quality of life. Childhood enuresis and history of urinary incontinence were proven risk factors.

    Three cases of diffuse panbronchiolitis (DPB) occurring in two Malaysian Chinese patients and one Malay patient are reported. They had similar clinical, radiological and physiological features which are characteristic of DPB. The diagnosis in one of the cases was confirmed histologically by transbronchial lung biopsy. These could be the first three cases identified in Malaysia.

    Introduction: The Patient Activation Measure (PAM) is one of the most extensively used, widely translated, and tested instruments worldwide in measuring patient activation levels in self-management. This study aimed to determine the validity and reliability of the PAM-13 Malay version among patients with Metabolic Syndrome (MetS) attending a primary care clinic.
    Methods: This work is a cross-sectional validation study among patients with MetS attending a university primary care clinic in Selangor. The PAM-13 Malay version underwent a validation process and field testing. Psychometric properties were examined using principal component analysis (PCA) with varimax rotation, scree plot, Monte Carlo simulation, internal consistency, and test-retest reliability analyses.
    Results: The content of the PAM-13 Malay version and the original version were conceptually equivalent. The questionnaire was refined after face validation by 10 patients with MetS. The refined version was then field-tested among 130 participants (response rate 89.7%). The Kaiser-Meyer-Olkin test was 0.767, and Bartlett's test of sphericity was ≤0.001, indicating sampling adequacy. Two factors were identified and labeled as (1) Passive and Building Knowledge, and (2) Taking Action and Maintaining Behavior. These labels were chosen as they were conceptually consistent with the items representing the levels of activation in PAM-13. The validated PAM-13 Malay version consisted of 13 items, framed into two domains. The overall Cronbach's α was 0.79, and the intraclass correlation coefficient was 0.45.
    Conclusions: The PAM-13 Malay version is valid, reliable, and fairly stable over time. This questionnaire can be used to evaluate the levels of activation among patients with MetS in primary care in Malaysia.

    BACKGROUND: Offspring of type 2 diabetes patients have an absolute risk of 20-40% of developing the condition. Type 2 diabetes patients should be encouraged to speak to their offspring regarding diabetes risk and prevention strategies. The Health Belief Model conceptualises that the higher the perceived risk, the more likely an individual will modify their behaviour. The objectives of this study were to i) determine the distribution of type 2 diabetes patients regarding their willingness to accept training to speak to their offspring, ii) determine the distribution of type 2 diabetes patients regarding their willingness to accept training based on the HBM and iii) to determine the factors associated with their willingness to accept training.

    METHODS: This was a cross-sectional study amongst type 2 diabetes patients attending two primary care clinics in Malaysia. Sociodemographic data and knowledge of diabetes risk factors were collected. The adapted, translated and validated Diabetes Mellitus in the Offspring Questionnaire-Malay version (DMOQ-Malay) was self-administered. Statistical analysis included descriptive statistics, univariate and multiple logistic regression (MLogR).

    RESULTS: A total of 425 participants were recruited. Of these, 61.6% were willing to accept training. In MLogR, six variables were found to be significantly associated with willingness to accept training. These were i) positive family history [Adj. OR 2.06 (95% CI: 1.27, 3.35)], ii) having the correct knowledge that being overweight is a risk factor [Adj. OR 1.49 (95%CI: 1.01, 2.29)], iii) correctly identifying age ≥ 40 years old as a risk factor [Adj. OR 1.88 (95%CI: 1.22, 2.90)], iv) agreeing that speaking to their offspring would help them to prevent type 2 diabetes [Adj. OR 4.34 (95%: 1.07, 17.73)], v) being neutral with the statement 'I do not have much contact with my offspring' [Adj. OR: 0.31 (95% CI: 0.12, 0.810] and vi) being neutral with the statement 'my offspring are not open to advice from me' [Adj. OR: 0.63 (95% CI: 0.31, 0.84].

    CONCLUSION: The majority of type 2 diabetes patients were willing to accept training to speak to their offspring to prevent diabetes. A training module should be designed to enhance their knowledge, attitude and skills to become family health educators.

    Limited health literacy (HL) is linked to many negative health outcomes, including poor self-management of chronic diseases and medication adherence among patients. There are a lack of data regarding HL in the elderly population in Malaysia. This study aimed to determine the prevalence of limited HL levels and its associated factors among elderly patients in an urban academic primary care clinic in Selangor, Malaysia. A cross-sectional study was conducted among 413 elderly patients (≥60 years old) who attended this academic primary care clinic between January 2020 and January 2021. Sociodemographic data, clinical characteristics, and health literacy scores were collected. Descriptive statistics (median with interquartile ranges (IQR), frequency, and percentages) and multiple logistic regression were utilized. The prevalence of limited HL in our population was 19.1% (95% CI: 15.3, 23). The middle-old (70-79 years) and very-old (≥80 years) age groups were more likely to have limited HL (aOR 4.05; 95% CI: 2.19, 7.52 and aOR 4.36; 95% CI: 1.02, 18.63, respectively). Those with at least secondary school education (aOR 0.06; 95% CI: 0.02, 0.24) and those who found medical information via the internet/television (aOR 0.21; 95% CI: 0.05, 0.93) had lower odds of having limited HL. In conclusion, having limited HL levels was not common among elderly patients in this primary care clinic. Further studies involving rural and larger primary care clinics in Malaysia are required to support these findings.

    Objective: The aim of this study was to evaluate the psychometric properties of the Malay translated version of the Theory of Planned Behavior (TPB) intention to quit smoking questionnaire.
    Methods: A cross-sectional study was performed involving 185 male smokers. The forward-backward translation procedure was adopted to translate the questionnaire from English to Malay. The internal consistency and stability were assessed using Cronbach’s alpha and a correlation analysis and Exploratory Factor Analysis was conducted.
    Result: The translated questionnaire showed good internal consistency with Cronbach’s alpha values of 0.86, 0.64, 0.74 and 0.90 for each of the four respective factors. The test-retest reliability revealed acceptable stability, with Spearman’s correlation coefficients ranging from low to moderate (r>0.30-0.50) and a satisfactory inter class correlation coefficient (ICCs). The construct validity achieved an acceptable factor loading for each construct which ranged from 0.40 to 0.90.
    Conclusion: The current study provided
    psychometric evidence for an appropriate, reliable and valid tool of TPB Malay version. This questionnaire could be applied in evaluating smoking cessation interventions in Malaysia.

    BACKGROUND: Return to work is an important aspect for cardiac rehabilitation following a major cardiac event.

    OBJECTIVE: The aim was to understand the local prevalence and factors associated with returning to work in Malaysia after a cardiac event.

    METHODS: A cross sectional design was used. All patients attending the cardiac rehabilitation program after major cardiac event during an 11-months period (2011-2012) were included. Data relating to socio-demographic, work-related, risk factors and acute myocardial infarction were collected. The SF-36 questionnaire was used to assess quality of life. Regression analysis was used to determine the predicting factors to return to work.

    RESULTS: A total of 398 files were screened, 112 respondents agreed to participate giving a response rate of 47.3%. The prevalence of returned to work (RTW) was 66.1% [95% CI: 57.2-75.0]. Factors associated with work resumption were age (Adj. OR: 0.92 (95% CI: 0.84-0.99), diabetes mellitus (Adj. OR: 3.70, 95% CI: 1.35-10.12), Mental Component Summary (MCS) score (Adj. OR: 1.05 (95% CI: 1.01-1.09) and baseline angiography findings. Patients with single vessel and two vessel disease were 8.9 times and 3.78 times more likely to return to work compared to those with 3 vessels (Adj. OR: 8.90 (95% CI: 2.29-34.64) and Adj. OR: 3.78, (95% CI: 1.12, 12.74).

    CONCLUSIONS: We proposed a cardiac rehabilitation program to emphasize mental health as it may improve successful return to work after cardiac event.

    BACKGROUND: The Diabetes Mellitus in the Offspring Questionnaire (DMOQ) assesses the perceptions of Type 2 diabetes mellitus (T2DM) patients on the risk of their offspring developing T2DM and the possibility of intervention to reduce this risk. It has 34 items framed within seven domains. This study aimed to adapt, translate and validate the DMOQ from English into the Malay language.

    METHODS: This was a cross-sectional validation study among 159 T2DM patients attending a public primary care clinic in Selangor. The DMOQ English version underwent adaptation, translation, face validation and field testing to produce the Malay version. Psychometric analysis was performed using Exploratory Factor Analysis, internal consistency and testretest reliability.

    RESULTS: The DMOQ domains were conceptually equivalent between English and Malay language. A total of 13 items and two domains were removed during the validation process (three items during the content validation, three items due to poor factor loadings, five items as they loaded onto two domains which were not interpretable, one item as it did not fit conceptually into the factor it loaded onto and one openended question as it did not fit into the retained domains). Therefore, the final DMOQ Malay version consisted of 21- items within five domains. The Cronbach alpha was 0.714 and the intraclass-correlation coefficient was 0.868.

    CONCLUSION: The DMOQ Malay version is a valid and reliable tool which is consistent over time. It can be used to examine the perception of T2DM patients towards the risk of their offspring developing diabetes and possibility of intervention in Malay-speaking patients.

    Brain herniation is generally thought to be unlikely to occur in newborns due to the presence of the patent fontanelles and cranial sutures. A review of the literature published from 1993 to 2008 via MEDLINE search revealed no reports on neonatal brain herniation from intracranial tumour. We report a preterm Malay male infant born via elective Caesarean section for antenatally diagnosed intracerebral tumour, which subsequently developed herniation. Cerebral magnetic resonance imaging showed features that were compatible with a large complex intracranial tumour causing mass effect and gross hydrocephalus. Tumour excision was scheduled when the infant was two weeks old. Unfortunately, on the morning of the surgery, he developed signs of brain herniation and had profuse tumour haemorrhage during the attempted excision. Histopathological examination revealed an embryonal tumour, possibly an atypical rhabdoid/teratoid tumour. This case illustrates that intracranial tumours in newborns can herniate and should therefore be closely monitored.

    INTRODUCTION: Achieving optimal control of blood pressure is easier when those affected understand the risks and consequences of hypertension and the principles of management. It is particularly important in disadvantaged groups among whom blood pressure control is often poor. However, effective responses require evidence of the knowledge and beliefs of those affected. This was undertaken as part of a larger study of the therapeutic journeys followed by individuals living in B40 (bottom 40% by income) households in Malaysia, the Responsive and Equitable Health Systems-Partnership on Non- Communicable Diseases (RESPOND).This paper describes their reported knowledge of hypertension, health, and measures that can improve hypertensive control.

    MATERIALS AND METHODS: The communities were selected from rural and urban populations in four peninsular states (Selangor, Kelantan, Perak, and Johor). Following a multistage sampling approach, communities in each stratum were selected according to probability proportional to the size and identified based on national census data by the community and administrative registers. Households were randomly selected. Eligible individuals were those aged between 35 and 70 years old, self-reported or identified as hypertensive at screening. Informed consent was taken. A survey using validated questionnaires was conducted.

    RESULTS: The total number of respondents was 579. The mean age was 59.0 (95%: 58.4, 59.7) and more were women (71.5%) than men (28.5%). Regarding respondents selfreported level of hypertension knowledge, 2.9% reported having no knowledge at all, 80.1% had little knowledge, and 17.9% were very familiar. Among all respondents, 56.2% (95% CI: 50.7, 61.6) correctly answered at least four out of five objective knowledge questions.Almost all (91.5%) were aware that hypertension could cause a stroke. However, one-fifth believed it could cause cancer. Almost threequarters said that people with high blood pressure generally felt well (72.1%) and recognized that they should not stop taking their medication (70.7%). Most of the respondents knew that people should take their medication even if they feel well (73.6%). Although more than half (66.0%) of the respondents rated their health as poor. Interestingly, most did not perceive themselves as having a long-term illness (95.0%).

    CONCLUSION: This study provides reassurance that individuals with hypertension in disadvantaged communities in Malaysia have a relatively good understanding of hypertension. Further research should explore the challenges they face on their therapeutic journeys.
