    OBJECTIVES: To determine treatment outcomes and associated predictors of all patients registered in 2012 with the Malaysian National Tuberculosis (TB) Surveillance Registry.
    METHODS: Sociodemographic and clinical data were analysed. Unfavourable outcomes included treatment failure, transferred out and lost to follow-up, treatment defaulters, those not evaluated and all-cause mortality.
    RESULTS: In total, 21 582 patients were registered. The mean age was 42.36 ± 17.77 years, and 14.2% were non-Malaysians. The majority were new cases (93.6%). One fifth (21.5%) had unfavourable outcomes; of these, 46% died, 49% transferred out or defaulted and 1% failed treatment. Predictors of unfavourable outcomes were older age, male sex, foreign citizenship, lower education, no bacille Calmette-Guérin (BCG) vaccination scar, treatment in tertiary settings, smoking, previous anti-tuberculosis treatment, human immunodeficiency virus infection, not receiving directly observed treatment, advanced chest radiography findings, multidrug-resistant TB (MDR-TB) and extra-pulmonary TB. For all-cause mortality, predictors were similar except for rural dwelling and nationality (higher mortality among locals). Absence of BCG scar, previous treatment for TB and MDR-TB were not found to be predictors of all-cause mortality. Indigenous populations in East Malaysia had lower rates of unfavourable treatment outcomes.
    CONCLUSIONS: One fifth of TB patients had unfavourable outcomes. Intervention strategies should target those at increased risk of unfavourable outcomes and all-cause mortality.

    Echocardiography is essential for the diagnosis and management of infective endocarditis (IE). However, the reproducibility for the echocardiographic assessment of variables relevant to IE is unknown. Objectives of this study were: (1) To define the reproducibility for IE echocardiographic variables and (2) to describe a methodology for assessing quality in an observational cohort containing site-interpreted data. IE reproducibility was assessed on a subset of echocardiograms from subjects enrolled in the International Collaboration on Endocarditis registry. Specific echocardiographic case report forms were used. Intra-observer agreement was assessed from six site readers on ten randomly selected echocardiograms. Inter-observer agreement between sites and an echocardiography core laboratory was assessed on a separate random sample of 110 echocardiograms. Agreement was determined using intraclass correlation (ICC), coverage probability (CP), and limits of agreement for continuous variables and kappa statistics (κweighted) and CP for categorical variables. Intra-observer agreement for LVEF was excellent [ICC = 0.93 ± 0.1 and all pairwise differences for LVEF (CP) were within 10 %]. For IE categorical echocardiographic variables, intra-observer agreement was best for aortic abscess (κweighted = 1.0, CP = 1.0 for all readers). Highest inter-observer agreement for IE categorical echocardiographic variables was obtained for vegetation location (κweighted = 0.95; 95 % CI 0.92-0.99) and lowest agreement was found for vegetation mobility (κweighted = 0.69; 95 % CI 0.62-0.86). Moderate to excellent intra- and inter-observer agreement is observed for echocardiographic variables in the diagnostic assessment of IE. A pragmatic approach for determining echocardiographic data reproducibility in a large, multicentre, site interpreted observational cohort is feasible.

    BACKGROUND: Rat sarcoma virus mutational status guides first-line treatment in metastatic colorectal cancer. This study was a multi center, multi-country ambispective, observational study in the Middle East and North Africa assessing regional rat sarcoma virus testing practices in newly diagnosed patients.

    METHODS: The retrospective arm (2011-2014) included adults with metastatic colorectal cancer who had initiated first-line therapy with ≥1 post-baseline visit and survival data. The prospective arm (2014-2019) enrolled newly diagnosed patients with histologically proven metastatic colorectal cancer with ≥1 measurable lesion per Response Evaluation Criteria in Solid Tumors, and tissue availability for biomarker analysis. Data look-back and follow-up were 2 years; the rate of RAS mutation was evaluated.

    RESULTS: RAS testing was ordered for patients in retrospective (326/417) and prospective (407/500) studies. In the former, testing was typically prescribed after first-line treatment initiation, significantly more in patients with stage IV disease (P < .005), resulting in the addition of targeted therapy (41.8% anti-epidermal growth factor receptor, 30.2% anti-vascular endothelial growth factor) in wild-type metastatic colorectal cancer, and significantly impacted the treatment of left-sided tumors (P = .037). In the latter, 58.4% were RAS wild-type; 41.6% were RAS mutant. Non-prescription of RAS testing was attributed to test unavailability, financial, or medical rea sons; predictors of testing prescription were older age, primary tumor in ascending colon, and high tumor grade. RAS status knowledge resulted in the addition of anti-vascular endothelial growth factor (20.4%) or anti-epidermal growth factor receptor therapy (21.2%).

    CONCLUSION: Before 2014, RAS testing in patients with colorectal cancer in the Middle East and North Africa was often performed after first-line treatment. Testing is more routine in newly diagnosed patients, potentially shifting early treatment patterns.

    In this retrospective study, we investigated 263 foreign patients who were diagnosed as having tuberculosis at the National Tuberculosis Center (NTBC) from January 2001 to December 2002. The age range was 14-72 years, with a mean of 33.3 +/- 9.95 years. The study subjects were predominantly males (60%) and females comprised 40%, where the greater impact of tuberculosis was observed in the young and active ones (up to 34 years of age), than middle-age (up to 54). A significantly higher percentage of these patients were from the Southeast Asian countries (87%) and particularly occurred in single male (47.5%) and married female (71.4%) patients (p<0.05). We also found that tuberculosis was significantly higher in female (50.5%) and male (64%) with smoking laborers (p<0.05). Fever (70%), cough (90.5%) and BCG vaccination status showed a significantly higher percentage in male patients (p<0.05), whereas lymphadenopathy (22%) was found in a significantly higher percentage in females (p<0.05). Overall, pulmonary disease (94.3%) occurred more commonly in males and the pleura (3.2%) was the most common site of disseminated tuberculosis. By contrast, the lymph node (11.4%) and miliary (4.8%) forms were the more common extrapulmonary tuberculosis in females. More males had higher percentage of treatment completed at > or = 6 (38%) and > or = 9 (13.3%) months in pulmonary tuberculosis, whilst, more females showed higher percentage of treatment completed (8.7%) in extrapulmonary tuberculosis. Surprisingly, more women showed non-compliance to the anti-tubercular therapy than their counterpart in this study.

    Introduction: type 2 diabetes mellitus has become a global public health crisis. The increment in the cases has contributed significantly to the parallel increase in the prevalence of overweight and obesity. This paper aimed to analyse the relationship between lipid profile, waist circumference and body mass index (BMI) with the glycaemic control of the diabetes patients in Kedah.

    Methods: a cross-sectional study was conducted, using the Kedah audit samples data extracted from the National Diabetes Registry (NDR) from the year 2014 to 2018. A total of 25,062 registered type 2 diabetes mellitus patients were selected using the inclusion and exclusion criteria from the registry. Only patients with complete data on their HbA1C, lipid profile, waist circumference and BMI were analysed using SPSS version 21.

    Results: the means for the age, BMI and waist circumference of the samples were 61.5 (±10.85) years, 27.3 (±5.05) kg/m2 and 89.46 (±13.58) cm, respectively. Poor glycaemic control (HbA1c>6.5%) was observed in 72.7% of the patients, with females having poorer glycaemic control. The BMI and waist circumference were found to be significantly associated with glycaemic control (P<0.001). The total cholesterol, triglycerides and low-density lipoproteins values showed positive correlation with glycaemic control (r = 0.178, 0.157, 0.145, p<0.001), while high-density lipoproteins values are negatively correlated (r = -0.019, p<0.001).

    Conclusion: implementing lifestyle changes such as physical activity and dietary modifications are important in the management of BMI, waist circumference and body lipids, which in turn results in improved glycaemic control.

    Research in schizophrenia has advanced tremendously. One hundred and seventy five articles related to Schizophrenia were found from a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. This project aims to examine published research articles, in local and international journals in order to provide a glimpse of the research interest in Malaysia with regards to schizophrenia. Single case study, case series report, reviews and registry reports were not included in this review. Medication trial, unless it concerned a wider scope of psychopharmacology was also excluded from this review. A total of 105 articles were included in this review. Despite numerous genetics studies conducted and published, a definitive conclusion on the aetiology or mechanism underlying schizophrenia remains elusive. The National Mental Health - Schizophrenia Registry (NMHR) proved to be an important platform for many studies and publications. Studies stemmed from NMHR have provided significant insight into the baseline characteristic of patients with schizophrenia, pathway to care, and outcomes of the illness. International and regional collaborations have also encouraged important work involving stigma and discrimination in schizophrenia. Ministry of Health's hospitals (MOH) are the main research sites in the country with regards to schizophrenia research. Numbers of schizophrenia research are still low in relation to the number of universities and hospitals in the country. Some of the weaknesses include duplication of studies, over-emphasising clinical trials and ignoring basic clinical research, and the lack of publications in international and regional journals.

    INTRODUCTION: Spontaneous rupture is a dramatic presentation of HCC and it carries high mortality rate. To study the outcomes of ruptured HCC patients managed at a tertiary referral centre in Malaysia.
    METHODS: A retrospective review of all ruptured HCC patients managed as inpatient at the Department of Hepatobiliary Surgery, Hospital Selayang between January 2001 and December 2010. Data was retrieved from the hospital electronic medical records, Powerchart (Cerner Corporation Inc., USA) and supplemented with registry from Interventional Radiology record of chemoembolization and registry from hepatobiliary operative surgery records.
    RESULTS: There were 22 patients admitted with confirmed diagnosis of ruptured HCC over 10 years period. The common clinical findings on presentation were abdominal pain and presence of shock (36.4%). The mortality rate was 81.8% with only four patients noted to be alive during the follow up. One year overall survival for ER and DR are 40.0% and 72.7% respectively and the median survival in patients treated with DR was 433.3 days whereas it was 212.5 days in ER group.
    CONCLUSIONS: This study supports the clinical practice of TAE should be the first line treatment followed by staged surgery in suitable candidates with ruptured HCC.

    INTRODUCTION: Diabetes care at different healthcare facilities varied from significantly better at one setting to no difference amongst them. We examined type 2 diabetes patient profiles, disease control and complication rates at four public health facilities in Malaysia.
    MATERIALS AND METHODS: This study analyzed data from diabetes registry database, the Adult Diabetes Control and Management (ADCM). The four public health facilities were hospital with specialist (HS), hospital without specialist (HNS), health clinics with family physicians (CS) and health clinic without doctor (CND). Independent risk factors were identified using multivariate regression analyses.
    RESULTS: The means age and duration of diabetes in years were significantly older and longer in HS (ANOVA, p< 0.0001). There were significantly more patients on insulin (31.2%), anti-hypertensives (80.1%), statins (68.1%) and antiplatelets (51.2%) in HS. Patients at HS had significantly lower means BMI, HbA1c, LDL-C and higher mean HDL-C. A significant larger proportion of type 2 diabetes patients at HS had diabetes-related complications (2-5 times). Compared to the HS, the CS was more likely to achieve HbA1c ≤ 6.5% (adjusted OR 1.2) and BP target < 130/80 mmHg (adjusted OR 1.4), the HNS was 3.4 times more likely not achieving LDL-C target < 2.6 mmol/L.
    CONCLUSION: Public hospitals with specialists in Malaysia were treating older male Chinese type 2 diabetes patients with more complications, and prescribed more medications. Patients attending these hospitals achieved better LDL-C target but poorer in attaining BP and lower HbA1c targets as compared to public health clinics with doctors and family physicians.

    The aim of this study is to determine risks factor of mortality among patient with post percutaneous coronary intervention. Estimation of post operative mortality risk factor is essential for planning prevention modalities. This is retrospective cohort study based on secondary data extracted from the National Cardiovascular Disease Database (NCVD-ACS and NCVD PCI). Both these registries were interlinked and was further matched to JPN (Jabatan Pendaftaran Negara/National registration Department) to assess mortality among the patients who underwent PCI and all death which occurred in between 2007, 2008 and 2009. There were 630 patients in this studied. Age, history of diabetes mellitus, peripheral vascular, renal failure and previous percutaneous coronary intervention were univariately associated with mortality. However based on logistics stepwise method, only age and history of renal failure had showed statistically significant and sizeable odds ratio in predicting the patient died of coronary death. Older age and renal failure are the predicting factors for mortality among patients with post percutaneous coronary intervention.

    All around the world, there is growing evidence of the association between psoriasis and comorbidities which increase the risk of cardiovascular disease. This study aims to determine the prevalence of various comorbidities among adult psoriasis patients in Malaysia. A cross-sectional study was conducted among patients in the Malaysian Psoriasis Registry from January 2007 to December 2008. A total of 2,267 adult patients with psoriasis from 13 dermatology centers were included. Prevalence of various comorbidities were: hypertension 25.9%, diabetes mellitus 17.7 %, dyslipidaemia 17.8%, overweight 33.2%, obesity 20.7%, ischaemic heart disease 5.8% and cerebrovascular disease 1.4%. These comorbidities were more prevalent in patients with psoriasis of late-onset and longer duration. Active screening of these comorbidities in all adult psoriasis patients is recommended.

    This study aims to determine the risk factors associated with diabetic retinopathy (DR) among natives and non-natives Sarawakians who were seen at 3 public hospitals and one health clinic in Sarawak. It is a cross sectional study where data on patients with DM were collected by staff at these healthcare facilities and entered into the web-based Diabetic Eye Registry. Univariate and multivariate analysis was used to determine the association factors for DR. DR was significantly less associated with natives (24.4%) compared to non-native Sarawakians (34.1%) (p < 0.001). The odds of getting DR was higher in patients whose duration of DM was more than 20 years (OR = 2.6), who have renal impairment (OR = 1.7) and non-natives (OR = 1.4).

    End stage renal disease (ESRD) patients have a much higher rate of cardiac disease and cardiac mortality as compared with the general population. Revascularisation such as coronary artery bypass grafting (CABG) may also carry a higher rate of complications and morbidity. We compared our ESRD patients who underwent CABG with the general population and ESRD population.

    The National Stroke Registry (NSR) was established in 2009 under National Neurology Registry (NNeuR) . The main objectives of NSR were to describe the demographic and disease pattern of stroke patients in Malaysia, to examine the risk factors and evaluate the specified treatment and outcomes. This prospective observational study was carried out from August 2009 until December 2010 using a standardized case report form which involved two participating hospital, namely Hospital Sultanah Nur Zahirah, Kuala Terengganu and Hospital Seberang Jaya, Pulau Pinang. There were 1018 patients registered. Ischemic stroke accounted for the majority of cases (73.3%). The most common risk factor was hypertension (75.5 %), followed by diabetes mellitus, previous stroke or Transient Ischemic Attack (TIA), hyperlipidemia and active smoker: 45.6%, 25.1%, 22.4%, and 19.4%, respectively. Overall, our stroke management, based on nine stroke key performance indicators (KPI) still needs to be improved. There was a total of 121 mortality cases with the main contributing factor was massive cerebral bleed (21.6%). In conclusion, the findings highlight the important of primary and secondary stroke management. Further and continuous observation with more site date provider (SDP) involvement is needed to get a more comprehensive data on stroke in Malaysia.

    Registration of research proposal to a publicly accessible website with searchable function allows information sharing and ensures research transparency. The National Institutes of Health Malaysia, realising the importance of research registration, established the National Medical Research Register (NMRR) in 2007. The NMRR functions more than just a local register: it also links to ethics approval and MOH medical research grant application. It thus facilitates researchers in their application to the Ministry of Health Research and Ethics Committee (MREC) and for Ministry of Health research grant. In addition, MREC committee members can review research protocol on NMRR website, thus saving much time and resources. From May 2007 till December 2009, more than 3000 people have registered as NMRR public users and more than 1000 research proposals have been uploaded in NMRR. The number of registration of research proposals, clinical trials and industrial sponsored trials steadily increased from year 2007 to year 2009. The web-based NMRR is the first research register in the world that links research proposal registration to ethical review and research grant application. Its future plan is to be linked with publication. Therefore, it is indeed an innovation that Malaysians should be proud of.

    To create a national registry of contact-lens related corneal ulcers (CLRCU) patients in Malaysia with the aim of detecting outbreaks, identifying pattern of causative organisms, determining patient demography, risk factors, wearing patterns and monitoring outcome of treatment. The CLRCU registry is an ongoing patient registry established in 2007 as a surveillance tool used by Malaysian Ministry of Health ophthalmology departments. Notification of patients clinically suspected of CLRCU was performed online through the National Eye Database (NED). Data collected included patient demography, contact lens type, causative organism and treatment outcome. During 2007-2008, a total of 202 patients were notified to the CLRCU registry with a mean age of 26.7 years (71.8% female). All registered patients wore soft contact lens and monthly disposable lenses were the most popular (83.5%). The majority of patients had bacterial CLRCU and the most common causative organism was Pseudomonas (79.7% of bacterial cases). No epidemics were identified during the period of data examination. Use of contact lenses, which is increasing during modern times, may lead to CLRCU as a severe complication. The CLRCU registry is an effective tool which uses a web-based notification system that allows quick and up to date reports of CLRCU cases. This provides the ability to monitor outbreaks of disease and identify important causative and associated factors of the disease which may be used to reduce future incidence.

    Splenectomised thalassaemia patients are at risk of developing sepsis. As the infection may be life-threatening, treatment should be sought and given promptly. A retrospective study was performed amongst our thalassaemia major patients who were splenectomised. The vaccination status of each patient and the types of infections seen were reviewed to obtain a local perspective. In our cohort of 49 splenectomised patients, 25 patients required hospitalization for the treatment of infection. There were a total of 40 febrile episodes within this hospitalised group of which 27.5% were microbiologically documented infection with bacteraemia. The predominant causative organisms were gram negative rods and three patients succumbed to overwhelming septicaemic shock as a result of delayed presentation. Sixty percent of the febrile episodes were clinically documented infection and comprised mainly upper respiratory tract infections. Based on the spectrum of infections seen, there is a need to improve the patients' awareness level so that early treatment is sought. There is also a need to re-address the approach towards vaccination in this immunocompromised group of patients by administering a booster pneumococcal and influenza vaccination in an attempt to reduce morbidity.

    Melioidosis has a high annual incidence and mortality rate in Pahang, Malaysia. We initiated the first melioidosis registry in the country on 1st July 2005 to improve the management of melioidosis in the state. Continuous medical education on melioidosis was carried out in all hospitals in the state to highlight the magnitude of the disease and to educate the doctors on the treatment of the disease. All culture confirmed cases were registered and analysed. During the one-year study period from 1st July 2005 till 30th June 2006, a total of 63 patients had positive culture for Burkholderia pseudomallei. The calculated annual incidence of melioidosis in Pahang state was 4.3 per 100,000 population per year (Adult, 6.0 per 100, 000 population per year and paediatric, 1.6 per 100,000 population per year). There were 55 Malays (87.3%), three Chinese (4.8%), four aborigines (6.3%) and one Indonesian. Nine (14.3%) were less than 18 years old. The median age was 49 years (range: 1-68 years). Only one patient (1.6%) had a previous history of confirmed melioidosis. With this programme, we had observed a decline in adult mortality from 54% to 44%, although this was not statistically significant. However, culture-confirmed relapses had dropped from 19% to nil. Several measures need to be taken to decrease mortality from melioidosis in endemic countries.
