    INTRODUCTION: Specific coffee subtypes and tea may impact risk of pre- and post-menopausal breast cancer differently. We investigated the association between coffee (total, caffeinated, decaffeinated) and tea intake and risk of breast cancer.

    METHODS: A total of 335,060 women participating in the European Prospective Investigation into Nutrition and Cancer (EPIC) Study, completed a dietary questionnaire from 1992 to 2000, and were followed-up until 2010 for incidence of breast cancer. Hazard ratios (HR) of breast cancer by country-specific, as well as cohort-wide categories of beverage intake were estimated.

    RESULTS: During an average follow-up of 11 years, 1064 premenopausal, and 9134 postmenopausal breast cancers were diagnosed. Caffeinated coffee intake was associated with lower risk of postmenopausal breast cancer: adjusted HR=0.90, 95% confidence interval (CI): 0.82 to 0.98, for high versus low consumption; Ptrend=0.029. While there was no significant effect modification by hormone receptor status (P=0.711), linear trend for lower risk of breast cancer with increasing caffeinated coffee intake was clearest for estrogen and progesterone receptor negative (ER-PR-), postmenopausal breast cancer (P=0.008). For every 100 ml increase in caffeinated coffee intake, the risk of ER-PR- breast cancer was lower by 4% (adjusted HR: 0.96, 95% CI: 0.93 to 1.00). Non-consumers of decaffeinated coffee had lower risk of postmenopausal breast cancer (adjusted HR=0.89; 95% CI: 0.80 to 0.99) compared to low consumers, without evidence of dose-response relationship (Ptrend=0.128). Exclusive decaffeinated coffee consumption was not related to postmenopausal breast cancer risk, compared to any decaffeinated-low caffeinated intake (adjusted HR=0.97; 95% CI: 0.82 to 1.14), or to no intake of any coffee (HR: 0.96; 95%: 0.82 to 1.14). Caffeinated and decaffeinated coffee were not associated with premenopausal breast cancer. Tea intake was neither associated with pre- nor post-menopausal breast cancer.

    CONCLUSIONS: Higher caffeinated coffee intake may be associated with lower risk of postmenopausal breast cancer. Decaffeinated coffee intake does not seem to be associated with breast cancer.

    OBJECTIVES: Cardiogenic shock (CS) complicating ST-elevation myocardial infarction (STEMI) carries an extremely high mortality. The clinical pattern of this life threatening complication has never been described in Malaysian setting. This study is to investigate the incidence, clinical characteristics and outcome of STEMI patients with CS in our population.

    DESIGN: A retrospective analysis of STEMI patients from 18 hospitals across Malaysia contributing to the Malaysian National Cardiovascular Database-acute coronary syndrome) registry (NCVD-ACS) year 2006-2013.

    PARTICIPANTS: 16 517 patients diagnosed of STEMI from 18 hospitals in Malaysia from the year 2006 to 2013.

    PRIMARY OUTCOME MEASURES: In-hospital and 30 day post-discharge mortality.

    RESULTS: CS complicates 10.6% of all STEMIs in this study. They had unfavourable premorbid conditions and poor outcomes. The in-hospital mortality rate was 34.1% which translates into a 7.14 times mortality risk increment compared with STEMI without CS. Intravenous thrombolysis remained as the main urgent reperfusion modality. Percutaneous coronary interventions (PCI) in CS conferred a 40% risk reduction over non-invasive therapy but were only done in 33.6% of cases. Age over 65, diabetes mellitus, hypertension, chronic lung and kidney disease conferred higher risk of mortality.

    CONCLUSION: Mortality rates of CS complicating STEMI in Malaysia are high. In-hospital PCI confers a 40% mortality risk reduction but the rate of PCI among our patients with CS complicating STEMI is still low. Efforts are being made to increase access to invasive therapy for these patients.

    OBJECTIVE: Young women form a minority but an important group of patients with acute myocardial infarction (MI) as it can potentially cause devastating physical and socioeconomic impact. This study was aimed to investigate the characteristics and outcomes of young women with MI in Malaysia.

    DESIGN: This is a retrospective analysis of women with ST-elevation MI (STEMI) and non-STEMI (NSTEMI) from 18 hospitals across Malaysia using the Malaysian National Cardiovascular Database registry-acute coronary syndrome (NCVD-ACS).

    PARTICIPANTS: Women patients diagnosed with acute MI from year 2006 to 2013 were identified and divided into young (age ≤ 45, n=292) and older women (age >45, n=5580).

    PRIMARY OUTCOME MEASURE: Comparison of demographics, clinical characteristics and in-hospital management was performed between young and older women. In-hospital and 30-day all-cause mortality were examined.

    RESULTS: Young women (mean age 39±4.68) made up 5% of women with MI and were predominantly of Malay ethnicities (53.8%). They have a higher tendency to present as STEMI compared with older women. Young women have significantly higher rates of family history of premature coronary artery disease (CAD) (20.5% vs 7.8% p<0.0001). The prevalence of risk factors, such as hypertension, diabetes and dyslipidaemia was high in both groups. The primary reperfusion strategy was thrombolysis with no significant differences observed in the choice of intervention for both groups. Other than aspirin, rates of prescriptions for evidence-based medications were similar with >80% prescribed statins and aspirin. The all-cause mortality rates of young women were lower for both in-hospital and 30 days, especially in those with STEMI with adjusted mortality ratio to the older group, was 1:9.84.

    CONCLUSION: Young women with MI were over-represented by Malays and those with a family history of premature CAD. Preventive measures are needed to reduce cardiovascular risks in young women. Although in-hospital management was similar, short-term mortality outcomes favoured young compared with older women.

    INTRODUCTION: PEACE MENA (Program for the Evaluation and Management of Cardiac Events in the Middle East and North Africa) is a prospective registry in Arab countries for in-patients with acute myocardial infarction (AMI) or acute heart failure (AHF). Here, we report the baseline characteristics and outcomes of in-patients with AHF who were enrolled during the first 14 months of the recruitment phase.

    METHODS: A prospective, multi-centre, multi-country study including patients hospitalized with AHF was conducted. Clinical characteristics, echocardiogram, BNP (B-type natriuretic peptide), socioeconomic status, management, 1-month, and 1-year outcomes are reported.

    RESULTS: Between April 2019 and June 2020, a total of 1258 adults with AHF from 16 Arab countries were recruited. Their mean age was 63.3 (±15) years, 56.8% were men, 65% had monthly income ≤US$ 500, and 56% had limited education. Furthermore, 55% had diabetes mellitus, 67% had hypertension; 55% had HFrEF (heart failure with reduced ejection fraction), and 19% had HFpEF (heart failure with preserved ejection fraction). At 1 year, 3.6% had a heart failure-related device (0-22%) and 7.3% used an angiotensin receptor neprilysin inhibitor (0-43%). Mortality was 4.4% per 1 month and 11.77% per 1-year post-discharge. Compared with higher-income patients, lower-income patients had a higher 1-year total heart failure hospitalization rate (45.6 vs 29.9%, p=0.001), and the 1-year mortality difference was not statistically significant (13.2 vs 8.8%, p=0.059).

    CONCLUSION: Most of the patients with AHF in Arab countries had a high burden of cardiac risk factors, low income, and low education status with great heterogeneity in key performance indicators of AHF management among Arab countries.

    PMID: 32807412 DOI: 10.1016/j.jstrokecerebrovasdis.2020.104938
    BACKGROUND AND PURPOSE: The novel severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), now named coronavirus disease 2019 (COVID-19), may change the risk of stroke through an enhanced systemic inflammatory response, hypercoagulable state, and endothelial damage in the cerebrovascular system. Moreover, due to the current pandemic, some countries have prioritized health resources towards COVID-19 management, making it more challenging to appropriately care for other potentially disabling and fatal diseases such as stroke. The aim of this study is to identify and describe changes in stroke epidemiological trends before, during, and after the COVID-19 pandemic.

    METHODS: This is an international, multicenter, hospital-based study on stroke incidence and outcomes during the COVID-19 pandemic. We will describe patterns in stroke management, stroke hospitalization rate, and stroke severity, subtype (ischemic/hemorrhagic), and outcomes (including in-hospital mortality) in 2020 during COVID-19 pandemic, comparing them with the corresponding data from 2018 and 2019, and subsequently 2021. We will also use an interrupted time series (ITS) analysis to assess the change in stroke hospitalization rates before, during, and after COVID-19, in each participating center.

    CONCLUSION: The proposed study will potentially enable us to better understand the changes in stroke care protocols, differential hospitalization rate, and severity of stroke, as it pertains to the COVID-19 pandemic. Ultimately, this will help guide clinical-based policies surrounding COVID-19 and other similar global pandemics to ensure that management of cerebrovascular comorbidity is appropriately prioritized during the global crisis. It will also guide public health guidelines for at-risk populations to reduce risks of complications from such comorbidities.

    PURPOSE: Cataract surgery is the most common intraocular surgery performed all over the world and has advanced technically in recent years. As in all surgeries, complications are unavoidable. Herein we report factors associated with complications and visual outcomes of cataract surgery.

    METHODS: This retrospective cohort study included data of 1,632 cataract surgeries performed from 2007 to 2010 which was obtained from the cataract registry of the Malaysian National Eye Database. Demographic features, ocular and systemic comorbidites, grade of surgeon expertise and duration of surgery, type of anesthesia, intraoperative and postoperative complications, and the type of intraocular lens were recorded. Best corrected visual acuities were compared before and after the operation.

    RESULTS: Mean patient age was 66.9 years with equal gender distribution. The majority of subjects had age related cataracts. Phacoemulsification was done faster than other surgeries, especially by specialist surgeons. History of prior ocular surgery and operations performed under general anesthesia were associated with greater complications. Phacoemulsification was associated with less complications and better visual outcomes. The age and etiology of cataract did not affect complications. Malays, absence of ocular comorbidities, left eyes and eyes operated under local anesthesia were more likely to experience more visual improvement. Gender, age, cause of cataract, systemic comorbidities and surgeon expertise as well as intra-and postoperative complications did not affect the visual outcomes.

    CONCLUSION: Phacoemulsification had good visual outcomes in cataract surgery. Duration of surgery, expertise of the surgeon and complications did not affect the visual outcomes.

    The aims of this retrospective analysis were (i) to examine the trends of quality of life (QoL) scores and (ii) to identify the risk factors for QoL scores among 6908 dialysis patients entering dialysis between 1997 and 2002. The Spitzer QoL Index was the instrument used by the National Renal Registry of Malaysia to assess the QoL amongst dialysis patients. Demographic and biochemical data were analysed to identify risk factors for poor QoL. The median QoL-index score ranged between 9 and 10. Significant risk factors for poor QoL were female gender, age > 40, diabetes, cohort starting dialysis 2001-2002, haemodialysis modality, body mass index < 18.5, albumin < 30g/dL, cholesterol < 3.2 mmol/L, haemoglobin < 10 g/dL, diastolic blood pressure of > 90 mHg, iPTH < 100 pg/ml. The overall QoL of dialysis patients is satisfactory. The negative impact of diabetes and haemodialysis on QoL warrants further evaluation as each factor involves 50% and 90% of our dialysis population.

    An audit of Diabetes Control and Management-Diabetes Registry Malaysia (ADCM-DRM) was started to monitor the provision of diabetes care in the country. A total of 20,646 patients were registered in the registry until 31st December 2008. This report set out to determine the Type 2 diabetes controls and treatment profiles of these cohorts of patients. This was a registry-based observational study conducted from May to December, 2008. An online standard case record form was available for site data providers to register their diabetic patients aged 18 years old and above annually. Demographic data, diabetes duration, treatment modalities, as well as various risk factors and diabetes complications were reported. Data were analyzed using Data Analysis and Statistical Software (Stata) version 9. A total of 81 centres, 6 of which were hospitals, participated in this registry until 31st December 2008, contributing a total of 20646 patients. A majority of them (99.2%) had Type 2 diabetes mellitus. The mean HbA1c was 8.0% (SD 2.10), with 30.1% and 17.9% of the patients who attained HbA1c < 7% and HbA1c < 6.5%, respectively. Metformin was prescribed more than sulfonylurea while only 11% had insulin. A review of the diabetic care policy and strategies in the primary health care clinics is needed to implement a more effective treatment of diabetes in this country.

    Suicidal feelings and a sense of hopelessness have been regarded as part of the ageing process more so in the context of being elderly and having physical difficulties. As older adults are the fastest growing population in the world, suicides among this population is also expected to increase. The authors retrospectively reviewed all cases recorded by the National Suicide Registry Malaysia (NSRM) for the year 2009. Suicide in victims 65 years and older totaled 23 in number and accounted for 7.1% of all suicides. All the cases were autopsied. The case records were retrospectively analyzed with respect to age, gender, ethnicity and method of death. Comparisons were also made between males and females, levels of education, presence of stressor and life events antecedent to suicide. The ages of these suicide victims ranged from 65 to 94 years. Men comprised almost 70% of the cases. The average age of the victim was 73 years. Hanging was the most common method of suicide, accounting for 56.5% of the cases. Other methods included jumping from height (13.1%), exposure to unspecified chemicals (13.1% ), jumping/lying before moving object (4.3%), exposure to pesticides (4.3%) and injuring oneself using sharp object (4.3%). Death of a loved one, legal problems, financial problems and physical illness were the stressors identified contributing to the suicide act.

    OBJECTIVES: There is limited data on congenital heart disease (CHD) from the lower- and middle-income country. We aim to study the epidemiology of CHD with the specific objective to estimate the birth prevalence, severity, and its trend over time.

    DESIGN: A population-based study with data retrieved from the Pediatric Cardiology Clinical Information System, a clinical registry of acquired and congenital heart disease for children.

    SETTING: State of Johor, Malaysia.

    PATIENTS: All children (0-12 years of age) born in the state of Johor between January 2006 and December 2015.

    INTERVENTION: None.

    OUTCOME MEASURE: The birth prevalence, severity, and temporal trend over time.

    RESULTS: There were 531,904 live births during the study period with 3557 new cases of CHD detected. Therefore, the birth prevalence of CHD was 6.7 per 1000 live births (LB) (95% confidence interval [CI]: 6.5-6.9). Of these, 38% were severe, 15% moderate, and 47% mild lesions. Hence, the birth prevalence of mild, moderate, and severe CHD was 3.2 (95% CI: 3.0-3.3), 0.9 (95% CI: 0.9- 1.1), and 2.6 (95% CI: 2.4-2.7) per 1000 LB, respectively. There was a significant increase in the birth prevalence of CHD, from 5.1/1000 LB in 2006 to 7.8/1000 LB in 2015 (P

    BACKGROUND: Octogenarians and beyond have often been neglected in the populational study of disease despite being at the highest point of non-modifiable disease risk burden and the fastest-growing age group for the past decade. This study examined the characteristics and in-hospital management of octogenarian patients with acute coronary syndrome (ACS) in a multi-ethnic, middle-income country in South East Asia.

    METHOD: This retrospective study utilised the Malaysian National Cardiovascular Disease- ACS (NCVD-ACS) registry. Consecutive patient data of those ≥80 years old admitted with ACS at 24 participating hospitals from 2008 to 2017 (n = 3162) were identified. Demographics, in-hospital intervention, and evidence-based pharmacotherapies over the 10-years were examined and compared across groups of interests using the Chi-square test. Multivariate logistic regression was used to calculate the adjusted odds ratio of receiving individual therapies according to patients' characteristics.

    RESULTS: Octogenarians made up 3.8% of patients with ACS in the NCVD-ACS registry (mean age = 84, SD ± 3.6) from 2008 until 2017. The largest ethnic group was Chinese (44%). Most octogenarians (95%) have multiple cardiovascular risk factors, with hypertension (82%) being the main. Non-ST-elevation myocardial infarction (NSTEMI) predominated (38%, p

    Background: Death resulting from the acquired immunodeficiency syndrome (AIDS) is a worldwide concern. This study is aimed at determining the overall median survival time, and the prognostic factors of mortality among AIDS-infected patients in North-East Peninsular Malaysia.

    Methods: In 2018, a retrospective cohort study stretching from January to April was conducted. This study involved a review of data obtained from the National AIDS Registry. A total of 1,073 AIDS cases diagnosed from 1 January 2010 to 31 December 2014 were selected, and follow-up procedures were conducted until 31 March 2015 (a 3-month follow-up). The Kaplan-Meier plot and Cox's proportional hazard regression were used for data analyses.

    Results: 564 (52.5%) patients died due to AIDS, while the remaining 509 (47.4%) were censored. The overall median survival time was 11 months. The probability of survival in 1-year, 2-year, 3-year, 4-year and 5-year periods were 49.1%, 47.8%, 47.3%, 47.0% and 46.7%, respectively. Multiple Cox regression revealed that the significant prognostic factors were age 30-49 years [adjusted hazard ratio (Adj. HR) 1.57; 95% CI: 1.14, 2.16; P = 0.006], male (Adj. HR 1.39; 95% CI: 1.07, 1.79; P = 0.012), unemployed (Adj. HR 1.40; 95% CI: 1.12, 1.75; P = 0.003) and HIV-TB co-infection (Adj. HR 1.78; 95% CI: 1.37, 2.31; P < 0.001).

    Conclusion: The overall median survival time among AIDS patients in North-East Peninsular Malaysia was revealed to be short, in comparison to the other studies. The chances for survival can be improved with more emphasis on early detection (to ensure early treatment) and social support, particularly for HIV-TB co-infected patients, as well as for younger and unemployed patients.

    Introduction: Children and adolescents requiring mental health services are increasing. This paper is a registry of new clients in the Child and Adolescent Mental Health (CAMH) outpatient clinic of Hospital Sultan Abdul Halim (HSAH), Sungai Petani, Kedah, Malaysia from January 2014 to December 2014.
    Objectives: We aimed to determine the trends of different types of mental disorders in first contact clients at an outpatient CAMH clinic in HSAH. Thereafter, we sought to compare the differences in demographics with types of illness and treatments modalities. Method: We reviewed electronic case records retrospectively for the study period from January 2014 to December 2014 and universal sampling was done.
    Results: During the study period, there were 160 new cases. The highest number of patients were from the primary school age group with a mean age of 9.98 years. The highest incidence was Attention Deficit Hyperactivity Disorder (23.8%), followed by Autism Spectrum Disorder (17.5%) and others at 15.6%. Out of those sampled, 61% were treated pharmacologically and 39% were receiving non-pharmacological treatment.
    Conclusions: There is a need to enhance and expand services to enable the client and family to obtain the necessary intervention. With improved screening and empowerment of the family, better outcomes could be achieved for the client.

    OBJECTIVE:: Objectives. To determine the prevalence and risk factors for diabetic foot infection (DFI), and to identify factors associated with delayed wound healing of diabetic foot ulcer (DFU).

    METHOD:: The retrospective study was performed in a referral wound care clinic in Hospital Kuala Lumpur. Data was collected from January 2014 to October 2016 on DFU patients who attended this clinic.

    RESULTS:: Of the 340 patients (216 male and 124 female) DFU patients who attended the clinic (mean age: 58.1±10.8 years old), 41.5% presented with infection with a mean cross-sectional ulcer area of 21.5±33.2cm2. Binary logistic regression analysis revealed that patients of Chinese ethnicity (OR: 3.39; 95%CI 1.49 to 7.70), with fasting blood glucose ≥7mmol/l (OR: 3.41; 95%CI 1.57 to 7.39), ulcer size ≥10cm2 (OR: 2.90; 95%CI 1.45 to 5.82) and blood pressure ≥140/90mmHg (OR: 2.52; 95%CI 1.54 to 4.14) were more likely to develop DFI. The median healing time for patients with DFUs was three months. There were six variables identified as significantly associated with prolonged healing time of DFU, namely presence of infection (p<0.001), poor glycaemic control with fasting blood glucose ≥7mmol/l (p<0.001), high blood pressure ≥140/90mmHg (p<0.001), large DFU size ≥2cm2 (p<0.001), history of amputation (p<0.005) and plantar location of the DFU (p<0.05).

    CONCLUSION:: Large DFU size, poor glycaemic and blood pressure control are common risk factors for both DFU and DFI. Unexpected high prevalence and ethnicity risk factor for DFI urge more comprehensive primary and secondary preventative strategies to reduce its incidence.

    Cancer incidences as well as the most prevalent cancer types vary greatly across Asian countries since people have differing health behaviors as well as lifestyle factors related to cancer risk. Countries have varying systems of government organization, laws, resources, facilities, and management strategies for addressing the cancer burden. Examples such as Korea and Japan with existing national cancer control programs need to focus on early screening and detection and quality of screening methods. If screening and detection increase to cover more than 50% of the target population, survival rate increases and thus the number of cancer patients detected increases resulting in higher medical cost. Thus, expansion of cancer screening, in addition to smoking prevention, immunization increase, and diet control awareness, are needed for cancer prevention strategies. Countries such as Thailand, China, Malaysia, and Turkey need to begin organized efforts to reduce cancer deaths through state-wide cancer screening programs. Strategies focused on increasing survival among cancer patients are also needed. In addition, government organizations and law regulations need to be in place as the first step towards cancer prevention. For the countries such as Nepal, Pakistan, Mongolia, and Iraq which do not have any cancer-related organizations in place, the first step that is needed is to raise public awareness about cancer; a public awareness campaign is the number one priority and should begin immediately. The easiest and most feasible step at this point is dissemination of cancer education materials during school health education and physical health screening. This must be started immediately because we need to avoid the development of existing cancers where patients will need to seek specialized cancer treatment facilities that are non-existent in these regions. In addition, hospitals need to take a step further and start undergoing registration of cancer prevalence and incidence cases beginning at the regional level. Through the hospital census, countries will be able to determine the magnitude of the cancer burden. Moreover, countries with professionals and researchers with advanced cancer research, education, and training also need to contribute through international cooperation.

    Many recent studies investigated the prognostic value of new biomarkers in breast cancer using data from cancer registries. Some of these studies were conducted using only patients for whom biomarker status was available (or tested). Using human epidermal growth factor receptor 2 (HER2) as an example, we determined whether testing for a recently introduced biomarker was associated with the outcome of women with breast cancer.

    OBJECTIVE: To study the impact of various clinicopathological factors on short-term survival in a cohort of breast cancer patients treated at the University of Malaya Medical Centre (UMMC).
    METHODS: All cases of breast cancer treated at UMMC from January 1999 to June 2001, except for stage IV disease, were included in the study. Survival analysis was carried out using Kaplan-Meier for univariate analysis and Cox regression for multivariate analysis. The log-rank test was used to test the significance of differences between the different survival curves.
    RESULTS: A total of 385 patients were included. The mean patient age at presentation was 50.3 years (SD, 11.4); 198 (51.4%) patients had lymph node-positive disease, and 187 (48.6%) had node-negative disease. The mean follow-up period was 18.7 months (SD, 8.8). The Malay ethnic group, tumours of larger size, node-positive disease, more than five positive lymph nodes, oestrogen receptor (ER) negativity and the presence of lymphovascular invasion were significant prognostic factors for shorter recurrence-free survival (RFS) in the univariate analysis. In the multivariate analysis, ER negativity was the only independent adverse prognostic factor for RFS. For overall survival (OS), tumours of larger size, node-positive disease, more than five positive lymph nodes, ER negativity and high grade tumours were associated with significantly shorter OS. However, more than five positive lymph nodes was the only independent prognostic factor for shorter OS in the multivariate analysis. Further multivariate analysis of the patients with node-positive disease showed that the Malay ethnic group, ER negativity and more than five positive lymph nodes were independent prognostic factors for shorter RFS. On the other hand, ER negativity and more than five positive lymph nodes were independent negative prognostic factors for OS in this subgroup of patients.
    CONCLUSION: The evaluation of various prognostic factors would provide useful information on disease progression in local patients, especially for the planning of adjuvant therapies and follow-up protocols. Differences in the pattern of breast cancer among the different ethnic groups in Malaysia warrant further studies.

    Percutaneous biopsy in breast cancer has been associated with an increased risk of malignant cell seeding. However, the importance of these observations remains obscure due to lack of corroborating evidence from clinical studies. We determined whether method of biopsy is associated with breast cancer survival. This hospital registry-based cohort study included 3416 non-metastatic breast cancer patients diagnosed from 1993 to 2011 in a tertiary setting. Factors associated with biopsy methods were assessed. Multivariable Cox regression analysis was used to determine the independent prognostic impact of method of biopsy. Overall, 990 patients were diagnosed by core needle biopsy (CNB), 1364 by fine needle aspiration cytology (FNAC), and 1062 by excision biopsy. Excision biopsy was significantly associated with more favorable tumor characteristics. Radiotherapy modified the prognostic impact of biopsy method (Pinteraction
