In this study, the effects of temperature on drying kinetics and eurycomanone content of
Eurycoma longifolia roots were investigated to determine the optimum temperature for
drying of this herb. The roots were subjected to drying temperatures of 40, 50, 60 and 70°
C. The drying kinetics data indicated that the drying rate increased with increase in
temperature but decreased with time. The drying process took place in the falling rate
period. Three established thin layer drying models include Page, Midili and Logarithmic
were employed to describe the drying process. The Midili model was found as the best
fitting model in representing the process. The quality of the products was evaluated by
comparing the content of its active compound, eurycomanone, quantified using an ultra
performance liquid chromatography (UPLC). The fastest drying process was achieved at
70°C, but UPLC results showed that the product suffered at 18% reduction in
eurycomanone content as compared to the control. Based on the findings of this work, the
optimum drying temperature for E. longifolia roots is 60°C.

Mohamed Saini S, Muhamad Radzi A, Abdul Rahman AH

Asia Pac Psychiatry, 2012 Jun;4(2):126-30.
PMID: 26767356 DOI: 10.1111/j.1758-5872.2012.00190.x

The serotonin transporter promoter (5-HTTLPR) is a potential susceptibility locus in the pathogenesis of major depressive disorder. However, data from Malaysia is lacking. The present study aimed to determine the association between the homozygous short variant of the serotonin transporter promoter gene (5-HTTLPR) with major depressive disorder.

INTRODUCTION: Colorectal cancer (CRC) is the second most common cancer in Malaysia with 65% detected at stage III and IV. Despite the increasing incidence of cancers including CRC, Malaysia has yet to implement populationbased screening for cancers. The objective of this paper is to review the strategic planning and implementation of the CRC screening program in Malaysia.
METHODS: A desk review was conducted from August to October in 2018, to examine, review and describe the historical perspective, strategic planning and implementation of the current CRC screening program in Malaysia.
RESULTS: The main policy documents related to CRC screening are the National Strategic Plan for Cancer Control Programme 2016-2020, the Clinical Practice Guideline for Management of Colorectal Carcinoma 2017, and the Implementation Guideline for CRC Screening in Malaysia 2014. Several papers have been published on the epidemiology of CRC in Malaysia. Between 2014 and 2018, 127,957 men and women were screened using immunochemical Faecal Occult Blood Test (iFOBT); 9.3% had positive iFOBT results and were referred for colonoscopy. For those who underwent colonoscopy, CRC detection rate was 4.1% and 13.9% for pre-malignant conditions. Barriers were identified along the continuum of screening process, including patient, provider, and system factors.
CONCLUSION: Although population-level organised screening programmes are preferable to opportunistic screening, the CRC programme in Malaysia was tailored to meet the needs of the population based on available existing resources. A well-mapped budget for the entire screening programme continuum, a strong partnership between stakeholders and an opportunistic screening strategy is crucial to address the rising incidence of CRC.

We report a case of a 33-year-old woman who underwent stress and rest myocardial perfusion scintigraphy (MPS) to exclude coronary artery disease. MPS images showed an apparent dextrocardia with a right-sided septal wall uptake. The electrocardiograph showed a right axis deviation with dominant R waves at leads aVR and V1. Upon retrieval of the patient's medical records, she had an underlying transposition of great arteries and underwent a Senning atrial switch surgery. Hence, the MPS images demonstrated a prominent right ventricular wall due to its function as the "systemic" ventricle with minimal uptake in the "pulmonary" left ventricle.

Age has been suggested to modify systemic lupus erythematosus expression. In this study we have attempted to study 13 patients with late onset (40 years and above) and 90 with early onset disease (below 40 years) to determine whether age-related differences in disease expression exist and whether the genetic make-up influences the age of disease onset. We found that patients with late onset disease initially presented with pericarditis (31% vs 3%, P<0.005) and a lower incidence of malar rash (31% vs 57%, p<0.05). During the disease course, there was a lower incidence of mucocutaneous symptoms especially malar rash (p<0.005) and psychosis (p<0.05) in the late onset group. Serological parameters were similar in both groups. There was a prevalence of HLA-DQA1*0103 in Chinese patients with late onset disease (pcorr=0.004). These findings suggest that a subgroup of late onset patients may experience milder disease and that the risk conferred by the HLA-DQA1*0103 may be significant among these patients.

Transforming growth factor beta-1 (TGF-beta-1) is a multifunctional cytokine involved in the regulation of growth and differentiation of both normal and transformed cells. The main aim of this study was to determine whether TGF-beta-1 or alpha fetoprotein (AFP) or the combination of the two is a better indicator for hepatocellularcarcinoma (HCC). Serum TGF-beta-1 and AFP were measured by ELISA in 40 healthy subjects, 23 patients with hepatocellular carcinoma (HCC), 70 patients with hepatitis B, 26 patients with hepatitis C and 16 patients with liver cirrhosis (LC). Patients with liver diseases showed significantly higher serum TGF-beta-1 values (> 3 fold) compared to control subjects. As for serum AFP, significant elevation was only observed for HCC cases. Serum TGF-beta-1 exhibited higher percent sensitivity compared to serum AFP in all liver diseases. Combination of serum TGF-beta-1 and AFP increased specificities in all cases studied. In conclusion, serum TGF-beta-1 is a more sensitive marker for HCC when compared to serum AFP and its specificity is increased when combined with serum AFP.

Mohamed Saini S, Nik Jaafar NR, Sidi H, Midin M, Mohd Radzi A, Abdul Rahman AH

Compr Psychiatry, 2014 Jan;55 Suppl 1:S76-81.
PMID: 23410635 DOI: 10.1016/j.comppsych.2012.12.005

The risk variants have been shown to vary substantially across populations and a genetic study in a heterogeneous population might shed a new light in the disease mechanism. This preliminary study aims to determine the frequency of the serotonin transporter gene polymorphism (5-HTTLPR) in the three main ethnic groups in Malaysia and its association with bipolar disorder.
Fulltext The effects of angiotensin-converting enzyme gene polymorphism on the progression of immunoglobulin A nephropathy in Malaysian patients

Draman CR, Kong NC, Gafor AH, Rahman AF, Zainuddin S, Mustaffa WM, et al.

PMID: 19037561

Angiotensin-converting enzyme (ACE) gene polymorphism, especially the deletion/deletion (DD) genotype, is associated with the disease progression of immunoglobulin A (IgA) nephropathy patients in various studies from both Asia Pacific and European populations. However, recent studies within the same populations were unable to reproduce the same results. Hence, we had studied the distribution of the DD genotype, the association between ACE gene polymorphism and the disease progression, and the factors (other than ACE gene polymorphism) which were involved in the disease progression of our local patients.
Oncologist-led BRCA counselling improves access to cancer genetic testing in middle-income Asian country, with no significant impact on psychosocial outcomes

BACKGROUND: Identifying patients with BRCA mutations is clinically important to inform on the potential response to treatment and for risk management of patients and their relatives. However, traditional referral routes may not meet clinical needs, and therefore, mainstreaming cancer genetics has been shown to be effective in some high-income and high health-literacy settings. To date, no study has reported on the feasibility of mainstreaming in low-income and middle-income settings, where the service considerations and health literacy could detrimentally affect the feasibility of mainstreaming.
METHODS: The Mainstreaming Genetic Counselling for Ovarian Cancer Patients (MaGiC) study is a prospective, two-arm observational study comparing oncologist-led and genetics-led counselling. This study included 790 multiethnic patients with ovarian cancer from 23 sites in Malaysia. We compared the impact of different method of delivery of genetic counselling on the uptake of genetic testing and assessed the feasibility, knowledge and satisfaction of patients with ovarian cancer.
RESULTS: Oncologists were satisfied with the mainstreaming experience, with 95% indicating a desire to incorporate testing into their clinical practice. The uptake of genetic testing was similar in the mainstreaming and genetics arm (80% and 79%, respectively). Patient satisfaction was high, whereas decision conflict and psychological impact were low in both arms of the study. Notably, decisional conflict, although lower than threshold, was higher for the mainstreaming group compared with the genetics arm. Overall, 13.5% of patients had a pathogenic variant in BRCA1 or BRCA2, and there was no difference between psychosocial measures for carriers in both arms.
CONCLUSION: The MaGiC study demonstrates that mainstreaming cancer genetics is feasible in low-resource and middle-resource Asian setting and increased coverage for genetic testing.
