Objective: To develop a simple, sensitive, precise, and accurate stability-indicating high performance thin-layer chromatographic method for analysis of curcumin (the main active constituent of turmeric). Methods: The separation was achieved on TLC aluminum plates precoated with silica gel 60F254 using toluene-chloroform-methanol (5:4:1, v/v/v) as a mobile phase. Densitometric analysis was performed at 430 nm. Results: This system was found to have compact spot of curcumin at RF value of (0.31±0.02). For the proposed procedure, linearity (r2= 0.99354 ± 0.00120), limit of detection (50 ng/spot), limit of quantification (200 ng/spot), recovery (ranging from 98.35% - 100.68%), and precision (≤2.25%) were found to be satisfactory. Statistical analysis reveals that the content of curcumin in different geographical region varied significantly.Conclusions:The highest and lowest concentration of curcumin in Turmeric was found to be present in sample of Erode (Tamilnadu) and Surat (Gujrat) respectively which inferred that the variety of turmeric found in Erode (Tamilnadu) is much superior to other region of India.

Patients with Benign Prostatic Hyperplasia (BPH) commonly presents with lower urinary tract symptoms (LUTS), which can be of obstructive symptoms such as hesitancy, incomplete voiding, post void dribbling or of irritative symptoms such as urgency, frequency and nocturia. Various recent studies indicate that nocturia is a very important and bothersome lower urinary tract symptom especially among patients with Benign Prostatic Hyperplasia (BPH). The aim of the study was to determine the frequency of common urinary symptoms among patients with BPH in HUSM as well as to evaluate the extent of bothersomeness of each and every symptom to these patients. This study too was aimed at evaluating the success of TURP in resolving pre operative LUTS. This was a questionnaire-based survey using a validated ICSBPH model whereby patients with BPH were selected and quizzed personally by an investigator. A subset of patients who had undergone TURP was further questioned regarding their satisfaction with the procedure. When nocturia is defined as waking up at night once or more to pass urine, the prevalence of nocturia was about 90%, but only 1 in 6 patients considered this is a very serious symptom. Even if the definition was changed to waking up twice or more, the prevalence is still quite high at over 80%. Urgency was noted in half of the patients, but only a quarter of them consider it a serious problem. 1 in 5 patients experienced significant leak and almost all consider it serious. About one third of the studied population had to be catheterized due to urinary obstruction and interestingly only about half of them considered it as a very serious event. Overall, a great majority of these patients considered suffering from these urinary symptoms for the rest of their life as very devastating. This study concludes that although the prevalence of nocturia was high among BPH patients, but it was not considered serious by majority of them. In fact, LUTS in our BPH patients did not differ much from BPH patients elsewhere. On the whole, TURP resolved most of the LUTS effectively.

Introduction: Morinda citrifolia or also known as noni is commonly consumed raw or blanched as side dishes or ‘ulam’. As cancer is one of the most leading causes of death in the world, we aimed to evaluate the anti-proliferative potential of noni shoot against various types of cancer cell lines. Methods: The breast cancer (MDA-MB-231), liver cancer (HepG2), and colorectal cancer (HT-29) cell lines were treated with 70% ethanol extract of noni shoot for cytotoxicity testing using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptosis induction effects were examined using AO/PI dual fluorescent assay and cell cycle analysis using flow cytometry. Gas chromatography-mass spectrometry (GCMS) was also carried out to characterize the active compounds in noni shoot. Results: The cytotoxicity assay demonstrated noni shoot had IC50 of 49.72 µg/mL, 307.5 µg/mL and 65.43 µg/ mL against MDA-MB-231, HepG2, and HT-29 cell lines, respectively. The AO/PI staining showed apoptotic bodies such as cell blebbing, chromatin condensation, and nuclear fragmentation was markedly induced in the selected cancer cell lines-treated with noni shoot extract. Apoptosis induction by noni shoot was showed by a significant increase in sub G0/G1 phase in MDA-MB-231 and HT-29 cell lines of cell cycle analysis. It was found that noni shoot extract contained mostly acetic acid and ethriol that may contribute to its anti-cancer properties. Conclusion: These findings showed the potential anticancer properties of noni shoot extract thereby, further studies are needed to understand the mechanism of noni as anti-cancer agent and possibility to be developed as a nutraceutical or functional food products.

Varicella zoster infection is one of the self-limiting viral infections during childhood and dengue fever is an endemic infection in Malaysia, which commonly occurs in the form of nonspecific febrile illness at the initial stage. It is rare for the two viral infections to occur simultaneously. A case of dengue fever without warning sign in a five-year old girl was reported, with early symptoms of fever and vesicular rashes. She was clinically diagnosed with varicella zoster infection during the first visit. Surprisingly, she remained febrile even on day six of illness despite no new vesicular lesions on her skin. Due to suspicion of another infection, follow-up investigation was done and revealed isolated thrombocytopenia. This finding was confirmed with positive NS1Ag. A case of rare dengue fever concomitant with varicella zoster infection was reported.

Cytotoxicity is a predominant biological evaluation applied to search for a suitable and non-toxic bioactive compound and to determine the biocompatibility of medical devices-related human body. The broad usage of cytotoxicity tests leads to a robust establishment of cytotoxicity assays with high sensitivity and prompt results. In vitro assays are always prioritized over in vivo due to the reproducible data, reduce numbers of animal used and easily accessible material. Compounds concentration that execute 50% of cell population is determined by calculating the IC50. According to ISO10993, cytotoxicity tests must be performed to determine the biocompatibility of medical devices that has contact with human body. This is crucial to ensure the safety of research and its clinical use. Under the recommendation of ISO10995-Part 5, three categories of tests have been documented; extract elution, direct contact and indirect contact test. Each category plays significant role depending on the nature of experiment and sample used.

Introduction: Intensive care unit (ICU) patients are at the greatest risk of acquiring nosocomial infections, partly because of their serious underlying disease, but also by exposure to life-saving invasive procedures. Hospital-acquired infections increase patient morbidity, increase the length of hospital stay and hospital costs, and also increases mortality rate. The basic knowledge of organisms infecting ICU patients is very important to empirically select appropriate antibiotics, so that the most likely infecting organisms are addressed. Objective: The aim of the study was to find out the etiologic agents causing infection in medical intensive care unit patients. Results In our study of 289 patients, 180 (62.3%) showed a growth of organism during the stay in ICU. The most common site of infection was the respiratory tract in 138 patients (47.8%) with 60 patients (20.8%) showing Acinetobacter baumannii.

Introduction: This study aimed to determine the views and practices of healthcare providers and barriers they encountered when implementing the national health screening program for men in a public primary care setting in Malaysia. Methods: An online survey was conducted among healthcare providers across public health clinics in Malaysia. All family medicine specialists, medical officers, nurses and assistant medical officers involved in the screening program for adult men were invited to answer a 51-item questionnaire via email or WhatsApp. The questionnaire comprised five sections: participants’ socio-demographic information, current screening practices, barriers and facilitators to using the screening tool, and views on the content and format of the screening tool. Results: A total of 231 healthcare providers from 129 health clinics participated in this survey. Among them, 37.44% perceived the implementation of the screening program as a “top-down decision.” Although 37.44% found the screening tool for adult men “useful,” some felt that it was “time consuming” to fill out (38.2%) and “lengthy” (28.3%). In addition, ‘adult men refuse to answer’ (24.1%) was cited as the most common patient-related barrier. Conclusions: This study provided useful insights into the challenges encountered by the public healthcare providers when implementing a national screening program for men. The screening tool for adult men should be revised to make it more user-friendly. Further studies should explore the reasons why men were reluctant to participate in health screenings, thus enhancing the implementation of screening programs in primary care.

Introduction: Anacardium occidentale or cashew are popular traditional food and have raised research interest for complementary cancer treatment. Cancer has become leading cause of death and treatment involved severe side effects. In present study, we aim to study the anti-proliferative effects of cashew shoots in breast cancer (MDAMB-231), colorectal cancer (HT-29) and liver cancer (HepG2) cell lines. Methods: Cell lines were treated with 70% ethanolic cashew extract for cytotoxicity test with MTT assay. AO/PI dual fluorescent assay and RNase/PI staining were used to determine apoptosis induction effects. Phytochemicals screening was carried out by using gas chromatography mass spectrometry (GCMS) and liquid chromatography mass spectrometry (LCMS). Results: The cytotoxicity assay of cashew shoot extract demonstrated IC50 of 81.1 ± 0.11 μg/ml for MDA-MB-231, 307.5 ± 2.31 μg/ml for HT-29 and 272.6 ± 1.91 μg/ml for HepG2 cell lines. The apoptotic bodies include chromatin condensation, cell blebbing and nuclear fragmentation and apoptosis induction were shown by AO/PI staining. There was significant increase of cell count in sub-G0 phase in MDA-MB-231 cell lines treated with cashew shoot extract. It was demonstrated that cashew shoot extract contained 38 compounds from GCMS such as sitosterol, tannin, pyrogallol, phenol and 20 compounds from LCMS such as citric acid, gallic acid, myricetin and hinokiflavone that may give rise to its anti-cancer effect. Conclusion: Cashew shoot extract demonstrated potential anti-cancer properties thus further study is required to investigate its mechanism as anti-cancer agent.
