Objectives: The aim of this study was to analyze the TTI and outcomes of ART among MMT clients in primary health-care centers in Kuantan, Pahang.
Materials and Methods: This was a retrospective evaluation of MMT clients from 2006 to 2019. The TTI was calculated from the day of MMT enrolment to ART initiation. The trends of CD4 counts and viral loads were descriptively evaluated. Cox proportional hazard model was used to analyze the survival and treatment retention rate.
Results: A total of 67 MMT clients from six primary health-care centers were HIV-positive, of which 37 clients were started on ART. The mean TTI of ART was 27 months. The clients who were given ART had a mean CD4 count of 119 cells/mm3 at baseline and increased to 219 cells/mm3 after 6 months of ART. Only two patients (5.4%) in the ART subgroup had an unsuppressed viral load. The initiation of ART had reduced the risk of death by 72.8% (hazard ratio = 0.27, P = 0.024), and they are 13.1 times more likely to remain in treatment (P < 0.01).
Conclusion: The TTI of ART was delayed in this population. MMT clients who were given ART have better CD4 and viral load outcomes, helped reduced death risk and showed higher retention rates in MMT program.
Objectives: A cross-sectional survey was carried out and sent to a total of 868 specialists working primarily in the ICU. The aim of this study was to explore knowledge, perception, and the antibiotic prescribing practice among specialists and advanced trainees in Malaysian ICU.
Materials and Methods: A cross-sectional survey was used, consisted of three sections: knowledge, perception, and antibiotic prescribing practice in ICU. Three case vignettes on hospital-acquired pneumonia (HAP), infected necrotizing pancreatitis (INP), and catheter-related bloodstream infection (CRBSI) were used to explore antibiotic prescribing practice.
Results: A total of 868 eligible subjects were approached with 104 responded to the survey. Three hundred eighty-nine antibiotics were chosen from seven different classes in the case vignettes. All respondents acknowledged the importance of pharmacokinetic/pharmacodynamic (PK/PD) in antibiotic optimization and majority (97.2%) perceived that current dosing is inadequate to achieve optimal PK/PD target in ICU patients. Majority (85.6%) believed that antibiotic dose should be streamlined to the organisms' minimum inhibitory concentration (MIC). In terms of knowledge, only 64.4% provided the correct correlations between antibiotics and their respective PK/PD targets. Compliance rates in terms of antibiotic choices were at 79.8%, 77.8%, and 27.9% for HAI, INP, and CRBSI, respectively.
Conclusion: Malaysian physicians are receptive to use PK/PD approach to optimize antibiotic dosing in ICU patients. Nonetheless, there are still gaps in the knowledge of antibiotic PK/PD as well as its application in the critically ill, especially for β-lactams.
METHODS: This study was designed to investigate the effect of SynacinnTM and its individual biomarkers on drug metabolizing enzymes (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4 (Midazolam), CYP3A4 (Testosteron)), to assess its herb-drug interaction potential through cytochrome P450 inhibition assay. This study was conducted using liquid chromatography- tandem mass spectroscopy (LC-MS/MS) using probe substrates using human liver microsomes against CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4 (Midazolam) and CYP3A4 (Testosteron).
RESULTS: Result showed that SynacinnTM at maximum concentration (5000 µg/ml) 100% inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4 (Midazolam) and CYP3A4 (Testosteron). IC50 values determined were 0.23, 0.60, 0.47, 0.78, 1.23, 0.99, 1.01, and 0.91 mg/ml for CYP 1A2, 2B6, 2C8, 2C9, 2C19, 2D6, 3A4 (midazolam) and 3A4 (testosterone), respectively. Meanwhile, all individual biomarkers showed no, less or moderate inhibitory effect towards all the tested CYP450 except for curcumin that showed inhibition of CYP2C8 (91%), CYP2C9 (81%) and CYP2C19 (72%) at 10µM.
CONCLUSION: Curcumin was found to be an active constituent that might contribute to the inhibition of SynacinnTM against CYP2C8, CYP2C9 and CYP2C19. It can be suggested that SynacinnTM can be consumed separately from a drug known to be metabolized by all tested CYP450 enzymes.
MATERIAL/METHODS: Fifty female mice, aged 4-6 weeks, were used in this study. Animals were superovulated, cohabitated overnight, and sacrificed. Fallopian tubes were excised and flushed. Embryos at the 2-cell stage were collected and cultured to obtain 4- and 8-cell stages before being cryopreserved using vitrification and slow freezing. Fixed embryos were stained with fluorescence-labelled antibodies against actin and tubulin, as well as DAPI for staining the nucleus. Labelled embryos were scanned using CLSM and images were analyzed with Q-Win software V3.
RESULTS: The fluorescence intensity of both vitrified and slow-frozen embryos was significantly lower for tubulin, actin, and nucleus as compared to non-cryopreserved embryos (p<0.001). Intensities of tubulin, actin, and nucleus in each stage were also decreased in vitrified and slow-frozen groups as compared to non-cryopreserved embryos.
CONCLUSIONS: Cryopreservation of mouse embryos by slow freezing had a more detrimental effect on the actin, tubulin, and nucleus structure of the embryos compared to vitrification. Vitrification is therefore superior to slow freezing in terms of embryonic cryotolerance.
Aims: This study aimed to explore the general public's perception toward electronic cigarette use. Public support toward electronic cigarette regulation was also examined.
Settings and Design: This was a Malaysian population-based survey.
Materials and Methods: Data were obtained from the National E-Cigarette Survey (NECS) 2016, which used a multistage stratified cluster sampling household survey representing all Malaysian adults aged 18 years old. A cross-sectional survey was conducted among a total of 4288 adults.
Statistical Analysis Used: Descriptive and logistic regression analysis.
Results: Majority were aged 25-44 years old (44%), completed at least secondary education (69%), of Malay ethnicity (73%), and married (68%). Majority (88.1%) have never used electronic cigarette. A quarter (25.5%) perceived electronic cigarette helps people quit cigarette smoking, whereas 20.3% perceived electronic cigarette helps people to maintain cigarette abstinence. Approximately 85% believed that electronic cigarette use does not help in improving breathing and coughing. Majority (91.8%) disagreed that electronic cigarettes should be allowed in places where tobacco smoking is banned. Thus, 63.4% agreed that electronic cigarette should be banned completely rather than regulated.
Conclusion: Majority of general public had negative perception about electronic cigarette use.
Methods: The current study was cross-sectional population-based and used a convenient sampling technique. Moreover, Lorenz's formula was used to calculate the sample size and the required sample size was 480. Data were collected through face-to-face interviews with a pre-validated questionnaire and the study was conducted in Kuala Lumpur (Malaysia). Descriptive statistics, cross-tabulation, and logistic regression were executed by using SPSS version 24.
Results: Out of 480 participants, 45.8% were polled male and the prevalence of SMA in this study was found to be 15.1%. The majority of participants 23.1% indicated that they practiced antibiotics at least once in the last six months. The commonly self-medicated antibiotics were amoxicillin-clavulanate 20.6%, ampicillin/cloxacillin 14.2%, and levofloxacin 8.3%. Moreover, 64.8% of participants indicated that they bought their antibiotics from pharmacies. Whereas, most of the participants practice antibiotics to save money 19.2% and time 23.1%. Findings from multivariate logistic regressions showed that predictors of SMA were male gender, (95% CI: 0.300-0.877) occupation (95% CI: 0.122-10.797), health insurance (95% CI: 0.025-0.472), and education (95% CI: 0.084-0.800).
Conclusion: The results of this study indicate that SMA persists among the community and education level has a significant impact on this behavior. Thus, concerning health management authorities should step in with developing legislation to stop this practice, and by implementing such interventions and policies to educate and to raise awareness about the risk of SMA for the future.
DESIGNS: Retrospective cross-sectional study.
SETTING: PMCare claims database from January 2016 to August 2019.
PARTICIPANTS: A total of 83,556 outpatient clinic visits involving 10,150 IIUM employees of the International Islamic University Malaysia (IIUM) to private general practitioners (GPs). During the study period, IIUM adopts the incentive structure of capping coverage at Ringgit Malaysia (RM) 45/outpatient visit (USD 10.58) to cover for consultation fees and medicine costs.
MAIN OUTCOME MEASURES: The monthly percentage change in the number of clinic visits, medicine costs, consultation fees and total costs between January 2016 and August 2019. A simple linear regression using Stata v15.1 was also performed to measure the association between the characteristics of the prescribed medicines and medicine charges.
RESULTS: The number of clinic visits per patient increased by 17% from January 2016 to August 2019, with consultation fees increasing by 113.9% and total costs by 7.9% per clinic visit per patient. Conversely, the cost of medicines and the number of medicines prescribed per clinic visit per patient decreased by 39.7% and 6.3%, respectively.
CONCLUSION: Within the incentive structure of capping the total amount of coverage per clinic visit, medicine costs were reduced by decreasing the number of medicines prescribed, to offset the increased consultation fees. This may create perverse incentives that affect medicine use with negative consequences for the health system and health insurers.
DESIGN: A 13-station OSCE was designed and implemented in the 2007-2008 academic year as part of the assessment methods for a clinical pharmacy course. The broad competencies tested in the OSCE included: patient counseling and communication, clinical pharmacokinetics (CPK), identification and resolution of drug-related problems (DRPs), and literature evaluation/drug information provision.
ASSESSMENT: Immediately after all students completed the OSCE, a questionnaire containing items on the clarity of written instructions, difficulty of the tasks, perceived degree of learning gained and needed, and the suitability of the references or literature resources provided was administered. More than 70% of the students felt that a higher degree of learning was needed to accomplish the tasks at the 2 DRP stations and 2 CPK stations and the majority felt the written instructions provided at the phenytoin CPK station were difficult to understand. Although about 60% of the students rated OSCE as a difficult form of assessment, 75% said it should be used more and 81% perceived they learned a lot from it.
CONCLUSION: Although most students felt that the OSCE accurately assessed their skills, a majority felt the tasks required in some stations required a higher degree of learning than they had achieved. This may indicate deficiencies in the students' learning abilities, the course curriculum, or the OSCE station design. Future efforts should include providing clearer instructions at OSCE stations and balancing the complexity of the competencies assessed.
METHODS: This cross-sectional study involved third- and fourth-year pharmacy students at the International Islamic University Malaysia. A validated self-administered questionnaire was distributed to students who had taken a vOSCE a week before.
RESULTS: Out of the 253 students who were approached, 231 (91.3%) completed the questionnaire. More than 75% of the participants agreed that the instructions and preparations were clear and helpful in familiarizing them with the vOSCE flow. It was found that 53.2% of the respondents were satisfied with the flow and conduct of the vOSCE. However, only approximately one-third of the respondents believed that the tasks provided in the vOSCE were more convenient, less stressful, and easier to perform than those in the conventional OSCE. Furthermore, 49.7% of the students favored not having a vOSCE in the future when conducting a conventional OSCE becomes feasible again. Internet connection was reported as a problem hindering the performance of the vOSCE by 51.9% of the participants. Students who were interested in clinical pharmacy courses were more satisfied than other students with the preparation and operation of the vOSCE, the faculty support, and the allocated time.
CONCLUSION: Students were satisfied with the organization and operation of the vOSCE. However, they still preferred the conventional OSCE over the vOSCE. These findings might indicate a further need to expose students to telehealthcare models.
