The beta2-adrenergic receptor gene polymorphism is a major determinant of bronchodilator response to albuterol. Future pharmacodynamic studies of beta2-agonists should include determination of 02-adrenergic receptor genotype.

BackgroundThere is substantial evidence to support the association between tuberculosis (TB) and tobacco smoking and that the smoking-related immunological abnormalities in TB are reversible within six weeks of cessation. Therefore, connecting TB and tobacco cessation interventions may produce significant benefits and positively impact TB treatment outcomes. However, no study has extensively documented the evidence of benefits of such integration. SCIDOTS Project is a study from the context of a developing nation aimed to determine this.MethodsAn integrated TB-tobacco intervention was provided by trained TB directly observed therapy short-course (DOTS) providers at five chest clinics in Malaysia. The study was a prospective non-randomized controlled intervention using quasi-experimental design. Using Transtheoretical Model approach, 120 eligible participants who were current smokers at the time of TB diagnosis were assigned to either of two treatment groups: conventional TB DOTS plus smoking cessation intervention (integrated intervention or SCIDOTS group) or conventional TB DOTS alone (comparison or DOTS group). At baseline, newly diagnosed TB patients considering quitting smoking within the next 30 days were placed in the integrated intervention group, while those who were contemplating quitting were assigned to the comparison group. Eleven sessions of individualized cognitive behavioral therapy with or without nicotine replacement therapy were provided to each participant in the integrated intervention group. The impacts of the novel approach on biochemically validated smoking cessation and TB treatment outcomes were measured periodically as appropriate.ResultsA linear effect on both 7-day point prevalence abstinence and continuous abstinence was observed over time in the intervention group. At the end of 6 months, patients who received the integrated intervention had significantly higher rate of success in quitting smoking when compared with those who received the conventional TB treatment alone (77.5% vs. 8.7%; p < 0.001). Furthermore, at the end of TB treatment (6 months or later), there were significantly higher rates of treatment default (15.2% vs. 2.5%; p = 0.019) and treatment failure (6.5% vs. 0%; p = 0.019) in the DOTS group than in the SCIDOTS group.ConclusionThis study provides evidence that connecting TB-tobacco treatment strategy is significant among TB patients who are smokers. The findings suggest that the integrated approach may be beneficial and confer advantages on short-term outcomes and possibly on future lung health of TB patients who quit smoking. This study may have important implications on health policy and clinical practice related to TB management among tobacco users.

Objectives. To assess bachelor of pharmacy students' overall perception and acceptance of an objective structured clinical examination (OSCE), a new method of clinical competence assessment in pharmacy undergraduate curriculum at our Faculty, and to explore its strengths and weaknesses through feedback. Methods. A cross-sectional survey was conducted via a validated 49-item questionnaire, administered immediately after all students completed the examination. The questionnaire comprised of questions to evaluate the content and structure of the examination, perception of OSCE validity and reliability, and rating of OSCE in relation to other assessment methods. Open-ended follow-up questions were included to generate qualitative data. Results. Over 80% of the students found the OSCE to be helpful in highlighting areas of weaknesses in their clinical competencies. Seventy-eight percent agreed that it was comprehensive and 66% believed it was fair. About 46% felt that the 15 minutes allocated per station was inadequate. Most importantly, about half of the students raised concerns that personality, ethnicity, and/or gender, as well as interpatient and interassessor variability were potential sources of bias that could affect their scores. However, an overwhelming proportion of the students (90%) agreed that the OSCE provided a useful and practical learning experience. Conclusions. Students' perceptions and acceptance of the new method of assessment were positive. The survey further highlighted for future refinement the strengths and weaknesses associated with the development and implementation of an OSCE in the International Islamic University Malaysia's pharmacy curriculum.

Objective. To implement and determine the effectiveness of an objective structured clinical examination (OSCE) to assess fourth-year pharmacy students' skills in a clinical pharmacy course. 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.

BackgroundCurrent studies on electronic cigarettes (ECs) have assessed the smoking cessation effectiveness and safety of EC among sole EC users. However, in Malaysia and elsewhere, most EC users also smoke conventional cigarettes (CCs). We aimed to investigate nicotine cessation for both ECs and CCs. Additionally, safety issues among sole EC and dual (EC and CC) users over a six-month period were reported.MethodsWe observed 218 sole Malaysian EC and dual users over 6 months from June 2015 to November 2015. Both groups underwent exhaled breath carbon monoxide and saliva cotinine analyses to verify their nicotine cessation from both EC and CC use. Adverse events and withdrawal symptoms were assessed based on self-reports.ResultsOnly 3.3% of observed users quit both ECs and CCs, whereas 20.5% quit smoking CCs. Quitting ECs and CCs was significantly higher among sole EC users (5 vs 2, respectively; OR: 5.62; P = 0.036) than it was among dual users, a result that was similar for CCs smoking (29 vs. 15; OR: 6.33; P ≤ 0.001). No severe health issues were reported over the entire study period.ConclusionThe rates of quitting CCs and ECs were higher in sole EC users than those in dual users. No serious health effects were reported over 6 months in either group. ECs may serve as a smoking cessation aid in Malaysia, but appropriate regulations are necessary to encourage sole EC use to ensure product quality. Large randomised clinical trials (RCTs) with a longer follow-up are required to better measure the effectiveness and safety of ECs use alone and in combination with CCs.

Electronic cigarettes (e-cigarettes) are a new method for the consumption of nicotine. A nationwide survey among 4288 Malaysian adults was conducted in 2016 to measure the prevalence and to describe the population characteristics of e-cigarette users. A complex sampling design was used, and data were collected using a face-to-face questionnaire. The overall prevalence of current, ever, former, and dual users of e-cigarettes in Malaysia were 3.2% (95% confidence interval [CI] = 2.5-4.1), 11.9% (95% CI = 10.5-13.5), 8.6% (95% CI = 7.5-9.8), and 2.3% (95% CI = 1.8-3.1), respectively. The prevalence of all type of e-cigarette use was higher in urban than in rural areas. Current e-cigarette users were likely to be younger, males, and with higher education level. Among current e-cigarette users, 74% (95% CI = 64-82) also smoked conventional cigarettes (dual user). E-cigarette use is prevalent in Malaysia. It is common among younger adults, males, and cigarette smokers.

ObjectivesTo assess the knowledge of physicians and clinical pharmacists about inappropriate prescribing for elderly patients, their confidence in prescribing for elderly patients, and their perceptions of barriers to appropriate prescribing in this population.MethodsA cross-sectional study using a validated 20-item questionnaire was conducted among physicians (n=78) and clinical pharmacists (n=45) working in the medical wards of two tertiary hospitals in Malaysia. Knowledge was assessed by six clinical vignettes which were developed based on Beers criteria and the STOPP/START criteria. Other domains of the study were investigated using a four-point or five-point Likert scale.ResultsOf the 82 participants who completed the questionnaire, 65% were physicians, 90.2% had never received training in geriatric medicine, and 70.8% estimated that 25% or more of their patients were elderly. Only six participants (7.3%) had ever used STOPP/START or Beers criteria when prescribing for elderly patients, and 60% of the respondents had never heard of either one of those criteria. The mean score (SD) for the knowledge part was 3.65 (1.46) points, and only 27 participants (22.9%) scored more than four out of a possible six points. Overall, 34% of the participants rated themselves as confident in prescribing for elderly patients, and this was significantly associated with their knowledge score (P=0.02). The mean number (SD) of barriers cited per participant was 6.88 (2.84), with polypharmacy being the most cited barrier.ConclusionsThe majority of the participants had inadequate knowledge and low confidence regarding recommending medications for elderly patients. Continuing education on geriatric pharmacotherapy may be of value for the hospital physicians and pharmacists.
