Introduction Electronic cigarettes (e-cigarettes) are new smoking devices that have gained popularity recently. However, there is limited evidence on e-cigarette consumption in Malaysia. This study aims to determine the prevalence, risk factors and perception associated with e-cigarette use among those attending government hospitals and health clinics in Malaysia. Methods A cross-sectional hospital-based study was conducted in seven public hospitals and health clinics in Malaysia, which were selected through a twostage cluster sampling. A validated questionnaire was used to obtain data from the selected participants. Multivariable logistic regression was employed to determine the association between sociodemographics and perceptions of e-cigarette use. Results Almost three-quarters (73.6%; n=923/1254) of participants were aware of e-cigarettes and 13.2% (n=122/923) reported having ever used e-cigarettes. The prevalence was significantly higher among males (18.1%), smokers (21.4%), and younger age group 18–34 years (30.2%). Ever users showed favourable perceptions towards e-cigarettes compared to non-users (23.3% vs 30.14%, p

Background Worldwide, success rates for quitting smoking have been stagnant for decades despite advancement in pharmacotherapy. This study aims to test the effectiveness of a current smoking cessation treatment programme which implemented the modified UK Standard Treatment Plan based on the NHS Centre for Smoking Cessation and Training (NCSCT). Methods We conducted a double-arm, cluster-randomised controlled trial with 1-month, 3-months and 6-months follow-ups among newly registered smokers seeking quit smoking services from 19 public hospitals in Malaysia. Smokers were assigned to either NCSCT behaviour modification (treatment group; n = 330) or usual care (control group; n = 172). The intervention was administered by dedicated health staff trained in the NCSCT. Data was collected through self-administered questionnaires, with validation conducted using expired air carbon monoxide measurement. Intention-to-treat analysis was adopted, with smokers who did not return for follow-ups considered smoking. Multiple logistic regression was conducted using a backward elimination model to assess the repeated measures treatment effect of quitting for each point of follow-up. Results No significant difference was discernible between the intervention and control group other than: first cigarette of the day (p=0.05), urge to smoke (p=0.020), method of quitting (p=0.018) and COppm level (p=0.0234) at baseline. Compared to the control group, individuals from the intervention group were more likely to quit successfully at 1-month, 3-months and 6-months follow-up (OR=1.698, OR=3.395, and OR=3.506 respectively). Older individuals were also more likely to abstain at 1-month, 3-months and 6-months follow-up (OR= 1.015, OR=1.022 and OR=1.032 respectively). Individuals who smoked at home were less likely to abstain at 1-month, 3-months and 6-months follow-up (OR= 0.637, OR=0.592 and OR=0.385 respectively). Conclusions The modified Standard Treatment Programme appears superior to routine care practice in maintaining follow up sessions among smokers due to its structured and organized sessions.

Background: Myocardial injury after noncardiac surgery (MINS) was defined as prognostically relevant myocardial injury due to ischemia that occurs during or within 30 days after noncardiac surgery. The study’s four objectives were to determine the diagnostic criteria, characteristics, predictors, and 30-day outcomes of MINS. Methods: In this international, prospective cohort study of 15,065 patients aged 45 yr or older who underwent in-patient noncardiac surgery, troponin T was measured during the first 3 postoperative days. Patients with a troponin T level of 0.04 ng/ml or greater (elevated “abnormal” laboratory threshold) were assessed for ischemic features (i.e., ischemic symptoms and electrocardiography findings). Patients adjudicated as having a nonischemic troponin elevation (e.g., sepsis) were excluded. To establish diagnostic criteria for MINS, the authors used Cox regression analyses in which the dependent variable was 30-day mortality (260 deaths) and independent variables included preoperative variables, perioperative complications, and potential MINS diagnostic criteria. Results: An elevated troponin after noncardiac surgery, irrespective of the presence of an ischemic feature, independently predicted 30-day mortality. Therefore, the authors’ diagnostic criterion for MINS was a peak troponin T level of 0.03 ng/ml or greater judged due to myocardial ischemia. MINS was an independent predictor of 30-day mortality (adjusted hazard ratio, 3.87; 95% CI, 2.96–5.08) and had the highest population-attributable risk (34.0%, 95% CI, 26.6–41.5) of the perioperative complications. Twelve hundred patients (8.0%) suffered MINS, and 58.2% of these patients would not have fulfilled the universal definition of myocardial infarction. Only 15.8% of patients with MINS experienced an ischemic symptom. Conclusion: Among adults undergoing noncardiac surgery, MINS is common and associated with substantial mortality.

BACKGROUND: Dyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache. METHODS: A cross-sectional study was conducted in a secondary care setting. Clinical, psychological and health-related quality of life (HRQOL) data were compared between subjects with headache and controls (non-headache subjects). The impact of dyspepsia was analysed further in subjects with headache alone. RESULTS: 280 subjects (93 cases with headache and 187 matched controls) were recruited. The following baseline characteristics of subjects were as follows: mean age 45.0 ± 17.3 years, 57.0% females and ethnic distribution-Malaysian = 45 (48.4%), Chinese n = 24 (25.8%) and Indians n = 24 (25.8%). Headache sub-types among cases with headache were as follows: tension-type headache (TTH) n = 53 (57.0%) and migraine n = 40 (43.0%). Dyspepsia was more prevalent in cases with headache compared to controls (25.8% vs 12.8%, p = 0.011), and headache was independently associated with dyspepsia (OR 2.75, 95% CI 1.39-5.43). Among cases with headache, there was a trend towards a higher prevalence of dyspepsia in those with migraine (27.5%) compared to TTH (24.5%). Subjects with headache and dyspepsia, compared to those with headache alone, had a greater severity of headache symptoms (63.67 ± 22.85 mm vs 51.20 ± 24.0 mm VAS, p = 0.029). Overall HRQOL scores were lower in headache subjects with dyspepsia (EQ-5D summary score 0.82 ± 0.18 vs 0.90 ± 0.16, p = 0.037 and EQ-5D VAS 62.08 ± 17.50 mm vs 72.62 ± 18.85 mm, p = 0.018), compared to those without dyspepsia. CONCLUSION: Dyspepsia is associated with more severe headache symptoms and results in a lower HRQOL in patients with headache.

Background Somatic mutations of the epidermal growth factor receptor (EGFR) are reportedly associated with various responses in non-small cell lung cancer (NSCLC) patients receiving the anti-EGFR agents. Detection of the mutation therefore plays an important role in therapeutic decision making. The aim of this study was to detect EGFR mutations in formalin fixed paraffin embedded (FFPE) samples using both Scorpion ARMS and high resolution melt (HRM) assay, and to compare the sensitivity of these methods. Results All of the mutations were found in adenocarcinoma, except one that was in squamous cell carcinoma. The mutation rate was 45.7% (221/484). Complex mutations were also observed, wherein 8 tumours carried 2 mutations and 1 tumour carried 3 mutations. Conclusions Both methods detected EGFR mutations in FFPE samples. HRM assays gave more EGFR positive results compared to Scorpion ARMS.

Assessment of completeness of vagotomy has always been an irksome and time-consuming affair. The commonly employed test of insulin-induced hypoglycaemia (Hollander) is tedious, risky and associated with practical limitations and theoretical objections, which have resulted in its being replaced by the modified sham feed technique in some centres. The postprandial alkaline tide is attributed to HCO3− release consequent to H+ secretion. Any procedure which reduces acid secretion is expected to affect the postprandial urinary pH. This study was performed to evaluate the effect of vagotomy on the postprandial alkaline tide by measuring prevagotomy and postvagotomy fasting and postprandial urinary pH. The results show that postprandial urinary pH falls after vagotomy and this method may be used to assess the completeness of vagotomy. The proposed test is convenient and may be used as a screening method in the assessment of vagotomy and other acid reducing operative procedures, if further validated, by comparison with already established tests.
