Background and aimsGiven the multifactorial nature of obesity, there is current interest on Korean medicine (KM) for weight loss. This survey aimed to investigate current practice patterns of KM treatment for obesity among doctors.MethodsA questionnaire on clinical practice patterns of KM treatment for obesity was constructed and distributed to 21,788 KM doctors (KMDs). The questionnaire was consisted of respondent characteristics, state of treated patient, diagnosis, treatment, and usage pattern of herbal medicine for obesity.ResultsA total of 4.9% of KMDs (n = 1,084/21,788) validly completed the survey. Patients with Obesity Class I (25 ≤ Body mass index (BMI) ≤ 29.9) are the most common in KM clinics. Bioelectric impedance and KM Obesity Pattern Identification Questionnaire were routinely used for diagnosis. The average treatment duration was 4.16 weeks, and patients visited on an average 4.25 times per month for treatment. Herbal medicine is the most commonly used for obesity treatment by KMDs, and Taeeumjowui-tang was the most frequently prescribed. Ephedrae Herba, which is identified as the most used herbs for weight loss, was prescribed 5.18 ± 2.7 g/day at minimum and 10.06 ± 4.23 g/day at maximum. A total of 62.9% of responded KMDs had ever a patient with uncomfortable symptoms due to Ephedrae Herba use, neuropsychiatric events were the most common symptoms, followed by gastrointestinal events.ConclusionTaken together, this study provides information on real clinical practice patterns of KM including patients, diagnosis, treatments, and herbal medicine for obesity.

There is a paucity of research on the issue of alcohol provocation in the medical field. While studies have been performed concerning alcohol abuse among students, no studies have concentrated on alcohol provocation among medical professionals. Therefore, it is essential to look at the underlying factors that may influence alcohol use by medical professionals. A qualitative study using focus groups was conducted to construct themes depicting medical professionals' experiences of alcohol provocation. Physicians (n = 32) and residents (n = 29) were recruited from a large teaching hospital in Taiwan. The volunteers included both subjects and instigators of alcohol provocation (individuals being pressured to drink and those who exert such pressure on others). A questionnaire on their alcohol use was used to quantitatively assess the prevalence of alcohol consumption and inebriation. The participants were then interviewed separately in groups. All interview data were recorded, transcribed and analysed thematically. A notable prevalence of recent alcohol consumption was observed in both the physicians (n = 18, 56%) and residents (n = 17, 59%). Three prominent themes were identified and summarized: (1) Social drinking in the Taiwanese medical profession (2) Workplace hierarchy and changes in drinking culture, and (3) Influence on the medical profession. The behaviour of alcohol provocation among these medical professionals was revealed with its underlying factors of specific cultural norms, workplace hierarchy and social expectations. An understanding of alcohol provocation helps increase the awareness of adverse consequences associated with alcohol provocation, encourage medical professionals to avoid inappropriate drinking behaviors, and reduce the risk of compromising medical professionalism.

BackgroundAlthough randomized trials provide a high level of evidence regarding the efficacy of non-vitamin K oral anticoagulants (NOACs), the results of such trials may differ from those observed in day-to-day clinical practice.AimsTo compare the risk of stroke/systemic embolism (S/SE) and major bleeding (MB) between NOAC and warfarin in clinical practice.MethodsPatients with non-valvular atrial fibrillation (NVAF) who started warfarin/NOACs between January 2015 and November 2016 were retrospectively identified from Korea's nationwide health insurance claims database. Using inpatient diagnosis and imaging records, the Cox models with inverse probability of treatment weighting using propensity scores were used to estimate hazard ratios (HRs) for NOACs relative to warfarin.ResultsOf the 48,389 patients, 10,548, 11,414, 17,779 and 8,648 were administered apixaban, dabigatran, rivaroxaban and warfarin, respectively. Many patients had suffered prior strokes (36.7%, 37.7%, 31.4%, and 32.2% in apixaban, dabigatran, rivaroxaban, and warfarin group, respectively), exhibited high CHA2DS2-VASc (4.8, 4.6, 4.6, and 4.1 in apixaban, dabigatran, rivaroxaban, and warfarin group, respectively) and HAS-BLED (3.7, 3.6, 3.6, and 3.3 in apixaban, dabigatran, rivaroxaban, and warfarin group, respectively) scores, had received antiplatelet therapy (75.4%, 75.7%, 76.8%, and 70.1% in apixaban, dabigatran, rivaroxaban, and warfarin group, respectively), or were administered reduced doses of NOACs (49.8%, 52.9%, and 42.8% in apixaban, dabigatran, and rivaroxaban group, respectively). Apixaban, dabigatran and rivaroxaban showed a significantly lower S/SE risk [HR, 95% confidence intervals (CI): 0.62, 0.54-0.71; 0.60, 0.53-0.69; and 0.71, 0.56-0.88, respectively] than warfarin. Apixaban and dabigatran (HR, 95% CI: 0.58, 0.51-0.66 and 0.75, 0.60-0.95, respectively), but not rivaroxaban (HR, 95% CI: 0.84, 0.69-1.04), showed a significantly lower MB risk than warfarin.ConclusionsAmong Asian patients who were associated with higher bleeding risk, low adherence, and receiving reduced NOAC dose than that provided in randomised controlled trials, all NOACs were associated with a significantly lower S/SE risk and apixaban and dabigatran with a significantly lower MB risk than warfarin.

BackgroundMyanmar faces a health security threat, with an increasing number of multidrug-resistant tuberculosis (MDR-TB) cases. Long delays in the initiation of treatment are a barrier to MDR-TB control.ObjectivesThe main objectives of this study were (1) to identify the determinants of delay in treatment initiation after MDR-TB diagnosis, and (2) to explore the effects of treatment delay on disease infectivity, severity, treatment adherence, and treatment outcomes.MethodsThis retrospective study reviewed 330 MDR-TB treatment cards for patients enrolled for treatment at Yangon Regional Tuberculosis Centre, in 2014.ResultsMedian treatment delay was 105 days, interquartile range (IQR) 106 (61-167) days; (51.5%) of patients experienced a long treatment delay (≥ 105 days). Regarding the determinants of treatment delay, this study identified important patient-healthcare system interaction factors. Significant risk factors of long treatment delay included female sex, age > 30 years, and prior contact with patients with MDR-TB. Patients with long treatment delays were significantly different from those with short delays, in terms of having high sputum smear grade, resistance to more than two main drugs (isoniazid and rifampicin), and long culture conversion time. In this study, delay in the initiation of treatment was associated with poor treatment outcome, but this was not statistically significant after adjusting for other risk factors. Median treatment-delay times were longer among patients with poor outcomes (144 days) than those with successful outcomes (102 days).ConclusionsPost-diagnosis delays in the initiation of treatment among MDR-TB patients were significantly long. The study results showed that inadequate MDR-TB treatment initiation center, centralization of treatment initiation, limitation of human resources, were health-system factors delaying timely treatment initiation and implementation of an effective TB-control program. Our findings highlight the need for immediate interventions to reduce treatment delay and improve treatment outcomes, including scaling up diagnostic capacity with Xpert MTB/RIF at township level, expansion of decentralized MDR-TB treatment initiation centers, ensuring a productive health workforce comprising trained health personnel, and providing health education and treatment-adherence counseling to patients and family members.
