Designing and Conducting Randomized Controlled Trials: Basic Concepts for Educating Early Researchers in the Field of Clinical Nutrition.

Randomized controlled trials (RCTs) provide the best quality evidence to steer patient care in the field of clinical nutrition. However, designing and conducting an RCT, analyzing data, interpreting and reporting its findings is rather complex for young researchers working in the field of clinical nutrition. This review article attempts to educate early researchers by offering a simple step by step guide on planning the key aspects (randomization, allocation concealment, blinding, outcome measures) of a trial, and highlighting the practical considerations (ethical clearance, trial registry, patient recruitment, trial monitoring) to be kept in mind while conducting a trial contextualised to clinical nutrition settings.

Perceived barriers and facilitators for adherence to lifestyle prescription: Perspective of obese patients with non alcoholic fatty liver disease from north India.

BACKGROUND AND AIMS: This study aims to identify the barriers and facilitators faced by obese patients with NAFLD from north India, while undergoing lifestyle-modification. METHODS: 30 obese patients with NAFLD were interviewed regarding the barriers and facilitators to lifestyle change and responses were noted. Inductive thematic analysis was used. RESULTS: Eight themes under barriers (lack of family support, difficult intervention, work-related, financial, psychological, social, physical and infrastructure related) and four themes under facilitators (family support, intensive nature of intervention, psychological and physiological) were identified from the reponses. CONCLUSIONS: Personalized and socio-culturally appropriate counseling strategies may promote successful treatment outcomes among these patients.

Development of a self-assessment tool for resident doctors' communication skills in India

PURPOSE: Effective communication skills are essential for resident doctors to provide optimum patient care. This study was conducted to develop and validate a questionnaire for the self-assessment of resident doctors' communication skills in India. METHODS: This was a mixed-methods study conducted in 2 phases. The first phase consisted of questionnaire development, including the identification of relevant literature, focus group discussions with residents and experts from clinical specialties, and pre-testing of the questionnaire. The second phase involved administering the questionnaire survey to 95 residents from the Departments of Medicine, Emergency Medicine, Pediatrics, and Surgery at the All India Institute of Medical Sciences, New Delhi, India in April 2019. Internal consistency was tested and the factor structure was analyzed to test construct validity. RESULTS: The questionnaire consisted of 3 sections: (A) 4 items on doctor-patient conflicts and the role of communication skills in avoiding these conflicts, (B) 29 items on self-assessment of communication skills in different settings, and (C) 8 items on barriers to practicing good communication skills. Sections B and C had good internal consistency (Cronbach α: 0.885 and 0.771, respectively). Section C had a 2-factor solution, and the barriers were classified as 'training' and 'infrastructure' factors. CONCLUSION: This appears to be a valid assessment tool of resident doctors' communication skills, with potential utility for identifying gaps in communication skills and developing communication skills modules.

Utilization of Intraoperative Real-time Three-Dimensional Transoesophageal Echocardiography to Objectively Assess Improvement in Synchronization and Regional Wall Motion after Coronary Reperfusion.

It is well known that myocardial ischemia leads to Regional Wall Motion Abnormalities (RWMAs) and reversible depression of Left Ventricular (LV) systolic function. Transoesophageal Echocardiography (TEE) is an established tool for early diagnosis of new RWMAs. However, evaluation of RWMAs by echocardiography is largely qualitative and relies on visual assessment of wall segments. Evaluation of LV systolic function and Ejection Fraction (EF) is more reproducible and accurate with Real-Time 3D Echocardiography (RT3DE) as compared with two-dimensional and M-mode techniques. Primary advantages for RT3DE are fast and largely automated volumetric analysis of LV function and LV volumes, without geometric assumptions and risk of underestimating volumes in foreshortened views. This case illustrates the use of intraoperative RT3DE during coronary artery bypass surgery to objectively assess: LV systolic function with LV volumes and RWMAs and improvement in cardiac synchronization following coronary reperfusion.
