Purpose: The coronavirus disease 2019 (COVID-19) pandemic has adversely impacted medical education worldwide. However, its impact on the postgraduate medical thesis and dissertation work is still not evaluated. Through this study, we planned to find out the problems brought by the pandemic and likely alternatives and possible solutions to thrust the academic competence of postgraduate students. Methods: After obtaining institutional ethics committee approval, we sent a 13-item questionnaire to postgraduate medical students in India via various social media online platforms. Data on the impact of the COVID-19 pandemic on thesis work and alternatives/solutions to improve the research competence were collected on a Likert scale and analyzed. Results: We received a total of 398 responses out of which 377 entries were included for final analysis. The majority of participants (88%) reportedly had an adverse impact on the thesis work and out of 25% of the participants who recently submitted their around 45% had to do so without achieving the estimated sample size. The 6-month departmental review for thesis progress was seen in merely 28% of participants. Possible alternatives suggested were the maintenance of log books, task-based assessment of research methodology, departmental audits, and systematic reviews. Solutions suggested for improving the research competence of students were a compulsory research methodology curriculum, a biostatistics department in each institution, permission to conduct thesis work beyond submission time, exclusive time for research work, and financial incentives. Conclusion Modification in the research aspect of the current postgraduate medical education is the need of the hour and the pandemic has enlightened us regarding the current weaknesses.

This study is aimed at gaining insights into the brain site-specific proteomic senescence signature while comparing physiologically aged brains with aging-related dementia brains (for example, Alzheimer's disease (AD)). Our study of proteomic differences within the hippocampus (Hp), parietal cortex (pCx) and cerebellum (Cb) could provide conceptual insights into the molecular mechanisms involved in aging-related neurodegeneration. Using an isobaric tag for relative and absolute quantitation (iTRAQ)-based two-dimensional liquid chromatography coupled with tandem mass spectrometry (2D-LC-MS/MS) brain site-specific proteomic strategy, we identified 950 proteins in the Hp, pCx and Cb of AD brains. Of these proteins, 31 were significantly altered. Most of the differentially regulated proteins are involved in molecular transport, nervous system development, synaptic plasticity and apoptosis. Particularly, proteins such as Gelsolin (GSN), Tenascin-R (TNR) and AHNAK could potentially act as novel biomarkers of aging-related neurodegeneration. Importantly, our Ingenuity Pathway Analysis (IPA)-based network analysis further revealed ubiquitin C (UBC) as a pivotal protein to interact with diverse AD-associated pathophysiological molecular factors and suggests the reduced ubiquitin proteasome degradation system (UPS) as one of the causative factors of AD.

Midgut malrotation and incomplete rotation are common causes of neonatal intestinal obstruction. At end of 10 week of intrauterine life, cecum will be placed in subhepatic region temporarily and descends to right lower quadrant by eleventh week. Arrest of cecum in subhepatic region or undescended cecum is a rare congenital anomaly of mid gut. Usually, it remains asymptomatic and is diagnosed incidentally. If any pathology occurs in anomalous part, like appendicitis then the diagnosis and treatment will be challenging in all age groups. Variation in blood supply have also been reported with anomalies leading to iatrogenic injuries during colonoscopy and surgeries. Lack of knowledge of these rare variations may lead to delayed diagnosis of appendicitis leading to perforation and surgical emergencies. In the present case, we describe an undescended cecum and its associated variation in branching pattern of superior mesenteric artery.

Objective: Due to its comprehensive, reliable, and valid format, the objective structured clinical examination (OSCE) is the gold standard for assessing the clinical competency of medical students. In the present study, we evaluated the importance of the OSCE as a learning tool for postgraduate (PG) residents assessing their junior undergraduate students. We further aimed to analyze quality improvement during the pre-coronavirus disease (COVID) and COVID periods. Methods: This quality-improvement interventional study was conducted at the Department of Obstetrics and Gynecology. The PG residents were trained to conduct the OSCE. A formal feedback form was distributed to 22 participants, and their responses were analyzed using a five-point Likert scale. Fishbone analysis was performed, and the ‘plan-do-study-act’ (PDSA) cycle was implemented to improve the OSCE. Results: Most of the residents (95%) believed that this examination system was extremely fair and covered a wide range of clinical skills and knowledge. Further, 4.5% believed it was more labor- and resource intensive and time-consuming. Eighteen (81.8%) residents stated that they had learned all three domains: communication skills, time management skills, and a stepwise approach to clinical scenarios. The PDSA cycle was run eight times, resulting in a dramatic improvement (from 30% to 70%) in the knowledge and clinical skills of PGs and the standard of OSCE. Conclusion The OSCE can be used as a learning tool for young assessors who are receptive to novel tools. The involvement of PGs in the OSCE improved their communication skills and helped overcome human resource limitations while manning various OSCE stations.
