Medical and educational techniques and approaches have evolved globally over the past few decades. The modern approach is more learner-centred, with a focus on the acquisition of skills. The recently implemented competency-based medical education (CBME) for the National Medical Commission (NMC) undergraduate course curriculum is also competency-based rather than an outcome-based traditional curriculum. It is vital to embrace innovative teaching-learning and educational strategies to achieve the aspiration of CBME. This article provides a list of some of the newer tools and their perceived advantages and challenges and serves as a guide for using these methods effectively to meet the objectives of CBME as proposed by the NMC. Virtual teaching, learning from digital resources, objective-structured practical and clinical examination, flipped classroom, case-based learning, serious gaming, simulation-based learning and learning from role-plays and portfolios emerged as novel instructional strategies.

This research paper examines the effect of different solution heat-treatment parameters (quenching media and aging time) on microstructure, mechanical and corrosion properties of Al–Cu–Mg alloy. Scanning electron microscopy and X-ray diffraction analysis results have shown that a precipitate phase [S phase (Al 2 CuMg)] gets formed in as-cast conditions, but undergoes dissolution during solution heat-treatment process. Water quenching after solution heat treatment does not allow the precipitates to get reformed because of the faster cooling rate. However, air cooling enables some precipitate phases to get formed due to its slow cooling rate. It has been observed that water-quenched samples exhibit higher hardness (100.6 ± 0.6 HV1) than as-cast (93.3 ± 0.5 HV1) and air-cooled (84.9 ± 0.7 HV1) samples. Increase in aging time is observed to reduce Vickers hardness from 74.4 ± 1 HV1 (for 2 h aging) to 67.1 ± 0.5 HV1 (for 7 h aging) in case of solution heat-treated samples. Corrosion resistance is observed to improve after the solution heat treatment due to the dissolution of precipitate phase forms an almost single phase solid solution. A combination of solution heat treatment and water quenching is found to increase compressive stress (484.6 MPa to 508.4 MPa) and decrease strain (40.4% to 31.0%) as compared to the as-cast alloy. It is due to the formation of solid solution by the atoms constituting the precipitate phase (S phase (Al 2 CuMg)) as it undergoes dissolution during solution heat treatment. After aging (at 170 °C for 2 h), compressive stress reduces to 456.8 MPa and strain increases to 36.3% as compared to solution heat-treated samples.

Data transparency has been an important aspect of medical research as it helps in enabling evidence-based decisions in medicine which leads to foster trust among the patients and research community alike. Currently, it is one of the key talking points owing to a number of initiatives taken by the pharmaceutical organizations, regulatory bodies, and the other decision enablers of the industry. Thanks to this, there are a number of ways by which a single piece of datum is available through multiple access points, namely, clinical trial disclosures (CTDs), clinical study reports (CSRs), plain language summaries, and scientific publications including abstracts, posters, and manuscripts, to name a few. This may pose a burden of documentation on the pharmaceutical organizations, demanding downsizing of medical writing documents. Since CTDs, CSRs, and other regulatory document are more or less template driven; there may not be much scope to interfere with their structure and submission timings. Scientific publications, on the other hand, provide the flexibility of presenting the clinical data that is typically not dependent on a particular format and timelines. The present paper discusses how the upcoming data transparency initiatives could affect the publication practices across the pharmaceutical industry and what could pharmaceutical companies do to get the maximum benefit out of the data transparency initiatives.

Objective: This study was conducted to evaluate the frequency and clinicopathologic correlates of human epidermal growth factor receptor 2 (HER-2)/neu and betacatenin (BC) oncoproteins in gastric adenocarcinoma and to seek correlation if any between their expression status. Materials and Methods: This cross-sectional analytical immunohistochemistry (IHC) study was performed on 50 cases of gastric adenocarcinoma. HER-2/neu immunoexpression was scored as per criteria by Ruschoff et al. as positive (3+), equivocal (2+), and negative (1+, 0). Aberrant BC expression was categorized as nuclear, cytoplasmic, and reduced membranous immunoexpression. Protein expression results of both oncoproteins were correlated with conventional clinicopathological parameters. Correlation between immunoexpression profiles of both proteins was also analyzed. P <0.05 was considered statistically significant. Results: HER-2/neu positivity (2 + and 3+) was seen in 94% of the cases; almost 60% had strong (3+) expression. All cases showed aberrant BC immunoexpression (any pattern) except 2 cases that revealed negative expression (a form of aberrant immunoexpression) and were removed from analysis due to a very small number. The pattern of BC expression was as follows: nuclear expression (38%), cytoplasmic expression (82%), reduced membranous expression (96%), no staining (4%) cases. HER-2/neu expression correlated with age. No significant correlation was found between any of the 2 oncoprotein immunoexpression and other clinicopathological parameters (P > 0.05). Concordance between protein expression of HER-2/neu and BC was seen in >93% cases, however, the correlation was not significant. Conclusion: HER-2/neu and BC oncoprotein expression are frequently dysregulated in gastric adenocarcinomas. The significance of pathways involving HER-2/neu and BC in gastric carcinogenesis should be explored.

BackgroundTwo-dimensional high-definition (2D HD) endovision system is preferred for laparoscopic surgery. Recently, new generation three-dimensional (3D) HD and ultra-HD (4K) endovision systems are introduced to improve the safety and efficacy of laparoscopic surgery. There is limited evidence on superiority of one technology over the others. This experimental trial was designed to evaluate 2D HD, 3D HD and 4K HD endovision systems in performance of standardized tasks.MethodsThis was a randomized, cross-over experimental study. Twenty-one surgical residents who were exposed to laparoscopic surgery were enrolled. Participants were randomly assigned into three groups. Each group performed standardised tasks i.e. peg transfer, precision cutting, navigating in space and intra-corporeal suturing using 2D HD, 4K HD and 3D HD endovision systems on a box trainer. Procedures were recorded as 2D HD videos and analysed later. Participant’s perceived workload was assessed using Surg-TLX questionnaire. Primary endpoints were execution time in seconds and error score. Secondary endpoint was workload assessment.ResultsThe 3D HD had shorter execution time compared to 2D HD and 4K HD in all tasks except precision cutting (p = 0.004, 0.03, 0.001, 0.001 and p = 0.002, 0.191, 0.006, 0.005 in peg transfer, precision cutting, navigating in space and intra-corporeal suturing respectively). The 4K HD was significantly faster than 2D HD only in navigating in space task (p = 0.002). The error score between 3D HD and 4K HD were comparable in all tasks. The 2D HD had significantly more error scores compared to 4K HD, 3D HD in peg transfer task (p = 0.005, 0.014, respectively). 3D HD had significantly less workload than 2D HD and 4K HD in most of the dimensions of Surg-TLXConclusions3D HD endovision system in comparison to 2D HD and 4K HD, may lead to faster execution without compromising safety of a task and is associated with less workload.

Increasing HER-2/neu resistance in gastric carcinoma has encouraged search for new biomarkers for targeted therapy. Cellular mesenchymal epithelial transition (C-MET) is one such tyrosine kinase inhibitor proposed for personalized salvage treatment. We determined frequency of C-MET gene copy number variation (CNV) by Fluorescent in-situ hybridization (FISH) in gastric adenocarcinoma (GAC) and sought its correlation with conventional clinicopathologic parameters. Dual-coloured FISH was done on 32 GAC cases. C-MET gene and centromere 7 signals were counted under fluorescent microscope and ratio was calculated for each case. Correlation between C-MET CNV and conventional clinic-pathologic parameters was done by Fischer exact test. CNV was identified in the form of amplification and polysomy (3.1% each) and associated with poorer prognostic parameters. Our pilot study highlights limited subset of patients that may benefit from anti-C-MET-targeted therapy and thus could be a novel biomarker for targeted intervention in GAC.

Publications in peer-reviewed journals as well as oral and poster presentations for scientific conferences comes under the purview of GPP3 guideline. The GPP3 has kept pace with the changes in publication practices and focusses on every burning aspect of publications. The present paper evaluates the purview of GPP3 guideline in context with the evolving role of medical writer (MW) in the present times. A MW plays an important role to in producing high quality authentic documents. The role of professional MW have previously been emphasised upon in previous versions of GPP guidelines, and have been instrumental in acknowledging role of MWs in medical publications and cementing their existence rather than them being termed as 'ghostwriters'. Additionally the paper focuses on evolving publication and research presentation standards with reference to other guidelines. The paper also focusses on clarity on reimbursements which is in contrast to other Acts (Sunshine Act). Most importantly, the expectations from subsequent guidelines are also discussed which may form basis of subsequent GPP guidelines.

BackgroundThe role of enhanced recovery after surgery (ERAS) has been established in elective operations. However, its role in emergency operations especially in trauma is under-recognized. The aim of this study was to explore the safety and efficacy of ERAS program in patients undergoing emergency laparotomy for trauma.MethodsIn this single-center study, patients who underwent emergency laparotomy after trauma were randomized to the ERAS protocol or conventional care. The ERAS protocol included early removal of catheters, early initiation of diet, use of postoperative prophylaxis and optimal usage of analgesia. The primary endpoint was duration of hospital stay. The secondary endpoints were recovery of bowel function, pain scores, complications and readmission rate.ResultsThirty patients were enrolled in each arm. The ERAS group had significant reduction in duration of hospital stay (3.3±1.3 vs. 5.0±1.7; p<0.01). Time to remove nasogastric tube (1.1±0.1 vs. 2.2±0.9; p<0.01), urinary catheter (1.1±0.1 vs. 3.5±1.6; p<0.01), and drain (1.0±0.2 vs. 3.7±1.6; p<0.01) was shorter in the ERAS group. In ERAS group, there was earlier initiation of liquid diet (1.1±0.1 vs. 2.3±1.0; p<0.01) and solid diet (2.1±0.1 vs. 3.6±1.3; p<0.01). The usage of epidural analgesia (63% vs. 30%; p=0.01), non-steroidal anti-inflammatory drugs (93% vs. 67%; p-0.02) and deep vein thrombosis prophylaxis (100% vs. 70%; p<0.01) was higher in the ERAS group. There was no difference in the recovery of bowel function (2.4±1.0 vs. 2.1±0.9; p=0.15), pain scores (3.2±1.0 vs. 3.1±1.1; p=0.87), complications (27% vs. 23%; p=0.99) and readmission rates (07% vs. 10%; p=0.99) between the two groups.ConclusionERAS protocol, when implemented in patients undergoing laparotomy for trauma, has decreased duration of hospital stay with no additional complications.Level of evidenceLevel 1, randomized controlled trial, care management.Trial registration numberClinical Trials Registry of India (CTRI/2019/06/019533).

The preoperative diagnosis of metastatic intestinal gastrointestinal stromal tumors (GIST) on cytology can be quite difficult at times. The present case characterizes the cytomorphological and immunocytochemical features of GIST, emphasizing the utility of fine-needle aspiration cytology (FNAC) in the evaluation of spindle cell tumors of gastrointestinal tract. An accurate and early diagnosis of GIST affects the treatment, primarily allowing the use of tyrosine kinase inhibitors in unresectable or metastatic cases. Presence of highly cellular fragments of spindle-to-oval cells with variable degree of pleomorphism, atypia, and necrosis supplemented by immunocytochemistry can render a cytological diagnosis of GIST in dilemmatic clinical situations. Our case highlights the diagnostic role of FNAC in the evaluation of a pelvic mass, which was clinicoradiologically misdiagnosed as ovarian carcinoma.
