Abstract
ABSTRACT Pulmonary mucoepidermoid carcinoma (PMEC) is a rare pulmonary neoplasm. Although 18 F-FDG PET/CT has been shown to present with increased metabolic activity in PMEC, literature does not report increased somatostatin receptor expression in these tumors. We present the case of a 15-year-old boy where PMEC mimicked a typical carcinoid of the lung on DOTANOC PET/CT by showing significant uptake on 68 Ga-DOTANOC.

Abstract
Three-dimensional high-definition (3D HD) and ultra-high-definition (4 K HD) endovision systems are rapidly adopted in academic setting. However, transferability of laparoscopic skills acquired from these systems to two-dimensional high-definition (2D HD) endovision system is not known. Forty stereo-enabled surgical residents were randomized into two groups. They performed three standardized surgical tasks, Task 1(Peg transfer), Task 2(Precision touch on uneven surface) and Task 3(Surgical knotting on rubber tube) for 15 repetitions using either 3D HD or 4 K HD. Both groups then performed the same tasks using 2D HD for 5 repetitions. Their performances were evaluated for execution time (speed) and error scores (safety). The residents in 3D HD group performed all three tasks significantly faster than residents in 4 K HD group with comparable error scores. The time taken to complete the tasks on 2D HD were comparable between residents trained in 3D HD and 4 K HD in two out of three tasks (p = 0.027, P = 0.115, p = 0.368 in task 1, 2 and 3 respectively). However, in two out of three tasks, residents trained on 3D HD committed significantly more errors than residents trained on 4 K HD (p < 0.0001, p < 0.001 in task 1 and task 2 respectively). Skill acquired on 4 K HD seems transferable to 2D HD environment. Participants trained in 3D HD made more errors while performing the tasks in 2D HD. It may be prudent to offer additional training on 2D HD to residents trained on 3D HD for safer laparoscopic surgical practice.

Abstract
BACKGROUND Laparoscopic Heller's myotomy (LHM) is an established treatment for achalasia cardia. Anti-reflux procedures (ARP) are recommended with LHM to reduce the post-operative reflux though the optimal anti-reflux procedure is still debatable. This study reports on the long-term outcomes of LHM with Angle-of-His accentuation (AOH) in patients of achalasia cardia. METHODS One hundred thirty-six patients of achalasia cardia undergoing LHM with AOH between January 2010 to October 2021 with a minimum follow-up of one year were evaluated for symptomatic outcomes using Eckardt score (ES), DeMeester heartburn (DMH) score and achalasia disease specific quality of life (A-DsQoL) questionnaire. Upper gastrointestinal endoscopy, high resolution manometry (HRM) and timed barium esophagogram (TBE) were performed when feasible and rates of esophagitis and improvement in HRM and TBE parameters evaluated. Time dependent rates of success were calculated with respect to improvement in ES and dysphagia-, regurgitation- and heartburn-free survival using Kaplan-Meier analysis. RESULTS At a median follow-up of 65.5 months, the overall success (ES ≤ 3) was 94.1%. There was statistically significant improvement in ES, heartburn score and A-DsQoL score (p < 0.00001, p = 0.002 and p < 0.00001). Significant heartburn (score ≥ 2) was seen in 12.5% subjects with 9.5% patients reporting frequent PPI use (> 3 days per week). LA-B and above esophagitis was seen in 12.7%. HRM and TBE parameters also showed a significant improvement as compared to pre-operative values (IRP: p < 0.0001, column height: p < 0.0001, column width: p = 0.0002). Kaplan-Meier analysis showed dysphagia, regurgitation, and heartburn free survival of 75%, 96.2% and 72.3% respectively at 10 years. CONCLUSIONS LHM with AOH gives a lasting relief of symptoms in patients of achalasia cardia with heartburn rates similar to that reported in studies using Dor's or Toupet's fundoplication with LHM. Hence, LHM with AOH may be a preferred choice in patients of achalasia cardia given the simplicity of the procedure.

Abstract
Background Workplace violence (WPV) is a significant problem in both developed and developing countries, especially among healthcare workers. It has widespread implications for their overall health and well-being. Objective The study was conducted to assess the problem of violence among doctors and other healthcare workers in healthcare settings. Material and Methods A cross-sectional survey was conducted using a validated questionnaire from August 21 to September 18, 2021, based on purposive and snowball-sampling techniques for data collection. Appropriate statistical methods were applied to study the association between sociodemographics and characteristics of violence. Results A total of 601 responses were analyzed. The results showed that approximately 75% of the participants experienced violence in some form at their workplace. These episodes lead to a significant impact on the physical and mental health of these workers. Around one-third of the participants felt uncomfortable reporting these incidents. Some of the most common risk factors and mitigation strategies were also reported by the participants. Conclusion The findings of this study can be used by the legislators, administrators, and policymakers to develop strategies that can help in mitigating these episodes of violence for the better functioning of the healthcare system.

Abstract
INTRODUCTION Radioisotope and blue dye are standard agents for performing sentinel lymph node (SLN) biopsy in breast cancer. The paucity of nuclear medicine facility poses logistic challenge. This study evaluated performance of radioisotope & methylene blue (MB) with indocyanine green (ICG) and MB for SLNB. PATIENTS AND METHODS This randomized controlled trial was conducted from December 2019 to July 2022 comparing SLN identification proportions of radioisotope-blue dye [Group A] with dual dye (MB + ICG; Group B]. Secondary objective included time required and cost effectiveness of performing SLNB. Sample size of 70 (35 in each arm) was calculated. Upfront operable node negative early breast cancer was included in the study. Clinico-demographic data, number & type of SLN, time taken were noted. Cost analysis was done including the equipment, manpower & consumables. Chi-square/Fisher exact test was used to compare proportion between two groups. p value of less than 0.05 was considered to represent statistical significance. RESULTS Seventy patients randomized to either group were similar in clinico-demographic and tumor characteristics. SLN identification rate (IR) was 91.43% in group A and 100% in group B. Overall IR of MB, radioisotope and ICG were 91.43%, 91.43% and 100%, respectively. Mean number of SLNs identified were 3 in group A and 4 in group B. Median time required for SLNB was 12 min and 14 min in either group, respectively. Cost of performing SLNB was higher in Group B. CONCLUSION SLNB using dual dye is non-inferior to radioisotope-blue dye in upfront operable early breast cancer. Trial registration number Clinical Trial registry India CTRI/2020/02/023503.

Abstract
PURPOSE Penetrating abdominal trauma was traditionally managed by mandatory exploration, which led to high rates of non-therapeutic surgery and prolonged hospital stay. Diagnostic laparoscopy (DL) is a less-invasive alternative; however, it requires general anaesthesia and carries a potential risk of iatrogenic injuries. Contrast-enhanced computed tomography (CECT)-guided selective non-operative management (SNOM) may avoid surgery altogether, but there is apprehension of missed injury. Randomised trials comparing these two modalities are lacking. This study is aimed at comparing outcomes of these two management approaches. METHODS Hemodynamically stable patients with penetrating trauma to anterior abdominal wall were randomised in 1:1 ratio to DL or CECT-based management. Primary outcome was length of hospital stay (LOS). Secondary outcomes were rate of non-therapeutic surgery, complications, and length of intensive care unit (ICU) stay. RESULTS There were 52 patients in DL group and 54 patients in CECT group. Mean LOS was comparable (3 vs 3.5 days; p = 0.423). Rate of non-therapeutic surgery was significantly lower in CECT group (65.4 vs 17.4%, p = 0.0001). Rate of complications and length of ICU stay were similar. Selective non-operative management based on CECT findings was successful in 93.8% of patients; 2 patients had delayed surgery. CONCLUSION In patients with penetrating trauma to anterior abdominal wall, DL and CECT-based management led to comparable hospital stay. Significant reduction in non-therapeutic surgery could be achieved using a CECT-based approach. TRIAL REGISTRATION Clinical trials registry-India (CTRI/2019/04/018721, REF/2019/01/023400).

Abstract
INTRODUCTION Age adjusted Charlson comorbidity index (a-CCI) is an established scoring system to predict long-term mortality. However, its role in predicting 30-day post-operative outcome in general surgery patients is not well elucidated. METHODS This was a prospective observational study. Consecutive patients operated under general anaesthesia between January 2019 and December 2020 were enrolled. Their a-CCI was calculated and stratified as Grade 0 comorbidities (a-CCI score = 0), Grade A comorbidities (a-CCI score = 1 and 2) and Grade B comorbidities (a-CCI score ≥ 3). Post-operative complications were graded according to Clavien Dindo (CD) grading system and classified as minor complications (CD Grades I and II), major complications (CD Grades III-IV) and mortality (CD Grade V). Binary logistic regression and multi-nominal logistic regression analysis were done and relative risk ratios were calculated. RESULT A total of 925 patients were enrolled. The mean age was 42.75 (14-85 ± 10) years. 31% of our patients had complications within 30 days of surgery which included mortality in 2.7%. Compared with patients with Grade 0 comorbidities, the odds of getting complications is 1.2 times more in patients with Grade A comorbidities and 1.84 times more in patients with Grade B comorbidities (P = 0.205, 0.001 respectively). In comparison to patients with Grade 0 co-morbidities, risk of mortality is 3 and 17.86 times more in patients with Grade A and Grade B comorbidities (P = 0.121 and < 0.001 respectively). CONCLUSION a-CCI has clinical relevance in general surgical patients and can predict early post-operative outcome. It should be a part of our armamentarium for pre-operative assessment of surgical patients.

Abstract
BACKGROUND The study was conducted to assess the different components of communication skills and barriers to practicing good communication skills among resident doctors in a health care setting. MATERIALS AND METHODS A web-based cross-sectional survey was performed, and data were collected using a pre-validated questionnaire with a Cronbach's alpha (0.88). A total of 431 responses were statistically analyzed. Chi-square test was used to associate the socio-demographics and communication skills. Regression analysis was conducted to analyze the association between various communication domains and barriers, which were adjusted for potential confounders such as age and gender. RESULTS Resident doctors have differential levels of competencies in each domain of communication skills. Around two-thirds of the residents did not practice good communication skills while breaking the bad news and reported poor para-verbal skills. Some of the most common barriers to practicing good communication skills were found to be an infrastructural deficit, lack of time, and long working hours. These barriers significantly affected the communication skills such as para-verbal skills {[-0.32; P < 0.01; C.I (-0.54 to -0.09), [-0.27, P < 0.05, C.I (-0.54 to. 004)], [-0.32, P < 0.01, (0.07-0.56)]}, the ability to break bad news {[-0.42, P < 0.01, (-0.73 to -0.11)], [-0.35, P < 0.05, (-0.75 to -0.35)], [0.48, P < 0.01, (0.12-0.84)]}, and communication with patients/attendants {[0.39, P < 0.01, C.I (-0.71 to -0.06)], [-0.88, P < 0.001, C.I (-1.2 to -0.48)], [-0.88, P < 0.001, C.I (-1.2 to -0.48)]} after adjustment for confounding such as age and gender. CONCLUSION There is a scope for improvement in practicing good communication skills with patients, among the residents doctors in India. Structured modules for training and evaluation should be implemented in the medical curriculum.

Abstract
BackgroundNowadays 80% of internet users access health information online, with YouTube being the second most popular search website worldwide. This study was undertaken to assess the reliability and quality of videos pertaining to myositis on YouTube and identify lacunae in information material on the platform.ObjectivesThis study aims to assess the quality and profile of myositis information videos on YouTube, and to compare and delineate attributes of useful and not useful videos using standard metrics.MethodsA thorough search was carried out on YouTube using 9 search terms related to myositis. The inclusion criteria were primary English content related to myositis, acceptable audio-video quality, and multi-part videos to be considered as one, while duplicates and advertisements were excluded. The videos were classified as useful, not useful or misleading, and patient experiences (Figure 1).Figure 1.Flowchart of selection of YouTube videos for the studyReliability of the videos was determined using the 5-point modified DISCERN (mDISCERN) criteria and quality by the 5-point Global Quality Scale (GQS) and 4-point JAMA scoring system. Score-based usefulness was defined as mDISCERN >4 or GQS >4 or JAMA >3. All values are in median and IQR.ResultsOf 453 analyzed videos 74% and 2% provided useful and not useful information respectively. 24% were patient experiences, and 324 (71%) were intended specifically for patients while 313 (69%) were for healthcare providers and students. Nearly one-thirds (n=143) reported information related to treatment of myositis.Noteworthily, useful and not useful videos had similar views count. However, number of likes and daily viewership were higher for useful videos (p=0.024, p=0.046). Nearly half (47%) of useful videos were by professional medical societies/patient support groups while not useful ones were often by nonmedical media (38%).Useful videos had higher mDISCERN reliability scores [4(3-4) vs 2(1-3), p<0.001] and better quality on GQS [4.5 (3.5-5) vs 1 (1-2.8), p<0.001] and JAMA [3 (3-4) vs 2.25 (2-3), p=0.004]. Physician predicted usefulness was discordant with score-based usefulness(κ=0.129). However, GQS score emerged significant (p=0.008) for predicting video usefulness in multivariate analysis (Table 1).Table 1.Factors predicting usefulness of video in binary logistic regression.VariableB coefficientS.E.Exp (B) and 95% CIp valueIntended audience Anyone/General public-5.452.5860.004 (0.0-0.68)0.035Average GQS-2.861.0760.05 (0.007-0.47)0.008GQS Global Quality Scale. Exp (B) is odd’s ratio, p<0.05 is significantConclusionMajority of English YouTube videos on myositis provide useful information for patients, largely related to treatment of myositis. However, the dynamic nature of YouTube could potentially change this equation in the future and physicians should correct any misinformation identified in face-to-face meetings or teleconsultations. High quality useful videos, often predicted by validated scores and produced by professional medical societies should be promoted as the first line of content consumed.Disclosure of InterestsNone declared

Abstract
COVID-19 has been associated with myriad manifestations as well as adverse outcomes. One of the less commonly reported consequences of COVID-19 is the occurrence of secondary infections in patients suffering acutely from COVID-19 or in those recuperating. Secondary invasive fungal infections (IFIs) have also been observed earlier in other viral infections such as influenza, parainfluenza, and respiratory syncytial virus infections. Severe lung damage and immunologic derangement resulting from SARS-CoV-2 infection predispose to superinfections. Risk factors for secondary IFI includes immunologic derangement and immunoparalysis resulting from SARS-CoV-2 infection, neutropenia, or lymphopenia, poorly controlled diabetes, structural lung disease fungal colonization, and drugs such as corticosteroids or immunomodulators given as therapies for COVID-19. Invasive aspergillosis following COVID-19 is most commonly described fungal infection but other non-Aspergillus fungal infections (including mucormycosis) has also been reported. Herein we describe two interesting cases of secondary infections developing in patients beyond the acute phase of COVID-19 who had similar presentations but with different diagnoses and requiring different management strategies. Patient in case 1 developed COVID-19-associated subacute invasive pulmonary aspergillosis (SAIA) and patient in case 2 had COVID-19 associated pulmonary mucormycosis (CAPM). We have also described the various postulated immune-pathogenesis of the super-added fungal infections in COVID-19 patients.

Abstract
OBJECTIVE We evaluated effect of sequentially introducing four WHO-recommended interventions to promote hand-hygiene compliance in tertiary-care NICU. STUDY DESIGN Four dedicated research nurses directly observed doctors and nurses to record success in hand-hygiene opportunities at randomly selected NICU beds and randomly sampled time-slots in four phases (of 4-weeks each): I-Baseline, II-Self-directed learning; III-Participatory learning; IV-Closed-Circuit Television (CCTV); and V-CCTV-plus (with feedback). FINDINGS Hand-hygiene compliance changed from 61.8% (baseline) to 77% (end) with overall relative change: 24.6% (95% CI 18, 32; p value= 0.003); compared with preceding phase, relative changes of 21% (15, 28; <0.001), 4% (0, 8; 0.008), -10% (-13, -6; <0.001), and 10% (5, 15; <0.001) during phases II, III, IV, and V, respectively were observed. Rise in hand-hygiene compliance was higher for after-WHO-moments (12.7%; upto 2.5-folds for moment 5, <0.001) compared to before-WHO-moments (5.2%). Educational interventions, feedback and monitoring WHO moments can improve hand-hygiene compliance significantly among health-care providers in NICU.

Abstract
Esophageal leiomyomas are rare tumors which have been conventionally managed using open surgery. Only few reports describe the enucleation of large or circumferential leiomyoma successfully managed by thoracoscopy. We herein describe a case of a large circumferential esophageal leiomyoma successfully enucleated using thoracoscopy. An asymptomatic 28-year-old gentleman was diagnosed with a posterior mediastinal mass on a screening chest radiograph. On further investigations with computerized tomography scan and endoscopy, he was diagnosed to have a circumferential homogenous 7×5 cm submucosal lesion in the lower end of the esophagus. Magnetic resonance imaging was performed to rule out duplication cyst and positron emission scan to rule out malignancy in view of suspicious features on endoscopic ultrasound. The final provisional diagnosis was benign lesion of the esophagus. Biopsy of tumor was avoided preoperatively to decrease the chances of intraoperative mucosal injury. The patient was planned for a thoracoscopic enucleation. The tumor was enucleated with meticulous dissection in the submucosal plane with use of stay sutures and minimal use of cautery. There was a pinpoint mucosal perforation which was repaired. The integrity of repair was checked using methylene blue insufflation test and endoscopy. The patient had an uneventful recovery with postoperative gastrografin showing no leak or stricture. Conclusively, a large esophageal leiomyoma may be safely enucleated thoracoscopically with meticulous dissection.

Abstract
Introduction: Three-dimensional (3D), high-definition (HD), and ultra-high-definition (4K HD) are recent additions over regular HD technology for laparoscopic surgery. The aim of this study was to evaluate the learning pattern of these systems on standardized phantom tasks. Methodology: Forty-five stereo-enabled resident doctors were randomly assigned into three groups. They performed three validated tasks, precision touch on flat surface, precision touch on uneven surface, surgical knot on rubber tube using either two-dimensional (2D) HD, 3D HD, or 4K HD Endovision systems. Each task was repeated 20 times. Data from four consecutive repetitions were pooled to make five blocks. Split group analysis by comparing the consecutive blocks in execution time and errors were made to see the learning pattern. A significant difference was accepted as continuous learning while no significant difference was accepted as learning stabilization. Result: Operating time was stabilized in two tasks after third block in 2D HD, one task after fourth block in 4K HD. There was continuous learning in all tasks with 3D HD. The 3D HD group was significantly faster than 2D HD and 4K HD in most of the tasks on fifth block. The error scores were similar between the consecutive blocks in 4K HD. It was stabilized after second block in 2D HD group and third block on 3D HD. Conclusion: The 3D HD Endovision system has more potential of faster execution of a task, but need more practice to reach similar safety profile. The 4K HD reached the safety plateau with minimal repetitions.

Abstract
Background The 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. Methods In 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. Results Thirty 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. Conclusion ERAS protocol, when implemented in patients undergoing laparotomy for trauma, has decreased duration of hospital stay with no additional complications. Level of evidence Level 1, randomized controlled trial, care management. Trial registration number Clinical Trials Registry of India (CTRI/2019/06/019533).

Abstract
BACKGROUND AND PURPOSE Infarct volume is an important predictor of clinical outcome in acute stroke. We hypothesized that the association of infarct volume and clinical outcome changes with the magnitude of infarct size. MATERIALS AND METHODS Data were derived from the Safety and Efficacy of Nerinetide in Subjects Undergoing Endovascular Thrombectomy for Stroke (ESCAPE-NA1) trial, in which patients with acute stroke with large-vessel occlusion were randomized to endovascular treatment plus either nerinetide or a placebo. Infarct volume was manually segmented on 24-hour noncontrast CT or DWI. The relationship between infarct volume and good outcome, defined as mRS 0-2 at 90 days, was plotted. Patients were categorized on the basis of visual grouping at the curve shoulders of the infarct volume/outcome plot. The relationship between infarct volume and adjusted probability of good outcome was fitted with linear or polynomial functions as appropriate in each group. RESULTS We included 1099 individuals in the study. Median infarct volume at 24 hours was 24.9 mL (interquartile range [IQR] = 6.6-92.2 mL). On the basis of the infarct volume/outcome plot, 4 infarct volume groups were defined (IQR = 0-15 mL, 15.1-70 mL, 70.1-200 mL, >200 mL). Proportions of good outcome in the 4 groups were 359/431 (83.3%), 219/337 (65.0%), 71/201 (35.3%), and 16/130 (12.3%), respectively. In small infarcts (IQR = 0-15 mL), no relationship with outcome was appreciated. In patients with intermediate infarct volume (IQR = 15-200 mL), there was progressive importance of volume as an outcome predictor. In infarcts of > 200 mL, outcomes were overall poor. CONCLUSIONS The relationship between infarct volume and clinical outcome varies nonlinearly with the magnitude of infarct size. Infarct volume was linearly associated with decreased chances of achieving good outcome in patients with moderate-to-large infarcts, but not in those with small infarcts. In very large infarcts, a near-deterministic association with poor outcome was seen.

Abstract
In industrial foundries, raw metal is heated almost up to its melting point and then passed through the rolling mill to mould it into a desired shape. Contact with hot machinery or the hot metal can cause severe deep burns. When such thermal injury involves the abdominal wall, complex bowel injury can occur, leading to life-threatening abdominal sepsis. We report successful management of a patient with abdominal wall defect and multiple open fistulae. Severe thermal injury of the anterior abdominal wall may be associated with latent bowel injuries and abdominal compartment syndrome. A low threshold for surgery and re-look surgery may prevent complications.

Abstract
Objectives Dolutegravir (DTG) is widely recommended within three‐drug regimens. However, similar efficacy and tolerability have also been achieved with DTG within two‐drug regimens in clinical trials. This study evaluated the real‐world effectiveness and discontinuations in people living with HIV‐1 (PLHIV) switching to DTG with lamivudine (3TC) or rilpivirine (RPV). Methods This was a one‐arm meta‐analysis utilizing data from a systematic literature review. Data from real‐world evidence studies of DTG + RPV and DTG + 3TC were extracted, pooled and analysed. The primary outcome was the proportion of patients with viral failure (VF; ≥ 50 copies/mL in two consecutive measurements and/or ≥ 1000 copies/mL in a single measurement) at week 48 (W48) and week 96 (W96). Other outcomes included virological suppression (VS; < 50 copies/mL) and discontinuations (W48 and W96). Estimates were calculated for VF, VS as per snapshot (VSS) and on treatment analysis (VSOT), and discontinuations. Results Pooled mean estimates of VF for DTG + 3TC and DTG + RPV were 0.8% [95% confidence interval (CI): 0.4–1.3] and 0.6% (95% CI: 0.0–1.6), respectively, at W48. VSS rate at W48 was 85.0% (95% CI: 82.3–87.5) for DTG + 3TC regimen and 92.4% (95% CI: 85.0–97.7) in the DTG + RPV regimen. The DTG + 3TC and DTG + RPV regimens led to discontinuations in 13.6% (95% CI: 11.1–16.2) and 7.2% (95% CI: 2.1–14.4) of patients, respectively, at W48. Similar results were observed at W96. Conclusions Treatment with DTG + 3TC or DTG + RPV in clinical practice provides a low rate of VF and a high rate of VS when initiated in virologically suppressed PLHIV with diverse backgrounds.

Abstract
Invitro maturation (IVM) of oocytes is a crucial step and is directly related to better embryo production in buffaloes. Therefore, we planned to study gene expression of GDF9, HAS2, SPRY1, ARHGAP22, COL18A1, and GPC4 genes in IVM and immature cumulus–oocyte complexes (COCs). The COCs were recovered from follicles of slaughter origin ovaries of native buffaloes. COCs were observed under stereo zoom microscope and categorized in four grades according to morphology. Of the four grades, the first three grade COCs were considered and randomly allotted in two groups: immature treatment group (n=263) and IVM treatment group (n=272). IVM of COCs was carried out in 100-μL drops of BO-IVM medium overlaying embryo tested oil in a 35-mm petri dish under 5% CO2 in a 39.0°C incubator for 24h. Cumulus of COCs of both groups were removed by treating with 0.25% trypsin, and oocytes were stored in RNALater for future use. The expression of genes was evaluated using quantitative PCR, and the relative expression of each gene was calculated using the ΔΔCt method with efficiency correction. The logarithmic transformation of fold change (log2FC) of each candidate gene in the IVM oocyte group was computed against the immature oocyte group based on the observed cycle threshold values. Appropriate standard deviations were determined based on the observed deviations among the triplicates. The expression in the IVM treatment group of previously reported upregulated genes (GDF9, HAS2, SPRY1) was higher (up to 10-fold) compared with the immature treatment group (reference group). In the present study, relatively lower expression was observed for the other candidate genes (ARHGAP22, COL18A1, GPC4) in the bovine transcripts of oocyte, which were previously also reported as being downregulated.

Abstract
BACKGROUND Two-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. METHODS This 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. RESULTS The 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-TLX CONCLUSIONS: 3D 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.

Abstract
BACKGROUND Obesity is a major health problem, demonstrated to double the risk of colorectal cancer. The benefits of robotic colorectal surgery in obese patients remain largely unknown. This meta-analysis evaluated the clinical and pathological outcomes of robotic colorectal surgery in obese and non-obese patients. METHODS MEDLINE, Embase, Global Health, Healthcare Management Information Consortium (HMIC) and Midwives Information and Resources Service (MIDIRS) databases were searched on 1 August 2018 with no language restriction. Meta-analysis was performed according to PRISMA guidelines. Obese patients (BMI 30 kg/m2 or above) undergoing robotic colorectal cancer resections were compared with non-obese patients. Included outcome measures were: operative outcomes (duration of surgery, conversion to laparotomy, blood loss), postoperative complications, hospital length of stay and pathological outcomes (number of retrieved lymph nodes, positive circumferential resection margins and length of distal margin in rectal surgery). RESULTS A total of 131 full-text articles were reviewed, of which 12 met the inclusion criteria and were included in the final analysis. There were 3166 non-obese and 1420 obese patients. A longer duration of surgery was documented in obese compared with non-obese patients (weighted mean difference -21·99 (95 per cent c.i. -31·52 to -12·46) min; P < 0·001). Obese patients had a higher rate of conversion to laparotomy than non-obese patients (odds ratio 1·99, 95 per cent c.i. 1·54 to 2·56; P < 0·001). Blood loss, postoperative complications, length of hospital stay and pathological outcomes were not significantly different in obese and non-obese patients. CONCLUSION Robotic surgery in obese patients results in a significantly longer duration of surgery and higher conversion rates than in non-obese patients. Further studies should focus on better stratification of the obese population with colorectal disease as candidates for robotic procedures.

Abstract
INTRODUCTION Remote wireless monitoring is a new technology that allows the continuous recording of ward patients' vital signs, supporting nurses by measuring vital signs frequently and accurately. A case series is presented to illustrate how these systems might contribute to improved patient surveillance. METHODS AND RESULTS Five hospitals in three European countries installed a remote wireless vital signs monitoring system on medical or surgical wards. Heart rate, respiratory rate and temperature were measured by the system every 2 min. Four cases of (paroxysmal) atrial fibrillation are presented, two cases of sepsis and one case each of pyrexia, cardiogenic pulmonary edema and pulmonary embolisms. All cases show that the remote monitoring system revealed the first signs of ventilatory and circulatory deterioration before a change in the trends of the respective values became obvious by manual vital signs measurement. DISCUSSION This case series illustrates that a wireless remote vital signs monitoring system on medical and surgical wards has the potential to reduce time to detect deteriorating patients.

Abstract
PURPOSE Repair of giant paraoesophageal herniae (GPEH) is technically challenging and requires significant experience in advanced foregut surgery. Controversy continues on suture versus mesh cruroplasty with the most recent systematic review and meta-analysis putting the onus on the operating surgeon. Study aim was to review whether the biological prosthesis (non-cross-linked bovine pericardium and porcine dermis) and the technique adopted for patients with GPEH had an influence on clinical and radiological recurrences. METHOD A retrospective analysis of a prospectively collected data of 60 consecutive patients with confirmed 5 cm hiatus hernia and ≥ 30% stomach displacement in the thorax that were operated in the upper gastrointestinal unit of a large district general hospital between September 2010 and August 2017. Pre and post-surgery Gastro-Oesophageal Reflux Disease Questionnaire [(GORD-HRQOL)] and a follow up contrast study were completed. RESULTS 60 included 2 (3%) and 58 (97%) emergency and elective procedures respectively with a male: female ratio of 1:3, age 71* (Median) (42-89) years, BMI 29* (19-42) and 26 (43%) with ASA III/IV. Investigations confirmed 46* (37-88) mm and 42* (34-77) mm transverse and antero-posterior hiatal defect respectively with 60* (30-100)% displacement of stomach into chest. Operative time and length of stay was 180* (120-510) minutes and 2* (1-30) days respectively. One (2%) converted for bleeding and 2 (3%) peri-operative deaths. Five (8%), 5 (8%) and 4 (7%) have dysphagia, symptomatic and radiological recurrences respectively. GORD-HRQOL recorded preoperatively was 27* (10-39) dropping significantly postoperatively to 0* (0-21) (P < 0.005) with 95% patient satisfaction at a follow up of 60* (36-84) months. CONCLUSIONS Our technique of laparoscopic GPEH repair with biological prosthesis is safe with a reduced symptomatic and radiological recurrence and an acceptable morbidity and mortality.

Abstract
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.

Abstract
Considering the need for discovery of new antiviral drugs, in view to combat the issue of resistance particularly to anti-influenza drugs, a series of 2'-amino, 3'-amino and 2', 4'-dihydroxy chalcone derivatives were designed. Structure-based drug design was used to design inhibitors of influenza virus - H1N1 neuraminidase enzyme. These were further optimized by a combination of iterative medicinal chemistry principles and molecular docking. Based on the best docking scores, some chalcone derivatives were synthesized and characterized by infrared spectroscopy (IR) and proton nuclear magnetic resonance (NMR). The molecules were evaluated for their anti-influenza action against influenza A/Pune isolate/2009 (H1N1) virus by in vitro enzyme-based assay (neuraminidase inhibition assay). We have then selected few of them for multinuclear NMR studies, 31P NMR, in order to probe the molecular mechanism of their antiviral action. Reasonably good correlation between docking scores; anti-influenza activity; and 31P NMR results were observed. The computational predictions were in consensus with the experimental results. It was observed that among tested compounds, derivative 1A, viz. 2', 4'-dihydroxy-4-methoxy chalcone, showed highest activity (IC50 = 2.23 μmol/l) against the virus under study. This derivative 1A can be explored further to provide a future therapeutic option for the treatment and prophylaxis of H1N1 viral infections.

Abstract
Background Integrated curriculum enhances students' learning and the retention of knowledge. At Patan Academy of Health Sciences, integrated organ system based curriculum is used with Problem Based Learning as the principle teaching learning method to foster students' learning. In addition, other approaches of integration were under taken such as integrated assessment; logical arrangement teaching learning methods (lectures and practicals); joint effort of faculty in curriculum planning and delivery; conducive environment to foster hidden curriculum. This study describes the perception of faculty and students on integration characteristics of Basic Science curriculum. Objective To measure the integration characteristics of Basic Science Curriculum. Method Tool was developed to measure integration characteristics of Basic Science Curriculum and ensure whether such planned integration has been achieved. Mixed method was used to measure the perception of the integration characteristics i) quantitatively by questionnaire survey to faculty and students ii) qualitatively by in-depth interview of students. Result Both faculty and students perceived that all the blocks in Basic Science was well integrated in the quantitative questionnaire survey. But, in the in-depth interview, students perceived integration of curriculum in organ system blocks were better integrated compared to Principle of Human Biology blocks where fundamentals of basic science disciplines were delivered. Students reflected that Problem Based Learning not only integrated Basic Science disciplines but also with clinical sciences and the social context. But, students perceived that Community Health Sciences curriculum was not so well integrated with Basic Science subjects. Conclusion Overall, this study showed that planned integration in Basic Science curriculum was successfully executed during curriculum implementation.

Abstract
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.

Abstract
Blazars are active galactic nuclei, which are powerful sources of radiation whose central engine is located in the core of the host galaxy. Blazar emission is dominated by non-thermal radiation from a jet that moves relativistically towards us, and therefore undergoes Doppler beaming. This beaming causes flux enhancement and contraction of the variability timescales, so that most blazars appear as luminous sources characterized by noticeable and fast changes in brightness at all frequencies. The mechanism that produces this unpredictable variability is under debate, but proposed mechanisms include injection, acceleration and cooling of particles, with possible intervention of shock waves or turbulence. Changes in the viewing angle of the observed emitting knots or jet regions have also been suggested as an explanation of flaring events and can also explain specific properties of blazar emission, such as intra-day variability, quasi-periodicity and the delay of radio flux variations relative to optical changes. Such a geometric interpretation, however, is not universally accepted because alternative explanations based on changes in physical conditions-such as the size and speed of the emitting zone, the magnetic field, the number of emitting particles and their energy distribution-can explain snapshots of the spectral behaviour of blazars in many cases. Here we report the results of optical-to-radio-wavelength monitoring of the blazar CTA 102 and show that the observed long-term trends of the flux and spectral variability are best explained by an inhomogeneous, curved jet that undergoes changes in orientation over time. We propose that magnetohydrodynamic instabilities or rotation of the twisted jet cause different jet regions to change their orientation and hence their relative Doppler factors. In particular, the extreme optical outburst of 2016-2017 (brightness increase of six magnitudes) occurred when the corresponding emitting region had a small viewing angle. The agreement between observations and theoretical predictions can be seen as further validation of the relativistic beaming theory.

Experiments have been carried out using the deposition-based Direct Thoron Progeny Sensors (DTPS) in a thoron experimental house. The objective was to study the thoron decay product characteristics such as the deposition velocities, spatial variability and dependence on aerosol particle concentrations. Since the deposition velocity is an important characteristic in the calibration of the DTPS, it is very important to study its dependence on aerosol concentration in a controlled environment. At low aerosol concentration (1500 particles/cm3) the mean effective deposition velocity was measured to be 0.159 ± 0.045 m h-1; at high aerosol concentration (30 000 particles/cm3) it decreased to 0.079 ± 0.009 m h-1. The deposition velocity for the attached fraction of the thoron decay products did not change with increasing aerosol concentration, showing measurement results of 0.048 ± 0.005 m h-1 and 0.043 ± 0.014 m h-1, respectively. At low particle concentration, the effective deposition velocity showed large scattering within the room at different distances from center. The attached fraction deposition velocity remained uniform at different distances from the wall. The measurements in the thoron experimental house can be used as a sensitivity test of the DTPS in an indoor environment with changing aerosol concentration. The uniform spatial distribution of thoron decay products was confirmed within the experimental house. This indicates that direct measurement of thoron decay product concentration should be carried out instead of inferring it from thoron gas concentration, which is very inhomogeneous within the experimental house.
