Adjuvant therapy may improve overall survival in high-risk periampullary adenocarcinomas patients - A match-pair analysis from a multi-institutional cohort study (The MIPPAP study).

BACKGROUND: The role of adjuvant therapy in resected periampullary adenocarcinomas is equivocal due to contrasting data and limited prospective trials. METHODS: The Multicentre Indian Pancreatic & Periampullary Adenocarcinoma Project (MIPPAP), included data from 8 institutions across India. Of the 1679 pancreatic resections, 736 patients with T3/T4 and/or Node positive adenocarcinomas (considered as high risk for recurrence) were included for analysis. Three (adjuvant): one (observation) matching, using T3/T4 T staging, nodal positivity and ampullary subtype was performed by using the nearest neighbour matching method. RESULTS: Of 736 patients eligible for inclusion, 621 patients were matched of which 458 patients received adjuvant therapy (AT) (predominantly gemcitabine-based) and 163 patients were observed (O). With a median follow-up of 42 months, there was a statistical difference in overall survival in favour of patients receiving AT as compared to those on observation [68.7 months vs. 61.1 months, Hazard ratio: 0.73 (95% CI: 0.54-0.97); p = 0.03]. Besides AT, presence of nodal involvement (median OS: 65.4 months vs not reached; p = 0.04) predicted for inferior OS. CONCLUSIONS: The results of the match-pair analysis suggest that adjuvant therapy improves overall survival in periampullary adenocarcinomas at high risk of recurrence with a greater benefit in T3/T4, node-positive and ampullary subtypes.

Modulation of nuclear receptor 4A1 expression improves insulin secretion in a mouse model of chronic pancreatitis.

OBJECTIVES: Diabetes secondary to chronic pancreatitis (CP) presents clinical challenges due to insulin secretory defects and associated metabolic alterations. Owing to lack of molecular understanding, no pharmacotherapies to treat insulin secretory defects have been approved to date. We aimed to delineate the molecular mechanism of ß-cell dysfunction in CP. METHODS: Transcriptomic analysis was conducted to identify endocrine specific receptor expression in mice and human CP on microarray. The identified receptor (NR4A1) was overexpressed in MIN6 cells using PEI linear transfection. RNA-Seq analysis on NovaSeq 6000 of NR4A1 overexpressed (OE) MIN6 cells was performed to identify aberrant metabolic pathways. Upstream trigger for NR4A1OE was studied by InBio Discover and cytokine exposure. Downstream effect of NR4A1OE was examined by Fura2 AM based fluorometric and imaging studies of intracellular calcium. Mice with CP were treated with IFN-γ neutralizing monoclonal antibodies to assess NR4A1 expression and insulin secretion. RESULTS: Increased expression of NR4A1 associated with decreased insulin secretion in islets (humans: controls 9 ± 0.2, CP 3.7 ± 0.2, mice: controls 8.5 ± 0.2, CP 2.1 ± 0.1 µg/L). NR4A1OE in MIN6 cells (13.2 ± 0.1) showed reduction in insulin secretion (13 ± 5 to 0.2 ± 0.1 µg/mg protein/minute, p = 0.001) and downregulation of calcium and cAMP signaling pathways. IFN-γ was identified as upstream signal for NR4A1OE in MIN6. Mice treated with IFN-γ neutralizing antibodies showed decreased NR4A1 expression 3.4 ± 0.11-fold (p = 0.03), improved insulin secretion (4.4 ± 0.2-fold, p = 0.01), associated with increased Ca2+ levels (2.39 ± 0.06-fold, p = 0.009). CONCLUSIONS: Modulating NR4A1 expression can be a promising therapeutic strategy to improve insulin secretion in CP.

Assessing the Efficacy of a Novel Massive Open Online Soft Skills Course for South Asian Healthcare Professionals.

In healthcare professions, soft skills contribute to critical thinking, decision-making, and patient-centered care. While important to the delivery of high-quality medical care, soft skills are often underemphasized during healthcare training in low-and-middle-income countries. Despite South Asia's large population, the efficacy and viability of a digital soft skills curriculum for South Asian healthcare practitioners has not been studied to date. We hypothesized that a web-based, multilingual, soft skills course could aid the understanding and application of soft skills to improve healthcare practitioner knowledge, confidence, attitudes, and intent-to-change clinical practice.In September 2019 a needs assessment observing soft skills practices was conducted in several Indian states. We developed a communication-focused soft skills curriculum that comprised seven 10-minute video lectures, recorded in spoken English and Hindi. Participants consisted of any practicing healthcare professionals and trainees in select South Asian countries age 18 and over. Participant knowledge, confidence, attitudes, and intent-to-change clinical practice were evaluated using pre- and post-course tests and surveys. Statistical analyses were performed using STATA and SPSS.From July 26, 2021 to September 26, 2021, 5750 registered and attempted the course, 2628 unique participants completed the pre-test, and 1566 unique participants completed the post-test. Participants demonstrated small but statistically significant gains in confidence (𝑝<0.001), attitudes toward course topics relevance (𝑝<0.001), and intent-to-change clinical practice (𝑝<0.001). There was no statistically significant gain in knowledge. A digital soft-skills massive open online course for healthcare practitioners in South Asia could serve as a viable approach to improve the quality of soft skills training in low-to-middle income countries.

Tofacitinib use in ulcerative colitis: An expert consensus for day-to-day clinical practice.

Rising number of inflammatory bowel disease (IBD) cases in developing countries necessitate clear guidance for clinicians for the appropriate use of advanced therapies. An expert consensus document was generated to guide the usage of tofacitinib, a Janus kinase inhibitor, in ulcerative colitis. Tofacitinib is a useful agent for the induction and maintenance of remission in ulcerative colitis. It can be used in the setting of biological failure or even steroid-dependent and thiopurine refractory disease. Typically, the induction dose is 10 mg BD orally. Usually, clinical response is evident within eight weeks of therapy. In those with clinical response, the dose can be reduced from 10 mg BD to 5 mg BD. Tofacitinib should be avoided or used cautiously in the elderly, patients with cardiovascular co-morbidity, uncontrolled cardiac risk factors, previous thrombotic episodes and those at high risk for venous thrombosis or previous malignancy. Baseline evaluation should include testing for and management of hepatitis B infection and latent tuberculosis. Where feasible, it is prudent to ensure complete adult vaccination, including Herpes zoster, before starting tofacitinib. The use of tofacitinib may be associated with an increased risk of infections such as herpes zoster and tuberculosis reactivation. Maternal exposure to tofacitinib should be avoided during pre-conception, pregnancy, and lactation. There is emerging evidence of tofacitinib in acute severe colitis, although the exact positioning (first-line with steroids or second-line) is uncertain.

Indocyanine green guided sentinel lymph node biopsy may have a high sensitivity for early (T1/T2) colon cancer: A prospective study in Indian patients.

Objectives: Indocyanine green (ICG) dye guided near infrared fluorescence (NIR) imaging is a promising tool for mapping lymphatics. The aim of this study was to evaluate the role of ICG guided SLN biopsy in Indian colon cancer patients. Material and Methods: Forty-eight patients of clinically staged T1-T3 node negative colon cancer underwent laparoscopic/open resection. Patients received colonoscopic peritumoral submucosal ICG injections for laparoscopic (n= 32) and subserosal injections for open resections (n= 16) followed by the detection of SLN using NIR camera. SLNs underwent conventional hematoxylin and eosin (H & E) staging with additional serial sectioning and immunohistochemistry for pancytokeratin antibody (ultra-staging). Detection rate and upstaging rate were the primary end points. Results: Forty-eight patients were recruited. An average of 2.08 ± 1.27 SLNs were identified in 45 patients at a mean time of 8.2 ± 3.68 minutes with a detection rate of 93.75%. Mean age and mean BMI were 59.7 ± 12.54 years and 24.8 ± 4.09 kg/m2 , respectively. Eighteen patients had node positive disease, and SLN was false negative in four of these patients resulting in a sensitivity of 77.77% with a trend towards higher sensitivity for T1-T2 tumours (90% vs. 62.5%, p= 0.068). Upstaging rate was 10%. Negative predictive value (NPV) and accuracy of the procedure were 87.09% and 91.11%, respectively. Conclusion: ICG guided SLN biopsy can identify metastatic lymph nodes in colon cancer patients that can be missed on H & E staging with relatively higher sensitivity for early (T1/T2) tumours.

Circulating tumor DNA for monitoring colorectal cancer: A prospective observational study to assess the presence of methylated SEPT9 and VIM promoter genes and its role as a biomarker in colorectal cancer management.

Objectives: Methylation status of Septin9 (SEPT9) and vimentin (VIM) genes in circulating tumor DNA of colorectal cancer (CRC) patients is a promising bio-marker for the early detection of CRC. The aim of the present study was to identify the methylation status in promoter regions of the SEPT9 and VIM genes in a cohort of Indian patients with biopsy proven colorectal cancer. Material and Methods: Forty-five consecutive patients of colorectal cancer were recruited. 10 mL venous samples were collected from each patient and processed for isolation of cell-free DNA, bisulfite conversion of cell-free DNA, polymerase chain reaction (PCR) amplification and detection of SEPT9 and VIM genes. Results: Partial methylation in vimentin was present in 42.22% of the patients and 57.78% showed no methylation and none of the tumors had complete methylation. Only three (6.66%) patients showed complete methylation patterns in SEPT9 and the remaining 42 (93.33%) tumors showed partial methylation. Considering the two genes together, only three (6.66%) out of 45 showed complete methylation. The association of methylation patterns in both genes (complete, partial, and no methylation) with sex, age, T stage, N stage, M stage, CEA, histology, and location (right or left colon) were explored and none of these parameters were statistically significant. Conclusion: In our study, only 6.66% CRC patients showed hypermethylation and there was no association of methylation patterns in the both genes (complete, partial, and no methylation) with any of the parameters like age, sex, TNM stage, CEA, and histology.

Paediatric use of emergency medical services in India: A retrospective cohort study of one million children.

Background: Millions of children in low- and middle-income countries (LMICs) experience illness or trauma amenable to emergency medical interventions, but local resources are not sufficient to treat them. Emergency medical services (EMS), including ambulance transport, bridge the gap between local services and higher-level hospital care, and data collected by EMS could be used to elucidate patterns of paediatric health care need and use. Here we conducted a retrospective observational study of patterns of paediatric use of EMS services by children who used EMS in India, a leader in maternal and child EMS development, to inform public health needs and system interventions to improve EMS effectiveness. Methods: We analysed three years (2013-2015) of data from patients <18 years of age from a large prehospital EMS system in India, including 1 101 970 prehospital care records across 11 states and a union territory. Results: Overall, 38.3% of calls were for girls (n = 422 370), 40.5% were for adolescents (n = 445 753), 65.9% were from rural areas (n = 726 154), and most families were from a socially disadvantaged caste or lower economic status (n = 834 973, 75.8%). The most common chief complaints were fever (n = 247 594, 22.5%), trauma (n = 231 533, 21.0%), and respiratory difficulty (n = 161 120, 14.6%). However, transport patterns, including patient sex and age and type of destination hospital, varied by state, as did data collection. Conclusions: EMS in India widely transports children with symptoms of the leading causes of child mortality and provides access to higher levels of care for geographically and socioeconomically vulnerable populations, including care for critically ill neonates, mental health and burn care for girls, and trauma care for adolescents. EMS in India is an important mechanism for overcoming transport and cost as barriers to access, and for reducing the urban-rural gap found across causes of child mortality. Further standardisation of data collection will provide the foundation for assessing disparities and identifying targets for quality improvement of paediatric care.

Clinical outcomes in individuals hospitalized with SARS-CoV-2 Delta variant (B.1.617.2) who had been vaccinated with Covishield (ChAdOx1) and Covaxin (BBV-152).

Background: Covishield (ChAdOx) and Covaxin (BBV-152) are the mainstream vaccines against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) used in India and a few other countries. Objective: To assess the clinical outcomes of patients hospitalized with coronavirus disease 2019 (COVID-19) who had been vaccinated with either Covishield or Covaxin. Methods: This prospective, single-centre, observational cohort study of 1160 patients hospitalized with COVID-19 was conducted between April and June 2021. Severity of disease at admission and during hospitalization, requirement for intensive care unit (ICU) admission and ventilatory support, inflammatory markers (C-reactive protein, ferritin, lactate dehydrogenase, D-dimer), neutralizing antibody levels and mortality were assessed in vaccinated and unvaccinated patients. Results: More than 90% of patients in this study harboured the Delta variant (Pango lineage B.1.617.2) of SARS-CoV-2. Severity of disease at admission and during hospitalization (3.44% vs 7.51%; P=0.0032) and requirement for ICU admission and ventilatory support (2.83% vs 5.86%; P=0.0154) were significantly lower in vaccinated patients compared with unvaccinated patients. Vaccinated patients also had significantly (P<0.0001) higher antibody levels and lower inflammatory marker levels compared with unvaccinated patients. A subset of vaccinated, deceased patients mounted minimal antibody response ['non-responders': 4.53 (standard deviation 1.40) AU/mL]. Conclusion: These results demonstrate the effectiveness of Covishield and Covaxin against severe disease in patients hospitalized with COVID-19 with breakthrough infections caused by the Delta variant. Strategies targeting non-responders are desirable to minimize morbidity and mortality.

Is AVPU comparable to GCS in critical prehospital decisions? - A cross-sectional study.

BACKGROUND: Advanced Trauma Life Support field triage utilizes the Glasgow Coma Scale (GCS) to assess the level of consciousness. However, prehospital care providers in low- and middle-income countries (LMICs) often use the Alert, Verbal, Pain, and Unresponsive (AVPU) scale to assess the level of consciousness. This study aimed to determine whether prehospital AVPU categorization correlates with mortality rates in trauma victims, similarly to GCS. METHODS: In this cross-sectional study conducted between November 2015 and January 2016, we enrolled a convenience sample of prehospital trauma-related field activations. The primary outcome measure was the probability of death within 48 h for each category of AVPU. RESULTS: In a convenience sample of 4514 activations, 1606 (35.6%) met exclusion criteria, four did not have AVPU, and four did not have GCS, leaving 2900 (64.2%) trauma activations with both AVPU and GCS available for analysis. Forty-eight-hour follow-up data were available for 2184 (75.3%) activations out of these 2900. The 48-h mortality rates for each category of AVPU were 1.1% (Alert), 4.3% (Verbal), 17.9% (Pain), 53.2% (Unresponsive); and, for each GCS-based injury severity category, they were 0.9% (Mild, GCS 13-15), 8.1% (Moderate, GCS 9-12), 43.5% (Severe, GCS ≤ 8). Overall, there was a statistically significant difference in GCS for each category of AVPU (p < 0.001) except between patients responding to verbal commands and those responding to pain (p = 0.18). The discriminative ability of AVPU (AUC 79.7% (95% CI 73.4-86.1)) and GCS (AUC 81.5% (95% CI 74.8-88.2)) for death within 48-h following hospital drop-off were comparable. CONCLUSION: EMT assessments of AVPU and GCS relate to each other, and AVPU predicts mortality at 48 h. Future studies using AVPU to assess the level of consciousness in prehospital trauma protocols may simplify their global application without impacting the overall quality of care.

Integration of metabolites from meta-analysis with transcriptome reveals enhanced SPHK1 in PDAC with a background of pancreatitis.

BACKGROUND: Pathophysiology of transformation of inflammatory lesions in chronic pancreatitis (CP) to pancreatic ductal adenocarcinoma (PDAC) is not clear. METHODS: We conducted a systematic review, meta-analysis of circulating metabolites, integrated this data with transcriptome analysis of human pancreatic tissues and validated using immunohistochemistry. Our aim was to establish biomarker signatures for early malignant transformation in patients with underlying CP and identify therapeutic targets. RESULTS: Analysis of 19 studies revealed AUC of 0.86 (95% CI 0.81-0.91, P < 0.0001) for all the altered metabolites (n = 88). Among them, lipids showed higher differentiating efficacy between PDAC and CP; P-value (< 0.0001). Pathway enrichment analysis identified sphingomyelin metabolism (impact value-0.29, FDR of 0.45) and TCA cycle (impact value-0.18, FDR of 0.06) to be prominent pathways in differentiating PDAC from CP. Mapping circulating metabolites to corresponding genes revealed 517 altered genes. Integration of these genes with transcriptome data of CP and PDAC with a background of CP (PDAC-CP) identified three upregulated genes; PIGC, PPIB, PKM and three downregulated genes; AZGP1, EGLN1, GNMT. Comparison of CP to PDAC-CP and PDAC-CP to PDAC identified upregulation of SPHK1, a known oncogene. CONCLUSIONS: Our analysis suggests plausible role for SPHK1 in development of pancreatic adenocarcinoma in long standing CP patients. SPHK1 could be further explored as diagnostic and potential therapeutic target.

Pre-hospital airway management and survival outcomes after paediatric out-of-hospital cardiac arrests.

BACKGROUND: Paediatric out-of-hospital cardiac arrest (OHCA) results in high mortality and poor neurological outcomes. We conducted this study to describe and compare the effects of pre-hospital airway management on survival outcomes for paediatric OHCA in the Asia-pacific region. METHODS: We performed a retrospective analysis of the Pan Asian Resuscitation Outcomes Study (PAROS) data from January 2009 to June 2018. PAROS is a prospective, observational, multi-centre cohort study from eleven countries. The primary outcomes were one-month survival and survival with favourable neurological status, defined as Cerebral Performance Category1 or 2. We performed multivariate analyses of the unmatched and propensity matched cohort. RESULTS: We included 3131 patients less than 18 years in the study. 2679 (85.6%) children received bag-valve-mask (BVM) ventilations, 81 (2.6%) endotracheal intubations (ETI) and 371 (11.8%) supraglottic airways (SGA). 792 patients underwent propensity score matching. In the matched cohort, advanced airway management (AAM: SGA and ETI) when compared with BVM group was associated with decreased one-month survival [AAM: 28/396 (7.1%) versus BVM: 55/396 (13.9%); adjusted odds ratio (aOR), 0.46 (95% CI, 0.29 - 0.75); p = 0.002] and survival with favourable neurological status [AAM: 8/396 (2.0%) versus BVM: 31/396 (7.8%); aOR, 0.22 (95% CI, 0.10 - 0.50); p < 0.001]. For SGA group, we observed less 1-month survival [SGA: 24/337 (7.1%) versus BVM: 52/337 (15.4%); aOR, 0.41 (95 %CI, 0.25-0.69), p = 0.001] and survival with favourable neurological status. CONCLUSION: In children with OHCA in the Asia-Pacific region, pre-hospital AAM was associated with decreased one-month survival and less favourable neurological status.

A comparative study on psychiatric morbidity among elderly population residing in old-age homes and community.

Aims and Objectives: The objective of this study is to study, assess and compare the socio-demographic profile, psychiatric morbidity, cognitive functioning, quality of life and social support of senior citizens in care homes as well as in the communities. Material and Methods: Hundred subjects (50 were from old-age home and the rest were from the community) were assessed using intake pro forma details and an interview questionnaire. The Geriatric Mental Status questionnaire, Mini-Mental Status Examination, Quality of Life Support, and Multidimensional Scale of Perceived Social Support scales were then performed on each subject from the two groups in that order, and they were rated on all scales. Results: Individuals with lack of spouse and lack of children were higher and common attitude was death in old-age homes. Past history of psychiatric illnesses was more in the inmates of old-age homes. Memory disturbances, concentration problems, hypochondriasis, somatic dysfunction, error behaviour, thought disturbances, perceptual disturbances, persecution, expressed happiness and satisfaction were greater in the inmates of old-age care homes. The quality of life was poor in community group than in old-age home group. Conclusion: There is a need to increase community and health-care professional awareness of mental health problems in later life, as well as improve access to appropriate geriatric and mental healthcare.

The role of 108 GVK EMRI ambulance services in the management of behavioral emergencies in the state of Telangana.

Mental health is a major public health issue that calls for immediate steps by individuals and societies around the globe. Talking about mental health issues has always been considered a taboo, especially in lower-middle income countries. This paper assesses the role of GVK Emergency Management Research Institute (GVK EMRI) 108 Ambulance Services in the management of behavioral emergencies in the state of Telangana, India. Primary data collection was carried out in Devaryamjal village of Medchal District with people from both rural and urban setting. The use of management services for behavioral emergencies are described, and knowledge attitude and practices in communities regarding the use of these services are identified. The impact of the Covid-19 pandemic on the mental health of individuals is considered as well, and recommendations to strengthen 108 services for managing behavioral emergencies are suggested. As GVK EMRI is a first responder organization, understanding its role in the field of behavioral emergencies can fundamentally impact several lives. Findings indicate that mental health problems exist in communities, but individuals are reluctant to seek help. People from the urban setting were more open to talk about the topic. The awareness of 108 as an emergency response service was immaculate and a positive view was held about the services and the organization.

Gender disparities among adult recipients of layperson bystander cardiopulmonary resuscitation by location of cardiac arrest in Pan-Asian communities: A registry-based study.

BACKGROUND: Bystander cardiopulmonary resuscitation (BCPR) is a critical component of the 'chain of survival' in reducing mortality among out-of-hospital cardiac arrest (OHCA) victims. Inconsistent findings on gender disparities among adult recipients of layperson BCPR have been reported in the literature. We aimed to fill this knowledge gap by investigating the extent of gender disparities in a cross-national setting within Pan-Asian communities. METHODS: We utilised data collected from the Pan-Asian Resuscitation Outcomes Study (PAROS), an international, multicentre, prospective study conducted between 2009 and 2018. We included all OHCA cases with non-traumatic arrest aetiology transported by emergency medical services and excluded study sites that did not consistently collect information about the location of cardiac arrest. Logistic regression was used to analyse the association between gender and BCPR, stratified by location. FINDINGS: We analysed a cohort of 56,192 OHCA cases with an overall BCPR rate of 36.2% (20,329/56,192). At public locations, the BCPR rate was 31.2% (631/2022) for female and 36.4% (3235/8892) for male OHCA victims; while at home, the rate was 38.3% (6838/17,842) for females and 35.1% (9625/27,436) for males. Controlling for site differences and several factors in multivariable logistic regression, we found females less likely to receive BCPR than males in public locations (odds ratio [OR]=0.89, 95% confidence interval [CI]: 0.70-0.99), but more likely to receive BCPR at home (OR=1.16, 95% CI: 1.11-1.21). INTERPRETATION: In Pan-Asian communities, gender differences exist in adult recipients of BCPR and differ between home and public locations. Future studies should account for additional information on bystanders and societal factors to identify targets for interventions. FUNDING: The study was supported by grants from the National Medical Research Council (NMRC/CSA/0049/2013) and Laerdal Foundation (20040).

"So Why Should I Call Them?": Survivor Support Service Characteristics as Drivers of Help-Seeking in India.

Women in South Asia face the highest lifetime prevalence of intimate partner violence in the world, which is just one form of violence against women (VAW). In India, few women seek help after experiencing violence, particularly from formal resources, such as physicians or the police. While many studies have investigated the impact of survivor characteristics and patterns of violence on help-seeking behaviors, there is scant research on support service characteristics and their impact on help-seeking. The introduction of a novel crisis helpline in Gujarat, India provided an opportunity to better understand how successful help-seeking can be driven by the perceived and experienced characteristics of the helpline. We conducted in-depth interviews with helpline users to identify factors and pathways that promoted or discouraged help-seeking in general, help-seeking from a formal source, and help-seeking from this particular helpline. We analyzed 32 interviews of women who used the helpline. Participants were from eight districts across the state, representing a diverse range of sociodemographic backgrounds. After conducting a thematic analysis, we found that action-oriented service, timeliness, and women-focused staff influenced (positively and negatively) participants' feelings of safety, empowerment, and trust in the helpline, which ultimately impacted their decision to seek help from the helpline or even to seek help at all. This study illuminates how service characteristics, in and of themselves, can influence the likelihood that survivors will seek help, emphasizing the need for survivors to have a voice in the growth and refinement of VAW support services. Consequently, these areas must be a focus of future research and initiatives to improve help-seeking by VAW survivors.

MUC1, CK20, and CDX2 immunohistochemical markers can sub-classify periampullary carcinomas into pancreaticobiliary, intestinal, and mixed subtypes.

INTRODUCTION: Pancreaticobiliary subtype of Periampullary carcinoma (PAC) has a poor prognosis in comparison to the intestinal subtype. We assessed the potential of cytokeratins and mucin markers to classify the sub-types of periampullary tumors and compared them with the survival data to identify markers that may predict prognosis. METHODOLOGY: PAC tumor tissues were obtained from 94 patients undergoing Whipples Pancreaticoduodenectomy. Paraffin-embedded tissues were immunostained with cytokeratins CK7, CK20), mucins (MUC1, MUC2, MUC5Ac), and CDX2 antibodies. The survival status of patients was obtained as follow-up up to 5-years of surgery. The Receiver Operating Character Curve (ROC) analysis was used for detecting sensitivity and specificity. The survival data were analyzed using the Kaplan-Meier survival curve. RESULTS: Tumors were initially categorized on the basis of histological classification as pancreaticobiliary (n = 46), intestinal (n = 35) and indeterminate (n = 13). Further, using immunohistochemical markers (MUC1, CK20, and CDX2), we gave systematic classification of IHC-PB (n = 51), IHC-Int (n = 30) and IHC-Mixed (n = 13). The interobserver analysis showed good agreement between histologic and IHC type with a kappa value of 0.554. Combined expression of CK20, MUC1 and CDX2 accurately classify the mixed type of tumor. Overall survival rate and duration were 74.4% and 44.95 ± 2.29 months. Survival analysis for subtypes reveal, pancreaticobiliary tumors have low survival (27.9 ± 1.63 months) than mixed type (35.5 ± 0.45 months) and intestinal-type (52.92 ± 2.18 months). Among these, intestinal-type have better survival. Only TNM Stage III (tumor staging as per American Joint Committee on Cancer classification) and perineural invasion have been associated with predicting poor survival in PAC patients. CONCLUSION: Our results suggest that the combined expression of MUC1, CK20 and CDX2 could serve as markers to diagnose histological inconclusive specimens as mixed subtype tumors.

COVID-19 associated mucormycosis: A Descriptive Multisite Study from India.

BACKGROUND AND AIMS: Mucormycosis is an invasive fungal infection and carries a significant morbidity and mortality. A number of cases of mucormycosis have been reported in association with COVID-19. In this study, a consortium of clinicians from various parts of India studied clinical profile of COVID-19 associated mucormycosis (CAM) and this analysis is presented here. METHODS: Investigators from multiple sites in India were involved in this study. Clinical details included the treatment and severity of COVID-19, associated morbidities, as well as the diagnosis, treatment and prognosis of mucormycosis. These data were collected using google spreadsheet at one centre. Descriptive analysis was done. RESULTS: There were 115 patients with CAM. Importantly, all patients had received corticosteroids. Diabetes was present in 85.2% of patients and 13.9% of patients had newly detected diabetes. The most common site of involvement was rhino-orbital. Mortality occurred in 25 (21.7%) patients. On logistic regression analysis, CT scan-based score for severity of lung involvement was associated with mortality. CONCLUSION: Universal administration of corticosteroids in our patients is notable. A large majority of patients had diabetes, while mortality was seen in ∼1/5th of patients, lower as compared to recently published data.

Is intraoperative enteroscopy still relevant in small bowel disorders in the era of capsule endoscopy and device-assisted enteroscopy? Real-world experience from a tertiary care hospital.

BACKGROUND AND AIM: With the advent of video capsule endoscopy (VCE) and device-assisted enteroscopy (DAE), the indication of intraoperative enteroscopy (IOE) has become limited due to reported high morbidity/mortality. Most of the earlier studies on IOE were small/from pre-VCE/DAE era. We aimed to evaluate the impact of IOE in management of small bowel disorders (SBD) in post-VCE/DAE era. METHODS: Patients with SBD undergoing IOE over last 15 years were evaluated retrospectively. Overall diagnostic/therapeutic yield, incremental diagnostic yield over preoperative investigations, and adverse events were noted. We also evaluated the number of cases in which IOE changed the management or guided surgical or endoscopic therapy. Rebleeding and recurrence were evaluated in patients with available follow-up data. RESULTS: A total of 89 patients (59 male, 9-82 years) were included in the study. Overall diagnostic and therapeutic yield were 92.1% and 85.4%, respectively. Common findings of IOE were benign ulcers/strictures (30.1%), vascular lesions (26%), diverticula (15.1%), and tumors (13.7%). A total of 49.4% (44/89), 36% (32/89), and 20.2% (18/89) underwent VCE, DAE, or both, respectively, before IOE. Incremental diagnostic yield over preoperative work-up was 31.5% (28/89), and IOE changed the management in 37.1% (33/89) patients. IOE was used to guide surgery/endotherapy in 39.3% (35/89) patients. Recurrent gastrointestinal bleed occurred in 21.2% (14/66) patients. Morbidity and mortality rates were 20.2% (18/89) and 3.4% (3/89), respectively. CONCLUSIONS: Intraoperative enteroscopy remains an essential technique to evaluate SBD and can detect new and additional lesions even after extensive preoperative evaluation. IOE is useful in guiding therapy in preoperatively identified lesions and can change management in a substantial proportion of patients. Hence, IOE has a definitive role in post-VCE/DAE era in carefully selected patients with SBD.
