First Measurement of the |t| Dependence of Incoherent J/ψ Photonuclear Production. PHYSICAL REVIEW LETTERS 2024; 132:162302. [PMID: 38701458 DOI: 10.1103/physrevlett.132.162302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 11/22/2023] [Accepted: 01/23/2024] [Indexed: 05/05/2024]
Abstract
The first measurement of the cross section for incoherent photonuclear production of J/ψ vector mesons as a function of the Mandelstam |t| variable is presented. The measurement was carried out with the ALICE detector at midrapidity, |y|<0.8, using ultraperipheral collisions of Pb nuclei at a center-of-mass energy per nucleon pair of sqrt[s_{NN}]=5.02 TeV. This rapidity interval corresponds to a Bjorken-x range (0.3-1.4)×10^{-3}. Cross sections are given in five |t| intervals in the range 0.04<|t|<1 GeV^{2} and compared to the predictions by different models. Models that ignore quantum fluctuations of the gluon density in the colliding hadron predict a |t| dependence of the cross section much steeper than in data. The inclusion of such fluctuations in the same models provides a better description of the data.

Abstract
Brucellosis is a neglected zoonosis that affects animals and people in much of the underdeveloped world. The disease is endemic in cattle in Punjab, India and controlling it is a public health challenge. Dairy farmers and farm labour commonly handle cattle faeces with bare hands and personal protective equipments are not used. No studies have been conducted about the shedding of Brucella species in faeces of sero positive cattle in the state. This study aimed to isolate and identify the Brucella species from faeces of sero positive cattle in Punjab, India. Faecal samples were collected from 350 Brucella sero positive cattle in Ludhiana district of Punjab, India. Isolation was performed using a pre-enriched Brucella selective broth medium as well as Brucella selective medium agar plates containing horse serum and Brucella selective supplements. Isolates were identified using Gram staining technique and rapid slide agglutination test, and then confirmed by using bcsp31 and 16s rRNA genus specific PCR. Isolates were further identified up to species level by using Bruce-Ladder multiplex PCR. Fourteen Brucella species were isolated, all of which showed coccobacilli on gram staining, positive rapid slide agglutination test and amplification of bcsp31 and 16s rRNA genes. Of the 14 isolates, 11 were identified as Brucella abortus and 3 were identified as Brucella melitensis. The study demonstrates that animal faeces could pose a potential risk for animal and human health and faeces of seropositive cattle must be handled with care.

Formal mentorship in Canadian radiology residency programmes. Clin Radiol 2023; 78:e676-e680. [PMID: 37336675 DOI: 10.1016/j.crad.2023.05.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 05/13/2023] [Accepted: 05/16/2023] [Indexed: 06/21/2023]
Abstract
AIM To characterise formal mentorship programmes in Canadian radiology residency programmes, to evaluate residents' perspectives on formal mentorship, and to identify ways to optimise mentorship during radiology training. MATERIALS AND METHODS An anonymous survey was distributed to radiology resident representatives of the Canadian Association of Radiologists (CAR) Resident and Fellow Section (RFS). Questions pertained to the presence and structure of formal mentorship programmes at each participant's institution. RESULTS The survey was distributed to 33 radiology residents, of which 30 responded. All 16 accredited radiology residency programmes in Canada were represented. Of these programmes, 12 (75%) had formal mentorship programmes and four (25%) did not. The structure of formal mentorship programmes varied among institutions including one-on-one and group mentoring. For 33% of residency programmes, the programme director assigned the mentor and mentee groups. Only 33% of respondents had the option of choosing their mentor. Lack of funding and lack of time were the two main perceived barriers by residents to maintaining mentorship relationships. CONCLUSION Although not all radiology residency programmes in Canada have a formal mentorship programme, most have a form of structured mentorship in place. As formal mentorship programmes improve overall mentorship experience during residency, they can lead to improved research productivity, fellowship, and career preparation, as well as work-life balance for Canadian radiology residents.

The influence of anastomotic techniques on postoperative anastomotic complications: Results of the Oesophago-Gastric Anastomosis Audit. J Thorac Cardiovasc Surg 2022; 164:674-684.e5.

Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Stable and Discriminatory Radiomic Features from the Tumor and Its Habitat Associated with Progression-Free Survival in Glioblastoma: A Multi-Institutional Study. AJNR Am J Neuroradiol 2022; 43:1115-1123.

Abstract
BACKGROUND AND PURPOSE Glioblastoma is an aggressive brain tumor, with no validated prognostic biomarkers for survival before surgical resection. Although recent approaches have demonstrated the prognostic ability of tumor habitat (constituting necrotic core, enhancing lesion, T2/FLAIR hyperintensity subcompartments) derived radiomic features for glioblastoma survival on treatment-naive MR imaging scans, radiomic features are known to be sensitive to MR imaging acquisitions across sites and scanners. In this study, we sought to identify the radiomic features that are both stable across sites and discriminatory of poor and improved progression-free survival in glioblastoma tumors. MATERIALS AND METHODS We used 150 treatment-naive glioblastoma MR imaging scans (Gadolinium-T1w, T2w, FLAIR) obtained from 5 sites. For every tumor subcompartment (enhancing tumor, peritumoral FLAIR-hyperintensities, necrosis), a total of 316 three-dimensional radiomic features were extracted. The training cohort constituted studies from 4 sites (n = 93) to select the most stable and discriminatory radiomic features for every tumor subcompartment. These features were used on a hold-out cohort (n = 57) to evaluate their ability to discriminate patients with poor survival from those with improved survival. RESULTS Incorporating the most stable and discriminatory features within a linear discriminant analysis classifier yielded areas under the curve of 0.71, 0.73, and 0.76 on the test set for distinguishing poor and improved survival compared with discriminatory features alone (areas under the curve of 0.65, 0.54, 0.62) from the necrotic core, enhancing tumor, and peritumoral T2/FLAIR hyperintensity, respectively. CONCLUSIONS Incorporating stable and discriminatory radiomic features extracted from tumors and associated habitats across multisite MR imaging sequences may yield robust prognostic classifiers of patient survival in glioblastoma tumors.

Abstract
Paragangliomas of the trachea are rare neoplasms and can present to the clinician with acute airway problems. These neoplasms sometimes are misdiagnosed by general practitioners as asthmatic exacerbation. We present the case of a 66-year-old woman who presented to us with a history of dyspnoea at rest in the supine position and on exertion and a productive cough. This was diagnosed as bronchial asthma and she was treated with corticosteroid inhalers for four months by her GP. She was subsequently evaluated by computed tomography of the neck and thorax, which revealed an intratracheal enhancing lesion measuring around 11 mm in the lower cervical trachea. Fibreoptic bronchoscopy showed a mass lesion at the level of mid trachea. A low tracheostomy was followed by telescopic examination and the mass was resected using coablation. Histology of the mass was reported as paraganglioma. Difficulties encountered and literature review of various management options are presented in this report.

Abstract
Budd-Chiari syndrome (BCS) is a rare disease characterized by hepatic venous outflow tract obstruction, frequently due to an underlying thrombophilic disorder. Acute myeloid leukemia rarely presents as acute BCS due to hyperfibrinolysis, hyperleukocytosis, nonspecific proteolytic activity, and disseminated intravascular coagulation causing acute hepatic vein thrombosis. In patients presenting with acute BCS with acute liver failure (ALF), a high index of suspicion and exclusion of underlying malignancy is a must, as it is a contraindication for liver transplantation. We report a case of a 19-year-old Caucasian male who presented with acute BCS causing ALF as an initial presentation of acute myelogenous leukemia.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
UNLABELLED Encephalitis is challenging to manage given the diversity of clinical and epidemiologic features. Various predictors of outcome have been studied so far including thrombocytopenia, cerebral edema, hypoglycaemia, development of status epilepticus and need for endotracheal intubation. Thrombocytopenia represents one of the potentially modifiable risk factors for poor prognosis in encephalitis. A better understanding of the epidemiology of this devastating disease and identification of predictors of outcome and management of reversible factors will pave the way for better management of the disease. MATERIAL A total of 98 Hospitalised patients of Acute Encephalitis were enrolled in the study. Diagnoses were confirmed by CSF and Neuroimaging studies. Platelet count <150,000/cumm was considered as thrombocytopenia. Mild, moderate and severe thrombocytopenia was categorized at platelet count 100,000-150,000, 50,000-100,000 and <50,000/ cumm, respectively. Outcome at discharge was assessed using the Modified Ranking Score, categorized into 3 groups - good (0-2), fair (3-4), and poor (5-6). Chi-square, ANOVA and Independent samples 't'-tests were used to compare the data. OBSERVATION Mean age of patients was 34.06±18.76 (range 14-85) years. Majority of patients were males (54.1). Mean GCS at admission was 9.41±1.90. Acute viral encephalitis(unclassified) (n=33; 33.7%), Scrub typhus (n=24; 24.5%) and Japanese encephalitis virus (n=12; 12.2%) were the most common underlying etiologies. A total of 74 (75.5%) patients had thrombocytopenia. Mild, moderate and severe thrombocytopenia was seen in 34 (34.7%), 30 (30.6%) and 10 (10.2%) cases. Thrombocytopenia was significantly higher in Dengue and Scrub as compared to other etiologies. Thrombocytopenia and its severity showed a significant association with lower GCS and higher mRS scores indicating a poor outcome. CONCLUSION Thrombocytopenia is associated with a poor clinical status and adverse outcomes in patients with encephalitis of all causes.

Postoperative outcomes in oesophagectomy with trainee involvement. BJS Open 2021; 5:zrab132. [PMID: 35038327 PMCID: PMC8763367 DOI: 10.1093/bjsopen/zrab132] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 11/15/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Paving the way for application of next generation risk assessment to safety decision-making for cosmetic ingredients. Regul Toxicol Pharmacol 2021; 125:105026.

Abstract
Next generation risk assessment (NGRA) is an exposure-led, hypothesis-driven approach that has the potential to support animal-free safety decision-making. However, significant effort is needed to develop and test the in vitro and in silico (computational) approaches that underpin NGRA to enable confident application in a regulatory context. A workshop was held in Montreal in 2019 to discuss where effort needs to be focussed and to agree on the steps needed to ensure safety decisions made on cosmetic ingredients are robust and protective. Workshop participants explored whether NGRA for cosmetic ingredients can be protective of human health, and reviewed examples of NGRA for cosmetic ingredients. From the limited examples available, it is clear that NGRA is still in its infancy, and further case studies are needed to determine whether safety decisions are sufficiently protective and not overly conservative. Seven areas were identified to help progress application of NGRA, including further investments in case studies that elaborate on scenarios frequently encountered by industry and regulators, including those where a ‘high risk’ conclusion would be expected. These will provide confidence that the tools and approaches can reliably discern differing levels of risk. Furthermore, frameworks to guide performance and reporting should be developed.

Mortality from esophagectomy for esophageal cancer across low, middle, and high-income countries: An international cohort study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2021; 47:1481-1488. [PMID: 33451919 DOI: 10.1016/j.ejso.2020.12.006] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Accepted: 12/09/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract
BACKGROUND The Esophagectomy Complications Consensus Group (ECCG) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA) have set standards in reporting outcomes after oesophagectomy. Reporting outcomes from selected high-volume centres or centralized national cancer programmes may not, however, be reflective of the true global prevalence of complications. This study aimed to compare complication rates after oesophagectomy from these existing sources with those of an unselected international cohort from the Oesophago-Gastric Anastomosis Audit (OGAA). METHODS The OGAA was a prospective multicentre cohort study coordinated by the West Midlands Research Collaborative, and included patients undergoing oesophagectomy for oesophageal cancer between April and December 2018, with 90 days of follow-up. RESULTS The OGAA study included 2247 oesophagectomies across 137 hospitals in 41 countries. Comparisons with the ECCG and DUCA found differences in baseline demographics between the three cohorts, including age, ASA grade, and rates of chronic pulmonary disease. The OGAA had the lowest rates of neoadjuvant treatment (OGAA 75.1 per cent, ECCG 78.9 per cent, DUCA 93.5 per cent; P < 0.001). DUCA exhibited the highest rates of minimally invasive surgery (OGAA 57.2 per cent, ECCG 47.9 per cent, DUCA 85.8 per cent; P < 0.001). Overall complication rates were similar in the three cohorts (OGAA 63.6 per cent, ECCG 59.0 per cent, DUCA 62.2 per cent), with no statistically significant difference in Clavien-Dindo grades (P = 0.752). However, a significant difference in 30-day mortality was observed, with DUCA reporting the lowest rate (OGAA 3.2 per cent, ECCG 2.4 per cent, DUCA 1.7 per cent; P = 0.013). CONCLUSION Despite differences in rates of co-morbidities, oncological treatment strategies, and access to minimal-access surgery, overall complication rates were similar in the three cohorts.

Abstract
Background This study focuses on experience of laparoscopic surgery at Shahid Dharma Bhakta National Transplant Centre (SDNTC), Nepal; which could enable us to gain knowledge regarding its benefits over conventional surgery. The present study revealed the frequency of various forms of laparoscopic surgeries done at our centre. Moreover, this study accomplishes laparoscopic donor nephrectomy "a historical milestone achieved in Nepal for kidney transplantation on 18th November 2018" which was the first Laparoscopic donor nephrectomy done in Nepal by Nepalese team. Objective The present study assesses the feasibility and safety of laparoscopic surgery at government hospital of Nepal. Method This hospital based cross-sectional study included all patients of age group 10 to 60 years, coming to outpatient department of SDNTC and those having indications for nephrectomy. We excluded patient having previous history of open surgeries of kidney, bleeding disorders, uncontrolled Diabetes Mellitus and uncontrolled Hypertension. The study duration was 15 months from November 2017 to January 2019. The total number of patients enrolled in the study was fifty where transperitoneal laparoscopic surgery was performed in all 50 patients. The demographic data, indications for surgery, duration of surgery, complications of surgery and perioperative outcomes were analyzed. Result Out of 50 cases, 34 (68%) underwent simple lap nephrectomy, 6 (12%) were lap pyeloplasty, 6 (12%) lap nephrectomy along with ureterectomy of long segment of diseased ureter, 1 (2%) lap radical nephrectomy, 1 (2%) lap donor nephrectomy for kidney transplantation, 1 (2%) lap heminephrectomy and 1 (2%) lap nephrectomy for hydronephrotic non functioning left crossed ectopia. Amongst all nephrectomies, 27 (54%) patients were operated on right side while 23 (46%) patients on left. The median age of the patient was 38.56 years. Out of total cases 32 (64%) were male and 18 (36%) female. The median operative time and hospital stay was 122.3 minutes and 5 days respectively. The median estimated blood loss was 74.1 cc. Only one patient required blood transfusion intra-operatively. 2 (4%) patients were converted to open surgery. Conclusion Laparoscopic surgery is feasible and safe procedure in government setup hospital with less cumbersome procedure and minimum complications associated with it.

Abstract
INTRODUCTION Nonalcoholic fatty liver disease (NAFLD) has been increasingly reported among recipients of liver transplantation (LT). We aimed to identify clinical and genetic risk factors responsible for the development of early recurrent NAFLD in nonalcoholic steatohepatitis transplant recipients. METHODS Forty-six total single nucleotide polymorphisms with known association with NAFLD were tested among both recipient and donor liver samples in 66 LT recipients with nonalcoholic steatohepatitis to characterize influences on NAFLD recurrence at ∼1 year post-LT (median interval from LT to biopsy: 377 days). RESULTS Recurrent NAFLD was identified in 43 (65.2%) patients, 20 (30.3%) with mild recurrence, and 23 (34.8%) with moderate to severe NAFLD. On adjusted analysis, change in the body mass index (BMI) (ΔBMI) was significantly associated with NAFLD recurrence, whereas post-LT diabetes mellitus was associated with increased severity of NAFLD recurrence. ADIPOR1 rs10920533 in the recipient was associated with increased risk of moderate to severe NAFLD recurrence, whereas the minor allele of SOD2 rs4880 in the recipient was associated with reduced risk. Similar reduced risk was noted in the presence of donor SOD2 rs4880 and HSD17B13 rs6834314 polymorphism. DISCUSSION Increased BMI post-LT is strongly associated with NAFLD recurrence, whereas post-LT diabetes mellitus was associated with increased severity of NAFLD recurrence. Both donor and recipient SOD2 rs4880 and donor HSD17B13 rs6834314 single nucleotide polymorphisms may be associated with reduced risk of early NAFLD recurrence, whereas presence of the minor allele form of ADIPOR1 rs10920533 in the recipient is associated with increased severity NAFLD recurrence.

Abstract
Background Spontaneous bacterial peritonitis (SBP) is a serious complication of cirrhosis and is associated with high morbidity and mortality. Rapid institution of appropriate antibiotics is central to the improved patient outcome. Correctly obtaining ascites fluid for analysis has several technical and logistic limitations resulting in overuse of empiric antibiotics when patients are admitted to the hospital with suspected SBP. Procalcitonin and C-reactive protein (CRP) are non-invasive markers of infection. We conducted a study to illustrate the role of these markers in making the diagnosis of SBP in patients with cirrhosis. Methods A total of 45 patients were enrolled in this prospective cohort study, 14 (31.1%) of which were found to have SBP. Ascitic fluid neutrophils, serum procalcitonin and CRP levels were measured prior to initiation of antibiotics and these parameters were compared between the two groups. Area under receiver operator characteristic (AUROC) curves were used to assess the diagnostic accuracy of procalcitonin and CRP in this population. We defined neutrocytic SBP group as a combination of patients who had classic SBP (positive ascitic culture and >250 neutrophils/mm3) and culture-negative neutrocytic ascites. Results Serum procalcitonin (2.81±2.59 vs. 0.43±0.48 ng/mL; P=0.0032), serum CRP (60.30±44.48 vs. 22.2±23.28; P=0.0055) and ascitic fluid neutrophil levels (49.23±30.90 vs. 16.7±20.39; P=0.0064) were significantly higher in SBP group than non-SBP group. AUROC for procalcitonin (cut-off >2.0 ng/mL) was 0.75 (95% CI, 0.61–0.88), CRP (cut-off >3.0 mg/L) was 0.55 (95% CI, 0.43–0.68) and for procalcitonin combined with CRP was 0.76 (95% CI, 0.61–0.90) for diagnosing all-cause SBP. In a subgroup analysis of patients with neutrocytic SBP, AUROC for procalcitonin was 0.88 (95% CI, 0.74–1.00), CRP was 0.62 (95% CI, 0.45–0.79) and for procalcitonin combined with CRP was 0.93 (95% CI, 0.81–1.00). Addition of CRP to procalcitonin did not significantly change the AUROC for diagnosis of SBP. Conclusions Serum procalcitonin could be used as an adjunctive non-invasive biomarker in diagnosing SBP with a high degree of accuracy in cirrhotic patients. Addition of CRP does not seem to significantly increase the diagnostic accuracy of procalcitonin.

Abstract
Hilar cholangiocarcinoma, also known as Klatskin tumor, is the most common type of cholangiocarcinoma. It usually has a lymphatic spread and is rarely associated with an umbilical nodule, also known as Sister Mary Joseph nodule. We report a case of a 53-year-old Caucasian man with hilar cholangiocarcinoma. The patient had an inoperable tumor and was referred to our center for liver transplantation. Post liver transplantation, the patient presented with a recurrence of the carcinoma in the umbilical region. The patient was found to have Sister Mary Joseph nodule. It carries a poor prognosis, and our patient succumbed to the illness in four months. Cholangiocarcinoma carries a poor prognosis. Surgical resection and liver transplantation with neoadjuvant chemoradiation are the preferred treatment strategies. Association of cholangiocarcinoma with umbilical metastasis is rare, and our patient had an even rarer presentation in the form of recurrence with umbilical nodule post-liver transplantation. We want to increase the awareness of the rare presentation, association, and recurrence of hilar cholangiocarcinoma in the form of umbilical nodule post-liver transplantation.

Abstract
High-performance polymer matrix nanocomposites based on poly(ether-sulfone) (PES) matrix reinforced with multi-walled carbon nanotubes (MWCNTs) were fabricated using planetary ball mill followed by hot pressing. Their electrical properties and the electromagnetic interference shielding effectiveness (EMI-SE) were investigated and discussed. A percolation threshold of about 0.65 vol% MWCNT was obtained. The electrical conductivity was increased by more than ten orders of magnitude at the percolation threshold and to approximately 0.01 S cm-1 at 6.67 vol% (or 10 wt%) MWCNT. This is a significant improvement. The highest EMI-SE of about 29-30 dB (both in the X-band and Ku-band) was obtained for the 6.67 vol% MWCNT filled nanocomposites with a thickness of 0.9 mm. The specific EMI-SE of these nanocomposites were found to be higher than the literature values. The thermal stability and the char yield (measured at 900 °C) of the nanocomposites were found to be more than 470 °C and 40.6%, respectively.

Abstract
Granulomatous myositis is a rare disease that predominantly results in proximal muscle weakness in the upper and/or lower extremities. As it can resemble other inflammatory myopathies, it is important to obtain a muscle biopsy to make the underlying diagnosis. We report the first case of granulomatous myositis associated with extremely elevated anti-striated muscle antibodies in a 69-year-old Caucasian woman. Granulomatous myositis has been associated with various autoimmune, infectious, rheumatologic, vasculitis, and oncologic disorders, and several antibodies have previously been reported to be associated with it. However, to the best of our knowledge, this is the first report where extremely elevated anti-striated muscle antibodies were found to be associated with granulomatous myositis in the absence of myasthenia gravis. The treatment of granulomatous myositis revolves around the use of corticosteroids, steroid-sparing immunosuppressive agents, and newer biologics.

Abstract
BACKGROUND Guillain-Barré syndrome (GBS) is a monophasic disease characterized by acute polyradiculoneuropathy. AIM This study investigated cardiovascular complications in patients with GBS and their relationship with outcomes. DESIGN AND METHODS We included 96 patients, who were diagnosed with GBS according to Brighton case definitions. All enrolled patients were evaluated according to a predetermined algorithm, which included nerve conduction studies, cerebrospinal fluid analysis, electrocardiography, 2D echo, cardiac markers and autonomic function testing. RESULTS We enrolled a total of 96 patients. The mean age of patients was 35.75 ± 17.66 years. Furthermore, 54.2% of patients developed cardiovascular complications, of which changes in electrocardiography (ECG) findings (50%), hypertension (28.12%), labile hypertension (12.5), tachycardia (26.04), bradycardia (13.54%) and a fluctuating heart rate (HR) (11.46) were common. Other cardiovascular complications seen in GBS patients were increased pro-BNP (26.04%), raised troponin T levels (3.12%), acute coronary syndrome (2.08%), heart failure (2.08%) and abnormal 2D echo findings (8.33%). The results of the univariate analysis revealed that a history of preceding infection, a Medical Research Council sum score, neck muscle weakness, facial nerve involvement, bulbar involvement, respiratory failure, cardiovascular complications, autonomic dysfunction, acute motor sensory axonal neuropathy subtype and baseline Hughes score were significantly (P < 0.005) associated with poor outcomes. However, none of these factors were found to be independently associated with poor outcomes in the multivariate analysis. CONCLUSION A considerable number of patients with GBS developed cardiovascular complications and it needs attention.

Abstract
Intrahepatic cholangiocarcinomas or bile duct cancers comprise approximately 10-20% of all cholangiocarcinomas and may present with right upper quadrant pain, weight loss, liver enzyme abnormalities or they may be completely asymptomatic and be picked incidentally on routine abdominal imaging. Typically, hepatocellular carcinomas have been associated with various paraneoplastic syndromes such as hypercalcemia, erythrocytosis, hypoglycemia, diarrhea and skin changes though paraneoplastic syndromes in the setting of cholangiocarcinoma do occur as well. Cholangiocarcinomas are usually associated with dermal paraneoplastic syndromes (Sweet syndrome, porphyria cutanea tarda, acanthosis nigricans, necrotic migratory erythema, erythema multiforme, bullous pemphigoid), hypercalcemia, leukocytosis and limbic encephalitis. We present a case of an 80-year-old man with intrahepatic cholangiocarcinoma associated with high procalcitonin levels in the absence of infection, paraneoplastic syndromes of hypercalcemia, polycythemia and leukocytosis in the same individual. This constellation of symptoms, to the best of our knowledge, has not been previously reported in the scientific literature.

Abstract
Serotonin syndrome is a clinical diagnosis characterized by a constellation of autonomic and neurological physical examination findings due to the use of one or more serotonergic agents. Due to high morbidity and mortality associated with this condition, high index of suspicion is required in making this diagnosis. Treatment is aimed at discontinuation of the offending agent and supportive care. We present a case of a 28-year-old woman who presented with acetaminophen toxicity, however developed iatrogenic serotonin syndrome due to use of scheduled intravenous metoclopramide. Metoclopramide, by itself, very rarely causes serotonin syndrome and typically results in this condition when used in combination with other pro-serotonergic agents.
