Single-Incision Laparoscopic Cholecystectomy Using the Marionette Transumbilical Approach Is Safe and Efficient with Careful Patient Selection: A Comparative Analysis with Conventional Multiport Laparoscopic Cholecystectomy.

Objectives The "marionette technique" for transumbilical laparoscopic cholecystectomy (m-TLC) offers improved cosmesis and possibly shorter postoperative recovery for patient undergoing laparoscopic cholecystectomy versus the four-port conventional laparoscopic cholecystectomy (CLC). We compared the outcomes of m-TLC and CLC at a tertiary care facility in New York. Methods A retrospective chart review was conducted and data on patients who underwent m-TLC and CLC were retrieved. Hospital length of stay (LOS), operative time, and complications were compared between the two groups using linear and logistic regression, as appropriate. Results M-TLC group patients were significantly younger, predominantly females with lower body mass index. They were less likely to have previous abdominal surgery and more likely to have noninflammatory pathology ( p < 0.05 for all). Nonadjusted LOS (1 vs. 3 days, p -value < 0.0001) and operative time (50 vs. 56 minutes, p -value = 0.007) were significantly lower among patients who underwent m-TLC; however, there was no significant difference on multivariate analysis. In multivariate analysis, there was no difference in the overall complication rate (odds ratio: 1.63; 95% confidence interval 0.02-2.39). Conclusion With careful patient selection, m-TLC offers better cosmesis with comparable safety outcomes. Level of evidence Level III.

Prostatic adenocarcinoma in a patient with persistent Müllerian duct syndrome.

The embryonal male sexual differentiation is driven by testosterone, and Anti-Müllerian hormone (AMH). AMH is responsible for regression of Müllerian ducts in a genetically male fetus. Mutations inactivating AMH or its receptors are responsible for persistent Müllerian duct syndrome (PMDS) in virilized 46, XY males. PMDS is a rare genetic disorder affecting males, with less than 300 cases described in literature. The syndrome is usually recognized early in life with patients present with bilateral undescended testicles, and often decreased testosterone production by Leydig cells later in life. The role of testosterone in the development and progression of prostate cancer is well established, and men with low circulating free testosterone are expected to have a lower risk of developing prostate cancer. Indeed, 2 cases of prostate cancer in patients with PMDS have previously been described. Herein, we are reporting the third of prostate cancer in patient with PMDS.

Warfarin Use Is Associated with Increased Mortality at One Year in Patients with Idiopathic Pulmonary Fibrosis.

OBJECTIVES: We studied the safety and efficacy of warfarin compared to direct acting oral anticoagulant use in patients with IPF. METHODS: We conducted a retrospective cohort study of all patients with IPF who were prescribed warfarin or direct acting oral anticoagulants (DOACs) for cardiac or thromboembolic indications and followed at our institute for their care. Univariate tests and multivariable logistic regression analyses were used for assessing association of variables with outcomes. RESULTS: A total of 73 patients were included in the study with 28 and 45 patients in the warfarin and DOAC groups, respectively. Univariable analysis revealed a significant difference in mortality in one year between warfarin and DOAC groups (7/28 vs. 3/45, p value 0.027). Significantly more patients in the warfarin group suffered an exacerbation that required hospitalization within one year (9/28 vs. 5/45, p value 0.026). Multivariate logistic regression analysis showed that anticoagulation with warfarin was independently associated with mortality at one-year follow-up (OR: 77.4, 95% CI: 5.94-409.3, p value: 0.007). CONCLUSION: In our study of patients with IPF requiring anticoagulants, we noted statistically significant higher mortality with warfarin anticoagulation when compared to DOAC use. Further larger prospective studies are needed to confirm these findings.

Outcomes of SARS-CoV-2 infection in patients with cystic fibrosis: A multicenter retrospective research network study.

BACKGROUND: In this study, we report clinical outcomes in COVID-19 infection in a large cohort of people with cystic fibrosis (pwCF) and compare these outcomes to a propensity score matched cohort of people without CF. METHODS: Analysis of a multicenter research network TriNETX was performed including patients more than 16 years of age diagnosed with COVID-19. Outcomes in COVID-19 positive pwCF were compared with a propensity-matched cohort of people without CF. RESULTS: A total of 507,810 patients with COVID-19 were included (422 patients, 0.08% with CF; 507,388 patients, 99.92% without CF. Mean age at COVID-19 diagnosis in CF cohort was 46.6 ± 19.3 years, with female predominance (n = 225, 53.32%). Majority of the participants were Caucasian (n = 309, 73.22%). In the crude, unmatched analysis, mortality, hospitalization, critical care need, mechanical ventilation, acute kidney injury and composite (combination of intubation and mortality) outcome at 30 days was higher in the pwCF. Following robust propensity matching, pwCF had higher hospitalization rate (RR 1.56, 95% CI 1.20-2.04), critical care need (RR 1.78, 95% CI 1.13-2.79), and acute renal injury (RR 1.60, 95% CI 1.07-2.39) as compared to patients without CF. CONCLUSION: People with CF are at risk of poor outcomes with COVID-19.5.2% of these patients died within one month of COVID-19 diagnosis, and more than one in 10 patients required critical care. Therefore, the relatively young median age of cystic fibrosis patients, and lower prevalence of obesity do not protect these patients from severe disease contrary to prior reports.

Patients with idiopathic pulmonary fibrosis have poor clinical outcomes with COVID-19 disease: a propensity matched multicentre research network analysis.

INTRODUCTION: Outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with pre-existing idiopathic pulmonary fibrosis (IPF) remain understudied, and it is unknown if IPF is an independent predictor of worse disease course. Herein, we report the clinical outcomes in a large cohort of 251 patients with COVID-19 in the setting of known IPF. Outcomes were compared with a propensity matched cohort of patients with COVID-19 without IPF. METHODS: Analysis of a federated multicentre research network TriNetX was performed including patients more than 16 years of age diagnosed with SARS-CoV-2 infection. Outcomes in patients diagnosed as positive for SARS-CoV-2 infection with concurrent IPF were compared with a propensity matched cohort of patients without IPF. RESULTS: A total of 311 060 patients with SARS-CoV-2 infection on the research network were identified, 251 patients (0.08%) carried a diagnosis of IPF. Mean age of patients with IPF was 68.30±12.20 years, with male predominance (n=143, 56.97%). Comorbidities including chronic lower respiratory diseases, diabetes mellitus, ischaemic heart disease and chronic kidney disease were more common in patients with IPF when compared with the non-IPF cohort. After propensity matching, higher rates of composite primary outcome (death or mechanical ventilation) at 30 and 60 days, as well as need for hospitalisation, critical care, and acute kidney injury were observed in the IPF cohort. CONCLUSION: Poor outcomes of COVID-19 disease were observed in patients with IPF after robust matching of confounders. Our data confirm that patients with IPF constitute a high-risk cohort for poor outcomes related to COVID-19 disease.

Outcomes of SARS-CoV-2 infection in patients with pulmonary sarcoidosis: A multicenter retrospective research network study.

BACKGROUND: Analyses of COVID-19 infection outcomes in patients with preexisting pulmonary sarcoidosis are lacking and are limited to case reports or small case series with the largest study reporting outcomes of 37 patients. RESEARCH QUESTION: Retrospective cohort study to assess clinical outcomes of 945 patients with pulmonary sarcoidosis, presenting with COVID 19, compared to a propensity matched cohort of patients without sarcoidosis. STUDY DESIGN AND METHODS: Analysis of a multi-center research network TriNETX was performed including patients more than 16 years of age diagnosed with COVID-19. Outcomes in COVID-19 positive patients with concurrent pulmonary sarcoidosis were compared with a propensity score matched cohort of patients without pulmonary sarcoidosis. RESULTS: A total of 278,271 patients with COVID-19 on the research network were identified, 954 patients (0.34 %) carried a diagnosis of pulmonary sarcoidosis. Mean age of patients with sarcoidosis was 56.3 ± 13.2 years, with female predominance (n = 619, 64.89 %). 49.69 % of the participants were African American (n = 474). Co-morbidities including hypertension, chronic lower respiratory diseases, diabetes mellitus, ischemic heart disease, nicotine dependence, and chronic kidney disease were more common in patients with pulmonary sarcoidosis when compared to the non-pulmonary sarcoidosis cohort (all p values < 0.01). In unmatched analysis, pulmonary sarcoidosis group had higher mortality, increased risk for hospitalization, intubation and need for renal replacement therapy. After propensity score matching, no difference in any of the outcome measures was observed. INTERPRETATION: Crude COVID-19 mortality and other clinical outcome measures are poor in pulmonary sarcoidosis cohort; however, propensity-matched analyses revealed no difference in outcomes, showing that higher mortality is driven by higher burden of comorbidities.

Outcomes of COVID-19 in Solid Organ Transplant Recipients: A Propensity-matched Analysis of a Large Research Network.

BACKGROUND: Organ transplant recipients comprise an immunocompromised and vulnerable cohort. Outcomes of coronavirus disease 2019 (COVID-19) in solid organ transplant (SOT) recipients remain understudied. METHODS: We used a multicenter federated research network to compare clinical outcomes of COVID-19 in patients with SOT to a propensity--matched cohort of patients without SOT. RESULTS: We identified 2307 SOT recipients and 231 047 nontransplant patients with COVID-19. Transplant patients were more likely to be male individuals, older, have a body mass index >30 kg/m2, and have comorbid hypertension, diabetes, nicotine dependence, heart failure, and ischemic heart disease compared with the nontransplant group (P < 0.05). One-to-one matching was performed for diabetes, hypertension, chronic lung diseases, race, nicotine dependence, heart failure, ischemic heart disease, and gender. There was no difference in the composite outcome of intubation or mechanical ventilation at 30 days (risk ratio [RR], 1.04; 95% confidence interval [CI], 0.86-1.26) or 60 days (RR, 1.03; 95% CI, 0.86-1.24) between the 2 groups. Hospitalization rate was higher in the transplant cohort (30.97% versus 25.47%; RR, 1.22; 95% CI, 1.11-1.34). There was no difference in mortality at 30 days (6.45% versus 5.29%; RR, 1.22; 95% CI, 0.88-1.68) or 60 days postdiagnosis (RR, 1.05; 95% CI, 0.83-1.32). More patients in the SOT group developed acute renal injury compared with non-SOT cohort (24.73% versus 14.29%; RR, 1.73; 95% CI, 1.53-1.96). CONCLUSIONS: Patients with SOT have high COVID-19-related mortality; however, propensity-matched analyses reveal that this increased risk is secondary to higher burden of comorbidities. SOT status independently increases risk of hospital admission and acute kidney injury.

Are We Overradiating Patients with Irritable Bowel Syndrome?

INTRODUCTION: Protracted exposures to small doses of radiation, even cumulative effective doses (CED) as low as 50-100 mSv, may increase the risk for malignancy. Medical radiation exposure has not been rigorously examined for patients with irritable bowel syndrome (IBS). We examined medical radiation exposure in patients with IBS at a tertiary care center in the USA. METHODS: Patients diagnosed with IBS at our institute from 2009 to 2018 were included in a retrospective cohort study. Medical charts were examined to calculate total and annual CED. RESULTS: 221 patients were included; mean CED was 40.32 mSv (SD: 54.36). Fifty-nine participants (26.7%) received >50 mSv of CED with 27 participants (12.2%) exceeding 100 mSv. Conventional imaging, nuclear medicine, and fluoroscopy accounted for 74.08, 12.93, and 12.98% of total CED, respectively. CT scans contributed to 66.61% of total CED. Outpatient orders accounted for 37.96% of total CED, while 31.4% of total CED was ordered in the emergency department. Population-specific high total CED was calculated as 105.65 mSv. Multivariable binomial logistic regression model found that comorbid anxiety, chronic pain medication use, and diarrhea-predominant IBS were independently positively associated with population-specific high CED exposure. No significant temporal trend in peri-diagnostic mean CED was found. CONCLUSION: Patients with IBS receive high amounts of medical radiation, with 1 in 4 patients reaching at-risk levels of 50 mSv or more. Usage of pain medication at home, comorbid anxiety, and IBS-D are independently linked to an increased risk of high CED.

Characteristics and outcomes of COVID-19 in patients with HIV: a multicentre research network study.

OBJECTIVE: We studied clinical outcomes of COVID-19 infection in patients living with HIV (PLH) in comparison to non-HIV population. DESIGN: Analysis of a multicentre research network TriNETX was performed including patients more than 10 years of age diagnosed with COVID-19. METHODS: Outcomes in COVID-19 positive patients with concurrent HIV (PLH) were compared with a propensity-matched cohort of patients without HIV (non-PLH). RESULTS: Fifty thousand one hundred and sixty-seven patients with COVID-19 were identified (49,763 non-PLH, 404 PLH). PLH were more likely to be men, African-American, obese and have concurrent hypertension, diabetes, chronic kidney disease and nicotine dependence compared with non-PLH cohort (all P values <0.05). We performed 1 : 1 matching for BMI, diabetes, hypertension, chronic lung diseases, chronic kidney disease, race, history of nicotine dependence and sex. In unmatched analysis, PLH had higher mortality at 30 days [risk ratio 1.55, 95% confidence interval (95% CI): 1.01-2.39] and were more likely to need inpatient services (risk ratio 1.83, 95% CI: 1.496-2.24). After propensity score matching, no difference in mortality was noted (risk ratio 1.33, 95% CI: 0.69-2.57). A higher proportion of PLH group needed inpatient services (19.31 vs. 11.39%, risk ratio 1.696, 95% CI: 1.21-2.38). Mean C-reactive protein, ferritin, erythrocyte sedimentation rate and lactate dehydrogenase levels after COVID-19 diagnosis were not statistically different and mortality was not different for PLH with a history of antiretroviral treatment. CONCLUSION: Crude COVID-19 mortality is higher in PLH; however, propensity-matched analyses revealed no difference in outcomes, showing that higher mortality is driven by higher burden of comorbidities. Early diagnosis and intensive surveillance are needed to prevent a 'Syndemic' of diseases in this vulnerable cohort.

Skipping the Drip: Intravenous Proton Pump Inhibitor Bolus Therapy Leads to Poor Outcomes in High-Risk Bleeding.

Background and Aim The aim of this study was to evaluate the impact of a change in our institute's protocol from continuous intravenous (IV) proton pump inhibitor (PPI) therapy to bolus IV PPI therapy for the treatment of peptic ulcer-related bleeding on patient outcomes. Current guidelines recommend PPI therapy through high-dose IV bolus followed by continuous infusion for bleeding ulcers. Conflicting data have been reported regarding the practice shift to intermittent IV PPI therapy. Methods A retrospective record review was conducted of patients treated at West Virginia University between 2017 and 2018 for peptic ulcer related bleeding who underwent endoscopy and had high-risk stigmata. Relevant variables were identified. Outcomes were compared between groups based on PPI strategy. The primary endpoint was any poor outcome defined as rebleeding, need for embolization or surgery, or mortality during hospital stay. Results A total of 130 patients were included, with a mean age of 62.18 years. Continuous PPI infusion was used in 39.23%, whereas bolus IV PPI was used 60.76%. Poor outcome was encountered in 11 (21.57%) patients in the continuous and 33 (41.77%) patients in the bolus group (p = 0.028). On multivariable analyses, bolus PPI strategy was independently linked to poor outcome (Wald's odds ratio: 2.8; 95% CI: 1.21-6.84; p = 0.019) and an increased need for embolization/surgery (OR: 4.12, 95% CI: 1.14-19.99; p = 0.046). Conclusions IV bolus therapy showed worse outcomes compared with continuous IV PPI therapy for patients with peptic ulcer bleeding with high-risk features. More robust data are needed before a practice shift to bolus PPI may be appropriate.

Analysis of the Patient Information Quality and Readability on Esophagogastroduodenoscopy (EGD) on the Internet.

Objective: Patients are increasingly using the Internet to inform themselves of health-related topics and procedures, including EGD. We analyzed the quality of information and readability of websites after a search on 3 different search engines. Methods: We used an assessment tool for website quality analysis that we developed in addition to using validated instruments for website quality, Global Quality Score (GQS) and Health on Net (HON) certification. The readability was assessed using Flesch-Kincaid Reading Ease (FRE) and Flesch-Kincaid Grade level (FKG). 30 results of each search terms 'EGD' and 'Upper Endoscopy' from Google and 15 each from Bing and Yahoo were analyzed. A total of 45 websites were included from 100 URLs after removing duplicates, video links, and journal articles. Results: Only 3 websites were found to have good quality and comprehensive and authentic information. These websites were https://www.healthline.com, https://www.uptodate.com, and https://www.emedicine.medscape.com. There were additional 13 sites with moderate quality of information. The mean Flesch-Kincaid Reading Ease (FRE) score was 46.92 (range 81.6-6.5). The mean Flesch-Kincaid Grade level (FKG) was 11th grade, with a range of 6th grade to 12th grade and above making them difficult to read. Conclusions: Our study shows that there are quite a few websites with moderate quality content. We recommend 3 comprehensive and authentic websites out of 45 URLs analyzed for information on Internet for EGD. In addition, the readability of the websites was consistently at a higher level than recommended by AMA at 11th grade level. In addition, we identified 3 websites with moderate quality content written at 8th grade and below readability level. We feel that gastroenterologists can help their patients better understand this procedure by directing them to these comprehensive websites.
