Prevalence of endoscopy-related injuries and their impact on clinical practice: a systematic review and meta-analysis.

BACKGROUND: Endoscopy-related musculoskeletal injuries (ERIs) are commonly reported but their exact prevalence and clinical impact remain obscure. We conducted a systematic review and meta-analysis of the current literature aiming to answer these questions. METHODS: The MEDLINE, EMBASE, and SCOPUS databases were searched for studies evaluating ERIs in gastroenterologists and surgeons. The co-primary outcome was the prevalence of ERIs (i.e. carpal tunnel syndrome, de Quervain's tenosynovitis, and hand numbness). The second co-primary outcome was the prevalence of endoscopy-related pain syndromes. RESULTS: 12 studies, including 4563 respondents, were included. The majority of respondents were men (n = 3321; 72.8%) and most were right-handed (86.2%). The career prevalence of carpal tunnel syndrome (pooled from 10 studies) was 5.3% (95%CI 1.5%-8.9%; I 2 = 97.1%), while the prevalence of de Quervain's tenosynovitis (five studies) was 8.5% (95%CI 0.1%-17.0%). The pooled prevalences of thumb pain, neck pain, and back pain were 25.4%, 23.1%, and 19.7%, respectively, but the prevalence varied according to the type of questionnaire used. Only 341/864 respondents (39.5%) had received prior training in ergonomics, while 623/889 respondents (70.1%) expressed a desire for further training in ergonomics. Overall, there is a moderate risk of bias in the present literature. CONCLUSION: ERIs, including carpal tunnel syndrome, de Quervain's tenosynovitis, and endoscopy-related pain, are very common. These injuries can be severe, requiring surgery, and lead to loss of productivity. Most gastroenterologists report an unmet need for training in the proper ergonomics of endoscopy.

Occurrence of gastric cancer in patients with juvenile polyposis syndrome: a systematic review and meta-analysis.

BACKGROUND AND AIMS: The true rate of gastric cancer (GC) in juvenile polyposis syndrome (JPS) is unknown because of its rarity and ascertainment bias in published literature. To better assess this, we conducted a systematic review and meta-analysis. METHODS: MEDLINE, Embase, and Scopus databases were searched for the key words juvenile polyposis syndrome, juvenile polyps, stomach cancer, GC, SMAD4, BMPR1A, hamartomatous polyposis syndrome, hamartomas, and hereditary cancers for studies reporting upper GI manifestations in JPS. The primary outcome was the reported occurrence of GC in JPS. We then compared GC occurrence based on the presence or absence of pathogenic germline variants (PGVs) and in untested patients. RESULTS: Eleven studies including 637 patients were included. The pooled occurrence of GC was 3.5% (95% confidence interval [CI], 1.8-5.2; I2 = 12.3%) at a median age of 42.5 years (range, 15-57.6). The pooled occurrence of GC in patients with SMAD4 PGV was 10.1% (95% CI, 3.2-16.8%; I2 = 54.7%). GC was reported in only 1 BMPR1A PGV carrier and was not reported in patients without an identifiable PGV. In patients with prior germline testing, the risk of GC was higher in SMAD4 PGV carriers (odds ratio, 11.6; 95% CI, 4.6-29.4; I2 = 18.3%) compared with patients without SMAD4 PGV. In JPS patients with unknown status of germline testing, pooled occurrence of GC was 7.5% (95% CI, 0-15.5). There was an overall moderate risk of bias in the studies. CONCLUSIONS: GC is highest in SMAD4-associated JPS and was not reported in patients without identifiable PGVs. The value of GC surveillance in BMPR1A PGV carriers and JPS patients without an identifiable PGV is questionable. Germline testing should be performed in all JPS patients to inform GC risk discussion and utility of surveillance.

Incidence and risk factors for recurrence of ampullary adenomas after endoscopic papillectomy: Comparative analysis of familial adenomatous polyposis and sporadic ampullary adenomas in an international multicenter cohort.

OBJECTIVES: Endoscopic papillectomy (EP) is a minimally invasive therapy for the management of ampullary adenomas (AA). We conducted this multicenter study to assess the incidence of and factors related to the recurrence of AA after EP in patients with familial adenomatous polyposis (FAP) compared to sporadic AA. METHODS: We included patients who underwent EP for AA at 10 tertiary hospitals. Adenomatous tissue at the resection site at the time of surveillance endoscopies was considered recurrent disease. RESULTS: In all, 257 patients, 100 (38.9%) with FAP and 157 (61%) patients with sporadic AA, were included. Over a median of 31 (range, 11-61) months, recurrence occurred in 48/100 (48%) of patients with FAP and 58/157 (36.9%) with sporadic AA (P = 0.07). Two (2%) FAP patients and 10 (6.3%) patients with sporadic AA underwent surgery for recurrence. On multivariable regression analysis, the recurrence in FAP was higher than in sporadic patients after the first year of follow-up. AA size (hazard ratio [HR] 1.03, 95% confidence interval [CI] 1.001, 1.056), periampullary extension (HR 2.5, 95% CI 1.5, 4.01), and biliary duct dilation (HR 2.04, 95% CI 1.2, 3.4) increased the risk, while en bloc resection (HR 0.6, 95% CI 0.41, 0.9) decreased the risk of recurrence. CONCLUSION: Recurrence rates are high after EP. Most recurrences in sporadic patients occur within the first year of follow-up, but after the first year of follow-up in patients with FAP. Recurrences are higher with larger adenomas, biliary duct dilation, and periampullary extensions, and may be mitigated by en bloc resection. These factors should be considered in decision-making with the patients.

Natural history of ampullary adenomas in familial adenomatous polyposis: a long-term follow-up study.

BACKGROUND AND AIMS: Ampullary adenomas (AAs), common in familial adenomatous polyposis (FAP), are precursors to ampullary carcinoma. We assessed the natural history of AAs and factors associated with clinically significant progression (CSP). METHODS: Consecutive FAP patients with AAs and at least 2 EGDs were identified from a hereditary GI cancer registry. We assessed the incidence of CSP (increase in size to ≥10 mm and/or development of advanced histology) of AAs. Clinical, endoscopic, and pathologic features between patients with CSP and nonprogressors were compared. RESULTS: One hundred forty-three patients with AAs were included. Over a median follow-up of 7.8 years (interquartile range, 4.3-11.1), 41 patients (28.6%) developed CSP for an incidence of 35 per 1000 patient-years. Of 143 patients, 22 (15.6%) progressed to AAs ≥10 mm, 12 (8.5%) progressed to advanced histology, and 7 (4.9%) progressed both in size and histology. Two patients (1.4%) developed ampullary cancer. Male gender, abnormal appearance of the papilla at initial AA detection, prior cholecystectomy, and personal history of extracolonic malignancy were associated with CSP. Neither Spigelman stage nor the adenomatous polyposis coli gene pathogenic variants were associated with CSP. An intervention specifically for AA and not duodenal polyposis was performed in 24% of patients with AAs, including endoscopic papillectomy in 23 patients and duodenectomy in 3 patients at a median observation of 8.2 years. CONCLUSIONS: Most FAP patients with AAs did not experience CSP or require resection over 8 years of surveillance. Ampullary cancer was rare. Male gender, abnormal appearance of the papilla at AA detection, cholecystectomy, and history of extracolonic malignancy were associated with CSP. Our findings favor endoscopic surveillance of AAs over expedited resection for most patients with FAP.

Diagnostic accuracy of EUS-guided fine-needle biopsy sampling by macroscopic on-site evaluation: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Assessment of EUS-guided fine-needle tissue acquisition by macroscopic on-site evaluation (MOSE) is gathering attention. Studies report good diagnostic parameters with MOSE; however, the overall data are limited. We conducted this systematic review and meta-analysis to report on the pooled diagnostic assessment parameters of EUS-guided tissue acquisition by MOSE using fine-needle biopsy sampling (FNB). METHODS: Multiple databases were searched (from inception to December 2021), and studies that reported on the diagnostic assessment of EUS-guided tissue acquisition by MOSE were selected. Pooled diagnostic accuracy, sensitivity, specificity, and positive and negative predictive values were calculated by standard meta-analysis methods following the random-effects model. Heterogeneity was assessed by I2 statistics. RESULTS: Fourteen studies were included in the analysis, and 1508 lesions were biopsy sampled in 1489 patients undergoing EUS-guided tissue acquisition. MOSE definition included a visible core of tissue with opacity and "wormlike" features of adequate size and length (≥4 mm). The pooled accuracy of FNA and/or FNB specimens in yielding a pathologic diagnosis by MOSE was 91.3% (95% confidence interval [CI], 88.6-93.3; I2 = 66%), pooled sensitivity was 91.5% (95% CI, 88.6-93.6; I2 = 66%), pooled specificity was 98.9% (95% CI, 96.6-99.7; I2 = 80%), pooled positive predictive value was 98.8% (95% CI, 97.4-99.5; I2 = 33%), and pooled negative predictive value was 55.5% (95% CI, 46.9-63.9; I2 = 95%). Subgroup analyses by newer-generation FNB needles demonstrated similar pooled rates, with minimal adverse events (2.5%; 95% CI, 1.5-3.9; I2 = 21%). CONCLUSIONS: Excellent pooled diagnostic accuracy parameters were demonstrated in EUS-guided tissue acquisition by FNB using the MOSE method.

The Prevalence of the Celiac Disease in Patients with Dyspepsia: A Systematic Review and Meta-Analysis.

BACKGROUND: Patients with celiac disease (CeD) can commonly present with symptoms of dyspepsia. We conducted a systematic review and meta-analysis of the present literature to assess the prevalence of CeD in patients diagnosed with dyspepsia. METHODS: We searched MEDLINE and EMBASE databases for the keywords: celiac disease, coeliac disease, anti-gliadin, tissue transglutaminase antibody, anti-endomysial antibody, dyspepsia and functional gastrointestinal disorder. All the studies published from January 1991 till May 2021 were included. Diagnosis of CeD was based on the European Society of Pediatric Gastroenterology, Hepatology and Nutrition guidelines. A random-effects model was used to pool the data. RESULTS: Twenty-one studies screening 10,275 patients with dyspepsia were included. The pooled seroprevalence of CeD based on a positive anti-tissue transglutaminase antibody and/or anti-endomysial antibody was 4.8% (95% CI [2.8, 6.7%], I2 = 87.7%). The pooled biopsy-confirmed CeD prevalence was 1.5% (95% CI [1.0, 1.9%]; I2 = 59.8%) in these patients. Both seroprevalence (Odds ratio: 1.8; 95% CI [0.8, 4.0%]; I2 = 0%) and prevalence of biopsy-confirmed CeD (Odds ratio: 1.4; 95% CI [0.8, 2.4]; I2 = 0%) were not higher in patients with dyspepsia compared to controls. There was a moderate risk of selection bias and significant heterogeneity in the pooled results. CONCLUSIONS: The pooled prevalence of CeD in patients with dyspepsia was 1.5% and it was not significantly higher than the general population. These results do not support screening of patients with dyspepsia for CeD.

Impact of Cirrhotic Cardiomyopathy Diagnosed According to Different Criteria on Patients with Cirrhosis Awaiting Liver Transplantation: A Retrospective Cohort Study.

BACKGROUND: Recently, the Cirrhotic Cardiomyopathy Consortium (Consortium) proposed criteria to replace the World Congress of Gastroenterology (WGO) criteria for cirrhotic cardiomyopathy (CCM) using contemporary echocardiography parameters. We assessed the impact of substituting WGO by Consortium criteria on the frequency of diagnosis and clinical outcomes in patients with cirrhosis awaiting liver transplantation (LT). METHODS: Consecutive adults with cirrhosis approved for LT with echocardiography evaluation from January 2014 to December 2016 were screened. Patients with structural heart diseases were excluded. Two primary outcomes were: (1) frequency of CCM; (2) association of CCM with pre-transplant mortality. The secondary outcomes were pre-LT complications of acute kidney injury (AKI) and/or hepatic encephalopathy (HE), and post-LT mortality. RESULTS: Of 386 patients screened, 278 were included. 238 (85.6%) and 208 (74.8%) patients met Consortium and WGO criteria, respectively; 180 (64.7%) patients fulfilled both the criteria, while 12 (4.3%) patients had no evidence of CCM by either criterion. Pre-LT mortality rates in Consortium-CCM group were similar to the other groups (19.3% vs 20.2% vs 25.0%). The patients with advanced diastolic dysfunction (DD) per Consortium-CCM criteria had higher mortality than the other groups. The rates of pre-LT AKI/HE rates and post-LT mortality were similar in Consortium-CCM and WGO-CCM groups. CONCLUSION: The Consortium criteria do not impact the prevalence of CCM compared to WGO criteria and have similar predictive accuracy. Presence of advanced DD per the Consortium criteria increases the risk of pre-LT mortality and complications of AKI/HE. The patients with advanced DD could benefit from further monitoring and treatment.

Implementing a telemedicine curriculum for internal medicine residents during a pandemic: the Cleveland Clinic experience.

Telemedicine training was not a substantial element of most residency programmes prior to the COVID-19 pandemic. Social distancing measures changed this. The Cleveland Clinic Internal Medicine Residency Programme (IMRP) is one of the largest programmes in the USA, which made the task of implementing a telemedicine curriculum more complex. Here we describe our experience implementing an effective, expedited telemedicine curriculum for our ambulatory resident clinics. This study was started in April 2020 when we implemented a resident-led curriculum and training programme for providing ambulatory telemedicine care. The curriculum was finalised in less than 5 weeks. It entailed introducing a formal training programme for residents, creating a resource guide for different video communication tools and training preceptors to safely supervise care in this new paradigm. Residents were surveyed before the curriculum to assess prior experience with telemedicine, and then afterward to assess the curriculum's effectiveness. We also created a mini-CEX assessment for residents to solicit feedback on their performance during virtual appointments. Over 2000 virtual visits were performed by residents in a span of 10 weeks. Of 148 residents, 38% responded to the pre-participation survey. A majority had no prior telemedicine experience and expressed only slight comfort with the modality. Through collaboration with experienced residents and faculty, we expeditiously deployed an enhancement to our ambulatory care curriculum to teach residents how to provide virtual care and help faculty with supervision. We share our insights on this experience for other residency programmes to use.

Real-world re-treatment outcomes of direct-acting antiviral therapy failure in patients with chronic hepatitis C.

Direct-acting antiviral (DAA) drugs are associated with high (>95%) sustained virological response at 12 weeks (SVR12) in chronic hepatitis C (CHC) patients. There is a paucity of data regarding the characteristics and re-treatment outcomes of DAA treatment failure patients. In a retrospective analysis of the prospectively collected database, we assessed the outcomes of re-treatment among patients with previous DAA failure. Patients' characteristics, viral characteristics, including resistance-associated substitutions (RAS) in a subgroup of patients, SVR12, and clinical outcomes were studied. Of 40 patients with DAA failure, among whom 36 were retreated, mean age was 45.7 years, 63.9% (n = 23) were male, 63.9% (n = 23) had a genotype-3 infection and 63.9% (n = 23) were cirrhotic. The re-treatment regimens included a combination of pan-genotypic DAA, mainly sofosbuvir and velpatasvir with or without ribavirin. Three patients who declined retreatment and one who was still on treatment was excluded. For patients who completed re-treatment, SVR12 was 100% irrespective of genotypes. SVR12 among genotype 3 was 75% (15 of 20) when lost to follow-up was considered a treatment failure. Six patients died due to liver-related causes, including five (83.3%) with hepatocellular carcinoma. RAS analysis in 17 randomly selected patients did not reveal any dominant substitutions in NS5A or NS5B region affecting SVR12, though several novel mutations were observed. In conclusion, re-treatment of CHC patients with prior DAA failure using pan-genotypic DAA is associated with high SVR12 rates irrespective of genotype or the presence of RAS.

Prevalence of celiac disease in patients with short stature: A systematic review and meta-analysis.

BACKGROUND AND AIM: Short stature is a common extraintestinal manifestation of celiac disease (CeD). We conducted a systematic review and meta-analysis to assess the global prevalence of CeD in patients presenting with short stature. METHODS: We searched Medline and EMBASE databases for the keywords "celiac disease, coeliac disease, anti-gliadin, tissue transglutaminase antibody, anti-endomysial antibody, short stature and growth retardation." All the studies published from January 1991 to May 2020 were included. Patients without any prior evaluation for short stature were classified as all-cause short stature, while prior evaluated patients, where no cause was found for short stature, were classified as idiopathic short stature. The diagnosis of CeD was based on the European Society for Paediatric Gastroenterology, Hepatology and Nutrition guidelines. A random-effects model was used to pool the data. RESULTS: Seventeen studies screening 3759 patients (1582 with all-cause short stature and 2177 with idiopathic short stature) were included. The pooled seroprevalence of CeD based on positive anti-tissue transglutaminase antibody and anti-endomysial antibody was 11.2% (95% CI 4.0-21.2%; I2  = 86%) and 9.7% (95% CI 2.7-20.2%; I2  = 95%) for all-cause and idiopathic short stature, respectively. Similarly, pooled prevalence of biopsy-confirmed CeD was 7.4% (95% CI 4.7-10.6%; I2  = 76%) and 11.6% (95% CI 4.1-22.2%; I2  = 97%), for all-cause and idiopathic short stature, respectively. There was an overall severe risk of selection bias and significant heterogeneity in the pooled results. CONCLUSIONS: Approximately one in 14 patients with all-cause short stature and one in nine patients with idiopathic short stature had biopsy-confirmed CeD. Therefore, evaluation for CeD may be prudent in all patients with short stature.

A Randomized Control Trial of Thromboelastography-Guided Transfusion in Cirrhosis for High-Risk Invasive Liver-Related Procedures.

BACKGROUND AND AIM: Hemostasis in cirrhosis is dynamic and balanced. Thromboelastography (TEG) assesses global coagulation status. We aimed to assess whether TEG-guided blood product transfusions result in lower blood product requirements in patients with cirrhosis undergoing invasive liver-related procedures as compared to the conventional standard of care (SOC). METHODS: In this open-label, randomized controlled trial, cirrhosis patients with coagulopathy, undergoing invasive liver-related procedures, were randomized to either TEG-guided blood product transfusion or SOC. The primary outcome was difference in the amount of fresh frozen plasma (FFP) and platelet units transfused between the two groups. The secondary outcome was procedure-related bleeding complications within 5 days and any complications until 28 days. RESULTS: From November 2017 till June 2019, 58 patients were recruited (29: TEG and 29: SOC). Most common procedures performed were percutaneous liver biopsy (n = 48), followed by transjugular intrahepatic portosystemic shunt (n = 2), percutaneous acetic acid injection (n = 2), and transarterial chemoembolization (n = 2). There were no differences in baseline demographics, hemostatic profile, and types of procedures between the two groups. Only nine patients in TEG group received transfusions compared to all patients in SOC (31% vs 100%; P < 0.001). In TEG group, six (20.7%) received FFP (P = 0.753 vs. SOC), two (6.9%) received platelets (P < 0.001 vs. SOC), and 1(3.4%) patient received both FFP and platelet (P ≥ 0.999 vs. SOC) transfusion. None of the patients in either group developed procedure-related bleeding complications until 5 days post-procedure. The complication rates at 28-day follow-up were similar between the groups. CONCLUSION: TEG-guided blood product transfusion strategy reduces blood product transfusion without increased risk of bleeding in cirrhotic patients undergoing invasive liver-related procedures (CTRI/2017/12/010822).

Interventions to reduce aggressive care at end of life among patients with cancer: a systematic review.

Little is known about effective interventions to reduce aggressive end-of-life care in patients with cancer. We did a systematic review to assess what interventions are associated with reductions in aggressive end-of-life cancer care. We searched MEDLINE, CINAHL, Embase, Scopus, and PsychINFO for randomised control trials (RCTs), quasi-experimental, and observational studies published before Jan 19, 2018, which aimed to improve measures of aggressive end-of-life care for patients with cancer. We developed a taxonomy of interventions using the Systems Engineering Initiative for Patient Safety (SEIPS) model to summarise existing interventions that addressed aggressive care for patients with cancer. Of the 6451 studies identified by our search, five RCTs and 31 observational studies met the final inclusion criteria. Using the SEIPS framework, 16 subcategories of interventions were identified. With the exception of documentation of end-of-life discussions in the electronic medical record, no single intervention type or SEIPS domain led to consistent improvements in aggressive end-of-life care measures. The ability to discern the interventions' effectiveness was limited by inconsistent use of validated measures of aggressive care. Seven (23%) of 31 observational studies and no RCTs were at low risk of bias according to Cochrane's Risk of Bias tool. Evidence for improving aggressive end-of-life cancer care is limited by the absence of standardised measurements and poor study design. Policies and studies to address the gaps present in end-of-life care for cancer are necessary.

Impact of tuberculosis on glycaemic status: A neglected association.

Background & objectives: Diabetes mellitus (DM) is an important risk factor for tuberculosis and has received increasing emphasis. However, the reverse association of tuberculosis impacting blood sugar levels has not been well studied. The present study was conducted to evaluate the prevalence of hyperglycemia in patients with tuberculosis and assess its resolution following successful treatment of tuberculosis. Methods: In this prospective study, a total of 582 patients with tuberculosis were evaluated for hyperglycaemia [DM or impaired glucose tolerance (IGT)] with random blood sugar (RBS) and all patients with RBS >100 mg/dl were subjected to a 75 g oral glucose tolerance test (OGTT). All patients received thrice weekly intermittent Directly Observed Treatment Short Course (DOTS) for tuberculosis. Patients with hyperglycaemia were re-evaluated at the end of anti-tuberculosis treatment with an OGTT and glycated hemoglobin (HbA1c) levels to assess for glycaemic status. Results: In the present study, 41 of the 582 patients were found to have DM [7%, 95% confidence interval (CI) (5.2, 9.4)] while 26 patients were found to have IGT [4.5%, 95% CI (3, 6.5)]. Three patients were lost to follow up. Of the 26 patients with IGT, 17 [65.4%, 95% CI (46.1, 80.7)] reverted to euglycaemic status following successful treatment of tuberculosis, while the blood sugar levels improved in all patients with DM following treatment of tuberculosis. Interpretation & conclusions: Our study results show that tuberculosis adversely impacts glycaemic status with improvement in blood sugar levels at the end of successful treatment of tuberculosis. Longitudinal studies with large sample size are required to confirm these findings.

Index-TB guidelines: Guidelines on extrapulmonary tuberculosis for India.

Extrapulmonary tuberculosis (EPTB) is frequently a diagnostic and therapeutic challenge. It is a common opportunistic infection in people living with HIV/AIDS and other immunocompromised states such as diabetes mellitus and malnutrition. There is a paucity of data from clinical trials in EPTB and most of the information regarding diagnosis and management is extrapolated from pulmonary TB. Further, there are no formal national or international guidelines on EPTB. To address these concerns, Indian EPTB guidelines were developed under the auspices of Central TB Division and Directorate of Health Services, Ministry of Health and Family Welfare, Government of India. The objective was to provide guidance on uniform, evidence-informed practices for suspecting, diagnosing and managing EPTB at all levels of healthcare delivery. The guidelines describe agreed principles relevant to 10 key areas of EPTB which are complementary to the existing country standards of TB care and technical operational guidelines for pulmonary TB. These guidelines provide recommendations on three priority areas for EPTB: (i) use of Xpert MTB/RIF in diagnosis, (ii) use of adjunct corticosteroids in treatment, and (iii) duration of treatment. The guidelines were developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria, which were evidence based, and due consideration was given to various healthcare settings across India. Further, for those forms of EPTB in which evidence regarding best practice was lacking, clinical practice points were developed by consensus on accumulated knowledge and experience of specialists who participated in the working groups. This would also reflect the needs of healthcare providers and develop a platform for future research.

An Interesting Case of Recurrent Pyelonephritis.

A 35-year-old male presented with repeated episodes of fever and abdominal pain of 3-month duration. He had been hospitalized twice with similar complaints in the past 3-month. He was diagnosed as pyelonephritis and managed with intravenous antibiotics. However, fever recurred after ten days of discharge from the hospital. With these complaints, he was referred to the Department of Medicine, AIIMS, New Delhi. After evaluation, he was diagnosed as pyelonephritis with right sided consolidation and was started on broad spectrum antibiotics. After a transient initial improvement, his dyspnea worsened, fever recurred and he developed a tender submandibular abscess. Further evaluation for the actual focus of infection, revealed a small mass attached to the right coronary aortic cusp on transthoracic ECHO. Diagnosis of native Aortic valve endocarditis was made and suitably treated. The patient became afebrile on the 8th day of therapy and was discharged after 20-day. He is doing well on subsequent follow-up.
