Effect of the number of passes on diagnostic performance of EUS-fine needle biopsy of solid pancreatic masses: A systematic review and meta-analysis.

BACKGROUND AND AIMS: The optimal number of passes to maximize the diagnostic ability of endoscopic ultrasound fine needle biopsy (EUS-FNB) of solid pancreatic masses (SPMs) is not well known. We conducted a systematic review to evaluate the impact of the incremental number of passes on diagnostic accuracy, tissue adequacy, and diagnostic yield for EUS-FNB of SPMs. METHODS: We searched MEDLINE, EMBASE, Scopus, and Cochrane Central for randomized controlled trials (RCTs) comparing per-pass diagnostic outcomes of FNB needles in patients with SPMs. Meta-analysis was conducted using random effects models. A separate analysis was performed on studies that used contemporary Franseen and fork-tip needles. RESULTS: Overall, 19 RCTs (N=3,552) were identified. For EUS-FNB of SPMs, three passes with any FNB needle outperformed two passes for accuracy (OR=1.58; 95%CI 1.20-2.09; I2=0%), adequacy (OR=1.97; 95%CI 1.30-2.83; I2=61%) and yield (OR=2.12; 95%CI 1.37-3.27; I2 14%). Adding a fourth or fifth pass resulted in no significant improvement in diagnostic parameters. When using contemporary FNB needles, adding a second to a single pass significantly improved accuracy (OR=1.80; 95%CI 1.23-2.63; I2=0%), adequacy (OR=2.19; 95% CI 1.65-2.90; I2=0%) and yield (OR=2.72; 95%CI 1.50-4.95; I2=0%). Adding a third pass to a second pass with contemporary needles improved adequacy (OR=2.96; 95%CI 1.97-4.46; I2=0%) but did not provide better diagnostic accuracy or yield. CONCLUSION: Two passes with Franseen or Fork-tip needles and three passes with any FNB needle suffice to provide optimal diagnostic performance for EUS-FNB of SPMs, without additional diagnostic benefits with more passes. Our results can inform future guidelines and quality benchmarks.

Management of Premenstrual Dysphoric Disorder: A Scoping Review.

Premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS) refer to physical, cognitive, or affective symptoms that arise in the late luteal phase and remit with menses. The present work is a clinically focused scoping review of the last twenty years of research on treatment for these disorders. A search of key terms using the PubMed/Medline, the Cochrane Library, Embase, and Web of Science databases was performed, and 194 studies of adult women met initial inclusion criteria for review. Research studies concerning medications, pharmacological and non-pharmacological complementary and alternative medicine treatments, and surgical interventions with the most available evidence were appraised and summarized. The most high-quality evidence can be found for the use of selective serotonin reuptake inhibitors (SSRIs) and combined oral contraceptives (COCs), with gonadotropin releasing hormone (GnRH) agonists and surgical interventions showing efficacy for refractory cases. While there is some evidence of the efficacy of alternative and complementary medicine treatments such as nutraceuticals, acupuncture, and yoga, variability in quality and methods of studies must be taken into account.

Endoscopic Treatment of Large Bile Duct Stones: A Systematic Review and Network Meta-Analysis.

BACKGROUND & AIMS: Several endoscopic methods have been proposed for the treatment of large biliary stones. We assessed the comparative efficacy of these treatments through a network meta-analysis. METHODS: Nineteen randomized controlled trials (2752 patients) comparing different treatments for management of large bile stones (>10 mm) (endoscopic sphincterotomy, balloon sphincteroplasty, sphincterotomy followed by endoscopic papillary large balloon dilation [S+EPLBD], mechanical lithotripsy, single-operator cholangioscopy [SOC]) with each other were identified. Study outcomes were the success rate of stone removal and the incidence of adverse events. We performed pairwise and network meta-analysis for all treatments, and used Grading of Recommendations, Assessment, Development, and Evaluation criteria to appraise the quality of evidence. RESULTS: All treatments except mechanical lithotripsy significantly outperformed sphincterotomy in terms of stone removal rate (risk ratio [RR], 1.03-1.29). SOC was superior to other adjunctive interventions (vs balloon sphincteroplasty [RR, 1.24; 95% CIs, 1.07-1.45], vs S+EPLBD [RR, 1.23; range, 1.06-1.42] and vs mechanical lithotripsy [RR, 1.34; range, 1.14-1.58]). Cholangioscopy ranked the highest in increasing the success rate of stone removal (surface under the cumulative ranking [SUCRA] score, 0.99) followed by S+EPLBD (SUCRA score, 0.68). SOC and S+EPLBD outperformed the other modalities when only studies reporting on stones greater than 15 mm were taken into consideration (SUCRA scores, 0.97 and 0.71, respectively). None of the assessed interventions was significantly different in terms of adverse event rate compared with endoscopic sphincterotomy or with other treatments. Post-ERCP pancreatitis and bleeding were the most frequent adverse events. CONCLUSIONS: Among patients with large bile stones, cholangioscopy represents the most effective method, in particular in patients with larger (>15 mm) stones, whereas S+EPLBD could represent a less expensive and more widely available alternative.

Glucocorticoid-Induced Hyperglycemia Including Dexamethasone-Associated Hyperglycemia in COVID-19 Infection: A Systematic Review.

OBJECTIVE: Optimal glucocorticoid-induced hyperglycemia (GCIH) management is unclear. The COVID-19 pandemic has made this issue more prominent because dexamethasone became the standard of care in patients needing respiratory support. This systematic review aimed to describe the management of GCIH and summarize available management strategies for dexamethasone-associated hyperglycemia in patients with COVID-19. METHODS: A systematic review was conducted using the PubMed/MEDLINE, Cochrane Library, Embase, and Web of Science databases with results from 2011 through January 2022. Keywords included synonyms for "steroid-induced diabetes" or "steroid-induced hyperglycemia." Randomized controlled trials (RCTs) were included for review of GCIH management. All studies focusing on dexamethasone-associated hyperglycemia in COVID-19 were included regardless of study quality. RESULTS: Initial search for non-COVID GCIH identified 1230 references. After screening and review, 33 articles were included in the non-COVID section of this systematic review. Initial search for COVID-19-related management of dexamethasone-associated hyperglycemia in COVID-19 identified 63 references, whereas 7 of these were included in the COVID-19 section. RCTs of management strategies were scarce, did not use standard definitions for hyperglycemia, evaluated a variety of treatment strategies with varying primary end points, and were generally not found to be effective except for Neutral Protamine Hagedorn insulin added to basal-bolus regimens. CONCLUSION: Few RCTs are available evaluating GCIH management. Further studies are needed to support the formulation of clinical guidelines for GCIH especially given the widespread use of dexamethasone during the COVID-19 pandemic.

Risk of Hepatocellular Carcinoma in Patients with Porphyria: A Systematic Review.

Acute porphyrias are a group of metabolic disorders resulting in defective porphyrin synthesis and reduced heme production, which carries a risk of malignancy. Porphyrias are inborn defects in the heme biosynthesis pathway resulting in neurovisceral manifestations and cutaneous photosensitivity attacks with multi-systemic involvement. Its estimated prevalence nears 5 per 100,000 patients worldwide. Subclinical liver disease is common, which can progress into transaminitis, fibrosis, cirrhosis, and malignancy. However, data on the incidence of primary liver cancer are lacking. We aim to determine the risk of hepatocellular carcinoma (HCC) in patients with porphyria. A systematic review and pooled analysis were conducted through 2021 on studies assessing blood tests, imaging, cancer development, liver transplant, surgical resection, and outcomes in porphyria. In total, 19 studies, which included 7381 patients with porphyria (3476 females), were considered for the final review. In eight studies, alpha-fetoprotein levels were elevated between 200 and 1000 IU/mL. Of the total cohort of patients with porphyria, primary liver cancer was diagnosed in 351 patients (4.8%), of whom 243 (3.3% of the total) were found to have HCC. A subset of patients was found to have cholangiocarcinoma (n = 18; 0.3% of the total). Interestingly, advanced liver disease or cirrhosis was not a prerequisite for the formation of HCC in a small group of patients. Of the total cohort, 30 patients underwent liver resection, 48 patients underwent liver transplantation, and 327 patients died. Patients with porphyria are at risk of developing primary liver malignancy. Further studies should aim to develop diagnostic and prognostic models aimed at the early detection of HCC in porphyria.

Comorbidity screening in hidradenitis suppurativa: Evidence-based recommendations from the US and Canadian Hidradenitis Suppurativa Foundations.

BACKGROUND: Hidradenitis suppurativa (HS) is associated with comorbidities that contribute to poor health, impaired life quality, and mortality risk. OBJECTIVE: To provide evidence-based screening recommendations for comorbidities linked to HS. METHODS: Systematic reviews were performed to summarize evidence on the prevalence and incidence of 30 comorbidities in patients with HS relative to the general population. The screening recommendation for each comorbidity was informed by the consistency and quality of existing studies, disease prevalence, and magnitude of association, as well as benefits, harms, and feasibility of screening. The level of evidence and strength of corresponding screening recommendation were graded by using the Strength of Recommendation Taxonomy (SORT) criteria. RESULTS: Screening is recommended for the following comorbidities: acne, dissecting cellulitis of the scalp, pilonidal disease, pyoderma gangrenosum, depression, generalized anxiety disorder, suicide, smoking, substance use disorder, polycystic ovary syndrome, obesity, dyslipidemia, diabetes mellitus, metabolic syndrome, hypertension, cardiovascular disease, inflammatory bowel disease, spondyloarthritis, and sexual dysfunction. It is also recommended to screen patients with Down syndrome for HS. The decision to screen for specific comorbidities may vary with patient risk factors. The role of the dermatologist in screening varies according to comorbidity. LIMITATIONS: Screening recommendations represent one component of a comprehensive care strategy. CONCLUSIONS: Dermatologists should support screening efforts to identify comorbid conditions in HS.

Association between pancreatic intraductal papillary mucinous neoplasms and extrapancreatic malignancies: A systematic review with meta-analysis.

BACKGROUND: It is unclear whether patients with intraductal papillary mucinous neoplasia harbor a higher risk of developing extrapancreatic malignancies. AIMS: We performed a pooled estimate of the incidence of extrapancreatic malignancies in patients with intraductal papillary mucinous neoplasia, with a particular focus on the comparison to the general population. METHODS: Computerized bibliographic search of main databases was performed through February 2021. The primary endpoint was the pooled incidence of extrapancreatic malignancies in patients with intraductal papillary mucinous neoplasms. Additional outcome was the comparison between intraductal papillary mucinous neoplasia patients and the general population, expressed in terms of standardized incidence ratio along with 95% confidence intervals. RESULTS: Eighteen studies with 8709 patients were included. The pooled rate of metachronous extrapancreatic malignancies was 10 (6-13)/1000 persons-year. No difference was observed according to intraductal papillary mucinous neoplasia histology and sex, whereas a significantly superior incidence of extrapancreatic malignancies was observed in patients with main-duct (36.7%, 25.4%-48%) as compared to branch-duct intraductal papillary mucinous neoplasia (26.2%, 17.6%-34.8%; p = 0.03). Pooled standardized incidence ratio comparing expected rates in the general population was 1.01 (0.79-1.29); no difference was observed concerning rates of metachronous gastric cancer (standardized incidence ratio 1.60, 0.72-3.54) and colorectal cancer (1.29, 0.92-1.18), whereas biliary cancer was observed more frequently in intraductal papillary mucinous neoplasia patients (2.29, 1.07-4.93). CONCLUSION: Patients with intraductal papillary mucinous neoplasia harbor an overall rate of extrapancreatic malignancies as high as 27.3%. The rate of metachronous extrapancreatic malignancies is not superior to the general population.

Systematic review with meta-analysis: bariatric surgery reduces the incidence of hepatocellular carcinoma.

BACKGROUND: Obesity is a risk factor for non-alcoholic steatohepatitis (NASH) and increases the risk of several cancer types including cancers of the liver. Bariatric surgery can provide durable weight loss, but little is known about the later development of hepatocellular carcinoma (HCC) after surgery. AIM: To determine whether bariatric surgery reduces the risk of HCC. METHODS: We performed a comprehensive literature search of major databases (from inception to November 2020) to identify studies which assess the incidence and risk of HCC following bariatric surgery. Pooled data were assessed using a random-effects model expressed in terms of odds ratio (OR), incidence rate ratio and 95% confidence interval (CI). RESULTS: Nine studies (two abstracts and seven full texts) were included for meta-analysis which involved 19 514 750 patients (18 423 546 controls and 1 091 204 bariatric patients). Pooled unadjusted odds ratio (OR) was 0.40 (95% CI: 0.28-0.57) which favoured bariatric surgery, though with high heterogeneity (I2 : 79%). Using an adjusted model derived from matched cohorts (five studies) yielded an OR of 0.63 (95% CI: 0.53-0.75) with moderate heterogeneity (I2 : 38%). The pooled rate/1000 person-years was 0.05 (95% CI: 0.02-0.07) in bariatric surgery patients and 0.34 (95% CI: 0.20-0.49) in the control group with an incidence rate ratio of 0.28 (95% CI: 0.18-0.42). CONCLUSION: Bariatric surgery is associated with a decreased risk of HCC.

Comparison of Adjuvant Chemotherapy for Upper Tract versus Lower Tract Urothelial Carcinoma: A Systematic Review and Meta-Analysis.

INTRODUCTION: Principles of management for upper tract urothelial carcinoma (UTUC) are mostly derived from knowledge of lower tract urothelial carcinoma (LTUC), however recent research indicates that these may be disparate diseases. In this review, we sought to compare the responsiveness of these tumors to similar treatment, platinum-based chemotherapy used in the adjuvant setting. MATERIALS AND METHODS: PubMed, EMBASE, and Web of Science were searched using a systematic search strategy. Disease-free survival (DFS), cancer-specific survival (CSS) and overall survival (OS) in patients with LTUC and UTUC treated with adjuvant chemotherapy were compared. Review Manager V 5.3 was used for meta-analyses. RESULTS: Adjuvant chemotherapy was associated with improved DFS (HR 0.41, 95%CI 0.31-0.54), CSS (HR 0.29, 95%CI 0.17-0.50) and OS (HR 0.51, 95%CI 0.38-0.70) rates in LTUC. The effectiveness of adjuvant chemotherapy in UTUC was less pronounced with respect to DFS (HR 0.61, 95%CI 0.1-0.93) and CSS (HR 0.70, 95%CI 0.56-0.90) rates, and there was no effect on OS (HR 0.87, 95%CI 0.69-1.10). Differences in CSS and OS were significant (p < 0.0001) in favor of adjuvant chemotherapy for LTUC versus UTUC. CONCLUSION: Despite similar histology, we found significant differences in responsiveness to adjuvant chemotherapy between LTUC and UTUC. This may add to the already growing knowledge that these are disparate diseases. Newer systemic treatments for urothelial carcinoma may prove more effective than platinum-based chemotherapy in the adjuvant setting for UTUC.

Clinician-Educator Tracks for Trainees in Graduate Medical Education: A Scoping Review.

PURPOSE: Clinician-educator tracks (CETs) appear to be increasing in prevalence in graduate medical education (GME) and may play an important role in medical education workforce development. The authors conducted a scoping review to characterize the current state of knowledge about CETs' structure, content, and outcomes. METHOD: Six databases were searched in January 2018 for English-language peer-reviewed articles published through 2017 to identify articles describing CETs in GME. To be included, the CET had to target GME learners (residents/fellows), be longitudinal, have the primary aim of developing trainees into clinician-educators (CEs), and address at least one CE core competency (direct teaching, curriculum development, mentorship/advising, leadership, assessment, educational scholarship). The authors extracted and analyzed data from included articles. RESULTS: Of 1,434 articles identified, 19 were included in the review, representing 18 separate CETs. All but 2 CETs (11%) were specialty-specific. Most included a core curriculum with classroom-based sessions (18; 100%), workplace-based opportunities to practice skills (17; 94%), and a required scholarly project (16; 89%). Seventeen (94%) focused on skills related to direct teaching. Four (22%) identified mentoring/advising as a core curriculum focus. Five (28%) required project dissemination. Time spent in CETs varied widely (median: 166 hours; range: 8 hours/4-month period to 1,288 hours/2-year period). The most common reported outcomes were learner reactions (7; 39%) and career tracking (11; 61%). CONCLUSIONS: This review yields a composite picture of the current state of CETs in GME. The results highlight the paucity of outcomes data and areas for potential standardization and future research.

Does Calculated Prognostic Estimation Lead to Different Outcomes Compared With Experience-Based Prognostication in the ICU? A Systematic Review.

Little is known about the impact of providing calculator/guideline based versus clinical experiential-based prognostic estimates to patients/caregivers in the ICU. We sought to determine whether studies have compared types of prognostic estimation in the ICU and associations with outcomes. DATA SOURCES: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, databases searched were PubMed, Embase, Web of Science, and Cochrane Library. The search was run on January 4, 2016, and April 12, 2017. References for included articles were searched. STUDY SELECTION: Studies meeting the following criteria were included in the analysis: communication of prognostic estimates, a comparator group, and in the adult ICU setting. DATA EXTRACTION: Titles/abstracts were reviewed by two researchers. We identified 10,704 articles of which 10 met inclusion criteria. Seven of the studies included estimates obtained from calculators/guidelines and three were based on subjective estimation wherein clinicians were asked to estimate prognosis based on experience. Only the seven using calculated/guideline based estimation were used for pooled analysis. Of these, one was a randomized trial, and six were nonrandomized before/after studies. All of the studies communicated the calculated/guideline-based estimates to the clinician. Two studies involved the communication of calculated prognostic estimates to the ICU physicians for all ICU patients. Four included identification of high-risk patients based on guidelines or review of historical local data which triggered a palliative care/ethics consultation, and one study included communication to physicians about guideline based likely outcomes for neurologic recovery for patients with out-of-hospital cardiac arrest survivors. The comparator arm in all studies was usual care without protocolized prognostication. DATA SYNTHESIS: Included studies were assessed for risk of bias. The most common outcomes measured were hospital mortality; do-not-resuscitate status; and medical ICU length of stay. In pooled analyses, there was an association between calculated/guideline based prognostic estimation and decreased medical ICU length of stay as well as increased do-not-resuscitate status, but no difference in hospital mortality. CONCLUSIONS: Protocolized assessment of calculator/guideline based prognosis in ICU patients is associated with decreased medical ICU length of stay and increased do-not-resuscitate status but does not have a significant effect on mortality. Future studies should explore how communicating these estimates to physicians changes behaviors including communication to patients/families and whether calculator/guideline based prognostication is associated with improved patient and family rated outcomes.

Home Telemonitoring In Heart Failure: A Systematic Review And Meta-Analysis.

We conducted a meta-analysis of twenty-six randomized controlled trials that tested the effectiveness of home telemonitoring in patients with heart failure for reducing mortality and hospital use. We used the PICOT framework as a tool to address an important variable not previously studied: the timing or duration of monitoring. Specifically, we found that home telemonitoring decreased the odds of all-cause mortality and heart failure-related mortality at 180 days but not at 365 days. Home telemonitoring did not significantly affect the odds of all-cause hospitalization at 90 or 180 days, or of heart failure-related hospitalization at 180 days. At 180 days, home telemonitoring significantly increased the odds of all-cause emergency department visits. Home care provision did not moderate the effects of home telemonitoring on all-cause hospitalization. Recent regulatory changes that relaxed Medicare restrictions on telehealth reimbursement make it imperative that studies fully describe outcomes (for example, heart failure-related versus all-cause hospitalizations) and deliberately test all essential intervention elements, such as intervention duration.

Is Shared Decision Making for End-of-Life Decisions Associated With Better Outcomes as Compared to Other Forms of Decision Making? A Systematic Literature Review.

Background: Whether shared decision making (SDM) has been evaluated for end-of-life (EOL) decisions as compared to other forms of decision making has not been studied. Purpose: To summarize the evidence on SDM being associated with better outcomes for EOL decision making, as compared to other forms of decision making. Data Sources: PubMed, Web of Science, Cochrane Central Register of Controlled Trials, EMBASE, PsycINFO, and CINAHL databases were searched through April 2014. Study Selection: Studies were selected that evaluated SDM, compared to any other decision making style, for an EOL decision. Data Extraction: Components of SDM tested, comparators to SDM, EOL decision being assessed, and outcomes measured. Data Synthesis: Seven studies met the inclusion criteria (three experimental and four observational studies). Results were analyzed using narrative synthesis. All three experimental studies compared SDM interventions to usual care. The four observational studies compared SDM to doctor-controlled decision making, or reported the correlation between level of SDM and outcomes. Components of SDM specified in each study differed widely, but the component most frequently included was presenting information on the risks/benefits of treatment choices (five of seven studies). The outcome most frequently measured was communication, although with different measurement tools. Other outcomes included decisional conflict, trust, satisfaction, and "quality of dying." Limitations: We could not analyze the strength of evidence for a given outcome due to heterogeneity in the outcomes reported and measurement tools. Conclusions: There is insufficient evidence supporting SDM being associated with improved outcomes for EOL decisions as opposed to other forms of decision making. Future studies should describe which components of SDM are being tested, outline the comparator decision making style, and use validated tools to measure outcomes.
