Objective Peribiliary cysts are usually benign, although severe complications and mortality may occur, and they may be confounded with other diseases. No classification delineating their different characteristics exists. Design We performed a systematic review of the frequency and clinical manifestations of peribiliary cysts. Two reviewers identified studies after searching multiple databases on 2 August 2017. Results These cysts were prevalent in cirrhosis (9%). A total of 135 patients were reported in 72 papers with sufficient clinical data (10 countries, 65% from Japan, median age 63 years (range: 4–88), and 80% were males). Symptoms were present in 70%. Misdiagnosis occurred in 40%, and 33% underwent therapeutic misadventures. Cysts were solitary in 10%. Obstructive features and cholangitis were observed in 36% and 12.5%, respectively. Cysts progression was observed in 37.5% over a median of 18 months. Mortality was 24%, mostly due to cirrhosis. A classification framework is proposed, wherein type I includes hepatic, type II extrahepatic and type III mixed hepatic and extrahepatic cysts, each having distinct features. Specifically, type II was more frequent in females, solitary, without cirrhosis, presenting with obstructive jaundice, more difficult to diagnose and required more surgical interventions (all p<0.05). Conclusion Although rarely studied in the literature, peribiliary cysts were frequent in studies designed to evaluate their prevalence, and were mostly asymptomatic. Inaccurate diagnosis, therapeutic misadventures, cysts progression and cysts-related complications are frequent. In a novel classification framework based on location, extrahepatic peribiliary cysts have distinct characteristics and require a special approach for diagnosis and management.

Background The relationship between delayed gastric emptying and upper GI symptoms (UGI Sx) is controversial. Objective To assess association between gastric emptying and UGI Sx, independent of treatment. Design We performed a systematic review and meta-analysis of the literature from 2007 to 2017, review of references and additional papers identified by content expert. We included studies evaluating the association between gastric emptying and nausea, vomiting, early satiety/postprandial fullness, abdominal pain and bloating. Covariate analyses included optimal gastric emptying test method, gastric emptying type (breath test or scintigraphy) and patient category. Meta-regression compared the differences based on type of gastric emptying tests. Results Systematic review included 92 gastric emptying studies (26 breath test, 62 scintigraphy, 1 ultrasound and 3 wireless motility capsule); 25 of these studies provided quantitative data for meta-analysis (15 scintigraphy studies enrolling 4056 participants and 10 breath test studies enrolling 2231 participants). Meta-regression demonstrated a significant difference between optimal and suboptimal gastric emptying test methods when comparing delayed gastric emptying with nausea and vomiting. On evaluating studies using optimal gastric emptying test methodology, there were significant associations between gastric emptying and nausea (OR 1.6, 95% CI 1.4 to 1.8), vomiting (OR 2.0, 95% CI 1.6 to 2.7), abdominal pain (OR 1.5, 95% CI 1.0 to 2.2 ) and early satiety/fullness (OR 1.8, 95% CI 1.2 to 2.6) for patients with UGI Sx; gastric emptying and early satiety/fullness in patients with diabetes; gastric emptying and nausea in patients with gastroparesis. Conclusions The systematic review and meta-analysis supports an association between optimally measured delayed gastric emptying and UGI Sx.

The data on speckle-tracking echocardiography (STE) in patients with sepsis are limited. This systematic review from 1975 to 2016 included studies in adults and children evaluating cardiovascular dysfunction in sepsis, severe sepsis, and septic shock utilizing STE for systolic global longitudinal strain (GLS). The primary outcome was short- or long-term mortality. Given the significant methodological and statistical differences between published studies, combining the data using meta-analysis methods was not appropriate. A total of 120 studies were identified, with 5 studies (561 patients) included in the final analysis. All studies were prospective observational studies using the 2001 criteria for defining sepsis. Three studies demonstrated worse systolic GLS to be associated with higher mortality, whereas 2 did not show a statistically significant association. Various cutoffs between −10% and −17% were used to define abnormal GLS across studies. This systematic review revealed that STE may predict mortality in patients with sepsis; however, the strength of evidence is low due to heterogeneity in study populations, GLS technologies, cutoffs, and timing of STE. Further dedicated studies are needed to understand the optimal application of STE in patients with sepsis.

Study Design. Systematic review and meta-analysis of observational studies. Objective. The aim of the study is to evaluate different treatment modalities in the management of sacrococcygeal chordoma. Summary of Background Data. Chordomas are primary malignant bone tumors associated with considerable morbidity and mortality. Methods. We searched MEDLINE, EMBASE, Cochrane Central-Register of Controlled Trials, and Scopus from inception to July 2015. Eligible studies included patients with sacrococcygeal chordoma treated exclusively with surgery, radiotherapy, or both. Two reviewers independently assessed the eligibility of potential studies, risk of bias, and extracted data. Outcomes of interest were all-cause mortality, progression-free survival, and metastases. We analyzed further surgical outcomes by resection margin. All outcomes were assessed at 60 months and more than 60 months following intervention. Results. We included 33 noncomparative studies reporting on 501 patients (mean age 57 years). Overall mortality rate was (16%) after surgical resection with adjuvant radiotherapy and (28%) after surgical resection, and (43%) after radiotherapy (P = 0.28). All-cause mortality following wide surgical resection was (32%) compared to (40%) after marginal resection (P = 0.51). Overall progression-free survival rate was (58%) after surgical resection with adjuvant radiotherapy and (55%) after surgery (P = 0.92). However, at more than 60 months follow-up, progression-free survival rates were significantly higher (P = 0.024) following surgical resection with adjuvant radiotherapy (74%) in comparison to surgery (55%) and radiotherapy (36%). Overall progression-free survival rates were nonsignificantly higher after wide surgical resection (66%) than marginal resection (33%) (P = 0.16). However, at 60 months follow-up, progression-free survival rates were significantly higher following wide surgical resection (73%) than marginal resection (33%) (P = 0.047). Conclusion. Sacrococcygeal chordoma is a difficult to treat disease entity. Until comparative studies become available, wide surgical resection and multidisciplinary management are the recommended approaches to improve patient outcomes. Level of Evidence: 3

Background and Purpose— We aimed at providing estimates of mortality associated with cardiometabolic comorbidity and incident readmission from cardiometabolic as compared with noncardiometabolic conditions after a first transient ischemic attack. Methods— Between 2000 and 2015, patients hospitalized for a first transient ischemic attack were examined for cardiometabolic comorbidities (diabetes mellitus, coronary artery disease, heart failure, and atrial fibrillation), 5-year incident hospitalization, and time to death. Results— Of 251 patients with transient ischemic attack, 134 (53%) had at least 1 and 55 (22%) had at least 2 cardiometabolic conditions. By 5 years, 491 readmissions (134 [27%] cardiometabolic and 357 [73%] noncardiometabolic) and 75 deaths (27 [36%] cardiometabolic and 47 [64%] noncardiometabolic) were observed. Mortality was increased with any concurrent cardiometabolic comorbidity (hazard ratio, 1.89; 95% confidence interval, 1.17–3.03; P =0.0089) with multiplicative mortality risk from a combination of coronary artery disease and heart failure. Each hospitalization was associated with a 1.5-fold risk of death (95% confidence interval, 1.37–1.64; P <0.0001). Risk of cardiometabolic and noncardiometabolic mortality was correlated with the corresponding category-specific readmission. Conclusions— Among patients hospitalized for first transient ischemic attack, 5-year mortality is associated with concurrent cardiometabolic comorbidity and rates of subsequent hospitalization.

Background There is no consensus on the most effective and best tolerated first‐line antiarrhythmic treatment for fetal tachyarrhythmia. The purpose of this systematic review and meta‐analysis was to compare the efficacy, safety, and fetal–maternal tolerance of first‐line monotherapies for fetal supraventricular tachycardia and atrial flutter. Methods and Results A comprehensive search of several databases was conducted through January 2017. Only studies that made a direct comparison between first‐line treatments of fetal tachyarrhythmia were included. Outcomes of interest were termination of fetal tachyarrhythmia, fetal demise, and maternal complications. Ten studies met inclusion criteria, with 537 patients. Overall, 291 patients were treated with digoxin, 137 with flecainide, 102 with sotalol, and 7 with amiodarone. Digoxin achieved a lower rate of supraventricular tachycardia termination compared with flecainide (odds ratio [ OR ]: 0.773; 95% confidence interval [ CI ], 0.605–0.987; I 2 =34%). In fetuses with hydrops fetalis, digoxin had lower rates of tachycardia termination compared with flecainide ( OR : 0.412; 95% CI , 0.268–0.632; I 2 =0%). There was no significant difference in the incidence of maternal side effects between digoxin and flecainide groups ( OR : 1.134; 95% CI , 0.129–9.935; I 2 =80.79%). The incidence of maternal side effects was higher in patients treated with digoxin compared with sotalol ( OR : 3.148; 95% CI , 1.468–6.751; I 2 =0%). There was no difference in fetal demise between flecainide and digoxin ( OR : 0.767; 95% CI , 0.140–4.197; I 2 =44%). Conclusions Flecainide may be more effective treatment than digoxin as a first‐line treatment for fetal supraventricular tachycardia.

AbstractBackgroundThe implications of early readmission on long‐term mortality after transient ischemic attack (TIA) are not known. We aimed at examining the effect of 180‐day readmission on subsequent long‐term mortality after index hospitalization for TIA.MethodsA retrospective study of patients hospitalized for first‐ever TIA at Mayo Clinic from 2000 through 2017. Patients readmitted within 180 days postdischarge were compared with those not readmitted in long‐term risk of death.ResultsOf 251 TIA patients aged 73 ± 15 years with 1509 person‐years of follow‐up, 65 (26%) were readmitted within 180 days of discharge and 125 died during a median follow‐up of 5.7 years. The mortality was 10 vs. 7 deaths per 100 person‐years in patients who were readmitted compared to those who were not readmitted with hazard ratio (HR) 1.73 (95% confidence interval [CI] 1.13–2.66). Other competing predictors of mortality were age ≥65 years (HR 5.70, 95% CI 2.72–11.96), cancer (HR 1.65, 95% CI 1.03–3.38), chronic obstructive pulmonary disease (HR 1.90, 95% CI 1.07–3.38), heart failure (HR 3.03, 95% CI 1.82–5.06), dementia (HR 5.87, 95% CI 3.27–10.52), creatinine ≥1.4 mg/dl (HR 1.89, 95% CI 1.17–3.06), and hemoglobin level <10 g/dl (HR 2.80, 95% CI 1.20–6.66).ConclusionsHospital readmission within 180 days of discharge from index TIA was associated with increased risk of death several years after initial readmission. Older age and several comorbidities identified during index hospitalization also confer increased risk for long‐term mortality.

Hepatocellular carcinoma (HCC) is a complex disease most commonly arising in the background of chronic liver disease. In the past two decades, there has been a significant increase in our understanding of both the clinical and molecular heterogeneity of HCC. There has been a robust increase in clinical trial activity in patients with poor prognostic factors, such as macrovascular invasion and extrahepatic spread (EHS). We aimed to synthesize the evidence for the treatment of patients with advanced HCC based on these baseline characteristics, including patients with both Child‐Pugh (CP) scores of A and B. A comprehensive search of several databases from each database inception to February 15, 2016 any language was conducted. We included 14 studies (three randomized controlled studies [RCTs] and 11 observational studies). We included studies that compared sorafenib, transarterial bland embolization/transarterial chemoembolization, yttrium‐90/radiation therapy, ablation (or combination), and no therapy. Two RCTs comparing sorafenib to best supportive care demonstrated a consistent improvement in overall survival (OS) for patients with advanced HCC and metastatic vascular invasion (MVI) and/or EHS and CP A liver disease (hazard ratio, 0.66 [95% confidence interval, 0.51‐0.87]; I 2 = 0%). Several observational studies evaluated locoregional therapies alone or in combination with other treatments and were limited by very‐low‐quality of evidence. This was true for both patients with EHS and MVI. Conclusion : In patients with advanced HCC and CP A liver function, sorafenib is the only treatment that has been shown to improve OS in randomized studies. High‐quality data supporting the use of other treatment modalities in this setting, or in the setting of patients with less compensated (CP B) liver disease, are lacking.

Background Hospital discharge summaries enable communication between inpatient and outpatient physicians. Despite existing guidelines for discharge summaries, they are frequently suboptimal. Objective The aim of this study was to assess physicians’ perspectives about discharge summaries and the differences between summaries’ authors (hospitalists) and readers (primary care physicians [PCPs]). Methods A national survey of 1600 U.S. physicians was undertaken. Primary measures included physicians’ preferences in discharge summary standardization, content, format, and audience. Results A total of 815 physicians responded (response rate = 51%). Eighty-nine percent agreed that discharge summaries “should have a standardized format.” Most agreed that summaries should “document everything that was done, found, and recommended in the hospital” (64%) yet “only include details that are highly pertinent to the hospitalization” (66%). Although 74% perceived patients as an important audience of discharge summaries, only 43% agreed that summaries “should be written in language that patients…can easily understand,” and 68% agreed that it “should be written solely for provider-to-provider communication.” Compared with hospitalists, PCPs preferred comprehensive summaries (68% versus 59%, P = 0.002). More PCPs agreed that separate summaries should be created for patients and for provider-to-provider communication than hospitalists (60% versus 47%, P < 0.001). Compared with PCPs, more hospitalists believe that “hospitalists are too busy to prepare a high-quality discharge summary” (44% versus 23%, P < 0.001) and “PCPs have insufficient time to read an entire discharge summary” (60% versus 38%, P < 0.001). Conclusions Physicians believe that discharge summaries should have a standardized format but do not agree on how comprehensive or in what format they should be. Efforts are necessary to build consensus toward the ideal discharge summary.
