Geoepidemiologic variation in outcomes of primary sclerosing cholangitis

Primary sclerosing cholangitis (PSC) is a chronic, progressive, hepatobiliary disease characterized by inflammation and fibrosis of the intra- and extra-hepatic bile ducts. Its natural history is one that generally progresses towards cirrhosis, liver failure, cholangiocarcinoma, and ultimately disease-related death, with a median liver transplantation-free survival time of approximately 15-20 years. However, despite its lethal nature, PSC remains a heterogenous disease with significant variability in outcomes amongst different regions of the world. There are also many regions where the outcomes of PSC have not been studied, limiting the overall understanding of this disease worldwide. In this review, we present the geoepidemiologic variations in outcomes of PSC, with a focus on survival pre- and post-liver transplantation as well as the concurrence of inflammatory bowel disease and hepatobiliary neoplasia.     

Neonatal subgaleal hemorrhage unrelated to assisted vaginal delivery: clinical course and outcomes

The purpose of the study was to evaluate the occurrence of subgaleal hemorrhage (SGH) following non-assisted vaginal delivery (normal vaginal delivery or cesarean delivery), and to characterize associated factors, clinical course, and outcomes, compared to attempted assisted vaginal delivery (AVD)-associated SGH A retrospective cohort study was conducted. All cases of SGH encountered following delivery of a singleton neonate at Hadassah, Hebrew University Medical Center during 2011–2018 were included. Maternal, fetal, intrapartum, and neonatal characteristics and outcomes were compared between AVD-related and non-AVD-related SGH groups. The overall incidence of SGH was 4.5/1000 (369/82,256) singleton deliveries. The incidences of AVD- and non-AVD-related SGH were 44.6/1000 (350/7852) and 0.3/1000 (19/74,404) singleton deliveries, respectively. Ten (53%) of the 19 non-AVD-related SGH were diagnosed after vaginal delivery and 9 (47%) after an urgent cesarean section. SGH severity was mild, moderate, and severe in 68%, 16%, and 16% of the cases, respectively. SGH severity did not differ between the attempted AVD group and the non-AVD-related SGH group. A higher proportion of neonates with non-AVD SGH required phototherapy treatment than did those diagnosed with AVD-related SGH (56% vs. 24%, P = 0.003). Other neonatal outcomes, including Apgar scores, maximal bilirubin level, length of stay, and the rate of composite adverse outcomes, did not differ between the groups. SGH, although rare, may be diagnosed after unassisted vaginal or cesarean delivery in the absence of an AVD attempt. We advocate continuing education for all medical staff who participate in peripartum and neonatal care, regarding the possible occurrence of non-AVD-related SGH.     

The Psychological Effects of a Four-week Emergency Medicine Rotation on Residents in Training

Objective: To prospectively evaluate psychological stress reactions among residents in an emergency medicine (EM) rotation during a 4-week period.
Methods: Pre- and postrotation psychological distress levels were assessed over a 4-week EM rotation. Subjects were evaluated by several psychometric measures. These included the assessment of anxiety, depressive, and other psychological symptoms by the Brief Symptom Inventory (BSI), and the occurrence of traumatic anxiety via the Dissociative Experience Scale (DES). Also assessed were the Impact of Events Scale and the Holmes Social Readjustment Ratings Scale (Holmes), a baseline life-change measure. Demographic data were obtained. The study occurred in a university-affiliated teaching hospital ED. The 45 EM residents and 27 non-EM residents were analyzed as a group, followed by subgroup analysis comparing EM vs non-EM residents.
Results: An increase in psychological distress over the 4-week rotation was found in the non-EM group, but not in the EM group. For the non-EM residents, all 10 BSI scales worsened and 3 of 4 DES scales worsened (p = 0.002), indicative of increased psychological distress. In contrast, analysis of the 45 EM residents showed improvement in 8 of 10 BSI scales and 3 of 4 DES scales (p = 0.057).
Conclusion: A significant increase in psychologic distress was found among the non-EM residents during an EM rotation. The EM residents showed a trend for a decrease in psychological distress over the same 4-week period.     

Safety and efficacy of a 6 French perclose arterial suturing device following percutaneous coronary interventions: a pilot evaluation

BACKGROUND: Arterial access site management after percutaneous coronary intervention (PCI) is a matter of increasing importance in this era of potent antiplatelet pharmacotherapy. We evaluated the safety and efficacy of a 6 French (Fr) Perclose suturing device in achieving rapid hemostasis of the access site after PCI and thus improving patient comfort. METHODS: The 6 Fr Perclose (Prostar) device consists of a suture-based closure device delivered via introducer sheath designed for suturing of the arteriotomy puncture site. Over a 3-month period, the device was used in 48 consecutive PCI treated patients (age, 62 13 years; 70% male; 44% post myocardial infarction) and in-hospital groin complication rate was compared to 48 consecutive patients (age, 64 12 years; 64% male; 33% post myocardial infarction) who had manual compression hemostasis. RESULTS: Antiplatelet glycoprotein IIb/IIIa antagonists were used more frequently during and following the procedure in 58% of Perclose-treated patients versus 42% of the manual compression group (p = 0.019). Leg immobilization duration was 3 4 hours in all patients sutured by the device; in patients with manual compression, the sheath was removed at an average of 4.8 2.5 hours after termination of the PCI and an additional 6 hours of leg immobilization were subsequently required. No difference in overall major complication rate was found between groups (6.2% in suture-mediated patients versus 9.3% in manual compression group; p = 0.60). In 3 patients (6.2%) treated using the device, adjunctive manual compression was required in addition to groin suturing due to technical failure or residual oozing from the arteriotomy site. CONCLUSION: The 6 Fr Perclose device can be safely used to achieve rapid hemostasis and the device may hasten bed mobilization of PCI-treated patients despite frequent use of potent antiplatelet pharmacotherapy during coronary interventions.     

Coronary stenting without predilatation (SWOP): applicable technique in everyday practice.

To evaluate the feasibility of stenting without predilatation, we registered all interventional procedures over a 6-month period. Six hundred patients were registered, and 684 lesions were treated. Interventions were divided into four groups: stenting without predilatation (SWOP), 221 lesions (32.4%); primary stenting with predilatation (PDS), 161 lesions (23.5%); provisional stenting (PRS), 131 lesions (19.2%); and plain-old balloon angioplasty (POBA), 171 lesions (25%). Interventional strategy was at the discretion of the operator based on few simple angiographic criteria and his clinical judgment. Procedural success was similar in all stent groups. We conclude that when primary stenting is planned, about 60% of lesions can be treated by SWOP effectively with excellent procedural results and considerable cost saving.
