AIM: To assess first-year gastroenterology fellows' ability to address difficult interpersonal situations in the workplace using objective structured clinical examinations (OSCE). METHODS: Two OSCEs ("distracted care team" and "frazzled intern") were created to assess response to disruptive behavior. In case 1, a fellow used a colonoscopy simulator while interacting with a standardized patient (SP), nurse, and attending physician all played by actors. The nurse and attending were instructed to display specific disruptive behavior and disregard the fellow unless requested to stop the disruptive behavior and focus on the patient and procedure. In case 2, the fellow was to calm an intern managing a patient with massive gastrointestinal bleeding. The objective in both scenarios was to assess the fellows' ability to perform their duties while managing the disruptive behavior displayed by the actor. The SPs used checklists to rate fellows' performances. The fellows completed a self-assessment survey. RESULTS: Twelve fellows from four gastrointestinal fellowship training programs participated in the OSCE. In the "distracted care team" case, one-third of the fellows interrupted the conflict and refocused attention to the patient. Half of the fellows were able to display professionalism despite the heated discussion nearby. Fellows scored lowest in the interprofessionalism portion of post-OSCE surveys, measuring their ability to handle the conflict. In the "frazzled intern" case, 68% of fellows were able to establish a calm and professional relationship with the SP. Despite this success, only half of the fellows were successfully communicate a plan to the SP and only a third scored "well done" in a domain that focused on allowing the intern to think through the case with the fellow's guidance. CONCLUSION: Fellows must receive training on how to approach disruptive behavior. OSCEs are a tool that can assess fellow skills and set a culture for open discussion.

OBJECTIVE: To examine whether ancestry influenced sex ratios of offspring in a birth cohort before parental antenatal sex selection influenced offspring sex. METHODS: We measured the sex ratio as the percent of males according to countries of birth of paternal and maternal grandfathers in 91,459 live births from 1964 to 1976 in the Jerusalem Perinatal Study. Confidence limits (CI) were computed based on an expected sex ratio of 1.05, which is 51.4% male. RESULTS: Of all live births recorded, 51.4% were male. Relative to Jewish ancestry (51.4% males), significantly more males (1,761) were born to Muslim ancestry (54.5, 95% CI = 52.1-56.8, P = 0.01). Among the former, sex ratios were not significantly associated with paternal or maternal age, education, or offspring's birth order. Consistent with a preference for male offspring, the sex ratio decreased despite increasing numbers of births over the 13-year period. Sex ratios were not affected by maternal or paternal origins in North Africa or Europe. However, the offspring whose paternal grandfathers were born in Western Asia included fewer males than expected (50.7, 50.1-51.3, P = 0.02), whether the father was born abroad (50.7) or in Israel (50.8). This was observed for descendents of paternal grandfathers born in Lebanon (47.6), Turkey (49.9), Yemen & Aden (50.2), Iraq (50.5), Afghanistan (50.5), Syria (50.6), and Cyprus (50.7); but not for those from India (51.5) or Iran (51.9). The West Asian group showed the strongest decline in sex ratios with increasing paternal family size. CONCLUSIONS: A decreased sex ratio associated with ancestry in Western Asia is consistent with reduced ability to bear sons by a subset of Jewish men in the Jerusalem cohort. Lower sex ratios may be because of pregnancy stress, which may be higher in this subgroup. Alternatively, a degrading Y chromosome haplogroup or other genetic or epigenetic differences on male germ lines could affect birth ratios, such as differential exposure to an environmental agent, dietary differences, or stress. Differential stopping behaviors that favor additional pregnancies following the birth of a daughter might exacerbate these lower sex ratios.

Purpose of Review Advances in medical therapy have resulted in a growing population of older adults with advanced heart failure. Frailty is a clinical syndrome that increases in prevalence with age and is highly prevalent in patients with heart failure. This paper reviews the complex relationship between frailty and advanced systolic heart failure in older adults, including the potential for reversal of frailty following advanced cardiac interventions. Recent Findings Frailty is predictive of adverse outcomes, including rehospitalization and mortality, in heart failure patients. Several small studies have shown that mechanical circulatory support can modify, and possibly reverse, functional impairments and the pathophysiologic changes associated with heart failure-related frailty. Summary Frailty is highly prevalent in patients with advanced heart failure and is a powerful prognostic marker. Routine frailty assessment could allow clinicians to define optimal patient-centered care strategies for older adult patients with advanced heart failure.

High-grade atrioventricular block (HAVB) is historically considered a marker of worse outcomes in patients with ST-segment elevation myocardial infarction (STEMI). However, the predictors and prognostic impact of HAVB in the primary percutaneous coronary intervention (PCI) era remain poorly understood. We sought to describe the characteristics and predictors of HAVB in patients undergoing primary PCI in STEMI and to assess the prognostic significance of HAVB in the contemporary reperfusion era. The present analysis includes 3,115 patients presenting with STEMI from the Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction trial who underwent primary PCI. Outcomes were examined according to the presence of HAVB on a presenting electrocardiogram, as interpreted by an independent electrocardiography core laboratory. HAVB (second-degree Mobitz II or third-degree atrioventricular block) was present at baseline in 46 patients (1.5%). Independent predictors of HAVB included increased age, diabetes mellitus, right coronary artery occlusion, sum of ST-segment deviation, and baseline Thrombolysis In Myocardial Infarction flow 0/1. Thrombolysis In Myocardial Infarction flow 3 was restored in 83.7% and 91.5% of patients with versus without baseline HAVB respectively (p = 0.06). Mortality rate was significantly higher in patients with versus without HAVB at 30-day, 1-, and 3-year follow-ups (unadjusted hazard ratio [HR] 3.83, 95% CI 1.40 to 10.48; unadjusted HR 4.37, 95% CI 2.09 to 9.38 and unadjusted HR 2.78, 95% CI 1.31 to 5.91, respectively). After covariate adjustment, mortality rate was significantly higher in patients with HAVB at 1 year (adjusted HR 2.45, 95% CI 1.09 to 5.50, p = 0.03) but not at 30 days (adjusted HR 1.70, 95% CI 0.58 to 5.01, p = 0.33) or 3 years (adjusted HR 0.71 to 3.41, p = 0.27). In conclusion, HAVB is a rare complication of STEMI but remains associated with increased mortality, even after primary PCI.

A 32-year-old Chinese woman sought care from our family medicine clinic because she had a headache, neck pain, and an intermittent cough that had produced white sputum for 7 days. She described the headache as severe and pressure-like, and said that it had progressively worsened over the previous 3 weeks, coinciding with her first trip outside of China to the United States. The patient indicated that she also had occasional vomiting, dizziness, a low-grade fever, chills, night sweats, and increasing fatigue.

Peptide receptor radionuclide therapy (PRRT) with [¹⁷⁷Lu-DOTA⁰,Tyr³]octreotate (¹⁷⁷Lu-DOTATATE) is a treatment with good results in patients with metastatic gastroenteropancreatic neuroendocrine tumours (GEPNETs). However, there are some pitfalls that should be taken into consideration when evaluating the treatment response after PRRT. 354 Dutch patients with GEPNETs who were treated with ¹⁷⁷Lu-DOTATATE between March 2000 and December 2011 were retrospectively selected. Liver function parameters and chromogranin A were measured before each therapy and in follow-up. Anatomical imaging was performed before therapy and in follow-up. An increase in aminotransferases by ≥20% compared to baseline was observed in 83 of 351 patients (24%). In patients with an objective response (OR) and stable disease (SD) this increase was observed in 71/297 (24%) and in patients with progressive disease (PD) it was observed in 12/54 patients (22%). An increase in chromogranin A by ≥20% compared to baseline was observed in 76 patients (29%). This was present in 34% of patients who eventually had PD and 27% of patients who had OR/SD. In 70% of patients this tumour marker returned to baseline levels after therapy. An increase in liver enzymes and chromogranin A is not uncommon after PRRT. In the vast majority of patients this will resolve in follow-up. Clinicians should be aware that these changes may occur due to radiation-induced inflammation or disease progression and that repeated measurements over time are necessary to differentiate between the two.

BACKGROUND: In 2012 The Joint Commission implemented new Tobacco Treatment (TOB) performance measures for hospitals. A study evaluated the impact of a hospital-based electronic health record (EHR) intervention on adherence to the revised TOB measures. METHODS: The study was conducted in two acute care hospitals in New York City. Data abstracted from the EHR were analyzed retrospectively from 4,871 smokers discharged between December 2012 and March 2015 to evaluate the impact of two interventions: an order set to prompt clinicians to prescribe pharmacotherapy and a nurse-delivered counseling module that automatically populated the nursing care plan for all smokers. The study estimated the relative odds of a patient being prescribed medication and/or receiving smoking cessation counseling in the intervention period compared to the baseline time period. RESULTS: There was a modest increase in medication orders (odds ratio [OR], 1.35). In contrast, rates of counseling increased 10-fold (OR, 10.54). Patients admitted through surgery were less likely to receive both counseling and medication compared with the medicine service. CONCLUSION: Hospitalization presents an important opportunity to engage smokers in treatment for primary and secondary prevention of tobacco-related illnesses. EHRs can be leveraged to facilitate integration of TOB measure requirements into routine inpatient care; however, the smaller effect on prescribing patterns suggests limitations in this approach alone in changing clinician behavior to meet this measure. The success of the nurse-focused EHR-driven intervention suggests an effective tool for integrating the cessation counseling component of the new measures and the importance of nursing's role in achieving the Joint Commission measure targets.
