Chromatin function in telomeres is poorly understood, but it is generally viewed as repressive. Yet, telomeric DNA sequences are transcribed into long non-coding RNAs named TElomere Repeat-containing RNA (TERRA). As TERRA molecules mostly localize at telomeres, major research efforts have been made to understand their functions, and how TERRA transcription is regulated and affects telomere structure. This review describes the current state of knowledge about the nature of chromatin at telomeres, its functions, and the relation between chromatin structure and TERRA. BACKGROUND Faculty job satisfaction (or dissatisfaction) is reported in the literature, and many surveys designed to measure satisfaction exist in higher education fields. However, measuring satisfaction does not inherently change satisfaction. Change must be agreed upon by faculty and administration if it is to be successful. OBJECTIVES The aim of this study is to describe a qualitative, iterative approach to drive consensus, promote change, and address pharmacy faculty job satisfaction using a modified Delphi Technique embedded in Lewin's Change Management Model, and to identify the top three faculty priorities to improve their job satisfaction as an exemplar of the approach. selleck inhibitor METHODS Using the modified Delphi Technique embedded in Lewin's Change Management Model, faculty in a private pharmacy school were anonymously asked to respond to questions about priorities that would most improve their job satisfaction. Answers were divided into themes, and themes and responses were sent back to faculty to anonymously rank in order of importance. Two priorities for the College were established. However, a tie breaker necessitated a third round (modified from traditional Delphi) where faculty discussed and voted on the third priority. RESULTS Survey response rates were 78% and 82.9% for Round One and Round Two. Round One responses (91) were divided into 13 themes for faculty to rank for Round Two. Round Three established the third faculty priority. Priorities for job satisfaction included workload evaluation, recruitment, and faculty development. CONCLUSION The Delphi Technique embedded into Lewin's Model of Change Management successfully guided administration toward new priorities at the College level directed at improving faculty job satisfaction. BACKGROUND Klebsiella pneumonia is commonly isolated after lung transplantation. We observed an increase in bronchial complications following an outbreak of Klebsiella pneumoniae carbapenemase-producing Klebsiella (KPC-KP). METHODS The study enrolled 173 patients, who had undergone bilateral lung transplantation between 2012 and 2018, to examine the association between bronchial complications following lung transplantation, and KPC-KP. The KPC-KP group was defined as patients in whom isolates from sputum or bronchoalveolar lavage (BAL) fluid were positive for KPC-KP. The presence of bronchial complications was defined as a positive finding on bronchoscopy in accordance with the criteria of the International Society for Heart and Lung Transplantation. Risk factors for bronchial complications were analyzed. RESULTS KPC-KP was identified in 29 patients (16.8%), and bronchial dehiscence was observed in 13 patients (7.5%). Smoking [odds ratio (OR) 5.690, 95% confidence interval (CI) 1.106-29.260, P=0.037], presence of KPC-KP (OR 5.360, 95% CI 1.380-20.810, P=0.015), and bronchial necrosis (OR 7.009, 95% CI 1.811-27.124, P=0.005) were associated with bronchial dehiscence in a multivariate logistic regression model. CONCLUSIONS The presence of KPC-KP in lung-transplant recipients significantly increased the risk of bronchial dehiscence, independent of bronchial necrosis. Thus, patients with KPC-KP require greater surveillance and follow-up bronchoscopy, irrespective of the presence or absence of bronchial necrosis or the overall patient condition. We report a case of a 23-day-old girl who presented with repeated life-threatening myocardial ischemia from intermittent aortic insufficiency due to fixation of the left coronary cusp against the aortic wall. The patient underwent aortic valve repair with partial commissuroplasty of the left-right and left-non commissures. Following the surgical intervention, the patient has been well, with no ischemic event for over 1 year. This diagnosis should be considered as a differential diagnosis in pediatric cases with myocardial ischemia. Although myocardial ischemia in early infancy is rare, it is potentially life threatening. Early diagnosis is pivotal to prevent irreversible cardiac dysfunction and/or death. The causes of myocardial ischemia include coronary arterial lesions, coronary ostial lesions, and embolisms (1, 2). Diagnosing the cause of myocardial ischemia is integral to the planning of a precise treatment strategy. Here, we report an extremely rare case of a 23-day-old girl with life-threatening myocardial ischemia due to intermittent aortic insufficiency (AI). BACKGROUND The effect of intraoperative fluid balance on postoperative acute kidney injury (AKI) in cardiac surgical patients is poorly defined. METHODS Retrospective study of patients undergoing aortic valve replacement (AVR) for aortic stenosis. The primary outcome of interest was postoperative AKI. Secondary outcomes included postoperative fluid balance, cardiac index, vasopressor use, hospital free days, stroke, myocardial infarction (MI), hospital readmission, 30- and 90-day mortality. RESULTS 2327 patients were analyzed. Positive intraoperative fluid balance was associated with lower odds of AKI - lowest odds 20-39 mL/kg group [OR=0.56, 95% CI (0.38, 0.81); p=0.002]. Positive intraoperative fluid balance was associated with lower postoperative fluid balance. Increased ultrafiltration volume was associated with increased postoperative fluid resuscitation and vasopressor use. AKI was associated with increased 30- and 90-day mortality. Increased fluid balance was associated with increased odds of MI and 30-day mortality. Increased ultrafiltration volume was associated with increased odds of 30- and 90-day mortality. CONCLUSIONS In patients who underwent AVR for aortic stenosis, positive intraoperative fluid balance was associated with decreased odds of AKI. Patients developing AKI had increased 30- and 90-day mortality. While the overall incidence was low, increased intraoperative fluid balance was associated with MI and 30-day mortality, while increased ultrafiltration volume was associated with 30- and 90-day morality. Prospective studies are needed to better define proper intraoperative fluid management in patients undergoing cardiac surgery.
