OBJECTIVE The aim of this study was to provide guidance on supportive nurse manager role transition practices. BACKGROUND The nurse manager role is increasingly more complex and the workforce is increasingly less experienced. Wide variation in nurse manager role transition exists among organizations. Nurse managers are commonly hired without requisite knowledge and are expected to learn through experience. METHODS A mixed-methods approach was used to identify current and ideal organizational practices supporting the role transition of novice nurse managers. RESULTS Effective role transition of new nurse managers begins with human resource policies that encourage graduate preparation for nurse managers. A supportive transition program includes didactic education for knowledge development and coaching of novice nurse managers in the application of new knowledge to clinical practice experiences. Rigorous program evaluation is recommended for sustainability. CONCLUSION Nurse managers are the linchpins of organizations. Organizational leaders need to support their role transition for the success of the organization.The radiologic community is rapidly integrating a revolution that has not fully entered daily practice. It necessitates a close collaboration between computer scientists and radiologists to move from concepts to practical applications. read more This article reviews the current littérature on machine learning and deep neural network applications in the field of pulmonary embolism, chronic thromboembolic pulmonary hypertension, aorta, and chronic obstructive pulmonary disease.PURPOSE Myocardial extracellular volume fraction (ECV) using cardiovascular magnetic resonance (CMR) can identify diffuse lesions not detected by late gadolinium enhancement (LGE). We aimed to determine the prevalence of increased ECV and its relation to other CMR findings. MATERIALS AND METHODS Consecutive patients (n=609, age median [interquartile range] 53 [39 to 66] y, 62% male) underwent CMR at 1.5 T. Focal lesions on LGE images were noted. ECV in regions without focal LGE findings defined diffuse changes. Pronounced increases in left ventricular (LV) end-diastolic volume index and LV mass index, and pronounced decreases in LV ejection fraction were defined as >3 SD from the sex-specific mean in healthy volunteers. RESULTS Of 609 patients without amyloidosis or hypertrophic cardiomyopathy, 8% had diffusely increased ECV and 5% of all patients had diffusely increased ECV without any focal LGE findings. Multivariate analysis showed that a pronounced increase in the LV end-diastolic volume index was associated with increased ECV (P=0.001), but not LGE (P=0.52). A pronounced decrease in LV ejection fraction was associated with the presence of LGE (P less then 0.001), but not with increased ECV (P=0.41). CONCLUSIONS Eight percent of patients in this clinical cohort with known or suspected heart disease had diffusely increased ECV and 60% of these lacked focal LGE findings. LV size is independently associated with increased ECV, whereas systolic dysfunction is independently associated with LGE. This image-based clinical study demonstrates that ECV-CMR provides additional information negligibly related to the results of LGE imaging, and thereby increases the diagnostic yield of CMR.A pulmonary cyst usually refers to an air-filled space with a smooth, thin wall. Fluid-filled cystic lesions of the lungs include a range of etiologies such as true cysts, congenital malformations, infections, and benign and malignant neoplasms. With relatively little solid component, these lesions often have similar imaging appearances to one another. This article focuses on key imaging features and clinical characteristics that can be used to narrow the differential diagnosis.PURPOSE To evaluate the optical coherence tomography (OCT) imaging findings in recent onset neurosensory retinal detachments induced by central serous chorioretinopathy and to attempt to corroborate these findings with proposed anatomical correlates. METHODS Retinal detachments due to central serous chorioretinopathy of less than 3 months’ duration and the surrounding area were scanned with OCT. The imaging of the outer retinal bands was evaluated according to proposals by Cuenca et al and the IN•OCT Consensus classification. RESULTS Optical coherence tomography findings in 11 eyes (11 patients) with CSC showed that all hyperreflective bands above Band 4 were variably continuous within the outer portion of the serous detachment. We then attempted to reconcile inconsistencies in current explanations for the outer retinal bands to propose changes to the outer retinal OCT nomenclature. CONCLUSION Our patients’ OCT findings support the current standard that Band 3 is an outer retinal structure and that Band 4 represents the retinal pigment epithelium/Bruch complex. Confusion exists regarding whether the interdigitation zone extends halfway up or for the full length of the outer segments, and the hyporeflective band between Bands 3 and 4 has yet to receive an appropriate term. We therefore propose a modification to the IN•OCT Consensus classification by renaming the trilaminar hyporeflective, hyperreflective, and hyporeflective bands between Bands 2 and 4 as the outer segment-interdigitation zone complex consisting of the inner, middle, and outer segment-interdigitation zone, respectively.PURPOSE To compare the flow dynamics of beveled-tip to that of flat-tip vitreous cutters. METHOD The aspiration rates of balanced salt solution and swine vitreous were measured for 25-gauge and 27-gauge beveled-tip and flat-tip vitreous cutters. Fluorescent polymer microspheres were mixed with balanced salt solution to make the flow visible. The flow dynamics at maximal cutting rates and reflux of balanced salt solution were measured with video images of a high-speed camera. RESULTS The aspiration rates of balanced salt solution of the 25-gauge and 27-gauge beveled-tip cutters were significantly higher than that of the flat-tip cutters at 7,500 cut/min (P = 0.0001, P = 0.038, respectively). The aspiration rate of swine vitreous by the 25-gauge beveled-tip cutter was significantly higher than that of the flat-tip cutters (P = 0.006). The mean aspiration flow in front of the cutter was significantly faster for both beveled-tip than flat-tip cutters (P = 0.003, P = 0.023). The angle of the mean aspiration flow of both beveled-tip cutters was turned to the proximal side (P = 0.
