ABSTRACT
Burnout is a widespread issue among physicians, including radiologists and radiology trainees. Long hours, isolation, and substantial stress levels contribute to healthcare workers experiencing a substantially higher rate of burnout compared with other professionals. Resident physicians, continuously exposed to stressors such as new clinical situations and performance feedback, are particularly susceptible. Mentorship has proven to be an effective strategy in mitigating burnout. Various mentorship delivery models exist, all aiming to have mentors serve as role models to mentees, thereby alleviating stress and anxiety. Physician groups and healthcare enterprises have actively implemented these programs, recognizing them as both successful and cost-effective. This article explores different mentorship models, their implementation processes, and the effectiveness of these programs as a standard component of academic departments.
ABSTRACT
Despite being rarely discussed, perinephric lymphatics are involved in many pathological and benign processes. The lymphatic system in the kidneys has a harmonious dynamic with ureteral and venous outflow, which can result in pathology when this dynamic is disturbed. Although limited by the small size of lymphatics, multiple established and emerging imaging techniques are available to visualize perinephric lymphatics. Manifestations of perirenal pathology may be in the form of dilation of perirenal lymphatics, as with peripelvic cysts and lymphangiectasia. Lymphatic collections may also occur, either congenital or as a sequela of renal surgery or transplantation. The perirenal lymphatics are also intimately involved in lymphoproliferative disorders, such as lymphoma as well as the malignant spread of disease. Although these pathologic entities often have overlapping imaging features, some have distinguishing characteristics that can suggest the diagnosis when paired with the clinical history.

Shunts are commonly employed to treat hydrocephalus, a severe central nervous disease caused by the buildup of cerebrospinal fluid in the brain. These shunts divert excessive cerebrospinal fluid from brain ventricles to other body cavities, thereby relieving the symptoms. However, these shunts are highly prone to failure due to obstruction from cellular debris, leading to cerebrospinal fluid accumulation in the brain and exacerbation of neurological symptoms. Therefore, there is a clinical need for a reliable, non-invasive method of monitoring shunt performance. Recently, a simple inline flow sensor was reported for monitoring ventriculoperitoneal shunting of cerebrospinal fluid in hydrocephalus treatment. The present work aimed to evaluate performance of the device in an animal model of hydrocephalus. Sensor-equipped shunt tubes were placed in anesthetized, juvenile swine. The flows reported by the sensor were compared with gravimetric flow measurements. Robust correlations (râ¯≈â¯0.87-0.96) between the gravimetric and sensor-reported flows were obtained in 4 of the 6 experiments. The mean slope of the linear relationship of the gravimetrically determined vs. sensor flow rates was 0.98 ± 0.09 in the 6 experiments, indicating the sensor accurately reported shunt flows up to 35â¯ml/h. The sensor responded immediately to abrupt flow changes following cerebroventricular fluid injections. Minor hardware problems were identified and corrected. These experiments provide practical guidance for future preclinical testing of the device.
