Trevor J. Royce Kathleen T. Davenport James M. Dahle 《Practical radiation oncology》2019,9(4):231-238
PurposePhysician burnout is reported in more than one out of every 2 practicing clinicians and is just as prevalent in training physicians. Burnout severity is also associated with increasing levels of financial debt. Medical professionals are notable for their high and increasing levels of debt; despite this, financial literacy is poor among physicians, and financial education is largely absent from medical education. Radiation oncologists (ROs) are no different in this regard, with 33% of residents reporting high levels of burnout symptoms, 33% carrying >$200,000 of educational debt, and 75% reporting being unprepared to handle future financial decisions. To fill this gap, we reviewed the basic tenets of personal financial health for the early career RO.Methods and materialsThe core concept of financial independence (FI) is introduced, and we review 4 basic tenets of personal financial health for the young medical professional: debt, behavior, investment, and asset protection strategies.ResultsFI is achieved by saving until the desired quality of life can be maintained, independent of employment income. Debt strategy involves minimizing debt accrual, understanding student loans, and having a debt management plan. Behavioral strategy involves setting financial goals, calculating worth and a savings rate, budgeting, and frugal living. The basics of investing include asset allocation, diversification, rebalancing, and minimizing expenses. Finally, asset protection includes insuring against catastrophic events with disability, life, health, liability, and property insurance.ConclusionsHealthy financial practices can lead to FI and may facilitate professional and personal freedoms with the goal of mitigating burnout-associated stressors. The tenets of strong financial health for ROs in the early stages of their career include sound debt, behavioral, investment, and asset protection strategies. Furthermore, initial and continuing financial education is an overlooked but important curriculum component. ROs with their financial houses in order can devote more resources to learning and practicing good medicine while living healthy, rewarding lives. 相似文献

The oral effectiveness of 10 mg followed by 20 mg of isosorbide dinitrate in 21 patients with acute mycardial infarction was studied over a period of 13 hours. The patients were grouped according to initial left ventricular filling pressure: group I, pressure less than 20 mm Hg, and group II, pressure more than 20 mm Hg. Patients in group II had left ventricular failure. In both groups isosorbide dinitrate resulted in a significant decrease in pulmonary arterial pressure. The left ventricular filling pressure decreased in group I from 13.6 +/- 4.0 to 7.1 +/- 2.6 mm Hg (mean +/- 1 standard deviation) and in group II from 26.9 +/- 4.6 to 19.0 +/- 3.6 mm Hg (P less than 0.001). Cardiac output decreased in group I from 5.1 +/- 1.0 to 4.5 +/- 0.9 liters/min, whereas in group II it increased significantly from 3.5 +/- 0.8 to 4.1 to 0.9 liters/min (P less than 0.001). In both groups, peripheral arterial blood pressure decreased (P less than 0.60). Heart rate remained constant. Whether cardiac output increased or decreased was found to be dependent on the initial left ventricular filling pressure. In patients with an initially high value (above 20 mm Hg), the increase in cardiac output is probably due to the reduction of afterload. An additional factor may be the decrease in left ventricular filling pressure, which leads to an improved blood supply in the affected mural segments as a result of the decrease in the extravascular component of the coronary resistance. Significant changes in cardiac output and left ventricular filling pressure were achieved 3 to 5 hours after oral administration of isosorbide dinitrate. Clinical signs of failure were less pronounced. Isosorbide dinitrate is, therefore, a therapeutic agent in the treatment of left ventricular failure due to acute myocardial infarction. 相似文献

To assess the ability to detect coronary artery narrowings from computer-acquired angiograms, a panel of 4 observers independently identified and measured focal coronary narrowings from digital subtraction angiograms and compared the results to those obtained from standard 35-mm cine film angiograms. Both cine and digital angiograms were obtained sequentially using selective intracoronary artery injection of standard amounts of iodinated contrast media. Digital images were obtained at 8 frames/s with a 512 × 512 × 8-bit pixel matrix. Modifications in the imaging chain for computer acquisition included a slower pulsed radiographic mode, a progressive scan camera, and initial storage of the images on an 80-megabyte digital hard disk. Postprocessing computer algorithms were used to enhance the unsubtracted digital images; these included single-frame, mask-mode subtraction, vessel boundary edge enhancement, and 4-fold pixel magnification. In 19 patient studies, 32 arteries were reduced more than 25 % in diameter according to at least 1 of 4 observers on either the digital or cine film angiograms. There was no significant difference in the mean percent diameter narrowing for all the narrowings between the digital angiograms (53 ± 31 %) and the cineangiograms (52 ± 31 %). In addition, a 2-way analysis of variance yielded no significant difference between the amount of variability in the measurements between the cine film and the digital technique. This similar variability persisted when subsets of patients based on the degrees of stenosis were considered (e.g., only narrowings from 50 to 90% diameter reduction). Because digital acquisition permits immediate playback with image enhancement and greater ease of coronary artery quantification, digital angiography may have widespread clinical use for the detection and quantitation of coronary artery disease. 相似文献
