©RSNA, 2020.Atherosclerotic cardiovascular disease (ASCVD) is the main cause of morbidity and mortality in the US. ASCVD is caused by elevated levels of ApoB lipoproteins, which over many years penetrate the arterial subendothelial space leading to plaque growth and eventually rupture causing clinical symptoms. ApoB lipoprotein levels are approximated in clinical practice by LDL-C measurement. LDL-C lowering agents (statins, ezetimibe and PCSK9 inhibitors) reduce cardiovascular risk in primary and secondary prevention proportionally to LDL-C reduction (23% per 1 mmol/L of LDL). However, for a variety of reasons, many patients do not achieve their recommended LDL-C levels using currently available therapies. This has prompted the development of new LDL-C lowering drugs in the hope to reduce cardiovascular risk, such as bempedoic acid, inclisiran, gemcabene and evinacumab. Drugs targeting other lipids (triglycerides, HDL-C, lipoprotein (a)), intravascular inflammation or acting by other mechanisms also have a role in atherosclerosis prevention, however, they will not be covered in this review.Cardiac arrest in Wolff-Parkinson-White (WPW) is a rare event, and although some patients appear to be at greater risk, there is no consensus on clear risk factors. We present a case of a 23-year-old male patient, with a known history of WPW pattern, who suffered an out of hospital ventricular fibrillation after the consumption of rather small dose of (meth)amphetamines. The use of illegal drug can predispose WPW patients to fatal arrhythmia and cardiac arrest. Patients with WPW pattern should be well informed about the risks of (meth)amphetamines and some might be considered for medical therapy or catheter ablation.PURPOSE To develop recommendations for management of patients with breast cancer (BC) with germline mutations in BC susceptibility genes. METHODS The American Society of Clinical Oncology, American Society for Radiation Oncology, and Society of Surgical Oncology convened an Expert Panel to develop recommendations based on a systematic review of the literature and a formal consensus process. RESULTS Fifty-eight articles met eligibility criteria and formed the evidentiary basis for the local therapy recommendations; six randomized controlled trials of systemic therapy met eligibility criteria. RECOMMENDATIONS Patients with newly diagnosed BC and BRCA1/2 mutations may be considered for breast-conserving therapy (BCT), with local control of the index cancer similar to that of noncarriers. The significant risk of a contralateral BC (CBC), especially in young women, and the higher risk of new cancers in the ipsilateral breast warrant discussion of bilateral mastectomy. Patients with mutations in moderate-risk genesional information available at www.asco.org/breast-cancer-guidelines.Purpose To investigate the influence of changes in α/β ratio (range 1.5-3 Gy) on iso-effective doses, with varying treatment time, in spinal cord and central nervous system tissues with comparable radio-sensitivity. It is important to establish if an α/β ratio of 2 Gy, the accepted norm for neuro-oncology iso-effect estimations, can be used.Methods The rat spinal cord irradiation data of Pop et al (2000) provided ED50 values for radiation myelopathy for treatment times that varied from minutes to ∼6 days. Analysis using biphasic repair kinetics, allowing for variable dose-rates, provided the best fit with repair half-times of 0.19 and 2.16 hr, each providing ∼50% of overall repair; with an α/β ratio 2.47 Gy (CI 1.5- 3.95 Gy). Using the above data set, graphical methods were used to investigate changes in the repair parameters for differing fixed α/β ratios between 1.5 and 3.0 Gy. Two different intermittent dose delivery equations were used to evaluate the implications in a radiosurgery setting.Results Changes calculations using the originally proposed α/β ratio of 2.47 Gy are still appropriate. For calculations involving a combination of radio-surgery and other modalities, such as fractionated radiotherapy, it would be appropriate in all cases to apply a value of 2 Gy, the accepted norm in neuro-oncology, without significant loss of accuracy in the radio-surgical component. This may have important applications in retreatment situations.Peer evaluation skills are not typically taught to students, yet they are expected to provide high-quality feedback to their peers. Gameful learning, a pedagogy supporting student-driven learning, can further reinforce the development of peer evaluation skills, if students are motivated to improve upon them. To better understand the effects of a peer evaluation training on the quality of student-generated peer evaluations, we scored peer evaluations from two cohorts taking a graduate-level nutritional sciences class using gameful learning pedagogy. The intervention group completed a peer evaluation training before engaging in peer reviews, while the control group did not. The training included two readings, a video, and reflection questions. The peer evaluations submitted by both the intervention and control groups were assessed on a validated rubric. The peer evaluation training had a positive effect on the quality of the submitted peer evaluations. The intervention group had a 10.8% higher score on its first submitted peer evaluation compared with controls (P = 0.003). The intervention group improved the quality of its future submissions by a further 8.9%, whereas the controls did not continue to improve substantially (P less then 0.001). Overall, peer review training enhanced the quality of peer evaluations and allowed students to develop professional skills that they can utilize in any biomedical profession. Our results highlight the importance of peer evaluation training in combination with repeated practice and student-driven learning brought forth by gameful learning pedagogy in improving the quality of evaluations and developing professional skills.Many medical schools offer pre-professional programs to undergraduate students. 5-Triiodo-L-thyronine The main purpose of the university pre-professional program (UPPP) is to equip students with the necessary knowledge and skills required to successfully cope with the academic demands of further education provided by professional colleges. The aim of this commentary article is to describe the role of UPPP at King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in preparing students to continue studies at the College of Medicine (COM) and other health-related colleges. The anatomy and physiology course is presented as a representative model. An outline of the UPPP in the context of the curriculum, teaching strategies, learning facilities, and assessment is presented. The pre-professional program at KSAU-HS prepares school graduates to become self-learners and enable them to learn effectively in the clinical context in a problem-based learning curriculum at COM.Anatomy and Physiology courses taught at community colleges tend to focus laboratory hours primarily on anatomy as opposed to physiology. However, research demonstrates that, when instructors utilize active learning approaches (such as in laboratory settings) where students participate in their own learning, students have improved outcomes, such as higher test scores and better retention of material. To provide community college students with opportunities for active learning in physiology, we developed two laboratory exercises to engage students in cardiac and skeletal muscle physiology. We utilized low-cost SpikerBox devices to measure electrical activity during cardiac (electrocardiogram) and skeletal muscle (electromyogram) contraction. Laboratory activities were employed in Anatomy and Physiology courses at two community colleges in southeast Michigan. A 2-h laboratory period was structured with a 20-min slide presentation covering background material on the subject and experiments to examine the effects of environmental variables on nervous system control of cardiac and skeletal muscle contraction. Students were asked to provide hypotheses and proposed mechanisms, complete a results section, and provide conclusions for the experiments based on their results. link2 Our laboratory exercises improved student learning in physiology and knowledge of the scientific method and were well-received by community college students enrolled in Anatomy and Physiology. Our results demonstrate that the use of a SpikerBox for cardiac and skeletal muscle physiology concepts is a low-cost and effective approach to integrate physiology activities into an Anatomy and Physiology course.Generating an increasingly skilled and numerous workforces of science, technology, engineering, and mathematics (STEM) professionals is a national priority. Central to this goal is improving the ability of STEM graduates to apply scientific inquiry within oral communication, a necessary skill for STEM professionals. In this case study of an introductory biology course, we observed that providing explanatory feedback to students responding to inquiry-based questions in an oral examination suggests improvements in students' abilities to critically analyze results, draw conclusions, and discuss the broader implications of data. We found students struggled with generating hypotheses and constraining discussions of scientific limitation and broader implications. We show that low-performing students especially benefit from the feedback intervention. The findings of this study are applicable to college and university instructors who are looking to incorporate methods for teaching students to use scientific inquiry effectively during oral communication, particularly those with access to teaching assistants.Heterogeneity in patients with colorectal cancer (CRC) leads to different strategies in clinical decision making. Identifying distinctive subgroups in patients contributes to develop more individualized treatments. This study constructed a novel prediction model for the prognosis of CRC patients based on the value of risk score combining the expression status of immune-related genes and coefficients. In this study, we built an interactive network of prognosis-related immune genes and transcription factors and adopted several methods to verify the accuracy of model. Moreover, we assessed the correlation between risk score and immune infiltration. The results suggested that the model was well fit and the risk score could be an independent predictive factor for CRC patients. This model has high application value in the clinic.Objectives To investigate the clinical course of Japanese patients with early diffuse cutaneous systemic sclerosis (dcSSc) and early SSc with interstitial lung disease (ILD).Methods We prospectively analyzed the clinical features of 207 Japanese patients with early dcSSc (n = 150) and limited cutaneous SSc (lcSSc) with ILD (n = 57) in 10 medical centers every year for 7 consecutive years.Results Mean modified Rodnan total skin thickness score (mRSS) was 18.3 and 67.4% of the cohort had ILD. Most patients started immunosuppressive therapy and vasodilators during 7 years (83.4% and 87.9%, respectively). Mean value of mRSS of total patients was significantly reduced from the initial registration after the first year. link3 However, other parameters for physical function associated with skin sclerosis including fist closure, hand extension, and oral aperture were not so ameliorated during the study period. Health Assessment Questionnaire-disability index and serum KL-6 levels were constant throughout the course. Percent vital capacity and the presence of ILD, clinically suspected pulmonary arterial hypertension, and digital ulcers were gradually exacerbated during the period.
