The delivery of medical student education has changed rapidly during the coronavirus disease 2019 (COVID-19) pandemic. Students in their pre-clinical years have transitioned to online courses and examinations. Students in their clinical years are not permitted on clinical rotations, and face uncertainties in career exploration and the residency application process. Medical students in all stages of training are volunteering and helping their communities. The future presence of COVID-19 throughout the United States is unknown, and medical students are eager to return to their training. This paper outlines current challenges in medical student education and the various responses that have been adopted. We also discuss possible future directions for students through involvement in telemedicine, outpatient clinic visits, and non-respiratory inpatient care tasks as adequate personal protective equipment, COVID-19 testing, and resources become more widely available.

Symptomatic degenerative prosthetic aortic valve stenosis during pregnancy represents a significant risk to both mother and fetus, and until recently, surgical aortic valve replacement (SAVR) during pregnancy was often the only choice for women opting to continue pregnancy. However, symptomatic severe stenosis in a pregnant woman with a degenerated full aortic root Freestyle stentless bioprosthesis (FSB) and reimplanted coronary arteries presents additional complexities that require an alternative surgical approach. In this case report, we describe the first successful transcatheter aortic valve replacement (TAVR) in SAVR for a severely stenotic degenerative FSB in a pregnant woman and subsequent delivery of a healthy infant several months later. TAVR in SAVR of a severely stenotic aortic FSB should be considered as a surgical option in symptomatic pregnant women. Short-term and long-term implications for future pregnancy should be discussed by a multidisciplinary team and with the patient. K E Y W O R D Saortic stenosis, pregnancy, TAVR in SAVR

Recently, Norovirus has been recognized as an important cause of diarrheal infection in kidney transplant recipients (KTRs). We assessed the risk factors and outcomes of Norovirus diarrheal infections (NVDI) and Clostridioides difficile infection (CDI) on graft and patient survival following kidney transplant (KT). We examined KTRs transplanted at our center between 1994 and 2014, and compared those who suffered from NVDI and CDI with patients who did not develop either infection. Each patient with NVDI or CDI was matched with five controls based on time from transplant. Of the 4941 KTs performed during the study period, there were 2112 evaluable cases: 66 NVDI cases, 286 CDI cases, and 1760 controls. Median uncensored graft survival following infection was 497.5 days for the NVDI group, 440 days for the CDI group, and 1271 days for controls. Those with CDI had significantly inferior graft survival than controls (HR 2.41; CI 2.01, 2.90; P < 0.001), and those with NVDI had a 23% lower risk of graft survival than controls (HR 1.23; CI 1.0, 1.52; P = 0.054). Diarrheal infection after KT is associated with reduced long‐term graft survival.
