The effect of an organ procurement experience on preclinical medical student perceptions of transplant surgery.

Transplant surgery is a predominantly male specialty with high burnout rates. There are currently limited data regarding how programs can attract a diverse applicant pool to the field of transplant surgery. This study evaluated the effect of an Organ Procurement Experience elective on preclinical medical students' perceptions of transplant surgery in a prospective, longitudinal study. Preclinical medical students were anonymously surveyed before and after attending a deceased donor organ procurement. Questions focused on the following themes: Personal Beliefs, Personal/Professional Life, Diversity, and Gender Equality. Responses were rated on a five-point Likert scale. Ninety-nine and 45 students completed pre/post-procurement survey, respectively. Post-procurement responses demonstrated increased education about the field (2.1/5 vs 3.89/5, P < 0.001) and perceptions of the personalities and collegiality between surgeons (3.06/5 vs 3.73/5, P = 0.005). Post-procurement, women were less likely to feel that female transplant surgeons are treated differently (3.98/5 vs. 3.45/5, P < 0.017). Post-procurement, 19% agreed that transplant surgeons have a high quality of life. One percent of respondents felt the current gender distribution in transplant surgery is satisfactory. The Organ Procurement Experience significantly improved preclinical students' perceptions of the field. However, there remains a strong concern about quality of life and gender diversity within the field.

Adeno-associated virus vectors and neurological gene therapy.

Gene therapy has strong potential for treating a variety of genetic disorders, as demonstrated in recent clinical trials. There is unfortunately no scarcity of disease targets, and the grand challenge in this field has instead been the development of safe and efficient gene delivery platforms. To date, approximately two thirds of the 1800 gene therapy clinical trials completed worldwide have used viral vectors. Among these, adeno-associated virus (AAV) has emerged as particularly promising because of its impressive safety profile and efficiency in transducing a wide range of cell types. Gene delivery to the CNS involves both considerable promise and unique challenges, and better AAV vectors are thus needed to translate CNS gene therapy approaches to the clinic. This review discusses strategies for vector design, potential routes of administration, immune responses, and clinical applications of AAV in the CNS.
