Beyond Gender and Race: The Representation of Concealable Identities Among College Science Instructors at Research Institutions.

Concealable stigmatized identities (CSIs) are identities that can be kept hidden and carry negative stereotypes. To understand the potential influence instructors have as role models, we must first explore the identities instructors have and whether they disclose those identities to undergraduates. We surveyed national samples of science instructors (n = 1248) and undergraduates (n = 2428) at research institutions to assess the extent to which instructors hold CSIs, whether they reveal those identities to undergraduates, how the prevalence of CSIs among instructors compares to their prevalence among undergraduates, and the reasons instructors reveal or conceal their CSIs. The most common CSIs instructors reported were having anxiety (35%) and being a first-generation college student (29%). Relatively few instructors revealed CSIs to students. The largest mismatches of CSI prevalence were for struggling academically in college (-30%) and having anxiety (-25%); all mismatches grew when accounting for instructor CSI disclosure, highlighting that students perceive fewer role models of scientists with CSIs than actually exist.

The Aspects of Active-Learning Science Courses That Exacerbate and Alleviate Depression in Undergraduates.

College science courses continue to transition from traditional lecture to active learning, which has been shown to have both alleviating and exacerbating effects on undergraduate mental health. Notably, existing studies have primarily examined the relationship between active learning and anxiety, and no studies have specifically assessed the relationship between active learning and depression. To address this gap, we conducted hourlong exploratory interviews with 29 undergraduates from six institutions who identify as having depression and who had been enrolled in at least one active-learning college science course. We probed how undergraduates' depression affects their experiences in active learning, and in turn, what aspects of active-learning practices exacerbate or alleviate students' depressive symptoms. Students described that their depression negatively impacted their cognitive domains, which could make learning and social interactions challenging. Additionally, we found that the underlying aspects of active-learning practices that impact students' depression fall into four overarching categories: opportunities to compare oneself with others, socializing with others while learning, frequent formative evaluation, and engagement in learning. Each of these aspects of active learning could alleviate and/or exacerbate depressive symptoms. This work supports recommendations to create more inclusive active-learning courses for students with depression.

The Clinical Impact of Image Guidance and Robotics in Spinal Surgery: A Review of Safety, Accuracy, Efficiency, and Complication Reduction.

Image guidance (IG) and robotic-assisted (RA) surgery are modern technological advancements that have provided novel ways to perform precise and accurate spinal surgery. These innovations supply real-time, three-dimensional imaging information to aid in instrumentation, decompression, and implant placement. Although nothing can replace the knowledge and expertise of an experienced spine surgeon, these platforms do have the potential to supplement the individual surgeon's capabilities. Specific advantages include more precise pedicle screw placement, minimally invasive surgery with less reliance on intraoperative fluoroscopy, and lower radiation exposure to the surgeon and staff. As these technologies have become more widely adopted over the years, novel uses such as tumor resection have been explored. Disadvantages include the cost of implementing IG and robotics platforms, the initial learning curve for both the surgeon and the staff, and increased patient radiation exposure in scoliosis surgery. Also, given the relatively recent transition of many procedures from inpatient settings to ambulatory surgery centers, access to current devices may be cost prohibitive and not as readily available at some centers. Regarding patient-related outcomes, much further research is warranted. The short-term benefits of minimally invasive surgery often bolster the perioperative and early postoperative outcomes in many retrospective studies on IG and RA surgery. Randomized controlled trials limiting such confounding factors are warranted to definitively show potential independent improvements in patient-related outcomes specifically attributable to IG and RA alone. Nonetheless, irrespective of these current unknowns, it is clear that these technologies have changed the field and the practice of spine surgery. Surgeons should be familiar with the potential benefits and tradeoffs of these platforms when considering adopting IG and robotics in their practices.
