Teaching Sideways: Implementing a Peer-Led Medical Student Orientation Bootcamp and Survival Guide for Internal Medicine Clerkship.

OBJECTIVES: Transitioning from classroom learning to clerkships presents a challenge for medical students because there is often sparse preparation material on how to effectively contribute to the medical team as a clerkship student. Although some medical schools have implemented transition-to-clerkship sessions, they often are led by faculty and lack the practical and contemporary guidance from students who have recently completed clerkships themselves. METHODS: Using a sideways mentorship approach, we implemented a 1-hour near-peer Internal Medicine (IM) clerkship orientation bootcamp at our medical school and wrote an accompanying survival guide to teach students how to function as part of a medical team and to increase the transparency of student expectations and evaluations during the clerkship. The 1-hour session covered the following core topics: clerkship logistics, how to gather/present clinical information, a resident/student question-and-answer panel, and how to contribute to the medical team. A postclerkship medical student and second-year IM resident conducted the bootcamp for four student cohorts (105 students total) during the January to December 2022 clerkship year before the IM rotation of each cohort. After the bootcamp, students received a copy of the survival guide to solidify concepts covered in the session. RESULTS: A preclerkship survey included questions to assess student confidence in 10 core IM clerkship domains pre- and postbootcamp. Both pre- and postclerkship surveys asked students to provide feedback on bootcamp strengths and weaknesses. Wilcoxon signed rank tests revealed a significant increase in postbootcamp student confidence rating for all 10 clerkship domains in the early clerkship cohort and in the late clerkship cohort for all of the domains, except finding clinical reference resources (P = 0.15). The bootcamp had the largest effect size (r) on student confidence in both early and late clerkship cohorts for the following clerkship domains: familiarity with IM clerkship evaluation (early: r = 0.61, P < 0.001; late: r = 0.56, P = 0.002), identification of ways to contribute to the medical team (early: r = 0.58, P < 0.001; late: r = 0.63, P < 0.001), and prerounding/chart checking (early r = 0.52, P < 0.001; late: r = 0.55, P = 0.001). The percentage of students rating the helpfulness of both the bootcamp and survival guide as a 3 to 5 on a 5-point Likert scale in the postclerkship survey was highest for the following domains: being familiar with the structure of a subjective, objective, assessment, and plan presentation (88% and 97%), prerounding/chart checking (82% and 95%), writing progress notes (82% and 92%), and identifying ways to contribute to the medical team (82% and 95%). Students commented that the main strengths of the bootcamp included its specific tips on synthesizing and presenting clinical information and its transparency about student expectations and experiences. CONCLUSIONS: A structured student-led bootcamp can increase clerkship preparation in core domains. The bootcamp is now part of mandatory clerkship didactics at our medical school, given its success during the 2022 clerkship year, and its content is continuing to be expanded upon by postclerkship students and residents. In addition, the format of the bootcamp also is being adapted to other clerkships, including surgery and obstetrics/gynecology.

Impact of GH administration on skeletal endpoints in adults with overweight/obesity.

Objective: Overweight/obesity is associated with relative growth hormone (GH) deficiency and increased fracture risk. We hypothesized that GH administration would improve bone endpoints in individuals with overweight/obesity. Design: An 18-month, randomized, double-blind, placebo-controlled study of GH, followed by 6-month observation. Methods: In this study, 77 adults (53% men), aged 18-65 years, BMI ≥ 25 kg/m2, and BMD T- or Z-score ≤ -1.0 were randomized to daily subcutaneous GH or placebo, targeting IGF1 in the upper quartile of the age-appropriate normal range. Forty-nine completed 18 months. DXA, volumetric quantitative CT, and high-resolution peripheral quantitative CT were performed. Results: Pre-treatment mean age (48 ± 12 years), BMI (33.1 ± 5.7 kg/m2), and BMD were similar between groups. P1NP, osteocalcin, and CTX increased (P < 0.005) and visceral adipose tissue decreased (P = 0.04) at 18 months in the GH vs placebo group. Hip and radius aBMD, spine and tibial vBMD, tibial cortical thickness, and radial and tibial failure load decreased in the GH vs placebo group (P < 0.05). Between 18 and 24 months (post-treatment observation period), radius aBMD and tibia cortical thickness increased in the GH vs placebo group. At 24 months, there were no differences between the GH and placebo groups in bone density, structure, or strength compared to baseline. Conclusions: GH administration for 18 months increased bone turnover in adults with overweight/obesity. It also decreased some measures of BMD, bone microarchitecture, and bone strength, which all returned to pre-treatment levels 6 months post-therapy. Whether GH administration increases BMD with longer treatment duration, or after mineralization of an expanded remodeling space post-treatment, requires further investigation.

Field experimental evidence shows that self-interest attracts more sunlight.

This study examines how messaging approaches in a prosocial intervention can influence not only the effectiveness of the intervention but also, contagion afterward. Our investigation focuses on leveraging two motivations for solar adoption: self-interest and prosocial. Using data from a natural field experiment in 29 municipalities containing 684,000 people, we find that self-interest messaging is twice as effective in inducing solar adoption both during and after the intervention. Adoptions under self-interest messaging have 10% higher net present value, but prosocial messaging increases the likelihood that adopters recommend solar to their friends and neighbors. Income moderates the effectiveness of self-interest messaging, performing much better in high-income communities than low- and moderate-income communities. There was no significant difference across income groups for prosocial messaging. These results provide guidance to policy makers aiming to encourage prosocial behavior across all income groups.

Credibility-enhancing displays promote the provision of non-normative public goods.

Promoting the adoption of public goods that are not yet widely accepted is particularly challenging. This is because most tools for increasing cooperation-such as reputation concerns1 and information about social norms2-are typically effective only for behaviours that are commonly practiced, or at least generally agreed upon as being desirable. Here we examine how advocates can successfully promote non-normative (that is, rare or unpopular) public goods. We do so by applying the cultural evolutionary theory of credibility-enhancing displays3, which argues that beliefs are spread more effectively by actions than by words alone-because actions provide information about the actor's true beliefs. Based on this logic, people who themselves engage in a given behaviour will be more effective advocates for that behaviour than people who merely extol its virtues-specifically because engaging in a behaviour credibly signals a belief in its value. As predicted, a field study of a programme that promotes residential solar panel installation in 58 towns in the United States-comprising 1.4 million residents in total-found that community organizers who themselves installed through the programme recruited 62.8% more residents to install solar panels than community organizers who did not. This effect was replicated in three pre-registered randomized survey experiments (total n = 1,805). These experiments also support the theoretical prediction that this effect is specifically driven by subjects' beliefs about what the community organizer believes about solar panels (that is, second-order beliefs), and demonstrate generalizability to four other highly non-normative behaviours. Our findings shed light on how to spread non-normative prosocial behaviours, offer an empirical demonstration of credibility-enhancing displays and have substantial implications for practitioners and policy-makers.

Consumers' Response to an On-Shelf Nutrition Labelling System in Supermarkets: Evidence to Inform Policy and Practice.

Policy Points: On-shelf nutrition labelling systems in supermarkets, such as the Guiding Stars system, are intended to provide consumers with simple, standardized nutrition information to support more informed and healthier food choices. Policies that support the provision of simplified nutrition labelling systems may encourage consumers to make positive shifts in food-purchasing behaviors. The shifts in consumer food-purchasing patterns observed in our study after the introduction of the Guiding Stars system in supermarkets translated into measurable nutritional benefits, including more items purchased with slightly less trans fat and sugar and more fiber and omega-3 fatty acids. This study is one of the first to report the positive impact of an on-shelf nutrition labelling system on supermarket sales and revenues-key information that was specifically requested by the US National Academies, as such labelling interventions may be more sustainable if they lead to higher revenues. CONTEXT: Providing a nutrition rating system on the front of food packages or on retail shelf tags has been proposed as a policy strategy for supporting healthier food choices. Guiding Stars is an on-shelf nutrition labelling system that scores foods in a supermarket based on nutritional quality; scores are then translated into ratings of 0 to 3 stars. It is consistent with evidence-informed recommendations for well-designed labels, except for not labelling 0-star products. The largest supermarket retailer in Canada rolled out the Guiding Stars system in supermarkets across Ontario, Canada. The aim of our study was to examine the extent to which consumers respond to an on-shelf nutrition labelling system in supermarkets to inform current and future nutrition labelling policies and practices. METHODS: Capitalizing on a natural experiment, we conducted a quasi-experimental study across 3 supermarket banners (or "chains") in Ontario, one of which implemented the Guiding Stars system in 2012. We used aggregated supermarket transaction data to test the effect of Guiding Stars on the nutritional quality of food purchases in intervention supermarkets relative to control supermarkets. We also conducted exit surveys among 783 randomly selected shoppers from intervention and control supermarkets to assess consumer awareness, understanding, trust, and self-reported use of the labelling system. FINDINGS: Relative to control supermarkets, shoppers in intervention supermarkets made small but significant shifts toward purchasing foods with higher nutritional ratings; however, shifts varied in direction and magnitude across food categories. These shifts translated into foods being purchased with slightly less trans fat and sugar and more fiber and omega-3 fatty acids. We also found increases in the number of products per transaction, price per product purchased, and total revenues. Results of the exit surveys indicate a modest proportion of consumers were aware of, understood, and trusted Guiding Stars in intervention supermarkets, and a small proportion of consumers reported using this system when making purchasing decisions. However, 47% of shoppers exposed to Guiding Stars were confused when asked to interpret the meaning of a 0-star product that does not display a rating on the shelf tag. CONCLUSIONS: This study demonstrates support for policies promoting on-shelf nutrition labels designed according to evidence-informed principles, but policymakers should move forward with caution when investing in such systems until research has confirmed optimal label design, clarified the mechanisms through which dietary intake is improved, and assessed associations with nutrition-related health outcomes.
