    During the last decade, medical schools have turned to writing exercises as a means for encouraging students to reflect on their learning experiences during clinical clerkships. The reasons for the increased popularity of reflective writing are broad. Approaches to encouraging reflective writing are quite varied. Recently, three internal medicine clerkships (University of Chicago Pritzker School of Medicine, University of Florida College of Medicine, and University of Massachusetts Medical School) independently implemented reflective writing activities in the clerkship curriculum

    Who Shares? Who Doesn't? Factors Associated with Openly Archiving Raw Research Data

    Many initiatives encourage investigators to share their raw datasets in hopes of increasing research efficiency and quality. Despite these investments of time and money, we do not have a firm grasp of who openly shares raw research data, who doesn't, and which initiatives are correlated with high rates of data sharing. In this analysis I use bibliometric methods to identify patterns in the frequency with which investigators openly archive their raw gene expression microarray datasets after study publication

    Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme-precision radial-velocity (EPRV) exoplanet detection. Several methods are designed to disentangle stellar signals from true center-of-mass shifts due to planets. The Extreme-precision Spectrograph (EXPRES) Stellar Signals Project (ESSP) presents a self-consistent comparison of 22 different methods tested on the same extreme-precision spectroscopic data from EXPRES. Methods derived new activity indicators, constructed models for mapping an indicator to the needed radial-velocity (RV) correction, or separated out shape- and shift-driven RV components. Since no ground truth is known when using real data, relative method performance is assessed using the total and nightly scatter of returned RVs and agreement between the results of different methods. Nearly all submitted methods return a lower RV rms than classic linear decorrelation, but no method is yet consistently reducing the RV rms to sub-meter-per-second levels. There is a concerning lack of agreement between the RVs returned by different methods. These results suggest that continued progress in this field necessitates increased interpretability of methods, high-cadence data to capture stellar signals at all timescales, and continued tests like the ESSP using consistent data sets with more advanced metrics for method performance. Future comparisons should make use of various well-characterized data sets—such as solar data or data with known injected planetary and/or stellar signals—to better understand method performance and whether planetary signals are preserved

    The association between adult attained height and sitting height with mortality in the European prospective investigation into cancer and nutrition (EPIC)

    Adult height and sitting height may reflect genetic and environmental factors, including early life nutrition, physical and social environments. Previous studies have reported divergent associations for height and chronic disease mortality, with positive associations observed for cancer mortality but inverse associations for circulatory disease mortality. Sitting height might be more strongly associated with insulin resistance; however, data on sitting height and mortality is sparse. Using the European Prospective Investigation into Cancer and Nutrition study, a prospective cohort of 409,748 individuals, we examined adult height and sitting height in relation to all-cause and cause-specific mortality. Height was measured in the majority of participants; sitting height was measured in ~253,000 participants. During an average of 12.5 years of follow-up, 29,810 deaths (11,931 from cancer and 7,346 from circulatory disease) were identified. Hazard ratios (HR) with 95% confidence intervals (CI) for death were calculated using multivariable Cox regression within quintiles of height. Height was positively associated with cancer mortality (men: HRQ5 vs. Q1=1.11, 95%CI=1.00-1.24; women: HRQ5 vs. Q1=1.17, 95%CI=1.07-1.28). In contrast, height was inversely associated with circulatory disease mortality (men: HRQ5 vs. Q1=0.63, 95%CI=0.56-0.71; women: HRQ5 vs. Q1=0.81, 95%CI=0.70-0.93). Although sitting height was not associated with cancer mortality, it was inversely associated with circulatory disease (men: HRQ5 vs. Q1=0.64, 95%CI=0.55-0.75; women: HRQ5 vs. Q1=0.60, 95%CI=0.49-0.74) and respiratory disease mortality (men: HRQ5 vs. Q1=0.45, 95%CI=0.28-0.71; women: HRQ5 vs. Q1=0.60, 95%CI=0.40-0.89). We observed opposing effects of height on cancer and circulatory disease mortality. Sitting height was inversely associated with circulatory disease and respiratory disease mortality

    Haem iron intake and risk of lung cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort

    Background Epidemiological studies suggest that haem iron, which is found predominantly in red meat and increases endogenous formation of carcinogenic N-nitroso compounds, may be positively associated with lung cancer. The objective was to examine the relationship between haem iron intake and lung cancer risk using detailed smoking history data and serum cotinine to control for potential confounding. Methods In the European Prospective Investigation into Cancer and Nutrition (EPIC), 416,746 individuals from 10 countries completed demographic and dietary questionnaires at recruitment. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for incident lung cancer (n = 3731) risk relative to haem iron, non-haem iron, and total dietary iron intake. A corresponding analysis was conducted among a nested subset of 800 lung cancer cases and 1489 matched controls for whom serum cotinine was available. Results Haem iron was associated with lung cancer risk, including after adjustment for details of smoking history (time since quitting, number of cigarettes per day): as a continuous variable (HR per 0.3 mg/1000 kcal 1.03, 95% CI 1.00-1.07), and in the highest versus lowest quintile (HR 1.16, 95% CI 1.02-1.32; trend across quintiles: P = 0.035). In contrast, non-haem iron intake was related inversely with lung cancer risk; however, this association attenuated after adjustment for smoking history. Additional adjustment for serum cotinine did not considerably alter the associations detected in the nested case-control subset. Conclusions Greater haem iron intake may be modestly associated with lung cancer risk.Peer reviewe

    Between Two Worlds: A Multi-Institutional Qualitative Analysis of Students’ Reflections on Joining the Medical Profession

    BACKGROUND: Recent changes in healthcare system and training mandates have altered the clinical learning environment. We incorporated reflective writing into Internal Medicine clerkships (IMcs) in multiple institutions so students could consider the impact of clerkship experiences on their personal and professional development. We analyzed student reflections to inform curricula and support learning. METHODS: We qualitatively analyzed the reflections of students at 3 US medical schools during IMcs (N = 292) to identify themes, tone, and reflective quality using an iterative approach. Chi-square tests assessed differences between these factors and across institutions. FINDINGS: Students openly described powerful experiences. Major themes focused on 4 categories: personal issues (PI), professional development (PD), relational issues (RI), and medical care (MC). Each major theme was represented at each institution, although with significant variability between institutions in many of the subcategories including student role (PI), development-as-a-physician (PD), professionalism (PD) (p \u3c 0.001). Students used positive tones to describe student role, development-as-a-physician and physician-patient relationship (PD) (p \u3c 0.01-0.001), and negative tones for quality and safety (MC) (p \u3c 0.05). Only 4% of writings coded as professionalism had a positive tone. Students employed a reporting voice in writing about clinical problem-solving, healthcare systems, and quality/safety (MC). DISCUSSION: Reflection is considered important to professional development. Our analysis suggests that students at 3 institutions reflect on similar experiences. Theme variability across institutions implies curricula should be tailored to local culture. Reflective quality analysis suggests students are better equipped to reflect on certain experiences over others, which may impact learning. Student reflections can function as a mirror for our organizations, offer institutional feedback for support and improvement, and inform curricula for learners and faculty

    Purpose: Each year military medical students participate in a separate, military match culminating with the Joint Services Graduate Medical Education Selection Board (JSGMESB). Prior studies have explored postinterview communication that occurs during the National Resident Matching Program (NRMP), but not during the JSGMESB. We examined the frequency and nature of communication during the JSGMESB and compared it with the NRMP. Methods: Cross-sectional survey study of senior students conducted at Uniformed Services University of the Health Sciences (USU) and seven civilian U.S. medical schools during March to May 2010. Respondents answered questions regarding communication with residency programs during the match. Results: Significantly fewer USU respondents communicated with programs compared with the civilian cohort (54.1% vs. 86.4%, p \u3c 0.01). Specific inquiries regarding rank order were more commonly experienced by USU respondents compared with civilians (17.5% vs. 4.8%, p = 0.02). USU respondents found postinterview communication both helpful (41.3%) and stressful (41.3%). 11.1% of USU respondents indicated that they moved a program higher on their final rank lists because of further communication with these programs. Conclusions: Postinterview communication during the JSGMESB process is less common and less stressful than that reported in the NRMP. USU respondents are more likely to be asked directly about their rank list and occasionally do change their lists. Uniform guidance mirroring the NRMP\u27s dealing with direct inquiries about rank lists could potentially improve the process. © Association of Military Surgeons of the U.S. All rights reserved
