Implementation evaluation of a medical student-led intervention to enhance students' engagement with research: Findings and lessons learned.

INTRODUCTION: Medical colleges globally have student organizations that serve to enable students' involvement in research. However, details of their approach and activities are seldom published to serve as learning for student organizations in other settings. The Student Research Forum (SRF), a student organization based at a private medical school in Pakistan aims to facilitate students in acquiring research skills. Following the observation of a downward trajectory of student initiative and interest, SRF leadership restructured the organization and improve its impact. This study describes the development and implementation evaluation of the interventions. METHODOLOGY: The operational framework was revised using the Theory of Change by the core group. Major interventions included enhanced social media and outreach coordination, research workshops, journal clubs, and mentorship to increase research output, mentorship opportunities, and knowledge of medical research; ultimately improving quality in research. The outcomes generated over the course of the study's duration from July 2019 to September 2021 were analyzed using the process metrics of reach, adoption, and efficacy. RESULTS: As a result of the interventions, SRF expanded its reach by conducting a total of 41 events during the duration of the study, facilitated by social media growth on each of SRF's online platforms, with a 300% increase in followers on Facebook, and a nationwide network of 91 student ambassadors. An annual workshop series taught research skills to more than 3800 participants. Students leading their own events, SRF featuring international speakers, and the abstracts submitted to SRF's annual conference, along with the conference's reach of 10,000 students, are seen as improvements in the ToC-informed interventions' adoption. The efficacy of the interventions manifested as the REACH program allocated 56 research projects to vetted applicants. CONCLUSION: The applied interventions have accelerated SRF's progress towards achieving its long-term outcome of increased quality in research as translated by increased research output quantity, mentorship, and knowledge of medical research. Further evaluation is required to assess the success of the ToC. As SRF continues to grow, a continued analysis of the implementation outcomes is imperative to gauge its effectiveness.

Severe mitral regurgitation in nonagenarians: Impact of symptomatic status, frailty and etiology on management and outcomes.

BACKGROUND: Data regarding mitral regurgitation (MR) in extremely elderly patients are limited. The aim of the present study was to assess symptomatic status, frailty, etiology and outcomes for nonagenarians with severe MR. METHODS: Single-center cohort study of patients ≥90 years of age with at least 3+ MR on echocardiography between September 2010 and August 2018. Out of a total of 11,998 patients with at least 3+ MR, 267 patients were included in the present study. RESULTS: The average age was 93.5 ± 2.6 years, and 57% were female. At baseline, 88% were symptomatic, with mean Charlson co-morbidity index of 6 ± 2 points, and mean frailty score of 2.9 ± 1.4 points. Primary MR was present in 50%, secondary in 47%, and prosthetic valve dysfunction in 3%. Among patients with primary MR, the most common etiology was mitral annular calcification (58%). In comparison, the most common etiology of secondary MR was atrial functional MR (52%). Of all, 95% were treated conservatively, and 5% underwent interventional management. Among 253 patients who had follow-up data with a median follow-up of 14 months (25th-75th interquartile range: 3-31 months), 191 patients (75%) died. Mortality trended higher in the conservative group versus the interventional group (60% vs. 22%, log-rank P = 0.063). CONCLUSIONS: Most nonagenarians with significant MR were symptomatic at presentation, had elevated Charlson co-morbidity index and frailty scores. Etiologies of MR were almost equally distributed between primary and secondary causes. The vast majority of nonagenarians with significant MR were conservatively managed.

Cardiovascular Safety Reporting in Contemporary Breast Cancer Clinical Trials.

Background Several cancer therapies have been associated with cardiovascular harm in early-phase clinical trials. However, some cardiovascular harms do not manifest until later-phase trials. To limit interdisease variability, we focused on breast cancer. Thus, we assessed the reporting of cardiovascular safety monitoring and outcomes in phase 2 and 3 contemporary breast cancer clinical trials. Methods and Results We searched Embase and Medline records for phase 2 and 3 breast cancer pharmacotherapy trials. We examined exclusion criterion as a result of cardiovascular conditions, adverse cardiovascular event reporting, and cardiovascular safety assessment through cardiovascular imaging, ECG, troponin, or natriuretic peptides. Fisher's exact test was utilized to compare reporting. Fifty clinical trials were included in our study. Patients were excluded because of cardiovascular conditions in 42 (84%) trials. Heart failure was a frequent exclusion criterion (n=31; 62% trials). Adverse cardiovascular events were reported in 43 (86%) trials. Cardiovascular safety assessments were not reported in 23 (46%) trials, whereas natriuretic peptide and troponin assessments were not reported in any trial. Cardiovascular safety assessments were more frequently reported in industry-funded trials (69.2% versus 0.0%; P<0.001), and in trials administering targeted/immunotherapy agents compared with only hormonal/conventional chemotherapy (78.6% versus 22.7%, P<0.001). Conclusions Our findings demonstrate significant under-representation of patients with cardiovascular conditions or prevalent cardiovascular disease in contemporary later-phase breast cancer trials. Additionally, cardiovascular safety is not routinely monitored in these trials. Therefore, contemporary breast cancer clinical trials may possibly underestimate the cardiovascular risks of cancer pharmacotherapy agents for use in clinical practice.

Bilateral Psoas Abscess After Extracorporeal Shock Wave Lithotripsy: Reminder Of A Rare Complication.

Extracorporeal shock wave lithotripsy (ESWL) is among the most widely used modalities for treatment of urolithiasis since its introduction in the 1980s. The non-invasive technique reduces the risk of post-procedure complications and produces excellent stone free rates. However, complications may still follow and albeit rare, there are reports in literature of abscess formation post ESWL. Herein, we report the case of a young, immunocompetent gentleman who developed bilateral psoas abscess after undergoing this procedure. He was successfully managed at our institute with intravenous antibiotics, percutaneous abscess drainage and was discharged on day 5 post-intervention in a stable condition. There have been two similar cases reported in literature.

A species dependent response to the pro-epileptic drug pentylentetrazole in birds.

Epilepsy is common disorder that affects over 50 million people worldwide. Birds remain a promising yet largely under-explored model of epilepsy. This study reports the comparison of the response of two species of birds, Australian Parrots (APs) and Sparrows (SPs), to a pro-epileptic drug, Pentylenetetrazole (PTZ). PTZ injections caused myoclonic jerks (MCJs) and tonic clonic seizures (TCSs) in both species. The frequency of MCJs in APs was greater at the dose of 75mg/kg compared to both 50mg/kg and 25mg/kg while it was not significantly different in SPs. The comparison of APs and SPs showed that the frequency of MCJs was greater in APs compared to SPs at 25mg/kg and 75mg/kg while its latency was reduced at 25mg/kg and 50mg/kg. Interestingly SPs had a reduced latency of TCSs compared to APs at 75mg/kg. Glutamatergic and Gabaergic cell count was conducted to determine an association with the epileptic response to PTZ. The Glutamatergic cell counts for SPs was significantly greater than APs and conversely the Gabaergic cell counts in APs was higher compared to SPs. The reason for this difference in findings needs to be further investigated. This study shows that birds, and APs and SPs in particular, are a valid, interesting and under-explored model of epilepsy that should be further explored in order to understand the mysteries of epilepsy.
