Revisiting Feed Forward: Promoting a Student-Centered Approach to Education Handoffs, Remediation, and Clerkship Success.

Issue: Throughout medical school, and especially during clerkships, students experience changing work and learning environments and are exposed to new academic, interpersonal, and professional challenges unique to clinical learning. Given the siloed nature of clinical rotations, students often "fall through the cracks" and may repeatedly struggle through clerkships without support and coaching from which they would otherwise benefit. Many institutions have grappled with creating feed forward processes, that is, educational handoffs in which information is shared among faculty about struggling students with the intention of providing longitudinal support to ensure their success, while protecting students from negative bias that may follow them throughout the remainder of their medical school tenure. Evidence: Here, the authors describe the feed forward processes of four medical schools. Each school's process relies on close collaboration between course directors and deans to identify students and develop intervention plans. Course leadership and administration are typically the primary drivers for long-term follow-up with students. The number of participants in the process varies, with only one school directly involving students. Two schools hold larger, regularly scheduled meetings with up to 12 faculty present in their institution's feed forward process. Across these institutions, students can "graduate" from the feed forward process once they achieve competency in the areas of concern. Implications: The authors believe the most important outcome achieved is the formalization and adherence to a feed forward process. Thus, risk to students in the form of negative bias is mitigated by the flow of information, the extent to which information is available, and permitting students to be part of the process. These exemplars give insight into variable approaches to feed forward systems adopted by medical schools and demonstrate highly visible methodologies by which educational leadership empower students and educators toward a shared goal of student progress and achievement.

Lenvatinib plus pembrolizumab in patients with either treatment-naive or previously treated metastatic renal cell carcinoma (Study 111/KEYNOTE-146): a phase 1b/2 study.

BACKGROUND: Despite advances in the first-line treatment of metastatic renal cell carcinoma (RCC), there is an unmet need for options to address disease progression during or after treatment with immune checkpoint inhibitors (ICIs). Pembrolizumab and lenvatinib are active as monotherapies in RCC; thus, we aimed to evaluate the combination of lenvatinib plus pembrolizumab in these patients. METHODS: We report results of the metastatic RCC cohort from an open-label phase 1b/2 study of lenvatinib plus pembrolizumab in patients aged at least 18 years with selected solid tumours and an Eastern Cooperative Oncology Group performance status of 0-1. Oral lenvatinib at 20 mg was given once daily along with intravenous pembrolizumab at 200 mg once every 3 weeks. Patients remained on study drug treatment until disease progression, development of unacceptable toxicity, or withdrawal of consent. Efficacy was analysed in patients with clear cell metastatic RCC receiving study drug by previous therapy grouping: treatment naive, previously treated ICI naive (previously treated with at least one line of therapy but not with an anti-PD-1 or anti-PD-L1 ICI), and ICI pretreated (ie, anti-PD-1 or anti-PD-L1) patients. Safety was analysed in all enrolled and treated patients. The primary endpoint was the objective response rate at week 24 per immune-related Response Evaluation Criteria In Solid Tumors (irRECIST) by investigator assessment. This trial is registered with ClinicalTrials.gov (NCT02501096) and with the EU Clinical Trials Register (EudraCT2017-000300-26), and is closed to new participants. FINDINGS: Between July 21, 2015, and Oct 16, 2019, 145 patients were enrolled in the study. Two patients had non-clear cell RCC and were excluded from the efficacy analysis (one in the treatment-naive group and one in the ICI-pretreated group); thus, the population evaluated for efficacy comprised 143 patients (n=22 in the treatment-naive group, n=17 in the previously treated ICI-naive group, and n=104 in the ICI-pretreated group). All 145 enrolled patients were included in the safety analysis. The median follow-up was 19·8 months (IQR 14·3-28·4). The number of patients with an objective response at week 24 by irRECIST was 16 (72·7%, 95% CI 49·8-89·3) of 22 treatment-naive patients, seven (41·2%, 18·4-67·1) of 17 previously treated ICI-naive patients, and 58 (55·8%, 45·7-65·5) of 104 ICI-pretreated patients. Of 145 patients, 82 (57%) had grade 3 treatment-related adverse events and ten (7%) had grade 4 treatment-related adverse events. The most common grade 3 treatment-related adverse event was hypertension (30 [21%] of 145 patients). Treatment-related serious adverse events occurred in 36 (25%) patients, and there were three treatment-related deaths (upper gastrointestinal haemorrhage, sudden death, and pneumonia). INTERPRETATION: Lenvatinib plus pembrolizumab showed encouraging antitumour activity and a manageable safety profile and might be an option for post-ICI treatment of metastatic RCC.

Is Training in a Primary Care Internal Medicine Residency Associated with a Career in Primary Care Medicine?

PURPOSE: Professional and governmental organizations recommend an ideal US physician workforce composed of at least 40 % primary care physicians. They also support primary care residencies to promote careers in primary care. Our study examines the relationship between graduation from a primary care or categorical internal medicine residency program and subsequent career choice. METHODS: We conducted a cross-sectional electronic survey of a cohort of internal medicine residency alumni who graduated between 2001 and 2010 from a large academic center. Our primary predictor was graduation from a primary care versus a categorical internal medicine program and our primary outcome is current career role. We performed chi-square analysis comparing responses of primary care and categorical residents. RESULTS: We contacted 481 out of 513 alumni, of whom 322 responded (67 %). We compared 106 responses from primary care alumni to 169 responses from categorical alumni. Fifty-four percent of primary care alumni agreed that the majority of their current clinical work is in outpatient primary care vs. 20 % of categorical alumni (p < 0.001). While 92.5 % of primary-care alumni were interested in a primary care career prior to residency, only 63 % remained interested after residency. Thirty of the 34 primary care alumni (88 %) who lost interest in a primary care career during residency agreed that their ambulatory experience during residency influenced their subsequent career choice. CONCLUSIONS: A higher percentage of primary care alumni practice outpatient primary care as compared to categorical alumni. Some alumni lost interest in primary care during residency. The outpatient clinic experience may impact interest in primary care.

Novel atherosclerotic risk factors and angiographic profile of young Gujarati patients with acute coronary syndrome.

OBJECTIVES: In this study we aimed to analyse the frequency of atherosclerotic risk factors with focus to novel risk factors for coronary artery disease and angiographic profile in young (≤ 40 years) acute coronary syndrome (ACS) patient with healthy controls in Gujarat, India. METHODS: Between January 2008 and December 2012, 109 consecutive young patients aged ≤ 40 years old, diagnosed to have ACS were included in the study. All ACS patients underwent diagnostic coronary angiography. An equivalent age and sex matched population without coronary disease with similar risk factors without tobacco considered a control group. All angiographic patients were evaluated for conventional risk factors for coronary artery disease like diabetes mellitus, hypertension, smoking, obesity as well as novel atherogenic risk factors like high sensitivity C-reactive protein (Hs-CRP), Lipoprotein(a) [LP(a)], homocysteine, apolipoprotein A1 (ApoA1) and B (ApoB). RESULT: In a study group, out of 109 young patients, 90 (82.6%) patients were presented to our hospital as ST-segment elevation myocardial infarction (STEMI), 10 (9.2%) presented as known non-ST-elevation myocardial infarction (NSTEMI) and 9 (8.3%) presented as unstable angina (UA). Serum cholesterol, triglycerides, LDL, LP(a) and lipid tetrad index were significantly higher in the study group whereas the HDL levels significantly lower as compared to the control group. CONCLUSION: A quite common risk factors of premature CAD are smoking, high Hs-CRP, high LP(a), hyperhomocysteinaemia and positive family history in the young ACS. Most common presentation of ACS in young was STEMI. On angiography, single vessel involvement was the most common finding.

The Gender Spectrum of In-hospital Survival Post Primary Percutaneous Coronary Intervention for ST Elevation Myocardial Infarction: Exploring Age-driven Trends.

Background: The study was aimed to evaluate gender difference and age & gender specific interaction of in-hospital outcomes of patients with ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods: This was a prospective cohort study of 1748 patients with STEMI undergoing primary PCI. The study was dichotomised according to gender to evaluate the difference in the outcome. The study was further stratified based on an age cut-off of 75 years to examine the age-specific gender relationship in survival outcomes. Independent variables for in-hospital mortality were analysed through logistic regression. Results: There were 314 (17.96%) females with an average age of 60.80 years and 1434 (82.03%) males with an average age of 54.87 years. The prevalence of diabetes (24.8% vs. 13.2%) and hypertension (33.1% vs. 12.9%) was significantly higher in female patients compared to male patients, whereas the significantly higher number of male patients were smokers. On multivariate analysis, odds of female gender OR = 3.54 (1.37-9.17), killip class >2 OR = 3.05 (1.97-4.71) and baseline creatinine OR = 2.27 (1.22-4.23) were found as significant predictors of in-hospital mortality. The crude odds ratio of 2.35 (1.49-3.72) and adjusted OR of 2.05 (1.27-3.30) for female mortality was significant among patients aged <75-years. While patients with ≥75-years of age, the mortality difference was insignificant. Conclusion: Although the incidence of STEMI was higher in male compared to female patients, female patients had two-fold higher in-hospital mortality than male. Female gender was an independent predictor for in-hospital mortality in patients <75-years of age.

Compassionate Off-Ramps: The Availability of Terminal Master's Degrees in US Medical Schools.

Medical students who underperform or find they are not a "good fit" for medicine have limited options. A terminal master's degree represents an exit alternative that recognizes students' completed coursework and acknowledges their commitment to the medical sciences. Although medical educators have called for the creation of such programs, termed "compassionate off-ramps," the prevalence of degree offerings in US programs is unknown. In the fall of 2020, a survey was sent to Student Affairs Deans at 141 LCME-accredited MD programs; 73 institutions responded (52%). Terminal master's degrees were offered by 19% of respondent institutions (n = 13). While 85% of those without a terminal master's (n = 48) endorsed degree benefits, only 36% (n = 21) had plans to create the degree. This study demonstrates that few US medical schools offer a terminal master's degree, leaving students who exit medicine with high levels of debt without an avenue for a degree to support employment or future academic pursuits. The authors identify implications for students, particularly those who are at a higher risk of failing Step 1, such as students who are underrepresented in medicine, socioeconomically disadvantaged, or who have a disability and are unaccommodated. Potential barriers to terminal master's program creation are identified and mitigating strategies are recommended.

Clinical characteristics and comorbidities associated with SARS-CoV-2 breakthrough infection in the University of California Healthcare Systems.

BACKGROUND: To evaluate the degree to which clinical comorbidities or combinations of comorbidities are associated with SARS-CoV-2 breakthrough infection. MATERIALS AND METHODS: A breakthrough infection was defined as a positive test at least 14 days after a full vaccination regimen. Logistic regression was used to calculate aORs, which were adjusted for age, sex, and race information. RESULTS: A total of 110,380 patients from the UC CORDS database were included. After adjustment, stage 5 CKD due to hypertension (aOR: 7.33; 95% CI: 4.86-10.69; p<.001; power=1) displayed higher odds of infection than any other comorbidity. Lung transplantation history (aOR: 4.79; 95% CI: 3.25-6.82; p<.001; power= 1), coronary atherosclerosis (aOR: 2.12; 95% CI: 1.77-2.52; p<.001; power=1), and vitamin D deficiency (aOR: 1.87; 95% CI: 1.69-2.06; p<.001; power=1) were significantly correlated to breakthrough infection. Patients with obesity in addition to essential hypertension (aOR: 1.74; 95% CI: 1.51-2.01; p<.001; power=1) and anemia (aOR: 1.80; 95% CI: 1.47-2.19; p<.001; power=1) were at additional risk of breakthrough infection compared to those with essential hypertension and anemia alone. CONCLUSIONS: Further measures should be taken to prevent breakthrough infection for individuals with these conditions, such as acquiring additional doses of the SARS-CoV-2 vaccine to boost immunity.

A SBIRT curriculum for medical residents: development of a performance feedback tool to build learner confidence.

A major barrier to actualizing the public health impact potential of screening, brief intervention, and referral to treatment (SBIRT) is the suboptimal development and implementation of evidence-based training curricula for healthcare providers. As part of a federal grant to develop and implement SBIRT training in medical residency programs, the authors assessed 95 internal medicine residents before they received SBIRT training to identify self-reported characteristics and behaviors that would inform curriculum development. Residents' confidence in their SBIRT skills significantly predicted SBIRT practice. Lack of experience dealing with alcohol or drug problems and discomfort in dealing with these issues were significantly associated with low confidence. To target these barriers, the authors revised their SBIRT curriculum to increase residents' confidence in their skills and developed an innovative SBIRT Proficiency Checklist and Feedback Protocol for skills practice observations. Qualitative feedback suggests that, despite the discomfort residents experience in being observed, a proficiency checklist and feedback protocol appear to boost learner confidence.

Delirium.

Delirium is an acute and fluctuating disorder characterized by a disturbance in attention and cognition. Delirium is underdiagnosed by clinicians, but there are excellent diagnostic tools using history and physical examination that can assist clinicians in making the diagnosis in multiple settings (ie, CAM, CAM-ICU, 3D-CAM, bCAM, 4AT, and UB-CAM). Delirium is caused by underlying medical conditions and is often multifactorial, so a full diagnosis requires a careful assessment for a wide range of underlying conditions. Physical examination has not been well studied in this regard, but still can provide useful clues to the clinician.

Rosai-Dorfman disease in a symptomatic elderly man.

An 81-year-old man presented with anemia, fatigue, weight loss, and recurrent urinary tract infections and was found to have diffuse large adenopathy and infiltrating renal masses. Surgical excision of a lymph node and histologic evaluation led to the diagnosis of Rosai-Dorfman disease, a rare histioproliferative condition that classically presents with enlarged cervical lymph nodes bilaterally. It also can involve additional nodal chains and/or have extranodal manifestations. The condition can self-resolve or have periods of remission and reactivation.

Impact of USMLE Step-1 accommodation denial on US medical schools: A national survey.

INTRODUCTION: In 2019, 4.6% of US-MD students self-identified as students with disabilities (SWD); many of these students will require accommodations on the USMLE Step-1 examination. Given the high-stakes nature of Step-1 for medical school advancement and residency match, SWD denied accommodations on Step-1 face considerable consequences. To date no study has investigated the rate of accommodation denial and its impact on medical school operations. METHODS: To investigate the rate of accommodation denial and evaluate whether Step-1 accommodation denial impacts medical school operations, a 10-question survey was sent to Student Affairs Deans and disability resource professionals at all fully-accredited US-MD granting programs. Two open-ended questions were analyzed using qualitative content analysis. RESULTS: Seventy-three of the 141 schools responded (52%). In the 2018-2019 academic year, 276 students from 73 schools applied for Step-1 accommodations. Of these, 144 (52%) were denied. Of those denied, 74/144 (51%) were delayed entry into the next phase of curriculum and 110/144 (76%) took the Step-1 exam unaccommodated. Of the 110 who took Step-1 without accommodations, 35/110 (32%) failed the exam, and 4/110 (3%) withdrew or were dismissed following exam failure. Schools reported varied investments of time and financial support for students denied accommodations, with most schools investing less than 20 hours (67%) and less than $1,000.00 (69%). Open-responses revealed details regarding the impact of denial on schools and students including frustration with process; financial and human resources allocation; delay in student progression; lack of resourcing and expertise; and emotional and financial burdens on students. DISCUSSION: Step-1 accommodation denial has non-trivial financial, operational, and career impacts on medical schools and students alike. The cause of accommodation denial in this population requires further exploration.

The Performance and Trajectory of Medical Students With Disabilities: Results From a Multisite, Multicohort Study.

PURPOSE: To conduct a post-Americans with Disabilities Act Amendments Act of 2008 multisite, multicohort study called the Pathways Project to assess the performance and trajectory of medical students with disabilities (SWDs). METHOD: From June to December 2020, the authors conducted a matched cohort study of SWDs and nondisabled controls from 2 graduating cohorts (2018 and 2019) across 11 U.S. MD-granting medical schools. Each SWD was matched with 2 controls, one from their institution and, whenever possible, one from their cohort for Medical College Admission Test score and self-reported gender. Outcome measures included final attempt Step 1 and Step 2 Clinical Knowledge scores, time to graduation, leave of absence, matching on first attempt, and matching to primary care. RESULTS: A total of 171 SWDs and 341 controls were included; the majority of SWDs had cognitive/learning disabilities (118/171, 69.0%). Compared with controls, SWDs with physical/sensory disabilities had similar times to graduation (88.6%, 95% confidence interval [CI]: 77.0, 100.0 vs 95.1%, 95% CI: 90.3, 99.8; P = .20), Step 1 scores (229.6 vs 233.4; P = .118), and match on first attempt (93.9%, 95% CI: 86.9, 100.0 vs 94.6%, 95% CI: 91.8, 97.4; P = .842), while SWDs with cognitive/learning disabilities had lower Step 1 scores (219.4; P < .001) and were less likely to graduate on time (81.2%, 95% CI: 69.2, 93.2; P = .003) and match on first attempt (85.3%, 95% CI: 78.0, 92.7; P = .009). Accommodated SWDs had Step 1 scores that were 5.9 points higher than nonaccommodated SWDs (95% CI: -0.7, 12.5; P = .08). CONCLUSIONS: Structural barriers remain for SWDs with cognitive/learning disabilities, which could be partially mitigated by accommodations on high-stakes exams.

A study of narrow QRS tachycardia with emphasis on the clinical features, ECG, electrophysiology/radiofrequency ablation.

Aim: Atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular reentrant tachycardia (AVRT) are the most common forms of paroxysmal regular supraventricular tachycardias. Materials & methods: The clinical, ECG and electrophysiological findings of 121 patients with narrow QRS tachycardia were evaluated prospectively. Results: A total of 75 (62%) of the patients had AVNRT while 46 (38%) had AVRT. Pounding sensation in the neck (40 vs 15.2%; p = 0.004), presynope (26.7 vs 56.5%; p = 0.001) identifiable P wave after QRS complex (25.3 vs 73.9%; p = 0.001), pseudo r'/s waves (45.3 vs 4.3%; p = 0.001), limb leads ST-T changes (34.7 vs 60.9%; p = 0.004) were the significant changes observed. A total of 94.7% of AVNRT and 87% of AVRT could be diagnosed correctly considering both clinical and ECG criteria. Conclusion: Pounding sensation in the neck and presyncope along with ECG features like identifiable P wave after QRS complex, pseudo r'/s waves and limb lead ST-T changes very accurately differentiate AVNRT and AVRT.

Disparities in COVID-19 Outcomes by Race, Ethnicity, and Socioeconomic Status: A Systematic-Review and Meta-analysis.

Importance: COVID-19 has disproportionately affected racial and ethnic minority groups, and race and ethnicity have been associated with disease severity. However, the association of socioeconomic determinants with racial disparities in COVID-19 outcomes remains unclear. Objective: To evaluate the association of race and ethnicity with COVID-19 outcomes and to examine the association between race, ethnicity, COVID-19 outcomes, and socioeconomic determinants. Data Sources: A systematic search of PubMed, medRxiv, bioRxiv, Embase, and the World Health Organization COVID-19 databases was performed for studies published from January 1, 2020, to January 6, 2021. Study Selection: Studies that reported data on associations between race and ethnicity and COVID-19 positivity, disease severity, and socioeconomic status were included and screened by 2 independent reviewers. Studies that did not have a satisfactory quality score were excluded. Overall, less than 1% (0.47%) of initially identified studies met selection criteria. Data Extraction and Synthesis: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Associations were assessed using adjusted and unadjusted risk ratios (RRs) and odds ratios (ORs), combined prevalence, and metaregression. Data were pooled using a random-effects model. Main Outcomes and Measures: The main measures were RRs, ORs, and combined prevalence values. Results: A total of 4 318 929 patients from 68 studies were included in this meta-analysis. Overall, 370 933 patients (8.6%) were African American, 9082 (0.2%) were American Indian or Alaska Native, 101 793 (2.4%) were Asian American, 851 392 identified as Hispanic/Latino (19.7%), 7417 (0.2%) were Pacific Islander, 1 037 996 (24.0%) were White, and 269 040 (6.2%) identified as multiracial and another race or ethnicity. In age- and sex-adjusted analyses, African American individuals (RR, 3.54; 95% CI, 1.38-9.07; P = .008) and Hispanic individuals (RR, 4.68; 95% CI, 1.28-17.20; P = .02) were the most likely to test positive for COVID-19. Asian American individuals had the highest risk of intensive care unit admission (RR, 1.93; 95% CI, 1.60-2.34, P < .001). The area deprivation index was positively correlated with mortality rates in Asian American and Hispanic individuals (P < .001). Decreased access to clinical care was positively correlated with COVID-19 positivity in Hispanic individuals (P < .001) and African American individuals (P < .001). Conclusions and Relevance: In this study, members of racial and ethnic minority groups had higher risks of COVID-19 positivity and disease severity. Furthermore, socioeconomic determinants were strongly associated with COVID-19 outcomes in racial and ethnic minority populations.

Isotopes (δ18O, δD and 3H) variations in groundwater with emphasis on salinization in the state of Punjab, India.

The state of Punjab has a dominant agrarian economy and is considered India's bread basket. However, it is now under the problem of falling agro-economy primarily because of pervasive depletion of groundwater levels and deteriorating groundwater quality in south-west Punjab, but increasing salinity is a major concern. The irrigation requirements of crops are fulfilled by groundwater and canal water but the introduction of canal irrigation has led to waterlogging and subsequent salinization rendering large fertile-land areas becoming unproductive mainly in the south-western part of Punjab. There was an apprehension that excessive withdrawal of groundwater might have caused a reversal of natural groundwater flow pattern that might have caused ingress of saline water into fresh groundwater region of central Punjab. To address the apprehension related to the rise in groundwater salinity and its subsequent ingression in the fresh-water zone and suggest suitable management solutions, a study was undertaken to analyse the data related to salinity, isotopes, land-use and land cover (LULC) along with field and laboratory experimental results. The depth-wise isotope analysis shows that there is a large variation in isotopic signatures of shallow and intermediate aquifers and it decreases with the depth of aquifers (150-250 m). It appears that very deep groundwater (>250 m) is relatively isolated and does not show a large variation or mixing effect. Tritium analysis shows that dynamic groundwater is actively recharged through canal, river, and/or rain. The presence of modern groundwater at deeper depth indicates a good interconnection between shallow and deep groundwater. Interpretations of the results show that the canal is the main source of groundwater recharge in south-west Punjab and the evaporation process is responsible for increasing the salinity hazard. In the central parts of Punjab, groundwater and rain are the main sources of groundwater recharge, while rain is the main source of groundwater recharge in the Kandi area. In the south-west Punjab, some primary salinity has formed as a result of mineral dissolution which has further increased due to evaporative enrichment.

National Prevalence of Disability and Clinical Accommodations in Medical Education.

BACKGROUND: This study aimed to evaluate and report the national prevalence of disability across undergraduate medical education (UME) and examine differences in the category of disability, and accommodation practices between allopathic (MD)- and osteopathic (DO)-granting programs. METHODS: Between May 20 and June 30, 2020, 75% of institutional representatives at eligible DO schools responded to a web-based survey. The survey assessed the aggregate prevalence of disabled DO students, prevalence of DO students by category of disability, and prevalence of accommodations granted. Descriptive statistics were used to summarize results. Using 2019 MD data, comparisons were made between MD and DO programs to calculate overall prevalence and differences in accommodation practices across undergraduate medical education. RESULTS: DO-granting programs reported a disability prevalence of 4.27% of the total enrollment. Attention-deficit/hyperactivity disorder (ADHD), psychological disabilities, and chronic health disabilities were reported most frequently. DO-granting programs reported higher rates of ADHD than the MD-granting program. The national pooled prevalence of disability across MD- and DO-granting programs was 4.52%. MD-granting programs reported a higher number of students with disabilities and higher rates of psychological disabilities when compared with DO-granting programs. One hundred percent of DO students disclosing disability received some form of accommodation. General clinical accommodations were more frequently provided in MD-granting programs when compared to DO-granting programs. CONCLUSIONS: This study provides the first comprehensive prevalence of US medical student disability and accommodations. Additionally, these data may serve as a benchmark for DO programs, with implications for curricular development, instructional planning and disability support, and resource allocation in medical education.

Frontier review on the propensity and repercussion of SARS-CoV-2 migration to aquatic environment.

Increased concern has recently emerged pertaining to the occurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in aquatic environment during the current coronavirus disease 2019 (COVID-19) pandemic. While infectious SARS-CoV-2 has yet to be identified in the aquatic environment, the virus potentially enters the wastewater stream from patient excretions and a precautionary approach dictates evaluating transmission pathways to ensure public health and safety. Although enveloped viruses have presumed low persistence in water and are generally susceptible to inactivation by environmental stressors, previously identified enveloped viruses persist in the aqueous environment from days to several weeks. Our analysis suggests that not only the surface water, but also groundwater, represent SARS-CoV-2 control points through possible leaching and infiltrations of effluents from health care facilities, sewage, and drainage water. Most fecally transmitted viruses are highly persistent in the aquatic environment, and therefore, the persistence of SARS-CoV-2 in water is essential to inform its fate in water, wastewater and groundwater and subsequent human exposure.

Lessons learned about integrating a medical school curriculum: perceptions of students, faculty and curriculum leaders.

OBJECTIVE: Recent educational reform in US medical schools has created integrated curricular structures. This study investigated how stakeholders in a newly integrated curriculum - students, course directors and curriculum leaders - define integration and perceive its successes and challenges during its first year. METHODS: We conducted interviews with curriculum reform leaders, course directors and first year medical students. Interview transcripts were analysed for themes, which were compared within and across stakeholder groups. RESULTS: Three curriculum leaders, four Year 1 course directors and six Year 1 medical students were interviewed. Fifteen students participated in a group interview. Four major themes emerged: interdisciplinary teaching; interdisciplinary faculty collaboration; building curricular links, and sequencing and framing curricular content. Cross-group analysis revealed participant agreement that an integrated curriculum required interdisciplinary teaching, clinical application and careful oversight. Differences among groups were also identified. Faculty (course directors and curriculum leaders) discussed faculty collaboration and the challenges of faculty buy-in and course implementation. Students highlighted the impact of integration on their learning and the challenges of sequencing and scaffolding content. Both students and course directors focused on course monitoring and conceptual links for student learning. CONCLUSIONS: Integrating a curriculum is a complex process. It is differentially understood and experienced by students and faculty, and can refer to instructional method, content, faculty work or synthesis of knowledge in the minds of learners. It can occur at different rates and some subjects are integrated more easily than others. We point to some specific considerations as medical schools embark on curriculum reform.
