Thoracic splenosis: an important consideration in oncology patients

SummarySplenosis is the implantation of ectopic splenic tissue after splenic injury or splenectomy. Signs and symptoms of splenosis vary based on anatomic location; however, it remains asymptomatic in many cases. On radiographic imaging, splenosis often appears as a soft tissue mass and can be diagnosed using heat-damaged red blood cell scintigraphy, a non-invasive imaging modality. Radiographic findings of splenosis on imaging may be suspicious for metastatic disease in patients with known solid organ tumours. It is important to have a high degree of suspicion for splenosis with known history of splenic trauma or splenectomy in order to avoid invasive procedures and guide appropriate management.

Stem Cells and Congenital Heart Disease: The Future Potential Clinical Therapy Beyond Current Treatment

Congenital heart disease (CHD) is the most common congenital anomaly in newborns. Current treatment for cyanotic CHD largely relies on the surgical intervention; however, significant morbidity and mortality for patients with CHD remain. Recent research to explore new avenues of treating CHD includes the utility of stem cells within the field. Stem cells have since been used to both model and potentially treat CHD. Most clinical applications to date have focused on hypoplastic left heart syndrome. Here, we examine the current role of stem cells in CHD and discuss future applications within the field.

Anticoagulation and BMI: effect of high body weight on the safety and efficacy of direct oral anticoagulants

Obesity is an epidemic with rising prevalence, and obese patients are predisposed to comorbid conditions that increase risk for thromboembolic events. It is critical to identify safe and effective anticoagulation therapy for use in this population. Direct oral anticoagulants (DOACs) are a preferred option for anticoagulation in patients of normal weight due to many benefits and equivalent safety and efficacy to their vitamin K antagonist counterparts. However, the safety and efficacy of DOACs in obese patients is not well understood. This review describes recent studies on the pharmacokinetics, safety and efficacy, and clinical outcomes of the DOACs apixaban, rivaroxaban, edoxaban and dabigatran in obese patient populations. DOACs may be a beneficial alternative to vitamin K antagonist therapy in obese patient populations.

A review of cardiac autonomics: from pathophysiology to therapy

The effective management of cardiovascular diseases requires knowledge of intrinsic and extrinsic innervation of the heart and an understanding of how perturbations of said components affect cardiac function. The innate cardiac conduction system, which begins with cardiac pacemaker cells and terminates with subendocardial Purkinje fibers, is modulated by said systems. The intrinsic component of the cardiac autonomic nervous system, which remains incompletely elucidated, consists of intracardiac ganglia and interconnecting neurons that tightly regulate cardiac electrical activity. Extrinsic components of the autonomic nervous system, such as carotid baroreceptors and renin-angiotensin-aldosterone system, modulate sympathetic input to the heart through the stellate ganglion and parasympathetic input via the vagus nerve. There remains a need for additional therapies to treat conditions, such as advanced heart failure and refractory arrhythmias, and a better understanding of autonomics may be key to their development.

Utility of Ct values in differentiating COVID-19 reinfection versus prolonged viral shedding in an immunocompromised patient

We describe the case of a 26-year-old man who presented to an outside hospital with concerns of blurred vision. He subsequently tested positive for COVID-19 and his lab work suggested acute leukaemia. The patient was admitted to our hospital and completed a course of remdesivir. He eventually tested negative for COVID-19 before initiating chemotherapy. Two days after starting chemotherapy, he developed a neutropenic fever and tested positive for COVID-19. Through this case, we aim to bring attention to patients who recurrently test positive with COVID-19 PCR testing, thereby causing a dilemma of differentiating between reinfections and prolonged shedding of the virus, as well as understand and use cycle threshold values to discern these aetiologies.

Out-of-Pocket Costs of Insulin and Diabetes-Related Supplies Among Patients With Type 1 Diabetes

The cost of insulin has increased exponentially since its discovery in the 1920s, but the degree to which this financial burden has been transferred to patients is unknown. The present study is a retrospective analysis using claims data for privately insured patients with type 1 diabetes from 2005 to 2017. We quantify the mean annual out-of-pocket costs for insulin and diabetes-related supplies during the study period. It is imperative for health care professionals to be aware of this cost, and we hope that these findings serve as a call for legislation to cap the rising price of insulin.

Autoimmune heparin-induced thrombocytopenia: a rare manifestation of COVID-19

We describe the case of a 65-year-old male who presented to an outside hospital for shortness of breath, nausea and vomiting 8 days after testing positive for COVID-19. Initial workup revealed massive bilateral pulmonary emboli and thrombocytopenia. The patient was then admitted to our hospital, received an inferior vena cava filter and initially started on argatroban for autoimmune heparin-induced thrombocytopenia (HIT) prophylaxis. On hospital stay day 6, labs revealed a diagnosis of HIT in the setting of COVID-19. This case highlights the rare occurrence of a patient developing HIT without heparin exposure and in the setting of a novel infectious agent, COVID-19.

Journal peer review: a bar or bridge? An analysis of a paper's revision history and turnaround time, and the effect on citation

Journal peer review lies at the heart of academic quality control. This article explores the journal peer review process and seeks to examine how the reviewing process might itself contribute to papers, leading them to be more highly cited and to achieve greater recognition. Our work builds on previous observations and views expressed in the literature about (a) the role of actors involved in the research and publication process that suggest that peer review is inherent in the research process and (b) on the contribution reviewers themselves might make to the content and increased citation of papers. Using data from the journal peer review process of a single journal in the Social Sciences field (Business, Management and Accounting), we examine the effects of peer review on papers submitted to that journal including the effect upon citation, a novel step in the study of the outcome of peer review. Our detailed analysis suggests, contrary to initial assumptions, that it is not the time taken to revise papers but the actual number of revisions that leads to greater recognition for papers in terms of citation impact. Our study provides evidence, albeit limited to the case of a single journal, that the peer review process may constitute a form of knowledge production and is not the simple correction of errors contained in submitted papers.

The Health Professions Education Pathway: Preparing Students, Residents, and Fellows to Become Future Educators

PROBLEM

Training the next generation of health professionals requires leaders, innovators, and scholars in education. Although many medical schools and residencies offer education electives or tracks focused on developing teaching skills, these programs often omit educational innovation, scholarship, and leadership and are narrowly targeted to one level of learner.

INTERVENTION

The University of California San Francisco created the Health Professions Education Pathway for medical students, residents, and fellows as well as learners from other health professional schools. The Pathway applies the theoretical framework of communities of practice in its curricular design to promote learner identity formation as future health professions educators. It employs the strategies of engagement, imagination, and alignment for identity formation.

CONTEXT

Through course requirements, learners engage and work with members of the educator community of practice to develop the knowledge and skills required to participate in the community. Pathway instructors are faculty members who model a breadth of educator careers to help learners imagine personal trajectories. Last, learners complete mentored education projects, adopting scholarly methods and ethics to align with the broader educator community of practice.

OUTCOME

From 2009 to 2014, 117 learners participated in the Pathway. Program evaluations, graduate surveys, and web-based searches revealed positive impacts on learner career development. Learners gained knowledge and skills for continued engagement with the educator community of practice, confirmed their career aspirations (imagination), joined an educator-in-training community (engagement/imagination), and disseminated via scholarly meetings and peer-reviewed publications (alignment).

LESSONS LEARNED

Learners identified engagement with the learner community as the most powerful aspect of the Pathway; it provided peer support for imagining and navigating the development of their dual identities in the clinician and educator communities of practice. Also important for learner success was alignment of their projects with the goals of the local educator community of practice. Our community of practice approach to educator career development has shown promising early outcomes by nurturing learners' passion for teaching; expanding their interest in educational leadership, innovation, and scholarship; and focusing on their identity formation as future educators.

Faculty development efforts to promote screening, brief intervention, and referral to treatment (SBIRT) in an internal medicine faculty-resident practice

BACKGROUND

Screening, brief intervention, and referral to treatment (SBIRT) is a practical means to address substance misuse in primary care. Important barriers to implementing SBIRT include adequacy of training and provider confidence as well as logistical hurdles and time constraints. A faculty development initiative aimed at increasing SBIRT knowledge and treatment of substance use disorders (SUDs) should lead to increased use of SBIRT by faculty and the residents they teach. This study examined how a faculty development program to promote SBIRT influenced faculty practice and resident teaching.

METHODS

This was a cross-sectional study of faculty exposed to multiple SBIRT educational interventions over a 5-year period in an academic faculty-resident general medicine practice. Participants completed a brief online survey followed by a semistructured interview. Quantitative responses were examined descriptively. Qualitative questions were reviewed to identify key themes.

RESULTS

Fifteen of 29 faculty (52%) completed the survey and 13 (45%) completed the interviews regarding faculty development interventions. Faculty thought that SBIRT was an important skill and had confidence in screening for substance use disorders, although confidence in making treatment referrals and prescribing pharmacotherapy were rated lower. Many faculty reported screening more frequently for SUDs after attending faculty development sessions. However, several reported that the training did not improve their SBIRT teaching to residents during clinic precepting sessions. To improve uptake of SBIRT, a majority of faculty recommended electronic health record (EHR) alerts.

CONCLUSIONS

SBIRT is a highly valued set of skills, and training may enhance rates of screening for substance misuse. However, participants did not report a substantial change in SBIRT teaching as a result of faculty development. In the future, small, targeted faculty development sessions, potentially involving strategies for using the electronic health record (EHR), may be an effective way to enhance primary care SBIRT skills.

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.

The impact of an objective structured teaching evaluation on faculty teaching skills

BACKGROUND

Objective structured teaching evaluations (OSTEs) have been utilized to evaluate educational curricula and for resident and faculty development.

PURPOSE

This study examines the impact of an OSTE on faculty teaching effectiveness and faculty satisfaction.

METHODS

From 2004 to 2007, 46 faculty members participated in the OSTE. Faculty assessed their teaching abilities with a retrospective pre-post-test analysis. Faculty teaching evaluations for the 6 months before and after the OSTE were compared. Faculty participants completed satisfaction questionnaires regarding their OSTE experience and made teaching plans for the future.

RESULTS

After the OSTE, faculty reported statistically significant improvements in all self-assessed teaching skills. There was, however, no improvement in their teaching evaluations. Faculty satisfaction with the OSTE experience was high. They indicated teaching plans incorporating lessons from the OSTE.

CONCLUSIONS

Faculty felt the OSTE was a rewarding experience and reported improvement in their teaching abilities; however, faculty teaching evaluations did not improve.

Developing educators, investigators, and leaders during internal medicine residency: the area of distinction program

BACKGROUND

Professional organizations have called for individualized training approaches, as well as for opportunities for resident scholarship, to ensure that internal medicine residents have sufficient knowledge and experience to make informed career choices.

CONTEXT AND PURPOSE

To address these training issues within the University of California, San Francisco, internal medicine program, we created the Areas of Distinction (AoD) program to supplement regular clinical duties with specialized curricula designed to engage residents in clinical research, global health, health equities, medical education, molecular medicine, or physician leadership. We describe our AoD program and present this initiative's evaluation data. METHODS AND PROGRAM EVALUATION: We evaluated features of our AoD program, including program enrollment, resident satisfaction, recruitment surveys, quantity of scholarly products, and the results of our resident's certifying examination scores. Finally, we described the costs of implementing and maintaining the AoDs.

RESULTS

AoD enrollment increased from 81% to 98% during the past 5 years. Both quantitative and qualitative data demonstrated a positive effect on recruitment and improved resident satisfaction with the program, and the number and breadth of scholarly presentations have increased without an adverse effect on our board certification pass rate.

CONCLUSIONS

The AoD system led to favorable outcomes in the domains of resident recruitment, satisfaction, scholarship, and board performance. Our intervention showed that residents can successfully obtain clinical training while engaging in specialized education beyond the bounds of core medicine training. Nurturing these interests 5 empower residents to better shape their careers by providing earlier insight into internist roles that transcend classic internal medicine training.

Educating generalists: factors of resident continuity clinic associated with perceived impact on choosing a generalist career

BACKGROUND

Fewer residents are choosing general internal medicine (GIM) careers, and their choice 5 be influenced by the continuity clinic experience during residency. We sought to explore the relationship between resident satisfaction with the continuity clinic experience and expressed interest in pursuing a GIM career.

METHODS

We surveyed internal medicine residents by using the Veterans Health Administration Office of Academic Affiliations Learners' Perceptions Survey-a 76-item instrument with established reliability and validity that measures satisfaction with faculty interactions, and learning, working, clinical, and physical environments, and personal experience. We identified 15 reliable subscales within the survey and asked participants whether their experience would prompt them to consider future employment opportunities in GIM. We examined the association between satisfaction measures and future GIM interest with 1-way analyses of variance followed by Student-Newman-Keuls post hoc tests.

RESULTS

Of 217 residents, 90 (41%) completed the survey. Residents felt continuity clinic influenced career choice, with 22% more likely to choose a GIM career and 43% less likely. Those more likely to choose a GIM career had higher satisfaction with the learning (P  =  .001) and clinical (P  =  .002) environments and personal experience (P < .001). They also had higher satisfaction with learning processes (P  =  .002), patient diversity (P < .001), coordination of care (P  =  .009), workflow (P  =  .001), professional/personal satisfaction (P < .001), and work/life balance (P < .001).

CONCLUSIONS

The continuity clinic experience 5 influence residents' GIM career choice. Residents who indicate they are more likely to pursue GIM based on that clinical experience have higher levels of satisfaction. Further prospective data are needed to assess if changes in continuity clinic toward these particular factors can enhance career choice.

Perspective: Creating the next generation of general internists: a call for medical education reform

The United States is faced with an increasing shortage of physicians in the primary care workforce. The number of medical school graduates selecting careers in primary care internal medicine has fallen dramatically since 1985. Although political, financial, and organizational reform of the medical system is necessary, these changes will address only part of the problem. Endeavors designed to ameliorate this current crisis in primary care practice must also address the education and training of future primary care internists. Learners require specialized training in primary care internal medicine to be able to provide high-quality, patient-centered, outcome-oriented care. This article examines the impact of educational interventions in undergraduate medical education (UME) and graduate medical education (GME) on primary care internal medicine career choice and makes suggestions for future educational changes. Suggested UME changes include providing early longitudinal clinical experiences and providing the option for an integrated ambulatory third year of training. Suggested GME changes include early, sustained exposure to general internal medicine and differentiated training tracks for residents interested in primary care. Key among these changes are that medical students and residents must have adequate mentorship from primary care internists and clinical experiences in highly functioning primary care settings established as patient-centered medical homes. Academic centers have a unique opportunity to contribute to these imperatives by reengineering the practice of primary care in a way that embodies the core values of effective, patient-centered care.

Activities of antistaphylococcal antibiotics towards the extracellular and intraphagocytic forms of Staphylococcus aureus isolates from a patient with persistent bacteraemia and endocarditis

Decreased susceptibility of Staphylococcus aureus to antistaphylococcal agents may be associated with inability to eradicate intracellular forms, which could explain therapeutic failures. This hypothesis was tested using clinical isolates obtained from a patient with persistent staphylococcal bacteraemia under therapy. Four isogenic isolates (three from tissue, one from blood) with increased MICs for vancomycin (1-4 mg/L) and for daptomycin (1-4 mg/L) were collected after an initial 16-day treatment with vancomycin-rifampicin-gentamicin, followed by 13-20 days of treatment with daptomycin-rifampicin-gentamicin. Isolates were tested for MICs and for: (i) vancomycin (BODIPY-FL-vancomycin) and daptomycin binding; (ii) cell wall turnover (loss of N-acetyl-d-[1-(14)C]glucosamine in 30 min after 1 h of labelling); and (iii) Triton X-100-induced autolysis. Extracellular (broth) and intracellular (THP-1 macrophages) activities of rifampicin, linezolid and fusidic acid at C(max), and of vancomycin, daptomycin, quinupristin-dalfopristin and oritavancin over a wide range of extracellular concentrations (with pharmacological modelling to determine E(max)), were measured at 24 h. Increases in vancomycin MICs correlated with increased drug binding, and decreased cell wall turnover and detergent-induced autolysis. Increases in daptomycin MICs correlated with decreased daptomycin binding. Intracellular activity was weak (E(max) <1 log(10) CFU decrease) for vancomycin against all isolates, and for daptomycin against isolates with MICs >1 mg/L. Among all antibiotics tested, only quinupristin-dalfopristin and oritavancin provided close to bactericidal intracellular activities (1.6-2.5 log(10) CFU decreases at C(max)). Determination of the intracellular susceptibility of S. aureus, combined with improved methods of diagnosis, could be useful when dealing with persistent staphylococcal infections and could improve therapy.

Factors affecting medical students' selection of an internal medicine residency program

OBJECTIVE

To determine factors that influence medical student selection of internal medicine residency programs by ethnicity and gender.

DESIGN/SETTING

A cross-sectional mailed survey of graduating medical students applying to four residency programs in 1999.

MEASUREMENTS

A five-point (5=most important) Likert scale was used to evaluate factors and included 14 items on location characteristics, 20 on program features, six on recruitment, three on future plans and three on advising.

RESULTS

Of 2,820 surveys, 1,005 were completed (36%). The most important factors to applicants were house staff morale (mean +/- SD, 4.5 +/- 0.7), academic reputation (4.5 +/-0.8), and positive interview experience (4.1 +/- 1.0). Women rated gender diversity of faculty (3.3 vs. 2.3, p=0.0001) and house staff (3.3 vs. 2.5, p=0.0001), location of residency program near spouse (4.2 vs. 3.9, p=0.0001) or spouse's job (3.8 vs. 3.5, p=0.0002) and emphasis on primary care (2.9 vs. 2.4, p=0.0001) more highly than men. Minority applicants were more likely than whites to identify the following factors as more important: ethnic diversity of patients (3.8 vs. 3.4, p=0.008), house staff (3.3 vs. 2.4, p<0.0001) and faculty (3.1 vs. 2.3, p<0.0001); service to the medically indigent (3.8 vs. 3.3, p=0.004); feeling of being wanted (3.8 vs. 3.4, p=0.002); and an academic environment supportive of ethnic minorities (3.5 vs. 2.3, p<0.0001).

CONCLUSIONS

Location and program factors are most important in influencing decisions to choose a residency program. However, women and minority applicants also place significant importance on family and diversity factors. Programs need to consider differential factors in recruitment of diverse students.

West Nile virus serosurvey and assessment of personal prevention efforts in an area with intense epizootic activity: Connecticut, 2000

West Nile virus (WNV) can cause large outbreaks of febrile illness and severe neurologic disease. This study estimates the seroprevalence of WNV infection and assesses risk perception and practices regarding potential exposures to mosquitoes of persons in an area with intense epizootics in 1999 and 2000. A serosurvey of persons aged > or = 12 years was conducted in southwestern Connecticut during October 10-15, 2000, using household-based stratified cluster sampling. Participants completed a questionnaire regarding concern for and personal measures taken with respect to WNV and provided a blood sample for WNV testing. Seven hundred thirty persons from 645 households participated. No person tested positive for WNV (95% CI: 0-0.5%). Overall, 44% of persons used mosquito repellent, 56% practiced > or = two personal precautions to avoid mosquitoes, and 61% of households did > or = two mosquito-source reduction activities. In multivariate analyses, using mosquito repellent was associated with age < 50 years, using English as the primary language in the home, being worried about WNV, being a little worried about pesticides, and finding mosquitoes frequently in the home (P<0.05). Females (OR = 2.0; CI = 1.2-2.9) and persons very worried about WNV (OR = 3.8; CI = 2.2-6.5) were more likely to practice > or = two personal precautions. Taking > or = two mosquito source reductions was associated with persons with English as the primary language (OR = 2.0; CI = 1.1-3.5) and finding a dead bird on the property (OR = 1.8; CI = 1.1-2.8). An intense epizootic can occur in an area without having a high risk for infection to humans. A better understanding of why certain people do not take personal protective measures, especially among those aged > or = 50 years and those whose primary language is not English, might be needed if educational campaigns are to prevent future WNV outbreaks.

Concurrent uveoretinitis and pineocytoma in a child suggests a causal relationship

Uveoretinitis was observed in a 9-year-old girl 6 months prior to the clinical appearance of a pineal tumour. Surgical removal was not successful but biopsy revealed a parenchymal neoplasm with differentiated pinealocytes and absent mitotic activity. Some of the tumour cells contained S-antigen, rhodopsin, and serotonin. Systemic glucocorticoid therapy followed by radiation therapy caused considerable reduction in size of the tumour and a complete normalisation of all eye symptoms. This report demonstrates for the first time that a pineocytoma can occur together with uveoretinitis in humans. The latter resembles the experimentally induced autoimmune uveoretinitis described in animals. It is speculated that the retinitis might reflect an autoimmune response to S-antigen present in some tumour cells of the pineocytoma.
