RESUMO

Physician solicitation of charitable contributions from patients-also known among other things as grateful patient fundraising-raises significant ethical concerns. These include pressure on patients to donate and the effects of this on the patient-physician relationship, potential expectations of donor patients for treatment that is not indicated or preferential care, justice and fairness issues, disclosure and use of confidential patient information for nontreatment purposes, and conflicts of interest. The patient-physician relationship and knowledge of the patient's medical history, clinical status, personal information, and financial circumstances are some of the reasons development and administrative officials might see physicians as strong potential fundraisers. But those are among the reasons grateful patient fundraising is ethically problematic. This American College of Physicians position paper explores these issues and offers guidance.

RESUMO

Introduction: Bedside cardiac assessment (BCA) is deficient across a spectrum of noncardiology trainees. Learners not taught BCA well may become instructors who do not teach well, creating a self-perpetuating problem. To improve BCA teaching and learning, we developed a high-quality, patient-centered curriculum for medicine clerkship students that could be flexibly implemented and accessible to other health professions learners. Methods: With a constructivist perspective, we aligned learning goals, activities, and assessments. The curriculum used a "listen before you auscultate" framework, capturing patient history as context for a six-step, systematic approach. In the flipped classroom, short videos and practice questions preceded two 1-hour class activities that integrated diagnostic reasoning, pathophysiology, physical diagnosis, and reflection. Activities included case discussions, jugular venous pressure evaluation, heart sound competitions, and simulated conversations with patients. Two hundred sixty-eight students at four US and international medical schools participated. We incorporated feedback, performed thematic analysis, and assessed learners' confidence and knowledge. Results: Low posttest data capture limited quantitative results. Students reported increased confidence in BCA ability. Knowledge increased in both BCA and control groups. Thematic analysis suggested instructional design strategies were effective and peer encounters, skills practice, and encounters with educators were meaningful. Discussion: The curriculum supported active learning of day-to-day clinical competencies and promoted professional identity formation alongside BCA ability. Feedback and increased confidence on the late-clerkship posttest suggested durable learning. We recommend approaches to confirm this and other elements of knowledge, skill acquisition, or behaviors and are surveying impacts on professional identity formation-related constructs.

RESUMO

INTRODUCTION: Despite the widespread use of mentholated cigarettes, lower cessation rates, and disproportionately high smoking-related morbidity among Blacks, the possible role of menthol in smokers' response to pharmacotherapy has not been well-studied. This study examined the effects of menthol on the pharmacokinetic (PK) profiles of bupropion and its principal metabolites, hydroxybupropion, threohydrobupropion, and erythrohydrobupropion among Black smokers. METHODS: After a 7-day placebo run-in period, participants received 150 mg bid sustained-release bupropion for 20-25 days. Blood samples were drawn for PK analysis on 2 occasions, 10-15 days after the commencement of bupropion while participants were still smoking (smoking phase) and at days 20-25 when they were asked not to smoke (nonsmoking phase). RESULTS: 18 smokers of nonmenthol cigarettes and 23 smokers of menthol cigarettes were enrolled in this study. No differences were found by menthol smoking status in the Cmax and area under the plasma concentration versus time curve (AUC) of bupropion and its metabolites in the smoking or nonsmoking phases. However, among menthol smokers, the AUC ratios of metabolite/bupropion were lower in the nonsmoking phase compared with the smoking phase (hydro/bup = 31.49 ± 18.84 vs. 22.95 ± 13.27, p = .04; erythro/bup = 1.99 ± 1.02 vs. 1.76 ± 0.75, p = .016; threo/bup = 11.77 ± 8.90 vs. 10.44 ± 5.63, p = .034). No significant differences were found in the metabolite/bup ratios between smoking and nonsmoking conditions among nonmenthol smokers. CONCLUSIONS: We did not find a significant effect of menthol compared with nonmenthol cigarette smoking on the PKs of bupropion and metabolites at steady state. More research is needed to advance the understanding of mechanisms underlying disparities in smoking cessation outcomes related to smoking of menthol cigarettes.

RESUMO

BACKGROUND: African-Americans remain underrepresented in clinical research despite experiencing a higher burden of disease compared to all other ethnic groups in the United States. The purpose of this article is to describe the study design and discuss strategies used to recruit and retain African-American smokers in a pharmacokinetic study. METHODS: The parent study was designed to evaluate the differences in the steady-state concentrations of bupropion and its three principal metabolites between African-American menthol and non-menthol cigarette smokers. Study participation consisted of four visits at a General Clinical Research Center (GCRC) over six weeks. After meeting telephone eligibility requirements, phone-eligible participants underwent additional screening during the first two GCRC visits. The last two visits (pharmacokinetic study phase) required repeated blood draws using an intravenous catheter over the course of 12 hours. RESULTS: Five hundred and fifteen African-American smokers completed telephone screening; 187 were phone-eligible and 92 were scheduled for the first GCRC visit. Of the 81 who attended the first visit, 48 individuals were enrolled in the pharmacokinetic study, and a total of 40 individuals completed the study (83% retention rate). CONCLUSIONS: Although recruitment of African-American smokers into a non-treatment, pharmacokinetic study poses challenges, retention is feasible. The results provide valuable information for investigators embarking on non-treatment laboratory-based studies among minority populations.

RESUMO

Low-density lipoprotein (LDL) apheresis, a treatment for familial hypercholesterolemia, significantly decreases LDL cholesterol and inflammatory markers such as C-reactive protein, CD40 ligand, and tissue factor. LDL apheresis also decreases high-density lipoprotein (HDL) cholesterol, which might be considered therapeutically counterproductive because HDL is known to be anti-inflammatory. However, recent studies have shown that HDL also possesses proinflammatory properties, as seen in its ability to alter LDL-induced monocyte chemotactic activity. We examined the acute effects of LDL apheresis on inflammatory HDL activity in 13 patients with familial hypercholesterolemia and cardiovascular disease who had been receiving bi-weekly LDL apheresis treatments. Immediately before and immediately after treatment, each patient's plasma was collected for analysis of inflammatory HDL and full lipid profile. LDL apheresis reduced LDL by 52% (from 208 +/- 89 to 99 +/- 48 mg/dl, p <0.002), and HDL decreased by 16% (49 +/- 15 to 41 +/- 13 mg/dl, p <0.003). At the same time, inflammatory HDL activity (in migrated monocytes per high-power field) decreased from 22 +/- 4 to 14 +/- 2, a 37% acute reduction (p <0.003). Moreover, inflammatory HDL before HDL apheresis was highly correlated with its acute reduction (r(s) = 0.85, p <0.001). In conclusion, our findings indicate that, in addition to decreasing LDL, LDL apheresis also decreases inflammatory HDL. The clinical significance of reducing inflammatory HDL is currently unknown, and further research is needed to examine its potential benefit for cardiovascular disease.

RESUMO

Patients with hereditary retinoblastoma have a heightened risk of developing subsequent bone and soft tissue sarcomas, exacerbated by radiation and alkylating chemotherapy. Secondary leiomyosarcomas are rare. A 29-year-old patient with bilateral retinoblastoma history presented with concurrent, independent malignancies found to be Rb-suppressed uterine and Rb-positive bladder leiomyosarcomas. She had undergone both ifosfamide chemotherapy and radiation therapy but demonstrated rare simultaneous primary leiomyosarcomas not previously described in association with ifosfamide. This rare case underlines the protean genetic predisposition to malignancy in this patient population, heightening awareness of lifelong malignancy potential, and the necessity for continuous periodic screening.
