RESUMO

PROBLEM: By 2055, the United States will no longer have a single race or ethnic majority. As the nation's demographics change, the field of medicine must also change to meet the needs of diverse patients. APPROACH: In 2013, UT Southwestern Medical Center implemented the Housestaff Emerging Academy of Leaders (HEAL) program, which provides leadership development skills and training to underrepresented in medicine physician residents in preparation for academic medicine careers. Program leaders hypothesized that by providing housestaff with structured mentorship, career coaching, and individualized development plans, HEAL would increase interest in pursuing academic careers and prepare residents for faculty positions. HEAL has since expanded to graduate medical education programs nationwide. OUTCOMES: From 2013 to 2018, HEAL included housestaff at UT Southwestern and other Texas medical centers, totaling 392 enrollees. In 2019, the program increased to include housestaff from around the country. The first HEAL USA program had 39 housestaff, which increased to 173 in 2019, including 60 faculty from 31 U.S. academic medical centers. The 2019 HEAL USA preassessment survey (32 trainee responses) revealed that 10 (31%) of the housestaff were "extremely interested" in academic medicine, but only 1 (3%) felt "extremely confident" to pursue an academic medicine career. Postassessment responses to these same items (5 trainee responses) were 3 (60%) and 1 (20%), respectively, with 3 (60%) also feeling "extremely prepared" (1 [20%]) or "very prepared" (2 [40%]) to pursue an academic medicine career. Of 70 evaluable participants who attended at least 2 sessions and have graduated from residency, 47 (67%) have attained academic faculty positions, whereas 23 (33%) have pursued positions at nonacademic centers. NEXT STEPS: The next steps for HEAL USA will be continued expansion to additional medical centers and effective delivery of career development and leadership training to encourage participants to pursue academic medical careers.

RESUMO

BACKGROUND: This retrospective study, conducted using the U.S. National Inpatient Sample (NIS), examines the outcomes and management of nonvariceal upper gastrointestinal bleeding (NVUGIB) in COVID-19 patients and identifies predictive factors to enhance patient prognosis. METHODS: We analyzed the 2020 U.S. NIS data involving adult patients (≥18 years) admitted with NVUGIB and categorized them based on the presence of COVID-19. Primary and secondary outcomes, NVUGIB-related procedures, and predictive factors were evaluated. RESULTS: Of 184,885 adult patients admitted with NVUGIB, 1.6% (2990) had COVID-19. Patients with NVUGIB and COVID-19 showed higher inpatient mortality, acute kidney injury, need for intensive care, and resource utilization metrics. Notably, there was a lower rate of early esophagogastroduodenoscopy (EGD). Multivariate logistic regression revealed conditions like peptic ulcer disease, mechanical ventilation, and alcohol abuse as significant positive predictors for NVUGIB in COVID-19 patients, whereas female gender and smoking were negative predictors. CONCLUSION: Our findings suggest that COVID-19 significantly increases the risk of mortality and complications in NVUGIB patients. The observed decrease in early EGD interventions, potentially contributing to higher mortality rates, calls for a review of treatment strategies. Further multicenter, prospective studies are needed to validate these results and improve patient care strategies.

RESUMO

In recent years, there have been multiple publications about the dearth of Black men in medicine. Appreciating the fact that underrepresented minority physicians disproportionately care for America's underserved communities, the lack of diversity in health care is particularly disturbing. Of imminent concern is the critical shortage of Black men doctors. In this Perspective, the authors contend that while mentoring is often considered among the most important strategies to increase the number of Black men in medicine, unique challenges in this demographic can diminish its effectiveness. Among these challenges are below average primary school educational experiences and a general mistrust of society on the part of Black men, as well as difficulties overcoming stereotypes and social biases that others hold against them. Furthermore, acknowledging that mentorship is paramount in achieving success in the medical field, the authors provide a framework to assist mentors in recognizing and addressing situations and obstacles that may disrupt the mentoring relationship and hinder its potential to best serve Black men pursuing advancement in medicine. This framework is represented by the acronym RACE: Reluctance to discuss race, Access to mentors, Cultural mistrust and racial concordance, and Empathy.

RESUMO

Aspirin (acetylsalicylic acid, ASA) can lead to gastrointestinal mucosal injury through disruption of its protective phospholipid bilayer. A liquid formulation of a novel pharmaceutical lipid-aspirin complex (PL-ASA) was designed to prevent this disruption. We sought to determine the pharmacokinetic (PK)/pharmacodynamic (PD) characteristics of PL-ASA compared with immediate release aspirin (IR-ASA). In this active-control crossover study, 32 healthy volunteers were randomized to receive 1 of 2 dose levels (a single dose of 325 mg or 650 mg) of either PL-ASA or IR-ASA. After a 2-week washout period between treatment assignments, subjects received a single dose of the alternative treatment, at the same dose level. The primary objectives of the study were to assess, for PL-ASA and IR-ASA at 325 mg and 650 mg dose levels, PK and PD bioequivalence, and safety, over a 24-h period after administration of both drugs. PK parameters were similar for PL-ASA and IR-ASA, and met FDA-criteria for bioequivalence. Regarding PD, both drugs also showed Cmin TxB2 values below 3.1 ng/mL (cut-off associated with decreased cardiovascular events) and > 99% inhibition of serum TxB2 ( ≥ 95% inhibition represents the cut-off for aspirin responders) along with similar results in several secondary PK/PD parameters. There were no serious adverse events or changes from baseline in vital signs or laboratory values in either of the 2 treatment groups. PL-ASA's novel liquid formulation has similar PK and PD performance compared with IR-ASA, supporting functional and clinical equivalence. These data coupled with the improved gastric safety of PL-ASA suggest that this novel formulation may exhibit an improved benefit-risk profile, warranting evaluation in future trials.Clinical trial registration: http://www.clinicaltrials.gov .

RESUMO

Objective: The efficacy and safety of oral lubiprostone for relieving symptoms of opioid-induced constipation (OIC) in patients with chronic noncancer pain were evaluated in a randomized, double-blind, placebo-controlled study. These data were also pooled with those from two similar phase 3 studies to explore the effects of methadone on treatment response. Methods: In the primary study, adults with OIC (fewer than three spontaneous bowel movements [SBMs] per week) were randomized to receive lubiprostone 24 mcg or placebo twice daily for 12 weeks. The primary end point was a change from baseline in the frequency of SBMs at week 8 in patients without a prior dose reduction. For the pooled analysis, the efficacy of lubiprostone was compared with placebo in patients receiving methadone or nonmethadone opioids. Responders were defined as patients with nine or more weeks of nonmissing SBM data who had one or more additional SBMs per week from baseline for each week that data were available and three or more SBMs per week for nine or more weeks. Results: In the primary study, the change from baseline at week 8 in SBM frequency was similar in the lubiprostone and placebo groups (P = 0.842). In the pooled analysis, the response rate was significantly higher with lubiprostone treatment vs placebo for patients receiving nonmethadone opioids (P = 0.002) but was similar between lubiprostone treatment and placebo in patients receiving methadone (P = 0.692). The safety profile of lubiprostone was unaffected by methadone use. Conclusions: The phase 3 study did not meet its primary efficacy end point. However, analysis of pooled data from all phase 3 studies in the OIC clinical development program, stratified by methadone opioid usage, confirmed that lubiprostone is effective for treatment of OIC in patients taking nonmethadone opioids; no safety concerns were identified based on the type of opioid used.

RESUMO

BACKGROUND: Lubiprostone is a ClC-2 chloride channel activator approved for the treatment of chronic idiopathic constipation (CIC) and opioid-induced constipation (OIC) in adults and irritable bowel syndrome with constipation (IBS-C) in women. Lubiprostone is generally well tolerated, with nausea being the most common adverse event. AIMS: To characterize nausea with lubiprostone using pooled results from clinical studies in patients with CIC, OIC, or IBS-C. METHODS: Data from three 3- and 4-week placebo-controlled studies and three long-term open-label studies were pooled for the CIC analysis. The OIC and IBS-C analyses each used pooled data from three 12-week placebo-controlled studies and one 36-week open-label extension study. RESULTS: The populations included the following numbers of patients: CIC, 316 (placebo) and 1113 (lubiprostone 24 mcg twice daily [BID]); OIC, 652 (placebo) and 889 (lubiprostone 24 mcg BID); and IBS-C, 435 (placebo) and 1011 (lubiprostone 8 mcg BID). The incidence of nausea in lubiprostone-treated patients ranged from 11.4 to 31.1%, with the highest incidence in patients with CIC. Among patients with any nausea, most reported only mild or moderate severity (96.5-99.1% across indications) and only one event (83.6-88.7%); most events occurred within the first 5 days of treatment. CONCLUSIONS: Nausea was the most common adverse event following the treatment with lubiprostone. Event rates varied by indication and dose, and the majority of nausea adverse events were mild to moderate in severity. Nausea events predominantly occurred early in the treatment period in all of the pooled study populations.

RESUMO

Background: Referring provider and endoscopist impressions of colonoscopy indication are used for clinical care, reimbursement, and quality reporting decisions; however, the accuracy of these impressions is unknown. This study assessed the sensitivity, specificity, positive and negative predictive value, and overall accuracy of methods to classify colonoscopy indication, including referring provider impression, endoscopist impression, and administrative algorithm compared with gold standard chart review. Methods: We randomly sampled 400 patients undergoing a colonoscopy at a Veterans Affairs health system between January 2010 and December 2010. Referring provider and endoscopist impressions of colonoscopy indication were compared with gold-standard chart review. Indications were classified into 4 mutually exclusive categories: diagnostic, surveillance, high-risk screening, or average-risk screening. Results: Of 400 colonoscopies, 26% were performed for average-risk screening, 7% for high-risk screening, 26% for surveillance, and 41% for diagnostic indications. Accuracy of referring provider and endoscopist impressions of colonoscopy indication were 87% and 84%, respectively, which were significantly higher than that of the administrative algorithm (45%; P<.001 for both). There was substantial agreement between endoscopist and referring provider impressions (κ=0.76). All 3 methods showed high sensitivity (>90%) for determining screening (vs nonscreening) indication, but specificity of the administrative algorithm was lower (40.3%) compared with referring provider (93.7%) and endoscopist (84.0%) impressions. Accuracy of endoscopist, but not referring provider, impression was lower in patients with a family history of colon cancer than in those without (65% vs 84%; P=.001). Conclusions: Referring provider and endoscopist impressions of colonoscopy indication are both accurate and may be useful data to incorporate into algorithms classifying colonoscopy indication.

RESUMO

BACKGROUND: A limitation of aspirin is that some patients, particularly those with diabetes, may not have an optimal antiplatelet effect. OBJECTIVES: The goal of this study was to determine if oral bioavailability mediates nonresponsiveness. METHODS: The rate and extent of serum thromboxane generation and aspirin pharmacokinetics were measured in 40 patients with diabetes in a randomized, single-blind, triple-crossover study. Patients were exposed to three 325-mg aspirin formulations: plain aspirin, PL2200 (a modified-release lipid-based aspirin), and a delayed-release enteric-coated (EC) aspirin. Onset of antiplatelet activity was determined by the rate and extent of inhibition of serum thromboxane B2 (TXB2) generation. Aspirin nonresponsiveness was defined as a level of residual serum TXB2 associated with elevated thrombotic risk (<99.0% inhibition or TXB2 >3.1 ng/ml) within 72 h after 3 daily aspirin doses. RESULTS: The rate of aspirin nonresponsiveness was 15.8%, 8.1%, and 52.8% for plain aspirin, PL2200, and EC aspirin, respectively (p < 0.001 for both comparisons vs. EC aspirin; p = 0.30 for comparison between plain aspirin and PL2200). Similarly, 56% of EC aspirin-treated subjects had serum TXB2 levels >3.1 ng/ml, compared with 18% and 11% of subjects after administration of plain aspirin and PL2200 (p < 0.0001). Compared with findings for plain aspirin and PL2200, this high rate of nonresponsiveness with EC aspirin was associated with lower exposure to acetylsalicylic acid (63% and 70% lower geometric mean maximum plasma concentration [Cmax] and 77% and 82% lower AUC0-t [area under the curve from time 0 to the last time measured]) and 66% and 72% lower maximum decrease of TXB2, with marked interindividual variability. CONCLUSIONS: A high proportion of patients treated with EC aspirin failed to achieve complete inhibition of TXB2 generation due to incomplete absorption. Reduced bioavailability may contribute to "aspirin resistance" in patients with diabetes.

RESUMO

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are some of the most commonly used medications worldwide. The availability of hundreds of products containing an NSAID, combined with a lack of recognition and understanding of NSAIDs, can increase the potential of consumers to inadvertently exceed the recommended NSAID dosage, which can cause potentially serious side effects. Physician and consumer education regarding the appropriate use of NSAIDs can help prevent NSAID misuse. Evaluations of current consumer patterns of NSAID use and perceptions about NSAIDs are necessary to develop targeted educational programs. MATERIALS AND METHODS: An online and telephone survey of 1,750 U.S. adults was conducted to obtain information about the patterns of use and perceptions about prescription and over-the-counter NSAIDs and medicines. The survey was compared to similar surveys conducted in 1997, 2001 and 2002. RESULTS: NSAIDs are widely used, with 63% of respondents reporting use within the past 12 months. NSAIDs were not well recognized by generic or brand names and many respondents were unaware or unconcerned about potential side effects. NSAID misuse was common, with 19% using more than the recommended dose and 24% using multiple NSAIDs concomitantly. NSAID use appears to have increased since 2002 but the level of NSAID awareness and pattern of NSAID misuse has not changed. CONCLUSIONS: NSAIDs are widely used and often used in a manner that increases the risk of serious side effects. Sufficient knowledge and understanding of NSAIDs is lacking and educational interventions directed to consumers and physicians are needed.

RESUMO

BACKGROUND: Proton-pump inhibitors (PPIs) have been demonstrated to reduce rates of gastrointestinal events in patients requiring dual antiplatelet therapy (DAPT). Data are limited regarding the efficacy and safety of PPIs in high-risk cardiovascular subsets after acute coronary syndrome or percutaneous coronary intervention. METHODS: All patients enrolled in COGENT (Clopidogrel and the Optimization of Gastrointestinal Events Trial) were initiated on DAPT (with aspirin and clopidogrel) for various indications within the prior 21 days. These post hoc analyses of the COGENT trial evaluated the efficacy and safety of omeprazole compared with placebo in subsets of patients requiring DAPT for the 2 most frequent indications: 1) patients undergoing percutaneous coronary intervention (for any indication) within 14 days of randomization (n = 2676; 71.2%); and 2) patients presenting with acute coronary syndrome managed with or without percutaneous coronary intervention (n = 1573; 41.8%). Unadjusted Cox proportional hazards models were used to estimate effect sizes through final follow-up. RESULTS: Median follow-up duration was 110 days (interquartile range 55-167). In percutaneous coronary intervention-treated patients, omeprazole significantly reduced rates of composite gastrointestinal events at 180 days (1.2% vs 2.7%; hazard ratio [HR] 0.43; 95% confidence interval [CI], 0.22-0.85; P = .02) without increasing composite cardiovascular events (5.4% vs 6.3%; HR 1.00; 95% CI, 0.67-1.50; P = 1.00). Similarly, omeprazole lowered risk of the primary gastrointestinal endpoint at 180 days in patients presenting with acute coronary syndrome (1.1% vs 2.7%; HR 0.37; 95% CI, 0.13-1.01; P = .05) without a significant excess in cardiovascular events (5.6% vs 4.5%; HR 1.40; 95% CI, 0.77-2.53; P = .27). CONCLUSIONS: PPI therapy attenuates gastrointestinal bleeding risk without significant excess in major cardiovascular events in high-risk cardiovascular subsets, regardless of indication for DAPT. Future studies will be needed to clarify optimal gastroprotective strategies for higher-intensity and longer durations of DAPT.
