Objective: To assess the performance of a lower predicted postoperative (ppo) forced expiratory volume in 1 second (FEV1) or diffusion capacity of the lung for carbon monoxide (DLCO) (ppo-FEV1/ppoDLCO) threshold to predict cardiopulmonary complications after minimally invasive surgery (MIS) lobectomy. Background: Although MIS is associated with better postoperative outcomes than open surgery, MIS uses risk-assessment algorithms developed for open surgery. Moreover, several different definitions of cardiopulmonary complications are used for assessment. Methods: All patients who underwent MIS lobectomy for clinical stage I to II lung cancer from 2018 to 2022 at our institution were considered. The performance of a ppoFEV1/ppoDLCO threshold of <45% was compared against that of the current guideline threshold of <60%. Three different definitions of cardiopulmonary complications were compared: Society of Thoracic Surgeons (STS), European Society of Thoracic Surgeons (ESTS), and Berry and colleagues' study. Results: In 946 patients, the ppoFEV1/ppoDLCO threshold of < 45% was associated with a higher proportion correctly classified [79% (95% CI, 76%-81%) vs 65% (95% CI, 62%-68%); P< 0.001]. The complication with the biggest difference in incidence between ppoFEV1/ppoDLCO of 45% to 60% and >60% was prolonged air leak [33 (13%) vs 34 (6%); P< 0.001]. The predicted probability curves for cardiopulmonary complications were higher for the STS definition than for the ESTS or Berry definitions across ppoFEV1 and ppoDLCO values. Conclusions: The ppoFEV1/ppoDLCO threshold of <45% more accurately classified patients for cardiopulmonary complications after MIS lobectomy, emphasizing the need for updated riskassessment guidelines for MIS lobectomy to optimize additional cardiopulmonary function evaluation.

BACKGROUND: Plaque quantification from coronary computed tomography angiography has emerged as a valuable predictor of cardiovascular risk. Deep learning can provide automated quantification of coronary plaque from computed tomography angiography. We determined per-patient age- and sex-specific distributions of deep learning--based plaque measurements and further evaluated their risk prediction for myocardial infarction in external samples. METHODS: In this international, multicenter study of 2803 patients, a previously validated deep learning system was used to quantify coronary plaque from computed tomography angiography. Age- and sex-specific distributions of coronary plaque volume were determined from 956 patients undergoing computed tomography angiography for stable coronary artery disease from 5 cohorts. Multicenter external samples were used to evaluate associations between coronary plaque percentiles and myocardial infarction. RESULTS: Quantitative deep learning plaque volumes increased with age and were higher in male patients. In the combined external sample (n=1847), patients in the ≥75th percentile of total plaque volume (unadjusted hazard ratio, 2.65 [95% CI, 1.47-4.78]; P=0.001) were at increased risk of myocardial infarction compared with patients below the 50th percentile. Similar relationships were seen for most plaque volumes and persisted in multivariable analyses adjusting for clinical characteristics, coronary artery calcium, stenosis, and plaque volume, with adjusted hazard ratios ranging from 2.38 to 2.50 for patients in the ≥75th percentile of total plaque volume. CONCLUSIONS: Per-patient age- and sex-specific distributions for deep learning--based coronary plaque volumes are strongly predictive of myocardial infarction, with the highest risk seen in patients with coronary plaque volumes in the ≥75th percentile.

BACKGROUND: Blood-brain barrier (BBB) integrity is presumed to be impaired in hypertension, resulting from cerebral endothelial dysfunction. Hypertension precedes various cerebrovascular diseases, such as cerebral small vessel disease, and is a risk factor for developing neurodegenerative diseases for which BBB disruption is a preceding pathophysiological process. In this cross-sectional study, we investigated the relation between hypertension, current blood pressure, and BBB leakage in human subjects. METHODS: BBB leakage was determined in 22 patients with hypertension and 19 age- and sex-matched normotensive controls (median age [range], 65 [45--80] years; 19 men) using a sparsely time-sampled contrast-enhanced 7T magnetic resonance imaging protocol. Structural cerebral small vessel disease markers were visually rated. Multivariable regression analyses, adjusted for age, sex, cardiovascular risk factors, and cerebral small vessel disease markers, were performed to determine the relation between hypertension status, systolic and diastolic blood pressure, mean arterial pressure, drug treatment, and BBB leakage. RESULTS: Both hypertensive and normotensive participants showed mild scores of cerebral small vessel disease. BBB leakage did not differ between hypertensive and normotensive participants; however, it was significantly higher for systolic blood pressure, diastolic blood pressure, and mean arterial pressure in the cortex, and diastolic blood pressure and mean arterial pressure in the gray matter. Effectively treated patients showed less BBB leakage than those with current hypertension. CONCLUSIONS: BBB integrity in the total and cortical gray matter decreases with increasing blood pressure but is not related to hypertension status. These findings show that BBB disruption already occurs with increasing blood pressure, before the presence of overt cerebral tissue damage. Additionally, our results suggest that effective antihypertensive medication has a protective effect on the BBB. [ABSTRACT FROM AUTHOR]

Introduction Letters of recommendation are considered an important factor in the holistic ranking of orthopaedic residency applications. The standardized letter of recommendation (SLOR) was introduced in 2017 in response to the inherent bias and limited comparative value of traditional LORs. It includes standardized questions about an applicant’s orthopaedic qualifications, designed to enable fair comparisons among candidates. However, disparate and inconsistent findings have made it difficult to draw meaningful conclusions from individual studies on the SLOR and narrative letter of recommendation. Question/purposes In this systematic review we asked: (1) What is the distribution of applicant SLOR rating among nine domains and summative scores? (2) Are there applicant characteristics associated with SLOR ratings? (3) Is there gender and racial bias in the SLOR and narrative letter of recommendation? Methods PubMed, EBSCO, and Google Scholar electronic databases were queried on March 20, 2023, to identify all studies evaluating SLOR and narrative letter of recommendations between January 1, 2017, and March 20, 2023. Articles that evaluated orthopaedic SLOR or narrative LORs were included. Systematic reviews, case reports, duplicate studies between databases, and grey literature such as abstracts and articles on preprint servers were excluded. Eight studies including 6179 applicants and 18,987 letters of recommendation were included in the final analysis. The applicant classes ranged from years 2014 to 2020. Two reviewers independently evaluated the quality of the included studies using the Joanna Briggs Institute (JBI) tool for cross-sectional studies. The mean JBI score of included studies was 7.4 out of a maximum of 8, with higher scores indicating better quality. The primary outcome was to determine the distribution of applicant SLOR rankings in their summative score. Summative scores were separated into ranked to match, top one-third, middle one-third, lower one-third, and not a fit. Four studies reported the summative SLOR scores of applicants. Our secondary study goal was to assess applicant characteristics associated with SLOR summative scores and assess any bias present in the SLOR or narrative recommendation. Five studies compared SLOR ratings across applicant characteristics including gender, race, USMLE Step 1 score, USMLE Step 2 score, Alpha Omega Alpha (AVA) membership, clerkship grades, and publications. Gender and racial bias were also assessed across five studies. Four studies utilized a linguistic analysis software to search letters of recommendation for differences in word category use by gender and race. Results Studies consistently found that a higher percentage of candidates were identified in the top percentile blocks than is mathematically possible. For example, the two studies that tallied the proportion of candidates ranking in the top 10% of applicants found that 36% and 42% were rated as being in the top 10%. Similarly, articles found more than 87% of applicants scored in the top one-third. Studies had mixed results, but in general, they suggested that AVA status, higher Step 1 scores, and more research publications have a slightly positive association with increased SLOR scores. We found no evidence of gender bias against women, and in fact, most studies evaluating word choices found word choices for women candidates generally were stronger. Similarly, no consistent disparities were identified in word categories utilized in SLORs based on applicant race. Conclusion Most notably, a mathematically impossible proportion of applicants were counted in the top percentiles in letters of recommendation. This compromises readers’ abilities to differentiate candidates. Factors like AOA status and research publications displayed a modest positive correlation with SLOR scores. Gender bias against women or candidates from racial minority groups was not evident. Clinical Relevance We suggest that group SLOR authorship, with a consensus assessment by clerkship or residency directors, should be considered. We also recommend the incorporation of mean and SD scores for each letter writer (or group) alongside their letters. Furthermore, studies indicate that submitting all four SLOR letters can substantially improve an applicant’s chances of success. We advise students to choose strategically and submit the maximum allowable number of SLORs. [ABSTRACT FROM AUTHOR]

Background: Design Thinking is gaining recognition as an innovative and creative approach to problem solving. Though nurse leaders need problem solving tools to address health care challenges, Design Thinking concepts are not commonly taught in nursing education. To introduce graduate level nursing students to Design Thinking, we held an educational activity focused on this content as part of required coursework. Purpose: The purpose was to describe and compare outcomes of a Design Thinking educational activity on students' perceived knowledge, confidence, and benefits to nursing practice. Methods: Graduate level nursing students participated in a 3-hour educational activity. After the session, students completed an anonymous 10-item survey of their perceptions of the educational activity. Results: Students reported increased knowledge and confidence of communication strategies and Design Thinking concepts that would benefit their practice. Conclusion: Nurse educators should include Design Thinking teaching and learning strategies in their programs. [ABSTRACT FROM AUTHOR]

Background: Understanding the trends and patterns of research funding can aid in enhancing growth and innovation in orthopaedic research. We sought to analyze financial trends in public orthopaedic surgery funding and characterize trends in private funding distribution among orthopaedic surgeons and hospitals to explore potential disparities across orthopaedic subspecialties. Methods: We conducted a cross-sectional analysis of private and public orthopaedic research funding from 2015 to 2021 using the Centers for Medicare & Medicaid Services Open Payments database and the National Institutes of Health (NIH) RePORTER through the Blue Ridge Institute for Medical Research, respectively. Institutions receiving funds from both the NIH and the private sector were classified separately as publicly funded and privately funded. Research payment characteristics were categorized according to their respective orthopaedic fellowship subspecialties. Descriptive statistics, Wilcoxon rank-sum tests, and Mann-Kendall tests were employed. A p value of <0.05 was considered significant. Results: Over the study period, $348,428,969 in private and $701,078,031 in public research payments were reported. There were 2,229 unique surgeons receiving funding at 906 different institutions. The data showed that a total of 2,154 male orthopaedic surgeons received $342,939,782 and 75 female orthopaedic surgeons received $5,489,187 from 198 different private entities. The difference in the median payment size between male and female orthopaedic surgeons was not significant. The top 1% of all practicing orthopaedic surgeons received 99% of all private funding in 2021. The top 20 publicly and top 20 privately funded institutions received 77% of the public and 37% of the private funding, respectively. Private funding was greatest (31.5%) for projects exploring adult reconstruction. Conclusion: While the amount of public research funding was more than double the amount of private research funding, the distribution of public research funding was concentrated in fewer institutions when compared with private research funding. This suggests the formation of orthopaedic centers of excellence (CoEs), which are programs that have high concentrations of talent and resources. Furthermore, the similar median payment by gender is indicative of equitable payment size. In the future, orthopaedic funding should follow a distribution model that aligns with the existing approach, giving priority to a nondiscriminatory stance regarding gender, and allocate funds toward CoEs. Clinical Relevance: Securing research funding is vital for driving innovation in orthopaedic surgery, which is crucial for enhancing clinical interventions. Thus, understanding the patterns and distribution of research funding can help orthopaedic surgeons tailor their future projects to better align with current funding trends, thereby increasing the likelihood of securing support for their work.

INTRODUCTION: Hepatic steatosis is highly prevalent in people living with HIV. It remains unclear whether HIV in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with greater risks of liver disease progression and cardiovascular disease (CVD). We aim to evaluate the impact of HIV infection on risks of liver and CVD outcomes among US Veterans with MASLD. METHODS: Using national Veterans Administration data from 2010 to 2022, we created a propensity score-matched cohort of MASLD patients with vs without HIV. Primary outcomes were incidence of cirrhosis and hepatocellular carcinoma (HCC) among patients with vs without HIV and patients with MASLD-HIV on antiretroviral therapy (ART) vs not on ART. Secondary outcomes included incidence of major adverse cardiovascular events and overall survival. RESULTS: The propensity-matched cohort included 920 MASLD patients with HIV and 920 MASLD patients without HIV and was similar in demographics and comorbidities. Compared with MASLD patients without HIV, incidences of cirrhosis and HCC were similar among MASLD with HIV. Compared with MASLD patients without HIV, incidence of major adverse cardiovascular event was higher among MASLD patients with HIV (5.18 vs 4.48 per 100 person-years, P = 0.03). Overall 5-year survival was significantly lower among MASLD patients with HIV and even lower among those not on ART. DISCUSSION: Among US Veterans with MASLD, concurrent HIV infection, and particularly not being on ART, is associated with greater risks of CVD and decreased overall survival. No differences in risks of cirrhosis or HCC were observed. [ABSTRACT FROM AUTHOR]

BACKGROUND: Misuse of prescription opioids is a well-established contributor to the US opioid epidemic. The primary objective of this study was to identify which level of care delivery (ie patient, prescriber, or hospital) produced the most unwarranted variation in opioid prescribing after common surgical procedures. STUDY DESIGN: Electronic health record data from a large multihospital healthcare system were used in conjunction with random-effect models to examine variation in opioid prescribing practices after similar inpatient and outpatient surgical procedures between October 2019 and September 2021. Unwarranted variation was conceptualized as variation resulting from prescriber behavior unsupported by evidence. Covariates identified as drivers of warranted variation included characteristics known to influence pain levels or patient safety. All other model variables, including prescriber specialty and patient race, ethnicity, and insurance status were characterized as potential drivers of unwarranted variation. RESULTS: Among 25,188 procedures with an opioid prescription at hospital discharge, 53.5% exceeded guideline recommendations, corresponding to 13,228 patients receiving the equivalent of >140,000 excess 5 mg oxycodone tablets after surgical procedures. Prescribing variation was primarily driven by prescriber-level factors, with approximately half of the total variation in morphine milligram equivalents prescribed observed at the prescriber level and not explained by any measured variables. Unwarranted covariates associated with higher prescribed opioid quantity included non-Hispanic Black race, Medicare insurance, smoking history, later hospital discharge times, and prescription by a surgeon rather than a hospitalist or primary care provider. CONCLUSIONS: Given the large proportion of unexplained variation observed at the provider level, targeting prescribers through education and training may be an effective strategy for reducing postoperative opioid prescribing.

BACKGROUND: Evidence suggests that drug-coated balloons may benefit in-stent restenosis (ISR) treatment. However, the efficacy of new-generation sirolimus-coated balloon (SCB) compared with the latest generation drug-eluting stents (DESs) has not been studied in this setting. METHODS: All patients in the EASTBORNE (The All-Comers Sirolimus-Coated Balloon European Registry) and DEB-DRAGON (DEB vs Thin-DES in DES-ISR: Long Term Outcomes) registries undergoing percutaneous coronary intervention for DESISR were included in the study. The primary study end point was target lesion revascularization at 24 months. Secondary end points were major adverse cardiovascular events, all-cause death, myocardial infarction, and target vessel revascularization at 24 months. Our goal was to evaluate the efficacy and safety of SCB versus thin-struts DES in ISR at long-term follow-up. RESULTS: A total of 1545 patients with 1679 ISR lesions were included in the pooled analysis, of whom 621 (40.2%) patients with 621 lesions were treated with thin-strut DES and 924 (59.8%) patients with 1045 lesions were treated with SCB. The unmatched cohort showed no differences in the incidence of target lesion revascularization (10.8% versus 11.8%; P=0.568); however, there was a trend toward lower rates of myocardial infarction (7.4% versus 5.0%; P=0.062) and major adverse cardiovascular events (20.8% versus 17.1%; P=0.072) in the SCB group. After propensity score matching (n=335 patients per group), there were no significant differences in the rates of target lesion revascularization (11.6% versus 11.8%; P=0.329), target vessel revascularization (14.0% versus 13.1%; P=0.822), myocardial infarction (7.2% versus 4.5%; P=0.186), all-cause death (5.7% versus 4.2%; P=0.476), and major adverse cardiovascular event (21.5% versus 17.6%; P=0.242) between DES and SCB treatment. CONCLUSIONS: In patients with ISR, angioplasty with SCB compared with thin-struts DES is associated with comparable rates of target lesion revascularization, target vessel revascularization, myocardial infarction, all-cause death, and major adverse cardiovascular events at 2 years.

INTRODUCTION: The aim of this study is to describe the presenting features, genetic factors, and outcomes of 23 adults who developed liver injury after coronavirus disease 2019 (COVID-19) mRNA vaccination. METHODS: Patients with suspected COVID-19 vaccine hepatitis were enrolled into the Drug-Induced Liver Injury Network. Causality was assessed using the Drug-Induced Liver Injury Network expert opinion score. High-resolution HLA sequencing was undertaken using Illumina platform. RESULTS: Amongst the 16 high causality cases, median time to onset was 16 days, median age was 63 years, and 75% were female. The injury was hepatocellular in 75% with a median alanine aminotransferase of 497 U/L, and 37% had jaundice. An antinuclear antibody and smooth muscle antibody were detectable in 27% and 36%, but only 12% had an elevated immunoglobulin G level. During follow-up, 37% received a short course of corticosteroids, and 88% fully recovered by 6 months with no deaths observed. HLA alleles associated with autoimmune hepatitis were not overrepresented compared with controls, but an ERAP-2 variant (rs1263907) and the ERAP-1 Hap6 haplotype were significantly overrepresented in the high causality cases vs controls (P = 0.026 and 5 x 10-5, respectively). DISCUSSION: Acute liver injury may arise within 8 weeks of COVID-19 mRNA vaccination that is generally mild and self-limited in most patients. The absence of an association with the AIH HLA alleles combined with the significant ERAP-2 and ERAP-1 Hap6 haplotype associations implicates a unique but very rare host immune response to vaccine-derived antigens in the pathogenesis of COVID-19 vaccine hepatotoxicity.

BACKGROUND: Increased hsCRP (high-sensitivity C-reactive protein), a marker of inflammation, is associated with incident cardiovascular events. We aim to determine whether the baseline or trajectory of hsCRP levels over time predicts incident heart failure (HF) hospitalization. METHODS: JHS (Jackson Heart Study) participants' (n=3920 Black adults) hsCRP levels were measured over 3 visits (from 2000 to 2013). We assessed the association of hsCRP at baseline (visit 1) with incident HF hospitalization using Cox proportional hazards models. Furthermore, we assessed the association of the trajectory of hsCRP over repeated measurements (visits 1-3) with incident HF using joint models. Hazard ratios are reflective of an increase in hsCRP by 1 SD on a log2 scale. We also assessed the association of change in hsCRP between visit 1 and visit 3 with Cox proportional hazards models by grouping patients by low (<2 mg/L) and high (=2 mg/L) hsCRP levels. The 4 groups were low-to-low (referent), low-to-high, high-to-low, and high-to-high. RESULTS: Mean baseline age of participants was 54±13 years, and 63.8% were women. Over a median follow-up of 12 years, 308 (7.9%) participants were hospitalized with incident HF. Baseline hsCRP was not associated with incident HF (adjusted hazard ratio, 1.08 [95% CI, 0.96-1.22]). However, increasing hsCRP levels over repeated measures were associated with a higher risk of incident HF overall (adjusted hazard ratio, 1.22 [95% CI, 1.03-1.44]) and HF with preserved ejection fraction (adjusted hazard ratio, 1.30 [95% CI, 1.02-1.65]) but not HF with reduced ejection fraction (P>0.05). Furthermore, changes in hsCRP from low-to-high and high-to-low levels were associated with incident HF (P<0.05). CONCLUSIONS: While baseline hsCRP was not associated with incident HF, an increasing trajectory of hsCRP over time was associated with increased risk for incident HF (particularly HF with preserved ejection fraction). Temporal change in hsCRP may be an important marker of risk for incident HF with preserved ejection fraction in Black adults. [ABSTRACT FROM AUTHOR]

Background: Rural hospitals are increasingly at risk of closure. Closure reduces the availability of hospital care in rural areas, resulting in a disparity in health between rural and urban citizens, and it has broader economic impacts on rural communities as rural hospitals are often large employers and are vital to recruiting new businesses to a community. To combat the risk of closure, rural hospitals have sought partnerships to bolster financial performance, which often results in a closure of services valuable to the community, such as obstetrics and certain diagnostic services, which are viewed as unprofitable. This can lead to poor health outcomes as community members are unable to access care in these areas. Purpose: In this article, we explore rural hospital service offerings and financial performance, with an aim to illuminate if specific service offerings are associated with positive financial performance in a rural setting. Methods: Our study used hospital organization data, as well as county-level demographics with periods of analysis from 2015 and 2019. We employed a pooled cross-sectional regression analysis with robust standard errors examining the association between total margin and service lines among rural hospitals in the United States. Results: The findings suggest that some services deemed unprofitable in urban and suburban hospital settings--such as obstetrics and drug/alcohol rehabilitation--are associated with higher margins in rural hospitals. Other unprofitable service lines--such as psychiatry and long-term care--are associated with lower margins in rural hospitals. Conclusion: Our results suggest the need of rural hospitals to choose services that align with environmental circumstances to maximize financial performance. Practice Implication: Hospital administrators in rural settings need to take a nuanced look at their environmental and organizational specifics when deciding upon the service mix. Generalizations regarding profitability should be avoided to maximize financial performance. [ABSTRACT FROM AUTHOR]
