AbstractIntroductionPhosphatidylethanol (PEth) is a long‐term marker of alcohol consumption used frequently in clinical scenarios such as liver transplant evaluation. Recent cases have demonstrated that packed red blood cell (pRBC) transfusion creates the potential for artificial elevation or decrease of observed PEth concentrations in recipients. Very little is known about the prevalence or stability of PEth in pRBCs.MethodsApheresis and whole‐blood (WB) donations were tested for PEth using liquid chromatography – tandem mass spectrometry with limit of quantitation 10 ng/mL. Units were stored under routine blood bank conditions to evaluate the stability of PEth and the impact of irradiation.ResultsOver 40% of apheresis and WB donors had PEth ≥10 ng/mL (maximum observed 587 ng/mL). As WB units were processed into component pRBCs, PEth concentrations increased and were higher than donor WB levels (EDTA sample) prior to collection (maximum observed 711 ng/mL). Storage for up to 5 weeks post donation resulted in mean 17.3% decrease in PEth‐positive units; in contrast to a prior report, we observed no PEth formation in units with negative (<10 ng/mL) baseline concentrations. Irradiation of pRBCs did not substantially affect PEth concentrations in either PEth‐positive or PEth‐negative units.DiscussionPEth concentrations in healthy blood donors may potentially confound alcohol use or abstinence assessment in pRBC recipients. Transfusion medicine services and clinical practices such as transplantation and behavioral medicine should recognize this phenomenon and collaborate on testing protocols to appropriately interpret PEth in pRBC recipients.

Objective To examine the impact of increased body mass index (BMI) on (1) tracheotomy timing and (2) short‐term surgical complications requiring a return to the operating room and 30‐day mortality utilizing data from the Multi‐Institutional Study on Tracheotomy (MIST). Methods A retrospective analysis of patients from the MIST database who underwent surgical or percutaneous tracheotomy between 2013 and 2016 at eight institutions was completed. Unadjusted and adjusted logistic regression analyses were used to assess the impact of obesity on tracheotomy timing and complications. Results Among the 3369 patients who underwent tracheotomy, 41.0% were obese and 21.6% were morbidly obese. BMI was associated with higher rates of prolonged intubation prior to tracheotomy accounting for comorbidities, indication for tracheotomy, institution, and type of tracheostomy ( p = 0.001). Morbidly obese patients (BMI ≥35 kg/m 2 ) experienced a longer duration of intubation compared with patients with a normal BMI (median days intubated [IQR 25%–75%]: 11.0 days [7–17 days] versus 9.0 days [5–14 days]; p < 0.001) but did not have statistically higher rates of return to the operating room within 30 days ( p = 0.12) or mortality ( p = 0.90) on multivariable analysis. This same finding of prolonged intubation was not seen in overweight, nonobese patients when compared with normal BMI patients (median days intubated [IQR 25%–75%]: 10.0 days [6–15 days] versus 10.0 days [6–15 days]; p = 0.36). Conclusion BMI was associated with increased duration of intubation prior to tracheotomy. Although morbidly obese patients had a longer duration of intubation, there were no differences in return to the operating room or mortality within 30 days.

Abstract Background Inflammatory bowel disease (IBD)–associated peripheral spondyloarthritis (pSpA) decreases quality of life and remains poorly understood. Given the prevalence of this condition and its negative impact, it is surprising that evidence-based disease definitions and diagnostic strategies are lacking. This systematic review summarizes available data to facilitate development and validation of diagnostics, patient-reported outcomes, and imaging indices specific to this condition. Methods A literature search was conducted. Consensus or classification criteria, case series, cross-sectional studies, cohort studies, and randomized controlled trials related to diagnosis were included. Results A total of 44 studies reporting data on approximately 1500 patients with pSpA were eligible for analysis. Data quality across studies was only graded as fair to good. Due to large heterogeneity, meta-analysis was not possible. The majority of studies incorporated patient-reported outcomes and a physical examination. A total of 13 studies proposed or validated screening tools, consensus, classification, or consensus criteria. A total of 28 studies assessed the role of laboratory tests, none of which were considered sufficiently accurate for use in diagnosis. A total of 17 studies assessed the role of imaging, with the available literature insufficient to fully endorse any imaging modality as a robust diagnostic tool. Conclusions This review highlights existing inconsistency and lack of a clear diagnostic approach for IBD-associated pSpA. Given the absence of an evidence-based approach, a combination of existing criteria and physician assessment should be utilized. To address this issue comprehensively, our future efforts will be directed toward pursuit of a multidisciplinary approach aimed at standardizing evaluation and diagnosis of IBD-associated pSpA.

Abstract Cardiac sarcoidosis (CS) is a form of inflammatory cardiomyopathy associated with significant clinical complications such as high-degree atrioventricular block, ventricular tachycardia, and heart failure as well as sudden cardiac death. It is therefore important to provide an expert consensus statement summarizing the role of different available diagnostic tools and emphasizing the importance of a multidisciplinary approach. By integrating clinical information and the results of diagnostic tests, an accurate, validated, and timely diagnosis can be made, while alternative diagnoses can be reasonably excluded. This clinical expert consensus statement reviews the evidence on the management of different CS manifestations and provides advice to practicing clinicians in the field on the role of immunosuppression and the treatment of cardiac complications based on limited published data and the experience of international CS experts. The monitoring and risk stratification of patients with CS is also covered, while controversies and future research needs are explored.

Purpose: Lucid episodes (LEs: unexpected episodes of spontaneous, meaningful, and relevant communication or behavior) in Alzheimer disease and related dementias are a new area of scientific inquiry that lacks clinical consensus and require more conceptual attention. Methods: We aimed to measure consensus from an expert group on: (1) potential medical or clinical explanations for LEs; (2) necessary medical and clinical context to LEs; and (3) interpretation of LEs. Patients: We convened 13 experts from different disciplines (neurology, psychiatry, psychology, pharmacy, palliative care, hospice, nursing, social work, primary care, geriatrics, and professional home caregivers) to identify elements of LEs. Results: Experts provided a range of opinions on medical and clinical explanations and questions to understand LEs. Consensus on LEs when presented with clinical vignettes was not reached. Panelists highlighted key medical and contextual factors needed to make a definitive judgement about LEs. Conclusion: There is variability in how LEs are interpreted by clinical experts, which complicates the identification of LEs in Alzheimer disease and related dementias.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Non–Small Cell Lung Cancer (NSCLC) provide recommendations for the treatment of patients with NSCLC, including diagnosis, primary disease management, surveillance for relapse, and subsequent treatment. The panel has updated the list of recommended targeted therapies based on recent FDA approvals and clinical data. This selection from the NCCN Guidelines for NSCLC focuses on treatment recommendations for advanced or metastatic NSCLC with actionable molecular biomarkers.

Objective Social determinants of health (SDoH) likely contribute to outcome disparities in lupus nephritis (LN). Understanding the overall burden and contribution of each domain could guide future health equity–focused interventions to improve outcomes and reduce disparities in LN. Objectives of this meta‐analysis were to 1) determine the association of overall SDoH and specific SDoH domains on LN outcomes and 2) develop a framework for the multidimensional impact of SDoH on LN outcomes. Methods We performed a comprehensive search of studies measuring associations between SDoH and LN outcomes. We examined pooled odds of poor LN outcomes including death, end‐stage kidney disease, or cardiovascular disease in patients with and without adverse SDoH. Additionally, we calculated the pooled odds ratios of outcomes by four SDoH domains: individual (eg, insurance), health care (eg, fragmented care), community (eg, neighborhood socioeconomic status), and health behaviors (eg, smoking). Results Among 531 screened studies, 31 meeting inclusion criteria and 13 with raw data were included in meta‐analysis. Pooled odds of poor outcomes were 1.47‐fold higher in patients with any adverse SDoH. Patients with adverse SDoH in individual and health care domains had 1.64‐fold and 1.77‐fold higher odds of poor outcomes. We found a multiplicative impact of having two or more adverse SDoH on LN outcomes. Black patients with public insurance and fragmented care had 12‐fold higher odds of poor LN outcomes. Conclusion Adverse SDoH is associated with poor LN outcomes. Having two or more adverse SDoH, specifically in different SDoH domains, had a multiplicative impact leading to worse LN outcomes, widening disparities. image

Abstract There has been an increase in volume as well as an improvement in overall survival (OS) after hematopoietic cell transplantation (HCT) for hematologic disorders. It is unknown if these changes have affected racial/ethnic minorities equally. In this observational study from the Center for International Blood and Marrow Transplant Research of 79 904 autologous (auto) and 65 662 allogeneic (allo) HCTs, we examined the volume and rates of change of autoHCT and alloHCT over time and trends in OS in 4 racial/ethnic groups: non-Hispanic Whites (NHWs), non-Hispanic African Americans (NHAAs), and Hispanics across 5 2-year cohorts from 2009 to 2018. Rates of change were compared using Poisson model. Adjusted and unadjusted Cox proportional hazards models examined trends in mortality in the 4 racial/ethnic groups over 5 study time periods. The rates of increase in volume were significantly higher for Hispanics and NHAAs vs NHW for both autoHCT and alloHCT. Adjusted overall mortality after autoHCT was comparable across all racial/ethnic groups. NHAA adults (hazard ratio [HR] 1.13; 95% confidence interval [CI] 1.04-1.22; P = .004) and pediatric patients (HR 1.62; 95% CI 1.3-2.03; P &lt; .001) had a higher risk of mortality after alloHCT than NHWs. Improvement in OS over time was seen in all 4 groups after both autoHCT and alloHCT. Our study shows the rate of change for the use of autoHCT and alloHCT is higher in NHAAs and Hispanics than in NHWs. Survival after autoHCT and alloHCT improved over time; however, NHAAs have worse OS after alloHCT, which has persisted. Continued efforts are needed to mitigate disparities for patients requiring alloHCT.

Introduction: Obesity is a known risk factor and causes worse cardiovascular outcomes in obstructive sleep apnea. With the growing use of cannabis in the US, so we aimed to assess the impact of cannabis use disorder (CUD) on risk of atrial tachyarrhythmias (atrial fibrillation, AF; atrial fibrillation, AFL) and stroke in young patients with obesity-associated obstructive sleep apnea (OOSA). Methods: The National Inpatient Sample (2015Oct-2017) with relevant ICD-10 codes were used to identify admissions among young adults (18-44 years) with OOSA. We then matched (1:1) two cohorts of cannabis use disorder (CUD+) vs. without (CUD-) with controlling potential sociodemographic confounders. Primary outcomes of interest were frequency and risk of atrial tachyarrhythmias and stroke assessed by multivariable analysis. Results: Of 7470 demographically-matched OOSA admissions, CUD+ and CUD- cohorts had 3735 hospitalizations in each cohort. Both cohorts were comparable mean age of 38 years and CUD+ cohort more frequently included male (66.6% vs. 53.5%), African American (40.0% vs. 30.1%) patients admitted non-electively (92.3% vs. 84.5%). Rates of drug abuse, hypertension, smoking and chronic pulmonary disease were higher but diabetes mellitus, hyperlipidemia, and renal failure were lower in CUD+ cohort vs. CUD- cohort (p<0.001). The frequency of AF/AFL (5.7% vs 7.4%) related admissions were lower; however, the risk of AF/AFL (OR:1.64, 95%CI:1.17-2.30, p=0.004) and stroke (OR:4.41, 95%CI:1.41-13.77, p<0.011) admissions were significantly higher in the OOSA-CUD+ cohort vs. CUD- cohort in the multivariable analysis controlled for relevant cardiovascular/extracardiac comorbidities and concomitant alcohol/drug abuse and smoking. Conclusions: This propensity-matched analysis highlights that recreational cannabis use in young patients with OOSA may alarmingly increase emergency hospitalizations and independently increase the risk of AF/AFL and stroke.
