Background: A relative dearth of literature exists on preferences of young gay male patients have regarding the sexual orientation and gender identity (SOGI) of their healthcare providers. Further research in this area is warranted to better serve the young MSM population.
Method(s): Data collection: A sample of 800 young adult gay men completed a brief survey on healthcare preferences between 2015-2016. Participant inclusion criteria were: age 18-29, male gender, self-identified gay sexual orientation, living in US for 5+ years, and being a resident of the New York City metropolitan area. Only participants who reported having a current PCP provided information on preferred PCP characteristics (i.e. male and/or LGBT). Data analysis: Multivariable logistic regression models were built to assess factors associated with participant preference for an LGBT or male PCP. Covariates for inclusion were considered based on prior literature as well as those identified as significant in bivariate logistic regression analyses. Backward model selection with variance inflation factor (VIF) analysis was used to eliminate collinearity and arrive at the most parsimonious models.
Result(s): In this sample, n=614 men (77%) reported having a PCP. Of those 614 with a PCP, 42% indicated a preference for male PCP, 36% preferred a gay or LGBT PCP, and a total of 20% preferred a male-LGBT provider. A preference for consolidated care and distrust in the health system were associated with preference for a sexual orientation concordant PCP. Preference for sexual orientation concordance was strongly associated with preference for gender concordance, and vice versa. Minority race was also found to be associated with preference for a gender-identity concordant (male) PCP.
Conclusion(s): Gay men who wish to discuss their overall health and sexual health with their primary care provider (ie, receive consolidated care) tend to prefer a LGBT provider. This is also true of gay men who distrust the healthcare system, possibly because they anticipate these providers will provide more culturally sensitive care. A surprising association was found between minority racial Background and preference for a gender concordant provider. Further research is warranted to explore the factors giving rise to this finding

BACKGROUND:The Society of Cardiovascular Computed Tomography (SCCT) recommends consideration of coronary artery calcium (CAC) scoring among individuals with a family history (FH) of coronary heart disease (CHD) and atherosclerotic cardiovascular disease (ASCVD) risk <5%. No dedicated study has examined the prognostic significance of CAC scoring among this population. METHODS:The CAC Consortium is a multi-center observational cohort study from four clinical centers linked to long-term follow-up for cause-specific mortality. All CAC scans were physician referred and performed in patients without a history of CHD. Our analysis includes 14,169 patients with ASCVD scores <5% and self-reported FH of CHD. RESULTS:This cohort had a mean age of 48.1 (SD 7.4), was 91.3% white, 47.4% female, had an average ASCVD score of 2.3% (SD 1.3), and 59.4% had a CAC = 0. The event rate for all-cause mortality was 1.2 per 1000 person-years, 0.3 per 1000 person-years for CVD-specific mortality, and 0.2 per 1000 person-years for CHD-specific mortality. In multivariable Cox proportional hazard models, those with CAC>100 had a 2.2 (95% CI 1.5-3.3) higher risk of all-cause mortality, 4.3 (95% CI 1.9-9.5) times higher risk of CVD-specific mortality, and a 10.4 (95% CI 3.2-33.7) times higher risk of CHD-specific mortality compared to individuals with CAC = 0. The NNS to detect CAC >100 in this sample was 9. CONCLUSION/CONCLUSIONS:In otherwise low risk patients with FH of CHD, CAC>100 were associated with increased risk of all-cause and CHD mortality with event rates in a range that may benefit with preventive pharmacotherapy. These data strongly support new SCCT recommendations regarding testing of patients with a family history of CHD.

Learning Objective #1: Recognize methemoglobinemia & its sequelae Learning Objective #2: Recall medications that confer risk of iatrogenic methemoglobinemia & treatment CASE: An 89-year-old woman was admitted with abdominal discomfort plus five days of dysuria and urinary frequency. Previously, she had seen a urologist for chronic dysuria and was prescribed estrogen cream for vaginal atrophy. On admission, her vital signs were notable for oxygen saturation of 88%, unresponsive to oxygen supplementation. Other clinical findings included jaundice, right upper quadrant and suprapubic tenderness, anemia (hemoglobin 8 g/dL), serum creatinine 2. 2 mg/dL, unremarkable liver function testing and ultrasound imaging, plus a uri-nalysis consistent with a urinary tract infection (UTI). Her chest X-ray was unremarkable and an arterial blood gas (ABG) obtained off of oxygen demonstrated normal partial pressure of oxygen (PaO2). Given the discrepancy between oxygen saturation on pulse oximetry and PaO2, met-hemoglobinemia was suspected. Co-oximetry revealed oxyhemoglobin 70%, methemoglobin > 21%. The patient denied recent benzocaine, nitrates, or dapsone use, but eventually disclosed taking phenazopyridine for several weeks prior to admission. Intravenous methylene blue was administered, ceftriaxone was given for her UTI, and supportive care was provided until her clinical status returned to baseline. IMPACT/DISCUSSION: Methemoglobinemia, a condition whereby functional anemia and tissue hypoxia are precipitated by acutely elevated methemoglobin concentration, is often iatrogenic. Nonspecific symptoms plus anemia and acute kidney injury (AKI) can be mistaken for many ailments, highlighting the importance of thorough medication review and having a high index of suspicion when there is a recent use of medications such as oxidizing agents (e.g. topical anesthetics, dapsone), nitrates, phenytoin, or antimalar-ials. The pathophysiology of acute respiratory distress in methemo-globinemia relates to the reduced erythrocyte oxygen-carrying capacity of functionally impaired hemoglobin. Skin discoloration, he-molytic anemia, and AKI have also been associated with phenazopyridine toxicity. The pathophysiology of AKI is still being investigated but may be multifactorial, including renal tubular epithelial cell injury, heme pigment-induced nephropathy from hemo-lytic anemia, and hypoxic injury from methemoglobinemia itself.
Conclusion(s): Methemolglobinemia presents with non-specific symptoms (e.g. headache, dizziness, dyspnea, fatigue, mental status changes). When a patient exhibits hypoxia unresponsive to supplemental oxygen, chocolate-brown hued arterial blood, and a discrepancy between pulse oximetry and ABG, methemoglobinemia should be at the top of one's differential. History-taking should include a thorough medication review (including over-the-counter agents) and chemical exposures. Once the diagnosis is confirmed with co-oximetry, methylene blue and supplemental oxygen should be given when methemoglobin level is greater than 20%

Background: Emergency department (ED) care decisions often hinge on the result of a diagnostic test. Frequently there is a lag time between a test result becoming available for review, and physician decision-making based on that result. Push notifications to physician smartphones have demonstrated improvement in this lag time in chest pain patients, but have not been studied in other ED patients. We implemented a system by which ED providers can subscribe to electronic alerts when test results are available for review via a smartphone or smartwatch push notification, and hypothesized that this would reduce the time to make clinical decisions. Method(s): This was a retrospective, multicenter, observational study in three emergency departments of an urban health system. We assessed push notification impact on time to disposition or time to follow-up order in six clinical scenarios of interest: chest x-ray (CXR) to disposition, basic metabolic panel (BMP) to disposition, urinalysis (UA) to disposition, respiratory pathogen panel (RPP) to disposition, hemoglobin (Hb) to blood transfusion order, and D-dimer to computed tomography pulmonary angiography (CTPA) order. All adult ED patients during a one-year period of push notification availability were included in the study. The primary outcome was median time from result availability to disposition order or defined follow-up order. Median times with interquartile ranges were determined in each scenario and the Mann Whitney (Wilcoxon) test for unpaired data was used to determine statistical significance. Result(s): During the study period there were 6,115 push notifications from 4,183 eligible ED encounters (2.7% of all ED encounters). All six scenarios studied were associated with a decrease in median time from test result availability to patient disposition, or from test result availability to follow-up order, when push notifications were employed: CXR to disposition (24 minutes, p<0.01), BMP to disposition (12 minutes, p<0.01), UA to disposition (50 minutes, p<0.01), RPP to disposition (43 minutes, p<0.01), D-dimer to CTPA (8 minutes, p<0.01), Hb to blood transfusion (19 minutes, p=0.73). Conclusion(s): Implementation of a push notification system for test result availability in the ED was associated with a decrease in lag time between test result availability and physician decision-making

Autism spectrum disorder (ASD) is a disorder affecting communication, with behaviors such as hyporesponsiveness to stimuli. When coupled with a lower threshold for allergic reactions, it can lead to a delayed identification of life-threatening anaphylaxis. It can also delay treatment for lesser complications such as with our patient, who developed a pruritic, erythematous rash as direct causation from piperacillin-tazobactam. This case addresses the delays in clinical care when approaching the administration of new medication in patients affected by autism.

(1) Background: Fasting during Ramadan involves large changes in daily eating patterns which strongly impacts the daily biorhythm and challenges the regular function of the digestive tract. The aim of this study was to assess satiety, bowel habits, body composition, blood glycaemia, and blood lipidemia after the consumption of high fiber cereal at dawn (Sohor) during the month of Ramadan; (2) Methods: A two-arm randomized, controlled, single-blinded, parallel-design study was conducted in Ramadan month. Participants were randomized to consume either 90 g of high fiber cereal (11 g fiber/90 g) at Sohor for 20 consecutive days (intervention group, n = 45) or to maintain their habitual diet intake (control group; n = 36); (3) Results: The intervention group reported higher satiety rating scores, improved bowel habits and reduced bloating frequency after the 20-day intervention. Significantly higher intake of carbohydrates and dietary fiber were observed in the intervention group. Total cholesterol and low density lipoprotein (LDL) cholesterol were significantly lower among the intervention group compared to the control group (p-value = 0.043, and p-value = 0.033, respectively) at the end of the intervention. No significant differences in body weight, body fat percentage, waist circumference, body mass index, blood glucose, high density lipoprotein (HDL) cholesterol, and triglycerides were observed between the two groups; (4) Conclusions: Consuming high fiber cereal had a positive effect on health and well-being during the month of Ramadan with better satiety, improved bowel functions, and improved blood lipids.

Right ventricular dysfunction is highly prevalent across cardiopulmonary diseases and independently predicts death in both heart failure (HF) and pulmonary hypertension (PH). Progression towards right ventricular failure (RVF) can occur in spite of optimal medical treatment of HF or PH, highlighting current insufficient understanding of RVF molecular pathophysiology. To identify molecular mechanisms that may distinctly underlie RVF, we investigated the cardiac ventricular transcriptome of advanced HF patients, with and without RVF. Using an integrated systems genomic and functional biology approach, we identified an RVF-specific gene module, for which WIPI1 served as a hub and HSPB6 and MAP4 as drivers, and confirmed the ventricular specificity of Wipi1, Hspb6, and Map4 transcriptional changes in adult murine models of pressure overload induced RV- versus LV- failure. We uncovered a shift towards non-canonical autophagy in the failing RV that correlated with RV-specific Wipi1 upregulation. In vitro siRNA silencing of Wipi1 in neonatal rat ventricular myocytes limited non-canonical autophagy and blunted aldosterone-induced mitochondrial superoxide levels. Our findings suggest that Wipi1 regulates mitochondrial oxidative signaling and non-canonical autophagy in cardiac myocytes. Together with our human transcriptomic analysis and corroborating studies in an RVF mouse model, these data render Wipi1 a potential target for RV-directed HF therapy.

OBJECTIVES/OBJECTIVE:Although the population of older adults is rising, the number of physicians seeking geriatrics training is decreasing. This study of fellows in geriatrics training programs across the United States explored motivating factors that led fellows to pursue geriatrics in order to inform recruitment efforts. DESIGN/METHODS:Semi-structured telephone interviews with geriatrics fellows. SETTING/METHODS:Academic medical centers. PARTICIPANTS/METHODS:Fifteen geriatrics fellows from academic medical centers across the United States. MEASUREMENTS/METHODS:This qualitative telephone study involved interviews that were transcribed and descriptively coded by two independent reviewers. A thematic analysis of the codes was summarized. RESULTS:Fellows revealed that mentorship and early exposure to geriatrics were the most influential factors affecting career choice. CONCLUSION/CONCLUSIONS:The results of this study have the potential for a large impact, helping to inform best practices in encouraging trainees to enter the field, and enhancing medical student and resident exposure to geriatrics.

BACKGROUND:Clinical decision support (CDS) has been shown to improve compliance with evidence-based care, but its impact is often diminished because of issues such as poor usability, insufficient integration into workflow, and alert fatigue. Noninterruptive CDS may be less subject to alert fatigue, but there has been little assessment of its usability. OBJECTIVE:This study aimed to study the usability of interruptive and noninterruptive versions of a CDS. METHODS:We conducted a usability study of a CDS tool that recommended prescribing an angiotensin-converting enzyme inhibitor for inpatients with heart failure. We developed 2 versions of the CDS: an interruptive alert triggered at order entry and a noninterruptive alert listed in the sidebar of the electronic health record screen. Inpatient providers were recruited and randomly assigned to use the interruptive alert followed by the noninterruptive alert or vice versa in a laboratory setting. We asked providers to "think aloud" while using the CDS and then conducted a brief semistructured interview about usability. We used a constant comparative analysis informed by the CDS Five Rights framework to analyze usability testing. RESULTS:A total of 12 providers participated in usability testing. Providers noted that the interruptive alert was readily noticed but generally impeded workflow. The noninterruptive alert was felt to be less annoying but had lower visibility, which might reduce engagement. Provider role seemed to influence preferences; for instance, some providers who had more global responsibility for patients seemed to prefer the noninterruptive alert, whereas more task-oriented providers generally preferred the interruptive alert. CONCLUSIONS:Providers expressed trade-offs between impeding workflow and improving visibility with interruptive and noninterruptive versions of a CDS. In addition, 2 potential approaches to effective CDS may include targeting alerts by provider role or supplementing a noninterruptive alert with an occasional, well-timed interruptive alert.
