Impact of Mental Health Treatment on Outcomes in Patients With Heart Failure and Ischemic Heart Disease.

BACKGROUND: There is conflicting evidence as to the impact of mental health treatment on outcomes in patients with heart disease. The aim of this study was to examine whether individuals who received mental health treatment for anxiety or depression after being hospitalized for ischemic disorders or heart failure had a reduced frequency of rehospitalizations, emergency department visits, or mortality compared with those who did not receive treatment. METHODS AND RESULTS: A population-based, retrospective, cohort design was used to examine the association between psychotherapy or antidepressant medication prescription and health service utilization and mortality in patients with coronary artery disease or heart failure and comorbid anxiety or depression. Those receiving versus not receiving mental health treatment were compared based on the frequency of rehospitalization, emergency department visits, and mortality. The study sample included 1563 patients who had a mean age of 50.1 years. Individuals who received both forms of mental health treatment for anxiety or depression were 75% less likely to be rehospitalized, 74% less likely to have an emergency department visit, and 66% less likely to die from any cause. CONCLUSIONS: Mental health treatment for anxiety or depression has a significant impact on outcomes in patients with cardiovascular disease consisting of reduced hospitalizations, emergency department visits, and in some conditions improved survival.

Impairment in quantitative microvascular function in non-ischemic cardiomyopathy as demonstrated using cardiovascular magnetic resonance.

BACKGROUND: Microvascular dysfunction (MVD) is present in various cardiovascular diseases and portends worse outcomes. We assessed the prevalence of MVD in patients with non-ischemic cardiomyopathy (NICM) as compared to subjects with preserved ejection fraction (EF) using stress cardiovascular magnetic resonance (CMR). METHODS: We retrospectively studied consecutive patients with NICM and 58 subjects with preserved left ventricular (LV) EF who underwent stress CMR between 2011-2016. MVD was defined visually as presence of a subendocardial perfusion defect and semiquantitatively by myocardial perfusion reserve index (MPRI<1.51). MPRI was compared between groups using univariate analysis and multivariable linear regression. RESULTS: In total, 41 patients with NICM (mean age 51 ± 14, 59% male) and 58 subjects with preserved LVEF (mean age 51 ± 13, 31% male) were identified. In the NICM group, MVD was present in 23 (56%) and 11 (27%) by semiquantitative and visual evaluation respectively. Compared to those with preserved LVEF, NICM patients had lower rest slope (3.9 vs 4.9, p = 0.05) and stress perfusion slope (8.8 vs 11.7, p<0.001), and MPRI (1.41 vs 1.74, p = 0.02). MPRI remained associated with NICM after controlling for age, gender, hypertension, ethnicity, diabetes, and late gadolinium enhancement (log MPR, ß coefficient = -0.19, p = 0.007). CONCLUSIONS: MVD-as assessed using CMR-is highly prevalent in NICM as compared to subjects with preserved LVEF even after controlling for covariates. Semiquantitative is able to detect a greater number of incidences of MVD compared to visual methods alone. Further studies are needed to determine whether treatment of MVD is beneficial in NICM.

A randomized, cross-over trial of metoprolol succinate formulations to evaluate PK and PD end points for therapeutic equivalence.

There are limited comparison data throughout the dosing interval for generic versus brand metoprolol extended-release (ER) tablets. We compared the pharmacokinetics (PKs) and pharmacodynamics of brand name versus two generic formulations (drugs 1 and 2) of metoprolol ER tablets with different time to maximum concentration (Tmax ) in adults with hypertension. Participants were randomized to equal drug doses (50-150 mg/day) administered in one of two sequences (brand-drug1-brand-drug2 or brand-drug2-brand-drug1) and completed 24-h PK, digital heart rate (HR), ambulatory blood pressure (BP), and HR studies after taking each formulation for greater than or equal to 7 days. Metoprolol concentrations were determined by liquid chromatography tandem mass spectrometry, with noncompartmental analysis performed to obtain PK parameters in Phoenix WinNonlin. Heart rate variability (HRV) low-to-high frequency ratio was determined per quartile over the 24-h period. Thirty-six participants completed studies with the brand name and at least one generic product. Among 30 participants on the 50 mg dose, the primary PK end points of area under the concentration-time curve and Cmax were similar between products; Tmax was 6.1 ± 3.6 for the brand versus 3.5 ± 4.9 for drug 1 (p = 0.019) and 9.6 ± 3.2 for drug 2 (p < 0.001). Among all 36 participants, 24-h BPs and HRs were similar between products. Mean 24-h HRV low-to-high ratio was also similar for drug 1 (2.04 ± 1.35), drug 2 (1.86 ± 1.35), and brand (2.04 ± 1.77), but was more sustained over time for the brand versus drug 1 (drug × quartile interaction p = 0.017). Differences in Tmax between metoprolol ER products following repeated doses may have implications for drug effects on autonomic balance over the dosing interval.

Personality Predicts the Efficacy of a Physician Leadership Development Program.

It is imperative for health care organizations to foster leadership skills in their workforce. Leadership development programs offer a potential mechanism to achieve this goal. These development programs are likely not equally effective for all participants. This study evaluates the efficacy of one such program and determines personality predictors of its efficacy. Before and after a 12-month leadership development program, 28 physicians from various disciplines completed self-reported measures of leadership knowledge across 3 domains. At baseline, participants also provided personality data across the Big-5 factors of personality as well as 2 narrow facets (learning-goal orientation and preference for collaboration). Results suggest that leadership development programs can increase knowledge across leadership domains. Extraversion and conscientiousness predict changes in knowledge. Learning-goal-orientation and preference for collaboration personality facets provide incremental predictive power. Leadership development programs can improve self-rated knowledge across a range of leadership domains and is differentially effective for people based on their personalities.

Personality Compatibility Within Faculty Mentoring Dyads and Perceived Mentoring Outcomes: Survey Results of Academic Medicine Institutions in the USA.

Mentorship is recognized as a critical approach to support successful careers in academic medicine. Obstacles to successful mentoring relationships include difficulty finding appropriate mentors and poor alignment of mentee/mentor interests and goals. We set out to investigate if concordance or discordance in personality traits of mentees and mentors impacts perceived success of mentoring relationships. Our findings indicated that concordance and discordance on one personality trait, neuroticism, seemed to significantly impact the perceived mentoring relationship success related to career progression. Further work to refine criteria for matching mentees and mentors considering personality traits may impact the effectiveness of mentoring relationships.

Early toxicity and clinical outcomes after chimeric antigen receptor T-cell (CAR-T) therapy for lymphoma.

BACKGROUND: Chimeric antigen receptor T-cell (CAR-T) infusion is associated with early toxicity. Yet, whether early toxicity development holds ramifications for long-term outcomes is unknown. METHODS: From a large cohort of consecutive adult patients treated with CAR-T therapies for relapsed or refractory lymphomas from 2016 to 2019, we assessed progression-free survival (PFS), by toxicity development (cytokine release syndrome (CRS), neurotoxicity, or cardiotoxicity]. We also assessed the relationship of toxicity development to objective disease response, and overall survival (OS). Multivariable regression was utilized to evaluate relationships between standard clinical and laboratory measures and disease outcomes. Differences in outcomes, by toxicity status, were also assessed via 30-day landmark analysis. Furthermore, we assessed the effects of early anti-CRS toxicity therapy use (at ≤grade 2 toxicity) on maximum toxicity grade observed, and long-term disease outcomes (PFS and OS). RESULTS: Overall, from 102 CAR-T-treated patients, 90 were identified as treated with single-agent therapy, of which 88.9% developed toxicity (80 CRS, 41 neurotoxicity, and 17 cardiotoxicity), including 28.9% with high-grade (≥3) events. The most common manifestations were hypotension at 96.6% and fever at 94.8%. Among patients with cardiac events, there was a non-significant trend toward a higher prevalence of concurrent or preceding high-grade (≥3) CRS. 50.0% required tocilizumab or corticosteroids. The median time to toxicity was 3 days; high grade CRS development was associated with cardiac and neurotoxicity. In multivariable regression, accounting for disease severity and traditional predictors of disease response, moderate (maximum grade 2) CRS development was associated with higher complete response at 1 year (HR: 2.34; p=0.07), and longer PFS (HR: 0.41; p=0.02, in landmark analysis), and OS (HR: 0.43; p=0.03). Among those with CRS, relative blood pressure (HR: 2.25; p=0.004), respectively, also associated with improved PFS. There was no difference in disease outcomes, or maximum toxicity grade (CRS, neurotoxicity, or cardiotoxicity) observed, based on the presence or absence of the use of early CRS-directed therapies. CONCLUSIONS: Among adult lymphoma patients, moderate toxicity manifest as grade 2 CRS after CAR-T infusion may associate with favorable clinical outcomes. Further studies are needed to confirm these findings.

Examination of Metoprolol Pharmacokinetics and Pharmacodynamics Across CYP2D6 Genotype-Derived Activity Scores.

Recent CYP2D6 phenotype standardization efforts by CYP2D6 activity score (AS) are based on limited pharmacokinetic (PK) and pharmacodynamic (PD) data. Using data from two independent clinical trials of metoprolol, we compared metoprolol PK and PD across CYP2D6 AS with the goal of determining whether the PK and PD data support the new phenotype classification. S-metoprolol apparent oral clearance (CLo), adjusted for clinical factors, was correlated with CYP2D6 AS (P < 0.001). The natural log of CLo was lower with an AS of 1 (7.6 ± 0.4 mL/minute) vs. 2-2.25 (8.3 ± 0.6 mL/minute; P = 0.012), similar between an AS of 1 and 1.25-1.5 (7.8 ± 0.5 mL/minute; P = 0.702), and lower with an AS of 1.25-1.5 vs. 2-2.25 (P = 0.03). There was also a greater reduction in heart rate with metoprolol among study participants with AS of 1 (-10.8 ± 5.5) vs. 2-2.25 (-7.1 ± 5.6; P < 0.001) and no significant difference between those with an AS of 1 and 1.25-1.5 (-9.2 ± 4.7; P = 0.095). These data highlight linear trends among CYP2D6 AS and metoprolol PK and PD, but inconsistencies with the phenotypes assigned by AS based on the current standards. Overall, this case study with metoprolol suggests that utilizing CYP2D6 AS, instead of collapsing AS into phenotype categories, may be the most precise approach for utilizing CYP2D6 pharmacogenomics in clinical practice.

Effect of beta blocker use and type on hypoglycemia risk among hospitalized insulin requiring patients.

BACKGROUND: Although beta blockers could increase the risk of hypoglycemia, the difference between subtypes on hypoglycemia and mortality have not been studied. This study sought to determine the relationship between type of beta blocker and incidence of hypoglycemia and mortality in hospitalized patients. METHODS: We retrospectively identified non-critically ill hospitalized insulin requiring patients who were undergoing bedside glucose monitoring and received either carvedilol or a selective beta blocker (metoprolol or atenolol). Patients receiving other beta blockers were excluded. Hypoglycemia was defined as any glucose < 3.9 mmol/L within 24 h of admission (Hypo1day) or throughout hospitalization (HypoT) and any glucose < 2.2 mmol/L throughout hospitalization (Hyposevere). RESULTS: There were 1020 patients on carvedilol, 886 on selective beta blockers, and 10,216 on no beta blocker at admission. After controlling for other variables, the odds of Hypo1day, HypoT and Hyposevere were higher for carvedilol and selective beta blocker recipients than non-recipients, but only in basal insulin nonusers. The odds of Hypo1day (odds ratio [OR] 1.99, 95% confidence interval [CI] 1.28, 3.09, p = 0.0002) and HypoT (OR 1.38, 95% CI 1.02, 1.86, p = 0.03) but not Hyposevere (OR 1.90, 95% CI 0.90, 4.02, p = 0.09) were greater for selective beta blocker vs. carvedilol recipients in basal insulin nonusers. Hypo1day, HypoT, and Hyposevere were all associated with increased mortality in adjusted models among non-beta blocker and selective beta blocker recipients, but not among carvedilol recipients. CONCLUSIONS: Beta blocker use is associated with increased odds of hypoglycemia among hospitalized patients not requiring basal insulin, and odds are greater for selective beta blockers than for carvedilol. The odds of hypoglycemia-associated mortality are increased with selective beta blocker use or nonusers but not in carvedilol users, warranting further study.

Organizational Strategies to Create a Burnout-resistant Environment.

Burnout afflicts a significant number of academic faculty and clinicians. There are many efforts the individual can undertake to prevent or lessen burnout. However, it not likely these will be successful without the institutional environment that promotes and atmosphere that assures self-efficacy, a sense of value and meaning and clear communication between leaders and members of the organization. This review discusses the factors that organizations and their leaders can leverage to create such an environment. Such measures are critically important not only for the health of the individual but to the organization as well.

Association of Genetic Polymorphisms in the Beta-1 Adrenergic Receptor with Recovery of Left Ventricular Ejection Fraction in Patients with Heart Failure.

Two common genetic polymorphisms in the beta-1 adrenergic receptor (ADRB1 Ser49Gly [rs1801252] and Arg389Gly [rs1801253]) significantly affect receptor function in vitro. The objective of this study was to determine whether ADRB1 Ser49Gly and Arg389Gly are associated with recovery of left ventricular ejection fraction (LVEF) in patients with heart failure. Patients with heart failure and baseline LVEF ≤ 40% were genotyped (n = 98), and retrospective chart review assessed the primary outcome of LVEF recovery to ≥ 40%. Un/adjusted logistic regression models revealed that Ser49Gly, but not Arg389Gly, was significantly associated with LVEF recovery in a dominant genetic model. The adjusted odds ratio for Ser49 was 8.2 (95% CI = 2.1-32.9; p = 0.003), and it was the strongest predictor of LVEF recovery among multiple clinical variables. In conclusion, patients with heart failure and reduced ejection fraction that are homozygous for ADRB1 Ser49 were significantly more likely to experience LVEF recovery than Gly49 carriers.

Etiology-dependent impairment of relaxation kinetics in right ventricular end-stage failing human myocardium.

BACKGROUND: In patients with end-stage heart failure, the primary etiology often originates in the left ventricle, and eventually the contractile function of the right ventricle (RV) also becomes compromised. RV tissue-level deficits in contractile force and/or kinetics need quantification to understand involvement in ischemic and non-ischemic failing human myocardium. METHODS AND RESULTS: The human population suffering from heart failure is diverse, requiring many subjects to be studied in order to perform an adequately powered statistical analysis. From 2009-present we assessed live tissue-level contractile force and kinetics in isolated myocardial RV trabeculae from 44 non-failing and 41 failing human hearts. At 1 Hz stimulation rate (in vivo resting state) the developed active force was not different in non-failing compared to failing ischemic nor non-ischemic failing trabeculae. In sharp contrast, the kinetics of relaxation were significantly impacted by disease, with 50% relaxation time being significantly shorter in non-failing vs. non-ischemic failing, while the latter was still significantly shorter than ischemic failing. Gender did not significantly impact kinetics. Length-dependent activation was not impacted. Although baseline force was not impacted, contractile reserve was critically blunted. The force-frequency relation was positive in non-failing myocardium, but negative in both ischemic and non-ischemic myocardium, while the ß-adrenergic response to isoproterenol was depressed in both pathologies. CONCLUSIONS: Force development at resting heart rate is not impacted by cardiac pathology, but kinetics are impaired and the magnitude of the impairment depends on the underlying etiology. Focusing on restoration of myocardial kinetics will likely have greater therapeutic potential than targeting force of contraction.

Anaerobic muscle strengthening physical activity and depression severity among USA adults.

We investigated the association between depression and anaerobic physical activity (while controlling aerobic physical activity), using a nationally representative sample of USA adults (n = 7354) who participated in the cross sectional National Health and Nutrition Examination Survey (NHANES, 1999-2006). We defined depression using the validated "Patient Health Questionnaire" (PHQ9) scale of 0-27 as PHQ9 ≥ 10. Severity of depression was classified by clinically established PHQ9 levels: mild (5-9), dysthymic (10-14), moderate (15-19), and major depression (≥20). We used logistic regression to estimate adjusted odds ratios of depression associated with distinct types of activity (only aerobic, only anaerobic, combined regime). We used multinomial logistic regression to examine associations of anaerobic activity with various severity levels of depression (mild, dysthymic, moderate, and major depression) with adjustment for aerobic activity. Women had higher prevalence of depression than men (8.4% versus 5.7%), whereas anaerobic muscle strengthening activity was more common in men than women (35% versus 24%). Adjusting for aerobic activity, anaerobic activity was inversely associated with depression (PHQ9 ≥ 10) in women under 50 (OR = 0.57; 95%CI = 0.41-0.81), all women (OR = 0.59; 0.43-0.80), men under 50 (OR = 0.85; 0.58-1.2), and all men (OR = 0.72; 0.51-1.01). Anaerobic activity was inversely associated with severity level of depressive symptoms in women and men. The combined regimen of anaerobic muscle strengthening activity and meeting the Physical Activity Guideline for America (PAGA) was related to the lowest odds ratio of depression in women (OR = 0.50; 95%CI = 0.33-0.75) and men (OR = 0.39; 95%CI = 0.23-0.62). Independent of aerobic physical activity, anaerobic muscle strengthening activity is significantly and inversely associated with depression among USA adults.

Pilot Randomized Controlled Trial to Reduce Readmission for Heart Failure Using Novel Tablet and Nurse Practitioner Education.

BACKGROUND: Heart failure education programs are not standardized. The best form of education is unclear. We evaluated whether addition of a novel tablet application to nurse practitioner (NP) education was superior to NP education alone in reducing 30-day readmission after heart failure hospitalization. METHODS: From February 2015-March 2016, patients admitted to a quaternary academic center with primary diagnosis of heart failure were randomized to 1) treatment - NP education plus tablet application (interactive conditional logic program that flags patient questions to medical staff), or 2) control - NP education. The primary outcome was reduction in 30-day readmission rate. Secondary outcomes included satisfaction and education assessed via survey. RESULTS: Randomization included 60 patients to treatment and 66 to control. A total of 13 patients withdrew prior to intervention (treatment n = 4, control n = 1) or were lost to follow-up (treatment n = 3, control n = 5). The 30-day readmission rate trended lower for treatment compared with control, but results were not statistically significant (13.2% [7/53], 26.7% [16/60], respectively, P = .08). Similarly, satisfaction trended higher with treatment than control (P = .08). Treatment patients rated explanations from their physicians higher than control (Always: 83.7%, 55.8%, respectively, P = .01). CONCLUSIONS: NP education plus tablet use was not associated with significantly lower 30-day readmission rates in comparison with NP alone, but a positive trend was seen. Patient satisfaction trended higher and heart failure explanations were better with NP education plus tablet. A larger study is needed to determine if NP education plus tablet reduces readmission rates following heart failure admission.

The CARE Inventory: A Self-Reflective, Behavior-Based Instrument to Guide Professional Development and Mentorship of Academic Faculty.

Introduction: Traditional needs assessments often rely on self-reported skill levels. To gather more objective and growth-focused data, we developed a behavior-based inventory to measure perceived faculty competence and desired areas for growth in four common domains of academic medicine: clinical, administrative/leadership, research, and education (CARE). Methods: Competencies in teaching, research, and professional development and leadership noted in the literature were used as the foundation of our instrument. Clinical service topics were added, and questions were vetted with the executive committee of our faculty development center. A behavior-based inventory was developed to enhance self-reporting of competency. The instrument was piloted with faculty at an external institution and revisions made prior to data collection. Results: In May 2016, the CARE Inventory was sent to all full-time faculty members in the Ohio State University College of Medicine (n = ∼1,800). We received 350 responses (20% response rate). Individual reports were generated and sent to the faculty member and his/her identified mentor for individual professional development. Summary data were used in aggregate for professional development program planning. Discussion: Anchoring measurement to current and desired future behavior allows for more self-reflective and growth-oriented assessment for individuals, and results can inform tactical faculty development by both individual and program. We believe this is a scalable and generalizable instrument other academic medical and health sciences programs could use both as a needs assessment tool for program planning and for individualized development plans with faculty and their mentors.

Patient Perceptions on Facilitating Follow-Up After Heart Failure Hospitalization.

BACKGROUND: Timely follow-up after hospitalization for heart failure (HF) is recommended. However, follow-up is suboptimal, especially in lower socioeconomic groups. Patient-centered solutions for facilitating follow-up post-HF hospitalization have not been extensively evaluated. METHODS AND RESULTS: Face-to-face surveys were conducted between 2015 and 2016 among 83 racially diverse adult patients (61% African American, 34% Caucasian, and 5% Other) hospitalized for HF at a university hospital centered in a low-income area of Columbus, Ohio. Patient perceptions of methods to facilitate follow-up post-HF hospitalization and likelihood of using interventions were investigated using a Likert scale: 1=very much to 5=not at all. Results were analyzed by Wilcoxon signed-rank test with Bonferroni correction. The response rate was 82%. The annual household income was <$35 000 for 49% of patients. An appointment near the patient's home was the most desired intervention (77%), followed by reminder message (73%), transportation to appointment (63%), and elimination of copayment (59%). Interventions most likely to be used if provided were similarly ranked: reminder message (48%), appointment near home (46%), elimination of copay (46%), and transportation to appointment (39%). There were significant differences (P=0.001) in high-ranking interventions related to location (appointment near home, transportation, home appointment) and reminder for visit compared with low-ranking interventions related to time (weekend appointment, appointment after 5 pm) and telemedicine. CONCLUSIONS: Among this cohort of racially diverse low-income patients hospitalized with HF, an appointment near the patient's home and a reminder message were the most desired interventions to facilitate follow-up. Further study of similar populations nationwide is warranted.

CYP2D6 Genetic Variation and Beta-Blocker Maintenance Dose in Patients with Heart Failure.

PURPOSE: This study examined whether a CYP2D6 polymorphism (CYP2D6*4) was related to beta-blocker maintenance dose in patients with heart failure. METHODS: Logistic regression modeling was utilized in a retrospective chart-review analysis of heart-failure patients (60% Male, 90% of European descent) to assess whether CYP2D6*4 (non-functional CYP2D6 allele present in 1 of 5 individuals of European descent) is associated with maintenance dose of carvedilol (n = 65) or metoprolol (n = 33). RESULTS: CYP2D6*4 was associated with lower maintenance dose of metoprolol (OR 0.13 [95% CI 0.02-0.75] p = 0.023), and a trend was observed between CYP2D6*4 and higher maintenance dose of carvedilol (OR 2.94 [95% CI 0.84-10.30] p = 0.093). None of the patients that carried CYP2D6*4 achieved the recommended target dose of metoprolol (200 mg/day). CONCLUSION: Consistent with the role of CYP2D6 in the metabolism of metoprolol, the tolerated maintenance dose of metoprolol was lower in CYP2D6*4 carriers compared to non-carriers. Consistent with the role of CYP2D6 in activation of carvedilol, tolerated maintenance dose of carvedilol was higher in CYP2D6*4 carriers compared to non-carriers. Further investigation is warranted to ascertain the potential of CYP2D6 as a potential predictive biomarker of beta-blocker maintenance dose in heart failure patients.
