18F-FDG/13N-ammonia cardiac PET findings in ATTR cardiac amyloidosis.

18F-flurodeoxyglycose (FDG)/13N-ammonia positron emission tomography/computed tomography (PET/CT) is frequently utilized to evaluate cardiac sarcoidosis (CS) but findings can reflect other forms of myocardial inflammation or altered myocardial metabolic activity. Herein, we present five cases where cardiac PET findings suggested CS, but right ventricular endomyocardial biopsy samples revealed ATTR-type cardiac amyloidosis.

Multidimensional Evaluation of Screening Brief Intervention and Referral to Treatment Training for Medical Students.

OBJECTIVE: Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based approach to identifying and addressing alcohol use in non-specialty settings. Many medical schools teach SBIRT, but most published evaluations of these efforts exclude rigorous skill assessments and teaching methods. METHODS: During the 2017-2018 academic year, 146 third-year medical students received classroom-based learning on SBIRT and motivational interviewing (MI) and at least two SBIRT practices with feedback as part of a 4-week psychiatry clerkship. The objective of this curriculum was to improve SBIRT knowledge, attitudes, and confidence and enable learners to skillfully deliver SBIRT. Outcomes evaluated included satisfaction, knowledge, attitudes and confidence, and clinical skill in delivering SBIRT to a standardized patient (rated by the actor, as well as an expert). RESULTS: Results indicated acceptable satisfaction at post-curriculum and significant improvements in attitudes and knowledge from pre- to post-curriculum. On the clinical skills exam, all students were rated as having mastered at least 80% of SBIRT elements by standardized patients and 91.8% were rated at this level by a faculty expert. Student attitudes and knowledge were unrelated to expert ratings, and standardized patient ratings had limited associations with expert ratings. CONCLUSIONS: These results suggest curriculum objectives were achieved and provide unique contributions to the SBIRT curricular outcome research for healthcare trainees. Other findings included that trainee knowledge and confidence may not relate to skill, and standardized patient feedback provides different information on SBIRT and MI skill than expert ratings.

Disability as Diversity: Educational Opportunities for Family Medicine.

Disability is an aspect of diversity that often receives less attention in healthcare and medical education than other aspects of diversity, such as gender or race. Approximately one in four Americans has some type of disability, and individuals with disabilities have less access to healthcare, greater dissatisfaction with their healthcare, and report being in poorer health than individuals without a disability. Although many factors likely contribute to these disparities, physician perception and understanding of disability have been examined as potential pathways that influence health inequity. It is important to incorporate disability as a form of diversity in family medicine education to train physicians that provide excellent care to patients with disabilities and work toward equitable healthcare for them. In this article, we review definitions and data related to disability. We examine disparities and forms of stigmatization toward individuals with disabilities. We then present scenarios in the context of family medicine residency education that involve stigmatization of a person with a disability. Following each scenario, we identify the stigmatizing problem and its potential impact on the individual with a disability. In addition, we outline a potential intervention as an individual witnessing this scenario, and an alternative, non-stigmatizing approach to the scenario. Finally, we present proposed core competencies on disability for health care education and potential strategies to incorporate these competencies into family medicine curricula.

Chronically Hypoxic Fetal Lambs Supported by an Extra-Uterine Device Exhibit Mitochondrial Dysfunction and Elevations of Hypoxia Inducible Factor 1-Alpha.

INTRODUCTION: We have recently developed an extra-uterine environment for neonatal development (EXTEND) capable of supporting premature fetal lambs and have been able to replicate hypoxic in utero conditions by controlling fetal oxygen delivery. In this study, we investigated the fetal mitochondrial response to hypoxia. METHODS: Eight premature fetal lambs were delivered via hysterotomy and transitioned to extra-uterine support for 3 weeks. The lambs were divided into 2 groups: normoxic fetuses which maintained physiologic oxygen delivery and hypoxic fetuses in which oxygen delivery was significantly reduced. Control fetuses were delivered via hysterotomy but not cannulated. Measurements of mitochondrial membrane potential (MMP) were performed in peripheral blood mononuclear cells. RESULTS: There were no significant differences in MMP between normoxic EXTEND fetuses and controls. Hypoxic fetuses had significantly more depolarized mitochondria compared to normoxic fetuses overall, and these changes were specifically appreciated in weeks 1 and 2, but not by week 3. Hypoxic fetuses had significantly elevated levels of HIF-1α compared to normoxic fetuses in the first 2 weeks. DISCUSSION: Normoxic fetal lambs supported by EXTEND demonstrate normal mitochondrial function as evidenced by equivalent membrane potentials compared to control fetuses. Hypoxic fetuses exhibit mitochondrial dysfunction, though they do show evidence of adaptation after 3 weeks of hypoxic exposure.

Erythropoietin Prevents Anemia and Transfusions in Extremely Premature Lambs Supported by an EXTrauterine Environment for Neonatal Development (EXTEND).

BACKGROUND: We recently developed an EXTrauterine Environment for Neonatal Development (EXTEND) that provides physiologic support for premature lambs. Here, we assess the efficacy of exogenous erythropoietin (EPO) to prevent anemia and transfusions on EXTEND. MATERIALS AND METHODS: Lambs were cannulated at 0.7 gestation and supported on EXTEND for up to 4 weeks. The lambs were divided into three groups: (1) No EPO, (2) Low EPO (300 U kg-1 per day), and (3) High EPO (800 U kg-1 per day). Daily hematocrit and weekly complete blood count were assessed. RESULTS: The mean percentage change in hematocrit from baseline was significantly different between the groups (No EPO -23.6 ± 7.8% vs. Low EPO -16.6 ± 6.4% vs. High EPO +2.6 ± 6.6%; p = 0.02). This occurred despite a greater median number of blood transfusions in the No EPO group (5 vs. 1 vs. 0; p = 0.02). EPO administration was associated with a higher mean corpuscular volume (MCV; p < 0.01) and reticulocyte count (p = 0.02). The High EPO group was comparable to in utero control fetuses with respect to hematocrit (p = 0.49), MCV (p = 0.24), and reticulocyte count (p = 0.68). CONCLUSIONS: EPO (800 U kg-1 per day) prevents anemia, eliminates transfusions, and restores normal red blood cell indices in premature lambs supported by EXTEND.

Umbilical cannulation optimizes circuit flows in premature lambs supported by the EXTra-uterine Environment for Neonatal Development (EXTEND).

KEY POINTS: Bronchopulmonary dysplasia is a disease of extreme prematurity that occurs when the immature lung is exposed to gas ventilation. We designed a novel 'artificial womb' system for supporting extreme premature lambs (called EXTEND) that obviates gas ventilation by providing oxygen via a pumpless arteriovenous circuit with the lamb submerged in sterile artificial amniotic fluid. In the present study, we compare different arteriovenous cannulation strategies on EXTEND, including carotid artery/jugular vein (CA/JV), carotid artery/umbilical vein (CA/UV) and umbilical artery/umbilical vein (UA/UV). Compared to CA/JV and CA/UV cannulation, UA/UV cannulation provided significantly higher, physiological blood flows to the oxygenator, minimized flow interruptions and supported significantly longer circuit runs (up to 4 weeks). Physiological circuit blood flow in UA/UV lambs made possible normal levels of oxygen delivery, which is a critical step toward the clinical application of artificial womb technology. ABSTRACT: EXTEND (EXTra-uterine Environment for Neonatal Development) is a novel system that promotes physiological development by maintaining the premature lamb in a sterile fluid environment and providing gas exchange via a pumpless arteriovenous oxygenator circuit. During the development of EXTEND, different cannulation strategies evolved with the aim of improving circuit flow. The present study examines how different cannulation strategies affect EXTEND circuit haemodynamics in extreme premature lambs. Seventeen premature lambs were cannulated at gestational ages 105-117 days (term 145-150 days) and supported on EXTEND for up to 4 weeks. Experimental groups were distinguished by cannulation strategy: carotid artery outflow and jugular vein inflow (CA/JV; n = 4), carotid artery outflow and umbilical vein inflow (CA/UV; n = 5) and double umbilical artery outflow and umbilical vein inflow (UA/UV; n = 8). Circuit flows and pressures were measured continuously. As we transitioned from CA/JV to CA/UV to UA/UV cannulation, mean duration of circuit run and weight-adjusted circuit flows increased (P < 0.001) and the frequency of flow interruptions declined (P < 0.05). Umbilical vessels generally accommodated larger-bore cannulas, and cannula calibre was directly correlated with circuit pressures and indirectly correlated with flow:pressure ratio (a measure of post-membrane resistance). We conclude that UA/UV cannulation in fetal lambs on EXTEND optimizes circuit flow dynamics and flow stability and also supports circuit flows that closely approximate normal placental flow.

End-of-Life Discussions in Patients With Heart Failure.

BACKGROUND: Although guidelines call on clinicians to conduct regular conversations about advance care planning and end-of-life (EOL) preferences with patients with heart failure (HF), research suggests that physicians often avoid these discussions. METHODS AND RESULTS: From January 20, 2014, to January 18, 2016, Southeastern Minnesota residents hospitalized with acute decompensated HF (ADHF) at Mayo Clinic hospitals were enrolled into an observational cohort study that included the administration of face-to-face questionnaires. Risk of death (prognosis) was estimated using the Meta-analysis Global Group in Chronic Heart Failure score. Among 400 patients (mean age 77.7 years, 46% female, 48% preserved ejection fraction), only 69 (17%) reported previously discussing EOL wishes with their physician. Patients reporting EOL discussions more often had an advance directive (81% vs 66%; P = .009), recognized the term "hospice" (96% vs 87%; P = .027), and had more favorable attitudes of dying and hospice (P = .030). Resuscitation preferences and rates of completion of advance directives varied with prognosis, although patient-clinician EOL discussions did not. CONCLUSIONS: The majority of patients hospitalized with ADHF did not recall discussing their preferences for EOL care with their physician. This represents an important modifiable gap in the optimal longitudinal care of HF patients.

Dalba Got Back? Use of Dalbavancin for the Treatment of Vertebral Osteomyelitis.

Data evaluating dalbavancin use for vertebral osteomyelitis remain limited. In our retrospective cohort, 29 of 34 (85.3%) patients completed their dalbavancin course. Adverse reactions occurred for 6 (17.6%) and infection recurrence in 3 (8.8%) within 90 days. Dalbavancin appears to be safe and well-tolerated for vertebral osteomyelitis.

Artificial intelligence-based screening for cardiomyopathy in an obstetric population: A pilot study.

Background: Cardiomyopathy is a leading cause of pregnancy-related mortality and the number one cause of death in the late postpartum period. Delay in diagnosis is associated with severe adverse outcomes. Objective: To evaluate the performance of an artificial intelligence-enhanced electrocardiogram (AI-ECG) and AI-enabled digital stethoscope to detect left ventricular systolic dysfunction in an obstetric population. Methods: We conducted a single-arm prospective study of pregnant and postpartum women enrolled at 3 sites between October 28, 2021, and October 27, 2022. Study participants completed a standard 12-lead ECG, digital stethoscope ECG and phonocardiogram recordings, and a transthoracic echocardiogram within 24 hours. Diagnostic performance was evaluated using the area under the curve (AUC). Results: One hundred women were included in the final analysis. The median age was 31 years (Q1: 27, Q3: 34). Thirty-eight percent identified as non-Hispanic White, 32% as non-Hispanic Black, and 21% as Hispanic. Five percent and 6% had left ventricular ejection fraction (LVEF) <45% and <50%, respectively. The AI-ECG model had near-perfect classification performance (AUC: 1.0, 100% sensitivity; 99%-100% specificity) for detection of cardiomyopathy at both LVEF categories. The AI-enabled digital stethoscope had an AUC of 0.98 (95% CI: 0.95, 1.00) and 0.97 (95% CI: 0.93, 1.00), for detection of LVEF <45% and <50%, respectively, with 100% sensitivity and 90% specificity. Conclusion: We demonstrate an AI-ECG and AI-enabled digital stethoscope were effective for detecting cardiac dysfunction in an obstetric population. Larger studies, including an evaluation of the impact of screening on clinical outcomes, are essential next steps.

Arrhythmic manifestations and outcomes of definite and probable cardiac sarcoidosis.

BACKGROUND: The 2014 Heart Rhythm Society consensus statement defines histological (definite) and clinical (probable) diagnostic categories of cardiac sarcoidosis (CS), but few studies have compared their arrhythmic phenotypes and outcomes. OBJECTIVE: The purpose of this study was to evaluate the electrophysiological/arrhythmic phenotype and outcomes of patients with definite and probable CS. METHODS: We analyzed the arrhythmic/electrophysiological phenotype in a single-center North American cohort of 388 patients (median age 56 years; 39% female, n = 151) diagnosed with definite (n = 58) or probable (n = 330) CS (2000-2022). The primary composite outcome was survival to first ventricular tachycardia/fibrillation (VT/VF) event or sudden cardiac death. Key secondary outcomes were also assessed. RESULTS: At index evaluation, in situ cardiac implantable electronic devices and antiarrhythmic drug use were more common in definite CS. At a median follow-up of 3.1 years, the primary outcome occurred in 22 patients with definite CS (38%) and 127 patients with probable CS (38%) (log-rank, P = .55). In multivariable analysis, only a higher ratio of the 18F-fluorodeoxyglucose maximum standardized uptake value of the myocardium to the maximum standardized uptake value of the blood pool (hazard ratio 1.09; 95% confidence interval 1.03-1.15; P = .003, per 1 unit increase) was associated with the primary outcome. During follow-up, patients with definite CS had a higher burden of device-treated VT/VF events (mean 2.86 events per patient-year vs 1.56 events per patient-year) and a higher rate of progression to heart transplant/left ventricular assist device implantation but no difference in all-cause mortality compared with patients with probable CS. CONCLUSION: Patients with definite and probable CS had similarly high risks of first sustained VT/VF/sudden cardiac death and all-cause mortality, though patients with definite CS had a higher overall arrhythmia burden. Both CS diagnostic groups as defined by the 2014 Heart Rhythm Society criteria require an aggressive approach to prevent arrhythmic complications.

Neuropsychological assessment of decision making in alcohol-dependent commercial pilots.

BACKGROUND: The aim of this exploratory archival study was to discern the utility of the Iowa Gambling Task (IGT) in identifying adaptive decision-making capacities among pilots with a history of alcohol dependence both with and without Cluster B personality features. METHODS: Participants included 18 male airmen at the rank of captain with a history of receiving alcohol dependence treatment and subsequent referral for a fitness-for-duty evaluation. Data from prior comprehensive neuropsychological evaluations conducted in a private practice setting at the mandate of the FAA utilizing criteria outlined in the HIMS program was used. ANOVA was conducted to compare pilots with (N = 4) and without Cluster B personality features (N = 14) on measures of decisionmaking capacities, intelligence, and executive functioning. RESULTS: Pilots with Cluster B personality features were found to have a significantly lower Total Net T-Score on IGT (M = 35.00, SD = 9.27) than pilots without features of Cluster B (M = 56.36, SD = 9.55). Furthermore, with the exception of the first 20 cards (i.e., Net 1); the groups significantly differed in their Net scores. No statistically significant difference was found on airmen's intelligence and executive functioning. DISCUSSION: The present study found that alcohol-dependent airmen with Cluster B personality features evidenced significantly poorer decisionmaking capacities as measured by the ICT in comparison to alcohol dependent airman without Cluster B personality features. Implications and limitations of the study are discussed.

Mental Health Stigma in Active Duty Service Members Receiving Mental Health Services.

INTRODUCTION: Mental health treatment is a service for military service members who have experienced psychological injury or trauma. Unfortunately, the stigma associated with treatment can prevent many service members from seeking and receiving treatment designed to help them recover. Previous studies have examined the impacts of stigma among military personnel as well as civilians; however, stigma among service members currently receiving mental health treatment is unknown. The purpose of this study is to understand the relationships between stigma, demographic variables, and mental health symptoms in a sample of active duty service members receiving mental health services in a partial hospitalization program. MATERIALS AND METHODS: This cross-sectional, correlational study collected data from participants in the Psychiatric Continuity Services clinic at Walter Reed National Military Medical Center, which offers a four-week partial hospitalization program specializing in trauma recovery for active duty service members of all branches. The data from behavioral health assessments were gathered over a 6-month timespan, including the Behavior and Symptom Identification Scale-24, Patient Health Questionnaire-9, Generalized Anxiety Disorder 7-item scale, and Post-traumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). Stigma was measured using the Military Stigma Scale (MSS). The demographic data collected included military rank and ethnicity. Pearson correlations, t-tests, and linear regression were used to further explore the relationships between the MSS scores, demographic covariates, and behavioral health measures. RESULTS: In unadjusted linear regression models, non-white ethnicity and higher behavioral health assessment intake measures were associated with higher MSS scores. However, after adjusting for gender, military rank, race, and all mental health questionnaires, only Post-traumatic Stress Disorder Checklist for DSM-5 intake scores remained associated with MSS scores. No relationship between gender or military rank and average stigma score was observed in either the unadjusted or adjusted regression models. One-way analysis of variance detected a statistically significant difference between the white/Caucasian group and Asian/Pacific Islander group and a near significant difference between white/Caucasian group and black/African American group. The rates of stigma were higher in non-whites than whites. CONCLUSIONS: In this active duty military cohort, greater mental health stigma was associated with greater severity of mental health symptoms, especially post-traumatic stress symptoms. Some evidence found that ethnicity may also play a role in stigma score differences, particularly in the Asian/Pacific Islander group. Service providers could consider assessing mental health stigma to meet the clinical needs of their patients within the context of their willingness to obtain and adhere to treatment. Anti-stigma efforts to reduce stigma and its impacts on mental health are discussed. Additional research investigating the effect stigma has on treatment outcomes would help guide the relative importance of assessing stigma, in addition to other behavioral health realms.

Clinical Response to Tumor Necrosis Factor-α Inhibitor Therapy in the Management of Cardiac Sarcoidosis.

Evidence that tumor necrosis factor-α (TNF-α) inhibitors may benefit patients with cardiac sarcoidosis (CS) is limited to small case series and both imaging and clinical outcomes in this population are not well known. This study aimed to evaluate the disease course of patients with CS treated with either infliximab or adalimumab therapy based on serial 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging and clinical outcomes. An institutional CS research database was queried for patients treated with TNF-α inhibitors between 2016 and 2021. Outcomes included (1) change in mean prednisone dose, (2) FDG-PET improvement, and (3) unplanned hospitalizations, advanced heart failure therapies, or death. Our query yielded 31 patients with CS. A total of 13 patients were on infliximab, 15 patients were on adalimumab, and 3 patients were on adalimumab before transitioning to infliximab. Mean prednisone dose decreased between FDG-PET immediately preceding TNF-α and second after TNF-α FDG-PET (18.6 ± 15.7 mg to 7.7 ± 12.4 mg, p = 0.018). A significant decrease was seen in the mean number of segments demonstrating FDG uptake between most recent pre-TNF-α and first after TNF-α inhibitor FDG-PET (mean segments = 4.2 vs 3.1, p = 0.048). Between earliest pre-TNF-α and first after TNF-α FDG-PET there was a numerical decrease in average myocardial maximum standard uptake values (SUVmax) (4.4 vs 3.1, p = 0.18), and the ratio of SUVmax myocardium:SUVmax blood pool (1.9 vs 1.5, p = 0.26). Within 36 months of initiating TNF-α inhibitor, 4 patients (13%) experienced unplanned cardiovascular hospitalization (median time to hospitalization = 12.1 months). In conclusion, in patients with CS, TNF-α inhibitor therapy is associated with decreased glucocorticoid use, numerical decrease in cardiac FDG uptake, and minimal cardiac morbidity.

The hidden cost of dalbavancin: OPAT RN time required in coordination for persons who use drugs.

Background: Serious infections in persons who use drugs (PWUD) are rising. Dalbavancin, due to its extended half-life, offers an alternative treatment for patients in whom standard of care antibiotics are not feasible or practical, allowing for reduced hospital days and the avoidance of central line placement or the use of complex oral regimens. Objectives: We aim to describe the time and effort required for coordination of dalbavancin courses by outpatient registered nurses (RNs) and other outpatient parenteral antimicrobial therapy (OPAT) staff. Design and methods: We conducted a retrospective review of adult patients with documented substance use who received at least one dose of dalbavancin and quantified the number of interventions required by our OPAT RNs and other OPAT staff for coordination of dalbavancin courses. Additionally, detailed data on time spent per intervention were prospectively collected for a 1-month period. Results: A total of 52 patients with 53 dalbavancin courses were included. Most substance use was intravenous. Infectious diagnoses included bone and joint infections (61%) and endocarditis (7%), in addition to skin and soft tissue infections (19%). Infections were most commonly caused by Staphylococcus aureus (62%). RN intervention was required in the coordination of 60% of all courses and in 77% of courses in which at least one outpatient dose was needed. Adverse reactions occurred in one patient (2%) and 90-day readmissions due to infectious complications occurred in two patients (4%). Detailed time analysis was performed for seven consecutive patients, with a total of 179 min spent by OPAT RNs on coordination. Conclusions: The ease of dalbavancin administration does not eliminate the need for extensive RN coordination for successful administration of doses in the outpatient setting for PWUD. This need should be accounted for in program staffing to help increase successful dalbavancin course completion.

Analysis of Cardiac Computed Tomography Anatomy in Patients With Severe Tricuspid Regurgitation Considered for Transcatheter Intervention.

Background: Severe tricuspid regurgitation (TR) is associated with considerable morbidity/mortality in an elderly population with multiple comorbidities. There is interest in transcatheter interventions to manage severe TR. Understanding complex right heart (RH) geometry and tricuspid valve shape and size has implications for patient/device selection for transcatheter intervention. We characterized RH anatomy by computed tomography in patients with symptomatic severe TR considered for intervention. Methods: The retrospective Mayo Clinic study included 29 patients with an echocardiogram and cardiac computed tomography angiogram considered for intervention of severe TR from March 01, 2016 to December 15, 2020. Patients were divided into 2 groups: intervention (surgical or transcatheter; n = 17) and medical management alone (n = 12). Results: Mean age was 83 ± 8 (83% female), 100% had atrial fibrillation, and 62% had chronic kidney disease ≥3a. Ninety-seven percent were symptomatic, 93% had been prescribed loop diuretics, and 24% had device leads. Mean tricuspid annular plane systolic excursion was 16.8 ± 4.5 mm, effective regurgitant orifice area was 81 ± 33 mm2, and cardiac index was 2.6 ± 0.6 L/min/m2. Forty-one percent had at least moderate right ventricular (RV) dysfunction with a mean RV systolic pressure of 46 ± 16 mmHg. Patients receiving intervention had significantly larger effective regurgitant orifice area (101 ± 33 vs. 63 ± 22 mm2, p = 0.033), shorter tricuspid leaflet tenting length (6.5 ± 3.0 vs. 8.9 ± 2.7 mm, p = 0.042), and smaller annuloplasty diagnostic perimeter during diastole (120.1 ± 16.6 vs. 131.1 ± 7.4 mm, p = 0.041). Intervention patients tended to have better right ventricular function, smaller RV and inferior vena cava size, and more severe symptoms. The maximal tricuspid annulus diameter in systole and diastole was 51 ± 5 and 53 ± 7 mm, respectively. Conclusions: Severe TR patients referred for transcatheter intervention present with severe RH enlargement with a large proportion having tricuspid annulus dimensions outside the range for current devices available in clinical trials. The presented data have implications for device development/selection and procedural feasibility.

The Mechanism and Natural History of Mitral Regurgitation in Cardiac Sarcoidosis.

Cardiac sarcoidosis (CS) is an infl/ammatory cardiomyopathy that can present with mitral regurgitation (MR), but few studies describe the mechanisms and natural history of MR in CS. We queried an institutional registry of 512 patients with CS for moderate or greater MR at diagnosis. Baseline demographic and echocardiography (TTE) data were collected. MR was classified by Carpentier type. Positron emission tomography was analyzed for 2-deoxy-2-[fluorine-18] fluoro-d-glucose (FDG) avidity of anterolateral and posteromedial papillary muscles. Follow-up TTE and positron emission tomography imaging of patients treated with immunosuppression was analyzed for MR severity and FDG avidity changes. Fifty-four patients were identified. Mean left ventricular ejection fraction was 39.3%, effective regurgitant orifice 0.34 cm2, and MR regurgitant volume 46.3 ml. Carpentier type I was the most common MR mechanism (46.3%). Forty-one patients had follow-up TTE (median follow-up 1.7 years, interquartile range 2.6 years). Evaluating preprocedural follow-up TTE only, MR severity was significantly reduced, with 37% of patients showing reduction by at least 1 severity grade (p = 0.04). With postprocedural TTE included, 61% of patients showed alleviation of MR severity with mean decrease in grade - 0.98 (p <0.001). Sixty-eight percent of patients had anterolateral/posteromedial FDG avidity. Papillary muscle FDG avidity resolved in 80% of patients (n = 20, median follow-up 1.6 years, interquartile range 2.5 years). In conclusion, Carpentier type I functional MR is the most common MR mechanism in CS. MR severity and papillary muscle FDG avidity decrease after treatment, and MR resolution is further strengthened by procedural intervention in a minority of patients, suggesting an overall favorable natural history of MR in CS.

Assessing self-efficacy to reduce one's drinking: further evaluation of the Alcohol Reduction Strategies-Current Confidence questionnaire.

AIMS: To evaluate the psychometric properties of a previously published questionnaire designed to assess young drinkers' self-efficacy to employ 31 cognitive-behavioral alcohol reduction strategies. METHODS: Undergraduates (n = 353) recruited from a large Midwestern university completed the previously published Alcohol Reduction Strategies-Current Confidence questionnaire (and other measures) for a self-selected heavy drinking setting. RESULTS: Item loadings from a principal components analysis, a high internal consistency reliability coefficient, and a moderate mean inter-item correlation suggested that all 31 items comprised a single scale. Correlations of questionnaire scores with selected aspects of drinking history and personality provided support for criterion and discriminant validity, respectively. Women reported higher current confidence to use these strategies than did men, but current confidence did not vary as a function of recent binge status. CONCLUSION: Given this further demonstration of its psychometric qualities, this questionnaire holds promise as a clinical tool to identify clients who lack confidence in their ability to employ cognitive-behavioral coping strategies to reduce their drinking.
