Question: Hypertrophic cardiomyopathy (HCM) is associated with myocardial scarring and ventricular tachycardia (VT). Contrast-enhanced cardiac magnetic resonance imaging (CE-CMR) can quantify myocardial scar, and scar imaging has been documented in patients with HCM. We investigated the assessment of myocardial scar in HCM patients using CE-CMR, and its correlation with proven VT.', 'Twenty-five patients (mean age 54 +/- 8) with HCM who underwent CE-CMR were identified, and clinical data obtained from chart review. Parameters of LV function were calculated from cine imaging, and myocardial scar was assessed using delayed enhancement imaging following gadolinium administration.', 'Myocardial scar was detected in 16 (64%) patients with a mean mass 9 +/- 15 g. Scar was patchy, mid-myocardial and located in the basal anteroseptum, and RV insertion sites. Scar was seen in septal, apical and concentric variants of HCM. Scar mass correlated with both LV Mass (r2 = 0.74) and maximal LV wall thickness (r2 = 0.42). VT occurred in 32% of patients, and was associated with both increased scar mass and wall thickness compared to non-VT patients (21 +/- 22 g vs. 4 +/- 6 g, and 2.4 +/- 0.5 cm vs. 1.8 +/- 0.5 cm, p < 0.05). LV size and function were similar in patients with and without VT. A scar mass of >7 g predicted the presence of VT with a sensitivity of 75% and specificity 82%.

Question: Obesity has shown a positive association with depression. We aimed to investigate the relationships among body weight, body mass index (BMI=kg/m(2)), change in a depression rating scale, and change in a functional scale with fluoxetine treatment for hospitalized patients with major depressive disorder (MDD).', 'A total of 131 acutely ill inpatients with MDD were enrolled to receive 20mg of fluoxetine daily for 6 weeks. The 17-item Hamilton Depression Rating Scale (HAMD-17) for symptom and the Work and Social Adjustment Scale (WSAS) for functioning were assessed at weeks 0, 1, 2, 3, 4, and 6. Remission was defined as a score of7 on the HAMD-17 at endpoint. Body weight, body length, and BMI were measured at baseline. Pearson correlation coefficients (r) were calculated among body weight, BMI, HAMD-17 score change, and WSAS score change.', 'Of the 131 participants, 126 (96.2%) had at least one post-baseline assessment and were included in the analysis. Significant differences in body weight and BMI existed between remitters and nonremitters. There were statistically significant relationships among baseline body weight, baseline BMI, HAMD-17 score change, and WSAS score change at end point.

Question: In the Microbicide Trial Network MTN-003 (VOICE) study, a Phase IIB pre-exposure prophylaxis trial of daily oral or vaginal tenofovir (TFV), product adherence was poor based on pharmacokinetic (PK) drug detection in a random subsample. Here, we sought to compare behavioural and PK measures of adherence and examined correlates of adherence misreporting.', 'We included participants with PK and behavioural data from VOICE random subsample. Behavioural assessments included face-to-face interviews (FTFI), audio computer-assisted self-interviewing (ACASI) and pharmacy-returned product counts (PC). TFV concentrations < 0.31 ng/mL in plasma (oral group) and < 8.5 ng/swab in vaginal group were defined as "PK non-adherent." Logistic regression models were fit to calculate the combined predictive ability of the behavioural measures as summarized by area under the curve (AUC). Baseline characteristics associated with over-reporting daily product use relative to PK measures was assessed using a Generalized Linear Mixed Model.', 'In this random adherence cohort of VOICE participants assigned to active products, (N = 472), PK non-adherence was 69% in the oral group (N = 314) and 65% in the vaginal group (N = 158). Behaviourally, 10% of the cohort reported low/none use with any behavioural measure and accuracy was low ( 43%). None of the regression models had an AUC > 0.65 for any single or combined behavioural measures. Significant (p < 0.05) correlates of over-reporting included being very worried about getting HIV and being unmarried for the oral group; whereas for the vaginal group, being somewhat worried about HIV was associated with lower risk of over-reporting.
