Question: The present study investigated how parents and peers interact in promoting or delaying Dutch adolescents' sexual initiation and intention and focused specifically on parents as moderators of peer influence.", "Using a longitudinal design, two waves of online questionnaire data were collected among 900 Dutch adolescents (M = 13.8 years at T1), who were sexually inexperienced at baseline. At T1, participants reported on three types of perceived sexual peer norms: friends' sexual behaviors (descriptive norms), friends' sexual attitudes (injunctive norms), and experienced peer pressure to have sex. They also rated two parenting aspects at T1: the general quality of their relationship with parents and the frequency of sexuality-specific communication with their parents. Six months later, the participants reported on their experience with different sexual behaviors ranging from naked touching or caressing to intercourse and their intention to have sex in the next school year.", "Relationship quality with parents was significantly associated with both outcomes, with a higher relationship quality predicting smaller odds of sexual initiation and less intention to have sex. Two significant interaction effects showed that frequent sexual communication with parents significantly reduced the effects of sexually active friends and experienced peer pressure on adolescents' intention to have sex.

Question: Total bilirubin (TB) was recently recognized as an endogenous anti-inflammatory and anti-oxidant molecule. Uric acid (UA) takes part in cardiovascular diseases by inducing oxidative stress, inflammation, and endothelial dysfunction. We assessed the relationship between serum TB levels, serum UA levels, and inflammatory status assessed by neutrophil-to-lymphocyte ratio (N/L) and arterial stiffness and arterial wave reflection in patients with a clinical diagnosis of coronary artery disease (CAD).', 'We included 145 consecutive patients admitted with stable angina pectoris (SAP) or acute coronary syndrome (ACS). Blood samples were drawn at admission for complete blood count and biochemistry. Non-invasive pulse waveform analysis for the determination of augmentation index (AIx) and carotid-femoral pulse wave velocity (PWV) measurements were performed with the commercially available SphygmoCor system.', 'When patients were divided into tertiles of PWV and AIx, median N/L and median serum UA levels were the highest and mean TB levels were the lowest in the third tertile (p<0.001 for all). AIx and PWV were positively associated with serum UA and N/L and negatively associated with serum TB levels (p<0.001 for all). After adjustments for age, gender, heart rate, systolic blood pressure, and presence of diabetes, significant correlations persisted for N/L, UA, and TB in ACS patients (p<0.05). In the SAP group, TB was significantly negatively correlated with AIx and PWV, and UA was significantly positively correlated with PWV (p<0.05).

Question: FEV6 can be used as a convenient alternative to FVC. The aim of this study was to determine an alternative to the fixed cutoff points of FEV1/FVC <0.70 suitable for FEV1/FEV6 in primary care.', "Pulmonary function testing was conducted on volunteers recruited from 4 community centers in Xi'an, China, between July and August 2012. Participants underwent 3 FVC maneuvers. The maneuver with the best FEV1 was retained. FVC, FEV1, and FEV6 were measured by portable spirometer. The receiver operating characteristic curves that corresponded to the optimal combination of sensitivity and specificity for FEV1/FEV6 were determined. A kappa test was used to compare the agreement between FEV1/FVC and FEV1/FEV6. The positive predictive value and negative predictive value were also calculated.", 'A total of 767 volunteers participated in this study, of whom 297 were male and 470 were female. Considering FEV1/FVC <0.70 as the accepted standard for COPD, the area under the curve was 98% (P < .001), and the FEV1/FEV6 cutoff, corresponding to the greatest sum of sensitivity and specificity, was 0.72. For the total population, the FEV1/FEV6 sensitivity, specificity, positive predictive value, and negative predictive value were 96.9, 98.8, 95.8, and 99.2%, respectively. The agreement between the 2 cutoff points was excellent, and the kappa value was 0.954.
