Question: To study the long-term effects of selegiline in monotherapy and in combination with levodopa in the early phase of Parkinson disease (PD).', "One hundred fifty-seven de novo PD patients were randomized in a double-blind, placebo-controlled study of 7 years' duration. In the monotherapy part, selegiline significantly delayed the initiation of levodopa therapy vs placebo. The authors now report the results from the combination part of the study, in which 140 patients received selegiline or placebo in addition to individually tailored levodopa therapy.", 'Compared with placebo, selegiline slowed the progression of disease disability as measured by the Unified Parkinson Disease Rating Scale (UPDRS) total score (p = 0.003) or by motor (p = 0.002) and Activities of Daily Living (p = 0.0002) subscores. After 5 years in combination therapy, the mean difference in the UPDRS total score was nearly 10 points, with patients receiving placebo having 35% higher scores. Simultaneously, patients receiving placebo needed progressively higher doses of levodopa than patients receiving selegiline; after 5 years, the mean dosage of levodopa was 19% higher with placebo than with selegiline (p = 0.0002). Considering the entire (monotherapy and combination therapy) 7-year study time, there was a trend for selegiline to delay the start of wearing-off fluctuations (hazard ratio 0.55, p = 0.08). In both phases of the study, selegiline was safe and well tolerated.

Answer: Does selegiline slow the progression of the symptoms of Parkinson disease?


Question: Various techniques and devices have been proposed for tricuspid valve (TV) repair in patients with tricuspid regurgitation (TR). However, residual or recurrent TR is not uncommon occurring in 20% to 30% of patients. This study reports first experiences with a new three-dimensional annuloplasty ring.', 'We retrospectively reviewed 200 consecutive patients who underwent TV repair for functional TR with the Contour 3D annuloplasty ring (Medtronic, Minneapolis, MN) from December 2010 to February 2013 at our institution. The follow-up is 98% complete (mean 1.0 ±\xa00.7 years; cumulative total 189 patient-years).', 'Mean age was 70.4 ± 9.1 years and the median logistic European system for cardiac operative risk was 7%. Sixty-nine percent of the patients were in New York Heart Association class III/IV. Echocardiography documented moderate or severe TR in 97.5% of the patients, with a mean annulus diameter of 45.1 ± 4.9 mm; 93.5% of the patients underwent a combined procedure, and 20.5% an urgent or emergent operation. The 30-day mortality was 6%. The preoperative TR grade was reduced from 2.45 ± 0.53 to 0.77 ± 0.54 (p < 0.001). At hospital discharge residual II TR or greater was present in 4.3% of the patients. Freedom from recurrent II TR or greater at 2\xa0years was 90.9% ± 4.2% and freedom from TV-related reoperations at 2 years was 98.5% ± 1.0%. No case of\xa0ring dehiscence occurred. Fourteen patients (7%) required a permanent pacemaker implantation for atrioventricular block.

Answer: Does early experience with a new three-dimensional annuloplasty ring for the treatment of functional tricuspid regurgitation?


Question: To investigate, at a population level, whether a family history of abdominal aortic aneurysm (AAA) is independently related to increased aortic diameter and prevalence of AAA in men, and to elucidate whether the mean aortic diameter and the prevalence of AAA are different between participants with male and female relatives with AAA.', 'Observational population-based cross-sectional study.', '18,614 male participants screened for AAA in the VIVA-trial 2008-2011 with information on both family history of AAA and maximal aortic diameter.', 'Standardized ultrasound scan measurement of maximum antero-posterior aortic diameter. Family history obtained by questionnaire. Multivariate regression analysis was used to test for confounders: age, sex, smoking, comorbidity and medication.', 'From the screened cohort, 569 participants had at least one first degree relative diagnosed with AAA, and 38 had AAA. Participants with a family history of AAA (+FH) had a significantly larger mean maximum aortic diameter (20.50 mm) compared with participants without family history of AAA (-FH) (19.07 mm, p < .0001), and +FH with female relatives with AAA had significantly larger mean maximum aortic diameter (21.8 mm) than +FH with male relatives (19.9 mm, p = .007). Furthermore the prevalence of AAA was significantly higher among +FH (6.7%) compared with -FH (3.0%) with an odds ratio (OR) of 2.2 (95% CI: 1.6 to 3.2, p < .001) and +FH with female relatives with AAA had a more than two and a half times increased prevalence of AAA compared with +FH with male relatives with AAA with an OR of 2.65.

Answer:
Is abdominal aortic diameter increased in males with a family history of abdominal aortic aneurysms : results from the Danish VIVA-trial?
