One-year renal and cardiac effects of bisoprolol versus losartan in recently diagnosed hypertensive patients: a randomized, double-blind study.

2009

BACKGROUND AND OBJECTIVES: Hypertension is a significant cause of chronic renal injury and its effective treatment is capable of reducing the rate of renal failure. beta-Adrenoceptor antagonists (beta-blockers) have been reported to induce a deterioration in renal function, while several data have indicated a renoprotective effect of treatment with the angiotensin II type 1 receptor antagonist losartan. Previous studies of the interaction between the selective beta(1)-blocker bisoprolol and kidney function were performed only for short- and medium-term periods. The aim of this study was to compare the antihypertensive efficacy and renal and cardiac haemodynamic effects of bisoprolol with th…

Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial: results up to 4 years from a randomised, multi…

2008

Summary Background Carotid stenting is a potential alternative to carotid endarterectomy but whether this technique is as safe as surgery and whether the long-term protection against stroke is similar to that of surgery are unclear. We previously reported that in patients in the Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial, the rate of any stroke or death within 30 days after the procedure was higher with stenting than with endarterectomy. We now report the results up to 4 years. Methods In this follow-up study of a multicentre, randomised, open, assessor-blinded, non-inferiority trial, we compared outcome after stenting with outcome …

Statin therapy and plasma coenzyme Q10 concentrations—A systematic review and meta-analysis of placebo-controlled trials

2015

Statin therapy may lower plasma coenzyme Q10 (CoQ10) concentrations, but the evidence as to the significance of this effect is unclear. We assessed the impact of statin therapy on plasma CoQ10 concentrations through the meta-analysis of available RCTs. The literature search included selected databases up to April 30, 2015. The meta-analysis was performed using either a fixed-effects or random-effect model according to I(2) statistic. Effect sizes were expressed as weighted mean difference (WMD) and 95% confidence interval (CI). The data from 8 placebo-controlled treatment arms suggested a significant reduction in plasma CoQ10 concentrations following treatment with statins (WMD: -0.44 μmol/…

The clinical use of statistical permutation test methodology: a tool for identifying predictive variables of outcome.

2015

<b><i>Objectives:</i></b> To identify the predictive variables affecting the outcome after radical surgery for bladder cancer by a newer statistical methodology, i.e. nonparametric combination (NPC). <b><i>Methods:</i></b> A multicenter study enrolled 1,312 patients who had undergone radical cystectomy for bladder cancer in 11 Italian oncological centers from January 1982 to December 2002. A statistical analysis<b> </b>of their medical history and diagnostic, pathological and postoperative variables was performed using a NPC test. The<b> </b>patients were included in a comprehensive database with medical history and cli…

Cancer-specific survival after radical cystectomy and standardized extended lymphadenectomy for node-positive bladder cancer: prediction by lymph nod…

2009

OBJECTIVE To investigate the associations between different overall or topographically restricted lymph node (LN) variables and cancer-specific survival (CSS) after radical cystectomy (RC) and extended LN dissection (LND) with curative intent in patients with LN-positive bladder cancer. PATIENTS AND METHODS Between 2001 and 2006, 152 patients had RC with standardized extended LND for bladder cancer with curative intent. Patients with positive LNs were stratified according to the median of the LN variables (LNs removed, number of positive LNs, LN density). CSS was related to overall and topographically restricted LN variables, e.g. different levels of LND, and relationships were tested by un…

Liver assessment and biopsy in patients with marked coagulopathy: value of mini-laparoscopy and control of bleeding.

2003

Evaluation of liver disease in patients with a high risk of postbiopsy bleeding presents a diagnostic challenge. Mini-laparoscopy offers the possibility of coagulation of biopsy site and the additional advantage of macroscopic liver assessment. We wished to assess the value and safety of mini-laparoscopy with guided biopsy as a diagnostic approach in patients in whom percutaneous liver biopsy is considered contraindicated because of a marked coagulopathy.We investigated 61 consecutive patients with marked coagulopathy (prolonged international normalized ratio1.5, thrombocytopenia50/nl, or both; von Willebrand's disease/hemophilia). Diagnostic mini-laparoscopy with visually guided liver biop…

Predictive role of capillaroscopic skin ulcer risk index in systemic sclerosis: A multicentre validation study

2012

IntroductionThe early detection of systemic sclerosis (SSc) patients at high risk of developing digital ulcers could allow preventive treatment, with a reduction of morbidity and social costs. In 2009, a quantitative score, the capillaroscopic skin ulcer risk index (CSURI), calculated according to the formula ‘D×M/N2’, was proposed, which was highly predictive of the appearance of scleroderma digital ulcers within 3 months of capillaroscopic evaluation.ObjectivesThis multicentre study aims to validate the predictive value and reproducibility of CSURI in a large population of SSc patients.MethodsCSURI was analysed in 229 unselected SSc patients by nailfold videocapillaroscopy (NVC). All pati…

Androgen receptors and testosterone in men—Effects of protein ingestion, resistance exercise and fiber type

2007

The purpose of this study was to examine the impact of protein ingestion on circulating testosterone and muscle androgen receptor (AR) as well as on insulin-like growth factor-I (MGF and IGF-IEa) responses to a resistance exercise (RE) bout in (57-72 year) men. Protein (15 g whey) (n=9) or placebo (n=9) was consumed before and after a RE bout (5 sets of 10 repetition maximums), and vastus lateralis muscle biopsies were taken pre, 1 and 48 h post-RE. The protein ingestion blunted the RE-induced increase in serum free and total testosterone while the RE bout significantly increased muscle AR mRNA levels in older men (P<0.05). However, protein ingestion did not significantly affect AR mRNA or …
