RIPHeart (Remote Ischemic Preconditioning for Heart Surgery) Study: Myocardial Dysfunction, Postoperative Neurocognitive Dysfunction, and 1 Year Foll…

2018

Background Remote ischemic preconditioning ( RIPC ) has been suggested to protect against certain forms of organ injury after cardiac surgery. Previously, we reported the main results of RIPHeart (Remote Ischemic Preconditioning for Heart Surgery) Study, a multicenter trial randomizing 1403 cardiac surgery patients receiving either RIPC or sham‐ RIPC . Methods and Results In this follow‐up paper, we present 1‐year follow‐up of the composite primary end point and its individual components (all‐cause mortality, myocardial infarction, stroke and acute renal failure), in a sub‐group of patients, intraoperative myocardial dysfunction assessed by transesophageal echocardiography and the incidenc…

The effects of transdermal testosterone and oestrogen therapy on dry eye in postmenopausal women: a randomised, placebo-controlled, pilot study

2016

Aims Sex hormones could provide a future treatment avenue for dry eye post menopause. However, there are few well-controlled studies. This study investigates the impact of testosterone and oestrogen on dry eye symptoms and signs in postmenopausal women. Methods A randomised double-blind placebo-controlled pilot study was conducted involving 40 women with dry eye (age 63.9±5.1 years, 13.2±6.3 years post menopause). Ten women were assigned to each of four treatment groups: transdermal testosterone, oestradiol, testosterone/oestradiol combination and placebo. Assessment at baseline and after 8 weeks: ocular symptoms, tear osmolarity, tear stability, tear secretion, meibomian gland assessment, …

Effects of ipriflavone on bone mass and calcium metabolism in postmenopausal osteoporosis.

1992

Recently it has been demonstrated that ipriflavone (IP), an isoflavone derivative, is able to increase bone mass in patients with established postmenopausal osteoporosis (PMO). Here we present a preliminary report of a 2-year multicenter, double-blind, placebo-controlled clinical study performed in order to evaluate the efficacy and tolerability of IP in PMO. A large number of patients with PMO, referred to 12 Italian centers, was randomly divided into 2 groups and treated with oral IP (600 mg/day) or placebo (Pl). All patients received an oral Ca supplement (1 g/day). One hundred and twenty six patients completed 1 year of the study. Bone mineral density (BMD) of the distal radius, measure…

Impact of the pupil size – central optical zone diameter relationship on visual performance in aspheric multifocal contact lenses

2020

Abstract Purpose To determine the impact of different central optical zone diameters (COZDs), obtained from pupil size, on the visual performance of presbyopic subjects fitted with centre-distance simultaneous-image multifocal contact lenses (SIMCLs). Methods Thirty-two presbyopic volunteers, between 45–58 years of age, participated in this prospective, controlled, double-blind study. Subjects were fitted with 5 centre-distance SIMCLs of variable COZD, determined from the measurement of pupil size under photopic light conditions and corresponding to 60, 70, 80, 90 and 100 % of pupil diameter. Subjects visual performance was evaluated through the measurement of distance, intermediate and nea…

Definition of the Rectum An International, Expert-based Delphi Consensus

2019

Mini: A radiological, anatomic distinction between the rectum and sigmoid colon was agreed by consensus of international experts in rectal cancer using the Delphi Technique. Use of this landmark, “the sigmoid take-off,” may harmonize efforts in research and clinical practice to improve patient outcomes. Background: The wide global variation in the definition of the rectum has led to significant inconsistencies in trial recruitment, clinical management, and outcomes. Surgical technique and use of preoperative treatment for a cancer of the rectum and sigmoid colon are radically different and dependent on the local definitions employed by the clinical team. A consensus definition of the rectum…

Use in clinical practice of an automated screening method of diabetic retinopathy that can be derived using a diagnostic artificial intelligence syst…

2020

Abstract Background and Objective To compare the diagnostic performance of an autonomous diagnostic artificial intelligence (AI) system for the diagnosis of derivable diabetic retinopathy (RDR) with manual classification. Materials and Methods Patients with type 1 and type 2 diabetes participated in a diabetic retinopathy (RD) screening program between 2011–2012. 2 images of each eye were collected. Unidentifiable retinal images were obtained, one centered on the disc and one on the fovea. The exams were classified with th e autonomous AI system and manually by anonymous ophthalmologists. The results of the AI system and manual classification were compared in terms of sensitivity and specif…

Metastatic Versus Osteoporotic Vertebral Fractures on MRI: A Blinded, Multicenter, and Multispecialty Observer Agreement Evaluation.

2020

Background: MRI is assumed to be valid for distinguishing metastatic vertebral fractures (MVFs) from osteoporotic vertebral fractures (OVFs). This study assessed (1) concordance between the image-based diagnosis of MVF versus OVF and the reference (biopsy or follow-up of >6 months), (2) interobserver and intraobserver agreement on key imaging findings and the diagnosis of MVF versus OVF, and (3) whether disclosing a patient’s history of cancer leads to variations in diagnosis, concordance, or agreement. Patients and Methods: This retrospective cohort study included clinical data and imaging from 203 patients with confirmed MVF or OVF provided to 25 clinicians (neurosurgeons, radiologists…

Prevention of feeding tube dislodgement with the Wiesbaden rein: a case series.

2009

We describe initial experience with the use of a new fixation method (Wiesbaden rein), which has been developed to prevent dislodgement of feeding tubes in the gastrointestinal tract. The Wiesbaden rein has been used in three patients without complication. In none of the patients was dislodgement or malfunction of the feeding tube observed. Therefore, the use of the Wiesbaden rein might prevent dislodgement of feeding tubes. Clinical trials are required before this new method can be recommended for general use.
