ESRA19-0640 The effect of intravenous dexamethasone on pain relief, blood glucose and lactate levels after hip atheroplasty

2019

Background and aims Dexamethasone provides anti-inflammatory and analgesic effect, but induces hyperglycemia and may increase serum lactate. the aim was to determine the effect of dexamethasoneon analgesia, blood glucose and lactate after hip arthroplasty. Methods This prospective randomized study includes 32 patients undergoing hip replacement. It was provided SA and patients received multimodal analgesia. the experimental group received Dexamethasone 8 mg i/v before surgery and 4 mg i/v in a 6 and 12 hours after the first dose. the control group did not receive any glucocorticoids. Blood glucose and lactate were measured before surgery,at 18:00 and 6:00 on the POD1. Patients filled in a p…

Metabolic impact of adult-onset, isolated, growth hormone deficiency (AOiGHD) due to destruction of pituitary somatotropes.

2011

Growth hormone (GH) inhibits fat accumulation and promotes protein accretion, therefore the fall in GH observed with weight gain and normal aging may contribute to metabolic dysfunction. To directly test this hypothesis a novel mouse model of adult onset-isolated GH deficiency (AOiGHD) was generated by cross breeding rat GH promoter-driven Cre recombinase mice (Cre) with inducible diphtheria toxin receptor mice (iDTR) and treating adult Cre(+/-), iDTR(+/-) offspring with DT to selectively destroy the somatotrope population of the anterior pituitary gland, leading to a reduction in circulating GH and IGF-I levels. DT-treated Cre(-/-), iDTR(+/-) mice were used as GH-intact controls. AOiGHD im…

RETRACTED ARTICLE: Volume replacement with HES 130/0.4 may reduce the inflammatory response in patients undergoing major abdominal surgery

2003

Objectif : Verifier les effets du remplissage intravasculaire sur la reaction inflammatoire pendant une intervention chirurgicale majeure. Methode : Trente-six patients devant subir une intervention abdominale reglee ont ete repartis au hasard et ont recu soit de l'hydroxyethylamidon a 6 % (poids moleculaire moyen de 130 000 Dalton, degre de substitution de 0,4 ; n = 18, groupe HEA), soit une solution de Ringer-lactate (groupe RL ; n = 18) comme remplissage intravasculaire. Les liquides ont ete administres avant l'operation et, pendant 48 h a l'unite des soins intensifs. Le remplissage vasculaire dependait de parametres physiologiques. Les concentrations seriques d'interleukine (IL-6, IL-8 …

Aortic valve disease: follow-up of a group of patients undergone to aortic valve replacement.

Minimally invasive aortic valve surgery

2016

Aortic valve disease is a prevalent disorder that affects approximately 2% of the general adult population. Surgical aortic valve replacement is the gold standard treatment for symptomatic patients. This treatment has demonstrably proven to be both safe and effective. Over the last few decades, in an attempt to reduce surgical trauma, different minimally invasive approaches for aortic valve replacement have been developed and are now being increasingly utilized. A narrative review of the literature was carried out to describe the surgical techniques for minimally invasive aortic valve surgery and report the results from different experienced centers. Minimally invasive aortic valve replacem…

A multicentre European registry to evaluate the Direct Flow Medical transcatheter aortic valve system for the treatment of patients with severe aorti…

2016

Aims Our aim was to assess the clinical outcomes of the Direct Flow Medical Transcatheter Aortic Valve System (DFM-TAVS), when used in routine clinical practice. Methods and results This is a prospective, open-label, multicentre, post-market registry of patients treated with DFM-TAVS according to approved commercial indications. Echocardiographic and angiographic data were evaluated by an independent core laboratory and adverse events were adjudicated and classified according to VARC-2 criteria by an independent clinical events committee. The primary endpoint was freedom from all-cause mortality at 30 days post procedure. Secondary endpoints included procedural, early safety and efficacy en…

Incidence, Predictive Factors, and Prognostic Impact of Silent Atrial Fibrillation After Transcatheter Aortic Valve Implantation.

2018

New onset atrial fibrillation post-transcatheter aortic valve implantation (TAVI) is common and is associated with adverse outcomes. However, silent atrial fibrillation (AF) is poorly documented in the context. This study sought to evaluate the incidence, predictive factors, and prognostic value of Silent AF post-TAVI. All the consecutive patients with TAVI were prospectively analyzed by continuous electrocardiogram monitoring≥48 hours after implantation. Silent AF was defined as asymptomatic episodes lasting at least 30 seconds. The population was divided into 3 groups: history of AF, no-AF, and silent AF. Among the 206 patients implanted with TAVI, 19 (16.1%) developed silent AF. Compared…

TAVI imaging: over the echocardiography

2020

Aortic valve stenosis (AS) is a common valvular heart disease. Recently, transcatheter aortic valve implantation (TAVI) has changed the treatment of severe AS in elderly patients with contraindications to traditional surgical replacement. Echocardiography is conventionally used as the first imaging modality to assess the presence and severity of AS and to provide anatomical and functional information. Nowadays, imaging techniques play a crucial role in the planning of TAVI to define suitable candidates. Computed tomography (CT) is essential to display the anatomy of the aortic valve complex (including aortic annulus, Valsalva sinuses, coronary arteries ostia, sinotubular junction), thoracoa…

Cost effectiveness of aortic valve therapies: a systematic review of the literature

2022

Background: Systematic review on the cost effectiveness of transcatheter aortic valve implantation (TAVI) to standard aortic valve replacement and medical management in high-risk elderly patients with severe aortic stenosis. Evidenced based systematic reviews are the core methodologies in health economics for evaluating cost effectiveness and medical effectiveness. Clarity and transparency of these reports can help to provide health care interventions accurately and reliably. Methods: In accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses, a systematic review on current literature for cost-effectiveness of TAVI, standard aortic valve replacement, and medical m…
