Proprioceptive Neuromuscular Facilitation for Accessory Respiratory Muscles Training in Patients After Ischemic Stroke

2019

This study focused on how pulmonary function is affected by proprioceptive neuromuscular facilitation (PNF) of accessory respiratory muscles in the chronic post-stroke phase. The study involved patients who had had ischemic stroke 6 months or more before the PNF treatment investigated. The objective was to define the effect of PNF on bioelectrical resting and maximum activity of the accessory muscles. Patients were randomly assigned to PNF treatment and just positioning treatment as a reference for comparison; 30 patients each. Electromyography of accessory muscles was investigated before and after physiotherapeutic treatments. We found that there was a greater reduction in EMG activity in …

Optimised lyophilisation-based method for different biomolecule single-extractions from the same rat brain sample: Suitability for RNA and protein ex…

2019

Abstract Background Optimisation of tissue processing procedures in preclinical studies reduces the number of animals used and allows integrated multilevel study in the same sample. Multiple extraction of different biomolecules from the same sample has several limitations. New method Using brain samples from rats subjected to ischemic stroke, we combined lyophilisation of flash-frozen tissue, mechanical pulverisation and cryopreservation in a method to optimise tissue handling and preservation for independent RNA or protein single-extract methods, and subsequent RT-qPCR or Western blot analyses. Results Lyophilisation resulted in 70% tissue weight loss. RNA (OD260/280∼1.8) and protein yield…

Implementation plan for stroke telemedicine in the Valencian Region

2016

Stroke telemedicine is a counselling modality that enables care of stroke patients at remote departmental hospitals by specialists at stroke units in reference hospitals. The planning and implementation of a hub-and-spoke telestroke network are complicated. This paper describes the implementation plan of Telestroke in the Valencian Region, Spain. A stroke telemedicine network was installed in the Valencian Region connecting the departmental hospitals with stroke teams, to the 6 public reference hospitals with a stroke unit. The implementation plan included the installation of the stroke telemedicine network with availability of connection over the internet by VPN. Strategies to ensure good …

Antagonists and agonists at the glycine site of the NMDA receptor for therapeutic interventions.

2003

For decades neuroreceptor research has focused on the development of NMDA glycine-site antagonists, after Johnson and Ascher found out in 1987 about the co-agonistic character of this achiral amino acid at the NMDA receptor. Contrary to the inhibitory glycine receptor (glycine(A)) the glycine binding site on the NMDA receptor (glycine(B)) is strychnine-insensitive. A great diversity of diseases showing a disturbed glutamate neurotransmission have been linked to the NMDA receptor. Glycine site antagonists have been investigated for acute diseases like stroke and head trauma as well as chronic ones like dementia and chronic pain.

Outcome after mitral valve operations with depressed left ventricular function.

2012

We retrospectively investigated 42 patients (27 men, 15 women; mean age, 67 years) with severe mitral valve incompetence and endstage cardiomyopathy (ejection fraction <30%) who were operated on between January 2002 and March 2009. Of these, 14 were in New York Heart Association class IV, and 27 were in class III. The etiology was ischemic in 18 patients and idiopathic dilated in 24. Mitral valve repair was performed in 25 patients, and 17 had mitral valve replacement. The mean logistic EuroSCORE was 33.41. The mean follow-up was 44.52 months. There were no perioperative deaths. Three patients died within 30 days postoperatively. Thirty-day mortality was lower than predicted by EuroSCOR…

Recommendations for the management of patients with obstructive sleep apnoea and hypertension.

2013

This article is aimed at addressing the current state-of-the-art in epidemiology, pathophysiology, diagnostic procedures and treatment options for appropriate management of obstructive sleep apnoea (OSA) in cardiovascular (in particular hypertensive) patients, as well as for the management of cardiovascular diseases (in particular arterial hypertension) in OSA patients. The present document is the result of work performed by a panel of experts participating in the European Union COST (Cooperation in Scientific and Technological research) Action B26 on OSA, with the endorsement of the European Respiratory Society and the European Society of Hypertension. In particular, these recommendations …

Long-term performance of the bovine pericardium patch in conventional carotid endarterectomy.

2014

Objective The aim of the study was to analyze long-term results of carotid endarterectomy (CEA) using bovine pericardium patch. Patients and Methods This study is a retrospective analysis of 274 consecutive cases (173 in CEA group and 101 patients in an internal control group of eversion endarterectomy [EEA]) operated between January 2005 and May 2007. Operations were performed according to standard surgical technique. Primary endpoints of the study were 30-day mortality, ipsilateral neurologic event rate, and high-grade restenosis in the long-term follow-up. Results No statistically significance between both groups was found in terms of gender, age, risk factors, medication (statine, plate…

Value of echocardiography in patient follow-up after surgically corrected type A aortic dissection.

2001

Background To identify patients (pts) at risk of late complications, follow-up after surgery for type A aortic dissection is essential. We assessed the value of echocardiography to monitor patients after surgery for type A aortic dissection. Methods 80 out of 108 pts operated between 1989 and 1999 for type A aortic dissection survived surgery. 62 pts with at least one TEE, CT or MRI examinations during follow-up were included in this study. All pts had transthoracic echocardiography (TTE), 53 transesophageal echocardiography (TEE), 51 had CT, and 39 had MRI. Results At the first follow-up, 12 of 48 pts with aortic valve sparing surgery presented with aortic insufficiency >I degrees detected…

Prognostic Value of the 6-Min Walk Test After Open-Heart Valve Surgery: EXPERIENCE OF A CARDIOVASCULAR REHABILITATION PROGRAM

2018

PURPOSE: This single-center retrospective analysis aimed to evaluate the prognostic relevance of 6-min walk test (6MWT) in patients admitted to an in-hospital cardiovascular rehabilitation program after open-heart valve surgery. METHODS: One hundred one patients able to perform a 6MWT within the first week of admission (time after surgery: 16 ± 8 d) were included (age 68 ± 11 y; 55% female; median left ventricular ejection fraction 55% [interquartile range: 50-60]; 51% after aortic valve surgery). Study endpoints were cardiovascular death and the combined outcome of cardiovascular death/cardiac hospitalization. Univariate and multivariate analyses were performed to analyze predictive value …
