Predictive factors of severity and persistence of oropharyngeal dysphagia in sub-acute stroke.
2020
Purpose: This study aims to understand the factors contributing to the severity of oropharyngeal dysphagia and its persistence in the sub-acute phase of stroke. Methods: We retrospectively collected the data of all the patients suffering from a stroke in the last year. The severity of stroke was reported according to the NIHSS score. All the patients were evaluated with the Dysphagia Risk Score and with a FEES. We classified the Dysphagia Risk Score and FEES results using the PAS score and ASHA-NOMS levels. The data were analysed statistically with ANOVA test, Student’s t test and Pearson’s correlation coefficient. Results: A series of 54 patients were evaluated. The ANOVA test did not find…
Information transfer and information modification to identify the structure of cardiovascular and cardiorespiratory networks
2017
To fully elucidate the complex physiological mechanisms underlying the short-term autonomic regulation of heart period (H), systolic and diastolic arterial pressure (S, D) and respiratory (R) variability, the joint dynamics of these variables need to be explored using multivariate time series analysis. This study proposes the utilization of information-theoretic measures to measure causal interactions between nodes of the cardiovascular/cardiorespiratory network and to assess the nature (synergistic or redundant) of these directed interactions. Indexes of information transfer and information modification are extracted from the H, S, D and R series measured from healthy subjects in a resting…
Need to evaluate the performance of real-time PCR assays for the quantitation of cytomegalovirus DNA load in lower respiratory tract specimens
2013
There is an increasing appreciation for the potential clinical value of the quantitation of cytomegalovirus (CMV) DNA in the lower respiratory tract in critically ill patients lacking canonical immunosuppression, in view of the possible pathogenic role of CMV in these patients [1]. No data have been published on the analytical performance of real-time PCR assays for this purpose. We present our data on the performance of the COBAS® AmpliPrep/COBAS® TaqMan CMV PCR Assay (Roche Diagnostics, Mannheim, Germany) for the quantitation of CMV DNA in tracheal aspirates (TA). This CMV PCR assay has been approved recently by the US Food and Drug Administration for use with plasma specimens [2]. We cho…
Therapy with non-invasive ventilation in patients with obstructive sleep apnoea: effects on atherogenic lipoprotein phenotype.
2009
Patients with obstructive sleep apnoea are at increased risk of atherosclerotic morbidity and mortality. Abnormalities in lipid metabolism that occur in response to chronic intermittent hypoxia in patients with sleep-disordered breathing may increase the cardiovascular risk in an already susceptible population. Atherogenic lipoprotein phenotype and small, dense LDL have an independent predictive role for future cardio- and cerebro-vascular events in patients with the metabolic syndrome. Therefore, testing the hypothesis that therapy of obstructive sleep apnoea may reduce atherogenic lipoprotein phenotype might have significant clinical implications. We suggest that abolition of obstructive …
Computertomographische Funktionsuntersuchung der Lunge nach einseitiger Lungentransplantation mit axialer und koronarer Akquisition
1996
After single-lung transplantation in a patient suffering from obstructive emphysema lung function parameters worsened during follow-up. To complement the routine high-resolution CT (HRCT) scans acquired in inspiration, additional scans were obtained to evaluate regional lung function. The comparison of HRCT scans acquired in inspiration and in expiration revealed different ventilation conditions of both lungs, continuous acquisition in a single slice (dynamic multiscan acquisition) in the axial and coronal plane demonstrated mediastinal shifting and the movement of the diaphragm during the whole breathing cycle. Both modalities can provide important information concerning regional differenc…
Preparation, Execution and Experience: A Multivariate Evaluation of ANS-SNS Patterns
1985
Aims to verify with multivariate methods how autonomic-somatic changes (composed by skin conductance, heart rate, pulse amplitude, respiration, blood volume and flexor, frontal and orbicutaris oris EMG-measures) from specific patterns according to event-related demands both during (or after) and before events when contentual and temporal knowledge allowing preparation is varied.
Swallowing impairment in neurologic disorders: The role of videofluorographic swallowing study
2018
Patients with neurologic diseases almost inevitably develop various degrees of swallowing disorders during their life. Dysphagia is one of the main negative prognostic factors in this class of patients, leading to severe morbidity (i.e. aspiration pneumonia, dehydration, malnutrition, and life quality deterioration) and to a noticeable increase in public health spending. Videofluorographic swallowing study is considered the gold standard technique for swallowing impairment assessment. It is aimed at early identification of the risk of aspiration, definition of the kind and grade of dysphagia, and an indication to suspend oral nutrition and adopt other feeding strategies, and define when the…
Variability in recording and scoring of respiratory events during sleep in Europe: a need for uniform standards.
2015
Abstract: Uniform standards for the recording and scoring of respiratory events during sleep are lacking in Europe, although many centres follow the published recommendations of the American Academy of Sleep Medicine. The aim of this study was to assess the practice for the diagnosis of sleep-disordered breathing throughout Europe. A specially developed questionnaire was sent to representatives of the 31 national sleep societies in the Assembly of National Sleep Societies of the European Sleep Research Society, and a total of 29 countries completed the questionnaire. Polysomnography was considered the primary diagnostic method for sleep apnea diagnosis in 10 (34.5%), whereas polygraphy was …
I06 Dysphagia In Huntington`s Disease: A Multicenter Study
2014
Background Dysphagia is a common complication of neurogenerative disorders, and a leading cause of death due to aspiration pneumonia. Little is known about the frequency and the characteristics of dysphagia in HD. Well-balanced strategies for treatment and prevention of dysphagia in HD are lacking. Objetives To determine the prevalence of dysphagia in HD. Methods National, multicenter, observational, cross-sectional Study (Spanish EHDN). Dysphagia was assessed using the questionnaire EAT-10 (eating assessment tool), caregiver burden using the SumaCare, functional capacity using the TFC score, disease severity using the Unified HD Rating Scale (UHDRS), psyquiatric status (PBA-s), nutritional…
Percutaneous tracheostomy in COVID patients. Experience in our hospital center after one year of pandemic and review of the literature
2021
Background The pandemic caused by SARS-COV-2 has caused an increase in the need of tracheostomies in patients affected with respiratory distress syndrome. In this article we report our experience during a year of pandemic, we develop our surgical technique to perform percutaneous tracheostomy with the patient in apnea and we compare our results with those of other centers through a bibliographic review. Material and Methods A one-year retrospective clinical study was carried out on tracheotomies performed on patients admitted to the intensive care unit with severe SARS-CoV-2, with difficulty for ventilation or weaning. The technique performed was percutaneous, with fibroscopic control throu…
