Non-invasive ventilation in postoperative patients: A systematic review

2010

Background: Postoperative pulmonary complications, generally defined as any pulmonary abnormality occurring in the postoperative period, are still a significant issue in clinical practice increasing hospital length of stay, morbidity and mortality. Non-invasive ventilation (NIV), primarily applied in cardiogenic pulmonary edema, decompensated COPD and hypoxemic pulmonary failure, is nowadays also used in perioperative settings. Objective: Investigate the application and results of preventive and therapeutic NIV in postsurgical patients. Design: A systematic review. Data sources: Medical literature databases were searched for articles about "clinical trials," "randomized controlled trials" a…

Postural Adaptations in Preadolescent Karate Athletes Due to a One Week Karate Training Camp

2013

Abstract The aim of this study was to investigate the effect of an increasing number of training hours of specific highintensity karate training on postural sway in preadolescent karate athletes. Seventy-four karatekas were randomly assigned to 1 of 2 groups: Karate Group (KG=37): age 10.29±1.68 yrs; or Control Group (CG= 37): age 10.06±1.77 yrs. The KG performed two sessions per day for 1 week in total, while the CG performed only 3 sessions during the same period. The center-of-pressure length (COPL) and velocity (COPV) were recorded under four different experimental conditions: open eyes (EO), closed eyes (EC), open eyes monopodalic left (EOL), open eyes monopodalic right (EOR), pre as w…

Patient Profiling Based on Spectral Clustering for an Enhanced Classification of Patients with Tension-Type Headache

2020

Profiling groups of patients in clusters can provide meaningful insights into the features of the population, thus helping to identify people at risk of chronification and the development of specific therapeutic strategies. Our aim was to determine if spectral clustering is able to distinguish subgroups (clusters) of tension-type headache (TTH) patients, identify the profile of each group, and argue about potential different therapeutic interventions. A total of 208 patients (n = 208) with TTH participated. Headache intensity, frequency, and duration were collected with a 4-week diary. Anxiety and depressive levels, headache-related burden, sleep quality, health-related quality of life, pre…

Foot Temperature Assessment

2016

Thermographic studies of the foot can be very useful in 3 different ways: in preventing injury, in analyzing sporting technique and in assessing the effects of footwear and clothing. The aim of this chapter is to discuss several methodological points concerning the thermal analysis of the foot using infrared thermography, as well as to discuss how it can be applied to the science of sports, both in areas already researched and those as yet uninvestigated.

Background of Physiology in the Pulmonary Circulation

1980

This paper has to be considered as an introduction to the physiology of pulmonary circulation: it can only introduce to some aspects of this topic which will be dealt with in more detail in the following presentations and actually are widely discussed in the literature.

Ventrolateral Compression of the Brain Stem in Essential Hypertension: MR Angiography Study

1997

Our purpose was to evaluate neurovascular compression at the level of ventrolateral medulla and NVC with the IXth and the Xth cranial nerves in patients with essential hypertension and in healthy volunteers using high resoluted Spoiled Recalled Gradient Echo (SPGR) sequences, allowing the detection of stationary tissues and moving spins. Thirty patients (19 men and 11 women) with essential hypertension were examined. Patient's ages ranged from 24 to 64 years-old (mean age was 48 y.o.). Patients older than 65 were excluded. The average of systolic blood-pressure of hypertensive patients was 183 ± 10 mmHg, while the diastolic pressure was 98 ± 10.5 mmHg. In conclusion, we consider axial sing…

Soft Tissue Management and Postoperative Care

2014

The acute compartment syndrome is a limb-threatening complication. Although the diagnosis is primarily based on clinical evaluation, intracompartmental pressure monitoring may be required in specific situations. Surgical decompression is the only adequate treatment. Any delay in surgical management increases the risk of late sequellae.

An exploratory study of two Caco-2 cell models for oral absorption: A report on their within-laboratory and between-laboratory variability, and their…

2010

In 2005, the European Centre for the Validation of Alternative Methods (ECVAM) sponsored a study aimed at evaluating the reproducibility (between-laboratory and within-laboratory variability) and the predictive capacity of two in vitro cellular systems — the Caco-2/ATCC parental cell line and the Caco-2/TC7 clone — for estimating the oral fraction absorbed (Fa) in humans. Two laboratories, both of which had experience with Caco-2 cultures, participated in the study. Ten test chemicals with documented in vivo oral absorption data were selected. Atenolol, cimetidine and propranolol were included as reference compounds for low, medium and high intestinal absorption, respectively. Transport ex…

Systematic analysis of esophageal pressure topography in high-resolution manometry of 68 normal volunteers

2013

Summary The introduction of high-resolution manometry (HRM) has been a significant advance in esophageal diagnostics. Normative values however are currently based upon a single set of published reference values, and multiple new metrics have been added over the past several years. Our goal was to provide a second set of ‘normal-values’ and to include all current metrics suggested by the 2012 Chicago classification. Sixty-eight subjects without foregut symptoms or previous surgery (median age 25.5 years, ranging from 20–58 years, 53% female) underwent esophageal motility assessment via an established standardized protocol. Normative thresholds were calculated for esophago-gastric junction (E…
