Preoperatory Anxiety in Patients Undergoing Cardiac Surgery.

2019

Anxiety is a feeling of discomfort produced in face of an unknown event, as an impending cardiac surgery, that can lead to inconveniences in the intervention and subsequent recovery. Being the purpose of this research to analyze pre-surgical anxiety, a descriptive cross-sectional study among patients undergoing cardiac surgery was carried out. Data about sociodemographic variables were collected and the level of anxiety prior to surgery was assessed using the STAI-S scale. Subsequently, descriptive data analyses were performed, relationships among variables were analyzed, and a binary logistic regression model was developed in order to analyze the role of the variables involved in the devel…

Multi Regression Analysis of Skin Temperature Variation During Cycling Exercise

2017

In the last years, infrared thermography (IRT) has become a popular technique to determine human skin temperature during exercise [1–3]. IRT presents several applications in sport science such as the detection of injury, the thermophysiology assessment, the sport clothing assessment/design, or its application in equestrian sport, among others [3]. However, IRT in sports is still a recent topic and there are many fundamental discussions concerning different methodological aspects, being one of them the analysis of the thermal data [4].

Kinetik von Indozyaningrün (ICG) und adjuvanter Einsatz zur transpupillaren Thermotherapie (TTT) pigmentarmer kleiner Aderhautmelanome

2004

BACKGROUND To determine the efficacy of intravenous indocyanine green (ICG) as an adjuvant to TTT for hypopigmented choroidal melanomas. PATIENTS AND METHODS ICG kinetics in melanoma tissue were evaluated by taking standardized ICG angiograms in 28 eyes with small choroidal melanomas. In a prospective non-randomized analysis 12 eyes with hypopigmented choroidal melanomas (posterior to the equator with thickness </= 4.5 mm) were treated with the TTT standard protocol developed by an intravenous injection of 100 mg ICG in 10 ml aqueous solvent 2 minutes after starting TTT. These eyes were followed-up for at least 22 months (mean 29). RESULTS Pharmacokinetic analyses revealed the onset of fluo…

Usefulness of the Neutrophil-to-Lymphocyte Ratio as a Predictor of Pneumonia and Urinary Tract Infection Within the First Week After Acute Ischemic S…

2021

Background: A high Neutrophil-to-Lymphocyte ratio (NLR) in patients with acute ischemic stroke (AIS) has been associated with post-stroke infections, but it's role as an early predictive biomarker for post-stroke pneumonia (PSP) and urinary tract infection (UTI) is not clear. Aim: To investigate the usefulness of NLR obtained within 24 h after AIS for predicting PSP and UTI in the first week. Methods: Clinical and laboratory data were retrieved from the University Hospital Brussels stroke database/electronic record system. Patients were divided into those who developed PSP or UTI within the first week after stroke onset and those who didn't. Receiver operating characteristics (ROC) curves a…

Kidney Disease Management in the Hospital Setting: A Focus on Inappropriate Drug Prescriptions in Older Patients

2021

Aging with multimorbidity and polytherapy are the most significant factors that could led to inappropriate prescribing of contraindicated medications in patients with chronic kidney disease (CKD). The aim of this study was to evaluate the prescriptions of contraindicated drugs in older adults in CKD and to identify their associated factors in a hospital context. An observational retrospective study was carried out considering all patients ≥65 years with at least one serum creatinine value recorded into the REPOSI register into 2010–2016 period. The estimated glomerular filtration rate (eGFR) was applied to identify CKD. A descriptive analysis was performed to compare demographic and clinica…

Concomitant history of cancer in acute pulmonary embolism is connected with poorer outcome

2015

Abstract Purpose: Cancer increases the risk of venous thromboembolism (VTE) substantially. VTE is connected with poorer outcome in cancer patients. The aim of our study was to investigate the impact of cancer on the severity and short-term outcome of pulmonary embolism (PE). Methods: We retrospectively analyzed the data of 182 patients with confirmed PE. PE patients were subdivided in the group with concomitant active cancer disease or history of cancer or in the group without cancer. Groups were compared with Wilcoxon–Mann–Whitney Test. Logistic regression models were calculated to investigate the association between cancer and several parameters such as age and PE severity status as well …

Tomographic left ventricular volume determination in the presence of aneurysm by three-dimensional echocardiographic imaging. I: Asymmetric model hea…

1996

To improve the accuracy of measurements of left ventricular volume in the presence of an aneurysm, we used three-dimensional echocardiographic imaging to analyze the shape of left ventricles in 23 asymmetric model hearts with eccentric aneurysms of different sizes, shapes, and localizations. A standard 3.75 MHz ultrasound probe with a rotation motor device was used to obtain a three-dimensional data set. By rotating the probe stepwise 1 degree, 180 radial ultrasound pictures were digitized. On the basis of the three-dimensional data set, the following parameters were determined and compared with the dimensions of the model hearts obtained by direct measurement: total left ventricular volume…

Validation of motor and functional scales for the evaluation of adult patients with 5q spinal muscular atrophy

2021

ABSTRACTObjectiveTo assess in adult spinal muscular atrophy (SMA) patients the construct validity and responsiveness of several outcome measures.MethodsPatients older than 15 years and followed-up at least for 6 months, between October 2015 and August 2020, with one motor function scale (Hammersmith Functional Motor Scale Expanded, HFMSE; Revised Upper Limb module, RULM) in five referral centers were included. Bedside functional scales (Egen Klassification, EK2; Revised Amyotrophic Lateral Sclerosis Functional Rating Scale, ALSFRS-R) were also collected when available. Correlations and regression models were performed to evaluate the construct validity. The monthly slopes of change were use…

Respiratory snorkel and valve system for breath-by-breath gas analysis in swimming

2003

The present study aimed to compare a standard facemask (CM) and a newly modified swimming snorkel and valve system (SV) for breath-by-breath (BxB) gas analysis (K4 b2, Cosmed, Rome, Italy), and to validate the system under controlled laboratory conditions before being used in swimming. Nine healthy males performed two bouts of a stepwise exercise on an electrically braked stationary bicycle on separate days. Ventilatory and gas exchange parameters were analyzed using the same BxB portable system, with subjects breathing alternatively through the two different valves. Agreement between both methods was evaluated by Passing-Bablok regression analysis. The gas exchange values measured using th…
