Evidence of a contralateral motor influence on reciprocal inhibition in man

1992

The role of contralateral movement on both H reflex and reciprocal inhibition was studied. In normal men H reflex was induced by median nerve stimulation. Reciprocal inhibition was achieved through stimulation of the antagonist radial nerve. On this basis the effects of contralateral arm movement were analized. Furthermore the putative influence of exteroceptive origin was also verified by means of digit stimulation. Results showed that contralateral arm movement did not affect H reflex amplitude; on the contrary, it was able to enhance reciprocal inhibition induced by extensors on flexors. Study of cutaneous afferents demonstrated that contralateral digit stimulation failed to elicit modif…

Usefulness of N-terminal pro-B-type natriuretic peptide levels in predicting residual myocardial ischemia in patients with ST elevation acute myocard…

2007

N-terminal pro-b-type natriuretic peptide (NT pro-BNP) is a neurohormone synthesized predominantly in ventricular myocardium. In patients with symptoms of heart failure, elevation in NT pro-BNP accurately identifies ventricular dysfunction. However, NT pro-BNP levels are not specific for ventricular dysfunction in patients who do not have overt symptoms of heart failure, suggesting that other cardiac processes such as myocardial ischemia may also cause elevation in NT pro-BNP. The study was aimed to determine whether NT pro-BNP elevations are associated with myocardial ischemia.One hundred and thirty patients (104 males, 26 females, mean age 61+12 years), with ST elevation acute myocardial …

TLR2 and age-related diseases: potential effects of Arg753Gln and Arg677Trp polymorphisms in acute myocardial infarction.

2008

ABSTRACT Inflammation is a key component of immune system. It is involved in both defense and pathophysiological events maintaining the dynamic homeostasis of host organism. Its function is controlled by innate immunity genes. Both their polymorphisms and environmental conditions give rise to different phenotypes in human population. Proinflammatory genotype may be beneficial in early life but not in old people. With advancing age, indeed, it increases the vulnerability and the intensity to inflammatory reactions responsible for the chronic inflammatory diseases, such as atherosclerosis and myocardial infarction (MI). Several studies have looked for detecting a genetic risk profile that mig…

Dosage individualization of erythropoietin using a profile-dependent support vector regression

2003

The external administration of recombinant human erythropoietin is the chosen treatment for those patients with secondary anemia due to chronic renal failure in periodic hemodialysis. The objective of this paper is to carry out an individualized prediction of the EPO dosage to be administered to those patients. The high cost of this medication, its side-effects and the phenomenon of potential resistance which some individuals suffer all justify the need for a model which is capable of optimizing dosage individualization. A group of 110 patients and several patient factors were used to develop the models. The support vector regressor (SVR) is benchmarked with the classical multilayer percept…

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

2023

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics,…

[Prevalence of pericardial effusion in subjects with rheumatoid arthritis: an echocardiographic study].

1994

We used echocardiography to determine the prevalence of pericardial effusion in rheumatoid arthritis (RA) patients without cardiac systems and compared our results to those obtained in a control group of age-matched subjects. Thirty-six patients with RA (6 men, 30 women; mean age 51 +/- 11 years) were selected from a patient population in treatment at our outpatient Rheumatology Clinic. None of the patients had any symptoms of cardiac disease, and all patients with signs and/or systems of extracardiac disease were excluded from the study. The control group consisted of 60 volunteers (mean age 51 +/- 12 years) randomly selected from a larger group of subjects with neither symptoms, signs and…

Nonlinear coupling is absent in acute myocardial patients but not healthy subjects.

2008

We investigated whether autonomic nervous system imbalance imposed by pharmacological blockades and associated with acute myocardial infarction (AMI) is manifested as modifications of the nonlinear interactions in heart rate variability signal using a statistically based bispectrum method. The statistically based bispectrum method is an ideal approach for identifying nonlinear couplings in a system and overcomes the previous limitation of determining in an ad hoc way the presence of such interactions. Using the improved bispectrum method, we found significant nonlinear interactions in healthy young subjects, which were abolished by the administration of atropine but were still present afte…

Comparison of glycemic response and insulin requirements after mixed meals of equal carbohydrate content in healthy, type-1, and type-2 diabetic man

1989

The postprandial insulin requirements after three mixed meals of equal carbohydrate and energy content were assessed in 10 type-1 and 12 type-2 diabetics by a glucose-controlled insulin infusion system. These were compared with the glycemic response to the same meals of 10 healthy individuals (glycemic index). In type-1 diabetics, we found the highest insulin requirements after consumption of a continental breakfast (low fibre, low protein, high fat). Ten percent less insulin was infused after milk (low fat, high protein) and 30% less after an English breakfast (high fibre, high protein). Type-2 diabetics showed no significant differences in insulin requirements between the three test meals…

Effect of neuromuscular electrical stimulation frequency on postprandial glycemia, current-related discomfort, and muscle soreness. A crossover study

2019

Consensus is lacking regarding optimal neuromuscular electrical stimulation (NMES) parameters for postprandial glycemic control. Therefore, the aim of this study was to determine the NMES frequency inducing the greatest hypoglycemic effect in healthy individuals. The secondary aim was to compare current-related discomfort and muscle soreness between different frequencies. We conducted an experimental clinical study with a randomized crossover design. Sixteen healthy and sedentary participants received NMES for 20 min at 5, 10, or 50 Hz (pulse duration: 400 μs, on-off ratio: 4:12 s) following a standardized meal. Glycemia, discomfort, and muscle soreness during and after NMES were compared …
