Interaction of cerebrovascular disease and contralateral carotid occlusion in prediction of shunt insertion during carotid endarterectomy

2012

INTRODUCTION To assess the possible role and the interaction of cerebrovascular disease and vascular stenosis on the necessity of shunt insertion during carotid endarterectomy (CEA). MATERIAL AND METHODS Eighty consecutive patients undergoing CEA under regional anaesthesia were prospectively enrolled. Patients were divided into two groups depending on whether they were shunted or not. The measured end-points were co-morbidities degree of contralateral and carotid stenosis and other intra- and postoperative outstanding parameters. ANOVA, Student's t and χ(2) tests were used (p<0.05). Variables differing significantly between groups and potential confounders were used in backward stepwise log…

The cardinal exercise stopper: Muscle fatigue, muscle pain or perception of effort?

2018

The capacity to sustain high-intensity aerobic exercise is essential for endurance performance. Therefore, it is important to understand what is the factor limiting time to exhaustion (TTE) in healthy and fit adults. In Study 1, maximal voluntary cycling power (MVCP) was measured in 11 volunteers before and immediately after a high-intensity TTE test on cycle ergometer. Cadence was 60 rpm in both the MVCP and TTE tests. Despite a 35% loss in MVCP, power produced during the final MVCP test (mean ± SD 469 ± 111 W) was significantly higher than the power required by the TTE test (269 ± 55 W) (P < 0.001). In Study 2, 12 participants performed a cold pressor test (CPT) to the limit of tolerance …

Traditional vs daily undulling periodization in strength and local muscle endurance gains on trained men

2018

The aim of this study was to investigate the impact of different periodization models on strength and local muscle endurance. Twenty trained men (25.45 ± 2.984 years, 75.34 ± 6.05 kg, 177.25 ± 4.92 cm, 23.96 ± 1.64 kg . m-2) were randomly assigned in two groups: undulling periodization (UPG) and traditional periodization group (TPG), respectively. All the subjects performed one repetition maximum (1-RM) strength test and a local muscle endurance test (60% of 1-RM to failure) before, during and after experimental period. The UPG executed 30 workout sessions with daily modifications regarding intensity, volume and rest period length. The TGP was divided into 3 phases (10 workout sessions in e…

A PRISMA-compliant systematic review of the endpoints employed to evaluate symptomatic treatments for primary headaches

2018

Abstract Background Primary headache are prevalent and debilitating disorders. Acute pain cessation is one of the key points in their treatment. Many drugs have been studied but the design of the trials is not usually homogeneous. Efficacy of the trial is determined depending on the selected primary endpoint and usually other different outcomes are measured. We aim to critically appraise which were the employed outcomes through a systematic review. Methods We conducted a systematic review of literature focusing on studies on primary headache evaluating acute relief of pain, following the PRISMA guideline. The study population included patients participating in a controlled study about sympt…

Inspiratory Muscle Training and Functional Electrical Stimulation for Treatment of Heart Failure With Preserved Ejection Fraction: Rationale and Stud…

2016

Heart failure with preserved ejection fraction (HFpEF) has become the most prevalent form of heart failure in developed countries. Regrettably, there is no evidence-based effective therapy for HFpEF. We seek to evaluate whether inspiratory muscle training, functional electrical stimulation, or a combination of both can improve exercise capacity as well as left ventricular diastolic function, biomarker profile, quality of life (QoL), and prognosis in patients with HFpEF. A total of 60 stable symptomatic patients with HFpEF (New York Heart Association class II-III/IV) will be randomized (1:1:1:1) to receive a 12-week program of inspiratory muscle training, functional electrical stimulation, a…

Differential blockade by nifedipine and ω-conotoxin GVIA of α1- and β1-adrenoceptor-controlled calcium channels on motor nerve terminals of the rat

1990

Electrically evoked release of [3H]acetylcholine ([3H]ACh) from the rat phrenic nerve and its facilitation by stimulation of presynaptic alpha 1- and beta 1-adrenoceptors were investigated in the absence and presence of nifedipine and omega-conotoxin GVIA. Both calcium channel antagonists did not modify electrically evoked [3H]ACh release, but selectively blocked the effect triggered by both facilitatory adrenergic receptors. The increase in [3H]ACh release mediated via beta 1-adrenoceptor activation was abolished by low concentrations (1 nM) of omega-conotoxin GVIA, whereas nifedipine (100 nM) abolished the facilitatory effect mediated via alpha 1-adrenoceptor stimulation. Therefore, the b…

The conditioning of the trunk muscles and back health in Physical Education

2021

Background. The search for scientific arguments for the inclusion of back health as a fundamental aspect in the contents of physical conditioning for health in Physical Education (PE) in schools has led us to search for the relationship between the resistance of trunk musculature and non-specific low back pain in 1st year compulsory secondary education (CSE) students. Methods. Three tests were used: the front bridge (FB) test, the dominant side bridge (SB) test, and the modified Biering-Sorensen test (BS). The Nordic questionnaire was used to assess back health.Results. The prevalence of low back pain in boys was 58.3% (n = 42), while in girls it was 52.7% (n = 39) with no statistically sig…

Inclusión de la inyección percutánea de etanol como primera línea de tratamiento de los quistes tiroideos sintomáticos

2021

Abstract Background Our aim was to evaluate the efficacy and security of ultrasound-guided percutaneous ethanol injection therapy (US-PEIT) for the treatment of recurrent symptomatic thyroid cysts in two high-resolution consultations of thyroid nodule in the Valencian Community. Patients and methods The study comprised thirty-three consecutive patients (51 ± 12 years, 76% women) with symptomatic benign thyroid cysts relapsed after drainage and benign cytology prior to treatment. Through ultrasound, maximum cyst diameter and volume were determined, and the content of the cyst was drained. We then instilled between 2 and 4 ml of ethanol (according to initial volume). We followed up with ultra…

2017

Summary This systematic review summarizes the effect of\ud combined exercise and nutrition intervention on muscle mass\ud and muscle function. A total of 37 RCTs were identified.\ud Results indicate that physical exercise has a positive impact\ud on muscle mass and muscle function in subjects aged 65 years\ud and older.
