Effects of Resistance Training of Peripheral Muscles Versus Respiratory Muscles in Older Adults With Sarcopenia Who are Institutionalized: A Randomiz…
2018
[EN] This study compares the effects of two resistance training programs in peripheral and respiratory musculature on muscle mass and strength and physical performance and identifies the appropriate muscle mass parameter for assessing the intervention effects. Thirty-seven institutionalized older Spanish adults with sarcopenia were analyzed: control group (n = 17), respiratory muscle training group (n = 9), and peripheral muscle training group (n = 11). Measured outcomes were appendicular skeletal muscle mass (ASM/height(2), ASM/weight, and ASM/BMI), isometric knee extension, arm flexion and handgrip strength, maximal inspiratory and expiratory pressures, and gait speed pre- and postinterve…
Feasible Evaluation of PQ Bypass Results with Duplex Ultrasound
2019
Abstract Patients with peripheral arterial disease (PAD) have substantially impaired health-related quality of life (HR-QoL). Chronic lower limb ischaemia due to the atherosclerotic occlusion of infra-inguinal arteries is one of the most important causes of invalidity among smokers over the age of fifty. Historically, these lesions were treated by open bypass surgery. Less invasive endovascular revascularisation methods are available to treat short lesions, while treatment of long lesions are lacking. Fully endovascular trans-venous femoro-popliteal bypass (PQ Bypass, Inc., Sunnyvale, CA, USA) to treat long femoral lesions has been developed recently. The objective of the study was to evalu…
Muscarine receptors on the rat phrenic nerve, evidence for positive and negative muscarinic feedback mechanisms.
1987
Neuronal transmitter stores of the rat phrenic nerve were labelled by incubation with [3H]choline. Release of [3H]acetylcholine was elicited by electrical nerve stimulation (100 or 1500 pulses, 5 or 25 Hz) or by high potassium (27 mmol/l) and the effects of the muscarine receptor agonist oxotremorine and the antagonist scopolamine were investigated. Neither oxotremorine nor scopolamine affected the basal tritium efflux. A low concentration of oxotremorine (10 nmol/l) enhanced and a high concentration of oxotremorine (1 μol/l) reduced the electrically evoked [3H]acetylcholine release. Likewise, the high potassium-evoked [3H]acetylcholine release was reduced by a high concentration of oxotrem…
Insights on Central and Peripheral Venous Catheterization; Biology, Anatomy, Surgical Aspects and Nursing Management (Our Experience)
2009
After a review of the main anatomical districts of relevance to central and peripheral venous catheterization, we analyze the primary guidelines for the management of cannulation of central and peripheral venous catheters; a background study relative to this subject is then carried out. The aim of the present study is to review the main central and peripheral catheterization methods, and to share our experience with particular emphasis on analyzing common complications
BDNF is essentially required for the early postnatal survival of nociceptors
2010
AbstractNeurotrophins promote the survival of specific types of neurons during development and ensure proper maintenance and function of mature responsive neurons. Significant effects of BDNF (Brain-Derived Neurotrophic Factor) on pain physiology have been reported but the contribution of this neurotrophin to the development of nociceptors has not been investigated. We present evidence that BDNF is required for the survival of a significant fraction of peptidergic and non-peptidergic nociceptors in dorsal root ganglia (DRG) postnatally. Bdnf homozygous mutant mice lose approximately half of all nociceptive neurons during the first 2 weeks of life and adult heterozygotes exhibit hypoalgesia …
Meningiomas of the Space of the Cavernous Sinus
1996
During the years 1985 to 1992, we encountered 59 patients with meningiomas involving the space of the cavernous sinus. In 29 of these patients, meningiomas were primarily located within the space of the cavernous sinus and were operated on without mortality and with low morbidity. A small subtemporal surgical approach was favored, which allowed initial tumor resection from the posterior aspect, where the Parkinson's triangle is wide, thus avoiding the additional morbidity of large-scale approaches. According to the relationships of the all-important cranial nerves passing within the lateral wall of the cavernous sinus, we divided the primary intracavernous meningiomas into four types, which…
Use of statins in patients with peripheral artery disease
2018
Atherosclerotic peripheral artery disease (PAD) is a growing health issue that affects more than 200 million individuals worldwide, conferring a high risk of cardiovascular events and death. In spite of its high prevalence, PAD has often been neglected in the past and the heightened cardiovascular risk of patients with PAD has been consistently under-recognized by practitioners. Considering that an integrated approach to reduce cardiovascular events and lower limb complications is necessary in this setting, statins represent the cornerstone of therapy as reported by current American and European guidelines. Literature has extensive data about the importance of lipid-lowering therapy in pati…
Impaired Fractional and Coronary Flow Reserve
2016
A FFR <0.80/0.75 witnesses the existence of a high-grade epicardial stenosis. In this setting, the CFR is usually also impaired since even a maximal dilation of the peripheral resistances cannot compensate for the increased epicardial resistances.
Klinische Erfahrungen mit dem Kensey-Katheter-System - Komplikationen und Ergebnisse
1990
Fifteen procedures have been carried out in 14 patients using the Kensey rotation angioplasty system. Sixteen occlusions of the superficial femoral artery, with an average length of 10.2 cm (3 to 24 cm) and one artery with multiple stenoses were treated. The following results were obtained: creation of a lumen, with subsequent balloon dilatation in eight out of fifteen procedures; in two patients the vessels were occluded shortly after the procedure, due to complications (one obstructive plaque and one haematoma); five perforations, three dissections and one peripheral embolus. The total complication rate was 11 out of 15 cases, clinical improvement was obtained in six out of 15 cases.
Modification of Angular Kinematics and Spatiotemporal Parameters during Running after Central and Peripheral Fatigue
2021
Fatigue causes kinematics modifications during running, and it could be related to injuries. The aim was to identify and compare the effects of central and peripheral fatigue on angular kinematics and spatiotemporal parameters during running. Angular kinematics and spatiotemporal parameters were evaluated using an infrared motion capture system and were registered during 2 min treadmill running in pre- and post-fatigue states in eighteen male recreational runners. Central fatigue was induced by a 30 min running fatigue protocol on a treadmill, while peripheral fatigue in quadriceps and hamstrings muscles was induced by an isokinetic dynamometer fatigue protocol. Central fatigue increased th…
