Nutrition and physical activity in the prevention and treatment of sarcopenia: systematic review

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. However, any interactive effect of dietary supplementation\ud appears to be limited.\ud Introduction In 2013, Denison et al. conducted a systematic\ud review including 17 randomized controlled trials\ud (RCTs) to explore the effect of combined exercise and\ud nutrition intervention to improve muscle mass, muscle\ud strength, or physical performance in older people.\ud They c…

Hypovitaminosis D and orthostatic hypotension: A systematic review and meta-analysis

2016

Objectives: Orthostatic hypotension is a common condition among older adults and is associated with a range of deleterious outcomes. Recently, interest has developed in hypovitaminosis D (defined as low 25 hydroxiyVitamin D levels) as a potential risk factor for orthostatic hypotension. We conducted a systematic review and meta-analysis examining the association of orthostatic hypotension between study participants with and without hypovitaminosis D, including the adjustment of potential confounders (age, sex, BMI, renal function, comorbidities, seasonality, use of antihypertensive medications, and supplementation with cholecalciferol). Methods: A systematic literature search of major elect…

Effect of 2 years of endurance and high-impact training on preventing osteoporosis in postmenopausal women: randomized clinical trial.

2018

The aim of the study was to analyze the effects of endurance and high-impact training oriented toward preventing osteoporosis in postmenopausal women with calcium and vitamin D supplementation.This study was a randomized clinical trial. Thirty-six postmenopausal women were randomized to the control and experimental groups. Thirty-four women completed the 2-year interventions. The control group training involved walking at an intense pace. The experimental group conducted high-impact training specifically oriented to prevent osteoporosis. Dual-energy x-ray absorptiometry was used to estimate the T-scores of the lumbar spine and femoral neck.The fast-walking group showed constant T-scores in …

Octaplex in routine clinical use for prophylaxis and therapy of bleeding in patients with prothrombin complex factor deficiency

2007

Octaplex is a new prothrombin complex concentrate that is indicated for treatment or perioperative prophylaxis of bleeding in patients with deficiency of the prothrombin complex coagulation factors, such as deficiency caused by treatment with vitamin K antagonists or by liver failure, when rapid correction of bleeding is required. The study was conducted to demonstrate both prevention of bleeding and achievement of haemostasis in acute bleeding and to obtain further information about the safety of administration of Octaplex.

Acetyl-L-Carnitine Supplementation and the Treatment of Depressive Symptoms: A Systematic Review and Meta-Analysis.

2017

Objective: Deficiency of acetyl-l-carnitine (ALC) seems to play a role in the risk of developing depression, indicating a dysregulation of fatty acid transport across the inner membrane of mitochondria. However, data about ALC supplementation in humans are limited. We thus conducted a systematic review and meta-analysis investigating the effect of ALC on depressive symptoms across randomized controlled trials (RCTs). Methods: A literature search in major databases, without language restriction, was undertaken from inception until 30 December 2016. Eligible studies were RCTs of ALC alone or in combination with antidepressant medications, with a control group taking placebo/no intervention or…

RELATIONSHIP BETWEEN VITAMIN D STATUS AND EARLY ARTERIAL CHANGES IN PRIMARY HYPERTENSION. PRELIMINARY DATA

2011

La nutrición en el periodo preconcepcional y los resultados del embarazo: revisión bibliográfica y propuesta de intervención del Dietista-Nutricionis…

2016

El estado nutricional de la madre antes y durante el embarazo se constata en los últimos años como uno de los factores ambientales más influyentes en el desarrollo fetal. Este estudio se centra en las primeras fases del proceso de gestación o periodo periconcepcional: preconcepción, concepción, implantación, placentación y embriogénesis; puesto que representan un paso crítico en los resultados del embarazo. Tras una revisión bibliográfica exhaustiva de 66 investigaciones publicadas entre los años 1990 y 2015, fueron el zinc, el hierro, el yodo, los ácidos grasos omega-3, el ácido fólico y otras vitaminas del grupo B, los minerales y micronutrientes para los que se han encontrado mayor evide…

Single Preoperative Oral Application of Ascorbic Acid Does Not Affect Postoperative Plasma Levels of Ascorbic Acid

2002

<i>Background and Aims:</i> A decrease in ascorbic acid (AA) plasma concentration is well known during the postoperative period and postulated to be caused by increased radical scavenging activity in response to surgical trauma. This often affects postoperative patients and is associated with multiple organ failure. Therefore, substitution of AA could potentially decrease the risk of postoperative complications. This study examines the effect of preoperative oral administration of 1,000 mg AA on the postoperative AA plasma concentration. <i>Methods:</i> 54 patients were randomly split into two groups; patients in group 1 received no AA preoperatively while group 2 re…

Retinoids induce MMP-9 expression through RARalpha during mammary gland remodeling.

2007

Retinoic acid (RA) is a signaling molecule in the morphogenesis of the mammary gland, modulating the expression of matrix metalloproteinases (MMPs). The aim of this paper was to study the role of RA during weaning, which consists of three events: apoptosis of the secretory cells, degradation of the extracellular matrix, and adipogenesis. CRABP II and CRBP-1 carrier proteins increased significantly during weaning compared with lactating glands but reverted to control values after the litter resuckled. The effects of RA are mediated by the nuclear receptors RARalpha, RARbeta, RARgamma, and RXRalpha, which underwent an increase in protein levels during weaning. In an attempt to elucidate the R…

Can Vitamin D deficiency influence muscle perfomance in post-menopausal women? A multicenter retrospective study

2018

Background: The presence of the vitamin D receptor (VDR) has been recently demonstrated in human muscle supporting the theory of a role of vitamin D in the proliferation and differentiation of muscle cells. So far only few studies investigated the association between vitamin D and muscle performance in postmenopausal women. Aim: To define the functional impact of vitamin D deficiency. Design: Multicenter retrospective study. Setting: Five Italian outpatient services of Physical and Rehabilitation Medicine (PRM). Population: Postmenopausal women. Methods: We divided the population in two groups based on the threshold of 30 ng/mL as cut-off to define sufficient and insufficient serum levels o…
