Abstract (sommario):

Increasing litter size may lead to low-birth-weight piglets (LBW) and further negative long-term effects. This study aimed to evaluate the effects of intramuscular administration (IM) of dexamethasone (Dexa) alone or in combination with vitamin E/Se on LBW piglets during the early postnatal period. The study included a total of 100 LBW piglets that were divided into 5 groups (20 LBW piglets per group) and treated with IM Dexa alone or in combination with vitamin E/Se (Vit E/Se) after birth as follows: (a) Group A-Cont: Control group, (b) Group B-Dexa1: Dexa on D1 (1st day of life), (c) Group C

Abstract (sommario):

Muscle atrophy, a physiological decline in muscle mass and strength due in ageing, occurs through an imbalance between protein breakdown and synthesis. The purpose of this study was to verify whether amino acid complex supplementation (ACS) can prevent and treat muscle loss in a dexamethasone (Dexa, 800 μg/kg)-induced rat model of sarcopenia. Sprague Dawley rats (6 weeks old) were assigned to seven groups: (i) normal control, (ii) positive control (high-dose ACS, 500 mg), (iii) Dexa only, (iv) Dexa + high-dose ACS (500 mg), (v) Dexa + medium-dose ACS (300 mg), (vi) Dexa + low-dose ACS (100 mg)

Abstract (sommario):

It is well known that oxidative stress induces muscle atrophy, which decreases with the activation of Nrf2/HO-1. Fermented oyster extracts (FO), rich in γ-aminobutyric acid (GABA) and lactate, have shown antioxidative effects. We evaluated whether FO decreased oxidative stress by upregulating Nrf2/HO-1 and whether it decreased NF-κB, leading to decreased IL-6 and TNF-α. Decreased oxidative stress led to the downregulation of Cbl-b ubiquitin ligase, which increased IGF-1 and decreased FoxO3, atrogin1, and Murf1, and eventually decreased muscle atrophy in dexamethasone (Dexa)-induced muscle atro

Abstract (sommario):

Rebound pain (RP) remains a challenge in ambulatory surgery, characterized by severe pain upon resolution of a peripheral nerve block (PNB). Intravenous (IV) administration of Dexamethasone (DEXA) potentiates PNB analgesic effect and reduces RP incidence although preventive effective dose remains undetermined. This retrospective analysis evaluates the preventive effect of IV DEXA on RP in outpatients undergoing upper limb surgery under axillary block. DEXA was divided into high (HD > 0.1 mg/kg) or low (LD < 0.1 mg/kg) doses. RP was defined as severe pain (NRS ≥ 7/10) within 24 h of PNB r

Abstract (sommario):

Dexamethasone (Dexa), frequently used as an anti-inflammatory agent, paradoxically leads to muscle inflammation and muscle atrophy. Receptor for advanced glycation end products (RAGE) and Toll-like receptor 4 (TLR4) lead to nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3 (NLRP3) inflammasome formation through nuclear factor-κB (NF-κB) upregulation. NLRP3 inflammasome results in pyroptosis and is associated with the Murf-1 and atrogin-1 upregulation involved in protein degradation and muscle atrophy.

Abstract Background Osteoporosis is compromised bone strength that predisposes to fracture. It can be diagnosed by Dual-energy x-ray absorptiometry (DEXA) measurement of bone mineral density (BMD). Persons with HIV (PWH) are at higher risk for the development of osteoporosis. As such, the HIV Medicine Association’s (HIVMA) primary care guidelines recommend DEXA screening for all HIV-infected postmenopausal women and men aged ≥50 years. The purpose of this study was to asses the frequency of DEXA utilization within a tertiary-care urban academic center in the Midwest and to identify prevalence

Because fat and lean tissues each contain various components, these inaccuracies likely result from selection of inappropriate calibration standards.

Increased level of drug in the cerebrospinal fluid might also prevent meningeal leukemic infiltration. However, high dose of Dexa may be associated with an increased risk of sepsis and fungal infections. By using a lower dose of dexamethasone these serious infections may be circumvented without jeopardize the antileukemic activity. The main aim of the EORTC ALL-4 study was to determine the efficacy

Abstract (sommario):

Aging and chronic disease are often accompanied by changes in body composition that lead to decreased muscle mass and increased fat mass, even in weight-stable individuals. Both obesity and sarcopenia are important causes of frailty, disability, morbidity, and mortality. Diminished skeletal muscle and expanded visceral fat can act synergistically, which might maximize their effects on physical impairments and metabolic disorders. Dual-energy X-ray absorptiometry (DEXA) was regarded as one of the most versatile imaging techniques for evaluation of sarcopenia and obesity as well as osteoporosis.

Abstract (sommario):

Four methods for predicting body composition were compared in premenopausal females (n = 100), 28#x2013;39 yr old, by using underwater weighing (UWW) as the criterion method. The four methods were dual energy X-ray absorptiometry (DEXA), skinfolds, bioelectrical impedance, and body mass index. The sample had a mean percent fat (%fat) of 29.7 +/- 6.8% (SD) by DEXA and 29.9 +/- 5.8% measured by UWW. DEXA yielded a standard error of estimate (SE) of 2.4% (r = 0.91) for the prediction of %fat from UWW. When %fat was estimated from other methods, larger SEs were obtained: 3.0% for skin-folds, 3.3%
