BACKGROUND: Anaesthesiologists are facing the problem of an increasing population of morbidly obese patients. In order to minimize the risk of opioid-induced postoperative respiratory failure, the intraoperative administration of opioids should be reduced or replaced with other drugs. The purpose of this study was to compare haemodynamic response elicited by intubation in morbidly obese patients between two variants of anaesthesia induction: fentanyl-based or low-opioid using dexmedetomidine...

The diagnosis of drug hypersensitivity reactions (DHR) is complex, with many potential pitfalls. Although the use of clinical history and skin testing can be valuable, drug provocation testing (DPT) remains the gold standard for many DHR. However, DPT carries some potential risk and should not be performed for severe reactions. There is therefore a general consensus on the need for in vitro tests to achieve safe and accurate diagnosis of DHR. A range of in vitro approaches can be applied depending on the type of reaction and the immunological mechanism involved, i...

Chemotherapies drugs and monoclonal antibodies are key components of the treatment of cancer patients and patients with chronic inflammatory conditions to provide increase in life expectancy and quality of life. Their increased use has lead to an increase in drugs hypersensitivity reactions (DHR) worldwide. DHR to those agents prevented their use and promoted the use of second line therapies to protect patients' hypersensitive reactions and anaphylaxis. Second line medications may not fully address the patients' medical condition and it is desirable to keep patients on first line therapy...

RATIONALE: Siglec-8 is a surface receptor predominantly expressed on human eosinophils where its ligation induces reactive oxygen species (ROS) formation and cell death. Since Siglec-8 has intracellular tyrosine-based motifs, we hypothesized that Src family kinases (SFKs) are involved in ROS formation and cell death induced by Siglec-8 engagement. METHODS: Human peripheral blood eosinophils were purified and incubated with anti-Siglec-8 monoclonal antibodies (mAb, agonist), IL-5, and SFK pharmacological inhibitors...

BACKGROUND: Population studies have shown an inverse association between high-density lipoprotein (HDL) cholesterol levels and risk of coronary heart disease (CHD). HDL has different functions, including the ability to protect biological molecules from oxidation. Our aim was to evaluate the performance of two fluorescence-based assays in assessing the antioxidative capacity of HDL. METHODS: We compared the antioxidative capacity of HDL with the phospholipid 2',7'-dichlorodihydrofluorescein (DCF) assay and the dihydrorhodamine 123 (DHR) assay in controls and in subjects at increased risk of CHD, including subjects with established CHD, and subjects with elevated plasma triglycerides (TG), serum amyloid A (SAA), or myeloperoxidase (MPO) levels...

Drug induced exfoliative dermatitis (ED) are a group of rare and severe drug hypersensitivity reactions (DHR) involving skin and usually occurring from days to several weeks after drug exposure. Erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are the main clinical presentations of drug induced ED. Overall, T cells are the central player of these immune-mediated drug reactions. Here we provide a systematic review on frequency, risk factors, pathogenesis, clinical features and management of patients with drug induced ED...

BACKGROUND: Training programs have implemented the 2011 ACGME duty hour regulations (DHR) using "workload compression" (WLC) strategies, attempting to fit similar clinical responsibilities into fewer working hours, or workload reduction (WLR) approaches, reducing the number of patient encounters per trainee. Many have expressed concern that these strategies could negatively impact patient care and learner outcomes. OBJECTIVE: This study evaluates the medical knowledge and clinical impact of a WLR intervention in a single institution...

UNLABELLED: Peroxynitrite is a highly reactive nitrogen species and when it is generated at high levels it causes nitrosative stress, an important cause of impaired sperm function. High levels of peroxynitrite have been shown to correlate with decreased semen quality in infertile men. Thiol groups in sperm are mainly found in enzymes, antioxidant molecules, and structural proteins in the axoneme. Peroxynitrite primarily reacts with thiol groups of cysteine-containing proteins. Although it is well known that peroxynitrite oxidizes sulfhydryl groups in sperm, the subcellular localization of this oxidation remains unknown...

The present study examined the effects of wearing a lower-body compression garment (CG) after endurance exercise on recovery of physiological function. 18 males were divided into 2 experiments, the downhill running (n=10, DHR) experiments and the level running (n=8, LR) experiments. Subjects performed 30 min of DHR (gradient: - 10%) or LR (gradient: 0%) at 70% of  ˙VO2max with either wearing a CG (CG trial) or normal garment (CON trial) for 24 h after running. Changes in jump performance (counter movement jump; CMJ, rebound jump; RJ, drop jump; DJ), subjective feelings, circumferences of leg, and blood variables (creatine kinase, myoglobin, interleukin-6, high-sensitivity C-reactive protein) were evaluated before exercise, immediately after exercise, 1, 3 and 24 h following exercise...

A cross-sectional study combining different serological and molecular techniques for the detection of Ehrlichia species in dogs and their ticks was carried out with data from all regions of Costa Rica. A seroprevalence of 32.1% (131/408), and infection with E. canis of 3.2% (13/407) was found, whereas 6.9% (9/130) of ticks attached to the dogs were PCR positive to E. canis. Higher prevalences were found outside the Greater Metropolitan Area (GMA). Risk factors associated with E. canis seropositivity were age, between 2 and 7 years (RR: 1...

BACKGROUND: Discharge heart rate (HR) following ST-elevation myocardial infarction (STEMI) is a predictor of adverse left ventricular remodelling (LVR). However, the prognostic relevance of HR values in the earlier phase after revascularization is unknown. We aimed to investigate resting HR assessed at different time points during hospital stay following STEMI for the prediction of LVR. METHODS: In this prospective observational study of 143 consecutive STEMI patients, HR was measured serially on admission (AHR), at day 1 (HRd1) and 2 (HRd2) following revascularization and finally at discharge (DHR)...

Diapause is a developmental strategy adopted by insects to survive in challenging environments such as the low temperatures of a winter. This unique process is regulated by diapause hormone (DH), which is a neuropeptide hormone that induces egg diapause in Bombyx mori and is involved in terminating pupal diapause in heliothis moths. An G protein-coupled receptor from the silkworm, B. mori, has been identified as a specific cell surface receptor for DH. However, the detailed information on the DH-DHR system and its mechanism(s) involved in the induction of embryonic diapause remains unknown...

PURPOSE: Compare capillary and venous blood in the analysis of concentration and function of leucocyte sub-populations. This study hypothesised that capillary samples may be used in a site-specific manner as an alternative source of blood samples for assays of leucocyte concentration and neutrophilic phagocytic function and reactive oxygen species (ROS) production, allowing acquisition of multiple samples to better monitor transient but significant post-exercise immune modulation. METHODS: Resting blood samples were simultaneously obtained from vein, finger and earlobe of healthy subjects (n = 10, age: 25...
