BACKGROUND: Pupillometry has shown promising results for assessing nociception in anesthetized patients. However, its benefits in clinical practice are not demonstrated. The aim of this prospective randomized study was to evaluate the impact of intraoperative pupillometry monitoring on perioperative opioid consumption in major gynecologic surgery. METHODS: After receiving ethics committee approval and written consent of patients, American Society of Anesthesiologists status I to II women undergoing gynecologic surgery were included in this single-blinded, prospective, parallel-arm randomized study...

BACKGROUND: Signs of hypovolaemia are frequent in the postoperative period, but not all patients need or respond to fluid administration. An increase in cardiac output (CO) after passive leg raising (PLR) has been demonstrated to be useful as a volume response predictor in non-surgical, spontaneously breathing patients. OBJECTIVE: The objective of this study was to evaluate the accuracy of transthoracic echocardiography after PLR to predict fluid responsiveness in post-surgical patients...

: The anaesthetic management of patients with myopathies is challenging. Considering the low incidence and heterogeneity of these disorders, most anaesthetists are unfamiliar with key symptoms, associated co-morbidities and implications for anaesthesia. The pre-anaesthetic assessment aims at the detection of potentially undiagnosed myopathic patients and, in case of known or suspected muscular disease, on the quantification of disease progression. Ancillary testing (e.g. echocardiography, ECG, lung function testing etc...

Amitraz is an acaricide and insecticide used to treat ticks, which infest domestic animals in developing countries. Because of its widespread use, it is one of the common poisons unintentionally consumed by infants and children when left unsupervised. A 3-year-old boy was brought with unintentional consumption of Amitraz. On examination, he was found to be progressively drowsy, with an irregular pulse, bradycardia, and hypotension. He was treated with atropine, intravenous fluids, and dopamine infusion; hemodynamic stability was achieved within 36 hours after ingestion...

Pain is the most feared symptom amongst individuals living with cancer. In 15% to 20% of patients, conventional analgesic therapy either fails to relieve pain or induces adverse effects. Intrathecal drug delivery systems may present an effective alternative for pain management. The Cancerology Center Paul Papin protocol includes an admixture of morphine, ropivacaine, and ziconotide in intrathecal preparations. These drugs are administered by a fully implantable or an external pump. Syringes or polyolefin infusion bags are prepared for refill just before use...

The position of double bonds along the carbon chain of methylene interrupted polyunsaturated fatty acids are unique identifiers of specific fatty acids derived from biochemical reactions that occur in cells. It is possible to obtain direct structural information as to these double bond positions using tandem mass spectrometry after collisional activation of the carboxylate anions of an acetone adduct at each of the double bond positions formed by the photochemical Paternò-Büchi reaction with acetone. This reaction can be carried out by exposing a small portion of an inline fused silica capillary to UV photons from a mercury vapor lamp as the sample is infused into the electrospray ion source of a mass spectrometer...

BACKGROUND: The deposit of Advanced Glycation End-products (AGEs) is involved in diabetic complications. It can be evaluated by measuring the skin autofluorescence (sAF). We searched whether sAF progressed over 4 years in Type 1 Diabetes, and analysed its relationship with the development of nephropathy. METHODS: Two measurements of sAF was realized on 154 patients during years 2009 and 2013. Baseline factors associated to the progression of sAF were analyzed by multivariate regression analysis...

AIM: Brain inflammation is associated with several brain diseases such as multiple sclerosis (MS), a disease characterized by demyelination. Whether prenatal immune challenge affects demyelination-induced inflammation in the white matter during adulthood is unclear. In the present study, we used a well-established experimental model of focal demyelination to assess whether prenatal immune challenge affects demyelination-induced inflammation. METHODS: Pregnant rats were injected with either lipopolysaccharide (100 μg/kg, ip) or pyrogen-free saline...

Sprague Dawley rats were subjected to acute myocardial infarction (AMI) by permanent ligation of the left anterior descending coronary artery. At the time of AMI, a subcutaneous mini-osmotic pump was implanted and animals were randomized into three groups, according to the intravenous therapy received during the first 72 h: placebo-treated (saline), serelaxin10-treated (SRLX10 = 10 μg/kg/day), or serelaxin30-treated (SRLX30 = 30 μg/kg/day). Treatment with SRLX30 reduced the expression of inflammatory cytokines and chemokines, as well as the infiltration of macrophages, and increased the expression of pro-angiogenic markers and vessel density in the infarcted myocardium after 7 days...

Once incision and drainage of fascial space abscess is performed, irrigation of deep spaces with saline and antibiotic solution should be done daily for effective elimination or reduction of infection. Various advocated aids for irrigation into deeper areas are: small pediatric nasogastric feeding tubes, French catheter, polyethylene irrigation tubes and scalp vein infusion set. All these aids have major inherent disadvantages like, they tend to kink inside the deep spaces limiting the reach of irrigating solution into deeper spaces, are not readily available in dental departments and have to be discarded after every use...

In recent years shape-memory polymers have been under intense investigation due to their unique mechanical, thermal, and electrical properties that could potentially make them extremely valuable in numerous engineering applications. In this manuscript, we report a polymer-template-assisted assembly manufacturing strategy used to fabricate graphite/silver nanowires/epoxy resin (PGSE) composite. In the proposed method, the porous polymer foams work as the skeleton by forming three-dimensional graphite structure, whereas the silver nanowires act as the continuous conductive network...

This retrospective cohort study included 53 patients admitted in ICU, of average age 69 years, without neurologic disorder before initiation of piperacillin continuous infusion at standard dose and who underwent piperacillin serum concentration monitoring. Among them, 23 developed neurologic disorder for which the piperacillin causality was chronologically and semiologically suggestive. A concentration threshold of 157.2 mg/L independently predicted neurotoxicity with 96.7% specificity and 52.2% sensitivity and may constitute a limitation when targeting less susceptible pathogens...

The transcription factor nuclear factor of activated T-cells 1 (NFAT1), with the aid of transcriptional coactivators, has been recognized for its necessity and sufficiency to drive pathological cardiac hypertrophy. However, how the transcriptional activity of NFAT1 in terms of cardiac hypertrophy is controlled at the transcriptional level has not been well defined. Herein, we showed that a cardiac-enriched protein IRF2BP2 (interferon regulatory factor-2 binding protein 2) was further upregulated in both human and mouse hypertrophied myocardium and negatively regulated cardiomyocyte hypertrophic response in vitro...

HIV-associated neurocognitive disorder (HAND) affects approximately half of HIV-infected patients. Loss of synaptic connections is a hallmark of many neurocognitive disorders, including HAND. The HIV-1 protein transactivator of transcription (Tat) disrupts synaptic connections both in vitro and in vivo and has been linked to impaired neurocognitive function in humans. In vitro studies have shown that ifenprodil, an antagonist selective for GluN2B-containing NMDARs, reverses synapse loss when applied after Tat...

The context preexposure facilitation effect (CPFE) is a contextual fear conditioning paradigm in which learning about the context, acquiring the context-shock association, and retrieving/expressing contextual fear are temporally dissociated into three distinct phases. In contrast, learning about the context and the context-shock association happens concurrently in standard contextual fear conditioning (sCFC). By infusing the GABAA receptor agonist muscimol into medial prefrontal cortex (mPFC) in adolescent Long-Evans rats, the current set of experiments examined the functional role of the mPFC in each phase of the CPFE and sCFC...

Infliximab (IFX) is a chimeric mAb that can lead to the appearance of anti-drug Abs. Recent research has identified the presence of circulating IFX-specific T cells in treated patients. The aim of the study was to analyze the functional characteristics of IFX-specific T cells, in particular their capability to produce biologically active regulatory cytokines. Drug-stimulated PBMCs or coculture systems were used to detect memory T cells in treated patients. The cytokines produced by IFX-specific T cells, T cell lines, and T cell clones were evaluated at the mRNA and protein levels...

Store-operated Ca(2+) release-activated Ca(2+) (CRAC) channels are involved in the pathogenesis of rheumatoid arthritis (RA) and have been studied as therapeutic targets in the management of RA. We investigated the efficacy and safety of CRAC inhibitors, including a neutralizing Ab (hCRACM1-IgG) and YM-58483, in the treatment of RA. Patient-derived T cell and B cell activity was suppressed by hCRACM1-IgG as well as YM-58483. Systemically constant, s.c. infused CRAC inhibitors showed anti-inflammatory activity in a human-NOD/SCID xenograft RA model as well as protective effects against the destruction of cartilage and bone...
