BACKGROUND: Shivering is a common postanesthesia adverse event with multiple etiologies. At present tramadol is a widely used drug for the control of shivering. However, tramadol may cause a lot of nausea and vomiting. Hence, the need to find a better drug with less of side effects. The aim of this study was to compare the efficacy of dexmedetomidine and tramadol in the treatment of post-spinal anesthesia (SA) shivering as well as to compare their side-effect profile. MATERIALS AND METHODS: This prospective, double-blind, randomized controlled trial was conducted in a tertiary care hospital...

This study compared perianesthetic body temperatures and times to recovery from general anesthesia in small dogs that were either warmed for 20 minutes prior to anesthesia or not warmed. Twenty-eight client-owned dogs that were presented for ovariohysterectomy were included in the study. Small (<10 kg body weight) dogs with normal circulatory status were randomly assigned to receive pre-warming for 20 minutes or no treatment. Body temperature was measured during the procedure using a calibrated rectal probe...

A 38-year-old African American male patient with a past medical history of human immunodeficiency virus and schizophrenia who was noncompliant with medications presented to the emergency department (ED) after activation of the local crisis response center for altered mental status. Upon arrival he was lethargic and uncooperative, unable to provide any significant details apart from pleuritic chest pain. His blood pressure was 133/88 mmHg, heart rate 43 beats per minute and initial body temperature 36.1 °C which prompted an electrocardiogram (EKG)...

BACKGROUND: Propofol injection pain (PIP) has been adequately studied during the past decades. However, patients' opinion on this problem and the incidence of patients' recall of this brief discomfort are still unknown. Thus, we conducted this study to know the patients' perspectives on PIP and provide useful information about the incidence of recall of PIP under our routine general anesthesia. METHODS: Five hundred preoperative questionnaires were distributed to patients who were scheduled for elective open thyroidectomy under general anesthesia from May 2016 to July 2016...

Natural products harbor unique and complex structures that provide valuable antibiotic scaffolds. With an increase in antibiotic resistance, natural products once again hold promise for new antimicrobial therapies, especially those with unique scaffolds that have been overlooked due to a lack of understanding of how they function. Dithiolopyrrolones (DTPs) are an underexplored class of disulfide-containing natural products, which exhibit potent antimicrobial activities against multidrug-resistant pathogens...

Brown adipose tissue (BAT) is responsible for thermogenesis that is not associated with shivering through the process of converting chemical energy into heat through uncoupling protein 1 (UCP1) in the mitochondria. Thus, expanding or activating BAT could be a potential tool against obesity. To analyze the effect of kinase signaling on brown adipocyte formation, a process that describes the acquisition of the ability to dissipate energy as heat, we performed lentiviral-mediated short hairpin knockdown or used pharmacological inhibitors in a high-content and high-throughput in vitro image-based screen...

The application of targeted temperature management has become common practice in the neurocritical care setting. It is important to recognize the pathophysiologic mechanisms by which temperature control impacts acute neurologic injury, as well as the clinical limitations to its application. Nonetheless, when utilizing temperature modulation, an organized approach is required in order to avoid complications and minimize side-effects. The most common clinically relevant complications are related to the impact of cooling on hemodynamics and electrolytes...

The therapeutic effect of glial progenitor transplantation in diseases of dysmyelination is currently attributed to the formation of new myelin. Using magnetic resonance imaging (MRI), we show that the therapeutic outcome in dysmyelinated shiverer mice is dependent on the extent of cell migration but not the presence of mature and compact myelin. Human or mouse glial restricted progenitors (GRPs) were transplanted into rag2(-/)(-) shiverer mouse neonates and followed for over one year. Mouse GRPs produced mature myelin as detected with multi-parametric MRI, but showed limited migration without extended animal lifespan...

Shivering associated with spinal anesthesia during Cesarean delivery is an uncomfortable experience for the parturient, which may also cause adverse effects. In this prospective, randomized, double-blind, placebo-controlled study, we sought to evaluate the effect of intrathecal dexmedetomidine, administered as an adjunct to hyperbaric bupivacaine for Cesarean delivery, on the incidence and severity of shivering associated with spinal anesthesia. Patients undergoing Cesarean delivery were randomly allocated to three groups of 30 patients each...

INTRODUCTION: Croatia is endemic for hemorrhagic fever with renal syndrome (HFRS), with both Puumala (PUUV) and Dobrava virus (DOBV) documented. Several large outbreaks were recorded in 1995, 2002, and 2012. We analyzed demographic, clinical, laboratory, and virological characteristics of HFRS cases detected in three geographically close natural foci (Ogulin, Slunj, and the Plitvice Lakes surroundings) during the 2014 outbreak. METHODOLOGY: From January to December 2014, 122 patients with suspected HFRS were tested for hantavirus IgM/IgG antibodies using an indirect immunofluorescence assay (IFA)...

Uncoupling protein 2 (UCP2) was discovered in 1997 and classified as an uncoupling protein largely based on its homology of sequence with UCP1. Since its discovery, the uncoupling function of UCP2 has been questioned and there is yet no consensus on the true function of this protein. UCP2 was first proposed to be a reactive oxygen species (ROS) regulator and an insulin secretion modulator. More recently, it was demonstrated as a regulator of the mitochondrial fatty acid oxidation, which prompted us to investigate its role in the metabolic and thermogenic functions of brown adipose tissue...

BACKGROUNDS: Remifentanil has been reported to cause post-anesthetic shivering (PAS). Higher doses of remifentanil reportedly induce more intense PAS. Tramadol, a synthetic opioid that acts at multiple sites, is considered to be an effective treatment for PAS, but the evidence for its therapeutic benefit after remifentanil anesthesia is limited. We investigated the effect of tramadol on the incidence of PAS after remifentanil anesthesia. METHODS: Sixty-three patients who had undergone upper abdominal surgery under general anesthesia were studied retrospectively...

Active brown adipose tissue is responsible for non-shivering thermogenesis in mammals which affects energy homeostasis. The molecular mechanisms underlying this activation as well as the formation and activation of brite adipocytes have gained increasing interest in recent years as they might be utilized to regulate systemic metabolism. We show here that the transcriptional regulators SRF and MKL1 both act as repressors of brown adipogenesis. Loss-of-function of these transcription factors leads to a significant induction of brown adipocyte differentiation, increased levels of UCP1 and other thermogenic genes as well as increased respiratory function, while SRF induction exerts the opposite effects...

Brown adipose tissue (BAT) provides a means of non-shivering thermogenesis. In humans, active BAT can be visualized by (18)F-fluoro-desoxyglucose (FDG) uptake as detected by positron emission tomography (PET) combined with computer tomography (CT). The retrospective analysis of clinical scans is a valuable source to identify anthropometric parameters that influence BAT mass and activity and thus the potential efficacy of envisioned drugs targeting this tissue to treat metabolic disease. We analyzed 2854 FDG-PET/CT scans from 1644 patients and identified 98 scans from 81 patients with active BAT...

Cardiovascular and metabolic disturbances individually and interdependently lead to chronic pathological conditions observed in cardio-metabolic diseases (CMDs). In Europe, the morbidity and mortality caused by cardiovascular disease are the highest among all diseases. Therefore, it seems important to search for new and alternative therapies for obesity, which is the main cause of type 2 diabetes (T2D) and cardiovascular disease (CD). Great attention has been paid to the role of brown adipose tissue in fat burning and the possibility of transformation of the white adipose tissue to cells with brown adipose tissue function as a potential form of treatment of obesity...

Siblings of brothers or sisters with intellectual and developmental disabilities (IDD) are important but understudied family members. As many previous studies have relied on parent report of sibling outcomes, the use of sibling self-report is an important addition to the research. This study assessed the feelings of adolescent siblings toward their brothers or sisters with and without IDD, as well as broader aspects of sibling empathy. Data were collected via a national, online survey from 97 parent-sibling pairs...

Indirect evidence from human studies suggests that brown adipose tissue (BAT) thermogenesis is fueled predominantly by fatty acids hydrolyzed from intracellular triglycerides (TGs). However, no direct experimental evidence to support this assumption currently exists in humans. The aim of this study was to determine the role of intracellular TG in BAT thermogenesis, in cold-exposed men. Using positron emission tomography with (11)C-acetate and (18)F-fluorodeoxyglucose, we showed that oral nicotinic acid (NiAc) administration, an inhibitor of intracellular TG lipolysis, suppressed the cold-induced increase in BAT oxidative metabolism and glucose uptake, despite no difference in BAT blood flow...
