REVIEW
Oluwaseun Akeju, Emery N Brown
General anesthesia is a man-made neurophysiological state comprised of unconsciousness, amnesia, analgesia, and immobility along with maintenance of physiological stability. Growing evidence suggests that anesthetic-induced neural oscillations are a primary mechanism of anesthetic action. Each anesthetic drug class produces distinct oscillatory dynamics that can be related to the circuit mechanisms of drug action. Sleep is a naturally occurring state of decreased arousal that is essential for normal health...

Fexofenadine, a potent antagonist to human histamine 1 (H1) receptor, is a non-sedative third generation antihistamine that is widely used to treat various human allergic conditions such as allergic rhinitis, conjunctivitis and atopic dermatitis. Encouragingly, it's been successfully used to treat canine atopic dermatitis, this supports the notion that it might have a great potential for treating other canine allergic conditions and other mammal pets such as dog. Regrettably, while there is a myriad of studies conducted on the interactions of antihistamines with human H1 receptor, the similar studies on non-human pet H1 are considerably scarce...

Norihiko Kamioka, Ateet Patel, Michael A Burke, Adam Greenbaum, Vasilis Babaliaros
Impella (Abiomed, Danvers, MA) is an effective option for emergent treatment of critical refractory cardiogenic shock. However, in patients who have inadequate peripheral arterial access, Impella for left ventricular support sometimes requires surgical access, leading to disadvantages for emergent procedures or invasiveness for very sick patients. In addition, Impella for right ventricular support was recently reported to contribute to the management of severe biventricular dysfunction. In this report, we describe a case of refractory cardiogenic shock in a patient with inadequate vascular access who was treated with biventricular Impella via venous and caval-aortic access under conscious sedation...

BACKGROUND: Intranasal administration of benzodiazepines has shown superiority over rectal administration for terminating emergency epileptic seizures in human trials. No such clinical trials have been performed in dogs. OBJECTIVE: To evaluate the clinical efficacy of intranasal midazolam (IN-MDZ), via a mucosal atomization device, as a first-line management option for canine status epilepticus and compare it to rectal administration of diazepam (R-DZP) for controlling status epilepticus before intravenous access is available...

Xuan Li, Hao Dong, Yifeng Zhang, Guoxin Zhang
BACKGROUND: Carbon dioxide (CO2) insufflation is increasingly used for endoscopic submucosal dissection (ESD) owing to the faster absorption of CO2 as compared to that of air. Studies comparing CO2 insufflation and air insufflation have reported conflicting results. OBJECTIVES: This meta-analysis is aimed to assess the efficacy and safety of use of CO2 insufflation for ESD. METHODS: Clinical trials of CO2 insufflation versus air insufflation for ESD were searched in PubMed, Embase, the Cochrane Library and Chinese Biomedical Literature Database...

Problematic internet use (PIU) has been suggested as in need of further research with a view to being included as a disorder in future Diagnostic and Statistical Manual (DSM) of the American Psychiatric Association, but lack of knowledge about the impact of internet cessation on physiological function remains a major gap in knowledge and a barrier to PIU classification. One hundred and forty-four participants were assessed for physiological (blood pressure and heart rate) and psychological (mood and state anxiety) function before and after an internet session...

We present a case in which we electively used venovenous extracorporeal membrane oxygenation (VV-ECMO) to facilitate safe resection of a nearly obstructing airway tumor near the carina in a 37-year-old male. The patient was brought to the operating room and underwent bifemoral cannulation for VV-ECMO under light sedation while maintaining spontaneous ventilation. After VV-ECMO was initiated, general anesthesia was induced, and the tumor was resected via rigid bronchoscopy. After resection, the patient was intubated, weaned from ECMO, decannulated, awoken, extubated, and taken to the postanesthesia care unit for recovery...

Drug and metabolite (analytes) identification together with quantification is an important analytical tool in forensic and clinical toxicology. We report the development and validation of a definitive detection and quantification method (UPLC-MS-MS) for initial screening of 64 analytes in urine. The principle of the method is a quantitative extension of a recently reported threshold accurate calibration (TAC) technique which employs a rapid dual-specimen analysis i.e., with and without addition of a reference-analyte standard for normalization of matrix effects...

Psoriasis is a chronic, inflammatory scaling dermatosis. The marked visible appearance of the lesions have a negative impact on body image that leads to decreased self-esteem, hence seriously compromising the patient's quality of life. The clinical picture critically affects the social well-being of the patient since the disease is commonly misunderstood and feared by the social environment as being contagious. The patient feels stigmatized and this further intensifies their lack of self-confidence and self-esteem...

Conscious perception relies on interactions between spatially and functionally distinct modules of the brain at various spatiotemporal scales. These interactions are altered by anesthesia - an intervention that leads to fading consciousness. Relatively little is known about brain functional connectivity and its anesthetic modulation at a fine spatial scale. Here, we used functional imaging to examine propofol-induced changes in functional connectivity in brain networks defined at a fine-grained parcellation based on a combination of anatomical and functional features...

The role of capnography in esophagogastroduodenoscopy (EGD) is controversial. Simultaneous supplemental oxygen, position of patient, open mouth breathing pattern, and anatomy of the oral and nasal cavity can influence capnography accuracy. This study first measured capnographic data via the nasal or oral cavity during sedated EGD. Secondly, we investigated the influence of supplementary oxygen through the oral cavity on the capnographic reading. Patients with ASA class I or II status admitted for routine EGD exams were enrolled...

RATIONALE AND OBJECTIVES: COR659 [methyl2-(4-chlorophenylcarboxamido)-4-ethyl-5-methylthiophene-3-carboxylate] is a new, positive allosteric modulator (PAM) of the GABAB receptor. This study evaluated whether COR659 shared with previously tested GABAB PAMs the capacity to reduce alcohol self-administration in rats. RESULTS: Treatment with non-sedative doses of COR659 (2.5, 5, and 10 mg/kg; i.p.) suppressed lever-responding for alcohol (15% v/v) in Sardinian alcohol-preferring (sP) rats under the fixed ratio (FR) 4 (FR4) and progressive ratio (PR) schedules of reinforcement; COR659 was more potent and effective than the reference GABAB PAM, GS39783...

RATIONALE: Kappa-opioid receptor (KOPr) agonists have pre-clinical anti-cocaine and analgesic effects. However, side effects including sedation, dysphoria, aversion, anxiety and depression limit their therapeutic development. The unique structure of salvinorin A has been used to develop longer acting KOPr agonists. OBJECTIVES: We evaluate two novel C-2 analogues of salvinorin A, ethoxymethyl ether Sal B (EOM Sal B) and β-tetrahydropyran Sal B (β-THP Sal B) alongside U50,488 for their ability to modulate cocaine-induced behaviours and side effects, pre-clinically...
