INTRODUCTION: Spinal anesthesia is considered the gold standard anesthetic technique for cesarean deliveries (CD) but is associated with a high rate of hypotension. The recent international consensus recommends continuous prophylactic phenylephrine infusion (PPI) administered throughout CD to prevent hypotension. However little information is available on the hemodynamic profiles of women with twin pregnancies as compared to singleton pregnancies perioperatively. Therefore, in this study we aim we compare maternal hemodynamic changes both intraoperatively and postoperatively with the use of the NICAS bio impendence monitor in healthy singleton versus twin parturients undergoing CD deliveries with spinal anesthesia with PPI...

INTRODUCTION: Spinal anesthesia for cesarean delivery is associated with high incidence of hypotension and is most often prevented by a prophylactic phenylephrine infusion (PPI). In this study, we aimed to identify maternal hemodynamic changes both intraoperatively and postoperatively with the use of the NICaS noninvasive cardiac output monitor in healthy singleton parturients undergoing cesarean delivery (CD) with spinal anesthesia and PPI. METHODS: Healthy term women undergoing spinal anesthesia for singleton CD were enrolled...

The sensitization of cough reflex observed in patients with gastroesophageal reflux disease (GERD) is attributed to activation of vagal C-fibers innervating the esophagus by acid, while the heartburn in GERD is mediated by esophageal acid sensitive C-fibers derived from (dorsal root ganglia) DRG. Here we explored the relationship between cough reflex sensitivity (CRS) and esophageal sensitivity to acid. We evaluated CRS to capsaicin inhalation and esophageal sensitivity to acid (intensity of heartburn evoked by esophageal infusions of acid pH = 3, 2 and 1) in patients with GERD and chronic heartburn before and 3 months after proton pump inhibitor (PPI) treatment...

Pharmacological manipulation of nitric oxide (NO) has been suggested as a promising treatment for schizophrenia symptoms. A single infusion of sodium nitroprusside, a NO donor with short half-life, was found to improve schizophrenia symptoms. However, an increasing number of preclinical studies have demonstrated the potential beneficial effects of both NO donors and inhibitors. We investigated the potential synergistic effect of sub-effective doses of the NO donor sodium nitroprusside or the NO inhibitor 7-Nitroindazole (7NI) combined with clozapine, a standard atypical antipsychotic, on counteracting amphetamine or MK-801-induced psychosis-like behaviors...

BACKGROUND: Endoscopic submucosal dissection (ESD) is a promising method for the resection of superficial gastric neoplasms. Vonoprazan is a novel potassium-competitive acid blocker (P-CAB) that is currently considered as a potential alternative to proton pump inhibitors (PPIs) for the treatment of acid-related diseases. However, the utility of vonoprazan in ESD-related ulcers is unclear. Therefore, we compared the short-term efficacies of vonoprazan and the PPI lansoprazole in ESD-related ulcer healing during the first two weeks following intervention...

Acute upper gastrointestinal haemorrhage due to peptic ulcer bleeding remains an important cause of emergency presentation and hospital admission. Despite advances in many aspects of management, peptic ulcer bleeding is still associated with significant morbidity, mortality, and healthcare costs. Comprehensive international guidelines have been published, but advances as well as controversies continue to evolve. Important recent advances include the evidence supporting a more restrictive transfusion strategy aiming for a target haemoglobin of 70-90 g/l...

The involvement of posterior cingulate cortex (PCC) on ketamine-induced psychosis relevant behaviors was investigated in rats. Bilateral infusion of muscimol, a GABAA receptor agonist, into the PCC significantly antagonized ketamine-induced deficit in prepulse inhibition of a startle reflex (PPI), deficit in gating of hippocampal auditory evoked potentials, and behavioral hyperlocomotion in a dose dependent manner. Local infusion of ketamine directly into the PCC also induced a PPI deficit. Systemic injection of ketamine (3mg/kg,s...

The presence of cirrhosis increases the mortality of patients with peptic ulcer bleeding (PUB). Both acute variceal bleeding (AVB) and PUB are associated with substantial mortality in cirrhosis. This multicenter cohort study was performed to assess whether the mortality of patients with cirrhosis with PUB is different from that of those with AVB. Patients with cirrhosis and acute gastrointestinal bleeding were consecutively included and treated with somatostatin and proton pump inhibitor infusion from admission and with antibiotic prophylaxis...

Upper gastrointestinal haemorrhage (UGIH) in severe dengue represents a clinical dilemma in term of management. The recommended treatment in dengue with UGIH involves blood product transfusion support and proton pump inhibitor (PPI) infusion. Despite being the mainstay of treatment in non-dengue UGIH, the role of endoscopic haemostatic intervention in severe dengue remains controversial. In the present report, we present a case of severe dengue complicated with upper gastrointestinal haemorrhage successfully underwent early therapeutic endoscopic intervention in a district hospital...

PURPOSE: The pharmacology, rationale, and dosing optimization strategies of proton pump inhibitors (PPIs) for the treatment of upper gastrointestinal bleeding (UGIB) are discussed. SUMMARY: In combination with endoscopic therapy, PPIs are the treatment of choice for UGIB. While the advent of PPIs has improved patient outcomes, controversy still exists over optimal PPI therapy for UGIB. Pharmacologic treatment in combination with endoscopic therapy has demonstrated improved outcomes in patients with nonvariceal UGIB...

Prepulse inhibition (PPI) is a behavioral test in which the startle reflex response to a high-intensity stimulus (pulse) is inhibited by the prior presentation of a weak stimulus (prepulse). The classic neural circuitry that mediates startle response is localized in the brainstem; however, recent studies point to the contribution of structures involved in higher cognitive functions in regulating the sensorimotor gating, particularly forebrain regions innervated by dopaminergic nuclei. The aim of the present study was to verify the role of dorsal striatum (DS) and dopaminergic transmitting mediated by D1 and D2 receptors on PPI test in rats...

Background: Previous studies suggested that opiate withdrawal may increase anxiety and disrupt brain-derived neurotrophic factor function, but the effects of i.v. morphine self-administration on these measures remain unclear. Methods: Adult male Sprague-Dawley rats were implanted with a catheter in the jugular vein. After 1 week of recovery, the animals were allowed to self-administer either i.v. morphine (0.5 mg/kg per infusion, 4 h/d) or saline in the operant conditioning chambers...

Subconvulsive hippocampal neural disinhibition, that is reduced GABAergic inhibition, has been implicated in neuropsychiatric disorders characterized by attentional and memory deficits, including schizophrenia and age-related cognitive decline. Considering that neural disinhibition may disrupt both intra-hippocampal processing and processing in hippocampal projection sites, we hypothesized that hippocampal disinhibition disrupts hippocampus-dependent memory performance and, based on strong hippocampo-prefrontal connectivity, also prefrontal-dependent attention...

Dystrobrevin-binding protein 1 (Dtnbp1) is one of the earliest identified schizophrenia susceptibility genes. Reduced expression of DTNBP1 is commonly found in brain areas of schizophrenic patients. Dtnbp1-null mutant mice exhibit abnormalities in behaviors and impairments in neuronal activities. However, how diminished DTNBP1 expression contributes to clinical relevant features of schizophrenia remains to be illustrated. Here, using a conditional Dtnbp1 knockout mouse line, we identified an in vivo schizophrenia-relevant function of DTNBP1 in pyramidal neurons of the medial prefrontal cortex (mPFC)...

BACKGROUND AND STUDY AIM: Previous studies have shown that both scheduled second-look endoscopy and high-dose continuous omeprazole infusion are effective in preventing peptic ulcer rebleeding. The aim of this noninferiority trial was to compare the efficacy of these two strategies for the prevention of rebleeding following primary endoscopic hemostasis. PATIENTS AND METHODS: Consecutive patients who received endoscopic treatment for bleeding peptic ulcers (actively bleeding, with nonbleeding visible vessels) were randomized to two treatment groups following hemostasis...

OBJECTIVES: High-dose intravenous proton pump inhibitors (PPIs) post endoscopy are recommended in non-variceal upper gastrointestinal bleeding (UGIB), as they improve outcomes of patients with high-risk lesions. Determine the budget impact of using different PPI regimens in treating non-variceal UGIB, including pre- and post-endoscopic use, continuous infusion (high dose), and intermittent bolus (twice daily) dosing. METHODS: A budget impact analysis using a decision model informed with data from the literature adopting a US third party payer's perspective with a 30-day time horizon was used to determine the total cost per patient (US$2014) presenting with acute UGIB...

UNLABELLED: The neurobiology of post-traumatic stress disorder (PTSD) remains unclear. Intense stress promotes PTSD, which has been associated with exaggerated startle and deficient sensorimotor gating. Here, we examined the long-term sequelae of a rodent model of traumatic stress (repeated predator exposure) on amygdala systems that modulate startle and prepulse inhibition (PPI), an operational measure of sensorimotor gating. We show in rodents that repeated psychogenic stress (predator) induces long-lasting sensitization of basolateral amygdala (BLA) noradrenergic (NE) receptors (α1) via a corticotropin-releasing factor receptor 1 (CRF-R1)-dependent mechanism, and that these CRF1 and NE α1 receptors are highly colocalized on presumptive excitatory output projection neurons of the BLA...
