INTRODUCTION: In spite of advances in understanding and technology, postoperative pain remains poorly treated for a significant number of patients. In colorectal surgery, the need for developing novel analgesics is especially important. Patients after bowel surgery are assessed for rapid return of bowel function and opioids worsen ileus, nausea and constipation. We describe a prospective, double-blind, parallel group, placebo-controlled randomised controlled trial testing the hypothesis that a novel analgesic drug, VVZ -149, is safe and effective in improving pain compared with providing opioid analgesia alone among adults undergoing laparoscopic colorectal surgery...

We investigate the behavior of a model neuron that receives a biophysically realistic noisy postsynaptic current based on uncorrelated spiking activity from a large number of afferents. We show that, with static synapses, such noise can give rise to inverse stochastic resonance (ISR) as a function of the presynaptic firing rate. We compare this to the case with dynamic synapses that feature short-term synaptic plasticity and show that the interval of presynaptic firing rate over which ISR exists can be extended or diminished...

Ribavirin (RBV) is a synthetic guanosine analog that is used as a drug against various viral diseases in humans. The in vitro antiviral effects of ribavirin against porcine viruses were demonstrated in several studies. The purposes of this study were to evaluate the adverse effects and pharmacokinetics of ribavirin following its intramuscular (IM) injection in pigs. Ribavirin was formulated as a double-oil emulsion (RBV-DOE) and gel (RBV-Gel), which were injected into the pigs as single-dose IM injections...

The retinae of many bird species contain a depression with high photoreceptor density known as the fovea. Many species of raptors have two foveae, a deep central fovea and a shallower temporal fovea. Birds have six types of photoreceptors: rods, active in dim light, double cones that are thought to mediate achromatic discrimination, and four types of single cones mediating color vision. To maximize visual acuity, the fovea should only contain photoreceptors contributing to high-resolution vision. Interestingly, it has been suggested that raptors might lack double cones in the fovea...

BACKGROUND: Patients are educated about their illness and its treatment at the time of diagnosis. However, little is known about how much of this education is retained and how it influences knowledge about, attitudes toward, and experiences with medication in antidepressant-naive patients with depression. METHODS: Antidepressant-naive outpatients with International Classification of Diseases-10 dysthymia or mild to moderate depression, who were advised antidepressant monotherapy, were randomized to control (n = 22) or intervention (n = 17) groups...

BACKGROUND AND AIMS: Alcohol use disorders (AUDs) are common among people with chronic hepatitis C (HCV) and accelerate the development of fibrosis and cirrhosis caused by HCV. Baclofen, a gamma-aminobutyric acid (GABA) beta-receptor agonist, differs from medications for AUDs currently approved by the United States (US) Federal Drug Administration (FDA) as it is metabolized primarily through the kidneys. The primary outcome of this study was to compare baclofen with a placebo in the percentage of days abstinent from alcohol...

PURPOSE: Depression is common among people living with HIV, and it is associated with impaired work functioning. However, little research has examined whether depression alleviation improves work-related outcomes in this population, which is the focus of this analysis. METHOD: A sample of 1028 depressed HIV clients in Uganda enrolled in a comparative trial of depression care models and were surveyed over 12 months. Serial regression analyses examined whether depression alleviation (measured by the nine-item Patient Health Questionnaire) was associated with change in self-reported weekly amount of hours worked and income earned, and whether these relationships were mediated by change in work-related self-efficacy...

BACKGROUND: HIV-infected adults initiating antiretroviral therapy (ART) in sub-Saharan Africa continue to experience high rates of morbidity and mortality during the initial months of treatment. Observational studies in high-income and resource-limited settings indicate that HIV-infected adults with low vitamin D levels may be at increased risk of mortality, HIV disease progression, and incidence of pulmonary tuberculosis (TB). As a result, vitamin D3 supplementation may improve survival and treatment outcomes for HIV-infected adults initiating ART...

BACKGROUND: Men with biochemical recurrence of prostate cancer following local therapies often use natural supplements in an attempt to delay metastases and/or avoid the need for more aggressive treatments with undesirable side-effects. While there is a growing body of research into phytotherapeutic agents in this cohort, with some promising results, as yet no definitive recommendations can be made. This pilot study was undertaken to assess the feasibility of a fully-powered study to examine the effects of this phytotherapeutic intervention (containing turmeric, resveratrol, green tea and broccoli sprouts) on PSA doubling time in men with biochemical recurrence with a moderate PSA rise rate...

Emotional distress has been associated with a poorer prognosis in myocardial infarction patients. Elevated adrenocorticotrophic hormone (ACTH), lower cortisol, dehydroepiandrosterone sulfate (DHEAS) and cortisol:DHEAS, as measures of emotional distress, might correlate with silent myocardial ischemia (SMI) and workload. Thus, we assessed the relationship between emotional distress, SMI and double product (systolic blood pressure (SBP) × heart rate). Cross-sectional South African biethnic single-set cohorts (N=378), aged 44...

BACKGROUND: Preliminary studies report no negative and a possible positive impact of deep brain stimulation (DBS) on cognition of patients with treatment-resistant depression (TRD). However, these studies neither controlled for practice effects nor compared active with sham stimulation. METHOD: To address these limitations, we compared 25 TRD patients, who underwent DBS of the ventral anterior limb of the internal capsule (vALIC), with 21 healthy controls (HCs) matched on gender, age and education level...

In randomized controlled trials (RCTs), medication side effects may lead to beliefs that one is receiving the active intervention and enhance active treatment responses, thereby majoring drug-placebo differences. We tested these hypotheses with an experimental double-blind RCT of a nonsteroidal anti-inflammatory medication (NSAID) with and without the addition of atropine to induce side effects. One hundred healthy volunteers were told they would be randomized to either combined analgesics that might produce dry mouth or inert placebos...

Approximately 40% of patients treated for depression do not respond to a trial of an antidepressant. The aim of the proposed study was to evaluate the efficacy and safety of switching to vilazodone in patients with major depressive disorder who are unresponsive or only partially responsive to a trial of citalopram. Seventy-nine adults with major depressive disorder were enrolled in an open-label study of citalopram (20 mg/day) for 6 weeks. Those still symptomatic after 6-weeks of citalopram were randomly assigned to either a higher dose of citalopram (40 mg/day) or to vilazodone in a double-blind trial for 6 weeks...

BACKGROUND: Bipolar disorder is a chronic illness with a 2-year recurrence rate of approximately 50% among individuals receiving treatment in the community. The aim of this 18-month, open-label, continuation study was to evaluate the long-term safety and effectiveness of lurasidone in patients who initially presented with a major depressive episode associated with bipolar disorder, and who had completed at least 6 months of initial treatment with lurasidone. METHODS: Patients with bipolar I depression were enrolled in one of three 6-week, double-blind, placebo-controlled trials (monotherapy with lurasidone, 1 study; adjunctive therapy with lurasidone; and lithium or valproate, 2 studies)...

This study investigates paternal brain function with the hope of better understanding the neural basis for variation in caregiving involvement among men. The neuropeptides oxytocin (OT) and vasopressin (AVP) are implicated in paternal caregiving in humans and other species. In a double-blind, placebo-controlled, within-subject pharmaco-functional MRI experiment, we randomized 30 fathers of 1-2year old children to receive either 24IU intranasal OT before one scan and placebo before the other scan (n=15) or 20IU intranasal AVP before one scan and placebo before the other scan (n=15)...

Stress-induced disturbance of the hypothalamic-pituitary-adrenal (HPA) axis is strongly implicated in incidence of mood disorders. A heightened neuroinflammatory response and oxidative stress play a fundamental role in the dysfunction of the HPA axis. We have previously demonstrated that iptakalim (Ipt), a new ATP-sensitive potassium (K-ATP) channel opener, could prevent oxidative injury and neuroinflammation against multiple stimuli-induced brain injury. The present study was to demonstrate the impacts of Ipt in stress-induced HPA axis disorder and depressive behavior...

Recent intensive development of nanotechnology has broadened the use of noble metal nanocolloids in alternative medicine. Meanwhile, silver and copper nanoparticles are tested as potential feed additives in pig farming. Experiments on rodents prove that metal nanocolloids easily interact with macrophages and lymphocytes, although the specific nature of pigs' immune system means that rodent tests may not reflect fully the responsiveness of porcine T cells. Our purpose was to demonstrate the effect of a commercial gold nanocolloid on percentages and proliferation of T lymphocyte subpopulations and on IL-2 and IL-10 synthesis in porcine peripheral blood mononuclear cells tested in vitro...

PURPOSE OF REVIEW: To review some aspects of the relationship between epilepsy and depression that have recently received increasing attention and may become major research topics in the near future. RECENT FINDINGS: Epidemiological studies show that depression and suicide are, in some cases, premorbid symptoms preceding the onset of the epilepsy. Suicide is also three times more frequent in epilepsy than in the general population. Reliable screening instruments for depression and suicidality in patients with epilepsy are now available but data from real life clinical settings are needed to develop shared clinical pathways between neurology and psychiatry...
