While a large number of studies has examined the efficacy of opioid-sparing analgesics in adult surgical populations, fewer studies are available to guide postoperative pain treatment in pediatric patients. We systematically reviewed available publications on the use of systemic nonopioid agents for postoperative analgesia in pediatric surgical populations. A comprehensive literature search identified meta-analyses and randomized controlled trials (RCTs) assessing the effects of systemic, nonopioid agents on postoperative narcotic requirements or pain scores in pediatric surgical populations...

New M2 blockers effective against the ubiquitous amantadine-resistant S31N M2 mutation in influenza A are needed. Six copper complexes, 2, 4, 6, 8, 9, and 10, were synthesized and found to block both wild type and S31N M2. Free Cu(2+) also blocks M2 S31N but not S31N/H37A. The copper complexes do not block M2 H37A (either S31 or S31N). The complexes were effective against three influenza A strains in cell-culture assays, but less toxic to cells than CuCl2. For example 4, Cu(cyclooctylamineiminodiacetate), which was stable at pH > 4 in the buffers used, had an EC50 against A/Calif/07/2009 H1N1 of 0...

A 69-year-old Caucasian male with a 25-year history of paranoid schizophrenia was brought to the emergency department because of violence toward the staff in his nursing facility. He was diagnosed with a urinary tract infection and was admitted to the behavioral health unit for medication stabilization. History included a five-year state psychiatric hospital admission and nursing facility placement. Because of poor cognitive function, the patient was unable to corroborate medication history, so the pharmacy student on rotation performed an in-depth chart review...

Philippa Miller, Andrew Soundy
AIM: The clinical aim was to provide up-to-date evidence-based recommendations for the treatment of MS-related fatigue (MSRF). The scientific aim was to prioritise topics for future randomised clinical trials with sufficient power. METHODS: A systematic search of review based research that considered MSRF in adults (18years and over) was undertaken in May 2016. Data from reviews was extracted, critically appraised and synthesised using four specific techniques. RESULTS: A total of 24 reviews were identified (17 non-pharmacological, 5 pharmacological, 2 combining both), which contained 339 studies on interventions deigned to improve MSRF...

BACKGROUND: Influenza continues to have a substantial socioeconomic and health impact despite a long established vaccination programme and approved antivirals. Preclinical data suggest that combining antivirals might be more effective than administering oseltamivir alone in the treatment of influenza. METHODS: We did a randomised, double-blind, multicentre phase 2 trial of a combination of oseltamivir, amantadine, and ribavirin versus oseltamivir monotherapy with matching placebo for the treatment of influenza in 50 sites, consisting of academic medical centre clinics, emergency rooms, and private physician offices in the USA, Thailand, Mexico, Argentina, and Australia...

Memantine, an uncompetitive glutamatergic N-methyl-d-aspartate (NMDA) receptor antagonist, is widely used as a medication for the treatment of Alzheimer's disease (AD). We previously reported that chronic treatment of AD with memantine reduces the amount of insoluble β-amyloid (Aβ) and soluble Aβ oligomers in animal models of AD. The mechanisms by which memantine reduces Aβ levels in the brain were evaluated by determining the effect of memantine on Aβ aggregation using thioflavin T and transmission electron microscopy...

In recent years, a few of randomized controlled trials (RCTs) about amantadine for treating dyskinesia in Parkinson's disease (PD) were completed. Here, we conducted a systematic literature review about the clinical research to provide the updated evidence for treating dyskinesia. Electronic search of Medline, PubMed, Cochrane Library, and other databases up to May 2016 for relevant studies was performed. We selected the Unified Parkinson's Disease Rating Scale IV (UPDRS IV) and Dyskinesia Rating Scales (DRS) as efficacy outcomes of amantadine on dyskinesia...

Depression is a psychiatric disorder and chronic stress, leading to altered glucocorticoid secretion patterns, is one of the factors that induce depression. Our previous study showed that amantadine significantly attenuated the impairments of synaptic plasticity and cognitive function a rat model of CUS. However, little is known regarding the underlying mechanism. In the present study, the whole-cell patch-clamp technique was applied to examine the protection effect of amantadine on the hippocampus CA3-CA1 pathway...

PURPOSE OF REVIEW: Very few options exist for patients who survive severe traumatic brain injury but fail to fully recover and develop a disorder of consciousness (e.g. vegetative state, minimally conscious state). RECENT FINDINGS: Among pharmacological approaches, Amantadine has shown the ability to accelerate functional recovery. Although with very low frequency, Zolpidem has shown the ability to improve the level of consciousness transiently and, possibly, also in a sustained fashion...

The influenza A and B viruses are the primary cause of seasonal flu epidemics. Common to both viruses is the M2 protein, a homo-tetrameric transmembrane (TM) proton channel that acidifies the virion after endocytosis. Although influenza A M2 (AM2) and B M2 (BM2) are functional analogs, they have little sequence homology, except for a conserved HxxxW motif, which is responsible for proton selectivity and channel gating. Importantly, BM2 contains a second titratable histidine, His27, in the TM domain, which forms a reverse WxxxH motif with the gating tryptophan...

The first outbreak of influenza A(H3N2) occurred in 1968 and caused the third flu pandemic of the 20th century. It has affected multiple countries over time. The best strategy to reduce the burden of influenza is through vaccination whose efficacy varies with respect to the circulating strains. This study was performed to better understand the molecular evolution of influenza A(H3N2) and assess vaccine efficacy in Cameroon. Complete sequences of three gene segments were obtained from 2014 to 2016 influenza seasons in Cameroon...

The use of systematic approach for the analysis of mechanism of action of drugs at different levels of biological organization of organism is an important task in experimental and clinical pharmacology for drug designing and increasing the efficacy and safety of drugs. The analysis of published data on pharmacological effects of psychotropic drugs possessing immunomodulatory and/or antiviral properties have shown a correlation between central effects of examined drugs associated with the impact on the processes of neurogenesis of mature brain and survival of neurons, and their ability to alter levels of key proinflammatory cytokines...

Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual, and eating behaviors, are a serious and increasingly recognized complication in Parkinson's disease (PD), occurring in up to 20% of PD patients over the course of their illness. Related behaviors include punding (stereotyped, repetitive, purposeless behaviors), dopamine dysregulation syndrome (DDS) (compulsive medication overuse), and hobbyism (e.g., compulsive internet use, artistic endeavors, and writing). These disorders have a significant impact on quality of life and function, strain interpersonal relationships, and worsen caregiver burden, and are associated with significant psychiatric comorbidity...
