BACKGROUND: Novel psychoactive substances (NPS) are new narcotic or psychotropic drugs that are not controlled by the United Nations drug convention that may pose a serious public health threat due to their wide availability for purchase on the internet and in so called "head shops." Yet, the extent of their global use remains largely unknown. The aim of this study is to conduct a systematic review of the prevalence of NPS use in non-clinical populations. METHODS: This is a systematic review of observational studies...

BACKGROUND: A safe and effective method of multilevel thoracic pain control remains an elusive goal in patients undergoing the Nuss procedure. The aim of our study was to develop a nonopioid centered approach using a novel regional technique as part of a quality improvement initiative. METHODS: The proposed ultrasound-guided technique positions multi-perforated soaker catheter deep to the paraspinal muscles from T2 to T11. The project was conducted in two phases...

The use of opioids for the treatment of chronic non-cancer pain is growing at an alarming rate. Opioid-induced bowel dysfunction (OBD) is a common adverse effect of long-term opioid treatment manifesting as constipation, nausea, and vomiting. These effects are primarily mediated by peripheral μ-opioid receptors with resultant altered GI motility and function. As a result, patients may present with opioid-induced constipation (OIC), opioid-induced nausea and vomiting (OINV), and/or narcotic bowel syndrome (NBS)...

Modified Early Warning Scores (MEWS) provide real-time vital sign (VS) trending and reduce ICU admissions in post-operative patients. These early warning calculations classically incorporate oxygen saturation, heart rate, respiratory rate, systolic blood pressure, and temperature but have not previously included end-tidal CO2 (EtCO2), more recently identified as an independent predictor of critical illness. These systems may be subject to failure when physiologic data is incorrectly measured, leading to false alarms and increased workload...

Cocaine is a highly addictive narcotic associated with dendritic spine plasticity in the striatum. However, it remains elusive whether cocaine modifies spines in a cell type-specific or region-specific manner or whether it alters different types of synapses in the brain. In addition, there is a paucity of data on the regulatory mechanism(s) involved in cocaine-induced modification of spine density. In the current study, we report that cocaine exposure differentially alters spine density, spine morphology, and the types of synapses in hippocampal and cortical neurons...

So far, in sports drug testing compounds of different classes are processed and measured using different screening procedures. The constantly increasing number of samples in doping analysis, as well as the large number of substances with doping related, pharmacological effects require the development of even more powerful assays than those already employed in sports drug testing, indispensably with reduced sample preparation procedures. The analysis of native urine samples after direct injection provides a promising analytical approach, which thereby possesses a broad applicability to many different compounds and their metabolites, without a time-consuming sample preparation...

Opioids are important for surgical pain control but may not be appropriate for patients with narcotic abuse histories or opioid intolerance. We describe a laparoscopic bilateral inguinal herniorrhaphy performed without perioperative or postoperative narcotics. Postoperative analgesia involves a novel technique using 2 different bupivacaine formulations that act synergistically to avoid lag time and provide extended pain relief during the acute surgical recovery phase.

REVIEW
Paul C Mayor, Shashikant Lele
Photodynamic therapy (PDT) is a treatment modality used in the management of solid tumor malignancies that employs the use of a photosensitizing agent, a light source and oxygen in order to illicit a direct cytotoxic effect. Its use in gynecologic malignancies is somewhat novel and has been used for palliative and curative intent. At the Roswell Park Cancer Institute, the use of PDT in the management of gynecologic cancers began in the mid 1980s and since that time 35 patients have received PDT as a treatment for recurrent or metastatic cutaneous and vulvar, vaginal, anal, and cervical recurrences...

Although some novel psychoactive substances (NPS) are newly discovered chemicals, others are traditional or indigenous substances that are introduced to new markets. One of these latter substances is a plant many people refer to as kratom. Indigenous to Southeast Asia and used for a variety of instrumental and recreational purposes, kratom has recently become available to Western drug users. Kratom is somewhat unique in that the plant contains two different psychoactive chemicals, which have both stimulant (mitragynine) and narcotic (7-hydroxymitragynine) properties...

BACKGROUND: Inguinodynia, defined as pain lasting >3 months after inguinal hernia repair, remains the major complication of hernia operation. We sought to determine the effect of direct perineural infiltration on acute pain and inguinodynia after open inguinal hernia repair. METHODS: Patients who presented with an inguinal hernia at a university teaching hospital were evaluated prospectively and randomized to either (1) percutaneous ilioinguinal nerve block or (2) percutaneous ilioinguinal nerve block with additional perineural infiltration of the ilioinguinal, iliohypogastric, genitofemoral nerves...

BACKGROUND: Prescription narcotic overdoses and abuse have reached alarming numbers. To address this epidemic, integrated clinical decision support within the electronic medical record (EMR) to impact prescribing behavior was developed and tested. METHODS: A multidisciplinary Expert Panel identified risk factors for misuse, abuse, or diversion of opioids or benzodiazepines through literature reviews and consensus building for inclusion in a rule within the EMR. We ran the rule "silently" to test the rule and collect baseline data...

PURPOSE OF REVIEW: To summarize observations in clinical chronic pancreatitis in the past year. RECENT FINDINGS: A predisposing genetic mutation was identified in 67% of cases of pediatric chronic pancreatitis. A novel susceptibility gene involving a hybrid allele is associated with idiopathic chronic pancreatitis. ABO blood type B and FUT2 nonsecretor status is associated with asymptomatic hyperlipasemia and chronic pancreatitis. Alcohol consumption impairs cystic fibrosis transmembrane conductance regulator (CFTR) activity leading to decreased bicarbonate secretion and patients with susceptible CFTR mutations can develop clinical pancreatitis...

A novel sonocatalyst, Er(3+):Y3Al5O12/KNbO3 composite, was synthesized, and then, characterized by X-ray diffractometer (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). In order to evaluate the sonocatalytic activity of prepared Er(3+):Y3Al5O12/KNbO3 composite, the sonocatalytic degradation of ketamine, a kind of narcotic drug, was studied. In addition, some influencing factors such as mass ratio, heat-treated temperature and heat-treated time on the sonocatalytic activity of prepared Er(3+):Y3Al5O12/KNbO3 powders and ultrasonic irradiation time on the sonocatalytic degradation of ketamine were examined by using GC-MS machine...

REVIEW

Agitation and aggression are common neuropsychiatric symptoms of Alzheimer's disease and are highly prevalent in people with dementia. When pharmacological intervention becomes necessary, current clinical practice guidelines recommend antipsychotics, cholinesterase inhibitors, and some antidepressants. However, those interventions have modest to low efficacy, and those with the highest demonstrated efficacy have significant safety concerns. As a result, current research is focusing on novel compounds that have different mechanisms of action and that may have a better balance of efficacy over safety...

BACKGROUND: Percutaneous endovascular aneurysm repair (PEVAR) continues to evolve. Device profiles continue to decline, further reducing the physiological insult of the procedure. Anesthesia, however, has not evolved with a large proportion of patients continuing to receive general anesthesia for their increasingly less invasive procedures. We report on a novel anesthetic technique providing outstanding anesthesia in patients undergoing PEVAR in an outpatient setting. The total anesthesia used was remarkably cost effective...

Palmitoylethanolamide (PEA), a special food for medical purposes, has anti-inflammatory and neuroprotective effects. Nevertheless, PEA lacks direct ability to prevent free radical formation. Polydatin (PLD), a natural precursor of resveratrol, has antioxidant activity. The combination of PEA and PLD could have beneficial effects on oxidative stress induced by inflammatory processes. In the present study, we compared the effects of micronized PEA (PEA-m) and PLD association (PEA-m+PLD) with a new co-micronized composite containing PEA and PLD (m(PEA/PLD)) in the rat paw model of carrageenan (CAR)-induced acute inflammation...

Alena Celsie, Donald Mackay, J Mark Parnis, Jon A Arnot
A novel dynamic fugacity-based model is described, developed, and tested that simulates the uptake of narcotic organic chemicals in fish from water as occurs in aquatic bioconcentration and toxicity tests. The physiologically based toxicokinetic model treats the time course of chemical distribution in 4 compartments (tissue groups) in the fish, including the liver, in which biotransformation may occur. In addition to calculating bioconcentration and toxicokinetics, 5 possible toxic endpoints are defined corresponding to chemical concentration, fugacity, or activity reaching a critical value that causes 50% mortality...

UNLABELLED: WHAT IS KNOWN ON THE SUBJECT?: Novel psychoactive substances (NPS) include synthetic drugs mimicking the effects of illicit drugs, e.g. synthetic cannabinoids, and herbs such as Salvia divinorum. NPS are substances that can trigger hallucinations and other effects altering the mind, and are currently uncontrolled by the United Nations' 1961 Narcotic Drugs/1971 Psychotropic Substances Conventions. NPS affect brain chemistry that induces the psychoactive effects, such as hallucinations and feeling 'high'...

Diethylhexyl phthalate (DEHP) is considered to be an endocrine disruptor, which unlike other chemicals that have either non-specific (e.g., narcotics) or more generalized reactive modes of action, affect the Hypothalamic-pituitary-gonadal (HPG) axis and tend to have specific interactions with particular molecular targets within biochemical pathways. Responding to this challenge, a novel method for deriving predicted no-effect concentration (PNEC) and probabilistic ecological risk assessment (PERAs) for DEHP based on long-term exposure to potentially sensitive species with appropriate apical endpoints was development for protection of Chinese surface waters...
