Noelia I Zanetti, Adriana A Ferrero, Néstor D Centeno
The aims of this study were to detect and quantify fluoxetine, an antidepressant, from entomological samples. Larvae, pupae and adults of Dermestes maculatus (Coleoptera, Dermestidae) were reared on pig muscle previously treated with fluoxetine. The concentration selected, 2000mg/kg, emulates a fluoxetine overdose lethal to humans and laboratory animals. Thirty larvae on the fourth and fifth stages, 50 adults and several exuviae were analyzed for fluoxetine content. Detection of fluoxetine was performed by UV spectrophotometry at 270 and 277nm...

REVIEW
Benjamin L Woolbright, Hartmut Jaeschke
Drug-induced acute liver failure carries a high morbidity and mortality rate. Acetaminophen overdose is the number one cause of acute liver failure and remains a major problem in Western medicine. Administration of N-acetyl cysteine is an effective antidote when given before the initial rise in toxicity; however, many patients present to the hospital after this stage occurs. As such, treatments which can alleviate late-stage acetaminophen-induced acute liver failure are imperative. While the initial mechanisms of toxicity are well described, a debate has occurred recently in the literature over whether or not there exists a second phase of injury, mediated by inflammatory processes...

Non vitamin-K oral anticoagulants (NOACs) are direct and specific inhibitors of the coagulation factors IIa (dabigatran) and Xa (apixaban, rivaroxaban, edoxaban) which share many pharmacokinetic properties. However, indications are lacking regarding the use of NOACs during thrombolysis, surgery and bleeding events. Areas covered: In this paper, the authors retrospectively analyzed the relevant literature on the NOACs using the PubMed and Google Scholar databases. Expert Commentary: Although warfarin is effective in cardioembolic stroke prevention, easier handling and more favorable risk-benefit profile often render NOACs a more preferable therapy choice for neurologists...

Risky, non-dependent alcohol use is prevalent in the United States, affecting 25% of adults (Centers for Disease Control and Prevention, 2014b). Massachusetts has higher rates of alcohol use and binge drinking than most states (Substance Abuse and Mental Health Services Administration, 2015). Serious physical, social, and economic consequences result. Excessive alcohol use contributes to cancer, cardiovascular disease, sleep disorders, birth defects, motor vehicle injuries, and suicide, and it complicates management of chronic illnesses (Green, McKnight-Eily, Tan, Mejia, & Denny, 2016; Laramee et al...

Dabigatran is an oral, direct thrombin inhibitor approved by international regulatory agencies for stroke prevention in patients with paroxysmal or persistent non-rheumatic atrial fibrillation (AF). The benefits of dabigatran are widely described, but its use in the geriatric population is not without risk. Chronic kidney disease is a common comorbidity with AF, and thus frequent checks of renal function in elderly patients are recommended. We report a case of dabigatran intoxication in an elderly man affected by heart failure and worsening renal function, who developed acute hepatitis and coma, which was successfully treated with continuous veno-venous hemodiafiltration...

Overdose of acetaminophen (APAP) is often associated with hepatotoxicity. Carfilzomib (CFZ) shows multiple pharmacological activities including anti-inflammatory potential. Therefore, this study was undertaken to evaluate the possible therapeutic effects of CFZ against APAP-induced hepatotoxicity. Hepatotoxicity was induced by administration of APAP (350 mg/kg, intraperitoneal). Mice were given CFZ (0.125, 0.25, or 0.5 mg/kg, intraperitoneal) 1.5 h after APAP administration. Animals were sacrificed on 6 h and blood and liver tissue samples were collected for analysis...

Agonists targeting the kappa opioid receptor (KOR) have been promising therapeutic candidates because of their efficacy for treating intractable itch and relieving pain. Unlike typical opioid narcotics, KOR agonists do not produce euphoria or lead to respiratory suppression or overdose. However, they do produce dysphoria and sedation, side effects that have precluded their clinical development as therapeutics. KOR signaling can be fine-tuned to preferentially activate certain pathways over others, such that agonists can bias signaling so that the receptor signals through G proteins rather than other effectors such as βarrestin2...

A 67-year critically ill patient suffered from a hypertensive crisis (200 mm Hg) because of a norepinephrine overdose. The overdose occurred when the clinician exchanged an almost-empty syringe and the syringe pump repeatedly reported an error. We hypothesized that an object between the plunger and the syringe driver may have caused the exertion of too much force on the syringe. Testing this hypothesis in vitro showed significant peak dosing errors (up to +572%) but moderate overdose (0.07 mL, +225%) if a clamp was used on the intravenous infusion line and a large overdose (0...

Yu-Ping Chang, Peggy Compton
The United States is amid an epidemic of prescription opioid drug abuse, bringing with it not only high rates of overdose, but growing rates of heroin abuse and addiction. Liberal opioid drug prescribing on the part of well-meaning clinicians has in part fueled this epidemic, being correlated to opioid death and addiction treatment admission rates. Misuse and abuse of prescription opioid drugs is greatest among young adults (ages 18 to 25); however, the fastest growing age group for opioid drug misuse/abuse is older (ages 50 to 64)...

Sahil Chaudhary, Peggy Compton
BACKGROUND: Ongoing opioid analgesic use in patients suffering from chronic non-malignant pain (CNMP) has been associated with the development of opioid misuse, abuse, addiction, and overdose. To prevent these adverse outcomes, it is important that family nurse practitioners (FNPs) implement recommended risk mitigation practices (RMPs) when treating CNMP patients with opioids. METHODS: A national sample of 856 FNPs was invited to answer an online survey about their utilization of opioids and RMPs in treating CNMP...

BACKGROUND: Mounting evidence based on retrospective and global assessments has established associations between prescription drug misuse and illicit drug use, alcohol abuse, mental health problems, risky sexual behaviors, and overdose deaths. However, there is a notable absence of identified risk and protective factors for an individual's likelihood of engaging in misuse in real-world environments. METHODS: Using an experience sampling approach, we collected repeated moments of young adults' (n = 95 participants drawn from 49 romantic couples) prescription drug misuse instances in daily life, and tested multiple factors associated with the misuse...

BACKGROUND: Heroin use by non-injecting routes of administration (snorting, swallowing, "chasing the dragon") is considered to be safer but is not risk-free for fatal overdose or serious side effects. We report the case of an adolescent who was transferred unconscious to the emergency department after heroin inhalation. Description of the case: A 17-year-old male was transferred to the emergency department unconscious (Glasgow coma scale: 6/15) after heroin inhalation. He was treated with non-rebreather mask and intravenous infusion of naloxone with gradual improvement of consciousness and arterial blood gasses...
