  CONCLUSIONS These data provide behavioral economic evidence that cannabis access may modestly reduce demand for opioids in persons who have pain. Additional clinical studies that evaluate the analgesic effects of cannabis and cannabis-opioid effects on pain are warranted.PURPOSE Clinical trials serve as a critical source of information to guide evidence-based practices in urology. Conversely, trials that are abandoned consume significant resources and results are under-reported in the literature. MATERIALS AND METHODS ClinicalTrials.gov was queried for urology trials from 2006-2016. Trials were screened by two screeners for applicability to urology and disputes were resolved by a third independent reviewer. 1,340 trials met final inclusion criteria (722 successful trials, 618 failed trials). Univariable analysis utilized Fisher's Exact, Chi-Squared, and Wilcoxon Rank-Sum tests. Trial characteristics, including AUA section, phase, subspecialty, intervention type, source of funding, and randomization were examined for association with failure using multivariable logistic regression. RESULTS Trial failure is associated with Oncology subspecialty (Adjusted Odds Ratio [AOR] 2.25, 95% CI 1.60-3.18), Infertility/Andrology subspecialty (AOR 4.99, CI 1.60-17.61), device trials (AOR 1.64, CI 1.00-2.70), and combination funding by industry/government/grants (AOR 3.13, CI 2.21-4.48). Clinical trials in AUA sections were less likely to fail than international and multi-sectional trials. Among trials that failed, poor accrual was the primary reason for trial failure, comprising 41% of all failures. Other reasons for failure include inadequate budget (9%), sponsor cancellation (7%), poor interim results (7%), and toxicity (3%). CONCLUSIONS Despite their significance, many urological trials fail prematurely due to poor accrual. Complex features inherent to Oncology, Andrology/Infertility, devices, and multi-sectional trials pose significant barriers to success.The parafacial respiratory group (pFRG), located in the lateral aspect of the rostroventral lateral medulla, has been described as a conditional expiratory oscillator that emerges mainly in conditions of high metabolic challenges in order to increase breathing. The convergence of inhibitory and excitatory inputs to pFRG and the generation of active expiration may be more complex than previously thought. We hypothesized that the medullary raphe, a region that has long been described to be involved in breathing activity, is also responsible for the expiratory activity under hypercapnic condition. To test this hypothesis, we performed anatomical and physiological experiments in urethane-anesthetized adult male Wistar rats. Our data showed anatomical projections from serotonergic (5-HT) and GABAergic neurons of Raphe Magnus (RMg) and Obscurus (ROb) to the pFRG region. Pharmacological inhibition of RMg or ROb with muscimol (60 pmol/30 nL) did not change the frequency or amplitude of diaphragm activity and did not generate active expiration. However, under hypercapnia (9-10% CO2), the inhibition of RMg or ROb increased the amplitude of abdominal activity, without changing the increased amplitude of diaphragm activity. Depletion of serotonergic neurons with Saporin Anti-SERT injections into ROb and RMg did not increase the amplitude of abdominal activity during hypercapnia. These results show that the presumably GABAergic neurons within the RMg and ROb may be the inhibitory source to modulate the activity of pFRG during hypercapnia condition.Introduction Cannabis use results in elevation of heart rate and blood pressure immediately after use, primarily due to sympathetic nervous system stimulation and parasympathetic nervous system inhibition. These effects may precipitate cardiac dysrhythmia. The objective of our study was to analyze systematically the pertinent medical literature regarding the putative association between cannabis use and cardiac dysrhythmia.Methods We queried PubMed, Google Scholar, and OpenGrey, and reviewed results for relevance. We graded clinical trials, observational and retrospective studies, case series and reports using Oxford Centre for Evidence-Based Medicine guidelines.Results The relevant publications identified included one Level I systematic review and meta-analysis of six human studies, 16 Level II studies with 6,942 subjects, nine Level III studies with 3,797,096 subjects and two systematic and scoping reviews with 30 cases. Cannabis-induced tachycardia was highlighted in 17 of 28 (61%) Level I-III articles folardiographic changes included ST segment elevation (29%), Brugada pattern in leads V1, V2 (14%), and right bundle branch block (12%).  https://www.selleckchem.com/products/Cyclopamine.html  There were eight cases of cardiac arrest, of whom five expired.Conclusion Cannabis use is associated with increased risk of cardiac dysrhythmia, which is rare but may be life-threatening. Clinicians and nurses should inquire about acute and chronic cannabis use in their patients presenting with tachycardia, bradycardia, dysrhythmia, chest pain, and/or unexplained syncope. Patients who use cannabis should be educated on this deleterious association, especially those with underlying cardiac disease or risk factors.Introduction Lung cancer is the most prevalent malignant tumors worldwide.  https://www.selleckchem.com/products/Cyclopamine.html  Over the past decade, the emergence of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) has ushered in a new era of lung cancer treatment. Therefore, clinical trials investigating the efficacy and safety of these drugs are important.Areas covered This review provides an overview on the safety of three classes of EGFR-TKIs and discusses the adverse events (AEs) and reactions reported in the literature.Expert opinion EGFR-TKIs significantly improve progression-free survival and overall survival in non-small cell lung cancer (NSCLC) patients with an activating mutation of EGFR. However, EGFR-TKIs also block the EGFR-regulating pathways in the skin and gastrointestinal tract and cause AEs, including diarrhea, liver toxicity, skin disease, stomatitis, interstitial lung disease, and ocular toxicity, which have detrimental effects on quality of life and drug compliance. Clinicians should understand how to prevent and control these adverse reactions, which can often be achieved by dose reduction, discontinuation of treatment, or switching to another drug.
