Tramadol, one of the most commonly abused drugs in Middle East, impacts spermatogenesis and disturbs reproductive hormones in animal studies. We aimed to investigate tramadol impact on sperm quality and on levels of testosterone, prolactin and gonadotropins, in tramadol abusers (n = 30) to age-matched control (n = 30). Abusers had significantly low percentages of sperm motility, normal forms and vitality compared with control (95% CI -40.7 to -19.3, -13.5 to -9.3 and -31.9 to -9.7 respectively). Hypoandrogenism (95% CI -4...

Cytochrome (CYP) 450 isoenzymes are the basic enzymes involved in Phase I biotransformation. The most important role in biotransformation belongs to CYP3A4, CYP2D6, CYP2C9, CYP2C19 and CYP1A2. Inhibition and induction of CYP isoenzymes caused by drugs are important and clinically relevant pharmacokinetic mechanisms of drug interaction. Investigation of the activity of CYP isoenzymes by using phenotyping methods (such as the determination of the concentration of specific substrates and metabolites in biological fluids) during drug administration provides the prediction of negative side effects caused by drug interaction...

PURPOSE: Obstructive sleep apnea (OSA) is a risk factor for complications with postoperative opioid use, and in those patients with known or suspected OSA, minimization of postoperative opioids is recommended. We hypothesize that despite these recommendations, surgical patients with known or suspected OSA are prescribed postoperative opioids at hospital discharge at similar doses to those without OSA. METHODS: This was a retrospective analysis of the electronic health records of surgical patients from 1 November 2016 to 30 April 2017 at a single academic institution...

BACKGROUND: Immune surveillance acts as a defense mechanism in cancer, and its disruption is involved in cancer progression. DNA methylation reflects the phenotypic identity of cells and recent data suggested that DNA methylation profiles of T cells and peripheral blood mononuclear cells (PBMC) are altered in cancer progression. METHODS: We enrolled 19 females with stage 1 and 2, nine with stage 3 and 4 and 9 age matched healthy women. T cells were isolated from peripheral blood and extracted DNA was subjected to Illumina 450 K DNA methylation array analysis...

Spermatozoa are specialised cells with low RNA content as compared to somatic cells. The suitable sperm RNA extraction and enrichment protocols for downstream applications are available for human, cattle, stallion and mouse but not for buffalo spermatozoa. Therefore, the present work was conducted to find out suitable colloidal solution for sperm purification and appropriate protocol for sperm RNA extraction and enrichment/amplification of RNA. For purification, we used PVP-coated silica colloidal solution (PVP-Si), silane-coated silica colloidal solution (Silane-Si) and iodixanol...

Nontyphoidal Salmonella (NTS) causes an estimated 1.2 million illnesses, 23,000 hospitalizations, and 450 deaths each year in the United States. Decreased susceptibility to ciprofloxacin (DSC) has historically been associated with chromosomal mutations (QRDR), but plasmid-mediated quinolone resistance (PMQR) genes are increasing. To investigate DSC among serotype Newport, we examined 40 isolates with DSC from 1996-2016. Thirty isolates (71%) contained the PMQR gene, qnrB , and eight isolates (19%) contained a QRDR...

Public health interventions to increase supermarket access assume that shopping in supermarkets is associated with healthier food purchases compared to other store types. To test this assumption, we compared purchasing patterns by store-type for certain higher-calorie, less healthy foods (HCF) and lower-calorie, healthier foods (LCF) in a sample of 35 black women household shoppers in Philadelphia, PA. Data analyzed were from 450 food shopping receipts collected by these shoppers over four-week periods in 2012...

Hypoplastic left heart syndrome (HLHS) is a highly resource-intensive diagnosis. Geographic variation in cost and length of stay (LOS) in HLHS is not well described. Neonates diagnosed with HLHS between 2000 and 2012 were identified using the Kids' Inpatient Database. Hospitalizations were stratified into two groups: (1) birth and (2) secondary. United States regional differences in hospital charges and LOS were compared using adjusted linear regression. Of 2431 birth hospitalizations, 449 neonates (18.5%) died while inpatient and mortality rates differed by region (p = 0...

REVIEW
Sameer Hassamal, Karen Miotto, William Dale, Itai Danovitch
Tramadol is commonly prescribed for pain control because it presents a lower risk for addiction and respiratory depression compared to other opioids. However, tramadol's serotonin and norepinephrine reuptake inhibitory effects result in a unique adverse effect profile. Two such adverse events are serotonin syndrome and seizures. The prevalence of tramadol-induced serotonin syndrome and seizures is modest in the general population but if left untreated, the morbidity and mortality can be high, and therefore prompt recognition and management is essential...

Kui Kai Lau, Caroline E Lovelock, Linxin Li, Michela Simoni, Sergei Gutnikov, Wilhelm Küker, Henry Ka Fung Mak, Peter M Rothwell
BACKGROUND AND PURPOSE: In patients with transient ischemic attack/ischemic stroke, microbleed burden predicts intracerebral hemorrhage (ICH), and ischemic stroke, but implications for antiplatelet treatment are uncertain. Previous cohort studies have had insufficient follow-up to assess the time course of risks, have not stratified risks by antithrombotic use, and have not reported extracranial bleeds or functional outcome of ICH versus ischemic stroke. METHODS: In 2 independent prospective cohorts with transient ischemic attack/ischemic stroke (Oxford Vascular Study/mainly white; University of Hong Kong/mainly Chinese), antiplatelet treatment was started routinely irrespective of microbleed burden...

INTRODUCTION: Laparoscopic hepatectomy is considered an acceptable treatment of choice in selected patients with primary hepatocellular carcinoma (HCC). Whether indocyanine green (ICG) immunofluorescence, a new technology, may improve surgery outcomes has yet to be tested. The aim of the present study was to investigate and compare the effect of ICG fluorescence imaging on the outcomes of pure laparoscopic hepatectomy and open hepatectomy for primary HCC with background cirrhosis. METHODS: From January 2015 to June 2016, 20 patients with HCC and liver cirrhosis underwent laparoscopic hepatectomy with ICG immunofluorescence...

The efficacy of S-omeprazole as proton pump inhibitor compared to its enantiomer R-omeprazole is studied using density functional theoretical calculations. The pharmacokinetic studies suggest that the efficacy of S-omeprazole presumably depends on metabolic pathway and excretion from the human body. The DFT calculations at SMDWater -B3LYP-D3/6-311+G(d,p)/LANL2DZ//B3LYP/6-31G(d)/LANL2DZ with triradicaloid model active species, [Por•+ FeIV (SH)O], of the CYP2C19 enzyme with high spin quartet and low spin doublet states demonstrate C-H bond activation mechanism through a two-state rebound process for hydroxylation of R-omeprazole and S-omeprazole...
