BACKGROUND: It is assumed that recreational use of methamphetamine can trigger acute myocardial infarction (AMI) events, but estimates of longitudinal hazards of AMI among methamphetamine users are lacking. METHODS: Retrospective cohort study: Competing-risks analysis was used to estimate time-to-AMI patterns in methamphetamine versus matched appendicitis (population-proxy) and matched cocaine (drug-control) groups. Cohorts were propensity-score-matched using demographic and clinical variables...

AIMS: To examine the incidence, risk factors and clinical outcomes of hyperkalaemia in people with diabetes in a real-world setting. METHODS: Using Danish health registries, we identified a population-based cohort of people with first-time drug-treated diabetes, in the period 2000-2012. First, the cumulative incidence of hyperkalaemia, defined as first blood test with potassium level >5.0 mmol/l after diabetes treatment initiation, was ascertained. Second, in a case-control analysis, risk factors were compared in people with vs without hyperkalaemia...

Salmonella Typhimurium (including S.Typhimurium 1,4,[5],12:i-) and other enteric pathogens cause acute infection in pigs during the weaning stage, often evolving into chronic infections responsible for the introduction of zoonotic bacteria into the slaughterhouse and thus determining carcass contamination. In addition to being zoonotic hazards, these pathogens are responsible for economic losses in affected farms. Traditionally, antibiotic treatments have been largely administered in order to reduce the infection burden but it favored, as a direct consequence, an increase in the number of multi-drug resistance strains...

BACKGROUND: Dutasteride is a potent inhibitor of 5-alpha reductase enzymes that reduces concentrations of dihydrotestosterone to a greater extent than finasteride. Whether this has adverse implications for bone health is unknown. We compared the risk of osteoporosis and fractures in older men treated with dutasteride or finasteride. METHODS: We conducted a population-based retrospective cohort study with high-dimensional propensity score matching of Ontario men aged 66 years or older who started treatment with dutasteride or finasteride between January 1, 2006 and December 31, 2012...

A time-to-event (TTE) model has been developed to characterise a histopathology toxicity that can only be detected at the time of animal sacrifice. The model of choice was a hazard model with a Weibull distribution and dose was a significant covariate. The diagnostic plots showed a satisfactory fit of the data, despite the high degree of left- and right- censoring. Comparison to a probabilistic logit model shows similar performance in describing the data with a slight underestimation of survival by the Logit model...

Background/Aims: Autologous haematopoietic stem cell transplantation (AHSCT) is a therapeutic option for patients with severe, treatment-refractory Crohn's disease (CD). The evidence base for AHSCT for CD is limited, with one randomised trial (ASTIC) suggesting benefit. The aim of this study was to evaluate safety and efficacy for patients undergoing AHSCT for CD in Europe outside the ASTIC trial. Methods: We identified 99 patients in the European Society for Blood and Marrow Transplantation (EBMT) registry who were eligible for inclusion...

Background: older patients are commonly believed to derive less benefit from cancer drugs, even if they fulfil clinical trial eligibility [Talarico et al. (2004, J Clin Oncol, 22(22):4626-31)]. We aim to examine if novel oncology drugs provide differential age-based treatment outcomes for patients on clinical trials. Methods: a systematic review of randomised control trials (RCTs) cited for clinical efficacy evidence in novel oncology drug approvals by the Food and Drug Administration, European Medicines Agency and Health Canada between 2006 and 2017 was conducted...

Since nitroaromatic and nitramine type energetic materials, mostly arising from military activities, are persistent pollutants in soil and groundwater, on-site sensing of these hazardous chemicals has gained importance. A novel electrochemical sensor was designed for detecting nitroaromatic and nitramine type energetic materials, relying on gold nanoparticles (Aunano ) -modified glassy carbon (GC) electrode coated with nitro-energetic memory poly(carbazole-aniline) copolymer (Cz- co-ANI) film (e.g., TNT memory-GC/P(Cz- co-ANI)-Aunano modified electrode)...

Multidrug-resistant bacterial infections are being increasingly treated in clinics with polymyxins, a class of antibiotics associated with adverse effects in the kidney, nervous system, or airways of a significant proportion of human and animal patients. Although many of the resistant pathogens display enhanced virulence, a hazard of cytotoxic interactions between polymyxin antibiotics and bacterial virulence factors (VFs) has not been assessed, to date. We report here on testing paired combinations of four Pseudomonas aeruginosa VF phenazine toxins, pyocyanin (PYO), 1-hydroxyphenazine (1-HP), phenazine-1-carboxylic acid (PCA), phenazine-1-carboxamide (PCN), and two commonly prescribed polymyxin drugs, colistimethate (CMS)/colistin and polymyxin B, in three human airway cell lines, BEAS-2B, HBE-1, and CFT-1...

BACKGROUND: The right drug to the right patient at the right time is one of the ideals of Individualized Medicine (IM) and remains one of the most compelling promises of the post-genomic age. The addition of genomic information is expected to increase the precision of an individual patient's treatment, resulting in improved outcomes. While pilot studies have been encouraging, key aspects of interpreting tumor genomics information, such as somatic activation of drug transport or metabolism, have not been systematically evaluated...

Caco-2 cells are a commonly used model for estimating the intestinal bioavailability of single chemical entity pharmaceuticals. Caco-2 cells, when induced with calcitriol, also express other biological functions such as phase I (CYP) and phase II (glucuronosyltransferases) drug metabolizing enzymes which are relevant to drug-supplement interactions. Intestinal bioavailability is an important factor in the overall safety assessment of products consumed orally. Foods, including herbal dietary supplements, are complex substances with multiple chemical components...

Renal cell carcinoma (RCC) is the most common malignancy of kidney and remains largely intractable once it recurs after resection. mTOR inhibitors have been one of the mainstays used against recurrent RCC; however, there has been a major problem of the resistance to mTOR inhibitors, and thus new combination treatments with mTOR inhibitors are required. We here retrospectively showed that regular use of antilipidemic drug statins could provide a longer progression free survival (PFS) in RCC patients prescribed with an mTOR inhibitor everolimus than without statins (median PFS, 7...

BACKGROUND: Previous studies have shown that uremia patients under hemodialysis (HD) have a significantly higher occurrence of peptic ulcer bleeding (PUB) than healthy controls and that elderly patients remain at high risk of peptic ulcer disease (PUD) and PUB. Here we aimed to identify the risk factors for PUB in aging (≥65-years-old) uremic patients under regular HD. METHODS: Using data from the National Health Insurance Research Database of Taiwan, we compared 18,252 aging regular HD patients and 17,883 age-, gender-, and medication-matched patients without kidney disease (control group)...
