BACKGROUND: Optimal surgical treatment of infective tricuspid endocarditis is debatable, especially in the setting of inherent social and pathologic concerns. This study seeks to compare tricuspid valve repair, replacement, and excision for the treatment of infective endocarditis METHODS: A single center cardiac surgery database was queried between 2012 and 2016 to identify patients >18 years who underwent tricuspid valve surgery for infective endocarditis. Patients were divided into 3 groups based on the type of tricuspid valve surgery: valvectomy, repair, or replacement and evaluated to identify differences between the pre-op factors and outcomes including mortality, length of stay, and complications...

BACKGROUND: A large body of research has investigated the rise of injection drug use and HIV transmission in Tijuana and Ciudad Juarez (CJ). However, little is known about the dynamics of injecting in Hermosillo. This study compares drug-related behaviors and risk environment for HIV of people who inject drugs (PWID) across Tijuana, CJ, and Hermosillo to identify factors that could explain differences in HIV prevalence. METHODS: Data from Tijuana belong to a prospective study (El Cuete IV)...

Modulation of the inflammatory microenvironment after stroke opens a new avenue for the development of novel neurorestorative therapies in stroke. Understanding the spatio-temporal profile of (neuro-)inflammatory imaging biomarkers in detail thereby represents a crucial factor in the development and application of immunomodulatory therapies. The early integration of quantitative molecular imaging biomarkers in stroke drug development may provide key information about (i) early diagnosis and follow-up, (ii) spatio-temporal drug-target engagement (pharmacodynamic biomarker), (iii) differentiation of responders and non-responders in the patient cohort (inclusion/exclusion criteria; predictive biomarkers), and (iv) the mechanism of action...

The large number of drugs administered simultaneously to neonates and children in hospital results in the formation of particles that are potentially infused. We have investigated the ability of IV in-line filters to eliminate particulate matter from multidrug infusion lines and so prevent contamination. The impact on particle occurrence of the internal volume of the IV line below the in-line filter was then evaluated. The multidrug therapy given to children was reproduced with and without in-line filtration...

Nephrotoxicity is a serious side effect for the immunosuppressant drug cyclosporine (CSA). In this study, we tested the hypothesis that administration of calcium channel blockers such as verapamil or nifedipine ameliorate renal CSA-induced renal dysfunction. Furthermore, our study investigates the roles of inflammatory, oxidative, and fibrotic pathways in CSA-induced renal dysfunction. Six groups of male rats (n=6/group) were used and received one of the following treatments for 7 consecutive days: vehicle (cremophor EL, i...

In this study, fifteenth new 2,5-disubstituted analgouges of phthalimide were designed and synthesized using the appropriate synthetic route to evaluate anticonvulsant activity against the maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) compare to phenytoin as a positive control. The structures of the synthesized compounds were confirmed by FT-IR, H-NMR, C-NMR and MASS spectroscopy. All the tested compounds were found to be effective in the PTZ model at the dose of 60 mg/kg and most of the compounds showed protection against MES test indicative of their ability to inhibit the seizure spread at the all dose ranges...

Children and adults with frequent and severe episodes of epilepsy that do not respond to standard treatments (such as carbamazepine, phenytoin and valproate) have long been prescribed cannabidiol (CBD) as an anticonvulsant drug. However, the safety of its chronic use in relation to reproduction has not been fully examined. This study aimed to assess the effects of chronic CBD exposure on the male reproductive system. CBD was orally administered to 21-day-old male Swiss mice at doses of 15 and 30 mg kg-1 daily (CBD 15 and 30 groups, respectively), with a control group receiving sunflower oil, for 34 consecutive days...

BACKGROUND AND AIM: The synthetic drug fenoldopam mesylate (FM) may have a renoprotective role, and a "renal dose" of 0.1 µg/kg/min intravenous (IV) infusion of FM has been reported as able to increase renal blood flow without affecting systemic blood pressure. But conclusive data are still lacking. We aimed to investigate by color-Doppler ultrasonography the effects of IV administration of FM at this dosage in hypertensive chronic kidney disease (CKD) patients, and verify whether it may induce any systemic hemodynamic alteration...

With the aim to obtain dual acting drugs able to target both nuclear DNA and mitochondria, Pt(iv) kiteplatin derivatives having dichloroacetate (DCA) ligands in axial positions have been synthesized. The rather fast hydrolysis (t1/2 of ca. 1 h) and reduction (by ascorbic acid) of these Pt(iv) derivatives did not impede a potent pharmacological effect on tumor cells. Moreover, similarly to kiteplatin, also the Pt(iv)-DCA compounds proved to be capable of overcoming oxaliplatin-resistance, which is particularly important in view of the fact that metastatic colorectal cancer is the third most common cancer in males and the second in females...

Background: Care of patients with trauma is not only limited to the sustained physical injuries but also requires addressing social issues, such as substance abuse and interpersonal violence, which are responsible for trauma-related recidivism. This study investigates whether there are age-related variations in these problematic social behaviors to analyze whether there is an age cut-off at which point adolescents should be screened for adult social behaviors. Methods: Retrospective review of patients with trauma aged 12-21 admitted to an urban Level 1 adult and pediatric trauma center between February 2013 and April 2016...

Linear IgA bullous dermatosis (LABD) is an autoimmune blistering rash caused by IgA autoantibodies against the epidermal basement membrane zone. It commonly is drug induced, often in association with systemic vancomycin. We report a case of a previously healthy 77-year-old man who developed a diffuse macular rash and hemorrhagic bullae on the left leg 10 days after placement of a vancomycin-impregnated cement spacer (VICS) during a revision knee arthroplasty and initiation of postoperative treatment with intravenous (IV) vancomycin...

OBJECTIVE: An estimated 336 per 100 000 people in Russia are infected with hepatitis C virus, including up to 75% with genotype (GT) 1b. In the TURQUOISE-II/-III trials, a 12-week regimen of the direct-acting antiviral agents ombitasvir (OBV), paritaprevir (PTV), ritonavir, and dasabuvir (DSV) in GT1b-infected patients with compensated cirrhosis resulted in 12-week sustained virologic response (SVR) rates of 100%. PATIENTS AND METHODS: In TURQUOISE-IV, GT1b-infected patients (n=36) from Russia and Belarus with compensated cirrhosis, who were treatment naive or previously treated with pegylated interferon/ribavirin (RBV), received OBV/PTV/ritonavir+DSV+RBV for 12 weeks...

BACKGROUND: Antidepressants are a first-line treatment for adults with moderate to severe major depression. However, many people prescribed antidepressants for depression don't respond fully to such medication, and little evidence is available to inform the most appropriate 'next step' treatment for such patients, who may be referred to as having treatment-resistant depression (TRD). National Institute for Health and Care Excellence (NICE) guidance suggests that the 'next step' for those who do not respond to antidepressants may include a change in the dose or type of antidepressant medication, the addition of another medication, or the start of psychotherapy...

BACKGROUND: Immune checkpoint inhibitors (ICIs) are a promising class of anticancer drugs associated with immune-related adverse events (IRAEs). In registration studies of selected cancer populations, neurologic IRAEs were rare. Post-marketing experience describing their prevalence in clinical practice continues to be reported. METHODS: A retrospective cohort of patients treated at our institution with ICIs from 2005 to 2017 was identified. Patients with new neurologic ICD codes documented during or after ICI treatment were enrolled...

Lung cancer is the most common cancer worldwide and the most common cause of cancer-related death. Non-small-cell lung cancer comprises ~87% of newly diagnosed cases of lung cancer, and nearly one-third of these patients have stage III disease. Despite improvements in the treatment of stage IV lung cancer, particularly with the introduction and dissemination of checkpoint inhibitors, very little progress has been made in the treatment of stage III lung cancer. In this article, we discuss the general staging criteria and treatment options for stage III lung cancer...

The opportunistic Gram-negative pathogen Pseudomonas aeruginosa , known for its intrinsic and acquired antibiotic resistance, has a notorious ability to form biofilms, which often facilitate chronic infections. The evolutionary paths to antibiotic resistance have mainly been investigated in planktonic cultures and are less studied in biofilms. We experimentally evolved P. aeruginosa PAO1 colony-biofilms and stationary-phase planktonic cultures for seven passages in the presence of sub-inhibitory levels (0.1 mg/L) of ciprofloxacin (CIP) and performed a genotypic (whole bacterial population sequencing) and phenotypic assessment of the populations...
