Gentamicin induced acute renal damage and its evaluation using urinary biomarkers in rats.

Consistent, sensitive biomarkers of acute kidney injury in animal models and humans have historically represented a poorly met need for investigators and clinicians. Detection of early kidney damage using urinary biomarkers is essential to assess the adversity in preclinical toxicology studies, which will help in reducing attrition of lead candidates in drug development. This study was undertaken to evaluate recently identified urinary biomarkers use in identifying acute kidney injury compared to traditional serum markers in experimentally induced nephrotoxicity in male Sprague Dawley (SD) rats.

Global, Regional, and Country-Specific Lifetime Risks of Stroke, 1990 and 2016.

Background: The lifetime risk of stroke has been calculated in a limited number of selected populations. We sought to estimate the lifetime risk of stroke at the regional, country, and global level using data from a comprehensive study of the prevalence of major diseases.

Methods: We used the Global Burden of Disease (GBD) Study 2016 estimates of stroke incidence and the competing risks of death from any cause other than stroke to calculate the cumulative lifetime risks of first stroke, ischemic stroke, or hemorrhagic stroke among adults 25 years of age or older.

Predicting the risk of apparent treatment-resistant hypertension: a longitudinal, cohort study in an urban hypertension referral clinic.

Apparent treatment-resistant hypertension (aTRH) is associated with higher prevalence of secondary hypertension, greater risk for adverse pressure-related clinical outcomes, and influences diagnostic and therapeutic decision-making. We previously showed that cross-sectional prevalence estimates of aTRH are lower than its true prevalence as patients with uncontrolled hypertension undergoing intensification/optimization of therapy will, over time, increasingly satisfy diagnostic criteria for aTRH. aTRH was assessed in an urban referral hypertension clinic using a 140/90 mm Hg goal blood pressure target in 745 patients with uncontrolled blood pressure, who were predominately African-American (86%) and female (65%).

Ultrasound-guided percutaneous catheter drainage of various types of ruptured amebic liver abscess: a report of 117 cases from a highly endemic zone of India.

Objective: To determine the efficacy and safety ultrasound-guided percutaneous catheter drainage (US-PCD) in management of various types of ruptured amebic liver abscess including free rupture (FR) with diffuse intraperitoneal fluid collections (DIFC).

Methods: This study analyzed 117 patients with ruptured ALA who underwent US-PCD. The indication for US-PCD was failure to respond to conservative treatment and/or percutaneous needle aspiration.

Sex Bias in Interventional Clinical Trials.

Introduction: Prior studies have shown that sex bias exists with subject enrollment in clinical trials, with more men being enrolled than women. The objective of this study was to identify if sex bias continues to exist in present day clinical trials entered into ClinicalTrials.gov .

Science-based regulatory approach for safe nutraceuticals.

Food safety is a very complex issue. The food that reaches the plate from the farm is exposed to many hazards in processing methods and each of those steps is likely to contribute, indirectly or directly, to contaminants and pathogens that ultimately make the food unsafe. Consumers would always wish for 100% product safety; even regulators want to ensure 100% safety of the product and protect consumers.

Mangrove-Associated Fungi: A Novel Source of Potential Anticancer Compounds.

Cancer is the second leading cause of death worldwide, and the number of cases is increasing alarmingly every year. Current research focuses on the development of novel chemotherapeutic drugs derived from natural as well as synthetic sources. The abundance and diversity in natural resources offer tremendous potential for the discovery of novel molecules with unique mechanisms for cancer therapy.

Conducting Elevated Temperature Normal and Combined Pressure-Shear Plate Impact Experiments Via a Breech-end Sabot Heater System.

A novel approach for conducting normal and/or combined pressure-shear plate impact experiments at test temperatures up to 1000 °C is presented. The method enables elevated temperature plate-impact experiments aimed towards probing dynamic behavior of materials under thermomechanical extremes, while mitigating several special experimental challenges faced while performing similar experiments using the conventional plate impact approach. Custom adaptations are made to the breech-end of a single-stage gas-gun at Case Western Reserve University; these adaptations include a precision-machined extension piece made from SAE 4340 steel, which is strategically designed to mate the existing gun-barrel while providing a high tolerance match to the bore and keyway.

The Effectiveness of High-frequency Repetitive Transcranial Magnetic Stimulation in Persistent Somatoform Pain Disorder: A Case Series.

Somatoform pain disorders (SPD) are common, disabling and do not respond well to existing treatment modalities. We investigated the usefulness of 18 sessions of high frequency repetitive transcranial magnetic stimulation delivered at the left dorsolateral prefrontal cortex (DLPFC) in five right-handed patients with SPD. All patients reported significant improvement in pain relief and activities of daily living.

Postoperative endophthalmitis due to : First reported case of acute and virulent presentation from a tertiary eye care center in South India.

A 60-year-old male presented with pain and decreased vision 3 weeks following uneventful intracapsular cataract extraction with anterior vitrectomy for subluxated cataract. A diagnosis of acute endophthalmitis was made based on clinical and ultrasound features. Patient improved only after undergoing pars plana vitrectomies twice and repeated intravitreal antibiotic-steroid injections.

Endophytic Fungi: A Source of Potential Antifungal Compounds.

The emerging and reemerging forms of fungal infections encountered in the course of allogeneic bone marrow transplantations, cancer therapy, and organ transplants have necessitated the discovery of antifungal compounds with enhanced efficacy and better compatibility. A very limited number of antifungal compounds are in practice against the various forms of topical and systemic fungal infections. The trends of new antifungals being introduced into the market have remained insignificant while resistance towards the introduced drug has apparently increased, specifically in patients undergoing long-term treatment.

The objective of this study was to assess the genetic diversity of the Sirohi goat for and loci, and to study their association with antibody response induced by the Peste des petits ruminants (PPR) vaccine. A total of 360 Sirohi kids were studied using single stranded confirmation polymorphism (SSCP) followed by polymerase chain reaction sequence-based typing (PCR-SBT) for and diversities. The competitive enzyme-linked immuno-sorbent assay (C-ELISA) was used to evaluate immune response post-PPR vaccination.

Empyema Necessitans in the Setting of Methicillin-Susceptible Causing Pneumonia and Bacteremia.

Empyema necessitans (EN) is a rare phenomenon that refers to an insidious extension of the empyema through parietal pleura and subsequent dissection into subcutaneous tissue of the chest wall. A 29-year-old man presented to the hospital with fever and chills a few days after an inadvertent needle stick while injecting heroin. His left forearm was warm with an area of fluctuance.

Molecular Evidence of Genome Editing in a Mouse Model of Immunodeficiency.

Genome editing is the introduction of directed modifications in the genome, a process boosted to therapeutic levels by designer nucleases. Building on the experience of ex vivo gene therapy for severe combined immunodeficiencies, it is likely that genome editing of haematopoietic stem/progenitor cells (HSPC) for correction of inherited blood diseases will be an early clinical application. We show molecular evidence of gene correction in a mouse model of primary immunodeficiency.

The Transradial Approach for Lower Extremity Vascular Intervention.

Simultaneous technological advancements in both imaging as well as devices have resulted in an expansion of endovascular options for vascular access. In particular, radial access has traditionally been more favored for coronary interventions; its use in the aortoiliac and lower extremity vasculature has been constrained by the length of devices and the size of sheaths required. However, with increasing catheter shaft lengths, in addition to new thin-walled sheaths allowing for downsizing, the ability to perform transradial interventions on infrainguinal and infrageniculate vessels has been more readily facilitated.

Central nervous system histoplasmosis: Multicenter retrospective study on clinical features, diagnostic approach and outcome of treatment.

Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.

Marine Fungi: A Source of Potential Anticancer Compounds.

Metabolites from marine fungi have hogged the limelight in drug discovery because of their promise as therapeutic agents. A number of metabolites related to marine fungi have been discovered from various sources which are known to possess a range of activities as antibacterial, antiviral and anticancer agents. Although, over a thousand marine fungi based metabolites have already been reported, none of them have reached the market yet which could partly be related to non-comprehensive screening approaches and lack of sustained lead optimization.

Promoting deceased organ and tissue donation registration in family physician waiting rooms (RegisterNow-1 trial): study protocol for a pragmatic, stepped-wedge, cluster randomized controlled registry.

Background: There is a worldwide shortage of organs available for transplant, leading to preventable mortality associated with end-stage organ disease. While most citizens in many countries with an intent-to-donate "opt-in" system support organ donation, registration rates remain low. In Canada, most Canadians support organ donation but less than 25% in most provinces have registered their desire to donate their organs when they die.
