Pesticides are active substances with potentially adverse effects on human health, and therefore great effort is addressed to study the relation between their widespread use and the effects on humans. To track human exposure to pesticides, novel approaches are needed to give additional information on exposure at population level. In this study, a novel application of Wastewater-Based Epidemiology (WBE) was developed to measure the intake of pyrethroid pesticides in a population. Three human urinary metabolites of pyrethroids were selected and validated as biomarkers of exposure by evaluating their sources and stability in wastewater...

BACKGROUND: As the cost of health-care delivery rises in the era of bundled payments for care, there is an impetus toward minimizing hospitalization. Evidence to support the safety of open reduction and internal fixation (ORIF) of ankle fractures in the outpatient setting is largely anecdotal. METHODS: Patients who underwent ORIF from 2005 to 2013 were identified via postoperative diagnoses of ankle fracture and Current Procedural Terminology codes; patients with open fractures and patients who were emergency cases were excluded...

BACKGROUND: Neopterin is an unconjugated pteridine that is secreted in large quantities by activated macrophages and can be used as a clinical marker of activated cellular immunity and oxidative stress. We aimed to investigate whether urinary neopterin levels are associated with cognitive function in people with Down syndrome (DS). METHODS: Out of 32 adults with DS who originally participated in a longitudinal study, 25 were followed up at 4 years. Informants rated their adaptive behavior (ABAS) and the adults with DS attempted assessments of language skills and memory at both baseline and follow-up time points (Modified Memory Object Task, MOMT), and receptive vocabulary (British Picture Vocabulary Scale, BPVS)...

Urinary extracellular vesicles (EVs) are a promising source of biomarkers, which can be obtained in a non-invasive manner. However, the yield of EVs from urine samples may be insufficient for various analyses due to the entrapment of EVs by the Tamm-Horsfall protein (THP) meshwork. Here, we developed a simple dilution protocol to increase the urinary EV yield by disrupting the interaction between THP filaments and EVs with the help of alkaline pH and lowered ionic concentration. The integrity of the EVs and THP was assessed by electron microscopy...

BACKGROUND: Growth hormone (GH) has many direct and indirect actions and roles including substrate regulation and priming of some cells of the immune system, and the expected aspects of growth and repair. Different concentrations in human body fluids reflect the exercise-induced growth hormone response (EIGR) after exercise. In populations such as elite athletes, the invasive nature of venous sampling is poorly accepted. Thus, this study examines possible viable alternatives such as urine and saliva samples and the GH concentration...

Leptospirosis is a zoonotic disease whose severe forms are often accompanied by kidney dysfunction. In the present study, urinary markers were studied for potential prediction of disease severity. Urine samples from 135 patients with or without leptospirosis at San Lazaro Hospital, the Philippines, were analyzed. Urine levels of defensin α1 (uDA1) were compared with those of neutrophil gelatinase-associated lipocalin (uNGAL) and N-acetyl-β-d-glucosidase (uNAG). Serum creatinine (Cr) was used as a marker of kidney injury...

PURPOSE: Enhanced recovery after surgery (ERAS) pathways are standard practice in adult specialties resulting in improved outcomes. It is unclear whether ERAS principles are applicable to Paediatric Surgery. We performed a scoping review to identify the extent to which ERAS has been used in Paediatric Surgery, the nature of interventions, and outcomes. METHODS: Pubmed, Cochrane library, Google Scholar, and Embase were searched using the terms enhanced recovery, post-operative protocol/pathway, fast track surgery, and paediatric surgery...

The aim of this review is to present the available radiobiological, technical and clinical data about extreme hypofractionation in primary prostate cancer radiotherapy. The interest in this technique is based on the favourable radiobiological characteristics of prostate cancer and supported by advantageous logistic aspects deriving from short overall treatment time. The clinical validity of short-term treatment schedule is proven by a body of non-randomised studies, using both isocentric (LINAC-based) or non-isocentric (CyberKnife(®)-based) stereotactic body irradiation techniques...

Urological and surgical treatment of urinary stones are highly technological and technology-driven disciplines in present-day surgery. German medical engineering has always been recognized for its technical innovations in endoscopic surgery. Current and future trends are indicative of further miniaturization and automation of surgical instruments and assist systems to facilitate endourological procedures as well as improvements in the quality of results and ergonomics. These technologies include, e. g. 3D-tracking to facilitate access to the pelvicaliceal system for percutaneous nephrolithotomy (PNL) or robotic master-slave systems for endourology...

CONTEXT: Bladder cancer is the cause of more than 150,000 deaths per year. The overall rate of survival is approximately 45%, with a 10-year recurrence-free rate of 50-59%, with no changes in the last decade. OBJECTIVE: Due to a lack of agreement on the follow-up of cystectomy or on a uniform treatment when faced with the various types of recurrence, we have analysed the most recent literature in an attempt to unify the criteria for the diagnosis and treatment of bladder cancer...

The existence of a glucuronide conjugate of the major circulating clopidogrel metabolites, called clopidogrel acyl glucuronide (CAG), is already known. However, information regarding its pharmacokinetics (PK), metabolism, and clearance are modest. We investigated in vivo the potential CAG trans-esterification to clopidogrel (reaction occurring in vitro in particular conditions) by administering the metabolite to mice. Experiments were then carried out on men, clopidogrel administered alone or followed by activated charcoal intake (intestinal reabsorption blockade)...
