Renin-angiotensin system as an important regulator of renal function has also a major role in inflammation. In the present study, the effects of captopril on renal dysfunction, renal cytokine levels, and renal tissue oxidative damage were investigated in lipopolysaccharide (LPS)-induced inflammation model in rats. Treatment of five groups of the rats was carried out as follows (1) saline as a control, (2) LPS 1 mg/kg, and (3-5) 10, 50, or 100 mg/kg captopril 30 min, respectively, before LPS. The treatments were given for 12 days. Finally, the animals were deeply anesthetized, the blood samples were obtained, and the renal tissues were removed and kept for biochemical measurements. Administration of LPS increased serum blood urea nitrogen and creatinine (P less then 0.001). Pretreatment with all doses of captopril decreased these parameters (P less then 0.001). LPS also increased interleukin-6 (IL-6), malondialdehyde, and nitric oxide metabolites in the renal tissues (P less then 0.05 - P less then 0.001), which was prevented by captopril (P less then 0.05 - P less then 0.001). The total thiol concentration and superoxide dismutase and catalase activities in the kidney of the LPS group were lower than the control (P less then 0.001), while they were enhanced when the animals were cotreated by captopril (P less then 0.01 - P less then 0.001). The results of the present study showed that captopril improved renal function and attenuated tissue oxidative stress in LPS-induced inflammation model in rats.The worldwide prevalence of noncommunicable diseases (NCDs) is projected to increase substantially over the next few decades. Chronic kidney disease (CKD) is a key determinant of poor health outcomes for major NCD. Genetic predisposition and environmental exposures are contributory factors, but increasingly, it is being recognized that fetal development is also an important modulator of the NCD risk. Low birth weight (LBW) and CKD affect more disadvantaged populations and ethnic minorities and, therefore, causes a disproportionate burden on the poor. Human nephron number is highly variable and may range from under half a million to almost over two million. Significant variability is already present at birth, highlighting the importance of early nephrogenesis. Nearly 60% of nephrons are developed in the third-trimester of pregnancy. Nephron numbers increase in proportion to birth weight and gestational age. This wide-variability probably contributes to individual susceptibility to develop CKD where individualsof intensified life-long surveillance of LBW people, anticipating this risk.A new-onset acute kidney injury (AKI) after arthroplasty impairs rehabilitation and outcome. A prior knowledge of risk factors contributes to a planned preventive management and prognostication. Although many studies have addressed the issue, our objective was to perform a meta-analysis to bring a consensus on the perioperative risk factors promoting AKI postoperatively. We conducted a systematic review and meta-analysis of observational studies reporting risk factors with odds of development of AKI according to the existing criteria after hip or knee replacement surgery. We searched the PubMed and Google Scholar databases for free English articles published until June 2018. selleck chemicals Two authors independently screened the articles and extracted data. Discrepancies were resolved by consensus or consulting the third author. Methodological quality of the articles was assessed using the Newcastle-Ottawa Scale. A total of five studies were included in this meta-analysis. The following risk factors were found to contribute to new kidney injury advanced age; male gender; preoperative liver, cardiac, or kidney diseases; presence of heart failure; American Society of Anesthesiologists grade ≥ 3; requirement of perioperative blood transfusion, revision arthroplasty, and knee arthroplasty; body mass index; and use of angiotensin-converting enzyme inhibitors. Diabetes, hypertension, duration of surgery, type of anesthesia, and preoperative serum creatinine were not found to be associated with renal injury. The key limitation was the availability of small number of studies. More longitudinal observational studies addressing the issue are the need of the hour, and, till then, a preventive strategy aimed at the identified risk factors should help.

EUS has been shown in two small series to be capable of documenting increases in the total esophageal wall thickness (TWT) in children and adults with eosinophilic esophagitis (EoE). To apply EUS-derived TWT in clinical situations or in scientific investigations in pediatric EoE, measurements of esophageal TWT in children of differing ages and heights are required.

Thirty patients (18M 12F, 7 months to 20 years and 10 months) with a history of esophageal symptoms, but no endoscopic or histologic criteria of EoE were studied using a through the scope 20 MHZ Olympus Ultrasound miniprobe UM-3R (Olympus America, Center Valley Pa 18034) through a GIF Q180 or 160 (Olympus) standard pediatric upper endoscope. The mucosa, the mucosa plus submucosa, and the TWT were measured in the mid- and distal esophagus immediately before taking diagnostic biopsies.

Measurements from both sites showed a statistically significant increase in TWT as a function of age (P < 0.001) and height (P < 0.001), as did the individual layers. The width of the mucosa and the submucosa were equivalent and together, they contributed more than half of the entire TWT. There were no significant differences between the means of the mid- and distal esophageal measurements. A multiple regression equation that can predict TWT based on age, with 95% confidence limits, is presented.

EUS has demonstrated that esophageal TWT in a cohort of control children correlates with height and with age and has provided insights into the organization of the esophageal wall. Esophageal TWT values obtained by EUS can now be interpreted to recognize esophageal wall thickening throughout childhood.
