Influence of Single Stent Size and Tandem Stents Subject to Extrinsic Ureteral Obstruction and Stent Occlusion on Stent Failure.

J Endourol 2021 Jul 27. Epub 2021 Jul 27.

Weizmann Institute of Science, 34976, Earth and Planetary Sciences, Herzl Street 234, Rehovot, Israel, 7610001;

Drainage of obstructed kidney due to extrinsic ureteral obstruction (EUO), required to prevent renal damage, is often achieved using double-J ureteral stents. But these stents fail frequently, and there is considerable debate regarding what stent size, type and configuration offer the best option for sustained drainage. Here, we examine the impact of stent diameter and choice of single/tandem configuration, subject to EUO and various degrees of stent occlusion, on stent failure. Read More

Arterial hypertension as an inaugural sign of myomatous uterus.

BMJ Case Rep 2021 Jul 20;14(7). Epub 2021 Jul 20.

Department of Gynecology, Centro Hospitalar e Universitario de Coimbra EPE, Coimbra, Portugal.

Uterine fibroids can be large enough to cause mechanical obstruction of pelvic ureters, which may result in hydroureters and hydronephrosis. Renal impairment frequently results in hypertension due to increased activity of the tubuloglomerular feedback system and renin-angiotensin-aldosterone axis. This process, however, seems reversible because normalisation of blood pressure is possible after the relief of renal obstruction. Read More

Influence of the subsurface physical barrier on nitrate contamination and seawater intrusion in an unconfined aquifer.

Environ Pollut 2021 Sep 4;284:117528. Epub 2021 Jun 4.

Key Laboratory of Marine Environment and Ecological Education, Ocean University of China, Qingdao, 266100, China.

Coastal areas are facing not only environmental problems associated with seawater intrusion (SWI) but also health and ecological problems caused by excessive nitrate (NO) contamination. The installation of a subsurface physical barrier (SPB) is one of the common methods employed to reduce or prevent SWI, but there are few studies on the impact of SPBs on NP in groundwater. Through laboratory experiments and numerical simulations, the effects of the hydraulic gradient (HG), the nitrate concentration of the set groundwater nitrate pollution source, the relative height of the SPB (H') and the relative distance between the SPB and the saltwater boundary on the NP of groundwater in the presence of SWI, subsurface dams and cut-off walls were studied.

Household Food Insecurity, Lung Function, and COPD in US Adults.

Nutrients 2021 Jun 19;13(6). Epub 2021 Jun 19.

Program in Human Nutrition, Department of International Health, The Johns Hopkins Bloomberg School of Public Health, Baltimore, MD 21205, USA.

Increasing epidemiological evidence suggests that optimal diet quality helps to improve preservation of lung function and to reduce chronic obstructive pulmonary disease (COPD) risk, but no study has investigated the association of food insecurity (FI) and lung health in the general population. Using data from a representative sample of US adults who participated in the National Health and Nutrition Examination Survey (NHANES) 2007-2012 cycles, we investigated the association between FI with lung function and spirometrically defined COPD in 12,469 individuals aged ≥ 18 years of age. FI (high vs. Read More
