Coagulation removal of dissolved organic matter (DOM) in nanofiltration concentrate of biologically treated landfill leachate by ZrCl: Performance, mechanism and coagulant recycling.

Coagulation treatment is often applied for removing the residual refractory dissolved organic matter (DOM) in biologically treated landfill leachate nanofiltration concentrate (LLNC) before discharge or further desalination treatment. However, the DOM removal efficiency by traditional coagulant needs to be improved, and two problems including the coagulant loss and difficulty in disposal of coagulation sludge need to be resolved. Based on this practical demand, a new coagulant ZrCl was adopted for LLNC treatment for the first time.

Wait times for endoscopic sinus surgery influence patient-reported outcome measures in patients with chronic rhinosinusitis who fulfill appropriateness criteria.

Background: Previous studies on the impact of wait times for endoscopic sinus surgery (ESS) in medically recalcitrant chronic rhinosinusitis (rCRS) have not examined its influence on the 5 distinct symptoms domains of the 22-item Sino-Nasal Outcome Test (SNOT-22), and have not applied evidence-based surgical indications. Our primary study objective was to investigate the impact of ESS wait times on postoperative SNOT-22 global and symptom domain scores in patients with rCRS deemed "appropriate" surgical candidates.

Methods: This was a retrospective analysis of adult patients with rCRS undergoing ESS, categorized as "appropriate" surgical candidates.

Analysis of health-related quality-of-life outcomes and their predictive factors in pediatric patients who undergo otoplasty.

Background: There are limited data on the effect of otoplasty on health-related quality of life in children with prominent ears. Predictors of health-related quality-of-life outcomes in otoplasty have not been well studied.

Methods: In this retrospective cohort study, 79 patients aged 18 years and younger who underwent otoplasty, and their parents, were asked to complete a survey, which included the Glasgow Children's Benefit Inventory and the Pediatric Quality of Life Inventory, to assess the parent-reported health-related quality-of-life changes and the current health-related quality of life, respectively.

The effect of tongue-tie division on breastfeeding and speech articulation: a systematic review.

Objective: To systematically review the outcomes of tongue-tie division procedures in patients with ankyloglossia with the goal of (1) deriving clinically oriented insights into the effect of tongue-tie division procedures and (2) identifying needs in knowledge to stimulate further research.

Data Sources: Medline, EMBASE, and Cochrane databases were searched without any limitations, for studies published between 1966 and June 2012.

Review Methods: Studies were included (level 4 evidence or above) if subjects of any age had ankyloglossia and underwent tongue-tie release.
