Modeling of Hexavalent Chromium Removal with Hydrophobically Modified Cellulose Nanofibers.

Cellulose nanofibers (CNF) are sustainable nanomaterials, obtained by the mechanical disintegration of cellulose, whose properties make them an interesting adsorbent material due to their high specific area and active groups. CNF are easily functionalized to optimize the performance for different uses. The hypothesis of this work is that hydrophobization can be used to improve their ability as adsorbents.

Factors associated with in-hospital mortality and adverse outcomes during the vulnerable post-discharge phase after the first episode of acute heart failure: results of the NOVICA-2 study.

Objective: To identify patients at risk of in-hospital mortality and adverse outcomes during the vulnerable post-discharge period after the first acute heart failure episode (de novo AHF) attended at the emergency department.

Methods: This is a secondary review of de novo AHF patients included in the prospective, multicentre EAHFE (Epidemiology of Acute Heart Failure in Emergency Department) Registry. We included consecutive patients with de novo AHF, for whom 29 independent variables were recorded.

Treatment of Bisphosphonate-Related Osteonecrosis of the Jaw With Plasma Rich in Growth Factors After Dental Implant Surgery: A Case Report.

Oral bisphosphonates are commonly used to improve bone density in patients who suffer from a variety of pathologies. However, they have also been known to cause bisphosphonate-related osteonecrosis of the jaws (BRONJ). The aim of this clinical case presentation is to (1) determine whether the currently recommended length of time that oral bisphosphonates should be discontinued, before performing dental implant surgery, is sufficient to prevent BRONJ and (2) to describe an alternative treatment for BRONJ.

Diagnostic Accuracy of the FIGO and the 5-Tier Fetal Heart Rate Classification Systems in the Detection of Neonatal Acidemia.

 The objective of this study was to determine ability to detect neonatal acidemia and interobserver agreement with the FIGO 3-tier and 5-tier fetal heart rate (FHR) classification systems.  This was a case-control study.  This study was set at the University Medical Center.

Spontaneous uterine rupture caused by placenta percreta at 18 weeks' gestation after in vitro fertilization.

We report a case of spontaneous uterine rupture caused by placenta percreta at 18 weeks' gestation after in vitro fertilization. Spontaneous uterine rupture is an extremely infrequent obstetric complication that may compromise the lives of the fetus and the mother. We describe the case of a pregnant woman at 18 weeks' gestation who presented with sudden abdominal pain and severe hemoperitoneum.
