Decades of research into the topic of oral nanoparticle (NP) delivery has still not provided a clear consensus regarding which properties produce an effective oral drug delivery system. The surface properties-charge and bioadhesiveness-as well as in vitro and in vivo correlation seem to generate the greatest number of disagreements within the field. Herein, a mechanism underlying the in vivo behavior of NPs is proposed, which bridges the gaps between these disagreements.

PubMed/MEDLINE and Embase-Ovid were searched on March 5, 2020, for English-language articles reporting survival for salvage surgery and nonsurgical management of recurrent HNSCC. Meta-analysis of HR estimates using random effects model was performed.

We aimed to characterize endoscopist recommendations regarding surveillance colonoscopy in older adults and identify patient, procedure, and endoscopist characteristics associated with recommendations to stop.

Objective: This systematic review assessed the prevalence and associated mortality impact of HIVseropositivity among injured patients in LMIC.
Methods: A systematic search of PubMed, EMBASE, Global Health, CINAHL, POPLINE and Cochrane databases through August 2016 was performed.
Background: The 2014-15 Ebola virus disease (EVD) epidemic strained health systems in west Africa already overburdened with other diseases, including malaria. Because EVD and malaria can be difficult to distinguish clinically, and rapid testing was not available in many Ebola Treatment Units (ETUs), guidelines recommended empirical malaria treatment. Little is known, however, about the prevalence and characteristics of patients entering an ETU who were infected with malaria parasites, either alone or concurrently with Ebola virus.

The Dehydration: Assessing Kids Accurately (DHAKA) score was derived for assessing dehydration in children with diarrhoea in a low-income country setting. In this study, we aimed to externally validate the DHAKA score in a new population of children and compare its accuracy and reliability to the current Integrated Management of Childhood Illness (IMCI) algorithm.

Objective: To assess the accuracy of point-of-care ultrasound measurement of the aorta-to-IVC ratio as a predictor of dehydration in children.
Methods: A prospective cohort study of children under five years with acute diarrhea was conducted in the rehydration unit of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b).
Introduction: Diarrhea remains one of the most common and most deadly conditions affecting children worldwide. Accurately assessing dehydration status is critical to determining treatment course, yet no clinical diagnostic models for dehydration have been empirically derived and validated for use in resource-limited settings.
Methods: In the Dehydration: Assessing Kids Accurately (DHAKA) prospective cohort study, a random sample of children under 5 with acute diarrhea was enrolled between February and June 2014 in Bangladesh.
