Difficult Patient Behavior in Dialysis Facilities.

Blood Purif 2018 Dec 6:1-5. Epub 2018 Dec 6.

Difficult behavior exhibited by dialysis patients is a spectrum that includes nonadherence, verbal or physical abuse, and threatening acts. Such behaviors may lead to harmful consequences to the patient, other patients, the facility, and staff and can culminate in involuntary discharge. It is important to recognize that these "difficult behaviors" may be due to underlying psychosocial or medical issues, which places an onus on care providers to explore further. Read More

The innate immune system is the first line of defense against pathogenic threats. For the early pathogen recognition and activation of cell protective mechanisms, germline-encoded pattern recognition receptors (PRRs) detect characteristic and evolutionary conserved pathogen-associated molecular patterns (PAMPs). PRRs are therefore key elements in the innate immune response; in addition, they sense danger-associated molecular patterns (DAMPs) that are released by host cell molecules under pathophysiological conditions.

This study presents the first investigation of concentrations and congener group patterns of short- and medium-chain chlorinated paraffins (SCCPs and MCCPs) in 159 dust samples from plastic sports courts and synthetic turf in Beijing, China. The geometric mean concentration of SCCPs and MCCPs in dusts from plastic tracks (5429 and 15157 μg g-1) and basketball courts (5139 and 11878 μg g-1) were significantly higher than those from plastic tennis courts, badminton courts, and synthetic turf, meanwhile they were 1-3 orders of magnitude higher than those in dusts from other indoor environments. The friction between sneaker soles and plastic track materials may lead to the wear and decomposition of rubber, which may be an important source of chlorinated paraffins (CPs) in the dust from plastic tracks.

Objectives: Longitudinal data on the course and relationship of concurrent psychopathology in youth are scarce but are of need for better practical patient care and prevention. This study explores the course of (and relationships over time) between sleep problems and concurrent dimensional difficulties relating to anxiety/depression, attention deficiency and aggressive behaviors in childhood and adolescence. The latter three may jointly form a broad syndrome, the dysregulation profile. Read More

Importance: The 2013/2014 American Society of Clinical Oncology and College of American Pathologists (ASCO-CAP) guidelines for HER2 testing by fluorescence in situ hybridization (FISH) designated an "equivocal" category (average HER2 copies per tumor cell ≥4-6 with HER2/CEP17 ratio <2.0) to be resolved as negative or positive by assessments with alternative control probes. Approximately 4% to 12% of all invasive breast cancers are characterized as HER2-equivocal based on FISH. Read More

Revisiting the strong stretching theory for pH-responsive polyelectrolyte brushes: effects of consideration of excluded volume interactions and an expanded form of the mass action law.

In this paper, we develop a theory to account for the effect of excluded volume (EV) interactions in the strong stretching theory (SST) based description of pH-responsive polyelectrolyte (PE) brushes. The existing studies have considered the PE brushes to be present in a θ-solvent and hence have neglected the EV interactions; however, such a consideration cannot describe the situations where the pH-responsive brushes are in a "good" solvent. Secondly, we consider a more expanded form of the mass action law, governing the pH-dependent ionization of the PE molecules, in the SST description of the PE brushes. Read More
