Older adults who take analgesics for chronic pain are at increased risk for adverse drug events (ADEs). The purpose of this descriptive pilot survey was to examine how older adults self-identify analgesic ADEs, and actions they take in response to analgesic ADEs. Twenty-two community dwelling older adults with chronic pain who reported an analgesic ADE associated with their chronic pain management were interviewed and asked to describe their analgesic related ADE. Written responses were content analyzed. Nineteen opioids were reported by 15, 11 NSAIDs were reported by 8, and acetaminophen was reported by 2 older adults as associated with an ADE...

An estimated 30% of Americans with hepatitis C virus (HCV) pass through a jail or prison annually. One in 7 incarcerated persons is viremic. Screening and treatment is cost-effective and beneficial to society as a whole. Yet at current (2018) levels of funding for HCV management, prisons are not aggressively seeking cases; few incarcerated persons with HCV actually receive treatment. This article explores barriers to screening for and treating hepatitis C in state prisons, and ways that states may overcome these barriers, such as nominal pricing...

Much progress with respect to congenital Zika virus (ZIKV) pathogenesis has been achieved after the 2015 outbreak in Brazil. It is now accepted that ZIKV is vertically transmitted, infects cells of the developing central nervous system and the placenta, yet it is unclear to what extent placental affection contributes to the development of congenital ZIKV. The association between fulminant villitis and severe fetal involvement emerges as a possibility. ZIKV is unique among the Flaviviruses in its ability to be sexually transmitted, possibly responsible for its teratogenicity...

Porcine reproductive and respiratory syndrome virus (PRRSV) shows characteristic antibody-dependent enhancement (ADE) of infection and causes porcine systemic inflammation, which is similar to a type I allergic reaction; however, the role of porcine FcεRI in ADE is still unclear. In this study, the expression of different Fc receptors (FcRs) on macrophages was investigated in a PRRSV 3D4/21 cell infection model in the presence or absence of PRRSV antibody. The transcription level of FcγII and FcεRI was significantly up-regulated under PRRSV-antibody complex infection...

Jointly identifying brain diseases and predicting clinical scores have attracted increasing attention in the domain of computer-aided diagnosis using magnetic resonance imaging (MRI) data, since these two tasks are highly correlated. Although several joint learning models have been developed, most existing methods focus on using human-engineered features extracted from MRI data. Due to the possible heterogeneous property between human-engineered features and subsequent classification/regression models, those methods may lead to sub-optimal learning performance...

Several prominent public health hazards [29] that occurred at the beginning of this century due to adverse drug events (ADEs) have raised international awareness of governments and industries about pharmacovigilance (PhV) [6,7], the science and activities to monitor and prevent adverse events caused by pharmaceutical products after they are introduced to the market. A major data source for PhV is large-scale longitudinal observational databases (LODs) [6] such as electronic health records (EHRs) and medical insurance claim databases...

Background: The consumption of acidified beverages, associated with lower mineralization of primary enamel, is the ideal combination for the development and progression of dental erosion. The objective of this study is to analyze the erosive capacity and the surface roughness of primary teeth enamel after exposure to three different brands of grape juices. Material and Methods: Forty enamel blocks of primary teeth were obtained, attened and polished. They were submitted to initial surface roughness analysis (baseline), and randomly assigned into four groups (n = 10): NAT: natural grape juice (Campo Largo); IND: industrialized grape juice (Dell Vale Kapo); SOY: soy-based grape juice (Ades); and CONT (control): artificial saliva...

Graphene and its derivatives have recently attracted much attention for sensing and deactivating pathogens. However, the mechanism of multivalent interactions at the graphene-pathogen interface is not fully understood. Since different physicochemical parameters of graphene play a role at this interface, control over graphene's structure is necessary to study the mechanism of these interactions. In this work, different graphene derivatives and also zwitterionic graphene nanomaterials (ZGNMs) were synthesized with defined exposure, in terms of polymer coverage and functionality, and isoelectric points...

Antibody-dependent enhancement (ADE) is a phenomenon in which preexisting poorly neutralizing antibodies leads to enhanced infection. It is a serious concern with mosquito-borne flaviviruses such as Dengue virus (DENV) and Zika virus (ZIKV). In vitro experimental evidences have indicated the preventive, as well as a pathogenicity-enhancing role, of preexisting DENV antibodies in ZIKV infections. ADE has been confirmed in DENV but not ZIKV infections. Principally, the Fc region of the anti-DENV antibody binds with the fragment crystallizable gamma receptor (FcγR), and subsequent C1q interactions and immune effector functions are responsible for the ADE...

Disruptions of dopamine (DA) signaling contribute to a broad spectrum of neuropsychiatric disorders, including attention-deficit hyperactivity disorder (ADHD), addiction, bipolar disorder and schizophrenia. Despite evidence that risk for these disorders derives from heritable variation in DA-linked genes, a better understanding is needed of the molecular and circuit context through which gene variation drives distinct disease traits. Previously, we identified the DA transporter (DAT) variant Val559 in subjects with ADHD and established that the mutation supports anomalous DAT-mediated DA efflux (ADE)...

To simultaneously achieve the low photon energy loss (Eloss) and the broad spectral response, the molecular design of the efficient wide band-gap (WBG) donor polymer with a deep HOMO level is of critical importance in fullerene-free polymer solar cells (PSCs). Herein, we developed a new benzodithiophene unit, i.e., DTBDT-EF and conducted systematic investigations on a WBG DTBDT-EF-based donor polymer, namely, PDTB-EF-T. Due to the synergistic electron-withdrawing effect of the fluorine atom and ester group, PDTB-EF-T exhibits higher oxidation potential, i...

Background: A traumatic ulcer caused by diabetes mellitus (DM) is a lesion caused by an increase in advanced glycosylation end products (AGEs), which takes a long time to heal. AGEs cause angiogenesis, vasculogenesis and a decrease in leukocytes. Fibroblast proliferation and the number of glycosaminoglycans decline, thereby inhibiting the formation of granulation tissue, collagen deposition and platelet derivatives growth factor. The application of topical propolis extract gel to ulcers has an anti-inflammatory function, triggers angiogenesis and accelerates wound healing...
