Human cytomegalovirus (HCMV) is the most common congenitally transmitted pathogen worldwide, impacting an estimated 1 million newborns annually. Congenital HCMV (cCMV) infection is a major global contributor to long-term neurologic deficits, including deafness, microcephaly, neurodevelopmental delay, as well as fetal loss and occasional infant mortality. Accordingly, a maternal vaccine to prevent cCMV continues to be a top public health priority. Nevertheless, we remain without a licensed vaccine. Maternal immunity provides partial protection, as the risk of vertical HCMV transmission from chronically infected mothers is reduced compared to settings in which the mother is newly infected during pregnancy...

BACKGROUND: Opinions differ as to the need of a lateral radiograph for diagnosing community acquired pneumonia in children referred to the emergency department. A lateral radiograph increases the ionizing radiation burden but at the same time may improve specificity and sensitivity in this population. OBJECTIVES: To determine the value of the frontal and lateral chest radiographs compared to frontal view stand-alone images for the management of children with suspected community acquired pneumonia seen in a pediatric emergency department...

Neurofibromatosis type 1 (NF1), a common genetic disorder with a birth incidence of 1:2,000-3,000, is characterized by a highly variable clinical presentation. To date, only two clinically relevant intragenic genotype-phenotype correlations have been reported for NF1 missense mutations affecting p.Arg1809 and a single amino acid deletion p.Met922del. Both variants predispose to a distinct mild NF1 phenotype with neither externally visible cutaneous/plexiform neurofibromas nor other tumors. Here, we report 162 individuals (129 unrelated probands and 33 affected relatives) heterozygous for a constitutional missense mutation affecting one of five neighboring NF1 codons-Leu844, Cys845, Ala846, Leu847, and Gly848-located in the cysteine-serine-rich domain (CSRD)...

This article lays out an agenda for research on the establishment of psy cultures in Latin America. It begins by analyzing some of the debates on the nature of psychoanalysis, a discipline located between the sciences, philosophy and common sense. It argues that the place of psy cultures needs to be problematized as emerging out of modernity in a cultural space like Latin America, where the very concept of modernity differs greatly from that of central countries.

This article explores the mechanisms underlying the formation of a new category in the Israeli therapeutic field-"national trauma." By comparing the two different paths of emergence of this category, the research reexamines the meaning of Hacking's concept "looping effect" and, in particular, the issue of awareness of the categorized individuals and the categorizing knowledge-producers to the effects of a categorization. This study demonstrates that the formation of "national trauma" is both an intentional product of the efforts and ideology of practitioners and an unintentional outcome of their scientific and interventional activities...

While theory offers clear predictions for when recombination will evolve in changing environments, it is unclear what natural scenarios can generate the necessary conditions. The Red Queen hypothesis provides one such scenario, but it requires antagonistic host-parasite interactions. Here we present a novel scenario for the evolution of recombination in finite populations: the genomic storage effect due to phenotypic plasticity. Using analytic approximations and Monte-Carlo simulations, we demonstrate that balanced polymorphism and recombination evolve between a target locus that codes for a seasonally selected trait and a plasticity modifier locus that modulates the effects of target-locus alleles...

Precise assessment of treatment response in glioblastoma during combined anti-angiogenic and chemoradiation remains a challenge. In particular, early detection of treatment response by standard anatomical imaging is confounded by pseudo-response or pseudo-progression. Metabolic changes may be more specific for tumor physiology and less confounded by changes in blood-brain barrier permeability. We hypothesize that metabolic changes probed by magnetic resonance spectroscopic imaging can stratify patient response early during combination therapy...

The receptor tyrosine kinase Mer (MERTK) is a promising drug target in cancer, where it can influence the metastasis-promoting signaling of both tumor cells and immune cells alike; however, no small molecule probes currently exist to selectively image Mer. In this work, we design and synthesize a selective near-infrared fluorescent molecular probe of Mer (MERi-SiR). Confocal microscopy of metastases in mice reveals predominant probe accumulation in Mer-expressing tumor-associated macrophages.

BACKGROUND: People with PD are at high risk of developing cognitive impairment and dementia. Cross-sectional studies have identified candidate biomarkers associated with cognitive decline. However, longitudinal studies on this topic are rarer, and few have investigated the use of biomarker panels encompassing multiple modalities. The objective of this study was to find baseline predictors of cognitive decline in longitudinally followed, nondemented Parkinson's disease patients. METHODS: We performed a prospective cohort study of 100 PD patients with a median disease duration of 6...

Vaccinations have had tremendous success in the 20th century. However, in the 21st century, we are facing complex immunological issues in relation to controlling underlying infectious diseases. Therefore, new technologies are needed to develop vaccines against infectious diseases like respiratory syncytial virus, human immunodeficiency virus, and cytomegalovirus. In addition, recent emerging infections have taught us that we must prepare preventative measures in advance using our scientific abilities.

BACKGROUND: Minimally invasive specific biomarkers of neurodegenerative diseases (NDs) would facilitate patient selection and disease progression monitoring. We describe the assessment of circulating brain-enriched microRNAs as potential biomarkers for Alzheimer's disease (AD), frontotemporal dementia (FTD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). METHODS: In this case-control study, the plasma samples were collected from 250 research participants with a clinical diagnosis of AD, FTD, PD, and ALS, as well as from age- and sex-matched control subjects (n = 50 for each group), recruited from 2003 to 2015 at the University of Pennsylvania Health System, including the Alzheimer's Disease Center, the Parkinson's Disease and Movement Disorders Center, the Frontotemporal Degeneration Center, and the Amyotrophic Lateral Sclerosis Clinic...

Determining health literacy level is an important prerequisite for effective patient education. We assessed multiple dimensions of health literacy and sociodemographic predictors of health literacy in patients with neurofibromatosis. In 86 individuals with a confirmed diagnosis of neurofibromatosis 1 (NF1), neurofibromatosis 2 (NF2), or schwannomatosis, we assessed health literacy status using two HL tools-the adapted functional, communicative, and critical health literacy scale (adapted FCCHL) and health literacy assessment using talking touchscreen technology (Health LiTT)...

OBJECTIVES: Plexiform neurofibromas (PNs) are complex, histologically benign peripheral nerve sheath tumors that are challenging to measure by simple line measurements. Computer-aided volumetric segmentation of PN has become the recommended method to assess response in clinical trials directed at PN. Different methods for volumetric analysis of PN have been developed. The goal of this study is to test the level of agreement in volume measurements and in interval changes using two separate methods of volumetric magnetic resonance imaging analysis...

A growing evidence base supports expansion of partner notification in HIV testing services (HTS) in sub-Saharan Africa. In 2015, a cross-sectional study was conducted in Njombe region, Tanzania, to evaluate partner notification within facility-based HTS. Men and women newly diagnosed with HIV were enrolled as index clients and asked to list current or past sexual partners for referral to HTS. Successful partner referral was 2.5 times more likely among married compared to unmarried index clients and 2.2 times more likely among male compared to female index clients...

Many PHM strategies fall short because they fail to address three critical components that relate to patient-centeredness: patient-centered education, patient-centered social indicators, and patient-centered technology. Each of these three components is absolutely essential for population health strategies to work.

PURPOSE OF REVIEW: To describe the current knowledge on the cross-talk between connexins and microRNAs (miRs) in bone cells. RECENT FINDINGS: Connexins play a crucial role on bone development and maintenance, and disruptions in their abundance or localization can affect how bone perceives and responds to mechanical, hormonal, and pharmacological stimuli. Connexin expression can be modified by miRs, which modulate connexin mRNA and protein levels. Recently, different manners by which miRs and connexins can interact in bone have been identified, including mechanisms that mediate miR exchange between cells in direct contact through gap junctions, or between distant cells via extracellular vesicles (EVs)...
