Background: Schistosomiasis japonica remains a major public health and socio-economic concern in Southeast-Asia. Sensitive and accurate diagnostics can play a pivotal role in achieving disease elimination goals. Methods: We previously reported a novel droplet digital-PCR (ddPCR) assay targeting the mitochondrial gene nad1 to diagnose schistosomiasis japonica. The tool identified both pre-patent and patent infections using Schistosoma japonicum DNA isolated from serum, urine, salivary glands and faeces in a murine model...

Doreen Walther, Helge Kampen
The citizen science project 'Mueckenatlas' (mosquito atlas) was implemented in early 2012 to improve mosquito surveillance in Germany. Citizens are asked to support the spatiotemporal mapping of culicids by submitting mosquito specimens collected in their private surroundings. The Mueckenatlas has developed into an efficient tool for data collection with close to 30,000 mosquitoes submitted by the end of 2015. While the vast majority of submissions included native mosquito species, a small percentage represented invasive species...

Serologic cross-reactivity, a hallmark of orthopoxvirus (OPXV) infection, makes species-specific diagnosis of infection difficult. In this study, we used a Variola virus (VARV) proteome microarray to characterize and differentiate antibody responses to non-vaccinia OPXV infections from smallpox vaccination. The profile of two-case patients infected with newly discovered OPXV, Akhmeta virus (AKMV), exhibited antibody responses of greater intensity and broader recognition of viral proteins and includes the B21/22 family glycoproteins not encoded by vaccinia virus (VACV) strains used as vaccines...

Increasing the volume, strengthening the quality, and proactively using data of human immunodeficiency virus (HIV) load testing are pivotal to limiting the threat of HIV drug resistance (HIVDR) accumulation,and allow for optimal case-based HIVDR surveillance. Triangulation of viral load (VL) and HIVDR testing data could be pursued to answer key questions and translate data and results for program and public policy. Identification of virologic failure and early management mitigates the greater risk of HIVDR...

The mosquitoes Aedes (Stegomyia) aegypti (L.)(Diptera:Culicidae) and Ae. (Stegomyia) albopictus (Skuse) (Diptera:Culicidae) transmit dengue, chikungunya, and Zika viruses and represent a growing public health threat in parts of the United States where they are established. To complement existing mosquito presence records based on discontinuous, non-systematic surveillance efforts, we developed county-scale environmental suitability maps for both species using maximum entropy modeling to fit climatic variables to county presence records from 1960-2016 in the contiguous United States...

Background: Enterovirus A71 (EV-A71) is the major cause of severe hand, foot and mouth disease and viral encephalitis in children across the Asia-Pacific region, including in Vietnam which has experienced a high burden of disease in recent years. Multiple subgenogroups (C1, C4, C5 and B5) concurrently circulate in the region with a large variation in epidemic severity. The relative differences in their evolution and epidemiology were examined within Vietnam and globally. Methods: A total of 752 VP1 gene sequences were analysed (413 generated in this study combined with 339 obtained from GenBank), collected from patients in 36 provinces in Vietnam during 2003-2013 along with epidemiological metadata...

Objectives: Oxazolidinone resistance is a serious limitation in the treatment of MDR Enterococcus infections. Plasmid-mediated oxazolidinone resistance has been strongly linked to animals where the use of phenicols might co-select resistance to both antibiotic families. Our goal was to assess the diversity of genes conferring phenicol/oxazolidinone resistance among diverse enterococci and to characterize the optrA genetic environment. Methods: Chloramphenicol-resistant isolates (>16 mg/L, n = 245) from different sources (hospitals/healthy humans/wastewaters/animals) in Portugal, Angola and Tunisia (1996-2016) were selected...

FOXA1 is a transcription factor involved in androgen signaling with relevance for lineage specific gene expression of the prostate. The expression was analyzed by immunohistochemistry on a tissue microarray containing 11,152 prostate cancer specimens. Results were compared to tumor phenotype, biochemical recurrence, androgen receptor expression, ERG status and other recurrent genomic alterations. FOXA1 expression was detectable in 97.6% of 8,227 interpretable cancers and considered strong in 28.5%, moderate in 46...

Backgroud: Acute flaccid myelitis (AFM) is an acute flaccid paralysis (AFP) syndrome with spinal motor neuron involvement of unknown etiology. We investigated the characteristics and prognostic factors of AFM clusters coincident with an enterovirus D68 (EV-D68) outbreak in Japan during autumn 2015. Methods: An AFM case series study was conducted following a nationwide survey from August to December 2015. Radiographic and neurophysiologic data were subjected to centralized review, and virology studies were conducted for available specimens...

PURPOSE OF REVIEW: Active surveillance is an established treatment option for men with localized, low-risk prostate cancer (CaP). It entails the postponement of immediate therapy with the option of delayed intervention upon disease progression. The rate of clinical progression and need for treatment on active surveillance is approximately 50% over 15 years. The present review summarizes recent data on current methods, attempting to prevent clinical progression. RECENT FINDINGS: Patient selection for active surveillance is the first mandatory step required to lower progression...

Anne-Rose Robbins, Elke D Reissing
According to objectification theory, women become culturally desexualized during midlife and have the opportunity to let go of their propensity to self-objectify. In young women, self-objectification is negatively related to sexual adjustment. Yet little is known about what could ameliorate this relationship or whether it continues after midlife. Body appreciation (i.e., acceptance and positive regard for the body) has been substantiated as a contributor to improved sexual adjustment in young and older women alike...

Objectives: Acute carbon monoxide poisoning is common and often severe. Domestic causes have been extensively documented, while occupational exposures have been reported less frequently. We analyse occupational carbon monoxide poisonings from the available data of the carbon monoxide poisoning surveillance network for Paris and its region, and identify predictive factors of severity for occupational poisoning in order to identify priority prevention actions. Methods: We retrospectively reviewed all events of acute accidental carbon monoxide exposures which occurred in the Paris region, at the work place, and notified to the surveillance network from 1 January 2005 to 31 December 2011...
