Participatory research in health promotion: a critical review and illustration of rationales.

Health Promot Int 2022 Jun;37(Supplement_2):ii7-ii20

Department of Public and Occupation Health, Amsterdam UMC, University of Amsterdam, Amsterdam Public Health Research Institute, Meibergdreef 9, Amsterdam, 1105 AZ, The Netherlands.

In health promotion research, enthusiasm for patient and public involvement (PPI) is growing. However, a lack of conceptual clarity leads to ambiguities in participatory processes and purposes, and hampers efforts to achieve and evaluate PPI in research. This study provides an overview of its underlying reasons-or rationales-so as to better understand, guide and interpret PPI in research practice. Read More

Vector-borne pathogens in dogs from areas where leishmaniosis is endemic.

Vet Parasitol Reg Stud Reports 2022 Jul 9;32:100746. Epub 2022 Jun 9.

Department of Veterinary Medicine, University of Bari, Valenzano, Bari, Italy.

Many vector-borne pathogens (VBPs), including Ehrlichia canis and Dirofilaria immitis, may infect simultaneously dogs in areas where Leishmania infantum is endemic, especially in the tropics, where highly abundant arthropod vectors thrive. The aim of this study was to compare the frequency of simultaneous VBPs infection in Leishmania-positive and Leishmania-negative dogs. Animals enrolled in this study were divided in two groups (G1 and G2), G1 being comprised of L. Read More

Discriminating between Lyme neuroborreliosis and other central nervous system infections by use of biomarkers CXCL13 and IL-6.

Ticks Tick Borne Dis 2022 Jun 3;13(5):101984. Epub 2022 Jun 3.

Department of Clinical Microbiology, Lillebaelt Hospital - University Hospital of Southern Denmark, Denmark; Department of Regional Health Research, Faculty of Health Sciences, University of Southern Denmark, Denmark.

CXCL13 in cerebrospinal fluid has gradually become an established biomarker for Lyme neuroborreliosis (LNB), however the diagnostic performance of CXCL13 may be improved by the addition of IL-6, a non-specific infection biomarker. The aim of this study was to measure the concentrations of CXCL13 and IL-6 in cerebrospinal fluid, in the attempt to evaluate the diagnostic performance of these two biomarkers, in the differentiation between definite and possible LNB, as well as between LNB and other neuroinfections. This study used a cross-sectional design to quantify the levels of CXCL13 and IL-6 in cerebrospinal fluid (CSF) specimens from consecutive patients examined for central nervous system (CNS) infections at Lillebaelt Hospital in the Region of Southern Denmark.

Parallel Field-Effect Nanosensors Detect Trace Biomarkers Rapidly at Physiological High-Ionic-Strength Conditions.

ACS Sens 2022 Jun 14. Epub 2022 Jun 14.

Sensitivity and speed of detection are contradicting demands that profoundly impact the electrical sensing of molecular biomarkers. Although single-molecule sensitivity can now be achieved with single-nanotube field-effect transistors, these tiny sensors, with a diameter less than 1 nm, may take hours to days to capture the molecular target at trace concentrations. Here, we show that this sensitivity-speed challenge can be addressed using covalently functionalized double-wall CNTs that form many individualized, parallel pathways between two electrodes.

FbpA and FbpB Are Immunomodulatory Outer Surface Lipoproteins With Distinct Structures and Functions.

Front Immunol 2022 27;13:886733. Epub 2022 May 27.

Department of Microbiology and Immunology, Brody School of Medicine, East Carolina University, Greenville, NC, United States.

Pathogens that traffic in the blood of their hosts must employ mechanisms to evade the host innate immune system, including the complement cascade. The Lyme disease spirochete, , has evolved numerous outer membrane lipoproteins that interact directly with host proteins. Compared to Lyme disease-associated spirochetes, relatively little is known about how an emerging tick-borne spirochetal pathogen, , utilizes surface lipoproteins to interact with a human host.

Climate Changes Exacerbate the Spread of and the Occurrence of Lyme Borreliosis and Tick-Borne Encephalitis in Europe-How Climate Models Are Used as a Risk Assessment Approach for Tick-Borne Diseases.

Int J Environ Res Public Health 2022 May 27;19(11). Epub 2022 May 27.

Laboratory of Reliability and Quality Control in Laboratory Hematology (HemQcR), Department of Biomedical Sciences, School of Health and Care Sciences, University of West Attica, 12243 Athens, Greece.

Climate change has influenced the transmission of a wide range of vector-borne diseases in Europe, which is a pressing public health challenge for the coming decades. Numerous theories have been developed in order to explain how tick-borne diseases are associated with climate change. These theories include higher proliferation rates, extended transmission season, changes in ecological balances, and climate-related migration of vectors, reservoir hosts, or human populations.

Seropositivity of main vector-borne pathogens in dogs across Europe.

Parasit Vectors 2022 Jun 6;15(1):189. Epub 2022 Jun 6.

Institute for Parasitology and Tropical Veterinary Medicine, Freie Universität Berlin, Berlin, Germany.

Background: Canine vector-borne disease (CVBD) has been an area of increasing interest in Europe over the last few decades, and there have been changes in the prevalence and distribution of many of these diseases. Monitoring CVBD infections in Europe is often done by individual countries, but aggregated data for the European countries are helpful to understand the distribution of CVBDs.

Methods: We used an extensive retrospective database of results from point-of-care rapid enzyme-linked immunosorbent assay (ELISA) tests on dogs across Europe to identify distribution and seropositivity in animals tested for selected CVBDs (Anaplasma spp. Read More

The Putative Endonuclease Activity of MutL Is Required for the Segmental Gene Conversion Events That Drive Antigenic Variation of the Lyme Disease Spirochete.

Front Microbiol 2022 19;13:888494. Epub 2022 May 19.

Department of Biochemistry and Molecular Biology, Cumming School of Medicine, Snyder Institute for Chronic Diseases, University of Calgary, Calgary, AB, Canada.

The Lyme disease spirochete , encodes an elaborate antigenic variation system that promotes the ongoing variation of a major surface lipoprotein, VlsE. Changes in VlsE are continual and always one step ahead of the host acquired immune system, which requires 1-2 weeks to generate specific antibodies. By the time this happens, new VlsE variants have arisen that escape immunosurveillance, providing an avenue for persistent infection. Read More

Relevance of Spatial and Temporal Trends in Nymphal Tick Density and Infection Prevalence for Public Health and Surveillance Practice in Long-Term Endemic Areas: A Case Study in Monmouth County, NJ.

J Med Entomol 2022 Jun 5. Epub 2022 Jun 5.

Tick-borne Disease Program, Monmouth County Mosquito Control Division, 1901 Wayside Road, Tinton Falls, NJ 07724, USA.

Tick-borne diseases are a growing public health problem in the United States, and the US northeast has reported consistently high case rates for decades. Monmouth County, New Jersey, was one of the earliest jurisdictions to report Lyme disease cases in 1979 and reports several hundred cases per year nearly 40 yr later. In the time since, however, tick-borne health risks have expanded far beyond Lyme disease to include a variety of other bacterial pathogens and viruses, and additional vectors, necessitating a continually evolving approach to tick surveillance.
