Mpox stigma among men who have sex with men in the Netherlands: Underlying beliefs and comparisons across other commonly stigmatized infections

Hanne M. L. Zimmermann, Thomas Gültzow, Tamika A. Marcos, Haoyi Wang, more

Journal of Medical Virology > 95 > 9 > n/a - n/a

People with or at risk for mpox are likely to be stigmatized because of analogies to other sexually transmitted infections. Stigma is driven by beliefs about the perceived severity of the condition and perceived responsibility for acquiring the condition, both in broader society and individual responsibility. We explored these beliefs and compared them across mpox, human immunodeficiency virus (HIV),...

The social meanings of PrEP use – A mixed‐method study of PrEP use disclosure in Antwerp and Amsterdam

Thijs Reyniers, Hanne M. L. Zimmermann, Udi Davidovich, Bea Vuylsteke, more

Sociology of Health & Illness > 43 > 6 > 1311 - 1327

Pre‐Exposure Prophylaxis (PrEP) is a novel HIV prevention tool. PrEP stigma is a frequently reported barrier, while social disclosure of PrEP use may be an important facilitator. We explored how PrEP users managed PrEP use disclosure using a symbolic interactionist approach. We interviewed 32 participants from two PrEP demonstration projects (Be‐PrEP‐ared, Antwerp; AMPrEP, Amsterdam). We validated...

Entangled Aeglidae (Decapoda, Anomura): Additional evidence for cryptic species

Bianca L. Zimmermann, Ivanice Buzatto, Sandro Santos, Federico Giri, more

Zoologica Scripta > 50 > 4 > 473 - 484

Cryptic species are a major challenge for morphologically based species identification. Molecular approaches to species delimitation can be a valuable tool to provide preliminary taxonomic hypotheses and significantly complements morphological taxonomy. In South America, the freshwater crabs of the genus Aegla have sparked much interest as they are key species in the often‐endangered freshwater ecosystems...

Family Relations > 70 > 3 > 808 - 822

Objective To examine (a) associations among coparental interaction (cooperation, overt conflict, covert conflict) and father involvement (engagement, in‐kind financial support), (b) associations among the three dimensions of coparental interaction, and (c) associations among the two dimensions of father involvement, shortly after divorce. Background Family relationships change shortly after divorce,...

Gerd‐Dieter Willmund, Julius Heß, Christian Helms, Florian Wertenauer, more

Suicide and Life‐Threatening Behavior > 49 > 5 > 1497 - 1509

Background The last 10 years have seen an increase in the number of suicides in the US Armed Forces. Accordingly, the topic of suicides in the German military has received a lot of attention in media and science alike. Methods This study retrospectively examined all suicides (N = 107) committed by active, nonretired German military personnel from 2010 to the end of 2014, analyzing archived medical...

Evaluation of a New Catheter for Simultaneous Intracranial Pressure Monitoring and Cerebral Spinal Fluid Drainage: A Pilot Study

Xiuyun Liu, Lara L. Zimmermann, Nhi Ho, Paul Vespa, more

Neurocritical Care > 2019 > 30 > 3 > 617-625

Objectives Intracranial pressure (ICP) monitoring is a common practice when treating intracranial pathology with risk of elevated ICP. External ventricular drain (EVD) insertion is a standard approach for both monitoring ICP and draining cerebrospinal fluid (CSF). However, the conventional EVD cannot serve these two purposes simultaneously because it cannot accurately measure ICP and its pulsatile...

Susan E. Slaughter, Gabrielle L. Zimmermann, Megan Nuspl, Heather M. Hanson, more

BMC Medical Research Methodology > 2017 > 17 > 1 > 1-11

Background As implementation science advances, the number of interventions to promote the translation of evidence into healthcare, health systems, or health policy is growing. Accordingly, classification schemes for these knowledge translation (KT) interventions have emerged. A recent scoping review identified 51 classification schemes of KT interventions to integrate evidence into healthcare practice;...

Performance improvement of a monolithically integrated C-Band receiver enabled by an advanced photonic BiCMOS process

S. Lischke, D. Knoll, M. H. Eissa, M. Kroh, more

2017 IEEE Bipolar/BiCMOS Circuits and Technology Meeting (BCTM) > 50 - 53

2017 IEEE Bipolar/BiCMOS Circuits and Technology Meeting - BCTM

A monolithically integrated C-band receiver is used to demonstrate the potential of an advanced photonic BiCMOS process. We show that the particular SiGe HBTs integrated in this process strongly improve the receiver's frequency response, BER and noise behavior, compared to the same circuit fabricated in a previous process generation featuring slower transistors.

High-speed, high-responsivity Ge photodiode with NiSi contacts for an advanced photonic BiCMOS technology

S. Lischke, D. Knoll, D. Wolansky, M. Kroh, more

2017 IEEE 14th International Conference on Group IV Photonics (GFP) > 61 - 62

2017 IEEE 14th International Conference on Group IV Photonics (GFP)

We will show that contacting a high-performance Ge photodiode with NiSi instead of CoSi₂ has no negative effect. This result strongly supports the development of an advanced photonic BiCMOS process where the RF performance of SiGe HBTs can take strong benefit from the “cold” NiSi.

K. Voigt, V. Brulis, K. Petermann, L. Zimmermann

2017 IEEE 14th International Conference on Group IV Photonics (GFP) > 143 - 144

2017 IEEE 14th International Conference on Group IV Photonics (GFP)

We compare the performances of different spot size converter (SSC) designs consisting of backend waveguide arrays (“dot-like”, “cross-like”, “stripes”, “box”) at the facet, adiabatically coupled to tapered Si waveguides. For the study, we use SiON waveguides and a low index step “box” waveguide.

Concepts and procedures for mapping food and health research infrastructure: New insights from the EuroDISH project

Kerry A. Brown, Lada Timotijević, Marjolein Geurts, Johanne L. Arentoft, more

Trends in Food Science & Technology > 2017 > 63 > C > 113-131

Recent initiatives in Europe have encouraged the formalisation of research infrastructure to unify fragmented facilities, resources and services; and to facilitate world-class research of complex public health challenges, such as those related to non-communicable disease. How this can be achieved in the area of food and health has, to date, been unclear.This commentary paper presents examples of the...

T. Maisch, A. K. Bosserhoff, P. Unger, J. Heider, more

Environmental and Molecular Mutagenesis > 58 > 3 > 172 - 177

Cold atmospheric argon plasma is recognized as a new contact free approach for the decrease of bacterial load on chronic wounds in patients. So far very limited data are available on its toxicity and mutagenicity on eukaryotic cells. Thus, the toxic/mutagenic potential of cold atmospheric argon plasma using the MicroPlaSter β^®, which has been used efficiently in humans treating chronic and acute wounds,...

M. R. Wilson, L. L. Zimmermann, E. D. Crawford, H. A. Sample, more

American Journal of Transplantation > 17 > 3 > 803 - 808

Solid organ transplant patients are vulnerable to suffering neurologic complications from a wide array of viral infections and can be sentinels in the population who are first to get serious complications from emerging infections like the recent waves of arboviruses, including West Nile virus, Chikungunya virus, Zika virus, and Dengue virus. The diverse and rapidly changing landscape of possible causes...
