Background: While the worldwide endemicity of tick-borne encephalitis (TBE) has been increasing, a lack of awareness of the risks of this life-threatening disease may be leading to an underutilization of preventive measures among travellers to TBE-endemic regions. This study's objectives were to assess travellers' awareness of TBE and advice-seeking attitudes, and to evaluate practices of travel clinics regarding pre-travel advice.Methods: We used an online questionnaire to identify individuals aged 18-65 years residing in the UK, Germany, Canada and Sweden, who had travelled to TBE-endemic countries between 2013 and 2016. This sample was defined as the visit-risk sample. Of these, the first 375 respondents who reported that they had engaged in pre-defined at-risk activities (e.g. hiking in forests) were asked to complete an additional online survey and were included in the activity-risk sub-sample. We also used an online/phone questionnaire to interview travel clinic personnel.Results: The TBE visit-risk sample included 4375 individuals; 69% had heard of the disease and 32% had heard of a TBE vaccine. Before travelling, travellers most commonly sought information online (26%); fewer travellers consulted family doctors (8%) or travel clinics (5%). In the activity-risk sample, 79% of the travellers were aware of at least one correct TBE prevention measure; however, only 15% reported being vaccinated within the past 3 years, with 11% of vaccinated travellers doing so following a clinic's recommendation. One hundred and eighty travel clinic representatives responded and reported that TBE vaccination was recommended to an average of 61% of travellers to endemic regions. Vaccination-reminder services such as follow-up appointments, e-mail and text reminders were offered by 50% of the clinics.Conclusions: There is a need to increase awareness of the risk and prevention of TBE among travellers to endemic countries, and travel clinics could play an important role in this process. 5975671594001tay062media15975671594001.

Background: Extensive global experience shows that rabies pre-exposure prophylaxis (PrEP) through vaccination is effective and well tolerated, yet many travellers opt not to be vaccinated when travelling to rabies-endemic countries. Previous research has identified several factors influencing the choices travellers make to reduce the risk of rabies, including cost, time constraint and perspective on the importance of vaccination. The objectives of this study were to assess travellers' awareness of rabies and advice-seeking attitudes and to evaluate travel clinics practices regarding rabies pre-travel advice.Methods: We surveyed individuals aged 18-65 years residing in the UK, Germany, Canada and Sweden who had travelled to rabies-endemic countries between 2013 and 2016 and defined this as the rabies visit-risk sample. The first 850 respondents from the visit-risk sample who had undertaken pre-defined at-risk activities (e.g. contact with animals during the trip) completed an additional 15-min online questionnaire and were included in the activity-risk subsample. We also interviewed travel clinic personnel using a 25-min online or phone questionnaire.Results: The visit-risk sample included 4678 individuals. Many sought pre-travel health information online (33%) or talked to a family doctor (24%). Within the activity-risk subsample, 83% of travellers were aware of at least a few basic facts about rabies, and 84% could identify at least one correct rabies prevention measure; 49% were aware of a rabies vaccine, however, only 8% reported receiving PrEP vaccination within the past 3 years. Among 180 travel clinic respondents, 21% reported recommending PrEP against rabies to all travellers to rabies-endemic countries. Travel clinics estimated that 81% of travellers complete their travel vaccination schedules and reported sending reminders by e-mails (38%), text (38%), phone calls (37%) or by using vaccination cards (37%).Conclusions: These findings suggest that although travellers had frequently heard of rabies, awareness of the risks of this serious infectious disease was relatively low. 5975671594001tay062media15975671594001.

With slow growth rates, late maturity and a high maximum age of 100 years or more, orange roughy can be classified as a vulnerable deepwater fish species that can only sustain low rates of exploitation. Historical patterns of exploitation associated with this species suggest that it is currently not possible to manage its fisheries in the Northeast Atlantic sustainably, and the total allowable catch for orange roughy has been gradually reduced to zero for European fisheries since 2010. Orange roughy to the west of Ireland and Britain occurs on distinct bathymetric features (seamounts, hills and canyons) as well as on flat ground along the continental slope. Productivity-susceptibility analysis (PSA) was performed to evaluate the biological vulnerability of orange roughy in relation to other deepwater species and the risk that recent and current fisheries pose to its populations in the study area. Time-dependant PSA, based on the spatial overlap between orange roughy distribution and recent and current deepwater fisheries demonstrated a strong reduction in risk over time when fisheries stopped directed targeting practices and continued with mixed deepwater trawl fisheries. Some spatial overlap between the species and current fisheries remains, and while the method can show relative risk reduction, it cannot provide information on whether the risk is low enough to allow the recovery of depleted populations.

Longitudinal analyses of the innate immune system, including the earliest time points, are essential to understand the immunopathogenesis and clinical course of coronavirus disease (COVID-19). Here, we performed a detailed characterization of natural killer (NK) cells in 205 patients (403 samples; days 2 to 41 after symptom onset) from four independent cohorts using single-cell transcriptomics and proteomics together with functional studies. We found elevated interferon (IFN)-α plasma levels in early severe COVD-19 alongside increased NK cell expression of IFN-stimulated genes (ISGs) and genes involved in IFN-α signaling, while upregulation of tumor necrosis factor (TNF)-induced genes was observed in moderate diseases. NK cells exert anti-SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) activity but are functionally impaired in severe COVID-19. Further, NK cell dysfunction may be relevant for the development of fibrotic lung disease in severe COVID-19, as NK cells exhibited impaired anti-fibrotic activity. Our study indicates preferential IFN-α and TNF responses in severe and moderate COVID-19, respectively, and associates a prolonged IFN-α-induced NK cell response with poorer disease outcome., Competing Interests: Declaration of interests P.-A.K. and F.I.S. are cofounders and shareholders of Dioscure Therapeutics SE.
