PurposeCompression socks are frequently used in the treatment and prevention of lower-limb pathologies; however, when combined with endurance-based exercise, the impact of compression socks on haemostatic activation remains unclear.ObjectivesTo investigate the effect of wearing compression socks on coagulation and fibrinolysis following a marathon.MethodsSixty-seven participants [43 males (mean ± SD: age: 46.7 ± 10.3 year) and 24 females (age: 40.0 ± 11.0 year)] were allocated into a compression (SOCK, n = 34) or control (CONTROL, n = 33) group. Venous blood samples were obtained 24 h prior to and immediately POST-marathon, and were analyzed for thrombin–anti-thrombin complex (TAT), tissue factor (TF), tissue factor pathway inhibitor (TFPI), and D-Dimer.ResultsCompression significantly attenuated the post-exercise increase in D-Dimer compared to the control group [median (range) SOCK: + 9.02 (− 0.34 to 60.7) ng/mL, CONTROL: + 25.48 (0.95–73.24) ng/mL]. TF increased following the marathon run [median (range), SOCK: + 1.19 (− 7.47 to 9.11) pg/mL, CONTROL: + 3.47 (− 5.01 to 38.56) pg/mL] in all runners. No significant post-exercise changes were observed for TAT and TFPI.ConclusionsWhile activation of coagulation and fibrinolysis was apparent in all runners POST-marathon, wearing compression socks was shown to reduce fibrinolytic activity, as demonstrated by lower D-Dimer concentrations. Compression may reduce exercise-associated haemostatic activation when completing prolonged exercise.

As Rhagodia preissii had shown significant in vitro anthelmintic activity in a previous study, we examined the effect of including this shrub in the diet of sheep infected with Trichostrongylus colubriformis. Worm-infected merino wethers were grazed for 7 weeks on either R. preissii or annual pasture, and faecal egg counts (FECs) were conducted weekly. Plant material was collected weekly from eaten and uneaten plants, and analysed for levels of plant secondary metabolites (tannins, oxalates, saponins) and in vitro anthelmintic activity. While mean FECs were consistently lower in sheep grazing R. preissii compared to pasture (reductions of 20–74%), the differences were not significant. There was no relationship between grazing preference (eaten or uneaten) and in vitro anthelmintic activity of plant extracts. The levels of saponins and oxalates did not correlate with grazing preference or in vitro anthelmintic activity, while tannins were not responsible for the anthelmintic activity. While the identity of the grazing deterrent and in vitro anthelmintic compounds remain unknown, the presence of plants which were both highly preferred by the sheep and showed in vitro anthelmintic activity indicates a potential to develop the species as an anthelmintic shrub through selection of shrub populations dominated by such plants.

Background With various infectious disease risks to passenger ship travellers, guidance for infectious disease prevention, mitigation and management (PMM) exists. Emerging infections and emergencies necessitate updated, context-specific guidelines and practices. New evidence for infection PMM must be translated into guidance for governmental authorities and the passenger ship industry. Under the European HEALTHY SAILING project, we conducted a scoping review of publications in PubMed, Scopus and grey literature for scientific articles, regulations, guidelines and policies describing infectious disease PMM in seaports, cruise, ferry, expedition and river cruise ships between 1990 and 2023. Main findings Of 620 publications most were peer-reviewed articles (57.7%) and technical guidance (27.9%), followed by reports/other documents (9.1%), industry guidance (3.4%) and legislation (1.9%). Half (50.5%) of all publications addressed respiratory illnesses, fewer addressed gastroenteritis (11.5%), Legionnaire’s (6.1%), other vaccine-preventable (3.2%), vector-borne (1.6%) and sexually transmitted (1.0%) diseases. Most publications focus on infectious disease in seagoing cruise ships (75.7%) compared to ferries, expedition and river cruise ships (26.6%, 16.9%, 16.3%, respectively). Fewer publications addressed seaports (39.0%), shore-side personnel (19.7%) and port communities (2.4%). Most literature was published between 2020 and 2023 (50.2%) with a peak addressing respiratory illnesses (264 publications) during this period. A trend in volume and type was observed based on public health emergencies associated with the publication year. Conclusions Peer-reviewed articles and guidance primarily address respiratory and gastrointestinal illnesses, seagoing cruise ships and onboard populations. Gaps on the following topics exist: other infectious disease types; other passenger ship types; land-based personnel and port communities. Future research could assess risk factors and PMM measure effectiveness considering vaccine-preventable, vector-borne and sexually transmitted diseases. The evidence-base should be strengthened to produce guidelines targeting specificities of seaports, ferries, expedition and river cruise ships. Developing guidelines to standardise passenger ship outbreak investigation reporting could help evaluate PMM measure effectiveness, the impact of passenger ship travel on port communities and vice versa. Modern passenger ship experiences—from educational to elderly focused cruising—present diverse public health risks, requiring continuous efforts by public health authorities and the shipping industry. While outside the review’s scope, measures may impact travellers’ mental health, necessitating strategies when designing and implementing PMM measures.
