BackgroundDengue virus (DENV) infection can manifest as dengue fever (DF) or dengue hemorrhagic fever (DHF), although DHF often becomes clinically apparent around defervescence. How complement components and other immune responses evolve over the course of illness from the febrile to recovery phase remains incompletely defined. This study characterized circulating complement activation and immune mediators in DF and DHF using paired febrile and early-recovery samples.
MethodsWe conducted a multicenter prospective cohort study at five hospitals in Indonesia between November 2024 and October 2025. Patients with laboratory-confirmed dengue were classified as DF or DHF. Plasma concentrations of PTX3, C5a, IL-6, IL-10, IL-8, and CXCL10 were quantified in paired febrile and early recovery phase samples. Between-group differences, within-patient changes between the two time points, and correlations among immune mediators were assessed using appropriate statistical methods.
ResultsWe included 110 confirmed dengue cases in the analysis. PTX3 and IL-10 levels were significantly higher in DHF than in DF during early recovery, whereas no mediator differed significantly between severity groups during the febrile phase. Across phases, C5a increased significantly from febrile to early recovery in DHF but not in DF, whereas PTX3 decreased significantly in DF but not in DHF. Correlations among mediators were generally weak to moderate, with a reproducible PTX3–IL-10–CXCL10 module observed across both phases.
ConclusionThe measured mediators did not distinguish DF from DHF during the febrile phase, but differences emerged in early recovery, with higher PTX3 and IL-10 in DHF. Across phases, C5a increased significantly from febrile to early recovery in DHF, whereas PTX3 decreased significantly only in DF. A PTX3–IL-10–CXCL10 module was observed at both time points. Together, these patterns suggest that within-patient changes around defervescence or in the early recovery may be informative and warrant evaluation in larger, prospectively timed cohorts.
The overall aim of the present project is to increase healthcare professionals’ ability to ask about exposure and to identify individuals exposed to intimate partner violence (IPV). The project will evaluate the effects of three different interventions that can be assumed to increase healthcare professionals’ ability to ask and identify individuals who have been or are exposed to IPV.
This project has a quasi-experimental design. After a 2-month baseline period, participating care units (primary health centres, maternal health clinics and youth guidance clinics) will be assigned to one of three interventions to potentially increase the ability to enquire and identify patient exposure to IPV: (1) healthcare professionals’ use of a standardised questionnaire about exposure to IPV in patient meetings, (2) training through the use of a virtual patient case tailored to health professionals and (3) a combination of (1) and (2) earlier. Preintervention (baseline) and postintervention measurements of the health professionals’ enquiry and identification of patients exposed to IPV will be used to explore the effect of the interventions. Focus group interviews with the participating health professionals will be used as a qualitative method, applying thematic analysis, to explore which intervention they perceive as most effective in increasing their ability to identify victims of IPV.
Data analysis will focus on a comparison of pre- and post-measurements regarding the number of patients asked about and identified patients in each intervention arm that have been or are exposed to IPV. Measurements will be carried out per care unit at the group level. Qualitative data from focus group interviews will be analysed using thematic analysis.
All participants will sign a written consent form and the study has been approved by the Swedish Ethical Review Authority (Dnr 2023-03399-01). The study will be conducted according to good clinical practice and the Declaration of Helsinki. The results of this study will increase knowledge about how identification of violence in close relationships can be improved in the clinical setting through publications in peer-reviewed journals and presentations at national and international scientific conferences.

The gig economy is a promising arena to reduce unemployment and provide other benefits such as the opportunity to earn supplemental income. Like all other forms of work, the gig space also presents occupational health issues for those working in it. This proposed review is aimed at identifying and describing the common occupational health outcomes reported within this workforce; second, to examine the risk factors that contribute to the development of these health issues; and third, to assess the interventions and support systems currently in place to promote the occupational health of gig workers.
A systematic review will be undertaken according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (2009). A search from 2015 to 2025 will be conducted on four global databases (Web of Science, SCOPUS, Academic Source Complete and Business Source Complete). Only records in English, full text and peer-reviewed journal articles will be included. Book chapters, thesis, reports and systematic reviews will be excluded. The Joanna Briggs Institute Critical Appraisal Tools will be used to assess the methodological rigour of various studies prior to inclusion for the final analysis. The extracted data will be synthesised using a narrative synthesis approach, integrating findings from both quantitative and qualitative studies.
This research is exempt from ethics approval because the work will be carried out on published documents. We will disseminate this protocol in a related peer-reviewed journal.

Atopic dermatitis (AD) is a chronic inflammatory skin condition that impairs the quality of life of affected paediatric patients and their families. Dupilumab, an antagonist of the shared alpha chain subunit of the cytokines interleukin-4 and interleukin-13, has revolutionised the management of moderate-to-severe AD by effectively targeting type 2 inflammation. However, live attenuated vaccines, including live attenuated influenza vaccines (LAIVs), are contraindicated during dupilumab therapy owing to limited safety data. This restriction poses challenges to immunisation strategies, particularly in paediatric populations. This study aims to evaluate the safety and efficacy of LAIV in paediatric patients with AD undergoing dupilumab therapy.
This multicentre, prospective, single-arm, open-label trial will enrol 50 paediatric patients aged 2–18 years with AD undergoing dupilumab treatment. The participants will receive intranasal LAIV, followed by a 25-week observation period after vaccination. The primary outcome is the proportion of participants with a four-fold or greater increase in haemagglutination inhibition titres against influenza strains A(H1N1), A(H3N2) and B at 4 weeks post vaccination. The secondary outcomes include the incidence of influenza and systemic or local adverse events, such as injection site reactions, fever and other influenza-like symptoms observed within 4 weeks of vaccination. Exploratory endpoints include the evaluation of immunosuppressive markers such as neutrophil counts, lymphocyte subsets and serum immunoglobulin G levels. Safety analyses will assess the frequency of each adverse event, whereas efficacy analyses will focus on immunogenicity and influenza incidence during the 25-week follow-up period. This study aims to provide critical safety and immunogenicity data to guide immunisation strategies in biologically treated paediatric patients with AD.
This study complies with the principles of the Declaration of Helsinki and received ethics approval from the Institutional Review Board of Chiba University Hospital as a specified clinical trial. Informed consent and assent will be obtained as appropriate based on the participants’ ages. These findings will be disseminated through peer-reviewed journals and scientific conferences to inform clinical vaccination strategies for biologically treated populations.
