To develop survey items for a national patient registry on Long COVID using a modified Delphi process.
This study was based on a modified Delphi process involving three rounds of anonymous, online surveys to develop consensus on and prioritise survey elements to be included in a minimum dataset for use in a national patient registry in Canada. Initial Long COVID items were identified through an environmental scan of the literature.
This study focused on healthcare systems in Canada and was conducted online.
A panel of 52 experts (patients, caregivers, clinicians and researchers) participated in all three rounds of the online survey. These participants were recruited through the Long COVID Web network and word of mouth.
In total, 243 survey elements related to care, quality of life and symptoms were included in round 1 of the survey. 200 reached consensus and moved to round 2 with two additional elements being developed based on open-ended responses. In round 2, participants ranked these survey elements and 34 advanced. In round 3, 33 survey elements met the threshold of consensus with one added a priori. The 33 survey elements were then used to develop a Long COVID minimum dataset, which consists of 48 items.
The findings affirm broad consensus for collecting data related to fatigue, post-exertional malaise, cardiovascular issues, respiratory problems and cognitive issues. This highlighted the desire for quality-of-life indicators and information related to care utilisation, quality and access.

IntroductionIn Togo, the syndromic approach is used for the diagnosis and management of sexually transmitted infections (STIs). The aim of this study was to evaluate the syndromic approach for diagnosis of STIs among female sex workers (FSW) in Lomé, Togo.
MethodsA cross-sectional study was carried out from September to October 2023 among FSW in Lomé (Togo). FSW aged 18 years and above were included. A gynecological examination was performed for syndromic diagnosis, and the Xpert® CT/NG were used to screen vaginal swabs for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG). The performance (predictive values) of the syndromic approach to STI diagnosis was evaluated using the Xpert® CT/NG test as the gold standard.
ResultsA total of 357 FSW were recruited. The median age of FSW was 32 years (IQR: [26–40 years]) and 8.2% had attained a higher level of education. The prevalence of syndromic STI among FSW was 33.3%. Vaginal swabs were positive for CT (8.4%) and NG (8.7%), with a prevalence of bacterial STIs (CT and/or NG) of 14.3%. The syndromic approach to STI diagnosis demonstrated a positive predictive value of 24.3%.
ConclusionThe prevalence of STIs is relatively high among FSW in Lomé. According to this study, the diagnosis of STIs using the syndromic approach has limited relevance. National STI screening and management policies urgently need to be rethought, incorporating recent technological advances.
This research paper presents a study protocol for an exploratory clinical trial evaluating the safety and potential efficacy of autologous peripheral blood mononuclear cell (PBMNC)-loaded injectable cell scaffold (ICS-001) for angiogenic therapy in chronic limb-threatening ischaemia (CLTI). CLTI, the advanced stage of peripheral artery disease, presents significant therapeutic challenges.
Angiogenic therapy using ICS-001 with PBMNCs—a novel approach designed to enhance local cell retention and promote neovascularisation—will be explored. The study will address the pathophysiology of CLTI, the limitations of current treatments and the rationale for cell-based therapies, alongside the clinical trial design for evaluating the safety and efficacy of ICS-001. We hypothesise that ICS-001 will improve ulcer healing and reduce ischaemic rest pain in patients with CLTI. This paper outlines the methodology, including patient selection, CD34+ cell mobilisation, scaffold preparation, injection protocols, clinical assessments, data collection and safety monitoring. The anticipated results, discussion and conclusion will offer insight into the clinical significance and potential impact of ICS-001 as a pioneering angiogenic therapy for CLTI.
The institutional review boards of all participating hospitals approved this study protocol (latest version V.6.0, 5 June 2025). Final data will be made publicly available. A report detailing the study results will be submitted for publication in an appropriate peer-reviewed journal.

Occupational exposure to polycyclic aromatic hydrocarbons (PAHs) has been associated with adverse health effects, yet evidence on the cognitive consequences of such exposure remains fragmented and has not been systematically synthesized across occupational groups. This protocol outlines a systematic review that will examine the relationship between occupational PAH exposure and cognitive impairment across eight predefined occupational categories. Relevant studies will be identified through electronic searches of major databases, including PubMed, Web of Science, Scopus, Embase, ProQuest, PsycINFO, CINAHL, the Cochrane Library, and Google Scholar. Eligible studies must assess PAH exposure in occupational settings and evaluate cognitive outcomes using validated instruments, with domain-specific neuropsychological tests prioritized as primary outcomes and global screening tools (e.g., MoCA, MMSE) included as supportive outcomes. Both observational and comparative study designs will be considered. Titles and abstracts will be screened by two independent reviewers, and full texts of potentially eligible articles will be assessed using predefined criteria. Data will be synthesized narratively, with contingency meta-analysis conducted where sufficient comparable data are available and heterogeneity is acceptable. Prespecified subgroup analyses will be undertaken by occupational category, biomarker, cognitive domain, and exposure context, with meta-regression considered if an adequate number of studies are identified. Risk of bias will be assessed using JBI tools at the study level and ROBIS at the review level, with planned sensitivity analyses. The review will consolidate current evidence on PAH-related cognitive outcomes across occupational groups, including under-studied populations such as wildland firefighters, and will inform occupational health policy, workplace screening initiatives, and future research aimed at safeguarding cognitive health in exposed populations.
