Principal investigators experience of COVID-19 therapeutic clinical trials in Japan: a qualitative study

Objective
During the COVID-19 pandemic, many clinical trials were conducted to identify effective COVID-19 therapeutics. However, while a large amount of resources was invested and significant numbers of patients participated, this did not necessarily have an impact on clinical practice. To face these issues, initiatives such as the 100 Days Mission have been set out globally. Yet, limited data exist on the context surrounding the implementation of clinical trials at a national level during a health emergency. The study explored experiences and perceptions of principal investigators in conducting clinical trials for COVID-19 therapeutics in Japan.

Design
A qualitative study was conducted using semistructured interviews. The obtained data were inductively analysed using thematic analysis.

Setting and participants
We interviewed 15 principal investigators between September and November 2022 who conducted investigator-initiated clinical trials on the development of COVID-19 therapeutics in Japan.

Results
Three themes were generated: structural barriers, fragmented efforts and limited evidence generation. Structural barriers and fragmented efforts comprised four subthemes: individual, institutional, interinstitutional and policy/regulatory levels. Structural barriers at all levels included (1) limitations of individual capabilities, (2) the double burden of clinical practice and research, (3) inefficient interinstitutional collaboration and (4) regulatory frameworks and available resources that interrupt stakeholders’ actions, leading to limited evidence generation despite the fragmented efforts of principal investigators and other stakeholders.

Conclusions
This study illustrated that the efforts of Japanese principal investigators did not necessarily pay off in identifying therapeutics. A strategic and systematic approach for an improved national clinical trial ecosystem must be sought during the interpandemic period to overcome structural barriers in harmonisation with the global stakeholders.

Presentato in Senato il Position Paper sui PDTA per amiloidosi da transtiretina  [Cardio]

Un paziente con amiloidosi cardiaca da transtiretina (ATTR) oggi in Italia può ricevere diagnosi e cure molto diverse a seconda della Regione in cui vive. Eppure, questa malattia rara, spesso sottovalutata e diagnosticata troppo tardi, necessita di un percorso di cura rapido, personalizzato e multidisciplinare.
Per rispondere a questa sfida, Bistoncini Partners ha realizzato, con il contributo non condizionante di Pfizer, il Position Paper: “L’importanza dei PDTA personalizzati per la gestione del paziente con Amiloidosi da Transtiretina”, che viene oggi presentato nel corso di una conferenza stampa promossa dalla Senatrice Elena Murelli

Developing a core outcome set for gender-affirming healthcare in transgender and gender diverse adults in Sweden using the Delphi approach: a study protocol

Introduction
Despite an increasing amount of research related to gender-affirming treatment (GAT) outcomes among transgender and gender-diverse (TGD) people (ie, people who experience discomfort or distress in the misalignment between their gender and sex assigned at birth) in recent years, the evidence base for current recommendations is suboptimal. One contributing factor is the heterogeneity in the outcomes and outcome measures used. This study seeks to address this challenge by developing a foundational core outcome set (COS) to be used for TGD adults receiving GAT in Sweden.

Methods
Recommendations from the Core Outcome Measures in Effectiveness Trials initiative will be used to address this aim in four phases. Phase 1, an umbrella review of peer-reviewed literature and international guidelines in GAT will be conducted to identify relevant outcomes. In phase 2, we will solicit input from TGD individuals through the review of patient and interest organisations’ reports and an anonymous survey to identify outcomes of personal significance. In phase 3, using the Delphi method, 2–3 rounds of assessment will be conducted where researchers, healthcare professionals, policy-makers and TGD adults rate the identified outcomes by perceived importance. In phase 4, a consensus meeting will convene representatives from all stakeholder groups to finalise the COS.

Analysis
The results of this study will consist of a COS for GAT regarding TGD adults in Sweden. Participant survey responses will be evaluated using interpretive analysis to identify core outcomes. During each of the Delphi rounds, Likert-type scale ratings will be aggregated for outcomes to advance or be eliminated in each round.

Ethics and dissemination
The study has received ethical approval by the Swedish Ethical Review Authority (Umeå medicine department, Registration number: 2024-04672-01). The results of this study will be published open-access and disseminated through TGD interest organisations and a Swedish research network for gender dysphoria.

Association between loneliness and depression, anxiety and anger during the COVID-19 pandemic: a nationwide population-based survey

Objectives
This study aims to determine the association between loneliness and depression, anxiety and anger with a representative sample of the general population in Korea, which are the most prevalent mental health problems during the pandemic.

Design
Cross-sectional study.

Setting
National survey across all 17 provinces in South Korea between December 2021 and January 2022.

Participants
We conducted a national survey on 2699 participants aged 19–84 years using proportional stratified sampling. Using the UCLA Loneliness Scale and standardised questionnaires for depression (Patient Health Questionnaire-9), anxiety (Generalised Anxiety Disorder-7) and anger (Patient-Reported Outcomes Measurement Information System-Anger), we explored the prevalence and association of loneliness with these mental health outcomes.

Primary and secondary outcome measures
Primary outcomes included the prevalence and co-occurrence of depression, anxiety and anger across different levels of loneliness.

Results
Of total, 20.7% and 2.1% experienced moderately high and high levels of loneliness, respectively. Among participants with high levels of loneliness, 11.8%, 5.9% and 11.8% had depression, anxiety and anger, respectively, and 28.7% of them had depression, anxiety and anger together. The adjusted prevalence of depression was 0.2 (95% CI 0.0 to 0.5), 8.2 (95% CI 6.7 to 9.7), 31.3 (95% CI 27.4 to 35.3) and 63.5 (95% CI 50.1 to 76.8) for low, moderate, moderately high and high levels of loneliness, respectively. Similarly, increased adjusted prevalence of anxiety and anger was observed ㅈwith higher levels of loneliness.

Conclusions
Lonely people have a higher risk of depression, anxiety and anger. Identifying individuals who may be vulnerable to loneliness is important for early intervention.

A multicentre, randomised controlled clinical trial evaluating the effect of the adsorptive filter oXiris on haemodynamics in abdominal septic shock patients requiring continuous renal replacement therapy (Oxiris for Abdominal SEptic Shock study)

Introduction
Septic shock-associated acute kidney injury (AKI) is known to carry a poor prognosis. The present study aims to evaluate the effect of absorptive blood purification on haemodynamic status and clinical outcomes in patients with septic shock-associated AKI.

Methods and analysis
This multicentre, randomised controlled trial will evaluate an adsorbent filter (oXiris) in patients with abdominal septic shock requiring continuous renal replacement therapy (CRRT). The study plans to recruit 192 participants from intensive care units, who will be randomly assigned to either the intervention group (oXiris set) or the control group (ST 150 set). The primary endpoint is the reduction in norepinephrine equivalence following the initiation of CRRT. Key secondary endpoints include changes in cardiac index and systemic vascular resistance index, as measured by pulse indicator continuous cardiac output, following CRRT initiation, as well as overall survival and kidney recovery rates.

Ethics and dissemination
The study will be conducted in accordance with the Declaration of Helsinki and Good Clinical Practice. The Ethics Committee of Shanghai Jiaotong University School of Medicine, Renji Hospital (no. LY-2024–082-B) approved this study on 27 May 2024. The results will be published in peer-reviewed journals and presented at international conferences.

Assessing the experimental EuroQol toddler and infant populations (EQ-TIPS) descriptive system: a protocol integrating discrete choice experiment (DCE) surveys in instrument development

Introduction
The experimental EuroQol Toddler and Infant Populations (EQ-TIPS) instrument is currently under development as a health-related quality of life (HRQoL) measure for toddlers and infants aged 0–36 months. Using this protocol, researchers can conduct surveys with discrete choice experiments (DCEs) that examine the key properties of HRQoL instruments, specifically whether severity aligns with preferences across each attribute and the extent to which attributes influence choices. To demonstrate this protocol, we will conduct two waves of DCE surveys using different choice tasks and a common scenario (a 1-month health episode for a 1-year-old child).

Methods and analysis
In the first wave (a general population sample of 400 Australian adults; 14 kaizen tasks each), respondents will view a single EQ-TIPS-five-level (v3.0) profile for each task and be asked to make a series of choices that sequentially alleviate the child’s health problems. Using this exploratory evidence, we will assess whether EQ-TIPS severity aligns with preferences and the extent to which each attribute level influences choices (ie, main effects). In the second wave (1000 Australian adults; 28 paired comparisons), respondents will see two EQ-TIPS profiles for each task and be asked to choose between them. Using this confirmatory evidence, we will compare the main effects and their uncertainty by wave. For each DCE, we will estimate a main-effects conditional logit model and test for differences in effects using cluster bootstrap techniques. As sensitivity analyses, we will evaluate the effects of task sequence, attribute order and sample size on uncertainty in each wave.

Ethics and dissemination
The independent review board at Includovate evaluated the application for ethical clearance and approved the study on 19 February 2025. To disseminate our findings, we will prepare multiple manuscripts for publication in peer-reviewed journals and present highlights at scientific meetings, such as the EuroQol Plenary Meeting and the International Academy of Health Preference Research.

Understanding Predictors of Lifelong Initiation and Follow-up Treatment for adolescents and youth living with HIV (UPLIFT): an integrated prospective cohort in Eastern Cape, South Africa

Purpose
Adolescents living with HIV (ALHIV) are a priority population for achieving global HIV prevention and treatment targets but experience poorer outcomes than adults. Long-term follow-up is essential to understand their transition into adulthood. By linking self-reported survey data with routine laboratory records, we established a social science clinical cohort of ALHIV South Africa’s Eastern Cape to explore factors shaping their long-term health and well-being.

Participants
Eligible participants were adolescents who were part of a three-wave quantitative cohort of ALHIV and not living with HIV (2014–2018) and had consented (adolescent and caregiver) to having their self-reported interviews linked with routine health records (n=1563). Adolescents were recruited into the existing three-wave cohort through clinic and community-based methods (97% enrolment, >90% retention over three waves). Between 2019 and 2022, we abstracted laboratory test records from the National Health Laboratory Services database for all eligible participants, with matching based on demographic variables. Individuals with at least one HIV-related record form our ‘lifelong social science cohort’, a total of 956 ALHIV (852 of 1107 ALHIV and 104 of 456 HIV-uninfected).

Findings to date
A total of 32 886 laboratory test records from 2004 to 2023 were matched through three rounds of data extraction, using iteratively refined record-linking searches. Most records were viral load (8864) and CD4 count (6801) results, with a median of 10 (IQR: 7–14) and 8 (IQR: 5–11) tests per matched adolescent, respectively. Overall, 956 of 1563 adolescents (61%) were successfully linked to laboratory data, including 852 of 1107 (77%) ALHIV. Analysis of the matched cohort survey-laboratory data provided several insights. Self-reported antiretroviral therapy adherence was strongly associated with viral suppression, even after adjusting for covariates. The strongest predictors of suppression were not reporting missed doses in the past 3 days, past week and not missing clinic appointments in the past year. Among adolescent girls and young women living with HIV, access to safe and affordable facilities, and kind and respectful staff were associated with a higher likelihood of multiple improved HIV-related outcomes, including viral suppression. Exposure to sexual and intimate partner violence predicted worse viral load outcomes among adolescents.

Future plans
This integrated prospective cohort provides an opportunity to characterise long-term HIV treatment outcomes among ALHIV in Africa. We will investigate how individual, familial, community and healthcare experiences in childhood, and adolescence shape these outcomes. Since the COVID-19 pandemic happened during the period of matched data, we will also investigate the potential effect of the COVID-19 pandemic on adolescent HIV treatment outcomes, with potential subgroup analyses for individuals with available COVID-19-related results.

Investigating the relationship between Pfkelch13 mutations and response to artemisinin-based treatment for uncomplicated falciparum malaria: a protocol for a systematic review and individual patient data meta-analysis

Introduction
Artemisinin-based combination therapies (ACTs) remain the WHO-recommended treatment for uncomplicated Plasmodium falciparum malaria. However, the emergence and spread of artemisinin resistance (ART-R) threatens ACT efficacy. ART-R is phenotypically expressed as delayed parasite clearance, which can facilitate ACT partner drug resistance. ART-R has been causally linked to specific mutations in the Pfkelch13 gene.

Methods and analysis
The systematic review and associated meta-analysis aim to determine the correlation between Pfkelch13 (alleles present in the Kelch13 gene region of the P. falciparum parasite) genotypes and clinical and parasitological response to ACTs from a globally representative data set pooling individual patient data (IPD) from eligible published and unpublished studies. The eligibility criteria include Pfkelch13 genotyping results at baseline complemented by individually linked parasitological and clinical assessments following artemisinin-based treatment. The data will be curated, standardised and analysed using this proposed statistical analysis plan (SAP), adhering to PRISMA-IPD (PRISMA, Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Our SAP will apply hierarchical modelling to assess the effect of the P. falciparum parasite Pfkelch13 mutations on parasite clearance half-life and therapeutic efficacy across different regions. This will include study sites as random effects in the model and potential predictors such as age, sex, baseline parasite load and other potential effect modifiers as fixed effects. This analysis will enhance the understanding of the influence of Pfkelch13 mutations on malaria treatment outcomes.

Ethics and dissemination
Data were obtained with informed consent and ethical approvals from the relevant countries and were pseudonymised before curation in the Infectious Diseases Data Observatory (IDDO)/WorldWide Antimalarial Resistance Network (WWARN) repository. Data ownership remains with contributors. This IPD meta-analysis met the Oxford Tropical Research Ethics Committee criteria for waiving ethical review, as it is a secondary analysis of existing pseudonymised data. The resulting peer-reviewed publication and conference proceedings will help strengthen and enhance the efficiency of ART-R surveillance and response and support policy decisions.

Multisectoral coordination during the COVID-19 pandemic: practices, challenges and recommendations for future preparedness–a systematic literature review protocol

Introduction
The COVID-19 pandemic amplified the need for robust multisectoral coordination; yet the specific mechanisms, benefits and challenges of such collaboration particularly in low- and middle-income countries (LMICs) remain poorly synthesised. This review aims to delineate the key elements, benefits, challenges and improvement strategies of multisectoral coordination during COVID-19 and to compare patterns between LMICs and high-income countries (HICs).

Methods and analysis
Eligible studies will include empirical qualitative, quantitative or mixed-methods research published in English between 1 January 2020 and 15 August 2024 that examines formal coordination mechanisms (eg, task forces, public-private partnerships, inter-agency committees) within the context of COVID-19. Searches will be conducted across PubMed, EBSCOhost, Emerald Insight, Google Scholar and selected grey-literature repositories. Citation chaining will be employed to identify additional sources.
Two reviewers will independently screen all records using Covidence, applying pre-piloted eligibility criteria to 5% of citations and proceeding only if inter-rater reliability achieves ≥0.70. Data will be extracted into a Consolidated Framework for Implementation Research (CFIR)-informed template. Qualitative data will be analysed through framework synthesis, structured by the five CFIR domains. Quantitative data will be narratively summarised and, where outcomes are sufficiently similar across at least two studies, synthesised using a fixed-effect model.
Risk of bias will be assessed using Critical Appraisal Skills Programme for qualitative and Risk Of Bias In Non-randomised Studies of Interventions for non-randomised studies. Studies with serious or critical risk will be excluded from pooling. Subgroup analyses (LMIC vs HIC), sensitivity analyses (model and risk) and confidence grading using Confidence in the Evidence from Reviews of Qualitative Research and Grading of Recommendations, Assessment, Development and Evaluations will be conducted.

Ethics and dissemination
No primary data will be collected; thus additional Research Ethics Committee approval is unnecessary. The results will be disseminated via open-access publication, conference presentations and policy briefs for Nairobi County health stakeholders.
