Existing psychological and pharmacological interventions for young people at ultra-high risk (UHR) for psychosis have shown benefit in at least delaying the transition to psychosis, but they have limited benefit for comorbid disorders or social dysfunction, which are prominent for those at UHR. We developed a moderated online social therapy platform (named Momentum) including: (1) transdiagnostic therapeutic interventions targeting social functioning, depression, generalised anxiety and social anxiety; (2) a moderated, peer-led online community and (3) specialised human support from clinicians, career consultants and peer workers. The aim of this trial is to determine whether, in addition to treatment as usual (TAU), Momentum, a 12-month digital intervention, informed by the complex intervention framework, is superior to 12 months of TAU in improving social functioning in UHR young people.
The study design is a prospective, parallel group, rater-masked randomised controlled trial. We will recruit young people aged 14–27 years, meeting one or more UHR for psychosis criteria. Participants are randomly assigned to the condition using randomly permutated blocks with a 1:1 allocation ratio. Participants are stratified by age (

Neutropenic fever (NF) has a crude mortality rate of 3–18%. International guidelines recommend that all patients with NF receive ultrabroad-spectrum antibiotics (UBSAs) within 1 hour of emergency department (ED) registration. However, over 70% patients presenting to hospital with suspected NF (sNF) cannot access absolute neutrophil count (ANC) result within 1 hour, do not have NF and do not require UBSAs. In ED and hospitalised patients with sNF, we hypothesise that the ASTERIC protocol effectively and safely reduces the use of UBSAs compared with standard care alone.
This pragmatic, parallel, multicentre, type 1, hybrid effectiveness-implementation, stepped-wedge, before-and-after, cluster randomised controlled trial aims to evaluate whether antibiotic prescribing can be safely reduced through implementing a multifaceted antibiotic stewardship intervention (ASTERIC) in adult patients with sNF presenting to EDs. The sNF was defined as a fever with a single oral temperature of ≥38.3°C (101°F) within 24 hours before ED registration or a temperature of ≥38.0°C (100.4°F) sustained over a 1-hour period, following last chemotherapy or targeted therapy within 6 weeks for any solid tumour, or in any period following therapies against leucaemia, lymphoma, myelodysplastic syndrome, aplastic anaemia, multiple myeloma or recipient of HSCT. The study will involve eight hospitals in Hong Kong with variable baseline practice. We will include 704 adult patients (352 patients in pre-implementation and post-implementation periods, respectively) with sNF (tympanic temperature ≥38.3°C) and 48 staff participants (6 staff participants in each hospital). Healthcare professionals will receive a multifaceted stewardship intervention consisting of risk assessment tools, fast-track ANCs, a decision tool for patient management and antibiotic use, supported by an educational package and staff interaction programmes (ASTERIC protocol). Patients’ blood ANC, and cancer therapy and chronic illness therapy scores will be measured. The RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) and Proctor conceptual frameworks will be followed for evaluation of implementation. The main outcome measures are the mean total dose of UBSAs prescribed in 7 days and serious adverse events at 30 days. Data analysis will incorporate intention-to-treat, per-protocol and as-treated analyses for service outcomes (effectiveness, safety, quality of life assessments and cost-effectiveness) and mixed methods for implementation outcomes, informed by the Theoretical Domains Framework. We expect that the study results will inform health policy with improvement in hospital services in treating stable sNF, evidenced by improved safe antibiotic stewardship, early antibiotic de-escalation and reduced costs and length of stay.
The institutional review boards of all study sites approved this study. This study will establish the ASTERIC protocol safely improves antibiotic stewardship and clinical management in adult patients with sNF. We will disseminate the findings through peer-reviewed publications, conference presentations and educational activities. All patients with sNF will be influenced by the new protocol which is agreed at hospital level. Randomisation is at hospital level, not patient level. Patient consent is sought for follow-up and data access, not for treatment. Staff consent is sought for interviewing.
Although low-density lipoprotein cholesterol (LDL-C) is established as the primary cardiovascular disease (CVD) risk factor, some individuals with LDL-C within desirable limits still develop coronary artery disease (CAD). Lipoprotein(a) (Lp(a)) has emerged as a genetically determined independent risk factor for CVD. This study aims to investigate Lp(a) by determining its association with coronary artery stenosis severity, identifying its ethnic-specific genetic determinants and assessing its relationship with an energy-dense dietary pattern.
The PUTRA-CV study is a 3-year, multicentre, case-control observational study involving adult patients who have undergone coronary angiography. The primary outcome is the association between Lp(a) levels and the severity of angiographic CAD (assessed by Gensini or Syntax score). Secondary outcomes include the frequencies of Lp(a)-associated single nucleotide polymorphisms (SNPs) (rs10455872 and rs3798220) and the association between dietary patterns and Lp(a) levels. Lp(a) will be measured using a particle-enhanced immunoturbidimetric method, and SNPs will be genotyped using high-resolution melting. Dietary intake will be assessed using a validated semiquantitative food frequency questionnaire. Data will be analysed using SPSS. Descriptive statistics will be used to summarise population characteristics. Bivariate analyses will use chi-square (2), independent t-tests or Mann-Whitney U tests as appropriate. The independent association between Lp(a) and coronary artery stenosis severity will be determined using multivariable logistic regression, adjusting for confounders. Empirically driven dietary patterns will be derived using reduced rank regression, and their association with Lp(a) will be assessed. For genetic analysis, allele frequencies of the LPA SNPs rs10455872 and rs3798220 will be calculated and compared between cases and controls.
