Each year, millions of people experience recurrent diverticulitis episodes. Elective sigmoid colon resection reduces the risk of recurrence, but The American Society of Colon and Rectal Surgeons recommends individualising surgical decisions based on the impact of the condition on a patient’s quality of life (QoL). However, no threshold for QoL impairment has been established to guide decision-making, and evidence comparing elective colectomy with medical management in terms of QoL limitation is limited. To address these gaps and to guide treatment decision-making, we designed the Comparison of Surgery and Medicine on the Impact of Diverticulitis (COSMID) trial.
The COSMID trial is a large, pragmatic randomised trial including patients with QoL-limiting diverticulitis that aims to determine if partial colectomy is superior to medical management and explore subgroups that are more likely to respond to each treatment.
COSMID will recruit 250 English-speaking and Spanish-speaking adults with imaging-confirmed and QoL-limiting diverticulitis (defined using a modified diverticulitis-related QoL survey). Participants are randomly assigned to undergo elective partial colectomy or receive comprehensive medical management (eg, selected from options including fibre, probiotics, mesalamine and rifaximin). A total of 100 patients who decline randomisation but consent to follow-up will be included in a parallel observational cohort. The primary outcome is the time-averaged score of the Gastrointestinal Quality of Life Index at 6, 9 and 12 months after randomisation. Secondary outcomes include clinical adverse events, healthcare utilisation, recurrent episodes of diverticulitis and additional patient-reported outcomes like the Diverticulitis Quality of Life instrument, decisional regret and work productivity. Exploratory analyses aim to identify differential treatment effects based on patients’ characteristics.

Crohn’s disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract distinguished by progressive bowel damage with a risk of structuring and penetrating complications. It is characterised by focal or segmental transmural inflammation that disrupts intestinal mucosal integrity and favours the development of abscesses and fistulas. Perianal fistula develops in 13%–39% of patients with CD. Their care is difficult but improves with medical and surgical treatment to preserve anal continence and avoid a maximum proctectomy. Combined treatment with seton placement and concomitant anti-TNF (infliximab, adalimumab) allows wound healing in 40%–70% of cases. The currently available treatments are not curative and fail to provide a long-term resolution. The injection of adipose stromal cells is currently being evaluated in clinical studies for repair-damaged tissues in various diseases (limb ischaemia, osteoarthritis, systemic sclerosis, etc). Immunoregulatory and anti-inflammatory properties of AdMSC (adipose-derived stroma/stem cells) are responsible for accelerating healing and represent an innovative approach for treating perianal fistulas associated with CD.
This phase I/IIa study is designed to assess the treatment of complex perianal fistulas linked with CD after failure of conventional treatment by injection of AdMSC (CellReady) into the fistula. Two doses of associated AdMSC will be tested for a dose escalation (5x107 and 10x107 cells) and injected into the wall of the fistula. Those eligible for inclusion include patients with controlled luminal CD characterised by a Harvey-Bradshaw score below or equal to eight and diagnosed on clinical, endoscopic, histological and/or radiological criteria, a colonoscopy dating back less than 1 year without ulcer in the rectum and presence of complex chronic perianal fistula with a maximum of two internal ports and three external ports. All patients must have social security insurance or equivalent social protection. The aim of this study is to determine the optimal dose corresponding to maximum efficacy 6 months after injection of cells with a treatment-related adverse event rate of 20%.

Living with epilepsy, especially drug-resistant epilepsy (DRE), imposes several challenges for people diagnosed with the condition. These challenges include the physical and mental implications of epilepsy on both caregivers and patients with epilepsy. For the more than 120 000 individuals living with this neurological disorder in the Netherlands, along with their families, daily activities become hazardous, limited and costly, significantly affecting their health-related quality of life (HRQoL). As data on the burden of epilepsy in the Netherlands are lacking, studies attempting to capture the impact of epilepsy on individuals, caregivers and society are needed to enhance understanding and help address the burden of epileptic seizures.
The study is part of the AIM@EPILEPSY project. The project aims to develop a planning suite enabling cost-saving, minimally invasive treatment for epilepsy. By surveying 330 people with epilepsy and an anticipated sample of 150–200 informal caregivers across the Netherlands, using standardised questionnaires focusing on associated societal costs and the impact on HRQoL, this bottom-up, prevalence-based prospective study aims to understand the societal burden of DRE in the Netherlands. The data will be collected at 0, 3, 6 and 12 months of follow-up. The study results will describe the economic impact of epilepsy, focusing on cost-of-illness () and HRQoL (utilities) in the Netherlands.
The proposed study was approved by the Maastricht University Medical Ethics Review Committee (Approval reference: FHML-REC/2024/067/Amendment/2024_16). The result of the study is planned to be published in a peer-reviewed journal and presented at international and local scientific conferences.
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.
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.
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.
