Phasix mesh is a fully resorbable synthetic mesh for use in clean and contaminated ventral incisional hernia repairs. Long-term absorbable Phasix mesh appears to be a safe and promising device in incisional hernia repair, with low recurrence rates; however, data on long-term complications after surgery, particularly after the resorption period of the mesh, are scarce.
This protocol describes a study of several European registries on the use of a Phasix mesh in incisional hernia repair. The primary endpoint of the study is long-term complications at 2–5 year follow-up after mesh implantation, with secondary endpoints including hernia recurrence and complications during short-term follow-up.
Ethical approval was not required for this protocol as the study is based on anonymised registry data collected with prior patient consent in each registry. Each participating registry has its own ethical approval process, and this study will adhere to those regulations. The results will be disseminated through peer-reviewed publications and conference presentations.
The intestinal microbiota of people with Parkinson’s disease (PwP) differs significantly from that of healthy individuals. Given that altered microbiota may play a role in the pathogenesis of Parkinson’s disease, faecal microbiota transplantation (FMT) has been proposed as a potential therapeutic approach. However, the efficacy of FMT in improving motor symptoms in PwP has been inconclusive in some pilot randomised controlled trials (RCT). Previous RCTs on PwP employed simple FMT, but our modified approach—pretreatment with antibiotics before FMT (A-FMT)—has been shown to improve the engraftment rate of given species and the beneficial effects of FMT. This study aims to evaluate the efficacy and safety of A-FMT for PwP, particularly in those with motor fluctuations.
This study is a randomised, double-blind, placebo-controlled, parallel-group study with an 8-week observation period following a single A-FMT. Thirty clinically established PwP with prominent motor fluctuation episodes will be randomised 1:1 to FMT or placebo. Participants in both groups will receive antibiotic treatment prior to colonoscopy for FMT or placebo treatment. Primary and secondary endpoints will include subjective and objective evaluations of motor and non-motor symptoms and will be evaluated before and after antibiotic treatment and at 4 and 8 weeks after the procedure. Exploratory endpoints will include blood and faecal sample analyses, advanced brain MRI and pharmacokinetic assessment of levodopa concentrations during a levodopa challenge test.
This study has been approved by the ethical committee of Juntendo University in August 2024 (J24-005) and will be conducted in accordance with the Declaration of Helsinki, the Japan Ministry of Health, Labour and Welfare Clinical Trials Act and related laws and regulations. All patient data will be anonymised to protect privacy and used solely for study purposes. Results will be published in academic journals and presented at conferences.

Surgical site infections (SSI) and surgical site complications (SSC) significantly impact surgery outcomes, increasing hospital stays and mortality rates, and negatively affecting patients' quality of life. Closed-incision negative pressure therapy (ciNPT) emerged as a prophylactic strategy to reduce these complications. However, its applicability across different surgical procedures remains unclear. A scoping review was conducted to synthesise the available evidence on the use of ciNPT in different surgical contexts. A multidisciplinary panel of experts from different surgical specialties was assembled to identify patient risk factors for SSCs specific to each modality. Surgical procedures were categorised based on anticipated SSC rates and the impact of SSI. A decision diagram was finally developed, providing tailored recommendations for ciNPT use according to individual surgical circumstances. The findings of the review indicate that ciNPT effectively reduces SSI and SSC in most surgical procedures. Key patient-related factors influencing outcomes, such as age, obesity, and malnutrition, were outlined. Additionally, a specialty-based list of surgical procedures was compiled, specifying whether ciNPT is recommended, not recommended, or conditionally recommended based on specific criteria. This study underscores the benefits of ciNPT and provides a comprehensive guide to its application across several surgical specialties, aiming to optimise patient management and inform clinical practise.
Traumatic brain injury (TBI) often causes permanent neurological dysfunction. Although no medication has been validated yet to prevent secondary injury of brain tissue, recent animal studies have reported that perampanel, a glutamine receptor antagonist, could improve the neurological functions of animals with TBI by mitigating the abnormal calcium influx and cell death around the site of primary injury. The present study aims to elucidate the efficacy of perampanel administration in improving the neurological function of patients with TBI.
The perampanel for alleviation of secondary injury in TBI trial is a multicentre, phase-II, open-label randomised controlled trial targeting patients with mild-to-moderate TBI. This trial will include adult TBI patients with a Glasgow Coma Scale score of 9–14 from five tertiary centres. Patients with epilepsy as a comorbidity, delayed presentation of symptoms (>24 hours after injury) or Injury Severity Score of ≥25 will be excluded. The study participants will be randomly assigned to either the perampanel group (2 mg/day) or the control group (fosphenytoin administered at a dose of 15–18 mg/kg/day, followed by 5–7.5 mg/kg/day of fosphenytoin). In both groups, the medication will be initiated within 12 hours of the TBI diagnosis and continued for 7 days. The antiepileptic drugs can be increased, changed or added as necessary if early post-traumatic seizures are observed. The primary outcome is favourable neurological outcome, defined as a Glasgow Outcome Scale Extended score of ≥5 at 90 days after the TBI diagnosis, which will then be compared between the groups through an intention-to-treat analysis.
The present study has been approved by the Certified Review Board of Keio at the principal institution (approval number: N20240004). Written informed consent will be obtained from all participants or their legal representatives. The results will be disseminated via publications and presentations.
