Peri-procedural Hydration to Prevent Acute Kidney Injury After Pulsed Field Ablation for Atrial Fibrillation

Atrial Fibrillation (AF) Acute Kidney Injury

PFA is an emerging non-thermal ablation technology with favorable procedural safety; however, recent studies have raised concerns about peri-procedural hemolysis and subsequent AKI after PFA. This study is a single-center, open-label, randomized controlled trial designed to evaluate whether standardized peri-procedural intravenous hydration can reduce the risk of acute kidney injury (AKI) after pulsed field ablation (PFA) for atrial fibrillation (AF). Eligible adult patients with symptomatic paroxysmal or persistent AF scheduled for PFA will be randomly assigned in a 1:1 ratio to either a standardized hydration strategy or a control strategy without routine prophylactic hydration. The hydration group will receive 0.9% saline at 2 mL/kg/h from entry into the electrophysiology laboratory until 12 hours after the procedure, while the control group will receive no routine preventive hydration and will be treated with fluids only if clinically indicated. The primary outcome is any in-hospital AKI defined according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Secondary endpoints include in-hospital AKI severity by KDIGO stage, in-hospital persistent moderate-to-severe AKI, in-hospital renal replacement therapy, changes in renal function after the procedure, and clinical outcomes through 30 and 90 days, including all-cause death, persistent AKI, renal replacement therapy, all-cause rehospitalization, and composite major adverse events.

Impact of Cocaine Use and Withdrawal on Sleep

Cocaine Use Disorder

This study investigates how cocaine use and withdrawal affect sleep and circadian rhythms in individuals undergoing inpatient detoxification. Using wearable sleep monitors, actigraphy, questionnaires, and hormonal biomarkers, it aims to capture both objective and subjective changes in sleep across three key stages: active use, early withdrawal, and late withdrawal. The study is unique in its ability to explore sleep microstructure, the circadian system's role via melatonin and cortisol measurements, and the dynamic relationship between subjective sleep perception and objective sleep data. It also examines whether sleep quality may serve as a predictive marker of long-term withdrawal success.

Large Language Model for Understanding and Monitoring Elderly Neurocognition

Dementia

Dementia affects millions of people worldwide, and early diagnosis is essential for getting the right care and support. Doctors rely on collateral histories (accounts from family members or caregivers) to understand changes in a person's memory and thinking. However, these histories can be incomplete, unstructured, or difficult to obtain, making diagnosis more challenging. This study will test LUMEN (Large Language Model for Understanding and Monitoring Elderly Neurocognition), an AI-powered conversation tool designed to help caregivers describe their loved one's symptoms more effectively. By asking structured questions and guiding the conversation, LUMEN can create clear, well-organised reports for memory clinic doctors. This could make assessments quicker, more accurate, and less stressful for families. We will test LUMEN in real-world clinics by asking caregivers and doctors to use it and provide feedback. We want to understand how easy it is to use, whether it could improve the quality of information shared, and how it fits into existing NHS memory clinic processes. We will also run co-production workshops with community groups to ensure the tool is accessible to people from diverse cultural and language backgrounds. This research is exciting because it explores how artificial intelligence can improve dementia care. If successful, LUMEN could enhance the diagnostic process, reduce carer burden, and help more people access dementia support sooner. In the future, this tool could be used nationwide in memory clinics, improving care for thousands of families.

A Study of Safety and Drug Levels of ePGT121v1-LS, PGDM1400LS, and VRC07-523LS in Adult Participants Without HIV-1

HIV

This study is testing a lab-made antibody called ePGT121v1-LS that targets a specific part of HIV. Researchers will give it by vein (IV) and under the skin (SC), both on its own and together with two other antibodies, VRC07-523LS and PGDM1400LS, which target different parts of the virus. They will assess safety and side effects, determine the right dose, study how the body processes the drug (pharmacokinetics or PK), and measure how well it neutralizes HIV in the blood (serum neutralizing activity). The expectation is that ePGT121v1-LS, whether given alone or with PGDM1400LS and VRC07-523LS, by IV or SC, will be safe in generally healthy adults and that the antibodies will not interfere with each other when used together. Approximately 83 volunteers in overall good health and without HIV-1 will be enrolled into two parts (A and B). Part A has six groups. In Groups 1-3, participants will get ePGT121v1-LS given by IV at one of three dose levels: 5 mg/kg, 20 mg/kg, or 40 mg/kg. In Groups 4-6, participants will receive three antibodies-first ePGT121v1-LS, then PGDM1400LS and VRC07-523LS-given by IV at two separate visits that are 24 weeks apart. The total study duration for participants in Part A is 48 weeks of scheduled clinic visits. Part B has two groups. In Group 7, people will get ePGT121v1-LS as SC shots at two visits 12 weeks apart. Each visit will give a total of 375 mg, split into three injections of 125 mg each. In Group 8, people will also have two visits 12 weeks apart and will receive three antibodies as SC shots in this order: first ePGT121v1-LS (125 mg), then PGDM1400LS (100 mg), and then VRC07-523LS (100 mg). The total study duration for participants in Part B is 24 weeks of scheduled clinic visits.

Evaluation Of The Success Rate of NOVAMag® SHIELD

Alveolar Buccal Bone Dehiscences Socket Type 3 Subclass B Socket Type 3 Subclass C

This study hypothesizes that the SHIELD technique, when combined with a suitable bone graft material, enables successful immediate implant placement in Type 3 extraction sockets with buccal bone dehiscence, regardless of the extent of buccal bone loss. Specifically, it is proposed that the regenerative potential of the SHIELD technique is not significantly affected by the degree of buccal bone dehiscence, whether in compromised sockets (ST3 Subclass B, when a buccal dehiscence is present and extending 1/3 to 2/3 of the total length of the alveolus) or severely compromised sockets (ST3 Subclass C, for severe dehiscence passing more than 2/3 of the facial bone of the alveolus). All in all, this study aims to assess the clinical performance of the CE-approved medical device NOVAMag® SHIELD by evaluating its success rate and long-term suitability for the rehabilitation of edentulous regions in routine clinical settings. It further seeks to generate clinically meaningful evidence supporting the safety and efficacy of magnesium-based biomaterials in the management of complex post-extraction defects. In addition, the study investigates the CE-approved self-tapping conical implant VEGA® + to obtain comprehensive clinical data contributing to post-market surveillance and continuous product evaluation.

Economic-demographic Assessment of the Aseptic Mobilization of Knee Prostheses Through the RIPO Registry and Radiographic Analysis of the Case Series From the II Clinic of IOR

Aseptic Loosening Arthropathy of Knee

The increase in life expectancy is leading to an increase in the average age of patients undergoing total knee arthroplasty (TKA), and, consequently, an increase in the number of revisions. The main cause of TKA failure is aseptic mobilization, which is described as the loss of integration between the prosthetic component and the bone in the absence of infection. This represents a significant impact on professional and economic resources for the Italian healthcare system. Aseptic mobilization can be caused by inadequate initial fixation of the implant and/or mechanical or biological loss of fixation over time, factors that often occur simultaneously. A careful, methodical evaluation of post-operative radiographs of TKAs remains an important diagnostic tool. The analysis of the causes of aseptic mobilization of TKAs and the associated economic impact in the Emilia Romagna region is useful for providing an estimate of the problem and identifying potential areas for improvement.
