The goal of this study is to establish whether use of a digital intervention can improve adherence and alignment with the Kidney Disease: Improving Global Outcomes (KDIGO) Chronic Kidney Disease (CKD) 2024 Guidelines.
A subset of the study will focus on whether the intervention improves outcomes for young adults living with CKD, in the context of the imminent co-location of Children's Health Ireland on the St. James's Hospital campus.
Young adults with CKD transitioning to adult services are recognised as a high-risk and vulnerable cohort, with many individuals unaware of increased cardiovascular risk and mortality¹². In response, and in the context of the co-location of Children's Health Ireland on the St. James's Hospital site, a young adult nephrology clinic has been established.
The KDIGO CKD 2024 Guidelines identify transition as a period of increased risk and include recommendations regarding cardiovascular risk factor targets and the use of therapies known to delay CKD progression³.
Electronic communication is a preferred method for accessing health information among many young adults⁴⁵ and aligns with Sláintecare digital health strategies⁶. A recently established, award-winning St. James's Hospital renal smartphone application is currently used by over 3,000 individuals living with CKD.
The study aims to determine whether use of the application improves adherence to KDIGO guideline recommendations, with the objective of delaying CKD progression and associated complications. The application will support optimisation of care by signposting opportunities for evidence-based interventions (e.g., SGLT2 inhibitors, renin-angiotensin system inhibition) to healthcare providers. The application will also provide participants with tailored recommendations, reminders, educational materials, and collection of patient-reported outcome measures.
Due to the diverse population and range of specialties at St. James's Hospital, the young adult clinic serves distinct subgroups, including individuals with sickle cell anaemia and survivors of cancer and haematological malignancies. These populations will be examined in the context of KDIGO guideline implementation, contributing to a limited international evidence base.
This research evaluates an intervention designed to improve care for adults living with chronic kidney disease.
Eligibility: 16 Years to 30 Years · All · * Adults aged ≥16 years.
* Diagnosed with CKD stages 1-5.
* Owns a smartphone and is capable of using mobile applications.
* Provides informed consent.

A proposed new tool ('DIPLANN-tool' - Digital Planning in Nephrectomy) for predicting kidney perfusion zones on a segmented 3D model during robot-assisted partial nephrectomy (RAPN) for localized renal cancer demonstrated high accuracy when planning selective clamping (SC) for RAPN. However, the tool's clinical added value still needs to be confirmed. Therefore, a randomized controlled trial using a study and control group is the preferred study design.
Experimental group: the use of the DIPLANN-tool + conventional computed tomography (CT) imaging for preoperative planning and perioperative guidance during RAPN.
Control group: the use of only conventional CT imaging for preoperative planning and perioperative guidance during RAPN (= current standard of care).
The primary endpoint is planning and performing as planned a SC strategy. Secondary endpoints include patients' health, patients' insight and surgeons' benefits.
Eligibility: 18 Years to · All · * aged 18 years or above
* cT1-2 N0 M0 renal mass
* planned to undergo RAPN
* multiphase CT scan with arterial phase available
* voluntary given and written informed consent
* sufficient in at least one of the study languages: Dutch, English, French
For the primary objective, SC needs to be deemed possible either according to the DIPLANN-tool in combination with conventional CT imaging or according to conventional CT imaging only, as assessed by an independent surgeon (between inclusion and randomization) who will not be involved in the RAPN surgical procedure, in order to be included in the analysis set. On the DIPLANN tool, SC is deemed feasible if \>= 90% tumor ischemia and \<= 70% renal parenchyma ischemia can be achieved. If these criteria are met, but it is technically or anatomically not feasible according to the independent surgeon to perform SC, he can deviate from these criteria and thus claim SC is not deemed possible. The results for the total population (patients in which SC is deemed possible AND impossible pre-operatively by an independent surgeon) will also be analyzed as a secondary objective.

Various treatment options are available for brain metastases, depending on factors such as lesion site or number lesions. Radiotherapy is a commonly used treatment. Following stereotactic radiotherapy for brain metastases, a potential complication, namely brain radionecrosis, can occur subsequently. It is essential to differentiate between this radionecrosis and lesion recurrence in order to determine the appropriate treatment approach. Contrast-enhanced magnetic resonance imaging (MRI) is the most widely used technique for monitoring brain metastases. Therefore, patients undergo routine MRI at 3 months and during subsequent follow-ups, but if the lesion evolve and if distinguishing between recurrence and radionecrosis is challenging, an \[18F\]-FDG PET scan is then prescribed by oncologists or radiotherapists during follow-up consultations. As part of the standard patient management protocol, a 10-minute image acquisition begins after a 45-60 minutes wait following the radiotracer injection. A second image acquisition is then conducted 3-4 hours later. For both acquisitions, a low-dose X-ray scanner is synchronously coupled to allow attenuation correction of the PET images.
Patient for whom a \[18F\]-FDG PET cerebral examination has been prescribed as part of the usual management of brain metastases will be eligible to the protocol. If the patient agrees to participate, an early imaging session is initiated immediately upon radiotracer injection, lasting 15 minutes in addition to the standard acquisition protocol.
