Food Frequency Questionnaire to Assess Sodium Intake

EvalSel can precisely assess the salt intake of hospitalized patients in nephrology and cardiology or in medical consultation. It can determine salt consumption to the nearest gram. The objectives of this food frequency questionnaire are to arrive at a precise dietary diagnosis and to quickly identify the dietary errors made by the patients. EvalSel is useful for doctors to quickly obtain an assessment of the salt consumption of their patients, so they can refer them to dietitians if necessary. It can be used on the day of admission to hospital or during medical follow-ups to know the evolution of their consumption over the long term and improve their care.

Comparison of HYDROLINK™ and HeprAN™ mEmbranes in a Per Dialytic Heparin Weaning Strategy in Chronic Hemodialysis Patients

Chronic kidney disease (CKD) results from the progressive and irreversible destruction of the kidneys. As of December 31, 2018, there were 89,692 people in France undergoing replacement therapy, including 49,271 (55%) on dialysis and 40,421 (45%) with a functioning kidney transplant. The primary treatment modality is currently hemodialysis. It is known to activate the coagulation cascade and blood platelets, leading to thrombus formation and premature termination of the hemodialysis session. This loss of circuitry results in a decrease in session time leading to an insufficient dialysis dose and blood loss in patients who are already often anemic due to their chronic renal failure. To avoid this complication, current recommendations recommend the use of unfractionated heparin (UFH) or low molecular weight heparin (LMWH) during the hemodialysis session at the cost of an obligatory hemorrhagic risk due to the systemic administration of heparin. However, this risk of bleeding is already very high, due to platelet dysfunction, a direct consequence of uremic toxin impregnation in these patients. In addition, this hemodialysis population is frequently exposed to antiplatelet agents and anticoagulants (heparin or VKA), which aggravate the hemorrhagic risk inherent to renal pathology. In this context, bioactive membranes such as the HeprAN™ membrane, coated in heparin, have been developed to minimize or even eliminate the need for anticoagulation during sessions in chronic hemodialysis patients. Several studies with this membrane have demonstrated the absence of the need for additional heparin in populations with no particular bleeding risk and in populations at risk of bleeding: post-operative (HepZero study), patients on VKA. The HYDROLINK™ membrane offers the same anticoagulant prospects as the HeprAN™ membrane, but its mode of action involves the use of a copolymer with hydrophilic properties, making it possible to avoid the presence of heparin. This membrane would have an influence on platelet aggregation. It would also make it possible to avoid the risk of heparin-induced thrombocytopenia (HIT) by completely excluding heparin from the dialysis session

Extended-Release Tacrolimus Following Liver Transplantation

Medications used after transplant to prevent rejection are associated with many side effects. Tacrolimus side effects include kidney dysfunction; tremor, headaches, difficulty sleeping, change in sensation (legs), seizure, or confusion; high blood pressure; anemia, or low blood cell counts; diabetes; abnormal cholesterol and weight gain. The investigators want to use a new, approved, formulation of the standard medication (Envarsus) as they believe it may be associated with reduced side effects. The investigators would like to assess how safe it is to use this medication and how well it works in comparison to currently used formulations. The investigators will study if there are less side effects and will study clinical outcomes (including how well the liver does and if there is need for hospitalizations after transplant). The investigators hope that this information will improve the care provided to and outcomes in patients following liver transplant.

Chronical Illness-related Limitations of the Ability to Cope With Rising Temperatures, Third Wave

The CLIMATE-III Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific health behavior, somatosensory amplification, risk and benefit perception, self-efficacy, health literacy, and the degree of urbanisation of the patients' administration district are associated with these effects. Study participants from Germany and Italy will be included in the sample.

A Pharmacokinetics and Safety Study of Azvudine Tablets in Subjects With Mild-To-Moderate GFR Decline in Renal Insufficiency and in Healthy Subjects

Azvudine(FNC)，a nucleoside reverse transcriptase inhibitor, make itself a better candidate to be co-formulated in other anti-HIV therapies, thus to improve patient's compliance. FNC is a broad-spectrum RNA virus inhibitor that inhibits the novel coronavirus RNA-dependent RNA polymerase. This trial uses a non-randomized, open-label, parallel, single-dose adaptive design aimed at investigating the effects of varying degrees of renal insufficiency on the pharmacokinetics, safety, and tolerability of a single oral dose of 3 mg Azvudine tablets in humans. On the first day of the study, a single oral dose of 3 mg ( 3 tablets ) of Azvudine tablets is taken orally on an empty stomach. Biological sample collection and safety examination will be performed in this trial.

Amino Acid Loss During Continuous Renal Replacement Therapy

The goal of this observational study is to learn about amino acid loss during continuous renal replacement therapy and plasma amino acid levels in intensive care patients. The main questions it aims to answer are: What amount of amino acids is lost over the duration of continuous renal replacement therapy? How do amino acid plasma concentrations change over time in patients with and without continuous renal replacement therapy? Amino acid concentrations will be measured in the effluent and in the plasma of patients receiving continuous renal replacement therapy as part of their regular medical care. In addition, plasma concentrations of amino acids will be studied in patients without renal replacement therapy.

Registry of Pre-mixed Solutions in Critically Ill Patients on the Continuous Renal Replacement Therapy

This is a multicenter, prospective, registry study. By collecting relevant demographic information and clinical data of patients receiving continuous renal replacement therapy (CRRT) with pre-mixed solutions, the clinical applicability of pre-mixed solutions will be evaluated in critically ill patients in real-world clinical settings. This study will be carried out in approximately 10 study sites in China. Patient data will be collected to evaluate the clinical applicability of pre-mixed solutions.

Study of the Quality of Life in School Aged-children With Posterior Urethral Valves

Posterior urethral valves (PUV) are the most common congenital obstructive lesion of the urethra, affecting from 1 per 3000 to 1 per 8000 live births. Valve ablation usually resolves the obstruction in PUV but patients still may suffer of deterioration in renal and urinary functions. Renal insufficiency is the most feared long-term complication. Up to 50 % of the patients will develop chronic kidney disease (CKD), and up to 20 % will develop end-stage renal disease (ESRD) and ultimately will require kidney transplantation. PUV is the first urological cause of ESRD. Progression towards CKD depends on febrile urinary tract infections (UTIs), severity of a vesicoureteral reflux and bladder dysfunction. Bladder dysfunction is due to an overactive and small poorly compliant bladder during infancy. Detrusor overactivity usually decreases in childhood and bladder capacity increases. The most common symptom of this bladder dysfunction is urinary incontinence. 60 % of children are continent at the age of 5 years old and 90 % at 10 years old. In case of persistent bladder dysfunction, medical treatment (anticholinergics, alpha-blockers) may be introduced, or even intermittent catheterizations. Current scientific literature has very few studies on quality of life (QoL) in patients with PUV, mostly in adult patients and very small cohorts. Men treated for PUV in childhood had a good quality of life compared to the normative population, except for sleeping, eating and sexual activity. It seemed that the more severe the urological and nephrological functions were, the lower the QoL was. Children were only asked about intermittent urinary catheterization, and family point of view has never been collected. However, QoL and long-term evolution represent the first concerns of parents-to-be in prenatal counseling, or after diagnosis in an infant with PUV. Hence, the aim of the study is to investigate the quality of life in school-aged children who had been treated for PUV in their first year of life, as measured by the Pediatric Quality of Life Inventory Version 4.0 (PedsQL 4.0).

SelfWrap-Assisted Arteriovenous Fistulas

This is a single-center, prospective, single-arm clinical study to evaluate the feasibility, safety, and performance of VenoStent's SelfWrap® Bioabsorbable Perivascular Wrap on arteriovenous fistulas (AVFs). All participants are chronic kidney disease (CKD) patients already receiving hemodialysis treatments that are referred for creation of a new arteriovenous fistula (AVF).

To Evaluate the Efficacy and Safety of Tenofovir Alafenamide Conversion in Liver Transplant Patients

This clinical trial aims to confirm the efficacy and safety of Vemlia® tablets (Tenofovir alafenamide) in liver transplant patients with hepatitis B, focusing on their effects on renal function. HBV reactivation post-liver transplantation can result in a post-transplant mortality rate of up to 50% within two years, making prophylaxis critical. Currently, a combination therapy of HBIG and nucleotide analogues is commonly used. Among the nucleotide analogues (NA), entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are frequently used as first-line therapies. However, both ETV and TDF have nephrotoxicity, requiring caution in patients with chronic kidney disease. Specifically, 18% of liver transplant patients develop chronic kidney disease due to immunosuppressant use, making the appropriate use of antiviral drugs to preserve renal function crucial. TAF has been reported through RCTs to be more effective than TDF in preserving renal function and bone density, while showing similar antiviral effects. However, these studies have been conducted exclusively on general chronic liver disease patients. Although multicenter studies have been reported for liver transplant patients, they were retrospective and involved a limited number of patients. Therefore, the primary objective of this study is to assess the impact of converting to TAF on renal function preservation in liver transplant patients taking antivirals for HBV prophylaxis. The secondary objectives are to evaluate the antiviral effect on HBV, the impact on lipid profiles, and the effectiveness in preserving bone density.

Tolerability and Safety of CARDIOMEMS™ Intracardiac Continuous Cardiac Hemodynamic Monitoring Device in Patients with Cardio Renal Syndrome with Severe Renal Impairment

Renal failure is present in 40% of heart failure patients, and is one of the main comorbidities of heart failure. Follow-up with pulmonary artery pressure (PAP) monitoring has shown a reduction in mortality and frequency of hospitalization in patients with heart failure alone in the CHAMPION trial. Patients with New York Heart Association class III heart failure and a hospitalization in the previous 12 months were included in that study. They benefited from the "CardioMEMS™ HF" device with a sensor implanted in the pulmonary artery to measure PAP. According to that study, the information led to more precise and early adaptation of therapy by avoiding the onset of heart failure symptoms and reducing the number of hospitalizations. However, in that study, patients with impaired renal function (Glomerular Filtration Rate\<25 mL/min/1.73m2) were excluded, limiting the indication for treatment in those patients, and the evolution of renal function during the study was not reported. Patients with heart failure AND advanced renal failure are defined as having a cardio-renal syndrome, with strong interaction between these 2 organs. In the event of predominant right heart failure, they may require treatment by renal replacement or dialysis. There seems to be a link between high venous pressure, renal repercussions and the need for dialysis. Additional follow-up data in this clinical situation are needed to confirm this link and to suggest the interest of continuous PAP monitoring to improve the management of these patients with cardio-renal syndrome with severe renal impairment defined by a Glomerular Filtration Rate\< 30 ml/min/1.73m2 (KDIGO Cardio-renal 2019). This pilot study aims to evaluate how tolerable the "CARDIOMEMS™ HF" device in patients with cardio-renal syndrome and obtain the first information on the relationship between cardiac hemodynamics and renal function in this population.

EuroSIDA - Clinical and Virological Outcome of European Patients Infected With HIV

The EuroSIDA study is a prospective observational cohort study of 23,000+ patients followed in 100+ clinics in 35 European countries, Israel and Argentina. The study is the largest pan-European cohort study and few studies of a comparable design are available on a global scale. The EuroSIDA study is an ongoing collaboration and patients have been enrolled into the study through 11 cohorts since 1994. The main objective of the study remains the same as in 1994: to prospectively study, clinical, therapeutic, demographic, virological and laboratory data from HIV-1 positive persons across Europe in order to determine their long-term virological, immunological and clinical outcomes. Historically, EuroSIDA has been crucial in reporting key changes in the HIV epidemic, such as the dramatic changes in morbidity and mortality when combination anti-retroviral therapy (cART) was first introduced. As new anti-HCV treatment is introduced to HIV/HCV co-infected patients, it is important for EuroSIDA to remain in the forefront of investigating the treatment benefits and adverse effects. All study documents, study status, newsletters, scientific publications and presentations are available online and are updated continuously at project website. In general terms, the objective of the EuroSIDA study is to continue a long-term, prospective collection of clinical, laboratory and therapeutic data as well as plasma on a large cohort of consecutive HIV infected patients from across Europe in order to (1) assess the factors associated with the clinical, immunological and virological course of HIV infection and HIV-related co-infections and co-morbidities, and (2) continue to provide and develop a surveillance system to describe temporal changes and regional differences in the clinical course of HIV and HIV-related co-infections and co-morbidities in Europe.

DV Combined With Toripalimab for Renal Preservation in Solitary Kidney or Renal Insufficiency or Bilateral Multiple UTUC

Approximately 20 participants will be enrolled in the study to evaluate the efficacy and safety of the combination of DV (DV, 2.0 mg/kg, intravenously administered every 2 weeks) and toripalimab (toripalimab, 3.0mg/kg, intravenously administered every 2 weeks). Subjects will receive 6 cycles of DV and toripalimab, followed by laser surgery to remove ureteral or renal pelvis tumors, followed by 12 cycles of DV and 1 year of toripalimab consolidation therapy. Efficacy and safety were evaluated by cystoscopy, ureteroscopy, laboratory tests, and imaging examinations after treatment.
