Filter by:The overarching hypothesis is that CF carriers are at increased risk for developing most of the extrapulmonary conditions associated with CF compared to the general population. Specifically, it is hypothesized that this pilot data will detect subclinical evidence of pancreatic and kidney disorders among CF carriers. This will be determined by bringing CF carriers and controls to the CRU for one visit where they will answer survey questions and undergo laboratory testing. Additionally, they will collect urine and stool samples at home that will be sent to outside laboratories for testing.
The primary aim of this study is to extend follow up of TESTING study participants and to assess the long-term effects of a 6-9-month course of oral methylprednisolone on End Stage Kidney Disease (ESKD), according to dose (full-dose vs reduced-dose), ethnicity (Chinese vs other) and kidney function (eGFR above and below 60 mL/min/1.73m2).
To estimate the characteristics, pathogenesis, risk factors and intervention measures for different stages of heart and kidney diseases, and to optimize the curative effects of different treatment schemes
This study in being conducted in men who have low testosterone and chronic kidney disease. The investigators will evaluate the effects of an oral testosterone preparation, JATENZO, on testosterone levels and hemoglobin (red blood cells).
Objectives and aim: To evaluate the long-term spill-over (indirect) effect of Coronavirus disease (COVID-19) on health outcomes and healthcare utilization among people with non-communicable diseases and without COVID-19. Design: A population-based cohort study using electronic health records of the Hospital Authority (HA) clinical management system, economic modeling, and serial cross-sectional surveys on healthcare service utilization. Setting: HA public hospitals and outpatient clinics in Hong Kong Participants: People aged ≥ 18 years with a documented diagnosis of diabetes mellitus, hypertension, cardiovascular disease, cancer, chronic respiratory disease, and chronic kidney disease; without COVID-19; attending HA services between 2010 and 2024. Main outcome measures: All-cause mortality, disease-specific outcomes, healthcare service utilization, and costs. Methods: The annual incidence of each outcome in each year between 2010 and 2024 will be calculated. An interrupted time-series analysis to assess the changes in outcomes between pre-and-post-COVID-19 outbreak periods. Long term health economic impact of healthcare disruptions during the COVID-19 outbreak will be modeled using microsimulation. Multivariable Cox proportional hazards regression and Poisson/negative binomial regression to evaluate the effect of different modes of care on the risk of the outcomes. Implications: Findings will inform policies and practices on contingency care plans to avoid excessive morbidity and mortality and to assure the quality of care for patients with NCD as part of the territorial response to the health crisis.
BACKGROUND: Preeclampsia (PE) is a serious syndrome that affects 3-7% of all pregnant women. PE is characterized by hypertension and kidney problems after the 20th week of pregnancy and is associated with an increased risk of serious cardiovascular complications including death in both mother and fetus. The underlying disease mechanisms are not clear, but that there are changes in the vessels and their function is generally accepted. Today, there is a lack of medical treatment in the form of medicines. HYPOTHESIS: So-called oxidative stress and deficiency of the vasodilator nitric oxide (NO) play an important role in disease onset and complications in PE. WORK PLAN: This interdisciplinary project combines clinical and experimental studies to investigate the significance of oxidative stress and NO deficiency in PE. We have shown in previous studies that nitrate, which is found in high levels in lettuce and beets, can be converted to NO in the body. In a feasibility study, blood samples were taken from women with PE and healthy pregnant women. Analysis of these samples has shown that women with PE and their newborns have lower levels of nitrate and markers of NO in the blood. In a clinical study, the physiological effects (cardiovascular function, renal function, metabolic function) of an increased daily nitrate intake (in the form of a specially developed beetroot juice) are examined in patients with PE. Blood and urine samples are collected before and after beetroot intervention and during childbirth when umbilical cord and placenta samples are also collected. The samples are analyzed with biochemical analyzes with regard to e.g. oxidative stress and NO. IMPORTANCE: The project is expected to contribute new and important knowledge regarding the disease mechanisms, which may enable new treatment strategies in PE.
This is an retrospective and prospective multicenter study to develop and validate an artificial intelligent (AI) aided diagnosis, therapeutic effect assessment model including chronic kidney disease (CKD) and dialysis patients starting from April 2009, which is based on ophthalmic examinations (e.g. retinal fundus photography, slit-lamp images, OCTA, etc.) and CKD diagnostic and therapeutic data (routine clinical evaluations and laboratory data), to provide a reliable basis and guideline for clinical diagnosis and treatment.
This is a multicenter prospective, longitudinal cohort study which will evaluate the predictive capacity of machine learning (ML) models for progression of CKD in eligible patients for a minimum of 12 months and potentially for up to 4 years.
This study is open to adults with a type of kidney disease called focal segmental glomerulosclerosis (FSGS). The purpose of this study is to find out whether a medicine called BI 764198 improves the health of the kidneys in people with FSGS. Three different doses of BI 764198 are tested in this study. Participants are put into 4 groups randomly, which means by chance. Three of the groups receive different doses of BI 764198 and one group receives placebo. Participants are in the study for about 4 months. For about 3 months, they take BI 764198 or placebo as capsules once a day. Placebo capsules look like BI 764198 capsules but do not contain any medicine. Participants visit the study site about 10 times. You can participate in this study from your home. In this case a research nurse will visit you for the study visits. Kidney health is assessed based on the analysis of urine samples, which participants collect at home. At the end of the study, the results are compared between the different groups. During the study, the doctors also regularly check the general health of the participants.
Stone disease is a common condition, affecting approximately 9% of Americans in 2007. It causes great morbidity and is also a costly condition, estimated to cost the US healthcare system approximately 3.79 billion dollars in 2007. Ureteroscopy (URS) is the most commonly performed surgical treatment for upper tract stone disease. Ureteral stenting is a common practice after ureteroscopy and placed in ~75% of cases to prevent ureteral edema and renal obstruction. Unfortunately, ureteral stenting can be very painful and has been shown to increase the rate of emergency room visits. Many strategies have been attempted to decrease pain with ureteral stenting including modification of stent material and designs, but efforts so far have been unsuccessful in decreasing stent-related morbidity. Stent-related morbidity is hypothesized to be secondary to irritation of ureteral/bladder mucosa and muscle. Analgesics such as alpha blockers and NSAIDs have been shown to reduce stent morbidity. Anticholinergic drugs are also utilized as they decrease bladder spasms and, therefore, are hypothesized to reduce stent irritation. However, the evidence for anticholinergics has been conflicting. Anticholinergics also have a serious side effect profile including dry mouth, dry eyes, constipation, urinary retention, blurred vision, and even dementia. Some authors even hypothesize that these side effects may offset any purported benefits the anticholinergics provide for stent-morbidity. Methocarbamol is anti-spasmodic muscle relaxant that is believed to work by acting on central neurons and possibly by blocking sodium channels. Given that anticholinergics have many side effects and questionable efficacy, the investigators hypothesize that methocarbamol may achieve superior analgesia for stent morbidity and stent-related bladder spasms. Oxybutynin is used for the treatment of overactive bladder. The rationale is that the oxybutynin relaxes the muscles in the bladder to help decrease problems of urgency and frequent urination caused by the urinary stent irritation. Since anticholinergics have multiple side effects, finding an equally efficacious alternative with less side effects is highly desirable. This study will evaluate the clinical and demographic factors of patients undergoing ureteroscopy and treated postoperatively with methocarbamol vs. oxybutynin for stent-related morbidity. Additionally, the study will aim to understand the postoperative outcomes and complication rates of patients discharged with methocarbamol vs. oxybutynin after ureteroscopy with a ureteral stent in place.
