Filter by:This experimental study will look at the effects of INP therapy for two patient groups: 1) patients with reduced peripheral circulation and chronic wounds in patients with renal disease (dialysis patients); 2) and peripheral arterial disease and leg ulcers. The project is designed as a non-randomized clinical trial with single-subject multiple baseline design. Also the intervention will be subjected on the same leg for each individual throughout the study period. The other leg will act as a control. A baseline measure with patient history collection will be performed before a four-week intervention period. These measures include: Segmental pulse-volume-recording, Segmental skin perfusion pressure with a laser Doppler sensor and a pressure cuff to evaluate reactive hyperemia (Sensilase, Väsamed) and a health survey (SF-12/EQ-5D-5L) or similar. After four weeks and eight weeks of intervention, the same tests will be repeated. A final follow-up test will be two weeks after cessation of the intermittent negative pressure intervention. The study will look at the effect of INP on renal failure patients who are given dialysis at a dialysis center located at Oslo University Hospital, Ullevål. Otivio AS has supplied the FlowOx devices and provided the necessary training to perform this project. Outcome variables assessed before, during and after the 10-week study period will be: wound healing, quality of life, skin perfusion pressure and segmental pulse-volume recording. The aim of this project is to prospectively examine and elucidate the effect of intermittent negative pressure therapy on clinically relevant measures related to the reduction of peripheral macro- and microcirculation in patients with renal failure undergoing dialysis treatment. The hypothesis of the study is: - Application of INP in patients with renal failure, by the use of the FlowOx™ device, will improve wound healing and peripheral circulation in the foot compared to before treatment (baseline) in patients undergoing dialysis treatment. - Application of INP in patients with PAD, by the use of the FlowOx™ device, will improve macro- and microcirculation and wound healing in the foot compared to before treatment (baseline) in patients with chronic wounds.
Hemodialysis patients may experience drops in blood oxygen saturation during the hemodialysis treatment, which may lead to hypoxia in the tissues. The investigators hypothesize that: 1. The cumulative number, severity, or other characteristics of such deoxygenation episodes may be a predictor of adverse outcomes in hemodialysis patients. 2. There may be demographic, anthropometric, clinical, treatment prescription, lab analytical, and other parameters that correlate with the number and severity of deoxygenation episodes and, therefore, may be used for risk stratification. Further, some of these parameters may be modifiable.
This is a single center phase I/II open label, exploratory study assessing safety and efficacy of IdeS® (Hansa Medical, Lund, Sweden) given immediately prior to kidney transplantation. We hope that IdeS® will help eliminate DSAs in HS patients who are DSA+ and flow cytometry (FCMX) crossmatch + at time of transplant. We plan to enroll a total of 20 patients. Patients will be followed for 6 months post administration of IdeS®.
Recent reports have suggested that transvaginal NOTES nephrectomy is feasible, yet comparative studies are lacking. The aim of this study was to compare the surgical outcomes of transvaginal NOTES nephrectomy to conventional laparoscopic nephrectomy.
Environmental toxins exert damaging health effects in workers. Thousands of responders who worked or volunteered on the World Trade Center (WTC) rescue and recovery effort following the September 11, 2001 attacks suffer from health conditions or may be at increased risk for worsening health. In a pilot study, investigators identified the first evidence of kidney damage in subjects with very high exposure at Ground Zero. Specifically, noted was a preliminary association between the intensity of particulate matter exposure and albuminuria, a marker of early chronic kidney disease (CKD), systemic endothelial dysfunction, and increased cardiovascular risk. The long-term goal is to minimize the risk of CKD and cardiovascular disease (CVD) among individuals exposed to inhaled toxins. The primary objective of this research is to quantify the risk of kidney damage among first responders to the WTC attack and to determine the relationship to particulate matter exposure as well as determine an association between renal and cardiovascular damage in first responders and to explore potential mechanisms. The central hypothesis is that exposure to inhaled particulate matter causes systemic inflammation and endothelial dysfunction that result in chronic kidney and cardiovascular damage. This hypothesis will be investigated in a subgroup of participants from a previously conducted NIOSH-funded study "Pulmonary Function Abnormalities, Diastolic Dysfunction and WTC Exposure: Implications for Diagnosis and Treatment" ("WTC-CHEST," PI Mary Ann McLaughlin). The proposed study will capitalize on unique resources in WTC-CHEST, including the standardized collection of data on particulate matter exposure and shared risk factors for CKD and cardiovascular disease, and cardiopulmonary function testing. The output from this proposal is anticipated to have a broad impact on understanding the health effects of inhaled particulate matter.
Renal outcome could be different after switching tenofovir to different antiretroviral strategies, in case of renal toxicity. Therefore, it is necessary to evaluate the importance of renal evolution in these patients, in terms of grade and time to renal improvement, according to the different options after interrupting tenofovir. The aim of this study was to explore the renal outcome after tenofovir according to new antiretroviral regimen.
As both patients with end-stage kidney disease and society benefit tremendously from live kidney donation, the safety and well-being of kidney donors are highly important objectives in live kidney donation. Laparoscopic donor nephrectomy has several advantages over open nephrectomy, such as less post-operative pain, better quality of life and shorter hospital stay. Therefore, laparoscopic donor nephrectomy is nowadays the treatment of choice in most countries. So far, modifications of the technique of laparoscopic donor nephrectomy, i.e. hand-assisted and/or retroperitoneoscopic approaches, did not show a significant benefit with regard to safety as reflected by the conversion to open and postoperative complications rate. We therefore believe that further research should focus on the optimization of early postoperative pain and its concomitant use of opioids. Since non-steroidal anti-inflammatory drugs are contra-indicated before and after nephrectomy, the management of postoperative pain largely depends on the administration of opioids. Measures to reduce postoperative pain would also reduce the occurrence of postoperative nausea and vomitus, and postoperative bowel dysfunction. A recent pilot study performed by our group showed that the use of low pressure pneumoperitoneum was feasible and significantly reduced deep intra-abdominal and referred pain score during the first 72 hours after surgery. Previous studies performed by others show that low pressure pneumoperitoneum is associated with reduction of systemic inflammatory response, post-operative pain and analgesic consumption. Martini et al have shown that deep neuromuscular block improves surgical conditions during laparoscopic surgery with standard intra-abdominal pressure. To facilitate the use of low pressure pneumoperitoneum, deep neuromuscular block improves surgical conditions and might become a prerequisite for the use of low pressure pneumoperitoneum. Our hypothesis is that the combination of low pressure pneumoperitoneum and deep neuromuscular block improves quality of recovery in the early post-operative phase.
The goal of this pilot is to reduce the 30-day hospital readmission rate for dialysis patients. It is a quality improvement project that consistent of 4 "tracks." Tracks 1 & 2: Implement use of checklists of activities for staff to complete when patients are admitted to the hospital, and post-hospitalization with emphasis on fluid assessment, nutrition management, patient coaching, and communication between institutions. Track 3: Work with physicians to develop process to individualize post-hospitalization dialysis orders and improve medication reconciliation. Track 4: Use a renal Care Transitions Case Manager to follow patients in the hospital and 30 days post-hospitalization to facilitate care and patient coaching.
The purpose of this study is to assess the safety, tolerability and pharmacokinetics of Ceftaroline in a group of patients with renal disease and matching healthy subjects with normal renal function
Rationale: A deep neuromuscular block is often associated with improved surgical conditions especially in laparoscopic surgery. However, a deep block comes at the expense of a variety of items that may conflict with the use of a deep surgical muscle blockade including a long recovery phase, the need for muscle reversal, postoperative ventilation, impaired postoperative breathing. With the introduction of Sugammadex there is now the possibility to reverse an even deep surgical block. This may overcome most if not all of the issues mentioned. Objective: To assess whether a deep neuromuscular block provides better surgical conditions than a moderately deep block as derived from a surgical rating score. Study design: Single center, double-blind randomized controlled trial. Study population: 24 ASA I-III patients scheduled for laparoscopic renal (n=12, GROUP 1) or prostatic surgery (n=12, GROUP 2). Intervention: In both GROUP 1 and GROUP 2, 6 six patients will receive neuromuscular blockade according to current practice (atracurium (bolus) plus mivacurium (cont. infusion)) aimed at a moderately deep neuromuscular block (1-2 twitches in the Train of Four (TOF) monitor). The other six will receive a bolus plus continuous infusion with rocuronium aimed at a deep neuromuscular block (1-2 twitches post tetanic count (PTC)). All surgical procedures will be performed by one surgeon. Main study parameters/endpoints: To study the surgical conditions in patients undergoing laparoscopic renal or prostate surgery during deep versus less deep neuromuscular block as assessed by the surgical rating score. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Compared to current practice there will be no additional risk.
