Filter by:Fluorescence is one of the most commonly used research and detection techniques in the field of biomedical science. The characteristics of fluorescent probe directly affect the performance and application of fluorescence analysis and imaging. Aggregation-Caused Quenching has limited the application of traditional fluorescent probes to some extent. This project intends to systematically evaluate the detection efficiency of new methods through the detection of biomarkers in clinical samples and the comparison with the detection methods of traditional biomarkers, so as to provide theoretical and experimental basis for the establishment of fast and simple biomarker detection technologies with new biological probes.
Elderly people (EP) have increased, as well as life expectancy at birth. In Chile there are more than 2 million 800 thousand EP, which corresponds to 1/6 of the Chilean population. The EP have a higher disease burden and mortality when facing surgery and in the postoperative period. Thus, this population frequently has longer hospital stays due to its degree of fragility, surgical complications or decompensation of its underlying pathologies, directly affecting health care systems. An inadequate preparation of the EP prior to surgery determined that the requirements of in-hospital as well as out-of-hospital care are extended, with the consequent which entails a higher cost in health. Current research underestimates the conditions of frailty and dependence in the EP. In addition, it is not routinely evaluated prior to surgery, as well as nutritional, metabolic, cognitive status and / or delirium screening is performed. There are accelerated recovery programs, which relate their interventions to specific pathologies; however, the age of the person is not taken into account. Surgical pre-habilitation interventions in the EP usually focus their efforts on physical and cardiovascular aspects, not including an integrative pre-surgical evaluation. Based on the foregoing, a prospective, interventional, longitudinal and randomized study has been proposed in a population of the EP who will undergo elective urology and coloproctology surgeries in two university hospitals (private and public). The objective of this study is to evaluate how the implementation of a timely pre-surgical conditioning (APO) protocol for frail elderly people reduces the days of hospital stay. The APO considers the most relevant aspects of physical and cardiovascular pre-habilitation, in addition to contemplating evaluations of frailty, dependence, cognitive status, screening for delirium, nutritional and metabolic.
To investigate the effectiveness of percutaneous nephrostomy catheter placement versus retrograde double J catheter placement in patients with symptoms of obstructive kidney disease (with either infection and/or pain and/or kidney function deterioration) caused by urolithiasis.
The role of bowel bladder disorder, or BBD, has been highlighted as a major player in vesicoureteral reflux and urinary tract infection (UTI). However, the diagnosis of BBD are still conceptual and subjective, because of the diagnosis of constipation, main pathophysiology in BBD has not been established well.
A study looking at the feasibility of doing a full-scale RCT that investigates the use of tranexamic acid intravesically prior to continuous bladder irrigation treatment in the emergency department for urinary retention due to clots. We want to know: - patient experience and acceptability of the intervention - study procedures (recruitment, site appropriateness, staff engagement) - safety data - identify resource use
Over 30 million surgeries are performed annually in the US. Up to 30% of surgical patients experience delayed surgical recovery, marked by prolonged post-surgical pain, opioid consumption, and functional impairment, which contributes $8 billion annually to US health care costs. Novel interventions that improve the resolution of pain, minimize opioid exposure, and accelerate functional recovery after surgery are urgently needed. Multi-modal pre-operative optimization programs (or "prehab") integrating exercise, nutrition, and stress reduction have been shown to safely and effectively improve outcomes after surgery. However, no objective biological markers assess prehab effectiveness and are able to tailor prehab programs to individual patients. Surgery is a profound immunological perturbation, during which a complex network of innate and adaptive immune cells is mobilized to organize the recovery process of wound healing, tissue repair, and pain resolution. As such, the in-depth assessment of a patient's immune system before surgery is a promising approach to tailor prehab programs to modifiable biological markers associated with surgical recovery. The primary goal of this clinical trial is to determine the effect of a personalized prehab program on patients immunological status before surgery.
Anesthesia in urological surgeries might constitute a great challenge to anesthesiologists. Especially that a great proportion of these patients are elderly with a lot of comorbidities. This put these patients at the risk of developing medical adverse events after being anesthetized by general anesthesia. The aim of this study is to compare between intravenous sedation with analgesia versus general anesthesia in patients undergoing urological surgical procedures.
Previous experimental studies concluded that angiotensin receptor blockers can ameliorate the harmful inflammatory and histological changes after relief of obstruction. Nevertheless, these witnessed effects have not been yet translated into the clinical practice.
Antimicrobial resistance is one of today''s most urgent public health problems. An important strategy to slow the spread of antimicrobial resistance is the promotion of judicious antimicrobial use. There are many opportunities to reduce unnecessary antimicrobial-prescribing, including in patients undergoing surgical procedures. The following study will specifically study opportunities to improve antimicrobial use in patients undergoing common urologic procedures at hospitals in the Veterans Health Administration (VHA). Guidelines recommend giving antibiotics for no more than 24-hours after most urologic procedures, but the investigators have shown that the unnecessary use of post-procedural antimicrobials is common in this setting. In a national cohort of nearly 30,000 VHA patients, excessive post-procedural antimicrobials were prescribed after 37.2% of urologic procedures for a median duration of 3.0 excess days. In this study, the investigators will evaluate whether giving regular feedback to providers at 3 VHA hospitals can reduce unnecessary antimicrobial use after urologic procedures.
Urinary tract obstruction is a serious health problem due to kidney damage. Relative renal function has an important role in the treatment of obstructed kidneys. Nephrectomy can be recommended when the relative renal function is 10% or less in radionuclide examinations. Recently, however, nephron sparing approaches have come to the fore. This indicated the need to evaluate the possibility of recovering the function of the kidney before nephrectomy. The aim of this study is to compare relative functions of obstructed kidneys in technetium 99m dimercaptosuccinic acid scintigraphy (DMSA) before and 2 weeks after nephrostomy tube.
