Filter by:The intravenous injection of lidocaine during the perioperative period has been widely used in various types of surgeries. Its clinical effect includes reducing stress response during anesthesia, decreasing pain and opioid consumption, lowering the incidence of postoperative nausea, vomiting, cognitive dysfunction, and reducing the injection pain of propofol. However, despite the positive impact of lidocaine on surgical patients, its mechanism of action remains unclear. Serum N/OFQ is a neurotransmitter that plays an important role in regulating pain and emotion. Therefore, this study aims to explore the effects of perioperative intravenous injection of lidocaine on stress responses in surgical patients, as well as its mechanism of action, and whether Serum N/OFQ participates in this process.
The primary purpose of this study is to determine whether or not there is a correlation between MRI and ultrasound for the diagnosis of lower limb stress injuries. Patients that are seen at the University of Iowa Sports Medicine Center with a suspected diagnosis of a lower limb stress injury will be recruited. These patients will undergo a diagnostic ultrasound of the affected region prior to undergoing an MRI of that region. Then, the ultrasound findings will be compared to the MRI findings to determine if a correlation exists.
The goal of this clinical trial is to compare photobiomodulation therapy (PBMT) in addition to standard of care in the treatment of tibial and metatarsal bone stress injuries in a military training setting. Participants will all receive usual care and also be randomized to either active or sham photobiomodulation therapy. Effectiveness will be assessed based on time to return to duty and measures of pain and function. - Participants will receive care for a maximum of 6 weeks. - Participants will have follow-up through 4 months (or graduation/dismissal from training, whichever comes first).
The goal of this study is to learn about whether ethnic minority adolescents' racial discrimination experience is related to dysregulated biological responses to subtle racism, and how the relationship may be attenuated or exacerbated by a set of social and cognitive factors. The main questions it aims to answer are: - to reveal the relationship between racial discrimination experiences and ethnic minority adolescents' stress response to subtle racism - to test parental ethnic-racial socialization, children's attribution to subtle racism and their racial identity as potential risk and protective factors.
Meniscus injuries are a very common cause of knee pain. The meniscus is a semilunar fibrocartilage structure found on the medial and lateral sides of the knee. The meniscus serves to absorb impact and protect the articular cartilage during weight-bearing activities, joint stability, proprioception, and nutrition. This has a significant effect on knee biomechanics. After the menisci are injured, the biomechanics of the knee change so that degenerative changes occur more frequently in the tibiofemoral compartment. Improvement of tibiofemoral arthrosis after meniscectomy surgery has been demonstrated in several long-term clinical studies. With increasing awareness of the importance of the meniscus in knee biomechanics, various meniscus repair techniques have been developed. In addition, several adjuvants for healing have been proposed to enhance meniscus healing. However, a study showed the meniscal repair failure rate increased from 22% to 24% at 5 years. Study found the healing rate of meniscus repair, which was accompanied by ACL repair, had a greater healing rate, 93% vs. 50%. Hemarthrosis that occurs after bony tunneling during ACL reconstruction provides a fibrin clot and an environment rich in factors that promote healing of the newly repaired meniscus. The fibrin clot provides the structural foundation for meniscus healing. Transmission factors, such as fibronectin and growth factors, are also present. Microfracture is a common procedure used for the treatment of damage to the articular cartilage in the knee. This procedure is used to stimulate the production of fibrocartilage in areas of injured cartilage. Microfractures are performed by creating 1 or more small channels (1 to 3 mm in size) that pierce the subchondral bone and release bone-forming components into the joint. Microfractures serve to promote the formation of fibrocartilage over damaged cartilage. Research in 2016 used an animal model (Capra hircus) to investigate the effectiveness of the microfracture technique on meniscus tear healing rates. They found significant healing in meniscal repair accompanied by microfracture technique (65% vs 12%). However there is still not enough research regarding the efficacy of microfracture in meniscal healing, especially among Indonesian. Therefore, the investigators aim to investigate its efficacy.
This study is a prospective randomized controlled study of Combined microfracture procedure promotes tendon healing during double raw repair for full tear rotator cuff. The patients with rotator cuff tear were randomly divided into groups before the operation. The patients were followed up before and 6 weeks, 3 months, 6 months, 12 months after surgery. In different time periods, the quantitative and qualitative indicators including pain, functional score, muscle strength, MRI performance, etc. were compared between groups at the same time period to evaluate the difference in the effect of Crimson duvet procedure with Greenhouse procedure on the treatment of rotator cuff.
The current study seeks to build on previous research that demonstrates the efficacy of Acceptance and Commitment Therapy in combating stigma by investigating the feasibility and acceptability of a protocol to support Black adolescents and young adults in coping with race related stress. The study will consist of a small, purposeful, non-randomized sample (N = 30) of clients enrolled into a 10-session Acceptance and Commitment Therapy group. The group will be offered as part of regular clinical care at the Division of Adolescent and Young Adult Medicine. Three consecutive groups will be run with approximately 8-10 participants in each group over the next year.
The goal of this clinical trial is to test whether there is any effect on rotator cuff healing by making microfracture at the lateral side of the footprint. The main question it aims to answer are: - [whether the lateralized microfracture could decrease the retear rate after arthroscopy rotator cuff repair.] - [whether the lateralized microfracture could improve the functional recovery after arthroscopy rotator cuff repair.] Participants with medium to larger size rotator cuff tears will be randomly assigned to the study group treated with lateralized microfracture immediately after arthroscopy rotator cuff repair or the control group treated with conventional arthroscopy rotator cuff repair without microfracture.
Research has shown that activation of the sympathetic nervous system for extended periods or during certain times in life can increase the risk for Alzheimer's disease. Some research in animal models show that acute activation of the sympathetic nervous system through stress exposure can increase certain Alzheimer's disease-related biomarkers, such as amyloid-beta, within hours of exposure. However, how acute sympathetic nervous system activation via stress exposure affects amyloid-beta levels in humans has yet to be examined. In this study, the investigators will examine whether brief increases in sympathetic activation result in immediate changes in plasma amyloid-beta levels in the five hours after exposure.
The purpose of this study is to examine racial differences in smoking behaviors and stress responses between African American and white male smokers.
