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.
This study aims to examine the effectiveness of ammonia inhalants in countering the effects of total sleep deprivation on cognitive and physical performance tests relevant to military personnel.
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).
A total of 18 military pilots in their tirocinium in the air force academy from the Portuguese Air Force course "Masters in Military Aeronautics: aviator pilot specialist" participated in this study. Participants were randomly assigned to yoga (intervention group) or waiting list (control group). Procedures were approved by the Évora University research ethics committee and participants will give written informed consent according to the Helsinki declaration (approval number: 21050).
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.
Healthcare teams often encounter challenging circumstances where they must deliver high-quality care. For a team to function effectively, its members must not only be individually competent, but they also need to collaborate and cooperate using their respective expertise. Such teams often work under high stress situations, where they need to make high stakes decisions under conditions of uncertainty, time-sensitivity and variable levels of control. Research shows that such emergency situations provoke stress responses in individuals, which can impair attention, memory, reasoning, and decision-making. However, it remains unclear how individual-level stress responses influence team communication, coordination, and performance. The aims of this study are to a) compare team coordination, communication, and performance in low stress versus high stress simulated emergency situations; and b) characterize the relationship between teams' stress profiles and the teams' performance and coordination. The study will be a within-subject experimental design, with teams serving as their own controls. Teams of emergency medicine residents and nurses will participate in two simulation scenarios: one in a low stress condition, and the other in a high stress condition (counterbalanced across the teams).
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.
Biomechanical literature suggests that runners who utilize a mid or forefoot strike pattern may suffer from a reduced incidence of chronic injuries compared to a rearfoot strike. This investigation examined the effects of a 10-week footstrike transition intervention on tibial stress fracture risk in runners.
