Filter by:Perioperative neurocognitive impairment, including postoperative delirium (POD), is common in older patients after anesthesia and surgery and is associated with poorer short- and long-term outcomes, including worsening cognitive decline, surgical Complications, increased risk of hospitalization, and death after cardiac and noncardiac surgery. POD is more common with age, occurs in up to 65% of elderly patients, and increases in patients with mild cognitive impairment. As more and more older adults undergo surgery and anesthesia, POD has become a major global health challenge requiring urgent attention. Prevention strategies involving multidisciplinary perioperative interventions may have some benefit overall, but the impact on POD remains uncertain. Known inflammatory responses may be associated with adverse outcomes such as neurocognitive dysfunction and cancer recurrence after major surgery. Different anesthesia methods, the regulation of anesthesia drugs on postoperative inflammatory response has been confirmed in vitro, but its clinical significance is still unclear. Therefore, exploring the risk factors of inducing POD has important clinical significance for the early prevention of POD. Second, a recent study found that the incidence of POD was significantly higher in patients whose sleep cycle was disturbed during hospitalization. Animal experiments found that after 5 hours of sleep deprivation in adult mice, the number of dendritic spines in CA1 neurons in the hippocampus was reduced, and the length of dendrites was significantly shortened, which damaged the synaptic transmission of the central nervous system, and significantly improved memory and cognitive function. Damaged. And many studies have investigated whether bispectral index (BIS)-guided anesthesia is associated with a reduced risk of POD, compared with "standard-of-care" anesthesia or the use of goal-directed end-tidal volatile agent concentrations, the reasoning is that the use of BIS-guided anesthesia results in less anesthesia exposure, and therefore "light" anesthesia may reduce the incidence of postoperative POD compared to "deep" anesthesia. However, this conclusion is still controversial. The study of Anshentong et al. has confirmed that deep anesthesia with BIS maintained at 40-49 can delay postoperative recovery time, reduce the level of inflammatory factors and the incidence of early postoperative cognitive impairment, and reduce the incidence of early postoperative cognitive impairment. Brain damage. Therefore, although age is known to be the main correlative factor for POD, different depths of anesthesia may cause different stress responses in patients, resulting in different release of inflammatory factors. An additional risk factor may be preoperative psychiatric symptoms, and assessment of mental status is often overshadowed by concerns about multiple comorbidities in older adults. Anxiety disorders are one of the prominent psychiatric symptoms in older adults. very common. Preoperative anxiety is defined as an unpleasant restless or tense state secondary to patient concerns about illness, hospitalization, anesthesia, surgery, or the unknown. Studies on the relationship between preoperative anxiety and POD also vary in consistency due to the characteristics of different populations. Many of the current studies are mostly single-center with limited sample size, which may have a certain bias in the conclusions. Therefore, the investigators designed and planned to conduct a multi-center, large-sample cohort study to determine the impact of perioperative related factors and inflammatory markers on elderly patients undergoing non-cardiac major surgery .
Immune checkpoint inhibitors (ICI) are among the most promising approaches to fighting cancer. However, a substantial percentage of patients experience off-target adverse effects in the form of mild to severe inflammation in different organs, commonly called immune-related adverse events (irAEs). irAEs can lead to treatment discontinuation, or can be life-threatening in extreme cases. The causes of irAEs are largely unknown and there are no reliable predictive biomarkers. The Montreal Immune-Related Adverse Events (MIRAE) study collects clinical information and biospecimens (blood, tissue, stool) from cancer patients treated with ICI to facilitate research on the identification of predictive biomarkers of irAEs, their causes, and the design of effective management strategies.
Many recent studies have shown that surgical trauma will result in an immunosuppressive state. Combined with the effect of surgical stress, it will often lead to metabolic changes, systemic inflammatory response, and other problems. The body resists and removes the harmful factors through the inflammatory reaction. However, an excessive reaction will damage the normal tissues and cells of the body. The smooth recovery of the body needs to balance the degree of inflammatory reaction. Surgical patients will trigger different degrees of an inflammatory response due to different degrees of physical trauma, which runs through the process of postoperative recovery from the beginning of surgery and often prolongs the time of postoperative recovery. Reducing the intraoperative and postoperative inflammatory response of patients has always been the goal of surgeons, and a method is the reduction of surgical trauma. The successful experience of the first single-port thoracoscopic wedge resection of the lung in 2004 provided us with a new surgical idea. Subsequently, a large number of domestic and international studies and case reports show that single-port thoracoscopic surgery is safe and feasible in lobectomy and segmental resection. With the rapid development of single-port thoracoscopic surgery in recent years, the scope of application and clinical efficacy of the surgery are gradually becoming equivalent to the traditional three-port thoracoscopic surgery, which can ensure the safety of the operation and complete tumor resection, and has its own characteristics and advantages compared with the traditional three-port thoracoscopic surgery. The reduction of incisions can significantly improve the postoperative pain and recovery of patients and wound healing. In addition, single-port thoracoscopic surgery also has a subtle improvement in patients' intraoperative and postoperative inflammatory response compared with traditional three-port thoracoscopic surgery. In this study, we compared and analyzed the intraoperative and postoperative inflammatory factor levels of single-port thoracoscopic surgery and three-port thoracoscopic surgery in patients with non-small cell lung cancer (NSCLC). Through the comparison of the measured values, we further discussed the advantages of single-port thoracoscopic surgery in reducing inflammatory response and its application and promotion value in the treatment of patients with NSCLC compared with traditional three-port thoracoscopic surgery.
By the end of 2019 a new coronavirus, named SARS-CoV-2, was discovered in patients with pneumonia in Wuhan, China. In the following weeks and months the virus spread globally, having a tremendous impact on global health and economy. To date, no vaccine or therapy is available. Severe courses of the infection not only affect the lungs, but also other organs like the heart, kidney, or liver. The lack of preexisting immunity might at least partially explain the affection of extra pulmonary organs not yet seen in infections due to other respiratory viruses. In this observational investigation the study group will follow up on patients that have been hospitalized due to a SARS-CoV-2 infection, and monitor sequelae in various organs, with an emphasis on the pulmo-cardiovascular system. Our that in some patients, organ damage will persist and require long-term medical care.
The purpose of this study is to obverse the effect of this type lens in the same as traditional aspheric intraocular lens at the same time, whether can further improve the effects of operation.
