Objective To compare the bacterial spectrums of respiratory intensive care unit (RICU) patients derived from traditional bacterial culture and loop-mediated isothermal amplification (LAMP) assay. To analyze the relationship between clinical factors and clinical outcome of patients. Methods Data of patients in RICU with lower respiratory tract infection from October 2018 to December 2020 was collected. The bacterial spectrums obtained by traditional culture method and LAMP-based method were compared. Clinical factors were divided into two categories and taken into analysis of variance for assessing their relevance with clinical outcomes. Those with significances in analysis of variance were taken into binary logistic regression. Results A total of 117 patients were included. The ratio of patients with positive bacterial culture results was 39.13% (n=115), and that with positive LAMP assay results was 72.65% (n=117). The ratios of patients with at least two positive results for culture and LAMP were 8.70% (n=115) and 36.75% (n=117), respectively. According to chi-squared test, mechanical ventilation (χ2=5.260, P=0.022), and patients with two or more bacteria positive for LAMP assay (χ2=8.227, P=0.004) were related to higher risk of death. Mechanical ventilation and patients with two bacteria positive for LAMP assay were included in binary logistic regression. The odds ratio for death was 4.789 in patients with two or more bacteria positive by LAMP assay (95% confidence interval 1.198 - 19.144, P=0.027). Conclusions LAMP-based method is helpful in detecting more bacteria from respiratory tract specimens of RICU patients, which will be a contributor to precision medicine. Patients with at least two bacteria positive based on LAMP assay have higher risk of death.
Pelvic exenteration has become an important procedure for radical treatment of locally advanced/recurrent rectal cancer, and in recent years, with the advancement of surgical techniques and the improvement of perioperative management ability, the long-term prognosis of patients has been significantly improved. However, the high incidence of perioperative complications seriously impacts the quality of life of patients and the course of postoperative recovery, which remains a major problem for surgeons. Precise surgical levels and appropriate intraoperative position help to fully expose the surgical field, accurately identify major vessels, and reduce the risk of intraoperative bleeding. Biological mesh, myocutaneous flap and omentoplasty are common pelvic floor reconstruction methods, and combined repair of pelvic defects by two of them may further reduce the incidence of empty pelvic syndrome. Iliac revascularization could effectively prevent postoperative thrombosis and ventricular septal syndrome. The application of minimally invasive techniques and the implementation of pre-rehabilitation measures might help to reduce postoperative complications. This article reviews the prevention strategies of complications after pelvic exenteration in order to provide some reference for clinical practice and surgical promotion.
Under the background of a series of national policies, various forms of medical association have been established in recent years. The purpose of the medical association is to promote the coordination and integration of medical services and the rational distribution of medical resources. However, the implementation effect varies greatly. In the process of construction, there are problems such as the unsynchronized coordination and operation between the upper and lower levels, the inadequate integration of resources, the differences and conflicts in information standards and even cultural concepts, which limit the construction effect of the medical association to a certain extent. In order to solve these problems and explore a better path for the construction of medical association, this paper summarizes and analyzes the integrated development and construction measures of “discipline+operation” of the First People’s Hospital of Ziyang under the “government-hospital cooperation”, hoping to provide experience and reference for the construction of medical association to a certain extent through the summary and analysis, thus contributing to the better development of the construction of medical association.
