Introduction: In spite of increasing diffusion, Enhanced Recovery Pathways (ERP) have been scarcely assessed in large scale programs of lung cancer surgery. The aim of this study was auditing our practice. Methods: A two-step audit program was established: the first dealing with our initial ERP experience in patients undergoing non-extended anatomical segmentectomies and lobectomies, the second including all consecutive patients undergoing all kind of lung resections for NSCLC. The first step aimed at auditing results of ERP on occurrence of postoperative complications and at assessing which ERP components are associated with improved short-term outcomes. We also audited late results by assessing long-term survival of patients in the first step of our study. The second step aimed at auditing on large-scale short-term results of the ERP in a real-life setting. Results: Over a one-year period, 166 patients were included. The median number of ERP procedures per patient was three (IQR 3–4). No postoperative death occurred. The overall adverse events rate was 30%. In multivariate analyzes, the only element associated with reduced adverse postoperative events was chest tube withdrawal within POD2 (OR = 0.21, 95% CI (0.10–0.46)). The 1-, 3-, and 5-year survival rates were 97%, 86.1%, and 76.3%, respectively. In the second period, 1077 patients were included in our ERP; 11 patients died during the postoperative period or within 30 days of operation (1.02%). The overall postoperative adverse event rate was 30.3%, major complication occurring in 134 (12.4%), and minor ones in 192 (17.8%). Respiratory complications occurred in 64 (5.9%). Thoracoscore independently predicted postoperative death, the occurrence of complications (all-kind, minor, major, or respiratory ones). Conclusions: Compliance to ERP procedures and early chest tube removal are associated with reduced postoperative events in patients with lung resection surgery. In a large setting scale, ERP can be applied with satisfactory results in terms of mortality and morbidity. Thoracoscore is a useful tool in predicting mortality and postoperative adverse events.
COVID-19 pandemic has been characterized by a pattern of consecutive declines and regrowth in European countries in 2020. After being partially regressed during the summer, the reappearance of the infection during fall 2020 in many temperate countries strongly suggests that temperature and cold may play a role in influencing the infectivity and virulence of SARS-CoV-2. While promoting medicine as an art, Hippocrates interpreted with logical reasoning the occurrence of diseases such as epidemics, as a consequence of environmental factors, in particular climatic variations. During the Renaissance, Sanctorius was one of the first to perform quantitative measurements, and Harvey discovered the circulation of blood by performing experimental procedures in animals. We think that a reasoning mixing various observations, measurements and experiments is fundamental to understand how cold increases infectivity and virulence of SARS-CoV-2. By this review, we provide evidence linking cold, angiotensin-II, vasoconstriction, hypoxia and aerobic glycolysis (the Warburg effect) to explain how cold affects the epidemiology of COVID-19. Also, a low humidity increases virus transmissibility, while a warm atmosphere, a moderate airway humidity, and the production of vasodilator angiotensin 1-7 by ACE2 are less favorable to the virus entry and/or its development. The meteorological and environmental parameters impacting COVID-19 pandemic should be reintegrated into a whole perspective by taking into account the different factors influencing transmissibility, infectivity and virulence of SARS-CoV-2. To understand the modern enigma represented by COVID-19, an interdisciplinary approach is surely essential.
Acute appendicitis is one of the most common causes of abdominal pain at the emergency room. In rare cases, it can be caused by malignancy, even metastatic lesions from extra-abdominal neoplasia. Herein, we report a case of a 64-year-old female with a history of invasive ductal carcinoma of the breast treated by chemotherapy, surgery, radiotherapy and hormonotherapy, relapsing several years later as a bone and a pleura metastasis successfully cured by locoregional therapy and hormonal treatment. She presented with acute abdominal pain without signs of peritonitis. Abdominal computed tomodensitometry showed sign of appendicitis. Therefore, laparoscopic exploration and appendicectomy was performed. During surgery, multiple peritoneal nodules were found and harvested. Pathology showed metastatic nodules of invasive ductal breast carcinoma, including in the appendicular wall, concluding to peritoneal carcinomatosis. The postoperative course was uneventful, but the patient died 1 year later after refusing anticancer treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
