BACKGROUND Accidental awareness during general anaesthesia (AAGA) is a complex and rare outcome to investigate in surgical patient populations, particularly obstetric patients. We report the protocol of the Direct Reporting of Awareness in Maternity patients (DREAMY) study, illustrating how the research was designed to address practical and methodological challenges for investigating AAGA in an obstetric cohort. METHODS This is the trial protocol of a prospective, multicentre cohort study of patients undergoing obstetric surgery under general anaesthesia. Accidental awareness during general anaesthesia will be detected using three repetitions of standardised direct questioning over 30 days, with responses indicating memories during general anaesthesia verified using structured interviews. Reports will be adjudicated, then classified, in accordance with pre-defined and pre-validated structures, including the Michigan Awareness Classification tool. Quantitative data will be collected on general anaesthesia conduct for all participants. This descriptive study is being conducted in England and aims to recruit a minimum of 2015 patients. RESULTS The DREAMY study was prospectively registered (ClinicalTrials.gov Identifier NCT03100396) and ethical approval granted. Participant recruitment began in May 2017 and one year follow up concluded in August 2019. Publication of the results is anticipated in 2020. CONCLUSIONS The DREAMY study will provide data on incidence, experience and implications of AAGA for obstetric patients, using a robust methodology that will reliably detect and translate subjective AAGA reports into objective outcomes. In addition, the study is expected to improve vigilance for AAGA in participating hospitals and encourage adoption of recommendations for support of patients experiencing AAGA. Sickle cell disease (SCD) is the most common inherited blood disorder in the United States, and a global health problem. Pathological features of the abnormal hemoglobin (HbS) result in 2 hallmarks of the disease - recurrent episodes of acute microvascular occlusion and chronic hemolytic anemia - that inflict continuous and insidious damage to multiple organs. With improved childhood survival, SCD in adults has evolved into a chronic degenerative disease with underlying damage to multiple organs including the heart and lungs. Cardiopulmonary complications, including cardiomyopathy, diastolic dysfunction, pulmonary hypertension (PH), and sudden cardiac death are the most common causes of morbidity and mortality. Awareness of the sickle-related cardiovascular phenotypes is important for screening, early diagnosis, and intervention of cardiac complications in this disorder. BACKGROUND Historically, adults with ultra short bowel syndrome (USBS) have been considered candidates for lifetime parenteral nutrition (PN) or are referred for visceral transplantation. We examined the surgical and nutritional outcomes of adult patients with USBS managed at a single intestinal rehabilitation center. METHODS We retrospectively reviewed data on 588 adult patients referred to our center between January 2013 and December 2018. USBS was defined as residual small bowel (SB) length ≤ 50 cm. RESULTS Forty-five patients (7.6%) with a mean age of 46.7 years (range 17-78) were identified. Indications for enterectomy included mesenteric ischemia (n=17) and internal hernias (n=6), followed by large intraabdominal fibroids, trauma, and allograft enterectomies, with five cases each. Selleckchem CDK inhibitor Median SB length was 18.0 cm; 20 patients (44.4%) had their entire SB resected. Thirteen patients had an intact colon, of which nine had preservation of the ileocecal valve. Patients who underwent autologous reconstruction of patients followed by our center were still alive (85.7%). CONCLUSION Nutritional autonomy can be achieved in a significant number of patients with USBS in specialized centers with surgical and/or hormonal therapy. The presence of an intact colon and ileocecal valve can significantly increase the adaptation rate. Moreover, restoration of GI tract continuity has a positive impact on medical management and survival. BACKGROUNDS Upfront surgery is the standard treatment for resectable invasive intraductal papillary mucinous carcinoma; however, recurrence is common. Therefore, we investigated the recurrence, surgical outcome, and preoperative prognostic factors for recurrence in patients with resectable invasive intraductal papillary mucinous carcinoma. METHODS We analyzed 111 patients who underwent upfront surgery for resectable invasive intraductal papillary mucinous carcinoma between 2000 and 2017 and evaluated the relationship among clinicopathologic factors, recurrence, and outcomes. RESULTS The 5-year recurrence-free survival and disease-specific survival rates were 61% and 74%, respectively. The median time to recurrence was 1.1 years. In multivariate analysis, carbohydrate antigen 19-9 ≥83 U/mL (hazard ratio 2.8 and 3.1), tumor size ≥2.2 cm (hazard ratio 3.5 and 4.7), and pathologic tubular adenocarcinoma grade 2 (hazard ratio 3.1 and 5.2) were risk factors for a shorter recurrence-free survival and disease-specific survival, respectively. Lymph node metastasis (hazard ratio 3.9) was also a risk factor for a shorter disease-specific survival. When examining outcomes according to preoperatively measurable factors (carbohydrate antigen 19-9 ≥83 U/mL and tumor size ≥2.2 cm), the 5-year recurrence rates in patients with none (n = 47), 1 (n = 46), and both (n = 18) risk factors were 17%, 48%, and 78%, respectively. Five-year disease-specific survival rates in patients with none, 1, and both preoperative risk factors were 95%, 69%, and 31%, respectively. CONCLUSION Carbohydrate antigen 19-9 ≥83 U/mL and tumor size ≥2.2 cm were independent preoperative risk factors for poor outcomes in patients with resectable invasive intraductal papillary mucinous carcinoma. Leonardo da Vinci's analysis and artistic representation of the hepatic vascular anatomy, performed more than 500 years ago, has not yet been fully recognized nor appreciated. Leonardo modified the anatomic concepts of Galen, up until then in vogue, and described for the first time the intrahepatic distribution of the proper hepatic artery, the portal vein, and the hepatic veins. The depiction of these structures is surprising for its clarity and perspective and reproduces the anatomic situation almost exactly. The segmentary division of the liver which several centuries later became the basis of modern resection hepatic surgery was extremely clear in Leonardo's mind.
