ing were observed. Minor complications, mostly hematomas, occurred in 62 patients (7.3%), but they required no further treatment. CONCLUSION Brachial artery access expands our capability to perform complex procedures by allowing us to reach arterial targets in all territories. Complications of brachial vascular access are gradually decreasing together with the decrease of the crossing profile of the devices used in practice. However, when they occur, they often require surgical treatment. The growing experience of the team not only while obtaining the access but also while achieving adequate hemostasis ("patent hemostasis") is of great importance for minimizing the complications. OBJECTIVE To test whether aneurysm biomechanical ratio (ABR; a dimensionless ratio of wall stress and wall strength) can predict aneurysm related events. METHODS In a prospective multicentre clinical study of 295 patients with an abdominal aortic aneurysm (AAA; diameter ≥ 40 mm), three dimensional reconstruction and computational biomechanical analyses were used to compute ABR at baseline. Participants were followed for at least two years and the primary end point was the composite of aneurysm rupture or repair. RESULTS The majority were male (87%), current or former smokers (86%), most (72%) had hypertension (mean ± standard deviation [SD] systolic blood pressure 140 ± 22 mmHg), and mean ± SD baseline diameter was 49.0 ± 6.9 mm. Mean ± SD ABR was 0.49 ± 0.27. Participants were followed up for a mean ± SD of 848 ± 379 days and rupture (n = 13) or repair (n = 102) occurred in 115 (39%) cases. The number of repairs increased across tertiles of ABR low (n = 24), medium (n = 34), and high ABR (n = 44) (p = .010). Rupture or repair occurred more frequently in those with higher ABR (log rank p = .009) and ABR was independently predictive of this outcome after adjusting for diameter and other clinical risk factors, including sex and smoking (hazard ratio 1.41; 95% confidence interval 1.09-1.83 [p = .010]). CONCLUSION It has been shown that biomechanical ABR is a strong independent predictor of AAA rupture or repair in a model incorporating known risk factors, including diameter. Determining ABR at baseline could help guide the management of patients with AAA. OBJECTIVE Numerous studies have shown a paradoxical protective effect of diabetes on the development and progression of abdominal aortic aneurysm (AAA). The aim of this study was to investigate whether the protective role of diabetes on AAA extends to rupture, given the presence of an AAA. METHODS This was a register based case control study. Z-VAD-FMK solubility dmso Patients with ruptured AAA (RAAA) were matched 11 with patients undergoing elective surgery for AAA by sex, age, and year of diagnosis. Multiple conditional logistic regression was performed to estimate the odds ratio (OR) associating a diagnosis of diabetes with RAAA. No protocol was registered. RESULTS From 1996 to 2016, there were 6293 potential people with RAAA. A total of 898 people with a RAAA were excluded since no matching controls existed. This left5 395 cases in the study. The cases had a median age of 75, and 85.4% were men. Diabetes was defined by hospital diagnosis or the redemption of antidiabetic prescriptions within one year. Comparing cases with controls and the presence of diabetes, a significant crude OR of 0.82 (95% confidence interval [CI] 0.71-0.95) was found. When adjusting for confounders OR increased to 0.97 (CI 0.83-1.14). Stratifying by age and year of diagnosis did not change the results markedly. OR associating RAAA with diabetes was significantly elevated in women (adjusted OR 1.82 [CI 1.17-2.81]). Of the 5395 cases, the overall 30 days mortality was 58% (n = 3145). Using Cox regression, a crude hazard ratio (HR) of 1.06 (CI 0.93-1.22) was found for the 30 day mortality and having diabetes compared with not having diabetes. Adjusting for index year, male sex, and age had little effect on this estimate (HR 1.11 [CI 0.97-1.28]). CONCLUSION Diabetes was not found to protect against RAAA, given the presence of an AAA. Furthermore, diabetes did not increase the risk of dying within 30 days of RAAA. Sinusoidal obstruction syndrome (SOS), previously known as veno-occlusive disease, is characterized by concentric and non-thrombotic obstruction of the sinusoid and central vein lumen with no identified primitive or thrombotic hepatic vein lesions. The initial lesion is a result of endothelial denudation, corresponding to the migration of damaged sinusoidal cells to the central veins of the hepatic lobules, leading to sinusoidal and veno-occlusive congestive obstruction. SOS may be associated with other lesions such as centrilobular perisinusoidal fibrosis, peliosis, or nodular regenerative hyperplasia. The first cases of SOS were documented in 1920 in South Africa, after ingestion of food sources contaminated by pyrrolizidine alkaloids. SOS is a well-known complication of hematopoietic stem cell transplantation (HSCT). Numerous toxins and drugs have been associated with SOS, mainly chemotherapies and immunosuppressive therapies, as well as total body or liver irradiation and ABO mismatch platelet transfusion. The pathogenesis of this entity remains unknown. OBJECTIVES To determine the association between physical activity (PA) and subjective cognitive complaints (SCCs), and the influential factors in this association. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS Community-based data of the World Health Survey, which included 248,504 individuals from 47 low- and middle-income countries (LMICs), were analyzed [mean age = 38.6 (standard deviation 16.1) years; 50.7% female]. METHODS PA was assessed with the International Physical Activity Questionnaire. Participants were grouped into those who meet (high PA) the 150 minutes of moderate-to-vigorous intensity PA per week recommendation, and those who do not (low PA). Two questions on subjective memory and learning complaints in the past 30 days were used (scales ranged from 1 to 5, with higher scores representing more severe SCC). Multivariable ordinal logistic regression and mediation analyses were performed. RESULTS Overall, after adjusting for sociodemographic and a wide range of behavioral, psychological, and physical factors, low PA was associated with a higher risk for having more severe subjective memory complaints [odds ratio (OR) = 1.
