This international investigation was designed to determine if, and under what circumstances experiences at science centers, significantly correlated with a range of adult general public science and technology literacy measures. Given the complex and cumulative nature of science and technology learning, and the highly variable and free‐choice nature of science center experiences, an epidemiological research approach was used. Quantitative surveys were administered to 6,089 adults living in 17 communities located in 13 countries; all with active science centers. Data collection and analysis protocols ensured a representative sampling based on age, education, and income from each of the 17 participating communities. Results showed that individuals who used science centers had significantly higher understanding, interest and curiosity, participation in free‐choice leisure activities, and identity relative to science and technology than did individuals who did not visit; even when potential self‐selection biases such as income, education level, and prior interest were taken into consideration. These findings significantly strengthen the argument that the presence of one or more healthy and active science centers within a community, region, or country represents a vital investment for fostering and maintaining a scientifically and technologically informed, engaged, and literate public.

Purpose Worldwide, the number of patients waiting for organ transplantation exceeds the number of organs available. Program for uncontrolled donation after circulatory death (uDCD) implemented in Europe has resulted in a 10–15% expansion of the donor pool. We aimed to describe the number of patients eligible for an uDCD program in a regional tertiary care center. Methods We conducted a retrospective cohort study in a Canadian tertiary academic center located in a rural area including all adults who received cardiopulmonary resuscitation in 2016 and died in the emergency department (ED) or during their hospitalization. The primary outcome was the number of patients eligible for uDCD defined as aged between 18 and 60 years old whose collapse was witnessed and where the time between cardiac arrest to cardiopulmonary resuscitation and ED arrival was, respectively, less than 30 and 120 minutes. As a secondary outcome, we determined the number of patients eligible for controlled donation after circulatory death. Results Of the 130 patients included, 84 did not return to spontaneous circulation. We identified 15 potential uDCD candidates, with a mean age of 46.6 (95% Confidence Interval [CI] 41.3 to 52) years. Twelve had an out-of-hospital cardiac arrest with a mean time between collapse and arrival to the ED of 43.2 (29.8 to 56.6) minutes. Among the 46 patients who died after a return of spontaneous circulation, 10 (21.7%) were eligible for organ donation after circulatory death. Conclusion Implementing an uDCD program in a tertiary hospital covering a rural area could increase the number of donors.

paraaortic ones), Stage 3 cancer ovary for pelvic and paraaortic ones. The approach for visualizing lymph nodes starts at the inguinal canal and proceeds towards the diaphragm. A transvaginal examination visualize lymph nodes related to external iliac vessels and the obturator fossa. Results Pathological nodes involved by metastasis has a peripheral or mixed perfusion as an early sign. The shape of an infiltrated lymph node is round, with loss of the hilum sign and inhomogeneous and hypoechogenic. Necrosis, calcification or lymph-node deposits produce a heterogeneous pattern. Later, there is extracapsular growth and irregular margin. Lymph nodes can have a large size more than 2 cm but it is not correlated to malignancy. Nodes are assed based in shape, echogenicity, regularity, homogencity and vascularity. Usually if 2 abnormal signs are seen on ultrasound, this indicates a pathological node apart from size. Conclusion Ultrasound can be used in assessing lymph nodes.
