本研究の目的は,健康な小児ががんや白血病といった病名からどのようなイメージを抱くのか,自分が大きな病気になったとしたら,病名や治療などについて教えて欲しいと思っているのかを明らかにすることである。千葉県内の小中高校に通っている小学校5年生から高校3年生までの児童生徒1964名から得られたアンケートの回答を,統計ソフトSPSSにて分析を行い以下の結果を得た。1.健康な小児が抱くがんのイメージは,「死ぬ・治らない」「重い・危険・苦しい」といった悲観的なのものが多く,全体の約65%を占めていた。「聞いたことがない・わからない」と答えたものもおり全体の約15%であり,どの学年でも同様の傾向であった。2.健康な小児が抱く白血病のイメージは「病態や特徴について」「原因や治療について」といったものが,全体の約38%を占めていた。「聞いたことがない・わからない」と答えたものは全体の約33%を占め,小学生では半数以上が「聞いたことがない・わからない」と答えていた。3.自分が病気になったときにされる説明については小学生の80%,中学生の85%,高校生の91%が真実を伝えられることを求めていた。その理由として自分の知る権利,治療に前向きに取り組めるといった姿勢の向上,知らないことが不安になる,残された命を有意義に悔いのないように過ごしたいといったものがあげられていた。The purposes of this study were to identify the images of healthy children on cancer and leukemia, and the way of thinking of truth telling with disease. The number of subjects were 1964. They belonged to between the fifth grade of primary school and the third year in high school. They answered someitem-questionnaire, and the answers were analyzed using SPSS. The results were as follows: 1. Sixty-five percent of the images of cancer were pessimistic, like death or incurable and serious or painful . About fifteen percent were having no images. 2. Thirty-eight percent of the images of leukemia were the feature and the cause or the treatment . About thirty-three percent were having no images. 3. Truth telling was desired by eighty percent of students of primary schools, eighty-five percent of junior high schools and ninety-one percent of a high school. The reasons were the rights to know , to be patient with treatments , to become more anxious without truth telling , and to live the remaining days without regrets

Cranberry (Vaccinium macrocarpon) oligosaccharides decrease biofilm formation by uropathogenic Escherichia coli

The preventive effects of the American cranberry (Vaccinium macrocarpon) against urinary tract infections are supported by extensive studies which have primarily focused on its phenolic constituents. Herein, a phenolic-free carbohydrate fraction (designated cranf1b-F2) was purified from cranberry fruit using ion exchange and size exclusion chromatography. MALDI-TOF-MS analysis revealed that the cranf1b-F2 constituents are predominantly oligosaccharides possessing various degrees of polymerisation and further structural analysis (by GC–MS and NMR) revealed mainly xyloglucan and arabinan residues. In antimicrobial assays, cranf1b-F2 (at 1.25 mg/mL concentration) reduced biofilm production by the uropathogenic Escherichia coli CFT073 strain by over 50% but did not inhibit bacterial growth. Cranf1b-F2 (ranging from 0.625 to 10 mg/mL) also inhibited biofilm formation of the non-pathogenic E. coli MG1655 strain up to 60% in a concentration-dependent manner. These results suggest that cranberry oligosaccharides, in addition to its phenolic constituents, may play a role in its preventive effects against urinary tract infections

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
