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

The Future of the Democracy in Cuba

Demokracja na Kubie i jej przyszłość to tematy ważne dla wszystkich tych, którzy Ameryką Łacińską i jej relacjami z Europą się interesują. Jednakże na samej wyspie wydaje się być tematem tabu. Wychodząc od koncepcji demokracji promowanej przez międzynarodowe organizacje oraz tej zawartej w Konstytucji Kuby, autor artykułu stara się wskazać obszary, w których mogłyby nastąpić zmiany idące ku demokratyzacji systemu na wyspie a także odpowiedzieć na pytanie jak w przyszłości będzie wyglądać demokracja w tym kraju.Democracy in Cuba and its future are the important topics to all those who are interested in Latin America and its relations with Europe. On the same island, one can say, that this subject is a taboo. Starting from the concept of democracy promoted by international organizations as well as that contained in the Constitution of Cuba, the author tries to identify areas where changes could be reach, also responds to the question of how he sees the future of democracy in Cuba

Maternal neurotic symptoms and infants' risk of developing persistent diarrhoea Sintomas neuróticos maternos e risco no desenvolvimento de diarréia persistente em crianças

A previously calculated predictive model for health risk selects infants who suffer 4-5 times more morbidity than their unselected peers. Preliminary results suggested that this risk is related to maternal neurotic symptomatology. To evaluate this hypothesis, 52 consecutive mothers whose infants had a positive predictive score (Group 1) and 52 in whom this was negative (Group 2) were evaluated by means of Goldberg's General Health Questionnaire (GHQ - 30). A total of 41.9% and 20.5% of the mothers in Groups 1 and 2, respectively, scored above 11 points in GHQ-30, established as the cut off point. It is concluded that among poor urban families in Santiago mothers of infants with high risk of persistent diarrhoea have increased frequency of detectable neurotic symptoms. New programs aimed at this type of infant should include psychological support for their mothers.<br>Um modelo preditivo previamente calculado para o risco de saúde selecionou crianças que sofriam de 4 a 5 vezes mais de doenças do que seus pares não selecionados. Resultados preliminares sugeriram que esse risco referia-se a sintomas neuróticos maternos. Para avaliar esta hipótese, 52 mães, cuja criança tinha um escore preditivo positivo (grupo 1) e 52 nas quais este escore era negativo (grupo 2), foram avaliados por meio do Questionário de Saúde Geral de Goldberg (GHQ-30). Um total de 41,9% e 20,5% das mães do grupo 1 e 2, respectivamente, tiveram escores acima de 11 pontos no GHQ-30, o qual ficou estabelecido como o ponto de corte. Conclui-se que entre famílias pobres da cidade de Santiago, mães de crianças com alto risco de diarréia persistente tiveram freqüência aumentada de sistemas neuróticos deficitários. Novos programas visando esse tipo de crianças deveriam incluir apoio psicológico para suas mães
