Small intestinal CD103+ dendritic cells display unique functional properties that are conserved between mice and humans

A functionally distinct subset of CD103+ dendritic cells (DCs) has recently been identified in murine mesenteric lymph nodes (MLN) that induces enhanced FoxP3+ T cell differentiation, retinoic acid receptor signaling, and gut-homing receptor (CCR9 and α4β7) expression in responding T cells. We show that this function is specific to small intestinal lamina propria (SI-LP) and MLN CD103+ DCs. CD103+ SI-LP DCs appeared to derive from circulating DC precursors that continually seed the SI-LP. BrdU pulse-chase experiments suggested that most CD103+ DCs do not derive from a CD103− SI-LP DC intermediate. The majority of CD103+ MLN DCs appear to represent a tissue-derived migratory population that plays a central role in presenting orally derived soluble antigen to CD8+ and CD4+ T cells. In contrast, most CD103− MLN DCs appear to derive from blood precursors, and these cells could proliferate within the MLN and present systemic soluble antigen. Critically, CD103+ DCs with similar phenotype and functional properties were present in human MLN, and their selective ability to induce CCR9 was maintained by CD103+ MLN DCs isolated from SB Crohn's patients. Thus, small intestinal CD103+ DCs represent a potential novel target for regulating human intestinal inflammatory responses

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

An Epilogue

I den bästa av världar [In the best of worlds]Den bästa av dagar [The best of days]Vi slapp ju nazister [We did not have Nazis]Så vad ska vi klaga? [So what should we complain about?] In the above poem, trans* activist and spoken word poet Yolanda Aurora Bohm Ramirez (2018) both names the ways the lives of specific groups of people in Sweden are threatened by the increasing neo-Nazi violence and illuminates the response of the majoritarian population to these threats: their demands of silence where protest and criticism is made nearly impossible

Pluralistic Struggles in Gender Sexuality and Coloniality : Challenging Swedish exceptionalism

This open access book seeks to understand how politics is being made in a pluralistic sense, and explores how these political struggles are challenging and transforming gender, sexuality, and colonial norms. As researchers located in Sweden, a nation often cited as one of the most gender-equal and LGBTQ-tolerant nations, the contributions investigate political processes, decolonial struggles, and events beyond, nearby, and in between organizations, states, and national territories. The collection represents a variety of disciplines, and different theoretical conceptualizations of politics, feminist theory, and postcolonial and queer studies. Students and researchers with an interest of queer studies, gender studies, critical whiteness studies, and civil society studies will find this book an invaluable resource
