RESUMO
Health care providers may lack data-driven guidance about best practises for discussing weight. We assessed women's self-perception of body mass index (BMI) and preferences for weight counselling by provider characteristics and the initiating question. A voluntary, anonymous survey was completed by 756 women (age ≥ 19 year) at our tertiary care obstetrics and gynaecology clinics in autumn 2021. The respondents' height and weight were collected before respondents selected graphics from a validated Body Image Scale that they felt best represented their current body size and which graphs should prompt weight loss or gain recommendations. Respondents were asked their preferences about provider characteristics for discussion about weight and to identify which of six initiating questions from a provider was most and least preferred. Blank responses were allowed. In 708 responses, 366 women (52%) selected the most accurate graphic that corresponded to their BMI; the selected graphic represented a lower than actual BMI in 268 women (38%) and higher in 74 women (10%). In 648 responses, 374 women (58%) preferred a female provider, but provider body shape, ethnicity/race and age were not important to most women. The most preferred question to initiate a discussion about weight was "A lot of women have trouble achieving or maintaining a healthy weight; is that something we can discuss?" in 181 of 555 women (33%), and the least preferred question was "Do you feel like you are at an appropriate weight?" in 172 of 554 women (31%). Provider knowledge about patient preferences regarding questions may facilitate the discussion about weight.

Background: Sepsis is a life-threatening condition that results from a dysregulated host response to infection, leading to organ dysfunction. Despite the prevalence and associated socioeconomic costs, treatment of sepsis remains limited to antibiotics and supportive care, and a majority of intensive care unit (ICU) survivors develop long-term cognitive complications post-discharge. The present study identifies a novel regulatory relationship between amyloid-ß (Aß) and the inflammasome-caspase-1 axis as key innate immune mediators that define sepsis outcomes. Methods: Medical ICU patients and healthy individuals were consented for blood and clinical data collection. Plasma cytokine, caspase-1 and Aß levels were measured. Data were compared against indices of multiorgan injury and other clinical parameters. Additionally, recombinant proteins were tested in vitro to examine the effect of caspase-1 on a functional hallmark of Aß, namely aggregation. Results: Plasma caspase-1 levels displayed the best predictive value in discriminating ICU patients with sepsis from non-infected ICU patients (area under the receiver operating characteristic curve=0.7080). Plasma caspase-1 and the Aß isoform Aßx-40 showed a significant positive correlation and Aßx-40 associated with organ injury. Additionally, Aß plasma levels continued to rise from time of ICU admission to 7â days post-admission. In silico, Aß harbours a predicted caspase-1 cleavage site, and in vitro studies demonstrated that caspase-1 cleaved Aß to inhibit its auto-aggregation, suggesting a novel regulatory relationship. Conclusions: Aßx-40 and caspase-1 are potentially useful early indicators of sepsis and its attendant organ injury. Additionally, Aßx-40 has emerged as a potential culprit in the ensuing development of post-ICU syndrome.
