  2. Background:The Glycemia Risk Index (GRI) was developed in adults with diabetes and is a validated metric of quality of glycemia. Little is known about the relationship between GRI and type 1 diabetes (T1D) self-management habits, a validated assessment of youths’ engagement in habits associated with glycemic outcomes. Method:We retrospectively examined the relationship between GRI and T1D self-management habits in youth with T1D who received care from a Midwest pediatric diabetes clinic network. The GRI was calculated using seven days of continuous glucose monitor (CGM) data, and T1D self-management habits were assessed ±seven days from the GRI score. A mixed-effects Poisson regression model was used to evaluate the total number of habits youth engaged in with GRI, glycated hemoglobin A1c (HbA1c), age, race, ethnicity, and insurance type as fixed effects and participant ID as a random effect to account for multiple clinic visits per individual. Results:The cohort included 1182 youth aged 2.5 to 18.0 years (mean = 13.8, SD = 3.5) comprising 50.8% male, 84.6% non-Hispanic White, and 64.8% commercial insurance users across a total of 6029 clinic visits. Glycemia Risk Index scores decreased as total number of habits performed increased, suggesting youth who performed more self-management habits achieved a higher quality of glycemia. Conclusions:In youth using CGMs, GRI may serve as an easily obtainable metric to help identify youth with above target glycemia, and engagement/disengagement in the T1D self-management habits may inform clinicians with suitable interventions for improving glycemic outcomes.

    The American Institute of Biological Sciences (AIBS) is an umbrella organization of biological societies. In 2020, AIBS developed a plan to intentionally assess its current programs, as well as to develop and expand programs and policies to increase diversity, equity, and inclusion (DEI) in the biological sciences. Therefore, AIBS decided, for the next 5 years, to focus its annual meeting of member societies and organizations, the AIBS Council Meeting, on topics related to DEI. In 2021, AIBS was funded by the National Science Foundation and received additional support from the Doris Duke Charitable Foundation for its expanded annual council meeting, Enabling Scientific Societies to Create Inclusive, Diverse, Equitable, and Accepting (IDEA) Environments. The IDEA conference was created to engage like-minded organizations committed to increasing diversity in the biological sciences. The conference consists of two meetings, an initial virtual 2-day meeting followed by a virtual 1.5-day workshop. The initial meeting included 27 scientific societies with representatives from five minority-serving scientific organizations. This meeting of the IDEA conference, held 4–5 November 2021, served as a call to action that would allow participants to come together to learn, plan, and strategize. This report provides details of the discussions around characteristics of IDEA environments, barriers to creating IDEA environments, strategies to overcome these barriers, and opportunities for action. The agenda can be found within the supplemental material.

  4. Abstract Despite the f0(980) hadron having been discovered half a century ago, the question about its quark content has not been settled: it might be an ordinary quark-antiquark ($${{\rm{q}}}\overline{{{\rm{q}}}}$$ q q ¯ ) meson, a tetraquark ($${{\rm{q}}}\overline{{{\rm{q}}}}{{\rm{q}}}\overline{{{\rm{q}}}}$$ q q ¯ q q ¯ ) exotic state, a kaon-antikaon ($${{\rm{K}}}\overline{{{\rm{K}}}}$$ K K ¯ ) molecule, or a quark-antiquark-gluon ($${{\rm{q}}}\overline{{{\rm{q}}}}{{\rm{g}}}$$ q q ¯ g ) hybrid. This paper reports strong evidence that the f0(980) state is an ordinary$${{\rm{q}}}\overline{{{\rm{q}}}}$$ q q ¯ meson, inferred from the scaling of elliptic anisotropies (v2) with the number of constituent quarks (nq), as empirically established using conventional hadrons in relativistic heavy ion collisions. The f0(980) state is reconstructed via its dominant decay channel f0(980) →π+π, in proton-lead collisions recorded by the CMS experiment at the LHC, and itsv2is measured as a function of transverse momentum (pT). It is found that thenq= 2 ($${{\rm{q}}}\overline{{{\rm{q}}}}$$ q q ¯ state) hypothesis is favored overnq= 4 ($${{\rm{q}}}\overline{{{\rm{q}}}}{{\rm{q}}}\overline{{{\rm{q}}}}$$ q q ¯ q q ¯ or$${{\rm{K}}}\overline{{{\rm{K}}}}$$ K K ¯ states) by 7.7, 6.3, or 3.1 standard deviations in thepT< 10, 8, or 6 GeV/cranges, respectively, and overnq= 3 ($${{\rm{q}}}\overline{{{\rm{q}}}}{{\rm{g}}}$$ q q ¯ g hybrid state) by 3.5 standard deviations in thepT< 8 GeV/crange. This result represents the first determination of the quark content of the f0(980) state, made possible by using a novel approach, and paves the way for similar studies of other exotic hadron candidates.

  5. Abstract Ticks are important vectors of pathogenic viruses, bacteria, and protozoans to humans, wildlife, and domestic animals. Due to their life cycles, ticks face significant challenges related to water homeostasis. When blood‐feeding, they must excrete water and ions, but when off‐host (for stretches lasting several months), they must conserve water to avoid desiccation. Aquaporins (AQPs), a family of membrane‐bound water channels, are key players in osmoregulation in many animals but remain poorly characterized in ticks. Here, we bioinformatically identified AQP‐like genes from the deer tickIxodes scapularisand used phylogenetic approaches to map the evolution of the aquaporin gene family in arthropods. Most arachnid AQP‐like sequences (including those ofI. scapularis) formed a monophyletic group clustered within aquaglycerolporins (GLPs) from bacteria to vertebrates. This gene family is absent from insects, revealing divergent evolutionary paths for AQPs in different hematophagous arthropods. Next, we sequenced the full‐length cDNA ofI. scapularisaquaporin 1 (IsAQP1) and expressed it heterologously inXenopusoocytes to functionally characterize its permeability to water and solutes. Additionally, we examinedIsAQP1expression across different life stages and adult female organs. We foundIsAQP1is an efficient water channel with high expression in salivary glands prior to feeding, suggesting it plays a role in osmoregulation before or during blood feeding. Its functional properties are unique: unlike most GLPs,IsAQP1has low glycerol permeability, and unlike most AQPs, it is insensitive to mercury. Together, our results suggestIsAQP1plays an important role in tick water balance physiology and that it may hold promise as a target of novel vector control efforts.
