Exocytosis of peptides and steroids stored in a dense core vesicular (DCV) form is the final step of every secretory pathway, indispensable for the function of nervous, endocrine and immune systems. The lack of live imaging techniques capable of direct, label-free visualisation of DCV release makes many aspects of the exocytotic process inaccessible to investigation. We describe the application of correlative scanning ion conductance and fluorescence confocal microscopy (SICM-FCM) to study the exocytosis of individual granules of insulin from the top, nonadherent, surface of pancreatic β-cells. Using SICM-FCM, we were first to directly follow the topographical changes associated with physiologically induced release of insulin DCVs. This allowed us to report the kinetics of the full fusion of the insulin vesicle as well as the subsequent solubilisation of the released insulin crystal.

Attentional biases to stimuli related to stigmatized appearance are theorized to stem from appearance overvaluation, but little research has examined this link. VIT2763 As well, little research has examined whether appearance overvaluation is associated with biases toward stimuli that describe the attractiveness ideal. We addressed these gaps in the literature using the emotional Stroop task and tested whether appearance overvaluation is associated with an attentional bias for words that describe stigmatized appearance (e.g., fat, ugly, shabby), the attractiveness ideal (e.g., thin, beautiful, fashionable), or both.

In Study 1, a community sample of people (N = 86) completed measures of appearance overvaluation, body dissatisfaction, and body mass index (BMI) followed by an emotional Stroop task. Appearance overvaluation was associated with an attentional bias for attractiveness ideal words-not stigmatized appearance words. Results remained significant when controlling for participants' body dissatisfaction, BMI,ine information processing of stimuli related to the attractiveness ideal among people with eating disorders and who place high importance on appearance for self-definition.Translating patient-reported outcome measures (PROMs) can alter the meaning of items and undermine the PROM's psychometric properties (quantified as cross-cultural differential item functioning [DIF]). The aim of this paper was to present the theoretical background for PROM translation, adaptation, and cross-cultural validation, and assess how PROMs used in sports medicine research have been translated and adapted. We also assessed DIF for the Knee Injury and Osteoarthritis Outcome Score (KOOS) across Danish, Norwegian, and Swedish versions. We conducted a search in PubMed and Scopus to identify the method of translation, adaptation, and validation of PROMs relevant to musculoskeletal research. Additionally, 150 preoperative KOOS questionnaires were obtained from the Scandinavian knee ligament reconstruction registries, and cross-cultural DIF was evaluated using confirmatory factor analysis and Rasch analysis. There were 392 studies identified, describing the translation of 61 PROMs. Ninety-four percent were performed with forward-backward technique. Forty-nine percent used cognitive interviews to ensure appropriate wording, understandability, and adaptation to the target culture. Only two percent were validated according to modern test theory. No study assessed cross-cultural DIF. One KOOS subscale showed no cross-cultural DIF, two had DIF with respect to some (but not all) items, and thus conversion tables could be constructed, and two KOOS subscales could not be pooled. Most PROM translations are of undocumented quality, despite the common conclusion that they are valid and reliable. Scores from three of five KOOS subscales can be pooled across the Danish, Norwegian, and Swedish versions, but two of these must be adjusted for DIF.

Previously published sealant measures are not useful when applied to Medicaid claims data in states where dental services are carved out of managed care. A novel sealant measure was developed to assess the degree to which dental providers seal eligible teeth during preventive dental visits (PDVs) in an effort to ascertain if such a measure can be used to valuate provider performance, as condition of potential value-based care model implementation.

A single-county feasibility study was conducted using Medicaid claims. A study cohort included children aged 8 years and enrolled 12 months during 2018. Prospective analysis was used to determine whether dental sealants were applied by the same dentists during PDVs or up to 9 months thereafter. Eligible teeth included first permanent molars. Teeth previously restored, sealed or missing were excluded. PDV was defined as any encounter with prophylaxis, fluoride treatment, or EPSDT. Claims were compared to public health surveillance for measurement validation.

Single-county results showed 11 percent of eligible teeth were sealed. Only 9 percent of dentists applied sealants to at least 40 percent of eligible teeth. Face validation of sealant rate was 23 percent Medicaid versus 36 percent Public Health. The former measures incidence and the latter prevalence with greater heterogeneity that included partially retained sealants.

A sealant measure that assesses provider adherence to sealant standards of care was produced. It has potential application for assessing performance of pediatric preventive services and informing value-based performance expectations.

This long-term (since 1998) study was on an irrigated clay loam soil in southern Alberta cropped to barley (Hordeum vulgare L.). We sampled the soil 3-4 yr (2017-2018) into the legacy period following 17 annual manure applications (1998-2014). The selected treatments sampled were stockpiled feedlot manure containing straw bedding applied at 0, 13, 39, and 77 Mg ha-1 (dry wt.). Intact soil cores were taken at three depth intervals (0-3, 3-6, and 6-9 cm) in the fall over 2 yr to determine the densities of Acari (mites) suborders and Collembola (springtails) families. Significant (P ≤ .05) application rate effects occurred on Oribatida and Astigmata after 3 yr (but not after 4 yr) into the legacy phase, whereas Prostigmata were unaffected. Densities of Astigmata after 3 yr were 3.2- to 4.1-fold greater at the 77 Mg ha-1 rate compared with three lower rates. Significant application rate effects occurred on Entomobryidae, Isotomidae, and Onychiuridae after 4 yr (but not after 3 yr), with no treatment effects on Neelidae.
