Attitudes and Behaviors with Diabetes Technology Use in the Hospital: Multicenter Survey Study in the United States.

Objective: To assess the attitudes, behaviors, and barriers with diabetes technology use in the general medicine hospital wards. Research Design and Methods: The authors developed a nonincentivized web-based anonymous survey that captured demographic and practice data regarding continuous subcutaneous insulin infusion (CSII) and continuous glucose monitor (CGM) use in the hospital. Setting: Four large hospital systems in the United States. Results: Among 128 survey respondents, 76%, 10%, and 6% were hospitalists, advanced practice providers, and primary care physicians, respectively. The majority of respondents rated the treatment of inpatient hyperglycemia (96%) and the continuation of CSII during the hospital stay (93%) "important." While most respondents (64%) acknowledged knowing the existence of their institution's policies for CSII use, only 84% of those respondents felt somewhat to very familiar with the policy. The most common barrier to CSII use in the inpatient setting was lack of practitioner (70%) and nursing (67%) knowledge of using the device. With regard to CGM use in the hospital, a minority (28%) of respondents were aware of their institution's CGM policies. Less than half of the providers, 43.8%, stated that, when admitting a patient, they reviewed CGM data to guide insulin dosing. Conclusions: In this US multicenter survey, we found that most inpatient practitioners valued glycemic control, but many were not familiar with institutional policies, had lack of knowledge with CSII, and were not reviewing CGM data.

Real-world Comparison of Afirma GEC and GSC for the Assessment of Cytologically Indeterminate Thyroid Nodules.

CONTEXT: Molecular tests have improved the accuracy of preoperative diagnosis of indeterminate thyroid nodules. The Afirma Gene Sequencing Classifier (GSC) was developed to improve the specificity of the Gene Expression Classifier (GEC). Independent studies are needed to assess the performance of GSC. OBJECTIVE: The aim was to compare the performance of GEC and GSC in the assessment of indeterminate nodules. DESIGN, SETTINGS, AND PARTICIPANTS: Retrospective analysis of Bethesda III and IV nodules tested with GEC or GSC in an academic center between December 2011 and September 2018. Benign call rates (BCRs) and surgical outcomes were compared. Histopathologic data were collected on nodules that were surgically resected to calculate measures of test performance. RESULTS: The BCR was 41% (73/178) for GEC and 67.8% (82/121) for GSC (P < .001). Among specimens with dominant Hürthle cell cytology, the BCR was 22% (6/27) for GEC and 63.2% (12/19) for GSC (P = .005). The overall surgery rate decreased from 47.8% in the GEC group to 34.7% in the GSC group (P = .025). One GEC-benign and 3 GSC-benign nodules proved to be malignant on surgical excision. GSC had a statistically significant higher specificity (94% vs 60%, P < .001) and positive predictive value (PPV) (85.3% vs 40%, P < .001) than GEC. While sensitivity and negative predictive value (NPV) dropped with GSC (97.0% vs 90.6% and 98.6% vs 96.3%, respectively), these differences were not significant. CONCLUSIONS: GSC reclassified more indeterminate nodules as benign and improved the specificity and PPV of the test. These enhancements appear to be resulting in fewer diagnostic surgeries.

Macrophage migration inhibitory factor is required for recruitment of scar-associated macrophages during liver fibrosis.

Recruitment of peripheral monocytes to the liver is a key contributor to the response to injury. MIF can act as a chemokine and cytokine, regulating innate immune responses in many tissues and cell types. We hypothesized that MIF contributes to the progression of CCl4-induced hepatic fibrosis by regulating recruitment of SAM. SAMs dynamically regulate HSC activation and ECM degradation. To gain insight into the role of MIF in progression of liver fibrosis, we investigated markers of fibrosis and immune responses after chronic CCl4 administration to female C57BL/6 and MIF(-/-) mice. Chronic CCl4 exposure increased activation of HSC in WT mice, indicated by increased expression of αSMA mRNA and protein, as well as mRNA for collagen 1α1; these responses were blunted in female MIF(-/-) mice. Despite lower activation of HSC in MIF(-/-) mice, accumulation of ECM was similar in WT and MIF(-/-)mice, suggesting a decreased rate of ECM degradation. Recruitment of SAMs was lower in MIF(-/-) mice compared with WT mice, both in their initial inflammatory phenotype, as well as in the later phase as proresolution macrophages. The decreased presence of resolution macrophages was associated with lower expression of MMP13 in MIF(-/-) mice. Taken together, these data indicate that MIF-dependent recruitment of SAMs contributes to degradation of ECM via MMP13, highlighting the importance of appropriate recruitment and phenotypic profile of macrophages in the resolution of fibrosis.
