RESUMEN
The North Carolina Medical Society (NCMS) and American Medical Association (AMA) collaborated to support diabetes prevention efforts in North Carolina (NC) with a physician champion initiative focused on tracking and increasing referrals to the National Diabetes Prevention Program (DPP). Three focus areas to effectively engage and utilize physician champions included: (1) self-adoption within their practice, (2) engagement and outreach with other healthcare leaders, and (3) influence to peers and colleagues. Six NC physician champions were selected to support the work from January 2020 to January 2023. This resulted in increased outreach to physicians about Diabetes Free NC, increased materials/education for physicians on prediabetes identification and management, and 1943 referrals to the National DPP. This work can be further translated and applied to other states to aid prevention efforts. Physician champions' expertise coupled with adequate resources can allow them to play a key role in chronic disease prevention and management.
RESUMEN
Given the proven benefits of screening to reduce diabetic ketoacidosis (DKA) likelihood at the time of stage 3 type 1 diabetes diagnosis, and emerging availability of therapy to delay disease progression, type 1 diabetes screening programs are being increasingly emphasized. Once broadly implemented, screening initiatives will identify significant numbers of islet autoantibody-positive (IAb+) children and adults who are at risk for (confirmed single IAb+) or living with (multiple IAb+) early-stage (stage 1 and stage 2) type 1 diabetes. These individuals will need monitoring for disease progression; much of this care will happen in nonspecialized settings. To inform this monitoring, JDRF, in conjunction with international experts and societies, developed consensus guidance. Broad advice from this guidance includes the following: 1) partnerships should be fostered between endocrinologists and primary care providers to care for people who are IAb+; 2) when people who are IAb+ are initially identified, there is a need for confirmation using a second sample; 3) single IAb+ individuals are at lower risk of progression than multiple IAb+ individuals; 4) individuals with early-stage type 1 diabetes should have periodic medical monitoring, including regular assessments of glucose levels, regular education about symptoms of diabetes and DKA, and psychosocial support; 5) interested people with stage 2 type 1 diabetes should be offered trial participation or approved therapies; and 6) all health professionals involved in monitoring and care of individuals with type 1 diabetes have a responsibility to provide education. The guidance also emphasizes significant unmet needs for further research on early-stage type 1 diabetes to increase the rigor of future recommendations and inform clinical care.

RESUMEN
AIM: There are limited data to evaluate hospitalization for heart failure (hHF) in non-Hispanic Black (hereafter Black) or non-Hispanic White (hereafter White) individuals without previous hHF. Our goal was to evaluate the risk of hHF among Black versus White patients with type 2 diabetes (T2DM) who were initially prescribed empagliflozin using real-world data. METHODS: This multicentre retrospective cohort study included participants aged ≥18 years who had T2DM, were either Black or White, had no previous hHF, and were prescribed empagliflozin between August 2014 and December 2019. Our primary outcome was time to first hHF after the initial prescription of empagliflozin. A propensity-score (PS)-weighted analysis was performed to balance characteristics by race. The inverse probability treatment weighting method based on PS was used to make treatment comparisons. To compare Black with White, a PS-weighted Cox's cause-specific hazards model was used. RESULTS: In total, 8789 participants were eligible for inclusion (Black = 3216 vs. White = 5573). The Black cohort was significantly younger, had a higher proportion of females, and had a higher prevalence of chronic kidney disease, hypertension and diabetic retinopathy, while the White cohort had a higher prevalence of coronary artery disease. After adjustment for confounding factors such as age, gender, coronary artery disease, hypertension and diabetic retinopathy, the hazard ratio for first-time hHF was not significantly different between the two racial groups [hazard ratio (95% confidence interval) = 1.09 (0.84-1.42), p = .52]. CONCLUSION: This study showed no significant difference in incident hHF among Black versus White individuals with T2DM following a prescription for empagliflozin.

Sodium dodecyl sulfate (SDS)-capped 1-pyrenecarboxaldehyde nanoparticles (PyalNPs) were prepared using a reprecipitation method in an aqueous medium and exhibited red-shifted aggregation-induced enhanced emission (AIEE). The dynamic light scattering (DLS) examination showed narrower particle size distribution with an average particle size of 41 nm, whereas -34.5 mV zeta potential value indicate the negative surface charge and good stability of nanoparticles (NPs) in an aqueous medium. The AIEE was seen at λmax = 473 nm in a fluorescence spectrum of a PyalNP suspension. In the presence of Cu2+ ions, the fluorescence of PyalNPs quenches very significantly, even in the presence of other metal ions like Ba2+ , Ca2+ , Cd2+ , Co2+ , Al3+ , Fe2+ , Hg2+ , Ni2+ and Mg2+ . The changes in the fluorescence lifetime of PyalNPs in the presence of Cu2+ ions suggested that the type of quenching was dynamic. The fluorescence quenching data for the NPs suspension fitted well into a typical Stern-Volmer relationship in the concentration range 1.0-25 µg/ml of Cu2+ ions. The estimated value of the correlation coefficient R2 = 0.9877 was close to 1 and showed the linear relationship between quenching data and Cu2+ ion concentration. The limit of detection (LOD) was found to be 0.94 ng/ml and is far below the tolerable intake limit value of 1.3 µg/ml accepted by the World Health Organization for Cu2+ ions in drinking water. The fluorescence quenching approach for a SDS-capped Pyal nanosuspension for copper ion quantification is of high specificity and coexisting ions were found to interfere very negligibly. The developed method was successfully applied for the estimation of copper ions in river water samples.

BACKGROUND/OBJECTIVE: Because racial disparities in hypertension treatment persist, the objective of the present study was to examine patient vs. practice characteristics that influence antihypertensive selection and treatment intensity for non-Hispanic Black (hereafter "Black") patients with uncontrolled hypertension in the rural southeastern USA. METHODS: We enrolled 25 Black patients from each of 69 rural practices in Alabama and North Carolina with uncontrolled hypertension (systolic blood pressure (BP) ≥ 140 mm Hg) in a 4-arm cluster randomized trial of BP control interventions. Patients' antihypertensive medications were abstracted from medical records and reconciled at the baseline visit. Treatment intensity was computed using the defined daily dose (DDD) method of the World Health Organization. Correlates of greater antihypertensive medication intensity were assessed by linear regression modeling, and antihypertensive medication classes were compared by baseline systolic BP (SBP) level. RESULTS: A total of 1431 patients were enrolled and had complete baseline data. Antihypertensive treatment intensity averaged 3.7 ± 2.6 equivalent medications at usual dosages and was significantly related to higher baseline systolic BP, older age, male sex, insurance availability, higher BMI, and concurrent diabetes, but not to practice type or medication barriers in regression models. Renin-angiotensin system inhibitors were the most commonly used medications, followed by diuretics and calcium channel blockers. CONCLUSION/RELEVANCE: Antihypertensive treatment intensity for Black patients in the rural southeastern USA with a history of uncontrolled hypertension averaged the equivalent of almost four medications at usual dosages and was significantly associated with baseline SBP levels and other patient characteristics, but not clinic type. TRIAL REGISTRATION: ClinicalTrials.gov NCT02866669.

PURPOSE: The integration of diabetes technology into diabetes care and self-management is evolving so rapidly that providing sufficient support has become an obstacle for many health care professionals (HCPs) in practice. Diabetes technology requires HCPs to stay current with treatment goals and practice guidelines. Diabetes care and education specialists (DCESs) are well positioned to take on this challenge by seizing opportunities to apply their skills, knowledge, and experience to contribute to a technology-enabled practice environment. Diabetes technology includes devices, hardware, and software utilized to manage all aspects of diabetes care, including lifestyle management, glucose monitoring, and insulin delivery. The complexities of caring for persons with diabetes (PWD) who utilize diabetes technology is best accomplished in partnership with other members of the care team and support staff to cover all aspects of technology including prior authorizations, onboarding PWD, downloading and interpreting data, and supporting ongoing utilization. The purpose of this article is to introduce a comprehensive set of role-based competencies for HCPs, DCESs, and staff for the selection, implementation, and sustainability of diabetes technology when providing diabetes care, education, and support. The role-based competencies described in this article are intended to support the initiation, continuation, and optimal use of diabetes technology in practice through ongoing education and guidance of care team members. CONCLUSION: This article describes the diabetes technology competencies essential for all levels of the care team and support staff in various care settings to deliver comprehensive diabetes management and support to PWD utilizing diabetes technology in their self-care regimen.

PURPOSE: The purpose of this study was to construct professional competencies for diabetes technology use in various care settings reflecting the mission of the Association of Diabetes Care & Education Specialists (ADCES). METHOD: ADCES convened a core team of nationally representative diabetes technology experts to develop professional competencies specifically related to diabetes technology use. A modified Delphi methodology, which comprised 4 rounds, was used for consensus development among these experts. First, experts developed and arrived at a consensus on the initial draft of competencies. They also identified health care professionals and staff essential for effective technology integration in various diabetes care settings. A survey was completed by diabetes technology experts that are members of ADCES. Next, a multidisciplinary focus group was conducted to gain feedback. Finally, the edited competencies were distributed via survey for feedback by diabetes technology experts from various disciplines. RESULTS: One hundred four diabetes technology experts in the United States participated in the final survey, representing various health care professions and clinical settings. A final set of 94 competencies across 7 domains was determined. CONCLUSION: Modified Delphi methodology is an effective way to utilize multidisciplinary expertise to develop diabetes technology-related competencies for diabetes care professionals and staff in a variety of settings. These competencies align with the mission of ADCES to empower diabetes care and education specialists to expand the horizons of innovative education, management, and support.

Type of diabetes is not always straightforward at presentation. Misdiagnosis is common in all age groups and diagnosis becomes evident over time. Patients with latent autoimmune diabetes in adults constitute up to 12% of all patients with diabetes, and they share immunogenetic and phenotypic features of type 1 and type 2 diabetes mellitus. They are commonly misdiagnosed as having type 2 diabetes mellitus, resulting in a delay in initiating insulin. Patients with ketosis-prone diabetes mellitus are often misdiagnosed as having type 1 diabetes mellitus. Correct diagnosis helps wean patients off of insulin and use noninsulin agents if needed.

Pilon fractures are intra-articular injuries involving the tibial plafond and have a wide range of complexity. The timing and type of fixation in these injuries is dictated by soft tissue status and energy imparted to the distal tibial plafond. We had a unique clinical situation in which axial loading of the talus caused severe comminution of the tibial plafond and fracture of the distal third of the fibula. Further action of these forces caused displacement of the fibular segment into dorsum of the foot along with part of the articular surface of the tibial plafond without causing any external wound. This case was challenging because displacement of the distal fibula resulted in disruption of important syndesmotic and lateral ankle ligaments. Fibular segment was without any soft tissue attachment and was reimplanted in the ankle mortise like a free fibula graft. Near normal ankle biomechanics were achieved in this case through anatomic reduction of the articular surface, reimplantation of the fibula in the ankle mortise, and repair of syndesmotic and lateral ankle ligaments. There was satisfactory clinical and radiological outcome on follow-up of more than 4 years. To our knowledge, this is the only case in Standard English literature where in the case of pilon fracture, the fibula had displaced in the foot without external wound.

OBJECTIVES: To assess (1) the willingness to get a COVID-19 vaccine among Medicare beneficiaries, (2) the associated factors, and (3) the reasons for vaccine hesitancy. METHODS: Data were taken from the Medicare Current Beneficiary Survey (MCBS) 2020 Fall COVID-19 Supplement, conducted October-November 2020. Willingness to get a COVID-19 vaccine was measured by respondents' answer to whether they would get a COVID-19 vaccine when available. We classified responses of "definitely" and "probably" as "willing to get," and responses "probably not," "definitely not," and "not sure" as "vaccine hesitancy." Reasons for vaccine hesitancy were assessed by a series of yes/no questions focusing on 10 potential reasons. The analytical sample included 6715 adults 65 years and older. We conducted a logistic regression model to assess demographic factors and other factors associated with the willingness to get a COVID-19 vaccine. All analyses were conducted in Stata 14 and accounted for the complex survey design of MCBS. RESULTS: Overall, 61.0% (95% confidence interval [CI], 59.1-63.0) of Medicare beneficiaries would be willing to get a vaccine when available. Among those who were hesitant, more than 40% reported that mistrust of the government and side effects as the main reasons. Logistic regression model results showed that non-Hispanic Blacks (adjusted odds ratio [AOR] = 0.33; 95% CI, 0.24-0.44) and Hispanics (AOR = 0.60; 95% CI, 0.47-0.77) were less willing to get a vaccine than non-Hispanic Whites; beneficiaries with an income of less than $25 000 (AOR = 0.71; 95% CI, 0.62-0.81) were less willing to get the vaccine than those with an income of $25 000 or more; those who did not think that the COVID-19 virus was more contagious (AOR = 0.53; 95% CI, 0.41-0.69) or more deadly (AOR = 0.51; 95% CI, 0.41-0.65) were also less willing to get the vaccine than those who thought that the virus was more contagious or more deadly than the influenza virus. CONCLUSIONS: The 2020 MCBS survey data showed that close to 40% of Medicare beneficiaries were hesitant about getting a COVID-19 vaccine, and the hesitancy was greater in racial/ethnic minorities. Medicare beneficiaries were concerned about the safety of the vaccine, and some appeared to be misinformed. Evidence-based educational and policy-level interventions need to be implemented to further promote COVID-19 vaccination.

Fluorescent 3-[(E)-(2-phenylhydrazinylidene) methyl]-1H-indole (PHI) was synthesized by condensation of indole-3-carboxaldehyde and phenyl hydrazine in presence of acetic acid and ethanol and after spectral characterization used further to prepare its aqueous nano suspension by reprecipitation method using polyvinylpyrrolidone (PVP) as stabilizer. The average particle size of nano suspension measured by Dynamic Light Scattering (DLS) was found 77.5 nm while FESEM microphotograph showed spherical morphology. The blue shift in the absorption spectrum and stokes shifted fluorescence of nanosuspension of PHI compared to its monomer spectrum in dilute solution indicate formation of H-type aggregate by face to face overlapping of the molecules.The aggregation induced enhanced emission (AIEE) of PVP capped nanosuspension of PHI is increased appreciably by presence of aqueous solution of human serum albumin (HSA). A suitable mechanism of molecular binding interactions based on complex formation between PHI nanoaggregate and HSA through PVP is proposed. Fluorescence life time, zeta potential and particle size data of PHI nanoparticles (PHINPs) obtained in presence of different amounts of HSA are in support of molecular interactions leading to complex formation. The molecular docking studies showed that HSA and PVP capped PHINPs exhibit strong hydrogen bonding interaction. The fluorescence enhancement effect induced in PHI nanosuspension is used further to develop analytical method for quantitative estimation of HSA in aqueous biological sample solution.

OBJECTIVE: To examine if the association between higher A1C and risk of cardiovascular disease (CVD) among adults with and without diabetes is modified by racial residential segregation. RESEARCH DESIGN AND METHODS: The study used a case-cohort design, which included a random sample of 2,136 participants at baseline and 1,248 participants with incident CVD (i.e., stroke, coronary heart disease [CHD], and fatal CHD during 7-year follow-up) selected from 30,239 REasons for Geographic And Racial Differences in Stroke (REGARDS) study participants originally assessed between 2003 and 2007. The relationship of A1C with incident CVD, stratified by baseline diabetes status, was assessed using Cox proportional hazards models adjusting for demographics, CVD risk factors, and socioeconomic status. Effect modification by census tract-level residential segregation indices (dissimilarity, interaction, and isolation) was assessed using interaction terms. RESULTS: The mean age of participants in the random sample was 64.2 years, with 44% African American, 59% female, and 19% with diabetes. In multivariable models, A1C was not associated with CVD risk among those without diabetes (hazard ratio [HR] per 1% [11 mmol/mol] increase, 0.94 [95% CI 0.76-1.16]). However, A1C was associated with an increased risk of CVD (HR per 1% increase, 1.23 [95% CI 1.08-1.40]) among those with diabetes. This A1C-CVD association was modified by the dissimilarity (P < 0.001) and interaction (P = 0.001) indices. The risk of CVD was increased at A1C levels between 7 and 9% (53-75 mmol/mol) for those in areas with higher residential segregation (i.e., lower interaction index). In race-stratified analyses, there was a more pronounced modifying effect of residential segregation among African American participants with diabetes. CONCLUSIONS: Higher A1C was associated with increased CVD risk among individuals with diabetes, and this relationship was more pronounced at higher levels of residential segregation among African American adults. Additional research on how structural determinants like segregation may modify health effects is needed.

OBJECTIVES: Our aim in this study was to determine whether a cognitive-behavioural therapy plus small changes lifestyle intervention can produce comparable improvements in insulin users vs patients not using insulin with uncontrolled type 2 diabetes (T2D) and comorbid depressive or regimen-related distress (RRD) symptoms. METHODS: This study is a secondary analysis of Collaborative Care Management for Distress and Depression in Rural Diabetes Study, a randomized, controlled trial of a 16-session, severity-tailored cognitive-behavioural therapy plus small changes lifestyle intervention compared with usual care. Outcomes included glycated hemoglobin (A1C), regimen-related distress, depression, medication adherence and diabetes self-care. Our investigation provides 2 sets of contrasts: 1) insulin users in the intervention group compared with insulin users in the usual-care group and 2) insulin users compared with noninsulin users in the intervention group only. RESULTS: Of the 139 participants, 72 (52%) were using insulin at baseline and had significantly higher levels of A1C (10.2±2.1% vs 8.9±1.6%) and RRD (3.3±1.4 vs 2.8±1.1), and significantly poorer medication adherence (5.2±2.1 days/wk vs 5.5±1.7 days/wk). Intervention patients using insulin exhibited significantly greater reductions in RRD and marginally significant improvements in medication adherence and A1C compared with insulin users in usual care. Within the intervention group, changes in RRD, medication adherence and A1C did not differ significantly by insulin use. CONCLUSIONS: Tailored cognitive-behavioural therapy with a small-changes lifestyle intervention improved elevated RRD and A1C outcomes at least as effectively in insulin users as nonâinsulin users. Future powered studies need to address the role of insulin use in uptake and treatment outcomes.

Thin films of p-terphenyl luminophors doped by varying amounts of anthracene were prepared by using spin coating technique. The morphological, structural, and photophysical investigation of thin films of p-terphenyl as a function of anthracene concentration is studied by using scanning electron microscopy (SEM), X-ray diffraction (XRD), fluorescence spectroscopy and fluorescence microscopy. The results of XRD and SEM studies indicated that the doped p-terphenyl thin film is homogeneous as compared with a bare p-terphenyl thin film. The fluorescence spectroscopy results indicate complete quenching of p-terphenyl fluorescence and simultaneous sensitization of blue anthracene like emission towards the red side of the spectrum with maximum intensity at 410 nm. The blue intense emission of anthracene seen in fluorescence microscopy images is in agreement with observed fluorescence spectral results. A suitable mechanism of excitation energy transfer (EET) from p-terphenyl to anthracene molecules is proposed and discussed on the basis of energy level diagram. The efficient EET is believed to occur by the orientation of phenyl rings of p-terphenyl in excited state. As the concentration of doped anthracene increases, the fluorescence intensity of doped p-terphenyl and Full Width at Half Maximum (FWHM) found to be increased. The p-terphenyl film containing 0.65 moles of anthracene is of FWHM as low as 28.51 nm. Such narrow band blue emitting doped luminophors are of demand in light emitting diodes (OLED) and scintillation applications.
RESUMEN
Our aim was to explore whether the baseline hemoglobin A1c or the dose of sodium glucose cotransporter-2 inhibitor (SGLT-2i) chosen better predicted the efficacy of SGLT-2i versus dipeptidyl peptidase-4 inhibitor (DPP-4i) in type 2 diabetes. We searched for randomized trials that compared SGLT-2i with DPP-4i in type 2 diabetes and reported a change in hemoglobin A1c over time. We created 2 separate analyses (one based on baseline hemoglobin A1c and the other according to US Food and Drug Administration [FDA]-approved SGLT-2i dose). Thirteen trials were included. In the analysis according to baseline hemoglobin A1c , there was a significantly greater reduction in hemoglobin A1c when baseline hemoglobin A1c was ≥8.5%, favoring SGLT-2i over DPP-4i but not when baseline hemoglobin A1c was <8.5% (mean difference [95%CI], -0.36% [-0.53% to -0.18%] and 0.04% [-0.09% to 0.17%], respectively). On restricting the analysis to trials stratifying hemoglobin A1c to <8.0% or ≥8.0%, results did not change. In the analysis based on FDA-approved SGLT-2i doses, higher SGLT-2i doses caused a significantly greater hemoglobin A1c reduction at ≤26 and ≥52 weeks compared with the highest DPP-4i doses (mean difference [95%CI], -0.11% [-0.18% to -0.04%] and -0.24% [-0.34% to -0.15%], respectively). Lower SGLT-2i doses caused a significantly greater hemoglobin A1c reduction at ≥52 weeks but not at ≤26 weeks compared with the highest DPP-4i doses (mean difference [95%CI], -0.12% [-0.23% to -0.02%] and 0.01% [-0.05% to 0.07%], respectively). In people with type 2 diabetes and a baseline hemoglobin A1c ≥ 8.0%, SGLT-2i produced significantly greater reductions in hemoglobin A1c compared with DPP-4i and may be preferred. SGLT-2i dose titration to a higher FDA-approved dose is recommended in suitable patients.

In people with type 2 diabetes with evidence of obesity-related insulin resistance, use of insulin to treat hyperglycemia has not been shown to reduce macrovascular complications, despite widespread use for many years. However, newer classes of diabetes medications, designed to address the prevalent pathophysiologic defect of type 2 diabetes, have emerged. Consequently, in many patients, reduction of insulin doses or even total elimination is possible after the addition of these newer agents. The authors suggest a cautious approach in which people with type 2 diabetes and established cardiovascular disease who are on high insulin doses (>1.0 unit/kg/day) be treated with diabetes medications that showed evidence of cardiovascular benefit (such as glucagon-like peptide-1 receptor agonists [GLP-1RAs]), on whom close monitoring is crucial because they may be at particular risk for developing hypoglycemia. This approach can be labor intensive and may be challenging for busy primary care providers for who may have limited time to evaluate and follow the patient. The authors present a case report of adding a GLP-1RA to high insulin doses. If the hemoglobin A1c is <8.0% when GLP-1RA is added, insulin doses should be reduced by 20%. Patients should be monitored at least every 4 weeks initially until it is confirmed there is no hypoglycemia risk. If glycemic targets (defined as fasting or preprandial glucose level between 80 and 130 mg/dl) are consistently achieved, providers may consider proactively reducing insulin doses by 10-20% to avoid hypoglycemia. The authors recommend creating appropriate goals and expectation before initiating this process.
