Prediabetes (intermediate hyperglycemia) consists of two abnormalities, impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) detected by a standardized 75-gram oral glucose tolerance test (OGTT). Individuals with isolated IGT or combined IFG and IGT have increased risk for developing type 2 diabetes (T2D) and cardiovascular disease (CVD). Diagnosing prediabetes early and accurately is critical in order to refer high-risk individuals for intensive lifestyle modification. However, there is currently no international consensus for diagnosing prediabetes with HbA1c or glucose measurements based upon American Diabetes Association (ADA) and the World Health Organization (WHO) criteria that identify different populations at risk for progressing to diabetes. Various caveats affecting the accuracy of interpreting the HbA1c including genetics complicate this further. This review describes established methods for detecting glucose disorders based upon glucose and HbA1c parameters as well as novel approaches including the 1-hour plasma glucose (1-h PG), glucose challenge test (GCT), shape of the glucose curve, genetics, continuous glucose monitoring (CGM), measures of insulin secretion and sensitivity, metabolomics, and ancillary tools such as fructosamine, glycated albumin (GA), 1,5- anhydroglucitol (1,5-AG). Of the approaches considered, the 1-h PG has considerable potential as a biomarker for detecting glucose disorders if confirmed by additional data including health economic analysis. Whether the 1-h OGTT is superior to genetics and omics in providing greater precision for individualized treatment requires further investigation. These methods will need to demonstrate substantially superiority to simpler tools for detecting glucose disorders to justify their cost and complexity.

Sexual and gender minority (SGM) individuals encompass a broad spectrum of sexual orientations and gender identities. Although SGM is a research term, this population is often known as lesbian, gay, bisexual, transgender, queer (LGBTQ). Typically, LGB refers to sexual orientation, T refers to gender identity, and Q may refer to either. Although each group is distinct, they share the common bond of experiencing health disparities that may be caused, in part, by stigma and discrimination, as well as by the oncology provider"™s lack of knowledge and, therefore, lack of comfort in treating this population. One challenge in improving the quality of care for SGM patients with cancer is the lack of collection of sexual orientation and gender identity (SOGI) data in the medical record. Furthermore, national studies suggest that many oncologists are unsure of what to do with this information, even when it is collected, and some are uncertain as to why they would need to know the SOGI of their patients. This clinical review offers insight into the health disparities experienced by SGM individuals and strategies for improving the clinical encounter and creating a welcoming environment.

BACKGROUND:Hepatitis C virus-positive (HCV+) kidney transplant (KT) recipients are at increased risks of rejection and graft failure. The optimal induction agent for this population remains controversial, particularly regarding concerns that antithymocyte globulin (ATG) might increase HCV-related complications. METHODS:Using Scientific Registry of Transplant Recipients and Medicare claims data, we studied 6780 HCV+ and 139 681 HCV- KT recipients in 1999-2016 who received ATG or interleukin-2 receptor antagonist (IL2RA) for induction. We first examined the association of recipient HCV status with receiving ATG (versus IL2RA) using multilevel logistic regression. Then, we studied the association of ATG (versus IL2RA) with KT outcomes (rejection, graft failure, and death) and hepatic complications (liver transplant registration and cirrhosis) among HCV+ recipients using logistic and Cox regression. RESULTS:HCV+ recipients were less likely to receive ATG than HCV- recipients (living donor, adjusted odds ratio [aOR] = 0.640.770.91; deceased donor, aOR = 0.710.810.92). In contrast, HCV+ recipients who received ATG were at lower risk of acute rejection compared to those who received IL2RA (1-y crude incidence = 11.6% versus 12.6%; aOR = 0.680.820.99). There was no significant difference in the risks of graft failure (adjusted hazard ratio [aHR] = 0.861.001.17), death (aHR = 0.850.951.07), liver transplant registration (aHR = 0.580.971.61), and cirrhosis (aHR = 0.730.921.16). CONCLUSIONS:Our findings suggest that ATG, as compared to IL2RA, may lower the risk of acute rejection without increasing hepatic complications in HCV+ KT recipients. Given the higher rates of acute rejection in this population, ATG appears to be safe and reasonable for HCV+ recipients.

BACKGROUND:The primary objective was to determine the association of patient-reported vision-specific quality of life to disease status and visual function in patients with Friedreich's ataxia (FRDA). METHODS:Patients with FRDA were assessed with the 25-Item National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25) along with measures of disease status (ataxia stage) and visual function (low- and high-contrast letter acuity scores). The relations of NEI-VFQ-25 scores to those for disease status and visual function were examined. RESULTS:Scores for the NEI-VFQ-25 were lower in patients with FRDA (n = 99) compared with published disease-free controls, particularly reduced in a subgroup of FRDA patients with features of early onset, older age, and abnormal visual function. CONCLUSIONS:The NEI-VFQ-25 captures the subjective component of visual function in patients with FRDA.

BACKGROUND:There are safe and well-tolerated level A evidence-based behavioral therapies for the prevention of migraine. They are biofeedback, cognitive behavioral therapy, and relaxation. However, the behavioral therapies for the prevention of migraine are underutilized. OBJECTIVES/OBJECTIVE:We sought to examine whether people with migraine with 4 or more headache days a month had preferences regarding the type of delivery of the behavioral therapy (in-person, smartphone based, telephone) and whether they would be willing to pay for in-person behavioral therapy. We also sought to determine the predictors of likelihood to pursue the behavioral therapy. METHODS:Using a cross-sectional study design, we developed an online survey using TurkPrime, an online survey platform, to assess how likely TurkPrime participants who screened positive for migraine using the American Migraine Prevalence and Prevention screen were to pursue different delivery methods of the behavioral therapy. We report descriptive statistics and quantitative analyses. RESULTS:There were 401 participants. Median age was 34 [IQR: 29, 41] years. More than two thirds of participants (70.3%, 282/401) were women. Median number of headache days/ month was 5 [IQR: 2.83, 8.5]. Some (12.5%, 50/401) used evidence-based behavioral therapy for migraine. The participants reported that they were "somewhat likely" to pursue in-person or smartphone behavioral therapy and behavioral therapy covered by insurance but were neutral about pursuing the telephone-based behavioral therapy. Participants were "not very likely" to pay out of pocket for the behavioral therapy. Migraine-related disability as measured by the MIDAS grading score was associated with likelihood to pursue the behavioral therapy in-person (P = .004), via telephone (P = .015), and via smart phone (P < .001), and covered by insurance (P = .001). However, migraine-related disability was not associated with likelihood to pursue out of pocket (P = .769) behavioral therapy. Pain intensity was predictive of likelihood of pursuing the behavioral therapy for migraine when covered by insurance. Other factors including education, employment, and headache days were not predictors. CONCLUSION/CONCLUSIONS:People with migraine prefer in-person and smartphone-based behavioral therapy to telephone-based behavioral therapy. Migraine-related disability is associated with likelihood to pursue the behavioral therapy (independent of type of delivery of the behavioral therapy-in-person, telephone based or smartphone based). However, participants were not very likely to pay for the behavioral therapy.

PURPOSE OF REVIEW:In 2018-2019, studies were published assessing the effectiveness of reducing HIV incidence by expanding HIV testing, linkage to HIV treatment, and assistance to persons living with HIV to adhere to their medications (the "90-90-90" strategy). These tests of "treatment as prevention" (TasP) had complex results. RECENT FINDINGS:The TasP/ANRS 12249 study in South Africa, the SEARCH study in Kenya and Uganda, and one comparison (arms A to C) of the HPTN 071 (PopART) study in South Africa and Zambia did not demonstrate a community impact on HIV incidence. In contrast, the Botswana Ya Tsie study and the second comparison (arms B to C) of PopART indicated significant ≈ 30% reductions in HIV incidence in the intervention communities where TasP was expanded. We discuss the results of these trials and outline future research and challenges. These include the efficient expansion of widespread HIV testing, better linkage to care, and viral suppression among all persons living with HIV. A top implementation science priority for the next decade is to determine what strategies to use in specific local contexts.

Narrative messages may be superior to didactic messages when providing educational information due to their natural format for information sharing, ability to engage audiences, and engender positive thoughts about the message. Although narrative messages are gaining popularity in health promotion, little guidance exists regarding the development phase. Our team created a psychosocial narrative video intervention grounded in the Health Belief Model to increase breast cancer survivors' attendance at genetic counseling after treatment. Here we report the use of Learner Verification (LV) during an iterative video development process. Using LV, we conducted individual semi-structured interviews with patients and providers, after they viewed the video. Demographic information was analyzed using descriptive statistics, and verbatim interview transcripts were used to conduct a two-phase qualitative content analysis. Patient and provider participants (n = 30) believed the video was attractive, relatable, and informative, and they identified areas for improvement including narrative coherence, changes to text and graphical information, and including more specific information. LV framework elicited audience feedback on the video intervention relevant to theoretical principles of narrative interventions, and highlighted audience preferences. In this study, LV interviews tapped into theoretical constructs of narratives and facilitated the iterative intervention design process.

BACKGROUND:As more older adults undergo surgery, it is critical to understand the long-term effects of surgery on brain health, particularly in relation to the development of Alzheimer's disease. This study examined the association of surgical hospitalization with subsequent brain β-amyloid deposition in nondemented older adults. METHODS:The Atherosclerosis Risk in Communities-Positron Emission Tomography (ARIC-PET) study is a prospective cohort study of 346 participants without dementia who underwent florbetapir PET imaging. Active surveillance of local hospitals and annual participant contact were used to gather hospitalization and surgical information (International Classification of Disease, Ninth Revision, Clinical Modification codes) over the preceding 24-yr period. Brain amyloid measured using florbetapir PET imaging was the primary outcome. Elevated amyloid was defined as a standardized uptake value ratio of more than 1.2. RESULTS:Of the 313 participants included in this analysis (age at PET: 76.0 [SD 5.4]; 56% female), 72% had a prior hospitalization, and 50% had a prior surgical hospitalization. Elevated amyloid occurred in 87 of 156 (56%) participants with previous surgical hospitalization, compared with 45 of 87 (52%) participants who had no previous hospitalization. Participants with previous surgical hospitalizations did not show an increased odds of elevated brain amyloid (odds ratio, 1.32; 95% CI, 0.72 to 2.40; P = 0.370) after adjusting for confounders (primary analysis). Results were similar using the reference group of all participants without previous surgery (hospitalized and nonhospitalized; odds ratio, 1.58; 95% CI, 0.96 to 2.58; P = 0.070). In a prespecified secondary analysis, participants with previous surgical hospitalization did demonstrate increased odds of elevated amyloid when compared with participants hospitalized without surgery (odds ratio, 2.10; 95% CI, 1.09 to 4.05; P = 0.026). However, these results were attenuated and nonsignificant when alternative thresholds for amyloid-positive status were used. CONCLUSIONS:The results do not support an association between surgical hospitalization and elevated brain amyloid.
