Mortality Trends in a Population-based Type 1 Diabetes Cohort

Individuals with type 1 diabetes (T1D) have significantly higher mortality rates than their peers in the general population. Major advances in the management of T1D occurred during the 1980s and 1990s, but recent data on their long-term effects on overall and cause-specific mortality are limited, especially in the United States. A phenomenon, known as dead-in-bed syndrome, is of particular concern as it occurs in young, healthy T1D individuals who are unexpectedly found dead in bed. Using follow-up data from a large population-based cohort, this dissertation provides contemporary mortality rates in persons with long-standing T1D. Cause-specific mortality is also explored, focusing on how mortality rates from major causes compare to the general population and on characterizing T1D deaths that meet the criteria for dead-in-bed syndrome. Overall, the mortality of individuals with T1D is seven times higher than seen in the general population. T1D individuals diagnosed more recently have significantly lower mortality rates than those diagnosed earlier, even after controlling for age. The greatest improvements in mortality have occurred in deaths from diabetes-related causes (diabetic coma, renal disease, cardiovascular disease, or infection), suggesting long-term benefits to improved T1D care. In a pattern quite contrary to what is seen in the general population, females with T1D have a higher mortality than males with T1D, especially from diabetes-related causes. While African-Americans with T1D have much higher mortality rates than T1D Caucasians in this cohort, this racial difference was similar to that seen in the general population. Finally, dead-in-bed syndrome in this population appears associated with male sex, low BMI, and disturbed metabolic control (high HbA1c, high daily insulin dose, and a history of severe hypoglycemia). The public health implications of this dissertation are considerable, as it provides insight into the causes of premature mortality in T1D, permitting the development of more effective and targeted preventative strategies. These findings also have the potential to change routine care practices to address disparities by race and sex in T1D mortality, and resolve disparities in health and life insurance provisions, since antiquated T1D mortality estimates are currently used, which do not account for recent advances in T1D treatments

Phase 3 trials of ixekizumab in moderate-to-severe plaque psoriasis

BACKGROUND Two phase 3 trials (UNCOVER-2 and UNCOVER-3) showed that at 12 weeks of treatment, ixekizumab, a monoclonal antibody against interleukin-17A, was superior to placebo and etanercept in the treatment of moderate-to-severe psoriasis. We report the 60-week data from the UNCOVER-2 and UNCOVER-3 trials, as well as 12-week and 60-week data from a third phase 3 trial, UNCOVER-1. METHODS We randomly assigned 1296 patients in the UNCOVER-1 trial, 1224 patients in the UNCOVER-2 trial, and 1346 patients in the UNCOVER-3 trial to receive subcutaneous injections of placebo (placebo group), 80 mg of ixekizumab every 2 weeks after a starting dose of 160 mg (2-wk dosing group), or 80 mg of ixekizumab every 4 weeks after a starting dose of 160 mg (4-wk dosing group). Additional cohorts in the UNCOVER-2 and UNCOVER-3 trials were randomly assigned to receive 50 mg of etanercept twice weekly. At week 12 in the UNCOVER-3 trial, the patients entered a long-term extension period during which they received 80 mg of ixekizumab every 4 weeks through week 60; at week 12 in the UNCOVER-1 and UNCOVER-2 trials, the patients who had a response to ixekizumab (defined as a static Physicians Global Assessment [sPGA] score of 0 [clear] or 1 [minimal psoriasis]) were randomly reassigned to receive placebo, 80 mg of ixekizumab every 4 weeks, or 80 mg of ixekizumab every 12 weeks through week 60. Coprimary end points were the percentage of patients who had a score on the sPGA of 0 or 1 and a 75% or greater reduction from baseline in Psoriasis Area and Severity Index (PASI 75) at week 12. RESULTS In the UNCOVER-1 trial, at week 12, the patients had better responses to ixekizumab than to placebo; in the 2-wk dosing group, 81.8% had an sPGA score of 0 or 1 and 89.1% had a PASI 75 response; in the 4-wk dosing group, the respective rates were 76.4% and 82.6%; and in the placebo group, the rates were 3.2% and 3.9% (P<0.001 for all comparisons of ixekizumab with placebo). In the UNCOVER-1 and UNCOVER-2 trials, among the patients who were randomly reassigned at week 12 to receive 80 mg of ixekizumab every 4 weeks, 80 mg of ixekizumab every 12 weeks, or placebo, an sPGA score of 0 or 1 was maintained by 73.8%, 39.0%, and 7.0% of the patients, respectively. Patients in the UNCOVER-3 trial received continuous treatment of ixekizumab from weeks 0 through 60, and at week 60, at least 73% had an sPGA score of 0 or 1 and at least 80% had a PASI 75 response. Adverse events reported during ixekizumab use included neutropenia, candidal infections, and inflammatory bowel disease. CONCLUSIONS In three phase 3 trials involving patients with psoriasis, ixekizumab was effective through 60 weeks of treatment. As with any treatment, the benefits need to be weighed against the risks of adverse events. The efficacy and safety of ixekizumab beyond 60 weeks of treatment are not yet known

Incorporating Patient-Reported Outcomes as a Vital Sign for Dermatologic Clinical Care and Clinical Investigations

Patient-reported outcomes (PROs) provide quantitative assessments of patients' experiences with their skin diseases. PROs are usually much more comprehensive than what can be gleaned from a brief clinical history and more informative than what dermatologists can gather on clinical examination. Correlations between PROs and clinician assessments (e.g., investigator global assessment, PASI) are poor to moderate at best, and therefore data from each source are not redundant and can complement one another. PROs should serve as skin vital signs in dermatology. PROs can offer snapshots of the intensity of a symptom as well as the effects of symptoms, emotions, and functioning on a patient's skin-related QOL. Just as clinicians obtain a baseline blood pressure before starting antihypertensives, dermatology-specific PROs serve as a baseline from which clinicians can monitor (even remotely) for improvement or side effects with treatment and for flares. Both PROs and conventional vital signs are usually normal. It is when they are abnormal or different than expected that they become informative. We conclude by offering a roadmap for investigators to conduct the next steps in PRO research necessary to establish guidelines for transitioning PROs from clinical research and trials to routine clinical use

Comprehensive outreach, prevention education, and skin cancer screening for Utah ski resorts

Outdoor recreation can lead to substantial sun exposure. Employees of outdoor recreation establishments with extended time outdoors have amplified cumulative exposure to ultraviolet (UV) radiation and an increased risk of skin cancer. The “Sun Safe on the Slopes” program was created by Huntsman Cancer Institute at the University of Utah and the Utah Cancer Action Network to address increased UV exposure and skin cancer risk with free skin cancer screenings, outreach, and prevention education to local ski resorts. Herein, we describe the processes and barriers to implementation of a ski resort skin screening and education program and our 5-year report of the experience and screening data. Nine free skin cancer screenings were held at Utah ski resorts between 2011 and 2016, resulting in the presumptive diagnosis of 38 skin cancers (9.6%) in 394 participants. Behavioral data collected from participants indicates suboptimal sun safety practices, including underuse of sunscreen and protective clothing. Ski resort employees who experience sun exposure during peak hours at high altitudes and UV reflection from the snow are at an increased risk of skin cancer. These data indicate a need for emphasis on sun safety education and screening and can serve as a model for future endeavors

The continued inappropriate use and overuse of combination topical clotrimazole-betamethasone

Objective: Combination topical clotrimazole/ betamethasone dipropionate (C-BM) contains a high-potency topical corticosteroid and is not infrequently prescribed for inappropriate patient groups and body sites. Use of C-BM can lead to inadequate clearance or exacerbation of fungal infections as well as cutaneous atrophy, striae, and other skin maladies. Methods: We performed a retrospective chart review of 1,978 clinical visits where C-BM was prescribed within the University of Utah Health system between 2014 and 2018 to better understand current prescribing patterns. Results: 1,974 prescriptions were written for C-BM. 91.6% of patients were at least the recommended age of 17 years. C-BM was most commonly prescribed for rashes of an inflammatory (42.2%) or fungal nature (38.1%). Clotrimazole/betamethasone dipropionate was prescribed for sensitive areas (face, axillae, groin or diaper region) in 48.9% of patients. Family medicine clinicians prescribed 58.3% of C-BM prescriptions, whereas dermatology clinicians accounted for 3.4%. Conclusion: We strongly recommend clinicians use alternative treatments for rashes or refer to dermatologists
