Suprachoroidal Injection of Triamcinolone Acetonide Injectable Suspension for the Treatment of Macular Edema Associated With Uveitis in the United States: A Cost-Effectiveness Analysis

ObjectivesSuprachoroidal injection of triamcinolone acetonide is the first Food and Drug Administration–approved treatment for macular edema associated with uveitis. A cost-effectiveness analysis was performed comparing this treatment with best supportive care (BSC) for the management of this indication from US Medicare and commercial payer perspectives.MethodsA patient-level simulation was developed per the patient characteristics and changes in best-corrected visual acuity letter scores observed in a phase III study of triamcinolone acetonide (PEACHTREE). The wholesale acquisition cost of triamcinolone acetonide was $1650/injection; suprachoroidal injection cost was assumed at $200/injection. Healthcare costs were informed by a US claims–based analysis. Mortality risk associated with severe vision loss and blindness was modeled by applying a hazard ratio to all-cause mortality rates of the US general population. Health-related quality of life weights, obtained from a regression model fitted to the Visual Function Questionnaire-25 data from PEACHTREE, were applied based on the best-corrected visual acuity scores of both eyes. Costs (2020 US dollar) and benefits were discounted at 3% annually. Incremental cost-effectiveness ratios were estimated over a 10-year horizon.ResultsIn the base-case, the incremental cost-effectiveness ratio comparing triamcinolone acetonide with BSC was $28 479 per quality-adjusted life-year gained. The wholesale acquisition cost for triamcinolone acetonide for suprachoroidal use was ～68%, ～56%, and ～27% below the willingness-to-pay thresholds of $150 000, $100 000, and $50 000 per quality-adjusted life-year gained, respectively. Results were robust in sensitivity and scenario analyses.ConclusionsTriamcinolone acetonide for suprachoroidal use is cost-effective compared with BSC for patients with macular edema associated with uveitis.     

Trends in Vitamin C Consumption in the United States: 1999–2018

Low intakes of fruits and vegetables have resulted in suboptimal intakes of several micronutrients, including vitamin C. This cross-sectional study used data from 84,902 children/adults (≥1 y) who completed a 24-h dietary recall as part of the United States National Health and Nutrition Examination Survey (1999–2018). Mean vitamin C intakes from foods/beverages were calculated as were trends in major food/beverage sources of vitamin C. Percentages below the Estimated Average Requirement (EAR) were estimated. Overall, mean vitamin C consumption declined by 23% (97–75 mg/d; p-value for trend < 0.001). 100% fruit juice was the leading source of vitamin C (25.6% of total or 21.7mg/d), but this declined by 48% (25–13 mg/d; p-value for trend < 0.001). Whole fruit increased among children/adolescents (+75.8%;10–17 mg/d; p-value for trend < 0.001), but not adults, while the vegetable contribution was generally unchanged. The proportion of the population below the EAR increased by 23.8% on a relative scale or 9 percentage points on an absolute scale (38.3–47.4%). Declines in vitamin C intake is driven largely by decreases in fruit juice coupled with modest increases in whole fruit. Due to associations between vitamin C intake and numerous health outcomes these trends warrant careful monitoring moving forward.     

Evaluating Differences in Whole Blood,Serum, and Urine Screening Tests for Zika Virus,Puerto Rico,USA, 2016

We evaluated nucleic acid amplification testing (NAAT) for Zika virus on whole-blood specimens compared with NAAT on serum and urine specimens among asymptomatic pregnant women during the 2015–2016 Puerto Rico Zika outbreak. Using NAAT, more infections were detected in serum and urine than in whole blood specimens.     

Rare Norovirus GIV Foodborne Outbreak,Wisconsin, USA

We report a norovirus GIV outbreak in the United States, 15 years after the last reported outbreak. During May 2016 in Wisconsin, 53 persons, including 4 food handlers, reported being ill. The outbreak was linked to individually prepared fruit consumed as a fruit salad. The virus was phylogenetically classified as a novel GIV genotype.     

Characteristics and Risk Factors of Hospitalized and Nonhospitalized COVID-19 Patients,Atlanta, Georgia,USA, March–April 2020

We compared the characteristics of hospitalized and nonhospitalized patients who had coronavirus disease in Atlanta, Georgia, USA. We found that risk for hospitalization increased with a patient’s age and number of concurrent conditions. We also found a potential association between hospitalization and high hemoglobin A1c levels in persons with diabetes.     

Confirmed Cases of Ophidiomycosis in Museum Specimens from as Early as 1945, United States

Ophidiomycosis represents a conservation threat to wild snake populations. The disease was reported in North America early in the 21st century, but the history of ophidiomycosis has not been investigated. We examined museum specimens and confirmed cases of ophidiomycosis >50 years before the disease’s reported emergence.     

“In the Bible Belt:” The role of religion in HIV care and prevention for transgender people in the United States South

Within the United States South, the socio-religious norms that shape life for many residents may have public health implications. Drawing from 12 key informant interviews, this study explores the role of religious institutions in HIV care and prevention access among transgender people of color in Southern cities. Findings suggest that while religious anti-transgender stigma is pervasive, the regional importance of faith-based beliefs and institutions necessitates targeted faith-based initiatives for the population. Broadly, findings suggest regional environments may demand interventions that negotiate historically marginalizing relationships between at-risk groups and dominant cultural institutions.     

Stigma in place: Black gay men's experiences of the rural South

Black gay men (MSM) in the rural United States South are inequitably burdened by stigmatization and the HIV epidemic. Drawing from twelve oral history interviews with middle-aged and older Black gay narrators from rural North Carolina, this research explores the impact of sexual marginalization and the HIV epidemic on lived experiences of the rural South. Despite describing increasingly empowered views of HIV and sexual health, narrators expressed persistent difficulty managing social determinants of HIV vulnerability—sexual stigma and disconnection from LGBTQ collectivity. Narrators reported better managing sexual marginalization over their lifetimes in urban settings and places outside of the South such as New York (NY). This research suggests stressful structural and interpersonal experiences of stigma may define lived experiences of particular settings.     

Estimate of Burden and Direct Healthcare Cost of Infectious Waterborne Disease in the United States

Provision of safe drinking water in the United States is a great public health achievement. However, new waterborne disease challenges have emerged (e.g., aging infrastructure, chlorine-tolerant and biofilm-related pathogens, increased recreational water use). Comprehensive estimates of the health burden for all water exposure routes (ingestion, contact, inhalation) and sources (drinking, recreational, environmental) are needed. We estimated total illnesses, emergency department (ED) visits, hospitalizations, deaths, and direct healthcare costs for 17 waterborne infectious diseases. About 7.15 million waterborne illnesses occur annually (95% credible interval [CrI] 3.88 million–12.0 million), results in 601,000 ED visits (95% CrI 364,000–866,000), 118,000 hospitalizations (95% CrI 86,800–150,000), and 6,630 deaths (95% CrI 4,520–8,870) and incurring US $3.33 billion (95% CrI 1.37 billion–8.77 billion) in direct healthcare costs. Otitis externa and norovirus infection were the most common illnesses. Most hospitalizations and deaths were caused by biofilm-associated pathogens (nontuberculous mycobacteria, Pseudomonas, Legionella), costing US $2.39 billion annually.     

Novel 6-Month Treatment for Drug-Resistant Tuberculosis,United States

The US Food and Drug Administration approved a 6-month regimen of pretomanid, bedaquiline, and linezolid for extensively drug-resistant or multidrug-intolerant tuberculosis after a trial in South Africa demonstrated 90% effectiveness 6 months posttreatment. We report on a patient who completed the regimen using a lower linezolid dose.
