Effectiveness of telemedicine diabetic retinopathy screening in the USA: a protocol for systematic review and meta-analysis.

Background: Diabetic retinopathy (DR) is the leading cause of vision loss among adults in the USA. Vision loss associated with diabetic retinopathy can be prevented with timely ophthalmologic care, and therefore, it is recommended that individuals with diabetes have annual retinal examinations. There is limited evidence on whether using telemedicine to screen for DR in primary care clinics in the USA effectively leads to increased DR screening rates.

Ranked determinants of telemedicine diabetic retinopathy screening performance in the United States primary care safety-net setting: an exploratory CART analysis.

Background: Diabetic retinopathy (DR) is a leading cause of blindness worldwide, despite easy detection and effective treatment. Annual screening rates in the USA remain low, especially for the disadvantaged, which telemedicine-based DR screening (TDRS) during routine primary care has been shown to improve. Screening rates from such programs have varied, however, pointing to inconsistent implementation and unaddressed barriers.

Evaluation of multi-level barriers and facilitators in a large diabetic retinopathy screening program in federally qualified health centers: a qualitative study.

Background: Recommended annual diabetic retinopathy (DR) screening for people with diabetes has low rates in the USA, especially in underserved populations. Telemedicine DR screening (TDRS) in primary care clinics could expand access and increase adherence. Despite this potential, studies have observed high variability in TDRS rates among clinics and over time, highlighting the need for implementation supports.

Implementation and sustainment of a statewide telemedicine diabetic retinopathy screening network for federally designated safety-net clinics.

Context: Diabetic retinopathy (DR) is the leading cause of incident blindness among working-age adults in the United States. Federally designated safety-net clinics (FDSC) often serve as point-of-contact for patients least likely to receive recommended DR screenings, creating opportunity for targeted interventions to increase screening access and compliance.

Study Design And Methods: With such a goal, we implemented and assessed the longitudinal performance of an FDSC-based telemedicine DR screening (TDRS) network of 22 clinical sites providing nonmydriatic fundus photography with remote interpretation and reporting.

Human Papillomavirus Prevalence Is Associated With Socioeconomic Gradients Within a Medically Underserved Appalachian Region.

Objectives: To assess type-specific prevalence of human papillomavirus (HPV) infection in a medically underserved Appalachian area and to determine whether gradients in poverty are associated with prevalence.

Methods: Among 398 women, a validated assay tested self-collected cervicovaginal samples for 37 HPV types. Three economic strata were created based on household income: below the federal poverty level for 1 person, between the FPLs for families of 1 to 4 persons, and above the FPL for a family of 4.

Polycyclic aromatic hydrocarbons (PAHs) in Mississippi seafood from areas affected by the Deepwater Horizon Oil Spill.

Seafood samples from the fishing ground closure areas of Mississippi Gulf Coast that were affected by the Deepwater Horizon Oil Spill Disaster were collected and analyzed for twenty-five 2- to 6-ring PAHs, about one month after the first day of incident. A total of 278 seafood samples consisting of 86 fishes, 65 shrimps, 59 crabs, and 68 oysters were collected and analyzed weekly from May 27, 2010 until October 2010 and monthly thereafter until August 2011. Statistically higher levels of total PAHs were detected in all four types of seafood samples during early part of the sampling period compared to the later months.

Effect of osmolality and selected ions on retraction of the distome body into the cercaria tail chamber of Proterometra macrostoma (Trematoda: Azygiidae).

The furcocystocercous cercariae of the digenetic trematode, Proterometra macrostoma , possess a tail chamber into which their distome body withdraws prior to emergence from their snail intermediate host. The process of distome retraction and the conditions that trigger it in this species are not clear. The objectives of the present study were (1) to describe the retraction process in P.
