Prosthetic Visual Acuity with the PRIMA System in Patients with Atrophic Age-related Macular Degeneration at 4 years follow-up.

Objective: To assess the efficacy and safety of the PRIMA subretinal neurostimulation system 48-months post-implantation for improving visual acuity (VA) in patients with geographic atrophy (GA) due to age-related macular degeneration (AMD) at 48-months post-implantation.

Design: First-in-human clinical trial of the PRIMA subretinal prosthesis in patients with atrophic AMD, measuring best-corrected ETDRS VA (Clinicaltrials.gov NCT03333954).

Parental Health Literacy, Empowerment, and Advocacy for Food Allergy Safety in Schools: A Cross-Sectional Study.

Background: Approximately 8% of elementary school-aged children in the United States have food allergies, a complicated health management situation that requires parents to use many types of health literacy, empowerment, and advocacy skills to work with school staff to protect their children.

Objective: This cross-sectional study examined (a) whether the highest versus lowest levels of functional, communicative, and critical health literacy are associated with higher perceived effectiveness of parental advocacy behaviors for safe food allergy management in schools [parental advocacy]; and (b) whether communicative and critical health literacy are more strongly associated with parental advocacy than functional health literacy.

Methods: A sample of parents of elementary school-aged children was recruited through 26 food allergy organizations and a research patient registry.

Effects of Extraction Methods on Phenolic Content in the Young Bamboo Culm Extracts of Munro.

Nowadays, many studies focus on the potential of bamboo as a source of bioactive compounds and natural antioxidants for nutraceutical, pharmaceutical, and food sources. This study is a pioneering effort to determine the total phenolic content, total flavonoid content and free radical scavenging activity, as well as the phenolic identification and quantification of . The study was conducted by using ethanol, methanol, and water for solvent extraction by applying cold maceration, Soxhlet, and ultrasonic-assisted extraction techniques.

Frequency of Urgent or Emergent Vitreoretinal Surgical Procedures in the United States During the COVID-19 Pandemic.

Importance: The American Academy of Ophthalmology (AAO) indicated that urgent or emergent vitreoretinal surgical procedures should continue during the coronavirus disease 2019 (COVID-19) pandemic. Although decreases in the frequency of critical procedures have been reported outside the field of ophthalmology, analyses are limited by volume, geography, and time.

Objective: To evaluate whether the frequency of ophthalmic surgical procedures deemed urgent or emergent by the AAO changed across the United States during the COVID-19 pandemic.

International service learning enhances nurse practitioner students' practice and cultural humility.

Academic and health care institutions are charged with improving quality-of-care outcomes by creating culturally educated health care professionals to practice in a global health care environment. International short-term service learning experiences provide nurse practitioner students an opportunity to meet clinical competency skills aligned with course curricula. Faculty can directly observe students' clinical practice, and students broaden diagnostic reasoning skills while earning credit for clinical hours.
