The cost of publishing in an indexed ophthalmology journal in 2019.

OBJECTIVE: To determine the proportion of indexed ophthalmology journals with article processing charges (APCs) and potential factors associated with APCs. DESIGN: Cross-sectional study. PARTICIPANTS: Web of Science-indexed Ophthalmology journals in 2019. METHODS: Indexed ophthalmology journal web sites were reviewed to obtain information on APCs, impact factor (IF), publication mode, publisher type, journal affiliation, waiver discount, and continent of origin. For data unavailable on the web site, the journal was contacted. Journal publication mode was categorized into subscription, fully open access, and hybrid (open access and subscription combined). Linear regression analysis was used to evaluate the association between APCs and the above variables. MAIN OUTCOME MEASURE: Proportion of ophthalmology journals with APCs. RESULTS: 59 indexed ophthalmology journals were identified; 3 (5.1%) subscription only, 10 (16.9%) open access, and 46 (78.0%) hybrid. Overall 52/59 (88.1%) journals had APCs; 10 of 59 journals (16.9%) required APCs for publication (7 fully open access and 3 hybrid journals), whereas 42/59 (71.2%, all hybrid journals) had optional APCs for open access. The 7/59 journals (11.9%) without APCs included 100% (3/3) of the subscription-only journals, 30% (3/10) of the open access, and 2% (1/46) of the hybrid journals. The mean cost for journals with APCs was US$2854 ± 708.9 (range US$490-5000). Higher IF, publication mode, and commercial publishers were associated with higher APCs. CONCLUSIONS: 16.9% of indexed ophthalmology journals in 2019 required APCs, and additional 71.2% hybrid journals had APCs for the option of open access. Independent predictors of APCs were IF and publication mode.

The current state of retinopathy of prematurity in India, Kenya, Mexico, Nigeria, Philippines, Romania, Thailand, and Venezuela.

Retinopathy of prematurity (ROP) is one of the leading causes of preventable blindness in children worldwide. Middle-income nations are currently experiencing epidemic levels of ROP, because greater access to neonatal intensive care units has improved survival rates of premature infants, but without sophisticated oxygen regulation. The epidemiology, screening infrastructure, treatment options, and challenges that these countries face are often tied to unique local socioeconomic, cultural, geopolitical, and medical factors. We present an overview and narratives of the current state of ROP in eight countries that are or soon will be experiencing ROP epidemics-India, Kenya, Mexico, Nigeria, Phillipines, Romania, Thailand, and Venezuela-with a view to fostering both an understanding of the differences in the ROP landscape in various settings and an interest in the further development of ROP screening and treatment services tailored to local requirements.

Morphology and location of surface landmarks of foramen ovale in Kenyans / Morfología y ubicación de puntos anatómicos de superficie del foramen oval en kenianos

Foramen ovale is a surgically important aperture of the skull since it allows approach to and manipulation of the trigeminal ganglion as it lies in the Meckel's cave. This transfacial approach, Hartel's approach, requires two anatomical points for accurate cannulation; the zygomatic point and the pupil point. This study describes the morphology and location of foramen ovale and describes the pupil point in relation to the medial canthus in the Kenyan population. Department of Human Anatomy departmental review board approved the study. Two hundred dry skulls from the Department of Human Anatomy were studied using a digital calliper with help of a measuring frame. The results were analysed using SPSS version 20. The results showed the length and width of right foramen ovale was 7.69 mm mean (SD ±1.31) and 4.24 mm (±0.64) respectively while the left foramen ovale was 7.68 mm (±1.23) and 4.28 mm (±0.74). The distance of the zygomatic point from the external auditory meatus on the right was 23.54 mm (±2.26) and the left was 23.49 mm (±2.16). The median distances of the pupil point in relation to the medial canthus was 9.5mm on the right and 8.1 mm on the left. These results were significantly different from other population data. Neuronavigational aids to foramen ovale in Kenyans should take this into consideration.

El foramen oval es una abertura quirúrgicamente importante del cráneo, que permite el enfoque y manipulación del ganglio trigeminal ya que se encuentra en la impresión trigeminal (fosita de Meckel). Este enfoque transfacial, el enfoque de Hartel, requiere dos puntos anatómicos para la canalización precisa; el punto cigomático y el punto de la pupila. Este estudio describe la morfología y la ubicación del foramen oval, y el punto pupilar en relación al canto medial en la población de Kenia. La junta directiva del Departamento de Anatomía Humana aprobó el estudio. Doscientos cráneos secos procedentes del Departamento de Anatomía Humana se estudiaron utilizando un caliper digital con ayuda de un marco de medición. Los resultados fueron analizados mediante el programa SPSS versión 20. Los resultados mostraron que la longitud y ancho del foramen oval derecho fue de 7,69 mm media (±1,31) y 4,24 mm (±0,64), respectivamente, mientras que el foramen oval izquierdoo fue de 7,68 mm (±1,23) y 4,28 mm (±0,74). La distancia del punto cigomático desde el meato acústico externo derecho fue 23,54 mm (±2,26) y el izquierdo de 23,49 mm (±2,16). Las distancias promedios del punto de la pupila en relación con el canto medial fueron de 9,5 mm (el derecha) y 8,1 mm (el izquierdo). Estos resultados fueron significativamente diferentes de otros datos demográficos. El apoyo para la neuronavegación para acceder al foramen oval en kenianos debe tener esto en consideración.
