Background: Patient navigation is an evidence-based intervention for reducing delays in cancer care for underserved populations. There are limited economic evaluations of patient navigation in the US health care system and few have considered costs at various phases along the implementation spectrum. Having economic data, including costs and cost savings, can support sustainability of patient navigation programs.

Type 3 macular neovascularization (MNV) is a unique form of neovascular age-related macular degeneration (AMD) that presents distinct pathogenetic features, clinical manifestations, and prognostic considerations when compared to types 1 and 2 MNV. Insights gained from clinicopathological correlations, bridging in vivo examination techniques with ex vivo histological analysis, have significantly enhanced our comprehension of this MNV phenotype, shaped current management strategies and influenced future directions for therapeutics. The particularities of type 3 MNV, which may largely stem from its origin from the retinal vasculature, are critically important for predicting the disease course.

Article Synopsis
  • Some doctors and medical staff need to start asking patients about their sexual orientation and gender identity (SOGI) to give better care, but not everyone is onboard yet.
  • Researchers talked to 20 staff members at a healthcare center to find out how they feel about collecting this kind of information and what problems they see.
  • They found that people are worried about how patients will react, and there are differences in thinking between clinical staff (who work directly with patients) and nonclinical staff (who have different roles), so more education is needed to help everyone understand why gathering this information is important.

Article Synopsis
  • - Abetalipoproteinemia (ABL) is a rare genetic disorder characterized by the absence of certain lipoproteins due to a defective triglyceride transfer protein, impacting the retina and leading to vision problems, including conditions resembling retinitis pigmentosa.
  • - Multimodal retinal imaging was conducted on two ABL patients, revealing significant eye changes like choroidal neovascularization and deposits in the retina, alongside a range of vision loss.
  • - The study suggests that mutations in the MTTP gene within the retina may contribute to ABL-related eye diseases, highlighting the importance of ongoing eye care for affected individuals, particularly to manage treatable conditions like choroidal neovascularization.

Purpose: To describe a new retinal phenotype characterized by bilateral, multifocal, subretinal vitelliform lesions along the vascular arcades that we refer to as multifocal vitelliform paravascular retinopathy (MVPR).

Design: Observational case series.

Methods: Multimodal retinal imaging including color fundus photography, fundus autofluorescence and cross sectional and en-face optical coherence tomography was performed to evaluate and characterize the lesions of MVPR.

Article Synopsis
  • The study investigated neovascularization (NV) in patients with angioid streaks (AS) due to pseudoxanthoma elasticum (PXE), aiming to explore its characteristics and outcomes while also proposing a classification system based on various imaging techniques.
  • It analyzed data from 85 patients, noting that 76% had type 1 NV, primarily around the optic disc, with many cases remaining nonexudative over five years, yet some progressed to more severe forms, increasing the risk of vision loss.
  • The research concluded that type 1 NV is common and can lead to significant visual impairment, while a newly developed classification system for AS ranges from non-NV stages to those with advanced NV

The pachychoroid disease spectrum is a phenotype characterized by alterations in choroidal vasculature which result in outer retinal and choriocapillaris damage and visual loss. The presence of pachyvessels is one of the key features of the pachychoroid phenotype. Recent imaging studies suggest that pachyvessels may form because of choroidal venous congestion in one or more quadrants.

Background: High mammographic density is one of the strongest breast cancer risk factors; however, determinants of high mammographic density are understudied in Black women. We assessed growth and development factors across the lifecourse in relation to mammographic density.

Methods: Within the Black Women's Health Study, we used Cumulus software to assess percent mammographic density from digital screening mammograms for 5,905 women ages 40 to 74 years.

Purpose: To report eight cases of acute posterior multifocal placoid pigment epitheliopathy (APMPPE) or persistent placoid maculopathy (PPM) initially masquerading as age-related macular degeneration in elderly individuals.

Methods: APMPPE or PPM eyes in patients above age 55 years with macular retinal pigment epithelium disruption including drusenoid lesions on macular examination and/or with multimodal imaging were included. At least one method of multimodal imaging including fluorescein angiography (FA), indocyanine green angiography, optical coherence tomography (OCT), and OCT angiography (OCTA) was performed in all eyes for diagnosis and to monitor for macular neovascularization.

Background: Social needs inhibit receipt of timely medical care. Social needs screening is a vital part of comprehensive cancer care, and patient navigators are well-positioned to screen for and address social needs. This mixed methods project describes social needs screening implementation in a prospective pragmatic patient navigation intervention trial for minoritized women newly diagnosed with breast cancer.

Purpose: Enface OCT may disclose a distinct "fingerprint-like' pattern within the HFL in various macular disorders. This study aims to investigate the frequency and characteristics of this pattern in healthy eyes and identify potential factors influencing its visibility.

Methods: Two, independent masked reading center graders evaluated for the presence and prominence of a fingerprint pattern in the Henle fiber layer (HFL) on enface OCT images from 33 healthy subjects (66 eyes).

Background: Research on racial and ethnic disparities in costs of care during the course of dementia is sparse. We analyzed Medicare expenditures for beneficiaries with dementia to identify when during the course of care costs are the highest and whether they differ by race and ethnicity.

Methods: We analyzed data from the 2000-2016 Health and Retirement Study (HRS) linked with corresponding Medicare claims to estimate total Medicare expenditures for four phases: (1) the year before a dementia diagnosis, (2) the first year following a dementia diagnosis, (3) ongoing care for dementia after the first year, and (4) the last year of life.

Article Synopsis
  • The study aimed to assess how a new social risk screening and referral system affected a community hospital's pediatric unit after its implementation in April 2022.
  • Data was collected from patients aged 0 to 17 during a year before and after the program's launch, analyzing changes in identifying social risks and consulting with social work.
  • Results showed a significant increase in the identification of social risks, more frequent and quicker social work consultations, and improved communication about these risks in discharge summaries after the implementation.

Central serous chorioretinopathy (CSC) is a relatively common disease that causes vision loss due to macular subretinal fluid leakage and it is often associated with reduced vision-related quality of life. In CSC, the leakage of subretinal fluid through defects in the retinal pigment epithelial layer's outer blood-retina barrier appears to occur secondary to choroidal abnormalities and dysfunction. The treatment of CSC is currently the subject of controversy, although recent data obtained from several large randomized controlled trials provide a wealth of new information that can be used to establish a treatment algorithm.
