Panophthalmitis is a severe condition involving not only the eye but also the surrounding orbital soft tissues. An endogenous source of panophthalmitis is rare and requires a thorough investigation to identify the infection's origin, which can be challenging. We present a rare case of a 65-year-old male patient with no systemic symptoms who presented to the emergency room with left-eye panophthalmitis, ultimately revealing occult colorectal cancer.

Article Synopsis
  • The study aimed to investigate the relationship between phase angle (PhA), a marker of hydration and nutritional status, and the development of sarcopenia in older adults.
  • It involved 696 participants aged 75 and older, assessing them for sarcopenia and related physical capabilities over 24 months using various tests and methods.
  • While lower baseline PhA was observed in those who developed sarcopenia, it was not confirmed as a significant predictor after accounting for other related factors, raising questions about its practical use as an early marker for sarcopenia risk.

This study aimed to analyze the evolution of visual changes in cognitively healthy individuals at risk for Alzheimer's disease (AD). Participants with a first-degree family history of AD (FH+) and carrying the Ε4+ allele for the ApoE gene (ApoE ε4+) underwent retinal thickness analysis using optical coherence tomography (OCT) and visual function assessments, including visual acuity (VA), contrast sensitivity (CS), color perception, perception digital tests, and visual field analysis. Structural analysis divided participants into FH+ ApoE ε4+ and FH- ApoE ε4- groups, while functional analysis further categorized them by age (40-60 years and over 60 years).

Introduction: Alzheimer's disease (AD) is the most common form of dementia affecting the central nervous system, and alteration of several visual structures has been reported. Structural retinal changes are usually accompanied by changes in visual function in this disease. The aim of this study was to analyse the differences in visual function at different stages of the pathology (family history group (FH+), mild cognitive impairment (MCI), mild AD and moderate AD) in comparison with a control group of subjects with no cognitive decline and no family history of AD.

A longitudinal alteration in health-related quality of life (HRQoL) over a two-year period and its association with early-stage chronic kidney disease (CKD) progression was investigated among 1748 older adults (>75 years). HRQoL was measured by the Euro-Quality of Life Visual Analog Scale (EQ-VAS) at baseline and at one and two years after recruitment. A full comprehensive geriatric assessment was performed, including sociodemographic and clinical characteristics, the Geriatric Depression Scale-Short Form (GDS-SF), Short Physical Performance Battery (SPPB), and estimated glomerular filtration rate (eGFR).

The prescription of daily contact lenses does not often include a full astigmatic correction. We question here whether this full astigmatic correction (for low to moderate astigmatism) provides a substantial improvement in the overall visual performance compared to a more conservative approach based only on the prescription of spherical contact lenses. The visual performance of 56 contact lens neophytes divided in two contact lens fitting groups (toric versus spherical lens fit) was assessed using standard visual acuity and contrast sensitivity tests.

Cerebrovascular disease is responsible for up to 20% of cases of dementia worldwide, but also it is a major comorbid contributor to the progression of other neurodegenerative diseases, like Alzheimer's disease. White matter hyperintensities (WMH) are the most prevalent imaging marker in cerebrovascular disease. The presence and progression of WMH in the brain have been associated with general cognitive impairment and the risk to develop all types of dementia.

Article Synopsis
  • The early signs of Alzheimer's disease (AD) can manifest as changes in the eye and brain function long before clinical symptoms appear, suggesting potential early biomarkers for the disease.
  • Healthy individuals with a family history of AD show differences in visual acuity, contrast sensitivity, and retinal structure, which may relate to changes in brain activity measured through electrophysiological tests.
  • High-risk subjects exhibited a relationship between improved visual acuity and certain brain activity patterns, indicating potential connections between ophthalmological changes and visual processing in the context of Alzheimer's risk.

Pixuna virus (PIXV) and Río Negro virus (RNV) are mosquito-borne alphaviruses belonging to the Venezuelan Equine Encephalitis (VEE) complex, which includes pathogenic epizootic and enzootic subtypes responsible for life-threatening diseases in equines. Considering that the first steps in viral infection are crucial for the efficient production of new progeny, the aim of this study was to elucidate the early events of the replication cycle of these two viruses. To this end, we used chemical inhibitors and the expression of dominant-negative constructs to study the dependence of clathrin and endosomal pH on PIXV and RNV internalization mechanisms.
