The consequences of using 25% whole or shelled sea urchin as an ingredient in anchovy sauce on its fermentation and development of its physicochemical properties after 20 days fermentation was studied. Two varieties of fish and sea urchin sauce were made with or without shell at 1:2:1 ratio (salt:fish:sea urchin) plus a control fish sauce at 1:3 ratio (salt:fish). All sauces were fermented at 40-50 °C for 20 days, where for the first 7 days the preparation remained in a static phase.

Prcis: Participant surveys taken after using tablet-based and smart visual function analyzer (SVFA) perimetry tests suggest that patients may prefer novel perimetry tests over traditional visual field machines.

Purpose: Compare patient experience using the IMOvifa SVFA and the tablet-based Melbourne Rapid Fields visual field (VF) tests to the Humphrey Field 24-2 Swedish Interactive Threshold Algorithm Standard.

Patients And Methods: Prospective observational cohort study on adult participants with diagnoses of glaucoma suspect, ocular hypertension, or glaucoma.

Purpose: The tablet-based Melbourne Rapid Fields (MRF) visual field (VF) test and the IMOvifa Smart Visual Function Analyzer (SVFA) are portable perimeters that may allow for at-home monitoring and more frequent testing. We compared tablet and SVFA results with outputs from the Humphrey Field Analyzer (HFA) 24-2 Swedish Interactive Threshold Algorithm Standard program.

Significance: Corneal haze remains a frequent post-operative finding in patients undergoing corneal cross-linking. It has been shown that autologous serum tears promote epithelial healing and reduce post-operative pain; however, the role in the prevention of corneal haze has not been reported.

Purpose: This study aimed to compare the effect of autologous serum tears versus preservative-free artificial tears on the prevention and resolution of post-cross-linking corneal haze.

Article Synopsis
  • The study aimed to estimate the incidence of corneal endothelial transplantation (CET) and identify risk factors in patients with noninfectious ocular inflammation using data from a cohort study of adult patients in the U.S.
  • A total of 14,264 eyes were analyzed, revealing a 10-year incidence rate of 1.10% for CET, with notable risk factors including older age (over 60), specific types of inflammation (anterior uveitis and scleritis), and prior operations like cataract and tube shunt surgery.
  • The findings suggest that while CET is rare among these patients, certain conditions like hypotony and band keratopathy significantly increase the likelihood of requiring the procedure.

Background/aims: The COVID-19 pandemic has been associated with a decline in emergency department (ED) presentations for trauma. The purpose of this study is to compare the estimated number and characteristics of eye injuries in 2020, the year of the COVID-19 pandemic, to those in 2011-2019.

Methods: A stratified probability sample of US ED-treated eye injuries was used to calculate the estimated annual number and incidence of these injuries in 2020, the year of the pandemic, and 2011-2019 (prepandemic years).

The aim of this study was to evaluate the influence of vinification techniques on volatile compounds and sensory profiles in young Palomino fino white wines. Four winemaking techniques (pellicular maceration, supra-extraction and use of commercial yeast strains and of β-glycosidase enzymes) were implemented to enhance the aromatic quality of wines elaborated from this neutral variety of grape. Volatile compound content, aromatic profile (OAVs) and sensorial analysis were determined.

In Europe, the consumption of seaweeds and derived products has increased in recent years, due to the expansion of Asian cuisine and the emergence of many top-level chefs. Often in collaboration with scientists, many have initiated a new gastronomy using algae. However, little is known about the quality and degree of freshness of seaweeds for direct consumption or fresh use.

Introduction: The COVID-19 pandemic has presented challenges to managing vascular risk factors with in-person follow-up of patients with asymptomatic carotid stenosis enrolled in the CREST2 trial. CREST2 is comparing intensive medical management alone versus intensive medical management plus revascularization with endarterectomy or stenting. We performed a study to evaluate the feasibility of a home-based program for testing blood pressure (BP) and low-density lipoprotein (LDL) in CREST2.

Background And Purpose: The CREST2 trial (Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis) is comparing intensive medical management (IMM) alone to IMM plus revascularization with carotid endarterectomy or transfemoral carotid artery stenting for preventing stroke or death within 44 days after randomization or ipsilateral ischemic stroke thereafter. There are extensive clinical trial data on outcomes after revascularization of asymptomatic carotid stenosis, but not for IMM. As such, the experimental treatment in CREST2 is IMM, which is described in this article.

Background: The effect of different cooking methods (boiling, vacuum and steamed cooking) on the volatile compound content and sensory properties of sea lettuce (Ulva rigida) seaweed was assessed. Sea lettuce was cooked at three different temperatures (50, 70 and 100 °C) for three different lengths of time (5, 10 and 15 min). Various statistical techniques were employed in order to establish any possible changes.

Background: Edible seaweeds are one of the most important resources that currently exist for their multiple uses and applications. Like other food types, during their storage there are significant changes in sensory characteristics associated with loss of freshness and with production and/or degradation of their volatile compounds. In this study, multiple headspace sorptive extraction (MHSSE) coupled with gas chromatography/mass spectrometry (GC/MS) detection has been applied to an edible green seaweed (Ulva rigida) in order to determine the evolution of volatile compounds during storage for 12 days at 4 or 16 °C.

The aim of this study was to characterize the biochemical changes and microbiological processes involved in the sensory deviation of "sobretablas" wines during biological aging, which leads to the origin of special or rare "palo cortado" wines. Industrial trials of biological aging of "sobretablas" wines with the potential for the development of lactic acid bacteria (LAB) were performed to study this phenomenon. The results showed that sensory deviation was due to the development of malolactic fermentation (MLF) together with an attenuated aerobic metabolism of "flor" yeast.

Background And Purpose: Inflammatory biomarkers predict incident and recurrent cardiac events, but their relationship to stroke prognosis is uncertain. We hypothesized that high-sensitivity C-reactive protein (hsCRP) predicts recurrent ischemic stroke after recent lacunar stroke.

Methods: Levels of Inflammatory Markers in the Treatment of Stroke (LIMITS) was an international, multicenter, prospective ancillary biomarker study nested within Secondary Prevention of Small Subcortical Strokes (SPS3), a phase III trial in patients with recent lacunar stroke.
