    Abstract ABSTRACTThe spatial structure of local uncertainty of shallow-water satellite-derived bathymetry (SDB) relative to model type, imagery, and geographical adaptability was examined for an area near Key West, Florida (United States). The model types examined were a commonly used quasi-empirical linear regression model and a decision tree-based Categorical Boosting (CatBoost) machine learning (ML) model. Image types examined were (four) cloud-free Sentinel-2 images and a maximum blue band (Band 2) value image composite of the four Sentinel-2 images. Initial models fitted were based on band reflectances alone. Geographical adaptivity was added by including UTM coordinates and refitting the models. Major findings were: 1) The ML/CatBoost models provided substantially better depth estimates than the quasi-empirical models. 2) The geographically adaptive models outperformed the non-geographically adaptive models. 3) The ML/CatBoost models that included non-visible spectral bands including infra-red improved SDB accuracy compared to ML/CatBoost and quasi-empirical models based only on visible spectral bands. 4) Accuracies from ML/CatBoost models were comparable across all individual images and the composite suggesting that CatBoost models eliminate or at least minimize the need to find “the best” cloud-free image nor is it necessary to create a composite image. 5) Localized SDB inaccuracy was spatially random. 6) Significant spatial hotspots where SDB accuracy was consistently higher or lower across all images and models were present. Results suggest that image selection is less important for global and local SDB accuracy than using ML models that detect hidden interactions and non-linear relationships among pixel reflectance and geographic location. The spatially random local deviation from global accuracy suggests a weak ability to infer local accuracy from neighboring accuracies. This lack of spatial autocorrelation among errors is potentially problematic for the use of SDB maps for navigation since error at any ...

    Abstract Purpose: Dense vitreous hemorrhage is a vision-threatening disease with varied clinical manifestations. Herein, we aimed to evaluate its causes and outcomes in patients without diabetes.
    Methods: A retrospective cohort including 60 eyes from 60 patients with an initial diagnosis of non-traumatic fundus-obscuring dense vitreous hemorrhages and without diabetes was recruited. The relevant medical records from January 2013 to December 2019 were reviewed and analyzed. We classified patients into the following four groups, depending on the underlying cause of dense vitreous hemorrhage: eight cases in the age-related macular degeneration (AMD) group, four cases in the posterior vitreous detachment group, 20 cases in the Tear group, and 28 cases in the Vascular group.
    Results: The most common cause of dense vitreous hemorrhage was retinal vascular obstructive disease (46.7%); the AMD group showed the worst prognosis. The extent of best corrected visual acuity change was significantly better in patients who underwent vitrectomy compared to those receiving conservative treatment; best corrected visual acuity change (logMAR) was 1.62±0.57 and 1.06±0.88 in the surgical and non-surgical groups, respectively (p=0.007, Student t-test).
    Conclusions: Retinal vascular disease is the most common cause of vitreous hemorrhages, and surgical treatments have a better visual outcome than non-surgical treatments.

    Abstract (1) Background: We aim to find a novel blink parameter in nasolacrimal duct obstruction (NDO) patients and analyze parameters that could reflect subjective symptoms and objective indicators at the same time through a blink dynamic analysis. (2) Methods A retrospective study was conducted with 34 patients (48 eyes) who underwent lacrimal passage intubation (LPI) and 24 control groups (48 eyes). All patients’ blink patterns were measured using an ocular surface interferometer before and after LPI, including total blink (TB) and partial blink (PB) and the blink indices blink time (BT), lid closing time (LCT), closure time (CT), lid opening time (LOT), interblink time (IBT), closing speed (CS) and opening speed (OS). The tear meniscus height (TMH) was measured, and the questionnaire “Epiphora Patient’s Quality of Life (E-QOL),” which includes daily activity restriction as well as static and dynamic activities, was completed. (3) Results: Compared to CT and the ratio of CT during BT (CT/BT) in control (89.4 ± 20.0 msec, 13.16%), those in NDOs were longer (140.3 ± 92.0 msec, 20.20%) and were also related to TMH. After LPI, CT and CT/BT were recovered to 85.4 ± 22.07 msec, 13.29% ( p < 0.001). CT and CT/BT showed a positive correlation with the E-QOL questionnaire score, particularly with dynamic activities. (4) Conclusions: CT and CT/BT, which are objective indicators associated with subjective symptoms of patients, are considered new blink indices for the evaluation of NDO patients with Munk’s score.

    Abstract Colorectal cancer (CRC) is a type of cancer that develops in the colon or rectum and is the second leading cause of cancer-related death worldwide. Several epidemiology studies have identified a significant sexual dimorphism in CRC, with women exhibiting a lower incidence rate and delayed onset compared to men. This study aims to investigate the sexual dimorphism in the inflammatory response in colitis-associated CRC and its relationship with estrogen and estrogen receptors. An azoxymethane (AOM)/dextran sodium sulfate (DSS) mouse model was used to induce colitis-associated CRC. Five-week-old male and female mice were randomly assigned into either the control group or the AOM/DSS CRC group, with 10 mice in each group. Colitis-associated CRC was induced by injecting AOM (10 mg/kg) and administering two-cycles of DSS treatment in the drinking water. The results revealed a significant decrease in colon length exclusively in the female group, indicating more severe colonic inflammation (
