Purpose: Adolescents and young adults (AYAs) with cancer often undergo aggressive end-of-life (EOL) care. We evaluated whether specialized palliative care (SPC) involvement is associated with the receipt of intensive EOL care among AYAs. Methods: This retrospective study included patients with cancer treated between the ages of 15 and 39 years at a university hospital, who died during 2009–2022. The primary outcome was high-intensity EOL (HI-EOL) care, which was defined as ≥1 session of intravenous chemotherapy <14 days from death or during the final 30 days of life, ≥1 hospitalization at an intensive care unit, >1 emergency room admission, or >1 hospitalization at an acute care unit during the final 30 days of life. We determined predictors of outcomes using multiple logistic regression models. Results: We analyzed 132 AYAs (75 with SPC involvement), of whom 42.4% (95% confidence interval [CI]: 33.9%–51.3%) underwent HI-EOL care. The prevalence of HI-EOL care was significantly lower in those who had SPC involvement than in those without SPC involvement (adjusted odds 0.30; 95% CI: 0.13–0.69; p = 0.005). Using no SPC involvement group as a reference, the adjusted odds for SPC involvement ≤60 days and >60 days were 0.71 (95% CI: 0.18–2.78; p = 0.63) and 0.22 (95% CI: 0.09–0.57; p = 0.002), respectively. Conclusion: In AYAs with cancer, SPC involvement and duration were associated with a lower incidence of HI-EOL care. Thus, integrating SPC into oncology may improve EOL care for AYAs.

Purpose. We aimed to investigate factors related to superior and inferior hemifield defects in primary open-angle glaucoma (POAG). Methods. Sixty-seven subjects with newly diagnosed, untreated POAG underwent optical coherence tomography (OCT) of the disc area, macular ganglion cell complex (mGCC), and circumpapillary retinal nerve fiber layer (cpRNFL) thickness within 6 months of the visual field (VF) test. Based on the VF and OCT results, 40 subjects had a superior and 27 an inferior hemifield defect. Clinical data including visual acuity, refractive error, disc hemorrhage, VF indexes, and medical history were recorded. Results. Average mGCC thickness corresponding to the defective hemifields was thinner in the superior VF defect group than in the inferior VF defect group (P=0.003). Average total deviation (TD) was comparable between the two groups. However, the superior VF defect group had a higher prevalence of defects (P=0.001) and lower TD (P=0.002) within central 5 degrees of VF than the inferior VF defect group. In multivariate regression analyses, the temporal-lower and inferior-temporal cpRNFL thicknesses were significant contributing factors to the inferior mGCC thickness in the superior VF defect group. In the inferior VF defect group, the disc area, family history of glaucoma, and temporal-upper cpRNFL thickness contributed to the superior mGCC thickness. Conclusion. The inferior mGCC thickness corresponding to the superior hemifield defect group was significantly thinner than the superior mGCC thickness corresponding to the inferior hemifield defect group. The factors related to the reduction of the corresponding mGCC thickness may differ between superior VF defect and inferior VF defect groups. [ABSTRACT FROM AUTHOR]

Purpose. To investigate factors related to a right-left difference in visual field defect in untreated normal tension glaucoma (NTG). Methods. The medical records of 92 patients with untreated NTG were reviewed. Ocular blood flow was evaluated with laser speckle flowgraphy, and the mean blur rate (MBR) at the optic nerve head was analyzed. Relationships between right-left differences in mean deviation (MD), intraocular pressure, MBR, spherical equivalent, central corneal thickness, and mean ocular perfusion pressure were evaluated using Spearman’s rank correlation coefficient. Multiple regression analysis was used to detect factors contributing to a right-left difference in MD. Results. The right-left difference in MD was correlated with differences in intraocular pressure (r=−0.263, P=0.011), MBR (r=0.417, P<0.001), and spherical equivalent (r=0.213, P=0.042), but not with central corneal thickness or mean ocular perfusion pressure. Multiple regression analysis showed that a difference in MBR was the only significant contributor to a right-left difference in MD (slope 0.047, 95% confidence interval 0.025–0.069; P<0.001). Conclusion. In untreated NTG, a difference in blood flow at the optic nerve head was a significant contributor to a right-left difference in visual field defect. [ABSTRACT FROM AUTHOR]

Purpose. To compare optical coherence tomography angiography (OCT-A) and laser speckle flowgraphy (LSFG) for the diagnosis of normal-tension glaucoma (NTG). Methods. Twenty-eight eyes of 28 patients with NTG and 25 eyes of 25 normal subjects matched for age, refractive errors, systemic blood pressure, and central corneal thickness were evaluated. OCT-A was used to measure whole image vessel density, inside disc vessel density, and peripapillary vessel density; using LSFG, mean blur rate (MBR) inside the whole optic nerve head (ONH) area (MBRA), and MBR of the vessel area (MBRV) and tissue area (MBRT) inside the ONH, were determined. Receiver operating characteristic (ROC) curves and areas under the ROC (AUROC) were used to assess the diagnostic ability of each variable. Results. The AUROC for OCT-A whole image vessel density (0.950) was significantly greater than that for OCT-A peripapillary vessel density (0.830) and for all LSFG parameters (MBRA = 0.793, MBRV = 0.601, and MBRT = 0.61) (P<0.001). The AUROC for OCT-A inside disc vessel density (0.931) was significantly greater than that for all LSFG parameters (P<0.005). Conclusions. OCT-A vessel density had a higher glaucoma diagnostic ability compared to all LSFG parameters in patients with NTG. [ABSTRACT FROM AUTHOR]

Purpose. To evaluate the relationships among the optic nerve head (ONH) area, macular ganglion cell complex (mGCC) thickness, circumpapillary retinal nerve fiber layer (cpRNFL) thickness, and visual field defects in patients with primary open angle glaucoma (POAG). Methods. This retrospective study included 90 eyes of 90 patients with POAG. The ONH area, rim area, mGCC thickness, and cpRNFL thickness were measured using optical coherence tomography. Mean deviation (MD) was measured using standard automated perimetry. The relationships among clinical factors including age, refraction, the ONH area, the rim area, the mGCC thickness, the cpRNFL thickness, and MD were evaluated using correlation coefficients and multiple regression analyses. Results. The significant correlation of the ONH area with refraction (r=0.362, P<0.001), the mGCC thickness (r=0.225, P=0.033), and the cpRNFL thickness (r=0.253, P=0.016) was found. Multiple regression analysis showed that the ONH area, rim area, and MD were selected as significant contributing factors to explain the mGCC thickness and cpRNFL thickness. No factor was selected to explain MD. Conclusions. The ONH area, in other words, the disc size itself may affect the mGCC thickness and cpRNFL thickness in POAG patients. [ABSTRACT FROM AUTHOR]

Purpose. To determine the clinical features, microbial profiles, treatment outcomes, and prognostic factors for endogenous bacterial endophthalmitis (EBE). Methods. The medical records of 27 eyes of 21 patients diagnosed with EBE for 11 years were reviewed. Collected data included age, site of infection, visual acuities (VAs), microbial profiles, and treatment regimen. Results. The mean age was 68.5 years. Gram-positive organisms accounted for 76.2%, while gram-negative ones accounted for 19.0%. Staphylococcus aureus was the most common causative organism (52.3%) of which 72.7% was methicillin-resistant S. aureus. A final VA of ≥20/40 was achieved in 44% and 20/200 or better was in 64%. Eyes with initial VA of ≥20/200 (P = 0.003) and focal involvements (P = 0.011) had significantly better final VA. Initial VA (P = 0.001) and the interval between onset of ocular symptoms and intravitreal antibiotic injection (P = 0.097) were associated with final VA in eyes receiving intravitreal antibiotics. Conclusions. EBE is generally associated with poor visual outcome; however the prognosis may depend on initial VA, extent of ocular involvement, and an interval between onset of ocular symptoms and intravitreal antibiotic injection. Early diagnosis and early intravitreal injection supplement to systemic antibiotics might lead to a relatively good visual outcome. [ABSTRACT FROM AUTHOR]
