PRECIS Corvis ST Tonometry and Ocular Response Analyzer measurements were conducted in primary open-angle glaucoma and normative subjects. Many parameters were significantly correlated, however, the strengths were weak to moderate. PURPOSE Reichert Ocular Response Analyzer (ORA) parameters are derived from pressure information following the application of air-jet, whereas detailed structural observation can be made using the Corneal Visualization Scheimpflug Technology instrument (CST). The purpose of the study was to investigate the association between CST measurements and ORA measured corneal hysteresis (CH). METHODS 104 eyes of 104 patients with primary open-angle glaucoma and 35 eyes from normative subjects. Measurements of CST, ORA, axial length (AL), average corneal curvature (CC), central corneal thickness (CCT) and intraocular pressure (IOP) with Goldmann applanation tonometry (GAT) were carried out. The association between CST and ORA parameters was assessed using linear regression analysis, with model selection based on the second order bias corrected Akaike Information Criterion index. RESULTS DA ratio (corneal softness, R=-0.51), SP A1 (corneal stiffness, R=0.41), and Inverse Radius (integrated area under the curve of the inverse concave radius, R=-0.44) were significantly correlated with CH (P less then 0.05). The optimal model to explain CH using CST measurements was given by CH=-76.3 + 4.6*A1 time (applanation time in the corneal inward movement) + 1.9*A2 time (second applanation time in the corneal outward movement) + 3.1 * highest concavity deformation amplitude (magnitude of movement of the corneal apex from before deformation to its highest concavity) + 0.016*CCT (R=0.67, P less then 0.001). CONCLUSION CST parameters are significant, but weakly or moderately, related to ORA measured CH.PRéCIS This study found an association between thinner superotemporal retinal nerve fiber layer and obstructive sleep apnoea. However, the lack of association of sleep apnoea with other disc measures does not support a link with glaucoma. AIM Previous findings on the link between obstructive sleep apnoea (OSA) and increased glaucoma risk have been inconsistent. In a community-based study of middle-aged and older adults, we explored for differences in optic disc measures that may resemble preclinical glaucomatous changes in relation to OSA status and severity. METHODS A total of 865 participants (46-67▒y; 45% male) underwent an at-home sleep study during which their apnoea-hypopnoea index (AHI) and sleep oxygen saturation level were measured. Participants were determined to have no OSA (AHI30). At a six-year follow-up visit, the optic discs of both eyes were imaged using spectral domain optic coherence tomography to measure the Bruch's membrane opening minimum rim widths (BMO-MRW) and retinal nerve fiber layer (RNFL) thicknesses. RESULTS Based on the AHI, 411 participants (48%) had OSA, of whom 92 (11% of total sample) and 26 (3%) had moderate and severe OSA, respectively. In the multivariate analysis, participants with severe OSA had thinner RNFL superotemporally than those without OSA or with mild OSA. (P less then 0.001 and P=0.001, respectively). Additionally, superotemporal RNFL was inversely associated with AHI (P=0.004) and sleep time with oxygen saturation level less then 90% (P=0.005). There was no association between OSA measures and BMO-MRW. CONCLUSIONS Our findings do not provide strong evidence of a link between measures of OSA and the optic disc. However, the association between increased OSA severity and thinner superotemporal RNFL has been reported consistently in previous studies and thus warrants further evaluation.We linked the Medicare Provider Utilization and Payment Data for Home Health and the Home Health Compare data for the year 2016 to identify home healthcare agency (HHA) characteristics associated with acute care hospitalization (ACH) or emergency department (ED) use. The study cohort consisted of 9,800 HHAs. Beta regression was used to examine the association between average age, race/ethnic composition, number of skilled nursing visits, number of therapy visits, percentage of dual eligible patients, HHA ownership, HHA location, Medicare tenure, proportion of patients with a diagnosis of schizophrenia, stroke, diabetes, depression, chronic obstructive pulmonary disease (COPD), heart failure, cancer and Alzheimer disease, and ACH or ED use. After controlling for HHA-level characteristics, variations in HHAs' ACH and unplanned ED visits were found. For-profit HHAs were significantly less likely to have patients with ACH. (Odds ratio = -0.05, p = 0.020), HHAs in the Midwest, South, and West had lower odds of ACH. HHAs that serve more than 50% Black patients had significantly decreased odds (β = -0.16, p less then 0.001) of ACH. A 1-unit increase in the proportion of patients with a diagnosis of schizophrenia, COPD, stroke, heart failure, and Alzheimer disease was associated with increased odds of hospitalization. For each unit increase in the number of skilled nursing visits, the odds of ACH increased by 0.02 (p = 0.001). β-Glycerophosphate For-profit and nonprofit HHAs had a significant decrease in the odds of unplanned ED visits (p less then 0.05). An increase in the proportion of patients with COPD was associated with increased odds of unplanned ED visits (p less then 0.001). HHA characteristics are associated with hospitalization and ED use without hospitalization. These characteristics point to variation in quality of care measured by ACH and ED use.The purpose of this study was to describe self-reported outcomes and perceptions of community-dwelling older adults who participated in a 6-month prevention-focused home care physical therapy program entitled Home-based Older Persons Upstreaming Prevention Physical Therapy (HOP-UP-PT). A 17-question telephone survey was offered 1 to 3 months after program completion to HOP-UP-PT participants who completed a minimum of three visits. Self-reported fall outcomes, healthcare utilization outcomes, perceptions of interventions, and financial perceptions were descriptively analyzed. There were 18 survey respondents (9 male, 9 female, mean age = 79 years). No falls were reported by 15 respondents and 3 reported 1 to 2 falls without injury. Seventeen participants reported no hospitalizations, one reported only overnight emergency room observation, and no participants reported requiring physical therapy. Participants reported benefits of activity trackers (18/18), fall-prevention exercises (17/18), and electronic blood pressure monitor use (13/18).
