Objectives: The prevalence of obstructive sleep apnea (OSA) escalates with advancing age. Although the apnea-hypopnea index (AHI) is the standard measure for assessing OSA severity, it does not account for additional oximetric parameters that may influence disease progression in older adults. This study aimed to evaluate disparities in respiratory polygraphy/polysomnography parameters among patients with OSA, stratified by age and sex., Design: Retrospective propensity score-matched study., Setting and Participants: Sleep unit of a university hospital; 11,747 participants, 210 aged 80 years or older., Methods: Propensity score matching was used to establish 4 age cohorts, with the 210 oldest adults serving as the reference group. Primary outcome variables included the total sleep time with oxygen saturation (SaO 2 ) below 90% (T90), average SaO 2 , minimum SaO 2 , and AHI. The association between T90 and AHI, as well as the severity of OSA, was assessed across the 4 age categories., Results: Despite comparable AHI scores, the oldest patients with OSA exhibited the highest T90 and the lowest SaO 2 levels compared to younger counterparts. The proportion of patients with severe OSA and T90 in the highest quartile increased with age: 12.5% in young adults, 14.8% in adults, 21.7% in the old, and 34% in the very old participants (P < .001). old and very old patients had a greater likelihood of being in the most severe OSA category compared to the younger ones, with odds ratios (OR) 2.57 (95% CI 1.42-4.65) and 5.52 (95% CI 3.06-9.97), respectively. These patterns were more pronounced in women of advanced age, indicating a sex-specific variation in disease severity with increasing age., Conclusions and Implications: Old patients with OSA, particularly women, demonstrate elevated T90 and reduced SaO 2 levels, irrespective of AHI, indicating a hypoxemia increased risk. The diagnostic criteria, management, and outcomes for OSA may require adaptations to address the unique needs of very old populations., Competing Interests: Disclosures The authors declare no conflicts of interest., (Copyright © 2024 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Purpose: The aim of this study was to assess the short-term and long-term effectiveness of toric intraocular lenses (IOLs) as a treatment for significant postkeratoplasty astigmatism., Methods: This was a retrospective case review study that analyzes postkeratoplasty eyes after phacoemulsification with toric IOL implantation., Results: Seventy-five eyes were included. Previous surgery was penetrating keratoplasty (50.6%), deep anterior lamellar keratoplasty (34.6%), or automated anterior lamellar therapeutic keratoplasty (14.6%). The mean age at phacoemulsification with toric IOL implantation was 55.0 years (SD: ±14.4). The mean follow-up time was 48.2 ± 26.6 months. Preoperative mean topographic astigmatism was 6.34 ± 2.70 D (range 2-13.2 D). The mean IOL cylinder power was 6.00 ± 4.75 D (range 2-12 D). Both mean refractive astigmatism and mean refractive spherical equivalent decreased significantly from -5.30 ± 1.86 D to -1.62 ± 1.94 D ( P < 0.001) and from -4.00 ± 4.46 D to -0.25 ± 1.25 D ( P < 0.001), respectively. From preoperative to the last visit, there was a significant improvement in mean uncorrected distance visual acuity (UCVA) (from 1.3 ± 1.0 logMAR to 0.4 ± 0.3 logMAR, P < 0.001) and mean corrected distance visual acuity (CDVA) (from 0.7 ± 0.6 logMAR to 0.2 ± 0.3 logMAR, P < 0.001). Postoperative UDVA was 20/40 and 20/30 or better in 34% and 21% of eyes, respectively. Postoperative CDVA was 20/40 and 20/30 or better in 70% and 58% of eyes, respectively., Conclusions: Phacoemulsification and toric IOL implantation can effectively reduce moderate to high postkeratoplasty astigmatism, with a corresponding significant visual improvement., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.
