During routine vitreous surgery, the vitreous cavity and retina are cooled to much lower temperatures than those used in therapeutic hypothermia. Rapid rewarming occurs within the eye once the infusion line is closed.

Purpose: To quantify the differences in daily physical activity (PA) patterns, intensity-specific volumes, and PA bouts in youth with and without heart disease (HD). Methods: Seven-day PA was measured on children/adolescents with HD (n = 34; median age 12.4 y; 61.8% male; 70.6% single ventricle, 17.7% heart failure, and 11.8% pulmonary hypertension) and controls without HD (n = 22; median age 12.3 y; 59.1% male). Mean counts per minute were classified as sedentary, light, and moderate to vigorous PA (MVPA), and bouts of MVPA were calculated. PA was calculated separately for each hour of wear time from 8:00 to 22:00. Multilevel linear mixed modeling compared the outcomes, stratifying by group, time of day, and day part (presented as median percentage of valid wear time [interquartile range]). Results: Compared with the controls, the HD group had more light PA (33.9% [15%] vs 29.6% [9.5%]), less MVPA (1.7% [2.5%] vs 3.2% [3.3%]), and more sporadic bouts (97.4% [5.7%] vs 89.9% [9.2%]), but fewer short (2.0% [3.9%] vs 7.1% [5.7%]) and medium-to-long bouts (0.0% [1.9%] vs 1.6% [4.6%]) of MVPA. The HD group was less active in the late afternoon, between 15:00 and 17:00 (P < .03). There were no differences between groups in sedentary time. Conclusion: Children/adolescents with HD exhibit differences in intensity-specific volumes, PA bouts, and daily PA patterns compared with controls.

Purpose This article aims to assess ophthalmologists' practice patterns, experiences, and self-perceived skills when delivering bad news to patients and to compare this to patients' experience and preferences in receiving bad news from ophthalmologists. Design/Methods This is a prospective cross-sectional survey study of two populations: (1) Attending ophthalmologists and current ophthalmologists-in-training (N = 202) at accredited ophthalmology residency programs in the United States and Canada. (2) Patients (N = 151) 18 years of age and older at a single academic center who had received bad news from their ophthalmologist. An e-mail was sent to ophthalmology department chairs and resident program directors requesting that they distribute an online survey to their faculty, fellows, and residents. Patients were recruited from the clinics at an academic center and completed a self-administered survey before their scheduled appointments. Both populations were surveyed on their experience in breaking and receiving bad news, respectively. Questions were rated on a standard five-point Likert scale, and mean score was calculated for statistical comparison. The primary outcome variable was the quantitative rating (Likert scale 1–5) of physicians' communication skills when delivering bad news from physicians and patients' responses. Results Patients rated their physicians higher than physicians rated themselves with regard to ability to deliver bad news (mean score of 4.23 vs. 3.48, p < 0.01). Multivariate analysis showed frequent delivery of bad news (mean score of 3.66 for once per day, 3.53 for per week, 3.40 for once per month, and 3.22 for once per year, linear trend; p = 0.004) and years of practice were associated with better self-perceived ability to deliver bad news (mean score of 3.75 for ≥15 years, 3.48 for <15 years, and 3.30 for residents/fellows, linear trend; p < 0.001). Having received formal training in breaking bad news was associated with better perceived ability score, yet not statistically significant (3.51 vs. 3.39, p = 0.31). Most patients (97.5%) and physicians (92.1%) believe delivering bad news can be taught. Conclusion Physicians and patients agree that skills of delivering bad news can be learned. Patients are less critical of their physicians' ability to deliver bad news than physicians are themselves. Further study of best methods to deliver bad news is clearly indicated for the field of ophthalmology.

The seal between the TKP and cornea is established at the horizontal interface between the TKP flange and the anterior corneal surface, not between the corneal stroma and TKP trunk. The Landers wide-field TKP is a reusable model that provides a clear posterior-segment view and effectively forms a watertight eye at a sustained intraocular pressure of 100 mmHg. This TKP may be used in ocular trauma where the corneal defect is up to 0.8 mm greater in diameter than the 7.2-mm TKP trunk.
