School Connectedness Still Matters: The Association of School Connectedness and Mental Health During Remote Learning Due to COVID-19.

School connectedness is consistently associated with adolescent mental health and well-being. We investigated whether student perceptions of school connectedness were associated with anxiety and depressive symptoms, even during remote learning due to COVID-19. In June of 2020, after 13 weeks of remote learning, 320 middle and high school students in one Massachusetts school district completed an online survey that included questions about their perceptions of school connectedness, social connectedness, and symptoms of anxiety and depression. Students were approximately evenly distributed across grades, with 37% in middle school (grades 6-8) and 63% in high school (grades 9-12). School connectedness had a significant negative association with symptoms of anxiety and depression. This association persisted in models controlling for demographic factors and social connectedness. Findings indicate that school connectedness is associated with student mental health, even in the context of remote learning due to COVID-19. Schools engaged in remote learning should consider how to foster school connectedness as a means of supporting youth mental health, particularly given expected increases in the mental health needs of adolescents.

Factors predicting the ocular surface response to desiccating environmental stress.

PURPOSE: To identify factors predicting the ocular surface response to experimental desiccating stress. METHODS: The ocular surfaces of both eyes of 15 normal and 10 dry eye subjects wearing goggles were exposed to a controlled desiccating environment (15%-25% relative humidity and 2-5 L/min airflow) for 90 minutes. Eye irritation symptoms, blink rate, tear meniscus dimensions, noninvasive (RBUT) and invasive tear break-up time, and corneal fluorescein and conjunctival lissamine green-dye staining were recorded before and after desiccating stress. Pre- and postexposure measurements were compared, and Pearson correlations between clinical parameters before and after desiccating stress were calculated. RESULTS: Corneal and conjunctival dye staining significantly increased in all subjects following 90-minute exposure to desiccating environment, and the magnitude of change was similar in normal and dry eye subjects; except superior cornea staining was greater in dry eye. Irritation severity in the desiccating environment was associated with baseline dye staining, baseline tear meniscus height, and blink rate after 45 minutes. Desiccation-induced change in corneal fluorescein staining was inversely correlated to baseline tear meniscus width, whereas change in total ocular surface dye staining was inversely correlated to baseline dye staining, RBUT, and tear meniscus height and width. Blink rate from 30 to 90 minutes in desiccating environment was higher in the dry eye than normal group. Blink rate significantly correlated to baseline corneal fluorescein staining and environmental-induced change in corneal fluorescein staining. CONCLUSIONS: Ocular surface dye staining increases in response to desiccating stress. Baseline ocular surface dye staining, tear meniscus height, and blink rate predict severity of ocular surface dye staining following exposure to a desiccating environment.
