RESUMEN

STUDY DESIGN: Cross-sectional, observational study. OBJECTIVES: To determine whether changes in essential care during the COVID-19 pandemic impacted satisfaction with activities, participation, and relationships among individuals with spinal cord injury (SCI). SETTING: Data were collected online between December 31, 2020 and February 14, 2021 among community dwelling adults with SCI (N = 123). METHODS: The primary outcome variables were satisfaction with the ability to complete activities of daily living (ADLs) (mobility, dressing, feeding, and toileting), as well as satisfaction with participation in household and recreational activities, and satisfaction with relationships among friends, family, and with the status of one's relationship measured with the International Spinal Cord Injury Data Sets Activities and Participation Basic Data Set. Primary predictors were age, gender, time since injury, completeness of injury, injury level, access to mental health, access to medications, access to medical supplies, and access to personal care assistants (PCAs). RESULTS: Impact on access to mental health and impact on access to supplies were the most common factors affecting satisfaction with activities, participation, and relationships for individuals with SCI during the COVID-19 pandemic. Impact on access to PCAs/homecare was also found to impact certain outcomes including feeding and participation in household activities. CONCLUSIONS: Future supply chain disruptions from pandemics or natural disasters could have wide-reaching effects for individuals with SCIs. Thus, further research and advocacy is needed to improve mental health care planning and supply chain access during subsequent natural disasters.

RESUMEN

Background and Objectives: To determine the percentage of the healthy population that responds asymmetrically to the red desaturation test and to approximate the degree of red desaturation in those individuals. We also sought to elucidate any correlation between demographic variables and red desaturation prevalence and severity. Methods: Adults aged 18 years and older with a normal eye examination, including confrontation fields and best-corrected visual acuity of ≥20/25 in both eyes, were eligible for this prevalence study. Those with objective or subjective afferent visual dysfunction were excluded. A total of 101 eligible participants (68.3% female and 31.7% male; racial/ethnic breakdown of 77.2% White, 11.9% Black, 8.9% Asian, 2.0% N/A; mean (SD) age: 41.5 (15.3) years) were queried whether the monocular perception of redness of a standardized tropicamide bottle cap was the same and to estimate the interocular percentage difference, with 1 eye perceiving the bottle cap at "100% redness." Results: Twenty-four participants (23.8%) experienced some degree of red desaturation. For these individuals with red desaturation, the average interocular difference was 9.0% (range 2%-25%, 95% confidence interval 6.0%-12.0%). There was no statistical evidence for a relationship between red desaturation and race, sex, or age. Discussion: This study shows that nearly a quarter of healthy patients without apparent optic nerve or macular dysfunction may recognize red desaturation. This deserves consideration when interpreting red desaturation testing in patients suspected to have unilateral optic neuropathy. Further research with larger sample sizes may identify predictors of red desaturation in healthy patients, establish the red desaturation threshold separating pathologic from physiologic phenomena, and assess the repeatability of red desaturation over time in affected individuals.

RESUMEN

STUDY DESIGN: Cross-sectional, observational study. OBJECTIVES: To understand how resilience, access to personal care attendants (PCAs) and medical supplies, and concerns about medical rationing, finances, and social isolation are related to overall and mental health in individuals with spinal cord injury (SCI) in the context of the COVID-19 pandemic. SETTING: Community dwelling adults (N = 187) with SCI. METHODS: Data were collected online between May 1, 2020 and August 31, 2020. Outcomes were overall and mental health, depression and anxiety symptoms, and quality of life (QoL). Predictors were resilience, access to PCAs and medical supplies, and concerns about medical rationing, finances, and social isolation. RESULTS: Incomplete injury, concern about medical rationing, medical supply disruption, and social isolation predicted a greater perceived impact of the pandemic on overall heath. Younger age, decreased resilience, and concern about medical rationing and social isolation predicted greater perceived impact of the pandemic on mental health. Decreased resilience and concern about medical rationing and finances predicted increased anxiety symptoms. Incomplete injury, believing that medical rationing was occurring, decreased resilience, and concern about finances and social isolation predicted increased depressive symptoms. Decreased resilience and concern about finances, medical rationing, and social isolation predicted lower QoL. CONCLUSIONS: The negative effects of the pandemic on the overall and mental health of individuals with SCI may be ameliorated by resilience. In future crises, it may be beneficial to screen individuals for resilience so that those with decreased resilience are offered the appropriate resources to enhance resilience and improve overall wellbeing.

RESUMEN

PURPOSE: To determine the percent adherence to follow-up for patients with pediatric glaucomas seen at a tertiary care center and to elucidate risk factors. DESIGN: Retrospective cohort study. METHODS: Patients with pediatric glaucomas seen at the University of Minnesota over 8.5 years were classified as adherent, nonadherent, or lost to tertiary follow-up if they followed up within 0-30 days, between 31 and 180 days, or later than 180 days of the recommended appointment time or never, respectively. RESULTS: Of 176 patients analyzed, 95 (54%) were adherent (51% male; mean [standard deviation (SD)] age: 56.1 [59.8] months), 5 (3%) were nonadherent (20% male; mean [SD] age: 25.0 [35.8] months), and 76 (43%) were lost to tertiary follow-up (55% male; mean [SD] age: 58.9 [53.1] months). Multiple logistic regression analysis of variables that were significant in isolation revealed that only race (white: odds ratio, 3.58; 95% confidence interval, 1.42-9.05; P = .007) and distance from the eye clinic (per 50 miles: odds ratio, 0.79; 95% confidence interval, 0.67-0.92; P = .003) significantly impacted adherence. CONCLUSIONS: This is the first study of adherence to follow-up recommendations for patients with pediatric glaucomas. Percent adherence to follow-up appointments was alarmingly low, and decreased adherence was observed with non-white race and increased distance to the eye clinic. Physicians should consider these risk factors when risk-stratifying patients with pediatric glaucomas for nonadherence to follow-up. Additional studies to improve adherence through interventions that reduce biases and barriers to follow-up are needed.

RESUMEN

Piriformospora indica, a root endophytic fungus, has been shown to enhance biomass production and confer tolerance to various abiotic and biotic stresses in many plant hosts. A growth chamber experiment of soybean (Glycine max) colonized by P. indica compared to uninoculated control plants showed that the fungus significantly increased shoot dry weight, nutrient content, and rhizobial biomass. RNA-Seq analyses of root tissue showed upregulation of 61 genes and downregulation of 238 genes in colonized plants. Gene Ontology (GO) enrichment analyses demonstrated that upregulated genes were most significantly enriched in GO categories related to lignin biosynthesis and regulation of iron transport and metabolism but also mapped to categories of nutrient acquisition, hormone signaling, and response to drought stress. Metabolic pathway analysis revealed upregulation of genes within the phenylpropanoid and derivative pathways such as biosynthesis of monolignol subunits, flavonoids and flavonols (luteolin and quercetin), and iron scavenging siderophores. Highly enriched downregulated GO categories included heat shock proteins involved in response to heat, high-light intensity, hydrogen peroxide, and several related to plant defense. Overall, these results suggest that soybean maintains an association with this root endosymbiotic fungus that improves plant growth and nutrient acquisition, modulates abiotic stress, and promotes synergistic interactions with rhizobia.
