Measuring COVID-19 Related Anxiety in Parents: Psychometric Comparison of Four Different Inventories
Authors: Kubb Christian , Foran Heather M 
Published: November 2020

BackgroundThe COVID-19 outbreak and the measures to contain the global pandemic can have an impact on the well-being and mental health status of individuals. Parents of young children are particularly at risk for high levels of parental stress due to the current public health crisis, which can impact parenting behaviors and children’s well-being. Although different initial scales have been developed to measure COVID-19–related anxiety, they have not yet been tested sufficiently in parent samples. A brief measure of COVID-19–related anxiety is necessary for both quick assessment in practice and in larger epidemiological studies of parents.ObjectiveThe purpose of this study is to compare the distributions, validities, and reliabilities of four different COVID-19 anxiety scales: Fear of COVID-19 Scale, Coronavirus Anxiety Scale, Pandemic Anxiety Scale, and one subscale of the COVID Stress Scales. Based on the psychometric properties of these scales, we aim to provide recommendations for a brief unidimensional inventory to assess COVID-19–related anxiety among parents.MethodsA cross-sectional web-based survey of 515 German-speaking parents (465 mothers, 90.3%) with at least one child aged 0-6 years was conducted during a 6-week period (June 29 to August 9, 2020). Half of the parents were recruited via Facebook parenting groups, while the other half were recruited through childcare centers. We psychometrically tested 25 items on COVID-19–related anxiety using the framework of classical test theory, including item analysis, correlational analysis of family variables, and exploratory factor analysis. Moreover, an item response theory approach was applied to estimate item discriminations and item difficulties.ResultsBased on the psychometric properties, three items of the Pandemic Anxiety Scale were identified as a single unidimensional factor. The adapted scale demonstrated acceptable internal consistency (α=.79), moderate to high item discrimination, strong positive intercorrelation with two other COVID-19 anxiety scales, and a small positive association with parenting stress. Mothers and fathers did not differ in total scores (t513=−0.79, P=.42).ConclusionsFactor analysis suggests that existing COVID-19–related anxiety scales measure different latent constructs of anxiety. Furthermore, all scales showed only small to moderate correlations with trait health anxiety, suggesting that COVID-19–related anxiety is distinct from general health anxiety. The adapted “disease anxiety” subscale of the Pandemic Anxiety Scale is an economical measure for assessing COVID-19–related anxiety in parents. Directions for future research are outlined.

Published: November 2020

Background
Despite widespread interest in the use of virtual (ie, telephone and video) visits for ambulatory patient care during the COVID-19 pandemic, studies examining their adoption during the pandemic by race, sex, age, or insurance are lacking. Moreover, there have been limited evaluations to date of the impact of these sociodemographic factors on the use of telephone versus video visits. Such assessments are crucial to identify, understand, and address differences in care delivery across patient populations, particularly those that could affect access to or quality of care.

Objective
The aim of this study was to examine changes in ambulatory visit volume and type (ie, in-person vs virtual and telephone vs video visits) by patient sociodemographics during the COVID-19 pandemic at one urban academic medical center.

Methods
We compared volumes and patient sociodemographics (age, sex, race, insurance) for visits during the first 11 weeks following the COVID-19 national emergency declaration (March 15 to May 31, 2020) to visits in the corresponding weeks in 2019. Additionally, for visits during the COVID-19 study period, we examined differences in visit type (ie, in-person versus virtual, and telephone versus video visits) by sociodemographics using multivariate logistic regression.

Results
Total visit volumes in the COVID-19 study period comprised 51.4% of the corresponding weeks in 2019 (n=80,081 vs n=155,884 visits). Although patient sociodemographics between the COVID-19 study period in 2020 and the corresponding weeks in 2019 were similar, 60.5% (n=48,475) of the visits were virtual, compared to 0% in 2019. Of the virtual visits, 61.2% (n=29,661) were video based, and 38.8% (n=18,814) were telephone based. In the COVID-19 study period, virtual (vs in-person) visits were more likely among patients with race categorized as other (vs White) and patients with Medicare (vs commercial) insurance and less likely for men, patients aged 0-17 years, 65-74 years, or ≥75 years (compared to patients aged 18-45 years), and patients with Medicaid insurance or insurance categorized as other. Among virtual visits, compared to telephone visits, video visits were more likely to be adopted by patients aged 0-17 years (vs 18-45 years), but less likely for all other age groups, men, Black (vs White) patients, and patients with Medicare or Medicaid (vs commercial) insurance.

Conclusions
Virtual visits comprised the majority of ambulatory visits during the COVID-19 study period, of which a majority were by video. Sociodemographic differences existed in the use of virtual versus in-person and video versus telephone visits. To ensure equitable care delivery, we present five policy recommendations to inform the further development of virtual visit programs and their reimbursement.

Published: November 2020

Background and objectives
Coronavirus disease 2019 (COVID-19) is associated with higher risk of AKI. We aimed to describe rates and characterize predictors and health outcomes associated with AKI in a national cohort of US veterans hospitalized with COVID-19.

Design, setting, participants, & measurements
In a cohort of 5216 US veterans hospitalized with COVID-19 identified through July 23, 2020, we described changes in serum creatinine and examined predictors of AKI and the associations between AKI, health resource utilization, and death, utilizing logistic regressions. We characterized geographic and temporal variations in AKI rates and estimated variance explained by key variables utilizing Poisson regressions.

Results
In total, 1655 (32%) participants had AKI; 961 (58%), 223 (13%), and 270 (16%) met Kidney Disease Improving Global Outcomes definitions of stage 1, 2, and 3 AKI, respectively, and 201 (12%) received KRT. Eight percent of participants had AKI within 1 day of hospitalization, and 47% did not recover to baseline serum creatinine by discharge. Older age, Black race, male gender, obesity, diabetes, hypertension, and lower eGFR were significant predictors of AKI during hospitalization with COVID-19. AKI was associated with higher mechanical ventilation use (odds ratio, 6.46; 95% confidence interval, 5.52 to 7.57) and longer hospital stay (5.56 additional days; 95% confidence interval, 4.78 to 6.34). AKI was also associated with higher risk of death (odds ratio, 6.71; 95% confidence interval, 5.62 to 8.04); this association was stronger in Blacks (P value of interaction <0.001). Hospital-level rates of AKI exhibited substantial geographic variability, ranging from 10% to 56%. Between March and July 2020, AKI rates declined from 40% to 27%; proportions of AKI stage 3 and AKI requiring KRT decreased from 44% to 17%. Both geographic and temporal variabilities were predominately explained by percentages of Blacks (31% and 49%, respectively).

Conclusions
AKI is common during hospitalization with COVID-19 and associated with higher risk of health care resource utilization and death. Nearly half of patients with AKI did not recover to baseline by discharge. Substantial geographic variation and temporal decline in rates and severity of AKI were observed.

OBJECTIVE
Continuous glucose monitoring (CGM) reduces HbA1c and time spent in hypoglycemia in people with type 1 diabetes (T1D) treated with multiple daily insulin injections (MDI) when evaluated over shorter time periods. It is unclear to what extent CGM improves and helps to maintain glucose control, treatment satisfaction, diabetes distress, hypoglycemic concerns, and overall well-being over longer periods of time.

RESEARCH DESIGN AND METHODS
The GOLD trial was a randomized crossover trial performed over 16 months of CGM treatment in people with T1D treated with MDI. People completing the trial (n = 141) were invited to participate in the current SILVER extension study in which 107 patients continued CGM treatment over 1 year along with the support of a diabetes nurse every 3 months.

RESULTS
The primary end point of the change in HbA1c over 1.0–1.5 years of CGM use compared with previous self-monitoring of blood glucose during GOLD showed a decrease in HbA1c of 0.35% (95% CI 0.19–0.50, P &lt; 0.001). Time spent in hypoglycemia &lt;3.0 mmol/L (54 mg/dL) and &lt;4.0 mmol/L (72 mg/dL) decreased from 2.1% to 0.6% (P &lt; 0.001) and from 5.4% to 2.9% (P &lt; 0.001), respectively. Overall well-being (World Health Organization 5-item well-being index, P = 0.009), treatment satisfaction (Diabetes Treatment Satisfaction Questionnaire, P &lt; 0.001), and hypoglycemic confidence (P &lt; 0.001) increased, while hypoglycemic fear (Hypoglycemia Fear Survey–Worry, P = 0.016) decreased and diabetes distress tended to decrease (Problem Areas in Diabetes Scale, P = 0.06). From randomization and screening in GOLD, HbA1c was lowered by 0.45% (P &lt; 0.001) and 0.68% (P &lt; 0.001) after 2.3 and 2.5 years, respectively.

CONCLUSIONS
The SILVER study supports beneficial long-term effects from CGM on HbA1c, hypoglycemia, treatment satisfaction, well-being, and hypoglycemic confidence in people with T1D managed with MDI.

Investment decision involves risk and uncertainty. An investor makes the choice of where and what to commit funds into for future returns. Studies have shown that due to pressure to satisfy investors’ desire and to make their company attractive to investors, corporate managers manipulate financial books and pay dividends to shareholders on profits not earned. This practice may lead to wrong investment decisions by investors. This study examined corporate governance and investors’ decision in quoted deposit money banks in Nigeria.
Ex-post facto research design was employed. The research population comprised the fifteen deposit money banks quoted on the Nigerian Stock Exchange as of December 31, 2017. Total enumeration method was used. Validated data were obtained from the Nigerian Stock Exchange and audited financial statements of the sampled deposit money banks. The data were analyzed using descriptive and inferential statistics.
Results indicated that corporate governance proxies of board size, board composition and audit quality jointly had a significant and positive effect on volume of shares traded (F(4,130) =13.43; Adj. R2 = 0.0753; p = 0.0093); corporate governance and control variables of firm size and profitability had a joint and positive effect on volume of shares traded (F(6,126) =20.15; Adj. R2 = 0.0654; p = 0.0026).
The study concluded that corporate governance affects volume of shares traded and firm size and profitability of firms have controlling influence on volume of shares traded. Management and board of directors should imbibe transparent corporate governance culture in their organizations to attract investors when making investment decision.
Éros el memorioso

La vinculación entre el amor y la memoria es parte de toda experiencia humana. Rescataré aquí elementos que la cultura helena y la filosofía platónica nos aportan para reflexionar sobre esta vivencia universal. Para ello rastrearé el nexo que la tradición griega establecía entre la memoria, en tanto acopio del acervo cultural y capacidad individual de preservar conocimientos, y el amor como la emoción que nos afecta en el estado enamoramiento pero que tenía también una proyección política y cósmica. Luego, exploraré la concepción platónica del amor como fuerza que constituye la existencia humana y cuya tarea de procreación en la belleza contribuye a la formación de la memoria colectiva e individual, y, a través de ella, de la identidad personal. Finalmente, referiré a la reminiscencia como recuperación del conocimiento del entramado de la realidad done el enamoramiento es un facilitador para la rememoración de la belleza pura y eterna.
