The effect of activity and face masks on exhaled particles in children.

Importance: Despite the high burden of respiratory infections among children, the production of exhaled particles during common activities and the efficacy of face masks in children have not been sufficiently studied. Objective: To determine the effect of type of activity and mask usage on exhaled particle production in children. Methods: Healthy children were asked to perform activities that ranged in intensity (breathing quietly, speaking, singing, coughing, and sneezing) while wearing no mask, a cloth mask, or a surgical mask. The concentration and size of exhaled particles were assessed during each activity. Results: Twenty-three children were enrolled in the study. Average exhaled particle concentration increased by intensity of activity, with the lowest particle concentration during tidal breathing (1.285 particles/cm3 [95% CI 0.943, 1.627]) and highest particle concentration during sneezing (5.183 particles/cm3 [95% CI 1.911, 8.455]). High-intensity activities were associated with an increase primarily in the respirable size (≤ 5 µm) particle fraction. Surgical and cloth masks were associated with lower average particle concentration compared to no mask (P = 0.026 for sneezing). Surgical masks outperformed cloth masks across all activities, especially within the respirable size fraction. In a multivariable linear regression model, we observed significant effect modification of activity by age and by mask type. Interpretation: Similar to adults, children produce exhaled particles that vary in size and concentration across a range of activities. Production of respirable size fraction particles (≤ 5 µm), the dominant mode of transmission of many respiratory viruses, increases significantly with coughing and sneezing and is most effectively reduced by wearing surgical face masks.

Pregnant individual's lived experience of cannabis use during the COVID-19 pandemic: a qualitative study.

Introduction: Quantitative studies indicate that the COVID-19 pandemic has contributed to increased rates of prenatal cannabis use. However, little is known about how the pandemic has impacted cannabis use from the perspective of pregnant individuals themselves. Our objective was to characterize COVID-19-related changes in cannabis use among pregnant individuals who used cannabis during the pandemic. Methods: We conducted 18 focus groups (from 11/17/2021 to 12/17/2021) with Black and White pregnant individuals aged 18+ who self-reported prenatal cannabis use during universal screening at entrance to prenatal care (at ~8 weeks gestation) in Kaiser Permanente Northern California. Virtual focus groups were transcribed and analyzed using thematic analysis. Results: The sample of 53 pregnant individuals (23 Black, 30 White) was 30.3 years old (SD = 5.2) on average, and most (70%) self-reported daily versus weekly or monthly prenatal cannabis use. Major themes regarding the impact of the pandemic on cannabis use included increases in use (resulting from depression, anxiety, stress, boredom), and changes in social use (less sharing of smoked cannabis products), modes of use (from smoking to other modes due to respiratory concerns) and source (from storefront retailers to delivery). Conclusion: Coping with mental health symptoms and stress were identified drivers of perceived pandemic-related increases in prenatal cannabis use in 2021. Pregnant individuals adapted their use in ways consistent with public health recommendations to decrease social contact and reduce or quit smoking to mitigate COVID-19 transmission and harms. Proactive, mental health outreach for pregnant individuals during future pandemic waves may reduce prenatal cannabis use.

Measuring Zoom Fatigue in College Students: Development and Validation of the Meeting Fatigue Scale for Videoconferencing (MFS-V) and the Meeting Fatigue Scale for In-Person (MFS-I)

The COVID-19 pandemic saw a significant growth in the usage of videoconferencing platforms such as Zoom in academia – accompanied by greater reports of exhaustion and burnout associated with extensive video meetings from college students. Given that videoconferencing adoption will likely persist, it is critical to develop a psychometrically sound tool for the measurement of "Zoom fatigue.” However, current measures for Zoom fatigue fail to control for similarities to in-person meeting fatigue. Thus, we designed and validated a scale to measure Zoom fatigue, the Meeting Fatigue Scale for Videoconferencing (MFS-V) along with a companion scale to measure in-person meeting fatigue, the Meeting Fatigue Scale for In-Person (MFS-I). Exploratory factor analyses (EFA) revealed that the MFS-V and MFS-I had different factor structures, and provided evidence that Zoom fatigue is a conceptually distinct phenomenon from in-person meeting fatigue. This finding was supported by confirmatory factor analyses (CFA) that supported the fit of both factor structures. Both scales demonstrated strong reliability, convergent validity, divergent validity, and incremental validity over measures of general burnout and meeting duration and frequency. These results suggest the MFS-V and MFS-I are effective tools for assessing and understanding fatigue and burnout related to videoconferencing and in-person meeting attendance for students.

The screening and the access to ICU

A novel coronavirus was identified in late 2019 as the cause of a cluster of pneumonia cases in Wuhan, China. It has since rapidly spread resulting in a pandemic. The World Health Organization designated the disease term COVID-19 (Coronavirus Disease 2019). The virus that causes COVID-19 is designated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The major morbidity and mortality from COVID-19 is largely due to acute viral pneumonitis that evolves to acute respiratory distress syndrome (ARDS). © Springer Nature Switzerland AG 2020.

Association of the COVID-19 Pandemic With Unstable and/or Unsafe Living Situations and Intimate Partner Violence Among Pregnant Individuals.

Importance: The social, behavioral, and economic consequences of the COVID-19 pandemic may be associated with unstable and/or unsafe living situations and intimate partner violence (IPV) among pregnant individuals. Objective: To investigate trends in unstable and/or unsafe living situations and IPV among pregnant individuals prior to and during the COVID-19 pandemic. Design, Setting, and Participants: A cross-sectional population-based interrupted time-series analysis was conducted among Kaiser Permanente Northern California members who were pregnant and screened for unstable and/or unsafe living situation and IPV as part of standard prenatal care between January 1, 2019, and December 31, 2020. Exposures: COVID-19 pandemic (prepandemic period: January 1, 2019, to March 31, 2020; during pandemic period: April 1 to December 31, 2020). Main Outcomes and Measures: The 2 outcomes were unstable and/or unsafe living situations and IPV. Data were extracted from electronic health records. Interrupted time-series models were fit and adjusted for age and race and ethnicity. Results: The study sample included 77 310 pregnancies (74 663 individuals); 27.4% of the individuals were Asian or Pacific Islander, 6.5% were Black, 29.0% were Hispanic, 32.3% were non-Hispanic White, and 4.8% were other/unknown/multiracial, with a mean (SD) age of 30.9 (5.3) years. Across the 24-month study period there was an increasing trend in the standardized rate of unsafe and/or unstable living situations (2.2%; rate ratio [RR], 1.022; 95% CI, 1.016-1.029 per month) and IPV (4.9%; RR, 1.049; 95% CI, 1.021-1.078 per month). The ITS model indicated a 38% increase (RR, 1.38; 95% CI, 1.13-1.69) in the first month of the pandemic for unsafe and/or unstable living situation, with a return to the overall trend afterward for the study period. For IPV, the interrupted time-series model suggested an increase of 101% (RR, 2.01; 95% CI, 1.20-3.37) in the first 2 months of the pandemic. Conclusions and Relevance: This cross-sectional study noted an overall increase in unstable and/or unsafe living situations and IPV over the 24-month period, with a temporary increase associated with the COVID-19 pandemic. It may be useful for emergency response plans to include IPV safeguards for future pandemics. These findings suggest the need for prenatal screening for unsafe and/or unstable living situations and IPV coupled with referral to appropriate support services and preventive interventions.

Association of cannabis use during pregnancy with severe acute respiratory syndrome coronavirus 2 infection: a retrospective cohort study.

BACKGROUND AND AIMS: Cannabis use is increasingly common among pregnant individuals and might be a risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We aimed to test whether prenatal cannabis use is associated with increased risk of SARS-CoV-2 infection during pregnancy. DESIGN: This is a retrospective cohort study. SETTING: The study was conducted in California, USA. PARTICIPANTS: A total of 58 114 pregnancies (with outcomes from 5 March 2020 to 30 September 2021) among 57 287 unique pregnant women aged 14-54 years who were screened for prenatal substance use, enrolled in Kaiser Permanente Northern California (KPNC) (a health-care system) and had not tested positive for COVID-19 prior to pregnancy onset. MEASUREMENTS: We utilized data from the KPNC electronic health record. Cannabis use status (current, recently quit and non-user) was based on universal screenings during prenatal care (including urine toxicology testing and self-reported use on a self-administered questionnaire). SARS-CoV-2 infection [based on polymerase chain reaction (PCR) tests] was estimated in time-to-event analyses using Cox proportional hazard regression models adjusting for covariates. Secondary analyses examined differences in (a) SARS-CoV-2 testing rates and (b) SARS-CoV-2 infection rates among those tested. FINDINGS: We observed 348 810 person-months of follow-up time in our cohort with 41 064 SARS-CoV-2 PCR tests and 6% (n = 2414) of tests being positive. At the start of follow-up, 7% of pregnant individuals had current use, 12% had recently quit and 81% did not use cannabis. Adjusting for covariates, current use was associated with lower rates of SARS-CoV-2 infection [adjusted hazard ratio (aHR) = 0.60, 95% confidence interval (CI) = 0.49-0.74 than non-use. Those who had recently quit did not differ from non-cannabis users in infection rates (aHR = 0.96, 95% CI = 0.86-1.08). Sensitivity analyses among patients who received a SARS-CoV-2 test also found lower odds of infection associated with current versus no cannabis use (aOR = 0.76, CI = 0.61-0.93). CONCLUSIONS: Current cannabis use appears to be associated with a reduced risk of SARS-CoV-2 infection among pregnant individuals.

"Just being there, like a shoulder to lean on": Resilience and Mental Health among Older Youth in and Aged out of Foster Care during COVID-19.

Disasters share a common potential for significant ecological and psychosocial disruption at the individual, community, and societal levels, and are especially harmful to members of social groups in vulnerable situations, including youth in foster care and those recently emancipated from care. These young people are susceptible to mental health challenges and understanding their resiliency is key to mitigating pandemic-related harms. This qualitative study aims to (1) understand how the COVID-19 pandemic affected the mental health of older youth between the ages of 18 and 23 (M = 20.5 years, S.D. = 1.7 years), currently in or aged out of foster care (M = 5.9 years in care, S.D. = 4.4 years), and experiencing mental health challenges, and (2) gain insight into the resiliency that supports young people in dealing with these challenges. Twenty-six young people (77% female-identifying, 38% White, 27% Hispanic) in the USA participated in in-depth interviews. Salient themes include: 1) supportive relationships, 2) adaptive coping skills and mindsets, and 3) environmental, institutional, and social supports. Results amplify the voices of these young people concerning the impact of COVID-19 on their mental health and foreground the dynamic strategies they are using to alleviate their distress.

Geographic Accessibility of Retail Cannabis in Northern California and Prenatal Cannabis Use During the COVID-19 Pandemic.

Importance: Prenatal cannabis use is associated with health risks for mothers and their children. Prior research suggests that rates of prenatal cannabis use in Northern California increased during the COVID-19 pandemic, but it is unknown whether increases varied with the local cannabis retail and policy environment. Objective: To test whether pandemic-related increases in prenatal cannabis use were greater among pregnant individuals with greater retail availability of cannabis around their homes or among those living in jurisdictions that allowed storefront retailers. Design, Setting, and Participants: A cross-sectional, population-based time series study used data from pregnancies in the Kaiser Permanente Northern California health care system screened for cannabis use before (January 1, 2019, to March 31, 2020) and during (April 1 to December 31, 2020) the early COVID-19 pandemic. Proximity to the nearest retailer and number of retailers within a 15-minute drive from one's home and local cannabis storefront retailer policy (banned vs permitted) were calculated. Interrupted time series models were fit using multiplicative and additive Poisson regression, adjusting for age and race and ethnicity. Exposures: The COVID-19 pandemic. Main Outcomes and Measures: Prenatal cannabis use based on universal urine toxicology tests conducted during early pregnancy at entrance to prenatal care. Results: The sample (n = 99 127 pregnancies) included 26.2% Asian or Pacific Islander, 6.8% Black, 27.6% Hispanic, 34.4% non-Hispanic White, and 4.9% other, unknown, or multiracial individuals, with a mean (SD) age of 30.8 (5.3) years. Prenatal cannabis use before (6.8%) and during (8.2%) the pandemic was associated with closer proximity to a retailer, greater retailer density, and residing in a jurisdiction that permitted vs banned retailers. There was a greater absolute increase in cannabis use from before to during the pandemic among those within a 10-minute drive (<10 minutes: adjusted rate difference [aRD], 0.93 cases/100 patients; 95% CI, 0.56-1.29 cases/100 patients; ≥10 minutes: aRD, 0.40 cases/100 patients; 95% CI, 0.12-0.68 cases/100 patients; interaction P = .02). Otherwise, relative and absolute rates increased similarly across categories of cannabis retailer proximity/density and local policy (interaction P > .05). Conclusions and Relevance: Prenatal cannabis use was more common among individuals living in areas with greater retail availability of cannabis. Although relative rates increased similarly during the pandemic regardless of local cannabis retail and policy environment, there was a larger absolute increase associated with living closer to a storefront cannabis retailer. Continued monitoring of local cannabis policy, the retail environment, and prenatal cannabis use is needed.

Keep It Brief: Videoconferencing Frequency and Duration as Predictors of Visual and Body Discomfort

The recent COVID-19 pandemic has led to a drastic increase in the frequency of videoconferencing used for work, school, and socialization. To date, the user experience impact of this increased screen time is unknown. We surveyed 489 participants (M age = 24.19, Range = 18–72) to determine which factors best predict visual and body discomfort. Along with gender, screen time, and level of subjective meeting fatigue, meeting duration significantly predicted visual discomfort. In contrast, meeting frequency (along with the level of meeting engagement, subjective meeting fatigue, and other covariates) significantly predicted bodily discomfort. These results highlight the need for greater ergonomic evaluation of work-from-home setups, as well as point to a need for shorter, fewer, and more engaging video meetings for the average worker from home.

Altered Accumbal Dopamine Terminal Dynamics Following Chronic Heroin Self-Administration.

Administration of heroin results in the engagement of multiple brain regions and the rewarding and addictive effects are mediated, at least partially, through activation of the mesolimbic dopamine system. However, less is known about dopamine system function following chronic exposure to heroin. Withdrawal from chronic heroin exposure is likely to drive a state of low dopamine in the nucleus accumbens (NAc), as previously observed during withdrawal from other drug classes. Thus, we aimed to investigate alterations in NAc dopamine terminal function following chronic heroin self-administration to identify a mechanism for dopaminergic adaptations. Adult male Long Evans rats were trained to self-administer heroin (0.05 mg/kg/inf, IV) and then placed on a long access (FR1, 6-h, unlimited inf, 0.05 mg/kg/inf) protocol to induce escalation of intake. Following heroin self-administration, rats had decreased basal extracellular levels of dopamine and blunted dopamine response following a heroin challenge (0.1 mg/kg/inf, IV) in the NAc compared to saline controls. FSCV revealed that heroin-exposed rats exhibited reduced stimulated dopamine release during tonic-like, single-pulse stimulations, but increased phasic-like dopamine release during multi-pulse stimulation trains (5 pulses, 5-100 Hz) in addition to an altered dynamic range of release stimulation intensities when compared to controls. Further, we found that presynaptic D3 autoreceptor and kappa-opioid receptor agonist responsivity were increased following heroin self-administration. These results reveal a marked low dopamine state following heroin exposure and suggest the combination of altered dopamine release dynamics may contribute to increased heroin seeking.

Low-skill no more! essential workers, social reproduction and the legitimacy-crisis of the division of labour

Workers in the realm of social reproduction - e.g. nurses, carers, cleaners, food preparation workers etc. - are considered low-skill and are poorly remunerated. During the Covid-19 crisis they have been recast as 'essential', leading to unprecedented praise and attention in public discourse. Nonetheless, public praise for these 'essential' workers so far has not translated into a commitment for higher wages and improved working conditions. In this article, we argue that skills hierarchies continue to determine labour market outcomes and social inequalities. We pinpoint that these are embedded into the logic of capitalist social relations, rather than being an expression of the features of jobs themselves. We also show how some socially reproductive sectors resist the tendency to automation precisely because of the prevalence therein of a workforce which is portrayed as un-skilled. By focussing on low-skilled workers' engagement in various forms of labour unrest and their demands for long overdue recognition and wage rises. the article puts into question the inherited skills-lexicon according to which low-wage jobs are unproductive and lacking in skills and competence. The authors conclude that these workers' fights for the recognition of the dignity and importance of their jobs and professions can facilitate a rethinking of the division of labour in our societies.

Editorial: The times they are a-changin': paradigm shifts in child and adolescent psychology and psychiatry.

The world is a different place than it was more than 2 years ago, at the start of the COVID-19 pandemic. The times are always changing, but events of the recent past have radically shifted how we work, when and how we interact with each other, and how we understand our history. The papers in the current issue echo this spirit of change, challenging us to fundamentally re-think how we conceptualize psychopathology, where we define boundaries between 'normal' and 'abnormal' (and, who gets to define those boundaries), and whether our current conceptual models are generalizable to ever more diverse groups. These challenges represent healthy and timely critiques of dominant paradigms. Collectively, the authors who contributed to the current Annual Research Review make the case that these new frameworks will have big pay-offs in terms of improving clinical practice and policy.

The experiences of older youth in and aged out of foster care during the COVID-19 pandemic: Material and financial well-being by foster care status, gender identity, sexual orientation, ethnicity, and race.

As a marginalized, underresourced population, older youth with foster care experience are acutely vulnerable to the economic and social harms wrought by coronavirus disease 2019 (COVID-19). This study summarizes findings from an online survey deployed in April 2020 to learn about the experiences of current and former foster youth (ages 18-23) during 1 month of the COVID-19 crisis. Using snowball sampling and a cross-sectional design, the survey yielded a final analysis sample of 281 respondents from 32 states and 192 cities or districts. Findings underscore the pervasive negative impacts of COVID-19 on respondents' housing/living situations, food security, employment, and financial stability. Chi-square tests and post hoc analyses revealed demographic disparities in respondents' experiences during COVID-19. Youth who aged out of care, cisgender females, nonstraight youth, and non-White youth were significantly more likely than demographic counterparts to experience pandemic-related adversities. Implications for policy and practice are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
