Screening parent-adolescent relationships, screen behaviors, tridimensional acculturation, and health among Black immigrant and refugee adolescents during dual pandemics.

This brief report assesses parent-adolescent relationships, screen behaviors, and tridimensional acculturation as risk and promotive or protective factors for health among Black U.S. immigrant or refugee adolescents during the dual COVID-19 and racism or Whiteness pandemics.

Editorial: Benign Versus Problematic Media Use Profiles in Youth: Correlates, Concerns, and Future Directions.

The potential impact of screen media activity (SMA) on youth development is a topic of heated debate, with inconsistent findings and concerns about SMA measurement. There is a growing call for more precise measurement and analyses of SMA, focusing more on how (in what way youth are using screens) and less on how much (aggregate screen time). There is also a need to distinguish normative vs problematic SMA (eg, addiction-like behaviors) in youth.

Cultural differences in earliest memory reports by European and Chinese American university students born in the United States.

Grounded by the ecological systems perspectives proposed by Bronfenbrenner (1977, 1979) and Fivush and Merrill (2016), the present study was conducted to examine whether autobiographical memory (AM) and self-construal differed in young adults raised in the same macrosystem, but with unique microsystems. European American (EA) participants were born in the United States to mothers who were born in the United States ( = 61) and Chinese American (CA) participants were born in the United States to mothers who were born in China ( = 47). Participants completed an online study in which they reported on and rated aspects of their earliest memory; they also completed measures of self-construal and acculturation.

Remote acculturation and physical activity among adolescent-mother dyads in Jamaica: A developmental dyadic moderation.

This study examined the associations between remote acculturation to European American culture, hereafter United States (U.S.) American culture, and physical activity levels among Jamaican mother-adolescent dyads.

Addressing Trauma in Adaptive Physical Activity: A Call to Reflection and Action.

Trauma is pervasive, embodied, and can be perpetrated or perpetuated by researchers, educators, and practitioners, including those within adaptive physical activity (APA). In this article, we highlight the need to address trauma within APA as a matter of access and justice. We share various conceptualizations of trauma from psychiatric, embodied, anti-pathologizing, and sociopolitical perspectives.

Family resilience and psychological distress in the COVID-19 pandemic: A mixed methods study.

Many changes were thrust upon families by the COVID-19 pandemic, including mandated quarantines, social distancing, transitions to distance learning for children, and remote work. The current study used mixed methods to examine the challenges and resilience of families in the United States during the pandemic (May-July 2020), as well as predictors and moderators of parent/child psychological distress. Our sample included 469 parents (459 mothers) of children aged ∼2-13 years (239 girls, 228 boys, one nonbinary child, one "prefer not to answer" selection), who completed an online survey with closed-ended and open-ended portions.

Children's screen and problematic media use in the United States before and during the COVID-19 pandemic.

This mixed methods study examined parent-reported child screen media use before and during the COVID-19 pandemic by examining 2019-2020 changes in parent perceptions of media, screen media use (SMU), and problematic media use (PMU) in children aged 2-13 years (N = 129; 64 boys, 64 girls, 1 nonbinary; 90.7% White, 4.6% Hispanic/Latino, 0.

Singing and Dancing With Neuromuscular Conditions: A Mixed-Methods Study.

The purpose of this study was to assess the safety and meaningfulness of a 15-week recreational dance and singing program for people with neuromuscular conditions. Within a transformative mixed-methods design, pulmonary function tests, plethysmography through wearable technology (Hexoskin vests), individualized neuromuscular quality-of-life assessments (version 2.0), and semistructured interviews were used.

Assessment of a Comprehensive Early Childhood Education Program and Cardiovascular Disease Risk in Midlife.

Importance: Educational attainment is an underrecognized factor associated with racial disparities in cardiovascular disease (CVD) risk. Early childhood programs providing comprehensive family services can promote educational and socioeconomic success, but few, if any, studies of large-scale programs have assessed their associations with midlife CVD risk and mediating factors.

Objective: To examine the association between an early childhood program providing multisystemic services from ages 3 to 9 years with midlife CVD risk and whether years of education mediate these associations.

The Whiteness pandemic behind the racism pandemic: Familial Whiteness socialization in Minneapolis following #GeorgeFloyd's murder.

Family socialization into the centuries-old culture of Whiteness-involving colorblindness, passivity, and fragility-perpetrates and perpetuates U.S. racism, reflecting an insidious Whiteness pandemic.

A Comprehensive, Multisystemic Early Childhood Program and Obesity at Age 37 Years.

This cohort study analyzes reductions in obesity rates at age 37 years among individuals who participated in a multisystemic Child-Parent Center preschool program.

Care haunts, hurts, heals: The promiscuous poetics of queer crip Mad care.

Care is a dirty word for many in our communities. "Caregiving" has become a euphemism for often-indifferent, under-funded labor that is done to our bodies to (barely) enable our continued survival. Care is a dirty word in many of our leftist-feminist communities.

Childhood predictors of adult obesity in the Chicago Longitudinal Study.

Despite obesity being a major concern for both children and adults in the United States today, there are few successful childhood interventions that curb obesity later in life. The objective of the current study is to identify childhood predictors of adult obesity at multiple levels in a large longitudinal sample of participants from an economically disadvantaged childhood cohort. 1065 participants (93% Black) from the Chicago Longitudinal Study were interviewed as part of a 30-year follow-up between 2012 and 2017.

Are parent involvement and school quality associated with adult smoking behaviors? Findings from an urban early childhood cohort.

Although smoking prevention is a high priority, few studies have examined alterable family and school context factors in childhood that influence later smoking behaviors. The present study examined associations of parent involvement in and expectations for children's education, elementary school quality, and school mobility with lifetime smoking history in adulthood for a low-income, minority cohort. Participants from the Chicago Longitudinal Study (N = 1142) were interviewed at age 22-24 as part of a 20-year follow-up of a prospective early childhood cohort of economically disadvantaged families.

Cognitive Functioning in Children with Down Syndrome: Current Knowledge and Future Directions.

Infants and children with Down syndrome (DS) can look forward toward bright futures, as individuals with DS are living healthier, more productive lives than ever due to medical advances, opportunities for early and continued intervention, and inclusive education. Despite these advances, infants and children with DS experience challenges in specific domains of cognitive functioning relative to their typically developing (TD) peers. Over the long term, individuals with DS are also more likely to develop Alzheimer's disease relative to the general population.

Sleep Hygiene Mediates, but Does Not Moderate, Associations Between Temperament and Sleep Quality in University Students.

Although there are theoretical reasons to expect associations among temperament, sleep hygiene behaviors (SHB), and global sleep quality (GSQ), these relations have not yet been examined despite their potential impact on undergraduate student well-being. The present study was conducted to (1) examine relations between temperament and GSQ in university students broadly recruited, (2) document associations between SHB and temperament in this sample, and (3) to determine whether associations among temperament, SHB, and GSQ were best explained by mediation or moderation models. One hundred fifty-two university students completed questionnaires that inquired about temperament, SHB, and GSQ.

Say what you mean: rethinking disability language in Adapted Physical Activity Quarterly.

Adapted Physical Activity Quarterly (APAQ) currently mandates that authors use person-first language in their publications. In this viewpoint article, we argue that although this policy is well intentioned, it betrays a very particular cultural and disciplinary approach to disability: one that is inappropriate given the international and multidisciplinary mandate of the journal. Further, we contend that APAQ's current language policy may serve to delimit the range of high-quality articles submitted and to encourage both theoretical inconsistency and the erasure of the ways in which research participants self-identify.

Decreased response to recall antigens is associated with depressed costimulatory receptor expression in septic critically ill patients.

Anti-inflammatory substances are released during septic shock that modulate monocyte function. Decreased monocyte responsiveness to bacterial toxins and decreased expression of human-leukocyte-associated antigen-DR (HLA-DR) have been reported during septic shock and critical illness. Impaired antigen presentation has been inferred from these observations but has not been demonstrated.

Immunization with bacillus Calmette-Guerin vaccine increases aortic atherosclerosis in the cholesterol-fed rabbit.

New Zealand White rabbits were injected subcutaneously with either a human dose of bacillus Calmette Guerin (BCG) vaccine (n = 7) or saline (n = 7). A further half dose of BCG or saline was injected after a further 4 weeks. The animals were subsequently fed a 0.

Monophosphoryl lipid A stimulated up-regulation of nitric oxide synthase and nitric oxide release by human monocytes in vitro.

Monophosphoryl lipid A (MPL) is a derivative of lipopolysaccharide (LPS) with reduced toxicity which has been shown to modulate various immune functions in monocytes. We examined whether human monocytes can be stimulated to produce nitric oxide (NO) and its catalytic enzyme nitric oxide synthase (NOS). Monocytes were stimulated with LPS or MPL and both NOS and NO (as nitrite) production were measured.

Activity of mycobacterial promoters during intracellular and extracellular growth.

pUS933, a bifunctional Mycobacterium-Escherichia coli translational fusion vector containing an amino-terminally truncated E. coli lacZ reporter gene, was constructed. Derivatives of pUS933, containing the promoter, RBS and start codon of the Mycobacterium bovis BCG hsp60 gene, the Mycobacterium leprae 28 kDa gene and the M.

Investigations into the mechanisms of carcinogen-induced nuclear enlargement in HeLa S3 cells in vitro.

Carcinogen-induced nuclear enlargement has been reported both in vitro and in vivo, but the mechanism, and whether it is causally related to carcinogenesis, has not yet been established. This study was designed to investigate the role of increased DNA content, such as might occur in polyploidy, in induction of nuclear enlargement. The effects of two genotoxic carcinogens, N-methyl-N-nitrosourea and adriamycin, were compared with the effects induced by diethylstilboestrol, which is arguably a non-genotoxic carcinogen but is known to induce polyploidy.

Flow cytometric measurement of non-specific esterase activity.

alpha-Naphthyl acetate esterase (alpha-NAE) is primarily found in mononuclear phagocytes and may be used to distinguish them from other leucocytes. Conventional cytochemical techniques are subjective and may be difficult to interpret, especially with cells which express only low levels of activity. This has caused difficulties in the classification of non-lymphoblastic leukaemias.

An association between Gc (vitamin D-binding protein) alleles and susceptibility to rheumatic fever.

Rheumatic fever is associated with exaggerated activity of B cells with massive production of antibody to the Group A streptococcus. Gc (vitamin D-binding protein) is constitutively expressed on B-cell membranes in association with membrane immunoglobulin, and could be involved in cell activation. We therefore looked for associations between the three major Gc alleles and susceptibility to rheumatic fever in a homogeneous Arab population.
