Concordance in parent-child and sibling actigraphy-measured sleep: Evidence among early adolescent twins and primary caregivers.

Study Objectives: Growing evidence suggests concordance between parent and youth sleep. However, no known study has simultaneously examined concordance among siblings' sleep patterns. This study investigated daily and average concordance in (1) parent-youth and (2) sibling actigraphy-measured sleep, as well as the degree to which sibling concordance varied by sleeping arrangements.

Childhood bullying victimization, emotion regulation, rumination, distress tolerance, and depressive symptoms: A cross-national examination among young adults in seven countries.

Existing research suggests a robust association between childhood bullying victimization and depressive symptoms in adulthood, but less is known about potential mediators of this link. Furthermore, there is limited cross-national research evaluating similarities and differences in bullying victimization and its associations with mental health. The current study addressed gaps in the literature by evaluating cognitive and affective responses to stress (i.

Emergent community architecture despite distinct diversity in the global whale shark (Rhincodon typus) epidermal microbiome.

Microbiomes confer beneficial physiological traits to their host, but microbial diversity is inherently variable, challenging the relationship between microbes and their contribution to host health. Here, we compare the diversity and architectural complexity of the epidermal microbiome from 74 individual whale sharks (Rhincodon typus) across five aggregations globally to determine if network properties may be more indicative of the microbiome-host relationship. On the premise that microbes are expected to exhibit biogeographic patterns globally and that distantly related microbial groups can perform similar functions, we hypothesized that microbiome co-occurrence patterns would occur independently of diversity trends and that keystone microbes would vary across locations.

Associations between COVID-19 sleep patterns, depressive symptoms, loneliness, and academic engagement: a latent profile analysis.

The COVID-19 pandemic has had important implications for college students' socioemotional and academic well-being. Sleep problems were common during this time, which may have further impacted well-being. Five hundred and fifty-two college students ( = 19.

Dolichocolon (redundant colon) in a rhesus macaque (Macaca mulatta).

Dolichocolon (redundant colon) is an underdiagnosed cause of severe constipation in humans. The clinical presentation reported here in a rhesus macaque closely resembles that of intestinal adenocarcinoma, the most common neoplasia in macaques. Dolichocolon should be considered in differential diagnosis of macaques with anorexia, weight loss, and constipation.

Burden of chronic cough in the UK: results from the 2018 National Health and Wellness Survey.

Background: Chronic cough, defined as daily cough for at least 8 weeks, negatively affects quality of life and work productivity and increases healthcare resource utilisation. We aimed to determine the prevalence and burden of chronic cough in the UK.

Methods: Study participants were general population respondents to the 2018 UK National Health and Wellness Survey (NHWS).

Postoperative analgesia for upper gastrointestinal surgery: a retrospective cohort analysis.

Background: Thoracic epidural analgesia is commonly used for upper gastrointestinal surgery. Intrathecal morphine is an appealing opioid-sparing non-epidural analgesic option, especially for laparoscopic gastrointestinal surgery.

Methods: Following ethics committee approval, we extracted data from the electronic medical records of patients at Royal North Shore Hospital (Sydney, Australia) that had upper gastrointestinal surgery between November 2015 and October 2020.

Podcasts and videos and slides…oh my!: Traditional vs. nontraditional teaching methods in remote settings.

Introduction: Nontraditional teaching methods are student-centered and motivate students to participate in class activities. Some studies have shown benefit in using various teaching activities; however, data are limited regarding students' perspective and performance after implementation of nontraditional learning strategies. The study compared student preference and performance assessment with traditional and nontraditional presentation methods.

Novel measures of family orientation and childhood self-regulation: A genetically informed twin study.

There is a dearth of research examining the relation between culture and childhood self-regulation in family psychology. Family orientation refers to the emphasis on providing support, respect, and obligation to the family system, and it is important for children's functioning, yet existing literature on related constructs often relies on parent-reported measures. Additionally, twin research has neglected the role of culture in the genetic and environmental contributions to children's self-regulation.

Spelling monosyllabic English words.

We conducted a megastudy to examine the spelling of American English monosyllables with typewritten responses. We related both sublexical and lexical/semantic factors to spelling accuracy and reaction time (RT) for the first keypress and response duration for spelling 1,856 monophonic monosyllables. We found that (a) each of 13 predictor variables was significantly related to performance for at least one measure, (b) orthographic length was unrelated to the first key RT, but did relate to accuracy and response duration, (c) sound-spelling and spelling-sound consistency was related to performance, and in particular, onset consistency related to accuracy and first key RT, but was unrelated to response duration, (d) contextual diversity was consistently related to performance across all measures, and (e) age of acquisition (AoA) was related to all measures, but was related more to the first key RT than response duration.

A zebrafish model of combined saposin deficiency identifies acid sphingomyelinase as a potential therapeutic target.

Sphingolipidoses are a subcategory of lysosomal storage diseases (LSDs) caused by mutations in enzymes of the sphingolipid catabolic pathway. Like many LSDs, neurological involvement in sphingolipidoses leads to early mortality with limited treatment options. Given the role of myelin loss as a major contributor toward LSD-associated neurodegeneration, we investigated the pathways contributing to demyelination in a CRISPR-Cas9-generated zebrafish model of combined saposin (psap) deficiency.

Unmet needs with antipsychotic treatment in schizophrenia and bipolar I disorder: patient perspectives from qualitative focus groups.

Background: Schizophrenia (SZ) and bipolar I disorder (BD-I) are chronic mental health disorders often treated with antipsychotic medications. This qualitative study sought to better understand disease burden and treatment experiences with oral antipsychotic medications in participants living with SZ or BD-I.

Methods: Six 90-min focus groups were conducted with participants diagnosed with SZ or BD-I.

Perioperative transfusion and long-term mortality after cardiac surgery: a meta-analysis.

Objectives: Cardiac surgical procedures are associated with a high incidence of periprocedural blood loss and blood transfusion. Although both may be associated with a range of postoperative complications there is disagreement on the impact of blood transfusion on long-term mortality. This study aims to provide a comprehensive review of the published outcomes of perioperative blood transfusion, examined as a whole and by index procedure.

Stress and diurnal cortisol among Latino/a college students: A multi-risk model approach.

The transition to college is a time of increased opportunity and stress spanning multiple domains. Adolescents who encounter significant stress during this transition may be vulnerable to adverse outcomes due to a "wear and tear" of the hypothalamic pituitary adrenal (HPA) axis. Latino/a students may be particularly at-risk for heightened stress exposure due to experiences of both minority-specific and general life stress.

Defining marine bacterioplankton community assembly rules by contrasting the importance of environmental determinants and biotic interactions.

Bacterioplankton communities govern marine productivity and biogeochemical cycling, yet drivers of bacterioplankton assembly remain unclear. Here, we contrast the relative contribution of deterministic processes (environmental factors and biotic interactions) in driving temporal dynamics of bacterioplankton diversity at three different oceanographic time series locations, spanning 15° of latitude, which are each characterized by different environmental conditions and varying degrees of seasonality. Monthly surface samples (5.

Ethnic-Racial Identity Developmental Trajectories Across the Transition to College.

There is limited longitudinal research examining multiple ethnic-racial identity (ERI) components from adolescence into young adulthood. The current study modeled Latino adolescents' ERI trajectories across the college transition (N = 206; M = 18.10 years, SD = 0.

mutation yields supercompetitive B cells primed for malignant transformation.

Multicellular life requires altruistic cooperation between cells. The adaptive immune system is a notable exception, wherein germinal center B cells compete vigorously for limiting positive selection signals. Studying primary human lymphomas and developing new mouse models, we found that mutations affecting disrupt a critical immune gatekeeper mechanism that strictly limits B cell fitness during antibody affinity maturation.

Smoke-Free Policies and Resident Turnover: An Evaluation in Massachusetts Public Housing From 2009‒2018.

Introduction: Smoke-free policies (SFP) in multi-unit housing are a promising tool for reducing exposure to tobacco smoke among residents. Concerns about increased housing instability due to voluntary or involuntary transitions induced by SFPs have been a primary barrier to greater widespread adoption. The impact of SFP implementation on transitions out of public housing in federally funded public housing authorities in Massachusetts was evaluated.

Hillslope roughness reveals forest sensitivity to extreme winds.

Windthrow, or the uprooting of trees by extreme wind gusts, is a natural forest disturbance that creates microhabitats, turns over soil, alters hydrology, and removes carbon from the above-ground carbon stock. Long recurrence intervals between extreme wind events, however, make direct observations of windthrow rare, challenging our understanding of this important disturbance process. To overcome this difficulty, we present an approach that uses the geomorphic record of hillslope topographic roughness as a proxy for the occurrence of windthrow.

Implementation Activities in Smoke-Free Public Housing: The Massachusetts Experience.

A 2018 rule requiring federally-subsidized public housing authorities (PHAs) in the United States to adopt smoke-free policies (SFPs) has sparked interest in how housing agencies can best implement SFPs. However, to date, there is little quantitative data on the implementation of SFPs in public housing. Massachusetts PHAs were among the pioneers of SFPs in public housing, and many had instituted SFPs voluntarily prior to the federal rule.

Models of Classroom Assessment for Course-Based Research Experiences.

Course-based research pedagogy involves positioning students as contributors to authentic research projects as part of an engaging educational experience that promotes their learning and persistence in science. To develop a model for assessing and grading students engaged in this type of learning experience, the assessment aims and practices of a community of experienced course-based research instructors were collected and analyzed. This approach defines four aims of course-based research assessment - 1) Assessing Laboratory Work and Scientific Thinking; 2) Evaluating Mastery of Concepts, Quantitative Thinking and Skills; 3) Appraising Forms of Scientific Communication; and 4) Metacognition of Learning - along with a set of practices for each aim.

Quantifying exposure to chlorhexidine from decontamination of peripheral intravenous injection ports.

Background: Annually, almost 2 billion peripheral intravenous cannulas (PIVCs) are placed worldwide. In response to concerns of infectious complications, chlorhexidine is increasingly utilised for maintenance decontamination of PIVC injection ports. Concomitantly, the allergenic potential of chlorhexidine exposures has been highlighted by several case reports, implicating it as a trigger when used for this seemingly innocuous process.

The PULSE Diversity Equity and Inclusion (DEI) Rubric: a Tool To Help Assess Departmental DEI Efforts.

In an attempt to redesign science, technology, engineering, and mathematics (STEM) departments to be more inclusive of all student populations, institutions of higher learning are reviewing their programs, policies, and the ways they engage students. The Partnership for Undergraduate Life Sciences Education (PULSE) has been working with STEM departments over the past 10 years to improve the student experience by incorporating evidence-based teaching practices and creating curricula with a deeper focus on conceptual understanding of scientific principles, competencies, and the process of science. PULSE created the PULSE rubrics, a set of five rubrics designed to assist life sciences departments in assessing their implementation of the recommendations of the American Association for the Advancement of Science Vision and Change report in the areas of curriculum, assessment, faculty practice and faculty support, infrastructure, and climate for change.

Genome Sequences of Gordonia Phages GrootJr and NovumRegina.

Two bacteriophages, GrootJr and NovumRegina, were discovered, sequenced, and annotated. These phages were isolated from distinct soil and water samples, respectively, on Gordonia terrae 3612. These phages belong to the CR2 subcluster and are similar in genome size and gene content.

Epidermal Microbiomes of Leopard Sharks () Are Consistent across Captive and Wild Environments.

Characterizations of shark-microbe systems in wild environments have outlined patterns of species-specific microbiomes; however, whether captivity affects these trends has yet to be determined. We used high-throughput shotgun sequencing to assess the epidermal microbiome belonging to leopard sharks (Triakis semifasciata) in captive (Birch Aquarium, La Jolla California born and held permanently in captivity), semi-captive (held in captivity for <1 year in duration and scheduled for release; Scripps Institute of Oceanography, San Diego, CA, USA) and wild environments (Moss Landing and La Jolla, CA, USA). Here, we report captive environments do not drive epidermal microbiome compositions of T.
