RESUMEN

Cervical artery dissection is an uncommon condition for which pregnancy and postpartum states confer increased risk. Although the majority of patients with this condition fully recover, including resolution of the dissection on imaging, long-term sequelae include a variety of cardiovascular conditions that may be associated with high rates of morbidity and mortality. Here, we review 2 cases of vertebral artery dissection in relation to pregnancy. Our first case will review the management of a pregnant patient with a history of vertebral artery dissection; whereas our second case reviews a presentation of postpartum vertebral artery dissection. Providers should maintain a high suspicion of cervical artery dissection in pregnant and postpartum patients presenting with headache and neck pain.

RESUMEN

BACKGROUND: The aim of this study was to determine the extent to which socioeconomic characteristics of the home and neighborhood are associated with racial inequalities in brain outcomes. METHODS: We performed a cross-sectional analysis of the baseline dataset (v.2.0.1) from the Adolescent Brain and Cognitive Development (ABCD) Study. Cognitive performance was assessed using the National Institutes of Health Toolbox (NIH-TB) cognitive battery. Standard socioeconomic indicators of the family and neighborhood were derived from census-related statistics. Cortical morphometric measures included MRI-derived thickness, area, and volume. RESULTS: 9638 children were included. Each NIH-TB cognitive measure was negatively associated with household and neighborhood socioeconomic characteristics. Differences in cognitive scores between Black or Hispanic children and other racial groups were mitigated by higher household income. Most children from lowest-income families or residents in impoverished neighborhoods were Black or Hispanic. These disparities were associated with racial differences in NIH-TB measures and mediated by smaller cortical brain volumes. CONCLUSIONS: Neighborhood socioeconomic characteristics are associated with racial differences in preadolescent brain outcomes and mitigated by greater household income. Household income mediates racial differences more strongly than neighborhood-level socioeconomic indicators in brain outcomes. Highlighting these socioeconomic risks may direct focused policy-based interventions such as allocation of community resources to ensure equitable brain outcomes in children. IMPACT: Neighborhood socioeconomic characteristics are associated with racial differences in preadolescent brain outcomes and mitigated by greater household income. Household income mediates racial differences more strongly than neighborhood-level socioeconomic indicators in brain outcomes. Highlighting these disparities related to socioeconomic risks may direct focused policy-based interventions such as allocation of community resources to ensure equitable brain outcomes in children.

RESUMEN

PROBLEM: Protective effects for adult neurological disorders have been attributed to sex hormones. Using a murine model of prematurity, we evaluated the role of estrogen signaling in the process of perinatal brain injury following exposure to intrauterine inflammation. METHOD OF STUDY: Intrauterine lipopolysaccharide (LPS) was used to invoke preterm labor and fetal neuroinflammation. Fetal brains were analyzed for changes in Esr1, Esr2 and Cyp19. Dams heterozygous for the Esr1 knockout allele were also given intrauterine LPS to compare delivery and offspring viability to wild type controls. RESULTS: The upregulation in inflammatory cytokines was accompanied by an increase in Esr1 and Esr2 transcripts, though protein levels declined. Cyp19 did not differ by mRNA or protein abundance. Offspring from Esr1 mutants were larger, had a longer gestation and significantly greater mortality. CONCLUSIONS: Estrogen signaling is altered in the fetal brains of preterm offspring exposed to neuroinflammatory injury. The reduction of Esr1 and Esr2 proteins with LPS suggests that these proteins are degraded. It is possible that transcriptional upregulation of Esr1 and Esr2 occurs to compensate for the loss of these proteins. Alternatively, the translation of Esr1 and Esr2 mRNAs may be disrupted with LPS while a feedback mechanism upregulates transcription. Intact Esr1 signaling is also associated with early preterm delivery following exposure to intrauterine LPS. A loss of one Esr1 allele delays this process, but appears to do so at the cost of fetal viability. These results suggest estrogen signaling plays opposing roles between maternal and fetal responses to preterm birth.

RESUMEN

Zika virus infection can result in devastating pregnancy outcomes when it crosses the placental barrier. For human pregnancies, the mechanisms of vertical transmission remain enigmatic. Utilizing a human placenta-cotyledon perfusion model, we examined Zika virus exposure in the absence of maternal factors. To distinguish responses related to viral infection vs. recognition, we evaluated cotyledons perfused with either active or inactivated Zika virus. Active Zika virus exposure resulted in infection, cell death and syncytium injury. Pathology corresponded with transcriptional changes related to inflammation and innate immunity. Inactive Zika virus exposure also led to syncytium injury and related changes in gene expression but not cell death. Our observations reveal pathologies and innate immune responses that are dependent on infection or virus placenta interactions independent of productive infection. Importantly, our findings indicate that Zika virus can infect and compromise placentas in the absence of maternal humoral factors that may be protective.

RESUMEN

OBJECTIVE: This pilot study aimed to evaluate the relevance, feasibility, acceptability, and instructional efficacy of the Managing and Adapting Practice (MAP) curriculum for enhancing the teaching of psychotherapy to child and adolescent psychiatry (CAP) fellows. MAP is a system of resources and decision models that supports practitioners in selecting and implementing psychotherapeutic interventions for children and adolescents. The MAP curriculum includes modules to guide education about psychotherapeutic procedures (e.g., behavioral activation) common in evidence-based treatments for an array of childhood problems and to support development of competencies in assessment, treatment planning, and reflective practice. METHODS: Curriculum coding was used to examine the relevance of MAP's core components to the skills articulated in the Accreditation Council for Graduate Medical Education (ACGME) CAP milestones. Feasibility, acceptability, and learning outcomes were examined after delivery of the MAP curriculum to 12 CAP fellows at two sites, with instructional features tailored according to faculty preferences and training program structure. RESULTS: Coding suggested that the MAP curriculum was relevant to 95% of the 21 ACGME CAP training subcompetencies. Feasibility was indicated by the successful delivery of 100% of the planned MAP curriculum across the two sites. Acceptability was supported by positive feedback from the CAP fellows, and psychotherapy knowledge increased significantly. Finally, case review scores (mean±SD=2.21±0.15) showed positive posttraining application of MAP to two patients and exceeded scores achieved by other samples of mental health professionals. CONCLUSIONS: This pilot study demonstrated the potential for the MAP curriculum to support CAP education. MAP's versatility as a curriculum supports broader adoption, with continuing rigorous empirical evaluation.

RESUMEN

Experiencing psychosis-spectrum symptoms is challenging to youth. Among many difficulties, internalized mental health stigma-the internalization of negative stereotypes-can lead to shame and withdrawal. The objective of this study was to better understand the correlates of internalized stigma among a clinical sample of youth with psychosis-spectrum symptoms. Participants (n = 66; 12-25 years old) were referred by community providers in Maryland, United States. Psychosis-spectrum symptoms were measured via the Structured Interview for Psychosis-Risk Syndromes (SIPS); family-functioning was measured via the Family Assessment Device. Interviewers rated participants' social/role functioning via the Global Functioning: Social and Role Scales. Internalized stigma was measured using the Internalized Stigma of Mental Illness (ISMI) total scale and subscales. The sample included 34 individuals at clinical high risk for psychosis, 16 experiencing early psychosis, and 16 help-seeking controls. Regression analyses indicated that unusual beliefs, avolition, role functioning, and lower family-functioning (caregiver-reported) were significantly associated with higher aspects of internalized stigma, controlling for other symptoms and sociodemographics. These models explained 27% of the variance (adjusted R2) in the total ISMI scale and between 15% to 49% of the variance in ISMI-subscales. Among this help-seeking sample, unusual beliefs, avolition, higher role functioning, and lower family-functioning (caregiver-reported) were associated with more internalized stigma. Pending future research with larger samples, therapeutic interventions focused on these factors and their correlates may benefit youth. Future research is needed to determine temporal precedence of these associations. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMEN

Cysteine-rich with epidermal growth factor (EGF)-like domains 2 (CRELD2) is an endoplasmic reticulum (ER)-resident chaperone highly activated under ER stress in conditions such as chondrodysplasias; however, its role in healthy skeletal development is unknown. We show for the first time that cartilage-specific deletion of Creld2 results in disrupted endochondral ossification and short limbed dwarfism, whereas deletion of Creld2 in bone results in osteopenia, with a low bone density and altered trabecular architecture. Our study provides the first evidence that CRELD2 promotes the differentiation and maturation of skeletal cells by modulating noncanonical WNT4 signaling regulated by p38 MAPK. Furthermore, we show that CRELD2 is a novel chaperone for the receptor low-density lipoprotein receptor-related protein 1 (LRP1), promoting its transport to the cell surface, and that LRP1 directly regulates WNT4 expression in chondrocytes through TGF-ß1 signaling. Therefore, our data provide a novel link between an ER-resident chaperone and the essential WNT signaling pathways active during skeletal differentiation that could be applicable in other WNT-responsive tissues. © 2020 American Society for Bone and Mineral Research. © 2020 The Authors.

RESUMEN

Early detection and prevention of psychosis has become an international priority. Much of this work has focused on youth presenting with attenuated symptoms of psychosis-those at Clinical High Risk for psychosis (CHR)-given their elevated probability of developing the full disorder in subsequent years. Individuals at CHR may be prone to exacerbated psychological distress during the COVID-19 pandemic and its subsequent physical isolation measures, due to heightened stress sensitivity and comorbid mental health problems. Telepsychotherapy holds promise for reaching this population, especially during the current COVID-19 outbreak. However, there are limited evidence-based guidelines or interventions for use of telepsychotherapy with this population. In this paper, we review common clinical issues for individuals at CHR and how they might be exacerbated by the COVID-19 pandemic; best practices for treatment and adaptations for telepsychotherapy for individuals at CHR; and highlight real clinical issues that we are currently experiencing in a United States-based specialized CHR clinic as we conduct telepsychotherapy via videoconferencing. We conclude with questions for those in the field to contemplate, as well as potential challenges and benefits in using telepsychotherapy with individuals at CHR and their families.

RESUMEN

The mouse zinc-finger gene Zfp521 (also known as ecotropic viral insertion site 3; Evi3; and ZNF521 in humans) has been identified as a B-cell proto-oncogene, causing leukemia in mice following retroviral insertions in its promoter region that drive Zfp521 over-expression. Furthermore, ZNF521 is expressed in human hematopoietic cells, and translocations between ZNF521 and PAX5 are associated with pediatric acute lymphoblastic leukemia. However, the regulatory factors that control Zfp521 expression directly have not been characterized. Here we demonstrate that the transcription factors SPI1 (PU.1) and HOXC13 synergistically regulate Zfp521 expression, and identify the regions of the Zfp521 promoter required for this transcriptional activity. We also show that SPI1 and HOXC13 activate Zfp521 in a dose-dependent manner. Our data support a role for this regulatory mechanism in vivo, as transgenic mice over-expressing Hoxc13 in the fetal liver show a strong correlation between Hoxc13 expression levels and Zfp521 expression. Overall these experiments provide insights into the regulation of Zfp521 expression in a nononcogenic context. The identification of transcription factors capable of activating Zfp521 provides a foundation for further investigation of the regulatory mechanisms involved in ZFP521-driven cell differentiation processes and diseases linked to Zfp521 mis-expression.

RESUMEN

An estimated 11.6% of the world cigarette market is illicit, representing more than 650 billion cigarettes a year and $40.5 billion in lost revenue. Illicit tobacco trade refers to any practice related to distributing, selling, or buying tobacco products that is prohibited by law, including tax evasion (sale of tobacco products without payment of applicable taxes), counterfeiting, disguising the origin of products, and smuggling. Illicit trade undermines tobacco prevention and control initiatives by increasing the accessibility and affordability of tobacco products, and reduces government tax revenue streams. The World Health Organization (WHO) Protocol to Eliminate Illicit Trade in Tobacco Products, signed by 54 countries, provides tools for addressing illicit trade through a package of regulatory and governing principles. As of May 2015, only eight countries had ratified or acceded to the illicit trade protocol, with an additional 32 needed for it to become international law (i.e., legally binding). Data from multiple international sources were analyzed to evaluate the 10 most commonly used approaches for addressing illicit trade and to summarize differences in implementation across select countries and the European Union (EU). Although the WHO illicit trade protocol defines shared global standards for addressing illicit trade, countries are guided by their own legal and enforcement frameworks, leading to a diversity of approaches employed across countries. Continued adoption of the methods outlined in the WHO illicit trade protocol might improve the global capacity to reduce illicit trade in tobacco products.

RESUMEN

Umbilical cord matrix stem (UCMS) cells that were engineered to express interferon-beta (IFN-beta) were transplanted weekly for three weeks into MDA 231 breast cancer xenografts bearing SCID mice in combination with 5-fluorouracil (5-FU). The UCMS cells were found within lung tumors but not in other tissues. Although both treatments significantly reduced MDA 231 tumor area in the SCID mouse lungs, the combined treatment resulted in a greater reduction in tumor area than by either treatment used alone. These results indicate that a combination treatment of UCMS-IFN-beta cells and 5-FU is a potentially effective therapeutic procedure for breast cancer.
