    There is a significant burden of hypertension in the United States, which extends to the large and growing Hispanic/Latino population. Previous literature suggests that psychosocial factors are related to hypertension in Hispanics/Latinos. However, cultural factors unique to this population have been largely understudied in this context. The purpose of the current investigation was to examine the association of hypertension prevalence with social support and simpatía, a Hispanic/Latino cultural value emphasizing social harmony. Cross-sectional data from 5,313 adult Hispanics/Latinos, age 18 to 75 years, representing multiple heritage groups were collected as part of the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study. Contrary to predictions, higher social support was related to higher odds of hypertension prevalence across models (OR = 1.11, 95% CI: 1.02, 1.22). In the final main effects logistic regression model, higher simpatía was related to lower odds of hypertension (OR = .83, 95% CI: .77, .90). Sex modified the link between simpatía and hypertension, with significant effects for men but not women. A 1 SD increase in simpatía was associated with 36% lower odds of hypertension in Hispanic/Latino men. The findings suggest that social support was inversely related with hypertension prevalence and that simpatía may be a protective cultural characteristic in relation to hypertension in the Hispanic/Latino population, but only in men. These results contribute to a growing discourse about the role of Hispanic/Latino cultural values in cardiovascular health

    The Interpersonal Support Evaluation List-12 (ISEL-12; Cohen, Mermelstein, Kamarck, & Hoberman, 1985) is broadly employed as a short-form measure of the traditional ISEL, which measures functional (i.e., perceived) social support. The ISEL-12 can be scored by summing the items to create an overall social support score; three subscale scores representing appraisal, belonging, and tangible social support have also been proposed. Despite extensive use, studies of the psychometric properties of ISEL-12 scores have been limited, particularly among Hispanics/Latinos, the largest and fastest growing ethnic group in the United States. The present study investigated the reliability, and structural and convergent validity of ISEL-12 scores using data from 5,313 Hispanics/Latinos who participated in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary study. Participants completed measures in English or Spanish, and identified their ancestry as Dominican, Central American, Cuban, Mexican, Puerto Rican, or South American. Cronbach’s alphas suggested adequate internal consistency for the total score for all languages and ancestry groups; coefficients for the subscale scores were not acceptable. Confirmatory factor analyses revealed that the one-factor and three-factor models fit the data equally well. Results from multigroup confirmatory factor analyses supported a similar one-factor structure with equivalent response patterns and variances between language groups and ancestry groups. Convergent validity analyses suggested that the total social support score related to scores of social network integration, life engagement, perceived stress, and negative affect (depression, anxiety) in the expected directions. The total score of the ISEL-12 can be recommended for use among Hispanics/Latinos

Objective Valid measures of appearance concern are needed in systemic sclerosis (SSc), a rare, disfiguring autoimmune disease. The Derriford Appearance Scale-24 (DAS-24) assesses appearance-related distress related to visible differences. There is uncertainty regarding its factor structure, possibly due to its scoring method. Design Cross-sectional survey. Setting Participants with SSc were recruited from 27 centres in Canada, the USA and the UK. Participants who self-identified as having visible differences were recruited from community and clinical settings in the UK. Participants Two samples were analysed (n=950 participants with SSc; n=1265 participants with visible differences). Primary and secondary outcome measures The DAS-24 factor structure was evaluated using two scoring methods. Convergent validity was evaluated with measures of social interaction anxiety, depression, fear of negative evaluation, social discomfort and dissatisfaction with appearance. Results When items marked by respondents as not applicable' were scored as 0, per standard DAS-24 scoring, a one-factor model fit poorly; when treated as missing data, the one-factor model fit well. Convergent validity analyses revealed strong correlations that were similar across scoring methods. Conclusions Treating not applicable' responses as missing improved the measurement model, but did not substantively influence practical inferences that can be drawn from DAS-24 scores. Indications of item redundancy and poorly performing items suggest that the DAS-24 could be improved and potentially shortened

    The Science Performance of JWST as Characterized in Commissioning

    This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations. Commissioning has made clear that JWST is fully capable of achieving the discoveries for which it was built. Moreover, almost across the board, the science performance of JWST is better than expected; in most cases, JWST will go deeper faster than expected. The telescope and instrument suite have demonstrated the sensitivity, stability, image quality, and spectral range that are necessary to transform our understanding of the cosmos through observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures; https://iopscience.iop.org/article/10.1088/1538-3873/acb29

    The James Webb Space Telescope Mission

    Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4m4m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5m6.5m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

    Biopsychosocial pathways of pain in patients with systemic sclerosis

    Systemic Sclerosis (SSc) is a rheumatic disease characterized by fibrosis of the skin and internal organs. Patients are at risk for poor quality of life, including significant pain. This dissertation evaluated a biopsychosocial model of pain-related quality of life in SSc. Data from the Genetics versus ENvironment In Scleroderma Outcome Study (GENISOS), a prospective cohort study of patients with SSc were used to test the study aims. Study 1 used baseline data to evaluate the factor structure of the Illness Behavior Questionnaire. Four previously derived solutions were tested but none were sufficiently valid or reliable. Exploratory analysis suggested that there were five factors that were relevant to SSc patients : Symptom Bother, Health Worry, Interpersonal Functioning, Other Life Worries, and Affective Inhibition. These indices were related to fatigue, pain, disability, social support, and mental health but not disease severity. Study 2 utilized baseline data to derive biopsychosocial profiles of SSc patients based on indicators of disease severity, perceived physical health, health worry, mental health, and social support. Three classes, which were distinguished by different trait patterns, were termed Managing, Resilient, and Distressed. Results suggested that the Distressed group, which represented individuals with less severe disease but poor psychosocial functioning had the highest pain and analgesic usage. Study 3 evaluated pain over time with regard to medical, psychological, and social characteristics. Pain generally improved for all patients. Individuals with diffuse disease reported worse initial pain, although both classifications had same rate of change. However, when psychosocial characteristics were added to the model, disease classification was no longer a significant predictor. Individuals with better mental health and perceived physical health reported better pain at disease onset. Change in pain over time was moderated by perceived physical health and social support. Overall, the findings suggest that, even in the context of a disease which is characterized by significant damage of bodily tissue, the overall experience of pain was best explained by psychological and social phenomena. Emotional and social functioning, which are potentially modifiable risk factors, may be important targets for comprehensive pain management in this populatio

    INTRODUCTION/OBJECTIVES The effects of hypnosis on acute pain have been discussed recently, resulting in increased attention in the dental/maxillofacial field offering new perspectives, especially in emergency situations, trauma, or acute inflammatory situations where conventional pharmaceuticals are contraindicated due to allergies or intolerance reactions. DATA To systematically evaluate and assess the effects of hypnosis on acute dental/facial pain relief. Randomized controlled trials, cohort studies, controlled clinical trials, cross-sectional studies, evaluation, and validation studies, following the PRISMA guidelines, of human subjects of all ages were included. SOURCES Five electronic databases (Cochrane, Embase, MEDLINE via PubMed, LILACS, Scopus) were screened for studies published between 1989 - 2021. A NIH quality-assessment-tool was performed. STUDY SELECTION/RESULTS 27 papers have been included and a meta-analysis was performed. Hypnosis has been reported to reduce intraoperative and postoperative pain as well as the use of analgesics in various dental procedures such as tooth extraction. Highly hypnotizable subjects generally respond better to hypnosis. Different hypnosis techniques were used for pain relief and relaxation. The studies show a large heterogeneity. CONCLUSION Although there are only a small number of studies on the subject so far, evidence can be confirmed for the effects of hypnosis on acute pain relief in dental/maxillofacial area. Despite the promising results, further research is needed. CLINICAL SIGNIFICANCE Hypnosis offers a possible alternative to conventional pain medications for acute dental and maxillofacial pain, especially in cases of allergies or contraindications; it can be easily applied by a trained practitioner
