Predictors of Alcohol Use after Bariatric Surgery

Patients undergoing bariatric surgery are at risk for devloping an alcohol use disorder (AUD). The purpose of this study was to investigate pre-surgical psychosocial risk factors for post-surgical alcohol consumption and hazardous drinking. Participants (N = 567) who underwent bariatric surgery between 2014 and 2017 reported their post-surgical alcohol use. Information was collected from the pre-surgical evaluation including history of alcohol use, psychiatric symptoms, and maladaptive eating behaviors (i.e., binge eating, purging, and emotional eating). Younger age and pre-surgical alcohol use predicted post-surgical alcohol use and hazardous drinking. In addition, higher levels of depressive symptoms and maladaptive eating patterns predicted post-surgical binge drinking. Clinicians conducting pre-surgical psychosocial evaluations should be aware of the multiple risk factors related to post-surgical problematic alcohol use. Future research should evaluate whether preventive interventions for high-risk patients decrease risk for post-surgical alcohol misuse

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 $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ 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

An Investigation of Racial Disparities in Weight Loss Outcomes: Roux-en-Y Gastric Bypass Versus Sleeve Gastrectomy

OBJECTIVE: The current study aimed to test if racial disparities in weight loss outcomes between African American and Caucasian patients who underwent bariatric surgery were due to pre-surgical BMI differences. METHODS: Primary data was collected from pre-surgical evaluations conducted at a midwestern hospital. A retrospective chart review was conducted of 136 patients. Patient age and race, type of procedure, and pre- and 1-year post-surgical BMI were collected. RESULTS: African American patients were less likely to undergo bariatric surgery compared with Caucasian patients. Caucasian patients undergoing Roux-en-Y Gastric Bypass (RYGB) had a greater change in BMI compared with African American patients who underwent RYGB. Significant differences in weight loss outcomes were not found among patients who underwent the sleeve gastrectomy. Race was not related to pre-surgical BMI or procedure type. CONCLUSION: Despite pre-surgical BMI typically being higher among African American patients, this was not found in the current study. Pre-surgical BMI may not explain the racial disparities in weight loss post-bariatric surgery that are found between African American and Caucasian patients. Future studies should consider psychosocial, environmental, and cultural influences on racial disparities

Health Literacy, Health Numeracy, and Cognitive Functioning Among Bariatric Surgery Candidates

Inadequate health literacy or numeracy and probable cognitive impairment influence patients\u27 medical outcomes. The study purpose was to examine the prevalence of inadequate health literacy, inadequate health numeracy, and probable cognitive impairment among bariatric surgery candidates and examine associations with undergoing bariatric surgery. Patients (N = 314) completed measures assessing these constructs during a required pre-surgical psychological evaluation. Approximately 9.6%, 24.2%, and 29.5% of the sample had inadequate health literacy, inadequate health numeracy, and probable cognitive impairment, respectively. In univariate analyses, those with inadequate levels of health literacy, inadequate health numeracy, and probable cognitive impairment were less likely to undergo surgery. In a multivariate model, inadequate health literacy independently predicted a lower likelihood of undergoing bariatric surgery. Findings underscore the importance of assessing these factors
