Ultrasound Appearance of the Endometrium Post-Radiofrequency Ablation.

OBJECTIVE: To describe the ultrasonographic appearance of the post-ablative endometrium to improve knowledge of its sonographic findings. METHODS: This was an Institutional Review Board approved prospective study of patients who underwent second-generation endometrial ablation from 2016 to 2019 at a single health system. Patients had postoperative transvaginal ultrasounds at 2, 6, and 12 months. Ultrasound reports were analyzed for endometrial thickness, description of the endometrium and myometrium, presence of uterine fibroids, and uterine size. Statistical tests for repeated measures were utilized. RESULTS: There were 68 patients with the average age of 42 (SD 6) years and a BMI of 33 (SD 8). Preoperatively the average endometrial thickness was 10 mm, uterine length was 9.7 cm, and 38.2% had leiomyoma. The average endometrial thickness decreased at each ultrasound: 8.4 mm (SD 3.4), 7.2 mm (SD 3.0), and 5.8 mm (SD 2.5) at 2, 6, and 12 months, respectively. When comparing endometrial thickness postoperatively there was a significant difference at 2 and 12 months (P = .041), and 6 and 12 months (P = .031). There was no change during the postoperative period in the presence of leiomyoma, hyperechoic endometrium, hypoechoic endometrium, heterogeneous endometrium, and cystic endometrium on the ultrasounds. CONCLUSION: After ablation with a second-generation device, the endometrial thickness on ultrasound decreases with time following surgery. Additional studies correlating these findings to clinical outcomes would be useful.

Evaluating Neighborhood-Level Differences in Hair Product Safety by Environmental Working Group Ratings among Retailers in Boston, Massachusetts.

BACKGROUND: Personal care products are a notable source of exposure to endocrine-disrupting chemicals (EDCs). Racial/ethnic differences in the use of hair products containing EDCs are reported, with women and children of color more commonly using hair products that are hormonally active and contain EDCs than other racial/ethnic groups. There is limited research examining the neighborhood-level social and economic factors that may contribute to these reported disparities. OBJECTIVES: We aimed to examine the safety of hair products across sociodemographically diverse neighborhoods in Boston, Massachusetts. METHODS: Eight neighborhoods were identified based on indicators of race/ethnicity and socioeconomic status (SES). We randomly selected 50 stores and collected data on the hair products for sale and their corresponding Environmental Working Group (EWG) Skin Deep hazard score. The association between neighborhood and EWG hazard category (low, moderate, high) was examined using a multinomial logistic regression. RESULTS: A total of 14,019 hair products were identified in the eight neighborhoods. When considering products with EWG hazard scores, Roxbury, a lower income community of color, and Mission Hill, a lower income community, were reported to have a higher percentage of high-hazard hair products in comparison with Beacon Hill [12.2% (163/1,332), 11.4% (65/571) vs. 7.9% (30/382), respectively]. Differences between the safety of hair products were observed, with Roxbury and Mission Hill reporting more than a 2-fold higher risk ratio (RR) of finding hair products with high vs. low EWG scores in comparison with that of Beacon Hill [RR for Roxbury: 2.3, 95% confidence interval (CI): 1.1, 4.6; RR for Mission Hill: 2.3, 95% CI: 1.0, 5.4]. Other neighborhoods were also observed to have an increased RR in comparison with Beacon Hill, however, with 95% CIs that extended beyond the null. DISCUSSION: Retail stores in neighborhoods with a higher percentage of residents of color and lower SES were found to be more likely to sell products with high hazard scores than stores in a higher SES and predominately non-Hispanic White neighborhood. https://doi.org/10.1289/EHP10653.

Perceptions of Environmental Influence and Environmental Information-Seeking Behavior Among People With Asthma and COPD.

Environmental exposures and socioeconomic status (SES) are associated with asthma and chronic obstructive pulmonary disease (COPD) morbidity and mortality. Despite efforts to reduce the impact of environmental exposures through regulation and education, knowledge gaps remain. We sought to understand how adults with asthma and COPD perceive and seek information about environmental factors, and how these responses varied by disease or socioeconomic characteristics. Participants with self-reported asthma or COPD enrolled in a digital platform for respiratory disease self-management, consisting of sensors to track medication use and a companion smartphone app, completed an electronic survey exploring perceptions of environmental factors. Using mixed-method analyses, we evaluated differences in responses by disease (asthma vs. COPD), education (≤ vs. > some college), annual household income (< vs. ≥ $50,000), and mean annual residential air pollutant exposure (> vs. ≤80th percentile). Survey responses from 698 participants [500 asthma (72%) and 198 COPD (28%)] were analyzed. A high percentage of participants perceived that environmental factors could influence their symptoms, including: pollen (93% for asthma vs. 86% for COPD), mold (89 vs. 85%), second-hand smoke (89 vs. 83%), and air pollution (84% for both). Participants reported seeking environmental information daily from an average of three sources, preferring mobile apps and television (TV) programs. Significant differences were identified by disease. Conclusion: Participants with asthma and COPD perceive a relationship between their respiratory symptoms and their environment and regularly seek out environmental information. This information can help inform digital health development for respiratory education and self-management.

The Genetic Links to Anxiety and Depression (GLAD) Study: Online recruitment into the largest recontactable study of depression and anxiety.

BACKGROUND: Anxiety and depression are common, debilitating and costly. These disorders are influenced by multiple risk factors, from genes to psychological vulnerabilities and environmental stressors, but research is hampered by a lack of sufficiently large comprehensive studies. We are recruiting 40,000 individuals with lifetime depression or anxiety and broad assessment of risks to facilitate future research. METHODS: The Genetic Links to Anxiety and Depression (GLAD) Study (www.gladstudy.org.uk) recruits individuals with depression or anxiety into the NIHR Mental Health BioResource. Participants invited to join the study (via media campaigns) provide demographic, environmental and genetic data, and consent for medical record linkage and recontact. RESULTS: Online recruitment was effective; 42,531 participants consented and 27,776 completed the questionnaire by end of July 2019. Participants' questionnaire data identified very high rates of recurrent depression, severe anxiety, and comorbidity. Participants reported high rates of treatment receipt. The age profile of the sample is biased toward young adults, with higher recruitment of females and the more educated, especially at younger ages. DISCUSSION: This paper describes the study methodology and descriptive data for GLAD, which represents a large, recontactable resource that will enable future research into risks, outcomes, and treatment for anxiety and depression.

How the ACA's Health Insurance Expansions Have Affected Out-of-Pocket Cost-Sharing and Spending on Premiums.

One important benefit gained by the millions of Americans with health insurance through the Affordable Care Act (ACA) is protection from high out-of-pocket health spending. While Medicaid unambiguously reduces out-of-pocket premium and medical costs for low-income people, it is less certain that marketplace coverage and other types of insurance purchased to comply with the law's individual mandate also protect from high health spending. Goal: To compare out-of-pocket spending in 2014 to spending in 2013; assess how this spending changed in states where many people enrolled in the marketplaces relative to states where few people enrolled; and project the decline in the percentage of people paying high amounts out-of-pocket. Methods: Linear regression models were used to estimate whether people under age 65 spent above certain thresholds. Key findings and conclusions: The probability of incurring high out-of-pocket costs and premium expenses declined as marketplace enrollment increased. The percentage reductions were greatest among those with incomes between 250 percent and 399 percent of poverty, those who were eligible for premium subsidies, and those who previously were uninsured or had very limited nongroup coverage. These effects appear largely attributable to marketplace enrollment rather than to other ACA provisions or to economic trends.

Influence of injury severity on the rate and magnitude of the T lymphocyte and neuronal response to facial nerve axotomy.

The temporal relationship between severity of peripheral axonal injury and T lymphocyte trafficking to the neuronal cell bodies of origin in the brain has been unclear. We sought to test the hypothesis that greater neuronal death induced by disparate forms of peripheral nerve injury would result in differential patterns of T cell infiltration and duration at the cell bodies of origin in the brain and that these measures would correlate with the magnitude of neuronal death over time and cumulative neuronal loss. To test this hypothesis, we compared the time course of CD3(+) T cell infiltration and neuronal death (assessed by CD11b(+) perineuronal microglial phagocytic clusters) following axonal crush versus axonal resection injuries, two extreme variations of facial nerve axotomy that result in mild versus severe neuronal loss, respectively, in the facial motor nucleus. We also quantified the number of facial motor neurons present at 49 days post-injury to determine whether differences in the levels of neuronal death between nerve crush and resection correlated with differences in cumulative neuronal loss. Between 1 and 7 days post-injury when levels of neuronal death were minimal, we found that the rate of accumulation and magnitude of the T cell response was similar following nerve crush and resection. Differences in the T cell response were apparent by 14 days post-injury when the level of neuronal death following resection was substantially greater than that seen in crush injury. For nerve resection, the peak of neuronal death at 14 days post-resection was followed by a maximal T cell response one week later at 21 days. Differences in the level of neuronal death between the two injuries across the time course tested reflected differences in cumulative neuronal loss at 49 days post-injury. Altogether, these data suggest that the trafficking of T cells to the injured FMN is dependent upon the severity of peripheral nerve injury and associated neuronal death.
