Contextual Deprivation, Race and Ethnicity, and Income in Air Pollution and Cardiovascular Disease.

Importance: Socioeconomically disadvantaged subpopulations are more vulnerable to fine particulate matter (PM2.5) exposure. However, as prior studies focused on individual-level socioeconomic characteristics, how contextual deprivation modifies the association of PM2.5 exposure with cardiovascular health remains unclear. Objective: To assess disparities in PM2.5 exposure association with cardiovascular disease among subpopulations defined by different socioeconomic characteristics. Design, Setting, and Participants: This cohort study used longitudinal data on participants with electronic health records (EHRs) from the All of Us Research Program between calendar years 2016 and 2022. Statistical analysis was performed from September 25, 2023, through February 23, 2024. Exposure: Satellite-derived 5-year mean PM2.5 exposure at the 3-digit zip code level according to participants' residential address. Main Outcome and Measures: Incident myocardial infarction (MI) and stroke were obtained from the EHRs. Stratified Cox proportional hazards regression models were used to estimate the hazard ratio (HR) between PM2.5 exposure and incident MI or stroke. We evaluated subpopulations defined by 3 socioeconomic characteristics: contextual deprivation (less deprived, more deprived), annual household income (≥$50 000, <$50 000), and race and ethnicity (non-Hispanic Black, non-Hispanic White). We calculated the ratio of HRs (RHR) to quantify disparities between these subpopulations. Results: A total of 210 554 participants were analyzed (40% age >60 years; 59.4% female; 16.7% Hispanic, 19.4% Non-Hispanic Black, 56.1% Non-Hispanic White, 7.9% other [American Indian, Asian, more than 1 race and ethnicity]), among whom 954 MI and 1407 stroke cases were identified. Higher PM2.5 levels were associated with higher MI and stroke risks. However, disadvantaged groups (more deprived, income <$50 000 per year, Black race) were more vulnerable to high PM2.5 levels. The disparities were most pronounced between groups defined by contextual deprivation. For instance, increasing PM2.5 from 6 to 10 µg/m3, the HR for stroke was 1.13 (95% CI, 0.85-1.51) in the less-deprived vs 2.57 (95% CI, 2.06-3.21) in the more-deprived cohort; 1.46 (95% CI, 1.07-2.01) in the $50 000 or more per year vs 2.27 (95% CI, 1.73-2.97) in the under $50 000 per year cohort; and 1.70 (95% CI, 1.35-2.16) in White individuals vs 2.76 (95% CI, 1.89-4.02) in Black individuals. The RHR was highest for contextual deprivation (2.27; 95% CI, 1.59-3.24), compared with income (1.55; 95% CI, 1.05-2.29) and race and ethnicity (1.62; 95% CI, 1.02-2.58). Conclusions and Relevance: In this cohort study, while individual race and ethnicity and income remained crucial in the adverse association of PM2.5 with cardiovascular risks, contextual deprivation was a more robust socioeconomic characteristic modifying the association of PM2.5 exposure.

Aortic Annular Enlargement vs Isolated Aortic Valve Replacement in Patients With Matched Annulus.

BACKGROUND: We aimed to determine the effect of aortic annular enlargement on the midterm outcomes of aortic valve replacement surgery by comparing patients with the same-sized (≤23 mm) native aortic annuli. METHODS: From January 2011 to June 2022, 1328 patients underwent isolated aortic valve replacement-1163 without aortic annular enlargement (AVR group) and 165 with aortic annular enlargement (AVR+AAE group). Propensity score matching identified 112 pairs, controlling for native aortic annulus diameter, age, sex, diabetes, chronic lung disease, dialysis, ejection fraction, prior cardiac surgery, indication, hypertension, dyslipidemia, valve type, prior stroke, prior myocardial infarction, and case status. RESULTS: Demographic and preoperative variables were similar, except body surface area was larger in the AVR+AAE group (2.1 m2 vs 1.9 m2). Median native aortic annulus diameter was 23 mm in both groups. Median prosthesis size was 25 in the AVR+AAE group and 23 in the AVR group. The AVR+AAE group had longer cardiopulmonary bypass (143 vs 111 minutes) and cross-clamp (115 vs 82 minutes) times. Incidences of perioperative complications, including operative mortality (1.8% AVR+AAE vs 3.6% AVR) were similar between groups. Survival at 6 years was 98% in the AVR+AAE group and 74% in the AVR group (P = .016). Aortic annular enlargement was an independent protective factor for midterm mortality, with a hazard ratio of 0.19 (P = .006). The rate of moderate/severe patient-prosthesis mismatch was 19% in the AVR+AAE group and 31% in the AVR group (P = .16). CONCLUSIONS: Patients with small native aortic annuli (≤23 mm) undergoing isolated aortic valve replacement may benefit from aortic annular enlargement.

Differing associations of PM2.5 exposure with systolic and diastolic blood pressures across exposure durations in a predominantly non-Hispanic Black cohort.

Environmental health research has suggested that fine particulate matter (PM2.5) exposure can lead to high blood pressures, but it is unclear whether the impacts remain the same for systolic and diastolic blood pressures (SBP and DBP). This study aimed to examine whether the effects of PM2.5 exposure on SBP and DBP differ using data from a predominantly non-Hispanic Black cohort collected between 2013 and 2019 in the US. PM2.5 exposure was assessed based on a satellite-derived model across exposure durations from 1 to 36 months. The average PM2.5 exposure level was between 9.5 and 9.8 µg/m3 from 1 through 36 months. Mixed effects models were used to estimate the association of PM2.5 with SBP, DBP, and related hypertension types, adjusted for potential confounders. A total of 6381 participants were included. PM2.5 exposure was positively associated with both SBP and DBP. The association magnitudes depended on exposure durations. The association with SBP was null at the 1-month duration (ß = 0.05, 95% CI: - 0.23, 0.33), strengthened as duration increased, and plateaued at the 24-month duration (ß = 1.14, 95% CI: 0.54, 1.73). The association with DBP started with ß = 0.29 (95% CI: 0.11, 0.47) at the 1-month duration, and plateaued at the 12-month duration (ß = 1.61, 95% CI: 1.23, 1.99). PM2.5 was associated with isolated diastolic hypertension (12-month duration: odds ratio = 1.20, 95% CI: 1.07, 1.34) and systolic-diastolic hypertension (12-month duration: odds ratio = 1.18, 95% CI: 1.10, 1.26), but not with isolated systolic hypertension. The findings suggest DBP is more sensitive to PM2.5 exposure and support differing effects of PM2.5 exposure on SBP and DBP. As elevation of SBP and DBP differentially predict CVD outcomes, this finding is relevant for prevention and treatment.

The Impact of Bicuspid Aortic Valve on Long-term Outcomes After Bioprosthetic Valve Replacement.

BACKGROUND: There are limited data comparing the outcomes of aortic valve replacement surgery between patients with bicuspid aortic valve (BAV) vs tricuspid aortic valve (TAV) morphology. METHODS: From January 2000 to June 2022, 1122 patients with TAV (n = 562) or BAV (n = 560) underwent surgical aortic valve replacement for aortic stenosis with the same type of bovine pericardial stented bioprosthesis. Propensity score matching identified 350 pairs by matching for age, sex, operative status, chronic lung disease, prior stroke, diabetes, ejection fraction, renal failure on dialysis, coronary artery disease, prior cardiac surgery, and concomitant procedures. The primary end points were long-term survival and reoperation. RESULTS: Perioperative outcomes, including reoperation for bleeding, atrial fibrillation, heart block requiring pacemaker, stroke, need for dialysis, and operative mortality, were similar between the matched groups. Survival at 10 years was 67% (95% CI, 59%-74%) in the BAV group and 54% (95% CI, 46%-61%) in the TAV group (P = .001). BAV valve was a significant protective factor for late mortality, with a hazard ratio of 0.60 (95% CI, 0.45-0.81; P < .001). Risk factors for late mortality included age, chronic lung disease, low ejection fraction, and renal failure on dialysis. Cumulative incidence of aortic valve reintervention at 10 years was similar between the groups at 10% in the BAV group and 4.9% in the TAV group (P = .55). CONCLUSIONS: Patients with BAV likely could not be considered the same as patients with TAV when deciding on the approach of aortic valve intervention.

A Mixed-methods Approach to Understanding Language Interpretation Services in Health Care Settings among Asian American Immigrants from Diverse Ethnic Backgrounds.

BACKGROUND: Asian Americans (AA) face cultural and linguistic barriers to health care access, resulting in poor health outcomes. This study investigates the experiences of AAs using language interpretation services (LIS) in health care settings. METHODS: Using a mixed-methods approach, we conducted a community survey (N=401) and seven focus groups between April and September 2023. We use the Andersen model to understand the experience around LIS for AAs and calculated descriptive statistics for predisposing (i.e., sociodemographic factors and attitudes toward LIS), enabling (i.e., perceived barriers), and need factors (i.e., perceived need for LIS). Focus groups were analyzed using a modified template approach to text analysis. RESULTS: Quantitative and qualitative analyses found that although AAs recognize the benefits and need for LIS, various barriers (e.g., lack of interpreters when booking an appointment) preclude these communities from accessing these services. CONCLUSIONS: Results from this study will help inform interventions that seek to improve LIS within health care systems.

Comparison of the short-term outcomes between Y-incision aortic annular enlargement and traditional aortic annular enlargement techniques.

Background: The short-term efficacy and safety of the Y-incision technique of aortic annular enlargement (AAE) has been established. We aimed to determine how the short-term outcomes of the Y-incision technique compared to traditional AAE techniques. Methods: From February 2011 to June 2022, 380 patients at the University of Michigan Hospital underwent aortic valve replacement (AVR) with AAE using either traditional annular enlargement techniques (Traditional group, n=270), including Nicks [63% (171/270)], Manouguian [34% (91/270)], and others [3% (8/270)], or the Y-incision technique (Y-incision group, n=110). Propensity score matching was performed by controlling for age, sex, body surface area (BSA), hypertension, diabetes, dialysis, chronic lung disease, stroke, prior cardiac surgery, primary indication, operative status, concomitant procedures, and prosthesis type, to generate a balanced cohort of 103 pairs. Results: There were no differences in demographics, comorbidities, primary indications of the operations, or concomitant procedures between the matched groups. The median native aortic annulus diameter, measured in the operating room, was 21 mm for both groups. Median prosthesis size was 23 in the Traditional group, and 27 in the Y-incision group (P<0.001). There were no differences in perioperative complications/outcomes between the matched groups, including operative mortality, which was 3.9% (8/206) overall. Short-term survival was similar between the groups on Kaplan-Meier analysis; one-year survival was 95% in the Traditional group, and 97% in the Y-incision group (P=0.54). The Y-incision group had significantly lower mean aortic valve gradients (7 vs. 10 mmHg, P<0.001), larger aortic valve areas (2.2 vs. 1.8 cm2, P=0.007), and less moderate/severe patient-prosthesis mismatch (PPM) (5.5% vs. 23%, P=0.039) on one-year follow-up echocardiography. Conclusions: The Y-incision technique was as safe and more effective in enlarging the aortic annulus and upsizing the prosthetic valve than the traditional techniques of AAE in AVR for small aortic annuli.

Renal Dysfunction at Discharge and Long-Term Survival in Acute Type A Aortic Dissection.

INTRODUCTION: We aimed to investigate the association between renal dysfunction at discharge and long-term survival in acute type A aortic dissection (ATAAD) patients following surgery. METHODS: From 2000 to 2021, 784 patients underwent aortic repair for an ATAAD. Patients were stratified based on creatinine (Cr) level at discharge alive or dead: normal Cr (n = 582) and elevated Cr defined as >1.3 mg/dL for males and >1.0 mg/dL for females or on dialysis at discharge (n = 202). RESULTS: Preoperatively, both groups had similar rates of comorbidities except for the elevated-Cr group which had more diabetes, chronic obstructive pulmonary disease, and chronic and acute renal insufficiency. Both groups had similar open ATAAD repair procedures. Postoperative outcomes in the elevated-Cr group were significantly worse, including six times higher operative mortality (20% versus 3.4%, P < 0.0001). The landmark long-term survival after discharge alive was significantly worse in the elevated-Cr group than the normal-Cr group (10-y survival: 48% versus 69%, P = 0.0009). The elevated Cr on dialysis at discharge group had significantly worse five-year survival (40%) than the elevated Cr not on dialysis at discharge group (80%, P = 0.02) and the normal-Cr group (87%, P < 0.0001). Additionally, the elevated Cr not on dialysis had a worse five-year survival than the normal-Cr group (80% versus 87%, P = 0.02). Elevated Cr at discharge on dialysis was a significant risk factor for late mortality (hazard ratio = 4.22, 95% confidence interval: [2.07, 8.61], P < 0.0001). CONCLUSIONS: Renal dysfunction at discharge was associated with significantly decreased short-term and long-term survival following open ATAAD repair. Surgeons should aggressively prevent renal dysfunction, especially new-onset dialysis, at discharge as it is correlated with significantly worse short-term and long-term outcomes.

Mixed methods approach to understanding COVID-19 vaccine hesitancy among immigrants in the Chicago.

BACKGROUND: COVID-19 vaccine hesitancy has been particularly high among immigrant populations, whose experience is shaped by a history of racism and discriminations, and distrust of the healthcare system. In this study we draw from the Theory of Planned Behavior to examine COVID-19 vaccine hesitancy among immigrants in Chicago. METHODS: A mixed-methods approach comprising of both focus groups and a health survey was conducted from February to August 2022. Five focus groups were held (N = 35) among Black, Asian and Arab/Palestine participants to understand attitudes and beliefs around the COVID-19 vaccine. Focus groups were analyzed using a modified template approach to text analysis. Based on these findings and themes, we developed a survey that was conducted among 413 immigrants from the mentioned communities. We used hierarchical ordinal regression analyses to examine the relationship between COVID-19 vaccine hesitancy and vaccination status. RESULTS: Qualitative analysis suggest that the major factors influencing COVID-19 vaccine hesitancy included fear of adverse reactions, misinformation around COVID-19 and the vaccine, negative social norms around vaccination, and external pressure to get vaccinated. From our quantitative analysis we found that 24% of participants were unvaccinated, 5% were partially vaccinated, 32.3% were vaccinated but not boosted, and 39% were vaccinated and boosted for COVID-19. Hierarchical regression models suggest that immigrants who hold negative attitudes and social norms around the COVID-19 vaccine are less likely to vaccinate. CONCLUSIONS: Understanding vaccine hesitancy among immigrants allows for the creation of culturally and linguistically tailored education that can be utilized to increase vaccine confidence and uptake.

Acute type A intramural hematoma: The less-deadly acute aortic syndrome?

OBJECTIVE: To evaluate the short- and midterm outcomes of surgically managed acute type A intramural hematoma (IMH) versus classic acute type A aortic dissection (ATAAD). METHODS: From 1996 to February 2023, a total of 106 patients with acute type A IMH and 795 patients with classic ATAAD presented for open aortic repair at our institution. Data were obtained from the local Society of Thoracic Surgeons' Data Warehouse and medical chart review. RESULTS: Compared with the classic ATAAD group, the IMH group was older (65 vs 59 years, P < .001) and more likely to be female (45% vs 32%, P = .005), with fewer comorbidities such as severe aortic insufficiency (5.0% vs 25%, P < .001), acute stroke (2.8% vs 8.3%, P = .05), acute renal failure (5.7% vs 13%, P = .04), and malperfusion syndrome (8.5% vs 26%, P < .001) but more cardiac tamponade (18% vs 11%, P = .03). The IMH group had less aortic root replacement (15% vs 33%, P < .001), zone 2 arch replacements (9.4% vs 18%, P = .02), and shorter crossclamp times (120 minutes vs 150 minutes, P < .001). The operative mortality was significantly lower in the IMH group (0.9% vs 8.8%, P = .005) and a multivariable regression model showed IMH to be protective, odds ratio of 0.11, P = .03. The 10-year survival was similar between the 2 groups (65% vs 61%, P = .35). The hazard ratio of IMH for midterm mortality after surgery was 0.73, P = .12. CONCLUSIONS: Acute type A IMH could be treated with emergency open aortic repair with excellent short- and midterm outcomes.

Smoking behavior among Asian Americans during the initial phase of the COVID-19 pandemic: The influence of pandemic stressors and depression.

INTRODUCTION: Heightened levels of distress among Asian Americans during the initial phases of the pandemic may be associated with current smoking behavior. In this study, we examine differences in current smoking among Asian Americans from two different ethnic backgrounds before and during the COVID-19 pandemic. METHODS: We analyzed cross-sectional survey data (n=202) from Chinese and South Asian adults in Chicago, collected between February and May 2020. We conducted logistic regression models to estimate the relationship between exposure to the COVID-19 pandemic and current smoking. We tested whether the association varied by Asian American ethnic group, unemployment, racial discrimination, and depression symptoms. RESULTS: We found that current smoking increased from 28% to 48% among Asian Americans (i.e. Chinese and South Asians) during the pandemic. We found a statistically significant interaction between the COVID-19 period indicator variable and current smoking by Asian American ethnic groups (p=0.014), such that current smoking was lower for Chinese compared to South Asians before COVID-19, but was comparable for both groups during the pandemic. We also found a statistically significant interaction between the period indicator variable and current smoking by racial discrimination (p=0.047) and depression symptoms (p=0.02). Results from these interactions suggest that Asian Americans who experienced racial discrimination and depression during the pandemic may be more likely to be current smokers compared to their pre-pandemic counterparts. CONCLUSIONS: The findings of the study highlight the need for culturally tailored smoking cessation interventions for Asian American communities that address pandemic-related stressors such as discrimination that may trigger cigarette use.

The Role of Health Insurance Type and Clinic Visit on Hypertension Status Among Multiethnic Chicago Residents.

PURPOSE: To investigate the joint relationship of health insurance and clinic visit with hypertension among underserved populations. DESIGN: Population-based cohort study. SUBJECTS: Data from 1092 participants from the Chicago Multiethnic Prevention and Surveillance Study (COMPASS) between 2013 and 2020 were analyzed. MEASURES: Five health insurance types were included: uninsured, Medicaid, Medicare, private, and other. Clinic visit over past 12 months were retrieved from medical records and categorized into 4 groups: no clinic visit, 1-3 visits, 4-7 visits, >7 visits. ANALYSIS: Inverse-probability weighted logistic regression was used to estimate odds ratios (OR) and 95% confidence interval (CI) for hypertension status according to health insurance and clinic visit. Models were adjusted for individual socio-demographic variables and medical history. RESULTS: The study population was predominantly Black (>85%) of low socioeconomic status. Health insurance was not associated with more clinic visit. Measured hypertension was more frequently found in private insurance (OR = 6.48, 95% CI: 1.92-21.85) compared to the uninsured group, while 1-3 clinic visits were associated with less prevalence (OR = .59, 95% CI: .35-1.00) compared to no clinic visit. These associations remained unchanged when health insurance and clinic visit were adjusted for each other. CONCLUSION: In this study population, private insurance was associated with higher measured hypertension prevalence compared to no insurance. The associations of health insurance and clinic visit were independent of each other.

The Society of Thoracic Surgeons Adult Cardiac Surgery Database: 2023 Update on Procedure Data and Research.

The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database is one of the largest and most comprehensive contemporary clinical databases in use. It now contains >9 million procedures from 1010 participants and 3651 active surgeons. Using audited data collection, it has provided the foundation for multiple risk models, performance metrics, health policy decisions, and a trove of research studies to improve the care of patients in need of cardiac surgical procedures. This annual report provides an update on the current status of the database and summarizes the development of new risk models and the STS Online Risk Calculator. Further, it provides insights into current practice patterns, such as the change in the demographics among patients undergoing aortic valve replacement, the use of minimally invasive techniques for valve and bypass surgery, or the adoption of surgical ablation and left atrial appendage ligation among patients with atrial fibrillation. Lastly, an overview of the research conducted using the STS Adult Cardiac Surgery Database and future directions for the database are provided.

Duration-sensitive association between air pollution exposure and changes in cardiometabolic biomarkers: Evidence from a predominantly African American cohort.

BACKGROUND: Ambient fine particulate matter (PM2.5) exposure has been related to cardiometabolic diseases, but the underlying biological pathways remain unclear at the population level. OBJECTIVE: To investigate the effect of PM2.5 exposure on changes in multiple cardiometabolic biomarkers across different exposure durations. METHOD: Data from a prospective cohort study were analyzed. Ten cardiometabolic biomarkers were measured, including ghrelin, resistin, leptin, C-peptide, creatine kinase myocardial band (CK-MB), monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor alpha (TNF-alpha), N-terminal pro B-type natriuretic peptide (NT-proBNP), troponin, and interleukin-6 (IL-6). PM2.5 levels across exposure durations from 1 to 36 months were assessed. Mixed effect model was used to estimate changes in biomarker levels against 1 µg/m3 increase in PM2.5 level across different exposure durations. RESULTS: Totally, 641 participants were included. The average PM2.5 exposure level was 9 µg/m3. PM2.5 exposure was inversely associated with ghrelin, and positively associated with all other biomarkers. The magnitudes of these associations were duration-sensitive and exhibited a U-shaped or inverted-U-shaped trend. For example, the association of resistin were ß = 0.05 (95% CI: 0.00, 0.09) for 1-month duration, strengthened to ß = 0.27 (95% CI: 0.14, 0.41) for 13-month duration, and weakened to ß = 0.12 (95% CI: -0.03, 0.26) for 24-month duration. Similar patterns were observed for other biomarkers except for CK-MB, of which the association direction switched from negative to positive as the duration increased. Resistin, leptin, MCP-1, TNF-alpha, and troponin had a sensitive exposure duration of nearly 12 months. Ghrelin and C-peptide were more sensitive to longer-term exposure (>18 months), while NT-proBNP and IL-6 were more sensitive to shorter-term exposure (<6 months). CONCLUSION: PM2.5 exposure was associated with elevated levels in cardiometabolic biomarkers related to insulin resistance, inflammation, and heart injury. The magnitudes of these associations depended on the exposure duration. The most sensitive exposure durations of different biomarkers varied.

Air quality and cancer risk in the All of Us Research Program.

INTRODUCTION: The NIH All of Us Research Program has enrolled over 544,000 participants across the US with unprecedented racial/ethnic diversity, offering opportunities to investigate myriad exposures and diseases. This paper aims to investigate the association between PM2.5 exposure and cancer risks. MATERIALS AND METHODS: This work was performed on data from 409,876 All of Us Research Program participants using the All of Us Researcher Workbench. Cancer case ascertainment was performed using data from electronic health records and the self-reported Personal Medical History questionnaire. PM2.5 exposure was retrieved from NASA's Earth Observing System Data and Information Center and assigned using participants' 3-digit zip code prefixes. Multivariate logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI). Generalized additive models (GAMs) were used to investigate non-linear relationships. RESULTS: A total of 33,387 participants and 46,176 prevalent cancer cases were ascertained from participant EHR data, while 20,297 cases were ascertained from self-reported survey data from 18,133 participants; 9,502 cancer cases were captured in both the EHR and survey data. Average PM2.5 level from 2007 to 2016 was 8.90 µg/m3 (min 2.56, max 15.05). In analysis of cancer cases from EHR, an increased odds for breast cancer (OR 1.17, 95% CI 1.09-1.25), endometrial cancer (OR 1.33, 95% CI 1.09-1.62) and ovarian cancer (OR 1.20, 95% CI 1.01-1.42) in the 4th quartile of exposure compared to the 1st. In GAM, higher PM2.5 concentration was associated with increased odds for blood cancer, bone cancer, brain cancer, breast cancer, colon and rectum cancer, endocrine system cancer, lung cancer, pancreatic cancer, prostate cancer, and thyroid cancer. CONCLUSIONS: We found evidence of an association of PM2.5 with breast, ovarian, and endometrial cancers. There is little to no prior evidence in the literature on the impact of PM2.5 on risk of these cancers, warranting further investigation.

Mail-Based Self-Sampling to Complete Colorectal Cancer Screening: Accelerating Colorectal Cancer Screening and Follow-up Through Implementation Science.

Introduction: Leveraging cancer screening tests, such as the fecal immunochemical test (FIT), that allow for self-sampling and postal mail for screening invitations, test delivery, and return can increase participation in colorectal cancer (CRC) screening. The range of approaches that use self-sampling and mail for promoting CRC screening, including use of recommended best practices, has not been widely investigated. Methods: We characterized self-sampling and mail strategies used for implementing CRC screening across a consortium of 8 National Cancer Institute Cancer Moonshot Initiative Accelerating Colorectal Cancer Screening and Follow-up through Implementation Science (ACCSIS) research projects. These projects serve diverse rural, urban, and tribal populations in the US. Results: All 8 ACCSIS projects leveraged self-sampling and mail to promote screening. Strategies included organized mailed FIT outreach with mailed invitations, including FIT kits, reminders, and mailed return (n = 7); organized FIT-DNA outreach with mailed kit return (n = 1); organized on-demand FIT outreach with mailed offers to request a kit for mailed return (n = 1); and opportunistic FIT-DNA with in-clinic offers to be mailed a test for mailed return (n = 2). We found differences in patient identification strategies, outreach delivery approaches, and test return options. We also observed consistent use of Centers for Disease Control and Prevention Summit consensus best practice recommendations by the 7 projects that used mailed FIT outreach. Conclusion: In research projects reaching diverse populations in the US, we observed multiple strategies that leverage self-sampling and mail to promote CRC screening. Mail and self-sampling, including mailed FIT outreach, could be more broadly leveraged to optimize cancer screening.

Lasers for the treatment of eyebrow microblading and cosmetic tattoo pigment: a review of the literature.

We aim to discuss the use of laser for the treatment of eyebrow microblading and cosmetic tattoo complications through a review of the literature. Our research question is whether quality-switched or picosecond laser is superior for the removal of eyebrow tattoos. This structured review was conducted using a PubMed search using the search terms "laser tattoo removal" AND "cosmetic tattoo" AND "eyebrow" with the article type filtered to "case reports," "clinical trial," and "randomized controlled trial" ranging from dates 1994-2023. All case reports or series evaluating the effect of laser on eyebrow cosmetic tattooing pigment were included. We summarize the results of 11 studies evaluating the use of laser for cosmetic tattoo removal, with 129 patients treated specifically for eyebrow pigment. Most studies (8/11) report Fitzpatrick skin type or race. Seven studies utilize quality-switched (QS) neodymium-doped yttrium aluminum garnet (Nd:YAG), alexandrite or ruby, three used picosecond (PS) Nd:YAG or alexandrite, and three used carbon dioxide (CO2) laser. We report laser energy, spot size, and pulse duration, as well as treatment outcomes and adverse events. Historically, methods of pigment removal included dermabrasion, cryosurgery, electrosurgery, radiofrequency, infrared light, intense pulsed light, and surgical excision; however, these methods often led to poor cosmetic outcomes including scarring and further dyspigmentation. QS laser treatments provided superior cosmetic outcomes and thus were considered the gold standard treatment option for pigment removal. However, the advent of PS lasers has challenged this given their increased selectivity, lower fluence requirements, and reduction in surrounding thermal damage. Our review demonstrates that PS Nd:YAG is quicker and more effective that QS Nd:YAG in the treatment of eyebrow tattoos. Additionally, the paradoxical darkening seen with QS lasers is less common with PS lasers. We also demonstrate that CO2 laser may be a helpful adjunct to QS or PS laser. This review focuses on Fitzpatrick skin type and race, providing a unique perspective on the use of laser treatment in skin of color, which often poses an additional treatment challenge.
