Arterial Hyperoxemia During Cardiopulmonary Bypass Was Not Associated With Worse Postoperative Pulmonary Function: A Retrospective Cohort Study.

BACKGROUND: Arterial hyperoxemia may cause end-organ damage secondary to the increased formation of free oxygen radicals. The clinical evidence on postoperative lung toxicity from arterial hyperoxemia during cardiopulmonary bypass (CPB) is scarce, and the effect of arterial partial pressure of oxygen (Pa o2 ) during cardiac surgery on lung injury has been underinvestigated. Thus, we aimed to examine the relationship between Pa o2 during CPB and postoperative lung injury. Secondarily, we examined the relationship between Pa o2 and global (lactate), and regional tissue malperfusion (acute kidney injury). We further explored the association with regional tissue malperfusion by examining markers of cardiac (troponin) and liver injury (bilirubin). METHODS: This was a retrospective cohort study including patients who underwent elective cardiac surgeries (coronary artery bypass, valve, aortic, or combined) requiring CPB between April 2015 and December 2021 at a large quaternary medical center. The primary outcome was postoperative lung function defined as the ratio of Pa o2 to fractional inspired oxygen concentration (F io2 ); P/F ratio 6 hours following surgery or before extubation. The association between CPB in-line sample monitor Pa o2 and primary, secondary, and exploratory outcomes was evaluated using linear or logistic regression models adjusting for available baseline confounders. RESULTS: A total of 9141 patients met inclusion and exclusion criteria, and 8429 (92.2%) patients had complete baseline variables available and were included in the analysis. The mean age of the sample was 64 (SD = 13), and 68% were men (n = 6208). The time-weighted average (TWA) of in-line sample monitor Pa o2 during CPB was weakly positively associated with the postoperative P/F ratio. With a 100-unit increase in Pa o2 , the estimated increase in postoperative P/F ratio was 4.61 (95% CI, 0.71-8.50; P = .02). Our secondary analysis showed no significant association between Pa o2 with peak lactate 6 hours post CPB (geometric mean ratio [GMR], 1.01; 98.3% CI, 0.98-1.03; P = .55), average lactate 6 hours post CPB (GMR, 1.00; 98.3% CI, 0.97-1.03; P = .93), or acute kidney injury by Kidney Disease Improving Global Outcomes (KDIGO) criteria (odds ratio, 0.91; 98.3% CI, 0.75-1.10; P = .23). CONCLUSIONS: Our investigation found no clinically significant association between Pa o2 during CPB and postoperative lung function. Similarly, there was no association between Pa o2 during CPB and lactate levels, postoperative renal function, or other exploratory outcomes.

Postanesthesia Care Unit and Anesthetic Management Outcomes Among Patients Undergoing Noncardiac Surgery: Differences by Race and Ethnicity.

PURPOSE: To investigate the association of patient race and ethnicity with postanesthesia care unit (PACU) outcomes in common, noncardiac surgeries requiring general anesthesia. DESIGN: Single tertiary care academic medical center retrospective matched cohort. METHODS: We matched 1:1 1836 adult patients by race and/or ethnicity undergoing common surgeries. We compared racial and ethnic minority populations (62 American Indian, 250 Asian, 315 Black or African American, 281 Hispanic, and 10 Pacific Islander patients) to 918 non-Hispanic White patients. The primary outcomes were: the use of an appropriate number of postoperative nausea and vomiting (PONV) prophylactics; the incidence of PONV; and the use of a propofol infusion as part of the anesthetic (PROP). Secondary outcomes were: the use of opioid-sparing multimodal analgesia, including the use of regional anesthesia for postoperative pain control; the use of any local anesthetic, including the use of liposomal bupivacaine; the duration until readiness for discharge from the PACU; the time between arrival to PACU and first pain score; and the time between the first PACU pain score of ≥4 and administration of an analgesic. Logistic and linear regression were used for relevant outcomes of interest. FINDINGS: Overall, there were no differences in the appropriate number of PONV prophylactics, nor the incidence of PONV between the two groups. There was, however, a decreased use of PROP (OR = 0.80; 95% CI: 0.69, 0.94; P = .005), PACU length of stay was 9.56 minutes longer (95% CI: 2.62, 16.49; P = .007), and time between arrival to PACU and first pain score was 2.30 minutes longer in patients from racial and ethnic minority populations (95% CI: 0.99, 3.61; P = .001). There were no statistically significant differences in the other secondary outcomes. CONCLUSIONS: The rate of appropriate number of PONV prophylactic medications as well as the incidence of PONV were similar in patients from racial and ethnic minority populations compared to non-Hispanic White patients. However, there was a lower use of PROP in racial and ethnic minority patients. It is important to have a health equity lens to identify differences in management that may contribute to disparities within each phase of perioperative care.

Derivation and Validation of Clinical Phenotypes of the Cardiopulmonary Bypass-Induced Inflammatory Response.

BACKGROUND: Precision medicine aims to change treatment from a "one-size-fits-all" approach to customized therapies based on the individual patient. Applying a precision medicine approach to a heterogeneous condition, such as the cardiopulmonary bypass (CPB)-induced inflammatory response, first requires identification of homogeneous subgroups that correlate with biological markers and postoperative outcomes. As a first step, we derived clinical phenotypes of the CPB-induced inflammatory response by identifying patterns in perioperative clinical variables using machine learning and simulation tools. We then evaluated whether these phenotypes were associated with biological response variables and clinical outcomes. METHODS: This single-center, retrospective cohort study used Cleveland Clinic registry data from patients undergoing cardiac surgery with CPB from January 2010 to March 2020. Biomarker data from a subgroup of patients enrolled in a clinical trial were also included. Patients undergoing emergent surgery, off-pump surgery, transplantation, descending thoracoabdominal aortic surgery, and planned ventricular assist device placement were excluded. Preoperative and intraoperative variables of patient baseline characteristics (demographics, comorbidities, and laboratory data) and perioperative data (procedural data, CPB duration, and hemodynamics) were analyzed to derive clinical phenotypes using K-means-based consensus clustering analysis. Proportion of ambiguously clustered was used to assess cluster size and optimal cluster numbers. After clusters were formed, we summarized perioperative profiles, inflammatory biomarkers (eg, interleukin [IL]-6 and IL-8), kidney biomarkers (eg, urine neutrophil gelatinase-associated lipocalin [NGAL] and IL-18), and clinical outcomes (eg, mortality and hospital length of stay). Pairwise standardized difference was reported for all summarized variables. RESULTS: Of 36,865 eligible cardiac surgery cases, 25,613 met inclusion criteria. Cluster analysis derived 3 clinical phenotypes: α, ß, and γ. Phenotype α (n = 6157 [24%]) included older patients with more comorbidities, including heart and kidney failure. Phenotype ß (n = 10,572 [41%]) patients were younger and mostly male. Phenotype γ (n = 8884 [35%]) patients were 58% female and had lower body mass index (BMI). Phenotype α patients had worse outcomes, including longer hospital length of stay (mean = 9 days for α versus 6 for both ß [absolute standardized difference {ASD} = 1.15] and γ [ASD = 1.08]), more kidney failure, and higher mortality. Inflammatory biomarkers (IL-6 and IL-8) and kidney injury biomarkers (urine NGAL and IL-18) were higher with the α phenotype compared to ß and γ immediately after surgery. CONCLUSIONS: Deriving clinical phenotypes that correlate with response biomarkers and outcomes represents an initial step toward a precision medicine approach for the management of CPB-induced inflammatory response and lays the groundwork for future investigation, including an evaluation of the heterogeneity of treatment effect.

Racial Disparities in Compensation Among US Anesthesiologists: Results of a National Survey of Anesthesiologists.

BACKGROUND: A racial compensation disparity among physicians across numerous specialties is well documented and persists after adjustment for age, sex, experience, work hours, productivity, academic rank, and practice structure. This study examined national survey data to determine whether there are racial differences in compensation among anesthesiologists in the United States. METHODS: In 2018, 28,812 active members of the American Society of Anesthesiologists were surveyed to examine compensation among members. Compensation was defined as the amount reported as direct compensation on a W-2, 1099, or K-1, plus all voluntary salary reductions (eg, 401[k], health insurance). Covariates potentially associated with compensation were identified (eg, sex and academic rank) and included in regression models. Racial differences in outcome and model variables were assessed via Wilcoxon rank sum tests and Pearson's χ 2 tests. Covariate adjusted ordinal logistic regression estimated an odds ratio (OR) for the relationship between race and ethnicity and compensation while adjusting for provider and practice characteristics. RESULTS: The final analytical sample consisted of 1952 anesthesiologists (78% non-Hispanic White). The analytic sample represented a higher percentage of White, female, and younger physicians compared to the demographic makeup of anesthesiologists in the United States. When comparing non-Hispanic White anesthesiologists with anesthesiologists from other racial and ethnic minority groups, (ie, American Indian/Alaska Native, Asian, Black, Hispanic, and Native Hawaiian/Pacific Islander), the dependent variable (compensation range) and 6 of the covariates (sex, age, spousal work status, region, practice type, and completed fellowship) had significant differences. In the adjusted model, anesthesiologists from racial and ethnic minority populations had 26% lower odds of being in a higher compensation range compared to White anesthesiologists (OR, 0.74; 95% confidence interval [CI], 0.61-0.91). CONCLUSIONS: Compensation for anesthesiologists showed a significant pay disparity associated with race and ethnicity even after adjusting for provider and practice characteristics. Our study raises concerns that processes, policies, or biases (either implicit or explicit) persist and may impact compensation for anesthesiologists from racial and ethnic minority populations. This disparity in compensation requires actionable solutions and calls for future studies that investigate contributing factors and to validate our findings given the low response rate.

Interventional Pain Physician Burnout During the COVID-19 Pandemic: A Survey from the American Society of Pain and Neuroscience.

PURPOSE OF REVIEW: The study sought to assess the prevalence of physician burnout among interventional pain physicians in 2022. RECENT FINDINGS: Physician burnout is major psychosocial and occupational health issue. Prior to the coronavirus disease of 2019 (COVID-19) pandemic, over 60% of physicians reported emotional exhaustion and burnout. Physician burnout was reported to become more prevalent in multiple medical specialties during the COVID-19 pandemic. An 18-question survey was distributed electronically to all ASPN members (n = 7809) in the summer of 2022 to assess demographics, burnout characteristics (e.g., Have you felt burned out due to COVID?), and strategies to cope with burnout and stress (e.g., reached out for mental health assistance). Members were able to complete the survey once and were unable to make changes to their responses once submitted. Descriptive statistics were used to assess the prevalence and severity of physician burnout within the ASPN community. Chi-square tests were used to examine differences in burnout by provider characteristics (age, gender, years practicing, and practice type) with p-values less than 0.05 indicating statistical significance. There were 7809 ASPN members that received the survey email, 164 of those members completed the survey, a response rate of 2.1%. The majority of respondents were male (74.1%, n = 120), 94% were attending physicians (n = 152), and 26% (n = 43) have been in practice for twenty years or longer. Most respondents expressed having experienced burnout during the COVID pandemic (73.5%, n = 119), 21.6% of the sample reported reduced hours and responsibilities during the pandemic, and 6.2% of surveyed physicians quit or retired due to burnout. Nearly half of responders reported negative impacts to their family and social lives as well as personal physical and mental health. A variety of negative (e.g., changes in diet, smoking/vaping) and positive coping strategies (e.g., exercise and training, spiritual enrichment) were employed in response to stress and burnout; 33.5% felt they should or had reached out for mental health assistance and suicidal ideations were expressed in 6.2% due to burnout. A high percentage of interventional pain physicians continue to experience mental symptoms that may lead to risk for significant issues going forward. Our findings should be interpreted with caution based on the low response rate. Evaluation of burnout should be incorporated into annual assessments given issues of survey fatigue and low survey response rates. Interventions and strategies to address burnout are warranted.

Matters of the Heart: Examining Motivating Factors and Unconscious Bias in the Adult Cardiothoracic Anesthesiology Fellowship.

OBJECTIVES: The purpose of this study was to identify barriers to improving diversity within adult cardiothoracic anesthesiology (ACTA) and to provide possible strategies that could be implemented by evaluating the demographics of current ACTA fellows, examining motivating factors to pursue the sub-specialty, and assessing perceptions of unconscious biases during their application process and training. DESIGN: A survey was created by the authors and distributed electronically by the Society of Cardiovascular Anesthesiologists to the ACTA Fellows from April to June 2022. SETTING: A multicenter survey. PARTICIPANTS: Recent 2021 to 2022 ACTA fellows. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 68 fellows were included in the analytical sample; 37.3% were women, and 58.2% were men. Half of the participants in the sample were White race (47%), 26% were Asian, 8% Hispanic or Latinx, 5% Black, and 2% were Pacific Islander or Native Hawaiian. Most fellows indicated that the complexity of cases and/or competency in transesophageal echocardiography was "very important" in their motivating factor (74.0%). When examining sex differences, female fellows reported (p value <0.05) that their experience was impacted negatively by sex and was more often treated with less respect and courtesy. There were no statistically significant differences in perceived discrimination by race and/or ethnicity. CONCLUSIONS: This study identified several motivators to pursue ACTA and the perceptions of unconscious biases during the fellowship. Female fellows felt unconscious bias and a negative impact against them due to sex. Due to the small number of undergraduate enrollments, the results should be interpreted cautiously. Additionally, this provides support to complete further studies. Implicit bias training is one strategy that can be implemented to decrease unconscious bias experienced by ACTA fellows.

Residential mobility, neighborhood cohesion, and depressive symptoms among urban-dwelling African American adolescents.

Mechanisms linking residential mobility and depressive symptoms among urban-dwelling African American adolescents have received little attention. This study examined neighborhood cohesion as a possible mechanism. Participants were 358 urban-dwelling African American adolescents (Mage = 14.78; SD = 0.34) who reported their neighborhood cohesion in Grade 10 and depressive symptoms in Grades 9 and 11, and for whom residential address information was available. There was a significant indirect effect of past moves in middle school on depressive symptoms 1 year later through reduced neighborhood cohesion. However, the indirect effect was not significant in a propensity score-matched sample. Results from the full sample of adolescents suggest that neighborhood cohesion may play a role in the experience of depressive symptoms following past moves in middle school. Different findings for the propensity score-matched sample highlight the need for future studies of residential mobility to employ strategies to correct for possible selection bias.

Health Data Disparities in Opioid-Involved Overdose Deaths From 1999 to 2018 in the United States.

Objectives. To examine temporal trends in the classification of opioid-involved overdose deaths (OODs) and racial variation in the classification of specific types of opioids used. Methods. We analyzed OODs coded as other or unspecified narcotics from 1999 to 2018 in the United States using data from the National Vital Statistics System and the Centers for Disease Control and Prevention. Results. The total proportion of OODs from unspecified narcotics decreased from 32.4% in 1999 to 1.9% in 2018. The proportion of OODs from unspecified narcotics among African American persons was approximately 2-fold greater than that of non-Hispanic White persons until 2012. Similarly, the proportion of OODs from unspecified narcotics among Hispanic persons was greater than that of White persons until 2015. After we controlled for death investigation system, African American persons had a higher incidence rate of OODs from unspecified narcotics compared with White persons. Conclusions. There have been significant improvements in the specification OODs over the past 20 years, and there has been significant racial disparity in the classification of OODs until about 2015. The findings suggest a health data disparity; the excessive misclassification of OODs is likely attributable to the race/ethnicity of the decedent.

Comparing the Mutual Interchangeability of ECOM, FloTrac/Vigileo, 3D-TEE, and ITD-PAC Cardiac Output Measuring Systems in Coronary Artery Bypass Grafting.

OBJECTIVE: The aim of this study was to compare the mutual interchangeability of 4 cardiac output measuring devices by comparing their accuracy, precision, and trending ability. DESIGN: A single-center prospective observational study. DESIGN: Nonuniversity teaching hospital, single center. PARTICIPANTS: Forty-four consecutive patients scheduled for elective, nonemergent coronary artery bypass grafting (CABG). INTERVENTIONS: The cardiac output was measured for each participant using 4 methods: intermittent thermodilution via pulmonary artery catheter (ITD-PAC), Endotracheal Cardiac Output Monitor (ECOM), FloTrac/Vigileo System (FLOTRAC), and 3-dimensional transesophageal echocardiography (3D-TEE). MEASUREMENTS AND MAIN RESULTS: Measurements were performed simultaneously at 5 time points: presternotomy, poststernotomy, before cardiopulmonary bypass, after cardiopulmonary bypass, and after sternal closure. A series of statistical and comparison analyses including ANOVA, Pearson correlation, Bland-Altman plots, quadrant plots, and polar plots were performed, and inherent precision for each method and percent errors for mutual interchangeability were calculated. For the 6 two-by-two comparisons of the methods, the Pearson correlation coefficients (r), the percentage errors (% error), and concordance ratios (CR) were as follows: ECOM_versus_ITD-PAC (r = 0.611, % error = 53%, CR = 75%); FLOTRAC_versus_ITD-PAC (r = 0.676, % error = 49%, CR = 77%); 3D-TEE versus ITD-PAC (r = 0.538, % error = 64%, CR = 67%); FLOTRAC_versus_ECOM (r = 0.627, % error = 51%, CR = 75%); 3D-TEE_versus ECOM (r = 0.423, % error = 70%, CR = 60%), and 3D-TEE_versus_FLOTRAC (r = 0.602, % error = 59%, CR = 61%). CONCLUSIONS: Based on the recommended statistical measures of interchangeability, ECOM, FLOTRAC, and 3D-TEE are not interchangeable with each other or to the reference standard invasive ITD-PAC method in patients undergoing nonemergent cardiac bypass surgery. Despite the negative result in this study and the majority of previous studies, these less-invasive methods of CO have continued to be used in the hemodynamic management of patients. Each device has its own distinct technical features and inherent limitations; it is clear that no single device can be used universally for all patients. Therefore, different methods or devices should be chosen based on individual patient conditions, including the degree of invasiveness, measurement performance, and the ability to provide real-time, continuous CO readings.

Using Zoning as a Public Health Tool to Reduce Alcohol Outlet Oversaturation, Promote Compliance, and Guide Future Enforcement: a Preliminary Analysis of Transform Baltimore.

Alcohol outlet oversaturation often exacerbates negative public health outcomes. Recently, Baltimore City passed an extensive zoning rewrite ("TransForm Baltimore") that sought to give local government and residents a tool to reduce alcohol outlet oversaturation through land use regulation. The present investigation evaluated the outlet and neighborhood characteristics of stores impacted by two components of TransForm Baltimore: (1) a requirement that taverns licensed for on-premise consumption in addition to off-premise, carryout sales generate at least 50% of their business from on-premise sales, and (2) a requirement to close, repurpose, or relocate all package stores (i.e., off-premise alcohol outlets) that have been operating as "non-conforming" in residential zones since 1971. Research assistants visited every off-premise alcohol outlet in the city (n = 685) to complete an observational assessment. Approximately 77% (n = 530) of these off-premise alcohol outlets were open, including 292 taverns and 238 package stores. t tests and chi-square tests were used to compare neighborhood characteristics (neighborhood disadvantage, median household income, and racial segregation) of sham taverns (i.e., taverns with less than 50% space dedicated for on-premise sales that were primarily operating as a package store) and non-conforming package stores. Of the 292 taverns accessible during the study, the remainder were chronically closed (n = 130); 24 (8.2%) were deemed sham taverns. Sham taverns were more likely to be located in communities with more economic disadvantage and lower median household income (t test; p < 0.05). Compared to taverns, a lower proportion of sham taverns had visible dance floor space, patrons drinking, and menus available (chi-square test; p < 0.001). There were 80 residentially zoned, non-conforming alcohol outlets. These non-conforming alcohol outlets were disproportionately distributed in predominately poor and African American communities (t test; p < 0.05). As compared to conforming alcohol outlets, more non-conforming alcohol outlets sold sex paraphernalia and healthy foods (chi-square test; p < 0.05). With active enforcement, TransForm Baltimore offers the opportunity for local government and residents to improve public health and increase health equity in vulnerable and marginalized neighborhoods.

Polygenic and environmental influences on the course of African Americans' alcohol use from early adolescence through young adulthood.

The study examined (a) whether alcohol use subgroups could be identified among African Americans assessed from adolescence through early adulthood, and (b) whether subgroup membership was associated with the interaction between internalizing symptoms and antisocial behavior polygenic risk scores (PRSs) and environmental characteristics (i.e., parental monitoring, community disadvantage). Participants (N = 436) were initially recruited for an elementary school-based prevention trial in a Mid-Atlantic city. Youths reported on the frequency of their past year alcohol use from ages 14-26. DNA was obtained from participants at age 21. Internalizing symptoms and antisocial behavior PRSs were created based on a genome-wide association study (GWAS) conducted by Benke et al. (2014) and Tielbeek et al. (2017), respectively. Parental monitoring and community disadvantage were assessed at age 12. Four classes of past year alcohol use were identified: (a) early-onset, increasing; (b) late-onset, moderate use; (c) low steady; and (d) early-onset, decreasing. In high community disadvantaged settings, participants with a higher internalizing symptoms PRS were more likely to be in the early-onset, decreasing class than the low steady class. When exposed to elevated community disadvantage, participants with a higher antisocial behavior PRS were more likely to be in the early-onset, increasing class than the early-onset, decreasing and late-onset, moderate use classes.

Preparing Students for Success: Differential Outcomes by Preschool Experience in Baltimore City, Maryland.

An early adopter of public preschool (i.e., pre-kindergarten, "pre-k"), evidence from Baltimore City, Maryland, can provide insight for those working to improve access to early education opportunities. We followed a cohort of children entering kindergarten in Baltimore City Public Schools during the 2007-2008 year through the 2010-2011 academic year. Students were grouped by pre-k experience: public pre-k (n = 2828), Head Start (n = 839), Head Start plus public pre-k (n = 247), private pre-k (n = 993), or informal care (n = 975). After adjusting for individual- and school-level characteristics, students from the Head Start plus public pre-k group were the most likely to enter kindergarten with the foundational skills and behaviors needed to be successful (vs. all groups, P ≤ .001). Students in informal care were the least likely to enter kindergarten with this skillset (vs. all pre-k groups P ≤ .001). Children from informal care were also significantly more likely than all other groups to be chronically absent in kindergarten (P ≤ .001). By third grade, children from informal care were least likely to be reading on grade level and most likely to have been retained a grade (vs. all pre-k groups P ≤ .001). Children from disadvantaged populations who were not enrolled in pre-k faced significant difficulties keeping up with their peers throughout elementary school; interventions to improve their transition to school and increase their likelihood of academic success are warranted. Universal preschool is likely to improve education outcomes for children in urban areas.

Expanding Tools for Investigating Neighborhood Indicators of Drug Use and Violence: Validation of the NIfETy for Virtual Street Observation.

A growing body of evidence suggests that characteristics of the neighborhood environment in urban areas significantly impact risk for drug use behavior and exposure to violent crime. Identifying areas of community need, prioritizing planning projects, and developing strategies for community improvement require inexpensive, easy to use, evidence-based tools to assess neighborhood disorder that can be used for a variety of research, urban planning, and community needs with an environmental justice frame. This study describes validation of the Neighborhood Inventory for Environmental Typology (NIfETy), a neighborhood environmental observational assessment tool designed to assess characteristics of the neighborhood environment related to violence, alcohol, and other drugs, for use with Google Street View (GSV). GSV data collection took place on a random sample of 350 blocks located throughout Baltimore City, Maryland, which had previously been assessed through in-person data collection. Inter-rater reliability metrics were strong for the majority of items (ICC ≥ 0.7), and items were highly correlated with in-person observations (r ≥ 0.6). Exploratory factor analysis and constrained factor analysis resulted in one, 14-item disorder scale with high internal consistency (alpha = 0.825) and acceptable fit indices (CFI = 0.982; RMSEA = 0.051). We further validated this disorder scale against locations of violent crimes, and we found that disorder score was significantly and positively associated with neighborhood crime (IRR = 1.221, 95% CI = (1.157, 1.288), p < 0.001). The NIfETy provides a valid, economical, and efficient tool for assessing modifiable neighborhood risk factors for drug use and violence prevention that can be employed for a variety of research, urban planning, and community needs.

Discrepancies in Local, State, and National Alcohol Outlet Listings: Implications for Research and Interventions.

BACKGROUND: The availability of local, state, and national data on alcohol outlet density have important implications for policies and interventions aiming to reduce alcohol-related problems. High-quality data on locations of alcohol outlets is important to accurately inform community interventions and public health initiatives, but such data is often not maintained, readily available, or of sufficient quality. Objectives: This study aims to examine the discrepancies between alcohol outlet databases and how neighborhood characteristics (i.e. income, majority racial population, urbanicity) are associated with the discrepancies between databases. Methods: Data was collected from national (n = 1), local (n = 2), and state databases (n = 3). Negative binomial regression models were used to assess discrepancies in alcohol outlet count at the ZIP code level based on the data source. Results: The average density of alcohol outlets (per 1000 residents) ranged from 0.71 to 2.17 in Maryland, 1.65 to 5.17 in Wisconsin, and 1.09 to 1.22 in Oregon based on different sources of data. Findings suggest high income areas (>200% poverty level) have fewer discrepancies (IR = 0.775, p < 0.01), low income areas (below poverty level) have greater discrepancies (IR = 4.990, p < 0.01), and urban areas tend to have fewer discrepancies (IR = 0.378, p < 0.01) between datasets. Conclusion: Interventions and policies depend on valid and reliable data; researchers, policymakers, and local agencies need to collaborate to develop methods to maintain accurate and accessible data.

Measurement of Social Processes at the Neighborhood Level in Baltimore City.

Small-area ecological research is critical to inform place-based interventions at the neighborhood level; however, objective measurement of the social context has been limited. The current study extends the application of the Neighborhood Inventory for Environmental Typology (NIfETy) through the development and evaluation of measures of social context for a longer period of observation (3 years) and at a larger area of aggregation (census tract clusters) compared to previous studies using measures at the block-face level from a single observation. Observations from the 172-item inventory were collected from a random sample of block faces (n = 793) in Baltimore City annually over a three-year period. Through a multistep process including replication of previous measures, data reduction, and factor analysis, six unique neighborhood-level indices were generated to describe the environmental context: drug and alcohol use, violence, physical disorder, epicenter, youth activity, and improvements. An assessment of measurement consistency and validity provided support for some indices, while others had notable limitations. These indices can assist local policymakers and public health practitioners assessing the needs of individual neighborhoods and evaluating the effectiveness of place-based interventions designed to improve the neighborhood environment and population health outcomes.

Individual and Neighborhood Factors Associated With Sexual Behavior Classes in an Urban Longitudinal Sample.

BACKGROUND: This study aimed to increase understanding of the clustering of sexual behaviors in an urban sample of emerging adults, and the individual and neighborhood factors associated with sexual behavior patterns to provide insight into reducing the disproportionate burden of poor sexual outcomes among urban African Americans. METHODS: We draw on 2 cohorts of urban, predominantly African American youth first assessed at age 6 years and follow-up to emerging adulthood (mean age, 20 years; n = 1618). Latent class analyses by gender identified co-occurrence of sexual behavior. RESULTS: We found 3 classes for both males and females: high-risk (13% of males, 15% of females), low-risk (54% of males, 56% of females) and no-risk (33% of males, 29% of females). Membership in the high-risk class was associated with school dropout, a substance use disorder diagnosis, having a criminal arrest, pregnancy, and sexually transmitted diseases for both males and females. High-risk females also had higher rates of depression. Low-risk males and females also had elevated risk of pregnancy and parenthood. Neighborhood factors distinguished the high- and no-risk classes for males and females, including the neighborhood environment scale, which assessed poverty, safety, drug activity, and crime/violence in the neighborhood. Neighborhood religiosity was inversely associated with membership in the high-risk class compared with the no-risk class for females only. Neighborhood racism distinguished those in the high-risk class compared with the no-risk class for males. CONCLUSIONS: Future work should take into account the clustering of sexual risk behaviors. Specific neighborhood factors could be addressed to reduce sexual health disparities.
