Assessment of Truck-Mounted Area-Wide S-methoprene Applications to Manage West Nile Virus Vector Species in the Suburbs of Chicago, IL, USA.

West Nile virus remains the leading cause of arboviral neuroinvasive disease in the United States, despite extensive efforts to control the mosquito vectors involved in transmission. In this study, we evaluated the effectiveness of Altosid SR-20 (active ingredient, S-methoprene 20%) larvicide applications using truck-mounted ultra-low volume (ULV) dispersal equipment to target Culex pipiens Linnaeus (Diptera: Culicidae) and Cx. restuans (Theobald)larvae. A combination of emergence bioassays, open-field measurements of deposited S-methoprene and spray distribution using gas chromatography-mass

Polysubstance use in a community sample of Black cisgender sexual minority men and transgender women in Chicago during initial COVID-19 pandemic peak.

BACKGROUND: In response to COVID-19, the city of Chicago issued stay-at-home orders, which began on March 20, 2020, and restrictions meant to "flatten the curve" remained in effect until June 2, 2020. On June 3, 2020, Chicago entered the reopening phase. This study compares rates of polysubstance use by COVID-19 lockdown phase and across sociodemographic characteristics in a Chicago-based sample of Black cisgender sexual minority men (SMM) and transgender women. METHOD: Data come from the Neighborhood and Networks (N2) cohort, an ongoing study of Black cisgender SMM and transgender women livi…

Multi-Year Comparison of Community- and Species-Level West Nile Virus Antibody Prevalence in Birds from Atlanta, Georgia and Chicago, Illinois, 2005-2016.

West Nile virus (WNV) is prevalent in the United States but shows considerable variation in transmission intensity. The purpose of this study was to compare patterns of WNV seroprevalence in avian communities sampled in Atlanta, Georgia and Chicago, Illinois during a 12-year period (Atlanta 2010-2016; Chicago 2005-2012) to reveal regional patterns of zoonotic activity of WNV. WNV antibodies were measured in wild bird sera using ELISA and serum neutralization methods, and seroprevalence among species, year, and location of sampling within each city were compared using binomial-distributed gener…

Sexual Positioning Practices and Anal Human Papillomavirus Infection Among Young Men Who Have Sex with Men and Transgender Women-Chicago, Illinois, 2016-2018.

BACKGROUND: Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States; men who have sex with men (MSM) have higher prevalence of infection and related disease compared with other men. We assessed whether differences in HPV acquisition exist among MSM according to their sexual positioning practices, as well as self-reported receipt of HPV vaccination. METHODS: We enrolled young MSM and transgender women aged 18 to 26 years in Chicago, IL (N = 666). Participants self-reported their history of HPV vaccination and submitted self-collected anal swab specimen…

Organ weights and length anthropometry measures at autopsy for sudden infant death syndrome cases and other infant deaths in the Chicago infant mortality study.

Organ weights are a possible diagnostic or pathophysiological clue to distinguishing sudden infant death syndrome (SIDS) cases from other infant deaths but suffer from major confounding. Using autopsy data from the Chicago Infant Mortality Study, a majority African-American case-control study of deceased infants under 1 year conducted 1993-96, we assessed differences in the weights of brain, thymus, kidneys, lungs, liver, spleen, total body, and four length anthropometry measures in SIDS-diagnosed infants compared to controls. Using exact and coarsened matching, we ran Bayesian linear models w…

Changes in the Treatment of Primary Esophageal Motility Disorders Imposed by the New Classification for Esophageal Motility Disorders on High Resolution Manometry (Chicago Classification 4.0).

The Chicago Classification is the most used classification for primary esophageal motility disorders (PEMD). This classification was recently updated to the 4.0 version. This opinion piece focuses on the possible implications for the treatment of PMED determined by the new classification. Chicago Classification 4.0 included two new concepts for the diagnosis of achalasia: (1) type III achalasia diagnosis demands 100% absent peristalsis defined as either failed peristalsis or spasm; (2) "inconclusive diagnosis of achalasia" was added as a possibility. Both may decrease unnecessary treatment. Es…

A population-based study of physical function and risk for elder abuse reported to social service agency: findings from the Chicago health and aging project.

We examined the association between physical function and the risk for reported elder abuse. In the Chicago Health and Aging Project (N = 8,932), 238 participants had reported elder abuse. The independent variable was objectively assessed physical function using both directly observed physical performance testing and self-reported physical function (Katz activity of daily living scale, Nagi physical activity scale, and Rosow Breslau mobility scales). Outcomes were elder abuse and specific subtypes of elder abuse. After adjusting for confounders, lower levels of physical performance testing (OR…

A Disconnect Between Operational Evaluations of Larvicide Treatments to Storm Sewer Catch Basins and Findings of Larvicide Resistance in the Northwest Suburbs of Chicago, IL, USA.

Regular evaluations of larvicide resistance and operational control effectiveness are two basic components of the Integrated Mosquito Management approach. It is therefore important for mosquito control programs to assess both the efficacy and the effectiveness of larvicide treatments. Recent observations in 2023 and 2024 within areas served by the Northwest Mosquito Abatement District (NWMAD) indicated that methoprene resistance categorized as high and extreme exist in populations of Culex pipiens (L). Despite more than 20 years of exclusive use of Altosid® XR (2.1% methoprene) larvicide in NW

Prospective associations of interleukin-6 and APOE allele with cognitive decline in biracial community-dwelling older adults: The Chicago Health and Aging Project (CHAP).

INTRODUCTION: It is unclear whether inflammation, that is, high interleukin-6 (IL-6) levels, and genetic risk, that is, apolipoprotein E (APOE) ε4 allele, have a compounding effect on cognitive decline (CD). METHODS: We analyzed a subset of participants from the longitudinal cohort study, Chicago Health and Aging Project, comprising 1120 biracial community-dwelling older adults (60% Black and 62% women), and mean follow-up = 6.4 years. We ran adjusted mixed-effects models on2 longitudinal CD. RESULTS: In APOE ε4 carriers, higher serum IL-6 was not associated with the rate of CD (β = -0.0091 …

The "Sweet Spot" Revisited: Optimal Recall Rates for Cancer Detection With 2D and 3D Digital Screening Mammography in the Metro Chicago Breast Cancer Registry.

OBJECTIVE. One central question pertaining to mammography quality relates to discerning the optimal recall rate to maximize cancer detection while minimizing unnecessary downstream diagnostic imaging and breast biopsies. We examined the trade-offs for higher recall rates in terms of biopsy recommendations and cancer detection in a single large health care organization. MATERIALS AND METHODS. We included 2D analog, 2D digital, and 3D digital (tomosynthesis) screening mammography examinations among women 40-79 years old performed between January 1, 2005, and December 31, 2017, with cancer follow

Posttraumatic Stress, Academic Performance, and Future Orientation as Pathways to Community Violence Exposure and Sexual Risk among African American Youth in Chicago's Southside.

Posttraumatic stress, low academic performance, and future orientation as pathways from community violence exposure to sexual risk-taking behavior were examined among 753 African American youth in a large urban school district, ranging from ages of 13 to 24 years. Youth completed a self-report instrument. Youth completed a self-report instrument of Exposure to Violence Probe, University of California at Los Angeles' PTSD Reaction Index Adolescent Version, and Coopersmith's Self-Esteem Scale. Structural equation modeling was performed to examine relationships among the major study variables. Re

Cardiovascular health in young and middle adulthood and medical care utilization and costs at older age - The Chicago Heart Association Detection Project Industry (CHA).

It is unclear how long-term medical utilization and costs from diverse care settings and their age-related patterns may differ by cardiovascular health (CVH) status earlier in adulthood. We followed 17,195 participants of the Chicago Heart Association Detection Project Industry (1967-1973) with linked Medicare claims (1992 to 2010). Baseline CVH is a composite measure of blood pressure, body mass index, diabetes, cholesterol, and smoking and includes four mutually exclusive strata: all factors were favorable (5.5%), one or more factors were elevated but none high (20.3%), one factor was high (…

Evolving clinical problems with Streptococcus pneumoniae: increasing resistance to antimicrobial agents, and failure of traditional optochin identification in Chicago, Illinois, between 1993 and 1996.

Infections due to multidrug-resistant pneumococci are a growing concern. Through December 1995, over 85% of isolates recovered from our patients in Chicago, Illinois, were fully susceptible to penicillin, and only a rare resistant strain was recovered from blood or cerebrospinal fluid (CSF). In December 1995, we began to observe bloodstream infections due to Streptococcus pneumoniae with penicillin MICs that represented either intermediate or full resistance to penicillin. S. pneumoniae isolated between January 1, 1993, and December 31, 1996, were tested against 11 different antimicrobial agen…

Extended-Spectrum β-Lactamase-Producing Enterobacteriaceae Infections in Children: A Two-Center Case-Case-Control Study of Risk Factors and Outcomes in Chicago, Illinois.

BACKGROUND: Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae infections are an emerging problem in children. We sought to identify risk factors and describe outcomes associated with pediatric ESBL-producing bacterial infections at 2 hospitals in Chicago, IL from 2008 to 2011. METHODS: A case-case-control study of children aged 0-17 years was conducted. Cases of Escherichia coli, Klebsiella, and Proteus spp. ESBL-producing bacterial infections (n = 30) were compared to uninfected controls and in parallel, cases of non-ESBL-producing bacterial infections (n = 30) were compared …

Discordance Between Functional Lumen Imaging Probe and Timed Barium Esophagram in Patients With a Chicago Classification v4.0 Manometric Diagnosis of Esophagogastric Junction Outflow Obstruction.

BACKGROUND: A conclusive diagnosis of esophagogastric junction outflow obstruction (EGJOO) requires confirmation of the manometric diagnosis either by timed barium esophagram (TBE) or functional lumen imaging probe (FLIP). However, the comparative performance of these tests for confirming EGJOO is not well defined. We aimed to assess the rate of agreement between FLIP and TBE in confirming a Chicago Classification version 4.0 (CCv4.0) manometric EGJOO diagnosis. METHODS: We included symptomatic patients with a CCv4.0 EGJOO manometric diagnosis who had confirmatory testing with both FLIP and T…

BACKGROUND: We examined the association of cardiovascular health at younger ages with the proportion of life lived free of morbidity, the cumulative burden of morbidity, and average healthcare costs at older ages. METHODS: The CHA study (Chicago Heart Association Detection Project in Industry) is a longitudinal cohort of employed men and women 18 to 74 years of age at baseline examination in 1967 to 1973. Baseline measurements included blood pressure, cholesterol, diabetes mellitus, body mass index, and smoking. Individuals were classified into 1 of 4 strata of cardiovascular health: favorabl…

Association of esophageal motility disorder symptoms with Chicago classification versions 3.0 and 4.0 using high-resolution esophageal manometry: A single-center experience from Saudi Arabia.

BACKGROUND: Esophageal motility disorders (EMDs) can significantly impact patients' quality of life. The Chicago Classification (CC) was developed as a robust framework to enable clinicians to better understand and classify the nature of motility disorders. Previous studies have primarily focused on the CC version 3.0 (CCv3.0), and data regarding the correlation between symptoms and CC version 4.0 (CCv4.0) in the Saudi Arabian population are lacking. This study aimed to assess the correlation between symptoms and CCv3.0 and CCv4.0 using high-resolution esophageal manometry (HRM) in Saudi Arabi…
