Knowledge is currently limited about West Nile virus (WNV) infection and its sequelae among children. Available evidence suggests that when compared with adults, children less than 18 years old can be at high risk for WNV exposure and infection yet manifest a lower risk for WNV-related morbidity and mortality. We detail clinical features of pediatric West Nile-associated neurologic disease (WNND) epidemic cases in Cuyahoga County during 2002. We present a structured review of pediatric and adult WNND cases hospitalized in Cuyahoga County, Ohio. During the epidemic, 5 children were hospitalized with confirmed WNND (estimated incidence = 1.4/100,000 children 5-17 years old at risk). Compared with adults, children had shorter hospitalization (mean, 4.6 versus 12.3 days), fewer neurologic symptoms, better neurologic outcomes, and lower mortality (0% versus 5.3%). Cerebrospinal fluid results were similar. When compared with adults, children had significantly lower rates of WNND. Children are at a decreased risk for severe WNV and less likely to present with neurologic signs or suffer neurologic sequelae.

Drug Overdose Death among Residents of Urban Census Tracts: How Granular Geographical Analyses Uncover Socioenvironmental Correlates in Cuyahoga County, Ohio.

Article Synopsis
- Geostatistical data on drug overdose mortality is often aggregated at larger geographic levels, which can mask significant disparities in urban areas.
- This study focused on Cuyahoga County, Ohio, analyzing drug-related mortality rates at the finer census tract level, revealing that individuals in low-opportunity areas are four times more likely to experience drug-related deaths compared to those in high-opportunity areas.
- The research emphasizes the importance of detailed geographic analysis to uncover variations in drug mortality risk, suggesting that targeting specific communities can enhance public health interventions.
Associations Between Callous-Unemotional (CU) Traits and Emotion Recognition Abilities in School Children: The Influence of Conduct Problems and Age.

Department of Psychology, Louisiana State University, Baton Rouge, LA, USA.
Callous-unemotional (CU) traits are associated with severe conduct problems (CP) in youth. Causal theories for CU traits focus on emotion processing deficits that interfere with empathy development. However, though CU traits are consistently associated with deficits in affective empathy (i.

Article Synopsis
- Current epicardial ablation methods struggle to create deep lesions and can damage nearby structures, motivating the study of a new cryoablation catheter designed to address these issues.
- The study involved ten healthy pigs, where researchers used both surgical and percutaneous approaches to create epicardial lesions while measuring the effectiveness and safety of a low-temperature cryoablation system called HeartPad.
- Results showed that lesion depth increased significantly with longer exposure times, suggesting that the new catheter design may improve ablation outcomes while potentially protecting surrounding tissues.
Neighborhood-Level Disparities in Hypertension Prevalence and Treatment Among Middle-Aged Adults.
JAMA Netw Open
August 2024
Quantitative Health Sciences, Lerner Research Institute, Cleveland Clinic, Cleveland, Ohio.
Importance: Hypertension in middle-aged adults (35-50 years) is associated with poorer health outcomes in late life. Understanding how hypertension varies by race and ethnicity across levels of neighborhood disadvantage may allow for better characterization of persistent disparities.
Objective: To evaluate spatial patterns of hypertension diagnosis and treatment by neighborhood socioeconomic position and racial and ethnic composition.

Background: The 2022-23 US influenza season peaked early in fall 2022.
Methods: Late-season influenza vaccine effectiveness (VE) against outpatient, laboratory-confirmed influenza was calculated among participants of the US Influenza VE Network using a test-negative design.
Results: Of 2561 participants enrolled from December 12, 2022 to April 30, 2023, 91 laboratory-confirmed influenza cases primarily had A(H1N1)pdm09 (6B.
