Community-engaged health informatics (CEHI) integrates informatics with community-based participatory public health. Addressing social determinants and population health requires mobilization of health-related resources in communities. We present a framework for evaluating the process and outcomes of a CEHI platform designed to improve connectivity among community health resources. The GetHealthyHeights.org CEHI platform was implemented in an urban low-income community. It was designed to facilitate connectivity among health-related community-based organizations (CBOs). To evaluate the process towards and the achievement of connectivity, a conceptual framework, methodology, and operational measures were defined. A system-level approach, such as social network analysis, is required to capture the community as one dynamic unit. The evaluation framework specifies network connectivity metrics based on a social network survey. A network survey of CBOs (n=35) at baseline demonstrates utility of social network data for characterizing connectivity among community resources. The evaluation framework models how informatics and community resources improve population health.

Background: Dexamethasone has proven life-saving in severe acute respiratory syndrome (SARS) and COVID-19 cases. However, its systemic administration is accompanied by serious side effects. Inhalation delivery of dexamethasone (Dex) faces challenges such as low lung deposition, brief residence in the respiratory tract, and the pulmonary mucus barrier, limiting its clinical use.

Background: The inheritance of the short allele, encoding the serotonin transporter (SERT) in humans, increases susceptibility to neuropsychiatric and metabolic disorders, with aging and female sex further exacerbating these conditions. Both central and peripheral mechanisms of the compromised serotonin (5-HT) system play crucial roles in this context. Previous studies on SERT-deficient (Sert) mice, which model human SERT deficiency, have demonstrated emotional and metabolic disturbances, exacerbated by exposure to a high-fat Western diet (WD).

Diabetes is a chronic lifelong condition that requires consistent self-care and daily lifestyle adjustments. Effective disease management involves regular blood glucose monitoring and ongoing nursing support. Inadequate education and poor self-management are key factors contributing to increased mortality among diabetic individuals.

This study investigates the relationship between SARS-CoV-2 RT-PCR cycle threshold (Ct) values and key COVID-19 transmission and outcome metrics across five years of the pandemic in Jalisco, Mexico. Utilizing a comprehensive time-series analysis, we evaluated weekly median Ct values as proxies for viral load and their temporal associations with positivity rates, reproduction numbers (Rt), hospitalizations, and mortality. Cross-correlation and lagged regression analyses revealed significant lead-lag relationships, with declining Ct values consistently preceding surges in positivity rates and hospitalizations, particularly during the early phases of the pandemic.
