Research Brief: Practical Evidence for Naloxone, Immunization Clinics, and Preparedness
These five recent studies were selected to support Johnson County Health Department’s operational priorities: opioid overdose prevention with naloxone and training, School Health & Immunization Clinics, and all-hazards preparedness including environmental health and health education. Each study offers actionable public health evidence relevant to surveillance, community-facing service delivery, or outbreak response activities your divisions carry out.
Trends in Emergency Department Visits Involving Cannabis Hyperemesis Syndrome Identified Using a New Diagnosis Code – United States, January 2023-May 2026
After introduction of a CHS-specific ICD-10 code in October 2025, reported ED visits for cannabis hyperemesis syndrome rose abruptly and remained elevated, with higher proportions among people aged 15–24 years and females. Authors note the increase likely reflects improved recognition and coding as much as incidence and recommend strengthened education, routine cannabis-use assessment in EDs, and expanded surveillance.
Why it matters for Johnson County Health Department
For Johnson County Health Department this highlights a potentially underrecognized drug-related condition that intersects with substance-use education and overdose-prevention messaging. Nursing and health-education staff running naloxone training or community outreach can incorporate brief guidance on recognizing cannabis-related harms and coordinate with regional EDs and surveillance partners to improve case detection and referral pathways.
Vaccination coverage among individuals receiving HIV pre-exposure prophylaxis (PrEP): A systematic review and meta-analysis
A meta-analysis of 24 studies (13,087 individuals) found suboptimal vaccination coverage among people receiving PrEP: highest for hepatitis B (73%) but lower for monkeypox (61%), hepatitis A (59%), and HPV (43%), with high heterogeneity and frequent self-reported status. The authors identify missed opportunities for delivering recommended vaccines within PrEP care and call for better integration of vaccination into sexual health services.
Why it matters for Johnson County Health Department
Johnson County’s School Health & Immunization Clinics and event-based vaccination activities could address similar missed opportunities by partnering with local sexual health and primary-care providers who prescribe PrEP. Operationally, this supports use of clinic workflows, standing orders, or targeted outreach to improve vaccine offering and documentation among higher-risk adult populations served in the county.
Colorectal Cancer Mortality Following an Organized Fecal Immunochemical Test-Based Screening Program
A 20-year, population-based evaluation from the Basque Country showed biennial FIT-based screening was associated with a sustained decline in colorectal cancer mortality, with a 50% reduction in those aged 50–69 and most screen-detected cancers diagnosed at early stages. Analyses suggested a clear inflection point a few years after program implementation consistent with screening impact.
Why it matters for Johnson County Health Department
This study reinforces that organized, population-level screening programs produce measurable mortality benefits and that sustained participation and follow-up are key. For Johnson County, the finding supports incorporating systematic outreach and reminder strategies into clinic planning, leveraging School Health & Immunization Clinic events to promote age-appropriate preventive screening education, and coordinating with healthcare partners on follow-up pathways.
Outbreak of Hepatitis A Linked to Frozen Blueberries, the Netherlands, 2024-2025
An investigation of 24 hepatitis A cases identified consumption of frozen blueberries from a specific supermarket chain as the likely source after detection of outbreak strain RNA in a food product. The report documents how combined epidemiologic and laboratory evidence enabled product traceback and source identification.
Why it matters for Johnson County Health Department
The environmental health and emergency-response implications are directly relevant to Johnson County’s responsibilities for foodborne outbreak detection and community messaging. This case underscores the value of rapid source traceback, coordination with retailers and state partners, and the potential role of targeted communication or vaccine outreach through your immunization clinics when imported or widely distributed products are implicated.
Outbreak of Salmonella enterica Serovar Reading Linked to Dried Bovine Meat, New South Wales, Australia, 2023
A Salmonella Reading outbreak was traced to dried bovine meat linked to a restaurant and products sold in South Asian grocery stores; isolates matched the product and an unlicensed meat processor was identified as a likely source. The investigation emphasizes the role of supply-chain tracing and regulatory gaps in preventing foodborne illness.
Why it matters for Johnson County Health Department
This investigation offers practical lessons for Johnson County’s environmental and restaurant inspection programs about traceback, inspection of specialty and ethnic food suppliers, and outreach to small processors and retailers. Incorporating these lessons can strengthen local surveillance, targeted food-safety education, and coordination with licensing authorities to reduce similar contamination risks.
Together these studies emphasize two operational priorities: strengthen surveillance and interagency traceback/notification for substance- and food-related events, and integrate prevention (vaccination and screening) into existing clinic and outreach workflows. Applying these lessons can help Johnson County’s nursing, environmental, and health-education divisions align day-to-day services with measurable prevention outcomes.
