Little information is available about perceptions of influenza vaccination of parents with healthy children in daycare. Therefore, we systematically explored the relationship between parental risk perception and influenza vaccination in children attending daycare. We distributed a self-administered paper survey to parents of children aged 6-59 months attending licensed daycare centres in Tarrant County, Texas. We used conditional logistic regression with penalized conditional likelihood to estimate odds ratios (ORs) and 95% profile likelihood confidence limits (PL) for parental risk-perception factors and influenza vaccination. A high level of parental prevention behaviours (OR 9.1, 95% PL 3.2, 31) and physician recommendation (OR 8.2, 95% PL 2.7, 30) had the highest magnitudes of association with influenza vaccination of healthy children in daycare. Our results provide evidence about critical determinants of influenza vaccination of healthy children in daycare, which could help inform public health interventions aimed at increasing influenza vaccination coverage in this population.

Patients with impaired kidney function are at increased risk of ventricular arrhythmia and sudden death. The association between chronic kidney disease and frontal T wave axis deviation, a cardiovascular risk factor, in individuals without heart disease is unexplored and unknown. To test the hypothesis that chronic kidney disease predicts frontal T-wave axis deviation, American participants 40 years of age or older from NHANES III, were categorized as having and not having chronic kidney disease based on glomerular filtration rates estimated by both serum cystatin C and serum creatinine and serum creatinine alone. Frontal T-wave axis deviation was measured from the standard 12-lead electrocardiogram. Multivariable adjustments for age, ace, smoking, metabolic syndrome, albuminuria, left ventricular mass, QRS duration and heart rate were performed. In multivariable weighted regression analysis, the odds ratio for abnormal frontal T wave axis deviations and their corresponding 95% CIs in patients with decreased glomerular filtration rate determined by an equation included cystatin and creatinine was 1.90 (1.20-3.32). The odds ratio of frontal T wave axis deviation due to decreased kidney function, determined using an equation included serum creatinine alone, was 1.65 (1.10-2.90). This study suggests that abnormal frontal T wave axis deviation abnormalities occur in subjects with chronic kidney disease. Those with decline in renal function should be considered at risk for potentially serious T-wave associated arrhythmias and thus carefully monitored.

IntroductionDespite continuing efforts to reduce tobacco use in the USA, decline in smoking rates have stalled and smoking remains a major contributor to preventable death. Implementation science could potentially improve uptake and impact of evidence-based tobacco control interventions; however, no previous studies have systematically examined how implementation science has been used in this field. Our scoping review will describe the use of implementation science in tobacco control in the USA, identify relevant gaps in research and suggest future directions for implementation science application to tobacco control.Methods and analysisOur team, including a medical research librarian, will conduct a scoping review guided primarily by Arksey and O’Malley’s methodology. We will search English language peer-reviewed literature published from 2000 to 31 December 2020 for terms synonymous with ‘tobacco use’, ‘prevention’, ‘cessation’ and ‘implementation science’. The databases included in this search are MEDLINE (PubMed), Embase (Ovid), CINAHL (EBSCOhost), PsycINFO (ProQuest), ERIC (ProQuest) and the Cochrane Library (Wiley). We will include cohort and quasi-experimental studies, single-group experiments and randomised trials that report qualitative and/or quantitative data related to applying implementation science to the planning and/or delivery of interventions to prevent or decrease the use of tobacco products. Studies must target potential or active tobacco users, intervention providers such as educators or healthcare professionals, or US policy-makers. A minimum of two reviewers will independently examine each title and abstract for relevance, and each eligible full text for inclusion and analysis. Use of implementation science, demonstrated by explicit reference to implementation frameworks, strategies or outcomes, will be extracted from included studies and summarised.Ethics and disseminationThis study is exempt from ethics board approval. We will document the equity-orientation of included studies with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Equity Extension checklist. Results will be submitted for conferences and peer-reviewed journals.Trial registration numberOpen Science Framework Registry (6YRK8).

Substance abuse treatment undergoes various changes in the event of a natural disaster. These changes may increase challenges for successful treatment completion for vulnerable populations such as those with a COD. Results of this study demonstrate that discharges with a COD are less likely to complete treatment as compared to those with no COD disorder. Unmet treatment needs may also increase odds of criminalization and homelessness.
