Background and Aims Due to their small sample sizes, geographic specificity and limited examination of socio-demographic characteristics, recent studies of methamphetamine use among people using heroin in the United States are limited in their ability to identify national and regional trends and to characterize populations at risk for using heroin and methamphetamine. This study aimed to examine trends and correlates of methamphetamine use among heroin treatment admissions in the United States. Design Longitudinal analysis of data from the 2008 to 2017 Treatment Episode Data Set.Descriptive statistics, trend analyses and multivariable logistic regression were used to examine characteristics associated with methamphetamine use among heroin treatment admissions. Setting United States. Participants Treatment admissions of people aged ≥ 12 years whose primary substance of use is heroin. Measurements Primary measurement was heroin treatment admissions involving methamphetamine. Secondary measurements were demographics of sex, age, race/ethnicity, US census region, living arrangement and employment status. Findings The percentage of primary heroin treatment admissions reporting methamphetamine use increased each year from 2.1% in 2008 to 12.4% in 2017, a relative percentage increase of 490% and an annual percentage change (APC) of 23.4% (P < 0.001). During the study period, increases were seen among males and females and among all demographic and geographic groups examined. Among primary heroin treatment admissions reporting methamphetamine use in 2017, 47.1% reported injecting, 46.0% reported smoking, 5.1% reporting snorting and 1.8% reported oral/other as their usual route of methamphetamine use. Conclusions Methamphetamine use among heroin treatment admissions in the United States increased from one in 50 primary heroin treatment admissions in 2008 to one in 8 admissions in 2017.
In 2011-2012, only 34% of 13-17 years olds in the United States (US) received seasonal influenza vaccine. Little is known about the link between parents' sources of health information, their vaccine-related attitudes, and vaccination of their adolescent against influenza. This study seeks to determine the relationship between number of sources of information on influenza vaccine, parental attitudes toward influenza vaccine, and influenza vaccine uptake in adolescents. We conducted a telephone and web-based survey among US parents of students enrolled in 6 middle and 5 high schools in Georgia. Bivariate and multivariable analyses were conducted to examine associations between the number of information sources about influenza vaccine and vaccine receipt and whether parent vaccine-related attitudes act as a mediator. The most commonly reported sources of information were: a physician/medical professional (95.0%), a family member or friend (80.6%), and television (77.2%). Parents who had higher attitude scores toward influenza vaccine were 5 times as likely to report their adolescent had ever received influenza vaccine compared to parents who had lower attitude scores (adjusted odds ratio (aOR) 5.1; 95% confidence intervals (CI) 3.1-8.4; P < 0.01). Parent vaccine-related attitudes were a significant mediator of the relationship between sources of information and vaccine receipt. In light of the low response rate and participation in an adolescent vaccination intervention, findings may not be generalizable to other populations. This study shows the importance of multiple sources of information in influencing parental decision-making about influenza vaccine for adolescents. Harnessing the power of mass media and family members and friends as health advocates for influenza vaccination can potentially help increase vaccination coverage of adolescents.
Four vaccines are recommended by The Advisory Committee for Immunization Practices for adolescents: tetanus, diphtheria, acellular pertussis vaccine (Tdap), meningococcal conjugate vaccine (MCV4), human papillomavirus vaccine (HPV), and annual seasonal influenza vaccine. However, coverage among adolescents is suboptimal. School-located vaccination clinics (SLVCs) offer vaccines to students at school, increasing access. This study seeks to determine the relationship between attitudes of parents of middle- and high-school students and acceptance of SLVCs for all four adolescent recommended vaccines. We conducted a telephone and web-based survey among parents of students enrolled in six middle and five high schools in Georgia. Analyses were conducted to examine associations between parental attitudes and willingness to allow their child to be vaccinated at school. Tdap and influenza vaccine had the highest rates of parental SLVC acceptance while HPV vaccine had the lowest. Parents who accepted SLVCs had higher perceived severity of influenza, meningococcal, and HPV illnesses compared to parents who did not accept SLVC. Intention to vaccinate was associated with SLVC acceptance for Tdap [Adjusted OR (AOR) 7.38; 95% confidence interval (CI) 2.44-22.31], MCV4 (AOR 2.97; 95% CI 1.67-5.28), and HPV vaccines (AOR 7.61; 95% CI 3.43-16.89). Social norms were associated with acceptance of SLVCs for influenza vaccine (AOR 1.44; 95% CI 1.12-1.84). These findings suggest parents of adolescents are generally supportive of SLVCs for recommended adolescent vaccines. Perceived severity of illness and intention to get their adolescent vaccinated were the most consistent correlates of parental SLVC acceptance for all vaccines. Future SLVC planning should focus on perceptions of disease severity and benefits of vaccination.
Human papillomavirus (HPV) vaccination coverage for adolescent females and males remains low in the United States. We conducted a 3-arm randomized controlled trial (RCT) conducted in middle and high schools in eastern Georgia from 2011-2013 to determine the effect of 2 educational interventions used to increase adolescent vaccination coverage for the 4 recommended adolescent vaccines: Tdap, MCV4, HPV and influenza. As part of this RCT, this article focuses on: 1) describing initiation and completion of HPV vaccine series among a diverse population of male and female adolescents; 2) assessing parental attitudes toward HPV vaccine; and 3) examining correlates of HPV vaccine series initiation and completion. Parental attitude score was the strongest predictor of HPV vaccine initiation among adolescents (adjusted odds ratio (aOR): 2.08; 95% confidence interval (CI): 1.80, 2.39). Other correlates that significantly predicted HPV series initiation were gender, study year, and intervention arm. Parental attitudes remained a significant predictor of receipt of 3 doses of HPV vaccine along with gender, race, school type and insurance type. This study demonstrates that positive parental attitudes are important predictors of HPV vaccination and critical to increasing coverage rates. Our findings suggest that more research is needed to understand how parental attitudes are developed and evolve over time.
The prevalence of taste disorders in children was high and exceeded the level (4%) designated by the World Health Organisation as requiring immediate action by health authorities. As the cause of the disorders is unknown, there is a need for a wider investigation of the causes and the consequences.
BACKGROUND:In this study, we assessed impact of two educational interventions designed to increase coverage of three vaccines recommended during adolescence among Georgia middle and high school students (tetanus diphtheria pertussis [Tdap], meningococcal [MenACWY], and human papillomavirus [HPV] vaccines). METHODS:We randomized 11 middle and high schools in one school district into one of three arms: (1) control; (2) educational intervention for parents only (P only); and (3) multicomponent educational intervention for parents and adolescents (P + A), which consisted of educational brochures for parents about vaccines recommended during adolescence and a vaccine-focused curriculum delivered to adolescents by science teachers. We obtained vaccination coverage data during intervention years from the state immunization registry. RESULTS:Odds of receiving at least one vaccine during the study were higher among adolescents in P + A arm compared to control (Odds Ratio [OR]: 1.4; 95% Confidence Interval [CI]: 1.1-2.0). Adolescents in P + A arm had greater odds of receiving at least one vaccine compared with those in P only arm (OR: 1.4; 95% CI: 1.1-1.7). CONCLUSIONS:A multicomponent educational intervention for adolescents and parents increased adolescent vaccination uptake. Results suggest similar interventions can increase awareness and demand for vaccines among parents and adolescents.
Mild traumatic brain injury is a relatively common event in contact sports and there is increasing interest in the long-term neurocognitive effects. The diagnosis largely relies on symptom reporting and there is a need for objective tools to aid diagnosis and prognosis. There are recent reports that blood biomarkers could potentially help triage patients with suspected injury and normal CT findings. We have measured plasma concentrations of glial and neuronal proteins and explored their potential in the assessment of mild traumatic brain injury in contact sport. We recruited a prospective cohort of active male rugby players, who had pre-season baseline plasma sampling. From this prospective cohort, we recruited 25 players diagnosed with mild traumatic brain injury. We sampled post-match rugby players without head injuries as post-match controls. We measured plasma neurofilament light chain, tau and glial fibrillary acidic protein levels using ultrasensitive single molecule array technology. The data was analysed at the group and individual player level. Plasma glial fibrillary acidic protein concentration was significantly increased 1-hour post-injury in mild traumatic brain injury cases compared to the non-injured group (p = 0.017). Pairwise comparison also showed that glial fibrillary acidic protein levels were higher in players after a head injury in comparison to their pre-season levels at both 1-hour and 3 to 10-days post-injury time points (p = 0.039 and 0.040, respectively). There was also an increase in neurofilament light chain concentration in brain injury cases compared to the pre-season levels within the same individual at both time points (p = 0.023 and 0.002, respectively). Tau was elevated in both the non-injured control group and the 1-hour post-injury group compared to pre-season levels (p = 0.007 and 0.015, respectively). Furthermore, receiver operating characteristic analysis showed that glial fibrillary acidic protein and neurofilament light chain can separate head injury cases from control players. The highest diagnostic power was detected when biomarkers were combined in differentiating 1-hour post-match control players from 1-hour post head injury players (area under curve 0.90, 95% confidence interval 0.79-1.00, p < 0.0002). The brain astrocytic marker glial fibrillary acidic protein is elevated in blood 1 hour after mild traumatic brain injury and in combination with neurofilament light chain displayed the potential as a reliable biomarker for brain injury evaluation. Plasma total tau is elevated following competitive rugby with and without a head injury, perhaps related to peripheral nerve trauma, and therefore total tau does not appear to be suitable as a blood biomarker.
