Supra-maximal speed interval training effect on a 40m standing start sprint and timed 3000m running performance in moderately trained female runners: Alterg anti-gravity treadmill running

The purpose of this study was to explore what the supra-maximal speed interval training effect was on a 40m standing start sprint and timed 3000m running performance was for two separate study groups when using either the AlterG® anti-gravity treadmill, or downhill running as a training intervention, for moderately trained female runners. The level of delayed onset of muscle soreness (DOMS) after each supra-maximal speed interval session was also captured. Data from 20 women was collected during initial pre-intervention testing; involving the 40m standing start sprint and 3000m timed trial run. During a four week training intervention the level of DOMS experienced by participants at increments of 24 hours, 48 hours and 72 hours, in each respective training group was recorded. Post-intervention testing was performed to once again measure the participants 40m standing start sprint and 3000m timed trial run values, results were analysed and compared to pre-intervention data

Personality Pathology Severity and Hazardous Cannabis Use: Does Instability in Daily Life Mediate This Association?

Comorbidities between personality pathology and cannabis use disorders among young adults are a growing public health concern. Young adulthood is the period in which personality pathology and associated dysfunction peak, and evidence suggests personality pathology contributes to substance abuse behaviors. However, the specific aspects of personality pathology that explain these associations remain unclear. Personality disorders tend to share in common three domains of dysregulation that are marked by instability in self-esteem (identity), affect, and interpersonal experiences. This study investigated whether these common domains of personality dysfunction mediated associations between personality pathology severity and patterns of cannabis use. The current study used data from a community-based sample of 186 young adults (ages 18-30; mean age = 21.09 years [SD = 2.35], 60% female, 72% White; 74% college students) who reported using cannabis at least twice per month over the past six months. Momentary data on psychological states and cannabis use were collected via 8 daily surveys over 21 days. Mediation analyses showed indirect effects of personality pathology severity on hazardous cannabis use through within-day instability in self-esteem and in interpersonal experiences, but not through instability in affect. Further, participants with greater personality pathology demonstrated greater instability, but instability was associated with less hazardous cannabis use. These unexpected results emphasize the need to consider interpersonal and identity-related constructs in research examining contributors to comorbid cannabis and personality pathology. Instability in self-esteem and in interpersonal experiences should be explored further in future studies, as they may be targets for clinical intervention in young adults with personality pathology who hazardously use cannabis

Simultaneous evaluation of abstinence and relapse using a Markov chain model in smokers enrolled in a two-year randomized trial

Abstract Background GEE and mixed models are powerful tools to compare treatment effects in longitudinal smoking cessation trials. However, they are not capable of assessing the relapse (from abstinent back to smoking) simultaneously with cessation, which can be studied by transition models. Methods We apply a first-order Markov chain model to analyze the transition of smoking status measured every 6 months in a 2-year randomized smoking cessation trial, and to identify what factors are associated with the transition from smoking to abstinent and from abstinent to smoking. Missing values due to non-response are assumed non-ignorable and handled by the selection modeling approach. Results Smokers receiving high-intensity disease management (HDM), of male gender, lower daily cigarette consumption, higher motivation and confidence to quit, and having serious attempts to quit were more likely to become abstinent (OR = 1.48, 1.66, 1.03, 1.15, 1.09 and 1.34, respectively) in the next 6 months. Among those who were abstinent, lower income and stronger nicotine dependence (OR = 1.72 for ≤ vs. > 40 K and OR = 1.75 for first cigarette ≤ vs. > 5 min) were more likely to have relapse in the next 6 months. Conclusions Markov chain models allow investigation of dynamic smoking-abstinence behavior and suggest that relapse is influenced by different factors than cessation. The knowledge of treatments and covariates in transitions in both directions may provide guidance for designing more effective interventions on smoking cessation and relapse prevention.

Acceptability and Feasibility of Web-based Diabetes Instruction for Latinos with Limited Education and Computer Experience

Introduction: The internet offers an important avenue for developing diabetes self-management skills, but many Latinos have limited experience with computer-based instruction. Objective: To evaluate the feasibility and acceptability of delivering a web-based diabetes education program in a computer classroom for Spanish-speaking Latinos. Methods: Spanish-speaking Latinos (n=26) attended two classroom sessions to learn computer skills while navigating a web-based diabetes education platform. Diabetes knowledge was assessed before and after the intervention; structured interviews were completed to assess program acceptability. Results: Half of participants (50%) had not previously used a computer. Post-intervention, diabetes knowledge improved significantly (p=.001). The majority of participants (86%) indicated a preference for web-based instruction as a stand-alone program or as an adjunct to traditional classroom training, particularly citing the advantage of being able to engage the material at their own pace. Conclusion: With limited support, Latinos with minimal computer experience can effectively engage in web-based diabetes education

An Evaluation of SmokeFree for Kansas Kids: An Intervention to Promote Tobacco Cessation in Pediatric Clinics

Introduction. Smokefree for Kansas Kids is a program designedto train pediatric clinic staff to assess for tobaccoexposure and provide brief smoking cessation interventionsto caregivers and patients. The purpose of this studywas to evaluate the impact of this program and improvefuture tobacco intervention efforts in pediatric clinics. Methods. Eighty-six pediatric physicians and staff attendedat least one of three training sessions. A randomsample of pediatric medical records was selected pre-intervention(n = 49) and post-intervention (n = 150). Electronicmedical records were reviewed to assess for documentationof tobacco use intervention implemented in the clinic. Results. Of the 199 pediatric clinic visits reviewed, 197 metthe study criteria. All but one visit documented an assessmentof tobacco exposure. Among children exposed to tobacco (n= 42), providers were more likely to discuss tobacco use withcaregivers post-intervention (35.7%) compared to pre-intervention(7.1%; p < 0.05). One in five caregivers in the postinterventiongroup were advised to quit (21.4%) compared tothe pre-intervention group (7.1%). In the post-interventiongroup, 14.3% were referred to the state quitline compared tono referrals in the pre-intervention group. The difference inrates for providing advice and referral between pre-interventionand post-intervention were not statistically significant. Conclusions. Implementation of the Smoke Free for Kansas Kidsintervention was associated with modest improvements in clinictobacco intervention efforts, but many patients still failed toreceive optimal assessments or interventions. Additional effortsmay be needed to enhance this program. KS J Med 2017;10(1):7-11
