Sudden cardiac arrest in athletes and strategies to optimize preparedness

Sudden cardiac arrest (SCA) is the leading cause of death in young athletes. Despite efforts to improve preparedness for cardiac emergencies, the incidence of out-of-hospital cardiac arrests in athletes remains high, and bystander awareness and readiness for SCA support are inadequate. Initiatives such as designing an emergency action plan (EAP) and mandating training in cardiopulmonary resuscitation (CPR) and automated external defibrillator use (AED) for team members and personnel can contribute to improved survival rates in SCA cases. This review provides an overview of SCA in athletes, focusing on identifying populations at the highest risk and evaluating the effectiveness of different screening practices in detecting conditions that may lead to SCA. We summarize current practices and recommendations for improving the response to SCA events, and we highlight the need for ongoing efforts to optimize preparedness through the implementation of EAPs and the training of individuals in CPR and AED use. Additionally, we propose a call to action to increase awareness and training in EAP development, CPR, and AED use for team members and personnel. To improve outcomes of SCA cases in athletes, it is crucial to enhance bystander awareness and preparedness for cardiac emergencies. Implementing EAPs and providing training in CPR and AED use for team members and personnel are essential steps toward improving survival rates in SCA cases.

Craving among individuals with stimulant use disorder in residential social model-based treatment - Can exercise help?

BACKGROUND

In a randomized controlled 8-week trial, we examined the efficacy of aerobic and resistance exercise in reducing craving for methamphetamine (MA) among individuals with MA-use disorder during residential treatment.

METHODS

Individuals with MA use disorder (138) who were newly enrolled in residential treatment volunteered for random assignment to either an 8-week exercise intervention (EX) or health education control (HE), with both conditions meeting 3 times weekly; 3 dropped out of the trial, bringing the analysis sample to 135. The majority of participants were male (80%), and 48% were Latino/Hispanic. The mean age of the sample was 31.7 (SD = 6.9) years. Using multivariate mixed models, differences between conditions were examined in: (1) craving for MA, measured by self-reported ratings on a Visual Analog Scale over the 8-week trial and, (2) MA use, measured by self-report and urine drug screens at baseline and 30 and 60 days after discharge from the 8-week study.

RESULTS

Results revealed significantly lower craving scores among the participants in the EX group than those in the HE group over the 8-week trial (median daily craving score for EX = 13.5, for HE = 21.8; p = .009). In addition, participants with less craving during treatment had significantly lower rates of MA use after discharge than participants with high craving measured at 30-days (p = .004) and 60-days post-discharge (p < .001).

CONCLUSIONS

Results support the utility of incorporating a structured exercise program for individuals with MA-use disorder to reduce craving and improve MA-use outcomes.

Ratio of FEV1/Slow Vital Capacity of < 0.7 Is Associated With Clinical, Functional, and Radiologic Features of Obstructive Lung Disease in Smokers With Preserved Lung Function

BACKGROUND

Mild expiratory flow limitation may not be recognized using traditional spirometric criteria based on the ratio of FEV₁/FVC.

RESEARCH QUESTION

Does slow vital capacity (SVC) instead of FVC increase the sensitivity of spirometry to identify patients with early or mild obstructive lung disease?

STUDY DESIGN AND METHODS

We included 854 current and former smokers from the Subpopulations and Intermediate Outcome Measures in COPD Study cohort with a postbronchodilator FEV₁/FVC ≥ 0.7 and FEV₁ % predicted of ≥ 80% at enrollment. We compared baseline characteristics, chest CT scan features, exacerbations, and progression to COPD (postbronchodilator FEV₁/FVC, < 0.7) during the follow-up period between 734 participants with postbronchodilator FEV₁/SVC of ≥ 0.7 and 120 with postbronchodilator FEV₁/SVC < 0.7 at the enrollment. We performed multivariate linear and logistic regression models and negative binomial and interval-censored proportion hazards regression models adjusted for demographics and smoking exposure to examine the association of FEV₁/SVC < 0.7 with those characteristics and outcomes.

RESULTS

Participants with FEV₁/SVC < 0.7 were older and had lower FEV₁ and more emphysema than those with FEV₁/SVC ≥ 0.7. In adjusted analysis, individuals with postbronchodilator FEV₁/SVC < 0.7 showed a greater percentage of emphysema by 0.45% (95% CI, 0.09%-0.82%), percentage of gas trapping by 2.52% (95% CI, 0.59%-4.44%), and percentage of functional small airways disease based on parametric response mapping by 2.78% (95% CI, 0.72%-4.83%) at baseline than those with FEV₁/SVC ≥ 0.7. During a median follow-up time of 1,500 days, an FEV₁/SVC < 0.7 was not associated with total exacerbations (incident rate ratio [IRR], 1.61; 95% CI, 0.97-2.64), but was associated with severe exacerbations (IRR, 2.60; 95% CI, 1.04-4.89). An FEV₁/SVC < 0.7 was associated with progression to COPD during a 3-year follow-up even after adjustment for demographics and smoking exposure (hazard ratio, 3.93; 95% CI, 2.71-5.72). We found similar results when we examined the association of prebronchodilator FEV₁/SVC < 0.7 or FEV₁/SVC less than the lower limit of normal with chest CT scan features and progression to COPD.

INTERPRETATION

Low FEV₁ to SVC in current and former smokers with normal spirometry results can identify individuals with CT scan features of COPD who are at risk for severe exacerbations and is associated with progression to COPD in the future.

Impact of an exercise intervention on methamphetamine use outcomes post-residential treatment care

BACKGROUND

We examined the efficacy of an 8-week exercise intervention on posttreatment methamphetamine (MA) use among MA-dependent individuals following residential treatment.

METHODS

135 individuals newly enrolled in treatment were randomly assigned to a structured 8-week exercise intervention or health education control group. Approximately 1 week after completion of the intervention, participants were discharged to the community. Interview data and urine samples were collected at 1-, 3-, and 6-months post-residential care. Of the sample, 54.8% were classified as higher severity users (using MA more than 18 days in the month before admission) and 45.2% as lower severity users (using MA for up to 18 days in the month before admission). Group differences in MA use outcomes were examined over the 3 timepoints using mixed-multivariate modeling.

RESULTS

While fewer exercise participants returned to MA use compared to education participants at 1-, 3- and 6-months post-discharge, differences were not statistically significant. A significant interaction for self-reported MA use and MA urine drug test results by condition and MA severity was found: lower severity users in the exercise group reported using MA significantly fewer days at the three post-discharge timepoints than lower severity users in the education group. Lower severity users in the exercise group also had a lower percentage of positive urine results at the three timepoints than lower severity users in the education group. These relationships were not present in the comparison of the higher severity conditions.

CONCLUSION

Results support the value of exercise as a treatment component for individuals using MA 18 or fewer days/month.

The Impact of Exercise On Depression and Anxiety Symptoms Among Abstinent Methamphetamine-Dependent Individuals in A Residential Treatment Setting

BACKGROUND

This paper reports data from a study designed to determine the impact of an 8-week exercise program on depression and anxiety symptoms among newly abstinent methamphetamine (MA)-dependent individuals in residential treatment.

METHODS

One hundred thirty-five MA-dependent individuals, newly enrolled in residential treatment, were randomly assigned to receive either a 3-times-per-week, 60-minute structured exercise program for 8 weeks (24 sessions) or an equivalent number of health education sessions. Using mixed-modeling repeated-measures regression, we examined changes in weekly total depression and anxiety scores as measured by the Beck Depression Inventory and Beck Anxiety Inventory over the 8-week study period.

RESULTS

Mean age of participants was 31.7 (SD = 6.9); 70.4% were male and 48% Latino. Analyses indicate a significant effect of exercise on reducing depression (β = -0.63, P = 0.001) and anxiety (β = -0.95, P=0.001) symptoms (total scores) over the 8-week period compared to a health education control group. A significant dose interaction effect between session attendance and exercise was found as well on reducing depression (β = -0.61, P < 0.001) and anxiety symptoms (β = -0.22, P=0.009) over time compared to the control group.

CONCLUSIONS

Results support the role of a structured exercise program as an effective intervention for improving symptoms of depression and anxiety associated with MA abstinence.

Exercise for methamphetamine dependence: rationale, design, and methodology

BACKGROUND

Effective pharmacotherapies to treat methamphetamine (MA) dependence have not been identified, and behavioral therapies are marginally effective. Based on behavioral studies demonstrating the potential efficacy of aerobic exercise for improving depressive symptoms, anxiety, cognitive deficits, and substance use outcomes, the study described here is examining exercise as a potential treatment for MA-dependent individuals.

METHODS

This study is randomizing 150 participants with MA dependence at a residential treatment facility for addictive disorders to receive either a thrice-weekly structured aerobic and resistance exercise intervention or a health education condition. Recruitment commenced in March, 2010. Enrollment and follow-up phases are ongoing, and recruitment is exceeding targeted enrollment rates.

CONCLUSIONS

Seeking evidence for a possibly effective adjunct to traditional behavioral approaches for treatment of MA dependence, this study is assessing the ability of an 8-week aerobic and resistance exercise protocol to reduce relapse to MA use during a 12-week follow-up period after discharge from residential-based treatment. The study also is evaluating improvements in health and functional outcomes during and after the protocol. This paper describes the design and methods of the study.

[Insufficient anastomoses in sigmoideal and rectal resections. A retrospective study conducted in a surgical clinic in Hradec Králové]

INTRODUCTION

Anastomotic insufficiency is the primary cause of postoperative morbidity and mortality following resection procedures of the large intestine and rectum.

MATERIAL AND METHODOLOGY

In the retrostpective study, the authors analysed rates of rectal and sigmoideal anastomotic insufficiencies in patients operated for rectal and sigmoideal carcinomas in the Faculty Hospital Surgical Clinic in Hradec Králové from 2000 to 2004. At the same time, the authors analysed risk factors of the insufficiencies. The subject of protective derivation stomies is discussed.

RESULTS

In the group with primary colorectal anastomosis, the anastomotic insufficiency occured in 11% of the group subjects, in the group with primary sigmoideal anastomosis in 9.1% of the group subjects. Out of the total of 215 subjects, the anastomotic insufficiency occurred in 23 subjects (10.7 %), 6 cases were fatal and the overall postoperative mortality was 1.56 % . In the anastomotic insufficiency group, it reached 13.04 %. The difference between the studied groups is significant (p<0,001, OR = 10.5).

CONCLUSION

Postoperative mortality in sigmoideal and rectal resection procedures correlates with anastomotic insufficiency.

Cross-sectional study of nocturia in both sexes: analysis of a voluntary health screening project

OBJECTIVES

To assess the prevalence of nocturia and its impact on the quality of life in both sexes by analyzing almost 2500 individuals participating in a health survey.

METHODS

During a 12-month period, we included an incontinence questionnaire, which was largely based on the Bristol female lower urinary tract symptoms questionnaire, in the voluntary health examinations in the area of Vienna. In parallel, we recorded the medical history, concurrent medical therapy, physical examination findings, sociodemographic parameters, and blood laboratory study results.

RESULTS

The data of 1247 women (age 49.8 +/- 13.5 years) and 1221 men (age 48.5 +/- 11.9 years) were analyzed. The percentage of individuals with nocturia of two or more times increased constantly with age: less than 30 years, 3.1% of women and 3.4% of men; 30 to 59 years, 7.2% of women and 5. 7% of men; and 60 years old or older, 26.7% of women and 32.4% of men. Age-adjusted extrapolation to the general population (older than 20 years) currently living in Austria yielded that 10.8% of men and 11.8% of women have nocturia of two or more times. Overall, 66. 9% of women and 62.2% of men reported a negative impact of nocturia on their quality of life. The correlation was close between the degree of nocturia with the quality-of-life impairment in both sexes. Several voiding symptoms correlated significantly (P <0.001) with nocturia.

CONCLUSIONS

Nocturia is almost equally present in both sexes, and the incidence and severity increase constantly from early adolescence to senescence. Approximately 10% of the general population (older than 20 years) have nocturia of two or more times, which impairs the quality of life in two thirds.
