Intra-articular Hymovis injection for managing hip OA in active sportsmen. A 24-month observational retrospective clinical investigation

BACKGROUND

Hip Osteoarthitis (OA) risk is sport-specific and depends on frequency, intensity, and type of mechanic stress the hip is subjected to. This retrospective observational study aims to investigate the safety and performance of Hymovis (HYADD-4) injection, a hexadecyl (C-16) HA-derivative, when used to manage symptomatic hip OA in active middle-aged sportsmen over a 24-month observation period.

METHODS

The retrospective analysis included clinical records of active sportsmen, aged between 40 and 65 years, and suffering from symptomatic Kellgren-Lawrence grade II to III hip OA, treated with two (24 mg/3 ml) Hymovis injections, two weeks apart, every 3-4 months, for two years. When available, data on MRI examination were included in the analysis as well as Heidelberg Sports Activity Score (HAS) and Copenhagen Hip and Groin Outcome Score (HAGOS) questionnaires.

RESULTS

Thirty patients (56.4 ± 7.3 years) were included in the study, sixteen cyclists and 14 tennis players. For all patients, HAS and most HAGOS scores improved significantly (p < 0.05) at the first control visit (4 months) and further improved over time. For all other scores an important clinical benefit was experienced by more than 50% of participants. No adverse events were recorded.

CONCLUSION

Treatment of hip OA in active sportsmen with Hymovis seems a safe and effective approach for the management of OA symptoms, by potentially protecting cartilage and subchondral bone from further damage.

A Khorasan wheat-based diet improves systemic inflammatory profile in semi-professional basketball players: a randomized crossover pilot study

BACKGROUND/OBJECTIVES

Khorasan wheat is an ancient grain with widely acclaimed beneficial effects on human health. The objective of the study was to examine the effect of a Khorasan-based diet on the wellbeing and inflammatory profile of young athletes.

RESULTS

We conducted a randomized, single-blinded crossover trial involving 20 male young athletes. The participants were randomly assigned to consume products (pasta, bread, biscuits and crackers) made either with Khorasan (KAMUT® brand) or modern semi-whole-grain wheat for 4-weeks with a 4-week washout period before the crossover. Laboratory analyses and fitness tests were performed both at the beginning and end of each diet period. The consumption of Khorasan products was associated with a significant reduction of monocyte chemoattractant protein-1 (MCP-1; mean reduction: -36.15 pg/mL; -25.67%) while the consumption of modern wheat was not associated with significant differences in Interleukin-8 (IL-8) or Interleukin-1 receptor antagonist (IL-1ra). The consumption of the Khorasan-based diet also resulted in a significant improvement in self-rated health status. No statistically significant differences in any athletic performance parameter were observed between the two diets.

CONCLUSION

The present results suggest that a Khorasan-based diet could be effective in reducing the inflammatory status in young athletes. © 2019 Society of Chemical Industry.

Perception of aging in the relation between sport activity and self-rated health in middle and older age - A longitudinal analysis

Background

This study aims to generate more comprehensive knowledge regarding underlying mechanisms of health production in middle and older age by focusing on perception of aging in the relation between sport activity and self-rated health. More differentiated information can be generated by using more age-specific data and applying advanced empirical methods.

Methods

Panel data from the German Ageing Survey (DEAS) (n = 1027) is used, whereby individuals are included, that participated at least in two waves. First, a blockwise fixed effects logistic regression model is carried out, which allows to investigate mediation as well as moderation effects and controls for time invariant unobserved heterogeneity. Additionally, two recursive bivariate probit models are conducted to identify further indirect pathways.

Findings

A mediating and moderating effect of perception of aging regarding self-rated health is found in the fixed effects model. Indirect pathways of perception of aging and retirement over sport activity (mediator) are confirmed in the recursive bivariate probit models.

Conclusion

The results highlight the complexity of the underlying mechanisms as well as the importance of individual and needs-based designed health promotion. Here, public health policy should not solely focus on sport activity, rather it should include target group specific strategies to shape individual perceptions of aging towards a more positive view on aging, while considering the heterogeneity of middle and older age groups.

•

Sport activity and health-specific perception of aging are positively associated with self-rated health.

•

A mediating and moderating effect of perception of aging on sport activity regarding self-rated health is found.

•

Indirect pathways of perception of aging and retirement over sport activity are confirmed.

A group- and smartphone-based psychological intervention to increase and maintain physical activity in patients with musculoskeletal conditions: study protocol for a randomized controlled trial ("MoVo-App")

Abstract

Background

Interventions designed to increase the level of physical activity are crucial in the treatment of patients with musculoskeletal conditions. The psychological group-based intervention MoVo-LISA based on the Motivation-Volition (MoVo) Process Model has been shown to effectively promote physical activity. The aim of this study is to evaluate whether a MoVo-based app (MoVo-App) subsequent to MoVo-LISA during orthopedic inpatient care can support people to increase and maintain their amount of physical activity.

Methods/design

In this parallel-group randomized controlled trial, patients with musculoskeletal disorders will be randomized to either (a) a combination of the group-based intervention program MoVo-LISA to promote physical activity plus the MoVo-App or (b) the group-based intervention program alone without the app. The intervention group will receive the MoVo-App after discharge from inpatient rehabilitation. They receive help to increase and maintain their level of physical activity (initiated by the group program) by tracking their health goals, activity plans, major barriers, and barrier management that were developed during the group-based program. We will recruit 224 initially minimally active participants during orthopedic rehabilitation care. Outcomes are assessed at clinic admission; discharge; 6 weeks; and 3 (post-treatment), 6, and 12 months after discharge (follow-up). The primary outcome is sport activity (active/inactive and minutes of activity) at 6-month follow-up. Secondary outcomes are movement activity, cognitive mediators of behavioral change (e.g., self-efficacy, action planning), and health-related variables (e.g., pain intensity, depression). To evaluate intervention effects, linear mixed effects models (both on intention-to-treat basis with an additional per-protocol analysis) will be conducted with each outcome variable and with time as the within-subjects factor and group as the between-subjects factor, along with all two-way interactions and accounting for covariates as fixed effects.

Discussion

This is the first evaluation of the effectiveness of an app in combination with a face-to-face group intervention to promote physical activity. The approach of using an app in addition to an effective face-to-face intervention program, both based on the MoVo model, might sustain positive intervention effects introduced in routine health care.

Return to sport activity after anterior cruciate ligament reconstruction: A 6-10 years follow-up

BACKGROUND

Nowadays, patients widely accept anterior cruciate ligament (ACL) reconstructive surgery. However, its long-term complications are still under investigation in athletes. Therefore, the aim of this study was to evaluate long-term ACL reconstruction especially in athletes.

METHODS

A total of 426 patients with ACL injury were studied during 2008-2012. Demographic characteristics (gender, age, BMI), graft type, chondral lesion, osteoarthritis, meniscus tear, exercise activity, and pain intensity were noted. The effects of these factors on the return to sport activity after ACL reconstruction were also investigated. Lachman test, KT-1000, ACL quality of life (ACL-QOL), KOOS score, IKDC, and LKS were assessed at 2 years post-operation and at final follow-up. Repeated ACL rupture on the same and contralateral sides were also evaluated.Results: knee stability (based on Lachman and KT-1000), knee function (according to KOOS, LKS, and IKDC scores) and ACL-QOL were improved during the 2 years follow-up. The rate of return to sport activity similar to preinjury in patients was 64.08% in final follow-up. Chondral lesion was a limiting factor among the variables that affected the return to sport activity. It caused a return to sport activity similar to pre injury just in 21.24% of the patients. However, meniscus rupture did not affect return to sport activity similar to pre injury. Also, the rate of return to sport activity similar to pre injury was higher in men, patients under 30 years and those who had BMI of 20-25 kg/m². In final follow-up, risk of ACL rupture in the injured knee and contralateral knee was 4.22% and 10.57%, respectively.

CONCLUSION

Despite the recovery of patients after ACL reconstruction during long-term follow-up in athletes, return to sport activity similar to pre-injury in female, older peoples, overweight patients and athletes with chondral lesion were lower. However, these conditions do not apply to the meniscus rupture.

[Health of the unemployed and its effects on labour market integration : Results of the Labour Market and Social Security (PASS) panel study, waves 3 to 7 (2008/09-2013)]

BACKGROUND

According to existing research, unemployment is related to health problems. The causal relationship is not yet fully understood. This secondary data analysis aims to study the interdependencies between unemployment and health.

METHODS

This study is based on data from the German Labour Market and Social Security (PASS) panel study comprising a sample of beneficiaries of the Federal Employment Agency and their household members as well as a representative household sample. A total of 12,570 persons (aged 15 to 64 years) from 8,392 households were interviewed in wave 7 (2013) of PASS.

RESULTS

The employed and unemployed differ substantially in terms of socio-demographic and health-related characteristics. Unemployed persons more often report worse or bad self-rated health (unemployed men: 31.0 % vs. employed men: 14.0 %; unemployed women: 37.7 % vs. employed women: 21.7 %) and feel being rather or much impaired by mental problems (unemployed men: 21.9 % vs. employed men: 7.2 %; unemployed women: 20.4 % vs. employed women: 15.8 %). For the unemployed, the proportion with an officially certified severe disability as well as another severe health impairment is much higher. They also more often report at least one hospital stay in the previous 12 months (unemployed men: 16.3 % vs. employed men: 9.9 %; unemployed women: 19.6 % vs. employed women: 12.2 %) and more contacts with physicians. In spite of that, unemployed persons do less exercise. Multivariate, longitudinal, logistic regression models demonstrate strong health-related selection effects on labour market transitions. Lower self-rated health is associated with a higher unemployment risk for employed persons as well as a lower probability of reintegration for unemployed persons. The most influential determinants of bad self-rated health are self-rated health status in the year before, while job loss and re-employment tend to influence the occurrence of bad self-rated health.

DISCUSSION

The analyses show substantial health disparities to the detriment of the unemployed. They also refer to a need for prevention regarding healthcare and employment.

Ventricular arrhythmias in competitive athletes: risk stratification with T-wave alternans

Introduction:

Aim of our study is to evaluate the role of TWA to stratify the risk of sudden cardiac death in athletes (Ath) with complex ventricular arrhythmias (VA), and to document a possible correlation between TWA and electrophysiological testing (EES) results.

Methods:

We studied 43 Ath with VA (31 M, mean age 34 ± 12 years). In all cases a cardiological evaluation was performed, including TWA and EES. The patients were evaluated during a follow-up of 25 ± 22 months. The end-point was the occurrence of sudden death or malignant ventricular tachyarrhythmias (VT).

Results:

TWA was negative in 28 Ath (65%), positive in 8 (19%) and indeterminate in 7 (16%). All subjects with negative TWA did not show induction of VT at EES, with significant correlation between negative TWA and negative EES (p<0.001). All Ath with positive TWA also had VT induced by a EES, but without significant correlation between positive TWA and positive EES. In 2 Ath with undetermined TWA (29%) VT were induced at EES. Our data did not show significant correlation between indeterminate TWA and positive or negative EES. However, logistic regression analysis showed significant correlation between abnormal TWA test (positive or indeterminate) and inducibility of VT at EES (p<0.001). During follow-up we observed a significant difference in end-point occurrence between Ath with negative or positive TWA and between Ath with negative or positive EES.

Conclusion:

TWA confirm its role as a simple and non-invasive test, and it seems useful for prognostic stratification of Ath with VA.
