Background: Despite rising breast cancer incidence and mortality rates, breast cancer screening (BCS) rates among women in Qatar remain low. Previous studies indicate the need to better understand the many complex beliefs, values, and attitudes that influence Arab women's health seeking behavior for the development of culturally appropriate and effective intervention strategies to address breast cancer in the Middle East. This study investigates beliefs, attitudes, and BCS practices of Arabic-speaking women in Qatar. Methods: A multicenter, cross-sectional quantitative survey of 1,063 (87.5% response rate) Arabic-speaking female Qatari citizens and non-Qatari residents, 35 years of age or older, was conducted in Qatar from March 2011 to July 2011. Associations between beliefs and BCS practice were estimated using chi-square tests and multivariate logistic regression analyses. Participants who adhered to BCS guidelines (BCS practice = Yes) were compared to those who did not (BCS practice = No). Results: In addition to low levels of awareness and low participation rates in BCS, one quarter of the participants stated their doctors talked to them about breast cancer, and less than half of the women interviewed believed breast cancer can be prevented. Women who engaged in BCS practice were more likely to have a doctor who talked to them about breast cancer, to believe they were in good-excellent health, that cancer can be prevented, or that cancer might be hereditary. The majority wanted to know if they had cancer and felt their health care needs were being met. The main reasons given for not planning BCS were lack of a doctor's recommendation, fear, and embarrassment. Conclusions: These findings indicate that a variety of channels (health care providers, media, breast cancer survivors, community leaders) should be utilized to create culturally appropriate breast cancer intervention programs and increased awareness of breast cancer, BCS, and the benefits of early detection of breast cancer. Employment of these measures will reduce breast cancer mortality rates among Arabic-speaking women living in the State of Qatar. © 2013 Donnelly et al.; licensee BioMed Central Ltd.

The effects of a 5-month intervention of football instruction and practice on the perceived psychological status and body composition of overweight boys were examined. Twelve boys (8-12 years; body mass index≥85th percentile) participated in a structured 5-month football program, consisting of four weekly 60-90min sessions with mean heart rate>80%HRmax [football group (FG)]. A control group (CG) included eight boys of equivalent age from an obesity clinic located in the same area as the school. Both groups participated in two sessions of 45-90-min physical education per week at school. Indicators of perceived psychological status included body image, self-esteem, attraction to participation in physical activity, and perceived physical competence measured with standardized questionnaires. Body composition was evaluated using dual-energy X-ray absorptiometry. From baseline through 5 months, FG improved (P<0.05) in all indicators of psychological status (%Δ=+11.7 to +29.2%) compared with CG (%Δ=-32.1 to +0.5%). Changes in percentage body fat and lean body mass, however, did not differ between FG and CG. The findings suggest that a 5-month football intervention program was effective in improving the psychological status of overweight boys but did not significantly alter body composition. © 2014 John Wiley & Sons A/S.

This study set out to identify factors critical for the usability of electronic data collection in association with championships in individual sports. A qualitative analysis of electronic data collection system usability for collection of data on pre-participation health from athletes and in-competition injury and illness from team physicians was performed during the 2013 European Athletics Indoor Championships. A total of 15 athletes and team physicians participated. Athletes were found to experience few problems interacting with the electronic data collection system, but reported concerns about having to reflect on injury and illness before competitions and the medical terminology used. Team physicians encountered problems when first navigating through the module for clinical reporting, but they were not subjected to motivational problems. We conclude that athletes motivation to self-report health data and the design of the human-computer interface for team physicians are key issues for the usability of electronic data collection systems in association with championships in individual sports.

Muscle injuries are among the most common injuries in sport and continue to be a major concern because of training and competition time loss, challenging decision making regarding treatment and return to sport, and a relatively high recurrence rate. An adequate classification of muscle injury is essential for a full understanding of the injury and to optimize its management and return-to-play process. The ongoing failure to establish a classification system with broad acceptance has resulted from factors such as limited clinical applicability, and the inclusion of subjective findings and ambiguous terminology. The purpose of this article was to describe a classification system for muscle injuries with easy clinical application, adequate grouping of injuries with similar functional impairment, and potential prognostic value. This evidence-informed and expert consensus-based classification system for muscle injuries is based on a four-letter initialism system: MLG-R, respectively referring to the mechanism of injury (M), location of injury (L), grading of severity (G), and number of muscle re-injuries (R). The goal of the classification is to enhance communication between healthcare and sports-related professionals and facilitate rehabilitation and return-to-play decision making.

PURPOSE: A dysfunction of the quadriceps muscle group has often been suggested to play an important role in the pathophysiology of patellofemoral pain (PFP). However, consensus is lacking regarding the quadriceps recruitment pattern of patients with PFP. The aim of this study was to examine by muscle functional magnetic resonance imaging if patients with PFP actually exhibit an altered activation of the muscles that play a significant role in the dynamic balance of the patella. METHODS: Forty-six patients with PFP (25 female and 21 male, mean ± SD age = 25.0 ± 7.4 yr) and 30 healthy control subjects (17 female and 13 male, mean ± SD age = 21.6 ± 4.5 yr) underwent MRI of the quadriceps before and immediately after a squat exercise. The transverse relaxation time (T2) and the T2 shift were calculated for the vasti muscles. RESULTS: There were no significant differences in the T2 values at rest and the T2 shift values between the patient and the control groups, except for the T2 rest value of the VMVI of females (P = 0.007). The T2 shift of the VL was significantly smaller than the T2 shift of the VMVI in both study groups (male P < 0.001 and female P = 0.044), while in females, the T2 shift of the VMO was also significantly smaller than the T2 shift of the VMVI (P = 0.027). CONCLUSIONS: The activation pattern of the quadriceps is not altered in patients with PFP for both males and females. Because the relative contribution of the quadriceps muscles to a functional activity has not been modified, there is no evidence for quadriceps dysfunction.

Background: Enhancing the accuracy of a risk factor screening test is an important element of sports injury prevention. Purpose: To determine the effect of muscle fatigue on a screening tool for those at risk of exertional medial tibial pain (EMTP). Study Design: Cohort study (prognosis); Level of evidence, 2. Methods: Sixty-nine female students in a physical education program with a mean age of 1924 ± 0,86 years were tested at the beginning of their first academic year and followed for 1 to 2 years. Participants completed an online questionnaire every week and a retrospective control questionnaire every 3 months, which were used to assess injury follow-up. A diagnosis of EMTP was made by an experienced medical doctor. A Cox regression analysis was used to identify the potential risk factors by comparing prefatigue and postfatigue data between uninjured participants and those with EMTP. Both the leg that developed EMTP and the contralateral leg were compared with legs of a matched control group. Results: During injury follow-up, 21 female participants were diagnosed with EMTP. Results of the comparison between uninjured versus EMTP participants, respectively, are as follows: For the leg at risk in the nonfatigued state, only increased range of motion in the transverse plane (ROMT) of the hip during landing could be identified as a risk factor (8.44° ± 2.94° vs 11.69° ± 3.41 °; P = .002). In the fatigued state, increased ROMT of the hip and pelvis during landing (hip: 8.04° ± 2.34° vs 9.36° ± 3.22°; P = .038; pelvis: 6.99° ± 2.20" vs 8.58° ± 3.13°; P = .040) and increased ROMT of the thorax during pushoff (8.83° ± 2.74° vs 10.69° ± 3.20°; P = .036) could be identified. For the leg not at risk for EMTP, increased ROMT of the knee during landing (10.96° ± 3.12° vs 14.07" ± 4.88°; P = .023) and decreased ROMT of the pelvis during pushoff (8.16° ± 3.48° vs 6.47° ± 2.47°; P = .034) were identified in the nonfatigued state but were not significant in the fatigued state. Conclusion: Adding a muscle fatigue protocol to the single-legged drop jump as a screening test for EMTP risk factors may enhance the possibility of identifying the leg at risk in a predisposed athlete and might determine the proximal risk factors for that leg at risk more thoroughly. © 2014 The Author(s).

Objective To prospectively determine risk factors contributing to the development of exertional medial tibial pain (EMTP). Methods Data were prospectively collected on healthy female students in physical education, who were freshmen in 2010-2011 and 2011-2012. Eighty-six female students aged 19.38±0.85 years, were tested at the beginning of their first academic year. Kinematic parameters in the frontal and transverse plane were measured during a single-leg drop jump (SLDJ). For further analysis, the SLDJ task was divided in two phases: touchdown until maximal knee flexion (MKF) and then MKF until take-off, representing landing and push-off phase, respectively. The injury follow-up of the students was assessed using a weekly online questionnaire and a 3-monthly retrospective control questionnaire. EMTP was diagnosed by an experienced medical doctor. Cox regression analysis was used to identify the potential risk factors for the development of EMTP. Results During injury follow-up (1-2 years), 22 participants were diagnosed with EMTP. The results of this study identified that increased range of motion (ROM) in the transverse plane of hip and thorax during landing (p=0.010 and 0.026, respectively) and during push off (p=0.019 and 0.045, respectively) are predictive parameters for the development of EMTP in women. Conclusions Increased ROM values of hip and thorax in the transverse plane, which can be interpreted as impaired ability to maintain dynamic joint stability resulting in increased accessory movements, are significant contributors to the development of EMTP in women.

Hamstring acute muscle injuries are prevalent in several sports including AFL football (Australian Football League), sprinting and soccer, and are often associated with prolonged time away from sport.In response to this, research into prevention and management of hamstring injury has increased, but epidemiological data shows no decline in injury and re-injury rates, suggesting that rehabilitation programs and return to play (RTP) criteria have to be improved. There continues to be a lack of consensus regarding how to assess performance, recovery and readiness to RTP, following hamstring strain injury.The aim of this paper was to propose rehabilitation protocol for hamstring muscle injuries based on current basic science and research knowledge regarding injury demographics and management options.Criteria-based (subjective and objective) progression through the rehabilitation program will be outlined along with exercises for each phase, from initial injury to RTP.

Background: To evaluate the efficacy of a single platelet-rich plasma (PRP) injection in reducing the return to sport duration in male athletes, following an acute hamstring injury. Methods: A randomised, three-arm (double-blind for the injection arms), parallel-group trial, in which 90 professional athletes with MRI positive hamstring injuries were randomised to injection with PRP-intervention, platelet-poor plasma (PPP-control) or no injection. All received an intensive standardised rehabilitation programme. The primary outcome measure was time to return to play, with secondary measures including reinjury rate after 2 and 6 months. Results: The adjusted HR for the PRP group compared with the PPP group was 2.29 (95% CI 1.30 to 4.04) p=0.004; for the PRP group compared with the no injection group 1.48 (95% CI 0.869 to 2.520) p=0.15, and for the PPP group compared with the no injection group 1.57 (95% CI 0.88 to -2.80) p=0.13. The adjusted difference for time to return to sports between the PRP and PPP groups was -5.7 days (95% CI -10.1 to -1.4) p=0.01; between the PRP and no injection groups -2.9 days (95% CI -7.2 to 1.4) p=0.189 and between the PPP and no injection groups 2.8 days (95% CI -1.6 to 7.2) p=0.210. There was no significant difference for the secondary outcome measures. No adverse effects were reported. Conclusions: Our findings indicate that there is no benefit of a single PRP injection over intensive rehabilitation in athletes who have sustained acute, MRI positive hamstring injuries. Intensive physiotherapy led rehabilitation remains the primary means of ensuring an optimal return to sport following muscle injury. © 2015 Br J Sports Med.
