The Back School programme when compared with the passive physical therapies (such as massage, ultrasound treatment, etc.) shows significant improvement in reduction in pain and greatly improves the posture of healthcare workers. The adoption of the Back School programme for the treatment of the healthcare workers with chronic low back problems should be a treatment of choice and standard that should be adopted when designing occupational healthcare policies and procedures.

Aim of the studyBystanders can play an important role in the event of sudden injury or illness. Our aim was to evaluate the effects of a 3-day first aid course for all primary school age groups (7–14 years old).Methods582 school children were involved in the study. Training consisted of three sessions with transfer of theoretical knowledge and practical skills about first aid. The following most urgent situations were addressed in our study: adult basic life support (BLS), using an automated external defibrillator (AED), handling an unconscious patient, managing bleeding and calling the ambulance. Data collection was made with a questionnaire developed for the study and observation. Students were tested before, immediately after and 4 months after training. Results were considered significant in case of p<0.05.ResultsPrior to training there was a low level of knowledge and skills on BLS, management of the unconscious patient, use of an AED and management of bleeding. Knowledge and skills improved significantly in all of these categories (p<0.01) and remained significantly higher than the pre-test level at 4 months after training (p<0.01). Younger children overall performed less well than older children, but significantly improved over the pre-test level both immediately and 4 months after training (p<0.01). Prior first aid training was associated with knowledge of the correct ambulance number (p=0.015) and management of bleeding (p=0.041). Prior to training, age was associated with pre-test knowledge and skills of all topics (p<0.01); after training, it was only associated with AED use (p<0.001). There was a significant correlation between the depth of chest compression and children’s age, weight, height and body mass index (p<0.001). Ventilation depended on the same factors (p<0.001).ConclusionChildren aged 7–14 years are able to perform basic life-saving skills. Knowledge retention after 4 months is good for skills, but thinking in algorithms is difficult for these children.

After months of restrictive containment efforts to fight the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) epidemic, European countries are planning to reopen. To support the process, we conducted a cross-sectional survey among the Hungarian population to estimate the prevalence of

BackgroundBoth gravitational loading and the forces generated by muscle contraction have direct effects on serum markers of bone metabolism. The object of this study was to examine the direct effects of a single session of resistance exercise or walking on biochemical markers of bone metabolism in participants with low bone mass.MethodsA total of 150 otherwise healthy female subjects (mean age = 59.1 ± 7.1 years) diagnosed with osteoporosis or osteopenia were randomly allocated to either a resistance exercise group (RG; n = 50), walking group (WG; n = 50), or control group (CG; n = 50). Changes in bone-specific alkaline phosphatase (BALP), carboxy-terminal cross-linked telopeptide of type I collagen (CTX), and serum sclerostin concentrations were measured before and immediately after a single exercise intervention.ResultsThere was no significant change in BALP values in any of the groups. Sclerostin levels increased in the RG and WG, and there was significant difference between the WG and CG after the exercise intervention (P < 0.01). In contrast, the changes in CTX concentrations from baseline were significant in the RG (P < 0.01) but not in the WG (P = 0.11), and there was a significant difference between resistance exercise and walking (P < 0.01).ConclusionsIn participants with low bone mass, resistance exercise influenced the serum concentrations of CTX, a marker of bone resorption, but walking did not.Trial registrationCurrent Controlled Trials ISRCTN16329455; retrospectively registered on 05/05/2016.
