Early Intervention, Regular Education, and Family: Reciprocal Influences on Communication and Language Disorders.

Families are the primary caregivers and the main source of support for their children. Family resilience involves coping and adapting to stressful situations. This study explored the impact of previous treatment experience on parental resilience, in families, as well as the relationship between family history of communication and language disorders and parental stress. These variables were assessed through the Resilience Scale and the Parental Stress Index in parents of 220 children aged 3 to 6 years attending mainstream schools and early intervention (EI) centers in Caceres (Spain). The results revealed significant differences in resilience between parents who had received previous treatments and those who had not (p = 0.11). Furthermore, a significant association was found between having no family history of communication and language disorders and the Dysfunctional Parent-Child Interaction subscale from the Parental Stress Index (U = -2.079, p = 0.038). These findings highlight the relevance of previous experience in EI to build family resilience as resilient parents are more likely to be actively involved in their children's education and create a supportive environment. Thus, promoting resilience in educational settings may have positive effects on children's and families' quality of life during the EI process.

The Effect of Acute Intense Exercise on Activity of Antioxidant Enzymes in Smokers and Non-Smokers.

Acute intense exercise causes significant oxidative stress and consequently an increase in total antioxidant capacity; however, the mechanisms and combined effects of intense exercise and smoking on oxidative stress among active and non-active smokers are not clear. The aim of this study was to investigate the effect of acute intense exercise on antioxidant enzyme activity responses in active and non-active individuals exposed to cigarette smoke. The study included 40 subjects who were equally classified as: smokers that did exercise (SE), smokers that did not do exercise (SnE), non-smokers that did exercise (NSE), and non-smokers that did not do exercise (NSnE). The adjusted Astrand test was used to exhaust the subjects. Salivary enzymes of peroxidase (POX), catalase (CAT), and superoxide dismutase (SOD) were measured, by spectrophotometry methods, at 3 different time points: pre-test (TP1), post-test (TP2), and one hour after finishing the test (TP3). Significant (p < 0.05) group x time interactions were found for the three enzymes. Salivary POX, CAT and SOD increased in all groups from TP1 to TP2 and decreased from TP2 to TP3. Only the NSE showed a significant difference between TP1 to TP3 in POX and SOD by +0.011 ± 0.007 and +0.075 ± 0.020 (U/mL), respectively. The NSE showed significantly higher activity of POX, CAT and SOD in TP2 compared to the other groups. Furthermore, NSE and NSnE had higher activity of POX, CAT and SOD in TP1 and TP3 (p < 0.05) compared with SE and SnE. Only in the NSnE, were no differences observed in CAT compared with SE and SnE in TP3. These results showed that the antioxidant activity at rest and in the recovery time after the acute intense exercise was lower in SE and SnE compared with NSE and NSnE, suggesting that smoking habit may reduce the ameliorating effect of regular physical activity on acute exercise-induced oxidative stress.

Balance training reduces fear of falling and improves dynamic balance and isometric strength in institutionalised older people: a randomised trial.

QUESTION: What is the effect of a balance training protocol with the Biodex Balance System in institutionalised older people with fear of falling? DESIGN: Randomised controlled trial with concealed allocation and assessor blinding. PARTICIPANTS: Forty older people who lived in a nursing home and had fear of falling. INTERVENTION: The experimental group completed a 12-week balance training protocol based on balancing/rebalancing training with the Biodex Balance System, with two sessions per week. During the training period, participants in both groups received the same multidisciplinary care (such as physiotherapy, occupational therapy and nursing) that they usually received in the nursing home. OUTCOME MEASURES: The primary outcome was fear of falling (Falls Efficacy Scale International questionnaire). Secondary outcomes were dynamic balance (Fall Risk Test) and isometric strength (torque of knee flexor and extensor isometric strength measured with an isokinetic dynamometer). Outcome measures were taken before and after the training program protocol. RESULTS: Compared to the control group, the exercise group had significantly greater improvements at 12 weeks in fear of falling (by 8 points, 95% CI 4 to 12), in dynamic balance (by 2 degrees, 95% CI 1 to 3), and in isometric strength of the knee flexors (by 7Nm, 95% CI 3 to 11) and knee extensors (by 7Nm, 95% CI 1 to 13). CONCLUSION: The training program was feasible and effective in reducing fear of falling and improving dynamic balance and isometric strength in institutionalised older people with fear of falling.
