The long-term cardiorespiratory function in burn-injured children can be jeopardized due to complications brought on by the injury. This study sought to assess the cardio-respiratory responses to maximal exercise in children who sustained a burn injury and explore the relationships among cardio-respiratory response, physical activity levels (PALs), and health-related quality of life (HRQL). Forty-five burn-injured children (age:13.89±2.43 years; duration since burn-injury: 3.13±0.93 years) and 52 age- and gender-matched healthy children (14.15±2.27 years) participated in this study. Both cohorts were evaluated for the maximal exercise capacity [defined by peak oxygen uptake (VO2peak), maximum heart rate (HRmax), minute ventilation (VE), ventilatory equivalent (VEq), respiratory rate (RR), and respiratory exchange ratio (RER)], PALs, and HRQL. The burn-injured children had significantly lower VO2peak (P=.0001) and VE (P=.003) and higher VEq (P<.0001) and RR (P=.007) than their healthy controls, indicating less efficient cardio-respiratory capacity. However, the HRmax (P=.092) and RER (P=.251) were similar. The burn-injured children reported significantly lower PALs (P=.014) and HRQL (P<.0001). The PALs [r (95%CI) = 0.411 (0.132 to 0.624); P = .005] and HRQL [r (95%CI) = 0.536 (0.284 to 0.712); P = .0001] were significantly correlated with the cardio-respiratory capacity represented by VO2peak in burn-injured group. The variations in VO2peak explained ⁓ 17% and 28.7% of the variations in PALs and HRQL, respectively. In conclusion, the cardio-respiratory efficiency of the burn-injured children may remain limited, even up to a few years following the injury. The limited cardio-respiratory capacity account in part for the reduced PALs and HRQL.

BACKGROUND: Burns to the thorax are at high risk for long-term pulmonary complications due to chest muscle contractures and chronic inflammation in both adolescents and young adults. Few studies have investigated the effects of arm cycling exercise in those individuals. For that reason, this study examined pulmonary function, functional capacity, and quality of life (QOL) in adolescents with thoracic burns subsequent to 2-month arm cycling exercise programme. METHODS: A single-blinded, two-month randomized prospective controlled study was carried out between July 2019 and March 2020 on thirty adolescents with chest burns aged 11-17 years. They were randomized into two equal groups (n = 15), traditional physiotherapy programme (control group), and arm cycling exercise plus traditonal physiotherapy (arm cycling exercise group) for 2 consecutive months. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), six-minute walk test (6MWT), and Pediatric Quality of Life Inventory (PedsQL) were measured in both groups at baseline and after 2-month after intervention. RESULTS: No statistical significance was detected at baseline between control and arm cycling exercise groups (FVC, p = 0.903, FEV1, p = 0.835, 6MWT, p = 0.817, and PedsQL, p = 0.612). 2 months after intervention showed statistical improvements in the arm cycling exercise group in all measures (FVC, p = 0.001, FEV1, p < 0.0001, 6MWT, p = 0.001, and PedsQL, p = 0.001) however, the control group showed statistical improvements in FVC, p = 0.044 and FEV1, p = 0.024 with non-statistically significant changes in 6MWT, p = 0.145 and PedsQL, p = 0.067. The arm cycling exercise group showed greater improvements than control group in the outcome measures (FVC, p = 0.034, FEV1, p < 0.017, 6MWT, p = 0.037, and PedsQL, p = 0.021). CONCLUSIONS: This prospective study clearly demonstrated positive and beneficial influences of two-month arm cycling exercise in the optimization of pulmonary functions, functional performance, and QOL in adolescents suffering from chest burns and thereby eliminating post-burn complications.

BACKGROUND: Recently, poor cardiorespiratory fitness (CRF) has been postulated as an adverse health outcome related to poor sleep quality. However, studies investigating the relationship between CRF and a subjective sleep quality index are scarce. Thus, the current study aimed to investigate the association between CRF and the Pittsburgh Sleep Quality Index (PSQI) in apparently healthy people. The secondary aim was to investigate the association between reported physical activity (PA) and PSQI. METHODS: Thirty-three healthy male participants volunteered to participate. CRF (VO2PEAK) was measured via cardiopulmonary exercise testing on a treadmill. A short form of the International Physical Activity Questionnaire (IPAQ) was used to measure PA, and PSQI was used for the sleep quality index. RESULTS: There was no correlation between CRF and PSQI total score or any component of the PSQI. There was a significant inverse correlation between IPAQ and PSQI total score (r = -0.36, p = 0.04). Categorical data analysis of the two questionnaires revealed that 42.4% of the participants who reported low physical activity also had poor sleep quality. CONCLUSIONS: The current study showed no association between CRF and the subjective sleep quality index but demonstrated a moderate inverse association between reported PA and subjective sleep quality index. The findings suggest that the more reported PA, the better the overall sleep quality.

BACKGROUND AND AIMS: Stroke is a leading cause of death and disability worldwide. However, our knowledge of the incidence of stroke for Saudi Arabian population is not known. Thus, we aimed to determine the pooled annual incidence of stroke in Saudi Arabia. We conducted a comprehensive literature search of PubMed, Web of Science, and SCOPUS, without language or publication year limits. Outcomes of interest were stroke incidence rate for both first and recurrent. A total of five studies met the inclusion criteria for this review. The pooled annual incidence of stroke in Saudi Arabia was 0.029% (95% CI: 0.015 to 0.047) equivalent of 29 strokes per 100,000 people annually (95% CI: 15 to 47). CONCLUSION: The findings indicate that there are 29 stroke cases for every 100,000 people annually for individuals residing Saudi Arabia. Our values were lower than those of other high-income countries. Establishing a nationwide stroke registry is warranted for monitoring and improving healthcare services provided to stroke survivors.
