Abstract
Background: Insomnia is the most common sleep disorder that is associated with cortical hyperexcitability. Potentially transcranial direct current stimulation (tDCS) modifies the cortical state related to insomnia. Therefore, we hypothesized that by using tDCS the intensity of insomnia can be reduced, followed by improvement of the mood symptoms.
Methods: This study was an experimental design with a pre-test and post-test with a control group. The statistical sample included 32 females with chronic insomnia that were randomly divided into an experimental group (active stimulation) and a control group (sham stimulation). Transcranial direct current with an intensity of 2 mA was applied for 30 minutes during 12 sessions (three times in the week) in the active stimulation group. In this protocol, anodal stimulation of left Superior temporal gyrus (STG) and cathodal stimulation of right dorsolateral prefrontal cortex (DLPFC) and left secondary motor cortex (SMA). In the control group, sham stimulation was performed for 30 minutes during 12 sessions (three times in the week). The participants were evaluated before and after of the intervention using the Insomnia Severity Index (ISI) and Positive and Negative Affect Scale (PANAS).
Results: The findings of this research showed that the application of transcranial direct current stimulation was effective in reducing the severity of insomnia and improving positive and negative affect (P<0.001, F=19.87). The value of this effect (eta2) in the severity of insomnia, negative mood and positive mood is 0.64, 0.34 and 0.6 respectively.
Conclusion: The results of the present study showed that the implementation of our designed tDCS protocol for the treatment of insomnia, significantly reduced the intensity of insomnia in women with chronic insomnia and improved their mood symptoms.

Abstract
Background: Asthma is a chronic inflammatory disease of the airways. Various tests and questionnaires are designed to monitor the severity of asthma and help the therapist and the health system prescribe the best treatment to control it. This study was designed to compare two methods Asthma Control Questionnaires (ACQ) and Asthma Control test-child (ACT-CHILD) in children with asthma.
Methods: This descriptive cross-sectional study was conducted on 92 children with asthma referred to the Taleghani hospital, Gorgan, in 2022-2023. Patients were in a range of age 4-16 years. Asthma control was evaluated and compared by two methods ACT-CHILD and ACQ. ACT-CHILD included one version for 4-11-year patients completed by their parents and another one for 12-16 –year patients completed by the patients. The clinical symptoms, age, gender and the parents' records related to asthma were completed during the clinical interview. Data was analyzed using Chi-square and Spearman correlation tests. The degree of agreement between two questionnaires was determined using the Kappa coefficient.
Results: 84 children aged 4-11 years (91.3%) and 8 children aged 12-16 years (8.7%) were included in the study. According to the ACT-CHILD, 40.2% of children (n=37) had controlled asthma, 44.6% (n=41) had partially controlled asthma, and 15.2% (n=14) had uncontrolled asthma. Based on the ACQ, controlled asthma was observed in 18.5% (n=17), partially controlled asthma in 35.8% (n=33), and uncontrolled asthma in 45.7% (n=42) of children. Asthma control results based on two questionnaires were significantly different from each other (P<0.001). The agreement between the ACT-CHILD and ACQ methods in evaluating children's asthma was at a weak level (P=0.014, κ=0.157), however, a significant negative correlation was observed between the scores of the ACT-CHILD and ACQ questionnaires (r=-0.588, P>0.001) which after categorizing based on age group, this correlation was confirmed only in children aged 4-11 years (r=-0.627, P>0.001).
Conclusion: Our findings showed that there is a poor agreement between ACT-CHILD and ACQ results in the assessment of asthma control. Further studies are recommended.

The impact of high-intensity interval training (HIIT) combined with berberine supplementation on hematological parameters in middle-aged men with pre-diabetes: a randomized controlled trial

Volume 81, Issue 10 (January 2024)
Abstract
Background: Exercise programs can lead to different physiological adaptations, but the effects of low-volume, low-frequency HIIT protocols with varying interval structures have not been thoroughly investigated. This study aimed to explore the impact of HIIT with high compression (HC) and low compression (LC), with or without berberine (BBR) supplementation, on hematological parameters in pre-diabetic men.
Methods: This semi-experimental study was conducted between October and December 2021 at Mazandaran University. Fifty-four overweight/obese men with a mean age of 48.6±6.6 years, a body mass index of 30.7±7.3 kg/m², and a body fat percentage of 34.4±4.3% were randomly and equally divided into one of six groups: HC, LC, HC+BBR, LC+BBR, BBR, and control. The HC group (2:1 work-to-rest ratio) and LC group (1:1 work-to-rest ratio) underwent training programs comprising 2-4 sets of 8 exercises at an intensity of 80-95% of their maximum heart rate twice a week for 8 weeks. Hematological responses to Bruce's incremental exercise test were measured before and after the intervention. Data were analyzed using a two-way ANOVA with Bonferroni's post hoc test, with a significance level set at P<0.05.
Results: Baseline hematological indices showed no significant differences between pre-diabetic and non-diabetic groups (all, P>0.05). Following the 8-week intervention, there were significant decreases in white blood cells (WBCs) in the LC and LC+BBR groups, and in lymphocytes across all intervention groups except BBR (all, P<0.05). Additionally, hemoglobin and hematocrit levels showed significant reductions in the HC and HC+BBR groups (both, P<0.05). However, in response to Bruce's incremental exercise test, a significant decrease in WBCs was observed in the LC and LC+BBR groups, with reductions of 18% and 25%, respectively (both, P<0.05).
Conclusion: The LC protocol, even without berberine supplementation, seems to provide better immunological benefits and result in less hemolysis compared to the HC protocol, as evidenced by reductions in white blood cell counts.

Abstract
Background: Being sedentary due to internet addiction is a common public health problem that causes overweight and obesity. Novel methods are needed for weight control behaviors. This study aimed to determine effects of short-term (two weeks) and moderate-term (four weeks) of virtual reality (VR) exercise program with and without interval Nordic walking (INW) in adolescent boys on novel body composition and maximal oxygen uptake (VO2max) parameters; body adiposity index (BAI), abdominal volume index (AVI), conicity index (CI), waist-to-height ratio (WHtR), and a body shape index (ABSI).
Methods: In a semi-experimental trial during July to December 2023, 70 adolescent boys (age 14.8 years, body mass index (BMI)=24.4 kg/m2 and VO2max 38 ml/kg/min) with the Young IA tests score ranging over five, were selected from the city of Karaj and randomly was classified to VR, INW, VR+INW and control groups. Individual and combined exercise programs of VR and INW were performed (three session in week for 30 min) for two and or four weeks. The parameters were evaluated at the baseline and the follow up phases (two and four weeks after the interventions period) with a repeated measure ANOVA.
Results: According to Young's internet addiction test scores at the beginning of the study, there was no significant difference between the control and intervention groups (P≥0.05). It has been observed that internet addiction negatively affects cardiorespiratory fitness. When a 2-week intervention of VR exercises was implemented along with INW, the improvement in cardiorespiratory fitness (VO2max) was better than when VR exercises alone lasted for four weeks (P≤0.05). After four weeks of INW intervention, separately and in combination with VR, a significant improvement was observed in VO2max, WHtR and BAI values compared to the control group (P≤0.01).
Conclusion: Although improvement in cardiorespiratory fitness of boys with IA can be achieved by doing short and medium term INW, VR and INW+VR exercises, longer interventions, i.e., four weeks or more, cause more significant changes in the novel body composition.
