Internet gaming disorder, psychological distress, and insomnia in adolescent students and their siblings: An actor-partner interdependence model approach
Get PDFBackground: Associations between internet gaming disorder (IGD), psychological distress, and sleep have been reported. However, little is known whether such associations exist across siblings; that is, whether adolescents’ IGD symptomatology may impact their siblings’ psychological distress and sleep. This study aimed to examine whether siblings' IGD symptoms may relate to depressive, anxiety symptoms or sleep quality among each other. Methods: Using a cross-sectional design with two-stage cluster sampling, 320 dyads of adolescent students and their siblings participated in the study. Each dyad completed the Internet Gaming Disorder Scale-Short Form (IGDS-SF9), the Depression Anxiety Stress Scale-21 (DASS-21), and the Insomnia Severity Index (ISI). The actor–partner interdependence model (APIM) was applied to examine relationships between IGD, psychological well-being, and insomnia severity in the dyadic data. Results: Actor effects of IGDS-SF9 scores on depression, anxiety, stress, and insomnia severity were significant in both adolescents (e.g., adolescents’ IGDS-SF9 scores on their depression scores) and their siblings (e.g., IGDS-SF9 scores of adolescents’ siblings’ scores on their depression scores). Partner effects of IGDS-SF9 scores on depression, anxiety, stress, and insomnia severity were significant in both adolescents (e.g., adolescents’ IGDS-SF9 scores on their siblings’ depression scores) and their siblings (e.g., IGDS-SF9 scores of adolescents’ siblings on adolescents’ depression scores). Conclusions: The present study demonstrated that adolescent students and their siblings had mutual impacts of IGD on psychological health and sleep. Thus, healthcare providers may consider involving siblings when they design programs reducing IGD-related problems or improving psychological health and sleep for adolescents. © 2020 The Author(s
Effects of a health education program to promote healthy lifestyle and glycemic control in patients with type 2 diabetes: A randomized controlled trial
Get PDFBackground: Type 2 diabetes mellitus (T2DM) is a common chronic disease with an increase in prevalence within developing countries. The aim of this study was to determine the efficacy of a structured educational program for improving lifestyle and health-related measures in Iranians with T2DM. Methods: A randomized controlled trial was conducted in 80 participants with T2DM who were randomly assigned to either the intervention or a control group. A demographic questionnaire along with the Health Promoting Lifestyle Profile-II and related laboratory tests were used to assess the efficacy of the program. The intervention consisted of six educational sessions held over 45 days. The control group received routine diabetic care at the clinic. Three months after the intervention, participants completed the measures again. Within-group and between-group comparisons were then made. Results: All subscales of lifestyle measure improved in the intervention group, whereas only the nutrition domain improved in the control group. After adjusting for baseline differences, physical activity and nutrition domains showed the greatest improvement in the intervention group compared to controls. All clinical measures were also significantly improved within intervention group from baseline to follow-up (p < 0.001), whereas HbA1c, fasting blood glucose, HDL, triglyceride, cholesterol, and weight also changed significantly in the control group. The frequency of HbA1c < 7% was increased from 27.5% at baseline to 37.5% at follow-up (10%) in the intervention group compared to only a 5% increase in the control group. Conclusion: This educational health program significantly improved lifestyle changes and health-related clinical characteristics in persons with T2DM, compared to routine diabetic care in Iran. Further research is needed to better understand the usefulness of such programs in diabetics and other medical conditions among those in different cultural settings. © 2020 Primary Care Diabetes Europ
Nanocluster structure of pistacia atlantica subsp. Kurdica turpentine and its antibacterial effects
Get PDFBackground: Medicinal herbs such as Pistacia Atlantica (P. Atlantica) subsp. Kurdica have antimicrobial effects. The present study is aimed to investigate the nanocluster structure of P. atlantica subsp. Kurdica turpentine and its composing elements and antibacterial effect. Methods: 100 μl ethanol was used to dissolve oily turpentine. 2, 2.2, 2.4, and 2.6 μg/μl of turpentine were used for investigating the antibacterial effects using disk and well diffusion methods. Elemental and nanocluster structure analyses were performed by Energy-Dispersive X-Ray Microa-nalysis (EDXMA) and Field Emission (FE)-scanning electron. Two-way analysis of variance (ANOVA) and Bonferroni test were used for data analysis (p ≤ 0.001). Results and Discussion: EDXMA elemental analysis of turpentine included: Zinc (Zn), Magnesi-um (Mg), Fluorine (F), Oxygen (O), Silicon (Si), Carbon (C), and Argentum (Ag). A topography image of the turpentine showed a nanocluster surface with bright clusters in the background. The largest diameters of the growth inhibition zones (24.67 ± 0.58 mm in the disk diffusion and 23.67 ± 1.53 mm in the well diffusion) that were created by turpentine were observed against S. aureus ATCC 25923 at the concentration of 2.6 μg/μl. The diameter of the inhibition zone around bacterial growth had a direct relationship with turpentine concentration (p ≤ 0.001). Conclusion: The nanocluster structure of turpentine and its composed elements were detected in this research. Moreover, the antibacterial effects of turpentine were proved. Herbal substances are widely used in medical applications. Different elements of P. atlantica subsp. Kurdica turpentine can be used as antibacterial agents, but more in-vitro and in-vivo studies should be performed in this field
A critical review of state-of-the-art electrocoagulation technique applied to COD-rich industrial wastewaters

Extensive research efforts implementing EC technologyhavebeenexecutedoverthelastdecadetotreatchemicaloxygendemand(COD)-richindustrialwastewaterswiththe aim to protect freshwater streams (e.g., rivers, lakes) from pollution. A comprehensive review of the available recent literature utilizingECtotreat wastewater withhighCODlevelsispresented.Inaddition,recommendationsareprovidedforfuturestudies to improve the EC technology and broaden its range of application. This review paper introduces some technologies which are often adopted for industrial wastewater treatment. Then, the EC process is compared with those techniques as a treatment for COD-richwastewater. The EC process is consideredasthe mostprivilegedtechnologybydifferent researchgroupsowingtoits ability to deal with abundant volumes of wastewater. After, the application of EC as a single and combined treatment for CODrichwastewatersisthoroughlyreviewed.Finally,thisreviewattemptstohighlightthepotentialsandlimitationsofEC.Relatedto the EC process in batch operation mode, the best operational conditions are found at 10 V and 60 min of voltage and reaction time, respectively. These last values guarantee high COD removal efficiencies of > 90%. This review also concludes that considerably large operation costs of the EC process appears to be the serious drawback and rendersit asanunfeasibleapproach for handling of COD rich wastewaters. In the end, this review has attempted to highlights the potential and limitation of EC and suggests that vast notably research in the field of continuous flow EC system is essential to introduce this technology as a convincing wastewater technology
