The effectiveness of adolescent-oriented mindfulness training on academic burnout and social anxiety symptoms in students: experimental research.

The aim of this study was to investigate the effectiveness of adolescent-oriented mindfulness training on academic burnout and social anxiety symptoms in students. The current study was a semi-experimental type with a pretest-posttest design with a control group with the measurement at baseline after the intervention and a 3-month follow-up. The statistical population included all high school students with symptoms of social anxiety who were studying in Tehran in the academic year 2022. Among the students, 100 students were selected as a sample by purpose-based sampling and randomly assigned to two experimental and control groups (50 people). The tools of this research were a researcher-made demographic questionnaire, social anxiety questionnaire, academic burnout questionnaire, and adolescent-oriented mindfulness protocol. Data analysis was performed using analysis of variance with repeated measures. The results showed that adolescent-oriented mindfulness training had a significant effect on reducing academic burnout and social anxiety symptoms of students (P<0.001). Based on the findings of the research, it can be said that adolescent-oriented mindfulness training is effective in reducing academic burnout and social anxiety symptoms of students.

Phytochemistry and Biological Activities of Amburana cearensis (Allemão) ACSm.

Amburana cearensis (Allemão) ACSm. belongs to the Fabaceae family and occurs in the Brazilian semiarid, Argentina, Paraguay, Bolivia, and Peru. Numerous studies that portray its ethnobotany, use in popular medicine, chemical composition, and biological activities exist in the literature. This review aimed to provide an overview of the chemical composition, ethnopharmacology, and biological activities associated with A. cearensis and its isolated constituents. Information was collected from internet searches in the Scopus, Medline, PubMed, Google Scholar, and ScienceDirect databases were performed covering publications from 1997-2020. An ethnopharmacological literature analysis revealed that A. cearensis is used to treat a wide range of respiratory disorders in addition to intestinal, circulatory, and inflammatory problems. Coumarins, flavonoids, phenolic glycosides, phenolic acids, phenylpropanoid derivatives, and triterpenoids, among others, have been reported as active compounds, with High-Performance Liquid Chromatography (HPLC) being the main analytical technique used. The A. cearensis extracts and compounds presented several biological activities, including antimicrobial, antinociceptive, anti-inflammatory, antioxidant, neuroprotective, and myorelaxant activities, among others. This review provides a useful bibliography for future investigations and A. cearensis applications; however, future studies should focus on its toxic effects and the mechanisms of action of its extracts and isolated constituents to guide clinical applications.

Effect of inhalation aromatherapy with lavender essential oil on stress and vital signs in patients undergoing coronary artery bypass surgery: A single-blinded randomized clinical trial.

OBJECTIVES: At present, aromatherapy is used widely in medical research. This study aimed to investigate the effects of inhalation aromatherapy using lavender essential oil to reduce mental stress and improve the vital signs of patients after coronary artery bypass surgery (CABG). DESIGN: A single-blinded randomized controlled trial was conducted with 60 patients who had undergone CABG in a 2-day intervention that targeted stress reduction. PARTICIPANTS: Sixty subjects following coronary artery bypass surgery in two aromatherapy and control groups. SETTING: The study was conducted in Ekbatan Therapeutic and Educational Center, Hamadan, Iran, in 2013. INTERVENTIONS: On the second and third days after surgery, the aromatherapy group patients received two drops of 2% lavender essential oil for 20min and the control group received two drops of distilled water as a placebo. MAIN OUTCOME MEASURES: The primary outcome was mental stress, which was measured before and after the intervention using the DASS-21 questionnaire. The secondary outcomes were vital signs, including the heart rate, respiratory rate, and systolic and diastolic blood pressure, which were measured before and after the intervention. RESULTS: The individual characteristics of the aromatherapy and control groups were the same. There were no significant difference in the mean mental stress scores and vital signs of the aromatherapy and control groups on the second or third days after surgery. CONCLUSION: Inhalation aromatherapy with lavender essential oil had no significant effects on mental stress and vital signs in patients following CABG, except the systolic blood pressure.
