Effects of Different Durations of 9-Square Dance Exercise Versus Treadmill Exercise on the Physical Fitness and Quality of Life of Healthy Volunteers: A Pilot Randomized Controlled Trial

Objective: To evaluate the impact of 9-square dance exercise (9SDE) on physical fitness and quality of life compared to traditional treadmill exercise (TME). Materials and Methods: In total, 33 healthy volunteers (10 men, 23 women) were recruited and randomly assigned into three groups: 9 square dance exercise for 8 minutes (9SDE-8), 9 square dance exercise for 30 minutes (9SDE-30), or treadmill exercise (TME). Exercises were done three times a week for 12 weeks and physical fitness tests were performed for all the groups at weeks 0, 6, and 12. Participants were assessed using the European Quality of Life Measure 5 Domains and 5 Levels questionnaire (EQ-5D-5L). Results: Significant improvements in cardiorespiratory endurance, leg strength, and flexibility were demonstrated in the 9SDE-30 group (p<0.05). There was no significant difference in physical fitness between the 9SDE-30 and TME groups. The 9SDE-8 group showed a significant improvement in utility in the EQ-5D-5L questionnaire (p<0.05), while the TME group showed a significant improvement in directly evaluated health status (p<0.05). 9SDE-30 and TME showed similar improvements in cardiorespiratory endurance and leg strength. Conclusion: Considering its low-resource requirement and overall utility, coupled with its effectiveness in promoting cardiovascular fitness and leg strength, 9SDE represents a viable exercise alternative for those with limited time and resources

Scombroid Poisoning from Canned Tuna Ingestion

Fish allergy is well recognized, however scombroid poisoning or histamine fish poisoning, which exhibits identical clinical manifestations, is rarely diagnosed. We report the case of a 28-year-old female who, after eating tuna spaghetti, experienced a flushed face, generalized erythema, angioedema, shock and tachypnea requiring adrenaline, chlorpheniramine, ranitidine, and hydrocortisone injections. Her symptoms completely resolved within 3 hours. Her condition was diagnosed as scombroid poisoning based on temporality, normal serum tryptase levels (2.7 ng/mL) at 2.5 hours and at her baseline (2.5 ng/mL, 60 hours), as well as negative results on skin-prick test and re-challenging one can of the same branded-tuna orally. The revelant public health authorities were notified and a restaurant-visit was made, although the tuna can from which the patient’s dish was prepared had been discarded, hence a histamine analysis of the tuna was unavailable. This case underscores the need for awareness of scombroid poisoning and public interventions regarding food safety
