Determinants of Health-Related Quality of Life in Chronic Chikungunya Disease in Guadeloupe.

Chronic chikungunya disease is associated with a poor quality of life and a variety of symptoms, not restricted to the musculoskeletal system. Patients with chronic chikungunya disease in Guadeloupe were evaluated in order to identify the main factors determining the quality of life. Patients were followed up at a mean of 36 months after chikungunya infection, undergoing detailed clinical examination for musculoskeletal involvement, with assessment of subjective symptoms and the impact on mood, physical activity, and quality of life (SF12). Patients had extensive musculoskeletal involvement shown by tenderness in 9 ± 4 joints and stiffness in 5 ± 4 joints. SF12 physical and mental component scores showed a poor health-related quality of life. Measures of joint pain, stiffness, and inflammation contributed to impaired quality of life scores. In addition, fatigue and interrupted sleep appeared to be important predictors for physical aspects of quality of life. The emergence of anxiodepressive syndromes post-chikungunya infection was associated with both physical and mental component scores of SF12. These data confirm that musculoskeletal symptoms are not the only determinants of quality of life in chronic chikungunya disease. Follow-up of patients should include assessment and management of fatigue, poor sleep quality, and anxiodepressive syndromes.

Improvement of Executive Function after Short-Term Administration of an Antioxidants Mix Containing Bacopa, Lycopene, Astaxanthin and Vitamin B12: The BLAtwelve Study.

During the last few years increasing interest has been focused on antioxidants as potentially useful agents in the prevention of the onset and progression of cognitive dysfunction. In this randomized, double-blind, controlled, parallel arm study, the effects of daily consumption of an antioxidant mix on cognitive function in healthy older adults were evaluated. After a 1 week run-in period, 80 subjects aged 60 years or more, and with no evidence of cognitive dysfunction, were randomly allocated to a mix of four bioactive compounds (bacopa, lycopene, astaxanthin, and vitamin B12) or matched placebo, taken orally once a day for 8 weeks. The primary objective of the study was to evaluate the changes in trial making test (TMT) scores from baseline to 8 weeks of treatment, analyzed in the following hierarchical order: TMT-B, TMT-A, and TMT-B minus TMT-A. TMT-B increased in the control group (+3.46 s) and decreased in the active group (-17.63 s). The treatment difference was -21.01 s in favor of the active group (95% C.I. -26.80 to -15.2, p < 0.0001). The decrease in TMT-A was significantly higher in the active group (-6.86 s) than in the control group (-0.37 s). TMT-B minus TMT-A increased in the control group (+3.84 s) and decreased in the active group (-10.46 s). The increase in letter fluency in the verbal fluency test (VFT) was also significantly higher in the active group and statistically significant (+5.28 vs. +1.07 words; p < 0.001). Our findings provide encouraging evidence that regular dietary supplementation with bacopa, lycopene, astaxanthin, and vitamin B12 may be an effective dietary approach for counteracting cognitive changes associated with brain aging.

Influences of 432 Hz Music on the Perception of Anxiety during Endodontic Treatment: A Randomized Controlled Clinical Trial.

INTRODUCTION: Patients undergoing endodontic therapy often have severe perioperative and intraoperative anxiety, which may lead to increased perceptions of pain and vital sign instability throughout treatment. The purpose of this study was to test the influences of music, as a nonpharmacologic adjuvant, in terms of significant changes for systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) before, during, and after endodontic treatment in a population with different levels of anxiety assessed with the Corah Dental Anxiety Scale. METHODS: A total of 100 patients were recruited in the present study; before starting the endodontic treatment, the interviewer administered the Corah Dental Anxiety Scale to the participants to assess the baseline level of anxiety. Patients were randomly divided into 2 groups: the first one listened to the music and the second one did not. Before, during, and after the endodontic procedures, the vital signs (diastolic and systolic blood pressure and heart rate) were recorded. Results were collected and statistically analyzed. RESULTS: Direct contrasts between patients listening or not listening to music showed that all the measured vital signs decreased considering the overall period (during and after the canal therapy) in the group of patients listening to music (P < .05). CONCLUSIONS: This study shows the effects of music therapy on vital values and on subjective perception of anxiety during endodontic therapy. Music and medicine always work together; the soothing effects of sounds and musical frequencies make this union an extraordinary tool of synergistic care. Music therapy is a valid nonpharmacologic adjuvant to anxiety perception in endodontic therapies.
