The frequency domain (low frequency, high frequency and sympathovagal balance) and symbolic analysis (0V, 1V and 2V patterns) of heart rate variability were obtained before and until one hour after the interventions.
RESULTS: After the resistance exercise and control sessions, similar increases were observed in the consecutive heartbeat intervals (control: 720.8 +/- 28.6 vs. 790.9 +/- 34.4 ms; resistance exercise: Belnacasan ic50 712.9 +/- 30.1 vs. 756.8 +/- 37.9 ms; p<0.05) and in the pattern of the symbolic analysis with no variation (0V) (control: 25.1 +/- 3.5 vs. 33.4 +/- 4.1%; resistance exercise: 26.1 +/- 3.2 vs. 29.7 +/- 3.5%; p<0.05) until 50 min
after both interventions. The pattern of two variations (2V) decreased similarly (control: 11.2 +/- 2.1 vs. 8.3 +/- 2.1%; resistance exercise: 9.5 +/- 1.7 vs. 7.8 +/- 1.7%; p<0.05). In contrast, the pattern of one variation (1V), the low and high frequency bands and sympathovagal
balance Etomoxir did not change after the interventions (p>0.05).
CONCLUSION: A single bout of resistance exercise did not alter cardiac autonomic modulation in patients with peripheral artery disease.”
“Objective: To determine the validity of dichotic multiple frequencies auditory steady-state responses (ASSR) as a hearing screening technique versus using distortion product otoacoustic emissions (DPOAEs) among high-risk neonates.
Methods: A cross sectional study was performed on 118 high-risk neonates by means of dichotic multiple frequencies ASSR and DPOAE for hearing screening. DPOAE results were used as the standard for hearing screening in parallel with ASSR. Dichotic
multiple frequencies ASSR results were analyzed by means of F-value of less or greater than 0.05 criteria as a pass-fail for the responses. Dichotic multiple ASSR hearing screening technique was considered in two intensity levels at 40 and 70 dB HL The ASSRs thresholds were measured in high risk neonates with and without hearing deficits as determined by DPOAES. The results of ASSR and DPOAE were compared to be gathered by contingency table in order to obtain sensitivity, FRAX597 in vivo specificity and other different statistical values. Average performing times for the tests were analyzed.
Results: The specificity of dichotic multiple ASSR was 92.6%, 93.8% and the sensitivity was 71.6%, 62.2% at the 70 and 40 dB hearing levels, respectively. Mean ASSR thresholds for normal-hearing infants at an average corrected age of 6 days were 32.2 +/- 12.2, 29.8 +/- 10.2, 26.2 +/- 11.4 and 30.4 +/- 10.8 dB HL for 0.5, 1, 2 and 4 kHz, respectively. The average times for performing the tests were 18.7 and 32.9 min respectively.
Conclusions: ASSR with this special paradigm is a fairly desirable method for hearing screening of high-risk neonates.
