[Q]: We investigated the effects of pulsed ultrasound on swelling, muscle soreness perception, relaxed-elbow extension angle, and muscular strength.', 'Eight sets of concentric and eccentric actions induced delayed-onset muscle soreness of the elbow flexors. Group 1 received 20% pulsed ultrasound treatments (1-MHz, 7 minutes, 1.5 W/ cm(2) temporal peak intensity) twice a day immediately after postexercise assessments and at 3, 24, 27, 48, 51, 72, and 75 hours postexercise. Group 2 received sham treatments immediately after postexercise assessments and at 3,27, 51, and 75 hours postexercise and true treatments of pulsed ultrasound at 24, 48, and 72 hours postexercise. Group 3 received sham treatments of no ultrasonic output immediately after postexercise assessments and at 3, 24, 27, 48, 51, 72, and 75 hours postexercise.', 'Thirty-six college-age females.', 'We recorded upper-arm circumference, perceived soreness, relaxed-elbow extension angle, and elbow-flexion strength before (pretest), immediately postexercise, and at 24, 48, 72, and 96 hours postexercise.', 'We noted differences over time but no treatment effect between groups or interactions between time and group for upper-arm circumference, perceived soreness, relaxed-elbow extension angle, or elbow-flexion strength.
[A]: Does pulsed ultrasound fail to diminish delayed-onset muscle soreness symptoms?


[Q]: We describe a three-year experience with patients with dementia.', 'clinical, cognitive and functional evaluation was performed by a multidisciplinary team for persons above 60 years. Mortality was assessed after three years.', "Mini-Mental State Examination (MMSE) (n=2,074) was 15.7 (8.4). Male patients MMSE (n=758) was 15.6 (8.3) and female's (n=1315) was 15.8 (8.3). Instrumental Activities of Daily Living Scale (n=2023) was 16.5 (7.6); females (n=1277) was 16.9 (7.2) and males (n=745) was 15.7(8.2). From these patients, 12.6% (n=209) died within three years. Baseline cognition of patients still alive was higher (p<0.001) than MMSE of those who died [MMSE=16.3 (8.1) vs. 10.6 (7.6)]. Mortality rate decreased 6% (IR=0.94) for each additional point on MMSE. Higher functional status decreases the mortality rate approximately 11% (IR=0.89) independently of age, gender, and education.
[A]: Is lower mortality rate in people with dementia associated with better cognitive and functional performance in an outpatient cohort?


[Q]: Lung inflation causes cardiovascular suppression via an increase in intrathoracic pressure and neural mechanisms. To examine the mechanisms involved, we mea-sured the heart rate (HR) and arterial blood pressure (AP) responses to lung inflation before and after spraying the bronchi with lidocaine to suppress airway reflex. Thirty women participated in the study. One group (n = 20, Group BT) had their tracheas intubated by using double-lumen tubes. The other group (n = 10, Group TT) received an ordinary endotracheal tube. They were all studied under general anesthesia by using nitrous oxide, isoflurane, and muscle relaxation after a thiopental induction. In each patient, airway pressure was increased for 3 s, and changes in HR and AP were measured. Lung inflation was repeated after 5 mL of 4% lidocaine had been sprayed into the main bronchi unilaterally in Group BT or bilaterally in Group TT. There were no significant differences in cardiovascular responses between left and right lung inflation with the pressure at 20 and 30 cm H(2)O. Both lungs inflated at 20 cm H(2)O caused an increase in HR with a significantly greater decrease in AP than with unilateral inflation. Anesthesia of the bronchi abolished the HR increase, but not the AP decrease. Lung inflation at 30 cm H(2)O caused significant decreases in HR and AP which were not affected with topical anesthesia. These results indicate that the cardiovascular responses elicited by lung inflation in anesthetized humans are predominantly the direct effect of the increase in intrathoracic pressure, although sympathetic afferent activity induced via stimulation of mechanoreceptors in the airways contributes.
[A]:
Does localized airway anesthesia with lidocaine partially suppress cardiovascular responses To lung inflation?
