METHODS: Ten previously sedentary female subjects diagnosed with Panic Disorder performed 36 sessions of aerobic exercise (at 70 to 75% of VO2max), 3 times per week during 12 weeks. A cardiopulmonary evaluation (ergospirometry test) was used to set the intensity of training as well as to establish baseline and post-training VO2max parameters. The assessment of anxiety symptoms was performed at baseline, at the end of the 6th and 12th weeks, using the Trait Anxiety Inventory (STAI-T) and State Anxiety Inventory (STAI-S), and the Subjective Units of Distress Scale (SUDS) questionnaires. One-way ANOVA for repeated measurements (at 3 moments: Baseline, 6th week (mid-training) and 12th week (post-training) was used to compare the evolution of the questionnaires; the Bonferroni post hoc test was applied to identify differences between moments. A dependent t-test was performed for measures of VO2max. RESULTS: Compared to baseline, (a) STAI-T showed significant anxiety reductions at mid- and post-training moments; (b) STAI-S and SUDS recorded anxiety reductions only at Post-training; (c) VO2max showed a significant improvement at Post-training.

METHODS: Eight subjects were randomly submitted to two situations, as follows: a static stretch protocol and 20 minutes at rest. The stretch protocol consisted of two sets of 30 seconds of static stretch of the chest muscles with a 40 second of interval between them. After 48 hours, the procedures were reversed so that all the subjects should were submitted to the two situations. The values of heart rate variability were measured before and after the experimental and control situation (stretch vs. rest). We registered the following cardiac variables: root mean square of standard deviation (rMSSD), the number of pairs of successive beats that differ by more than 50 ms (pNN50), low frequency (LF) and high frequency (HF). The Shapiro-Wilk and the paired Student's test were used for statistical analysis; a critical level of significance of p 0.05) were found (stretching vs. control) to the RMSSD, pNN50, LF and HF indices. However, although no statistical differences were observed, the figures show large changes on mean values, suggesting an unclear effect on the sympathetic-vagal modulation. CONCLUSION: The present results suggest that a low intensity (motion range until discomfort point) and volume (1 minute) of static stretching does not significantly affect the acute sympathetic-vagal control in trained men. Because the protocol did not show differences regarding the studied variables, we suggest that there is not a sufficient level of physiological basis to perform this type of exercise in a traditional pre-exercise setting, if the purpose is obtain gains in physical performance.","PeriodicalId":31471,"journal":{"name":"Medical Express","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71189777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHOD: Cross-sectional observational study, without intervention, of 126 postmenopausal women (60.3 ± 3.2 years; body mass index = 27.6 ± 4.7 kg/m2). Two devices were used for the independent assessments of static balance: (a) Static postural balance assessment (posturography) was performed on a force platform (AccuSway Plus); (b) static evaluation was performed on the Balance Master®System. The variables studied in the two devices, were: (i) the Mean Velocity of the Center of Pressure Displacement in all directions (Vavg or Mean Firm), (ii) the Anteroposterior (Mean-Y) and (iii) the Mediolateral (Mean-X) Centers of Pressure Displacement. The Spearman correlation coefficient was calculated to measure the correlation of the variables of balance obtained with the two different devices. RESULTS: Significant correlations were obtained when the relationships between both variables were described by fitting multiple linear regression models. There was an association between the mean velocity of center of pressure displacement in both devices, with eyes open (r = 0.21) and eyes closed (r = 0.47). In the eyes open condition, Vavg increased, on average, 0.26 units, while Mean Firm increased 1.0 unit; in the Mean-Firm; in eyes closed condition, Vavg increased, on average, 1.27 units, while Mean-Firm increased by 1,0 unit.

METHOD: 119 patients who underwent percutaneous nephrolithotomy were prospectively evaluated between February 2012 and August 2014. Using thin cuts, the highest single-energy computed tomography attenuation value within a pixel was measured for each stone. Data regarding age and gender were assessed before surgery. The extracted stones were analyzed using infrared spectrophotometry. RESULTS: By receiver operating characteristics analysis, a cutoff value of 1548 Hounsfield Unit and an age of 42.5 years were used to determine the likelihood of a stone being composed of calcium oxalate monohydrate. A higher Hounsfield Unit value and increased age augmented the chances of a stone being composed of calcium oxalate monohydrate. In general, females had a greater likelihood of harboring calcium oxalate monohydrate stones than males.

In mature infants, the ductus arteriosus closes after birth. Patent ductus arteriosus occurs in 70% of preterm infants with a birth weight < 1,000 grams. Failure of the ductus arteriosus to close has been associated with intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia, periventricular leukomalacia, renal failure, and persistent pulmonary hypertension. The drugs used to treat the patent ductus arteriosus are ibuprofen and indomethacin which are potent non-selective inhibitors of cyclo-oxygenase (COX) and therefore inhibit prostaglandin E2 synthesis. Prostaglandin E2 relaxes smooth muscle and tends to inhibit the closure of the patent ductus arteriosus. Intravenous ibuprofen and indomethacin inhibit prostaglandin E2 synthesis and thereby close the patent ductus arteriosus with similar efficacy. Indomethacin reduces the blood flow velocity in kidneys, intestine and brain. Ibuprofen has less effect on blood flow velocity in these organs. There is a significant increase in serum creatinine after indomethacin administration but not after ibuprofen and infants treated with ibuprofen have higher creatinine clearance. Oliguria (urine output < 1 ml/kg/h) occurs more frequently with indomethacin than with ibuprofen. Indomethacin requires furosemide for urine output more often than ibuprofen. Ibuprofen reduces the risk of necrotizing enterocolitis and transient renal insufficiency and it is the drug of choice for closing the patent ductus arteriosus. Ibuprofen and indomethacin may be administered orally. In conclusion, intravenous ibuprofen and indomethacin close the patent ductus arteriosus at the same rate, but indomethacin is more toxic than ibuprofen.","PeriodicalId":31471,"journal":{"name":"Medical Express","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71189754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is not known whether a goal-directed protocol guided by tightly controlled hemodynamic variables, including pulmonary artery catheter, will safely improve clinical renal dysfunction markers in these patients when compared to a less invasive approach. METHODS: Pilot, randomized clinical trial aimed at patients with known heart failure, low cardiac output syndrome and renal dysfunction with less than 48 hours from onset. We randomized two groups: (a) goal-directed therapy monitored with pulmonary artery catheter and (b) conventional therapy with central venous catheter. Hemodynamic parameters, venous oxygen saturation, serum lactate, fluid repositions and vasoactive drugs were compared considering renal function improvement after 72 hours as the primary study endpoint. We included 15 goal-directed therapy and 16 conventional therapy patients. The study has assessed patients on baseline looking for significant improvement at 72 hours of the following parameters in the goal-directed therapy and conventional therapy groups: urine output, serum creatinine, venous oxygen saturation and serum lactate. RESULTS: Baseline characteristics were similar in both groups. In the first 24 hours there was a lower volume of fluid reposition in the goal-directed therapy group, although 72 hours later such reposition was equivalent. The use of inotropic agents was similar between groups. There was an improvement to the renal function and the hemodynamic parameter in both study groups.

It has been claimed that cardiovascular responses are related to the muscle mass involved during execution, but some studies do not confirm these findings. We analyzed the behavior of heart rate, systolic/diastolic blood pressure, and double product in middle-aged women while performing exercises for two muscle groups with different volumes: elbow flexors (small mass) and knee extensors (large mass). METHOD: The study sample comprised eight women physically active for at least 6 months. The experimental procedure was performed in 3 sessions. In the first session, the characterization of the sample and a 10 repetition maximum (10RM) test were conducted. In the second, participants performed a warm up and then (depending on randomization), either the elbow flexion or the knee extension exercises in 3 series of 10 repeats. In the third session, participants performed the alternate exercise, folllowing the same procedures. Systolic and diastolic pressures and heart rate were measured 5 minutes before warm up and at the end of each series. RESULTS: No difference was observed in the acute cardiovascular responses for exercises involving the two different muscle mass volumes in normotensive women above age 45 years. CONCLUSION: The cardiovascular response is not affected by the exercised muscular mass in this specific population. Further studies should examine these variables in different conditions such as weather, climate and other populations.","PeriodicalId":31471,"journal":{"name":"Medical Express","volume":"3 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71189881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
