Creative dance can enhance proprioception in older adults

Aim. It has been shown by many authors that proprioception declines with age. However, few studies have examined the effects of exercise interventions on proprioception. The purpose of this study was to investigate the effects of a creative dance program on proprioception of older adults. Methods. Thirty-seven men and women between 55 and 80 years of age, who were not engaged in any exercise program for at least one year, were randomly assigned to an experimental (63.6±5.7 years) or a control group (65.3±7.6 years). The experimental group participated in a creative dance program for 12 weeks with a periodicity of 3 sessions of 90 minutes per week. Measures of knee kinesthesia, knee joint position sense and arm positioning were taken before and after the program. Results. After 12 weeks, knee joint position sense (P=0.005) knee kinesthesia (in flexion) (P=0.04), and arm positioning (P=0.008) significantly improved within the creative dance training group. At 12 weeks follow-up, arm positioning performance was significantly better for the creative dance group when compared with the control group (P=0.043). The control group did not show any significant improvement in proprioception. Conclusion. This study showed that a creative dance program emphasising body awareness can improve proprioception in older adults

Effect of preemptive analgesia with ibuprofen in the control of postoperative pain in dental implant surgeries : a randomized, triple-blind controlled clinical trial

Preemptive analgesia has as its basic principle the administration of analgesics before the onset of painful stimuli, in order to reduce or prevent postoperative pain, but this question is little explored in implantology. Thus, this study was conducted in order to evaluate the clinical efficacy of ibuprofen in pain prevention after unit implant surgery. For this triple-blind, parallel, placebo-controlled and randomized clinical trial, 54 insertion surgeries of unitary implants were performed. Two groups have received two different protocols 1 hour before surgery: Ibuprofen group (IBU) 600 mg of ibuprofen; and (2) placebo group (maize starch). The intensity of the pain was evaluated through the visual analogue scale (VAS) in 6 times (1, 6, 12, 24, 48 and 72 hours after the surgery). Patients were instructed to take 750 mg of paracetamol as rescue medication, if necessary. The occurrence and the intensity of pain were analyzed by means of an analysis of variance ANOVA with repeated measurements using the general linear model procedure. The IBU group had significantly lower VAS scores overall (IBU = 0.30, ± 0.57; placebo = 1.14, ± 1.07; p<0.001) and at all times in the intra, intergroup comparisons and time/group interaction than the placebo group (p<0.001). The use of rescue medication was significantly lower and the postoperative time was longer in the IBU group compared to placebo (p = 0.002). The single use of ibuprofen was found to be significantly superior in reducing pain after unit implant surgery compared to placebo

Isohyetal maps of daily maximum rainfall for different return periods for the Colombian Caribbean Region

In Colombia, daily maximum multiannual series are one of the main inputs for design streamflow calculation, which requires performing a rainfall frequency analysis that involves several prior steps: (a) requesting the datasets, (b) waiting for the information, (c) reviewing the datasets received for missing or data different from the requested variable, and (d) requesting the information once again if it is not correct. To tackle these setbacks, 318 rain gauges located in the Colombian Caribbean region were used to first evaluate whether or not the Gumbel distribution was indeed the most suitable by performing frequency analyses using three different distributions (Gumbel, Generalized Extreme Value (GEV), and Log-Pearson 3 (LP3)); secondly, to generate daily maximum isohyetal maps for return periods of 2, 5, 10, 20, 25, 50, and 100 years; and, lastly, to evaluate which interpolation method (IDW, spline, and ordinary kriging) works best in areas with a varying density of data points. GEV was most suitable in 47.2% of the rain gauges, while Gumbel, in spite of being widely used in Colombia, was only suitable in 34.3% of the cases. Regarding the interpolation method, better isohyetals were obtained with the IDW method. In general, the areal maximum daily rainfall estimated showed good agreement when compared to the true values. © 2019 by the authors

Preemptive analgesia in dental implant surgery:a systematic review and meta-analysis of randomized controlled trials

To assess the effectiveness of preemptive analgesia in dental implant surgery in randomized controlled trials (RCTs). The present study was conducted in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and registered in PROSPERO database CRD42020168757. A search without restrictions regarding language or date of publication was conducted in six databases and gray literature. A random effect meta-analysis compared the efficacy of preemptive analgesia compared to placebo through pooled OR and 95%CI. The interpretation of results followed the certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach together with the magnitude of the effect according to GRADE guidelines. Four studies were included in the review and three were incorporated into the meta-analysis. All studies demonstrated that preemptive analgesia contributed to a significant improvement in the postoperative pain control. However, the overall pooled standard mean difference (SMD) showed that preemptive analgesia had small effects compared to placebo in reducing pain (SMD: -0.45; IC: -0.83; -0.08) with low certainty of the evidence. Our meta-analysis showed that the magnitude of the effect was bigger six to eight hours after the surgery (large effect), compared to the time of one to two hours after the surgery (small effect). Preemptive analgesia may have a positive effect in reducing pain compared to not using preemptive medication, but the evidence is very uncertain

Improvement in symptoms and health-related quality of life in acromegaly patients: a systematic review and meta-analysis

Background: Whereas biochemical response is often used as a primary study outcome, improvement in symptoms and health-related quality of life (HRQoL) is the relevant goal for patients to consider treatment successful. We performed a systematic review and meta-analysis to assess the effect of treatment on symptoms and HRQoL in acromegaly.Methods: Seven electronic databases were searched for longitudinal studies assessing patient-reported symptoms or HRQoL in acromegaly. Meta-analyses were performed to assess differences during treatment for the Acromegaly Quality of Life Questionnaire (AcroQoL) and Patient-Assessed Acromegaly Symptom Questionnaire (PASQ), and standardized mean difference (SMD) for individual symptoms (interpretation: 0.2 small, 0.5 moderate, and 0.8 large effect). Treatment-naive and previously treated patients were assessed separately.Results: Forty-six studies with 3301 patients were included; 24 contributed to quantitative analyses. Thirty-six studies used medication as main treatment, 1 transsphenoidal adenomectomy, and 9 various treatments. Symptoms and HRQoL both improved: AcroQoL increased 2.9 points (95% CI, 0.5 to 5.3 points), PASQ decreased -2.3 points (95% CI, -1.3 to -3.3 points), and individual symptom scores decreased for paresthesia -0.9 (95% CI, -0.6 to -1.2), hyperhidrosis -0.4 (95% CI, -0.1 to -0.6), fatigue -0.3 (95% CI, -0.1 to -0.6), arthralgia -0.3 (95% CI, -0.1 to -0.5), headache -0.3 (95% CI, 0.0 to -0.6), and soft-tissue swelling -0.2 (95% CI, 0.0 to -0.4).Conclusion: Symptoms and HRQoL improved during acromegaly treatment. Consensus is needed on which symptoms should be included in a potential core outcome set, taking into account symptom frequency, severity, and sensitivity to change, which can be used in clinical practice and as outcome in trials.Clinical epidemiolog

Spectral method for the time-dependent Gross-Pitaevskii equation with a harmonic trap

We study the numerical resolution of the time-dependent Gross-Pitaevskii equation, a non-linear Schroedinger equation used to simulate the dynamics of Bose-Einstein condensates. Considering condensates trapped in harmonic potentials, we present an efficient algorithm by making use of a spectral Galerkin method, using a basis set of harmonic oscillator functions, and the Gauss-Hermite quadrature. We apply this algorithm to the simulation of condensate breathing and scissors modes.Comment: 23 pages, 5 figure

Efeitos de giberelinas no desenvolvimento do algodoeiro (Gossypium hirsutum L. cv.'IAC-RM3')

Seedlings of cotton were treated 19 days after the sowing with gibberellins at concentrations of 2, 20 and 200 ppm and the check to verify The effect of the compound on the growth of the plant. The experiment was done under greenhouse conditions in 1974. The main proposal of this work is to study the variation of plant height, net assimilation rate, relative growth rate and the leaf area ratio with application of gibberellins. The growth regulator at concentrations of 2, 20 and 200 ppm increased plant height, respectively in 27, 48 and 65% when compared to the control. Application of gibberellins at concentrations of 2 and 20 ppm promotes increase in the net assimilation rate and in the leaf area ratio of cotton. The relative growth rate was superior in the plots that received gibberelins at concentrations of 2, 20 and 200 ppm. It was verified that gibberellins at 200 ppm has a tendency to promote reduction in the net assimilation rate and slight variation in the leaf area ratio in relation to check.Verificou-se o efeito de giberelinas, quando aplicada sob a forma de pulverização das plântulas, no desenvolvimento do algodoeiro cultivar 'IAC-RM3' em condições de casa-de-vegetação. Estudaram-se as concentrações de 0, 2, 20 e 200 ppm do regulador de crescimento; sendo que os tratamentos aumentaram a altura das plantas em 27, 48 e 65%, com relação ao controle. Aplicações de giberelinas nas dosagens de 2 e 20 ppm promoveram aumento na TAL e na RAF do algodoeiro. A TCR foi superior nas plantas tratadas com giberelinas. Verificou-se ainda que giberelinas a 200 ppm promove redução na TAL e variação mínima na RAF, com relação ao controle
