Aquatic myofascial release applied after high intensity exercise increases flexibility and decreases pain.

OBJECTIVES: To investigate aquatic myofascial release (AMR) effects on flexibility and delayed onset muscle soreness, after high intensity exercises. STUDY DESIGN: 15 participants, control (CON) and intervention (INT), 3 moments, pre (Pre), after (Post) and 50 min after (Post 50/Post AMR). 6 exercises, 5 sets, 15 reps at 85% of 1 maximum repetition, followed, or not, by 50 min of AMR. VARIABLES: Heart rate, lactate, rate of perceived exertion, pain and flexibility. RESULTS: Pain perception decreased in all moments (CON4.47 ± 2.36; INT1.13 ± 1.46, p = 0.0002). Flexibility only increased for the fingertip to floor test in both phases in the Post50/Post AMR compared to Post (CON14.33 ± 9.19Pre, 15.07 ± 9.37Post (p = 0.7) and 12.8 ± 4.69Post50 (p = 0.4); INT14.53 ± 9.06Pre, 13.87 ± 9.88Post (p = 0.2) and 11.03 ± 8.96Post AMR (p = 0.001)). The Well's bench improved only for the Post AMR compared to Pre in the INT phase (INT24.79 ± 9.91Pre; 27.67 ± 9.46Post AMR p = 0.0000023). CONCLUSION: We concluded that AMR is effective to reduce pain perception and to improve flexibility of the studied population submitted to a high intense exercise session.

Human biological and nonbiological point-light movements: Creation and validation of the dataset.

Human action perception is so powerful that people can identify movement efficiently in the absence of pictorial information, such as in point-light displays. Interest is growing in this type of stimulus for research in neuroscience. This interest stems from the advantage of separating the component of pure human action kinematics from other pictorial information, such as facial expression and muscle contraction. Although several groups have previously developed datasets of human point-light actions, due to the lack of datasets composed of daily actions with short durations, we developed 20 biological and 40 control (scrambled) point-light movements by using the technique of recording people wearing reflector patches. The videos are about 1 s long. Subsequently, we performed a judgment task in which 100 participants (50 male and 50 female) evaluated each video according to three categories: human action resemblance, performed action, and gender of actor. We present the mean scores of each evaluation for each video, and further propose a selection of the most suitable videos to be used as human point-light action displays and scrambled point-light displays for control. Finally, we discuss our findings on the gender attributions of the point-light displays.

Compreensão dos acadêmicos de enfermagem sobre trabalho colaborativo / La comprensión de los estudiantes de enfermería en el trabajo colaborativo / Understanding of nursing students about collaborative work

To identify the understanding of nursing students in relation to collaborative work. Methods: a descriptive exploratory study with a qualitative approach, semi-structured interview, held in a Faculty of Curitiba-PR. It included 30 nursing students. Results: through Bardin Content analysis we identified the following categories: collaborative work seen as teamwork; collaborative work between the nursing staff: areas of use; decision-making: understanding the academic students; shared decision: understanding the academic students. Conclusion: collaboration opens an increasing space and positive valuation for individuals, as well as to get different results when it’s compared with those obtained by individual effort, the relationship between the members of the group operates on a constructive dependence in terms of valuing the other...

Data reproducibility of pace strategy in a laboratory test run.

This data paper contains data related to a reproducibility test for running pacing strategy in an intermittent running test until exhaustion. Ten participants underwent a crossover study (test and retest) with an intermittent running test. The test was composed of three-minute sets (at 1 km/h above Onset Blood Lactate Accumulation) until volitional exhaustion. To assess pace strategy change, in the first test participants chose the rest time interval (RTI) between sets (ranging from 30 to 60 s) and in the second test the maximum RTI values were either the RTI chosen in the first test (maximum RTI value), or less if desired. To verify the reproducibility of the test, rating perceived exertion (RPE), heart rate (HR) and blood plasma lactate concentration ([La]p) were collected at rest, immediately after each set and at the end of the tests. As results, RTI, RPE, HR, [La]p and time to exhaustion were not statistically different (p>0.05) between test and retest, as well as they demonstrated good intraclass correlation.

Aspectos epidemiológicos de pacientes com lesões ungueais e cutâneas causadas por Scytalidium spp / Epidemiological aspects of patients with ungual and cutaneous lesions caused by Scytalidium spp

FUNDAMENTO: As dermatomicoses causadas por fungos filamentosos não dermatófitos são infecções raras, exceto as onicomicoses, cuja prevalência vem crescendo nos últimos anos. Dentre esses agentes etiológicos destacam-se o Scytalidium dimidiatum e o S. hyalinum, fungos emergentes responsáveis por micoses em unhas e pele. OBJETIVO: Investigar as características epidemiológicas das onicomicoses e micoses de outras localizações causadas pelos fungos do gênero Scytalidium, utilizando-se como parâmetros sexo, idade e localizações das lesões. MÉTODOS: Avaliaram-se 81 amostras com cultura positiva para o gênero em estudo, oriundas de 74 pacientes encaminhados ao Laboratório de Investigação em Dermatologia (ID) situado na cidade do Rio de Janeiro (RJ), no período de 1997 a 2006. As amostras foram submetidas a confirmação diagnóstica por exame direto e cultura. RESULTADOS: A prevalência de onicomicoses por Scytalidium spp. foi de 0,87 por cento, entre as idades de 41 e 60 anos (48,64 por cento). Em relação à localização das lesões, os pés foram mais acometidos (91,36 por cento), com predomínio do hálux esquerdo. No exame direto, as estruturas mais encontradas foram hifas hialinas; na cultura, a espécie S. dimidiatum foi a mais frequente. CONCLUSÃO: As onicomicoses por Scytalidium spp. são raras e o S. dimidiatum foi a espécie mais isolada neste laboratório no período em estudo.

BACKGROUND: Dermatomycoses caused by non-dermatophyte filamentous fungi are rare infections, except for onychomycosis, whose prevalence has increased over the past few years. Among these etiologic agents, we highlight Scytalidium dimidiatum and S. hyalinum, emergent fungi that cause mycoses that affect the nails and skin. OBJECTIVE: To investigate the characteristics of onychomycosis and other mycoses caused by the fungi Scytalidium spp, using sex, age and site of infection as parameters. METHODS: Eighty-one samples were evaluated showing positive culture for Scytalidium spp, obtained from 74 patients referred to the Laboratory of Investigation in Dermatology (ID) located in the city of Rio de Janeiro, RJ, between 1997 and 2006. The samples were submitted to diagnostic confirmation through direct exam and culture. RESULTS: The prevalence of onychomycosis caused by Scytalidium spp. was of 0,87 percent. The most prevalent age was between 41-60 years (48.64 percent). Regarding the site of infection, the feet (91.36 percent) were most affected, with predominance of the left hallux. Hyaline hyphae were the most common structures in direct examination and the species S. dimidiatum was the most frequent in culture. CONCLUSION: Onychomycosis caused by Scytalidium spp. is rare and S. dimidiatum was the most isolated species in this laboratory during the period of the study.
