RESUMO

BACKGROUND: The COVID-19 pandemic and the need for social distancing created challenges for accessing and providing health services. Telemedicine enables prompt evaluation of patients with traumatic brachial plexus injury, even at a distance, without prejudice to the prognosis. The present study aimed to verify the validity of range of motion, muscle strength, sensitivity, and Tinel sign tele-assessment in adults with traumatic brachial plexus injury (TBPI). METHODS: A cross-sectional study of twenty-one men and women with TBPI admitted for treatment at a Rehabilitation Hospital Network was conducted. The participants were assessed for range of motion, muscle strength, sensitivity, and Tinel sign at two moments: in-person assessment (IPA) and tele-assessment (TA). RESULTS: The TA muscle strength tests presented significant and excellent correlations with the IPA (the intra-rater intraclass correlation coefficient, ICC ranged between 0.79 and 1.00 depending on the muscle tested). The agreement between the TA and IPA range of motion tests ranged from substantial to moderate (weighted kappa coefficient of 0.47-0.76 (p < 0.05) depending on the joint), and the kappa coefficient did not indicate a statistically significant agreement in the range of motion tests of supination, wrist flexors, shoulder flexors, and shoulder external rotators. The agreement between the IPA andTA sensitivity tests of all innervations ranged from substantial to almost perfect (weighted kappa coefficient 0.61-0.83, p < 0.05) except for the C5 innervation, where the kappa coefficient did not indicate a statistically significant agreement. The IPA versus TA Tinel sign test showed a moderate agreement (weighted kappa coefficient of 0.57, p < 0.05). CONCLUSIONS: The present study demonstrated that muscle strength tele-assessment is valid in adults with TBPI and presented a strong agreement for many components of TA range of motion, sensitivity, and Tinel sign tests.

RESUMO

BACKGROUND: The expansion of the rib cage and abdomen occurs in a synchronic way during a coordinated contraction of the diaphragm and the abdominal and intercostal muscles under normal conditions and healthy. The presence of restrictive respiratory disease may lead to uncoordinated action of the respiratory muscles which affects breathing pattern and chest wall volumes. The aim of this study was to evaluate chest wall volumes, chest wall asynchrony and inspiratory paradoxical movement of breathing, as well as the influence of the time of disease diagnosis in subjects with Parkinson's disease and post-Stroke in comparison to healthy individuals. METHODS: Total and compartmental chest wall volumes, chest wall asynchrony and paradoxical movement were measured at rest in a seated position by Optoelectronic Plethysmography in 76 individuals (29 healthy individuals, 20 post-Stroke and 27 Parkinson's disease subjects). Post-stroke and Parkinson's disease subjects were also grouped according to the length of diagnosis. RESULTS: In both groups with restrictive respiratory disease we observed that pulmonary rib cage compartment (VRCp) volume is reduced when compared to healthy subjects (p <0.05). This same pattern was observed when analyzing post-stroke subjects with more than three years of diagnosis and Parkinson's subjects with less than three years of diagnosis (p<0.05). Furthermore, post-stroke subjects with inspiratory paradoxical movement showed decreased total and compartmental chest wall volumes (p<0.05), while individuals with Parkinson's disease with inspiratory paradoxical movement only presented a decrease in pulmonary rib cage compartment volume (p<0.05). CONCLUSION: Our study presents new findings for better understanding of chest wall volumes and chest wall asynchrony in post-stroke and Parkinson's disease individuals. Half of the subjects with post-Stroke and Parkinson's disease presented inspiratory paradox movement, but changes in breathing pattern was especially observed in post-stroke subjects with more than three years of diagnosis.

RESUMO

BACKGROUND: Chest physiotherapy can be an alternative to increase lung volumes through pulmonary expansion therapies, but there is still inconsistency in the literature in order to determine which device can promote a greater volume increase at the expense of a better ventilatory pattern. Therefore, the aim of this study was to evaluate and compare the chest wall kinematics of healthy subjects submitted to the use of three different devices for pulmonary reexpansion. METHODS: Chest wall compartmental and operational volumes, breathing pattern and thoracoabdominal asynchrony were evaluated in 12 healthy individuals through optoelectronic plethysmography during quiet breathing, pulmonary reexpansion and recovery. Three different devices (volume-oriented incentive spirometer-IS-v; positive expiratory pressure-PEP; and incentive spirometer volume and pressure oriented-IS-vp) were administered in a random order with at least 48h between the devices. RESULTS: A greater volume variation in the chest wall and its compartments was observed when the IS-vp was used in comparison with the other devices (p<0.05). Furthermore, the IS-vp mobilizes a greater amount of volume accompanied by greater synchronism between the compartments when compared to IS-v (p <0.05). CONCLUSION: The IS-vp may be able to increase total and compartmental chest wall volumes, as well as improve synchrony among compartments when compared to IS-v and PEP devices, thus constituting an important tool for treating patients with restrictive ventilatory pattern.

RESUMO

A universidade tem se mostrado como lugar de crescimento intelectual, de construção de perspectivas e de convívio social. Estudos atuais demonstram que habilidades sociais e humor são fundamentais para uma comunicação eficaz, para o crescimento profissional e o bem ‑estar psicológico individual e grupal. O presente estudo teve como objetivo investigar a relação entre habilidades sociais e humor em estudantes universitários. Participaram 167 estudantes que responderam à Escala de Senso de Humor Situacional e ao Inventário de Habilidades Sociais. Os resultados mostraram que o humor está associado às habilidades sociais e que o fator “humor com amigos e colegas” pode ser considerado preditor de alguns fatores das habilidades sociais.

The university has now shown as a place of intellectual growth, building prospects and social life. Current studies show that humor and social skills are the key to an effective communication for professional growth and psychological well‑ being of individual and group. The present study aimed to investigate the relationship between social skills and mood in college students. Participated 167 students, that filled the sense of Humor Scale Situational and the Social Skills Inventory. The results showed that the humor is associated with social skills and that “humor with friends and colleagues” can be considered a predictor of some factors of social skills.

RESUMO

The inoculation of leguminous plants with rhizobia is one of the main methods of biotechnological use of microorganisms in order to obtain biological nitrogen fixation in agriculture. However, in recent years it has been attributed to these microorganisms the ability to produce phytohormones, mainly indole acetic acid (IAA), and to promote the growth in grasses. Thus, the objectives of this study were to quantify the indole acetic acid produced by rhizobia from alfalfa and to evaluate the effect of inoculation of these microorganisms on the germination of rice seed and to perform the genetic characterization of these isolates. Nine rhizobia, from nodules of alfalfa, were evaluated for their ability to produce IAA equivalents and for their influence in inoculating these microorganisms on germination and seedling development of rice. Moreover, these rhizobia producers of IAA were identified by the 16S region of DNAr. The equivalent production of indole acetic acid was observed in all tested isolates, with values ranging from 43.04 to 101.26µg mL-1 in culture medium. Regarding the germination of rice seeds, the inoculation with rhizobia accelerated this germination and its growth. Microorganisms UFRGS Ms58, UFRGS Ms515, UFRGS Ms195, UFRGS Ms205, UFRGS Ms2010 and UFRGS 2012 were identified as belonging to the species of Sinorhizobium meliloti. Microorganisms Ms55 UFRGS, UFRGS Ms75 and UFRG Ms72 were identified as belonging to the species of Rhizobium sp.

Nove rizóbios isolados de nódulos de alfafa foram avaliados quanto a sua capacidade de produção de equivalentes de AIA e a influência da inoculação desses micro-organismos na germinação e desenvolvimento de plântulas de arroz. Os rizóbios produtores de AIA foram identificados pelo sequenciamento da região do gene 16S do DNAr. A produção de equivalentes ao ácido indol-acético foi observada em todos rizóbios, com valores que variaram de 43,04 a 101,26µg mL-1 em meio de cultura. Com relação à germinação das sementes de arroz, a inoculação com rizóbios acelerou o processo e o crescimento de suas plântulas. Os rizóbios UFRGS Ms58, Ms515, Ms195, Ms205, Ms2010 e 2012 foram identificados como pertencentes à espécie Sinorhizobium meliloti e UFRGS Ms55, Ms72 e Ms75 à espécie Rhizobium sp.
