title: Acute clinical manifestations in toxic smoke inhalation victims: systematic review of observational studies

description: Abstract Introduction: Lung injuries from toxic smoke inhalation are the main causes of death in fire victims; however, information regarding the acute effects on the respiratory system after smoke inhalation and its constituents in closed environments are still scarce in literature. Objective: To investigate the acute clinical manifestations observed in victims of smoke inhalation during enclosed-space fires by means of systematic review. Methods: A systematic search was conducted in the following databases: MEDLINE (via PubMed), Lilacs, Scopus and Web of Science. There were no appliedrestrictions in terms of thepublication date. In addition, a manual search was performed on the references of published studies. Observational studies assessing the prevalence of acute clinical manifestations in victims of toxic smoke inhalation in closed environments were included. Results: Of the 4,603 articles identified, eight were included, comprising a total of 233 patients. The signs and symptoms were identified and ranked according to frequency. Dyspnea (58.80%, six studies), carbonaceous sputum (54.51%, four studies), hoarseness (39.91%, three studies), wheezing (34.33%, five studies) and sore throat (33.90%, two studies) were the most frequent acute clinical manifestations of smoke inhalation. Besides these, chest pain and pulmonary edema were observed, respectively in 13.30%, 5.15% of the studies. Conclusion: The results suggest that dyspnea, carbonaceous sputum, hoarseness, wheezing and sore throat were the most frequent acute clinical manifestations in victims of smoke inhalation. Further studies of a higher level of evidence and greater methodological rigor are required.

title: Photobiomodulation and physical exercise on strength, balance and functionality of elderly women

description: Abstract Introduction: Aging is associated with structural changes in muscle tissue, which leads to the loss of functional independence. The preservation of the muscle strength through strength training, and recently, low-level laser therapy (LLLT), has high clinical significance. Objective: to investigate the effects of photobiomodulation (PBM - 808 nm, 100 mW, 35.7 W/cm2 and 7 J) associated with a strength training program on quadriceps muscle strength, balance and functional capacity in elderly women. Methods: Thirty-five healthy women between 60 to 70 years old were divided into two groups: Placebo Group (n = 13) and Active Group (n = 14). The exercise protocol consisted of knee flexion-extension exercise followed by application of PBM placebo or active, twice a week for 8 consecutive weeks. Results: showed a significant increase in 6MWT (p = 0.001), SPPB (p = 0.006) and 1-MR (p = 0.001) in both groups. The strength training program associated with PBM active improved a significant increase, relative to baseline, to the right medial/lateral stability index (p = 0.007) and decrease in the Fall Risk Test (p = 0.005). Conclusion: the strength training produced a significant increase of muscle strength and functionality and when combined with the PMB it was significant in the improvement of postural stability and decrease of fall risk.

title: Setting up finite transforms using Sturm--Liouville Theory

description: Abstract Initial and boundary value problems are very common in physics, mathematics, and engineering. They can model many types of problems related to heat diffusion and membrane vibration, for example. When the analytical solution of these problems is needed one may find extra difficulties when the boundary conditions that describe the phenomena are nonhomogeneous. In this way, in this work is presented a technique for solving initial and boundary problems by means of integral transformations. The differential of the presentation is in the construction of the integral transform appropriate to the solution of the problem. These transformations are known as finite transforms and in this case they are related to a Sturm--Liouville problem associated with the differential operator connected to the differential equation. As an example, we solve two problems of heat diffusion in different spatial coordinates systems. The presentation of the work follows in pedagogically and self-contained fashion. Therefore, we expect the reader to understand the technique and can use it in solving other problems involving partial differential equations.

title: Pseudocapacitance Properties of Co3O4 Nanoparticles Synthesized Using a Modified Sol-Gel Method

description: This work reports the synthesization of nanoparticles cobalt oxide (Co3O4) with no secondary phase by a modified sol-gel method and its structural morphological and electrochemical characterizations. FTIR, XRD and Raman analysis showed the formation of spinel cobalt oxide with no secondary phase. TEM images revealed that an undefined morphology with average crystallite size estimated by Scherrer's equation was found to be 30 nm. Experiments of cyclic voltametric, galvanostatic charge-discharge and impedance spectroscopy were evaluated at 1 mol L-1 KOH and revealed an intrinsic pseudocapacitance. The studies of complex capacitance and complex power revealed the resistive and capacitive characteristics with a specific capacitance of 120 F g-1.

title: Influence of Pellet Compaction Pressure on the Physical Properties of La0.7Ba0.3MnO3 Manganite

description: Perovskite manganite La0.7Ba0.3MnO3, synthesized by ionic coordination reaction method (ICR) was compacted into pellets under different compaction pressures (Pc) and sintered at a temperature of 1150°C for 10h under a flow of O2. X-ray diffraction (XRD) data reveal that the samples can present simultaneously two phases - a rhombohedral structure with space group R3c and an orthorhombic structure with space group Pnma. Scanning electron microscopy (SEM) images show that, for this sintering temperature, the particle size and shape can be modified depending on the compaction pressure (Pc). Magnetization measurements show that the saturation magnetization and Curie temperature increase with Pc. The enhancement of the ferromagnetic properties of perovskite manganites La0.7Ba0.3MnO3 as a function of the compaction pressure is explained by an increase in the rhombohedral/orthorhombic structure ratio caused by this effect.

title: Evaluation of the effectiveness of preoperative outpatient pulmonary preparation in patients undergoing esophageal surgery

description: Abstract Introduction: Preoperative inspiratory muscle training (IMT) can minimize the occurrence of complications after esophagectomy. Objective: To evaluate the effects of preoperative IMT in patients undergoing esophageal surgery by determining respiratory muscle strength (PImax and PEmax), pulmonary function (FEV1, FVC, FEV1/FVC) and functional capacity by the 6-minute walk test (6MWT). Methods: Twenty-two patients were randomized into two groups: a control group (CG; n = 10) and an intervention group (IG; n = 12). Only IG performed IMT for a minimum period of 2 weeks. The assessments were conducted pre- and post-surgery. Results: An increase of PImax was observed in IG, but not in CG, in the second preoperative assessment (p = 0.014). Assessment on postoperative day 1 showed a reduction in maximal respiratory pressures in the two groups, but the reduction was more marked in IG (p &lt; 0.05). Partial recovery of the variables evaluated was observed at discharge in the two groups. These variables had fully returned to initial values on postoperative day 30. The distance walked in the 6MWT was greater in IG, but the difference was not significant (p = 0.166). There was no difference in the frequency of pulmonary complications between groups. Conclusion: Preoperative IMT performed in our study improved inspiratory muscle strength but did not influence the postoperative pulmonary function or functional capacity of patients undergoing esophagectomy.

title: Sarcopenia: prevalence and associated factors among elderly from a Brazilian capital

description: Abstract Introduction: Sarcopenia has been currently considered a public health problem, affecting a large portion of the elderly and making them more susceptible to the risk of falls. Objective: To estimate the prevalence and factors associated with sarcopenia in the elderly from a Brazilian capital. Methods: This is an epidemiological study with cross-sectional design involving data of 439 elderly people from Florianópolis city, Santa Catarina state. The factors potentially associated with sarcopenia (sex, age, weight status) were tested using binary logistic regression, estimating the Odds Ratio and the respective confidence intervals. Results: The prevalence of sarcopenia was 33.3% (95% CI: 28.9, 36.9). Older women (75 years or more) showed less muscle mass in relation to other age groups (p &lt; 0.05). Elderly men, individuals that are 75 years or more, and those with low weight were the subgroups at higher risk for sarcopenia. Obese individuals were less likely to have the outcome. Conclusion: More than one-third of elderly people were diagnosed with sarcopenia. Men, individuals who are older, and those with low weight had a higher risk of having sarcopenia.
