Objective: evaluate the effects of micro focused ultrasound on facial rejuvenation. Methodology: This is an experimental study. The sample consisted of 30 volunteers, who were evaluated before treatment, 45 and 90 days after its beginning. A single application of the MFU was performed across the facial region. The parameters used were: 10 MHz cartridge with depth of 1.5 mm, 7 MHz with depth of 3 mm, and 4 MHz with focal depth of 4.5 mm;doses ranged from 0.1 to 2.0 J, according to the sensitivity of the volunteers treated, and the application time was of approximately 90 minutes. Clinical photographic analysis and facial symmetry analysis using Dolphin Imaging software were performed, and validated questionnaires. Two volunteers were submitted to blepharoplasty surgery, and one to rhytidoplasty surgery 45 days after the application of the MFU. Samples of the treated skin were taken after the surgical procedures and submitted to histological and immunohistochemical analyses. The volunteers answered a questionnaire to assess adverse reactions and satisfaction. Results: We observed a visible clinical improvement on the images by photography, and an improvement of facial symmetry in the measurements of the paralateronasal projection (p = 0.007), left lateral mandibular (p = 0.01), and right lateral mandibular (p = 0.008). The histological analysis showed an increase in the amount of fibroblasts (p = 0.02), blood vessels (p = 0.0062) and inflammatory cells (p = 0.0036), in addition to the production of type 1 collagen. In the immunohistochemical analysis, we observed the presence of the macrophage marker IHQ: CD68, indicating phagocytosis of adipose tissue and the presence of fibrosis. In the analysis of adverse reactions, only transient hyperemia was observed with the presence of pain during application. Additionally, the volunteers expressed high level of satisfaction (93%) with the treatment Conclusion: The MFU promoted the production of collagen, reorganization of the dermis and, clinically, a reduction of sagging and wrinkles, with increased facial symmetry.展开更多

Tecar therapy has been used in clinical practice for the treatment of fat located in the abdominal region. Objective: The objective is to analyse the effect of Tecar therapy on abdominal adiposity. Methodology: This is a clinical trial in which the participants were 32 female volunteers who have flaccidity and fat located in the abdominal region. The volunteers were divided into three groups, which respectively received applications of the capacitive mode, the resistive mode, and combined therapy of the two modalities. We have performed ten applications and analysed the anthropometric measures, the ultrasonography of the adipose layer, and the level of satisfaction. Results: All groups presented a reduction in perimetry compared to the baseline (p = 0.001). The ultrasonography showed a significant reduction in the combined therapy group compared to the baseline (p = 0.04 and p = 0.03). The level of satisfaction was good in all groups, with few adverse responses. In the bodyweight and percentage of fat analyses, we observed an increase in measurements, probably due to the restriction measures related to the new coronavirus pandemic in 2020. Conclusion: In this present study, we have concluded that Tecar therapy resulted in a reduction of the fat located in the abdominal region.展开更多

ATPS experiments were carried out changing the molar average mass of PEG(1500–6000 Da), p H(4.0–7.0), percentage of PEG(10.0–20.0 w/w), percentage of MgSO_4(8.0–16.0 w/w), percentage of the cell homogenate(10.0–20.0 w/w) and the percentage of MnSO_4(0–5.0 w/w) added as cosolute. The network evaluation was carried out comparing the partition coefficients obtained from the hybrid GMDH neural network with the experimental data using different statistical metrics. The hybrid GMDH neural network model showed better fitting(AARD = 32.752%) as well as good generalization capacity of the partition coefficients of the ATPS than the original GMDH network approach and a BPANN model. Therefore hybrid GMDH neural network model appears as a powerful tool for predicting partition coefficients during downstream processing of biomolecules.展开更多

The experiment was conducted in a cotton experimental field of EMBRAPA located in Ceará State, Brazil. Seven TM Landsat-5 images acquired in 2005 and 2008 were used to perform SEBAL and SSEB algorithms. The comparison between the estimated values by remoting sensing algorithms and the measured values in situ showed an acceptable accuracy. Besides, SSEB algorithm showed to be an important tool for ET analysis in the semi-arid regions, due to the fact that it does not need the meteorological data to solve the energy balance, but only the average temperature of the “hot” and “cold” pixels. Additionally, SSEB presents simpler processing than SEBAL algorithm that needs to solve an iterative process to obtain the sensible heat flux values.展开更多

For this, we used a dataset covering the 1981 to 2010 period, composed by: monthly data of accumulated precipitation of the Global Precipitation Climatology Project (GPCP);surface fluxes obtained from reanalysis of the National Center for Environmental Prediction (NCEP);vertically integrated moisture flux divergence of the global model of European Centre for Medium Range Forecasting (ECMWF) reanalysis;SST data from the NCEP. Seven GRAD_S (southward SST gradient in the intertropical Atlantic) and five GRAD_N (northward SST gradient in the intertropical Atlantic) were selected. When the South Atlantic Ocean is warmer, the oceanic and atmospheric conditions are favorable to higher monthly precipitation near to the ENEB. We also observed a pronounced moisture convergence over parts of the ENEB during both, GRAD_S and GRAD_N episodes. The weather phenomena that operates remotely amplifying or inhibiting the rain also helps the rainy season;however, it appears that the contribution was greater than the spatial distribution of rainfall intensity.展开更多

The period considered extend between 2000 and 2011, in which it was possible to pair meteorological data and the reporting of dengue patients worsening. These data should also be considered in the numerical model, by assimilation, to obtain simulations of Dengue epidemics. The model contains compartments for the human population, for the vector Aedes aegypti and four virus serotypes. The results provide consistent evidence that worsening infection and disease outbreaks are due to the occurrence of environmental precursors, as the dynamics of the accumulation of water in the breeding and energy availability in the form of metabolic activation enthalpy during pre-epidemic periods.展开更多

An insulating material may suffer from the most different efforts, but the major applications suggest mechanical bending and compression tests because the insulation can be applied on roofs of homes, liners similar to, in the form of plates. Thus, the product is continually flexed. When the material is used on a floor, it suffers constant compressions over its use. For tests performed in this study, we used the ASTM D695-96 for compression, an example of literature. Using such a standard test, specimens were produced for compression test, with specimens made of cylindrical shapes, respecting the condition that the height of the specimen corresponds to twice the diameter of the base. Polyurethane castor without charge vermiculite and mass loads of 10%, 15% and 20% matrix： four specimens for each type of material were produced. The composites were tested in a universal testing machine at a speed of 2 mm/s. The results are average values of four test samples, and initially show the behavior of castor oil polyurethane during the compression test, which is detailed in the stress versus strain curve. The achieved results are promising, and detailed in this paper.展开更多

Cirrhosis changes the prognosis of the subject with hepatitis C and requires a different clinical management. This study aimed to identify clinical and laboratory variables associated with the diagnosis of cirrhosis in the ultrasonography of patients infected with hepatitis C. In a case-control study, we evaluated 70 cirrhotic patients with chronic hepatitis C compared to a control group of 70 non-cirrhotic people with positive HCV. The results showed, through logistic regression analysis, that the variables blood donor and professional athlete, adjusted for alcohol consumption, showed OR 0.24 and 0.18, with p values of 0.044 and 0.035, respectively. We conclude that the diagnosis of cirrhosis in patients with chronic hepatitis C remains challenging, but the patients with the condition of blood donor or professional athlete prove to be less likely to cirrhosis in ultrasonography in the initial consultation.展开更多

The objective function must be chosen so that its value represents the operation state of the system. As the problem possesses combinatorial nature, its complexity will increase exponentially with the number of possibilities. Systems with large numbers of nodes and / or with the possibility of installing more than one bank require a large number of calculations to find the solution. An additional issue is the fact that the problem does not have a continuous nature, presenting discontinuity points in the objective function, limiting the application of optimization methods based on gradients. Based on the nature of the problem two optimization methods were used to solve the problem: Genetic Algorithm (GA) and modified Tabu Search (TS). The GA function will scour the search space and find regions with local minima that are candidates to be the solution. On the other hand the TS provides local search in the regions defined by GA so that the overall optimum is achieved.展开更多

The results showed, through logistic regression analysis, that the variables blood donor and professional athlete, adjusted for alcohol consumption, showed OR 0.24 and 0.18, with p values of 0.044 and 0.035, respectively. We conclude that the diagnosis of cirrhosis in patients with chronic hepatitis C remains challenging, but the patients with the condition of blood donor or professional athlete prove to be less likely to cirrhosis in ultrasonography in the initial consultation.
文摘This work aims to verify how the Web portals of Universities Hospital located in the northeast of Brazil are contributing to the expansion of knowledge of its users from the analysis of interactive features associated with the three mechanisms of knowledge management： knowledge access （KA）, knowledge creation （KC）, and knowledge transfer （KT）. The study is exploratory, descriptive, and qualitative type, such as a survey, developed through an adaptation of a relevant research, which involves the standardization of data collection instruments （questionnaires and interviews） applied directly to persons of a specific population, to assess knowledge management tools present in the University Hospital portals in the northeast region of Brazil. The results indicated that the resources from knowledge access were more prevalent than the others, ratifying the results found in research developed in Asian and North American Hospital portals.
文摘The optimal allocation of regulators banks in distribution systems is a merely combinatorial problem in which the best points of installation correspond to the best benefit, considering the admitted objective function, without violating and operating limits. The objective function must be chosen so that its value represents the operation state of the system. As the problem possesses combinatorial nature, its complexity will increase exponentially with the number of possibilities. Systems with large numbers of nodes and / or with the possibility of installing more than one bank require a large number of calculations to find the solution. An additional issue is the fact that the problem does not have a continuous nature, presenting discontinuity points in the objective function, limiting the application of optimization methods based on gradients. Based on the nature of the problem two optimization methods were used to solve the problem: Genetic Algorithm (GA) and modified Tabu Search (TS). The GA function will scour the search space and find regions with local minima that are candidates to be the solution. On the other hand the TS provides local search in the regions defined by GA so that the overall optimum is achieved.
文摘<strong>Introduction:</strong> Cryofrequency is a novel therapy which was developed with the combination of cold (cryotherapy) and heat (radiofrequency) application, causing a thermal shock effect on skin tissue. The thermal shock is believed to alter local metabolism. <strong>Objective:</strong> To investigate the effect of cryofrequency on the skin tissue of a mini pig in an <em>in vitro </em>and <em>in vivo</em> experimental model. <strong>Methodology:</strong> A small swine of the <em>S. domesticus </em>species, a male mini-pig (30 kg weight) was elected for the <em>in vivo</em> procedure subject. The <em>in vitro</em> step was performed on the extracted abdominal part of another subject of the same species and breed. Then, after the application of cryofrequency in the monopolar and bipolar form <em>in vivo</em>, a histological analysis was performed. <strong>Results: </strong>A higher temperature variation was observed comparing the pilot study <em>in vitro </em>with respect to the experimental one <em>in vivo</em>. Microscopically, an increase of collagen fibers and blood supply and decreased adipose tissue was observed after cryofrequency application. <strong>Conclusion:</strong> With the bipolar cryofrequency, no reduction of adipose tissue was observed, but regarding the connective tissue, extensive areas of collagen deposition were observed, as well as a great amount of new-formed collagen fibers.
文摘Cryofrequence is the combination of cryotherapy with radiofrequency, which promotes a “thermal shock” to the tissue, working simultaneously to skin flaccidity and localized adiposity. The efficacy of dermatological and hypodermic cryofrequency treatment was evaluated. This study reports the case of a 45-year-old woman with complaints of flaccidity and fat located in the infra-umbilical region in the preoperative period of abdominoplasty. The evaluation was performed before and after treatment through evaluation protocols, ultrasound examinations and histological findings through optic microscopy, microfocal and immunohistochemical analysis. The treatment was performed in 4 sessions, with a weekly application, using the BHS 156 FULL®—BODY HEALTH BRASIL®apparatus, the parameters were temperature of -10°C, power in 70%, duration of 8 minutes. After the surgical procedure, parts of treated and untreated abdominal tissues were removed for evaluation. In the tests performed, significant destruction of adipocytes was detected, with consequent reduction of fat and greater expression of caspase-3 in the treated tissue, being constated the macrophage increase by CD68 expression. There was improvement in flaccidity, evidenced by the significant increase in the number of fibroblasts and inflammatory cells positive for Ki67, bringing more quantity and better quality to the collagen.
文摘The aiming of this worksheet is to evaluate and to compare the quantity of prenatal appointment indicators;childbirth by kind of delivery;maternal mortality coefficient and maternal deaths number. It is about an ecological, descriptive and analytical study, made through the appreciation of secondary data related to the maternal mortality in Rio Grande do Norte, from 2000 to 2014. To that, it was used information from SISPACTO to compare real data to the estimated goals. The results show that there was an increase on the number of women who performed seven or more prenatal queries, in turn, there was an increase of alive newborns through cesarean, moreover, it is observed an oscillation on the maternal deaths number by residence during the studied period, achieving superior values to the agreed goals during the last two analyzed years. It is concluded that the maternal health, in Rio Grande do Norte, negative indicators are being presented concerning the maternal mortality, in spite of presenting an improvement on the prenatal access.

文摘Perinatal asphyxia is defined as harm to the fetus or the newborn caused by hypoxia and/or ischemia of various organs with intensity to produce biochemical and/or functional changes. Understanding the risk factors for this clinical condition allows the identification of vulnerable groups, enabling an improvement in care planning in the perinatal period in neonatal intensive care units. In this sense, this research aimed to identify risk factors for perinatal asphyxia present in newborns term that showed record for this clinical condition. This was a cross-sectional, retrospective documentary, quantitative and descriptive, conducted from data from medical records of 55 infants admitted to a neonatal intensive care unit. As for maternal characteristics (78.0%) had between 16 and 35 years, only one child (53.0%) and (76.0%) had no prior history of miscarriage. As for pre-existing diseases or pregnancy (38.0%) developed by Hypertensive Pregnancy Specific disease (02.0%) were suffering from Hypertension and (02.0%) of Diabetes Mellitus. As for newborns, most infants had birth weight (43.6%) and correlation with gestational age (78.2%) compatible for good conditions of birth. Only (20.0%) of the infants had a difficult labor. It stood out although there was a slight predominance of severe asphyxia (50.9%) in the first minute and (45.5%) of the infants had record release intrauterine meconium. It was concluded that most mothers and newborns did not have risk factors for perinatal asphyxia, thus, this fact could be attributed to the structural conditions of service, especially in the care during labor, delivery and immediate assistance newborn.
文摘Introduction: In the 1990s, the development of highly active combination antiretroviral therapy in the treatment of AIDS was highlighted. The great benefit generated by the use of this treatment was the prolongation of survival of the people who got this disease, since it is no longer considered fatal, becoming a chronic condition. Objective: To identify the prevalence of the nursing diagnosis Lack of Adherence, its defining characteristics and related factors in people living with AIDS, to investigate the association between them and the prevalence rates. Methods: Cross-sectional study with 113 patients in a hospital in northeastern Brazil. For data analysis, the test of Pearson chi-square and Fisher’s exact test were used, and also calculated the prevalence rates. Results: Lack of Adherence diagnosis was present in 69% of the sample investigated. The defining characteristics and related factors that are statistically associated with that diagnosis were: lack of adherence behavior, missing scheduled appointments, complications related to development, insufficient skills to implement the system and complex treatment system. The first two characteristics had the highest chances for the development of this diagnosis. Conclusion: The study showed that the diagnostic studied was prevalent in these patients and 3 characteristics and 2 factors showed significant association.
