引用

International Journal of Clinical Medicine 2018年第9期9卷 737-749页

作者： Omero Benedicto Poli-Neto Raquel Verceze Bortolieiro Júlio Cesar Rosa-e-Silva Francisco Jose Candido-dos-reis Antonio Alberto Nogueira Department of Gynecology and Obstetrics Ribeirao Preto Medical SchoolUniversity of Sao PauloRibeirao PretoSPBrazil

Objective: To assess the satisfaction and occupational performance of women with chronic pelvic pain and to discuss unassisted intervention strategies by the occupational therapist for the care of these patients. Methods: A case-control study was conducted on 75 women with chronic pelvic pain and 75 apparently healthy women. The study was approved by the Research Ethics Committee of the institution and all subjects gave written informed consent to participate. Pain intensity was determined using a visual analogue scale and each patient was submitted to psycho-metric assessment using the Patient Health Questionnaire, the Self-Reporting Questionnaire of Psychiatric Screening and the Tampa Scale of Kinesiophofobia in their Brazilian version. The main outcomes regarding occupational performance and satisfaction were evaluated using the Canadian Measure of Occupational Performance. Results: The performance and satisfaction scores of women with chronic pelvic pain were significantly lower than those of healthy women. The presence of pain and kinesophobia was directly and independently correlated with low performance and satisfaction scores regardless of ethnicity, marital status, schooling, or psychometric scores. Conclusion: women with chronic pelvic pain present significant impairment of satisfaction and occupational performance. Coping is a potential unassisted intervention strategy to be applied to this population by occupational therapists.

This work intended to characterize the seed morphology, water absorption patterns and to determine the vigor among different colored seeds of the species Centrolobium paraense （Fabaceae）. For this purpose, samaras which were opened were collected from two sites---Agua Boa （AB） and Taiano （TAI） lo^ated in the state of Roraima, and the seeds screened by the coat coloration （light brown/intermediate brown/dark brown） for four conditions （two sites and two years of collection）. Evaluation of water absorption by the seeds at different periods, mass of 1,000 seeds, water content, electrical conductivity （EC）, seedling emergence and emergence velocity （EV） were performed. The water absorption by the seeds of Centrolobium paraense indicates coat permeability to water and distinct absorptions according to coat colorations. The EC test is efficient in determining the physiological quality of seeds of Centrolobium paraense. Seed coat coloration affects the physiological quality of the seeds of Centrolobium paraense. It is possible to distinguish the seeds of AB and TAI into two degrees of physiological quality, the light brown-colored seeds being more vigorous.

Blindness is a serious complication that can occur after facial trauma and may represent the loss of one of the most useful senses in the human relationship with the world—the sight. This study aims to review the pathophysiology of blindness related to facial trauma in order to identify the mechanisms by which it develops and to recognize the signs and symptoms required to establish proper diagnosis and treatment. Blindness following facial trauma may occur due to mechanisms that involve injury to the eyeball, optic nerve and eyelids. The leading causes of blindness resulting from facial trauma, and which may be altered by medical interference, are related to retrobulbar hemorrhage and traumatic optic neuropathy, which require extremely rapid diagnosis and can be accomplished with the resources available in most trauma-based emergency services. The authors conclude that loss of vision tends to be irreversible in direct eyeball and optic nerve lesions, but can be prevented in retrobulbar hemorrhage and traumatic optic neuropathy. Eyeball and, especially, sight accuracy evaluation should be included in the initial care of trauma patients, so that the lesions that might lead to loss of vision are diagnosed and treated early.

作者： Fernanda Raphael Escobar Gimenes Patrícia Costa dos Santos da Silva Andréia Regina Lopes Renata Karina reis Rebecca Shasanmi Emília Campos de Carvalho Department of General and Specialized Nursing University of S&atildeo Paulo at Ribeir&atildeo Preto College of Nursing Ribeir&atildeo Preto Brazil Federal University of Uberlandia Uberlandia Brazil Academy of the Brazilian Air Force Pirassununga Brazil Nursing and Public Health Research Philadelphia PA USA

The objective was to identify the most frequent nursing diagnoses labels in patients with liver cirrhosis in use of feeding tube. A descriptive research was carried out in a Brazilian Hospital with 20 adult patients. Systematic data collection utilized the Conceptual Model of Wanda Horta, the first nurse to introduce the concept of Nursing Process in Brazil. The six phases of the nursing diagnostic reasoning proposed by Risner were used;nursing diagnoses were described according to NANDA-I taxonomy II. Patients were mainly male;half of them were middle age adults;they had an average of 12.8 nursing diagnoses labels;and the most frequent were: risk for aspiration and risk for infection. Nurses needed to develop effective skills to properly diagnose in order to provide safe care and improve patient outcomes.

Modelling Animal Activity as Curves: An Approach Using Wavelet-Based Functional Data Analysis

Open Journal of Statistics 2017年第2期7卷 203-215页

Temporal activity patterns in animals emerge from complex interactions between choices made by organisms as responses to biotic interactions and challenges posed by external factors. Temporal activity pattern is an inherently continuous process, even being recorded as a time series. The discreteness of the data set is clearly due to data-acquisition limitations rather than a true underlying discrete nature of the phenomenon itself. Therefore, curves are a natural representation for high-frequency data. Here, we fully model temporal activity data as curves integrating wavelets and functional data analysis, allowing for testing hypotheses based on curves rather than on scalar and vector-valued data. Temporal activity data were obtained experimentally for males and females of a small-bodied marsupial and modelled as wavelets with independent and identically distributed errors and dependent errors. The null hypothesis of no difference in temporal activity pattern between male and female curves was tested with functional analysis of variance (FANOVA). The null hypothesis was rejected by FANOVA and we discussed the differences in temporal activity pattern curves between males and females in terms of ecological and life-history attributes of the reference species. We also performed numerical analysis that shed light on the regularity properties of the wavelet bases used and the thresholding parameters.

The Benefits of SGLT2 Inhibitors in Cardiovascular Prevention, Glycemic Control and Weight Loss, in the Treatment of Diabetes

引用

Open Journal of Endocrine and Metabolic Diseases 2016年第1期6卷 87-94页

作者： Bruna de Souza Faustino Alberto dos reis Costa Junior Letícia Nascimento Medeiros Bortolon Larissa Bianca Paiva Cunha de Sá Denise Rosso Tenório Wanderley Rocha Alberto Krayyem Arbex Division of Endocrinology IPEMED Medical School Rio de Janeiro Brazil Visiting Scientist of the Harvard School of Public Health Harvard University Boston USA

The sodium and glucose co-transporter inhibitors type 2 (SGLT2) comprises a new class of hypoglycemic drugs to control type 2 diabetes mellitus, in an attempt to add new non-existing benefits to the so far arising classes. Regarding this new class of drugs, represented by dapaglifozin, canaglifozin and empaglifozin, it is important to highlight the benefits brought by these medications to combat hyperglycemia with insulin-independent mechanisms that are beyond glucose reduction, such as cardiovascular events prevention, reduction in HbA1c, weight loss and blood pressure lowering. Recently, a relevant study (Empa-Reg) brought hope and set the spotlight on the prevention of cardiac events among diabetic patients, which is the main cause of mortality within this group. However, despite coming out as a good treatment option, SGLT2 inhibitors are under constant clinical research and, as a new drug, it should be carefully carried out regarding the long-term effects of glycosuria and other possible side effects, such as the observed increase in the incidence of bladder, breast cancer and bone fractures, which require further studies. Therefore, these compounds might represent a landmark approach for the treatment of diabetes.

Influence of MIG/MAG Welding Process on Mechanical and Pitting Corrosion Behaviors on the Super-Duplex Stainless Steel SAF 2507 Welded Joints

引用

Materials Sciences and Applications 2018年第2期9卷 228-245页

作者： Bruno Leonardy S. Lopes Samuel F. Rodrigues Eden S. Silva Gedeon S. reis Waldemir dos P. Martins Juvenilson Costa Damascena Valdemar S. Leal Graduate Program in Materials Engineering Federal Institute of Education Science and Technology of Maranh&atilde o—IFMA S&atilde o Luís MA Brazil Engineering Coordination Universidade UNICEUMA S&atilde o Luís MA Brazil

The main objective of this research is to better understand the correlation between the constituent phases presented in the super-duplex steel SAF 2507 when it is under welding process by arc shielding gas MIG-MAG (Metal Inert Gas-Metal Active Gas). Conventional short circuit transfer and derivative STT (Surface Tension Transfer) using the 2594 welding wire as a filler metal and the effects on welding power in hardness, toughness and pitting corrosion are considered here. The results showed that the welding energy (Ew) changed the α/γ-phase’s balance and occasionally formed σ-phase in ferrite grain boundaries which led to changes in hardness, toughness and pitting corrosion resistance in molten zone (MZ), heat activated zone (HAZ) and metal base regions (MB). Furthermore, the increased amount of γ-phase improved the pitting corrosion resistance index (PRENγ) mainly in the MZ. This is due to decrease of α-phase fraction and formation of coarser grains, for higher welding energy. The toughness in the MZ decreased with less formation of γ-phase, coalescence of ferritic grains and localized formation of σ-phase, raising the hardness in the HAZ when the welding energy was lower.
