title: Coherence in the thematic representation of scientific articles in the public health area

description: Abstract The research investigates the semantic coherence in the indexing of journal articles in the public health area, in Portuguese, indexed in the Scientific Production Repository of the National School of Public Health Sergio Arouca (ENSP) of the Oswaldo Cruz Foundation (Fiocruz) aiming to contribute to the semantic interoperability between the repositories of this Foundation. For that, 10 papers from Brazilian scientific journals, published in open access between 2012-2014 and registered in the Scientific Production Repository of ENSP / Fiocruz, were analyzed. The articles were processed in the software RankWord and WordSmith 6.0, after applying the laws of Zipf and Goffman Transition Point to identify the terms of high semantic load of texts. The terms selected in each article were compared in the 5 (five) indicators used in the research: Goffman's T region; Expressions WordSmith 6.0, Keywords; DeCS (Descriptors in Health Sciences) and Title. The results were compiled using the discursive plane of sentences, with emphasis on terms used as foregrounding and in terms used as background, helping to verify the degree of coherence between the articles. The data collected reveal a low degree of semantic coherence in most articles studied. Thus, we suggest an investigation with an expanded sample to confirm the data obtained, especially when dealing with articles published in Portuguese in the area of health and its importance in brazilian scientific communication.

title: Effect of Chemical Composition on the Microstructure, Hardness and Electrical Conductivity Profiles of the Ag-Bi-Ge Alloys

description: Microstructure, hardness and electrical properties of the selected ternary Ag-Bi-Ge alloys were investigated in this study. Isothermal sections of the Ag-Bi-Ge system at 25, 100 and 500 °C have been extrapolated using optimized thermodynamic parameters from literature and experimentally investigated. Performed experiments were optical microscopy, scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS), X-ray powder diffraction (XRD), hardness measurements by Brinell method and electrical conductivity measurements. EDS results were compared with predicted phase equilibria and good overall agreement between experimental and calculated values was obtained. XRD results were also in agreement with predicted phase equilibria. Hardness and electrical conductivity of selected alloys were measured and by using appropriated mathematical model these properties were predicted in the whole composition range.

title: Legal abortion in Brazil: systematic review of the scientific production, 2008-2018

description: Abstract: Previous reviews on the subject of abortion in Brazil have estimated one million procedures per year but did not address legal abortion. This systematic review sought to update knowledge regarding legal abortion in terms of service and women’s profile, student and doctor knowledge, situations of anencephaly and severe malformations. We searched MEDLINE and LILACS for articles published in all languages between 2008 and 2018. Article quality was assessed using the Joanna Briggs Institute instruments. Search, selection, quality assessment and data extraction were carried out independently by two researchers. We selected 20 articles, 11 on the knowledge and opinion of medical professionals (4 articles) and students (7 articles) revealing a less-than-ideal level of knowledge and a high degree of objection of conscience. Six studies on women who use legal abortion services found that they are young, single and that the main demand was for pregnancy resulting from rape. When women were younger and single and when the aggressor was someone close to them, there were delays in seeking care. Three studies on severe malformation found around 40% of court authorizations. In cases for which no authorization was given, the evolution of pregnancies was complicated and deliveries were done through cesarean sections. Only one article addressed legal abortion services, showing that 37 of the 68 that had been registered were active, lack of services in seven states and concentration in capitals. Knowledge regarding legal abortion is still scarce, the demand for the procedure is repressed and medical training is deficient with regard to this subject.

title: Unsafe abortion in Brazil: a systematic review of the scientific production, 2008-2018

description: This study sought to update knowledge on unsafe abortion in Brazil. We carried out a systematic review with study search and selection on MEDLINE and LILACS, with no language restriction, from 2008 to 2018. We evaluated article quality using the Joanna Briggs Institute instruments. We evaluated 50 articles. The prevalence of induced abortion in Brazil was estimated by a direct method to be 15% in 2010 and 13% in 2016. Higher prevalences were observed in more socially vulnerable populations. There was a decrease in the ratio of induced abortions by 1,000 women of reproductive age in the period 1995-2013, reaching 16 per 1,000 in 2013. Half of all women reported using medications for terminating pregnancies and the number of hospital admissions due to complications from abortion, especially severe complications, decreased from 1992 to 2009. Maternal morbimortality from abortion had a reduced frequency but reached high values in specific contexts. It is likely that maternal deaths from abortion are under-reported. Common mental disorders during pregnancy and postpartum depression were more frequent among women who unsuccessfully attempted to induce an abortion. Findings indicate that abortion is frequently used in Brazil, especially in less-developed regions and by more socially-vulnerable women. Access to safer methods probably contributed to the reduction in hospitalizations due to complications and to the reduction in morbimortality from abortion. However, half of all women still resort to other methods and the number of admissions due to complications from abortion is still high.

title: Infrared thermography for the analysis of ocular surface temperature after phacoemulsification

description: ABSTRACT Purpose: In this study, we present our observations on changes in the surface temperature of the cornea, eye, and orbital cavity after cataract surgery. Methods: A total of 39 patients who underwent cataract surgery based on phacoemulsification were enrolled. Temperature was measured at the center of the cornea, on the eye surface, and in orbital cavities using the FLIR T640 thermal imaging camera at days 1, 14, and 28 after cataract phacoemulsification and compared with preoperative baseline values. Results: The mean value of ocular surface temperature of the orbital cavity 14 days after cataract surgery was significantly different compared with the preoperative temperature (p£0.05). Temperature of the investigated areas showed a reduction, with the greatest decrease on day 14 after surgery, followed by an increase on day 28 after surgery, which was comparable to the temperature measured prior to surgery. Conclusions: The reduction in ocular surface temperature toward the end of post-cataract surgery follow-up may be associated with increased instability of the tear film after phacoemulsification. Therefore, patient awareness regarding the possibility of clinical symptoms of dry eye syndrome during the first month after surgery should be part of clinical management of cataract surgery. Ocular surface temperature did not increase after cataract surgery, suggesting the absence of significant inflammation, and the temperature about 1 month after cataract surgery was comparable to that before surgery. Nevertheless, the negative correlation between age and ocular surface temperature should be of concern in the elderly.

title: Long-term comparison of the efficacies of internal and external browpexy combined with blepharoplasty

description: ABSTRACT Purpose: To perform a long-term comparison of the quantitative efficacy of internal and external browpexy in combination with upper-lid blepharoplasty based on lateral and central eyebrow positions. Methods: This retrospective study evaluated internal and external browpexy with upper-lid blepharoplasty surgeries that were performed during the period between January 2012 and December 2017 in the oculoplastic surgery department of our hospital. Patients who had undergone periorbital and forehead surgery, who had ophthalmologic or neurological diseases, and who were Botox users were not included in the study. Preoperative and postoperative measurements were made on photographs taken in the same position. The distances from the pupil center and from the point of intersection between the horizontal line passing through the pupil and the vertical line passing through the lateral canthus to the upper eyebrow borders were measured. Photogrammetric analysis of eyebrow position was analyzed using Corel Draw software. Results: Preoperative and postoperative photographs of 70 eyelids were analyzed. Measurements were taken 24 months after surgery. Mean elevations of 2.10 and 3.19 mm were observed in the central region and lateral regions, respectively, in the internal browpexy group. These elevations were 2.66 and 3.03 mm in the external browpexy group and 0.48 and 0.55 mm in the control group. Eyebrow elevations in the central and lateral regions were not significantly different from baseline in the control group (p=0.126 and p=0.25). Internal and external browpexy showed statistically similar elevation values in the central and lateral regions (p=0.636 and p=0.342). Conclusions: External and internal browpexy surgery afforded adequate and similar elevations of the central and lateral brow, which were significantly different from those in the standard blepharoplasty group during long-term follow-up.

title: Survey among retina specialists in Brazil about inflammatory reactions after intravitreal antiangiogenic therapy

description: ABSTRACT Purpose: This survey aimed at assessing the clinical characteristics of patients with inflammatory reactions after intravitreal injection of antiangiogenic agents and the techniques employed by Brazilian retina specialists. Methods: We sent an 18-item questionnaire electronically to retina specialists who are using antiangiogenic agents. We got the responses between September 21 and December 23, 2018. Results: A total of 58 retina specialists participated. Most of them were from Southeastern Brazil (50%), 82.8% were dedicated to both medical and surgical practices, and 86.2% had practiced for more than 5 years. Respondents reported a mean number of 2.14 ± 1.63 patients with inflammation, 44.8% with panuveitis, and 79.3% with onset of symptoms within 72 h. Specialists used aflibercept (53.4%), bevacizumab (29.3%), and ranibizumab (27.6%). Most patients were treated with steroid drops (70.7%), and their inflammation subsided after 11.5 ± 11.5 days (86.2% lacked irreversible complications). The specialists blamed the syringe as the cause of the inflammation in 25.9% of the cases, 41.4% used Becton-Dickinson Ultra-Fine syringes, 43.1% injected the drug at room temperature, and 37.9% removed the air (53.4% by flicking the syringe). Most specialists did not detect silicone oil (67.2%), but 17.2% of them performed vitrectomies to remove vitreous opacities. Finally, 44.8% of specialists injected the same antiangiogenic agent in an eye with prior inflammatory reaction without further inflammation. Conclusions: Most specialists reported cases of early-onset inflammation after intravitreal injection of antiangiogenic agents. The incidence of irreversible complications was low. Aflibercept was the most common agent used. The causes of inflammation remain unknown, but we formulated some relevant hypotheses.

title: Resources, objectives and guidelines in a Psychosocial Care Network structure

description: ABSTRACT Objective: to analyze a Psychosocial Care Network structure, based on the compromise of its resources and meeting objectives and guidelines recommended in Ordinance 3,088/2011. Method: an empirical, quantitative study with 123 primary care professionals, psychosocial and emergency care, who work at Western Network of the city of São Paulo. Questionnaires and statistical analysis were applied through the Exact Fisher’s test with 5% significance considering p= &lt;0.05. Results: there is compromise of physical resources in the absence of mental health beds in a general hospital (p=0.047); of technological resources in the lack of discussion forums (p=0.036); of human resources in number of teams (p=0.258); and of financial resources (p=0.159). Psychosocial care is the one that most meets the objectives and guidelines. Conclusion: there are insufficient physical, technological, human, and financial resources for the work articulated in the three care modalities that are heterogeneous in terms of meeting the objectives and guidelines.

title: Clinical Competence in ST-segment Elevation Myocardial Infarction Management by Recently Graduated Physicians Applying for a Medical Residency Program

description: Abstract Background: A significant reduction in the morbidity and mortality related to ST-segment elevation myocardial infarction (STEMI) has been achieved with the development of reperfusion therapies. Early diagnosis and correct initial management are important to ensure this benefit. In Brazil, recent graduates in medicine are responsible for a large part of the initial care provided for these patients. Objective: To assess the clinical competence in the diagnosis and initial treatment of STEMI by newly graduated physicians applying for a medical residency program. Methods: We assessed the performance of 771 applicants for the direct entry selection process of the FMRP-USP Clinical Hospital Medicine Residency Program, performed in a simulated setting of STEMI, with professional actors and medical evaluators, using a standardized checklist following the recommendations of the Brazilian Guidelines for the management of this disease. Results: The general performance score presented a median of 7 and an interquartile range of 5.5-8.0. In relation to the items assessed: 83% required ECG monitoring, 57% requested the insertion of a peripheral venous access catheter, 95% administered acetylsalicylic acid, 80% administered a second antiplatelet agent (p2y12 inhibitor), 66% administered nitrate, 71% administered morphine, 69% recognized the diagnosis of STEMI, 71% assessed the pain duration, 63% recognized the need for immediate transfer, 34% showed adequate communication skills and only 25% insisted on the transfer even in case of non-availability of beds. Conclusions: The initial diagnosis and management of STEMI need to be improved in medical undergraduate courses and inserted into the reality of the hierarchical network structure of the Brazilian Unified Health System (SUS).
