RESUMO

Resumo A invisibilidade é uma questão que necessita de maior atenção entre os profissionais de saúde, pois algumas atividades na Atenção Primária passam despercebidas. Um exemplo é a oferta de terapias complementares, cuja implementação tem sido frágil e, consequentemente, pode ser invisibilizada no Sistema Único de Saúde. Este estudo visa compreender os fatores que contribuem para a invisibilidade pública das Práticas Integrativas e Complementares na Atenção Primária. Trata-se de uma pesquisa descritiva, exploratória e qualitativa, envolvendo entrevistas semiestruturadas com 20 profissionais na Região Metropolitana de Goiânia. A análise de conteúdo temática foi aplicada às entrevistas, revelando elementos que indicam a invisibilidade pública dessas práticas, como a falta de discussão nas reuniões de equipe, a desuniformidade no registro nos prontuários dos usuários e a baixa priorização na implementação. Nas entrevistas, a humilhação social, produto da invisibilidade pública, também pode ser percebida devido à sobrecarga, constrangimentos e falta de espaço físico para a oferta das práticas aos usuários.

Abstract Invisibility is an issue that requires more attention among healthcare professionals, as some activities in Primary Care go unnoticed. One example is the offer of complementary therapies, whose implementation has been frail and, consequently, can be overlooked in the Unified Health System. This study aims to understand the factors contributing to the public invisibility of Integrative and Complementary Practices in Primary Care. It is a descriptive, exploratory, and qualitative research involving semi-structured interviews with 20 professionals in the Metropolitan Region of Goiânia. Thematic content analysis was applied to the interviews, revealing elements indicating the public invisibility of these practices, such as insufficient discussion in team meetings, inconsistency in the recording in user files, and low prioritization in implementation. In the interviews, social humiliation, a product of public invisibility, can also be perceived due to overload, embarrassments, and lack of physical space for the provision of practices to the users. It is concluded that Integrative and Complementary Practices are often overlooked in Primary Care.

RESUMO

OBJECTIVE: Premature ovarian insufficiency (POI) affects up to 3% of the global female population, influencing metabolic, cardiovascular, and reproductive health. Medical expertise in diagnosis, effects, and treatment strategies, particularly for gynecologists, is crucial for ensuring improved healthcare for women. The objective of this study is to assess the state of medical knowledge regarding the diagnosis, treatment, and follow-up of POI among Brazilian gynecologists. METHODS: A cross-sectional study was conducted using online questionnaires administered to 16,000 members of the Brazilian Federation of Gynecology and Obstetrics. RESULTS: In total, 460 questionnaires were received from gynecologists who had an average age of 44.49 ± 12.57 years and 19.37 ± 12.95 years of professional experience. Fifty-three percent of gynecologists diagnosed POI correctly, and 49% requested karyotype analysis, while fewer than 10% identified all POI etiologies. Over 90% of gynecologists understood the long-term consequences of POI for bone and cardiovascular health. Despite being a consequence of hypoestrogenism, hormone therapy was recommended only by 20% of doctors, with no more than 50% of them prescribing appropriate doses for young women. Regarding self-perception, 60% of gynecologists declared deficient knowledge regarding how to offer care and guidance to women, with hormone therapy being reported as the most important reason (47%). CONCLUSIONS: Current concepts and guidelines for POI are not adequately understood or applied in Brazilian clinical practice, leading to suboptimal care.

RESUMO

A doença de Madelung é caracterizada pelo acúmulo simétrico e difuso de tecido adiposo com crescimento tumoral lento e progressivo. Neste relato de caso, um paciente portador dessa síndrome foi atendido no Hospital das Clínicas, em Recife, PE, com o objetivo de realizar uma redução do conteúdo lipomatoso através de lipectomia. O paciente apresentava volumosas massas de tecido adiposo elástico ao redor do pescoço e região supraclavicular e a proposta terapêutica consistiu em uma cirurgia em dois tempos, com lipoaspiração e lipectomia cervical anterior, seguida de lipoaspiração e lipectomia cervical posterior. Antes da cirurgia, foi solicitado um parecer cardiológico, que indicou um risco intermediário, mas não contraindicou o procedimento. Após 4 dias da cirurgia, o paciente apresentou equimoses e edema periférico na ferida operatória cervical, porém estava assintomático. As técnicas de lipectomia e lipoaspiração são consideradas os métodos de tratamento mais eficazes para a doença de Madelung. No entanto, a escolha da cirurgia deve ser baseada em uma avaliação abrangente da gravidade da doença, localização da massa e expectativas do paciente, uma vez que ambas as técnicas possuem vantagens e desvantagens.

Madelung's disease is characterized by the symmetric and diffuse accumulation of adipose tissue with slow and progressive tumor growth. In this case report, a patient with this syndrome was treated at Hospital das Clínicas, in Recife, PE, to reduce the lipomatous content through a lipectomy. The patient presented large masses of elastic adipose tissue around the neck and supraclavicular region and the therapeutic proposal consisted of a two-stage surgery, with liposuction and anterior cervical lipectomy, followed by liposuction and posterior cervical lipectomy. Before surgery, a cardiological opinion was requested, which indicated an intermediate risk but did not contraindicate the procedure. Four days after surgery, the patient presented bruises and peripheral edema in the cervical surgical wound but was asymptomatic. Lipectomy and liposuction techniques are considered the most effective treatment methods for Madelung disease. However, the choice of surgery should be based on a comprehensive assessment of the severity of the disease, location of the mass, and patient expectations, as both techniques have advantages and disadvantages.

RESUMO

Semantic verbal fluency (SVF) impairment is present in several neurological disorders. Although activation in SVF-related areas has been reported, how these regions are connected and their functional roles in the network remain divergent. We assessed SVF static and dynamic functional connectivity (FC) and effective connectivity in healthy participants using functional magnetic resonance imaging. We observed activation in the inferior frontal (IFG), middle temporal (pMTG) and angular gyri (AG), anterior cingulate (AC), insular cortex, and regions of the superior, middle, and medial frontal gyri (SFG, MFG, MidFG). Our static FC analysis showed a highly interconnected task and resting state network. Increased connectivity of AC with the pMTG and AG was observed for the task. The dynamic FC analysis provided circuits with connections similarly modulated across time and regions related to category identification, language comprehension, word selection and recovery, word generation, inhibition of speaking, speech planning, and articulatory planning of orofacial movements. Finally, the effective connectivity analysis provided a network that best explained our data, starting at the AG and going to the pMTG, from which there was a division between the ventral and dorsal streams. The SFG and MFG regions were connected and modulated by the MidFG, while the inferior regions formed the ventral stream. Therefore, we successfully assessed the SVF network, exploring regions associated with the entire processing, from category identification to word generation. The methodological approach can be helpful for further investigation of the SVF network in neurological disorders.

RESUMO

Rhodococcus erythropolis bacterium is known for its remarkable resistance characteristics that can be useful in several biotechnological processes, such as bioremediation. However, there is scarce knowledge concerning the behavior of this strain against different metals. This study sought to investigate the behavior of R. erythropolis ATCC 4277 against the residue of chalcopyrite and e-waste to verify both resistive capacities to the metals present in these residues and their potential use for biomining processes. These tests were carried out in a stirred tank bioreactor for 48 h, at 24ºC, pH 7.0, using a total volume of 2.0 L containing 2.5% (v/v) of a bacterial pre-culture. The pulp density of chalcopyrite was 5% (w/w), and agitation and oxygen flow rates were set to 250 rpm and 1.5 LO2 min-1, respectively. On the other hand, we utilized a waste of computer printed circuit board (WPCB) with a pulp density of 10% (w/w), agitation at 400 rpm, and an oxygen flow rate of 3.0 LO2 min-1. Metal concentration analyses post-fermentation showed that R. erythropolis ATCC 4277 was able to leach about 38% of the Cu present in the chalcopyrite residue (in ~ 24 h), and 49.5% of Fe, 42.3% of Ni, 27.4% of Al, and 15% Cu present in WPCB (in ~ 24 h). In addition, the strain survived well in the environment containing such metals, demonstrating the potential of using this bacterium for waste biomining processes as well as in other processes with these metals.

RESUMO

OBJECTIVES: Colorectal endoscopic submucosal dissection (ESD) is a technically complex procedure. The scissor knife mechanism may potentially provide easier and safer colorectal ESD. The aim of this meta-analysis is to evaluate the efficacy and safety of scissor-assisted vs. conventional ESD for colorectal lesions. METHODS: A search strategy was conducted in MEDLINE, Embase, and Lilacs databases from January 1990 to November 2023 according to PRISMA guidelines. Fixed and random-effects models were used for statistical analysis. Heterogeneity was assessed using I2 test. Risk of bias was assessed using the ROBINS-I and RoB-2 tools. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool. RESULTS: A total of five studies (three retrospective and two randomized controlled trials, including a total of 1575 colorectal ESD) were selected. The intraoperative perforation rate was statistically lower (risk difference [RD] -0.02; 95% confidence interval [CI] -0.04 to -0.01; P = 0.001; I2 = 0%) and the self-completion rate was statistically higher (RD 0.14; 95% CI 0.06, 0.23; P = 0.0006; I2 = 0%) in the scissor-assisted group compared with the conventional ESD group. There was no statistical difference in R0 resection rate, en bloc resection rate, mean procedure time, or delayed bleeding rate between the groups. CONCLUSION: Scissor knife-assisted ESD is as effective as conventional knife-assisted ESD for colorectal lesions with lower intraoperative perforation rate and a higher self-completion rate.

RESUMO

We characterized the neurocognitive profile of communed-based individuals and unaffected siblings of patients with psychosis from Brazil reporting psychotic experiences (PEs). We also analyzed associations between PEs and the intra and inter-functional connectivity (FC) in the Default Mode Network (DMN), the Fronto-Parietal Network (FPN) and the Salience Network (SN) measured by functional magnetic resonance imaging. The combined sample of communed-based individuals and unaffected siblings of patients with psychosis comprised 417 (neurocognition) and 85 (FC) volunteers who were divided as having low (<75th percentile) and high (≥75th percentile) PEs (positive, negative, and depressive dimensions) assessed by the Community Assessment of Psychic Experiences. The neurocognitive profile and the estimated current brief intellectual quotient (IQ) were assessed using the digit symbol (processing speed), arithmetic (working memory), block design (visual learning) and information (verbal learning) subtests of Wechsler Adult Intelligence Scale-third edition. Logistic regression models were performed for neurocognitive analysis. For neuroimaging, we used the CONN toolbox to assess FC between the specified regions, and ROI-to-ROI analysis. In the combined sample, high PEs (all dimensions) were related to lower processing speed performance. High negative PEs were related to poor visual learning performance and lower IQ, while high depressive PEs were associated with poor working memory performance. Those with high negative PEs presented FPN hypoconnectivity between the right and left lateral prefrontal cortex. There were no associations between PEs and the DMN and SN FC. Brazilian individuals with high PEs showed neurocognitive impairments like those living in wealthier countries. Hypoconnectivity in the FPN in a community sample with high PEs is coherent with the hypothesis of functional dysconnectivity in schizophrenia.

RESUMO

INTRODUCTION: Delays in prehospital care attributable to the call-taking process can often be traced back to miscommunication, including uncertainty around the call location. Geolocation applications have the potential to streamline the call-taking process by accurately identifying the caller's location. OBJECTIVE: To develop and validate an application to geolocate emergency calls and compare the response time of calls made via the application with those of conventional calls made to the Brazilian Medical Emergency System (Serviço de Atendimento Médico de Urgência-SAMU). METHODS: This study was conducted in two stages. First, a geolocating application for SAMU emergency calls (CHAMU192) was developed using a mixed methods approach based on design thinking and subsequently validated using the System Usability Scale (SUS). In the second stage, sending time of the geolocation information of the app was compared with the time taken to process information through conventional calls. For this, a hypothetical case control study was conducted with SAMU in the Maringá, Paraná, Brazil. A control group of 350 audio recordings of emergency calls from 2019 was compared to a set of test calls made through the CHAMU192 app. The CHAMU192 group consisted of 201 test calls in Maringá. In test calls, the location was obtained by GPS and sent to the SAMU communication system. Comparative analysis between groups was performed using the Mann-Whitney test. RESULTS: CHAMU192 had a SUS score of 90, corresponding to a "best imaginable" usability rating. The control group had a median response time of 35.67 seconds (26.00-48.12). The response time of the CHAMU192 group was 0.20 (0.15-0.24). CONCLUSION: The use of the CHAMU192 app by emergency medical services could significantly reduce response time. The results demonstrate the potential of app improving the quality and patient outcomes related to the prehospital emergency care services.

RESUMO

In Brazil, the COVID-19 burden was substantial, and risk factors associated with higher in-hospital mortality rates have been extensively studied. However, information on short-term all-cause mortality and the factors associated with death in patients who survived the hospitalization period of acute SARS-CoV-2 infection is limited. We analyzed the six-month post-hospitalization mortality rate and possible risk factors of COVID-19 patients in a single center in Brazil. This is a retrospective cohort study focused on a six-month follow-up. The exclusion criteria were death during hospitalization, transference to another hospital, and age under 18. We collected data from the charts of all hospitalized patients from March 2020 to December 2020 with a positive RT-PCR test for SARS-CoV-2, resulting in a sample size of 106 patients. The main outcome was death after hospitalization, whereas comorbidities and demographics were evaluated as risk factors. The crude post-hospitalization death rate was 16%. The first 30 days of follow-up had the highest mortality rate. In a Cox regression model for post-hospitalization mortality, previous chronic kidney disease (HR, 4.06, 95%CI 1.46 - 11.30) and longer hospital stay (HR 1.01, 95%CI 1.00 - 1.02) were the only factors statistically associated with death. In conclusion, a high six-month all-cause mortality was observed. Within the six-month follow-up, a higher risk of death was observed for patients who had prior CKD and longer hospital stay. These findings highlight the importance of more intensive medical surveillance during this period.

RESUMO

Resumo Após 15 anos de promulgação da política nacional, muitas unidades de saúde ainda não implantaram as Práticas Integrativas e Complementares em Saúde. As razões para esse afastamento da Atenção Primária à Saúde na Região Metropolitana de Goiânia-GO, Brasil, ainda são desconhecidas. Assim, este estudo objetiva compreender como os gerentes percebem as dificuldades de implantação e implementação das Práticas Integrativas e Complementares em Saúde na Atenção Primária à Saúde. Trata-se de um estudo qualitativo, descritivo e exploratório, realizado com 24 gerentes de unidades básicas de saúde mediante entrevistas semiestruturadas e analisadas segundo a estrutura de conteúdo de Bardin. Os gerentes imputam a impossibilidade da oferta a fatores como sobrecarga do trabalho, falta de apoio financeiro, material e organizacional por parte das secretarias de Saúde, preconceito, infraestrutura inadequada, inexistência de recurso financeiro e insuficiência de formação em serviço. Portanto, concluímos que a implementação das Práticas Integrativas e Complementares em Saúde é incipiente na Atenção Primária à Saúde por conta, principalmente, de barreiras estruturais, organizacionais, culturais e educacionais. Esses resultados podem colaborar na resolução desses obstáculos, para que as Práticas Integrativas e Complementares em Saúde possam ser oferecidas aos usuários do Sistema Único de Saúde de forma mais equânime.

Abstract After 15 years of promulgating the national policy, many health units still have not implemented the Integrative and Complementary Practices. The reasons for this departure from Primary Health Care in the Metropolitan Region of Goiania-GO, Brazil, remain unknown. Thus, this study aims to understand how managers perceive the difficulties of implementing and implementing Integrative and Complementary Health Practices in Primary Health Care. This qualitative, descriptive, and exploratory study was carried out with 24 managers of basic health units through semi-structured interviews, transcribed and analyzed according to Bardin's content structure. Managers attribute the absence of Integrative and Complementary Practices in Primary Health Care to factors such as work overload, lack of support from the health secretariats, prejudice, inadequate infrastructure, lack of financial resources, and insufficient in-service training. Therefore, we conclude that Integrative and Complementary Practices are absent from Primary Health Care, mainly due to structural and organizational barriers. These results may imply the resolution of these obstacles so that Integrative and Complementary Practices can be offered to users of the Unified Health System more equitably.

RESUMO

Objective: Transcranial direct current stimulation (tDCS) has mixed effects for major depressive disorder (MDD) symptoms, partially owing to large inter-experimental variability in tDCS protocols and their correlated induced electric fields (E-fields). We investigated whether the E-field strength of distinct tDCS parameters was associated with antidepressant effect. Methods: A meta-analysis was performed with placebo-controlled clinical trials of tDCS enrolling MDD patients. PubMed, EMBASE, and Web of Science were searched from inception to March 10, 2023. Effect sizes of tDCS protocols were correlated with E-field simulations (SimNIBS) of brain regions of interest (bilateral dorsolateral prefrontal cortex [DLPFC] and bilateral subgenual anterior cingulate cortex [sgACC]). Moderators of tDCS responses were also investigated. Results: A total of 20 studies were included (21 datasets, 1,008 patients), using 11 distinct tDCS protocols. Results revealed a moderate effect for MDD (g = 0.41, 95%CI 0.18-0.64), while cathode position and treatment strategy were found to be moderators of response. A negative association between effect size and tDCS-induced E-field magnitude was seen, with stronger E-fields in the right frontal and medial parts of the DLPFC (targeted by the cathode) leading to smaller effects. No association was found for the left DLPFC and the bilateral sgACC. An optimized tDCS protocol is proposed. Conclusions: Our results highlight the need for a standardized tDCS protocol in MDD clinical trials. Registration number: PROSPERO CRD42022296246.

RESUMO

Treatment-resistant depression (TRD), characterized by the failure to achieve symptomatic remission despite multiple pharmacotherapeutic treatments, poses a significant challenge for clinicians. Electroconvulsive therapy (ECT) is an effective but limited option due to its cognitive side effects. In this context, magnetic seizure therapy (MST) has emerged as a promising alternative, offering comparable antidepressant efficacy with better cognitive outcomes. However, the clinical outcomes and cognitive effects of MST require further investigation. This double-blinded, randomized, non-inferiority study aims to compare the efficacy, tolerability, cognitive adverse effects, and neurophysiological biomarkers of MST with bilateral ECT (BT ECT) in patients with TRD. This study will employ multimodal nuclear magnetic resonance imaging (MRI) and serum neurotrophic markers to gain insight into the neurobiological basis of seizure therapy. Additionally, neurophysiological biomarkers will be evaluated as secondary outcomes to predict the antidepressant and cognitive effects of both techniques. The study design, recruitment methods, ethical considerations, eligibility criteria, interventions, and blinding procedures are described. The expected outcomes will advance the field by offering a potential alternative to ECT with improved cognitive outcomes and a better understanding of the underlying pathophysiology of depression and antidepressant therapies.

RESUMO

This article proposes a system for Content-Based Image Retrieval (CBIR) using stochastic distance for Synthetic-Aperture Radar (SAR) images. The methodology consists of three essential steps for image retrieval. First, it estimates the roughness (α^) and scale (γ^) parameters of the GI0 distribution that models SAR data in intensity. The parameters of the model were estimated using the Maximum Likelihood Estimation and the fast approach of the Log-Cumulants method. Second, using the triangular distance, CBIR-SAR evaluates the similarity between a query image and images in the database. The stochastic distance can identify the most similar regions according to the image features, which are the estimated parameters of the data model. Third, the performance of our proposal was evaluated by applying the Mean Average Precision (MAP) measure and considering clippings from three radar sensors, i.e., UAVSAR, OrbiSaR-2, and ALOS PALSAR. The CBIR-SAR results for synthetic images achieved the highest MAP value, retrieving extremely heterogeneous regions. Regarding the real SAR images, CBIR-SAR achieved MAP values above 0.833 for all polarization channels for image samples of forest (UAVSAR) and urban areas (ORBISAR). Our results confirmed that the proposed method is sensitive to the degree of texture, and hence, it relies on good estimates. They are inputs to the stochastic distance for effective image retrieval.

RESUMO

Aim: We sought to create and describe a self-made simulator designed and created for teaching purposes: a high-fidelity ultrasound phantom for demonstrating antral follicle count, ultrasound supervision of controlled of ovarian stimulation, and ultrasound-guided oocyte retrieval. Materials and methods: The uterus and ovaries of the ultrasound phantom were made from beef tongue, a male condom, latex gloves, cotton suture threads, bi-distilled water, and ultrasound gel. The components were placed in a pelvis created using three-dimensional (3D) printing. The phantom was presented to and evaluated by a group of 14 physicians pursuing a postgraduate course in reproductive medicine. Two training stations were structured: one to simulate antral follicle count and controlled ovarian stimulation and the other to simulate ultrasound-guided oocyte retrieval. Future specialists were requested to complete a feedback questionnaire evaluating the self-made simulator and the two practice stations. Results: The transvaginal ultrasound phantom was successfully created, making it possible to simulate antral follicle count, ultrasound control of ovarian hyperstimulation, and oocyte retrieval, and to capture ultrasound images. A review of the answers provided in the feedback questionnaire showed that the phantom had a good appearance and design, was realistic, helped to improve motor coordination, and could be a useful tool in the training of specialists in assisted reproduction. Conclusion: This phantom was designed to enable instruction and practice in the evaluation of ovarian follicles and ultrasound-guided oocyte retrieval in a supervised training environment. This self-made simulator is proposed as a training tool that could be included in the curricular structure of residency and postgraduate programs in reproductive medicine.

RESUMO

miRNAs, a class of small non-coding RNAs, play a role in post-transcriptional gene expression. Therefore, this study aimed to conduct a systematic review of miRNAs associated with GDM to build a panel of miRNAs. A bibliographic search was carried out in the PubMed/Medline, Virtual Health Library (VHL), Web of Science, and EMBASE databases, selecting observational studies in English without time restriction. The protocol was registered on the PROSPERO platform (number CRD42021291791). Fifty-five studies were included in this systematic review, and 82 altered miRNAs in GDM were identified. In addition, four miRNAs were most frequently dysregulated in GDM (mir-16-5p, mir-20a-5p, mir-222-3p, and mir-330-3p). The dysregulation of these miRNAs is associated with the mechanisms of cell cycle homeostasis, growth, and proliferation of pancreatic ß cells, glucose uptake and metabolism, insulin secretion, and resistance. On the other hand, identifying miRNAs associated with GDM and elucidating its main mechanisms can assist in the characterization and definition of potential biomarkers for the diagnosis and treatment of GDM.
