RESUMEN

Objective: The aim of the present study is to identify a more reliable reference point in three-dimensional cephalometric analysis to replace the Porion point used in two-dimensional analysis, enhancing the accuracy of assessments. Methods: The methodology assessed potential alternative landmarks for three-dimensional cephalometric analysis. Utilizing a segmenting technique, anatomical landmarks were accurately pinpointed from the external acoustic meatus of 26 Cone Beam Computed Tomography (CBCT) scans. These landmarks were chosen for their clear and unambiguous detectability. To assess reproducibility, each landmark was replicated twice with a one-week interval by a master's student. Reproducibility was quantitatively evaluated by analyzing the absolute difference per axis. Results: Five possible candidate landmarks were identified: the most anterior, posterior, superior, and inferior points of the external acoustic meatus (EAM) and a notch delineating the epitympanic recess. The reproducibility of pinpointing these landmarks ranged from 0.56 mm to 2.2 mm. The absolute mean differences between measurements were 0.46 mm (SD 0.75) for the most anterior point, 0.36 mm (SD 0.44) for the most posterior point, 0.25 mm (SD 0.26) for the most superior point, 1.11 mm (SD 1.03) for the most inferior point, and 0.78 mm (SD 0.57) for the epitympanic notch. Conclusions: The most superior point of the EAM might successfully replace the Porion as an anatomical reference.

RESUMEN

Status epilepticus (SE) is a medical emergency associated with high mortality and morbidity. Na+, K+-ATPase, is a promising therapeutic target for SE, given its critical role in regulation of neuron excitability and cellular homeostasis. We investigated the effects of a Na+, K+-ATPase-activating antibody (DRRSAb) on short-term electrophysiological and behavioral consequences of pilocarpine-induced SE. Rats were submitted to pilocarpine-induced SE, followed by intranasal administration (2 µg/nostril). The antibody increased EEG activity following SE, namely, EEG power in theta, beta, and gamma frequency bands, assessed by quantitative analysis of EEG power spectra. One week later, DRRSAb-treated animals displayed less behavioral hyperreactivity in pick-up tests and better performance in novel object recognition tests, indicating that the intranasal administration of this Na+, K+-ATPase activator immediately after SE improves behavioral outcomes at a later time point. These results suggest that Na+, K+-ATPase activation warrants further investigation as an adjunctive therapeutic strategy for SE.

RESUMEN

Objective: In this study, we thoroughly analyzed how balanced the left and right sides of the external acoustic meatus are. Despite previous research focusing on the consistency of various anatomical features and the shape of the external acoustic meatus, which are important for creating guidelines to assess changes in the skull, there hasn't been enough attention given to how symmetrical it is. Our aim was to fill this gap by providing a comprehensive examination of its bilateral symmetry, which is crucial for accurate evaluations in dentistry and medicine. Study design: After importing 26 cone-beam computed tomography scans of patients into the ITK-SNAP 3D imaging software, a midsagittal plane was set up as the plane of symmetry for each patient. With this plane, we compared the positions of the most superior and inferior left and right points of the external acoustic meatus. We also compared the lengths and depths of the lines connecting the two points. Results: There were no statistically significant differences in the position, length, or depth of the external acoustic meatus between the right and left halves of the skull. Conclusion: Specific points on the skull, such as the highest (most superior MSP) and lowest (most inferior MIP) points, demonstrated a high degree of symmetry in the left and right halves. They demonstrated sufficient symmetry to establish a reliable reference plane. Along with the trajectory connecting them, these points can serve as viable alternatives to the Porion for three-dimensional imaging.

RESUMEN

Historically, all efforts against tuberculosis were focused on rapid diagnosis and effective treatment to break the chain of transmission of Mycobacterium tuberculosis. However, in the last few years, more and more evidence has been found on the dramatic consequences of the condition defined as post-tuberculosis lung disease (PTLD). Approximately one third of patients surviving pulmonary tuberculosis face considerable ongoing morbidities, including respiratory impairment, psychosocial challenges, and reduced health-related quality of life after treatment completion. Given the important global and local burden of tuberculosis, as well as the estimated burden of PTLD, the development of a consensus document by a Brazilian scientific society-Sociedade Brasileira de Pneumologia e Tisiologia (SBPT)-was considered urgent for the prevention and management of this condition in order to allocate resources to and within tuberculosis services appropriately and serve as a guide for health care professionals. A team of eleven pulmonologists and one methodologist was created by the SBPT to review the current evidence on PTLD and develop recommendations adapted to the Brazilian context. The expert panel selected the topics on the basis of current evidence and international guidelines. During the first phase, three panel members drafted the recommendations, which were divided into three sections: definition and prevalence of PTLD, assessment of PTLD, and management of PTLD. In the second phase, all panel members reviewed, discussed, and revised the recommendations until a consensus was reached. The document was formally approved by the SBPT in a special session organized during the 2023 SBPT Annual Conference.

RESUMEN

Understanding microRNA (miRNA) functions has been hampered by major difficulties in identifying their biological target(s). Currently, the main limitation is the lack of a suitable strategy to identify biologically relevant targets among a high number of putative targets. Here we provide a proof of concept of successful de novo (i.e. without prior knowledge of its identity) miRNA phenotypic target (i.e. target whose de-repression contributes to the phenotypic outcomes) identification from RNA-seq data. Using the medaka mir-202 knock-out (KO) model in which inactivation leads to a major organism-level reproductive phenotype, including reduced egg production, we introduced novel criteria including limited fold-change in KO and low interindividual variability in gene expression to reduce the list of 2853 putative targets to a short list of 5. We selected tead3b, a member of the evolutionarily-conserved Hippo pathway, known to regulate ovarian functions, due to its remarkably strong and evolutionarily conserved binding affinity for miR-202-5p. Deleting the miR-202-5p binding site in the 3' UTR of tead3b, but not of other Hippo pathway members sav1 and vgll4b, triggered a reduced egg production phenotype. This is one of the few successful examples of de novo functional assignment of a miRNA phenotypic target in vivo in vertebrates.

RESUMEN

Introdução: As desvantagens ligadas ao gênero feminino são visualizadas em diversos aspectos da vida, mediante ao patriarcado. É possível compreender que, no caso de mulheres negras, estas se encontram desfavorecidas frente as estruturas sociais, atravessadas por condicionantes de classe, raça e gênero. Além disso, é visto que, em diversos casos, as cuidadoras mulheres, sobretudo, mulheres negras, não escolhem de forma voluntária este papel dentro da conjuntura familiar. Objetivo: Identificar as implicações do cuidado ao familiar adoecido realizado por mulheres negras cuidadoras considerando suas condições socioculturais. Metodologia: Este trabalho é uma revisão integrativa, cuja busca no banco de dados foi realizada em dezembro de 2020, onde 3 resultados foram encontrados na base de dados Web of Science, 48 na base de dados PubMed e 29 na base de dados LILACS. Depois de ler os resumos dos 80 artigos e aplicar os critérios de exclusão, 7 artigos foram selecionados para leitura completa. Finalmente, 4 artigos foram incluídos para análise. Resultados: Apenas um estudo abordou exclusivamente mulheres, e a maioria eram afro-americanos. Dados indicam que, dentro de uma comunidade quilombola, o cuidado com a saúde é repassado do mais velho para o mais novo, como símbolo de respeito aos saberes ancestrais. Além disso, ficou evidente que cuidadores afro-americanos de pessoas com demência precisam de informações de qualidade sobre cuidados e autocuidado, necessitando de recursos em sua comunidade. Conclusão: É possível notar as desigualdades de acordo com as construções históricas, políticas e culturais causadas, para diferenciar homens e mulheres no cuidado familiar. Havendo uma necessidade de debates que tenham como enfoque a população negra, principalmente as cuidadoras, visando estratégias para reduzir sua sobrecarga para cuidar de familiares em adoecimento.

Introduction: The disadvantages linked to the female gender are viewed in different aspects of life, through patriarchy. It is possible to understand that, in the case of black women, they are disadvantaged in the face of social structures, crossed by class, race and gender conditioning factors. In addition, it is seen that, in several cases, female caregivers, especially black women, do not voluntarily choose this role within the family environment. Objective: To identify the implications of care for a sick family member performed by black women caregivers considering their sociocultural conditions. Methodology: This work is an integrative review, whose search in the database was carried out in December 2020, where 3 results were found in the Web of Science database, 48 in the PubMed database and 29 in the LILACS database. After reading the abstracts of the 80 articles and applying the exclusion criteria, 7 articles were selected for full reading. Finally, 4 articles were included for analysis. Results: Only one study exclusively addressed women, and most were African Americans. Data indicate that, within a quilombola community, health care is passed on from the oldest to the youngest, as a symbol of respect for ancestral knowledge. In addition, it became evident that African-American caregivers of people with dementia need quality information about care and self-care, requiring resources in their community. Conclusion: It is possible to notice the inequalities according to the historical, political and cultural constructions caused, in order to differentiate men and women in family care. There is a need for debates that focus on the black population, especially caregivers, aiming at strategies to reduce their burden to care for sick family members.

RESUMEN

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is a serious global public health concern associated with social vulnerability. In Brazil, the Unified Health System (SUS, Portuguese) provides free diagnosis and treatment for MDR-TB; however, other expenses may still be incurred for patients and their families which, according to the World Health Organization (WHO), can be catastrophic when these costs surpass 20.0% of the annual household income. This study aimed to assess the extent of catastrophic costs related to the diagnostic and therapeutic aspects of MDR-TB among patients receiving care at an outpatient clinic in Rio de Janeiro. METHODS: This prospective study used convenience sampling from July 2019 to June 2021. Data regarding direct and indirect costs were collected using a standardized questionnaire endorsed by the WHO. To analyze any impoverishment occurred from MDR-TB, a threshold established by the Brazilian Institute of Geography and Statistics for 2019 and 2020 of US$ 79,562 and US$ 94,5273, respectively, was applied. Descriptive statistics were used for data analysis, including mean; standard deviation; variation coefficient; median; and maximum, minimum, and interquartile ranges. RESULTS: A total of 65 patients were interviewed. Among the participants, 73.8% experienced catastrophic costs, with indirect costs exerting the most significant impact (median: US$ 3,825.9), in contrast to direct costs (median: US$ 542.7). When comparing the periods before and after diagnosis, the prevalence of poverty increased from 12.0% to 28.0%. CONCLUSIONS: Despite the support from the SUS in Brazil, diagnostic and therapeutic cascades incur additional costs, exacerbating social vulnerability among patients with MDR-TB.

RESUMEN

The vitrification of ovarian follicles is a strategic tool that may contribute to advances in aquaculture and the conservation of many important species. Despite the difficulties inherent to the cryopreservation of oocytes, some successful protocols have been developed for different species, but little is known about the capacity of oocytes to develop after thawing. Therefore, the profiles of the reproductive pathway genes and fatty acid membrane composition during the initial stages of development were analyzed in fresh ovarian follicles and follicles after the vitrification process. There were differences in the expression of the hypothalamic-pituitary-gonad axis genes during the follicular development in the control group as well as in the vitrified group. Similarly, alterations in the composition of fatty acids were observed after vitrification. Despite this, many alterations were observed in the vitrified group; more than half of the stage III ovarian follicles were able to grow and mature in vitro. Therefore, the vitrification of ovarian follicles may impact them at molecular and membrane levels, but it does not compromise their capability for in vitro maturation, which indicates that the technique can be a strategic tool for aquaculture.

RESUMEN

Two triatomine genera (Panstrongylus and Triatoma) have essentially been recorded in Rio Grande do Sul State, Brazil. Panstrongylus megistus should be highlighted since this species is one of the main vectors of Trypanosoma cruzi in Brazil, due to its wide geographical distribution and the high susceptibility to this protozoan. This study aimed to present not only the occurrence and distribution of P. megistus in the Porto Alegre city's metropolitan area (PAMA), Rio Grande do Sul State, Brazil, but also the rates of T. cruzi infection, from 2009 to 2020. The PAMA, which comprises 34 cities and 4.4 million habitants, extends across the transition area in two biomes - Pampa and Mata Atlantica - found in the state. Results showed that P. megistus was recorded in 76.5% of cities (i.e., 26 out of 34), mainly in Porto Alegre city, where the vector was found in 11 out of the 12 years that were monitored. Three hundred and nineteen specimens were captured. Two hundred and sixty-seven specimens (83.7%) were located intradomicile (p < 0.0001), while 52.3% positivity for T. cruzi was found. Thus, P. megistus is important in the PAMA, because it invades and colonizes the households. Moreover, the high rates of T. cruzi infection have drawn attention.

RESUMEN

Triatoma rubrovaria has been captured in some areas of Rio Grande do Sul State (RS), Brazil, as this species can be found in the Pampa biome. Its distribution across this biome should be described in detail to verify the potential of this vector to transmit Trypanosoma cruzi. This study aimed to investigate the occurrence of T. rubrovaria in the Pampa biome and transitional areas of RS. The collected information resulted from the analysis of secondary data provided by the Centro Estadual de Vigilancia em Saude (CEVS - State's Center of Health Surveillance). The following aspects were taken into consideration: the year in which the insect was captured, the city, the number of specimens captured, invasion or domiciliation, the notification in the household, surroundings or both, and T. cruzi infection. The data comprised the period from 2009 to 2020, in 109 cities located in the Pampa biome and 98 located in transitional areas. The Pampa biome exhibited 85% of the occurrences of T. rubrovaria, while 1.2% of specimens were T. cruzi-like positive. Both the first and second biennia concentrated 64.6% of captures. Alegrete city, Cangucu city and Piratini city were the locations in the Pampa where the largest numbers of specimens were found. Regarding the transitional areas, Roque Gonzales city, Santiago city and Santana da Boa Vista city exhibited the largest numbers. Most insects were adults, which were found in households. Even though positivity for T. cruzi-like was low, the species still has epidemiological importance in the region.

RESUMEN

Vulnerable populations, such as migrants and refugees, have an increased risk of tuberculosis disease, especially in the first years after arrival in the host country. The presence of migrants and refugees in Brazil exponentially grew over the period between 2011 and 2020, and approximately 1.3 million migrants from the Global South were estimated to be residing in Brazil, most of whom from Venezuela and Haiti. Tuberculosis control programs for migrants can be divided into pre- and post-migration screening strategies. Pre-migration screening aims to identify cases of tuberculosis infection (TBI) and can be carried out in the country of origin (pre-entry) or in the destination country (at entry). Pre-migration screening can also detect migrants at an increased risk of developing tuberculosis in the future. High-risk migrants are then followed up in post-migration screening. In Brazil, migrants are considered a priority group for the active search for tuberculosis cases. However, there is no recommendation or plan regarding screening for TBI in migrants and refugees. Ensuring prevention, diagnosis, and treatment for TBI and tuberculosis disease in migrant populations is an important aspect of tuberculosis control and elimination. In this review article, we address epidemiological aspects and access to health care for migrants in Brazil. In addition, the migration medical screening for tuberculosis was reviewed.

RESUMEN

Epilepsy is characterized by a predisposition to generate recurrent and spontaneous seizures; it affects millions of people worldwide. Status epilepticus (SE) is a severe type of seizure. In this context, screening potential treatments is very important. In the present study, we evaluated the beneficial effects of rosmarinic acid (RA) in pilocarpine-induced in vitro and in vivo models of epileptiform activity. Using an in vitro model in combined entorhinal cortex-hippocampal from Wistar rats we evaluated the effects of RA (10 µg/mL) on the lactate release and a glucose fluorescent analogue, 2-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)-2-deoxyglucose (2-NDBG), after incubation in high potassium aCSF supplemented or not with pilocarpine. In the in vivo model, SE was induced in male C57BL/6 mice by pilocarpine. At 1, 24, and 48 h after the end of SE mice were treated with RA (30 mg/kg/v.o.). We evaluated the neuromotor impairment by neuroscore tests and protein carbonyl levels in the cerebral cortex. In both in vitro models, RA was able to decrease the stimulated lactate release, while no effect on 2-NBDG uptake was found. RA has beneficial effects in models of epileptiform activity in vivo and in vitro. We found that RA treatment attenuated SE-induced neuromotor impairment at the 48 h timepoint. Moreover, post-SE treatment with RA decreased levels of protein carbonyls in the cerebral cortex of mice when compared to their vehicle-treated counterparts. Importantly, RA was effective in a model of SE which is relevant for the human condition. The present data add to the literature on the biological effects of RA, which could be a good candidate for add-on therapy in epilepsy.

RESUMEN

OBJECTIVES: Evatuate if Bacillus Calmette-Guérin (BCG) vaccine could be used as a tool against SARS-CoV-2 based on the concept of trained immunity. METHODS: A multicenter, double-blinded, randomized clinical trial recruited health care workers (HCWs) in Brazil. The incidence rates of COVID-19, clinical manifestations, absenteeism, and adverse events among HCWs receiving BCG vaccine (Moreau or Moscow strains) or placebo were compared. BCG vaccine-mediated immune response before and after implementing specific vaccines for COVID-19 (CoronaVac or COVISHIELD) was analyzed. Cox proportional hazard and linear mixed effect modeling were used. RESULTS: A total of 264 volunteers were included for analysis (BCG = 134 and placebo = 130). The placebo group presented a COVID-19 cumulative incidence of 0.75% vs 0.52% of BCG. The Moreau strain also presented a higher incidence rate (1.60% × 0.22%). BCG did not show a protective hazard ratio against COVID-19. In addition, the log (immunoglobulin G) level against SARS-CoV-2 presented a higher increase in the BCG group, whether or not participants had COVID-19, but also without statistical significance. CONCLUSION: Our results suggest that BCG has a tendency of protection against SARS-CoV-2 and higher immunoglobulin G levels than placebo. The clinical trial was registered at https://clinicaltrials.gov/ (NCT04659941).

RESUMEN

Triatoma rubrovaria subcomplex consists of T. carcavalloi, T. circummaculata, T. klugi, T. limai, T. oliveirai, T. pintodiasi, T. rubrovaria, T. patagonica and T. guasayana, which can be vectors of Trypanosoma cruzi, the etiologic agent of Chagas disease. In this study, morphological, morphometric, and genetic characters of T. circummaculata, T. pintodiasi, T. carcavalloi, T. klugi, and T. rubrovaria were analyzed in view of the integrative taxonomy and phylogeny of the T. rubrovaria subcomplex. Molecular studies were carried out through the sequencing and analysis of the mitochondrial genes COI and CytB, nuclear genes ITS I, ITS 2, 16S, and 28S from rDNA and rescued a monophyletic group. Furthermore, differential morphological characters were found among the five species in the pronotum, scutellum, stridulatory sulcus, male genitalia, and external female genitalia. Finally, morphometric analyses made it possible to differentiate the five species. Phylogenetic analyzes rescued the relationship of T. pintodiasi with members of the T. rubrovaria subcomplex and demonstrated that this subcomplex is a monophyletic group composed of the species T. carcavalloi, T. circummaculata, T. klugi, T. guasayana, T. limai, T. oliveirai, T. patagonica, T. pintodiasi, and T. rubrovaria. Furthermore, through integrative taxonomy, it was possible to confirm the specific status of the species T. carcavalloi, T. circummaculata, T. pintodiasi, T. klugi, and T. rubrovaria, offering new useful morphological characters for the differentiation and characterization of these potential vectors and distributed in Southern Brazil.

RESUMEN

PURPOSE: To evaluate the prevalence and potential predictors of obstructive sleep apnea (OSA) in a cohort of adults with severe asthma. METHODS: From March 2021 to December 2021, this cross-sectional study enrolled patients with severe asthma receiving biologics, who were consecutively referred for sleep evaluation irrespective of sleep-related symptoms. Clinical and functional data, including three OSA screening instruments (GOAL, STOP-Bang, and NoSAS) were recorded. All participants underwent a portable sleep test (ApneaLink Air™). OSA diagnosis was based on the respiratory disturbance index ≥ 5.0/h and subclassified according to severity thresholds. Data were subjected to logistic regression tests to identify possible predictors for OSA. Discrimination was estimated from the area under the curve (AUC). RESULTS: Overall, 56 outpatients were included (80% females): 54% with any OSA, 13% with moderate-to-severe OSA, and 4% with severe OSA. In the multivariate analysis, no parameter emerged as an independent predictor for OSA: age (p = 0.080), body mass index (p = 0.060), loud snoring (p = 0.130), and hypertension (p = 0.848). No screening instrument was useful to predict any OSA: GOAL (AUC: 0.714; 95% confidence interval (CI): 0.579-0.849), NoSAS (AUC: 0.645; 95% CI: 0.497-0.793), and STOP-Bang (AUC: 0.640; 95% CI: 0.493-0.788). Similarly, no screening tool was also useful for predicting moderate-to-severe OSA or severe OSA. CONCLUSION: Patients with evere asthma receiving biologics exhibit a high prevalence of OSA. However, no clinical, functional, or OSA screening instrument showed acceptable discriminatory ability to predict the presence of OSA in these patients with severe asthma.

RESUMO Populações vulneráveis, como imigrantes e refugiados, apresentam maior risco de tuberculose doença, especialmente nos primeiros anos após a chegada ao país de acolhimento. A presença de imigrantes e refugiados no Brasil cresceu exponencialmente no período entre 2011 e 2020, sendo estimado que aproximadamente 1,3 milhão de imigrantes do Sul Global residiam no Brasil, a maioria proveniente da Venezuela e do Haiti. Os programas de controle da tuberculose para imigrantes podem ser divididos em estratégias de triagem pré- e pós-migração. A triagem pré-migração visa identificar casos de tuberculose infecção (TBI) e pode ser realizada no país de origem (pré-entrada) ou no país de destino (no momento da entrada). A triagem pré-migração também pode detectar imigrantes com maior risco de desenvolver tuberculose no futuro. Os imigrantes de alto risco são então acompanhados na triagem pós-migração. No Brasil, os imigrantes são considerados um grupo prioritário para a busca ativa de casos de tuberculose. No entanto, não há recomendação ou plano sobre triagem para TBI em imigrantes e refugiados. Garantir a prevenção, o diagnóstico e o tratamento da TBI e da tuberculose doença em populações imigrantes é um aspecto importante do controle e eliminação da tuberculose. Neste artigo de revisão, abordamos aspectos epidemiológicos e acesso à saúde para imigrantes no Brasil. Além disso, revisou-se a triagem médica de imigrantes para tuberculose.
