Interspecific association between two primatespecies in an urban park / Associação interespecífica entre duas espécies de primatas em um parque urbano

As with Amazonian primates, mixed associations between species in the Atlantic Forest are also influenced by ecological factors. However, Atlantic Forest primates may face additional challenges, such as isolation pressures and fragmentation of forest habitats, which may increase the frequency of these arrangements. The main of this work is to report a sympatry with possible interaction between individuals of two species of primates of the Pitheciidae and Callitrichidae families: Callicebus nigrifrons (Spix 1823) and Callithrix aurita (É. Geoffroy Saint-Hilaire 1812) in an urban park in the south of the state of Minas Gerais. Individuals were observed interacting during foraging and displacement. The association of individuals of the two species can be explained by the low quality of the forest fragment, as it can increases the chances of obtaining food resources and configures a dilution strategy against predator attacks.

Assim como ocorre com os primatas amazônicos, as associações mistas entre espécies na Mata Atlântica também são influenciadas por fatores ecológicos. No entanto, os primatas da Mata Atlântica podem enfrentar desafios adicionais, como pressões de isolamento e fragmentação de habitats florestais, que podem aumentar a frequência desses arranjos. O objetivo deste trabalho é apresentar um relato de simpatia com possível interação entre indivíduos de duas espécies de primatas das famílias Pitheciidae e Callitrichidae: Callicebus nigrifrons (Spix 1823) e Callithrix Resumo aurita (É. Geoffroy Saint-Hilaire 1812) em um parque urbano no sul do estado de Minas Gerais. Foram observados indivíduos interagindo durante o forrageio e deslocamento. A associação de indivíduos das duas espécies pode ser explicada devido à baixa qualidade do fragmento florestal, pois pode aumentar as chances de obter recursos alimentares e configura uma estratégia de diluição de contra-ataques de predadores.

High volume online hemodiafiltration: a global perspective and the Brazilian experience / Hemodiafiltração on-line de alto volume: uma perspectiva global e a experiência brasileira

ABSTRACT Online hemodiafiltration (HDF) is a rapidly growing dialysis modality worldwide. In Brazil, the number of patients with private health insurance undergoing HDF has exceeded the number of patients on peritoneal dialysis. The achievement of a high convection volume was associated with better clinical imprand patient - reported outcomes confirming the benefits of HDF. The HDFit trial provided relevant practical information on the implementation of online HDF in dialysis centers in Brazil. This article aims to disseminate technical information to improve the quality and safety of this new dialysis modality.

Dados nacionais do estudo HDFit forneceram informações práticas relevantes sobre a implementação da HDF on-line em clínicas de diálise no Brasil. O objetivo desta publicação é a disseminação de informações técnicas que possam auxiliar na utilização, com qualidade e segurança, dessa nova modalidade dialítica.

Do oral antiseptics used in the dental routine have anti-viral efficacy? a systematic review of in vitro studies / Os antissépticos orais utilizados na rotina odontológica têm eficácia anti-viral? Uma revisão sistemática de estudos in vitro / ¿Los antisépticos orales utilizados en la rutina odontológica tienen eficacia antiviral? Una revisión sistemática de estudios in vitro

Introduction: Mouthwashes play an important role in the dental clinic, but their role on viruses requires investigation. Objective:to review in vitro studies to identify the effect of different mouthwashes on the main viruses associated with routine dental care. Methodology:The following databases were searched in September 2023: PubMed, Embase, Scopus and Web of Science databases; the Cochrane Library and the Virtual Health Library (VHL); and grey literature. In vitro studies that used mouthwashes to reduce the viral load were selected. The PICOS strategy was considered to define eligibility criteria: the Population (viruses involved in the etiology of oral infection), the Intervention (oral antiseptics), the appropriate comparator (positive and negative controls), the Outcomes of interest (reduction of viral load) and the Study design (in vitro studies). Results:Considering the eligibility criteria, 19 articles were included in this review. The efficacy of povidone-iodine (PVP-I), chlorhexidine, Listerine®, essential oils, and cetylpyridinium chloride (CPC) rinses were investigated. PVP-I (0.23%) had its effects mainly associated with coronaviruses SARS(Severe Acute Respiratory Syndrome),demonstrating a significant reduction in viral load after 15 seconds of exposure. Chlorhexidine (0.05%; 0.1% and 0.5%) was ineffective against adenovirus, poliovirus, and rhinovirus respiratory viruses. Listerine® demonstrated superior efficacy against HSV-1 and 2 viruses and influenza A, and cetylpyridine chloride also demonstrated virucidal activity against influenza A. Conclusions:The type, concentration, and time of exposure to antiseptics varied between studies. PVP-I and chlorhexidine digluconate were the most studied substances, butin general, PVP-I was more effective in reducing viral titers, especially concerning coronaviruses. Other antiseptics such as CPC, H2O2 and Listerine® have also shown significant reduction in viral load, but this is a limited number of studies (AU).

Pediatric nephrologist-intensivist interaction in acute kidney injury / Interação nefro-intensivista pediátrica na lesão renal aguda

ABSTRACT Introduction: Acute Kidney Injury (AKI) in the Intensive Care Unit (ICU) have concepts of diagnosis and management have water balance as their main point of evaluation. In our ICU, from 2004 to 2012, the nephrologist's participation was on demand only; and as of 2013 their participation became continuous in meetings to case discussion. The aim of this study was to establish how an intense nephrologist/intensivist interaction influenced the frequency of dialysis indication, fluid balance and pRIFLE classification during these two observation periods. Methods: Retrospective study, longitudinal evaluation of all children with AKI undergoing dialysis (2004 to 2016). Parameters studied: frequency of indication, duration and volume of infusion in the 24 hours preceding dialysis; diuresis and water balance every 8 hours. Non-parametric statistics, p ≤ 0.05. Results: 53 patients (47 before and 6 after 2013). There were no significant differences in the number of hospitalizations or cardiac surgeries between the periods. After 2013, there was a significant decrease in the number of indications for dialysis/year (5.85 vs. 1.5; p = 0.000); infusion volume (p = 0.02), increase in the duration of dialysis (p = 0.002) and improvement in the discrimination of the pRIFLE diuresis component in the AKI development. Conclusion: Integration between the ICU and pediatric nephrology teams in the routine discussion of cases, critically approaching water balance, was decisive to improve the management of AKI in the ICU.

RESUMO Introdução: Os conceitos sobre diagnóstico e conduta da Lesão Renal Aguda (LRA) na Unidade de Terapia Intensiva (UTI) tem como ponto primordial a avaliação do balanço hídrico. Em nossa UTI, de 2004 a 2012, a participação do nefrologista era sob demanda. A partir de 2013, a participação passou a ser contínua em reunião de discussão de casos. O objetivo deste estudo foi determinar como a maior interação nefrologista/intensivista influenciou a frequência de indicação de diálise, no balanço hídrico e na classificação pRIFLE durante esses dois períodos de observação. Método: Estudo retrospectivo, avaliação longitudinal de todas as crianças com LRA em diálise (2004 a 2016). Parâmetros estudados: frequência de indicação, tempo de duração e volume de infusão nas 24 horas precedendo a diálise; diurese e balanço hídrico a cada 8 horas. Estatística não paramétrica, p ≤ 0,05. Resultado: 53 pacientes (47 antes e 6 após 2013). Sem diferença significativa no número de internações e nem de cirurgias cardíacas entre os períodos. Após 2013, houve diminuição significativa no número de indicação de diálise/ano (5,85 vs. 1,5; p = 0,000); no volume de infusão (p = 0,02), aumento do tempo de duração da diálise (p = 0,002) e melhora da discriminação do componente diurese do pRIFLE na indicação de LRA. Conclusão: Integração entre equipes de UTI e nefrologia pediátrica na discussão rotineira de casos, abordando criticamente o balanço hídrico, foi determinante para a melhora na conduta da LRA na UTI.

Malformações arteriovenosas pulmonares na síndrome de Rendu-Osler-Weber / Pulmonary arteriovenous malformations in Rendu-Osler-Weber syndrome

Resumo A síndrome de Rendu-Osler-Weber, também conhecida como telangiectasia hemorrágica hereditária, é uma doença hereditária autossômica dominante. Ela é caracterizada pela presença de múltiplas malformações arteriovenosas e telangiectasias. Este artigo relata dois casos de pacientes com síndrome de Rendu-Osler-Weber que apresentaram malformações arteriovenosas pulmonares e foram submetidos a tratamento endovascular com sucesso. Uma breve revisão da literatura mostra que até 50% dos pacientes com a síndrome têm malformações arteriovenosas pulmonares e geralmente há um histórico familiar positivo nesses pacientes. Em 30% dos casos, elas são múltiplas e estão associadas a complicações mais graves da doença. A maioria dos pacientes é assintomática, mesmo na presença de malformações arteriovenosas com shunt direito-esquerdo. Quando esses shunts excedem 25% do volume total de sangue, podem surgir dispneia, cianose, baqueteamento digital e sopros extracardíacos. O tratamento endovascular oferece segurança e controle das complicações da telangiectasia hemorrágica hereditária, sendo atualmente o tratamento de escolha para essas lesões.

Abstract Rendu-Osler-Weber syndrome, also known as hereditary hemorrhagic telangiectasia, is an autosomal dominant hereditary disorder. It is characterized by presence of multiple arteriovenous malformations (AVMs) and telangiectasias. This article reports two cases of patients with Rendu-Osler-Weber syndrome who had pulmonary AVMs and underwent successful endovascular treatment. A brief review of the literature shows that up to 50% of patients with the syndrome have pulmonary AVMs and there is usually a positive family history in these patients. These pulmonary AVMs are multiple in 30% of cases and are associated with the most severe disease complications. Most patients are asymptomatic, even in the presence of AVMs with right-left shunts. When these shunts exceed 25% of the total blood volume, dyspnea, cyanosis, digital clubbing, and extracardiac murmurs may occur. Endovascular treatment is safe and offers control of complications from hereditary hemorrhagic telangiectasia and is currently the treatment of choice for these lesions.

Fatores de risco psicossociais relacionados ao trabalho: uma análise contemporânea / Work-related psychosocial risk factors: a contemporary analysis

Resumo Introdução: nos debates sobre a proteção e a promoção da saúde nos contextos laborais, o tema dos fatores psicossociais relacionados ao trabalho (FPRT) tem se destacado. Objetivo: demonstrar que a ausência da tematização do antagonismo e do conflito estrutural entre capital e trabalho, bem como a captura da temática pela lógica gerencialista neoliberal, produz o empobrecimento do debate e o enfraquecimento de iniciativas voltadas para a transformação do contexto laboral. Método: a reflexão é realizada a partir de revisão da literatura, tendo como referencial o materialismo histórico. Resultados: as formulações de políticas, instrumentos e medidas destinadas à proteção da saúde dos trabalhadores, gestadas nos marcos ideológicos do regime de acumulação capitalista e da governamentalidade neoliberal, convertem-se em compreensões e intervenções que, longe de transformarem as situações concretas de trabalho, mascaram o papel exercido pelo trabalho em relação à saúde dos trabalhadores, consagram as ações voltadas aos indivíduos, arrefecem as lutas sociais e ampliam as pressões sobre os trabalhadores. Conclusão: o enfrentamento dos riscos psicossociais não deve se limitar à mitigação desses riscos, mas sim encontrar seus propósitos e seus fundamentos em um horizonte teórico-prático que descortine a necessidade de superação da própria economia capitalista.

Abstract Introduction: work-related psychosocial factors have stood out in debates concerning health protection and promotion in occupational contexts. Objective: this essay demonstrates how the lack of thematic exploration regarding the antagonism and structural conflict between capital and labor, as well as its co-optation by neoliberal managerial logic, impoverishes the debate and weakens initiatives aimed at transforming the work environment. Method: a literature review was conducted using historical materialism as a theoretical framework. Results: policies, instruments, and measures formulated to protect workers' health developed under the ideological framework of capitalist accumulation and neoliberal governmentality become understandings and interventions that, far from transforming actual work situations, mask the role played by work in occupational health. They consecrate actions focused on individuals, dampen social struggles, and increase pressure on workers. Conclusion: addressing psychosocial risks should not be limited to mitigating them; rather, it should find its purposes and foundations in a theoretical-practical horizon that unveils the need to overcome the capitalist economy itself.

Acne treatment challenges - Recommendations of Latin American expert consensus

Abstract Background Acne is a chronic inflammatory disorder of the pilosebaceous unit that is associated with a negative impact on quality of life, causing anxiety, depression, and poor self-esteem. The treatment of acne is not simple and presents some new challenges. This article addresses important issues faced by dermatologists on their daily, some of them specific for Latin America. Objective To discuss daily practice recommendations when managing acne patients. Methods A literature review was conducted by a group of eight experts with extensive experience in the field of acne. The results of the data review were presented at an initial kick-off meeting to align the consensus topics. Two e-surveys using the Delphi methodology and an interim group webinar meeting were held. Results The expert panel reached a consensus on all proposed key statements, providing scientific support to help dermatologists and healthcare providers make acne management decisions on topics that can be challenging in the everyday practice of dermatology, such as the characteristics of Generation Z or the importance of the maintenance phase of adult acne treatment. Conclusion This article provides current recommendations for managing acne patients. The high level of agreement achieved based on the latest evidence supports the best acne therapeutic choices in both established topics and new important issues that have emerged in recent years, such as the impact of social media, Generation Z characteristics, and transgender male patient specifics.

Feasibility, safety, and adherence of a remote physical and cognitive exercise protocol for older women / Viabilidade, segurança e aderência de um protocolo remoto de exercícios físicos e cognitivos para mulheres idosas

Abstract Background Population aging and the consequences of social distancing after the COVID-19 pandemic make it relevant to investigate the feasibility of remote interventions and their potential effects on averting functional decline. Objective (1) To investigate the feasibility, safety, and adherence of a remote protocol involving physical and cognitive exercises for older women with normal cognition; (2) to examine its effects on cognitive and well-being variables. Methods Twenty-nine women (age ≥ 60 years old) were randomized into experimental group (EG; n= 15) and control group (CG; n= 14). The EG performed a 40-minute session of cognitive and physical exercises, and CG performed a 20-minute stretching session. Both groups performed 20 sessions via videoconference and 20 on YouTube twice a week. The Mini-Mental State Examination, Verbal Fluency Test, Digit Span (direct an inverse order), Geriatric Depression Scale (GDS), and Well-being Index (WHO-5) were applied in pre- and post-interventions by phone. Results Overall adherence was 82.25% in EG and 74.29% in CG. The occurrence of adverse events (mild muscle pain) was 33.3% in EG and 21.4% in CG. The EG improved verbal fluency and attention (p ≤ 0.05); both groups had improved depressive symptoms. Conclusion The present study met the pre-established criteria for feasibility, safety, and adherence to the remote exercise protocol among older women. The results suggest that a combined protocol has more significant potential to improve cognitive function. Both interventions were beneficial in improving the subjective perception of well-being.

Resumo Antecedentes O envelhecimento populacional e as consequências do isolamento social após a pandemia de COVID-19 tornaram relevante investigar a viabilidade, segurança e aderência de intervenções remotas e potenciais efeitos para prevenir declínios funcionais. Objetivo (1) Investigar a viabilidade, segurança e aderência de um protocolo remoto de exercícios físicos e cognitivos; (2) investigar os possíveis efeitos sobre variáveis de cognição e de bem-estar. Métodos Vinte e nove mulheres foram randomicamente divididas em grupo experimental (GE; n= 15) e grupo controle (GC; n= 14). O GE realizou sessões de 40 minutos de exercícios físicos e cognitivos e o GC, 20 minutos de alongamentos. Totalizaram 20 sessões por videoconferência e 20 pelo YouTube, duas vezes por semana. O Teste de Fluência Verbal, o Teste de Dígitos (ordem direta e inversa), a Escala de Depressão Geriátrica (GDS) e o Índice de Bem-Estar (WHO-5) foram aplicados no pré e pós-intervenção, por telefone e formulário digital. Resultados A aderência geral média foi de 82,25% no GE e 74,29% no GC. A ocorrência de eventos adversos (dores musculares leves) foi de 33,3% no GE e 21,4% no GC. O GE teve melhora em fluência verbal e atenção (p ≤ 0.05) e ambos os grupos tiveram melhora significativa nos sintomas depressivos. Conclusão O presente estudo atendeu aos critérios preestabelecidos para a viabilidade, segurança e aderência do programa oferecido entre idosas. Os resultados sugerem que o protocolo combinado tenha maior potencial de aprimorar funções cognitivas. Ambas as intervenções foram benéficas para a percepção subjetiva de bem-estar.

Comparative in vitro analysis of the antifungal activity of different calcium silicate-based endodontic sealers

Aim: This study aimed to perform an in vitro comparative analysis of the antifungal activity of different calcium silicate-based endodontic sealers against three fungal species. Methods: The antifungal properties of three calcium silicate-based sealers were tested: Bio-C Sealer, Cambiar a Sealer Plus BC, and MTA-Fillapex. Two commonly used sealers were used as controls: AH Plus and Endomethasone. An agar diffusion test was performed to analyze the antifungal activity of the sealers against Candida albicans, Candida glabrata, Candida tropicalis, and a mixed microbial culture medium. The results were analyzed using ANOVA (p <0.05). Results: Endomethasone exhibited the highest inhibition against all strains examined, maintaining a consistent level of inhibition throughout 7 days. MTA-Fillapex demonstrated the best performance among the calcium silicate-based sealers for the three fungal species (p < 0.05), maintaining stable values over the 7 days, surpassing that of Endomethasone. Nevertheless, MTA-Fillapex only exhibited antimicrobial effect against the mixed culture for the first 24 hours, and no antimicrobial activity was observed at 48 hours, being surpassed by all tested sealers (p < 0.05). Conclusion: Of all silicate-based sealers tested, only MTA-Fillapex exhibited promising antifungal activity. Nevertheless, care must be taken when extrapolating these results, as MTA-Fillapex exhibited poor antimicrobial activity when tested in mixed microbial cultures

Cytotoxic effects of crotoxin from Crotalus durissus terrificus snake in canine mammary tumor cell lines

Background: Mammary gland tumors are the most prevalent neoplasm in intact female dogs, and they are good natural models to study comparative oncology. Most canine mammary malignancies, as in women, are commonly refractory to conventional therapies and demand continuous new therapeutic approaches. Crotalus durissus terrificus, also called rattlesnake, has more than 60 different proteins in its venom with multiple pharmaceutical uses, such as antitumor, antiviral, and antimicrobial action. Crotoxin, a potent β-neurotoxin formed by the junction of two subunits, a basic subunit (CB-PLA2) and an acidic subunit (crotapotin), has already been reported to have anticancer properties in different types of cancers. Methods: In this work, we describe the cytotoxic potential of crotoxin and its subunits compared to doxorubicin (drug of choice) in two canine mammary carcinoma cell lines. Results: Crotoxin, CB-PLA2, crotalic venom, and doxorubicin decreased cell viability and the ability to migrate in a dose-dependent manner, and crotapotin did not present an antitumoral effect. For all compounds, the predominant cell death mechanism was apoptosis. In addition, crotoxin did not show toxicity in normal canine mammary gland cells. Conclusion: Therefore, this work showed that crotoxin and CB-PLA2 had cytotoxic activity, migration inhibition, and pro-apoptotic potential in canine mammary gland carcinoma cell lines, making their possible use in cancer research.

O lado obscuro da internet: uma revisão de literatura sobre o comportamento antissocial online / The internet's dark side: a literature review on antissocial online behaviour / El lado oscuro de internet: una revisión de la literatura sobre el comportamiento antisocial online

O objetivo do estudo foi realizar uma revisão sistemática da literatura acerca do comportamento antissocial online e, também, categorizar esses comportamentos e observar aspectos psicossociais relacionados. Para tanto, foi utilizada uma síntese qualitativa, incluindo estudos quantitativos publicados entre 2016-2020 nas bases de dados Scopus, PsycInfo, Pepsic e Scielo. Vinte e cinco estudos se adequaram às análises. Os resultados demonstraram a existência de quatro categorias de comportamento antissocial online: cyberbullying, trollagem, comportamento antissocial sexual, e cyberstalking. A tétrade sombria (narcisismo, psicopatia, Maquiavelismo e sadismo) mostrou-se o preditor mais consistente dessas categorias nos estudos. O estudo alcançou os objetivos propostos, preenchendo duas lacunas: a inexistência de categorização do comportamento antissocial online e a escassez de estudos brasileiros sobre o tema

The study aimed to conduct a systematic literature review on antisocial online behavior. The objective was also to categorize these behaviors and observe related psychosocial aspects. To this end, a qualitative synthesis was used, including quantitative studies published between 2016-2020 in the Scopus, PsycInfo, Pepsic, and Scielo databases. 25 studies fitted the analyzes. The results demonstrated the existence of four antisocial online behavior categories: cyberbullying, trolling, sexual antisocial behavior, and cyberstalking. The dark tetrad (narcissism, sychopathy, Machiavellianism, and sadism) was the most consistent predictor of these categories among studies. The research fulfilled the proposed purposes, filling two literature gaps: The lack of categorization of antisocial online behavior; and the scarcity of Brazilian studies on the topic

El objetivo del estudio fue realizar una revisión sistemática de la literatura sobre el comportamiento antisocial online. El objetivo también fue categorizar estos comportamientos y observar aspectos psicosociales relacionados. Para ello, se utilizó una síntesis cualitativa, incluyendo estudios cuantitativos publicados entre 2016-2020 en las bases de datos Scopus, PsycInfo, Pepsic y Scielo. 25 estudios se ajustan a los análisis. Los resultados demostraron la existencia de cuatro categorías de comportamiento antisocial en línea: cyberbullying, trolling, comportamiento sexual antisocial y cyberstalking. La tétrada oscura (narcisismo, psicopatía, maquiavelismo y sadismo) fue el predictor más consistente de estas categorías entre los estudios. El estudio cumplió con los objetivos propuestos, llenando dos vacíos: La falta de categorización de la conducta antisocial en línea; y la escasez de estudios brasileños sobre el tema

Health-Related quality of life by 31-item Cervantes scale in breast cancer survivors undergoing adjuvant endocrine therapy

ABSTRACT Introduction Instruments to manage adverse effects of endocrine therapy with Aromatase inhibitors (AI) may improve adherence and persistence to treatment and Health-Related Quality of Life (HRQL). The 31-item Cervantes Scale (CS-31) is an HRQL questionnaire with particularities of the perimenopausal and postmenopausal period that could be an appropriate instrument to assess HRQL in Breast Cancer (BC) survivors. Objective This study aimed to perform additional validation of the CS-31 for BC survivors undergoing adjuvant endocrine therapy. Methods This prospective study was performed at three time points named T0, T1, and T2: initial, intermediate, and final follow-up period, respectively, totaling 24 months of follow-up. At each time point, the participants completed the CS-31, Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), and Hospital Anxiety and Depression Scale (HADS). The internal consistency, construct validity, responsiveness analyses, and known-group validity of CS-31 were evaluated. Results This study included 89 postmenopausal women diagnosed with hormone receptor-positive early BC in adjuvant endocrine therapy with AI. The internal consistency was good (Cronbach's alpha = 0.89). Construct validity received a positive rating, with 100% of results consistent with prior hypotheses. A prospective improvement in HRQL was identified for the CS-31 Global Score and FACIT-F Total Score and for most of their domains. Furthermore, women with anxiety and depression by HADS presented worse HRQL by CS-31. Conclusion The authors identified that the CS-31 seems to be appropriate for use in oncology medical routine and may help to monitor adverse effects and HRQL of BC survivors during adjuvant endocrine therapy.

Benign cervical schwannoma with tracheal invasion

ABSTRACT Schwannomas commonly develop in the cervical region, 25% - 45% of cases are diagnosed in this anatomical region. Tracheal neurogenic tumors are exceedingly rare and can be misdiagnosed as invasive thyroid carcinomas or other infiltrating malignancies when present at the level of the thyroid gland. Here, we present a case of synchronous benign cervical schwannoma with tracheal invasion and papillary thyroid carcinoma in a patient who was initially hospitalized for COVID-19. The patient presented with dyspnea that was later found to be caused by tracheal extension of a cervical tumor. Surgical excision was performed, and the surgical team proceeded with segmental tracheal resection, removal of the cervical mass, and total thyroidectomy. The specimen was sent for pathological analysis, which revealed synchronous findings of a benign cervical schwannoma with tracheal invasion and papillary thyroid carcinoma. The literature on this subject, together with the present case report, suggests that neurogenic tumors should be included in the differential diagnosis of obstructing tracheal cervical masses. Surgical excision is the first-line of treatment for benign cervical schwannomas.

Detection of arboviruses in Aedes aegypti through transovarian analysis: A study in Goiânia, Goiás

Abstract Background: Arboviral diseases are a group of infectious diseases caused by viruses transmitted by arthropods, mainly mosquitoes. These diseases, such as those caused by the dengue (DENV), Zika (ZIKV), chikungunya (CHIKV), and yellow fever (YFV) viruses, have a significant impact worldwide. In this context, entomological surveillance plays a crucial role in the control and prevention of arboviruses by providing essential information on the presence, distribution, and activity of vector mosquitoes. Based on entomological surveillance, transovarian transmission provides information regarding the maintenance and dissemination of arboviruses. The objective of this study was to detect these arboviruses in Goiânia, Goiás, and analyze the occurrence of transovarian transmission. Methods: Aedes aegypti eggs were collected from different regions of Goiânia and cultivated under controlled laboratory conditions until the emergence of adult mosquitoes. Adult females were grouped into pools containing their heads and thoraxes. These pools were subsequently evaluated using reverse-transcription quantitative polymerase chain reaction (RT-qPCR) assay. Results: A total of 157 pools (N=1570) were analyzed, with two pools testing positive for CHIKV and one pool testing positive for ZIKV, indicating that the offspring resulting from transovarian transmission are potentially infectious. Conclusions: In summary, the demonstration of the vertical transmission mechanisms of CHIKV and ZIKV in A. aegypti serves as an alert to health authorities, as these diseases are still underreported, and their primary urban vector has likely acquired this capacity, contributing to the dissemination of these infections.

Contamination of equipment and surfaces in the operating room anesthesia workspace: a cross-sectional study

ABSTRACT BACKGROUND: Contamination of the breathing circuit and medication preparation surface of an anesthesia machine can increase the risk of cross-infection. OBJECTIVE: To evaluate the contamination of the anesthetic medication preparation surface, respiratory circuits, and devices used in general anesthesia with assisted mechanical ventilation. DESIGN AND SETTING: Cross-sectional, quantitative study conducted at the surgical center of a philanthropic hospital, of medium complexity located in the municipality of Três Lagoas, in the eastern region of the State of Mato Grosso do Sul. METHODS: Eighty-two microbiological samples were collected from the breathing circuits. After repeating the samples in different culture media, 328 analyses were performed. RESULTS: A higher occurrence of E. coli, Enterobacter spp., Pseudomonas spp., Staphylococcus aureus, and Streptococcus pneumoniae (P < 0.001) were observed. Variations were observed depending on the culture medium and sample collection site. CONCLUSION: The study findings underscore the inadequate disinfection of the inspiratory and expiratory branches, highlighting the importance of stringent cleaning and disinfection of high-touch surfaces.

Validation of the Brazilian version of the Short Inventory of Grazing (SIG)

Abstract Objective Grazing is a disturbed eating pattern that has been associated with eating disorders and obesity. One of the new measures to investigate this eating behavior is the Short Inventory of Grazing (SIG), a two-item questionnaire that assesses grazing in general and grazing associated with the feeling of loss of control over eating (LOC grazing). However, the psychometric properties of the SIG have not been assessed in the Brazilian population. The present study aimed to cross-culturally adapt and validate a Brazilian version of the SIG. Methods The SIG was adapted to the Brazilian context following international guidelines. Then, 90 undergraduate students completed an online survey including questions from the SIG, the Binge Eating Scale (BES), the Patient Health Questionnaire-9 (PHQ9), the Generalized Anxiety Disorder-7 (GAD7), and a question related to self-reported health status. The internal consistency, test-retest reliability, and convergent validity of the questionnaire were assessed. Results The prevalence rates of at least one weekly episode of grazing in general and LOC grazing were 71.1 and 54.5%, respectively. The internal consistence of the SIG was acceptable (0.81). In addition, SIG scores on both items were positively and significantly associated with BES, GAD7, and PHQ9 scores, and with poorer self-rated health. However, SIG test and retest scores differed significantly. Conclusion Overall, the Brazilian version of the SIG demonstrated adequate psychometric properties. The instrument had adequate internal consistency, with both items exhibiting good convergent validity with related measures.

Vancomycin-associated hemorrhagic occlusive retinal vasculitis masquerading as central retinal vein occlusion / Vasculite hemorrágica oclusiva da retina associada à vancomicina (HORV) mascarada como oclusão da veia central da retina

ABSTRACT A 69-year-old female was referred with sudden unilateral painless decreased vision that began 2 days after uncomplicated cataract surgery in the left eye. Visual acuity was hand motion and biomicroscopy showed a mild anterior chamber reaction, no hypopyon, and an intraocular lens that had been placed within the capsular bag. A dilated fundus examination revealed optic disk edema, widespread deep and superficial intraretinal hemorrhages, retinal ischemia, and macular edema. A cardiological evaluation was normal and thrombophilia tests were negative. After surgery, prophylactic vancomycin (1mg/0.1ml) had been injected intracamerally. The patient was diagnosed with hemorrhagic occlusive retinal vasculitis likely secondary to vancomycin hypersensitivity. Recognition of this entity is important to ensure early treatment and the use of intracameral vancomycin in the fellow eye should be avoided after cataract surgery.

RESUMO Esse caso se refere a uma paciente de 69 anos, sexo feminino, com relato de baixa acuidade visual súbita e indolor no olho esquerdo, de início 2 dias após cirurgia de catarata sem complicações. A acuidade visual era de movimento de mãos e a biomicroscopia mostrou reação de câmara anterior moderada, sem hipópio, e lente intraocular posicionada dentro do saco capsular. A fundoscopia evidenciou edema de disco óptico, hemorragias difusas intrarretinianas superficiais e profundas, isquemia retiniana e edema macular. A avaliação cardiológica foi normal e os testes para trombofilia foram negativos. Ao final da cirurgia foi injetado antibioticoprofilaxia com vancomicina (1mg/0,1ml) na câmara anterior. A paciente foi diagnosticada com vasculite hemorrágica oclusiva da retina secundária à hipersensibilidade a vancomicina. O reconhecimento dessa entidade é importante para o tratamento precoce e para evitar o uso de vancomicina intracameral em caso de cirurgia de catarata no olho contralateral.

Pediatricians' focus of sight at pain assessment during a neonatal heel puncture / Foco do olhar do pediatra na avaliação da dor neonatal durante uma punção de calcanhar

ABSTRACT Objective: To evaluate the focus of pediatricians' gaze during the heel prick of neonates. Methods: Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians' pain perception: absent/mild (score: 0-5) and moderate/intense (score: 6-10). Results: 24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5-8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain. Conclusions: At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face.

RESUMO Objetivo: Avaliar o foco do olhar do pediatra durante a punção do calcanhar de neonatos. Métodos: Estudo prospectivo no qual pediatras, utilizando óculos de rastreamento visual, avaliaram a dor neonatal antes/depois de uma punção de calcanhar. Os pediatras pontuaram a dor de acordo com a sua percepção por meio de uma escala analógica verbal (0=sem dor; 10=dor máxima). Os desfechos analisados foram o número e o tempo das fixações visuais na face superior, face inferior e mãos, em dois períodos de 10 segundos, antes (PRÉ) e depois da punção (PÓS). Os resultados foram comparados entre os períodos e segundo a percepção da dor do pediatra: ausente/leve (escore: 0-5) e moderada/grave (escore: 6-10). Resultados: Vinte e quatro pediatras (31 anos, 92% sexo feminino) avaliaram 24 neonatos. A mediana do escore atribuído à dor do recém-nascido durante a punção do calcanhar foi 7,0 (intervalo interquartil: 5-8). Comparado ao período PRÉ, no período PÓS, o maior número de pediatras fixou o olhar na face inferior (63 vs. 92%; p=0,036) e o número de fixações visuais foi maior na face inferior (2,0 vs. 5,0; p=0,018). Não houve diferença no número e no tempo das fixações visuais de acordo com a intensidade da dor. Conclusões: À beira do leito, os pediatras mudam seu foco de atenção visual na face do recém-nascido após um procedimento doloroso, focando o olhar principalmente na parte inferior da face.

Physiological and psychoaffective responses of adults trained in acute hiit protocols / Respuestas fisiológicas y psicoafectivas de adultos entrenados en protocolos agudos de hiit / Respostas fisiológicas e psicoafetivas de adultos treinados em protocolos agudos de hiit

ABSTRACT High Intensity Interval Training (HIIT) promotes similar adaptations and in some cases, superior to continuous aerobic training of moderate intensity, even when performed at all-out intensities. In this condition, it tends to have the greatest physiological disturbance and accumulation of metabolites compared to submaximal intensities, being one of the main factors associated with the negative response of pleasure in training. Objective: To verify the relationship between physiological and psychophysiological responses in order to repeat the training of two HIIT protocols of mesm volume load and different periods of work in trained adults of both sexes. Methods: In a randomized experiment, the sample consisted of 9 individuals aged 28±5 years, body mass 69.6±14.2 kg, height 169±0.1cm, BMI 24.1±2.3 kg/m2 and body fat percentage 20.2±7.9% practitioners of structured aerobic physical exercises for at least six months. Two different HIIT protocols were performed on an exercise bike, being (I) protocol 1:0.5, with prescribed intensity (80-90% of MAX HR), (II) protocol 1:2 with prescribed intensity (all-out) with total duration of effort of 20 minutes and interval of at least 48 hours between each session. Heart rate (HR), systemic blood pressure (SBP), subjective perception of exertion (SPE), visual analog scale (VAS), affective response (AR), fun (PACES) and intention to repeat the session were analyzed. The statistical analysis used was ANOVA with Tukey's post-hoc (p<0.05). Results: The analyses of HR, SBP, VAS, PACES and SPE showed no significant difference between the training protocols. The affective response (AR and intention to repeat) showed a decline in the protocol 1:0.5, but without significance (p>0.05). Conclusion: The data allow us to conclude that the 1:2 protocol caused greater physiological disturbances during exertion and presented greater positive affective response and intention to repeat the exercise session, variables that may contribute to adherence to regular physical exercise.

RESUMEN El entrenamiento de intervalos de alta intensidad (HIIT) promueve adaptaciones similares y, en algunos casos, superiores al entrenamiento aeróbico continuo de intensidad moderada. En esta condición, tiende a tener una mayor alteración fisiológica y acumulación de metabolitos en comparación con las intensidades submáximas, siendo uno de los principales factores asociados con la respuesta negativa del placer en el entrenamiento. Objetivo: Verificar la relación entre las respuestas fisiológicas y psicofisiológicas para repetir el entrenamiento de dos protocolos HIIT de carga del mismo volumen y diferentes períodos de trabajo en adultos entrenados de ambos sexos. Métodos: En un experimento aleatorizado, la muestra estuvo constituida por 9 individuos de 28±5 años, masa corporal 69,6±14,2 kg, altura 169±0,1cm, IMC 24,1±2,3 kg/m2 y porcentaje de grasa corporal 20,2±7,9% practicantes de ejercicios físicos aeróbicos estructurados durante al menos seis meses. Se realizaron dos protocolos HIIT diferentes en bicicleta estática, siendo protocolo 1: 0,5, con intensidad prescrita (80-90% de la FC MÁXIMA), protocolo 1: 2 con intensidad prescrita (total) con duración total del esfuerzo de 20 minutos e intervalo de al menos 48 horas entre cada sesión. Se analizaron la frecuencia cardíaca (FC), presión arterial sistémica (PAS), percepción subjetiva de esfuerzo (PSE), escala analógica visual (EVA), respuesta afectiva (FS), diversión (PACES) e intención de repetir la sesión. El análisis estadístico utilizado fue ANOVA con post-hoc de Tukey (p<0,05). Resultados: Los análisis de HR, PAS, EVA, PACES y PSE no mostraron diferencias significativas entre los protocolos de entrenamiento. La respuesta afectiva (FS e intención de repetir) mostró una disminución en el protocolo 1:0,5, pero sin significancia (p>0,05). Conclusión: Los datos permiten concluir que el protocolo 1:2 causó mayores alteraciones fisiológicas durante el esfuerzo y presentó mayor respuesta afectiva positiva e intención de repetir la sesión de ejercicio, variables que pueden contribuir para la adhesión al ejercicio físico.

RESUMO O Treinamento Intervalado de Alta Intensidade (HIIT) promove adaptações semelhantes e em alguns casos, superiores ao treinamento aeróbico contínuo de intensidade moderada, mesmo quando executado em intensidades all out. Nesta condição, tende a maior perturbação fisiológica e acúmulo de metabólitos comparado a intensidades submáximas, sendo um dos principais fatores associados a resposta negativa de prazer no treinamento. Objetivo: Verificar qual relação entre respostas fisiológicas e psicofisiológicas na intenção de repetir o treinamento de dois protocolos HIIT de mesmo volume load e distintos períodos de trabalho, em adultos treinados de ambos os sexos. Métodos: Em experimento randomizado, a amostra foi composta por 9 indivíduos com idade entre 28±5 anos, massa corporal 69,6±14,2 kg, estatura 169±0,1cm, IMC 24,1±2,3 kg/m2 e percentual de gordura corporal 20,2±7,9% praticantes de exercícios físicos aeróbicos estruturados por pelo menos seis meses. Realizaram dois diferentes protocolos de HIIT em bicicleta ergométrica, sendo (I) protocolo 1:0,5, com intensidade prescrita (80-90% da FCmáx), (II) protocolo 1:2 com intensidade prescrita (all-out) com duração total de esforço de 20 minutos e intervalo de pelo menos 48 horas entre cada sessão. Foram analisados frequência cardíaca (FC), pressão arterial sistêmica (PAS), percepção subjetiva de esforço (PSE), escala visual analógica (EVA), resposta afetiva (FS), divertimento (PACES) e intenção de repetir a sessão. A análise estatística usada foi ANOVA com post-hoc de Tukey (p<0,05). Resultados: As análises da FC, PAS, EVA, PACES e PSE não apresentaram diferença significativa entre os protocolos de treinamento. As respostas afetivas (FS e intenção de repetir) apresentaram maior declínio no protocolo 1:0,5, porém sem significância (p>0,05). Conclusão: Os dados permitem concluir que o protocolo 1:2 provocou maiores perturbações fisiológicas durante esforço e apresentou maior resposta afetiva positiva e intenção de repetir a sessão de exercício, variáveis que podem vir a contribuir na aderência à prática regular de exercícios físicos.
