RESUMO

We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. CONCLUSIONS: PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.

RESUMO

OBJECTIVE: The aim of this study was to explore differences in brain activity and connectivity using simultaneous electroencephalography and near-infrared spectroscopy in patients with focal dystonia during handwriting and finger-tapping tasks. METHODS: Patients with idiopathic right upper limb focal dystonia and controls were assessed by simultaneous near-infrared spectroscopy and electroencephalography during the writing and finger-tapping tasks in terms of the mu-alpha, mu-beta, beta and low gamma power and effective connectivity, as well as relative changes in oxyhemoglobin (oxy-Hb) and deoxyhemoglobin using a channel-wise approach with a mixed-effect model. RESULTS: Patients exhibited higher oxy-Hb levels in the right and left motor cortex and supplementary motor area during writing, but lower oxy-Hb levels in the left sensorimotor and bilateral somatosensory area during finger-tapping compared to controls. During writing, patients showed increased low gamma power in the bilateral sensorimotor cortex and less mu-beta and beta attenuation compared to controls. Additionally, patients had reduced connectivity between the supplementary motor area and the left sensorimotor cortex during writing. No differences were observed in terms of effective connectivity in either task. Finally, patients failed to attenuate the mu-alpha, mu-beta, and beta rhythms during the finger-tapping task. CONCLUSIONS: Cortical blood flow and EEG spectral power differ between controls and dystonia patients, depending on the task. Writing increased blood flow and altered connectivity in dystonia patients, and it also decreased slow-band attenuation. Finger-tapping decreased blood flow and slow-band attenuation. SIGNIFICANCE: Simultaneous fNIRS and EEG may show relevant information regarding brain dynamics in movement disorders patients in unconstrained environments.

RESUMO

Resumo Centrando-se no impacto que a comunicação de risco emitida pelas organizações de saúde pública tem na mudança dos comportamentos da sociedade, esta investigação pretende analisar as mensagens-chave que a Organização Mundial de Saúde (OMS) definiu para promover o programa de vacinação contra a covid-19. Para cumprir este objetivo, enveredou-se por uma metodologia de estudo qualitativa, que privilegiou o uso da análise do conteúdo publicado nas páginas de Facebook e de Instagram da OMS, no período de 1 de abril a 31 de agosto de 2021. No total, foram analisadas 62 publicações. Os resultados mostraram que a OMS utilizou quatro eixo de comunicação para promover a importância da vacinação na sociedade: garantir a credibilidade e a transparência da informação transmitida; certificar a segurança e a eficácia da vacina; apelar ao sentido de responsabilidade coletiva; e associar a vacina à solução para pôr fim à pandemia. As conclusões do estudo mostram que, embora a equidade no acesso à vacina ainda seja uma realidade em construção, os quase 70% da população mundial vacinada sugerem que as mensagens enviadas pela OMS no contexto de comunicação de risco podem ter contribuído para a construção de uma imagem positiva do programa de vacinação.


Abstract Focusing on the impact that risk communication issued by public health organizations brings to changing societal behaviors, this research aimed to analyze the key messages that the World Health Organization (WHO) has defined to promote the COVID-19 vaccination program. In order to achieve this goal, a qualitative study methodology was used to analyze the content published on the WHO's Facebook and Instagram pages from April 1 to August 31, 2021. In total, 62 publications were analyzed. The results showed that the WHO used four key communication messages to promote the importance of vaccination in society: ensuring the credibility and transparency of the information transmitted; certifying the safety and efficacy of the vaccine; appealing to a sense of collective responsibility; and associating the vaccine with the solution to end the pandemic were the chosen communication axes. The conclusions of this study show that, although fair access to the vaccine is still a reality in the making, the fact that almost 70% of the world's population has been vaccinated suggests that the messages sent by the WHO in the context of risk communication may have contributed to building a positive image of the vaccination program.

RESUMO

Introdução: a hanseníase é uma do-ença infecciosa crônica causada pelo Mycobacterium leprae (M. leprae), um para-sita intracelular obrigatório. Assim, a resis-tência do hospedeiro a esse patógeno depen-de da imunidade celular. O uso de modelos experimentais tem permitido o estudo da hanseníase do ponto de vista imunológico, microbiológico e terapêutico, entretanto, as diferenças na progressão da infecção entre os modelos mais empregados (camundongos imunocompetentes, BALB/c, e camundongos congenitamente atímicos, nude) são pouco estudadas. Objetivo: comparar a evolução da infecção pelo M. leprae em camundongos BALB/c e nude quanto à multi-plicação bacilar e avaliação do perfil inflamatório sistêmico pela quantificação sérica de citocinas e óxido nítrico (NO). Métodos: os camundongos foram inoculados com M. leprae nos coxins plantares e avaliados aos 3, 5 e 8 meses após a infecção. Resultados: camundongos nude apresentaram multiplicação bacilar progressiva nos coxins plantares. Em camundongos BALB/c, o número de bacilos foi maior aos 5 meses. Em relação à quantificação de citocinas, nos camundongos BALB/c houve aumento de IL-2 e IL-17A e diminuição de IL-6 e NO aos 8 meses de inoculação. Nos camundongos nude, verificou-se o aumento do TNF aos 8 meses de inoculação e manutenção dos níveis de NO. Conclusão: os resultados encontrados sugerem que em camundongos BALB/c ocorre a ativação de uma resposta imune capaz de controlar a multiplicação do M. leprae, em contrapartida em camundongos nude a infecção é progressiva a despeito de altos níveis de TNF.

Introduction: leprosy is a chronic infectious disease caused by Mycobacterium leprae (M. leprae), an obligate intracellular parasite. Thus, host resistance to this pathogen depends on cellular immunity. The use of experimental models has made it possible to study leprosy from an immunological, microbiological, and therapeutic point of view. However, the differences in the progression of the infection between the most used models (immunocompetent mice, BALB/c, and congenitally athymic mice, nude) have been little studied. Objective: to compare the evolution of M. leprae infection in BALB/c and nude mice in terms of bacillary multiplication and evaluation of the systemic inflammatory profile by quantifying serum cytokines and nitric oxide (NO). Methods: the mice were inoculated with M. leprae in the footpads and evaluated at 3, 5, and 8 months after infection. Results: nude mice showed progressive bacillary multiplication in the footpads. In BALB/c mice, the number of bacilli was higher at 5 months. In terms of cytokine quantification, BALB/c mice showed an increase in IL-2 and IL-17A and a decrease in IL-6 and NO at 8 months of inoculation. In the nude mice, there was an increase in TNF at 8 months of inoculation and maintenance of NO levels. Conclusion: the results suggest that BALB/c mice activate an immune response capable of controlling the multiplication of M. leprae, whereas in nude mice the infection is progressive despite high levels of TNF.

RESUMO

BACKGROUND: This study aims to provide an academic medical overview of the framework and key outcomes of two mammography quality certification programs in Brazil. METHODS: These programs assess radiation dose and phantom image quality in mammography units through a postal system. Each unit that passes this initial assessment is required to submit a sample of copies of five complete examinations. The quality of the patient images and reports is then reviewed by radiologists and medical physicist experts. Additionally, the number of mammography units and mammography coverage in the target population, were assessed. RESULTS: During the study period, 1007 units applied to the certification programs, and 934 (92.8%) successfully passed the assessment of radiation dose and phantom image quality. Out of these, 556 (59.5%) also passed the review of clinical image quality and reports, earning certification. The main issues related to mammogram and report quality were associated with the performance of radiographers (in terms of positioning) and radiologists (in terms of interpretation). On average, there are more than two mammography units/10,000 women in the target group. The screening mammography coverage in this group is 26.3% for women relying exclusively on the public healthcare and 58.1% for women with private healthcare plans. CONCLUSION: This study demonstrates the suitability of the framework adopted by national mammography quality certification programs in a middle-income country. These programs are carried out by relatively small workforce and at reasonable costs, utilizing postal resources to cover the large number of existing mammographic units and the vast distances within the country. POLICY STATEMENT: All mammography services in Brazil must adhere to the quality requirements for examinations and reference values for radiation dose to women established by the Ministry of Health. This ensures standardized conditions for early detection of breast cancer and minimizes the risk associated with x-rays.

RESUMO

Background Blepharospasm is a focal dystonia that affects the orbicularis oculi muscles. The interest in nonmotor symptoms is due to their impact on quality of life. Objective We evaluated the frequency of sleep disorders and circadian rhythm in a sample of Brazilian blepharospasm patients. Methods A total of 51 patients, who met the clinical criteria for blepharospasm, evaluated by 2 specialists in movement disorders, were recruited from the outpatient clinic for movement disorders of two reference centers in the city of São Paulo: Universidade Federal de São Paulo and Hospital do Servidor Público do Estado de São Paulo. The selected 13 patients were evaluated from 13 days before to 13 days after using botulinum toxin. They were interviewed, underwent physical examination and actigraphy, and completed sleep diaries. Results After using botulinum toxin, the group that reported sleep improvement exhibited a 50% decrease in sleep latency. There was no change in restless leg syndrome or circadian rhythm. Patients who reported no sleep improvement after using botulinum toxin presented poorer synchronization of the light-dark cycle. Conclusion Blepharospasm patients have poor sleep quality. About 50% of the patients had sleep improvement after using botulinum toxin. The synchronization of the light-dark cycle should be influenced by this finding.

RESUMO

Plasma exchange (PLEX) is a therapeutic apheresis modality in which the plasma is separated from inflammatory factors such as circulating autoreactive immunoglobulins, the complement system, and cytokines, and its therapeutic effect is based on the removal of these mediators of pathological processes. Plasma exchange is well established for various neurological disorders, and it is applied successfully in central nervous system inflammatory demyelinating diseases (CNS-IDD). It mainly modulates the humoral immune system; thus, it has a greater theoretical effect in diseases with prominent humoral mechanisms, such as neuromyelitis optica (NMO). However, it also has a proven therapeutic effect in multiple sclerosis (MS) attacks. Several studies have suggested that patients with severe attacks of CNS-IDD have poor response to steroid therapy but show clinical improvement after the PLEX treatment. Currently, PLEX is generally established only as a rescue therapy for steroid unresponsive relapses. However, there are still research gaps in the literature regarding plasma volume, number of sessions, and how early the apheresis treatment needs to started. Thus, in the present article, we summarize the clinical studies and meta-analyses, especially about MS and NMO, outlining clinical data regarding the experience with therapeutic PLEX in severe attacks of CNS-IDD, the clinical improvement rates, the prognostic factors of a favorable response, and highlighting the likely role of the early apheresis treatment. Further, we have gathered this evidence and suggested a protocol for the treatment of CNS-IDD with PLEX in the routine clinical practice.


Plasmaférese (PLEX) é um procedimento em que o plasma é separado de fatores inflamatórios como imunoglobulinas autorreativas circulantes, sistema complemento e citocinas, e seu efeito terapêutico se baseia na remoção desses mediadores de processos patológicos. A PLEX está bem estabelecida no tratamento de diversos distúrbios neurológicos, e é utilizada com sucesso em surtos de doenças desmielinizantes inflamatórias do sistema nervoso central (CNS-IDD). A PLEX modula principalmente o sistema imunológico humoral; assim, tem efeito teórico maior em doenças com mecanismos patológicos humorais proeminentes, como a neuromielite óptica (NMO). No entanto tem também efeito terapêutico comprovado em surtos de esclerose múltipla (EM). Estudos sugerem que a corticoterapia é pouco eficaz em pacientes com surtos graves de CNS-IDD, e que estes apresentam melhora clínica após o tratamento com PLEX. Atualmente, a PLEX está geralmente estabelecida apenas como terapia de resgate para surtos não responsivos a corticosteroides. No entanto, há lacunas na literatura sobre a quantidade de troca de volume plasmático, o número de sessões, e o tempo de início da aférese terapêutica. Dessa forma, resumimos neste artigo estudos clínicos e metanálises, especialmente sobre EM e NMO, e delineamos os dados clínicos sobre a experiência com o uso de PLEX em surtos graves de CNS-IDD, as taxas de melhora clínica, os fatores prognósticos para uma resposta favorável, e destacamos o provável papel do tratamento precoce nestes casos. Em um segundo momento, reunimos essas evidências em uma sugestão de protocolo de tratamento de CNS-IDD com PLEX na prática clínica rotineira.

RESUMO

Local therapies are increasingly used for ocular preservation in retinoblastoma. In middle-income countries, these techniques pose specific challenges mostly related to more advanced disease at diagnosis. The Grupo de America Latina de Oncología Pediátrica (GALOP) developed a consensus document for the management of conservative therapy for retinoblastoma. Intra-arterial chemotherapy (OAC) is the preferred therapy, except for those with less advanced disease or age younger than 6 months. OAC allowed for a reduction in the use of external beam radiotherapy in our setting. Intravitreal chemotherapy is the preferred treatment for vitreous seeding. Enucleation is the treatment of choice for eyes with advanced disease.

RESUMO

This study investigated the anti-caries and anti-inflammatory effects of mouthwash formulations containing Punica granatum (pomegranate) peel extract (PPE), sodium-trimetaphosphate, and low concentrations of fluoride. PPE was characterized using high-performance liquid chromatography (ellagic acid and punicalagin). Total phenolics were quantified among formulations, and their stability was analyzed for 28 days. The formulation effects were evaluated as follows: (1) inorganic component concentration and reduced demineralization on bovine enamel blocks subjected to pH cycling; (2) anti-biofilm effect on dual-biofilms of Streptococcus mutans ATCC 25175 and Candida albicans ATCC 10231 treated for 1 and 10 min, respectively; and (3) cytotoxicity and production of inflammatory mediators (interleukin-6 and tumor necrosis factor-alpha). The formulation containing 3% PPE, 0.3% sodium-trimetaphosphate, and 225 ppm of fluoride resulted in a 34.5% surface hardness loss; a 13% (treated for 1 min) and 36% (treated for 10 min) biofilm reduction in S. mutans; a 26% (1 min) and 36% (10 min) biofilm reduction in C. albicans; absence of cytotoxicity; and anti-inflammatory activity confirmed by decreased interleukin-6 production in mouse macrophages. Thus, our results provide a promising prospect for the development of an alcohol-free commercial dental product with the health benefits of P. granatum that have been recognized for a millennium.

RESUMO

Background: The COVID-19 situation in Brazil is complex due to large differences in the shape and size of regional epidemics. Understanding these patterns is crucial to understand future outbreaks of SARS-CoV-2 or other respiratory pathogens in the country. Methods: We tested 97,950 blood donation samples for IgG antibodies from March 2020 to March 2021 in 8 of Brazil's most populous cities. Residential postal codes were used to obtain representative samples. Weekly age- and sex-specific seroprevalence were estimated by correcting the crude seroprevalence by test sensitivity, specificity, and antibody waning. Results: The inferred attack rate of SARS-CoV-2 in December 2020, before the Gamma variant of concern (VOC) was dominant, ranged from 19.3% (95% credible interval [CrI] 17.5-21.2%) in Curitiba to 75.0% (95% CrI 70.8-80.3%) in Manaus. Seroprevalence was consistently smaller in women and donors older than 55 years. The age-specific infection fatality rate (IFR) differed between cities and consistently increased with age. The infection hospitalisation rate increased significantly during the Gamma-dominated second wave in Manaus, suggesting increased morbidity of the Gamma VOC compared to previous variants circulating in Manaus. The higher disease penetrance associated with the health system's collapse increased the overall IFR by a minimum factor of 2.91 (95% CrI 2.43-3.53). Conclusions: These results highlight the utility of blood donor serosurveillance to track epidemic maturity and demonstrate demographic and spatial heterogeneity in SARS-CoV-2 spread.

RESUMO

To investigate a 12-year historical series (2006-2017) of human T-cell lymphotropic virus (HTLV)-positive blood donations from Fundação Hemominas, Minas Gerais, Brazil, an observational retrospective study was performed to evaluate data of blood donor candidates who were screened for HTLV-1/2 by enzyme-linked immunosorbent assay or chemiluminescence assays and confirmed by Western blot. We analyzed 3 309 716 blood donations covering 2006-2017 that were extracted from the institutional database. In a total of 3 308 738 donations that have complete algorithm tests, the global frequency of HTLV-positive donations was 0.012%. The seroprevalence in first-time blood donors was 28.82/100 000 donors; 0.95/100 000 donations were HTLV-positive in repeat blood donors. The frequency of HTLV-seropositive females was significantly higher than males (odds ratio = 1.85, p < 0.001) in first-time donors. The median age of HTLV-positive first-time and repeat donors was similar (36 and 32 years, respectively). First-time donors ≥41 years had higher odds to be infected. There was a clear tendency of decline in the HTLV-positive donations in the period analyzed, going from 19.26/100 000 donations to 8.50/100 000 donations. The increase in the proportion of repeat donors over the period analyzed (from 23% in 2006 to 67% in 2017) must be the principal factor that contributed to this drop. Our results showed a continuous decline in the frequency of HTLV-positive donations from Minas Gerais, Brazil throughout 12 years and emphasize the importance of having a high rate of repeat donors in blood centers to reduce the residual risk of transfusion-transmitted infections.

RESUMO

Biofilm on acrylic resin dental prostheses may cause gingival inflammation. This study evaluated the influence of a silicon dioxide coating layer applied onto acrylic resin on the adhesion of microorganisms. Blocks (5 x 5 x 3 mm) of acrylic resin were evaluated for surface roughness and divided into two groups: control (CG) and coated with silicon dioxide (LG group). The specimens were evaluated by scanning electron microscopy (n = 1) and by contact angle analysis (n = 3). For the in situ study, 20 volunteers wore acrylic palatal devices containing three samples from each group (n = 60) for 2 days. The biofilm formed was quantified by metabolic activity and total biomass using the crystal violet assay. The results were subjected to Bartlett's normality test and Gamma model with random effect for the response variable (α = 5%). The mean contact angle of the coated group was significantly lower than that of the uncoated group (p < 0.05). The metabolic activity of microorganisms in the biofilm on the blocks treated with coating was significantly lower than that of control blocks (p = 0.02). Regarding the amount of extracellular matrix produced by the microorganisms, there was no difference between the CG and LG group (p = 0.05). The application of a silicon dioxide coating on acrylic resin reduced the activity of the polymicrobial biofilm formed in situ. This coating may be advantageous for patients with conventional complete dentures or implants made of acrylic resin and who have motor difficulties that prevent them from cleaning their prostheses properly.

RESUMO

Objetivo: avaliar a espiritualidade e o bem-estar espiritual em estudantes de graduação em enfermagem. Método: estudo quantitativo e observacional com estudantes de enfermagem do primeiro e último ano no primeiro semestre de 2020, de quatro universidades em uma cidade no norte do Estado do Paraná. Foram aplicados e analisados Escala de avaliação da espiritualidade,e Escala de Bem-Estar Espiritual, e apresentados por meio de análise descritiva dos dados. Resultados: 87,8% (n=58) dos participantes têm pensamentos espirituais e 83,4% (n=55) com influência da religiosidade, com alto score de espiritualidade com 22,2 pontos, 54,5% (n=36) apresentaram alto score de bem-estar espiritual classificados como positivo, enquanto 45,5% (n=30) apresentaram score negativo. Conclusão: a maioria dos estudantes se esforçam em viver de acordo com sua crença religiosa, bem como sua vida está baseada na espiritualidade que possui. Na escala de bem-estar espiritual, observou-se pouca diferença entre os índices positivo e negativo no grupo. (AU)

Objective: to evaluate spirituality and well-being spiritual in undergraduate nursing students. Method: quantitative and observational study with first and last year nursing students in the first semester of 2020, from four universities in a city in the north of the state of Paraná. The Spirituality Assessment Scale and the Spiritual Well-Being Scale were applied and treated through descriptive data analysis. Results: 87.8% (n=58) of the participants have spiritual thoughts and 83.4% (n=55) are influenced by religiosity, with a high spirituality score with 22.2 points, 54.5% (n=36) had a high spiritual well-being score classified as positive, while 45.5% (n=30) had a negative score. Conclusion: most students strive to live according to their religious belief, as well as their life is based on the spirituality they have. On the spiritual well-being scale, there was little difference between the positive and negative indices in the group.(AU)

RESUMO

BACKGROUND: Although abnormal movements and postures are the hallmark of dystonia, non-motor symptoms (NMS) are common and negatively affect quality of life. OBJECTIVES: The aim of this study was to screen dystonia patients for NMS and analyze their association with clinical parameters, including motor disability. METHODS: Adult patients with idiopathic isolated dystonia were interviewed and examined. Dystonia severity was evaluated with the Fahn-Marsden Dystonia Rating Scale and the presence of NMS was assessed using a list of 29 complaints. RESULTS: A hundred and two patients (63.7% female) were enrolled. Dystonia began after 20 years of age in 61.8% and was focal or segmental in 82.8% of patients. Only eight patients (7.8%) had no NMS and 59.8% reported more than five. The most prevalent NMS were pain (72.5%) and anxiety (63.7%), followed by difficulty recalling information (44.1%), sadness/anhedonia (41.2%), and difficulty falling asleep (38.2%). No correlation was found between the total number of NMS and dystonia severity (p = 0.18) or regular botulinum toxin use (p = 0.66). The majority of NMS domains correlated with each other. CONCLUSIONS: Our results confirm a high prevalence of NMS among dystonia patients, even in those with mild motor disability. The pathophysiology of NMS in dystonia remains to be completely understood.

RESUMO

BACKGROUND: Fusarium spp. has been considered as an onychomycosis agent, but little is known about the etiopathogenesis of fusarial onychomycosis; thus, the objective of this study was to characterize the fungal-nail interaction and the consequences of the nail infection process by Fusarium oxysporum using the human nail, in an ex vivo model. METHODS: The kinetic of biofilm production and infection by F. oxysporum using the nail as the only nutritional source were evaluated by scanning electron microscopy, number of culturable cells, metabolic activity, characterization of extracellular matrix, spectroscopy and histopathology analyses. RESULTS: After evaluating the biofilm kinetic over 7 days using different parameters and techniques, it was possible to characterize the Fusarium-nail interaction. CONCLUSIONS: This study is a part of a big project aiming to clarify the fusarial pathogenesis and contributes to proving F. oxysporum is able to adapt, grow, develop, and form a biofilm on healthy human nails, which are crucial steps for the invasion process.
