Palatable high-fat diet intake influences mnemonic and emotional aspects in female rats in an estrous cycle-dependent manner.

Worldwide, the excessive consumption of fat and/or sugar has increased considerably. Palatable high-fat diets (HFDs) lead to metabolic disturbances and obesity, and impact emotional and cognitive processes. Previous studies in rodent models suggested that HFDs often cause multiple behavioral alterations, such as learning and memory deficits, and anxiety-like behaviors. Different sexes imply different behavioral and cognitive abilities; yet, most of these studies dealt with male or ovariectomized rats. We evaluated HFD effects in female rats submitted to different behavioral tasks, considering the effects of endogenous hormonal variations throughout estrous cycle. Female Wistar rats in each phase of the estrous cycle using commercial chow (CC) or HFD for 32 days. During treatment, behavioral assessments using sucrose preference (SP), elevated plus-maze (EPM), open field (OF) and novel-object recognition (NOR). At the end of the behavioral tests, animals were euthanized, and performed an immunohistochemical analysis of the brains by brain-derived neurotrophic factor (BDNF) and tyrosine hydroxylase (TH). The main results demonstrated that (1) HFD-fed rats had higher body mass gain and food intake, without altering caloric intake, (2) rats in diestrus had lower sucrose intake, (3) females in metestrus and diestrus showed deficits in the novel-object recognition memory. Furthermore, TH-immunoreactivity decreased in the dorsal striatum and BDNF in the hippocampus in HFD-fed females. These results suggest that HFD alters neurochemical and metabolic aspects that may induce phase-dependent behavioral changes in female rats.

Breast cancer in young women: a rising threat: A 5-year follow-up comparative study.

Introduction: Breast cancer in young women is usually considered as breast cancer occurring in women younger than 40 years and is the most frequent cancer-related cause of death in these patients. In the past few years, there seems to be an increasing trend in the prevalence of breast cancer in young women, which, associated with poorer prognosis, more aggressive histologic features, and more frequent recurrence rates, makes it a rising threat to young women. This study aimed to evaluate the biological behavior of breast cancer in young women in our institution. Material and methods: A retrospective, unicentric, cohort study was conducted between 2012 and 2016. All consecutive patients with breast cancer were enrolled in the study. Cases were divided into two groups: case group, those younger than 40 years, and control group, those 40 years or older. The exclusion criterion was nonoperative treatment. Several clinical and pathologic parameters were evaluated, as well as were overall survival time and disease-free survival time. Results: The incidence of breast cancer in young women presented a rising tendency over the study period. Significant differences were observed in the comparison of the groups according to body mass index, age at menarche, age at birth of the first child, and proliferation rate. There were no differences in overall survival and disease-free survival rates between the groups. Conclusions: Young women had a more symptomatic presentation, a greater tumor proliferation rate, but similar outcomes compared with older patients. Greater multicentric studies are needed to confirm or refute these results.

Primary cutaneous B-cell lymphoma arising from an inguinal hernioplasty scar.

The primary cutaneous B-cell lymphoma (PCBCL) is a rare neoplasm. It is believed that antigenic stimulation and chronic inflammation can be the basis of pathogenesis. Here, we report a case that to our knowledge is the first patient with a presentation of a PCBCL arising from a surgical scar, in particular, an inguinal hernioplasty. The case reminds us of the importance of raising clinical suspicion for malignant neoplasms in surgical scars, in particular, after mesh placement. MeSH terms: 'lymphoma, large b-cell, diffuse', 'skin' and 'cicatrix'.

Sakuranetin exerts anticonvulsant effect in bicuculline-induced seizures.

Epilepsy is a chronic neurological disorder characterized by an abnormal, spontaneous, and synchronized neuronal hyperactivity. Therapeutic approaches for controlling epileptic seizures are associated with pharmacoresistance and side effects burden. Previous studies reported that different natural products may have neuroprotector effects. Sakuranetin (SAK) is a flavanone with antiparasitic, anti-inflammatory, antimutagenic, antiallergic, and antioxidant activity. In the present work, the effect of SAK on seizures in a model of status epilepticus induced by bicuculline (BIC) in mice was evaluated. Male Swiss mice received an intracerebroventricular injection (i.c.v.) of SAK (1, 10, or 20 mg/kg-SAK1, SAK10, or SAK20). Firstly, animals were evaluated in the open field (OF; 20 min), afterwards in the elevated plus maze (EPM) test (5 min). Next, 30 min prior the administration of BIC (1 mg/kg), mice received an injection of SAK (1 or 10 mg/kg, i.c.v.) and were observed in the OF (20 min) for seizures assessment. After behavioral procedures, immunohistochemical analysis of c-Fos was performed. Our main results showed that the lowest doses of SAK (1 and 10 mg/kg) increased the total distance traveled in the OF, moreover protected against seizures and death on the BIC-induced seizures model. Furthermore, SAK treatment reduced neuronal activity on the dentate gyrus of the BIC-treated animals. Taken together, our results suggest an anticonvulsant effect of SAK, which could be used for the development of anticonvulsants based on natural products from herbal source.

Brazilian Protocol for Sexually Transmitted Infections 2020: acquired syphilis.

The Clinical Protocol and Therapeutic Guidelines for Comprehensive Care of People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020, includes updates concerning acquired syphilis. The document comprises rapid test use, safety and efficacy of benzathine benzylpenicillin, case follow-up, neurosyphilis clinical and laboratory management, approaching sex partners, assistance and monitoring of diagnosed pregnant women, and syphilis and HIV co-infection specificities, as well as a case notification summary. Health managers and professionals must be continuously trained so as to integrate care and surveillance, to strengthen actions for efficient control of syphilis, to broaden the search for sex partners, and to expand access of most vulnerable populations to health services. Most people with syphilis are asymptomatic; this contributes to the maintenance of the transmission chain. Without adequate treatment of pregnant women with syphilis, severe consequences can occur, such as miscarriage, prematurity, low birth weight, natimortality, and congenital syphilis.

[Syphilis in young Brazilian military recruits in 2016: sociodemographic, behavioral, and clinical aspects]. / Sífilis em jovens conscritos brasileiros, 2016: aspectos sociodemográficos, comportamentais e clínicos.

The objective was to characterize sociodemographic, behavioral, and clinical aspects in young Brazilian military recruits according to prevalence of syphilis. This was a descriptive study based on a nationwide population-based survey in 2016 with a probabilistic sample of military recruits 17 to 22 years of age. A confidential self-applied questionnaire was used. Blood samples were drawn from participants for treponemal and non-treponemal syphilis tests. Descriptive statistical techniques were used to estimate syphilis prevalence rates and distribution of frequencies between the target variables, considering 95% confidence intervals (95%CI), after weighting the data. Of the total of 37,282 participants, 73.7% were sexually initiated. Prevalence rates for lifetime and confirmed syphilis were 1.6% and 1.1%, respectively. The following population variables showed higher prevalence of syphilis: lack of Internet access at home; initiation of sexual activity before 14 years of age; men who have sex with men; more than five sexual partners; having received presents, drugs, or other incentives in exchange for sex; and prior history of symptoms of sexually transmissible infections. An increase was observed in syphilis in Brazilian military recruits when compared to previous surveys. This increase emphasizes the importance of this sentinel population for performing active surveillance in order to support healthcare strategies for youth, including in the school system.

Analysis of labeling infant's formulas to children allergic to the protein in cow's milk / Análise da rotulagem de fórmulas infantis para lactentes com alergia a proteína do leite de vaca

Introduction: breastfeeding is the most effective way to feed the child in the first six months of life exclusively and up to two years as a complementary form, as it provides a healthy development. However, in some situations it is impossible among them in children with food allergies such as Cow's Milk Protein Allergy (APLV). This condition can be defined as an adverse reaction of the immune system, caused by antigens present in the food that triggers the allergy.Objective: analyze the information on the labeling of infant formulas for infants with allergies to cow's milk protein (APLV), sold in pharmacies in Sobral/CE.Methods: cross-sectional, exploratory, quantitative and qualitative study. After data collection, the labels were analyzed based on a check list composed by the current legislation in accordance with RDC 45/2011, measuring the number of adjustments and inadequacies.Results: of the seven formulas analyzed, five were 100% adequate, when considering all the provisions that made up the check list. Of these were FAB-1 B, FAB-1 C, FAB-1 E, FAB-1 F, FAB-2 A, they were all in accordance with the dimensions established by RDC 45/2011, it is already in relation to formulas with inadequacy we observed that FAB-1 A was 2.22% in dimension two in which the micronutrient riboflavin was above the recommended range and FAB-1 D was 2.22% in dimension two, the carbohydrate macronutrient above the recommended range. In view of this, what we observed was that most of the formulas analyzed were within the labeling standards specified in Resolution RDC 45/2011, despite the many regulatory standards that govern the labeling and marketing of infant foods, it was realized that there is still a need for regulation stricter in this regard so that the legislation is fully complied with.Conclusion: according to what was evaluated about formulas for infants with APLV in relation to the labeling standards of the current legislation, some inadequacies were found. Therefore, this study showed a greater number of non-conformities in relation to the essential characteristics of composition and quality, despite the many regulatory standards that govern the labeling and marketing of infant foods, it is clear that they are still not fully complied with. It was found that we still need to evolve in the Elaboration, execution and inspection of the labels of formulas for infants with Allergy to Cow's Milk Protein (APLV), in order to minimize these non-conformities and offer the best food within the recommended standard, however these studies are necessary in order to better show and discuss the legislation referring to these products.

Introdução: a amamentação é a forma mais eficaz de alimentar a criança nos primeiros seis meses de vida exclusivamente e até os dois anos como forma complementar, pois proporciona um desenvolvimento saudável. No entanto, em algumas situações, é impossível entre eles em crianças com alergia alimentar, como a alergia à proteína do leite de vaca (APLV). Essa condição pode ser definida como uma reação adversa do sistema imunológico, causada por antígenos presentes nos alimentos que desencadeiam a alergia.Objetivo: analisar as informações sobre a rotulagem de fórmulas infantis para lactentes com alergia à proteína do leite de vaca (APLV), comercializadas em farmácias de Sobral/CE.Método: estudo transversal, exploratório, quantitativo e qualitativo. Após a coleta de dados, os rótulos foram analisados com base em um check list composto pela legislação vigente de acordo com a RDC 45/2011, mensurando o número de adequações e inadequações.Resultados: das sete fórmulas analisadas, cinco foram 100% adequadas, quando consideradas todas as disposições que compunham o check list. Destes eram FAB -1 B, FAB -1 C, FAB -1 E, FAB -1 F, FAB -2 A, todos estavam de acordo com as dimensões estabelecidas pela RDC 45/2011, já está em relação às fórmulas com inadequação observamos que FAB-1 A foi de 2,22% na dimensão dois em que a micronutriente riboflavina estava acima da faixa recomendada e FAB-1 D foi de 2,22% na dimensão dois, o macronutriente carboidrato acima da faixa recomendada. Diante disso, o que observamos foi que a maioria das fórmulas analisadas estava dentro dos padrões de rotulagem especificados na Resolução, apesar das inúmeras normas regulamentadoras que regem a rotulagem e comercialização de alimentos infantis, percebeu-se que ainda existe necessidade de regulamentação mais rigorosa nesse sentido, para que a legislação seja integralmente cumprida.Conclusão: de acordo com o que foi avaliado sobre as fórmulas para lactentes com APLV em relação aos padrões de rotulagem da legislação vigente foram encontradas algumas inadequações. Portanto esse estudo apresentou maior número de inconformidades em relação as características essênciais de composição e qualidade, apesar das muitas normas regulamentadoras que regem a rotulagem e comercialização de alimentos infantis, percebe-se que ainda não são totalmente cumpridas. Verificou-se que ainda precisamos evoluir na Elaboração, execussão e fiscalização dos rótulos das fórmulas para lactentes com Alergia a Proteína do Leite de Vaca (APLV), a fim de minimizar essas não conformidades e ofererer o melhor alimento dentro do padrão preconizado, no entanto faz-se necessários estes estudos a fim de mostrar e discutir melhor as legislações referentes a esses produtos.

Human parasitism and toxicosis by Ornithodoros rietcorreai (Acari: Argasidae) in an urban area of Northeastern Brazil.

The soft tick, Ornithodoros rietcorreai, is a parasite of the rodent, Kerodon rupestris, and, to a lesser extent, of bats living in rock cavities in Northeastern Brazil. This report describes the first recorded episodes of human parasitism by this argasid tick, reported to the Brazilian Ministry of Health in September 2017. We assessed outdoor environments, roofs, animal nests and chicken coops in five houses located in an urban area of Russas City, Ceará State, Brazil. Our results confirmed the presence of the tick in two of the assessed houses. The collected specimens were molecularly identified as O. rietcorreai. Of the ten individuals living in the investigated properties, three reported being parasitized by ticks. Although O. rietcorreai ticks were recovered from the evaluated houses, the primary hosts for the ticks were not identified. The retrospective medical records of parasitized individuals reported the following: local pruritus 3/3, malaise 3/3, local edema and erythema 3/3, local rash 3/3, local pain 3/3, slow lesion healing 3/3 and paresthesia 1/3. One of the individuals reported four parasitism episodes (March, June, July and August 2017) and required medical attention and the administration of anti-allergy and anti-inflammatory drugs. The aforementioned reports were the first to address human parasitism, with subsequent toxicosis, by this tick species in Brazilian urban areas. Attention was drawn to the potential consequences of such episodes to the health of previously exposed individuals.

Poorly differentiated vaginal adenocarcinoma with aggressive behavior-Pap smear findings.

Vaginal carcinoma is a rare condition. In this report, we describe a case of a poorly differentiated aggressive adenocarcinoma in a woman with a three month history of vaginal bleeding and a negative Pap smear done six months prior to her consultation. Specular examination showed a normal cervix, but there was a bleeding ulcer (2 cm in diameter) in the upper third of the vagina. Cytology revealed poorly differentiated atypical cells, and the biopsy established a diagnosis of vaginal adenocarcinoma with little differentiation. Within two months, the patient died without diagnosis of a primary tumor site other than the vagina.

Molecular mechanisms underlying hyperoxia acute lung injury.

The management of acute hypoxemic respiratory failure frequently includes the use of supraphysiological fractions of inspired oxygen (FiO2), which can be beneficial in the short-term but not without risks in the long-term, causing acute lung injury (ALI). Over the last few years, much attention has been devoted to the intracellular signaling transduction pathways that lead to hyperoxia-induced cell damage, particularly MAP kinase cascades. Identification of involved signaling molecules and understanding of the regulation of the main signal transduction pathways might provide the basis for improving the outcome of patients under high FiO2 exposure through more effective therapeutic interventions. This review, which includes studies published from 1987 to 2015, presents an overview on recent progresses in the hyperoxia ALI field with special emphasis on potential therapeutic targets and clinical approaches based on the molecular mechanisms underlying hyperoxia-induced inflammation. Further studies are needed to gain deeper insight into controversial molecular mechanisms underlying hyperoxia-induced cell death, which may play a critical role in future pharmacological interventions, as well as into hyperoxia-induced cell damage, that could monitor and therefore prevent hyperoxia ALI.

É necessário capacitar gestores e profissionais de saúde de forma contínua, com vistas à integração entre assistência e vigilância, ao fortalecimento de ações efetivas de controle da sífilis, à abrangência da busca de parcerias sexuais e ao amplo acesso de populações mais vulneráveis aos serviços de saúde.

Abstract The Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Ministry of Health of Brazil in 2020, includes the update on acquired syphilis. The document comprises rapid tests use, safety and efficacy of the administration of benzathine benzylpenicillin, follow-up of cases, clinical and laboratory management of neurosyphilis, approach to sexual partnerships, assistance and monitoring of diagnosed pregnant women, and specificities of syphilis and HIV co-infection, as well as a summary of the notification of cases. It is necessary to train health managers and professionals on a continuous basis, with a view to integrating care and surveillance, strengthening effective syphilis control actions, increasing the search for sexual partnerships, and expanding the access of the most vulnerable populations to health services.

Characterization and Biological Performance of Marine Sponge Collagen

Abstract This study characterized the morphological aspects of marine collagen - spongin (SPG) extract from marine sponges, as well as, evaluating its in vitro and in vivo biological performance. Aplysina fulva marine sponge was used for the SPG extraction. It was investigated the physicochemical and morphological properties of SPG by using scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction and compared to PMMA and bovine collagen. Additionally, the SPG cytotoxicity and its influence on cell proliferation, through in vitro tests. Moreover, the in vivo biological response was investigated using an experimental model of tibial bone defect. The results demonstrated that SPG presented an irregular granular aspect, with a composition of OH, C=O, NH, CN and an amorphous profile. Also, in vitro viability results for the L929 and MC3T3 cell lines cultured with SPG extracts demonstrated normal growth in comparison to controls, except for MC3T3 viability at day 3. For in vivo analysis, using tibial bone defects in rats, SPG treated animals presented an increased rate of material resorption and higher granulation and bone formation deposition in the region of the defect, mainly after 45 days. As a conclusion, SPG was successfully extracted. The in vitro and in vivo studies pointed out that SPG samples produced an increase in L929 and MC3T3 viability and improved the performance in tibial bone defects. It can be concluded that SPG can be used as a bone graft for bone regeneration.

[Cysticercosis research in epileptic patients dwelling in towns of the western Cariri in the State of Paraíba, Brazil]. / Estudo da cisticercose em pacientes portadores de epilepsia residentes em municípios do Cariri paraibano.

This research involved a sample of 110 epileptic patients from western Cariri, Paraíba, Brazil and it has been developed in three successive phases. During the first one, an epidemiological form was applied with the aim of identifying risk factors related to the taeniasis cysticercosis complex in the etiology of the patients' epilepsy. The second phase consisted of immunological exams of 110 patients, by means of the EITB technique to identify the anti-cysticerci serum antibodies, whereas the presence of circulating antigens was verified through the ELISA technique. In the third phase, thirteen patients who were seropositive, were submitted to brain CT scan. Applying the questionnaire enabled us to know some risk factors. The seroprevalence detected was 118.2/1000 inhabitants. Out of the 13 seropositive patients for cysticercosis, 46.1% presented parenchymal cysticercotic damage. Based on these results, we are able to conclude that the studied towns reveal an epidemiological profile which is compatible with the occurrence of the taeniasis cysticercosis complex and cysticercosis plays an important role in the sprouting of epilepsy in these patients.
