ABSTRACT BACKGROUND: Considering the ability of the health and self-management in diabetes questionnaire (HASMID-10) to verify the impact of self-management on diabetes, we highlight its relevance to scientific research and clinical applicability. However, to date, no study has been conducted to scientifically support its use in other languages. OBJECTIVE: To translate, cross-culturally adapt, and validate the HASMID-10 into the Brazilian Portuguese. DESIGN AND SETTING: A translation, cross-cultural adaptation, and validation study conducted at Ceuma University. METHODS: Study was conducted in accordance with the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments. We included participants of both sexes diagnosed with diabetes, aged between 18 and 64 years, and without cognitive deficits or any other limitations that would prevent them from answering the questionnaire. We assessed participants using the problem areas in diabetes (PAID) scale and HASMID-10. We assessed reliability using a test-retest model with a 7-day interval between assessments. We used intraclass correlation coefficient (ICC), 95% confidence interval (CI), standard error of measurement (SEM), minimum detectable difference (MDD), Spearman correlation coefficient, and floor and ceiling effects. RESULTS: Sample comprised 116 participants, most of whom were women, overweight, non-practitioners of physical activity, and nonsmokers. We observed significant correlations (P = 0.006; rho = −0.256) between the HASMID-10 and PAID, adequate reliability (ICC = 0.780) and internal consistency (Cronbach's alpha = 0.796). No ceiling or floor effects were observed. CONCLUSION: HASMID-10 has adequate measurement properties and may be used for Brazilians.

Abstract This study aimed to assess the traumatic dental injuries (TDIs) in permanent dentition among patients who attended at the outpatient clinic of a Brazilian dental school, during the last 20 years, and to investigate factors associated with the severity of these injuries. Clinical records of patients who attended a specialized center for dental trauma care in Brazil presenting at least one TDI in a permanent tooth, between the years 2000 and 2019, were reviewed. The data recorded were sex, age, affected arch, etiology, number, and type of the teeth affected, and classification and severity of the TDIs. The diagnosis and classification of the TDIs were based on the guidelines of the International Association of Dental Traumatology (IADT). The severity of each patient's injuries was defined as mild, moderate, or severe. Descriptive statistics, chi-square and multinomial regression analyses were used to evaluate the results. The significance level was set at 5%. A total of 837 clinical records were included, totaling 2357 teeth. Males were more prevalent than females. The patients' age ranged from 5 to 71 years. The most common traumas were avulsion (n=512) and uncomplicated enamel-dentin fracture (n=488). Univariate analyses showed that there was a statistically significant association between age group (p=0.004), etiology (p=0.000) and number of teeth affected (p=0.000) with severity of dental trauma. In conclusion, TDIs that occurred in Piracicaba and region are epidemiologically similar to those found worldwide, and that more severe injuries are related to age range, etiology and number of teeth affected.

Resumo Esse estudo objetivou avaliar as injúrias dentárias traumáticas (IDTs) na dentição permanente entre os pacientes que compareceram ao ambulatório de uma faculdade de odontologia brasileira, durante os últimos 20 anos, e investigar fatores associados à severidade dessas lesões. Os registros clínicos dos pacientes que compareceram a um centro especializado de atendimento em traumatismo dentário no Brasil apresentando pelo menos uma IDT em dente permanente, entre os anos de 2000 e 2019, foram revisados. Os dados registrados foram sexo, idade, arco dental afetado, etiologia, número e tipo dos dentes afetados, e classificação e severidade das IDTs. O diagnóstico e a classificação das IDTs foram baseados nas diretrizes da Associação Internacional de Traumatologia Dentária (AITD). A gravidade das lesões de cada paciente foi definida como leve, moderada ou severa. Estatísticas descritivas, teste qui-quadrado e análises de regressão multinomial foram usadas para avaliar os resultados. O nível de significância foi fixado em 5%. Um total de 837 registros clínicos foi incluído, totalizando 2357 dentes. O sexo masculino foi mais prevalente que o feminino. A idade dos pacientes variou de 5 a 71 anos. Os traumas mais comuns foram avulsão (n=512) e fratura não-complicada do esmalte-dentina (n=488). As análises univariadas mostraram que houve associação estatisticamente significativa entre a faixa etária (p=0,004), etiologia (p=0,000) e número de dentes afetados (p=0,000) com a gravidade do traumatismo dentário. Em conclusão, as IDTs que ocorreram em Piracicaba e região são epidemiologicamente semelhantes aos encontrados em todo o mundo, e que lesões mais graves estão relacionadas à faixa etária, etiologia e número de dentes afetados.

Abstract Objective The present study aimed to evaluate the effects of GH treatment on the body composition of children born with SGA. Methods This study is a systematic review of the literature. CINAHL, Embase; Medline/Pubmed, Scopus and Web of Science were searched from inception to March 2022. Results Four studies met the inclusion criteria, with an intervention time of 1 to 3 years, using doses from 0.03 to 0.07 mg/kg/day of GH. Bone densitometry by dual-energy X-ray absorptiometry (DXA) with whole-body scans was the most used method to assess body composition. Most studies (n= 3) had SGA children as a control group with the same characteristics as the case group; the mean age was similar between the groups (minimum of 5.1 ± 1.4 years and maximum of 6.7 ± 1 0.8 years) and all participants had an average height ≤ -3DP. The Lean Mass (LM) and Fat Mass (FM) outcomes of the studies were not presented in a standardized manner; thus, they cannot be compared. There was a significant increase in LM in the group treated with GH in relation to the pre-treatment period and in comparison, to the untreated control group. Three studies showed a significant decrease in FM at the end of the intervention period, and in two studies, this decrease occurred in the control group. Conclusions Despite the differences in the presentation of results and in the evaluation periods, the results of the studies showed that growth hormone favors the gain and maintenance of lean mass, and it also affects fat mass reduction and redistribution.

ABSTRACT Introduction: Patients on renal replacement therapy (RRT) and kidney transplant recipients (KTR) present multiple factors that may increase the risk of death from coronavirus disease 2019 (COVID-19). This study aimed to evaluate the incidence and impact of COVID-19 in RRT patients and KTRs. Methods: Between March 2020 and February 2021, we monitored the RRT population of thirteen dialysis facilities that refer patients for transplantation to our center, a tertiary hospital in Southern Brazil. In the same period, we also monitor COVID-19 incidence and mortality in our KTR population. Demographical, clinical, and COVID-19-related information were analyzed. Results: We evaluated 1545 patients in the dialysis centers, of which 267 (17.4%) were infected by COVID-19 and 53 (19.9%) died. Among 275 patients on the kidney transplant waiting list, 63 patients (22.9%) were infected and seven (11.1%) died. COVID-19 was the leading cause of death (29.2%) among patients on the waiting list. Within the population of 1360 KTR, 134 (9.85%) were diagnosed with COVID-19 and 20 (14.9%) died. The number of kidney transplants decreased by 56.7% compared with the same period in the previous twelve months. Conclusion: In the study period, patients on RRT and KTRs presented a high incidence of COVID-19 and high COVID-19-related lethality. The impact on the patients on the transplant waiting list was less pronounced. The lethality rate observed in both cohorts seems to be related to age, comorbidities, and disease severity.

Resumo Introdução: Pacientes em terapia renal substitutiva (TRS) e receptores de transplante renal (RTR) apresentam múltiplos fatores que podem aumentar o risco de óbito por doença do coronavírus 2019 (COVID-19). Este estudo teve como objetivo avaliar incidência e impacto da COVID-19 em pacientes em TRS e RTR. Métodos: Entre Março de 2020 e Fevereiro de 2021, monitoramos a população em TRS de treze unidades de diálise que encaminham pacientes para transplante ao nosso centro, um hospital terciário no Sul do Brasil. No mesmo período, também monitoramos a incidência e mortalidade da COVID-19 em nossa população de RTR. Foram analisadas informações demográficas, clínicas e relacionadas à COVID-19. Resultados: Avaliamos 1545 pacientes nos centros de diálise, dos quais 267 (17,4%) foram infectados pela COVID-19 e 53 (19,9%) foram a óbito. Entre 275 pacientes na lista de espera para transplante renal, 63 (22,9%) foram infectados e sete (11,1%) foram a óbito. COVID-19 foi a principal causa de óbito (29,2%) entre pacientes na lista de espera. Dentre a população de 1360 RTR, 134 (9,85%) foram diagnosticados com COVID-19 e 20 (14,9%) foram a óbito. O número de transplantes renais diminuiu em 56,7% comparado ao mesmo período nos doze meses anteriores. Conclusão: No período do estudo, pacientes em TRS e RTR apresentaram alta incidência de COVID-19 e alta letalidade relacionada à COVID-19. O impacto nos pacientes na lista de espera para transplante foi menos pronunciado. A taxa de letalidade observada em ambas as coortes parece estar relacionada à idade, comorbidades e gravidade da doença.

Chemically modified imidazole molecules: 4-(1H-imidazol-1-yl)aniline, 4-(1H-imidazol-1-yl)benzaldehyde, 4-(1H-imidazol-1-yl)phenol and (4-(1H-imidazol-1-yl)phenyl)methanol were investigated as inhibitors of the copper (Cu0) corrosion in 0.5 mol L-1 H2SO4 medium. The electrochemical corrosion data were obtained by monitoring open circuit potential, linear potentiodynamic polarization and electrochemical impedance spectroscopy techniques, while the computational density functional theory (DFT) method was applied to correlate the electronic properties of the molecules with corrosion inhibition efficiencies. All molecules had inhibited the Cu corrosion, and the inhibition values lied between 80 and 94%. A good correlation between the inhibition efficiencies values and Gibbs adsorption energy was found, showing that the more negative Gibbs energy, better interaction between the corrosion inhibitor with the Cu0 surface, diminishing its corrosion in 0.5 mol L-1 H2SO4 medium. The DFT calculations showed significative differences in electronic and reactivity properties of imidazole and other molecules. The higher corrosion inhibition of imidazole derivates could be explained by electrophilic characteristic of these molecules, since there are empty molecular orbitals spread over mainly in benzene rings that make a metal-ligand charge transfer, receiving electronic density from the copper surface by backbonding, according to the electronic Fukui functions and the potential charge distribution considering the map of electrostatic potential.

This study evaluated the pollutant levels (NO2, SO2, CO, and O3), air quality index (AQI) and the influence of meteorological variables and coronavirus disease (COVID-19) pandemic on the air quality in Rio de Janeiro. The data set used comprises periods before (March-April, 2019) and during pandemic (March-April, 2020). According to the AQI results, on most days, the air quality was ranked as “good”. Brazilian air quality standards for SO2, O3, and NO2 were not exceeded in any of the monitoring stations during partial lockdown, while CO exceeded in all periods in one site due to industrial emission. Comparing both periods, descriptive statistics for the meteorological parameters presented no differences, which suggests similar conditions. However, when evaluated week by week in 2020, weather conditions presented some differences that probably affected pollutant concentrations. The correlations between O3 and NO2 and some meteorological parameters indicate that variations in both favored ozone formation, since it is a photochemical process favored by temperature and solar radiation and that, in Rio de Janeiro, low NO2 concentrations lead to increased O3. The improvements on air quality during the partial lockdown may be attributed mainly to a reduction on emission sources rather than weather conditions.

Abstract This study characterized the beverage of passion fruit and whey protein added with Lacticaseibacillus rhamnosus GG (LGG). The acidity, pH, soluble solids, protein, phenolic compounds, and color of the sample did not differ during the 28 days at 5°C. The LGG counts in the beverage remained >7.70 log CFU/mL during the evaluation period. However, the LGG count was significantly reduced after the in vitro simulated gastrointestinal tract (GIT) evaluation (reduction of 5 logarithmic cycles after processing). On the other hand, the LGG resistance to GIT increased during the shelf-life of the beverage (LGG count of ~ 4.0 log CFU/mL after 28 days). In addition, the LGG count after GIT increased by approximately 2.0 logarithmic cycles when microencapsulation and fermentation technologies were used in beverage processing. Thus, the product has the potential to be commercialized, due to high viability of LGG use to increase the resistance of LGG to GIT.

Abstract Background Infective endocarditis (IE) is a serious disease with a high mortality rate. Antibiotic prophylaxis for bacterial endocarditis before invasive procedures has been recommended in patients with predisposing cardiac conditions since 1960, but contemporary guidelines worldwide have proposed changes. Objective To evaluate the knowledge and pattern of prescription by cardiologists and dentists regarding antibiotic prophylaxis for bacterial endocarditis before risky oral procedures. Methods This is an observational and cross-sectional study. Data were obtained from an online questionnaire, sent to cardiologists and dentists linked to specialty societies, in the first semester of 2021. Data analysis was performed using descriptive statistics, and comparisons between variables were done in an exploratory approach. The significance level adopted was 5%. Results From 613 responders, 82.5% of cardiologists and 79.5% of dentists reported prescribing antibiotic prophylaxis for patients at high and moderate risk for IE. Of dental procedures capable of generating bacteremia, all were correctly identified by more than 50.0% of the sample. As for the habits of daily living, flossing and toothbrushing had almost 50.0% of correct answers, chewing had only 17.3%, and 40.9% reported that none of the actions presented a risk of bacteremia. When comparing variables, the correct prescription of amoxicillin (2 g, 30–60 minutes before the procedure) was more prevalent among cardiologists and in responders with less than 20 years of graduation (p<0.01). Conclusion In the present study, the prescription of antibiotic prophylaxis for IE were frequent for high- and moderate-risk patients, before oral/dental procedures. Partial knowledge was found about endocarditis, which highlights the need for continuous medical/dental education.

This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.nbsp; Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities. nbsp; Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.nbsp; The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.nbsp; The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.nbsp; nbsp;nbsp; Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.

Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidências científicas que as suportam, quanto ao diagnóstico e tratamento da CDC, com especial ênfase na base de racionalidade que a embasou. A DC no século XXI mantém padrão epidemiológico de endemicidade em 21 países da América Latina. Investigadores e gestores de países endêmicos e não endêmicos indigitam a necessidade de se adotarem políticas abrangentes, de saúde pública, para controle eficaz da transmissão inter-humanos da infecção pelo T. cruzi, e obter-se nível otimizado de atendimento aos indivíduos já infectados, com foco em oportunização diagnóstica e terapêutica. Mecanismos patogênicos e fisiopatológicos da CDC foram revisitados após atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistência parasitária tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distúrbios autonômicos e microvasculares. Alguns deles recentemente constituíram alvos potenciais de terapêuticas. A história natural das fases aguda e crônica foi revista, com realce para a transmissão oral, a forma indeterminada e as síndromes crônicas. Metanálises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade após instalação da cardiomiopatia crônica. Condutas terapêuticas aplicáveis aos indivíduos com a FIDC foram abordadas especificamente. Todos os métodos para detectar alterações estruturais e/ou funcionais com variadas técnicas de imageamento cardíaco também foram revisados, com recomendações de uso nos vários cenários clínicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por métodos que detectam fibrose miocárdica. A metodologia atual para diagnóstico etiológico e as consequentes implicações do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. Também o tratamento de pacientes em risco ou com insuficiência cardíaca, arritmias e eventos tromboembólicos, baseado em recursos farmacológicos e complementares, recebeu especial atenção. Capítulos suplementares subsidiaram as condutas aplicáveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grávidas, na reativação da infecção após transplante cardíacos, e outros.nbsp;nbsp;nbsp; Por fim, dois capítulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivíduos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicações médico-trabalhistas completaram esta diretriz.nbsp;

RESUMEN Este trabajo constituye la validación de la segunda etapa del procedimiento de monitoreo de metales pesados en ecosistemas fluviales de Cuba y mide la concentración de siete metales pesados por ICP-MS en muestras de agua recolectadas en la presa Pedroso (provincia de Mayabeque, Cuba) y sus principales tributarios, así como en el músculo ventral de tres especies de peces utilizadas para consumo humano y animal: Oreochromis spp., Tinca tinca y Clarias gariepinus. Los resultados muestran altas concentraciones de Pb en áreas cercanas a la fábrica de pintura (85.5 μg/L), de asfalto (85.5 μg/L) y a la Autopista Nacional (345.8 μg/L). Las concentraciones de metales pesados (mg/kg peso húmedo) en el músculo del pescado fueron: Cr (0.01-0.58), Co (0.01-0.58), Cu (0.23-88.16), Zn (4.9-29.9), As (0.01-0.86), Cd (0.02-2.93) y Pb (0.01-1.23). De acuerdo con las regulaciones cubanas, las concentraciones de Cd no son recomendables para el consumo en el 37.5-44.0 % de los peces evaluados, mientras que el Pb es elevado en el 14-20 % de los mismos. Se presenta riesgo no carcinogénico (HI) en las poblaciones aledañas cuando el consumo de pescado contaminado alcanza los 81 g/día. El riesgo carcinogénico (ELCR) fue estimado en 5.8 × 10-4 de acuerdo con la metodología de la US-EPA. Los pescadores y sus familias son la población en mayor riesgo de padecer una enfermedad crónica o desarrollar cáncer relacionado con la contaminación por metales pesados en el área. Las autoridades gubernamentales y sanitarias fueron informadas y actualmente se toman medidas para evitar el consumo de peces y disminuir el impacto de las fuentes contaminantes.

ABSTRACT This work is a validation of the second step of a heavy metal monitoring procedure in Cuba fluvial ecosystems. Concentrations of seven heavy metals were measured by ICP-MS in water samples collected from the Pedroso reservoir (Mayabeque province, Cuba) and its main tributaries, as well as in edible muscle of three locally consumed fish species: Oreochromis spp., Tinca tinca and Clarias gariepinus. The results show a high concentration of Pb in areas near a paint factory (85.5 μg/L), an asphalt factory and a high traffic area (345.8 μg/L). Metal content (in mg/kg ww) in fish fillet ranged as follows: Cr (0.01-0.58), Co (0.01-0.58), Cu (0.23-88.16), Zn (4.9-29.9), As (0.01-0.86), Cd (0.02-2.93) and Pb (0.01-1.23). According to Cuban regulations, concentrations of Cd in muscle are not safe in 37.5 to 44.0 % of the studied fishes, while Pb is high in 14.0 to 20.0 %. Non-carcinogenic risk (HI) is present when daily intake is above 81 g/day. Carcinogenic risk (ELCR) is calculated to be 5.8 × 10-4 according to the US-EPA methodology. Fishermen families are the most sensitive population sector. Local authorities were informed and different measures were taken to avoid polluted fish consumption and the reduction of pollutant sources.

Resumo Fundamento: O tabagismo geralmente está associado à hipertensão e pode modificar a resposta vasoconstritora. Objetivo: O presente estudo teve como objetivo analisar e comparar a interação do tabagismo passivo e hipertensão sobre os efeitos da epinefrina e felipressina na pressão arterial após injeção intravascular. Métodos: Ratos Wistar machos de 45 dias tiveram a artéria renal principal esquerda parcialmente obstruída e o rim direito removido (modelo 1K1C). Os ratos foram colocados na câmara para exposição ao tabagismo passivo (10 cigarros) durante 10 minutos (6 dias por semana). Ratos hipertensos receberam atenolol (90 mg/kg/dia) por gavagem durante duas semanas. A resposta hipotensora e hipertensiva, a duração da resposta e a frequência cardíaca foram registradas a partir da medida dos valores diretos da pressão arterial. O nível de significância foi de 5%. Resultados: O tabagismo passivo aumentou a resposta hipertensiva máxima à epinefrina em ratos normotensos e ratos 1K1C tratados com atenolol e à felipressina apenas em ratos 1K1C tratados com atenolol; também reduziu a resposta hipotensiva à epinefrina. A epinefrina aumentou a frequência cardíaca em ratos fumantes passivos ou não-fumantes, normotensos e hipertensos. Comparando os dois vasoconstritores, a epinefrina apresentou maior resposta hipertensiva em fumantes normotensos, ratos 1K1C fumantes e não fumantes tratados com atenolol. No entanto, em ratos normotensos e não fumantes, a felipressina apresentou um efeito hipertensivo maior e mais prolongado. Conclusões: Nossos resultados sugerem que o tabagismo passivo pode reduzir a vasodilatação da epinefrina e aumentar a resposta hipertensiva quando comparado à felipressina. Portanto, a felipressina pode ser segura para pacientes hipertensos, com o objetivo de evitar a interação entre taquicardia e atenolol, mas para pacientes normotensos e não-fumantes, a epinefrina pode ser mais segura que a felipressina.

Abstract Background: Cigarette smoking is usually associated with hypertension and may modify vasoconstrictor response. Objective: The present study aimed to analyze and compare the interaction of passive cigarette smoking and hypertension on epinephrine and felypressin blood pressure effects after intravascular injection. Method: 45-day male Wistar rats had the main left renal artery partially constricted and the right kidney removed (1K1C model). Rats were placed in the chamber for exposition to passive cigarette smoking (10 cigarettes) during 10 min (6 days a week). Hypertensive rats received atenolol (90 mg/kg/day) by gavage for two weeks. Hypotensive and hypertensive response, response duration and heart rate were recorded from direct blood pressure values. The significance level was 5%. Results: Passive cigarette smoking increased maximal hypertensive response to epinephrine in normotensive and 1K1C-atenolol treated rats and to felypressin only in 1K1C-atenolol treated rats; it also reduced epinephrine hypotensive response. Epinephrine increased heart rate in normotensive and hypertensive passive smokers or non-smoker rats. Comparing the two vasoconstrictors, epinephrine showed greater hypertensive response in normotensive smokers, 1K1C-atenolol treated smokers and non-smokers. However, in normotensive-nonsmoker rats, felypressin showed a greater and longer hypertensive effect. Conclusions: Our results suggest that passive cigarette smoking may reduce epinephrine vasodilation and increase hypertensive response when compared to felypressin. Therefore, felypressin may be safe for hypertensive patients to avoid tachycardia and atenolol interaction, but for normotensive and non-smoker patients, epinephrine may be safer than felypressin.

RESUMO: A esporotricose é uma micose subcutânea de evolução subaguda a crônica, causada pelo fungo dimórfico e geofílico Sporothrix schenckii. A transmissão zoonótica vem recebendo destaque, tendo os felinos domésticos um importante papel epidemiológico na doença. Este trabalho pesquisa teve como objetivo diagnosticar casos de esporotricose em felinos domésticos atendidos no município de Campos dos Goytacazes/RJ, bem como correlacionar os casos positivos com os sinais clínicos observados nos mesmos, assim como fatores de risco tais quais sexo, animais castrados ou não, dentre outras características. Foram utilizados 100 felinos domésticos, portadores de lesões cutâneas suspeitas de esporotricose, os quais passaram por avaliação clínica minuciosa e preenchimento de fichas individuais. As lesões foram então selecionadas para coleta de material em suabes estéreis e posterior análise laboratorial, através da citologia e cultura fúngica. Dos 100 animais analisados, 66 (66%) foram positivos para Sporothrix spp., sendo 46 (69,6%) machos não castrados, 15 (22,7%) fêmeas não castradas, 4 (6,06%) fêmeas castradas e 1 (1,5%) macho castrado, os quais 89,3% tinham acesso à rua. Quanto à topografia lesional e estado clínico dos animais, 43 (65,2%) apresentavam lesões focais e 23 (34,8%) lesões disseminadas, onde 21 (31,8%) vieram à óbito ou foram submetidos a eutanásia por opção do tutor. Com os resultados dos exames foi possível a adequada prescrição do protocolo terapêutico e acompanhamento de 40 animais (60,6%), e nos casos dos felinos encaminhados (7,5%), foi reportado ao médico veterinário responsável o respectivo diagnóstico para que este escolhesse sua conduta terapêutica.

ABSTRACT: Sporotrichosis is a subcutaneous mycosis of subacute to chronic evolution, caused by the dimorphic and geophilic fungus Sporothrix schenckii. The zoonotic transmission has been highlighted, with domestic cats having an important epidemiological role in the disease. This research aimed to diagnose cases of sporotrichosis in domestic cats treated in the city of Campos dos Goytacazes/RJ, as well as to correlate the positive cases with the clinical signs observed in them, as well as risk factors such as sex, castrated animals or not, among other characteristics. One hundred domestic felines were used, with skin lesions suspected of sporotrichosis, which underwent a thorough clinical evaluation and completion of individual files. The lesions were then selected for material collection in sterile swabs and subsequent laboratory analysis, through cytology and fungal culture. Of the 100 animals analyzed, 66 (66%) were positive for Sporothrix spp., Being 46 (69.6%) uncastrated males, 15 (22.7%) uncastrated females, 4 (6.06%) females castrated and 1 (1.5%) castrated male, 89.3% of whom had access to the street. Concerning the lesion topography and clinical status of the animals, 43 (65.2%) had focal lesions and 23 (34.8%) disseminated lesions, where 21 (31.8%) died or were submitted to euthanasia at the option of tutor. With the results of the exams, it was possible to adequately prescribe the therapeutic protocol and follow up of 40 animals (60.6%), and in the cases of the cats referred (7.5%), the respective veterinarian was informed of the respective diagnosis so that this To choose their therapeutic behavior.

ABSTRACT Ischemia is responsible for many metabolic abnormalities in the heart, causing changes in organ function. One of modifications occurring in the ischemic cell is changing from aerobic to anaerobic metabolism. This change causes the predominance of the use of carbohydrates as an energy substrate instead of lipids. In this case, the glycogen is essential to the maintenance of heart energy intake, being an important reserve to resist the stress caused by hypoxia, using glycolysis and lactic acid fermentation. In order to study the glucose anaerobic pathways utilization and understand the metabolic adaptations, New Zealand white rabbits were subjected to ischemia caused by Inflow occlusion technique. The animals were monitored during surgery by pH and lactate levels. Transcription analysis of the pyruvate kinase, lactate dehydrogenase and phosphoenolpyruvate carboxykinase enzymes were performed by qRT-PCR, and glycogen quantification was determined enzymatically. Pyruvate kinase transcription increased during ischemia, followed by glycogen consumption content. The gluconeogenesis increased in control and ischemia moments, suggesting a relationship between gluconeogenesis and glycogen metabolism. This result shows the significant contribution of these substrates in the organ energy supply and demonstrates the capacity of the heart to adapt the metabolism after this injury, sustaining the homeostasis during short-term myocardial ischemia.
