ABSTRACT

Abstract The phenolic compound content, the antioxidant and α-amylase inhibition potentials of different extracts of the Plectranthus amboinicus, P. barbatus and P. ornatus were evaluated. We also evaluated the influence of plant growth and harvest time on the chemical composition of the essential oil (EO) of P. amboinicus, its antioxidant and anti-Candida activities and the α-amylase and lipoxygenase inhibitions. The turbo-extract of P. barbatus showed the greatest phenolic compound content and antioxidant activity. No α-amylase inhibition activity was observed in the analyzed extracts, but the turbo-extraction and refluxing extracts possessed high antioxidant activities. Protected cultivation and morning harvest conditions gave the best antioxidant activities, which was associated to the highest carvacrol content. P. amboinicus EO antioxidant activity could contribute to the reduction of oxidative stress in diabetes. Causal Candida strains of diabetic foot ulcers showed sensitivity to P. amboinicus EO. C. albicans and C. dubliniensis were the most sensitive of the selected Candida strains. Turbo-extracts or refluxing of the three species extracts and the EO of P. amboinicus should be considered as a potential candidate for the management the complications of type 2 diabetes.

Resumo Introdução a interação complexa entre fatores sociais, psicológicos e biológicos, que resultam na depressão, poderá acelerar a diminuição da capacidade funcional e, consequentemente, a qualidade de vida do idoso. Objetivo Esta pesquisa teve como objetivo investigar os fatores associados aos indicativos de sintomas depressivos de idosos da atenção básica à saúde de um município do noroeste paranaense. Método Estudo epidemiológico, de corte transversal e base populacional realizado em 12 Unidades Básicas de Saúde (UBS), com 654 homens e mulheres idosos. Foi utilizado um instrumento para caracterização do perfil sociodemográfico dos participantes, assim como o instrumento Geriatric Depression Scale (GDS), versão curta. Os dados foram analisados pelo teste de Qui-quadrado e da Regressão de Poisson (p<0,05). Resultados Os resultados evidenciaram que parece existir uma associação dos idosos com boa percepção de saúde (p=0,001), que não ingerem medicamentos (p=0,001), que não sofreram quedas nos últimos seis meses (p=0,011) e que não apresentaram comorbidades (p=0,001), com a ausência de sintomas depressivos. Os idosos com autopercepção de saúde regular (RP = 1,733; 95%IC = 1280-2,347) e ruim (RP = 2,222; 95%IC = 1,525-3,237) demonstraram maior razão de prevalência de presença de indicativo de depressão. Conclusão Conclui-se que os idosos com pior autopercepção de saúde demonstraram maior razão de prevalência de apresentar indicativos de depressão.

ABSTRACT

Introdução: Com a pandemia de coronavírus os pacientes oncológicos, que estão em tratamentos, nos quais a maioria são imunossupressores, se tornaram um grupo muito suscetível a formas graves da infecção. Logo, como forma de proteção e prevenção, a realização de exames de rastreio no ambiente hospitalar foi restringida, atrasando diversos diagnósticos e comprometendo a eficácia de tratamentos. Objetivos: Analisar a produção científica acerca do tema câncer e COVID-19, a fim de contribuir com informações sobre o assunto. Métodos: Revisão sistemática da literatura nas bases de dados SciELO, LILACS e PubMed. Os descritores utilizados foram "câncer" AND "COVID-19" de acordo com o Medical Subject Headings (MeSH) e seus equivalentes para a língua portuguesa, conforme os descritores de Ciências da Saúde (DeCS). Foram incluídos artigos originais em inglês e português, sem delimitação temporal. Resultados: Foram encontrados 1.606 artigos e, após utilizar os critérios de inclusão e exclusão, nove foram incluídos para análise na revisão. Dentre os temas centrais abordados pelos estudos selecionados estão o impacto da pandemia em algumas áreas de acompanhamento do paciente oncológico, como: tratamento, telemedicina, diminuição de funcionários no atendimento ao paciente com câncer, diminuição dos ensaios clínicos, redução dos recursos financeiros e apoio psicológico a essa população. Conclusão: A pandemia afetou diretamente o modo de vida desse grupo, que sofreu com uma redução no atendimento médico e nos recursos dispostos a eles. Portanto, nota-se a necessidade de prestar um cuidado mais específico a esses pacientes em situação tão delicada durante a pandemia.


Introduction: During the coronavirus pandemic, oncological patients, who are undergoing treatments in which the majority are immunosuppressant, have become a group very susceptible to severe forms of the infection. Therefore, as a form of protection, their going to hospital environments were restricted, delaying diagnosis and compromising the effectiveness of treatments. Objectives: This study aims to analyze the scientific about the production of the theme cancer and COVID-19 in order to contribute with informations on the subject. Methods: Systematic review of literature using the SciELO, LILACS and PubMed. The following keywords were used: "cancer" AND "COVID-19" according to the Medical Subject Headings (MeSH) and their translation to the Portuguese. Studies in English and Portuguese from inception were included. Results: 1,606 studies were screened and 9 were included in the systematic review after using the inclusion and exclusion criterias. Among the central themes addressed by the selected studies are the pandemic impacts in areas of monitoring oncological patients, such as: treatment, telemedicine, reduction of employees in the care of cancer patients, reduction of clinical trials, reduction of financial resources, and psychological support to that population. Conclusion: The pandemic directly affected the way of life of this group, which suffered from a reduction in medical care and the resources available to them. Therefore, there is a need to provide more specific care to these patients in such a delicate situation during the pandemic.

ABSTRACT

Aim: The aim of this study was to evaluate the effect of ethanol-conditioned dentin on endodontic sealer penetration into dentinal tubules by confocal laser scanning microscopy (CLSM). Methods: Forty human maxillary anterior teeth were instrumented and divided into four groups (n = 10) according to the drying methods: 1) wet: vacuum only, 2) paper points: vacuum + absorbent paper points, (3) 70% ethanol: 70% ethanol (1 min) + vacuum + absorbent paper points, and (4) 100% ethanol: 100% ethanol (1 min) + vacuum + absorbent paper points. All root canals were filled with resin-based endodontic sealer. Four sections from each third (cervical, middle, and apical) were examined by CLSM. Root canal wall perimeter infiltrated by sealer, maximum depth of sealer penetration, percentage of penetrated area, and fluorescence intensity of rhodamine B were measured. Statistical analysis was performed by analysis of variance and Tukey's tests (α = 0.05). Results: No statistical difference was found when percentage of root canal wall coverage infiltrated by sealer were compared. The groups in which ethanol solutions were used presented greater depth of sealer penetration, higher percentage of penetrated area, and higher fluorescence intensity of rhodamine B (p< 0.05) when compared with the wet and paper point groups. Overall, 100% ethanol produced better results than 70% ethanol, except for rhodamine B intensity (cervical third). In addition, the absorbent paper points drying method behaved better than did vacuum only group, except for rhodamine B intensity (apical third). Conclusion: Ethanol-conditioned dentin improved the penetration of resin-based sealer into dentinal tubules, especially at the concentration of 100%

ABSTRACT

ABSTRACT: Leishmania infantum causes canine leishmaniasis. Using parasitological and molecular analyses, we identified L. infantum in the reproductive organs of male and female dogs. Using histochemistry, immunohistochemistry, and PCR, we examined tissue samples from the reproductive organs of 8 male dogs and 16 female dogs diagnosed with leishmaniasis. Despite the absence of macroscopic or microscopic lesions in these organs, we observed L. infantum amastigotes in tissue samples from the testis and the uterus. PCR and sequencing of these tissues revealed sequences that matched 100% with L. infantum DNA available at GenBank. The presence of L. infantum amastigotes and DNA in testicular and uterine tissue samples suggested that these organs can harbor the parasite without associated macroscopic or microscopic lesions, and this can be especially important in the vertical and venereal transmission of leishmaniasis in dogs.


RESUMO: Leishmania infantum é agente etiológico da leishmaniose canina. Por meio de análises parasitológicas e moleculares, a presença do parasita foi investigada em órgãos reprodutivos de cães machos e fêmeas. Amostras de tecidos dos órgãos reprodutivos de 8 cães machos e 16 fêmeas diagnosticados com leishmaniose foram avaliadas por histoquímica, imunohistoquímica e PCR. Apesar de não terem sido observadas lesões macroscópicas ou microscópicas nos órgãos reprodutivos desses cães, formas amastigotas de L. infantum foram observadas em amostras teciduais do testículo e útero. A PCR e o sequenciamento do DNA extraído desses tecidos revelaram sequências 100% idênticas a L. infantum depositadas no GenBank. Nossos resultados sugerem que os testículos e o útero podem abrigar o parasita, sem associação com lesões macroscópicas ou microscópicas, o que pode ter uma grande importância na transmissão venérea e vertical da leishmaniose entre cães.

ABSTRACT

Aim: The aim was to evaluate the effect of sodium bicarbonate supplementation (NaHCO3) in repetition performance, perceived exertion and blood lactate concentration. Methods: Fourteen trained men (25.14 ± 3.5 years; 85.83 ± 10.18 kg; 1.78 ± 0.06 m; 26.88 ± 3.17 kg/m2) realized two upper-body resistance exercise sessions consisting of 15-RM load and 1 minute of the interval, combining bicarbonate supplementation (BS) or Placebo conditions. Results: After the ANOVA analysis, no difference was found on the total number of repetitions during the session on both BS and Placebo condition (p = 0.11). However, a greater number of total of repetitions on the machine chest fly exercise for BS vs. Placebo condition (p = 0.04) was observed. The perceived exertion increased regardless of the supplementation condition (p < 0.0001). Additionally, for the blood lactate was observed significant increases in BS vs. Placebo condition in the post verification (p = 0.013), corroborated for a bigger area under the curve (AUC) on the BS compared to Placebo (p = 0.026) condition. Conclusion: In conclusion, sodium bicarbonate supplementation was not able to improve performance during a resistance exercise session, except for the single-joint exercise performed with high values of perceived exertion, not altering the perceived exertion, and blood lactate between protocols.(AU)

ABSTRACT

Abstract INTRODUCTION: We sought to determine risk factors (RFs) associated with the presence of antibodies against Leishmania in dogs from a rural area of Ilha Solteira, SP, Brazil. METHODS: Serum samples were collected from 250 dogs and tested using indirect enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence antibody tests (IFATs). Data concerning dogs, their environment, and their owners' knowledge of leishmaniasis were collected using a questionnaire. To determine RFs for contact with the parasite, univariate statistical analysis based on chi-squared and Fisher's exact tests, followed by logistic regression, was used. RESULTS: It was found that 79/250 (31.6%) of the dogs were positive by IFAT, and 72/250 (28.8%) by ELISA. A total of 82/250 dogs (32.8%) were positive in at least one test. The RFs associated with occurrences of Leishmania exposure were large body size (OR = 2.25; 95% CI = 1.26-4.04; p = 0.003), presence of chickens (OR = 1.94; 95% CI = 1.05-3.65; p = 0.023), and lack of knowledge about Leishmania among dog owners (OR = 1.74; 95% CI = 0.96-3.21; p = 0.049). After multivariate analysis, the RFs for occurrence of Leishmania exposure in dogs that remained significantly associated were the dog's size (large dogs) (OR = 1.2; 95% CI = 1.06-1.35; p = 0.003) and presence of chickens on the properties (small farms) (OR = 1.15; 95% CI = 1.02-1.30; p = 0.023). CONCLUSIONS: These results may be useful for improving preventive practices to reduce the incidence of Leishmania exposure among dogs in rural areas.

ABSTRACT

ABSTRACT The diagnosis of multiple sclerosis (MS) has changed over the last decade, but remains a composite of clinical assessment and magnetic resonance imaging to prove dissemination of lesions in time and space. The intrathecal synthesis of immunoglobulin may be a nonspecific marker and there are no plasma biomarkers that are useful in the diagnosis of MS, presenting additional challenges to their early detection. Methods We performed a preliminary untargeted qualitative lipidomics mass spectrometry analysis, comparing cerebrospinal fluid (CSF) and plasma samples from patients with MS, other inflammatory neurological diseases and idiopathic intracranial hypertension. Results Lipid identification revealed that fatty acids and sphingolipids were the most abundant classes of lipids in the CSF and that glycerolipids and fatty acids were the main class of lipids in the plasma of patients with MS. The area under the curve was 0.995 (0.912-1) and 0.78 (0.583-0.917), respectively. The permutation test indicated that this ion combination was useful for distinguishing MS from other inflammatory diseases (p < 0.001 and 0.055, respectively). Conclusion This study concluded that the CSF and plasma from patients with MS bear a unique lipid signature that can be useful as a diagnostic biomarker.


RESUMO Embora o diagnóstico da EM tenha se modificado na última década, ainda tem como requisito básico a demonstração da disseminação no tempo e no espaço, através do quadro clínico e do exame de ressonância magnética. A síntese intratecal de imunoglobulina pode ser um marcador inespecífico e não há biomarcadores plasmáticos que sejam úteis no diagnóstico da EM, impondo desafios à sua detecção precoce. Métodos Realizamos uma análise lipidômica preliminar por espectrometria de massas, não direcionada, qualitativa, comparando amostras de LCR e plasma de pacientes com EM, outras doenças neurológicas inflamatórias e hipertensão intracraniana idiopática (HII). Resultados A identificação lipídica revelou que os ácidos graxos e esfingolipídios foram as classes mais abundantes de lipídios no LCR e que glicerolipídios e ácidos graxos foram a principal classe de lipídios no plasma de pacientes com EM. A AUC foi de 0,995 (0,912-1) e 0,78 (0,583-0,917), respectivamente. O teste de permutação indicou que essa combinação de íons foi útil para distinguir a EM de outras doenças inflamatórias (p < 0,001 e 0,055, respectivamente). Conclusão Este estudo sugere que o líquido cefalorraquidiano (LCR) e o plasma de pacientes com EM possuem uma assinatura lipídica única, pode ser útil como um biomarcador diagnóstico.

ABSTRACT

RESUMO Objetivo: Comparar o impacto de duas estratégias de fast track quanto ao momento de extubação e retirada da ventilação mecânica invasiva de adultos no pós-operatório cardíaco em desfechos clínicos e hospitalares. Métodos: Estudo de coorte retrospectivo com pacientes submetidos à cirurgia cardíaca. Os pacientes foram classificados de acordo com o tempo de extubação em Grupo Controle (extubados após 6 horas de admissão na unidade de terapia intensiva, com tempo máximo de ventilação mecânica de 18 horas), Grupo 1 (extubados em sala de operação após término da cirurgia) e Grupo 2 (extubados em até 6 horas pós-admissão na unidade de terapia intensiva). Os desfechos primários analisados foram: capacidade vital no primeiro dia de pós-operatório, tempo de internamento hospitalar e na unidade de terapia intensiva. Os desfechos secundários foram reintubação, pneumonia adquirida no hospital, sepse e óbito. Resultados: Para os 223 pacientes avaliados, a capacidade vital foi menor nos Grupos 1 e 2 comparados ao Controle (p = 0,000 e p = 0,046, respectivamente). Os dias de internamento em unidade de terapia intensiva foram significativamente menores nos Grupos 1 e 2 quando comparados ao Controle (p = 0,009 e p = 0,000, respectivamente), já os dias de internamento hospitalar foram menores no Grupo 1 quando comparado ao Controle (p = 0,014). Houve associação entre a extubação na sala de operação (Grupo 1) com reintubação (p = 0,025) e complicações pós-cirúrgicas (p=0,038). Conclusão: Pacientes submetidos ao fast track com extubação em até 6 horas apresentaram menor tempo de internamento em unidade de terapia intensiva sem aumentar complicações pós-cirúrgicas e óbito. Pacientes extubados em sala de operação tiveram menor tempo de internamento hospitalar e em unidade de terapia intensiva, mas apresentaram aumento na frequência de reintubação e complicações pós-cirúrgicas.


ABSTRACT Objective: To compare the impact of two fast-track strategies regarding the extubation time and removal of invasive mechanical ventilation in adults after cardiac surgery on clinical and hospital outcomes. Methods: This was a retrospective cohort study with patients undergoing cardiac surgery. Patients were classified according to the extubation time as the Control Group (extubated 6 hours after admission to the intensive care unit, with a maximum mechanical ventilation time of 18 hours), Group 1 (extubated in the operating room after surgery) and Group 2 (extubated within 6 hours after admission to the intensive care unit). The primary outcomes analyzed were vital capacity on the first postoperative day, length of hospital stay, and length of stay in the intensive care unit. The secondary outcomes were reintubation, hospital-acquired pneumonia, sepsis, and death. Results: For the 223 patients evaluated, the vital capacity was lower in Groups 1 and 2 compared to the Control (p = 0.000 and p = 0.046, respectively). The length of stay in the intensive care unit was significantly lower in Groups 1 and 2 compared to the Control (p = 0.009 and p = 0.000, respectively), whereas the length of hospital stay was lower in Group 1 compared to the Control (p = 0.014). There was an association between extubation in the operating room (Group 1) with reintubation (p = 0.025) and postoperative complications (p = 0.038). Conclusion: Patients undergoing fast-track management with extubation within 6 hours had shorter stays in the intensive care unit without increasing postoperative complications and death. Patients extubated in the operating room had a shorter hospital stay and a shorter stay in the intensive care unit but showed an increase in the frequency of reintubation and postoperative complications.

ABSTRACT

Abstract The aim of this study was to compare molecular tests used to diagnose Leishmania spp. in dogs with different stages of infection. Blood and conjunctival swab (CS) samples from dogs classified in four clinical stages were subjected to different PCR protocols (13A/13B, MC1/MC2, LITSR/L5.8S and LEISH-1/LEISH-2 primers). To the study, 22.3% (48/215) of dogs were classified as without clinical signs, 67.5% (145/215) stage I (mild disease), 7.0% (15/215) stage II (moderate disease) and 3.2% (7/215) stage III (severe disease). The results showed that in blood samples, 13A/13B detected a significant higher number of positive dogs in stage I (25/145) and in total (42/215) (p≤0.05). However, when CS samples were tested, no difference was observed (p>0.05). On the other hand, in blood samples, MC1/MC2 detected significantly fewer positive dogs classified as without clinical signs (0/48), in stage I (0/145) and in total (1/215) (p≤0.05). Likewise, in CS samples, this primers showed also lower detection (1/215) (p≤0.05). So than, we can conclude that PCR on blood samples with 13A/13B primers has greater capacity to detect positive dogs, mainly at the initial of clinical disease than do other primers and MC1/MC2 are not a good choice to detect Leishmania infantum infection in dogs.


Resumo O objetivo deste estudo foi comparar testes moleculares usados para diagnosticar Leishmania spp., em cães apresentando diferentes estágios de infecção. Amostras de sangue e suabe conjuntival (SC) de cães classificados em quatro estágios clínicos foram submetidas a diferentes PCRs (primers 13A/13B, MC1/MC2, LITSR/L5.8S e LEISH-1/LEISH-2). Para o estudo, 22,3% (48/215) dos cães foram classificados como sem sinais clínicos, 67,5% (145/215) estágio I (doença leve), 7,0% (15/215) estágio II (doença moderada) e 3,2% (7/215) estágio III (doença grave). Os resultados mostraram que, em amostras de sangue, 13A/13B detectou número significativamente maior de cães positivos no estágio I (25/145) e no total (42/215) (p≤0,05). No entanto, quando as amostras de SC foram testadas, nenhuma diferença foi observada (p>0,05). Por outro lado, no sangue, MC1/MC2 detectou significativamente menos cães positivos sem sinais clínicos (0/48), em estágio I (0/145) e no total (1/215) (p≤0,05). Da mesma forma, em amostras de SC, MC1/MC2 também apresentou menor detecção (1/215) (p≤0,05). Assim, a PCR em amostras de sangue com 13A/13B tem maior capacidade de detectar cães positivos, principalmente no início da doença do que outros primers, e o par de primers MC1/MC2 não é uma boa escolha para detectar infecção por Leishmania infantum em cães.

ABSTRACT

Abstract Visceral leishmaniasis (VL) is a disease caused by the protozoa Leishmania infantum and can cause an inflammatory reaction in the gastrointestinal tract, however the role of granulocytic cells (neutrophils, eosinophils, and mast cells) in the intestine of dogs infected is not fully understood. We performed a quantitative analysis these cells in the intestinal wall of dogs with canine visceral leishmaniasis (CVL). Twenty dogs were assigned to one of three groups: group 1 (G1, n=8), dogs with CVL and L. infantum amastigotes in the intestine; group 2 (G2, n=9), dogs with CVL but without intestinal amastigotes; and group 3 (G3, n=3), uninfected dogs (control group). Granulocytic cells were counted in the crypt-villus unit (mucosa), submucosa, and muscle layer of the intestinal mucosa. Cell counts were higher in the intestinal wall of dogs from G2 followed by G1 and G3 (p≤0.05). In G1, there was a low inverse correlation between parasite burden of the small intestine and granulocyte counts (r= -0.1, p≤0.01). However, in G2 dogs, mast cell and eosinophil numbers showed positive correlation (r=0.85, p≤0.01). The granulocytic cell hyperplasia observed in the intestine of L. infantum-infected dogs suggests that these cells may be involved in the cell-mediated immune response for parasite elimination.


Resumo A leishmaniose visceral (LV) é uma doença causada pelo protozoário Leishmania infantum e pode causar uma reação inflamatória no trato gastrointestinal, entretanto o papel das células granulocíticas (neutrófilos, eosinófilos e mastócitos) no intestino de cães infectados não é totalmente compreendido. Neste estudo realizamos uma análise quantitativa dessas células na parede intestinal de cães com LV. Vinte cães foram distribuídos em três grupos: grupo 1 (G1, n=8), cães com LV e amastigotas de L. infantum no intestino; grupo 2 (G2, n=9), cães com LV, mas sem amastigotas intestinais; e grupo 3 (G3, n=3), não infectados (grupo controle). Células granulocíticas foram contadas na unidade cripta-vilo (mucosa), submucosa e camada muscular da mucosa intestinal. Observamos hiperplasia dessas células na parede intestinal de cães do G2, seguidas das G1 em relação ao G3 (p≤0,05). No G1, houve uma correlação inversa baixa entre a carga parasitária do intestino delgado e a contagem de granulócitos (r= -0,1; p≤0,01). No entanto, nos cães do G2, os números de mastócitos e eosinófilos apresentaram correlação positiva (r=0,85; p≤0,01). A hiperplasia de células granulocíticas observada no intestino de cães infectados por L. infantum sugere que essas células podem estar envolvidas na resposta imune mediada por células para a eliminação do parasita.

ABSTRACT

This study aimed to investigate perceived barriers for physical activity in older adults while in fitness zones (FZ). Participants were 970 older adults, users of 34 out of 57 FZ in the city of Maringá, Paraná, who responded to a sociodemographic questionnaire, the mini-mental state examination and the Questionnaire on barriers for physical activity. The results indicated high indexes of perception of barriers for physical activity in FZ. Older adults with a regular/bad perception of health had fewer barriers, while males, up to 70 years old and who received more than three minimum wage pay per-ceived more barriers (p < 0.05) when compared to other groups, indicating the physical limitations and the fear of getting injured as the most frequent differences. We can conclude that FZ are loca-tions that present a high number of barriers of older adults to be physically active. Moreover, older adults with a certain profile seem to perceive more barriers for the use of FZ, with the most common justification being physical limitations and the fear of getting injured while being physically active


Este estudo teve como objetivo investigar as barreiras percebidas por idosos para a prática de atividade física nas Academia da Terceira Idade (ATI). Participaram da pesquisa 970 idosos usuários de 34 das 57 ATI no município de Maringá, Paraná, os quais responderam um questionário sociodemográfico, o Mini Exame do Estado Mental e o Questionário de Barreiras para a prática da Atividade Física. Os resultados indicaram altos índices de percepção de barreiras para a prática de atividade física nas ATI. Idosos com percepção de saúde regular/ruim apresentam menor índice de barreiras, enquanto homens, idosos até 70 anos e que re-cebem mais de três salários mínimos percebem maiores barreiras (p < 0,05) quando comparado com outros grupos, indicando as limitações físicas e o medo de se lesionar como as diferenças mais frequentes. Conclui-se que as ATI é um local que apresenta grandes barreiras para os idosos praticarem atividade física. Ainda, ido-sos que apresentam um determinado perfil tendem a reconhecer maiores barreiras para a utilização das ATI, tendo como justificativa principalmente as limitações físicas e o medo de se lesionar durante as atividades

ABSTRACT

This study examine the prevalence and factors associated to osteoporosis among older adults users of the primary health care. This cross-sectional study was carried out with 654 older adults (56% women) from primary health care in Maringá, Paraná, Brazil. The instruments used were the sociodemographic questionnaire and the International Physical Activity Questionnaire (IPAQ), short version. Data analysis was conducted through Chi-square test and Binary Logistic Regression (p < 0.05). The results showed a prevalence of 15.6% of older adults who reported the presence of osteoporosis. There was a higher prevalence of women with osteoporosis (p = 0.001), and on the other hand, there was a greater proportion of married elderly individuals (p = 0.003), and elderly with income above three minimum wages (p = 0.020) with absence of osteoporosis. The results showed that women (OR = 4.45; 95%CI: 2.47-8.01) and the older adults who take more than two medications (OR = 1.67; 95%CI: 1.15-2.42) were more likely to present osteoporosis. Older adults who presented a history of falls are 47.0% more likely to present osteoporosis. It was concluded that sex, the amount of medi-cations and the history of falls are associated with the prevalence of osteoporosis in the older adults


Este estudo analisou os fatores associados a prevalência de osteoporose em idosos usuários da Atenção Primária à Saúde. Estudo transversal, realizado com 654 idosos (56% mulheres) da Atenção Primária à Saúde de Maringá, Paraná, Brasil. Os instrumentos utilizados foram o questionário sociodemográfico e o Questionário internacional de atividade física (IPAQ), versão curta. A análise dos dados foi realizada por meio do teste Qui-quadrado e Regressão Logística Binária (p < 0,05). Os resultados mostraram uma prevalência de 15,6% de idosos que relataram a presença de osteoporose. Houve maior prevalência de mulheres com osteoporose (p = 0,001) e, por outro lado, houve maior proporção de idosos casados (p = 0,003) e idosos com renda acima de três salários mínimos (p = 0,020) com ausência de osteoporose. Os resultados mostraram que as mulheres (OR = 4,45; IC95%: 2,47-8,01) e os idosos que tomam mais de dois medicamentos (OR = 1,67; IC95%: 1,15-2,42) foram mais propensos a apresentar osteoporose. Concluiu-se que o sexo, a quantidade de medicamentos e a história de quedas estão associados à prevalência de osteoporose em idosos

ABSTRACT

This study aimed to verify the occurrence of Leishmania spp. and Leishmania (Leishmania) infantum in horses from a visceral leishmaniasis endemic area in Brazil. DNA samples from blood and conjunctival swab (CS) were tested by PCR and Indirect Immunofluorescence Antibody Test (IFAT). Although none of the horses was clinically sick, animals infected by Leishmania spp. were found and some could be characterized as infected by L. (L.) infantum. From 40 horses, 100% of the animals were positive by blood PCR, 90% (36/40) by CS PCR, and 2.5% (01/40) in serodiagnosis, by IFAT. Six from these 40 horses were L. (L.) infantum positive by blood PCR. Direct sequencing and analysis of amplicons resulted in a sequence to evolutionary analysis. Results indicate the presence of Leishmania spp. and L. (L.) infantum infecting healthy horses in Brazil. The presence of Leishmania spp. and L. (L.) infantum DNA in asymptomatic horses suggests that they can be important reservoirs of these parasites, a highly relevant finding for the epidemiological surveillance of the diseases they cause.(AU)


O estudo objetivou verificar a ocorrência de Leishmania spp. e Leishmania (Leishmania) infantum em cavalos de uma região endêmica para leishmaniose visceral do Brasil. Amostras de DNA de sangue e suabe conjuntival (SC) foram testadas pela PCR e pela Reação de Imunofluorescência Indireta (RIFI). Embora nenhum cavalo estivesse clinicamente doente, animais infectados por Leishmania spp. e L. (L.) infantum foram encontrados em Ilha Solteira/SP. Dos 40 cavalos, 100% (40/40) foram positivos pela PCR de sangue, 90% (36/40) pela PCR de SC, e 2,5% (01/40) no sorodiagnóstico, pela RIFI. Seis desses 40 cavalos foram positivos para L. (L.) infantum pela PCR de sangue. O sequenciamento direto e a análise dos amplicons resultaram em uma sequência para análise evolutiva. Os resultados indicam a presença de Leishmania spp. e L. (L.) infantum infectando cavalos saudáveis no Brasil. A presença de DNA de Leishmania spp. and L. (L.) infantum em cavalos saudáveis sugere que eles podem ser importantes reservatórios desses parasitas, um achado altamente relevante para a vigilância epidemiológica das doenças que causam.(AU)

ABSTRACT

O objetivo desse estudo foi avaliar as concentrações séricas de estradiol, progesterona e prolactina, bem como a expressão gênica dos receptores de estrógeno α e β e de progesterona em cadelas com neoplasias mamárias. Foram utilizadas 60 cadelas adultas, sem raça definida que foram distribuídas em dois grupos. O Grupo I constituído por 30 cadelas portadoras de neoplasias mamárias e o Grupo II constituído por 30 cadelas saudáveis, não portadoras de neoplasia. Para os tutores, foram aplicados questionários sobre fatores epidemiológicos da doença. Após avaliação dos exames pré-operatórios, as cadelas com neoplasia mamária foram submetidas à mastectomia, coletaram-se fragmentos das neoplasias e linfonodos regionais, os quais foram processados para análise histopatológica. Para as dosagens hormonais de estradiol, progesterona e prolactina foram colhidas amostras de sangue em tubos sem anticoagulante e os soros foram submetidos à técnica de eletroquimioluminescência. A expressão gênica dos receptores hormonais foi realizada por meio da técnica de Real-time PCR e para isso foram coletados fragmentos das neoplasias mamárias e extraído o RNA para obtenção do cDNA. A expressão do mRNA para os REα, REβ e RP foi avaliada a partir da amplificação desses genes utilizando primers específicos. Verificaram-se maiores níveis séricos de estradiol (média de 38,98±13,68pg/mL) em cadelas portadoras de neoplasias mamárias malignas quando comparadas as cadelas do grupo controle (p<0,05). Já os níveis séricos de prolactina foram maiores (média de 0,231±0,201ng/mL) nas cadelas que não possuíam neoplasias mamárias quando comparadas ao Grupo I (p<0,05). Para os níveis de progesterona não foram observadas diferença entre os diferentes grupos (p>0,05). Tanto os tumores malignos como os benignos expressaram REα, REβ e RP, não havendo diferença (p>0,05) na expressão entre tumores malignos ou benignos ou relacionada aos outros fatores prognósticos investigados (estadiamento clínico, presença de ulceração, vascularização e tempo de evolução do processo). Os níveis séricos de estradiol aumentaram significativamente com o estadiamento clínico da doença (p<0,05). Verificou-se moderada correlação negativa entre os níveis séricos de estradiol e prolactina. Dessa forma, conclui-se que as dosagens séricas de estradiol e PRL foram influenciadas pela malignidade do tumor e pelo estadiamento clínico das neoplasias. Os receptores hormonais foram expressos pelas neoplasias, independentemente do tipo tumoral e não estão associados aos outros fatores prognóstico clássicos, como presença de ulceração, vascularização ou estadiamento clínico.(AU)


The aim of this study was to evaluate the serum concentrations of estradiol, progesterone, prolactin, the gene expression of estrogen α and β and progesterone receptors in bitches with mammary neoplasms. Sixty adult crossbred bitches distributed in two groups were used. Group I consisted of 30 bitches with mammary neoplasms and Group II consisted of 30 healthy bitches without neoplasia. For the tutors, interviews were made about the disease epidemiology. After preoperative examinations, bitches with mammary neoplasia were submitted to mastectomy; fragments of the neoplasms and regional lymph nodes were collected and processed for histopathological analysis. Blood samples were collected in tubes without anticoagulant and the serum was analyzed by electrochemiluminescence to measure estradiol, progesterone and prolactin. The gene expression of the hormonal receptors was performed by means of the Real-time PCR technique, thus fragments of mammary neoplasms were collected and the RNA was extracted to obtain cDNA. Expression of the mRNA for ERα, ERβ and PR was assessed from the amplification of these genes using specific primers. Higher serum levels of estradiol (mean 38.98±13.68pg/mL) were observed in bitches with malignant neoplasms when compared to the control bitches (p<0.05). Serum prolactin levels were higher (mean of 0.231±0.201ng/mL) in bitches that did not have mammary neoplasms when compared to Group I (p<0.05). No difference was observed for related to the progesterone levels between the groups (p>0.05). Both malignant and benign tumors expressed ERα, ERβ and RP with no statistical difference (p>0.05) and there were no difference related to the other prognostic factors investigated (clinical staging, presence of ulceration, vascularization and aging of neoplasms). Serum estradiol levels increased significantly with the clinical staging of the disease (p<0.05). There was a moderate negative correlation between serum levels of estradiol and prolactin. It was concluded that serum levels of estradiol and PRL were influenced by tumor malignancy and clinical staging of neoplasms. Hormonal receptors were expressed by neoplasms, regardless of tumor type and are not associated with other classical prognostic factors, such as ulceration, vascularization or clinical staging.(AU)

ABSTRACT

Abstract This study aimed to evaluate the influence of different ethanol concentrations on dentin roughness, surface free energy, and contact angle between AH Plus and the root canal dentin. One hundred human maxillary anterior teeth were split longitudinally and 200 dentin specimens were polished to make the surface flatter and smoother. An acrylic bar was positioned between two dentin specimens and impression material was added to create a block, simulating an instrumented root canal space. Specimens were removed from the mold and cleaned in an ultrasonic bath for 10 min. Thereafter, dentin specimens were divided into four groups (n = 50) according to the drying methods used: a) wet: vacuum only, b) paper points: vacuum + absorbent paper points, c) 70% alcohol: 70% alcohol (1 min) + vacuum + absorbent paper points, and d) 100% alcohol: 100% alcohol (1 min) + vacuum + absorbent paper points. A rugosimeter and a goniometer were used to verify the roughness (Ra) and to measure the surface free energy and the contact angle between the AH Plus sealer and the root canal dentin. ANOVA and Tukey tests (α = 0.05) were used for statistical analysis. The 70% and 100% ethanol groups showed significantly decreased roughness as well as increased surface free energy in the root canal dentin when compared to the wet and paper point groups. In addition, ethanol significantly reduced the contact angle between the AH Plus sealer and the root canal dentin. Ethanol solutions (70% and 100%) provide better wettability of AH Plus sealer on dentin surfaces.

ABSTRACT

Abstract This study was about a semi-quantitative analysis of T lymphocytes (CD4+ and CD8+, FoxP3+ regulatory T cells), and macrophages in the gut wall of dogs naturally infected with Leishmania infantum. Thirteen dogs were divided into three groups: group 1 (G1, n=5), dogs with canine visceral leishmaniasis (CVL) and infected with L. infantum amastigotes in the intestine; group 2 (G2, n=5), dogs with CVL but without intestinal amastigotes; and group 3 (G3, n=3), uninfected dogs (control group). There was no significant difference (p ≥ 0.05) on CD4+ and Treg cell numbers among the groups, whereas the levels of CD8+ T cells and macrophages were significantly higher in dogs from G1 group than in G2 and G3 (p ≤ 0.05), especially in intestinal segments with high parasite burden. Parasite burden correlated positively with levels of CD8+ T cells and macrophages (p ≤ 0.05), but was inversely correlated to levels of CD4+ T lymphocytes and FoxP3+ Treg cells. In conclusion, in the intestine of dogs with CVL, the increase of CD8+ T cells and macrophages population associated with high parasite burdens, but no changes of CD4+ T cells and FoxP3+ Treg cells suggest a possible immunoregulation by the parasite not dependent on Treg cells.


Resumo Este estudo foi uma análise semi-quantitativa de linfócitos T (CD4+, CD8+ e regulatórios - Treg FoxP3+) e macrófagos na parede intestinal de cães naturalmente infectados com Leishmania infantum. Treze cães foram divididos em três grupos: grupo 1 (G1, n=5) continha cães com leishmaniose visceral canina (LVC) e com amastigotas intestinais; grupo 2 (G2, n=5) continha cães com LVC, mas sem amastigotas intestinais e o grupo 3 (G3, n=3) continha cães não infectados (grupo controle). Verificou-se que não houve diferença significativa (p ≤ 0.05) no número de células CD4+ e de Treg entre os grupos, mas o número de células T CD8+ e macrófagos foi significativamente superior nos cães do grupo G1 em relação ao G2 e ao G3 (p ≤ 0,05), especialmente nos segmentos intestinais com altas cargas parasitárias. As altas cargas parasitarias correlacionaram positivamente com os números de CD8+ e macrófagos (p ≤ 0,05), mas negativamente com as células CD4+ e Treg. Em conclusão, no intestino dos cães com LVC, o aumento das populações de células T CD8+ e de macrófagos associado a altas cargas parasitárias, mas nenhuma alteração de células T CD4+ e células Treg FoxP3+ sugerem uma possível imunorregulação pelo parasita não dependente de células Treg.
