RESUMO
BACKGROUND: Males have higher weight and length at birth than females. AIM: To verify the influence of the Y chromosome and the action of intrauterine androgens on weight and length at birth of children with Disorders of Sex Development (DSD). SUBJECTS AND METHODS: A cross-sectional and retrospective study. Patients with Turner syndrome (TS), complete (XX and XY), mixed (45,X/46,XY) and partial (XY) gonadal dysgenesis (GD), complete (CAIS) and partial (PAIS) androgen insensitivity syndromes and XX and XY congenital adrenal hyperplasia (CAH) were included. Weight and length at birth were evaluated. RESULTS: Weight and length at birth were lower in TS and mixed GD when compared to XY and XX DSD cases. In turn, patients with increased androgen action (117 cases) had higher weight and length at birth when compared to those with absent (108 cases) and decreased (68 cases) production/action. In birthweight, there was a negative influence of the 45,X/46,XY karyotype and a positive influence of increased androgen and gestational age. In birth length, there was a negative influence of the 45,X and 45,X/46,XY karyotypes and also a positive influence of increased androgen and gestational age. CONCLUSIONS: The sex dimorphism of weight and length at birth could possibly be influenced by intrauterine androgenic action.

OBJECTIVES: This study aimed to determine the effect of several factors on the uptake of tetanus vaccination in pregnant women. STUDY DESIGN: This is a systematic review and meta-analysis of the global literature. METHODS: The search strategy was carried out in the EMBASE and MEDLINE (Pubmed) databases, without language restrictions. The databases were searched from the beginning until May 2020. Fixed and random effect models were applied according to the methodological heterogeneity between the included studies. The I2 test was performed to assess the magnitude of the heterogeneity. The results were presented as a grouped odds ratio (OR) with a 95% confidence interval (CI) and a significance level of 0.05. RESULTS: The initial search strategy generated 14,349 original articles. In total, 31 studies met all inclusion criteria and 20 articles were included in the meta-analysis. The grouped and subgroup analyses showed a significant association between tetanus vaccination and the following factors: higher number of prenatal visits (OR: 2.00; 95% CI: 1.17-3.42), higher maternal age (OR: 1.24, 95% CI: 1.02-1.50), being single (OR: 1.41; 95% CI: 1.20-1.65), professional vaccine guidance (OR: 9.00; 95% CI: 1.81-44.75) and uptake of influenza vaccine (OR: 5.87; 95% CI: 1.39-24.73). CONCLUSIONS: The uptake of tetanus vaccine in pregnant women is associated with various factors. The identification of these factors is an important step towards the implementation of public health strategies aimed at improving immunisation against tetanus in pregnant women.

O linfoma é a neoplasia hematopoiética mais frequentemente diagnosticada na clínica de pequenos animais, sendo caracterizado por uma proliferação descontrolada de linfócitos, acometendo principalmente animais idosos. Dentre os achados clínicos mais comuns da doença, a linfadenopatia periférica recebe destaque. Manifestações clínicas como perda de peso, anorexia, edema subcutâneo, êmese, massas cutâneas, disfagia, ascite e dispnéia são também frequentemente encontradas. O diagnóstico dos linfomas é de extrema importância, sendo primordial para estabelecimento do prognóstico do animal, podendo ser feito através da análise citomorfológica de amostras obtidas por punção aspirativa e avaliação histopatológica. A poliquimioterapia é realizada como protocolo terapêutico de eleição para animais com linfoma. Foi atendido no Serviço de Clínica e Cirurgia Oncológica do Hospital Veterinário da Universidade Federal de Uberlândia (HV-UFU), um Buldogue Inglês, de dois anos de idade, apresentando linfonodonomegalia generalizada e diagnosticado com linfoma difuso de grandes células. O diagnóstico foi obtido por exame histopatológico e o imunohistoquímico revelou imunofenotipagem B. O paciente foi submetido a quimioterapia, sendo escolhido o protocolo Winscosin (CHOP) de 19 semanas com remissão completa ao término do protocolo. O objetivo deste trabalho é relatar um caso de linfoma difuso de grandes células em um Buldogue Inglês de dois anos de idade com remissão completa após a realização de quimioterapia.
Lymphoma is the hematopoietic neoplasm most frequently diagnosed in the clinic of small animals, being characterized by an uncontrolled proliferation of lymphocytes, affecting mainly elderly animals. Among the most common clinical findings of the disease, peripheral lymphadenopathy is highlighted. Clinical manifestations such as weight loss, anorexia, subcutaneous edema, emesis, skin masses, dysphagia, ascites and dyspnea are also frequently encountered. The diagnosis of lymphomas is extremely important, being essential for establishing the animal's prognosis and can be done through cytomorphological analysis of samples obtained by aspiration puncture and histopathological evaluation. Polychemotherapy is performed as the therapeutic protocol of choice for animals with lymphoma. It was treated at Serviço de Clínica e Cirurgia Oncológica do Hospital Veterinário da Universidade Federal de Uberlândia (HV-UFU), a two-year-old English Bulldog, with generalized lymph node enlargement and diagnosed with diffuse large cell lymphoma. The diagnosis was obtained by histopathological and immunohistochemical examination and revealed immunophenotyping B. The patient underwent chemotherapy, and the 19- week Winscosin (CHOP) protocol was chosen with complete remission at the end of the protocol. The aim of this work is to report a case of diffuse large cell lymphoma in a two-year-old English Bulldog with complete remission after chemotherapy.

The efficacy of an antisepsis protocol comprising chlorhexidine gluconate and ethyl alcohol in combination with prophylactic antimicrobial therapy in controlling surgical site infection in horses was studied. To that purpose, seven mixed breed horses received potassium penicillin and gentamicin at least 30 minutes prior to surgery. The surgical site was scrubbed with chlorhexidine gluconate and rinsed with ethyl alcohol. Samples were collected at four time points: (A) - before and (B) - immediately following shaving of the hair coat, (C) - at the end of antisepsis procedures, and (D) - at the end of the surgical procedure. Duration of surgery was recorded. Samples were cultured in three different culture mediums: Mitis Salivarus (Streptococcus sp.), Staphylococcus 110 (Staphylococcus sp.), and Mac Conkey (Enterobacteria). A high level of bacterial growth was observed in all culture mediums at (A) and (B), with no bacterial growth in (C). Staphylococcus sp. growth was observed in (D) in a single patient whose surgical procedure lasted for 120 minutes. Shaving of the hair coat reduced microbial flora on the surface of the skin. Antisepsis in combination with prophylactic antimicrobial therapy was effective in controlling surgical site infection in elective procedures with an average duration of 90 minutes.(AU)
Objetivou-se averiguar a eficácia do protocolo de antissepsia com clorexidina degermante e álcool etílico hidratado 70%, em associação com terapia antimicrobiana profilática, no controle microbiano do foco cirúrgico de equinos submetidos a procedimentos cirúrgicos. Foram utilizados 07 cavalos adultos de raças variadas, onde ambos receberam o mesmo tratamento (terapia antimicrobiana profilática e antissepsia com clorexidina degermante 2% e álcool etílico hidratado 70%), coletando-se amostras em quatro tempos distintos [(A - antes da tricotomia), (B - imediatamente após tricotomia), (C - ao término da antissepsia), (D - ao término do procedimento cirúrgico)]. O tempo de cada procedimento cirúrgico foi contabilizado. Foram utilizados três meios de cultura diferentes, cada um com especificidade para um tipo de crescimento bacteriano. Constatou-se alta incidência de crescimento bacteriano nos três meios utilizados nos tempos de coleta A e B. Para o tempo C, não foi observado crescimento bacteriano. No tempo D averiguou-se crescimento bacteriano do tipo Staphylococcus sp. em um único paciente, cujo tempo cirúrgico foi de 120 minutos de duração. Desta forma, a tricotomia reduziu a carga microbiana na superfície da pele. A antissepsia associada à terapia antimicrobiana profilática mostrou-se eficaz no controle microbiano do foco cirúrgico em procedimentos eletivos, com duração média de 90 minutos.(AU)

Leaf gas exchanges, carbohydrate metabolism and growth of three Brazilian Cerrado invasive African grasses were evaluated after growing for 75 days under doubled CO2 concentration and temperature elevated by 3⯰C. Results showed that although the species presented photosynthetic C4 metabolism, they all had some kind of positive response to increased CO2. Urochloa brizantha and Megathyrsus maximus showed increased height for all induced environmental conditions. Urochloa decumbens showed only improvement in water use efficiency (WUE), while U. brizantha showed increased CO2 assimilation and M. maximus presented higher biomass accumulation under doubled CO2 concentration. The most significant improvement of increased CO2 in all three species appears to be the increase in WUE. This improvement probably explains the positive increase of photosynthesis and biomass accumulation presented by U. brizantha and M. maximus, respectively. The increase in temperature affected leaf carbohydrate content of M. maximus by reducing sucrose, glucose and fructose content. These reductions were not related to thermal stress since photosynthesis and growth were not harmed. Cellulose content was not affected in any of the three species, just the lignin content in U. decumbens and M. maximus. All treatments promoted lignin content reduction in U. brizantha, suggesting a delay in leaf maturation of this species. Together, the results indicate that climate change may differentially promote changes in leaf gas exchanges, carbohydrate content and growth in C4 plant species studied and all of them could benefit in some way from these changes, constituting a threat to the native Cerrado biodiversity.

Resistant hypertension (RHTN) includes patients with controlled blood pressure (BP) (CRHTN) and uncontrolled BP (UCRHTN). In fact, RHTN patients are more likely to have target organ damage (TOD), and resistin, leptin and adiponectin may affect BP control in these subjects. We assessed the relationship between adipokines levels and arterial stiffness, left ventricular hypertrophy (LVH) and microalbuminuria (MA). This cross-sectional study included CRHTN (n=51) and UCRHTN (n=38) patients for evaluating body mass index, ambulatory blood pressure monitoring, plasma adiponectin, leptin and resistin concentrations, pulse wave velocity (PWV), MA and echocardiography. Leptin and resistin levels were higher in UCRHTN, whereas adiponectin levels were lower in this same subgroup. Similarly, arterial stiffness, LVH and MA were higher in UCRHTN subgroup. Adiponectin levels negatively correlated with PWV (r=-0.42, P<0.01), and MA (r=-0.48, P<0.01) only in UCRHTN. Leptin was positively correlated with PWV (r=0.37, P=0.02) in UCRHTN subgroup, whereas resistin was not correlated with TOD in both subgroups. Adiponectin is associated with arterial stiffness and renal injury in UCRHTN patients, whereas leptin is associated with arterial stiffness in the same subgroup. Taken together, our results showed that those adipokines may contribute to vascular and renal damage in UCRHTN patients.
