Nutritive Value and Bioactivities of a Halophyte Edible Plant: Crithmum maritimum L. (Sea Fennel).

Crithmum maritimum L. (sea fennel), an edible xerophyte of coastal habitats, is considered an emerging cash crop for biosaline agriculture due to its salt-tolerance ability and potential applications in the agri-food sector. Here, the nutritional value and bioactive properties of sea fennel are described. Sea fennel leaves, flowers, and schizocarps are composed of carbohydrates (>65%) followed by ash, proteins, and lipids. Sea fennel's salty, succulent leaves are a source of omega-6 and omega-3 polyunsaturated fatty acids, especially linoleic acid. Extracts obtained from flowers and fruits/schizocarps are rich in antioxidants and polyphenols and show antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermis, Candida albicans, and Candida parapsilosis. Plant material is particularly rich in sodium (Na) but also in other nutritionally relevant minerals, such as calcium (Ca), chlorine (Cl), potassium (K), phosphorus (P), and sulfur (S), beyond presenting a potential prebiotic effect on Lactobacillus bulgaricus and being nontoxic to human intestinal epithelial Caco-2 model cells, up to 1.0% (w/v). Hence, the rational use of sea fennel can bring nutrients, aroma, and flavor to culinary dishes while balancing microbiomes and contributing to expanding the shelf life of food products.

The Influence of Time and Temperature on Human Milk Storage Antioxidant Properties, Oxidative Stress, and Total Protein.

BACKGROUND: Human milk is an essential source of nutrition for an infant's health. When breastfeeding working mothers or students, for example, are unable to breastfeed, storing their milk is recommended. Therefore, it is crucial to know the storage conditions to ensure their antioxidant capacity and avoid oxidative damage. RESEARCH AIM: To evaluate the stability of the antioxidant and pro-oxidant profiles and the amount of total protein in fresh human milk after different storage times (1, 2, 7, 14, and 21 days) and temperatures (4 ºC and -20 ºC). METHODS: This was a prospective, longitudinal, and observational study with milk samples grouped according to age for comparisons, which included 20 lactating women. The antioxidant activity was evaluated using the colorimetric methods of free radical scavenging 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid and the decrease of ferric ion. Oxidative stress was determined by the lipid peroxidation product formation through malondialdehyde concentration, and the total protein content was assessed by the Bradford method. RESULTS: The antioxidant profile of human milk was maintained with minimal losses until the 14th day when stored at 4 ºC and -20 ºC. The evolution of malondialdehyde concentration over storage revealed significant changes only 21 days after human milk storage at 4 ºC. There was no change in the value of total protein content. CONCLUSIONS: To sum up, there is no difference in the storage of human milk at a temperature of 4 °C or -20 °C over 14 days. Therefore, the lactating woman may choose the most convenient way of storage.

The role of pacas of captivity as a potential reservoir of zoonotic fungi in Acre, Western Amazon, Brazil / O papel de pacas de cativeiro como potencial reservatório de fungos zoonóticos no Acre, Amazônia Ocidental, Brasil

Wild animals can be natural reservoirs of different microorganisms, essential for monitoring these pathogens for the generation of knowledge and creation of tools aimed at programs for the prevention and control of infectious diseases, including zoonoses. The objective was to report the fungal diversity in the skin of pacas in captivity in Acre, Western Amazon, Brazil. Twenty-six animals were evaluated, from which skin samples were collected by superficial scraping, hair avulsion, and sterile plastic brush. The samples were seeded on Mycosel agar, and the phenotypic characteristics of the colonies were analyzed. In 80.8% of the samples, different fungi were isolated, from the genera Candida, Microsporum,and Trichophyton, among others. This is the first description of the identification of fungi in the skin of pacas and suggests that these animals can be considered essential reservoirs of saprophytic or pathogenic microorganisms with zoonotic potential in the Western Amazon.(AU)

Animais silvestres podem ser reservatórios naturais de diferentes microrganismos, sendo fundamental o monitoramento destes patógenos para a geração de conhecimento e criação de ferramentas direcionadas a programas de prevenção e controle de enfermidades infecciosas, incluindo as zoonoses. Assim, objetivou-se relatar a diversidade fúngica da pele de pacas criadas em cativeiro no Acre, Amazônia Ocidental, Brasil. Foram avaliados 26 animais, dos quais amostras cutâneas foram colhidas por raspagem superficial, avulsão pilosa e escova plástica estéril. As amostras foram semeadas em ágar Mycosel e as características fenotípicas das colônias foram analisadas. Em 80,8% das amostras houve isolamento de diferentes fungos, dos gêneros Candida, Microsporum e Trichophyton, dentre outros. Esta é a primeira descrição da identificação de fungos na pele de pacas e sugere que estes animais podem ser considerados importantes reservatórios de microrganismos saprófitas ou patogênicos, de potencial zoonótico, na Amazônia Ocidental.(AU)

Edible flowers of Helichrysum italicum: Composition, nutritive value, and bioactivities.

Helichrysum italicum (H. italicum) is a halophyte shrub with bright yellow flowers with a strong curry-like aroma. The essential oils of H. italicum have been used in the production of cosmetics and pharmaceuticals, due to their antiallergic and anti-inflammatory properties. In the agri-food sector, H. italicum flowers can be used for seasoning and flavoring food, and as natural food preservatives. Here, we report on the composition, bioactive compounds, and nutritive value of H. italicum flowers. Flowers were mainly composed of carbohydrates (>80 % dry weight), followed by minerals (6.31 ± 0.95 % dw), protein (5.44 ± 0.35 % dw), and lipids (3.59 % ± 0.53 % dw). High percentages of Fe, Zn, Ca, and K were found in the flower material, along with a high content in antioxidants, polyphenols, and carotenoids, as corroborated by the nuclear magnetic resonance (NMR) data. Flowers were mainly composed of saturated fatty acids (SFAs) (54.50 ± 0.95 % of total FA), followed by polyunsaturated fatty acids (PUFAs) (37.73 ± 1.25 % of total FA) and monounsaturated fatty acids (MUFAs) (7.77 ± 0.34 %), as detected by gas chromatography mass spectrometry (GC-MS). The omega-6 PUFA linoleic acid (22.55 ± 0.76 % of total FA) was the most abundant fatty acid found. Flower extracts showed antimicrobial activity against Saccharomyces cerevisiae and Komagataella phaffii, as well as against Gram-negative (Klebsiella pneumoniae) and Gram-positive (Staphylococcus aureus) bacteria. H. italicum flower material was nontoxic to human intestinal Caco-2 model cells at concentrations up to 1.0 % w/v.

Wild capybaras as reservoir of shiga toxin-producing Escherichia coli in urban Amazonian Region.

Capybaras are rodent widely distributed in South America, which inhabit lakeside areas including ecological parks and urban sites. Due to anthropological interaction, monitoring zoonotic pathogens in wildlife is essential for One Health. We investigated faecal samples from capybaras living in an urban area in Rio Branco (Acre, Brazil) for the presence diarrhoeagenic E. coli. Virulence factors from shiga toxin-producing E. coli (STEC), enterohaemorrhagic E. coli (EHEC), and enteropathogenic E. coli (EPEC) were screened by PCR. We detected at least one virulence factor in 81% of the animals, being classified as STEC and EHEC pathotypes. The presence of zoonotic E. coli in capybaras is a warning due to the highly frequent anthropological interactions with wild animals in this area. Our findings highlight the importance of investigating wild animals as carriers of zoonotic E. coli, requiring further investigations into wildlife surveillance and epidemiological monitoring.

Corema album spp: Edible wild crowberries with a high content in minerals and organic acids.

Edible wild plants are part of the ethnobotanical and gastronomic heritage of different geographical areas. Corema album (L.) D. Don is an endemic species of the dune systems of the Atlantic coast of the Iberian Peninsula. The aerial parts of Corema album are a source of nutrients and antioxidants. The Corema album white berry (Portuguese crowberry) is rich in calcium, iron, and zinc. The plant also shows high phenolic content and antioxidant capacity associated with the leaves, fruit, and flowers. The presence of organic acids, namely phenolic acids, such as hydroxycinnamic acids, and long chain polyunsaturated fatty acids (PUFAs) omega-3 and omega-6 has also been confirmed. Toxicity studies evaluated by cell viability tests with human intestinal epithelium model cells (Caco-2) have shown that, at low concentrations, plant extracts may present beneficial effects.

Evaluation of rickettsial infection in free-range capybaras (Hydrochoerus hydrochaeris Linnaeus, 1766) (Rodentia: Caviidae) and ticks (Acari: Ixodidae) in the Western Amazon, Brazil.

Capybaras (Hydrochoerus hydrochaeris Linnaeus, 1766) (Rodentia: Caviidae) are important hosts of Amblyomma ticks (Acari: Ixodidae), which in turn can transmit rickettsiae to humans and animals. However, there is a scarcity of studies about the tick fauna and rickettsial infection in the Amazon region. The present study evaluated rickettsial infection in capybaras and ticks in different areas of the municipality of Rio Branco, state of Acre, in the Western Brazilian Amazon, where rickettsiosis has never been reported. Blood sera from 43 capybaras from four localities in Rio Branco were tested by indirect immunofluorescence assay using Rickettsia rickettsii antigens. Ticks were collected from capybaras and from vegetation as well. Ticks were taxonomically identified to the species level and some of them were tested by PCR, targeting a fragment of the rickettsial gltA gene. Additionally, ticks were tested for bacteria from the genus Borrelia and family Anaplasmatacae. All capybaras submitted to the serological examination were considered non-reactive to R. rickettsii. A total of 410 ticks were collected directly from the capybaras. Amblyomma dubitatum Neumann, 1899 was the most abundant species (82.4%), followed by Amblyomma naponense (Packard, 1869) (14.3%), Amblyomma humerale Koch, 1844 (0.7%), Amblyomma pacae Aragão, 1911 (0.4%), Amblyomma rotundatum Koch 1844 (0.2%) and Amblyomma sp. (1.7%). From the environment 262 ticks were collected: Rhipicephalus microplus (Canestrini, 1888) (88.9%), Dermacentor nitens Neumann, 1897 (9.9%), Amblyomma varium Koch, 1844 (0.7%) and A. rotundatum (0.3%). With the exception of A. humerale, A. rotundatum and R. microplus, all other species are reported here for the first time in the state. Some of the ticks sampled (N = 317) were tested by molecular methods for infection by Rickettsia spp. Rickettsia bellii was identified infecting A. dubitatum and A. rotundatum, while Rickettsia amblyommatis only was found infecting A. humerale and Rickettsia sp. strain Tapirapé was found in A. naponense. This is the first detection of R. bellii and Rickettsia sp. strain Tapirapé in Acre. No Borrelia or Anaplasmataceae were found in the tested ticks. These results add relevant knowledge about the Rickettsia spp. and the acarological fauna in the region of the Western Amazon, and are essential for the maintenance of vigilance about possible pathogens that occur in the state and determination of the risks that they pose to humans and animals that inhabit the region.

Myocardial dysfunction in Takotsubo syndrome: More than meets the eye?

INTRODUCTION: Takotsubo syndrome (TTS) is characterized by transient left ventricular (LV) dysfunction, typically mimicking an anterior wall myocardial infarction (MI), without obstructive coronary artery disease. In the few published reports assessing myocardial deformation in TTS and MI, no consistent differences have been described between the two entities. We sought to characterize global and regional function in TTS and to compare it with a population with MI. METHODS: Clinical data, including echocardiography, were gathered from 17 TTS patients and 20 anterior wall ST-segment elevation myocardial infarction (STEMI) controls. Peak systolic longitudinal strain was determined for each LV segment using speckle tracking imaging, and global and mean apical, midventricular and basal longitudinal strain were calculated from these. RESULTS: Both TTS and STEMI patients presented significant LV systolic dysfunction, and there were no significant differences in ejection fraction or global longitudinal strain. Regional longitudinal strain was more severely impaired in basal inferolateral and mid anterolateral segments in the TTS group and in apical anteroseptal segments in the STEMI group. Mean longitudinal strain was worse in the basal segments of TTS patients (-9.8±2.9 vs. -12.4±4.1%, p=0.010), with no significant differences in mid and apical segments. The basal/apical ratio was significantly lower in this group as well (1.51±0.86 vs. 2.94±1.88, p=0.006). CONCLUSIONS: While both TTS and STEMI feature significantly impaired global systolic function, we found a regional pattern of worse basal longitudinal strain and a lower basal/apical ratio in the former. These suggest generalized myocardial impairment in TTS, providing new clues about its pathophysiology and possible specific echocardiographic changes.

The urban and rural capybaras (Hydrochoerus hydrochaeris) as reservoir of Salmonella in the western Amazon, Brazil / As capivaras urbanas e rurais (Hydrochoerus hydrochaeris) como reservatório de Salmonella no oeste da Amazônia, Brasil

The capybara (Hydrochoerus hydrochaeris) is the largest rodent in the world. In the state of Acre, Brazil, populations of capybaras have been increasing significantly. The role of capybaras in the transmission of certain bacterial zoonotic infections is not well understood, including bacteria of the genus Salmonella. Salmonella spp. generally cause enteritis or septicemia in mammals, however many mammalian species can carry the bacteria asymptomatically and shed it in their feces. To better understand the possible role of capybaras as reservoirs of Salmonella spp., we conducted a study of Salmonella within fecal samples from capybara in Acre. In a convenience sample, 54 capybaras from two urban and two rural areas of Acre were captured and kept for three to four days for sampling. None of the animals were symptomatic of any intestinal illness. Three separate fecal samples were collected from each animal, during their stays in captivity. Each sample was cultured for the presence of Salmonella spp. at the bacteriology laboratory of the Veterinary College of the Federal University of Acre. Samples were seeded in tetrationate pre-enrichment broth and in pre-enrichment broth peptone. After a 24 hour of incubation all samples were streaked on MacConkey Agar (MC) and Salmonella-Shigella Agar (SS). Suggestive colonies were submitted to biochemical analysis. Salmonella compatible colonies according to biochemical profile were submitted to serotyping (Sorokit for Salmonella - Probac do Brasil). In addition, the first sample from each of the 54 capybara was tested for Salmonella spp. using PCR targeting gene hilA. Eight (5%) of the 162 samples examined by bacterial culture were positive for Salmonella spp., while four (7%) of the 54 examined by PCR were positive. From the eight positive animals on culture, five were from urban area and three from rural area. On PCR, only one positive animal was from urban area and four were from rural area. Overall, by either test, one of the 54 animals was positive. All samples were collected in free - living animals with no apparent clinical signs of salmonellosis, indicating the potential of capybara as reservoir on this ecosystem.(AU)

A capivara (Hydrochoerus hydrochaeris) é o maior roedor do mundo. No estado do Acre, Brasil, as populações de capivaras têm aumentado significativamente. O papel das capivaras na transmissão de certas infecções zoonóticas bacterianas não é bem compreendido, incluindo as bactérias do gênero Salmonella. Salmonella spp. geralmente causam enterite ou septicemia em mamíferos, porém muitas espécies de mamíferos podem carregar a bactéria de forma assintomática e eliminá-la em suas fezes. Para entender melhor o possível papel das capivaras como reservatórios de Salmonellaspp., realizamos um estudo para identificação de Salmonella spp. em amostras fecais de capivaras no Acre. Em uma amostra de conveniência, 54 capivaras de duas áreas urbanas e duas áreas rurais do Acre foram capturadas e mantidas por três a quatro dias para amostragem. Nenhum dos animais era sintomático de qualquer doença intestinal. Três amostras fecais foram coletadas de cada animal, durante sua permanência em cativeiro. Cada amostra foi cultivada para a presença de Salmonella spp. no Laboratório de Bacteriologia Veterinária da Universidade Federal do Acre. As amostras foram semeadas em caldo de pré-enriquecimento tetrationato e em peptona de caldo de pré-enriquecimento. Após 24 horas de incubação, todas as amostras foram semeadas em ágar MacConkey (MC) e ágar Salmonella-Shigella (SS). Colônias sugestivas foram submetidas a análises bioquímicas. Colônias compatíveis com Salmonella de acordo com o perfil bioquímico foram submetidas à sorotipagem (Sorokit para Salmonella - Probac do Brasil). Além disso, a primeira amostra de cada uma das 54 capivaras foi testada para Salmonella spp. usando PCR, visando gene hilA. Oito (5%) das 162 amostras examinadas por cultura bacteriana foram positivas para Salmonella spp. Enquanto quatro (7%) das 54 examinadas pela PCR foram positivas. Dos oito animais positivos em cultura, cinco eram de área urbana e três de área rural. Na PCR, apenas um animal positivo era de área urbana e quatro de área rural. Considerando o diagnóstico conjunto por ambos os testes, PCR e cultura, um animal foi considerado positivo. Todas as amostras foram coletadas em animais livres, sem sinais clínicos aparentes de salmonelose, indicando o potencial da capivara como reservatório nesse ecossistema.(AU)

Natural Trypanosoma (Trypanozoon) evansi (Steel, 1885) infection among mammals from Brazilian Amazon.

Trypanosoma evansi (Kinetoplastea Trypanosomatidae) is the Trypanosoma species that infects the greatest variety of mammals worldwide. In 2014, a dog from Rio Branco/AC, in the Brazilian Amazon region, presented flagellates without evident kinetoplasts in blood and symptoms of T. evansi infection. Our aim was to investigate the occurrence of T. evansi in dogs, bats and capybaras from Rio Branco. Blood was collected from 78 dogs from residential areas near the Zoobotanical Park (PZ). The serological diagnosis by IFAT detected the presence of anti-T. evansi antibodies in 21.9% of the evaluated dogs. T. evansi DNA was detected in one dog using a higly specific target of a repeated monomer of the satellite DNA of Trypanosoma (Trypanozoon) sp. Molecular diagnosis was also performed on 182 bat spleen samples collected inside PZ, and one Carollia perspicillata was positive. The DNA sequences obtained from these two samples showed similarities with T. brucei satellite DNA. Anti-T. evansi IFAT was carried out in 46 capybaras from rural and urban areas and the infection detected in 17.4% of them. We confirmed for the first time the presence of T. evansi in Acre State and describe three putative host species involved in the parasite transmission in that Amazon region. Moreover, this is the first study that confirms the infection by T. evansi through DNA sequence analysis in the Brazilian Amazon Region.

Aortic dilatation after tetralogy of Fallot repair: A ghost from the past or a problem in the future?

INTRODUCTION AND AIMS: Intrinsic aortopathy can lead to dilatation late after tetralogy of Fallot (TOF) repair. Its extent and prevalence are not known. We aimed to assess aortic dimensions and elasticity and to find predictors of aortic dilatation. METHODS: A total of 126 adults were prospectively included after TOF repair and compared to 63 gender- and age-matched controls. Transthoracic echocardiography was used to assess aortic diameters at the level of the sinuses of Valsalva and ascending aorta and aortic dilatation was defined as z-score >+2. M-mode parameters of the ascending aorta were used to calculate strain, distensibility and stiffness index. RESULTS: TOF patients (mean age 30±9 years; 52% male) had a complete repair at a median age of five (2-49) years; mean follow-up time since repair was 23±7 years. The prevalence of aortic dilatation at the sinuses of Valsalva and ascending aorta was 29% and 24%, respectively. Compared to controls, TOF patients had a higher ascending aorta z-score, lower strain (6.4% [0.0-61.5] vs. 15.2% [0.0-45.0], p<0.01) and higher stiffness index (7.3 [0.8-23.6] vs. 3.1 [0.9-14.1], p<0.01). On multivariate analysis male gender was strongly associated with sinuses of Valsalva dilatation (odds ratio 6.3, 95% confidence interval 1.5-26.3, p=0.01). CONCLUSIONS: The prevalence of aortic dilatation late after TOF repair is significant, with a larger and stiffer ascending aorta. Male gender appears to influence aortic root dilatation. This aortopathy requires careful follow-up in order to prevent future complications.

Percutaneous Closure of a Fistulous Giant Coronary Aneurysm.

Giant coronary artery aneurysms larger than 50 mm are rare and associated with important complications: namely, rupture. Its workup requires comprehensive imaging and standard treatment is surgical exclusion. We present a 60-year-old patient with previous ostium secundum atrial septal defect surgical closure diagnosed with a giant proximal right coronary artery aneurysm (70 x 62 mm) fistulizing into the right atrium. Percutaneous closure of its aortic origin with an atrial septal occluder was successfully performed, and thrombosis of the aneurysm confirmed on angiography and echocardiogram. This case depicts an innovative, minimally invasive approach to this worrisome entity.

High fat diet and high polyphenols beverages effects in enzymatic and non-enzymatic antioxidant activity / Efectos de dieta con alto contenido de grasa y bebidas ricas en polifenoles en la actividad antioxidante enzimática y no enzimática

Background: High fat diets have been implicated in the generation of reactive oxygen species (ROS). Polyphenols from grapes may reduce ROS and restore oxidative balance. The aim of this study is to investigate the antioxidant properties of high polyphenols beverages associated with a high fat diet in enzymatic and non-enzymatic antioxidant activity. Material and methods: Fifty female rats were divided into five groups: a) control group (CG) - control diet (4% fat); b) high fat diet group (HFD) - high fat diet (20% fat); c) grape juice group (GJ) - grape juice (15 ml/day) + high fat diet; d) red wine group (RW) - red wine (10 ml/day) + high fat diet; and e) resveratrol solution group (RS) - resveratrol solution (15 ml/day) + high fat diet. Eight weeks later, the superoxide dismutase, catalase and glutathione peroxidase activities were measured. Superoxide dismutase activity was assayed by measuring the inhibition of adrenaline auto-oxidation, catalase by the decrease rate in hydrogen peroxide and glutathione peroxidase by monitoring the oxidation of nicotinamide adenine dinucleotide phosphate. Non-enzymatic antioxidant activity was assessed by oxygen radical absorbance capacity and DDPH (free radical sequestration 2,2-diphenyl-1-picryhydracil) method in the animal’s plasma. Results: GC and GJ presented the lowest glutathione peroxidase activity, pointing to a possible protective effect of grape juice against high levels of ROS (p < 0.05). RW increased catalase activity when compared to the RS (p <0 .05). Superoxide dismutase activity and non-enzymatic antioxidant plasma activity were similar in all groups. Conclusion: Grape juice showed to be the most effective in minimizing the deleterious effects of a high fat diet. Resveratrol did not present any benefit and red wine possibly shows a harmful effect due to ethanol content (AU)

Introducción: las dietas ricas en grasas se han implicado en la generación de especies reactivas del oxigeno (ROS). Los polifenoles de las uvas pueden reducir el ROS y restaurar el equilibrio oxidativo. El objetivo de este estudio es investigar las propiedades antioxidantes de las bebidas ricas en polifenoles asociadas con una dieta rica en grasa en la actividad antioxidante enzimática y no enzimática. Material y métodos: cincuenta ratas fueron divididas en cinco grupos: a) grupo control (CG) - dieta de control (4% de grasa); b) grupo rica en grasa (HFD) - dieta con 20% de grasa; c) jugo de uva (GJ) - jugo (15 ml/día) + dieta rica en grasas; d) vino tinto (RW) - vino tinto (10 ml/día) + dieta rica en grasas; y e) grupo solución de resveratrol (RS) - solución de resveratrol (15 ml/día) + dieta rica en grasas. Se midieron superoxido dismutasa, catalasa y glutation peroxidasa. La actividad de superoxido dismutasa para la inhibición de la auto-oxidación de adrenalina, la catalasa por la tasa de disminución de peróxido de hidrogeno y glutation peroxidasa monitorizando la oxidación de nicotinamida adenina dinucleotido fosfato. La actividad antioxidante no enzimatica se midió por el método de capacidad de absorción de radicales de oxígeno y DDPH (moléculas estables de radicales libres 2,2-difenil-1-picrihidrazilo). Resultados: GC y GJ presentaron la menor actividad de glutation peroxidasa, señalando un posible efecto protector del jugo de uva frente a altos niveles de ROS (p < 0,05). RW aumento la actividad de catalasa en comparación con RS (p < 0,05). Superoxido dismutasa y la actividad antioxidante no enzimatica fueron similares. Conclusiones: el jugo demostró ser el más eficaz para minimizar los efectos deletereos de una dieta rica en grasas. Resveratrol no presento ningún beneficio y el vino tinto posiblemente muestra un efecto perjudicial debido al contenido de etanol (AU)

Should we continue to measure endometrial thickness in modern-day medicine? The effect on live birth rates and birth weight.

The evaluation of endometrial thickness (EMT) is still part of standard cycle monitoring during IVF, despite the lack of robust evidence of any value of this measurement to predict little revalidation in contemporary medical practice; other tools, however, such as endocrine profile monitoring, have become increasingly popular. The aim of this study was to reassess whether EMT affects the outcome of a fresh embryo transfer in modern-day medicine, using a retrospective, single-centre cohort of 3350 IVF cycles (2827 women) carried out between 2010 and 2014. In the multivariate regression analysis, EMT was non-linearly associated with live birth, with live birth rates being the lowest with an EMT less than 7.0 mm (21.6%; P < 0.001) and then between 7.0 mm and 9.0 mm (30.2%; P = 0.008). An EMT less than 7.0 mm was also associated with a decrease in neonatal birthweight z-scores (-0.40; 95% CI -0.69 to -0.12). In conclusion, these results reaffirm the use of EMT as a potential prognostic tool for live birth rates and neonatal birthweight in contemporary IVF, namely when considered together with other ovarian stimulation monitoring methods, such as the late-follicular endocrine profile.

Perfil epidemiológico das agressões caninas notificadas no Município de Cruzeiro do Sul, Acre, durante o período de 2007 a 2015 / Epidemiological profile of canine aggression reported in the City of Cruzeiro do Sul, Acre, from 2007 to 2015

A interação entre homens e animais tem consequências para a saúde pública, como o aumento dos casos de raiva, uma zoonose letal. Neste estudo, foram analisadas 1047 fichas do Sistema de Informação de Agravos de Notificação (SINAN). Os dados foram representativos do tratamento preventivo anti-raiva humano no município de Cruzeiro do Sul, Acre, de 2007 a 2015. O maior número de casos foi registrado em 2013 (17,95%) e a maior incidência de ataques ocorreu nas regiões urbanas (86,1%). As feridas resultantes de mordida de cão corresponderam a 98,66% dos ataques. Os animais foram classificados como suspeitos da raiva em 65,42% dos casos, no entanto, apenas 1% foram clinicamente diagnosticados como positivos. Apenas 4% das vítimas humanas foram submetidas a exame para pós-exposição de titulação. Os resultados indicam que os programas de Saúde Pública devem considerar como prioritários os ataques de cães na área urbana na cidade de Cruzeiro do Sul, Acre.

The interaction between men and animals results in consequences for public health, such as the increase of rabies cases, a lethal zoonosis. In this study, a total of 1047 file cards from the Brazilian Notification Aggravation Information System (Sistema de Informação de Agravos de Notificação - SINAN) were analyzed. The analyzed data was representative of human anti-rabies preventive treatment in the city of Cruzeiro do Sul, Acre, from 2007 to 2015. Most cases were registered in 2013 (17.95%). The highest incidence of attacks occurred in urban regions (86.1%). Wounds from dog bites corresponded to 98.66% of the attacks. The animals were classified as suspected rabies in 65.42% of cases. However, only 1% were clinically diagnosed as positive. Only 4% of the human victims were subjected to examination for post-exposure titration. The results indicate that Public Health programs should consider dog bite attacks in the urban area as a priority in in the city of Cruzeiro do Sul.

The role of capybaras as carriers of leptospires in periurban and rural areas in the western Amazon.

Although leptospirosis has been described in capybaras, usually based on serological evidences, bacterial culture of leptospires has been scarcely reported in this species. The western Amazon is a reportedly endemic area where high seroprevalences have been reported in different species of wildlife, domestic animals and in human beings. The present study aimed at investigating the role of capybaras as carriers of leptospires in periurban and rural areas in the western Amazon region. A total of 44 animals were captured, and 41 blood samples (for serology) and 41 urine samples (for PCR and bacterial culture) were obtained. A total of 18/41 (43.9%) of sera were reactive and titers were generally low, indicating chronic infection. PCR was positive in 13/41 (31.7%) samples, isolates were recovered from urine samples belonging to Icterohaemorrhagiae, Grippotyphosa and Shermani serogroups. A high number of carriers (confirmed by PCR) associated to a tendency for harboring Icterohaemorrhagiae serogroup strains could be noticed. Our results suggest that capybaras are massively infected by leptospires. Analogously to Norway rats, capybaras present chronic infection with low titers and long-term bacterial shedding, and may be acting as reservoirs of this bacterium.

High fat diet and high polyphenols beverages effects in enzymatic and non-enzymatic antioxidant activity.

BACKGROUND: High fat diets have been implicated in the generation of reactive oxygen species (ROS). Polyphenols from grapes may reduce ROS and restore oxidative balance.

Superoxide dismutase activity was assayed by measuring the inhibition of adrenaline auto-oxidation, catalase by the decrease rate in hydrogen peroxide and glutathione peroxidase by monitoring the oxidation of nicotinamide adenine dinucleotide phosphate. Non-enzymatic antioxidant activity was assessed by oxygen radical absorbance capacity and DDPH (free radical sequestration 2,2-diphenyl-1-picryhydracil) method in the animal's plasma. RESULTS: GC and GJ presented the lowest glutathione peroxidase activity, pointing to a possible protective effect of grape juice against high levels of ROS (p < 0.05). RW increased catalase activity when compared to the RS (p <0 .05). Superoxide dismutase activity and non-enzymatic antioxidant plasma activity were similar in all groups. CONCLUSION: Grape juice showed to be the most effective in minimizing the deleterious effects of a high fat diet. Resveratrol did not present any benefit and red wine possibly shows a harmful effect due to ethanol content.

Synchronization of estrus in paca (Cuniculus paca L. ): possible impacts on reproductive and productive parameters / Sincronização do estro em pacas (Cuniculus paca L. ): possíveis impactos sobre parâmetros reprodutivos e produtivos

Estrus synchronization is a reproductive biotechnology used to improve artificial insemination or pairing through the manipulation of the estrous cycle at a desirable time. Employing this technique in captive pacas (Cuniculus paca L.) is important because it creates expectation of meeting the demand for paca meat and, consequently, reduces poaching. Thus, this research aims to verify the effect of a progestogen implant associated with two doses of eCG on the synchronization and induction of fertile estrus. Twenty-seven adult pacas were used, 18 non-pregnant females and nine males, divided into three groups. G1 and G2 females groups (treatments) received 1.5 mg Norgestomet and were injected intramuscularly, seven days later, with 0.13 mg of prostaglandin. After 24 hours the implants were removed and the animals immediately received 25 IU and 50 IU of ECG intramuscularly, respectively. The mating of the three groups took place on the same days. G3 females' group (control) showed estrus on different days after D0. Females under treatment displayed estrus only after removing the implant (D8). G1, G2, and G3 pregnancy rates were 100%, 66%, and 50%, respectively. Regarding births per parturition, 100% of G1 and G3 produced one offspring, while 50% of G2 produced two. Progestogen in the form of subcutaneous implants was effective in mimicking the luteal phase of the estrous cycle. After removal, implants favored the occurrence of a fertile estrus. As a conclusion, further studies must be conducted in order to establish in-depth possible association between 50 IU of eCG, and the occurrence of twin pregnancies.(AU)

A sincronização é uma biotécnica reprodutiva que melhora a porcentagem de cobertura por meio da manipulação do ciclo estral. Empregar esta biotécnica em pacas de cativeiro (Cuniculus paca L.) é importante, pois cria-se a expectativa de que a demanda pela carne seja atendida e a caça ilegal diminua. O objetivo da pesquisa foi verificar o efeito de implantes de progestágenos associados a duas doses de gonadotrofina coriônica equina (eCG) na sincronização e indução de cios férteis de pacas. Foram utilizadas 18 fêmeas não prenhas e nove machos, divididos em três grupos. Fêmeas do G1 e G2 receberam implantes com 1,5mg de Norgestomet e, sete dias depois, 0,13mg de prostaglandina via intramuscular (IM). No dia 8 (D8), foram retirados os implantes e G1 e G2 receberam 25 UI e 50 UI de eCG, IM, respectivamente; G3 foi o controle. O pareamento nos três grupos aconteceu nos mesmos dias. As fêmeas do G3 apresentaram cio alguns dias após o dia zero (D0). Fêmeas que receberam tratamento apresentaram cio só após a retirada do implante no dia 8 (D8). As taxas de prenhez de G1, G2 e G3 atingiram 100%, 66% e 50%, respectivamente. Em relação a filhotes por parto, 100% do G1 e G3 produziram uma cria, enquanto 50% do G2 produziram duas crias. O progestágeno do implante foi eficaz em mimetizar a fase lútea do ciclo estral. Após a remoção, o tratamento hormonal favoreceu a ocorrência de cio fértil. Outros estudos devem ser realizados a fim de estabelecer uma possível associação entre 50 UI de eCG e a ocorrência de gestações gemelares.(AU)
