Cães em situação de rua no município de Descalvado-SP: Uma análise visual e quantitativa / Street dogs in the municipality of Descalvado-SP: A visual and quantitative analysis

Alicerçado na necessidade de estabelecer políticas de bem-estar animal e promoção da saúde pública pela importância dos animais errantes na transmissão de zoonoses, objetivou-se estudar a dinâmica populacional de cães em situação de rua no município de Descalvado -SP, a percepção dos munícipes relacionada com a causa de proteção animal e também da legislação vigente Federal, Estadual e Municipal. Para contabilizar a separação dos setores urbanos e rurais, foi utilizada a ferramenta Clip do programa Qgis, setorizando o município de Descalvado em zona Norte, Sul, Leste, Oeste, Central e Distrito Industrial. Para a aplicação dos questionários foi selecionado 0,5% da população de cada zona estabelecida do município e os achados foram correlacionados a legislação e as políticas públicas existentes, analisando a eficácia das mesmas. Como podemos notar, de maneira resumida, os entrevistados cobram do poder público local por melhorias, mas também, maior responsabilidade da população. Além da análise qualitativa através da leitura e percepção dos relatos, foi realizado uma análise da repetição de palavras chave, através da confecção da nuvem de palavras, importante ferramenta que destaca os termos mais citados pelas pessoas entrevistadas, das quais se destaca "fiscalização, leis e conscientização", revelando a necessidade dos direcionamentos das políticas públicas. Os dados nos levam a concluir que apesar da existência de legislação, ainda há pouca aplicação de penalidades. No município, as zonas com maiores índices de cães em situação de rua foram Oeste e Sul, regiões periféricas e com população de baixa renda.(AU)

Based on the need to establish animal welfare policies and public health promotion due to the importance of stray animals in the transmission of zoonoses, the objective was to study the population dynamics of homeless dogs in the city of Descalvado -SP, the perception of citizens related to the cause of animal protection and also to the current Federal, State and Municipal legislation. To account for the separation of urban and rural sectors, the Clip tool of the Qgis program was used, sectoring the municipality of Descalvado into North, South, East, West, Central and Industrial District. For the application of the questionnaires, 0.5% of the population from each established area of the municipality was selected and the findings were correlated with existing legislation and public policies, analyzing their effectiveness. As we can see, in summary, the interviewees demand from the local government for improvements, but also, greater responsibility of the population. In addition to the qualitative analysis through the reading and perception of the reports, an analysis of the repetition of key words was carried out, through the creation of the word cloud, an important tool that highlights the terms most cited by the people interviewed, of which "oversight, laws and awareness", revealing theneed for public policy directions. The data lead us to conclude that despite the existence of legislation, there is still little application of penalties. In the city, the areas with the highest rate of stray dogs were West and South, peripheral regions and with low-income population.(AU)

Positive selection over the mitochondrial genome and its role in the diversification of gentoo penguins in response to adaptation in isolation.

Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong influence on mitochondrial genomes, to the point of promoting the persistence of certain genotypes in order to compensate for the metabolic requirements of the local environment. As recently discovered, the gentoo penguins (Pygoscelis papua) comprise four highly divergent lineages across their distribution spanning the Antarctic and sub-Antarctic regions. Gentoo penguins therefore represent a suitable animal model to study adaptive processes across divergent environments. Based on 62 mitogenomes that we obtained from nine locations spanning all four gentoo penguin lineages, we demonstrated lineage-specific nucleotide substitutions for various genes, but only lineage-specific amino acid replacements for the ND1 and ND5 protein-coding genes. Purifying selection (dN/dS < 1) is the main driving force in the protein-coding genes that shape the diversity of mitogenomes in gentoo penguins. Positive selection (dN/dS > 1) was mostly present in codons of the Complex I (NADH genes), supported by two different codon-based methods at the ND1 and ND4 in the most divergent lineages, the eastern gentoo penguin from Crozet and Marion Islands and the southern gentoo penguin from Antarctica respectively. Additionally, ND5 and ATP6 were under selection in the branches of the phylogeny involving all gentoo penguins except the eastern lineage. Our study suggests that local adaptation of gentoo penguins has emerged as a response to environmental variability promoting the fixation of mitochondrial haplotypes in a non-random manner. Mitogenome adaptation is thus likely to have been associated with gentoo penguin diversification across the Southern Ocean and to have promoted their survival in extreme environments such as Antarctica. Such selective processes on the mitochondrial genome may also be responsible for the discordance detected between nuclear- and mitochondrial-based phylogenies of gentoo penguin lineages.

New ethionamide boosters and EthR2: structural and energetic analysis.

Ethionamide (ETH) is a high-profile drug for the treatment of patients with multidrug-resistant Mycobacterium tuberculosis and, in order to produce its inhibitory effects, it needs to be bioactivated by monooxygenase EthA. This process is under the control of the transcriptional repressors EthR and EthR2, so that their inhibition results in the boosting of ethionamide activation. Herein, through crystallographic data and computer simulations, we calculated the interaction binding energies of four inhibitors with improved in vitro potency, namely BDM76060 (PDB ID: 6HS1), BDM72201 (PDB ID: 6HRX), BDM76150 (PDB ID: 6HS2) and BDM72719 (PDB ID: 6HRY), in complexes with the transcriptional repressor EthR2, using density functional theory (DFT) within the molecular fractionation with conjugated caps (MFCC) approach. It was observed that these ligands share the same binding site within a 10.0 Å radius of the EthR2 protein; however, their structural particularities have a significant impact on the global energies of systems. The BDM72201 and BDM72719 components are weakly attached to the binding site, while BDM76060 and BDM76150 components produce stronger bonds, corroborating with experimental studies demonstrating that BDM76060 and BDM76150 are more successful in producing inhibitory effects. BDM76060 and BDM76150 have many functional groups that increase the contact surface with the protein and attract a more significant number of amino acid residues, being able to produce polarities that generate stronger interactions. In the current scenario of a growing number of cases of bacterial resistance, the obtained data can be used to guide clinical trials of these inhibitors and other inhibitors that act on the alternative EthR2 pathway, focusing on improving the activity of ethionamide, its effectiveness, a reduction in the treatment time and exposure to cytotoxic effects.

Contrasting phylogeographic pattern among Eudyptes penguins around the Southern Ocean.

Since at least the middle-Miocene, the Antarctic Polar Front (APF) and the Subtropical Front (STF) appear to have been the main drivers of diversification of marine biota in the Southern Ocean. However, highly migratory marine birds and mammals challenge this paradigm and the importance of oceanographic barriers. Eudyptes penguins range from the Antarctic Peninsula to subantarctic islands and some of the southernmost subtropical islands. Because of recent diversification, the number of species remains uncertain. Here we analyze two mtDNA (HVRI, COI) and two nuclear (ODC, AK1) markers from 13 locations of five putative Eudyptes species: rockhopper (E. filholi, E. chrysocome, and E. moseleyi), macaroni (E. chrysolophus) and royal penguins (E. schlegeli). Our results show a strong phylogeographic structure among rockhopper penguins from South America, subantarctic and subtropical islands supporting the recognition of three separated species of rockhopper penguins. Although genetic divergence was neither observed among macaroni penguins from the Antarctic Peninsula and sub-Antarctic islands nor between macaroni and royal penguins, population genetic analyses revealed population genetic structure in both cases. We suggest that the APF and STF can act as barriers for these species. While the geographic distance between colonies might play a role, their impact/incidence on gene flow may vary between species and colonies.

Comparative phylogeography of co-distributed Phrygilus species (Aves, Thraupidae) from the Central Andes.

The Neotropical ecoregion has been an important place of avian diversification where dispersal and allopatric events coupled with periods of active orogeny and climate change (Late Pliocene-Pleistocene) have shaped the biogeography of the region. In the Neotropics, avian population structure has been sculpted not only by geographical barriers, but also by non-allopatric factors such as natural selection and local adaptation. We analyzed the genetic variation of six co-distributed Phrygilus species from the Central Andes, based on mitochondrial and nuclear markers in conjunction with morphological differentiation. We examined if Phrygilus species share patterns of population structure and historical demography, and reviewed the intraspecific taxonomy in part of their geographic range. Our results showed different phylogeographic patterns between species, even among those belonging to the same phylogenetic clade. P. alaudinus, P. atriceps, and P. unicolor showed genetic differentiation mediated by allopatric mechanisms in response to specific geographic barriers; P. gayi showed sympatric lineages in northern Chile, while P. plebejus and P. fruticeti showed a single genetic group. We found no relationship between geographic range size and genetic structure. Additionally, a signature of expansion was found in three species related to the expansion of paleolakes in the Altiplano region and the drying phase of the Atacama Desert. Morphological analysis showed congruence with molecular data and intraspecific taxonomy in most species. While we detected genetic and phenotypic patterns that could be related to natural selection and local adaptation, our results indicate that allopatric events acted as a major factor in the population differentiation of Phrygilus species.

Cross-amplification of nonspecific microsatellites markers: a useful tool to study endangered/vulnerable species of southern Andes deer.

Thirty-nine microsatellite loci that are highly conserved in red deer, sika deer, reindeer, Soay sheep, and other artiodactyls were tested in two vulnerable and endangered Neotropical deer (pudu: Pudu puda and huemul: Hippocamelus bisulcus) with the aim of producing a standardized set of markers that can be used successfully in noninvasive samples from these species. We also compared these nonspecific loci against eight polymorphic loci that were recently developed for huemul to determine whether the nonspecific markers could reflect the huemul's genetic variation that was observed with the specific loci. We identified 10 suitable loci, six of which constitute a standardized set for the two species and can be used to identify them in the absence of phenotypic data. The expected heterozygosity per locus for the panel of six loci ranged from 0.461 to 0.889 (average 0.665), and the maximum probability of identity value was 6.9x10(-6) and 3.2x10(-4) in pudu and huemul, respectively. This set of loci has potential applications in evolutionary, ecological, forensic, and conservation studies in pudu and huemul.

Treatment of early rheumatoid arthritis in a multinational inception cohort of Latin American patients: the GLADAR experience.

BACKGROUND: Treatment of rheumatoid arthritis (RA) has evolved dramatically in the last decade. However, little is known about the way rheumatologists in Latin America treat their patients in clinical practice, outside the scope of clinical trials. OBJECTIVE: The objective of this study was to describe treatment patterns at disease onset in early RA with data from a large, multicenter, multinational inception cohort of Latin American patients. METHODS: Consecutive patients with early RA (<1 year of disease duration as diagnosed by a rheumatologist) from 46 centers in 14 Latin American countries were enrolled in the study. Clinical data, laboratory assessments, and a detailed registry on type of prescriptions were collected at baseline and at 3, 6, 12, 18, and 24 months of follow-up. Hands and feet x-rays were obtained at baseline and at 12 and 24 months. All data were captured in Arthros 6.1 database. Continuous variables were expressed as means and SDs, and categorical variables were expressed as percentages and 95% confidence intervals (95% CIs). Only therapeutic data at baseline are presented, corresponding to the period between disease onset and second visit (3 months). RESULTS: A total of 1093 patients were included. Eighty-five percent were female, and 76% had a positive rheumatoid factor. Mean age at diagnosis was 46.5 (SD, 14.2) years, and mean disease duration at the first visit was 5.8 (SD, 3.8) months. Between baseline and second visit (3 months), 75% of patients (95% CI, 72%-78%) received disease-modifying antirheumatic drugs. Methotrexate (MTX) alone or in combination was the most frequently used (60.5%), followed by antimalarials (chloroquine or hydroxychloroquine, 32.1%), sulfasalazine (7.1%), and leflunomide (LEF, 4%). In 474 patients (43%), initiation of disease-modifying antirheumatic drugs was within the first month after the first visit. In addition, 290 patients (26%; 95% CI, 23%-29%) received combination therapy as initial treatment. The most frequently used combinations were MTX + chloroquine (45%), MTX + hydroxychloroquine (25%), and MTX + sulfasalazine (16%). Eleven patients (1%; 95% CI, 0.5%-1.8%) received biologics. Sixty-four percent (95% CI, 60%-66%) received corticosteroids. Of those, 80% (95% CI, 77%-84%) received 10 mg of oral prednisone or less. CONCLUSIONS: In this cohort of Latin American patients with early RA, most patients received MTX very early in their disease course. Combination therapy was used approximately in 1 of every 4 patients as initial therapy. Biologics were rarely used at this early stage, and low-dose prednisone was commonly used.

Time variation of some selected topics in bioethical publications.

OBJECTIVE: To analyse the time variation of topics in bioethical publications as a proxy of the relative importance. METHODS: We searched the Medline database for bioethics publications using the words "ethics or bioethics", and for 360 specific topics publications, associating Medical Subject Heading topic descriptors to those words. We calculated the ratio of bioethics publications to the total publications of Medline, and the ratio of each topic publications to the total bioethics publications, for five-year intervals, from 1970 to 2004. We calculated the time variation of ratios, dividing the difference between the highest and lowest ratio of each topic by its highest ratio. Four topics were described, selected to illustrate different patterns of variation: "Induced Abortion", "Conflict of Interest", "Acquired Immunodeficiency Syndrome", "Medical Education." RESULTS: The ratio of bioethics publications to total Medline publications increased from 0.003 to 0.012. The variation of the topic's ratios was higher than 0.7 for 68% of the topics. The Induced Abortion ratios decreased from 0.12 to 0.02. Conflict of Interest ratios increased from zero to 0.07. The Acquired Immunodeficiency Syndrome ratios were nearly zero in the first three intervals, had a peak of 0.06 during 1985-9, followed by a decrease to 0.01. Medical Education ratios varied few, from 0.04 to 0.03. CONCLUSIONS: There was an increase of bioethical publications in the Medline database. The topics in bioethics literature have an important time variation. Some factors were suggested to explain this variation: current legal cases, resolution of the issue, saturation of a discussion and epidemiologic importance.

Redução da variabilidade da freqüência cardíaca em indivíduos de meia-idade e o efeito do treinamento de força / Reduction of heart rate variability in middle-aged individuals and the effect of strength training

OBJETIVO: Investigar a modulação autonômica exercida sobre o nodo sinusal, por meio da análise da variabilidade da freqüência cardíaca (VFC), em indivíduos jovens e de meia-idade (MI), bem como os efeitos de um programa de treinamento de força resistência sobre tal modulação nos indivíduos de meia-idade. MÉTODO: Trinta e dois homens sadios, sedentários e não-tabagistas, sendo 10 jovens (22,2 ± 1,5 anos) e 22 de MI (49,3 ± 5,3 anos), foram submetidos à aquisição do sinal de eletrocardiograma para análise da VFC no domínio do tempo. Os indivíduos de MI foram divididos em dois grupos: experimental (n= 12) e controle (n= 10). Os indivíduos do grupo experimental foram inseridos em um programa de treinamento de força com duração de três meses. A análise dos dados foi realizada por meio dos testes de Wilcoxon e Mann-Whitney (p< 0,05). RESULTADOS: O grupo MI apresentou redução significativa, em comparação ao jovem, de todas as variáveis utilizadas para a investigação da VFC (SDNN= 33,4 vs. 49,7ms; RMSSD= 29,9 vs. 49,5ms; pNN50= 6,5 vs. 27 por cento). O treinamento promoveu aumento significativo da força e resistência muscular em todos os grupamentos musculares e aumento não significativo das variáveis SDNN (33,4 vs. 37,6ms), RMSSD (30,2 vs. 31,3ms) e pNN50 (7,5 vs. 11,4 por cento). CONCLUSÕES: Os achados deste estudo confirmam que o aumento da idade provoca alteração na modulação autonômica exercida sobre o nodo sinusal, retratada por uma diminuição da VFC em indivíduos de MI, que não foi modificada de maneira significativa pelo tipo de treinamento físico estudado.

OBJECTIVE: To investigate autonomic modulation of the sinus node, by analyzing heart rate variability (HRV) among young and middle-aged individuals, and to assess the effect of an endurance strength training program on this modulation among middle-aged individuals. METHOD: Thirty-two healthy nonsmoking men with sedentary lifestyles, of whom 10 were young (22.2 ± 1.5 years) and 22 were middle-aged (49.3 ± 5.3 years), underwent electrocardiogram signal acquisition for time-domain HRV analysis. The middle-aged individuals were divided into two groups: experimental (n= 12) and control (n= 10). The individuals in the experimental group were enrolled in a strength training program lasting three months. The data analysis was carried out using the Wilcoxon and Mann-Whitney tests (p< 0.05). RESULTS: The middle-aged group presented significant reductions (in relation to the young group) for all the variables used in investigating HRV (SDNN= 33.4 vs. 49.7 ms; RMSSD= 29.9 vs. 49.5 ms; pNN50= 6.5 vs. 27 percent). The training caused a significant increase in muscle strength and endurance for all muscular groups and non-significant increases in the variables SDNN (33.4 vs. 37.6 ms), RMSSD (30.2 vs. 31.3 ms) and pNN50 (7.5 vs. 11.4 percent). CONCLUSIONS: The findings from this study confirm that increased age causes alteration to the autonomic modulation of the sinus node, as demonstrated by reduced HRV in middle-aged individuals, which was not significantly modified by the type of physical training studied.

The oral glucose tolerance test is frequently abnormal in patients with uncontrolled epilepsy.

PURPOSE: The clinical efficacy of the ketogenic diet as therapy for patients with difficult-to-treat epilepsy prompted us to investigate the glucose metabolism of these patients under an oral overload of glucose, that is, in the oral glucose tolerance test (OGTT). METHODS: Thirty patients (12 males, 18 females; age range: 17-59, mean: 35.1) with difficult-to-treat epilepsy, 23 patients with controlled epilepsy (11 males, 12 females; age range: 14-66, mean: 36.9), and 39 control subjects (18 males, 21 females; age range: 16-58, mean: 33.3) were evaluated with the OGTT. For patients with epilepsy, we also measured C-peptide and glycosylated hemoglobin in the fasting state. Glucose levels lower than 70 mg/dL at any point of the curve were considered to be abnormal. RESULTS: All subjects in the control group and the group with controlled epilepsy had a normal OGTT. In contrast, all 30 patients with difficult-to-treat epilepsy had at least one point on the OGTT curve below the normal range (P<0.001), most often 180 and 240 minutes after the oral glucose load (P<0.001). C-peptide levels were significantly lower in the group with difficult-to-treat epilepsy as compared with the group with controlled epilepsy. Fasting glycohemoglobin and insulin levels did not differ between the two patient groups. CONCLUSIONS: We suggest that undiagnosed metabolic disturbances in patients with difficult-to-treat epilepsy may somehow contribute to their refractoriness to conventional pharmacological therapy. We propose the hypothesis that calorie-restricted diets aimed at correcting OGTT curves may prove beneficial in treating patients with difficult-to-treat epilepsy. Our hypothesis generates a clear endpoint for the diet, and its demonstration would provide new standards for diet-based antiepileptic regimens. Accordingly, our results may help in understanding the positive consequences of ketogenic or calorie-restricted diets in persons with seizures.

Elimination of biliary stones through the urinary tract: a complication of the laparoscopic cholecystectomy.

The introduction and popularization of laparoscopic cholecystectomy has been accompanied with a considerable increase in perforation of gallbladder during this procedure (10% - 32%), with the occurrence of intraperitoneal bile spillage and the consequent increase in the incidence of lost gallstones (0.2% - 20%). Recently the complications associated with these stones have been documented in the literature. We report a rare complication occurring in an 81-year-old woman who underwent laparoscopic cholecystectomy and developed cutaneous fistula to the umbilicus and elimination of biliary stones through the urinary tract. During the cholecystectomy, the gall bladder was perforated, and bile and gallstones were spilled into the peritoneal cavity. Two months after the initial procedure there was exteriorization of fistula through the umbilicus, with intermittent elimination of biliary stones. After eleven months, acute urinary retention occurred due to biliary stones in the bladder, which were removed by cystoscopy. We conclude that efforts should be concentrated on avoiding the spillage of stones during the surgery, and that no rules exist for indicating a laparotomy simply to retrieve these lost gallstones.
