Bryophytes from Pocone county, Pantanal of Mato Grosso, Brazil

Sofrendo influências de outros ecossistemas, tais como o Cerrado e a Floresta Amazônica, o Pantanal de Mato Grosso constitui um ecossistema único. Embora sua flora fanerogâmica seja relativamente bem conhecida, a brioflora ainda necessita ser estudada mais profundamente. Fazendo parte da bacia do bio Paraguai e localizado a 94,8km de Cuiabá nas coordenadas 16º15'24"S e 56º36'24"W, o Município de Poconé possui uma população de cerca de 30.000 habitantes. Foram realizadas coletas briológicas nos anos de 1984, 1999 e 2000, tendo sido encontradas 12 espécies pertencentes a 12 famílias de Bryophyta e 10 espécies distribuídas em duas famílias de Marchantiophyta, sendo Lejeuneaceae a melhor representada, com oito espécies. Foram encontradas cinco novas ocorrências para o região Centro-Oeste: Trichosteleum fluviale (Mitt.) Jaeg., Frullania tetraptera Nees & Mont., Lejeunea glauscescens Gottsche, Lejeunea calcicola Schuster, Lejeunea caespitosa Lindenb. São ainda citadas nove novas ocorrências para o Estado do Mato Grosso: Hyophila involuta (Hook.) A. Jaeg., Groutiella apiculata (Hook.) Crum & Steere, Fabronia macroblepharis Schwaegr., Trichosteleum fluviale (Mitt.) Jaeg., Frullania arecae (Spreng.) Gottsche, Frullania tetraptera Nees & Mont., Lejeunea glauscencens Gottshe, Lejeunea calcicola Schuster e Lejeunea caespitosa Lindenb. Lejeunea calcicola Schuster é citada pela segunda vez para o Brasil.Under the influence of outer ecosystems, such as the Cerrado and Amazon rain forest, the Pantanal of Mato Grosso is a unique ecosystem. Otherwise his fanerogamic flora is well known, the bryoflora is yet to be properly discovered. As part of Paraguai river basin and located at 94.8km from Cuiabá at 16º15'24"S and 56º36'24"W, the county of Poconé has a population around 30,000 hab. Colects were taken in 1984, 1999 and 2000. Among the Division Bryophyte 12 species in 12 familie were founs. In the Division Marchantiophyta 10 species in two families were found. The better represented family was Lejeuneaceae, with eight species. Five new occurrences to the Centro-Oeste region were found: Trichosteleum fluviale (Mitt.) Jaeg., Frullania arecae (Spreng.) Gottsche, Frullania tetraptera Nees & Mont., Lejeunea glaucescens Gottsche, Lejeunea calcicola Schuster, Lejeunea caespitosa Lindenb. and nine new occurrences to Mato Grosso State were found: Hyophila involuta (Hook.) A. Jaeg., Groutiella apiculata (Hook.) Crum & Steere, Fabronia macroblepharis Schwaegr., Trichosteleum fluviale (Mitt.) Jaeg., Frullania tetraptera Nees & Mont., Lejeunea glaucescens Gottshe, Lejeunea calcicola Schuster and Lejeunea caespitosa Lindenb. Lejeunea calcicola Schuster is mentioned for the second time to Brazil

Briófitos de Cáceres, Pantanal de Matogrosso, Brasil, con nuevos registros para el estado y el país

The Pantanal Ecosystem is still poorly known in its bryoflora, with almost no literature and very few collections. This paper represents a contribution to better understand the bryophyte diversity in the brazilian Pantanal. With a population around 85,857 and 27,462.38 Km2 and located at 16º11’42" S and 57º40’51" W, the Cáceres county is totally inserted in the Pantanal ecosystem. Its bryoflora has never been studied before. Here are presented 5 liverworts and 21 mosses, of which Barbula indica (Hook.) Spreng., Calymperes palisoti Schwägr., Fabronia ciliaris var polycarpa (Hook) W.R.Buck, Taxiphyllum taxirameum (Mitt.) M. Fleisch. are cited for the first time for Mato Grosso. Fissidens dissitifolius Sull. is cited for the first time to Brazil and Tortella lilliputana (Müll. Hal. ex G. Roth) R.H. Zander, is cited for the second time to Brazil. The data suggest how poorly known the area still remains and more studies are in need for the Pantanal and Mato Grosso state.O ecossistema Pantanal ainda permanece pouco conhecido do ponto de vista briológico, com poucas coleções e quase nenhuma literatura. Neste contexto, este trabalho apresenta uma inédita contribuição para o conhecimento da diversidade briológica Pantaneira. Com uma população de 85.857 habitantes em 27.462,38 quilômetros quadrados, entre as coordenadas 16º11’42" S e 57º40’51" W, o municípo de Cáceres, está totalmente inserido no ecossistema Pantanal. Sua brioflora nunca foi estudada anteriormente. Neste trabalho apresentamos a ocorrência de 5 hepáticas e 21 musgos, entre os quais: Barbula indica (Hook.) Spreng., Calymperes palisoti Schwägr., Fabronia ciliaris var polycarpa (Hook) W.R.Buck, Taxiphyllum taxirameum (Mitt.) M. Fleisch. e Tortella lilliputana (Müll. Hal. ex G. Roth) R.H. Zander, são citadas pela primeira vez para o estado do Mato Grosso. Fissidens dissitifolius Sull. está sendo citado pela primeira vez para o Brasil e Tortella lilliputana (Müll. Hal. ex G. Roth) R.H. Zander é citada pela segunda vez. Os dados sugerem o quão pouco conhecida é a brioflora do ecossistema Pantanal e do Estado do Mato Grosso, sendo necessárias mais coletas e estudos na região

Polychaete research in Brazil: a bibliometric analysis

This article shows a comprehensive bibliometric analysis of the literature on polychaetes from Brazil, with a focus onthe growth of the field, publication venues, citation patterns, the collaboration among the Brazilian community andforeign researchers, and the main research topics over time. The analysis was based on a corpus of 568 articlespublished in 144 journals, covering a period from 1966 to 2022. The results reveal significant growth in the field,with a surge in publications particularly in the last decade. The top journals for publishing include Zootaxa, JMBA,and Zoologia. However, despite this growth, the overall impact of the research output remains somewhat limited,with most articles receiving relatively low numbers of citations, and those with more citations have broader researchquestions. This research community directed its efforts especially to taxonomy and phylogenetics research,community ecology, and physiology (ecotoxicology). These topics formed a common ground for more specializedthemes. International collaboration was driven by research specialization, better infrastructure, and fundingof developed countries. However, seeking collaborations with countries from the global south can also enrich theresearch conducted by the Brazilian community and stimulate new scientific inquiries. Embracing greater creativityand audacity as well as pursuing common goals, should yet enhance the quality of scientific research and sustainthe remarkable growth and consolidation of this renowned research communit

Avaliação prospectiva do laser de diodo micropulsado em pacientes com glaucoma refratário: resultados de um ano de seguimento

To evaluate the effectiveness in intraocular pressure reduction and safety of micropulse transscleral diode cyclophotocoagulation in refractory glaucoma. Methods: We prospectively evaluated a case series of 21 eyes of 21 consecutive patients with refractory glaucoma treated with micropulse transscleral diode cyclophotocoagulation at 12-month follow-up. The total treatment time was at the discretion of the surgeon, considering baseline and target intraocular pressure and glaucoma diagnosis. Intraocular pressure, inflammation, visual acuity, and number of medications were monitored. Success was defined as intraocular pressure between 6 and 21 mmHg and/or 30% reduction from baseline intraocular pressure with or without the use of antiglaucoma medications. Visual acuity loss was defined as a loss of >= 2 lines of vision on the Snellen chart or a >= 2-level decrease in visual function in patients with nonmeasurable chart acuity. Results: The mean age was 61.04 +/- 12.99 years, and 11 (52.4%) patients were male, with most (95%) patients showing low visual acuity at baseline (count fingers or worse). The mean intraocular pressure was 33.38 +/- 15.95 mmHg, and the mean number of medications was 3.5 +/- 1.1 at baseline. After 1, 3, 6, and 12 months, 76.19%, 57.14%, 55.56%, and 66.67%, respectively, of the patients were classified as treatment successes. Seven (33.3%) patients required new laser treatment and were considered treatment failures. The mean intraocular pressure reduction was 44.72% +/- 29.72% in the first week and 41.59% +/- 18.93% at the end of follow-up (p=0.006). The mean number of medications significantly dropped to 2.00 +/- 1.7 at the 12-month visit (p=0.044). Complications included hypotony (4.8%), intraocular inflammation after 1 month (19%), and visual acuity loss (4.8%). Conclusions: Micropulse transscleral diode cyclophotocoagulation was safe and effective for reducing intraocular pressure in eyes with refractory and advanced glaucoma, with reduced need for ocular antihypertensive medication825381388Avaliar a eficácia na redução da pressão intraocular e na segurança da ciclofotocoagulação com laser de diodo transescleral em glaucoma refratário. Métodos: Avaliamos prospectivamente uma série de casos de 21 olhos de 21 pacientes com glaucoma refratário tratados com ciclofotocoagulação com laser de diodo transescleral com acompanhamento por 12 meses. O tempo total de tratamento ficou a critério do cirurgião, considerando a pressão intraocular inicial e alvo e o tipo de glaucoma. Pressão intraocular, inflamação, acuidade visual e número de medicamentos foram monitorados. O sucesso foi definido como pressão intraocular entre 6 e 21 mmHg e/ou redução de 30% da pressão intraocular basal com ou sem o uso de medicamentos glaucomatosos. Perda da acuidade visual foi definida como perda de ≥2 linhas de visão na tabela de Snellen ou uma diminuição de ≥ 2 níveis na função visual em pacientes com acuidade do gráfico não mensurável. Resultados: A idade média foi de 61,04 ± 12,99 anos e 11 (52,4%) pacientes eram do sexo masculino, com a maioria (95%) dos pacientes apresentando baixa acuidade visual inicialmente (conta dedos ou pior). A pressão intraocular média foi de 33,38 ± 15,95 mmHg, e o número médio de medicamentos foi de 3,5 ± 1,1, no início do estudo. Após 1, 3, 6 e 12 meses, 76,19%, 57,14%, 55,56% e 66,67%, respectivamente, dos pacientes foram classificados como sucesso do tratamento. Sete (33,3%) pacientes necessitaram de novo tratamento com laser e foram considerados falhas no tratamento. A redução média da pressão intraocular foi de 44,72% ± 29,72% na primeira semana e 41,59% ± 18,93% no final do seguimento (p=0,006). O número médio de medicamentos diminuiu significativamente para 2,00 ± 1,7 na visita de 12 meses (p=0,044). As complicações incluíram hipotonia (4,8%), inflamação intraocular após 1 mês (19%) e perda de acuidade visual (4,8%). Conclusões: A ciclofotocoagulação com laser de diodo transescleral foi segura e eficaz para reduzir a pressão intraocular em olhos com glaucoma refratário e avançado, com necessidade reduzida de hipotensores oculare

Patient education in glaucoma: what do patients know about glaucoma?

PURPOSE: To evaluate the knowledge glaucoma patients have about their disease and its treatment. METHODS: One hundred and eighty-three patients were interviewed at the Glaucoma Service of Wills Eye Hospital (Philadelphia, USA, Group 1) and 100 at the Glaucoma Service of University of Campinas (Campinas, Brazil, Group 2). An informal, relaxed atmosphere was created by the interviewer before asking a list of 18 open-ended questions. RESULTS: In Group 1, 44% of the 183 patients did not have an acceptable idea about what glaucoma is, 30% did not know the purpose of the medications they were taking, 47% were not aware of what was an average intraocular pressure, and 45% did not understand why visual fields were examined. In Group 2, 54% gave unsatisfactory answers to the question What is glaucoma? , 54% did not know the purpose of the medications they were taking, 80% were not aware of what was an average intraocular pressure, and 94% did not understand why visual fields were examined (p\u3c0.001). Linear regression analysis demonstrated that level of education was positively correlated to knowledge about glaucoma in both groups (r=0.65, p=0.001). CONCLUSION: This study showed that patients\u27 knowledge about glaucoma varies greatly, and that in an urban, American setting, around one third of the patients have minimal understanding, whereas in an urban setting in Brazil around two thirds of patients were lacking basic information about glaucoma. Innovative and effective methods are needed to correct this situation

Reprodutibilidade do teste de sobrecarga hídrica realizado em diferentes horários do dia

PURPOSE: To evaluate the reproducibility of water drinking test (WDT) performed at different times of the day, in primary open angle glaucoma (POAG) patients and normal individuals. METHODS: Fifteen patients with POAG and 30 normal individuals underwent three WDTs at different times of the day (7 AM, 12 PM, and 5 PM) on 3 different days. Test results in POAG patients and normal individuals were compared. Agreement and correlation of intraocular pressure (IOP) baseline levels, peak levels, and IOP change (peak IOP - baseline IOP) on tests performed at different times were evaluated. Only right eye measurements were analyzed. RESULTS: Mean baseline IOP, peak IOP and IOP change were significantly higher in POAG patients than in normal individuals, at all time intervals (p3 mmHg), even though Pearson's test revealed good correlation among the results. CONCLUSION: The mean IOP peak and mean IOP change observed during WDT are significantly higher in POAG patients than in control individuals. Low levels of agreement among WDTs performed at different times of the day suggest a poor reproducibility of WDT, which may limit its applicability for the diagnosis and follow-up of glaucoma.OBJETIVO: Avaliar a reprodutibilidade do teste de sobrecarga hídrica (TSH) em diferentes horários em que é realizado, em pacientes com glaucoma primário de ângulo aberto (GPAA) e em indivíduos normais. MÉTODOS: Quinze pacientes com GPAA e 30 indivíduos normais foram submetidos a três TSHs, realizados em diferentes horários do dia (às 7:00 h, 12:00 h e 17:00 h), em três dias diferentes. Foram comparados os resultados dos testes em pacientes com GPAA e indivíduos normais. Foram analisadas a concordância e a correlação entre os valores de medida basal, pico e variação de pressão intraocular (PIO) (pico de PIO - PIO basal) nos testes realizados nos diferentes horários. Apenas as medidas do olho direito foram analisadas. RESULTADOS: Os valores médios de medida basal, pico e variação de PIO foram significativamente maiores nos pacientes glaucomatosos que nos indivíduos normais, em todos os horários (p3 mmHg), apesar de o teste de Pearson demonstrar boa correlação entre os resultados. CONCLUSÃO: O TSH apresenta valores de pico e variações da PIO significativamente maiores em pacientes glaucomatosos que em indivíduos normais. Os baixos níveis de concordância entre os TSHs realizados em diferentes horários do dia sugerem uma baixa reprodutibilidade do TSH, que pode limitar sua aplicabilidade para diagnóstico e acompanhamento do glaucoma.283290Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

The use of mitomycin C in combined procedures

Purpose: To analyze the efficacy and safety of intraope-rative mitomycin C (MMC) in combined procedures (extra-capsular cataract extraction + trabeculectomy). Methods: Twenty-four patients were randomized to either MMC (0.5 mg/ml) (n = 14) or saline solution (n = 10) for 3 minutes during the combined procedure. Results: Twelve months after surgery, mean IOP in the MMC group (13.2 ± 2.9 mmHg) was significantly lower than in the control group (16.3 ± 3.9 mmHg) (p = 0.02). The mean number of medications used during the 12-month follow-up in the control group (1.33 ± 0.5) was significantly higher than in the MMC-treated group (0.5 ± 0.5) (p = 0.005). Life table analysis showed a significantly higher probability of IOP control in the MMC group than in the control group (p < 0.01). Conclusions: Intraoperative MMC is safe and effective in pro-moting a better IOP control and reducing the need for postoperative antiglaucoma medications. We suggest intraope-rative MMC to be routinely employed in combined procedures.Objetivo: Avaliar a eficácia e a segurança do uso intra-operatório da mitomicina C (MMC) em cirurgias combinadas (facectomia extracapsular + trabeculectomia). Métodos: Vinte e quatro pacientes foram randomizados para cirurgia combinada com MMC (0,5 mg/ml) (n = 14) ou solução salina (n = 10) por 3 minutos. Resultados: Após 12 meses de seguimento, a PIO média do grupo que recebeu MMC (13,2 ± 2,9 mmHg) foi significativamente menor que a observada no grupo controle (16,3 ± 3,9 mmHg) (p = 0,02). O número médio de medicações utilizadas no grupo controle (1,33 ± 0,5) foi significativamente maior do que no grupo tratado com MMC (0,5 ± 0,5) 12 meses após a cirurgia (p = 0,005). A curva de sobrevida de Kaplan Meyer mostrou uma probabilidade de sucesso significativamente maior no grupo que recebeu MMC no intraoperatório (p < 0,05). Conclusões: O uso intra-operatório de MMC foi seguro e altamente eficaz em promover um melhor controle pressórico e reduzir a necessidade do uso de medicações antiglaucomatosas. Sugere-se que a MMC seja usada de rotina em pacientes submetidos à cirurgia combinada com a técnica extracapsular.57758

Helicobacter pylori in both the sinuses and the stomach

Background: The role played by Helicobacter pylori in the sinuses, and its association with the same organism’s gastric infection, are still unclear. Methods: In order to compare H.pylori colonization patterns in the nose and stomach we conducted a cohort analysis of 14 patients, eligible for sinus surgery due to chronic medically refractory rhinosinusitis, who were tested for simultaneous presence of H. pylori, by histology, culture and polymerase chain reaction, in pathologic sinus tissue collected during surgery and in gastric mucosa obtained through gastroduodenal endoscopy. Results: H. pylori DNA was found in the sinus mucosa of 15.4% of patients with chronic rhinosinusitis, and all of them showed concurrent H. pylori stomach infection. Sinus colonization was not found without simultaneous gastric colonization, although most patients with gastric infection did not have the bacterial DNA in their sinuses. H. pylori’s presence in the nose was not associated with local inflammatory status, and no cultures could be obtained from any of the sinus tissue samples, including those positive for H. pylori DNA. Conclusions: Only H. pylori DNA, and not the culturable active form of the microorganism, could be found in the sinus mucosa of some patients with H. pylori gastric infection. We could not find evidence, however, that the bacterium’s presence in the nose contributes to local mucosal inflammation.info:eu-repo/semantics/publishedVersio
