Resumo Esta investigação apresenta a alimentação e a atividade alimentar de bagres ribeirinhos Rita rita ameaçados de extinção, no período de fevereiro de 2017 a janeiro de 2018. Um total de 225 peixes foi analisado quanto ao conteúdo do estômago, caracterizando os itens alimentares dominantes e as características morfométricas. Os resultados apresentaram dez principais itens alimentares consumidos, preferencialmente escamas e ovos de peixes, teleósteos, copépodes, cladóceros, rotíferos e moluscos. O comprimento total e o peso corporal dos peixes variaram entre 9-34 cm (20,53 ± 6,90 cm) e 10-400 g (9125,94 ± 102,07 g), respectivamente. O índice de importância relativa (IRI%) mostrou a importância dos rotíferos sobre os demais itens alimentares. O índice de sobreposição de dieta de Morisita indicou variações sazonais nas dietas de bagres no verão e nas monções, exibindo a menor sobreposição, enquanto a sobreposição máxima ocorreu durante as estações das monções e do inverno. A escala multidimensional não métrica (nMDS) indicou a estreita associação entre os itens alimentares disponíveis durante o verão e o inverno, com uma diferença significativa entre as estações (ANOSIM, R = 0,638, P = 0,013). O índice de amplitude de nicho de Levin foi organizado na ordem de 0,88 > 0,81 > 0,78 > 0,63 > 0,43 para as classes de tamanho de V, IV, III, II e I, respectivamente. O PCA explicou 95,39% da variação total entre os itens alimentares e os grupos de tamanho de peixes. Peixes de pequeno porte apresentaram maior correlação com itens alimentares adequados ao tamanho da boca. Em conclusão, a variedade e a frequência dos itens alimentares registrados indicaram plasticidade alimentar considerável e comportamento alimentar oportunista, com uma mudança da natureza carnívora para onívora. Este estudo pode fornecer informações úteis sobre os hábitos alimentares e de alimentação de R. rita e apresentar subsídios para a preparação de sua dieta em futuras práticas de aquicultura.
Abstract This investigation presents the food and feeding activity of and endangered riverine catfish Rita rita, during February 2017-January 2018. A total of 225 fish individuals was analyzed for stomach contents by characterizing the dominant food items and morphometric features. The results divulged ten major food items consumed, preferably fish scales and eggs, teleost fishes, copepods, cladocerans, rotifers, and mollusks. Total length and body weight of fish varied between 9-34 cm (20.53 ± 6.90 cm) and 10-400 g (9125.94 ± 102.07 g), respectively. The index of relative importance (IRI%) showed the importance of rotifers over the other food items. Morisita’s index of diet overlap indicated seasonal variations in catfish diets with summer and monsoon displaying the least overlap, while maximum overlap during monsoon and winter seasons. The non-metric multidimensional scaling (nMDS) indicated the close association between the food items available during summer and winter seasons with a significant difference among the seasons (ANOSIM, R = 0.638, P = 0.013). Levin’s niche breadth index arranged in the order of 0.88>0.81>0.78>0.63>0.43 for the size classes of V, IV, III, II and I, respectively. The PCA explained 95.39% of the total variance among the food items and fish size groups. Small-sized fish individuals displayed a greater correlation with food items suitable for their mouth size. In conclusion, the variety and frequency of food items recorded indicated considerable feeding plasticity and opportunistic feeding behavior with a shift from carnivorous to omnivorous feeding nature. This study could render useful information on the food and feeding habits of R. rita and provide background for preparing its diet for future aquaculture practices.

ABSTRACT Objective: Many patients who undergo inflatable penile prosthesis (IPP) replacement are often upsized to larger cylinders, suggesting the IPP may serve as a tissue expander and increase internal penile length. The objective of this study is to evaluate whether cylinder length increases with subsequent IPP insertion. Materials and Methods: We queried American Medical Systems and Coloplast Patient Information Form databases to identify patients who underwent IPP placement and replacement between 2004-2013. Patients were grouped by device type and time to replacement (<2 or ≥2 years). We selected the 2-year mark for subgroup analysis to allow time for tissue expansion to occur and to exclude patients who underwent early explantation (e.g. erosion or infection). Results: Two thousand, seven hundred and forty nine patients (1,532 AMS 700 LGX, 717 AMS 700 CX, and 500 Coloplast Titan) met the inclusion criteria. Mean time between implants was earlier for LGX (29 months) than CX (39 months) and Titan (48 months) patients (p<0.001). Patients who underwent device replacement at <2 years did not experience an increase in mean cylinder length. On the contrary, patients who underwent device replacement at ≥2 years did experience significant increases in mean cylinder length (LGX 1.2 cm, CX 1.1 cm, and Titan 0.9 cm, p<0.001). The mean increases in length at ≥2 years were similar between the 3 devices (p=0.20). Sixty percent of patients demonstrated increases of >0.5 cm and 40% demonstrated increases of ≥1 cm. Conclusions: As demonstrated, the IPP may provide tissue expansion over time. Further evaluation is needed to determine if increased cylinder length correlates to increased functional length and patient satisfaction.

Abstract Patients with mucopolysaccharidosis (MPS), and Morquio A syndrome (MPS IVA) in particular, often report substantial pain burden. MOR-008 was a randomized, double-blind, pilot study assessing the safety and efficacy, including impact on patient-reported pain, of 52 weeks of treatment with elosulfase alfa (at a dose of 2.0 or 4.0 mg/kg/week) in patients with Morquio A syndrome (?7 years old). Assessment of pain at baseline revealed that patients (N = 25) had a mean number of pain locations of 5.7, mean pain intensity score of 4.6 (indicative of medium pain), and a mean number of selected pain descriptors of 7.4 words. Treatment with elosulfase alfa improved subjective pain score (reduced to 3.2), pain locations (reduced by a mean of 1 location), and pain descriptor words (reduced to 4.9 words) over 1 year (52 weeks), suggesting that elosulfase alfa can reduce pain in some patients with Morquio A.

African animal trypanosomiasis causes significant economic losses in sub-Saharan African countries because of livestock mortalities and reduced productivity. Trypanosomes, the causative agents, are transmitted by tsetse flies (Glossina spp.). In the current study, we compared and contrasted the virulence characteristics of five Trypanosoma congolense and Trypanosoma brucei isolates using groups of Swiss white mice (n = 6). We further determined the vectorial capacity of Glossina pallidipes, for each of the trypanosome isolates. Results showed that the overall pre-patent (PP) periods were 8.4 ± 0.9 (range, 4-11) and 4.5 ± 0.2 (range, 4-6) for T. congolense and T. brucei isolates, respectively (p < 0.01). Despite the longer mean PP, T. congolense-infected mice exhibited a significantly (p < 0.05) shorter survival time than T. brucei-infected mice, indicating greater virulence. Differences were also noted among the individual isolates with T. congolense KETRI 2909 causing the most acute infection of the entire group with a mean ± standard error survival time of 9 ± 2.1 days. Survival time of infected tsetse flies and the proportion with mature infections at 30 days post-exposure to the infective blood meals varied among isolates, with subacute infection-causing T. congolense EATRO 1829 and chronic infection-causing T. brucei EATRO 2267 isolates showing the highest mature infection rates of 38.5% and 23.1%, respectively. Therefore, our study provides further evidence of occurrence of differences in virulence and transmissibility of eastern African trypanosome strains and has identified two, T. congolense EATRO 1829 and T. brucei EATRO 2267, as suitable for tsetse infectivity and transmissibility experiments.

Abstract The mucopolysaccharidosis (MPS) disorders are rare genetic diseases caused by deficiencies in lysosomal enzymes involved in the degradation of glycosaminoglycans, leading to pulmonary, cardiac and neurological dysfunctions, skeletal anomalies, impaired vision, and/or hearing and shortened life spans. Whereas in the past, few individuals with MPS reached adulthood, better diagnosis, multidisciplinary care, and new therapies have led to an increasing number of adult patients with MPS. Therefore, fertility and pregnancy questions in this patient population are becoming more important. Management of fertility issues and pregnancy in patients with MPS is challenging due to the lack of documented cases and a dearth in the literature on this topic. This review presents multidisciplinary expert opinions on managing fertility and pregnancy based on case studies and clinical experience presented at a meeting of MPS specialists held in Berlin, Germany, in April 2015. An overview of the existing literature on this subject is also included.

ABSTRACTINTRODUCTION: Monte Carlo simulations have been used for selecting optimal antibiotic regimens for treatment of bacterial infections. The aim of this study was to assess the pharmacokinetic and pharmacodynamic target attainment of intravenous β-lactam regimens commonly used to treat bloodstream infections (BSIs) caused by Gram-negative rod-shaped organisms in a Brazilian teaching hospital.METHODS: In total, 5,000 patients were included in the Monte Carlo simulations of distinct antimicrobial regimens to estimate the likelihood of achieving free drug concentrations above the minimum inhibitory concentration (MIC; fT > MIC) for the requisite periods to clear distinct target organisms. Microbiological data were obtained from blood culture isolates harvested in our hospital from 2008 to 2010.RESULTS: In total, 614 bacterial isolates, including Escherichia coli, Enterobacterspp., Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa, were analyzed Piperacillin/tazobactam failed to achieve a cumulative fraction of response (CFR) > 90% for any of the isolates. While standard dosing (short infusion) of β-lactams achieved target attainment for BSIs caused by E. coliand Enterobacterspp., pharmacodynamic target attainment against K. pneumoniaeisolates was only achieved with ceftazidime and meropenem (prolonged infusion). Lastly, only prolonged infusion of high-dose meropenem approached an ideal CFR against P. aeruginosa; however, no antimicrobial regimen achieved an ideal CFR against A. baumannii.CONCLUSIONS:These data reinforce the use of prolonged infusions of high-dose β-lactam antimicrobials as a reasonable strategy for the treatment of BSIs caused by multidrug resistant Gram-negative bacteria in Brazil.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

OBJECTIVES: We evaluated a strategy for preventing tuberculosis (TB) in communities most affected by it. METHODS: In 1996, we mapped reported TB cases (1985-1995) and positive tuberculin skin test (TST) reactors (1993-1995) in Smith County, Texas. We delineated the 2 largest, densest clusters, identifying 2 highest-incidence neighborhoods (180 square blocks, 3153 residents). After extensive community preparation, trained health care workers went door-to-door offering TST to all residents unless contraindicated. TST-positive individuals were escorted to a mobile clinic for radiography, clinical evaluation, and isoniazid preventive treatment (IPT) as indicated. To assess long-term impact, we mapped all TB cases in Smith County during the equivalent time period after the project. RESULTS: Of 2258 eligible individuals, 1291 (57.1%) were tested, 229 (17.7%) were TST positive, and 147 were treated. From 1996 to 2006, there were no TB cases in either project neighborhood, in contrast with the preintervention decade and the continued occurrence of TB in the rest of Smith County. CONCLUSIONS: Targeting high-incidence neighborhoods for active, community-based screening and IPT may hasten TB elimination in the United States
OBJETIVOS: Evaluamos una estrategia para la prevención de la tuberculosis en las comunidades más afectadas por esta enfermedad. MÉTODOS: En 1996, trazamos un mapa de los casos de tuberculosis notificados (1985-1995) y de las personas con reacción positiva a la prueba de la tuberculina (1993-1995) en el condado de Smith, Texas, Estados Unidos de América. Definimos los dos conglomerados de mayor tamaño y densidad, identificando los dos vecindarios con mayor incidencia (180 manzanas y 3 153 residentes). Tras una preparación intensiva de la comunidad, personal sanitario capacitado ofreció a todos los residentes, de vivienda en vivienda, la posibilidad de hacerse la prueba de la tuberculina, a menos que estuviera contraindicado. A las personas con resultados positivos en esta prueba se las acompañó a un consultorio móvil para realizarles ahí radiografías, una evaluación clínica y, según fuera pertinente, proceder con el tratamiento preventivo con isoniazida. Para evaluar las repercusiones a largo plazo, trazamos un mapa de todos los casos de tuberculosis que se registraron en el condado de Smith durante el período equivalente después del proyecto. RESULTADOS: De las 2 258 personas que cumplían los requisitos para participar, 1 291 (57,1%) se sometieron a la prueba de la tuberculina, 229 (17,7%) presentaron resultados positivos en dicha prueba y 147 fueron tratadas. De 1996 al 2006, no se registró ningún caso de tuberculosis en ninguno de los vecindarios del proyecto, a diferencia de lo ocurrido en el decenio anterior a la intervención y en el resto del condado de Smith, donde aparecieron continuamente casos de tuberculosis. CONCLUSIONES: Dirigirse a los vecindarios con una incidencia alta para realizar el tamizaje activo en la comunidad y aplicar tratamiento preventivo con isoniazida puede acelerar la eliminación de la tuberculosis en los Estados Unidos.

OBJECTIVE: To evaluate the safety and coverage benefits of auto-disable (AD) syringes, weighed against the financial and logis- tical costs, and to create appropriate health policies in Madagascar. METHODS: Fifteen clinics in Madagascar, trained to use AD syringes, were randomized to implement an AD syringe only, mixed (AD syringes used only on non-routine immunization days), or sterilizable syringe only (control) programme. During a five-week period, data on administered vaccinations were collected, interviews were conducted, and observations were recorded. FINDINGS: The use of AD syringes improved coverage rates by significantly increasing the percentage of vaccines administered on non-routine immunization days (AD-only 4.3%, mixed 5.7%, control 1.1% (P<0.05)). AD-only clinics eliminated sterilization sessions for vaccinations, whereas mixed clinics reduced the number of sterilization sessions by 64%. AD syringes were five times more expensive than sterilizable syringes, which increased AD-only and mixed clinics’ projected annual injection costs by 365% and 22%, respectively. However, introducing AD syringes for all vaccinations would only increase the national immunization budget by 2%. CONCLUSION: The use of AD syringes improved vaccination coverage rates by providing ready-to-use sterile syringes on non-routine immunization days and decreasing the number of sterilization sessions, thereby improving injection safety. The mixed programme was the most beneficial approach to phasing in AD syringes and diminishing logistical complications, and it had minimal costs. AD syringes, although more expensive, can feasibly be introduced into a developing country’s immunization programme to improve vaccination safety and coverage.
OBJETIVO: Evaluar la seguridad y los beneficios de las jeringas autodestruibles (AD) en términos de cobertura vacunal, contraponiéndolos a los costos financieros y logísticos, y formular políticas sanitarias adecuadas en Madagascar. MÉTODOS: Quince dispensarios de Madagascar entrenados en el uso de las jeringas AD fueron asignados aleatoriamente a un grupo que sólo utilizó jeringas AD, a un grupo mixto que sólo utilizó las jeringas AD fuera de los días de inmunización sistemática o a un grupo que sólo utilizó jeringas esterilizables (control). Durante un periodo de cinco semanas se registraron datos sobre las vacunaciones administradas, se realizaron entrevistas y se registraron las observaciones. RESULTADOS: El uso de las jeringas AD mejoró las tasas de cobertura gracias a un aumento significativo del porcentaje de vacunas administradas fuera de los días de inmunización sistemática (sólo AD: 4,3%; mixto: 5,7%; control: 1,1% [P< 0,05]). Los dispensarios que sólo utilizaron AD eliminaron las sesiones de esterilización para las vacunaciones, mientras que los dispensarios "mixtos" redujeron el número de dichas sesiones en un 64%. Las jeringas AD fueron cinco veces más caras que las esterilizables, lo cual incrementó los costos anuales previstos de las inyecciones en un 365% y un 22%, respectivamente, en los dispensarios que sólo utilizaron AD y en los dispensarios "mixtos". Sin embargo, la utilización de las jeringas AD en todas las vacunaciones sólo habría incrementado el presupuesto nacional de vacunación en un 2%. CONCLUSIÓN: El uso de las jeringas AD mejoró las tasas de cobertura vacunal, gracias a que permitió proporcionar jeringas estériles fáciles de usar en días no destinados específicamente a la inmunización sistemática y a que redujo el número de sesiones de esterilización, mejorando así la seguridad de las inyecciones. El programa mixto fue el enfoque más beneficioso para introducir paulatinamente las jeringas AD y reducir las complicaciones logísticas, y tuvo costos mínimos. Aunque son más caras, es posible introducir las jeringas AD en un programa de inmunización de un país en desarrollo para mejorar la seguridad y la cobertura de la vacunación.
OBJECTIF: Evaluer, en termes de sécurité et de couverture, les avantages des seringues autobloquantes, par rapport au coût financier et aux difficultés logistiques, et élaborer les politiques de santé appropriées à Madagascar. MÉTHODES: Quinze dispensaires de Madagascar, dont le personnel avait été formé à utiliser les seringues autobloquantes, ont été répartis en trois groupes pour mener un programme d'évalua-tion : groupe seringues autobloquantes seules, groupe mixte seringues autobloquantes (utilisées uniquement hors journées de vaccination systématique) et seringues stérilisables, groupe seringues stérilisables seules (groupe témoin). Pendant cinq semaines, les données concernant les vaccinations administrées ont été recueillies, des entretiens ont été réalisés et les observations ont été notées. RÉSULTATS: L'utilisation des seringues autobloquantes a amélioré le taux de couverture en augmentant significativement le pourcentage de vaccinations hors journées de vaccination systématique (groupe seringues autobloquantes seules : 4,3 % ; groupe mixte : 5,7 % ; groupe témoin : 1,1 % [p<0,05]). Dans les dispensaires n'employant que des seringues autobloquantes, la stérilisation n'a plus été utilisée pour la vaccination, tandis que dans les dispensaires utilisant les deux types de seringues, le nombre de stérilisations a été réduit de 64 %. Le coût des seringues autobloquantes est cinq fois plus élevé que celui des seringues stérilisables, ce qui a augmenté le coût annuel projeté des injections de respectivement 365 % et 22 % dans les dispensaires n'utilisant que les seringues autobloquantes et dans ceux utilisant les deux types de seringues. Cependant, l'introduction des seringues autobloquantes pour toutes les vaccinations n'augmenterait le budget du programme national de vaccination que de 2 %. CONCLUSION: L'utilisation des seringues autobloquantes a amélioré la couverture vaccinale, en permettant d'avoir à disposition des seringues prêtes à l'emploi en dehors des journées de vaccination systématique et en diminuant le nombre de stérilisations, ce qui a augmenté la sécurité des injections. Le programme mixte représente l'approche la plus intéressante pour introduire les seringues autobloquantes et diminue les complications logistiques; son coût est en outre minimal. L'introduction des seringues autobloquantes dans le programme de vaccination d'un pays en développement pour améliorer la sécurité et la couverture vaccinales apparaît faisable, même si leur coût est plus élevé.
