Desenvolvimento, produtividade e atributos qualitativos de cultivares de cana-de-açúcar fertirrigadas por gotejamento subsuperficial

The present study aimed to evaluate the development, yield and quality of four sugarcane cultivars fertigated by subsurface drip system. The experiment was carried out in Campinas-SP, Brazil, from January 2012 to November 2013, with the cultivars SP79-1011, IACSP94-2101, IACSP94-2094 and IACSP95-5000 subjected to daily irrigations. The irrigations depths were applied to bring soil moisture to field capacity. Soil moisture was monitored using soil moisture probes. Samples were collected along the crop cycle in order to evaluate crop development and yield, at the end of the first and second ratoons. Stalk height showed good correlation for the estimation of crop yield, with R2 equal to or higher than 0.96. The cultivar IACSP95-5000 showed the highest yield in the first ratoon. In the second ratoon the highest yield was observed in IACSP94-2101, followed by IACSP95-5000 and SP79-1011. Considering the yield results associated with the technological analysis, such as soluble solids content and apparent sucrose, the cultivar IACSP95-5000 excelled the others in the cultivation under subsurface drip irrigation.Objetivou-se, no presente estudo, avaliar o desenvolvimento, a produtividade e a qualidade de quatro cultivares de canas-de-açúcar fertirrigadas por gotejamento subsuperficial. O experimento foi realizado em Campinas, SP, Brasil, no período de janeiro de 2012 a novembro de 2013, com as cultivares SP79-1011, IACSP94-2101, IACSP94-2094 e IACSP95-5000 com irrigações diárias, sendo a lâmina aplicada para repor a umidade do solo à capacidade de campo. Para tanto foram utilizadas sondas visando à medição da umidade do solo enquanto ao longo dos ciclos foram realizadas biometrias e estimativas da produtividade nas socas. A produtividade final foi estimada no fim de cada soca. A altura dos colmos apresentou boa correlação para estimativa da produtividade da cultura com R2 igual ou maior que 0,96. A maior produtividade na primeira soca foi observada na cultivar IACSP95-5000 e na segunda soca a IACSP94-2101 foi a cultivar mais produtiva seguida das IACSP95-5000 e SP79-1011. Considerando os resultados de produtividade associados à análise tecnológica, como os teores de sólidos solúveis e sacarose aparente, a IACSP95-5000 se sobressaiu no cultivo com irrigação por gotejamento subsuperficial.20652553

Meningoradiculitis Due To Cryptococcus Neofermans In An Immunocompetent Patient.

Meningoradiculitis refers to combined involvement of meninges and nerve roots. The most frequent location is the lumbosacral region. Etiology is diverse, including inflammatory, infectious and neoplastic disorders. Meningoradiculitis is a rare form of involvement in cryptococcal infection. We describe a case of subacute lower limbs flaccid paresis diagnosed as lumbosacral meningoradiculitis in view of cerebrospinal fluid (CSF) inflammatory changes and typical enhancement on MRI of lumbar spine. Cryptococcus neoformans was isolated from CSF. Extensive screening yielded no immunodeficiencies.62147-

Clinical effectiveness and safety of analogue glargine in type 1 diabetes : systematic review and meta-analysis

INTRODUCTION: The use of insulin analogues for the treatment of type 1 diabetes mellitus (T1DM) is widespread; however, the therapeutic benefits still require further evaluation given their higher costs. Objective: To evaluate the effectiveness and safety of Analogue Glargine (AG) compared to Recombinant DNA insulin (rDNA) in patients with DM1 in observational studies, building on previous reviews of RCTs comparing NPH insulin and AG. METHODS: A systematic review (SR) with meta-analysis. The SR included cohort studies and registries available on PUBMED, LILACS, and CENTRAL as well as manual and gray literature searches. The meta-analysis was conducted in Review Manager ® 5.2 software. The primary outcomes were: glycohemoglobin (Hb1Ac), weight gain and hypoglycemia. Methodological quality was assessed using the Newcastle-Ottawa scale. RESULTS: Out of 796 publications, 11 studies were finally included. The meta-analysis favored AG in Hb1Ac outcomes (adult patients) and hypoglycemic episodes (p <0.05), but without reaching glycemic control (Hb1Ac to approximately 7%). The methodological quality of the studies was moderate, noting that 45% of studies were funded by pharmaceutical companies. CONCLUSION: Given the high heterogeneity of the studies, the discrete value presented by the estimated effect on effectiveness and safety, potential conflicts of interest of the studies and the appreciable higher cost of AG, there is still no support for recommending first line therapy with analogues. The role of analogues in the treatment DM1 could be better determined by further observational studies of good methodological quality to assess their long-term effectiveness, safety as well as cost-effectiveness

A study protocol to evaluate the relationship between outdoor air pollution and pregnancy outcomes

<p>Abstract</p> <p>Background</p> <p>The present study protocol is designed to assess the relationship between outdoor air pollution and low birth weight and preterm births outcomes performing a semi-ecological analysis. Semi-ecological design studies are widely used to assess effects of air pollution in humans. In this type of analysis, health outcomes and covariates are measured in individuals and exposure assignments are usually based on air quality monitor stations. Therefore, estimating individual exposures are one of the major challenges when investigating these relationships with a semi-ecologic design.</p> <p>Methods/Design</p> <p>Semi-ecologic study consisting of a retrospective cohort study with ecologic assignment of exposure is applied. Health outcomes and covariates are collected at Primary Health Care Center. Data from pregnant registry, clinical record and specific questionnaire administered orally to the mothers of children born in period 2007-2010 in Portuguese Alentejo Litoral region, are collected by the research team. Outdoor air pollution data are collected with a lichen diversity biomonitoring program, and individual pregnancy exposures are assessed with spatial geostatistical simulation, which provides the basis for uncertainty analysis of individual exposures. Awareness of outdoor air pollution uncertainty will improve validity of individual exposures assignments for further statistical analysis with multivariate regression models.</p> <p>Discussion</p> <p>Exposure misclassification is an issue of concern in semi-ecological design. In this study, personal exposures are assigned to each pregnant using geocoded addresses data. A stochastic simulation method is applied to lichen diversity values index measured at biomonitoring survey locations, in order to assess spatial uncertainty of lichen diversity value index at each geocoded address. These methods assume a model for spatial autocorrelation of exposure and provide a distribution of exposures in each study location. We believe that variability of simulated exposure values at geocoded addresses will improve knowledge on variability of exposures, improving therefore validity of individual exposures to input in posterior statistical analysis.</p

Jejunal Diverticular Perforation due to Enterolith

Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life-threatening and require early surgical treatment. Small bowel perforation secondary to jejunal diverticulitis by enteroliths is rare. The aim of this study was to report a case of small intestinal perforation caused by a large jejunal enterolith. An 86-year-old woman was admitted with signs of diffuse peritonitis. After initial fluid recovery the patient underwent emergency laparotomy. The surgery showed that she had small bowel diverticular disease, mainly localized in the proximal jejunum. The peritonitis was due to intestinal perforation caused by an enterolith 12 cm in length, localized inside one of these diverticula. The intestinal segment containing the perforated diverticulum with the enterolith was removed and an end-to-end anastomosis was done to reconstruct the intestinal transit. The patient recovered well and was discharged from hospital on the 5th postoperative day. There were no signs of abdominal pain 1 year after the surgical procedure. Although jejunal diverticular disease with its complications, such as formation of enteroliths, is difficult to suspect in patients with peritonitis, it should be considered as a possible source of abdominal infection in the elderly patient when more common diagnoses have been excluded
