Parameterization and Evaluation of Predictions of DSSAT/CANEGRO for Brazilian Sugarcane

The DSSAT/CANEGRO model was parameterized and its predictions evaluated using data from five sugarcane (Sacchetrum spp.) experiments conducted in southern Brazil. The data used are from two of the most important Brazilian cultivars. Some parameters whose values were either directly measured or considered to be well known were not adjusted. Ten of the 20 parameters were optimized using a Generalized Likelihood Uncertainty Estimation (GLUE) algorithm using the leave-one-out cross-validation technique. Model predictions were evaluated using measured data of leaf area index (LA!), stalk and aerial dry mass, sucrose content, and soil water content, using bias, root mean squared error (RMSE), modeling efficiency (Eff), correlation coefficient, and agreement index. The Decision Support System for Agrotechnology Transfer (DSSAT)/CANEGRO model simulated the sugarcane crop in southern Brazil well, using the parameterization reported here. The soil water content predictions were better for rainfed (mean RMSE = 0.122mm) than for irrigated treatment (mean RMSE = 0.214mm). Predictions were best for aerial dry mass (Eff = 0.850), followed by stalk dry mass (Eff = 0.765) and then sucrose mass (Eff = 0.170). Number of green leaves showed the worst fit (Eff = -2.300). The cross-validation technique permits using multiple datasets that would have limited use if used independently because of the heterogeneity of measures and measurement strategies.

Estudo retrospectivo (histórico) da dengue no Brasil: características regionais e dinâmicas

A dengue no Brasil incide tipicamente nos meses mais quentes do ano, sem diferenças qualitativas para as regiões brasileiras, porém, com diferenças quantitativas importantes, dividindo o país em dois grupos distintos quanto ao número de notificações de casos. O primeiro grupo compreende as regiões Nordeste e Sudeste, que deteve cerca de 86% das notificações, enquanto o segundo (regiões Sul, Centro-Oeste e Norte) é responsável por um número significativamente menor. Os índices vetoriais estavam associados primariamente ao tamanho das populações, sendo mais freqüentes os índices abaixo do valor de risco e ainda assim, nesta condição, ocorreram epidemias. Não foi observada correlação positiva entre epidemias e densidades vetoriais.

Efeito do gelo clorado sobre parâmetros químicos e microbiológicos da carne de carpa capim (Ctenopharyngodon idella)

A rápida perecibilidade dos peixes provoca perdas na industrialização e comercialização desse alimento. No presente trabalho, avaliou-se a eficiência da utilização de gelo clorado para ampliar a vida-de-prateleira de carpa capim (Ctenopharyngodon idella). Foram realizadas contagens de microrganismos aeróbios mesófilos e psicrotróficos na carne, e determinada a concentração de bases voláteis totais e o pH da carne de carpas armazenadas inteiras, sob refrigeração (3±1ºC), cobertas com gelo sem cloro ou clorado (5ppm), ao longo de 20 dias. O cloro reduziu significativamente (p<0,05) as populações de microrganismos aeróbios mesófilos e psicrotróficos, o pH e os valores iniciais das bases voláteis totais (BVT) na carne de carpa capim. Os valores de BVT foram baixos e tiveram pouca variação ao longo da armazenagem. Os resultados demonstraram que a vida-de-prateleira de carpa capim pode ser aumentada em aproximadamente 3 dias utilizando cloro no gelo de armazenagem; bem como, que os parâmetros pH e bases voláteis totais não são bons indicadores para avaliar a deterioração desse peixe.

Qualidade microbiológica no processamento do frango assado em unidade de alimentação e nutrição

As toxiinfecções alimentares de origem microbiana têm sido reconhecidas como um problema de saúde pública mais abrangente. Os produtos perecíveis protéicos são considerados importantes em relação ao controle higiênico-sanitário. Portanto, o objetivo deste trabalho foi analisar a qualidade microbiológica do processo produtivo do frango assado. O monitoramento da preparação foi realizado por meio de análises microbiológicas do frango cru e assado, swabs de bancadas, cubas, mãos dos manipuladores. O estudo bacteriológico foi desenvolvido no total de 96 amostras que foram submetidas às seguintes análises microbiológicas: Coliformes totais e fecais, Estafilococos coagulase positivo, Salmonella spp. e Clostrídio Sulfito Redutor somente no frango assado. As amostras das bancadas, cubas e mãos dos manipuladores após a higienização e frango assado demonstraram ausência dos microorganismos pesquisados. Das amostras de frango cru, 9,9% apresentaram Coliformes fecais (>15.000 NMP - limite da legislação) e 6,6%, Estafilococus coagulose positivo. Todas as amostras apresentaram ausência de Salmonella spp. As bancadas e mãos, durante a manipulação do frango, apresentaram contaminação por Coliformes fecais, relacionada à contaminação da matéria-prima. Os resultados demonstram que as etapas do processamento estão com qualidade microbiológica adequada, garantido a segurança do produto final.

Neoadjuvant chemoradiotherapy with or without panitumumab in patients with wild-type KRAS, locally advanced rectal cancer (LARC): a randomized, multicenter, phase II trial SAKK 41/07

BACKGROUND We conducted a randomized, phase II, multicenter study to evaluate the anti-epidermal growth factor receptor (EGFR) mAb panitumumab (P) in combination with chemoradiotherapy (CRT) with standard-dose capecitabine as neoadjuvant treatment for wild-type KRAS locally advanced rectal cancer (LARC). PATIENTS AND METHODS Patients with wild-type KRAS, T3-4 and/or N+ LARC were randomly assigned to receive CRT with or without P (6 mg/kg). The primary end-point was pathological near-complete or complete tumor response (pNC/CR), defined as grade 3 (pNCR) or 4 (pCR) histological regression by Dworak classification (DC). RESULTS Forty of 68 patients were randomly assigned to P + CRT and 28 to CRT. pNC/CR was achieved in 21 patients (53%) treated with P + CRT [95% confidence interval (CI) 36%-69%] versus 9 patients (32%) treated with CRT alone (95% CI: 16%-52%). pCR was achieved in 4 (10%) and 5 (18%) patients, and pNCR in 17 (43%) and 4 (14%) patients. In immunohistochemical analysis, most DC 3 cells were not apoptotic. The most common grade ≥3 toxic effects in the P + CRT/CRT arm were diarrhea (10%/6%) and anastomotic leakage (15%/4%). CONCLUSIONS The addition of panitumumab to neoadjuvant CRT in patients with KRAS wild-type LARC resulted in a high pNC/CR rate, mostly grade 3 DC. The results of both treatment arms exceeded prespecified thresholds. The addition of panitumumab increased toxicity.

Autologous hematopoietic stem cell transplantation vs intravenous pulse cyclophosphamide in diffuse cutaneous systemic sclerosis: a randomized clinical trial

IMPORTANCE High-dose immunosuppressive therapy and autologous hematopoietic stem cell transplantation (HSCT) have shown efficacy in systemic sclerosis in phase 1 and small phase 2 trials. OBJECTIVE To compare efficacy and safety of HSCT vs 12 successive monthly intravenous pulses of cyclophosphamide. DESIGN, SETTING, AND PARTICIPANTS The Autologous Stem Cell Transplantation International Scleroderma (ASTIS) trial, a phase 3, multicenter, randomized (1:1), open-label, parallel-group, clinical trial conducted in 10 countries at 29 centers with access to a European Group for Blood and Marrow Transplantation-registered transplant facility. From March 2001 to October 2009, 156 patients with early diffuse cutaneous systemic sclerosis were recruited and followed up until October 31, 2013. INTERVENTIONS HSCT vs intravenous pulse cyclophosphamide. MAIN OUTCOMES AND MEASURES The primary end point was event-free survival, defined as time from randomization until the occurrence of death or persistent major organ failure. RESULTS A total of 156 patients were randomly assigned to receive HSCT (n = 79) or cyclophosphamide (n = 77). During a median follow-up of 5.8 years, 53 events occurred: 22 in the HSCT group (19 deaths and 3 irreversible organ failures) and 31 in the control group (23 deaths and 8 irreversible organ failures). During the first year, there were more events in the HSCT group (13 events [16.5%], including 8 treatment-related deaths) than in the control group (8 events [10.4%], with no treatment-related deaths). At 2 years, 14 events (17.7%) had occurred cumulatively in the HSCT group vs 14 events (18.2%) in the control group; at 4 years, 15 events (19%) had occurred cumulatively in the HSCT group vs 20 events (26%) in the control group. Time-varying hazard ratios (modeled with treatment × time interaction) for event-free survival were 0.35 (95% CI, 0.16-0.74) at 2 years and 0.34 (95% CI, 0.16-0.74) at 4 years. CONCLUSIONS AND RELEVANCE Among patients with early diffuse cutaneous systemic sclerosis, HSCT was associated with increased treatment-related mortality in the first year after treatment. However, HCST conferred a significant long-term event-free survival benefit. TRIAL REGISTRATION isrctn.org Identifier: ISRCTN54371254.
