Recipients of solid organ transplants(SOT) and stem cell transplants(SCT) constitute a group of patients at risk for tuberculosis(TB) development. The prevalence of active TB in patients undergoing SOT is higher than in patients undergoing SCT, probably due to the shorter period of immunosuppression in the latter. We reviewed the importance of SCT in individuals with hematological malignancies. Most TB cases occur in transplant patients by reactivation of latent infection after immunosuppression, most often within the first year after transplant, leading to graft loss and in some cases, death. Relevant variables to assess the risk of TB infection in a transplant recipient include the donor's and recipient's medical histories, imaging results, microbiology and tuberculin skin test(TST) and interferon-gamma release assays(IGRA). TST is routinely performed in the donor and recipient before transplantation. If TST is > 5 mm in the recipient or > 10 mm in the donor, it is necessary to exclude active TB(pulmonary and renal). Chemopro-phylaxis is recommended in TST(+) recipients and in recipients with recent seroconversion, in donors with a history of untreated TB or in contact with an individual with active TB, if radiological images are suspicious and the IGRA is(+). The drug of choice is isoniazid. These topics are herewith reviewed.

Right iliac fossa pain remains a challenge for clinicians, since it requires considering several differential diagnoses. Acute appendicitis continues to be one of the most important diagnoses to confirm or to rule out in acute abdominal pain, due to the associated morbidity and mortality. Currently, imaging studies contribute to increase diagnostic certainty, but sometimes reveal unexpected findings, which may further complicate the diagnosis and therapeutic decisions. We present the case of an unusual image finding in the right iliac fossa, a calcification suggestive of gallstone ileus, in the context of an acute abdomen with an unusual transoperative finding, whose definitive diagnosis by pathology, was also rare.

We used a distance-sampling survey method and multivariate statistics to obtain a unique estimate of bird species density and seasonal variation in shade-coffee plantations. Our aim was to determine which cultivation practices among plantations contribute most to bird abundance. We conducted avian species counts at 200 points distributed across 10 shade-coffee plantations bordering the lower slopes of the Mombacho Volcano Natural Reserve, in western Nicaragua. We measured vegetation structure (coffee plants and overstory). We used principal components analysis (PCA) among 14 habitat variables to derive a single phyto-geoclimate summary measure (PGSM). We also used PCA to derive an avian abundance summary measure (AASM) from three bird survey variables, which proved to be a good predictor of bird density. We found higher bird species densities (AASM) in organic and traditional polyculture shade coffee plantations whose structurally complex and diverse overstory could be verified by PGSM. However, this finding was true only for birds that were habitat specialists. Our results provide further evidence for promoting organic coffee cultivation practices that maintain a structurally diverse overstory and help retain avian species richness and abundance in coffee plantations.

Microbiological control of feeds used in industrial poultry production has been increasingly important due to the demands of the market for food safety, as well as the need to ensure better quality of the digestive system of the birds. Microbiological analysis carried out in raw material used in feed production, especially feather, meat, and organ meal, has shown contamination by Clostridium perfringens. In order to study the presence of Clostridium perfringens, a total of 354 samples of feed and raw material were analyzed from January 2011 to July 2013. Samples came from four companies located in the state of São Paulo, with a total of 166 samples of meat meal, 24 samples of feather meal, 43 samples of organ meal, and 121 samples of feed. The following results were obtained: 88 (53%), 15 (62.5%), 16 (37.21%), and 23 (19%) samples were positive for Clostridium perfringens in each group of samples, respectively, with counts ranging from 2.0 × 102 to 7.0 × 103 CFU/g.

To provide long-term simulations of climate change at higher resolution, Regional Climate Models (RCMs) are nested in global climate models (GCMs). The objective of this work is to evaluate the Eta RCM simulations driven by three global models, the HadGEM2-ES, BESM, and MIROC5, for the present period, 1961-1990. The RCM domain covers South America, Central America, and Caribbean. These simulations will be used for assessment of climate change projections in the region. Maximum temperatures are generally underestimated in the domain, in particular by MIROC5 driven simulations, in summer and winter seasons. Larger spread among the simulations was found in the minimum temperatures, which showed mixed signs of errors. The spatial correlations of temperature simulations against the CRU observations show better agreement for the MIROC5 driven simulations. The nested simulations underestimate precipitation in large areas over the continent in austral summer, whereas in winter overestimate occurs in southern Amazonia, and underestimate in southern Brazil and eastern coast of Northeast Brazil. The annual cycle of the near-surface temperature is underestimated in all model simulations, in all regions in Brazil, and in most of the year. The temperature and precipitation frequency distributions reveal that the RCM and GCM simulations contain more extreme values than the CRU observations. Evaluations of the climatic extreme indicators show that in general hot days, warm nights, and heat waves are increasing in the period, in agreement with observations. The Eta simulations driven by HadGEM2-ES show wet trends in the period, whereas the Eta driven by BESM and by MIROC5 show trends for drier conditions.

A quantitative ^(1)H NMR method(qHNMR)was used to measure the trigonelline content in the leaves of six species of the Annona *** methodology employed compared the intensities of the signals at δ9.14(H-2)andδ0.00,the internal standard TSP-d_(4).This measuring method was able to establish the concentration of trigonelline in the range from 0.67 to 10.04 mg·g^(-1) depending on the investigated extract.
