OBJECTIVES: The aims of this study were to assess the 1-year cost-effectiveness of a new combined immunosuppressive and anti-infectious regimen in kidney transplantation to prevent both rejection and infectious complications. METHODS: Patients (pts) transplanted from January 2000 to March 2003 (Group A) and treated with a conventional protocol were compared with pts submitted to a combined regimen including universal cytomegalovirus (CMV) prophylaxis between April 2003 and July 2005 (Group B). Costs were computed from the hospital accounting system for hospital stays, and official tariffs for outpatient visits. Patients with incomplete costs data were excluded from analysis. RESULTS: Fifty-three patients were analyzed in Group A, and 60 in Group B. Baseline characteristics including CMV serostatus were not significantly different between the two groups. Over 12 months after transplantation, acute rejections decreased from 41.5 percent in Group A to 6.7 percent in Group B (p < .001), and CMV infections from 47 percent to 15 percent (p < .001). Overall, readmissions decreased from 68 percent to 55 percent (p = .160), and average hospital days from 28 +/- 19 to 20 +/- 11 days (p < .007). The average number of outpatient visits decreased from 49 +/- 10 to 39 +/- 8 (p < .001). Average 1-year immunosuppressive and CMV prophylaxis costs (per patient) increased from CHF20,402 +/- 7,273 to 27,375 +/- 6,063 (p < .001), graft rejection costs decreased from CHF4,595 +/- 10,182 to 650 +/- 3,167 (p = .005), CMV treatment costs from CHF2,270 +/- 6,161 to 101 +/- 326 (p = .008), and outpatient visits costs from CHF8,466 +/- 1'721 to 6,749 +/- 1,159 (p < .001). Altogether, 1-year treatment costs decreased from CHF39'957 +/- 16,573 to 36,204 +/- 6,901 (p = .115). CONCLUSIONS: The new combined regimen administered in Group B was significantly more effective, and its additional costs were more than offset by savings associated with complications avoidance.

Although current anti-cancer protocols are reasonably effective, treatment-associated long-term side effects, induced by lack of specificity of the anti-cancer procedures, remain a challenging problem in pediatric oncology. TAT-RasGAP317-326 is a RasGAP-derived cell-permeable peptide that acts as a sensitizer to various anti-cancer treatments in adult tumor cells. In the present study, we assessed the effect of TAT-RasGAP317-326 in several childhood cancer cell lines. The RasGAP-derived peptide-induced cell death was analyzed in several neuroblastoma, Ewing sarcoma and leukemia cell lines (as well as in normal lymphocytes). Cell death was evaluated using flow cytometry methods in the absence or in the presence of the peptide in combination with various genotoxins used in the clinics (4-hydroperoxycyclophosphamide, etoposide, vincristine and doxorubicin). All tested pediatric tumors, in response to at least one genotoxin, were sensitized by TAT-RasGAP317-326. The RasGAP-derived peptide did not increase cell death of normal lymphocytes, alone or in combination with the majority of the tested chemotherapies. Consequently, TAT-RasGAP317-326 may benefit children with tumors by increasing the efficacy of anti-cancer therapies notably by allowing reductions in anti-cancer drug dosage and the associated drug-induced side effects.

The main object of this Master´s Thesis was to study the goodwill impairment testing under IAS 36. The aim was also to study the process of impairment testing in companies. The definition, treatment and impairment testing of goodwill were based on the interpretative literature of the standard, articles in trade papers and in international journals. Research methodology was descriptive, qualitative and normative. The empirical data was gathered from focused interviews of companies, consultant and auditor. In the impairment testing of goodwill under IAS 36 carrying amount of cash-generating unit is compared with unit´s recoverable amount, which is defined by either fair value less costs to sell or value in use. Value in use, which is based on unit´s net present value of the future cash flows, is clearly more generally used. The greatest black spots of testing are determination of cash-generating units and allocation of goodwill to them and determination of the discount rate. These black spots enable covering-up goodwill impairment. Companies testing processes differed, which makes comparison more difficult. The documentation of testing should also be invested more in companies.

This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs), and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: < 20% biomass production (V1); 21-40% (V2); 41-60% (V3); 61-80% (V4); and > 80% (V5). The maximum growth rate for plant height, D-leaf length, and stem diameter was observed at the end of the phenological stage V1 (390-411 DAP), and at the end of stage V5 these plant traits had average values of 106, 82, and 7 cm, respectively. The maximum biomass accumulation rates were observed at stages V4 and V5, resulting in a final fruit yield and total fresh biomass of 72 t ha-1 and 326 t ha-1, respectively. Finally, we estimated that 80% of the accumulated biomass may remain in the field after fruit and slip harvest, and could be incorporated as plant residue into the soil.

BACKGROUND: Oral contraceptives are known to reduce the incidence rate of endometrial cancer, but it is uncertain how long this effect lasts after use ceases, or whether it is modified by other factors. METHODS: Individual participant datasets were sought from principal investigators and provided centrally for 27 276 women with endometrial cancer (cases) and 115 743 without endometrial cancer (controls) from 36 epidemiological studies. The relative risks (RRs) of endometrial cancer associated with oral contraceptive use were estimated using logistic regression, stratified by study, age, parity, body-mass index, smoking, and use of menopausal hormone therapy. FINDINGS: The median age of cases was 63 years (IQR 57-68) and the median year of cancer diagnosis was 2001 (IQR 1994-2005). 9459 (35%) of 27 276 cases and 45 625 (39%) of 115 743 controls had ever used oral contraceptives, for median durations of 3·0 years (IQR 1-7) and 4·4 years (IQR 2-9), respectively. The longer that women had used oral contraceptives, the greater the reduction in risk of endometrial cancer; every 5 years of use was associated with a risk ratio of 0·76 (95% CI 0·73-0·78; p<0·0001). This reduction in risk persisted for more than 30 years after oral contraceptive use had ceased, with no apparent decrease between the RRs for use during the 1960s, 1970s, and 1980s, despite higher oestrogen doses in pills used in the early years. However, the reduction in risk associated with ever having used oral contraceptives differed by tumour type, being stronger for carcinomas (RR 0·69, 95% CI 0·66-0·71) than sarcomas (0·83, 0·67-1·04; case-case comparison: p=0·02). In high-income countries, 10 years use of oral contraceptives was estimated to reduce the absolute risk of endometrial cancer arising before age 75 years from 2·3 to 1·3 per 100 women. INTERPRETATION: Use of oral contraceptives confers long-term protection against endometrial cancer. These results suggest that, in developed countries, about 400 000 cases of endometrial cancer before the age of 75 years have been prevented over the past 50 years (1965-2014) by oral contraceptives, including 200 000 in the past decade (2005-14).

Neste trabalho foi realizado estudo comparativo em radiografias de tórax empregando técnicas de alta e baixa quilovoltagens, tendo como objetivo uma melhoria da qualidade técnica das radiografias, associada a uma redução nas doses fornecidas aos pacientes. O estudo foi realizado em 48 pacientes randomizados, com realização de 70 radiografias de tórax em incidência póstero-anterior, utilizando técnicas de alta quilovoltagem (120 kVp) e carga transmitida de 2,3 mAs, e técnicas de baixa quilovoltagem (70 kVp) e carga transmitida de 5 a 10 mAs. Os valores de doses de entrada na pele foram medidos com um Diamentor. A técnica de baixa quilovoltagem apresentou um aumento de 326% na dose fornecida ao paciente, quando comparada com a técnica de alta quilovoltagem. Com o uso das técnicas de alta quilovoltagem foi constatada, ainda, uma diminuição do número de radiografias de má qualidade que necessitavam repetição, poupando os equipamentos e reduzindo custos por conta da melhoria da qualidade da imagem radiográfica.

Objective To evaluate intra- and interobserver agreement in the identification of incidental enchondromas at knee magnetic resonance imaging, and to assess the prevalence of imaging findings. Materials and Methods Retrospective study reviewing 326 knee magnetic resonance images acquired in the period between November 2009 and September 2010. The images were independently and blindly analyzed by two specialists in musculoskeletal radiology, with the objective of identifying incidental enchondromas, presence of foci with signal similar to bone marrow and foci of signal absence suggestive of calcifications within the enchondromas. Inter- and intraobserver agreements were analyzed. Results Eleven lesions compatible with enchondromas (3.3%) were identified. The interobserver agreement for the presence of enchondroma was high. Prevalence of foci of bone marrow signal inside the enchondromas was of 54.55%, and foci suggestive of calcification corresponded to 36.36%. The intraobserver agreement for foci of bone marrow signal in enchondromas was perfect, and interobserver agreement was high. Conclusion The prevalence of incidental enchondromas in the current study was compatible with data in the literature. Excellent agreement was observed in the identification of enchondromas and in the assessment of imaging findings. A higher prevalence of fat signal foci was observed as compared with signal absence suggestive of calcifications.
