Cost-effectiveness comparison between pituitary down-regulation with a gonadotropin-releasing hormone agonist short regimen on alternate days and an antagonist protocol for assisted fertilization treatments

Objective: To compare cost-effectiveness between pituitary down-regulation with a GnRH agonist (GnRHa) short regimen on alternate days and GnRH antagonist (GnRHant) multidose protocol on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcome. Design: Prospective, randomized. Setting: A private center. Patient(s): Patients were randomized into GnRHa (n = 48) and GnRHant (n = 48) groups. Intervention(s): GnRHa stimulation protocol: administration of triptorelin on alternate days starting on the first day of the cycle, recombinant FSH (rFSH), and recombinant hCG (rhCG) microdose. GnRHant protocol: administration of a daily dose of rFSH, cetrorelix, and rhCG microdose. Main Outcome Measure(s): ICSI outcomes and treatment costs. Result(s): A significantly lower number of patients underwent embryo transfer in the GnRHa group. Clinical pregnancy rate was significantly lower and miscarriage rate was significantly higher in the GnRHa group. It was observed a significant lower cost per cycle in the GnRHa group compared with the GnRHant group ($5,327.80 ± 387.30 vs. $5,900.40 ± 472.50). However, mean cost per pregnancy in the GnRHa was higher than in the GnRHant group ($19,671.80 ± 1,430.00 vs. $11,328.70 ± 907.20). Conclusion(s): Although the short controlled ovarian stimulation protocol with GnRHa on alternate days, rFSH, and rhCG microdose may lower the cost of an individual IVF cycle, it requires more cycles to achieve pregnancy.

In vitro trypanocidal activity of solamargine and extracts from Solanum palinacanthum and Solanum lycocarpum of brazilian cerrado

O objetivo deste estudo foi avaliar a potencial atividade tripanocida do extrato bruto etanólico dos frutos de Solanum palinacanthum, Solanum lycocarpum e do glicoalcalóide solamargina. Pó do fruto seco de S. palinacanthum e S. lycocarpum foram submetidos a extracção por refluxo com etanol a 96% e solamargina foi isolada a partir do extrato bruto de S. palinacanthum. Foram determinadas de ambos os extratos e a solamargina a atividade tripanocida utilizando o ensaio colorimétrico MTT. O Extrato de S. palinacanthum mostrou-se mais ativo (IC50 = 175,9 µg.ml–1) de que o extrato de S. lycocarpum (IC50 = 194,7 µg.ml–1). A solamargina apresentou forte atividade tripanocida (IC50 = 15,3 µg.ml–1), o que pode explicar a melhor atividade de ambos os extratos. O benzonidazol (IC50 = 9,0 µg.ml–1) é a única droga utilizada para o tratamento da doença de Chagas. Estes resultados demonstram pela primeira vez que os extratos etanólicos obtidos a partir de frutos de S. palinacanthum e S. lycocarpum, além da solamargina apresentam uma atividade tripanocida potencial.

Maxillary sinus lift without grafting, and simultaneous implant placement: a prospective clinical study with a 51-month follow-up

A prospective clinical study of maxillary sinus lift procedures in the posterior region of the maxilla, using only blood clot as filling material, was conducted. Seventeen patients underwent a maxillary sinus lift procedure; 20 maxillary sinus regions were operated on and a total of 25 implants were placed. The sinus mucosa was lifted together with the anterior wall of the osteotomized maxilla and supported by the implants placed. Computed tomography (CT) scans were obtained immediately postoperative (T-initial) and at 3 (T-1) and 51(T-2) months postoperative for the measurement of linear bone height and bone density (by grey tones). Only one implant was lost in the first stage (96% success). After dental prosthesis placement and during up to 51 months of follow-up, no implant was lost (100% success, second stage). The difference in mean bone height between T-initial (5.94 mm) and T-1 (13.14 mm), and between T-initial and T-2 (11.57 mm), was statistically significant (both P < 0.001); comparison between T-1 and T-2 also presented a statistical difference (P < 0.001). Bone density had increased at the end of the period analyzed, but this was not statistically significant (P > 0.05). Thus, the maxillary sinus lift technique with immediate implant placement, filling with blood clot only, may be performed with a high success rate.

Associação entre a doença periodontal e doenças sistêmicas crônicas: revisão de literatura

Periodontal disease has been increasingly associated as a supporting factor, and even a precursor to some systemic diseases. Just aim of this paper was to analyze by reviewing the literature, the possible mechanisms involved in the etiopathogenesis of periodontal disease that are common to the current systemic diseases such as obesity, atherosclerosis, diabetes and rheumatoid arthritis. The articles were analyzed with in the publication period of the years 2006 to 2011 and were surveyed in the databases PubMed, LILACS and SciELO. Of a total of 907 articles found by searching the indices and their associations, were selected by inclusion criteria 93 articles. For the preparation of this literature review, only 24 articles were selected because they are based on inflammatory mechanisms, metabolic and infectious, where the considerations for the strongest associations in the literature. This literature review reinforces the association of periodontal disease with systemic diseases analyzed due to presence of inflammatory and immunological mechanisms and similar synergism betwen the two diseases, but some hypotheses still need further clarification. The professional should stick to recent discoveries associations to promote periodontal treatment in preventing the development of systemic diseases, as well as in maintaining the systemic health of patients already suffering from chronic systemic diseases.

O mapa de ponta-cabeça

Joaquin Torres Garcia reversed the position of the map of the continent, reaching South America north. This little drawing illustrates an article by Torres García, 1935, in which he advocates the creation of a "Escuela del Sur". This image illustrates a need in Latin America to seek their own ways. Torres-Garcia was inspired by the preColumbian American heritage for their symbolic and Constructivism proposes that Latin America look to the popular ancestral and cultural traditions and build an art itself through which the continent would no longer be a tributary of European culture. As production visual modern and contemporary Latin American context of globalization, takes the center / periphery relationship? The colonizer's model center/periphery relationship persists in the Latin American visual production? The technologies offered other ways of representation that break with the culture of repetition? These questions guide our research.

Microinversor integrado ao módulo fotovoltaico para sistemas conectados à rede elétrica utilizando controlador ressonante

This paper shows the modeling and control of a single-phase full-bridge inverter with high-frequency transformer that may be used as part of a two-stage converter with transformerless DC-DC side or as a single-stage converter (simple DC-AC converter) for grid-connected PV applications. The inverter is modeled in order to obtain a small-signal transfer function used to design the P+Resonant current controller. A highfrequency step-up transformer results in reduced voltage switches and better efficiency compared with converters in which the transformer is used on the DC-DC side. Simulations and experimental results with a 200 W prototype are shown. 1
