A number of variables may influence the outcome of complete denture therapy. The objective of this study was to verify possible correlations between previous experience with dentures, patient expectation and the number of post-delivery adjustments with patient satisfaction after treatment. One hundred patients (mean age 61·9 ± 10·3) rated their previous experiences with complete dentures and their expectations before and satisfaction after treatment on a visual analogue scale (VAS) using scores from 0 (worst results) to 10 (best results). The number of post-delivery adjustments and other patient-related clinical variables was also noted. Patient expectation scores were higher than previous experience scores and satisfaction after treatment scores. Positive and weak correlations were found between previous chewing experiences with complete dentures, with regard to chewing expectations and comfort of use. Phonetics and comfort of use in previous experiences presented a positive correlation with expectations for chewing, aesthetics, phonetics and comfort of use. Groups of patients with different levels of education presented significant differences in expectation scores regarding comfort of use as well. A negative and weak correlation was found between phonetics satisfaction and the number of post-delivery adjustments. Patients' expectations for the therapy were higher than their satisfaction after treatment. Previous experiences with complete dentures could slightly influence patients' expectations and satisfaction, whereas lower scores for previous experience with complete dentures caused lower scores for both expectation and satisfaction. Patients' educational levels and the number of post-delivery adjustments influenced negatively the expectations about comfort of use and patient satisfaction, respectively. © 2013 John Wiley & Sons Ltd.

Among the hidden pieces of the giant puzzle, which is our Solar system, the origins of irregularsatellites of the giant planets stand to be explained, while the origins of regular satellites arewell explained by the in situ formation model through matter accretion. Once they are notlocally formed, the most acceptable theory predicts that they had been formed elsewhere andbecame captured later, most likely during the last stage of planet formation. However, underthe restricted three-body problem theory, captures are temporary and there is still no assistedcapture mechanism which is well established. In a previous work, we showed that the capturemechanism of a binary asteroid under the co-planar four-body scenario yielded permanentcaptured objects with an orbital shape which is very similar to those of the actual progradeirregular Jovian satellites. By extending our previous study to a 3D case, here we demonstratethat the capture mechanism of a binary asteroid can produce permanent captures of objects byitself which have very similar orbits to irregular Jovian satellites. Some of the captured objectswithout aid of gas drag or other mechanisms present a triplet: semi-major axis, eccentricityand inclination, which is comparable to the already known irregular Jovian objects. © 2013 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.

Among remarkable discoveries concerning propolis, such as antifungal, antiviral, and antioxidant activities, its anti-inflammatory, and mainly its antibacterial, properties deserve special attention when skin wound healing is concerned. Based on this and knowing the distinctive performance of bacterial (BC) membranes on wound healing, in this work it is proposed to demonstrate the potent antimicrobial activity and wound healing properties of a novel propolis containing biocellulose membrane. The obtained propolis/BC membrane was able to adsorb propolis not only on the surface, but also in its interstices demonstrated by scanning electron microscopy, X-ray diffraction, Fourier transform infrared (FT-IR) spectroscopy, and thermogravidimetric assays. Additionally, the polyphenolic compounds determination and the prominent antibacterial activity in the membrane are demonstrated to be dose dependent, supporting the possibility of obtaining propolis/BC membranes at the desired concentrations, taking into consideration its application and its skin residence time. Finally, it could be suggested that propolis/BC membrane may favor tissue repair in less time and more effectively in contaminated wounds. © 2013 Hernane da Silva Barud et al.

Rationale and aim The aims of the Cochrane systematic reviews are to make readily available and up-to-date information for clinical practice, offering consistent evidence and straightforward recommendations. In 2004, we evaluated the conclusions from Cochrane systematic reviews of randomized controlled trials in terms of their recommendations for clinical practice and found that 47.83% of them had insufficient evidence for use in clinical practice. We proposed to reanalyze the reviews to evaluate whether this percentage had significantly decreased. Methods A cross-sectional study of systematic reviews published in the Cochrane Library (Issue 7, 2011) was conducted. We randomly selected reviews across all 52 Cochrane Collaborative Review Groups. Results We analyzed 1128 completed systematic reviews. Of these, 45.30% concluded that the interventions studied were likely to be beneficial, of which only 2.04% recommended no further research. In total, 45.04% of the reviews reported that the evidence did not support either benefit or harm, of which 0.8% did not recommend further studies and 44.24% recommended additional studies; the latter has decreased from our previous study with a difference of 3.59%. Conclusion Only a small number of the Cochrane collaboration's systematic reviews support clinical interventions with no need for additional research. A larger number of high-quality randomized clinical trials are necessary to change the 'insufficient evidence' scenario for clinical practice illustrated by the Cochrane database. It is recommended that we should produce higher-quality primary studies in active collaboration and consultation with global scholars and societies so that this can represent a major component of methodological advance in this context. © 2012 John Wiley & Sons Ltd.

Pulmonary adhesions in dogs are a common sequel after surgical intervention, undermining any interventions. This study aimed to determine in dogs, the efficacy of sodium chloride solution 0.9% with or without dexamethasone in order to prevent adhesions after intercostal thoracotomy. Fifteen dogs were separated into three groups of five animals, A, B and C and underwent thoracotomy in the fifth left intercostal space. Three other dogs were submitted to a previous study. In the dogs of Group A it was performed only a thoracotomy and thoracorraphy; in group B, it was performed a thoracotomy, thoracorraphy and injection into the pleural cavity of isotonic sodium chloride (10ml) and dexamethasone (1mg kg-1). In the dogs of the group C, it was performed the thoracotomy thoracorraphy and injected isotonic sodium chloride (10ml kg-1) into the pleural cavity. After 15 days of thoracotomy, it was performed transdiaphragmatic thoracocospy to determine the presence and score of adhesions between the lung and chest wall. The results demonstrated the presence of adhesions in the majority of group A and reduced or no adhesions in the other groups. For statistical evaluation, it was pplied the chi-square test with significance level of 5% (P≤0.05). The sodium chloride solution 0.9% with or without dexamethasone in the pleural space prevented or reduced lung adhesions after intercostal thoracotomy.

Male goats of reproductive age that were serologically negative for Toxoplasma gondii were selected and distributed according to the following arrangement: (A) one goat infected orally with 2.0 × 105 oocysts; (B) one goat infected subcutaneously with 1.0 × 106 tachyzoites; and (C) one uninfected goat kept as a control. After T. gondii inoculation, 12 non-pregnant female breeder goats that were serologically negative for the main reproductive diseases, especially toxoplasmosis, were synchronized and then exposed to natural mating by the males that had previously been inoculated: five females exposed to natural mating by male A (group GI); five females exposed to natural mating by male B (group GII); and two females exposed to natural mating by the uninfected male C (group GIII). In serum samples obtained from all the female goats before and after natural mating, the presence of antibodies against T. gondii was investigated using the ELISA test. PCR was performed on semen samples, on females and fetal tissues and placenta. Ten out of the 12 females showed specific antibodies against T. gondii after natural mating: five in GI and five in GII. On several dates on which natural mating occurred, T. gondii was identified in semen samples from the infected males, using PCR. Subsequently, after the females had been sacrificed, it was also possible to identify T. gondii in tissue samples from the infected females and from their fetuses, stillbirths and offspring, using PCR. Therefore, these results prove, for the first time, that T. gondii infection can be transmitted sexually from male to female goats. © 2013 Elsevier B.V. All rights reserved.
