Tempo de validade dos exames pré‐operatórios normais para uma reintervenção cirúrgica e o impacto nos desfechos pós‐operatórios

Background and objective

There are few data defining the period of time in which preoperative tests can be considered valid. The purpose of this study was to determine the likelihood of changes in the results of preoperative tests previously normal in relation to time, and the impact of these changes on postoperative outcomes.

MC3T3‐E1 Cells Behavior on Surfaces Bombarded by Argon Ions in Planar Cathode Discharge

To evaluate the effect of topography in nanoscale, titanium surfaces were bombarded by argon ions (a chemically inert gas), in an atmosphere of plasma. The effects of surface parameters on morphology, adhesion, proliferation, and MC3T3‐E1 preosteoblasts differentiation were analyzed. Nontreated (smooth) surfaces were used as a control. The levels of average roughness (Ra) observed in bombarded and smooth titanium surfaces were of 95 and 14 nm, respectively. The wettability increased on treated surfaces. The number of attached cells (30 and 60 min) was significantly higher on the bombarded surface. The cell proliferation after 3 and 7 days was also significantly higher on the ion‐bombarded surface. In addition, the ALP activity and expression of osteocalcin were higher in cells grown on the treated surface. The results showed that bombardment with argon ions increased the roughness and the wettability of the Ti surface, promoting a significant increase in the adhesion, proliferation, and differentiation of preosteoblasts.     

Essential oils rich in monoterpenes are unsuitable as additives to boar semen extender

Despite the development of efficient boar semen extenders, there is still room for improvement of new formulas using new molecules that could increase fertilisation outcomes and substitute cryoprotectants and antibiotics. The goal of this work was to evaluate if the essential oils from the leaves of Myrrhinium atropurpureum and Cymbopogon citratus are suitable as additives in boar semen extender. The major compounds found in the essential oils from M. atropurpureum were 1,8‐cineole (37.37%) and terpinolene (19.18%); and geranial (49.8%) and neral (33.24%) in essential oil of C. citratus. The addition of 1% and 0.1% of both essential oils to extended semen had immediate spermicidal effects (p < 0.05). Lower concentrations were tested and no cytotoxic effect was observed when M. atropurpureum essential oil was added at 0.001%. Differently, essential oil from C. citratus reduced sperm motility, membrane functionality and integrity and mitochondrial membrane potential even in concentrations as low as 0.001%. Also, addition of essential oils in low concentrations had no inhibitory effect against Escherichia coli and Pseudomonas aeruginosa growth. We conclude that the essential oils from C. citratus and M. atropurpureum, rich in monoterpenes, are cytotoxic to swine spermatozoa, therefore unsuitable as semen extender additives.     

Postoperative complications and patient satisfaction: does payer status have an impact?

Background

Patient demographics and outcomes may influence patient satisfaction. We aim to investigate the relationship between postoperative complications and survey-based satisfaction in the context of payer status.

Methods

Institutional data were used to identify major complication occurrence and linked to patient satisfaction surveys. The impact of complication occurrence on satisfaction was investigated and stratified by payer status.

Results

In all, 1,597 encounters were identified with an 18% major complication rate. Satisfaction scores in specific domains were significantly more likely to be above the median for patients without complications (P < .01) and for payer status Medicaid/low income (P < .05). In sensitivity analyses, we found no significant interactions among payer status, complications, and satisfaction scores.

Conclusions

Significant differences exist for individual satisfaction survey domains between patients with and without major postoperative complications and by payer status. Payer status was not found to have an impact on the intersection of major complications and patient satisfaction.     

Fusarium Solani: a causative agent of skin and nail infections

Fusarium spp are non-dermatophytic hyaline moulds found as saprophytes and plant pathogens. Human infections are probably a result of various precipitating predisposing factors of impaired immune status. Immunocompetent individuals of late are also vulnerable to various unassuming saprophytic and plant pathogens. To stress the need to identify correctly and institute appropriate antifungal therapy in newly emerging human fungal infectious agents. Repeated mycological sampling of the skin and nails of the suspected fungal infection were processed as per the standard format including direct microscopy and fungal culture on Sabouraud's dextrose agar. The fungus was isolated as Fusarium solani. Fusarium is an important plant pathogen and soil saprophyte. Infection is acquired by direct inoculation or inhalation of spores. It is associated with a variety of diseases like keratitis, onychomycosis, eumycetoma, skin lesions and disseminated diseases.     

Behavioral Research on Headaches: a Coded Bibliography

SYNOPSIS
This coded bibliography aims to include all behavioral headache research published to date. Four hundred and forty references have been found predominantly through Psychological Abstracts and the journal Headache . Each article has been coded according to seven variables which describe the subject sample, and thirteen variables which describe the focus or topic of the study. Each reference preceded by the reference number, subject code, number of subjects in the study, and the topic code. Examples of subject codes are the types of headache the subjects were suffering from; and examples of topic codes are studies focussing on psychophysiological mechanisms, biofeedback training and personality. A table of reference numbers lists the articles pertaining to each topic starting with those including both tension headache and migraine subjects, followed by those including only tension headache subjects, then migraine only, and finally, 'other'. Hence, this table enables rapid retrieval of references according to the focus of the study and characteristics of the subject sample.     

Determination of 51Cr and 241Am X-ray and gamma-ray emission probabilities per decay

In this paper results of X-ray and gamma-ray emission probabilities per decay of ⁵¹Cr and ²⁴¹Am are presented. The measurements were carried out by means of HPGe planar and REGe spectrometers. The activity of ⁵¹Cr and ²⁴¹Am samples was determined in a 4πβ?γ coincidence counting system. The HPGe spectrometers were calibrated in a well defined geometry by means of ⁵⁴Mn, ⁵⁵Fe, ⁵⁷Co, ¹³³Ba, ¹⁵²Eu, ^166mHo and ²⁴¹Am sources, previously standardized in a 4πβ?γ coincidence system. The MCNP Monte Carlo code was used for simulation of the REGe spectrometer calibration curve, for the selected geometry, and compared with the experimental curve. The experimental results were compared with data from literature.
