Abstract:

The importance-performance analysis method (IPA) is used in market research in order to measure the level of customer satisfaction. The aim of this study was to evaluate and highlight the use of IPA as a management tool to measure quality of dental services. We suggest that this method can be easily implemented in a dental educational setting, as a performance outcome measure that includes patient input. The study was conducted in a dental service through a valid questionnaire, SERVQUAL. This instrument explores levels of service quality perceived by patients. It was conducted in four companies in Brazil in 2011 (derived from different industry segments; two from textiles, one from hospital care and the other from the manufacturing industry) in two States (S?o Paulo and Minas Gerais). These companies were covered by the same dental managed care organization which contracted with independent dentists to provide care. The study was divided into two stages: the first, in which beneficiaries answered the questionnaire prior to receiving dental treatment, and the second when the same beneficiaries answered after completing their dental treatment. Data obtained from SERVQUAL generated graphs

that were used to characterize the IPA matrix using several dimensions of care. The Assurance Dimension had the highest average in both expectation and perception. The Reliability dimension showed the value of the most negative GAP among the dimensions, and the best value occurred in the Responsiveness dimension. The IPA tool may be effective in Dental Medicine since it highlights the key points to be improved in the delivery of dental services in a clinical setting.

Abstract: homocysteine, formed from hepatic methionine, is metabolized through the pathways of demethylation and transsulfuration. its plasmatic and urinary values reflect the cell synthesis. its determination after fasting and increased infusion of methionine shows the differences of these two metabolic pathways, mainly when it is related to genetic diseases. hyperhomocysteinemia has been associated with a higher risk of vascular thrombotic events. several authors suggest a causal relationship between these events independently of other risk factors for vascular diseases. decrease in plasmatic homocysteine to normal levels is followed by a significant reduction on the incidence of vascular thrombotic events. the correlation between the liver and homocysteine is becoming more important because of the recent findings that alterations of lipoproteins and methionine clearance are common in patients with hepatocellular and canalicular chronic liver disease. the treatment of hiperhomocysteinemia is based on the supplementation of folic acid and vitamins b6 and b12.

Abstract:


The cardiopulmonary resuscitation (CPR) persists as the best practice to maintain cerebral and coronary perfusion after cardiac arrest. Due to the chest compressions and ventilation maneuvers during resuscitation, there are common complications reported. Abdominal organs injuries occur in approximately 30% of patients, although studies show that they are under diagnosticated. The aim of this article is to report a case of massive digestive hemorrhage by gastric laceration after cardiopulmonary resuscitation, due to the event severity and rare clinic diagnostic. A 75-year-old Caucasian man suffered a sudden malaise and cardiac arrest and transferred to an Emergency Unit (EU). The set of measures recommended by Advanced Cardiac Life Support (ACLS) was performed. Despite no resistance to the passage of nasogastric survey and spontaneous healing of fresh blood exteriorization, an endoscopy showed ulcers in gastric notch with clots adhered and active blood. There was no track record of liver or gastrointestinal diseases on this patient, identifying a gastric laceration after cardiopulmonary resuscitation. The mechanism by which the gastric laceration after CPR occurred is uncertain. Nevertheless, some precipitating factors are considered such as positioning of the patient during CPR, ideal point of compressions and ventilation pressure. In conclusion, this event is rare with a hard diagnostic however that could be avoided and minimized with preventive measures.

Abstract: the corn plants were evaluated with different phosphate fertilizer sources and aluminum (al) concentrations in a sandy substrate. a totally randomized experiment design was set up with two corn plants in the pots containing 2 kg of a sandy substrate, two phosphate sources (triple super phosphate - tsp or arad phosphate - ap) and four al concentrations. when al concentrations increased, ph (cacl2) substrate values decreased. there was an increase in the calcium and phosphorus contents in the sandy substrates that received the tsp and ap sources. the calcium, magnesium, phosphorus, and potassium concentrations of the corn plant's shoot were higher in the tsp than without p and ap sources. when the al concentration increased, the concentration values of the former elements decreased. the dry mass production of the corn plants responded positively to p sources. as the al concentration increased, the dry mass values decreased significantly in the tsp source.

Abstract: over the past 50 years, the understanding of the deteriorative changes involved in the progression of heart failure (hf), initially described as resulting from changes in salt and fluid retention, or changes in hemodynamic parameters, have changed significantly. recently, several studies conducted in hf patients showed altered plasma (or serum) levels of pro-inflammatory cytokines, such as tumor necrosis factor α (tnf-α), interleukins 1, 6, and 18, and cardiotropin-1, among other inflammatory markers. these changes were independent of hf etiology, suggesting a common pathogenic pathway. in response to these new findings, interventions to prevent and/or reduce these inflammatory changes have been proposed. the aerobic training-induced cardiovascular benefits of physical exercises performed at intensities ranging from mild to moderate have been previously reported. moreover, it has been shown that moderate aerobic physical training seems to be able to modulate, in the presence of an abnormal chronic inflammatory condition, the overexpression of pro-inflammatory cytokines, soluble adhesion molecules, chemoattractant factors and oxidative stress. altogether, these data indicate a possible anti-inflammatory effect induced by physical training. therefore, this review aims to assess the role of physical training as an alternative non-pharmacological adjuvant to be administered in some pathological conditions in which tnf-α chronic changes are predominant, as in hf. the "anti-inflammatory effect" induced by physical training seems to be primarily mediated by il-10.

Abstract: maghemite (g-fe2o3) is the most usually found ferrimagnetic oxide in red basalt-derived soils. the variable degrees of ionic substitution of fe3+ for different metals (e.g. ti4+, al3+, mg2+, zn2+, and mn2+) and non-metals in the maghemite structure influence some cristallochemical features of this iron oxide. in this study, synthetic zn-substituted maghemites were prepared by co-precipitation in alkaline aqueous media of feso4.7h2o with increasing amounts of znso4.7h2o to obtain the following sequence of fe3+ for zn2+ substitutions: 0.0, 0.025, 0.05, 0.10, 0.15, 0.20, and 0.30 mol mol-1. the objective of this work was to evaluate the cristallochemical alterations of synthetic zn-substituted maghemites. the dark black synthetic precipitated material was heated to 250 °c during 4 h forming a brownish maghemite that was characterized by chemical analysis as well as x ray diffraction (xrd), specific surface area and mass-specific magnetic susceptibility. the isomorphic substitution levels observed were of 0.0013, 0.0297, 0.0590, 0.1145, 0.1764, 0.2292 and 0.3404 mol mol-1, with the formation of a series of maghemites from fe2zn0o3 to fe(1.49)zn(0.770)o3 . the increase in fe3+ for zn2+ substitution, [zn mol mol-1] increased the dimension a0 of the cubic unit cells of the studied maghemites according to the regression equation: a0 = 0.8343 + 0.02591zn (r2 = 0.98). on the other hand, the mean crystallite dimension and mass-specific magnetic susceptibility of the studied maghemites decreased with increasing isomorphic substitution.
