ABSTRACT

Objective@#Involuntary admission to psychiatric inpatient care can protect both patients with severe mental illnesses and individuals around them. This study analyzed annual healthcare costs per person for involuntary psychiatric admission and examined categories of mental disorders and other factors associated with mortality. @*Methods@#This retrospective cohort study collected 1 million randomly sampled beneficiaries from the National Health Insurance Database for 2002–2013. It identified and matched 181 patients with involuntary psychiatric admissions (research group) with 724 patients with voluntary psychiatric admissions (control group) through 1:4 propensity-score matching for sex, age, comorbidities, mental disorder category, and index year of diagnosis. @*Results@#Mean life expectancy of patients with involuntary psychiatric admissions was 33.13 years less than the general population. Average annual healthcare costs per person for involuntary psychiatric admissions were 3.94 times higher compared with voluntary admissions. The general linear model demonstrated that average annual medical costs per person per compulsory hospitalization were 5.8 times that of voluntary hospitalization. Survival analysis using the Cox proportional hazards model found no significant association between type of psychiatric admission (involuntary or voluntary) and death. @*Conclusion@#This study revealed no significant difference in mortality between involuntary and voluntary psychiatric admissions, indicating involuntary treatment’s effectiveness.

ABSTRACT

Objective To investigate the epidemiological characteristics of elderly viral pneumonia in Inner Mongolia Autonomous Region from 2018 to 2019 and analyze the pathogenic distribution, and to provide reference for the prevention and treatment of elderly viral pneumonia. Methods A total of 797 elderly patients with viral pneumonia admitted to our hospital from January 2018 to December 2019 were enrolled as the research subjects. All patients were tested for respiratory viral pathogens. According to the test results, the patients were divided into two groups, positive group (n=345) and negative group (n=452). The pathogenic characteristics of patients in the positive group were analyzed. The combined basic diseases, clinical characteristics, laboratory indicators, and distribution of viral pneumonia in different seasons were compared between the two groups. Results Among the 345 patients in the positive group, 319 (92.46%) were infected with single virus, mainly influenza virus (n=221, 64.06%), followed by parainfluenza virus (n=42, 12.17%). There were 26 cases infected with two or more viruses, accounting for 7.54%, mainly influenza virus + parainfluenza virus (n=15, 4.35%). The proportion of patients complicated with diabetes, cardiovascular and cerebrovascular diseases, and malignant tumors in the positive group was significantly higher than that in the negative group (P0.05). The Lym value of the positive group was higher than that of the negative group (P<0.05), while CRP and PCT values were significantly lower than those of the negative group (P<0.05). The incidence rate in the positive group was significantly higher than that in the negative group in winter (P<0.01), and it was significantly lower than that in the negative group in spring (P<0.01). Conclusion In Inner Mongolia Autonomous Region, elderly patients with viral pneumonia are complicated with many basic diseases, but the clinical symptoms are not typical, with high incidence in winter. The infection is mainly caused by influenza virus and parainfluenza virus. Laboratory indicators such as Lym, CRP and PCT can be used to identify viral pneumonia.

ABSTRACT

Objective:To comprehensively analyze the diagnosis and treatment programs and prevention and treatment programs on tratidional Chinese medicine (TCM) for coronavirus disease-2019 (COVID-19), and to provide suggestions for further development of TCM clinical guidelines. Method:Diagnosis and treatment programs on TCM for COVID-19 pneumonia, as well as prevention and treatment programs, clinical practice guidelines and expert consensus, were retrieved till Feb 19, 2020. The information about TCM syndrome differentiation, state of disease, and TCM treatments (decoction and Chinese patent medicines) were extracted and analyzed. Result:A total of 24 TCM programs/guidelines were included containing 23 diagnosis and treatment programs or prevention and treatment programs and one rapid advice guideline. Of the 23 TCM programs, 14 programs described the classification of TCM syndromes and the stages of disease,22 programs described the composition of the TCM decoction; seven programs described how to add and subtract the herbs according to different TCM syndromes,17 programs described the weight/volume of the herbs of TCM decoctions, three programs described the decoction method,six programs described the usage and dosage of TCM decoction, two programs clarified the course of treatment; none of the 23 programs indicated the source of evidence. The TCM treatment within the rapid advice guideline was in reference to the fourth edition of the COVID-19 pneumonia TCM diagnosis and treatment program issued by the National Health Commission. A total of 41 Chinese patent medicines were recommended in 23 programs, of which 12 Chinese patent medicines were off-label recommended. Conclusion:In most TCM programs, TCM decoction and Chinese patent medicines are recommended based on TCM syndrome differentiation in combination with the state of disease, and the dosage of the TCM decoctions are clearly described. Some Chinese patent medicines in the TCM programs are off-label recommended. Expert experience and opinions are valued when developing TCM programs/ guidelines. All of these provide reference for developing TCM programs/guidelines in future.

ABSTRACT

@#Introduction: Cardiovascular disease (CVD) is a group of disease which are related to the heart and its circulations. The main modifiable risk factors of the CVD disease are hypertension, hyperglycemia and obesity. This study aims to evaluate the knowledge, awareness and practice on cardiovascular disease risk factors among Gombak community in Kuala Lumpur. Methods: This was a cross-sectional study using self-administered questionnaire and anthropometric measurement among 388 subjects in Gombak District, Kuala Lumpur. Descriptive data analysis and multivariate binary logistic regression were carried to identify demographic and factors associated. Results: The prevalence of the risk factors was high among study subjects, including obesity (24.2%), hypertension (42.3%) and hyperglycemia (26.8%). More than half (64.4%) of the study subjects having at least one of the risk factor. The multivariate binary logistic model factor illustrated that compare to Malays, Chinese were 37% less likely to have obesity (CPR=0.67; 95% Cl: 0.26-1.69). Gombak district community are more likely to have the knowledge on the CVD risk factor but lack of awareness and poor in practicing the prevention action. The Indian ethnic group was less likely to be aware (APR: 0.33, Cl: 0.05-2.31) and others bumiputera ethnic group were less likely to prevent (APR: 0.58, CI: 0.20-1.65) the risk of CVD. The Chinese ethnic less likely to have the knowledge (APR: 0.88, Cl: 0.35-2.22). Conclusion: Gombak community was more likely to have the knowledge but less likely to be aware and lack of practice of prevention of the risk factors of CVD.

ABSTRACT

Diabetic retinopathy (DR) is one of the most common microangiopathies of diabetes mellitus (DM). It is due to abnormal blood glucose metabolism caused by insufficient insulin secretion or decreased activity. Its pathogenesis is complex, related to multi-gene inheritance and environmental factors. At present, the etiologic study of DR has been gradually deepened at home and abroad, but the epidemiological study of minority DR is lacking. This paper reviews DR's characteristics, ethnic differences and its characteristics in ethnic minority.

ABSTRACT

@#Introduction: Age-related macular degeneration (ARMD) is an ocular degenerative disorder that associated with impairment of central vision. Oxidative stress plays an important role in the pathogenesis of ARMD. The aim of this study was to determine the level of antioxidant enzymes (catalase and glutathione peroxidase) in tears among Malay ARMD patients. Methods: A cross sectional study was conducted between September 2015 and November 2017 among Malay ARMD patients. Schirmer paper was used to collect the tear samples. The level of catalase and glutathione peroxidase level in tears was evaluated using commercially available oxidative stress marker kits. Results: A total of 136 Malay ARMD patients were recruited into the study with 68 controls. Mean tear catalase and glutathione peroxidase levels were significantly lower in ARMD patients (1348.97 SD 109.11 µM and 453.87 SD 41.96 U/L respectively) as compared to the control group (1453.38 SD 38.87 µM and 502.28 SD 34.29 U/L respectively) (P<0.001 and P<0.001 respectively). Late ARMD has lower mean of catalase level in tears as compared to early ARMD (P=0.044). Based on subtypes of neovascular late ARMD, neovascular ARMD has lower mean catalase level in tears compared to idiopathic polypoidal choroidal vasculopathy (IPCV) (P=0.031). Conclusion: This study showed that antioxidant enzyme might play an important factor in the pathogenesis of ARMD.

ABSTRACT

Basaloid follicular hamartoma (BFH) is a rare hamartoma of hair follicle. Clinical presentations may vary but are united by the same histopathological features in the form of folliculocentric basaloid or squamoid cell proliferation in the superficial dermis, which represents malformed and distorted hair follicles. It is important to recognize this entity as its simulant is basal cell carcinoma, a low-grade malignancy. Here, we report a case of localized unilateral BFH in a Blaschkoid distribution on the face of a 14-year-old female.

ABSTRACT

Los trastornos de la conducta alimentaria (TCA), entre los que se encuentran la anorexia nerviosa (AN) y la bulimia nerviosa (BN), presentan una gran relevancia social, económica y sanitaria. Recientemente se ha observado que las alteraciones conductuales típicas de estas pacientes podrían ser explicadas, al menos en parte, por determinados déficits cognitivos. Es por ello que la evaluación neuropsicológica parece ser necesaria para obtener una mayor comprensión de esta clase de trastornos. El objetivo de este estudio fue evaluar si existían diferencias en el funcionamiento neuropsicológico de un grupo de mujeres jóvenes con AN y BN en comparación con otro grupo de mujeres sanas sin TCA (grupo control). Los resultados obtenidos pusieron de manifiesto que las pacientes con TCA presentaron una peor ejecución en la memoria audio-verbal y episódica, una menor flexibilidad cognitiva y una peor capacidad de planificación, en comparación con un grupo de mujeres normativas. No obstante, las pacientes de este estudio se encontraban dentro de los parámetros de normalidad en la memoria visoespacial, en la atención, en la velocidad de procesamiento, en la memoria de trabajo, en la capacidad de inhibición de respuestas automáticas, en la fluidez verbal y en la cognición social. En conclusión, la identificación y caracterización de estas alteraciones cognitivas podría ayudar a identificar nuevos objetivos terapéuticos y desarrollar estrategias de tratamiento más específicas para los pacientes con TCA. De hecho, sería importante desarrollar e implementar programas de rehabilitación cognitiva coadyuvantes a la psicoterapia para este tipo de pacientes.


Eating disorders (ED) such as anorexia nervosa (AN) and bulimia nervosa (BN) have great social, economic, and healthcare relevance. It was recently observed that the typical behavioral alterations of these patients could be explained, at least partly, by certain cognitive deficits. For this reason, neuropsychological evaluations might contribute to better understanding these types of disorders. This study aims to evaluate whether there were differences in the neuropsychological functioning of a group of young women with AN and BN, compared to another group of healthy women without eating disorders (control group). The results obtained showed that patients with eating disorders had worse performance on audio-verbal and episodic memory, less cognitive flexibility, and worse planning capacity than the control group. However, cognitive functioning was unimpaired for visuospatial memory, attention, processing speed, working memory, ability to inhibit automatic responses, verbal fluency, and social cognition. In conclusion, the identification and characterization of these cognitive alterations could help to identify new therapeutic objectives and develop more specific treatment strategies for patients with ED. In fact, it would be important to develop and implement adjuvant cognitive rehabilitation programs alongside the current psychotherapy for these patients.

ABSTRACT

Objective: to characterize the sociodemographic profile of elderly persons with arthritis/rheumatism in relation to gender, as well as to estimate the prevalence and factors associated with functional disability for the performance of instrumental activities of daily living (IADL). Method: a cross-sectional population-based study with a sample of 1,136 elderly persons (≥65 years old) from seven Brazilian municipal regions was carried out. Functional capacity was assessed by the self-reports of the elderly in terms of the performance of IADL, using the Lawton Scale. Differences between the genders, according to sociodemographic variables, were verified by the chi-squared test (p<0.05). The prevalence of inability to perform IADL was calculated and the independent associations were verified through multiple logistic regression. Results: the mean age was 72.4 years, 79.1% of the sample were women, and 45.9% of the elderly with arthritis/rheumatism were dependent for the performance of IADL. Differences were observed between the genders in relation to age, marital status, income and household arrangements (p<0.05). A higher prevalence of disability was observed among older elderly persons, those with no schooling and lower incomes, who lived in multigenerational households and who were frail. In the evaluation of the performance of specific activities, elderly persons with arthritis/rheumatism had greater difficulty taking medication (OR: 1,90; CI 95%: 1.19 - 3.06), after adjusting for gender and age. Conclusion: associations were found between functional disability and sociodemographic variables and frailty. Independence in daily activities such as those evaluated in this study is one of the primary conditions for the well-being of the elderly, even in conditions of frailty or chronic diseases.


Objetivo: caracterizar o perfil sociodemográfico de idosos com artrite/reumatismo em relação ao sexo, bem como estimar a prevalência e os fatores associados à incapacidade funcional para a realização de atividades instrumentais da vida diária (AIVD). Método: estudo transversal de base populacional com amostra de 1.136 idosos (≥65 anos), procedentes de sete municípios brasileiros. A capacidade funcional foi avaliada pelo autorrelato dos idosos quanto à execução das AIVD, pela Escala de Lawton. Diferenças entre os sexos, segundo variáveis sociodemográficas, foram verificadas pelo teste qui-quadrado (p<0,05). Estimou-se a prevalência de incapacidade para a realização das AIVD e as associações independentes foram verificadas por meio de regressão logística múltipla. Resultados: a média de idade foi 72,4 anos, 79,1% eram mulheres e 45,9% dos idosos com artrite/reumatismo apresentaram dependência para a realização das AIVD. Observaram-se diferenças entre os sexos em relação à faixa etária, estado conjugal, renda e arranjo domiciliar (p<0,05). Maior prevalência de incapacidade foi observada entre os mais idosos, naqueles sem escolaridade, com pior renda, nos que viviam em arranjos multigeracionais e com fragilidade. Na avaliação da realização de atividades específicas, os idosos com artrite/reumatismo apresentaram maior dificuldade quanto ao uso de medicação (OR: 1,90; IC95%: 1,19 - 3,06), mesmo após ajuste por sexo e idade. Conclusão: foram encontradas associações entre incapacidade funcional com variáveis sociodemográficas e fragilidade. A independência para a realização de atividades cotidianas como as avaliadas neste estudo torna-se uma das condições primordiais para o bem-estar dos idosos na velhice, mesmo que sob condições de fragilidade ou doenças crônicas.

ABSTRACT

Abstract Objective: This study evaluated the influence of porcelain (VM9, VITA Zahnfabrik, Germany) thickness on the flexural strength and crack propagation in bilayered zirconia systems (YZ, VITA Zahnfabrik, Germany). Material and Methods: Thirty zirconia bars (20.0x4.0x1.0 mm) and six zirconia blocks (12.0x7.5x1.2 mm) were prepared and veneered with porcelain with different thickness: 1 mm, 2 mm, or 3 mm. The bars of each experimental group (n=10) were subjected to four-point flexural strength testing. In each ceramic block, a Vickers indentation was created under a load of 10 kgf for 10 seconds, for the propagation of cracks. Results: The results of flexural strength were evaluated by One-way ANOVA and Tukey's test, with a significance level of 5%. The factor "thickness of the porcelain" was statistically significant (p=0.001) and the l-mm group presented the highest values of flexural strength. The cracks were predominant among the bending specimens with 1 and 2 mm of porcelain, and catastrophic failures were found in 50% of 3-mm-thick porcelain. After the indentation of blocks, the most severe defects were observed in blocks with 3-mm-thick porcelain. Conclusion: The smallest (1 mm) thickness of porcelain on the zirconia infrastructure presented higher values of flexural strength. Better resistance to defect propagation was observed near the porcelain/ zirconia interface for all groups. Higher flexural strength was found for a thinner porcelain layer in a bilayered zirconia system. The damage caused by a Vickers indentation near and far the interface with the zirconia shows that the stress profiles are different.

ABSTRACT

In Aragua state (Venezuela) there are farming communities such as the Tovar municipality that meet geographical and climatic conditions favourable for the development of the fungus Sporothrix schenckii, in which farmer workers would be particularly exposed and at risk of infection and development of sporotrichosis. Accordingly, it was determined the prevalence of this infection in 148 farmers of both sexes from the village "Peñón de Gabante" through the intradermoreaction to esporotrichin. The overall prevalence was 24% and the frequency of infection increased with the age of the farmers, the time working as farmers and it was higher in men (27.6%) than in women (20.8%), reaching values of 39.1% in persons of 50 years and older and 28% in those with more than 10 years occupied in agriculture, although it was independent of these variables. Also, it was found a lower percentage of intradermal positivity (21.8%) in farmers that reported regular use of protective equipment in compare to those whom used it irregularly (27.9%) even though the differences weren't statistically significant. Statistically significant association (p< 0.005) was found between the clinical signs referred by farmers and the intradermopositivity to the esporotrichin, direct contact with plants with thorny branches and/or fruits of prickly shell (p< 0.001) and direct contact with the soil during the process of preparation, fertilization and sowing the crops (p<0.005). These findings suggest that the studied area is endemic to Sporothrix schenckii and farmers found in occupational risk of acquiring this infection.


En el estado Aragua, Venezuela, existen comunidades agrícolas como las del municipio Tovar, que reúnen condiciones geográficas y climáticas favorables para el desarrollo del hongo Sporothrix schenckii, en las que los agricultores estarían particularmente expuestos y a riesgo de adquirir la infección y desarrollar esporotricosis. En conse cuencia, se determinó la prevalencia de esta infección en 148 agricultores de ambos sexos del caserío "Peñón de Gabante", mediante la intradermorreacción a la esporotriquina. La prevalencia fue 24% y la frecuencia de infección incrementó con la edad de los agricultores, el tiempo desarrollando esta labor y fue mayor en hombres (27,6%) que en mujeres (20,8%), alcanzando valores de 39,1% en las personas con edades de 50 años o más y de 28% en aquellos con más de 10 años laborando en la agricultura, aunque resultó independiente de estas variables. Se halló un menor porcentaje de positividad (21,8%) en los agricultores que utilizan en forma regular equipos de protección en comparación con aquellos que lo hacen irregularmente (27,9%), aunque las diferencias no fueron estadísticamente significativas. Se encontró asociación estadísticamente significativa entre la intradermopositividad a la esporotriquina y los signos clínicos relacionados a la esporotricosis (p< 0,005), el contacto directo tanto con plantas de ramas espinosas y/o frutos de cáscara espinosa (p< 0,001) y con el contacto directo con la tierra durante el proceso de preparación, abono y/o siembra de sus cultivos (p< 0,005). Estos hallazgos sugieren que la zona estudiada es endémica para Sporothrix schenckii y los agricultores se encuentran en riesgo ocupacional de contraer esta infección.

ABSTRACT

BACKGROUND/OBJECTIVES: Diet plays an important role in growth and development of children. However, dietary intakes of children living in either rural or urban areas can be influenced by household income. This cross-sectional study examined energy, nutrient and food group intakes of 749 urban children (1-10 years old) by household income status. SUBJECTS/METHODS: Children's dietary intakes were obtained using food recall and record for two days. Diet adequacy was assessed based on recommended intakes of energy and nutrients and food group servings. RESULTS: For toddlers, all nutrients except dietary fiber (5.5 g) exceeded recommended intakes. Among older children (preschoolers and school children), calcium (548 mg, 435 mg) and dietary fiber (7.4 g, 9.4 g) did not meet recommendations while percentage of energy from total fat and saturated fats exceeded 30% and 10%, respectively. The mean sodium intakes of preschoolers (1,684 mg) and school children (2,000 mg) were relatively high. Toddlers in all income groups had similar energy and nutrient intakes and percentages meeting the recommended intakes. However, low income older children had lowest intakes of energy (P < 0.05) and most nutrients (P < 0.05) and highest proportions that did not meet recommended energy and nutrient intakes. For all food groups, except milk and dairy products, all age groups had mean intakes below the recommended servings. Compared to middle and high income groups, low income preschoolers had the lowest mean intake of fruits (0.07 serving), meat/poultry (0.78 serving) and milk/dairy products (1.14 serving) while low income toddlers and school children had the least mean intake of fruits (0.09 serving) and milk/dairy products (0.54 serving), respectively. CONCLUSION: Low socioeconomic status, as indicated by low household income, could limit access to adequate diets, particularly for older children. Parents and caregivers may need dietary guidance to ensure adequate quantity and quality of home food supply and foster healthy eating habits in children.

ABSTRACT

Objective To verify the effects of gender and physical activity on postural sway. Method A cross-sectional study was conducted to analyze upright balance of young men and women between the ages of 20-30, both active and sedentary. Study participants were 60 individuals, who were divided into: active women (n = 15), sedentary women (n = 15), active men (n = 15) and sedentary men (n = 15). The International Physical Activity Questionnaire (IPAQ) short form, was used to evaluate each participant’s level of physical activity. According to the questionnaire, active individuals are those who carry out moderate activity, with an energy expenditure between 3.5 and 6 METs (1 MET: 3.5 ml/kg/min), or vigorous activity, with an energy expenditure above 6 METs, at least three days a week for 20 minutes. To assess control of postural sway, we measured the amplitude and velocity of anteroposterior (AP) and mediolateral (ML) sway in standing position, with their eyes open and closed, with and without foam, on a force platform. Results Comparison between genders revealed that, when compared to sedentary women, sedentary men displayed poorer performance in velocity and amplitude of AP postural control sway with their eyes closed, with and without foam. There were no differences in the amplitude and velocity of ML sway, both with open and closed eyes among groups (p < 0.05). There were no differences when comparing physically active men and women either. Conclusion Sedentary men seem to rely more on vision for maintaining postural control in quiet standing situations with respect to women. .


Objetivo Verificar a relação da oscilação postural entre os sexos e a prática de atividade física. Método Estudo transversal que analisou o equilíbrio semi-estático de homens e mulheres jovens entre 20 e 30 anos, ativos e sedentários. Foram incluídos 60 adultos, que foram divididos em: mulheres ativas (n = 15), mulheres sedentárias (n = 15), homens ativos (n = 15) e homens sedentários (n = 15). Para avaliar o nível de atividade física foi utilizado o Questionário Internacional de Atividade Física (IPAQ) versão curta, que considerou ativos aqueles que realizaram atividade moderada, com gasto de 3,5 a 6 METs (1 MET: 3,5 ml/kg/min), ou vigorosa, com gasto superior a 6 METs, ao menos 3 dias por semana durante 20 minutos. Para avaliação do controle postural, a amplitude e velocidade de oscilação anteroposterior (AP) e mediolateral (ML) foram obtidas por meio de plataforma de força, na posição ortostática, com os olhos abertos e fechados, com e sem a espuma. Resultados Na comparação entre os sexos, os homens sedentários apresentaram pior desempenho de velocidade e amplitude do controle postural AP com os olhos fechados, com e sem espuma, quando comparados com as mulheres sedentárias. Não houve diferenças na amplitude e velocidade de oscilação ML, tanto de olhos abertos quanto fechados entre os grupos (p < 0,05). Também não foram observadas diferenças na comparação entre sexos quando praticantes de exercícios físicos. Conclusão Conclui-se então que, em situação de sedentarismo, o sexo masculino parece mais dependente da visão para a manutenção do controle postural em situações semi-estáticas comparado ao sexo feminino. .

ABSTRACT

Objetivo: Avaliar a influência de diferentes protocolos de cimentação na resistência de união ao push-out de pinos de fibra cimentados adesivamente à dentina radicular bovina. Método: Os canais de 40 dentes bovinos (comprimento: 16 mm) foram preparados (profundidade: 12 mm) utilizando brocas de preparo (Nº 3, RTD). Cada canal teve sua região apical (4 mm comprimento) incluídas em resina acrílica e as raízes foram divididas em quatro grupos, de acordo com os procedimentos de cimentação(n=10): G1-sistema adesivo de frascos múltiplos com condicionamento total + pino de fibra nº 3; G2-sistema adesivo de frascos múltiplos com condicionamento total + pino de fibra nº 1; G3-sistema adesivo de frascos múltiplos com condicionamento total + pino de fibra no1 + pinos de fibra acessórios; G4-Pinos de fibra nº 3 sem condicionamento total nem procedimentos de união na dentina. Com exceção do grupo G4, a dentina radicular foi tratada com sistema adesivo de frascos múltiplos com condicionamento total (All Bond 2/Bisco). O sistema adesivo foi aplicado utilizando microbrush (Dentsply) e o excesso do material foi removido com pontas de papel absorventes. Os pinos de fibra de quartzo (Macro-Lock Illusion/RTD) foram cimentados à dentina radicular utilizando um cimento resinoso dual (Duolink/Bisco) e, em seguida, foram armazenados em água destilada previamente ao teste mecânico (24 h, 37°C). Cada espécime foi cortada em quatro fatias (1,8 mm de espessura), as quais foram submetidas ao ensaio de push-out em máquina de ensaio universal (1mm/min). Os dados (MPa) foram analisados estatisticamente pela análise de variância (ANOVA-1 fator)...


Resultados: Os valores médios (±DP) obtidos após o ensaio de push-outforam: G1- 5,4±1,3 MPa; G2- 4,2±2,4 MPa; G3-4,6±1,5 MPa; G4-3,3±1,7 MPa. Anova demonstrou não haver significância estatística entre os grupos (p=0,0966). A hipótese foi rejeitada. Conclusão: A resistência de união de pinos de fibra à dentina radicular não foi influenciada pelos protocolos de cimentação avaliados...


Objective: To evaluate the influence of different luting protocols on the push-out bond strength of fiber posts cemented to bovine root dentin. Method: Forty bovine root canals (length: 16 mm) were prepared up to 12 mm using #3 (RTD) preparation burs. Each canal had its apical 4 mm embedded in acrylic resin and the roots were assigned to four groups (n=10), according to the cementation procedures: G1: etch-and-rinse multi-bottle adhesive system + #3 fiber post; G2: etch-and-rinse multibottle adhesive system + #1 fiber post; G3: etch-and-rinse multi-bottle adhesive system + #1 fiber post + accessory fiber posts; G4: #3 fiber post without etching and bonding procedures to dentin. Except for G4, root dentin was treated with the etch-and-rinse multi-bottle adhesive system All Bond 2 (Bisco). The adhesive system was applied with a microbrush (Dentsply) and excess material was removed withabsorbent paper points. The quartz fiber posts (Macro-Lock Illusion/RTD) were cemented to the root dentin with a dual-cure resin cement (Duolink/Bisco) and were stored in distilled water (for 24 h at 37 °C) before the mechanical tests. Each sample was cut into four slices (1.8 mm thick) that were subjected to push-out tests in a universaltesting machine (1 mm/min). The data (in MPa) were analyzed statistically by one-way ANOVA. Results: The mean push-out bond strength values (±SD) were: G1: 5.4 ± 1.3 MPa; G2: 4.2 ± 2.4 MPa; G3: 4.6 ± 1.5 MPa and G4: 3.3 ± 1.7 MPa. One-way ANOVA showed no statistically significant differences among the groups. The tested hypothesis was discarded. Conclusion: The push-out bond strength of fiber posts to root dentin was not influenced by the evaluated luting protocols...

ABSTRACT

El objetivo del presente trabajo fue establecer los intervalos de referencia de las determinaciones: glucosa, urea, colesterol, proteínas totales, albúmina, ácido úrico, creatinina, hematocrito y hemoglobina en el Laboratorio Central del Hospital Zonal de Trelew. La población bajo estudio fueron pacientes mayores de 18 años atendidos por consultorio externo entre diciembre de 2008 y marzo de 2009. El estudio fue completado entre marzo y abril de 2011. Las determinaciones se realizaron con un autoanalizador de química clínica Metrolab 2300 plus y un contador hematológico Sysmex 2100. Se comprobó que los valores de las determinaciones se ajustaran a una distribución normal y se realizó el cálculo de los fractiles 0,025 y 0,975 para la obtención del intervalo de referencia (IR) del 95%. En un caso se utilizó transformación logarítmica de los datos y para dos categorías se aplicó el método no paramétrico. Para los valores de referencia inferior y superior se establecieron los intervalos con un 90% de confianza (IC). Los valores de referencia obtenidos fueron: glucosa de 0,74 a 1,07 g/L, urea de 0,19 a 0,51 g/L, colesterol de 1,21 a 2,43 g/L, proteínas totales de 6,45 a 7,99 g/dL, albúmina de 3,62 a 4,61 g/dL, creatinina de 0,57 a 1,10 mg/dL, ácido úrico para el sexo femenino de 18,69 a 51,93 mg/L y para el sexo masculino de 30,50 a 62,92 mg/L, hematocrito para sexo femenino de 37 a 45% y para el sexo masculino de 40 a 50%, hemoglobina para el sexo femenino de 11,70 a 15,17 g/dL y para el sexo masculino de 13,09 a 17,19 g/dL. Los valores de ácido úrico, hematocrito y hemoglobina se separaron por sexo para dar continuidad a la política del laboratorio y de los fabricantes de CAICYTtivos, que consiste en considerar las diferencias existentes entre ambos sexos. Dentro del rango dado por el fabricante se obtuvieron los resultados para glucosa, albúmina y hemoglobina; sobre el mismo, para urea, colesterol, proteínas y ácido úrico y por debajo del mismo para creatinina.


The aim of the present work was to establish the reference intervals of the following determinations, glucose, urea, cholesterol, total proteins, albumin, uric acid, creatinine, hematocrite and hemoglobin in the Central Laboratory of Trelew Zonal Hospital. The population under study was defined as 18-year-old or older patients that came to the laboratory from the ambulatory consulting room since December 2008 to March 2009, and then between March and April 2011. Blood samples were processed with a Metrolab 2300 plus clinical chemistry autoanalyser and a Sysmex 2100 hematological counter. After checking if the result distribution applied to a normal distribution, fractiles 0.025 and 0.975 were calculated to obtain a 95% Reference Interval (RI). In one case, a logarithmic transformation of the results was needed and for two categories a non-parametric method was used. For the upper and lower reference values, the intervals were calculated at 90% confidence (CI) The reference values obtained were; 0.74-1.07 g/L glucose, 0.19-0.51 g/L urea, 1.21-2.43 g/L cholesterol, 6.45-7.99g/dL total proteins, 3.62-4.61 g/dL albumin and 0.57-1.10 mg/dL creatinine, 18.69 - 51.93 mg/L uric acid in women, and 30.50 - 69.92 mg/L in men; 37 - 45% hematocrite in women and 40 - 50% in men; 11.70 - 15.17 g/dL hemoglobin in women and 13.09 - 17.19 g/dL hemoglobin in men. Uric acid, hematocrite and hemoglobin values were calculated according to sex in order to offer concordance with commercial kit and the laboratory policies which consist in considering the significant differences between both sexes. The results obtained for glucose, albumin and hemoglobin were within the reference interval given by the commercial kits; urea, cholesterol, total protein and uric acid were above it; and creatinine reference interval was lower than the reference interval from the commercial kits.


O objetivo do presente trabalho foi estabelecer os intervalos de referencia das determinagóes: glicose, ureia, colesterol, proteínas totais, albumina, ácido úrico, creatinina, hematocrito e hemoglobina no Laboratorio Central do Hospital Zonal de Trelew. A populagao sob estudo foram pacientes de mais de 18 anos atendidos através de consultorio externo entre dezembro do ano 2008 e margo de 2009. O estudo foi completado entre margo e abril de 2011. As determinagóes foram realizadas com um auto-analisador de química clínica Metrolab 2300 plus e um contador hematológico Sysmex 2100. Comprovouse que os valores das determinagóes se ajustaram a uma distribuigao normal e se realizou o cálculo dos quantis 0,025 e 0,975 para a obtengao do intervalo de referencia (IR) de 95%. Num caso foi utilizada transformagao logarítmica dos dados e para duas categorias se aplicou o método nao paramétrico. Para os valores de referencia inferior e superior foram estabelecidos os intervalos com 90% de confianga (IC). Os valores de referencia obtidos foram: glicose de 0,74 a 1,07 gr/L, ureia de 0,19 a 0,51 gr/L, colesterol de 1,21 a 2,43 g/L, proteínas totais de 6,45 a 7,99 gr/dL, albumina de 3,62 a 4,61 gr/dL, creatinina de 0,57 a 1,10 mg/dL, ácido úrico para o sexo feminino de 18,69 a 51,93 mg/L e para o sexo masculino de 30,50 a 62,92 mg/l, hematocrito para sexo feminino de 37 a 45% e para o sexo masculino de 40 a 50%, hemoglobina para o sexo feminino de 11,70 a 15,17 g/dL e para o sexo masculino de 13,09 a 17,19 g/dL. Os valores de ácido úrico, hematocrito e hemoglobina foram separados por sexo para dar continuidade a política do laboratorio e dos fabricantes de reagentes, que consiste em considerar as diferengas existentes entre ambos os sexos. Dentro do intervalo dado pelo fabricante foram obtidos os resultados para glicose, albumina e hemoglobina; superior ao mesmo para ureia, colesterol, proteínas e ácido úrico e inferior ao mesmo para creatinina.
