The Last Missionary to Leave the Temple Should Turn Off the Light Sociological Remarks on the Decline of Japanese ""Immigrant"" Buddhism in Brazil

Empirical data indicate that the so-called ""Buddhism of yellow color"" that is predominantly associated with Japanese ""immigrant"" Buddhism, is constantly in decline in terms of ""explicit"" adherents. After some methodological observations, this article gives an overview of the relevant statistical data. The last part discusses possible reasons for these negative dynamics, referring to causes within Buddhist institutions, the ethnic community, and at the level of the individual.

Hand and ultrasonic instrumentation for orthograde root canal treatment of permanent teeth

Root canal treatment is a frequently performed dental procedure and is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. Removal of the necrotic tissue remnants and cleaning and shaping of the root canal are important phases of root canal treatment. Treatment options include the use of hand and rotary instruments and methods using ultrasonic or sonic equipment. OBJECTIVES: The objectives of this systematic review of randomized controlled trials were to determine the relative clinical effectiveness of hand instrumentation versus ultrasonic instrumentation alone or in conjunction with hand instrumentation for orthograde root canal treatment of permanent teeth. MATERIAL AND METHODS: The search strategy retrieved 226 references from the Cochrane Oral Health Group Trials Register (7), the Cochrane Central Register of Controlled Trials (CENTRAL) (12), MEDLINE (192), EMBASE (8) and LILACS (7). No language restriction was applied. The last electronic search was conducted on December 13th, 2007. Screening of eligible studies was conducted in duplicate and independently. RESULTS: Results were to be expressed as fixed-effect or random-effects models using mean differences for continuous outcomes and risk ratios for dichotomous outcomes with 95% confdence intervals. Heterogeneity was to be investigated including both clinical and methodological factors. No eligible randomized controlled trials were identifed. CONCLUSIONS: This review illustrates the current lack of published or ongoing randomized controlled trials and the unavailability of high-level evidence based on clinically relevant outcomes referring to the effectiveness of ultrasonic instrumentation used alone or as an adjunct to hand instrumentation for orthograde root canal treatment. In the absence of reliable research-based evidence, clinicians should base their decisions on clinical experience, individual circumstances and in conjunction with patients' preferences where appropriate. Future randomized controlled trials might focus more closely on evaluating the effectiveness of combinations of these interventions with an emphasis on not only clinically relevant, but also patient-centered outcomes.

Inconsciente e cotidiano na prática da atenção psicossocial em saúde mental

O objetivo deste artigo é analisar as concepções sobre o inconsciente ligadas ao cotidiano da prática terapêutica de rede, como contribuição à clínica em saúde mental. A pesquisa participante foi realizada em um Centro de Atenção Psicossocial (CAPS) na cidade de São Paulo. Os resultados mostraram as concepções mais frequentes: o inconsciente como inconsciência, o inconsciente como desconhecimento e o inconsciente como método de escuta do sujeito e das relações na instituição. Demonstram uma flexibilidade teórica que pode permitir articulações complexas nas diversas intervenções no cotidiano da equipe referentes às subjetividades e saberes sobre o inconsciente, psicanalíticos ou não. Conclui-se que a elucidação desse saber prático sobre o inconsciente contribui para o aprofundamento dessa temática no campo da reforma psiquiátrica.

Comportamentos em saúde entre idosos hipertensos, Brasil, 2006

OBJETIVO: Estimar as prevalências de comportamentos prejudiciais à saúde e de outros fatores de risco cardiovascular entre idosos com hipertensão auto-referida e comparando-as com de não-hipertensos. MÉTODOS: Foram utilizados dados do sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL), referentes aos 9.038 idosos residentes em domicílios com pelo menos uma linha telefônica fixa nas 26 capitais brasileiras e no Distrito Federal em 2006. RESULTADOS: A prevalência de hipertensão auto-referida foi de 55% (IC 95%: 53;57). A maioria dos hipertensos apresentava concomitância de três ou mais fatores de risco (69%; IC 95%: 67;71). Foram observadas altas prevalências de atividades físicas insuficientes no lazer (88%; IC 95%: 86;89) e do consumo de frutas e hortaliças inferior a cinco porções diárias (90%; IC 95%: 88;90) entre hipertensos, seguidas pela adição de sal aos alimentos (60%; IC 95%: 57;63), consumo habitual de carnes gordurosas (23%; IC 95%: 21;25), tabagismo (9%; IC 95%: 7;10) e consumo abusivo de álcool (3%; IC 95%: 2;4). Essas prevalências foram semelhantes às observadas entre não hipertensos (p >0,05), exceto tabagismo. A prevalência do tabagismo foi menor entre hipertensos (razão de prevalência ajustada [RPA] = 0,75; IC 95%: 0,64;0,89) e as prevalências de sobrepeso (RPA= 1,37; IC 95%: 1,25;1,49), dislipidemia (RPA 1,36; IC 95%: 1,26;1,36) e diabetes (RPA= 1,37; IC 95%: 1,27;1,37) foram mais altas. CONCLUSÕES: Os resultados sugerem que, exceto tabagismo, os comportamentos prejudiciais à saúde entre idosos persistem após o diagnóstico da hipertensão arterial.

Prevalência de excesso de peso e obesidade e fatores associados, Brasil, 2006

OBJETIVO: Estimar a prevalência de excesso de peso e obesidade e fatores associados. MÉTODOS: Foram analisados dados referentes a indivíduos com idade >18 anos entrevistados pelo sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL), realizado nas capitais brasileiras e Distrito Federal em 2006. Para 49.395 indivíduos, o índice de massa corporal (IMC) foi utilizado para identificar excesso de peso (IMC 25-30 kg/m²) e obesidade (IMC >30 kg/m²). Prevalência e razões de prevalência foram apresentadas segundo variáveis sociodemográficas, escolaridade e condição de saúde/comorbidades e auto-avaliação da saúde, estratificadas por sexo. Utilizou-se regressão de Poisson para análises brutas e ajustadas por idade. RESULTADOS: A prevalência de excesso de peso foi de 47% para os homens e 39% para as mulheres, e de obesidade, 11% para ambos os sexos. Observou-se associação direta entre excesso de peso e escolaridade entre homens, e associação inversa entre mulheres. Obesidade foi mais freqüente entre os homens que viviam com companheira e não esteve associada com escolaridade ou cor da pele. As prevalências de excesso de peso e obesidade foram mais altas entre mulheres negras e que viviam com companheiro. A presença de diabetes, hipertensão arterial sistêmica e dislipidemias, bem como considerar sua saúde como regular ou ruim, também foram referidas pelos entrevistados com excesso de peso ou obesidade. CONCLUSÕES: Enquanto cerca de um de cada dois entrevistados foram classificados com excesso de peso, obesidade foi referida por um de cada dez entrevistados. Variáveis socioeconômicas e demográficas, bem como morbidades referidas, foram associadas com excesso de peso e obesidade. Esses resultados foram similares àqueles encontrados em outros estudos brasileiros.

Study of copper electrodeposition mechanism from a strike alkaline bath prepared with 1-hydroxyethane-1,1-diphosphonic acid through cyclic voltammetry technique

Copper strike baths are extensively used in metal plating industry as they present the ability to plate adherent copper layers on less-noble metal substrates such as steel and zinc die castings. However, in the last few years, due to environmental controls and safety policies for operators, the plating industry has been interested in replacing the toxic cyanide copper strike baths with environmentally friendly baths. A broad bibliographic review showed that the published papers, referring to the new nontoxic copper strike baths, are patents, having little or no emphasis focused on electrodeposition mechanisms. Therefore, it was decided to study the copper electrodeposition mechanism from a strike alkaline bath prepared with one of the most nontoxic chelating agents cited in many patents which is the 1-hydroxyethane-1,1-diphosphonic acid, known as HEDP. This acid forms very stable water soluble complexes with Cu(2+) ions, thus cupric sulfate was used for preparing the plating bath. The results obtained through a cyclic voltammetry technique showed that Cu(2+) ion reduction to Cu from an HEDP electrodeposition bath occurs via a direct reduction reaction without a formation of Cu(+) intermediates.

CORRELATION BETWEEN FLOWERING, FRUCTIFICATION AND ENVIRONMENTAL VARIABLES IN Solanum lycocarpum A. St.-Hil, SOLANACEAE

Solanum lycocarpum (lobeira) is a typical and abundant species of brazilian Cerrado, which occupies mainly surrounding disturbed areas. It has interesting characteristics from the point of view of reproductive biology, that probably are favoring the large occupation of habitats by the species. Based on the fact that the species produces flowers and fruit during all the year, the present study had the purpose to verify the association between flower and fruit production with environmental variables (temperature, relative humidity and precipitation), aiming to support future studies referring to reproductive biology and ecology of plant species from Cerrado biome. A population of S. lycocarpum composed of 34 plants in reproductive phase, situated in Morrinhos, south of the State of Goias, Brazil,, was evaluated. All the plants were geographically referenced with a GPS receptor. Observations were made monthly during 13 months (June, 2005 to July, 2006) quantifying open flowers and fruits produced in the intervals between the observations. It was possible suggest high conversion of flowers in fruits. The Spearman rank correlation showed positive correlation of flower number with precipitation and relative humidity. Fruit number was not correlated with the environmental variables.

Patients Receiving Physical Rehabilitation: Records of Sexual Function Before the Introduction of Erectogenic Drugs

The objective of this study is to evaluate the entries associated to the sexual function of patients undergoing physical disability rehabilitation, as well as the course of changes and medical approach through a retrospective review of medical charts. Methods: Medical records referring to the period between July and September, 1998 were evaluated. The data was divided into two groups, records containing physician`s entries on sexual function and/or entries of other health care professionals. The following aspects were investigated: whether complaints were spontaneously voiced by the patient, and whether diagnosis had been reached, with corresponding management. Results: Out of 245 medical records investigated, 17 (6.9%) contained clinical observations on the sexual function; out of those, 14 reached diagnosis. Twelve records (4.9%) had information by non-medical healthcare professionals. Out of 17 entries by doctors, 16 referred to male patients, which was found to be significant (p = 0.0202). Conclusions: Records for the sexual function of patients undergoing physical rehabilitation are scarce. In this population, the sexual function of male patients had more extensive investigation on the part of physicians when compared to other health care professionals.

Automatic versus manual pressure support reduction in the weaning of post-operative patients: a randomised controlled trial

Introduction Reduction of automatic pressure support based on a target respiratory frequency or mandatory rate ventilation (MRV) is available in the Taema-Horus ventilator for the weaning process in the intensive care unit (ICU) setting. We hypothesised that MRV is as effective as manual weaning in post-operative ICU patients. Methods There were 106 patients selected in the postoperative period in a prospective, randomised, controlled protocol. When the patients arrived at the ICU after surgery, they were randomly assigned to either: traditional weaning, consisting of the manual reduction of pressure support every 30 minutes, keeping the respiratory rate/tidal volume (RR/TV) below 80 L until 5 to 7 cmH(2)O of pressure support ventilation (PSV); or automatic weaning, referring to MRV set with a respiratory frequency target of 15 breaths per minute (the ventilator automatically decreased the PSV level by 1 cmH(2)O every four respiratory cycles, if the patient`s RR was less than 15 per minute). The primary endpoint of the study was the duration of the weaning process. Secondary endpoints were levels of pressure support, RR, TV (mL), RR/TV, positive end expiratory pressure levels, FiO(2) and SpO(2) required during the weaning process, the need for reintubation and the need for non-invasive ventilation in the 48 hours after extubation. Results In the intention to treat analysis there were no statistically significant differences between the 53 patients selected for each group regarding gender (p = 0.541), age (p = 0.585) and type of surgery (p = 0.172). Nineteen patients presented complications during the trial (4 in the PSV manual group and 15 in the MRV automatic group, p < 0.05). Nine patients in the automatic group did not adapt to the MRV mode. The mean +/- sd (standard deviation) duration of the weaning process was 221 +/- 192 for the manual group, and 271 +/- 369 minutes for the automatic group (p = 0.375). PSV levels were significantly higher in MRV compared with that of the PSV manual reduction (p < 0.05). Reintubation was not required in either group. Non-invasive ventilation was necessary for two patients, in the manual group after cardiac surgery (p = 0.51). Conclusions The duration of the automatic reduction of pressure support was similar to the manual one in the postoperative period in the ICU, but presented more complications, especially no adaptation to the MRV algorithm.

A New Periapical Index Based on Cone Beam Computed Tomography

The purpose of this study was to evaluate a new periapical index based on cone beam computed tomography (CBCT) for identification of apical periodontitis (AP). The periapical index proposed in this study (CBCTPAI) was developed on the basis of criteria established from measurements corresponding to periapical radiolucency interpreted on CBCT scans. Radiolucent images suggestive of periapical lesions were measured by using the working tools of Planimp software on CBCT scans in 3 dimensions: buccopalatal, mesiodistal, and diagonal. The CBCTPAI was determined by the largest lesion extension. A 6-point (0-5) scoring system was used with 2 additional variables, expansion of cortical bone and destruction of cortical bone. A total of 1014 images (periapical radiographs and CBCT scans) originally taken from 596 patients were evaluated by 3 observers by using the CBCTPAI criteria. AP was identified in 39.5% and 60.9% of cases by radiography and CBCT, respectively (P<.01). The CBCTPAI offers an accurate diagnostic method for use with high-resolution images, which can reduce the incidence of false-negative diagnosis, minimize observer interference, and increase the reliability of epidemiologic studies, especially those referring to AP prevalence and severity.
