Jurisdictional trends in opioid overdose deaths, 1988-96

This report analysed data on opioid overdose mortality between 1988 and 1996 to: examine differences between jurisdictions in the rate of fatal opioid overdose and the rate of increase in overdose; and estimate the proportion of all deaths which were attributed to opioid overdose. Australian Bureau of Statistics (ABS) data were obtained on the number of deaths attributed to opioid dependence (ICD 9 codes 304.0, 304.7) and accidental opioid poisoning (ICD 9 codes E850.0, E850.1). The highest rate of fatal overdose occurred in NSW, followed by Victoria. The standardised mortality rate among other jurisdictions fluctuated quite markedly. While the rate of opioid overdose has increased throughout Australia, the rate of increase has been greater in some of the less-populous states and territories than it has in NSW or Victoria. In 1996, approximately 6.5% of all deaths among people aged 15-24 years and approximately 10% of all deaths among those aged 25-34 were due to opioid overdose. During the interval from 1988 to 1996, the proportion of deaths attributed to opioid overdose increased. From 1988 to 1996, the proportion of deaths attributed to opioid overdose among individuals aged 25-34 years was approximately one-third that attributed to suicide, but this proportion had increased to approximately one-half by 1996. The rate of increase in the proportion of deaths attributed to opioid overdose was higher than the rate of increase in the proportion of deaths attributed to suicide.

Increasingly inequitable distribution of general practitioners in Australia, 1986-96

Objective: To document trends in the distribution of general practitioners (GPs) in Australia between 1986 and 1996, adjusted for community need. Methods: Data on the location of GPs, population size and crude mortality in statistical divisions (SD) were obtained from the Australian Bureau of Statistics Census of Population and Housing in 1986 and 1996. From these data, we calculated measures of distribution equality (number of people sharing each GP in each SD) and distribution equity (number of people sharing each GP divided by the crude mortality rate; the Robin Hood Index), and analysed temporal changes in the distribution of GPs. Results: Nationally the number of people sharing each GP fell 11% from 1,038 in 1986 to 921 in 1996. However, in 41 of 57 SDs (72%, p=0.01) the number of people sharing a GP actually increased over this time, and the average Robin Hood Index across SDs fell from 0.943 to 0.783 (p=0.004), indicating increasingly inequitable distribution. Comparing the Robin Hood index values of all SDs ranked in pairs, the value fell in 53 of 57 (93%, p<0.001) paired SDs over the decade. These patterns demonstrate increasing inequity over the decade. The number of people sharing each GP was consistently and substantially lower in the capital city SDs and the Robin Hood Index values were consistently and substantially higher (overserved) compared with country SDs. Conclusions: Despite there being more GPs per capita in Australia, their distribution became increasingly unequal and inequitable between 1986 and 1996, such that rural and remote areas became increasingly poorly served.

Traditional risk factors for cardiovascular disease in primary antiphospholipid syndrome (APS) when compared with secondary APS: a study with 96 patients

Objective: To evaluate the prevalence of traditional risk factors in patients with primary antiphospholipid syndrome (APS) in comparison to those with systemic lupus erythematosus-secondary APS. Methods: Transversal study of 96 APS patients (Sapporo`s criteria). Demographic and clinical data, cardiovascular risk factors and drug use were investigated. Results: Thirty-nine Primary APS and 57 secondary APS were included. The groups did not differ regarding age (38.5 +/- 9.9 vs. 39.4 +/- 10.5 years, p=0.84) and female gender (84.6 vs. 96.5%, p=0.06), respectively. Arterial events were more observed in primary than secondary APS (59 vs. 36.8%, p=0.04) patients. No difference was seen concerning venous and obstetric events. In regard to traditional risk factors for cardiovascular disease, both groups were comparable related to current or previous smoking, sedentarism, family history for coronary disease, systemic hypertension, diabetes mellitus, overweight and obesity. The frequencies of altered lipid profiles were alike in the two groups, except for a higher prevalence of low HDL-c levels in primary APS group (84.6 vs. 45.5%, p=0.0001). Concerning drug use, no significant differences were observed related to chloroquine and statin use, however the secondary APS patients had a higher rate of prednisone use (10.2 vs. 57.9%, p<0.001) as well as mean dose of corticosteroid (1.5 +/- 5.7 vs. 9.2 +/- 12.5mg/ /day, p=0.0001). Conclusion: Traditional risk factors for cardiovascular disease are present and comparable between patients with primary and secondary APS, except for a high frequency of low HDL-c in primary APS patients.

A Resolução 196/96 e a imposição do modelo biomédico na pesquisa social: dilemas éticos e metodológicos do antropólogo pesquisando o uso de substâncias psicoativas

A Resolução 196/96, instituída pelo Ministério da Saúde com a pretensão de regular os aspectos éticos de qualquer pesquisa "envolvendo seres humanos", ainda não foi plenamente apreciada em suas implicações para os estudos antropológicos. Este artigo ressalta as dificuldades que se apresentam para pesquisas de campo, especialmente as que enfocam atividades ilícitas, tais como o uso de substâncias psicoativas. Esses estudos freqüentemente adotam abordagens etnográficas que pressupõem a ida do pesquisador ao campo e o estabelecimento de relações pessoais entre ele e os sujeitos por meio da participação cotidiana direta em seu meio cultural. Essa metodologia e a condição ilícita das atividades estudadas demandam considerações éticas específicas, às quais as disposições da Resolução 196/96 não atendem. Algumas áreas problemáticas são: (a) a necessidade de aprovação do projeto por um comitê de ética; (b) a dificuldade para obter consentimento informado quando se trabalha com populações ocultas; (c) "acobertamento", "apologia" ou participação em atos ilegais; (d) a dificuldade em fazer crítica social sem ferir interesses de nenhum dos sujeitos estudados; (e) o anonimato em pesquisas que também tenham caráter de registro histórico. As especificidades de diferentes disciplinas reforçam a noção de que comissões de ética devem ser setoriais, sob pena de se avaliar questões diferenciadas segundo padrões somente aplicáveis a algumas delas.

A novel colorimetric assay of beta-D-glucans in basidiomycete strains by alcian blue dye in a 96-well microtiter plate

Basidiomycete strains synthesize several types of beta-D-glucans, which play a major role in the medicinal properties of mushrooms. Therefore, the specific quantification of these beta-D-glucans in mushroom strains is of great biochemical importance. Because published assay methods for these beta-D-glucans present some disadvantages, a novel colorimetric assay method for beta-D-glucan with alcian blue dye was developed. The complex formation was detected by following the decrease in absorbance in the range of 620 nm and by hypsochromic shift from 620 to 606 nm (similar to 14 nm) in UV-Vis spectrophotometer. Analysis of variance was used for optimization of the slope of the calibration curve by using the assay mixture containing 0.017% (w/v) alcian blue in 2% (v/v) acetic acid at pH 3.0. The high-throughput colorimetric assay method on microtiter plates was used for quantification of beta-D-glucans in the range of 0-0.8 mu g, with a slope of 44.15 x 10(-2) and a limit of detection of 0.017 mu g/well. Recovery experiments were carried out by using a sample of Hericium erinaceus, which exhibited a recovery of 95.8% for beta-1,3-D-glucan. The present assay method exhibited a 10-fold higher sensitivity and a 59-fold lower limit of detection compared with the published method with congo red beta-D-glucans of several mushrooms strains were isolated from fruiting bodies and mycelia, and they were quantified by this assay method. This assay method is fast, specific, simple, and it can be used to quantify beta-D-glucans from other biological sources. (C) 2015 American Institute of Chemical Engineers

Criptococose: estudo clínico-epidemiológico, laboratorial e das variedades do fungo em 96 pacientes

Estudo prospectivo foi realizado no Hospital de Clínicas da Universidade Federal de Uberlândia, entre março de 1998 e novembro de 2003, em 96 pacientes com diagnóstico clínico e laboratorial de criptococose, sendo 81,3% portadores de Aids. Cepas de Cryptococcus neoformans foram obtidas de diferentes amostras, sendo 77% em líquido cefalorraquidiano. A var neoformans foi isolada em 89 casos e a var gattii em 7. A meningoencefalite criptocócica (56,3% dos casos), foi a manifestação clínica mais descrita, seguida da fungemia (13,5%). Entre os fatores de risco, a AIDS (81,3%) foi o mais comumente associado à micose. A pesquisa direta do fungo realizada em 121 amostras demonstrou o microrganismo em 98,3%, com cultura (+) em todas. Dos pacientes, 59,4% foram tratados com anfotericina B ou derivados triazólicos, sendo que 72,9% evoluíram para óbito, em particular os portadores de AIDS (62,5%). Atualmente, a criptococose tem sido diagnosticada com muita freqüência em nosso meio e constitui uma das doenças oportunísticas de maior morbidade e mortalidade nos pacientes com AIDS.
