Abstract: asteraceae is one of the most abundant families of the brazilian flora, and it stands out on brazilian red lists due to the large number of endangered and data-deficient species, since it is difficult to define a conservation status for the latter. a comparative analysis of red lists of the brazilian flora focused on the asteraceae is important, so we can assess the true degree of threat to which these plants are subjected faced with increasing environmental degradation. our analysis compared red lists, and pointed out the most threatened species or data-deficient areas, species and genera. the study was based on the first and the current official list of endangered species of the brazilian flora, and the brazilian flora red list of funda??o biodiversitas. species were organized according to the endangered and data-deficient iucn categories. endangered species were also classified according to threat category. the highest numbers of threatened species were observed in the cerrado, in the southeastern region, and in the state of minas gerais, as well as in the genera lychnophora mart., vernonia schreb., and richterago kuntze. the genera aspilia thouars, baccharis l., calea l., eupatorium l., mikania willd., piptocarpha r.br., and senecio l. have the greatest number of data-deficient species. since the current official list does not make clear its threat criteria, the red list of funda??o biodiversitas best portrays the situation of endangered asteraceae species; thus, this analysis provides important information for projects aimed at the conservation of threatened and data-deficient species.

Melhorando o desfecho do transtorno bipolar usando estratégias n?o farmacológicas: o papel da psicoeduca??o
Colom, Francesc;Vieta, Eduard;
Revista Brasileira de Psiquiatria , 2004, DOI: 10.1590/S1516-44462004000700011
Abstract: the present paper addresses the efficacy of psychoeducation and related strategies in bipolar disorders. recently, several randomised clinical trials have shown the efficacy of psychological interventions -namely identification of prodromal signs, cognitive-behavioral therapy, psychoeducation and family-focused interventions- as a prophylactic add-on to medication. all these studies are presented hereby, together with the pioneer studies in the field. there are several topics that every psychoeducational program should include to ensure its usefulness, and they will be summarized in twelve points. roughly, psychoeducation should contain general information about bipolar illness, compliance enhancement elements, teaching on early recognition of relapses and lifestyle regularity issues. nowadays, several treatment guidelines include psychoeducation as a crucial prophylactic tool. clinicians should be aware of this and start performing psychoeducation in their everyday clinical practice.

Abstract: a total of 220 patients with arthropathy were selected in belém, pará between january 1994 and december 2000, and screened for the presence of human parvovirus b19 igm and igg antibodies by enzyme-linked immunosorbent assay (elisa). a subgroup (n = 132) of patients with high levels of antibodies (either igm+/igg+ or igm-/igg+) were examined for the presence of dna by polymerase chain reaction/nested pcr. recent/active infection (detection of igm and/or igg-specific antibodies and presence of viral dna) was identified in 47.7% of the 132 individuals with arthropathy. in our study, women were significantly more affected (59.7%) than men (35.4%) (p = 0.0006). the age group of 11-20 years (84.6%), among female patients, and 21-30 years (42.1%), among male, were those with the highest incidence rates. the analysis of the temporal distribution of b19-associated arthropaties showed a cyclic pattern, with peak incidence rates occuring at 3-5 year intervals. significant diference (p = 0.01) was observed when comparing both the highest (39.0%) and the lowest (11.0%) seropositivity rates for the years of 1995 and 2000, respectively. the interfalangial joints of hands and feet were mostly affected, with 50.0% and 48.0% of cases among both women and men, respectively. in a smaller proportion, other joints such as those of knee, ankle, pulse and shoulder were affected. as for the duration, symptoms lasted 1 to 5 days in 54.0% of the individuals, whereas in 46.0% of them the disease lasted 6-10 days, if considered the subgroup (n = 63) of patients with recent/active infection by parvovirus b19. in our study, joint clinical manifestations occurred symmetrically. our results indicate that b19 may be an important agent of arthropathies in our region, and this underscores the need for specific laboratory diagnosis when treating patients suffering from acute arthropathy, mainly pregnant women.

Abstract: A total of 220 patients with arthropathy were selected in Belém, Pará between January 1994 and December 2000, and screened for the presence of human parvovirus B19 IgM and IgG antibodies by enzyme-linked immunosorbent assay (ELISA). A subgroup (n = 132) of patients with high levels of antibodies (either IgM+/IgG+ or IgM-/IgG+) were examined for the presence of DNA by polymerase chain reaction/nested PCR. Recent/active infection (detection of IgM and/or IgG-specific antibodies and presence of viral DNA) was identified in 47.7% of the 132 individuals with arthropathy. In our study, women were significantly more affected (59.7%) than men (35.4%) (P = 0.0006). The age group of 11-20 years (84.6%), among female patients, and 21-30 years (42.1%), among male, were those with the highest incidence rates. The analysis of the temporal distribution of B19-associated arthropaties showed a cyclic pattern, with peak incidence rates occuring at 3-5 year intervals. Significant diference (P = 0.01) was observed when comparing both the highest (39.0%) and the lowest (11.0%) seropositivity rates for the years of 1995 and 2000, respectively. The interfalangial joints of hands and feet were mostly affected, with 50.0% and 48.0% of cases among both women and men, respectively. In a smaller proportion, other joints such as those of knee, ankle, pulse and shoulder were affected. As for the duration, symptoms lasted 1 to 5 days in 54.0% of the individuals, whereas in 46.0% of them the disease lasted 6-10 days, if considered the subgroup (n = 63) of patients with recent/active infection by parvovirus B19.

Abstract: A total of 730 children aged less than 7 years, attending 8 day-care centers (DCCs) in Belém, Brazil were followed-up from January to December 1997 to investigate the occurrence of human-herpes virus 6 (HHV-6) infection in these institutional settings. Between October and December 1997 there have been outbreaks of a febrile- and -exanthematous disease, affecting at least 15-20% of children in each of the DCCs. Both serum- and- plasma samples were obtained from 401 (55%) of the 730 participating children for the detection of HHV-6 antibodies by enzyme-linked immunosorbent assay (ELISA), and viral DNA amplification through the nested-PCR. Recent HHV-6 infection was diagnosed in 63.8% (256/401) of them, as defined by the presence of both IgM and IgG-specific antibodies (IgM+/IgG+); of these, 114 (44.5%) were symptomatic and 142 (55.5%) had no symptoms (p = 0.03). A subgroup of 123 (30.7%) children were found to be IgM-/IgG+, whereas the remaining 22 (5.5%) children had neither IgM nor IgG HHV-6- antibodies (IgM-/IgG-). Of the 118 children reacting strongly IgM-positive ( > or = 30 PANBIO units), 26 (22.0%) were found to harbour the HHV-6 DNA, as demonstrated by nested-PCR. Taken the ELISA-IgM- and- nested PCR-positive results together, HHV-6 infection was shown to have occurred in 5 of the 8 DCCs under follow-up. Serological evidence of recent infections by Epstein-Barr virus (EBV) and parvovirus B19 were identified in 2.0% (8/401) and 1.5% (6/401) of the children, respectively. Our data provide strong evidence that HHV-6 is a common cause of outbreaks of febrile/exanthematous diseases among children attending DCCs in the Belém area.
Efficacy and safety of aripiprazole in the treatment of bipolar disorder: a systematic review
Konstantinos N Fountoulakis, Eduard Vieta
Annals of General Psychiatry , 2009, DOI: 10.1186/1744-859x-8-16
Abstract: A systematic Medline and repositories search concerning the usefulness of aripiprazole in bipolar disorder was performed, with the combination of the words 'aripiprazole' and 'bipolar'.The search returned 184 articles and was last updated on 15 April 2009. An additional search included repositories of clinical trials and previous systematic reviews specifically in order to trace unpublished trials. There were seven placebo-controlled randomised controlled trials (RCTs), six with comparator studies and one with add-on studies. They assessed the usefulness of aripiprazole in acute mania, acute bipolar depression and during the maintenance phase in comparison to placebo, lithium or haloperidol.Aripiprazole appears effective for the treatment and prophylaxis against mania. The data on bipolar depression are so far negative, however there is a need for further study at lower dosages. The most frequent adverse effects are extrapyramidal signs and symptoms, especially akathisia, without any significant weight gain, hyperprolactinaemia or laboratory test changes.The treatment of bipolar illness started with lithium and Frederik Lange in the late 19th century [1]; later John Cade in 1949 [2-4] and Mogens Schou with Poul Christian Baastrup in the 1970s established its effectiveness [5-10]. Its long-term effects are still a matter of debate [11]. Anticonvulsants are also considered to be useful in the treatment of bipolar illness. In spite of what many clinicians believe, there is no class effect for this group in bipolar disorder, since only valproate carbamazepine and lamotrigine have strong data support. The use and usefulness of antidepressant agents in bipolar disorder (BD) is controversial. Guidelines suggest their cautious use and always in combination with an antimanic agent [12]. This is because antidepressants are believed to induce switching to mania or hypomania [13-16], mixed episodes [17] and rapid cycling, while research suggests that the use of antimanic agents
