Uso do prontuário eletrônico na assistência pré-natal às portadoras de diabetes na gestação

Objetivo Apresentar e validar um registro eletrônico de saúde (RES) multifuncional para atendimento ambulatorial a portadoras de endocrinopatias na gestação e comparar a taxa de preenchimento de informações de saúde com o prontuário convencional. Métodos Desenvolvemos um RES denominado Ambulatório de Endocrinopatias na Gestação eletrônico (AMBEG) para registro sistematizado das informações de saúde. O AMBEG foi utilizado para atendimento obstétrico e endocrinológico de gestantes acompanhadas no ambulatório de endocrinopatias na gestação na maternidade referência em gestação de alto risco na Bahia, no período de janeiro de 2010 a dezembro de 2013. Aleatoriamente foramselecionadas 100 pacientes atendidas como AMBEG e 100 pacientes atendidas comprontuário convencional comregistro em papel e comparou-se a taxa de preenchimento de informações clínicas. Resultados Foram realizados 1461 atendimentos com o AMBEG: 253, 963 e 245 respectivamente, admissões, consultas de seguimento e puerpério. Eram portadoras de diabetes 77,2% e sendo 60,1% portadoras de diabetes pré-gestacional. O AMBEG substituiu, satisfatoriamente, o prontuário convencional. O percentual de informações clínicas registradas em ambos os prontuários foi significativamente maior no AMBEG: queixas clínicas (100 versus 87%, p < 0,01), altura uterina (89 versus 75%, p = 0,01), ganho de peso total (91 versus 40%, p < 0,01) e dados específicos sobre o diabetes (dieta, esquema de insulina, controle glicêmico e manejo de hipoglicemias) revelando diferença significativa (p < 0,01). A possibilidade de exportar dados clínicos para planilhas facilitou e agilizou a análise estatística de dados. Conclusões O AMBEG é uma ferramenta útil no atendimento clínico a mulheres portadoras de endocrinopatias na gestação. A taxa de preenchimento de informações clínicas foi superior à do prontuário convencional.

Assistência religiosa no sistema socioeducativo: a visão dos operadores do direito

O artigo discute o direito à assistência religiosa dos adolescentes privados de liberdade no estado Rio de Janeiro. A partir da identificação de várias formas de violação desse direito no sistema socioeducativo fluminense, foi organizada uma pesquisa com os atores do sistema judiciário, a saber: juízes, defensores públicos, promotores e um representante do Conselho Estadual de Direitos da Criança e do Adolescente. O foco da pesquisa foi identificar a concepção de assistência religiosa desses atores e verificar se os mesmos tinham domínio da legislação. A pesquisa foi realizada em 2010 e demonstrou que os membros do judiciário contatados se encontravam pouco preparados para lidar com o direito à assistência religiosa dos adolescentes.

Long-lasting mnemotropic effect of substance P and its N-terminal fragment (SP1-7) on avoidance learning

We investigated the long-lasting effect of peripheral injection of the neuropeptide substance P (SP) and of some N- or C-terminal SP fragments (SPN and SPC, respectively) on retention test performance of avoidance learning. Male Wistar rats (220 to 280 g) were trained in an inhibitory step-down avoidance task and tested 24 h or 21 days later. Immediately after the training trial rats received an intraperitoneal injection of SP (50 µg/kg), SPN 1-7 (167 µg/kg) or SPC 7-11 (134 µg/kg). Control groups were injected with vehicle or SP 5 h after the training trial. The immediate post-training administration of SP and SPN, but not SPC, facilitated avoidance behavior in rats tested 24 h or 21 days later, i.e., the retention test latencies of the SP and SPN groups were significantly longer (P<0.05, Mann-Whitney U-test) during both training-test intervals. These observations suggest that the memory-enhancing effect of SP is long-lasting and that the amino acid sequence responsible for this effect is encoded by its N-terminal part

N-terminal amino acids of bovine alpha interferons are relevant for the neutralization of their antiviral activity

The structure-function relationship of interferons (IFNs) has been studied by epitope mapping. Epitopes of bovine IFNs, however, are practically unknown, despite their importance in virus infections and in the maternal recognition of pregnancy. It has been shown that recombinant bovine (rBo)IFN-alphaC and rBoIFN-alpha1 differ only in 12 amino acids and that the F12 monoclonal antibody (mAb) binds to a linear sequence of residues 10 to 34. We show here that the antiviral activities of these two IFNs were neutralized by the F12 mAb to different extents using two tests. In residual activity tests the antiviral activity dropped by more than 99% with rBoIFN-alphaC and by 84% with rBoIFN-alpha1. In checkerboard antibody titrations, the F12 mAb titer was 12,000 with rBoIFN-alphaC and only 600 with rBoIFN-alpha1. Since these IFNs differ in their amino acid sequence at positions 11, 16 and 19 of the amino terminus, only these amino acids could account for the different neutralization titers, and they should participate in antibody binding. According to the three-dimensional structure described for human and murine IFNs, these amino acids are located in the alpha helix A; amino acids 16 and 19 of the bovine IFNs would be expected to be exposed and could bind to the antibody directly. The amino acid at position 11 forms a hydrogen bond in human IFNs-alpha and it is possible that, in bovine IFNs-alpha, the F12 mAb, binding near position 11, would disturb this hydrogen bond, resulting in the difference in the extent of neutralization observed.

A high-copy T7 Escherichia coli expression vector for the production of recombinant proteins with a minimal N-terminal His-tagged fusion peptide

We report here the construction of a vector derived from pET3-His and pRSET plasmids for the expression and purification of recombinant proteins in Escherichia coli based on T7 phage RNA polymerase. The resulting pAE plasmid combined the advantages of both vectors: small size (pRSET), expression of a short 6XHis tag at N-terminus (pET3-His) and a high copy number of plasmid (pRSET). The small size of the vector (2.8 kb) and the high copy number/cell (200-250 copies) facilitate the subcloning and sequencing procedures when compared to the pET system (pET3-His, 4.6 kb and 40-50 copies) and also result in high level expression of recombinant proteins (20 mg purified protein/liter of culture). In addition, the vector pAE enables the expression of a fusion protein with a minimal amino-terminal hexa-histidine affinity tag (a tag of 9 amino acids using XhoI restriction enzyme for the 5'cloning site) as in the case of pET3-His plasmid and in contrast to proteins expressed by pRSET plasmids (a tag of 36 amino acids using BamHI restriction enzyme for the 5'cloning site). Thus, although proteins expressed by pRSET plasmids also have a hexa-histidine tag, the fusion peptide is much longer and may represent a problem for some recombinant proteins.

N-terminal-pro-brain natriuretic peptide, but not brain natriuretic peptide, is increased in patients with severe obesity

Elevated body mass index (BMI) has been reported as a risk factor for heart failure. Prevention of heart failure through identification and management of risk factors and preclinical phases of the disease is a priority. Levels of natriuretic peptides as well as activity of their receptors have been found altered in obese persons with some conflicting results. We investigated cardiac involvement in severely obese patients by determining N-terminal-pro-brain natriuretic peptide (NT-proBNP) and brain natriuretic peptide (BNP) and attempting to correlate the levels of these peptides in serum and plasma, respectively, with BMI, duration of obesity, waist circumference, and echocardiographic parameters. Thirty-three patients with severe obesity (mean BMI: 46.39 kg/m², mean age: 39 years) were studied. The control group contained 30 healthy age-matched individuals (BMI: <25 kg/m², mean age: 43 years). The t-test and Spearman correlation were used for statistical analysis. Log-NT-proBNP was significantly higher (P = 0.003) in obese patients (mean 1.67, 95% CI: 1.50-1.83 log pg/mL) compared to controls (mean: 1.32, 95% CI: 1.17-1.47 log pg/mL). The Log-NT-proBNP concentration correlated with duration of obesity (r = 0.339, P < 0.004). No difference was detected in the Log-BNP concentration (P = 0.63) of obese patients (mean: 0.73, 95% CI: 0.46-1.00 log pg/mL) compared to controls (mean: 0.66, 95% CI: 0.51-0.81 log pg/mL). NT-proBNP, but not BNP, is increased in severely obese patients and its concentration in serum is correlated with duration of obesity. NT-proBNP may be useful as an early diagnostic tool for the detection of cardiac burden due to severe obesity.

N-terminal prohormone brain natriuretic peptide (NT-proBNP) as a noninvasive marker for restrictive syndromes

Constrictive pericarditis (CP) and restrictive cardiomyopathy share many similarities in both their clinical and hemodynamic characteristics and N-terminal prohormone brain natriuretic peptide (NT-proBNP) is a sensitive marker of cardiac diastolic dysfunction. The objectives of the present study were to determine whether serum NT-proBNP was high in patients with endomyocardial fibrosis (EMF) and CP, and to investigate how this relates to diastolic dysfunction. Thirty-three patients were divided into two groups: CP (16 patients) and EMF (17 patients). The control group consisted of 30 healthy individuals. Patients were evaluated by bidimensional echocardiography, with restriction syndrome evaluated by pulsed Doppler of the mitral flow and serum NT-proBNP measured by immunoassay and detected by electrochemiluminescence. Spearman correlation coefficient was used to analyze the association between log NT-proBNP and echocardiographic parameters. Log NT-proBNP was significantly higher (P < 0.05) in CP patients (log mean: 2.67 pg/mL; 95%CI: 2.43-2.92 log pg/mL) and in EMF patients (log mean: 2.91 pg/mL; 95%CI: 2.70-3.12 log pg/mL) compared with the control group (log mean: 1.45; 95%CI: 1.32-1.60 log pg/mL). There were no statistical differences between EMF and CP patients (P = 0.689) in terms of NT-proBNP. The NT-proBNP log tended to correlate with peak velocity of the E wave (r = 0.439; P = 0.060, but not with A wave (r = -0.399; P = 0.112). Serum NT-proBNP concentration can be used as a marker to detect the presence of diastolic dysfunction in patients with restrictive syndrome; however, serum NT-proBNP levels cannot be used to differentiate restrictive cardiomyopathy from CP.

The N-terminal 33 amino acid domain of Siva-1 is sufficient for nuclear localization

Siva-1 induces apoptosis in multiple pathological processes and plays an important role in the suppression of tumor metastasis, protein degradation, and other functions. Although many studies have demonstrated that Siva-1 functions in the cytoplasm, a few have found that Siva-1 can relocate to the nucleus. In this study, we found that the first 33 amino acid residues of Siva-1 are required for its nuclear localization. Further study demonstrated that the green fluorescent protein can be imported into the nucleus after fusion with these 33 amino acid residues. Other Siva-1 regions and domains showed less effect on Siva-1 nuclear localization. By site-mutagenesis of all of these 33 amino acid residues, we found that mutants of the first 1-18 amino acids affected Siva-1 nuclear compartmentalization but could not complete this localization independently. In summary, we demonstrated that the N-terminal 33 amino acid residues were sufficient for Siva-1 nuclear localization, but the mechanism of this translocation needs additional investigation.

Estudo epidemiológico da doença renal crônica terminal no oeste do Paraná: uma experiência de 878 casos atendidos em 25 anos

INTRODUÇÃO: A incidência e prevalência dos pacientes em fase final da doença renal crônica (DRC) continuam a crescer em todo o mundo. O transplante renal continua tendo preferência na terapia renal substitutiva, mas, dada a limitada oferta de doadores de órgãos, terapias dialíticas são as modalidades mais realizadas. OBJETIVOS: Avaliar um registro de pacientes admitidos para terapia renal substitutiva no período de 1984 a 2009, em um único Centro. MÉTODOS: Este é um estudo epidemiológico retrospectivo. Foram analisadas as características demográficas e clínicas, incidência, principal doença renal de base, modalidades dialíticas, mortalidade e causas de óbitos. Para comparar as variáveis, foram utilizados o teste do qui-quadrado, teste t de Student, ANOVA e teste de Tukey. Curvas de Kaplan-Meier foram utilizadas para estimar a sobrevida dos pacientes. Um valor de p < 0,05 foi considerado estatisticamente significativo. RESULTADOS: No período compreendido, 878 pacientes foram admitidos em diálise. A média de idade dos pacientes foi 47,0 ± 16,2 anos, 549 (62,5%) eram do sexo masculino e 712 (81,1%) eram brancos. As principais causas da DRC foram a hipertensão, encontrada em 351 (40,0%) pacientes; nefropatia diabética, em 174 (19,8%); e glomerulonefrite crônica, em 180 (20,5%) pacientes. A principal modalidade dialítica foi a hemodiálise. A taxa de mortalidade em um ano foi de 10,4%. As causas mais comuns de morte foram as cardiovasculares, em 126 (34,6%) pacientes. CONCLUSÕES: Neste estudo esta coorte de pacientes apresentou baixa mortalidade. A doença cardiovascular permanece a principal causa de óbito na população com doença renal crônica em estágio terminal. Triagem para doença cardiovascular é altamente recomendada para esses pacientes.
