RESUMO

This study aims to evaluate the quality of salted sun-dried meat from young bulls (Nellore cattle) fed with a diet containing 0.0, 0.5, 1.0 and 1.5% of lauric acid in the total dry matter (DM). Thirty-two Nellore bulls with initial body weight of 368 ± 32 kg were used. A linear decrease (p < 0.05) in pH and protein content of the salted sun-dried meat was observed with the inclusion of lauric acid. The moisture, ash, lipid, collagen content, water-holding capacity, cooking loss, color indexes (L*, a*, b*, C*), and shear force were not affected. Lipid oxidation at 7 days of storage increased linearly in the salted sun-dried meat. Most of the fatty acid composition of the salted sun-dried meat from the semimembranosus muscle of young bulls was not influenced (p > 0.05) by the lauric acid inclusion in the bulls' diet. However, there was a linear increase (p < 0.05) in the SFA lauric acid (C12:0), PUFAn-3 EPA (C20:5n − 3) and DHA (C22:6n − 3), and a quadratic increase in the PUFAn-6 arachidonic (C20:4n − 6) due to lauric acid addition from palm kernel oil in the diet. There was a liner increase (p < 0.05) in the total ∑PUFA, ∑n − 6, ∑n − 3 contents of salted sun-dried meat from the semimembranosus muscle of young bulls and the h:H health index of the level of lauric acid inclusion in bull's diet. In contrast, the thrombogenicity health index (TI) and ∑n − 6:∑n − 3 ratio content in salted sun-dried meat from the semimembranosus muscle of young bulls presented a linear decrease (p < 0.05) due to lauric acid addition in the bulls' diet. Lauric acid (C12:0) inclusion up to 1.5% in the diet of young Nellore bull improved the fatty acid composition of the salted sun-dried meat, increasing EPA, DHA, n − 6 and n − 3, TI, and h:H indexes, which are associated with a better lipid quality of meat products, and further improves tenderness at the highest concentration.

RESUMO

BACKGROUND: Treatment-free survival (TFS) in chronic myeloid leukemia (CML) is a new goal. This prospective study aims to evaluate imatinib discontinuation's feasibility and safety in patients with deep molecular response MR4 (BCR-ABL1 < 0.01 % IS). METHODS: Study was approved by the ethical committee and registered at Clinicaltrials.gov (NCT03239886). Incluision criteria were: age ≥ 18y, chronic phase, first-line imatinib for 36 months, MR4 for 12 months, no previous transplant or resistance. Imatinib was resumed when two samples confirmed the loss of MMR. The primary endpoint was molecular recurrence-free survival (MRFS) at 24 months. Lymphocyte subpopulations were counted in peripheral blood before discontinuation. RESULTS: 31 patients were included from Dec/2016 until Oct/2017. Median age was 54years, 58 % male, 58 % low Sokal, 65 % b3a2 transcripts, and 61 % were in MR4.5. Imatinib therapy's median time was 9.7y (3-14.9 y), median time of MR4 was 6.9y (1.6-10.3y). MRFS at 24 months was 55 % (95 % CI 39-75). Thirteen patients relapsed, 46 % after six months of discontinuation, and all patients recovered MMR. Median time to recover MMR was one month. MR4.5 was the only factor associated with MRFS. NK cells proportion at baseline was lower in patients with only MR4 who relapsed after discontinuation. CONCLUSION: With a median duration of sustained MR4 above five years, as recommended by most TKI discontinuation guidelines, the TFS was similar to previous studies. Only MR4.5 was associated with lower risk of relapse. Further studies are needed to evaluate whether patients with only MR4 and low NK cell levels are suitable for discontinuation.

RESUMO

HIV test-seeking behavior among blood donors has been observed worldwide and may pose a threat to the safety of the blood supply. We evaluated current test-seeking motivations and prior alternative HIV testing experiences among blood donors in São Paulo, Brazil. All candidate or potential blood donors were consecutively approached and recruited to participate in the study upon presentation at Fundação Pró-Sangue Hemocentro, the largest blood bank in Brazil. Participants were recruited between August 2012 and May 2013 after they were screened for donor eligibility. Questionnaires were administered through audio computer-assisted self-interview. Among 11,867 donors, 38 % previously tested for HIV apart from blood donation, of whom 47.7 % tested at public facilities and 2.7 % acknowledged getting tested for HIV as the primary reason for donating. Dissatisfaction with prior alternative testing experience was reported by 2.5 % of donors. Current test-seeking motivation was associated with dissatisfaction with prior alternative testing experience and testing at a public alternative facility. The most common reasons for dissatisfaction were too long of a wait to get tested and for results, counseling was too long, lack of privacy, and low confidence in the equipment and accuracy of the test. Lack of awareness about the availability of free and confidential public HIV testing services as well as dissatisfaction with past HIV testing and counseling experiences motivate some individuals to test at blood banks. Test-seeking behavior among blood donors may be best addressed by improving alternative testing programs, particularly with respect to time delays, privacy and perceptions about test accuracy. Educational campaigns on safe blood donation and HIV testing for diagnosis, risk counseling and referral to care are also needed for the general public and for health care providers.

RESUMO

BACKGROUND: In a randomized controlled trial (RCT) in a blood bank in São Paulo, we tested the hypotheses that offering client-centered human immunodeficiency virus (HIV) counseling and testing to blood donors would: 1) reduce the risk of HIV contamination in the blood supply by diverting higher-risk, test-seeking donors away from donation and 2) increase return for results and referrals to care. STUDY DESIGN AND METHODS: We randomly selected weeks between August 2012 and May 2013 when donors were offered HIV counseling and testing (n = 6298), leaving usual procedure weeks as control (n = 5569). RESULTS: Few candidate donors chose HIV testing (n = 81, 1.3%). There was no significant difference in herpes simplex virus Type 2 (HSV-2) prevalence (a marker of sexual risk) among donors during intervention weeks compared to control (10.4% vs. 11.1%, p = 0.245). No donor choosing testing was HIV infected, and there was no difference in HSV-2 prevalence between testers and donors (9.9% vs. 10.4%, p = 0.887). Returning for positive results did not differ between testers and donors (three of three vs. 58 of 80, p = 0.386). A higher proportion of donors acknowledged that HIV testing was a strong motivation to donate during intervention weeks compared to control (2.6% vs. 2.0%, p = 0.032). CONCLUSION: The evidence of our RCT is that offering HIV counseling and testing at the time of donation would not change the risk of contamination in the blood supply, nor improve results disclosure and referral to care.

RESUMO

This work describes the phytochemical study of the extracts from aerial parts of Tibouchina candolleana as well as the evaluation of the antimicrobial activity of extracts, isolated compounds, and semi-synthetic derivatives of ursolic acid against endodontic bacteria. HRGC analysis of the n-hexane extract of T. candolleana allowed identification of b-amyrin, a-amyrin, and b-sitosterol as major constituents. The triterpenes ursolic acid and oleanolic acid were isolated from the methylene chloride extract and identified. In addition, the flavonoids luteolin and genistein were isolated from the ethanol extract and identified. The antimicrobial activity was investigated via determination of the minimum inhibitory concentration (MIC) using the broth microdilution method. Amongst the isolated compounds, ursolic acid was the most effective against the selected endodontic bacteria. As for the semi-synthetic ursolic acid derivatives, only the methyl ester derivative potentiated the activity against Bacteroides fragilis.

RESUMO

O linfoma de Hodgkin (LH) é uma neoplasia do tecido linfóide de excelente prognóstico, porém, aproximadamente 15 por cento dos pacientes em estádios precoces e 35 por cento dos em estádios avançados progridem após o tratamento inicial. O transplante autólogo de medula óssea ou de células-tronco periféricas (ATMO) é o tratamento de escolha nesses casos. Nosso estudo tem como objetivo avaliar o tipo de tratamento utilizado, a taxa de resposta e a sobrevida de pacientes recidivados ou refratários ao ATMO. De 38 pacientes com LH submetidos a ATMO entre abril de 1996 e novembro de 2005, foram avaliados 17 que apresentaram recidiva/refratariedade ao ATMO. Nesses casos, o tratamento de resgate foi individualizado, a depender das condições clínicas de cada um, sendo constituído usualmente de drogas citotóxicas não utilizadas previamente. Após o ATMO, dez (59 por cento) dos 17 pacientes obtiveram remissão completa, um (6 por cento) remissão parcial e seis (35 por cento) foram refratários. Em 14 dos 17 pacientes foi instituída quimioterapia de resgate com diversos esquemas no momento da recidiva/refratariedade após ATMO; um paciente foi tratado com radioterapia exclusiva e dois foram a óbito antes de qualquer terapia. Observamos uma taxa de resposta global de 57,4 por cento (IC95 por cento: 23,2 - 90,7 por cento). A mediana da sobrevida livre de progressão foi de 19 meses e a mediana de sobrevida global foi de 32 meses. Apesar do LH recidivado/refratário ao ATMO não ser curável com os quimioterápicos atualmente disponíveis, os pacientes apresentaram longa sobrevida, com freqüentes exacerbações da doença.


Hodgkin's lymphoma (HL) is a lymphoid malignancy with excellent prognosis, however nearly 15 percent of the patients in early stages and 35 percent in advanced stages have progressive disease after initial treatment. Autologous bone marrow or hematopoietic stem cell transplantation (ABMT) are the treatments of choice in these cases. This report presents the therapeutic approach and the outcome of HL patients who experience relapse after or are refractory to ABMT. Of 38 patients with LH who underwent ABMT between April 1996 and November 2005, 17 presented with relapsed/refractory disease and were included in this analysis. In these cases, the choice of rescue therapy varied upon the clinical conditions of each patient and was based on previously unused chemotherapy agents. After ABMT, 10 (59 percent) of the 17 patients were in complete remission, one (6 percent) in partial remission and six (35 percent) were refractory. Fourteen of the 17 patients received different schemes of rescue therapy at the time of ABMT failure, one patient was treated exclusively with radiotherapy and two died before any treatment. We observed an overall response rate of 57.4 percent (95 percent CI: 23.2 - 90.7 percent). The median progression-free survival was 19 months and the median overall survival was 32 months. Despite ABTM, relapsed/refractory LH can not be cured with currently available chemotherapeutic agents, the patients had long survival times with frequent exacerbations of the diseas.

RESUMO

Este artigo analisa como o suporte social é percebido pelo pai durante a hospitalização do filho prematuro e da mulher na UTI. A história oral foi usada como referencial metodológico. Os dados foram coletados por meio de entrevistas gravadas com seis pais em forma de narrativa e analisados à luz da Teoria de Suporte Social de Vaux. Os pais reconheceram a dedicação da equipe na execução dos cuidados, tanto ao bebê como à mulher. Por outro lado, identificaram uma falta de apoio desses profissionais relacionada a comunicação inadequada. Esse estudo nos reporta à necessidade de repensar a prática assistencial na enfermagem.


This article analyses how social support is perceived by a parent (father) during the hospital stay of his premature newborn son and his wife in an intensive care unit (ICU). The methodological reference was the history presented orally. Data was collected through recorded interviews with six parents (fathers) as narratives, and analyzed using Vaux´s social support theory. Parents (fathers) recognized the dedication and care given to babies and mothers by the health team. On the other hand, they pointed to lack of adequate communication given by these professionals. This study underlines the need to rethink nursing care.

RESUMO

OBJETIVO: Avaliar e comparar indicadores básicos de saúde infantil entre menores de 5 anos residentes na área urbana do município de Rio Grande (RS) em 1995 e 2004. MÉTODOS: Foram realizados dois estudos transversais de base populacional nessa cidade. Entrevistadores previamente treinados aplicaram questionários padronizados em domicílios com crianças menores de 5 anos. Foram investigados: renda familiar, escolaridade materna, tipo de construção da moradia, disponibilidade de sanitário, água encanada, rede de esgotos e eletrodomésticos. Sobre as crianças, investigou-se número de consultas e idade de início do pré-natal, tipo e atendimento ao parto, padrão de amamentação e dieta, morbidade e utilização de serviços de saúde. As crianças foram pesadas e medidas para altura/comprimento. A comparação de freqüências nos dois estudos foi feita através do teste do qui-quadrado. RESULTADOS: Foram estudadas 395 crianças em 1995 e 384 em 2004. Nesse período, houve melhorias no tipo de construção de moradia, na presença de sanitário com descarga, na disponibilidade de água encanada e no padrão e duração da amamentação. A ocorrência de diarréia diminuiu, enquanto as taxas de cobertura vacinal básica, monitoração do crescimento, posse do cartão de saúde e de notificação do peso ao nascer aumentaram. Houve piora no poder aquisitivo das famílias e no número médio de consultas pré-natais realizadas. A prevalência de obesidade infantil aumentou em 92 por cento, enquanto a ocorrência de desnutrição praticamente não se modificou. CONCLUSÕES: A comparação dos indicadores de saúde no período entre os dois estudos mostrou, além de melhorias na maioria dos indicadores avaliados, substancial aumento na prevalência de obesidade infantil.


OBJECTIVE: To evaluate and compare basic indicators of the health of children under 5 years old in the urban area of Rio Grande, RS, Brazil, for 1995 and 2004. METHODS: Two cross-sectional population studies were carried out in the city. Interviewers were previously trained and applied standardized questionnaires during visits to families with children under 5 years old. The following variables were investigated: family income, maternal education, type of construction of home (wooden/masonry etc.), availability of toilet, running water, sewage system and domestic appliances. Data collected on the children themselves included number of antenatal consultations and age at first antenatal, type of delivery and medical care received during delivery, breastfeeding and dietary patterns, morbidity and health services utilization. Children were weighed and measured for height/length. Comparisons of frequencies between the two datasets were made using the chi-square test. RESULTS: In 1995, 395 children were studied and in 2004 there were 384. During the intervening period improvements had taken place in type of construction, number of homes with flush toilet, the availability of running water and in breastfeeding pattern and duration. The frequency of diarrhea reduced, while rates of basic vaccination coverage, growth monitoring, patients in possession of their own medical cards and reporting of birth weights all increased. There was a deterioration in families' purchasing power and in the mean number of antenatal consultations. The prevalence of childhood obesity increased by 92 percent, while the incidence of malnutrition remained practically unchanged. CONCLUSIONS: Comparing health indicators from the two periods revealed that, in addition to improvements in the majority of the indicators assessed, there had been a substantial increase in the prevalence of childhood obesity.
