Reabilitação cardíaca home-based monitorizada à distância por tecnologias de informação e comunicação: Uma revisão sistemática

Introdução: Cada vez mais a Reabilitação Cardíaca (RC) tem um início precoce no tratamento e nas necessidades do paciente no sentido de promover a sua autonomia e responsabilização pela recuperação, através de uma abordagem multidisciplinar. Os programas home-based e a inclusão das tecnologias de informação e comunicação são soluções atrativas para o aumento da participação dos doentes selecionados e inclusão de grupos de doentes atualmente sub-representados. Objetivos: Sistematizar a evidência científica atual sobre a efetividade dos programas de reabilitação cardíaca home-based com controlo á distância através da aplicação de novas tecnologias, comparando-a com a reabilitação centre-based/hospital-based, ao nível da adesão e da atividade física. Métodos: Este trabalho consiste numa revisão sistemática da literatura publicada entre 2007 e 2014, através de uma pesquisa em diferentes bases de dados eletrónicas científicas (Elsevier – Science Direct, PEDro, PubMed, Scielo Portugal e B-on) com as palavras-chave: reabilitação cardíaca, home-based, centre-based, hospital-based, reabilitação exercise-based, telemonitorização, smartphone, internet, atividade física, em todas as combinações possíveis. Os estudos foram analisados independentemente por dois revisores quanto aos critérios de inclusão e qualidade dos estudos. Resultados: Dos 101 estudos identificados, apenas dez foram incluídos. Considerando a escala da PEDro, quatro estudos obtiveram um score 5, quatro, um score de 6, e 2 com um score de 7 em 10. Os estudos foram realizados em adultos com idades compreendidas entre os 18 e os 80 anos. Os programas de intervenção dividiram-se em planeamento de atividade física e em autogestão. Todos os programas de exercício físico conduziram a um aumento da capacidade de exercício e consequente, maior controlo de fatores de risco. Pelos níveis de adesão aos PRC home-based e pelos resultados positivos de diferentes parâmetros em relação a reabilitação centre-based/hospital-based é notável a efetividade da telemonitorização baseada em casa. Conclusão: A telemonitorização domiciliária constitui um elemento fundamental para a solução de numerosos problemas destes doentes, tornando-se em métodos simples e de fácil funcionamento para haver sucesso nas taxas de adesão. Com efeito, a utilização das tecnologias de informação e de comunicação permite uma prestação e gestão eficazes dos cuidados de saúde no domicílio.

PRETERM BIRTH AND FETAL GROWTH RESTRICTION IN HIV-INFECTED BRAZILIAN PREGNANT WOMEN

Introduction: Maternal HIV infection and related co-morbidities may have two outstanding consequences to fetal health: mother-to-child transmission (MTCT) and adverse perinatal outcomes. After Brazilian success in reducing MTCT, the attention must now be diverted to the potentially increased risk for preterm birth (PTB) and intrauterine fetal growth restriction (IUGR). Objective: To determine the prevalence of PTB and IUGR in low income, antiretroviral users, publicly assisted, HIV-infected women and to verify its relation to the HIV infection stage. Patients and Methods: Out of 250 deliveries from HIV-infected mothers that delivered at a tertiary public university hospital in the city of Vitória, state of Espírito Santo, Southeastern Brazil, from November 2001 to May 2012, 74 single pregnancies were selected for study, with ultrasound validated gestational age (GA) and data on birth dimensions: fetal weight (FW), birth length (BL), head and abdominal circumferences (HC, AC). The data were extracted from clinical and pathological records, and the outcomes summarized as proportions of preterm birth (PTB, < 37 weeks), low birth weight (LBW, < 2500g) and small (SGA), adequate (AGA) and large (LGA) for GA, defined as having a value below, between or beyond the ±1.28 z/GA score, the usual clinical cut-off to demarcate the 10th and 90th percentiles. Results: PTB was observed in 17.5%, LBW in 20.2% and SGA FW, BL, HC and AC in 16.2%, 19.1%, 13.8%, and 17.4% respectively. The proportions in HIV-only and AIDS cases were: PTB: 5.9 versus 27.5%, LBW: 14.7% versus 25.0%, SGA BW: 17.6% versus 15.0%, BL: 6.0% versus 30.0%, HC: 9.0% versus 17.9%, and AC: 13.3% versus 21.2%; only SGA BL attained a significant difference. Out of 15 cases of LBW, eight (53.3%) were preterm only, four (26.7%) were SGA only, and three (20.0%) were both PTB and SGA cases. A concomitant presence of, at least, two SGA dimensions in the same fetus was frequent. Conclusions: The proportions of preterm birth and low birth weight were higher than the local and Brazilian prevalence and a trend was observed for higher proportions of SGA fetal dimensions than the expected population distribution in this small casuistry of newborn from the HIV-infected, low income, antiretroviral users, and publicly assisted pregnant women. A trend for higher prevalence of PTB, LBW and SGA fetal dimensions was also observed in infants born to mothers with AIDS compared to HIV-infected mothers without AIDS.

KPC-PRODUCING Serratia marcescens IN A HOME-CARE PATIENT FROM RECIFE, BRAZIL

SUMMARY In this brief communication we describe the occurrence of a KPC-producing Serratia marcescensisolate in a home-care patient from Recife, Brazil. The blaKPC, blaSPM, blaIMP, blaVIMblaOXA, blaCTX-M, blaSHV, blaTEM and blaGES genes were investigated by Polymerase Chain Reaction (PCR) and DNA sequencing. The isolate was positive for blaKPC-2 and blaTEM-1 and was resistant to aztreonam, cefepime, cefotaxime, imipenem, meropenem, gentamicin, ciprofloxacin and cefazidime, and susceptible only to amikacin, tigecycline and gatifloxacin. This is the first report in Brazil of KPC-producing S. marcescens clinical isolate outside of a hospital environment. Caregivers should be alert for the presence of this isolate in the community setting.

ANTIFUNGAL ACTIVITY OF Cymbopogon nardus (L.) Rendle (CITRONELLA) AGAINST Microsporum canis FROM ANIMALS AND HOME ENVIRONMENT

Dermatophytosis is a common zoonosis in urban centers. Dogs and cats have played an important role as its disseminators. Environmental decontamination is essential for the prevention of its propagation to humans and animals. However, sanitizers or disinfectants with antifungal activity, currently available, have high toxicity. The present study evaluated the in vitro effects of an extract of citronella (Cymbopogon nardus) on 31 Microsporum canis isolates from animals and home environments. Susceptibility tests were performed based on document M38-A2 (2008) of the Clinical and Laboratory Standards Institute with modifications for natural products. Although susceptibility variation was observed between the fungus tested, the concentrations that inhibited the growth of 50 and 90% of the microorganisms were low (19.5 and 78 µg/mL, respectively). Thus, this citronella extract showed potent fungistatic and fungicide activities against M. canis isolated from animals and home environments. Therefore, it could be an alternative for dermatophytosis prophylaxis in the home environment.

DENGUE DURING PREGNANCY: ASSOCIATION WITH LOW BIRTH WEIGHT AND PREMATURITY

The aim of this study was to evaluate the effects of dengue virus infection during pregnancy and its correlation with low birth weight, prematurity, and asphyxia. A non-concurrent cohort study reveals the association of dengue during pregnancy with prematurity and low birth weight, when birth occurred during the maternal-fetal viremia period (p = 0.016 and p < 0.0001, respectively).

Planeamento integrado de alta hospitalar nos idosos

RESUMO: O planeamento da alta hospitalar representa um momento crucial no internamento de pessoas idosas, que muitas vezes regressam ao domicílio com necessidades complexas ao nível dos cuidados. No entanto, não existe um planeamento de alta universal, tornando prioritário o desenvolvimento de estratégias nesse sentido. Após revisão de literatura foi formulado um modelo de análise, com as dimensões e indicadores críticos para a problemática em estudo. Objectivo: Este estudo teve como objectivo analisar as repercussões que um planeamento de alta hospitalar integrado pode ter na satisfação e no bem-estar dos doentes e famílias, tendo impacto ao nível da redução das reincidências hospitalares. Métodos: Foi seleccionada uma amostra no Serviço de Medicina 1B do Centro Hospitalar Lisboa Norte, dividida aleatoriamente em dois grupos. O grupo controlo teve um planeamento de alta de acordo com os padrões habituais, enquanto o grupo experimental foi alvo de um planeamento de alta integrado, com enfoque na informação e clarificação nos cuidados pós alta, e com recurso à entrega de um documento de orientação para a alta. Foi realizado um contacto telefónico de follow-up um mês após a alta, para realização de um questionário telefónico. Resultados: Os participantes do grupo experimental revelaram ter tendência para estar mais bem preparados para a alta hospitalar e regresso ao domicílio, valorizando de forma mais positiva o processo de internamento e alta, bem como a auto-percepção de bem-estar. Conclusões: Apesar da limitação da dimensão da amostra, os resultados apontam no sentido de que os procedimentos do planeamento integrado de alta hospitalar têm um impacto positivo ao nível da satisfação e sentimento de bem-estar global dos idosos no regresso ao domicílio, influenciando na redução das reincidências hospitalares.------------ ABSTRACT: The hospital discharge planning represents a crucial moment in the hospitalization of the elderly, whom very often return home with very complex caring needs. However, there is no universal discharge planning as such, thus becoming mandatory to develop planning strategies. Upon review of reference literature, an investigational model was developed, that features the key indicators and dimensions of the subject matter. Aim: The aim of this study was to analyze how hospital discharge planning promotes the satisfaction and well-being of patients and their families, reducing the number of hospital readmissions. Methods: A sample population was selected from the 1B Internal Medicine Service of Centro Hospitalar Lisboa Norte, which was divided in two random groups. The control group experienced a standard discharge, whereas the experimental group underwent a planned integrated discharge, which focused on the clarification of the post-discharge caring needs. A discharge guidance document was produced and handed to the patients. One month after discharge, a follow-up telephone call was made. Results: The experimental group turned out to be better prepared for hospital discharge and to return home, positively valuing hospitalization and hospital discharge, as well as their perception of their own well-being. Conclusions: The integrated hospital discharge planning had a positive impact on patient satisfaction and global well-being upon their return, and effectively reduced the number of hospital readmissions.

Nursing Home-Acquired Pneumonia Presenting at the Emergency Department

Nursing home-acquired pneumonia (NHAP) is one of the most common infections arising amongst nursing home residents, and its incidence is expected to increase as population ages. The NHAP recommendation for empiric broad-spectrum antibiotic therapy, arising from the concept of healthcare-associated pneumonia, has been challenged by recent studies reporting low rates of multidrug-resistant (MDR) bacteria. This single center study analyzes the results of NHAP patients admitted through the Emergency Department (ED) at a tertiary center during the year 2010. There were 116 cases, male gender corresponded to 34.5 % of patients and median age was 84 years old (IQR 77-90). Comorbidities were present in 69.8 % of cases and 48.3 % of patients had used healthcare services during the previous 90 days. In-hospital mortality rate was 46.6 % and median length-of-stay was 9 days. Severity assessment at the Emergency Department provided CURB65 index score and respective mortality (%) results: zero: n = 0; one: n = 7 (0 %); two: n = 18 (38.9 %); three: n = 26 (38.5 %); four: n = 30 (53.3 %); and five; n = 22 (68.2 %); and sepsis n = 50 (34.0 %), severe sepsis n = 43 (48.8 %) and septic shock n = 22 (72.7 %). Significant risk factors for in-hospital mortality in multivariate analysis were polypnea (p = 0.001), age ≥ 75 years (p = 0.02), and severe sepsis or shock (p = 0.03) at the ED. Microbiological testing in 78.4 % of cases was positive in 15.4 % (n = 15): methicillin-resistant Staphylococcus aureus (26.7 %), Pseudomonas aeruginosa (20.0 %), S. pneumoniae (13.3 %), Escherichia coli (13.3 %), others (26.7 %); the rate of MDR bacteria was 53.3 %. This study reveals high rates of mortality and MDR bacteria among NHAP hospital admissions supporting the use of empirical broad-spectrum antibiotic therapy in these patients.

The Effect of Long-Chain Polyunsaturated Fatty Acids Intake During Pregnancy on Adiposity of Healthy Full-Term Offspring at Birth

OBJECTIVE: The adjusted effect of long-chain polyunsaturated fatty acid (LCPUFA) intake during pregnancy on adiposity at birth of healthy full-term appropriate-for-gestational age neonates was evaluated. STUDY DESIGN: In a cross-sectional convenience sample of 100 mother and infant dyads, LCPUFA intake during pregnancy was assessed by food frequency questionnaire with nutrient intake calculated using Food Processor Plus. Linear regression models for neonatal body composition measurements, assessed by air displacement plethysmography and anthropometry, were adjusted for maternal LCPUFA intakes, energy and macronutrient intakes, prepregnancy body mass index and gestational weight gain. RESULT: Positive associations between maternal docosahexaenoic acid intake and ponderal index in male offspring (β=0.165; 95% confidence interval (CI): 0.031-0.299; P=0.017), and between n-6:n-3 LCPUFA ratio intake and fat mass (β=0.021; 95% CI: 0.002-0.041; P=0.034) and percentage of fat mass (β=0.636; 95% CI: 0.125-1.147; P=0.016) in female offspring were found. CONCLUSION: Using a reliable validated method to assess body composition, adjusted positive associations between maternal docosahexaenoic acid intake and birth size in male offspring and between n-6:n-3 LCPUFA ratio intake and adiposity in female offspring were found, suggesting that maternal LCPUFA intake strongly influences fetal body composition.

Pattern of acquisition of rotavirus antibody in children followed up from birth to the age of three years

Nine hundred and forty-eight serum samples from 83 children living in Belem, Brazil, collected'within their first three years of life, were testedfor the presence of group- specific rotavirus-antibody by an enzyme-linked immunosorbent assay (ELISA) blocking-test. Passively transferred maternal antibody lasted about two and half months; subsequentely, low levels of rotavirus antibody started to appear at seven months, reaching a peak at eleven months of age. From one year onwards positivity gradually increased, reaching highest values at 34 months of life. Individual responses were examined in sera from 61 children who were followed up since birth to three years of age: 38 (62,3%) ofthem developed a long-term immunity following first infection; eleven (18.0%) children developed a short-term immunity after first infection by rotavirus; seven (11.5%) had no antibody response within their first three years of life; and 5 (8.2%) showed positive antibody response from birth to three years old.

O impacto do perfil do utente da USF durante o seu internamento

RESUMO - Introdução: Através da elaboração do presente projeto de investigação pretendeu-se analisar o que poderá influenciar o custo total de um utente internado, inscrito numa USF, que foi seguidamente internado no setor hospitalar. Recorreu-se à base de dados de uma USF e de um hospital, ambos pertencentes à ARS Alentejo do ano de 2010. O objetivo central consiste em estudar a relação do volume de consultas da USF e se o tipo de admissão no hospital, sendo ela programada ou não programada, explica a variância o custo do internamento. Metodologia: Foi efetuado o cruzamento entre os dados dos utentes inscritos na USF e o total de internamento hospitalar, utilizando a sua data de nascimento e respetivo sexo. Após efetuado o cruzamento, através de um procedimento estatístico com base em SPSS, foram estipuladas pressupostos de forma a encontrar uma associação entre o custo do utente internado com as variáveis da base de dados da USF. De seguida, foi verificado se o tipo de admissão do internamento pode ou não influenciar o custo do internamento. Para efetuar tais correlações, optei por separar a amostra consoante alguns dos seus grupos mais frequentes, em que foi desagregado os internamentos referentes ao GCD 14 – Gravidez, Parto e Puerpério e dos utentes pertencentes ao escalão etários dos idosos (mais de 64 anos). Resultados: A variável da idade do utente é a que mais poderá explicar a variância do custo do internamento, apresentando sempre valores significativos para tal relação. As restantes pouco ou nada podem explicar a variância do custo do internamento. Quanto à tipologia de admissão, o facto de ser programado poderá explicar a diminuição dos dias de internamento, que concomitantemente poderá diminuir o custo do internamento, devido a forte correlação existente entre elas (r=0,666). Conclusão: A introdução da integração dos cuidados de saúde a nível primário e secundário poderá ser a solução base para a redução dos gastos desnecessários na saúde. Um maior acompanhamento do utente nos CSP poderá reduzir a frequência hospitalar, como verificamos que as variáveis da USF e o facto de a consulta ser programada podem explicar tal variância.

The role of integrated home-based care in patient adherence to antiretroviral therapy

Non-adherence is one of the primary obstacles to successful antiretroviral therapy in HIV+ patients worldwide. In Brazil, the Domiciliary Therapeutic Assistance is a multidisciplinary and integrated home-based assistance program provided for HIV+ patients confined in their homes due to physical deficiency. This study investigated ADT's ability to monitor and promote appropriate adherence to ARV therapy. Fifty-six individuals were recruited from three study groups: Group 1 - patients currently in the ADT program, Group 2 - 21 patients previously treated by the ADT program, and Group 3 - 20 patients who have always been treated using conventional ambulatory care. Using multivariable self-reporting to evaluate adherence, patients in the ADT program had significantly better adherence than patients in ambulatory care (F = 6.66, p = 0.003). This effect was independent of demographic and socioeconomic characteristics as well as medical history. Patients in the ADT program also showed a trend towards greater therapeutic success than ambulatory patients. These results suggest the incorporation of characteristics of ADT in conventional ambulatory care as a strategy to increase adherence to ARV therapy.

Intestinal helminthes and/or Toxocara infection are unrelated to anti-HBs titers in seven-year-old children vaccinated at birth with recombinant hepatitis B vaccine

The aim of this investigation was to evaluate the possible effect of nematode infection on anti-HBs antibody levels in the serum of seven-year-old schoolchildren vaccinated at birth with the recombinant hepatitis B vaccine. Anti-HBs and anti HBc antibodies were evaluated in the sera of 100 schoolchildren with at least one intestinal nematode and/or a positive serological reaction for anti-Toxocara antibodies and in 95 schoolchildren without intestinal helminthiasis or serum anti-Toxocara antibodies. Both groups were from public elementary schools located on the urban periphery of Vitória, ES, Brazil. Among these 195 children, the median anti-HBs antibody titer was 31.3IU/ml and the frequency of titers less than 10IU/ml was 33.8% (95% CI: 27.1-40.4%). There were no significant differences between the medians of anti-HBs titers or the frequency of titers less than 10IU/ml between the groups with or without helminthes (29.5 and 32.9IU/ml and 33 and 34.7%, respectively; p>0.05). Even when the children with intestinal nematodes and/or anti-Toxocara antibodies and with blood eosinophil counts over 600/mm³ were compared with children without infection from intestinal nematodes and without anti-Toxocara antibodies, with blood eosinophil counts less than 400 eosinophils/mm³, these differences were not significant. None of the children presented anti-HBc antibodies. In conclusion, infections with intestinal nematodes and/or the presence of anti-Toxocara antibodies did not interfere with the anti-HBs antibody titers in seven-year-old children vaccinated at birth with the recombinant hepatitis B vaccine.
