Preventing infections following caesarean section

Surgical site infections following caesarean section are a serious and costly adverse event for Australian hospitals. In the United Kingdom, 9% of women are diagnosed with a surgical site infection following caesarean section either in hospital or post-discharge (Wloch et al 2012, Ward et al 2008). Additional staff time, pharmaceuticals and health supplies, and increased length of stay or readmission to hospital are often required (Henman et al 2012). Part of my PhD investigated the economics of preventing post-caesarean infection. This paper summarises a review of relevant infection prevention strategies. Administering antibiotic prophylaxis 15 to 60 minutes pre-incision, rather than post cordclamping, is probably the most important infection prevention strategy for caesarean section (Smaill and Gyte2010, Liu et al 2013, Dahlke et al 2013). However the timing of antibiotic administration is reportedly inconsistent in Australian hospitals. Clinicians may be taking advice from the influential, but out-dated RANZCOG and United States Centers for Disease Control and Prevention guidelines (Royal Australian and New Zealand College of Obstetricians and Gynaecologists 2011, Mangram et al 1999). A number of other important international clinical guidelines, including Australia's NHMRC guidelines, recommend universal prophylactic antibiotics pre-incision for caesarean section (National Health and Medical Research Council 2010, National Collaborating Centre for Women's and Children's Health 2008, Anderson et al 2008, National Collaborating Centre for Women's and Children's Health 2011, Bratzler et al 2013, American College of Obstetricians and Gynecologists 2011a, Antibiotic Expert Group 2010). We need to ensure women receive preincision antibiotic prophylaxis, particularly as nurses and midwives play a significant role in managing an infection that may result from sub-optimal practice. It is acknowledged more explicitly now that nurses and midwives can influence prescribing and administration of antibiotics through informal approaches (Edwards et al 2011). Methods such as surgical safety checklists are a more formal way for nurses and midwives to ensure that antibiotics are administered pre-incision (American College of Obstetricians and Gynecologists 2011 b). Nurses and midwives can also be directly responsible for other infection prevention strategies such as instructing women to not remove pubic hair in the month before the expected date of delivery and wound management education (Ng et al 2013). Potentially more costly but effective strategies include using a Chlorhexidine-gluconate (CHG) sponge preoperatively (in addition to the usual operating room skin preparation) and vaginal cleansing with a povidone-iodine solution (Riley et al 2012, Rauk 2010, Haas, Morgan, and Contreras 2013).

The relationship between emotional intelligence and depression in a clinical sample

Background and Objectives: Although depression is a commonly occurring mental illness, research concerning strategies for early detection and prophylaxis has not until now focused on the possible utility of measures of Emotional Intelligence (EI) as a potential predictive factor. The current study aimed to investigate the relationship between EI and a clinical diagnosis of depression in a cohort of adults. Methods: Sixty-two patients (59.70% female) with a DSM-IV-TR diagnosis of a major affective disorder and 39 aged matched controls (56.40% female) completed self-report instruments assessing EI and depression in a cross-sectional study. Results: Significant associations were observed between severity of depression and the EI dimensions of Emotional Management (r = -0.56) and Emotional Control (r = -0.62). The results show a reduced social involvement, an increased prior institutionalization and an increased incidence of "Schizophrenic Psychosis" and "Abnormal Personalities" in the sub-group of repeated admissions. Conclusions: Measures of EI may have predictive value in terms of early identification of those at risk for developing depression. The current study points to the potential value of conducting further studies of a prospective nature.

Clinical factors associated with the humoral immune response to influenza vaccination in chronic obstructive pulmonary disease

Background and objective Individuals with chronic obstructive pulmonary disease (COPD) are at a high risk of developing significant complications from infection with the influenza virus. It is therefore vital to ensure that prophylaxis with the influenza vaccine is effective in COPD. The aim of this study was to assess the immunogenicity of the 2010 trivalent influenza vaccine in persons with COPD compared to healthy subjects without lung disease, and to examine clinical factors associated with the serological response to the vaccine. Methods In this observational study, 34 subjects (20 COPD, 14 healthy) received the 2010 influenza vaccine. Antibody titers at baseline and 28 days post-vaccination were measured using the hemagglutination inhibition assay (HAI) assay. Primary endpoints included seroconversion (≥4-fold increase in antibody titers from baseline) and the fold increase in antibody titer after vaccination. Results Persons with COPD mounted a significantly lower humoral immune response to the influenza vaccine compared to healthy participants. Seroconversion occurred in 90% of healthy participants, but only in 43% of COPD patients (P=0.036). Increasing age and previous influenza vaccination were associated with lower antibody responses. Antibody titers did not vary significantly with cigarette smoking, presence of other comorbid diseases, or COPD severity. Conclusion The humoral immune response to the 2010 influenza vaccine was lower in persons with COPD compared to non-COPD controls. The antibody response also declined with increasing age and in those with a history of prior vaccination.

Potential Human Exposure to Australian Bat Lyssavirus, Queensland, 1996-1999

Two human deaths caused by Australian bat lyssavirus (ABL) infection have been reported since 1996. Information was obtained from 205 persons (mostly adults from south Brisbane and the South Coast of Queensland), who reported potential ABL exposure to the Brisbane Southside Public Health Unit from November 1,1996, to January 31, 1999. Volunteer animal handlers accounted for 39% of potential exposures, their family members for 12%, professional animal handlers for 14%, community members who intentionally handled bats for 31%, and community members with contacts initiated by bats for 4%. The prevalence of Lyssavirus detected by fluorescent antibody test in 366 sick, injured, or orphaned bats from the area was 6%. Sequelae of exposure, including the requirement for expensive postexposure prophylaxis, may be reduced by educating bat handlers and the public of the risks involved in handling Australian bats.

Mediastinitis after cardiac surgery

Mediastinitis as a complication after cardiac surgery is rare but disastrous increasing the hospital stay, hospital costs, morbidity and mortality. It occurs in 1-3 % of patients after median sternotomy. The purpose of this study was to find out the risk factors and also to investigate new ways to prevent mediastinitis. First, we assessed operating room air contamination monitoring by comparing the bacteriological technique with continuous particle counting in low level contamination achieved by ultra clean garment options in 66 coronary artery bypass grafting operations. Second, we examined surgical glove perforations and the changes in bacterial flora of surgeons' fingertips in 116 open-heart operations. Third, the effect of gentamicin-collagen sponge on preventing surgical site infections (SSI) was studied in randomized controlled study with 557 participants. Finally, incidence, outcome, and risk factors of mediastinitis were studied in over 10,000 patients. With the alternative garment and textile system (cotton group and clean air suit group), the air counts fell from 25 to 7 colony-forming units/m3 (P<0.01). The contamination of the sternal wound was reduced by 46% and that of the leg wound by >90%. In only 17% operations both gloves were found unpunctured. Frequency of glove perforations and bacteria counts of hands were found to increase with operation time. With local gentamicin prophylaxis slightly less SSIs (4.0 vs. 5.9%) and mediastinitis (1.1 vs. 1.9%) occurred. We identified 120/10713 cases of postoperative mediastinitis (1.1%). During the study period, the patient population grew significantly older, the proportion of women and patients with ASA score >3 increased significantly. In multivariate logistic regression analysis, the only significant predictor for mediastinitis was obesity. Continuous particle monitoring is a good intraoperative method to control the air contamination related to the theatre staff behavior during individual operation. When a glove puncture is detected, both gloves are to be changed. Before donning a new pair of gloves, the renewed disinfection of hands will help to keep their bacterial counts lower even towards the end of long operation. Gentamicin-collagen sponge may have beneficial effects on the prevention of SSI, but further research is needed. Mediastinitis is not diminishing. Larger populations at risk, for example proportions of overweight patients, reinforce the importance of surveillance and pose a challenge in focusing preventive measures.

Surveillance of Surgical Site Infections following Major Hip and Knee Surgery in Finland

Background and aims. Since 1999, hospitals in the Finnish Hospital Infection Program (SIRO) have reported data on surgical site infections (SSI) following major hip and knee surgery. The purpose of this study was to obtain detailed information to support prevention efforts by analyzing SIRO data on SSIs, to evaluate possible factors affecting the surveillance results, and to assess the disease burden of postoperative prosthetic joint infections in Finland. Methods. Procedures under surveillance included total hip (THA) and total knee arthroplasties (TKA), and the open reduction and internal fixation (ORIF) of femur fractures. Hospitals prospectively collected data using common definitions and written protocol, and also performed postdischarge surveillance. In the validation study, a blinded retrospective chart review was performed and infection control nurses were interviewed. Patient charts of deep incisional and organ/space SSIs were reviewed, and data from three sources (SIRO, the Finnish Arthroplasty Register, and the Finnish Patient Insurance Centre) were linked for capture-recapture analyses. Results. During 1999-2002, the overall SSI rate was 3.3% after 11,812 orthopedic procedures (median length of stay, eight days). Of all SSIs, 56% were detected after discharge. The majority of deep incisional and organ/space SSIs (65/108, 60%) were detected on readmission. Positive and negative predictive values, sensitivity, and specificity for SIRO surveillance were 94% (95% CI, 89-99%), 99% (99-100%), 75% (56-93%), and 100% (97-100%), respectively. Of the 9,831 total joint replacements performed during 2001-2004, 7.2% (THA 5.2% and TKA 9.9%) of the implants were inserted in a simultaneous bilateral operation. Patients who underwent bilateral operations were younger, healthier, and more often males than those who underwent unilateral procedures. The rates of deep SSIs or mortality did not differ between bi- and uni-lateral THAs or TKAs. Four deep SSIs were reported following bilateral operations (antimicrobial prophylaxis administered 48-218 minutes before incision). In the three registers, altogether 129 prosthetic joint infections were identified after 13,482 THA and TKA during 1999-2004. After correction with the positive predictive value of SIRO (91%), a log-linear model provided an estimated overall prosthetic joint infection rate of 1.6% after THA and 1.3% after TKA. The sensitivity of the SIRO surveillance ranged from 36% to 57%. According to the estimation, nearly 200 prosthetic joint infections could occur in Finland each year (the average from 1999 to 2004) after THA and TKA. Conclusions. Postdischarge surveillance had a major impact on SSI rates after major hip and knee surgery. A minority of deep incisional and organ/space SSIs would be missed, however, if postdischarge surveillance by questionnaire was not performed. According to the validation study, most SSIs reported to SIRO were true infections. Some SSIs were missed, revealing some weakness in case finding. Variation in diagnostic practices may also affect SSI rates. No differences were found in deep SSI rates or mortality between bi- and unilateral THA and TKA. However, patient materials between these two groups differed. Bilateral operations require specific attention paid to their antimicrobial prophylaxis as well as to data management in the surveillance database. The true disease burden of prosthetic joint infections may be heavier than the rates from national nosocomial surveillance systems usually suggest.

Infections in lung and heart transplant recipients : Studies on the impact of bronchoscopy in the diagnosis of respiratory infections and detection of viral infections in blood and bronchoalveolar lavage fluid

Infection is a major cause of mortality and morbidity after thoracic organ transplantation. The aim of the present study was to evaluate the infectious complications after lung and heart transplantation, with a special emphasis on the usefulness of bronchoscopy and the demonstration of cytomegalovirus (CMV), human herpes virus (HHV)-6, and HHV-7. We reviewed all the consecutive bronchoscopies performed on heart transplant recipients (HTRs) from May 1988 to December 2001 (n = 44) and lung transplant recipients (LTRs) from February 1994 to November 2002 (n = 472). To compare different assays in the detection of CMV, a total of 21 thoracic organ transplant recipients were prospectively monitored by CMV pp65-antigenemia, DNAemia (PCR), and mRNAemia (NASBA) tests. The antigenemia test was the reference assay for therapeutic intervention. In addition to CMV antigenemia, 22 LTRs were monitored for HHV-6 and HHV-7 antigenemia. The diagnostic yield of the clinically indicated bronchoscopies was 41 % in the HTRs and 61 % in the LTRs. The utility of the bronchoscopy was highest from one to six months after transplantation. In contrast, the findings from the surveillance bronchoscopies performed on LTRs led to a change in the previous treatment in only 6 % of the cases. Pneumocystis carinii and CMV were the most commonly detected pathogens. Furthermore, 15 (65 %) of the P. carinii infections in the LTRs were detected during chemoprophylaxis. None of the complications of the bronchoscopies were fatal. Antigenemia, DNAemia, and mRNAemia were present in 98 %, 72 %, and 43 % of the CMV infections, respectively. The optimal DNAemia cut-off levels (sensitivity/specificity) were 400 (75.9/92.7 %), 850 (91.3/91.3 %), and 1250 (100/91.5 %) copies/ml for the antigenemia of 2, 5, and 10 pp65-positive leukocytes/50 000 leukocytes, respectively. The sensitivities of the NASBA were 25.9, 43.5, and 56.3 % in detecting the same cut-off levels. CMV DNAemia was detected in 93 % and mRNAemia in 61 % of the CMV antigenemias requiring antiviral therapy. HHV-6, HHV-7, and CMV antigenemia was detected in 20 (91 %), 11 (50 %), and 12 (55 %) of the 22 LTRs (median 16, 31, and 165 days), respectively. HHV-6 appeared in 15 (79 %), HHV-7 in seven (37 %), and CMV in one (7 %) of these patients during ganciclovir or valganciclovir prophylaxis. One case of pneumonitis and another of encephalitis were associated with HHV-6. In conclusion, bronchoscopy is a safe and useful diagnostic tool in LTRs and HTRs with a suspected respiratory infection, but the role of surveillance bronchoscopy in LTRs remains controversial. The PCR assay acts comparably with the antigenemia test in guiding the pre-emptive therapy against CMV when threshold levels of over 5 pp65-antigen positive leukocytes are used. In contrast, the low sensitivity of NASBA limits its usefulness. HHV-6 and HHV-7 activation is common after lung transplantation despite ganciclovir or valganciclovir prophylaxis, but clinical manifestations are infrequently linked to them.

Bacteriophage therapy for Staphylococcus aureus bacteremia in streptozotocin-induced diabetic mice

The protective effect of bacteriophage was assessed against experimental Staphylococcus aureus lethal bacteremia in streptozotocin (STZ) induced-diabetic and non-diabetic mice. Intraperitoneal administrations of S. aureus (RCS21) of 2 x 10(8) CFU caused lethal bacteremia in both diabetic and non-diabetic mice. A single administration of a newly isolated lytic phage strain (GRCS) significantly protected diabetic and nondiabetic mice from lethal bacteremia (survival rate 90% and 100% for diabetic and non-diabetic bacteremic groups versus 0% for saline-treated groups). Comparison of phage therapy to oxacillin treatment showed a significant decrease in RCS21 of 5 and 3 log units in diabetic and nondiabetic bacteremic mice, respectively. The same protection efficiency of phage GRCS was attained even when the treatment was delayed up to 4 h in both diabetic and non-diabetic bacteremic mice. Inoculation of mice with a high dose (10(10) PFU) of phage GRCS alone produced no adverse effects attributable to the phage per se. These results suggest that phages could constitute valuable prophylaxis against S. aureus infections, especially in immunocompromised patients. (C) 2010 Institut Pasteur.

A regulação política da sexualidade no âmbito da família por saberes e instituições médicas brasileiras : 1838-1940

Esta tese tem como objeto a regulação política da sexualidade no âmbito da família por saberes e instituições médicas brasileiras (1838-1940). Orienta-se pelo interesse em analisar continuidades e descontinuidades na construção de objetos, estratégias e táticas políticas direcionados para a regulação higiênica e eugênica do casamento e da sexualidade infantil. De inspiração foucaultiana, inscreve-se no campo da história dos saberes e está subsidiada por um conjunto heterogêneo de documentos (teses, artigos de periódicos, livros, anais etc.) circunscritos, majoritariamente, ao campo da medicina. Analisa a constituição de uma defesa higiênica dos casamentos no pensamento médico novecentista, voltada para remanejamentos das figuras de esposa e marido na nova configuração de família que começava a se esboçar no Brasil, contrastando-a com a regulação católica da moral sexual colonial. Em seguida, descreve a visibilidade higiênica que a medicina dará a infância no século XIX, problematizando especificamente o interesse pelo tema da masturbação, que articula simultaneamente a família, centrada na figura da mãe, e a escola na convocação de zelar pela criança. Partindo das contradições sociais que se apresentaram na construção do projeto liberal nacional a partir da década de 1870, discute a apropriação do discurso da degenerescência pelo saber médico-psiquiátrico brasileiro, que propiciou uma leitura da brasilidade marcada pelo excesso sexual e pela condição degenerada da miscigenação, a fim de pensar as condições de possibilidade para a emergência do projeto de eugenia matrimonial institucionalizado nas primeiras décadas do século XX e toma como táticas a campanha pela compulsoriedade do exame pré-nupcial, o combate aos casamentos consanguíneos, o controle do contágio venéreo e o aconselhamento sexual dos casais. Analisa a campanha de educação sexual, cuja pretensão de instituir uma sciencia sexual no Brasil, de legitimidade controversa, tinha como horizonte viabilizar uma profilaxia sexual que mitigasse a produção da criminalidade, das perversões sexuais e das doenças nervosas, bem como os desajustes familiares, a partir da fabricação de um novo objeto, qual seja, a sexualidade infantil, no qual incidirá uma nova pedagogia. Nesse particular, aponta particularidades discursivas da difusão das idéias freudianas entre higienistas brasileiros. Finalmente, sinaliza a constituição da higiene mental da criança como um novo domínio para a psiquiatria brasileira, que tomou a intensa circulação afetiva intrafamiliar como ponto de ancoragem para um projeto de normalização social, ainda centrado na eugenia, mas já atravessado por uma psicologia da adaptação.

Social, economic, and health impact of the respiratory syncytial virus: a systematic search

Background: Bronchiolitis caused by the respiratory syncytial virus (RSV) and its related complications are common in infants born prematurely, with severe congenital heart disease, or bronchopulmonary dysplasia, as well as in immunosuppressed infants. There is a rich literature on the different aspects of RSV infection with a focus, for the most part, on specific risk populations. However, there is a need for a systematic global analysis of the impact of RSV infection in terms of use of resources and health impact on both children and adults. With this aim, we performed a systematic search of scientific evidence on the social, economic, and health impact of RSV infection. Methods: A systematic search of the following databases was performed: MEDLINE, EMBASE, Spanish Medical Index, MEDES-MEDicina in Spanish, Cochrane Plus Library, and Google without time limits. We selected 421 abstracts based on the 6,598 articles identified. From these abstracts, 4 RSV experts selected the most relevant articles. They selected 65 articles. After reading the full articles, 23 of their references were also selected. Finally, one more article found through a literature information alert system was included. Results: The information collected was summarized and organized into the following topics: 1. Impact on health (infections and respiratory complications, mid-to long-term lung function decline, recurrent wheezing, asthma, other complications such as otitis and rhino-conjunctivitis, and mortality; 2. Impact on resources (visits to primary care and specialists offices, emergency room visits, hospital admissions, ICU admissions, diagnostic tests, and treatments); 3. Impact on costs (direct and indirect costs); 4. Impact on quality of life; and 5. Strategies to reduce the impact (interventions on social and hygienic factors and prophylactic treatments). Conclusions: We concluded that 1. The health impact of RSV infection is relevant and goes beyond the acute episode phase; 2. The health impact of RSV infection on children is much better documented than the impact on adults; 3. Further research is needed on mid-and long-term impact of RSV infection on the adult population, especially those at high-risk; 4. There is a need for interventions aimed at reducing the impact of RSV infection by targeting health education, information, and prophylaxis in high-risk populations.

Mapeamento de proteínas alvo para novos antifúngicos na fração microssomal e citosólica do patógeno humano Aspergillus fumigatus

A incidência de infecções fúngicas invasivas vem aumentando nos últimos anos. Estas infecções, em geral, apresentam altas taxas de mortalidade. A profilaxia com antifúngicos ainda é a estratégia mais comum na contenção da mortalidade e prevenção contra infecções fúngicas invasivas, porém, apresenta baixa eficiência, e relatos de resistência às drogas. Além disso, a terapia antifúngica é limitada a um pequeno grupo de drogas, como os polienos, azóis e equinocandinas. Desta forma, a busca de novos alvos de drogas é fundamental para o desenvolvimento de novos antifúngicos. Estudos in silico indicaram quatro genes como potenciais alvo de drogas em fungos patogênicos. Neste contexto, o objetivo deste trabalho foi verificar a expressão das proteínas codificadas por dois destes possíveis genes alvo, a proteína erg6, na fração microssomal, e trr1, na fração citosólica, em hifas de A. fumigatus. Visando alcançar este objetivo, foram primeiramente padronizadas todas as etapas de fracionamento celular visando isolar estas duas subfrações celulares de A. fumigatus. Posteriormente, foi otimizado o protocolo de extração e reidratação de proteínas microssomais bem como reidratação de proteínas citosólicas. Estes extratos foram submetidos a diferentes protocolos de fracionamento proteico em um sistema de eletroforese OFFGEL (OGE). Os resultados de Western immunoblot mostraram que estas duas proteínas, erg6 e trr1, são de fato expressas na fase filamentosa de A. fumigatus. O extrato proteico da fração microssomal submetido ao OGE em doze subfrações apresentou três subunidades da proteína erg6, reconhecidas pelo anticorpo monoclonal, com massas moleculares e pI distintos: uma subunidade de aproximadamente 79 kDa com pI entre 5,91 e 6,49, e outras duas subunidades de aproximadamente 35 kDa e 32 kDa, ambas com pI entre 6,49 e 7,08. A enzima erg6 foi descrita como um homotetrâmero em outros fungos. Porém, nossos resultados sugerem que, em A. fumigatus, a erg6 possui uma estrutura heterotetramérica. Quanto à proteína trr1, tanto no extrato total quanto nas frações resultantes do fracionamento em OGE, uma banda única de aproximadamente 40 kDa, com pI na faixa de 4,79 e 5,33, foi reconhecida pelo anticorpo policlonal. Desta forma, esta proteína parece ter uma estrutura homodimérica, assim como descrito em outros micro-organismos.

Prevenção de riscos de tromboembolismo venoso: estratégias para redução da morbimortalidade

Estudo prospectivo com abordagem quantitativa envolvendo 3 grupos distintos de sujeitos. Grupo 1 constituído por 56 pacientes avaliados para o risco de tromboembolismo venoso (TEV) em um acompanhamento de 30 meses para verificar os desfechos morte, reinternação e profilaxia de TEV. Grupo 2 constituído por 50 enfermeiros assistenciais que responderam questionários sobre TEV, com o propósito de avaliar seus conhecimentos sobre os riscos e profilaxia dessa doença em pacientes clínicos internados. Grupo 3 constituído por 100 enfermeiros assistenciais que responderam questionários similares aos respondidos pelo grupo 2, antes e após treinamento sobre profilaxia de TEV. O objetivo geral foi verificar o grau de conhecimento de enfermeiros sobre tromboembolismo venoso considerando sua inserção no processo de prevenção de riscos; Os objetivos específicos foram: propor e implantar uma estratégia de treinamento para capacitação de enfermeiros no rastreamento de riscos de TEV em pacientes internados; verificar o impacto do treinamento sobre TEV no conhecimento dos enfermeiros para identificação de fatores de risco dessa doença; descrever os desfechos relacionados à TEV em pacientes internados por mais de 24 horas em um hospital quaternário num seguimento de 30 meses. No grupo 1 identificou-se que o evento TEV apresenta alta mortalidade 63,6% para pacientes que não receberam profilaxia. Identificou-se também que a maioria 89,2% desses sujeitos é acompanhada de seus médicos, 53,6% passaram por reinternações e 28,6% continuam usando alguma profilaxia para TEV. No grupo 2 verificou-se que os profissionais não sabem identificar corretamente os fatores de risco para TEV, havendo grande déficit de conhecimento em relação aos fatores de risco e profilaxia da doença, pois 90% da amostra não consegue apontar mais que 5 fatores de risco para TEV considerando-se 24 fatores contemplados por consensos internacionais, demonstrando um grau de conhecimento insuficiente pela utilização de uma escala intervalar proposta nesse estudo. No grupo 3, assim como identificado no grupo 2, houve similaridade no déficit de conhecimento, pois 100% não conseguiram apontar mais que 4 fatores de risco para a doença. Identificou-se que a realização de um treinamento sobre profilaxia de TEV para esses enfermeiros apresenta alto impacto em relação ao grau de retenção de informações sobre TEV, sendo uma ação facilmente replicável para profissionais de instituições hospitalares. Concluiu-se que o uso de um algoritmo/protocolo de avaliação voltado para rastreamento de riscos de TEV por enfermeiros representa uma ferramenta importante no processo de rastreamento e prevenção dessa doença em pacientes clínicos, como proposto nesse estudo, pois nos resultados demonstrou-se que 97% dos enfermeiros do grupo 3 não conhecem qualquer tipo de protocolo relacionado a prevenção de riscos de TEV. Os sujeitos apresentaram excelente nível de conhecimento sobre meios de profilaxia mecânica, mas identificou-se que a maioria 63% nunca deu orientações sobre a profilaxia enquanto cuidam, reforçando o entendimento de que não estão inseridos no processo de prevenção de riscos de TEV para pacientes internados. A inserção dos enfermeiros nesse processo de identificação de riscos deve ser capaz de reduzir a alta taxa de morbimortalidade e reduzir a incidência dessa doença em unidades hospitalares.

Long-Term Burden and Respiratory Effects of Respiratory Syncytial Virus Hospitalization in Preterm Infants — The SPRING Study

The health status of premature infants born 32(1)-35(0) weeks' gestational age (wGA) hospitalized for RSV infection in the first year of life (cases; n = 125) was compared to that of premature infants not hospitalized for RSV (controls; n = 362) through 6 years. The primary endpoints were the percentage of children with wheezing between 2-6 years and lung function at 6 years of age. Secondary endpoints included quality of life, healthcare resource use, and allergic sensitization. A significantly higher proportion of cases than controls experienced recurrent wheezing through 6 years of age (46.7% vs. 27.4%; p = 0.001). The vast majority of lung function tests appeared normal at 6 years of age in both cohorts. In children with pulmonary function in the lower limit of normality (FEV1 Z-score [-2; -1]), wheezing was increased, particularly for cases vs. controls (72.7% vs. 18.9%, p = 0.002). Multivariate analysis revealed the most important factor for wheezing was RSV hospitalization. Quality of life on the respiratory subscale of the TAPQOL was significantly lower (p = 0.001) and healthcare resource utilization was significantly higher (p<0.001) in cases than controls. This study confirms RSV disease is associated with wheezing in 32-35 wGA infants through 6 years of age.

A nova Jericó maldita: um estudo sobre a Colônia de Iguá em Itaboraí/RJ (1935-1953)

O objetivo da pesquisa que resultou nesta dissertação consiste na análise sobre as origens do primeiro leprosário fluminense, a Colônia de Iguá, em Itaboraí, Estado do Rio de Janeiro. Busco privilegiar não só a análise desta "cidade em miniatura" tal como se pretendeu constituir um leprosário e sua estrutura mas também os impactos político-sociais ocorridos com sua fixação em um município que alimentou, durante a primeira metade do século XX, a ideia de que poderia recuperar a situação de pujança econômica e política que viveu entre os séculos XVIII e XIX, quando ocupou importante papel na economia fluminense e brasileira. Nesta análise focalizamos o movimento de resistência contra a instalação da Colônia neste município originada por aqueles que acreditavam que o leprosário iria prejudicar o reflorescimento da região, bem como as disputas políticas envolvidas em sua fixação na cidade. Também consideramos os relatos de ex-internos do antigo leprosário sobre a experiência do viver em uma colônia de atingidos pela lepra. Algumas de suas memórias foram incorporadas ao trabalho em nossa tentativa de relatar o cotidiano de um sistema que os segregou pela força do ato de internar compulsoriamente. Os marcos cronológicos da pesquisa se referem, respectivamente, ao ano de 1935, quando foi lançada a pedra fundamental para construção da Colônia de Iguá e que é também um período marcado pelo início do Plano Nacional de Combate à Lepra. Tal Plano representou uma aceleração na construção e modernização de instituições dessa natureza em todo país e marcou um momento de consolidação do internamento como profilaxia dos doentes. Como marco final, estabelecemos o ano de 1953 quando a Colônia Tavares de Macedo, como o Iguá ficou denominado a partir de 1942 recebe o novo sistema de abastecimento de água, evidenciando a aliança entre a instituição e o poder local na luta por melhorias do sistema de serviços públicos do município e, portanto, evidenciando a falsa questão de que a presença da Colônia iria prejudicar o município.
