Biofilm is an increasing problem in the healthcare and have in urinary catheters long been associated with nosocomial urinary tract infections. The infections caused in 2002 alone 13,000 deaths in the US and annual costs have been estimated to over $400 million. These costs are however most likely underestimated. The analysis of biofilm is important to aid the work on increasing patient safety and reducing the financial implications. A literature study was conducted in order to recommend a method for quantification that was fast, accurate and versatile. Methods used for biofilm quantification are primarily based upon light absorption, light scattering and changes in impedance. A few methods utilizing these properties are spectrophotometry, flow cytometry and coulter counters. Samples of biofilm are usually collected via traditional scraping with a sterile blade or with sonication (ultrasound). Flow cytometry was considered the superior method for quantification along with sonication for sample collection. The survey therefore came to the conclusion that biofilm sample collection should be done with sonication and analysis with flow cytometry. / Biofilm är ett ökande problem inom sjukvården och har i urinkatetrar länge varit associerademed sjukvårdsrelaterade urinvägsinfektioner. Infektionerna orsakade under 200213,000 dödsfall i USA och de ekonomiska kostnaderna har uppskattats till över $400miljoner. Kostnaderna antas dock vara underskattade. Analysen av biofilm är viktig förarbetet med att förbättra patientsäkerhet och minska kostnader relaterade till biofilm.En litteraturstudie användes för att rekommendera en metod som var snabb, noggrannoch mångsidig. Mätmetoder som används för kvantifiering är i huvudsak baserade påljusabsorption, ljusspridning samt förändringar i elektrisk impedans. Några metodersom använder detta är t.ex. spektrofotometri, flödescytometri samt coulter counters.Prover av biofilm samlas ofta in via traditionell skrapning med ett sterilt knivblad ellermed hjälp av ultraljud. Flödescytometri ansågs vara den bästa metoden för kvantifieringtillsammans med ultraljud för provtagning. Utifrån undersökningen drogs slutsatsen attprovtagning bör ske med ultraljud och analys med flödescytometri.

Antibiotic resistance is a global health concern. Its increasing development is seemingly due to the irresponsible use of antibiotics and their availability. To ensure the correct treatment of patients and avoid unnecessary strain on the individual and society as a whole, it is vital to ensure access to both new and old antibiotics where there is a distinct need. Temocillin is an antibiotic used in the treatment of febrile UTIs. It is currently unavailable in Sweden, although being well-established and proven effective in other European countries. Hence, this report aims to investigate the introduction of temocillin to the Swedish or Scandinavian market in regards to the economic, technical, medical, and regulatory possibilities and barriers. The research is based on literature, internet, and database reviews and empirical data collection through interviews with people of expertise within the fields of antibiotic resistance and concerned aspects. This study emphasizes the great potential of introducing temocillin to Sweden. The evident conclusion drawn is that a production of the antibiotic is not possible in Sweden in the near future. Despite this, an identified supply chain in Europe can enable a role for Sweden as a distribution country. Through a performed break-even analysis, the calculated break-even point and profit margins indicated a low risk of financial loss for a MAH acting as the supplier of temocillin, such as the company Eumedica S.A.. Only 1 % of the Swedish market would have to be covered to break even, and regardless of the estimated volumes of usage upon introduction being either 50 % or 25 % of the total medical need, a profit is likely. In addition, temocillin holds a great medical and social value. However, the obvious obstacle observed is its out-dated documentation. The dossier is of the wrong format, which complicates the regulatory procedure. Thus, this needs to be taken into consideration for an introduction to be possible.

Introdução: a infecção do trato urinário (ITU) é uma das complicações mais frequentes na gravidez, repercute negativamente sobre os índices de morbidade e mortalidade perinatal. Objetivo: o objetivo desta pesquisa foi verificar a associação entre as práticas de higiene genital e sexual e a ocorrência de ITU na gravidez. Casuística e método: foi realizado um estudo transversal, exploratório e descritivo de base hospitalar. Os dados foram coletados com 220 (N) puérperas que receberam assistência ao parto em um hospital público localizado na Cidade de São Paulo. Um formulário estruturado foi utilizado para coletar os dados com as puérperas que foram introduzidos em um banco de dados do Epi Info e analisados no Programa estatístico Statistical Package for Social Sciences (SPSS) for Windows versão 12.0. O Teste Qui-Quadrado foi feito para verificar a existência de associação entre as variáveis independentes e a ocorrência da ITU na gravidez. Foram consideradas significativas todas as associações, cujos resultados apresentaram p<0,05. Conclusões e considerações finais: Quanto às características sociodemográficas das puérperas, a maior proporção tinha idade entre 20 a 29 anos (51,8%), estudou até o ensino médio (46,4%), era católica (48,7%), tinha filhos (60%) e parceiro fixo (91,8%). Seus parceiros apresentaram características semelhantes. Não foi identificada existência de associação significativa (p<0,05) entre as características sociodemográficas da gestante e seu parceiro, da assistência pré-natal, paridade e tipo de parto, disponibilidade de banheiro, higienização das roupas íntimas, hábito de uso de absorventes higiênicos, práticas de higiene genital das puérperas e parceiros antes e após as eliminações vesicointestinais e no coito, hábitos sexuais e a ocorrência da ITU na gravidez. A ocorrência desta patologia na gravidez foi autorreferida por 33,2% das puérperas. Chamou atenção o fato de algumas puérperas (0,9%) não realizarem higiene genital, após as eliminações intestinais. Informações sistematizadas sobre os hábitos de higiene genital devem ser obtidas para que as demandas individuais sejam identificadas e atendidas. A inexistência de associações significativas entre as variáveis estudadas nesta pesquisa e a ocorrência da ITU na gravidez indicou que outras dimensões da vida de gestante devem ser enfocadas nas futuras pesquisas / Introduction: Urinary tract infection (UTI), which is one of the most frequent complications during pregnancy, negatively affects perinatal morbidity and mortality ratios. Objective: This research aimed to verify the association between genital and sexual hygiene practice and the occurrence of UTI during pregnancy. Cases and method: A cross-sectional, exploratory and descriptive hospital-based study was carried out. Data were collected from 220 (N) puerperal women who received delivery care at a public hospital in São Paulo City, Brazil. A structured form was used for data collection. Data were fed into an Epi Info database and analyzed in Statistical Package for Social Sciences (SPSS) for Windows version 12.0. The Chi-Square Test was performed to check for associations between the independent variables and the occurrence of UTI in pregnancy. All associations with p<0.05 were considered significant. Conclusions and final considerations: As to these womens sociodemographic characteristics, a majority was between 20 and 29 years old (51.8%), finished secondary education (46.4%), was catholic (48.7%), had children (60%) and a fixed partner (91.8%). Their partners presented similar characteristics. No significant association (p<0.05) was identified between the sociodemographic characteristics of the pregnant woman and her partner, prenatal care, parity and delivery type, availability of bathroom, washing of intimate clothing, habit to use sanitary towels, genital hygiene practices of the puerperal women and their partners before and after urinary-intestinal eliminations and after coitus, sexual habits and the occurrence of UTI during pregnancy. The occurrence of this disease during pregnancy was self-referred by 33.2% of the women. It was remarkable that some women (0.9%) did not perform genital hygiene after intestinal eliminations. Systemized information on genital hygiene habits should be obtained with a view to identifying and responding to individual demands. The lack of significant associations between the research variables and the occurrence of UTI during pregnancy indicated that other dimensions of the pregnant womans life should be focused on in future research

INTRODUÇÃO: As infecções do trato urinário (ITU) feminino são muito prevalentes em mulheres. Em geral, elas dividem-se em cistites e pielonefrites de acordo com seu nível anatômico. Seu tratamento, apesar de simples, depende do conhecimento da flora bacteriana e do padrão de sensibilidade local, principalmente em tempos de aumento de resistência bacteriana. Este estudo avaliou e comparou a flora e o padrão de sensibilidade das bactérias causadoras de infecção não complicada do trato urinário feminino no período de 2007 a 2012. MÉTODOS: Analisamos retrospectivamente os resultados de 493 culturas de urina de pacientes com idade a partir de 14 anos e sintomas clínicos de cistite ou pielonefrite tratadas no Pronto-Socorro ou Ambulatório de Urologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. As pacientes foram separadas em três grupos: 1- pacientes com cistite simples atendidas no Pronto-Socorro; 2- pacientes com cistite simples atendidas no Ambulatório; 3- pacientes com pielonefrite atendidas no Pronto-Socorro. As características demográficas como idade, presença de ITU de repetição, diabetes mellitus (DM) e outras comorbidades, e os resultados de flora bacteriana e padrão de sensibilidade foram analisados e comparados entre os grupos. RESULTADOS: A média de idade das pacientes nos três grupos foi 43,2, 55,0 e 36,0 anos, respectivamente. ITU de repetição esteve presente em 36,0%, 76,1% e 26,5% das pacientes dos grupos 1, 2 e 3, respectivamente, enquanto que 8,5%, 22,7% e 2,2% das pacientes nos grupos 1, 2 e 3, respectivamente, eram diabéticas. Escherichia coli (E. coli) foi a bactéria responsável por 75,1% das infecções no geral e 87,3% das pielonefrites. Staphylococcus saprophyticus foi o segundo agente etiológico mais frequente (6,7%), principalmente no grupo 1 (10,0%), enquanto que nas diabéticas, Enterococcus faecalis foi o segundo agente etiológico (15,6%). Ao avaliarmos todas as pacientes, o antibiograma demonstrou sensibilidade à amoxacilina/ácido clavulânico (AAC), ampicilina, ciprofloxacina, levofloxacina, nitrofurantoína, norfloxacina e sulfametoxazol/trimetoprima (SMT) de 85,8%, 46,5%, 82,0%, 83,3%, 88,3%, 83,3% e 65,7%, respectivamente. Nas pielonefrites, a sensibilidade geral à cefalotina, cefepime, ceftriaxone, ciprofloxacina e gentamicina foi de 67,0%, 95,5%, 94,3%, 81,8% e 98,0%, respectivamente. Ao analisarmos apenas as infecções por E. coli, os antibióticos orais com sensibilidade > 90% foram AAC (96,5%) e nitrofurantoína (98,8%). No geral, ao compararmos pacientes sem e com ITU de repetição, os antibióticos amicacina, gentamicina e nitrofurantoína foram os únicos que não apresentaram diminuição significativa de sensibilidade. Nas infecções de repetição por E. coli, os únicos antibióticos orais que mantiveram sensibilidade > 90% foram AAC e nitrofurantoína. Ao compararmos ITU por E. coli nas pacientes = 50 anos, os antimicrobianos orais que mantiveram sensibilidade > 90% em ambas faixas etárias foram AAC e nitrofurantoína. Nas pacientes diabéticas, houve diminuição estatística da sensibilidade ao ácido nalidíxico (80,5% x 61,5%), ciprofloxacina (84,8% x 65,1%), gentamicina (97,4% x 81,0%), levofloxacina (85,4% x 66,7%) e SMT (66,0% x 50%), respectivamente. As infecções por E. coli nas pacientes diabéticas também apresentaram diminuição estatística aos mesmos antibióticos; AAC e nitrofurantoína mantiveram sensibilidade > 95% nesta situação. Análise de regressão logística identificou aumento de chance de resistência ao ácido nalidíxico, ciprofloxacina e levofloxacina de 3,62, 4,72 e 5,27, respectivamente, quando há ITU de repetição, e à gentamicina de 5,38 quando há DM. CONCLUSÕES: Pielonefrites foram mais comuns em mulheres jovens em relação às cistites. E. coli foi o principal agente causador das infecções urinárias não complicadas, principalmente em pielonefrites. A nitrofurantoína manteve sensibilidade in vitro acima de 90% em diversas situações como no tratamento geral das cistites por E. coli, em casos de cistite de repetição, em mulheres > 50 anos e em diabéticas. AAC mostrou sensibilidade in vitro acima de 90% em algumas situações: ITU de repetição por E. coli, mulheres com idade >= 50 anos e diabéticas. A ceftriaxone apresentou sensibilidade in vitro suficiente para o tratamento empírico de pielonefrite. O histórico de infecção urinária de repetição aumentou a chance de resistência ao ácido nalidíxico, ciprofloxacina e levofloxacina e DM aumentou a chance de resistência à gentamicina. / INTRODUCTION: Uncomplicated urinary tract infections (UTIs) in women are common. Urinary tract infections are usually divided into cystitis or pyelonephritis, according to anatomical level. Although treatment of UTI is simple, it depends on knowledge of the local uropathogens and antimicrobial susceptibility patterns due to increasing antimicrobial resistance. This study analyzed the causative pathogens of UTIs in women and their susceptibility patterns between 2007 and 2012. METHODS: We conducted a retrospective analysis of 493 urine culture results of female patients aged 14 years and older with clinical diagnosis of cystitis or pyelonephritis who were treated at the urological emergency unit or urological outpatient clinic. Patients were divided into three groups: 1- simple cystitis attended to in the emergency unit; 2- simple cystitis attended to in the urological outpatient clinic; 3- pyelonephritis attended to in the emergency unit. Results of demographic data, such as age, history of recurrent UTI, diabetes mellitus (DM) and comorbidities, and those of the causative pathogens and their susceptibility patterns were analyzed and compared. RESULTS: The mean age for groups 1, 2 and 3 was 43.2, 55.0 and 36.0 years, respectively. Recurrent UTI was present in 36.0%, 76.1% and 26.5% of patients in groups 1, 2 and 3, respectively. DM was present in 8.5%, 22.7% and 2.2% of patients in group 1, 2 and 3, respectively. Escherichia coli (E. coli) was responsible for 75.1% of all UTIs and 87.3% of pyelonephritis. Staphylococcus saprophyticus was the second most common agent (6.7%), mainly in group 1 (10.0%), while Enterococcus faecalis was the second most common agent in diabetic patients (15.6%). General susceptibility rates to amoxicillin/clavulanate (A/C), ampicillin, ciprofloxacin, levofloxacin, nitrofurantoin, norfloxacin and sulfamethoxazole/trimethoprim (SMT) were 85.8%, 46.5%, 82.0%, 83.3%, 88.3%, 83.3% and 65.7%, respectively. For pyelonephritis, the general susceptibility rates to cephalothin, cefepime, ceftriaxone, ciprofloxacin and gentamicin were 67.0%, 95.5%, 94.3%, 81.8% and 98.0%, respectively. Analysis of the E.coli isolates showed that more than 90% of the strains were susceptible to A/C (96.5%) and nitrofurantoin (98.8%). There was a decrease in the susceptibility rates to all antimicrobials in patients with recurrent UTI, except for amikacin, gentamicin and nitrofurantoin. In cases of recurrent UTI by E. coli, susceptibility rates for oral nitrofurantoin and A/C were above 90%. In a comparison of patients below 50 years and those aged 50 and older diagnosed with E. coli UTI, only A/C and nitrofurantoin maintained susceptibility rates above 95% for all ages. Comparison between diabetic and non-diabetic patients showed a significant decrease in susceptibility rates for ciprofloxacin (84.8% x 65.1%), gentamicin (97.4% x 81.0%), levofloxacin (85.4% x 66.7%), nalidixic acid (80.5% x 61.5%) and SMT (66.0% x 50%), respectively. A similar susceptibility rate of E. coli was found in diabetic patients; however, A/C and nitrofurantoin maintained susceptibility rates above 95% in this situation. A multivariate analysis identified an increased odds of resistance to ciprofloxacin, levofloxacin and nalidixic acid (OR=4.72, 5.27 and 3.62, respectively) in the presence of recurrent UTI, while there was an increased probability for resistance to gentamicin (OR=5.38) in the presence of DM. CONCLUSIONS: Pyelonephritis was more common in young women than cystitis. E. coli was the main agent for uncomplicated UTI, particularly for pyelonephritis. Nitrofurantoin maintained in vitro susceptibility rates above 90% in many situations, such as E. coli infections, recurrent infections, women older than 50 years and diabetic patients. A/C maintained susceptibility rates above 90 % in some situations, such as recurring UTI caused by E. coli, women aged 50 years or older and diabetic patients. Ceftriaxone had a sufficient in vitro susceptibility profile to be indicated for empirical treatment of pyelonephritis. Recurrent UTI increased the odds of resistance to ciprofloxacin, levofloxacin and nalidixic acid, while DM increased the chance of resistance to gentamicin

O progresso tecnológico na área da saúde permitiu desenvolver recursos materias como a fralda descartável com a finalidade de facilitar e melhorar as condições de trabalho dos profissionais de enfermagem bem como favorecer a qualidade da assistência e o conforto do paciente. Todavia, as evidências científicas do uso desse dispositivo não acompanharam a evolução tecnológica no mesmo ritmo o que pode ser observado pela ausência de estudos a respeito da assistência de enfermagem aos pacientes adultos hospitalizados que fazem uso de fralda descartável. O objetivo deste estudo foi analisar o impacto do uso de fraldas descartáveis no paciente adulto hospitalizado através do método de análise de sobrevivência. A amostra foi composta por 183 pacientes usuários de fralda descartável durante a hospitalização, internados através do serviço de urgência e emergência de um Hospital de Ensino referência para o atendimento de alta complexidade, na cidade de São Paulo, no período de março a maio de 2014. Os pacientes caracterizaram-se por serem do gênero masculino (62,3%), casados (30,1%), com idade média de 54,0 anos, provenientes da residência. Houve predomínio das afecções traumáticas, cardiovasculares e do aparelho digestivo. O tempo médio do uso de fralda descartável foi de 10,6 dias, sendo os trinta primeiros dias, período crítico para o desenvolvimento de infecção de trato urinário e lesões cutâneas relacionadas ao uso de fralda. Na amostra estudada as lesões cutâneas relacionadas ao uso de fralda tiveram incidência de 14,2% e as infecções do trato urinário tiveram incidência de 10,9%. A covariável gênero teve forte associação no desenvolvimento de infecção do trato urinário, com p< 0,5; as demais covariáveis para infecção do trato urinário, bem como o gênero e as covariáveis para as lesões cutâneas relacionadas ao uso de fralda foram descritas através de estatística descritiva por não apresentarem associação relevante. No Brasil, o presente trabalho destaca-se por ser pioneiro em caracterizar a população adulta usuária de fralda descartável, identificando aspectos relevantes ao cuidado de enfermagem necessários a uma assistência de qualidade, bem como pontuar o período crítico de prevenção para infecção de trato urinário e as lesões cutâneas relacionadas ao uso deste dispositivo, no qual devem ser concentradas as ações de vigilância / Technological progress in health has allowed to develop material resources such as the disposable diaper in order to facilitate and improve the working conditions of nursing professionals and also to support the quality of care and patient comfort. Nevertheless, the scientific evidences of the use of this device did not follow the technological developments in the same pace, which can be observed by the absence of studies on nursing care to adult hospitalized patients who use disposable diapers. The aim of this study was to analyze the impact of the usage of disposable diapers in the hospitalized adult patient by the method of survival analysis. The sample consisted of 183 patients, users of disposable diaper during hospitalization, admitted through the urgency and emergency services of a Teaching Hospital, reference in services of high-complexity care in the city of Sao Paulo, in the period from March to May, 2014. The patients were characterized by being male (62.3%), married (30.1%), with mean age of 54.0 years, and outpatients. There was a predominance on traumatic, cardiovascular and digestive tract conditions. The average time of disposable diaper usage was 10.6 days, the first thirty days being critical to the development of urinary tract infections and skin disorders related to the period of the diaper usage. In the studied sample, there was a 14.2% incidence of skin lesions related to diaper usage, and a 10.9% incidence of urinary tract infections. The covariate gender was strongly associated in the development of urinary tract infection, with p< 0.5; the other covariates for urinary tract infection, as well as gender and covariates for the skin lesions related to diaper usage were described using descriptive statistics since they did not present relevant association. In Brazil, this research stands out as being pioneer in characterizing adult disposable diaper user population, identifying relevant aspects to nursing care required for a quality service, and also pointing the critical period for the prevention of urinary tract infection and skin lesions related to the use of this device, to which surveillance actions should be concentrated

A incidência de infecção do trato urinário (ITU) em pacientes submetidos a radioterapia pélvica com sintomas de cistite varia entre 6% e 45%. O diagnóstico de ITU é tipicamente realizado através dos sintomas de cistite associados à leucocitúria. Não há evidências para essa abordagem em indivíduos submetidos a radioterapia na pelve, pois essa população pode apresentar sintomas de cistite secundários ao câncer ou ao seu tratamento. O objetivo deste estudo foi avaliar a incidência de ITU em pacientes com sintomas de cistite submetidos à radioterapia pélvica. Realizou-se um estudo de coorte prospectivo cujos critérios de inclusão foram pacientes maiores de 18 anos, com câncer primário pélvico, tratados com intuito curativo e bom estado de performance. Foram excluídos pacientes em tratamento para ITU, usuários de cateteres urinários, pacientes em diálise, com cistostomia ou nefrostomia e uso de antibiótico durante o tratamento. O recrutamento ocorreu antes do início da radioterapia, realizou-se exame de urina tipo I e urocultura. Após o início do tratamento, foram realizadas consultas com avaliação semanal dos sintomas urinários segundo critérios do Radiation Therapy Oncology Group (RTOG). Em caso de aparecimento de novos sintomas urinários ou piora daqueles já existentes, aplicava-se questionário e colhia-se um segundo exame de urina tipo I e urocultura. O diagnóstico de ITU foi definido por urocultura com crescimento bacteriano maior que 104 CFU/mL. Entre setembro de 2014 e novembro de 2015 foram recrutados sequencialmente 112 pacientes. Destes, 29 (26%) não realizaram o primeiro exame. Entre os que realizaram o exame, 11 (10%) apresentaram urocultura positiva e foram excluídos. Restaram 72 (64%) pacientes no estudo. No seguimento destes, 24 (33%) pacientes apresentaram sintomas urinários novos ou piora dos sintomas pré-existentes. Apenas um (1,4%) paciente apresentou confirmação de ITU na segunda urocultura. Observamos uma incidência de ITU menor que a esperada. Isso pode ser explicado pela realização de urocultura pré-tratamento e exclusão dos pacientes com o exame positivo. Além disso, foi realizada investigação urinária apenas em pacientes sintomáticos. Esse controle da população estudada sugere que os dados da literatura relacionados à frequência de ITU até então sejam, na verdade, relacionados a pacientes com bacteriúria assintomática que desenvolveram sintomas devido à radioterapia. Dessa forma, concluímos que nosso achado é clinicamente muito relevante, pois através de uma avaliação prospectiva e controlada, encontramos uma incidência de ITU bem menor que a estimada até então pela literatura / The incidence of urinary tract infection (UTI) in patients undergoing pelvic radiotherapy with symptoms of cystitis varies from 6% to 45% and the diagnosis of UTI is typically made through the symptoms of cystitis associated with leukocyturia, findings that allow the use of antibiotics. However, there are no evidences for this approach in individuals undergoing pelvic radiotherapy, since this population may present symptoms of cystitis secondary to cancer or its treatment. The objective of the present study was to evaluate the incidence of UTI in patients with symptoms of cystitis submitted to pelvic radiotherapy and to identify correlated predictive factors. This was a prospective cohort study. Inclusion criteria were patients older than 18 years, with primary pelvic cancer in treatment with curative intent and good performance status. Exclusion criteria, patients being treated for UTI, use of urinary catheter, patients in dialysis, or with cystostomy or nephrostomy, and use of antibiotics during treatment. Patients were recruited before the beginning of radiotherapy, when urinalysis and urine culture were collected. After start of treatment, weekly consultations were performed with evaluation of urinary symptoms according to the Radiation Therapy Oncology Group (RTOG) scale. In case of new urinary symptoms or worsening of those already existing, a questionnaire was applied to analyze possible risk factors for UTIs and a second urinalysis and urine culture were performed. The diagnosis of UTI was defined as urine culture with a bacterial growth greater than 104 CFU / mL. From September 2014 to November 2015, 112 patients were sequentially recruited. Of these, 29 (26%) did not perform the first exam. Among those who underwent the test, 11 (10%) presented the first urine culture positive and were excluded, remaining 72 (64%) patients for the study. In the follow-up, 24 (33%) patients presented new urinary symptoms or worsened of pre-existing symptoms. In only one (1.4%) patient UTI was confirmed in the second urine culture. The incidence of UTI was lower than expected in this population. This can be explained by the performance of the pre-treatment evaluation with urine culture with exclusion of patients with positive exam. In addition, a urinary investigation was performed only in symptomatic patients. This control of the population studied suggests that the literature data related to the frequency of UTI so far may be related to patients with asymptomatic bacteriuria who developed symptoms due to radiotherapy. Thus, we conclude that our finding is clinically very relevant, since through a prospective and controlled evaluation, an incidence of UTI much lower than that estimated so far in the literature was detected

Bakgrund: Urinvägsinfektioner är en av de vanligaste vårdrelaterade infektionerna inom svensk sjukvård. Varje år drabbas 65 000 personer av en vårdrelaterad infektion, av dessa är 14 % urinvägsrelaterad. Detta medför onödigt lidande för patienten, men ger också upphov till förlängda vårdtider och ökade kostnader för hälso- och sjukvården. Syfte: Syftet var att beskriva hur sjuksköterskan kan arbeta preventivt för att minska förekomsten av vårdrelaterade urinvägsinfektioner. Metod: Studiens design var en litteraturöversikt innehållande 15 vetenskapliga artiklar, varav 13 stycken var kvantitativa och två stycken var kvalitativa. Datainsamlingen har skett via sökningar i databaserna PubMed och Cinahl, valda artiklar granskades med granskningsmallar och sammanställdes sedan i resultatet. Resultat: Resultatet visade att ett förebyggande arbete kring rutiner vid kateterisering innebar minskade risker för att drabbas av urinvägsinfektioner. Utbildning och ökad medvetenhet kring hygien visade sig ha en positiv effekt både hos patienter och bland personal. Det påvisades även ett positivt samband med ett ökat vätskeintag samt kosttillskott i form av tranbärskapslar. Slutsats: För att minska vårdrelaterade urinvägsinfektioner krävs det att sjuksköterskan har en följsamhet i det förebyggande arbetet. Utbildning bland personal och patienter, större medvetenhet kring basala hygienrutiner och korrekt rutiner vid kateterisering har en stor betydelse i det preventiva arbetet. / Background: Urinary tract infection is one of the most common nosocomial infections in Swedish health care. Each year, 65 000 people suffer from a nosocomial infection, of which 14 % are urinary tract related. This problem causes unnecessary suffering for the patient, prolonged waiting times and increased costs for health care. Aim: The aim of this study was to describe how nurses could prevent nosocomial urinary tract infections. Methods: This was a literature review based on 15 articles. Of these, 13 studies had a quantitative approach and two studies had a qualitative approach. The data collection has been done by searching in the databases PubMed and Cinahl. Chosen articles were reviewed by using reviewing templates, analyzed and were compiled in the result. Results: The result showed that proactive work regarding routines when catheterize amounted to less risks for patients suffering from urinary tract infections. Education and increased awareness around hygiene turned out to have a positive effect on patients in decreasing urinary tract infections and on staff behavior. There was also a positive correlation between an increased fluid intake and cranberry capsules as a supplement. Conclusion: To reduce nosocomial urinary tract infections it is required that the nurse is involved in the proactive work. Education for staff and patients, greater awareness around basic hygiene routines and correct routines when catheterizing has a big impact on the proactive work.

The aim of this thesis was to explore the features of asymptomatic bacteriuria (ASB) in elderly people living in the community, and to seek diagnostic tools to discriminate between ASB and symptomatic urinary tract infection (UTI). All men and women aged 80 and over living in an urban district of Falun, Sweden, were invited to participate. Urine samples were obtained together with information on symptoms and on health indicators. The same cohort was surveyed again after 6 and 18 months. Urinary cytokines were analysed in 16 patients with UTI, in 24 subjects with ASB and in 20 negative controls. ASB occurred at baseline in 19.0% of women and 9.4% of men, and was found at least once in 36.9% of women and in 20.2% of men. ASB in women was associated with reduced mobility and urge urinary incontinence. Of those with ASB at baseline, 60% still had bacteriuria at 6 and 18 months, but among those with repeated findings of ASB with E. coli, only 40% had the same bacterial strain after 18 months. In women, the risk of developing a UTI within 24 months was higher among those with ASB at baseline than in those without. Urinary levels of cytokines (CXCL1, CXCL8 and IL-6) and leukocyte esterase were higher in patients with UTI than in patients with ASB. There is convincing evidence that ASB is harmless and should not be treated with antibiotics. However, such treatment is still often given, thereby unnecessarily contributing to the increased number of bacteria resistant to common antibiotics. This study confirms the high prevalence of ASB in elderly people living in the community. In order not to be misled by a urinary test showing bacteria, it is important to restrict urinary testing for bacteria to patients where there is a suspicion of UTI. In elderly patients with diffuse symptoms or in patients who are unable to communicate their symptoms, further diagnostic help could possibly be obtained by evaluating the urinary levels of leukocyte esterase and/or IL-6.

Escherichia coli et Enterococcus faecalis sont deux principaux agents pathogènes impliqués dans les infections du tractus urinaire (ITU) en médecine de ville et à l’hôpital. Ces espèces bactériennes sont responsables d’ITU aigües avec des phénomènes de récurrence et dans des ITU chroniques. La consommation d'antibiotiques est directement corrélée à la résistance des bactéries uropathogènes ce qui montre l'importance de contrôler l'utilisation des antibiotiques et de développer des traitements préventifs et curatifs alternatifs pour les infections urinaires.La consommation alimentaire de cranberry et de leurs extraits est traditionnellement associée avec le maintien en bonne santé des voies urinaires. Par ailleurs, certaines études cliniques semblent montrer un effet préventif des ITU associé à la consommation alimentaire de cranberry. In vitro et ex vivo, la consommation de ces extraits par l’homme réduit l’adhérence de certaines souches d’E. coli aux cellules épithéliales urinaires et la formation de biofilm de différentes espèces. L’hypothèse de travail est que la consommation alimentaire d’extraits de cranberry conduise à la formation de métabolites urinaires qui diminuent l'adhérence des bactéries uropathogènes à l’épithélium urinaire. Ce mécanisme serait à la base de la prévention des ITU par consommation d’extraits de cranberry. Cependant, les métabolites bioactifs restent largement méconnus. / Escherichia coli and Enterococcus faecalis are two main pathogens involved in urinary tract infections (ITU) in town medicine and in the hospital. These bacterial species are responsible for acute UTIs with recurrence phenomena and in chronic ITUs. The consumption of antibiotics is directly correlated with the resistance of uropathogenic bacteria, which shows the importance of controlling the use of antibiotics and of developing alternative preventive and curative treatments for urinary infections.Cranberry consumption of their extracts is traditionally associated with the maintenance of healthy urinary tract. In addition, some clinical studies seem to show a preventive effect of ITUs associated with cranberry consumption. In vitro and ex vivo, the consumption of these extracts by humans reduces the adhesion of certain E. coli strains to urinary epithelial cells and biofilm formation of different species. The working hypothesis is that the consumption of cranberry extracts leads to the formation of urinary metabolites that decrease the adhesion of uropathogenic bacteria to the urinary epithelium. This mechanism would be the basis for the prevention of ITU by consumption of cranberry extracts. However, bioactive metabolites remain largely unknown.
