No se halló relación entre los factores de riesgo maternos y la presencia o gravedad de la hemorragia. En cuanto a los niños, la edad gestacional menor de 31 semanas, el uso de ventilación mecánica y la persistencia del ductus arterioso mostraron una relación estadística con el evento (p < 0.05, mientras que la sumatoria de tres o más riesgos la tuvo con la gravedad del mismo (p < 0.05. Se concluye que los mencionados factores de riesgo pueden ser indicativos del desarrollo de la hemorragia de la matriz germinal en el prematuro. To facilitate clinical diagnosis of germinal matrix hemorrhage In preterm infants, a study of cases {n: 56 and controls {n: 66 was carried out. Association was investigated between hemorrhage and maternal and neonatal risk factors; also included was the correlation between such factors and seriousness of the hemorrhagic episode. No correlation was found between maternal risk factors and hemorrhage or its seriousness. Concerning neonatal risks, gestational age under 31 weeks, the use of mechanical ventilation and persistence of ductus arteriosus, independently, showed statistical correlation with the hemorrhage {p < 0.05, whereas the simultaneous presence of three or more risks correlated with intensity of hemorrhage {p < 0.05. We conclude that the abovementioned neonatal risk factors can be suggestive of the development of germinal matrix hemorrhage in preterm Infants.

Participantes: ocho madres de recién nacidos prematuros que asistieron a control al Programa Madre Canguro Integral, Hospital Universitario San Ignacio, entre noviembre de 2007 y mayo de 2008. Resultados: surgen dos temas: cuidados directos al recién nacido prematuro y el camino hacia la adaptación. El cuidado directo al recién nacido prematuro en el hogar significa para la madre cangurear, masajear, proteger del frío, alimentar al niño, mantener la higiene, conservar la protección del medio, dar amor, suministrar oxígeno suplementario al bebé si lo requiere y saber sobre las señales del niño. El camino hacia la adaptación materna tiene para las madres un objetivo: "criar el niño". Ellas manifiestan lo difícil que son las noches, expresan sus sentimientos y finalmente describen la adaptación materna como el acostumbrarse. Conclusión: la visión de las madres cuidando el recién nacido prematuro es universal: significa "cuidar mucho al niño" y estar pendientes; por otra parte, la connotación de cuidado es diversa porque cada madre lo cataloga, desde su propia percepción, como cuidado extremo, básico, esencial y especial.

Objetivo: Describir los resultados de un metaestudio sobre la adquisición del rol materno de la madre con un recién nacido prematuro hospitalizado. Materiales y Métodos: El metaestudio, involucra 3 fases analíticas: análisis metadatos, meta-método, meta-teoría, consideradas a la luz del contexto histórico, sociocultural y disciplinar. La búsqueda se realizó en: CINAHL, Medline, PsycINFO, Dissertation Abstracts. Resultados: Se incluyeron 26 investigaciones de 13 países publicadas en inglés, portugués y español (durante los años 2001-2013. Las expresiones categóricas que emergen de estas investigaciones, son: pérdida de autocontrol; experimentando dolor; buscando significado a los eventos; adaptándose a la situación; adquiriendo el rol materno y descubriendo el amor incondicional. Discusión: El metaestudio permitió el análisis crítico de la información, orientando la investigación dentro de un contexto de patrones sistemáticos, con la construcción de una alternativa de cambio del enfoque tradicional de pérdida y sufrimiento al del redescubrimiento desde la visión positiva y transformativa. Conclusiones: Reconocer la carga emocional de las madres de recién nacido prematuro obliga al equipo de salud a intervenir e idear estrategias de apoyo, para hacer menos doloroso el proceso de hospitalización de sus hijos.  Por ello el cuidado humanizado en la unidad neonatal, debe centrar sus acciones en un cuidado individual, singular, en la integralidad y respeto por la vida.Palabras clave: Maternidad, Recién Nacido Prematuro, Enfermería Neonatal. (Fuente: DeCs BIREME.Cómo citar este artículo: Villamizar B, Vargas C, Rueda E.

Full Text Available Ser madre es el resultado de un proceso que implica desarrollar una fuerte identidad maternal, este inicia en la gestación y abarca incluso los primeros meses de vida del hijo. Este proceso se nutre de la constante interacción madre-hijo. Para conocer las vivencias de las madres de niños prematuros que han requerido hospitalización, al asumir el cuidado de ellos en casa, se realizó un estudio fenomenológico con participación de diez madres. Los hallazgos indican que la separación de la diada durante la hospitalización impone limitaciones, que impiden que la mujer asuma con tranquilidad y alegría el nuevo rol. Es importante empoderar al personal de enfermería de las unidades neonatales para implementar estrategias de contacto temprano y continuo madre-hijo, que apoyen a las mujeres en el proceso de convertirse en madres.

No obstante, varias estrategias pueden reducir a un mínimo la transmisión nosocomial. Es imprescindible, por lo tanto, hacer que el personal de salud cobre mayor conciencia de que un individuo con sarampión puede llegar en cualquier momento a un servicio de salud y de que el peligro de transmisión del sarampión en el medio hospitalario existe de continuo. La presente revisión contiene dos grupos de recomendaciones: las que suelen ser aplicables a todos los países, y ciertas recomendaciones adicionales que pueden ser apropiadas solamente para países industrializados.

Los factores de riesgo tenidos en cuenta en 133 prematuros del ";Programa madre canguro"; del Instituto de los Seguros Sociales, en Medellín, fueron: Peso inferior a 1.500 g, hiperbilirrubinemia superior a 10 mg/ml, sufrimiento fetal, membranas hialinas, uso de aminoglicósidos, hipoglucemia, hemorragia del tercer trimestre e hipertensión arterial materna. Se halló pérdida de la agudeza auditiva en la evaluación inicial en 54 nifíos (40.6% mientras en la final sólo la presentaban 10 (7.5%; no pudo detectarse asociación entre los factores de riesgo y la disminución de la agudeza auditiva en la evaluación inicial ni en la final. La mejoría de resultados de agudeza auditiva entre las pruebas iniciales y las finales puede explicarse, entre otras razones, por la maduración cerebral del prematuro.

Full Text Available Introduction: Acute lower respiratory infections cause high morbidity and mortality in children. Respiratory syncytial virus (RSV is the most prevalent agent. Some viruses cause serious nosocomial infections. In Uruguay, there is no knowledge about the morbidity and mortality of nosocomial infections by RSV. Objective: To determine the prevalence and characteristics of RSV nosocomial infections. Methodology: A descriptive study of acute lower respiratory infections caused by RSV in patients younger than two years, between 1/1/2005 and 31/12/2008 at the Hospital Pediátrico del Centro Hospitalario Pereira Rossell, was made. Results: Were identified 59 patients who represented an annual rate lower than 2/1000 discharges. The monthly distribution of cases was similar to the respiratory infections. No outbreaks were reported. The age of the patients had an average of 8.9 months, 39 were younger than one year, 23 had one or more risk factors for severe disease. Six patients required admission to intensive care unit, all required invasive ventilation, 3 died, none had chronic respiratory failure following the RSV nosocomial infection. Conclusions: During the study period, the RSV nosocomial infections showed a low prevalence, despite it highly contagiousness. They mainly affected young children, carriers of risk factors for severe ALRI. Their evolution was similar to that reported for RSV respiratory infections community acquired. It is important to maintain standards for the control of nosocomial infections, to prevent nosocomial transmission of RSV and prevent the onset of severe disease in hospitalized patients.

Su frecuencia y gravedad aumentan en la medida en que es menor el peso al nacimiento; se la halla entre 10 y 20% de los neonatos de 1.000-1.500 gramos y hasta en 70% en los menores de 700 gramos; se presenta en 85% de las veces en las primeras 72 horas posparto y en 95% ya es evidente al finalizar la primera semana; son múltiples los factores maternos y fetales que se han encontrado asociados con el aumento o disminución de su frecuencia, además del uso de algunos medicamentos. Se han propuesto diversos mecanismos fisiopatogénicos asociados a la inmadurez neurológica para explicar la aparición de la HIV. Las manifestaciones clínicas son variables en cuanto a presentación y evolución. La confirmación diagnóstica, la clasificación y el pronóstico se basan en la ecografía transfontanelar. La principal medida preventiva es la disminución de la frecuencia del parto prematuro; los resultados de otras medidas como el uso prenatal y posnatal de algunos medicamentos para evitarla y tratarla han sido variables. El pronóstico depende de la extensión de la hemorragia, del desarrollo de leucomalacia periventricular y del grado de dilatación ventricular. Neonatal intraventricular hemorrage (IVH is the main neurological complication in preterm infants involving bleeding into the germinal matrix and the periventricular brain areas.

Full Text Available This qualitative study aims to identify and analyze the meanings the health team attributes to the parents' participation in the care of premature children hospitalized at a public hospital. Data were recorded and collected through semi-structured interviews performed with 23 professionals. The results show that parents' participation in the care of these children is still in an initial stage at the hospital's neonatal unit. However, there is interest from the health team to implement it because its importance is recognized in improving the clinical stability, the growth and development process of premature children. In addition to allowing for mother-child interaction and affective bonding, it prepares the mother for the child's discharge. The presence of the mother helps the nursing team by giving maternal care to the hospitalized child. On the other hand, the parents' presence interferes in the environment of the neonatal unit. It affects the work dynamics and creates insecurity among team workers, who feel supervised. Besides, there is concern regarding hospital infection. Thus, in accordance with other studies from different countries, these meanings entail reflections on the need to base the premature care in terms of collectively building a care philosophy that restores concepts of human rights, citizenship, bonding and mother-child attachment, pediatric psychology and also expands the concept of training for a participative health education.El estudio tiene como objetivo identificar y analizar los significados atribuidos por el equipo de salud con relación a la participación de la madre/padre en el cuidado del niño prematuro hospitalizado en un hospital público.

CONCLUSIÓN: Frente a los resultados positivos de este estudio, se recomienda que los programas educativos de esa naturaleza y ampliados con la participación de otros miembros de la familia del prematuro sean implantados en otras unidades neonatales.OBJECTIVE: To identify the perceptions of mothers of premature babies regarding their experience with a health educational program using participant observation methodology. METHODS: Thirty-eight mothers of inpatient premature babies of a neonatal unit participated in the health educational program. The goal of the educational program was to provide mothers with the knowledge and skills to care for their premature babies. Paulo Freire's theory of education served as the framework for the study. An educational booklet and group activities were used to stimulate mothers' perceptions regarding the educational program. A thematic analysis was used to identify the perceptions of mothers regarding the educational program through participants' talk. RESULTS: Four themes emerged: The development of mothers' knowledge by participating in the educational program; the potential for mothers to share the acquired knowledge with family members; the education program as a medium and place for relaxing and listening; and the development of an affective bond with other mothers and the nurse. CONCLUSION: Given the positive results of this study, it is recommended that such educational programs in neonatal units expand to include the participation of other family members or premature babies as well.

Full Text Available The care of critically ill patients in the intensive care unit (ICU is a primary component of modern medicine. ICUs create potential for recovery in patients who otherwise may not have survived. However, they may suffer from problems associated with of nosocomial infections. Nosocomial infections are those which manifest in patients 48 hours after admission to hospital. Nosocomial infections are directly related to diagnostic, interventional or therapeutic procedures a patient undergoes in hospital, and are also influenced by the bacteriological flora prevailing within a particular unit or hospital. Urinary tract infections are the most frequent nosocomial infection, accounting for more than 40% of all nosocomial infections. Critical care units increasingly use high technology medicine for patient care, hemodynamic monitoring, ventilator support, hemodialysis, parenteral nutrition, and a large battery of powerful drugs, particularly antibiotics to counter infection. It is indeed a paradox that the use of high-tech medicine has brought in its wake the dangerous and all too frequent complication of nosocomial infections

Full Text Available La prematuridad es una problemática que se encuentra en aumento a nivel mundial. En Argentina 8 de cada 100 bebés nacen antes de tiempo, de ahí la importancia de sensibilizar a la población sobre este tema. Para la logoterapia la motivación básica y propia del ser humano es su orientación fundamental hacia el sentido, es de- cir, el encontrar y descubrir un porqué y para qué. Tener en cuenta la dimensión existencial de la persona es una forma de acercarnos al problema. Por tal motivo el objetivo del trabajo que se in forma fue relacionar el sentido de vida develado por las madres de niños que se encuentran internados en Unidad de Cuidados Intensivos Neona- tales (UCIN debido a su nacimiento prematuro con dos factores; por un lado con la capacidad que ellas mismas refieren para informarse adecuadamente acerca de la situación de su hijo y por el otro, con su vinculación con situaciones límite vividas durante el embarazo. Se realizó un estudio experimental con 30 madres de niños prematuros que han pasado por una internación en UCIN en tres instituciones hospitalarias. Se construyó un instrumento con formato de entrevista semidirigida llamado Vivencia de Madres de Niños Nacidos Prematuramente. Los resultados demuestran que las madres con mayor capacidad para solicitar información sobre la situación de sus hijos son las que pudieron dar respuestas acerca de la pregunta sobre el sentido que esta situación les permitía descubrir. En un porcentaje menor pudieron relacionarse las respuestas con situaciones límites vividas con anterioridad.

Full Text Available Nosocomial pneumonia is the most common nosocomial infection in intensive care units. Rational antibiotic therapy is the basis for the treatment of nosocomial pneumonia. There is currently a challenge of the pathogens of nosocomial pneumonia being resistant to most of the antibiotics recommended for its treatment. Inhaled antibiotics used in combination with systemic drugs are an effective and safe treatment for nosocomial pneumonia. This review of literature characterizes the current possibilities of inhaled antibiotic therapy for nosocomial pneumonia in detail and describes medicaments and the advantages and disadvantages of this treatment option. Despite insufficient evidence in circumstances where the microorganisms are polyresistant and where the design of novel antibiotics shows no promise, the use of inhaled antibiotics is an important alternative in the treatment of severe nosocomial pneumonia caused by polyresistant gram-negative bacteria. Key words: nosocomial pneumonia, antibiotic therapy, inhaled antibiotics, resistance.

Se han encontrado otros factores asociados con el aumento o disminución de su frecuencia. Objetivo: determinar la incidencia de HIV en prematuros atendidos en el Hospital Universitario San Vicente de Paúl (HUSVP, de Medellín, Colombia, entre 1999 y 2004 y establecer su asociación con condiciones de la madre y del recién nacido. Metodología: estudio retrospectivo de los prematuros menores de 32 semanas y por debajo de 1.500 gramos, atendidos en el HUSVP entre 1999 y 2004. Se calculó una muestra de 330 historias clínicas, seleccionadas en forma aleatoria, con un nivel de confianza de 95%, error del 3% y poder del 80%,con base en una incidencia del 15% de HIV en la población general. Resultados: la incidencia encontrada de HIV fue 29,8%. Como factores protectores se encontraron los siguientes: parto por cesárea, parto en un centro de tercer nivel y maduración pulmonar. Como factores que aumentaron el riesgo de HIV se encontraron: parto vaginal, edad gestacional menor de 28 semanas, uso de surfactante, ventilación mecánica, cateterismo umbilical, acidosis e hipercapnia. Conclusiones: se debe insistir en la importancia de que haya programas adecuados de control prenatal para tratar de disminuir la frecuencia de parto prematuro, procurar la remisión oportuna de las gestantes de alto riesgo a centros de referencia, estimular el uso antenatal de esteroides y el control cuidadoso de los parámetros ventilatorios en los pacientes que requieran este soporte, buscando mantener un adecuado equilibrio ácido-base en los recién nacidos.

Full Text Available Nosocomial infections are also known as hospital-acquired/associated infections. National Healthcare Safety Network along with Centers for Disease Control for surveillance has classified nosocomial infection sites into 13 types with 50 infection sites, which are specific on the basis of biological and clinical criteria. The agents that are usually involved in hospital-acquired infections include Streptococcus spp., Acinetobacter spp., enterococci, Pseudomonas aeruginosa, coagulase-negative staphylococci, Staphylococcus aureus, Bacillus cereus, Legionella and Enterobacteriaceae family members, namely, Proteus mirablis, Klebsiella pneumonia, Escherichia coli, Serratia marcescens. Nosocomial pathogens can be transmitted through person to person, environment or contaminated water and food, infected individuals, contaminated healthcare personnel's skin or contact via shared items and surfaces. Mainly, multi-drug-resistant nosocomial organisms include methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Pseudomonas aeruginosa and Klebsiella pneumonia, whereas Clostridium difficile shows natural resistance. Excessive and improper use of broad-spectrum antibiotics, especially in healthcare settings, is elevating nosocomial infections, which not only becomes a big health care problem but also causes great economic and production loss in the community. Nosocomial infections can be controlled by measuring and comparing the infection rates within healthcare settings and sticking to the best healthcare practices. Centers for Disease Control and Prevention provides the methodology for surveillance of nosocomial infections along with investigation of major outbreaks. By means of this surveillance, hospitals can devise a strategy comprising of infection control practices.

Epidemiology of nosocomial infections in neonates has to be described according to our definitions (early onset GBS diseases excluded) and according to levels of care. Nosocomial risk exists in maternity departments (3% in postnatal beds), incidence rates are 7.5-12.7% or 1.3-8.5 per 1000 days in neonatal care units and 14.2% or 11.7 per 1000 days in neonatal intensive care units (NICU). Gram-positive cocci bloodstream infections are the most common nosocomial infections in NICU but viral gastroenteritis are more frequent in neonatal care units. Risk factors are low birthweight, small gestational age and intravascular catheter in NICU, and for viral nosocomial infections, visits and winter outbreaks.

Full Text Available O objetivo principal para o uso de uterolíticos no trabalho de parto prematuro é prolongar suficientemente a gestação para a administração materna de glicocorticoides e/ou realizar a transferência materna para um centro hospitalar terciário. As decisões sobre o uso e a escolha de uterolítico requerem o diagnóstico correto do trabalho de parto prematuro, o conhecimento da idade gestacional, das condições médicas materno-fetais, da eficácia, dos efeitos colaterais e do custo do medicamento. Todos os uterolíticos possuem efeitos colaterais e alguns deles são potencialmente letais. Os estudos sugerem que os agonistas de receptores beta-adrenérgicos, os bloqueadores de cálcio e os antagonistas de receptor de ocitocina são eficazes para prolongar a gestação por pelo menos 48 horas. Dos três agentes, o atosiban (antagonista de receptor de ocitocina possui maior segurança, embora o custo seja elevado. O sulfato de magnésio não é eficaz para prolongar a gestação e apresenta efeitos colaterais importantes. Os inibidores da ciclooxigenase também apresentam efeitos colaterais significativos. Até o momento, não há evidências suficientes para se recomendar o uso de doadores de óxido nítrico para inibir o trabalho de parto prematuro. Não existem fundamentos para o emprego de antibióticos para evitar a prematuridade diante do trabalho de parto prematuro.The main purpose of using uterulytic in preterm delivery is to prolong gestation in order to allow the administration of glucocorticoid to the mother and/or to accomplish the mother's transference to a tertiary hospital center.

With increasing use of antimicrobial agents and advance in lifesaving medical practices which expose the patients for invasive procedures, are associated with the ever increasing of nosocomial infections. Despite an effort in hospital infection control measures, health care associated infections are associated with significant morbidity and mortality adding additional health care expenditure which may leads to an economic crisis. The problem is further complicated with the emergence of difficult to treat multidrug resistant (MDR) microorganism in the hospital environment. Virtually every pathogen has the potential to cause infection in hospitalized patients but only limited number of both gram positive and gram negative bacteria are responsible for the majority of nosocomial infection. Among them Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Enterococci takes the leading. Many intrinsic and extrinsic factors predispose hospitalized patients for these pathogens. Following simple hospital hygienic practices and strictly following standard medical procedures greatly reduces infection to a significant level although not all nosocomial infections are avoidable. The clinical spectrum caused by nosocomial pathogens depend on body site of infection, the involving pathogen and the patient's underlying condition. Structural and non structural virulence factors associated with the bacteria are responsible for the observed clinical manifestation. Bacteria isolation and characterization from appropriate clinical materials with antimicrobial susceptibility testing is the standard of laboratory diagnosis.

Nosocomial Infections in Nuclear Medicine Departments: some considerations

International Nuclear Information System (INIS)

Metello, L.F.; Cunha, L.; Martins, M.; Isabel, O.; Ribeiro, G.

2002-01-01

Aim: Surveillance for Nosocomial Infection has become an integral part of hospital practice. Studies conducted more than 30 years ago by the Centers for Disease Control and Prevention (CDC) documented the efficacy of these surveillance activities in reducing Nosocomial Infection occurrence. It is clear that surveillance for Nosocomial Infection involves more than just documenting infection rates. However, many times the professionals involved have tended to stop at the point where rates are reported and fail to complete the task of implementing changes based on the analysis of rates or disseminating information. Moreover specific documentation regarding Nuclear Medicine Departments is not available. We therefore decided to produce this work based in the recognition of this specific need. Methods and Conclusions: Having previously defined the 'state-of-the-art' from science and technology concerning Nosocomial Infection Control and after particular study regarding technical/clinical reality of Nuclear Medicine Departments, namely introducing the radioactivity as a factor that must be taken into account with all its implications and interactions, we have obtained a group of considerations and/or recommendations to be considered in order to accomplish the maximum Quality and Efficiency regarding the Control of Nosocomial Infection in Nuclear Medicine Departments

According to §6, section 3 of the German Protection against Infections Act [Infektionsschutzgesetz (IfSG)] an outbreak is defined as the occurrence in large numbers of nosocomial infections for which an epidemiological relationship is probable or can be assumed. About 2-10% of nosocomial infections in hospitals (about 5% in intensive care wards) occur within the framework of an outbreak. The heaped occurrence of nosocomial infections can be declared according to the prescribed surveillance of nosocomial infections (§23 IfSG) when, in the course of this assessment, a statistically significant increase in the rate of infections becomes apparent. On the other hand, the occurrence of an outbreak can also be recognized through the vigilance of all involved personnel and a general sensibilization towards this subject. The names of patients involved in outbreaks need not be reported to the responsible health authorities. As a consequence of the report the health authorities become involved in the investigation to determine the cause and its elimination, and to provide support and advice. The outbreak management should be oriented on the respective recommendations of the Robert Koch Institute. © Georg Thieme Verlag Stuttgart · New York.

Full Text Available Objective: to evaluate the efficiency of an extended package of preventive measures on the incidence of nosocomial respiratory infections in surgical patients at an intensive care unit (ICU. Subjects and methods. The study included 809 patients aged 35 to 80 years. A study group comprised 494 patients in whom an extended package of preventive measures was implemented during 7 months (March-September. A control group consisted of 315 patients treated in 2004 in the same period of time (March-September. The groups were stratified by age, gender, underlying diseases, and APACHE-2 and SOFA scores. The extended package of anti-infectious measures involved a high air purification in ICUs («Flow-M» technology, routine use of ventilatory filters, closed aspiration systems with a built-in antibacterial filter under artificial ventilation for over 2 days. Results. The proposed technologies could reduce the frequency of tracheobronchitis and ventilator-associated pneumonias in the groups of patients at high risk for nosocomial infections substantially (by more than twice. Conclusion. The findings have led to the conclusion that the extended package of preventive measures is effective in preventing respiratory infections in ICU patients. Of special note is the proper prevention of upper airway contamination with pathogenic microorganisms, by employing the closed aspiration systems with a built-in antibacterial filter. The routine use of high-tech consumables in the intensive care of surgical patients causes a considerable decrease in the incidence of nosocomial pneumonia, ventilator-associated pneumonia, and purulent tracheobronchitis and a reduction in the number of microbiological studies. Key words: ventilator-associated pneumonia, prevention of nosocomial infections, closed aspiration system.

Rotavirus is the most common cause of gastroenteritis in children requiring hospitalization. It is a very resistant and contagious virus causing nosocomial gastroenteritis. In France, the vaccine against rotavirus has been available since 2006, but the vaccine is not recommended for infant vaccination. The aim of this retrospective study was to describe nosocomial rotavirus gastroenteritis (NRGE) and to assess its impact on children hospitalized in the General Pediatrics Department of Robert-Debré Hospital (Paris) between 1 January 2009 and 31 December 2013. We analyzed the demographic characteristics of children (age, term birth, underlying diseases) and the severity of the NRGE (oral or intravenous hydration), and assessed whether these children could benefit from vaccination against rotavirus. One hundred thirty-six children presented nosocomial rotavirus infection, with an incidence of 2.5 NRGE per 1000 days of hospitalization. The incidence of NRGE was stable between 2009 and 2013 despite the introduction of specific hygiene measures. The average age of the children was 7 months (range: 0.5-111 months). Most often NRGE occurred in children hospitalized for respiratory diseases (65% of cases) and requiring prolonged hospitalization (median: 18 days). One-third of children were born premature (25%). Hydration was oral in 80 patients (59%), by intravenous infusion in 18 patients (13%), and intraosseous in one patient. Half of the patients were aged less than 5 months and could benefit from the protection afforded by vaccination. NRGE are common. Rotavirus mass vaccination should have a positive impact on the incidence of NRGE by reducing the number of children hospitalized for gastroenteritis, therefore indirectly reducing the number of hospital cross-infections of hospitalized children who are too young to be vaccinated.

Nosocomial bloodstream infection in a tertiary care paediatric intensive care unit

International Nuclear Information System (INIS)

Hamid, M.H.; Maqbool, S.

2007-01-01

To determine the frequency, causative organisms and susceptibility pattern of nosocomial bloodstream infections in children. All children admitted to the unit during the study period were daily evaluated for features suggestive of nosocomial infection. In addition to other investigations, blood cultures were done in all suspected cases for the confirmation of nosocomial bloodstream infection (BSI). Nosocomial infection was defined according to the criteria set by Centre for Disease Control and Prevention. Demographic, microbiological and other variables were carefully studied to analyze frequency, incidence rate, spectrum of isolates and susceptibility pattern. Children with and without nosocomial BSI were compared with regard to age, duration of stay in hospital, need and duration of ventilation and the outcome. Of the total 406 admissions, 134 children were suspected to have nosocomial infection on at least 214 occasions (episodes). Blood cultures yielded growth of pathological organisms in 62 of these episodes, giving the frequency of nosocomial BSI as 15.2 per 100 admissions (62/406 episodes). Children with nosocomial bloodstream infection were found to have younger mean age (2.1 vs. 4.1 years), longer average duration of stay (13.1 vs. 6.6 days), more frequent need for ventilation (64% vs. 34%) and longer duration of ventilation (9.7 vs. 4.8 days). Majority of isolates (77%) were gram-negative bacteria; Klebsiella being the most common isolate (n= 23). Aztreonam, Ceftiazidime, Ceforuxime and Ciprofloxacin showed high resistance pattern (33-50%). Isolates showed good sensitivity to Vancomycin (100%), Imipenem (80%), Meropenem (100%) and Co-amoxiclav (88%). The frequency of nosocomial BSI in the observed setting was quite high, having marked impact on the duration of stay and outcome. Emergence of resistant pathogens is alarming. (author)

Full Text Available Nosocomial infections which are considered as the primary indicator of the quality of care in hospitals, cause to prolong hospitalization at intensive care unit and hospital, increase morbidity, mortality, and the cost of treatment. Although only 5-10% of the patients are treated in the intensive care units, 20-25% of all nosocomial infections are seen in these units. Preventing nosocomial infections in intensive care units is a process started at the patient acceptance to unit that requires an interdisciplinary team approach of intensive care staffs’ and Infection Control Committee members.Intensive care nurses who are in constant contact with patients have important responsibilities in preventing nosocomial infections. Intensive care nurses should be aware that the nosocomial infections can be prevented. They should have current knowledge about universal precautions related to prevention and control of infections, which are accepted by the entire world and they reinforce this knowledge by practice and should provide the most effective care to patients.In this article, nursing practices for prevention of nosocomial infections in intensive care units are discussed based on universal precautions.

Nosocomial infections can be prevented by applying simple hygiene rules. However, they have not been sufficiently studied in the Republic of Guinea. For this purpose, we conducted a one-day study in the Conakry University Hospital surgery wards and intensive care units. Fourteen units (12 surgical wards and 2 intensive care units) participated in the study. A total of 310 patients were included. A nosocomial infection was observed in 62 patients, [20%, 95%CI 15.9-24.8%]. Surgical site infections were significantly more frequent with 42/62 cases [67.7%, 95%CI 55.3-78.1%, p = 0.0001] than other types of infections (urinary tract, skin and digestive) with 20/62 cases [32.3% 95%CI 21.9-44.6%]. The average hospital stay of 29.1 ± 23.4 days [95%CI, 23.2 ± 35.04] for patients with nosocomial infection was significantly different (p = 0.0001) from that observed in patients without nosocomial infection: 15.9 ± 16.3 days [95%CI, 13.8 ± 17.9]. Staphylococcus aureus was the pathogen most commonly isolated: 32/62 (51.6%; 95%CI 39.5-63.6%). Escherichia coli infection was identified in the bladder catheters of 13 patients [20.9%, 95%CI 12.7-32.6%]. Finally, five deaths were observed among the 62 patients with nosocomial infection. This study shows that nosocomial infections are common in Conakry University Hospital. Further studies must be conducted to identify the risk factors for nosocomial infections and to propose solutions.

Full Text Available FUNDAMENTO: Várias publicações têm demonstrado a importância do sistema nervoso autônomo por meio dos componentes simpático e parassimpático na gerência da interação entre as diferentes partes do organismo humano. Esses estudos aplicaram técnicas lineares e não lineares (Teoria do Caos de avaliação em diferentes situações, doenças e faixas etárias, tendo como ferramenta a variabilidade da frequência cardíaca (VFC. OBJETIVO: Aplicar os conhecimentos das dinâmicas linear e não linear na avaliação de neonatos prematuros (NPT, analisando sua VFC e comparando com neonatos de termo (NT saudáveis. MÉTODOS: Quarenta e oito neonatos prematuros com diferentes idades gestacionais tiveram seus batimentos cardíacos captados com auxílio do equipamento Polar Advanced S810i e sua VFC obtida pelo registro dos intervalos RR. A VFC foi analisada nos domínios do tempo (SDNN, RMSSD, SD1/SD2, da frequência (VLF, LF, HF e a relação LF/HF e do caos (TAU e sua normalização [TAU(n], Expoente de Lyapunov e Entropia. Os NPT foram comparados com um grupo de 78 NT saudáveis e sem intercorrências perinatais com auxílio do teste não paramétrico de Kruskal-Wallis. RESULTADOS: Detectou-se diferença estatisticamente significante entre os grupos para todas as variáveis estudadas, tanto no domínio do tempo como nos da frequência e do caos. CONCLUSÃO: Neonatos prematuros exibem comportamento menos complexo da variabilidade da frequência cardíaca que neonatos de termo, fato comprovado nos domínios do tempo, da frequência e do caos. O estudo da variabilidade cardíaca nesse grupo pode ser considerado uma ferramenta a mais na avaliação da maturação autonômica e, consequentemente, da progressão para eutrofia.

Pediatric mortality due to nosocomial infection: a critical approach

Directory of Open Access Journals (Sweden)

Julia Marcia Maluf Lopes

Full Text Available Nosocomial infection is a frequent event with potentially lethal consequences. We reviewed the literature on the predictive factors for mortality related to nosocomial infection in pediatric medicine. Electronic searches in English, Spanish and Portuguese of the PubMed/MEDLINE, LILACS and Cochrane Collaboration Databases was performed, focusing on studies that had been published from 1996 to 2006. The key words were: nosocomial infection and mortality and pediatrics/neonate/ newborn/child/infant/adolescent. The risk factors found to be associated with mortality were: nosocomial infection itself, leukemia, lymphopenia, neutropenia, corticosteroid therapy, multiple organ failure, previous antimicrobial therapy, catheter use duration, candidemia, cancer, bacteremia, age over 60, invasive procedures, mechanical ventilation, transport out of the pediatric intensive care unit, methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, and Burkholderia cepacia infections, acute physiology and chronic health evaluation (APACHE II scores over 15. Among these factors, the only one that can be minimized is inadequate antimicrobial treatment, which has proven to be an important contributor to hospital mortality in critically-ill patients. There is room for further prognosis research on this matter to determine local differences. Such research requires appropriate epidemiological design and statistical analysis so that pediatric death due to nosocomial infection can be reduced and health care quality improved in pediatric hospitals.

Full Text Available Nosocomial infection are one of the main problem in hospital which are associated with significant morbidity, mortality and increased economic cost. Surveillance should be attempted regularly to obtain local data of incidence of nosocomial infections, types of infection, pathogen and resistance pattern. We reported the results of nosocomial surveillance in Dr. Cipto Mangunkusumo National General Hospital, Jakarta, in year 1999 to 2002. The data were obtained from surveillance, conducted by Nosocomial Infection Control Committee. Surveillance were performed to patient in risk of nosocomial infections such as underwent surgical procedure, urinary catheter, peripheral or central venous catheter, ventilator and other invasive procedure. Criteria for nosocomial infection which were used, based on technical guidelines of nosocomial infection in Dr. Cipto Mangunkusumo National General Hospital, year 1999; which referred to CDC definition of nosocomial infections. Incidence rate of nosocomial infections in year 1999, 2000, 2001 and 2002 were 1.1, 0.9, 0.6 and 0.4 % respectively. Type of nosocomial infection include catheter related, surgical wound, urinary tract and respiratory tract infections, ranged between 0 to 5.6 %. Gram negative bacteria consist of Pseudomonas sp, Enterobacter aerogenes, Escherichia coli, Proteus mirabilis were the most common nosocomial pathogen. Gram positive bacteria consist of Staphylococcus epidermidis, Staphylococcus aureus and Streptococcus anhemolyticus. Trend of increasing incidence of Gram positive nosocomial infection also showed in our surveillance. Mostly Gram negative bacteria had been resistant to penicillin, co amoxicillin-clavulanic acid and 3rd generation cephalosporin, but still sensitive to 4th generation cephalosporin and aminoglycoside. The Gram positive bacteria were still sensitive to penicillin, co amoxicillin-clavulanic acid, 4th generation cephalosporin and aminoglycoside. (Med J Indones 2004; 13: 107

Conclusiones: La prevalencia acumulada de ROP severa fue de 20.2%, semejante a la de otros países de Latinoamérica. La prevalencia elevada desde 2005 hasta 2009 es explicada por la evaluación de prematuros externos manejados en instituciones sin tamizaje para ROP y referidos solo para su evaluación oftalmológica. Detectamos un descenso en la prevalencia a partir de 2010, que incluyó únicamente pacientes tratados en nuestra institución. De 2011 a 2014 no se reportaron niños con ceguera por ROP.

Full Text Available Abstract Background Many studies associated nosocomial infections with increased hospital costs due to extra days in hospital, staff time, extra investigations and drug treatment. The cost of antibiotic treatment for these infections represents a significant part of hospital expenditure. This prospective observational study was designed to determine the daily antibiotic cost of nosocomial infections per infected adult patient in Akdeniz University Hospital. Methods All adult patients admitted to the ICUs between January 1, 2000, and June 30, 2003 who had only one nosocomial infection during their stay were included in the study. Infection sites and pathogens, antimicrobial treatment of patient and it's cost were recorded. Daily antibiotic costs were calculated per infected patient. Results Among the 8460 study patients, 817 (16.6% developed 1407 episodes of nosocomial infection. Two hundred thirty three (2.7% presented with only one nosocomial infection. Mean daily antibiotic cost was $89.64. Daily antibiotic cost was $99.02 for pneumonia, $94.32 for bloodstream infection, $94.31 for surgical site infection, $52.37 for urinary tract infection, and $162.35 for the other infections per patient. The treatment of Pseudomonas aeruginosa infections was the most expensive infection treated. Piperacillin-tazobactam and amikacin were the most prescribed antibiotics, and meropenem was the most expensive drug for treatment of the nosocomial infections in the ICU. Conclusions Daily antibiotic cost of nosocomial infections is an important part of extra costs that should be reduced providing rational antibiotic usage in hospitals.

Full Text Available A necessidade de intubação e do uso de ventilação mecânica na prematuridade está relacionada à chamada lesão pulmonar induzida pela ventilação e à consequente displasia broncopulmonar. Busca-se a melhor compreensão dos mecanismos de lesão envolvendo resposta inflamatória mediada pelas citocinas para o desenvolvimento de novas estratégias protetoras. Pesquisou-se na base de dados PubMed, incluindo artigos relevantes, os unitermos "ventilator induced lung injury preterm", "continuous positive airway pressure", "preterm" e "bronchopulmonary dysplasia". Dados e informações significativas foram compilados em tópicos, com o objetivo de formar uma visão crítica e plena acerca da lesão induzida pela ventilação e de suas consequências ao prematuro. Foi revisado o papel das citocinas pró-inflamatórias como mediadores da lesão, especialmente interleucinas 6 e 8, e fator de necrose tumoral alfa. Foram apresentadas evidências em estudos com animais e também em humanos, mostrando que breves períodos de ventilação mecânica são suficientes para a liberação dessas interleucinas inflamatórias. Também foram revisadas outras formas de ventilação mecânica e de ventilação não invasiva, como alternativas protetoras aos modos convencionais. Concluiu-se que o uso de ventilação não invasiva, a intubação com administração precoce de surfactante e a extubação rápida para CPAP nasal, além de estratégias que regulam o volume corrente evitando o volutrauma (como a ventilação com volume garantido, são medidas protetoras da lesão pulmonar induzida pela ventilação mecânica no prematuro.

Full Text Available Background The CDC defines a nosocomial infection as a localized or systemic condition caused by an adverse reaction to the presence of an infectious agent(s or its toxin(s. It is an infection that occurs between 48 to 72 hours after admission of patients in the hospital or as soon after the hospital discharge and on the admission time, patients don't have this infection. Objectives This study aimed to characterize the prevalence of nosocomial infection in Ghaem hospital, Mashhad, Iran. Methods This retrospective study was conducted in all wards of the Ghaem hospital, Mashhad during the 1 year period (2013; the data were collected from the wards records and HIS system and analyzed by the SPSS software (version16. Results In the present study, of total 35979 hospitalized patients in different wards of the Ghaem hospital was reported 1.1% of nosocomial infection. In the meantime, overall, the most prevalent organism was Acinetobacter baumannii with a prevalence of 37.2% and the minimum was linked to the Bacillus species with a prevalence 0.3%. The highest and lowest prevalence of the nosocomial infection was in the ICU and CCU with 49.9% and 0.3%, respectively. In general, among all wards of the mentioned hospital, the most frequent nosocomial infection was pneumonia (47.4% and the lowest belonged to CSF (2.3%. Conclusions In our study, the ICU ward was accounted for the highest rate of nosocomial infection, due to the critical importance of this ward.

Full Text Available OBJETIVO: O aumento da sobrevida de prematuros traz o desafio de lidar com um amplo espectro de doenças pulmonares crônicas, incluindo displasia broncopulmonar, síndrome de Wilson-Mikity e sibilância recorrente. Este artigo discute o prognóstico pulmonar clínico e funcional de prematuros na infância e na adolescência. FONTE DE DADOS: Foi realizada pesquisa no MEDLINE de publicações entre 1970 e 2004 que abordassem função e crescimento pulmonar de prematuros, bem como a evolução clínica dos mesmos. SÍNTESE DOS DADOS: Eventos pré e pós-natais como insuficiência placentária, tabagismo, infecções, oxigênio e ventilação mecânica exercem efeitos importantes no desenvolvimento pulmonar, podendo conduzir a doenças pulmonares crônicas, sendo a displasia broncopulmonar a complicação clínica mais severa. No entanto, perdas significativas de função pulmonar também podem ocorrer em prematuros sem critérios de displasia broncopulmonar e que não apresentaram doença respiratória neonatal significativa. Nestes pacientes, o impacto da prematuridade sobre o sistema respiratório é freqüentemente subestimado. Clinicamente, observa-se incidência aumentada de pneumonias e bronquiolites, re-hospitalizações por doenças respiratórias, tosse e sibilância crônicas e hiper-reatividade brônquica. Posteriormente, percebe-se uma tendência à normalização da função pulmonar, mas persistem fluxos reduzidos, menor tolerância a exercícios e hiper-reatividade brônquica. CONCLUSÕES: A prematuridade, os eventos que a provocam e as intervenções que dela decorrem alteram de maneira permanente, em maior ou menor grau, o desenvolvimento do sistema respiratório. São necessários estudos adicionais para esclarecer o efeito de cada um desses insultos perinatais no desenvolvimento do sistema respiratório.OBJECTIVE: The increased survival of preterm infants poses the challenge of dealing with a wide range of chronic pulmonary

1992-01-01

Full Text Available From 1981 to 1991, 55 patients (33 males, 22 females, mean age 58.6 years with nosocomial Legionnaires’ disease were studied. The mortality rate was 64%. One-half of the patients developed nosocomial Legionnaires’ disease within three weeks of admission. A surprising clinical feature was the low rate of findings of consolidation on physical examination, despite the fact that 52% of patients had this finding on chest radiograph. More than one-half of patients had pre-existing lung disease, rendering a radiographic diagnosis of pneumonia due to Legionella pneumophila impossible in 16% of cases despite microbiological confirmation. Nineteen per cent of patients who had blood cultures done had a pathogen other than L pneumophila isolated, suggesting dual infection in at least some of the patients. When the clinical and radiographic findings were combined it was noted that 40% of patients had one of three patterns suggestive of nosocomial Legionnaires’ disease: rapidly progressive pneumonia, lobar opacity and multiple peripheral opacities. However, in 60% of patients there were no distinctive features.

Prevention of nosocomial infection is key to providing good quality, safe healthcare. Infection control programmes (hand-hygiene campaigns and antibiotic stewardship) are effective in reducing nosocomial infections in developed countries. However, the effectiveness of these programmes in developing countries is uncertain. To evaluate the effectiveness of interventions for preventing nosocomial infections in developing countries. A systematic search for studies which evaluated interventions to prevent nosocomial infection in both adults and children in developing countries was undertaken using PubMed. Only intervention trials with a randomized controlled, quasi-experimental or sequential design were included. Where there was adequate homogeneity, a meta-analysis of specific interventions was performed using the Mantel-Haenzel fixed effects method to estimate the pooled risk difference. Thirty-four studies were found. Most studies were from South America and Asia. Most were before-and-after intervention studies from tertiary urban hospitals. Hand-hygiene campaigns that were a major component of multifaceted interventions (18 studies) showed the strongest effectiveness for reducing nosocomial infection rates (median effect 49%, effect range 12.7-100%). Hand-hygiene campaigns alone and studies of antibiotic stewardship to improve rational antibiotic use reduced nosocomial infection rates in three studies [risk difference (RD) of -0.09 (95%CI -0.12 to -0.07) and RD of -0.02 (95% CI -0.02 to -0.01), respectively]. Multifaceted interventions including hand-hygiene campaigns, antibiotic stewardship and other elementary infection control practices are effective in developing countries. The modest effect size of hand-hygiene campaigns alone and negligible effect size of antibiotic stewardship reflect the limited number of studies with sufficient homogeneity to conduct meta-analyses.

Full Text Available Objetivos: os objetivos deste estudo foram verificar a frequência de positividade do T-ACE questionário durante a gravidez de mães de recém-nascidos prematuros comparados com as de termo, e avaliar a associação de álcool referido pelo teste com o tabagismo materno e paterno. Métodos: estudo tipo observacional, transversal, com recrutamento de forma sequencial de 142 puérperas de uma maternidade pública. Foram aplicados: entrevista para coleta de dados clínicos e sociodemográficos e T-ACE questionário. Os recém-nascidos de termo e prematuros destas mulheres foram avaliados em relação ao peso, comprimento e perímetro cefálico ao nascimento. Estudo aprovado pelo comitê de Ética local e a participação das mulheres foi mediante assinatura do termo de consentimento livre e esclarecido. A análise dos dados foi realizada usando o programa SPSS, sendo adotado nível de significância de 5%. Resultados: das puérperas entrevistadas 21,1% foram consideradas consumidoras de álcool pelo T-ACE questionário. Quando divididas entre puérperas de partos de termo e prematuros, encontraram-se 21% de positividade do T-ACE teste no grupo de termo e 21,3% no grupo dos prematuros (p = 0,98. Houve importante associação entre positividade do T-ACE questionário e tabagismo materno e paterno durante a gestação (p = 0,04. Conclusões: cerca de duas em cada dez gestantes apresentaram teste T-ACE positivo, sem diferença entre o grupo de parto de termo e prematuros. A associação encontrada entre o consumo de álcool e fumo durante a gravidez sugere a importância do rastreamento rotineiro do T-ACE questionário, tendo em vista que esses dois agentes potencializam efeitos adversos no feto.

Nosocomial infection is a common problem in neonatal intensive care. A pilot quality improvement initiative focussing on hand hygiene and aimed at reducing nosocomial infection in very low birth weight (VLBW) infants was introduced in five Neonatal Intensive Care Units. Line associated laboratory confirmed bloodstream infection (LCBSI) and ventilator associated pneumonia (VAP) were chosen as main outcome measures. In VLBW infants, the rate of line associated LCBSI per 1000 central venous catheter days fell by 24%. The rate of VAP per 1000 ventilator days in VLBW infants fell by 38%. Pre- and post-intervention questionnaires showed a statistically significant increase in use of alcohol-based gels and increased knowledge of hand hygiene.

Objective The main aim of this study was to assess the magnitude of NIs at the Clinical Centre in Kragujevac. Methods A prevalence study of nosocomial infections was conducted from 16th till 20th May, 2005, within Second National Prevalence Study of Niš in the Republic of Serbia. Results The study included 866 patients. 40 patients had a NI, thus the prevalence of patients with NIs and prevalence of NIs was the same, 4.6%. Among NIs, the most frequent were urinary infections (45.0% followed by surgical-site infections (17.5%, skin and soft tissue infections (15% and pneumonia (12.5%. The rate of NIs was highest at departments of orthopaedics and traumatological surgery (12.0%, followed by intensive care units (8.0%. Overall, 67.5% (27/40 NIs were culture-proved; the leading pathogens were Escherichia coli (40.0%, followed by gram-negative bacteria (Pseudomonas species, Proteus mirabilis, Enterobacteriaceae with equal frequency of 8.0%. Nosocomial infections were significantly more frequent in patients aged ≥65 years (p<0.05, with longer hospitalization ≥8 days (p<0.00, in intensive care patients (p<0.05, patients with an intravenous catheter (p<0.00, urinary catheter (p<0.00, and those under antibiotic therapy (p<0.00. Conclusion This study showed that the prevalence of nosocomial infections in our hospital is similar to the prevalence in the developed countries. The study of prevalence provides a prompt insight into basic epidemiological and ethiological characteristics of nosocomial infections, hence identification of hospital priorities and the need to undertake appropriate prevention measures. .

Full Text Available Introduction. Hospital infections are one of the most serious threats to the hospitalised patient and their monitoring is recognised as one of the most important criteria of care quality for modern hospitals. The aim of the work was to present the problem of nosocomial infections and desired behaviours and activities in the field of infection prophylaxis. Material and method. The analysis of the current scientific literature was carried out with particular attention to the prevention of infections in treatment wards and the need to monitor the patient's condition and the environment in the case of an infection. Results. The lack of developed and implemented programmes for the control of nosocomial infections is a fundamental element that increases the risk of nosocomial infections. This disrupts the proper functioning of the hospital and causes additional health problems for the patient and the ward staff. In addition, the hospital suffers losses instead of savings, which is a priority aim in the current funding system. Conclusions. The basis for eliminating or minimising the incidence of nosocomial infections is a well-developed and implemented programme of hospital infection control based on the education of medical personnel in the field of infection prevention. Constant, comprehensive assessment of the procedures used and the standards of conduct, epidemiological data as well as microbiological data can ensure quick identification and elimination of the threat.

Immunodepressed patients, particularly those with neutropenia or bone marrow or organ grafts, are at risk of developing nosocomial invasive pulmonary aspergilosis. The favoring factors, early diagnostic criteria and curative treatment protocols are well known. Prognosis remains however quite severe with a death rate above 50%. Preventive measures are required for the treatment of these high-risk patients and epidemiology surveillance is needed in case of aspergillosis acquired in the hospital.

Nosocomial infection with Listeria monocytogenes 4b occurred in January 1990 in a maternity hospital in Grenoble. The 3 patients involved were born within a 24 hour-interval. The premature newborn responsible for contamination was asymptomatic. Two other newborns without any perinatal infectious risk presented with meningitis, one on the 5th day of life in the maternity hospital, the other one on the 11th day while already at home. The 3 strains of Listeria had the same serovar and lysovar. Epidemiologic investigations led to suspect a contamination in the delivery room and during the care of the children. Strict respect of hygiene orders is imperative to avoid nosocomial infections.

Observational, descriptive and prospective study; by means of active vigilance all along 2014 in order to detect the nosocomial infections, for epidemiologic study, culture and antibiogram to identify its causal agents and antibiotics resistance and sensitivity. Among 13527 hospital discharges, 1079 displayed NI (8 %), standed out: the related on vascular lines, of surgical site, pneumonia and urinal track; they added up two thirds of the total. We carried out culture and antibiogram about 300 of them (27.8 %); identifying 31 bacterian species, mainly seven of those (77.9 %): Escherichia coli, Staphylococcus aureus and epidermidis, Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae and Enterobacter cloacae; showing multiresistance to 34 tested antibiotics, except in seven with low or without resistance at all: vancomycin, teicoplanin, linezolid, quinupristin-dalfopristin, piperacilin-tazobactam, amikacin and carbapenems. When we contrasted those results with the recommendations in the clinical practice guides, it aroused several contradictions; so they must be taken with reserves and has to be tested in each hospital, by means of cultures and antibiograms in practically every case of nosocomial infection.

Fueran entrevistadas 13 madres de recién nacidos prematuros, atendidas en Ambulatorio de Follow-up, municipio de Montes Claros - MG, Brasil. Los resultados revelaron que al intentar amamantar al hijo prematuro, la madre interacciona con situaciones significadas por ella como obstáculos al amamantamiento: el “tormento” de la hospitalización del hijo, su inestabilidad clínica, miedo de muerte del bebé, su dificultad en succionar el pecho, el inicio tardío del amamantamiento interpretado como algo difícil y riesgoso al gaño de peso. Consideramos que, aunque el proceso de amamantamiento del recién nacido prematuro sea un verdadero desafío, conductas profesionales y rutinas hospitalarias adecuadas facilitan la práctica y deben ser incentivadas.

Nosocomial pneumonia in the ICU--year 2000 and beyond.

Science.gov (United States)

Bowton, D L

1999-03-01

Diagnostic and treatment strategies in ICU patients with ventilator-associated pneumonia (VAP) remain controversial, largely because of the paucity of well-controlled comparison trials using clinically important end points. Recent studies indicating that early appropriate antibiotic therapy significantly lowers mortality underscore the urgent need for well-designed comparative trials. When quantitatively cultured, bronchial specimens obtained by noninvasive techniques may provide clinically useful information and avoid the higher costs and risks of invasive bronchoscopic diagnostic techniques. Previous antibiotic use before onset of nosocomial pneumonia raises the likelihood of infection with highly virulent organisms, such as Pseudomonas aeruginosa and Acinetobacter sp. Thus, the empiric antibiotic regimen should be active against these Gram-negative pathogens as well as other common Gram-negative and Gram-positive causative organisms. Promising preventive modalities for nosocomial VAP include use of a semirecumbent position, endotracheal tubes that allow continuous aspiration of secretions, and heat and moisture exchangers. Rotating their standard empiric antibiotic regimens and restricting the use of third-generation cephalosporins as empiric therapy may help hospitals reduce the incidence of nosocomial pneumonia caused by resistant Gram-negative pathogens.

Nursing care based on knowledge management is established from identification knowledge which is required, prevention performance of nosocomial infections post section caesarea. Nosocomial infections component consists of wound culture result. Method: This study was an observational study with a quasi experimental design. The population was all of nursing staff who working in obstetrics installation in hospitals A and B as much as 46 people. Sample was the total population. Data was collected through questionnaire, observation sheets and examination of the wound culture. Data was analyzed using t test B 1.274 dan p=0.028 Result: The result showed that 1 there was difference in knowledge management implementation before and after training; 2 there was difference in nurse’s performance in preventing nosocomial infection before and after training; 3 there is significant relationship between nurse’s performance in preventing nosocomial infection and infection incidence; 4 there is no significant difference of nursing care impementation on nosocomial incidence. Discussion: In conclusion, the development of nursing care based on knowledge management as a synthesis or induction of findings directed at 1 nurses’ knowledge does not affect the performance of the prevention of nosocomial infections; 2 knowledge management has a positive effect on the performance of the prevention of nosocomial infections; 3 implementation of infection prevention is integrated capabilities between knowledge, skills and attitudes of nurses in implementing performance in care.

British colleagues have developed the Outbreak Reports and Intervention studies of Nosocomial Infection (Orion) guidelines with the aim to promote transparency of publications in the field of health-care associated infections and particularly for reports of outbreak investigation or intervention studies. The aim of this study was to translate the Orion criteria and to promote their use in France. The Orion guidelines include a checklist of 22 commented items related to the title, abstract, introduction, methods, results, and discussion sections of a scientific article. Specific points for each item are developed to enhance its relevance. The use of Orion guidelines by authors and editors should be encouraged and should improve the quality of standards in research, intervention studies, and publications on nosocomial infections and health-care associated infections.

Foi realizado com 12 mães de recém-nascidos prematuros, em um hospital maternidade municipal do Rio de Janeiro, em 2007. Adotou-se como suporte metodológico a Fenomenologia Sociológica de Alfred Schutz. A Entrevista Fenomenológica foi a técnica utilizada para captar o contexto vivencial das mães na unidade hospitalar, compreendendo que a sua permanência está ligada à ação de cumprir seu papel de ser mãe. A vivência das mulheres é retratada como um processo difícil, triste e conflituoso. Concluímos que as mães atualmente estão presentes, mas não estão inseridas nesta realidade intensiva. Dessa forma, entendemos que é necessário mudar esse paradigma intensivista incorporando o cuidado humanizado, inserindo a mãe e sua família no ambiente neonatal.El presente estudio tuvo como objetivo comprender la razón por la cual la madre permanece en el hospital durante la hospitalización del bebé prematuro en la unidad de cuidados intensivos neonatal.

Full Text Available Background: Emergence of polyantimicrobial resistant strains of hospital pathogens has presented a challenge in the provision of good quality in-patient care. Inappropriate use of antibiotics in the hospital is largely responsible for this catastrophe. Bacteriological surveillance of the cases of nosocomial infections is crucial for framing an evidence-based antimicrobial policy for a hospital. Materials and Methods: A prospective study was undertaken among 498 patients from medicine and surgery wards in a tertiary teaching hospital in Goa. The patients were followed up clinico-bacteriologically for the occurrence of nosocomial infections (NI. Antibiotic susceptibility testing was done using Kirby-Bauer disc diffusion method. Results: The overall infection rate was 33.93 ± 4.16 infections per 100 patients. Urinary tract infection was the most common NI (26.63%, followed by surgical site infection (23.67%, wound infection (23% and nosocomial pneumonia (18.34%. Ninety-seven percent of the isolates were bacterial, while the others were fungal. More than 80% of the NIs were caused by Gram-negative bacteria, predominantly Pseudomonas aeruginosa, Escherichia coli and Aceinetobacter baumanii . Almost 70% of the isolates were resistant to all the antibiotics for which susceptibility was tested; the rest were sensitive to amikacin, cefoperazone-sulbactam and other antibiotics including methicillin, co-trimoxazole, teicoplenin, vancomycin and rifampicin, either singly or in combination. The proportion of MRSA was 71.4%. Resistance to a particular antibiotic was found to be directly proportional to the antibiotic usage in the study setting. Conclusion: Surveillance of nosocomial infections with emphasis on the microbiologic surveillance and frequent antimicrobial audit are critical towards curbing the evil of polyantimicrobial resistant nosocomial infections in a hospital.

To determine risk factors for nosocomial bloodstream infection (BSI) and associated mortality in geriatric patients in geriatric and internal medicine wards at a university hospital. Single-center retrospective (1992-2007), pairwise-matched (1:1-ratio) cohort study. Geriatric patients with nosocomial BSI were matched with controls without BSI on year of admission and length of hospitalization before onset of BSI. Demographic, microbiological, and clinical data are collected. One-hundred forty-two BSI occurred in 129 patients. Predominant microorganisms were Escherichia coli (23.2%), coagulase-negative Staphylococci (19.4%), Pseudomonas aeruginosa (8.4%), Staphylococcus aureus (7.1%), Klebsiella pneumoniae (5.8%) and Candida spp. (5.8%). Matching was successful for 109 cases. Compared to matched control subjects, cases were more frequently female, suffered more frequently from arthrosis, angina pectoris and pressure ulcers, had worse Activities of Daily Living-scores, had more often an intravenous or bladder catheter, and were more often bedridden. Logistic regression demonstrated presence of an intravenous catheter (odds ratio [OR] 7.5, 95% confidence interval [CI] 2.5-22.9) and being bedridden (OR 2.9, 95% CI 1.6-5.3) as independent risk factors for BSI. In univariate analysis nosocomial BSI was associated with increased mortality (22.0% vs. 11.0%; P=0.029). After adjustment for confounding co-variates, however, nosocomial BSI was not associated with mortality (hazard ratio 1.3, 95% CI 0.6-2.6). Being bedridden and increasing age were independent risk factors for death. Intravenous catheters and being bedridden are the main risk factors for nosocomial BSI. Although associated with higher mortality, this infectious complication seems not to be an independent risk factor for death in geriatric patients.

Bloodstream infections are the most frequent nosocomial infections in neonatal intensive care units. This retrospective study surveyed the epidemiologic characteristics of nosocomial bloodstream infections which occurred in the neonatal intensive care unit from January 1, 1997 to December 31, 1999. The overall infection patient rate was 5.5% in the 3-year period, and the overall infection patient-day rate was 4.4 per 1000 patient-days. Low birth weight was a risk factor for bloodstream infections. The rate of infection for neonates with birth weight below 1000 g ranged from 36.6% to 45.8% (1997: 36.6%; 1998: 45.8% and 1999: 38.9%). The most common pathogens causing nosocomial bloodstream infection were: Staphylococcus aureus (18.5%) (with 92% oxacillin-resistant), Acinectobacter baumannii (16.3%), Klebsiella pneumoniae (11.9%), Escherichia coli (9.6%), and Pseudomonas aeruginosa (8.1%). The mortality due to nosocomial bloodstream infection was highest among gram-negative bacteria, especially with P. aeruginosa (45.5%). Therefore, surveillance of nosocomial bloodstream infection and successful strategies to decrease nosocomial bloodstream infection, such as infection control and optimal antibiotic use, are warranted.

To estimate the incremental cost of nosocomial bacteremia according to the causative focus and classified by the antibiotic sensitivity of the microorganism.Patients admitted to Hospital del Mar in Barcelona from 2005 to 2012 were included. We analyzed the total hospital costs of patients with nosocomial bacteremia caused by microorganisms with a high prevalence and, often, with multidrug-resistance. A control group was defined by selecting patients without bacteremia in the same diagnosis-related group.Our hospital has a cost accounting system (full-costing) that uses activity-based criteria to estimate per-patient costs. A logistic regression was fitted to estimate the probability of developing bacteremia (propensity score) and was used for propensity-score matching adjustment. This propensity score was included in an econometric model to adjust the incremental cost of patients with bacteremia with differentiation of the causative focus and antibiotic sensitivity.The mean incremental cost was estimated at &OV0556;15,526. The lowest incremental cost corresponded to bacteremia caused by multidrug-sensitive urinary infection (&OV0556;6786) and the highest to primary or unknown sources of bacteremia caused by multidrug-resistant microorganisms (&OV0556;29,186).This is one of the first analyses to include all episodes of bacteremia produced during hospital stays in a single study. The study included accurate information about the focus and antibiotic sensitivity of the causative organism and actual hospital costs. It provides information that could be useful to improve, establish, and prioritize prevention strategies for nosocomial infections.

Hospital-acquired infections occur at an alarmingly high frequency, possibly affecting as many as 1 in 10 patients, resulting in a staggering morbidity and an annual mortality of many tens of thousands of patients. Appropriate hand hygiene is highly effective and represents the simplest approach that we have to preventing nosocomial infections. The Agency for Healthcare Research and Quality has targeted hand-washing compliance as a top research agenda item for patient safety. Recent research has identified inadequate hand washing and contaminated anesthesia workstation issues as likely contributors to nosocomial infections, finding aseptic practices highly variable among providers. It is vital that all healthcare providers, including anesthesia providers, appreciate the role of inadequate hand hygiene in nosocomial infection and meticulously follow the mandates of the American Association of Nurse Anesthetists and other professional healthcare organizations.

Full Text Available Background: Nosocomial infections are an important cause of mortality in neonatal intensive care units (NICUs. Therefore, in this study, the incidence and prevalence of nosocomial infections were determined in NICUs of the three largest neonatal centers in northwest Iran, and the causative bacteria were identified in order to provide potential solutions to control the infections in these hospitals. Materials and Methods: This is a descriptive-prospective study in which the cases of nosocomial infections were examined in the three largest hospitals in Tabriz in northwest Iran during 1 year (from June 2012 until May 2013 based on clinical findings, medical and nursing reports of patients, and laboratory results. Results: Of the 3129 patients hospitalized in NICUs of the three hospitals, 208 patients were diagnosed with nosocomial infections. The incidence rate of nosocomial infections was 11.34%.per 100 patient days with 52.4% bacteremia, 32.69% pneumonia, 5.77% urinary tract infections, 5.29% wound infections, and 3.85% necrotizing enterocolitis. There was a statistically significant relationship between invasive procedures (such as umbilical catheters, central venous catheters, surgery, and TPN and sepsis (P = 0.001. The relationships between urinary tract infection and urinary catheter (P = 0.000, and aggressive procedures (such as suctioning and intubation and pneumonia (P = 0.001 were also statistically significant. Conclusion: Incidence of nosocomial infections in premature and low birth weight newborns is considered as a health threat. The findings of this research reiterate the importance of giving further attention to prevention and control of nosocomial infections in the NICU.

Full Text Available Introduction. Pneumonia is the most frequent nosocomial infection in intensive care units. The reported frequency varies with definition, the type of hospital or intensive care units and the population of patients. The incidence ranges from 6.8-27%. Objective. The objective of this study was to determine the frequency, risk factors and mortality of nosocomial pneumonia in intensive care patients. Methods. We analyzed retrospectively and prospectively the collected data of 180 patients with central nervous system infections who needed to stay in the intensive care unit for more than 48 hours. This study was conducted from 2003 to 2009 at the Clinical Centre of Kragujevac. Results. During the study period, 54 (30% patients developed nosocomial pneumonia. The time to develop pneumonia was 10±6 days. We found that the following risk factors for the development of nosocomial pneumonia were statistically significant: age, Glasgow Coma Scale (GCS score <9, mechanical ventilation, duration of mechanical ventilation, tracheostomy, presence of nasogastric tube and enteral feeding. The most commonly isolated pathogens were Klebsiella-Enterobacter spp. (33.3%, Pseudomonas aeruginosa (24.1%, Acinetobacter spp. (16.6% and Staphylococcus aureus (25.9%. Conclusion. Nosocomial pneumonia is the major cause of morbidity and mortality of patients with central nervous system infections. Patients on mechanical ventilation are particularly at a high risk. The mortality rate of patients with nosocomial pneumonia was 54.4% and it was five times higher than in patients without pneumonia.

Full Text Available Myiasis is the infestation of living vertebrates or humans tissues by dipterous larvae. The oral cavity is rarely affected by this infestation and the circumstances which can lead to oral myiasis include persistent mouth opening together with poor hygiene. Such infestations have been reported mainly in developing countries such as in Asia. Although rare, nosocomial myiasis must be noted carefully, especially in case of hospitalized patients. This report describes three cases of nosocomial oral myiasis in hospitalized patients in ICU (intensive care unit in Tabriz, North West of Iran.

To examine the effect of heterogeneous case mix for a benchmarking analysis and interhospital comparison of the prevalence rates of nosocomial infection. Cross-sectional survey. Eleven hospitals located in Cyprus and in the region of Crete in Greece. The survey included all inpatients in the medical, surgical, pediatric, and gynecology-obstetrics wards, as well as those in intensive care units. Centers for Disease Control and Prevention criteria were used to define nosocomial infection. The information collected for all patients included demographic characteristics, primary admission diagnosis, Karnofsky functional status index, Charlson comorbidity index, McCabe-Jackson severity of illness classification, use of antibiotics, and prior exposures to medical and surgical risk factors. Outcome data were also recorded for all patients. Case mix-adjusted rates were calculated by using a multivariate logistic regression model for nosocomial infection risk and an indirect standardization method.Results. The overall prevalence rate of nosocomial infection was 7.0% (95% confidence interval, 5.9%-8.3%) among 1,832 screened patients. Significant variation in nosocomial infection rates was observed across hospitals (range, 2.2%-9.6%). Logistic regression analysis indicated that the mean predicted risk of nosocomial infection across hospitals ranged from 3.7% to 10.3%, suggesting considerable variation in patient risk. Case mix-adjusted rates ranged from 2.6% to 12.4%, and the relative ranking of hospitals was affected by case-mix adjustment in 8 cases (72.8%). Nosocomial infection was significantly and independently associated with mortality (adjusted odds ratio, 3.6 [95% confidence interval, 2.1-6.1]). The first attempt to rank the risk of nosocomial infection in these regions demonstrated the importance of accounting for heterogeneous case mix before attempting interhospital comparisons.

Full Text Available Uno de los problemas que actualmente se está presentando en el ámbito hospitalario, especialmente en las Unidades de Cuidados Intensivos (UCI es la neumonía nosocomial, entendida como una infección aguda del tracto respiratorio bajo, que aparece en los enfermos que ingresan al hospital. Una de las causas de estas infecciones es atribuida a conductas inadecuadas que realiza el personal de salud al atender pacientes infectados sin los elementos adecuados. Estudios epidemiológicos realizados en las UCI indican que uno de los principales mecanismos de transmisión de los agentes patógenos es el contacto, ya sea a través de las manos o de gotitas que se forman en el aire al comunicarse, por estornudo o por la tos; otro mecanismo es a través del aire, el cual tiene especial importancia en la contaminación de elementos y aparatos de uso exclusivo para pacientes. En los programas de prevención de infecciones nosocomiales se hace necesaria la intervención del psicólogo especializado en salud, cuyo objetivo primordial es la promoción de conductas tendientes a disminuir el riesgo de infección intrahospitalaria, por medio de la modificación comportamental de los profesionales de la salud y del paciente mismo.

The distribution of epidemiological markers (serotyping and phage-typing) of Serratia marcescens isolates from nosocomial episodes (63 nosocomial cutbreaks with 475 isolates, and 1208 sporadic cases) received in our laboratory during the period 1981-1991 was studied. The records for 1683 isolates from Spanish hospitals have been analyzed. In relation with the sporadic cases, the predominant types were serotype O6 (13.4%) and serotype O14 (11.4%); polyagglutinable strains accounted for 15.6%; in outbreaks, type O14 is clearly predominant (27.4%). Phage-typing was a good secondary marker, with a 87.9% of typability; the number of lytic patterns was very high, extended patterns (six or more phages) being the most frequent. We have studied the characteristics of S. marcescens isolates causing infections in the nosocomial environment in Spain.

Nosocomial and ventilator associated pneumonias that plague critically ill, elderly and long-term care residents could be reduced with effective oral hygiene practices facilitated collaboratively between nurses and dental hygienists. Nosocomial pneumonias, specifically aspiration pneumonias and ventilator-associated pneumonias in the elderly and infirm have become a major health care issue, The provision of oral care in hospital and hospital-like facilities presents challenges that can prevent patients from receiving optimal oral care One sequela can be aspiration pneumonia which ranks first in mortality and second in morbidity among all nosocomial infections. Since aspiration pneumonia is linked to the colonization of oral bacteria in dental plaque and biofilm, it is time to look for creative solutions to integrating the expertise of dental hygienists into health care teams in these institutional settings. A comprehensive review of the literature was conducted regarding the etiology and prevalence of health care related pneumonias. Evidence describing the challenges and barriers that the nurses, nursing staff, and dental hygienists face in the provision of oral care in hospitals and long-term care facilities is provided. Intercollaborative solutions to providing optimal oral care in hospitals and long-term care facilities are suggested. Dental hygienists have the expertise and practice experience to provide oral care in hospitals, long-term care and residential facilities. They can contribute to solving oral care challenges through intercollaboration with other health care team members. Yet, there are long-standing systemic barriers that must be addressed in order to provide this optimal care. Dental hygienists becoming better assimilated within the total health care team in hospital and residential facilities can positively impact the suffering, morbidity and mortality associated with aspiration pneumonias.

In this study we describe the changes in medical practices and nosocomial infection rates in obstetrics observed through a surveillance network in the South East of France. The maternity units which belong to this network participated in voluntary surveillance using the network's methodology. The criteria for the diagnosis of nosocomial infections were in accordance with the methods described by the Centers for Disease Control and Prevention. 101240 pregnancies including 18503 caesareans (18.3%) were included in the network from 1997 to 2000. During the study period, nosocomial infection rates following caesarean section and vaginal delivery decreased respectively from 7.8% to 4.3% (p infection control programs in maternity units has been confirmed by the results of this surveillance network. During the study period, both obstetrics-related risk factors for nosocomial infection and observed hospital-acquired infection rates were dramatically reduced, what prove an improvement of quality of care in maternity units.

To determine the pattern of nosocomial infections in two ICUs' of a teaching hospital in terms of frequency, common sites of infection, the pathogens involved and the antibiotic sensitivity patterns. It was conducted in two medical ICUs (Neurology and Nephrology) of a public tertiary care hospital. Data was collected prospectively on patients suspected to have developed nosocomial infection after 48 hours of admission to the ICU according to objective. There were 101 cases of suspected nosocomial infection out of a total of 254 patients. The frequency of nosocomial infection was 39.7%. UTI developed in 44.6%, while 27% had blood stream infection, and 21% had pneumonia. Each of the three major sites of infection was strongly associated with the use of invasive devices. Escherichia (E.) coli was the most common organism isolated followed by Pseudomonas aeruginosa and Klebsiella. E. coli and Klebsiella showed a maximum sensitivity to Imipenem followed by Tazocin (pipericillin + tazobactam). Pseudomonas aeruginosa was sensitive to Amikacin and Fosfomycin. The high frequency of nosocomial infection suggests that more strict measures regarding invasive devices should be taken in future to control the infection and limit the emergence of antibiotic resistant organisms.

Kampf, Günter; Löffler, Harald; Gastmeier, Petra

2009-10-01

The WHO regards hand hygiene as an essential tool for the prevention of nosocomial infection, but compliance in clinical practice is often low. The relevant scientific literature and national and international evidence-based recommendations (Robert Koch Institute [Germany], WHO) were evaluated. Hygienic hand disinfection has better antimicrobial efficacy than hand-washing and is the procedure of choice to be performed before and after manual contact with patients. The hands should be washed, rather than disinfected, only when they are visibly soiled. Skin irritation is quite common among healthcare workers and is mainly caused by water, soap, and prolonged wearing of gloves. Compliance can be improved by training, by placing hand-rub dispensers at the sites where they are needed, and by physicians setting a good example for others. Improved compliance in hand hygiene, with proper use of alcohol-based hand rubs, can reduce the nosocomial infection rate by as much as 40%.

Nosocomial infections are the main adverse events during health care delivery. Hand hygiene is the fundamental strategy for the prevention of nosocomial infections. Microbial characteristics of nosocomial infections in the Asia-Pacific region have not been investigated fully. Correlation between the use of hand hygiene products and the incidence of nosocomial infections is still unknown. This study investigates the microbial characteristics of nosocomial infections in the Asia-Pacific region and analyzes the association between the utilization of hand hygiene products and the incidence of nosocomial infections. A total of 78,344 patients were recruited from a major tertiary hospital in China. Microbial characteristics of major types of nosocomial infections were described. The association between the utilization of hand hygiene products and the incidence of nosocomial infections was analyzed using correlation and regression models. The overall incidence of nosocomial infections was 3.04%, in which the incidence of surgical site infection was 1%. Multi-drug resistance was found in 22.8% of all pathogens, in which multi-drug-resistant Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus were 56.6% and 54.9%, respectively. The utilization of hand hygiene products (including hand sanitizer, soap and paper towel) was associated negatively with the incidence of surgical site infection in surgical departments and the incidence of nosocomial infections in non-intensive care unit (ICU) departments (especially in surgical departments). Regression analysis further identified that higher utilization of hand hygiene products correlated with decreased incidence of major types of nosocomial infections. Multi-drug-resistant organisms are emerging in Asia-Pacific health care facilities. Utilization of hand hygiene products is associated with the incidence of nosocomial infections.

To investigate the role of donor human milk in the prevention of nosocomial infection in very low birth weight infants. MeETHODS: A total of 105 hospitalized preterm infants with a very low birth weight were enrolled. They were classified into mother's own milk feeding group, donor human milk feeding group, and preterm formula feeding group, with 35 infants in each group. The three groups were compared in terms of incidence rates of nosocomial infection, necrotizing enterocolitis, and feeding intolerance, time to full enteral feeding, and early growth indices. Compared with the preterm formula feeding group, the donor human milk feeding group and the mother's own milk feeding group had significantly lower incidence rates of nosocomial infection and necrotizing enterocolitis and shorter time to full enteral feeding (Pmilk can be used in case of a lack of mother's own milk and may help to reduce nosocomial infection.

Patients admitted during a 6-month period to a maternity hospital in Saudi Arabia were studied for nosocomial infections and misuse of antibiotics. Patient history and diagnosis on admission and subsequent clinical and laboratory data were analysed. Infection developing from 72 h after admission was considered nosocomial. Therapeutic and prophylactic data as recorded on the patients' charts were assessed for possible misuse of antibiotics. Of 3439 patients, 136 (4.0%) developed nosocomial infection: 2.0%, 8.9% and 37.7% in obstetric, gynaecologic and nursery patients, respectively. Infections among adults were mostly found in the urinary (44.4%) and lower genital (33.3%) tracts. Among newborns, over 70% of cases were eye and ear (29.8%), skin (26.2%) and blood (19.0%) infections. Gram-negative bacteria caused 65.7% of the infections. Over 90% of the bacterial isolates were multidrug-resistant. About 24% of patients received single or multiple antibiotics; 57.2% were misused. The minimal hospital cost estimate for both nosocomial infections and misused antibiotics was US $318,705. The findings of this study, the first of its type in this region, should prompt improved infection control measures as well as educational and antibiotic restriction interventions.

Full Text Available OBJETIVO:Rever a literatura atual que aborda o crescimento e o desenvolvimento cerebral de crianças prematuras e as alterações cognitivas e motoras que podem decorrer da prematuridade. FONTES DE DADOS: Foram utilizadas as bases de dados Medline e Lilacs, selecionados artigos publicados entre os anos de 2000 e 2007 e livros-texto com conteúdo relevante. SÍNTESE DOS DADOS: A evolução do recém-nascido pré-termo diferencia-se da evolução apresentada pela população a termo. Estudos têm demonstrado que ex-prematuros apresentam alterações anatômicas cerebrais que se associam a prejuízos cognitivos. Várias regiões do sistema nervoso central (substância cinzenta, substância branca, corpo caloso, núcleo caudado, hipocampo e cerebelo têm seus volumes avaliados por neuroimagem e, apesar de resultados controversos, parecem ter desenvolvimento alterado nessa população. Diante disso, espera-se haver repercussão funcional e/ou cognitiva em crianças, adolescentes e adultos nascidos prematuramente. Ex-prematuros avaliados na infância tardia e na adolescência demonstram alterações de quociente de inteligência, memória, capacidade para cálculos e função cognitiva global. Déficits motores, na capacidade de planejamento e de associação, na coordenação motora e na atenção também foram relatados na literatura. CONCLUSÕES: A prematuridade pode levar a alterações anatômicas e estruturais do cérebro devido à interrupção das etapas de desenvolvimento pré-natal. Tais alterações podem causar déficits funcionais, tornando os ex-prematuros sujeitos a problemas cognitivos e motores, assim como suas repercussões nas atividades de vida diária, mesmo na adolescência e idade adulta.OBJECTIVE:To review the current literature about brain growth and development of premature children, as well as the motor and cognitive changes that may result from prematurity.

We describe an outbreak of nosocomial endophthalmitis due to a common source, which was determined to be trypan blue solution prepared in the hospital's pharmacy service. We assume that viable bacteria probably gained access to the trypan blue stock solution during cooling after autoclaving. The temporal cluster of Pseudomonas aeruginosa endophthalmitis was readily perceived on the basis of clinical and microbiological findings, and an exogenous source of contamination was unequivocally identified by means of DNA fingerprinting.

Nosocomially-acquired Pseudomonas aeruginosa remains a serious cause of infection and septic mortality in burn patients. This study was conducted to quantify the impact of nosocomially-transmitted resistant P. aeruginosa in a burn population. Using a TRACS burn database, 48 patients with P. aeruginosa resistant to gentamicin were identified (Pseudomonas group). Thirty-nine were case-matched to controls without resistant P. aeruginosa cultures (control group) for age, total body surface area, admission year, and presence of inhalation injury. Mortality and various morbidity endpoints were examined, as well as antibiotic costs. There was a significantly higher mortality rate in the Pseudomonas group (33% vs. 8%, p products used (packed cells 51.1 +/- 8.0 vs. 21.1 +/- 3.4, p < 0.01; platelets 11.9 +/- 3.0 vs. 1.4 +/- 0.7, p < 0.01) were all significantly higher in the Pseudomonas group. Cost of antibiotics was also significantly higher ($2,658.52 +/- $647.93 vs. $829.22 +/- $152.82, p < 0.01). Nosocomial colonization or infection, or both, of burn patients with aminoglycoside-resistant P. aeruginosa is associated with significantly higher morbidity, mortality, and cost of care. Increased resource consumption did not prevent significantly higher mortality rates when compared with that of control patients. Thus, prevention, identification, and eradication of nosocomial Pseudomonas contamination are critical for cost-effective, successful burn care.

Full Text Available Introduction. A basic element in preventing and combating nosocomial infections is the medical personnel knowledge. It is up to health care workers to determine whether the hospital environment will be safe for both patients and those employed in this sector. The aim of the study was to present the level of nursing staff knowledge of nosocomial infections. Materials and methods. The research was carried out in the Podkarpackie Center of Cardiovascular Interventions in Sanok. The study group consisted of all nurses working in the Hemodynamic Department - 20 people. The tests were carried out using the diagnostic survey method. The research tool was the author's questionnaire. Results. The nurses were aware that the scale of the problem of nosocomial infections was important. Almost all nurses rated their level of knowledge of hospital-acquired infections very well. However, the full definition of the term "nosocomial infections" was not given by about a quarter of respondents. In hospitals nurses did not always follow the rules of aseptic and antiseptic treatment. In addition, they did not see the need to educate patients and their families about the prevention of infections. Conclusions. Hospitals should carry out monitoring of nurses’ compliance with the procedures that are aimed at the elimination of ward infections and should consistently strive at their best to apply these procedures at their workplace. The ward staff should be involved in the education of patients and their families in the prevention of nosocomial infections.

Nosocomial outbreak of hepatitis B virus infection involving two hospitals in the Republic of Ireland.

The routes of nosocomial hepatitis B virus (HBV) transmission have changed over the years. Initiatives to prevent transfusion-associated HBV and healthcare worker-to-patient transmission have had a positive impact on these transmission routes. Recent reports of outbreaks of nosocomial HBV have implicated breaches in standard precautions as important causes of HBV transmission. This report describes a nosocomial outbreak of HBV infection in the Republic of Ireland, which occurred between January 2005 and March 2006. The outbreak was detected following identification of a case of acute HBV infection in a patient whose only risk factor was a recent surgical procedure. The extensive multi-agency investigation that followed revealed that the patient was one of five cases of acute HBV infection and that four separate transmission events between infectious cases had occurred in two different hospitals over a 15-month period. A definitive cause for each transmission event was not identified, although lapses in adherence to standard precautions, safe injection and phlebotomy practices could not be ruled out. Two secondary cases of acute HBV infection in community contacts of two of the nosocomial cases were identified. Phylogenetic analysis proved a useful tool in confirming infection with a pre-core HBV mutant and viral transmission between the seven patients. A patient notification exercise involving 1028 potentially exposed patients found no evidence of additional cases of nosocomial HBV infection. These findings highlight the importance of consistent application of standard precautions.

Nosocomial infection remains an important health problem in long stay (>3 days) pediatric intensive care unit (PICU) patients. Admission risk factors related to the development of nosocomial infection in long stay immune competent patients in particular are not known. Post-hoc analysis of the previously published Critical Illness Stress induced Immune Suppression (CRISIS) prevention trial database, to identify baseline risk factors for nosocomial infection. Because there was no difference between treatment arms of that study in nosocomial infection in the population without known baseline immunocompromise, both arms were combined and the cohort that developed nosocomial infection was compared with the cohort that did not. There were 254 long stay PICU patients without known baseline immunocompromise. Ninety (35%) developed nosocomial infection, and 164 (65%) did not. Admission characteristics associated with increased nosocomial infection risk were increased age, higher Pediatric Risk of Mortality version III score, the diagnoses of trauma or cardiac arrest and lymphopenia (P risk of developing nosocomial infection (P risk factors (P < 0.05); whereas trauma tended to be related to nosocomial infection development (P = 0.07). These data suggest that increasing age, cardiac arrest and lymphopenia predispose long stay PICU patients without known baseline immunocompromise to nosocomial infection. These findings may inform pre-hoc stratification randomization strategies for prospective studies designed to prevent nosocomial infection in this population.

Severity or mortality prediction of nosocomial pneumonia could aid in the effective triage of patients and assisting physicians. To compare various severity assessment scoring systems for predicting intensive care unit (ICU) mortality in nosocomial pneumonia patients. A prospective cohort study was conducted in a tertiary care university-affiliated hospital in Manipal, India. One hundred patients with nosocomial pneumonia, admitted in the ICUs who developed pneumonia after >48h of admission, were included. The Nosocomial Pneumonia Mortality Prediction (NPMP) model, developed in our hospital, was compared with Acute Physiology and Chronic Health Evaluation II (APACHE II), Mortality Probability Model II (MPM 72  II), Simplified Acute Physiology Score II (SAPS II), Multiple Organ Dysfunction Score (MODS), Sequential Organ Failure Assessment (SOFA), Clinical Pulmonary Infection Score (CPIS), Ventilator-Associated Pneumonia Predisposition, Insult, Response, Organ dysfunction (VAP-PIRO). Data and clinical variables were collected on the day of pneumonia diagnosis. The outcome for the study was ICU mortality. The sensitivity and specificity of the various scoring systems was analysed by plotting receiver operating characteristic (ROC) curves and computing the area under the curve for each of the mortality predicting tools. NPMP, APACHE II, SAPS II, MPM 72  II, SOFA, and VAP-PIRO were found to have similar and acceptable discrimination power as assessed by the area under the ROC curve. The AUC values for the above scores ranged from 0.735 to 0.762. CPIS and MODS showed least discrimination. NPMP is a specific tool to predict mortality in nosocomial pneumonia and is comparable to other standard scores. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd.

Hand hygiene is a fundamental measure for the control of nosocomial infection. However, sustained compliance with hand hygiene in health care workers is poor. We attempted to enhance compliance with hand hygiene by implementing education, training, and performance feedback. We measured nosocomial infections in parallel. We monitored the overall compliance with hand hygiene during routine patient care in intensive care units (ICUs); 1 medical surgical ICU and 1 coronary ICU, of 1 hospital in Buenos Aires, Argentina, before and during implementation of a hand hygiene education, training, and performance feedback program. Observational surveys were done twice a week from September 2000 to May 2002. Nosocomial infections in the ICUs were identified using the National Nosocomial Infections Surveillance (NNIS) criteria, with prospective surveillance. We observed 4347 opportunities for hand hygiene in both ICUs. Compliance improved progressively (handwashing adherence, 23.1% (268/1160) to 64.5% (2056/3187) (RR, 2.79; 95% CI: 2.46-3.17; P nosocomial infection in both ICUs decreased from 47.55 per 1000 patient-days (104/2187) to 27.93 per 1000 patient days (207/7409) RR, 0.59; 95% CI: 0.46-0.74, P hand hygiene, coinciding with a reduction in nosocomial infection rates in the ICUs.

During 5 1/2 years all infections arising in the hospital (nosocomial infections) were registered prospectively by an infection control nurse. The incidence of all nosocomial infections in 3192 maternity patients was 2.1%. In 10,569 women following vaginal deliveries 2.6% and in 1,353 women following Caesarean section 21.1%. The commonest infections were urinary tract infections, endometritis, infections of the abdominal wound or the episiotomy, and a phlebitis of the intravenous infusion site. Measures to prevent infection resulted in a steadily decreasing incidence of infections during the 6 years of registration of nosocomial infections.

Nosocomial infections generate high morbidity and mortality in children undergoing cardiac surgery. To determine risk factors for nosocomial infections in children after congenital heart surgery. A retrospective case-control study, in patients younger than 15 years undergoing surgery for congenital heart disease from January 2007 to December 2011 admitted to the Pediatric Critical Patient Unit (UPC-P) in a university hospital. For cases, the information was analyzed from the first episode of infection. 39 patients who develop infections and 39 controls who did not develop infection were enrolled. The median age of cases was 2 months. We identified a number of factors associated with the occurrence of infections, highlighting in univariate analysis: age, weight, univentricular heart physiology, complexity of the surgical procedure according to RACHS-1 and cardiopulmonary bypass (CPB) time ≥ 200 minutes. Multivariate analysis identified CPB time ≥ 200 minutes as the major risk factor, with an OR of 11.57 (CI: 1.04 to 128.5). CPB time ≥ 200 minutes was the mayor risk factor associated with the development of nosocomial infections.

Acinetobacter spp. has emerged as nosocomial pathogen during the past few decades in hospitals all over the world, but it has increasingly been implicated as a serious nosocomial pathogen in military hospitals. The aim of this study was to analyse and compare the surveillance data on Acinetobacter nosocomial colonization/infection (NCI) collected during the wartime with the data collected in peacetime. We conducted a prospective study of incidence of Acinetobacter spp. colonization/infection. Also, the two nested case-control studies were conducted. The patients with nosocomial infection (cases) were compared with those with nosocomial colonization (controls) during the two different periods, wartime and peacetime. The patients with NCI by Acinetobacter spp. were identified by the case-based surveillance. The surveillance covered all the patients in 6 surgical clinics. During the study periods a total of 166 patients had cultures that grew Acinetobacter spp. and the pooled rates of Acinetobacter spp. colonization and infection were significantly higher in wartime. When patients with NCI in wartime were compared with those with NCI in peacetime significant differences were observed. In the war year, the patients were more significantly males (p war and peace period.

A NOSOCOMIAL INFECTION MANIFESTED AS ERYSIPELAS IN PEMPHIGUS FOLIACEUS PATIENT UNDER INTRAVENOUS DEXAMETHASONE TREATMENT

Directory of Open Access Journals (Sweden)

Achmad Yudha Pranata

2016-05-01

Full Text Available Introduction: Puncture wound in diagnostic interventions permits the entry of bacteria into the skin or soft tissue, thus precipitating nosocomial infection, such as erysipelas. There are other risk factors of nosocomial infections including old age, immunosuppressive drugs, and underlying diseases. Pemphigus foliaceus (PF is an autoimmune disease with corticosteroid treatment as the mainstay therapy, which could cause immunosuppression and predispose patients to infection. The objective of this paper was to report erysipelas as one of the manifestations of nosocomial infection in patients under immunosuppressive therapy. Case: A case of erysipelas acquired on the 9th day of hospitalization in a PF patient underwent intravenous dexamethasone injection, with history of puncture wounds on the previous day on the site of erysipelas was reported. The clinical findings of erysipelas were well defined, painful erythema and edema that felt firm and warm on palpation, with blisters and pustules on top. Gram staining from the pustules and blisters fluid revealed Gram (+ cocci. Patient was given 2 grams intravenous ceftriaxone for 7 days and saline wet compress. Improvement on the erysipelas was seen the day after ceftriaxone injection. The patient was discharged after 12 days of hospitalization with improvement both on the PF and the erysipelas. On the next visit 7 days later, the erysipelas lesion disappeared. Conclusion: Puncture wound and immunosuppresive treatment are the factors that could cause erysipelas as a nosocomial infection, and an appropriate treatment of the infection would decrease the functional disability of the patient.

Nosocomial pneumonia is the most important infectious complication in patients admitted to intensive care units. Kinetic bed therapy may reduce the incidence of nosocomial pneumonia in mechanically ventilated patients. The objective of this study was to investigate whether kinetic bed therapy reduces the incidence of nosocomial pneumonia and improves outcomes in critically ill mechanically ventilated patients. We searched Medline, EMBASE, CINAHL, CENTRAL, and AMED for studies, as well as reviewed abstracts of conference proceedings, bibliographies of included studies and review articles and contacted the manufacturers of medical beds. Studies included were randomized or pseudo-randomized clinical trials of kinetic bed therapy compared to standard manual turning in critically ill mechanically ventilated adult patients. Two reviewers independently applied the study selection criteria and extracted data regarding study validity, type of bed used, intensity of kinetic therapy, and population under investigation. Outcomes assessed included the incidence of nosocomial pneumonia, mortality, duration of ventilation, and intensive care unit and hospital length of stay. Fifteen prospective clinical trials were identified, which included a total of 1,169 participants. No trial met all the validity criteria. There was a significant reduction in the incidence of nosocomial pneumonia (pooled odds ratio (OR) 0.38, 95% confidence interval (CI) 0.28 to 0.53), but no reduction in mortality (pooled OR 0.96, 95%CI 0.66 to 1.14), duration of mechanical ventilation (pooled standardized mean difference (SMD) -0.14 days, 95%CI, -0.29 to 0.02), duration of intensive care unit stay (pooled SMD -0.064 days, 95% CI, -0.21 to 0.086) or duration of hospital stay (pooled SMD 0.05 days, 95% CI -0.18 to 0.27). While kinetic bed therapy has been purported to reduce the incidence of nosocomial pneumonia in mechanically ventilated patients, the overall body of evidence is insufficient to support this

Full Text Available This research was conducted for estimating the knowledge and prevention of nosocomial infection among ward nurses at Federal Medical Centre (FMC, Umuahia Abia state. Four objectives were set, and four questions were formulated. A descriptive survey research method was used for the study. A sample size of one hundred and fifty (150 nurses was drawn from eight wards (medical and surgical, at FMC, Umuahia. A self-developed questionnaire with seventeen (17 structured questions was the instrument of data collection. Data were collected, analyzed, and presented in tables, pie chart, bar chart, histogram, and percentages. The results revealed that the nurses were well knowledgeable about nosocomial infection, although little deficiencies existed in the area of infection control practice and compliance, such as hand washing frequency. This study therefore recommends continuing education/seminar/workshop for all health care givers, to sensitize them with the knowledge and practice of nosocomial infection.

Full Text Available This retrospective study examined the incidence and factors influencing the occurrence of nonsocomial pneumonia (NP in a neuromedical intensive care unit (NICU. Of the 57 patients admitted to the NICU over one year, 26% developed nosocomial pneumonia. It was observed that the infected patients were significantly older than the noninfected (43+15 vs 22+18 years; p<0.001, had a longer NICU stay (33+31 vs 18+18 days: p=0.05 and needed longer duration of mechanical ventilation (20+25 vs 9 + 12 days: P<0.05. Patients with neuromuscular diseases had a trend towards higher incidence of NP than those with encephalopathy and therapeutic interventions such as plasmapheresis, blood transfusion and inotropic therapy did not influence the incidence of nosocomial pneumonia. The NICU mortality was not significantly influenced by nosocomial pneumonia. Pseudomonas aerugenosa was the predominant organism responsible for pneumonia. Nine percent of the tracheobronchial isolates were resistant to the routinely-tested antibiotics. In conclusion, nosocornial pneumonia is a common complication in a NICU and while it increases the duration of NICU stay, mortality appears to be uninfluenced.

Full Text Available Abstract Background This study aimed to determine the occurrence of nosocomial infections (NIs, including infection rates, main infection sites, and common microorganisms. Patients included in the study were taken from a newborn intensive care unit (NICU, in a hospital in South Korea. Methods A retrospective cohort study was performed by reviewing chart. The subjects were 489 neonates who were admitted to the NICU, survived longer than 72 hours, and not transferred to another unit, between Jan. 1. 1995 to Sep. 30, 1999. NIs were identified according to the NNIS definition. Data were analyzed with descriptive statistics. Results Cumulative incidence rate for NIs was 30.3 neonates out of 100 admissions, with a total of 44.6 infections. The incidence density was average 10.2 neonates and 15.1 infections per 1000 patient days. The most common infections were pneumonia (28%, bloodstream infection (26%, and conjunctivitis (22%. Major pathogens were Gram-positives such as Staphylococcus aureus and coagulase-negative staphylococci. The factors associated with NI was less than 1500 g of birth weight, less than 32 weeks of gestational age, and less than 8 of apgar score. There's no statistical difference in discharge status between two groups, but hospital stay was longer in subjects with nosocomial infection than those without infection. Conclusion Although the distribution of pathogens was similar to previous reports, a high rate of nosocomial infection and in particular conjunctivitis was observed in this study that merits further evaluation.

We aimed to assess the hospital economic costs of nosocomial multi-drug resistant Pseudomonas aeruginosa acquisition. A retrospective study of all hospital admissions between January 1, 2005, and December 31, 2006 was carried out in a 420-bed, urban, tertiary-care teaching hospital in Barcelona (Spain). All patients with a first positive clinical culture for P. aeruginosa more than 48 h after admission were included. Patient and hospitalization characteristics were collected from hospital and microbiology laboratory computerized records. According to antibiotic susceptibility, isolates were classified as non-resistant, resistant and multi-drug resistant. Cost estimation was based on a full-costing cost accounting system and on the criteria of clinical Activity-Based Costing methods. Multivariate analyses were performed using generalized linear models of log-transformed costs. Cost estimations were available for 402 nosocomial incident P. aeruginosa positive cultures. Their distribution by antibiotic susceptibility pattern was 37.1% non-resistant, 29.6% resistant and 33.3% multi-drug resistant. The total mean economic cost per admission of patients with multi-drug resistant P. aeruginosa strains was higher than that for non-resistant strains (15,265 vs. 4,933 Euros). In multivariate analysis, resistant and multi-drug resistant strains were independently predictive of an increased hospital total cost in compared with non-resistant strains (the incremental increase in total hospital cost was more than 1.37-fold and 1.77-fold that for non-resistant strains, respectively). P. aeruginosa multi-drug resistance independently predicted higher hospital costs with a more than 70% increase per admission compared with non-resistant strains. Prevention of the nosocomial emergence and spread of antimicrobial resistant microorganisms is essential to limit the strong economic impact.

Phase I was electronic monitoring and direct observation; phase II was electronic monitoring and computerized voice prompts for failure to perform hand hygiene on room exit; and phase III was electronic monitoring only. Nine-room, 14-bed intermediate care unit in a university, tertiary-care institution. All patient rooms, utility room, and staff lavatory were monitored electronically. All healthcare personnel including physicians, nurses, nursing support personnel, ancillary staff, all visitors and family members, and any other personnel interacting with patients on the intermediate care unit. All patients with an intermediate care unit length of stay >48 hrs were followed for nosocomial infection. Electronic monitoring during all phases, computerized voice prompts during phase II only. We evaluated a total of 283,488 electronically monitored entries into a patient room with 251,526 exits for 420 days (10,080 hrs and 3,549 patient days). Compared with phase I, hand hygiene compliance in patient rooms improved 37% during phase II (odds ratio, 1.38; 95% confidence interval, 1.04-1.83) and 41% in phase III (odds ratio, 1.41; 95% confidence interval, 1.07-1.84). When adjusting for patient admissions during each phase, point estimates of nosocomial infections decreased by 22% during phase II and 48% during phase III; when adjusting for patient days, the number of infections decreased by 10% during phase II and 40% during phase III. Although the overall rate of nosocomial infections significantly decreased when combining phases II and III, the association between nosocomial infection and individual phase was not significant. Electronic monitoring provided effective ongoing feedback about hand hygiene compliance. During both the voice prompt phase and post

Patients undergoing extracorporeal membrane oxygenation (ECMO) are at increased risk of infection. We present the first known report of nosocomial infection with Cupriavidus pauculus attributable to contamination from ECMO equipment and describe the measures taken to halt subsequent infections. A cluster of infections in ECMO patients should prompt team members to consider contamination of equipment with environmental pathogens as a possible cause.

Full Text Available Se informa que la neumonía asociada a ventilación mecánica es un tipo particular de infección nosocomial frecuente en los pacientes críticos y se asocia con altas tasas de morbilidad y mortalidad. Su origen es polimicrobiano y depende de múltiples factores de riesgo como: edad, días de ventilación, poca movilización, alcalinización gástrica, trauma, coma y uso de medicamentos como: sedantes y bloqueadores, entre otros. Las estrategias fundamentales para la prevención de esta entidad, tienen como objetivo reducir el impacto de los factores de riesgo ya sean intrínsecos o extrínsecos. Su pronóstico depende del momento de aparición de los síntomas, por lo que se clasifica de inicio temprano, aquella que aparece antes de los 4 días de ventilación, producida por los gérmenes de la orofaringe, se asocia a baja mortalidad y generalmente es de buen pronóstico y la de inicio tardío que aparece después de los 5 días de apoyo ventilatorio, producida por cepas multirresistentes y de muy mal pronóstico. El diagnóstico es difícil por los múltiples criterios propuestos a través de los diferentes estudios realizados. Los emitidos por la Sociedad Americana del Tórax en 1999 son más específicos, pues reúnen las condiciones clínicas, microbiológicas y no microbiológicas, las cuales no son invasivas, resultan fáciles y rápidas de recoger y pueden aplicarse a cualquier grupo de edad, independientemente de la causa que provocó la enfermedad. El análisis microscópico directo y el conocimiento del mapa epidemiológico de cada servicio, permiten el inicio de un tratamiento empírico más efectivo. Aunque la tendencia actual en el tratamiento es la monoterapia, no existe un antibiótico ideal que cubra la totalidad del espectro de los microorganismos responsables de esta entidad.It is reported that pneumonia associated with mechanical ventilation is a particular type of nosocomial infection that is frequently found among critical

Ever since Crimean-Congo hemorrhagic fever [CCHF] discovered in India, several outbreaks of this disease have been recorded in Gujarat State, India. During the year 2011 to 2015 several districts of Gujarat and Rajasthan state (Sirohi) found to be affected with CCHF including the positivity among ticks and livestock. During these years many infected individuals succumbed to this disease; which subsequently led to nosocomial infections. Herein, we report CCHF cases recorded from Rajasthan state during January 2015. This has affected four individuals apparently associated with one suspected CCHF case admitted in a private hospital in Jodhpur, Rajasthan. A 30-year-old male was hospitalized in a private hospital in Jodhpur, Rajasthan State, who subsequently had developed thrombocytopenia and showed hemorrhagic manifestations and died in the hospital. Later on, four nursing staff from the same hospital also developed the similar symptoms (Index case and Case A, B, C). Index case succumbed to the disease in the hospital at Jodhpur followed by the death of the case A that was shifted to AIIMS hospital, Delhi due to clinical deterioration. Blood samples of the index case and Case A, B, C were referred to the National institute of Virology, Pune, India for CCHF diagnosis from the different hospitals in Rajasthan, Delhi and Gujarat. However, a sample of deceased suspected CCHF case was not referred. Subsequently, blood samples of 5 nursing staff and 37 contacts (Case D was one of them) from Pokhran area, Jaisalmer district were referred to NIV, Pune. It clearly indicated that nursing staff acquired a nosocomial infection while attending the suspected CCHF case in an Intensive Care Unit of a private hospital in Jodhpur. However, one case was confirmed from the Pokhran area where the suspected CCHF case was residing. This case might have got the infection from suspected CCHF case or through other routes. CCHF strain associated with these nosocomial infections shares the

Neonatal nosocomial infections are public health threats in the developing world, and successful interventions are rarely reported. A before-and-after study was conducted in the neonatal unit of the Hôpital Principal de Dakar, Senegal to assess the efficacy of a multi-faceted hospital infection control programme implemented from March to May 2005. The interventions included clustering of nursing care, a simple algorithm for empirical therapy of suspected early-onset sepsis, minimal invasive care and promotion of early discharge of neonates. Data on nosocomial bloodstream infections, mortality, bacterial resistance and antibiotic use were collected before and after implementation of the infection control programme. One hundred and twenty-five infants were admitted immediately before the programme (Period 1, January-February 2005) and 148 infants were admitted immediately after the programme (Period 2, June-July 2005). The two groups of infants were comparable in terms of reason for admission and birth weight. After implementation of the infection control programme, the overall rate of nosocomial bloodstream infections decreased from 8.8% to 2.0% (P=0.01), and the rate of nosocomial bloodstream infections/patient-day decreased from 10.9 to 2.9/1000 patient-days (P=0.03). Overall mortality rates did not differ significantly. The proportion of neonates who received antimicrobial therapy for suspected early-onset sepsis decreased significantly from 100% to 51% of at-risk infants (Punit, simple, low-cost and sustainable interventions led to the control of a high incidence of bacterial nosocomial bloodstream infections, and the efficacy of these interventions was long-lasting. Such interventions could be extended to other low-income countries. Copyright © 2011 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

Nosocomial infection control in healthcare settings: Protection against emerging infectious diseases.

Science.gov (United States)

Fu, Chuanxi; Wang, Shengyong

2016-04-12

The Middle East respiratory syndrome (MERS) outbreak in Korea in 2015 may be attributable to poor nosocomial infection control procedures implemented. Strict infection control measures were taken in the hospital where an imported case with MERS was treated in southern China and 53 health care workers were confirmed to be MERS-CoV negative. Infection control in healthcare settings, in which patients with emerging infectious diseases such as MERS, Ebola virus disease, and the severe acute respiratory syndrome (SARS) are diagnosed and treated, are often imperfect. When it comes to emerging or unknown infectious diseases, before the imported case was finally identified or community transmission was reported, cases have often occurred in clusters in healthcare settings. Nosocomial infection control measures should be further strengthened among the workers and inpatients in designated healthcare settings that accommodate suspected cases suffering from emerging or unknown infectious diseases.

To investigate the association between the use of proton pump inhibitors (PPI) and nosocomial pneumonia and gastrointestinal bleeding in bedridden patients receiving tube feeding. A total of 116 bedridden hospitalized patients receiving tube feeding, of which 80 were supported by percutaneous endoscopic gastrostomy and 36 by nasogastric tube, were included in the present study. The patients were divided into two groups: 62 patients treated with PPI (PPI group) and 54 patients without PPI (non-PPI group). Mortality due to nosocomial pneumonia was evaluated using the Kaplan-Meier approach and the log-rank test. A total of 36 patients (31%) died of nosocomial pneumonia during the observation period; the mortality rate due to nosocomial pneumonia was significantly higher in the PPI group than in the non-PPI group (P = 0.0395). Cox proportional hazard analysis showed that the use of PPI and lower levels of serum albumin were independent predictors of 2-year mortality due to nosocomial pneumonia. Gastrointestinal bleeding was observed in four patients in the non-PPI group (7.7%) and in one patient in the PPI group (1.6%); there was no significant difference between the two groups. The use of PPI in bedridden tube-fed patients was independently associated with mortality due to nosocomial pneumonia, and the PPI group had a non-significant lower incidence of gastrointestinal bleeding than the non-PPI group.

Full Text Available Abstract Introduction: Extracorporeal membrane oxygenation (ECMO has become a standard technique over the past few decades in intensive care unit (ICU. Objective: A review of pediatric patients who received ECMO support in the pediatric cardiac ICU was conducted to determine the incidence, risk factors and causal organisms related to acquired infections and assess the survival rates of ECMO patients with nosocomial infections. Methods: Sixty-six patients who received ECMO support in the pediatric cardiac ICU between January 2011 and June 2014 were included in the study. Demographic, echocardiographic, hemodynamic features and surgical procedures were reviewed. Results: Sixty-six patients received a total of 292.5 days of venoarterial ECMO support. Sixty were postoperative patients. Forty-five patients were weaned from ECMO support with an ECMO survival rate of 68.2%. The rate of infection was 116.2/1000 ECMO days. Prolonged ICU stay, duration of ventilation and ECMO were found associated with development of nosocomial infection and only the duration of ECMO was an independent risk factor for nosocomial infections in ECMO patients. Conclusion: The correction of the underlying process leading to ECMO support and shortening the length of ECMO duration together with stricter application of ECMO indications would improve the infection incidence and hospital surveillance of the patient group.

Full Text Available La prematuridad extrema constituye un riesgo importante para la función visual, no sólo por los efectos potencialmente devastadores para el ojo de la retinopatía del prematuro, que puede llegar a la ceguera, sino porque se asocia además al desarrollo de miopía, estrabismo y déficit visual cerebral. A medida que sobreviven cada día prematuros más extremos por la mejoría del cuidado neonatal, estas patologías derivadas de la prematuridad aumentan en prevalencia en la población infantil. Hoy en día, la retinopatía del prematuro es la primera causa de ceguera infantil en los países en desarrollo como el nuestro. Aquellos niños que no quedan ciegos por ella, pueden presentar las otras complicaciones quedando con algún grado de déficit visual. La ceguera, o incluso limitación visual de un niño genera muchos más años de discapacidad que una catarata, un glaucoma o una maculopatía, patologías que se presentan en general en los últimos años de vida.

Full Text Available Abstract Background We aimed to assess the hospital economic costs of nosocomial multi-drug resistant Pseudomonas aeruginosa acquisition. Methods A retrospective study of all hospital admissions between January 1, 2005, and December 31, 2006 was carried out in a 420-bed, urban, tertiary-care teaching hospital in Barcelona (Spain. All patients with a first positive clinical culture for P. aeruginosa more than 48 h after admission were included. Patient and hospitalization characteristics were collected from hospital and microbiology laboratory computerized records. According to antibiotic susceptibility, isolates were classified as non-resistant, resistant and multi-drug resistant. Cost estimation was based on a full-costing cost accounting system and on the criteria of clinical Activity-Based Costing methods. Multivariate analyses were performed using generalized linear models of log-transformed costs. Results Cost estimations were available for 402 nosocomial incident P. aeruginosa positive cultures. Their distribution by antibiotic susceptibility pattern was 37.1% non-resistant, 29.6% resistant and 33.3% multi-drug resistant. The total mean economic cost per admission of patients with multi-drug resistant P. aeruginosa strains was higher than that for non-resistant strains (15,265 vs. 4,933 Euros. In multivariate analysis, resistant and multi-drug resistant strains were independently predictive of an increased hospital total cost in compared with non-resistant strains (the incremental increase in total hospital cost was more than 1.37-fold and 1.77-fold that for non-resistant strains, respectively. Conclusions P. aeruginosa multi-drug resistance independently predicted higher hospital costs with a more than 70% increase per admission compared with non-resistant strains. Prevention of the nosocomial emergence and spread of antimicrobial resistant microorganisms is essential to limit the strong economic impact.

Enveloped viruses, e.g. influenza- or varicella viruses may cause highly contagious airborne infections. Their spread is difficult to control, also in hospitals. In the case of influenza and varicella immune prophylaxis and chemotherapy/chemoprophylaxis are possible. This is of particular significance, since varicella and zoster are of increasing importance for immunocompromized patients. Diarrhea is caused to a large extent by viruses. Rotavirus infections play an important role in infancy, and are frequently acquired in the hospital. In a study on infectious gastroenteritis of infants in a hospital we were able to show that 30 percent of all rotavirus infections were of nosocomial origin. Admission of a rotavirus-excreting patient (or personnel) may start a long chain of rotavirus infections on pediatric wards. Even careful hygienic measures in the hospital can hardly prevent the spread of enterovirus infections. Such infections may be severe and lethal for newborns, as shown by us in a study on an outbreak of echovirus 11 disease on a maternity ward. We have recently obtained data on the "stickiness" of enteroviruses on human skin. This could explain essential features of the spread of enteroviruses in the population.

A nosocomial outbreak of bacteraemia, caused by Enterobacter gergoviae infected 11 babies, nine of whom were premature, and was investigated in the neonatal intensive care unit (NICU) of a general hospital in Johor Bahru, Malaysia. The strain that was isolated from the babies was also isolated from the dextrose saline used for the dilution of parenteral antibiotics and from the hands of a healthcare worker on duty in the nursery. Pulsed-field gel electrophoresis (PFGE) of Xba I-digested chromosomal DNA confirmed a possible cross-contamination of parenteral dextrose saline and the healthcare worker. Prompt and effective control measures were initiated within NICU and the nosocomial infection of E. gergoviae was brought to an abrupt end. To the best of our knowledge, this is the first documented outbreak of E. gergoviae in the NICU in a hospital in the state of Johor, Malaysia.

To find out the prevalence of Staphylococcus aureus nosocomial infection and methicillin resistant S. aureus (MRSA), clinical samples from nosocomially infected patients were processed by following standard methodology in microbiology laboratory, Tribhuvan University Teaching Hospital, Kathmandu, Nepal. Of 149 S. aureus isolates, skin infection isolates contributed a major part 72.5% making nosocomial infection by S. aureus most prevalent in skin infection followed by lower respiratory tract infection 11.41% and urinary tract infection 8.7%. Overall MRSA prevalence was 45.0%. MRSA prevalence was 42.6% in skin infection, 82.3% in lower respiratory tract infection and 30.8% in urinary tract infection. MRSA infection was found associated with lower respiratory tract infection only. Highest occurrence of nosocomial infection was observed in female surgical ward, surgical out patient department, orthopedic ward, male surgical ward and maternity ward. MRSA isolation was high from lower respiratory tract of patients admitted in intensive care unit, coronary care unit, Sub-acute intensive care unit, intermediate coronary care unit, neurology ward and post-operative ward. Whereas methicillin sensitive S. aureus (MSSA) occurrence was higher in patients admitted in orthopedic, Surgical out patient department, and female surgical ward. The occurrence of MRSA did not differ with age but MRSA was found associated with male patients and MSSA was associated with female patients. Since MRSA prevalence was high, regular surveillance of MRSA and nosocomial infections should be done and universal precautions to control nosocomial infections should be followed.

Pseudomonas aeruginosan has emerged as an important pathogen elated to serious infections and nosocomial outbreaks worldwide. This study was conducted to understand the prevalence of aminoglycoside (AMG)-resistant P. aeruginosa in our hospital and to provide a scientific basis for control measures against nosocomial infections. Eighty-two strains of P. aeruginosa were isolated from clinical departments and divided into AMG-resistant strains and AMG-sensitive strains based on susceptibility test results. AMG-resistant strains were typed by drug resistance gene typing (DRGT) and protein typing. Five kinds of aminoglycoside-modifying enzyme (AME) genes were detected in the AMG-resistant group. AMG-resistant P. aeruginosa strains were classified into three types and six subtypes by DRGT. Four protein peaks, namely, 9900.02, 7600.04, 9101.25 and 10,372.87 Da, were significantly and differentially expressed between the two groups. AMG-resistant P. aeruginosa strains were also categorised into three types and six subtypes at the distance level of 10 by protein typing. AMG-resistant P. aeruginosa was cloned spread in our hospital; the timely implementation of nosocomial infection prevention and control strategies were needed in preventing outbreaks and epidemic of AMG-resistant P. aeruginosa. SELDI-TOF MS technology can be used for bacterial typing, which provides a new method of clinical epidemiological survey and nosocomial infection control.

Full Text Available among about 10% of hospitalized patients. HAIs increase mortality and morbidity and prolonged hospital stay not to mention considerable costs they impose on the health care system. The present study was conducted in order to evaluate the prevalence of HAIs based on National Nosocomial Infection Surveillance System in hospitals of Mashhad, Iran.  Methods: The current prevalence study of HAI was carried out in 26 hospitals using a protocol updated yearly in Mashhad, Iran. The Centers for Disease Control and Prevention–National Nosocomial Infections Surveillance were used to define four HAIs. All patients admitted to the hospitals during a one-year period (March 1, 2015-February 30, 2016 were recruited in the study. Data was extracted using Iranian nosocomial infection surveillance software.  Results: The overall prevalence rate of HAI in our study was 0.8% among the hospitals with the most frequent HAIs found to be pneumonia (25%, followed by urinary tract infections (20%, and blood stream infections (19%. The highest prevalence rate was observed in 15- to 65-year old patients with more than 50% related to surgical site infection. Also, the most frequently isolated micro-organism was acinetobacter. In addition, the highest seasonal prevalence was seen in winter with pneumonia as the most frequent infection. A total of 4988 pathogens were isolated with 30.33% of clinical confirmation and 69.66% of positive culture.  Conclusion: These findings emphasize the need for appropriate measures for prevention, screening, labeling, and isolation precautions for infected patients.

Purpose: To determine the overall diagnostic accuracy of mononuclear leukocyte- 99m Tc scintigraphy in the routine detection of infectious lesions and fever of unknown origin (FUO) in inpatients. Material and Methods: The use of mononuclear leukocyte 99m Tc scintigraphy is presented in 87 patients who fulfilled the Durack and Street diagnostic criteria of nosocomial FUO; 66 patients were suspected of having infectious lesions (myocarditis, endocarditis, infected catheters, diabetic foot, and osteomyelitis) and 21 patients presented with unknown causes of FUO. Scans were carried out 1, 3, and 24 h after injection of labeled leukocytes. Results: In three cases (3/27) where scintigraphs were negative, biopsies were positive. There were two (2/87) false-positive scintigrams. We found a 95.8% sensitivity and 92.3% specificity. PPV was 93.8%, PPN 94.7%, and accuracy 94.2%. Conclusion: Mononuclear leukocyte 99m Tc scintigraphy showed high sensitivity, specificity, positive and negative predictive values in patients with nosocomial FUO. These results suggest an important role for nuclear medicine in the management of patients with infection/inflammation

Pneumonic plague is one of the clinical forms of plague, of low frequency and high mortality, transmitted by direct inhalation of Yersinia pestis coming from an animal or from person to person. To describe the clinical and epidemiological characteristics of the cases of primary pneumonic plague in an outbreak in the north of Peru. The clinical records of the confirmed cases of primary pneumonic plague presenting in an outbreak occurring in La Libertad, in July 2010, were reviewed, also the search and contact investigation was performed. The index case was identified, as well as three additional cases, out of these, two were nosocomial infections related to the index case. The initial clinical presentation was characterized by sudden onset of fever, chills, myalgia and chest pain, which in less than 24 hours evolved to hypotension and cyanosis. The initiation of specific treatment varied from 2 to 12 days, and cases with prompt initiation of treatment had a better clinical outcome. The lethality was 50% (2/4). Nosocomial transmission of pneumonic plague in Peru is evidenced, with severe clinical manifestations and high lethality.

Background: Patients undergoing open heart surgery have a relatively high risk of acquiring nosocomial infections. The development of antibiotic-resistant infections is associated with prolonged hospital stays and mortalities. Objectives: The present study was conducted to investigate nosocomial infections and the antibiotic resistance pattern in bacteria causing these infections in open heart surgery patients at Imam Ali Hospital in Kermanshah in the west of Iran over a 4-year period from March 2011 to March 2014. Materials and methods: The present cross-sectional study was conducted on 135 cases of nosocomial infection among open heart surgery patients. The demographic characteristics and the risk factors of each case of infection were recorded. The antibiotic susceptibility test was carried out using the Minimum Inhibitory Concentration (MIC) method based on the Clinical and Laboratory Standards Institute (CLSI) protocol. The data collected were then analyzed in SPSS-16. Results: Out of the 6,000 patients who underwent open heart surgery during this 4-year period at the selected hospital, nosocomial infections developed in 135 patients (2.25%), 59.3% of whom were female and 40.7% male. Surgery site infection (SSI), pneumonia (PNEU), urinary tract infection (UTI) and blood stream infection (BSI) affected 52.6%, 37%, 9.6% and 0.8% of the cases, respectively. E.coli , Klebsiella spp. and S. aureus were the most common bacteria causing the nosocomial infections. E. coli was most frequently resistant to imipenem (23.3%) Klebsiella spp. to gentamicin (38.5%) S. aureus to co-trimoxazole (54.2%). Conclusion: SSI had a high prevalence in this study. Further studies should therefore be conducted to examine the risk factors associated with SSI in open heart surgery. Various studies have shown that antibiotic resistance patterns are different in different regions. Finding a definitive treatment therefore requires an antibiogram.

Effect of Bactisporin--a probiotic, containing spores of aerobic Bacillus subtilis 3H bacterium--for complex treatment of patients with nosocomial urinary tract infections was studied. 68 Cultures of different species of conditionally pathogenic bacteria were isolated from urine of the patients. Susceptibility of the isolated cultures to antibiotics before and after application of B. subtilis 3H metabolites was determined. The metabolites were accumulated on potato-glucose agar (PGA) while bacterium was cultivated on kapron membranes placed on surface of the medium. Influence of obtained metabolites on isolated strains was assessed by cultivation of each strain in metabolites-rich PGA during 24 h. Metabolites of B. subtilis led to decrease in resistance of isolated uropathogenic microflora to antibiotics. Use of Bactisporin in complex treatment of nosocomial urinary tract infections resulted in accelerated elimination of causative microorganism.

2004-04-01

To review the evidence on the effects of disinfection of environmental surfaces in hospitals (as compared with cleaning without use of disinfectants) on the occurrence of nosocomial infections. Systematic review of experimental and nonexperimental intervention studies dealing with environmental disinfection or cleaning in different health care settings. A total of 236 scientific articles were identified. None described a meta-analysis, systematic review, or randomized controlled trial. Only 4 articles described completed cohort studies matching the inclusion criteria. None of these studies showed lower infection rates associated with routine disinfection of surfaces (mainly floors) versus cleaning with detergent only. Disinfectants may pose a danger to staff, patients, and the environment and require special safety precautions. However, targeted disinfection of certain environmental surfaces is in certain instances an established component of hospital infection control. Given the complex, multifactorial nature of nosocomial infections, well-designed studies that systematically investigate the role of surface disinfection are required.

To determine clinical characteristics of patients hospitalized in the United Kingdom with pandemic (H1N1) 2009, we studied 1,520 patients in 75 National Health Service hospitals. We characterized patients who acquired influenza nosocomially during the pandemic (H1N1) 2009 outbreak. Of 30 patients, 12 (80%) of 15 adults and 14 (93%) of 15 children had serious underlying illnesses. Only 12 (57%) of 21 patients who received antiviral therapy did so within 48 hours after symptom onset, but 53% needed escalated care or mechanical ventilation; 8 (27%) of 30 died. Despite national guidelines and standardized infection control procedures, nosocomial transmission remains a problem when influenza is prevalent. Health care workers should be routinely offered influenza vaccine, and vaccination should be prioritized for all patients at high risk. Staff should remain alert to the possibility of influenza in patients with complex clinical problems and be ready to institute antiviral therapy while awaiting diagnosis during influenza outbreaks.

Full Text Available Abstract Background It has recently been suggested that serum procalcitonin (PCT is of value in the diagnosis of neonatal sepsis, with varying results. The aim of this prospective multicenter study was to assess the usefulness of PCT as a marker of neonatal sepsis of nosocomial origin. Methods One hundred infants aged between 4 and 28 days of life admitted to the Neonatology Services of 13 acute-care teaching hospitals in Spain over 1-year with clinical suspicion of neonatal sepsis of nosocomial origin were included in the study. Serum PCT concentrations were determined by a specific immunoluminometric assay. The reliability of PCT for the diagnosis of nosocomial neonatal sepsis at the time of suspicion of infection and at 12–24 h and 36–48 h after the onset of symptoms was calculated by receiver-operating characteristics (ROC curves. The Youden's index (sensitivity + specificity - 1 was used for determination of optimal cutoff values of the diagnostic tests in the different postnatal periods. Sensitivity, specificity, and the likelihood ratio of a positive and negative result with the 95% confidence interval (CI were calculated. Results The diagnosis of nosocomial sepsis was confirmed in 61 neonates. Serum PCT concentrations were significantly higher at initial suspicion and at 12–24 h and 36–48 h after the onset of symptoms in neonates with confirmed sepsis than in neonates with clinically suspected but not confirmed sepsis. Optimal PCT thresholds according to ROC curves were 0.59 ng/mL at the time of suspicion of sepsis (sensitivity 81.4%, specificity 80.6%; 1.34 ng/mL within 12–24 h of birth (sensitivity 73.7%, specificity 80.6%, and 0.69 ng/mL within 36–48 h of birth (sensitivity 86.5%, specificity 72.7%. Conclusion Serum PCT concentrations showed a moderate diagnostic reliability for the detection of nosocomial neonatal sepsis from the time of suspicion of infection.

Nosocomial infection control is crucial for improving the quality of medical care. It is also indispensable for implementing effective control measures for severe acute respiratory syndrome (SARS) and the possible occurrence of a human influenza pandemic. The present authors, in collaboration with Vietnamese hospital staff, performed a fact-finding survey of nosocomial infection control in hospitals in northern Vietnam and compared the results with those of a survey conducted 4 years previously. Remarkable improvement was recognized in this period, although there were considerable differences between the central hospitals in Hanoi and local hospitals. In the local hospitals, basic techniques and the systems for infection control were regarded as insufficient, and it is necessary to improve these techniques and systems under the guidance of hospitals in the central area. Based on the results of the survey, programs were prepared and training courses were organized in local hospitals. Evaluation conducted after the training courses showed a high degree of satisfaction among the trainees. The results of the survey and the training courses conducted during the study period are expected to contribute to the improvement of nosocomial infection control in remote areas of Vietnam.

Pfaller, Michael A; Castanheira, Mariana

2016-01-01

Candidemia and other forms of candidiasis are associated with considerable excess mortality and costs. Despite the addition of several new antifungal agents with improved spectrum and potency, the frequency of Candida infection and associated mortality have not decreased in the past two decades. The lack of rapid and sensitive diagnostic tests has led to considerable overuse of antifungal agents resulting in increased costs, selection pressure for resistance, unnecessary drug toxicity, and adverse drug interactions. Both the lack of timely diagnostic tests and emergence of antifungal resistance pose considerable problems for antifungal stewardship. Whereas antifungal stewardship with a focus on nosocomial candidiasis should be able to improve the administration of antifungal therapy in terms of drug selection, proper dose and duration, source control and de-escalation therapy, an important parameter, timeliness of antifungal therapy, remains a victim of slow and insensitive diagnostic tests. Fortunately, new proteomic and molecular diagnostic tools are improving the time to species identification and detection. In this review we will describe the potential impact that rapid diagnostic testing and antifungal stewardship can have on the management of nosocomial candidiasis. © The Author 2015.

Methods: The prospective interventional study was conducted from January 1 to December 31, 2010, at the neonatal intensive care unit (NICU) of the Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkey. Pentaglobin was initiated on the day of diagnosis of nosocomial sepsis to 13 pre-term neonates as a support therapy in addition to antibiotics; 5 ml/kg per day of pentaglobin was infused over a 4-hour period on 3 consecutive days. Clinical and laboratory parametres and major morbidities were recorded before and after pentaglobin treatment and compared using NCSS software. Results: Of the total, 8(66%) were females and 5 (40%) males. Following pentaglobin therapy, the immature-to-total neutrophil ratio and C-reactive protein levels were significantly decreased, and the capillary pH and base excess were significantly increased (p 0.05). Coagulase-negative staphylococci (n=3; 23%), Klebsiella pneumoniae (n=2; 15.3%), and Pseudomonas aeruginosa (n=1; 7.7%) were identified in blood cultures. The presence of intraventricular haemorrhages, necrotising enterocolitis, periventricular leukomalacia, and patent ductus arteriosus was not changed following the treatment. Adverse effects and mortality were not observed during or after the therapy. Conclusion: Pentaglobin treatment of nosocomial sepsis could be used as an adjunct therapy without any adverse short-term reactions, even in very low birthweight pre-term infants. (author)

Infection prevention (IP) measures are vital to prevent (nosocomial) outbreaks. Financial evaluations of these are scarce. An incremental cost analysis for an academic IP unit was performed. On a yearly basis, we evaluated: IP measures; costs thereof; numbers of patients at risk for causing nosocomial outbreaks; predicted outbreak patients; and actual outbreak patients. IP costs rose on average yearly with €150,000; however, more IP actions were undertaken. Numbers of patients colonized with high-risk microorganisms increased. The trend of actual outbreak patients remained stable. Predicted prevented outbreak patients saved costs, leading to a positive return on investment of 1.94. This study shows that investments in IP can prevent outbreak cases, thereby saving enough money to earn back these investments.

Background Nosocomial bloodstream infections (nBSIs) are an important cause of morbidity and mortality and are the most frequent type of nosocomial infection in pediatric patients. Methods We identified the predominant pathogens and antimicrobial susceptibilities of nosocomial bloodstream isolates in pediatric patients (≤16 years of age) in the Brazilian Prospective Surveillance for nBSIs at 16 hospitals from 12 June 2007 to 31 March 2010 (Br SCOPE project). Results In our study a total of 2,563 cases of nBSI were reported by hospitals participating in the Br SCOPE project. Among these, 342 clinically significant episodes of BSI were identified in pediatric patients (≤16 years of age). Ninety-six percent of BSIs were monomicrobial. Gram-negative organisms caused 49.0% of these BSIs, Gram-positive organisms caused 42.6%, and fungi caused 8.4%. The most common pathogens were Coagulase-negative staphylococci (CoNS) (21.3%), Klebsiella spp. (15.7%), Staphylococcus aureus (10.6%), and Acinetobacter spp. (9.2%). The crude mortality was 21.6% (74 of 342). Forty-five percent of nBSIs occurred in a pediatric or neonatal intensive-care unit (ICU). The most frequent underlying conditions were malignancy, in 95 patients (27.8%). Among the potential factors predisposing patients to BSI, central venous catheters were the most frequent (66.4%). Methicillin resistance was detected in 37 S. aureus isolates (27.1%). Of the Klebsiella spp. isolates, 43.2% were resistant to ceftriaxone. Of the Acinetobacter spp. and Pseudomonas aeruginosa isolates, 42.9% and 21.4%, respectively, were resistant to imipenem. Conclusions In our multicenter study, we found a high mortality and a large proportion of gram-negative bacilli with elevated levels of resistance in pediatric patients. PMID:23861860

To examine the cost-effectiveness of vancomycin versus linezolid in the empiric treatment of nosocomial pneumonias incorporating results from a recent prospective, double-blind, multicenter, controlled trial in adults with suspected methicillin-resistant Staphylococcus aureus (MRSA) nosocomial pneumonia. A decision-analytic model examining the cost-effectiveness of linezolid versus vancomycin for the empiric treatment of nosocomial pneumonia was created. Publicly available cost, efficacy, and utility data populated relevant model variables. A probabilistic sensitivity analysis varied parameters in 10,000 Monte-Carlo simulations, and univariate sensitivity analyses assessed the impact of model uncertainties and the robustness of our conclusions. Results indicated that the cost per quality-adjusted life-year (QALY) increased 6% ($22,594 vs. $23,860) by using linezolid versus vancomycin for nosocomial pneumonia. The incremental cost per QALY gained by using linezolid over vancomycin was $6,089, and the incremental cost per life saved was $68,615 with the use of linezolid. Vancomycin dominated linezolid in the subset of patients with documented MRSA. The incremental cost per QALY gained using linezolid if no mortality benefit exists between agents or a 60-day time horizon was analyzed was $19,608,688 and $443,662, respectively. Linezolid may be a cost-effective alternative to vancomycin in the empiric treatment of patients with suspected MRSA nosocomial pneumonia; however, results of our model were highly variable on a number of important variables and assumptions including mortality differences and time frame analyzed.

A 1 year prospective study on routine gowning before entering a neonatal unit was conducted in a maternity hospital in Singapore. This study was done based on previous work by Donowitz, Haque and Chagla and Agbayani et al., as there have been no known studies done in Singapore. The aim of the study was to test the hypothesis that routine gowning before entering a neonatal nursery does not reduce nosocomial infection and mortality rate. A total of 212 neonates from the neonatal intensive care unit (NICU) and 1694 neonates from the neonatal special care unit (NSCU) were studied. Neonates admitted during the 1 year study were assigned to the gowning (control) and no routine gowning (trial) group on every alternate 2 months. The hospital infection control nurse provided data on nosocomial infection. The overall nosocomial infection rate in the NICU was 24% (25 of 104 admissions) during gowning periods compared to 16.6% (18 of 108 admissions) when plastic aprons were not worn before entry. In the NSCU, the overall infection rate was 1.5% (12 of 800 admissions) during gowning periods compared to 2.1% (19 of 894 admissions) when no gown was worn before entry. Results of the study found no significant differences in the incidences of nosocomial infection and mortality in the neonates. The cost of gowns used during the no routine gowning periods was S$2012.8 compared to S$3708 used during the routine gowning procedure. The investigators recommend that routine gowning before entering a neonatal unit is not essential and cost effective for the purpose of reducing infection. Rather the focus should be on adequate handwashing by all hospital personnel and visitors before handling neonates.

Purpose: To determine the overall diagnostic accuracy of mononuclear leukocyte-{sup 99m}Tc scintigraphy in the routine detection of infectious lesions and fever of unknown origin (FUO) in inpatients. Material and Methods: The use of mononuclear leukocyte {sup 99m}Tc scintigraphy is presented in 87 patients who fulfilled the Durack and Street diagnostic criteria of nosocomial FUO; 66 patients were suspected of having infectious lesions (myocarditis, endocarditis, infected catheters, diabetic foot, and osteomyelitis) and 21 patients presented with unknown causes of FUO. Scans were carried out 1, 3, and 24 h after injection of labeled leukocytes. Results: In three cases (3/27) where scintigraphs were negative, biopsies were positive. There were two (2/87) false-positive scintigrams. We found a 95.8% sensitivity and 92.3% specificity. PPV was 93.8%, PPN 94.7%, and accuracy 94.2%. Conclusion: Mononuclear leukocyte {sup 99m}Tc scintigraphy showed high sensitivity, specificity, positive and negative predictive values in patients with nosocomial FUO. These results suggest an important role for nuclear medicine in the management of patients with infection/inflammation.

Full Text Available Background. It is a fact that hand hygiene prevents nosocomial infection, but compliance with recommended instructions is commonly poor. The purpose of this study was to implement a hand hygiene program for increase compliance with hand hygiene and its relationship with nosocomial infection (NI and MRSA infection/colonization rates. Methods. Compliance to hand hygiene was evaluated in a hospital by direct observation and measured of health care-associated infections, including methicillin resistant Staphylococcus aureus, before and after an educational intervention, using visual poster, colorful stamps, and feedback of the results. Results. Overall compliance did not increase during intervention, only handwashing before and after patient contact has improved from 40% to 76% (=0.01 for HCWs, but NI and MRSA rates remained high and stable. Conclusion. In a combination of high prevalence of NI and low compliance to hand hygiene, the programme of measure does not motivate the HCW hand hygiene. Future interventions should employ incremental evaluation to develop effective hand hygiene initiatives.

Full Text Available The paper presents the results of using the fourth-generation cephalosporin maxicef in the treatment of 20 patients with nosocomial pneumonia and severe concomitant injury. A control group comprised 20 patients receiving a combination of ceftazidime and amikacin. The total efficiency of the antibacterial therapy was 68.5% in the maxicef group and 40.9% in the control group (р<0.05. The therapy had to be modified in 42% of the maxicef group and in 72.7% in the control group (р<0.05. The average treatment cost was US $518 (429—606 and US $482 (368—596 in the maxicef and control groups, respectively. Nephrotoxicity was observed in 9% of the patients receiving a combination of the antibiotics. The activity of maxicef was also analyzed in vitro. Results. Maxicef was demonstrated to be highly active against the majority of gram-negative and gram-positive bacteria in vitro. Its efficacy against the most common bacteria (P.aeruginosa, S.aureus, E.coli, K.pneumonia causing infections in severe injury was in vitro significantly higher than that of ceftazidime. The comparative study indicates that the fourth-generation cephalosporin maxicef may be used as an alternative to the standard combined therapy. Key words: concomitant injury, maxicef, nosocomial pneumonia, a combination of ceftazidime and aminoglycoside, nosocomial infection pathogens.

Hospital-acquired influenza: a synthesis using the Outbreak Reports and Intervention Studies of Nosocomial Infection (ORION) statement.

Voirin, N; Barret, B; Metzger, M-H; Vanhems, P

2009-01-01

Nosocomial influenza outbreaks occur in almost all types of hospital wards, and their consequences for patients and hospitals in terms of morbidity, mortality and costs are considerable. The source of infection is often unknown, since any patient, healthcare worker (HCW) or visitor is capable of transmitting it to susceptible persons within hospitals. Nosocomial influenza outbreak investigations should help to identify the source of infection, prevent additional cases, and increase our knowledge of disease control to face future outbreaks. However, such outbreaks are probably underdetected and underreported, making routes of transmission difficult to track and describe with precision. In addition, the absence of standardised information in the literature limits comparison between studies and better understanding of disease dynamics. In this study, reports of nosocomial influenza outbreaks are synthesised according to the ORION guidelines to highlight existing knowledge in relation to the detection of influenza cases, evidence of transmission between patients and HCWs and measures of disease incidence. Although a body of evidence has confirmed that influenza spreads within hospitals, we should improve clinical and virological confirmation and initiate active surveillance and quantitative studies to determine incidence rates in order to assess the risk to patients.

Full Text Available Abstract Background Vancomycin-resistant enterococci (VRE are among the most common antimicrobial-resistant pathogens causing nosocomial infections. Although antibiotic use has been identified as a risk factor for VRE, it remains unclear which antimicrobial agents particularly facilitate VRE selection. Here, we assessed whether use of specific antimicrobial agents is independently associated with healthcare-associated (HA VRE rates in a university hospital setting in Berlin, Germany. Methods We conducted the study between January 2014 and December 2015 at the Charité-university hospital of Berlin, Germany. From the hospital pharmacy, we extracted data for all antibacterials for systemic use (anatomical therapeutic chemical (ATC-classification J01 and calculated ward specific antibiotic consumption in defined daily doses (DDDs per 100 patient-days (PD. We used the microbiology laboratory database to identify all patients with isolation of invasive or non-invasive VRE and calculated HA-VRE incidence as nosocomial VRE-cases per 100 patients and HA-VRE incidence density as nosocomial VRE-cases per 1000 PD. We defined VRE isolates as hospital-acquired if they were identified three days or later after hospital admission and otherwise as community-acquired (CA-VRE. We performed univariable and multivariable regression analyses to estimate the association of the frequency of HA-VRE per month with antibiotic use and other parameters such as length of stay, type of ward or presence of at least one CA-VRE on ward. In a second analysis, we considered only patients with VRE infections. Results We included data from 204,054 patients with 948,380 PD from 61 wards. Overall, 1430 VRE-cases were identified of which 409 (28.6% were considered hospital-acquired (HA. We found that carbapenem use in the current month and prior-month use of glycopeptides increased the risk for HA-VRE by 1% per 1 DDD/100 PD and 3% per 1 DDD/100 PD, respectively.

Invasive fungal infection is an important cause of morbimortality in patients with severe burns. The advances in burn care therapy have considerably extended the survival of seriously burned patients, exposing them to infectious complications, notably fungal infections, with increased recognition of invasive infections caused by Candida species. However, some opportunistic fungi, like Trichosporon asahii, have emerged as important causes of nosocomial infection. A case of nosocomial infection due to T. asahii in a severely ill burned patient successfully treated with voriconazole is presented. The management of invasive fungal infections in burned patients, from diagnosis to selection of the therapeutic protocol, is often a challenge. Early diagnosis and treatment are associated with a better prognosis. In this case report, current treatment options are discussed, and a review of previously published cases is presented. Due to the difficulty in the diagnosis of invasive mycoses and their high associated mortality rates, it is advisable to keep a high degree of clinical suspicion of trichosporonosis in susceptible patients, including burned patients. The isolation of T. asahii in clinical specimens of this type of host must raise clinical alert, since it may precede an invasive infection. Copyright © 2014 Revista Iberoamericana de Micología.

The bacterial infection on film cassette contact surface was examined at the diagnostic radiology department of the S. hospital. The objective of this study was to assess the contamination level on film cassette contact surface as a predictor of patient prevention from nosocomial infection and for improvement of the hospital environment. The laboratory result was identified non-pathologic bacterial in the five different cassette size of the contact surface. Film cassettes were exposed to ultraviolet light for 1, 2 and 3 minutes. Ultraviolet light disinfection is proven suitable for bacterial. The study concludes that presence of a bacterial infection will prevent a using antiseptic technique on film cassette contact surface. In addition education of nosocomial infection for radiographers will be required. In conclusion, ultraviolet is considered effective to irradiate bacterial. Additionally, two minutes are required to sterilize film cassettes

The bacterial infection on film cassette contact surface was examined at the diagnostic radiology department of the S. hospital. The objective of this study was to assess the contamination level on film cassette contact surface as a predictor of patient prevention from nosocomial infection and for improvement of the hospital environment. The laboratory result was identified non-pathologic bacterial in the five different cassette size of the contact surface. Film cassettes were exposed to ultraviolet light for 1, 2 and 3 minutes. Ultraviolet light disinfection is proven suitable for bacterial. The study concludes that presence of a bacterial infection will prevent a using antiseptic technique on film cassette contact surface. In addition education of nosocomial infection for radiographers will be required. In conclusion, ultraviolet is considered effective to irradiate bacterial. Additionally, two minutes are required to sterilize film cassettes.

To estimate and compare the economic costs for the care of patients with and without nosocomial pneumonia at Hospital II Huánuco EsSalud during 2009-2011, in Peru. This was a partial economic evaluation of paired cases and controls. A collection sheet was used. nosocomial pneumonia. direct health costs, direct non-health costs, indirect costs, occupation, age, comorbidities, sex, origin, and education level. A bivariate analysis was performed. Forty pairs of cases and controls were identified. These patients were hospitalized for >2 weeks and prescribed more than two antibiotics. The associated direct health costs included those for hospitalization, antibiotics, auxiliary examinations, specialized assessments, and other medications. The direct non-health costs and associated indirect costs included those for transportation, food, housing, foregone payroll revenue, foregone professional fee revenue, extra-institutional expenses, and payment to caregivers during hospitalization and by telephone. The direct health costs for nosocomial pneumonia patients were more than three times and the indirect costs were more than two times higher than those for the controls. Variables with the greatest impact on costs were identified.

Forty-two community and general hospitals in central Thailand. To examine the adequacy of indoor ventilation for nosocomial tuberculosis (TB) prevention in public hospitals in central Thailand. A cross-sectional survey was conducted among 323 patient care and ancillary areas in the target hospitals. Data on indoor ventilation rate were collected by the tracer gas method and reported as air changes per hour (ACH). The adequacy of the measured ventilation rates were then determined by comparison with the international recommended standard values. Indoor ventilation rates were inadequate in almost half of the studied areas (144/323, 44.6%). The inadequacy was particularly serious in the emergency rooms (ERs) and radiological areas, where 73.8% (31/42 each) of the rooms had ACH below the recommended standards. Detailed analysis showed that most of the rooms with natural ventilation had air exchange rates that exceeded the recommended standards, while the opposite was the case for rooms with air-conditioning, particularly the window or wall-mount type. Indoor ventilation in high-risk nosocomial TB areas in public hospitals in Thailand was inadequate due to the installation of air-conditioning systems in modern buildings.

Full Text Available Abstract Background To investigate the impact of weekly screening within the bundle of infection control measures to terminate vancomycin-resistant enterococci (VRE transmissions on an oncologic ward. Methods A cluster of 12 VRE colonisation and five infections was detected on an oncologic ward between January and April 2015. Subsequently, the VRE point prevalence was detected and, as part of a the bundle of infection control strategies to terminate the VRE cluster, we isolated affected patients, performed hand hygiene training among staff on ward, increased observations by infection control specialists, intensified surface disinfection, used personal protective equipment and initiated an admission screening in May 2015. After a further nosocomial VRE infection in August 2015, a weekly screening strategy of all oncology patients on the respective ward was established while admission screening was continued. Whole genome sequencing (WGS-based typing was applied to determine the clonal relationship of isolated strains. Results Initially, 12 of 29 patients were VRE colonised; of these 10 were hospital-acquired. During May to August, on average 7 of 40 patients were detected to be VRE colonised per week during the admission screening, showing no significant decline compared to the initial situation. WGS-based typing revealed five different clusters of which three were due to vanB- and two vanA-positive enterococci. After an additional weekly screening was established, the number of colonised patients significantly declined to 1/53 and no further nosocomial cases were detected. Conclusions Weekly screening helped to differentiate between nosocomial and community-acquired VRE cases resulting in earlier infection control strategies on epidemic situations for a successful termination of nosocomial VRE transmissions.

Resumen

El surfactante pulmonar es una sustancia tensoactiva producida por los neumocitos tipo II, cuya concentración en el recién nacido prematuro/ inmaduro está disminuída, llevando a la producción del síndrome de dificultad respiratoria. El surfactante está constituído en un 85% por lípidos, del tipo fosfolípidos en su mayoría. El resto son proteínas surfactantes.

Los fosfogliceridos (lecitinas y la esfingomielina forman el grupo de fosfolipidos involucrados. La fosfatidil colina y la dipalmitoil fosfatidil colina son las lecitinas más abundantes en el líquido extracelular que recubre los alvéolos pulmonares normales y en el surfactante pulmonar que disminuye su tensión superficial. Así se evita la atelectasia al final de la fase espiratoria de la respiración. En el neumocito II, enzimas remodelan las diferentes lecitinas para convertirlas en dipalmitoil fosfatidil colina.

Una vez que el surfactante es producido en el neumocito, esta substancia migra como “cuerpos la melares” desde el núcleo hasta la superficie apical de la célula desde donde es liberado por exocitosis dentro del alveolo.

Menos de un 0.1% de los recién nacidos presentan Síndrome de Dificultad Respiratoria (llamado antiguamente Enfermedad de Membrana Hialina cada año, y alrededor de un 10 % de estos mueren. La administracion de corticoesteroides incrementa la madurez pulmonar en casos de riesgo de parto prematuro, o cuando es necesario realizar una cesárea lo más temprano posible. El tratamiento de los bebes prematuros que presentan SDR incluye la administración de surfactantes dentro del árbol traqueobronquial.

El patrón oro de la determinación de madurez pulmonar fetal es la relación lecitina/esfingomielina (L/E, aunque hay algunas otras pruebas como la medición de cuerpos la melares, que resultan confiables, económicas y más fácilmente disponibles en hospitales de menor categor

We compared the economic impacts of linezolid and vancomycin for the treatment of hospitalized patients with methicillin-resistant Staphylococcus aureus (MRSA)-confirmed nosocomial pneumonia. We used a 4-week decision tree model incorporating published data and expert opinion on clinical parameters, resource use and costs (in 2012 US dollars), such as efficacy, mortality, serious adverse events, treatment duration and length of hospital stay. The results presented are from a US payer perspective. The base case first-line treatment duration for patients with MRSA-confirmed nosocomial pneumonia was 10 days. Clinical treatment success (used for the cost-effectiveness ratio) and failure due to lack of efficacy, serious adverse events or mortality were possible clinical outcomes that could impact costs. Cost of treatment and incremental cost-effectiveness per successfully treated patient were calculated for linezolid versus vancomycin. Univariate (one-way) and probabilistic sensitivity analyses were conducted. The model allowed us to calculate the total base case inpatient costs as $46,168 (linezolid) and $46,992 (vancomycin). The incremental cost-effectiveness ratio favored linezolid (versus vancomycin), with lower costs ($824 less) and greater efficacy (+2.7% absolute difference in the proportion of patients successfully treated for MRSA nosocomial pneumonia). Approximately 80% of the total treatment costs were attributed to hospital stay (primarily in the intensive care unit). The results of our probabilistic sensitivity analysis indicated that linezolid is the cost-effective alternative under varying willingness to pay thresholds. These model results show that linezolid has a favorable incremental cost-effectiveness ratio compared to vancomycin for MRSA-confirmed nosocomial pneumonia, largely attributable to the higher clinical trial response rate of patients treated with linezolid. The higher drug acquisition cost of linezolid was offset by lower treatment failure

Acinetobacter species remain alive in hospitals on various surfaces, both dry and moist, forming an important source of hospital infections. These bacteria are naturally resistant to many antibiotic classes. Although the role of the quorum sensing system in regulating the virulence factors of Acinetobacter species has not been fully elucidated, it has been reported that they play a role in bacterial biofilm formation. The biofilm formation helps them to survive under unfavorable growth conditions and antimicrobial treatments. It is based on the accumulation of bacterial communication signal molecules in the area. In this study, we compared the bacterial signal molecules of 50 nosocomial Acinetobacter baumannii strain and 20 A. baumannii strain isolated from soil. The signal molecules were detected by the biosensor bacteria (Chromobacterium violaceum 026, Agrobacterium tumefaciens A136, and Agrobacterium tumefaciens NTL1) and their separation was determined by thin-layer chromatography. As a result, it has been found that soil-borne isolates can produce 3-oxo-C8-AHL and C8-AHL, whereas nosocomial-derived isolates can produce long-chain signals such as C10-AHL, C12-AHL, C14-AHL and C16-AHL. According to these results, it is possible to understand that these signal molecules are found in the infection caused by A. baumannii. The inhibition of this signaling molecules in a communication could use to prevent multiple antibiotic resistance of these bacteria.

Pseudomonas aeruginosa is well-recognized as a nosocomial pathogen, which exhibits inherent drug resistance. In this study, the antibacterial activity of ethanol extracts of 58 Chinese herbal medicines used in Taiwan were tested against 89 nosocomial antibiotic resistant strains of Pseudomonas aeruginosa. The results gathered by the disc diffusion method showed that 26 out of the 58 herbal extracts exhibited antibacterial activity. Among the 26 herbal extracts, 10 extracts showed broad-spectrum antibacterial activities and were selected for further antibacterial property assay. The minimum inhibitory concentrations (MIC) of the active partition fractions ranged from 0.25 to 11.0 mg/L. The presence of flavonoid compounds in the active fractions of test herbal extracts was observed by the TLC-bioautography. The results from the time-kill assay revealed that most of the herbal extracts completely killed the test organisms within 4 hours. Exposure of the test strains to a sub-MIC level of the herbal extracts for 10 consecutive subcultures did not induce resistance to the active components. A combination of the active herbal fractions with antibiotics showed that one of the herbal medicines, the hexane fraction of Ramulus Cinnamomi, possessed a synergistic effect with tetracycline, gentamycin, and streptomycin. In conclusion, the tested Chinese medical herbs have the potential to be developed into natural antibiotics. This is the first evaluation for screening large amounts of medical plants against nosocomial antibiotic resistant bacteria in Taiwan.

In Intertropical Africa hospitalized patients are exposed to a risk of nosocomial infections. The dearth of published data on this subject limits the descriptive analysis of the situation. This study aimed to determine the incidence, the germs responsible for these infections and the risk factors of nosocomial infections in the Maternity Ward at the General Referral Hospital in Katuba, Lubumbashi, Democratic Republic of the Congo. We conducted a descriptive, longitudinal study from 1 October 2014 to 1 January 2015. Our study population consisted of 207 women who had been hospitalized in the Maternity Ward at the General Referral Hospital in Katuba. We carried out a comprehensive data collection. Nosocomial infection rate accounted for 15.5%. Parturient women who had been hospitalized for more than three days were three times more likely to develop a nosocomial infection (p=0.003), while those who had had a complicated delivery were four times more likely to be at risk of developing nosocomial infection (p = 0.000). Escherichia coli was the most isolated causative agent (38.1%), followed by Citrobacter freundi (23.8%), Acinobacter baumani (.18, 2%), Staphylococcus aureus (18.2%), Enterococcus aureus (14.3%) and Pseudomonas aeroginosa (9.1%). Ampicillin was the most prescribed antibiotic, to which isolated microbes were resistant. It is necessary to improve hospital hygiene and to conduct further study to examine the similarity between germs strains in the environment and those in biological fluids.

Controlling nosocomial infection based on structure of hospital social networks.

Nosocomial infection (i.e. infection in healthcare facilities) raises a serious public health problem, as implied by the existence of pathogens characteristic to healthcare facilities such as methicillin-resistant Staphylococcus aureus and hospital-mediated outbreaks of influenza and severe acute respiratory syndrome. For general communities, epidemic modeling based on social networks is being recognized as a useful tool. However, disease propagation may occur in a healthcare facility in a manner different from that in a urban community setting due to different network architecture. We simulate stochastic susceptible-infected-recovered dynamics on social networks, which are based on observations in a hospital in Tokyo, to explore effective containment strategies against nosocomial infection. The observed social networks in the hospital have hierarchical and modular structure in which dense substructure such as departments, wards, and rooms, are globally but only loosely connected, and do not reveal extremely right-skewed distributions of the number of contacts per individual. We show that healthcare workers, particularly medical doctors, are main vectors (i.e. transmitters) of diseases on these networks. Intervention methods that restrict interaction between medical doctors and their visits to different wards shrink the final epidemic size more than intervention methods that directly protect patients, such as isolating patients in single rooms. By the same token, vaccinating doctors with priority rather than patients or nurses is more effective. Finally, vaccinating individuals with large betweenness centrality (frequency of mediating connection between pairs of individuals along the shortest paths) is superior to vaccinating ones with large connectedness to others or randomly chosen individuals, which was suggested by previous model studies.

Nosocomial Infection (NI) is also observed in healthcare facilities in non-Western countries. The purpose of this report is to describe the findings of a survey undertaken to evaluate hygiene procedures implemented at the "Hopital Principal" in Dakar, Senegal and to assess perception and awareness of nosocomial risk among the hospital staff. A total of 264 healthcare workers were interviewed. Mean age was 39 years (range, 18-60) and the sex ratio was 1.3 (150 men/114 women). Sixty (22.7%) had university degrees, 106 (40.2%) had secondary school diplomas, 50 (18.9%) had attended middle school, and 13 (4.9%) had no schooling. Analysis of interview data showed that 56.1% (157/264) defined NI as infection acquired at the hospital but that only 9.8% (n=26) knew that a minimum 48-hour delay was necessary to distinguish nosocomial from community acquired infection. While understanding about NI was correlated with education level, data showed that 1 out of 3 physicians (13/39) failed to give the exact definition. Hand contact was cited as the second route of transmission. Isolation precautions were understood by 22.7% of personnel (60/264). Systematic handwashing was reported by 363% (96/264) but observation demonstrated that it was not performed properly regardless of the category of personnel. Care protocols were understood by 54.6% of persons interviewed (144/264). A hygiene-training course had been attended by 52.2% (n=138). Two thirds of the staff (69.7%: 54/264) was able to identify the hygiene nurse. Ninety-eight health care providers (37.1%) were familiar with the CLIN (Comités de Lutte contre les Infections Nosocomiales).

This study reports a two-year programme of attempted eradication of Legionella colonization in the potable water supply of a 1000-bed tertiary care teaching hospital in Wales. There was a simultaneous, point-of-care, sterile-water-only policy for all intensive care units (ICU) and bone marrow and renal transplant units in order to prevent acquisition of nosocomial Legionnaires' disease. The programme was initiated following a case of nosocomial pneumonia caused by Legionella pneumophila serogroup 1-Bellingham-like genotype A on the cardiac ICU. The case occurred 14 days after mitral and aortic valve replacement surgery. Clinical and epidemiological investigations implicated aspiration of hospital potable water as the mechanism of infection. Despite interventions with chlorine dioxide costing over 25000 UK pounds per annum, Legionella has remained persistently present in significant numbers (up to 20000 colony forming units/L) and with little reduction in the number of positive sites. Two further cases of nosocomial disease occurred over the following two-year period; in one case, aspiration of tap water was implicated again, and in the other case, instillation of contaminated water into the right main bronchus via a misplaced nasogastric tube was implicated. These cases arose because of inadvertent non-compliance with the sterile-water-only policy in high-risk locations. Enhanced clinical surveillance over the same two-year period detected no other cases of nosocomial disease. This study suggests that attempts at eradication of Legionella spp. from complex water systems may not be a cost-effective measure for prevention of nosocomial infections, and to the best of our knowledge is the first study from the UK to suggest that the introduction of a sterile-water-only policy for ICUs and other high-risk units may be a more cost-effective approach.

El nucléolo como un regulador del envejecimiento celular The nucleolus as a regulator of cellular senescence

Full Text Available El nucléolo, considerado únicamente como el sitio de síntesis de los ribosomas, actualmente representa una estructura nuclear dinámica que participa en la regulación de importantes procesos celulares. Numerosas evidencias han demostrado que el envejecimiento celular es una de las diversas funciones que son controladas por el nucléolo. Las mutaciones en las proteínas de localización nucleolar promueven el envejecimiento prematuro en levaduras y humanos. La carencia de represión en la transcripción de genes que codifican para el ARNr que se encuentran dañados, y las mutaciones en las helicasas del ADN encargadas de minimizar la formación de círculos extra-cromosómicos del ADN que codifica para el ARNr, provocan modificaciones en la estructura del nucléolo e inducen envejecimiento prematuro en levaduras. De igual manera, en los humanos la carencia de las helicasas del ADN localizadas en el nucléolo y que participan en el mantenimiento de la integridad genómica, favorecen el desarrollo de aquellas enfermedades asociadas con el envejecimiento acelerado. Además, la presencia de algunos componentes de la telomerasa en el nucléolo, indica que parte de la biosíntesis de esta enzima se realiza en esta estructura nuclear, sugiriendo una conexión entre el nucléolo y la síntesis de los telómeros en la regulación del envejecimiento celular. Por otra parte, el nucléolo secuestra proteínas para regular su actividad biológica durante el inicio o término de la vida replicativa celular.The nucleolus has been considered originally only as the site for the ribosome synthesis, but now it is well known that it represents a dynamic nuclear structure involved in important cellular processes.

Nosocomial outbreaks of Legionnaires disease have been linked to contaminated water in hospitals. Immunocompromised patients are particularly vulnerable and, when infected, have a high mortality rate. We report the investigation of a cluster of cases of nosocomial pneumonia attributable to Legionella pneumophila serogroup 1 that occurred among patients on our stem cell transplantation unit. We conducted a record review to identify common points of potential exposure, followed by environmental and water sampling for Legionella species from those sources. We used an air sampler to in an attempt to detect aerosolized Legionella and pulsed-field gel electrophoresis to compare clinical and environmental isolates. The most likely sources identified were the water supply in the patients' rooms and a decorative fountain in the radiation oncology suite. Samples from the patients' rooms did not grow Legionella species. Cultures of the fountain, which had been restarted 4 months earlier after being shut off for 5 months, yielded L. pneumophila serogroup 1. The isolates from both patients and the fountain were identical by pulsed-field gel electrophoresis. Both patients developed pneumonia within 10 days of completing radiation therapy, and each reported having observed the fountain at close range. Both patients' infections were identified early and treated promptly, and both recovered. This cluster was caused by contamination of a decorative fountain despite its being equipped with a filter and ozone generator. Fountains are a potential source of nosocomial Legionnaires disease despite standard maintenance and sanitizing measures. In our opinion, fountains present unacceptable risk in hospitals serving immunocompromised patients.

Bacterial resistance is a growing health problem worldwide that has serious economic and social impacts, compromising public health, and the therapeutic action of current antibiotics. Therefore, the search for new compounds with antimicrobial properties is relevant in modern studies, particularly against bacteria of clinical interest. In the present study, in vitro antibacterial activity of the ethanol extract and essential oil of Curcuma longa (Zingiberaceae) was evaluated against nosocomial bacteria, using the microdilution method. Escherichia coli strains, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus sp. were used, Salmonella sp. and Bacillus sp., isolated from nosocomial infections in a hospital in the city of Monteria and reference strains of S. aureus ATCC 43300, S. aureus ATCC 29213, S. aureus ATCC 25923, P. aeruginosa ATCC 27853, E. coli ATCC 25922 and K. pneumonia ATCC 700603. The ethanol extract antibacterial profile was more efficient at higher concentrations (1 000 ppm), obtaining significant percentages of reduction of more than 50 % against K. pneumoniae ATCC 700603 and a clinical isolate of E. coli; while compared to Bacillus clinical isolate, was more active than the essential oil. For the rest of microorganisms, the reduction percentages obtained at a concentration of 1 000 ppm varied between 17 and 42 % with ethanolic extract, and 8 to 43 % with essential oil. At concentrations of 100 and 500 ppm antibacterial activity of the extracts was lower. The results indicated that the ethanolic extract and essential oil of C. longa rhizomes have active compounds with antibacterial properties that could be used in future research as a therapeutic alternative for the treatment of infections caused by nosocomial pathogens.

Nosocomial outbreaks of Salmonella infections in Australia are an infrequent but significant source of morbidity and mortality. Such an outbreak results in direct, measurable expenses for acute care management, as well as numerous indirect (and less quantifiable) costs to those affected, the hospital, and the wider community. This article describes the significant direct costs incurred as a result of a nosocomial outbreak of Salmonella infection involving patients and staff. Information on costs incurred by the hospital was gathered from a number of sources. The data were grouped into 4 sections (medical costs, investigative costs, lost productivity costs, and miscellaneous) with use of an existing tool for calculating the economic impact of foodborne illness. The outbreak cost the hospital more than AU $120, 000. (US $95,000). This amount is independent of more substantial indirect costs. Salmonella infections are preventable. Measures to aid the prevention of costly outbreaks of nosocomial salmonellosis, although available, require an investment of both time and money. We suggest that dedication of limited resources toward such preventive strategies as education is a practical and cost-effective option for health care facilities.

The majority of nosocomial infections in Taiwan hospitals are caused by drug-resistant Gram-negative bacteria (GNB), including Pseudomonas aeruginosa, Acinetobacter baumannii, and various species of Enterobacteriaceae. Carbapenems are important agents for treating infections caused by these GNB. Recently, doripenem was approved for use in Taiwan in August 2009. However, data on its in vitro activity against nosocomial GNB isolated from Taiwan remain limited. The study was designed to look into this clinical issue. A total of 400 nonduplicated nosocomial blood isolates isolated in 2009, inclusive of P. aeruginosa (n = 100), A. baumannii (n = 100), and Enterobacteriaceae (n = 200), were randomly selected from the bacterial bank preserved at National Taiwan University Hospital. Susceptibilities of these 400 isolates to various antibiotics, including doripenem, imipenem, meropenem, ceftazidime, amikacin, ciprofloxacin, colistin, and tigecycline were determined by using Etest. Doripenem demonstrated similar in vitro activity to imipenem and meropenem against P. aeruginosa (87%, vs. 85% and 89%), A. baumannii (56%, vs. 60% and 60%), and Enterobacteriaceae (100%, vs. 98.5% and 99.5%). The prevalence of carbapenem-resistant (any one of three tested carbapenems) P. aeruginosa, A. baumannii, and Enterobacteriaceae isolates was 15%, 44%, and 0.5%, respectively. Doripenem was as effective as imipenem and meropenem in our study. However, there was a significant proportion of carbapenem resistance among the tested isolates. Hence, longitudinal surveillance is necessary to monitor the resistance trend. Copyright © 2012. Published by Elsevier B.V.

Tobacco plays an important role in international trade as one of the export commodities. Indonesia is one of the good quality export contributors of tobacco leaves in the world. Nevertheless, tobacco is used only as a raw material for the cigarette industries, and the rise on anti-cigarette regulations prompted the exploration of alternative product from tobacco plants. The content of alkaloids, flavonoids, terpenoids and steroids in tobacco leaves were reported in literatures as antibacterial. Therefore, this study proposed in vitro assay of the ethanolic heat reflux extract (EHRE) of Nicotiana tabacum var. Virginia against nosocomial bacteria pathogen ((Pseudomonas aeruginosa (ATCC 27853), Eschericia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), Enterococcus faecalis (ATCC 29212)). Kirby-bauer diffusion method was used for this assay. The concentration of the EHRE for Kirby-bauer assay were 20; 40; 60; 80; and 100%. The presence of clear zones on Kirby-bauer test, against the growth of each nosocomial bacteria pathogen show that tobacco extract has antibacterial effect. Statistical analysis result showed that each extract concentration had significant difference value (p steroids) of tobacco leaf extracts (N. tabacum) has potential as antibacterial against nosocomial bacteria pathogen. Nevertheless, optimization of tobacco leaf extract to obtain maximum active ingredient still needs to be done. This study is important for further development of the tobacco leaf extract as antibacterial

Nosocomial infections are responsible for a high rate of morbidity and mortality in pediatric patients undergoing heart surgery. Our objective was to determine the incidence and associated risk factors to nosocomial infections in this group of patients. A descriptive, prospective, clinical study was conducted in a tertiary hospital for a year. We calculated the rate of incidence, accumulated incidence and devices used. Was Applied the EPIDAT 2004 version 3.1 program OPS for obtaining of Chi-square with Yates correction for p with a confidence of 95 %, alpha of 0.05 with a degree of freedom, we calculated odds ratio, besides of the identification of microorganisms, their sensitivity and resistance to antibiotics. We calculated rates of: 45 % the incidence, 80.6 % cumulative incidence, 7.4 % of mortality, 13.3 % of case-fatality rate of infected and 2.7 % non-infected. The 44.4 % with pneumonia, 74 % associated with mechanical ventilation, 100 % nasogastric tube. The most frequently isolated microorganisms are: Acinetobacter baumanni, Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa with high resistance to antibiotics. Pediatric patients undergoing heart surgery have high risk of infection heart disease, cyanogen's have 5 times more risk. We observed a statistically significant association with infection using nasogastric probe and endotracheal tube, the risk increases to increased hospital stay. Infected patients have 4 times the risk of death.

Full Text Available To calculate the incremental cost of nosocomial bacteremia caused by the most common organisms, classified by their antimicrobial susceptibility.We selected patients who developed nosocomial bacteremia caused by Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, or Pseudomonas aeruginosa. These microorganisms were analyzed because of their high prevalence and they frequently present multidrug resistance. A control group consisted of patients classified within the same all-patient refined-diagnosis related group without bacteremia. Our hospital has an established cost accounting system (full-costing that uses activity-based criteria to analyze cost distribution. A logistic regression model was fitted to estimate the probability of developing bacteremia for each admission (propensity score and was used for propensity score matching adjustment. Subsequently, the propensity score was included in an econometric model to adjust the incremental cost of patients who developed bacteremia, as well as differences in this cost, depending on whether the microorganism was multidrug-resistant or multidrug-sensitive.A total of 571 admissions with bacteremia matched the inclusion criteria and 82,022 were included in the control group. The mean cost was € 25,891 for admissions with bacteremia and € 6,750 for those without bacteremia. The mean incremental cost was estimated at € 15,151 (CI, € 11,570 to € 18,733. Multidrug-resistant P. aeruginosa bacteremia had the highest mean incremental cost, € 44,709 (CI, € 34,559 to € 54,859. Antimicrobial-susceptible E. coli nosocomial bacteremia had the lowest mean incremental cost, € 10,481 (CI, € 8,752 to € 12,210. Despite their lower cost, episodes of antimicrobial-susceptible E. coli nosocomial bacteremia had a major impact due to their high frequency.Adjustment of hospital cost according to the organism causing bacteremia and antibiotic sensitivity could improve prevention strategies

Full Text Available Background. This prospective cohort study presents the effectiveness and feasibility of a comprehensive control strategy to reduce nosocomial transmission of methicillinresistant Staphylococcus aureus (MRSA in a highly endemic setting.Methods. All patients with MRSA carriage admitted to the University Clinic of Respiratory and Allergic Diseases over a period of 5 years (January 1998 through December 2002 were included and categorized into imported or hospitalacquired cases. In January 1999, an aggressive infection control program was implemented. It was focused on promoting alcohol hand rub, obtaining active surveillance cultures for MRSA, implementing strict barrier precautions and decolonizing MRSA carriers.Results. MRSA was recovered from 223 hospitalized patients; 142 cases were imported and 81 were acquired at our institution. After the introduction of an active surveillance program, the annual incidence of detected MRSA carriage per 1000 admissions first increased from 4.5 in 1998 to 8.0 in 1999 (p = 0.019, but remained stable thereafter. The proportion of patients detected through active surveillance cultures progressively increased from 23% in 1999 to 78% in 2002. Since 1999, the proportion of acquired MRSA cases in our institution has steadily decreased from 50% in 1999 to 6% in 2002 (p < 0.001, whereas the proportion of patients who acquired MRSA in other hospitals (p < 0.001 and nursing homes (p = 0.025 has increased.Conclusions. With a comprehensive infection control program it is possible to substantially reduce nosocomial transmission of MRSA in a highly endemic area. With good hand hygiene, early detection, isolation and decolonization strategy, containment of MRSA is achievable despite a high rate of transferred patients colonized or infected with MRSA from other healthcare facilities.

Enhanced precision of epidemiological typing in clinically suspected nosocomial outbreaks is crucial. Our aim was to investigate whether single nucleotide polymorphism (SNP) analysis and core genome (cg) multilocus sequence typing (MLST) of whole genome sequencing (WGS) data would more reliably identify a nosocomial outbreak, compared to earlier molecular typing methods. Sixteen isolates from a nosocomial outbreak of ESBL E. coli ST-131 in southeastern Sweden and three control strains were subjected to WGS. Sequences were explored by SNP analysis and cgMLST. cgMLST clearly differentiated between the outbreak isolates and the control isolates (>1400 differences). All clinically identified outbreak isolates showed close clustering (≥2 allele differences), except for two isolates (>50 allele differences). These data confirmed that the isolates with >50 differing genes did not belong to the nosocomial outbreak. The number of SNPs within the outbreak was ≤7, whereas the two discrepant isolates had >700 SNPs. Two of the ESBL E. coli ST-131 isolates did not belong to the clinically identified outbreak. Our results illustrate the power of WGS in terms of resolution, which may avoid overestimation of patients belonging to outbreaks as judged from epidemiological data and previously employed molecular methods with lower discriminatory ability. © 2017 APMIS.

La susceptibilidad antibiótica mostró 13 patrones de resistencia; 87% de los aislamientos presentó corresistencia a amikacina, 53% a gentamicina, 33,3% a ciprofloxacina, 40% a cefepime, 66,7% a piperacilina/tazobactam, 60% trimetoprim/sulfametoxazol y 46,7% a cloranfenicol. Todos fueron sensibles a imipenem. En la mayoría de los aislamientos se detectó producción simultánea de beta-lactamasas del tipo TEM y SHV y el 93,3% produjo ceftazidimasa de pI 8.2 del tipo SHV-5. Los 15 aislamientos fueron agrupados por PFGE y REP-PCR en 11 y 12 patrones electroforéticos, respectivamente. Esta variabilidad genética está relacionada con infecciones nosocomiales de origen endógeno más que por infecciones cruzadas.

To determine the impact of antibiotic consumption and alcohol-based hand disinfection on the incidences of nosocomial methicillin-resistant Staphylococcus aureus (MRSA) infection and Clostridium difficile infection (CDI). Two multivariate time-series analyses were performed that used as dependent variables the monthly incidences of nosocomial MRSA infection and CDI at the Freiburg University Medical Center during the period January 2003 through October 2007. The volume of alcohol-based hand rub solution used per month was quantified in liters per 1,000 patient-days. Antibiotic consumption was calculated in terms of the number of defined daily doses per 1,000 patient-days per month. The use of alcohol-based hand rub was found to have a significant impact on the incidence of nosocomial MRSA infection (Phand rub was associated with a lower incidence of nosocomial MRSA infection. Conversely, a higher level of consumption of selected antimicrobial agents was associated with a higher incidence of nosocomial MRSA infection. This analysis showed this relationship was the same for the use of second-generation cephalosporins (P= .023), third-generation cephalosporins (P= .05), fluoroquinolones (P= .01), and lincosamides (P= .05). The multivariate analysis (R2=0.55) showed that a higher level of consumption of third-generation cephalosporins (P= .008), fluoroquinolones (P= .084), and/or macrolides (P= .007) was associated with a higher incidence of CDI. A correlation with use of alcohol-based hand rub was not detected. In 2 multivariate time-series analyses, we were able to show the impact of hand hygiene and antibiotic use on the incidence of nosocomial MRSA infection, but we found no association between hand hygiene and incidence of CDI.

SÍNTESE DOS DADOS: A tecnologia e os novos conhecimentos científicos têm aumentado significantemente a sobrevida de prematuros extremos. Esse aumento da sobrevida resultou em aumento da incidência de displasia broncopulmonar. Atualmente, a displasia broncopulmonar é mais freqüentemente observada em recém-nascidos OBJECTIVE: To review the main causes of new bronchopulmonary dysplasia and the strategies utilized to decrease its incidence in extremely low birth weight infants. DATA SOURCES: For this review a MEDLINE search from 1966 to October 2004, the Cochrane Database, abstracts from the Society for Pediatric Research and recent meetings on the topic were used. SUMMARY OF FINDINGS: The survival of extremely low birth weight infants has increased significantly due to improvement in both scientific knowledge and technology. This improvement in survival has therefore resulted in an increased incidence of bronchopulmonary dysplasia. The characteristics of bronchopulmonary dysplasia in extremely low birth weight infants, the so called "new" bronchopulmonary dysplasia are quite different from the classic bronchopulmonary dysplasia described by Northway. This new bronchopulmonary dysplasia has a multifactorial etiology, which includes volutrauma, atelectrauma, oxygen toxicity and lung inflammation. Therapy such as prenatal corticosteroids, exogenous surfactant, nasal continuous positive airway pressure, new mechanical ventilation modalities and gentle ventilation have been used in attempts to decrease lung injury severity. CONCLUSIONS: In order to prevent lung injury in

The outcome indicator of nosocomial infection (NI) in the intensive care unit (ICU) is used to benchmark the quality of patient care in Malaysia. We conducted a three-year prospective study on the incidences of ventilator-associated pneumonia (VAP), risk factors, and patterns of the microorganisms isolated in three ICUs. A follow-up in prospective cohort surveillance was conducted on patients admitted to an adult medical-surgical ICU of a university hospital and two governmental hospitals in Malaysia from October 2003 to December 2006. VAP was detected using CDC criteria which included clinical manifestation and confirmed endotracheal secretion culture results. In total, 215 patients (2,306 patient-days) were enrolled into the study. The incidence of ICU-acquired device-related NI was 29.3 % (n = 63). The device-related VAP infection rate was 27.0 % (n = 58), with a mechanical ventilator utilization rate of 88.7%. The death rate due to all ICU-acquired NI including sepsis was 6.5%. The most common causative pathogen was Klebsiella pneumoniae (n = 27). Multivariate analysis using Cox regression showed that the risk factors identified were aspiration pneumonia (HR = 4.09; 95% CI = 1.24, 13.51; P = 0.021), cancer (HR = 2.51; 95% CI = 1.27, 4.97; P = 0.008), leucocytosis (HR=3.43; 95% CI= 1.60, 7.37; P=0.002) and duration of mechanical ventilation (HR=1.04; 95% CI = 1.00, 1.08; P = 0.030). Age, gender and race were not identified as risk factors in the multivariable analysis performed. The incidence of VAP was comparable to that found in the National Nosocomial Infection Surveillance (NNIS) System report of June 1998. The incidence of VAP was considered high for the three hospitals studied.

The compliance of hospital staff with guidelines for the active surveillance of methicillin-resistant Staphylococcus aureus (MRSA) in Israel has not been determined. To evaluate the compliance of hospital staff with guidelines for the active surveillance of MRSA and assess its impact on the incidence of nosocomial MRSA bacteremia. We assessed compliance with MRSA surveillance guidelines by assessing adherence to the screening protocol and reviewing medical and nursing charts of patients colonized with MRSA, and observed hand hygiene opportunities among health care workers and colonized patients. Rates of nosocomial MRSA bacteremia and of adherence with hand hygiene among overall hospital staff were obtained from archived data for the period 2001-2010. Only 32.4% of eligible patients were screened for MRSA carriage on admission, and 69.9% of MRSA carriers did not receive any eradication treatment. The mean rate of adherence to glove use among nurses and doctors was 69% and 31% respectively (Phand hygiene 59% and 41% respectively (Phand hygiene increased from 42.3% in 2005 to 68.1% in 2010. Rates of nosocomial MRSA bacteremia decreased by 79.2%, from 0.48 (in 2001) to 0.1 (in 2010) per 1000 admissions (Phand hygiene and concomitant decrease in nosocomial MRSA bacteremia is gratifying. The deficiencies in compliance with MRSA infection control policy warrant an adjusted strategy based on the hospital resources.

Methicillin-resistant Staphylococcus aureus (MRSA) infection has been endemic in the University Hospital, Kuala Lumpur since the late 1970s. Fifty isolates of MRSA obtained from clinical specimens of patients with nosocomial infections associated with this organism have been studied by pulsed-field gel electrophoresis (PFGE) of its chromosomal DNA fragments to discrimate between strains and to identify the predominant strain. Twenty-one chromosomal patterns were observed which could be further grouped into nine types. The predominant strain was Type 9-b (40% of isolates) found mainly in the Orthopaedic and Surgical Units. Outbreak strains found in the Special Care Nursery were of Type 1, entirely different from those of the surgical ward S2, which were of Type 9-b. Type 8 strains were found mainly at one end of the hospital building where the maternity, paediatric and orthopaedic units were situated. Genomic DNA fingerprinting by PFGE is recommended as a useful and effective tool for the purpose of epidemiological studies of MSRA infections, particularly for nosocomial infections.

Ello permite describir sistemáticamente los elementos componentes de los edificios y relevar sus fallas por disciplinas específicas, estableciendo los criterios mínimos de desempeño a considerar en el proyecto, construcción, uso y mantenimiento del hábitat. El partido arquitectónico que no prevea modos de gestión adecuados condiciona negativamente el desempeño de la vivienda social, disminuye sus condiciones de habitabilidad y seguridad y acorta su vida útil. Asimismo, los elevados presupuestos de honorarios y sueldos destinados a la gestión administrativa, en detrimento de las inversiones en mantenimiento correctivo y preventivo, constituyen uno de los motivos que generan deterioro prematuro. La falta de una relación sustentable entre la organización arquitectónica y la organización administrativa atenta contra la eficacia de la gestión, acentuada por ambiguas normas de funcionamiento.

El colectivo de investigadores tuvo que enfrentar una serie de disyuntivas bioéticas que pusieron de manifiesto la integridad de ese colectivo. Se demuestra que los principios de la bioética: beneficiencia, no mal eficiencia, autonomía y justicia, se tuvieron en cuenta en el protocolo de la investigación y durante la ejecución de ésta. Según este análisis, se justifica que se tomara un grupo control histórico, en lugar de un grupo control placebo, para las comparaciones de la utilización del Surfacén y que se optara por el consentimiento parental después de una información verbal por el médico, sin necesidad de utilizar un documento de consentimiento escrito.An analysis was made from the point of view of bioethic principles, on the investigation of a phase III clinical trial regarding the application of Surfacen for the treatment of the respiratory distress syndrome of the newborn in Cuba. The team of investigators had to face a series of bioethic alternatives which evidenced the integrity of the team of workers. It was demonstrated that bioethic principles such as beneficience, efficiency, autonomy, and justice were taken into account to conduct the protocol of the investigation and during the performance of it. According to such analysis, it was justified that a history control group will be taken instead of a placebo control group for the comparison of the utilization of Surfacen.

Acinetobacter baumannii is an emerging pathogen worldwide that is most commonly associated with nosocomial infections and multi-drug resistance. In the present study we determined the mechanisms of carbapenem resistance and clonal diversity of A. baumannii nosocomial isolates in Hospital Civil de Guadalajara, Mexico. A total of 303 clinical isolates of A. baumannii identified during a period expanding from 2004-2011 were analyzed for carbapenem resistance using several microbiological and molecular methods. Clonal relatedness of these isolates was determined using pulsed-field gel electrophoresis. Of the 303 isolates, 84% were resistant to meropenem, 71.3% to imipenem and 78.3% the resistant isolates were positive for metallo-β-lactamases as determined by the phenotypic assay. In addition, 49.6% of carbapenem-intermediate or -resistant isolates carried the blaOXA-72 gene and 1.2% carried the blaVIM-1 gene. Efflux pump phenotype was responsible for reduced susceptibility to meropenem in 14.5% and to imipenem in 31.6% of the resistant isolates, respectively in the presence of the efflux pump inhibitor, carbonyl cyanide 3-chlorophenylhydrazone. Strains representing different carbapenem-resistant patterns exhibited reduced expression of 22, 29, 33, and 43 kDa OMPs. Among the bacterial collection studied, 48 different clones were identified, two of which were predominant and persistently transmitted. Carbapenemase production in combination with efflux pump expression, reduction in OMPs expression and the cross-transmission of clones appear to be major contributors to the high frequency of carbapenem-resistance observed in A. baumannii. To our knowledge, this is the first study to define the molecular mechanisms associated with carbapenem-resistance in A. baumannii in Mexico. Copyright © 2014 IMSS. Published by Elsevier Inc.

Sepsis induces a sustained immune dysfunction responsible for poor outcome and nosocomial infections. Myeloid-derived suppressor cells (MDSCs) described in cancer and inflammatory processes may be involved in sepsis-induced immune suppression, but their clinical impact remains poorly defined. To clarify phenotype, suppressive activity, origin, and clinical impact of MDSCs in patients with sepsis. Peripheral blood transcriptomic analysis was performed on 29 patients with sepsis and 15 healthy donors. A second cohort of 94 consecutive patients with sepsis, 11 severity-matched intensive care patients, and 67 healthy donors was prospectively enrolled for flow cytometry and functional experiments. Genes involved in MDSC suppressive functions, including S100A12, S100A9, MMP8, and ARG1, were up-regulated in the peripheral blood of patients with sepsis. CD14 pos HLA-DR low/neg monocytic (M)-MDSCs were expanded in intensive care unit patients with and without sepsis and CD14 neg CD15 pos low-density granulocytes/granulocytic (G)-MDSCs were more specifically expanded in patients with sepsis (P sepsis. G-MDSCs, made of immature and mature granulocytes expressing high levels of degranulation markers, were specifically responsible for arginase 1 activity. High initial levels of G-MDSCs, arginase 1, and S100A12 but not M-MDSCs were associated with subsequent occurrence of nosocomial infections. M-MDSCs and G-MDSCs strongly contribute to T-cell dysfunction in patients with sepsis. More specifically, G-MDSCs producing arginase 1 are associated with a higher incidence of nosocomial infections and seem to be major actors of sepsis-induced immune suppression.

Full Text Available The events leading to preterm birth are still not completely understood. A quantitative systematic review was performed to estimate the effects of periodontal care during pregnancy on preventing preterm birth and low birth weight. The meta-analysis included randomized trials with pregnant women with a diagnosis of periodontal disease before 20 weeks of gestation. Relative risk (RR with 95% confidence intervals (95%CI was calculated. We evaluated the reduction in preterm and low birth weight. Thirteen trials were included, comparing 3,576 women in intervention groups with 3,412 women receiving usual care. The meta-analysis of the effects of periodontal disease treatment during pregnancy indicated a non-significant reduction in preterm births (RR = 0.90; 95%CI: 0.68-1.19 and low birth weights (RR = 0.92; 95%CI: 0.71-1.20. The creation and examination of a funnel plot revealed clear evidence of publication bias. In summary, primary periodontal care during pregnancy cannot be considered an efficient way of reducing the incidence of preterm birth.Os eventos que levam à prematuridade ainda não são completamente compreendidos.

Full Text Available OBJETIVO: Describir los resultados de diez años de vigilancia de infecciones intrahospitalarias (II en un centro oncológico. MATERIAL Y MÉTODOS: Es un estudio descriptivo, retrospectivo, del programa de vigilancia del Comité de Vigilancia y Control de Infecciones Intrahospitalarias del Instituto Nacional de Cancerología, realizado en 1997. Se utilizaron los criterios de infección intrahospitalaria por sitio propuestos por el Centro para la Prevención y el Control de Enfermedades de Atlanta, Georgia, de Estados Unidos de América, en 1972. De junio de 1986 a diciembre de 1996, se estudiaron 62 733 egresos. La vigilancia se realizó mediante la revisión de los expedientes de pacientes con fiebre, de aquellos que reciben antibióticos y de posoperados en los pisos de hospitalización y revisión de cultivos. Se calcularon las tasas de II por episodios/100 egresos. RESULTADOS: La tasa de infecciones intrahospitalarias por 100 egresos fue de 4.4 en 1986; 7.7, en 1987; 8.1, en 1988; 5.9, en 1989; 4.6, en 1990; 5.1, en 1991; 4.3, en 1992; 5.4, en 1993; 7.6, en 1994; 7.1, en 1995, y 8.5, en 1996.

Nosocomial bloodstream infections are a major cause of morbidity and mortality in neonatal intensive care units. Appropriate hand hygiene is singled out as the most important measure in preventing these infections. However, hand hygiene compliance among healthcare professionals remains low despite the well-known effect on infection reduction. We studied the effectiveness of a hand hygiene education program on the incidence of nosocomial bloodstream infections. Observational study with two pretests and two posttest measurements and interrupted time series analysis. A 27 bed level IIID neonatal intensive care unit in a teaching hospital in the Netherlands. Healthcare professionals who had physical contact with very low birth weight (VLBW) infants. The study was conducted during a period of 4 years. Medical and nursing staff followed a problem-based education program on hand hygiene. Hand hygiene practices before and after the education program were compared by guided observations. The incidence of nosocomial infections in VLBW infants was compared. In addition, numbers of nosocomial bloodstream infections per day-at-risk in very low birth weight infants were analyzed by a segmented loglinear regression analysis. During 1201 observations hand hygiene compliance before patient contact increased from 65% to 88% (pinfections and the infection rate per 1000 patient days (relative risk reduction) before and after the education program on hand hygiene intervention decreased from 44.5% to 36.1% (18.9%, p=0.03) and from 17.3% to 13.5% (22.0%, p=0.03), respectively. At the baseline the nosocomial bloodstream infections per day-at-risk decreased by +0.07% (95% CI -1.41 to +1.60) per month and decreased with -1.25% (95% CI -4.67 to +2.44) after the intervention (p=0.51). The level of instant change was -14.8% (p=0.48). The results are consistent with relevant improvement of hand hygiene practices among healthcare professionals due to an education program.

Full Text Available We report a case of Legionella pneumonia in a 78-year-old patient affected by cerebellar haemangioblastoma continuously hospitalised for 24 days prior to the onset of overt symptoms. According to the established case definition, this woman should have been definitely classified as a nosocomial case (patient spending all of the ten days in hospital before onset of symptoms. Water samples from the oncology ward were negative, notably the patient’s room and the oxygen bubbler, and the revision of the case history induced us to verify possible contamination in water samples collected at home. We found that the clinical strain had identical rep-PCR fingerprint of L. pneumophila serogroup 1 isolated at home. The description of this culture-proven case of Legionnaires’ disease has major clinical, legal, and public health consequences as the complexity of hospitalised patients poses limitations to the rule-of-thumb surveillance definition of nosocomial pneumonia based on 2–10-day incubation period.

This quasi-experimental study aimed to identify the impact of a promotion programme on hand hygiene practices and its effect on nosocomial infection rates in a neonatal intensive care unit of a university hospital in Thailand. The study populations were 26 nursing personnel. After implementing a hand hygiene promotion programme, compliance with hand hygiene among nursing personnel improved significantly from 6.3% before the programme to 81.2% 7 months after the programme. Compliance rate did not correlate with the intensity of patient care. Nosocomial infection rate did not decrease after the intervention, probably because of the multifactorial nature of infections. All participants agreed that promotion programme implemented in this project motivated them to practise better hand hygiene. This study indicated that multiple approaches and persistent encouragement are key factors leading to a sustained high level of appropriate hand hygiene practices among nursing personnel.

2008-06-01

Full Text Available Abstract Background Escherichia coli is the commonest cause of community and nosocomial urinary tract infection (UTI. Antibiotic treatment is usually empirical relying on susceptibility data from local surveillance studies. We therefore set out to determine levels of resistance to 8 commonly used antimicrobial agents amongst all urinary isolates obtained over a 12 month period. Methods Antimicrobial susceptibility to ampicillin, amoxicillin/clavulanate, cefalexin, ciprofloxacin, gentamicin, nitrofurantoin, trimethoprim and cefpodoxime was determined for 11,865 E. coli urinary isolates obtained from community and hospitalised patients in East London. Results Nitrofurantoin was the most active agent (94% susceptible, followed by gentamicin and cefpodoxime. High rates of resistance to ampicillin (55% and trimethoprim (40%, often in combination were observed in both sets of isolates. Although isolates exhibiting resistance to multiple drug classes were rare, resistance to cefpodoxime, indicative of Extended spectrum β-lactamase production, was observed in 5.7% of community and 21.6% of nosocomial isolates. Conclusion With the exception of nitrofurantoin, resistance to agents commonly used as empirical oral treatments for UTI was extremely high. Levels of resistance to trimethoprim and ampicillin render them unsuitable for empirical use. Continued surveillance and investigation of other oral agents for treatment of UTI in the community is required.

Colonization of the ocular conjunctiva in newborns delivered by cesarian section occurs usually within the first day of life. We have studied the flora of the ocular conjunctiva at birth, from 19 newborns delivered by cesarian section, coming from two different maternity hospitals. Ocular conjunctiva cultures yielded the main predominant flora in both maternity hospitals considered. The most common genus of this flora are: Staphylococcus, Corynebacterium and Propionibacterium acnes. Peptostreptococcus productus, Neisseria, Eubacterium and Clostridium perfringens are isolated occasionally. In newborns delivered by cesarian section, this flora principally acquired may be the consequence of the presence of bacteria in the ambient air, as well as differences in care provided by the nosocomial personnel.

The aim of this study is to evaluate what pathogens are mainly responsible for infection among all hospitalised at our ITU patients, to define the influence of antibiotic use on the aetiology of nosocomial infection. The research was conducted on a six-bedded surgical ITU in a 700-bed teaching hospital from January 1995 till June 1996. In August 1995 we changed infection control protocols (more stress on: handwashing with antiseptic soaps and routine microbiological culture for early prediction of infection) and antibiotic guidelines on our ITU (third generation cephalosporins, fluoroquinolones and Vancomycin were used only as the last option and never in prevention). 1276 samples for microbiological culture were obtained in routine manner. From 60% positive cultures 1216 strains were isolated (Tab. 1) and resistance to antibiotics were defined (Tab. 3). Monthly antibiotic consumption was expressed in defined daily dose (DDD) for 1000 hospitalisation-days. DDD = (X/Y)/Z x x 1000, were: X-cumulative antibiotic consumption during analysed period (g), Y-standard daily dose (g/24 h), Z-number of hospitalisation-days during analysed period (Tab. 2). Values were expressed as the mean +/- standard error (SE). Relationships between variables were analysed using linear correlation. All data were categorised for the frequency table. Statistically significant differences were considered to exist when calculated p values were less than 0.05. There were no statistically significant differences in the number of treated patients, length of stay and mortality rate on our ITU in 18 months. 58% of isolated strains were Gram-negative bacteria especially Pseudomonas aeruginosa (22%) and Acinetobacter spp. (16%) and Proteus spp. (9%). The commonly isolated Gram-positive bacteria were Enterococcus faecalis (14%), Staphylococcus aureus (12%)--of which 90% were MRSA. In 8% of cases we have isolated Candida spp. Monthly antibiotic consumption was displayed in table 2. Trend analysis

The burden of nosocomial or health care-associated infection (HCAI) is increasing worldwide. According to the World Health Organization (WHO), it is several fold higher in low- and middle-income countries. Considering the multidrug-resistant infections, the development of new and more effective drugs is crucial. Herein, two series (I and II) of 5-nitrofuran derivatives were designed, synthesized and assayed against microorganisms, including Gram-positive and -negative bacteria, and fungi. The pathogens screened was directly related to either the most currently relevant HCAI, or to multidrug-resistant infection caused by MRSA/VRSA strains, for instance. The sets I and II were composed by substituted-[N'-(5-nitrofuran-2-yl)methylene]benzhydrazide and 3-acetyl-5-(substituted-phenyl)-2-(5-nitro-furan-2-yl)-2,3-dihydro-1,3,4-oxadiazole compounds, respectively. The selection of the substituent groups was based upon physicochemical properties, such as hydrophobicity and electronic effect. The compounds have showed better activity against Staphylococcus aureus, Escherichia coli, and Enterococcus faecalis. The findings from S. aureus strain, which was more susceptible, were used to investigate the intersamples and intervariables relationships by applying chemometric methods. It is noteworthy that the compound 4-butyl-[N'-(5-nitrofuran-2-yl)methylene]benzhydrazide has showed similar MIC value to vancomycin, which is the reference drug for multidrug-resistant S. aureus infections. Taken the findings together, the 5-nitrofuran derivatives might be indeed considered as promising hits to develop novel antimicrobial drugs to fight against nosocomial infection.

We report the epidemiological investigation of a nosocomial pneumonia case due to Legionella pneumophila linked to a contaminated hospital cooling tower in an immune-compromised patient. A 73-year-old female patient was diagnosed with nosocomial Legionella pneumonia proven by a culture of L. pneumophila serogroup 1 from bronchoalveolar lavage fluid. Two strains isolated from the patient and two strains isolated from two cooling towers were found to be identical using repetitive-sequence-based-PCR with a 95% probability. This Legionella pneumonia case might be caused by aerosol from cooling towers on the roof of the hospital building which was contaminated by L. pneumophila. We increased up the temperature of hot water supply appropriately for prevention of Legionella breeding in an environment of patients' living. On the other hand, as the maintenance of cooling tower, we increased the frequency of Legionella culture tests from twice a year to three times a year. In addition, we introduced an automated disinfectants insertion machine and added one antiseptic reagent (BALSTER ST-40 N, Tohzai Chemical Industry Co., Ltd., Kawasaki, Japan) after this Legionella disease, and thereafter, we have no additional cases of Legionella disease or detection of Legionella spp. from the cooling tower or hot water supply. This case demonstrates the importance of detecting the infection source and carrying out environmental maintenance in cooperation with the infection control team.

Full Text Available This study was undertaken to determine the type and estimate the prevalence of bacterial organisms on contact surfaces of five close-to-patient facilities in three veterinary health care settings within the Sokoto metropolis of north-western Nigeria. A total of 30 samples (10 from each setting were collected and analysed using culture, microscopy and biochemical testing. Bacterial species isolated from samples in this study included the following: Bacillus sp. (27.3%, Staphylococcus aureus (15.9%, Listeria sp. (13.6%, Streptococcus sp. (11.4%, Salmonella sp. (6.8%, Escherichia coli (4.5%, Staphylococcus epidermidis (4.5%, Citrobacter sp. (2.3%, Klebsiella sp. (2.3%, Lactobacillus sp. (2.3%, Micrococcus sp. (2.3%, Pasteurella sp. (2.3%, Proteus sp. (2.3%, and Yersinia sp. (2.3%. A higher percentage (64.3% of the total bacterial isolates were zoonotic in nature and hence of public health significance. Some pathogens have the potential of nosocomial spread. In this study, we seek to establish the first evidence of bacterial presence in the major veterinary health care settings in the Sokoto region of north-western Nigeria. Of particular interest is the hypothesis, which has not previously been formally tested, that nosocomial infections are especially likely to be implicated in both animals and occupational diseases in Nigeria. It was suggested that some of these isolates were associated with the risk of nosocomial and zoonotic infections and hence draws attention to the need to rigorously employ standard veterinary precautions as part of the hospital’s infection control programme in an attempt to protect both patients and staff from infections.

As most nosocomial infections are thought to be transmitted by the hands of healthcare workers, handwashing is considered to be the single most important intervention to prevent nosocomial infections. However, studies have shown that handwashing practices are poor, especially among medical personnel. This review gives an overview of handwashing in health care and in the community, including some aspects that have attracted little attention, such as hand drying and cultural issues determining hand hygiene behaviour. Hand hygiene is the most effective measure for interrupting the transmission of micro-organisms which cause infection, both in the community and in the healthcare setting. Using hand hygiene as a sole measure to reduce infection is unlikely to be successful when other factors in infection control, such as environmental hygiene, crowding, staffing levels and education, are inadequate. Hand hygiene must be part of an integrated approach to infection control. Compliance with hand hygiene recommendations is poor worldwide. While the techniques involved in hand hygiene are simple, the complex interdependence of factors that determine hand hygiene behaviour makes the study of hand hygiene complex. It is now recognized that improving compliance with hand hygiene recommendations depends on altering human behaviour. Input from behavioural and social sciences is essential when designing studies to investigate compliance. Interventions to increase compliance with hand hygiene practices must be appropriate for different cultural and social needs.

  To describe the clinical characteristics of pediatric patients colonized or infected by Stenotrophomonas maltophilia (S. maltophilia) at a Saudi children's hospital, to identify risk factors associated with infection, and to investigate the antimicrobial resistance patterns of this emerging pathogen.  Methods: In this cross-sectional observational study, 64 non-duplicating S. maltophilia strains were isolated  in Najran Maternity and Children's Hospital, Najran,  Saudi Arabia between January 2015 to February 2016. Antimicrobial susceptibility testing was performed using the reference broth microdilution method.  Results: In this study, 48 (75%) isolates were identified in true infections and 16 (25%) isolates were considered colonization. The main types of S. maltophilia infection were pneumonia in 22 (45.8%) patients and bloodstream infection in 14 (29.2%) patients. The significant risk factors included exposure to invasive procedure (p=0.02), and presence of acute leukemia as an underlying disease (p=0.02). The most active antimicrobials were trimethoprim/sulfamethoxazole (100% sensitivity) and tigecycline (93.7% sensitivity). Conclusions: Stenotrophomonas maltophilia is an emerging nosocomial pathogen among pediatric patients. Accurate identification and susceptibility testing of this emerging pathogen are crucial for the management of infected patients and prevention of spread of this nosocomial pathogen.

This study analyzed ten strains of coagulase-negative staphylococci (CNS) involved in nosocomial infections in three Brazilian hospitals. Their antibiotic susceptibility profile showed that most strains exhibited multiple antibiotic resistance and possessed the mecA gene. The ability of these strains to adhere to polystyrene microtiter plates was also tested and nine of them proved to be biofilm producers at least in one of the three conditions tested: growth in TSB, in TSB supplemented with NaCl, or in TSB supplemented with glucose. The presence of the bap gene, which codes for the biofilm-associated protein (Bap), was investigated in all ten strains by PCR. AU strains were bop-positive and DNA sequencing experiments confirmed that the fragments amplified were indeed part of a bap gene. The presence of the icaA gene, one of the genes involved in polysaccharide intercellular adhesin (PIA) formation, was also detected by PCR in eight of the ten strains tested. The two icaA-negative strains were either weak biofilm producer or no biofilm producer, although they were bop-positive. To our knowledge, this is the first report demonstrating the presence of the bap gene in nosocomial isolates of CNS, being also the first report on the presence of this gene in Staphylococcus haemolyticus and S. cohnii.

Full Text Available Rinossinusite Nosocomial é uma complicação frequente de pacientes tratados em UTI. É importante o diagnóstico e tratamento precoce para prevenir complicações graves como pneumonia, sepse, meningite e abscesso intracraniano. OBJETIVO: Identificar os agentes causadores de sinusite em UTI através do swab nasal e da punção de seio maxilar, correlacionando seus resultados. MÉTODO: Pacientes atendidos nas unidades de terapia intensiva com diagnóstico tomográfico de sinusopatia maxilar uni ou bilateral foram submetidos ao swab nasal e punção do seio acometido com material enviado para cultura e antibiograma. RESULTADOS: O presente estudo avaliou 22 pacientes. Houve concordância entre o agente microbiano isolado no swab e na punção em 14 dos 22 casos (63%. A flora aeróbia gram negativa foi a mais encontrada com predomínio da Pseudomonas aeruginosa (29% nas punções, seguido de Proteus mirabillis (26% e Acinetobacter baumanni (14%. Houve alto índice de resistência aos antibióticos usados. CONCLUSÃO: A punção direta do seio maxilar acometido em pacientes em UTI com sinusite parece ser o melhor método para identificar os agentes bacterianos e, através do seu antibiograma, direcionar a conduta terapêutica antimicrobiana. O swab mostrou ter pouco valor diagnóstico, com concordância de 63%, podendo ser reservado para casos onde a punção está contraindicada.Nosocomial sinusitis is a common complication of patients in ICUs.

Full Text Available Gelled aspect in papaya fruit is typically confused with premature ripening. This research reports the characterization of this physiological disorder in the pulp of papaya fruit by measuring electrolyte leakage, Pi content, lipid peroxidation, pulp firmness, mineral contents (Ca, Mg and K - in pulp and seed tissues, and histological analysis of pulp tissue. The results showed that the gelled aspect of the papaya fruit pulp is not associated with tissue premature ripening. Data indicate a reduction of the vacuole water intake as the principal cause of the loss of cellular turgor; while the waterlogged aspect of the tissue may be due to water accumulation in the apoplast.O aspecto geleificado da polpa de mamão é constantemente confundido com amadurecimento prematuro. Este trabalho caracterizou esse distúrbio fisiológico na polpa de frutos de mamão através de medidas de liberação de eletrólitos, conteúdo de Pi, peroxidação lipídica, firmeza da polpa, condudo mineral (Ca, Mg e K - na polpa e semente e análises histológicas da polpa. Os resultados mostram que o aspecto geleificado da polpa de mamão não está associado com o amadurecimento prematuro. Os resultados indicam uma redução da entrada de água no vacúolo como a principal causa da perda de turgor celular, enquanto o aspecto encharcado da polpa pode ser devido ao acúmulo de água no apoplasto.

Nosocomial infections remain an important source of morbidity, mortality, and increased health care costs in hospitalized patients. This is particularly problematic in intensive care units (ICUs) because of increased patient vulnerability due to the underlying severity of illness and increased susceptibility from utilization of invasive therapeutic and monitoring devices. Lactoferrin (LF) and the products of its breakdown have multiple biological effects, which make its utilization of interest for the prevention of nosocomial infections in the critically ill. This is a phase II randomized, multicenter, double-blinded trial to determine the effect of LF on antibiotic-free days in mechanically ventilated, critically ill, adult patients in the ICU. Eligible, consenting patients will be randomized to receive either LF or placebo. The treating clinician will remain blinded to allocation during the study; blinding will be maintained by using opaque syringes and containers. The primary outcome will be antibiotic-free days, defined as the number of days alive and free of antibiotics 28 days after randomization. Secondary outcomes will include: antibiotic utilization, adjudicated diagnosis of nosocomial infection (longer than 72 h of admission to ICU), hospital and ICU length of stay, change in organ function after randomization, hospital and 90-day mortality, incidence of tracheal colonization, changes in gastrointestinal permeability, and immune function. Outcomes to inform the conduct of a larger definitive trial will also be evaluated, including feasibility as determined by recruitment rates and protocol adherence. The results from this study are expected to provide insight into a potential novel therapeutic use for LF in critically ill adult patients. Further, analysis of study outcomes will inform a future, large-scale phase III randomized controlled trial powered on clinically important outcomes related to the use of LF.

Full Text Available Background: Nosocomial infections pose substantial risk to patients receiving care in hospitals. In Bangladesh, this problem is aggravated by inadequate infection control due to poor hygiene, resource and structural constraints and lack of awareness regarding nosocomial infections. Objective: We carried out this study to determine the prevalence of different microorganisms from urine in surgery ward and antimicrobial susceptibility pattern against various antibiotics. Materials and Methods: This cross sectional study was carried out in Department of Microbiology, Dhaka Medical College, Dhaka over a period of 12 months from July 2011 to June 2012. A total of 52 urine specimens were collected from catheterized patients admitted in general surgery ward of Dhaka Medical College Hospital (DMCH and incubated in blood agar, MacConkey agar media and the isolates were identified by different biochemical tests – oxidase test and reaction in MIU (motility indole urease and Simmon’s citrate and TSI (triple sugar iron media. ESBL producers were detected by double-disk synergy test (DDST. Results: Bacteria were isolated from 35 specimens and Escherichia coli was the commonest isolate (23, 65.71% followed by Pseudomonas aeruginosa 6 (17.14%, Klebsiella pneumoniae 3 (8.57%, Acinetobacter baumannii 2 (5.72% and Proteus vulgaris 1 (2.86% respectively. Among the isolates, 10 (28.57% ESBL producers were detected and the highest ESBL production was observed in Escherichia coli (8, 22.85% followed by Klebsiella pneumoniae 1 (2.86% and Pseudomonas aeruginosa 1 (2.86%. The isolates were resistant to most of the commonly used antimicrobial agents. Conclusion: The emergence of multi-drug resistant (MDR bacteria poses a difficult task for physicians who have limited therapeutic options. However, the high rate of nosocomial infections and multi-resistant pathogens necessitate urgent comprehensive interventions of infection control.

MÉTODOS: Estudo longitudinal de prematuros OBJECTIVE: To determine chronological and corrected ages at acquisition of motor abilities up to unaided walking in very low weight preterms and to determine up to what point it is necessary to use corrected age. METHODS: This was a longitudinal study of preterms with birth weight < 1,500 g and gestational age < 34 weeks, free from neurosensory sequelae, selected at the high-risk infants follow-up clinic at the Hospital das Clínicas, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (UNESP in Botucatu, Brazil, between 1998 to 2003, and assessed every 2 months until acquisition of unaided walking. RESULTS: Nine percent of the 155 preterms recruited were excluded from the study, leaving a total of 143 patients. The mean gestational age was 30±2 weeks, birth weight was 1,130±222 g, 59% were female and 44% were small for gestational age. Preterms achieved head control in their second month, could sit unaided at 7 months and walked at 12.8 months' corrected age, corresponding to the 4th, 9th and 15th months of chronological age. There were significant differences between chronological age and corrected age for all motor abilities. Preterms who were small for their gestational age acquired motor abilities later, but still within expected limits. CONCLUSIONS: Very low weight preterms, free from neurosensory disorders, acquired their motor abilities within the ranges expected for their corrected ages. Corrected age should be used until unaided walking is achieved.

Methicillin-resistant Staphylococcus aureus (MRSA) nosocomial infections frequently occur in the hospital environment, but their incidence is less often observed in neonates. In the present investigation, seventeen cases were recorded over a nine-week period (two cases per week). Pulsed field gradient gel electrophoresis confirmed the clonal character of the strain. The hypothesis of manually-transmitted infection due to contamination from multiple sources was reinforced by the fact the epidemic persisted in spite of the elimination of the main human infectious source and an absence of risk factors determined by the case-control study. The role of environmental factors in the persistence of this outbreak of MRSA infection has been considered.

During prospective epidemiological surveillance cases of pyogenic and septic infections (PSI) in mothers and newborns in two maternity hospitals were studied using standard case definition and leading risk factors of their development were revealed. These factors differed in two hospitals and were connected mainly with high level of patients colonization, contamination of the environment by nosocomial strains of microorganisms, and degree of participation of mother's relatives in delivery. It was shown that permission to relatives for presence on delivery did not influence on the rate of PSI. Specificity of risk factors of PSI in mothers and newborns dictates necessity to determine them in each maternity hospital.

Preterm neonates are susceptible to infection due to a combination of sub-optimal immunity and increased exposure to invasive organisms. Invasive fungal infections are associated with significant morbidity and mortality among preterm infants cared for in the neonatal intensive care unit (NICU). Mannose-binding lectin (MBL) is a component of the innate immune system, which may be especially important in the neonatal setting. The objective of this study was to investigate the presence of any association between MBL gene polymorphism and nosocomial invasive fungal infection in preterm neonates. Codon 54 (B allele) polymorphism in exon 1 of the MBL gene was investigated in 31 patients diagnosed as nosocomial invasive fungal infection and 30 control preterm neonates. AB genotype was determined in 26% and 30% of patient and control groups, respectively, and the difference was not statistically significant. AA genotype was determined in 74% of the patient group and in 67% of the control group, and the difference was not statistically significant. B allele frequency was not different significantly in the patient group (13%) compared to the control group (18%). In our study, no relationship was found between MBL codon 54 gene polymorphism and the risk of nosocomial invasive fungal infection in preterm neonates in NICU.

To investigate different Musa sp. leave extracts of hexane, ethyl acetate and methanol were evaluated for antibacterial activity against multi-drug resistant pathogens causing nosocomial infection by agar well diffusion method and also antioxidant activities. The four different Musa species leaves were extracted with hexane, ethyl acetate and methanol. Antibacterial susceptibility test, minimum inhibitory concentration and minimum inhibitory bacterial concentration were determined by agar well diffusion method. Total phenolic content and in vitro antioxidant activity was determined. All the Musa sp. extracts showed moderate antibacterial activities expect Musa paradisiaca with the inhibition zone ranging from 8.0 to 18.6 mm. Among four species ethyl acetate extracts of Musa paradisiaca showed highest activity against tested pathogens particularly E. coli, P. aeruginosa and Citrobacter sp. The minimum inhibitory concentrations were within the value of 15.63- 250 µg/mL and minimum bactericidal concentrations were ranging from 31.25- 250 µg/mL. Antioxidant activity of Musa acuminate exhibited maximum activity among other three Musa species. The present study concluded that among the different Musa species, Musa paradisiaca displayed efficient antibacterial activity followed by Musa acuminata against multi-drug resistant nosocomial infection causing pathogens. Further, an extensive study is needed to identify the bioactive compounds, mode of action and toxic effect in vivo of Musa sp.

To study the transmission route of severe acute respiratory syndrome (SARS) nosocomial infection. Ten identified SARS patients were selected from a general hospital in March. Survey was carried out through a standardized questionnaire provided by Chinese Center for Disease Control and Prevention. Contents of the questionnaire would include: history of contact with SARS patient, route of infection, methods used for protection and so on. (1) Distribution os SARS patients were confined to 3 wards: 4, 5, and 6 on the 7, 8, 12, 13 and 14 floors in the west unit of the inpatient building. Most of the inpatients were elderly and having severe original diseases. (2) Index patients were the first generation source of transmission and they infected inpatients and medical staff, making them the second generation. People with latent infection who had close contact with SARS patients might also serve as the possible source of transmission. (3) The major transmission routes were: near distant droplet infection and close contact infection. There was also a clue to the probability of aerosol or droplet nuclei infection through air-conditioning and ventilation system. Nosocomial infection appeared to be the main characteristic of the SARS epidemic in the early stage of this hospital. Other than close contact and near space airborne transmission of SARS virus, the possibility of long-distance aerosol transmission called for further epidemiological and experimental studies in the future.

C. difficile is recognised as the main cause for colitis in hospitalised patients which are treated with antibiotics, chemotherapics or other drugs that disturb intestinal microbiota. Thus, a rapid and correct diagnostic of Clostridium difficile infections is essential for preventing nosocomial infection spread. Empiric therapy, regardless of the laboratory investigation results, is inadequate, especially in epidemic situations, as not all the cases of diarrhoea are due to C. difficile infection. Other risk factors for CDAD (Clostridiumn difficile Associated Diseases might be: prolonged hospitalization or residency in an asylum, age, existence of a severe chronic disease in the background nasogastric intubation, anti-ulcer drugs, at less extent gastrointestinal surgery, other immunosuppresive compounds etc. In our country, C. difficile infection is rather frequent in adults, though it is not always reported by clinicians. The circulation of endemic rybotype 027 in Romania is not well documented, the rybotype being extremely virulent and spread in other European countries. Hence the importance of extending the diagnostic capacity of C. difficile infection in order to allow detection of this rybotype among the strains isolated in our country.

Pseudomonas aeruginosa represents a serious clinical challenge due to its frequent involvement in nosocomial infections and its tendency towards multidrug resistance. This study uncovered antibiotic susceptibility patterns in 177 isolates from inpatients in three key hospitals in Aleppo, the largest city in Syria. Exceptionally low susceptibility to most routinely used antibiotics was uncovered; resistance to ciprofloxacin and gentamicin was 64.9% and 70.3%, respectively. Contrarily, susceptibility to colistin was the highest (89.1%). Multidrug resistance was rife, found at a rate of 53.67% among studied P. aeruginosa isolates.

Full Text Available Introduction: Nosocomial Infections (NI are a frequent and relevant problem, in other hands; those are responsible of mortality especially in pediatric ICU( Intensive Care Unit and NICUs (Neonatal Intensive Care Unit. Healthcare-associated infections are important in wide-ranging concern in the medical field. The most cause of Nosocomial infection include: bloodstream infection, urinary tract infection, pneumonia, and wound infection. The purpose of this study was to determine the epidemiology of the three most common NI in the Pediatric department.        Materials and Methods: We performed a prospective study in a single Pediatric department during 12 months. Children were assessed for 3 NI: wound infections, pneumonia and urinary tract infections (UTI, as the same method as Center of Disease Control criteria. All patients were followed up and individuals who had have NI and their treatment was entered in this study.          Results: In this study 811 patients were hospitalized that 60% of them were male and were older than 60 months. The main causes of hospitalization include: toxicity, seizure, respiratory infection and fever. Among them 15 cases had NI (1.87%. The most NI occurred in pediatric intensive care unit (PICU and it was followed in aspect of intubation. The most cultured organism was pseudomonas that they suspected to ceftazidime and isolate from blood and endotracheal tube.           Conclusion:  NI presence was associated with increased mortality and length of stay in hospital. This study highlights the importance of NIs in children admitted to a pediatric department especially PICU in a developing country. Clinical monitoring of NIs and bacterial resistance profiles are required in all pediatric units.

Background Recent evidence suggests that less than one-quarter of patients with symptomatic nosocomial Clostridium difficile infections (CDI) are linked to other in-patients. However, this evidence was limited to one geographic area. We aimed to investigate the level of symptomatic CDI transmission in hospitals located across England from 2008 to 2012. Methods A generalized additive mixed-effects Poisson model was fitted to English hospital-surveillance data. After adjusting for seasonal fluctuations and between-hospital variation in reported CDI over time, possible clustering (transmission between symptomatic in-patients) of CDI cases was identified. We hypothesised that a temporal proximity would be reflected in the degree of correlation between in-hospital CDI cases per week. This correlation was modelled through a latent autoregressive structure of order 1 (AR(1)). Findings Forty-six hospitals (33 general, seven specialist, and six teaching hospitals) located in all English regions met our criteria. In total, 12,717 CDI cases were identified; seventy-five per cent of these occurred >48 hours after admission. There were slight increases in reports during winter months. We found a low, but statistically significant, correlation between successive weekly CDI case incidences (phi = 0.029, 95%CI: 0.009–0.049). This correlation was five times stronger in a subgroup analysis restricted to teaching hospitals (phi = 0.104, 95%CI: 0.048–0.159). Conclusions The results suggest that symptomatic patient-to-patient transmission has been a source of CDI-acquisition in English hospitals in recent years, and that this might be a more important transmission route in teaching hospitals. Nonetheless, the weak correlation indicates that, in line with recent evidence, symptomatic cases might not be the primary source of nosocomial CDI in England. PMID:24932484

Hospital-acquired Clostridium difficile infection is associated with adverse patient outcomes and high medical costs. The incidence and severity of C. difficile has been rising in both medical and surgical patients. Our aim was to assess risk factors and variation associated with the development of nosocomial C. difficile colitis among patients undergoing colorectal resection. This was a retrospective cohort study. The study included segmental colectomy and proctectomy cases in New York State from 2005 to 2013. The study cohort included 150,878 colorectal resections. Patients with a documented previous history of C. difficile infection or residence outside of New York State were excluded. A diagnosis of C. difficile colitis either during the index hospital stay or on readmission within 30 days was the main measure. C. difficile colitis occurred in 3323 patients (2.2%). Unadjusted C. difficile colitis rates ranged from 0% to 11.3% among surgeons and 0% to 6.8% among hospitals. After controlling for patient, surgeon, and hospital characteristics using mixed-effects multivariable analysis, significant unexplained variation in C. difficile rates remained present across hospitals but not surgeons. Patient factors explained only 24% of the total hospital-level variation, and known surgeon and hospital-level characteristics explained an additional 8% of the total hospital-level variation. Therefore, ≈70% of the hospital variation in C. difficile infection rates remained unexplained by captured patient, surgeon, and hospital factors. Furthermore, there was an ≈5-fold difference in adjusted C. difficile rates across hospitals. A limited set of hospital and surgeon characteristics was available. Colorectal surgery patients appear to be at high risk for C. difficile infection, and alarming variation in nosocomial C. difficile infection rates currently exists among hospitals after colorectal resection. Given the high morbidity and cost associated with C. difficile colitis

Tienen un patrón de herencia autosómico recesivo, excepto para la enfermedad de Fabry y la enfermedad de Hunter en las que el patrón de herencia está ligado al cromosoma X. Estas enfermedades tienen una baja incidencia en general, aunque hay poblaciones donde algunas de ellas tienen una alta incidencia. Su importancia radica en la magnitud que representan como problema de salud, por la pobre calidad de vida de esos pacientes, así como su fallecimiento prematuro, motivo por el cual hay que evitar los nacimientos de nuevos niños afectados.Among the metabolism inborn errors, there are the lysosomal storage diseases or lysosomal enzymopathies that are characterized by an specific enzymatic deficiency, excretion of metabollites in urine and accumulation of non-degraded compounds in various organs and tissues causing their dysfunction. These diseases have a recessive autosomal heredity, except for Fabry´s disease and Hunter’s disease in which the pattern of heredity is chromosome X-linked. These diseases have a low incidence in general although there are populations where they show a high incidence. Their importance lies in what they represent as a health problem because of the poor quality of life of these patients and their early death, therefore, it is necessary to prevent the birth of new infants affected with these diseases.

The aim of this study was to evaluate the efficacy of skin cleansing with chlorhexidine (CHD) in the prevention of neonatal nosocomial sepsis - a randomized controlled trial. This study design was a randomized controlled trial carried out in a tertiary care center of north India. About 140 eligible neonates were randomly allocated to either the subject area group (wiped with CHD solution till day seven of life) or the control group (wiped with lukewarm water). The primary outcome studied was to determine the decrease in the incidence of neonatal nosocomial sepsis (blood culture proven) in the intervention group. Out of 140 enrolled neonates, 70 were allocated to each group. The ratio of positive blood culture among the CHD group was 3.57%, while the ratio of positive blood culture among the control group was 6.85%. There was trending towards a reduction in blood culture proven sepsis in the intervention group, although the remainder was not statistically significant. A similar decreasing trend was observed in rates of skin colonization, duration of hospital stay, and duration of antibiotic treatment. CHD skin cleansing decreases the incidence of blood culture sepsis and could be an easy and cheap intervention for reducing the neonatal sepsis in countries where the neonatal mortality rate is high because of sepsis.

Full Text Available Orthopedic patients mostly comprise traumatic patients and elderly or sick individuals. More patients with emergency surgery suffer from open wounds and serious pollution, and operation time is relatively long. Thus, orthopedic patients with surgical incision infection account for a large proportion of incidence of hospital infection. Orthopedic patients are also bedridden for long periods, and they receive poor bone tissue blood supply. In surgical incision infections, mild cases suffer from delayed wound healing, whereas severe cases can form osteomyelitis. This study reviews progress of research on risk factors of nosocomial infection among orthopedic patients in recent years.

Nosocomial sinusitis is a common complication of patients in ICUs. Its diagnosis is important, and early treatment is required to avoid serious complications such as pneumonia, sepsis, meningitis, and intracranial abscesses. To identify the germs causing sinusitis in ICUs by nasal swabs and maxillary sinus puncture, and to correlate these results. ICU patients with a diagnosis (CT confirmed) of maxillary sinusitis underwent nasal swab and puncture of the sinus to collect material for culture and antibiogram. This study evaluated 22 patients. The microbial agent isolated in the swab correlated with the agent in the puncture in 14 of 22 cases (63%). Gram-negative bacteria were the most frequent, as follows: Pseudomonas aeruginosa (29% of punctures), following by Proteus mirabillis (26%) and Acinetobacter baumanni (14%). The resistance index in the antibiogram was high to antibiotics. Maxillary sinus puncture of ICU patients with sinusitis appears to be the best method for identifying bacteria; antibiograms demonstrate resistance to therapy. The swab has little diagnostic value; the correlation was 63%. It may be used when sinus puncture is contraindicated.

Nosocomial infections have long been neglected in Sub-Saharan Africa, even though their prevalence is higher than in developed countries. Recently, however, this major public health problem has been the focus of a growing number of recommendations not only from the World Health Organization but also from some national health ministries. Because of the numerous limitations especially in financial resources in these regions, priority must be given to the implementation of simple and cost-effective measures. Accordingly the greatest efforts must be devoted to educating healthcare workers and patients about the importance of handwashing, eliminating unnecessary injections and transfusions, performing the latter acts in aseptic conditions, isolating patients with communicable diseases, handling waste products safely, and using antimicrobials properly. Amid the daunting health issues facing Sub-Saharan Africa, implementing these inexpensive measures that could save the lives of thousands of patients and healthcare workers appears easy. However it will require a cultural revolution. The keys to success will be changing the organizational culture, developing a commitment to prevention and evaluating performance regularly.

The study describes a proactive infection control approach to prevent nosocomial transmission of vancomycin-resistant enterococci (VRE) and tests if this approach is effective for controlling multiple-drug resistant organisms in a nonendemic setting. In response to the increasing prevalence of VRE in Hong Kong since 2011, we adopted a multifaceted assertive approach in our health care network. This included active surveillance culture, extensive contact tracing, directly observed hand hygiene in conscious patients before they received meals and medications, stringent hand hygiene and environmental cleanliness, and an immediate feedback antimicrobial stewardship program. We report the occurrence of VRE outbreaks in our hospital after institution of these measures and compared with the concurrent occurrence in other public hospitals in Hong Kong. Between July 1, 2011 and November 13, 2013, VRE was identified in 0.32% (50/15,851) of admission episodes by active surveillance culture. The risk of VRE carriage was three times higher in patients with a history of hospitalization outside our hospital networks in the past 3 months (0.56% vs. 0.17%; p = 0.001) compared with those who were not. Extensive contact tracing involving 3277 patient episodes was performed in the investigation for the 25 VRE index patients upon whom implementation of contact precautions was delayed (more than 48 hours of hospitalization). One episode of VRE outbreak was identified in our hospital network, compared with the 77 VRE outbreaks reported in the other hospital networks (controls) without these proactive infection control measures. Our multifaceted assertive proactive infection control approach can minimize the nosocomial transmission and outbreak of VRE in a nonendemic area. Copyright © 2014. Published by Elsevier B.V.

To present the epidemiology of the outbreak and the description of patients with infection or colonization of the respiratory tract caused by A. baumannii in an Internal Medicine ward. 20 consecutively patients hospitalized in the Internal Medicine ward were studied during 18 months with isolation of multiresistant A. baumanni in respiratory tract specimens with or without clinical signs of infection. Starting on an index case, that was a patient coming from other hospital with diagnosis of nosocomial Acinetobacter pneumonia, we detected 20 patients. The age of the patients ranged from 48 to 95 years, with a mean of 71.4 years. Eighty percent were males. The clinical features were similar: advanced age, with chronic diseases (35 percent diabetics, 45 percent with chronic lung diseases), and use of broad-spectrum antibiotics agents, fundamentally third generation cephalosporin (70 percent), clarithromycin (55 percent) and quinolones (30 percent). 75 percent of patients were in the same ward. Eight (40 percent) of the patients with chronic lung diseases were subjects with COPD, two with asthma and chronic glucocorticoids treatment, and one with a sleep apnea. In four cases the isolation was considered a colonization. The mean stay was 26.15 days, and the mortality 40 percent. The nosocomial infection caused by Acinetobacter baumannii is responsible of a high morbi-mortality between the patients hospitalized in an Internal Medicine ward, and produce an increase in length of stay. It is necessary a combination of control measures to prevent the transmission in the hospital and the outbreak of new multiresistant strains.

Objective To determine risk factors for multi-drug-resistant Acinetobacter baumannii (MDR-AB) nosocomial infections in intensive care units in a tertiary care hospital, Makkah, Saudi Arabia. Methods We performed a hospital-based, matched case–control study in patients who were admitted to Al Noor Specialist Hospital between 1 January 2012 and 31 August 2012. The study included cases of A. baumannii nosocomial infection and controls without infection. Controls were matched to cases by age and ward of admission. Results The most frequent site of infection was the respiratory tract (77.3%). Susceptibility to antimicrobial MDR-AB was 92.0% for ceftazidime and ciprofloxacin, while it was 83.3% for imipenem, 83.0% for trimethoprim, 79.0% for amikacin, and 72.7% for gentamicin. Multiple logistic regression of risk factors showed that immunosuppression (OR = 2.9; 95% CI 1.5–5.6; p = 0.002), clinical outcome (OR = 0.4; 95% CI 0.3–0.9; p = 0.01), invasive procedures (OR = 7.9; 95% CI 1.8–34.2; p = 0.002), a central venous catheter (OR = 2.9; 95% CI 1.5–5.6; p = 0.000), and an endotracheal tube (OR = 3.4; 95% CI 1.6–7.3; p = 0.001) were associated with MDR-AB. Conclusions Acinetobacter nosocomial infections are associated with admission to the ICU (Intensive care unit) and exposure to invasive procedures. PMID:28480813

Full Text Available Controversy exists as to whether obesity constitutes a risk-factor or a protective-factor for the development of nosocomial Infection (NI. According to the obesity-paradox, there is evidence that moderate obesity is a protective-factor. In Mexico few studies have focused on the nutritional status (NS distribution in the hospital setting.The aim of this study was to estimate the distribution of NS and the prevalence of nosocomial infection NI among adult elective surgery (ES patients and to compare the clinical and anthropometric characteristics and length of stays (LOS between obese and non-obese patients and between patients with and without NI.We conducted a cross-sectional study with a sample (n = 82 adult ES patients (21-59 years old who were recruited from a tertiary-care hospital. The prevalences of each NS category and NI were estimated, the assessments were compared between groups (Mann-Whitney, Chi-squared or the Fisher's-exact-test, and the association between preoperative risk-factors and NI was evaluated using odds ratios.The distribution of subjects by NS category was: underweight (3.66%, normal-weight (28.05%, overweight (35.36%, and obese (32.93%. The prevalence of NI was 14.63%. The LOS was longer (p<0.001 for the patients who developed NI. The percentages of NI were: 33.3% in underweight, 18.52% in obese, 17.39% in normal-weight, and 6.90% in overweight patients.The prevalence of overweight and obesity in adult ES patients is high. The highest prevalence of NI occurred in the underweight and obese patients. The presence of NI considerably increased the LOS, resulting in higher medical care costs.

Increasingly, policy reform in health care is discussed in terms of changing organizational culture, creating practice teams, and organizational quality management. Yet, the evidence for these suggested determinants of high-quality care is inconsistent. To determine if the type of organizational culture (Competing Values Framework), team climate (Team Climate Inventory), and preventive pressure ulcer quality management at ward level were related to the prevalence of pressure ulcers. Also, we wanted to determine if the type of organizational culture, team climate, or the institutional quality management related to preventive quality management at the ward level. In this cross-sectional observational study multivariate (logistic) regression analyses were performed, adjusting for potential confounders and institution-level clustering. Data from 1274 patients and 460 health care professionals in 37 general hospital wards and 67 nursing home wards in the Netherlands were analyzed. The main outcome measures were nosocomial pressure ulcers in patients at risk for pressure ulcers (Braden score ≤ 18) and preventive quality management at ward level. No associations were found between organizational culture, team climate, or preventive quality management at the ward level and the prevalence of nosocomial pressure ulcers. Institutional quality management was positively correlated with preventive quality management at ward level (adj. β 0.32; p organizational culture, team climate, or preventive quality management at the ward level. These results would therefore not subscribe the widely suggested importance of these factors in improving health care. However, different designs and research methods (that go beyond the cross-sectional design) may be more informative in studying relations between such complex factors and outcomes in a more meaningful way.

Full Text Available Objective. To determine the prevalence and microbiological behavior of the infections in hospitalized patients in the burn unit of the University Hospital San José ( HUSJ at Popayan, Colombia, 2010-2011. Methods: A retrospective cross-sectional study was conducted in patients admitted to the burn unit of HUSJ between the years 2010–2011. Patients were characterized sociodemographic and clinically. The prevalence of nosocomial infections was estimated. Frequency and antibiotic resistance of microorganisms isolated was described. Data were analyzed using SPSS version 15. Results. 113 patients was enrolled, the average age was 17.7 years and male gender predominated (55.8%. Hot liquids (64.6% were the principal cause, the average of body surface area burned was 11.3% and the average hospital stay was 19.8 days. 13.3% of the patients had some nosocomial infection. The most frequently diagnosed infections were sepsis (24%, urinary tract infection (20% and pneumonia (20%. Staphylococcus aureus was the most frequent bacteria (41.7% followed by Staphylococcus epidermidis, mostly meticilino-resistant. The mean length of hospital stay and burned surface area (BSA in patients with diagnosis of infection was 36.6 days and 17.3% respectively. Conclusions. The prevalence of infection is similar to that reported in Colombia. The resistance of the isolates was high. The meticilinoresistance of Staphylococcus was associated with clindamicina resistance.

Full Text Available Aims: Nosocomial infection is associated with increased mortality, morbidity, and length of stay. Detection of infection, identify the etiology of bacterial antibiotic resistance pattern, is necessary given the widespread use of antibiotics and antibiotic-resistant organisms. Materials and Methods: This cross-sectional study was done on 288 patients admitted to the Beheshti Hospitals in Kashan based on NNIS definitions according to the state of Health and Medical education. In this study infections and antibiotic resistance symptoms were found. Data analyses were performed with Chi-square test. Results: Among the 288 patients studied, with mean out of hospital infection was 0.80%. Most cases of infection associated were pneumonia. The highest rates of infection were in the Intensive Care Unit (ICU with 51.7%. Nosocomial infection in ICU wards was associated with increased mortality and morbidity. The most common types were ventilator-associated pneumonia. Among the microorganisms, negative Gram was seen more. The common pathogens were including Acinetobacter, Escherichia coli, and Klebsiella. Antimicrobial resistance was generally increasing and had emerged from selective pressure from antibiotic use and transmission through health staff. Conclusion: This study showed a correlation between antibiotic use and resistance of microorganisms is significant. Hence, it seems that reducing aggressive acts and conduct hygiene education and monitoring act of antibiotics is necessary to prevent antibiotic resistance.

Ultraviolet radiation (UV) is commonly used to destroy microorganisms in the health-care environment. However, the efficacy of UV radiation against bacteria growing within biofilms has never been studied. To measure the sterilization effectiveness of UV radiation against common healthcare associated pathogens growing within biofilms. Staphylococcus aureus, Methicillin-resistant S. aureus (MRSA), Streptococcus epidermidis, Escherichia coli, ESBL-producing E. coli, Pseudomonas aeruginosa and Acinetobacter baumannii were cultivated in the Calgary Biofilm Device. Their biofilms were placed 50 cm from the UV lamp within the Biosafety Cabinet. Viability test, crystal violet assay and a scanning electron microscope were used to evaluate the germicidal efficacy. Within 5 minutes, UV radiation could kill S. aureus, MRSA, S. epidermidis, A. baumannii and ESBL-producing E. coli completely while it required 20 minutes and 30 minutes respectively to kill E. coli and P. aeruginosa. However, the amounts of biomass and the ultrastructure between UV-exposed biofilms and controls were not significantly different. UV radiation is effective in inactivating nosocomial pathogens grown within biofilms, but not removing biofilms and EPS. The biofilm of P. aeruginosa was the most durable.

Background  Nosocomial infection remains the most common complication of hospitalisation. Despite infection control efforts, nosocomial methicillin resistant Staphylococcus aureus (MRSA) transmission continues to rise. Various isolation practices are used to minimise MRSA transmission in acute care. However, the effectiveness of these practices has seldom been evaluated. Objectives  This review sought to evaluate the efficacy of isolation practices in minimising MRSA transmission in the acute hospital setting and explore staff, visitor and patient compliance with isolation practices. This review updates a review published in 2002. Search strategy  A systematic search for relevant published or unpublished English language literature was undertaken using electronic databases, the reference lists of retrieved papers and the Internet. This extended the search published in the original review. Databases searched included: Medline, CINAHL, EMBASE, Cochrane Library and Joanna Briggs Institute Evidence Library. Selection criteria  All English language research reports published between 1990 and August 2005 that focused on the role of isolation practices on the nosocomial transmission of MRSA in adult, paediatric or neonatal acute care settings were eligible for inclusion in the review. Studies that evaluated multiple infection control strategies or control of MRSA outbreaks were excluded. The main outcome of interest was the incidence of new cases of MRSA. The secondary outcome was staff, visitor and patient compliance with the isolation practices. Data collection and analysis  Two reviewers assessed each paper against the inclusion criteria and a validated quality scale. Data extraction was undertaken using a tool designed specifically for this review. Statistical comparisons of findings were not possible, so findings are presented in a narrative form. Results  Seven studies met the inclusion criteria. Given the small number of included studies and variable

An obvious color change to brown color and surface plasmon resonance by UV-visible spectroscopy (UV-vis) indicated a well observable peak at 440 nm confirming the synthesis of AgNPs. Fourier transform infra-red spectroscopy (FTIR) analysis indicates protein as possible capping agents. Energy dispersive X-ray (EDAX) spectroscopy results showed major signal for elemental silver. X-ray diffraction (XRD) analysis indicates the formation of metallic silver nanomaterials. Transmission electron microscopic (TEM) study showed the nanoparticles in the size range of 18-21 nm with spherical shape. Zeta potential analysis showed -21.7 mV characteristic for stable AgNPs. The biosynthesized AgNPs exhibited significant antimicrobial activity against MDR-GNB nosocomial pathogens of Acinetobacter sp., Klebsiella pneumoniae and Pseudomonas aeruginosa. Results from the current study suggested that M. scabrella material could be exploited for the fabrication of AgNPs with potential therapeutic applications in nanomedicine especially for nosocomial bacterial infections.

Recognition and Prevention of Nosocomial Malnutrition: A Review and A Call to Action!

Kirkland, Lisa L; Shaughnessy, Erin

2017-12-01

Nosocomial malnutrition in hospitalized adults is a morbid, costly, and potentially preventable and treatable problem. Although recognized as contributing to many serious complications of hospitalization, malnutrition is often missed when present on admission and rarely diagnosed if it occurs during hospital stay. Many routine clinical practices such as holding nutrition for testing or failing to address poor intake, when added to acute inflammatory disease states, cause rapid deterioration in nutritional status in up to 70% of inpatients. Malnutrition during hospitalization is associated with increased mortality for years after discharge. In addition, unrecognized (and under-coded) malnutrition is associated with potential lost revenues for hospital systems. Low-cost interventions of recognizing at-risk patients and providing adequate nutrition have the potential to improve patient outcomes and reduce health care costs. Physicians must champion implementation of these interventions, using guidance from national organizations. Copyright © 2017 Elsevier Inc. All rights reserved.

[Analysis of the factors influencing the internal reporting of nosocomial infections. A review of 108 notifications].

Since July 26, 2001, the external reporting to the regional office of health and social affairs (Direction départementale des affaires sanitaires et sociales--Ddass) and the coordination centre (Comité de lutte contre les infections nosocomiales--Cclin) for the fight against nosocomial infections (NI) is mandatory. However, the modalities of internal reporting to the Clin are unknown. We performed a retrospective analysis of 108 cases of NI reported over 23 months in 4 medical-surgical departments (MSD) with 14 to 35 NI reported/MSD. The distribution of the bacteria responsible was compared with that of the local epidemiological state (chi2 test). A correlation analysis was performed between the number of NI reported in each MSD and the structural characteristics and activity index of these MSD (Spearmann's correlation test). The NI were predominantly infections related to a catheter (43), lower respiratory tract (25) and infection of the site of surgery (19). Ninety were documented biologically, among which 10 implied multi-resistant bacteria. Ninety-four NI were associated with the prescription of an antibiotic. Compared with the local epidemiological state, the NI reported generally implied multi-resistant bacteria (p=0.009). The other microbiological data had little implication. In each of the MSD, the number of cases reported was independent of: the global activity, the number of interventions, the mean duration of hospitalisation, the number of beds, the number of clinicians, the number of new patients managed and the chemotherapy outpatient activity. Conversely, there was a strong correlation between the global consumption of antibiotics (r=0.78), and the number of the Clin members in each MSD DMC (r=0.82). In each MSD, the internal reporting of NI relies on the discovery of multi-resistant bacteria, but above all on the implication of those involved in the fight against nosocomial infections.

Prevention of nosocomial infection in the ICU setting.

Corona, A; Raimondi, F

The aim of this review is to focus the epidemiology and preventing measures of nosocomial infections that affect the critically ill patients. Most of them (over 80%) are related to the device utilization needed for patient life support but responsible for such complications as ventilator-associated pneumonia (VAP), catheter-related bloodstream infections (CRBSI), surgical site infections (SSI) and urinary tract infections (UTI). General recommendations include staff education and use of a surveillance program with a restrictive antibiotic policy. Adequate time must be allowed for hand washing and barrier precautions must always be used during device manipulation. The routine changing of central catheters is not necessary and increases costs; it is necessary to decrease the handling of administration sets, to use a more careful insertion technique and less frequent set replacement. Specific measures for VAP prevention are: 1). use of multi-use, closed-system suction catheters; 2). no routine change of the breathing circuit; 3). lubrication of the the endotracheal tube cuff with a water-soluble gel; 4). maintenance of patient in semi-recumbent position to improve chest physiotherapy. Specific measures for UTI prevention include: 1). use of a catheter-valve instead of a standard drainage system; 2). use of a silver-alloy, hydro gel-coated latex urinary catheter instead of uncoated catheters. By implementing effective preventive measures and maintaining strict surveillance of ICU infections, we hope to affect the associated morbidity, mortality, and cost that our patients and society bare. More clinical trials are needed to verify the efficacy of prevention measures of ICU infections.

Measures to control tuberculous infection are crucial to prevent nosocomial transmission and protect health care workers (HCWs). In Portugal, the extent of implementation of tuberculosis (TB) control measures in hospitals is not known. To determine the current implementation of preventive measures for tuberculous infection at administrative, environmental and personal levels in Portuguese hospitals. A cross-sectional evaluation was performed using two anonymous questionnaires: one sent to all the hospital infection control (IC) committees and the other sent to all pulmonologists and physicians specialising in infectious disease. Fourteen IC committees and 72 physicians responded. According to the IC committees, 92% of hospitals had a written TB control plan, but only 37% of the physicians said there was always/almost always a fast track for diagnosing suspected pulmonary TB cases. The majority of the hospitals had an isolation policy (85%) and these patients were always/almost always admitted in separate rooms, according to 70% of physicians. Both HCWs and TB patients used respiratory protection equipment (92%). These findings indicate that the most basic TB IC measures had been undertaken, but some TB IC measures were not fully implemented at all hospitals. An institutional effort should be made to solve this problem and strengthen TB prevention activities.

A cada niño, al momento del nacimiento, se le tomaron mediciones antropométricas seleccionadas. Estas mediciones sirvieron para establecer la condición nutricional del neonato, según las curvas de crecimiento intrauterino adoptadas en la institución. La encuesta de Metcoff se aplicó antes de la obtención de las mediciones antropométricas. La serie de estudio se dividió en dos grupos iguales de hembras y varones. El 97,2 % de los neonatos tenía entre 29 y 36 semanas de gestación en el momento del nacimiento. El 40,0 % de los pacientes examinados presentaba afectación simultánea de la longitud supina y del peso. Solo la circunferencia cefálica se incrementó a medida que avanzó la edad gestacional. Según el puntaje de Metcoff, el 81,4 % de los neonatos tenían estigmas de desnutrición extrauterina. La sensibilidad de la encuesta de Metcoff fue igual o mayor del 90,0 % cuando se comparó con otros indicadores del estado nutricional del recién nacido, aunque a costa de una especificidad menor del 50,0 %. La baja especificidad de la encuesta de Metcoff sugiere que es posible reconocer signos de depleción tisular en niños pretérminos que muestran tasas de crecimiento intrauterino preservadas.The functional features of Metcoff´s survey are presented after being used in the assessment of the nutritional status of 70 babies that were born before the 37th week of gestation, in “Ramón González Coro” Gyneco-obstetric Hospital, from June 2003 to January 2005.

Studies on incidence and prevention of nosocomial infection of urinary tract endoscopies by different antimicrobial agents

Nosocomial infections occur world wide and affect both developed and resource-poor countries. Infections acquired in health care settings are among the major causes of death and increased morbidity among hospitalized patients. They are a significant burden both for the patient and for public health. A prevalence survey conducted under the auspices of WHO in 55 hospitals of 14 countries representing 4 WHO Regions (Europe, Eastern Mediterranean, South-East Asia and Western Pacific) showed an average of 8.7% of hospital patients had nosocomial infections. At any time, over 1.4 million people worldwide suffer from infectious complications acquired in hospital (Tikhomirov , 1987 ) . In medical practice, an object should be disinfected or sterilized depending on its intended use. Items that come in direct contact with mucous membranes, such as endoscopes, require a high level of disinfection (Ayliffe et al., 2000) . The major problems leading to inadequate decontamination are inappropriate or incomplete decontamination methods, for example, choice of disinfectant and duration of contact, as well as use of water or other fluids of poor microbiological quality for decontamination (Fallis , 1994 ). Endoscopes had been used widely for the diagnosis and therapy of medical disorders and were used increasingly for performing laparoscopic surgery. Currently, greater than 10,000,000 gastrointestinal endoscopic procedures were performed each year. Endoscopes were contaminated routinely by microorganisms during clinical use. Failure to employ appropriate cleaning, disinfection, or sterilization of endoscopes have been responsible for multiple nosocomial outbreaks and serious, sometimes life-threatening infections (Spach et al ., 1993 ). Because the endoscope comes into intimate contact with mucous membranes, high-level disinfection was the current reprocessing standard after each patient use. High level disinfection refered to the use of a chemical sterilant at shorter exposure

We experienced Hepatitis A, B, C and fulminant hepatitis due to Herpes simplex virus type 1 (HSV-1) in our hospital for the severely multi-disabled (SMD) who had both severe motor and intellectual disabilities, and some of whom might be further complicated by blindness and/or deafness. In this hospital, 100 SMDs are hospitalized. Case 1: The disabled, 25 year old male, was transmitted Hepatitis A from a nurse. Case 2: The disabled, 60 year old female carrier of Hepatitis B virus (HBV) who has been cared for more than 10 years. Case 3: The disabled, 46 year old male carrier of Hepatitis C virus (HCV) (RNA type 3), has been cared for more than 4 years. Case 4: The disabled, 39 year old male, had a fever of 39 degrees C for 9 days and suddenly died. He was diagnosed as fulminant hepatitis due to HSV-1 by necropsy. The hospitals for SMD are characteristic in prevention of nosocomial infections; 1) The disabled infected is not aware of the fact that he or she is the source of infection and that the other disabled living with him or her are in risk of infection, because of their severe mental condition. 2) All of the disabled need complete or incomplete helps for activities of daily life (ADL), so that the disabled who is the carrier of some pathogen constantly gives risk of infection to staffs, including medical staffs (doctor, nurse and therapist), psychologist and helpers by bloody secretion from wounds, saliva, urine, feces as well as menstrual blood. 3) If a carrier of some pathogen is hospitalized, the staffs should serve under risk of infection involving blood-mediated infectious disease for many years, because SMDs are permitted lifelong stay in the hospitals for SMD, which also play a role of care house or institution, by public expense in Japan. In case of an outbreak of Hepatitis A, nosocomial infection ended in the original case (a nurse), another nurse and a case of the disabled by general treatment and care against communicable diseases of the digestive

To identify independent risk factors for endometritis and urinary tract infection (UTI) after vaginal delivery, and to monitor changes in nosocomial infection rates and derive benchmarks for prevention. Prospective study. We analyzed routine surveillance data for all vaginal deliveries between January 1997 and December 2003 at 66 maternity units participating in the Mater Sud-Est surveillance network. Adjusted odds ratios for risk of endometritis or UTI were obtained using a logistic regression model. The overall incidence rates were 0.5% for endometritis and 0.3% for UTI. There was a significant decrease in the incidence and risk of endometritis but not of UTI during the 7-year period. Significant risk factors for endometritis were fever during labor, parity of 1, and instrumental delivery and/or manual removal of the placenta. Significant risk factors for UTI were urinary infection on admission, premature rupture of membranes (more than 12 hours before admission), blood loss of more than 800 mL, parity of 1, instrumental delivery, and receipt of more than 5 vaginal digital examinations. Each maternity unit received a poster showing graphs of the number of expected and observed cases of UTI and endometritis associated with vaginal deliveries, which enabled each maternity unit to determine their rank within the network and to initiate prevention programs. Although routine surveillance means additional work for maternity units, our results demonstrate the usefulness of regular targeted monitoring of risk factors and of the most common nosocomial infections in obstetrics. Most of the information needed for monitoring is already present in the patients' records.

The early detection of a methicillin-resistant Staphylococcus aureus (MRSA) outbreak is decisive to control its spread and rapidly initiate adequate infection control measures. Therefore, prompt determination of epidemiologic relatedness of clinical MRSA isolates is essential. Genetic typing methods have a high discriminatory power but their availability remains restricted. In this study, we aimed to challenge matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) as a typing tool of a nosocomial MRSA outbreak in a neonatal intensive care unit. Over a 2-year period, 15 MRSA isolates were recovered from patients (n = 14) and health care workers (n = 1) at the neonatal intensive care unit. Five reference strains were included for comparison. Identification was performed by MALDI-TOF MS and susceptibility profiles determined by automated broth microdilution. Typing analysis by MALDI-TOF MS included mean spectrum profiles and subsequent dendrogram creation using BioNumerics software. Results were compared with spa typing and pulsed-field gel electrophoresis (PFGE). Our study showed good concordance (93%) between PFGE, spa typing, and MALDI-TOF MS for the outbreak-related MRSA strains. MALDI-TOF MS typing showed excellent typeability and discriminatory power but showed poor reproducibility. This study is one of the first to document the potential usefulness of MALDI-TOF MS with standardized data analysis as a typing tool for investigating a nosocomial MRSA outbreak. A concordance of 93% compared to reference typing techniques was observed. However, because of poor reproducibility, long-term follow-up of prospective isolated strains is not practical for routine use. Further studies are needed to confirm our observations.

Full Text Available Todos los años nacen en el mundo alrededor de 13 millones de niños prematuros. La mayor parte de esos niños nacen en países en desarrollo y constituyen el componente principal de la morbilidad y la mortalidad perinatales. En el presente estudio de revisión se analizaron los datos científicamente validados sobre las intervenciones que se emplean con la intención de evitar al menos una parte de los partos pretérmino y disminuir su impacto en la salud neonatal. Se consultaron las bases de datos Biblioteca Cochrane y Medline y se estudiaron 50 trabajos de revisión y artículos de investigación relacionados con el tema del parto pretérmino en sus siguientes aspectos: factores de riesgo y detección precoz del riesgo de parto pretérmino; prevención de la amenaza de parto pretérmino; tratamiento del parto pretérmino iniciado, y prevención del síndrome de dificultad respiratoria neonatal. Se encontraron pocos medios ensayados con éxito para predecir, prevenir o detectar precozmente la amenaza de parto pretérmino. Solo el tamizaje y tratamiento de la bacteriuria asintomática pueden recomendarse para todas las embarazadas como parte del control prenatal. El tamizaje de la vaginosis bacteriana y su tratamiento ulterior y el cerclaje profiláctico reducen, respectivamente, la incidencia de nacimientos adelantados en embarazadas con antecedentes de parto prematuro y en las que tienen antecedentes de más de tres partos pretérmino. Como tratamiento del parto iniciado antes de tiempo, con o sin rotura prematura de membranas, las intervenciones que han mostrado eficacia son la administración de betamiméticos a la parturienta para prolongar por 48 horas el período de latencia del parto y de indometacina con el mismo objetivo como medicamento de segunda elección.

Full Text Available Introduction: Enteric bacteria causing nosocomial infections are often resistant to third-generation cephalosporins due to the production of extended-spectrum β-lactamases (ESBLs. Objective: To describe and characterize the ESBLs pattern present in Klebsiella pneumoniae and Serratia marcescens strains, isolated as causative of nosocomial sepsis in pediatric patients at Instituto Nacional de Pediatría (National Institute of Pediatrics. Material and methods: We analyzed 94 strains of K. pneumoniae and 7 of S. marcescens isolated from clinical specimens from 2002-2005, causative of sepsis in a children’s hospital. We evaluated antibiotic susceptibility and detection of ESBL phenotypes by disk diffusion methods; ceftazidime-resistant isolates were further characterized by pulsed field gel electrophoresis (PFGE; and ESBLs were phenotypically and genotypically characterized by isoelectric focusing, polymerase chain reaction (PCR and sequencing. We also assed for presence of conjugative plasmids bearing the ESBL gene. Results: 51/94 (54% of K. pneumoniae isolates, and 5/7 (71% of S. marcescens isolates were resistant to ceftazidime; all carried a blaSHV-5 gene. All K. pneumoniae isolates had a distinct PFGE profile, yet all carried a ~48-Kb plasmid, that was conjugatively transferable to an Escherichia coli receptor, which expressed the resistance phenotype. On the other hand, all S. marcescens isolates had a similar PFGE profile, were unable to transfer the ceftazidime-resistance phenotype, and were isolated from the same ward in a short time-span suggesting an outbreak. Conclusions: The overall prevalence of ESBL-producing enteric bacteria in this hospital is high but similar to other Latin American reports. The sulfhydryl variable-5 (SHV-5 ESBL gene appears to reside in a highly mobile plasmid, capable of spreading among different K. pneumoniae clones and perhaps even to S. marcescens.

In some countries, a relationship between hospital ownership and the occurrence of healthcare-associated infection (HCAI) rates has been described. To investigate the association between hospital ownership and occurrence of HCAI in Germany. Five different components of the German national nosocomial infection surveillance system were analysed with regard to the influence of hospital ownership in the period 2014-2016. Endpoints included ventilator-associated pneumonia, central-venous-catheter-associated bloodstream infections, urinary-catheter-associated urinary tract infections, surgical site infections (SSI) following hip prosthesis and colon surgery, meticillin-resistant Staphylococcus aureus (MRSA), Clostridium difficile infections (CDI) and hand rub consumption per 1000 patient-days. Three hospital ownership types (public, non-profit and private) were analysed using univariate and multi-variate methods. The distribution of hospitals according to the three ownership types was similar in all components. In total, 661 intensive care units (ICUs), 149 departments performing colon procedures, and 349 departments performing hip prosthesis were included. In addition, 568 hospitals provided their MRSA rates and 236 provided their CDI rates, and 1833 ICUs and 12,934 non-ICUs provided their hand rub consumption data. In general, the differences between the hospital types were rather small and not significant for the ICUs. In the multi-variate analysis, public hospitals had a lower SSI rate following hip prosthesis (odds ratio 0.80, 95% confidence interval 0.65-0.99). Hospital ownership was not found to have a major influence on the incidence of HCAI in Germany. Copyright © 2018 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

Global burden of hospital-associated infection (HAI) is on the rise and contributes significantly to morbidity and mortality of the patients. Mobile phones are indispensible part of communication among doctors and other health care workers (HCWs) in hospitals. Hands of HCWs play an important role in transmission of HAI and mobile phones which are seldom cleaned and often touched during or after the examination of patients without hand washing can act as a reservoir for transmission of potent pathogens. This study aimed to investigate the rate of bacterial contamination of mobile phones among HCWs in our tertiary care hospital and to compare it with personal mobile phones of non-HCWs (control group). The mobile phones and dominant hands of 386 participants were sampled from four different groups, hospital doctors and staff (132), college faculty and staff (54), medical students (100) and control group (100). Informed consent and questionnaire was duly signed by all the participants. Samples were processed according to standard guidelines. 316 mobile phones (81.8%) and 309 hand swab samples (80%) showed growth of bacterial pathogens. The most predominant isolates were Coagulase-negative Staphylococcus, Staphylococcus aureus, Acinetobacter species, Escherichia coli, Klebsiella pneumoniae, Pseudomonas species and Enterococcus species. Hundred percent contamination was found in mobile phones and hands of HCWs indicating mobile phones can be the potential source of nosocomial pathogens. Our study results suggest that use of mobile phones in health care setup should be restricted only for emergency calls. Strict adherence to infection control policies such as proper hand hygiene practices should be followed.

Nosocomial outbreaks of parvovirus B19 (pB19) have been reported, but they rarely occur among healthcare personnel (HCP). Susceptibility among pregnant HCP was the major concern. An outbreak of pB19 among HCP is described in a paediatric ward with a cross-sectional serologic study in all HCP and patients exposed to the outbreak. Acute infection was diagnosed by polymerase chain reaction or positive anti-parvovirus B19 IgM. Among 48 HCP (three pregnant) and 22 patients included in the outbreak serologic study, 11 (23%) HCP and two (9%) patients had acute infection. Of these, six HCP and no patients were symptomatic. Clinical manifestations included itchy rash (100%) and joint pain following resolution of rash (67%), with median rash duration of four days. Forty percent of HCP and 50% of patients had positive anti-parvovirus IgG, indicating previously immune status. HCP with acute infection and HCP who were susceptible without infection were younger than HCP with previous immunity (mean age 32.2 vs 40.5 years, respectively; P = 0.003). The attack rate was 38% among HCP and 18% among patients who were susceptible, respectively. The outbreak ended within two weeks following strict droplet precaution and segregation of symptomatic HCP. Parvovirus B19 infection may cause nosocomial outbreak with high attack rate among HCP. Outbreak control with droplet precaution was highly effective. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

The Immune Response against Acinetobacter baumannii, an Emerging Pathogen in Nosocomial Infections

Acinetobacter baumannii is the etiologic agent of a wide range of nosocomial infections, including pneumonia, bacteremia, and skin infections. Over the last 45 years, an alarming increase in the antibiotic resistance of this opportunistic microorganism has been reported, a situation that hinders effective treatments. In order to develop effective therapies against A. baumannii it is crucial to understand the basis of host–bacterium interactions, especially those concerning the immune response of the host. Different innate immune cells such as monocytes, macrophages, dendritic cells, and natural killer cells have been identified as important effectors in the defense against A. baumannii; among them, neutrophils represent a key immune cell indispensable for the control of the infection. Several immune strategies to combat A. baumannii have been identified such as recognition of the bacteria by immune cells through pattern recognition receptors, specifically toll-like receptors, which trigger bactericidal mechanisms including oxidative burst and cytokine and chemokine production to amplify the immune response against the pathogen. However, a complete picture of the protective immune strategies activated by this bacteria and its potential therapeutic use remains to be determined and explored. PMID:28446911

To determine the role of nonmedicated soap as a source of Serratia marcescens nosocomial infections (NIs) in hospital units with endemic S marcescens NI and to examine the mechanisms of soap colonization. University-affiliated tertiary-care hospitals. A prospective case-control study and an environmental investigation were performed to assess the relationship between S marcescens NIs in hospital units and S marcescens-contaminated soap. Soap-bottle use and handwashing practices were reviewed. Cultures of healthcare workers' (HCWs) hands were obtained before and after hand washing with soap. 5 of 7 hospital units with S marcescens NIs had soap bottles contaminated with S marcescens, compared to 1 of 14 other units (P=.006). After hand washing with an S marcescens-contaminated soap pump, HCWs' hands were 54 times more likely to be contaminated with S marcescens (Pliquid soap by S marcescens resulted in handborne transmission of S marcescens NIs by HCWs in our setting. This finding led to the application of strict guidelines for nonmedicated soap use and to the reinforcement of alcoholic hand disinfection.

Aim: To assess the role of ultrasound equipment as a possible source of nosocomial infection in Lagos metropolis, Nigeria. Methods: Microbiological cultures were carried out on samples obtained from ultrasound probes, gel and couch before and after scanning period. Cultures were incubated in a culture plate (Chocolate and MacConkey agar) for 48 h at a temperature of 37 ° in order to grow microorganism, after which the culture plate was examined microscopically against a bright light in order to identify the isolated organisms based on their colonial characteristics. Results: Transabdominal ultrasound probes, transvaginal probe, ultrasound couch and ultrasound gel all were contaminated with microorganisms. Staphylococcus aureus was the most frequent and most common organisms found (33.8%). Other organisms such as Staphylococcus epidermidis (15.4%), Candida albicans (6.2%), aerobic spore formers (26.2%), Klebsiella pneumonia (6.2%), Pseudomonas aeruginosa (3.1%), among others were also identified. Conclusion: The ultrasound equipment posed a significant risk for infection transmission. Patients who underwent ultrasonography within the period of the study had significant chances of being infected with Staphylococcus aureus, S. epidermidis and Aerobic spore formers. - Highlights: • Ultrasound equipment has been shown to be a possible source of nosocomial infection for patient undergoing ultrasonography. • The study showed that Staphylococcus aureus was the most commonly isolated organism. • Transabdominal probe was the most commonly contaminated ultrasound equipment in the finding. • The ultrasound gel was also contaminated with organisms like S. aureus, etc. • There was a statistical significant difference between site of collection of sample and growth density of microorganisms (p = 0.03)
