Monitoring procalcitonin in febrile neutropenia: what is its utility for initial diagnosis of infection and reassessment in persistent Fever?

Background: Management of febrile neutropenic episodes (FE) is challenged by lacking microbiological and clinical documentation of infection. We aimed at evaluating the utility of monitoring blood procalcitonin (PCT) in FE for initial diagnosis of infection and reassessment in persistent fever.Methods: PCT kinetics was prospectively monitored in 194 consecutive FE (1771 blood samples): 65 microbiologically documented infections (MDI, 33.5%; 49 due to non-coagulase-negative staphylococci, non-CNS), 68 clinically documented infections (CDI, 35%; 39 deep-seated), and 61 fever of unexplained origin (FUO, 31.5%).Results: At fever onset median PCT was 190 pg/mL (range 30-26'800), without significant difference among MDI, CDI and FUO. PCT peak occurred on day 2 after onset of fever: non-CNS-MDI/deep-seated-CDI (656, 80-86350) vs. FUO (205, 33-771; p<0.001). PCT >500 pg/mL distinguished non-CNS-MDI/deep-seated-CDI from FUO with 56% sensitivity and 90% specificity. PCT was >500 pg/ml in only 10% of FUO (688, 570-771). A PCT peak >500 pg/mL (1196, 524-11950) occurred beyond 3 days of persistent fever in 17/21 (81%) invasive fungal diseases (IFD). This late PCT peak identified IFD with 81% sensitivity and 57% specificity and preceded diagnosis according to EORTC-MSG criteria in 41% of cases. In IFD responding to therapy, median days to PCT <500 pg/mL and defervescence were 5 (1-23) vs. 10 (3-22; p = 0.026), respectively.Conclusion: While procalcitonin is not useful for diagnosis of infection at onset of neutropenic fever, it may help to distinguish a minority of potentially severe infections among FUOs on day 2 after onset of fever. In persistent fever monitoring procalcitonin contributes to early diagnosis and follow-up of invasive mycoses

Characteristics and quality of care of diabetic patients residing int the canton of Vaud

Introduction: Within the framework of the «Programme cantonal Diabète», we aimed at collecting data to 1) describe the population of diabetic patients in the canton of Vaud, and 2) assess the quality of their care. Methods: A cross-sectional study was conducted in the fall of 2011. Out of 140 randomly selected community pharmacies registered in the canton of Vaud, 56 accepted to participate in patients' recruitment. Noninstitutionalized adult diabetic patients (disease duration >12 months) visiting a pharmacy with a prescription for oral anti-diabetic drugs, insulin, glycemic strips or glucose meter were eligible. Patients not residing in the canton of Vaud, not speaking and understanding French well enough, presenting obvious cognitive impairment, and women with gestational diabetes, were excluded. Using a self-administered questionnaire, data was collected on patients' characteristics and diabetes as well as various process (e.g. recommended annual screenings) and outcomes quality of care indicators. Descriptive analyses were performed. Results: A total of 406 patients with diabetes participated. Mean age was 64 years, 41% were women and 63% were married. Patients reported type 1, 2 and other types of diabetes in 13%, 69% and 19%, respectively. They were treated with oral anti-diabetic drugs, insulin or both in 50%, 23% and 27% of the cases. Half of the patients did not report any diabetes-related complication. Glucose self-monitoring was reported by 82% of the patients. Of those who were aware of HbA1C (n = 218), 98% reported at least one HbA1C control during the last 12 months. During that same time frame, 97% and 95% reported at least one blood pressure and weight measure, 94% reported having had a cholesterol check, 74%, 68% and 64% had eyes, feet and urine screening respectively. 62% of the patients had been immunized against influenza. At least 76% of the patients had a minimum of 5 of the 7 described process indicators performed during the last 12 months. Among patients who knew the value (n = 145), mean HbA1C was 7.4 (SD 1.2). Conclusion: This study targeting community-based diabetic patients shows that while routine clinical and laboratory tests were annually performed in the vast majority of patients, feet and urine screening, as well as influenza immunization, were less often reported by patients. The proportion of patients with diabetes having had at least 5 out of the 7 annual screenings performed was nevertheless very high.

Teaching the measurement of blood pressure for both nursing and public health nursing students The purpose of this two-phase study was to develop the teaching of blood pressure measurement within the nursing degree programmes of the Universities of Applied Sciences. The first survey phase described what and how blood pressure measurement was taught within nursing degree programmes. The second intervention phase (2004-2005) evaluated first academic year nursing and public health nursing students’ knowledge and skills results for blood pressure measurement. Additionally, the effect on the Taitoviikko experimental group students’ blood pressure measurement knowledge and skills level. A further objective was to construct models for an instrument (RRmittTest) to evaluate nursing students measurement of blood pressure (2003-2009). The research data for the survey phase were collected from teachers (total sampling, N=107, response rate 77%) using a specially developed RRmittopetus-questionnaire. Quasi-experimental study data on the RRmittTest-instrument was collected from students (purposive sampling, experimental group, n=29, control group, n=44). The RRmittTest consisted of a test of knowledge (Tietotesti) and simulation-based test (TaitoSimkäsi and Taitovideo) of skills. Measurements were made immediately after the teaching and in clinical practice. Statistical methods were used to analyse the results and responses to open-ended questions were organised and classified. Due to the small amount of materials involved and the results of distribution tests of the variables, non-parametric analytic methods were mainly used. Experimental group and control group similar knowledge and skills teaching was based on the results of the national survey phase (RRmittopetus) questionnaire results. Experimental group teaching includes the supervised Taitoviikko teaching method. During Taitoviikko students studied blood pressure measurement at the municipal hospital in a real nursing environment, guided by a teacher and a clinical nursing professional. In order to evaluate both learning and teaching the processes and components of blood pressure measurement were clearly defined as follows: the reliability of measurement instruments, activities preceding blood pressure measurement, technical execution of the measurement, recording, lifestyle guidance and measurement at home (self-monitoring). According to the survey study, blood pressure measurement is most often taught at Universities of Applied Sciences, separately, as knowledge (teaching of theory, 2 hours) and skills (classroom practice, 4 hours). The teaching was implemented largely in a classroom and was based mainly on a textbook. In the intervention phase the students had good knowledge of blood pressure measurement. However, their blood pressure measurement skills were deficient and the control group students, in particular, were highly deficient. Following in clinical practice the experimental group and control group students’ blood pressure measurement recording knowledge improve and experimental groups declined lifestyle guidance. Skills did not improve within any of the components analysed. The control groups` skills on the whole, declined statistically.There was a significant decline amongst the experimental group although only in one component measured. The results describe the learning results for first academic year students and no parallel conclusions should be drawn when considering any learning results for graduating students. The results support the use and further development of the Taitoviiko teaching method. The RRmittTest developed for the study should be assessed and the results seen from a negative perspective. This evaluation tool needs to be developed and retested.

A real-time measurement system for long-life flood monitoring and warning applications

A flood warning system incorporates telemetered rainfall and flow/water level data measured at various locations in the catchment area. Real-time accurate data collection is required for this use, and sensor networks improve the system capabilities. However, existing sensor nodes struggle to satisfy the hydrological requirements in terms of autonomy, sensor hardware compatibility, reliability and long-range communication. We describe the design and development of a real-time measurement system for flood monitoring, and its deployment in a flash-flood prone 650 km2 semiarid watershed in Southern Spain. A developed low-power and long-range communication device, so-called DatalogV1, provides automatic data gathering and reliable transmission. DatalogV1 incorporates self-monitoring for adapting measurement schedules for consumption management and to capture events of interest. Two tests are used to assess the success of the development. The results show an autonomous and robust monitoring system for long-term collection of water level data in many sparse locations during flood events.

A multicentre randomized controlled trial of an empowerment-inspired intervention for adolescents starting continuous subcutaneous insulin infusion : a study protocol

Background. Continuous subcutaneous insulin infusion (CSII) treatment among children with type 1 diabetes is increasing in Sweden. However, studies evaluating glycaemic control in children using CSII show inconsistent results. Omitting bolus insulin doses using CSII may cause reduced glycaemic control among adolescents. The distribution of responsibility for diabetes self-management between children and parents is often unclear and needs clarification. There is much published support for continued parental involvement and shared diabetes management during adolescence. Guided Self-Determination (GSD) is an empowerment-based, person-centred, reflection and problem solving method intended to guide the patient to become self-sufficient and develop life skills for managing difficulties in diabetes self-management. This method has been adapted for adolescents and parents as Guided Self-Determination-Young (GSD-Y). This study aims to evaluate the effect of an intervention with GSD-Y in groups of adolescents starting on insulin pumps and their parents on diabetes-related family conflicts, perceived health and quality of life (QoL), and metabolic control. Here, we describe the protocol and plans for study enrolment. Methods. This study is designed as a randomized, controlled, prospective, multicentre study. Eighty patients between 12-18 years of age who are planning to start CSII will be included. All adolescents and their parents will receive standard insulin pump training. The education intervention will be conducted when CSII is to be started and at four appointments in the first 4 months after starting CSII. The primary outcome is haemoglobin A1c levels. Secondary outcomes are perceived health and QoL, frequency of blood glucose self-monitoring and bolus doses, and usage of carbohydrate counting. The following instruments will be used to evaluate perceived health and QoL: Disabkids, 'Check your health', the Diabetes Family Conflict Scale and the Swedish Diabetes Empowerment Scale. Outcomes will be evaluated within and between groups by comparing data at baseline, and at 6 and 12 months after starting treatment. Results and discussion. In this study, we will assess the effect of starting an insulin pump together with the model of Guided Self-Determination to determine whether this approach leads to retention of improved glycaemic control, QoL, responsibility distribution and reduced diabetes-related conflicts in the family. Trial registration: Current controlled trials: ISRCTN22444034

Adesão ao tratamento por pacientes portadores de diabetes tipo 1 e tipo 2: efeitos do treino de discriminação de dicas internas e externas

O presente trabalho pretende comparar resultados de treinos de discriminação de sintomas e de ações relativas ao tratamento do diabetes Tipo 1 e Tipo 2, avaliando a eficácia desses treinos para a estimativa do índice glicêmico e para a promoção de adesão ao tratamento. Inúmeras pesquisas realizadas na área de psicologia da saúde têm o objetivo de proporcionar a melhora no tratamento ao paciente diabético. Parte dessas pesquisas utiliza um procedimento denominado de- automonitoração, a qual consiste em habilidades de observação, aferição e registro de aspectos relevantes no tratamento do diabetes. como: (a) índice glicêmico (IG) (b) sintomas (dicas internas -DI); e (c) ações envolvidas no tratamento nas áreas da medicação, alimentação e atividade física (dicas externas -DE). Estudos têm demonstrado que com a automonitoração o paciente diabético melhora o nível de discriminação das alterações glicêmicas. Essa.literatura não é clara em definir qual o melhor tipo de dica para melhorar a discriminação dos estados glicêmicos e afirm que o desenvolvimento desta habilidade não favorece a melhora na adesão ao tratamento. Esse estudo compreendeu três fases: (a) Entrevista inicial e de linha de Base; (b ) Entrevistas de Treino e (c) Entrevista Final e Devolutiva. A fase de treino está dividida em duas etapas Dicas Internas (DI) e Dicas Externas (DE). Nas etapas de treino os participantes estimaram e atribuíram causa para taxa de glicose sangüínea medida por um reflectômetro em cada entrevista. Na etapa DE. os participantes também recebiam feedback do pesquisador acerca do relato de seguimento das orientações, com base nas orientações recebidas em consulta e compiladas do prontuário do paciente. Foi calculado o índice de adesão (IA) nas duas primeiras fases. As entrevistas da fase de treino foram realizadas na residência do participante, em intervalos de três dias, nos quais o participante registrava a ocorrência de eventos correspondentes a etapa que estava realizando. Os resultados demonstram que independente do tipo de treino realizado os participantes estimaram os seus estados glicêmicos com base em dicas externas. Os sintomas' relatados na etapa DI nem sempre estavam associados ao Ia medido. Os participantes portadores de diabetes. Tipo 1 alcançaram maior precisão nas estimativas no treino de DE. A maioria dos participantes alcançaram melhor adesão quando iniciaram o treino por DE. Os resultados sugerem que: (a) relatos de sintomas não são os melhores indicadores para avaliar o estado glicêmico e a adesão ao tratamento (b) o melhor tipo de treino para promoção da adesão ao tratamento é o que envolve as dicas externas.

Percepções de portadores de diabetes sobre a doença: contribuições da Enfermagem

Este estudo objetivou descrever a percepção dos usuários sobre a diabetes. A pesquisa foi descritiva e exploratória, com abordagem qualitativa; o cenário foi um hospital na cidade de Belém-PA, com participação de 32 sujeitos. Empregando-se a técnica de análise de conteúdo temática, emergiram quatro categorias: Controle do diabetes: a enfermagem na automonitorização da glicemia; O diabético e a enfermagem: uma interação para o autocuidado; Consulta de enfermagem ao diabético: a intervenção no processo saúde-doença; Diabetes e suas complicações: o medo repercutido na perda de funções. Observou-se que o paciente começa a se cuidar impulsionado pelo medo de perder sua saúde, obrigando-o ao autocuidado. O enfermeiro está diretamente ligado com o controle da diabetes, a partir do momento que realiza os cuidados e orientações da automonitorização da doença.

Prática da utilização de lancetas ou agulhas na automonitorização da glicemia capilar no domicílio

Estudo descritivo transversal que teve como objetivo conhecer o comportamento de pessoas com diabetes mellitus em relação à prática de utilização das lancetas e/ou agulhas na automonitorização da glicemia capilar no domicílio. O estudo foi realizado em uma Unidade Básica de Saúde no município de Ribeirão Preto-SP, de agosto de 2008 até julho de 2009. Os dados foram obtidos através de entrevista dirigida, com 57 sujeitos. Os resultados mostraram que 41 (71,9%) pessoas reutilizavam as lancetas e/ou agulhas, na frequência de 1 a 5 vezes (52,6%). Todos os sujeitos referiram que não compartilham a mesma lanceta e/ou agulha com outras pessoas. Torna-se necessário incrementar estudos futuros para investigar os riscos e benefícios dessa prática, como também cursos de capacitação em educação em diabetes para os profissionais de saúde, visando atender à complexidade do cuidado dos usuários.

A educação em saúde no cuidado de usuários do Programa Automonitoramento Glicêmico

O trabalho relata, de maneira sistematizada e crítica, a experiência de um Projeto de Extensão no período de 2010 a 2011. Teve como foco ações de educação em saúde como estratégia para melhorar a adesão das pessoas com diabetes mellitus e insulinodependentes, de uma Unidade Básica de Saúde do município de São Paulo, ao Programa Automonitoramento Glicêmico. Além disso, pretendeu-se contribuir na reorganização do processo de trabalho em relação ao Programa na unidade. Foram utilizadas estratégias de educação em saúde em grupos educativos e visitas domiciliares, assim, possibilitando cuidados mais singulares. Dados dos usuários foram organizados em planilha e em pastas para as equipes de Saúde da Família, facilitando na identificação dos usuários, inclusive os faltosos, e auxiliando na descentralização do cuidado. Com as ações de educação em saúde, pretendeu-se contribuir para um cuidado mais integral e emancipatório aos usuários, para um contínuo refletir dos trabalhadores quanto a suas práticas.

Evidence-based clinical use of insulin premixtures

Brazil is expected to have 19.6 million patients with diabetes by the year 2030. A key concept in the treatment of type 2 diabetes mellitus (T2DM) is establishing individualized glycemic goals based on each patient’s clinical characteristics, which impact the choice of antihyperglycemic therapy. Targets for glycemic control, including fasting blood glucose, postprandial blood glucose, and glycated hemoglobin (A1C), are often not reached solely with antihyperglycemic therapy, and insulin therapy is often required. Basal insulin is considered an initial strategy; however, premixed insulins are convenient and are equally or more effective, especially for patients who require both basal and prandial control but desire a more simplified strategy involving fewer daily injections than a basal-bolus regimen. Most physicians are reluctant to transition patients to insulin treatment due to inappropriate assumptions and insufficient information. We conducted a nonsystematic review in PubMed and identified the most relevant and recently published articles that compared the use of premixed insulin versus basal insulin analogues used alone or in combination with rapid-acting insulin analogues before meals in patients with T2DM. These studies suggest that premixed insulin analogues are equally or more effective in reducing A1C compared to basal insulin analogues alone in spite of the small increase in the risk of nonsevere hypoglycemic events and nonclinically significant weight gain. Premixed insulin analogues can be used in insulin-naïve patients, in patients already on basal insulin therapy, and those using basal-bolus therapy who are noncompliant with blood glucose self-monitoring and titration of multiple insulin doses. We additionally provide practical aspects related to titration for the specific premixed insulin analogue formulations commercially available in Brazil.

Outcomes and cost effectiveness of treating type 2 diabetes with a nurse case manager following treatment algorithms versus primary care physicians

Background. Diabetes places a significant burden on the health care system. Reduction in blood glucose levels (HbA1c) reduces the risk of complications; however, little is known about the impact of disease management programs on medical costs for patients with diabetes. In 2001, economic costs associated with diabetes totaled $100 billion, and indirect costs totaled $54 billion. ^ Objective. To compare outcomes of nurse case management by treatment algorithms with conventional primary care for glycemic control and cardiovascular risk factors in type 2 diabetic patients in a low-income Mexican American community-based setting, and to compare the cost effectiveness of the two programs. Patient compliance was also assessed. ^ Research design and methods. An observational group-comparison to evaluate a treatment intervention for type 2 diabetes management was implemented at three out-patient health facilities in San Antonio, Texas. All eligible type 2 diabetic patients attending the clinics during 1994–1996 became part of the study. Data were obtained from the study database, medical records, hospital accounting, and pharmacy cost lists, and entered into a computerized database. Three groups were compared: a Community Clinic Nurse Case Manager (CC-TA) following treatment algorithms, a University Clinic Nurse Case Manager (UC-TA) following treatment algorithms, and Primary Care Physicians (PCP) following conventional care practices at a Family Practice Clinic. The algorithms provided a disease management model specifically for hyperglycemia, dyslipidemia, hypertension, and microalbuminuria that progressively moved the patient toward ideal goals through adjustments in medication, self-monitoring of blood glucose, meal planning, and reinforcement of diet and exercise. Cost effectiveness of hemoglobin AI, final endpoints was compared. ^ Results. There were 358 patients analyzed: 106 patients in CC-TA, 170 patients in UC-TA, and 82 patients in PCP groups. Change in hemoglobin A1c (HbA1c) was the primary outcome measured. HbA1c results were presented at baseline, 6 and 12 months for CC-TA (10.4%, 7.1%, 7.3%), UC-TA (10.5%, 7.1%, 7.2%), and PCP (10.0%, 8.5%, 8.7%). Mean patient compliance was 81%. Levels of cost effectiveness were significantly different between clinics. ^ Conclusion. Nurse case management with treatment algorithms significantly improved glycemic control in patients with type 2 diabetes, and was more cost effective. ^

Control glucémico a través del ejercicio físico en pacientes con diabetes mellitus tipo 2; revisión sistemática

Introducción: En España, cerca del 14% de la población es diabética y el 95% corresponde a DM2. Un pobre control glucémico provoca un aumento de la morbilidad y mortalidad. Tres son los pilares en el tratamiento de la DM2: la dieta, la medicación y el ejercicio físico, sin embargo, el potencial de la prescripción de entrenamiento físico no ha sido totalmente explotado. Objetivo: Analizar el efecto de las distintas modalidades de ejercicio físico (AE, RT, Combo, INT) en el control glucémico en pacientes con diabetes mellitus tipo 2. Métodos: La búsqueda bibliográfica se realizó en 3 bases de datos electrónicas (Pubmed, Scopus y Proquest), incluyendo publicaciones desde enero de 2011 hasta mayo de 2014, que realizaran la intervención con AE, RT, Combo o INT, y que midieran la glucemia a través de la glucosa capilar, CGMS o HbA1c. Resultados: Del total de 386 artículos encontrados, 14 cumplieron los criterios de inclusión. Estos artículos fueron clasificados atendiendo a la modalidad de ejercicio físico de la intervención (AE, RT, Combo, INT), y en función de si analizaban el control glucémico como consecuencia del entrenamiento a largo plazo o tras una sesión de entrenamiento. Conclusiones: El AE, RT, Combo e INT muestran eficacia en el control glucémico tanto en el entrenamiento prolongado como en las 24-48h post-entrenamiento. Es necesaria la prescripción de un entrenamiento estructurado con una frecuencia, volumen e intensidad determinados para lograr beneficios en el control glucémico. El combo es la modalidad que obtiene mejores resultados a través del entrenamiento a largo plazo.

The relationship between self-awareness of attentional status, behavioral performance and oscillatory brain rhythms

High-level cognitive factors, including self-awareness, are believed to play an important role in human visual perception. The principal aim of this study was to determine whether oscillatory brain rhythms play a role in the neural processes involved in self-monitoring attentional status. To do so we measured cortical activity using magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) while participants were asked to self-monitor their internal status, only initiating the presentation of a stimulus when they perceived their attentional focus to be maximal. We employed a hierarchical Bayesian method that uses fMRI results as soft-constrained spatial information to solve the MEG inverse problem, allowing us to estimate cortical currents in the order of millimeters and milliseconds. Our results show that, during self-monitoring of internal status, there was a sustained decrease in power within the 7-13 Hz (alpha) range in the rostral cingulate motor area (rCMA) on the human medial wall, beginning approximately 430 msec after the trial start (p < 0.05, FDR corrected). We also show that gamma-band power (41-47 Hz) within this area was positively correlated with task performance from 40-640 msec after the trial start (r = 0.71, p < 0.05). We conclude: (1) the rCMA is involved in processes governing self-monitoring of internal status; and (2) the qualitative differences between alpha and gamma activity are reflective of their different roles in self-monitoring internal states. We suggest that alpha suppression may reflect a strengthening of top-down interareal connections, while a positive correlation between gamma activity and task performance indicates that gamma may play an important role in guiding visuomotor behavior. © 2013 Yamagishi et al.

Relational diversity, social integration and individual effectiveness: a social self-regulation perspective

Relational demographers and dissimilarity researchers contend that group members who are dissimilar (vs. similar) to their peers in terms of a given diversity attribute (e.g. demographics, attitudes, values or traits) feel less attached to their work group, experience less satisfying and more conflicted relationships with their colleagues, and consequently are less effective. However, qualitative reviews suggest empirical findings tend to be weak and inconsistent (Chattopadhyay, Tluchowska and George, 2004; Riordan, 2000; Tsui and Gutek, 1999), and that it remains unclear when, how and to what extent such differences (i.e. relational diversity) affect group members social integration (i.e. attachment with their work group, satisfaction and conflicted relationships with their peers) and effectiveness (Riordan, 2000). This absence of meta-analytically derived effect size estimates and the lack of an integrative theoretical framework leave practitioners with inconclusive advice regarding whether the effects elicited by relational diversity are practically relevant, and if so how these should be managed. The current research develops an integrative theoretical framework, which it tests by using meta-analysis techniques and adding two further empirical studies to the literature. The first study reports a meta-analytic integration of the results of 129 tests of the relationship between relational diversity with social integration and individual effectiveness. Using meta-analytic and structural equation modelling techniques, it shows different effects of surface- and deep-level relational diversity on social integration Specifically, low levels of interdependence accentuated the negative effects of surface-level relational diversity on social integration, while high levels of interdependence accentuated the negative effects of deep-level relational diversity on social integration. The second study builds on a social self-regulation framework (Abrams, 1994) and suggests that under high levels of interdependence relational diversity is not one but two things: visibility and separation. Using ethnicity as a prominent example it was proposed that separation has a negative effect on group members effectiveness leading for those high in visibility and low in separation to overall positive additive effects, while to overall negative additive effects for those low in visibility and high in separation. These propositions were sustained in a sample of 621 business students working in 135 ethnically diverse work groups in a business simulation course over a period of 24 weeks. The third study suggests visibility has a positive effect on group members self-monitoring, while separation has a negative effect. The study proposed that high levels of visibility and low levels of separation lead to overall positive additive effects on self-monitoring but overall negative additive effects for those low in visibility and high in separation. Results from four waves of data on 261 business students working in 69 ethnically diverse work groups in a business simulation course held over a period of 24 weeks support these propositions.
