Clinical factors associated with a Candida albicans Germ Tube Antibody positive test in Intensive Care Unit patients

Background: Poor outcomes of invasive candidiasis (IC) are associated with the difficulty in establishing the microbiological diagnosis at an early stage. New scores and laboratory tests have been developed in order to make an early therapeutic intervention in an attempt to reduce the high mortality associated with invasive fungal infections. Candida albicans IFA IgG has been recently commercialized for germ tube antibody detection (CAGTA). This test provides a rapid and simple diagnosis of IC (84.4% sensitivity and 94.7% specificity). The aim of this study is to identify the patients who could be benefited by the use of CAGTA test in critical care setting. Methods: A prospective, cohort, observational multicentre study was carried out in six medical/surgical Intensive care units (ICU) of tertiary-care Spanish hospitals. Candida albicans Germ Tube Antibody test was performed twice a week if predetermined risk factors were present, and serologically demonstrated candidiasis was considered if the testing serum dilution was >= 1: 160 in at least one sample and no other microbiological evidence of invasive candidiasis was found. Results: Fifty-three critically ill non-neutropenic patients (37.7% post surgery) were included. Twenty-two patients (41.5%) had CAGTA-positive results, none of them with positive blood culture for Candida. Neither corrected colonization index nor antifungal treatment had influence on CAGTA results. This finding could corroborate that the CAGTA may be an important biomarker to distinguish between colonization and infection in these patients. The presence of acute renal failure at the beginning of the study was more frequent in CAGTA-negative patients. Previous surgery was statistically more frequent in CAGTA-positive patients. Conclusions: This study identified previous surgery as the principal clinical factor associated with CAGTA-positive results and emphasises the utility of this promising technique, which was not influenced by high Candida colonization or antifungal treatment. Our results suggest that detection of CAGTA may be important for the diagnosis of invasive candidiasis in surgical patients admitted in ICU.

Somatisation in primary care: experiences of primary care physicians involved in a training program and in a randomised controlled trial

Background: A new intervention aimed at managing patients with medically unexplained symptoms (MUS) based on a specific set of communication techniques was developed, and tested in a cluster randomised clinical trial. Due to the modest results obtained and in order to improve our intervention we need to know the GPs' attitudes towards patients with MUS, their experience, expectations and the utility of the communication techniques we proposed and the feasibility of implementing them. Physicians who took part in 2 different training programs and in a randomised controlled trial (RCT) for patients with MUS were questioned to ascertain the reasons for the doctors' participation in the trial and the attitudes, experiences and expectations of GPs about the intervention. Methods: A qualitative study based on four focus groups with GPs who took part in a RCT. A content analysis was carried out. Results: Following the RCT patients are perceived as true suffering persons, and the relationship with them has improved in GPs of both groups. GPs mostly valued the fact that it is highly structured, that it made possible a more comfortable relationship and that it could be applied to a broad spectrum of patients with psychosocial problems. Nevertheless, all participants consider that change in patients is necessary; GPs in the intervention group remarked that that is extremely difficult to achieve. Conclusion: GPs positively evaluate the communication techniques and the interventions that help in understanding patient suffering, and express the enormous difficulties in handling change in patients. These findings provide information on the direction in which efforts for improving intervention should be directed.

Representações sociais do câncer para o familiar do paciente oncológico em tratamento quimioterápico

Considerando-se que a família vivencia e partilha junto com o doente todos os sentimentos, emoções e angústias que envolve o diagnóstico e o tratamento do câncer, o presente estudo teve como objetivos descrever as dimensões das representações sociais acerca do câncer para familiares do cliente oncológico em tratamento quimioterápico ambulatorial em uma unidade de referência para o seu tratamento; analisar a representação social do câncer elaborada por familiares do cliente oncológico em tratamento quimioterápico ambulatorial; e discutir as contribuições do enfermeiro junto à família do cliente oncológico em tratamento quimioterápico ambulatorial a partir da construção representacional do câncer para os sujeitos do estudo. De caráter qualitativo, o caminho metodológico foi construído com base na Teoria das Representações Sociais. Os sujeitos foram 30 familiares que estavam acompanhando o doente durante o tratamento quimioterápico. Os dados foram coletados a partir da realização de entrevistas semi-estruturadas e analisados através da análise de conteúdo de Bardin (1979), sistematizada por Oliveira (2008), com o auxílio do software QRS Nvivo 2.0. Da análise dos dados emergiram seis categorias que compõem o campo representacional e se expressa através das dimensões representacionais concretizadas nas seguintes categorias: sentimentos compartilhados por familiares de clientes oncológicos em tratamento quimioterápico, que mostra que, ao se depararem com a doença e sua dura realidade, os familiares são acometidos por diversos tipos de sentimentos; imagens, metáforas e conceitos no existir da família que enfrenta a doença, onde os familiares revelaram que o câncer é percebido, entre outras coisas, como um monstro que invade a vida das pessoas e dela passa a tomar conta e a dominá-la; preconceitos e estigmas na vivência do câncer, que revelou que ainda hoje existem representações e estigmas presentes na sociedade e em suas construções culturais acerca do câncer; diferentes práticas desenvolvidas no contexto da doença e do processo de adoecimento pelo câncer, que evidenciou as diferentes práticas presentes no discurso dos sujeitos, quais sejam, a de religiosidade no contexto do câncer, a de enfrentamento da doença, a de comunicação-ocultamento e de atitudes da família ao estar no mundo frente ao câncer; o processo de ancoragem e o conhecimento adquirido após a experiência do câncer, onde surgiram os conhecimentos que os sujeitos adquiriram acerca do câncer e alguns elementos do processo de ancoragem do câncer; as vivências do enfermeiro que trabalha em oncologia e suas contribuições junto à família que alerta os enfermeiros para a necessidade de intervenções efetivas direcionadas à assistência integral do indivíduo, levando em consideração a importância da família. Conclui-se que ao se descobrir acompanhando um familiar que tem câncer, a família passa a viver um outro mundo, no qual a possibilidade de morte se mostra de forma inevitável e iminente. Diante disso, a família passa a valorizar não apenas o cuidado dispensado ao doente, mas também anseia por uma atenção profissional que contemple seu existir e seu modo de viver.

One-step digit-set-restricted modified signed-digit adder using an incoherent correlator based on a shared content-addressable memory

An efficient one-step digit-set-restricted modified signed-digit (MSD) adder based on symbolic substitution is presented. In this technique, carry propagation is avoided by introducing reference digits to restrict the intermediate carry and sum digits to {1,0} and {0,1}, respectively. The proposed technique requires significantly fewer minterms and simplifies system complexity compared to the reported one-step MSD addition techniques. An incoherent correlator based on an optoelectronic shared content-addressable memory processor is suggested to perform the addition operation. In this technique, only one set of minterms needs to be stored, independent of the operand length. (C) 2002 society or Photo-Optical Instrumentation Engineers.
