ABSTRACT

Communication between health professionals and patients is an intergroup phenomenon where the health professional has the most power and status. Over the past few decades, there has been a steady increase in the availability to patients of information about healthcare and specific diseases on the Internet. In this paper, we ask whether the use of Internet health information assists patients to manage their consultations with health professionals better and whether it alters the intergroup dynamic by providing a more equal status for patients. In this study 370 participants from Australia and Canada completed a survey that included a ‘willingness to communicate with health professionals’ scale. They also commented on their use and trust of Internet health information. Thematic analysis suggests that patients’ use of Internet health information serves as a broker between patients and their health provider in health consultations. We discuss the implications of these findings for health practitioners as they address how easier Internet access influences patient interactions with health professionals. We consider future research directions these finding provide in explaining communication behaviour in this context.  相似文献

Allogeneic hematopoietic stem cell transplantation (HSCT) is established therapy for selected patients with acute leukemia. After transplantation, antileukemic immune responses are believed to eliminate residual leukemia cells and decrease the likelihood of relapse. However, the clinical effect of successful antigen-specific immune reconstitution after HSCT on the likelihood of leukemic relapse and overall survival is not known. Pediatric recipients of unrelated cord blood transplants who underwent transplantation for acute leukemia were sequentially evaluated for their development of antigen-specific T-lymphocyte immunity to herpes viruses. The clinical effect of a positive antigen-specific response on relapse-free survival was determined. The presence of an antigen-specific response resulted in a relapse-free survival advantage (P = .0001), which was primarily due to a decrease in leukemic relapse (P = .003). Proportional hazards modeling for time to relapse and time to relapse or death defined 3 variables that were strongly associated with a poor outcome: female gender, poor remission status before transplantation, and negative antigen-specific T-lymphocyte proliferation. Notably neither acute nor chronic graft-versus-host disease had any effect on the incidence of leukemic relapse. Successful antigen-specific immune reconstitution after unrelated cord blood transplantation results in decreased leukemic relapse and improved overall survival.  相似文献

ABSTRACT: This study used formative evaluation to identify channels and barriers to providing ongoing dietary guidance to pregnant teens in New Jersey. In phase one, 14 health and social service professionals participated in a focus group or interview about nutrition services for pregnant teens. Participants identified school nurses as potential providers of early and continuous dietary counseling to pregnant teen-agers, but delineated barriers to establishment and effectiveness of school-based, prenatal nutrition education. In phase two, school nurses were surveyed to assess their interest in, and perceptions of barriers to, providing nutrition education to pregnant adolescents. Two-hundred fifty-three nurses (71%) returned completed questionnaires. Results indicated that a significant proportion perceived a need for, and were interested in providing, nutrition education to pregnant students. Results from this formative research are being used to guide development of a school-based nutrition education program for pregnant teen-agers in New Jersey.  相似文献

Public concern surrounding antibiotic contamination in food and food products has made it imperative to develop analytical methods for their detection. Polyclonal antibodies were used in the development of a surface plasmon resonance (SPR)-based inhibition immunoassay for cephalexin. A conjugate consisting of cephalexin-bovine serum albumin (BSA) was immobilized on the dextran gel surface of the sensor chip. Binding/regeneration studies of antibody to immobilized cephalexin were studied and dissociation of the antibody from the immobilized cephalexin was easily achieved with 10 mmol l-1 NaOH. Forty surface regeneration cycles were carried out and found to be reproducible with only a 7.4% decrease in binding over this number of regenerations. Model inhibition immunoassays for cephalexin were developed in PBS and spiked milk samples with detection ranges of 4.88 to 2,500 ng ml-1 and 244 to 3,906 pg ml-1, respectively.  相似文献

Screening for osteoporotic vertebral fractures traditionally involves X-ray of the thoracic and lumbar spine. We evaluated use of dual energy X-ray technology in patients with osteoporosis. We found this technology useful in the clinic setting and it has advantages in that less radiation is delivered to the patient.  相似文献

The objective of the study was to conduct a process and outcomes evaluation of the International AIDS Conference (IAC). Reaction evaluation data are presented from a delegate survey distributed at the 2004 IAC held in Thailand. Input and output data from the Thailand IAC are compared to data from previous IACs to ascertain attendance and reaction trends, which delegates benefit most, and host country effects. Outcomes effectiveness data were collected via a survey and intercept interviews. Data suggest that the host country may significantly affect the number and quality of basic science IAC presentations, who attends, and who benefits most. Intended and executed HIV work‐related behavior change was assessed under 9 classifications. Delegates who attended 1 previous IAC were more likely to report behavior changes than attendees who attended more than 1 previous IAC. The conference needs to be continually evaluated to elicit the required data to plan effective future IACs.  相似文献

Critics of Kohlberg's moral theory today focus on the content of his theory and more specifically on its justice-orientated moral concept. This has led to the well-known 'justice-care debate'. The purpose of this article is to critically examine the validity of Kohlberg's moral theory for research in nursing ethics from a caring perspective (referring to the content) as well as from a cognitive-structural perspective (referring to the basic assumptions of the model). The analysis points to the usefulness and value of the cognitive-structural model to empirically study nurses' ethical behaviour; the content of Kohlberg's model, however, needs to be adapted by adding a caring perspective as well as some personal and situational variables. An adjusted version of Kohlberg's model is proposed and discussed.  相似文献

Our work concerned 15 patients (9 males, 6 females) with a mean age of 29.5 years, having a hematologic malignant disease and undergoing allogenic bone marrow transplantation.We studied :
1. The metabolic disorders induced by the conditioning regimen (chemotherapy and total body irradiation) pregraft accompanying cytolysis (day −7, −5, −2).
2. The corrective effect of a total parenteral nutrition introduced 2 days before the transplantation and pursued during 30 days post-graft (day −2 to day 30).
3. The interest of a high calorie intake (BEE × 2) and, after randomisation, of a variable nitrogen intake (24% of the total calorie intake for group A [8 patients] and 14% for group B [7 patients]). The patient characteristics of these two groups were closely comparable. Urinary parameters were studied daily (3-methylhistidine, cratinine, nitrogen) and blood parameters weekly (transferrin, pre-albumin, albumin, retinol binding protein).
We observed globally :
-- An excellent result of the nutritional support without significant weight loss;
-- protein catabolism stopped with a recovery of synthesis of RBP after day 7 and pre-albumin from day 7;
-- a decrease in muscle catabolism.
The randomized study showed :
-- a significant difference in nitrogen excretion between group A and group B;
-- earlier and better protein synthesis recovery in group A, particularly with regard to RBP and pre-albumin.
In conclusion, we recommend for the patients undergoing bone marrow transplantation :
-- nutritional support should be introduced before the conditioning regimen;
-- a high calorie intake (BEE × 2) with a nitrogen intake between 14% and 24% of the total calorie intake;
-- cyclic parenteral nutrition should be pursued during the second and third month post-graft.

Résumé

Nous avons étudié chez 15 malades (9 hommes, 6 femmes) d'âge moyen 29,5 ans, présentant une hémopathie maligne et nécessitant une greffe de moelle osseuse allogénique :
1. Les désordres métaboliques induits par la chimiothérapie et l'irradiation corporelle totale en période de prégreffe au cours de la cytolyse (J −7, J −5, J −2).
2. L'effet correcteur d'une nutrition parentérale introduite deux jours avant la greffe et exclusive durant les 30 jours post-greffe (J −2, J + 30).
3. L'intérêt d'un apport calorique élevé (BEE × 2) et, par randomisation, d'un apport azoté variable (24 % de l'apport calorique total pour le groupe A et 14 % pour le groupe B).
Nous avons étudié quotidiennement certains paramètres urinaires (3MeH, créatinine, azote) et les paramètres sanguins (transferrine, préalbumine, albumine, RBP) l'ont été de façon hebdomadaire.Nous avons constaté globalement un excellent résultat du support nutritif sans perte de poids significative, un arrêt du processus catabolique protéique avec reprise de synthèse après J +7 pour la RBP et pour la préalbumine et une réduction du catabolisme musculaire.L'étude randomisée a mis en évidence :
-- une différence statistique dans l'excrétion axotée, plus intense dans le groupe A,
-- une reprise des synthèses protéiques, plus précoce et plus performante dans ce même groupe pour la RBP et la préalbumine.
En conclusion et compte tenu de l'ensemble des éléments, nous préconisons chez ces malades devant subir une greffe de moelle osseuse allogénique :
-- une attitude préventive en ce qui concerne la nutrition à débuter avant le conditionnement,
-- un apport calorique élevé (BEE × 2) et un apport azoté situé entre 14 % et 24 % de l'apport calorique total,
-- une étude prospective quant à l'intérêt de certains acides aminés et d'une nutrition parentérale cyclique poursuivie au 2e et au 3e mois post-greffe.

The effectiveness of galactomannan detection with the Platelia test was evaluated in a prospective study of 3,327 sera from 807 patients. The specificity was 99.6% (748 of 751 cases). For the groups of patients with proven and probable invasive aspergillosis, the sensitivity was 50.0% (17 of 34 cases). The disappointing sensitivity associated with the presence of rare false-positive cases underlines the limits of this test.  相似文献
