Food allergy in Catalonia: Clinical manifestations and its association with airborne allergens.

BACKGROUND: Food allergy affects around 6% of the European population and its prevalence worldwide has been increasing in the last decades, but studies focused on investigating food allergy epidemiology in Europe are lacking. OBJECTIVE: The Cibus project was created to register the main culprit foods and their clinical manifestations in food allergic patients in Catalonia. METHODS: A specific online database was designed. Allergists from eight different Catalan hospitals registered the new diagnoses of food allergy. RESULTS: 618 food allergic patients were included. Egg and milk were the main elicitors in the early ages, while fruits and nuts were the most frequent in patients >14 years old. Fish was more frequent in children, while seafood and Anisakis allergy were more frequent in the >14-year-old group. Overall, peach was the most prevalent food eliciting an allergic reaction (10%). Food allergy diagnosis was reached using compatible clinical history and positive skin prick test to the involved food in 98% of cases. Globally, urticaria was the most frequently reported manifestation in our population (48.2%), followed by oral allergy syndrome (25.6%) and anaphylaxis (24.8%). CONCLUSIONS: The Cibus project gives a full overview of the profile of food allergic patients in Catalonia and reinforces the predominance of plant food allergies in the Mediterranean area.

[Perception of UCI nurses in relation with satisfactory care: convergences and divergences with the perception of critical patients]. / Percepción de las enfermeras de UCI en relación al cuidado satisfactorio: convergencias y divergencias con la percepción del paciente crítico.

OBJECTIVE: Explore convergences and divergences between perception of nurses and of critically ill patients, in relation to the satisfactory care given and received. METHODS: It is part of a larger qualitative study, according to the Grounded Theory. Carried out in 3 intensive care units with 34 boxes. Sampling theoretical profiles with n=19 patients and n=7 nurses after data saturation. Recruitment of patients included in the profiles of elderly and long-stay got stretched over some time due to the low incidence of cases. Data collection consisted of: in-depth interview to critically ill patients, group discussion of expert nurses in the critical care patient and field diary. Analysis themed on Grounded Theory according Strauss and Corbin: open coding, axial and selective. Analysis followed criteria of Guba and Lincoln rigor, Calderón quality and Gastaldo and McKeever ethical reflexivity. There was a favorable report from the ethical committee of the Hospital and informed consent of the participants. RESULTS: Four matching categories were found: professional skills, human, technical and continued care. Combination of these elements creates feelings of security, calmness and feeling like a person, allowing the patient a close and trusting relationship with the nurse who takes individualized care. Not divergent categories were found. CONCLUSIONS: Perceptions of nurses in relation to care match perceptions of critically ill patients in both the definition and dimensions upon satisfactory care.

Development of an instrument to measure the degree of critical patient's satisfaction with nursing care: research protocol.

AIM: To investigate and understand patient's satisfaction with nursing care in the intensive care unit to identify the dimensions of the concept of 'satisfaction' from the patient's point of view. To design and validate a questionnaire that measures satisfaction levels in critical patients. BACKGROUND: There are many instruments capable of measuring satisfaction with nursing care; however, they do not address the reality for critical patients nor are they applicable in our context. DESIGN: A dual approach study comprising: a qualitative phase employing Grounded Theory and a quantitative and descriptive phase to prepare and validate the questionnaire. METHODS: Data collection in the qualitative phase will consist of: in-depth interview after theoretical sampling, on-site diary and expert discussion group. The sample size will depend on the expected theoretical saturation n = 27-36. Analysis will be based on Grounded Theory. For the quantitative phase, the sampling will be based on convenience (n = 200). A questionnaire will be designed on the basis of qualitative data. Descriptive and inferential statistics will be used. The validation will be developed on the basis of the validity of the content, the criteria of the construct and reliability of the instrument by the Cronbach's alpha and test-retest approach. Approval date for this protocol was November 2010. DISCUSSION: Self-perceptions, beliefs, experiences, demographic, socio-cultural epistemological and political factors are determinants for satisfaction, and these should be taken into account when compiling a questionnaire on satisfaction with nursing care among critical patients.

[Perception of the critical patient on nursing cares: an approach to the concept of satisfaction]. / La percepción del paciente crítico sobre los cuidados enfermeros: una aproximación al concepto de satisfacción.

INTRODUCTION: Level of satisfaction is a key indicator of quality of care. There are many tools that measure satisfaction with nursing care, however they do not respond to the reality of the critical care patient or to our context. OBJECTIVES: To define and to identify the dimensions of the satisfaction of patients admitted to the intensive care unit of a tertiary hospital with nursing cares and to define and identify the dimensions of the concept of satisfaction from their point of view. MATERIAL AND METHODS: A qualitative research study was conducted according to the Grounded Theory Method in three Intensive Care Units with 34 individual boxes, with theoretical sampling. Nineteen patients remained after data saturation sampling. Data collection was obtained through recorded in-depth interviews and field logbook. Contents analysis was made according to the Grounded Theory. Guba and Lincoln rigor's criteria were followed. There was a favorable report from the Hospital's Ethics Committee and informed consent was obtained from the patients. RESULTS: Four categories were found: The definition and dimensions of the satisfaction concept, expectations and life experiences. The participants included the following dimensions in their satisfaction definition: professional competences, human, technical and continuous cares. The combination of these elements produces feelings of security, calmness, being monitored, feeling like a person, perceiving a close relationship and trustfulness with the nurse who performs the individualized cares. CONCLUSIONS: The definition and dimensions of satisfaction concept from the patient's point of view show the important aspects of the person and also clarify their dimensions, allowing the construction of tools more in line with the context and real perception.

Human seminal plasma allergy and successful pregnancy.

Human seminal plasma allergy in women is an uncommon phenomenon. A great variety of reactions ranging from local swelling to generalized systemic reactions have been described, and local symptoms have often been misdiagnosed as chronic vulvovaginitis. Sperm barriers, such as condoms, are the most widely advocated method for avoiding these reactions; however this is not acceptable to couples who wish to have children. We present a case of a woman with human seminal plasma allergy who became pregnant after a fourth cycle of artificial insemination. Sodium dodecyl sulfate polyacrylamide gel electrophoresis immunoblotting showing an IgE binding band at 28kDa in the husband's seminal fluid identified the culprit allergen. Artificial insemination is an effective way to achieve a pregnancy in patients with seminal plasma allergy.

An observational study on outgrowing food allergy during non-birch pollen-specific, subcutaneous immunotherapy.

BACKGROUND: Birch pollen-specific immunotherapy (SIT) decreases allergy to foods containing birch pollen-homologous allergens. Cross-reactivity was also observed between plane tree pollen and some vegetable foods. OBJECTIVE: The aim of this study was to evaluate the outgrowing of food allergy by patients suffering from vegetable food allergy associated with plane tree pollinosis (rhinoconjunctivitis and/or asthma) during plane tree pollen SIT. METHODS: An observational and prospective study was conducted in 16 adult patients suffering from vegetable food allergy (hazelnut, walnut, lettuce, peach and cherry) and from plane tree pollinosis receiving plane tree pollen SIT for 1 year. Open oral challenges with the implicated food were performed before and after SIT. Blood samples were drawn for measurement of pollen- and food-specific IgE and IgG4 before and after treatment. RESULTS: Plane tree SIT resulted in a significant decrease in food allergy, since the mean food quantity provoking objective symptoms increased from 2.19 to 13.74 g (p < 0.05), and 6 of the 11 patients tolerated the highest level (25 g) of the challenged food after plane tree SIT. Laboratory data also showed a decrease in IgE levels and an increase in IgG4 levels after immunotherapy. CONCLUSION: SIT with plane tree pollen has a positive impact on food allergy in plane tree pollen-allergic subjects.
