Safe administration of noradrenaline by the peripheral route: A systematic review. / Administración segura de noradrenalina por vía periférica: una revisión sistemática.

PURPOSE: To review and analyze the available literature on peripheral administration of noradrenaline (NA) with the aim of providing recommendations to ensure correct use and patient safety. METHODS: Systematic review on the databases PubMed, ISI Web of Science, SCOPUS and Science Direct, using the following search terms: ("Noradrenaline" [Mesh]) AND ("Norepinephrine" [Mesh]) AND ("Vasopressors" [Mesh]) AND ("Peripheral infusions" [Mesh]) OR ("Extravasations" [Mesh]). A total of 1,040 articles were identified. Animal studies and studies written in languages other than English were excluded. Finally, 83 articles were included. RESULTS: NA can be administered peripherally. The risk of extravasation should be taken into account, with phentolamine being the first pharmacological line of treatment. It has also been related to the appearance of thrombophlebitis, cellulitis, tissue necrosis, limb ischemia and gangrene, although its incidence seems to be low. The use of peripheral NA in children seems to be carried out without obvious complications. The use of standard concentrations is suggested to reduce the risk of errors. It is recommended to use 0.9% saline as the default diluent for peripheral NA. CONCLUSIONS: Peripheral infusions of NA could be a safe and beneficial option in early resuscitation provided that a number of guidelines are followed that reduce the likelihood of complications associated with this route.

Feeding difficulties in children with food allergies: An EAACI Task Force Report.

The term "feeding difficulties" refers to a spectrum of phenotypes characterized by suboptimal intake of food and/or lack of age-appropriate eating habits. While it is evident that feeding difficulties are prevalent within healthy children, no consensus has been reached for those with food allergies. The aim of this study was to systematically review all the available literature reporting the prevalence of feeding difficulties within food allergic children. We searched eight international electronic databases for all published studies until June 2022. International experts in the field were also contacted for unpublished and ongoing studies. All publications were screened against pre-defined eligibility criteria and critically appraised by established instruments. The substantial heterogeneity of included studies precluded meta-analyses, so narrative synthesis of quantitative data was performed. A total of 2059 abstracts were assessed, out of which 21 underwent full-text screening and 10 studies met the study criteria. In these, 12 different terms to define feeding difficulties and 11 diagnostic tools were used. Five papers included data of feeding difficulty prevalence in children with food allergies, ranging from 13.6% to 40%. Higher prevalence was associated with multiple food allergies. The current literature suggests that feeding difficulties are prevalent within food allergic children, particularly those with multiple food allergies. However, the heterogeneity of terminologies and diagnostic tools makes drawing conclusions challenging. Consensus guidelines for the diagnosis and management of feeding difficulties within food allergic children and further research on the development and perpetuation of feeding difficulties are needed to appropriately manage such patients.

Asthma and rhinitis control in adolescents and young adults: A real-world MASK-air study.

BACKGROUND: In allergic rhinitis and asthma, adolescents and young adult patients are likely to differ from older patients. We compared adolescents, young adults and adults on symptoms, control levels, and medication adherence. METHODS: In a cross-sectional study (2015-2022), we assessed European users of the MASK-air mHealth app of three age groups: adolescents (13-18 years), young adults (18-26 years), and adults (>26 years). We compared them on their reported rhinitis and asthma symptoms, use and adherence to rhinitis and asthma treatment and app adherence. Allergy symptoms and control were assessed by means of visual analogue scales (VASs) on rhinitis or asthma, the combined symptom-medication score (CSMS), and the electronic daily control score for asthma (e-DASTHMA). We built multivariable regression models to compare symptoms or medication accounting for potential differences in demographic characteristics and baseline severity. RESULTS: We assessed 965 adolescent users (15,252 days), 4595 young adults (58,161 days), and 15,154 adult users (258,796 days). Users of all three age groups displayed similar app adherence. In multivariable models, age groups were not found to significantly differ in their adherence to rhinitis or asthma medication. These models also found that adolescents reported lower VAS on global allergy, ocular, and asthma symptoms (as well as lower CSMS) than young adults and adults. CONCLUSIONS: Adolescents reported a better rhinitis and asthma control than young adults and adults, even though similar medication adherence levels were observed across age groups. These results pave the way for future studies on understanding how adolescents control their allergic diseases.

Evaluation of clinical outcomes of efficacy in food allergen immunotherapy trials, COFAITH EAACI task force.

Food allergy is a global public health problem that until recent years lacked any aetiological treatment supported by academy, industry and regulators. Food immunotherapy (AIT) is an evolving treatment option, supported by clinical practice and industry trial data. Recent AIT meta-analyses have highlighted the difficulty in pooling safety and efficacy data from AIT trials, due to secondary heterogeneity in the study. An EAACI task force (CO-FAITH) initiated by the Paediatric Section was created to focus on AIT efficacy outcomes for milk, egg and peanut allergy rather than in trial results. A systematic search and a narrative review of AIT controlled clinical trials and large case series was conducted. A total of 63 manuscripts met inclusion criteria, corresponding to 23, 21 and 22 studies of milk, egg and peanut AIT, respectively. The most common AIT efficacy outcome was desensitization, mostly defined as tolerating a maintenance phase dose, or reaching a particular dose upon successful exit oral food challenge (OFC). However, a large degree of heterogeneity was identified regarding the dose quantity defining this outcome. Sustained unresponsiveness and patient-reported outcomes (e.g. quality of life) were explored less frequently, and to date have been most rigorously described for peanut AIT versus other allergens. Change in allergen threshold assessed by OFC remains the most common efficacy measure, but OFC methods suffer from heterogeneity and methodological disparity. This review has identified multiple heterogeneous outcomes related to measuring the efficacy of AIT. Efforts to better standardize and harmonize which outcomes, and how to measure them must be carried out to help in the clinical development of safe and efficacious food allergy treatments.

Hyposalivation but not Sjögren's syndrome associated with microbial dysbiosis in women.

Background: Saliva modulates the environment of the oral biofilm through pH buffer, microbial attachment to host surfaces, and nutritional source. The ecology of stress occurs when a physical factor adversely impacts an ecosystem or its biotic components. Therefore, reduced salivary flow can affect oral-host balance. The leading causes of hyposalivation include disease-associated Sjögren's syndrome (SS) and menopausal women as aging-associated. However, little is known about the oral microbiome integrated with sex hormones in hyposalivation. This study aimed to characterize the hyposalivation microbiome caused by aging or disease affecting the salivary glands in women. Methods: We included 50 women older than 40 years of age in any menopausal phase. We collected stimulated saliva from 25 women diagnosed with SS (SS) and 25 without SS (non-SS). The bacterial profile of the patients was obtained by 16S rRNA sequencing. Bioinformatics analysis used machine learning to analyze the cohort's signs, symptoms, and bacterial profile. Salivary estradiol as a sex hormone variation level was determined. Results: We obtained that 79% of the SS group, and 52% of the non-SS group had hyposalivation. We found a negatively correlated Prevotella-age and Rothia-estradiol in the SS group. Highlight, we found that the cause of the hyposalivation in the study did not explain differences in microbial diversity comparing non-SS and SS groups. Therefore, microbial communities found in hyposalivation but not related to systemic conditions suggest that changes in the oral environment might underpin host-microbial balance. Conclusion: The salivary microbiome was similar in women with and without SS. However, hyposalivation showed two distinctive clusters associated with the bacterial population profiles. Our study suggests that local ecological disturbances could drive the change in the microbiome.

Aproximación a la Deontología en Medicina Legal en el contexto cubano

Se realizó una revisión bibliográfica con el objetivo de exponer cuestiones deontológicas inherentes a la práctica de la Medicina Legal y el estado de la temática en el contexto nacional. Se abordan los principales conflictos éticos derivados de la práctica pericial, las recomendaciones para las actuaciones de los peritos, el desarrollo de la especialidad en el país y la situación actual respecto a las normativas deontológicas. La escuela cubana de Medicina Legal asienta su práctica en las normas jurídicas y éticas del país, con un fuerte compromiso humanista. Se concluye que, las particularidades propias de la actividad pericial, demandan la creación de un código deontológico propio.

A bibliographical review was carried out with the objective of exposing deontological issues inherent to the practice of Legal Medicine and the state of the issue in the national context. The main ethical conflicts derived from the expert practice, the recommendations for the actions of the experts, the development of the specialty in the country and the current situation regarding the deontological regulations. The Cuban School of Legal Medicine established its practice in the legal and ethical norms of the country, with a strong humanist commitment. It is concluded that the particularities of expert activity, demand the creation of its own code of ethics.

Clinical and Biomarker Profile Responses to Rehabilitation Treatment in Patients with Long COVID Characterized by Chronic Fatigue.

Long COVID (LC) syndrome is a complex multiorgan symptom that persists beyond >12 weeks after SARS-CoV-2 infection. The most frequently associated symptom is fatigue. Physical activity and exercise are recommended, although specific studies are lacking. The objectives of the present work are to analyze the impact of a supervised exercise program on the clinical evolution of LC with fatigue patients and to identify whether certain circulating biomarkers could predict the response to rehabilitation. The rehabilitation treatment response was analyzed in 14 women diagnosed with LC and fatigue, based on the changes in the 6 min walk test and Borg/Fatigue Impact scales. Patients who showed improvement in the meters walked were considered "responders" to the therapy. A total of 65% of patients responded to the exercise program, with an improvement in the meters walked and in oxygen saturation, with stability in the percentage of meters walked. Participants with obesity and those double-vaccinated against SARS-CoV-2 presented a lower degree of fatigue. LC patients presented a favorable response to a supervised exercise program. Differences in creatinine and protein levels were observed between rehabilitation therapy "responders" and "nonresponders". A good state of protein nutrition was related to a better rehabilitation response. The results are promising regarding possible predictive biomarkers of rehabilitation response, such as creatinine.

Food Protein-induced Enterocolitis Syndrome Due to Cuttlefish in a Child with Anaphylaxis to Crustaceans.

Shellfish is defined as any edible marine invertebrate and refers to crustaceans and mollusks. Crustaceans belong to the phylum Arthropods. Mollusks belong to the phylum Mollusca. This report illustrates a rare case of a 6-year-old girl with challenge-proven acute food protein-induced enterocolitis syndrome (FPIES) to cuttlefish (phylum Mollusca, class Cephalopoda), anaphylaxis to crustaceans (phylum Arthropoda), and tolerance to other mollusks, including clams and mussels (phylum Mollusca, class Bivalvia). The association of IgE-mediated food allergy and acute FPIES seen in this case is rare. To our knowledge, this is the first case of FPIES to cuttlefish reported in a child. This challenge highlights the need for further research into the allergens and mechanisms underpinning FPIES at a molecular level, enabling a better understanding of cross-reactivity patterns and the development of diagnostic and predictive tests to assist in clinical practice.

WAO consensus on DEfinition of Food Allergy SEverity (DEFASE).

Background: While several scoring systems for the severity of anaphylactic reactions have been developed, there is a lack of consensus on definition and categorisation of severity of food allergy disease as a whole. Aim: To develop an international consensus on the severity of food allergy (DEfinition of Food Allergy Severity, DEFASE) scoring system, to be used globally. Methods Phase 1: We conducted a mixed-method systematic review (SR) of 11 databases for published and unpublished literature on severity of food allergy management and set up a panel of international experts. Phase 2: Based on our findings in Phase 1, we drafted statements for a two-round modified electronic Delphi (e-Delphi) survey. A purposefully selected multidisciplinary international expert panel on food allergy (n = 60) was identified and sent a structured questionnaire, including a set of statements on different domains of food allergy severity related to symptoms, health-related quality of life, and economic impact. Participants were asked to score their agreement on each statement on a 5-point Likert scale ranging from "strongly agree" to "strongly disagree". Median scores and percentage agreements were calculated. Consensus was defined a priori as being achieved if 70% or more of panel members rated a statement as "strongly agree" to "agree" after the second round. Based on feedback, 2 additional online voting rounds were conducted. Results: We received responses from 92% of Delphi panel members in round 1 and 85% in round 2. Consensus was achieved on the overall score and in all of the 5 specific key domains as essential components of the DEFASE score. Conclusions: The DEFASE score is the first comprehensive grading of food allergy severity that considers not only the severity of a single reaction, but the whole disease spectrum. An international consensus has been achieved regarding a scoring system for food allergy disease. It offers an evaluation grid, which may help to rate the severity of food allergy. Phase 3 will involve validating the scoring system in research settings, and implementing it in clinical practice.

A practical toolbox for the effective transition of adolescents and young adults with asthma and allergies: An EAACI position paper.

INTRODUCTION: Adolescence is a critical stage of rapid biological, emotional and social change and development. Adolescents and young adults (AYA) with asthma and allergies need to develop the knowledge and skills to self-manage their health independently. Healthcare professionals (HCP), parents and their wider network play an essential role in supporting AYA in this process. Previous work showed significant limitations in transition care across Europe. In 2020, the first evidence-based guideline on effective transition for AYA with asthma and allergies was published by EAACI. AIM: We herein summarize practical resources to support this guideline's implementation in clinical practice. METHODS: For this purpose, multi-stakeholder Task Force members searched for resources in peer review journals and grey literature. These resources were included if relevant and of good quality and were pragmatically rated for their evidence-basis and user friendliness. RESULTS: Resources identified covered a range of topics and targeted healthcare professionals, AYA, parents/carers, schools, workplace and wider community. Most resources were in English, web-based and had limited evidence-basis. CONCLUSIONS: This position paper provides a valuable selection of practical resources for all stakeholders to support effective transitional care for AYA with asthma and allergies. Future research should focus on developing validated, patient-centred tools to further assist evidence-based transition care.

Allergic diseases and immunodeficiencies in children, lessons learnt from COVID-19 pandemic by 2022: A statement from the EAACI-section on pediatrics.

By the April 12, 2022, the COVID-19 pandemic had resulted in over half a billion people being infected worldwide. There have been 6.1 million deaths directly due to the infection, but the pandemic has had many more short- and long-term pervasive effects on the physical and mental health of the population. Allergic diseases are among the most prevalent noncommunicable chronic diseases in the pediatric population, and health-care professionals and researchers were seeking answers since the beginning of pandemic. Children are at lower risk of developing severe COVID-19 or dying from infection. Allergic diseases are not associated with a higher COVID-19 severity and mortality, apart from severe/poorly controlled asthma. The pandemic disrupted routine health care, but many mitigation strategies, including but not limited to telemedicine, were successfully implemented to continue delivery of high-standard care. Although children faced a multitude of pandemic-related issues, allergic conditions were effectively treated remotely while reduction in air pollution and lack of contact with outdoor allergens resulted in improvement, particularly respiratory allergies. There is no evidence to recommend substantial changes to usual management modalities of allergic conditions in children, including allergen immunotherapy and use of biologicals. Allergic children are not at greater risk of multisystem inflammatory syndrome development, but some associations with Long COVID were reported, although the data are limited, and further research is needed. This statement of the EAACI Section on Pediatrics provides recommendations based on the lessons learnt from the pandemic, as available evidence.

Cognitive decline and brainstem hypometabolism in long COVID: A case series.

OBJECTIVE: To assess FDG cerebral PET in patients suffering from cognitive impairment linked to Long COVID. The COVID pandemic has affected dozens of millions of people around the world and has resulted in the deaths of more than 3 million people. Following the acute forms, it has been reported sometimes long forms of COVID, with involvements of several organs including the brain. Neurological complications can include cognitive disturbances (brain fog) that are very common and can seriously disturb the life of patients. METHODS: Fluorodeoxyglucose PETs were performed in 3 patients with cognitive decline following COVID infection. RESULTS: We report here 3 cases of brain fog with major hypometabolic areas of the pons revealed by the cerebral FDG PET. CONCLUSION: The dysfunction of the locus coeruleus in these patients could partly explain the cognitive disorders observed. Further studies involving larger cohorts of patients suffering from cognitive dysfunction will be needed to determine if the brainstem is frequently affected in these patients.

Oppression and resistance: An analysis of Muslims' experiences of structural violence.

Discrimination and vilification of Muslims in the United States have historical and political roots. This study explores everyday incidents of marginalization and oppression through the framework of structural violence. Structural violence refers to the systemic inequalities embedded within societal structures that create and support these oppressive conditions. In this community-engaged qualitative study, 10 self-identified Muslims from the northeastern United States were interviewed to understand their lived experiences of structural violence. Using thematic analysis, seven themes were identified: Racialized and xenophobic Islamophobia; normalized violence against Muslims and fear of safety; exclusion, marginalization, and subjugation through policies; Muslims as spokespersons for Islam; Intersecting marginalized identities and oppression; challenges of navigating Muslim identities; resilience and resistance through faith, activism, and community. This study aims to understand and contextualize the experiences of Muslims within a systemic and geopolitical framework. Another critical objective is to promote a discourse to address how academics and clinicians reproduce and maintain structural violence and to instead engage in socially transformative approaches embedded in the principles of decolonizing and mutually-liberating cross-struggle solidarity. These must be cultivated through community-informed intersectional collaborative strategies for dismantling oppressive structures and promoting agency, resilience, activism, and resistance.

Perceptions of adolescents and young adults with allergy and/or asthma and their parents on EAACI guideline recommendations about transitional care: A European survey.

BACKGROUND: The European Academy of Allergy and Clinical Immunology has developed a guideline to provide evidence-based recommendations for healthcare professionals to support the transitional care of adolescents and young adults (AYA) with allergy and/or asthma. The goal of this work was to ensure that the draft recommendations are also important for patients. METHODS: We surveyed patients aged 11-25 years with allergy and/or asthma and their parents across Europe between 17 February and 16 March 2020. The multilingual survey was distributed through national allergy and asthma patient organizations in Europe as well as through social media. RESULTS: A total of 1210 responses from 24 European countries were collected. There were 415 (34.3%) AYA and 795 (65.7%) parents. The majority of AYA (72.3%) and parents (81.9%) were female. Patients had a history of asthma (61.1%), allergic rhinoconjunctivitis (54.1%), food allergy (53.8%), atopic eczema (42.6%) and anaphylaxis (28.8%). All recommendations achieved the median score of either 'important' or 'very important'. The least supported recommendations were the use of joint clinics with both paediatric and adult physicians attending and the use of web-based or mobile technologies for communication with the AYA. The most supported recommendation was checking that the AYA is knowledgeable and compliant with their prescribed medication. Qualitative analysis revealed conditional approval for some recommendations. CONCLUSIONS: There was agreement from patients and parents on the importance of the draft recommendations on transitional care for AYA with allergy and/or asthma and their parents. The recommendations now need to be implemented into clinical practice across Europe.

Food immunotherapy practice: Nation differences across Europe, the FIND project.

BACKGROUND: Food allergen immunotherapy (FA-AIT) practice is known to vary globally. This project aims to identify and characterize European centres performing FA-AIT. METHODS: An EAACI task force conducted an online survey to gather relevant information regarding FA-AIT practice and setting-specific resources after reviewing the published literature and congress abstracts throughout Europe. RESULTS: We identified 102 FA-AIT centres in 18 countries; only Spain (n = 39) and France (n = 16) had ≥10 such centres. Overall, most facilities were hospital-based (77.5%), publicly funded (80.4%) and delivered FA-AIT as routine clinical care (80.4%). On average, departments had 3 allergists/paediatric allergists and 2 nurses. Surveyed centres had provided FA-AIT for a median of 9 years [1-24] to a median of 105 [5-2415] patients. The estimated total number of treated patients was 24875, of whom 41.3% received AIT for milk, 34.2% egg, 12.8% peanut and 11.7% other foods. Anaphylaxis to AIT doses requiring over 4-6 h of observation was reported by 70.6% of centres, ICU admissions by 10.8% and eosinophilic esophagitis by 45.1%. Quality of life and sustained unresponsiveness were evaluated in 20.6% and 54.9% of centres, respectively. The main contraindications for food AIT were severe asthma (57%-63%), eosinophilic esophagitis (56%-48%) and age below 5 years (47%-41%). CONCLUSIONS: In Europe, FA-AIT is provided mostly in clinical practice. Significant variation is seen in the number of centres per country, facility characteristics and inclusion/exclusion criteria, and in certain aspects of protocols. Potential inequality in access to AIT has been identified as well as the need for education and guidance for treatment standardization.

Practical protocol of the food allergy committee of the seicap on open oral food challenges to nuts.

Food allergy is rising rapidly among children, and allergy to nuts is one of the most prevalent allergies among them. The category "nuts and seeds" include several plant foods from different botanical families, very different from each other. It is not uncommon to detect co-sensitization to different nuts. However, true co-allergy is less frequent. Up to 80% of patients with positive skin prick tests or specific IgE without true history of reaction who avoid certain nuts, might tolerate them in an Oral Food Challenge (OFC). Although molecular diagnostic techniques help to improve nut allergy diagnosis, OFC still remains the gold standard. For this reason, after reviewing the current bibliography and the recommendations of different allergy societies on standardization of open OFC, the Food Allergy Committee of the Spanish Society of Pediatric Allergy, Asthma and Clinical Immunology (SEICAP) food allergy working group proposed a unified protocol to undertake these OFC, which include preliminary recommendations, unification of total dose, number of doses and interval between doses. Additionally, this group offers an interactive table to facilitate calculation of doses specific to each nut under study.
