Alergia alimentar autodeclarada em idosos no Brasil: prevalência e características clínicas ­ Protocolo de estudo / Self-reported food allergy among older Brazilians: prevalence and clinical characteristics ­ a study protocol

Nas últimas décadas tem se observado um aumento expressivo na prevalência de alergia alimentar (AA), com frequência estimada em adultos de 3% a 8%, sendo ainda mais relevante quando se avalia a AA autodeclarada (variação de 3% a 35%). Entretanto, são poucos os dados publicados sobre a prevalência de AA em idosos, e no Brasil tais dados são inexistentes. O objetivo principal deste protocolo de estudo é conhecer a prevalência de AA autodeclarada em idosos (≥ 60 anos) brasileiros. Trata-se de estudo epidemiológico transversal que utiliza questionário padronizado e validado para a língua portuguesa. Entre os vários aspectos investigados, serão avaliados quais alimentos e sintomas são os mais relacionados à AA nestes indivíduos. Os dados obtidos serão transcritos a planilha Excel para realização da análise estatística. A obtenção dessas informações permitirá compará-las às existentes, assim como estabelecer planos de abordagem destes pacientes.

In recent decades, there has been a significant increase in the prevalence of food allergies, reaching an estimated frequency of 3% to 8% in adults and even higher in self-reports (from 3% to 35%). However, published data on the prevalence of food allergies among older adults are scarce, and in Brazil they are non-existent. The main objective of this study was to investigate the prevalence of self-reported food allergy among older Brazilians (≥ 60 years). This cross-sectional epidemiological study protocol involves a questionnaire that was developed, standardized, and validated in Portuguese. The investigated aspects will include the foods and symptoms most commonly associated with food allergy in this population. The data will be input into an Excel spreadsheet for statistical analysis. Obtaining this data will allow comparison of the results with previous data and help establish treatment plans for these patients.

Incidental chest findings on coronary CT angiography: a pictorial essay and management proposal.

Many health systems have been using coronary CT angiography (CCTA) as a first-line examination for ischaemic heart disease patients in various countries. The rising number of CCTA examinations has led to a significant increase in the number of reported incidental extracardiac findings, mainly in the chest. Pulmonary nodules are the most common incidental findings on CCTA scans, as there is a substantial overlap of risk factors between the population seeking to exclude ischaemic heart disease and those at risk of developing lung cancer (i.e., advanced age and smoking habits). However, most incidental findings are clinically insignificant and actively pursuing them could be cost-prohibitive and submit the patient to unnecessary and potentially harmful examinations. Furthermore, there is little consensus regarding when to report or actively exclude these findings and how to manage them, that is, when to trigger an alert or to immediately refer the patient to a pulmonologist, a thoracic surgeon or a multidisciplinary team. This pictorial essay discusses the current literature on this topic and is illustrated with a review of CCTA scans. We also propose a checklist organised by organ and system, recommending actions to raise awareness of pulmonologists, thoracic surgeons, cardiologists and radiologists regarding the most significant and actionable incidental findings on CCTA scans.

Incidental findings on lung cancer screening: pictorial essay and systematic checklist.

Lung cancer screening (LCS) programs are increasing worldwide. Incidental findings (IFs) on LCS are defined as low-dose CT findings unrelated to the primary purpose of identifying lung cancer. Most IFs on LCS are benign and clinically insignificant but are being increasingly recognized, and some require urgent referral for further diagnostic workup. Other findings are expected and are known as smoking-related comorbidities, including COPD, cardiovascular disease, emphysema, and interstitial lung disease, and their diagnosis can have a significant impact on patient prognosis. The purpose of this pictorial essay is to illustrate the most common IFs on LCS, organized by organ. We will discuss the current literature on IFs on LCS, focusing on their prevalence, appropriate communication, and triggering of clinical pathway systems.

RESUMO Muitos sistemas de saúde têm utilizado a angiotomografia coronariana (ATC) como exame de primeira linha para pacientes com doença cardíaca isquêmica em diversos países. O crescente número de exames de ATC tem levado a um aumento significativo do número de relatos de achados extracardíacos incidentais, principalmente no tórax. Nódulos pulmonares são os achados incidentais mais comuns nas imagens de ATC, pois há uma substancial sobreposição de fatores de risco entre a população que busca a exclusão de doença cardíaca isquêmica e aqueles em risco de desenvolver câncer de pulmão (por exemplo, idade avançada e tabagismo). No entanto, a maioria dos achados incidentais é clinicamente insignificante e seu seguimento ativo pode ter um custo proibitivo e submeter o paciente a exames desnecessários e potencialmente prejudiciais. Além disso, há pouco consenso sobre quando relatar ou ativamente excluir esses achados e como manejá-los, ou seja, quando acionar um alerta ou imediatamente encaminhar o paciente para um pneumologista, um cirurgião torácico ou uma equipe multidisciplinar. Este ensaio pictórico discute a literatura atual sobre esse tópico e é ilustrado com uma revisão de imagens de ATC. Também propomos uma lista de verificação organizada por órgão e sistema, recomendando ações para a conscientização de pneumologistas, cirurgiões torácicos, cardiologistas e radiologistas sobre os achados incidentais mais significativos e acionáveis nas imagens de ATC.

RESUMO Os programas de rastreamento de câncer de pulmão (RCP) estão aumentando em todo o mundo. Achados incidentais (AI) no RCP são achados de TC de baixa dose sem relação com o propósito principal de identificar câncer de pulmão. A maioria dos AI no RCP é benigna e clinicamente insignificante, mas os AI estão sendo cada vez mais reconhecidos, e alguns requerem encaminhamento urgente para investigação diagnóstica adicional. Outros achados são esperados e conhecidos como comorbidades relacionadas ao tabagismo, tais como DPOC, doença cardiovascular, enfisema e doença pulmonar intersticial, e seu diagnóstico pode ter um impacto significativo no prognóstico do paciente. O propósito deste ensaio pictórico é ilustrar os AI mais comuns no RCP, organizados por órgão/sistema. Discutiremos a literatura atual a respeito de AI no RCP, com foco em sua prevalência, comunicação apropriada e desencadeamento de procedimentos clínicos.

Adverse reactions to foods and food allergy: development and reproducibility of a questionnaire for clinical diagnosis.

Objective. To develop a questionnaire as a screening tool for adverse reactions to foods in children and to assess the technical reproducibility by test-retest. Methods. Reproducibility of the questionnaire was performed by the literature review, preparing the preliminary questionnaire, peer review, pretest, and retest analysis. The study of the test-retest reproducibility was cross-sectional and descriptive. Kappa coefficient was used to study the reproducibility of the questionnaire. The sample consisted of 125 2-4 year-old children from 15 daycare centers in Recife, Brazil, and interviews with parents or caregivers were used to collect data. Results. From the total children, sixty-three were boys (50.4%), forty-six were two years old (36.8%), forty-seven were three years old (37.6%), and thirty-two were four years old (25.6%). Forty caregivers reported that their child had health problems with food. Most frequently reported offending foods were milk, peanuts, shrimp, and chocolate. Nine questions showed a good Kappa index (≥0,6). Conclusions. The questionnaire used needs to be resized and reshaped on the basis of the issues with good internal consistency and reproducibility. The use of a validated and reproducible questionnaire in the children represents an important contribution towards assessing an eventual rise in overt food allergy.
