RESUMO

INTRODUCTION: The COVID pandemic has had a high psychological impact on healthy populations. Increased levels of perceived stress, depression, and insomnia are expected, especially in people with pre-existing medical conditions, such as asthma and chronic obstructive pulmonary disease (COPD), who seem to be particularly vulnerable. However, the difference in psychological distress frequency between asthma and COPD patients is unknown. OBJECTIVE: To compare the prevalence of depression, perceived stress related to COVID, post-traumatic stress, and insomnia in asthma and COPD patients at a pulmonology clinic in Santa Marta, Colombia. METHODS: A cross-sectional study was designed. The patients were contacted by telephone. An electronic link was sent to those who accepted. The questionnaire asked for perceived stress related to COVID-19, post-traumatic stress symptoms, depressive symptoms, and insomnia risk. RESULTS: 148 asthma patients and 144 COPD patients participated in, between 18 and 96 years. The prevalence of high COVID-19 perceived stress was 10.6% (n = 31); post-traumatic stress risk, 11.3% (n = 33); depression risk, 31.5% (n = 92); and insomnia risk, 57.7% (n = 169). No significant differences were found between asthma and COPD in indicators of psychological distress. CONCLUSIONS: Asthma and COPD patients present similar frequencies of depression risk, COVID-19 perceived stress, post-traumatic stress risk, and insomnia risk during the Colombian lockdown. It is essential to evaluate and manage psychological distress among asthma and COPD patients. It can reduce the risk of exacerbation and improve the quality of life.

RESUMO

BACKGOUN: Asthma and dry eye disease are common clinical diseases. Studies have shown that asthma is related to dry eye, but there is no high-quality evidence-based medical evidence. METHOD: This protocol and final study will be conducted in accordance with the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols 2015 statement. We will search PubMed, EMBASE, ISI Web of Science, China National Knowledge Infrastructure for all relevant literature published from their inception up to August 1, 2020. Literature search, data extraction, and quality assessment will be carried out independently by two researchers, and a third researcher will resolve differences when necessary. The association between dry eye disease and asthma will indicate as odds ratio with 95% confidence interval and statistically analyzed using RevMan 5.3 software. If the studies included have high heterogeneity, we will conduct sensitivity analysis and subgroup analysis. RESULTS: The protocol is intended to guide a meta-analysis aimed at identifying and quantifying the association between asthma and dry eye disease.

RESUMO

Asthma is a complex disease that often starts in childhood. Genomic and environmental factors as well as aberrant immune maturation early in life can contribute to the onset of disease, with great disparity over time and geographical regions. Epidemiological studies have scrutinised environmental exposures and attempted to translate these exposures into prevention strategies. Some approaches for patients with asthma have been successful (eg, smoking ban, the Finnish Asthma Programme), and primary prevention of wheeze in pre-school children (age 0-5 years) by the supplementation of vitamin D or fish oil, or both, to pregnant women seems promising. Several recent prevention initiatives are based on strong asthma-protective environmental microbial exposures associated with traditional rural lifestyles. Preclinical studies with various bacterial lysates, bacterial and dietary metabolites, or helminthic compounds have yielded promising results that await translation into clinical practice. Given the immense societal and individual burden of asthma, there is an urgent need to further develop novel strategies to eradicate the disease.

RESUMO

PURPOSE: Climate and lifestyle changes increase an individual's susceptibility to various allergens and also the incidence of allergic diseases. We aimed to examine the changes in sensitization rate for aeroallergens over a 10-year period in Korean children. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 4493 children who visited the allergy clinic at a tertiary hospital in Korea for allergic rhinitis or asthma from January 2009 to December 2018. The serum specific immunoglobulin E (IgE) levels were measured to confirm the sensitization against Dermatophagoides farinae (D. farinae), Alternaria, weed and tree pollen mixtures, as well as cat and dog dander through ImmunoCAP test. RESULTS: D. farinae was the most common sensitizing aeroallergen (45.9%) during the 10-year span. The sensitization rate for tree pollen mixture (p for trend <0.001), weed pollen mixtures (p for trend <0.001), dog dander (p for trend=0.025), and cat dander (p for trend=0.003) showed ascending trends during the 10-year study period. Furthermore, the sensitization rate for multiple allergens (≥2) in 2018 increased significantly compared to that in 2009 (p for trend=0.013). Compared with children without sensitization to D. farinae, those with sensitization to D. farinae showed higher sensitization rates to other aeroallergens (p for interaction <0.001). CONCLUSION: Children's sensitization rate to cat and dog dander and weed and tree pollen mixtures significantly increased during the 10-year period in Korea. Children with sensitization to D. farinae are likely to be sensitized to other aeroallergens as well.

RESUMO

Potential long-lasting adverse effects of child maltreatment have been widely reported, although little is known about the distinctive long-term impact of differing types of maltreatment. Our objective for this special article is to integrate findings from the Mater-University of Queensland Study of Pregnancy, a longitudinal prenatal cohort study spanning 2 decades. We compare and contrast the associations of specific types of maltreatment with long-term cognitive, psychological, addiction, sexual health, and physical health outcomes assessed in up to 5200 offspring at 14 and/or 21 years of age. Overall, psychological maltreatment (emotional abuse and/or neglect) was associated with the greatest number of adverse outcomes in almost all areas of assessment. Sexual abuse was associated with early sexual debut and youth pregnancy, attention problems, posttraumatic stress disorder symptoms, and depression, although associations were not specific for sexual abuse. Physical abuse was associated with externalizing behavior problems, delinquency, and drug abuse. Neglect, but not emotional abuse, was associated with having multiple sexual partners, cannabis abuse and/or dependence, and experiencing visual hallucinations. Emotional abuse, but not neglect, revealed increased odds for psychosis, injecting-drug use, experiencing harassment later in life, pregnancy miscarriage, and reporting asthma symptoms. Significant cognitive delays and educational failure were seen for both abuse and neglect during adolescence and adulthood. In conclusion, child maltreatment, particularly emotional abuse and neglect, is associated with a wide range of long-term adverse health and developmental outcomes. A renewed focus on prevention and early intervention strategies, especially related to psychological maltreatment, will be required to address these challenges in the future.

RESUMO

There are limited data about the coexistence of asthma and the Coronavirus disease-2019 (COVID-19). The COVID-19 pandemic is a new disease for the whole world. In this study, we aimed to examine the published case series with the COVID-19 and asthma coexistence, by reviewing existing studies and other publications. We discussed the suggestions of guidelines such as The Global Initiative for Asthma (GINA), The National Institute for Health and Care Excellence (NICE), and the Canadian Respiratory Guideline about the management of asthma during the COVID-19 pandemic and the experiences of different countries. We analyzed the publications, reports, and expert opinions about asthma and COVID-19, that were released and expressed from the onset of the disease in Wuhan. In this review, we aimed to summarize the approach to patients with asthma during the pandemic and to make recommendations concerning it.

RESUMO

Atopic dermatitis is a common inflammatory skin disorder characterised by recurrent eczematous lesions and intense itch. The disorder affects people of all ages and ethnicities, has a substantial psychosocial impact on patients and relatives, and is the leading cause of the global burden from skin disease. Atopic dermatitis is associated with increased risk of multiple comorbidities, including food allergy, asthma, allergic rhinitis, and mental health disorders. The pathophysiology is complex and involves a strong genetic predisposition, epidermal dysfunction, and T-cell driven inflammation. Although type-2 mechanisms are dominant, there is increasing evidence that the disorder involves multiple immune pathways. Currently, there is no cure, but increasing numbers of innovative and targeted therapies hold promise for achieving disease control, including in patients with recalcitrant disease. We summarise and discuss advances in our understanding of the disease and their implications for prevention, management, and future research.

RESUMO

Background: Atopy is poorly researched in HIV children living in the developing countries. There is no previous report on this subject in Nigeria and this pioneering study is undertaken to create an awareness of the burden of this disease among health practitioners. Aims: The aim of this study was to document the atopic diseases present among HIV-infected children attending the antiretroviral (ARV) clinic of a Nigerian tertiary hospital. Methods: Information was obtained from consecutive consenting caregiver/HIV-infected child attending the pediatric ARV clinic, by the use of a proforma specifically designed for the study. The data obtained were analyzed using Statistical Package for the Social Sciences (SPSS) software program, version 16.0. Results: Seventy patients were studied and their ages ranged between 2 and 17 years. These 70 were constituted by 34 (48.6%) boys and 36 (51.4%) girls. Ten (14.3%) of the 70 studied, had atopic diseases. Nine (12.9%) patients had allergic conjunctivitis and 1 (1.4%) had allergic rhinitis. The single patient with allergic rhinitis also had bronchial asthma. No case of atopic eczema, or food allergy was recorded. Atopic disease conditions were more commonly recorded among the male sex and those whose parents have atopic diseases (P < 0.05). Atopic diseases were also more common among children without advanced HIV diseases and those with eosinophilia. Cosmetic and psychological embarrassment from eye discoloration and itching were the negative impacts on the quality of living. Conclusion: Allergic conjunctivitis is common in HIV-infected Nigerian children. Atopies are more common in boys and children with parental atopies.

RESUMO

The potential detrimental effects of steroids on the immune system to fight viral infections had always been a concern for patients on long term steroids in chronic conditions. A recent warning from WHO on systemic corticosteroid use amid COVID-19 raised suspicion among public and healthcare professionals regarding the safety of steroid use during the SARS-CoV-2 pandemic. The corticosteroids (inhaled and oral) are commonly prescribed in the management of asthma and COPD patients and any unsolicited changes in medications use may lead to potentially severe exacerbations and may risk patient lives. This article provides a critical review of clinical evidence and offers a detailed discussion on the safety and efficacy of corticosteroids in asthma and COPD patients, both with and without COVID-19.

RESUMO

The purpose of this study was to evaluate the association between oral health and asthma/allergic rhinitis/atopic dermatitis in a large representative Korean adolescent population.A total of 136,027 participants (aged 12-18 years old) were selected from the Korea Youth Risk Behavior Web-based Survey 2014 to 2015. The subjects' history of asthma, allergic rhinitis, and atopic dermatitis was determined by inquiring whether they had been diagnosed by a medical doctor within the previous 12 months or throughout life. Participants were asked if they had experienced the following 6 symptoms regarding oral health in the past 12 months: "chipped or broken tooth," "toothache when eating or drinking," "throbbing and sore tooth," "sore and bleeding gums," "pain in the tongue or inside the cheeks," and "unpleasant breath." The participants were divided into 3 groups according to the number of oral health-related symptoms as follows: good oral health (symptoms = 0), moderate oral health (symptoms = 1), and poor oral health (symptoms = 2-6). Multiple logistic regression analyses calculated the adjusted odds ratios (aORs) with 95% confidence intervals (CIs) for asthma/allergic rhinitis/atopic dermatitis within the past 12 months and throughout life among groups with oral health-related symptom groups.Older age, female sex, fewer days of physical activity, lower parental economic level, lower parental education level, smoking, and frequent alcohol consumption were associated with poor oral health (each P < .001). The aORs for asthma/allergic rhinitis/atopic dermatitis were 1.48 (95% CI = 1.34-1.63, P < .001), 1.42 (95% CI = 1.36-1.47, P < .001), and 1.35 (95% CI = 1.28-1.43, P < .001), respectively, in the poor oral health group compared to the good oral health group.Poor oral health was significantly correlated with the prevalence of asthma/allergic rhinitis/atopic dermatitis within the past 12 months and throughout life in Korean adolescents. Based on our comparative data, oral health-related education may be considered to adolescents with allergic disease for good oral health.

RESUMO

INTRODUCTION: There is evidence that caesarean section (CS) is associated with increased risk of childhood obesity, asthma, and coeliac disease. The gut microbiota of CS-born babies differs to those born vaginally, possibly due to reduced exposure to maternal vaginal bacteria during birth. Vaginal seeding is a currently unproven practice intended to reduce such differences, so that the gut microbiota of CS-born babies is similar to that of babies born vaginally. Our pilot study, which uses oral administration as a novel form of vaginal seeding, will assess the degree of maternal strain transfer and overall efficacy of the procedure for establishing normal gut microbiota development. METHODS AND ANALYSIS: Protocol for a single-blinded, randomized, placebo-controlled pilot study of a previously untested method of vaginal seeding (oral administration) in 30 CS-born babies. A sample of maternal vaginal bacteria is obtained prior to CS, and mixed with 5 ml sterile water to obtain a supernatant. Healthy babies are randomized at 1:1 to receive active treatment (3 ml supernatant) or placebo (3 ml sterile water). A reference group of 15 non-randomized vaginal-born babies are also being recruited. Babies' stool samples will undergo whole metagenomic shotgun sequencing to identify potential differences in community structure between CS babies receiving active treatment compared to those receiving placebo at age 1 month (primary outcome). Secondary outcomes include differences in overall gut community between CS groups (24 hours, 3 months); similarity of CS-seeded and placebo gut profiles to vaginally-born babies (24 hours, 1 and 3 months); degree of maternal vaginal strain transfer in CS-born babies (24 hours, 1 and 3 months); anthropometry (1 and 3 months) and body composition (3 months). ETHICS AND DISSEMINATION: Ethics approval by the Northern A Health and Disability Ethics Committee (18/NTA/49). Results will be published in peer-reviewed journals and presented at international conferences. REGISTRATION: Australian New Zealand Clinical Trials Registry (ACTRN12618000339257).

RESUMO

Poor indoor air quality in scholar environments have been frequently reported, but its impact on respiratory health in schoolchildren has not been sufficiently explored. Thus, this study aimed to evaluate the associations between children's exposure to indoor air pollution (IAP) in nursery and primary schools and childhood asthma. Multivariate models (independent and multipollutant) quantified the associations of children's exposure with asthma-related health outcomes: reported active wheezing, reported and diagnosed asthma, and lung function (reduced FEV1/FVC and reduced FEV1). A microenvironmental modelling approach estimated individual inhaled exposure to major indoor air pollutants (CO2, CO, formaldehyde, NO2, O3, TVOC, PM2.5 and PM10) in nursery and primary schools from both urban and rural sites in northern Portugal. Questionnaires and medical tests (spirometry pre- and post-bronchodilator) were used to obtain information on health outcomes and to diagnose asthma following the newest international clinical guidelines. After testing children for aeroallergen sensitisation, multinomial models estimated the effect of exposure to particulate matter on asthma in sensitised individuals. The study population were 1530 children attending nursery and primary schools, respectively 648 pre-schoolers (3-5 years old) and 882 primary school children (6-10 years old). This study found no evidence of a significant association between IAP in nursery and primary schools and the prevalence of childhood asthma. However, reported active wheezing was associated with higher NO2, and reduced FEV1 was associated with higher O3 and PM2.5, despite NO2 and O3 in schools were always below the 200 µg m-3 threshold from WHO and National legislation, respectively. Moreover, sensitised children to common aeroallergens were more likely to have asthma during childhood when exposed to particulate matter in schools. These findings support the urgent need for mitigation measures to reduce IAP in schools, reducing its burden to children's health.

RESUMO

OBJECTIVE: To identify risk factors (air pollution and family related) for the onset of asthma and persistent wheezing in children. DESIGN: Nationwide case-control study. SETTING: Denmark. PARTICIPANTS: All Danish children born from 1997 to 2014 and followed for asthma onset and persistent wheezing from age 1 year to 15 years. MAIN OUTCOME MEASURE: Onset of asthma and persistent wheezing. RESULTS: A higher incidence of asthma was found in children of parents with asthma (adjusted hazard ratio 2.29 (95% confidence interval 2.22 to 2.35) and mothers who smoked during pregnancy (1.20, 1.18 to 1.22), whereas a lower incidence was found in children of parents with high educational attainment (0.72, 0.69 to 0.75) and high incomes (0.85, 0.81 to 0.89). Exposure to particulate matter ≤2.5 µm (PM2.5) and ≤10 µm (PM10) and nitrate was associated with an increased risk of asthma and persistent wheezing, with hazard ratios per 5 µg/m3 increase in pollutant concentrations 1.05 (1.03 to 1.07) for PM2.5, 1.04 (1.02 to 1.06) for PM10, and 1.04 (1.03 to 1.04) for nitrogen dioxide. Only the positive association of PM2.5 with asthma and persistent wheezing remained robust across the different models and in sensitivity analyses. CONCLUSIONS: The findings of this study suggest that children exposed to higher levels of PM2.5 are more likely to develop asthma and persistent wheezing than children who are not exposed. Other risk factors associated with these outcomes were parental asthma, parental education, and maternal smoking during pregnancy.

RESUMO

Objective: To understand the prevalence of asthma and its variation over time in children aged 0-14 years in China. Methods: The studies on the prevalence of asthma in children in China were systematically retrieved from China National Knowledge Infrastructure (CNKI), WanFang Data, China Science and Technology Journal Database (VIP) and PubMed databases. The search time was up to June 2019, and the study site was located in the asthma surveillance cities. Random effect model was used to calculate the combined prevalence of asthma and its 95% confidence interval (CI). The subgroup analysis was conducted by period, sex and region. All analyses were performed by using Stata 15.1 and R Studio software. Results: Among 2 624 articles, 67 met the eligibility criteria, and the survey time was from 1989 to 2015. A total of 1 661 076 children were involved and 40 737 asthma cases were confirmed from 26 provinces, municipalities and autonomous regions. The prevalence of asthma varied greatly among different studies, ranging from 0.5% to 9.82%. Meta-analysis showed that the combined prevalence of asthma in Chinese children aged 0-14 was 2.6% (95%CI: 2.1%-3.1%), about 3.2% (95%CI: 2.6%-3.8%) for boys and 1.9% (95%CI: 1.6%-2.3%) for girls. The subgroup analysis showed a significant variation of the prevalence over different years, genders and regions (P<0.05). The prevalence of asthma in boys was consistently higher than that of girls. The overall prevalence of asthma showed an upward trend. Before 2010, the prevalence of asthma in the eastern region was higher than that in the central and western regions. The prevalence of asthma across regions showed a significant change and the prevalence of asthma in the central region was significantly higher than that in the eastern and western regions from 2010 to 2015 (P<0.05). Conclusion: The asthma prevalence of children aged 0-14 in China is generally increasing, and the prevalence rate of boys is higher than that of girls. The prevalence rate in the central region is significantly higher than that in the eastern region from 2010 to 2015, suggesting that those regions should strengthen the early prevention and intervention of asthma and implement a sex-specific information dissemination strategy.

RESUMO

Polygenic scores (PGS) have been widely used to predict disease risk using variants identified from genome-wide association studies (GWAS). To date, most GWAS have been conducted in populations of European ancestry, which limits the use of GWAS-derived PGS in non-European ancestry populations. Here, we derive a theoretical model of the relative accuracy (RA) of PGS across ancestries. We show through extensive simulations that the RA of PGS based on genome-wide significant SNPs can be predicted accurately from modelling linkage disequilibrium (LD), minor allele frequencies (MAF), cross-population correlations of causal SNP effects and heritability. We find that LD and MAF differences between ancestries can explain between 70 and 80% of the loss of RA of European-based PGS in African ancestry for traits like body mass index and type 2 diabetes. Our results suggest that causal variants underlying common genetic variation identified in European ancestry GWAS are mostly shared across continents.
