Within a few months, the scientific world achieved a great success, developing effective and safe vaccines against COVID-19. Many countries with full access to vaccines have introduced recommendations for the vaccination of not only people who are at risk of developing severe COVID-19, i.e., the elderly and chronically ill, but all members of society, including children aged 12 and above as the currently registered preparations can be used above the said age. However, the use of COVID-19 vaccines in children arouses strong emotions, with their sense being frequently questioned. The aim of the paper was to assess the attitudes of Polish parents with regard to vaccinations against COVID-19 administered to their children. The study was conducted with the use of the authors’ original questionnaire, which was distributed online. The questionnaire was completed 4732 times, and 4432 surveys were qualified for the final analysis. The vast majority of the respondents were women (77.6%), people aged 36–44 (40.3%), with higher education (86.2%) and people living in the city with more than 250,000 inhabitants (48%). The mean age of the study group was 37.5 ± 6.61 years. Out of the studied group, 28.2% of parents are healthcare professionals. The study was conducted prior to the EMA’s decision that permitted the use of BNT162b2 in children. Results: The vast majority of the respondents were mothers, who showed significantly more favorable attitudes toward the vaccinations than fathers. Forty-four percent of parents want to vaccinate their children as soon as possible, while every fourth parent does not want to vaccinate their child at all. Main concerns about the vaccines include concerns that the preparation has not been adequately tested and that it is ineffective, as well as the lack of information concerning potential complications in the future. The main sources of information on childhood vaccinations are the media, including the Internet and television. Vaccination of the pediatric population against COVID-19 raises many emotions and doubts in parents and it is also debated by experts. The decision to vaccinate should rest on child’s parents. Both the individual benefits of protection against COVID-19 and the population benefits of pandemic control must be considered. There is a need for ongoing monitoring of the safety of administering COVID-19 vaccinations in children, as well as for evaluating their effectiveness and benefits in reducing individual risk of severe course of COVID-19 and complications after this disease, and for evaluating the population benefits of vaccines in children.
Asthma is an inflammatory airway disease, and oxidative stress was proven to be involved in its pathogenesis. Apocynin effectively inhibits the main source of reactive oxygen species (ROS)-nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-by blocking its activation. The aim of this study was to investigate the effect of inhaled apocynin on ROS and RNS (reactive nitrogen species) concentration in 14 nonsmoking mild asthmatics. Effects of nebulized apocynin (0.5 mg/mL) were assessed in exhaled breath condensate (EBC) after 30, 60, and 120 minutes, and safety parameters have been analyzed. Apocynin significantly decreased H2O2 concentration in EBC in comparison with placebo after 60 and 120 minutes. Moreover, apocynin significantly reduced NO(-2) concentration 30 and 60 minutes after nebulization and caused a significant decrease of NO(-3) concentration in EBC 60 and 120 minutes after administration, comparing with placebo. No adverse events have been observed throughout the study. This research confirmed anti-inflammatory properties of nebulized apocynin, which might be an effective and safe drug in bronchial asthma.
This evidence-based consensus aims to establish the role of point-of-care lung ultrasound in the management of pneumonia and bronchiolitis in paediatric patients. A panel of thirteen experts form five Polish tertiary pediatric centres was involved in the development of this document. The literature search was done in PubMed database. Statements were established based on a review of full-text articles published in English up to December 2019. The development of this consensus was conducted according to the GRADE (Grading of Recommendations, Assessment, Development and Evaluations)—adopted and Delphi method. Initially, 22 proposed statements were debated over 3 rounds of on-line discussion and anonymous voting sessions. A total of 17 statements were agreed upon, including four statements referring to general issues, nine referring to pneumonia and four to bronchiolitis. For five statements experts did not achieve an agreement. The evidence supporting each statement was evaluated to assess the strength of each statement. Overall, eight statements were rated strong, five statements moderate, and four statements weak. For each statement, experts provided their comments based on the literature review and their own experience. This consensus is the first to establish the role of lung ultrasound in the diagnosis and management of pneumonia and bronchiolitis in children as an evidence-based method of imaging.
Aim Respiratory syncytial virus is the main pathogen responsible for bronchiolitis. Usually, there is no indication to perform diagnostic imaging or run laboratory tests in patients with bronchiolitis since the diagnosis is based on the clinical presentation. Chest radiogram can be useful in severe cases. So far, lung ultrasound has not been considered as an alternative in guidelines for imaging diagnosis of bronchiolitis. The aim of the study was to compare lung ultrasound and chest X-ray findings in children with bronchiolitis. Material and methods In our study we retrospectively compared diagnostic imaging findings in children with confirmed respiratory syncytial virus infection. The study included 23 children aged 2 weeks to 24 months and 3 children older than 24 months. Results Chest X-ray showed lesions in only 4 cases, whereas ultrasound abnormalities were found in 21 patients. Pathologies revealed by chest X-ray were the same for all 4 cases and consisted of an enlarged hilus and peribronchial cuffing. Sonographic lesions included inflammatory consolidations larger than 10 mm in 11 patients, small consolidations (<10 mm diameter) in 8 patients, interstitial syndromes in 6 patients, and alveolar-interstitial syndromes in 11 patients. A small amount of pleural effusion was detected in 3 patients. Conclusions Considering safety, short time of examination, high sensitivity in finding pleural effusion, small consolidations and signs of interstitial infiltrations, transthoracic lung ultrasound may be useful in the diagnosis of bronchiolitis.

M A N U S C R I P T A C C E P T E D ARTICLE IN PRESS AbstractThe imbalance between reactive oxygen species (ROS) synthesis and antioxidants might be involved in the pathogenesis of many inflammatory diseases. NADPH oxidase, an enzyme responsible for ROS production, may represent an attractive therapeutic target to inhibit for the treatment of these diseases.Apocynin is an inhibitor of activation of NADPH oxidase complex present in the inflammatory cells.In double blind, placebo controlled, cross-over study, we investigated the effect of nebulized apocynin on ROS synthesis in 10 nonsmoking healthy volunteers. Apocynin (6 ml of 0.5 mg/ml) was administered by nebulization and its effects on H 2 O 2 , NO 2 -and NO 3 -generation were assessed after 30, 60 and 120 minutes by collecting exhaled breath condensate (EBC) samples using an EcoScreen analyzer. Additionally, respiratory parameters have been evaluated, utilizing spirometry and DLCO. We also analyzed peripheral blood differential counts and NO 2 -serum level, cough scale control and blood pressure as safety parameters. Thus, as apocynin significantly influence ROS concentration, it might have also antiinflammatory properties. As it is safe, it may have a potential to become a drug in airway inflammatory diseases treatment.
The outbreak of the Russian–Ukrainian war contributed to the largest migration movement in the 21st century. As a result, over 3 million refugees, mainly women, children and the elderly, arrived in Poland in a short space of time. Despite the ongoing war, it is important to remember that the COVID-19 pandemic is still present in the world, and before the outbreak of the war, Ukraine was struggling with its fifth wave. Furthermore, Ukraine has one of the lowest vaccination rates in Europe, not exceeding 40%. It is, therefore, reasonable to suspect that the vast majority of migrants have not been vaccinated. This situation may pose a significant epidemiological risk. Therefore, it is necessary to implement appropriate steps to determine the vaccination status of refugees and to supplement the vaccination with both the core and booster doses. In response to these needs, the government of Poland, like many other countries, has made it possible to provide free COVID-19 vaccination to persons fleeing war. In the face of massive migration, the overriding priority should be to ensure adequate medical care for refugees, including free COVID-19 vaccinations. However, it seems that the lack of willingness to vaccinate among Ukrainians is also replicated on migration. It seems reasonable that appropriate steps should be taken to increase awareness and confidence in vaccination, which may ultimately translate into increased vaccination uptake. Analyzing previous experiences, it is advisable to consider that the first step should be to promote vaccination and remind refugees of the possibility of free COVID-19 vaccination. Additionally, refugees should be encouraged to be vaccinated during every contact with health care workers.
influenza is an acute infectious disease of the airways that occurs in every age group. the course of the disease may have a different severity and clinical picture, from asymptomatic to severe with symptoms of respiratory failure. the possibilities of pandemic infections and serious complications throughout the course of influenza distinguish it from other viral respiratory diseases, prompting us to treat it in a special way. Diagnosis of the disease is usually clinical in nature, and additional studies may be helpful in clinically relevant cases. the drug recommended for treatment and chemoprophylaxis is oseltamivir. Clinical benefits are greatest if treatment starts as early as possible, within 48 hours of the first symptoms of influenza. Clinical studies indicate that early treatment with oseltamivir may shorten the duration of the disease and reduce the risk of its complications. Annual influenza vaccination is the most effective method of preventing this disease, and the only contraindication to vaccination is the occurrence of an anaphylactic or other severe allergic reaction after a previous vaccination.
