Meteotsunamis and other anomalous “tidal surge” events in Western Europe in Summer 2022

We investigate occurrences of anomalous tidal activity in coastal waters of north-west Europe during Summer 2022. Sightings of an anomalous “tidal surge” occurred on 18 June 2022 in Wales, followed by similar observations in Ireland, France, and Spain. Several anomalous long-wave events were also reported in south England and Wales in the morning of 19 July 2022. We analyzed surface and high-altitude air pressure fields, and sea level oscillations for both days. Our detailed analysis reveals that the 18 June events were a series of meteotsunamis, propagating over several countries in Western Europe and triggered by localized pressure perturbations, originating within a low-pressure area over the North Atlantic Ocean. A local analysis of the southern coast of Ireland suggests that Proudman resonance was the determinant mechanism that amplified the meteotsunami traveling eastward in the afternoon of 18 June. A similar analysis of the 19 July events suggests that the tidal surge reported in the UK and anomalous signals recorded in Ireland and France were episodes of seiching triggered by infragravity waves, resonated subharmonically by wind waves. Numerical simulations of the 18 June event were performed with Volna-OP2, which solves the non-linear shallow water equations using a finite volume discretization. The influence of the atmospheric wave velocity on the amplification of the sea surface elevation is analyzed

A Patient with 38 Years of Smoking History and Severe Shortness of Breath

Aim: to present a clinical case of post-COVID bronchiolitis in an adult.Key points. A 54-year-old female patient with a long history of smoking was hospitalized in the pulmonology department of the Clinic with a leading complaint of progressive shortness of breath after a COVID-19 infection. The diagnosis was established: bilateral bronchiolitis associated with a new coronavirus infection (SARS-CoV-2 polymerase chain reaction — positive); chronic obstructive pulmonary disease stage II according to GOLD (Global Initiative for Chronic Obstructive Lung Disease), exacerbation. Against the background of the therapy, there was a significant positive dynamics in well-being and in CT-picture of bronchiolitis. The patient was discharged for outpatient follow-up treatment. One of the most common symptoms of post-COVID syndrome is shortness of breath. Diagnosis of bronchiolitis, in which this symptom may be the only one, is difficult, especially in patients with a long history of smoking and the presence of comorbid pulmonary pathology.Conclusion. A clinical case of bilateral bronchiolitis in the framework of the post-COVID syndrome is presented. The key to successful diagnosis of bronchiolitis is a thorough differential analysis of the totality of anamnestic and clinical laboratory data, as well as a characteristic CT pattern

Перспективы применения пробиотических препаратов при острых инфекциях респираторного тракта

Аcute respiratory infection (ARI) is one of the most prevalent diseases worldwide. The disease occurs in any age, so its course could be associated with complications  and poor outcome.  Prevention  and treatment of ARI and complications  are important  problems in clinical practice.  Recent researches of human microbiome  composition  and functions have aroused a great interest to this field in order to prevent ARIs.In this review, the authors discuss non-specific  mechanisms  of human  innate antiviral defense and available data about a role of symbiontic intestinal microf lora for ARI prevention. Typically, main biological properties of probiotic bacteria are considered in the context of modulating effects on the inf lammatory immune response. Published data demonstrated reduction in the risk, severity and duration of ARI under the treatment with probiotic agents both in the children and in adults. The strain-specific effect and potential molecular antiviral mechanisms of probiotics enhancing the antiviral response of symbiontic bacteria are also discussed in the review.Острые  вирусные  инфекции верхних  дыхательных  путей  (ВДП)  являются  одним  из самых  распространенных заболеваний в мире. Заболевание возникает  у лиц всех возрастных  групп и в некоторых случаях может иметь неблагоприятные осложнения и исходы. Одна из приоритетных задач практического здравоохранения состоит в возможности профилактики и лечения  острой респираторной вирусной инфекции и ее осложнений. В представленном обзоре рассмотрены собственные механизмы  неспецифической защиты человеческого организма  от вирусной инфекции. Обобщены  результаты исследований по изучению роли симбионтной кишечной микрофлоры в профилактике острой инфекции ВДП. На основании имеющихся литературных  данных представлены  основные  аспекты биологических свойств пробиотических бактерий,  которые,  как правило,  рассматриваются в контексте  их модулирующего  влияния на воспалительную иммунную реакцию.  Проведен  анализ имеющихся данных о снижении риска возникновения, продолжительности и выраженности симптомов  респираторной инфекции при приеме пробиотических препаратов  (ПБП) как в детском возрасте,  так и во взрослой популяции. Обсуждается  вопрос  штаммоспецифического эффекта  ПБП.  В статье рассмотрены основные  возможные  молекулярные противовирусные механизмы  ПБП, за счет которых симбионтные бактерии усиливают противовирусный ответ

Apophis planetary defense campaign

We describe results of a planetary defense exercise conducted during the close approach to Earth by the near-Earth asteroid (99942) Apophis during 2020 December–2021 March. The planetary defense community has been conducting observational campaigns since 2017 to test the operational readiness of the global planetary defense capabilities. These community-led global exercises were carried out with the support of NASA's Planetary Defense Coordination Office and the International Asteroid Warning Network. The Apophis campaign is the third in our series of planetary defense exercises. The goal of this campaign was to recover, track, and characterize Apophis as a potential impactor to exercise the planetary defense system including observations, hypothetical risk assessment and risk prediction, and hazard communication. Based on the campaign results, we present lessons learned about our ability to observe and model a potential impactor. Data products derived from astrometric observations were available for inclusion in our risk assessment model almost immediately, allowing real-time updates to the impact probability calculation and possible impact locations. An early NEOWISE diameter measurement provided a significant improvement in the uncertainty on the range of hypothetical impact outcomes. The availability of different characterization methods such as photometry, spectroscopy, and radar provided robustness to our ability to assess the potential impact risk
