Screening of otitis media in children with somatic pathology

Catedra Otorinolaringologie, USMF „Nicolae Testemiţanu”Aim of the study was to analyze and compare the incidence and clinical evolution of otitis media (OM) in children with recurrent and chronic somatic pathology and healthy children. Children at the age between 1 and 7 years with no any evident ear problem with recurrent and chronic somatic pathology and healthy children were accepted for screening by Tympanometry and otoscopy every three months during 1 year. Complete audiology assessment and otomicroscopy were carried out for children who failed the screening tests during 6 months. Screening revealed high incidence of OM with effusion in children with recurrent and chronic somatic pathology and it predisposition to chronic evolution. Screening for OM in children with chronic and recurrent somatic pathology determined patients, who need comprehensive treatment, including surgical. In healthy children OM is relatively rare, temporary şi benign condition. Scopul studiului a fost analiza şi comparaţia incidenţei şi evoluţiei clinice OM la copiii cu patologie recidivantă şi cronică a tractului respirator, tractului gastrointestinal în raport cu copiii sănătoşi. Copiii în vârstă de 1 – 7 ani cu patologia somatică recidivantă şi cronică fără patologia auriculară cunoscută au fost acceptaţi pentru screening cu timpanometrie şi otoscopie fiecare 3 luni pe parcursul anului. Examenul audiologic complet şi otomicroscopia au fost efectuate pentru copiii care au avut rezultate positive pe parcursul a 6 luni. Screeningul a evidenţiat prevalenţa înalta a OM exsudative la copiii cu patologie somatică recidivantă şi cronică şi predispoziţia patologiei pentru evoluţia cronică. Screeningul pentru OM la copiii cu patologie somatică recidivantă şi cronică determină pacientii, care au nevoie de tratament intensiv adecvat, incluzând chirurgical. La copiii sănătoşi OM este proces relativ rar, temporar şi benign

Joint Observation of the Galactic Center with MAGIC and CTA-LST-1

MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes (IACTs), designed to detect very-high-energy gamma rays, and is operating in stereoscopic mode since 2009 at the Observatorio del Roque de Los Muchachos in La Palma, Spain. In 2018, the prototype IACT of the Large-Sized Telescope (LST-1) for the Cherenkov Telescope Array, a next-generation ground-based gamma-ray observatory, was inaugurated at the same site, at a distance of approximately 100 meters from the MAGIC telescopes. Using joint observations between MAGIC and LST-1, we developed a dedicated analysis pipeline and established the threefold telescope system via software, achieving the highest sensitivity in the northern hemisphere. Based on this enhanced performance, MAGIC and LST-1 have been jointly and regularly observing the Galactic Center, a region of paramount importance and complexity for IACTs. In particular, the gamma-ray emission from the dynamical center of the Milky Way is under debate. Although previous measurements suggested that a supermassive black hole Sagittarius A* plays a primary role, its radiation mechanism remains unclear, mainly due to limited angular resolution and sensitivity. The enhanced sensitivity in our novel approach is thus expected to provide new insights into the question. We here present the current status of the data analysis for the Galactic Center joint MAGIC and LST-1 observations

The immunological status in recurrent inflammation of maxillary and ethmoid sinuses in early childhood

IMSP Spitalul Clinic Republican pentru Copii “Em.Coţaga” Universitatea de Stat de Medicină şi Farmacie „Nicolae Testemiţanu”In this article we presented the results of immunological examination of children in the first three years of life with recurrent sinusites. The changes in immunological status which were revealed in cases with sinusitis, were the reason for immunotherapy. În articol sunt prezentate rezultatele examinărilor imunologice la copii de vîrstă fragedă cu maxilo-etmoidite recidivante. Modificările în sistemul imun constatate în această afecţiune justifică utilizarea în tratamentul complex a terapiei imunocorectoare

Contemporary aspects of endoscopic surgical treatment of hypertrophies of adenoid tissue in children

Catedra Otorinolaringologie, USMF "Nicolae Testemiţanu"Modern technologies make it possible to improve the quality of medical surgery. Adenoidectomy under endoscopic control provides full view of the surgical field. This gives the possibility to completely remove lymphoid tissue in the nasopharynx with minimal traumatic effect. It also makes it possible to simultaneously detect and correct concomitant pathologies of adjacent structures. Implementarea tehnologiilor moderne în medicină facilitează îmbunătăţirea calităţii intervenţiilor chirurgicale. Adenoidectomia sub controlul endoscopic asigură o vizualizare completă a cîmpului operator, cea ce oferă posibilitatea înlăturării complete a ţesutului limfoid din nazofaringe cu un efect traumatic minimal. În acelaşi timp face posibil de a depista şi de a corecta simultan patologiile concomitente a structurilor adiacente

Spintronic Physical Reservoir for Autonomous Prediction and Long-Term Household Energy Load Forecasting

With the growing use of artificial neural networks (ANNs) in temporal data processing tasks, the cost of training of complex ANNs is an increasing concern. Physical reservoir computing (RC), a variation of recurrent neural networks (RNNs), obviates the need for most data intensive matrix vector multiplication in the recurrent layer by evolving the RC’s internal states with inherent nonlinear dynamics and short-term memory. In this study, we show that magnetic skyrmion confined to a fixed geometry forming the soft layer of a magnetic tunnel junction (MTJ) can work as a RC and perform autonomous long-term prediction of temporal data. Our proposed skyrmion reservoir allows for manipulation of spin dynamics with ultra energy efficient voltage controlled magnetic anisotropy (VCMA) modulation method. Furthermore, the boundary effect on the skyrmion from the geometric edges provides the necessary consistency property of the reservoir. We employ our proposed reservoir for the modeling and prediction of chaotic time series such as Mackey-Glass and dynamic time-series data, such as household building energy loads. For autonomous run, the predicted output is fed to the input of the reservoir. By comparing our spintronic physical RC approach with energy load forecasting algorithms, such as long short-term memory (LSTM) and RNNs, we conclude that the proposed framework presents good performance in achieving high predictions accuracy, while also requiring low memory and energy both of which are at a premium in hardware resource and power constrained edge applications. Further, the proposed approach is shown to require very small training datasets and at the same time being at least 16 times more energy efficient compared to the sequence to sequence LSTM for accurate household load predictions. Higher endurance, fast processing and well-established technology (i.e., MTJ) to integrate with CMOS technology makes such spintronic reservoir attractive over other emergent physical reservoirs
