Demerdzieva A, pop-Jordanova N. AN OVERVIEW OF PEDIATRIC APPROACHES TO CHILD WITH DEVELOPMENTAL DELAY ESPECIALLY IF THERE IS SUSPICION OF ASD IN FIRST FEW YEARS OF LIFE. CONTRIBUTIONS. Sec. of Med. Sci., XLIII 3, 2022 [Internet]. 2022. Publisher's VersionAbstract
To be a pediatrician means that one encounters many serious childhood health problems and one finds many ways to help families cope with these problems. Symptoms in children can be discrete, and the responsibility of the pediatrician to distinguish normal development from pathological. We are facing a new era in the developmental assessment of children. A cluster of neurodevelopmental disorders includes ASD (autism spectrum disorder) and ADHD (attention deficit hyperactivity disorder). Parents often do not recognize the problem on time. Generally, their first concern is speech delay, leading to the suspicion of hearing problems. Therefore, it is very important to obtain objective anamnestic information and for the child to undergo a careful physical examination, a neurophysiological assessment, and metabolic and genetic testing. The etiology usually is multifactorial: genetic, epigenetic, and non-genetic factors act in combination through various paths. Most children seem to have typical neurodevelopment during first their year. It was found that approximately one-third of children with ASD lose some skills during the preschool period, usually speech related, but sometimes also non-verbal communication, social or play skills. In conclusion we must say that it is very important to recognize the early signs of ASD and any kind of other developmental delay and to start with early intervention. Clinical pediatricians tend to correlate clinical manifestations and biological underpinnings related to neurodevelopmental disorder, especially ASD. Therefore, better treatment possibilities are needed.

Communicating safety information to patients and healthcare professionals is a public health responsibility and is essential for achieving the objectives of pharmacovigilance in terms of promoting the rational, safe and effective use of medicines, preventing harm from adverse reactions, minimising risks and contributing to the protection of patients and public health. The main emphasis of this article is on direct healthcare professional communication (DHPC). Countries of interest are Macedonia, Serbia, Bosnia & Herzegovina, Montenegro, Albania and Kosovo. Safety communication should deliver relevant, clear, accurate and consistent messages and reach the right audiences at the right time for them to take appropriate action. Readers will get an indepth look at regulation compliance from the emerging markets within country-specific environments.
Jeremy Manry, Paul Bastard AGTLVJRQPEMH-H. The risk of COVID-19 death is much greater and age-dependent with type I IFN autoantibodies. Proc Natl Acad Sci U S A [Internet]. 2022. Publisher's VersionAbstract
SARS-CoV-2 infection fatality rate (IFR) doubles with every five years of age from childhood onward. Circulating autoantibodies neutralizing IFN-α, IFN-ω, and/or IFN-β are found in ~20% of deceased patients across age groups. In the general population, they are found in ~1 % of individuals aged 20–70 years and in >4% of those >70 years old. With a sample of 1,261 deceased patients and 34,159 uninfected individuals, we estimated both IFR and relative risk of death (RRD) across age groups for individuals carrying autoantibodies neutralizing type I IFNs, relative to non-carriers. For autoantibodies neutralizing IFN-α2 or IFN-ω, the RRD was 17.0[95% CI:11.7–24.7] for individuals under 70 years old and 5.8[4.5–7.4] for individuals aged 70 and over, whereas, for autoantibodies neutralizing both molecules, the RRD was 188.3[44.8–774.4] and 7.2[5.0–10.3], respectively. IFRs increased with age, from 0.17%[0.12–0.31] for individuals <40 years old to 26.7%[20.3–35.2] for those ≥80 years old for autoantibodies neutralizing IFN-α2 or IFN-ω, and from 0.84%[0.31–8.28] to 40.5%[27.82–61.20] for the same two age groups, for autoantibodies neutralizing both molecules. Autoantibodies against type I IFNs increase IFRs, and are associated with high RRDs, particularly those neutralizing both IFN-α2 and -ω. Remarkably, IFR increases with age, whereas RRD decreases with age. Autoimmunity to type I IFNs appears to be second only to age among common predictors of COVID-19 death.

Shape-Controlled Electroless Plating of Hetero-Nanostructures: AgCu-and AgNi-Decorated Ag Nanoplates on Carbon Fibers as Catalysts for the Oxygen Evolution Reaction. ACS Applied Nano Materials [Internet]. 2022;5(8):10348-10357. Publisher's VersionAbstract
This study addresses the potential of combining multiple electroless plating reactions for homogeneous decoration of three-dimensional carbon fibers (CFs) with shape-controlled AgNi and AgCu bimetallic nanostructures. Morphology, crystal structure, and composition of the obtained bimetallic nanostructures were systemically examined by various spectroscopic and microscopic techniques including scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The electrocatalytic performance of the synthesized materials was investigated for the oxygen evolution reaction (OER). AgCu and AgNi bimetallic surfaces showed superior activity and stability compared to pristine Ag, Ni, or Cu. These observed enhancements on the bimetallic nanostructures are attributed to the synergistic effect between the elements present. AgNi nanoplate-decorated CFs exhibited the highest activity toward OER, which is attributed to the key role of Ag in stabilizing and increasing the number of β-NiOOH surface sites, which are the most relevant OER-active Ni species.
Panev K, Zdraveva A. The Status of Influencers in the Macedonian Legal System. Yearbook 2021 [Internet]. 2022;XI(1857-8713):59-66. Publisher's VersionAbstract
With the development of technology and the overwhelming expansion of the social networks in people’s daily life nowadays, a completely new branch in the direct marketing has emerged, and that is the influencer marketing. Influencer - marketing is emerging as a new and successful tool for promoting products, with more and more people appearing on social media. Over the years, the rate of influencers in digital marketing has been increasing, and it is believed that they can influence consumers’ decision to buy products directly. The emergence of influencers and their engagement is relatively new, hence the question of the status of influencers and their commercial activity in the legal system becomes an issue worth considering and regulating. How do influencers make money? Is there regulation for their actions? Are their actions in the internet space limited? What is their status? Do they pay taxes? These questions are the subject for analysis and elaboration in this text. The legal scope of this influencer – marketing is entering in many aspects of the Macedonian legal system, thus providing space for legal analysis, interpretation and regulation. This text in particular aims to make an analysis of the legal aspects of the contracts between the influencers and the brands, as well as the legal impact of the influencers’ actions on the consumers’ rights.
Bastard P, Vazquez S LLMTWCYGLVBZPRCJAT. Vaccine breakthrough hypoxemic COVID-19 pneumonia in patients with auto-Abs neutralizing type I IFNs. Science Immunology [Internet]. 2022. Publisher's VersionAbstract
ife-threatening ‘breakthrough’ cases of critical COVID-19 are attributed to poor or waning antibody response to the SARS-CoV-2 vaccine in individuals already at risk. Pre-existing autoantibodies (auto-Abs) neutralizing type I IFNs underlie at least 15% of critical COVID-19 pneumonia cases in unvaccinated individuals; however, their contribution to hypoxemic breakthrough cases in vaccinated people remains unknown. Here, we studied a cohort of 48 individuals (age 20-86 years) who received 2 doses of an mRNA vaccine and developed a breakthrough infection with hypoxemic COVID-19 pneumonia 2 weeks to 4 months later. Antibody levels to the vaccine, neutralization of the virus, and auto-Abs to type I IFNs were measured in the plasma. Forty-two individuals had no known deficiency of B cell immunity and a normal antibody response to the vaccine. Among them, ten (24%) had auto-Abs neutralizing type I IFNs (aged 43-86 years). Eight of these ten patients had auto-Abs neutralizing both IFN-α2 and IFN-ω, while two neutralized IFN-ω only. No patient neutralized IFN-β. Seven neutralized 10 ng/mL of type I IFNs, and three 100 pg/mL only. Seven patients neutralized SARS-CoV-2 D614G and the Delta variant (B.1.617.2) efficiently, while one patient neutralized Delta slightly less efficiently. Two of the three patients neutralizing only 100 pg/mL of type I IFNs neutralized both D61G and Delta less efficiently. Despite two mRNA vaccine inoculations and the presence of circulating antibodies capable of neutralizing SARS-CoV-2, auto-Abs neutralizing type I IFNs may underlie a significant proportion of hypoxemic COVID-19 pneumonia cases, highlighting the importance of this particularly vulnerable population.
Zdraveva A. Правна заштита на компјутерски програми. 9th International Scientific Conference " Social Changes in the Global World". 2022.Abstract
Идејата на овој труд е да се утврди на кој начин се обезбедува правната заштита на компјутерските програми. Законодавството на ЕУ го има во предвид зголеменото значење на овој тип на технологија, а се повеќе внимание се посветува на законската регулатива за заштита на компјутерските програми, со цел да се обезбеди соодветна безбедност и да се поттикнат поединците се повеќе да придонесуваат во оваа област. Различни правни системи се стремат да ја уредат оваа област преку збир на акти и прописи кои начелно се разликуваат во зависност од правната традиција во која припаѓаат. Засега не може да се каже дека европската, а уште помалку домашната судска пракса е богата со предмети поврзани со прекршување на авторските права на компјутерските програми. Но, неколку предмети, поради нивната специфичност, имаат особено влијание врз понатамошното постапување на судовите. Оттука, овој труд анализира како се применува релевантната законска регулатива низ праксата на Европскиот суд за човекови права во предметот SAS Institute Inc. vs. World Programming Ltd (WPL). Главните правни прашања кои се провлекуваат низ овој труд се, што е предмет на заштита кај компјутерските програми и кои елементи на компјутерската програма се штитат со авторските права.

Stojkovikj S, El-Nagar GA, Firschke F, Pérez LPC, Choubrac Léo, Najdoski M, Mayer MT. Electrocatalyst Derived from Waste Cu–Sn Bronze for COConversion into CO. ACS Applied Materials & Interfaces [Internet]. 2021;13(32):38161-38169. Publisher's VersionAbstract
To sustainably exist within planetary boundaries, we must greatly curtail our extraction of fuels and materials from the Earth. This requires new technologies based on reuse and repurposing of material already available. Electrochemical conversion of CO2 into valuable chemicals and fuels is a promising alternative to deriving them from fossil fuels. But most metals used for electrocatalysis are either endangered or at serious risk of limitation to their future supply. Here, we demonstrate a combined strategy for repurposing of a waste industrial Cu–Sn bronze as a catalyst material precursor and its application toward CO2 reuse. By a simple electrochemical transfer method, waste bronzes with composition Cu14Sn were anodically dissolved and cathodically redeposited under dynamic hydrogen bubble template conditions to yield mesoporous foams with Cu10Sn surface composition. The bimetal foam electrodes exhibited high CO2 electroreduction selectivity toward CO, achieving greater than 85% faradaic efficiency accompanied by a considerable suppression of the competing H2 evolution reaction. The Cu–Sn foam electrodes showed good durability over several hours of continuous electrolysis without any significant change in the composition, morphology, and selectivity for CO as a target product.
Boetcher T, Stojkovikj S, Khadke P, Kunz U, Mayer MT, Roth C, Ensinger W, Muench F. Electrodeposition of palladium-dotted nickel nanowire networks as a robust self-supported methanol electrooxidation catalyst. Journal of Materials Science [Internet]. 2021;56:12620–12633. Publisher's VersionAbstract
Mass activity and long-term stability are two major issues in current fuel cell catalyst designs. While supported catalysts normally suffer from poor long-term stability but show high mass activity, unsupported catalysts tend to perform better in the first point while showing deficits in the latter one. In this study, a facile synthesis route towards self-supported metallic electrocatalyst nanoarchitectures with both aspects in mind is outlined. This procedure consists of a palladium seeding step of ion track-etched polymer templates followed by a nickel electrodeposition and template dissolution. With this strategy, free-standing nickel nanowire networks which contain palladium nanoparticles only in their outer surface are obtained. These networks are tested in anodic half-cell measurements for demonstrating their capability of oxidising methanol in alkaline electrolytes. The results from the electrochemical experiments show that this new catalyst is more tolerant towards high methanol concentrations (up to 5molL&#x2212;1">) than a commercial carbon supported palladium nanoparticle catalyst and provides a much better long-term stability during potential cycling.

Introduction. COVID-19 pandemic threatens global human health. Reverse-transcription quantitative polymerase chain reaction (RT-qPCR) is a reference test for identification of acute SARS-CoV-2 infection, but it is associated with results delay. There is a need of fast and reliable tests which can improve the efforts of controlling the transmission of SARS-CoV-2. Aim. The aim of this study was to determine the analytical value of the rapid SARS-CoV-2 Ag-test in relation to the Ct values of the RT-qPCR. Methods. The study group comprised outpatients suspected for COVID-19, sampled twice, first for the routine RT-qPCR, and second for SARS-CoV-2 antigen testing. The results obtained by the rapid antigen test (Panbio™ COVID-19) were evaluated in relation to Ct values of the SARS-CoV-2 E-gene, obtained by RTqPCR Allplex 19-nCoV multiplex assay platform. Results. SARS-CoV-2 prevalence, based on RT-qPCR, was 50.8% (186/366). Specificity of the PanbioTM COVID- 19 Ag Rapid Test was 100%. Test sensitivity was 73.8%. Restricting RT-qPCR to Ct-values<30 increased test sensitivity to 91.2%. Conclusion. The findings underscored the epidemiological value of the rapid Ag-test since it reliably identifies contagious SARS-CoV-2 infected individuals who actively spread the virus in the community.

Introduction: When we start our work as medical professionals the most important was improving and understanding physical growth and nutrition. Today we know that as much important as good knowledge in physical examination is adequate assessment of personality and social development which is crucial for appropriate developmental assessment. In this context early identification of developmental delay is not just responsibility but either obligation of all health care professionals, especially pediatricians. Aim of the Study: The aim of this study is to analyze developmental monitoring based on parents informations in our hospital in order to find out which percentage of referred children has to be followed further and has to start with early intervention. Our approach to developmental monitoring is: we start the pediatric assessment by taking very careful history of child. Second step is very careful examination in order to find if the child has same kind of organ dysfunction. In second step crucial is neurological examination especially if we know that children with developmental disabilities have very high rate of seizure disorder, structural MRI abnormalities - especially frontal atrophy… Pediatrician has to be aware that observation of the parent-child interaction also, may be an aid in identifying children with delayed development. Methodology and Sample: The developmental monitoring in 465 children at the age of 12 - 60 months, referred as children with developmental delay according to primary care pediatricians, special educators or family members in the period of 4 years (from January 2016 until the end of 2019) was implemented. The assessment of the evaluated sample is done using CDC developmental milestone checklist (Centers for Disease Control and Prevention) for specific ages -12 and 18 months and 2,3,4 and 5 years. To assess behavioral and emotional problems, physicians need information from family and people who see children in their everyday contexts. Results: The results were presented for each group separately. Conclusion: Research indicates that the first five years of a child’s life are critical to brain development, academic achievement and later life outcomes. The right developmental and behavioral assessment can change the trajectory of a child’s life forever.

Во овој труд е презентиран нов, хемиски метод за визуелизација на латентни отпечатоци од прсти на површина од месинг од неиспукани куршуми. Методот е базиран на селективна хемиска депозиција на олово (II) сулфид во просторот помеѓу папиларните линии на површина. Постапката е едноставна и се состои од краткотрајно потопување на куршумите во раствор за визуелизација. Растворот за визуелизација на отпечатоците е приготвен со мешање на водни раствори од олово (II) ацетат, натриум хидроксид, триетанол амин и тиоуреа. Хемискиот процес се одвива во алкална средина и умерено загревање. Испитувањето на хемискиот состав на депонираниот материјал, беше извршено со прашкова рендгенска дифракција (XRPD). Дизајнирањето на овој метод беше спроведено со употреба на значителен број на примероци од неиспукани куршуми, при што беше испитувана и можноста за визуелизација на релативно стари отпечатоци. Притоа, успешно беа визуелизирани отпечатоци кои беа нанесени пред околу 2 години. Предложениот метод е релативно едноставен за изведување, што го прави потенцијално корисен при форензички испитувања. Клучни зборови: латентни отпечатоци, олово (II) сулфид, неиспукани куршуми, форензичка хемија, хемиска депозиција

Со развојот на технологијата и масовната експанзија на социјалните мрежи восекојдневниот живот на луѓето денес, дојде до појава на сосема нова гранка во директниотмаркетинг, а тоа е инфлуенсерството. Инфлуенсер – маркетингот се појавува како нова и успешнаалатка за промовирање на прозводи, при што сè повеќе луѓе се појавуваат на социјалните мрежи.Со текот на годините, стапката на инфлуенсери во дигиталниот маркетинг сè повеќе се зголемува,при што се верува дека тие можат да влијаат врз одлуката на потрошувачите директно да ги купатпроизводите. Појавата на инфлуенсерството и нивниот ангажман е релативно ново, па оттукапрашањето за статусот на инфлуенсерите и нивната комерцијална активност во правниот системстанува прашање вредно за разгледување и регулација. Како заработуваат инфлуенсерите? Постоили регулација за нивните дејствија? Ограничени ли се нивните дејствија во интернет просторот?Каков е нивниот статус? Дали плаќаат даноци? Овие прашања заземаат централно значење воелаборацијата на овој текст. Имено, правните аспекти на овој нов вид на маркетинг задираатво повеќе сфери од македонскиот правен систем, притоа оставајќи широк простор за анализа,интерпретација и регулација. Овој текст има за цел да направи анализа на правните аспекти оддоговорите за соработка и маркетинг, дејствијата на т.н. инфлуенсери низ призмата на правото инивниот однос со правата и слободите на потрошувачите.
