Objective: To compare the long-term results of LSG and RYGB with a fixed restrictive component in patients with morbid obesity in terms of weight loss, control of associated diseases and the development of long-term complications, including sarcopenia.Materials and methods: our study included the results of treatment of 251 patients (153 LSG and 98 RYGB). The follow-up period was at least 24 months (median follow-up 38 months). The restrictive component was assessed 12 months after surgery using CT-volumetry. The size of the gastroenetroanastomosis was additionally measured using fibrogastroscopy in the RYGB group. The bioelectrical impedance analysis (BIA) was used to assess body composition and determine the skeletal muscle mass index (SMMI) initially and during control examinations in the postoperative period.Results: both groups obtained good results in terms of weight loss and control of associated diseases, however, RYGB shows some advantages in these parameters. On the other hand, in the RYGB group a higher rate of progression of signs of sarcopenia was detected (8.2% (including 3% of severe sarcopenia) vs 3.3% in the LSG group). Most patients who progressed to sarcopenia were older, had type 2 diabetes mellitus (T2DM), or had mild sarcopenia at baseline.Conclusions: RYGB demonstrates better results in terms of weight loss and control of associated diseases compared to LSG, however, in elderly patients, as well as in the presence of T2DM or signs of sarcopenia, it is advisable to choose operations without a pronounced malabsorptive effect.

Objective: to evaluate the role of blood-sucking mosquitoes of various species living in the northern and central regions of the Crimean Peninsula in the transmission of West Nile virus (WNV).Materials and methods: the collection of bloodsucking mosquitoes was carried out in 7 administrative units of the Republic of Crimea with automatic traps and a vertical handheld vacuum cleaner from July 1 to August 5, 2022. The species composition of mosquitoes was determined visually using an MSP-1 stereomicroscope (option 22) using standard keys. Detection of WNV RNA in the samples was performed by RT-PCR. Mosquito infection levels and dominance index were calculated.Results: a common eudominant species for urban and rural biotopes of the surveyed areas was determined Ae. caspius, whose dominance index was 72.4% and 31.3%. Mosquitoes of the species Cx. modestus were the most numerous in rural biotopes (dominance index — 48.4%). The invasive species Ae. albopictus in the central part of the Crimean peninsula, which indicates the expansion of its habitat. Of 18.6 thousand mosquitoes of 12 species, merged in 693 samples, WNV RNA was detected in 14 samples (2.02%), 3 isolates of the pathogen were isolated. A high level of WNV infection of mosquitoes in urban biotopes was established, which amounted to 4.12%. WNV circulation was first confirmed in the northern part of Crimea (Krasnoperekopsky district).Conclusion: the epidemiological significance of mosquitoes of various species on the territory of the Crimean Peninsula has been determined. The data on the spread of WNV in the Republic of Crimea were supplemented, taking into account which the estimated zoning of the territory was carried out according to the degree of risk of infection with WNV. Recommendations are given to strengthen epidemiological surveillance and preventive measures.

Objective: to increase the effectiveness of in vitro fertilization in patients of late reproductive age by optimizing prepregnancy preparation for the IVF program.Materials and methods: The study included 67 patients of late reproductive age with a history of unsuccessful IVF attempts, divided into two groups at the second stage of the study, depending on the volume of prepregnancy preparation: group 1 (33 patients), group 2 (34 patients). The control group (50 patients) were healthy women of reproductive age. Immunohistochemical examination of the endometrium and microbiological examination of the uterine cavity, hormonal status of peripheral blood, study of the concentration of melatonin in peripheral blood and follicular fluid, antioxidant status of follicular fluid, expression of leukemia inhibitory factor (LIF) in the cervical secretion were performed.Results: in patients with age-related dysregulation of the hypothalamic-pituitary-ovarian axis and impaired fertile function, a systemic and local (in follicles) decrease in melatonin levels was revealed. The studied effects of melatonin suggested that its use in patients of late reproductive age with reduced follicular reserve and a "poor" response to ovarian stimulation may increase the effectiveness of in vitro fertilization (IVF).Conclusions: The inclusion in the pre-gravidar preparation of a complex of water-soluble polypeptide fractions of the epiphysis, stimulating the production of endogenous melatonin, made it possible to increase the effectiveness of IVF in patients by an average of 3.1 times according to the criterion of "clinical pregnancy" and 4.1 times according to the criterion of "live birth".

Modification of a natural zeolite from Klaten, Indonesia, as a catalyst in the dehydration of ethanol to produce diethyl ether (DEE) has been conducted. Raw Klaten natural zeolite (ZA) was modified using 1 and 2 M of an ammonium chloride solution for 24 h while stirring for 18 h, then calcined at 500 °C for 5 h under N2 gas flow produced HZA1 and HZA2 catalyst, respectively. The catalysts were characterized using XRD, BET surface area, SEM-EDX, XRF, FTIR and gravimetric acidity test using ammonia-based vapor. The dehydration process was conducted under variations of temperature (200, 250, and 300 °C) and catalyst mass of 0.1, 0.2, and 0.4 g for 20 mL of 96% ethanol. The HZA1 catalyst produced the highest yield of DEE (2.41%) at 250 °C and 0.1 g catalyst. This catalyst showed needle-like of 66.22 nm crystal size, consisting of 32.57% mordenite, the highest surface area (48.32 m2/g), crystallinity (32.93%) and Brønsted acid sites (2.75 mmol/g), the lowest pore diameter (1.77 nm) and Si/Al mol ratio (4.03). The HZA1 catalyst can be used repetitively and produced DEE yield at the second and third runs (2.40 and 2.61%).

This article presents studies on the modification of petroleum bitumen with polymer waste in the presence of vermiculite. An increase in temperature leads to an increase in the interaction of components, partial breakage of polyethylene and bitumen macromolecules, and the formation of radical-free valences. As a result, fragments of polyethylene and bitumen molecules react with each other, and the formation of qualitatively new structural formations occurs via the strong connection of polar and amorphous bitumen with nonpolar structurally viscous polyethylene. Domestically produced Kulantau vermiculite was used to ensure stable adhesion over a wide temperature range and increase the specific surface area, which acquired additional energy, resulting in an increase in the degree of adhesion to bitumen and increased durability of the binder with improved rheological characteristics. Because of the increased service life of road asphalt pavements, the use of the latter results in a considerable decrease in the cost of polymer-bitumen binders. Based on improved binder formulations, asphalt concrete exhibits excellent water resistance and strength at 50 °C (4.7 to 5.0 MPa). In summary, the modification of bitumen with polymer waste and vermiculite offers a promising avenue for improving the performance and longevity of asphalt pavements.

The safety and regulatory compliance of a widely used medical device have become a growing concern among a significant population. This has raised questions about the assessment of risks, monitoring of adverse drug reactions (ADR), and overall product safety. The efficacy and safety of such medical devices heavily rely on the regulations and guidelines set forth by regulatory agencies (RAs).
In the pharmaceutical industry, regulatory affairs (RA) professionals play a crucial role in overseeing the lifecycle of healthcare products. They provide strategic, tactical, and operational guidance to ensure compliance with regulations, facilitating the efficient development and delivery of safe and effective healthcare products worldwide. Evaluating adherence to regulations requires a combination of expertise from the business, legal, and pharmaceutical domains.
Regulatory authorities must thoroughly monitor medical device design, development, and manufacturing processes to guarantee that the products reaching the market are safe and effective. The certification process is intricate, involving multiple steps and the assessment of materials by competent authorities. In the United States, manufacturers must seek marketing authorization from the United States Food and Drug Administration (USFDA) through two primary application types: 510(k) and Pre-Market Application (PMA). In the European Union (EU), national authorities grant permission for the sale of medical devices, employing a third-party compliance system where notified bodies ensure quality assurance pre- and post-approval. In India, the Central Drug Standard Control Organization (CDSCO) licenses devices for sale and import under the CLAA framework.
Conclusion
Pharmaceutical regulatory affairs experts play a critical role in ensuring compliance with industry requirements for all pharmaceutical products. This review provides an overview of how medical devices are regulated and monitored in the EU, India, and the USA, emphasizing the importance of regulatory affairs in maintaining the safety and efficacy of healthcare products.

The market for biotechnology-derived medicinal products is evolving rapidly with the imminent entry of biosimilars. The development and approval of biosimilars represent a critical pathway to expanding access to biological therapies while maintaining high standards of safety, efficacy and immunogenicity profile because biosimilars are made in living organisms there may be some minor differences from the reference medicines.
In the US, biosimilars are regulated under the Biologics Price Competition and Innovation Act (BPCIA), which is part of the Affordable Care Act. The regulatory pathway emphasizes a stepwise approach, involving analytical studies, preclinical assessments, and comparative clinical trials to establish biosimilarity with a reference product. The FDA assesses the totality of evidence provided by the biosimilar applicant to make a determination on safety, purity, and potency.
In the EU, the approval process for biosimilars is governed by the European Medicines Agency (EMA). The regulatory framework relies on a robust comparability exercise, emphasizing extensive analytical studies and well-designed clinical trials to establish biosimilarity. The EMA assesses the comprehensive data package submitted by the biosimilar applicant, considering the totality of evidence before granting marketing authorization.
While the overall approach is similar, there are nuanced differences in the regulatory processes. The US typically requires a more prescriptive approach to clinical trials, with the expectation of conducting at least one confirmatory comparative clinical trial. In contrast, the EU may allow for a more tailored approach to clinical development, recognizing that the need for extensive clinical trials may vary depending on the nature of the biosimilar and the reference product.
As the biosimilar landscape continues to evolve, ongoing collaboration and harmonization efforts between regulatory authorities aim to streamline global access to high-quality ,cost-effective biologic therapies.

Introducción: el síndrome de Percheron es una entidad infrecuente de difícil determinación clínica y que es causada por la oclusión de la arteria de Percheron.
Presentación del caso: paciente masculino de 71 años que llega obnubilado al servicio de urgencias, con disartria, hemiparesia izquierda, signo de Babinski bilateral, ptosis palpebral derecha, con exotropía, limitación total de la aducción del ojo derecho y abducción parcial del izquierdo, con imposibilidad de supraducción e infraducción de ambos ojos. Además, tenía reflejo oculocefálico vertical ausente bilateralmente y horizontal derecho ausente, pupilas anisocóricas y reflejo fotomotor ausente en ambos ojos. La imágenes obtenidas por resonancia magnética nuclear (RMN) (T1W, T2, T2-FLAIR y técnicas de difusión) demostraron que hubo un infarto de la arteria de Percheron. El paciente se mantuvo por 10 días hospitalizado y evolucionó favorablemente.
Discusión: el síndrome de Percheron cursa con una triada clásica caracterizada por alteración de la conciencia, deterioro cognitivo y parálisis de la mirada vertical, a lo que se le añade hemiplejía, ataxia cerebelosa y déficit oculomotor y, si se acompaña de lesiones mesencefálicas, se produce un síndrome tálamo-peduncular. La sospecha clínica de esta patología constituye un desafío en la práctica médica, debido a la infrecuencia de presentación, variabilidad de alteraciones neurológicas y la dificultad que ofrecen los estudios imagenológicos de urgencia.
Conclusiones: hemos descrito una entidad infrecuente y de difícil determinación clínica, en la cual, los criterios para el diagnóstico son fundamentalmente imagenológicos, siendo de elección la RMN. La evolución y el pronóstico dependerán de la extensión del proceso, las estructuras involucradas, el diagnóstico y su tratamiento oportuno.
