Over the last decade, there has been an increase in illegal drug use and uncontrolled opioid abuse in patients with chronic pain, which is associated with unintentional trauma and is a major risk factor for tolerance and withdrawal, leading to overdose and death [1-5]. The attention of scientists in various fields of medicine is focused on the study of changes in organs and systems under the influence of drugs, in particular, both in clinical and experimental
areas [6-9]. In clinical studies it is indicated that when exposed to opioids there are signs of immunosuppression, which cause an increased risk of infectious diseases and the development of inflammation [5, 10, 11]. Toxic effects of drugs are manifested in all organs and systems, which
may have an indirect or direct effect on the organs of the oral cavity [6, 12-15]. The question of the role of bacterial flora in the etiology and initiation of periodontal disease is certainly actively studied as the improvement of microbiological methods and the accumulation of research results [16-19]. Today,
one of the main hypotheses remains that dental plaque microorganisms are a determining factor in the development and progression of the inflammatory process in the periodontium, which provoke the inflammatory process and directly affect the microbial status of the oral cavity [20- 23].There is also evidence that the role of microorganisms in the development of periodontitis is unclear, although some bacterial pathogens alone or as part of microbial groups may be particularly important [24]. Therefore, in order to prevent the development of periodontal disease and the occurrence of infectious foci in the oral cavity caused by bacterial biopellicle, it is important to determine the etiology and pathogenesis of this pathology in experimental animal models in order to further extrapolate these data to the clinic [25]. However, the relationship between the species and quantitative composition of the microbiota of tooth surface in the gingival margin and the development and progression of inflammation in the gingival mucosa under action of the opioid are controversial and needs further study using modern methods of microbiological research in the experiment.

З початком агресивної російсько-української війни в Україні зросли негативні чинники, що призводять до загострення паразитарної ситуації. Антропогенний вплив багатофакторний і пов’язаний з масивним забрудненням навколишнього середовища, зміною клімату, соціально-економічними процесами – урбанізацією, міграцією населення, погіршенням санітарних умов проживання людей, утримання тварин.
Мета: проаналізувати характер і структуру паразитарних інвазій за 2022, 2023 роки у Львівській області за даними результатів лабораторних досліджень приватного підприємства «МОТАЛАБ».

Polycystic ovary syndrome (PCOS), an endocrine and metabolic disorder in women of reproductive age, is characterized by high androgen levels, irregular periods, and small cysts in the ovaries. PCOS affects approximately 10 % of reproductive age women of all races and ethnicities. PCOS has been recognized to affect women of reproductive age since antiquity and in the 21st century, it emerges as the most widespread and serious reproductive metabolic disorder in the world. PCOS is a multifactorial disorder that affects both the reproductive and metabolic health of women. In addition, PCOS is a leading symptom of infertility in women. Nevertheless, women with PCOS who become pregnant unfortunately have an increased risk of complications, such as gestational diabetes mellitus (GDM), preterm birth. Many people believe GDM disappears after childbirth, despite the fact that GDM is a warning symptom of type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. According to growing evidence, GDM complicates 40 % of PCOS pregnancies, suggesting that PCOS is a risk factor for GDM. Hence, PCOS is a lifelong disorder that can eventually lead to various long-term health complications, including chronic menstrual irregularity, infertility, endometrial hyperplasia, and endometrial cancer. Thus, it’s a scientific fact that both PCOS and GDM are significantly associated with each other. However, most studies on the risk of GDM in PCOS patients are retrospective. Therefore, there is no strong evidence whether PCOS is a risk factor for GDM or any other related factor. PCOS, a polygenic endocrinopathy, is in a true sense a set of diseases that worsen the state of the body. Reproductive and metabolic disorders associated with PCOS cause several clinical symptoms, such as irregular and painful periods, hirsutism, acanthosis nigricans, acne, psoriasis, anxiety, mood swings, patterned baldness, cardiovascular problems, type 2 diabetes, infertility, pelvic pain, low libido, low self-esteem, etc. Further studies are needed to understand the genetic and epigenetic contributions of PCOS, PCOS-related comorbidities, the role of placenta in nutrient availability, and influence of medications that may affect the long-term offspring health.

Opioid addiction has acquired the characteristics of an epidemic in recent years and is a serious problem in modern medicine. In users of narcotic substances, a significant prevalence of diseases of the oral cavity and periodontal tissues is noted in comparison with the general population. The aim of the work was to investigate the ultrastructural organization of the periodontal tissues of rats at the end of the fourteenth week of the experimental opioid effect. The animals were administered intramuscularly, daily, once, the opioid analgesic nalbuphine (pharmacotherapeutic group: analgesics, opioids, morphinan derivatives) in increasing doses for 14 weeks: 1-2 weeks - 0.212 mg/kg, 3-4 weeks - 0.225 mg/kg, 5-6 weeks - 0.252 mg/kg, 7-8 weeks - 0.260 mg/kg, 9-10 weeks - 0.283 mg/kg; 11-12 - 0.300 mg/kg, 13-14 weeks - 0.450 mg/kg. At the end of the fourteenth week of opioid exposure, ultrastructural changes in the epithelium of the mucous membrane of the gums, periodontium, and hemomicrovessels with the development of decompensation and pronounced dystrophic-destructive changes were established. With the long-term effect of an opioid analgesic, signs of karyorrhexis, segregation of nucleoli, spongiosis, apoptosis, violation of the integrity of intercellular contacts, as well as vacuole-like formations, which were a manifestation of focal necrosis of epitheliocytes, were revealed. The development of necrotic changes was caused by significant damage and destruction of organelles, as well as fragmentation or lysis of bundles of tonofilaments. The intercellular spaces were mostly expanded and uneven, which was caused by edematous phenomena. Fragmentation and destruction of periodontal collagen fibers, destructive changes in fibrocytes and fibroblasts were found in the periodontium. The translucency of the amorphous component of the intercellular substance of the connective tissue was determined. The ultrastructural reorganization of the cellular components of the periodontium was caused by vascular disorders of a systemic nature, which were manifested by the phenomena of dilatation, hemoptysis, sludge phenomenon, dystrophic changes in the endotheliocytes of hemocapillaries and venules, and the progression of sclerotic changes, which significantly disturbed the trophism of the periodontal tissues of rats.

Відповідними викликам, поставленим сьогоденням нашій країні, стали теми сьомого міжнародного симпозіуму «SMART LION», що відбувся 26 вересня 2023 року у межах відзначення 150-річного ювілею Наукового товариства імені Шевченка та 125-річчя з дня створення при ньому Лікарської комісії. Організаторам «SMART LION 2023» – професорам Валентині Чопяк, Оксані Заячківській та Василю Лончині вдалося зібрати цього року майже дві сотні учасників наживо і понад тисячу слухачів у режимі онлайн. Доповіді про розвиток реабілітації в Україні та її основні напрями представили Олена Лазарєва, Віра Рокошевська, Олег Білянський, Оксана Гдиря, Олег Фітькало. Критичною проблемою для сучасної України, що давно стала викликом світовій медицині, є розвиток посттравматичного стресового розладу (ПТСР). Саме тому Олег Березюк, керівник служби ментального здоров’я Національного реабілітаційного центру UNBROKEN, у доповіді підняв питання складності правильної діагностики та лікування ПТСР в умовах багатопрофільної лікарні, а професор Валентина Чопяк і д-р мед. наук Світлана Зубченко акцентували увагу присутніх на імунореабілітації ПТСР.

The seventh international symposium, SMART LION, was held on September 26, 2023. It was to celebrate the 150th anniversary of the Shevchenko Scientific Society and the 125th anniversary of the Medical Commission. The topics concerned the challenges our country faces today. Organizers of SMART LION 2023 are Professors Valentyna Chopyak, Oksana Zayachkivska, and Vassyl Lonchyna. They managed to gather almost two hundred participants offline and over a thousand guests online. Olena Lazareva, Vira Rokoshevska, Oleh Bilianskyi, Oksana Hdyria, and Oleh Fitkalo delivered their reports on the development of rehabilitation in Ukraine and its main avenues. The emergence of post-traumatic stress disorder (PTSD) is a critical challenge for contemporary Ukraine and has long been a significant obstacle for global medicine. That is the reason why Oleh Berezyuk, Head of the Mental Health Service of the UNBROKEN National Rehabilitation Center, brought up the matter of difficulties in correctly diagnosing and treating PTSD in the context of a multidisciplinary hospital, while Professor Valentyna Chopyak and MD Svitlana Zubchenko focused the attention of attendees on PTSD immune-rehabilitation.
