Some adverse outcomes include perinatal and neonatal infant mortality, major morbidity and mortality of children under two years, violation of psychomotor and physical development, cognitive disturbances and disability of children under age five. Finding ways to solve these issues remain a priority. The research involved two female groups. The experimental group included 403 women after the involuntary termination of pregnancy, premature birth or in case of threat of miscarriage; the control group included 402 women with physiological course of pregnancy and parturient with full-term pregnancy. The study required the application of systemic approaches and methods including structural, logical, medical and statistical analyses. The survey revealed more than 20 infectious risk factors and more than 70 factors of extragenital origin. The most significant infectious pathologies included COVID-19 (36.23 ± 2.29% and 14.93 ± 1.78%), herpes type 1 (5.96 ± 1.18% and 1.0 ± 0.50%), toxoplasmosis (4.22 ± 1.0% and 1.0 ± 0.50%) and chlamydial infection (4.22 ± 1.0% 0.50 ± 0.35%) in the experimental and control groups, respectively (P < 0.01). The most significant extragenital pathologies involved autoimmune thyroiditis (8.68 ± 1.40% and 0.75 ± 0.43%), type 1 diabetes mellitus (2.23 ± 0.74% and 0%) and allergic rhinitis/sinusitis (3.97 ± 0.97% and 0.50 ± 0.35%) in the experimental and control groups, respectively (P < 0.01).

However, almost half of the smallest infants still require intubation and mechanical ventilation in the first 72 hours after birth. It is known that ineffective initial CPAP is associated with a poorer prognosis. Therefore, the search for reliable prognostic risk factors for ineffective CPAP in very preterm neonates whose respiratory support is started with CPAP is still relevant today. The results of a retrospective cohort study conducted at the Lviv Regional Clinical Hospital (Ukraine), which included 151 children with birth weight <1500 g and gestational age <32 weeks, showed that CPAP failure occurred at a median age of five hours in 31% of infants initially treated with CPAP and average (SD) FiO2, while the failure point was 0.48 (0.15). The prevalence of the main risk factors for severe nRDS did not differ significantly between two groups (CPAP success and CPAP failure). The risk of CPAP failure was significantly associated with surfactant treatment (OR – 7.46; 95% CI: 2.3–24.2), severe RDS (OR – 12.17; 95% CI: 3.8–39.3), requirement in resuscitation after birth (OR – 3.10; 95% CI: 1.2–8.1), initial CPAP pressure (OR – 0.38; 95% CI: 0.15–0.99). Earlier administration of exogenous surfactant to children at high risk of developing severe RDS could prevent the need for mechanical ventilation.

Therefore, the study aimed to reveal the interrelationship between thyroid dysfunction and COVID-19 severity­ as well as to determine optimal cut-off values for screening for thyroid disorders in children. A total number of 90 children aged from 1 month to 17 years were involved in the study. Patients with known thyroid disease were not recruited for the research. A thyroid panel was assessed for all participants that included: free triiodothyronine (FT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH) and anti-thyroid peroxidase (ATPO) antibodies. Statistical analysis was done using the computer software Statistica 13.0. Research has revealed euthyroid sick syndrome (ESS) in 14.10% of SARS-CoV-2 infected children more often among patients with severe COVID-19 and multisystem inflammatory syndrome (33.33%) compared to mild COVID-19 course (6.67%) and moderate disease severity (8.89%) (P < 0.05). Significant correlation relationships were revealed for next values – FT3 and erythrocyte sedimentation rate (ESR) (rs = -0.22; P < 0.05); FT3 and C-reactive protein (CRP) (rs = -0.33; P < 0.05); FT3 and procalcitonin (rs = -0.43; P < 0.05). The next cut-off values for ESS determination were revealed: ESR 18.5 mm/h (AUC 0.803); CRP 11.5 mg/l (AUC 0.763); ferritin 84.8 ng/ml (AUC 0.733).

We observed that the addition of electron withdrawing group (–Cl) to cyclic RGD-containing peptides-based compound induced a radical improvement in the hydrogen bond strength with Arg139 in Bcl-XL. Compound F with -9.2 kcal/mol was observed to be positioned at the best-docked site in the binding pocket of Bcl-XL and therefore suggested to have greater potential anticancer abili­ty than other studied compounds as well as the referenced compound (Doxorubicin).

Creatine phosphokinase (CPK), lactate dehydrogenase (LDH), catalase, superoxide dismutase, glutathione peroxidase (GPx) activity and the level of creatinine, lactate, hydrogen peroxide, reduced glutathione were estimated with clinical diagnostic kits.

Osteoporosis in rats was induced by long-term (30 days) administration of the synthetic glucocorticoid prednisolone (5 mg/kg of b.w.). Calcium and inorganic phosphate levels, activity of alkaline phosphatase (ALP) in serum, bone tissue and bone marrow were determined spectrophotometrically. The protein levels of VD3 receptor (VDR), receptor activator of nuclear factor kappa-B (RANK), its ligand (RANKL), and osteoprotegerin (OPG) in bone tissue were determined by Western blotting. Serum 25-hydroxyvitamin D3 (25OHD3) content was assayed by ELISA. It was shown that prednisolone caused the development of hypocalcemia and hypophosphatemia, increased the alkaline phosphatase activity in the blood serum, while downregulating its activity in bone tissue and bone marrow. GC-induced osteoporosis was accompanied by a profound deficiency of VD3 and a decrease in the content of VDR. Evaluation of the NF-κB-associated cytokine axis RANK/RANKL/OPG, which regulates the balance of osteoblasts/osteoclasts, showed a simultaneous decrease in the RANK content and OPG/RANKL ratio. Vitamin D3 restored mineral metabolism and 25OHD3 level that led to the normalization of VDR-mediated signaling­ and RANK/RANKL/OPG functions in bone tissue. It has been shown that the administration of MBPA had a corrective effect on the content of mineral components in the blood serum and bone tissue, as well as on the activity­ of alkaline phosphatase only in combination with vitamin D3, indicating a low efficiency of bisphosphonate monotherapy in GC-induced vitamin D3 deficiency and osteoporosis.

In the present paper, we show that choline and its derivatives (phosphocholine (PC), L-α-glycerophosphocholine (G-PC) and 1-palmitoyl-sn-glycero-3-phosphocholine (P-GPC)) dose-dependently influence cytochrome c release from isolated mouse liver mitochondria. Choline inhibited Ca2+-stimulated cytochrome c release, while PC attenuated wortmannin-induced cytochrome c release. Small doses of G-PC and P-GPC (up to 0.1 µM) were protective against either Ca2+ or wortmannin, while larger doses (up to 1 µM) stimulated cytochrome c release by themselves. Choline and PC disrupted interaction of VDAC1, Bax and Bcl-2 with mitochondrial α7 nAChRs and favored their interaction with α9 nAChR subunits.
