Objective: The aim: To establish the effectiveness of thromboelastography (TEG) and tranexamic acid (TXA) for prognosis and prevention of early postpartum period bleedings (PPB) for postpartum women with idiopathic arterial hypotension (IAH).

Patients and methods: Materials and methods: Coagulogical research was conducted (coaugologram screening, dynamic function of platelets under the influence of adenosine diphosphate (ADP) (visual assessment), measurement of soluble fibrin-monomer complexes (FMC) and TEG of 36 in parturient women during the I chilbirth period with arterial hypotension. 14 parturient women with normal fibrinolysis were included into the first observation group; The second group includes 22 parturient women with TEG results which show signs of hyperfibrinolysis. Further, in cases when stronger fibrinolysis was detected during the late pushing phase of childbirth period, the TXA by amount of 1,0 g IV (bolus) was injected due to bleeding prevention. TEG was repeated during early postpartum period.

Results: Results: the inhibition of platelet aggregation activity with ADP was observed in every parturient woman with IAH in the first partum period. In 61,1% cases with TEG hyperfibrinolysis were shown, which was accompanied by significant increase in FMC levels in blood. The use of TXA as PPB prevention for parturient women with IAH and hyperfibrinolysis during TEG was fully oppressing the fibrinolytic activity and was not affecting the coagulation part of hemostasis.

Conclusion: Conclusions: hemostasis testing during childbirth based on TEG gives the ability to prognose the hemorrhagic complications in parturient women with IAH and administer their prophylaxy using TXA.

A series of 11-substituted 3,5,10,11-tetrahydro-2H-benzo[6,7]thiochromeno[2,3-d][1,3]thiazole-2,5,10-triones were obtained via hetero-Diels-Alder reaction of 5-alkyl/arylallylidene/-4-thioxo-2-thiazolidinones and 1,4-naphthoquinones. The structures of newly synthesized compounds were established by spectral data and a single-crystal X-ray diffraction analysis. According to U.S. NCI protocols, compounds 3.5 and 3.6 were screened for their anticancer activity; 11-Phenethyl-3,11-dihydro-2H-benzo[6,7]thiochromeno[2,3-d]thiazole-2,5,10-trione (3.6) showed pronounced cytotoxic effect on leukemia (Jurkat, THP-1), epidermoid (KB3-1, KBC-1), and colon (HCT116wt, HCT116 p53-/-) cell lines. The cytotoxic action of 3.6 on p53-deficient colon carcinoma cells was two times weaker than on HCT116wt, and it may be an interesting feature of the mechanism action.
C60 fullerene (C60) as a nanocarbon particle, compatible with biological structures, capable of penetrating through cell membranes and effectively scavenging free radicals, is widely used in biomedicine. A protective effect of C60 on the biomechanics of fast (m. gastrocnemius) and slow (m. soleus) muscle contraction in rats and the pro- and antioxidant balance of muscle tissue during the development of muscle fatigue was studied compared to the same effect of the known antioxidant N-acetylcysteine (NAC). C60 and NAC were administered intraperitoneally at doses of 1 and 150 mg kg−1, respectively, daily for 5 days and 1 h before the start of the experiment. The following quantitative markers of muscle fatigue were used: the force of muscle contraction, the level of accumulation of secondary products of lipid peroxidation (TBARS) and the oxygen metabolite H2O2, the activity of first-line antioxidant defense enzymes (superoxide dismutase (SOD) and catalase (CAT)), and the condition of the glutathione system (reduced glutathione (GSH) content and the activity of the glutathione peroxidase (GPx) enzyme). The analysis of the muscle contraction force dynamics in rats against the background of induced muscle fatigue showed, that the effect of C60, 1 h after drug administration, was (15–17)% more effective on fast muscles than on slow muscles. A further slight increase in the effect of C60 was revealed after 2 h of drug injection, (7–9)% in the case of m. gastrocnemius and (5–6)% in the case of m. soleus. An increase in the effect of using C60 occurred within 4 days (the difference between 4 and 5 days did not exceed (3–5)%) and exceeded the effect of NAC by (32–34)%. The analysis of biochemical parameters in rat muscle tissues showed that long-term application of C60 contributed to their decrease by (10–30)% and (5–20)% in fast and slow muscles, respectively, on the 5th day of the experiment. At the same time, the protective effect of C60 was higher compared to NAC by (28–44)%. The obtained results indicate the prospect of using C60 as a potential protective nano agent to improve the efficiency of skeletal muscle function by modifying the reactive oxygen species-dependent mechanisms that play an important role in the processes of muscle fatigue development.

Abstract
Introduction: The main task of palliative care is to improve the quality of life of a patient, and the therapy of chronic pain with opioids is a significant problem for palliative care patients in Ukraine. Therefore, this study aimed to assess the opioid availability for palliative care patients in Ukraine.
Methods: Analysis of the list and consumption of opioids according to the scientific publications and legal documents.
Results: It was found that in Ukraine as of June 2021, 12 international non-proprietary names of opioids were registered, most of which are represented by several dosage forms, which makes it possible for patients to receive adequate pain relief through non–invasive therapy with oral forms. It was shown that two thirds (63.2%) of trade names of opioids registered in Ukraine were of domestic origin. Based on a comparative analysis of the range of opioids, available in current regulatory documents, it was established that in the State Register of Medicines of Ukraine and the Unified clinical protocol there is an almost identical list of opioids (12 drugs). However, in the State Drug Formulary and the National List of Essential Medicines, this list is much smaller (8 and 5 drugs, respectively). Since 2013 changes in the regulatory documents on the medical use of opioids in Ukraine have occurred, and oral morphine was registered for the first time, allowing access to adequate pain relief. Analysis of the morphine consumption level by dosage forms has shown that before 2013, the pharmacies sold only morphine in injections, and since 2013, the consumption of oral morphine increased.
Conclusions. Changes in regulatory documents partially simplified the complicated process of obtaining opioids by patients. However, more than 80% of patients still do not receive adequate pain therapy due to the hesitancy of doctors to prescribe opioids and an extremely insufficient number of pharmacies (1.8%) that sell opioids for the population.

Introduction

Many clinical studies have proved the effectiveness of probiotics in metabolic disorders associated with insulin resistance. However, the impact of probiotic therapy on pancreatic β-cell function is ambiguous. The influence of probiotic supplementation vs. placebo on β-cell function in people with type 2 diabetes (T2D) was assessed in a double-blind, single-center, randomized, placebo-controlled trial (RCT).

Methods

Sixty-eight patients with T2D were selected for participation in the RCT. Patients were randomly allocated to consumption of live multistrain probiotics or a placebo for 8 weeks, administered as a sachet formulation in double-blind treatment. The primary main outcome was the assessment of β-cell function as change in C-peptide and HOMA-β (homeostasis model assessment-estimated β-cell function), which was calculated using the HOMA2 calculator (Diabetes Trials Unit, University of Oxford). Secondary outcomes were the changes in glycemic control-related parameters, anthropomorphic variables, and cytokines levels. Analysis of covariance was used to assess the difference between groups.

Results

Supplementation with live multiprobiotic was associated with slight significant improvement of β-cell function (HOMA-β increased from 32.48 ± 13.12 to 45.71 ± 25.18; p = 0.003) and reduction of fasting glucose level (13.03 ± 3.46 vs 10.66 ± 2.63 mmol/L and 234.63 ± 62.36 vs 192.07 ± 47.46 mg/dL; p < 0.001) and HbA1c (8.86 ± 1.28 vs 8.48 ± 1.22; p = 0.043) as compared to placebo. Probiotic therapy significantly affects chronic systemic inflammation in people with T2D by reducing pro-inflammatory cytokine levels.

Conclusions

Probiotic therapies modestly improved β-cell function in patients with T2D. Modulating the gut microbiota represents a new diabetes treatment and should be tested in more extensive studies.
