Functional outcomes and synovial fluid (SF) cytokine concentrations in response to platelet-rich plasma (PRP) or stromal vascular fraction (SVF) post-treatments following open wedge high tibial osteotomy (HTO) in 20 patients with knee osteoarthritis (OA) were examined. Six weeks after surgery, the knees of 10 patients were injected with autologous PRP (PRP subgroup), while another 10 patients were injected with autologous SVF (SVF subgroup) and monitored for 1.5 years. Pain assessment (VAS score) and functional activity (KOOS, KSS, Outerbridge, and Koshino scores) were applied. PRP subgroup performed better compared with the SVF subgroup according to KOOS, KSS, and VAS scores, while the SVF subgroup demonstrated better results according to Outerbridge and Koshino testing and produced more pronounced cartilage regeneration in the medial condyle and slowed down cartilage destruction in its lateral counterpart. SF was collected before and one week after PRP or SVF injections and tested for concentrations of 41 cytokines (Multiplex Assay). In the PRP subgroup, a significant decrease in IL-6 and CXCL10 synovial concentrations was accompanied by an increase in IL-15, sCD40L, and PDGF-AB/BB amounts. The SVF subgroup demonstrated a significant decrease in synovial TNFα, FLT-3L, MIP-1β, RANTES, and VEGF concentrations while SF concentrations of MCP-1 and FGF2 increased. Both post-treatments have a potential for increased tissue regeneration, presumably due to the downregulation of inflammation and augmentation of synovial growth factor concentrations.

BackgroundAlthough international publications on radiosurgery have increased exponentially, reports of heterogeneous series treated with linear accelerator (LINAC) are scarce. Since most intracranial tumors are irregular in size and not spherical, LINACs (Elekta Precise®, Elekta AB, Sweden), fitted with a multi-leaf collimator, allow for precise stereotactic radiosurgery for the entire tumor. AimTo evaluate the effects of LINAC on an outpatient basis with patients diagnosed with various intracranial malignancies. MethodologyA retrospective observational study of a series of cases of patients with intracranial lesions treated at the Institute of Oncology and Radiobiology using LINAC was carried out from October 2019 to May 2021 to evaluate the therapeutic results of radiosurgery in patients with intracranial tumors. ResultsA total of 22 lesions in 20 patients were treated with LINAC. The average age of the patients was 49.7, and the male-female ratio was 1:2. The cases consisted were mostly vestibular schwannoma (7 lesions), metastases from breast cancer (3 lesions), and tuberculum sellae meningioma (2 lesions). The prescription dose covered 99% of the planning target volume in 16 lesions (72.7%) and 100% in six lesions (27.3%) (prescription volume). In meningiomas and schwannomas, doses between 12 and 14 Gy were used, in plasmacytoma 13 Gy, in pilocytic astrocytoma 14 Gy, in cavernoma 15 Gy, in breast cancer metastasis between 18 and 20 Gy, and in lung cancer metastasis 22 Gy. When evaluating local control, 11 patients exhibited stable findings at the six-month control while 10 had partial regression, and a single patient had total regression. Minor complications such as perilesional edema, facial paresthesia, facial paralysis, and transient alopecia were observed in eight of the patients. ConclusionsPatients with extra-axial, low-grade malignancy, and posterior fossa lesions were predominant in the studied population. Radiosurgery treatment is associated with good local control of the treated lesions. Complications are infrequent, mild, and predominated by perilesional edema.

The article is dedicated to the assessment of the experience in drainage water purification from radionuclides using ion-selective purification method on Units 1,2 Novovoronezh-2 NPP. Application of an ion-selective sorbent based on nickel ferrocyanide, as well as the preliminary oxidation of corrosive origin radiongjuclides, allow to achieve a satisfactory quality of purification from Cs-134, Cs-137, Co-60, Co 58, Mn-54, Cr-51. However, this method turned out to be ineffective for drainage water purification from Be-7, Sb-124, Sb-125. The article presents a possible method for drainage water purification from Be-7, Sb-124, Sb-125 using an iron-based coagulant, prospects for the modernization of the ion-selective drainage water purification plant, as well as plans to improve methods for drainage water purification at Novovoronezh-2 NPP

BACKGROUND: Anesthetic management during interventions on the adrenal glands is quite complex. Difficulties in conducting anesthesia are often determined by concomitant obesity, which is associated with an increased sensitivity of the respiratory center to the action of opioids. This condition contributes to an increase in the frequency of respiratory and other disorders with the use of opioids. AIM: This work aimed to study the influence of different variants of perioperative anesthesia and analgesia administered during retroperitoneoscopic adrenalectomy in obese patients during the perioperative period. MATERIALS AND METHODS: A randomized study of 94 patients who underwent retroperitoneoscopic adrenalectomy for adrenal neoplasms was performed. Depending on the type of perioperative analgesia, the patients were divided into two groups. In group 1 (n=33), the operation was performed under combined anesthesia based on the low-flow desflurane inhalation; for perioperative analgesia, only systemic opioid administration was provided. In group 2 (n=30), the operation was performed under anesthesia based on low-flow desflurane inhalation in combination with the blockade of the fascial space of the erector muscle. In group 3 (n=31), the operation was performed under anesthesia based on desflurane in combination with drugs for non-opioid analgesia. critical incidents. RESULTS: Surgical intervention of the wound under inhalation anesthesia with ESP blockade (ropivacaine) and a combination of drugs for non-opioid analgesia promotes faster post-anesthetic rehabilitation, effective postoperative analgesia, and fewer complications in the early postoperative period compared with anesthesia using systemic opioid analgesics. This effect contributed to significantly shorter hospitalization of 97 hours for group 2 (95% CI 85-102) (p=0,042) and 94 hours for group 3 (95% CI 82-101) (p=0,039) compared with the 126 hours for group 1 (95% CI 114-135). CONCLUSIONS: Anesthesia based on desflurane in combination with ESP blockade and a multiple drugs for non-opioid anesthesia is an effective method that promotes fast post-anesthesia rehabilitation and shortens the hospitalization period for retroperitoneoscopic adrenalectomy for aldostectomy in the perioperative period.
