DPCAR’s short- and long-term outcomes are highly diverse, while the causes and prevention of ischemic complications are unclear. To assess oncological, surgical, and hemodynamic outcomes of 40 consecutive DPCARs for pancreatic (n37) and gastric tumors (n3) (2009–2021), retrospective analyses of mortality, morbidity, survival, and hemodynamic consequences after DPCAR were undertaken using case history data, IOUS, and pre- and postoperative CT measurements. In postoperative complications (42.5%), the pancreatic fistula was the most frequent event (27%), 90-day mortality was 7.5. With 27 months median follow-up, median overall (OS) and progression-free survival (PFS) for PDAC were 29 and 18 months, respectively; with 1-, 3-, and 5-years, the OS were 90, 60, and 28%, with an R0-resection rate of 92.5%. Liver and gastric ischemia developed in 0 and 5 (12.5%) cases. Comparison of clinical and vascular geometry data revealed fast adaptation of collateral circulation, insignificant changes in proper hepatic artery diameter, and high risk of ischemic gastropathy if the preoperative diameter of pancreaticoduodenal artery was <2 mm. DP CAR can be performed with acceptable morbidity and survival. OS and RFS in this super-selective cohort were compared to those for resectable cancer. The changes in the postoperative arterial geometry could explain the causes of ischemic complications and determine directions for their prevention.

Introduction. The role of peptides in antinociceptive system regulation has became a subject of interest for scientists worldwide. The first registered peptide analgesic tyrosyl-D-arginyl-phenylalanyl-glycinamide acetate which currently can be used in clinical practice was developed in Russia under the name Taphalgin® (PharmFirma “Sotex”, Russia). The effectiveness and safety of this pharmaceutical in postoperative pain management was evaluated in the all-Russia multicenter prospective observation program NICITA (Non-interventional Clinical Trial of Taphalgin ®).Aim. To analyze the effectiveness and safety of Taphalgin® in postoperative pain management in various surgical fields.Materials and methods. The observational program NICITA included 887 patients including patients with malignant tumors of various locations from 15 study centers in different Russian cities. All patients underwent surgical interventions in various anatomical areas under general, regional and combination anesthesia. The principal scheme of postoperative pain management was based on the multimodal approach which included peptide opioid agonist alongside acetaminophen, cyclooxygenase inhibitors in combination with regional anesthesia or without it. The study also included patients who underwent small-volume surgeries, and pain was managed through Taphalgin® monotherapy with subsequent switch to cyclooxygenase inhibitors. The primary endpoint of the NICITA observational program was response to therapy after the first Taphalgin® administration. Decreased pain syndrome per the numerical rating scale 15–60 min after subcutaneous injection and maintenance of analgesic effect 3 h later were considered treatment response. The secondary endpoints included mean time to analgesia start after administration of the 1st single drug dose (in min), duration of effect, types and frequency of adverse reactions including serious in the central nervous system, pulmonary system, gastrointestinal tract developed during the observational program, as well as patient and research physician satisfaction with pain management. To evaluate the significance of pain intensity change at rest and in motion in time, analysis of variance with repeat measurements was used; for pairwise comparison of two time periods, Student’s t-test for dependent samples was used. The differences were considered significant at p = 0.05.Results. Statistically significant decrease in pain intensity in the total patient group was observed 15 minutes after Taphalgin® administration; it reached its minimum 40 min after the injection (р 0.05). The percentage of patients responding to analgesic therapy with Taphalgin® was 96.5 %. During administration of the drug, insignificant decrease (10–15 mmHg) in arterial blood pressure (1.7 % of cases) and vertigo (1 % of cases) were observed. In some patients, several adverse reactions were observed. Satisfaction with analgesic effect of Taphalgin® was relatively high both in patients and research physicians.Conclusion. Taphalgin® has pronounced analgesic effect and is effective for pain management after surgical interventions of various volumes and injury level. The use of this drug is associated with low rate of adverse reactions and absence of pulmonary depression characterizing opioid agonists. Therefore, Taphalgin® can be recommended for clinical use for postoperative pain management after various types of surgical interventions.

The “vein definition” for locally advanced pancreatic ductal adenocarcinoma (LA PDAC) assumes portal-to-superior mesenteric vein (PV/SMV) unreconstructability due to tumor involvement or occlusion. Radical pancreatectomies with SMV resection without PV/SMV reconstruction are scarcely discussed in the literature. Retrospective analysis of 19 radical pancreatectomies for “low” LA PDAC with SMV and all its tributaries resection without PV/SMV reconstruction has shown zero mortality; overall morbidity—56%; Dindo–Clavien—3–10.5%; R0—rate—82%; mean operative procedure time—355 ± 154 min; mean blood loss—330 ± 170 mL; delayed gastric emptying—25%; and clinically relevant postoperative pancreatic fistula—8%. In three cases, surgery was associated with superior mesenteric (n2) and common hepatic artery (n1) resection. Surgery was completed without vein reconstruction (n13) and with inferior mesenteric-to-splenic anastomosis (n6). There were no cases of liver, gastric, or intestinal ischemia. A specific complication of the SMV resection without reconstruction was 2–3 days-long intestinal edema (48%). Median overall survival was 25 months, and median progression-free survival was 18 months. All the relapses, except two, were distant. The possibility of successful SMV resection without PV/SMV reconstruction can be predicted before surgery by CT-based reconstructions. The mandatory anatomical conditions for the procedure were as follows: (1) preserved SMV-SV confluence; (2) occluded SMV for any reason (tumor or thrombus); (3) well-developed inferior mesenteric vein collaterals with dilated intestinal veins; (4) no right-sided vein collaterals; and (5) no varices in the upper abdomen. Conclusion: “Low” LA PDACs involving SMV with all its tributaries can be radically and safely resected in highly and specifically selected cases without PV/SMV reconstruction with an acceptable survival rate.

The article analyses Russian peasants’ differentiation in the late 19th to early 20th centuries, addressing issues related to transformation of the peasantry's socio-economic standing during the market economy formation period. Combining statistical data analysis and using a multilevel model on peasants’ welfare in the province of Simbirsk, we find that a high level of inequality existed in the region at the time of the census; that inequality within a county contributes more toward income inequality than inequality between counties. Based on different statistical resources, we also plot the graphs and calculate the Gini indices for provinces for which data on the distribution of land, horses, and cows by individual farms are available. Our results do not support Chayanov's hypothesis on the correlation between the number of peasant family members and the amount of land in their possession. Our results indicate that communes were losing their ‘equalising’ function. For most provinces, the Gini index had been rising over time, indicating increasing inequality. Most importantly, this increase occurred in a relatively short period—much faster than in other countries—thereby making Russia more socially and politically vulnerable.

INTRODUCTION: Multimodal analgesia is the main management strategy for postoperative pain. One component of this approach is opioid agonists. OBJECTIVE: Assessment of pain intensity profile after a single administration of the new selective µ1-opioid receptor agonist taphalgin in traumatology and orthopedic patients. MATERIALS AND METHODS: This prospective observational program analyzed data from 100 patients whom were prescribed the drug taphalgin for pain relief after traumatological and orthopedic surgery. All patients were treated with 50 mg dexketoprofen when moderate pain appeared after surgery. If the pain reached moderate or high intensity again, 4 mg of taphalgin was administered subcutaneously and then the change in pain intensity at rest and during movement was observed after 15, 30, 45, 60 min, as well as 2 and 4 h, using numerical rating scale (NRS). In this study physicians’ satisfaction by taphalgin was estimated. Satisfaction was assessed using Likert scale, where 1 — very bad, 2 — unsatisfactory, 3 — satisfactory, 4 — good, 5 — excellent. Repeated measures analysis of variance and dependent samples t-test were used for statistical analysis. The critical level of significance for accepting significant differences was set at 0.05. RESULTS: The average value of pain intensity before drug administration at rest was 5.9 ± 0.5 points and pain in movement was 8.4 ± 0.8 points. After just 15 min, significant pain reduction was achieved to 4.9 ± 0.8 and 7.3 ± 1.1 points (p < 0.001), respectively, after 30 min — to 3.6 ± 1.1 and 5.7 ± 1.1 points (p < 0.001), respectively, and after 60 min — to 2.2 ± 0.8 и 4.2 ± 0.8 points (p < 0.001), respectively. Doctor’s satisfaction with treatment showed that a positive assessment was given in 83 % of cases, and complete dissatisfaction was revealed in 1 % of cases. Impotently, no observations of respiratory depression or postoperative nausea and vomiting syndrome have been recorded. CONCLUSIONS: The drug taphalgin is an effective analgesic for the postoperative period in traumatology and orthopedics.

Aim: To analyze the effectiveness of intravitreal injection of an anti-VEGF agent (ranibizumab) and an dexametazon implant for the intravitreal injection, in real clinical life.Patients and Methods. 137 patients with MO due to retinal venous occlusion were included in the study. Patients were retrospectively divided into groups: patients who received monotherapy with ranibizumab 94 people; and monotherapy with dexamethasone implant — 15 patients; patients who initially were injected with a dexamethasone implant, but due the study transferred to ranibizumab 15 patients; patients who initially received ranibizumab, but then transferred to the dexamethasone implant -13. For the treatment of macular edema were used an anti-VEGF agent — ranibizumab (Lucentis) 0.05 ml (0.5 mg) manufactured by Novartis (Switzerland) or glucocorticosteroid — dexamethasone implant for intravitreal injection of 0.7 mg (Ozurdex) manufactured by Allergan Pharmaceutical Ireland (Ireland). The injections were administered on a pro re nata basis (the presence of macular edema). Standard ophthalmological examination and fluorescent angiography (PAG), optical coherent tomography (OCT), optical coherence tomography angiography (OCT-A) were used. Visual acuity changes (BCVA), central retinal thickness (CRT) and intraocular pressure (IOP) were analyzed depending on the study group (group 1–4), the duration of treatment and the number of injections. Results: In group 1, from 1 to 8 IVVs were performed in 24 months, an average of 3.77. In group 2, from 1 to 4 intravitreal injections were performed in 24 months, an average of 1.37. In group 3, from 1 to 2 of intravitreal injections Ozurdex and from 1 to 4 intravitreal injections of ranibizumab for 24 months. In group 4, from 1 to 4 intravitreal injections of anti-VEGF drug and from 1 to 4 intravitreal dexamethasone implant were performed in 24 months of follow-up. Monotherapy with the Ozurdex drug (12 months) had the most stable effect, with a relapse of the process, repeated injections were required, conducted only in 3 out of 15 patients. Conclusion: In real clinical practice, the dexamethasone implant showed a good safety profile and high efficacy in the resorption of macular edema in patients with retinal vein occlusion, which corresponds to the clinical trials that was made earlier.
