RESUMO
The cross section of the process e^{+}e^{-}âπ^{+}π^{-} has been measured in the center-of-mass energy range from 0.32 to 1.2 GeV with the CMD-3 detector at the electron-positron collider VEPP-2000. The measurement is based on an integrated luminosity of about 88 pb^{-1}, of which 62 pb^{-1} represent a complete dataset collected by CMD-3 at center-of-mass energies below 1 GeV. In the dominant region near the ρ resonance a systematic uncertainty of 0.7% was achieved. The implications of the presented results for the evaluation of the hadronic contribution to the anomalous magnetic moment of the muon are discussed.
RESUMO
AIM: To evaluate the efficacy and safety of NefroBest-N in patients undergoing to the radical cystectomy with neobladder formation. MATERIALS AND METHODS: A total of 60 patients with invasive bladder cancer aged 56 to 75 years, treated at A.I. Burnazyan SRC FMBC and at the M.A. Podgorbunsky Kuzbass linical Hospital of Emergency Medical Care in 2022, were included in randomized multicenter parallel group study. All patients underwent radical cystectomy with a formation of Studer neobladder. The main group included those who received the drug NefroBest-N, 1 capsule 2 times a day for 90 days. In the control group, only symptomatic therapy according to current standards was administered. The study consisted of a screening period of up to 4 days (Visit 1) and a period of 90+2 days to evaluate the efficiency of therapy, including 3 visits: day 14 (Visit 2), 30+2 days (Visit 3) and 90+2 days (Visit 4). Laboratory examination and imaging studies included biochemistry panel (urea, creatinine, K, Na, CRP), urinalysis (presence of mucus, leukocytes), urine culture (bacteriuria), physical examination, renal and neobladder ultrasound with determination of postvoid residual volume. In addition, evaluation of the quality of life was also performed. RESULTS: Evaluation of efficacy and safety of NefroBest-N was carried out. Administration of NefroBest-N resulted in a more rapid improvement of urinalysis, including a significant decrease in severity of leukocyturia and amount of mucus. In addition, degree of bacteriuria was reduced according to the urine culture. The quality of life was also improved. CONCLUSION: NefroBest-N has a favorable efficacy and safety profile. According to our experience, NefroBest-N significantly reduces recovery time and improves the quality of life of patients who have undergone radical cystectomy with a neobladder formation.
