Three days after admission, his neutrophil count had increased and laparoscopic cholecystectomy was performed. For one week after the operation, antibiotics were administered; he had an uneventful postoperative recovery. He was discharged on the seventh postoperative day and provided an oral antibiotic.

Infection can be serious in patients with cyclic neutropenia, and it is therefore, important to determine the timing of surgery and to apply appropriate perioperative management with drainage and antibiotic administration.

The radiohybrid (rh) prostate-specific membrane antigen (PSMA)-targeted ligand [

F]Ga-rhPSMA-7 has previously been clinically assessed and demonstrated promising results for PET-imaging of prostate cancer. LGH447 price The ligand is present as a mixture of four stereoisomers ([

F]Ga-rhPSMA-7.1, - 7.2, - 7.3 and - 7.4) and after a preclinical isomer selection process, [

F]Ga-rhPSMA-7.3 has entered formal clinical trials. Here we report on the establishment of a fully automated production process for large-scale production of [

F]Ga-rhPSMA-7/ -7.3 under GMP conditions (EudraLex).

in anhydrous acetonitrile into a reactor containing Ga-rhPSMA ligand and oxalic acid in DMSO.

F-for-

F isotopic exchange at the Silicon-Fluoride Acceptor (SiFA) was performed at room temperature, followed by dilution with buffer and cartridge-based puSMA-targeted ligands. Due to its simplicity, speed and robustness the development of further SiFA-based radiopharmaceuticals is highly promising and can be of far-reaching importance for future theranostic concepts.

This investigation demonstrates that 18F-for-19F isotopic exchange is well suited for the fast, efficient and reliable automated routine production of 18F-labeled PSMA-targeted ligands. Due to its simplicity, speed and robustness the development of further SiFA-based radiopharmaceuticals is highly promising and can be of far-reaching importance for future theranostic concepts.Radiotherapy (RT) is rarely used in the palliative management of muscle-invasive bladder cancer (MIBC). This survey aims to explore current care patterns within the Italian Radiation Oncologist community on this topic. In 2020, the uro-oncological study group of the Italian Association of Radiotherapy and Clinical Oncology (AIRO) conducted a survey evaluating the RT role in advanced MIBC. An electronic questionnaire was administered online to the society members asking for general considerations, patients’ selection, and aim of the treatment, RT schedule and practical consideration, past and future perspective. Sixty-one questionnaires were returned (33% response rate). Most responders (62.30%) declared to work in a Center with a multidisciplinary uro-oncological team, and 8.20% to evaluate more than 20 patients with MIBC/year for palliative RT. Elderly patients were the most frequently evaluated (46.7%) and life expectancy was the most common selection criteria (44.60%). Thirty Gy in 10 fractions (58.9%), whole bladder as GTV (62.5%), PTV isotropic margins of 1.5-2 cm (44.6%) and IMRT/VMAT technique (58.14%) were the most common treatment choices. Patients amenable for bladder palliative RT were most commonly referred by the urologist (43.86%) or the multidisciplinary team (38%). The reported main reasons for the low involvement of radiation oncologist in the management of MIBC patients were low attention to the palliative setting in bladder cancer (37.5%); radiation oncologist not involved in the management of these patients (32.1%); cases not discussed in the multidisciplinary board (26.8%). This survey illustrated the current use of palliative RT for patients with advanced MIBC in Italy and suggested the need for a greater involvement of radiation oncologists in their management.The differences in aortic root geometry associated with various valve-sparing root replacement (VSRR) techniques have not fully been understood. We evaluated the root configuration of current VSRR techniques by developing in vitro test apparatus. Six fresh porcine hearts were used for each model. The aortic root remodeling control group involved replacement of the ascending aorta with diameter reduction of sino-tubular junction (STJ) (C1). The aortic valve reimplantation control group involved replacement of the ascending aorta alone (C2). VSRR included remodeling without (RM) or with annuloplasty (RM + A) and reimplantation with a tube (RI) or a handmade neo-Valsalva graft (RI + V). The root geometry of each model in response to closing hydraulic pressures of 80 and 120 mmHg was investigated using echocardiography. Among the VSRR models, RM yielded the largest aorto-ventricular junction (AVJ), which was similar to those in non-VSRR models [mean AVJ diameter (mm) at 80 mmHg; RM = 25.1 ± 1.5, RM + A = 20.9 ± 0.7, RI = 20.7 ± 0.9, RI + V = 20.8 ± 0.4]. RI + V yielded the largest Valsalva size and largest ratio of Valsalva/AVJ, which was similar to the control group [mean Valsalva diameter (mm) at 80 mmHg; RM = 28.4 ± 1.4, RM + A = 25.8 ± 1.3, RI = 23.6 ± 1.0, RI + V = 30.5 ± 0.8, ratio of Valsalva/AVJ at 80 mmHg; RM = 1.14 ± 0.06, RM + A = 1.24 ± 0.06, RI = 1.15 ± 0.06, RI + V = 1.47 ± 0.05]. The STJ diameter at 80 mmHg was numerically smaller with RM + A (22.4 ± 1.2 mm) than with RM (24.8 ± 2.3 mm, p = 0.11). There were no significant differences in AVJ, Valsalva, or STJ distensibility or ellipticity between procedures. Current modifications, including annuloplasty for remodeling or reimplantation in the setting of neo-Valsalva graft, yield near-physiological root geometries.
