Spinal cord injury (SCI) is associated with a reduced level of physical activity, deterioration of patient body composition, metabolic profile, quality of life, and psychological functioning. As a result, risk of cardiovascular disease (CVD) increases and CVD-related death occurs at an earlier age than in individuals without SCI. Regular participation in exercise has been shown to exert beneficial effects also in patients with SCI. In this review, we analyze and discuss the effects of regular exercise training in SCI on cardiovascular function, autonomic function of the cardiovascular system, arterial stiffness, metabolism, inflammation, and gene expression.The coronavirus disease-2019 (COVID-19) pandemic containment and mitigation strategies may lead to excessive physical inactivity and sedentary behavior, drastically impacting cardiorespiratory fitness and overall health. It is urgent to safely find ways to sit less and move more.

The authors describe the newly proposed synthesis technique for the gallium-68 (Ga-68)-labeled tracer ([Ga]Ga-PSMA-HBED-CC) for imaging expression of the prostate-specific membrane antigen (PSMA). An effort was applied to design the lyophilized cold kit (isoPROtrace-11) as a time-saving technique resulting in increased radiochemical yields.

The initial material for labeling was obtained from a Ge/Ga-generator. For labeling with the lyophilized cold kit isoPROtrace-11, 2.5 ml 0.1 M HCl of the middle Ga-68 elution fraction were added to the kit, shook for dissolving the vial's contents and kept for 5 minutes at room temperature. A systematic comparison was carried out between results obtained with the cold kit technique and with previously used Modular-Lab module concerning the radiochemical yield, purity, and the time of producing.

Automated module-involved synthesis of [Ga]Ga-PSMA-HBED- CC resulted in a radiochemical yield of 84.2 ± 6.3% and purity of >95% after 25 minutes. The room temperature cold kit gave a radiochemical yield of >98% and purity of >95% after 5 minutes.

Using the kit method reduced the labeling time. The cold kit method increased production efficiency because less of the eluted Ga-68 was wasted.

To meet the strong demand for [Ga]Ga-PSMA-11, we aimed to optimize an automated radiolabeling process by evaluating the influence of different key parameters on radiochemical purity and radiochemical yield.

The radiosynthesis of [Ga]Ga PSMA-11 was performed using a Trasis MiniAio synthesizer and a Ge/Ga GalliaPharm generator supplied by Eckert & Ziegler, Berlin, Germany. Optimized labeling parameters were evaluated by variation of sodium acetate concentrations and temperature of radiolabeling as well as the purification process.

For each condition tested, radiochemical purity was higher than 99% in the final vial without batch failure, indicating a robust and fast radiosynthesis process. Radiosynthesis without the solid phase extraction purification process at room temperature in less than 5 min resulted in a radiolabeling efficiency of over 99% and remained stable at least 4 h without manual processing to limit operator radiation exposure.

The procedure was completely automated and provided a high radiochemical yield. It can be performed several times a day, facilitating the clinical demand of this radiopharmaceutical.

The aim of this study was to characterize national variation in radionuclide calibrator activity response to a single National Institute of Standards and Technology (NIST) traceable reference Ge source used as a surrogate for F at clinical PET centres in England using National Physical Laboratory approved techniques.

Readings from 20 instruments at 13 centres using local F and Ge factor settings were recorded with the source located in vial and syringe positions. Ten repeat measurements were conducted to investigate repeatability using % coefficient of variability (COV). Comparison ratios to investigate accuracy were made between calibrator responses and decay-corrected NISTref reference activity for syringe and vial position measurements.

The maximum %COV was 0.79%, while 90, 95 and 80% of calibrators conformed to 5% accuracy for F syringe, Ge syringe and Ge vial position readings, respectively. We revealed a trend towards reduced bias in measurements using Veenstra devices for F and using Capintec devices for Ge factor settings.

This study demonstrated good repeatability in local device measurements. In total, 70% of English calibrators tested and 88% of all measurements performed achieved 5% accuracy. While statistically significant bias was exhibited between different vendor equipment dependent upon radioisotope selected, our study recommends regular traceability checks for optimum instrument performance conducted within National Metrology Institutes guidelines.

The aim of the study was to evaluate diagnostic performance of FDG PET-CT in suspected recurrence of carcinoma esophagus after curative-intent surgical resection and impact of FDG PET-CT on intended management.

This was retrospective study of patients with clinical or radiological suspicion of recurrent esophageal carcinoma who were referred for PET-CT from January 2006 to December 2017. Diagnostic performance of PET-CT was evaluated for disease recurrence and its impact on management decisions. PET-CT findings were confirmed with tissue diagnosis. When tissue diagnosis was not available clinical and radiological follow-up was used as reference standard.

Relevant clinical data were available in 68 patients which were considered for analysis. In 91% (62/68) patients FDG PET-CT findings were suggestive of disease recurrence. Histopathological confirmation was available in 43 patients, whereas in remaining patients recurrence was confirmed by radiological and clinical follow-up. Forty percent (28/68) patients were detected with distant metastases.
