Abstract
AIMS OF THE STUDY The impact of coronavirus disease 2019 (COVID-19) on patients listed for solid organ transplantation has not been systematically investigated to date. Thus, we assessed occurrence and effects of infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on patients on the Swiss national waiting list for solid organ transplantation. METHODS Patient data were retrospectively extracted from the Swiss Organ Allocation System (SOAS). From 16 March to 31 May 2020, we included all patients listed for solid organ transplantation on the Swiss national waiting list who were tested positive for SARS-CoV-2. Severity of COVID-19 was categorised as follows: stage I, mild symptoms; stage II, moderate to severe symptoms; stage III, critical symptoms; stage IV, death. We compared the incidence rate (laboratory-confirmed cases of SARS-CoV-2), the hospital admission rate (number of admissions of SARS-CoV-2-positive individuals), and the case fatality rate (number of deaths of SARS-CoV-2-positive individuals) in our study population with the general Swiss population during the study period, calculating age-adjusted standardised incidence ratios and standardised mortality ratios, with 95% confidence intervals (CIs). RESULTS A total of 1439 patients were registered on the Swiss national solid organ transplantation waiting list on 31 May 31 2020. Twenty-four (1.7%) waiting list patients were reported to test positive for SARS-CoV-2 in the study period. The median age was 56 years (interquartile range 45.3–65.8), and 14 (58%) were male. Of all patients tested positive for SARS-CoV-2, two patients were asymptomatic, 14 (58%) presented in COVID-19 stage I, 3 (13%) in stage II, and 5 (21%) in stage III. Eight patients (33%) were admitted to hospital, four (17%) required intensive care, and three (13%) mechanical ventilation. Twenty-two patients (92%) of all those infected recovered, but two male patients aged >65 years with multiple comorbidities died in hospital from respiratory failure. Comparing our study population with the general Swiss population, the age-adjusted standardised incidence ratio was 4.1 (95% CI 2.7–6.0). CONCLUSION The overall rate of SARS-CoV-2 infections in candidates awaiting solid organ transplantation was four times higher than in the Swiss general population; however, the frequency of testing likely played a role. Given the small sample size of affected patients, conclusions have to be drawn cautiously and results need verification in larger cohorts.

Abstract
UNLABELLED Abaloparatide, a novel PTH1 receptor agonist, increased bone formation in osteopenic ovariectomized cynomolgus monkeys while increasing cortical and trabecular bone mass. Abaloparatide increased bone strength and maintained or enhanced bone mass-strength relationships, indicating preserved or improved bone quality. INTRODUCTION Abaloparatide is a selective PTH1R activator that is approved for the treatment of postmenopausal osteoporosis. The effects of 16 months of abaloparatide administration on bone formation, resorption, density, and strength were assessed in adult ovariectomized (OVX) cynomolgus monkeys (cynos). METHODS Sixty-five 9-18-year-old female cynos underwent OVX surgery, and 15 similar cynos underwent sham surgery. After a 9-month period without treatments, OVX cynos were allocated to four groups that received 16 months of daily s.c. injections with either vehicle (n = 17) or abaloparatide (0.2, 1, or 5 μg/kg/day; n = 16/dose level), while Sham controls received s.c. vehicle (n = 15). Bone densitometry (DXA, pQCT, micro-CT), qualitative bone histology, serum calcium, bone turnover markers, bone histomorphometry, and bone strength were among the key measures assessed. RESULTS At the end of the 9-month post-surgical bone depletion period, just prior to the treatment phase, the OVX groups exhibited increased bone turnover markers and decreased bone mass compared with sham controls. Abaloparatide administration to OVX cynos led to increased bone formation parameters, including serum P1NP and endocortical bone formation rate. Abaloparatide administration did not influence serum calcium levels, bone resorption markers, cortical porosity, or eroded surfaces. Abaloparatide increased bone mass at the whole body, lumbar spine, tibial diaphysis, femoral neck, and femoral trochanter. Abaloparatide administration was associated with greater lumbar vertebral strength, and had no adverse effects on bone mass-strength relationships for the vertebrae, femoral neck, femoral diaphysis, or humeral cortical beams. CONCLUSIONS Abaloparatide administration was associated with increases in bone formation, bone mass and bone strength, and with maintenance of bone quality in OVX cynos, without increases in serum calcium or bone resorption parameters.

Abstract
Background and Study Aims There is a paucity of literature on beginners' training and on its connection with patient safety for transforaminal epidural steroid injections (TFESIs). This study retrospectively assessed the learning curves and associated complications of neurosurgery residents never previously exposed to TFESI and compared them with experienced board-certified faculty neurosurgeons (BCFNs).
Material and Methods Procedure time in minutes, dose-area product (DAP) in cGy*cm2, periprocedural observations, and complications in 354 TFESIs for radicular pain secondary to lumbar disk herniation or lumbar spinal stenosis were extracted from operative notes and the electronic infiltration logbook in the per-injection format. Learning curves for 238 residents and 116 BCFN TFESIs in terms of procedure time and DAP were estimated using monotone regression.
Results Residents' TFESI procedure time and DAP reached BCFN level (4.7 minutes and 140.2 Gy*cm2) after 67 and 68 cases, respectively. Residents' TFESIs were unsuccessful in 1.7%, mostly for severe obesity and hypertrophied facet joints, but no severe complications were noted. Obesity, however, did not result in increased procedure times or radiation exposure in general. Residents were faster and required less fluoroscopy in TFESI of the upper lumbar nerve roots than for L5 or S1 in particular.
Conclusion The residents' learning curve for TFESIs in terms of procedure time and radiation exposure can be overcome safely after < 70 TFESIs. An outcome analysis correlating to the interventionalist's training level would be worth investigating in future studies.

Abstract
Background Magnetic resonance imaging (MRI) of the prostate is considered to be the most precise noninvasive staging modality for localized prostate cancer. Multiparametric MRI (mpMRI) dynamic sequences have recently been shown to further increase the accuracy of staging relative to morphological imaging alone. Correct radiological staging, particularly the detection of extraprostatic disease extension, is of paramount importance for target volume definition and dose prescription in highly-conformal curative radiotherapy (RT); in addition, it may affect the risk-adapted duration of additional antihormonal therapy. The purpose of our study was to analyze the impact of mpMRI-based tumor staging in patients undergoing primary RT for prostate cancer. Methods A total of 122 patients admitted for primary RT for prostate cancer were retrospectively analyzed regarding initial clinical and computed tomography-based staging in comparison with mpMRI staging. Both tumor stage shifts and overall risk group shifts, including prostate-specific antigen (PSA) level and the Gleason score, were assessed. Potential risk factors for upstaging were tested in a multivariate analysis. Finally, the impact of mpMRI-based staging shift on prostate RT and antihormonal therapy was evaluated. Results Overall, tumor stage shift occurred in 55.7% of patients after mpMRI. Upstaging was most prominent in patients showing high-risk serum PSA levels (73%), but was also substantial in patients presenting with low-risk PSA levels (50%) and low-risk Gleason scores (45.2%). Risk group changes occurred in 28.7% of the patients with consequent treatment adaptations regarding target volume delineation and duration of androgen deprivation therapy. High PSA levels were found to be a significant risk factor for tumor upstaging and newly diagnosed seminal vesicle infiltration assessed using mpMRI. Conclusions Our findings suggest that mpMRI of the prostate leads to substantial tumor upstaging, and can considerably affect treatment decisions in all patient groups undergoing risk-adapted curative RT for prostate cancer.

Abstract
Eosinophils are recruited to the airways during allergic reactions, but animal models have shown that their mere presence is not sufficient for the development of bronchopulmonary hyperreactivity. Other factors, such as immunoglobulin (Ig)E, seem to be required. Using mice selected for the production of large amounts of IgE, the effects of antibody neutralization of IgE on antigen-induced lung recruitment of eosinophils and induction of bronchopulmonary hyperreactivity and of other indicators of inflammation were studied. A monoclonal non-anaphylactogenic rat anti-mouse IgE (mAb1-5), given within 24 h of the challenge with antigen, reduced tissue eosinophilia, the recruitment of IgE-bearing cells identified as basophils, mucous cell metaplasia, anaphylactic bronchoconstriction and bronchopulmonary hyperreactivity. mAb1-5 inhibited interleukin (IL)4 titres in the bronchoalveolar lavage fluid, but not those of I1-5. Inhibition by mAb1-5 may result from competitive displacement of immunoglobulin E from its different receptors, thus preventing cell stimulation. Moreover, the inhibition of the massive recruitment of immunoglobulin E-bearing basophils into the lungs within hours after challenge and of interleukin4 production by mAb1-5 may be important factors leading to the reduction of pulmonary eosinophilia and bronchopulmonary hyperreactivity. Thus, immunoglobulin (Ig)E and allergic IgE-bearing cells seem to play an essential role in the initial development of the late allergic airway responses.

Abstract
Inflammatory-cell infiltration and epithelial modifications are prominent lesions of the bronchial mucosa in asthma and in experimental allergic bronchopulmonary inflammation. However, the recruitment of inflammatory cells and their relationship to the epithelial modifications and to functional alterations such as bronchopulmonary hyperreactivity (BHR) are less known. We studied the mechanisms of antigen-dependent inflammatory-cell recruitment to the lungs and the associated lesions and their relationship using drug- and antibody-dependent cell-depletion procedures. A single intranasal ovalbumin challenge in BP2 mice was found to induce hyperreactivity within 1 h after challenge, followed by the massive infiltration of immunoglobulin (Ig)E-bearing polymorphonuclear leukocytes (PMN), and eosinophils, and by a mucous-cell metaplasia of the bronchiolar epithelium. Similarly challenged BALB/c mice did not exhibit BHR, despite a moderate recruitment of inflammatory cells and mucous-cell metaplasia. Inflammatory-cell recruitment, mucous-cell metaplasia, and BHR were prevented by prior antibody-dependent depletion of CD3(+) lymphocytes and partially inhibited by the depletion of CD4(+) lymphocytes. Treatment with the granulocytopenic drug vinblastine before challenge completely abolished the recruitment of granulocytes without affecting the antigen-induced mucous-cell metaplasia. In this study two new key elements of the murine model of allergic pulmonary inflammation are described: the recruitment of IgE-bearing PMN between 3 and 72 h after challenge, and the dissociation between granulocytes and mucous-cell metaplasia.
