Background Radiotherapy is an emerging treatment strategy for nodal oligorecurrent prostate cancer (PCa) patients. However, large heterogeneities exist in the RT regimens used, with series reporting the use of elective nodal radiotherapy (ENRT) strategies and others the delivery of focal treatments to the relapsing nodes with Stereotactic Body Radiotherapy (SBRT). In this systematic review of the literature we compared the oncological outcomes and toxicity of the different RT regimens for nodal oligorecurrent PCa patients, with the aim of defining the optimal RT target volume in this setting.Methods We performed a systemic search on the Pubmed database to identify articles reporting on the use of ENRT or SBRT for oligometastatic PCa with nodal recurrence.Results Twenty-two articles were analyzed, including four prospective phase II trials (3 with SBRT and 1 with ENRT). Focal SBRT, delivered with an involved node, involved site, and involved field modality, was the most commonly used strategy with 2-year progression-free survival (PFS) rates ranging from 16 to 58% and a very low toxicity profile. Improved PFS rates were observed with ENRT strategies (52-80% at 3 years) compared to focal SBRT, despite a slightly higher toxicity rate. One ongoing randomized phase II trial is comparing both modalities in patients with nodal oligorecurrent PCa.Conclusions With a large variability in patterns of practice, the optimal RT strategy remains to be determined in the setting of nodal oligorecurrent PCa. Ongoing randomized trials and advances in translational research will help to shed light on the best management for these patients..The suprachiasmatic nucleus (SCN) drives circadian rhythms in locomotion through coupled, single-cell oscillations. Global genetic deletion of the neuropeptide Vip or its receptor Vipr2 results in profound deficits in daily synchrony among SCN cells and daily rhythms in locomotor behavior and glucocorticoid secretion. To test whether this phenotype depends on vasoactive intestinal polypeptide (VIP) neurons in the SCN, we ablated VIP SCN neurons in vivo in adult male mice through Caspase3-mediated induction of the apoptotic pathway in cre-expressing VIP neurons. We found that ablation of VIP SCN neurons in adult mice caused a phenotype distinct from Vip- and Vipr2-null mice. Mice lacking VIP neurons retained rhythmic locomotor activity with a shortened circadian period, more variable onsets, and decreased duration of daily activity. Quizartinib Target Protein Ligand chemical Circadian hormonal outputs, specifically corticosterone rhythms, were severely dampened. In contrast, deletion of neonatal SCN VIP neurons dramatically reduced circadian gene expression in the cultured SCN, mimicking the effects of global deletion of Vip or Vipr2. These results suggest that SCN VIP neurons play a role in lengthening circadian period and stimulating the daily surge in glucocorticoids in adults and in synchronizing and sustaining daily rhythms among cells in the developing SCN.Background Several studies have investigated the role of PAI-1 4G/5G and ACE I/D polymorphisms in the etiology of pediatric sepsis, but the results are inconsistent. We performed a meta-analysis to assess for any associations. Methods A comprehensive literature search on PubMed, web of science, and CNKI database was conducted up to April 15, 2020. Results There were twelve case-control studies involving seven studies with 860 cases and 1144 controls on PA-1 4G/5G and five studies with 1602 cases and 1585 controls on ACE I/D. PAI-1 4G/5G and ACE I/D polymorphisms were associated with an increased risk of pediatric sepsis in the global population. Stratified analysis by ethnicity showed a significant association in the Caucasians children. Conclusions The meta-analysis suggests that the PAI-1 4G/5G and ACE I/D polymorphisms may be risk factors for development of pediatric sepsis in the global population.Introduction On 15-16 November 2019, the Skandion Clinic in Sweden hosted the first Nordic workshop on 'Patients' perspective in proton beam therapy'. The workshop was conducted to describe and compare the patient care in PBT clinics in the Nordic countries and to initiate a collaboration, with the target to ensure patient participation and reduce the risk of inequity of access by lowering the barriers for accepting PBT in a distant clinic. The overarching aim of this workshop was to describe and compare the use of patients' perspectives in the Nordic PBT clinics.Material and Methods Twelve participants attended the workshop, representing Denmark, Norway and Sweden. The participants were registered nurses working in patient care, researchers, physicist and leaders of the Skandion Clinic.Results The consensus of the workshop was that systematic use of patient experiences on individual and group level is essential for developing clinical practice and understanding the overall effects of PBT. A difference in how the Nordic countries use patient experiences in clinical practise was found. The importance of lowering the barriers for participation in national proton trials and proton treatment were emphasized, however, there is a lack of knowledge about individual and organizational barriers to accepting PBT, and further research is therefore needed.Conclusion Collaboration between the Nordic countries regarding patients' perspectives in the context of PBT is of importance to compare national differences as well as to find similarities, but most importantly to learn from each other and to improve patient care. Nordic collaboration with focus on systematic collection of patient-reported outcomes in the context of PBT is unique. Collaboration in research offers the possibility to increase the inclusion of patients' perspectives in study protocols.Introduction Duodenal eosinophilia is a key feature of functional dyspepsia, particularly in those with early satiety. Duodenal eosinophilia is also recognised in coeliac disease, although its relevance to symptoms is not understood. We aimed to determine if duodenal eosinophilia is present in patients with coeliac disease presenting with dyspepsia, and whether other histological characteristics were associated with clinical features on presentation.Methods The coeliac study population comprised 61 patients with a new presentation of coeliac disease to a single centre from 2003 to 2013. A standard symptom assessment was documented for all patients. The control population (55 adults) presenting for endoscopy without coeliac disease was drawn from the same centre with similar demographics for age and gender. Duodenal biopsies from both groups were assessed for eosinophil counts and histological features.Results Dyspepsia was present in 18.0% of coeliac patients and early satiety in 24.6%. The eosinophil counts were significantly higher in the stomach (12.
