Solid organ transplantation (SOT) implies immunosuppression and frequent health care contact. Our aim was to compare the characteristics of patients with infective endocarditis (IE) and SOT against those without SOT.<br /><br /> We used data from the Spanish Collaboration on Endocarditis during the period 2008-2018.<br /><br /> We identified 4794 cases ofIE, 85 (1.8%) in SOT (56 kidney, 18 liver, 8 heart, 3 lung). Thirteen patients with other transplantation types (bone marrow, hematopoietic precursors, and cornea) were excluded from the analysis. Compared with patients without SOT, patients with SOT had lower median age (61 vs. 69 years, p&lt;0.001), more comorbidities (mean age-adjusted Charlson index 5.7±2.9 vs. 4.9±2.9, p=0.004), a lower prevalence of native valvular heart disease (29.4 vs. 45.4%, p=0.003), more in-hospital and healthcare-related IE (70.5% vs. 36.3%, p&lt;0.001) and staphylococcal etiology (57.7% vs. 39.7%, p=0.001). Patients with SOT had more frequent kidney function worsening (47.1% vs. 34.6%, p=0.02), septic shock (25.9% vs. 12.1 %, p&lt;0.001), sepsis (27.1% vs. 17.2%, p=0.02), and less surgery indication (54.1% vs 66.3%, p=0.02) and surgery (32.9% vs. 46.3%, p=0.01) than patients without SOT. There were no significant differences in mortality inhospital (30.6% SOT vs. 25.6% without SOT, p=0.31), 1-year (38.8% SOT vs. 31.9% without SOT, p=0.18).<br /><br /> Most IE in SOT recipients are nosocomial and over 70% are health care-related. Half have previously normal heart valves and almost 60% are due to Staphylococcus spp. infections. Mortality seems to be similar to non-SOT counterparts.<br /><br />Most IE in SOT recipients are nosocomial and over 70% are health care-related.

The crises with escalating overdose mortality in several countries, particularly overdoses related to opioids, have drawn attention to life course shifts in the burdens of substance use. Overdose mortality rates for individuals in midlife have considerably outpaced those of adolescents and individuals in early adulthood. These diverging life course trends are occurring not only in the United States, but in other countries with growing overdose problems as well. The future of effective policy and practice depend upon evidence and analyses that adapt to emerging data on shifting life course trends in drug related mortality. Within this manuscript, we consider a range of theoretical possibilities on the divergence of midlife drug mortality trends from those of young people for the purpose of outlining an agenda for future research and practice. Specifically, we consider the following theoretical approaches to move research forward in this area Changes in Medical Context hypothesis; Emergent Comorbidities hypothesis; Cohort hypothesis; Generational Forgetting hypothesis; Legal Regulation hypothesis; Strength of Life Course Bonds hypothesis; Deepening Inequality hypothesis; Measurement Reliability hypothesis. These theoretical frameworks attend specifically to the overdose crisis but extend to other aspects of substance use. Beyond setting an agenda for research by providing empirically verifiable hypotheses, this manuscript also identifies future directions in policy and practice that are attentive to life course trends.<br /><br /> Reported 4Kscore thresholds used to differentiate between patients with and without high-grade prostate cancer (CaP) were variable. Patients with 4Kscore results &lt;7.5% have been proven to be at low risk of carrying high-grade CaP. This study employed a meta-analysis approach in order to assess the diagnostic accuracy of the 4Kscore as a means of detecting high-grade CaP in prostate biopsy samples using cutoff values of 7.5% to 10%.<br /><br /> Relevant studies published as of December 2019 were identified via searching PubMed, Embase, and Cochrane Library. Data pertaining to 4Kscore diagnostic accuracy were then extracted from these studies and utilized for the calculation of pooled sensitivity , specificity , diagnostic odds ratio , and area under the curve values relating to high-grade CaP diagnosis.<br /><br /> In total, 9 studies incorporating 1,689 high-grade CaP patients were included in our meta-analysis.

Clinical studies to evaluated novel treatments are challenging given the rarity of these patients. Therefore, we sought to evaluate PD-L1 staining on metastatic and postchemotherapy viable testicular GCTs as a surrogate for potential benefit for immunotherapy targeting the PD-1/PD-L1 axis.<br /><br /> Ethics research committee approval for this retrospective study was obtained by four participating institutions (CHU de Québec, St. Joseph's Health Care, Halifax Health Science Centre, Johannes Gutenberg University). Patients with viable metastatic testicular GCTs pathology samples were included. Patients with pure teratoma were excluded. PD-L1 staining with the 22C3 clone was evaluated on samples with &gt;100 viable tumor cells using the combined positive score (CPS).<br /><br /> From 51 patients identified at participating institutions, 24 postchemotherapy and 18 chemotherapy-naive metastatic samples were available for therapy naïve-samples, PD-L1 expression was higher in metastatic samples versus testicular samples (mean CPS 68.8 vs. 39.8, P = 0.02). This was also seen in matched chemotherapy-naïve samples (mean CPS 77.9 vs. 33.1, P = 0.01).<br /><br /> Our results suggest that most patients with refractory GCTs postchemotherapy will not benefit from PD-1/PD-L1 immunotherapy. However, the high PD-L1 expression in patients with predominant or pure seminoma post-chemotherapy suggests this may represent a subgroup for whom further trials may be considered.<br /><br />Our results suggest that most patients with refractory GCTs postchemotherapy will not benefit from PD-1/PD-L1 immunotherapy.
