00; 95%CI 0.98-1.02). The overall rate of pathologic nodal upstaging was 19%. Modeled as a continuous variable, greater than 7 lymph nodes assessed at time of resection was significantly associated with nodal upstaging in multivariable regression (odds ratio [OR] 1.03; 95%CI 1.01-1.06). Conclusion In this study, there was no clear difference in survival based on increasing the number of lymph nodes assessed during lobectomy for limited stage SCLC. However, the number of retrieved lymph nodes was associated with pathologic nodal upstaging. Therefore, patients may benefit from retrieval of greater than 7 lymph nodes during lobectomy for SCLC.Background Serious Mental Illness (SMI), defined as a mental disorder causing functional impairment, affects 9.8 million Americans. SMI correlates with earlier onset, more extensive cardiac disease, and reduced life expectancy by 25 years. The impact of SMI on patients undergoing cardiac surgery has not been extensively studied. We hypothesized patients with SMI have worse cardiac surgery outcomes. Methods Using our institution's Society of Thoracic Surgeons database of 16,781 cardiac operations (2002-2017), a total of 1,445 patients (8.7%) were identified with SMI, and stratified into anxiety, mood disorders, and psychosis. The risk-adjusted impact on morbidity and mortality were evaluated using multivariable regression. Results Patients with SMI were more often female, younger, and had more comorbid disease. SMI patients were more likely to have had previous cardiac surgery and require urgent/emergent procedures (both p less then 0.05). Among specific SMI diagnoses, patients with psychosis had worse outcomes compared to the general population, with higher operative mortality (9.1% vs 4.2%, p=0.0001), major morbidity (30.4% vs 15.8%, p less then 0.0001), and cost ($50,211 vs $38,820, p less then 0.0001). After multivariable risk adjustment, SMI and psychosis remained independently associated with composite mortality and major morbidity (OR 1.21, p=0.012 and 1.68, p=0.0003, respectively). Conclusions Serious Mental Illness is independently associated with morbidity and mortality after cardiac surgery. SMI patients, especially the subset with psychosis, are complicated, high-risk, and resource-consuming.

The development of carriers, e.g., polymers, lipids, peptides, antibodies, aptamers, small molecules, exosome and red blood cells, is crucial for the systemic delivery of siRNA. Cell-specific targeting ligands in the nano-carriers can improve the pharmacokinetics, biodistribution, and selectivity of siRNA therapeutics. The safety, effectiveness, quality and prosperity of production and manufacturing are important considerations for selecting the appropriate siRNA carriers. Efficacy of systemic delivery of siRNA requires considerations of trafficking through the blood, off-target effects, innate immune response and endosomal escape avoiding lysosomal degradation for entering into RNAi process. Multifunctional nanocarriers with stimuli-responsive properties such as pH, magnetic and photo-sensitive segments can enhance the efficacy of siRNA delivery. The improved preclinical characterization of suitable siRNA drugs, good laboratory practice, that reduce the differences between in vitro and in vivo results may increase the success of siRNA drugs in clinical settings.Since 2002, published miRNAs have been collected and named by the online repository miRBase. However, with 11 000 annual publications this has become challenging. Recently, four specialized miRNA databases were published, addressing particular needs for diverse scientific communities. This development provides major opportunities for the future of miRNA annotation and nomenclature.How does the folding of the genome relate to the regulation of gene expression? Using fly embryos and quantitative live imaging, a recent study by Yokoshi et al. reveals that the answer might depend on whether enhancer-promoter communication occurs inside or in-between topological domains.Lantibiotic salivaricins are polycyclic peptides containing lanthionine and/or β-methyllanthionine residues produced by certain strains of Streptococcus salivarius, which almost exclusively reside in the human oral cavity. The importance of these molecules stems from their antimicrobial activity towards relevant oral pathogens which has so far been applied through the development of salivaricin-producing probiotic strains. However, salivaricins may also prove to be of great value in the development of new and novel antibacterial therapies in this era of emerging antibiotic resistance. In this review, we describe the biosynthesis, antimicrobial activity, structure, and mode of action of the lantibiotic salivaricins characterized to date. Moreover, we also provide an expert opinion and suggestions for future development of this important field of microbiology.Indole is a signalling molecule produced by many bacterial species and involved in intraspecies, interspecies, and interkingdom signalling. Despite the increasing volume of research published in this area, many aspects of indole signalling remain enigmatic. There is disagreement over the mechanism of indole import and export and no clearly defined target through which its effects are exerted. Progress is hindered further by the confused and sometimes contradictory body of indole research literature. We explore the reasons behind this lack of consistency and speculate whether the discovery of a new, pulse mode of indole signalling, together with a move away from the idea of a conventional protein target, might help to overcome these problems and enable the field to move forward.Viral defective interfering particles (DIPs) were intensely studied several decades ago but research waned leaving open many critical questions. New technologies and other advances led to a resurgence in DIP studies for negative-strand RNA viruses. While DIPs have long been recognized, their exact contribution to the outcome of acute or persistent viral infections has remained elusive. Recent studies have identified defective viral genomes (DVGs) in human infections, including respiratory syncytial virus and influenza, and growing evidence indicates that DVGs influence disease severity and may contribute to viral persistence. Further, several studies have advanced our understanding of key viral and host factors that regulate DIP formation and activity. Here we review these discoveries and highlight key questions moving forward.
