Evaluation of the safety and immunogenicity of a book Matrix-M-adjuvanted nanoparticle coryza vaccine using a quadrivalent seasons flu vaccine throughout older adults: a stage Three or more randomised governed test.
OBJECTIVE The lower airway bacterial microbiome influences carcinogenesis and response to immunotherapy in non-small cell lung cancer (NSCLC). We investigated the association of this microbiome with recurrence in early NSCLC. METHODS Microbiomes of presurgery bronchoalveolar lavage (BAL) and saliva, and resected stage I NSCLC tumor and adjacent lung tissues of 48 patients were examined by 16S gene sequencing. Tumor gene expression was measured by RNA sequencing. RESULTS Spatial relationships of the different biospecimen types was reflected in their microbiomes, with microbiomes of BAL intermediate to those of saliva and lung tissue. BAL and saliva microbiomes were less dissimilar in patients with high α-amylase levels in BAL, indicating oral aspiration as a source of lower airway microbiota. BAL microbiomes of patients with recurrence within 32 months of surgery differed from those without recurrence during ≥32 months of follow-up (n = 18 each), despite no difference for age, sex, smoking history, and tumor histology and grade. The recurrence-associated BAL microbiome signature was present in 16 of the 18 recurrence cases but in only two of the others. Signature presence was associated with shorter recurrence-free survival (log-rank test P less then .001; hazard ratio = 14.5), and greater expression in tumors of genes for cell proliferation and epithelial mesenchymal transition. Immune cellular composition of the tumor microenvironment was not different between patients with and without the signature. CONCLUSIONS Presurgery composition of lower airway microbiome may be associated with recurrence of early NSCLC. This association may reflect an influence of the microbiome on tumor biology. BMS-986235 concentration OBJECTIVE To describe the associations among preoperative characteristics, intraoperative and postoperative factors, and mortality and morbidity after open-heart surgery in patients age ≥80 years. METHODS This retrospective multicenter register study was based on prospectively collected data of all patients age ≥80 years undergoing open-heart surgery in western Denmark between 1999 and 2016. Logistic regression was used to estimate the associations among preoperative characteristics, intraoperative and postoperative factors, and morbidity and mortality. Bonferroni correction was used for multiple comparisons. RESULTS The study population included 2342 patients age ≥80 years undergoing open-heart surgery. We observed an association between severely impaired preoperative renal function and death within 1-year postsurgery (odds ratio [OR], 4.6; 95% confidence interval [CI], 2.7-7.2). Furthermore, renal clearance 180 minutes (OR, 11.6; 95% CI, 4.7-28.5). CONCLUSIONS Our findings emphasize the importance of careful referral regarding the procedural burden for very elderly patients and may provide support for informed patient discussions about prognosis and recovery. BACKGROUND This study evaluated the readability and quality of information regarding arteriovenous (AV) fistula for dialysis on the Internet in the English language. STUDY DESIGN Using Google© search, the keywords "AV Fistula for dialysis" were searched. The top 75 ranking sites were analyzed. One website was excluded due to repetition. Each landing page was assessed independently by two authors (RB, LR) for readability using the Flesch Reading Ease Score (FRES) and Gunning Fog Index (GFI). Web site quality was assessed using the DISCERN instrument. The individual position of the top 15 websites in the search engine ranking order list was noted. The country of origin, organization type and issuance of Health on the Net (HoN) Certification was recorded. Statistical analyses were performed using unpaired t-tests and ANOVA variance. RESULTS The mean GFI score was 9.2 and the mean FRES score was 50.6, indicating poor readability. The mean DISCERN score was 48.4, indicating weak quality of websites. Website quality was influenced by the academic/healthcare organization type (p = 0.012). Organization type was not found to impact GFI and FRES scores. Presence of a HoN Certification was not found to impact the quality of information. The majority of sites originated from the United States (61%). CONCLUSION Our study demonstrates that internet information pertaining to AV fistula for dialysis is of poor quality necessitating improvements to readability and overall website quality to improve the patient experience. Further research into how to improve healthcare web information is needed. BACKGROUND and Purpose Currently, dexmedetomidine versus propofol has primarily been studied in medical and cardiac surgery patients with outcomes indicating safe and effective sedation. The purpose of this study was to assess the efficacy of dexmedetomidine versus propofol for prolonged sedation in trauma and surgical patients. METHODS This was a single-center prospective study conducted in the Trauma/Surgical Intensive Care Unit (ICU) at a Level I academic trauma center. It included patients 18 years of age or older requiring mechanical ventilation who were randomly assigned based on unit bed location to receive either dexmedetomidine or propofol. The primary outcome was duration of mechanical ventilation. Secondary outcomes included mortality; proportion of time in target sedation; incidence of delirium, hypotension, and bradycardia; and ICU and hospital length of stay (LOS). RESULTS A total of 57 patients were included. Baseline characteristics were similar between groups. There was no significant difference in duration of mechanical ventilation (median [IQR]) between the dexmedetomidine (78.5[125] hours) and propofol (105[130] hours; p = 0.15) groups. There was no difference between groups in ICU mortality, ICU and hospital LOS, or incidence of delirium. Safety outcomes were also similar. Patients in the dexmedetomidine group spent a significantly greater percentage of time in target sedation (98[8] %) compared to propofol group (92[10] %; p = 0.02). CONCLUSIONS Our results suggest that, similar to medical and cardiac surgery patients, dexmedetomidine and propofol are safe and effective sedation agents in critically ill trauma and surgical patients; however, dexmedetomidine achieves target sedation better than propofol for this specific population.
