Background: There is an important need to develop noninvasive biomarkers to detect disease in premature neonates. Our objective was to determine if salivary genomic analysis provides novel information about neonatal expression of developmental genes. Methods: Saliva (50–200 μL) was prospectively collected from 5 premature infants at 5 time points: before, starting, and advancing enteral nutrition; at the introduction of oral feeds; and at advanced oral feeds. Salivary RNA was extracted, amplified, and hybridized onto whole-genomic microarrays. Results: Bioinformatics analyses identified 9286 gene transcripts with statistically significant gene expression changes across individuals over time. Of these genes, 3522 (37.9%) were downregulated, and 5764 (62.1%) were upregulated. Gene expression changes were highly associated with developmental pathways. Significantly downregulated expression was seen in embryonic development, connective tissue development and function, hematologic system development and function, and survival of the organism (10−14 < P < 10−3). Conversely, genes associated with behavior, nervous system development, tissue development, organ development, and digestive system development were significantly upregulated (10−11 < P < 10−2). Conclusions: Comparative genomic salivary analyses provide robust, comprehensive, real-time information regarding nearly all organs and tissues in the developing preterm infant. This innovative and noninvasive technique represents a new approach for monitoring health, disease, and development in this vulnerable patient population. By comparing these data in healthy infants with data from infants who develop medical complications, we expect to identify new biomarkers that will ultimately improve newborn care.

SUMMARY The concurrence of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) has been reported infrequently. Eleven patients are described here with both RA and SLE, in whom the diagnoses were separated by one to 24 years. Because of the difficulty in diagnosing RA occurring subsequent to SLE, only patients with classical RA as their initial diagnosis were included. Further difficulties arise because arthritis is common to both diseases and may be deforming in SLE, antinuclear antibodies (ANA) are not uncommon in RA, and rheumatoid factor (RF) may be seen in SLE. Nonetheless, judicious application of the American Rheumatism Association (ARA) criteria allows both diagnoses to be made in the individual patient. In our patients there was erosive arthritis in nine, rheumatoid nodules in five, and urinary abnormalities in 10. Serological evidence of RA and SLE with positive RF and ANA and raised DNA antibodies was universal, all patients had haematological evidence of SLE, and all but one decreased serum complement levels. These cases suggest that the concurrence of RA and SLE is not as rare as previously considered and may occur more often than expected by chance alone.

PURPOSE: Providers have cited fear of taking away hope from patients as one of the principal reasons for deferring advance care planning (ACP). However, research is lacking on the relationship between ACP and hope. We sought to investigate the potential association between ACP and hope in advanced cancer. METHODS: This is a cross-sectional analysis of baseline data from a primary palliative care intervention trial. All patients had advanced solid cancers. Three domains of ACP were measured using validated questions to assess discussion with oncologists about end-of-life (EOL) planning, selection of a surrogate decision maker, and completion of an advance directive. Hope was measured using the Hearth Hope Index (HHI). Multivariable regression was performed, adjusting for variables associated with hope or ACP. RESULTS: A total of 672 patients were included in this analysis. The mean age was 69.3 ± 10.2 years; 54% were female, and 94% were White. Twenty percent of patients (132 of 661) reported having a discussion about EOL planning, 51% (342 of 668) reported completing an advance directive, and 85% (565 of 666) had chosen a surrogate. There was no difference in hope between patients who had and had not had an EOL discussion (adjusted mean difference in HHI, 0.55; P = .181 for adjusted regression), chosen a surrogate (adjusted HHI difference, 0.31; P = .512), or completed an advance directive (adjusted HHI difference, 0.11; P = .752). CONCLUSION: In this study, hope was equivalent among patients who had or had not completed 3 important domains of ACP. These findings do not support concerns that ACP is associated with decreased hope for patients with advanced cancer.
