Aromatherapy is an integrative intervention that uses essential oils to address symptom management, potentially as a first-line intervention or as a complement to other medical treatments. Aromatherapy is gaining widespread acceptance and increased scientific evidence of efficacy. Integrative and holistic nursing care uses integrative therapies such as aromatherapy and the principle of moving from a less invasive intervention to a more invasive intervention according to patient needs, symptoms, and preferences. Aromatherapy is often provided as a minimally invasive, independent, and integrative nursing intervention. This article describes the process used to introduce essential oils into practices at a large Midwestern academic medical center.

Abstract BACKGROUND Current recommendations for screening for monoclonal gammopathies include serum protein electrophoresis (PEL), imunofixation electrophoresis (IFE), and free light chain (FLC) ratios to identify or rule out an M-protein. The aim of this study was to examine the feasibility of an assay based on immunoenrichment and MALDI-TOF-MS (MASS-SCREEN) to qualitatively screen for M-proteins. METHODS Serum from 556 patients previously screened for M-proteins by PEL and IFE were immunopurified using a κ/λ-specific nanobody bead mixture. Following purification, light chains (LC) were released from their heavy chains by reduction. MALDI-TOF analysis was performed and the mass-to-charge LC distributions were visually examined for the presence of an M-protein by both unblinded and blinded analysts. RESULTS In unblinded analysis, MASS-SCREEN detected 100% of the PEL-positive samples with an analytical sensitivity and specificity of 96% and 81% using IFE positivity as the standard. In a blinded analysis using 6 different laboratory personnel, consensus was reached in 92% of the samples. Overall analytical sensitivity and specificity were reduced to 92% and 80%, respectively. FLC ratios were found to be abnormal in 28% of MASS-SCREEN–negative samples, suggesting FLC measurements need to be considered in screening. CONCLUSIONS MASS-SCREEN could replace PEL in a panel that would include FLC measurements. Further studies and method development should be performed to validate the clinical sensitivity and specificity and to determine if this panel will suffice as a general screen for monoclonal proteins.

Purpose To provide guidance to clinicians regarding the use of neoadjuvant chemotherapy and interval cytoreduction among women with stage IIIC or IV epithelial ovarian cancer. Methods The Society of Gynecologic Oncology and the American Society of Clinical Oncology convened an Expert Panel and conducted a systematic review of the literature. Results Four phase III clinical trials form the primary evidence base for the recommendations. The published studies suggest that for selected women with stage IIIC or IV epithelial ovarian cancer, neoadjuvant chemotherapy and interval cytoreduction are noninferior to primary cytoreduction and adjuvant chemotherapy with respect to overall and progression-free survival and are associated with less perioperative morbidity and mortality. Recommendations All women with suspected stage IIIC or IV invasive epithelial ovarian cancer should be evaluated by a gynecologic oncologist prior to initiation of therapy. The primary clinical evaluation should include a CT of the abdomen and pelvis, and chest imaging (CT preferred). Women with a high perioperative risk profile or a low likelihood of achieving cytoreduction to < 1 cm of residual disease (ideally to no visible disease) should receive neoadjuvant chemotherapy. Women who are fit for primary cytoreductive surgery, and with potentially resectable disease, may receive either neoadjuvant chemotherapy or primary cytoreductive surgery. However, primary cytoreductive surgery is preferred if there is a high likelihood of achieving cytoreduction to < 1 cm (ideally to no visible disease) with acceptable morbidity. Before neoadjuvant chemotherapy is delivered, all patients should have confirmation of an invasive ovarian, fallopian tube, or peritoneal cancer.

The chronic lymphocytic leukemia International Prognostic Index (CLL‐IPI) combines 5 parameters (age, clinical stage, TP53 status [normal vs. del(17p) and/or TP53 mutation], IGHV mutational status, serum β2‐microglobulin) to predict survival and time‐to‐first‐treatment (TTFT) in CLL patients. We performed an observational study in 337 prospectively collected, Binet stage A patients to validate the ability of the CLL‐IPI to predict TTFT in an independent cohort of early stage CLL patients. The CLL‐IPI score stratified Binet stage A patients into three subgroups with different outcome. Since the CLL‐IPI was originally developed to predict survival, we next investigated the optimal cut‐off score to predict TTFT in Binet stage A patients. Recursive partitioning analysis identified three subsets with scores of 0 (n = 139), 1 (n = 90), and ≥ 2(n = 108). The probability of remaining free from therapy 5 years after diagnosis was 85%, 67% and 46% in these three categories (P < 0.0001.; C‐statistic:c = 0.72; 95% CI:0.58‐0.81). This optimized CLL‐IPI scoring for TTFT was subsequently validated in an independent cohort of Binet A patients from the Mayo Clinic (n = 525). The ability of either original or optimized CLL‐IPI to predict TTFT was equivalent to other prognostic models specifically designed for this endpoint (2011 MDACC score and O‐CLL1 score). Although originally developed to predict suvival, the CLL‐IPI is useful for predicting TTFT in early stage CLL patients. Am. J. Hematol. 91:1090–1095, 2016. © 2016 Wiley Periodicals, Inc.

Background Intracranial aneurysms ( IAs ), abdominal aortic aneurysms ( AAAs ), and thoracic aortic aneurysms ( TAAs ) all have a familial predisposition. Given that aneurysm types are known to co‐occur, we hypothesized that there may be shared genetic risk factors for IAs , AAAs, and TAAs . Methods and Results We performed a mega‐analysis of 1000 Genomes Project‐imputed genome‐wide association study ( GWAS ) data of 4 previously published aneurysm cohorts: 2 IA cohorts (in total 1516 cases, 4305 controls), 1 AAA cohort (818 cases, 3004 controls), and 1 TAA cohort (760 cases, 2212 controls), and observed associations of 4 known IA , AAA , and/or TAA risk loci (9p21, 18q11, 15q21, and 2q33) with consistent effect directions in all 4 cohorts. We calculated polygenic scores based on IA ‐, AAA ‐, and TAA ‐associated SNP s and tested these scores for association to case‐control status in the other aneurysm cohorts; this revealed no shared polygenic effects. Similarly, linkage disequilibrium–score regression analyses did not show significant correlations between any pair of aneurysm subtypes. Last, we evaluated the evidence for 14 previously published aneurysm risk single‐nucleotide polymorphisms through collaboration in extended aneurysm cohorts, with a total of 6548 cases and 16 843 controls ( IA ) and 4391 cases and 37 904 controls ( AAA ), and found nominally significant associations for IA risk locus 18q11 near RBBP 8 to AAA (odds ratio [ OR ]=1.11; P =4.1×10 −5 ) and for TAA risk locus 15q21 near FBN 1 to AAA ( OR =1.07; P =1.1×10 −3 ). Conclusions Although there was no evidence for polygenic overlap between IAs , AAAs , and TAAs , we found nominally significant effects of two established risk loci for IAs and TAAs in AAAs . These two loci will require further replication.

Abstract The Transforming Growth Factor-β (TGFβ)/SMAD signaling pathway can function as either a tumor suppressor or metastasis promoter during tumor progression. In normal epithelial cells and early stages of epithelial tumorigenesis TGFβ functions as a tumor suppressor to decrease cell proliferation or induce apoptosis. However, during malignant progression tumor cells no longer respond to the anti-proliferative effects of TGFβ, but instead undergo an epithelial-to-mesenchymal transition (EMT) whereby cells acquire a migratory and invasive phenotype which promotes tumor metastasis. Resolution of the dichotomy in TGFβ function and a further understanding of its tumor suppressor and metastasis promoting functions may uncover new strategies for the treatment of epithelial cancers. In previous studies we demonstrated an important role of the TGFβ-Inducible Early Gene-1 (TIEG1)/Krüppel-like Factor-10 (KLF10) as a central regulator of TGFβ/SMAD signaling and the anti-proliferative functions of TGFβ. In this study we examined the role of KLF10 in controlling the TGFβ-induced EMT in human lung adenocarcinoma cells. We show that depletion of KLF10 results in a more pronounced induction of EMT in human A549 lung adenocarcinoma cells as assessed by quantitative real-time PCR, changes in cellular morphology and immunofluorescence microscopy, and transcriptome-wide (RNA-seq) analyses. Moreover, chromatin immunoprecipitation (ChIP) and chromatin immunoprecipitation-sequencing (ChIP-seq) analysis shows that KLF10 directly binds to GC-rich sequences in the promoter region of the EMT-promoting transcription factor SLUG/SNAI2 to repress its transcription. Consistent with these findings, an analysis of KLF10 and SNAI2 expression in lung cancer revealed that while KLF10 levels are decreased in lung cancer vs. normal samples, SNAI2 levels are increased. Additional ChIP studies showed that KLF10 recruits HDAC1 to the SNAI2 promoter and is required for the removal of activating histone acetylation marks. These findings reveal a previously unknown function of KLF10 in suppressing TGFβ-induced EMT and represent a significant advancement in the understanding the molecular dichotomy of TGFβ function during tumor progression.
