RESULTS Of the 102 patients, 95 completed the present study. No significant improvement was seen in anxiety, depression, or health literacy at the end of treatment between the BPSS and no-BPSS app groups. Overall, 1868 side effects were reported. When the patients' records were compared with the medical staff records, the analysis revealed that the medical staff had underestimated some grade 3 symptoms. CONCLUSION The BPSS app is a feasible tool for patients with breast cancer and might be useful as a support tool for information sharing between patients and medical staff in an effort to optimize chemotherapy and deliver suitable patient care and support. BACKGROUND Cells detaching from the primary tumor site are metastasis initiator cells, and the detection of CTC, known as liquid biopsy, is an important test of biomarkers of cancer progression. We investigated the molecular characterization of circulating tumor cells (CTCs), profiled the plasma microRNA (miR) content, and analyzed the relationship with the clinical outcomes by sampling the peripheral blood from patients with locally advanced breast cancer before and after neoadjuvant chemotherapy. PATIENTS AND METHODS Markers of breast cancer, epithelial-mesenchymal transition (EMT), drug resistance, and stem cells were used for CTC isolation and characterization. Plasma miR profiles were obtained from selected patients with CTC positivity determined using next-generation sequencing. RESULTS The proportion of CTC, EMT, and stem cell marker positivity was 16.7%, 8.3%, and 25% before and 18.2%, 15.2%, and 9.1% after treatment, respectively. A significant correlation was found between the pretreatment CTCs and ALDH1 positivity (P = .0245). These CTCs with stemness properties were observed in most hormone receptor-positive, human epidermal growth factor receptor 2-negative cases and were also present with a high incidence in cases of early metastasis. miR-146b-5p and miR-199a-5p, which are involved in metastasis, invasion, and EMT, were accompanied by CTC positivity, and miR-4646-3p was associated with the development of early metastasis. CONCLUSIONS Molecular characterization of CTCs and miR profiling of serial samples from patients with locally advanced breast cancer during neoadjuvant chemotherapy appears to be a very useful in predicting cure and clinical course and might be a key to developing new targeted therapies. BACKGROUND The neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) have been associated with the prognosis in breast cancer (BC). The relationship of the NLR and PLR with chemotherapy sensitivity and prognosis in luminal B-like (human epidermal growth factor receptor 2-negative [HER2-]) BC are not well studied. PATIENTS AND METHODS The clinical data from 980 patients with luminal B-like (HER2-) BC from June 2012 to June 2016 were collected. The differences among the variables were calculated using the χ2 test. The associations among the clinicopathologic factors, pretreatment NLR, pretreatment PLR, and disease-free survival (DFS) were analyzed using Kaplan-Meier curves and Cox analyses. RESULTS The median follow-up was 37 months (range, 5-77 months). For the 480 patients who had received neoadjuvant chemotherapy, low pretreatment PLR values were associated with higher pathologic complete response (pCR) rates compared with the high PLR group (15.8% for low vs. 9.2% for high PLR group; P = .027). Multivariate analyses showed that larger tumors, a greater number of lymph nodes involved, a high Ki-67 score, and a high PLR were independent prognostic factors of worse outcomes for the patients with luminal B-like (HER2-) BC. The risk of metastasis and/or recurrence was greater for the high PLR group than for the low PLR group (hazard ratio, 1.576; 95% confidence interval, 1.039-2.390; P = .032). The pretreatment NLR showed no such associations among this cohort of patients. CONCLUSIONS The results of the present study have shown that the pretreatment PLR is superior to the NLR as a predictor of pCR and DFS outcomes in patients with luminal B-like (HER2-) BC. A low pretreatment PLR was associated with higher pCR rates after neoadjuvant chemotherapy and was an independent predictive factor for better DFS outcomes among patients with luminal B-like (HER2-) BC. BACKGROUND N-chlorotaurine (NCT) is an endogenous active chlorine compound that can be used as an antiseptic and anti-infective in different body regions. Recently, tolerability of inhaled NCT has been demonstrated in humans so that it is of interest for future treatment of cystic fibrosis. In the present study, we tested the bactericidal and fungicidal activity of NCT in different lung cell culture models. METHODS Bacteria (Staphylococcus aureus, Pseudomonas aeruginosa) and fungi (Candida albicans, Exophiala dermatitidis) were co-incubated with lung epithelial cell cultures, and after 4 h NCT was added. After different incubation times, aliquots were removed and quantitative cultures were performed. RESULTS NCT at the therapeutically applied concentration of 1% (55 mM) completely killed the test pathogens within 15 - 30 min at 20 °C and at 37 °C. Killing by 0.3% NCT lasted up to 4 h dependent on the pathogen at 20 °C and up to 1 h at 37 °C. 0.1% NCT was the threshold concentration for killing since this amount of oxidation capacity was consumed by reactions with the organic compounds of the medium within 3 h (20 °C) and 0.5 h (37 °C). CONCLUSIONS NCT in therapeutic concentration demonstrated its microbicidal activity in the presence of lung epithelial cells. Remarkably, particularly the fungicidal activity was higher under these conditions than in phosphate buffer. This can be explained by formation of the stronger microbicidal monochloramine in equilibrium by transchlorination. The results suggest the suitability of NCT as inhalation medication in the lung. OBJECTIVES To investigate the effects of 1-year lumacaftor-ivacaftor treatment on abnormalities in glucose tolerance (AGT) in Phe508del homozygous cystic fibrosis (CF) patients. METHODS Untreated CF patients with glucose intolerance or newly diagnosed diabetes were included in a prospective, observational study. After 1-year lumacaftor-ivacaftor treatment, AGT were evaluated by using oral glucose tolerance test. selleck chemicals llc RESULTS Forty patients participated. 78% of patients had glucose intolerance and 22% diabetes at baseline. After one-year treatment, 50% of patients had normal glucose tolerance, 40% glucose intolerance, and 10% diabetes (p less then 0.001). The two-hour OGTT glycemia decreased from 171 (153-197) to 139 (117-162) mg/dL (p less then 0.001). 57.5% (n = 23) of patients improved their glucose tolerance with a significant decrease in both 1-hour (p less then 0.01) and 2-hour (p less then 0.001) OGTT glycemia. CONCLUSION Improvements in AGT were observed following 1-year lumacaftor-ivacaftor treatment. Larger studies are needed to comprehensively assess CF transmembrane conductance regulator (CFTR) modulators.
