Gut Microbiota Signatures with Potential Clinical Usefulness in Colorectal and Non-Small Cell Lung Cancers.

The application of bacterial metagenomic analysis as a biomarker for cancer detection is emerging. Our aim was to discover gut microbiota signatures with potential utility in the diagnosis of colorectal cancer (CRC) and non-small cell lung cancer (NSCLC). A prospective study was performed on a total of 77 fecal samples from CRC and NSCLC patients and controls. DNA from stool was analyzed for bacterial genomic sequencing using the Ion Torrent™ technology. Bioinformatic analysis was performed using the QIIME2 pipeline. We applied logistic regression to adjust for differences attributable to sex, age, and body mass index, and the diagnostic accuracy of our gut signatures was compared with other previously published results. The feces of patients affected by different tumor types, such as CRC and NSCLC, showed a differential intestinal microbiota profile. After adjusting for confounders, Parvimonas (OR = 53.3), Gemella (OR = 6.01), Eisenbergiella (OR = 5.35), Peptostreptococcus (OR = 9.42), Lactobacillus (OR = 6.72), Salmonella (OR = 5.44), and Fusobacterium (OR = 78.9) remained significantly associated with the risk of CRC. Two genera from the Ruminococcaceae family, DTU089 (OR = 20.1) and an uncharacterized genus (OR = 160.1), were associated with the risk of NSCLC. Our two panels had better diagnostic capacity for CRC (AUC = 0.840) and NSLC (AUC = 0.747) compared to the application of two other published panels to our population. Thus, we propose a gut bacteria panel for each cancer type and show its potential application in cancer diagnosis.

Role of Telomere Length in Survival of Patients with Idiopathic Pulmonary Fibrosis and Other Interstitial Lung Diseases.

Interstitial lung diseases (ILDs) constitute a group of more than 200 disorders, with idiopathic pulmonary fibrosis (IPF) being one of the most frequent. Telomere length (TL) shortening causes loss of function of the lung parenchyma. However, little is known about its role as a prognostic factor in ILD patients. With the aim of investigating the role of TL and telomerase activity in the prognosis of patients affected by ILDs, we analysed lung tissue samples from 61 patients. We measured relative TL and telomerase activity by conventional procedures. Both clinical and molecular parameters were associated with overall survival by the Kaplan-Meier method. Patients with IPF had poorer prognosis than patients with other ILDs (p = 0.034). When patients were classified according to TL, those with shortened telomeres reported lower overall survival (p = 0.085); differences reached statistical significance after excluding ILD patients who developed cancer (p = 0.021). In a Cox regression analysis, TL behaved as a risk-modifying variable for death associated with rheumatic disease (RD) co-occurrence (p = 0.029). Also, in patients without cancer, ferritin was significantly increased in cases with RD and IPF co-occurrence (p = 0.032). In relation to telomerase activity, no significant differences were detected. In conclusion, TL in lung tissue emerges as a prognostic factor in ILD patients. Specifically, in cases with RD and IPF co-occurrence, TL can be considered as a risk-modifying variable for death.

The Use of Fissios App© as a Complement to a Face-to-Face Respiratory Physiotherapy Program versus an Attendance-Only Face-to-Face Physiotherapy Program in Patients Scheduled for Thoracic Surgical Procedures Reduces the Risk of Developing Postoperative Pulmonary Complications-A Quasi-Experimental Study.

Postoperative pulmonary complications (PPCs) increase the hospital length of stay (LOS) and the cost of healthcare associated with surgical procedures. Strategies to reduce PPCs begin before surgery and continue in the postoperative period. Fissios App© is a smartphone application that contains perioperative medical advice and a structured respiratory physiotherapy program. The objective was to implement the use of this app in a group of patients scheduled for a thoracic surgical procedure and determine its efficacy in reducing PPCs. This was a quasi-experimental study in which all patients attended a face-to-face respiratory physiotherapy program, and the intervention group used Fissios App© as a complement. We prospectively recorded the postoperative evolution of both groups, analyzed the categorical differences and quantitative variables, and created a binary logistic regression model. We recruited 393 patients (131 intervention and 262 control). The intervention group had a lower incidence of PPCs (12.2% versus 24% in the control group, p = 0.006), a shorter LOS (a median of 3 days (IQR = 2-5) versus 4 days (IQR = 3-6, p = 0.001) in the control group), and a reduction in the risk of developing PPCs by 63.5% (OR: 0.365, 95% CI: 0.17-0.78). The use of Fissios App© improved the clinical outcomes after surgery and reduced the probability of developing PPCs.

Preoperative detection and evaluation of the need for psychological intervention in cancer and non-cancer patients referred to thoracic surgery.

OBJECTIVES: (a) to evaluate and compare the psychological treatment needs of patients with cancer and non-cancer, who are going to undergo scheduled thoracic surgery, and (b) evaluate and compare the diagnostic accuracy of the screening tests of psychological treatment needs for cancer and non-cancer patients. METHOD: The need for psychological treatment was evaluated in a total of 169 patients prior to thoracic surgery, through a clinical interview. The screening tests used were: the physician's judgment (yes/no), the Hospital Anxiety and Depression Scale (HADS) and, the single-item interview to assess depression "Do you feel depressed?" (DEPQ). RESULTS: The number of patients who needed psychological treatment in the total sample was 47 (27.81%), in non-cancer-patients: 22 (30.99%) and in cancer patients: 25 (25.51%). The participants with treatment needs were more often young women with primary education levels, with more fears and concerns regarding their disease. With respect to the screening tests, the HADS-T (cut-off point ≥13) obtained a sensitivity (SE) of 0.75 and Specificity (SP) of 0.81 in the total sample. In patients with cancer, the HADS total score (cut-off point ≥10) obtained an SE=0.84 and SP=0.80, and, in non-cancer patients, the HADS total score (cut-off point ≥13) showed an SE=0.59 and SP=0.84. The DEPQ and the physician's judgment did not achieve adequate levels of precision. CONCLUSIONS: A high percentage of patients have psychological treatment needs before performing thoracic surgery, which are similar for cancer and non-cancer patients. Preoperative detection of patients who need psychological intervention is feasible with a simple screening test: HADS, which achieves greater precision in cancer patients.

Programmed Cell-Death Mechanism Analysis Using Same-Cell, Multimode DNA and Proteoform Electrophoresis.

Gaining insight into the timing of cell apoptosis events requires single-cell-resolution measurements of cell viability. We explore the supposition that mechanism-based scrutiny of programmed cell death would benefit from same-cell analysis of both the DNA state (intact vs fragmented) and the protein states, specifically the full-length vs cleaved state of the DNA-repair protein PARP1, which is cleaved by caspase-3 during caspase-dependent apoptosis. To make this same-cell, multimode measurement, we introduce the single-cell electrophoresis-based viability and protein (SEVAP) assay. Using SEVAP, we (1) isolate human breast cancer SKBR3 cells in microwells molded in thin polyacrylamide gels, (2) electrophoretically separate protein molecular states and DNA molecular states-using differences in electrophoretic mobility-from each single-cell lysate, and (3) perform in-gel DNA staining and PARP1 immunoprobing. Performed in an open microfluidic device, SEVAP scrutinized hundreds to thousands of individual SKBR3 cells. In each single-cell lysate separation, SEVAP baseline-resolved fragmented DNA from intact DNA (R s = 5.17) as well as cleaved PARP1 from full-length PARP1 (R s = 0.66). Comparing apoptotic and viable cells showed statistically similar profiles (expression, mobility, peak width) of housekeeping protein ß-tubulin (Mann-Whitney U test). Clustering and cross-correlation analysis of DNA migration and PARP1 migration identified nonapoptotic vs apoptotic cells. Clustering analysis further suggested that cleaved PARP1 is a suitable apoptosis marker for this system. SEVAP is an efficient, multimode, end-point assay designed to elucidate cell-to-cell heterogeneity in mechanism-specific signaling during programmed cell death.

Physicians' viewpoints on faculty anatomists and dissection of human bodies in the undergraduate medical studies.

BACKGROUND: Studies abound regarding the views of faculty anatomists and medical students on the importance of anatomy and the dissection of human bodies, but very little is known about the views of practicing physicians. METHODS: A survey was distributed among physicians and surgeons practicing in Spain in order to find out their views on the practice and consequences of human dissection by undergraduate students of medicine. The most relevant definition to qualify faculty anatomists of medical schools was also requested. Responses were repeatedly clustered into characteristic subgroups for analysis. RESULTS: In total, 536 physicians and surgeons belonging to 36 different specialties in seven Spanish hospitals responded to the survey. The results highlighted two main facts. Firstly, faculty anatomists were perceived as teachers, above any other professional identity (namely: physician, biologist or scientist); nonetheless, the ascription of identities varied between specialties (p=0.009); and it also depended on whether the respondents had dissected in their undergraduate degree (p=0.03) and on the respondent's gender (p=0.03). Secondly, physicians and surgeons confirmed that dissecting human cadavers serves the undergraduate student not only for acquiring anatomical knowledge, but also essential skills and attitudes, including professionalism. CONCLUSIONS: The results strongly suggest that dissection practice should be reinforced and enriched in undergraduate medical school. As this is important in itself, the results of the study could also help with the development of strategies to alleviate the current shortage of adequately trained anatomists for medical degrees.

Multimodal detection of protein isoforms and nucleic acids from low starting cell numbers.

Protein isoforms play a key role in disease progression and arise from mechanisms involving multiple molecular subtypes, including DNA, mRNA and protein. Recently introduced multimodal assays successfully link genomes and transcriptomes to protein expression landscapes. However, the specificity of the protein measurement relies on antibodies alone, leading to major challenges when measuring different isoforms of the same protein. Here we utilize microfluidic design to perform same-cell profiling of DNA, mRNA and protein isoforms (triBlot) on low starting cell numbers (1-100 s of cells). After fractionation lysis, cytoplasmic proteins are resolved by molecular mass during polyacrylamide gel electrophoresis (PAGE), adding a degree of specificity to the protein measurement, while nuclei are excised from the device in sections termed "gel pallets" for subsequent off-chip nucleic acid analysis. By assaying TurboGFP-transduced glioblastoma cells, we observe a strong correlation between protein expression prior to lysis and immunoprobed protein. We measure both mRNA and DNA from retrieved nuclei, and find that mRNA levels correlate with protein abundance in TurboGFP-expressing cells. Furthermore, we detect the presence of TurboGFP isoforms differing by an estimated <1 kDa in molecular mass, demonstrating the ability to discern different proteoforms with the same antibody probe. By directly relating nucleic acid modifications to protein isoform expression in 1-100 s of cells, the triBlot assay holds potential as a screening tool for novel biomarkers in diseases driven by protein isoform expression.
