This work justifies that fingertip is an ideal platform for pulse signals monitoring, which would be a competitive alternative to existing complex health monitoring systems.<br /><br /> Current methods to identify, classify, and predict tumor behavior mostly rely on histology, immunohistochemistry, and molecular determinants. However, better predictive markers are required for tumor diagnosis and evaluation. Due, in part, to recent technological advancements, metabolomics and lipid biomarkers have become a promising area in cancer research. Therefore, there is a necessity for novel and complementary techniques to identify and visualize these molecular markers within tumors and surrounding tissue.<br /><br /> Since its introduction, mass spectrometry imaging (MSI) has proven to be a powerful tool for mapping analytes in biological tissues. By adding the label-free specificity of mass spectrometry to the detailed spatial information of traditional histology, hundreds of lipids can be imaged simultaneously within a tumor. MSI provides highly detailed lipid maps for comparing intra-tumor, tumor margin, and healthy regions to identify biomarkers, patterns of disease, and potential therapeutic targets. In this manuscript, recent advancement in sample preparation and MSI technologies are discussed with special emphasis on cancer lipid research to identify tumor biomarkers.<br /><br /> MSI offers a unique approach for biomolecular characterization of tumor tissues and provides valuable complementary information to histology for lipid biomarker discovery and tumor classification in clinical and research cancer applications.<br /><br />MSI offers a unique approach for biomolecular characterization of tumor tissues and provides valuable complementary information to histology for lipid biomarker discovery and tumor classification in clinical and research cancer applications.<br /><br /> The status of targeted genes and the association between targeted genes and clinicopathological features in Chinese lung cancer patients remains to be elucidated.<br /><br /> The status of 10 targeted genes was evaluated by next-generation sequencing (NGS) in 884 non-small cell lung cancer (NSCLC) patients. The relationship between gene alterations and clinicopathological characters was analyzed.<br /><br /> Overall, 684 (77.4%) patients harbored gene alterations, and EGFR (510, 57.7%) was found to be the most common type of mutation followed by KRAS (91, 10.3%), HER2 (38, 4.3%), PIK3CA (32, 3.6%), ALK (21, 2.4%), BRAF (10, 1.1%), ROS1 (5, 0.6%), RET (5, 0.6%), MET (4, 0.5%) and NRAS (1, 0.1%). Gene alterations were more frequent in females, non-smokers and adenocarcinoma (P &lt; 0.001). EGFR mutations were associated with women, non-smokers, normal level of serum tumor markers, and adenocarcinoma (P &lt; 0.001). Patients without lymph node metastasis (P = 0.012), or early stage disease (P &lt; 0.001) exhibited a higher EGFR meir association with clinicopathological parameters of Chinese non-small cell lung cancer (NSCLC) patients in eastern China.<br /><br /> Some rare synchronous mutations were detected in our study by next-generation sequencing (NGS).<br /><br />Some rare synchronous mutations were detected in our study by next-generation sequencing (NGS).<br /><br /> To determine differences in frequencies of vaccine-preventable diseases between alcoholic liver disease (ALD) and non-alcoholic liver disease (NALD) patients.<br /><br /> This population-based cohort study used USA national inpatient sample ICD-9 codes from January 2012 to September 2015. Frequencies of admissions for ALD and NALD in patients with pneumococcal pneumonia, influenza, herpes zoster virus, varicella zoster virus, hepatitis A, hepatitis B, human papilloma virus, meningococcal meningitis, diphtheria, pertussis and tetanus were measured. Frequencies and patients' characteristics were compared for ALD and NALD using χ<br /><br /> test and multivariate logistic regression analysis.<br /><br /> There was no difference in admissions for hepatitis A and pneumococcal pneumonia between the ALD and NALD groups. There were fewer admissions for hepatitis B (1.17% vs 1.80%, odds ratio [OR] 0.64, P &lt; 0.01), herpes zoster (0.12% vs 0.17%, OR 0.69, P &lt; 0.01), influenza (0.16% vs 0.26%, OR 0.59, P &lt; 0.01) and all others (0.005% vs 0.015%, OR 0.36, P = 0.01) in the ALD group than the NALD group. The extreme all patient refined-diagnosis related groups mortality risk was 15.24% in ALD and 7.77% in NALD admissions (P &lt; 0.0001).<br /><br /> The most frequent vaccine-preventable disease in both groups was hepatitis B. Patients with NALD had higher odds of admissions for hepatitis B, herpes zoster virus, influenza and other vaccine-preventable disease than ALD patients. However, the ALD group had a higher risk of mortality when admitted to hospital with a vaccine-preventable disease than the NALD group.<br /><br />The most frequent vaccine-preventable disease in both groups was hepatitis B.

Reduced muscle mass may be related to reduced respiratory muscle strength; however, the impact of this on lung functional parameters is not characterized in adult allogeneic haematopoietic stem cell transplant (alloHCT) recipients.<br /><br /> A consecutive retrospective series (n=296) of patients who had alloHCT at a comprehensive cancer centre between March 2005 and April 2015 were included. Pre-transplant CT scans were used to quantify skeletal muscle and adipose tissue at the fourth thoracic (T4) and/or third lumbar (L3) level. Tumour and patient characteristics were recorded, including forced expiratory volume in 1second (FEV<br /><br /> ) by spirometry. Regression models were created to characterize predictive relationships.<br /><br /> A total of 296 patients (♂n=161; ♀n=135) were included, all of whom had chest CT as part of standard care; a subset of these (n=215, 72.6%) also had abdominal CT. Diagnoses were non-Hodgkins lymphoma (n=165), acute myeloid leukaemia (n=66), Hodgkin's disease (n=14), acute lymphocytic leukaemia (n=14), myelodysplastic syndromes (n=18), and other (n=19).
