The United States is simultaneously moving toward value-based payments for populations and precision medicine for individuals. During this evolution, innovations in payment and delivery that enhance tailoring of treatments to individuals while improving the value of care are needed. We propose one such innovation that would allow physician payment and patient cost sharing to better reflect the value of care by allowing the appropriateness of a service for a given patient in a given clinical situation to play a more meaningful role in the design of such incentives...

The pharmacological activity of active ingredients from Chinese medicine depends greatly on the microecological environment of probiotics in the human body. After effective ingredients from traditional Chinese medicines are metabolized or biotransformed by probiotics, their metabolites can increase pharmacological activity, and can be absorbed more easily to improve the bioavailability. Therefore, the combination of Chinese medicines with probiotics is the innovation point in R&D of functional food and Chinese medicines, and also a new thinking for the modernization of Chinese medicine...

Primary spontaneous pneumothorax has been defined as the disease of the 'young and healthy'. There are multiple possible therapies and in recent years, surgery has evolved towards the use of the uniportal thoracoscopic approach. The objective of our study is to describe and present an innovative approach to access to the thoracic cavity in patients with spontaneous pneumothorax. The surgery was performed using a single access of 20 mm at the level of the 8th intercostal space. For the isolation and suspension of any dystrophic area, we use a 'loop' of non-absorbable braided suture inserted through the IV intercostal space and successive wedge resection using an endoscopic 10 mm mechanical stapler...

Resting state networks (RSNs) in the human brain were recently detected using high-density electroencephalography (hdEEG). This was done by using an advanced analysis workflow to estimate neural signals in the cortex and to assess functional connectivity (FC) between distant cortical regions. FC analyses were conducted either using temporal (tICA) or spatial independent component analysis (sICA). Notably, EEG-RSNs obtained with sICA were very similar to RSNs retrieved with sICA from functional magnetic resonance imaging data...

Cancer-initiating cells (CICs) have been implicated in tumor development and aggressiveness. In ovarian carcinoma (OC), CICs drive tumor formation, dissemination, and recurrence, as well as drug resistance, thus accounting for the high death-to-incidence ratio of this neoplasm. However, the molecular mechanisms that underlie such a pathogenic role of ovarian CICs (OCICs) remain elusive. Here, we have capitalized on primary cells either from OC or from its tissues of origin to obtain the transcriptomic profile associated with OCICs...

The existence of pathogenic bacteria in drinking water has been a threat to the safety of human well-being. Traditional methods to detect bacteria are standard plate counts or rapid methods such as ELISA and PCR. However, those methods can be time-consuming or require pre-enrichment when detecting low concentrations of bacteria. Filter membrane has been used for bacteria collection and culturing when monitoring environmental water samples. In this study, we applied surface enhanced Raman spectroscopy (SERS) to rapidly screen bacteria cells on a filter membrane based on the unique signal from an indicator molecule, 4-mercaptophenylboronic acid (4-mpba), that can specifically bind to the surface of bacteria through diol group in its structure and give off consistent SERS signal...

Agricultural practices require novel products that allow sustainable development and commercial production according to the needs of farmers and consumers. Therefore, in the last decade, eco-friendly alternatives have been studied, so volatile organic compounds (VOCs) emitted by microorganisms have emerged as a cheaper, effective, efficient, and an eco-friendly alternative. VOCs are lipophilic compounds derived from microbial metabolic pathways with low molecular weight (<300 g mol-1 ), low boiling point, and high vapor pressure that allow them to act as signal molecules over short and long distances...

Due to considerable application of perfluorooctanoic acid (PFOA) and its refractory degradation, the widespread distribution of PFOA has already resulted in its' risks to environment and organisms. However, the intrinsic characteristic of pristine multi-walled carbon nanotubes (MWCNTs) limited their application for removing PFOA from aqueous medium. Therefore, three nano-metals (nano-crystalline iron, copper and zinc) grafted MWCNTs were synthesized and characterized by BET-N2 , TEM, FTIR, XPS and XRD as well as MWCNTs (as the control treatment) in this study...

INTRODUCTION: The nature of community pharmacy is changing, shifting from the preparation and distribution of medicines to the provision of cognitive pharmaceutical services (CPS); however, often the provision of traditional services leaves little time for innovative services. This study investigated the time community pharmacists spend on the tasks and activities of daily practice and to what extent they are able to implement CPS-related services in daily practice. METHODS: Self-reporting work sampling was used to register the activities of community pharmacists...

Hemostasis is a complex physiological mechanism that functions to maintain vascular integrity under any conditions. Its primary components are blood platelets and a coagulation network that interact to form the hemostatic plug, a combination of cell aggregate and gelatinous fibrin clot that stops bleeding upon vascular injury. Disorders of hemostasis result in bleeding or thrombosis, and are the major immediate cause of mortality and morbidity in the world. Regulation of hemostasis and thrombosis is immensely complex, as it depends on blood cell adhesion and mechanics, hydrodynamics and mass transport of various species, huge signal transduction networks in platelets, as well as spatiotemporal regulation of the blood coagulation network...
