BACKGROUND: Chronic kidney disease (CKD) patients who live far (>30 miles) from their nephrologist experience lower rates of clinic visit adherence, limited access to treatment, and higher rates of hospitalization and mortality than patients who live in close proximity to their nephrologist. Strategies to minimize disparities between urban and remotely located CKD patients are needed. The purpose of this study was to determine whether adherence to clinic visits and clinical outcomes in the remote management of CKD via telenephrology is comparable to in-person conventional care...

LC-MS/MS has been the dominant analytical technology for quantitative bioanalysis of drugs and metabolites for more than two decades. Despite this, a very fundamental question like how much separation is required for LC-MS/MS quantitative bioanalysis of drugs and metabolites has not been adequately addressed. Some think that no or only very limited separation is necessary thanks to the unparalleled selectivity offered by tandem mass spectrometry. Others think that the more separation, the better, because of the potential detrimental impact of matrix effect (ion suppression or enhancement)...

The demand to outperform current technologies pushes scientists to develop novel strategies to enable fabricating materials with exceptional properties. Along this line, lightweight structural materials are of great interest due to their versatile applicability as sensors, catalysts, battery electrodes and acoustic or mechanical dampers. Here we report a strategy to design ultralight (ρ = 3 mg/cm3) and hierarchically structured ceramic scaffolds of macroscopic size. Such scaffolds exhibit mechanical reversibility comparable to that of microscopic metamaterials, leading to a macroscopically remarkable dynamic mechanical performance...

Timing points used in running races and other competition events are generally based on radio-frequency identification (RFID) technology. Athletes' times are calculated via passive RFID tags and reader kits. Specifically, the reader infrastructure needed is complex and requires the deployment of a mat or ramps which hide the receiver antennae under them. Moreover, with the employed tags, it is not possible to transmit additional and dynamic information such as pulse or oximetry monitoring, alarms, etc. In this paper we present a system based on two low complex schemes allowed in Bluetooth Low Energy (BLE): the non-connectable undirected advertisement process and a modified version of scannable undirected advertisement process using the new capabilities present in Bluetooth 5...

Three-dimensional (3D) bio-printing is a revolutionary technology to reproduce a 3D functional living tissue scaffold in-vitro through controlled layer-by-layer deposition of biomaterials along with high precision positioning of cells. Due to its bio-compatibility, natural hydrogels are commonly considered as the scaffold material. However, the mechanical integrity of a hydrogel material, especially in 3D scaffold architecture, is an issue. In this research, a novel hybrid hydrogel, that is, sodium alginate with carboxymethyl cellulose (CMC) is developed and systematic quantitative characterization tests are conducted to validate its printability, shape fidelity and cell viability...

Patient engagement in health care decisions largely depends on a patient's health literacy and the health literacy attributes of the health care organization. Librarians have an established role in connecting patients with health information in the context of their care. However, librarians can play a larger role in helping to make changes in their organization's health literacy attributes. This article discusses one medical library's process of leading systematic assessment of their organization's health literacy attributes...

Farmers and farm workers have been recognised as a group at high risk of suicide in Australia. This study aims to identify and better understand environmental factors associated with suicide among Australian farmers and farm workers. Qualitative analysis was undertaken in accordance with the Consolidated Criteria for Reporting Qualitative Research. Male and female focus groups were conducted separately with people who lived or worked on a farm in six farming communities. Qualitative analyses showed that a number of environmental influences may contribute to the increased risk of suicide: extreme climatic events; isolation; service availability; access to, and frequent use of firearms; death and suffering of animals; government and legislation; technology; and property values...

BACKGROUND: Botulinum toxin type A (BoNT-A) injections is the accepted first-line therapy for cervical dystonia (CD), however, numerous patients discontinue treatment early due to perceived sub-optimal relief. To improve BoNT-A therapy for CD, proper assessment of neck motion and selection of relevant muscles and dosing must be met. Kinematic technology may improve treatment outcomes by guiding physicians to better tailor muscle selection and BoNT-A dosing for CD therapy. METHODS: 28 CD participants were placed into either group: expert injector determined injection patterns by visual assessment ("vb") versus injection patterns based on kinematics interpreted by an expert injector ("kb")...
