Background and aims Patient-reported outcome measures are increasingly important in healthcare. European guidelines have recommended inclusion of patient feedback to capture adverse events due to colonoscopy, but this is rarely implemented. Methods The Norwegian Quality Assurance network for endoscopy (Gastronet) collects patient-reported outcome for colonoscopies. Free-text comments on patient reports from January to December 2015 were characterized as positive or negative. All negative free-text comments were scrutinized for information that might suggest colonoscopy-related adverse events...

BACKGROUND: Bowel length is an important factor in the management of patients with intestinal failure and short bowel syndrome (SBS). However, it is difficult to accurately measure the length of the small intestine. Our purpose was to demonstrate the feasibility of a dedicated software algorithm for calculating small intestine length based on magnetic resonance enterography (MRE) images. STUDY DESIGN: A custom algorithm for image thresholding, wall-identification, segmentation, and path extraction was designed and implemented...

Ultrafast charge recombination in hematite (α-Fe2O3) severely limits its applications in solar energy conversion and utilization, for instance, in photo-electrochemical water splitting. We report the first time-domain ab initio study of charge relaxation dynamics in α-Fe2O3 with and without the oxygen vacancy (Ov) defect, using non-adiabatic molecular dynamics implemented within time-dependent density functional theory. The simulations show that the hole trapping is the rate-limiting step in the electron-hole recombination process for both neutral and ionized Ov systems...

OBJECTIVE: Profoundly increased mortality rates in schizophrenia, largely caused by a higher risk and earlier onset of cardiovascular disease, remain a major challenge. During the human lifespan, advanced glycation end products (AGEs) accumulate, and their concentration is strongly linked to cardiovascular mortality. AGE accumulation can be accelerated by several pathways, including oxidative stress. METHODS: From March 2015 through January 2016, a case-control study including 111 patients with a recent-onset psychosis, 135 controls from a validation cohort, and 286 healthy controls was performed...

Adherence to medications is an important indicator of the quality of medication management and impacts on health outcomes and cost-effectiveness of healthcare delivery. Electronic healthcare data (EHD) are increasingly used to estimate adherence in research and clinical practice, yet standardization and transparency of data processing are still a concern. Comprehensive and flexible open-source algorithms can facilitate the development of high-quality, consistent, and reproducible evidence in this field. Some EHD-based clinical decision support systems (CDSS) include visualization of medication histories, but this is rarely integrated in adherence analyses and not easily accessible for data exploration or implementation in new clinical settings...

Despite massive global conservation strategies, tiger populations continued to decline until recently, mainly due to habitat loss, human-animal conflicts, and poaching. These factors are known to affect the genetic characteristics of tiger populations and decrease local effective population sizes. The Terai Arc Landscape (TAL) at the foothills of the Himalaya is one of the 42 source sites of tigers around the globe. Therefore, information on how landscape features and anthropogenic factors affect the fine-scale spatial genetic structure and variation of tigers in TAL is needed to develop proper management strategies for achieving long-term conservation goals...

Intercellular interactions play a central role at the tissue and whole organism level modulating key cellular functions in normal and disease states. Studies of cell-cell communications are challenging due to ensemble averaging effects brought about by intrinsic heterogeneity in cellular function which requires such studies to be conducted with small populations of cells. Most of the current methods for producing and studying such small cell populations are complex to implement and require skilled personnel limiting their widespread utility in biomedical research labs...

Roadway elevation data is critical for a variety of transportation analyses. However, it has been challenging to obtain such data and most roadway GIS databases do not have them. This paper intends to address this need by proposing a method to extract roadway elevation data from Google Earth (GE) for transportation applications. A comprehensive accuracy assessment of the GE-extracted elevation data is conducted for the area of conterminous USA. The GE elevation data was compared with the ground truth data from nationwide GPS benchmarks and roadway monuments from six states in the conterminous USA...

Depression and anxiety are highly prevalent disorders with an impact on existential aspects of person's life, including employment i.e., work performance (WP). In order to develop appropriate strategies, it is essential to identify determinants of WP. The objective of this study was to identify the built, social, attitudinal and health system-related environmental determinants of WP in workers with anxiety or depression in total (N = 1211) and regarding the level of disability. Hierarchical binary logistic regression was performed on data obtained from implementation of the WHO Model Disability Survey (MDS) in Chile in 2015...

A platform architecture for positioning systems is essential for the realization of a flexible localization system, which interacts with other systems and supports various positioning technologies and algorithms. The decentralized processing of a position enables pushing the application-level knowledge into a mobile station and avoids the communication with a central unit such as a server or a base station. In addition, the calculation of the position on low-cost and resource-constrained devices presents a challenge due to the limited computing, storage capacity, as well as power supply...

Since its popularization in the 1980s, evidence-based medicine has become the cornerstone of American health care. Many specialties rapidly adapted to the paradigm shift of health care by delivering treatment using the evidence-based guidelines. However, the field of plastic surgery has been slow to implement evidence-based medicine compared with the other specialties because of the challenges of performing randomized controlled trials, such as funding, variability in surgical skills, and difficulty with standardization of techniques...

RATIONALE: Bleeding esophageal and gastric varices constitute a serious complication in liver cirrhosis. Previous studies have shown that endoscopic ultrasonography (EUS) can be used to predict early esophageal variceal bleeding in liver cirrhosis. PATIENT CONCERNS: We report a case of a 46-year-old man with hepatitis B liver cirrhosis (CTP score, 5; Child-Pugh class, A) who was admitted to our hospital due to a decreased appetite lasting 1 week. DIAGNOSIS: He was initially diagnosed with decompensated hepatitis B cirrhosis; an abdominal computed tomography (CT) scan indicated a diagnosis of liver cirrhosis and portal hypertension (PHT)...

Thiopurines [e.g. mercaptopurine (MP)] are widely used as chemotherapeutic agents in the treatment of pediatric acute lymphoblastic leukemia with dose-limiting hematopoietic toxicity. Recently, germline variants in NUDT15 have been identified as a major genetic cause for MP-related bone marrow suppression, and there is increasing interest in the clinical implementation of NUDT15 genotype-guided MP dose individualization. Therefore, we sought to evaluate the effects of NUDT15 on thiopurine metabolism and identify pharmacologic markers to inform NUDT15 genotype-guided MP dosing...

The parallel microfluidic cytometer (PMC) is an imaging flow cytometer that operates on statistical analysis of low-pixel-count, one-dimensional (1D) line scans. It is highly efficient in data collection and operates on suspension cells. In this article, we present a supervised automated pipeline for the PMC that minimizes operator intervention by incorporating multivariate logistic regression for data scoring. We test the self-tuning statistical algorithms in a human primary T-cell activation assay in flow using nuclear factor of activated T cells (NFAT) translocation as a readout and readily achieve an average Z' of 0...
