Consideration of quality of life has developed into an important concept of a patient-oriented medicine in the last 50 years. With it, it should be possible to capture the subjective experience of the patients and describe its different dimensions. Today, the quality of life as a patient-reported endpoint is also an integral part of the early benefit assessment under the German Drug Market Reorganization Act. In the treatment of schizophrenic patients, however, improvement in quality of life as an accepted target criterion has only been established with delay...

Background: The prevalence of moderate or complex (moderate-complex) congenital heart defects (CHDs) among adults is increasing due to improved survival, but many patients experience lapses in specialty care or their CHDs are undocumented in the medical system. There is, to date, no efficient approach to identify this population. Objective: To develop and assess the performance of a risk score to identify adults aged 20-60 years with undocumented specific moderate-complex CHDs from electronic health records (EHR)...

The human cerebral cortex is highly folded into diverse gyri and sulci. Accumulating evidences suggest that gyri and sulci exhibit anatomical, morphological, and connectional differences. Inspired by these evidences, we performed a series of experiments to explore the frequency-specific differences between gyral and sulcal neural activities from resting-state and task-based functional magnetic resonance imaging (fMRI) data. Specifically, we designed a convolutional neural network (CNN) based classifier, which can differentiate gyral and sulcal fMRI signals with reasonable accuracies...

The Government of Canada and the Society of Obstetricians and Gynaecologists of Canada both recommend a daily multivitamin supplement containing 400 µg folic acid (FA) for the primary prevention of neural tube defects among low-risk women from before conception and throughout lactation. Prenatal supplements marketed and prescribed in Canada typically exceed the recommended dose, usually providing ≥1000 µg FA/d. This high daily dose, coupled with staple-food FA fortification, has resulted in the observation of very high blood folate concentrations among reproductive-aged women consuming FA-containing supplements...

BACKGROUND: DNA integrity and stability are critical determinants of cell viability. This is especially true in the female germline, wherein DNA integrity underpins successful conception, embryonic development, pregnancy and the production of healthy offspring. However, DNA is not inert; rather, it is subject to assault from various environment factors resulting in chemical modification and/or strand breakage. If structural alterations result and are left unrepaired, they have the potential to cause mutations and propagate disease...

Safety-relevant gait situations (walking on stairs and slopes, walking backwards, walking with small steps, simulated perturbations of swing phase extension) were investigated in a motion analysis laboratory with six unilateral transfemoral amputees using two different microprocessor-controlled prosthetic knee joints (Rheo Knee XC, C-Leg). A randomized crossover design was chosen. The study results imply that the performance and safety potential of a microprocessor-controlled knee joint can be associated with the individual control algorithms and the technological concepts that are implemented to generate motion resistances for controlling flexion and extension movements...

BACKGROUND: For children with life-shortening illness, achieving a "good death" can be a tacit goal. There is little understanding of how different stakeholders perceive what a "good death" might be. OBJECTIVE: To review empirical literature to construct an understanding of a "good death" for children with life-shortening conditions. DESIGN: An integrative review approach was followed. This involved searching across Embase, Web of Science, Medline, CINAHL, and PsycINFO (no date limits set), as well as identifying eligible studies tracking reference lists...

Improving luminescent intensity is a significant technical requirement and scientific problem for the luminescent performance of fluorophor materials through the ages. The process control and luminescence performance still limit the developments of luminescent intensity even through it can be improved partly by covering or magnetron sputtering of precious metals on the surface of the fluorophore materials. On the basis of the improvement of luminescence center radiative transition rate by surface plasma resonance and Y2 O3 :Eu3+ microsheet phosphors, a fundamental model for topological luminophor Y2 O3 :Eu3+ +Ag was designed referencing the concepts of topological materials in order to enhance luminescent performance by composite-luminescence, which composed of Eu3+ centric electroluminescence and surface plasma-enhanced photoluminescence by Ag...

Cocrystals and isomers, two well-known unique concepts in supramolecular chemistry, are rarely put together until now. For the first time, we report three unprecedented and interesting cocrystals of twin isomers of coordination polymers (CPs) in situ formed by typical Keggin anions and Cu(II)-4,4'-bis(hydroxymethyl)-2,2'-bipyridine (Cu(II)-H2 L) complex moieties. In cocrystals 1-3, the Cu(II)-H2 L complex moieties are quadrisupported on Keggin-type anions through W(Mo)-Ot-Cu-Ot-W(Mo) (Ot is the terminal O atom) links in the crystal to form two twin ionic/neutral CPs with a fixed chemical stoichiometry...

INTRODUCTION: Our study is based on the concept that mental disorders - including psychotic symptoms - should be treated as dimensions/continuums rather than categories; an approach supported in the DSM-5 as well. Consequently, the measurement of certain symptoms of psychosis (e.g. hallucinations, persecutory ideation) may also be important in the normal population. We have performed the Hungarian adaptation of two questionnaires - the Persecutory Ideation Questionnaire and the Launay-Slade Hallucination Scale - in the current study and we also examined the relationship of the consumption of various caffeinated beverages, caffeine use disorder, the tendency to hallucinations and persecutory ideations...

Åsa B Gustafsson, Gerald W Dorn
The central functions fulfilled by mitochondria as both energy generators essential for tissue homeostasis and gateways to programmed apoptotic and necrotic cell death mandate tight control over the quality and quantity of these ubiquitous endosymbiotic organelles. Mitophagy, the targeted engulfment and destruction of mitochondria by the cellular autophagy apparatus, has conventionally been considered as the mechanism primarily responsible for mitochondrial quality control. However, our understanding of how, why, and under what specific conditions mitophagy is activated has grown tremendously over the past decade...

Rachel A Bergstrom
Science, technology, engineering, and math (STEM) continue to work to increase the diversity of the fields, yet there are still significant historical and societal hurdles to be overcome before we reach full representation throughout STEM. The concept of science identity has become a point of interest in this process; it has been suggested that development of one's identity as a scientist is critical to persistence in the field. Metaphors that are rooted in bodily experience can provide a starting point to understand abstract concepts, including science identity and how we as STEM educators respond to increasing diversity within our fields...
