Low back pain is common and relates to a variety of overlapping pathologies. Within the last few decades, almost every medical imaging modality has been applied in the evaluation of low back pain. Imaging of the spine has a high priority in the assessment of patients with low back pain, who seem to expect such procedures to be undertaken. However, the majority of conventional imaging techniques do not have adequate precision to identify the primary source of pain. Not only can this be frustrating to both clinicians and patients, but importantly, inadequate correlation between imaging findings and symptoms hampers the ability of clinicians to devise a specific treatment plan for the patient...

OBJECTIVES: Moral distress is a common experience among critical care professionals, leading to frustration, withdrawal from patient care, and job abandonment. Most of the studies on moral distress have used the Moral Distress Scale or its revised version (Moral Distress Scale-Revised). However, these scales have never been validated through factor analysis. This article aims to explore the factorial structure of the Moral Distress Scale-Revised and develop a valid and reliable scale through factor analysis...

Surgeons frequently report frustration and loss of efficiency with electronic medical record (EMR) systems. Together, surgery residents and a programmer at Augusta University created a rounds report (RR) summarizing 24 hours of vitals, intake/output, labs, and other values for each inpatient that were previously transcribed by hand. The objective of this study was to evaluate the RRs effect on surgery residents. Surgery residents were queried to assess the RRs impact. Outcome measures were time spent preparing for rounds, direct patient care time, educational activity time, rates of incorrect/incomplete data on rounds, and rate of duty hour violations...

The inability of physiologists to effect change in fisheries management has been the source of frustration for many decades. Close collaboration between fisheries managers and researchers has afforded our interdisciplinary team an unusual opportunity to evaluate the emerging impact that physiology can have in providing relevant and credible scientific advice to assist in management decisions. We categorize the quality of scientific advice given to management into five levels based on the type of scientific activity and resulting advice (notions, observations, descriptions, predictions and prescriptions)...

Gregor Mendel's "Experiments on Plant Hybrids" (1865/1866), published 150 years ago, is without doubt one of the most brilliant works in biology. Curiously, Mendel's later studies on Hieracium (hawkweed) are usually seen as a frustrating failure, because it is assumed that they were intended to confirm the segregation ratios he found in Pisum Had this been his intention, such a confirmation would have failed, since, unknown to Mendel, Hieracium species mostly reproduce by means of clonal seeds (apomixis). Here we show that this assumption arises from a misunderstanding that could be explained by a missing page in Mendel's first letter to Carl Nägeli...

Background: The low level of patient satisfaction recorded in many studies and, at the same time, the level of frustration and burnout, disclosed by medics in the perception of the patient as a ‘problem’, incline to look for the causes of inadequate relationship between physician and patient. Objective: The aim of this study was to evaluate the level of acceptance of the patient by the medical personnel. The research problem was the acceptance level which was within the range of the communication skills of the nurses and doctors...

Three rare-earth aryloxide ion pairs ([L1REOAr]+[B(C6F5)4]-; L1 = CH3C(2,6-iPr2C6H3N)CHC(CH3)(NCH2CH2PPh2); RE = Sc, Y, Lu; Ar = 2,6-tBu2C6H3) are reported, which feature RE/P combinations exhibiting frustrated Lewis pair (FLP)-like 1,4-addition reactions towards conjugated carbonyl substrates e.g. enone, ynone and acrylic substrates. Furthermore, these RE/P complexes are found to be effective catalysts for polymerizations of conjugated polar alkene monomers. Mechanistic studies reveal that the polymerizations are initiated by novel FLP-type 1,4-additions, rather than traditional and ubiquitous covalent RE-E (E = H, C, N, etc...

The dimesitylphosphinocyclopentene/HB(C6 F5 )2 -derived vicinal trans-1,2-P/B frustrated Lewis pair (FLP) 4 shows no direct phosphane-borane interaction. Toward some reagents it behaves similar to an intermolecular FLP; it cleaves dihydrogen, deprotonates terminal alkynes, and adds to organic carbonyl compounds including CO2 . It shows typical intramolecular FLP reaction modes (cooperative 1,1-additions) to mesityl azide, to carbon monoxide, and to NO. The latter reaction yields a persistent P/B FLPNO nitroxide radical, which undergoes H-atom abstraction reactions...

Our objective was to identify behaviors and contextual situations associated with negative affect observed in the interactions of children with and without ADHD and their real-life friends. We expected negative affect to be linked to rule violations and disagreements about the choice of games. Loss of game was associated with episodes of negative affect in a structured game. Negative appraisal of friend's ability was most frequently associated with negative affect during unstructured free play. Comparison children expressed greater frustration regarding their own abilities, whereas children with ADHD commented more frequently about the inabilities of their friends...

Ionic charge carrier formation and mobility, including the underlying conduction mechanisms, are investigated for phosphoric acid at water contents relevant for the acid's application as electrolyte in fuel cells. The high conductivity contribution from structural diffusion involving intermolecular proton transfer (∼97%) in neat phosphoric acid (H3PO4) passes through a maximum at this composition. Hydrogen bond network frustration (imbalance of the number of proton donors and acceptors), which is closely related to the appearance of structural diffusion, decreases with both elimination and addition of water...

Transport properties and hydration behavior of phosphoric acid/(benz)imidazole mixtures are investigated by diverse NMR techniques, thermogravimetric analysis (TGA) and conductivity measurements. The monomeric systems can serve as models for phosphoric acid/poly-benzimidazole membranes which are known for their exceptional performance in high temperature PEM fuel cells. (1)H- and (31)P-NMR data show benzimidazole acting as a strong Brønsted base with respect to neat phosphoric acid. Since benzimidazole's nitrogens are fully protonated with a low rate for proton exchange with phosphate species, proton diffusion and conduction processes must take place within the hydrogen bond network of phosphoric acid only...

Population-scale sequencing is increasingly uncovering large numbers of rare single-nucleotide variants (SNVs) in coding regions of the genome. The rarity of these variants makes it challenging to evaluate their deleteriousness with conventional phenotype-genotype associations. Protein structures provide a way of addressing this challenge. Previous efforts have focused on globally quantifying the impact of SNVs on protein stability. However, local perturbations may severely impact protein functionality without strongly disrupting global stability (e...

Alternative exercise traditions (AETs) such as Pilates, yoga, Tai Chi Chuan, Qigong, and various forms of dance offer the potential to improve diverse outcomes among cancer survivors by reducing adverse symptoms and mood disorders, and by enhancing function. Additionally AETs have emerged as a potential means to address deficits in current disease-focused care delivery models which are marked by prevalent under-treatment of symptoms and physical impairments. Relative to therapeutic exercise in allopathic models, many AETs are comparatively affordable and accessible...

BACKGROUND: There is very little information about the quality of life (QOL) of stroke survivors in LMIC countries with underdeveloped non communicable health infrastructures, who bear two thirds of the global stroke burden. METHODOLOGY: We used a sequential mix methods approach. First, a quantitative analytical cross-sectional study was conducted on 700 participants, who constituted 350 stroke survivor and their caregiver dyads. QOL of stroke survivor was assessed via Stroke Specific Quality of Life Scale (SSQOLS) whereas QOL of caregivers was assessed through RAND-36...

We prove that any nonzero inertia, however small, is able to change the nature of the synchronization transition in Kuramoto-like models, either from continuous to discontinuous or from discontinuous to continuous. This result is obtained through an unstable manifold expansion in the spirit of Crawford, which features singularities in the vicinity of the bifurcation. Far from being unwanted artifacts, these singularities actually control the qualitative behavior of the system. Our numerical tests fully support this picture...

We study the dynamics of network-coupled phase oscillators in the presence of coupling frustration. It was recently demonstrated that in heterogeneous network topologies, the presence of coupling frustration causes perfect phase synchronization to become unattainable even in the limit of infinite coupling strength. Here, we consider the important case of heterogeneous coupling functions and extend previous results by deriving analytical predictions for the total erosion of synchronization. Our analytical results are given in terms of basic quantities related to the network structure and coupling frustration...
