BACKGROUND: Hallux rigidus is a common cause of foot pain in the elderly and has a negative impact on quality of life. Several operative treatment options are available for feet that are refractory to conservative treatment. Of these, total joint replacement and arthrodesis of the first metatarsophalangeal joint are the most commonly performed interventions. Nevertheless, it is still not known which intervention results in the best clinical outcome and the fewest complications. METHODS: PubMed/MEDLINE, Embase, and the Cochrane Library were systematically searched for studies assessing outcome with the American Orthopaedic Foot & Ankle Society-Hallux Metatarsophalangeal Interphalangeal (AOFAS-HMI) score, Foot Function Index (FFI), visual analog scale (VAS) for pain, or Short Form-36 (SF-36) in patients who underwent an arthrodesis or total joint replacement for the treatment of symptomatic hallux rigidus...

Species establishing outside their natural range, negatively impacting local ecosystems, are of increasing global concern. They often display life-history features characteristic for r-selected populations with fast growth and high reproduction rates to achieve positive population growth rates (r) in invaded habitats. Here, we demonstrate substantially earlier maturation at a 2 orders of magnitude lower body mass at first reproduction in invasive compared to native populations of the comb jelly Mnemiopsis leidyi...

INTRODUCTION: Patients with symptomatic spondylolisthesis are frequently treated with nerve root decompression, in addition to pedicle screw fixation and interbody fusion. Minimally invasive approaches are gaining attention in recent years, although there is no clear evidence supporting the proclamation of minimally invasive spine surgery (MISS) being better than open surgery. We present the design of the MISOS (Minimal Invasive Surgery versus Open Surgery) trial on the effectiveness of MISS versus open surgery in patients with degenerative or spondylolytic spondylolisthesis...

Diabetes mellitus (DM) is a chronic metabolic disorder that requires regular medical care to prevent severe complications. The elevated blood glucose level affects the eyes, blood vessels, nerves, heart, and kidneys after the onset. The affected blood vessels (usually due to atherosclerosis) may lead to insufficient blood circulation particularly in the lower extremities and nerve damage (neuropathy), which can result in serious foot complications. Hence, an early detection and treatment can prevent foot complications such as ulcerations and amputations...

In response to heart failure (HF), the heart reacts by repressing adult genes and expressing fetal genes, thereby returning to a more fetal-like gene profile. To identify genes involved in this process, we carried out transcriptional analysis on murine hearts at different stages of development and on hearts from adult mice with HF. Our screen identified Oplah, encoding for 5-oxoprolinase, a member of the γ-glutamyl cycle that functions by scavenging 5-oxoproline. OPLAH depletion occurred as a result of cardiac injury, leading to elevated 5-oxoproline and oxidative stress, whereas OPLAH overexpression improved cardiac function after ischemic injury...

"The Decameron" by Giovanni Boccaccio is a work which stands between the Middle Ages and Modernity. There are theories which postulate that concepts of identity and individuality, which arose with the dawn of Modernity, have an influence on mental illness. We chose a hermeneutic approach towards "The Decameron" to analyse the depiction of a changing society, of love, mental suffering and the role of therapeutic interventions. We conclude that Boccaccio showed an interest in intrapsychic mechanisms, an idea pertaining to Modernity, and discuss this idea in light of today's psychiatry and Karl Jaspers' concept of "genetic understanding"...

Activity-based protein profiling has emerged as a powerful tool for visualizing glycosidases in complex biological samples. Several configurational cyclophellitol isomers have been shown to display high selectivity as probes for glycosidases processing substrates featuring the same configuration. Here, a set of deoxygenated cyclophellitols are presented which enable inter-class profiling of β-glucosidases and β-galactosidases.

The Moon bears a striking compositional and isotopic resemblance to the bulk silicate Earth (BSE) for many elements, but is considered highly depleted in many volatile elements compared to BSE due to high-temperature volatile loss from Moon-forming materials in the Moon-forming giant impact and/or due to evaporative loss during subsequent magmatism on the Moon. Here, we use high-pressure metal-silicate partitioning experiments to show that the observed low concentrations of volatile elements sulfur (S), selenium (Se), tellurium (Te), and antimony (Sb) in the silicate Moon can instead reflect core-mantle equilibration in a largely to fully molten Moon...

Under conditions of homeostasis, dynamic changes in the length of individual adherens junctions (AJs) provide epithelia with the fluidity required to maintain tissue integrity in the face of intrinsic and extrinsic forces. While the contribution of AJ remodeling to developmental morphogenesis has been intensively studied, less is known about AJ dynamics in other circumstances. Here, we study AJ dynamics in an epithelium that undergoes a gradual increase in packing order, without concomitant large-scale changes in tissue size or shape...

BACKGROUND: Single biomarker approaches provide only moderate accuracy in the non-invasive detection of exercise-induced myocardial ischemia. We therefore assessed the combination of the two most promising single biomarkers: high-sensitivity cardiac troponin I (hs-cTnI) and B-type natriuretic peptide (BNP). METHODS: Consecutive patients with suspected myocardial ischemia referred to stress myocardial perfusion single-photon emission tomography imaging (MPI) were enrolled...

We determined the temporal effects of neurohormonal antagonists and loop diuretics on serially assessed (3-monthly) cardio-renal biomarkers, functional status, and clinical outcomes in 250 patients with chronic heart failure (CHF) with reduced ejection fraction. In blood, we measured NT-proBNP, troponin T, C-reactive protein, creatinine, cystatin C; in urine, N-acetyl-beta-d-glucosaminidase and kidney-injury-molecule-1. ACE-inhibitors/ARB were inversely associated with cardiac impairment, inflammation and renal tubular damage, but not with glomerular dysfunction...

Background -The European Society of Cardiology (ESC) recommends a 0/1h-algorithm for rapid rule-out and rule-in of Non-ST-Segment-Elevation Myocardial Infarction (NSTEMI) using high-sensitivity cardiac troponin (hs-cTn) concentrations irrespective of renal function. As patients with renal dysfunction (RD) frequently present with increased hs-cTn concentrations even in absence of NSTEMI, concern has been raised regarding the performance of the 0/1h-algorithm in RD. Methods -In a prospective multicenter diagnostic study enrolling unselected patients presenting with suspected NSTEMI to the emergency department, we assessed the diagnostic performance of the ESC 0/1h-algorithm using hs-cTnT and hs-cTnI in patients with RD, defined as an estimated glomerular filtration rate below 60mL/min/1...

The superconducting properties of Ag1-xMo6S8 [x = 0.08(1)] Chevrel phase [Tc = 7.9(5) K] are studied on a sample compacted by spark plasma sintering. Both lower [Bc1 = 12(1) mT] and the upper [Bc2(0) ≈ 7.4(9) T] critical magnetic fields are obtained from magnetization and electrical resistivity measurements for the first time. The analysis of the low-temperature electronic specific heat indicates Ag1-xMo6S8 to be a two band superconductor with the energy gaps Δ1 = 1.6 meV (95 %) and Δ2 = 0.7 meV (5 %). Theoretical DFT calculations reveal a much stronger electron-phonon coupling in the studied Chevrel phase compared to earlier reports...

Visual cues can be used to train walking patterns. Here, we studied the performance and learning capacities of healthy subjects executing a high-precision visuomotor walking task, in an augmented reality training set-up. A beamer was used to project visual stepping targets on the walking surface of an instrumented treadmill. Two speeds were used to manipulate task difficulty. All participants (n = 20) had to change their step length to hit visual stepping targets with a specific part of their foot, while walking on a treadmill over seven consecutive training blocks, each block composed of 100 stepping targets...

During aging, skeletal muscle tissue progressively declines in mass, strength, and regenerative capacity. Decreased muscle stem cell (MuSC) number and impaired function might underlie the aging-related muscle wasting and impaired regenerative capacity. As yet, the search for factors that regulate MuSC fate and function has revealed several biochemical factors within the MuSC niche that may be responsible for the decline in MuSC regenerative capacity. This decline cannot be explained by environmental factors solely, as the MuSC potential to regenerate muscle tissue is not reversed by changing the biochemical MuSC niche composition...

There is a paucity of data regarding the impact of drug use on HIV suppression and care retention among adolescents and young adults (AYAs). We recruited a clinic-based sample of HIV infected AYAs to assess the prevalence of self-reported drug use. Clinical data, including retention and viral suppression, were abstracted from the electronic medical record. Logistic regression was used to evaluate marijuana and illicit drug use associations and to identify other risk factors. Of 200 participants (mean age 21, 2...

This study compared psychoacoustic reverberance parameters to each other, as well as to reverberation time (RT) and early decay time (EDT) under various acoustic conditions. The psychoacoustic parameters were loudness-based RT (TN), loudness-based EDT [EDTN; Lee, Cabrera, and Martens, J. Acoust. Soc. Am. 131, 1194-1205 (2012a)], and parameter for reverberance [PREV; van Dorp Schuitman, de Vries, and Lindau., J. Acoust. Soc. Am. 133, 1572-1585 (2013)]. For the comparisons, a wide range of sound pressure levels (SPLs) from 20 dB to 100 dB and RTs from 0...
