Could Periodontitis Aggravate Psoriasis?—An Update by Systematic Review

(1) Background: Psoriasis is a chronic and inflammatory systemic disease that has been associated with periodontal pathologies, specifically periodontitis. The aim of this research is to answer the following question: Could periodontitis aggravate psoriasis? (2) Methods: We carried out a systematic review following the PRISMA guide using PubMed, Embase, Scopus, and WOS; (3) Results: A total of 111 studies were identified in the databases and 11 were obtained after screening. The selection included nine case–control studies, one cross-sectional study, and one cohort study. Most of the publications report an increase in bleeding on probing and the presence of periodontal pockets in patients with psoriasis, confirming that inflammation caused by periodontitis can contribute to systemic inflammation worsening psoriasis. To summarize, the scientific literature indicates that local periodontal inflammation could aggravate psoriasis.
Authigenic and Detrital Carbonate Nd Isotope Records Reflect Pulses of Detrital Material Input to the Labrador Sea During the Heinrich Stadials

Limited constraints on the variability of the deep‐water production in the Labrador Sea complicate reconstructions of the strength of the Atlantic Meridional Overturning Circulation (AMOC) during the Late Quaternary. Large volumes of detrital carbonates were repeatedly deposited in the Labrador Sea during the last 32 kyr, potentially affecting radiogenic Nd isotope signatures. To investigate this the Nd isotope compositions of deep and intermediate waters were extracted from the authigenic Fe‐Mn oxyhydroxide fraction, foraminiferal coatings, the residual silicates and leachates of dolostone grains. We provide a first order estimation of Nd release via dissolution of detrital carbonates and its contribution to the authigenic ԑNd signatures in the Labrador Sea. During the Last Glacial Maximum the Nd isotope signatures in the Labrador Sea would allow active water mass mixing with more radiogenic ɛNd values (−12.6 and −14) prevailing in its eastern part whereas less radiogenic values (ɛNd ∼ −18.4) were found on the western Labrador slope. The deposition of detrital carbonates during Heinrich stadials (2,1) was accompanied by negative detrital and authigenic Nd isotope excursions (ɛNd ∼ −31) that were likely controlled by dissolution of dolostone or dolostone associated mineral inclusions. This highly unradiogenic signal dominated the authigenic phases and individual water masses in the Labrador Sea, serving as potential source of highly unradiogenic Nd to the North Atlantic region, while exported southward. The Holocene authigenic ɛNd signatures of the coatings and leachates significantly differed from those of the detrital silicates, approaching modern bottom water mass signatures during the Late Holocene.
Athletes’ perceptions of unsupportive parental behaviours in competitive female youth golf

Abstract Research exploring athletes and coaches’ perceptions of parent involvement in youth sport has demonstrated the presence of maladaptive parent involvement in youth sport. This research has provided insights into inappropriate parenting practices displayed in the youth sport environment. However, representative of the broader sport parenting literature, data has been primarily gleaned from sports such as tennis and football. In a bid to diversify participant populations, the present study sought to examine female youth golfers’ views of unsupportive parental behaviors within the competitive youth golf environment. Fourteen online synchronous focus groups were conducted with 61 female youth golfers in the specializing (n = 27) and investment (n = 34) stages of development, recruited from seven countries across three continents (Australia, Canada, England, Finland, Ireland, New Zealand, and Scotland). Reflexive thematic analysis revealed three higher-order categories of unsupportive parental behaviors: Emotional Ill-Treatment; Physical Ill-Treatment; and Pressurizing Behavior. Parenting practices consistent with emotional ill-treatment (e.g., verbal ill-treatment) have been previously discussed within the sport parenting literature, however the presence of physical ill-treatment displayed by parents toward child-athletes has not been commonly reported. The present research provides novel insights into athletes’ perceptions of these maladaptive behaviors, and demonstrates that, similar to other youth sports, unsupportive parental behaviors are evident in the youth golf environment. The findings of the current research further reinforce the need for reporting mechanisms for allegations of abuse within youth sport, continued stakeholder education, the development of safeguarding cultures, and also the need to explore parents’ experiences of exhibiting maladaptive involvement. Lay summary: Female youth golfers’ views of unsupportive parental behaviors in the specializing and investment stages of development were explored. Three higher order categories of unsupportive parental behaviors in competitive youth golf were identified: Emotional Ill-Treatment; Physical Ill-Treatment; and Pressurizing Behavior. IMPLICATIONS FOR PRACTICE Findings highlight the need for applied practitioners to work with sport organizations in developing and implementing holistic safeguarding cultures, to prevent child maltreatment in youth sport. Findings can be utilized by applied practitioners, governing bodies, and sport organizations to inform the content of future educational resources and programs for parents of youth golfers,
Unsteady Free-Convection Flow on a Vertical Oscillating Porous Plate With Constant Heating

In this paper, we consider the unsteady free-convection flows of a viscous and incompressible fluid near an oscillating porous infinite vertical plate (or wall) during the heating of the plate. The governing equations are solved in closed form by the Laplace transform technique, when the Prandtl number (Pr) of the fluid is arbitrary and the suction (or injection) is constant. This solution is applied for a special case of the constant heating effects from the harmonically oscillating plate. The resulting velocity and temperature are shown graphically and are also discussed for the case of air (Pr=0.71) or water (Pr=7.0) flows.
Application of Repetitive Transcranial Magnetic Stimulation in Neuropathic Pain: A Narrative Review

Neuropathic pain, affecting 6.9–10% of the general population, has a negative impact on patients’ quality of life and potentially leads to functional impairment and disability. Repetitive transcranial magnetic stimulation (rTMS)—a safe, indirect and non-invasive technique—has been increasingly applied for treating neuropathic pain. The mechanism underlying rTMS is not yet well understood, and the analgesic effects of rTMS have been inconsistent with respect to different settings/parameters, causing insufficient evidence to determine its efficacy in patients with neuropathic pain. This narrative review aimed to provide an up-to-date overview of rTMS for treating neuropathic pain as well as to summarize the treatment protocols and related adverse effects from existing clinical trials. Current evidence supports the use of 10 Hz HF-rTMS of the primary motor cortex to reduce neuropathic pain, especially in patients with spinal cord injury, diabetic neuropathy and post-herpetic neuralgia. However, the lack of standardized protocols impedes the universal use of rTMS for neuropathic pain. rTMS was hypothesized to achieve analgesic effects by upregulating the pain threshold, inhibiting pain impulse, modulating the brain cortex, altering imbalanced functional connectivity, regulating neurotrophin and increasing endogenous opioid and anti-inflammatory cytokines. Further studies are warranted to explore the differences in the parameters/settings of rTMS for treating neuropathic pain due to different disease types.
A Newly Developed Chemically Defined Serum-Free Medium Suitable for Human Primary Keratinocyte Culture and Tissue Engineering Applications

In our experience, keratinocytes cultured in feeder-free conditions and in commercially available defined and serum-free media cannot be as efficiently massively expanded as their counterparts grown in conventional bovine serum-containing medium, nor can they properly form a stratified epidermis in a skin substitute model. We thus tested a new chemically defined serum-free medium, which we developed for massive human primary keratinocyte expansion and skin substitute production. Our medium, named Surge Serum-Free Medium (Surge SFM), was developed to be used alongside a feeder layer. It supports the growth of keratinocytes freshly isolated from a skin biopsy and cryopreserved primary keratinocytes in cultured monolayers over multiple passages. We also show that keratin-19-positive epithelial stem cells are retained through serial passaging in Surge SFM cultures. Transcriptomic analyses suggest that gene expression is similar between keratinocytes cultured with either Surge SFM or the conventional serum-containing medium. Additionally, Surge SFM can be used to produce bilayered self-assembled skin substitutes histologically similar to those produced using serum-containing medium. Furthermore, these substitutes were grafted onto athymic mice and persisted for up to six months. In conclusion, our new chemically defined serum-free keratinocyte culture medium shows great promise for basic research and clinical applications.
Telephone Referral to a Paediatric Emergency Department: Why Do Parents Not Show Up?

Medical call centres can evaluate and refer patients to an emergency department (ED), a physician or provide guidance for self-care. Our aim was (1) to determine parental adherence to an ED orientation after being referred by the nurses of a call centre, (2) to observe how adherence varies according to children’s characteristics and (3) to assess parents’ reasons for non-adherence. This was a prospective cohort study set in the Lausanne agglomeration, Switzerland. From 1 February to 5 March 2022, paediatric calls (<16 years old) with an ED orientation were selected. Life-threatening emergencies were excluded. Parental adherence was then verified in the ED. All parents were contacted by telephone to respond to a questionnaire regarding their call. Parental adherence to the ED orientation was 75%. Adherence decreased significantly with increasing distance between the place the call originated and the ED. The child’s age, sex and health complaints within calls had no effect on adherence. The three major reasons for non-adherence to telephone referral were: improvement in the child’s condition (50.7%), parents’ decision to go elsewhere (18.3%) and an appointment with a paediatrician (15.5%). Our results offer new perspectives to optimise the telephone assessment of paediatric patients and decrease barriers to adherence.
Upper Limb Assessment of People With Multiple Sclerosis With the Use of a Haptic Nine-Hole Peg-Board Test

In this work, a nine-hole peg-board test (NHPT) arrangement is implemented in a Virtual Environment with the use of a Haptic Interface that has the form of a small robotic arm. The Haptic NHPT is used as a mean for investigating the validity of a quantitative metric, which is based on smoothness maximization, as a possible assessment parameter for three dimensional reaching tasks. More specifically this study refers to the assessment of people with multiple sclerosis. The basic metric is developed by combining a neurophysical concept, which suggests that the three dimensional trajectories are piecewise planar, with the minimum jerk model (MJM) which in turn maximizes the smoothness along a predefined path. A total number of sixteen persons participated in the study. From these, nine were healthy young adults and seven were people with MS of various ages and at different stages of disease progress. All participants performed the exercise three times, of which only the second and third were used in the analyses. The results showed that the employed procedure was successful for developing a motion analysis metric for the smoothness in three dimensional trajectories. Also, a clear and traceable difference in performance appeared between the two groups, by using the developed assessment metric.Copyright © 2008 by ASME
Dynamic drying in the early-stage coalescence of droplets sitting on a plate

The early-stage coalescence of two sessile drops is investigated theoretically and experimentally. The coalescence of small sessile drops of diethylene glycol on silicon wafer is induced either by condensation or syringe deposition. The bridge geometry in directions parallel and perpendicular to the substrate, the bridge contact angle and the direct fluid velocity are simultaneously analyzed. The process is characterized by the nucleation and growth of a bridge between the two drops. Three stages are identified. i) An initial stage of dynamic drying where the capillary number Ca>0.02 and the contact line does not move appreciably. The bridge does not wet the solid and its size grows as time t perpendicularly to the substrate and as t1/2 parallel to the substrate. ii) A late stage where the contact line starts to move and where the bridge relaxes exponentially, making eventually the composite drop to be ellipsis like. This stage is followed by iii) a very slow evolution limited by the contact line motion where the drop relaxes to a circular shape with a dynamics that is 6 to 7 orders larger than bulk hydrodynamics predicts.
Asymmetrically Clipped Optical Hadamard Coded Modulation (ACO-HCM)

In many optical wireless communications systems, power efficiency is paramount. In others, flexibility is important. To achieve these goals, this paper presents a novel transmission scheme dubbed asymmetrically clipped optical Hadamard coded modulation (ACO-HCM). ACO-HCM combines the characteristics of real-valued non-negative orthogonal frequency-division multiplexing (OFDM) and Hadamard coded modulation (HCM). Unlike OFDM, which is based on the Fourier transform and therefore delivers a continuous waveform, ACO-HCM provides a discrete set of amplitudes. This feature is desirable for nonlinear channels. Error probabilities are analytically calculated for a linear receiver similar to the decorrelation receiver in direct-sequence code-division multiple access (DS-CDMA). Maximum-likelihood sequence estimation is also investigated and shown to outperform the linear receiver, particularly in the presence of a time-dispersive channel. The peak-to-average power ratio of ACO-HCM is derived for the electrical as well as the optical domain in closed form.
Magnetic Field Dependence of the Hall Effect and Magnetoresistance in Graphite Single Crystals

The Hall coefficient and magnetoresistance in purified (99.995%) natural graphite single crystals have been measured from 25 to 25 000 gauss at 298\ifmmode^\circ\else\textdegree\fi{}, 77\ifmmode^\circ\else\textdegree\fi{}, and 4.2\ifmmode^\circ\else\textdegree\fi{}K with the field oriented parallel to the hexagonal axis. Special care was taken in the micromanipulation and strain-free mounting of these small soft crystals. Fast minority carriers due to Fermi-surface warping were discovered by their effect on the low-field Hall coefficient behavior. The compensating effect between the majority electron and hole densities [(5-2) \ifmmode\times\else\texttimes\fi{}${10}^{18}$ ${\mathrm{cm}}^{\ensuremath{-}3}$ with $\frac{{n}_{e}}{{n}_{h}}=1.0\ensuremath{-}1.15$ over the above temperature range] and mobilities [(1.5-130)\ifmmode\times\else\texttimes\fi{}${10}^{4}$ ${\mathrm{cm}}^{2}$/v sec with $\frac{{\ensuremath{\mu}}_{e}}{{\ensuremath{\mu}}_{h}}=1.10\ensuremath{-}0.79$] makes the Hall coefficient very sensitive to the temperature, impurities, and field where it even changes sign. A quadratic low-field room-temperature magnetoresistance dependence progresses at higher fields to an impurity-insensitive ${H}^{1.78}$ behavior. The large magnetoresistance ratio of graphite (\ensuremath{\sim}${10}^{5}$ at 4.2\ifmmode^\circ\else\textdegree\fi{}K and 23 kilogauss), along with the appearance of de Haas-van Alphen type oscillations in these properties, demonstrates the small effective masses ($0.03{m}_{0}, 0.06{m}_{0}$) and long relaxation times (2.5\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}11}$ sec at 4.2\ifmmode^\circ\else\textdegree\fi{}K). The mobility follows a ${T}^{\ensuremath{-}1.2}$ law in the lattice-scattering region \ensuremath{\gtrsim}50\ifmmode^\circ\else\textdegree\fi{}K. Low-temperature results, showing carrier density differences and mobilities to be most sensitive to impurities, substantiate the relatively high purity of these crystals.
Assessing the Relative Performance of GNSS-R Flood Extent Observations: Case Study in South Sudan

Flooding is one of the deadliest and costliest natural disasters. Climate change-induced flooding events are increasing worldwide, disproportionately impacting low-income and developing communities. While early warning systems save lives, satellite-based observation systems are vital for the disaster relief and recovery phases. Current satellite-based operational flood products are largely based on either optical remote-sensing methods, which exhibit a limited ability to detect water through clouds and vegetation, or microwave remote sensing, which provides relatively low spatial and temporal resolution. New small satellite constellations using radar or GNSS reflectometry (GNSS-R) have been shown to enhance our ability to overcome these deficiencies. In this work, we quantify the performance of using GNSS-R measurements from the NASA Cyclone Global Navigation Satellite Systems (CYGNSS) satellite constellation to map surface water in South Sudan and the Sudd wetland in comparison with a set of representative operational products. We make quantitative comparisons of our results with operational flood products based on Visible Infrared Imaging Radiometer Suite (VIIRS) and MODIS and with C-band Sentinel-1 synthetic aperture radar. We find that our method detects 35.4% more surface water than Sentinel-1, while the VIIRS- and MODIS-based products underestimate by 4.8% and 83.7%, respectively. We use several metrics commonly used to evaluate classification performance: precision, true positive rate (TPR), true negative rate (TNR), F2-score, and the Matthews correlation coefficient (MCC) and assess the comparisons in this statistical framework. We discuss the consequences of our findings, including ways CYGNSS data may enhance current flood products and assist decision-makers and emergency managers.
Decision-Making During High-Risk Events: A Systematic Literature Review

Effective decision-making in crisis events is challenging due to time pressure, uncertainty, and dynamic decisional environments. We conducted a systematic literature review in PubMed and PsycINFO, identifying 32 empiric research papers that examine how trained professionals make naturalistic decisions under pressure. We used structured qualitative analysis methods to extract key themes. The studies explored different aspects of decision-making across multiple domains. The majority (19) focused on healthcare; military, fire and rescue, oil installation, and aviation domains were also represented. We found appreciable variability in research focus, methodology, and decision-making descriptions. We identified five main themes: (1) decision-making strategy, (2) time pressure, (3) stress, (4) uncertainty, and (5) errors. Recognition-primed decision-making (RPD) strategies were reported in all studies that analyzed this aspect. Analytical strategies were also prominent, appearing more frequently in contexts with less time pressure and explicit training to generate multiple explanations. Practitioner experience, time pressure, stress, and uncertainty were major influencing factors. Professionals must adapt to the time available, types of uncertainty, and individual skills when making decisions in high-risk situations. Improved understanding of these decisional factors can inform evidence-based enhancements to training, technology, and process design.
Geodesic flows, interval maps, and symbolic dynamics

Geodesic flows and interval maps are two topics in the theory of dynamical systems with a long mathematical history. The first of these seems to have originated with Jacobi who related the flows to the study of Hamiltonian systems (for a detailed description of the connection, see [CFS]). The second arises in diverse settings, such as the modelling of population genetics [Ma] and the frequency count of digits in continued fraction expansions [Bi]. In both subjects the main problem is to describe the distribution of orbits. Thus we wish to know how the geodesies spread over the manifold containing them and how iterates of points under an interval map vary over the interval. Ergodic theory provides answers to these questions, particularly the notions of ergodicity and invariant measure which will be elaborated below. At first sight the two topics seem unrelated, geodesic flow being a continuous time action and interval map a discrete one. Nevertheless, we shall relate them and their associated symbolic dynamics when the flow takes place on a compact surface of constant negative curvature. In this case we use a graphic approach enabling us to find a series of reductions from geodesic flow to interval map. In relating the topics, we show how each sheds light on the other. We use ergodicity of interval maps to prove ergodicity of flows and conversely. Furthermore, explicit formulas for invariant measures of interval maps can be derived from invariant measures for flows. This fact is interesting as there is a paucity of explicit formulas for invariant measures of interval maps. The steps in our reduction scheme are known to exist abstractly. However, for the dynamical systems considered here, the reductions are carried out by means of elementary geometry. Our graphic
Crowdsourcing infrastructures of green everyday life: how sustainable sharing, swapping and gardening initiatives in Vienna tackle the lack of transformative agency in eco-politics

ABSTRACT Empirical researchers of environmental alternative action organizations (EAAOs) have called for grounding two eco-political theories: David Schlosberg’s sustainable materialism (SM) and Ingolfur Blühdorn’s simulative politics (SP). In this article, I discuss results of an ethnographic study on a library of things, a cloth swapping initiative, and a community garden in the City of Vienna, Austria. Regarding SM, participants indeed suffer from a lack of substantive eco-political actions by liberal democratic institutions and themselves personally, however they barely convey a new materialist ontology. Regarding SP, participants indeed show an ambivalence towards consumer capitalism and ecological commitments, yet they tend to be highly critical and reflexive on the matter. Both theories are unable to detect that the EAAOs fill an eco-political lacuna in Vienna’s foundational economy: Via positive framing and flexible participation virtually everyone – the crowd – is invited to co-create sustainable routines. As such, they represent rudimentary infrastructures of green everyday life.
