Psychometric properties of a new ADHD screening questionnaire: Parent report on the (potential) underlying explanation of inattention in their school-aged children

ABSTRACT The present study examined psychometric properties of a recently developed parent report screening questionnaire, i.e., Parent ADHD Screening questionnaire: Signaling the Core explanation underlying behavioral symptoms (PASSC). The PASSC aims to measure (1) ADHD symptoms and (2) what parents view to be the main underlying explanation(s) of these symptoms. The PASSC questions 3 (potential) underlying explanations based on the triple pathway model (TPM): i.e., time, cognition and/or motivation problems. Parents of 1166 Dutch children aged 4–12 filled in the PASSC, as well as 2 questionnaires measuring time, cognition and motivation (i.e., the FTF and the SPSRQ-C). Reliability of the PASSC is good, indicated by high internal consistency of the sumscores. Principal component analyses supported the distinction between inattention and hyperactivity-impulsivity symptoms as defined in the DSM-5, and the distinction between the 3 TPM explanations given by parents for inattention, but not for hyperactivity-impulsivity symptoms. The majority of parents selected one and the same explanation for inattention problems of their child, most often being cognition (31.2%) and motivation (28.2%). PASSC validity was further supported by positive associations between the explanation sumscores for inattention symptoms and other parent questionnaires measuring the same constructs (i.e., time, cognition and motivation; convergent validity), although we found no evidence for discriminant validity. Groups (based on age group, sex and ADHD diagnosis) differed on the PASSC sumscores in the expected directions. Concluding, the PASSC is a promising tool to assess a child’s ADHD symptoms as well as the parent view on (potential) explanation(s) of inattention.
Post-stress glucose consumption facilitates hormesis and resilience to severe stress

Abstract Oral ingestion of a glucose solution following severe stress is a simple and effective way of preventing several of the negative sequelae of stress in rats. Similar resilience is obtained through hormetic training – pre-exposure to mild-to-moderate stress prior to severe stress. Here, we examined whether hormetic training is facilitated when a glucose solution is available following each hormetic training session. In Experiment 1, all rats were pre-exposed to a 30 min hormetic session of 25 inescapable tailshocks on each of 3 days. The schedule or hormesis differed between groups. The hormetic sessions occurred on either 3 consecutive days or with an interpolated day of rest between each hormetic session. Furthermore, in each of these conditions, one group had access to water and one group had access to a 40% glucose solution immediately after each hormetic session to complete a 2x2 factorial design. All groups were exposed to 100 inescapable tailshocks on the day following the end of hormetic training. Shuttle-escape testing occurred 24 h later. In Experiment 2, rats received two consecutive days of 100 inescapable tailshocks. Water or glucose was available following each session. Testing occurred 24 h after the second shock exposure. Experiment 1 replicated previous findings that rats exposed to hormetic training with interpolated rest did not show exaggerated fear responding or shuttle-escape deficits that normally result from 100 inescapable tailshocks, but training was ineffective if no rest was given between stress sessions. However, all post-stress glucose groups showed an elimination of helpless behavior. In Experiment 2, it was revealed that even 100 tailshocks can be made hormetic by post-stress glucose consumption.
A case series of intra-articular diffuse pigmented villonodular synovitis of the knee: Prognosis of complete synovectomy under arthroscopic surgery

Purpose: The purpose of this study is to evaluate the outcome and prognosis of complete synovectomy performed under arthroscopic surgery in the treatment of diffuse pigmented villonodular synovitis (DPVNS) of the knee. Methods: We retrospectively reviewed 7 cases (6 female and 1 male) diagnosed with diffuse pigmented villonodular synovitis (DPVNS) of knee from 2013 to 2017. All of these cases were treated with knee arthroscopy-assisted complete synovectomy. The follow-up period ranged from 36 months to 60 months (average: 48.0 months). The pain score, range of motion and functional outcome of the knee joint were evaluated after surgery. Symptoms and signs were monitored and magnetic resonance imaging (MRI) were routinely requested to note for possible recurrence during clinical follow up. Results: During and after the surgeries of complete synovectomy under arthroscope by the same surgeon, no complications were noted in the ward or the clinic. Significant improvements were achieved in terms of the range of motion and Lysholm knee function score. There was no recurrence of DPVNS observed in our patients during a follow-up of 4 years. Conclusions: Intra-articular DPVNS of the knee can successfully be treated by complete synovectomy under arthroscope. This case series emphasized the technique of multiple portals and cycling different shavers to achieve satisfactory outcomes.
Short Term, Oral Supplementation with Optimized Curcumin Does Not Impair Performance Improvements Associated with High Intensity Interval Training

Abstract Curcumin may improve athletic performance through a reduction in inflammation following exercise and improve mental states of well-being. The purpose of this investigation was to explore the effects of a 14 day HIIT intervention and oral supplementation with Longvida® optimized curcumin on athletic performance, lactate response, and well-being. Sixteen males and twenty females participated in a double-blinded, randomized, placebo-controlled trial to explore the effects of Longvida(R) optimized curcumin (1.0 g/day) and or a placebo (PLA) taken daily during a 14 day HIIT protocol. Participants were randomized into two groups, then evaluated in three groups, curcumin-fast (CURF), curcumin-slow (CURS) and placebo. Curcumin-fast and curcumin-slow were separated by their 16.1 km cycling time trial performance (TT) with CURF and CURS determined by a TT <30 min and >30 min at the pre intervention time point, respectively. Cycling time-trial performance, blood lactate response, and well-being assessments were determined at pre and post 14 day HIIT intervention time points. Blood lactate was recorded at baseline, 8.01 km, 15.1 km, and 1 min post, and 4 min post of the pre and post intervention TT. Following the internvetion, CONP and CURS experienced with 8.15% and 5.04% improvements in TT performance times, while CURF experienced a 0.57% improvement in TT performance time. No changes were observed with respect to other measures. When curcumin is taken daily in conjunction with 14 days of HIIT on a cycle ergometer, cycling performance in either well trained or more recreationally trained athletes is not impaired. Although the improvements in TT performance were not stasticially significant, they are noteworthy.
Major genetic discontinuity and novel toxigenic species in Clostridioides difficile taxonomy

Clostridioides difficile infection (CDI) remains an urgent global One Health threat. The genetic heterogeneity seen across C. difficile underscores its wide ecological versatility and has driven the significant changes in CDI epidemiology seen in the last 20 years. We analysed an international collection of over 12,000 C. difficile genomes spanning the eight currently defined phylogenetic clades. Through whole-genome average nucleotide identity, and pangenomic and Bayesian analyses, we identified major taxonomic incoherence with clear species boundaries for each of the recently described cryptic clades CI–III. The emergence of these three novel genomospecies predates clades C1–5 by millions of years, rewriting the global population structure of C. difficile specifically and taxonomy of the Peptostreptococcaceae in general. These genomospecies all show unique and highly divergent toxin gene architecture, advancing our understanding of the evolution of C. difficile and close relatives. Beyond the taxonomic ramifications, this work may impact the diagnosis of CDI.
Long-term proton pump inhibitor use is a risk factor for mortality in patients hospitalized for COVID-19

Background and aim The aim of this study is to evaluate whether the long-term (≥4 weeks) use of proton pump inhibitors (PPIs) is a risk factor for intubation requirement and mortality in patients hospitalized for COVID-19. Materials and methods In this multicentric retrospective study, a total of 382 adult patients (≥18 years of age) with confirmed COVID-19 who were hospitalized for treatment were enrolled. The patients were divided into two groups according to the periods during which they used PPIs: the first group included patients who were not on PPI treatment, and the second group included those who have used PPIs for more than 4 weeks Results The study participants were grouped according to their PPI usage history over the last 6 months. In total, 291 patients did not use any type of PPI over the last 6 months, and 91 patients used PPIs for more than 4 weeks. Older age (HR: 1.047, 95% CI: 1.026–1.068), current smoking (HR: 2.590, 95% CI: 1.334–5.025), and PPI therapy for more than 4 weeks (HR: 1.83, 95% CI: 1.06–2.41) were found to be independent risk factors for mortality Conclusion The results obtained in this study show that using PPIs for more than 4 weeks is associated with negative outcomes for patients with COVID-19. Patients receiving PPI therapy should be evaluated more carefully if they are hospitalized for COVID-19 treatment.
Objects that direct visuospatial attention produce the search advantage for facing dyads.

When hidden among pairs of individuals facing in the same direction, pairs of individuals arranged front-to-front are found faster in visual search tasks than pairs of individuals arranged back-to-back. Two rival explanations have been advanced to explain this search advantage for facing dyads. According to one account, the search advantage reflects the fact that front-to-front targets engage domain-specific social interaction processing that helps stimuli compete more effectively for limited attentional resources. Another view is that the effect is a by-product of the ability of individual heads and bodies to direct observers' visuospatial attention. Here, we describe a two-part investigation that sought to test these accounts. First, we found that it is possible to replicate the search advantage with nonsocial objects. Next, we employed a cuing paradigm to investigate whether it is the ability of individual items to direct observers' visuospatial attention that determines if an object category produces the search advantage for facing dyads. We found that the strength of the cuing effect produced by an object category correlated closely with the strength of the search advantage produced by that object category. Taken together, these results provide strong support for the directional cuing account. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
Final Overall Survival Analysis of the TOURMALINE-MM1 Phase III Trial of Ixazomib, Lenalidomide, and Dexamethasone in Patients With Relapsed or Refractory Multiple Myeloma

PURPOSE The double-blind, placebo-controlled, phase III TOURMALINE-MM1 study demonstrated a statistically significant improvement in progression-free survival with ixazomib-lenalidomide-dexamethasone (ixazomib-Rd) versus placebo-Rd in patients with relapsed or refractory multiple myeloma. We report the final analyses for overall survival (OS). PATIENTS AND METHODS Patients were randomly assigned to ixazomib-Rd (n = 360) or placebo-Rd (n = 362), stratified by number of prior therapies (1 v 2 or 3), previous proteasome inhibitor (PI) exposure (yes v no), and International Staging System disease stage (I or II v III). OS (intent-to-treat population) was a key secondary end point. RESULTS With a median follow-up of 85 months, median OS with ixazomib-Rd versus placebo-Rd was 53.6 versus 51.6 months (hazard ratio, 0.939; P = .495). Lower hazard ratios, indicating larger magnitude of OS benefit with ixazomib-Rd versus placebo-Rd, were seen in predefined subgroups: refractory to any (0.794) or last (0.742) treatment line; age > 65-75 years (0.757); International Staging System stage III (0.779); 2/3 prior therapies (0.845); high-risk cytogenetics (0.870); and high-risk cytogenetics and/or 1q21 amplification (0.862). Following ixazomib-Rd versus placebo-Rd, 71.7% versus 69.9% of patients received ≥ 1 anticancer therapy, of whom 24.7% versus 33.9% received daratumumab and 71.8% versus 76.9% received PIs (next-line therapy: 47.5% v 55.8%). Rates of new primary malignancies were similar with ixazomib-Rd (10.3%) and placebo-Rd (11.9%). There were no new or additional safety concerns. CONCLUSION Median OS values in both arms were the longest reported in phase III studies of Rd-based triplets in relapsed or refractory multiple myeloma at the time of this analysis; progression-free survival benefit with ixazomib-Rd versus placebo-Rd did not translate into a statistically significant OS benefit on intent-to-treat analysis. OS benefit was greater in subgroups with adverse prognostic factors. OS interpretation was confounded by imbalances in subsequent therapies received, especially PIs and daratumumab.
TRANSPORT COEFFICIENTS OF PARTIALLY IONISED GASES: A REVISITATION

A literature survey is undertaken to assess the state of the art in the calculation of transport properties of partially ionised gases in magnetic fields. The motivation for the study is to insert the expressions for the transport coefficients into calculations of hypersonic flows, therefore the focus is on the hydrodynamic regime and on the Chapman-Enskog method. Previous results are discussed and compared and recommendations for practical calculations are given. Finally, sample results on the modifications introduced in the viscosity tensor by the presence of the magnetic field are reported.
Electroacupuncture Pretreatment at Neiguan (PC6) attenuates autophagy in rats with myocardial ischemia reperfusion through the phosphatidylinositol 3-kinase-Akt-mammalian target of rapamycin pathway.

OBJECTIVE To investigate the protective efficacy of electroacupuncture (EA) pretreatment at Neiguan (PC6) on myocardial ischemia-reperfusion (I/R) in rats. METHODS Fifty rats were randomly divided into five groups (n = 10): sham operation group, model group (underwent in vivo myocardial I/R), EA pretreatment group [EA at Neiguan (PC 6) 1 week before I/R], wortmannin group (1 week before I/R, the PI3K inhibitor, wortmannin, was injected), EA pretreatment + wortmannin group (both pretreatments were performed simultaneously). After establishing the I/R model, 2,3,5-triphenyltetrazolium chloride (TTC) staining was used to analyze the weight and area of the myocardial infarction tissue. The biosignal and pressure test system was used to determine the left ventricular systolic mean pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), fractional shortening (FS), and ejection fraction (EF). Ultraviolet spectrophotometry was used to determine the expression of creatine kinase (CK)-MB, inducible nitric oxide synthase (iNOS), and total antioxidant capacity (T-AOC) in the serum. The expression of autophagy-related protein 13 (ATG13), mammalian target of rapamycin (mTOR), and phosphatidylinositol 3-kinase (PI3K) in cardiac muscle cells was determined by immunofluorescence. Hematoxylin and eosin staining was used to observe autophagy-related pathological changes in rat cardiomyocytes, and ultrastructural changes of cardiomyocytes were examined by transmission electron microscopy. RESULTS In this study, the infarction size and tissue weight of the EA pretreatment group were decreased compared with the model group (P < 0.0001). Furthermore, compared with the model group, the LVEDP values of the EA pretreatment group were significantly reduced (P = 0.0091), and the LVSP, FS, and EF values were slightly increased (P = 0.0007, 0.0020, 0.0031). EA pretreatment also significantly decreased the expression of CK-MB and iNOS, while it increased the expression of T-AOC in the serum of rats with I/R injury (P < 0.0001). Furthermore, EA pretreatment slightly widened the myocardial fiber space, reduced necrosis and myocardial cell swelling and maintained the nucleus and mitochondria structure intact. CONCLUSION EA pretreatment promoted autophagy flux and alleviated myocardial I/R injury through the PI3K-Akt-mTOR pathway.
Emerging topical therapies to treat pigmentary disorders: an evidence-based approach

Abstract Background Hyperpigmentation disorders are commonly encountered in dermatology clinics. The use of prescription-grade and over-the-counter topical lightening agents has increased in popularity, leading to a substantial growth of research over the past decade. Objective We seek to review clinical studies evaluating the use of different Rx-grade and OTC ingredients in treating hyperpigmentation. Methods and materials A comprehensive search on PubMed was conducted to identify patient-based evidence on the most common ingredients used as topical lightening agents: arbutin, ascorbic acid, cysteamine, hydroquinone, kojic acid, niacinamide, retinoids, and triple-combination therapy. The topicals were classified as either prescription-grade or over-the-counter. Results Varying levels of evidence support the use of topicals in treating hyperpigmentation. There were more clinical trials examining Rx-grade products than OTC products. Mild but tolerated side effects are noted in many of these agents. Conclusion Careful monitoring and adjustment of doses will be needed to maximize skin lightening benefits and minimize side effects.
In vitro Streptococcus mutans adhesion and biofilm formation on different esthetic orthodontic archwires.

OBJECTIVES To evaluate the ability of different esthetic archwires to retain oral biofilms in vitro. MATERIALS AND METHODS Seven different brands of coated orthodontic archwires were tested: two epoxy coated, two polytetrafluoroethylene coated, two rhodium coated, and one silver plus polymer coated. Conventional uncoated metallic archwires were used as controls. Streptococus mutans adherence to archwires was quantified by colony count following 24 hours of biolfilm growth, and total wire-associated biofilm was measured using a crystal violet staining assay. For both tests, two conditions were used: 0% sucrose and 3% sucrose. For statistical analysis, P < . 05 was considered as statistically significant. RESULTS For S. mutans colony forming units per biofilm, there were no statistically significant differences among the various archwires (P = .795 for 0% sucrose; P = .905 for 3% sucrose). Regarding total biofilm formed on archwires in the 3% sucrose condition, there were statistically significant differences in crystal violet staining only for the comparison between Niti Micro Dental White and Copper Ni-Ti wires (P < .05). CONCLUSIONS The clinical use of esthetic-coated orthodontic wires may be considered to have similar risks as uncoated archwires for biofilm retention.
Defect-Free Single-Layer Graphene by 10 s Microwave Solid Exfoliation and Its Application for Catalytic Water Splitting

Mass production of defect-free single-layer graphene flakes (SLGFs) by a cost-effective approach is still very challenging. Here, we report such single-layer graphene flakes (SLGFs) (>90%) prepared by a nondestructive, energy-efficient, and easy up-scalable physical approach. These high-quality graphene flakes are attributed to a novel 10 s microwave-modulated solid-state approach, which not only fast exfoliates graphite in air but also self-heals the surface of graphite to remove the impurities. The fabricated high-quality graphene films (∼200 nm) exhibit a sheet resistance of ∼280 Ω/sq without any chemical or physical post-treatment. Furthermore, graphene-incorporated Ni–Fe electrodes represent a remarkable ∼140 mA/cm2 current for the catalytic water oxidation reaction compared with the pristine Ni–Fe electrode (∼10 mA/cm2) and a 120 mV cathodic shift in onset potential under identical experimental conditions, together with a faradic efficiency of >90% for an ideal ratio of H2 and O2 production from water. All these excellent performances are attributed to extremely high conductivity of the defect-free graphene flakes.
iNKT cells coordinate immune pathways to enable engraftment in nonconditioned hosts

Immunotherapeutic iNKT cells interact with monocytes and T cells in human umbilical cord blood grafts to simultaneously limit inflammation while promoting hematopoietic activity. Invariant natural killer T (iNKT) cells are a conserved population of innate T lymphocytes that interact with key antigen-presenting cells to modulate adaptive T-cell responses in ways that can either promote protective immunity, or limit pathological immune activation. Understanding the immunological networks engaged by iNKT cells to mediate these opposing functions is a key pre-requisite to effectively using iNKT cells for therapeutic applications. Using a human umbilical cord blood xenotransplantation model, we show here that co-transplanted allogeneic CD4+ iNKT cells interact with monocytes and T cells in the graft to coordinate pro-hematopoietic and immunoregulatory pathways. The nexus of iNKT cells, monocytes, and cord blood T cells led to the release of cytokines (IL-3, GM-CSF) that enhance hematopoietic stem and progenitor cell activity, and concurrently induced PGE2-mediated suppression of T-cell inflammatory responses that limit hematopoietic stem and progenitor cell engraftment. This resulted in successful long-term hematopoietic engraftment without pretransplant conditioning, including multi-lineage human chimerism and colonization of the spleen by antibody-producing human B cells. These results highlight the potential for using iNKT cellular immunotherapy to improve rates of hematopoietic engraftment independently of pretransplant conditioning.
Nutrition habits and frequency of consumption of selected food products by the residents of urban and rural area from the Subcarpathian voivodeship.

Background The dynamic development and change of rural lifestyle patterns towards urban patterns has been noticeable since the second half of the 20th century. Nutrition, as well as the lifestyle in urban and rural areas, has undergone a process of urbanization, which is evidenced by the following an increasing number of overweight people. Objective The aim of the study was to compare eating habits and frequency of consumption of selected groups of products between the urban and rural residents from the Subcarpathian voivodeship. Material and methods The survey was carried out on a sample of 279 persons from urban and rural areas of Subcarpathian voivodeship. In this study, the diagnostic survey method consisting of 3 (different) parts was used. To check the significance of differences, U Mann-Whitney and Kruskal-Wallis tests were used; whereas correlations between variables were determined by the Spearman's rank of correlation coefficient and Pearson's chi-quadrat test. Results In the part concerning eating habits, statistically significant differences occurred among others; for the circumstances of eating meals, the most commonly consumed snacks, food processing techniques and the most frequently selected fat. In the part concerning the frequency of consumption of individual product groups, significant differences occurred among others; for dairy products, grain products, fast food, alcohol. There was a correlation between the frequency of consumption of individual products and socioeconomic status. Conclusions The quality of the diet and eating habits of urban and rural residents of Subcarpathian voivodeship does not differ significantly. The detected differences in eating habits were more influenced by the education and socioeconomic status of the examined group than the place of residence.
