Exercise physiologists use of pain neuroscience education for treating knee osteoarthritis: A qualitative interview study

Abstract Objectives To explore how Australian exercise physiologists (EPs) utilise pain neuroscience education (PNE) in their management of patients with knee osteoarthritis. Methods A semi‐structured interview concerning a knee osteoarthritis vignette was designed to understand each participant's beliefs about physical activity, pain, injury and coping strategies and quantify their use of pain neuroscience concepts. Themes were derived from pre‐determined pain target concepts as well as others that emerged from thematic analysis. Results Thirty EPs (57% male, mean clinical experience 7 years (SD 7.1) participated in the semi‐structured interviews. 13 themes emerged. EPs primarily focussed on: (1) active treatment strategies are better than passive, (2) pain and tissue damage rarely relate, and (3) learning about pain can help individuals and society. Other themes included the use of biomedical‐based education, pain during exercise and delivery of PNE. Underutilised themes included the role of the brain in pain, validation that pain is real and personal, the concept of danger sensors as opposed to pain sensors, and pain depends on the balance between safety and danger. Conclusion EPs primarily advised on active treatment approaches (e.g. exercise and self‐management). Quality of care is likely to improve through increasing focus on the systemic benefits of exercise in overcoming psychological barriers (e.g. fear avoidance and pain catastrophising) that may prevent exercise treatment engagement. Broadening PNE to reconceptualise knee osteoarthritis pain as a sign of an overprotective nervous system, rather than structural damage, may facilitate greater patient engagement in exercise therapies, thus improving patient outcomes.
Brain mineralocorticoid receptor in health and disease: From molecular signalling to cognitive and emotional function

Brain mineralocorticoid receptors (MR) mediate effects of glucocorticoid hormones in stress adaptation, as well as the effects of aldosterone itself in relation to salt homeostasis. Brain stem MRs respond to aldosterone, whereas forebrain MRs mediate rapid and delayed glucocorticoid effects in conjunction with the glucocorticoid receptor (GR). MR‐mediated effects depend on age, gender, genetic variations, and environmental influences. Disturbed MR activity through chronic stress, certain (endocrine) diseases or during glucocorticoid therapy can cause deleterious effects on affective state, cognitive and behavioural function in susceptible individuals. Considering the important role MR plays in cognition and emotional function in health and disease, MR modulation by pharmacological intervention could relieve stress‐ and endocrine‐related symptoms. Here, we discuss recent pharmacological interventions in the clinic and genetic developments in the molecular underpinnings of MR signalling. Further understanding of MR‐dependent pathways may help to improve psychiatric symptoms in a diversity of settings.
Prevalence and risk factors associated with dry eye disease among adults in a population-based setting in South-West Nigeria

Background: Dry eye disease (DED) occurs as a result of an abnormality in tear production, tear consistency, and tear evaporation. Aim: The aim of this study is to determine the prevalence and risk factors associated with dry eye disease in a population-based setting in Southwest Nigeria. Patient and Methods: A cross-sectional study was conducted at a medical outreach at Iperu Remo in Nigeria. A systematic random sampling technique was used to select 415 participants. Symptoms of dry eye were evaluated using the Ocular Surface Disease Index questionnaire. Tear film break-up time (TBUT), fluorescein staining, Schirmer test with anesthesia, and meibomian gland were evaluated. The diagnosis of DED was confirmed when the OSDI score is ≥13 and TBUT is less than 10 seconds. Data were analyzed using descriptive statistics, Chi-square, and logistic regression analyses at a 0.05 level of significance. Results: The overall prevalence of DED was 28.2%. Adults aged between 31 and 40 years were 23 times more likely to be diagnosed with dry eyes (aOR = 23.13; 95% CI: 1.32 – 405.99; P = 0.032) compared to those between 16 and 20 years. Female adults were about four times more likely to be diagnosed with dry eyes (aOR = 3.59; 95% CI: 1.44 – 8.94; P = 0.006). The use of drugs was also significantly associated with dry eyes. Conclusion: This study shows a fairly high prevalence of DED among adults in a semi-urban area in Southwest Nigeria. Ophthalmologists and other eye care workers need to be cautious about the DED and offer appropriate treatment options to patients.
Power training alters somatosensory cortical activity of youth with cerebral palsy

Our prior magnetoencephalographic (MEG) investigations demonstrate that persons with cerebral palsy (CP) have weaker somatosensory cortical activity than neurotypical (NT) controls, which is associated with reduced muscular strength and mobility. Power training can improve lower extremity isokinetic strength, muscular power, and walking performance of youth with CP. Potentially, these clinically relevant improvements are partially driven by changes in somatosensory processing. The objective of this investigation was to determine if power training has complementary changes in muscular function and somatosensory cortical activity in youth with CP.
Effects of exercise training on obesity‐related parameters in people with intellectual disabilities: systematic review and meta‐analysis

Abstract Background Efforts to synthesise existing knowledge concerning the effects of exercise interventions on obesity (i.e. changes in body weight and composition) have been made, but scientific evidence in this matter is still limited. This systematic review and meta‐analysis aims to identify and critically analyse the best available evidence regarding the use of physical exercise as a strategy to attenuate obesity through its effects on adiposity‐related anthropometric parameters in people with intellectual disability (ID). Methods Following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines, a literature search was performed using PubMed, Scopus, SPORTDiscus, CINAHL and the Cochrane Library through specific keywords up to July 2020. The search adhered to the population, intervention, comparison and outcome strategy. Randomised controlled trials addressing the effects of the exercise intervention on adiposity‐related anthropometric parameters (body mass index, waist circumference, waist–hip ratio, fat percentage or body weight) in children, adolescents and adults with ID were included. The methodological quality of the studies found was evaluated through the PEDro scale. Results A total of nine investigations with children and/or adolescents (10–19 years) and 10 investigations with adults (18–70 years) were selected, mostly experiencing mild and moderate ID. Methodological quality was fair in 13 of these publications, good in five and excellent in one. Seventeen trials reported comparable baseline and post‐intervention data for the intervention and control groups and were included in the meta‐analysis. In nine studies, the intervention group performed a cardiovascular training programme. Five papers described a combined training programme. Two trials executed whole‐body vibration training programmes, and one publication proposed balance training as the primary intervention. According to the meta‐analysis results, the reviewed studies proposed exercise modalities that, in comparison with the activities performed by the participants' in the respective control groups, did not have a greater impact on the variables assessed. Conclusions While physical exercise can contribute to adiposity‐related anthropometric parameters in people with mild and moderate ID, these findings show that exercise alone is not sufficient to manage obesity in this population. Multicomponent interventions appear to be the best choice when they incorporate dietary deficit, physical activity increase and behaviour change strategies. Finding the most effective modality of physical exercise can only aid weight loss interventions. Future research would benefit from comparing the effects of different exercise modalities within the framework of a multicomponent weight management intervention.
Spirulina extract improves age-induced vascular dysfunction

Abstract Context Vascular dysfunction is considered a hallmark of ageing that has been associated with altered vasomotor responses, in which nitric oxide (NO) and reactive oxygen species participate. The consumption of Spirulina extracts, with antioxidant properties, increased recently. Objective This study investigates the effect of Spirulina aqueous extract (SAE) on the vascular function of the aorta from aged rats. Materials and methods Aortic segments from aged male Sprague-Dawley rats (20–22 months old) were exposed to SAE (0.1% w/v, for 3 h) to analyse: (i) the vasodilator response induced by acetylcholine (ACh), by the NO donor sodium nitroprusside (SNP), by the carbon monoxide releasing molecule (CORM) and by the KATP channel opener, cromakalim (CK); (ii) the vasoconstrictor response induced by KCl and noradrenaline (NA); (iii) the production of NO and superoxide anion, and (iv) the expression of the p-eNOS and HO-1 proteins. Results Incubation with SAE increased the expression of p-eNOS (1.6-fold) and HO-1 (2.0-fold), enhanced NO release (1.4-fold in basal and 1.9-fold in ACh-stimulated conditions) while decreased the production of superoxide (0.7-fold). SAE also increased the sensitivity (measured as pEC50) to ACh (control: −7.06 ± 0.11; SAE: −8.16 ± 0.21), SNP (control: −7.96 ± 0.16; SAE: −9.11 ± 0.14) and CK (control: −7.05 ± 0.39; SAE: −8.29 ± 0.53), and potentiated the response to KCl (1.3-fold) and to NA (1.7-fold). Conclusion The antioxidant properties of SAE improved the vasomotor responses of aorta from aged rats. These results may support the use of Spirulina as a protection against vascular dysfunction.
U.S. fires became larger, more frequent, and more widespread in the 2000s

Recent fires have fueled concerns that regional and global warming trends are leading to more extreme burning. We found compelling evidence that average fire events in regions of the United States are up to four times the size, triple the frequency, and more widespread in the 2000s than in the previous two decades. Moreover, the most extreme fires are also larger, more common, and more likely to co-occur with other extreme fires. This documented shift in burning patterns across most of the country aligns with the palpable change in fire dynamics noted by the media, public, and fire-fighting officials.
Protective and risk activities for emotional and behavioural well‐being of children and adolescents during the COVID‐19 lockdown

Abstract Background The lockdown imposed to contain the COVID‐19 pandemic brought deep changes in the daily life of Italian children and adolescents, increasing the time spent at home. This study aims to explore how activities that children and adolescents carried out at home during the lockdown were related to their emotional and behavioural well‐being. Method Parents completed an anonymous online survey on how much time their children and adolescents dedicated to social networks, solitary screen time, play time and to a series of parent–child dyadic activities. They also reported on their offspring's emotional difficulties and behavioural problems. Results The use of social networks had a negative impact on children's emotional difficulties, while it promoted well‐being in adolescents. Pertaining to solitary screen activities, these were associated with more behavioural problems in both children and adolescents. Regarding parent–child dyadic activities, get along with the parent was associated with less emotional difficulties and behavioural problems in children and with less behavioural problems in adolescents. Furthermore, for adolescents, the more they talked with the parent, the less behavioural problems they evidenced. Conclusion The current study may help to identify activities that could be promoted and those that should be limited to effectively menage home time, in order to ultimately safeguard the emotional and behavioural well‐being of children and adolescents.
Postoperative clinical outcomes and radiological healing according to deep and superficial layer detachment in first facet involving subscapularis tendon tear

Background Subscapularis tendon insertion at the first facet has separate layers (deep and superficial). The purpose of this study is to evaluate postoperative clinical outcomes and radiological healing according to each layer of detachment in the first facet involving subscapularis tendon tear. Methods Eighty-three patients who underwent arthroscopic repair due to First facet involving the scapularis tendon tear accompanying small to medium sized posterosuperior cuff tear were classified into three groups (group A: deep layer partial detachment, group B: deep layer complete detachment, but no superficial layer detachment, and group C: deep layer and superficial layer complete detachment). Subscapularis tendon healing was evaluated using computed tomography arthrogram and clinical result was evaluated using American Shoulder and Elbow Surgeons (ASES) shoulder score, Constant score and University of California Los Angeles (UCLA) shoulder score. Results Retear rate of the subscapularis tendon was 2.2%, 18.2%, and 33.3% in group A, group B, and group C, respectively. These rates showed statistically significant difference among the three groups, which were classified by deep and superficial layer detachment in the first facet (p=0.003). Group A showed significant difference in subscapularis tendon healing compared with group B and group C (p=0.018 and p<0.001, respectively), but there was no statistical difference between group B and group C (p=0.292). Regarding clinical outcomes, there was no significant difference among three groups in ASES and UCLA score at final follow-up (p=0.070 and p=0.106, respectively). Conclusions Complete detachment of deep layer may be related with retear occurrence regardless with detachment of superficial layer, but clinical outcome may not be related with each layer detachment in the first facet involving subscapularis tendon tear.
Gonadal Status and Sexual Function at Long-Term Follow-up after Allogeneic Stem Cell Transplantation in Adult Patients with Sickle Cell Disease.

OBJECTIVES Patients with adult sickle cell disease and severe sequelae are treated with nonmyeloablative allogeneic hematopoietic stem cell transplant. So far, data on gonadal effects are lacking for older cured patients. We assessed the gonadal reserve and sexual function of patients cured of sickle cell disease with transplant and with anti-T-lymphocyte globulin and posttransplant cyclophosphamide-containing regimen within the context of the Baskent Organ Damage Mitigation and Medical Care Development Program. MATERIALS AND METHODS All adult patients (≥18 years) with sickle cell disease who underwent peripheral stem cell transplant from September 2013 to July 2019 and were graft-versus-host disease free for 2 years and not immunosuppressed were invited to participate in this prospective observational study. Of 61 eligible patients, 43 participants (~10% from international registries) were included (median age at transplant was 29 years; range, 18-45 years). Gonadal status, risk of gonadal damage posttransplant, conception, and sexual function posttransplant were evaluated. RESULTS Allogeneic hematopoietic stem cell transplant was associated with increased risk of secondary amenorrhea (odds ratio of 93; 95% CI, 4.94-17.50; P = .002) and ovarian insufficiency (odds ratio of 37.8; 95% CI, 2.03 to -700.94; P = .014) but not with female sexual dysfunction. Secondary ovarian insufficiency developed in all women posttransplant. Transplant was associated with significant risk of azoospermia (odds ratio of 4.35; 95% CI, 1.02-18.45; P = .017). Moderate-to-severe erectile dysfunction developed in 2 men (10%). Among female participants, 1 had spontaneous conception that ended in miscarriage and 1 had term delivery after in vitro fertilization. Among male participants, 1 had a child by in vitro fertilization and 1 experienced spontaneous conception. CONCLUSIONS Although spontaneous conception was shown in our patient group, gonadal damage was evident at >2 years posttransplant. This risk was associated with age in female patients. Better fertility preservation measures should be incorporated into medical care development programs.
Acute caffeine supplementation and live match-play performance in team-sports: A systematic review (2000–2021)

ABSTRACT Caffeine is a psycho-active stimulant that can improve physical and cognitive performance. We systematically reviewed the evidence on the effects of acute caffeine ingestion on physiological parameters, physical and technical-skill performance during high-performance team-sport match-play. Following PRISMA guidelines, studies were identified using scientific databases (PubMed, Web-of-Science, Scopus, and SPORTDiscus) in February 2021. Of 281 results, 13 studies met inclusion, totalling 213 participants. Included studies adopted the randomised double-blinded cross-over design, involving caffeine and control conditions. In studies reporting physiological variables, responses to caffeine included higher peak (n=6/ 8 [n/ total studies measuring the variable]) and mean (n=7/ 9) heart rates, increased blood glucose (n=2/ 2) and lactate (n=2/ 2) concentrations. Improvements in physical performance were widely documented with caffeine, including greater distance coverage (n=7/ 7), high-speed distance coverage (n=5/ 7) and impact frequencies (n=6/ 8). From three studies that assessed technical-skills, it appears caffeine may benefit gross-skill performance, but have no effect, or negatively confound finer technical-skill outcomes. There is compelling evidence that ingesting moderate caffeine doses (~3 to 6 mg·kg−1) ~60 minutes before exercise may improve physical performance in team-sports, whereas evidence is presently too scarce to draw confident conclusions regarding sport-specific skill performance.
Differences between pediatric and adult atopic dermatitis

Atopic dermatitis (AD) is a common disease with a broad spectrum of clinical manifestations. AD can manifest differently in adults than children. Core AD features are similar between children and adults overall, including lesions affecting flexural areas, presence of atopy, and xerosis. Adults have more signs of chronic disease, higher prevalence and different patterns of hand eczema, and a stronger relationship of disease activity with emotional factors, whereas children with AD have more exudative lesions, perifollicular accentuation, pityriasis alba, Dennie–Morgan folds, and seborrheic dermatitis‐like presentation. These differences may be due in part to pathophysiologic differences in AD in children compared with adults. Atopic diseases commonly co‐occur with AD, although most do not temporally have the “atopic march. ” Further research is warranted to better understand the differential roles of immune dysregulation, epidermal‐barrier disruption, and dysbiosis between children and adults and determine whether such differences translate into differences in therapeutic efficacy.
Aging related impairment of brain microvascular bioenergetics involves oxidative phosphorylation and glycolytic pathways

Mitochondrial and glycolytic energy pathways regulate the vascular functions. Aging impairs the cerebrovascular function and increases the risk of stroke and cognitive dysfunction. The goal of our study is to characterize the impact of aging on brain microvascular energetics. We measured the oxygen consumption and extracellular acidification rates of freshly isolated brain microvessels (BMVs) from young (2–4 months) and aged (20–22 months) C57Bl/6 male mice. Cellular ATP production in BMVs was predominantly dependent on oxidative phosphorylation (OXPHOS) with glucose as the preferred energy substrate. Aged BMVs exhibit lower ATP production rate with diminished OXPHOS and glycolytic rate accompanied by increased utilization of glutamine. Impairments of glycolysis displayed by aged BMVs included reduced compensatory glycolysis whereas impairments of mitochondrial respiration involved reduction of spare respiratory capacity and proton leak. Aged BMVs showed reduced levels of key glycolysis proteins including glucose transporter 1 and 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 but normal lactate dehydrogenase activity. Mitochondrial protein levels were mostly unchanged whereas citrate synthase activity was reduced, and glutamate dehydrogenase was increased in aged BMVs. Thus, for the first time, we identified the dominant role of mitochondria in bioenergetics of BMVs and the alterations of the energy pathways that make the aged BMVs vulnerable to injury.
On Distinctive Image Captioning via Comparing and Reweighting

Recent image captioning models are achieving impressive results based on popular metrics, i.e., BLEU, CIDEr, and SPICE. However, focusing on the most popular metrics that only consider the overlap between the generated captions and human annotation could result in using common words and phrases, which lacks distinctiveness, i.e., many similar images have the same caption. In this paper, we aim to improve the distinctiveness of image captions via comparing and reweighting with a set of similar images. First, we propose a distinctiveness metric—between-set CIDEr (CIDErBtw) to evaluate the distinctiveness of a caption with respect to those of similar images. Our metric reveals that the human annotations of each image in the MSCOCO dataset are not equivalent based on distinctiveness; however, previous works normally treat the human annotations equally during training, which could be a reason for generating less distinctive captions. In contrast, we reweight each ground-truth caption according to its distinctiveness during training. We further integrate a long-tailed weight strategy to highlight the rare words that contain more information, and captions from the similar image set are sampled as negative examples to encourage the generated sentence to be unique. Finally, extensive experiments are conducted, showing that our proposed approach significantly improves both distinctiveness (as measured by CIDErBtw and retrieval metrics) and accuracy (e.g., as measured by CIDEr) for a wide variety of image captioning baselines. These results are further confirmed through a user study.
CosmoVis: An Interactive Visual Analysis Tool for Exploring Hydrodynamic Cosmological Simulations

We introduce CosmoVis, an open source web-based visualization tool for the interactive analysis of massive hydrodynamic cosmological simulation data. CosmoVis was designed in close collaboration with astrophysicists to enable researchers and citizen scientists to share and explore these datasets, and to use them to investigate a range of scientific questions. CosmoVis visualizes many key gas, dark matter, and stellar attributes extracted from the source simulations, which typically consist of complex data structures multiple terabytes in size, often requiring extensive data wrangling. CosmoVis introduces a range of features to facilitate real-time analysis of these simulations, including the use of “virtual skewers,” simulated analogues of absorption line spectroscopy that act as spectral probes piercing the volume of gaseous cosmic medium. We explain how such synthetic spectra can be used to gain insight into the source datasets and to make functional comparisons with observational data. Furthermore, we identify the main analysis tasks that CosmoVis enables and present implementation details of the software interface and the client-server architecture. We conclude by providing details of three contemporary scientific use cases that were conducted by domain experts using the software and by documenting expert feedback from astrophysicists at different career levels.
