Cortisol level dysregulation and its prevalence—Is it nature's alarm clock?

This review examines the stress hormone cortisol which plays an important role in regulating and supporting different bodily functions. Disruption in cortisol production has an impact on health and this review looks at a wide range of papers where cortisol has been indicated as a factor in numerous chronic conditions—especially those which are classed as “noncommunicable diseases” (NCDs). Timely detection, screening, and treatment for NCDs are vital to address the growing problem of NCDs worldwide—this would have health and socioeconomic benefits. Interestingly, many of the papers highlight the pro‐inflammatory consequences of cortisol dysregulation and its deleterious effects on the body. This is particularly relevant given the recent findings concerning COVID‐19 where pro‐inflammatory cytokines have been implicated in severe inflammation.
Dense KNN Polycrystals Doped by Er2O3 Obtained by Hot Pressing with Hexagonal Boron Nitride Protective Layer

Analysis of dense Potassium Sodium Niobate (KNN) ceramic obtained by hot pressing (HP) method at 1100 °C are presented in this paper. The synthesis of KNN-based piezoelectrics meets the following challenges—low density of material, uncontrolled K/Na ratio, multiphase composition and formation of different KNN structures. The classical hot pressing approach results in contamination by carbon originating from graphite molds. The proposed hexagonal Boron Carbide (h-BN) layer between green sample and graphite mold could protect samples from carbon contamination. Additionally, the presence of h-BN may decrease the formation of oxygen vacancies, which allows us to maintain the semiconductor features of the KNN structure. Remaining issues were addressed with the addition of excess Na and Er2O3 doping. The results showed that excess Na addition allowed us to compensate evaporation of sodium during the synthesis and sintering. Er2O3 was added as sintering aid to limit abnormal grain growth caused by h–BN addition. The modification of amount of Na and Er2O3 addition resulted in high purity KNN samples with tetragonal structure and apparent density higher than 97%. Finally, piezoelectric features of prepared dense samples were measured and presented.
Galectin-3-binding protein is a novel predictor of venous thromboembolism in systemic lupus erythematosus.

OBJECTIVES Venous (VTE) and arterial (AT) thrombosis in systemic lupus erythematosus (SLE) are poorly explained and difficult to predict. Leptin and tumour necrosis factor-like weak inducer of apoptosis (TWEAK) have been linked to subclinical atherosclerosis and galectin-3-binding protein (G3BP) to type I interferon activation and a pro-thrombotic environment. Thus, we explore serum G3BP, interferon gamma-induced protein 10 (IP-10), soluble CD163 (sCD163), TWEAK and leptin as predictors of VTE and AT, damage accrual, and all-cause mortality during follow-up in a Swedish SLE cohort. METHODS Baseline data were available from 162 SLE patients. VTE (deep vein thrombosis and/or pulmonary embolism), AT (myocardial infarction and/or stroke), damage accrual, and survival data were the main study outcomes and available at follow-up (median of five years). Baseline serum G3BP, IP-10, sCD163, TWEAK and leptin were measured and analysed by univariable and multivariable methods for association to the study outcomes. RESULTS During the follow-up, 10 (6%) VTE and 13 (8%) AT events occurred. The SLICC/ACR Damage Index increased in 78 (48%) patients, and 19 (12%) patients died. In the univariable regression analysis G3BP levels were significantly associated with an increased risk of VTE (hazard ratio (HR) 1.11, 95% confidence interval (CI): 1.01-1.22, p=0.03). This persisted in the adjusted multivariable analyses (HR 1.18, 95% CI: 1.05-1.33, p=0.007). The other biomarkers were not associated with AT/VTE, damage accrual, or all-cause mortality. CONCLUSIONS Our study identifies serum G3BP as a novel predictor of VTE in SLE. Further studies are needed to understand the role of G3BP in VTE and translate this into clinical practice.
Short lingual frenum in infants, children and adolescents. Part 1: Breastfeeding and gastroesophageal reflux disease improvement after tethered oral tissues release.

AIM This study aimed to determine the impact of laser surgical tongue-tie, lip-tie, buccal tie release on breastfeeding and Gastroesophageal Reflux Disease (GERD) in a prospective cohort study conducted from June 2019 to June 2020 in a private general dental practice. MATERIALS AND METHODS Preoperative, one-week and one-month postoperative surveys were completed, consisting of Visual Analogue Scale (VAS) for nipple pain severity, Breastfeeding Self-Efficacy Scale Short Form (BSES-SF), and the Revised Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R). All study participants were breastfeeding dyads (0-12 weeks of age) with untreated ankyloglossia and/or tethered maxillary/buccal frena. The laser surgery was completed using 2 different near- infrared diode lasers with 300µm diameter fibre: a 980 nm wavelength diode laser (Lasotronix Smart Pro, Piaseczno Poland) was used at 4.0 W, gated with 100 µs t/on and 100 µs t/off, and a 1470 nm wavelength diode laser (Pioon S1, Wuhan Pioon Tech Co Ltd., Wuhan, China), used at 3.5W, gated with 50 ms t/on and 50 ms t/off. RESULTS Statistically significant improvement was noted in VAS, I-GERQ-R and BSES-SF comparing preoperative scores to both one-week and one-month scores. The study had 132 breastfeeding dyads enrolled. Posterior tongue-tie was noted in 71% of this cohort. CONCLUSION This study confirms the need for functional assessment of tongue and lip movement for this significantly affected cohort. Laser surgical release (frenotomy) of tongue-tie, lip-tie, buccal-tie resulted in significant improvement in breastfeeding outcomes. These improvements (VAS, I-GERQ-R and BSES-SF) in breastfeeding outcomes were found for cohorts of the classically recognised anterior tongue-tie and the less obvious (without functional assessment) submucosal tongue-tie were found.
Clinicopathologic Associations in a Large International Cohort of Patients With Giant Cell Arteritis

In addition to aiding in diagnosis, histopathologic findings from temporal artery biopsy (TAB) specimens in giant cell arteritis (GCA) may be valuable for their associations with clinical features of the disease. This study was undertaken to compare histopathologic findings on TAB with biopsy interpretation and demographic, clinical, and imaging features at time of diagnosis.
Whistleblowing against doping in sport: A cross-national study on the effects of motivation and sportspersonship orientations on whistleblowing intentions

ABSTRACT Whistleblowing against anti-doping rule violations and related misconduct has been recognized as an important deterrent of doping behaviour in competitive sport. However, research on whistleblowing against doping is scarce and the available studies have focused on small samples using qualitative and inductive approaches. The present study used quantitative methods to assess, for the first time, the association between self-determined motivation, achievement goals, sportspersonship orientations and intentions to engage in whistleblowing against doping misconduct. A total of 992 competitive athletes from Greece (n = 480) and Russia (n = 512) completed structured measures of self-determination, achievement goals, sportspersonship orientation beliefs, and intentions to report doping misconduct. Latent profile analysis classified athletes into clusters consistent with the theoretical predictions. One-way analyses of variance further showed consistently across countries that autonomous motivated athletes reported higher intentions to whistleblow, and athletes with higher scores in achievement goals and sportspersonship orientations had significantly higher scores in whistleblowing intentions, compared to those with lower scores in these characteristics in both countries. This is the first study to demonstrate the association between motivational regulations, achievement goals, sportspersonship beliefs, and whistleblowing intentions. The theoretical and policy implications of our study are discussed.
Prostacyclin analog beraprost sodium efficacy in primary glomerular disease or nephrosclerosis: Analysis of the Japanese subgroup in CASSIOPEIR study

We conducted a multicenter, randomized, double‐blind, placebo‐controlled, phase IIb/III study (CASSIOPEIR) using a renal composite endpoint (i.e., doubling of SCr or end‐stage renal disease) in seven Asian countries/region. CASSIOPEIR compared TRK‐100STP (120 μg and 240 μg) with placebo in patients with non‐diabetic CKD patients with primary glomerular disease or nephrosclerosis (n = 892). However, the superiority of TRK‐100STP over placebo was not observed. A prior phase II study on which the Phase IIb/III study design was based included only Japanese patients. We therefore evaluated TRK‐100STP efficacy and safety in a subgroup of Japanese patients using the CASSIOPEIR dataset. As the timing of treatment initiation is important in CKD, we conducted additional subgroup analyses based on the baseline serum creatinine (SCr) and eGFR. ITT analysis was performed in a Japanese subgroup (n = 339) in which the primary endpoint was the first occurrence of renal composite endpoint. Significant differences were observed for TRK‐100STP 240 μg vs. placebo (P = 0.0493; HR 0.69 [95% CI: 0.47, 1.00]), but no significant difference was observed between TRK‐100 120 μg and placebo (P = 0.3523; HR 0.85). More prominent improvement was observed with TRK‐100STP 240 μg vs. placebo for baseline SCr < 3.0 mg/dL (P = 0.0031; HR 0.43); SCr < 3.5 mg/dL (P = 0.0237, HR 0.59); and eGFR ≥ 10 mL/min/1.73 m2 (P = 0.0339, HR0.67), respectively. No significant changes in urinary albumin/creatinine ratio and blood pressure were observed. TRK‐100STP was generally well tolerated and most adverse drug reactions were mild or moderate in severity. In conclusion, in the Japanese subgroup of CASSIOPEIR, TRK‐100STP 240 μg/day significantly improved the renal composite endpoint compared with placebo, with greater efficacy in subjects with SCr < 3.5 or eGFR ≥ 10 mL/min/1.73 m2.
Association between mortality and cytomegalovirus reactivation during remission induction therapy in patients with rheumatic diseases.

OBJECTIVES To elucidate the characteristics of patients with rheumatic diseases with cytomegalovirus (CMV) reactivation. METHODS In our study, we consecutively reviewed patients with rheumatic diseases who received remission induction therapy in our institution from January 2012 to March 2016 and enrolled the patients who were evaluated about CMV infection. CMV reactivation was characterised by the detection of polymorphonuclear leukocytes with CMV pp65. The characteristics and clinical courses of the patients with CMV reactivation were compared to those without CMV. RESULTS We observed CMV reactivation in 71 (39.7%, CMV-positive group) out of 179 patients. Age (odds ratio [OR] 1.023, 95% confidence interval [CI] 1.002-1.044, p=0.03), lymphocyte counts (OR 0.999, 95% CI 0.999-1.000, p=0.03), and initial prednisolone dose (OR 18.596, 95% CI 2.399-144.157, p<0.01) were considered as independent relevant risk factors for CMV reactivation. Patients in the CMV-positive group showed significantly higher incidences of all infections (48%) and severe infections (31%) than those in the CMV-negative group (48% vs .31%, p=0.037; 31% vs. 6%, p<0.001, respectively). Higher mortality was observed in the CMV-positive group than in the CMV-negative group (14.1% vs. 1.9%). The lymphocyte counts were more relevant to CMV infection and mortality than were the serum IgG levels. CONCLUSIONS Our study revealed that CMV reactivation occurred in one third of all patients with rheumatic diseases who were undergoing intensive remission induction therapy, and it was found to be relevant to other severe infections and infection-related deaths.
Concentric and eccentric inertia–velocity and inertia–power relationships in the flywheel squat

ABSTRACT The aim of this study was to evaluate the effects of varying flywheel inertia on velocity and power during flywheel squats. Fifteen healthy physically active males performed 6 maximal effort flywheel half-squats at each of 0.029, 0.061, 0.089 and 0.121 kg·m2, with velocity recorded via 3D motion capture and power recorded via inbuilt transducer. Peak concentric velocity (χ2 = 37.9; p < 0.001), peak eccentric velocity (χ2 = 24.9; p < 0.001), mean concentric velocity (F(3) = 52.7; p < 0.001) and mean eccentric velocity (χ2 = 16.8; p < 0.001) all tended to decrease with increases in flywheel inertia, whereas the ratio of peak eccentric to peak concentric power (F(3) = 4.26; p = 0.010) tended to increase. Flywheel inertia had no significant effect on peak concentric or eccentric power, or the ratio of eccentric to concentric peak or mean velocities. The best fit subject-specific inertia–velocity relationships were reported for peak concentric velocity (median linear R2 = 0.95, median logarithmic R2 = 0.97). The results suggest that velocity, rather than power, should be used to prescribe and monitor flywheel squat exercise intensities, and that individualized linear relationships between inertia and peak concentric velocity can be used for this purpose.
Part 2: Disease of the Heart and Liver: A Relationship That Cuts Both Ways

Diseases known to affect both the heart and liver include a variety of infectious, autoimmune, and metabolic disorders, as well as toxins: most commonly alcohol. As damage to both the heart and liver progresses, transplantation is a reasonable therapeutic option. Heart failure patients with underlying congestive hepatopathy receiving cardiac transplant have demonstrated improved liver enzyme levels posttransplant. Patients with severe end-stage liver disease requiring a liver transplant must undergo careful preoperative evaluation as surgical stress exposes the myocardium to high levels of catecholamines. Clinicians must consider both cardiac and hepatic complications when evaluating heart failure, cirrhosis, and nonalcoholic fatty liver disease. In Part 2 of this review, we discuss new noninvasive techniques for assessing liver fibrosis in the preoperative stage. Both serum and radiologic studies, such as transient elastography, have begun to take the place of liver biopsy due to their decreased morbidity. Last, we explore the current research examining the benefit of combined heart-liver transplant, although more longitudinal outcome studies are needed.
Muscle Strength Does Not Adapt From a Second to Third Bout of Eccentric Contractions: A Systematic Review and Meta-Analysis of the Repeated Bout Effect.

ABSTRACT Lindsay, A, Abbott, G, Ingalls, CP, and Baumann, CW. Muscle strength does not adapt from a second to third bout of eccentric contractions: A systematic review and meta-analysis of the repeated bout effect. J Strength Cond Res XX(X): 000-000, 2020-The greatest muscle strength adaptations to repeated bouts of eccentric contractions (ECC) occur after the initial injury, with little to no change in subsequent bouts. However, because of the disparity in injury models, it is unknown whether three or more bouts provide further adaptation. Therefore, we performed a systematic review of the literature to evaluate whether a third bout of skeletal muscle ECC impacts immediate strength loss and rate of strength recovery compared with a second bout. A search of the literature in Web of Science, SCOPUS, Medline, and the American College of Sports Medicine database was conducted between May and September 2019 using the keywords eccentric contraction or lengthening contraction and muscle and repeated or multiple, and bout. Eleven studies with 12 experimental groups, using 72 human subjects, 48 mice, and 11 rabbits, met the inclusion criteria. A meta-analysis using a random effects model and effect sizes (ESs; Hedges' g) calculated from the standardized mean differences was completed. Calculated ESs for immediate strength loss provided no evidence that a third bout of ECC results in greater loss of strength compared with a second bout (ES = -0.12, 95% confidence interval [CI] = -0.41 to 0.17). Furthermore, the rate of strength recovery was not different between a second and third bout (ES = -0.15, 95% CI = -1.01 to 0.70). These results indicate a third bout of skeletal muscle ECC does not improve indices of strength loss or rate of strength recovery compared with a second bout. Therefore, coaches and athletes should expect some level of persistent weakness after each of their initial training sessions involving ECC, and the faster recovery of strength deficits in the second bout documented by previous research is not different from a third bout.
Altitude and COVID‐19: Friend or foe? A narrative review

Recent reports suggest that high‐altitude residence may be beneficial in the novel coronavirus disease (COVID‐19) implicating that traveling to high places or using hypoxic conditioning thus could be favorable as well. Physiological high‐altitude characteristics and symptoms of altitude illnesses furthermore seem similar to several pathologies associated with COVID‐19. As a consequence, high altitude and hypoxia research and related clinical practices are discussed for potential applications in COVID‐19 prevention and treatment. We summarize the currently available evidence on the relationship between altitude/hypoxia conditions and COVID‐19 epidemiology and pathophysiology. The potential for treatment strategies used for altitude illnesses is evaluated. Symptomatic overlaps in the pathophysiology of COVID‐19 induced ARDS and high altitude illnesses (i.e., hypoxemia, dyspnea…) have been reported but are also common to other pathologies (i.e., heart failure, pulmonary embolism, COPD…). Most treatments of altitude illnesses have limited value and may even be detrimental in COVID‐19. Some may be efficient, potentially the corticosteroid dexamethasone. Physiological adaptations to altitude/hypoxia can exert diverse effects, depending on the constitution of the target individual and the hypoxic dose. In healthy individuals, they may optimize oxygen supply and increase mitochondrial, antioxidant, and immune system function. It is highly debated if these physiological responses to hypoxia overlap in many instances with SARS‐CoV‐2 infection and may exert preventive effects under very specific conditions. The temporal overlap of SARS‐CoV‐2 infection and exposure to altitude/hypoxia may be detrimental. No evidence‐based knowledge is presently available on whether and how altitude/hypoxia may prevent, treat or aggravate COVID‐19. The reported lower incidence and mortality of COVID‐19 in high‐altitude places remain to be confirmed. High‐altitude illnesses and COVID‐19 pathologies exhibit clear pathophysiological differences. While potentially effective as a prophylactic measure, altitude/hypoxia is likely associated with elevated risks for patients with COVID‐19. Altogether, the different points discussed in this review are of possibly some relevance for individuals who aim to reach high‐altitude areas. However, due to the ever‐changing state of understanding of COVID‐19, all points discussed in this review may be out of date at the time of its publication.
Survival Rate Following Involuntary Electroconvulsive Therapy: A Population-Based Study.

OBJECTIVE Involuntary electroconvulsive therapy (ECT) can be a lifesaving intervention for patients suffering from potentially lethal conditions who are unable to give informed consent. However, its use is not widespread, probably partly because of the scarce data on hard outcomes following involuntary ECT. In Denmark, involuntary ECT is only used when patients are at imminent/potential risk of dying if not receiving ECT. Here, we aimed to estimate the 1-year survival rate after the administration of involuntary ECT as a proxy for the effectiveness of this treatment. METHODS We conducted a register-based cohort study involving (i) all patients receiving involuntary ECT in Denmark between 2008 and 2019, (ii) age- and sex-matched patients receiving voluntary ECT, and (iii) age- and sex-matched individuals from the general population. One-year survival rates were compared via mortality rate ratios. RESULTS We identified 618 patients receiving involuntary ECT, 547 patients receiving voluntary ECT, and 3080 population-based controls. The survival rate in the year after involuntary ECT was 90%. For patients receiving involuntary ECT, the 1-year mortality rate ratios were 3.1 (95% confidence interval, 1.9-5.2) and 5.8 (95% confidence interval, 4.0-8.2) compared with those receiving voluntarily ECT and to the population-based controls, respectively. Risk factors for early death among patients receiving involuntary ECT were male sex, being 70 years or older and having organic mental disorder as the treatment indication. CONCLUSIONS Treatment with involuntary ECT is associated with a high survival rate, suggesting that the intervention is effective. However, patients receiving involuntary ECT constitute a high-risk population that should be monitored closely after this treatment.
Exercise Recovery Practices of Wheelchair Court Sports Athletes.

ABSTRACT Murphy, CJ, Mason, BS, and Goosey-Tolfrey, VL. Exercise recovery practices of wheelchair court sports athletes. J Strength Cond Res XX(X): 000-000, 2020-Research that describes the recovery practices of Para-athletes around training and competition is limited. This study investigated if and why athletes in wheelchair court sports (basketball, rugby, and tennis) use recovery strategies, what type of strategies are used, and whether the period of the season influences the prevalence of use. A cross-sectional questionnaire was developed to acquire data pertaining to individual characteristics, recovery habits, reasons for use/nonuse, the use of specific recovery strategies, and lifestyle habits. One hundred forty-four athletes (92 = international and 52 = national/club) completed the questionnaire online. In total, 85% (n = 122) of athletes reported using at least one type of recovery strategy, yet most specific types of recovery strategies were not popular (<34% of recovery strategy users). The most commonly used type of recovery strategy was stretching (n = 117), whereas both stretching and heat-related recovery were the most highly rated types of recovery strategies (μ = 4.2/5). The 3 most prevalent reasons for use across all strategies were "reduces muscle soreness," "reduces muscle tightness," and "reduces muscle spasms. " The prevalence of sleep complaints was apparent with 38% (n = 55) of respondents reporting difficulties sleeping. This study highlights that although the frequent use of well-known recovery practices is positive, the lack of diversity in strategies implemented may have implications due to the specific requirements of exercise recovery. Therefore, strength and conditioning professionals should educate wheelchair athletes further around this area and increase the range of recovery-specific and impairment-specific strategies used.
Acidic Gases Solubility in Bis(2-Ethylhexyl) Sulfosuccinate Based Ionic Liquids Using the Predictive Thermodynamic Model

To properly design ionic liquids (ILs) adopted for gases separation uses, a knowledge of ILs thermodynamic properties as well their solubilities with the gases is essential. In the present article, solubilities of CO2 and H2S in bis(2-Ethylhexyl)sulfosuccinate based ILs were predicted using the conductor like screening model for real solvents COSMO-RS. According to COSMO-RS calculations, the influence of the cation change was extensively analyzed. The obtained data are used for the prediction of adequate solvent candidates. Moreover, to understand the intrinsic behavior of gases solubility the free volume of the chosen ILs and their molecular interactions with respectively CO2 and H2S were computed. The results suggest that hydrogen bonding interactions in ILs and between ILs and the gases have a pivotal influence on the solubility.
