The kringle domain of urokinase‐type plasminogen activator potentiates LPS‐induced neutrophil activation through interaction with αVβ3 integrins

Urokinase plasminogen activator (uPA) is a serine protease that catalyzes the conversion of plasminogen to plasmin. In addition, uPA has been shown to have proinflammatory properties, particularly in potentiating lipopolysaccharide (LPS)‐induced neutrophil responses. To explore the mechanisms by which uPA exerts these effects, we examined the ability of specific uPA domains to increase cytokine expression in murine and human neutrophils stimulated with LPS. Whereas the addition of intact uPA to neutrophils cultured with LPS increased mRNA and protein levels of interleukin‐1β, macrophage‐inflammatory protein‐2, and tumor necrosis factor α, deletion of the kringle domain (KD) from uPA resulted in loss of these potentiating effects. Addition of purified uPA KD to LPS‐stimulated neutrophils increased cytokine expression to a degree comparable with that produced by single‐chain uPA. Inclusion of the arginine‐glycine‐aspartic but not the arginine‐glycine‐glutamic peptide to neutrophil cultures blocked uPA kringle‐induced potentiation of proinflammatory responses, demonstrating that interactions between the KD and integrins were involved. Antibodies to αV or β3 integrins or to the combination of αVβ3 prevented uPA kringle‐induced enhancement of expression of proinflammatory cytokines and also of adhesion of neutrophils to the uPA KD. These results demonstrate that the KD of uPA, through interaction with αVβ3 integrins, potentiates neutrophil activation.
Perceived Stress Among Iranian Nursing Students in a Clinical Learning Environment: A Cross-Sectional Study

Background Nursing students experience a high level of stress in clinical settings. This study aimed to investigate the stress perceived by Iranian nursing students in the clinical learning environment and its relationship with the characteristics of students. Methods In this cross-sectional study, 430 nursing students who had passed at least 1 clinical training unit were recruited from universities in the Southeast of Iran using the census method. Data were collected by administering a demographic and researcher-made questionnaire to assess the perceived clinical stress. Demographic characteristics included age, sex, marital status, year of study, interest in the field, and previous semester average. Data were analyzed using independent t-test, ANOVA, and correlation coefficient test (α < 0.05). Results The mean score of overall stress experienced by the participants was 92.08±16.8 (out of 160), which was at a moderate level. Based on the study results, the most stress-inducing factors for students were instructors’ limited clinical competence and instructors’ inappropriate conduct. Gender (p = 0.01), fathers’ education (p = 0.01), mothers’ education (p = 0.01), interest in the field (p = 0.01), and year of study (p = 0.01) had a significant effect on the mean score of perceived clinical stress. Conclusion The results of this study showed a moderate level of stress among the students. Also, instructors’ limited clinical competence and inappropriate conduct were 2 factors that caused the highest perceived stress among nursing students more than other factors.
Stroke prevention and guideline adherent antithrombotic treatment in elderly patients with atrial fibrillation

Abstract Patients aged ≥75 years with the diagnosis of atrial fibrillation (AF) are at a higher risk of stroke and, according to recent recommendations, should receive oral anticoagulant (OAC) therapy. This study aimed to assess the recommended prophylactic antithrombotic therapy among patients with AF aged ≥ 75 years and its compliance with current guidelines. We also aimed to identify predisposing factors associated with the administration of non-vitamin K antagonist oral anticoagulants (NOACs) in elderly patients with AF. This was a retrospective, single-center observational study. Patients with AF aged ≥75 years hospitalized at a reference cardiology center from 2014 to 2017 were included in the analysis. Among the 1236 eligible patients (43.4% male; mean age, 82 years), OACs were recommended in 90.1% of cases. Of these, 59.8% of patients used NOACs and 40.2% used vitamin K antagonists. Additionally, 3.3% of patients received antiplatelet (AP) therapy and 2.5% were administered low molecular weight heparin. Only 4.5% of patients did not receive any anticoagulant treatment. The majority (89.9%) of patients received relevant prophylactic antithrombotic therapy according to current guidelines; only 1.4% were overtreated and 8.7% were undertreated. The significant predictors of NOAC therapy among patients treated with anticoagulants were non-permanent AF (odds ratio [OR] = 1.68, 95% confidence interval [CI] = 1.30–2.18, P = .0001), age-by 5 years (OR = 1.33, 95% CI = 1.16–1.52, P = .0001), and glomerular filtration rate-by 5 units (OR = 1.06, 95% CI = 1.02–1.10, P = .0066). A high percentage of AF patients aged ≥75 years receive OACs, mainly NOACs. Most patients are treated according to the current guidelines; under treatment is primarily observed in patients receiving AP therapy. Non-permanent AF, age, and preservation of renal function are significant predictors of NOAC use.
Validity and reliability of the Persian version of the Adverse Childhood Experiences Abuse Short Form

BACKGROUND AND AIM: Measuring child abuse and adverse experiences is a critical task with regard to its long-term impact on the health of individuals and communities. The purpose of this study was to validate the Persian version of the International Adverse Childhood Experiences Abuse Short Form (ACE-ASF) in Iranian society. MATERIALS AND METHODS: This cross-sectional study was conducted in Kerman, southeast of Iran, in 2019, on 494 students from Kerman University of Medical Sciences, selected by convenience sampling method. Psychometric properties of the questionnaire were examined after the forward and backward translation processes. The factor structure of the questionnaire was evaluated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The concurrent validity of the questionnaire was assessed using the childhood trauma questionnaire (CTQ). Cronbach's alpha and corrected item-total correlation were used to measure reliability. RESULTS: The mean age of participants was 24.3 ± 5.3 years. Based on EFA, two physical–emotional abuse and sexual abuse factors were obtained. The CFA fit indices well supported two extracted factors. The CFA showed acceptable factor loadings. The internal consistency coefficient of Cronbach's alpha was 0.75 for the physical–emotional abuse factor and 0.77 for the sexual abuse factor. The correlation coefficient of ACE-ASF and CTQ was r = 0.56. The reliability index of intraclass correlation coefficient was 0.73 (95% confidence interval: 0.60–0.84). CONCLUSION: The Persian version of the ACE-ASF questionnaire has acceptable psychometric properties.
Effect of digital storytelling intervention on burnout thoughts of adolescent

Abstract Background/Objective: Both athletes with and without disabilities can develop burnout symptoms. However, athletes with disabilities may face different or more challenges compared to their counterparts without disabilities. The present study aimed at ascertaining the effect of digital storytelling intervention on burnout thoughts of adolescent-athletes with disabilities. Method: This study is a randomized controlled trial involving a total of 171 adolescent-athletes with disabilities who showed a high degree of burnout symptoms. These adolescent-athletes were randomly assigned to either an intervention group (n = 85) or a waitlisted control group (n = 86). The treatment intervention for the adolescent-athletes was digital stories which were created based on the framework of rational emotive behaviour therapy (REBT). The Athlete Burnout Questionnaire was used for gathering of data at three different times (baseline, post-test and follow up). Data were analyzed using repeated measure analysis of variance at a significant level of 0.05. Results: Results showed that the digital storytelling intervention based on REBT significantly reduced burnout thoughts among disabled adolescent-athletes in the intervention group compared to athletes in the waitlisted control group as measured by the Athlete Burnout Questionnaire. Additionally, at follow-up evaluation, it was observed that the decrease in burnout scores was maintained by those athletes in the digital storytelling intervention. Conclusion: Digital storytelling intervention based on rational emotive behaviour therapy shows great potentials in addressing burnout among adolescent-athletes with disabilities.
CPAP Therapeutic Options for Obstructive Sleep Apnea

Introduction There are many options available to patients who are placed on constant positive airway pressure (CPAP) for obstructive sleep apnea. Despite the success of CPAP in correcting apnea, a significant number of patients have difficulty with the therapy. A large number of those patients who have difficulty stop therapy and are often labeled as “CPAP Failure”. Non-sleep specialists may view CPAP therapy as a singular course of treatment, but there are many ways CPAP may be ordered for a patient. Each patient experiences a unique set of options that constitute a unique order set. Methods In order to demonstrate the magnitude of the possible options, estimates of the number of unique order sets were calculated. The author chose individual order options and the number of selections possible within each option. The calculated sets included a “Generous, Limited and Minimal” number of selections for each option. Calculations were done separately for standard CPAP and for auto-adjusting CPAP. Additional calculations were performed using the number of commercially available masks in the United States. Results The maximum number of unique order sets was seen using a standard CPAP combined with commercially available masks: 49,152 unique order sets. The fewest number of unique order sets were seen with the auto-adjusting CPAP and the “Minimal” selections: 288 unique order sets. Discussion There are a large number of unique CPAP orders that a patient may experience. CPAP treatment is not a singular or simple therapy. When evaluating obstructive sleep apnea patients with histories of CPAP failure or prior difficulty with CPAP, paying close attention to the patient’s treatment experiences may help explain a significant number of those patients’ CPAP therapy problems.
Antioxidant and Scavenging Activities of Flavonoid Extract (Kolaviron) of Garcinia kola Seeds

The antioxidant and scavenging properties of kolaviron, a flavonoid extract of Garcinia kola seeds, were evaluated in a series of in vitro assays involving free radicals and reactive oxygen species. Kolaviron exhibited markedly reducing power and antioxidant activity by inhibiting the peroxidation of linoleic acid. Kolaviron exhibited 57% scavenging effect on superoxide at a concentration of 1 mg/ml and 85% scavenging effect on hydrogen peroxide at a concentration of 1.5 mg/ml. Similarly, kolaviron, at a concentration of 2 mg/ml, elicited an 89% scavenging effect on a,a-diphenyl-ß-picrylhydrazyl radical, indicating that the extract has effective activities as a hydrogen donor and as a primary antioxidant to react with lipid radicals. Kolaviron reacted with hydroxyl radical (·OH) by inhibiting deoxyribose oxidation induced by a Fenton-type reaction system (Fe 3+ + EDTA/H 2 O 2 /ascorbic acid). The second-order rate constant for the reaction with ·OH was approximately 1.1 × 10 10 M -1 sec -1. Kolaviron was effective at preventing microsomal lipid peroxidation induced by iron/ascorbate in a concentration dependent manner. The overall antioxidant activity of kolaviron on lipid peroxidation might be attributed to its properties of scavenging free radicals and active oxygen species and may relate directly to prevention of propagation of in vivo lipid peroxidation.
Chromosome numbers and karyotypes of Catasetum species (Orchidaceae)

Mitotic chromosomes of 12 species of Catasetum were assessed to contribute with the karyotypic study of the subtribe Catasetinae (Orchidaceae), expanding the knowledge of this group in terms of chromosomes and supporting its taxonomic and evolutionary analysis. The species are maintained in cultivation in the greenhouse of the Department of Plant Biology/IB/UNICAMP and in the “Orquidário Frederico Carlos Hoehne” of the Botanical Garden of São Paulo. Chromosome counts ranged from 2n = 54 to 2n = 108. Karyotypes were prepared for all species studied, in which there was a predominance of metacentric chromosomes and some submetacentric ones. The chromosome size ranged from 0.5 to 4.9 μm, the total chromosome length ranged from 34.7 to 78.7 μm and the asymmetry index TF% ranged from 21.2 to 42.3. The results obtained so far favor the taxonomy of the genus, allowing to distinguish species with very similar external morphology.
Diet of introduced largemouth bass in Korean rivers and potential interactions with native fishes

– A dietary analysis of largemouth bass (Micropterus salmoides), an exotic, piscivorous species, was conducted in large South Korean river systems (>third order streams, 31 sites). Micropterus salmoides larger than 100 mm exhibited intense piscivory on native Korean juvenile fishes, with levels of piscivory amongst the highest recorded globally, for native and introduced populations. Largemouth bass exhibited an ontogenetic shift in diet, showing a progressive increase in piscivory with size, typical of this species within its native range but unlike several studies on introduced largemouth bass in Europe and Africa. Sampling of fish communities at the same sites used for diet studies showed that native piscivores and the main food fish species of largemouth bass were significantly less abundant (P = 0.049 and 0.045, respectively) at sites where bass were present than at sites where no bass were recorded. Largemouth bass may pose a threat to the structure of fish assemblages in Korean river systems and further study of their population interactions and how to minimise their spread is needed.
Human-Cooperative Control Design of a Walking Exoskeleton for Body Weight Support

In the paper, the development, control, and preliminary evaluation of the human–robot coupled walking exoskeleton for weight-support enhancement are presented, which provides the assistance of abduction/adduction and flexion/extension for the hip joint, and the flexion/extension for knee joint of human legs during walking. The trajectory generation strategy for the walking exoskeleton utilizes the inverted pendulum approximation. Considering human in the control loop, the periodic walking trajectory and uncertainties with known periods, we propose a human-cooperative adaptive fuzzy strategy combing virtual tunnels that allows human subjects to change the movement timing of their legs and produce a physiological path. The strategy does not need human–robot coupled model, and the designed compliant virtual constraints keep the legs of the subject within the constrained tunnel around the expected path. The subjects with the assistance of supporting torques can walk effortlessly along the spatial path. The path control strategy has been verified with two healthy subjects. The recorded kinematic data demonstrated that the participants are able to achieve stable walking with larger spatio-temporal variability.
Reproduction, gamete supply and larval rearing of New Zealand turbot Colistium nudipinnis (Waite 1910) and brill Colistium guntheri (Hutton 1873): a potential new aquaculture species.

New Zealand turbot Colistium nudipinnis (Waite 1910) and brill Colistium guntheri (Hutton 1873) were studied to assess their potential for aquaculture development. The reproductive cycle of wild fish showed a long spawning season from winter to summer, during which it is possible to obtain gametes. Both species have a diurnal ovulatory cycle, and gamete collection, by stripping and fertilizing at sea, was most successful within 2–3 h before and after sunset. Male reproductive anatomy suggests that these flatfish spawn in close proximity and that pair formation is highly likely. The eggs of both species have multiple oil droplets, turbot eggs being slightly larger (0.99 mm diameter) with more droplets (18–55) than brill eggs (0.97 mm, 13–26 droplets). Hatching occurred approximately 84 h after fertilization at 14 °C. Newly hatched turbot averaged 2.2 mm in length, and brill averaged 2.1 mm. First feeding began 4 days post-hatch (DPH). During larval rearing, rotifers were replaced by Artemia nauplii at 10 DPH. Metamorphosis commenced at 12–15 DPH and was completed and the larvae settled by 45 DPH. Weaning to inert foods began at 20–22 DPH (50 mg weight) and was completed by 57 DPH. Survival of turbot was 22.8% from fertilized egg to hatching, 7.3% through incubation to 22 DPH and 2.1% through incubation to fully weaned juveniles. Weaning success for turbot from metamorphosis to 57 DPH was 31.5%.
Platelet-Rich Plasma-Derived Growth Factor vs Hyaluronic Acid Injection in the Individuals with Knee Osteoarthritis: A One Year Randomized Clinical Trial

Objective In this study, we aimed at performing a comparison between intra-articular injections of PRP-derived growth factor (PGRF) and hyaluronic acid regarding their effect on pain and patient’s function in knee osteoarthritis, as well as their safety profiles. Methods During our single-masked randomized clinical trial, the candidates with symptomatic knee osteoarthritis received two intra-articular injections of PRGF with 3 weeks apart or received three weekly injections of HA. The mean improvements from before treatment until the second, sixth, and twelfth months post-intervention in scores obtained by visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne index were our primary outcomes. Results A total of 102 candidates were finally included in the study. Patients’ mean age was 57.08±7.3 years old in the PRGF group compared to the mean age of 58.63±7.09 years old in HA patients. In the PRGF group, total WOMAC index decreased from 41.96±11.71 to 27.10±12.3 (P = 0.02), and from 39.71±10.4 to 32.41±11.8 in the HA group after 12 months (P > 0.05). Regarding the Lequesne index, pain, ADL, and global scores significantly decreased after 12 months in the PRGF group compared to the HA group (P<0.001). There was also a meaningful higher rate of satisfaction in the PRGF group compared to the HA group after 12 months of treatment (P<0.001). Conclusion Besides significantly higher satisfaction belonging to the PRGF group, there was a statistically significant improvement in VAS score and global, pain, and ADL score of Lequesne by passing 12 months from injection in PRGF compared to HA.
Therapeutic Effects of Garlic on Hepatic Steatosis in Nonalcoholic Fatty Liver Disease Patients: A Randomized Clinical Trial

Background and Aims Emerging evidence suggests that garlic (Allium sativum L.) and its bioactive components can mitigate hepatic steatosis by the modulation of hepatic lipid metabolism. We aimed to assess the efficacy of the garlic administration on hepatic steatosis in patients with NAFLD. Patients and Methods This clinical trial was conducted on adult patients with ultrasound-diagnosed NAFLD. Eligible participants were randomly assigned, with the use of the stratified blocked procedure, to receive 800 mg garlic or placebo for 15 weeks. The primary outcome was the improvement in the hepatic steatosis diagnosed by ultrasound technique after 15 weeks of intervention. Results A total of 110 patients underwent randomization, and 98 patients completed the trial. Twenty-four (51.1%) patients in the garlic group achieved improvement in the hepatic steatosis compared to eight (15.7%) patients in the placebo group with the relative risk of 5.6 (95% CI: 2.17 to 14.5; P=0.001), which remained significant after adjusting for baseline value of hepatic steatosis. There were significant reductions in weight and serum ALT, AST, FBS, Hb A1C, total cholesterol, LDL-cholesterol, and TG concentration with the garlic intake compared to placebo (P<0.05). The results were also significant after adjusting for weight change, energy intake, and physical activity. No serious adverse effects were observed with the garlic intake. Conclusion The intake of garlic powder was accompanied by a significant improvement in the hepatic steatosis and comorbidity related to this condition among subjects with NAFLD.
Expression of PD-1 and PD-L1 on Tumor-Infiltrating Lymphocytes Predicts Prognosis in Patients with Small-Cell Lung Cancer

Introduction Immune therapy has shown good results in small-cell lung cancer (SCLC), but the impact of immune microenvironment of the disease is unclear. In this work, we detected expression of programmed death 1 (PD-1), PD-ligand 1 (PD-L1), and other immune biomarkers of cancer. We also analyzed the correlations between these markers and survival in SCLC. Patients and Methods Protein expression of PD-1, PD-L1, PD-L2, CD3, CD4, CD8, and FOXP3 was analyzed in surgical tissues from 102 SCLC patients by immunohistochemistry. Results Positive expression of PD-1 on tumor-infiltrating lymphocytes (TILs) was found in 40.2% of patients; 37.3% of patients showed positive expression of PD-L1 on TILs; and 3.9% showed positive expression of PD-L1 on tumor cells. PD-L2 protein was not expressed on tumor cells or TILs. Survival analysis showed that positive expression of PD-L1 on TILs was correlated with longer relapse-free survival (RFS) (p=0.004). Positive expression of PD-1 combined with a high ratio of lymphocytes (CD3, p=0.004; CD4, p=0.011; CD8, p=0.009; FOXP3, p=0.009) was associated with significantly better RFS than negative expression of PD-1 combined with a lower ratio of lymphocytes. Positive expression of PD-L1 combined with a high ratio of lymphocytes (CD3, p<0.001; CD4, p=0.001; CD8, p=0.002; FOXP3, p=0.001) was associated with significantly better RFS than negative expression of PD-L1 combined with a lower ratio of lymphocytes. All patients’ stage were between I and III. Conclusion PD-1 and PD-L1 expression might be good prognostic factors in SCLC.
Anti-NMDA receptor encephalitis concomitant with myelin oligodendrocyte glycoprotein antibody diseases

Abstract Anti-N-methyl-d-aspartate receptor encephalitis (NMDARe) can coexist with myelin oligodendrocyte glycoprotein antibody (MOG-ab) disease. To characterize MOG-ab disease during NMDARe, we analyzed all the patients with MOG-ab disease and NMDARe from our hospital from December 2018 to December 2019 and data from a systematical review of previously published reports. Details of the patients identified were summarized and literature was reviewed. Four of thirty (14.2%) patients with anti-NMDARe had overlapping MOG-ab disease in our department. Analyze together with previously reported cases. Thirty-two NMDARe patients had overlapping MOG-ab disease. The onset age ranged from 3 to 48 years. Twenty-four patients (74%) developed abnormal behavior or cognitive dysfunction during the episodes of anti-NMDARe. None of these patients had tumors. 84% (27/32) patients received high doses of steroids as first-line immunotherapy and 28% (9/32) received mycophenolate mofetil (MMF) to prevent relapse. Twenty-six of twenty-seven (96%) had a good outcome. Steroids are the most common first-line immunotherapies in NMDARe overlapping MOG-ab disease. Most of the NMDARe patients overlapping MOG-ab disease have a good prognosis.
