Educational Needs for Coaching Judo in Older Adults: The EdJCO Focus Groups

Judo coaches are urged to develop specific competencies and skills for addressing the special needs of older practitioners. Thus, the purpose of this study was to investigate the experts’ opinions on judo training in late adulthood to develop sound educational programs for coaches of older judo practitioners. Overall, eighty-eight experts from an international consortium of judo and educational partners participated in national focus groups. During the focus groups, experts discussed five themes and generated statements pertinent to educate coaches to support older judo practitioners (e.g., benefits; necessary knowledge; risks; training groups definition; tools; and tests for monitoring training plans). The initial list of 262 statements was synthesized, validated, analyzed, and organized into a final list of 55 statements and six macro-areas: aging process (n = 10); safety and first aid (n = 6); physiology and fitness (n = 12); psychology and mental health (n = 11); organization and environment (n = 5); adapted judo teaching and training (n = 11). The present international eminence-based study, harmonizing diverse intercultural perspectives, highlighted the specific needs of older judo practitioners. The results of this study will contribute to the structure of a sound educational program for coaches of older judo practitioners to enhance the quality of older adults’ sports experiences by linking safety, enjoyment, social interactions, and learning principles.
A study of clinico-mycological profile and treatment of primary otomycosis

Background: Otomycosis is a superficial mycotic infection of the external auditory canal. Clinical presentation, along with otoscopic findings, is sufficient to make the diagnosis in most of the cases. Treatment includes aural cleaning followed by the instillation of anti-fungal ear drops. In the recent years, there has been an increasing trend of antifungal resistance for the commonly used antifungals such as fluconazole and clotrimazole. Drug sensitivity patterns have also shown variability from one region to another. Aims and Objectives: To evaluate the clinico-mycological profile along with antifungal susceptibility pattern and treatment outcome of primary otomycosis. Materials and Methods: A total of 230 clinically diagnosed patients of primary otomycosis were included in this prospective study. Microbiological causes were evaluated by KOH wet mount and culture of samples collected from external auditory meatus using sterile swabs. Fungal culture was done on Sabouraud dextrose agar with chloramphenicol at 25°C and 37°C. Anti-fungal susceptibility test was done by disk diffusion method using medium Muller-Hilton agar with glucose and methylene blue. All the patients were treated with the removal of fungal debris with topical clotrimazole instillation and were followed up after 7 days. Non-responders were treated with topical itraconazole. Results: Male-to-female ratio in study participants was 1:1.3. The most frequently observed risk factor was the instillation of oil in the ear (20%). Ear itching was the commonest symptom (70.9%). Positive fungal growth was seen in 203 (88.3%) cases. Aspergillus was present in 185 (91.1%) cases, followed by Candida in 18 (8.9%) cases. Voriconazole had the highest sensitivity followed by itraconazole. 167 (83.3%) patients responded to primary treatment (topical Clotrimazole), 36 (16.7%) patients were non-responders. Conclusion: All the clinically suspected patients should be evaluated for fungal positivity, which may further guide in the selection of appropriate anti-fungal agents. Awareness regarding the predisposing factors for otomycosis in the general population may result in a significant drop in the incidence of otomycosis.

The Association between Physical Activity and Anxiety in Aging: A Comparative Analysis

(1) Background: As the worldwide aging population is growing, there is a need to embrace the role of physical activity in the anxiety of older people. Objectives: To analyze anxiety in older people practitioners and non-practitioners of physical activity; (2) Methods: ample composed of 690 older people of both genders, unselected volunteers, residing in Brazil, present (as participants or observers) in selected street races in the state of Rio de Janeiro, Brazil, between 30 October 2019, and 12 March 2020. An instrument composed of the sociodemographic questionnaire and questions from the Beck Anxiety Inventory, BAI, and the Physical Activity Inventory for older people, Baecke-Old. Design: Ex-post-facto observational analytical descriptive research; (3) Results: The average age of the sample was in the range of 65 to 69y, 74% female, 94% completed high school, 69% living with the family, 84% practicing physical activity. Anxiety levels were 26% (without), 35% (mild), 21% (moderate), and 18% (severe). The comparison of anxiety showed a difference between the groups of active and sedentary elderly. Logistic regression analysis considering anxiety (yes or no; dichotomous variable) and physical activity (yes or no; dichotomous variable) and Odds Ratio were performed to identify possible influences of the independent variables PA, gender, marital status, and education on anxiety. Only physical activity was associated with anxiety. (4) Conclusions: The sample data of this research point to the conclusion that physical activity influences anxiety levels with 98% certainty, and it is suggested that it be enriched in the future with different studies with different designs. The older people practitioners of physical activity with a high level of education presented as 26% without, 35% mild, 21% moderate, and 18% severe anxiety. More active individuals are less likely to develop anxiety.
Immunogenicity of a freeze-dried combined vaccine against Rift Valley fever and bovine ephemeral fever in cattle

Background: The target of vaccination is to encourage a strong, covering and long-lasting immune response against antigens. For achieving these objectives; effective adjuvant and new vaccine strategies are demanded to make the vaccine sufficiently immunogenic to instigate a powerful immune response Aim: This study was completed for elaboration and evaluation of freeze-dried combined vaccine against both Rift Valley fever (RVF) and bovine ephemeral fever (BEF) viruses using different stabilizers. Methods: Three formulae were prepared from such vaccine including: formula (1): stabilized with a mixture of 5% Lactalbumin Hydrolysate and 2.5% sucrose, formula (2): stabilized with a mixture of 50% the previous stabilizer and 50% of 1% Carbopol and formula (3): stabilized with 1% Carbopol solution. Samples of the three vaccine formulae were reconstituted on the time of experimental animal vaccination using saponin diluent which acts as an adjuvant for both RVFv and BEFv and as an inactivator BEF virus. The ratio between both viruses in all vaccine formulae was 1:1. Results: All vaccine batches were proved to be free of any foreign contaminants and unharmed for experimentally vaccinated animals. Each of the three groups of calves was vaccinated S/C with 2 ml of a reconstituted vaccine formula and their immune response was evaluated using serum neutralization test. The gained results revealed that the prepared combined freeze-dried vaccine with Carbopol elicited a better humoral immune response than the other two vaccine formulae. Conclusion: It could be recommended to use Carbopol as a stabilizer for the preparation of the aimed vaccine.
Argon Plasma Treatment Effects on the Micro-Shear Bond Strength of Lithium Disilicate with Dental Resin Cements

The low bond strength of lithium disilicate (LD) ceramics to dental resin cements remains a critical issue for dental applications because it leads to frequent replacement and causes tooth tissue destruction and consumption. The objective of this study was to examine the effects of atmospheric non-thermal argon plasma (NTP) treatment on LD to improve its micro-shear bond strength (μSBS) with dental resin cements because LD mostly experiences shear stress for its commonly used dental applications as crowns or veneers. Argon plasma treatment was performed on hydrofluoric (HF) acid-etched LD surfaces, and then commercial resin cements were subsequently applied to the treated LD surfaces. The plasma treatment significantly reduced the water contact angle of the LD surface to less than 10° without changing the surface morphology. The μSBS test was performed with cement-bonded LD samples after 24 h and 30 days, as well as after 1000 cycles of thermal cycling. The test results show that, as compared with the untreated controls, 300 s of plasma treatment significantly improved the LD-resin cement bond strength by 59.1%. After 30 days of storage in DI water and 1000 cycles of thermal cycling, the plasma-treated LD samples show 84.2% and 44.8% higher bond strengths as compared to the control samples, respectively. The plasma treatment effect on LD surfaces diminished rapidly as the bond strength decreased to 25.5 MPa after aging in the air for 1 day prior to primer and cement application, suggesting that primers should be applied to the LD surfaces immediately after the plasma treatment. These results demonstrate that, when applied with caution, plasma treatment can activate LD surfaces and significantly improve the SBS of LD with dental resin cements in both short-term and long-term periods.
Solvability of coupled FBSDEs with diagonally quadratic generators

We study the well-posedness for multi-dimensional and coupled systems of forward–backward SDEs when the generator can be separated into a quadratic and a subquadratic part. We obtain the existence and uniqueness of the solution on a small time interval. Moreover, the continuity and differentiability with respect to the initial value are presented.
Magnetic cloud fit by uniform-twist toroidal flux ropes

Context. Detailed studies of magnetic cloud observations in the solar wind in recent years indicate that magnetic clouds are interplanetary flux ropes with a low twist. Commonly, their magnetic fields are fit by the axially symmetric linear force-free field in a cylinder (Lundquist field), which in contrast has a strong and increasing twist toward the boundary of the flux rope. Therefore another field, the axially symmetric uniform-twist force-free field in a cylinder (Gold-Hoyle field) has become employed to analyze magnetic clouds. Aims. Magnetic clouds are bent, and for some observations, a toroidal rather than a cylindrical flux rope is needed for a local approximation of the cloud fields. We therefore try to derive an axially symmetric uniform-twist force-free field in a toroid, either exactly, or approximately, and to compare it with observations. Methods. Equations following from the conditions of solenoidality and force-freeness in toroidally curved cylindrical coordinates were solved analytically. The magnetic field and velocity observations of a magnetic cloud were compared with solutions obtained using a nonlinear least-squares method. Results. Three solutions of (nearly) uniform-twist magnetic fields in a toroid were obtained. All are exactly solenoidal, and in the limit of high aspect ratios, they tend to the Gold-Hoyle field. The first solution has an exactly uniform twist, the other two solutions have a nearly uniform twist and approximate force-free fields. The analysis of a magnetic cloud observation showed that these fields may fit the observed field equally well as the already known approximately linear force-free (Miller-Turner) field, but it also revealed that the geometric parameters of the toroid might not be reliably determined from fits, when (nearly) uniform-twist model fields are used. Sets of parameters largely differing in the size of the toroid and its aspect ratio yield fits of a comparable quality.
Internet-Based Recruitment and Retention of Young Adults With Type 1 Diabetes: Cross-Sectional Study

Background Multiple research strategies are required to recruit and engage a representative cohort of young adults in diabetes research. In this report, we describe an approach for internet-based recruitment for a repeated-measures descriptive study. Objective The objective of this cross-sectional study was to determine whether internet-based recruitment through multiple social media platforms, a clinical research platform, and cooperation with community partnerships—College Diabetes Network and Beyond Type 1—would serve as an effective way to recruit a representative sample of young adults aged 18-25 years with type 1 diabetes (T1D). Methods We conducted a repeated-measures descriptive study. We captured enrollment rates and participant characteristics acquired from each social media platform through survey data and Facebook analytics. This study was advertised via paid postings across a combination of different social media platforms (eg, Facebook, Instagram, Twitter, and Reddit). We used quarterly application postings, quarterly newsletters, and participation in the ResearchMatch registry to identify potentially eligible participants from February 3, 2021, to June 6, 2022. Results ResearchMatch proved to be the most cost-effective strategy overall, yielding the highest gender and racial diversity compared to other internet platforms (eg, Facebook, Instagram, Twitter, and Reddit), application postings (eg, Beyond Type 1), and newsletters (eg, College Diabetes Network and a local area college). However, we propose that the combination of these approaches yielded a larger, more diverse sample compared to any individual strategy. Our recruitment cost was US $16.69 per eligible participant, with a 1.27% conversion rate and a 30% eligibility rate. Conclusions Recruiting young adults with T1D across multiple internet-based platforms was an effective strategy to yield a moderately diverse sample. Leveraging various recruitment strategies is necessary to produce a representative sample of young adults with T1D. As the internet becomes a larger forum for study recruitment, participants from underrepresented backgrounds may continue engaging in research through advertisements on the internet and other internet-based recruitment platforms.
Chronic Limb-Threatening Ischemia in Patients with Type 2 Diabetes: Revascularization Index as a Predictor for Primary Endovascular Intervention Outcome

Purpose Chronic limb-threatening ischemia in patients with diabetes is associated with a high risk of adverse outcomes. The associated co-morbidities, the heterogeneity of foot presentation and the distribution of atherosclerotic lesions led to the emergence of multiple revascularization strategies and scoring systems to improve management outcomes. This study aimed to introduce a new index, the revascularization index (RI), and to assess its predictive value for the outcomes of primary endovascular intervention in patients with type 2 diabetes presenting with chronic limb-threatening ischemia. Patients and Methods A retrospective electronic medical records review was conducted for patients with type 2 diabetes presenting with chronic limb-threatening ischemia managed at King Abdullah University Hospital by primary endovascular interventions between January 2014 and August 2019. The RI was analyzed for its predictive value for the treatment outcomes. Results A total of 187 patients were included in this study, with a major lower limb amputation rate of 19.3%. The performance of the RI was excellent in predicting secondary revascularization (AUC = 0.80, 95% CI: 0.73–0.86, p-value < 0.001), good to predict major amputation (AUC = 0.76, 95% CI: 0.67–0.85, p-value = 0.047), and poor in predicting death (AUC = 0.46, 95% CI: 0.40–0.55, p-value = 0.398). RI of <1.21 was significantly associated with a higher risk of major lower limb amputation (HR = 5.8, 95% CI: 1.25–26.97, p-value < 0.025), and RI of < 1.3 was associated with a higher risk for secondary revascularization. Conclusion The RI can be used to predict major adverse lower limb events (MALE). It might be used as a guide for the extent of endovascular interventions for diabetic chronic limb-threatening ischemia with multi-level outflow atherosclerotic disease.
Numerical and experimental analysis of a RVE condition for heterogeneous materials using BEM and thermal images

espanolEste trabajo se enfoca en el estudio numerico y experimental de los efectos de la conductividad termica en materiales heterogeneos. El analisis numerico se basa en la formulacion de Metodo de los Elementos de Contorno (MEC) basada en la tecnica de subregiones con el fin de simular un dominio bidimensional con inclusiones de material distribuidas aleatoriamente. Las condiciones de contorno fueron seleccionadas adecuadamente con el fin de obtener condiciones de conductividad termica unidireccional. La Teoria de los Campos Medios (TCM) es aplicada para determinar el elemento de volumen representativo (EVR) para los casos estudiados. Finalmente, el coeficiente de conductividad termica efectivo es obtenido a partir del EVR. Para la verificacion de los resultados numericos obtenidos es propuesto un procedimiento experimental basado en imagenes termicas. El montaje experimental replica la condicion de flujo de calor unidireccional en una placa de acero. La conductividad termica efectiva experimental es obtenida a partir del analisis de las imagenes termicas del campo de temperatura resultante en la superficie de la placa las cuales fueron tomadas con una camara infrarroja. La comparacion entre los resultados numericos y experimentales resulto en una diferencia de 3% entre los dos resultados, apuntando el buen desempeno de la metodologia propuesta. EnglishThis work focuses on the numerical and experimental study of the effective thermal conductivity in materials with heterogeneous composition. The numerical analysis relies in the Boundary Element method (BEM) formulation assisted by the sub-regions technique to simulate a two-dimensional square domain, with randomly distributed material inclusions. The boundary conditions are set to achieve a unidirectional heat flux condition. The Average Field Theory (AFT) is applied to determinate the representative volume element (RVE) condition for the studied cases. Finally, the effective heat conduction coefficient is obtained from the defined RVE’s. To verify the obtained numerical results, it is proposed an experimental procedure based on thermal images. The experimental assembly replicates the unidirectional heat flux condition over a steel plate. The experimental effective thermal conductivity is obtained from the analysis of the resultant temperature field on the surface of the plate taken by an infrared camera. The comparison between the numerical and experimental results showed a 3% difference between both results, pointing out for the successfulness of the proposed methodology.
Urinary Marinobufagenin in Patients with Non-Advanced Chronic Kidney Disease: A Cross-Sectional Study

Background and Objectives: The global prevalence of chronic kidney disease (CKD) is on the rise, posing important challenges for healthcare systems. Thus, the search for new factors potentially involved in the pathogenesis, progression and complications of early CKD remains urgent. Marinobufagenin (MBG) is a natriuretic endogenous cardiotonic steroid, and increased circulating levels of it may accelerate kidney damage. In this study, we explored the possible clinical significance of measuring urinary marinobufagenin (uMBG) in patients with non-advanced CKD. Materials and Methods: One hundred and eight adult CKD patients (mean age 71.6 ± 10 years, 70.4% male; mean eGFR 40.54 ± 17 mL/min/1.73 m2) were enrolled in this cross-sectional study. uMBG was measured together with a series of clinical, anthropometric, laboratory and instrumental analyses. Twenty-five healthy matched subjects served as controls for the uMBG measurement. Results: The uMBG values were lower in the patients with CKD as compared to those of the controls (0.37 [IQR: 0.25–0.45] vs. 0.64 [0.46–0.78] nmol/L. p = 0.004), and a significant trend in eGFR levels was noticed across the decreasing uMBG tertiles (p = 0.03). Regarding the correlation analyses, the uMBG values remained robustly associated with the eGFR in multivariate models employing either uMBG or eGFR as the dependent variable (β = 0.248; p = 0.01 and β = 0.139; p = 0.04, respectively). Besides the eGFR, the independent predictors of uMBG values in this population were the use of statins (β = −0.326; p = 0.001), the presence of diabetes (β = 0.243; p = 0.009) and urine sodium (β = 0.204; p = 0.01). Conclusions: Reduced uMBG excretion may reflect impaired renal clearance, which may contribute to the detrimental effects attributed to this hormone due to systemic accumulation. Future studies are needed to clarify the biological mechanisms placing uMBG at the crossroad of sodium intake and the presence of diabetes in CKD-suffering individuals and to verify whether a statin treatment may somewhat limit the detrimental effects of MBG in the presence of impaired renal function.
Phenotypic trait association studies in brinjal upon drought stress

Eggplant is popularly known as poor man’s vegetable. With respect to present situation of climatic challenges, fruit yield of eggplant is reduced due to drought or moisture stresses. In view of this condition, an experiment was aimed to study character association between yield and yield components in eggplant. The resultant outcome from correlation analysis computed among nine eggplant characters indicated that traits like plant height and total plant length at harvesting, fruit length and number of fruits per plant significantly correlated with fruit yield per plant. Whereas, traits like plant height and total plant length observed at harvesting stage, number of days for flower initiation, number of primary branches, fruit length and average fruit weight were significantly associated with fruit yield per plant under moisture stressed condition.
