Background: Vertical jump performance is a key indicator of athletic ability, however, evidence on its relationship with body weight remains inconsistent. Since jump performance depends on strength, body composition, and neuromuscular factors, it was hypothesized that vertical jump performance would not be adversely affected by body weight in athletes with average BMI. This study examined the relationship between body weight, BMI, and vertical jump performance in young basketball players. Methods: A cross-sectional study was conducted with 29 male basketball players (mean body weight 77.27 9.20 kg; BMI 22.97 0.97) who volunteered to participate. Standardized biometric assessments and vertical jump tests were administered. Pearson correlation analysis was performed to assess associations between body weight, BMI, and jump performance. Results: Moderate positive correlations were identified between body weight and vertical jump performance (r = 0.392, p < 0.05) and between BMI and vertical jump performance (r = 0.394, p < 0.05). However, low explanatory power (R) indicates limited predictive value of body weight and BMI. A strong positive correlation between body weight and BMI (r = 0.550, p < 0.01) was also observed. Conclusion: Body weight and BMI showed limited predictive ability for vertical jump performance in young basketball players. Factors such as muscular strength, fat percentage, and neuromuscular efficiency may play a more significant role in jump ability. These findings highlight the necessity of comprehensive performance assessment and individualized training strategies in athletic populations.

Some children’s “muscular-skeletal system” disorders can be seen early in newborns and babies. They are symptoms of Minimal Brain Dysfunction (MBD). These abnormalities are caused by an asphyxia of the fetus during pregnancy or delivery. This study discusses Minimal Brain Dysfunction (MBD) and Its Impact on Musculoskeletal Deformities. This study also discusses the causes, symptoms, and physiotherapy interventions of MBD. Among various disorders of the locomotor system in children and also in youth patients, there are changes connected with the functioning of the Central Nervous System. Children with MBD have also psychological changes in their behavior. In the diagnosis, it is important to inquire about the gravidity and the delivery. Early therapy is the best prophylaxis of pain syndromes and arthrosis of the feet, knees, hips, and spine in adults.

Background/Objectives: Osteoarthritis (OA) is a chronic and progressive joint disease, leading to functional limitations and significantly impairing the quality of life. Muscle weakness, reduced mobility, and compensatory biomechanical changes are common consequences, further exacerbating functional decline. The aim of this study was to assess the impact of hip osteoarthritis on muscle functionality and to evaluate the effectiveness of hip arthroplasty using the MyotonPro device to measure key biomechanical parameters, i.e., tension, stiffness, and flexibility. Methods: This cohort study included 40 patients (17 women and 23 men; mean age 64.55 ± 10.49 years) with advanced hip OA (Kellgren-Lawrence grade III-IV) undergoing hip arthroplasty. Measurements of muscle tension (F), stiffness (S), and flexibility (D) in the gluteus maximus, rectus femoris, and biceps femoris were performed at three time points: before surgery, on postoperative days 8-10, and one month after hospital discharge. Pain (VAS), balance (Tinetti scale), and functional ability (WOMAC index) were also assessed. Results: Hip arthroplasty significantly reduced pain levels (VAS: 6.38 ± 0.28 preoperatively to 1.88 ± 0.22 postoperatively, p < 0.001) and improved functional ability (WOMAC: p < 0.001). Muscle tension and stiffness of the gluteus maximus initially increased after surgery (tension: 11.57 ± 0.32 to 12.15 ± 0.38, p = 0.009), reflecting compensatory stabilization but decreased by the final evaluation. Flexibility improved significantly over time (p = 0.014). The biceps femoris muscle exhibited a significant reduction in tension one month postoperatively (p = 0.015), alongside decreased stiffness (p = 0.015) and enhanced flexibility. The rectus femoris muscle showed minor changes in biomechanical properties, with no statistically significant differences detected. Conclusions: Osteoarthritis significantly impacts muscle function, reducing the gluteus muscle tension and stiffness, which compromises joint stability and triggers compensatory activity in the rectus femoris and biceps femoris muscles. Postoperative rehabilitation is essential for improving flexibility and addressing compensatory muscle tension.

Introduction. Nursing is widely recognized as a public trust profession due to its emphasis on professionalism, ethical standards, and patient-centered care. The profession demands adherence to legal regulations and ethical norms, fostering trust through its critical role in healthcare delivery. This study aims to explore patients' perceptions of nursing as a public trust profession, focusing on key factors such as professionalism, ethical compliance, and personal attributes of nurses. Objective. The primary goal of this study was to assess patients' opinions regarding nursing as a public trust profession and identify the specific attributes and competencies that underpin this perception. Methods. The study employed a diagnostic survey method using a structured questionnaire. A total of 100 patients from a healthcare facility in the Mazovian Voivodeship participated. Statistical analyses, including descriptive statistics, chi-square tests, t-tests, ANOVA, correlation analyses, and factor analysis, were conducted using IBM SPSS 29. Results. The findings revealed that 95% of respondents identified professionalism and high engagement in care as crucial factors for trust. Empathy and compassion were also rated highly (95%), along with confidentiality (90%). The chi-square test showed significant differences in the perception of professionalism (Chi2 = 140.80, P &lt; 0.001), and ANOVA demonstrated the impact of nurses' attitudes on trust (F = 116.93, P &lt; 0.001). Factor analysis indicated that professionalism and engagement were the primary components influencing trust perceptions, explaining 100% of variance. Conclusions. Professionalism, ethical conduct, and interpersonal skills are pivotal in establishing nursing as a public trust profession. These attributes are essential for patient trust and align with global standards in nursing practice. The study underscores the need to maintain high ethical and professional standards to sustain public trust in the profession.

The aim of the study was to investigate the effect of bee venom on the activity of two analgesics: ketoprofen (a non-steroidal anti-inflammatory drug) and tramadol (an opioid drug) in the acute thermal pain model (hot-plate test) in mice. Linear regression analysis was used to evaluate the dose-response relationship between logarithms of drug doses and their resultant maximum possible anti-nociceptive effects in the mouse hot-plate test. Doses that increased the anti-nociceptive effect by 20% (ED20 values) for bee venom, ketoprofen and tramadol, and their combination were calculated from linear equations. The interaction between bee venom and the selected anaglesics was evaluated using isobolographic analysis. The study showed that all compounds produced a definite anti-nociceptive effect, and the experimentally-derived ED20 values for bee venom, ketoprofen and tramadol, when applied indivisually, was 3.64mg/kg, 79.88mg/kg and 13.26mg/kg, respectively. Isobolographic analysis revealed that the combination of bee venom and ketoprofen at a fixed ratio of 1:1 was supra-additive (synergistic). The experimentally-derived ED20 mix was 26.33mg/kg, which significantly differed from the ED20 add of 41.76mg/kg (p < 0.5). The experimentally-derived ED20 mix of bee venom and tramadol was 2.90mg/kg, and differed significantly from the theoretically estimated ED20 add of 8.45mg/kg (p < 0.5), also indicating a synergistic interaction in the hot-plate test in mice. Moreover, none of the tested combinations indicated any adverse effects in the chimney test and the grip-strength test in mice. Overall, the obtained results demonstrated that bee venom significantly increased the anti-nociceptive activity of ketoprofen and tramadol in the hot-plate model of nociceptive pain in mice.

Background Age is a non-modifiable risk factor important in the etiology of many diseases. The ageing process of the body absolutely contributes to the degeneration of body tissues and the loss of function and the associated health-related quality of life (HR–QoL). Purpose Effect of age on HR–QoL among patients of 13 disease units. Matherial and methods The study was conducted among 7620 patients. The following age groups were included in the analysis: <30 years old, 30–39 years old, 40–49 years old, 50–59 years, 60–69 years, 70–79 years, and ≥ 80 years. The criterion for inclusion in the group was: age ≥ 18 years, written consent to participate in the study, treatment for chronic disease (at least 2 years), absence of other diseases and/or coexisting chronic symptoms. The SF-36 (Physical Component Summary (PCS); Mental Component Summary (MCS); Index of Life Quality (ILQ)) questionnaire was used to assess HR-QoL. Results The chance of having a better HR–QoL at 60–69 years of age decreases 3-fold (OR = 0.33) in MCS compared to the youngest group of patients. As far as PCS is concerned, there is a 5-fold lower chance of better HR–QoL (OR = 0.20). However, in the oldest group of patients, the chance of better HR–QoL in the MCS dimension is more than 12 times lower, and in PCS the chance of better HR–QoL is 33 times lower. A significant correlation between quality of life and age was confirmed. The level of PCS (R=-0.60), MCS (R=-0.50) and ILQ (R=-0.58) decreases with age. Cancer diseases (CD), regardless of the patient’s age, showed the strongest association with HRQoL among the 13 analyzed disease entities. The average level of HRQoL was the lowest. A decreased level of HRQoL was noted in patients with cardiovascular disease (CVD) aged 30–39 years. The highest HR–QoL was noted in the group of patients aged 40–49 years for both CD and CVD, in later years HR–QoL decreased in patients with CD and CVD. The chance of better HR–QoL decreases with age. After the age of 60, the highest decrease in HR–QoL is observed in both MCS and PCS. In all age groups, there is more often a chance of better HR–QoL in the MCS dimension than in PCS.

In this study, in order to determine the effect of matrices’ shape on the percolation threshold values, computer simulations were performed using the Monte Carlo method for a 200 × 200 square-shaped matrix and rectangular matrices containing the same number of nodes as the square matrix. Based on the simulations, the average values of the percolation thresholds and standard deviations for the current flow along and across the matrices were determined. It was determined that for a square-shaped matrix, the average values of the percolation thresholds in both directions of the current flow were the same. Extending the rectangular matrix while reducing its height causes the average value of the percolation threshold in the direction of the current flow along the matrix to increase from 0.592740 to 0.759847, while in the transverse direction, it decreases from 0.592664 to 0.403614. The values of the classical asymmetry coefficients of the probability distributions of the percolation thresholds for both directions of the current flow were determined. Histograms of the probability distributions of the percolation threshold values for a square-shaped matrix and rectangular matrices were made and compared with the normal distributions. It was found that the occurrence of two percolation thresholds in rectangular layers should be considered when analyzing the electrical conductivity measurements of nanocomposite thin films.
