Salivary apelin hormone response and dysfunctional attitudes in adolescents in Türkiye: a relational screening model.

BACKGROUND: Adolescence is the period in which physical and emotional changes occur through hormones, the individual acquires gender characteristics and prepares for the adult role psychologically and physically. Dysfunctional attitudes are beliefs and attitudes that can lead to depression by causing negative thoughts about oneself, others, and the future.Dysfunctional attitudes negatively affect children's mental health. Hormones have a significant impact on human behavior and cognitive functions. However, little is known about the role and influence of hormones on dysfunctional attitudes. Apelin is a hormone responsible for controlling emotions by regulating emotional behavior. The level of dysfunctional attitudes is one of the important issues in nursing practice in terms of protecting and improving children's mental health. However, little is known about the role and impact of hormones on dysfunctional attitudes.This study aimed to examine adolescents' dysfunctional attitudes and salivary apelin hormone levels in terms of sociodemographic variables. METHODS: The study was conducted in a relational screening model with 151 adolescents aged 9-14 years who were reported to be clinically healthy in Türkiye. Apelin hormone levels were analyzed by ELISA technique in the saliva samples of the participants. In the evaluation of dysfunctional attitudes, the relationship between the score obtained from the dysfunctional attitude scale and salivary hormone levels was evaluated. RESULTS: In the study, a negative, strong and statistically significant correlation was found between the average salivary apelin hormone level and dysfunctional attitudes of adolescents (p =.000). Mean salivary hormone levels of apelin in adolescent girls and boys were 0.696 (SD 0.052) ng/ml, respectively; while 0.671 (SD 0.047) ng/ml was determined (p =.002), dysfunctional attitudes scale scores were 52.95 (SD 14.43); it was determined as 59.04 (SD 14.22) (p =.006). On the other hand, the highest average salivary apelin hormone level (p =.038). and the lowest level of dysfunctional attitudes were determined in adolescent girls aged 13-14 years (p =.028). CONCLUSIONS: In our study, we found that while the salivary apelin hormone levels of adolescents decreased, their dysfunctional attitudes increased. We found that adolescents' dysfunctional attitudes decreased with age. In contrast, apelin hormone levels increased with age.

What do we know about beach soccer injuries? Systematic video analysis of four consecutive years with 580 match injuries.

The aim of the present study was to evaluate the characteristics of match injury in male beach soccer players. Video recordings of all official beach soccer tournaments in which the European national male beach soccer teams participated from 2018 to 2021 were analysed by two sports medicine specialists retrospectively. Regarding each injury, data including the mechanism, location of the injury, whether the injury led to time-loss, and the relationship of the injury to the bicycle kick (BK), etc. were documented. A total of 632 injuries were documented, corresponding to 234.9 injuries/1000 player hours. Video footage was available for 580 injuries. Whilst 79.8% of medical attention injuries occurred due to opponent contact, 19.5% of time-loss injuries occurred due to non-contact, and 12.2% of indirect opponent contact (p < 0.01). The most common location of the BK related injury was the head/neck (68.7%), whereas most common location of the BK unrelated injury was the lower extremity (54.1%) (p < 0.01). The findings demonstrated that beach soccer injury incidence was quite high; the most common injury location was head/neck and head/neck injuries were associated with BK. In light of these results, some rule regulations, particularly those associated with BK, and the use of protective equipment should be considered to prevent these injuries.

Diagnostic value of shear-wave elastography for patellar tendinopathy in female volleyball and basketball athletes: a cross sectional case control study.

OBJECTIVES: We aim to investigate the accuracy of shear-wave elastography (SWE) in diagnosing patellar tendinopathy in female volleyball and basketball players. In addition, we compared different parts of the patellar tendon and investigated the effects of different knee angles on elastography measurements. METHODS: This cross-sectional case-control study evaluated 63 female athletes from professional basketball and volleyball teams (NCT06199583). Patellar tendinopathy diagnoses were made using clinical and ultrasonographic criteria. SWE measurements were taken at 30-degree knee flexion and extension. Rectangular regions of interest boxes were placed in three different parts of the tendon (proximal, middle, distal). The global SWE value was calculated by taking the mean of measurements in the three parts. Receiver operating characteristic (ROC) curves were used to identify significant cutoff points for SWE, and 2 × 2 tables were generated to determine sensitivity and specificity. RESULTS: Thirteen (20.6%) of the 63 athletes were diagnosed with patellar tendinopathy. The ROC curves have identified different cutoff scores for SWE measurements. The SWE score of 130.75 from the proximal part showed the highest sensitivity of 89% and specificity of 80% (p < 0.001) with a 4.45 likelihood ratio at the 30-degree knee flexion. The likelihood ratio is 1.5 at a 30-degree angle and 1.65 at a 0-degree angle when measuring the entire tendon, whereas other portions indicate a ratio ranging from 1.12 to 1.73. CONCLUSIONS: Shear-wave elastography is a reliable evaluation method for diagnosing patellar tendinopathy. It has more accuracy when applied to the proximal part and at 30-degree knee flexion compared to measurements taken at knee extension and other parts of the tendon.

The team behind the team: prevalence and correlates of mental health problems among professional football team medical and allied staff?

This study aimed to evaluate depression, anxiety, and stress prevalence and correlates among professional football team medical and allied health staff (MAHS) in Turkey. An online survey was sent to all MAHS (n = 865) attending the professional development accreditation course organized at the end of the 2021-2022 football season in Turkey. Three standardized scales assessed depression, anxiety, and stress. A total of 573 staff participated (response rate = 66.2%). 36.7% of MAHS reported at least moderate severity depression, 25% anxiety, and 80.5% stress. Younger (26-33 years) and less experienced (6-10 years) MAHS reported higher stress scores than their older (50-57 years) and more experienced (>15 years) counterparts (p = 0.02 and p = 0.03, respectively). Masseurs (compared to team doctors) and staff without a second job (compared to those with a second job) reported higher depression and anxiety scores (p = 0.02, p = 0.03, p = 0.03, p = 0.02, respectively). Depression, anxiety, and stress scores of MAHS whose monthly income was less than $519 were higher than those whose income was more than $1036 (all p < 0.01). Findings demonstrated that professional football team MAHS suffer from symptoms of mental-ill-health at substantial rates. In light of these results, organizational policies should be implemented to proactively support the mental health of MAHS working in professional football.

Examining the mental health status of referees in the turkish professional football league.

OBJECTIVE: The purpose of the study was to evaluate the mental health (MH) status of referees who officiate in the Turkish professional football leagues. METHOD: An online survey was sent to all referees in the Turkish professional football leagues (n = 630) incorporating standardized scales assessing depression, anxiety, and stress. RESULTS: A total of 433 referees participated in the study, yielding a response rate of 68.7%. Younger referees (18-27 years) reported higher depression (p = 0.01), anxiety (p < 0.01), and stress (p < 0.01) scores than older (>38 years) refereees. Depression, anxiety, and stress scores of single referees were higher compared to married referees (all p < 0.01). Lower-level referees reported higher depression (p < 0.01), anxiety (p = 0.01), and stress (p < 0.01) scores than their higher-level counterparts. Higher depression, anxiety, and stress scores were also associated with less income, performance concerns, severe injury history, and inadequate social support. CONCLUSION: MH problems in referees were associated with a wide range of variables including younger age, being single, refereeing at lower-levels, performance concerns, and inadequate social support. In light of these results, MH assessments should be undertaken with referees to detect which officials are at greater risk of MH problems. Doing so will help to enable appropriate and timely MH interventions.

Which athletes are more vulnerable to mental health symptoms during the COVID-19 crisis? A cross-sectional study.

The present study evaluated the mental health (MH) of athletes according to a range of variables, including SARS-CoV-2 infection status and sport-specific factors. An online survey was sent to 1636 Turkish professional athletes incorporating standardized scales assessing athlete-specific stress, depression, and anxiety. A total of 579 professional athletes (29% SARS-CoV-2 positive) participated in the study. While female athletes reported higher anxiety scores than males (p < 0.01), the depression scores of the athletes who had been infected with SARS-CoV-2 were significantly higher than athletes who were not infected (p = 0.03). Higher athlete-specific stress, depression, and anxiety scores were associated with participating in an individual sport, experiencing chronic pain, severe sports injury history, and performance concerns (all p < 0.01). MH symptoms in athletes were associated with being infected with SARS-CoV-2, female gender, participating in an individual sport, and performance concerns. MH assessments should be undertaken with athletes to detect vulnerabilities and enable appropriate and timely MH interventions.

Mental health problems and risk assessment in football players infected with SARS-CoV-2: a cross-sectional study.

BACKGROUND: Although the negative psychological impact of the pandemic on athletes is well known, there is currently insufficient evidence regarding mental health (MH) problems among athletes infected with SARS-CoV-2. The aim of the present study was to evaluate the association between MH problems, demographics, and SARS-CoV-2 related variables in football players infected with SARS-CoV-2. METHODS: An online survey included demographic questions, SARS-CoV-2 related questions, the Athlete Psychological Strain Questionnaire, and the Depression Anxiety Stress Scales-21 was distributed to male and female professional football players aged between 18-38 and infected with SARS-CoV-2. RESULTS: A total of 261 football players participated in the study. The odds of athlete-specific distress in lower-level football players were up to 5.9 times more than those competing at the highest level (OR=3.06-5.93, 95% CI: 1.27-14.43, P<0.01). The odds of depression and stress in lower-level football players were up to 6.7 times more than those competing at the highest level (both OR=3.70-6.77, 95% CI: 1.18-19.20, P<0.01). In players who reported sleep problems, there was increased risk of athlete-specific distress (OR=2.43, 95% CI: 1.31-4.52, P<0.01), depression (OR=3.71, 95% CI: 1.98-6.95, P<0.01), anxiety (OR=2.93, 95% CI: 1.62-5.28, P<0.01), and stress (OR=7.08 95% CI: 3.52-14.02, P<0.01). There was increased risk of depression and stress in female players (OR=5.78, 95% CI: 2.03-16.4, P<0.01; OR=4.91, 95% CI: 1.57-15.4, P<0.01; respectively). The odds of anxiety in players who reported severe SARS-C0V-2 symptoms were up to 2.2 times more than asymptomatic players (OR=2.28, 95% CI: 1.08-4.82, P=0.03). CONCLUSIONS: MH problems in football players infected with SARS-CoV-2 were associated with female gender, participation in football in the lower-level, performance concerns, and sleep problems. MH assessment is indicated in athletes infected with SARS-CoV-2 to support detection, and appropriate and timely intervention.

Injuries in elite level male beach soccer players: a prospective three year study.

OBJECTIVES: The aim of this study was to investigate the incidence and characteristics of match and training injuries in elite-level national male beach soccer players. METHOD: The incidence, mechanism, location, type, severity, and burden of injuries of the Turkish national beach soccer team were recorded between 2017 and 2019. RESULTS: A total of 136 injuries occurred during the study period. Total injury incidence was 238.9 injuries/1,000 match hours (MHs) and 37.7 injuries/1,000 training hours (THs) (p < 0.001). Twenty-seven injuries led to time-loss, and the incidences for match and training injuries were 36.7 and 7.9 per 1,000 hours, respectively. Of medical attention injuries (MAI) caused by trauma, 54.6% (n = 53) were due to another player and, 60.9% (n = 14) of time-loss injuries (TLI) caused by trauma were due to non-contact trauma (p < 0.001). While 82% (n = 91) of training injuries occurred in lower extremities, 29% (n = 9) of match injuries occurred in the head/neck region (p < 0.001). Head injury incidence was 45.9 per 1,000 match hours. Of MAI, 50% (n = 57) were contusion, and 32.1% (n = 9) of TLI were strain (p < 0.001). Also, the most common injury subtype was foot/toe contusion during match and training (19.4%; n = 6, 27.9%; n = 31, respectively). The majority of injuries 91.9% (n = 125) had slight severity. CONCLUSION: Head trauma, tendon injury, and foot/toe contusion are important for clinical practice in beach soccer. Protective measures (rule regulation, use of protective equipment, etc.) should be considered to prevent these injuries.

Comparison of the functional and cardiovascular effects of home-based versus supervised hospital circuit training exercises in male wheelchair users with chronic paraplegia.

OBJECTIVES: The aim of this study was to compare the efficacy of home-based upper extremity circuit training exercises (CTEs) with supervised hospital program in male patients with traumatic complete paraplegia. PATIENTS AND METHODS: Twenty men with paraplegia (mean age: 38±10.1 years; range, 30 to 43 years) between January 2007 and November 2007 were randomized into two groups. The first group had supervised hospital CTE program, whereas the second group had home-based CTE. The effects of the upper extremity CTE by using elastic bands 60 min per day, five days a week, for a total of eight weeks (70% maximal oxygen consumption [VO2max]) were examined. The Cybex was used for the isokinetic testing of the upper extremities. The VO2max and maximum heart rate (HR) were assessed using an arm ergometer. The Craig Handicap Report Technique Short Form (CHART-SF) was used for the evaluation of functional independence and mobility. Serum lipid profiles were measured. RESULTS: The mean injury duration was 7.9±2 years. The peak torque values of the upper extremities, VO2max, maximum HR, CHART-SF physical independence and mobility scores, and serum lipid profile were all improved in both groups (p<0.05). There were no significant differences in terms of the increase in the muscle strength and serum lipid levels between the groups (p>0.05). The improvement in the VO2max, physical independence, and mobility scores were greater in the supervised exercise group. CONCLUSION: Upper extremity strength, cardiovascular endurance, and lipid profile were improved after supervised and home-based CTE in the men with paraplegia. Home-based exercise programs may be good alternatives to the hospital rehabilitation for this patient population.

Adipokine, gut and thyroid hormone responses to probiotic application in chukar partridges (Alectoris chukar) exposed to heat stress.

The aim of this study was to investigate the effect of Lactobacillus reuteri E81 (LRE) probiotic supplementation on heat stress responses in chukar partridges (Alectoris chukar). The birds were divided into two groups, one of which was exposed to heat stress (HS). Within each group, four subgroups, each including 64 birds, were created for the three treatment doses (200, 400 or 600 mg/kg) of LRE and the control. The experiment was started with day-old birds, kept at a temperature of 25 °C or 37 °C. After a 7-day adjustment period, the LRE supplementation lasted for 35 days. The levels of different adipokines, including visfatin (VF), adiponectin (ADP), chemerin (CHEM), as well as the concentration of plasma citrulline (CIT) and the levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH) in the blood were measured at 21 and 42 days of age. A significant correlation (P < 0.01) was found between LRE supplementation and the decrease in serum VF, ADP, CIT, T3 and T4 levels in partridges exposed to HS. On the other hand, no significant relationship was found between LRE supplementation and the serum CHEM and TSH levels (P > 0.05). We concluded that the addition of 600 mg/kg LRE is beneficial in preventing intestinal damage and inflammation provoked by HS.

Prevalence of femoroacetabular impingement and effect of training frequency on aetiology in paediatric football players.

PURPOSE:: The aim of this study was to determine the prevalence of asymptomatic radiographic findings of femoroacetabular impingement (FAI) in paediatric football players in different age groups and to investigate aetiological factors. METHODS:: Paediatric male athletes between 10 and 17 years of age from 8 soccer teams were recruited. In addition to an annual control check-up, anteroposterior pelvis and frog-leg radiographs as well as the curriculum vitae of the athletes, their injuries, and real-time complaints were recorded. The alpha angle, lateral centre-edge angle, Tönnis angle, and collodiaphyseal angle were measured and morphological abnormalities were noted. RESULTS:: There were 214 male football players with a mean age of 13.4 ± 3.2 years included in the study. In the morphological analysis of hips, there was FAI in 30% of the athletes. In the analysis of FAI prevalence in 3 subgroups based on age (Group 1: 10-12 years [ n = 25], Group 2: 13-15 years [ n = 104], Group 3: 16-17 years [ n = 85]), there was 0% FAI in Group 1, 19.1% in Group 2 and 60% in Group 3. In the analysis of aetiological factors, there was no significant difference between the right and left hips of players regarding alpha angles and FAI prevalence. However, the prevalence of FAI was higher in players who had been playing football for 3 years or more and who had been training for 12.5 hours/week or more. CONCLUSION:: Training for 12.5 hours or more per week in paediatric football players doubled the risk development of FAI morphology.

Effects of special exercise programs on functional movement screen scores and injury prevention in preprofessional young football players.

To increase movement capacity and to reduce injury risk in young soccer players by implementing a special functional exercise program based on functional movement screen (FMS) and correctives. 67 young male athletes 14-19 years of age from a Super League Football Club Academy participated in the study. Functional movement patterns were evaluated with FMS assessment protocol. Deep squat, hurdle step, inline lunge, shoulder mobility, active straight leg raise, trunk stability push-up, and rotatory stability were examined in FMS. Considering the FMS scores the number of intervention and control groups were defined as 24 and 43, respectively. Intervention program was composed of 1 hr twice a week sessions in total of 12 weeks with 4 weeks of mobility, 4 weeks of stability, and 4 weeks of integration exercises. At the end of 12-week intervention and control groups were re-evaluated with FMS protocol. Contact and noncontact sports injuries recorded during one season. In intervention group there was statistically significant difference in increase in total FMS scores (P<0.01), deep squat (P≤0.001), hurdle step (P<0.05), inline lunge (P<0.01), and trunk stability push-up (P<0.01). In control group total FMS, deep squat, and trunk stability push-up scores increased with a statistical difference (P<0.01, P<0.05, P≤0.01, respectively). The incidence of noncontact injury in control group was higher than intervention group (P<0.05). Periodic movement screening and proper corrections with functional training is valuable in order to create better movement capacity to build better physical performance and more effective injury prevention.

The effects of compression garments and electrostimulation on athletes' muscle soreness and recovery.

In this study, we explained the effects of compression garment and electrostimulation on athletes' recovery period by evaluating blood lactate and isokinetic peak torque parameters. Twenty volunteers (15.55± 0.51 yr) were included to study. At recovery period, blood samples was taken for lactate values at 0th, 3rd, 5th, 15th, 30th min. The isokinetic strength test was performed on right ankle at 15th min and on the left ankle at 30th min. The same protocol was performed for compression garment on 2 weeks and for electrostimulation on third weeks and results were compared. There wasn't any significant difference on blood lactate levels within groups. At women; there was not any significant difference on isokinetic peak torques within two groups. but at electro-stimulation usage we found significant increases on right plantar flexion (P<0.1), right dorsal flexion (RDF) (P<0.1) and left plantar flexion (LPF) (P<0.1) values compared to control measurements. At men; with compression garment usage, there was significant increase on LPF values compared to control measurements. At electrostimulation usage, we found significant increases on RDF (P<0.1) and left dorsal flexion (P<0.1) values compared to control measurements. During recovery, there is not any beneficial effect seen on blood lactate level within two groups. When compared to passive rest, compression garments and electrostimulation interventions effects on force generation capacity at recovery are statically significant. Also in terms of force generation capacity; usage of electrostimulation during 15 min and compression garments during 30 min were statically more significant.

Assessment of P wave duration and P wave dispersion in high level football referees.

BACKGROUND: P wave dispersion and P wave maximal duration reflect the activation of atrial muscle and is influenced by the mass of the excited tissue. It may reflect atrial remodelling, most likely atrial fibrosis. The purpose of this study was to measure P wave duration and P wave dispersion in the high level football referees. METHODS: We recruited 104 elite and national referees with a training history of many years. The control group was made of 32 healthy sedentary subjects. The difference between P maximum and P minimum durations was defined as P wave dispersion. Echocardiographic parameters such as left atrial diameter were assessed with a Vivid 3 cardiovascular ultrasound system [3S sector probe (1.5-3.6 MHz), GE]. RESULTS: P wave maximum duration, P wave dispersion, left ventricle posterior wall thickness, inter-ventricular septum thickness and left atrial diameter were increased in the football referees as compared with healthy sedentary subjects. There were significant correlations of P wave dispersion with left atrial diameter and left ventricle posterior wall thickness CONCLUSIONS: P wave maximum duration, P wave dispersion and left atrial diameter were increased in the football referees. Also, there was a significant correlation between P wave dispersion and left atrial diameter.

Injury evaluation of the Turkish national football team over six consecutive seasons.

BACKGROUND: The aim of our study was to evaluate the incidence, mechanisms and anatomic sites of injuries of the Turkish National Men's Football Team over six years. METHODS: The affected anatomic site, incidence rate, type of injury, and applied treatment procedures were recorded by the medical staff. Official and friendly games and training sessions over the period January 2000 - December 2005 were documented daily. Cross- tabulation, frequency analysis, descriptive statistics, and chi-square test methods were used in statistical evaluations. RESULTS: In total, 52 official and friendly games were played and 208 training sessions were conducted. The total number of injuries recorded in this period was 108, and the averages per match and training were 1.0 and 0.27, respectively. The most commonly affected anatomic site was the thigh (25%), the most common injury type was contusion (32%) and the most common applied treatment procedure was physical therapy and rehabilitation (89.8%). CONCLUSION: Our results provide valuable information about the incidence, affected anatomical site, and type and severity of injuries in football. This study can serve as reference data for future scientific studies in the field, and also provides information regarding the prevention of injuries.

The mendosal suture.

PURPOSE: The knowledge regarding the mendosal suture is still on debate in the literature. Though reports of the closure of this childhood suture are variable, a few reports show the presence of the suture in the adults. This study was conducted to determine the occurrence and a better topographic location of the mendosal suture. METHODS: We used 129 dry skulls for this study. In the specimens, which were determined to have a mendosal suture, the morphometric traits of the mendosal suture and the angle between the mendosal suture line and lambdoidal suture line (α angle) were measured. RESULTS: We found mendosal suture on 18 specimens, 11 of them were bilateral and 7 were unilateral. The length of these sutures ranged from 10.4 to 23.8 mm on the right side and 10.8 to 31.6 mm on the left side, respectively. The angle between two suture lines ranged from 36 to 68° on the right side and 32 to 75° on the left side. CONCLUSIONS: We believe that, these data will be of use to clinicians in order to avoid any misinterpretation of the mendosal suture with cranial fractures.

Assessment of the p wave dispersion and duration in elite women basketball players.

BACKGROUND: P wave dispersion is an independent predictor of atrial fibrillation. P wave dispersion is associated with inhomogeneous and discontinuous propagation of sinus impulses. The purpose of this study was to investigate P wave dispersion and transthoracic echocardiographic findings in elite women basketball players. METHODS: We recruited 27 well-trained woman athletes with a training history of many years (11.9 +/- 3.6 years). All of the athletes were elite women basketball players and they were regularly maintaining sportive activities and training programs. Twenty-six age and sex matched healthy sedentary subjects consisted of control group. The difference between P maximum and P minimum durations was defined as P wave dispersion. The echocardiographic parameters were assessed in detail in the standard left lateral decubitus position. RESULTS: The body height, body weight, body surface area, metabolic equivalent, maximum P wave duration and P wave dispersion were increased in the elite basketball athletes as compared with healthy sedentary subjects. On the contrary; the heart rate, ejection fraction and interventricular septum thickness in diastole were decreased in athletes. The body height (p=0.006, r=0.37), body weight (p=0.04, r=0.28), body surface area (p=0.01, r=0.33) and heart rate (p=0.01, r=-0.32) were correlated with P wave dispersion. CONCLUSIONS: P wave dispersion was increased in elite woman basketball players as compared with healthy sedentary subjects. P wave dispersion was correlated with heart rate, body height, body weight and body surface area.

Foramen of vesalius.

OBJECTIVE: To investigate the frequency of unilateral or bilateral foramen of Vesalius (FV), number of FV present on one side, and presence of a septum on FV. METHODS: We bilaterally examined, 347 sphenoid bones of collections of the Department of Anatomy, Istanbul Faculty of Medicine, Istanbul University, Istanbul and Dokuz Eylul Faculty of Medicine, Izmir, Turkey in 2007. RESULTS: Of the 347 bilaterally examined skulls, 87 (25.1%) had bilateral FV, 191 (55%) specimens did not have any FV on both sides, and 69 specimens (19.9%) had unilateral FV (33 skulls had FV on the right side, and the remaining 36 skulls had FV on the left. Of the 156 skulls which had FV, only 4 skulls 3 on the right, one on the left) had double FV on the same side. We have not observed any specimens which had 3 or more FV on the same side. Of the 156 skulls which had FV, 11 skulls had a septum on FV, 3 skulls had a septum on FV on the right side, and 6 skulls had a septum on FV on the left side. Two skulls bilaterally had a septum on both sides. CONCLUSION: We believe that our data about FV will be enlightening not only for anatomists, but also for clinicians.
