Tourniquet Effect on Patients Undergoing Total Knee Arthroplasty: A Single-Blind, Randomized Controlled Trial.

Tourniquet is applied in Total Knee Arthroplasty (TKA) to reduce intraoperative blood loss and improve view of surgical field. However, tourniquet use in TKA is still in dispute. Some researchers find that tourniquet may lead to extra side effects such as aggravated pain and limb swelling, while others consider that tourniquet has no significant adverse impact on clinical outcomes of TKA patients. This trial is conducted to evaluate tourniquet effect on TKA patients. A prospective, single-blind, randomized controlled trail is adopted with a sample size of 130 knees from August 2020 to February 2023. Patients undergoing TKA are randomly allocated to tourniquet group and non-tourniquet group. Outcomes including quadriceps thickness and stiffness, operation time, total blood loss, intraoperative blood loss, postoperative blood loss, transfusion rate, thigh circumference, knee and thigh VAS, D-Dimer and CRP level, knee function score, patient satisfaction, and complications are evaluated in this trial. Student's t-test, Mann-Whitney U test, Pearson's chi-square test, and Fisher's exact test are used in this study. No significant difference in demographic information and baseline outcomes were found (p > 0.05). Participants in the tourniquet group had significantly less total blood loss and intraoperative blood loss, more postoperative blood loss, and higher D-Dimer level on postoperative day 3 when compared with non-tourniquet group (p < 0.05). Other outcomes including quadriceps thickness and stiffness, operation time, postoperative blood loss, transfusion rate, thigh circumference, knee and thigh VAS, D-Dimer level on postoperative day 1, CRP level, knee function score, patient satisfaction, and complications showed no significant difference (p > 0.05). Tourniquet application can effectively reduce intraoperative blood loss and total blood loss, without significant side effects. Hence, we advocate the regular use of tourniquet in primary TKA.

Association between muscle-localized bioelectrical impedance analysis parameters and performance in a multi-set exercise on the isokinetic dynamometer in young women.

This study aimed to verify the relationship between changes in thigh muscle-localized bioelectrical impedance analysis (ML-BIA) parameters and performance in a multiple-set exercise. The sample consisted of 30 female university students (22.1±3.2years). The ML-BIA parameters, including localized muscle resistance (ML-R), reactance (ML-Xc), and phase angle (ML-AngF), were evaluated using a tetrapolar bioelectric impedance device operating at a frequency of 50KHz. The multiple sets protocol was performed with an isokinetic dynamometer. For body composition, total and leg lean soft tissue (LST) were evaluated using dual X-ray absortiometry. Student's t-test for paired samples was used to compare the ML-BIA parameters and thigh circumference pre and postexercise. Linear regression analysis was performed to verify the ∆ML-PhA as a predictor of peak torque for the three sets alone while controlling for total and leg LST. There were differences in the ML-R (∆=0.02±1.45Ω; p=0.001; and E.S=0.19), ML-Xc (∆=2.90±4.12Ω; p=0.043; and E.S=0.36), and thigh circumference (∆=0.82±0.60cm; p<0.001; and E.S=0.16) pre- and post-multiple sets. ΔML-PhA was a predictor of performance in the first set (p=0.002), regardless of total and leg LST. However, the ΔML-PhA lost its explanatory power in the other sets (second and third), and the variables that best explained performance were total and leg LST. The ML-BIA (ML-R and ML-Xc) parameters were sensitive and changed after the multiple sets protocol, and the ΔML-PhA was a predictor of performance in the first set regardless of the total and leg LST.

Effects of combining rehabilitation training on the recovery of athletic ability after reconstruction of injured ligament

This paper aims to investigate the impact of conventional rehabilitation training and neuromuscular electrical stimulation (NMES) on the recovery of motor abilities in patients following ligament injury reconstruction. Forty postoperative patients who underwent surgery for anterior cruciate ligament reconstruction (ACLR) were randomly allocated to either the conventional rehabilitation group or the NMES group. The NMES group received NMES treatment in addition to the conventional rehabilitation program starting from eight weeks postoperatively. Various parameters, including knee joint function, stability, and balance, were compared between the two groups at eight weeks and 12 weeks postoperatively. Compared to the data at eight weeks postoperatively, both groups exhibited significant improvements in all measured indicators at 12 weeks postoperatively (p < 0.05). In the 12th week after the surgery, the NMES group demonstrated a Lysholm score of 93.18 ± 3.67 points, an IKDC score of 84.65 ± 2.33 points, a KT-2000 measurement of 0.88 ± 0.45 mm, a thigh circumference difference of −1.33 ± 0.55 cm, a knee flexion angle of 130.12 ± 4.21°, a single-leg standing time of 60.12 ± 9.33 s, a YBT score of 70.26 ± 2.68 points, and a Bulgarian split squat 1RM size of 58.07 ± 6.85 kg; all of these results were significantly superior to those observed in the conventional group (p < 0.05). NMES significantly enhances the recovery of athletic ability in patients following postoperative ACLR and can be effectively applied in clinical practice.

Enhancing lower limb and core muscle activation with blood flow restriction training: a randomized crossover study on high-intensity squat exercises.

The primary objective of this study was to assess the impact of high-intensity deep squat training integrated with various blood flow restriction (BFR) modalities on the activation of lower limb and core muscles. A randomized, self-controlled crossover experimental design was employed with 12 participants. The exercise protocol consisted of squat training at 75% of one-repetition maximum (1RM), performed in 3 sets of 8 repetitions with a 2-min inter-set rest period. This was conducted under four distinct BFR conditions: continuous low BFR (T1), intermittent medium BFR (T2), intermittent high BFR (T3), and a non-restricted control (C). Surface electromyography (EMG) was utilized to collect EMG signals from the target muscles during the BFR and squat training sessions. The root mean square (RMS) amplitude standard values were calculated for each squat set to quantify muscle activation levels, with these values expressed as a percentage of the maximum voluntary contraction (%MVC). Rating of Perceived Exertion was evaluated after each squat set, and leg circumference measurements were taken. 1) During the first two sets of deep squats, the %MVC of the vastus lateralis and vastus medialis in all compression groups was significantly higher than that in the control group (p < 0.05). Furthermore, in the first set, the %MVC of the vastus lateralis in Group T3 was significantly higher than in Group T2 (p < 0.05). In the third set, the %MVC of the vastus medialis in Groups T1 and T3 was significantly lower than in the first two sets (p < 0.05). 2) Group T1 showed an increased activation of the biceps femoris and semitendinosus muscles in the second and third sets, with %MVC values significantly greater than in the first set (p < 0.05). Group T2 only showed an increase in biceps femoris activation in the third set (p < 0.05). Group T3 significantly increased the activation of the biceps femoris and semitendinosus muscles only in the first set (p < 0.05). 3) No significant differences were observed in the changes of rectus abdominis %MVC among the groups (p > 0.05). In the first set, Group T3's erector spinae %MVC was significantly higher than the control group's; in the second set, it was significantly higher than both Group T2 and the control group's (p < 0.05). 4) After training, a significant increase in thigh circumference was observed in all groups compared to before training (p < 0.05). 5) For RPE values, Group T2's post-squat values were significantly higher than the control group's after all three sets (p < 0.05). Group T1's RPE values were also significantly higher than the control group's after the third set (p < 0.05). Groups T1, T2, and C all had significantly higher RPE values in the second and third sets compared to the first set (p < 0.05). All BFR modalities significantly enhanced the activation level of the anterior thigh muscles, with the continuous low BFR mode demonstrating a more stable effect. No significant differences were found in the activation level of the rectus abdominis among the groups. However, the intermittent high BFR mode was the most effective in increasing the activation level of the erector spinae muscles. While BFR did not further augment leg circumference changes, it did elevate subjective fatigue levels. The RPE was lowest during squatting under the intermittent high BFR condition.

A Comparative Study of Body Composition and Aerobic Capacity between Water and Land Exercise Walking in Male College Students with Mild Obesity

This study explores the impact of water and land fitness walking on the body composition and aerobic capacity of mildly obese male college students. Employing a randomized controlled trial, 36 mildly obese male college students were divided into a water group, a land group, and a non-intervention control group. Following a 4-week exercise intervention, dual-energy X-ray absorptiometry and power bicycle tests assessed body composition and aerobic capacity. The results revealed that both the water and land groups significantly enhanced relative maximum oxygen uptake and lactate threshold, with the water group showing greater improvement. Additionally, water fitness walking significantly reduced body composition indicators including body weight, BMI, waist circumference, waist-to-hip ratio, and thigh circumference. However, there were no significant changes in height, chest circumference, muscle mass, and bone density. The research indicates that water fitness walking uniquely enhances aerobic exercise capacity and body composition, offering a scientific foundation for college students to select effective weight loss exercise methods.

Examining the Relationship between Foot Medial Arch Height and Short and Medium Distance Running Performances and Some Variables in Athletes

In this study, the relationship between foot medial arch height, age, height, body weight, body mass index (BMI), calf and thigh thickness and 100-meter and 3000-meter running performances in athletes was investigated. 28 athletes competing in national competitions, with an average age of 18.29±5.68 years, were included in the study on a voluntary basis. The right foot medial arch heights, heights, body weights, calf and thigh thicknesses of the participants were determined. BMI's were calculated. Also, 100 m and 3000 m. running times were determined. Data analyzes were performed using descriptive statistics and correlation tests. As a result of the analysis, 100 m running performance had a negative relationship with the values of height (r= -.377), body weight (r= -.466), BMI (r= -.428) and thigh circumference (r= -.433). It was observed that there was a relationship with the calf circumference measurement value (-.496) at the p&amp;lt;0.01 level. On the other hand, it was determined that the relationship between foot medial arch height (r= -.178) was not significant (p&amp;gt;0.05). On the other hand, 3000 m running performance was negatively affected by height (r= -.493), body weight (r= -.641), BMI (r= -.625) and calf girth thickness (r= -.623). It was determined that it showed significance at the p&amp;lt;0.01 level. It was also determined that there was a significant relationship with medial arch height in a negative direction (r = -.404) and at p &amp;lt; 0.05. As a result, it can be said that foot medial arch height, height, body weight, BMI, thigh and calf circumference thickness values are effective on short and medium distance running performances.

The Relationship Between Some Anthropometric Measurements and Pulmonary Volumes to the Numerical Achievement of 800-Meter Event Runners in Palestine

The study aimed to identify the contribution of some anthropometric measurements and pulmonary volumes to the Numerical Achievement of runners in the 800-meter running event at Palestine. The study was conducted on a purposely-designed sample of (17) runners in Palestine, aged between (18-22) years. The researchers used the descriptive analytical approach because it suits the nature of the study. Anthropometric measurements were performed related to (age, body mass, height, arm length, leg length, thigh length, lower leg length, instep length, chest circumference, chest circumference with inspiration, abdominal circumference, thigh circumference, and Leg calf, upper arm circumference, and related Pulmonary volume measurements. Related Pulmonary volume measurements were performed (VC, FVC, FEV1, FWV1/FVC%, MVV, TV, RV), and after the data was collected, it was processed statistically using SPSS. The results of the study showed that the anthropometric measurement that have the most contribution In the Numerical Achievement of 800 meters running event runners in Palestine was Height, which contributed to explaining (43.1 %) of the finishing time. The study also found that Pulmonary volume measurements contributed most to the Numerical Achievement For runners of the 800- meter running event in Palestine, was Vital Capacity (VC)which explained (39.1%) of the time Achievement. Researchers recommend that the predictive equations that have been developed should be used as predictors for the numerical achievement of the 800-meter running event.

A randomized, double-blinded, placebo-controlled, single-center, comparative study evaluating Phaseolean® safety and efficacy in overweight/obese participants

ScopePhaseolean®, a standardized water extract of Phaseolus vulgaris or white kidney bean, exhibits α-amylase inhibitory property, which decreases calorie absorption by preventing or delaying carbohydrate digestion, thus supporting weight management. This randomized, double-blind, placebo-controlled, single-center comparative study (Clinical trial registration number: CTRI/2023/02/049440, Registered on: February 03, 2023) evaluated the safety and efficacy of Phaseolean® in weight management in overweight or obese participants upon regular intake at two different doses compared with placebo. MethodSixty-six participants were enrolled and randomly divided into three groups, considering the inclusion & exclusion criteria. Each group was assigned a specific daily dosage for three meals: Phaseolean® 1500 mg/day (500 mg per meal), Phaseolean® 3000 mg/day (1000 mg per meal), or placebo 1500 mg/day (500 mg per meal), administered thrice a day before meals for 45 consecutive days. Body weight; body mass index (BMI); skinfold fat thickness; waist, hip, and thigh circumferences; and blood biochemical parameters were monitored and analyzed to evaluate the effects of these interventions. Results and conclusionsOf the 66 enrolled participants, 62 completed the study. Treatment with Phaseolean® 1500 mg/day reduced the weight by an average of 2.10 kg (0.33 kg/week), while that with 3000 mg/day was 1.94 kg (0.30 kg/week); 0.13 kg weight loss (0.02 kg/week) was observed in the placebo group after 45 days, showing significant differences between the Phaseolean® and placebo groups (p < 0.01). BMI, body fat, skinfold fat thickness, and the waist, hip, and thigh circumference were significantly reduced (p < 0.01) in both Phaseolean® groups compared with those in the placebo group, which showed no significant changes.No adverse effects were observed during the clinical trial period. Phaseolean® 1500 mg/day dose was more effective in weight reduction than the 3000 mg/day higher dose. Therefore, Phaseolean® can be used to support healthy weight management.

Effects of a physical exercise programme on bodyweight, body condition score and chest, abdominal and thigh circumferences in dogs

BackgroundResearch on the effects of physical exercise on canine body composition is limited. The aim of this study was to investigate the effects of a physical exercise programme on bodyweight, body condition score (BCS) and chest, abdominal and thigh circumferences in dogs. Twenty-one healthy dogs of different breeds exercised together with their owners during an eight-week programme consisting of jogging and strength exercises. Standardised measurements were performed in triplicates with a measuring tape on standing dogs. Chest circumference was measured at three anatomical locations, abdomen at two and thigh at one. Data on bodyweight, BCS (9-point scale) and circumferences were analysed with mixed model repeated measures analyses to evaluate changes after the programme and effects of target distance.ResultsSeven dog owners choose a target distance of 2 km and 14 owners choose 5–10 km. Mean BCS decreased (P = 0.007) after the programme (5.1 ± 0.9 vs. 4.7 ± 0.6) but there was no effect of target distance. Almost all chest and abdominal circumference measurements decreased (P ≤ 0.007) with the 2 km group driving the reduction in chest circumference and the 5–10 km group driving the reduction in abdominal circumference. In contrast, thigh circumference (28.8 ± 0.4 vs. 30.2 ± 0.4) increased (P = 0.007) while bodyweight was maintained. There were positive correlations between BCS and abdominal/chest ratios before and after the programme (Pearson correlation; R square ≤ 0.43, P ≤ 0.0012) but the mean ratio remained constant.ConclusionsResults indicated a redistribution between total body fat and muscle mass in body composition of normal weight to slightly overweight dogs after the physical exercise programme. The use of bodyweight alone was not a reliable evaluation method to complement the BCS assessment. However, repeated measurements of chest, abdominal and thigh circumference might aid in the assessment of body composition in dogs performing physical exercise. Further research should include a control group and objective evaluations of total body fat and lean mass, in order to investigate the effectiveness of physical exercise as a freestanding method for decreasing BCS and increasing muscle mass in overweight dogs.

Comparative Study of Two Different Access Points, One Tibial Vein and the Popliteal Vein, for Catheter-Directed Thrombolysis in the Treatment of Acute Mixed Lower Extremity Deep Vein Thrombosis

Although the popliteal vein approach is commonly used for catheter-directed thrombolysis (CDT) treatment in patients with acute lower extremity deep vein thrombosis (DVT), CDT via a new access route, the posterior tibial vein, is also used and has demonstrated good results. However, this tibial approach has not been tested in large samples. In this article, we compare the early efficacy of CDT using the tibial and popliteal vein approaches for the treatment of acute mixed lower extremity DVT. In this retrospective cohort study, 87 patients with acute mixed lower extremity DVT treated at the Department of Interventional Medicine of Zhuhai People's Hospital were enrolled; those with tibial vein access and popliteal vein access were included in the observation (n=55) and control (n=32) groups, respectively. The safety and efficacy of CDT via tibial vein access were investigated by collecting and comparing indicators such as venous patency, thrombus removal effect, thigh and calf circumference difference, swelling reduction rate of the affected limb, surgical complications, and postdischarge complication rate of the patients in the 2 groups. The postoperative thrombus clearance effect of the observation group was significantly better than that of the control group (P<0.05), and the postoperative venous patency rate of the observation group was 83.2±15.7%, which was higher than that of the control group (62.2±38.2%) (P=0.005). The swelling reduction rate of the lower extremity was 74.0±33.8% in the observation group and 51.4±30.0% in the control group, with a statistically significant difference (P=0.002). However, there was no statistically significant difference (P>0.05) in the rates of thigh swelling reduction, bleeding-related complications, or postoperative complications between the 2 groups of patients. CDT via the tibial vein approach is safe, effective, and may be a better approach for CDT access, offering superior thrombus clearance, venous patency, and lower extremity swelling reduction postoperatively.

Early Postoperative Rapid Rehabilitation Yields More Favorable Short-term Outcomes in Patients Undergoing Patellar Realignment Surgery for Recurrent Patellar Dislocation: A Prospective Randomized Controlled Study.

Use of a rapid rehabilitation protocol for postoperative recovery after recurrent patellar dislocation (RPD) has gradually gained attention; nonetheless, evidence of its safety and effectiveness is lacking. To compare the short-term postoperative outcomes of early rapid rehabilitation with those of conservative rehabilitation in patients with RPD. Randomized controlled trial; Level of evidence, 2. A total of 50 patients with RPD who underwent tibial tubercle osteotomy combined with medial patellofemoral ligament reconstruction were enrolled between January 2018 and February 2019. Postoperatively, the patients were randomly assigned to either the early rapid group (rapid group; n = 25 patients) or the conservative group (control group; n = 25 patients) for rehabilitation training. The rapid group underwent faster progression in weightbearing and range of motion (ROM) training. Knee joint functional scores, ROM, bilateral thigh circumference differences, and imaging data were recorded preoperatively and at 6 weeks and 3, 6, 12, and 24 months postoperatively for comparison. Postoperative complications were recorded over the 24-month follow-up period. The baseline data did not significantly differ between the 2 groups. Postoperatively, compared with the control group, the rapid group had higher Tegner scores at 6 weeks and 3 months; higher Lysholm scores at 3 and 6 months; higher International Knee Documentation Committee scores at 6 weeks, 3 months, and 12 months; better ROM; and smaller bilateral thigh circumference differences at 24 months (P < .05 for all). However, no differences were observed in the Tegner, Lysholm, and International Knee Documentation Committee scores at 24 months postoperatively. At the 6-week and subsequent follow-up visits, the Caton and Insall indices were lower in the control group than in the rapid group (P < .01 for all). Moreover, compared with the control group, the rapid group had a lower incidence of patella baja at 24 months (0% vs 17%) and fewer complications during the whole follow-up period (P < .01). Early rapid postoperative rehabilitation appears to be safe and effective for patients who undergo tibial tubercle osteotomy combined with medial patellofemoral ligament reconstruction to treat RPD. In the short term, this approach was shown to be more advantageous than conservative rehabilitation in improving functional scores, allowing an earlier return to daily activities, although the lack of difference at 24 months implies no long-term benefits. In addition, it potentially helped to prevent the occurrence of complications, including patella baja. ChiCTR1800014648 (ClinicalTrials.gov identifier).

Differences in Type 2 Fiber Composition in the Vastus Lateralis and Gluteus Maximus of Patients with Hip Fractures.

Aging leads to sarcopenia, which is characterized by reduced muscle mass and strength. Many factors, including altered muscle protein turnover, diminished neuromuscular function, hormonal changes, systemic inflammation, and the structure and composition of muscle fibers, play a crucial role in age-related muscle decline. This study explored differences in muscle fiber types contributing to overall muscle function decline in aging, focusing on individuals with hip fractures from falls. A pilot study at Chungnam National University Hospital collected muscle biopsies from hip fracture patients aged 20 to 80 undergoing surgical treatment. Muscle biopsies from the vastus lateralis and gluteus maximus were obtained during hip arthroplasty or internal fixation. Handgrip strength, calf and thigh circumference, and bone mineral density were evaluated in individuals with hip fractures from falls. We analyzed the relationships between each clinical characteristic and muscle fiber type. In total, 26 participants (mean age 67.9 years, 69.2% male) were included in this study. The prevalence of sarcopenia was 53.8%, and that of femoral and lumbar osteoporosis was 19.2% and 11.5%, respectively. Vastus lateralis analysis revealed an age-related decrease in type IIx fibers, a higher proportion of type IIa fibers in women, and an association between handgrip strength and type IIx fibers in men. The gluteus maximus showed no significant correlations with clinical parameters. This study identified complex associations between age, sex, handgrip strength, and muscle fiber composition in hip fracture patients, offering insights crucial for targeted interventions combating age-related muscle decline and improving musculoskeletal health.

Proprietary alpha-amylase inhibitor formulation from white kidney bean (Phaseolus vulgaris L.) promotes weight and fat loss: a 12-week, double-blind, placebo-controlled, randomized trial

White kidney bean (Phaseolus vulgaris L.) extracts can aid weight management by reducing calorie intake from complex carbohydrates through alpha-amylase inhibition. We examined the impact of a proprietary aqueous extract from whole dried white kidney beans standardized by its alpha-amylase inhibitor activity (Phase 2 white kidney bean extract (WKBE)) on weight management in subjects with overweight and moderate obesity. In a randomized, double-blind, placebo-controlled fashion, 81 participants completed the study and ingested either a high dose of Phase 2 (1000 mg, WKBE HIGH), a low dose (700 mg, WKBE LOW), or a matching placebo (microcrystalline cellulose, PLA) three times a day, 30 min before meals, for 12 weeks during a calorie restricted diet. In a dose-dependent manner, Phase 2 significantly reduced body weight, fat mass, BMI, waist, hip and in the WKBE HIGH group thigh circumference. Phase 2 is an effective and safe supplement aiding weight and fat loss. ClinicalTrials.gov identifier NCT02930668.

Prevalence and factors associated with low functional mobility in older adults.

To analyze the factors associated with low functional mobility in older adults residing in Alcobaça, BA. This is an epidemiological survey with a cross-sectional design, conducted in 2015 with 473 older adults (62.4% women; mean age 70.2 ± 8.2 years) from Alcobaça, BA. The interview script addressed sociodemographic characteristics, health, and behavioral aspects. Functional mobility was assessed using the Short Physical Performance Battery (≤6 points). Inferential analyses were conducted using the Mann-Whitney U test and Poisson regression (with robust variance and estimation of prevalence ratios and their respective 95.0% confidence intervals). The prevalence of low functional mobility was 9.6%, with associated factors including the use of alcoholic beverages (PR = 1.7, 95% CI: 1.01-1.13) and the number of repetitions in elbow flexion (PR = 1.01, 95% CI: 1.01-1.05). Additionally, older adults with low mobility had lower height, thigh circumference, and lower performance in handgrip strength tests, elbow flexion, and flexibility. They also spent more time in sedentary behavior and less time in physical activity compared to older adults with preserved mobility (p < 0.05). Older adults with low mobility exhibit poorer values in anthropometric parameters, lower performance in motor tests, spend less time engaged in physical activities, and more time in sedentary behavior.

Measurement of arterial occlusion pressure using straight and curved blood flow restriction cuffs.

Arterial occlusion pressure (AOP) is influenced by the characteristics of the cuff used to measure AOP. Doppler ultrasound was used to measure AOP of the brachial and superficial femoral arteries using straight and curved blood flow restriction cuffs in 21 males and 21 females. Vessel diameter and blood flow were evaluated as independent predictors of AOP. Overall, there were no significant differences in AOP when using the straight and curved cuffs in the brachial (129 mmHg vs. 128 mmHg) or superficial femoral artery (202 mmHg vs. 200 mmHg), respectively. Overall, AOP was greater (p < 0.05) in males than in females in the arm (135 mmHg, 123 mmHg) and leg (211 mmHg, 191 mmHg). Brachial (0.376 mm, 0.323 mm) and superficial femoral (0.547 mm, 0.486 mm) arteries were larger (p = 0.016) in males than in females, respectively. Systolic blood pressure (SBP) and arm circumference were predictive of brachial artery AOP, whereas SBP, diastolic blood pressure, thigh circumference, and vessel diameter were predictive of superficial femoral artery AOP. Straight and curved cuffs are efficacious in the measurement of AOP in the arm and leg. Differences in vessel size may contribute to sex differences in AOP but this requires further investigation.

Multiethnic growth standards for fetal body composition and organ volumes derived from 3D ultrasonography

BackgroundA major goal of contemporary obstetrical practice is to optimize fetal growth and development throughout pregnancy. To date, fetal growth during prenatal care is assessed by performing ultrasonographic measurement of two-dimensional fetal biometry to calculate an estimated fetal weight. Our group previously established two-dimensional fetal growth standards using sonographic data from a large cohort with multiple sonograms. A separate objective of that investigation involved the collection of fetal volumes from the same cohort. ObjectiveThe Fetal 3D Study was designed to establish standards for fetal soft tissue and organ volume measurements by three-dimensional ultrasonography and compare growth trajectories with conventional two-dimensional measures where applicable. Study DesignThe NICHD Fetal 3D Study included research-quality images of singletons collected in a prospective, racially and ethnically diverse, low-risk cohort of pregnant individuals at 12 U.S. sites, with up to five scans per fetus (N=1,730 fetuses). Abdominal subcutaneous tissue thickness was measured from two-dimensional images and fetal limb soft tissue parameters extracted from three-dimensional multiplanar views. Cerebellar, lung, liver and kidney volumes were measured using virtual organ computer aided analysis (VOCAL). Fractional arm and thigh total volumes, and fractional lean limb volumes were measured, with fractional limb fat volume calculated by subtracting lean from total. For each measure, weighted curves (5th, 50th, 95th percentiles) were derived from 15-41 weeks’ using linear mixed models for repeated measures with cubic splines. ResultsSubcutaneous thickness of the abdomen, arm, and thigh increased linearly, with slight acceleration around 27-29 weeks. Fractional volumes of the arm, thigh, and lean limb volumes increased along a quadratic curvature, with acceleration around 29-30 weeks. In contrast, growth patterns for two-dimensional humerus and femur lengths demonstrated a logarithmic shape, with fastest growth in the 2nd trimester. The mid-arm area curve was similar in shape to fractional arm volume, with an acceleration around 30 weeks, whereas the curve for the lean arm area was more gradual. The abdominal area curve was similar to the mid-arm area curve with an acceleration around 29 weeks. The mid-thigh and lean area curves differed from the arm areas by exhibiting a deceleration at 39 weeks. The growth curves for the mid arm and thigh circumferences were more linear with some decelerations. Cerebellar two-dimensional diameter increased linearly, whereas cerebellar three-dimensional volume growth gradually accelerated until 32 weeks and then decelerated. Lung, kidney, and liver volumes all demonstrated gradual early growth followed by a linear acceleration beginning at 25 weeks for lungs, 26-27 weeks for kidneys, and 29 weeks for liver. ConclusionGrowth patterns and timing of maximal growth for three-dimensional lean and fat measures, limb and organ volumes differed from patterns revealed by traditional two-dimensional growth measures, suggesting these parameters reflect unique facets of fetal growth. Growth in these three-dimensional measures may be altered by genetic, nutritional, metabolic or environmental influences and pregnancy complications, in ways not identifiable using corresponding two-dimensional measures. Further investigation into the relationships of these three-dimensional standards to abnormal fetal growth, adverse perinatal outcomes, and health status in postnatal life is warranted.

The Contribution of Some Anthropometric Measurements and Pulmonary Volumes to The Digital achievement of the Sprint 400-meter Competition Among Elite Runners in Palestine

The study aimed to identify the contribution of some anthropometric measurements and pulmonary volumes to the digital achievement of the sprint 400-meter running distance among elite runners in Palestine. A total of 18 elite runners in Palestine, (age: 20.16+1.15 years; body mass: 67.75+5.04 kg; height: 173.11+6.01 m; body mass index (BMI):23.3 +3.1 kg/m2) were categorized as. Anthropometric measurements and Pulmonary volume measurements were taken (VC, FVC, FEV1, FWV1/FVC%, MVV, TV, RV, IC). The authors used Multiple linear Regression. Simple Linear Regression (T) and (Beta) to determine the regression line equation. It was determined that there was no statistically significant relationship between some anthropometric measurements (≤0.05). In order to determine the contribution of measurements chest circumference (r=*0.599), chest circumference (r=*0.573) in inspiration, thigh circumference (r=*0.773) calf (Gastrocnemius) muscle circumference(r=*0.554) it was determined that there was a statistically significant relationship between the digital success of the 400 meter sprint run. It was determined that there was no statistically significant relationship (α≤0.05) between lung volume measurements (FVC, FEV1, FWV1/FVC%, MVV). It was determined that there was no statistically significant relationship (α≤0.05) between lung volume measurements (FVC, FEV1, FWV1/FVC%, MVV). However, VC (p = 0.00); It was determined that there was a significant relationship in terms of (R2 = 0.616). In conclusin researchers recommend the necessity of using the predictive equations that have been developed as a predictor of digital achievement in the sprint 400-meter running competition.

The Effect of Contrast Therapy in Exercise Recovery: A Meta-Analytical Approach

Contrast therapy’s effects have varied across studies, necessitating an examination of its effect size. Therefore, this study aimed to validate the efficacy of contrast therapy on post-exercise recovery through a meta-analysis of exercise performance and physiological variables. Searches were conducted in electronic databases with the keywords "contrast therapy," "exercise performance," and "recovery”. Then articles were screened according to PRISMA guidelines. Fifteen articles were included in the meta-analysis. The results indicated significant differences in sprint (g=0.3811, p&amp;lt;.05), muscle soreness (g=0.7192, p&amp;lt;.01), perceived fatigue (g=0.7384, p&amp;lt;.01), and blood CK (g=0.7043, p&amp;lt;.05), demonstrating the effectiveness of contrast therapy compared to passive recovery. However, no significant differences were found in jump (g=0.0866, p=.7083), flexibility (g=0.0585, p=.7531), thigh circumference (g=0.1636, p=.5654), and perception of recovery (g=0.3254, p=.0661), although there was a slight trend favoring contrast therapy over passive recovery. Given this, contrast therapy could be beneficial for sports that involve frequent sprints or repeated high-intensity exercise with short rest periods. Additionally, considering psychological aspects like muscle soreness and perceived fatigue for optimal performance, we believe contrast therapy positively affects post-exercise recovery compared to passive recovery. However, the quality of the studies was low, and there were not as many studies that included contrast therapy for each dependent variable as expected. As more studies are conducted in the future, it is expected that a more in-depth analysis can be conducted by improving the quality of the literature and reflecting various results.

Peroneus Longus Tendon Autografts have Better Graft Diameter, Less Morbidity, and Enhanced Muscle Recuperation than Hamstring Tendon in ACL Reconstruction.

Recently the peroneus longus tendon (PLT) gained popularity in anterior cruciate ligament (ACL) reconstruction and has been utilized with satisfactory outcomes. However, there are concerns regarding donor site morbidity. This study aims to compare the functional outcome of ACL reconstruction using hamstring (HT) and PLT autografts and evaluate the donor site morbidity. Patients who underwent ACL reconstruction were allocated to two groups (HT and PLT). Graft diameter was measured intraoperatively. Knee functional outcome was evaluated with IKDC and Tegner-Lysholm scores preoperatively, and postoperatively after 3 months, 6 months, and 1 year. Donor site morbidities were assessed with thigh circumference measurements, subjective evaluation of sensory disturbances, and ankle scoring with AOFAS and FADI scores. At 1-year follow-up, the PLT group showed comparable IKDC (p = 0.925) and Tegner-Lysholm (p = 0.600) scores with those of the HT group. The mean graft diameter in the PLT group (7.93 ± 0.52mm) was larger compared with the HT group (7.43 ± 0.50mm) (p < 0.001). The incidence of thigh atrophy (HT-16.7%, PLT-10%) and sensory disturbances (HT-73.3%, PLT-10%) was greater in the HT group. There was no significant ankle donor site morbidity in the PLT group (AOFAS-98.67 ± 3.45, FADI-99.23 ± 1.69). ACL reconstruction with PLT had comparable functional outcome with that of HT at 1 year. However, PLT demonstrated larger graft diameter, less donor site morbidity, and enhanced muscle recovery without significantly affecting the ankle function. PLT can be safely used as an acceptable alternative graft choice harvested from outside the knee for ACL reconstruction.
