However, protein expression during the healing process remains a controversial issue. New Zealand rabbits, aged 14 weeks, underwent tenotomy followed immediately by Achilles tendon microsurgery to repair the Achilles tendon rupture. The tendon was then immobilized or subjected to postoperative early motion treatment (kinesitherapy). Mass spectrography results showed that after 14 days of motion treatment, 18 protein spots were differentially expressed, among which, 12 were up-regulated, consisting of gelsolin isoform b and neurite growth-related protein collapsing response mediator protein 2. Western blot analysis showed that gelsolin isoform b was up-regulated at days 7-21 of motion treatment. These findings suggest that active Achilles tendon kinesitherapy promotes the neurite regeneration of a ruptured Achilles tendon and gelsolin isoform b can be used as a biomarker for Achilles tendon healing after kinesitherapy.展开更多

High cardiorespiratory fitness is known to contribute to prevention of MetS. However, little is known regarding the association between muscular fitness and MetS in Japanese adults. The purpose of this study was to examine the associations between muscular fitness and MetS in Japanese women and men. This cross-sectional study included 335 women and 209 men aged 30 - 79 y. MetS was determined according to the 2009 criteria of the International Diabetes Federation. Muscular fitness was evaluated by muscular fitness composite score (MFS), which was determined using Z scores from grip strength and sit-ups. Participants were classified by MFS tertile into low, middle, and high MFS groups. We used multiple logistic regression analysis to estimate odds ratios for the incidence of MetS in each group. The prevalence of MFS was 27.2% in women and 27.3% in men. Adjusted odds ratios for MetS prevalence in the low, middle, and high MFS groups, after adjusting for age, smoking status, alcohol intake, and exercise habits, were 1.0 (referent), 0.90 (95% confidence interval [CI], 0.50 - 1.62), and 0.49 (95% CI, 0.25 - 0.94;P for trend = 0.03) in women;in men, they were 1.0 (referent), 0.49 (0.23 - 1.04), and 0.42 (0.18 - 0.97;P for trend = 0.04), respectively. Muscular fitness is inversely associated with the prevalence of MetS in Japanese women and men.展开更多

It has been found to be associated with the health and daily living status of people. Furthermore, an association between social capital and cognitive functions among the elderly has been suggested in recent years. However, the number of such reports is very few. Hence, the present study aims to evaluate the relationship between social capital and cognitive functions among the elderly living in a local community in Japan. A questionnaire survey was administered to 192 elderly individuals belonging to 10 neighborhood elderly groups. A regression analysis was conducted to determine the relationship between cognitive functions and the level of engagement with the local community, after adjusting for age, gender, and symptoms of depression. Valid responses were collected from 145 participants (mean age: 75.3 years). An analysis of the data concerning the level of engagement with the local community revealed a significant difference in the cognitive function scores between the group of people who indicated that they had someone they could consult (n = 69) and the group that indicated they had no one to consult (n = 76) (regression coefficient: -0.61, p = 0.0038, 95% confidence interval: -1.02 to -0.20). This result indicates the existence of a significant correlation between social capital and cognitive functions of the elderly living in a local community. In future studies, we need to investigate the same with a larger number of participants from a wider geographical area, and by incorporating more indicators for a comprehensive evaluation of social capital.展开更多

Subjects: 13 patients, 10 with medial, and 3 with lateral ligament injury. Methods: non-operative management consisted of employing a brace to prevent sagittal translation of the tibia. Quadriceps muscle and early passive knee motion exercises in the brace was encouraged immediately after arthroscopy. Weight-bearing was forbidden for 3 weeks. The brace was not removed for 3 months. Follow-up periods ranged from 2 to 6 years (mean, 3 years 2 months). Results: none, but one patient had a slight restriction of knee flexion. Quadriceps muscle strength revealed an average of 89.0% of normal side. The knee score indicated 2 patients rated good, 3 rated fair, and 8 rated poor. The score correlated with measurements of anterior and posterior translation on the stress radiograph significantly. Stress radiography revealed that anterior laxity was reduced better than posterior laxity significantly. Conclusion: non-operative brace therapy can be considered for this combined injury as the initial treatment. A late reconstruction would be performed when the result was not satisfactory. Preserved range of motion and muscle strength after brace therapy had a great advantage to the late reconstructive surgery.展开更多

Determining the extent of coronary luminal stenosis is a key factor in management of CAD. Methods presently used are costly and pose certain dangers, ranging from nephrotoxicity to death. Long Pentraxin or Pentraxin-3 (PTX3) has been used to predict survival or atherosclerotic process, but not to identify coronary stenosis. Calcium Score has been used to this end with some success. Methods: Individuals with chronic stable angina, without evidence of Myocardial Infarction (MI), who were categorized as intermediate-risk after completing a treadmill exercise test, according to Duke Protocol, underwent cardiac catheterization. In addition, blood samples were drawn for coronary sinus PTX3, and also PTX3, uric acid, high-sensitivity C-reactive protein (hs-CRP), cholesterol, glucose and High-Density Lipo-protein (HDL) in peripheral circulation. Calcium Scores were calculated using Agatston Score and non-contrast multi-slice CT scan. Participants were divided according to the number of stenotic coronary arteries (patent, one-, two-and three-vessel disease). Results: We found that PTX3 levels in coronary sinus and femoral vein correlated with each other, after log-transforming the values. Also we found that PTX3 levels and Calcium Scores differed among individuals with triple-vessel involvement and individuals without significant stenosis in any of coronary arteries. No significant differences were observed, regarding hs-CRP levels. Conclusion: PTX3 levels in periphery correlate with those in coronary arteries, and this variable can be measured with a less invasive procedure. In addition to Calcium Score, PTX3 levels are different in our four groups. The combined contribution of PTX3 and calcium score may help us identify individuals with significant coronary artery stenosis without needing to perform cardiac catheterization in a select group of patients.展开更多

文摘Active Achilles tendon kinesitherapy facilitates the functional recovery of a ruptured Achilles tendon. However, protein expression during the healing process remains a controversial issue. New Zealand rabbits, aged 14 weeks, underwent tenotomy followed immediately by Achilles tendon microsurgery to repair the Achilles tendon rupture. The tendon was then immobilized or subjected to postoperative early motion treatment (kinesitherapy). Mass spectrography results showed that after 14 days of motion treatment, 18 protein spots were differentially expressed, among which, 12 were up-regulated, consisting of gelsolin isoform b and neurite growth-related protein collapsing response mediator protein 2. Western blot analysis showed that gelsolin isoform b was up-regulated at days 7-21 of motion treatment. These findings suggest that active Achilles tendon kinesitherapy promotes the neurite regeneration of a ruptured Achilles tendon and gelsolin isoform b can be used as a biomarker for Achilles tendon healing after kinesitherapy.
文摘BACKGROUND Independent avulsion fractures with anterior cruciate ligament(ACL)or posterior cruciate ligament(PCL)attachment are relatively common among tibial intercondylar eminence fractures,and their postoperative outcomes are generally favorable.Conversely,huge avulsion fractures of the intercondylar eminence containing the attachment site of both the ACL and the PCL are extremely rare,and the reported clinical outcomes are poor.CASE SUMMARY We describe a 30-year-old Japanese male's huge avulsion fracture of the intercondylar eminence of a tibia containing the attachment site of both the ACL and PCL,together with a complete tear of the medial collateral ligament and a partial tear of both the medial and lateral menisci caused by a fall from a high place.All of these injuries were treated surgically,with anatomical reduction and stable fixation.The limb function at 1 year post-surgery was excellent(Lysholm score:100 points).CONCLUSION Although this patient's complete surgical repair was complex,it should be performed in similar cases for an excellent final clinical outcome.
文摘Background:Most papers examining the lateral abdominal muscles(LAMs)and low back pain(LBP)are cross-sectional,with groups of participants being divided into a control and an LBP group.We hypothesized that morphological measurements of the LAMs in adolescent soccer players may predict future LBP incidence.The aim of this study was to examine the associations between the morphology of LAMs and LBP incidence rate among adolescent soccer players.Methods:Ninety-seven adolescent male soccer players with no LBP at baseline were recruited into the prospective cohort study.The thickness of the LAMs was measured at baseline by ultrasound imaging in a supine rest position.Nine cases of LBP occurred during the follow-up 6-month observation.Results:An obliquus internus(OI)asymmetry was related to increasing LBP risk(odds ratio=19.99;95%CI:2.4-167.9).Spearman correlation also showed a linear relationship between OI asymmetry value and duration of LBP(R=0.75,p=0.02).An OI side-to-side difference greater than 1.25 mm suggests possible LBP incidence in the 6-month observation among adolescent soccer players.Conclusion:The morphological changes of the OI may be related to LBP’s incidence in adolescent soccer players.The presence of OI asymmetry increases the odds of LBP by at least 2.4 times.Hypertrophy of the OI on one side of the body may contribute to trunk muscle imbalance.

文摘Metabolic syndrome (MetS) is a complex interrelated risk factor for cardiovascular disease and type 2 diabetes mellitus. High cardiorespiratory fitness is known to contribute to prevention of MetS. However, little is known regarding the association between muscular fitness and MetS in Japanese adults. The purpose of this study was to examine the associations between muscular fitness and MetS in Japanese women and men. This cross-sectional study included 335 women and 209 men aged 30 - 79 y. MetS was determined according to the 2009 criteria of the International Diabetes Federation. Muscular fitness was evaluated by muscular fitness composite score (MFS), which was determined using Z scores from grip strength and sit-ups. Participants were classified by MFS tertile into low, middle, and high MFS groups. We used multiple logistic regression analysis to estimate odds ratios for the incidence of MetS in each group. The prevalence of MFS was 27.2% in women and 27.3% in men. Adjusted odds ratios for MetS prevalence in the low, middle, and high MFS groups, after adjusting for age, smoking status, alcohol intake, and exercise habits, were 1.0 (referent), 0.90 (95% confidence interval [CI], 0.50 - 1.62), and 0.49 (95% CI, 0.25 - 0.94;P for trend = 0.03) in women;in men, they were 1.0 (referent), 0.49 (0.23 - 1.04), and 0.42 (0.18 - 0.97;P for trend = 0.04), respectively. Muscular fitness is inversely associated with the prevalence of MetS in Japanese women and men.
文摘The concept of social capital encompasses all relationships and networks among people in a local community or society as a whole. It has been found to be associated with the health and daily living status of people. Furthermore, an association between social capital and cognitive functions among the elderly has been suggested in recent years. However, the number of such reports is very few. Hence, the present study aims to evaluate the relationship between social capital and cognitive functions among the elderly living in a local community in Japan. A questionnaire survey was administered to 192 elderly individuals belonging to 10 neighborhood elderly groups. A regression analysis was conducted to determine the relationship between cognitive functions and the level of engagement with the local community, after adjusting for age, gender, and symptoms of depression. Valid responses were collected from 145 participants (mean age: 75.3 years). An analysis of the data concerning the level of engagement with the local community revealed a significant difference in the cognitive function scores between the group of people who indicated that they had someone they could consult (n = 69) and the group that indicated they had no one to consult (n = 76) (regression coefficient: -0.61, p = 0.0038, 95% confidence interval: -1.02 to -0.20). This result indicates the existence of a significant correlation between social capital and cognitive functions of the elderly living in a local community. In future studies, we need to investigate the same with a larger number of participants from a wider geographical area, and by incorporating more indicators for a comprehensive evaluation of social capital.
文摘Introduction: results after non-operative management for knees sustaining combined acute anterior and posterior cruciate ligament tears were presented. Subjects: 13 patients, 10 with medial, and 3 with lateral ligament injury. Methods: non-operative management consisted of employing a brace to prevent sagittal translation of the tibia. Quadriceps muscle and early passive knee motion exercises in the brace was encouraged immediately after arthroscopy. Weight-bearing was forbidden for 3 weeks. The brace was not removed for 3 months. Follow-up periods ranged from 2 to 6 years (mean, 3 years 2 months). Results: none, but one patient had a slight restriction of knee flexion. Quadriceps muscle strength revealed an average of 89.0% of normal side. The knee score indicated 2 patients rated good, 3 rated fair, and 8 rated poor. The score correlated with measurements of anterior and posterior translation on the stress radiograph significantly. Stress radiography revealed that anterior laxity was reduced better than posterior laxity significantly. Conclusion: non-operative brace therapy can be considered for this combined injury as the initial treatment. A late reconstruction would be performed when the result was not satisfactory. Preserved range of motion and muscle strength after brace therapy had a great advantage to the late reconstructive surgery.
文摘Objective: Coronary Artery Disease (CAD) would continue to concern medical society in the foreseeable future. Determining the extent of coronary luminal stenosis is a key factor in management of CAD. Methods presently used are costly and pose certain dangers, ranging from nephrotoxicity to death. Long Pentraxin or Pentraxin-3 (PTX3) has been used to predict survival or atherosclerotic process, but not to identify coronary stenosis. Calcium Score has been used to this end with some success. Methods: Individuals with chronic stable angina, without evidence of Myocardial Infarction (MI), who were categorized as intermediate-risk after completing a treadmill exercise test, according to Duke Protocol, underwent cardiac catheterization. In addition, blood samples were drawn for coronary sinus PTX3, and also PTX3, uric acid, high-sensitivity C-reactive protein (hs-CRP), cholesterol, glucose and High-Density Lipo-protein (HDL) in peripheral circulation. Calcium Scores were calculated using Agatston Score and non-contrast multi-slice CT scan. Participants were divided according to the number of stenotic coronary arteries (patent, one-, two-and three-vessel disease). Results: We found that PTX3 levels in coronary sinus and femoral vein correlated with each other, after log-transforming the values. Also we found that PTX3 levels and Calcium Scores differed among individuals with triple-vessel involvement and individuals without significant stenosis in any of coronary arteries. No significant differences were observed, regarding hs-CRP levels. Conclusion: PTX3 levels in periphery correlate with those in coronary arteries, and this variable can be measured with a less invasive procedure. In addition to Calcium Score, PTX3 levels are different in our four groups. The combined contribution of PTX3 and calcium score may help us identify individuals with significant coronary artery stenosis without needing to perform cardiac catheterization in a select group of patients.

文摘MYBL2(MYB proto-oncogene like 2)is an emerging prognostic marker for malignant tumors,and its potential role in osteosarcoma and its relationship with immune infiltration in pan-cancer is yet to be elucidated.We constructed a transcription factor activity profile of os-teosarcoma using the single-cell regulatory network inference algorithm based on single-cell RNA sequencing data obtained from the Gene Expression Omnibus.Subsequently,we calcu-lated the extent of MYBL2 activation in malignant proliferative osteoblasts.We also explored the association between MYBL2 and chemotherapy resistance in osteosarcoma.Furthermore,we systematically correlated MYBL2 with immunological signatures in the tumor microenviron-ment in pan-cancer,including immune cell infiltration,immune checkpoints,and tumor immu-notherapy prognosis.Finally,we developed and validated a risk score(MRGS),derived an osteosarcoma risk score nomogram based on MRGS,and tested its ability to predict prognosis.MYBL2 and gene enrichment analyses in osteosarcoma and pan-cancer revealed that MYBL2 was positively correlated with cell proliferation and tumor immune pathways.MYBL2 expres-sion positively correlated with SLC19A1 in pan-cancer and osteosarcoma cell lines.Pan-cancer immune infiltration analysis revealed that MYBL2 was correlated with myeloid-derived sup-pressor cells,Th2 cell infiltration,CD276,RELT gene expression,and tumor mutation burden.

文摘Purpose:To identify risk factors for developing pressure ulcers(PUs)in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries(SCIs).Methods:Data were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran(NSCIR-IR)from individuals with traumatic spinal fractures with or without SCIs,in-clusive of the hospital stay from admission to discharge.Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay.The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification.In addition to PU,following data were also extracted from the NSCIR-IR datasets during the period of 2015-2021:age,sex,Glasgow coma scale score at admission,having SCIs,marital status,surgery for a spinal fracture,American Spinal Injury Association impairment scale(AIS),urinary incontinence,level of education,admitted center,length of stay in the intensive care unit(ICU),hypertension,respiratory diseases,consumption of ciga-rettes,diabetes mellitus and length of stay in the hospital.Logistic regression models were used to es-timate the unadjusted and adjusted odds ratio(OR)with 95%confidence intervals(CI).Results:Altogether 2785 participants with traumatic spinal fractures were included.Among them,87(3.1%)developed PU during their hospital stay and 392(14.1%)had SCIs.In the SCI population,63(16.1%)developed PU during hospital stay.Univariate logistic regression for the whole sample showed that marital status,having SCIs,urinary incontinence,level of education,treating center,number of days in the ICU,age,and Glasgow coma scale score were significant predictors for PUs.However,further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center,marital status,having SCIs,and the number of days in the ICU.For the subgroup of individuals with SCIs,marital status,AIS,urinary incontinence,level of education,the treating center,the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis.After adjustment in the multivariate model,the treating center,marital status(singles vs.marrieds,OR=3.06,95%CI:1.55-6.03,p=0.001),and number of days in the ICU(OR=1.06,95%Cl:1.04-1.09,p<0.001)maintained significance.Conclusions:These data confirm that individuals with traumatic spinal fractures and SCIs,especially single young patients who suffer from urinary incontinence,grades A-D by AIS,prolonged ICU stay,and more extended hospitalization are at increased risk for PUs;as a result strategies to minimize PU development need further refinement.
