Low Bone Mineral Density as a Predictor of Mortality and Infections in Stroke Patients: A Hospital-based Study.

CONTEXT: Low bone mineral density (BMD) has been linked to elevated risks of mortality and infections in the general population; however, its association with these outcomes in stroke patients remains unclear. OBJECTIVE: This study aims to investigate the correlation between low BMD and risks of mortality and infections among stroke patients in a Taiwanese cohort. METHODS: In this single-centered retrospective cohort study, 905 stroke patients from a Taiwanese database (2000-2022) were analyzed. Patients were divided based on BMD measurements of the femur and spine. The primary outcome was all-cause mortality, and secondary outcomes included urinary tract infection (UTI) and pneumonia. Accelerated failure time regression model analyses evaluated the association between BMD and these outcomes, while the Kaplan-Meier method and log-rank test assessed survival differences between groups. RESULTS: Among the participants (average age 76.1 years, 70.5% female), 33.82% had osteopenia and 55.25% had osteoporosis. Stroke patients with lower spine and right femur BMD had significantly reduced survival rates, especially when the BMD value fell below 0.842 g/cm2 (spine), and 0.624 g/cm2 (right femur), respectively. Regarding secondary outcomes, lower spine BMD was significantly associated with an increased risk of UTI. CONCLUSION: Low BMD, particularly in the femur and spine, is a significant predictor of mortality and UTI in stroke patients. These findings highlight the importance of assessing and managing BMD in stroke patients to improve outcomes and reduce complications.

Development of Wearable Devices for Collecting Digital Rehabilitation/Fitness Data from Lower Limbs.

Lower extremity exercises are considered a standard and necessary treatment for rehabilitation and a well-rounded fitness routine, which builds strength, flexibility, and balance. The efficacy of rehabilitation programs hinges on meticulous monitoring of both adherence to home exercise routines and the quality of performance. However, in a home environment, patients often tend to inaccurately report the number of exercises performed and overlook the correctness of their rehabilitation motions, lacking quantifiable and systematic standards, thus impeding the recovery process. To address these challenges, there is a crucial need for a lightweight, unbiased, cost-effective, and objective wearable motion capture (Mocap) system designed for monitoring and evaluating home-based rehabilitation/fitness programs. This paper focuses on the development of such a system to gather exercise data into usable metrics. Five radio frequency (RF) inertial measurement unit (IMU) devices (RF-IMUs) were developed and strategically placed on calves, thighs, and abdomens. A two-layer long short-term memory (LSTM) model was used for fitness activity recognition (FAR) with an average accuracy of 97.4%. An intelligent smartphone algorithm was developed to track motion, recognize activity, and calculate key exercise variables in real time for squat, high knees, and lunge exercises. Additionally, a 3D avatar on the smartphone App allows users to observe and track their progress in real time or by replaying their exercise motions. A dynamic time warping (DTW) algorithm was also integrated into the system for scoring the similarity in two motions. The system's adaptability shows promise for applications in medical rehabilitation and sports.

Isokinetic training of lower extremity during the early stage promote functional restoration in elder patients with disability after Total knee replacement (TKR) - a randomized control trial.

BACKGROUND: Transient progressive weakness and disability of lower limb during the early stage after TKR will increase the risk of fall, but the superior postoperative strength training mode have not been elucidated for functional restoration. This study aimed to compare whether the isokinetic lower limb training is superior to either isotonic or home isometric exercise during early stage after TKR in older people. METHODS: A total of 43 recruited old participants (mean age, 68.40 years old) receiving TKR were divided randomly based on the different four-week training modes into three groups including isokinetic, isotonic, and home isometric exercise (control group). The primary outcome was set as functional performance in terms of Timed Up and Go (TUG) test and the secondary outcomes include the peak torque of knee at 60 and 120 degree/ second, Short-Form 36 Health Survey (SF-36), and Western Ontario and McMaster Universities Arthritis index (WOMAC). RESULTS: All of the peak torque measurements of the knee improved significantly in both the isokinetic and the isotonic group, but not in the control group. Although isotonic training resulted in more strength gains, a significant enhancement in TUG test was observed in the isokinetic group only (p = 0.003). However, there were no significantly improvement of TUG test after training in other two groups. SF-36 and WOMAC improved after training in all three groups, with no significant difference in the degree of improvement between groups. CONCLUSION: Isokinetic training for 4 weeks following TKR effectively improved all the outcome parameters in this study, including the TUG test, lower limb strength, and functional scores. However, both isokinetic and isotonic training modes could be recommended after TKR because of no significant difference in the degree of improvement between these two groups.

Effects of soft robotic exosuit on ambulation ability in stroke patients: a systematic review.

BACKGROUND: Robot-assisted gait training is incorporated into guidelines for stroke rehabilitation. It is a promising tool combined with conventional therapy for low ambulatory patients. The heavy weight and bulky appearance of a robotic exoskeleton limits its practicality. On the other hand, soft robotic exosuit (SRE) based on its light weight and inconspicuous property, is better tolerated by patients in daily life. The aim of this study is to review the efficacy of the SRE with regard to walking ability and biomechanical properties in stroke patients. METHODS: Electronic searches were carried out in PubMed, Embase, Cochrane Library, Web of Science, and the Physiotherapy Evidence Database. Clinical trials that investigated the effectiveness of SREs on ambulation ability in patients with post-stroke hemiparesis were eligible. Qualitative data synthesis was subsequently performed. RESULTS: Nine studies were identified as relevant, involving a total of 83 patients. For the assessment of SRE efficacy, outcome measures were walking ability and biomechanical properties. In terms of both immediate effect and training effect, SREs improved the walking speed, walking distance, peak ankle dorsiflexion angle during swing phase, peak paretic propulsion, stride length and compensated gait in stroke patients. CONCLUSIONS: SRE improved the ambulation ability of stroke patients in terms of walking ability and biomechanical properties. The small number of studies limits the generalizability of interpretation. More controlled studies with better quality are required to reach a more solid conclusion on this issue.

Feasibility of Aerobic Exercise Training to Mitigate Cardiotoxicity of Breast Cancer Therapy: A Systematic Review and Meta-Analysis.

BACKGROUND: Current anticancer treatments for breast cancer (BC) may cause cardiotoxicity. This study aimed to investigate the effectiveness of aerobic exercise in mitigating cardiotoxicity caused by BC therapy. MATERIALS AND METHODS: PubMed, Embase, Cochrane Library, Web of Science, and the Physiotherapy Evidence Database were searched until February 7, 2023. Clinical trials investigating the effectiveness of exercise training, including aerobic exercise, in BC patients receiving treatments that could cause cardiotoxicity were eligible. Outcome measures included cardiorespiratory fitness (CRF) (peak oxygen consumption, VO2peak), left ventricular ejection fraction, and peak oxygen pulse. Intergroup differences were determined by standard mean differences (SMD) and 95% confidence intervals (CIs). Trial sequential analysis (TSA) was utilized to ensure whether the current evidence was conclusive. RESULTS: Sixteen trials involving 876 participants were included. Aerobic exercise significantly improved CRF measured by VO2peak in mL/kg/min (SMD 1.79, 95% CI 0.99-2.59) when compared to usual care. This result was confirmed through TSA. Subgroup analyses revealed that aerobic exercise given during BC therapy significantly improved VO2peak (SMD 1.84, 95% CI 0.74-2.94). Exercise prescriptions at a frequency of up to 3 times per week, an intensity of moderate to vigorous, and a >30-minute session length also improved VO2peak. CONCLUSION: Aerobic exercise is effective in improving CRF when compared to usual care. Exercise performed up to 3 times per week, at a moderate-to-vigorous intensity, and having a session length >30 minutes is considered effective. Future high-quality research is needed to determine the effectiveness of exercise intervention in preventing cardiotoxicity caused by BC therapy.

The Application of Soft Robotic Gloves in Stroke Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Wearable robotic devices have been strongly put into use in both the clinical and research fields of stroke rehabilitation over the past decades. This study aimed to explore the effectiveness of soft robotic gloves (SRGs) towards improving the motor recovery and functional abilities in patients with post-stroke hemiparesis. Five major bibliographic databases, PubMed, Embase, Cochrane Library, Web of Science, and the Physiotherapy Evidence Database, were all reviewed for enrollment regarding comparative trials prior to 7 March 2023. We included adults with stroke and compared their rehabilitation using SRGs to conventional rehabilitation (CR) on hand function in terms of the Fugl-Meyer Upper Extremity Motor Assessment (FMA-UE), Fugl-Meyer Distal Upper Extremity Motor Assessment (FMA-distal UE), box and blocks test score, grip strength test, and the Jebsen-Taylor hand function test (JTT). A total of 8 studies, comprising 309 participants, were included in the analysis. Compared to CR, rehabilitation involving SRGs achieved better FMA-UE (MD 6.52, 95% CI: 3.65~9.39), FMA-distal UE (MD 3.27, 95% CI: 1.50~5.04), and JJT (MD 13.34, CI: 5.16~21.53) results. Subgroup analysis showed that stroke latency of more than 6 months and training for more than 30 min offered a better effect as well. In conclusion, for patients with stroke, rehabilitation using SRGs is recommended to promote the functional abilities of the upper extremities.

Therapeutic Effects of Robotic-Exoskeleton-Assisted Gait Rehabilitation and Predictive Factors of Significant Improvements in Stroke Patients: A Randomized Controlled Trial.

Robotic-exoskeleton-assisted gait rehabilitation improves lower limb strength and functions in post-stroke patients. However, the predicting factors of significant improvement are unclear. We recruited 38 post-stroke hemiparetic patients whose stroke onsets were <6 months. They were randomly assigned to two groups: a control group receiving a regular rehabilitation program, and an experimental group receiving in addition a robotic exoskeletal rehabilitation component. After 4 weeks of training, both groups showed significant improvement in the strength and functions of their lower limbs, as well as health-related quality of life. However, the experimental group showed significantly better improvement in the following aspects: knee flexion torque at 60°/s, 6 min walk test distance, and the mental subdomain and the total score on a 12-item Short Form Survey (SF-12). Further logistic regression analyses showed that robotic training was the best predictor of a greater improvement in both the 6 min walk test and the total score on the SF-12. In conclusion, robotic-exoskeleton-assisted gait rehabilitation improved lower limb strength, motor performance, walking speed, and quality of life in these stroke patients.

Frontoparietal Dysconnection in Covert Bipedal Activity for Enhancing the Performance of the Motor Preparation-Based Brain-Computer Interface.

Motor-based brain-computer interfaces (BCIs) were developed from the brain signals during motor imagery (MI), motor preparation (MP), and motor execution (ME). Motor-based BCIs provide an active rehabilitation scheme for post-stroke patients. However, BCI based solely on MP was rarely investigated. Since MP is the precedence phase before MI or ME, MP-BCI could potentially detect brain commands at an earlier state. This study proposes a bipedal MP-BCI system, which is actuated by the reduction in frontoparietal connectivity strength. Three substudies, including bipedal classification, neurofeedback, and post-stroke analysis, were performed to validate the performance of our proposed model. In bipedal classification, functional connectivity was extracted by Pearson's correlation model from electroencephalogram (EEG) signals recorded while the subjects were performing MP and MI. The binary classification of MP achieved short-lived peak accuracy of 73.73(±7.99)% around 200-400 ms post-cue. The peak accuracy was found synchronized to the MP-related potential and the decrement in frontoparietal connection strength. The connection strengths of the right frontal and left parietal lobes in the alpha range were found negatively correlated to the classification accuracy. In the subjective neurofeedback study, the majority of subjects reported that motor preparation instead of the motor imagery activated the frontoparietal dysconnection. Post-stroke study also showed that patients exhibit lower frontoparietal connections compared to healthy subjects during both MP and ME phases. These findings suggest that MP reduced alpha band functional frontoparietal connectivity and the EEG signatures of left and right foot MP could be discriminated more effectively during this phase. A neurofeedback paradigm based on the frontoparietal network could also be utilized to evaluate post-stroke rehabilitation training.

Benefits of Cycling Wheelchair Training for Elderly with Physical Disability: A Prospective Cohort Study.

AIM: In order to investigate the effect of cycling wheelchair training as an exercise for aged 65+ disabled patients on cognitive function, quality of life, aerobic capacity and physiological parameters. METHODS: Participants in nursing home performed cycling wheelchair training for 30 min a day, 5 days a week, for a total of 4 weeks. The main outcome measure was the short form 12 survey (SF-12). Other outcome measures included the Mini-Mental State Examination (MMSE), aero bike work rate test, resting blood pressure, and heart rate. RESULTS: In this study, 41 volunteers were recruited and no participants dropped out of the study voluntarily during training, and no serious adverse effect was identified. Physical and mental component summary total scores of SF-12 were significantly higher after training with statistical significance (p = 0.001). 8 subscales also showed significant improvements after training (p = 0.025 ~ <0.001). Total MMSE score has no difference before and after training. Attention/calculation (p = 0.018), short term memory (p = 0.041), and aerobic capacity (p < 0.001) as measured by subscales of MMSE and aero bike test showed marked improvements, while resting systolic blood pressure (p = 0.931) and heart rate (p = 0.793) did not change. CONCLUSIONS: Cycling wheelchair is practical for the disabled elderly to exercise, and a 4-week exercise program enhanced their quality of life and aerobic capacity.

Predictors of Basic Activity in Daily Living and Length of Hospitalization in Patients with COVID-19.

BACKGROUND: Patients recovered from COVID-19 often suffer from the sequelae of the disease, which can hinder the patients' activity in daily living. Early recognition of the patients at risk of prolonged hospitalization and impaired physical functioning is crucial for early intervention. We aim to identify the predictors of prolonged hospitalization and impaired activity in daily living in this study. METHODS: COVID-19 patients hospitalized in a medical center were divided into two groups according to the Barthel index three months after discharge and the median length of hospital stay, respectively. Chi-square test and Mann-Whitney U test were performed to check the differences between the two groups in patient characteristics as well as hematology tests at the emergency department, the intensive care unit mobility scale (ICUMS), and the medical research council sum score (MRCSS). Logistic regression and the receiver operating characteristic curve analysis were further performed for the factors with significant differences between the two groups. RESULTS: Both ICUMS and MRCSS showed significant differences between the groups. The ICUMS had an odds ratio of 0.61 and the MRCSS of 0.93 in predicting a Barthel index score less than 100 three months after discharge. The MRCSS had an odds ratio of 0.82 in predicting a prolonged length of hospital stay. CONCLUSION: Both ICUMS and MRCSS upon admission are predictive of a Barthel index score of less than 100 three months after discharge. On the other hand, only MRCSS has predictive value of a prolonged hospitalization.

The Adjuvant Therapy of Intravenous Laser Irradiation of Blood (ILIB) on Pain and Sleep Disturbance of Musculoskeletal Disorders.

(1) Background: Musculoskeletal pain is both intractable and irritating. Intravenous Laser Irradiation of Blood (ILIB) therapy has been used as pain control treatment for this condition. However, there remains a lack of clear evidence regarding ILIB on pain control. This study aimed to reveal the result of changes in patient pain intensity after receiving ILIB therapy. (2) Methods: We conducted a retrospective analysis of pain scores and sleep quality from 76 patients diagnosed with musculoskeletal disease who received three courses of ILIB therapy. Each course included ten sessions of ILIB treatment over ten consecutive days. During ILIB therapy, patients were inserted with a laser fiber optic needle which irradiated blood cells via a 632.8 nm Helium-Neon laser light over a period of 60 min. Pain scores were evaluated using the Visual Analogue Scale (VAS), whereas sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). These scores would be recorded both before and after each ILIB treatment course. (3) Results: The mean of all patients' initial VAS score was 5.35. After completing three courses of ILIB treatment, the mean VAS score decreased to 2.2, which indicated a significant reduction in pain intensity. Additionally, patients experienced sleep quality improvement levels from PSQI 8.97 to 5.53 upon completion of three courses of ILIB treatment. (4) Conclusions: Intravenous Laser Irradiation of Blood (ILIB) resulted in a positive pain control effect on patients with musculoskeletal disease, especially for those with moderate to severe pain intensity (initial VAS score >4). Additionally, patients experienced better sleep quality as a result of their pain relief after receiving ILIB treatment.

Guillain-Barré Syndrome with Respiratory Failure following Spine Surgery for Incomplete Cervical Cord Injury: A Case Report and Literature Review.

Guillain-Barré syndrome (GBS) often develops after a respiratory or gastrointestinal infection. A few cases have been reported on GBS following elective spinal surgery not preceded by an infectious disease. In patients with underlying upper motor neuron disease such as a spinal cord injury, concurrent development of lower motor neuron diseases, such as GBS, could be overlooked. Here, we present an uncommon case of an 87-year-old man with GBS that had developed after an operation for a traumatic cervical spinal cord injury. After surgery, he showed weakness over all four limbs with paresthesia, but he was able to hold a standing position with minimal assistance. Unfortunately, his muscle strength over his four limbs gradually weakened from two to four weeks later, and he became almost completely paralyzed. Cerebrospinal fluid (CSF) studies revealed albuminocytologic dissociation. A nerve conduction study (NCS) indicated an acute axonal polyneuropathy superimposed on chronic sensorimotor polyneuropathy. Thus, the patient was diagnosed with GBS. However, the patient's family declined immune-modulatory therapy due to personal reasons. The patient progressed into respiratory failure and remained ventilator-dependent before his death three years later. This case highlights the importance of taking GBS into account when postoperative weakness occurs in patients with spinal cord injury, and a worse prognosis if GBS is left untreated.

Effectiveness of home-based telerehabilitation programs on functional capacity and cardiac function in elderly heart failure patients: A prospective longitudinal study.

Decreased functional capacity and reduced cardiac function were the main symptoms in patients with heart failure (HF) and the incidence increases with advanced age. The guidelines recommend that exercise training should be considered for medically stable HF outpatients. Studies have confirmed that exercise can improve functional capacity, prognosis, and reduced hospitalization rates; however, very few studies have investigated the elderly. It is not clear whether exercise could be feasible in elderly HF. The aim of this study was to evaluate the effect of the 6-month heart failure post-acute care program focused on home-based cardiac telerehabilitation (HCTR) on functional capacity, cardiac function, and readmission rates in HF patients. A prospective longitudinal study was conducted. Study duration was from January 2018 to December 2019. HF patients with a left ventricular ejection fraction <40% and age ≧65 years were included and divided into intervention (n = 40) and control group (n = 41). We arranged a 6-month heart failure post-acute care program that included outpatient cardiac rehabilitation and home exercise for the intervention group. The response to home exercise was followed by telemonitor. The exercise parameters were recorded on the HF health management mobile application system platform by each patient and daily transmission to hospital's cloud database as HCTR, usual care program for the control group. Information such as general data, laboratory data, six-minute walk test, cardiac function, and admission record was collected from all patients. Eighty one patients between the ages of 65 and 92 completed the study. The mean age was 73.3 ± 5.0 and 75.6 ± 6.0 years in control and intervention group, respectively. The intervention group showed a statistically significant improvement in functional capacity, percentage change in the of six-minute walk distance (51.2% vs 17.7%, P < .05, 95% confidence interval -45.9 to -6.3). Left ventricular ejection fraction increased by 7.7%, which corresponds to 25.6% in relative terms (P < .05, 95% confidence interval -7.8 to -0.5). The readmission rate was 4.6% in the intervention group. Six months of post-acute HF focused on HCTR programs was safe, improved functional capacity, cardiac function, and decreased readmission rate in elderly patients with HF patients.

Comparison of the Therapeutic Effects Between Isokinetic and Isotonic Strength Training in Patients After Total Knee Replacement: A Prospective, Randomized Controlled Trial.

Background: Rebuilding the strength of the quadriceps as soon as possible after total knee replacement (TKR) is important so as to restore gait stability. To date, there are no standard postoperative strength training programs during the early recovery stage after TKR. Purpose: To compare the therapeutic effects between isokinetic and isotonic strengthening in patients after TKR. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: From April 2018 to August 2020, 37 patients met the inclusion criteria and were randomly assigned to perform either 4-week isokinetic or isotonic strength training programs. Other components of the rehabilitation program were kept the same between the 2 groups. All cases were evaluated by the Timed Up and Go (TUG) test, peak torque of knee extension and flexion (60 and 120 deg/s), 36-item Short Form Health Survey (SF-36), and Western Ontario and McMaster Universities Arthritis Index (WOMAC). Results: After undergoing a 4-week strength training regimen, significant improvements in the TUG test were noted in both groups; however, the time improvement in the isotonic group did not reach the minimal detectable change. All peak torque measurements improved in the isokinetic group but not in the isotonic group for knee flexion at 60 deg/s. The pain subdomain, physical domain, mental domain, total SF-36 score, and WOMAC index all improved significantly in both groups after training. Both training groups improved significantly in peak torque of knee strength, TUG test, and functional scores, but the differences between isokinetic and isotonic training were not statistically significant. Conclusion: The study findings showed that a 4-week strengthening exercise program in the early postoperative stage, involving either isokinetic or isotonic training, resulted in significant improvements in patients undergoing TKR. Registration: NCT02938416 (ClinicalTrials.gov identifier).

Therapeutic Effects of Intradialytic Exercise on Life Quality of Patients with End-Stage Renal Disease: Study Protocol for a Randomized Control Trial.

BACKGROUND: Exercise training has positive effects on physical functions and could reduce a sedentary lifestyle for hemodialysis (HD) patients. Given that low-level physical activity increases morbidity and mortality, here, we aimed to determine the effects of an intradialytic exercise program delivered at different frequencies on HD patients in Taiwan. METHODS: This study is a prospective, randomized control trial. An intradialytic exercise program will be arranged for patients after receiving their informed consent. Patients will be segregated at random into three groups as follows: (a) three times/week of intradialytic exercise training plus standard care maintenance of HD, (b) two times/week of intradialytic exercise training plus standard care maintenance of HD, or (c) standard care maintenance of HD. Subjects will be followed for 24 weeks. At three time points, 0, 12, and 24 weeks, the primary outcome, the Short-Form 36 score, will be measured. Additional secondary outcomes to be measured are the Beck depression inventory, 6 min walking test, sit-to-stand test, and anthropometric measures such as the body mass index, thigh circumference, and the proportion of fat in the body composition. CONCLUSIONS: There is emerging evidence in support of intradialytic exercise improving health-related quality of life for patients on HD. However, the difference in the therapeutic effects between three times per week and twice per week has never been determined. With this study, we anticipate to fill the knowledge gap in the exercise prescription among HD patients.

Respiratory Muscle Training Can Improve Cognition, Lung Function, and Diaphragmatic Thickness Fraction in Male and Non-Obese Patients with Chronic Obstructive Pulmonary Disease: A Prospective Study.

Patients with chronic obstructive pulmonary disease (COPD) are frequently comorbid with mild cognitive impairment (MCI). Whether respiratory muscle training (RMT) is helpful for patients with COPD comorbid MCI remains unclear. Inspiratory muscle training (IMT) with or without expiratory muscle training (EMT) was performed. Patients were randomly assigned to the full training group (EMT + IMT) or the simple training group (IMT only). A total of 49 patients completed the eight-week course of RMT training. RMT significantly improved the maximal inspiratory pressure (MIP), the diaphragmatic thickness fraction and excursion, lung function, scores in the COPD assessment test (CAT), modified Medical Research Council (mMRC) scale scores, and MMSE. The between-group difference in the full training and single training group was not significant. Subgroup analysis classified by the forced expiratory volume in one second (FEV1) level of patients showed no significant differences in MIP, lung function, cognitive function, and walking distance. However, a significant increase in diaphragmatic thickness was found in patients with FEV1 ≥ 30%. We suggest that patients with COPD should start RMT earlier in their disease course to improve physical activity.

Extracorporeal Shock Wave Therapy Combined with Complex Decongestive Therapy in Patients with Breast Cancer-Related Lymphedema: A Systemic Review and Meta-Analysis.

Breast cancer-related lymphedema (BCRL) is one of the most significant complications seen after surgery. Several studies demonstrated that extracorporeal shock wave therapy (ESWT), in addition to conventional complex decongestive therapy (CDT), had a positive effect on BCRL in various aspects. The systematic review and meta-analysis aim to explore the effectiveness of ESWT with or without CDT on BRCL patients. We searched PubMed, Embase, PEDro, Cochrane Library Databases, and Google Scholar for eligible articles and used PRISMA2020 for paper selection. Included studies were assessed by the PEDro score, Modified Jadad scale, STROBE assessment, and GRADE framework for the risk of bias evaluation. The primary outcomes were the volume of lymphedema and arm circumference. Secondary outcome measures were skin thickness, shoulder joint range of motion (ROM), and an impact on quality-of-life questionnaire. Studies were meta-analyzed with the mean difference (MD). Eight studies were included in the systemic review and four in the meta-analysis. In summary, we found that adjunctive ESWT may significantly improve the volume of lymphedema (MD = -76.44; 95% CI: -93.21, -59.68; p < 0.00001), skin thickness (MD = -1.65; 95% CI: -3.27, -0.02; p = 0.05), and shoulder ROM (MD = 7.03; 95% CI: 4.42, 9.64; p < 0.00001). The evidence level was very low upon GRADE appraisal. ESWT combined with CDT could significantly improve the volume of lymphedema, skin thickness, and shoulder ROM in patients with BCRL. There is not enough evidence to support the use of ESWT as a replacement for CDT. This study was registered with PROSPERO: CRD42021277110.

Enhanced Platelet-Rich Plasma (ePRP) Stimulates Wound Healing through Effects on Metabolic Reprogramming in Fibroblasts.

As a source of growth factors for expediting wound healing and tissue regeneration, plasma-rich plasma (PRP) has been extensively applied in diverse fields including orthopaedics, ophthalmology, oral and maxillofacial surgery, dentistry, and gynaecology. However, the function of PRP in metabolic regulations remains enigmatic. A standardized method was devised herein to enrich growth factors and to lyophilize it as enhanced PRP (ePRP) powder, which could become ubiquitously available without mechanical centrifugation in clinical practice. To identify metabolic reprogramming in human dermal fibroblasts under ePRP treatment, putative metabolic targets were identified by transcriptome profiling and validated for their metabolic effects and mechanism. ePRP does not only promote wound healing but re-aligns energy metabolism by shifting to glycolysis through stimulation of glycolytic enzyme activity in fibroblasts. On the contrary, oxygen consumption rates and several mitochondrial respiration activities were attenuated in ePRP-treated fibroblasts. Furthermore, ePRP treatment drives the mitochondrial resetting by hindering the mitochondrial biogenesis-related genes and results in a dampened mitochondrial mass. Antioxidant production was further increased by ePRP treatment to prevent reactive oxygen species formation. Besides, ePRP also halts the senescence progression of fibroblasts by activating SIRT1 expression. Importantly, the glycolytic inhibitor 2-DG can completely reverse the ePRP-enhanced wound healing capacity, whereas the mitochondrial inhibitor oligomycin cannot. This is the first study to utilize PRP for comprehensively investigating its effects on the metabolic reprogramming of fibroblasts. These findings indicate that PRP's primary metabolic regulation is to promote metabolic reprogramming toward glycolytic energy metabolism in fibroblasts, preserving redox equilibrium and allowing anabolic pathways necessary for the healing and anti-ageing process.

Increased risk of stroke in patients with diffuse idiopathic skeletal hyperostosis: a nationwide population-based cohort study.

Diffuse idiopathic skeletal hyperostosis (DISH) is frequently an incidental finding during X-ray examination. Although it has been shown to be associated with several chronic diseases, the hazard of cerebrovascular disease has seldom been explored. Our study aimed at determining the risk of stroke conferred by DISH, which is a retrospective cohort study adopting the largest medical database in Taiwan. Patients with a diagnosis of DISH at least three times from 2005 to 2010 were identified as the study group, and those in the control group were selected by matching age and gender. Patients were followed up until the end of 2015 to trace the incidence of stroke. Cox regression analysis was performed to compute the hazard ratio of stroke. Among the included 5300 patients, 1060 had a diagnosis of DISH. Significantly higher prevalence rates of stroke, hypertension, diabetes, and hyperlipidemia were noted in these patients. Overall, DISH conferred a 1.68 times higher risk of developing stroke. The significantly higher hazard ratio could be identified in both genders whether hypertension existed or not. Even in those without comorbidities, DISH still conferred a significantly higher risk of cerebrovascular disease in the future, which should never be ignored when encountered during clinical practice.

Effects of intravascular laser phototherapy on delayed neurological sequelae after carbon monoxide intoxication as evaluated by brain perfusion imaging: A case report and review of the literature.

BACKGROUND: Delayed neurological sequelae (DNS) caused by carbon monoxide (CO) intoxication poses considerable treatment challenges for clinical practitioners. In this report, we used nuclear medicine imaging and the Mini-Mental State Examination (MMSE) to evaluate the effectiveness of intravascular laser irradiation of blood (ILIB) therapy for the management of DNS. CASE SUMMARY: A 51-year-old woman presented to our medical center experiencing progressive bradykinesia, rigidity of limbs, gait disturbance, and cognitive impairment. Based on her neurological deficits, laboratory tests and imaging findings, the patient was diagnosed with delayed neurological sequelae of CO intoxication. She received intensive rehabilitation and ILIB therapy during 30 sessions over 2 mo after diagnosis. Brain single-photon emission computed tomography was performed both prior to and after ILIB therapy. The original hypoperfusion area in bilateral striata, bilateral frontal lobe, right parietal lobe, and bilateral cerebellum showed considerable improvement after completion of therapy. The patient's MMSE score also increased markedly from 6/30 to 25/30. Symptoms of DNS became barely detectable, and the woman was able to carry out her daily living activities independently. CONCLUSION: ILIB therapy could facilitate recovery from delayed neurological sequelae in patients with CO intoxication, as demonstrated by improved cerebral blood flow and functional outcomes in our patient.
