Effects of low-level laser therapy on symptomatic calcific rotator cuff tendinopathy : A prospective randomized controlled study.

OBJECTIVE: Rotator cuff calcific tendinitis (RCCT) is a benign but incapacitating condition and in some patients it is the cause of chronic debilitating pain and functional disability. We aimed to reveal the short-term effects of low-level laser therapy (LLLT) on clinical and sonographic parameters in patients with symptomatic RCCT. METHOD: This prospective randomized controlled study analyzed 76 painful shoulders of 68 patients aged 18-75 years, with over 3 months of shoulder pain and where RCCT was confirmed sonographically. Patients in the LLLT group (received 5 LLLT sessions per week and home exercises for 5 days/week for 3 weeks) and the control group (received home exercises, 5 days/week for 3 weeks) were assessed clinically and sonographically just before and after treatment, recording pain intensity, range of motion (ROM), shoulder functional status, location (supraspinatus/infraspinatus, subscapularis), number and degree of calcification. Degree of calcification was determined with ultrasound and classified by the Bianchi-Martinoli classification. The LLLT was applied to the calcified areas marked under ultrasound guidance. RESULTS: Both groups showed statistically significant improvements in ROM, pain intensity, shoulder pain and disability index (SPADI) pain/disability/total, and degree of calcification after treatment. No significant change was achieved for calcification in the control group. Considering the change values, improvements in abduction, extension, pain intensity, SPADI pain/disability/total, calcification number, and calcification degree parameters were found to be statistically significantly better in the LLLT group than in the control group. CONCLUSION: Adding LLLT to the home program in treatment of symptomatic RCCT outperformed the home program alone, reducing the number and severity of calcifications, improving pain and disability.

Evaluation of bone health in terms of osteoporosis in adult patients with neuromuscular disease.

Background/aim: There are no current guidelines to help clinicians decide whether patients with adult neuromuscular disease (NMD) should be screened or treated for osteoporosis (OP). This study was undertaken to investigate the presence of OP in patients with various types of NMD and to examine the relationship between OP evaluation parameters and functional status, daily living activities, balance, and ambulation levels. Materials and methods: This cross-sectional study included 45 patients with NMDs. The patients were divided into 3 groups, depending on the affected component of the motor unit (neuronopathy group, neuropathy group, and myopathy group). The laboratory and demographic data were recorded from patient files. Functional level, pain, muscular strength, balance, and daily living activity scores were evaluated. The presence of OP was quantified using bone densitometry, fracture history, and biochemical parameters. Clinical findings were correlated with laboratory and dual-energy X-ray absorptiometry (DEXA) findings. Results: The mean hip T-score was -1.20, and the mean lumbar spine (L1-L4) T-score was -0.95 in all groups. Six patients with T-score values of -2.5 or below were detected. Vitamin D level was found to be low in all patient groups, especially in the myopathy group, but there was no significant difference (p > 0.05). There was a negative correlation between hip T-score and the frequency of falling (r = -0.604, p = 0.022), while a positive correlation was found between hip T-score and the age at which independent walking was no longer possible (r = 0.900, p = 0.037). Conclusion: OP is often overlooked in NMD patients with neurological problems and a high risk of falling. These patients should be screened for bone health and fragility.

Intramuscular botulinum toxin-A in complex regional pain syndrome resistant to standard treatment: a case report.

OBJECTIVE: To present a patient with complex regional pain syndrome type 1 (CRPS-I) and improvement of contracture of hand muscles and grip strength after successful treatment with botulinum neurotoxin­A (BoNT-A). CASE: A 53-year-old woman with CRPS­I experienced severe allodynia, swelling and autonomic changes in the left hand after a distal radius fracture. Over the succeeding months, she developed contracture of the left hand muscles which was treated with injection of BoNT­A into the hand muscles (10 points). RESULTS: In the patient treatment with BoNT­A an improvement was seen in the hand range of motion (ROM) and grip strength. CONCLUSION: Successful results can be obtained with BoNT­A injection in treatment-resistant CRPS­I cases which may develop joint contracture.

Comparison of Single Cell Transcriptome Sequencing Methods: Of Mice and Men.

Single cell RNAseq has been a big leap in many areas of biology. Rather than investigating gene expression on a whole organism level, this technology enables scientists to get a detailed look at rare single cells or within their cell population of interest. The field is growing, and many new methods appear each year. We compared methods utilized in our core facility: Smart-seq3, PlexWell, FLASH-seq, VASA-seq, SORT-seq, 10X, Evercode, and HIVE. We characterized the equipment requirements for each method. We evaluated the performances of these methods based on detected features, transcriptome diversity, mitochondrial RNA abundance and multiplets, among others and benchmarked them against bulk RNA sequencing. Here, we show that bulk transcriptome detects more unique transcripts than any single cell method. While most methods are comparable in many regards, FLASH-seq and VASA-seq yielded the best metrics, e.g., in number of features. If no equipment for automation is available or many cells are desired, then HIVE or 10X yield good results. In general, more recently developed methods perform better. This also leads to the conclusion that older methods should be phased out, and that the development of single cell RNAseq methods is still progressing considerably.

Factors influencing the willingness to participate in rehabilitation in patients with subacute stroke.

OBJECTIVE: The aim of this study was to examine the parameters that may influence the willingness of patients to participate in post-stroke rehabilitation. METHODS: Patients in the subacute phase of stroke who underwent inpatient rehabilitation for one month were included in this study. The primary outcome measure was the level of rehabilitation participation as measured on the Pittsburgh Rehabilitation Participation Scale (PRPS). Other outcome measures evaluated were Mini-Mental State Examination (MMSE) for cognitive functions, Brunnstrom stage for motor recovery, modified Rankin Scale (mRS) for disability, Functional Independence Measure for functionality, Pittsburgh Sleep Quality Index for sleep quality, and Beck Depression Inventory for emotional state. RESULTS: A total of 38 patients with first-time stroke were studied. A negative correlation was found between the participation in rehabilitation and body mass index (BMI) (r: -0.398p = 0.012), myocardial infarction (MI) history (r: -0.387p = 0.015) and mRS (r: -0.351p = 0.031), while a positive correlation was determined with MMSE (r: 0.432P = 0.007). A 1-unit increase in BMI, MI history, and mRS resulted in a 0.176, 0.673, and 0.294-unit decrease in participation in rehabilitation, respectively. In addition, a 1-unit increase in MMSE provided an increase of 0.606-unit in participation. CONCLUSION: BMI within normal limits, prevention/treatment of cardiovascular diseases, and well-being of physical and cognitive functions might be the factors that positively influence participation in rehabilitation process. We consider that it would be appropriate to evaluate these parameters with particular emphasis in stroke patients in the subacute period to be rehabilitated.

Effectiveness of kinesiotape and sham kinesiotape application in children with cerebral palsy with dysphagia: A randomized controlled study.

Objectives: This study aimed to investigate the short- and long-term effects of kinesiotaping (KT) on dysphagia in children with cerebral palsy (CP). Patients and methods: One hundred one CP patients (59 males, 42 females; mean age: 49.3±18.8 years; range, 2 to 6 years) with dysphagia referred between October 2017 and January 2020 were enrolled in the randomized controlled study. Children who met the study criteria were randomly assigned to the kinesiotape group (n=54) or the sham group (n=47). Specific swallowing evaluations were performed on all patients before the therapy. The KT or sham application protocole combined with conventional rehabilitaion therapy was conducted for six weeks. Evaluation parameters were repeated at 6 and 18 weeks. The evaluated parameters were compared within and between groups. Results: Drooling, weak tongue movement, chewing difficulty, coughing/choking and retching/vomiting during/after feeding, functional oral intake score, and meal time were found to be significantly improved at six weeks in the kinesiotape group compared to the sham group, and the clinical improvements were present at 18 weeks (p<0.05). There was no statistically significant difference in any parameter in the sham group at 6 and 18 weeks compared to the pretreatment (p>0.05). Conclusion: The addition of KT to a home exercise program is an effective method for dysphagia in CP.

Three-year follow-up outcomes of adult patients with Guillain-Barré Syndrome after rehabilitation.

Background: Guillain-Barré syndrome (GBS), the most common cause of acute paralytic neuropathy, covers a number of recognizably different variants. We aimed to evaluate the clinical characteristics of the patients with GBS and the outcome results of the patients after rehabilitation. Methods: We enrolled 24 adult patients with GBS and evaluated their demographic characteristics, signs, complications, functional levels, and residual symptoms at admission, discharge, and during the 1st and 3rd-year follow-up visits. Functional Independence Scale (FIM), Functional Ambulation Scale (FAS), Hughes functional grading scale, Six-Minute Walking Test (6MWT), and Fatigue Severity Scale (FSS) were used for patient evaluation. Results: In this study, patients with a mean age of 47.29 ± 16.2 years (40% female) were hospitalized for an average of 28.91 ± 25.6 days. The predominant symptoms experienced by these patients were fatigue (100%), neuropathic pain (70.8%), joint pain (54.2%), and autonomic dysfunction (50%). Significant changes were observed in FIM, Hughes functional grading scale, FAS, 6MWT, and MRC score at admission, discharge, and 1st/3rd-year follow-ups (p=0.000, p=0.000, p=0.000, p=0.001, p=0.000, respectively). Fatigue and Hughes score increased significantly with age (p=0.019, r=0.475; p=0.041, r=0.419, respectively). Negative correlations were found between age and FAS, 6MWT, and MRC score at 1st-year follow-up (p=0.025, r=-0.456; p=0.027, r=-0.450; p=0.008, r=-0.528). FSS was above 4 before admission and in 53.1% at 3rd-year follow-up, correlating negatively with 6MWT and MRC sum score. GBS clinical types showed no significant differences. Conclusion: Rehabilitation improves functional improvement in GBS patients, with long-term benefits observed. However, residual symptoms such as fatigue and neuropathic pain may persist despite functional improvement. These findings highlight the importance of incorporating rehabilitation into the management of GBS and addressing residual symptoms to improve patient outcomes.

USP7 regulates the ncPRC1 Polycomb axis to stimulate genomic H2AK119ub1 deposition uncoupled from H3K27me3.

Ubiquitin-specific protease 7 (USP7) has been implicated in cancer progression and neurodevelopment. However, its molecular targets remain poorly characterized. We combined quantitative proteomics, transcriptomics, and epigenomics to define the core USP7 network. Our multi-omics analysis reveals USP7 as a control hub that links genome regulation, tumor suppression, and histone H2A ubiquitylation (H2AK119ub1) by noncanonical Polycomb-repressive complexes (ncPRC1s). USP7 strongly stabilizes ncPRC1.6 and, to a lesser extent, ncPRC1.1. Moreover, USP7 represses expression of AUTS2, which suppresses H2A ubiquitylation by ncPRC1.3/5. Collectively, these USP7 activities promote the genomic deposition of H2AK119ub1 by ncPRC1, especially at transcriptionally repressed loci. Notably, USP7-dependent changes in H2AK119ub1 levels are uncoupled from H3K27me3. Even complete loss of the PRC1 catalytic core and H2AK119ub1 has only a limited effect on H3K27me3. Besides defining the USP7 regulome, our results reveal that H2AK119ub1 dosage is largely disconnected from H3K27me3.

The effect of robotic rehabilitation on posture and trunk control in non-ambulatory cerebral palsy.

The purpose of this study was to investigate the effects of a combined robot-assisted gait training (RAGT) with standard physiotherapy (PT) on trunk control and posture in non-ambulatory children with cerebral palsy (CP). This nonrandomized, controlled study included 31 CP assigned into two groups. Study Group: RAGT (three times a week, 30 min/session, for 6 weeks) + PT. Control group: PT only. The patients were evaluated using gross motor function measure (GMFM)-88 (Section B, Sitting) and Trunk Impairment Scale (TIS), pre-treatment and 3rd month post-treatment. In the RAGT group, significant improvements were observed in the GMFM-B and TIS scores at the 3rd month post-treatment (p < 0.05). Comparison of the changes in GMFM-B and TIS scores from end to beginning of the study, the change in TIS static are significantly higher in the RAGT group than control group (p < 0.05). Addition of RAGT to standard physiotherapy seems to improve trunk control, sitting balance, and posture in non-ambulatory CP.
