Predictive model of the efficiency of hematopoietic stem cell collection in patients with multiple myeloma and lymphoma based on multiple peripheral blood markers.

INTRODUCTION: Autologous hematopoietic stem cell transplantation (ASCT) has gained extensive application in the treatment of lymphoma and multiple myeloma (MM). Plenty of studies demonstrate that peripheral blood indicators could be considered potential predictive biomarkers for hematopoietic stem cells (HSCs) collection efficiency, including white blood cell count (WBC), monocyte count (Mono), platelet count (PLT), hematocrit, and hemoglobin levels. Currently, clinically practical predictive models based on these peripheral detection indicators to quickly, conveniently, and accurately predict collection efficiency are lacking. METHODS: In total, 139 patients with MM and lymphoma undergoing mobilization and collection of ASCT were retrospectively studied. The study endpoint was successful collection of autologous HSCs. We analyzed the effects of clinical characteristics and peripheral blood markers on collection success, and screened variables to establish a prediction model. We determined the optimal cutoff value of peripheral blood markers for predicting successful stem cell collection and the clinical value of a multi-marker prediction approach. We also established a prediction model for collection efficacy. RESULTS: Univariate and multivariate logistic regression analyses showed that the mobilization regimen, Mono, PLT, mononuclear cell count (MNC), and peripheral blood CD34+ cell count (PB CD34+ counts) were significant predictors of successful collection of peripheral blood stem cells (PBSC). Two predictive models were constructed based on the results of multivariate logistic analyses. Model 1 included the mobilization regimen, Mono, PLT, and MNC, whereas Model 2 included the mobilization regimen, Mono, PLT, MNC, and PB CD34+ counts. Receiver operating characteristic (ROC) curve analysis showed that the PB CD34+ counts, Model 1, and Model 2 could predict successful HSCs collection, with cutoff values of 26.92 × 106/L, 0.548, and 0.355, respectively. Model 1 could predict successful HSCs collection with a sensitivity of 84.62%, specificity of 75.73%, and area under the curve (AUC) of 0.863. Model 2 could predict successful HSCs collection with a sensitivity of 83.52%, specificity of 94.17%, and AUC of 0.946; thus, it was superior to the PB CD34+ counts alone. CONCLUSION: Our findings suggest that the combination of the mobilization regimen, Mono, PLT, MNC, and PB CD34+ counts before collection has predictive value for the efficacy of autologous HSCs collection in patients with MM and lymphoma. Using models based on these predictive markers may help to avoid over-collection and improve patient outcomes.

Spring buds of European woody plants have old 14C age.

Trees and shrubs maintain carbon reserves to support their functions during periods when metabolic demand exceeds carbon supply, such as during the dormant season. To gain a better understanding of carbon storage and utilisation dynamics of eight woody plant species in temperate Central Europe, bud scale and leaf samples were collected to determine the radiocarbon age of fresh sprouts in trees and shrubs, at three background sites avoiding local emissions that may influence affect the observed 14C/12C ratio. The accelerator mass spectrometry-based bomb-radiocarbon approach, to determine the age of the mobilized carbon in the plant bud samples from storage, was complemented by stable carbon isotope measurements. The bomb-radiocarbon dating technique was used to determine the age of the samples, while a northern hemispheric atmosphere 14CO2 dataset was used to calibrate the radiocarbon ages of the plant samples. The youngest observed calibrated radiocarbon age of the buds was over 4 years, and the oldest was even 9 years old. There was no significant difference between the ages of bud scales and embryonal leaf laminas. Our results show that there is a considerable amount of stored older carbon in the woody stems that can be used to produce buds in spring, which is a complex mixture of stored carbon of different ages, but there is no relationship between the radiocarbon age and the stable carbon isotope composition. The observed results show that not only the tree species, but shrubs also can store and use significantly older carbon pools, the carbon storage intensity is similar for trees with trunks and short-stemmed shrubs branching directly above the ground, i.e. carbon storage starts in young twigs and continues in ageing branches.

Treatment of wrist stiffness through posture orthosis and active exercise: A case report.

Introduction: Wrist fractures, particularly the distal radius, can result in significant stiffness and hand dysfunction if not mobilized early. The variable immobilization period post-fracture depends on fracture type, location, stability, and surgical intervention. Inadequate early mobilization typically leads to structured stiffness, influenced by patient health, injury mechanism, joint surface involvement, associated tissue injuries, and patient motivation. Case presentation: A 64-year-old female in good health suffered a distal radius fracture, treated with open reduction and internal fixation. A modified treatment plan, including custom orthosis and active wrist exercises, was initiated after the standard immobilization phase to enhance the range of motion while accommodating the patient's daily activities. Clinical discussion: The patient underwent 15 evaluations of active range of motion (AROM) using a goniometer, guided by the American Society of Hand Therapists. A Tissue Composition Analysis (TCA) was performed to guide the orthosis-treatment choice. Despite consistent improvement shown in AROM, it was inconclusive whether the modified treatment contributed significantly beyond the standard approach. Conclusions: While the patient's AROM improved, the treatment's effect on this single case cannot definitively confirm the efficacy of the modified approach. A more extensive study is necessary to evaluate the conservative treatment strategy's validity for such fractures in high-demand patients, considering the biomechanical complexity of the injury and the patient's professional needs.

[Comparison of etoposide combined with G-CSF and cyclophosphamide combined with G-CSF in the mobilization of autologous peripheral blood stem cells in patients with multiple myeloma].

Objective: The effect and safety of etoposide combined with G-CSF were compared with those of cyclophosphamide combined with G-CSF in autologous peripheral blood mobilization in patients with multiple myeloma (MM) . Methods: Patients with MM who received autologous peripheral blood stem cell mobilization and collection in the Department of Hematology, Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 1, 2020 to July 31, 2023 were included. A total of 134 patients were screened by propensity score matching technology according to a 1∶1 ratio. A total of 67 cases were each treated with ETO combined with G-CSF mobilization scheme (ETO group) and CTX combined with G-CSF mobilization scheme (CTX group). Their clinical data were retrospectively analyzed. Results: ①Collection results: the ETO and CTX groups [2 (1-3) d vs 2 (1-5) d; P<0.001] and CD34(+) cells [7.62×10(6) (2.26×10(6)-37.20×10(6)) /kg vs 2.73×10(6) (0.53×10(6)-9.85×10(6)) /kg; P<0.001] were collected. The success rate of collection was 100.0% (67/67) versus 76.1% (51/67) (P<0.001). Excellent rate of collection was 82.1% (55/67) versus 20.9% (14/67; P<0.001). Two patients in the ETO group switched protocols after 1 day of collection, and 11 patients in the CTX group switched protocols after 1-2 days of collection. ②Adverse reactions: granular deficiency with fever (21.5%[14/65] vs. 10.7%[6/56]; P=0.110), requiring platelet transfusion [10.7% (7/65) vs 1.8% (1/56) ; P=0.047]. ③Until the end of follow-up, 63 cases in the ETO group and 54 cases in the CTX group have undergone autologous transplantation. The median number of CD34(+) cells infused in the two groups was 4.62×10(6) (2.14×10(6)-19.89×10(6)) /kg versus 2.62×10(6) (1.12×10(6)-5.31×10(6)) /kg (P<0.001), neutrophil implantation time was 11 (9-14) d versus 11 (10-14) d (P=0.049), and platelet implantation time was 11 (0-19) d vs. 12 (0-34) d (P=0.035). One case in the CTX group experienced delayed platelet implantation. Conclusion: The mobilization scheme of etoposide combined with G-CSF requires relatively platelet transfusion, but the collection days are shortened. The collection success rate, excellent rate, and the number of CD34(+) cells obtained are high, and the neutrophil and platelet engraftment is accelerated after transplantation.

Realist process evaluation of the knowledge translation programme of a patient-oriented research network.

RATIONALE: The Knowledge Translation (KT) Programme of a pan-Canadian strategic patient-oriented research network focused on brain-based developmental disabilities aimed to mobilize knowledge relevant to the network members. The programme also promotes and studies integrated Knowledge Translation (iKT) approaches involving different interested parties, such as researchers, patient-partners and decision-makers, in all parts of the knowledge creation process. AIMS AND OBJECTIVES: The objective of this study is to advance research programme evaluation methods through a realist evaluation of the process of implementing iKT activities. METHODS: Realist process evaluation included: (1) development of initial programme theories (using the partnership synergy theory); (2) data collection and analysis; (3) synthesis and refinement of theories through engagement with literature; and (4) presentation of findings in context-mechanism-outcome (C-M-O) configurations. A range of project documentation records were reviewed for analysis, and three co-leads, a programme coordinator, and a senior research associate were consulted to contextualize the implementation process of relevant KT activities. RESULTS: Based on the developed C-M-O configurations, we identified five key mechanisms of generating synergy in the iKT processes: (1) Visible shared leadership that embodies what iKT looks like; (2) Researchers' readiness for iKT; (3) Adaptation and flexible allocation of resources to emerging needs; (4) Power sharing to create practical and creative knowledge; and (5) Collective voice for potential transformative impacts at the policy level. CONCLUSIONS: The current realist evaluation demonstrated how partnerships between researchers, patient-partners and other interested parties can synergistically generate new ways of thinking among all interested parties, actionable strategies to integrate users in research, and solutions to disseminate knowledge. In particular, we identified a pivotal role for patient-partners to act as equal decision-maker helps building and maintaining partnerships and consolidating KT strategies.

Strategies for knowledge mobilization by advanced practice nurses in three hospitals in Spain: a qualitative study.

BACKGROUND: Evidence-based practice, in conjunction with optimum care quality, improves patients' clinical outcomes. However, its implementation in daily clinical practice continues to present difficulties. The aim of this study was to identify the strategies applied by Advanced Practice Nurses (APNs) to foster adherence to clinical practice guideline recommendations. METHODS: An exploratory qualitative study was conducted with six focus groups at three public hospitals belonging to the Balearic Islands Health Care Service (Spain). The study participants were 32 ward nurses and 5 advanced practice nurses working routinely with inpatients at these hospitals. The study was conducted from November 2020 to January 2021, using thematic analysis, based on the COREQ checklist. RESULTS: Four major themes related to the facilitation process were identified either by RNs and APNs: the context of the project, APN contribution to nursing team management, healthcare provision on the ward, and the acquisition and application of knowledge. CONCLUSIONS: The APNs adapted their actions to the characteristics and needs of the local context, employing strategies aimed at improving teamwork, healthcare, and knowledge management. Each of these contributions enhanced the sustainability of the changes made.

Pain in Dementia: An Empirical Test of a Common Assumption.

Numerous, and often largely overlapping, observational pain assessment tools have been developed specifically to assess pain in older adults with dementia under the assumption that a specialized approach is necessary to evaluate pain in this population. However, this assumption has never been tested empirically. As an empirical test of this implicit assumption, our goal was to compare existing tools for people living with dementia (with respect to psychometric properties), not only against each other, but also against a tool developed for a different population with cognitive impairments. Videos of older adults with severe dementia recorded in long-term care settings were coded for pain behaviors in the laboratory. Trained coders coded pain behaviors in video segments of older adults with dementia during a quiet baseline condition as well as during a physical examination (designed to identify painful areas), using various observational pain assessment tools. An observational measure of agitation was employed to facilitate the assessment of discriminant validity. Consistent with our expectations, all pain tools (including the tool developed for younger people with cognitive impairments) successfully differentiated between painful and nonpainful states, with large effect sizes. This was the first study to compare tools specifically developed to assess pain in people living with dementia to a tool developed for a different population. Given that all tools under study showed satisfactory psychometric properties when tested on persons with dementia, this study suggests that the assumption that different tools are necessary for different populations with cognitive impairments cannot be taken for granted. PERSPECTIVE: This article challenges an implicitly held assumption that specialized tools are needed to assess pain in different populations with cognitive impairments. Given commonalities in pain expression across populations, further research is needed to determine whether population-specific tools are needed.

Routine Physical Therapy with and without Neural Mobilization in Chronic Musculoskeletal Neck Disorders with Nerve-Related Symptoms: Systematic Review and Meta-Analysis.

No previous study has evaluated the effectiveness of routine physical therapy with and without neural mobilization for patients with chronic musculoskeletal neck disorders and cervical radiculopathy. The objective is to evaluate the effectiveness of routine physical therapy with and without neural mobilization on pain and mobility in patients with chronic musculoskeletal neck disorders and cervical radiculopathy. A systematic review with meta-analysis of randomized clinical trials involving the use of neural mobilization techniques for the treatment of chronic musculoskeletal neck disorders and cervical radiculopathy was conducted. Methodological quality was assessed by the Cochrane Risk of Bias Tool and PEDro scale. Data were pooled and a meta-analysis was performed using a random effects model with Review Manager 5 software. Seven articles were included in our review. Significant differences were found in mobility but not in pain in favor of using routine physical therapy with neural mobilization for the treatment of chronic musculoskeletal neck disorders and cervical radiculopathy. Our results show that routine physical therapy accompanied by neural mobilization is superior for improving mobility in comparison with routine physical therapy alone in patients with musculoskeletal neck disorders and cervical radiculopathy.

Influence of anti-seasonal inundation on geochemical processes of arsenic speciation in the water-level-fluctuation zone soil of the Three Gorges Reservoir, China.

Since the completion of Three Gorges Dam, the water-level-fluctuation zone (WLFZ) of the Three Gorges Reservoir (TGR) experiences the periodic anti-seasonal inundation. However, knowledge for mechanisms of mobilization and transformation of arsenic (As) in WLFZ soils of the TGR remains scarce. To address this gap, a combination of field observation and simulated flooding experiments attempts to illustrate the As mobilization, the transformation between As(V) and As(III), and the factors driving these processes. The study revealed that anti-seasonal inundation (with a temperature at 13 â„ƒ) mitigated As release from submerged soils. Interestingly, the total As and ratio of As(III) (the more toxic form of As) concentrations in porewater at 13 â„ƒ was lower, and the prevalence of As(III) occurred later than those at 32 °C (imitate the seasonal inundation condition). The results indicated that the As reduction and the corresponding toxic risks in submerged soils were alleviated under anti-seasonal inundation. The study proposes the reduction of As-bearing manganese (Mn) mineral assemblages and competitive adsorption of dissolved organic carbon (DOC) as primary mechanisms for As mobilization. Furthermore, microorganism-mediated detoxification/reduction processes involving DOC, nitrogen, and Mn (oxyhydr)oxides were identified as central pathways for As(III) enrichment under anti-seasonal inundation. This study enhances understandings of the biogeochemical processes and fate of As in WLFZ soils influenced by artificial regulation of the reservoir.

Exploring the adaptability of TeachABI as an online professional development module for high school educators.

Objective: Educators often lack the knowledge and resources to assist students with acquired brain injury (ABI). TeachABI, an education module, was created to help elementary school teachers support students with ABI in classrooms. This study examined the adaptability of TeachABI for high school educators. Methods: A qualitative descriptive study explored high school educators' (n = 9) experiences reviewing TeachABI and its adaptability for high school through semi-structured interviews. The interview guide was informed by implementation and adaptation frameworks. Transcripts were examined using directed content analysis. Results: Teachers felt TeachABI was a good foundation for creating a high school-based education module. Adaptations were highlighted, such as streamlining content (e.g., mental health) and strategies (e.g., supporting test taking), to better meet educator needs. Conclusions: Using implementation science and adaptation frameworks provided a structured approach to explore the adaptive elements of TeachABI. The module was perceived as a suitable platform for teaching high school educators about ABI. Innovation: TeachABI is an innovative, user informed education module, providing a multi-modal (e.g., case study, videos) and replicable approach to learning about ABI. Applying frameworks from different fields provides concepts to consider when tailoring resources to align with educator needs (e.g., grade, class environment) and facilitate innovation uptake.

Shorter donor leukocyte telomere length is associated with poor peripheral blood stem cell mobilization induced by granulocyte colony-stimulating factor.

BACKGROUND/PURPOSE: Insufficient numbers of peripheral blood stem cells (PBSC) after granulocyte colony-stimulating factor (G-CSF) mobilization occurs in a significant proportion of PBSC collections, often from older age donors. Telomere length (TL) is often used as an indicator of an individual's biological age. This study aimed to investigate the relationship between donors' leukocyte TL and the outcome of G-CSF-induced PBSC mobilization in healthy unrelated donors. METHODS: Donors' leukocyte TLs and the outcome of G-CSF-induced PBSC mobilization, as assessed by pre-harvest CD34+ cell counts, were analyzed in 39 healthy PBSC donors. TL in a non-mobilized general population (n = 90) was included as a control group. G-CSF mobilization effect was categorized into three groups according to pre-harvest CD34+ cell count: poor (≤25/µL, PMD), intermediate (between 25 and 180/µL), and good (≥180/µl, GMD). RESULTS: Leukocyte TL of PBSC donors correlated well with pre-harvest CD34+ cell counts (r = 0.645, p < 0.001). Leukocyte TLs of PMDs (n = 8) were significantly shorter than those of GMDs (n = 9) and non-mobilization controls (p < 0.05). Moreover, all PMD TLs were below the 50th percentile, and 62.5% of PMDs had TLs below the 10th percentile of age-matched control participants. In contrast, no GMD TLs were below the 10th percentile; in fact, 33.3% (3/9) of them were above the 90th percentile. CONCLUSION: Our results indicate that shorter donor leukocyte TL is associated with poor G-CSF-induced PBSC mobilization. TL, which represents a donor's biological age, could be a potential predictor for mobilization outcome.

Barriers and opportunities faced by public health practitioners in using public health guidance on COVID-19: a knowledge translation exercise for the eCOVID-19 RecMap.

BACKGROUND AND OBJECTIVES: The COVID-19 pandemic prompted the scientific community to collaborate in an unprecedented way, with the rapid and urgent generation and translation of new knowledge about the disease and its causative agent. Iteratively, and at different levels of government and globally, population-level guidance was created and updated, resulting in the need for a living catalog of guidelines, the eCOVID-19 Recommendations Map and Gateway to Contextualization (RecMap). This article focuses on the approach that was used to analyze barriers and opportunities associated with using the RecMap in public health in Canada. STUDY DESIGN AND SETTING: A mixed qualitative and quantitative approach data were used to inform this knowledge mobilization project and inform feedback on implementation of the eCOVID-19 RecMap. This approach involved surveying 110 attendees from a public health webinar. Following this webinar, an evidence brief and series of case studies were created and disseminated to 24 Canadian public health practitioners who attended a virtual workshop. This workshop identified barriers and opportunities to improve RecMap use. RESULTS: This study helped to shed light on the needs that public health practitioners have when finding, using, and disseminating public health guidelines. Through the workshop that was conducted, opportunities for public health guidelines can be categorized into 4 categories: 1) information access, 2) awareness, 3) public health development, and 4) usability. Barriers that were identified can also be categorized into 4 categories: 1) usability, 2) information maintenance, 3) public health guidance, 4) awareness. CONCLUSION: This work will help to inform the development and organization of future public health guidelines, and the needs that public health practitioners have when engaging with them.

Predictive factors for peripheral blood stem cell mobilization in multiple myeloma in the era of novel therapies: A single-center experience.

OBJECTIVE: Multiple myeloma (MM) is the leading indication of autologous hematopoietic stem cell transplantation. The aim of this study was to determine the incidence of mobilization failure and characterize the risk factors associated with poor mobilization (PM) of MM patients in novel therapies era. METHODS: We conducted a retrospective study of 211 MM patients who received their first peripheral blood stem cells (PBSC) mobilization at our single center. The following data were collected: age, gender, clinical stage, disease status, complete blood cell count, induction regimen, CD34+ cell count in peripheral blood (PB), and PBSC collections. RESULTS: In addition to conventional drugs, 22 (10.4%) patients received daratumumab containing induction, and 33 (15.6%) patients used plerixafor for poor mobilization (pre-apheresis PB CD34+ cells <20/µL). Failure of collection occurred in 24 (11.4%) patients and was correlated with low white blood cell (WBC), ≥3 cycles of lenalidomide treatment before mobilization, steady-state mobilization and nouse of plerixafor are associated with mobilization failure. Daratumumab-based induction treatment ≥2 courses, albumin >41 g/L before mobilization, and steady-state mobilization were risk factors for PM in subgroups of patients treated with lenalidomide for <3 courses. In addition, Hepatitis B virus infection at baseline, thalassemia and measurable residual disease positivity were recognized as predictive factors for PM in subset of chemo-mobilization patients. CONCLUSION: In addition to some well-recognized risk factors, baseline WBC count and daratumumab exposure ≥2 courses before mobilization were revealed as the predictive factors of mobilization failure, providing consultation for preemptive use of plerixafor.

Comparison of biosimilar filgrastim and originator filgrastim for peripheral blood stem cell mobilization for allogeneic hematopoietic stem cell transplantation.

BACKGROUND: Nivestym, a biosimilar granulocyte colony-stimulating factor (G-CSF) to the originator filgrastim (Neupogen), is now being used for the mobilization of peripheral blood stem cells (PBSC) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). We aim to compare the efficacy of Nivestym and Neupogen for PBSC mobilization in healthy allogeneic donors. METHODS: We conducted a retrospective single-center study including 541 adult allo-HSCT donors receiving Nivestym (January 2013-July 2020), or Neupogen (July 2020-June 2023) for donor PBSC mobilization. Bivariate analysis was conducted using SPSS version 28. Statistical significance was determined at a p-value <.05. RESULTS: Our study included 541 allo-HSCT donors who received Neupogen (n = 345, 64%) or Nivestym (n = 196, 36%) for PBSC mobilization. The median age was 47 years (range 17-76). The median donor weight was 86 kg (95% confidence interval [CI]: 87-91). Donors receiving Neupogen had similar pre-G-CSF white blood cell count, CD34+ percentages, and circulating CD34+ count compared with donors receiving Nivestym. The Neupogen group had similar median PBSC product total neutrophil count, CD34+ percentage, absolute CD34+ count, and infused CD34+ dose compared with the Nivestym group. For donors aged 35 years or younger, the median CD34+ dose was higher in donors who received Neupogen compared with Nivestym (6.9 vs. 6.3 million cells/kg, p = .044). CONCLUSIONS: Nivestym demonstrated similar efficacy for PBSC mobilization compared with Neupogen among allo-HSCT donors. In donors aged 35 years or younger, a slightly lower PBSC product CD34+ count was noted with Nivestym compared with Neupogen.

[Clinical experience of JIAO Lin in treatment of knee osteoarthritis with manual mobilization of meridian muscle regions].

The paper introduces JIAO Lin's clinical experience in treatment of knee osteoarthritis (KOA) by manual mobilization of meridian muscle regions. Professor JIAO Lin believes that the key to the occurrence and development of KOA lies in the disorder of meridian muscle regions (sinews/fascia). In pathology, four stages are divided, i.e. the acute stage, the blockage stage, the contraction stage and the atrophy stage of muscle regions, characterized as multi-layer, multi-dimensional and multi-morphological distribution. In treatment, based on the principle, "taking pain sites as stimulating points", the sites, with reduced pain threshold and distributed along the meridian muscle regions, are regarded as "acupoints" for intervention. Manual mobilization of meridian muscle regions is the dominant approach, combined with routine acupuncture, heat-sensitive moxibustion, cupping and bloodletting corresponding to the features of syndromes and meridian manifestation at different stages. The comprehensive treatment may restore and reconstruct the physiological functions of the meridian muscle regions around knee joints by "nourishing tendons, strengthening bones and benefiting joints".

The effect of mulligan mobilization technique application in addition to conventional physiotherapy on pain and joint range of motion in people with neck pain.

BACKGROUND: To evaluate the effect of the Mulligan mobilization technique on pain intensity and range of motion in individuals with neck pain. METHODS: Forty individuals with mechanical neck pain were enrolled in the study. The patients were randomly divided into 2 groups and a total of 10 sessions of treatment were administered to all 2 groups for 2 weeks, 5 days a week. Mulligan mobilization technique, electrophysical agents, active range of motion, and stretching exercises were carried out in the Mulligan group. In contrast, only electrophysical agents and exercises were applied to the conventional physiotherapy group. Range of motion (ROM) of the neck, Visual Analog Scale (VAS), Neck Pain and Disability Scale (NPDS), and Short-Form 36 Health Survey (SF-36) were used for evaluation. RESULTS: Statistical analyses were done to compare the amounts at the baseline and immediately after treatment. Statistically significant improvements were found in the post-treatment ROM, VAS, NPDS values in both groups (p < 0.05). When the differences were compared, the results of the Mulligan group were significantly better than the conventional physiotherapy group (p < 0.05). There was no significant difference between the groups in terms of SF-36 parameters (p > 0.05). CONCLUSIONS: This study showed that the Mulligan mobilization technique plus conventional physiotherapy is more effective than conventional physiotherapy in increasing joint range of motion, reducing pain, and reducing neck disability. TRIAL REGISTRATON: ClinicalTrials.gov (NCT05074576).

Unknotting tech neck by breaking the cycle of pain and disability: Comparing the impact of instrument assisted soft tissue mobilization on specific muscles and superficial back arm line.

BACKGROUND: Computer professionals often develop a forward head posture due to prolonged hours of computer use, leading to neck pain. Instrument-assisted soft tissue mobilization (IASTM), an advanced technique for treating myofascial trigger points, has become increasingly popular for addressing these musculoskeletal issues. OBJECTIVES: The study aimed to compare the effectiveness of IASTM mobilization on SBAL (superficial back arm line) and SM(specific muscles-upper trapezius, levator scapulae, and sternocleidomastoid) in managing chronic neck pain among computer professionals. PARTICIPANTS & METHODS: The study involved 62 computer professionals, randomly divided into two groups. Group A received IASTM on SBAL and group B received IASTM on SM for neck pain each receiving three sessions weekly for four weeks. Outcome variables like Neck Disability Index (NDI), NPRS(Neck Pain Rating Scale), Craniovertebral angle (CVA), and range of motion (ROM) for flexion, and side flexion (right & left side) were evaluated at baseline, 2 weeks and 4 weeks. RESULTS: Significant improvement in NPRS were observed in both the SBAL and SM groups after 2 weeks of IASTM, wth the SBAL group demonstrating greater improvement. At 4 weeks, IASTM on SBAL showed significantly higher improvements in NPRS, CVA, NDI, and flexion compared to the SM group. The repeated measures ANOVA indicated a significant main effect of both time and group, along with a significant interaction between time and group for all outcome variables, except for CVA. CONCLUSION: The study indicates that IASTM on SBAL may offer a more effective treatment for chronic neck pain in computer professionals compared to targeting specific muscles.

Early Postoperative Weight-Bearing Ability after Total Hip Arthroplasty versus Bipolar Hemiarthroplasty in Elderly Patients with Femoral Neck Fracture.

Background: Femoral neck fractures are among the most common types of fractures and particularly affect elderly patients. Two of the most common treatment strategies are total hip arthroplasty (THA) and bipolar hemiarthroplasty (BA). However, the role of the different treatment strategies in the postoperative weight-bearing ability in the early postoperative phase is still not entirely clear. Methods: Patients who underwent either THA or BA were consecutively included in our prospective cohort study. Gait analysis was performed during the early postoperative period. The gait analysis consisted of a walking distance of 40 m coupled with the turning movement in between. During the gait analysis, the duration of the measurement, the maximum peak force and the average peak force were recorded. Results: A total of 39 patients were included, 25 of whom underwent BA and 14 of whom underwent THA. The maximum peak force during the gait analysis was, on average, 80.6% ± 19.5 of the body weight in the BA group and 78.9% ± 21.6 in the THA group. The additionally determined average peak force during the entire gait analysis was 66.8% ± 15.8 of the body weight in the BA group and 60.5% ± 15.6 in the THA group. Conclusions: Patients with femoral neck fractures undergoing THA and BA can achieve sufficient weight bearing on the operated leg in the early postoperative period. In our study, BA did not allow for a significantly higher average and maximum loading capacity compared with THA.
