Operationalizing and digitizing person-centered daily functioning: a case for functionomics.

An ever-increasing amount of data on a person's daily functioning is being collected, which holds information to revolutionize person-centered healthcare. However, the full potential of data on daily functioning cannot yet be exploited as it is mostly stored in an unstructured and inaccessible manner. The integration of these data, and thereby expedited knowledge discovery, is possible by the introduction of functionomics as a complementary 'omics' initiative, embracing the advances in data science.

How to follow up patients with brachial plexus birth palsy in the long term: a survey of expert opinion.

There is no generally accepted diagnostic, treatment and follow-up algorithm for brachial plexus birth palsy in the current literature. This study evaluates the opinion of experts in the field of brachial plexus birth palsy surgery, to provide a follow-up guideline. A total of 35 experts attending an international meeting with a mean of 21.

The BMP7-Derived Peptide p[63-82] Reduces Cartilage Degeneration in the Rat ACLT-pMMx Model for Posttraumatic Osteoarthritis.

Objective: Osteoarthritis (OA) is characterized by articular cartilage erosion, pathological subchondral bone changes, and signs of synovial inflammation and pain. We previously identified p[63-82], a bone morphogenetic protein 7 (BMP7)-derived bioactive peptide that attenuates structural cartilage degeneration in the rat medial meniscal tear-model for posttraumatic OA. This study aimed to evaluate the cartilage erosion-attenuating activity of p[63-82] in a different preclinical model for OA (anterior cruciate ligament transection-partial medial meniscectomy [anterior cruciate ligament transection (ACLT)-pMMx]).

[Network medicine for people with movement complaints in the Netherlands: the Beweeghuis and other orthopaedic initiatives].

The prevalence of disorders related to the movement apparatus such as osteoarthritis and neck/back complaints is increasing, thereby compromising the accessibility and affordability of movement care. Besides, these complaints cause high burden of disease, high sick leave and decreased self-sustainability. These developments demand an integral multidisciplinary and line transcending approach.

Depletion of Abolishes ψ of 28S-U4966 and Affects the Ribosome Translational Apparatus.

Eukaryotic ribosomes are complex molecular nanomachines translating genetic information from mRNAs into proteins. There is natural heterogeneity in ribosome composition. The pseudouridylation (ψ) of ribosomal RNAs (rRNAs) is one of the key sources of ribosome heterogeneity.

Alignment of CCI total ankle replacements in relation to midterm functional outcome and complication incidence.

Background: Total ankle arthroplasty is increasingly used as a treatment for end stage ankle arthropathy. The aim of this study was to report the mid-term clinical function and survival results of Ceramic Coated Implant (CCI) ankle replacements and assess the association between the alignment of the CCI total ankle replacements and early functional outcome and complication incidence.

Methods: Data of 61 patients, who received 65 CCI implants between 2010 and 2016, were obtained from a prospectively documented database.

Long-term functional outcome of secondary shoulder surgery in brachial plexus birth palsy patients.

Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options.

Transhumeral amputation in brachial plexus lesion patients: A multicenter case series.

Background: A flail limb can be the result of a traumatic complete brachial plexus lesion. Some patients prefer retaining the flail limb, however some patients feel that a flail limb negatively affects daily life. In these circumstances an elective amputation is sometimes elected, however long-term follow-up, with respect to satisfaction and function is unknown.

The humeral suspension technique: a novel operation for deltoid paralysis.

Isolated deltoid paralysis is a rare pathology that can occur after axillary nerve injury due to shoulder trauma or infection. This condition leads to loss of deltoid function that can cause glenohumeral instability and inferior subluxation, resulting in rotator cuff muscle fatigue and pain. To establish dynamic glenohumeral stability, a novel technique was invented.

Clavicle lengthening, a novel operation technique to reduce pain in brachial plexus birth injury patients.

Background: Brachial plexus birth injury (BPBI) can lead to an imbalance of shoulder musculature that can lead to glenohumeral contractures, and joint and osseous deformities. Glenoid hypoplasia, lengthening of coracoid and acromion, protraction, lateral rotation and elevation of the scapula, and shortening of the clavicle can be observed. As a consequence, the trapezius, levator scapulae, rhomboid, and supraspinatus muscles are overloaded in daily activities causing pain, which can be difficult to treat conservatively.

Adaptation of the protein translational apparatus during ATDC5 chondrogenic differentiation.

Introduction: Ribosome biogenesis is integrated with many cellular processes including proliferation, differentiation and oncogenic events. Chondrogenic proliferation and differentiation require a high cellular translational capacity to facilitate cartilaginous extracellular matrix production. We here investigated the expression dynamics of factors involved in ribosome biogenesis during chondrogenic differentiation and determined whether protein translation capacity adapts to different phases of chondrogenic differentiation.

Preoperative community based functional high intensity interval training (-HIIT) with high-risk patients opting for lumbar spinal fusion: a pilot study.

Purpose: To determine the feasibility, safety and preliminary effectiveness of preoperative functional high-intensity interval training (-HIIT) for high-risk patients undergoing LSF.

Materials And Methods: High-risk patients eligible for elective 1-3 level LSF were included. Feasibility and safety of the preoperative f-HIIT program was determined by measuring participation and attrition rates, training adherence, adverse events, reached training intensity and preoperative progression in physical fitness.

Post-marketing surveillance on safety and efficacy of posterior spinal correction and fusion with the CD Horizon Solera instrumentation for adolescent idiopathic scoliosis. A retrospective cohort study.

Background: Post-Market Clinical Follow-Up has been integrated into the new Medical Device Regulations since 2020. The CD Horizon Solera 4.75 mm instrumentation (CD-Solera) was introduced worldwide in 2009, and specifically intended for surgical treatment of pediatric and adolescent scoliosis patients.

BMP7 increases protein synthesis in SW1353 cells and determines rRNA levels in a NKX3-2-dependent manner.

BMP7 is a morphogen capable of counteracting the OA chondrocyte hypertrophic phenotype via NKX3-2. NKX3-2 represses expression of RUNX2, an important transcription factor for chondrocyte hypertrophy. Since RUNX2 has previously been described as an inhibitor for 47S pre-rRNA transcription, we hypothesized that BMP7 positively influences 47S pre-rRNA transcription through NKX3-2, resulting in increased protein translational capacity.

Uncovering pathways regulating chondrogenic differentiation of CHH fibroblasts.

Mutations in the non-coding snoRNA component of mitochondrial RNA processing endoribonuclease (RMRP) are the cause of cartilage-hair hypoplasia (CHH). CHH is a rare form of metaphyseal chondrodysplasia characterized by disproportionate short stature and abnormal growth plate development. The process of chondrogenic differentiation within growth plates of long bones is vital for longitudinal bone growth.

Local bone metabolism during the consolidation process of spinal interbody fusion.

Introduction: Although computed tomography (CT) can identify the presence of eventual bony bridges following lumbar interbody fusion (LIF) surgery, it does not provide information on the ongoing formation process of new bony structures. F sodium fluoride (F-NaF) positron emission tomography (PET) could be used as complementary modality to add information on the bone metabolism at the fusion site. However, it remains unknown how bone metabolism in the operated segment changes early after surgery in uncompromised situations.

A Systematic Review of Focal Cartilage Defect Treatments in Middle-Aged Versus Younger Patients.

Background: Focal cartilage defects are often debilitating, possess limited potential for regeneration, are associated with increased risk of osteoarthritis, and are predictive for total knee arthroplasty. Cartilage repair studies typically focus on the outcome in younger patients, but a high proportion of treated patients are 40 to 60 years of age (ie, middle-aged). The reality of current clinical practice is that the ideal patient for cartilage repair is not the typical patient.

BMP7 reduces the fibrocartilage chondrocyte phenotype.

The fibrocartilage chondrocyte phenotype has been recognized to attribute to osteoarthritis (OA) development. These chondrocytes express genes related to unfavorable OA outcomes, emphasizing its importance in OA pathology. BMP7 is being explored as a potential disease-modifying molecule and attenuates the chondrocyte hypertrophic phenotype.

Sox9 Determines Translational Capacity During Early Chondrogenic Differentiation of ATDC5 Cells by Regulating Expression of Ribosome Biogenesis Factors and Ribosomal Proteins.

Introduction: In addition to the well-known cartilage extracellular matrix-related expression of Sox9, we demonstrated that chondrogenic differentiation of progenitor cells is driven by a sharply defined bi-phasic expression of Sox9: an immediate early and a late (extracellular matrix associated) phase expression. In this study, we aimed to determine what biological processes are driven by Sox9 during this early phase of chondrogenic differentiation.

Materials: Sox9 expression in ATDC5 cells was knocked down by siRNA transfection at the day before chondrogenic differentiation or at day 6 of differentiation.

Interchangeability of Diverse Analog Scales Used Within the Constant-Murley Score.

Purpose: To assess the interchangeability of various existing answering scales within the subjective part of the Constant-Murley Score (CMS) and to determine the effect of the different answering scales on the inter- and intraobserver reliability.

Methods: In this prospective, single-center, cross-sectional trial, patients with shoulder problems were included from June to September 2018. Subjects recruited were 18 years or older, presented various shoulder complaints, e.

Discovery of bone morphogenetic protein 7-derived peptide sequences that attenuate the human osteoarthritic chondrocyte phenotype.

Treatment of osteoarthritis (OA) is mainly symptomatic by alleviating pain to postpone total joint replacement. Bone morphogenetic protein 7 (BMP7) is a candidate morphogen for experimental OA treatment that favorably alters the chondrocyte and cartilage phenotype. Intra-articular delivery and sustained release of a recombinant growth factor for treating OA are challenging, whereas the use of peptide technology potentially circumvents many of these challenges.

Biomechanical comparison of semirigid junctional fixation techniques to prevent proximal junctional failure after thoracolumbar adult spinal deformity correction.

Background Context: Adult spinal deformity patients treated operatively by long-segment instrumented spinal fusion are prone to develop proximal junctional kyphosis (PJK) and failure (PJF). A gradual transition in range of motion (ROM) at the proximal end of spinal instrumentation may reduce the incidence of PJK and PJF, however, previously evaluated techniques have not directly been compared.

Purpose: To determine the biomechanical characteristics of five different posterior spinal instrumentation techniques to achieve semirigid junctional fixation, or "topping-off," between the rigid pedicle screw fixation (PSF) and the proximal uninstrumented spine.

Ultra-high-molecular-weight polyethylene sublaminar tape as semirigid fixation or pedicle screw augmentation to prevent failure in long-segment spine surgery: an ex vivo biomechanical study.

Objective: Complications after adult spinal deformity surgery are common, with implant-related complications occurring in up to 27.8% of cases. Sublaminar wire fixation strength is less affected by decreasing trabecular bone density in comparison to pedicle screw (PS) fixation due to the predominant cortical bone composition of the lamina.

Aggrecan and COMP Improve Periosteal Chondrogenesis by Delaying Chondrocyte Hypertrophic Maturation.

The generation of cartilage from progenitor cells for the purpose of cartilage repair is often hampered by hypertrophic differentiation of the engineered cartilaginous tissue caused by endochondral ossification. Since a healthy cartilage matrix contains high amounts of Aggrecan and COMP, we hypothesized that their supplementation in the biogel used in the generation of subperiosteal cartilage mimics the composition of the cartilage extracellular matrix environment, with beneficial properties for the engineered cartilage. Supplementation of COMP or Aggrecan was studied during chondrogenic differentiation of rabbit periosteum cells and periosteum-derived chondrocytes.
