Efficient bone marrow irradiation and low uptake by non-haematological organs with an yttrium-90-anti-CD66 antibody prior to haematopoietic stem cell transplantation.

We report the results of a Phase I radiation dose escalation study using an yttrium-90 (Y) labelled anti-CD66 monoclonal antibody given with standard conditioning regimen for patients receiving haematopoietic stem cell transplants for myeloid leukaemia or myeloma. The Y-labelled anti-CD66 was infused prior to standard conditioning. In total, 30 patients entered the trial and 29 received Y-labelled mAb, at infused radiation activity levels of 5, 10, 25, or 37.

Racial and gender disparities in utilization of outpatient total shoulder arthroplasties.

Background: Utilization in outpatient total shoulder arthroplasties (TSAs) has increased significantly in recent years. It remains largely unknown whether utilization of outpatient TSA differs across gender and racial groups. This study aimed to quantify racial and gender disparities both nationally and by geographic regions.

Predictive value of sarcopenia components for all-cause mortality: findings from population-based cohorts.

Background: Low grip strength and gait speed are associated with mortality. However, investigation of the additional mortality risk explained by these measures, over and above other factors, is limited.

Aim: We examined whether grip strength and gait speed improve discriminative capacity for mortality over and above more readily obtainable clinical risk factors.

A preoperative risk assessment tool for predicting adverse outcomes among total shoulder arthroplasty patients.

Background: With the increased utilization of Total Shoulder Arthroplasty (TSA) in the outpatient setting, understanding the risk factors associated with complications and hospital readmissions becomes a more significant consideration. Prior developed assessment metrics in the literature either consisted of hard-to-implement tools or relied on postoperative data to guide decision-making. This study aimed to develop a preoperative risk assessment tool to help predict the risk of hospital readmission and other postoperative adverse outcomes.

Global pattern, trend, and cross-country inequality of early musculoskeletal disorders from 1990 to 2019, with projection from 2020 to 2050.

Background: This study aims to estimate the burden, trends, forecasts, and disparities of early musculoskeletal (MSK) disorders among individuals ages 15 to 39 years.

Methods: The global prevalence, years lived with disabilities (YLDs), disability-adjusted life years (DALYs), projection, and inequality were estimated for early MSK diseases, including rheumatoid arthritis (RA), osteoarthritis (OA), low back pain (LBP), neck pain (NP), gout, and other MSK diseases (OMSKDs).

Findings: More adolescents and young adults were expected to develop MSK disorders by 2050.

Hip Fracture Treatment and Outcomes Among Community-Dwelling People Living With Dementia.

Importance: The decision for surgical vs nonsurgical treatment for hip fracture can be complicated among community-dwelling people living with dementia.

Objective: To compare outcomes of community-dwelling people living with dementia treated surgically and nonsurgically for hip fracture.

Design, Setting, And Participants: This retrospective cross-sectional study undertook a population-based analysis of national Medicare fee-for-service data.

Risk Factor Analysis for Growth Arrest in Paediatric Physeal Fractures-A Prospective Study.

Fractures through the physis account for 18-30% of all paediatric fractures, leading to growth arrest in up to 5.5% of cases. We have limited knowledge to predict which physeal fractures result in growth arrest and subsequent deformity or limb length discrepancy.

The effect of calcaneus and metatarsal head offloading insoles on healthy subjects' gait kinematics, kinetics, asymmetry, and the implications for plantar pressure management: A pilot study.

Background: The global number of people with diabetes is estimated to reach 643 million by 2030 of whom 19-34% will present with diabetic foot ulceration. Insoles which offload high-risk ulcerative regions on the foot, by removing insole material, are the main contemporary conservative treatment to maintain mobility and reduce the likelihood of ulceration. However, their effect on the rest of the foot and relationship with key gait propulsive and balance kinematics and kinetics has not been well researched.

Evaluation of Pore Size Graded Bone Scaffolds with Different Material Composition.

The demand for biomimetic and biocompatible scaffolds in equivalence of structure and material composition for the regeneration of bone tissue is relevantly high. This article is investigating a novel three-dimensional (3D) printed porous structure called bone bricks with a gradient pore size mimicking the structure of the bone tissue. Poly-ɛ-caprolactone (PCL) combined with ceramics such as hydroxyapatite (HA), β-tricalcium phosphate (TCP), and bioglass 45S5 were successfully mixed using a melt blending method and fabricated with the use of screw-assisted extrusion-based additive manufacturing system.

Five-Year Mortality Rates Following Elective Shoulder Arthroplasty and Shoulder Arthroplasty for Fracture in Patients Over Age 65.

Background: To effectively counsel patients prior to shoulder arthroplasty, surgeons should understand the overall life trajectory and life expectancy of patients in the context of the patient's shoulder pathology and medical comorbidities. Such an understanding can influence both operative and nonoperative decision-making and implant choices. This study evaluated 5-year mortality following shoulder arthroplasty in patients ≥65 years old and identified associated risk factors.

Comparing Rates of Radiographic Baseplate Loosening Between Cement and Cementless INFINITY Total Ankle Prostheses.

Introduction: Total ankle replacement is indicated for end-stage ankle osteoarthritis. Periprosthetic radiolucency, from separation between the bone and implant, is suggested to be indicative of potential prosthesis failure risk. Anchoring implants with cement may mitigate this.

Lifecourse correlates of self-rated health and associations with subsequent mortality: findings from the Hertfordshire Cohort Study.

Background: Poor self-rated health (SRH) has been shown to predict adverse health outcomes among older people, however these associations have traditionally only been considered at one point in the lifecourse, usually midlife or later. Here we examined lifecourse correlates of SRH in early, mid and later life, relating these to subsequent risk of mortality in a community-dwelling cohort.

Methods: 2989 men and women from the Hertfordshire Cohort Study (HCS) were included in this study.

An Effective Program to Reduce Malpractice Claims and Payments in a Large Orthopaedic Practice.

Background: High reliability in health care requires a balance between intentionally designed systems and individual professional accountability. One element of accountability includes a process for addressing clinicians whose practices are associated with a disproportionate share of patient complaints. This study aimed to evaluate the impact of the Patient Advocacy Reporting System (PARS), a tiered intervention model to reduce patient complaints about clinicians.

Trabecular bone variation in the gorilla calcaneus.

Objectives: Calcaneal external shape differs among nonhuman primates relative to locomotion. Such relationships between whole-bone calcaneal trabecular structure and locomotion, however, have yet to be studied. Here we analyze calcaneal trabecular architecture in Gorilla gorilla gorilla, Gorilla beringei beringei, and G.

"Preventing nail migration by stack nailing in forearm fractures" - A technical note.

Diaphyseal forearm fractures are typically treated with open reduction and plate fixation, which has been proven to be the most effective method in numerous trials. However, the risk of periosteal stripping, haemorrhage evacuation, nonunion, and infection is always present and may cause a delayed union and other surgical consequences. Although intramedullary nails have been mentioned in the literature for forearm bone fractures, issues regarding their common complication of nail migration, especially of the ulnar fracture, before the fracture has been consolidated is an issue, and has not been addressed.

Comparing Single-Tooth Implant Placement With and Without Allogeneic Soft Tissue Augmentation: A Randomized Clinical Trial.

Purpose: To explore the effect of adding an allogeneic soft tissue graft at the time of single implant placement using a fully digital workflow for implant placement and restoration without making either analog or digital impressions.

Materials And Methods: A prospective randomized clinical study was performed enrolling 39 participants requiring single-tooth implants. The patients were randomized into one of two groups: (1) the graft group, which received an allogeneic dermal graft at the time of implant placement (n = 19), or (2) the nongraft group (n = 20).
