Supporting physical activity for health: What activities would people with transtibial amputation like to perform?

Background: Participation in physical activity (PA) for health by people with transtibial amputation (PTTA) may moderate comorbidities experienced by this population. It is more likely that interventions which aim to increase participation by PTTA in PA for health will increase participation if the type of PA used is tailored to the preferences of the PTTA.

Objective: This study aimed to identify the types of PA performed by PTTA, the types of PA PTTA who performed no physical activities would like to adopt, and if these outcomes were influenced by the cause of amputation.

Undifferentiated Round Cell Sarcoma With CRTC1::SS18 Fusion: Expanding Clinicopathologic Features of a Rare Translocation Sarcoma With Prominent Desmoplastic Stroma.

Undifferentiated round cell sarcomas (URCS) represent a diverse group of tumors, including conventional Ewing sarcoma, round cell sarcoma with EWSR1/FUS-non-ETS fusions, CIC-rearranged sarcoma, and sarcoma with BCOR alterations. Since 2018, 3 cases of URCS with a novel CRTC1::SS18 gene fusion have been reported in the literature. Herein, we report 3 additional cases of CRTC1::SS18 sarcoma, thereby doubling the number of described cases and expanding the clinicopathologic features of this rare translocation sarcoma.

Are inter-limb differences in change of direction velocity and angle associated with inter-limb differences in kinematics and kinetics following anterior cruciate ligament reconstruction?

Background: Quantifying inter-limb differences in kinematics and kinetics during change of direction is proposed as a means of monitoring rehabilitation following anterior cruciate ligament reconstruction (ACLR). Velocity and centre of mass (CoM) deflection angle are fundamental task descriptors that influence kinematics and kinetics during change of direction. Inter-limb differences in approach velocity and CoM deflection angle have been identified following ACLR and may contribute to the presence of inter-limb differences in kinematics and kinetics during change of direction.

Training program intervention to encourage physical activity for health in people with transtibial amputation: A feasibility study.

Background: People with transtibial amputation (PTTA) would benefit from increased physical activity levels (PAL) but generic programs developed to support increased PAL do not address the barriers which PTTA experience.

Objective: To evaluate the effect of a 12-week training program, developed for PTTA, on their PAL.

Methods: Ten PTTA participated in a 12-week training program, which involved one instructor-led supervised group session per week.

Metastatic sarcomatoid carcinoma to bone.

Background And Objectives: Distinguishing sarcomatoid carcinoma from primary sarcoma is clinically important. We sought to characterize metastatic sarcomatoid bone disease and its management.

Methods: We analyzed the characteristics of all cases of sarcomatoid carcinoma to bone at a single institution from 2001 to 2021, excluding patients with nonosseous metastases.
