In this report we present a case of re-stabilization of the proximal radius using vascularized free fibular graft combined with anconeus arthroplasty to stabilize the transplanted fibula in a patient with large loss of the proximal radius due to Ewing's sarcoma. A 20-year-old woman had Ewing's sarcoma in the proximal three-fourths of the radius. The resection of large part of the radius containing radial head were necessary for removal of the sarcoma. Reconstruction of the proximal radius was performed using vascularized free fibular graft and the transplanted fibula was stabilized by attaching the anconeus to the proximal edge of the fibula. 2 years after surgery, she had neither recurrence nor metastasis, and achieved functional recovery. The combination anconeus arthroplasty with vascularized free fibular graft can be a good technique for re-stabilization of the elbow and recovery of the forearm function.

The anterolateral thigh (ALT) flap is a commonly used donor site for free tissue transfer, especially in head and neck reconstructions. The flap's success is primarily determined by the quality and quantity of its perforating vessels, which is why clinicians typically prefer harvesting from a healthy leg with intact vascular anatomy. Poliomyelitis typically causes unilateral lower limb paralysis, resulting in muscle atrophy and deformities.

Tamoxifen (TAM) is employed to treat premenopausal ER-positive breast cancer patients, but TAM resistance is the main reason affecting its efficacy. Thus, addressing TAM resistance is crucial for improving therapeutic outcomes. This study explored the potential role of Tinagl1, a secreted extracellular matrix protein, whose expression is compromised in TAM-resistant MCF-7 breast cancer cells (MCF-7R).

Background: The Hispanic/Latino population is not uniform. Prevalence and clinical outcomes of cardiac arrhythmias in ethnic background subgroups are variable, but the reasons for differences are unclear. Vectorcardiographic Global Electrical Heterogeneity (GEH) has been shown to be associated with adverse cardiovascular outcomes.

A vascularized free fibula flap is often used to reconstruct bone defects. However, bone resorption within the osteotomized segment is often observed. This may be attributed to damage to bone blood flow supplied by nonpenetrating periosteal vessels (NPPVs); however, there are few studies on NPPVs in the fibula.

Aims: Outcome in pulmonary arterial hypertension (PAH) is determined by right ventricular (RV) function adaptation to increased afterload. Echocardiography is easily available to assist bedside evaluation of the RV. However, no agreement exists about the feasibility and most relevant measurements.
