[Impact of tumor size on actuarial survival of patients with primary breast sarcoma: a case-control study].

Objective. T: O determine whether tumor size, categorized as >5 cm or ≤5 cm, influences overall survival in patients with primary breast sarcoma.

Material And Methods: The study population consisted of patients diagnosed with primary breast sarcoma between January 1, 2010, and December 31, 2020.

Polarization-insensitive fiber-coupled superconducting-nanowire single photon detector using a high-index dielectric capping layer.

Superconducting-nanowire single photon detectors (SNSPDs) are able to reach near-unity detection efficiency in the infrared spectral range. However, due to the intrinsic asymmetry of nanowires, SNSPDs are usually very sensitive to the polarization of the incident radiation, their responsivity being maximum for light polarized parallel to the nanowire length (transverse-electric (TE) polarization). Here, we report on the reduction of the polarization sensitivity obtained by capping NbN-based SNSPDs with a high-index SiNx dielectric layer, which reduces the permittivity mismatch between the NbN wire and the surrounding area.

Role of Catheter's Position for Final Results in Intrathecal Drug Delivery. Analysis Based on CSF Dynamics and Specific Drugs Profiles.

Intrathecal drug delivery is an effective and safe option for the treatment of chronic pathology refractory to conventional pain therapies. Typical intrathecal administered drugs are opioids, baclofen, local anesthetics and adjuvant medications. Although knowledge about mechanisms of action of intrathecal drugs are every day more clear many doubt remain respect the correct location of intrathecal catheter in order to achieve the best therapeutic result.
