A case of desmoplastic myxoid tumor, SMARCB1 mutant, in the pineal region.

Desmoplastic myxoid tumor (DMT), SMARCB1 mutant is a recently proposed new entity that mainly occurs in the pineal region and has epigenetic features similar to those of atypical teratoid/rhabdoid tumors (AT/RT)-MYC and poorly differentiated chordomas. Herein, we present a new case of a 33-year-old man with headaches, dizziness, nausea, vomiting, and blurred vision, who was initially found to have a suspicious germinoma on imaging. After surgical removal of the lesion, the postoperative pathological diagnosis was DMT, SMARCB1 mutant.

Vortex soliton molecule in a fiber laser.

We report the generation of vortex soliton molecules (VSMs) in a passively mode-locked fiber laser based on a mode selective coupler (MSC). ±1-order VSMs with variable numbers of molecules are observed. By adjusting the polarization state of the light in the cavity, we further demonstrate the process in which one VSM splits to multiple.

Patient Engagement in ACO Practices and Patient-reported Outcomes Among Adults With Co-occurring Chronic Disease and Mental Health Conditions.

Background: Accountable care organizations (ACOs) have increased their use of patient activation and engagement strategies, but it is unknown whether they achieve better outcomes for patients with comorbid chronic physical and mental health conditions.

Objectives: To assess the extent to which practices with patient-centered cultures, greater shared decision-making strategies, and better coordination among team members have better patient-reported outcomes (PROs) for patients with diabetes and/or cardiovascular and comorbid mental health diagnoses.

Research Design: Sixteen practices randomly selected from top and bottom quartiles of a 39-item patient activation/engagement implementation survey of primary care team members (n=411) to assess patient-centered culture, shared decision-making, and relational coordination among team members.

Recurrent retroperitoneal extra-GIST with rhabdomyosarcomatous and chondrosarcomatous differentiations: a rare case and literature review.

Selective tyrosine kinase inhibitor (TKI) targeting KIT and PDGFRA is the frontline therapy for metastatic and unresectable GIST patients. Some initially responsive patients experience tumor progress because of secondary drug resistance, and some cases can develop heterogeneous differentiation. Here we report a rare case of recurrent retroperitoneal extra-GIST with rhabdomyosarcomatous and chondrosarcomatous differentiation with TKI therapy after surgical tumorectomy.

Input-to-state stability of switched nonlinear systems with time delays under asynchronous switching.

This paper is concerned with analyzing input-to-state stability (ISS) for a class of switched nonlinear systems with time delays under asynchronous switching. Due to the existence of switching delay, the switching of the controller does not coincide accurately with the switching of the system.When the subsystem is stabilized with the matched controller, the subsystem is ISS; otherwise, the subsystem may be not ISS.
