Large Solitary Lung Metastasis of a Matrix-Producing Metaplastic Breast Carcinoma: A Diagnostic Challenge.

Metaplastic breast carcinoma represents a diverse category of invasive breast cancers distinguished by the transformation of neoplastic epithelial cells into squamous cells or cells with mesenchymal appearance. Matrix-producing breast carcinoma is a variant of metaplastic breast carcinoma, an exceedingly uncommon malignancy accounting for less than 1% of all breast tumors. The precise origin of this tumor remains elusive; some molecular research points to a potential derivation from myoepithelial cells, while other studies emphasize the possibility of neoplastic transformation originating from multipotent stem cells.

Impact of a Medication Optimization Clinic on Heart Failure Hospitalizations.

Efforts to optimize guideline-directed medical therapy (GDMT) through team-based care may affect outcomes in patients with heart failure with reduced ejection fraction (HFrEF). This study evaluated the impact of an innovative medication optimization clinic (MOC) on GDMT and outcomes in patients with HFrEF. Patients with HFrEF who are not receiving optimal GDMT are referred to MOC and managed by a team comprised of a nurse practitioner or physician assistant, clinical pharmacist, and HF cardiologist.

Hemostasis testing and therapeutic plasma exchange: Results of a practice survey.

Introduction: Performing therapeutic plasma exchange (TPE) with albumin replacement decreases coagulation factor and platelet levels. No defined guidelines exist regarding laboratory testing to assess hemostasis in patients undergoing TPE.

Materials And Methods: A survey to evaluate hemostasis testing with TPE was distributed using online survey software.

Hemostasis management and therapeutic plasma exchange: Results of a practice survey.

Background: Patients undergoing therapeutic plasma exchange (TPE) may present with risks for hemorrhage or thrombosis. Use of replacement fluids devoid of coagulation factors will decrease factor levels and platelet levels. There are no established guidelines for hemostasis management in these situations.

Therapeutic hypothermia after cardiac arrest.

Irreversible brain damage and death are common outcomes after cardiac arrest, even when resuscitation is initially successful. Chances for both survival and a good neurologic outcome are improved when mild hypothermia is induced shortly after reperfusion. Unfortunately, this treatment is often omitted from advanced cardiac life support protocols.
