Notably, the proposed model is responsive to varied running patterns, producing data that are consistent with established human locomotion theory; demonstrating sound construct validity. Notwithstanding several assumptions, the model may be applied to quantify overground running demands on flat surfaces.Serotonin syndrome is a potentially life-threatening condition associated with increased serotonergic activity in the central nervous system. The increasing incidence of this condition is thought to parallel the increasing use of serotonergic agents in medical practice. The selective serotonin reuptake inhibitors are perhaps the most commonly implicated group of medications associated with serotonin syndrome. This case report describes the occurrence of postoperative serotonin syndrome in a patient on long-term sertraline who underwent coronary artery bypass graft and was treated with methylene blue for perioperative vasoplegia. It delineates the various clinical features commonly encountered and illustrates the recommended management modalities, including prevention, for this potentially lethal medical emergency. With prompt diagnosis and expeditious treatment, the patient has had full recovery.
To summarize the proposed mechanisms behind hypertension and QT interval prolongation associated with use of targeted systemic cancer therapies and provide recommendations for monitoring or managing these toxicities.
The cardiotoxic effects of targeted systemic cancer therapies represents a new paradigm of cancer treatment associated cardiovascular adverse events. National guidelines regarding optimal monitoring and management strategies for hypertension and QT interval prolongation associated with use of these therapies are lacking. While the pathophysiological drivers of hypertension due to targeted systemic cancer therapies differ by class of targeted therapy, general management strategies do not. Routine blood pressure monitoring throughout the duration of therapy is recommended for all agents. Patients who experience hypertension often can be treated with the addition or modification of antihypertensive therapies. Uncontrolled hypertension despite optimal medical management may require dose modifications or discontinuation of the targeted systemic cancer therapy. Electrocardiogram monitoring is recommended for patients who receive targeted therapies that may prolong the QT interval. Minimizing or managing drug interactions with other QT prolonging medications is recommended in addition to ensuring adequate electrolyte supplementation. Dose modifications or discontinuation of the targeted systemic therapy may be necessary for patients who experience QT interval prolongation.
Appropriate cardiovascular monitoring and timely management of treatment-emergent toxicities can optimize therapy for patients receiving targeted systemic cancer therapies associated with a risk of drug-induced hypertension or QT interval prolongation.

Atezolizumab is currently the only immunotherapy used in conjunction with nab-paclitaxel for locally advanced or triple negative breast cancer. Limited data is available regarding hemolytic anemia as a side effect of atezolizumab.
We describe a 59-year-old female with a history of triple negative breast cancer with bone metastases presenting for follow up on Cycle 1, Day 15 of atezolizumab and nab-paclitaxel (100 mg/m
). https://www.selleckchem.com/products/merbarone.html Patient's complete blood count (CBC) showed macrocytic anemia, with further workup significant for autoimmune hemolytic anemia (AIHA) attributed to atezolizumab.
Patient was started on a high dose prednisone taper starting at 80 mg daily for 16 days, folic acid 1 mg three times daily, iron sucrose, and darbepoetin alfa. Patient's counts recovered, and she was able to start Cycle 2 and continued through Cycle 10 without any additional pre-medications.
Hemolytic anemia induced by atezolizumab is a rare side effect that was successfully treated in this patient with a prednisone taper.

Appropriate dosing of therapeutic anticoagulation during periods of thrombocytopenia remains uncertain for patients undergoing hematopoietic stem cell transplants (HSCT). There is a paucity of literature on treatment outcomes for HSCT patients treated with non-prophylactic, but reduced doses of therapeutic anticoagulation during thrombocytopenia. The primary objective was to determine the incidence of major bleeding events during thrombocytopenia when reduced-dose enoxaparin was administered.
This is a retrospective review of patients with a venous thromboembolic event (VTE) who underwent HSCT and received reduced-dose enoxaparin during thrombocytopenia at the Massachusetts General Hospital (MGH) from April 1, 2016 to August 31, 2018. Incidence of recurrent VTE and bleeding events for up to one month were investigated. Rates of recurrent VTE and enoxaparin dose adjustments (0.5 mg/kg twice daily vs 1 mg/kg daily) were also reviewed.
Out of 172 patients reviewed, 27 patients met inclusion criteria. Thereon reduced-dose enoxaparin.
Exemestane, a steroidal aromatase inhibitor, is an important therapeutic option in the treatment of post-menopausal hormone receptor positive breast cancer. Adverse effects include hot flashes and bone loss, but rarely is hepatotoxicity reported. We report a case of exemestane induced cholestatic liver injury following exemestane initiation.
A now 77-year-old Caucasian female with primary biliary cirrhosis (PBC), and metastatic hormone receptor positive breast cancer originally diagnosed in 2000 who developed symptoms of pruritus, diarrhea, grade 2 transaminitis, and grade 1 hyperbilirubinemia three weeks after exemestane initiation.
Due to the patient's signs and symptoms, exemestane was discontinued and the patient was continued on cholestyramine until resolution of her laboratory abnormalities. Approximately a week after discontinuation, the patient was started and maintained on anastrozole without recurrence of her symptoms.
Hepatotoxicity with aromatase inhibitors have rarely been reported in clinical trials and to date, instances of exemestane induced hepatotoxicity has only been reported in two case reports.
