Following local treatment and doxorubicin-containing standard chemotherapy, 42 patients with surgical Stage II or IIIA breast cancer containing ten or more involved axillary nodes and 13 patients with Stage IIIB disease were treated with high-dose chemotherapy (TMJ) consisting of thiotepa (750 mg/m2), mitoxantrone (40 mg/m2), and carboplatin (1000 mg/m2), with autologous bone marrow (ABM) and peripheral stem cell (PSC) transplant, followed by irradiation and/or hormone therapy. Sargramostim (GM-CSF) support was given to most patients. The median time to transfusion independence was two weeks. Severe non-hematologic toxicity was uncommon, with no intensive care admission or treatment-related death. At a median follow-up of 17 months, eight patients have relapsed and five have died of tumor progression. No statement can yet be made regarding adjuvant efficacy, but this high-dose regimen is very well tolerated.

January 2025
Division of Adolescent and Young Adult Medicine, Children's Hospital Los Angeles, Keck School of Medicine of University of Southern California, 3250 Wilshire Blvd, Suite 300, Los Angeles, CA 90010.
Study Objective: Compare the length of hospital stay of adolescents admitted for severe anemia (hemoglobin ≤ 8 g/dL) due to acute abnormal uterine bleeding (AUB) treated with high-dose combined oral contraceptive pills (HD-OCPs) versus those treated with HD-OCPs and intravenous conjugated equine estrogen, also referred to as dual therapy.
Design, Setting, And Participants: This is a single institution retrospective cohort study of adolescents hospitalized for the management of acute AUB and severe anemia between July 1, 2004, to January 1, 2020. Subjects were excluded if they were pregnant, had a malignancy, thrombocytopenia, treated with other hormonal therapies, or if bleeding stopped prior to admission.
Different Regimens of Preoperative Carbohydrate Loading on Insulin Resistance: A Network Meta-analysis.

School of Graduate, Tianjin University of Traditional Chinese Medicine, No.10 Poyang Lake Road, Tuanbo New City West, Jinghai District, Tianjin, China.
Background & Aims: The effectiveness of preoperative carbohydrate loading(PCL) on postoperative insulin resistance(IR) is controversial. In addition, the effect of different doses of carbohydrates on postoperative IR is also controversial. Therefore, this study aimed to investigate the efficiency of PCL on postoperative IR and the optimal regimen for the effect on postoperative IR.

Department of Medicine, MedStar Health, Baltimore, Maryland, United States.
Objectives: Antifibrinolytics, such as tranexamic acid (TXA), are widely used in cardiac surgery to reduce bleeding risks; however, the optimal dosage for TXA infusion remains a subject of debate. Hence, this study aims to evaluate the safety and efficacy of high-dose compared with low-dose TXA infusion in cardiac surgery patients.
Methods: PubMed, SCOPUS, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched until June 10, 2023, for studies assessing efficacy outcomes (e.
Hematopoietic stem cell transplantation as rescue therapy for refractory autoimmune retinopathy: a case report.
Front Immunol
January 2025
Department of Ophthalmology, National University Hospital, National University Health System, Singapore, Singapore.
Autoimmune retinopathy (AIR) is a rare, potentially blinding retinal disease that remains a challenging condition to manage when resistant to conventional immune-modulatory approaches. We report clinical and electrophysiological improvement in a 49-year-old patient who underwent an autologous hematopoietic stem cell transplant (aHSCT) for thymoma-associated AIR after experiencing progressive disease despite receiving periocular and systemic steroids, mycophenolate mofetil, baricitinib, tacrolimus, bortezomib, rituximab, plasmapheresis, and intravenous immunoglobulin. The aHSCT had two stages: (i) peripheral blood stem cell harvest following mobilization with cyclophosphamide and granulocyte colony-stimulating factor, and (ii) conditioning regimen with plasmapheresis, rituximab, cyclophosphamide, and anti-thymocyte globulin high-dose therapy, followed by autologous hematopoietic cell infusion of 5.

Cushing syndrome due to ectopic adrenocorticotropic hormone (ACTH) secretion (EAS) is rare and may progress rapidly, making treatment very challenging. We report a 27-year-old woman with metastatic neuroendocrine tumor (NET) who presented with sudden onset and rapidly progressing fatigue, muscle weakness, and weight gain. Laboratory findings confirmed severe EAS with new onset hypocalcemia, hypokalemia, and hyperglycemia.
