AI Article Synopsis

  • Complementary and alternative medicine (CAM) includes a variety of treatments and products not commonly recognized by conventional healthcare professionals, and can potentially interfere with chemotherapy in cancer patients.
  • Many cancer patients use CAM for various reasons, including managing chemotherapy side effects or treating unrelated conditions, and their choices can be influenced by input from friends, family, and healthcare practitioners.
  • While rigorous clinical trials show no CAM treatments for cancer provide benefit beyond a placebo effect, certain mind-body therapies and ginger for nausea are supported as safe options during chemotherapy.

Article Abstract

Complementary and alternative medicine (CAM) cover a broad and diverse group of treatments and products that do not tend to be widely used by conventional healthcare professions. CAM that is systemically absorbed is the most likely to interfere with concurrent chemotherapy and potentially cause harm to cancer patients. Patients receiving chemotherapy may be consuming CAM to treat cancer, to lessen chemotherapy side effects, for symptom management, or to treat conditions unrelated to their cancer. A small proportion of cancer patients decide to use CAM alone to treat cancer and delay conventional treatment. Cancer patients may be influenced in their CAM decision-making by others: practitioners, family, friends, spouse and even casual acquaintances met in waiting rooms and support groups. This influence may range from encouraging and supporting the patient's decision through to making the decisions for the patient. When tested in rigorous clinical trials, no CAM cancer treatments alone have shown benefit beyond placebo. With the exception of ginger to treat chemotherapy-induced nausea, there is no compelling evidence overriding risk to take complementary medicines for supportive care during chemotherapy treatment. There is, however, established evidence to use mind-body complementary therapies for supportive care during chemotherapy treatment.

Background: Solid organ transplantation (SOT) is vital for end-stage organ failure but faces challenges like organ shortage and rejection. Artificial intelligence (AI) offers potential to improve outcomes through better matching, success prediction, and automation. However, the evolution of AI in SOT research remains underexplored.

Background: Spinal ependymomas are typically slow-growing tumors with a favorable prognosis. Recently, a new aggressive subtype has emerged with its own distinct histopathological and molecular features characterized by MYCN amplification. However, this subtype of spinal ependymoma is rare, and studies on its imaging characteristics are limited.

We report a case of pulseless electrical activity (PEA) associated with profound hypermagnesemia immediately after cementation of a novel magnesium-based cement in spine surgery. During T8 to T12 posterior instrumentation and decompression laminectomy for vertebral metastasis secondary to lung cancer, a 61-year-old Chinese woman developed sudden hypotension and went into PEA immediately after injection of a novel magnesium-based cement. Intraoperative fluoroscopic imaging did not show any notable cement extravasation.

Objectives: Detection of fat content in thymic lesions is essential to differentiate thymic hyperplasia from thymic tumors. This study assesses the reliability and efficacy of "iterative decomposition of water and fat with echo asymmetry and least-squares estimation quantization" IDEAL-IQ magnetic resonance sequence in distinguishing thymic hyperplasia from low-risk thymoma and thymic lymphoma in adulthood.

Methods: Thirty patients with thymic hyperplasia, 28 low-risk thymomas, and 13 thymic lymphomas were respectively enrolled.
