AI Article Synopsis

  • Transarterial radioembolization (TARE) using holmium-166 (Ho) is being studied for treating intrahepatic cholangiocarcinoma (ICC), expanding beyond the more commonly used yttrium-90 (Y).
  • A retrospective study of seven ICC patients showed three had a significant response to Ho-TARE, with some achieving stable disease or complete response.
  • The findings suggest Ho-TARE is a safe and effective option that can improve tumor response while focusing on patient quality of life in palliative care settings.

Article Abstract

Background: Transarterial radioembolization (TARE) is used to treat primary and secondary malignancies in the liver that are not amenable to curative resection. Accumulating evidence demonstrates the efficacy and safety of TARE with yttrium-90 (Y), which is the most widely used radionuclide for TARE, and later with holmium-166 (Ho) for various indications. However, the safety and efficacy of Ho TARE in patients with intrahepatic cholangiocarcinoma (ICC) remains to be studied.

Methods: This was a retrospective case series study of seven consecutive patients with ICC who were treated with Ho-TARE in our center. We recorded the clinical parameters and outcomes of the TARE procedures, the tumor response according to mRECIST, subsequent treatments, and adverse events.

Results: Three out of the seven patients had a partial or complete response. Two patients had stable disease after the first TARE procedure, and two of the patients (one with a complete response, and one with stable disease) were alive at the time of analysis. No serious adverse events related to the procedure were recorded.

Conclusions: This is the first case series reporting the safety and tumor response outcomes of Ho-TARE for ICC. The treatment demonstrated its versatility, allowing for reaching a high tumor dose, which is important for improving tumor response and treating patients in a palliative setting, where safety and the preservation of quality of life are paramount.

Introduction: Ankle fractures represent a significant portion of orthopedic injuries, with fracture dislocations tending to have worse outcomes. Logsplitter fractures represent a subset of fracture dislocations in which the talus is axially wedged in the tibiofibular joint. We aim to comprehensively investigate and report on the complications and functional outcomes associated with ankle fracture-dislocations.

Objective: The presence of microorganisms in a wound may lead to the development of pathologically extensive inflammation, and either delay or prevent the healing of hard-to-heal (chronic) wounds. The aim of this case series is to explore the use of topical gentamicin ointment, an aminoglycoside with activity against aerobic Gram-negative bacteria, as an option to address hard-to-heal wounds.

Method: We present a retrospective case series of patients with hard-to-heal wounds of varying pathophysiologies treated with topical gentamicin.

Exudate management is essential for creating a moist wound environment that promotes optimal healing, especially in highly exuding wounds, where choosing an appropriate wound dressing to handle high volumes of exudate is a key part of the wound management strategy. Superabsorbent wound dressings (SWDs) have been designed to absorb and retain large amounts of exudate. Thus, they are advocated for management of wounds with moderate-to-high levels of exudate to reduce the risk of leakage and damage to the periwound skin.

Background: Global aphasia is a severe communication disorder affecting all language modalities, commonly caused by stroke. Evidence as to whether the functional communication of people with global aphasia (PwGA) can improve after speech and language therapy (SLT) is limited and conflicting. This is partly because cognition, which is relevant to participation in therapy and implicated in successful functional communication, can be severely impaired in global aphasia.
