Background: Patients diagnosed with radioiodine refractory (RAI-R) thyroid carcinoma (TC) have a significantly worse prognosis than patients with radiosensitive TC. These refractory malignancies are often dedifferentiated, hindering the effectiveness of iodine-based imaging. Additionally, the role of metabolic imaging using [F]FDG PET/CT is also limited in these cases, making adequate staging of RAI-R TC challenging.

Interprofessional communication is crucial for patient care, yet there is a dearth of comprehensive assessment tools essential to train and assess healthcare students. While the Interprofessional Educational Collaborative framework (IPEC) outlines eight sub-competencies, it lacks detailed behavioral indicators. This study aimed to create a repository of interprofessional communication behaviors to complement the IPEC sub-competencies.

Purpose: Intestinal-type adenocarcinoma (ITAC) is a rare sinonasal malignancy. Curative treatment requires multidisciplinary approach, with surgical options consist of the endonasal endoscopic approach (EEA) and external surgery (EXTS). Here, we provide the post-operative and survival results from a single-center long-term follow-up.

Article Synopsis
  • Surgical resection is crucial for treating various cancers, aiming for the complete removal of tumors and preventing relapse, which can negatively affect survival and quality of life.
  • Fluorescence imaging enhances surgical outcomes by allowing surgeons to visualize malignant tissues through the use of fluorescent contrast agents, particularly utilizing Nanobodies (Nbs) that target specific tumor markers like the epidermal growth factor receptor (EGFR).
  • A preliminary study in healthy dogs demonstrated that the fluorescently labeled anti-EGFR Nb 7D12-s775z was well tolerated without adverse effects, with encouraging imaging results suggesting rapid clearance, supporting further investigations in cancer treatments.

Purpose: Recent technical advancements in PET imaging have improved sensitivity and spatial resolution. Consequently, clinical nuclear medicine will be confronted with PET images on a previously unfamiliar resolution. To better understand [F]FDG distribution at submillimetric scale, a direct correlation of radionuclide-imaging and histopathology is required.

Purpose: A cornerstone of treatment for many cancers is the administration of platinum-based chemotherapies and/or ionizing radiation, which can be ototoxic. An accurate ototoxicity risk assessment would be useful for counseling, treatment planning, and survivorship follow-up in patients with cancer.

Methods: This systematic review evaluated the literature on predictive models for estimating a patient's risk for chemotherapy-related auditory injury to accelerate development of computational approaches for the clinical management of ototoxicity in cancer patients.

Purpose: Platinum-based chemotherapies used to treat many types of cancers are ototoxic. Ototoxicity management (OtoM) to mitigate the ototoxic outcomes of cancer survivors is recommended practice yet it is not a standard part of oncologic care. Although more than 10,000 patients each year are treated with platinum-based chemotherapies at the US Veterans Health Administration (VA), the current state of OtoM in VA is not well-defined.

Over 27 million people worldwide currently receive daily antiretroviral therapy for the management of HIV/AIDS. In order to prevent the continued spread of HIV, the World Health Organization (WHO) recommends the use of highly active antiretroviral therapy by pregnant and nursing women. There is currently little research into the auditory effects of this therapy on children exposed during pregnancy and breastfeeding, and research to date on the direct effects of antiretroviral exposure on the auditory system is inconclusive.

Objective: There is evidence of ototoxicity from antiretrovirals (ARVs), and ARV therapy in pregnant/nursing mothers can expose offspring to these compounds. The current work modelled whether exposure to ARVs and during nursing altered the functioning of the auditory system in offspring mice.

Design: The females of seven breeding pairs of C57BL6/J mice were given daily doses of ARVs lamivudine and tenofovir disoproxil fumarate by oral gavage during gestation and nursing.

The surgical treatment of head and neck malignancies relies on the complete removal of tumoral tissue, while inadequate margins necessitate the use of adjuvant therapy. However, most positive margins are identified postoperatively as deep margins, and intraoperative identification of the deep positive margins could help achieve adequate surgical margins and decrease adjuvant therapies. To improve deep-margin identification, we investigated whether the use of high-resolution preclinical PET and CT could increase certainty about the surgical margins in three dimensions.

An increased presence of CD206-expressing tumor associated macrophages in solid cancers was proposed to be associated with worse outcomes in multiple types of malignancies, but contradictory results are published. We performed a reproducible systematic review and meta-analysis to provide increased evidence to confirm or reject this hypothesis following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The Embase, Web of Science, and MEDLINE-databases were systematically searched for eligible manuscripts.

Acquired sensorineural hearing loss is a major public health problem worldwide. The leading causes of sensorineural hearing loss are noise, aging, and ototoxic medications, with the key underlying pathology being damage to the cochlea. The review focuses on the phenomenon of preconditioning, in which the susceptibility to cochlear injury is reduced by exposing the ear to a stressful stimulus.

Background: Chronic neuropathic pain is a condition affecting an increasing proportion of the general population and its management requires a comprehensive, multidisciplinary program. A growing body of evidence supports the use of hyperbaric oxygen therapy (HBOT) in several chronic neuropathic pain conditions; however, its role and efficacy remain unclear.

Purpose: To summarize current evidence for the mechanistic rationale of HBOT in chronic neuropathic pain conditions and to evaluate its clinical efficacy.

Objective: The prevailing approaches to selecting multiple sclerosis (MS) disease modifying therapies (DMTs) have contributed to exponential increases in societal expenditures and out-of-pocket expenses, without compelling evidence of improved outcomes. Guidance is lacking regarding when and in whom the benefits of preventing MS-related disability likely outweighs the risks of highly effective DMTs (HET) and when it is appropriate to consider DMT costs. Our objective was to develop a standardized approach to improve the quality, affordability and equity of MS care.

Various methods have been tested and deployed clinically to identify and minimize cisplatin ototoxicity. Upon early identification of hearing loss, one of the possible approaches to reducing future ototoxicity is to increase the gaps or breaks between cycles or doses of cisplatin. However, recent findings about the retention of cisplatin in the cochlea and the potential for its long-term ototoxic effects call into question whether such an approach is effective in reducing hearing loss.
