Unlabelled: Combining therapeutic with diagnostic agents (theranostics) can revolutionize the course of malignant diseases. Chemotherapy, hyperthermia, or radiation are used together with diagnostic methods such as magnetic resonance imaging (MRI). In contrast to conventional contrast agents (CAs), which only enable non-specific visualization of tissues and organs, the theranostic probe offers targeted diagnostic imaging and therapy simultaneously.

Article Synopsis
  • Amino-dextrans (AD) conjugated with gadolinium (Gd) were created as contrast agents for visualizing sciatic nerves in rats using MRI, with different molecular weights tested for their transport efficiency.
  • Advanced techniques such as FPLC, SDS-PAGE, and ICP-MS were employed to analyze the properties of these contrast agents, incorporating stable chelators like DOTA to enhance MRI signal.
  • The study successfully tracked the movement of AD-DTPA-Gd in the sciatic nerve over seven days, revealing its potential for diagnosing and monitoring nerve injuries by demonstrating active transport to the spinal cord.

Article Synopsis
  • Ewing sarcoma (ES) and osteosarcoma (OSA) are common bone tumors in young adults, with treatment involving chemotherapy and surgery; this study assessed the EURAMOS-A and EURO E.W.I.N.G. protocols.
  • A total of 31 patients aged 18 to 39 were analyzed, revealing that most ES cases were localized in the thorax or pelvis, while OSA typically affected the lower extremities; a significant proportion required dose reductions during treatment.
  • Both treatment protocols proved to be well-tolerated, suggesting that dose reductions for side effects may be more beneficial than delaying doses in these patients.

Front Med (Lausanne)

December 2020

Clinical Laboratory for Bionic Extremity Reconstruction, Division of Plastic and Reconstructive Surgery, Department of Surgery, Medical University of Vienna, Vienna, Austria.

Article Synopsis
  • Current imaging methods show the structure of peripheral nerves but not their function; a new approach using contrast agents may help visualize nerve activity.
  • This study tested MRI with gadolinium-based contrast agents to track nerve function by observing their distribution after axonal transport in rats.
  • Results indicated that specific contrast agents significantly enhanced MRI signals in the sciatic nerve and spinal cord, suggesting potential for improved diagnosis and treatment of nerve injuries.

Improved clinical care has led to an increase in the number of adults with congenital heart disease (CHD) engaging in leisure time and competitive sports activities. Although the benefits of exercise in patients with CHD are well established, there is a low but appreciable risk of exercise-related complications. Published exercise recommendations for individuals with CHD are predominantly centred on anatomic lesions, hampering an individualized approach to exercise advice in this heterogeneous population.

The Italian College of Breast Radiologists by the Italian Society of Medical Radiology (SIRM) provides recommendations for breast care provision and procedural prioritization during COVID-19 pandemic, being aware that medical decisions must be currently taken balancing patient's individual and community safety: (1) patients having a scheduled or to-be-scheduled appointment for in-depth diagnostic breast imaging or needle biopsy should confirm the appointment or obtain a new one; (2) patients who have suspicious symptoms of breast cancer (in particular: new onset palpable nodule; skin or nipple retraction; orange peel skin; unilateral secretion from the nipple) should request non-deferrable tests at radiology services; (3) asymptomatic women performing annual mammographic follow-up after breast cancer treatment should preferably schedule the appointment within 1 year and 3 months from the previous check, compatibly with the local organizational conditions; (4) asymptomatic women who have not responded to the invitation for screening mammography after the onset of the pandemic or have been informed of the suspension of the screening activity should schedule the check preferably within 3 months from the date of the not performed check, compatibly with local organizational conditions. The Italian College of Breast Radiologists by SIRM recommends precautions to protect both patients and healthcare workers (radiologists, radiographers, nurses, and reception staff) from infection or disease spread on the occasion of breast imaging procedures, particularly mammography, breast ultrasound, breast magnetic resonance imaging, and breast intervention procedures.

Purpose: Current incidence methods for reporting mild or moderate symptoms capture the (first) occurrence of an event and do not allow distinguishing between patients who suffer from long-lasting versus transient morbidity. This paper introduces a new methodological approach that identifies cancer survivors who have clinically relevant, long-lasting symptoms (patients with late, persistent, substantial and treatment-related symptoms, [LAPERS]).

Methods And Materials: LAPERS can be evaluated in patients with baseline information and at least 3 late follow-up assessments after treatment.
