"The biggest challenge is there's never a routine": a qualitative study of the time burdens of cancer care at home.
Support Care Cancer
January 2025
Division of Hematology, Oncology, and Transplantation, University of Minnesota, 516 Delaware Street SE, MMC 480, PWB 14-100, Minneapolis, MN, 55455, USA.
Purpose: As cancer care is increasingly delivered in the home, more tasks and responsibilities fall on patients and their informal care partners. These time costs can present significant mental, physical, and financial burdens, and are undercounted in current measures of time toxicity that only consider care received in formal healthcare settings.
Methods: Semi-structured qualitative interviews were conducted with patients with gastrointestinal cancer and informal care partners at a single tertiary cancer center between March and October 2023.
Unexpected cyanobacterial communities in highly heterogeneous toxic blooms from a Mediterranean protected area.

Department of Biology, Universidad Autónoma de Madrid, Madrid, Spain. Electronic address:
The negative effects associated with cyanobacterial blooms are of particular concern in protected ecosystems, as these areas are ecologically significant and attract a high number of visitors. This study aims to explore the cyanobacterial communities and associated toxicity in three reservoirs located within a Mediterranean National Park with a compromised situation at basin-level. Our results demonstrate the occurrence of dense toxic blooms containing microcystins (reaching values close to 280 μg L) and low levels of anatoxin-a and saxitoxins (up to 0.

Chemoresistance is a multifactorial phenomenon and the primary cause to the ineffectiveness of oncotherapy and cancer recurrence. Membrane drug transporters are crucial for drug delivery and disposition in cancer cells. Changes in the expression and functionality of these transporters lead to decreased intracellular accumulation and reduced toxicity of antineoplastic drugs.

Combining polysaccharides with polypeptides enables growth of diverse nanostructures with minimal toxicity, low immune response, and potential biodegradability. However, examples of nanostructures combining polysaccharides with polypeptides are limited due to synthetic difficulties and related issues of solubility, purification, and characterization, with previous reports of polysaccharide-block-polypeptide block copolymers requiring methods such as polymer-polymer coupling and post-polymerization modifications paired with difficult purification steps. Here, we synthesized dextran-block-poly(benzyl glutamate) block copolymers in water via polymerization-induced self-assembly (PISA) to form nanostructures in situ, studying their morphologies using experimental methods and molecular modeling.

Pediatr Blood Cancer
January 2025
Department of Clinical Research, Instituto do Câncer Infantil, Porto Alegre, Brazil.
Background: GALOP investigators developed a prospective cooperative protocol for localized Ewing sarcoma (ES) incorporating interval-compressed chemotherapy (VDC/IE, vincristine, doxorubicin, cyclophosphamide/ifosfamide and etoposide). After completing conventional treatment, patients were randomized to 1 year of metronomic chemotherapy (vinblastine and cyclophosphamide).
Methods: Phase III randomized prospective trial.
