Androgen receptor (AR)-negative triple-negative breast cancer (TNBC), often termed quadruple-negative breast cancer (QNBC), disproportionately impacts women of African descent, leading to poorer overall survival (OS). MiRNAs regulate the expression of gene drivers involved in critical signaling pathways in TNBC, such as the gene, and their expression varies across races and breast cancer subtypes. This study investigates whether differentially expressed miRNAs influence AR transcription, potentially contributing to the observed disparities between African American (AA) and European American (EA) QNBC patients.

Article Synopsis
  • A study was conducted to explore patient experiences of chronic postoperative pain and its management after pelvic exenteration for locally recurrent rectal cancer, using one-on-one phone interviews with 17 patients.
  • The main findings revealed three key themes: the need to adapt to long-term pain consequences, a reluctance to use pain medications, and the importance of a multidisciplinary care team for effective pain management.
  • Limitations include a small sample size from a single center, making it difficult to generalize the results to all patients undergoing similar procedures.

Human papillomavirus (HPV) is involved in virtually all cases of cervical cancer. However, HPV alone is not sufficient to cause malignant development. The effects of chronic inflammation and the interaction of immune components with the microenvironment infected with the high-risk HPV type (HR) may contribute to cancer development.

Background: There are limited data on the physical effects of androgen deprivation therapy (ADT) for prostate cancer (PC), and on the relationships of such measures of adiposity and strength to cardiovascular outcomes.

Objectives: The primary objective of this study was to evaluate the relationships of measures of adiposity and strength to cardiovascular outcomes (cardiovascular death, myocardial infarction, stroke, heart failure, arterial revascularization, peripheral arterial disease, and venous thromboembolism) in patients with PC. A secondary objective was to characterize the relationships between ADT use and 12-month changes in these physical measures.

  • - The Brazilian Rare Diseases Network (RARAS) was established in 2020 to conduct a nationwide epidemiological survey on rare diseases (RDs) in Brazil, addressing the lack of comprehensive national data since the Comprehensive Care Policy for RDs began in 2014.
  • - A total of 12,530 patients were surveyed, with a median age of 15 years; significant findings included that 63.2% had confirmed diagnoses, primarily of phenylketonuria, cystic fibrosis, and acromegaly, and average diagnostic delays lasting 5.4 years.
  • - The majority of diagnoses and treatments were funded by the Public Health System, with notable rates of hospitalization (44.5%) and a mortality rate

Triple-negative breast cancer (TNBC), characterized by high invasiveness, is associated with poor prognosis and elevated mortality rates. Despite the development of effective therapeutic targets for TNBC, systemic chemotherapy and radiotherapy (RdT) remain prevalent treatment modalities. One notable challenge of RdT is the acquisition of radioresistance, which poses a significant obstacle in achieving optimal treatment response.

Article Synopsis
  • A study analyzed methanolic extracts from fifteen ethnomedicinal plants in Mexico to explore their medicinal properties, focusing on biological activities including anti-hemolytic, antioxidant, and cytotoxic effects in normal cells.
  • The extracts were tested for hemolytic activity on human red blood cells, their protective ability against certain radicals, and their toxicity in cell cultures of African green monkey kidney cells and peripheral blood mononuclear cells using the MTT reduction method.
  • Results indicated that most extracts had low hemolytic activity but significant anti-hemolytic and antioxidant effects, with select extracts promoting cell proliferation, suggesting that these traditional plants have beneficial health properties worthy of further research.

Article Synopsis
  • Cardiovascular diseases are a big problem around the world, and clinical trials help find better treatments for them.
  • Conflicts of interest (COIs), which can happen when companies have a say in research, can affect how trials are carried out and the results they show.
  • It's important to be careful about COIs in studies because they can change guidelines that doctors follow, and sharing rules and being open about research can help keep everyone’s trust in the science.

Importance: Nearly half the patients transferred from nontrauma centers to trauma centers have minor injuries, yet trauma center care is not associated with a difference in morality among patients with minor injuries. Consequently, reducing the frequency of such transfers has been postulated as a method to improve resource allocation. Currently, the economic implications of these transfers are not well understood.

ASTCT Consensus Recommendations on Testing and Treatment of Patients with Donor-specific Anti-HLA Antibodies.

December 2024

Hematopoietic Stem Cell Transplant and Cellular Therapy Program, Division of Hematology and Oncology, Department of Medicine, Chao Family Comprehensive Cancer Center, University of California Irvine, Irvine, CA, USA. Electronic address:

Donor-specific anti-HLA antibodies (DSA) are an important cause of engraftment failure and may negatively impact survival outcomes of patients receiving allogeneic hematopoietic stem cell transplantation (HSCT) using an HLA-mismatched allograft. The incidence of DSA varies across studies, depending on individual factors, detection or identification methods and thresholds considered clinically relevant. Although DSA testing by multiplex bead arrays remains semiquantitative, it has been widely adopted as a standard test in most transplant centers.

Up to 70% of patients with Wiskott-Aldrich syndrome (WAS) develop autoimmune and inflammatory manifestations. Dysregulation of interleukin 1 (IL-1) may be involved in their pathogenesis, yet there is little evidence on treatment with anti-IL-1 agents in these patients. We conducted a multicenter retrospective analysis of 9 patients with WAS treated with anti-IL-1 agents (anakinra or canakinumab).

MiRNAs, a class of non-coding RNA molecules, have emerged as critical modulators of telomere length and telomerase activity by finely tuning the expression of target genes (and not gene targets) within signaling pathways involved in telomere homeostasis. The primary objective of this systematic review was to compile and synthesize the existing body of knowledge on the role, association, and involvement of miRNAs in telomere length. Additionally, the review explored the regulation, function, and activation mechanism of the human telomerase reverse transcriptase (hTERT) gene and telomerase activity in tumor cells.

Preserving isohydricity: vertical environmental variability explains Amazon forest water-use strategies.

Tree Physiol

August 2024

Department of Ecology and Evolutionary Biology, University of Arizona, 1200 E University Blvd, Tucson, AZ 85721, United States.

Increases in hydrological extremes, including drought, are expected for Amazon forests. A fundamental challenge for predicting forest responses lies in identifying ecological strategies which underlie such responses. Characterization of species-specific hydraulic strategies for regulating water-use, thought to be arrayed along an 'isohydric-anisohydric' spectrum, is a widely used approach.

This study aims to evaluate and compare cellular therapy with human Wharton's jelly (WJ) mesenchymal stem cells (MSCs) and neural precursors (NPs) in experimental autoimmune encephalomyelitis (EAE), a preclinical model of Multiple Sclerosis. MSCs were isolated from WJ by an explant technique, differentiated to NPs, and characterized by cytometry and immunocytochemistry analysis after ethical approval. Forty-eight rats were EAE-induced by myelin basic protein and Freund's complete adjuvant.
