Background/objectives: Breast cancer is the most common cancer among women globally, and it negatively impacts diet and quality of life, increasing the risk of recurrence. Adhering to World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) lifestyle guidelines, such as healthy eating habits and nutritional status, can help in primary and secondary cancer prevention. However, no questionnaire was found for self-assessment of these guidelines for the Brazilian population.

Background: The long-term effectiveness of immunotherapies against Multiple Myeloma (MM) remains elusive, demonstrated by the inevitable relapse in patients. This underscores the urgent need for an in-depth analysis of the MM tumor-immune microenvironment (TME). Hereto, a representative immunocompetent MM mouse model can offer a valuable approach to study the dynamic changes within the MM-TME and to uncover potential resistance mechanisms hampering effective and durable therapeutic strategies in MM.

Chronic hepatitis B (CHB) infection is influenced by both virological and host factors. A total of 5,920 CHB patients were classified into four groups based on HBV seromarkers: three-generation families (CHB grandmother, mother, and child), two-generation families (CHB mother/child pairs), individuals recovered from HBV infection, and a control group. Serological markers, viral load, liver function tests (LFT), HBV mutations, HLA-DQ variations, cytokine polymorphisms, and liver stiffness measurements (LSM) were analyzed using FibroScan.

Traditional treatment strategies for recurrent pregnancy loss (RPL) and recurrent implantation failure (RIF) often result in limited success, placing significant emotional and financial burdens on couples. However, novel approaches such as diagnostic gene profiling, cell therapy, stem cell-derived exosome therapy, and pharmacogenomics offer promising, personalized treatments. Combining traditional treatments with precision and regenerative medicine may enhance the efficacy of these approaches and improve pregnancy outcomes.

Objectives: Chemotherapy-induced peripheral neuropathy (CIPN) is a significant clinical issue that affects patients' quality of life and can limit the dosing of chemotherapeutic agents. N-acetylcysteine (NAC) has been proposed as a potential chemoprotective agent against CIPN due to its antioxidant properties. This study aimed to investigate the efficacy of oral NAC in preventing and controlling taxane-induced neuropathy in patients with breast cancer.

Global Research Trends on Colorectal Cancer (2014-2023): A Scientometric and Visualized Study.

Arch Iran Med

October 2024

Liver and Pancreaticobiliary Research Center, Digestive Diseases Research Institute, Shariati Hospital, Tehran University of Medical Sciences, Tehran, Iran.

Background: Colorectal cancer (CRC) ranks as the third most common cancer worldwide, significantly contributing to cancer-related deaths and increasingly affecting younger populations. Although its impact on patients' quality of life is profound, scientometric studies on CRC remain underexplored. The objective of this study was to evaluate the scientific literature on CRC from 2014 to 2023, employing a range of scientometric and statistical approaches.

Background: While cardiovascular disease (CVD) polypills have demonstrated significant benefits in preventing CVD events by managing CVD risk factors and improving patient adherence, their effects on blood glucose levels, an important risk factor for CVD, remain unknown.

Methods: We analyzed data from the PolyIran-Liver trial, which involved 1,508 participants aged 50 and above. Of these, 787 were randomly assigned to receive a polypill (consisting of aspirin, atorvastatin, hydrochlorothiazide, and valsartan), while 721 received usual care as the control group over a five-year period.

Article Synopsis
  • SARS-CoV-2 infection severity may be influenced by genetic factors, particularly through the role of platelets and coagulation markers in severe COVID-19 cases.
  • A study of 43 unvaccinated hospitalized COVID-19 patients found significantly higher expression of the platelet-activating factor receptor (PTAFR) and platelet factor 4 (PF4) compared to healthy individuals.
  • The findings suggest that hyperexpression of these genes could serve as important biomarkers for assessing the risk of complications in COVID-19 patients, aiding in personalized treatment approaches.

  • A study assessed the outcomes of patients with pancreatic ductal adenocarcinoma (PDAC) who underwent different types of pancreatic surgeries between 2011 and 2023, including non-vascular resection (NVR), venous resection (VR), and arterial resection (AR).
  • Findings revealed that while initial disease stage did not impact median time to recurrence (TTR) or overall survival (OS), patients who had VR experienced significantly shorter TTR and OS compared to those with NVR and AR.
  • The use of chemotherapy or chemoradiation was found to enhance both TTR and OS, while AR was linked to higher 90-day mortality rates, emphasizing the importance of careful patient selection for this procedure

Current insights and future directions of Li-Fraumeni syndrome.

Discov Oncol

October 2024

Research Center for Integrative Medicine in Aging, Aging Research Institute, Tabriz University of Medical Sciences, Golgasht Street, Tabriz, 51666, EA, Iran.

Li-Fraumeni syndrome is a rare yet serious hereditary cancer predisposition syndrome, marked by a significant early-life increased risk of developing cancer. Primarily caused by germline mutations in the TP53 tumor suppressor gene, Li-Fraumeni syndrome is associated with a wide range of malignancies. Clinical management of Li-Fraumeni syndrome could be challenging, especially the lifelong surveillance and follow-up of patients which requires a multidisciplinary approach.
