AI Article Synopsis

  • Immune checkpoint inhibitors (ICIs) used in cancer treatment are linked to an increase in cardiovascular adverse events (CVAE), including conditions like myocarditis and heart failure.
  • These cardiovascular side effects are thought to result from inflammation and immune system imbalances triggered by immunotherapy.
  • Effective management of ICI-related CVAEs often involves steroids and other medications, but there is a lack of comprehensive studies on the cardiovascular safety of ICIs, relying mostly on limited case reports for treatment guidance.

Article Abstract

Immune checkpoint inhibitor (ICI) associated cardiovascular adverse events (CVAE) have become more frequent with the growing use of cancer immunotherapy. CVAEs include a wide spectrum of diseases such as myocarditis, pericarditis, heart failure, arrhythmias, coronary artery disease, and hypertension. The induction of cardiovascular side effects by ICI use is hypothesized to occur due to inflammation and immune dysregulation of normal tissue in response to immunotherapy. Management of ICI-associated CVAEs mitigates an overactive immune response by utilizing steroids, immunomodulatory drugs and hemodynamic stabilization. However, few controlled studies on the cardiovascular safety of ICIs exist and treatment of their side effects are mostly from limited case series. Our review seeks to provide the most recent understanding of ICI-associated CVAEs and their management.

Metabolic syndrome during menopause can lead to diabetes, cardiovascular problems, and increased mortality rates. Hormone replacement therapy is recommended to manage climacteric complications, but it has serious adverse effects. This study, therefore, investigated the potential of supplementing some minerals, vitamins, and natural products like boric acid, magnesium, vitamin D3, and extra virgin olive oil on metabolic status of menopausal ovariectomized rats.

Protein hydrolysis targeted chimeras (PROTACs) represent a different therapeutic approach, particularly relevant for overcoming challenges associated with traditional small molecule inhibitors. These challenges include targeting difficult proteins that are often deemed "undruggable" and addressing issues of acquired resistance. PROTACs employ the body's own E3 ubiquitin ligases to induce the degradation of specific proteins of interest (POIs) through the ubiquitin-proteasome pathway.

Department of Medical Oncology, Hebei Key Laboratory of Cancer Radiotherapy and Chemotherapy, Affiliated Hospital of Hebei University, 212 Yuhua East Road, Baoding, 071000, Hebei, China.

The first-line treatment for chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) has recently undergone major changes, and targeted therapies have ushered in a new era of CLL/SLL treatment. Scientists in different countries have successively analyzed the efficacy of various drugs, but safety studies are relatively insufficient. Therefore, this systematic evaluation and retrospective meta-analysis was conducted to compare the differences in adverse effects and their incidence among first-line treatment regimens for CLL/SLL.

Background: Despite constant improvements, incontinence is one of the most relevant and quality-of-life-reducing side effects of radical prostatectomy (RP) and, in addition to patient-specific factors such as age, the experience of the surgeon/center and the surgical technique used play an important role.

Aims: To present current real-world data on short-term incontinence after RP from one of the largest German rehabilitation centers in 2022 and to compare it to the results from the same institution in 2016.

Methods And Results: Retrospective, unicentric, univariate analysis of data from 1394 men after RP in 2022 on admission and discharge from the rehabilitation clinic.
