Article Synopsis
  • * The study included nearly 7,000 patients, revealing that the median heart volume increased over time, and the median mean heart dose (MHD) remained low, indicating effective radiation management.
  • * Findings suggest that, despite an increase in heart volume, the average heart dose during treatment was minimal, demonstrating the feasibility of large-scale audits with automated tools for better patient care.

Article Synopsis
  • This study focused on training a deep learning model to help doctors identify important areas in breast cancer patients that need treatment.
  • It used expert opinions from radiotherapy centers in Denmark to create high-quality data for training the model.
  • The results showed that the model's performance was very similar to what experienced doctors would achieve, which means it could be used safely in real medical situations.

Diets, but also overall food environments, comprise a variety of significant factors with direct and indirect impacts on human health. Eco-Regions are geographical areas with a territorial approach to rural development, utilizing organic food and farming practices, and principles and promoting sustainable communities and food systems. However, so far, little attention has been given to quantifying aspects of the health of citizens living in these sustainable transition territories.

Diets influence our mental health and social wellbeing (MHSW) in multiple ways. A rising community concept, Eco-Regions, has gained interest. The research project "Indicators for assessment of health effects of consumption of sustainable, organic school meals in Ecoregions" (INSUM) aims to develop future-oriented research approaches to measure the potential health effects of more sustainable and healthy diets.

Antimicrobial resistance (AMR) decreases the effectiveness of antimicrobials to treat bacterial infections in humans and animals. The increased occurrence of AMR in bacterial population in humans, animals, and the environment requires the measures to combat a rising global health crisis. The aim of this research was to present current knowledge on AMR in a system map and to identify potential explanations of former identified variables significantly associated with AMR.

Purpose: The Danish Breast Cancer Group Internal Mammary Node study demonstrated improved 8-year overall survival (OS) with internal mammary node irradiation (IMNI) in patients with node-positive early breast cancer. Here, we present long-term results from the Danish Breast Cancer Group Internal Mammary Node study cohort.

Patients And Methods: This nationwide, prospective cohort study allocated patients with node-positive early breast cancer to adjuvant radiotherapy with or without IMNI depending on cancer laterality.

Breast cancer is the most common cancer diagnosed in women, and early stages are treated with lumpectomy and irradiation. Irradiation, however, leads to reduced vascularization and fibrosis, which may influence the cosmetic outcome unfavourably and increase complications after subsequent surgery on irradiated breasts. Patients with significant asymmetry after treatment may desire corrective reduction mammoplasty or mastopexy, but this may be associated with increased complication rates.

Radiation is considered to be a risk factor for developing capsular contracture in augmented women, but the studies reporting on this subject show conflicting results. In this systematic review we sought to understand the risk of capsular contracture in augmented patients with breast cancer treated with breast conserving surgery and radiotherapy. A search was conducted through PubMed for studies reporting on breast cancer, breast augmentation and radiotherapy, with capsular contracture as our primary outcome.

Influenza virus infections are a major public health threat. Vaccination is available, but unpredictable antigenic changes in circulating strains require annual modification of seasonal influenza vaccines. Vaccine effectiveness has proven limited, particularly in certain groups, such as the elderly.

The Innovative Medicines Initiative is a public-private partnership between the European Union and the pharmaceuticals industry that was established in 2008, with an overall budget of €5.3 billion from 2008 until 2024. The objective of the initiative is to boost pharmaceutical innovation in Europe and speed up the development of innovative medicines, vaccines and medical technologies, in particular in areas with high unmet needs.

Background: Cutaneous recurrence from breast cancer can pose a clinical challenge. It might be the only disease site, or could be part of disseminated disease, and often profoundly affects quality of life. Electrochemotherapy is a palliative treatment using electric pulses to locally permeabilize tumor cells and thereby significantly increase bleomycin cytotoxicity.

Electrochemotherapy is now in routine clinical use to treat cutaneous metastases of any histology, and is listed in national and international guidelines for cutaneous metastases and primary skin cancer. Electrochemotherapy is used by dermatologists, surgeons, and oncologists, and for different degrees and manifestations of metastases to skin and primary skin tumours not amenable to surgery. This treatment utilises electric pulses to permeabilize cell membranes in tumours, thus allowing a dramatic increase of the cytotoxicity of anti-cancer agents.

Background: Calcium electroporation is a novel anticancer treatment, which utilizes high voltage pulses to permeabilize cell membranes and expose the cell to supraphysiological doses of calcium. Preclinical studies on calcium electroporation have shown strikingly high tumor response with cell necrosis. Calcium electroporation builds on the treatment electrochemotherapy, where chemotherapeutic drugs, mostly bleomycin, are internalized by electroporation.

Immunisation efforts save millions of lives every year, but vaccines hold the potential to deliver even greater health benefits for mankind. Vaccine research and development is highly complex, and it requires concerted public funding efforts to support. In this paper we discuss EU funding priorities and the resulting recent advancements in European vaccine research, and we lay out the EU strategy for aiding promising vaccine candidates to successfully reach the market.

Cutaneous metastases occur in up to 9% of all patients with cancer and may cause discomfort and stigmatization. Electrochemotherapy is a local treatment using electric pulses to permeabilize cell membranes, enabling chemotherapy, such as bleomycin, to enter the cells and increase the cytotoxic effect by at least 300-fold. Electrochemotherapy is an efficient, once only treatment for cutaneous metastases with an objective response of 62-99%.

Background: Electrochemotherapy describes the use of electric pulses to enhance chemotherapy uptake, and has proven highly efficient in treating cutaneous metastases. Patients referred for electrochemotherapy present with diverse clinical pictures, from multiple small lesions to large, ulcerated lesions. Post-electrochemotherapy pain has been observed in some patients.

Background: Electrochemotherapy is a local anticancer treatment very efficient for treatment of small cutaneous metastases. The method is now being investigated for large cutaneous recurrences of breast cancer that are often confluent masses of malignant tumour with various degrees of inflammation. To this end 18-Flourine-Flourodeoxyglucose-Positron Emission Tomography/Computed Tomography (FDG-PET/CT) could be a method for response evaluation.

Background: Cutaneous recurrences of breast cancer may cause considerable discomfort due to ulceration, oozing, and pain and can also be difficult to treat. Electrochemotherapy is a localised anticancer treatment using electric pulses to make cell membranes permeable, augmenting uptake of chemotherapeutic drugs, and thus enabling highly efficient tumour cell kill. This is the first systematic investigation of electrochemotherapy for larger cutaneous recurrences of breast cancer.

Background: Cutaneous metastases may cause considerable discomfort as a consequence of ulceration, oozing, bleeding and pain. Electrochemotherapy has proven to be highly effective in the treatment of cutaneous metastases. Electrochemotherapy utilises pulses of electricity to increase the permeability of the cell membrane and thereby augment the effect of chemotherapy.
