Radiation doses to the breast and predicted breast cancer risk among patients treated for Hodgkin lymphoma with modern radiotherapy.

Purpose: To contrast breast radiation exposure from chest radiotherapy in 2006-2021 with 1965-1997, and to compare breast cancer (BC) risk 25 years after treatment predicted by two models.

Methods: Radiation dose distributions to the breast from 101 chest radiotherapies given 2006-2021 for Hodgkin lymphoma (HL) or other lymphoma in one German and two Dutch hospitals were compared with doses received by 505 Dutch HL patients treated 1965-1997 and sampled into a nested case-control study, weighted to represent a HL patient cohort. Dose-volume histograms, mean dose and doses to 10 breast segments were evaluated.

Mutation in and a Variant Linked to a Severe Sporadic Infant Dilated Cardiomyopathy Case.

Structural or electrophysiologic cardiac anomalies may compromise cardiac function, leading to sudden cardiac death (SCD). Genetic screening of families with severe cardiomyopathies underlines the role of genetic variations in cardiac-specific genes. The present study details the clinical and genetic characterization of a malignant dilated cardiomyopathy (DCM) case in a 1-year-old Mexican child who presented a severe left ventricular dilation and dysfunction that led to SCD.

Mortality Trends and Causes of Death in Myotonic Dystrophy Type 1 Patients From the UK Clinical Practice Research Datalink.

Introduction/aim: Patients with myotonic dystrophy type1 (DM1) have reduced lifespan. This study aimed to quantify mortality risks, and evaluate causes and time trends in DM1.

Methods: We identified 1021 DM1 patients and 15,104 matched DM1-free controls from the United Kingdom (UK) Clinical Practice Research Datalink.

Characterization of mammographic markers of inflammatory breast cancer (IBC).

Purpose: Inflammatory breast cancer (IBC) is a rare and aggressive type of breast cancer, as many physicians may not be aware of it in terms of symptoms and diagnosis. Mammography is the first choice in breast screenings and diagnosis. Because of a lack of expertise and imaging datasets, IBC portrayal and machine learning-based diagnosis systems have not yet been studied thoroughly.

Merkel Cell Carcinoma and Immunosuppression, UV Radiation, and Merkel Cell Polyomavirus.

Importance: Merkel cell carcinoma (MCC) is a rare but aggressive skin cancer. Quantifying the contribution of major potentially modifiable risk factors to the burden of MCC may inform prevention efforts.

Objective: To estimate the population attributable fraction of MCC cases in the US that were attributable to major immunosuppressing conditions (eg, HIV, solid organ transplant, chronic lymphocytic leukemia [CLL]), ambient UV radiation [UVR] exposure, and Merkel cell polyomavirus [MCPyV]).
