Angiosarcomas are malignant tumors of endovascular origin, which may be divided into primary and secondary forms. Secondary breast angiosarcomas are an increasing problem, especially in patients treated with breast-conserving surgery followed by radiotherapy.We report a case of radiation-induced angiosarcoma of the breast in a 77-year-old woman who presented with a suspect lesion in her left breast. Excisional biopsy and subsequent immunohistochemical staining of the specimen was performed. Histological report was diagnostic for low-intermediate grade angiosarcoma. The tumor cells were diffusely positive for CD31 and CD34. We performed surgical resection with mastectomy.A multidisciplinary approach with bleomycin-based electrochemotherapy, radiation treatment, and chemotherapy with pegylated liposomal doxorubicin has been most useful to control subsequent local relapses. To date, the patient is under close observation and is performing well. No recurrence has been demonstrated after ending of chemotherapy.

HIV-associated neurocognitive disorder (HAND) is a complex neurological complication resulting from human immunodeficiency virus (HIV) infection, affecting about 50% of individuals with HIV and significantly diminishing their quality of life. HAND includes a variety of cognitive, motor, and behavioral disorders, severely impacting patients' quality of life and social functioning. Although combination antiretroviral therapy (cART) has greatly improved the prognosis for HIV patients, the incidence of HAND remains high, underscoring the urgent need to better understand its pathological mechanisms and develop early diagnostic methods.

Background: The increase in severe acute respiratory coronavirus virus 2 (SARS-CoV-2) cases due to the omicron strain led to reduced acute care hospital beds at the Veterans Administration (VA) Hospital, North Texas; veterans with non-severe coronavirus disease 2019 (COVID-19) disease were managed at a community living center (CLC), a VA nursing home. The management of non-severe COVID-19 in VA nursing homes has not been extensively described.
Methods: We describe resident characteristics and outcomes, and infection control practices implemented during 2 COVID-19 outbreak periods (January 12-February 15, 2022, June 28-July 14, 2023).
