Recurrent Syncope as a Rare Initial Manifestation of Diffuse Large B-Cell Lymphoma in the Cervical Region.

BACKGROUND Diffuse large B-cell lymphoma is the most prevalent form of non-Hodgkin lymphoma, representing around a quarter of newly diagnosed cases of B-cell non-Hodgkin lymphoma. Diffuse large B-cell lymphoma is a disease that affects mostly older persons, with a median presentation in the 7th decade of life. Clinically, it has a variety of presentations, ranging from constitutional symptoms to local or systemic pressure effects caused by a rapidly growing mass.

Short-term exposure to air pollution and hospital admission after COVID-19 in Catalonia: the COVAIR-CAT study.

Background: A growing body of evidence has reported positive associations between long-term exposure to air pollution and poor COVID-19 outcomes. Inconsistent findings have been reported for short-term air pollution, mostly from ecological study designs. Using individual-level data, we studied the association between short-term variation in air pollutants [nitrogen dioxide (NO2), particulate matter with a diameter of <2.

Who is more vulnerable to effects of long-term exposure to air pollution on COVID-19 hospitalisation?

Objective: Factors that shape individuals' vulnerability to the effects of air pollution on COVID-19 severity remain poorly understood. We evaluated whether the association between long-term exposure to ambient NO, PM, and PM and COVID-19 hospitalisation differs by age, sex, individual income, area-level socioeconomic status, arterial hypertension, diabetes mellitus, and chronic obstructive pulmonary disease.

Methods: We analysed a population-based cohort of 4,639,184 adults in Catalonia, Spain, during 2020.

Long-term exposure to air pollution and severe COVID-19 in Catalonia: a population-based cohort study.

The association between long-term exposure to ambient air pollutants and severe COVID-19 is uncertain. We followed 4,660,502 adults from the general population in 2020 in Catalonia, Spain. Cox proportional models were fit to evaluate the association between annual averages of PM, NO, BC, and O at each participant's residential address and severe COVID-19.

A Case of Thymic Carcinoma with Bone and Cerebral Metastases Treated with Stereotactic Radiosurgery and Chemotherapy.

BACKGROUND Thymic carcinoma is a rare malignant neoplasm. High-grade thymic carcinoma has a high recurrence rate following surgery, and a low 5-year survival rate. Approximately 30% of patients with thymic carcinoma will be asymptomatic at the time of diagnosis.

Rapidly Progressing Sporadic Creutzfeldt-Jakob Disease Presenting as a Stroke.

Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare, fatal human prion disease that is characterized by progressive dementia and neurologic degeneration. It can mimic multiple other neurological disorders, and a high index of clinical suspicion is necessary to make a diagnosis. A 74-year-old woman with a 3-month history of a stroke and progressive neurologic deterioration was found to have sCJD.

Evaluation and management of the elderly patient at risk for postoperative delirium.

Geriatric patients are at a high risk for the development of postoperative delirium. By recognizing predisposing and precipitating risk factors, preventive measures can be undertaken to reduce this risk. Accurate and timely diagnosis is essential, and we offer therapeutic strategies to help reduce the high morbidity and mortality of this important condition.
