The incidence and prognosis of renal dysfunction following cardioversion of atrial fibrillation.

Objective: Limited data are available regarding the incidence and clinical impact of renal dysfunction following cardioversion of atrial fibrillation. The objective of this study was to assess the incidence and implications of renal dysfunction following cardioversion of atrial fibrillation.

Methods: We conducted a nested case-control study to determine the incidence, timing, risk factors and outcome of atrial fibrillation cardioversion associated with renal dysfunction (AFCARD) in a tertiary medical center.

Autologous stem cell transplantation in a rare multicentric Castleman disease of the plasma cell variant.

We present a case of a 52-year-old male who was evaluated due to anorexia, persistent diarrhea, weight loss, and liver enzyme elevations, with no hematologic laboratory abnormalities. Imaging modalities revealed several tissue lesions involving the pancreas, the right kidney, and an axillary lymph node. Diagnosis of Castleman disease was reached only due to the tissue obtained from the lymph node.

Factors associated with bleeding in elderly hospitalized patients treated with enoxaparin sodium : a prospective, open-label, observational study.

Background: Despite a lack of clear recommendations to guide decision-making, reductions in enoxaparin sodium dosage in the elderly and in patients with mild and moderate renal dysfunction are common in patients with acute coronary syndrome.

Objective: To evaluate whether weight, age and renal function are associated with anti-factor Xa activity and with bleeding in elderly patients treated with enoxaparin sodium.

Method: This was a prospective observational study of 156 elderly patients admitted consecutively to a general internal medicine ward with creatinine clearance >30 mL/min who were treated with enoxaparin sodium twice daily.

[Air pollution and cardiovascular disease].

Cardiovascular atherothrombosis is the most common cause of death globally, with several well-known risk factors. Air pollution is a byproduct of fuel combustion by motor vehicles, power plants and industrial factories. It is composed of gases, fluids and particulate matter (PM) of different sizes, which include basic carbon, organic carbonic molecules and metals such as vanadium, nickel, zinc and iron.
