The burden of substance abuse among patients with heart failure and its association with subsequent emergency department visits and hospital admissions are poorly characterized. ⋯ Although less prevalent than common medical comorbidities in patients with heart failure, substance-abuse disorders are significant sources of morbidity that are independently associated with emergency department visits and hospitalizations for heart failure. Greater recognition and treatment of substance abuse may improve outcomes among patients with heart failure.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a novel class of medications that reduce plasma glucose concentrations through an insulin-independent mechanism of increased urinary glucose excretion, with concomitant natriuresis and diuresis. Clinical outcomes trials with SGLT2 inhibitors revealed a cardioprotective benefit among patients with diabetes mellitus, with a consistent reduction in hospitalization for heart failure. ⋯ Although well tolerated, there are known adverse effects with SGLT2 inhibitors that require clinical monitoring, such as genital mycotic infections, diabetic ketoacidosis, volume depletion particularly in the setting of concomitant diuretic use, and lower limb amputations with canagliflozin. Ongoing clinical trials will uncover the potential benefit of SGLT2 inhibitors in patients with prevalent heart failure with or without diabetes mellitus.

Risk of Cardiovascular Events in Patients With Type 2 Diabetes and Metabolic Dyslipidemia Without Prevalent Atherosclerotic Cardiovascular Disease.
The relationship between achieved low-density lipoprotein cholesterol (LDL-C) levels and risk of incident atherosclerotic cardiovascular disease events among patients with diabetes and metabolic dyslipidemia has not been well described. ⋯ In a large, contemporary cohort of statin-treated patients with type 2 diabetes and metabolic dyslipidemia without established atherosclerotic cardiovascular disease, lower achieved LDL-C levels were associated with a monotonically lower risk of incident atherosclerotic cardiovascular disease events. The benefits of achieving very-low LDL-C (<50 mg/dL) in this population requires further evaluation in prospective interventional studies.

Patients who have pleural effusions typically undergo thoracentesis with examination of pleural fluid in their initial assessment. However, limited data are available on the diagnostic yield of pleural fluid bacterial cultures and fungal and acid-fast bacilli (AFB) smear and cultures in patients with cancer. ⋯ The incidence of positive results from pleural fluid bacterial, fungal, and AFB in cancer populations is very low. Unless there is a suspicion for infection, microbiological analysis should be ordered selectively.
