There are multiple evidence-based drug treatments for chronic heart failure (HF), both disease-modifying agents and those for symptom control. The majority of the evidence base supports drugs used in HF with reduced left ventricular ejection fraction. The mainstay of disease modification involves manipulation of neurohormonal activation that occurs in HF. ⋯ We aim to provide a comprehensive overview of contemporary drug therapies in chronic heart failure, as well as practical guidance for their use. There is a focus on treating patients with challenging comorbidities such as hypotension and chronic kidney disease (CKD), where a thorough understanding of drug therapy is essential. Multiple trials assessing the benefits of new therapies in HF, such as intravenous iron, are also ongoing.

Bone and joint infections include septic arthritis, prosthetic joint infections, osteomyelitis, spinal infections (discitis, vertebral osteomyelitis and epidural abscess) and diabetic foot osteomyelitis. All of these may present through the acute medical take. This article discusses the pathogenesis of infection and highlights the importance of taking a careful history and fully examining the patient. ⋯ Consideration of alternative diagnoses, appropriate imaging and high-quality microbiological sampling is important to allow appropriate and targeted antimicrobial therapy. This article makes some suggestions as to empiric antibiotic choice; however, therapy should be guided by local antimicrobial policies and infection specialists. Involvement of a multidisciplinary team is essential for optimal outcomes.
