The spleen is the most commonly injured abdominal organ in blunt trauma. Immediate treatment is aimed at assessing for bleeding and abating it when it is severe. Methods for the management of blunt splenic injury-associated bleeding include observation, splenectomy, and splenic salvage procedures through splenorrhaphy or embolization. ⋯ Patients may often present to their primary care provider with complaints related to splenic injury or long-term care of their immunocompromised state. Knowledge of the spleen's function, as well as common complications and risks, is important to physicians caring for splenic injury patients. This narrative review provides clinicians an understanding of the spleen's immune function and management strategies for patients sustaining blunt splenic injury.

Alcohol is a leading cause of liver disease worldwide. Although alcohol abstinence is the crucial therapeutic goal for patients with alcoholic liver disease, these patients have less access to psychosocial, behavioral, and/or pharmacologic treatments for alcohol use disorder. ⋯ In addition to medications approved by the US Food and Drug Administration for alcohol use disorder (disulfiram, naltrexone, and acamprosate), recent efforts to identify potential new treatments have yielded promising candidate pharmacotherapies. Finally, more efforts are needed to integrate treatments across disciplines toward patient-centered approaches in the management of patients with alcohol use disorder and alcoholic liver disease.

Proprotein convertase subtilisin/kexin type 9 inhibitors serve as a valuable addition to the armamentarium of lipid-lowering agents and have promising potential. By inhibiting the proprotein convertase subtilisin/kexin type 9 enzyme, this novel molecule leads to increased low-density lipoprotein receptor density and decreased circulation of low-density lipoprotein. The fact the agent is a monoclonal antibody has led to limited drug interactions and minimized adverse drug events. It is critical for all providers to have a basic understanding of these novel therapies with their introduction and use for treatment.

Direct oral anticoagulants (DOACs) may require dose reduction or avoidance when glomerular filtration rate is low. However, glomerular filtration rate is not usually measured in routine clinical practice. Rather, equations that incorporate different variables use serum creatinine to estimate either creatinine clearance in mL/min or glomerular filtration rate in mL/min/1.73 m2. ⋯ We now highlight these differences and discuss the impact on routine clinical care for anticoagulation to prevent embolization in atrial fibrillation. Pivotal DOAC clinical trials used creatinine clearance as a criterion for patient enrollment, and dose adjustment and Federal Drug Administration recommendations are based on creatinine clearance. However, clinical biochemistry laboratories provide CKD-EPI glomerular filtration rate estimations, resulting in discrepancies between clinical trial and routine use of the drugs.

As expected with all antithrombotic agents, there is a risk of bleeding complications in patients receiving direct oral anticoagulants (DOACs) because of the DOAC itself, acute trauma, invasive procedures, or underlying comorbidities. For many bleeding events, a prudent course of action will be to withdraw the DOAC, then "wait and support" the patient, with the expectation that the bleeding event should resolve with time. Likewise, DOAC therapy may be interrupted ahead of a planned procedure, the stopping time being dependent on the agent involved and the patient's renal function. ⋯ As clinical experience with individual specific reversal agents grows, their roles in managing major bleeding events in DOAC-treated patients will become better defined. Future research, as well as ongoing use of idarucizumab, should help establish when it is appropriate to re-dose with idarucizumab, co-administer with prothrombin complex concentrates, or re-initiate DOAC after idarucizumab use. Ongoing trials should help identify the appropriate doses and expected durations of effect for andexanet alfa and ciraparantag, which are likely to vary depending on the individual oral anticoagulants.
