Heart failure (HF) affects more than 6 million adults in the United States, contributing to substantial morbidity, mortality, and health care costs. Despite advances in medical care, many medications can exacerbate HF, yet their prevalence of use remains unknown. This study examined the national use of prescription medications that could exacerbate HF in adults with self-reported HF.

The use of serum creatinine (SCr) for drug dosing has significant limitations and is influenced by many non-kidney factors. Cystatin C (cysC) is an alternative or additional marker of kidney function that is less affected by non-kidney factors. Although cysC may be useful in hospitalized patients, the use of cysC to calculate drug dosing in critically ill patients has been incompletely investigated.

Osteoarthritis (OA) is the most common form of arthritis, affecting over 500 million people globally. Current treatments are primarily symptom-focused, with no approved therapies to halt disease progression. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), widely used in type 2 diabetes (T2D) and obesity, demonstrate significant weight loss and glucose-lowering effects and have been shown to possess anti-inflammatory properties. Given the central role of inflammation and metabolic dysfunction in OA, this review examines the potential utility of GLP-1 RAs in OA management, focusing on both indirect effects, such as weight reduction, and possible direct effects on inflammatory pathways and cartilage preservation. Clinical studies suggest that GLP-1 RAs may benefit people with OA by reducing weight, improving glycemic control, and modulating inflammatory markers relevant to OA progression. Notable findings include significant weight loss and pain reduction in people with knee OA (KOA) treated with semaglutide in the STEP-9 trial. In other studies, GLP-1 RAs have shown potential to lower oxidative stress and pro-inflammatory cytokines, such as tumor necrosis factor (TNF-α) and interleukin (IL)-6, with reductions in OA-related pain and functional impairment observed in some cohorts. However, results vary, with some studies showing limited effects, potentially linked to the degree of weight loss achieved. Although some studies report variability in pain relief, likely influenced by the degree of weight loss achieved, GLP-1 RAs have shown overall promise in reducing both OA symptoms and markers associated with disease progression. This emerging evidence supports the utility of GLP-1 RAs as a potential disease-modifying option for OA, offering a dual benefit in metabolic and joint health. Future research should focus on establishing the long-term efficacy and safety and elucidating the mechanism by which GLP-1 RAs influence OA pathology.

HIV has been shown to persist in the central nervous system (CNS) in persons on antiretroviral therapy (ART). Our objective was to use pharmacokinetic (PK) modeling to estimate cerebrospinal fluid (CSF) exposure from time-variant concentrations of various antiretrovirals of ART regimens and to standardize CSF metrics, including maximum concentration [C], area under the curve [AUC], and trough [C].

Hyponatremia is a common electrolyte disorder among older adults that can cause serious adverse effects. The purpose of this study was to assess the risk of hyponatremia with the concurrent use of selective serotonin reuptake inhibitors (SSRIs) and thiazide diuretics in an older population.

The prevalence of exposure to supratherapeutic doses or contraindicated medications based on renal dosing criteria, also known as potentially inappropriately prescribed medications (PIPM), is currently unknown among patients on peritoneal dialysis (PD). The primary objective of this study was to evaluate the prevalence of PIPM in the first year of PD among Medicare patients in the United States.

Antibiotics constitute the majority of prescriptions for women during pregnancy. Common bacterial infections, including urinary tract infections, skin and soft tissue infections, and upper and lower respiratory tract infections, are expected in pregnancy, similar to the general public. These infections carry additional risks to both the woman and fetus; thus, antibiotics are often prescribed. Antibiotics, like other drugs, are not benign and may carry additional risks to the fetus beyond commonly encountered adverse drug events seen across most patient populations. Since 2014, 19 new antibiotics have been approved by the United States Food and Drug Administration. Additionally, in 2018, the previously held pregnancy category rating expired, and all manufacturers' labeling was updated with new narrative language reflecting safety in pregnancy, lactation, and males and females of reproductive potential. This review provides a comprehensive summary of available data and an update to the 2015 publication regarding the safe use of antibiotics in pregnancy. The primary focus of this review is on newly approved antibiotics, along with any additional published evidence on previously reviewed antibiotics. Data on lactation or antiviral or antifungal use in pregnancy are not included. Clinicians should remain updated on current available evidence and vigilant to provide safe and effective antibiotic decision-making in pregnant women.

With recent clinical implementation of tirzepatide, patients with type 2 diabetes mellitus (T2DM) are transitioning from glucagon-like peptide 1 receptor agonists (GLP-1 RA) to a dual gastric inhibitory polypeptide (GIP)/GLP-1 RA-like tirzepatide. Limited literature is available for insulin dose adjustments for patients concurrently using insulin during this transition. In clinical trials, tirzepatide has shown greater glycated hemoglobin (A1c) reduction and glucose-lowering effects compared to GLP-1 RAs, such as semaglutide, suggesting a potential elevated risk of hypoglycemia without proactive insulin adjustments.

Vancomycin guidelines recommend area-under-the-curve (AUC) therapeutic monitoring for patients with severe methicillin-resistant Staphylococcus aureus (MRSA) infections. No recommendations exist for patients with non-severe staphylococcal infections or those with other Gram-positive infections. AUC-based vancomycin dosing can be resource-intensive and may not be necessary for all patients.

Clozapine and risperidone are second-generation antipsychotics used in the treatment of schizophrenia. There are no guidelines on cross-titration of antipsychotics and, additionally, there is a paucity of published data to support the potential utility of using serum drug levels to guide dosing in these situations.

Chronic kidney disease (CKD) is a significant global health challenge that impacts both patients and the health care system. This systematic review aims to evaluate the efficacy and safety of emerging therapeutic strategies for CKD management, including sodium-glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1RA), finerenone, sacubitril/valsartan, and potassium binders. We conducted searches in databases including PubMed, Scopus, CINAHL Complete, and Web of Science Core Collection to identify experimental and observational studies pertaining to each of these agents. Included studies were those that enrolled adult patients with CKD who evaluated SGLT2i, GLP-1RA, finerenone, sacubitril/valsartan, and potassium binders compared to other medications or placebo and evaluated renal-related outcomes as a primary or secondary outcome. Methodological quality and risk of bias were assessed using the Cochrane Risk of Bias (version 2) tool for experimental studies and ROBINS-I for observational studies. After screening 2135 unique studies, 138 studies were eligible for this review. These studies describe a substantial and growing body of evidence focused on improving the management of CKD beyond renin-angiotensin system inhibitors (RASi), such as angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs). Currently, SGLT2i have demonstrated consistent benefits with large effect sizes in preventing the progression of CKD, solidifying this class as a first-line treatment along with RASi. Subsequent consideration for GLP-1RA, finerenone, and sacubitril/valsartan should be dependent on patient-specific comorbidities, while potassium binders may allow for longer use of RASi.

The primary objective of this study was to determine if there was a significant change in potassium levels with sodium-glucose co-transporter-2 (SGLT2) inhibitor therapy in people with type 2 diabetes (T2D). A co-primary objective was to evaluate which factors may predispose a patient to changes in potassium levels.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are breakthrough medicines for obesity treatment and have rapidly gained widespread clinical application. Although GLP-1RAs are generally not associated with drug-drug interactions (DDIs) via drug metabolism or transporter pathways, their effects on reduced gastrointestinal (GI) motility could influence the pharmacokinetics of coadministered oral medications.

Infections caused by extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E) are increasing in the United States. Although many risk factor scoring tools exist, many are specific to bloodstream isolates and may not represent all patient populations. The purpose of this study was to create and validate an institution-specific scoring tool for select ESBL-E of non-urinary origin based on previously identified risk factors.

Recent guidelines for acute ischemic stroke (AIS) indicate administration of intravenous thrombolysis (IVT) in patients receiving direct oral anticoagulants (DOAC) is not firmly established and may be harmful unless certain potential parameters are met. This systematic review and meta-analysis explores safety outcomes and other clinical parameters from the growing number of publications describing patients taking a DOAC who experience an AIS that is treated acutely with IVT alone. Embase, International Pharmaceutical Abstracts, and PubMed were searched up to January 9, 2024 for studies including adult patients taking a DOAC who experienced an AIS treated with IVT and did not undergo endovascular therapy (EVT), regardless of the use of an anticoagulation reversal agent. Primary safety outcomes evaluated included symptomatic intracranial hemorrhage (sICH), any intracranial hemorrhage, and in-hospital mortality. A total of 873 patients from 78 studies, primarily case reports or case series of patients receiving dabigatran with or without idarucizumab reversal (n = 340), were included in the review. The rate of sICH during the index hospitalization was 3.3%. Seven high-quality studies with low risk of bias included outcomes for patients on DOAC and comparator groups of either patients not taking an oral anticoagulant (no OAC) or patients taking a vitamin K antagonist (VKA) with INR primarily <1.7 at the time of AIS. No significant difference was observed in the incidence of sICH among patients receiving DOAC vs. no OAC (odds ratio [OR] 0.8, 95% confidence interval [CI]: 0.48-1.33) or among patients receiving DOAC vs. VKA (OR 1.02, 95% CI 0.59-1.75). Similar findings of no difference were observed for other safety outcomes. Findings from this study suggest that utilization of IVT as sole recanalization therapy for AIS may be safe in patients taking a DOAC; however, further studies are needed to elucidate specific parameters that differentiate timepoints and variables to ensure safe, optimal treatment.
