Urinary tract infection (UTI) is a common reason for emergency department (ED) utilization that could potentially be treated by a primary care provider (PCP). This study assessed patient perceived value of a home UTI test kit plus educational materials and its impact on ED utilization for a UTI symptom episode. Women aged 18-75 years with Medicaid insurance and a history of 1-3 uncomplicated UTIs in the past year were prospectively identified and randomized to the intervention, intervention plus (intervention plus a patient portal message before its delivery), or standard of care group.

Many older adults experience a deterioration in cognitive function with aging, and this can have a negative impact on quality of life. Late-life depression has been linked to mild cognitive impairment and dementia, and treating depression with an agent that has procognitive effects could be beneficial. Vortioxetine is a novel antidepressant with a multimodal mechanism of action that works primarily serotonin transporter inhibition, 5-HT receptor agonism and 5-HT receptor antagonism.

Angioedema is a serious adverse event that can manifest as lower extremity edema, face swelling, rash, hives, and a swollen tongue, which can sometimes lead to airway constriction and death. It is a well-documented reaction within the angiotensin-converting enzyme inhibitor drug class, where the bradykinin pathway leads to angioedema. We report a case where a patient experienced angioedema after taking venlafaxine.

Studies have reported changes in the endocannabinoid system in the brain of patients with Alzheimer's disease (AD), playing a role in the pathophysiology of AD. Cannabinoids have been shown to have neuroprotective properties, reduce neuroinflammation, and enhance neurogenesis. Evidence suggests that the utilization of marijuana products containing both tetrahydrocannabinol (THC) and cannabidiol (CBD) or CBD alone have been effective and safe for use in older people with agitation associated with dementia.

Antidepressants are widely used medications for a range of medical conditions such as mood disorders and chronic pain in older adults. A vast body of evidence exists concerning the risks of QT interval prolongation associated with these agents and healthcare providers should critically evaluate the potential for QT prolongation when selecting antidepressant agents. Long QT syndrome is a disorder of myocardial repolarization that manifests as a prolonged QT interval on an electrocardiogram (ECG) and has been demonstrated to increase with age.

An increased risk of bacterial resistance toward fluoroquinolones and the increased risk of disabling and serious adverse effects prompted the US Food and Drug Administration to recommend limiting fluoroquinolone use to the treatment of community-acquired pneumonia, skin and skin-structure infections, bacterial sinusitis, plague, chronic bronchitis exacerbations, and complicated intra-abdominal infections. We report a case of moxifloxacin-induced tinnitus in an older adult prescribed oral moxifloxacin 400 mg for 5 days for the treatment of acute diverticulitis, due to allergies to nonfluoroquinolone preferred agents. A thorough literature review provided few other reported incidents of this rare and serious adverse event.

Proton-pump inhibitors (PPIs) are a widely prescribed class of medications used to treat acid-related disorders and use has significantly increased over the last few decades. PPIs are often inappropriately prescribed and since they have been on the market, a number of post-marketing studies have been published demonstrating associations between longer duration of PPI therapy and a number of adverse effects that are a concern in older adults. The objective of this review is to discuss the existing literature of potential adverse effects with long-term PPI use in older adults and to summarize the implications in clinical practice.
