Vitamin D Level Testing in an Urban Midwest Clinic: To Test or Not to Test?

Vitamin D deficiency (VDD) is significantly higher among urban populations in the U.S. Midwest, with African Americans being disproportionately affected. There is ongoing debate surrounding who and how often individuals should be screened for VDD. This study aimed to understand the prevalence of VDD, associated risk factors, and discrepancies in testing at an urban-based internal medicine residency clinic. Data were retrospectively collected on all adult patients seen by the clinic during 2018 and descriptive statistical analysis performed. Among 3976 total patients (mean age: 53 years), 18% (n=698) had vitamin D levels analyzed, with deficiency found in 71% of those tested. Mean age of the tested cohort was 59 years, and women (68%) and African Americans (72%) were found more likely to be tested. Women and patients with certain medical conditions were more likely to be tested (P<0.02 for all) but were not more likely to have VDD. Individuals with a diagnosis of chronic kidney disease were less likely to have VDD (P=0.002). Vitamin D levels typically showed improvement after retesting. A low testing rate could contribute to missed diagnoses. Overall, this study revealed that differences in rate of testing do not necessarily correlate to patients' demographical risk of VDD. Clinicians may benefit from a standardized vitamin D testing protocol.

The Use of Intracranial Vessel Wall Magnetic Resonance Imaging to Detect a Presumptive Syphilitic Brain Aneurysm.

ABSTRACT: Syphilitic intracranial aneurysm is a rare presentation of meningovascular syphilis in developed countries. In this case report, we discuss the utilization of the intracranial vessel wall magnetic resonance imaging in the management of a patient with a rare fusiform brain aneurysm, positive syphilis serologies, and inconclusive cerebrospinal fluid findings.

Jamestown Canyon virus encephalitis in a heart transplant patient.

Jamestown Canyon virus (JtCV) is an arbovirus and a member of the California serogroup. To our knowledge, all the cases of JtCV have been reported in immunocompetent patients since it was first detected in 1997. We report a case of JtCV encephalitis in a solid organ transplant patient. A 48-year-old woman from Wisconsin had multiple hospital admissions for symptoms of progressive confusion, visual hallucinations, and inability to perform self-care. Initial evaluation was significant for lymphocytes in cerebrospinal fluid (CSF), and multiple infectious and metabolic causes were excluded. Further investigation found JtCV IgM in serum, and CSF. The patient's clinical course was compatible with JtCV encephalitis, and she was treated with ribavirin in addition to reduction of her immunosuppressive medications. She showed gradual and significant improvement in her mental and functional status. JtCV can cause a variety of symptoms that range from a flu-like syndrome to encephalitis. There have been an increased number of reported cases in recent years which is attributed to increased physician awareness and the availability of laboratory testing. Optimal treatment is still not known.

Models for Predicting Incident Delirium in Hospitalized Older Adults: A Systematic Review.

PURPOSE: The purpose of this systematic review is to summarize the reported risk prediction models and identify the most prevalent factors for incident delirium in older inpatient populations (age ≥ 65 years). In the future, these risk factors could be used to develop a delirium risk prediction model in the electronic health record that can be used by the Hospital Elder Life Program to reduce the incidence of delirium. METHODS: A medical librarian customized and conducted a search strategy for all published articles on delirium prediction models using an array of electronic databases and specific inclusion and exclusion criteria. Then, a geriatrician and two research associates assessed the quality of the selected studies using the Newcastle-Ottawa Scale (NOS). RESULTS: A total of 4,351 articles were identified from initial literature search. After review, data were extracted from 12 studies. The quality of these studies was assessed using NOS and ranged from 4 to 8. The most common risk factors reported were dementia, decreased functional status, high blood urea nitrogen-to-creatinine ratio, infection and severe illness. CONCLUSIONS: The most prevalent factors associated with incidence of delirium in hospitalized older patients identified by this systematic review could be used to develop an electronic health record-generated risk prediction model to identify inpatients at risk of developing delirium.

Recurring Vivid Dreams in an Older Hmong Man With Complex Trauma Experience and Cognitive Impairment.

INTRODUCTION: Health care workers need to consider the culture and ethnic preferences prevalent in the Hmong community in order to provide optimal care. We describe an older Hmong man to illustrate the challenges faced and competencies needed by primary care. CASE PRESENTATION: An 80-year-old non-English speaking Hmong man with diabetes, nerve sheath tumor, and hypertension presented to the outpatient clinic with his grandson complaining of sleep problems. He had had 2 vivid recurring dreams during the previous few months. Memory assessment was significant for dementia. DISCUSSION: This case addresses the complexity in taking care of a non-English speaking Hmong older man who has memory loss, trauma in adulthood, multiple caregivers, and sleep problems. CONCLUSIONS: A careful history from patient and family to get to know their cultural preferences and attitudes was helpful. Identification of the primary caregiver was critical in providing care.
