A patient-centered evaluation of a novel medical student-based patient navigation program

OBJECTIVES

Understand the patient experience of a pilot medical student-based patient navigator (PN) program. (2) Assess areas of improvement for further development as a model for expansion.

METHODS

This was a cross-sectional study assessing patients' subjective experience of medical student navigators for rheumatological conditions. Current student navigators contacted enrolled patients by phone with both structured and free-response questions.

RESULTS

44 of 71 patients completed the questionnaire. 84% reported a satisfaction of ≥ 4 on a 5 point Likert scale. > 80% of patients felt that the program helped them better care for their health, feel more understood by their medical team, and feel cared for by their healthcare team. Medical student navigators were able to assist with most patient requests.

CONCLUSIONS

Patients enrolled in our medical student PN program expressed high levels of satisfaction and felt better able to access health resources with the help of a navigator.

PRACTICE IMPLICATIONS

Employing medical students as PNs may serve as a mutually beneficial intervention providing early clinical exposure to students while furthering patient access to care. Other institutions may benefit from similarly structured interventions.

Knowledge of Pelvic Floor Dysfunction in African American and Afro-Caribbean Women Seeking Medical Care in a Primary Care Ambulatory Setting

IMPORTANCE

Approximately one fourth of U.S. community-dwelling women will develop a pelvic floor dysfunction (PFD) within their lifetimes. Prior research has revealed that knowledge of PFD was low to moderate in the general population and lower among Black patients.

OBJECTIVE

This study aimed to assess the proficiency of urinary incontinence and pelvic organ prolapse (POP) in self-identified African American and Afro-Caribbean adult (age ≥ 18 years) female patients seeking medical care in our ambulatory setting.

STUDY DESIGN

In this cross-sectional study, we administered the Prolapse and Incontinence Knowledge Questionnaire to patients in primary care and gynecology ambulatory settings at an academic medical center in Central Brooklyn. We used a multivariable Poisson regression model to find characteristics of the participants that are associated with proficiency in Prolapse and Incontinence Knowledge Questionnaire domains.

RESULTS

A total of 266 survey participants self-identified as African American or Afro-Caribbean. Overall, using a multivariable model, knowledge of POP was significantly higher among African Americans than Afro-Caribbeans, and 75.5% of our patients reported that they would seek information on urinary incontinence and POP from a medical provider (gynecologist or primary care doctor) compared with other alternatives (eg, internet, 19.6%).

CONCLUSIONS

These findings highlight subgroups that could benefit from provider-initiated education regarding PFD. Furthermore, although Black patients are often homogenized in research studies, differences may exist within subgroups likely because of varying interplays of structural racism and other social determinants of health, which may serve as an area of future research.

The pivotal role of heme Oxygenase-1 in reversing the pathophysiology and systemic complications of NAFLD

The pathogenesis and molecular pathways involved in non-alcoholic fatty liver disease (NAFLD) are reviewed, as well as what is known about mitochondrial dysfunction that leads to heart disease and the progression to steatohepatitis and hepatic fibrosis. We focused our discussion on the role of the antioxidant gene heme oxygenase-1 (HO-1) and its nuclear coactivator, peroxisome proliferator-activated receptor-gamma coactivator (PGC1-α) in the regulation of mitochondrial biogenesis and function and potential therapeutic benefit for cardiac disease, NAFLD as well as the pharmacological effect they have on the chronic inflammatory state of obesity. The result is increased mitochondrial function and the conversion of white adipocyte tissue to beige adipose tissue ("browning of white adipose tissue") that leads to an improvement in signaling pathways and overall liver function. Improved mitochondrial biogenesis and function is essential to preventing the progression of hepatic steatosis to NASH and cirrhosis as well as preventing cardiovascular complications.

Fluorination at the 4 position alters the substrate behavior of L-glutamine and L-glutamate: Implications for positron emission tomography of neoplasias

Two 4-fluoro-L-glutamine diastereoisomers [(2S,4R)-4-FGln, (2S,4S)-4-FGln] were previously developed for positron emission tomography. Label uptake into two tumor cell types was greater with [¹⁸F](2S,4R)-4-FGln than with [¹⁸F](2S,4S)-4-FGln. In the present work we investigated the enzymology of two diastereoisomers of 4-FGln, two diastereoisomers of 4-fluoroglutamate (4-FGlu) (potential metabolites of the 4-FGln diastereoisomers) and another fluoro-derivative of L-glutamine [(2S,4S)-4-(3-fluoropropyl)glutamine (FP-Gln)]. The two 4-FGlu diastereoisomers were found to be moderate-to-good substrates relative to L-glutamate of glutamate dehydrogenase, aspartate aminotransferase and alanine aminotransferase. Additionally, alanine aminotransferase was shown to catalyze an unusual γ-elimination reaction with both 4-FGlu diastereoisomers. Both 4-FGlu diastereoisomers were shown to be poor substrates, but strong inhibitors of glutamine synthetase. Both 4-FGln diastereoisomers were shown to be poor substrates compared to L-glutamine of glutamine transaminase L and α-aminoadipate aminotransferase. However, (2S,4R)-4-FGln was found to be a poor substrate of glutamine transaminase K, whereas (2S,4S)-4-FGln was shown to be an excellent substrate. By contrast, FP-Gln was found to be a poor substrate of all enzymes examined. Evidently, substitution of H in position 4 by F in L-glutamine/L-glutamate has moderate-to-profound effects on enzyme-catalyzed reactions. The present results: 1) show that 4-FGln and 4-FGlu diastereoisomers may be useful for studying active site topology of glutamate- and glutamine-utilizing enzymes; 2) provide a framework for understanding possible metabolic transformations in tumors of ¹⁸F-labeled (2S,4R)-4-FGln, (2S,4S)-4-FGln, (2S,4R)-4-FGlu or (2S,4S)-4-FGlu; and 3) show that [¹⁸F]FP-Gln is likely to be much less metabolically active in vivo than are the [¹⁸F]4-FGln diastereoisomers.
