About

Justine Maisha Davis is an assistant professor jointly appointed in the Department of Afroamerican and African Studies (DAAS) and the Department of Political Science at the University of Michigan. She holds a PhD from the University of California, Berkeley, and has completed postdoctoral fellowships at the University of Michigan and the University of California, San Diego, where she was a UC presidential postdoctoral fellow. Her educational background also includes a master's degree from the American University of Paris and la Sorbonne-Paris I. Her research interests include electoral violence, civil society, and the challenges to democratization efforts in post-conflict settings and weakly institutionalized democracies. Her dissertation, titled “Wartime Experiences of Civic Leaders: Legacies of Civil War, Rebel Control, and Democratization in Post-Conflict Africa,” received the Western Political Science Association best dissertation award in 2020. She has also been recognized with the Ralph Bunche Best Graduate Student Paper Award in 2018 from the African Politics Conference Group. Her scholarly work has been published or is forthcoming in several academic journals including African Affairs, Comparative Political Studies, Journal of Politics, Party Politics, PS: Political Science & Politics, and the South African Geographical Journal.

• Multiple Cardiac Arrhythmias in a Previously Healthy Child

  Pediatric Emergency Care · 2006-06-01 · 11 citations

  article1st authorCorresponding

  We present a case of multiple arrhythmias in a 3-year-old child who was presented to the emergency department with emesis. Initial vital signs were significant for a heart rate from 40 to 60 beats per minute with stable blood pressure. An electrocardiogram showed complete atrioventricular block with a junctional escape rhythm of 40 to 55 bpm that subsequently progressed to atrial flutter/fibrillation and then to a junctional escape rhythm. She was given intravenous atropine, resulting in acceleration of the junctional rhythm. Sinus rhythm resumed with a prolonged PR interval a few hours later with normalization of the electrocardiogram the following day. Routine laboratory tests, toxicology screens, and tests for other cardiac medications in the home were negative. However, at 20 hours after presentation, her digoxin level was 2.9 ng/mL. Parents denied that the child had access to any digoxin-containing substances. This case illustrates that digoxin toxicity can manifest with multiple arrhythmias and that recognition of this can be very difficult, especially when there is no witness to ingestion. Clinicians should be suspicious for digoxin toxicity when a child presents with persistent emesis, altered level of consciousness, and bradyarrhythmias with or without hemodynamic instability.

• Pregnancy and birth rates among HIV-infected women in the United States: the confounding effects of illicit drug use

  article

  OBJECTIVE: To determine the effect of HIV infection on pregnancy and birth rates and assess the potentially confounding effect of illicit drug use. DESIGN: A retrospective record review of matched cohorts examining pregnancy outcomes for HIV-positive women and two HIV-negative comparison groups (one matched by drug use). METHODS: Ninety HIV-positive women who gave birth in a US city between 1989 and 1993 were matched to HIV-negative women by race, age, parity and date of index birth (group 1, N = 180) and also by the type of illicit drug used (group 2, N = 90). Data were abstracted on tubal ligations and pregnancies occurring before April 1996. RESULTS: A total of 63% of HIV-positive women used cocaine during the index pregnancy and 26% also used opiates. HIV-positive women had fewer tubal ligations than group 1 (38.9% versus 51.1%, P = 0.058), but there was no difference when matching included drug use (38.9% in group 2). HIV infection was associated with a decrease in the number of pregnancies; this decrease was most marked when matching included drug use (18.0 versus 32.1 pregnancies per 100 woman-years,P < 0.01). There were no significant differences in spontaneous or therapeutic terminations. Poisson regression analysis demonstrated that HIV infection and older age were associated with fewer pregnancies, and cocaine use with an increased pregnancy rate. CONCLUSION: This study confirms that HIV infection is associated with a decrease in the number of pregnancies, but also illustrates the confounding effects of illicit drug use among women in the United States.

• Cytosolic-free calcium increases to greater than 100 micromolar in ATP-depleted proximal tubules.

  Journal of Clinical Investigation · 1997-08-01 · 50 citations

  articleOpen access

  Previous studies have shown that cytosolic-free Ca2+ (Caf) increases to at least low micromolar concentrations during ATP depletion of isolated kidney proximal tubules. However, peak levels could not be determined precisely with the Ca2+-sensitive fluorophore, fura-2, because of its high affinity for Ca2+. Now, we have used two low affinity Ca2+ fluorophores, mag-fura-2 (furaptra) and fura-2FF, to quantitate the full magnitude of Caf increase. Between 30 and 60 min after treatment with antimycin to deplete ATP in the presence of glycine to prevent lytic plasma membrane damage, Caf measured with mag-fura-2 exceeded 10 microM in 91% of tubules studied and 68% had increases to greater than 100 microM. Caf increases of similar magnitude that were dependent on influx of medium Ca2+ were also seen using the new low Ca2+ affinity, Mg2+-insensitive, fluorophore fura-2FF in tubules depleted of ATP by hypoxia, and these increases were reversed by reoxygenation. Total cell Ca2+ levels in antimycin-treated or hypoxic tubules did not change, suggesting that mitochondria were not buffering the increased Caf during ATP depletion. Considered in the context of the high degree of structural preservation of glycine-treated tubule cells during ATP depletion and the commonly assumed Ca2+ requirements for phospholipid hydrolysis, actin disassembly, and Ca2+-mediated structural damage, the remarkable elevations of Caf demonstrated here suggest an unexpected resistance to the deleterious effects of increased Caf during energy deprivation in the presence of glycine.
