  • Encounter Frequency and serum glucose level blood pressure and cholesterol level control in patients with diabetes mellitus
    JAMA Internal Medicine, 2011
    Co-Authors: Fritha Morrison, Maria Shubina, Alexander Turchin
    Abstract:

    Background: More frequent patient-provider Encounters may lead to faster control of hemoglobin A1c level, blood pressure (BP), and low-density lipoprotein (LDL) cholesterol (LDL-C) level (hereafter referred to as hemoglobin A1c, BP, and LDL-C) and improve outcomes, but no guidelines exist for how frequently patients with diabetes mellitus (DM) should be seen.

  • Encounter Frequency and blood pressure in hypertensive patients with diabetes mellitus
    Hypertension, 2010
    Co-Authors: Alexander Turchin, Saveli Goldberg, Maria Shubina, Jonathan S Einbinder, Paul R Conlin
    Abstract:

    The relationship between Encounter Frequency (average number of provider-patient Encounters over a period of time) and blood pressure for hypertensive patients is unknown. We tested the hypothesis that shorter Encounter intervals are associated with faster blood pressure normalization. We performed a retrospective cohort study of 5042 hypertensive patients with diabetes mellitus treated at primary care practices affiliated with 2 academic hospitals between 2000 and 2005. Distinct periods of continuously elevated blood pressure (≥130/85 mm Hg) were studied. We evaluated the association of the average Encounter interval with time to blood pressure normalization and rate of blood pressure decrease. Blood pressure of the patients with the average interval between Encounters ≤1 month normalized after a median of 1.5 months at the rate of 28.7 mm Hg/month compared with 12.2 months at 2.6 mm Hg/month for the Encounter interval >1 month ( P P P

  • 2013. Influence of alternate reproductive tactics and pre- and postcopulatory sexual selection on paternity and offspring performance in a lizard. Behav. Ecol. Sociobiol
    2020
    Co-Authors: Scott J Keogh, Kate D L Umbers, Eleanor Wilson, Jessica Stapley, Martin J Whiting
    Abstract:

    Abstract Sexual selection theory predicts different optima for multiple mating in males and females. We used mating experiments and genetic paternity testing to disentangle preand postcopulatory mechanisms of sexual selection and alternate reproductive tactics in the highly promiscuous lizard Eulamprus heatwolei. Both sexes mated multiply: 30-60 % of clutches were sired by two to four fathers, depending on the experiment. Larger males sired more offspring when we allowed male contest competition: 52 % of large males but only 14 % of small males sired at least one offspring. In the absence of male contest competition, females mated promiscuously and there was no large male advantage: 80 % of large males and 90 % of small males sired at least one offspring, and there was no evidence for last-male precedence. Multiple mating did not yield obvious direct or indirect benefits to females. E. heatwolei represents a complex system in which males attempt to improve their fertility success by limiting rivals from access to females and through adopting alternate reproductive tactics. Conversely, females exhibit no obvious precopulatory mate choice but may influence fitness through postcopulatory means by either promoting sperm competition or through cryptic female choice. Our results support the hypothesis that female multiple mating in nonavian reptiles is best explained by the combined effect of mate Encounter Frequency and high benefits to males but low costs to females
