Article Synopsis
  • The underutilization of guideline-directed medical therapy for heart failure with reduced ejection fraction among American Indian patients is linked to limited access to cardiology care, particularly in the Navajo Nation.
  • The study aimed to evaluate whether a telehealth model could enhance the use of guideline-directed medical therapy by initiating and adjusting treatment over the phone while using remote monitoring tools.
  • The Hózhó randomized clinical trial involved 103 patients and sought to measure the increase in the number of prescribed drug classes within 30 days after randomization, revealing important insights into the effectiveness of telehealth in improving heart failure management.

Article Synopsis
  • * A study analyzed Medicare data from 2015 to 2019 to evaluate the incidence, prevalence, and mortality of various heart conditions among American Indian and Alaska Native patients aged 65 and older.
  • * Among the 220,598 participants, high rates of diabetes (44.8%), hyperlipidemia (61.3%), and hypertension (72.2%) were found, with evidence of worsening heart health indicators, such as an increase in myocardial infarction rates and consistent prevalence of coronary artery disease over the study period.

Objectives: To evaluate the role of primary care healthcare delivery on survival for American Indian patients with diabetes in the southwest United States.

Methods: Data from patients with diabetes admitted to Gallup Indian Medical Center between 2009 and 2016 were analyzed using a log-rank test and Cox Proportional Hazards analyses.

Results: Of the 2661 patients included in analysis, 286 patients died during the study period.

Objective: Recent guidelines recommend a physiologic approach to non-intensive care unit (ICU) inpatient glucose management utilizing basal-bolus with correctional (BBC) insulin over traditional sliding-scale insulin monotherapy. Unfortunately, few studies exist using a BBC approach restricted to human insulins (regular and neutral protamine Hagedorn [NPH]). This study evaluated changes in provider prescribing patterns, effects on blood glucose, and safety with implementation of hospital order sets for BBC using human insulins.

We examined the effects of development, exogenous, and endogenous glucocorticoids on Na(+),K(+)-ATPase activity and subunit protein expression in ovine cerebral cortices and renal cortices. Ewes at 60%, 80%, and 90% gestation, newborns, and adults received 4 dexamethasone or placebo injections. Cerebral cortex Na(+),K(+)-ATPase activity was higher (P < .

Larval-stage summer flounder (Paralichthys dentatus) were immersed in the corticosteroid-receptor blocker RU486 to test the effects of cortisol deficiency on salinity tolerance. Premetamorphic larvae held at 10 (near isosmotic) or 30 (hyperosmotic) parts per thousand ( per thousand) seawater survived well over 5d in 0, 0.012, or 0.

Na(+)/K(+)-ATPase is a membrane-bound enzyme responsible for Na(+)/K(+) translocation across cell membranes. It is essential for the generation of electrochemical gradients, which control the ionic environment necessary for electrical activity and water and electrolyte balance. Newborn infants who are at risk of developing bronchopulmonary dysplasia (BPD) are frequently treated with corticosteroids.

These studies aim to investigate subcellular distribution of angiotensin II (ANG II) in rat luteal cells, identify other bioactive angiotensin peptides, and investigate a role for angiotensin peptides in luteal steroidogenesis. Confocal microscopy showed ANG II distributed within the cytoplasm and nuclei of luteal cells. HPLC analysis showed peaks that eluted with the same retention times as ANG-(1-7), ANG II, and ANG III.
