Background: Patients' level of medication adherence provides conflicting results in its relationship to patient activation. Multiple factors may be contributing to these mixed results.
Objectives: The primary purpose was to assess the association of patient activation to medication adherence in adults with chronic health conditions and low health literacy (HL). Secondary objectives were to determine whether age, education, gender, and race were associated with activation.
Methods: Participants completed self-report questionnaires regarding chronic disease self-management. Patient activation was measured using Hibbard's Patient Activation Measure (PAM). Self-report of medication adherence was determined using the Gonzalez-Lu adherence questionnaire. Block regressions first assessed the relation of demographic variables and education to adherence and then the added relation of patient activation in a second model.
Results: The analyses included 301 participants (mean age 58 years; 53% female; mean chronic conditions of 6.6). Some of the most common chronic conditions included hypertension (60%), arthritis (51%), depression (49%), and hyperlipidemia (43%). The relation of older age to greater medication adherence was significant (P < 0.05) in both models. The addition of PAM was significantly related to better adherence (P < 0.001) and also increased the R squared value from 0.04 to 0.09. This change resulted in a moderate effect size (d = 0.50).
Conclusion: Evaluating patient activation at baseline may predict those more likely to be medication adherent in patients with low HL.

Background: Primary care physicians (PCPs) and nurse practitioners play a key role in guiding caregivers on early peanut protein (PP) introduction, yet many lack adequate knowledge.
Aim Statement: This quality improvement study aimed to enhance understanding among PCPs and caregivers about evidence-based guidelines for early PP introduction in infants' diets.
Methods: Using the Stetler Model, PCP knowledge was evaluated through pre-test, educational video and some posttest material.
Adjunctive PCSK9 Inhibitor Evolocumab in the Prevention of Early Neurological Deterioration in Non-cardiogenic Acute Ischemic Stroke: A Multicenter, Prospective, Randomized, Open-Label, Clinical Trial.

Background: Early neurological deterioration (END) is associated with a poor prognosis in acute ischemic stroke (AIS). Effectively lowering low-density lipoprotein cholesterol (LDL-C) can improve the stability of atherosclerotic plaque and reduce post-stroke inflammation, which may be an effective means to lower the incidence of END. The objective of this study was to determine the preventive effects of evolocumab on END in patients with non-cardiogenic AIS.

Purpose: This study investigated elite German athletes to (1) assess their serum 25(OH)D levels and the prevalence of insufficiency, (2) identify key factors influencing serum 25(OH)D levels, and (3) analyze the association between serum 25(OH)D levels and handgrip strength.
Methods: In this cross-sectional study, a total of 474 athletes (231 female), aged 13-39 years (mean 19.3 years), from ten Olympic disciplines were included.
Investigating proteogenomic divergence in patient-derived xenograft models of ovarian cancer.

Within ovarian cancer research, patient-derived xenograft (PDX) models recapitulate histologic features and genomic aberrations found in original tumors. However, conflicting data from published studies have demonstrated significant transcriptional differences between PDXs and original tumors, challenging the fidelity of these models. We employed a quantitative mass spectrometry-based proteomic approach coupled with generation of patient-specific databases using RNA-seq data to investigate the proteogenomic landscape of serially-passaged PDX models established from two patients with distinct subtypes of ovarian cancer.

Background: The medico-surgical management of cardiac tumors when there is a suspicion of malignancy is complex. Moreover, in a critically ill setting, the choice of diagnostic tools seems crucial.
Case Presentation: We present the case of a sixty-four-year-old patient with no prior medical history who was admitted to the intensive care unit with obstructive shock secondary to a right heart mass and pulmonary embolism.
