As a whole, this research suggests that an integrated study of mind and body is necessary to fully understand the determinants and consequences of CVD.
The everolimus-eluting stent (EES), one of the effective stents for in-stent restenosis (ISR), has a lower incidence of stent thrombosis; however, the underlying mechanism remains unknown. This study aimed to identify the effects of everolimus on vascular metabolism and thrombogenicity and examine their mechanistic link.
EESs and bare-metal stents were implanted in rabbit iliac arteries with smooth muscle cell (SMC)-rich neointima induced by endothelial denudation. Four weeks after stent implantation, the stented arteries were examined for histological analysis and metabolomics. Additionally, everolimus effects in coronary artery SMCs metabolism, tissue factor (TF) expression, and procoagulant activity were assessed in vitro.
EES-implanted arteries showed decreased neointima formation, less SMCs infiltration, and reduced TF expression. Concomitantly, they were metabolically characterized by increased levels of metabolites in amino acids, such as glutamine. Similarly, everolimus increased intracellular glutamine levels, decreased TF expression, and reduced procoagulant activity in SMCs in vitro. On the contrary, exogenous glutamine administration also increased intracellular glutamine level, decreased TF expression, and reduced procoagulant activity despite enhanced mammalian target of rapamycin (mTOR) activity.
Intracellular glutamine level is likely to determine vascular SMC-related thrombogenicity regardless of mTOR pathway activity. Therefore, increased intracellular glutamine level might contribute partially to the beneficial effect of EES use on stent thrombosis.

Using evidence from the opioid crisis in the United States, this paper assembles and analyzes novel data on Congressional statements to explore the conditions under which politicians (1) issue public statements about opioids and (2) frame the opioid crisis as a predominantly public health or law enforcement problem. RepSox We examined 3.8 million Congressional floor speeches and 111,000 public statements to identify (1) floor speeches about drug crises in the 97th to 114th Congresses (1981-2017) and (2) public statements about the opioid crisis in the 116th Congress (2019-2020). Moderate ideology, women, greater overdose deaths, and larger white populations are associated with significantly higher frequencies of opioid statements. Using a dictionary-based text analysis approach, we find that ideologically liberal and African American legislators are more likely to use public health framing, while ideologically conservative members are more likely to use law enforcement framing and refer to national borders or foreign countries in opioid statements. Democrats/liberals more often referenced medication treatment for opioids. These findings imply two broader conclusions about the nature of political discourse in public health crises. First, that political extremists are least likely to talk about opioids suggests that increasing partisan polarization may result in less discussion, emphasis, and expertise in public health issues. Second, the tenor of discourse about opioids and other public health crises is likely to change with partisan electoral waves, potentially hindering long term planning of public health capacity.
This article presents demographic and care factors related to persons who are substance-involved and require inpatient administration of intravenous antibiotics.
This study was conducted to explore healthcare responses to support substance-involved inpatients, through exploration of documented client outcomes, healthcare provider accounts, and representation of clients through documentation.
A patient-oriented research team undertook this multiple methods, exploratory study. A health record review included people admitted to a complex continuing care hospital, within a 2-year period, for long-term antibiotic treatment and concurrent illicit substance use. Correlations were examined between whether or not clients were discharged against medical advice (AMA) in comparison to demographic, medical, and care-related factors. Qualitative analysis of narrative health record data was undertaken. Semi-structured interviews of healthcare providers and decision makers were conducted.
Twenty-five people met recruare integrated into all inpatient practice areas, iii) support effective harm reduction practices for hospital-admitted clients, and iv) develop robust policies and protocols to support healthcare providers and inpatients.
Bilateral inferior petrosal sinus sampling (BIPSS) is an important procedure in the diagnostic work-up of Cushing's syndrome (CS). In this study, we investigated the diagnostic performance of BIPSS in detecting the source of adrenocorticotropic hormone (ACTH) secretion in Cushing's disease (CD) without radiological evidence.
Thirty-five consecutive patients who underwent BIPSS due to ACTH-dependent CS between 2010 and 2019 in our clinic and subsequently underwent transsphenoidal surgery were included. The indication for BIPSS was biochemically proven ACTH-dependent CS but normal or ≤6mm pituitary lesion in pituitary magnetic resonance imaging (MRI). Corticotropin releasing hormone (CRH) stimulation was applied to all patients during the BIPSS procedure. BIPSS data, MRI results, pathological findings, and follow-up results were analyzed. The diagnostic performance of BIPSS was calculated.
A total of 35 patients, 6 (17%) males and 29 (83%) females, were included in the study. Pituitary MRI was normal in 12 (34.3%) and revealed lesions ≤6mm in 23 (65.7%) patients. BIPSS lateralized the right side in 13 (37.1%) and left side in 18 (51.4%) patients, while no lateralization was observed in the remaining 4 (11.5%) patients. BIPSS showed lateralization in the same direction with pituitary adenoma in 21 (60%) patients before CRH injection and in 29 (83%) patients after CRH injection (p=0.034). The sensitivity of the BIPSS procedure was 88%. Accurate localization of the pituitary lesion was more frequent when based on BIPSS results than on MRI (83% vs. 51%, P=0.005).
BIPSS appears to be a valuable and safe diagnostic tool in patients who are diagnosed with CD biochemically but do not have clear radiological evidence of ACTH-producing lesion.
