School of Medicine Faculty Publications

Recently, it has been suggested that central and peripheral toxicities identified in persons with substance use disorder (SUD) could be partially associated with an imbalance in reactive oxygen species and antioxidant defenses. We conducted a systematic review and meta-analysis to investigate whether SUD is associated with oxidative stress and to identify biomarkers possibly more affected by this condition. We have included studies that analysed oxidant and antioxidant markers in individuals with SUD caused by stimulants, alcohol, nicotine, opioids, and others (cannabis, inhalants, and polysubstance use). Our analysis showed that persons with SUD show higher oxidant markers and lower antioxidant markers …

Gating Intermediates Reveal Inhibitory Role Of The Voltage Sensor In A Cyclic Nucleotide-Modulated Ion Channel, Xiaolong Gao, Philipp A M Schmidpeter, Vladimir Berka, Ryan J Durham, Chen Fan, Vasanthi Jayaraman, Crina M Nimigean

Faculty, Staff and Student Publications

Understanding how ion channels gate is important for elucidating their physiological roles and targeting them in pathophysiological states. Here, we used SthK, a cyclic nucleotide-modulated channel from Spirochaeta thermophila, to define a ligand-gating trajectory that includes multiple on-pathway intermediates. cAMP is a poor partial agonist for SthK and depolarization increases SthK activity. Tuning the energy landscape by gain-of-function mutations in the voltage sensor domain (VSD) allowed us to capture multiple intermediates along the ligand-activation pathway, highlighting the allosteric linkage between VSD, cyclic nucleotide-binding (CNBD) and pore domains. Small, lateral displacements of the VSD S4 segment were necessary to open the …

Early And Progressive Mobility: A Program Implementation Strategy For High Acuity Patient Care Locations, Stefani Poland

Student Scholarly Projects

Despite an increase in the promotion of early progressive mobility, its decrease in hospital-acquired complications and improvement of patient outcomes, there remains a reluctance in staff commitment to daily evaluation and implementation. This is largely due to the fact nurses or other interprofessional staff are the primary individuals responsible for this change in process. A lack of confidence in staff to correctly identify patients that meet criteria and anxiety regarding the safe transfer or mobilization of patients, particularly in high acuity settings have been identified as major barriers. The PICOT question that guided this program development of a CBO toolkit …

Future Perspectives In Acute Myocarditis Complicated By Cardiogenic Shock, Giovanni A. Tavecchia, Iside Cartella, Enrico Ammirati

Journal of Shock and Hemodynamics

Acute myocarditis is an inflammatory disease of the myocardium with a highly variable clinical course. Fulminant myocarditis (FM) represents the most threatening scenario with hemodynamic compromise and cardiogenic shock at presentation. Despite medical advances and the availability of promising mechanical circulatory support (MCS), FM is burdened by a dismal prognosis. Early referral to tertiary hospitals with MCS facilities and prompt diagnosis with endomyocardial biopsy are critical steps toward optimal management. Moreover, beyond supportive care, the prevention of irreversible myocardial damage with immunomodulating therapies must be proven in clinical trials. In this editorial, we briefly describe current evidence and future perspectives …

Surviving Sepsis Campaign: Strategies To Implement In Cardiogenic Shock Management, James Burke Md

Journal of Shock and Hemodynamics

The Surviving Sepsis Guidelines can serve as a structure to help educate and create a set of recommendations on how to care for patients through this complicated pathway of shock. Designing a cardiogenic shock bundle could reduce the variability of care and possibly improve survival. Also, a more standard protocol would allow a review of the outcomes and a system to change practice nationally when new data or technology becomes available. This could create a continuous quality improvement cycle. Creating a “Surviving Cardiogenic Shock” system could help provide awareness for recognition of cardiogenic shock and advanced management alternatives needed at …

Role Of Invasive Hemodynamics In Shock Management: Is A Pulmonary Artery Catheter Always Necessary?, Ajay J. Kirtane

Journal of Shock and Hemodynamics

The pulmonary artery (PA) catheter can be a useful tool in the management of patients with cardiogenic shock; however, there are challenges with the use of this catheter, and clinicians must balance the risks and benefits. In addition, clinicians must properly interpret data generated from a PA catheter in the context of other data to optimize a patient's hemodynamics.

There are long-standing concerns that people experiencing homelessness may not recover well if left unsupported after a hospital stay. This study reports on a study investigating the cost-effectiveness of three different 'in patient care coordination and discharge planning' configurations for adults experiencing homelessness who are discharged from hospitals in England. The first configuration provided a clinical and housing in-reach service during acute care and discharge coordination but with no 'step-down' care. The second configuration provided clinical and housing in-reach, discharge coordination and 'step-down' intermediate care. The third configuration consisted of housing support workers providing in-reach and discharge coordination as well …

Hip Osteoarthritis: A Novel Network Analysis Of Subchondral Trabecular Bone Structures, Mohsen Dorraki, Dzenita Muratovic, Anahita Fouladzadeh, Johan W Verjans, Andrew Allison, David M Findlay, Derek Abbott

Faculty, Staff and Student Publications

Hip osteoarthritis (HOA) is a degenerative joint disease that leads to the progressive destruction of subchondral bone and cartilage at the hip joint. Development of effective treatments for HOA remains an open problem, primarily due to the lack of knowledge of its pathogenesis and a typically late-stage diagnosis. We describe a novel network analysis methodology for microcomputed tomography (micro-CT) images of human trabecular bone. We explored differences between the trabecular bone microstructure of femoral heads with and without HOA. Large-scale automated extraction of the network formed by trabecular bone revealed significant network properties not previously reported for bone. Profound differences …

Fight-or-flight responses involve β-adrenergic-induced increases in heart rate and contractile force. In the present study, we uncover the primary mechanism underlying the heart's innate contractile reserve. We show that four protein kinase A (PKA)-phosphorylated residues in Rad, a calcium channel inhibitor, are crucial for controlling basal calcium current and essential for β-adrenergic augmentation of calcium influx in cardiomyocytes. Even with intact PKA signaling to other proteins modulating calcium handling, preventing adrenergic activation of calcium channels in Rad-phosphosite-mutant mice (4SA-Rad) has profound physiological effects: reduced heart rate with increased pauses, reduced basal contractility, near-complete attenuation of β-adrenergic contractile response and diminished …

A Methodological And Clinical Approach To Measured Energy Expenditure In The Critically Ill Pediatric Patient., Jaime Silva-Gburek, Paola Hong Zhu, Marwa Mansour, David Walding, Jorge A. Coss-Bu

Manuscripts, Articles, Book Chapters and Other Papers

The metabolic response to injury and stress is characterized initially by a decreased energy expenditure (Ebb phase) followed by an increased metabolic expenditure (Flow phase). Indirect calorimetry is a methodology utilized to measure energy expenditure and substrate utilization by measuring gas exchange in exhaled air and urinary nitrogen. The use of indirect calorimetry in critically ill patients requires precise equipment to obtain accurate measurements. The most recent guidelines suggested that measured energy expenditure by indirect calorimetry be used to determine energy requirements. This article reviews the methodological and clinical use of indirect calorimetry in critically ill pediatric patients.
