Clinical trials conducted in the Lonny Yarmus Lab focus primarily on minimally-invasive diagnostic testing for patients with lung cancer and local therapy options for malignant airway obstructions. We investigate ways to improve the early diagnosis of lung cancer, as well as the treatment of later-stage cancer, using the least invasive methods possible. We are also part of the LIBERATE clinical study for patients who have difficulty breathing and suffer from severe emphysema.

Research in the Leonard Feldman Lab is focused on consult medicine, high-value care and medical education, including resident training and online curriculum. Past studies include integrating lessons on respect and courtesy toward patients into the training of residents and the impact of including the cost of medical procedures when residents ordered tests.

Research in the Lee Bone Lab uses community-based participatory approaches to promote health in underserved urban African-American populations. We conduct randomized clinical trials on cardiovascular disease, diabetes and cancer detection and control in order to test the success of community interventions. We focus in particular on making interventions sustainable and on implementing electronic education to improve communication.

The Laura Hummers Lab participates in a number of clinical trials and clinical investigations at the Scleroderma Center at Johns Hopkins. We have a particular interest in the predictors of outcomes in scleroderma. We’ve established a prospective cohort of 300 scleroderma patients to identify incident vascular outcomes in the hopes of identifying new biomarkers for disease development and progression.

The Kathryn Carson Lab investigates ways to improve medical research, particularly in the areas of brain and thyroid cancer, Alzheimer’s disease, atherosclerosis, hypertension, HIV and lupus. Our team seeks to help researchers optimize their studies through better study design, protocol and grant writing, data cleaning and analysis, and publication writing. We work with investigators from a wide range of departments through the Johns Hopkins Institute for Clinical and Translational Research.

The Karakousis Lab is primarily focused on understanding the molecular basis of Mycobacterium tuberculosis persistence and antibiotic tolerance. A systems biology-based approach, including the use of several novel in vitro and animal models, in combination with transcriptional, proteomic, genetic, imaging, and computational techniques, is being used to identify host cytokine networks responsible for immunological control of M. tuberculosis growth, as well as M. tuberculosis regulatory and metabolic pathways required for bacillary growth restriction and reactivation. In particular, we are actively investigating the regulatory cascade involved in the mycobacterial stringent response. Another major focus of the lab is the development of host-directed therapies for TB, with the goal of shortening treatment and improving long-term lung function. Additional research interests include the development of novel molecular assays for the rapid diagnosis of latent TB infection and active TB disease, and for the detection of drug resistance.

Work in the Kristin Riekert Lab focuses on methods for improving health care quality and delivery, particularly among underserved and disadvantaged populations. Our research covers a range of important topics, including health beliefs, treatment adherence, doctor-patient communication, self-management interventions, mobile health initiatives, health disparities and patient-reported outcome methodology. We also work with the National Institutes of Health on multiple intervention trials focused on improving adherence and health outcomes in asthma, chronic kidney disease, cystic fibrosis (CF), sickle cell disease and secondhand smoke reduction.

Research in the Kimberly Skarupski Lab focuses on depression, geriatric medicine, psychiatry and the behavioral sciences. Recent studies have investigated various aspects of cognitive decline in biracial older adult and urban older adult community-based populations. Additional studies have investigated depression symptoms, disability and worship practices in older adults, with particular attention to racial disparities in these areas.

Basic science investigations span an array of inquiries, such as understanding the basic mechanisms underlying cardiac dyssynchrony and resynchronization in the failing heart, and beneficial influences of nitric oxide/cGMP/protein kinase G and cGMP-targeted phosphdiesterase signaling cascades on cardiac maladaptive stress remodeling. Recently, the latter has particularly focused on the role of phosphodiesterase type 5 and its pharmacologic inhibitors (e.g. sildenafi, Viagra®), on myocyte signaling cascades modulated by protein kinase G, and on the nitric oxide synthase dysregulation coupled with oxidant stress. The lab also conducts clinical research and is presently exploring new treatments for heart failure with a preserved ejection fraction, studying ventricular-arterial interaction and its role in adverse heart-vessel coupling in left heart failure and pulmonary hypertension, and testing new drug, device, and cell therapies for heart disease. A major theme has been with the use of advanced non-invasive and invasive catheterization-based methods to assess cardiac mechanics in patients.asive and invasive catheterization-based methods to assess cardiac mechanics in patients. David Kass, MD, is currently the Director at the Johns Hopkins Center for Molecular Cardiobiology and a professor in cellular and molecular medicine.

The Outcomes After Critical Illness and Surgery Group is focused on understanding and improving patient outcomes after critical illness and surgery. Research projects include improving long-term outcomes research for acute respiratory distress syndrome/acute respiratory failure (ARDS/ARF) patients; examining the long-term outcomes for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) patients; and evaluating the effects of lower tidal volume ventilation and other aspects of critical illness and ICU care on the long-term physical and mental health outcomes of ALI/ARDS patients.
