Faculty, Staff and Students Publications

Background: Tuberculosis (TB) treatment monitoring is hindered by the lack of a rapidly measured biomarker that accurately predicts clinically relevant outcomes. Symptom screening poorly correlates with bacillary burden. Although culture is a direct measure of viable bacillary burden, the long turnaround time makes it clinically irrelevant.

Methods: The TB treatment monitoring potential of stool-based, quantitative polymerase chain reaction (qPCR) was prospectively assessed among 231 participants of all ages from Eswatini, Tanzania, and Mozambique with microbiologically confirmed TB. Stool qPCR results were compared to sputum culture, persistent symptoms, drug resistance, and World Health Organization TB outcomes.

Results: Quantitative bacillary burden measured …

Low-Dose Metformin Requires Brain Rap1 For Its Antidiabetic Action, Hsiao-Yun Lin, Weisheng Lu, Yanlin He, Yukiko Fu, Kentaro Kaneko, Peimeng Huang, Ana B De La Puente-Gomez, Chunmei Wang, Yongjie Yang, Feng Li, Yong Xu, Makoto Fukuda

Faculty, Staff and Students Publications

Metformin is the most commonly prescribed antidiabetes drug, yet its precise mechanism of action remains controversial. Previous studies have suggested that metformin acts peripherally by reducing hepatic glucose output and altering gut functions. Here, we report a neural mechanism via the small guanosine triphosphatase Ras-related protein 1 (Rap1). Mice with forebrain-specific Rap1 knockout exhibited resistance to the antidiabetic effects of low-dose metformin while remaining sensitive to other antidiabetic agents. Centrally administered metformin inhibited brain Rap1 and reduced hyperglycemia. Conversely, forced activation of brain Rap1 increased glycemia and abolished the glycemic effect of metformin. Metformin activated a specific subset of neurons …

Nerve-To-Cancer Transfer Of Mitochondria During Cancer Metastasis, Gregory Hoover, Shila Gilbert, Olivia Curley, Clémence Obellianne, Mike T Lin, William Hixson, Terry W Pierce, Joel F Andrews, Mikhail F Alexeyev, Yi Ding, Ping Bu, Fariba Behbod, Daniel Medina, Jeffrey T Chang, Gustavo Ayala, Simon Grelet

The nervous system has a pivotal role in cancer biology, and pathological investigations have linked intratumoural nerve density to metastasis1. However, the precise impact of cancer-associated neurons and the communication channels at the nerve–cancer interface remain poorly understood. Previous cancer denervation models in rodents and humans have highlighted robust cancer dependency on nerves, but the underlying mechanisms that drive nerve-mediated cancer aggressivity remain unknown2,3. Here we show that cancer-associated neurons enhance cancer metabolic plasticity by transferring mitochondria to cancer cells. Breast cancer denervation and nerve–cancer coculture models confirmed that neurons significantly improve tumour energetics. …

Genomic resources, such as draft genomes, are vital for biodiversity monitoring and conservation. For endangered species, they enable the development of tools like organellar genomes and molecular markers, which are crucial for population genetics. Advances in sequencing technologies now allow high‐throughput genotyping with detailed amplicon sequences, enhancing genetic variation studies. The northern muriqui ( Brachyteles hypoxanthus ), a critically endangered primate endemic to Brazil's Atlantic Forest, currently lacks both nuclear and mitochondrial genome data and species‐specific microsatellite markers for population genetic studies. We assembled a 2.52 Gb draft genome for B. hypoxanthus with 202,243 contigs (N50 = 29,134 bp), and …

Changes In Post-Transplant Serum Testosterone Levels In Men Undergoing Lung Transplantation: A Pilot Study Using The Trinetx Research Network, Austin Thompson, Danly Omil-Lima, Jaime Abraham Perez, Erin Jesse, Mohit Khera, Kenneth Chavin, Nannan Thirumavalavan

Faculty, Staff and Students Publications

Hypogonadism is understudied in men requiring solid organ transplants, particularly among lung transplant recipients. Improvement in serum testosterone levels has been reported in kidney and liver transplantation. Using the TriNetX Research Network, we performed a retrospective cohort study to evaluate the incidence of peri-transplant hypogonadism and the natural course of serum testosterone following successful lung transplantation. Men aged ≥ 18 with a lung transplant and total testosterone drawn within one year pre- and post-transplant were included. Men with receipt of testosterone therapy were excluded. A low testosterone (< 300 ng/dL) and normal testosterone (≥300 ng/dL) cohort was created before employing descriptive and analytic statistics to investigate the incidence of peri-transplant hypogonadism and the change in serum testosterone levels following lung transplantation. In our entire cohort, lung transplantation was not associated with a significant increase in post-transplant serum testosterone (329.86 ± 162.56 ng/dL pre-transplant and 355.13 ± 216.11 ng/dL post-transplant, p = 0.483). The number of men with low testosterone decreased by 9.8% following lung transplantation but was not significant, p = 0.404. In this pilot study, no significant change in the number of hypogonadal men nor serum testosterone levels was observed among men undergoing lung transplantation.

Nephrostomy (Pcn) Versus Nephroureteral Stent (Double Jj); An Ongoing Battle, Mohammad Ghasemi-Rad, Kelly Trinh, David Wynne, Mohadese Ahmadzade, Muhammad Hamza Shamim, Omar Guerrero, Ashley Bancroft, Shreya Ranganath, David Leon

Faculty, Staff and Students Publications

In the realm of medical procedures for urinary obstructions, a distinct division of roles is evident: the vast majority of percutaneous nephrostomies (PCNs) are the domain of Interventional Radiology (IR), while the placement of double J stents (JJ stents) falls squarely under Urology. This division, however, is not without its complexities. When confronted with a patient suffering from a urinary obstruction, the decision-making process can become intricate. The underlying cause often fuels the debate: should IR intervene with a PCN, or should Urology place a JJ stent? Such decisions have profound implications for the individual patient.In this comprehensive review, we …

Mechanisms Underlying Atrial Fibrillation In Chronic Kidney Disease, Jose Alberto Navarro-Garcia, Joshua A Keefe, Jia Song, Na Li, Xander H T Wehrens

Chronic kidney disease (CKD) is a serious and progressive worldwide health problem affecting 15 % of the global population. CKD is associated with higher mortality rates due to secondary complications such as cardiovascular disease. Common cardiovascular complications found in CKD patients include left ventricular hypertrophy, heart failure, and cardiac arrhythmias. The most common type of cardiac arrhythmia in CKD patients is atrial fibrillation (AF). Proper management of AF is important due to its high risk of cardiovascular complications and stroke. The incidence of AF remains higher in CKD patients than in the healthy population, highlighting the need to improve our …

Community-Engaged Medical Student Elective To Improve Knowledge And Attitudes Toward Individuals With Intellectual And Developmental Disabilities, Kathryn J Kemere, Nital Appelbaum, Priya Chandan, Elisha Acosta

Faculty, Staff and Students Publications

Individuals with intellectual and developmental disabilities (IDD) face multiple barriers to inclusion throughout life. One barrier is the medical knowledge and biases of adult healthcare providers with diagnoses traditionally associated with childhood. Medical school curricula have limited content related to IDD, and students have limited opportunities to engage with community organizations during their clinical years. Methods: We created a one-month clinical elective to address medical students' attitudes and knowledge regarding individuals with IDD using experiential learning. Students saw adult patients in our primary care clinic with a variety of IDD diagnoses and spent 30% of their time at community sites …

Duncan NRI Faculty and Staff Publications

Rare genetic diseases (RDs) with primary neuropsychiatric symptoms pose unique challenges for diagnosis and management. While the majority of these RDs have neuropsychiatric symptoms that are secondary to the RD, a subset presents with primary neuropsychiatric symptoms directly linked to their underlying pathophysiology. This subset has significant unmet medical need with delayed diagnoses leading to prolonged delays in treatment optimization and the trialing of medications that fail to target the underlying pathophysiology. This comprehensive review identifies 108 RDs with central neuropsychiatric symptoms that have a 7.7-year average diagnostic delay. Optimal management strategies for these RDs typically includes non-psychotropic medications, dietary …

Allergic diseases, particularly food allergy, can be associated with significant psychosocial impairment. Allergist-immunologists can provide evidence-based information to correct misperceptions and misunderstandings regarding food allergy that may perpetuate cycles of fear and anxiety. Whereas motivational interviewing can be an empathetic approach to empower patients to actualize health goals, cognitive behavioral therapy (CBT) aims to provide disease-state insight to facilitate an understanding of risk that can transform health beliefs and behaviors. Brief CBT is a clinical approach that can help address ineffective management paradigms through conversations that begin with curious questions. In this review, we discuss evidence supporting implementation of an …

Faculty, Staff and Students Publications

Cyclin dependent kinases 4 and 6 inhibitors have brought great improvements in the treatment of luminal breast cancer, but resistance is a major clinical hurdle. Multiple biomarkers of resistance have been proposed, but none is currently utilized in clinical practice. By performing single-cell RNA sequencing of seven palbociclib-naïve luminal breast cancer cell lines and palbociclib-resistant derivatives, we show that established biomarkers and pathways related to CDK4/6i resistance present marked intra- and inter- cell-line heterogeneity. Transcriptional features of resistance could be already observed in naïve cells correlating with levels of sensitivity (IC50) to palbociclib. Resistant derivatives showed transcriptional clusters that significantly …
