All surgeries were performed by a single surgeon with over 20 years of surgical experience. This study employed cumulative summation test (CUSUM) analysis to quantify the learning …

Corneal Sensory Nerve Regulation Of Tear Production Through Stimulation Of Transient Receptor Potential Melastatin 8 (Trpm8) Channel: A Potential New Approach For Treating Dry Eye Disease, Juana Gallar, Stephen Pflugfelder, Anat Galor, Preeya K Gupta, Pedram Hamrah

Faculty, Staff and Students Publications

The lacrimal functional unit (LFU) tightly controls the secretion of all tear components, thus playing a critical role in maintaining ocular surface homeostasis. Forming an exquisitely sensitive neural network across the ocular surface, corneal sensory nerves detect environmental stimuli (e.g., temperature, chemicals, and mechanical pressure) through transient receptor potential (TRP) ion channels. Among these, TRP melastatin 8 (TRPM8) is a key regulator of basal tear production. Stimulated by the small temperature reductions and tear film osmolarity increases that arise due to evaporative cooling, TRPM8 activates the LFU, leading to increased basal tear production. Here, we focus on reviewing the topical …

Using Latent Patient-Centered Fear Extinction Profiles To Guide Treatment In Pediatric Ocd, Katherine M Ingram, Eric A Storch, Daniel A Geller, Brent J Small, Sabine Wilhelm, Joseph F Mcguire

Faculty, Staff and Students Publications

Background: While exposure with response prevention (ERP) is the frontline treatment for pediatric obsessive-compulsive disorder (OCD), not all patients benefit. Impairments in extinction learning are implicated in pediatric OCD's etiology and treatment, with impaired pre-treatment extinction learning associated with worse ERP outcomes. However, available methods for assessing patients' difficulties with fear extinction are costly and underdeveloped. In response, we used person-centered profiles to characterize latent fear extinction patterns among youth with OCD, and investigated the degree to which scores on common rating scales correspond to profile membership.

Methods: Youth with OCD (n=98) completed a diagnostic clinical battery followed by a …

An Online Treatment Decision Aid For Men With Low-Risk Prostate Cancer Eligible For Active Surveillance And Their Partners Increases The Uptake Of Active Surveillance: The Navigate Randomised Controlled Trial, Penelope Schofield, Stephen Quinn, Natalie Richards, Alan White, Fiona White, Mark Frydenberg, Suzanne Chambers, Louisa G. Gordon, Robert Alexander Frank Gardiner, Declan G. Murphy, Matthew J. Roberts, John Yaxley, Nathan Lawrentschuk, Kevin Chu, Jeremy Millar, Jeremy Grummet, Ilona Juraskova

Research outputs 2022 to 2026

Background and objective: Evidence suggests that curative treatment for low-risk prostate cancer (LRPC) has no survival benefits over active surveillance (AS); thus, treatment choice becomes a value-sensitive decision. Decision aids (DAs) have the potential to facilitate this process, yet no DA has been tailored to the Australian health care system or population. This study aims to evaluate the impact of an online DA (Navigate) on the uptake of AS, quality of life, and decision-making in Australia. Methods: This parallel-group, prospective, randomised controlled trial recruited men (from May 2017 to May 2021) from participating cancer centres, via self-referral, or via clinician …

Despite genome-wide association studies (GWAS) of late-onset Alzheimer’s disease (LOAD) having identified many genetic risk loci1–3, the underlying disease mechanisms remain largely unclear. Determining causal disease variants and their LOAD-relevant cellular phenotypes has been a challenge. Here, using our approach for identifying functional GWAS risk variants showing allele-specific open chromatin, we systematically identified putative causal LOAD-risk variants in human induced pluripotent stem (iPS)-cell-derived neurons, astrocytes and microglia, and linked a PICALM LOAD-risk allele to a microglial-specific role of PICALM in lipid droplet (LD) accumulation. Allele-specific open-chromatin mapping revealed functional risk variants for 26 LOAD-risk loci, mostly …

Since 1955, a form of diabetes in lean, young (BMI < 18·5 kg/m2, age < 30 years) individuals with a history suggestive of undernutrition from before birth and throughout childhood has been described in the literature. In 1985, WHO formally classified it as malnutrition-related diabetes, but subsequently removed the classification in 1999 over a disagreement as to whether undernutrition was a sufficient risk factor to cause this type of diabetes. Emerging evidence now strongly supports the distinct classification of this unique diabetes phenotype, which is characterised by substantial impairment of pancreatic insulin secretion, with normal hepatic and peripheral insulin sensitivity, an absence of ketoacidosis, and no islet cell autoantibodies. In this consensus statement, we synthesise this evidence to produce a set of common features of the disease, proposed pathogenetic mechanisms, and suggested management and prevention strategies. During a consensus meeting in Vellore, India, in January, 2025, type 5 diabetes was proposed as the nomenclature for this distinct form of diabetes, subsequently formalised at the International Diabetes Federation (IDF) World Diabetes Congress in April, 2025. We call upon the international diabetes community to recognise this distinct form of the disease, and to support the IDF's Type 5 Diabetes Working Group and its goals to promote more research into its phenotype, pathophysiology, and treatment, which will benefit millions of patients worldwide, particularly in low-income and middle-income countries.

Faculty, Staff and Students Publications

Introduction: Chronic pancreatitis (CP) is a disease associated with chronic inflammation, fibrosis, and pain. There is a lack of tools available that facilitate early diagnosis, when intervention could prevent irreversible damage. Pilot data suggested prostaglandin E2 (PGE2) as a candidate biomarker for early CP. PGE2 activates signaling pathways that promote inflammation, pain, and fibrosis.

Methods: We assessed PGE2, metabolites, and downstream targets in pancreatic fluid collected endoscopically 0-10 (n = 110) and 10-20 (n = 111) minutes after intravenous secretin administration. PGE2 and metabolites were measured in plasma (n = 75) and urine (n = 71) from the same subjects. …

Faculty, Staff and Students Publications

Radium-223 (223Ra) is a bone-seeking, alpha-particle-emitting radionuclide that is approved for the treatment of patients with metastatic prostate cancer and is currently being tested in clinical trials for primary and metastatic cancers to the bone. 223Ra accumulates in mineralized bone areas with high bone turnover, where its effects are confined within 100 μm of the bone–marrow interface due to the short tissue penetrance of the alpha particles. A recent clinical study has shown a significantly increased fracture rate associated with the administration of 223Ra, mostly in tumor-free bones. Importantly, the biological mechanisms underlying this bone fragility remain unclear. In this …

ATP5F1A encodes the α-subunit of complex V of the respiratory chain, which is responsible for mitochondrial ATP synthesis. We describe 6 probands with heterozygous de novo missense ATP5F1A variants that presented with developmental delay, intellectual disability, and movement disorders. All variants were located at the contact points between the α- and β-subunits. Functional studies in C. elegans revealed that the variants were damaging via a dominant negative genetic mechanism. Biochemical and proteomics studies of proband-derived cells showed a marked reduction in complex V abundance and activity. Mitochondrial physiology studies revealed increased oxygen consumption, yet decreased mitochondrial membrane potential and ATP …

Lung Cancer In Patients Of African Descent: A Transcontinental Review Of Epidemiology, Disparities, Outcomes, And Opportunities For Equity In Africa, North America, South America, And The Caribbean, Elvis Obomanu, Colton Jones, Verna Vanderpuye, Nazik Hammad

Division of Internal Medicine Faculty Papers & Presentations

Lung cancer in people of African descent is characterized by transcontinental disparities driven by epidemiologic heterogeneity, systemic inequities, and unequal access to health care. Globally, lung cancer incidence and mortality rates vary; however, underdiagnosis and late-stage presentation in low- and middle-income countries obscure the true prevalence of lung cancer because of limited cancer registries and diagnostic infrastructure. In Africa, most patients with lung cancer present at an advanced stage, primarily because of health illiteracy, misdiagnosis, delayed referrals, and inadequate treatment infrastructure. Although tobacco smoking remains a dominant risk factor worldwide, African populations are disproportionately exposed to environmental and occupational hazards, …
