White Matter Connections Within The Central Sulcus Subserving The Somato-Cognitive Action Network, Georgios P Skandalakis, Evan M Gordon, Nico U F Dosenbach, Et Al.

2020-Current year OA Pubs

The somato-cognitive action network (SCAN) consists of three nodes interspersed within Penfield's motor effector regions. The configuration of the somato-cognitive action network nodes resembles the one of the 'plis de passage' of the central sulcus: small gyri bridging the precentral and postcentral gyri. Thus, we hypothesize that these may provide a structural substrate of the somato-cognitive action network. Using microdissections of 16 human hemispheres, we consistently identified a chain of three distinct plis de passage with increased underlying white matter in locations analogous to the somato-cognitive action network nodes. We mapped localizations of plis de passage into standard stereotactic space …

Narrative persuasion has been widely used in health communication campaigns and persuasive message design. However, several meta-analyses showed that the relative effectiveness of narratives in promoting behavior change was not consistently observed in the existing literature. With the goal of exploring boundary conditions of narrative effects, this study investigates the interaction effects of narrative persuasion and stages of change on promoting behavior change in the context of encouraging parents to vaccinate their children against human papillomavirus (HPV). Findings from an online experiment (N = 593) showed that non-narrative messages were more effective in bolstering behavioral intention than narrative messages among …

2020-Current year OA Pubs

Over-expression of BCL-2 defines follicular lymphoma (FL). Venetoclax (VEN), a selective BCL-2 inhibitor, has previously been evaluated with bendamustine-based chemoimmunotherapy. VEN was given continuously, resulting in promising efficacy but unacceptable toxicity. The Phase II PrE0403 study was designed to evaluate intermittent dosing of VEN (10 days per cycle) combined with obinutuzumab and bendamustine (VEN-OB) in untreated FL subjects with high-risk features defined as a FLIPI-1 score of ≥3 and/or high tumor burden by GELF criteria. A total of 56 subjects were planned to be accrued with a goal of having 51 subjects eligible to improve the historical 50% CR rate …

Intracellular Inclusions Induced By Patient-Derived And Amplified Α-Synuclein Aggregates Are Morphologically Indistinguishable, Rabab Al-Lahham, Mark E Corkins, Mohd Ishtikhar, Prakruti Rabadia, Santiago Ramirez, Victor Banerjee, Mohammad Shahnawaz

Faculty, Staff and Student Publications

Lewy Body Disease (LBD) and Multiple System Atrophy (MSA) are synucleinopathies with distinct prognoses and neuropathologies, however, with overlapping clinical symptoms. Different disease characteristics are proposed to be determined by distinct conformations of alpha-synuclein (α-Syn) aggregates, which can self-propagate and spread between cells via a prion-like mechanism. The goal of this study is to investigate whether α-syn aggregates amplified from brain and CSF samples of LBD and MSA patients using the Seed Amplification Assay (SAA) maintain α-Syn seeding properties similar to those of α-syn aggregates derived from patients' brains. To address this, SAA-amplified and un-amplified α-Syn aggregates from LBD and …

BACKGROUND: Social network data are essential and informative for public health research and implementation as they provide details on individuals and their social context. For example, health information and behaviors, such as HIV-related prevention and care, may disseminate within a network or across society. By harmonizing egocentric and digital networks, researchers may construct a sociocentric-like "fuzzy" network based on a subgroup of the population.

OBJECTIVE: We aimed to generate a more complete sociocentric-like "fuzzy" network by harmonizing alternative sources of egocentric and digital network data to examine relationships between participants in the Neighborhoods and Networks (N2) cohort study. Further, we …

Faculty, Staff and Student Publications

Research on the relationship between resistin levels, metabolic health, and obesity has produced inconsistent findings across different ethnic groups, making it unclear whether lower resistin levels are associated with these conditions in Mexican-Americans. This cross-sectional study investigated the relationship between resistin, metabolic health, and obesity in an adult Mexican-American cohort (n = 1511) using multivariable linear regression analysis. Related adipokines (leptin and adiponectin) were measured simultaneously. Participants were categorized into four groups by metabolic health (healthy/unhealthy) and obesity (obese/non-obese) status. “Metabolically unhealthy” was defined as ≥2 cardiometabolic abnormalities. Obesity was defined as a BMI ≥ 30 kg/m2. We also …

Soil-transmitted helminth (STH) infections rank among the most prevalent communicable diseases of humans, yet detection of these parasites is mostly restricted to identifying active infection through fecal examinations. Currently, there are no commercial diagnostic tools to identify a prior whipworm or hookworm exposure, and the few serological assays for roundworm infection have not been well validated for crossreactivity or infections in humans. Such diagnostic restrictions limit the range of scientific and clinical questions that surround STH exposures and their implicated relationship to chronic diseases, such as autoimmunity, allergy, and cancer. The goal of this investigation was to evaluate the diagnostic …

Rickettsial pathogens are an endemic and emergent source of disease in Texas, with a historically high rate of transmission along the United States-Mexico border. To better understand the prevalence and risk factors for spotted fever group Rickettsia (SFGR) and typhus group Rickettsia (TGR) along the Texas-Mexico border, we conducted a seroprevalence study of adults residing in Starr County, Texas (N = 616). Plasma samples were screened for IgG reactivity to SFGR and TGR using commercially available ELISA. ELISA-positive samples were confirmed using a dual spot IgG indirect immunofluorescent assay. Seropositivity was defined as having a ≥1:128 titer. Analysis was conducted …

Characterising Acute And Chronic Care Needs: Insights From The Global Burden Of Disease Study 2019, A. A. Asadi-Pooya

Department of Neurology Faculty Papers

Chronic care manages long-term, progressive conditions, while acute care addresses short-term conditions. Chronic conditions increasingly strain health systems, which are often unprepared for these demands. This study examines the burden of conditions requiring acute versus chronic care, including sequelae. Conditions and sequelae from the Global Burden of Diseases Study 2019 were classified into acute or chronic care categories. Data were analysed by age, sex, and socio-demographic index, presenting total numbers and contributions to burden metrics such as Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLD), and Years of Life Lost (YLL). Approximately 68% of DALYs were attributed to chronic …

Vega, Minal Dhamankar, Aruna Padmanabhan, Suzanne M. Miller, Kuang-Yi Wen

Department of Medical Oncology Faculty Papers

Purpose: Adjuvant endocrine therapy (AET) significantly diminishes recurrence and mortality risks in hormone receptor-positive breast cancer (BCa) patients. Nonetheless, suboptimal adherence and premature discontinuation during the initial year of treatment undermine these positive outcomes. This study aims to understand the potential diverse factors associated with perceived barriers to AET compliance at the onset of medication. Methods: We assessed perceived barriers to AET using the ASK-20 instrument for BCa patients initiating AET within 3 months. Our survey also included demographic variables (e.g., musculoskeletal symptoms) and clinical traits (e.g., medication type). Stepwise regression analyses were employed to elucidate the links between multilevel …

Age-related white matter (WM) microstructure maturation and decline occur throughout the human lifespan, complementing the process of gray matter development and degeneration. Here, we create normative lifespan reference curves for global and regional WM microstructure by harmonizing diffusion MRI (dMRI)-derived data from ten public datasets (N = 40,898 subjects; age: 3-95 years; 47.6% male). We tested three harmonization methods on regional diffusion tensor imaging (DTI) based fractional anisotropy (FA), a metric of WM microstructure, extracted using the ENIGMA-DTI pipeline. ComBat-GAM harmonization provided multi-study trajectories most consistent with known WM maturation peaks. Lifespan FA reference curves were validated with test-retest data …

2020-Current year OA Pubs

BACKGROUND: There are high incidence and mortality rates of breast cancer in Brazil. Brazilian's social and economic disparities, along with complexities of its health system pose challenges to the appropriate implementation of mammography screening as a public policy for the population. In 2015, the Ministry of Health updated the recommendations for the early detection of breast cancer, which had, until then, been based on specialists' consensus, maintaining biennial screening mammography for women aged 50-69 years. However, the screening coverage did not exceed 25% of the expected number of exams for the Brazilian population who use the public health system. The …

The Dialysis Foot- The Impact Of Presenting Estimated Glomerular Filtration Rate On Clinical Outcomes In Patients Hospitalized With Diabetic Foot Infections, Arthur Tarricone, Tyler L Coye, Allen Gee, Bijan Najafi, Michael C Siah, Lawrence A Lavery

Center on Aging Staff Publications

To evaluate the association between presenting estimated glomerular filtration rate (eGFR) and clinical outcomes in patients hospitalized with diabetic foot infections. This retrospective cohort study included 344 patients with moderate to severe diabetic foot infections. Patients were categorized into three groups based on presenting estimated eGFR: eGFR ≥60 (eGFR >60 mL/min), eGFR 30-60 (eGFR 30-60 mL/min) and eGFR < 30 (eGFR < 30 mL/min). Outcomes assessed included wound healing, time to heal, re-infection, amputation, mortality and re-hospitalization for infection. Compared with patients with eGFR < 30, patients with eGFR ≥60 had significantly lower rates of retinopathy, peripheral arterial disease and use of beta blockers or calcium channel blockers. Glycated haemoglobin levels were inversely related to eGFR, decreasing as eGFR severity increased. Haemoglobin levels were significantly lower, and inflammatory markers (ESR and CRP) were significantly higher in patients with eGFR < 30. There were no significant differences among eGFR groups in rates of wound healing, time to heal, re-infection or amputation. However, mortality increased with decreasing eGFR (1.9% in eGFR ≥60 vs. 3.2% in eGFR 30-60 vs. 8.1% in eGFR < 30; p = 0.04). Similarly, re-hospitalization for infection at a different site also increased with decreasing eGFR (20.5% in eGFR ≥60 vs. 28.1% in eGFR 30-60 vs. 48.4% in eGFR < 30; p <  0.01). In diabetic foot infections, presenting eGFR severity did not affect rates of wound healing, time to heal, re-infection or amputation. However, decreasing eGFR was associated with increased mortality and re-hospitalization for infection at a different site. In this study, presenting eGFR was not a predictive value for wound healing or time until healing, however was associated with rehospitalization and overall mortality this diabetic foot population.

Serendipitous Supernormality, Behzad B. Pavri, Eitan Frankel

Division of Cardiology Faculty Papers

We describe a patient who underwent AV node modification to create complete heart block in the setting of incessant, ablation-and-drug-refractory, symptomatic atypical atrial flutter. His dual chamber defibrillator (previously implanted for resuscitated cardiac arrest) was programmed to the VVIR mode at a faster pacing rate of 85 bpm. Serendipitously, this rate was an almost exact factorial of his flutter rate of 250-260 bpm. This resulted in every 6th flutter wave falling in the supernormal period, resulting in fixed-coupled supraventricular bigeminy and trigeminy in the setting of complete heart block. Reprogramming the pacing rate to 75 bpm abolished bigeminy and trigeminy.
