Abstract
PURPOSE/OBJECTIVE(S) The objective of this study was to determine the impact of the COVID-19 pandemic on academic productivity in oncology as measured by conference abstracts, journal publications and individual authorship trends. MATERIALS/METHODS Using a reference time frame of 2018 to 2022, we obtained data on the number of abstracts and articles submitted and published from a selection of oncology conferences and journals. To assess individual authorship patterns, we randomly selected 200 articles from 2018 (i.e., the 'index paper') and tracked publications over subsequent years for the first or last authors. Linear time-trend analyses and independent two-sample t-tests were used to assess changes in academic productivity over time, and univariable and multivariable linear regression were used to analyze individual factors predictive of publication rates, including gender, continent, specialty, MD vs. non-MD, and career status (early if within 5 years of training completion vs. late for all others). RESULTS Data on submitted and published abstracts were available from 5 and 7 conferences, respectively. Both abstract categories demonstrated decreasing values over time but not statistically significant: conference submissions decreased from 15,308 in 2018 to 13,623 in 2022, (p = 0.11), and published abstracts decreased from 13,111 to 11,848, respectively (p = 0.16). Journal submissions were available from 6 journals and increased from 14,142 in 2018 to a peak of 20,241 in 2020 (2018 vs. 2020: p<0.001), and then declined to 15,650 in 2021. Journal publications from 10 journals showed no clear trends over time (p = 0.64). For the author-level analysis, of the 200 authors randomly selected, the majority were male (66.5%), from North America (55.5%), with an MD degree (80.9%, 131/162) and late career (86.6%, 129/149). Most common specialties included surgery (29%), radiation oncology (18.5%), epidemiology/public health (11%) and medical oncology (10%). For articles authored per year, there was no linear trend detected (p = 0.51), although mean number of publications per author peaked in 2020/2021 (papers/year for 2018-2022: 18.1, 18.1, 20.1, 21.2, 19.6). On univariable analysis, factors significantly associated with increasing publication rates were male gender, last author position on index paper, late career status, MDs, speciality of surgery or public/health epidemiology, and authors from Asia (all p<0.01). On multivariable analysis, factors remaining significantly predictive were late career status, MDs, specialty of surgeons or public health/epidemiologists, and authors from Asia (all p<0.01). CONCLUSION Conference submissions and publications trended downward from 2018 to 2022. Journal submissions peaked overall in 2020, but did not translate to increases in journal publication rates. Disparities in publication trends were found, based on speciality and geographic regions, including a negative impact on early-career researchers.

Abstract
We have previously reported that the α1 subunit of sodium-potassium adenosine triphosphatase (Na/K-ATPase), acts as a receptor and an amplifier for reactive oxygen species, in addition to its distinct pumping function. On this background, we speculated that the blockade of Na/K-ATPase-induced ROS amplification with a specific peptide, pNaKtide, might attenuate the development of steatohepatitis. To test this hypothesis, pNaKtide was administered to a murine model of NASH: the C57Bl6 mouse fed a "western" diet containing high amounts of fat and fructose. The administration of pNaKtide reduced obesity as well as hepatic steatosis, inflammation and fibrosis. Of interest, we also noted a marked improvement in mitochondrial fatty acid oxidation, insulin sensitivity, dyslipidemia and aortic streaking in this mouse model. To further elucidate the effects of pNaKtide on atherosclerosis, similar studies were performed in ApoE knockout mice also exposed to the western diet. In these mice, pNaKtide not only improved steatohepatitis, dyslipidemia, and insulin sensitivity but also ameliorated significant aortic atherosclerosis. Collectively, this study demonstrates that the Na/K-ATPase/ROS amplification loop contributes significantly to the development and progression of steatohepatitis and atherosclerosis. Furthermore, this study presents a potential treatment, the pNaKtide, for the metabolic syndrome phenotype.

Abstract
Background: Pregnant women are at an increased risk for anxiety and depression, but a majority of women go untreated due to a high rate of undetected symptoms. The 4-item Patient Health Questionnaire (PHQ-4) is an ultrabrief screening instrument for anxiety and depression with sound psychometric properties demonstrated in the general population and primary care, but not among pregnant women. The aim of this study was to provide initial evidence of the validity and reliability of the PHQ-4 among pregnant women. Materials and Methods: Data from an international sample of 1148 pregnant women who participated in an online cross-sectional survey were examined using a confirmatory factor analysis (CFA) and multigroup analysis approaches. Average chronological and gestational ages were 27.7 years old (standard deviation [SD] = 6.5) and 16.8 weeks (SD = 10.6), respectively. Participants were from diverse cultural backgrounds and English and Spanish speaking (n = 587 and n = 561, respectively). Results: CFA reflected two distinct factors, which accounted for 59% of the proportion of variance in the two anxiety items and 50% in the two depression items. Coefficient H values of 0.74 for anxiety and 0.70 for depression suggested good factor reliability. Conclusions: This is the first study demonstrating initial evidence supporting the validity and reliability of the PHQ-4 in pregnant women. Should this study be replicated, a clinical interview, which is the gold standard procedure, should be included. Regardless, the PHQ-4 may be a useful ultrabrief resource for maternal mental health clinicians and health care providers who need to identify potential cases of anxiety and depression in pregnant women using efficient and evidence-based tools.

Abstract
Objective Subglottic squamous cell carcinoma is a rare subsite of laryngeal cancer that behaves more aggressively and portends a worse prognosis. Using a population-based cancer registry, our objective was to report overall survival (os) and laryngectomy-free survival (lfs) in patients diagnosed with subglottic squamous cell carcinoma, and to determine whether primary laryngectomy results in improved survival. Methods This retrospective population-based study considered patients with a new diagnosis of squamous cell carcinoma in the province of Ontario over a 15-year period (1995-2009). The Ontario Cancer Registry was examined for patients with the diagnosis of interest during the period of interest. Linked population-based databases were used to obtain patient demographics, comorbidity measures, staging, survival, and primary treatment with laryngectomy. Results Of 4927 patients identified to have laryngeal carcinoma, 89 were defined as having primary subglottic carcinoma (1.8%). In the subglottic cohort, 68 patients were men (76.4%), and mean age at diagnosis was 68 years (interquartile range: 60-77 years). The 5-year os was 47.2%, and the 5-year lfs was 31.5%. In 13 patients (15%), the primary treatment was laryngectomy, which, compared with primary radiation, did not predict for improved os. No differences in os or lfs were observed during the 15-year study period (os p = 0.42, lfs p = 0.83). Conclusions The survival of patients with subglottic carcinoma is poor and has remained stable over time (1995-2009). Compared with primary radiation, primary treatment with laryngectomy does not appear to improve os.

Abstract
The potential role of adiponectin, leptin, IGF-1, and tumor necrosis factor alpha (TNF-α) as biomarkers in colorectal adenoma is not clear. Therefore, we aimed to investigate the blood serum levels of these biomarkers in colorectal adenoma. The case-control study consisted of serum from 180 African American patients with colon adenoma (cases) and 198 healthy African Americans (controls) at Howard University Hospital. We used ELISA for adiponectin, leptin, IGF-1, and TNF-α detection and quantification. Statistical analysis was performed by t-test and multivariate logistic regression. The respective differences in median leptin, adiponectin, IGF-1, and TNF-α levels between control and case groups (13.9 vs. 16.4), (11.3 vs. 46.0), (4.5 vs. 12.9), and (71.4 vs. 130.8) were statistically significant (P < 0.05). In a multivariate model, the odds ratio for adiponectin, TNF-α, and IGF-1 were 2.0 (95% CI = 1.6-2.5; P < 0.001), 1.5 (95% CI = 1.5(1.1-2.0); P = 0.004), and 1.6 (95% CI = 1.3-2.0; P < 0.001), respectively. There was a positive correlation between serum adiponectin and IGF-1 concentrations with age (r = 0.17, P < 0.001 and r = 0.13, P = 0.009), TNF-α, IGF-1, and leptin concentration with body mass index (BMI) (r = 0.44, P < 0.001; r = 0.11, P = 0.03; and r = 0.48, P < 0.001), respectively. Also, there was a negative correlation between adiponectin and leptin concentrations with BMI (r = -0.40, P < 0.001), respectively. These data support the hypothesis that adiponectin, IGF-1, and TNF-α high levels correlate with higher risk of colon adenoma and can thus be used for colorectal adenomas risk assessment.

Abstract
Background:
We have previously reported that the α1 subunit of the sodium potassium adenosine triphosphatase (Na/K-ATPase) acts as an amplifier for reactive oxygen species (ROS) in addition to its ion pumping function. We have also shown that blockade of this amplification with a novel peptide, pNaKtide, ameliorates oxidative stress and obesity in mice subjected to a high-fat diet.
Hypothesis:
Given the importance of oxidative stress in the pathophysiology of atherosclerosis, we chose to examine whether pNaKtide might be effective in ameliorating dyslipidemia and atherosclerosis in ApoE -/- mice.
Methods:
pNaKtide was administered in ApoE -/- mouse fed western diet. 25 mg/Kg pNaKtide was administered intraperitoneally once every 7 days. Lipid profile, glucose insulin levels, and ROS levels were measured. Aortas were dissected and quantification of aortic lesions was done.
Results:
Our results show that pNaKtide improved glucose tolerance and HOMA-IR scores in ApoE-/- mice fed a western diet (p<0.05). Also, pNaKtide administered to these mice significantly decreased plasma ALT, triglycerides, FFA, and LDL levels. Further, our results show that ApoE -/- mice fed a western diet had decreased plasma HDL levels and this decrease was reversed by pNaKtide. Plasma ROS levels were significantly attenuated by pNaKtide treatment. Mice fed a western diet had increased plaque size. Plaque size was significantly decreased by pNaKtide treatment.
Conclusion:
This study suggests that the Na/K-ATPase/ROS signaling cascade is a possible mechanism for the development of dyslipidemia and atherosclerosis associated with the metabolic syndrome phenotype and pNaKtide presents a potential novel treatment for these pathologies.

Abstract
Reactive oxygen species (ROS) have gained attention with mounting evidence of their importance in cell signaling and various disease states. ROS is produced continuously as a natural by-product of normal oxygen metabolism. However, high levels ROS causes oxidative stress and damage to biomolecules. This results in loss of protein function, DNA cleavage, lipid peroxidation, or ultimately cell injury or death. Obesity has become a worldwide epidemic; studies show fat accumulation is associated with increased ROS and oxidative stress. Evidence exists supporting oxidative stress as a factor driving forward insulin resistance (IR), potentially resulting in diabetes. Na+/K+-ATPase signaling is also a potential source of ROS promoting oxidative stress. The best way to observe radical species in biological systems is electron paramagnetic resonance spectroscopy with spin trapping. EPR spin trapping is an important technique to study the mechanisms driving disease states attributed to ROS.

Abstract
We have previously reported that the α1 subunit of sodium potassium adenosine triphosphatase (Na/K-ATPase), acts as a receptor and an amplifier for reactive oxygen species, in addition to its distinct pumping function. On this background, we speculated that blockade of Na/K-ATPase-induced ROS amplification with a specific peptide, pNaKtide, might attenuate the development of steatohepatitis. To test this hypothesis, pNaKtide was administered to a murine model of NASH: the C57Bl6 mouse fed a “western” diet containing high amounts of fat and fructose. The administration of pNaKtide reduced obesity as well as hepatic steatosis, inflammation and fibrosis. Of interest, we also noted marked improvement in mitochondrial fatty acid oxidation, insulin sensitivity, dyslipidemia and aortic streaking in this mouse model. To further elucidate the effects of pNaKtide on atherosclerosis, similar studies were performed in ApoE knockout mice also exposed to the western diet. In these mice, pNaKtide not only improved steatohepatitis, dyslipidemia, and insulin sensitivity, but also ameliorated significant aortic atherosclerosis. Collectively, this study demonstrates that the Na/K-ATPase/ROS amplification loop contributes significantly to the development and progression of steatohepatitis and atherosclerosis. And furthermore, this study presents a potential treatment, the pNaKtide, for the metabolic syndrome phenotype.

Abstract
Objectives: Metabolic syndrome causes complications like cardiovascular disease and type 2 diabetes mellitus (T2DM). As metabolic syndrome develops, altered levels of cytokines and microRNAs (miRNA) are measurable in the circulation. We aimed to construct a panel detecting abnormal levels of cytokines and miRNAs in patients at risk for metabolic syndrome. Methods: Participants included 54 patients from a Family Medicine Clinic at Marshall University School of Medicine, in groups of: Control, Obese, and Metabolic Syndrome (MetS). Results: Serum levels of leptin, adiponectin, leptin: adiponectin ratio, IL-6, six miRNAs (320a, 197-3p, 23-3p, 221-3p, 27a-3p, and 130a-3p), were measured. Among the three groups, leptin, and leptin: adiponectin ratio, and IL-6 levels were highest in MetS, and levels in Obese were greater than Control (p>0.05). Adiponectin levels were lower in Obese compared to Control, but lowest in MetS (p<0.05). MiRNAs levels were lowest in MetS, and levels in Obese were lower than Control (p>0.05). Conclusion: Our results support the clinical application of biomarkers in diagnosing early stage MetS, which will enable attenuation of disease progression before onset of irreversible complications. Since West Virginians are high-risk for developing MetS, our biomarker panel could reduce the disease burden on our population.

Abstract
Ethical principles in conducting technology-based research require effective and efficient methods of ensuring adequate informed consent. This study examined how well participants understood the informed consent form for an online postpartum depression trial. Pregnant women ( N = 1,179) who consented to the trial demonstrated an understanding of the purpose (86.1%) and procedures of the study (75.8%), and the minimal risks associated with answering sensitive questions online (79%). Almost all (99.6%) understood that psychological treatment was not offered. Participants with current depression incorrectly indicated that participation would replace current psychological treatment relative to participants with a lifetime or no depression history (19.6% vs. 13.5 % vs. 10.4%, respectively) and that there were no associated risks with participation (29.6% vs.17.6% vs. 16.7%, respectively). Findings provide initial evidence that most individuals who seek online psychological resources are informed consumers.

Abstract
Hepcidin, a phase II reactant secreted by hepatocytes, regulates cellular iron levels by increasing internalization of ferroportin- a transmembrane protein facilitating egress of cellular iron. Chronic low-grade inflammatory states, such as obesity, have been shown to increase oxidative stress and enhance hepcidin secretion from hepatocytes and macrophages. Heme-heme oxygenase (HO) is a stress response system, the induction of which reduces oxidative stress thereby abating patho-physiological conditions such as obesity and metabolic syndrome.8 week old male obese (ob) mice and their age- and sex-matched lean mice were used as controls. CoPP was administered intraperitoneally once a week (3 mg/kg) for 6 weeks to obese mice. CoPP plus stannous mesoporphyrin (SnMP) was administered intraperitoneally three times a week (20 mg/kg) for 6 weeks.
We investigated the effects of HO-1 induction on hepatic hepcidin levels and on iron homeostasis in tissues from lean and obese mice. Obese mice exhibited hyperglycemia along with increased levels of pro-inflammatory cytokines (MCP-1, IL-6, p<0.05), oxidative stress and increased hepatic hepcidin levels (p<0.05). Enhancement of hepcidin was reflected in the reduced expression of ferroportin in obese mice (p<0.05). Further, our results showed attenuation of insulin receptor phosphorylation and attenuation of metabolic regulators including pAMPK, pAKT and pLKB1. Cobalt protoporphyrin (CoPP)-induced HO-1 up-regulation in obese mice and reversed these pathophysiological alterations (p<0.05) while attenuating hepatic hepcidin levels and enhancing ferritin expression. These effects of CoPP were prevented in obese mice concurrently exposed to an inhibitor of HO (SnMP) (p<0.05).
Taken together, our results highlight a modulatory effect of HO on iron homeostasis mediated through the suppression of hepatic hepcidin in conjunction with the rescue of cellular ferritin levels. Therefore, these findings may prove an effective strategy in treating the metabolic consequences of obesity including alteration of liver iron homeostasis.

Abstract
Introduction/Background:
Obesity increases levels of certain biomarkers related to metabolic syndrome (leptin and TNF-α) in Appalachian women. It also leads to vascular dysfunction and atherosclerosis, which is assessed by levels of inflammatory markers angiotensin II (Ang II), a powerful vasoconstrictor, and serum adiponectin. We previously demonstrated a marked increase in levels of inflammatory markers in humans and mice with hypertension, obesity, and diabetes, and hypothesize that a high-BMI subject would present with increased levels of angiotensin II, leptin, and TNF-α, as well as decreased adiponectin.
Methods:
Serum adiponectin, Ang II, leptin, and TNF-α were assayed in female Appalachian subjects. Linear regression analysis was used to analyze the relationship between BMI, leptin, adiponectin, and Ang II. Nonlinear regression was used to determine the odds ratio and confidence intervals. The effect on murine pre-adipocytes was also measured.
Results:
Lipidomic analysis revealed a significant increase in Ang II among high-BMI females (50-72) compared to lower-BMI subjects (32-45) (p<0.05). Treatment of murine pre-adipocytes with Ang II decreased serum adiponectin levels and increased adipogenesis by 70% (p<0.05), implicating both Ang II and oxidative stress as factors in the pathogenesis of BMI-related disease. Serum leptin and TNF-α were significantly increased in high-BMI subjects (p<0.05) compared to lower-BMI subjects, while adiponectin levels were decreased (p<0.05) in high-BMI subjects compared to lower-BMI subjects.
Discussion/Conclusions:
Increased BMI in Appalachian females correlates with an increase in Ang II level, serum TNF-α, and leptin expression, and a decrease in serum adiponectin. This represents a novel mechanism by which high-BMI females with controlled blood pressure remain sensitive to the development of atherogenesis, vascular dysfunction, and metabolic syndrome.

Abstract
Abstract
Background and Aim: The potential role of Adiponectin, Leptin, IGF1 and TNFα as biomarker in colon adenoma has not been studied. Therefore, we investigated the blood serum levels of these biomarkers in colorectal adenoma.
Method: The case-control study consisted of 198 African American patients with colon adenoma (cases) and 198 healthy individuals (controls) at Howard University Hospital. We used Elisa for biomarkers detection. Statistical analysis was performed by t-test and multivariate logistic regression.
Results: The differences in median leptin, Adiponectin, IGF1 and TNFα levels between control and case groups (6.7 vs.16.4), (11.3 vs.46.0), (4.5 vs.12.9) and (71.4 vs. 130.8) were statistically significant (p<0.05), respectively. In a multivariate model, the odds ratio (ORs) for Adiponectin, TNFα and IGF1 were 2.0 (95% CI = 1.6-2.5; P≤0.001), 1.5 (95% CI = 1.5- 2.0; P 0.004) and 1.6 (95% CI = 1.3-2.0; P≤ 0.001), respectively. There were positive correlations between serum Adiponectin and IGF1 concentrations with age (r = 0.17, P≤ 0.001 and r = 0.13, P = 0.009), also between TNFα, IGF1 and Leptin concentration with Body Mass Index (BMI) (r = 0.44, P≤ 0.001 and r = 0.11, P = 0.03; r = 0.48, P≤0.001), respectively. There was a negative correlation between Adiponectin concentration and BMI (r = -0.40, P≤0.001), respectively.
Conclusion: These data support the hypothesis that serum Adiponectin, IGF1 and TNFα are risk biomarkers for noninvasive detection of colorectal adenomas.

Abstract
Background Obesity, an epidemic among West Virginia children, as well as insulin resistance (IR), is well-established contributors to nonalcoholic steatohepatitis (NASH). Progression of NASH can lead to hepatic fibrosis and cirrhosis, making early detection imperative. The standard for diagnosing NASH is histologically via liver biopsy, which is highly invasive and generally contraindicated in children. By studying serum biomarkers associated with NASH, we aim to identify high risk children who can benefit from a less invasive, alternative approach to the early detection of NASH. Methods Seventy one children were prospectively recruited and divided into 3 groups: normal weight without IR (control), obese without IR, and obese with IR. Serum samples were drawn for each patient and biomarker levels were assessed via ELISA kits. Results Obese without IR and obese with IR patients had significantly elevated levels of lipid metabolism and accumulation markers (FGF-21, NEFA, FATP5, ApoB), oxidative stress markers (dysfunctional HDL, 8-Isoprostane), inflammatory markers(dysfunctional HDL, CK-18) and apoptosis markers (CK-18) compared to control patients (p<0.02). Bilirubin (an antioxidant) was significantly decreased in the obese without IR and obese with IR patients compared to control (p<0.02). Conclusion This study showed a correlation between obesity, IR, and biomarkers associated with NASH in pediatrics patients from West Virginia, with obese with IR patients showing the strongest correlation. These findings support the clinical application of these serum biomarkers as a less invasive method for early detection of NASH and hepatic fibrosis.

Abstract
OBJECTIVES Diabetic cardiomyopathy (DCM) is an established complication of diabetes mellitus. In West Virginia, the especially high incidence of diabetes and heart failure validate the necessity of developing new strategies for earlier detection of DCM. Since most DCM patients remain asymptomatic until the later stages of the disease when the fibrotic complications become irreversible, we aimed to explore biomarkers that can identify early-stage DCM. METHODS The patients were grouped into 4 categories based on clinical diabetic and cardiac parameters: Control, Diabetes (DM), Diastolic dysfunction (DD), and Diabetes with diastolic dysfunction (DM+DD), the last group being the preclinical DCM group. RESULTS Echocardiography images indicated severe diastolic dysfunction in patients with DD+DM and DD compared to DM or control patients. In the DM and DM+DD groups, TNFα, isoprostane, and leptin were elevated compared to control (p<0.05), as were clinical markers HDL, glucose and hemoglobin A1C. Fibrotic markers IGFBP7 and TGF-β followed the same trend. The Control group showed higher beneficial levels of adiponectin and bilirubin, which were reduced in the DM and DM+DD groups (p<0.05). CONCLUSION The results from our study support the clinical application of biomarkers in diagnosing early stage DCM, which will enable attenuation of disease progression prior to the onset of irreversible complications.

Abstract
BACKGROUND Recent reports suggest a decline over time in the survival of patients newly diagnosed with laryngeal cancer in spite of developments in treatment practices. Our study set out to determine whether the survival of patients with laryngeal cancer in Ontario has changed over time. METHODS This population-based cohort study of patients diagnosed with laryngeal cancer in the province of Ontario between 1995 and 2007 used data extracted from linked provincial administrative and registry databases. Its main outcomes were overall survival, laryngectomy-free survival, and survival ratio relative to an age- and sex-matched general population. RESULTS The 4298 patients newly diagnosed with laryngeal cancer during the period of interest were predominantly men (n = 3615, 84.1%) with glottic cancer (n = 2787, 64.8%); mean age in the group was 66 years (interquartile range: 59-74 years). Patient demographics did not significantly change over time. Overall, 5-year survival was 57.4%; laryngectomy-free survival was 45.4%. Comparing patients from three eras (1995-1998, 1999-2003, 2004-2007) and adjusting for age, sex, and comorbidity status, we observed no differences in overall survival or laryngectomy-free survival over time. The 5-year relative survival ratio for patients with laryngeal cancer compared with an age- and sex-matched group from the general population was 81.1% for glottic cancer and 44.5% for supraglottic cancer. CONCLUSIONS In patients with a new diagnosis of laryngeal cancer, overall and laryngectomy-free survival have remained unchanged since the mid-1990s. New methods to improve survival and the rate of laryngeal preservation in this patient population are needed.
