2020-Current year OA Pubs

BACKGROUND: Incidental and screening-identified lung nodules are common, and a bronchoscopic evaluation is frequently nondiagnostic. The Percepta Genomic Sequencing Classifier (GSC) is a genomic classifier developed in current and former smokers which can be used for further risk stratification in these patients. Percepta GSC has the capability of up-classifying patients with a pre-bronchoscopy risk that is high (> 60%) to "very high risk" with a positive predictive value of 91.5%. This prospective, randomized decision impact survey was designed to test the hypothesis that an up-classification of risk of malignancy from high to very high will increase the rate of referral …

Transcranial Stimulation Of Alpha Oscillations Up-Regulates The Default Mode Network, Kevin J Clancy, Jeremy A Andrzejewski, Yuqi You, Jens T Rosenberg, Mingzhou Ding, Wen Li

Faculty, Staff and Student Publications

The default mode network (DMN) is the most-prominent intrinsic connectivity network, serving as a key architecture of the brain's functional organization. Conversely, dysregulated DMN is characteristic of major neuropsychiatric disorders. However, the field still lacks mechanistic insights into the regulation of the DMN and effective interventions for DMN dysregulation. The current study approached this problem by manipulating neural synchrony, particularly alpha (8 to 12 Hz) oscillations, a dominant intrinsic oscillatory activity that has been increasingly associated with the DMN in both function and physiology. Using high-definition alpha-frequency transcranial alternating current stimulation (α-tACS) to stimulate the cortical source of alpha oscillations, …

Psychosis-Induced Exertional Rhabdomyolysis Without Acute Kidney Injury Or Myoglobinuria., Joann M Butkus, Mackenzie Kramer, Vincent Chan, Eunha Kim

Abington Jefferson Health Papers

BACKGROUND Rhabdomyolysis is a clinical syndrome that results from skeletal muscle breakdown and the release of intracellular enzymes into systemic circulation [1,2]. We present a case of non-traumatic rhabdomyolysis with transaminitis, without myoglobinuria or acute kidney injury. Cases reports of rhabdomyolysis with elevation of serum creatine kinase (hyperCKemia) in the absence of myoglobinuria or renal failure are limited in the literature.

CASE REPORT A 21-year-old man presented to the Emergency Department following an acute psychotic episode. One week earlier, his bloodwork had been within normal limits. Biochemical investigations on admission revealed hyperCKemia (590 000 U/L), transaminitis (AST, 628; ALT, 160), …

Journal Articles: Pulmonary & Critical Care Med

Background: The club cell secretory protein (CC16) has anti-inflammatory and antioxidant effects, and low CC16 serum levels have been associated with both risk and progression of COPD, yet the interaction between smoking and CC16 on lung function outcomes remains unknown.

Methods: Utilizing cross-sectional data on United States veterans, CC16 serum concentrations were measured by ELISA and log transformed for analyses. Spirometry was conducted and COPD status was defined by post-bronchodilator FEV₁/FVC ratio < 0.7. Smoking measures were self-reported on questionnaire. Multivariable logistic and linear regression were employed to examine associations between CC16 levels and COPD, and lung function with adjustment for covariates. Unadjusted Pearson correlations described relationships between CC16 level and lung function measures, pack-years smoked, and years since smoking cessation.

Results: The study population (N = 351) was mostly male, white, with an average age over 60 years. An interaction between CC16 and smoking status on …

Open Access Publications

In healthy hosts the gut microbiota is restricted to gut tissues by several barriers some of which require MyD88-dependent innate immune sensor pathways. Nevertheless, some gut taxa have been reported to disseminate to systemic tissues. However, the extent to which this normally occurs during homeostasis in healthy organisms is still unknown. In this study, we recovered viable gut bacteria from systemic tissues of healthy wild type (WT) and MyD88

Nephrology Articles

BACKGROUND: Acute kidney injury (AKI) in deceased donors is not associated with graft failure (GF). We hypothesize that hemodynamic AKI (hAKI) comprises the majority of donor AKI and may explain this lack of association.

METHODS: In this ancillary analysis of the Deceased Donor Study, 428 donors with available charts were selected to identify those with and without AKI. AKI cases were classified as hAKI, intrinsic (iAKI), or mixed (mAKI) based on majority adjudication by three nephrologists. We evaluated the associations between AKI phenotypes and delayed graft function (DGF), 1-year eGFR and GF. We also evaluated differences in urine biomarkers among …

A Right Atrial Mass With Fever And Cutaneous Nodules, Feng Gao, Stephanie Koh, Sara Taveras-Alam, Umair Khalid

Faculty, Staff and Student Publications

Primary cardiac tumors, although exceedingly rare, should be considered in the differential diagnosis during workup of any cardiac mass. Extranodal cardiac lymphomas have a natural aggressive course due to delayed diagnosis. We present a 71-year-old male with a dual-chamber pacemaker who presented with fevers and new cutaneous nodules. He was found to have a right atrial primary anaplastic large-cell lymphoma and had a complete metabolic response after chemotherapy. Our case highlights the importance of a multimodality approach in the diagnosis of cardiac tumors and during follow-up after treatment.

A Retrospective Cohort Study Assessing Acute Kidney Injury And Renal Recovery Among Septic Patients Empirically Treated With Vancomycin Piperacillin–Tazobactam Versus Vancomycin Cefepime, Brian Pacca Elliott, Michael M. Tang, Joshua Alexander Madden, Ronald J. Markert, Steven Dale Burdette, Craig Matthew Pleiman, Emily Claire Speelmon

Internal Medicine Faculty Publications

Vancomycin plus piperacillin-tazobactam (VPT) is a commonly used antimicrobial regimen for septic patients. VPT is more nephrotoxic than other regimens such as vancomycin plus cefepime (VC) when given over several days. This risk of nephrotoxicity is less clear when VPT is given for initial empiric therapy in sepsis and de-escalated quickly based on evolving clinical information. The objective of this study was to assess nephrotoxicity among septic patients empirically treated with either VPT or VC at initial clinical presentation. We conducted a retrospective study of septic patients who received VPT or VC within 12 h of presentation to the emergency …

Whistling Scrotum: An Unusual Presentation Of Pneumomediastinum In The Setting Of An Open Scrotal Wound, Brant Bickford, Andrew J. Berglund, Ronald J. Markert, Hari Polenakovik

Internal Medicine Faculty Publications

BACKGROUND Pneumoscrotum is a rare clinical occurrence in which air accumulates in the scrotum. The origin of air is primarily from trauma, but spontaneous pneumoscrotum can develop from gastrointestinal or pulmonary sources. Physical examination of pneumoscrotum typically includes crepitus of the perineal region and scrotal swelling and associated findings depending on the origin of the free air. However, pneumoscrotum in the setting of a scrotal wound, which allows air to pass freely outside the body, has not been previously documented in the literature. CASE REPORT A 72-year-old man who recently underwent a scrotal incision and drainage for recurrent epididymitis presented …

Journal Articles: Epidemiology

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) ranks first among liver diseases in Western countries. NAFLD is typically associated with obesity and diabetes, however it also develops in lean individuals without metabolic syndrome. The prevalence of lean NAFLD is 7 percent in the U.S. and 25-30 percent in some Asian countries. NAFLD starts with excess liver fat accumulation (NAFL), progresses to nonalcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma (HCC). The pathogenesis of lean NASH-HCC and how it differs from obese NASH-HCC is not well understood.

METHODS: In this work, we generated a mouse model of lean and obese NASH-HCC using a …

Brain Antigens Stimulate Proliferation Of T Lymphocytes With A Pathogenic Phenotype In Multiple Sclerosis Patients, Assaf Gottlieb, Hoai Phuong T Pham, John William Lindsey

Faculty, Staff and Student Publications

A method to stimulate T lymphocytes with a broad range of brain antigens would facilitate identification of the autoantigens for multiple sclerosis and enable definition of the pathogenic mechanisms important for multiple sclerosis. In a previous work, we found that the obvious approach of culturing leukocytes with homogenized brain tissue does not work because the brain homogenate suppresses antigen-specific lymphocyte proliferation. We now report a method that substantially reduces the suppressive activity. We used this non-suppressive brain homogenate to stimulate leukocytes from multiple sclerosis patients and controls. We also stimulated with common viruses for comparison. We measured proliferation, selected the …

Validity Evidence For The Male Depression Risk Scale-22 (Mdrs-22) In Younger And Older Adult Males, Montgomery T. Owsiany

Graduate Theses, Dissertations, and Problem Reports (ETD)

Men are two times less likely to be diagnosed with major depressive disorder than women. However, suicide rates are nearly four times higher in men than women, increasing to six times when comparing older men to older women. Given that affective disorders are present in most individuals who die by suicide, investigators have begun researching the possibility that depression presents differently in individuals who adhere to traditional masculine norms, leading to the conceptualization of masculine depression. Presently, one assessment for masculine depression shows strong reliability and validity evidence: the Male Depression Risk Scale-22 (MDRS-22). Despite burgeoning validity evidence for the …

Impact Of Early Life Stress And Cannabidiol On Behavior And Corticosterone Levels In Male And Female Rats, Marina Yacoub

Capstone Showcase

Organisms must maintain homeostasis that is regulated internally and externally. Fluctuation in homeostasis causes stress. Corticosterone, the main stress hormone in rodents, increases following exposure to acute stressors, such as being placed in a restrainer. However, early developmental experiences including maternal separation shape the development of the stress response into adulthood and impact the expression of depressive and anxiety-like behaviors. Many factors can shape the body's response to stress, for example, a rodent's previous exposure to a past stressor can affect their present behavior. Several studies have shown that female rats have lower or no changes in corticosterone levels compared …

Journal Articles: Infectious Diseases

Pediatric household contacts (HHCs) of patients with multidrug-resistant TB (MDR-TB) are at high risk of infection and active disease. Evidence of caregiver willingness to give MDR-TB preventive therapy (TPT) to children is limited.METHODS This was a cross-sectional study of HHCs of patients with MDR-TB to assess caregiver willingness to give TPT to children aged <13 years.RESULTS Of 743 adult and adolescent HHCs, 299 reported caring for children aged <13 years of age. The median caregiver age was 35 years (IQR 27-48); 75% were women. Among caregivers, 89% were willing to give children MDR TPT. In unadjusted analyses, increased willingness was associated with TB-related knowledge (OR 5.1, 95% CI 2.3-11.3), belief that one can die of MDR-TB (OR 5.2, 95% CI 1.2-23.4), concern for MDR-TB transmission to child (OR 4.5, 95% CI 1.6-12.4), confidence in properly taking TPT (OR 4.5, 95% CI 1.6-12.6), comfort telling family about TPT (OR 5.5, 95% CI 2.1-14.3), and willingness to take TPT oneself (OR 35.1, 95% CI 11.0-112.8).CONCLUSIONS A high percentage of caregivers living with MDR- or rifampicin-resistant TB patients were willing to give children a hypothetical MDR TPT. These results provide important evidence for the potential uptake of …
