Background: Schizophrenia (SCZ) and bipolar disorder (BIP) are debilitating neuropsychiatric disorders, collectively affecting 2% of the world's population. Recognizing the major impact of these psychiatric disorders on the psychosocial function of more than 200 000 US Veterans, the Department of Veterans Affairs (VA) recently completed genotyping of more than 8000 veterans with SCZ and BIP in the Cooperative Studies Program (CSP) #572.

Methods: We performed genome-wide association studies (GWAS) in CSP #572 and benchmarked the predictive value of polygenic risk scores (PRS) constructed from published findings. We combined our results with available summary statistics from several recent GWAS, realizing the …

Hepatic Candidiasis In An Immunocompetent Patient: A Diagnostic Challenge, Zorays Moazzam, Amman Yousaf, Zahid Iqbal, Ahmad Tayyab, Muhammad Hashim Hayat

Medical College Documents

Hepatic candidiasis is a manifestation of disseminated candidiasis, which typically presents in immunocompromised patients. Focal hepatic candidiasis in immunocompetent patients, however, is infrequent/extremely rare. We present the case of an immunocompetent female patient who presented with respiratory distress and right-sided pleural effusion. The pleural fluid tap did not grow anything, and a contrast-enhanced computed tomography (CT) scan revealed a right liver lobe subcapsular collection. CT-guided aspiration and culture resulted in Candida albicans growth. The patient responded to oral fluconazole, and a follow-up CT scan demonstrated resolution of the collection. Although hepatic candidiasis rarely occurs in immunocompetent patients, it should be …

New Psychoactive Substances In Taiwan: The Current Situation And Initiative For Rational Scheduling, Wen-Jing Yu, Linda B. Cottler, Jih-Heng Li

Journal of Food and Drug Analysis

Use of New Psychoactive Substances (NPS) has posed a global threat to public health and the security of the population. As of December 2019, the NPS items identified in total have outnumbered by three to one the controlled substances listed in the 1961 and 1971 UN Drug Conventions. However, most of these NPS have not been scheduled by the United Nations because of their easy modification on the chemical structures to shun control. Currently, the scheduling and control of NPS is mostly at the national level and a rational scheduling of NPS by objective assessments is essential but often lacking. …

Fluorescence Spectroscopy For The Determination Of Reconstitution Time Of An In-Vial Lyophilised Product, Khaled Elkassas, Krishnakumar Chullipalliyalil, Michael Mcauliffe, Sonja Vucen, Abina Crean

Cappa Publications

Lyophilisation is a prominent technique used to create stabilised, dried forms of biopharmaceutical formulations. Reconstitution of lyophilised parenteral formulations is a key step prior to patient administration. The accurate determination of reconstitution time is a necessity to aid formulation development and support product quality control. Traditional methods for quantifying reconstitution time involve the visual identification of the endpoint, which has led to variable values reported across studies. In this work, the use of ultra-violet (UV) excited fluorescence spectroscopy as an alternative to the visual quantification of the reconstitution time was investigated. Spectrographic information was collected via a bespoke setup that …

A Machine Learning Compatible Method For Ordinal Propensity Score Stratification And Matching, Thomas J Greene, Stacia M Desantis, Derek W Brown, Anna V Wilkinson, Michael D Swartz

Faculty, Staff and Student Publications

Although machine learning techniques that estimate propensity scores for observational studies with multivalued treatments have advanced rapidly in recent years, the development of propensity score adjustment techniques has not kept pace. While machine learning propensity models provide numerous benefits, they do not produce a single variable balancing score that can be used for propensity score stratification and matching. This issue motivates the development of a flexible ordinal propensity scoring methodology that does not require parametric assumptions for the propensity model. The proposed method fits a one-parameter power function to the cumulative distribution function (CDF) of the generalized propensity score (GPS) …

Minimally Invasive Transhiatal Esophagectomy, Tyler Grenda, Md, Jules Lin, Andrew C. Chang, Rishindra M. Reddy

Department of Surgery Faculty Papers

While traditionally performed through an open approach, the role of minimally invasive technologies has evolved in its application to esophageal resection. Esophagectomy is associated with significant morbidity, which has led to interest in developing minimally invasive esophagectomy (e.g., laparoscopic/thoracoscopic approaches) to address this issue. As a result, the role of minimally invasive approaches for esophageal resection has evolved, with a growing body of literature describing these techniques. Minimally invasive approaches have been applied to transhiatal esophagectomy, with application of both laparoscopic and robotic-assisted techniques. Although minimally invasive esophagectomy approaches are well-described in the literature for esophageal malignancies, the efficacy of …

Ambulatory and Primary Care Articles

Coronavirus disease 2019 (COVID-19) is a global pandemic where several comorbidities have been shown to have a significant effect on mortality. Patients with diabetes mellitus (DM) have a higher mortality rate than non-DM patients if they get COVID-19. Recent studies have indicated that patients with a history of diabetes can increase the risk of severe acute respiratory syndrome coronavirus 2 infection. Additionally, patients without any history of diabetes can acquire new-onset DM when infected with COVID-19. Thus, there is a need to explore the bidirectional link between these two conditions, confirming the vicious loop between "DM/COVID-19". This narrative review presents …

Robust, Flexible, And Scalable Tests For Hardy-Weinberg Equilibrium Across Diverse Ancestries, Alan M. Kwong, Thomas W. Blackwell, Jonathon Lefaive, Mariza De Andrade, John Barnard, Kathleen C. Barnes, John Blangero

School of Medicine Publications

Traditional Hardy-Weinberg equilibrium (HWE) tests (the χ2 test and the exact test) have long been used as a metric for evaluating genotype quality, as technical artifacts leading to incorrect genotype calls often can be identified as deviations from HWE. However, in datasets comprised of individuals from diverse ancestries, HWE can be violated even without genotyping error, complicating the use of HWE testing to assess genotype data quality. In this manuscript, we present the Robust Unified Test for HWE (RUTH) to test for HWE while accounting for population structure and genotype uncertainty, and evaluate the impact of population heterogeneity and genotype …
