Model For End-Stage Liver Disease-Sodium Underestimates 90-Day Mortality Risk In Patients With Acute-On-Chronic Liver Failure, Ruben Hernaez, Yan Liu, Jennifer R Kramer, Abbas Rana, Hashem B El-Serag, Fasiha Kanwal

Faculty, Staff and Students Publications

BACKGROUND & AIMS: It is unclear whether the model for end-stage liver disease-sodium (MELD-Na) score captures the clinical severity of acute-on-chronic liver failure (ACLF). We compared observed 90-day mortality in patients with ACLF with expected mortality based on the calculated MELD-Na and examined the consequences of underestimating clinical severity.

METHODS: We identified patients with ACLF during hospitalization for cirrhosis in 127 VA hospitals between 01/01/2004 and 12/31/2014. We examined MELD-Na scores by ACLF presence and grade. We used actual and observed 90-day mortality to estimate a standardized mortality ratio (SMR) by ACLF presence and grade. We used transplant center-specific median …

External Stoma Diversion: A Palliative Measure For Peristomal Wound Healing In Resource-Limited Settings, Rachel W Davis, Youmna A Sherif, Catherine Anne Morrison

Faculty, Staff and Students Publications

The provision of intestinal stoma care is challenging in austere settings due to limitations in surgical and wound care access as well as the high cost and sparsity of ostomy supplies. As a result, many surgical patients suffer from ostomy-related complications such as peristomal wounds and are unable to find relief for these complications from standard treatments and measures. This article describes the external stoma diversion, a cost-effective palliative surgical procedure that assists in the healing of peristomal wounds in resource-limited settings.

Obesity fosters low-grade inflammation in white adipose tissue (WAT) that may contribute to the insulin resistance that characterizes type 2 diabetes. However, the causal relationship of these events remains unclear. The established dominance of STAT1 function in the immune response suggests an obligate link between inflammation and the comorbidities of obesity. To this end, we sought to determine how STAT1 activity in white adipocytes affects insulin sensitivity. STAT1 expression in WAT inversely correlated with fasting plasma glucose in both obese mice and humans. Metabolomic and gene expression profiling established STAT1 deletion in adipocytes (STAT1a-KO) enhanced mitochondrial function …

Advances in cancer treatments have improved clinical outcomes, leading to an increasing population of cancer survivors. However, this success is associated with high rates of short- and long-term cardiovascular (CV) toxicities. The number and variety of cancer drugs and CV toxicity types make long-term care a complex undertaking. This requires a multidisciplinary approach that includes expertise in oncology, cardiology and other related specialties, and has led to the development of the cardio-oncology subspecialty. This paper aims to provide an overview of the main adverse events, risk assessment and risk mitigation strategies, early diagnosis, medical and complementary strategies for prevention and …

Inferior St-Elevation Myocardial Infarction Presenting When Urgent Primary Percutaneous Coronary Intervention Is Unavailable: Should We Adhere To Current Guidelines?, Yochai Birnbaum, Glenn N Levine, John French, Juan Carlos Kaski, Dan Atar, Mahboob Alam, David Hasdai, Hani Jneid, Barry F Uretsky

Faculty, Staff and Students Publications

The pivotal studies that led to the recommendations for emergent reperfusion therapy for ST-elevation myocardial infarction (STEMI) were conducted for the most part over 25 years ago. At that time, contemporary standard treatments including aspirin, statin, and even anticoagulation were not commonly used. The 2013 American College of Cardiology Foundation (ACCF)/American Heart Association (AHA) guidelines and the 2017 European Society of Cardiology guidelines give a class I recommendation (with the level of evidence A) for primary percutaneous coronary intervention (pPCI) in patients with STEMI and ischemic symptoms of less than 12 h. However, if the patient presents to a hospital …

Informing Strategy To Ensure Detection: Perceptions Of Coronavirus Testing In A Southeastern U.S. Urban Homeless Population, Colleen Bell, Theodore Bosi, Barbara L. Gracious

HCA Healthcare Journal of Medicine

Introduction: Attitudes of those in the homeless population toward testing, particularly during a pandemic, are critical to understand, so that they and their communities may be safely triaged and protected. Homeless persons are more likely to be exposed during viral epidemics, and have greater vulnerability for more severe viral illness, due to greater medical comorbidities. The literature reflects a dearth of published papers describing the perceptions, interest, and motivations of homeless people to seek or receive viral testing, despite their status as a high-risk population.

Methods: A quality improvement project consisting of a cross-sectional survey took place at 8 SARS-CoV-2 …

Innovative Conservation Of Inhaled Medication Devices During The Covid-19 Pandemic Through A Canister Reassignment Process, Mandelin K. Cooper, L. Hayley Burgess, Karla Miller, Theresa Baltz, Julia Moody, Elizabeth Wiggins, Jeffrey Guy

HCA Healthcare Journal of Medicine

Background: The ideal practice for patients requiring metered-dose inhalers (MDI) with coronavirus disease 2019 (COVID-19) is to use patient specific MDIs. However, this practice may not be possible during a time of increased usage throughout the country and limited availability of the medication. Nebulized medications are a concern due to the potential for aerosolized virus and increased exposure for health care workers. An alternative program of canister reassignment is proposed to address concerns for infection prevention, cross-contamination of MDI canisters and the shortage of MDI’s due to the COVID-19 pandemic.

Methods: A comprehensive MDI canister reassignment process was developed for …

Extracorporeal Membrane Oxygenation For Covid-19 Treatment In A Community Hospital, Daniel I. Loube, Kashif Z. Hassan, Sang H. Lee

HCA Healthcare Journal of Medicine

Coronavirus disease 2019 (COVID-19) may result in severe acute respiratory disease syndrome (ARDS) and death. For COVID-19 patients failing mechanical ventilation, extra corporeal membrane oxygenation (ECMO) has been used with varying efficacy in academic medical centers and quaternary referral centers. We report the successful use of veno-venous (VV) ECMO to treat refractory ARDS due to COVID-19 in a community hospital setting with a survival to discharge rate of 71% over a 3 month period. In a community hospital with adequate resources, VV ECMO can be an effective rescue therapy for selected COVID-19 patients who fail all other available treatments.

The Public Health Demand For Revoking Non-Medical Exemptions To Compulsory Vaccination Statutes, Emma Tomsick

Journal of Law and Health

In 2019, the United States saw the single largest outbreak of measles in recent history. The measles crisis has prompted state legislative bodies to face a seemingly impossible dilemma: eliminate both religious and philosophical exemptions to mandatory school vaccination statutes or sit by idly and allow measles to continue to run its course. As of June 2019, five states have neither religious nor philosophical exemptions to their mandatory vaccination statutes. This Note argues that states should remove all religious and philosophical exemptions to compulsory vaccination statutes. The 2019 measles outbreak demonstrates that the anti-vaccination movement poses a legitimate risk to …

Madhi, Cheryl Cohen, Syed Asad Ali, Sudha Basne, Quique Bassat, W Abdullah Brooks, Malinee Chittaganpitch

Department of Paediatrics and Child Health

Background: Human metapneumovirus is a common virus associated with acute lower respiratory infections (ALRIs) in children. No global burden estimates are available for ALRIs associated with human metapneumovirus in children, and no licensed vaccines or drugs exist for human metapneumovirus infections. We aimed to estimate the age-stratified human metapneumovirus-associated ALRI global incidence, hospital admissions, and mortality burden in children younger than 5 years.
Methods: We estimated the global burden of human metapneumovirus-associated ALRIs in children younger than 5 years from a systematic review of 119 studies published between Jan 1, 2001, and Dec 31, 2019, and a further 40 high …

Differences In Gynecologic Tumor Development In Amhr2-Cre Mice With Krasg12d Or Krasg12v Mutations, Eucharist H S Kun, Yvonne T M Tsang, Sophia Lin, Sophia Pan, Tejas Medapalli, Anais Malpica, Joanne S Richards, David M Gershenson, Kwong-Kwok Wong

Faculty, Staff and Students Publications

How different KRAS variants impact tumor initiation and progression in vivo has not been thoroughly examined. We hypothesize that the ability of either KRASG12D or KRASG12V mutations to initiate tumor formation is context dependent. Amhr2-Cre mice express Cre recombinase in tissues that develop into the fallopian tubes, uterus, and ovaries. We used these mice to conditionally express either the KRASG12V/+ or KRASG12D/+ mutation. Mice with the genotype Amhr2-Cre Pten(fl/fl) KrasG12D/+(G12D mice) had abnormal follicle structures and developed low-grade serous ovarian carcinomas with 100% penetrance within 18 weeks. In contrast, mice with …
