Division of Infectious Diseases

Recognizing Dr. Diana Florescu, Scientist Laureate

Last week Dr. Diana F. Florescu was honored at a celebration recognizing her recent achievement of being named the UNMC Scientist Laureate, the highest award UNMC bestows upon its researchers.

Dr. Florescu is a Professor in the Division of Infectious Diseases here at UNMC. She came to UNMC first in 2009 as a phenomenal clinician with a focus in treating infections in immunocompromised hosts (solid organ transplant recipients and individuals with malignancy), and over the next 14 years would develop a distinguished research career focused on viral infections in solid organ transplant recipients, including treatment and vaccines. This work has been nationally and internationally recognized with nearly 100 peer-reviewed articles, and in 2020, she was a recipient of the UNMC Distinguished Scientist award, recognizing the most productive researchers at UNMC in the previous 5 years. She did not slow this work during the COVID-19 pandemic, in fact, she escalated her clinical research, leading investigation as a top enrolling site for the Novovax (NVX-CoV2373) COVID-19 vaccine clinical trial, as well as other COVID-19 treatment trials and other non-COVID-19 studies in immunocompromised patients.

In addition to her extraordinary contributions to research and clinical care, Dr. Florescu has served as an invaluable mentor to the UNMC ID Faculty, residents, and APPs in the transplant ID service line. Outside of the hospital, she has been an advocate for her immunocompromised patients and patients experiencing homelessness in Omaha, and combines her love (and talent!) for ballroom dancing with this service, competing in and winning many dance competition fundraisers. UNMC ID is immensely proud of Dr. Florescu and excited to celebrate this recognition with her.

Here are some highlights of her outstanding accomplishments and comments made by a few of her mentors, colleagues, mentees, and friends celebrating her recognition. Congratulations, Dr. Florescu!

Research Digest: Antimicrobial Strategies

Research Digest is a periodic installment that recognizes the world-class clinical research performed right here at UNMC ID. Today, we review two articles covering novel antimicrobial efforts or discoveries that may help us better treat different infectious pathologies. As always, check out the linked full articles for more details.


Dr. Cortes-Penfield, co-author of a recent review of the literature covering the switch between i.v. and oral antibiotics.

In the first article, Dr. Nicholas Cortes-Penfield and co-authors review evidence for the timing and process of switching from i.v. to oral antibiotic treatments during bone or joint infection. The authors explain that, for the past 50+ years, the medical community has been divided on the best time to transition from the standard post-surgical i.v. antibiotic regimen to a more accessible oral strategy, with regional and global differences in accepted standard of care. The team reviewed 8 randomized control trials and multiple retrospective studies and concluded that no data exists to definitively set a minimum i.v. antibiotic duration post-surgery. That said, a growing body of research supports an early switch to oral antibiotics, in most cases, within a few days following surgery. The authors caution, however, that this approach should be tailored for case-specific factors. Read the full article here.


Dr. Jonathan Ryder, 2nd year UNMC ID fellow
Dr. Ryder, a recent co-author of a paper on antiseptic catheter cap strategies.

The second article, co-authored by Dr. Jonathan Ryder, Dr. Daniel Brailita, Dr. Mark Rupp, and Dr. Richard Hankins, along with others from the UNMC community, tests whether additional sterilization of catheter connectors is beneficial in reducing the risk of microbial colonization of catheter equipment. Antiseptic-containing port-protecting caps are routinely used to help limit this possibility. However, the team aimed to determine whether additional manual disinfection with an alcohol wipe was further preventative of microbial colonization (the current standard of care at UNMC). 356 catheter connectors were cultured in this study, 165 in each group, with an additional 26 that did not have an antiseptic cap as a control group. The team found that the vast majority of positive cultures were from the non-antiseptic cap group (15 positive cultures), while both antiseptic cap treatments (with and without manual disinfection) performed similarly, with 1 and 2 positive cultures, respectively. The team concluded that antiseptic caps are an extremely useful tool for preventing bacterial colonization, but additional disinfection strategies (i.e. manual alcohol-based disinfection) do not further decrease the chance of colonization.

Sneak Peak: UNMC Specialty Care Center to Present Work at National Conference

A huge congrats to the Telehealth and Text to Improve Engagement in Care (i2TEC) initiative team, including Lance L. Burwell, LIMHP, PC– behavioral therapist at the UNMC SCC, who will be presenting work at the 2024 National Conference on Social Work and HIV/AIDS between May 22nd and 25th. 

Lance and co-presenters will be detailing progress with the i2TEFC initiative, which is funded by the Health Resources and Services Administration (HRSA) Special Projects of National Significance.  The intervention is meant to be a tool that supports people with HIV in achieving viral suppression and engaging in care.  It consists of 12 video-based counseling sessions delivered by a social worker or mental health professional, who uses motivational interviewing and problem-solving methods to support clients with HIV in addressing mental health, substance use, and other barriers to care engagement.  By delivering services from a telehealth platform, barriers related to HIV stigma and transportation access can be reduced thus allowing more people access to services which address barriers and encourage engagement in care to help people living with HIV achieve and maintain viral suppression. 

This intervention has been implemented at UNMC for one year and has included intervention learning sessions, site visits, and monthly monitoring calls, with the results of this project presented in May at a workshop titled Bridging HIV Care Gaps through Telehealth: An Evidence-Informed Intervention to Support Engagement in Care.

Congrats Lance! If you happen to be attending the conference in May, you don’t want to miss this exciting presentation! If not, we will also recap the highlights here on the UNMC ID blog.

Chief, Division of Infectious Diseases – Position Announcement

Research Digest: Clinical Trials for COVID-19

Research Digest is a periodic installment that recognizes the world-class clinical research performed right here at UNMC ID. Today, we review three articles covering clinical trials that evaluate new drugs for the treatment of COVID-19, using three different approaches. As always, check out the linked full articles for more details.


Diana Florescu, MD, co-author of a recent reanalysis of a phase 3 COVID-19 clinical trial

In the first article, published in the journal Infection and co-authored by the late Dr. Diana Florescu, the authors examine the data from a phase 3 randomized and placebo-controlled trial of the antiviral medication molnupiravir specifically in immunocompromised patients. This medication works by inhibiting the ability of the virus to replicate and infect other cells. The study found a large reduction in hospitalization, death, and adverse events in immunocompromized patients who recieved treatment with molnupiravir, along with enhanced clearance of infectious virus. The authors conclude that, while this study had a small sample size, this evidence suggests that molnupiravir is a safe and efficacious treatment for mild-to-moderate COVID-19 in non-hospitalized immunocompromized patients.


Dr. Andre Kalil, co-author of a recent clinical trial exploring a new type of COVID-19 treatment

The second article, co-authored by Dr. Andre Kalil, takes a different approach by targeting the immune response to SARS-CoV-2 infection instead. Severe COVID-19 pneumonia can cause elevated production of a human protein called IL-33 by the immune system. While meant to enhance immune function, this exaggerated response instead causes excessive damage to the body during severe infection, contributing to the development of Acute Respiratory Distress Syndrome (ARDS). This study examined the efficacy and safety of new drugs aimed at interfering with the IL-33 pathway, among other approaches. While these new medications were not associated with safety concerns, the authors report that there was no improvement in time-to-recovery in patients with severe COVID-19 pneumonia.


Dr. Hewlitt, a member of the ACTT-4 Study Group which investigated this new approach to immunomodulation during COVID-19

The last article, published in The Lancet: Respiratory Medicine also co-authored by Dr. Kalil along with LuAnn Larson, RN, and Dr. Angela Hewlitt, explores the efficacy of adjunct therapy with baricitinib or dexamethasone in addition to a standard COVID-19 medication, remdesivir. Both baricitinib and dexamethasone calm an overactive immune response, though through different means, and have evidence supporting their use during COVID-19. However, a study comparing their efficacy in conjunction with antiviral therapy has not previously been performed. To explore this regimen, the authors conducted a randomized, double-blind, double placebo-controlled trial with patients enrolled at 67 trial sites across the globe. The study found that the addition of baricitinib or dexamethasone to remdesivir resulted in similar rates of mechanical ventilation-free survival by the end of the study period. However, patients administered dexamethasone experienced significantly more adverse events, treatment-related adverse events, and severe or life-threatening adverse events than those taking baricitinib. The authors conclude, “a more individually tailored choice of immunomodulation now appears possible, where side-effect profile, ease of administration, cost, and patient comorbidities can all be considered”.

Congratulations to Dr. Cortés-Penfield

Congratulations to Dr. Nicolás Cortés-Penfield, who was recently invited to join the Open Forum Infectious Diseases editorial advisory board.


Editorial advisory boards are composed of influential individuals in a journal’s field who are tasked with guiding the direction and progress of a journal. This is accomplished in many ways but often involves reviewing potential manuscripts for scientific integrity and rigor before publication. Additionally, members provide input and knowledge to guide the development of a journal and, by extension, the academic field at large.

An invitation to a journal’s editorial advisory board is a recognition of expertise and quality contributions to a field’s scientific literature. Congratulations, Dr. Cortés-Penfield, on an honor well deserved!

Publication Alert: Improving Treatment of COVID-19 in Immunocompromised Individuals

This just in! A new article published last month by Dr. Andre Kalil outlines an effective measure to treat COVID-19 in immunocompromised individuals at elevated risk of serious disease from this infection. See below for a quick digest of the article, and read the full story here.


Why is it essential to research COVID-19 treatment specifically in the immunocompromised population?

Dr. Andre Kalil, author of a new study assessing the efficacy of antiviral medication in immunocompromised COVID-19 patients.

This population is at elevated risk of severe disease and death resulting from infection. This is due to an increased susceptibility to the virus and the reduced efficacy of preventative measures, such as vaccines. Therefore, these patients have been largely excluded from clinical trials centered around COVID-19 for ethical and logistical reasons. This means there are comparatively few evidence-backed medical standards for treating COVID-19 infection in this population, leaving medical professionals with insufficient standardized guidance on which regimens are safe and effective.

How does the study address this gap in evidence-based medicine?

This study focused specifically on immunocompromised COVID-19 patients and retrospectively assessed whether or not they were administered remdesivir, a common COVID-19 treatment, during their hospital stay, calculating all-cause mortality rates for each population. More than 50,000 patients from 48 US states were assessed in this study.

What is remdesivir?

Remdesivir is an anti-viral medication that has been shown to be very effective in reducing death, disease severity (including the need for assisted ventilation), and hospitalization rates among infected individuals. It works by interfering with the ability of the virus to replicate itself and infect other cells.

What did they find?

Graphical abstract from Mozaffari et al.

The authors found that patients who were administered remdesivir had a much lower mortality rate than those who did not receive the medication. This trend was consistent across multiple different SARS-CoV-2 variants, including pre-Delta, Delta, and Omicron viruses. The authors concluded, “Remdesivir, with its established efficacy and safety profile and widespread availability, is an important therapeutic option for treatment of COVID-19 in immunocompromised patients“.

Research Digest: Improving the Practice of ID

Research Digest is a periodic installment that recognizes the world-class clinical research performed right here at UNMC ID. Today, we review three articles covering the efforts to utilize research to improve the way we practice medicine, from optimizing the work environment to making it easier to find the most up-to-date recommendations. As always, check out the linked full articles for more details.


Dr. Hewitt, co-author of an article examining the effect of PPE on providers

The first article, co-authored by our own Dr. Angela Hewitt and Dr. James Lawler of the UNMC Global Center for Health Security, discussed the impact of heat strain and dehydration on healthcare workers who must wear personal protective equipment (PPE) as they care for patients with high-consequence infectious diseases. The authors conducted a literature review of 30 articles that analyzed the effect of PPE on providers and concluded that there is much benefit to be gained from the development of cooler and more comfortable PPE materials. Such developments could slow the rate of dehydration and reduce heat strain on front-line workers caring for those with serious infectious diseases. Read the full details here.


Drs. Broadhurst (left) and Brett-Major (right), co-authors of this study assessing the success of the ISTARI system

The next article, authored by many UNMC faculty members, including Dr. Jana Broadhurst and Dr. David Brett-Major, explored the use of a new generation of cost-effective biocontainment units called ISTARI (Isolation System for Treatment and Agile Response for High-Risk Infections). Designed to provide negative-pressure rooms in low-resource areas and decrease PPE use in the setting of highly infectious diseases, each unit is designed to perform ~20 air exchanges/hour with HEPA filters and multiple access points for providers to perform patient care without entering the unit, decreasing overall PPE usage. While some limitations were noted, providers rated their ability to perform their job roughly equivalent to the standard care scenario. 100% of teams met critical actions for patient management, including intubation, cardioversion, and CPR! This establishes the ISTARI unit as a cost-effective isolation unit, maximizing provider safety in managing patients with highly infectious diseases, particularly in low-resource settings. Read the full story here.


Dr. Cawcutt, co-author of this report on the rapid dissemination of COVID-19 best practices

The last article, co-authored by Dr. Kelly Cawcutt, outlines ways to improve the dissemination of new medical information, such as that which changes rapidly (i.e., COVID-19 best practices). The Structured Team-based Optimal Patient-Centered Care for Virus COVID-19 ICU Collaborative is a 6-month project that trains volunteer interprofessional teams on the Checklist for Early Recognition and Treatment of Acute Illness and Injury approach, a structured and systematic method for delivering evidence-based critical care. The included weekly 1-hour videoconference sessions on high-impact topics, monthly quality improvement coaching sessions, and extensive additional resources for asynchronous learning. The program was well-received by participants and led to the initiation of several quality improvement projects. Read the paper here.
