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: New Findings on 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 new developments regarding COVID-19. As always, check out the linked full articles for more details.


Dr. Fadul, senior author on a publication exploring the COVID-19 vaccination status and opinions of Sudanese Americans.

In the first article, authored by graduating UNMC medical student Jonathan Freese, Dr. Nada Fadul, and others, the state of vaccine hesitancy and uptake was characterized among Sudanese Americans. Community-level inquiries on vaccine practices are crucial as the risk of infection is not constant across the population, and certain groups, including Sudanese Americans and other immigrant and refugee communities, have historically higher risk of COVID-19 exposure. With the help of community leaders, this study surveyed over 100 individuals. Vaccine hesitancy, when present, was found to be driven primarily by fears that it had not been studied enough. However, the authors found that the rate of COVID-19 vaccination exceeded the national average (93% vs 78% for the American public), a metric that covaried with educational attainment and belief in vaccine efficacy. Find the full article here.


The second article, co-authored by Dr. Andre Kalil, is an invited commentary that calls for a change in the way COVID-19 investigational drug trials are controlled. The authors point out that while some COVID-19 investigational compounds have been reported to cause cardiac complications, COVID-19 infection itself is known to cause many of these same complications. Without a sound control group and a carefully designed study, it is all too easy to falsely attribute adverse cardiac events to the drug being used to treat the infection when they may be the result of the infectious pathology itself. Randomized controlled trials have a long history of sound scientific and medical success in both ID and cardiology, but this hinges on meticulously designed studies. In short, an adverse event seen in those given the experimental treatment may be a sign of clinical efficacy if the rate that it is observed is actually higher in the untreated control group. However, if this factor is not examined in the control group, it would appear falsely to be caused by the treatment instead. Read the full commentary here.


Dr. Andre Kalil, co-author on two recent publications examining COVID-19 treatments and their risks.

In the last article, also co-authored by Dr. Kalil, the risk of immunomodulatory medications in COVID-19 was assessed, specifically in immunocompromised patients at higher risk of side effects from these treatments. Several immunomodulators have been shown to be beneficial in the treatment of COVID-19, as they can help restrict an overactive immune response and prevent collateral damage to the body during infection. However, by inhibiting certain aspects of the immune system, these drugs may also have the potential to increase the risk of secondary infections in those with an already compromised immune system. This study examined the existing literature, conducting a meta-analysis to determine whether evidence of outsized risk of these medications existed within immunocompromised populations, finding no statistically significant difference between patients randomized to immunomodulators vs control in terms of mortality or secondary infections. Read the full details of the analysis, including more detailed conclusions and considerations, here.

UNMC ID Recognizes STI Awareness Week

This week is Sexually Transmitted Infection (STI) Awareness Week, a week set aside to educate and raise awareness about sexually transmitted infections, or STIs, and how they impact our lives. It is also a time to work towards reducing STI-related stigma, fear, and discrimination and a time to ensure people have the tools and knowledge for prevention, testing, and treatment.

The CDC estimates that about 20 percent of the U.S. population – one in five people – had an STI on any given day in 2018. Left undiagnosed or untreated, many STIs can lead to serious health problems and permanent damage, both in the short and long term. ID and primary care providers are on the frontlines of this crisis, and we would like to take this opportunity to recognize their work in identifying, diagnosing, and treating STIs- as early diagnosis and treatment is key to preventing associated complications.

For more information and resources about STIs, see the CDC’s page on general resources for STI Awareness Week 2024 here, including resources designed for clinicians to help improve communication about and treatment of STIs.

Dr. Rupp to Receive Bartee Advocacy of Science Award

Dr. Mark Rupp, chief of the UNMC Division of Infectious Diseases, is set to be awarded the Bartee Advocacy of Science Award in recognition of his exceptional community engagement as a scientist.

Support Dr. Rupp and UNMC ID by attending the awards ceremony at 12pm on March 26th (Yanney Conference Room, Fred & Pamela Buffett Cancer Center)


We are proud to share that our division’s chief, Dr. Rupp, will be awarded the Bartee Advocacy of Science Award tomorrow at noon! The Bartee Advocacy of Science Award is given to a UNMC scientist who exemplifies and lives out a commitment to community engagement. Dr. Rupp was chosen for the inaugural honor by a process led by Chris Kratochvil, Bob Bartee’s successor as vice chancellor of external relations for UNMC.

First published in a UNMC Newsroom post, Dr. Rupp commented on the award earlier this month:

“I am very pleased and incredibly honored to receive the inaugural Bartee Family Award for promotion of science literacy and advocacy. I have long respected and admired Bob for his incredible contributions to UNMC over the course of his career – which makes this award even more meaningful to me. I believe the amplification of scientific misinformation and disinformation via social media is a pressing challenge and the promotion of scientific literacy may be one of our best strategies to preserve public health. I am honored to share the stage with Mary Woolley, the president of Research America, and I look forward to her presentation.”

Bartee, the award’s namesake, has commented in return:

“During the COVID-19 pandemic, many medical center professionals distinguished themselves in providing accurate and timely scientific information to the public. Dr. Rupp stood out among an impressive group for his willingness to engage the media, elected officials and members of the public, at times almost daily, to provide a calm and reasoned voice among a cacophony of misinformation. I am pleased and honored that he is the first recipient of the Bartee Award.”


Please join us in celebrating Dr. Rupp’s huge (and well-deserved) achievement by attending the inaugural Bob and Helen Bartee and Family Advocacy of Science Lectureship; info below:

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!
