USMLE Performance, Subsequent Standardized Testing, and ABIM Certification Exam Preparation for Internal Medicine Residency Programs: A Narrative Review.

Standardized examinations measure progress throughout medical education. Successful completion of the American Board of Internal Medicine Certification Examination (ABIM-CE) benchmarks completion of internal medicine (IM) residency training. Recent declines in initial ABIM-CE pass rates may prompt residency programs to examine strategies to improve learner performance.

Evaluating Real-World Experience With Maribavir for Treatment of Refractory/Resistant Cytomegalovirus in Renal Transplant Recipients.

Introduction: Maribavir was recently approved by the FDA, expanding treatment options for post-solid-organ transplant refractory/resistant CMV. We sought to describe the post-marketing experience with maribavir at a large academic transplant center.

Methods: This was a retrospective observational study of all renal transplant recipients treated with maribavir for refractory/resistant CMV DNAemia/disease.

Defining the Landscape of Educational Experiences in Transplant Infectious Diseases: A National Survey of Infectious Diseases Fellows in the United States.

Background: Transplant infectious diseases (TID) is a growing area of expertise within infectious diseases (ID), but TID training is not standardized. Previous surveys of fellows identified opportunities to improve TID education resources but did not explore didactic, clinical, and nonclinical experiences comprehensively.

Methods: The American Society of Transplantation ID Community of Practice surveyed adult and pediatric fellows in US-based general ID or dedicated TID training programs to explore their didactic exposure, clinical experiences, and non-direct patient care activities in TID.

Clinical approach to donor-derived infection in solid organ transplant recipients.

Donor-derived infection is an uncommon but potentially devastating complication of solid organ transplantation (SOT). Accurate and timely identification of unexpected infectious disease transmission events has implications not only for the recipient(s) experiencing infection, but also other recipients of organs or tissues from the same donor who may require additional testing or risk mitigation, as well as the broader organ transplant regulatory framework. This narrative review synthesizes data from published reports of symptomatic unexpected donor-derived infections in SOT recipients to provide clinicians with a systematic approach to the evaluation of undifferentiated illnesses that may be of donor origin.

Impact of an ultrasensitive Cytomegalovirus quantitative nucleic acid test on Cytomegalovirus detection and therapy in renal transplant recipients.

Background: Cytomegalovirus (CMV) infection has broad implications for morbidity and mortality in renal transplant recipients (RTR). Routine surveillance for CMV replication with PCR-based quantitative nucleic acid testing (qNAT) assays is standard practice in most transplant centers, but the impact of assay sensitivity on antiviral decision-making and virologic outcomes has not been studied. We investigated the effects of an ultrasensitive CMV qNAT assay on multiple clinical outcomes, including time to detection and duration of CMV DNAemia.

Your Outpatient has Coronavirus Disease 2019: What Are the Treatment Options in the Current Severe Acute Respiratory Syndrome Coronavirus 2 Variant Climate?

Mutations accumulated by novel Severe Acute Respiratory Syndrome Coronavirus 2 Omicron sublineages contribute to evasion of previously effective monoclonal antibodies for treatment or prevention of Coronavirus Disease 2019 (COVID-19). Other authorized or approved antiviral drugs such as nirmatrelvir/ritonavir, remdesivir, and molnupiravir are, however, predicted to maintain activity against these sublineages and are key tools to reduce severe COVID-19 outcomes in vulnerable populations. A stepwise approach may be taken to target the appropriate antiviral drug to the appropriate patient, beginning with identifying whether a patient is at high risk for hospitalization or other complications of COVID-19.

Nucleocapsid Antigenemia in Patients Receiving Anti-CD20 Therapy With Protracted COVID-19.

Immunocompromised patients with prolonged coronavirus disease 2019 symptoms present diagnostic and therapeutic challenges. We measured viral nucleocapsid antigenemia in 3 patients treated with anti-CD20 immunotherapy who acquired severe acute respiratory syndrome coronavirus 2 infection and experienced protracted symptoms. Our results support nucleocapsid antigenemia as a marker of persistent infection and therapeutic response.

A 42-Year-Old Man with Back Pain and Lower Extremity Weakness.

Back Pain and Lower-Extremity WeaknessA 42-year-old man with HIV presented for evaluation of acute-onset back pain and lower-extremity weakness. How do you approach the evaluation, and what is the diagnosis?

Occupational risk factors for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare personnel: A 6-month prospective analysis of the COVID-19 Prevention in Emory Healthcare Personnel (COPE) Study.

Objectives: To determine the incidence of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare personnel (HCP) and to assess occupational risks for SARS-CoV-2 infection.

Design: Prospective cohort of healthcare personnel (HCP) followed for 6 months from May through December 2020.

Setting: Large academic healthcare system including 4 hospitals and affiliated clinics in Atlanta, Georgia.

Durability of mRNA-1273 vaccine-induced antibodies against SARS-CoV-2 variants.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutations may diminish vaccine-induced protective immune responses, particularly as antibody titers wane over time. Here, we assess the effect of SARS-CoV-2 variants B.1.

Clinical characteristics and outcomes of toxoplasmosis among transplant recipients at two US academic medical centers.

Toxoplasma gondii can cause severe opportunistic infection in immunocompromised individuals, but diagnosis is often delayed. We conducted a retrospective review of solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients with toxoplasmosis between 2002 and 2018 at two large US academic transplant centers. Patients were identified by ICD-9 or ICD-10 toxoplasmosis codes, positive Toxoplasma polymerase chain reaction test result, or pathologic diagnosis.

Immune Responses to SARS-CoV-2 in Solid Organ Transplant Recipients.

Purpose Of Review: Coronavirus disease 2019 (COVID-19) is caused by a complex interplay between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) dynamics and host immune responses. Hosts with altered immunity, including solid organ transplant recipients, may be at increased risk of complications and death due to COVID-19. A synthesis of the available data on immune responses to SARS-CoV-2 infection is needed to inform therapeutic and preventative strategies in this special population.

Occupational risk factors for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infection among healthcare personnel: A cross-sectional analysis of subjects enrolled in the COVID-19 Prevention in Emory Healthcare Personnel (COPE) study.

Among 353 healthcare personnel in a longitudinal cohort in 4 hospitals in Atlanta, Georgia (May-June 2020), 23 (6.5%) had severe acute respiratory coronavirus virus 2 (SARS-CoV-2) antibodies. Spending >50% of a typical shift at the bedside (OR, 3.

Safety and Immunogenicity of SARS-CoV-2 mRNA-1273 Vaccine in Older Adults.

Background: Testing of vaccine candidates to prevent infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in an older population is important, since increased incidences of illness and death from coronavirus disease 2019 (Covid-19) have been associated with an older age.

Methods: We conducted a phase 1, dose-escalation, open-label trial of a messenger RNA vaccine, mRNA-1273, which encodes the stabilized prefusion SARS-CoV-2 spike protein (S-2P) in healthy adults. The trial was expanded to include 40 older adults, who were stratified according to age (56 to 70 years or ≥71 years).

Adenovirus causing hepatic abscess formation and unexplained fever in adult liver transplant recipients.

Adenovirus infection is commonly associated with self-limited respiratory and gastrointestinal illnesses. However, infection in immunocompromised individuals, such as transplant recipients, can cause severe life-threatening illness including pneumonitis, hemorrhagic cystitis, nephritis, hepatitis, and enterocolitis. In orthotopic liver transplant recipients, adenovirus viremia can cause hepatitis leading to marked transaminitis, allograft loss, and death.

Contemporary Management Strategies in VAD Infection.

Purpose Of Review: The use of durable ventricular assist devices (VAD) to manage end-stage heart failure is increasing, but infection remains a leading cause of morbidity and mortality among patients with VAD. In this review, we synthesize recent data pertaining to the epidemiology, diagnosis, management, and prevention of VAD infections, discuss transplant considerations in patients with VAD infections, and highlight remaining knowledge gaps. We also present a conceptual framework for treating clinicians to approach these infections that draws on the same principles that guide the treatment of analogous infections that occur in patients without VAD.

Relapsing Uveitis due to Human T-lymphotropic Virus Type 1 in a Patient Living With HIV Diagnosed by Metagenomic Deep Sequencing.

HIV infection can result in vision loss from different causes, including HIV retinopathy and uveitis secondary to other infections, such as toxoplasmosis and viral retinitis. It is imperative to identify any infectious causes of uveitis to successfully treat the condition and prevent further vision loss. Metagenomic deep sequencing (MDS) is an emerging technology that presents an unbiased approach to the evaluation of clinical syndromes, including uveitis, that have not been diagnosed by pathogen-specific testing.
