Precision symptom phenotyping identifies early clinical and proteomic predictors of distinct COVID-19 sequelae.

Background: Post-COVID conditions (PCC) are difficult to characterize, diagnose, predict, and treat due to overlapping symptoms and poorly understood pathology. Identifying inflammatory profiles may improve clinical prognostication and trial endpoints.

Methods: 1,988 SARS-CoV-2 positive U.

Tropical Diseases in Okinawa: Overview and Emerging Infectious Diseases.

Okinawa prefecture is at risk for emerging infectious diseases due to its subtropical climate and its location within the Indo-Pacific region. Understanding the existing vectors and infectious agents contextualizes current threats, guides treatment, and informs prevention, and may be of unique concern in the setting of complex emergencies.

SARS-CoV-2 infection is associated with self-reported post-acute neuropsychological symptoms within six months of follow-up.

Background: Chronic neuropsychological sequelae following SARS-CoV-2 infection, including depression, anxiety, fatigue, and general cognitive difficulties, are a major public health concern. Given the potential impact of long-term neuropsychological impairment, it is important to characterize the frequency and predictors of this post-infection phenotype.

Methods: The Epidemiology, Immunology, and Clinical Characteristics of Emerging Infectious Diseases with Pandemic Potential (EPICC) study is a longitudinal study assessing the impact of SARS-CoV-2 infection in U.

Risk of sexually transmitted infections among U.S. military service members in the setting of HIV pre-exposure prophylaxis use.

Background: The evidence for an increased incidence of sexually transmitted infections (STIs) among patients utilizing HIV pre-exposure prophylaxis (PrEP) has been inconsistent. We assessed the risk of incident STI while on PrEP compared to periods off PrEP among military service members starting PrEP.

Methods: Incidence rates of chlamydia, gonorrhea, syphilis, hepatitis C virus, and HIV were determined among military service members without HIV prescribed daily oral tenofovir disoproxil fumarate and emtricitabine for HIV PrEP from February 1, 2014 through June 10, 2016.

Decreased Self-reported Physical Fitness Following SARS-CoV-2 Infection and the Impact of Vaccine Boosters in a Cohort Study.

Background: The long-term effects of coronavirus disease 2019 (COVID-19) on physical fitness are unclear, and the impact of vaccination on that relationship is uncertain.

Methods: We compared survey responses in a 1-year study of US military service members with (n = 1923) and without (n = 1591) a history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We fit Poisson regression models to estimate the association between history of SARS-CoV-2 infection and fitness impairment, adjusting for time since infection, demographics, and baseline health.

Hashimoto's Encephalopathy with Use of Intravenous Immunoglobulin as First-Line Therapy.

Hashimoto's encephalopathy is an uncommon cause of altered mental status in hospitalized patients and is challenging to diagnose, particularly in the presence of other psychiatric comorbidities. Corticosteroids are the primary treatment. Here, we present a patient with history of post-traumatic stress disorder and prior substance abuse admitted with profound altered mental status and agitation requiring admission to the intensive care unit and mechanical ventilation.

Fatal septic shock due to disseminated coccidioidomycosis: a case series and review of the literature.

Background: Coccidioidomycosis is a fungal infection endemic to the southwestern United States and regions of Latin America. Disseminated disease occurs in < 1% of cases. Septic shock is even rarer, with high mortality despite therapy.

Challenges in Managing Gonorrhea and New Advances in Prevention.

Gonorrhea is the second most common bacterial sexually transmitted infection in the United States. Rates are increasing, and multiple challenges compound management, including worsening antimicrobial resistance. New therapeutics, enhanced screening and partner notification, and treatment through point-of-care testing and expedited partner therapy, as well as primary prevention efforts provide opportunities for success in combating these trends.

Persistent COVID-19 Symptoms at 6 Months After Onset and the Role of Vaccination Before or After SARS-CoV-2 Infection.

Importance: Understanding the factors associated with post-COVID conditions is important for prevention.

Objective: To identify characteristics associated with persistent post-COVID-19 symptoms and to describe post-COVID-19 medical encounters.

Design, Setting, And Participants: This cohort study used data from the Epidemiology, Immunology, and Clinical Characteristics of Emerging Infectious Diseases With Pandemic Potential (EPICC) study implemented in the US military health system (MHS); MHS beneficiaries aged 18 years or older who tested positive for SARS-CoV-2 from February 28, 2020, through December 31, 2021, were analyzed, with 1-year follow-up.

Antigenic cartography of well-characterized human sera shows SARS-CoV-2 neutralization differences based on infection and vaccination history.

The rapid emergence of SARS-CoV-2 variants challenges vaccination strategies. Here, we collected 201 serum samples from persons with a single infection or multiple vaccine exposures, or both. We measured their neutralization titers against 15 natural variants and 7 variants with engineered spike mutations and analyzed antigenic diversity.

An Analysis of SARS-CoV-2 Vaccine Reactogenicity: Variation by Type, Dose, and History, Severity, and Recency of Prior SARS-CoV-2 Infection.

Background: There is limited information on the functional consequences of coronavirus disease 2019 (COVID-19) vaccine side effects. To support patient counseling and public health messaging, we describe the risk and correlates of COVID-19 vaccine side effects sufficient to prevent work or usual activities and/or lead to medical care ("severe" side effects).

Methods: The EPICC study is a longitudinal cohort study of Military Healthcare System beneficiaries including active duty service members, dependents, and retirees.

COVID-19 Patient-Reported Symptoms Using FLU-PRO Plus in a Cohort Study: Associations With Infecting Genotype, Vaccine History, and Return to Health.

Background: Patient-reported outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are an important measure of the full burden of coronavirus disease (COVID). Here, we examine how (1) infecting genotype and COVID-19 vaccination correlate with inFLUenza Patient-Reported Outcome (FLU-PRO) Plus score, including by symptom domains, and (2) FLU-PRO Plus scores predict return to usual activities and health.

Methods: The idemiology, mmunology, and linical haracteristics of pandemic infectious diseases (EPICC) study was implemented to describe the short- and long-term consequences of SARS-CoV-2 infection in a longitudinal, observational cohort.

Understanding "Hybrid Immunity": Comparison and Predictors of Humoral Immune Responses to Severe Acute Respiratory Syndrome Coronavirus 2 Infection (SARS-CoV-2) and Coronavirus Disease 2019 (COVID-19) Vaccines.

Background: Comparison of humoral responses in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinees, those with SARS-CoV-2 infection, or combinations of vaccine/ infection ("hybrid immunity") may clarify predictors of vaccine immunogenicity.

Methods: We studied 2660 US Military Health System beneficiaries with a history of SARS-CoV-2 infection-alone (n = 705), vaccination-alone (n = 932), vaccine-after-infection (n = 869), and vaccine-breakthrough-infection (n = 154). Peak anti-spike-immunoglobulin G (IgG) responses through 183 days were compared, with adjustment for vaccine product, demography, and comorbidities.

SARS-CoV-2 BA.1 variant is neutralized by vaccine booster-elicited serum but evades most convalescent serum and therapeutic antibodies.

The rapid spread of the highly contagious Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) along with its high number of mutations in the spike gene has raised alarms about the effectiveness of current medical countermeasures. To address this concern, we measured the neutralization of the Omicron BA.1 variant pseudovirus by postvaccination serum samples after two and three immunizations with the Pfizer/BioNTech162b2 SARS-CoV-2 mRNA (Pfizer/BNT162b2) vaccine, convalescent serum samples from unvaccinated individuals infected by different variants, and clinical-stage therapeutic antibodies.

Real World Impact of Remdesivir and Dexamethasone on Clinical Outcomes of Severe Coronavirus Disease 2019 in a Community Hospital.

Background: Evidence has emerged showing potential benefit of Remdesivir and dexamethasone in severe coronavirus disease 2019 (COVID-19) but results from large randomized control trials are conflicting. While initial data for dexamethasone indicated a mortality benefit, the impact of Remdesivir was best demonstrated in decreased time to recovery. Despite extensive disease burden throughout the world efficacy data of individual interventions is lacking in part due to extensive concurrent use of confounding investigational therapeutics.

SARS-CoV-2 Omicron neutralization by therapeutic antibodies, convalescent sera, and post-mRNA vaccine booster.

Unlabelled: The rapid spread of the highly contagious Omicron variant of SARS-CoV-2 along with its high number of mutations in the spike gene has raised alarm about the effectiveness of current medical countermeasures. To address this concern, we measured neutralizing antibodies against Omicron in three important settings: (1) post-vaccination sera after two and three immunizations with the Pfizer/BNT162b2 vaccine, (2) convalescent sera from unvaccinated individuals infected by different variants, and (3) clinical-stage therapeutic antibodies. Using a pseudovirus neutralization assay, we found that titers against Omicron were low or undetectable after two immunizations and in most convalescent sera.

Antibiotic resistance, molecular characterizations, and clinical manifestations of Campylobacteriosis at a military medical center in Hawaii from 2012-2016: a retrospective analysis.

Hawaii has one of the highest incidences of Campylobacteriosis in the United States, but there remains little published data on circulating strains or antimicrobial resistance. We characterized 110 clinical Campylobacter isolates (106 C. jejuni, 4 C.

Concurrent Systemic Chemoimmunotherapy and Sofosbuvir-Based Antiviral Treatment in a Hepatitis C Virus-Infected Patient With Diffuse Large B-Cell Lymphoma.

Hepatitis C virus (HCV) infection is associated with the development of non-Hodgkin lymphomas. For aggressive lymphomas, such as diffuse large B-cell lymphoma (DLBCL), treatment of HCV infection is typically deferred in treatment-naive patients until after completion of lymphoma therapy [1, 2]. We report a case of HCV-associated stage IV DLBCL successfully treated concurrently using chemoimmunotherapy and a sofosbuvir-based antiviral regimen.

Natural History of Aerosol Exposure with Marburg Virus in Rhesus Macaques.

Marburg virus causes severe and often lethal viral disease in humans, and there are currently no Food and Drug Administration (FDA) approved medical countermeasures. The sporadic occurrence of Marburg outbreaks does not allow for evaluation of countermeasures in humans, so therapeutic and vaccine candidates can only be approved through the FDA animal rule-a mechanism requiring well-characterized animal models in which efficacy would be evaluated. Here, we describe a natural history study where rhesus macaques were surgically implanted with telemetry devices and central venous catheters prior to aerosol exposure with Marburg-Angola virus, enabling continuous physiologic monitoring and blood sampling without anesthesia.

Immunoproliferative Small Intestinal Disease Associated with Overwhelming Polymicrobial Gastrointestinal Infection with Transformation to Diffuse Large B-cell Lymphoma.

Immunoproliferative small intestinal disease (IPSID) is an extra-nodal B-cell lymphoma most commonly described in the Mediterranean, Africa, and Asia. It is associated with poverty and poor sanitation, and is rarely encountered in developed countries. A 26-year-old previously healthy, Marshallese male was transferred to our facility with a 6-month history of watery diarrhea, weakness, and cachexia refractory to multiple short courses of oral antibiotics.

The potential danger of eating wild lettuce: a brief review of human rat lungworm infection.

Angiostrongylus cantonensis, the causative agent of human rat lungworm disease, is the most common cause of eosinophilic meningitis worldwide and is endemic throughout Asia Pacific. It is acquired through the consumption of infected freshwater mollusks or contaminated produce. Human angiostrongyliasis is usually a self-limited disease presenting with headache and various neurologic sequelae varying from cranial nerve palsies to radiculitis and/or paresthesias.

A unique case of adolescent neuroborreliosis presenting with multiple cranial neuritis and cochlear inflammation on magnetic resonance imaging.

Background: Lyme disease is the most common vector-borne disease in the United States and is caused by infection with the spirochete Borrelia burgdorferi. In children, neuroborreliosis usually presents as peripheral facial nerve palsy and lymphocytic meningitis and only rarely is associated with cranial polyneuritis.

Patient Description: We present a 15-year-old with tinnitus, hearing loss, and facial nerve palsy in the setting of acute, severe right arm pain and a several week history of malaise and headache.
