Persons with HIV (PWH) represent a socially and medically vulnerable population who often depend on public resources. We examined voter registration among PWH in North Carolina. Sixty-four percent were registered to vote. Registration was lower among PWH who were young, Hispanic, publicly insured or uninsured, and who had poor HIV health status.We report 2 cases for whom Xpert MTB/RIF falsely signaled rifampicin-resistant tuberculosis, based on unusually low cycle threshold and 3 of 5 probes missing. Other mycobacterial tests were negative. Further optimization of the Xpert MTB/RIF algorithm is warranted.

Grading of Recommendations Assessment, Development, and Evaluation (GRADE) is a systematic approach to grading strength of recommendation (SOR) and quality of evidence (QOE) for guideline recommendations. We aimed to assess the relationship between SOR and QOE in current Infectious Diseases Society of America (IDSA) guidelines.

In this cross-sectional analysis, we analyzed the frequency of SOR-QOE pairings, including discordance (defined as strong SOR based on expert opinion, very low, or low QOE) for GRADEd recommendations in IDSA guidelines published since 2010. Data for each recommendation were extracted on SOR, QOE, the domain of disease management (one or more of diagnosis, treatment, prevention, and other categories), and relevance to drug or nondrug treatment.

Seventeen eligible guidelines provided 1042 unique GRADEd recommendations (n = 237, 711, 76, and 73 pertaining to diagnosis, treatment, prevention, and other domains, respectively; n = 574 and 137 pertaining to drug and nondrug treatment). f disease management.

Manganese (Mn

has been shown to promote type I interferon (IFN) production and activate the cyclic GMP-AMP synthase (cGAS)/Stimulator of Interferon Genes (STING) signaling pathway, suggesting that Mn

could be used as an adjuvant for vaccination.

In present study, the effects of Mn

on vaccination against hepatitis B virus (HBV) were evaluated. We treated mouse hepatocytes and kuppfer cells with Mn

with or without adeno-associated virus (AAV)-HBV infection. Expression of IFN-α and IFN-β and activation of TBK1 and IRF3 were monitored. Wild-type and STING

mice were treated with Mn

and then infected with AAV-HBV. Serum levels of HBV surface antigen (HBsAg), alanine aminotransferase (ALT) activity, IFN-α, and IFN-β were detected. Lymphocyte infiltration in the liver was evaluated. HBsAg-Tg mice were vaccinated with Mn

and HBsAg. learn more The serum levels of HBsAg antibody, alanine transaminase activity, and IFN-β were monitored after vaccination.

Mn

promoted IFN-α and IFN-β production in mouse hepatocytes and kuppfer cells. Mn

failed to promote IFN-α and IFN-β production in kuppfer cells deficient in STING. Mn

promoted activation/phosphorylation of TBK1 and IRF3 during AAV-HBV infection. Mn

decreased serum levels of HBsAG, increased serum levels of alanine aminotransferase (ALT), IFN-α and IFN-β, and enhanced lymphocyte infiltration and the percentage of IFN-γ-producing CD8

T cells in the liver of AAV-HBV-infected mice. In contrast, Mn

treatment did not affect serum levels of HBsAG, ALT, IFN-α, or IFN-β in STING-deficient mice.

Mn



promoted HBsAG antibody, ALT, and IFN-β production after HBsAG immunization. Mn

promoted type I IFN production in AAV-HBV infection and HBsAG immunization and could be used as an adjuvant for vaccination.

Mn2 + promoted HBsAG antibody, ALT, and IFN-β production after HBsAG immunization. Mn2+ promoted type I IFN production in AAV-HBV infection and HBsAG immunization and could be used as an adjuvant for vaccination.

Outpatient coronavirus disease 2019 (COVID-19) has been insufficiently characterized. To determine the progression of disease and determinants of hospitalization, we conducted a prospective cohort study.

Outpatient adults with positive reverse transcription polymerase chain reaction results for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were recruited by phone between April 21 and July 23, 2020, after receiving outpatient or emergency department testing within a large health network in Maryland, United States. Symptoms were collected by participants on days 0, 3, 7, 14, 21, and 28, and portable pulse oximeter oxygen saturation (SaO

), heart rate, and temperature were collected for 15 consecutive days. Baseline demographics, comorbid conditions, and vital signs were evaluated for risk of subsequent hospitalization using negative binomial and logistic regression.

Among 118 SARS-CoV-2-infected outpatients, the median age (interquartile range [IQR]) was 56.0 (50.0-63.0) years, and 50 (42.4%) were male. Among individuals in the first week of illness (n = 61), the most common symptoms included weakness/fatigue (65.7%), cough (58.8%), headache (45.6%), chills (38.2%), and anosmia (27.9%). Participants returned to their usual health a median (IQR) of 20 (13-38) days from symptom onset, and 66.0% of respondents were at their usual health during the fourth week of illness. Over 28 days, 10.9% presented to the emergency department and 7.6% required hospitalization. The area under the receiver operating characteristics curve for the initial home SaO

for predicting subsequent hospitalization was 0.86 (95% CI, 0.73-0.99).

Symptoms often persisted but uncommonly progressed to hospitalization among outpatients with COVID-19. Home SaO

may be a helpful tool to stratify risk of hospitalization.

The majority of hepatitis C virus (HCV) infections are found in low- and middle-income countries, which harbor many region-specific HCV subtypes. Nevertheless, direct-acting antiviral (DAA) trials have almost exclusively been conducted in high-income countries, where mainly epidemically spread HCV subtypes are present. Recently, several studies have demonstrated suboptimal DAA efficacy for certain nonepidemic subtypes, which could hamper global HCV elimination. Therefore, we aimed to evaluate DAA efficacy in patients treated for a nonepidemic HCV genotype infection in the Netherlands.

We performed a nationwide retrospective study including patients treated with interferon-free DAAs for an HCV genotype other than 1a/1b/2a/2b/3a/4a/4d. The genotype was determined by NS5B region phylogenetic analysis. The primary end point was SVR-12. If stored samples were available, NS5A and NS5B sequences were obtained for resistance-associated substitutions (RAS) evaluation.

We included 160 patients, mainly infected wiAlongside earlier results, our results indicate that a remaining challenge for global HCV elimination is confirming and monitoring DAA efficacy in nonepidemic genotypes.

The interdependencies of viral replication and the host immune response in patients with coronavirus disease 2019 (COVID-19) remain to be defined. We investigated the viral determinants of antibody response, the predictors of nonseroconversion, and the role of antibodies on viral dynamics.

This was a prospective study in patients hospitalized with COVID-19 that was microbiologically confirmed by real-time polymerase chain reaction (RT-PCR). Serial nasopharyngeal and oropharyngeal swabs and plasma samples were obtained for measuring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA and antibodies (total and S-IgG/N-IgG), respectively.

Of 132 patients included, 99 (75%) showed positive antibody titers after a median (Q1-Q3) of 11 (8-14) days. The median (Q1-Q3) follow-up was 74.5 (63.0-87.0) days. In an adjusted linear regression model, time to seropositivity was inversely associated with peak log SARS-CoV-2 viral load (

= .009) and positively with time to viral clearance (

= .004). Adjnce. COVID-19 patients who do not seroconvert exhibit a differential virological and clinical profile.

endocarditis is a rare, sometimes fatal complication of candidemia. Past investigations of this condition are limited by small sample sizes. We used the Vizient clinical database to report on characteristics of patients with

endocarditis and to examine risk factors for in-hospital mortality.

This was a multicenter, retrospective cohort study of 703 inpatients admitted to 179 US hospitals between October 2015 and April 2019. We reviewed demographic, diagnostic, medication administration, and procedural data from each patient's initial encounter. Univariate and multivariate logistic regression analyses were used to identify predictors of in-hospital mortality.

Of 703 patients, 114 (16.2%) died during the index encounter. One hundred fifty-eight (22.5%) underwent an intervention on a cardiac valve. On multivariate analysis, acute and subacute liver failure was the strongest predictor of death (odds ratio [OR], 9.2; 95% confidence interval [CI], 4.8 -17.7). Female sex (OR, 1.9; 95% CI, 1.2-3.0), transfer from an outside medical facility (OR, 1.8; 95% CI, 1.1-2.8), aortic valve pathology (OR, 2.7; 95% CI, 1.5-4.9), hemodialysis (OR, 2.1; 95% CI, 1.1-4.0), cerebrovascular disease (OR, 2.2; 95% CI, 1.2-3.8), neutropenia (OR, 2.5; 95% CI, 1.3-4.8), and alcohol abuse (OR, 2.9; 95% CI, 1.3-6.7) were also associated with death on adjusted analysis, whereas opiate abuse was associated with a lower odds of death (OR, 0.5; 95% CI, 0.2-0.9).

We found that the inpatient mortality rate was 16.2% among patients with

endocarditis. Acute and subacute liver failure was associated with a high risk of death, whereas opiate abuse was associated with a lower risk of death.

We found that the inpatient mortality rate was 16.2% among patients with Candida endocarditis. Acute and subacute liver failure was associated with a high risk of death, whereas opiate abuse was associated with a lower risk of death.In this study, we report the history of a 40-year-old man with a primary cerebral abscess caused by Nocardia abscessus that led to the discovery of autoimmune pulmonary alveolar lipoproteinosis (anti-granulocyte-macrophage colony-stimulating factor [GM-CSF] autoantibodies). Anti-GM-CSF autoantibodies promote immunodeficiency and should be monitored to prevent opportunistic and disseminated infections and to diagnose asymptomatic pulmonary alveolar lipoproteinosis.

Anterior cruciate ligament (ACL) injuries most commonly occur after a perturbation. Prophylactic knee braces (PKBs) are off-the-shelf braces designed to prevent and reduce the severity of knee injuries during sports, yet their effectiveness has been debated.

To identify differences in ACL agonist and antagonist muscle forces, during braced and unbraced conditions, while walking with the application of unexpected perturbations.

Controlled laboratory study.

A total of 20 recreational athletes were perturbed during walking at a speed of 1.1 m/s, and motion analysis data were used to create patient-specific musculoskeletal models. Static optimization was performed to calculate the lower-limb muscle forces. Statistical parametric mapping was used to compare muscle forces between the braced and unbraced conditions during the stance phase of the perturbed cycle.

The brace reduced muscle forces in the quadriceps (QUADS), gastrocnemius (GAS), and soleus (SOL) but not in the hamstrings. The peak QUADS muscle force was significantly lower with the brace versus without at 49% to 60% of the stance phase (28.
