BACKGROUND: Previous studies demonstrated the efficacy of a rifampicin-based regimen in the treatment of acute staphylococcal periprosthetic joint infections (PJIs) treated with surgical debridement. However, evidence is lacking to support the use of rifampicin in cases where the implant is exchanged during revision.
METHODS: We included all consecutive cases of staphylococcal PJIs treated from January 2013 to December 2018 with revision surgery in this international, retrospective, multicenter observational cohort study. PJI was defined according to the European Bone and Joint Infection Society diagnostic criteria. A relapse or reinfection during follow-up, the need for antibiotic suppressive therapy, the need for implant …

This case report examines a previously immunocompetent male that was treated with a prolonged course of corticosteroids for COVID pneumonia. He then returned with worsening headaches followed by flaccid paralysis of extremities due to cerebral and spinal cord abscesses secondary to Nocardia farcinica. A review of the literature on the mechanism of immunosuppression with COVID infection and corticosteroids is provided.

Importance: Obesity, diabetes, and hypertension are common comorbidities in patients with severe COVID-19, yet little is known about the risk of acute respiratory distress syndrome (ARDS) or death in patients with COVID-19 and metabolic syndrome.
Objective: To determine whether metabolic syndrome is associated with an increased risk of ARDS and death from COVID-19.
Design, setting, and participants: This multicenter cohort study used data from the Society of Critical Care Medicine Discovery Viral Respiratory Illness Universal Study collected from 181 hospitals across 26 countries from February 15, 2020, to February 18, 2021. Outcomes were compared between patients with metabolic syndrome (defined …

Burkholderia pseudomallei is an aerobic, motile, non-spore-forming gram-negative bacillus found in tropical endemic environments that causes the disease melioidosis. Melioidosis displays a diversity of clinical presentations ranging from septic shock to chronic latent infection, often with characteristic abscesses in multiple organs. Melioidosis is an opportunistic infection, with risk factors, including diabetes, alcohol use, chronic lung disease, and chronic renal disease, and these risk factors increase the severity of disease (Wiersinga et al., 2006) [1]. In this case report, we illustrate a case of a 32 year old man with several risk factors and recent travel to an endemic region presenting …

Rothia mucilaginosa is increasingly recognized as an emerging pathogen associated with endocarditis. It has mostly been reported a causative agent for prosthetic valve endocarditis. The previously reported cases of native valve endocarditis caused by this organism only required medical treatment with no surgical intervention. We report a case of R. mucilaginosa native valve endocarditis complicated by abscess formation requiring surgical intervention and review the literature of native valve endocarditis caused by this organism.

INTRODUCTION: During the early months of the COVID-19 pandemic, mortality associated with the disease declined in the United States. The standard of care for pharmacological interventions evolved during this period as new and repurposed treatments were used alone and in combination. Though these medications have been studied individually, data are limited regarding the relative impact of different medication combinations. The objectives of this study were to evaluate the association of COVID-19-related mortality and observed medication combinations and to determine whether changes in medication-related practice patterns and measured patient characteristics, alone, explain the decline in mortality seen early in the COVID-19 …

A 59-year-old woman with a status of post–renal transplant 7 years prior for autosomal dominant polycystic kidney disease on tacrolimus and mycophenolate mofetil presented with subacute left knee and right wrist pain. She received local steroid injections to both areas as an outpatient without improvement in her symptoms. She had recently traveled to India, her home country, to visit relatives. Aspiration of the knee revealed 4+ acid fast bacilli on smear, and she was taken for surgical debridement. She was started on empiric antibiotics for presumed infection with rapidly growing mycobacteria. Her course was complicated by acute onset abdominal pain …

Background. Infectious diseases seem to be an important and independent risk factor for renal failure, but the underlying mechanism of renal involvement during some kinds of infectious diseases is still unclear, even if the literature data report immunomediated and/or autoimmune mechanisms to explain the pathogenic relationship between the two diseases. In paediatric patients, Chlamydia pneumoniae is a rare cause of renal complications and it may manifest in several ways, mainly involving the respiratory system, even if also renal and glomerulalr complications, have been described. Case Diagnosis/Treatment. Herein we report a case of a 3-year-old child who developed an acute glomerulonephritis …

Propensity for developing coronary heart disease (CHD) is linked with Framingham-defined cardiovascular risk factors and elevated inflammatory biomarkers. Cardiovascular risk and inflammatory biomarkers were evaluated in ARIES, a Phase IIIb/IV clinical trial in which 515 antiretroviral-naive HIV-infected subjects initially received abacavir/lamivudine + atazanavir/ritonavir for 36 weeks. Subjects who were virologically suppressed by week 30 were randomized 1:1 at week 36 to either maintain or discontinue ritonavir for an additional 108 weeks. Framingham 10-year CHD risk scores (FRS) and risk category of

Background. We report health-related QoL (HRQoL) from GRACE (Gender, Race, And Clinical Experience) study by sex and race over 48 weeks. Methods. 429 treatment-experienced adults (HIV-1 RNA ≥ 1000 copies/mL) received darunavir/ritonavir 600/100 mg twice daily plus an appropriate background regimen. QoL was measured by the Functional Assessment of HIV Infection (FAHI) questionnaire. Results. 67% women and 77% men, including 67.4% black, 76.0% Hispanic, and 73.8% white patients, completed the trial. Baseline total FAHI scores were similar between sexes and races. Total FAHI of the entire population improved by Week 4 (P < .05); near-maximum changes obtained by Week 12 were maintained through Week 48. Women and black patients demonstrated larger improvements in total FAHI versus men, and Hispanic and white patients, respectively. Conclusion. HRQoL improved in all sex and racial/ethnic groups. Sex-based and race-based differences in improvements in FAHI subscales may provide insight into subtle differences of HIV-1 and treatment on HRQoL in different populations.

BACKGROUND: Women, particularly women of color, remain underrepresented in antiretroviral (ARV) clinical trials. To evaluate sex-based differences in darunavir/ritonavir-based therapy, the Gender, Race And Clinical Experience (GRACE) study was designed to enroll and retain a high proportion of women representative of the racial/ethnic demographics of women with HIV/AIDS in the United States. The recruitment and retention strategies used in GRACE are described in this article.
METHODS: Recruitment and retention strategies targeting women included selecting study sites that focused on women, involving community consultants, site-specific enrollment plans, access to other ARV drugs, study branding, site and patient toolkits, targeted public relations, …

Botulinum neurotoxin (BoNT) potently inhibits cholinergic signaling at the neuromuscular junction. The ideal countermeasures for BoNT exposure are monoclonal antibodies or BoNT antisera, which form BoNT-containing immune complexes that are rapidly cleared from the general circulation. Clearance of opsonized toxins may involve complement receptor-mediated immunoadherence to red blood cells (RBC) in primates or to platelets in rodents. Methods of enhancing immunoadherence of BoNT-specific antibodies may increase their potency in vivo. We designed a novel fusion protein (FP) to link biotinylated molecules to glycophorin A (GPA) on the RBC surface. The FP consists of an scFv specific for murine GPA fused …

A novel combination of three codon inserts in the pol coding region of HIV-1 RNA was identified in a highly antiretroviral experienced study subject with HIV-1 infection. A one codon insert was observed in the protease region between codon 40 and 41 simultaneously with a two codon insert present in the reverse transcriptase region at codon 69.
