There were few cohort studies or randomized controlled trials, and there was a distinct lack of pharmacogenetic or pharmacogenomic papers. Most studies were not interventional but instead evaluated susceptibility, and when placed on the continuum of translation, more than 90% of the studies were T1. <b><i>Conclusion:</i></b> This study suggests that the translational value of genetic and genomic research in the MENA region is currently suboptimal. Moving forward requires international cooperation and a collaborative cohort program in order to implement precision medicine in this area of the world.

We describe MAGICAL, a hierarchical Bayesian approach that leverages paired scRNA-seq and scATAC-seq data from different conditions to map disease-associated transcription factors, chromatin sites, and genes as regulatory circuits. By simultaneously modeling signal variation across cells and conditions in both omics data types, MAGICAL achieved high accuracy on circuit inference. We applied MAGICAL to studyStaphylococcus aureussepsis from peripheral blood mononuclear single-cell data that we generated from infected subjects with bloodstream infection and from uninfected controls. MAGICAL identified sepsis-associated regulatory circuits predominantly in CD14 monocytes, known to be activated by bacterial sepsis. We addressed the challenging problem of distinguishing host regulatory circuit responses to methicillin-resistant- (MRSA) and methicillin-suscep...

All isolates from R-SAB patients underwent Pulsed-Field Gel Electrophoresis (PFGE). PFGE-indistinguishable pairs from 40 patients underwent whole genome sequencing (WGS). Acute phase plasma from R-SAB and S-SAB patients was matched 1:1 for age, race, gender, and bacterial genotype and underwent cytokine quantification using 25-analyte multiplex bead array. Results: R-SAB occurred in 69 (9.1%) of the 756 study patients. Of the 69 patients, 30 experienced relapse (43.5%) and 39 reinfection (56.5%). Age, race, hemodialysis dependence, presence of foreign body, MRSA, and persistent bacteremia were individually associated with likelihood of recurrence. Multivariate risk modeling revealed...

The reasons for this disparity are unclear. Methods We evaluated a prospectively ascertained cohort of patients with SAB from 1995 to 2020. Clinical characteristics, bacterial genotypes, and outcome were compared among Black and White patients with SAB. Multivariable logistic regression models were used to determine factors independently associated with the outcomes. Results Among 3068 patients with SAB, 1107 (36%) were Black. Black patients were younger (median, 56 years vs 63 years; P < .001) and had higher rates of diabetes (47.5% vs 34.5%, P < .001), hemodialysis dependence (40.0% vs 7.3%, P < .001), and human immunodeficiency virus (6.4% vs 0.6%, P < .001). Black patients had higher rates of methicillin-resistant S. aureus (49.3% vs 44.9%, P = .020), including the USA300 hypervirulent clone (11.5% vs 8.4%, P = .007). White patients had higher rates of corticosteroid use (22....

The clinical characteristics and outcome determinants of SAB in this population are poorly understood. We undertook a prospective cohort study compared the bacterial genotype and clinical outcomes of SAB among SOT and non-solid organ transplant (non-SOT) recipients. Methods Consecutive patients presenting to our institution with SAB between January 1, 2016 and December 31, 2019 were eligible for study inclusion. Each subject’s initial S. aureus bloodstream isolate was genotyped using spa typing and assigned to clonal complexes using Ridom StaphType software. Results A total of 32 SOT and 634 non-SOT recipients with SAB were included. Bacterial genotype did not differ significantly between SOT and non-SOT recipients (p=0.4855), including the proportion of SAB caused by USA300 (12.5% vs 16.7%, p=0.6339). Ninety-day mortali...

The purpose of this project was to determine if racial disparities exist in patients with S. aureus bacteremia (SAB). Methods Data was used from a prospective cohort of patients with SAB at Duke University Medical Center from 1995-2015. Patients were categorized as African American (AA) or White. Characteristics of interest included discharge disposition, metastatic infection, persistence of SAB, and in-hospital mortality stratified by methicillin-susceptible S. aureus (MSSA) and methicillin-resistant S. aureus (MRSA) infections. Statistical comparisons were performed for binary variables with Fisher’s Exact test and continuous variables with Kruskal-Wallis test. Results Among the 2396 patients with SAB, 1496 (62.4%) were White and 900 (37.6%) were AA. 1241 patients (51.8%) had MSSA bacteremia overall. Whites comp...

Fifty‐five transplant recipients (GNB n = 29; SAB n = 26) and 225 nontransplant recipients (GNB n = 114; SAB n = 111) were included for clinical analysis. Transplant GNB had a significantly lower incidence of septic shock than nontransplant GNB (10.3% vs 30.7%, p = .03). Thirty‐day mortality did not differ significantly between transplant and nontransplant recipients with GNB (10.3% vs 15.8%, p = .57) or SAB (0.0% vs 11.7%, p = .13). Next, transplant patients were matched 1:1 with nontransplant patients for the chemokine and cytokine analysis. Five cytokines and chemokines were significantly lower in transplant GNB vs nontransplant GNB: IL‐2 (median [IQR]: 7.1 pg/ml [7.1, 7.1] vs 32.6 pg/ml [7.1, 88...

Little is known about IE management and outcomes in this population. Methods The National Readmissions Database was used to obtain data between October 2015 and October 2018. Billing codes identified admissions for IE in female patients of reproductive age. Demographic characteristics, comorbidities, and outcomes were compared between patients with maternity-associated and nonmaternity-associated IE and obstetric patients who delivered with and without IE. Weighted regressions were used to examine outcomes in adjusted models. Results We identified 12 602 reproductive-aged female patients with a diagnosis of IE, of which 382 (weighted national estimate, 748) were maternity-associated. Of these cases, 117 (weighted national estimate, 217) occurred during a delivery admission. Compared with patients with nonmaternity-associated IE, maternity-associated infection was associated with younge...

Its impact on delivery outcomes is unknown. In this study, we use a national administrative database to compare outcomes of deliveries complicated by IE to non-IE deliveries. Methods The National Readmissions Database was used to identify discharges between Oct. 2015 and Dec. 2017 for deliveries in patients aged 12 – 55 years with concomitant IE, which were compared to those deliveries without IE. Demographics, comorbidities, and outcomes were obtained. Differences between groups were analyzed using weighted Chi-squared test for categorical variables and weighted linear regression for continuous variables. Weighted multivariate regression models adjusted for demographic, facility, and comorbidity conditions were used to evaluate the association between IE and delivery outcomes. Results We identified 88 individuals with IE complicating their delivery hospitalization, corresponding to a national es...

Risk factors and outcomes associated with HVOM among patients with SAB remain incompletely understood. Methods All adult, hospitalized, non-neutropenic patients with SAB were prospectively enrolled from 1995 to 2015. Additional data was subsequently collected on all patients with HVOM. Diagnosis of HVOM was made either radiographically or microbiologically by culture from the infection site. Patients who underwent lumbar puncture or spinal surgery within 30 days prior to the diagnosis of HVOM were excluded. Results Of 2,475 cases of prospectively enrolled patients with SAB, 90 (3.6%) developed HVOM. The most common site of involvement was the lumbar spine (65.6%). MRI was used in the diagnosis of 90% of patients and although only 28.9% underwent bone biopsy, 88.5% of these bone cultures grew S. aureus. Patients with HVOM were more likely to have c...

Methods We used data from the 2013–2017 Nationwide Readmissions Database (NRD). Hospitalizations associated with IE were identified using diagnosis and procedure codes. The cohort included all patients with IE, stratified by history of solid organ transplant (heart, liver, kidney, lung, intestines, pancreas). Outcomes included 60-day rates of mortality, (extracorporeal membrane oxygenation) ECMO deployment, thromboembolic events, length of stay, and inpatient costs. Regression models, weighted to account for the NRD sample design, were used to model associations between outcomes and transplant history, adjusting for patient age, sex, facility characteristics, comorbid conditions, and potential IE organism. Results A total of 175,682 hospitalizations associated with IE, corr...

We used a large cohort of transplant recipients to assess the impact of IE on outcomes during index transplant hospitalization. Methods We used data from the 2013-2017 Nationwide Readmissions Database (NRD). Hospitalizations associated with solid organ transplantation procedures (heart, liver, kidney, lung, intestines, pancreas) were included. Outcomes included 60-day rates of mortality, ECMO deployment, thromboembolic events, length of stay, and inpatient costs. For data obtained October 2015 and later, rates of graft rejection and graft failure were also measured. Regression models, weighted to account for the NRD sample design, were used to model associations between outcomes and transplant procedure, adjusting for patient age, sex, facility characteristics, comorbid conditions, and organs transplanted.
