<b>Objective:</b> Type 2 diabetes mellitus (T2DM) is an important risk factor for the progression of metabolic liver disease to advanced fibrosis. Here, we provide an estimate of the prevalence of steatosis and fibrosis in US adults with T2DM based on transient elastography (TE) and identify factors associated with these conditions. <p><b>Research Design and Methods: </b>This is a cross-sectional study of US adults with T2DM participating in the 2017-2018 cycle of the National Health and Nutrition Examination Survey who were evaluated by TE. Hepatic steatosis and fibrosis were diagnosed by the median value of Controlled Attenuation Parameter (CAP) and Liver Stiffness Measurement (LSM), respectively.</p> <p><b>Results:</b> Among the 825 patients with reliable TE exams, 484 (53.7%) were assessed using the M probe and 341 (46.3%) using the XL probe. Liver steatosis (CAP≥274 dB/m), advanced fibrosis (LSM≥9.7 Kpa) and cirrhosis (LSM≥13.6 Kpa) were present in 73.8% (95% CI 68.5%-78.5%), 15.4% (95% CI 12.2%-19.0%) and 7.7% (95% CI 4.8%-11.9%) of patients, respectively. Mean age of patients with advanced fibrosis and cirrhosis was 63.7 ± 2.2 years and 57.8 ± 1.6 years, respectively. In the multivariable logistic regression model, body mass index (BMI), non-African American ethnicity and alanine aminotransferase levels were independent predictors of steatosis, while BMI, non-African American ethnicity, aspartate aminotransferase and gamma-glutamyltranspeptidase levels were independent predictors of advanced fibrosis.</p> <p><b>Conclusions:</b> Prevalence of both liver steatosis and fibrosis are high in patients with T2DM from the US and obesity is a major risk factor. Our results support the screening of these conditions among diabetic patients.</p>

Background In the midst of the coronavirus disease pandemic, emerging clinical data across the world has equipped frontline health care workers, policy makers, and researchers to better understand and combat the illness. Objective The aim of this study is to report the correlation of clinical and laboratory parameters with patients requiring mechanical ventilation and the mortality in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods We did a review of patients with SARS-CoV-2 confirmed infection admitted and managed by our institution during the last month. Patients were grouped into intubated and nonintubated, and subgrouped to alive and deceased. A comprehensive analysis using the following parameters were performed: age, sex, ethnicity, BMI, comorbidities, inflammatory markers, laboratory values, cardiac and renal function, electrocardiogram (EKG), chest x-ray findings, temperature, treatment groups, and hospital-acquired patients with SARS-CoV-2. Results A total of 184 patients were included in our study with ages ranging from 28-97 years (mean 64.72 years) and including 73 females (39.67%) and 111 males (60.33%) with a mean BMI of 29.10. We had 114 African Americans (61.96%), 58 Hispanics (31.52%), 11 Asians (5.98%), and 1 Caucasian (0.54%), with a mean of 1.70 comorbidities. Overall, the mortality rate was 17.39% (n=32), 16.30% (n=30) of our patients required mechanical ventilation, and 11.41% (n=21) had hospital-acquired SARS-CoV-2 infection. Pertinent and statistically significant results were found in the intubated versus nonintubated patients with confirmed SARS-CoV-2 for the following parameters: age (P=.01), BMI (P=.07), African American ethnicity (P<.001), Hispanic ethnicity (P=.02), diabetes mellitus (P=.001), creatinine (P=.29), blood urea nitrogen (BUN; P=.001), procalcitonin (P=.03), C-reactive protein (CRP; P=.007), lactate dehydrogenase (LDH; P=.001), glucose (P=.01), temperature (P=.004), bilateral pulmonary infiltrates in chest x-rays (P<.001), and bilateral patchy opacity (P=.02). The results between the living and deceased subgroups of patients with confirmed SARS-CoV-2 (linking to or against mortality) were BMI (P=.04), length of stay (P<.001), hypertension (P=.02), multiple comorbidity (P=.045), BUN (P=.04), and EKG findings with arrhythmias or blocks (P=.02). Conclusions We arrived at the following conclusions based on a comprehensive review of our study group, data collection, and statistical analysis. Parameters that were strongly correlated with the need for mechanical ventilation were younger age group, overweight, Hispanic ethnicity, higher core body temperature, EKG findings with sinus tachycardia, and bilateral diffuse pulmonary infiltrates on the chest x-rays. Those intubated exhibited increased disease severity with significantly elevated levels of serum procalcitonin, CRP, LDH, mean glucose, creatinine, and BUN. Mortality was strongly correlated with BMI, African American ethnicity, hypertension, presence of multiple comorbidities (with a mean of 2.32), worsening renal function with acute kidney injury or acute chronic kidney injury, and EKG findings of arrhythmias and heart blocks.

Abstract Background: There are significant limitations in Haiti for the diagnosis and management of sickle cell disease (SCD), including the non-availability of universal newborn screening (NBS) and transcranial Doppler (TCD) ultrasound screening, and the lack of diagnostic laboratory resources, oral penicillin and hydroxyurea (HU). Methods: Beginning in September 2019, CSHSCD (R01HL149121), a 5-year NIH-sponsored observational comparative study of children with SCD from Haitian ethnicity in Miami and in Haiti compared to children of African American ethnicity with SCD, was designed to increase access to care in Haiti. The study aims are 1) to compare the incidence of SCD among newborns from Haitian and African American ethnicity in Miami, 2) to establish NBS programs for hemoglobinopathies in Haiti, and 3) to compare cohorts of children in SCD at the study sites. The participating sites are the University of Miami (UM, Miami, Florida), Hôpital Saint Damien (HSD, Tabarre, Haiti), Hôpital de l'Université d'Etat d'Haïti (HUEH, Port-au-Prince, Haiti), Hôpital Universitaire Justinien (HUJ, Cap Haitien, Haiti), and Hôpital Sacré Coeur (HSC, Milot, Haiti). HUJ and HSC use two NBS screening methods (isoelectric focusing and Sickle SCAN rapid test) and HSD and HUEH use isoelectric focusing only. CSHSCD supplies penicillin and HU and trains TCD examiners to implement stroke risk screening. Data are collected in REDCap. Results: During the first 2 years and despite the COVID-19 pandemic, we established NBS sites with a cohesive network of physicians and nurses trained in the care of children with SCD in Haiti. This capacity building will support sustainability of the program. We successfully identified at least 15 new cases of SCD via newborn screening, trained six TCD examiners, and enrolled 130 children with SCD in follow up, providing them with penicillin prophylaxis and hydroxyurea for severe cases according to local protocols . Implementation activities which have helped are close communications between the investigators, monthly Zoom meetings to coordinate efforts with enrollment updates every month, the availability of rapid tests (Sickle SCAN and Gazelle miniature cellulose acetate electrophoresis) for the diagnosis of SCD, especially when there is no laboratory equipment on site. Implementation challenges we have faced are mostly two. The first is the timely completion of DUNS and SAM registration for the two public hospitals, with one site achieving this after 9 months and the other site taking 18 months to complete. The reasons for the delay are the inability for the UM site to direct these efforts, following strict rules, and the Haitian hospital officers' lack of familiarity with website requirements. We were able to achieve these registrations with the assistance of one Haitian study staff who is very acquainted with internet navigation and became familiarized with requirements. Outsourcing materials to Haiti is another major challenge, with either gaps in the delivery of supplies because of multiple steps involved in ordering and shipping or with delays in releasing equipment once it is at the Port-au-Prince customs, resulting in gaps in NBS in one of the sites for 8 weeks. We have minimized these issues by opening a one-year ticket to order materials from the different companies involved. Also, Haiti's lack of infrastructure, available materials and medications, and political instability limit health care delivery. Conclusion: Since its inception, we have achieved major milestones, including capacity building and implementation of NBS, TCD training, and enrollment of children with SCD into the prospective cohorts despite the current COVID-19 pandemic. Material outsourcing challenges have been the major implementation problem we have faced due to systemic factors. We anticipate that these factors will be corrected or minimized as we have learned how to handle them. These problems were expected as part of conducting an international study in a low-resource setting. Acknowledgment: We acknowledge NHLBI for supporting this work.

Objective The frequency of endstage renal disease (ESRD) from systemic lupus erythematosus (SLE) in the United States has not improved over the last few decades in large population datasets. Understanding the risk factors for renal failure in SLE could lead to earlier detection of lupus nephritis and potentially more effective treatments in those with markers of poor prognosis. Methods The Hopkins Lupus Cohort, comprising 2528 patients was used. One hundred fifty-one patients experienced renal failure after SLE diagnosis, defined as dialysis or renal transplant. We estimated the risk of renal failure in subgroups defined by demographics, laboratory tests, and the American College of Rheumatology/Systemic Lupus International Collaborating Clinics (ACR/SLICC) classification criteria satisfied within 1 year of SLE diagnosis. Results The overall incidence of renal failure within 20 years of SLE diagnosis was 8.4%. The risk was much higher (20.0%) among those who experienced proteinuria within the first year of diagnosis. Demographic predictors included African American ethnicity [rate ratio (RR) 1.82, P = 0.0012] and age ≥ 40 years at SLE diagnosis (RR 0.51 vs those with diagnosis at < 30 yrs of age, P = 0.019). Among immunologic markers, low C3 was a strong predictor of renal failure (RR 2.00, P = 0.0011). Conclusion Proteinuria within the first year of diagnosis of SLE is one of the most important predictors of ESRD. Our data also confirm African American ethnicity, younger age at SLE diagnosis, and low C3 as strong predictors of renal failure.

Abstract Background: Blood stream infections (BSI) are a major source of morbidity and mortality after allogeneic blood and marrow transplantation (BMT). In studies of risk for BSI various factors have been identified. The impact of cytomegalovirus (CMV) viremia, however, on risk has not been assessed. This is important since both CMV infection and ganciclovir (GCV), the mainstay of pre-emptive therapy, have myelosuppressive and immunosuppressive effects. We conducted a retrospective analysis to test the hypothesis that CMV viremia predisposes allogeneic BMT patients to BSI. Methods: We retrospectively analyzed 278 allogeneic BMTs performed at Children's Healthcare of Atlanta between January 1st 2005 and December 31st 2014 that met eligibility criteria. The primary outcome was the first episode of BSI occurring between day +30 and +100 seen in engrafted patients following allogeneic BMT. We compared clinical characteristics between patients with and without BSI. This analysis was based on a time dependent competing risk model. Risk events including acute GVHD and CMV viremia were counted only when they preceded the BSI. We performed a multivariate analysis to estimate the effect of CMV viremia on risk for BSI in the post-engraftment period (days +30-100). Results: The median age was 9 years (range 0-22 years). 44.6% of the patients were Caucasian, while 38.5% were African-American. 59.7% received an unrelated marrow, unrelated cord or the alternative donor transplant. 60.8% were transplanted for a hematologic malignancy. The cumulative incidence of BSI between day +30 and+100 was 21.9% (95% confidence interval (CI), 17.5-27.3%). The median day of BSI development was 54 (range 30-99). The leading cause of BSI was Staphylococcus epidermidis. Gram-positive cocci were responsible for 71.4% of all BSIs. In the multivariate analysis, three factors were significant: grade III/IV aGVHD (hazard ratio (HR)=3.490, 95% CI 1.530-7.980, P=0.003), CMV viremia (HR=3.410, 95% CI 1.410-8.250, P=0.007), and African-American ethnicity (HR=2.520, 95% CI 1.130-5.600, P=0.024). Form of insurance (Medicaid/no insurance vs. other), employed as a surrogate for income level, had no influence on risk. In the 57 patients with CMV viremia, the frequency of neutropenia (<500/mm3) after the development of CMV viremia until day +100 was 26.3% (15/57), significantly higher than that observed in patients without CMV viremia (5.4% (12/221), P<0.001). Conclusion: Our analysis of risk for post-engraftment BSI in children yielded three factors. One, aGVHD, is well established. The other two, CMV viremia and African-American ethnicity, have not been previously recognized. That CMV viremia would predispose to subsequent BSI is highly plausible. Our results suggest that the risk of CMV viremia may be mediated in part by neutropenia stemming from CMV or its treatment with ganciclovir. That African-American ethnicity has not previously been recognized as a risk factor may simply reflect the ethnic make up of previous studies. Our findings are consistent with those of studies performed in other settings, showing patients of African descent to be at increased risk for bacteremia and sepsis. An increased risk for BSI among patients of African descent could partly explain the concerning excess risk for transplant related mortality previously observed among these patients. Disclosures No relevant conflicts of interest to declare.

ABSTRACT Screening for latent tuberculosis infection (LTBI) with Mantoux tuberculin skin test (TST) has many limitations, including false-positive results due to exposure to Mycobacterium other than tuberculosis (TB) and BCG vaccination. A total of 474 adult inmates in a county jail were screened for LTBI using TST and a new ESAT-6/CFP-10 peptide-based whole-blood gamma interferon (IFN-γ) assay. LTBI prevalence was 9.0 and 5.4% as determined by TST and IFN-γ assay, respectively. Overall, agreement between test results was 90% (κ = 0.25). Positive TST results were significantly associated with increased age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.01 to 1.08), African-American ethnicity (OR, 4.97; 95% CI, 1.58 to 15.68), foreign birth (OR, 20.20; 95% CI, 4.21 to 97.02) and prior incarceration (OR, 6.19; 95% CI, 1.48 to 25.95). Positive IFN-γ assay results were significantly associated with African-American ethnicity (OR, 5.58; 95% CI, 1.16 to 26.74). Factors associated with statistically significant discordance between TST and IFN-γ assay results were African-American ethnicity (OR, 0.29; 95% CI, 0.11 to 0.77), foreign birth (OR, 0.23; 95% CI, 0.07-0.80), and prior incarceration (OR, 0.06; 95% CI, 0.01-0.50). Among subjects born in the United States, African-American ethnicity was the only variable significantly associated with positive test results for both TST (OR, 4.26; 95% CI, 1.38 to 13.16) and IFN-γ assay (OR, 5.74; 95% CI, 1.19 to 27.75) and remained associated with statistically significant discordance between TST and IFN-γ assay results. The reactivity of the new IFN-γ assay is unaffected by prior BCG vaccination or serial TSTs but may be diminished in African-Americans. Future longitudinal studies are needed to assess the sensitivity and specificity of this new assay in detecting LTBI.
