RESUMO

Background and aim: Identifying clinical characteristics and outcomes of different ethnicities in the US may inform treatment for hospitalized COVID-19 patients. Aim of this study is to identify predictors of mortality among US races/ethnicities. Design Setting and participants: We retrospectively analyzed de-identified data from 9,873 COVID-19 patients who were hospitalized at 15 US hospital centers in 11 states (March 2020-November 2020). Main Outcomes and Measures: The primary outcome was to identify predictors of mortality in hospitalized COVID-19 patients. Results: Among the 9,873 patients, there were 64.1% African Americans (AA), 19.8% Caucasians, 10.4% Hispanics, and 5.7% Asians, with 50.7% female. Males showed higher in-hospital mortality (20.9% vs. 15.3%, p=0.001). Non- survivors were significantly older (67 vs. 61 years) than survivors. Patients in New York had the highest in-hospital mortality (OR=3.54 (3.03 - 4.14)). AA patients possessed higher prevalence of comorbidities, had longer hospital stay, higher ICU admission rates, increased requirement for mechanical ventilation and higher in-hospital mortality compared to other races/ethnicities. Gastrointestinal symptoms (GI), particularly diarrhea, were more common among minority patients. Among GI symptoms and laboratory findings, abdominal pain (5.3%, p=0.03), elevated AST (n=2653, 50.2%, p=<0.001, OR=2.18), bilirubin (n=577, 12.9%, p=0.01) and low albumin levels (n=361, 19.1%, p=0.03) were associated with mortality. Multivariate analysis (adjusted for age, sex, race, geographic location) indicates that patients with asthma, COPD, cardiac disease, hypertension, diabetes mellitus, immunocompromised status, shortness of breath and cough possess higher odds of in-hospital mortality. Among laboratory parameters, patients with lymphocytopenia (OR2=2.50), lymphocytosis (OR2=1.41), and elevations of serum CRP (OR2=4.19), CPK (OR2=1.43), LDH (OR2=2.10), troponin (OR2=2.91), ferritin (OR2=1.88), AST (OR2=2.18), D-dimer (OR2=2.75) are more prone to death. Patients on glucocorticoids (OR2=1.49) and mechanical ventilation (OR2=9.78) have higher in-hospital mortality. Conclusion: These findings suggest that older age, male sex, AA race, and hospitalization in New York were associated with higher in-hospital mortality rates from COVID-19 in early pandemic stages. Other predictors of mortality included the presence of comorbidities, shortness of breath, cough elevated serum inflammatory markers, altered lymphocyte count, elevated AST, and low serum albumin. AA patients comprised a disproportionate share of COVID-19 death in the US during 2020 relative to other races/ethnicities.

RESUMO

BACKGROUND: Long-COVID is a condition post SARS-CoV-2 infection with persistent or recurring symptoms affecting multiple organs, and may involve viral persistence, changes to the microbiome, coagulopathies, and alterations to neuro-immune interactions. These factors can disrupt the Gut-Brain Axis, which is a complex system involving bidirectional communication between the central nervous system and the gastrointestinal (GI) system. As a result of these disruptions, individuals with long-COVID may develop post-infectious functional GI disorders, which can cause a range of symptoms affecting the digestive system. AIM: To understand frequency of GI manifestations of Long-COVID and to determine association with sleep or neurological symptoms in a predominantly minority population. METHODS: We included patients with positive SARS-CoV-2 PCR (n = 747) who were hospitalized from Feb. 2020 to May 2021 at Howard University Hospital and followed between 6 and 12 months from discharge. GI, sleep, and neurological symptoms (via the Montreal Cognitive Assessment (MoCA) scoring system) were assessed using a standardized questionnaire. Linear regression analysis, χ2 and Fisher's exact test were utilized to determine the statistical significance of correlations of GI/Neuro/COVID. RESULTS: The mean age of patients was 58, with 51.6% females and a predominant African American ethnicity (73.6%, n = 550). A total of 108 patients died during their initial hospital stay, with the remaining 639 patients followed-up. Three hundred fifty (350) patients responded to the questionnaire (57 patients died during the follow-up period). Overall, 39 (13.3%) patients reported GI-related symptoms, out of which 19 (6.4%) had persistent symptoms and 20 (6.8%) developed new onset GI symptoms. Nausea and vomiting were the most common 24/39 (61.5%), followed by abdominal pain 7/39 (18%), diarrhea 5/39 (12.8%), and others 3/39 (7.6%). Patients who presented with vomiting during acute SARS-CoV-2 infection were more likely to have Long-COVID GI manifestations (P = 0.023). Use of ACE inhibitors, abnormal lymphocyte count and elevated ferritin are other variables that showed significant associations with Long-COVID GI manifestations (P = 0.03, 0.006 and 0.03, respectively). During follow-up, a total of 28 (9.5%) patients reported difficulty with sleep and 79 (27%) patients had abnormal MoCA assessment. With further analysis, there was a trend between presentation of GI symptoms on admission with abnormal MoCA assessment, and an association between abnormal LFTs and history of liver disease during hospitalization with subsequent sleep problems. Baseline characteristics, clinical comorbidities, other laboratory values, hospital length of stay, mechanical ventilation, medications during hospitalization, re-admission and Flu or COVID-19 vaccination have not shown any association with Long-COVID GI symptoms in our cohort. CONCLUSION: Dyspeptic symptoms were common GI manifestations in the acute and post COVID periods. GI symptoms, abnormal LFTs and a history of liver disease during the acute infectious phase associates with abnormal MoCA and sleep problems during follow-up. Further large population studies are needed to determine if COVID-19 leads to a GI symptoms-associated Long-COVID phenotypes and other symptoms through the Gut-Brain-Axis.

RESUMO

We present a case report of a non-ST segment elevation myocardial infarction (NSTEMI) occurring in an 89-year-old male with severe rhabdomyolysis and COVID-19 infection. The patient had a complex medical history, including non-ischemic cardiomyopathy, sinus bradycardia status post permanent pacemaker placement, and multiple comorbidities. He presented to the emergency department after a mechanical fall and was found to be COVID-19 positive. Despite the absence of typical symptoms, the patient's elevated troponin levels and electrocardiogram findings indicated NSTEMI. The initial management included an acute coronary syndrome protocol and admission to the cardiac intensive care unit. During the hospitalization, the patient developed acute hypoxic respiratory failure and was treated for COVID-19 pneumonia. The patient's renal function and creatine kinase levels showed improvement, and cardiac catheterization revealed non-obstructive coronaries. The patient was discharged in stable condition with a follow-up scheduled.

RESUMO

Infections in adult patients with hematological malignancies (HM) and stem cell transplant (SCT) recipients are a significant cause of morbidity and mortality. A timely diagnosis of infections can have a major impact on outcomes. Tools that help rule out infectious causes of fever can decrease antibiotic use, toxicities, hospitalization costs, and potentially decrease antibiotic resistance in the long term. We retrospectively evaluated the ability of cell-free DNA next-generation sequencing (NGS) testing in the timely identification of pathogenic microorganisms and its impact on the antimicrobial management of immunocompromised patients with hematologic malignancies. In the period between 2018 to 2020, 95 samples were reviewed, of which 31 adult patients (32 tests) had hematologic malignancies or were recipients of SCT. The NGS tests were performed in the following patients: (a) patients with prolonged fever and negative conventional tests, (b) persistent fever despite positive conventional test and appropriate antimicrobials, and (c) fever-free patients with imaging suspicious for infection. The median time from fever to NGS sampling was 5 days (range, 1-28). The median time to NGS results was 2 days (range, 1-6). The NGS resulted in an escalation of antibiotics in 28% of cases (9/32) and de-escalation of antibiotics in 31% of cases (10/32). Overall, NGS testing changed management in nearly 59% (19/32) of patients. The sensitivity and specificity of NGS to detect clinically significant infection was 80% and 58%, respectively. The test identified uncommon and difficult to diagnose organisms such as Nocardia, Legionella, Toxoplasma and Pneumocystis jirovecii resulting in rapid antimicrobial interventions. In conclusion, in patients with HM or SCT recipients, microbial cell-free DNA sequencing allowed rapid and actionable treatment. This strategy can target appropriate antibiotic use, avoid overtreatment, and potentially decrease the hospital length-of-stay.

RESUMO

Azacitidine (AZA) maintenance following allogeneic hematopoietic cell transplantation (HCT) for acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) may reduce relapse risk and improve survival. Given logistic and toxicity-related challenges, identifying subgroups appropriate for this approach is an unmet need. Using data from two centers, we retrospectively compared event-free survival (EFS) and overall survival (OS) of AML and MDS patients who received AZA maintenance (n = 59) with historic controls (n = 90). Controls were selected according to the following criteria: no death, relapse, or Grade III-IV acute GVHD for 100 days after transplant. In multivariable analysis, AZA maintenance yielded significantly improved EFS (p = 0.019) and OS (p = 0.011). Outcomes differed according to regimen intensity. For reduced-intensity transplant, EFS (p = 0.004) and OS (p = 0.004) were significantly improved and equivalent to myeloablative transplant. A significant benefit following myeloablative transplant was not observed. Within the limitation of its retrospective nature, this study suggests that AZA maintenance improves outcomes following reduced-intensity HCT, comparable to myeloablative HCT.

RESUMO

PREMISE OF STUDY: Herbaceous perennials are important long-lived plants in North American forests. Trillium has been used as a model organism to examine the effects of ecological processes on age structure in herbaceous forest perennials. Here, the methods of aging Trillium rhizomes are critically examined. • METHODS: Rhizomes of seedlings, single-bract plants, three-bract nonflowering plants, and flowering plants of Trillium erectum were examined. The patterns of cataphyll and scape scars on rhizomes were examined with respect to demographic category. • KEY RESULTS: Trillium rhizomes produce two cataphyll scars per year on single-bract, three-bract nonflowering, and flowering plants. Scape scars were only evident on rhizomes of three-leaved nonflowering and flowering plants. The percentage of intact rhizomes ranged from 10-67% for three-bract nonflowering plants, and 0-51% for flowering plants. Rhizomes in all demographic categories had evidence of recessing tissues from the oldest portion of the rhizome indicating that accurate age estimates are not possible on many plants. • CONCLUSIONS: Accepted methods of aging Trillium rhizomes have significant drawbacks. The primary problem is that rhizomes rot from the oldest portions in all demographic categories. A second problem is that plants producing multiple scape scars in a given year could mistakenly be counted as multiple years. Finally, confusing terminology and misrepresentations in Trillium literature suggests that many previous studies did not correctly determine age. Given the challenges of aging Trillium, we suggest that future studies use rhizome aging to study early demographic stages only and the ecological processes that influence their growth.

RESUMO

Rising health care costs have led to an emphasis on identifying factors that contribute to medical service utilization. Previous research has suggested an association between youth psychopathology and service utilization; however, prospective studies among high-risk populations are needed. The current study examined youth psychopathology as a predictor of subsequent medical service utilization among a large sample (N = 536) of youth entering residential treatment. Youth psychopathology and medical status were assessed at intake, and medical service utilization was tracked across the duration of the residential placement. Results indicated that higher levels of psychopathology predicted greater youth medical service utilization, even after controlling for the presence of a diagnosed medical condition. Internalizing problems was a significant independent predictor of utilization, but externalizing problems was not. These findings highlight the association between mental health and medical service utilization and suggest that effective behavioral health services may be helpful in reducing costly medical service needs.

RESUMO

OBJECTIVE: To examine the prevalence of physical health problems among youth entering residential treatment. PATIENTS AND METHODS: The sample included 1744 youth (mean age: 14.6 ± 1.8 years) entering a large residential treatment program between 2000 and 2010. Youth received an intake medical evaluation, including a review of available records, detailed medical history, and physical examination. Medical conditions present at the time of the evaluation were recorded by the examining physician and later coded by the research team. Only diagnoses recognized by the International Classification of Diseases, 10th Revision, were included in the analyses. To maintain the focus on physical health problems, behavioral and emotional disorders listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision were excluded. Obesity, acne, and allergies were also excluded. RESULTS: Approximately one-third (33.7%) of youth had a physical health diagnosis at the time of intake. Asthma was the most prevalent condition diagnosed (15.3% of the sample). Girls were significantly more likely to have a diagnosis than were boys (37.1% vs 31.5%). Age was not associated with diagnostic status. Rates of physical health conditions differed significantly by ethnicity: black (36.4%) and white (35.4%) youth had the highest rates, and Hispanic youth (23.2%) had the lowest. CONCLUSIONS: Youth who enter residential treatment have high rates of physical health conditions. These problems could complicate mental health treatment and should be considered in multidisciplinary treatment planning.
