RESUMO
BACKGROUND: The prevalence of steatotic liver disease (SLD) among patients with rheumatoid arthritis (RA) remains largely unknown. AIMS: To investigate the prevalence of SLD and liver fibrosis among patients with RA. METHODS: We utilized data from the United States (US)-based National Health and Nutrition Examination Survey (NHANES) 2017-2020 cycle. After applying established sample weights, we estimated the age-adjusted prevalence of SLD and its subclassifications (CAP ≥ 285 dB/m), high-risk NASH (FAST score) and liver fibrosis (LSM) among participants with self-reported RA. Multivariable logistic regression was performed to identify independent risk factors for metabolic dysfunction associated SLD (MASLD), high-risk NASH and fibrosis, respectively, among participants with RA. We present adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: Age-adjusted prevalence of MASLD among US adults with RA was 34.91% (95% CI: 24.02-47.65%). We also found that the age-adjusted prevalence of high-risk NASH (FAST score > 0.35) and significant fibrosis (LSM > 8.6 kPa) was 12.97% (95% CI: 6.89-23.07%) and 10.35% (95% CI: 5.55-18.48%), respectively. BMI ≥ 30 kg/m2, (aOR 6.23; 95% CI: 1.95-19.88), diabetes (aOR 5.90; 95% CI: 1.94-17.94), and dyslipidemia (aOR 2.83; 95% CI: 1.12-7.11) were independently associated with higher odds of MASLD among participants with RA. Diabetes (aOR 19.34; 95% CI: 4.69-79.70) was also independently associated with high-risk NASH. CONCLUSIONS: The prevalence of MASLD, high-risk NASH, and liver fibrosis among patients with RA is equal or higher than the general population. Future studies of large cohorts are needed to substantiate the role of systemic inflammation in the pathophysiology of MASLD.

BACKGROUND: Thymosin-α-1 (Tα1) may be a treatment option for coronavirus disease 2019 (COVID-19), but efficacy and safety data remain limited. METHODS: Prospective, open-label, randomized trial assessing preliminary efficacy and safety of thymalfasin (synthetic form of Tα1), compared with the standard of care, among hospitalized patients with hypoxemia and lymphocytopenia due to COVID-19. RESULTS: A total of 49 patients were included in this analysis. Compared with control patients, the incidence of clinical recovery was higher for treated patients with either baseline low-flow oxygen (subdistribution hazard ratio, 1.48 [95% confidence interval, .68-3.25]) or baseline high-flow oxygen (1.28 [.35-4.63]), although neither difference was significant. Among patients with baseline low-flow oxygen, treated patients, compared with control patients, had an average difference of 3.84 times more CD4+ T cells on day 5 than on day 1 (P = .01). Nine serious adverse events among treated patients were deemed not related to Tα1. CONCLUSIONS: Tα1 increases CD4+ T-cell count among patients with baseline low-flow oxygen support faster than the standard of care and may have a role in the management of hospitalized patients with hypoxemia and lymphocytopenia due to COVID-19. CLINICAL TRIALS REGISTRATION: NCT04487444.

Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease. The association between prior hepatitis B virus (HBV), hepatitis A virus (HAV), hepatitis E virus (HEV) infection and NAFLD remains unclear. We utilized the 2017-2020 National Health and Nutrition Examination Survey (NHANES) and performed multivariable logistic regression analyses to examine the association of prior HBV, HAV and HEV infection with NAFLD, as well as high risk non-alcoholic steatohepatitis (NASH) and liver fibrosis. Our analysis included 2565 participants with available anti-HBc serology results, 1480 unvaccinated participants with anti-HAV results, and 2561 participants with anti-HEV results. Among participants with NAFLD, the age-adjusted prevalence of prior HBV, HAV and HEV infection was 3.48%, 32.08% and 7.45%, respectively. Prior infection with HBV, HAV and HEV was not associated with NAFLD (cut-off 285 dB/m) [aOR: 0.99 (95% CI, 0.77-1.29), 1.29 (95% CI, 0.95-1.75), and 0.94 (95% CI, 0.70-1.27), respectively] or high-risk NASH [aOR 0.72 (95% CI, 0.45-1.17), 0.92 (95% CI, 0.55-1.52), and 0.89 (95% CI, 0.41-1.94), respectively]. Participants with anti-HBc and anti-HAV seropositivity were more likely to have significant fibrosis [aOR: 1.53 (95% CI, 1.05-2.23) and 1.69 (95% CI, 1.16-2.47), respectively]. The odds of significant fibrosis are 53%, and 69% greater for participants with prior history of HBV and HAV infection. Healthcare providers should prioritize vaccination efforts and employ a tailored approach to NAFLD in patients with prior viral hepatitis and especially HBV or HAV infection to limit disease-related outcomes.

Objectives. To identify spatiotemporal patterns of epidemic spread at the community level.Methods. We extracted influenza cases reported between 2016 and 2019 and COVID-19 cases reported in March and April 2020 from a hospital network in Rhode Island. We performed a spatiotemporal hotspot analysis to simulate a real-time surveillance scenario.Results. We analyzed 6527 laboratory-confirmed influenza cases and identified microepidemics in more than 1100 neighborhoods, and more than half of the neighborhoods that had hotspots in a season became hotspots in the next season. We used data from 731 COVID-19 cases, and we found that a neighborhood was 1.90 times more likely to become a COVID-19 hotspot if it had been an influenza hotspot in 2018 to 2019.Conclusions. The use of readily available hospital data allows the real-time identification of spatiotemporal trends and hotspots of microepidemics.Public Health Implications. As local governments move to reopen the economy and ease physical distancing, the use of historic influenza hotspots could guide early prevention interventions, while the real-time identification of hotspots would enable the implementation of interventions that focus on small-area containment and mitigation.

Background: Rapid initiation of antiretroviral therapy (rapid ART) improves clinical outcomes in people with HIV and is endorsed by clinical guidelines. However, logistical challenges limit widespread implementation. We describe an innovative rapid ART model led by pharmacists and its impact on clinical outcomes, including time to viral suppression (TVS). Methods: On 1 January 2019, we implemented Pharmacist-Driven Rapid ART (PHARM-D RAPID ART), including rapid ART initiation by pharmacists. Our retrospective cohort study compared TVS, using a Cox proportional hazards model, and clinical outcomes among individuals with a new HIV diagnosis before (1 January 2017 to 31 December 2017) and after (1 January 2019 to 31 December 2019) implementation. Results: A total of 108 individuals were included. TVS was significantly shorter (P < .001) for the PHARM-D RAPID ART group (n = 51) compared with the preimplementation group (n = 57) (median: 30 days and 66 days, respectively). Those in the PHARM-D RAPID ART group were significantly more likely to achieve VS at any given time during the study period (adjusted hazard ratio: 3.47 [95% confidence interval, 2.25-5.33]). A total of 94.1% (48/51) of patients in the PHARM-D RAPID ART group were retained in care at 1 year. With a median follow-up of 2.4 years in the PHARM-D RAPID ART group, 98% remained suppressed at last recorded viral load. Conclusions: A pharmacist-driven model for rapid ART delivery decreases TVS with high rates of retention in care and durable VS. This model could improve clinical outcomes and increase program feasibility and sustainability.
RESUMO
BACKGROUND: Early in the pandemic, extensive attention was cast on limited inclusion of historically underrepresented patient populations in COVID-19 clinical trials. How diverse representation improved following these initial reports remains unclear. METHODS: PubMed, Embase and the Cochrane Library were searched (through April 2024) for US-based COVID-19 trials. Utilizing random-effects, we compared expected proportions of trial participants from racial and ethnic groups and of female sex between trials enrolling primarily in 2020 versus primarily 2021-2022. Meta-regression was performed to assess associations between trial characteristics and group representation. RESULTS: We retrieved 157 studies comprising 198,012 participants. White (2020: 63.1% [95% CI, 60.8%-67.3%]; 2021-2022: 73.8% [95% CI, 71.5%-76.0%]) and female representation (2020: 46.1% [95% CI, 44.7%-47.4%)]; 2021-2022: 51.1% [95% CI, 49.3%-52.8%) increased across enrollment periods. Industry-sponsored trials were associated with higher White (coefficient, 0.10 [95% CI, 0.03-0.18]) and Hispanic or Latinx representation (coefficient, 0.16 [95% CI, 0.08-0.25]) and lower Asian (coefficient, -0.03 [95% CI, -0.06- -0.003]) and female representation (coefficient, -0.03 [95% CI, -0.07- -0.002]). Outpatient trials were associated with higher White (coefficient, 0.20 [95% CI, 0.13-0.26]) and female representation (coefficient, 0.16 [95% CI, 0.13-0.18]), and lower Black representation (coefficient, -0.10 [95% CI, -0.10- -0.08]). CONCLUSIONS: Despite improved female representation in COVID-19 trials over time, there was no clear increase in non-White representation. Trial characteristics such as primary sponsor, clinical setting, and intervention type correlate with representation of specific demographic groups and should be considered in future efforts to improve participant diversity.

Background: Clinical trials for coronavirus disease 2019 (COVID-19) have struggled to achieve diverse patient enrollment, despite underrepresented groups bearing the largest burden of the disease and, presumably, being most in need of the treatments under investigation. Methods: To assess the willingness of patients to enroll into inpatient COVID-19 clinical trials when invited, we conducted a cross-sectional analysis of adults hospitalized with COVID-19 who were approached regarding enrollment. Associations between patient and temporal factors and enrollment were assessed by multivariable logistic regression analysis. Results: A total of 926 patients were included in this analysis. Overall, Hispanic/Latinx ethnicity was associated with a nearly half-fold decrease in the likelihood to enroll (adjusted odds ratio [aOR], 0.60 [95% confidence interval {CI}, .41-.88]). Greater baseline disease severity (aOR, 1.09 [95% CI, 1.02-1.17]), age 40-64 years (aOR, 1.83 [95% CI, 1.03-3.25]), and age ≥65 years (aOR, 1.92 [95% CI, 1.08-3.42]) were each independently associated with higher likelihood to enroll. Over the course of the pandemic, patients were less likely to enroll during the summer 2021 wave in COVID-19-related hospitalizations (aOR, 0.14 [95% CI, .10-.19]) compared with patients from the first wave in winter 2020. Conclusions: The decision to enroll into clinical trials is multifactorial. Amid a pandemic disproportionately affecting vulnerable groups, Hispanic/Latinx patients were less likely to participate when invited, whereas older adults were more likely. Future recruitment strategies must consider the nuanced perceptions and needs of diverse patient populations to ensure equitable trial participation that advances the quality of healthcare for all.
RESUMO
(1) Background: Respiratory co-infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other viruses are common, but data on clinical outcomes and laboratory biomarkers indicative of disease severity are limited. We aimed to compare clinical outcomes and laboratory biomarkers of patients with SARS-CoV-2 alone to those of patients with SARS-CoV-2 and either rhinovirus or adenovirus. (2) Methods: Hospitalized patients co-infected with SARS-CoV-2 and rhinovirus and patients co-infected with SARS-CoV-2 and adenovirus were matched to patients infected with SARS-CoV-2 alone. Outcomes of interest were the cumulative incidences of mechanical ventilation use, intensive care unit (ICU) admission, 30-day all-cause mortality, and 30-day all-cause readmission from the day of discharge. We also assessed differences in laboratory biomarkers from the day of specimen collection. (3) Results: Patients co-infected with SARS-CoV-2 and rhinovirus, compared with patients infected with SARS-CoV-2, had significantly greater 30-day all-cause mortality (8/23 (34.8%) vs. 8/69 (11.6%), p = 0.02). Additionally, median alanine transaminase (13 IU/L vs. 24 IU/L, p = 0.03), aspartate transaminase (25 IU/L vs. 36 IU/L, p = 0.04), and C-reactive protein (34.86 mg/L vs. 94.68 mg/L, p = 0.02) on day of specimen collection were significantly lower in patients co-infected with SARS-CoV-2 and rhinovirus in comparison to patients infected with SARS-CoV-2 alone. Clinical outcomes and laboratory markers did not differ significantly between patients with SARS-CoV-2 and adenovirus co-infection and patients with SARS-CoV-2 mono-infection. (4) Conclusion: SARS-CoV-2 and rhinovirus co-infection, compared with SARS-CoV-2 mono-infection alone, is positively associated with 30-day all-cause mortality among hospitalized patients. However, our lack of significant findings in our analysis of patients with SARS-CoV-2 and adenovirus co-infection may suggest that SARS-CoV-2 co-infections have variable significance, and further study is warranted.

Background: Biologic (bDMARD) and targeted synthetic (tsDMARD) disease-modifying anti-rheumatic drugs have broadened the treatment options and are increasingly used for patients with psoriatic arthritis (PsA). These agents block different pro-inflammatory cytokines or specific intracellular signaling pathways that promote inflammation and can place patients at risk of serious infections. We aimed to review the incidence of opportunistic infections (OIs) in patients with PsA who were treated with these agents. Methods: We searched PubMed and EMBASE through 14 April 2022 for randomized clinical trials evaluating bDMARD or tsDMARD in the treatment of PsA. Trials were eligible if they compared the effect of a bDMARD or tsDMARD with placebo and provided safety data. We used the Revised Cochrane risk-of-bias tool to assess the risk of bias among trials, and stratified the studies by mechanism of action (MOA) of the agents studied. Results: We included 47 studies in this analysis. A total of 17,197 patients received at least one dose of an agent of interest. The cumulative incidence of OIs by MOA was as follows: 1) JAK inhibitors: 2.72% (95% CI: 1.05%-5.04%), 2) anti-IL-17: 1.18% (95% CI: 0.60%-1.9%), 3) anti-IL-23: 0.24% (95% CI: 0.04%-0.54%), and 4) anti-TNFs: 0.01% (95% CI: 0.00%-0.21%). Based on their MOA, these agents are known to increase the risk of certain serious infections. The cumulative incidence of herpes zoster infection following treatment with JAK inhibitors (JAKi) was 2.53% (95% CI: 1.03%-4.57%) and the cumulative incidence of opportunistic Candida spp. infections following treatment with anti-IL-17, was 0.97% (95% CI: 0.51%-1.56%). Conclusion: The overall incidence of OIs among patients with PsA who were treated with biologic and targeted synthetic agents is low. However, careful monitoring is warranted for specific OIs such as herpes zoster infection following JAKi treatment, mucocutaneous candidiasis following anti-IL-17 treatment, and Mycobacterium tuberculosis infection following anti-TNF treatment.
RESUMO
(1) Background: Ceftriaxone is a potential alternative for the treatment of methicillin-susceptible Staphylococcus aureus (MSSA) bloodstream infections (BSIs) in acute care and outpatient parenteral antimicrobial therapy (OPAT) settings. We evaluated the effectiveness and safety of ceftriaxone for the treatment of MSSA BSIs. (2) Method: We searched PubMed, Embase, and Cochrane Library from their inception to October 30th 2021. Our outcomes included clinical cure, microbiological cure, 30- and 90-day mortality, 90-day hospital readmission, and adverse drug reactions (ADRs). We compared ceftriaxone against standard of care (SOC) therapy. We used the random-effects model for the meta-analysis, and our estimated effects were reported as odds ratios (ORs) with 95% confidence intervals (CI). (3) Results: Twelve retrospective cohort studies were included, comprising 1037 patients in the ceftriaxone arms and 2088 patients in the SOC arms. The clinical cure rate of the ceftriaxone regimen was not statistically different from SOC: OR 0.65 (95% CI: 0.29-1.45). Ceftriaxone was also not statistically different from SOC in microbiological cure: OR 1.48 (95% CI: 0.29-7.51); 30-day mortality: OR 0.79 (95% CI: 0.14-4.65); 90-day mortality: OR 0.82 (95% CI: 0.38-1.80); 90-day hospital readmission: OR 1.20 (95% CI: 0.92-1.56); and ADRs: OR 0.92 (95% CI: 0.39-2.18). (4) Conclusion: Ceftriaxone could provide an alternative for the treatment of MSSA BSIs in acute care and OPAT settings (except in patients whose BSIs were due to infective endocarditis).
RESUMO
(1) Background: Clostridioides difficile infection (CDI) is associated with a high recurrence rate, and a significant proportion of patients with CDI are readmitted following discharge. We aimed to identify the risk factors for CDI-related readmission within 90 days following an index hospital stay for CDI. (2) Methods: We analyzed the electronic medical data of admitted patients in our health system over a two-year period. A multivariate logistic regression model, supplemented with bias-corrected and accelerated confidence intervals (BCa-CI), was implemented to assess the risk factors. (3) Results: A total of 1253 adult CDI index cases were included in the analysis. The readmission rate for CDI within 90 days of discharge was 11% (140/1253). The risk factors for CDI-related readmission were fluoroquinolone exposure within 90 days before the day of index CDI diagnosis (aOR: 1.58, 95% CI: 1.05-2.37), higher Elixhauser comorbidity score (aOR: 1.05, 95% CI: 1.02-1.07), and being discharged home (aOR: 1.64, 95% CI: 1.06-2.54). In contrast, a longer length of index stay (aOR: 0.97, 95% BCa-CI: 0.95-0.99) was associated with reduced odds of readmission for CDI. (4) Conclusion: More than 1 out of 10 patients were readmitted for CDI following an index hospital stay for CDI. Patients with recent previous fluoroquinolone exposure, greater overall comorbidity burden, and those discharged home are at higher risk of readmission for CDI.
RESUMO
OBJECTIVE: The aim of this study was to explore the potential association of obesity and other chronic diseases with severe outcomes, such as intensive care unit (ICU) admission and invasive mechanical ventilation (IMV), in patients hospitalized with coronavirus disease 2019 (COVID-19). METHODS: This study analyzed a retrospective cohort of 103 patients hospitalized with COVID-19. Demographic data, past medical history, and hospital course were collected and analyzed. A multivariate logistic regression analysis was implemented to examine associations. RESULTS: From February 17 to April 5, 103 consecutive patients were hospitalized with COVID-19. Among them, 44 patients (42.7%) were admitted to the ICU, and 29 (65.9%) required IMV. The prevalence of obesity was 47.5% (49 of 103). In a multivariate analysis, severe obesity (BMI ≥ 35 kg/m2 ) was associated with ICU admission (adjusted odds ratio [aOR]: 5.39, 95% CI: 1.13-25.64). Moreover, patients who required IMV were more likely to have had heart disease (aOR: 3.41, 95% CI: 1.05-11.06), obesity (BMI = 30-34.9 kg/m2 ; aOR: 6.85, 95% CI: 1.05-44.82), or severe obesity (BMI ≥ 35 kg/m2 ; aOR: 9.99, 95% CI: 1.39-71.69). CONCLUSIONS: In our analysis, severe obesity (BMI ≥ 35 kg/m2 ) was associated with ICU admission, whereas history of heart disease and obesity (BMI ≥ 30 kg/m2 ) were independently associated with the use of IMV. Increased vigilance and aggressive treatment of patients with obesity and COVID-19 are warranted.

We evaluated the statewide burden of obesity and its complications among government and state funded programs (Medicare and Medicaid) and commercial insurance.We calculated the prevalence of obesity and the prevalence of relevant comorbidities among different demographic groups and based on health insurance, among adults (18-65 years old) who visited a statewide health network in the state of Rhode Island, in 2017.The overall prevalence of obesity among 74,089 individuals was 38.88% [Asians 16.77%, Whites 37.49%, Hispanics 44.23%, and Blacks 48.44%]. Medicare or Medicaid beneficiaries were 26% and 27%, respectively, more likely to have obesity than those who had commercial insurance (Odds Ratio:1.26, 95% confidence interval [CI]:1.20-1.32; Odds Ratio:1.27, 95%CI:1.22-1.32). Moreover, Medicaid and Medicare beneficiaries with obesity had a higher prevalence of diabetes compared with privately insured with obesity (10.58% and 10.44% vs 4.45%). Medicare beneficiaries with obesity had a statistically higher prevalence of ischemic heart disease (4.34%, 95%CI: 3.77-4.91) than privately insured (3.21%, 95%CI: 2.94-3.47).Based on statewide data among 18 to 65 years old adults, Medicare and Medicaid provide health coverage to 40% of individuals with obesity and 46% of those with the obesity-related comorbidities and complications. State and federal health care programs need to support and expand obesity-related services and coverage.

BACKGROUND: There are few large prospective cohort studies evaluating predictors of outcomes in acute pancreatitis. OBJECTIVES: The purpose of this study was to determine the role of age and co-morbid disease in predicting major outcomes in acute pancreatitis. METHODS: Data points were collected according to a predefined electronic data collection form. Acute pancreatitis and its complications were defined according to the revised Atlanta classification. Univariable and multivariable analyses were conducted using Cox proportional hazard regression and multiple logistic regression. RESULTS: From June 2013-February 2015, 1655 adult patients were recruited from 23 centres across Spain. Co-morbid disease, obesity, open surgical necrosectomy within 30 days, and pancreatic necrosis were independently associated with both 30-day mortality and persistent organ failure (p < 0.05 for all). Age was not associated with persistent organ failure, however the extreme of age (>85 years) was associated with mortality (p < 0.05). Co-morbid disease and obesity were not independently associated with a prolonged length of stay or other markers of morbidity on adjusted analysis (p > 0.05). CONCLUSION: Comorbidity and obesity are important determinates of mortality and persistent organ failure in acute pancreatitis, but in the absence of organ failure they do not appear to independently contribute to morbidity. This has important implications for severity classification and predictive models of severity in acute pancreatitis.
RESUMO
Presentamos el caso de un niño de 9 años de edad, en quien como hallazgo incidental en una radiografía de tórax se observa una calcificación en el hipocondrio izquierdo sugestiva de masa. Se amplía el estudio mediante ecografía y resonancia magnética (RM) abdominal para mejor caracterización: se visualiza una masa suprarrenal izquierda, predominantemente quística, con un nódulo sólido. Finalmente, se le practica una resección quirúrgica, en la cual se llega al diagnóstico de ganglioneuroblastoma nodular quístico, tras el análisis histopatológico. El ganglioneuroblastoma quístico es un tumor poco frecuente, originado en las células ganglionares del sistema nervioso simpático. El sitio de origen más frecuente son las glándulas suprarrenales. A pesar de que el diagnóstico definitivo se suele realizar tras la resección quirúrgica del tumor, con la ecografía y la RM se debe incluir entre los diagnósticos diferenciales de incidentalomas suprarrenales en un niño o un paciente joven. Los hallazgos en tomografía computarizada son variables.
We present the case of a child patient aged 9 years, in whom, as an incidental finding in chest X-rays, a calcified lesion was observed in the left hypochondrium. The study is extended by ultrasound and then MRI was performed to better characterize it. These showed a left adrenal, predominantly cystic mass with a solid nodule. The surgical team decided to perform resection of the mass and submit it for histopathological examination. A definitive diagnosis of cystic nodular ganglioneuroblastoma was made. Ganglioneuroblastoma is a rare tumour, originating in ganglion cells of the sympathetic nervous system. The site of more frequent origin is in the adrenal glands. Although the majority are diagnosed based on the postoperative histological analysis, with ultrasound and MRI we should include it among the differentials diagnoses of adrenal incidentalomas in a child or young patient. The findings on CT are variables.

OBJECTIVE: To determine if hepatic lipomas have a higher prevalence of liver steatosis than other benign hepatic lesions. MATERIALS AND METHODS: Ninety-two benign hepatic lesions were analyzed with magnetic resonance (MR) imaging. There were 6 lipomas and 86 benign non-lipomatous lesions, including 55 hemangiomas, 23 focal nodular hyperplasias (FNH) and 8 adenomas. All studies included a chemical shift T1-weighted sequence (in-phase and opposed-phase) in order to evaluate the presence of steatosis. RESULTS: A statistically significant relationship (Fischer's Exact Test, p=0.019) between hepatic lipomas and steatosis was demonstrated. Fifty percent of hepatic lipomas associated steatosis, while this association was present in only 9% of the non-lipomatous lesions. CONCLUSION: Lipomas have a significantly greater association with steatosis when compared to nonlipomatous lesions. This relationship may be related to a common insuline resistance mechanism.
