A phase 1 study of regorafenib and sildenafil in adults with advanced solid tumors.

The purpose of this study is to establish the recommended phase 2 dose for regorafenib in combination with sildenafil for patients with advanced solid tumors. Secondary outcomes included identification of antitumor effects of regorafenib and sildenafil, toxicity of the combination, determination of PDE5 expression in tumor samples, and the impact of sildenafil on the pharmacokinetics of regorafenib. This study was a phase 1, open-label single-arm dose-escalation trial using a 3 + 3 design. Additional patients were enrolled at the maximum tolerated dose (MTD) until a total of 12 patients were treated at the MTD. A total of 29 patients were treated in this study. The median duration of treatment was 8 weeks. The recommended phase 2 doses determined in this study are regorafenib 160 mg daily with sildenafil 100 mg daily. The most common toxicities included palmar-plantar erythrodysesthesia syndrome (20 patients, 69%) and hypophosphatemia (18 patients, 62%). Two patients (7%) experienced grade 4 lipase increase. Objective responses were not observed; however, 14 patients (48%) had a period of stable disease during the study. Stable disease for up to 12 months was observed in patients with ovarian cancer as well as up to 20 months for a patient with cervical cancer. The combination of regorafenib and sildenafil at the recommended phase 2 dose is safe and generally well tolerated. Disease control in patients with gynecologic malignancies was especially encouraging. Further evaluation of the combination of regorafenib and sildenafil in gynecologic malignancies is warranted. Clinical Trial Registration Number: NCT02466802.

Factors Influencing Medication Administration Outcomes Among New Graduate Nurses Using Bar Code-Assisted Medication Administration.

Paramount to patient safety is the ability for nurses to make clinical decisions free from human error. Yet, the dynamic clinical environment in which nurses work is characterized by uncertainty, urgency, and high consequence, necessitating that nurses make quick and critical decisions. The aim of this study was to examine the influence of human and environmental factors on the decision to administer among new graduate nurses in response to alert generation during bar code-assisted medication administration. The design for this study was a descriptive, longitudinal, observational cohort design using EHR audit log and administrative data. The study was set at a large, urban medical center in the United States and included 132 new graduate nurses who worked on adult, inpatient units. Research variables included human and environmental factors. Data analysis included descriptive and inferential analyses. This study found that participants continued with administration of a medication in 90.75% of alert encounters. When considering the response to an alert, residency cohort, alert category, and previous exposure variables were associated with the decision to proceed with administration. It is important to continue to study factors that influence nurses' decision-making, particularly during the process of medication administration, to improve patient safety and outcomes.

Leadership Behaviors of Frontline Nurse Managers: A Mixed-Methods Research Study Identifying Essential Areas for Social Support.

OBJECTIVE: This study examined how frontline nurse managers (FLNMs) perceive and experience formal and informal social support and how personal factors and social support relate to their transformational leadership (TL) behaviors. BACKGROUND: Ineffective leadership by FLNMs is associated with costly outcomes. Evidence suggests that leadership development is a function of personal and social factors; however, a better understanding of this process is needed. METHODS: A convergent mixed-methods design was used. The quantitative strand included a cross-sectional survey in a sample of FLNMs. The qualitative strand used a semistructured interview and a descriptive qualitative approach with a subset of this sample. RESULTS: Formal and informal social support is positively related to the TL behaviors of FLNMs as evidenced by the convergent data. The influence of family members in the work-related decisions of FLNMs has been underreported in the literature and is an area for consideration in supporting retention and desired leadership behaviors. CONCLUSION: The findings of this study imply a need for organizations to establish systems that endorse the growth of FLNMS, create opportunities for career advancement, and integrate members of the FLNMs' personal support systems into recognition initiatives.

Describing Medication Administration and Alert Patterns Experienced by New Graduate Nurses During the First Year of Practice.

The aim of this study was to describe medication administration and alert patterns among a cohort of new graduate nurses over the first year of practice. Medical errors related to clinical decision-making, including medication administration errors, may occur more frequently among new graduate nurses. To better understand nursing workflow and documentation workload in today's clinical environment, it is important to understand patterns of medication administration and alert generation during barcode-assisted medication administration. Study objectives were addressed through a descriptive, longitudinal, observational cohort design using secondary data analysis. Set in a large, urban medical center in the United States, the study sample included 132 new graduate nurses who worked on adult, inpatient units and administered medication using barcode-assisted medication administration. Data were collected through electronic health record and administration sources. New graduate nurses in the sample experienced a total of 587 879 alert and medication administration encounters, administering 772 unique medications to 17 388 unique patients. Nurses experienced an average medication workload of 28.09 medications per shift, 3.98% of which were associated with alerts, over their first year of practice. In addition to high volume of medication administration, new graduate nurses administer many different types of medications and are exposed to numerous alerts while using barcode-assisted medication administration.

Predictors of Respiratory Failure Development in A Multi-Center Cohort of Inpatients with Cirrhosis.

OBJECTIVES: Hospitalized patients with cirrhosis can develop respiratory failure (RF), which is associated with a poor prognosis but predisposing factors are unclear. METHODS: We prospectively enrolled a multi-center North American cirrhosis inpatient cohort and collected admission and in-hospital data [grading per EASL-CLIF scoring system, acute kidney injury (AKI), infections (admission/nosocomial) and albumin use] in an era when terlipressin was not available in North America. Multi-variable regression to predict RF was performed using only admission day, and in-hospital events occurring prior to RF. RESULTS: 511 patients from 14 sites (median 57 years, admission MELD-Na 23) were enrolled: RF developed in 15%; AKI occurred in 24%; and 11% developed nosocomial infections (NI). At admission, patients who developed RF had higher MELD-Na, GI bleeding/AKI-related admission, and prior infections/ascites. During hospitalization, RF developers had higher NI (especially respiratory), albumin use, and other organ failures. RF was higher in patients receiving albumin (83% vs 59%,p<0.0001) with increasing doses (269.5±210.5 vs 208.6±186.1 gm,p=0.01) regardless of indication. MULTIVARIABLE ANALYSIS: Admission for AKI, GI bleeding and high MELD-Na predicted RF. Using all variables, NI (OR:4.02,p=0.0004), GI bleeding (OR:3.1,p=0.002), albumin use (OR:2.93,p=0.01), AKI (OR:3.26,p=0.008) and circulatory failure (OR:3.73,p=0.002) were associated with RF risk. CONCLUSIONS: In a multi-center inpatient cirrhosis study of patients not exposed to terlipressin, 15% patients developed RF. RF risk was highest in those admitted with AKI, had GI bleeding on admission and those who developed nosocomial infections, and other organ failures, or received albumin during their hospital course. Careful volume monitoring and preventing nosocomial respiratory infections, renal or circulatory failures could reduce this risk.

Low-Income Older Adults' Vulnerability to Anticholinergic Medication-Associated Frailty.

BACKGROUND: A growing body of research supports the negative impact of anticholinergic drug burden on physical frailty. However, prior research has been limited to homogeneous white European populations, and few studies have evaluated how anticholinergic burden tools compare in their measurement function and reliability with minority community-dwelling adult populations. This study investigated the association between anticholinergic drug exposure and frailty by conducting a sensitivity analysis using multiple anticholinergic burden tools in a diverse cohort. METHODS: A comprehensive psychometric approach was used to assess the performance of five clinical Anticholinergic Burden Tools: Anticholinergic Cognitive Burden Scale (ACB), Anticholinergic Drug Scale (ADS), average daily dose, total standardized daily doses (TSDD), and Cumulative Anticholinergic Burden scale (CAB). Spearman correlation matrix and intraclass correlation coefficients (ICC) were used to determine the association among the variables. Ordinal logistic regression is used to evaluate the anticholinergic burden measured by each scale to determine the prediction of frailty. Model performance is determined by the area under the curve (AUC). RESULTS: The cohort included 80 individuals (mean age 69 years; 55.7% female, 71% African American). All anticholinergic burden tools were highly correlated (p < 0.001), ICC3 0.66 (p < 0.001, 95% confidence interval (CI) 0.53-0.73). Among individuals prescribed anticholinergics, 33% were robust, 44% were prefrail, and 23% were frail. All five tools predicted prefrail and frail status (p < 0.05) with low model misclassification rates for frail individuals (AUC range 0.78-0.85). CONCLUSION: Anticholinergic burden tools evaluated in this cohort of low-income African American older adults were highly correlated and predicted prefrail and frail status. Findings indicate that clinicians can select the appropriate instrument for the clinic setting and research question while maintaining confidence that all five tools will produce reliable results. Future anticholinergic research is needed to unravel the association between interventions such as deprescribing on incident frailty in longitudinal data.

QuickStroop Predicts Time to Development of Overt Hepatic Encephalopathy and Related Hospitalizations in Patients With Cirrhosis.

Cirrhosis-related neurocognitive impairment caused by covert or minimal hepatic encephalopathy (CHE) affects psychosocial function, increases risk of overt hepatic encephalopathy (OHE) development, and worsens survival.1,2 However, detection in clinical practice is challenging.2 One modality used for screening and prediction of outcomes related to cirrhosis is the EncephalApp Stroop, but it can require up to 10 minutes. Furthermore, the assessment comprises of distinct stages of difficulty, with an easier "Off" stage and a more challenging "On" stage.3 To alleviate these concerns, QuickStroop, which takes <1 minute, was developed. This uses only the first 2 runs of the Off stage of the EncephalApp Stroop, where number signs presented in red, green, or blue need to be matched quickly to their respective colors.4 A prior study showed these versions were comparable cross-sectionally to diagnose CHE.4 However, the utility of QuickStroop to predict cirrhosis-related outcomes is unclear.5-7 Our aim was to determine the ability of QuickStroop to determine time to development of OHE and OHE-related hospitalizations, all-cause hospitalizations, and death in outpatients with cirrhosis.

Long-term outcome analysis of Y90 radioembolization in hepatocellular carcinoma.

Background: Yttrium-90 (Y90) radioembolization is a catheter-based therapy for hepatocellular carcinoma (HCC). Multiple trials have evaluated the efficacy of Y90 in HCC; however, few have assessed long-term hepatic function. This study aimed to evaluate a clinical real-world experience of Y90 effectiveness and long-term impact on hepatic function. Methods: A single-center retrospective chart review was performed for patients with Child-Pugh (CP) class A or B who received Y90 for primary HCC between 2008 and 2016. Model for end-stage liver disease (MELD) and CP scores were calculated on the day of treatment and 1, 3, 6, 12, and 24 months post-procedure. Results: Of the 134 patients included, the mean age was 60 years old and median overall survival (OS) from date of diagnosis was 28 months [95% confidence interval (CI): 22.21-38.05]. Patients with CP class A (85%) had a median progression-free survival (PFS) of 3 months (95% CI: 2.99-5.55) and median OS of 17 months (95% CI: 9.59-23.10) from date of Y90 treatment compared to a median PFS of 4 months (95% CI: 2.07-8.28) and OS of 8 months (95% CI: 4.60-15.64) for patients with CP class B. MELD scores were significantly higher post-treatment than pre-treatment, with significant recovery at 24 months. No significant differences were seen between cancer stage and OS, while PFS and cancer stage did show difference between cancer stage 1 and 3 with longer median PFS seen in stage 1. Conclusions: While our study supports the literature for OS in Y90-treated patients, we found a shorter PFS in this population. This may reflect the differences between the utilization of RECIST in clinical trials and clinical radiology practice in determining progression. Significant factors associated with OS were age, MELD, CP scores and portal vein thrombosis (PVT). For PFS, CP score and stage at diagnosis were significant. Increasing MELD scores over time likely reflected a combination of radioembolization-induced liver disease, liver decompensation or progression of HCC. The downtrend at 24 months is likely due to long term survivors with significant benefit from therapy with no long-term complications from Y90.

Study protocol for the Mindful Moms Study: A randomized controlled trial evaluating a mindful movement intervention for marginalized pregnant people experiencing depression.

More than 1 in 5 pregnant people in the United States experience depressive symptoms. Although treatments exist, many people remain under- or un-treated due to concerns about stigma, side effects, and costs of medications or psychotherapy, particularly those who are marginalized (defined as those who are minoritized, low-income, or with low-educational attainment). Further, the standard depression treatments do not address social connectedness, which is a potentially modifiable factor involved in depressive symptom etiology. This protocol presents the rationale, design, and status of the two-arm longitudinal parallel group randomized controlled trial - the Mindful Moms Study - which aims to evaluate the effects and mechanisms of a group-based mindful physical activity (yoga) intervention in marginalized pregnant people with depressive symptoms (n = 200) compared to a prenatal education control group. The primary aim is to evaluate effects of group assignment on depressive symptom severity, anxiety, and perceived stress over time from baseline to six weeks postpartum. Secondary aims include understanding the role of social connectedness as a moderator of the effects and to identify genome-wide DNA methylation patterns associated with depressive symptoms and perceived social connectedness at postpartum. A focus on adequate symptom management through non-pharmacologic, accessible therapies that address social connectedness during pregnancy in marginalized women is an urgent clinical and research priority. The successful completion of this study will provide important insights into social connectedness as a mechanism to decrease depressive symptoms in a largely understudied population. Trial registration: NCT04886856.

Impact of the COVID-19 Pandemic on a Clinical Trial: A Quantitative Report on Study Engagement and Strategies.

INTRODUCTION: The COVID-19 pandemic impacted clinical research worldwide potentially altering research findings. The study purpose was to measure the effect of the pandemic on recruitment, retention, assessment, and intervention completion rates. METHODS: Enrollment and participation data from a clinical trial evaluating efficacy of a physical therapy intervention for high-risk preterm infants were compared across 3 pandemic periods (February 2019 through November 2021). RESULTS: Recruitment, retention, assessment, and intervention completion rates were lowest during the peak pandemic period. CONCLUSIONS: In compliance with the Human Subjects Review Board, and for the participants' and staff safety, transition from in-person to telehealth or hybrid visits was required to continue this longitudinal study. Despite the negative effect of the pandemic, parental resilience and commitment to the study was clear. Flexibility, quick action, dedication, and efficiency of the research team were key elements enabling study continuation with successful transition to telehealth assessments/interventions during the peak pandemic period.

Factors Influencing Receipt and Type of Therapy Services in the NICU.

Understanding the type and frequency of current neonatal intensive care unit (NICU) therapy services and predictors of referral for therapy services is a crucial first step to supporting positive long-term outcomes in very preterm infants. This study enrolled 83 very preterm infants (<32 weeks, gestational age mean 26.5 ± 2.0 weeks; 38 male) from a longitudinal clinical trial. Race, neonatal medical index, neuroimaging, and frequency of therapy sessions were extracted from medical records. The Test of Infant Motor Performance and the General Movement Assessment were administered. Average weekly sessions of occupational therapy, physical therapy, and speech therapy were significantly different by type, but the magnitude and direction of the difference depended upon the discharge week. Infants at high risk for cerebral palsy based on their baseline General Movements Assessment scores received more therapy sessions than infants at low risk for cerebral palsy. Baseline General Movements Assessment was related to the mean number of occupational therapy sessions but not physical therapy or speech therapy sessions. Neonatal Medical Index scores and Test of Infant Motor Performance scores were not predictive of combined therapy services. Medical and developmental risk factors, as well as outcomes from therapy assessments, should be the basis for referral for therapy services in the neonatal intensive care unit.

Global disparities in mortality and liver transplantation in hospitalised patients with cirrhosis: a prospective cohort study for the CLEARED Consortium.

BACKGROUND: Cirrhosis, the end result of liver injury, has high mortality globally. The effect of country-level income on mortality from cirrhosis is unclear. We aimed to assess predictors of death in inpatients with cirrhosis using a global consortium focusing on cirrhosis-related and access-related variables. METHODS: In this prospective observational cohort study, the CLEARED Consortium followed up inpatients with cirrhosis at 90 tertiary care hospitals in 25 countries across six continents. Consecutive patients older than 18 years who were admitted non-electively, without COVID-19 or advanced hepatocellular carcinoma, were enrolled. We ensured equitable participation by limiting enrolment to a maximum of 50 patients per site. Data were collected from patients and their medical records, and included demographic characteristics; country; disease severity (MELD-Na score); cirrhosis cause; medications used; reasons for admission; transplantation listing; cirrhosis-related history in the past 6 months; and clinical course and management while hospitalised and for 30 days post discharge. Primary outcomes were death and receipt of liver transplant during index hospitalisation or within 30 days post discharge. Sites were surveyed regarding availability of and access to diagnostic and treatment services. Outcomes were compared by country income level of participating sites, defined according to World Bank income classifications (high-income countries [HICs], upper-middle-income countries [UMICs], and low-income or lower-middle-income countries [LICs or LMICs]). Multivariable models controlling for demographic variables, disease cause, and disease severity were used to analyse the odds of each outcome associated with variables of interest. FINDINGS: Patients were recruited between Nov 5, 2021, and Aug 31, 2022. Complete inpatient data were obtained for 3884 patients (mean age 55·9 years [SD 13·3]; 2493 (64·2%) men and 1391 (35·8%) women; 1413 [36·4%] from HICs, 1757 [45·2%] from UMICs, and 714 [18·4%] from LICs or LMICs), with 410 lost to follow-up within 30 days after hospital discharge. The number of patients who died while hospitalised was 110 (7·8%) of 1413 in HICs, 182 (10·4%) of 1757 in UMICs, and 158 (22·1%) of 714 in LICs and LMICs (p<0·0001), and within 30 days post discharge these values were 179 (14·4%) of 1244 in HICs, 267 (17·2%) of 1556 in UMICs, and 204 (30·3%) of 674 in LICs and LMICs (p<0·0001). Compared with patients from HICs, increased risk of death during hospitalisation was found for patients from UMICs (adjusted odds ratio [aOR] 2·14 [95% CI 1·61-2·84]) and from LICs or LMICs (2·54 [1·82-3·54]), in addition to increased risk of death within 30 days post discharge (1·95 [1·44-2·65] in UMICs and 1·84 [1·24-2·72] in LICs or LMICs). Receipt of a liver transplant was recorded in 59 (4·2%) of 1413 patients from HICs, 28 (1·6%) of 1757 from UMICs (aOR 0·41 [95% CI 0·24-0·69] vs HICs), and 14 (2·0%) of 714 from LICs and LMICs (0·21 [0·10-0·41] vs HICs) during index hospitalisation (p<0·0001), and in 105 (9·2%) of 1137 patients from HICs, 55 (4·0%) of 1372 from UMICs (0·58 [0·39-0·85] vs HICs), and 16 (3·1%) of 509 from LICs or LMICs (0·21 [0·11-0·40] vs HICs) by 30 days post discharge (p<0·0001). Site survey results showed that access to important medications (rifaximin, albumin, and terlipressin) and interventions (emergency endoscopy, liver transplantation, intensive care, and palliative care) varied geographically. INTERPRETATION: Inpatients with cirrhosis in LICs, LMICs, or UMICs have significantly higher mortality than inpatients in HICs independent of medical risk factors, and this might be due to disparities in access to essential diagnostic and treatment services. These results should encourage researchers and policy makers to consider access to services and medications when evaluating cirrhosis-related outcomes.

Depressive-like Behavior Is Accompanied by Prefrontal Cortical Innate Immune Fatigue and Dendritic Spine Losses after HIV-1 Tat and Morphine Exposure.

Opioid use disorder (OUD) and HIV are comorbid epidemics that can increase depression. HIV and the viral protein Tat can directly induce neuronal injury within reward and emotionality brain circuitry, including the prefrontal cortex (PFC). Such damage involves both excitotoxic mechanisms and more indirect pathways through neuroinflammation, both of which can be worsened by opioid co-exposure. To assess whether excitotoxicity and/or neuroinflammation might drive depressive behaviors in persons infected with HIV (PWH) and those who use opioids, male mice were exposed to HIV-1 Tat for eight weeks, given escalating doses of morphine during the last two weeks, and assessed for depressive-like behavior. Tat expression decreased sucrose consumption and adaptability, whereas morphine administration increased chow consumption and exacerbated Tat-induced decreases in nesting and burrowing-activities associated with well-being. Across all treatment groups, depressive-like behavior correlated with increased proinflammatory cytokines in the PFC. Nevertheless, supporting the theory that innate immune responses adapt to chronic Tat exposure, most proinflammatory cytokines were unaffected by Tat or morphine. Further, Tat increased PFC levels of the anti-inflammatory cytokine IL-10, which were exacerbated by morphine administration. Tat, but not morphine, decreased dendritic spine density on layer V pyramidal neurons in the anterior cingulate. Together, our findings suggest that HIV-1 Tat and morphine differentially induce depressive-like behaviors associated with increased neuroinflammation, synaptic losses, and immune fatigue within the PFC.

Admission Serum Metabolites and Thyroxine Predict Advanced Hepatic Encephalopathy in a Multicenter Inpatient Cirrhosis Cohort.

BACKGROUND & AIMS: Grades 3 to 4 hepatic encephalopathy (advanced HE), also termed brain failure, is an organ failure that defines acute-on-chronic liver failure. It is associated with poor outcomes in cirrhosis but cannot be predicted accurately. We aimed to determine the admission metabolomic biomarkers able to predict the development of advanced HE with subsequent validation. METHODS: Prospective inpatient cirrhosis cohorts (multicenter and 2-center validation) without brain failure underwent admission serum collection and inpatient follow-up evaluation. Serum metabolomics were analyzed to predict brain failure on random forest analysis and logistic regression. A separate validation cohort also was recruited. RESULTS: The multicenter cohort included 602 patients, of whom 144 developed brain failure (105 only brain failure) 3 days after admission. Unadjusted random forest analysis showed that higher admission microbially derived metabolites and lower isoleucine, thyroxine, and lysophospholipids were associated with brain failure development (area under the curve, 0.87 all; 0.90 brain failure only). Logistic regression area under the curve with only clinical variables significantly improved with metabolites (95% CI 0.65-0.75; P = .005). Four metabolites that significantly added to brain failure prediction were low thyroxine and maltose and high methyl-4-hydroxybenzoate sulfate and 3-4 dihydroxy butyrate. Thyroxine alone also significantly added to the model (P = .05). The validation cohort including 81 prospectively enrolled patients, of whom 11 developed brain failure. Admission hospital laboratory thyroxine levels predicted brain failure development despite controlling for clinical variables with high specificity. CONCLUSIONS: In a multicenter inpatient cohort, admission serum metabolites, including thyroxine, predicted advanced HE development independent of clinical factors. Admission low local laboratory thyroxine levels were validated as a predictor of advanced HE development in a separate cohort.

QuickStroop, a Shortened Version of EncephalApp, Detects Covert Hepatic Encephalopathy With Similar Accuracy Within One Minute.

BACKGROUND & AIMS: Covert hepatic encephalopathy (CHE) is associated with poor outcomes but is often not diagnosed because of the time requirement. Psychometric hepatic encephalopathy score (PHES) is the gold standard against which EncephalApp Stroop has been validated. However, EncephalApp (5 runs each in "Off" and "On" state) can take up to 10 minutes. This study sought to define the smallest number of EncephalApp runs needed for comparable accuracy to the total EncephalApp using CHE on PHES as gold standard. METHODS: A derivation and a validation cohort of outpatients with cirrhosis who underwent PHES (gold standard) and total EncephalApp was recruited. Data were analyzed for individual runs versus total EncephalApp time versus PHES-CHE. The derivation cohort (n = 398) was split into training (n = 299) and test (n = 99) sets. From the training data set a regression model was created with age, gender, education, and various sums of the "Off" settings. After this, a K-fold cross-validation on the test dataset was performed for both total EncephalApp time and individual Off runs and for the validation cohort. RESULTS: In both cohorts, Off runs 1 + 2 had statistically similar area under the receiver operating curve and P value to the total EncephalApp for PHES-CHE prediction. The adjusted (age, gender, education) regression formula from the derivation cohort showed an accuracy of 84% to diagnose PHES-CHE in the validation cohort. Time for CHE diagnosis decreased from 203.7 (67.82) to 36.8 (11.25) seconds in the derivation and from 178.2 (46.19) to 32.9 (9.94) seconds in the validation cohort. CONCLUSIONS: QuickStroop, which is completed within 1 minute, gives an equivalent ability to predict CHE on the gold standard compared with the entire EncephalApp time.

Role of Oral Health, Frailty, and Minimal Hepatic Encephalopathy in the Risk of Hospitalization: A Prospective Multi-Center Cohort of Outpatients With Cirrhosis.

BACKGROUND & AIMS: Hospitalizations are a sentinel event in cirrhosis; however, the changing demographics in patients with cirrhosis require updated hospitalization prediction models. Periodontitis is a risk factor for liver disease and potentially progression. The aim of this study was to determine factors, including poor oral health, associated with 3-month hospitalizations in a multi-center cohort of outpatients with cirrhosis. METHODS: North American Consortium for Study of End-stage Liver Disease (NACSELD-3), a new study cohort, recruits outpatients with cirrhosis. Cirrhosis details, demographics, minimal hepatic encephalopathy (MHE), frailty, and comorbid conditions including oral health were collected. All patients were followed for 3 months for nonelective hospitalizations. Multi-variable models were created for this outcome using demographics, cirrhosis details, oral health, MHE, frailty, and comorbid conditions with K-fold internal validation using 25%/75% split. RESULTS: A total of 442 outpatients (70% men; 37% compensated; Model for End-stage Liver Disease-Sodium, 12; 42% ascites; and 33% prior HE) were included. MHE was found in 70%, frailty in 10%; and both in 8%. In terms of oral health, 15% were edentulous and 10% had prior periodontitis. Regarding 3-month hospitalizations, 14% were admitted for mostly liver-related reasons. These patients were more likely to be decompensated with higher cirrhosis complications, MHE, frailty and periodontitis history. Multi-variable analysis showed prior periodontitis (P = .026), composite MHE + frailty score (P = .0016), ascites (P = .004), prior HE (P = .008), and hydrothorax (P = .004) were associated with admissions using the training and validation subsets. CONCLUSIONS: In a contemporaneous, prospective, multi-center cohort study in outpatients with cirrhosis, poor oral health is significantly associated with 3-month hospitalizations independent of portal hypertensive complications, MHE, and frailty. Potential strategies to reduce hospitalizations should consider oral evaluation in addition to MHE and frailty assessment in practice pathways.

Association of serum metabolites and gut microbiota at hospital admission with nosocomial infection development in patients with cirrhosis.

Cirrhosis is complicated by a high rate of nosocomial infections (NIs), which result in poor outcomes and are challenging to predict using clinical variables alone. Our aim was to determine predictors of NI using admission serum metabolomics and gut microbiota in inpatients with cirrhosis. In this multicenter inpatient cirrhosis study, serum was collected on admission for liquid chromatography-mass spectrometry metabolomics, and a subset provided stool for 16SrRNA analysis. Hospital course, including NI development and death, were analyzed. Metabolomic analysis using analysis of covariance (ANCOVA) (demographics, Model for End-Stage Liver Disease [MELD] admission score, white blood count [WBC], rifaximin, and infection status adjusted) and random forest analyses for NI development were performed. Additional values of serum metabolites over clinical variables toward NI were evaluated using logistic regression. Stool microbiota and metabolomic correlations were compared in patients with and without NI development. A total of 602 patients (231 infection admissions) were included; 101 (17%) developed NIs, which resulted in worse inpatient outcomes, including intensive care unit transfer, organ failure, and death. A total of 127 patients also gave stool samples, and 20 of these patients developed NIs. The most common NIs were spontaneous bacterial peritonitis followed by urinary tract infection, Clostridioides difficile, and pneumonia. A total of 247 metabolites were significantly altered on ANCOVA. Higher MELD scores (odds ratio, 1.05; p < 0.0001), admission infection (odds ratio, 3.54; p < 0.0001), and admission WBC (odds ratio, 1.05; p = 0.04) predicted NI (area under the curve, 0.74), which increased to 0.77 (p = 0.05) with lower 1-linolenoyl-glycerolphosphocholine (GPC) and 1-stearoyl-GPC and higher N-acetyltryptophan and N-acetyl isoputreanine. Commensal microbiota were lower and pathobionts were higher in those who developed NIs. Microbial-metabolite correlation networks were complex and dense in patients with NIs, especially sub-networks centered on Ruminococcaceae and Pseudomonadaceae. NIs are common and associated with poor outcomes in cirrhosis. Admission gut microbiota in patients with NIs showed higher pathobionts and lower commensal microbiota. Microbial-metabolomic correlations were more complex, dense, and homogeneous among those who developed NIs, indicating greater linkage strength. Serum metabolites and gut microbiota on admission are associated with NI development in cirrhosis.

Coffee and energy drink use patterns in college freshmen: associations with adverse health behaviors and risk factors.

BACKGROUND: Public health concern over college students mixing caffeine-containing energy drinks (EDs) and alcohol has contributed to an array of ED-focused research studies. One review found consistent associations between ED use and heavy/problem drinking as well as other drug use and risky behaviors (Nutr Rev 72:87-97, 2014). The extent to which similar patterns exist for other sources of caffeine is not known. The present study examined associations between coffee and ED consumption and alcohol, tobacco and other drug use; alcohol use problems; and parental substance abuse and mental health problems in a sample of college freshmen. METHODS: Subjects were N = 1986 freshmen at an urban university who completed an on-line survey about demographics; caffeine; alcohol, tobacco and other drug use; and family history. The sample was 61% female and 53% White. Chi-square analyses and multivariable binary or ordinal logistic regression were used to compare substance use, problem alcohol behavior, and familial risk measures across 3 caffeine use groups: ED (with or without Coffee) (ED + Co; N = 350); Coffee but no ED (Co; N = 761); and neither coffee nor ED (NoCE; N = 875) use. RESULTS: After adjusting for gender and race, the 3 caffeine use groups differed on 8 of 9 symptoms for alcohol dependence. In all cases, the ED + Co group was most likely to endorse the symptom, followed by the Co group and finally the NoCE group (all p < .002). A similar pattern was found for: use 6+ times of 5 other classes of drugs (all p < .05); extent of personal and peer smoking (all p < .001); and paternal problems with alcohol, drugs and anxiety/depression as well as maternal alcohol problems and depression/anxiety (p < .04). CONCLUSIONS: The response pattern was ubiquitous, with ED + Co most likely, Co intermediate, and NoCE least likely to endorse a broad range of substance use, problem alcohol behaviors, and familial risk factors. The finding that the Co group differed from both the ED + Co and NoCE groups on 8 measures and from the NoCE group on one additional measure underscores the importance of looking at coffee in addition to EDs when considering associations between caffeine and other risky behaviors.

The Prediction of In-Hospital Mortality in Decompensated Cirrhosis with Acute-on-Chronic Liver Failure.

Acute-on-chronic liver failure (ACLF) is a condition in cirrhosis associated with organ failure (OF) and high short-term mortality. Both the European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) and North American Consortium for the Study of End-Stage Liver Disease (NACSELD) ACLF definitions have been shown to predict ACLF prognosis. The aim of this study was to compare the ability of the EASL-CLIF versus NACSELD systems over baseline clinical and laboratory parameters in the prediction of in-hospital mortality in admitted patients with decompensated cirrhosis. Five NACSELD centers prospectively collected data to calculate EASL-CLIF and NACSELD-ACLF scores for admitted patients with cirrhosis who were followed for the development of OF, hospital course, and survival. Both the number of OFs and the ACLF grade or presence were used to determine the impact of NACSELD versus EASL-CLIF definitions of ACLF above baseline parameters on in-hospital mortality. A total of 1031 patients with decompensated cirrhosis (age, 57 ± 11 years; male, 66%; Child-Pugh-Turcotte score, 10 ± 2; Model for End-Stage Liver Disease [MELD] score, 20 ± 8) were enrolled. Renal failure prevalence (28% versus 9%, P < 0.001) was more common using the EASL-CLIF versus NACSELD definition, but the prevalence rates for brain, circulatory, and respiratory failures were similar. Baseline parameters including age, white cell count on admission, and MELD score reasonably predicted in-hospital mortality (area under the curve, 0.76). The addition of number of OFs according to either system did not improve the predictive power of the baseline parameters for in-hospital mortality, but the presence of NACSELD-ACLF did. However, neither system was better than baseline parameters in the prediction of 30- or 90-day outcomes. The presence of NACSELD-ACLF is equally effective as the EASL-CLIF ACLF grade, and better than baseline parameters in the prediction of in-hospital mortality in patients with cirrhosis, but not superior in the prediction of longer-term 30- or 90-day outcomes.

Adaptations to the RVA Breathes clinical trial due to the COVID-19 pandemic.

RVA Breathes, a community program to improve asthma management and care coordination among children living in a low-income, urban area, is being evaluated in a randomized clinical trial. In March 2020, RVA Breathes was converted to a remote program due to the COVID-19 pandemic; this report provides an update on the modifications made to the RVA Breathes trial. Additionally, given that families in the program have been disproportionally impacted by both COVID-19 and significant social unrest at both the local and national level, strategies used to enroll and engage families in the trial who bore disproportionately high burdens during this time period are outlined. Remote sessions (telephone or video) for families enrolled in the program prior to the onset of COVID-19 began in April 2020; enrollment of new families began remotely in July 2020 using adapted consent procedures. Baseline, intervention, and follow-up sessions were delivered either via the telephone or video depending upon family preference. Strategies were implemented to engage caregivers and children in completing measures over the telephone or video versus in person. Tangible intervention materials and participant payments were dropped off at family homes using contactless procedures. Our team was able to adapt and safely continue a large, community-based clinical trial, despite the increased health risks and social isolation mandates from the pandemic, by transitioning to a remote format. Challenges remain in determining whether RVA Breathes as a remote program has had the same impact on child asthma as the face-to-face interventions that comprised its original format.
