INTRODUCTION/BACKGROUND:Even with the adequate use of diuretics and vasodilators, volume overload and congestion are the major causes of morbidity and mortality in patients hospitalized with acute heart failure (HF). We aim to evaluate the additive effect of tolvaptan on efficacy parameters as well as outcomes in hospitalized patients with HF. METHODS:We searched PubMed, EMBASE, Cochrane library, and Web of Science databases for randomized controlled trials that studied the effects of tolvaptan versus placebo in hospitalized patients with HF. Studies were included if they had any of the following endpoints: mortality, re-hospitalization, and in-hospital parameters like dyspnea relief, change in weight, sodium, and creatinine. RESULTS:The meta-analysis analyzed data from 14 studies involving 5945 patients. The follow up duration ranged from 30 days to 2 years. Between tolvaptan and placebo groups, there was no difference in mortality and rehospitalization. HF patients had a better dyspnea relief score (Likert score) in tolvaptan group and mean reduction in weight in the first 48 h (short-term). However, at 7 days (medium-term) the mean difference in weight was not significant. Serum sodium increased significantly in tolvaptan group. There was no difference in creatinine among the two groups. CONCLUSIONS:Our meta-analysis shows that tolvaptan helps in short-term symptomatic dyspnea relief and weight reduction, but there are no long term benefits including reduction in mortality and rehospitalization.

BACKGROUND:Prone positioning improves mortality in patients intubated with acute respiratory distress syndrome and has been proposed as a treatment for nonintubated patients with COVID-19 outside the ICU. However, there are substantial patient and operational barriers to prone positioning on acute floors. The objective of this project was to increase the frequency of prone positioning among acute care patients with COVID-19. METHODS:The researchers conducted a retrospective analysis of all adult patients admitted to the acute care floors with COVID-19 respiratory failure. A run chart was used to quantify the frequency of prone positioning over time. For the subset of patients assisted by a dedicated physical therapy team, oxygen before and after positioning was compared. The initiative consisted of four separate interventions: (1) nursing, physical therapy, physician, and patient education; (2) optimization of supply management and operations; (3) an acute care prone positioning team; and (4) electronic health record optimization. RESULTS:From March 9, 2020, to August 26, 2020, 176/875 (20.1%) patients were placed in prone position. Among these, 43 (24.4%) were placed in the prone position by the physical therapy team. Only 2/94 (2.1%) eligible patients admitted in the first two weeks of the pandemic were ever documented in prone position. After launching the initiative, weekly frequency peaked at 13/28 (46.4%). Mean oxygen saturation was 91% prior to prone positioning vs. 95.2% after (p < 0.001) in those positioned by physical therapy. CONCLUSION:A multidisciplinary quality improvement initiative increased frequency of prone positioning by proactively addressing barriers in knowledge, equipment, training, and information technology.

OBJECTIVES: We designed a prospective cohort study to systematically study patients with severe acute respiratory infection (SARI) and improve hospital preparedness (SARI-PREP). The goal of this project is to evaluate the natural history, prognostic biomarkers, and characteristics, including hospital stress, associated with SARI clinical outcomes and severity.
METHOD(S): In collaboration with the Society of Critical Care Medicine Discovery Research Network and the National Emerging Special Pathogen Training and Education Center (NETEC), SARIPREP is an ongoing, prospective, observational, multi-center cohort study of hospitalized patients with respiratory viral infections. We collected patient demographics, signs, symptoms, and medications; microbiology, imaging, and other diagnostics; mechanical ventilation, hospital procedures, and other interventions; and clinical outcomes. Hospital leadership completed a weekly hospital stress survey. Respiratory, blood, and urine biospecimens were collected from patients on days 0, 3, 7-14 after study enrollment and at hospital discharge. MEASUREMENTS AND MAIN RESULTS: SARI-PREP enrollment began on April 4, 2020 and currently includes 674 patients. Here we report results from the first 400 patients: 216 are from the University of Washington Hospitals, Seattle WA, 142 from New York University, New York NY and 42 from University of Southern California, Los Angeles, CA. Almost all tested positive for SARS-CoV-2 infection (n=397), whereas 3 patients tested positive for an alternative viral pathogen. The mean (+/-SD) age of the patients was 57+/-16 years; 72% were men, 62% were White, 14% were Asian, 12% were Black, and 31% were Hispanic. Most of the patients were admitted to the intensive care unit (96%). The median (interquartile range) hospital length of stay was 22 (9-46) days. Rates of invasive mechanical ventilation (72%) and renal replacement therapy (19%) were common and the rate of hospital mortality was 35%.
CONCLUSION(S): Initial SARI-PREP analysis indicates enrollment of a diverse population of hospitalized patients primarily with SARSCoV-2 infection. The demographics and clinical outcomes of our cohort mirror other large critically ill cohorts of COVID-19 patients. Results of a concomitant, weekly, hospital stress assessment are reported separately

Rescue/recovery workers who responded to the World Trade Center (WTC) attacks were exposed to known/suspected carcinogens. Studies have identified a trend toward an elevated risk of cutaneous melanoma in this population; however, few found significant increases. Furthermore, temporal aspects of the association have not been investigated. A total of 44,540 non-Hispanic White workers from the WTC Combined Rescue/Recovery Cohort were studied between March 12, 2002 and December 31, 2015. Cancer data were obtained through linkages with 13 state registries. Poisson regression was used to estimate hazard ratios and 95% confidence intervals using the New York State population as the reference; change points in hazard ratios were estimated using profile likelihood. We observed 247 incident cases of melanoma. No increase in incidence was detected during 2002-2004. From 2005 to 2015, the hazard ratio was 1.34 (95% confidence interval = 1.18-1.52). A dose‒response relationship was observed by arrival time at the WTC site. Risk was elevated just over 3 years after the attacks. Whereas WTC-related exposures to UVR or other agents might have contributed to this result, exposures other than those at the WTC site, enhanced medical surveillance, and lack of a control group with a similar proportion of rescue/recovery workers cannot be discounted. Our results support continued study of this population for melanoma.

Background: Older adults are the fastest growing subpopulation of patients with IBD, with approximately 15% diagnosed after 60 yearsof- age. Moreover, environmental exposures are thought to play a significant role in the development of older-onset IBD, given the lower genetic risk. Antibiotics have been associated with development of IBD in earlier generations, but the impact on IBD risk in older adults is uncertain. In this population-based cohort study, we assessed the impact of cumulative antibiotic use, the timing of antibiotic use, and the association between specific antibiotic classes and the development of older-onset IBD.
Method(s): Using Denmark nationwide registries, a cohort of residents >=60 years-of-age was established between 2000-2018. Information on exposure to antibiotics was retrieved from the Danish National Prescription Register. The number of courses of antibiotics (overall and specific classes) was considered a time-varying variable. The outcome, IBD, was identified based on ICD-10 codes in the Danish National Patient Register. Incidence rate ratios (IRRs) for IBD according to antibiotic use 1 to 5 years prior to IBD diagnosis were calculated by log-linear Poisson regression, and adjusted for age, sex, and calendar period.
Result(s): There were a total of 2,327,796 individuals aged 60 to 90 years included in the cohort, resulting in 22,670,484 personyears of follow-up. There were 10,773 new cases of ulcerative colitis (UC) and 3,825 new cases of Crohn's disease (CD). Overall, any antibiotic use was associated with an IRR for the development of IBD (IRR 1.64, 95%CI 1.58-1.71), with a positive dose response observed (1 course of antibiotics IRR 1.27 95%CI 1.21-1.33; 2 courses IRR 1.54 95%CI 1.46-1.63; 3 courses IRR 1.66 95%CI 1.67-1.77; 4 courses IRR 1.96 95%CI 1.83-2.09; 5+ courses IRR 2.35, 95%CI 2.24-2.47). A higher IRR was noted between the timeframe of 1-2 years before diagnosis (IRR 1.87, 95%CI 1.79-1.94) as compared to 2-5 years before diagnosis (IRR 1.42, 95%CI 1.36-1.48). Additionally, all antibiotic classes were associated with the development of IBD, including those not used to treat gastrointestinal infections. Antibiotics with the highest IRR were fluoroquinolones (IRR 2.27, 95%CI 2.08-2.48), nitroimidazoles (IRR 2.21, 95%CI 1.95-2.50), and macrolides (IRR 1.74, 95%CI 1.64-1.84). All results remained statistically significant when stratifying by UC and CD, with effect estimates slightly higher for CD as compared to UC.
Conclusion(s): Use of antibiotics, regardless of class studied, was associated with an increased risk of older-onset IBD. This risk was highest one to two years prior to diagnosis, but persisted even prior to that, suggesting a link between overall antibiotic use and development of older-onset IBD

The purpose of this consensus paper was to convene leaders and scholars from eight Expert Panels of the American Academy of Nursing and provide recommendations to advance nursing's roles and responsibility to ensure universal access to palliative care. On behalf of the Academy, these evidence-based recommendations will guide nurses, policy makers, government representatives, professional associations, and interdisciplinary and community partners to integrate palliative nursing services across health and social care settings. Through improved palliative nursing education, nurse-led research, nurse engagement in policy making, enhanced intersectoral partnerships with nursing, and an increased profile and visibility of palliative care nurses worldwide, nurses can assume leading roles in delivering high-quality palliative care globally, particularly for minoritized, marginalized, and other at-risk populations. Part II herein provides a summary of international responses and policy options that have sought to enhance universal palliative care and palliative nursing access to date. Additionally, we provide ten policy, education, research, and clinical practice recommendations based on the rationale and background information found in Part I. The consensus paper's 43 authors represent eight countries (Australia, Canada, England, Kenya, Lebanon, Liberia, South Africa, United States of America) and extensive international health experience, thus providing a global context for the subject matter.

INTRODUCTION: In patients with septic shock, the diastolic shock index (DSI), defined as the ratio of heart rate to diastolic blood pressure, has been shown to correlate with mortality. This is thought to be due to the underlying vasodilation and compensatory increases in heart rate. Although infection with COVID-19 frequently presents with sepsis-like symptoms and changes in blood pressure, the role of the DSI in these patients has not been studied. Our study sought to explore if the DSI may be similarly used in patients with COVID-19 to identify individuals with an elevated mortality risk.
METHOD(S): This was an IRB approved retrospective cohort study at a large academic hospital in New York City (NYC). Data was extracted from the electronic medical record by a trained analyst. Inclusion criteria were age 18 or older, admitted from the emergency department (ED) to the intensive care unit (ICU) between 01/01/2020 and 06/30/2020 with a positive test for COVID-19. We excluded individuals who were transferred from the floor or an outside hospital to the ICU and those with incomplete data. Our final cohort included 360 patients from NYC. The heart rate and diastolic blood pressure used to calculate the DSI were based on the first recorded vitals upon presentation to the ED. This was done in conjunction with a study at a University (ICESI) hospital in Cali, Colombia, with a combined cohort of 655 patients.
RESULT(S): The 28-day mortality rate for the combined study population was 24.9%. Descriptive statistics demonstrated a DSI of >= 1.6 was correlated with elevated 28 day mortality. Cox regression controlling for age, body mass index, respiratory rate, and systolic blood pressure, demonstrated that a DSI of >= 1.6 had a hazard ratio of 1.98 (p-value < 0.01, 95% CI 1.40-2.81).
CONCLUSION(S): In our study population, the DSI that correlated with an elevated risk of mortality was considerably lower than was seen in patients with septic shock, underscoring the physiologic differences between patients with septic shock and COVID-19. Further analysis of the data will be aimed at revealing the etiology of these differences

Introduction/UNASSIGNED:The purpose of this study was to assess the hospital quality measures and outcomes of operative hip fracture patients before and after implementation of an anesthesiology department protocol assigning decision for a preoperative transthoracic echocardiogram (TTE) to the hospitalist co-managing physician. Materials and Methods/UNASSIGNED:Demographics, injury details, hospital quality measures, and outcomes were reviewed for a consecutive series of patients presenting to our institution with an operative hip fracture. In May of 2019, a new protocol assigning the responsibility to indicate a patient for preoperative TTE was mandated to the co-managing hospitalist at the institution. Patients were split into pre-protocol and post-protocol cohorts. Linear regression modeling and comparative analyses were conducted with a Bonferroni adjusted alpha as appropriate. Results/UNASSIGNED:Between September 2015 and June 2021, 1002 patients presented to our institution and were diagnosed with a hip fracture. Patients in the post-protocol cohort were less likely to undergo a preoperative echocardiogram, experienced a shorter time (days) to surgery, shorter length of stay, an increase in amount of home discharges, and lower complication risks for urinary tract infection and acute blood loss anemia as compared to those in the pre-protocol cohort. There were no differences seen in inpatient or 30-day mortality. Multivariable linear regression demonstrated a patient's comorbidity profile (Charlson Comorbidity Index (CCI)) and their date of presentation (pre- or post-protocol), were both associated with (P<0.01) a patients' time to surgery. Conclusion/UNASSIGNED:A standardized preoperative work flow protocol regarding which physician evaluates and determines which patients require a preoperative TTE allows for a streamlined perioperative course for hip fracture patients. This allows for a shortened time to surgery and length of stay with an increase in home discharges and was associated with a reduced risk of common index hospitalization complications including UTI and anemia.
