Clinical outcomes in patients with heart failure with and without cirrhosis: an analysis from the national inpatient sample.
Outcomes of heart failure (HF) hospitalization are driven by the presence or absence of comorbid conditions. Cirrhosis is associated with worse outcomes in patients with HF, and both HF and cirrhosis are associated with worse renal outcomes. Using a nationally representative sample we describe inpatient outcomes of all-cause mortality and length of stay (LOS) among patients with and without cirrhosis hospitalized for decompensated with HF. We conducted a cross sectional analysis using Nationwide Inpatient Sample (2010-2014) data including patients hospitalized for decompensated HF, with or without cirrhosis. We calculated the adjusted odds of all-cause mortality, acute kidney injury (AKI), and target LOS after adjusting for potential confounders. Out of the 2,487,445 hospitalized for decompensated HF 39,950 had cirrhosis of which majority (75.1%) were non-alcoholic cirrhosis. Patients with comorbid cirrhosis were more likely to die (OR, 1.26; 95% CI, 1.11 to 1.43) and develop AKI (OR, 1.26; 95% CI, 1.16 to 1.36) as compared to those without cirrhosis. Underlying CKD was associated with a greater odds of AKI (OR, 4.99; 95% CI, 4.90 to 5.08), and the presence of cirrhosis amplified this risk (OR, 6.03; 95% CI, 5.59 to 6.51). There was approximately a 40% decrease in the relative odds of lower HF hospitalization length of stay among those with both CKD and cirrhosis, relative to those without either comorbidities. Cirrhosis in patients with hospitalizations for decompensated HF is associated with higher odds of mortality, decreased likelihood of discharge by the targeted LOS, and AKI. Among patients with HF the presence of cirrhosis increases the risk of AKI, which in turn is associated with poor clinical outcomes
Association Between Cirrhosis and 30-Day Rehospitalization After Index Hospitalization for Heart Failure.
There are limited data on clinical outcomes in patients re-admitted with decompensated heart failure (HF) with concomitant liver cirrhosis. We conducted a cross sectional analysis of the Nationwide Readmissions Database (NRD) years 2010 thru 2012. An Index admission was defined as a hospitalization for decompensated heart failure among persons aged ≥ 18 years with an alive discharge status. The main outcome was 30 - day all-cause rehospitalization. Survey logistic regression provided the unadjusted and adjusted odds of 30 - day rehospitalization among persons with and without cirrhosis, accounting for age, gender, kidney dysfunction and other comorbidities. There were 2,147,363 heart failure (HF) hospitalizations among which 26,156 (1.2%) had comorbid cirrhosis. Patients with cirrhosis were more likely to have a diagnosis of acute kidney injury (AKI) during their index hospitalization (18.4% vs 15.2%). There were 469,111 (21.9%) patients with readmission within 30 - days. The adjusted odds of a 30 - day readmission was significantly higher among patients with cirrhosis compared to without after adjusting for comorbid conditions (adjusted Odds Ratio [aOR], 1.3; 95% Confidence Interval [CI}: 1.2 to 1.4). The relative risk of 30 - day readmission among those with cirrhosis but without renal disease (aOR, 1.3; 95% CI: 1.3 to 1.3) was lower than those with both cirrhosis and renal disease (aOR, 1.8; 95% CI: 1.6 to 2.0) when compared to persons without either comorbidities. Risk of 30 - day rehospitalization was significantly higher among patients with heart failure and underlying cirrhosis. Concurrent renal dysfunction among patients with cirrhosis hospitalized for decompensated HF was associated with a greater odds of rehospitalization
Invasive hemodynamic parameters in patients with hepatorenal syndrome.
Background: Hepatorenal syndrome (HRS), a form of kidney dysfunction frequent in cirrhotic patients, is characterized by low filling pressures and impaired kidney perfusion due to peripheral vasodilation and reduced effective circulatory volume. Cardiorenal syndrome (CRS), driven by renal venous hypertension and elevated filling pressures, is a separate cause of kidney dysfunction in cirrhotic patients. The two entities, however, have similar clinical phenotypes. To date, limited invasive hemodynamic data are available to help distinguish the primary forces behind worsened kidney function in cirrhotic patients.
Objective: Our aim was to analyze invasive hemodynamic profiles and kidney outcomes in patients with cirrhosis who met criteria for HRS.
Methods: We conducted a single center retrospective study among cirrhotic patients with worsening kidney function admitted for liver transplant evaluation between 2010 and 2020. All met accepted criteria for HRS and underwent concurrent right heart catheterization (RHC).
Results: 127 subjects were included. 79 had right atrial pressure \u3e10 mmHg, 79 had wedge pressure \u3e15 mmHg, and 68 had both. All patients with elevated wedge pressure were switched from volume loading to diuretics resulting in significant reductions between admission and post diuresis creatinine values (2.0 [IQR 1.5-2.8] vs 1.5 [IQR 1.2-2.2]; p = 0.003).
Conclusion: 62% of patients diagnosed with HRS by clinical criteria have elevated filling pressures. Improvement of renal function after diuresis suggests the presence of CRS physiology in these patients. Invasive hemodynamic data profiling can lead to meaningful change in management of cirrhotic patients with worsened kidney function, guiding appropriate therapies based on filling pressures
Angiotensin converting enzyme inhibitors and angiotensin receptor blockers in acute heart failure: invasive hemodynamic parameters and clinical outcomes.
There are limited data regarding the use of angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEi/ARBs) in acute heart failure (AHF). The purpose is to determine the patterns of ACEi/ARB use at the time of admission and discharge in relation to invasive hemodynamic data, mortality, and heart failure (HF) readmissions. This is a retrospective single-center study in patients with AHF who underwent right heart catheterization between January 2010 and December 2016. Patients on dialysis, evidence of shock, or incomplete follow up were excluded. Multivariate logistic regression analysis was used to analyze the factors associated with continuation of ACEi/ARB use on discharge and its relation to mortality and HF readmissions. The final sample was 626 patients. Patients on ACEi/ARB on admission were most likely continued on discharge. The most common reasons for stopping ACEi/ARB were worsening renal function (WRF), hypotension, and hyperkalemia. Patients with ACEi/ARB use on admission had a significantly higher systemic vascular resistance (SVR) and mean arterial pressure (MAP), but lower cardiac index (CI). Patients with RA pressures above the median received less ACEi/ARB (P = 0.025) and had significantly higher inpatient mortality (P = 0.048). After multivariate logistic regression, ACEi/ARB use at admission was associated with less inpatient mortality; OR 0.32 95% CI (0.11 to 0.93), and this effect extended to the subgroup of patients with HFpEF. Patients discharged on ACEi/ARB had significantly less 6-month HF readmissions OR 0.69 95% CI (0.48 to 0.98). ACEi/ARB use on admission for AHF was associated with less inpatient mortality including in those with HFpEF

Implementing Routine HIV Testing: The Role of State Law
In September 2006, the Centers for Disease Control and Prevention (CDC) recommended routine HIV testing for all Americans aged 13–64, which would eliminate requirements for written consent and pretest counseling as previously required. However, this approach may conflict with state requirements concerning pretest counseling and informed consent for HIV testing. Our survey of state HIV testing laws demonstrates that the majority of states have HIV testing requirements that are inconsistent with the CDC's recommendations. Moreover, states that have recently amended their laws have not eased the requirements for pretest counseling and informed consent. The reasons for the persistence of these legal requirements must be understood to effect policy changes to increase HIV testing
First narrow-band search for continuous gravitational waves from known pulsars in advanced detector data
Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of
continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a
fully coherent search, based on matched filtering, which uses the position and rotational parameters
obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signalto-
noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch
between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have
been developed, allowing a fully coherent search for gravitational waves from known pulsars over a
fraction of a hertz and several spin-down values. In this paper we describe a narrow-band search of
11 pulsars using data from Advanced LIGO’s first observing run. Although we have found several initial
outliers, further studies show no significant evidence for the presence of a gravitational wave signal.
Finally, we have placed upper limits on the signal strain amplitude lower than the spin-down limit for 5 of
the 11 targets over the bands searched; in the case of J1813-1749 the spin-down limit has been beaten for
the first time. For an additional 3 targets, the median upper limit across the search bands is below the
spin-down limit. This is the most sensitive narrow-band search for continuous gravitational waves carried
out so far
Measurement of the cross-section and charge asymmetry of bosons produced in proton-proton collisions at TeV with the ATLAS detector
This paper presents measurements of the and cross-sections and the associated charge asymmetry as a
function of the absolute pseudorapidity of the decay muon. The data were
collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with
the ATLAS experiment at the LHC and correspond to a total integrated luminosity
of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements
varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the
1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured
with an uncertainty between 0.002 and 0.003. The results are compared with
predictions based on next-to-next-to-leading-order calculations with various
parton distribution functions and have the sensitivity to discriminate between
them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables,

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector
Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente
Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector
A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13 TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139 fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV
