Abstract: The first ($v_1^{\text{even}}$), second ($v_2$) and third ($v_3$) harmonic coefficients of the azimuthal particle distribution at mid-rapidity, are extracted for charged hadrons and studied as a function of transverse momentum ($p_T$) and mean charged particle multiplicity density $\langle \mathrm{N_{ch}} \rangle$ in U+U ($\roots =193$~GeV), Au+Au, Cu+Au, Cu+Cu, $d$+Au and $p$+Au collisions at $\roots = 200$~GeV with the STAR Detector. For the same $\langle \mathrm{N_{ch}} \rangle$, the $v_1^{\text{even}}$ and $v_3$ coefficients are observed to be independent of collision system, while $v_2$ exhibits such a scaling only when normalized by the initial-state eccentricity ($\varepsilon_2$). The data also show that $\ln(v_2/\varepsilon_2)$ scales linearly with $\langle \mathrm{N_{ch}} \rangle^{-1/3}$. These measurements provide insight into initial-geometry fluctuations and the role of viscous hydrodynamic attenuation on $v_n$ from small to large collision systems.

Abstract: © 2018 authors. Published by the American Physical Society. The transverse spin transfer from polarized protons to Λ and Λ hyperons is expected to provide sensitivity to the transversity distribution of the nucleon and to the transversely polarized fragmentation functions. We report the first measurement of the transverse spin transfer to Λ and Λ along the polarization direction of the fragmenting quark, DTT, in transversely polarized proton-proton collisions at s=200 GeV with the STAR detector at RHIC. The data correspond to an integrated luminosity of 18 pb-1 and cover the pseudorapidity range |η

Abstract: © 2018 The Author Fluctuations of conserved quantities such as baryon number, charge, and strangeness are sensitive to the correlation length of the hot and dense matter created in relativistic heavy-ion collisions and can be used to search for the QCD critical point. We report the first measurements of the moments of net-kaon multiplicity distributions in Au+Au collisions at sNN=7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV. The collision centrality and energy dependence of the mean (M), variance (σ2), skewness (S), and kurtosis (κ) for net-kaon multiplicity distributions as well as the ratio σ2/M and the products Sσ and κσ2are presented. Comparisons are made with Poisson and negative binomial baseline calculations as well as with UrQMD, a transport model (UrQMD) that does not include effects from the QCD critical point. Within current uncertainties, the net-kaon cumulant ratios appear to be monotonic as a function of collision energy.

Abstract: ©) between 40 and 60 MeV/c. The absolute cross section of the excess depends weakly on centrality, while those from a theoretical model calculation incorporating an in-medium broadened ρ spectral function and radiation from a quark gluon plasma or hadronic cocktail contributions increase dramatically with an increasing number of participant nucleons. Model calculations of photon-photon interactions generated by the initial projectile and target nuclei describe the observed excess yields but fail to reproduce the pT2 distributions. © 2018 authors.

Abstract: © 2018 New measurements of directed flow for charged hadrons, characterized by the Fourier coefficient v1, are presented for transverse momenta pT, and centrality intervals in Au+Au collisions recorded by the STAR experiment for the center-of-mass energy range sNN=7.7–200 GeV. The measurements underscore the importance of momentum conservation, and the characteristic dependencies on sNN, centrality and pT are consistent with the expectations of geometric fluctuations generated in the initial stages of the collision, acting in concert with a hydrodynamic-like expansion. The centrality and pT dependencies of v1even, as well as an observed similarity between its excitation function and that for v3, could serve as constraints for initial-state models. The v1even excitation function could also provide an important supplement to the flow measurements employed for precision extraction of the temperature dependence of the specific shear viscosity.

Abstract: © 2018 The Author Flow harmonics (vn) in the Fourier expansion of the azimuthal distribution of particles are widely used to quantify the anisotropy in particle emission in high-energy heavy-ion collisions. The symmetric cumulants, SC(m,n), are used to measure the correlations between different orders of flow harmonics. These correlations are used to constrain the initial conditions and the transport properties of the medium in theoretical models. In this Letter, we present the first measurements of the four-particle symmetric cumulants in Au+Au collisions at sNN=39 and 200 GeV from data collected by the STAR experiment at RHIC. We observe that v2and v3are anti-correlated in all centrality intervals with similar correlation strengths from 39 GeV Au+Au to 2.76 TeV Pb+Pb (measured by the ALICE experiment). The v2–v4correlation seems to be stronger at 39 GeV than at higher collision energies. The initial-stage anti-correlations between second and third order eccentricities are sufficient to describe the measured correlations between v2and v3. The best description of v2–v4correlations at sNN=200GeV is obtained with inclusion of the system's nonlinear response to initial eccentricities accompanied by the viscous effect with η/s>0.08. Theoretical calculations using different initial conditions, equations of state and viscous coefficients need to be further explored to extract η/s of the medium created at RHIC.

Abstract: © 2018 American Physical Society. We report measurements of the nuclear modification factor RCP for charged hadrons as well as identified π+(-), K+(-), and p(p) for Au+Au collision energies of sNN=7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe a clear high-pT net suppression in central collisions at 62.4 GeV for charged hadrons which evolves smoothly to a large net enhancement at lower energies. This trend is driven by the evolution of the pion spectra but is also very similar for the kaon spectra. While the magnitude of the proton RCP at high pT does depend on the collision energy, neither the proton nor the antiproton RCP at high pT exhibit net suppression at any energy. A study of how the binary collision-scaled high-pT yield evolves with centrality reveals a nonmonotonic shape that is consistent with the idea that jet quenching is increasing faster than the combined phenomena that lead to enhancement.

Abstract: © 2018 American Physical Society. An improved measurement of the HΛ3 lifetime is presented. In this paper, the mesonic decay modes HΛ3→He3 + π- and HΛ3→d+p+π- are used to reconstruct the HΛ3 from Au+Au collision data collected by the STAR collaboration at Relativistic Heavy Ion Collider (RHIC). A minimum χ2 estimation is used to determine the lifetime of τ=142-21+24(stat.)±29(syst.) ps. This lifetime is about 50% shorter than the lifetime τ=263±2 ps of a free Λ, indicating strong hyperon-nucleon interaction in the hypernucleus system. The branching ratios of the mesonic decay channels are also determined to satisfy B.R.(He3+π-)/(B.R.(He3+π-)+B.R.(d+p+π-))=0.32±0.05(stat.)±0.08(syst.). Our ratio result favors the assignment J(HΛ3)=12 over J(HΛ3)=32. These measurements will help to constrain models of hyperon-baryon interactions.

Abstract: The STAR Collaboration reports on the photoproduction of $\pi^+\pi^-$ pairs in gold-gold collisions at a center-of-mass energy of 200 GeV/nucleon-pair. These pion pairs are produced when a nearly-real photon emitted by one ion scatters from the other ion. We fit the $\pi^+\pi^-$ invariant mass spectrum with a combination of $\rho$ and $\omega$ resonances and a direct $\pi^+\pi^-$ continuum. This is the first observation of the $\omega$ in ultra-peripheral collisions, and the first measurement of $\rho-\omega$ interference at energies where photoproduction is dominated by Pomeron exchange. The $\omega$ amplitude is consistent with the measured $\gamma p\rightarrow \omega p$ cross section, a classical Glauber calculation and the $\omega\rightarrow\pi^+\pi^-$ branching ratio. The $\omega$ phase angle is similar to that observed at much lower energies, showing that the $\rho-\omega$ phase difference does not depend significantly on photon energy. The $\rho^0$ differential cross section $d\sigma/dt$ exhibits a clear diffraction pattern, compatible with scattering from a gold nucleus, with 2 minima visible. The positions of the diffractive minima agree better with the predictions of a quantum Glauber calculation that does not include nuclear shadowing than with a calculation that does include shadowing.

Abstract: © 2018 The Author(s) The transversity distribution, which describes transversely polarized quarks in transversely polarized nucleons, is a fundamental component of the spin structure of the nucleon, and is only loosely constrained by global fits to existing semi-inclusive deep inelastic scattering (SIDIS) data. In transversely polarized p↑+p collisions it can be accessed using transverse polarization dependent fragmentation functions which give rise to azimuthal correlations between the polarization of the struck parton and the final state scalar mesons. This letter reports on spin dependent di-hadron correlations measured by the STAR experiment. The new dataset corresponds to 25 pb−1 integrated luminosity of p↑+p collisions at s=500 GeV, an increase of more than a factor of ten compared to our previous measurement at s=200 GeV. Non-zero asymmetries sensitive to transversity are observed at a Q2 of several hundred GeV and are found to be consistent with the former measurement and a model calculation. We expect that these data will enable an extraction of transversity with comparable precision to current SIDIS datasets but at much higher momentum transfers where subleading effects are suppressed.

Abstract: © 2018 authors. Published by the American Physical Society. Rapidity-odd directed-flow measurements at midrapidity are presented for Λ, Λ, K±, Ks0, and φ at sNN=7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, and 200 GeV in Au+Au collisions recorded by the Solenoidal Tracker detector at the Relativistic Heavy Ion Collider. These measurements greatly expand the scope of data available to constrain models with differing prescriptions for the equation of state of quantum chromodynamics. Results show good sensitivity for testing a picture where flow is assumed to be imposed before hadron formation and the observed particles are assumed to form via coalescence of constituent quarks. The pattern of departure from a coalescence-inspired sum rule can be a valuable new tool for probing the collision dynamics.

Abstract: © 2017 American Physical Society. The STAR Collaboration reports on the photoproduction of π+π- pairs in gold-gold collisions at a center-of-mass energy of 200 GeV/nucleon-pair. These pion pairs are produced when a nearly real photon emitted by one ion scatters from the other ion. We fit the π+π- invariant-mass spectrum with a combination of ρ0 and ω resonances and a direct π+π- continuum. This is the first observation of the ω in ultraperipheral collisions, and the first measurement of ρ-ω interference at energies where photoproduction is dominated by Pomeron exchange. The ω amplitude is consistent with the measured γp→ωp cross section, a classical Glauber calculation, and the ω→π+π- branching ratio. The ω phase angle is similar to that observed at much lower energies, showing that the ρ-ω phase difference does not depend significantly on photon energy. The ρ0 differential cross section dσ/dt exhibits a clear diffraction pattern, compatible with scattering from a gold nucleus, with two minima visible. The positions of the diffractive minima agree better with the predictions of a quantum Glauber calculation that does not include nuclear shadowing than with a calculation that does include shadowing.

Abstract: © 2017 American Physical Society. We report the first dijet transverse momentum asymmetry measurements from Au+Au and pp collisions at RHIC. The two highest-energy back-to-back jets reconstructed from fragments with transverse momenta above 2 GeV/c display a significantly higher momentum imbalance in heavy-ion collisions than in the pp reference. When reexamined with correlated soft particles included, we observe that these dijets then exhibit a unique new feature - momentum balance is restored to that observed in pp for a jet resolution parameter of R=0.4, while rebalancing is not attained with a smaller value of R=0.2.

Abstract: © 2017 Macmillan Publishers Limited, part of Springer Nature. All rights reserved. The extreme energy densities generated by ultra-relativistic collisions between heavy atomic nuclei produce a state of matter that behaves surprisingly like a fluid, with exceptionally high temperature and low viscosity. Non-central collisions have angular momenta of the order of 1,000h, and the resulting fluid may have a strong vortical structure that must be understood to describe the fluid properly. The vortical structure is also of particular interest because the restoration of fundamental symmetries of quantum chromodynamics is expected to produce novel physical effects in the presence of strong vorticity. However, no experimental indications of fluid vorticity in heavy ion collisions have yet been found. Since vorticity represents a local rotational structure of the fluid, spin-orbit coupling can lead to preferential orientation of particle spins along the direction of rotation. Here we present measurements of an alignment between the global angular momentum of a non-central collision and the spin of emitted particles (in this case the collision occurs between gold nuclei and produces Λ baryons), revealing that the fluid produced in heavy ion collisions is the most vortical system so far observed. (At high energies, this fluid is a quark-gluon plasma.) We find that Λ and hyperons show a positive polarization of the order of a few per cent, consistent with some hydrodynamic predictions. (A hyperon is a particle composed of three quarks, at least one of which is a strange quark; the remainder are up and down quarks, found in protons and neutrons.) A previous measurement that reported a null result, that is, zero polarization, at higher collision energies is seen to be consistent with the trend of our observations, though with larger statistical uncertainties. These data provide experimental access to the vortical structure of the nearly ideal liquid created in a heavy ion collision and should prove valuable in the development of hydrodynamic models that quantitatively connect observations to the theory of the strong force.

Abstract: © 2017 American Physical Society. We present measurements of elliptic flow (v2) of electrons from the decays of heavy-flavor hadrons (eHF) by the STAR experiment. For Au+Au collisions at sNN=200 GeV we report v2, for transverse momentum (pT) between 0.2 and 7 GeV/c, using three methods: the event plane method (v2{EP}), two-particle correlations (v2{2}), and four-particle correlations (v2{4}). For Au+Au collisions at sNN=62.4 and 39 GeV we report v2{2} for pT

Abstract: © 2017 American Physical Society. We present the first measurement of charge-dependent directed flow in Cu+Au collisions at sNN=200 GeV. The results are presented as a function of the particle transverse momentum and pseudorapidity for different centralities. A finite difference between the directed flow of positive and negative charged particles is observed that qualitatively agrees with the expectations from the effects of the initial strong electric field between two colliding ions with different nuclear charges. The measured difference in directed flow is much smaller than that obtained from the parton-hadron-string-dynamics model, which suggests that most of the electric charges, i.e., quarks and antiquarks, have not yet been created during the lifetime of the strong electric field, which is of the order of, or less than, 1 fm/c.

Abstract: We present results from STAR's first dedicated fixed-target run conducted in 2015 with Au + Au collisions at root SNN = 4.5 GeV. Directed flow of protons and lambdas, elliptic flow of identified hadrons, HBT radii, as well as pion, Ks, and Lambda spectra are compared with previous results from the AGS. These results demonstrate that STAR has good event reconstruction and particle identification capabilities in the fixed-target configuration. The implications of these results on future STAR fixed-target runs are discussed.

Abstract: We report recent STAR results on searching for the Chiral Magnetic Effect via measurements of γ correlation and κ K parameter for charged hadrons and identified particle pairs ( ππ , pK , πK , pp , pπ ) in Au+Au collisions at 200 GeV. We compare the κ K parameters with expectations from the AMPT simulations. Sizable γ correlations for charged hadrons, using Time Projection Chamber event plane, in p+Au and d+Au 200 GeV have been observed, and the correlations in these small systems are reduced to near zero when the event planes from forward detectors are used. We will also present our results on the Chiral Magnetic Wave searches from p+Au collisions at 200 GeV.

Abstract: We present the first measurement of charge-dependent directed flow in Cu + Au collisions at root S-NN = 200 GeV. The results are presented as a function of the particle transverse momentum and pseudorapidity for different centralities. A finite difference between the directed flow of positive and negative charged particles is observed that qualitatively agrees with the expectations from the effects of the initial strong electric field between two colliding ions with different nuclear charges. The measured difference in directed flow is much smaller than that obtained from the parton-hadron-string-dynamics model, which suggests that most of the electric charges, i.e., quarks and antiquarks, have not yet been created during the lifetime of the strong electric field, which is of the order of, or less than, 1 fm/c.

Abstract: We present STAR measurements of the charge-dependent three-particle correlator gamma(a,b) = < cos(phi(a)(1) + phi(b)(2)-2 phi(3))>/v(2){2} and elliptic flow v(2){2} in U+U, Au+Au and p+Au collisions at RHIC. The difference Delta gamma = gamma(opposite sign)-gamma(same sign) measures charge separation across the reaction plane, a predicted signal of the Chiral Magnetic Effect (CME). Although charge separation has been observed, it has been argued that the measured separation can also be explained by elliptic flow related backgrounds. In order to separate the two effects we perform measurements of the gamma-correlator where background expectations differ from magnetic field driven effects. A differential measurement of gamma with the relative pseudorapidity (Delta eta)) between the first and second particles indicate that Delta gamma in peripheral A+A and p+A collisions are dominated by short-range correlations in A. However, a relatively wider component of the correlation in Delta eta tends to vanish the same way as projected magnetic field as predicted by MC-Glauber simulations.

Abstract: © 2016 The Author(s) Azimuthal correlations of charged hadrons with direct-photon (γdir) and neutral-pion (π0) trigger particles are analyzed in central Au+Au and minimum-bias p+p collisions at sNN=200 GeV in the STAR experiment. The charged-hadron per-trigger yields at mid-rapidity from central Au+Au collisions are compared with p+p collisions to quantify the suppression in Au+Au collisions. The suppression of the away-side associated-particle yields per γdirtrigger is independent of the transverse momentum of the trigger particle (pTtrig), whereas the suppression is smaller at low transverse momentum of the associated charged hadrons (pTassoc). Within uncertainty, similar levels of suppression are observed for γdirand π0triggers as a function of zT(≡pTassoc/pTtrig). The results are compared with energy-loss-inspired theoretical model predictions. Our studies support previous conclusions that the lost energy reappears predominantly at low transverse momentum, regardless of the trigger energy.

Abstract: We present measurements of the near side of triggered di-hadron correlations using neutral strange baryons ( A, (A) over bar) and mesons (K-s(0)) at intermediate transverse momentum ( 3 < p(T) < 6 GeV/c) to look for possible flavor and baryon-meson dependence. This study is performed in d+Au, Cu+Cu, and Au+Au collisions at root S-NN = 200 GeV measured by the STAR experiment at RHIC. The near-side di-hadron correlation contains two structures, a peak which is narrow in azimuth and pseudorapidity consistent with correlations from jet fragmentation, and a correlation in azimuth which is broad in pseudorapidity. The particle composition of the jet-like correlation is determined using identified associated particles. The dependence of the conditional yield of the jet-like correlation on the trigger particle momentum, associated particle momentum, and centrality for correlations with unidentified trigger particles are presented. The neutral strange particle composition in jet-like correlations with unidentified charged particle triggers is not well described by PYTHIA. However, the yield of unidentified particles in jet-like correlations with neutral strange particle triggers is described reasonably well by the same model.

Abstract: We present measurements of $\Omega$ and $\phi$ production at mid-rapidity from Au+Au collisions at nucleon-nucleon center-of-mass energies $\sqrt{s_{NN}}$ = 7.7, 11.5, 19.6, 27 and 39 GeV by the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). Motivated by the coalescence formation mechanism for these strange hadrons, we study the ratios of $N(\Omega^{-}+\Omega^{+})/(2N(\phi))$. These ratios as a function of transverse momentum ($p_T$) fall on a consistent trend at high collision energies, but start to show deviations in peripheral collisions at $\sqrt{s_{NN}}$ = 19.6, 27 and 39 GeV, and in central collisions at 11.5 GeV in the intermediate $p_T$ region of 2.4-3.6 GeV/c. We further evaluate empirically the strange quark $p_T$ distributions at hadronization by studying the $\Omega/\phi$ ratios scaled by the number of constituent quarks. The NCQ-scaled $\Omega/\phi$ ratios show a suppression of strange quark production in central collisions at 11.5 GeV compared to $\sqrt{s_{NN}} >= 19.6$ GeV. The shapes of the presumably thermal strange quark distributions in 0-60% most central collisions at 7.7 GeV show significant deviations from those in 0-10% most central collisions at higher energies. These features suggest that there is likely a change of the underlying strange quark dynamics in the transition from quark-matter to hadronic matter at collision energies below 19.6 GeV., Comment: 7 pages, 5 figures

Abstract: Azimuthal correlations of charged hadrons with direct-photon (gamma(dir)) and neutral-pion (pi(0)) trigger particles are analyzed in central Au+Au and minimum-bias p + p collisions at root S-NN = 200 GeV in the STAR experiment. The charged-hadron per-trigger yields at mid-rapidity from central Au+Au collisions are compared with p + p collisions to quantify the suppression in Au+Au collisions. The suppression of the away-side associated-particle yields per gamma(dir) trigger is independent of the transverse momentum of the trigger particle (p(T)(trig)), whereas the suppression is smaller at low transverse momentum of the associated charged hadrons (p(T)(assoc)). Within uncertainty, similar levels of suppression are observed for gamma(dir) and pi(0) triggers as a function of z(T) (equivalent to p(T)(assoc)/p(T)(tri)). The results are compared with energy-loss-inspired theoretical model predictions. Our studies support previous conclusions that the lost energy reappears predominantly at low transverse momentum, regardless of the trigger energy. (C) 2016 The Author(s). Published by Elsevier B.V.

Abstract: We present a measurement of the inclusive production of. mesons in U + U collisions at root s(NN) = 193 GeV at midrapidity (vertical bar y vertical bar < 1). Previous studies in central Au+Au collisions at root s(NN) = 200 GeV show a suppression of Upsilon (1S+2S+3S) production relative to expectations from the Upsilon yield in p+p collisions scaled by the number of binary nucleon-nucleon collisions (N-coll), with an indication that the.(1S) state is also suppressed. The present measurement extends the number of participant nucleons in the collision (N-part) by 20% compared to Au+Au collisions, and allows us to study a system with higher energy density. We observe a suppression in both the Upsilon (1S+2S+3S) and Upsilon (1S) yields in central U+U data, which consolidates and extends the previously observed suppression trend in Au+Au collisions.

Abstract: We report on the measurement of J/psi production in the dielectron channel at midrapidity (vertical bar y vertical bar < 1) in p + p and d + Au collisions at root s(NN) = 200 GeV from the STAR experiment at the Relativistic Heavy Ion Collider. The transverse momentum p(T) spectra in p + p for pT < 4 GeV/c and d + Au collisions for p(T) < 3 GeV/c are presented. These measurements extend the STAR coverage for J/psi production in p + p collisions to low p(T). The < p(T)(2)> from the measured J/psi invariant cross section in p + p and d + Au collisions are evaluated and compared to similar measurements at other collision energies. The nuclear modification factor for J/psi is extracted as a function of pT and collision centrality in d + Au and compared to model calculations using the modified nuclear parton distribution function and a final-state J/psi nuclear absorption cross section.

Abstract: We present measurements of second-order azimuthal anisotropy (v(2)) at midrapidity (vertical bar y vertical bar < 1.0) for light nuclei d, t, He-3 (for root s(NN) = 200, 62.4, 39, 27, 19.6, 11.5, and 7.7 GeV) and antinuclei (root s(NN) = 200, 62.4, 39, 27, and 19.6 GeV) and (3)(He) over bar (root s(NN) = 200 GeV) in the STAR (Solenoidal Tracker at RHIC) experiment. The v(2) for these light nuclei produced in heavy-ion collisions is compared with those for p and (p) over bar. We observe mass ordering in nuclei v(2)(p(T)) at low transverse momenta (p(T) < 2.0 GeV/c). We also find a centrality dependence of v(2) for d and . The magnitude of v(2) for t and He-3 agree within statistical errors. Light-nuclei v(2) are compared with predictions from a blast-wave model. Atomic mass number (A) scaling of light-nuclei v(2)(p(T)) seems to hold for p(T)/A < 1.5 GeV/c. Results on light-nuclei v(2) from a transport-plus-coalescence model are consistent with the experimental measurements.

44. Neutrophil-to-Lymphocyte Ratio Predicts Dialysis Timing & Prognosis in Critically Ill Patients.

Author: Nashwan AJ, Othman MI, Ananthegowda DC, Singh K, Ibraheem A, Janardhanan JP, Alikutty JP, Othman MA, Hamad AI, Khatib MY, and Abujaber AA
Abstract: Background and Aims: The neutrophil-to-lymphocyte ratio (NLR) is a cost-effective indicator of inflammation, which may impact decisions regarding therapy for patients undergoing continuous renal replacement therapy (CRRT), even with ongoing clinical arguments. This study aimed to examine the correlation between NLR and the prognosis of critically ill patients undergoing CRRT, specifically about mortality and morbidity. Additionally, the study sought to assess NLR's potential as a prognostic indicator for CRRT initiation., Methods: Data were retrospectively analyzed from 175 critically ill patients who received CRRT. Clinical factors and biochemical markers were compared between survivors and non-survivors at admission, before CRRT, and at 24 and 72 h post-CRRT initiation., Results: Elevated NLR levels were significantly associated with increased in-hospital mortality. Neutrophil counts showed statistical significance across all measurement points, while NLR and lymphocyte counts were significant only on the third day of CRRT ( p 0.001 and 0.011, respectively). Non-survivors had higher NLR values than survivors and experienced shorter hospital stays (median 22 vs. 44 days for survivors, p < 0.001). Patients with higher baseline NLR values also had more complications., Conclusions: The NLR shows potential as a prognostic predictor for mortality in CRRT patients. Its integration into clinical practice could enhance patient care and treatment timing, and further studies should validate its clinical utility., Competing Interests: Abdulqadir J. Nashwan is an editorial board member of Health Science Reports and coauthor of this article.

46. Pill-burden and its association with treatment burden among patients with advanced stages of chronic kidney disease.

Author: Al-Mansouri A, Hamad AI, Al-Ali FS, Ibrahim MIM, Kheir N, Al-Ziftawi NH, Ibrahim RA, AlBakri M, and Awaisu A
Abstract: Introduction: Chronic kidney disease (CKD) is associated with multimorbidity and high treatment burden. Pill-burden is one component of the overall treatment burden. However, little is known about its magnitude and contribution to the overall treatment burden among patients with advanced stages of CKD. This study aimed to quantify the magnitude of pill-burden in dialysis-dependent vs. non-dialysis-dependent advanced-stage CKD patients and its association with treatment burden., Methods: This was a cross-sectional study for the assessment of pill-burden and treatment burden among non-dialysis and hemodialysis (HD)-dependent CKD patients. Pill-burden was quantified as "number of pills/patient/week" through electronic medical record, while treatment burden was assessed using the "Treatment Burden Questionnaire (TBQ)". Furthermore, oral and parenteral medication burden was also quantified. Data were analyzed using both descriptive and inferential analysis, including Mann - Whitney U test and two-way between groups analysis of variance (ANOVA)., Results: Among the 280 patients included in the analysis, the median (IQR) number of prescribed chronic medications was 12 (5.7) oral and 3 (2) parenteral medications. The median (IQR) pill-burden was 112 (55) pills/week. HD patients experienced higher pill-burden than non-dialysis patients [122 (61) vs. 109 (33) pills/week]; however, this difference did not reach statistical significance (p = 0.81). The most commonly prescribed oral medications were vitamin D (90.4%), sevelamer carbonate (65%), cinacalcet (67.5%), and statins (67.1%). Overall, patients who had high pill-burden (≥112 pills/week) had significantly higher perceived treatment burden compared to low pill-burden patients (<112 pills/week) [47(36.2) vs. 38.5(36.7); p = 0.0085]. However, two-way ANOVA showed that dialysis status is the significant contributor to the treatment-burden in the high overall pill-burden group (p < 0.01), the high oral-medication-burden group (p < 0.01), and the high parenteral-medication-burden group (p = 0.004)., Conclusions: Patients with advanced CKD experienced a high pill-burden, which increases the treatment burden; however, the dialysis status of the patient is the main factor affecting the overall treatment burden. Future intervention studies should target this population with an aim to reduce polypharmacy, pill-burden, and treatment burden, which may ultimately improve CKD patients' quality of life., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

Abstract: Elliptic flow measurements from two-, four-, and six-particle correlations are used to investigate flow fluctuations in collisions of U+U at sqrt[s_{NN}]=193 GeV, Cu+Au at sqrt[s_{NN}]=200 GeV and Au+Au spanning the range sqrt[s_{NN}]=11.5-200 GeV. The measurements show a strong dependence of the flow fluctuations on collision centrality, a modest dependence on system size, and very little if any, dependence on particle species and beam energy. The results, when compared to similar LHC measurements, viscous hydrodynamic calculations, and trento model eccentricities, indicate that initial-state-driven fluctuations predominate the flow fluctuations generated in the collisions studied.

48. Atherogenic Index of Plasma and Anthropometric Measurements among Osteoporotic Postmenopausal Sudanese Women: Possible Risk for Cardiovascular Disease.

Author: Elmugadam A, Elfadil GA, Hamad AI, El Shikieri AB, Aledrissy M, and Altayb HN
Abstract: Introduction: Data examining the health of menopausal women and the prevalence of osteoporosis remain to be limited in Africa, especially in sub-Saharan countries. Thus, in this current study, we aimed to assess the atherogenic index of plasma (AIP) and anthropometric measurements of osteoporotic postmenopausal women and determine their risk for cardiovascular disease (CVD)., Methods: This is a cross-sectional, community-based study. Postmenopausal women ( n = 300), aged ≥45 years, were recruited from Khartoum state, Sudan. Dual-energy X-ray absorptiometry was used to assess bone density. Weight, height, and waist circumference were measured twice. Fasting blood samples (5 ml) were collected to determine total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). AIP was calculated as an indicator of CVD risk., Results: The mean age of the postmenopausal women was 61.6 ± 10.2 years (range 47-90 years). Women ( n = 80) had the normal T -score, and an equal number had osteoporosis ( n = 110) and osteopenia ( n = 110). The prevalence of osteoporosis was 36.7%. Many postmenopausal women with normal T -scores suffered from general (71.2%) and central (94%) obesity. Postmenopausal women had high TC (24.4%), TG (25.6%), LDL-C (13.7%), and low HDL-C (76.0%) levels. Osteoporotic women (36.4%) were found to have a medium to high risk of CVD as determined by AIP. Women with normal T -scores had a higher number of CVD risk factors. A positive correlation was noted between AIP and TC among osteopenic ( r = 0.292; P =0.002) and osteoporotic women ( r = 0.265; P < 0.001)., Conclusion: Osteoporosis was prevalent among Sudanese postmenopausal women who also had an increased risk for CVD. Public health education about osteoporosis and CVD risk is thus recommended., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Abdelgadir Elmugadam et al.)

Abstract: The STAR Collaboration reports measurements of back-to-back azimuthal correlations of di-π^{0}s produced at forward pseudorapidities (2.6<η<4.0) in p+p, p+Al, and p+Au collisions at a center-of-mass energy of 200 GeV. We observe a clear suppression of the correlated yields of back-to-back π^{0} pairs in p+Al and p+Au collisions compared to the p+p data. The observed suppression of back-to-back pairs as a function of transverse momentum suggests nonlinear gluon dynamics arising at high parton densities. The larger suppression found in p+Au relative to p+Al collisions exhibits a dependence of the saturation scale Q_{s}^{2} on the mass number A. A linear scaling of the suppression with A^{1/3} is observed with a slope of -0.09±0.01.

50. National response to the COVID-19 Omicron variant crisis in the ambulatory hemodialysis service in the State of Qatar.

Author: Hamad AI, Asim M, Othman MA, Abuhelaiqa EA, Shurrab A, Elmadhoun IT, Ali Al-Malki H, and Alkadi MM
Abstract: The coronavirus disease (COVID-19) pandemic has had a significant worldwide impact since its emergence in 2019. End-stage kidney disease patients have been among the most vulnerable population affected and have a higher risk of acquiring infection and developing more severe disease. We have encountered three major COVID-19 waves in Qatar and they have required different strategies to overcome. The most recent wave was due to the Omicron variant characterized by higher transmissibility. The monthly incidence of COVID-19 infection during the Omicron wave in patients with end-stage renal disease peaked at 256 patients compared to 35 and 39 patients during the first and second waves, respectively. In addition, more than one-third of our dialysis staff became infected during this wave. Unlike the previous two waves, COVID-19 due to the Omicron variant was less severe with only 5% of hemodialysis patients requiring admission to the intensive care unit compared to 25% during the previous waves. The Omicron variant wave resulted in a crisis in our country due to the high number of non-hospitalized COVID-19 hemodialysis patients and the severe staff shortage. Several measures were taken to overcome the crisis, such as designating one facility to dialyze all COVID-19 ambulatory patients, reducing dialysis sessions to 3 hours, and introducing a fourth dialysis shift. This article describes the challenges we faced in the ambulatory hemodialysis service during the Omicron wave and the measures taken in the COVID-19 and non-COVID-19 designated facilities to combat the crisis., (© 2022 Hamad, Asim, Othman, Abuhelaiqa, Shurrab, Elmadhoun, Al-Malki, Alkadi, licensee HBKU Press.)
