Descriptive study of functional outcome and complication of fracture calcaneum treated with locking calcaneum plate

Background: Fracture of calcaneum accounts for about 2% of all fractures and 75% of all calcaneum fractures are intra-articular. Numerous controversies existed regarding optimal treatment of displaced intraarticular calcaneum fractures. In this study evaluate post-operative functional outcome and complication of fracture calcaneum treated with locking calcaneum plate.Methods: This hospital based prospective descriptive study was conducted on 108 patients (120 calcaneum fracture) operated between July 2016 to December 2018 by open reduction and internal fixation with locking calcaneum plate through extensive lateral approach at Department of Orthopaedics, SMS Medical college and hospital, Jaipur. All close displaced intraarticular calcaneal fracture was included in the study.Results: Average duration between injury and surgery was 8.3±2.97 days. Out of 120 calcaneum fracture 52 fractures (43.33%) were Sander’s type II, 52 fractures (43.33%) were Sander’s type III, and 16 fractures (13.33%) were Sander’s type IV. Pain on weight bearing was noted in 20 patients (16.66%) implant prominence was noted in 8 patients and delayed wound healing was seen in 4 patients. Maryland foot score was excellent in 44 fracture (36.67%), good in 56 fractures (46.67%), fair in 8 fractures (6.67%), and poor in 12 fractures (10%).Conclusions: Open reduction and internal fixation (ORIF) with locking calcaneum plate in an indicated case, with respect to soft tissue envelope and early rehabilitation, leads to better therapeutic results as compared to other operative technique

Measurement of deuteron spectra and elliptic flow in Pb-Pb collisions at root s(NN)=2.76 TeV at the LHC

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPThe transverse momentum (p(T)) spectra and elliptic flow coefficient (v(2)) of deuterons and anti-deuterons at mid-rapidity (|y| < 0.5) are measured with the ALICE detector at the LHC in Pb-Pb collisions at root s(NN) = 2.76 TeV. The measurement of the p(T) spectra of (anti-)deuterons is done up to 8 GeV/c in 0-10% centrality class and up to 6 GeV/c in 10-20% and 20-40% centrality classes. The v(2) is measured in the 0.8 < p(T) < 5 GeV/c interval and in six different centrality intervals (0-5, 5-10, 10-20, 20-30, 30-40 and 40-50%) using the scalar product technique. Measured pi(+/-), K-+/- and p+(p) over bar transverse-momentum spectra and v(2) are used to predict the deuteron p(T) spectra and v(2) within the Blast-Wave model. The predictions are able to reproduce the v(2) coefficient in the measured p(T) range and the transverse-momentum spectra for p(T) gt; 1.8 GeV/c within the experimental uncertainties. The measurement of the coalescence parameter B-2 is performed, showing a p(T) dependence in contrast with the simplest coalescence model, which fails to reproduce also the measured v(2) coefficient. In addition, the coalescence parameter B-2 and the elliptic flow coefficient in the 20-40% centrality interval are compared with the AMPT model which is able, in its version without string melting, to reproduce the measured v(2)(p(T)) and the B-2(p(T)) trend.7710120CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFINANCIADORA DE ESTUDOS E PROJETOS - FINEPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPSem informaçãoSem informaçãoSem informaçãoThe ALICE Collaboration would like to thank all its engineers and technicians for their invaluable contributions to the construction of the experiment and the CERN accelerator teams for the outstanding performance of the LHC complex.

Constraining the magnitude of the chiral magnetic effect with event shape engineering in Pb-Pb collisions at root s(NN)=2.76 TeV

CNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOFINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOIn ultrarelativistic heavy-ion collisions, the event-by-event variation of the elliptic flow v(2) reflects fluctuations in the shape of the initial state of the system. This allows to select events with the same centrality but different initial geometry. This selection technique, Event Shape Engineering, has been used in the analysis of charge-dependent two-and three-particle correlations in Pb-Pb collisions at root s(NN) = 2.76 TeV. The two-particle correlator < cos(phi(alpha) - phi(ss))gt;, calculated for different combinations of charges alpha and beta, is almost independent of v(2) (for a given centrality), while the three-particle correlator < cos(phi(alpha) + phi(beta) - 2 Psi(2))gt; scales almost linearly both with the event v(2) and charged-particle pseudorapidity density. The charge dependence of the three-particle correlator is often interpreted as evidence for the Chiral Magnetic Effect (CME), a parity violating effect of the strong interaction. However, its measured dependence on v(2) points to a large non-CME contribution to the correlator. Comparing the results with Monte Carlo calculations including a magnetic field due to the spectators, the upper limit of the CME signal contribution to the three-particle correlator in the 10-50% centrality interval is found to be 26-33% at 95% confidence level.777151162CNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOFINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOCNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOFINEP - FINANCIADORA DE ESTUDOS E PROJETOSFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOSem informaçãoSem informaçãoSem informaçãoAgências de fomento estrangeiras apoiaram essa pesquisa, mais informações acesse artig

Longitudinal asymmetry and its effect on pseudorapidity distributions in Pb-Pb collisions at root s(NN)=2.76 TeV

First results on the longitudinal asymmetry and its effect on the pseudorapidity distributions in Pb-Pb collisions at root s(NN) = 2.76 TeV at the Large Hadron Collider are obtained with the ALICE detector. The longitudinal asymmetry arises because of an unequal number of participating nucleons from the two colliding nuclei, and is estimated for each event by measuring the energy in the forward neutron-Zero-Degree-Calorimeters (ZNs). The effect of the longitudinal asymmetry is measured on the pseudorapidity distributions of charged particles in the regions vertical bar eta vertical bar < 0.9, 2.8 < eta < 5.1 and -3.7 < eta < -1.7 by taking the ratio of the pseudorapidity distributions from events corresponding to different regions of asymmetry. The coefficients of a polynomial fit to the ratio characterise the effect of the asymmetry. A Monte Carlo simulation using a Glauber model for the colliding nuclei is tuned to reproduce the spectrum in the ZNs and provides a relation between the measurable longitudinal asymmetry and the shift in the rapidity (y(0)) of the participant zone formed by the unequal number of participating nucleons. The dependence of the coefficient of the linear term in the polynomial expansion, c(1), on the mean value of y(0) is investigated.Peer reviewe

Global management of a common, underrated surgical task during the COVID-19 pandemic: Gallstone disease - An international survery

Background: Since the Coronavirus disease-19(COVID-19) pandemic, the healthcare systems are reallocating their medical resources, with consequent narrowed access to elective surgery for benign conditions such as gallstone disease(GD). This survey represents an overview of the current policies regarding the surgical management of patients with GD during the COVID-19 pandemic. Methods: A Web-based survey was conducted among 36 Hepato-Prancreato-Biliary surgeons from 14 Countries. Through a 17-item questionnaire, participants were asked about the local management of patients with GD since the start of the COVID-19 pandemic. Results: The majority (n = 26,72.2%) of surgeons reported an alarming decrease in the cholecystectomy rate for GD since the start of the pandemic, regardless of the Country: 19(52.7%) didn't operate any GD, 7(19.4%) reduced their surgical activity by 50–75%, 10(27.8%) by 25–50%, 1(2.8%) maintained regular activity. Currently, only patients with GD complications are operated. Thirty-two (88.9%) participants expect these changes to last for at least 3 months. In 15(41.6%) Centers, patients are currently being screened for SARS-CoV-2 infection before cholecystectomy [in 10(27.8%) Centers only in the presence of suspected infection, in 5(13.9%) routinely]. The majority of surgeons (n = 29,80.6%) have adopted a laparoscopic approach as standard surgery, 5(13.9%) perform open cholecystectomy in patients with known/suspected SARS-CoV-2 infection, and 2(5.6%) in all patients. Conclusion
