Joint Awareness After Fixed and Mobile-Bearing Total Knee Arthroplasty With Minimum 12 Years of Follow-Up: a Propensity Matched-Pair Analysis
No full textBackground: Many comparative articles studied mobile-bearing (MB) and fixed-bearing (FB) total knee arthroplasties (TKAs). Meta-analyses found no difference in survival or biomechanical outcome. This study aimed to compare long-term clinical results between fixed-bearing (FB) and mobile-bearing (MB) total knee arthroplasty (TKA) as well as patients' adaptation to their artificial joints.Method: TKAs performed with the same surgical protocol divided into categories according to the insert design preferred. 70 MB design TKAs were compared with 70 FB design TKAs utilizing propensity matching for parameters; gender, age, body mass index, coronal plane deformity, range of motion (ROM) and appropriateness criteria. Forgotten Joint Score-12 (FJS-12) was used to assess patients' ability to forget their artificial joints in daily life.Results: Patients had a mean follow-up of 15.6 (+/- 2.2) years. No difference was observed between groups for post-operative ROM, WOMAC, Knee Society Knee and Function Scores. The FJS-12 in the MB and FB groups were 66.1 and 72.8, respectively (P = 0.026). There was no significant difference in survival between both designs.Conclusion: This study suggests that in TKA, joint awareness is higher in MB compared to FB design. FJS-12 appears to be a sensitive measuring tool when comparing two designs and should be implemented in long-term follow-up.(c) 2023 Elsevier B.V. All rights reserved
Management and Outcomes of Major Pelvic Hemorrhage in Complex Abdomino-Pelvic Surgery
No full textIntroduction: Hemorrhage is a challenging complication of pelvic surgery. This study aimed to analyze the causes, management and factors associated with morbidity in patients experiencing major pelvic hemorrhage during complex abdomino-pelvic surgery.Methods: Patients who had major intraoperative pelvic hemorrhage during complex abdomino-pelvic surgery at 11 tertiary referral centers between 1997-2017 were included. Patient characteristics, management strategies to control bleeding, short and long term postoperative outcomes were evaluated retrospectively.Results: There were 120 patients with a mean age of 56.6 +/- 2.4 years and a mean BMI of 28.3 +/- 1 kg/m(2). While 104 (95%) of the patients were operated for malignancy, 16(5%) of the patients had surgery for a benign disease. The most common bleeding site was the presacral venous plexus 90(75%). Major pelvic hemorrhage was managed simultaneously in 114(95 %) patients. Electrocauterization 27(23%), pelvic packing 26(22%), suturing 7(6%), thumbtacks application 7(6%), muscle welding 4(4%), use of energy devices 2(2%) and topical hemostatic agents 2(2%) were the management tools. Combined techniques were used in 43(36%) patients. Short-term morbidity and mortality rates were 48(40%) and 2(2%), respectively. High preoperative CRP levels(p=0.04), history of preoperative radiotherapy (p=0.04), longer bleeding time (p=0.006) and increased blood transfusion (p=0.005) were the factors associated with postoperative morbidity.Discussion/Conclusion: Postoperative morbidity related to major pelvic hemorrhage can be reduced by optimizing the risk factors. Prehabilitation prior to surgery to moderate inflammatory status and prompt action with proper technique to control major pelvic hemorrhage can prevent excessive blood loss in complex abdomino-pelvic surgery
Search for Dark Matter Produced in Association With a Single Top Quark and an Energetic W Boson in √s=13 Tev Pp Collisions With the Atlas Detector
No full textThis paper presents a search for dark matter, chi, using events with a single top quark and an energetic W boson. The analysis is based on proton-proton collision data collected with the ATLAS experiment at root s = 13 TeV during LHC Run 2 (2015-2018), corresponding to an integrated luminosity of 139 fb(-1). The search considers final states with zero or one charged lepton (electron or muon), at least one b-jet and large missing transverse momentum. In addition, a result from a previous search considering two-charged-lepton final states is included in the interpretation of the results. The data are found to be in good agreement with the Standard Model predictions and the results are interpreted in terms of 95% confidence-level exclusion limits in the context of a class of dark matter models involving an extended two-Higgs-doublet sector together with a pseudoscalar mediator particle. The search is particularly sensitive to on-shell production of the charged Higgs boson state, H-+/-, arising from the two-Higgs-doublet mixing, and its semi-invisible decays via the mediator particle, a: H-+/- -> W(+/-)a(-> chi chi). Signal models with H-+/- masses up to 1.5 TeV and a masses up to 350 GeV are excluded assuming a tan beta value of 1. For masses of a of 150 (250) GeV, tan beta values up to 2 are excluded for H-+/- masses between 200 (400) GeV and 1.5 TeV. Signals with tan beta values between 20 and 30 are excluded for H-+/- masses between 500 and 800 GeV.ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW, Austria; FWF, Austria; ANAS, Azerbaijan; CNPq, Brazil; FAPESP, Brazil; NSERC, Canada; CFI, Canada; NSFC, China; MEYS CR, Czech Republic; DNRF, Denmark; DNSRC, Denmark; IN2P3-CNRS, France; CEA-DRF/IRFU, France; BMBF, Germany; MPG, Germany; Hong Kong SAR, China; ISF, Israel; INFN, Italy; MEXT, Japan; JSPS, Japan; CNRST, Morocco; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; MESTD, Serbia; MSSR, Slovakia; ARRS, Slovenia; MIZS, Slovenia; MICINN, Spain; Wallenberg Foundation, Sweden; SERI, Switzerland; MOST, Taiwan; DOE, United States of America; NSF, United States of America; BCKDF, Canada; CANARIE, Canada; Compute Canada, Canada; Czech Republic [PRIMUS 21/SCI/017, UNCE SCI/013]; COST, European Union; ERC, European Union; ERDF, European Union; Horizon 2020, European Union; Marie Skodowska-Curie Actions, European Union; Investissements d'Avenir Labex, France; Investissements d'Avenir Idex , France; ANR, France; DFG , Germany; AvH Foundation, Germany; Herakleitos programme - EU-ESF, Greece; Thales programme - EU-ESF, Greece; Aristeia programme - EU-ESF, Greece; Greek NSRF, Greece; BSF-NSF, Israel; MINERVA, Israel; Norwegian Financial Mechanism 2014-2021, Norway; NCN, Poland; NAWA, Poland; La Caixa Banking Foundation, Spain; CERCA Programme Generalitat de Catalunya, Spain; PROMETEO Programme Generalitat Valenciana, Spain; GenT Programme Generalitat Valenciana, Spain; Goran Gustafssons Stiftelse, Sweden; Royal Society, United Kingdom; Leverhulme Trust, United Kingdom; STFC, United Kingdom; TENMAK, Turkiye; Canton of Geneva, Switzerland; Canton of Bern, Switzerland; SNSF, Switzerland; SRC, Sweden; DSI/NRF, South Africa; NWO, Netherlands; Benoziyo Center, Israel; RGC, China; GSRI, Greece; HGF, Germany; SRNSFG, Georgia; Minciencias, Colombia; MOST, China; CAS, ChinaWe thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.

Measurements of Zγ Plus Jets Differential Cross Sections in Pp Collisions at √s=13 Tev With the Atlas Detector
No full textDifferential cross-section measurements of Z gamma production in association with hadronic jets are presented, using the full 139 fb(-1) dataset of root s = 13 TeV proton-proton collisions collected by the ATLAS detector during Run 2 of the LHC. Distributions are measured using events in which the Z boson decays leptonically and the photon is usually radiated from an initial-state quark. Measurements are made in both one and two observables, including those sensitive to the hard scattering in the event and others which probe additional soft and collinear radiation. Different Standard Model predictions, from both parton-shower Monte Carlo simulation and fixed-order QCD calculations, are compared with the measurements. In general, good agreement is observed between data and predictions from MATRIX and MiNNLOPS, as well as next-to-leading-order predictions from MadGraph5_aMC@NLO and Sherpa.ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW; FWF, Austria; ANAS; CNPq; FAPESP, Brazil; NSERC; CFI, Canada; NSFC, China; MEYS CR, Czech Republic; DNRF; DNSRC, Denmark; IN2P3-CNRS; CEA-DRF/IRFU, France; BMBF; MPG, Germany; RGC and Hong Kong SAR, China; ISF and Benoziyo Center, Israel; INFN, Italy; MEXT; JSPS, Japan; CNRST, Morocco; NWO, Netherlands; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; MESTD, Serbia; MSSR, Slovakia; ARRS; MIZS, Slovenia; MICINN, Spain; Wallenberg Foundation, Sweden; SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; DOE; NSF, United States of America; BCKDF; CANARIE; CRC, Canada [PRIMUS 21/SCI/017, UNCE SCI/013]; Czech Republic; ERC; ERDF; Marie Sklodowska-Curie Actions, European Union; Investissements d'Avenir Labex, Investissements d'Avenir Idex; ANR, France; DFG; AvH Foundation, Germany - EU-ESF; Greek NSRF, Greece; BSF-NSF; NCN; La Caixa Banking Foundation; CERCA Programme Generalitat de Catalunya; PROMETEO; Generalitat Valenciana, Spain; Goran Gustafssons Stiftelse, Sweden; Royal Society; Leverhulme Trust, United KingdomWe acknowledge the support of ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW and FWF, Austria; ANAS, Azerbaijan; CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada; CERN; ANID, Chile; CAS, MOST and NSFC, China; Minciencias, Colombia; MEYS CR, Czech Republic; DNRF and DNSRC, Denmark; IN2P3-CNRS and CEA-DRF/IRFU, France; SRNSFG, Georgia; BMBF, HGF and MPG, Germany; GSRI, Greece; RGC and Hong Kong SAR, China; ISF and Benoziyo Center, Israel; INFN, Italy; MEXT and JSPS, Japan; CNRST, Morocco; NWO, Netherlands; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; MESTD, Serbia; MSSR, Slovakia; ARRS and MIZS, Slovenia; DSI/NRF, South Africa; MICINN, Spain; SRC and Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; TENMAK, Turkiye; STFC, United Kingdom; DOE and NSF, United States of America.

Recent Advances in Porous Nanomaterials-Based Drug Delivery Systems for Osteoarthritis
No full textOsteoarthritis (OA) is a common degenerative disease that develops over time, characterized mainly by inflammatory joints, cartilage deterioration, and ultimately loss of normal joint function. Some of the limitations that restrict the effectiveness of current OA treatment procedures include minimal penetration of medications into cartilage and lack of vascularity, leading to insufficient bioavailability and systemic toxicity. To increase the effectiveness of treatment, it is necessary to create novel non-invasive OA treatment techniques. Porous nanomaterials (PNMs) show great promise as sustained drug delivery systems (DDSs) due to their functionality, variable porosity, and high loading capacity. In addition, they can provide targeted drug delivery, facilitate controlled release of drugs, and prolong drug circulation and retention time while reducing adverse reactions and improving drug solubility. First, the current treatment methods and challenges are summarized. Subsequently, recent advances in DDSs for OA treatment based on PNMs with various pore sizes and structures are presented. Lastly, the parameters that affect the performance of DDSs are discussed by giving some suggestions for their design. The purpose of this review is to provide new insights into PNM-based DDS design and to inspire readers to adopt the smart design of intra-articular DDSs in the future
Ganoderma Lucidum (reishi Mantarı) Kullanımına Bağlı Uygunsuz Duygulanım
No full textGİRİŞ ve AMAÇ: Ganoderma lucidum (Reishi mantarı), ganoderma cinsine bağlı Avrupa ve Çin’in bazı bölgelerinde yetişen bir mantar türüdür. Ganoderma lucidum’un polisakkarit bileşenlerinin antitümör etkileri araştırılmaktadır, ancak henüz yeterli kanıtlara ulaşılmamıştır. Bu yazıda, remisyonda meme kanseri öyküsü olan, Reishi mantarı kullanan ve ruhsal sorunlarla psikiyatriye başvuran bir olguyu tartışmak amaçlanmıştır. OLGU: Üç buçuk yıl önce meme kanseri tanısı konan ve operasyon sonrası kemoterapi alan kırk altı yaşında kadın hasta sinirlilik yakınmasıyla psikiyatri polikliniğine başvurdu. Hastanın yapılan muayenesinde duygulanımının uygunsuz olduğu, üzüntü verici olayları anlatırken gülmesini tutmakta zorlandığı, belirgin psikotik bulgu saptanmasa da güvensiz bir tutum içinde olduğu gözlendi. Hastanın yakınmaları sorgulandığında çabuk sinirlendiğini, gündelik olumsuz yaşam olaylarının ruh halini çabuk etkilediğini, eşinin isteğiyle psikiyatriye başvurduğunu belirtti. Hastanın öyküsünde hipomani/maniyi düşündürecek uykusuzluk, hareketlerde ve konuşmada hızlanma, büyüklük düşünceleri, zevk veren uğraşılara aşırı ilgi gibi belirtiler mevcut değildi. Hastanın geçmişte üç ay essitalopram 10 mg/gün kullanımı olduğu, o dönemde daha sakin olduğu, hipomanik/manik belirti olmadığı öğrenildi. Kanser tanısı aldıktan sonra, doktorunun kullanmasını önermemesine rağmen, her gün Reishi mantarı tükettiğini, başka bir tedavi almadığını belirtti. Yakınından alınan bilgiye göre, duygulanımındaki uygunsuzluk ve oynaklığın yaklaşık iki yıldır olduğu, çabuk sinirlendiği, kişilerarası ilişkilerde çatışmalar yaşadığı, mantar dozunu giderek arttırdığı, hastanın bir ay içinde yapılan kontrolünde meme kanserinin remisyonda olduğu öğrenildi. Hastayla yapılan görüşmede mantar kullanımını kesmesi istendi, olanzapin 5 mg/ gün reçete edildi, belirtilerde ilk günlerden itibaren yatışma gözlendi. Olgudan onam alındı. TARTIŞMA ve SONUÇ: Reishi mantarı yeterli kanıt olmasa da kanser hastaları tarafından kullanılabilmektedir, ancak nöropsikiyatrik etkileriyle ilgili çalışmalar kısıtlıdır, dopaminerjik nöron ve mikroglia ortak kültürlerinde nöroprotektif etkisinin gösterilmesi Parkinson hastaları için umut verici bir ajan olarak nitelendirilmiştir. Ganoderma lucidum’un, bağışıklığı artırdığı, antitümör, antimikrobiyal, antiinflamatuar, analjezik ve antioksidan etkileri olduğu, antidepresan benzeri bir etki gösterdiği ve anksiyeteyi azalttığı öne sürülmektedir. Ancak Türkiye’den bir olgu bildirimi dışında duygulanım üzerine etkisi ile ilgili yeterli veri bulunmamaktadır, yazının bu anlamda katkı sağlayacağı düşünülmüştür
Measurement of the Production of a W Boson in Association With a Charmed Hadron in Pp Collisions at P S=13 Tev With the Atlas Detector
No full textThe production of a W boson in association with a single charm quark is studied using 140 fb(-1) of vS = 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. ffiffis The charm quark is tagged by the presence of a charmed hadron reconstructed with a secondary-vertex fit. The W boson is reconstructed from the decay to either an electron or a muon and the missing transverse momentum present in the event. The charmed mesons reconstructed are D+ ?K-p+p+ and D*+ ? D0p+ ? (K-p+)p+ and the charge conjugate decays in the fiducial regions where pT(e; mu) > 30 GeV, l?(e; mu)l 2.5, pT(D(*)) > 8 GeV, and l?(D(*))l 2.2. The integrated and normalized differential cross sections as a function of the pseudorapidity of the lepton from the W boson decay, and of the transverse momentum of the charmed hadron, are extracted from the data using a profile likelihood fit. The measured total fiducial cross sections are sfidOS-SS(W- + D+) = 50.2 + 0.2(stat)+2.4 -2.3(syst) pb, s(OS-SS) (fid)(W- + D+) = 48.5 + 0.2(stat)+2.3-2.2(syst) pb, sfidOS-SS(W- + D*+) = 51.1 + 0.4(stat)+1.9 -1.8 (syst) pb, and s(OS-SS) (fid)(W+ + D*-) = 50.0 + 0.4(stat)+1.9 -1.8 (syst) pb. Results are compared with the predictions of next-to-leading-order quantum chromodynamics calculations performed using state-of-the-art parton distribution functions. Additionally, the ratio of charm to anticharm production cross sections is studied to probe the s -s- quark asymmetry. The ratio is found to be R+ c = 0.971 + 0.006(stat) + 0.011(syst). The ratio and cross-section measurements are consistent with the predictions obtained with parton distribution function sets that have a symmetric s -s- sea, indicating that any s -s- asymmetry in the Bjorken-x region relevant for this measurement is small.ANPCyT, Argentina; YerevaYerevan Physics Institute (YerPhI), Armenian Physics Institute (YerPhI), Armenia; ARC, Australia; BMWFW, Austria; FWF, Austria; ANAS, Azerbaijan; CNPq, Brazil; FAPESP, Brazil; NSERC, Canada; NRC, Canada; CFI, Canada; CERN; ANID, Chile; CAS, China; MOST, China; NSFC, China; Minciencias, Colombia; MEYS CR, Czech Republic; DNRF, Denmark; Danish Natural Science Research Council (DNSRC), Denmark; IN2P3-CNRS, France; Institut de recherche sur les lois fondamentales de l'Univers, Direction des Sciences de la Matiere, Commissariat a l'Energie Atomique (CEA-DRF/IRFU), France; Shota Rustaveli National Science Foundation of Georgia (SRNSFG), Georgia; BMBF, Germany; HGF, Germany; MPG, Germany; General Secretariat for Research and Innovation (GSRI), Greece; RGC, China; Hong Kong SAR, China; ISF, Israel; Benoziyo Center, Israel; INFN, Italy; MEXT, Japan; JSPS, Japan; CNRST, Morocco; NWO, Netherlands; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; MESTD, Serbia; Ministry of Education, Science, Research and Sport (MSSR), Slovakia; ARRS, Slovenia; DSI/NRF, South Africa; MICINN, Spain; Swedish Research Council (SRC); Wallenberg Foundation, Sweden; SERI; SNSF; Cantons of Bern; Geneva, Switzerland; MIZZ, Slovenia; MOST, Taiwan; TENMAK, Tuerkiye; STFC, United Kingdom; DOE; NSF, USA; BCKDF; CANARIE; Compute Canada; CRC, Canada; RIMUS Research Programme; University Research Center, Czech Republic; COST; ERC; ERDF; Horizon 2020; Marie Sklodowska-Curie Actions, European Union; Investissements d'Avenir Labex; Investissements d'Avenir Idex; ANR, France; DFG; AvH Foundation, Germany; Herakleitos, Thales; EU-ESF; National Strategic Reference Framework (Greek NSRF), Greece; BSF-NSF; MINERVA Foundation (MINERVA), Israel; Norwegian Financial Mechanism 2014-2021, Norway [PRIMUS 21/SCI/017]; NCN; NAWA, Poland; La Caixa Banking Foundation; CERCA Programme Generalitat de Catalunya; PROMETEO; GenT Programmes Generalitat Valenciana (PROMETEO); GenT Programmes Generalitat Valenciana, Spain; Goeran Gustafssons Stiftelse, Sweden; Royal Society and Leverhulme Trust, United Kingdom; [UNCE SCI/013]We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.

Measurement of the Inclusive T(t)over-Bar Production Cross Section in the Lepton Plus Jets Channel in Pp Collisions at √s=7 Tev With the Atlas Detector Using Support Vector Machines
No full textA measurement of the top quark pair-production cross section in the lepton + jets decay channel is presented. It is based on 4.6 fb(-1) of root s = 7 TeV pp collision data collected during 2011 by the ATLAS experiment at the CERN Large Hadron Collider. A three-class, multidimensional event classifier based on support vector machines is used to differentiate t (T) over bar events from backgrounds. The tt production cross section is found to be sigma(t (t) over bar) = 168.5 +/- 0.7(stat)(-5.9)(+6.2) (syst)(-3.2)(+3.4) (lumi) pb. The result is consistent with the Standard Model prediction based on QCD calculations at next-to-next-to-leading order.CNRST, Morocco; NWO, Netherlands; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; MESTD, Serbia; MSSR, Slovakia; ARRS; MICINN, Spain; SRC; Wallenberg Foundation, Sweden; SNSF and Cantons of Bern and Geneva, Switzerland; MOST, Taiwan; STFC, United Kingdom; DOE; NSF, United States of America; BCKDF; CANARIE; CRC, Canada [UNCE SCI/013]; Czech Republic; ERC; ERDF; European Union; Investissements d'Avenir Labex, Investissements d'Avenir Idex; ANR, France; DFG; AvH Foundation, Germany - EU-ESF; Greek NSRF, Greece; BSF-NSF; NCN; La Caixa Banking Foundation; CERCA Programme Generalitat de Catalunya; PROMETEO; Generalitat Valenciana, Spain; Gran Gustafssons Stiftelse, Sweden; Royal Society; Leverhulme Trust, United Kingdom; NDGF (Denmark, Norway, Sweden); KIT/GridKA (Germany); INFN-CNAF (Italy); NL-T1 (Netherlands) , PIC (Spain); ASGC (Taiwan); BNL (USA)We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.
