Relaps refrakter multiple myelomda daratumumabın tekli ve kombine tedavi sonuçları-tek merkez deneyimi
Authors: AKDENİZ Aydan , AKBAŞ Fatma , TOMBAK Anıl 
Published: December 2021

Giriş ve Amaç: Son yıllarda multipl miyelom tedavi protokollerine proteazom inhibitörleri ve immünomodülatörlerin eklenmesiyle, yanıt oranları önemli ölçüde iyileşmiştir, ancak relaps refrakter hastalarda tedavi seçenekleri hala sınırlıdır ve sağkalım kısadır. Daratumumab, bir insan CD38 monoklonal antikorudur ve hem monoterapi ile hem de kombinasyon terapilerinde çok iyi bir yanıt elde etmiştir.
Klinik çalışmalarda etkinliği kanıtlanmış olmasına rağmen, daratumumabın gerçek yaşam verilerinden elde edilen literatür bilgileri ülkemizde oldukça sınırlıdır. Bu nedenle merkezimizde daratumumab ile tedavi edilen hastaların karakteristik özelliklerini ve yanıt oranlarını incelemeyi amaçladık.
Gereç ve Yöntemler: : Daratumumab ile tedavi edilen 10 hastanın dosyaları geriye dönük olarak incelendi. Demografik bilgileri ve yanıt oranlarını içeren veriler literatür ışığında geliştirildi.
Bulgular: Hastaların ortalama tanı yaşı 58 idi. Medyan takip süresi 58,3 ay ve medyan daratumumab tedavi süresi 3,9 aydı. Medyan genel yanıt oranı % 40 idi. En az kısmi yanıt alınan tüm hastalar dara-bor-dex kombinasyonu alıyordu. Hastaların toplam % 60'ı hayattaydı. Daratumumabdan ölüme kadar geçen medyan süre 35 gündü.
Sonuç: Çalışmamızda relaps refrakter miyelom tedavisinde daratumumab ile literatür ile benzer şekilde olumlu yanıt oranları saptandı.

Authors: KOÇATAKAN Pınar , KÜÇÜK Aziz , KADI Zeki , ATASEVEN Hilmi 
Published: December 2021

Giriş ve Amaç: Kanıta dayalı tıp uygulamaları, endoskopik ultrasonografinin (EUS) pankreas kitlelerinin klinik değerlendirmesinde büyük bir etkisi olduğunu ortaya koymaktadır. EUS, transabdominal ultrason (US), bilgisayarlı tomografi (BT) veya manyetik rezonans görüntüleme (MR) ile elde edilenin çok ötesinde kabul edilen kalitede pankreasın yüksek çözünürlüklü görüntülerini sağlayabilmektedir. Bu sayede benign pankreas lezyonlarının ayrımı daha net biçimde ortaya konabilir, yaklaşık %10 hastanın operasyonsuz medikal tedavisi ile birçok yönden (hasta boyutu, hastane yönetimi, mali kaynak yönetimi vb.) fayda sağlanabilir.
Gereç ve Yöntemler: Literatür taraması sonrası Sosyal Güvenlik Kurumu Medula veri tabanından 2015-2019 yılları arasındaki Whipple ameliyat sayıları sektörel bazda elde edilerek incelenmiştir. Örneklem en çok EUS işlemi yapılan iki hastane verisi üzerinden basit dağıtım yöntemi ile 2019 yılı Whipple ve EUS işlemlerinin hastanelere maliyeti hesaplanmıştır.
Bulgular: Literatüre göre, %10 hastaya benign olmasına rağmen malign olduğu düşünülerek Whipple operasyonu uygulanmaktadır. EUS ile benign karakterde lezyonların daha net olarak tanımlanabileceği, bu sayede operasyon olmaksızın medikal takip ve tedavi yapılabileceği saptanmıştır. 2015-2019 yılı verilerine göre, Whipple operasyon sayılarında %10 azalma olması halinde, 5 yıl içinde 848 hastaya benign nedenlerle Whipple operasyonu yapıldığı düşünülmektedir.
Sonuç: Benign nedenlerle yapılan Whipple operasyonları geri ödeme kuruluşları açısından kaynak israfına neden olurken, tekrar başvuru oranlarının artmasına, hasta ve sağlık çalışanları açısından iş gücü kaybına ve hasta açısından komplikasyonlara ve hastanın yaşam kalitesinde düşmeye neden olmaktadır. 2019 yılı verilerine göre Türkiye’de yapılan Whipple operasyon sayılarından yola çıkarak EUS tanı yöntemi sayesinde benign pankreas kitlelerinin daha net tanımı yapılarak operasyon olmaksızın yapılan tedavileri ile yıllık 3.248.355,22 ₺ bir tasarruf sağlanabileceği öngörülmektedir.
Lattice thermal conductivity in isotope diamond asymmetric superlattices
Authors: Weng Hsu Kai , Nagakubo Akira , Watanabe Hideyuki , Ogi Hirotsugu 
Published: December 2021

Abstract
We study the lattice thermal conductivity of isotope diamond superlattices consisting of 12C and 13C diamond layers at various superlattice periods. It is found that the thermal conductivity of a superlattice is significantly deduced from that of pure diamond because of the reduction of the phonon group velocity near the folded Brillouin zone. The results show that asymmetric superlattices with a different number of layers of 12C and 13C diamonds exhibit higher thermal conductivity than symmetric superlattices even with the same superlattice period, and we find that this can be explained by the trade-off between the effects of phonon specific heat and phonon group velocity. Furthermore, impurities and imperfect superlattice structures are also found to significantly reduce the thermal conductivity, suggesting that these effects can be exploited to control the thermal conductivity over a wide range.

Abstract
We report the thermal conductivity (κ) of perovskite Sr1−x
(La0.5Na0.5)
x
TiO3 (0 ≤ x ≤ 1) and the thermoelectric properties of Nb-doped samples for x = 0.1 and 0.2. The κ of the solid solution shows a distinct minimum near the cubic-tetragonal phase boundary at x = 0.2, where the value becomes close to the minimum theoretical κ. Nb doping to x = 0.2 retains the high power factor found in Nb-doped SrTiO3, but also raises the κ to result in a thermoelectric figure of merit of 0.24 at 773 K.

Published: December 2021

Abstract
In large biomolecular systems such as protein complexes, there are huge numbers of combinations of inter-residue interactions whose comprehensive analyses are often beyond the intuitive processing by researchers. Here we propose a computational method to allow for a systematic analysis of these interactions based on the fragment molecular orbital calculations, in which the inter-fragment interaction energies are comprehensively processed by the singular value decomposition. For a trimer complex of SARS-CoV-2 spike protein, three-body interactions among residues belonging to three chains are analyzed to elicit a small number of essential interaction modes or networks crucial for the structural stability of the complex.

Résumé
Contexte : Il n’existe aucun outil par jalons reposant sur les CanMEDS-MF pour guider la rétroaction en supervision par observation directe (SPOD). Nous avons développé un guide pour soutenir la documentation de la rétroaction en SPOD en médecine familiale (MF) au Canada.
Méthode : La conception du Guide a été effectuée en trois phases avec la collaboration de cinq programmes de MF canadiens ayant minimalement un site d’enseignement francophone : 1) recension des écrits et étude des besoins; 2) élaboration du Guide de rétroaction SPOD; 3) mise à l’essai du Guide en contexte de simulation vidéo avec analyse de contenu qualitative.
Résultats : La phase 1 a démontré le besoin d’un guide narratif ayant pour but 1) de préciser les attentes mutuelles selon le niveau de formation du résident et le contexte clinique, 2) d’outiller et structurer le superviseur dans ses observations 3) de faciliter la documentation de la rétroaction. La phase 2 a permis d’élaborer le Guide, en formats papier et électronique, répondant aux besoins identifiés. En phase 3, 15 superviseurs ont utilisé le guide pour trois niveaux de résidence. Le Guide a été ajusté à la suite de cette mise à l’essai pour rappeler les phases de la rencontre clinique souvent oubliées durant la rétroaction (avant la consultation, diagnostic et suivi), et y suggérer des types de formulation à favoriser (questions stimulantes, questions de clarification, réflexions).
Conclusion : Issu de données probantes et d’une démarche de concertation, ce Guide outillera les superviseurs et résidents francophones canadiens dans leurs activités de SPOD en médecine familiale.

Period Ratio Sculpting near Second-order Mean-motion Resonances
Authors: Bailey Nora , Gilbert Gregory , Fabrycky Daniel 
Published: December 2021

Abstract
Second-order mean-motion resonances lead to an interesting phenomenon in the sculpting of the period-ratio distribution, due to their shape and width in period-ratio/eccentricity space. As the osculating periods librate in resonance, the time-averaged period ratio approaches the exact commensurability. The width of second-order resonances increases with increasing eccentricity, and thus more eccentric systems have a stronger peak at commensurability when averaged over sufficient time. The libration period is short enough that this time-averaging behavior is expected to appear on the timescale of the Kepler mission. Using N-body integrations of simulated planet pairs near the 5:3 and 3:1 mean-motion resonances, we investigate the eccentricity distribution consistent with the planet pairs observed by Kepler. This analysis, an approach independent from previous studies, shows no statistically significant peak at the 3:1 resonance and a small peak at the 5:3 resonance, placing an upper limit on the Rayleigh scale parameter, σ, of the eccentricity of the observed Kepler planets at σ = 0.245 (3:1) and σ = 0.095 (5:3) at 95% confidence, consistent with previous results from other methods.
Dynamics of Langmuir Wave Spectra in Randomly Inhomogeneous Solar Wind Plasmas
Authors: Krafft C. , Volokitin A. S. 
Published: December 2021

Abstract
Solar coronal and wind plasmas often contain density fluctuations of various scales and amplitudes. The scattering of Langmuir wave turbulence on these inhomogeneities modifies the properties of the radiated electromagnetic emissions traveling from the Sun to the Earth. This paper shows the similarities between the physical results obtained by (i) a model based on the Zakharov equations, describing the self-consistent dynamics of Langmuir wave turbulence spectra in a plasma with external density fluctuations, and (ii) a modeling, within the framework of geometric optics approximation, of quasi-particles (representing plasmon quanta) moving in a fluctuating potential. It is shown that the dynamics of the Langmuir spectra is governed by anomalous diffusion processes, as a result of multiple scattering of waves on the density fluctuations; the same dynamics are observed in the momenta distributions of quasi-particles moving in potential structures with random inhomogeneities. These spectra and distributions are both characterized by a fast broadening during which energy is transported to larger wavevectors and momenta, exhibiting nonlinear time dependence of the average squares of wavevectors and quasi-particle momenta as well as non-Gaussian tails in the asymptotic stage. The corresponding diffusion coefficients depend on the time and are proportional to the square of the average level of density (or potential) fluctuations. It appears that anomalous transport and superdiffusion phenomena are responsible for the spectral broadening.
New Searches for Continuous Gravitational Waves from Seven Fast Pulsars

Abstract
We conduct searches for continuous gravitational waves from seven pulsars that have not been targeted in continuous wave searches of Advanced LIGO data before. We target emission at exactly twice the rotation frequency of the pulsars and in a small band around such a frequency. The former search assumes that the gravitational-wave quadrupole is changing in a phase-locked manner with the rotation of the pulsar. The latter search over a range of frequencies allows for differential rotation between the component emitting the radio signal and the component emitting the gravitational waves, for example the crust or magnetosphere versus the core. Timing solutions derived from the Arecibo 327 MHz Drift-Scan Pulsar Survey observations are used. No evidence of a signal is found and upper limits are set on the gravitational-wave amplitude. For one of the pulsars we probe gravitational-wave intrinsic amplitudes just a factor of 3.8 higher than the spin-down limit, assuming a canonical moment of inertia of 1038 kg m2. Our tightest ellipticity constraint is 1.5 × 10−8, which is a value well within the range of what a neutron star crust could support.
