U-Pb zircon geochronology of high-grade charnockites– exploration of pre-Mesoproterozoic crustin the Mazury Complex area
Authors: Krzemińska Ewa , Łukawska Aleksandra , Bagiński Bogusław
Published: July 2023

Charnockites – i.e., orthopyroxene-bearing felsic rocks – were formed in a deep-seated dry environment, either under plutonic or high-grade metamorphic conditions. Most charnockites known from the crystalline basement of Poland appear to be of Mesoproterozoic age (1.50–1.54 Ga), cogenetic with the Suwałki Anorthosite Massif, and associated with mangerite and granite members forming the AMCG suite of the Mazury Complex. Genetically distinct rocks, characterised by the presence of anhydrous minerals, e.g., orthopyroxene and garnet, were also recognised along 592 m of the Łanowicze PIG-1 borehole section, within the AMCG suite. U-Pb geochronology by sensitive high resolution ion microprobe (SHRIMP) was used to date the complexly zoned zircons. The ages of crystallisation of the charnockite protoliths from various depths at 1837±7, 1850±9, 1842±6, and 1881±16 Ma makes these rocks the oldest dated crust within this part of the Polish basement. The Łanowicze PIG-1 borehole section bears components from neighbouring tectonic domains known from Lithuania: the West and Middle Lithuanian (WL/MLD) domains considered as a continental margin at 1.84–1.86 Ga and the fragmented Latvia-East Lithuania (LEL) domain, where the oldest continental crust was generated at c. 1.89– 1.87 Ga. The metamorphic zircon overgrowths document a high-grade event at 1.79 Ga and then constrained at 1.5 Ga. Dating of pre-Mesoproterozoic crust cryptic within the AMCG Mazury Complex provides valuable information on the nature of the pre-existing blocks formed during the long lasting Svecofennian orogeny.
Continuous magma mixing and cumulate separation in the High Tatra Mountains open system granitoid intrusion, Western Carpathians (Poland/Slovakia): a textural and geochemical study
Authors: Gawęda Aleksandra , Szopa Krzysztof , Włodyka Roman , Burda Jolanta , Crowley Quentin , Sikorska Magdalena
Published: July 2023

In this study the formation of the polygenetic High Tatra granitoid magma is discussed. Felsic and mafic magma mixing and mingling processes occurred in all magma batches composing the pluton and are documented by the typical textural assemblages, which include: mafic microgranular enclaves (MME), mafic clots, felsic clots, quartz-plagioclase-titanite ocelli, biotite-quartz ocelli, poikilitic plagioclase crystals, chemically zoned K-feldspar phenocrysts with inclusion zones and calcic spikes in zoned plagioclase. Geochemical modelling indicates the predominance of the felsic component in subsequent magma batches, however, the mantle origin of the admixed magma input is suggested on the basis of geochemical and Rb-Sr, Sm-Nd and Pb isotopic data. Magma mixing is considered to be a first-order magmatic process, causing the magma diversification. The cumulate formation and the squeezing of remnant melt by filter pressing points to fractional crystallization acting as a second-order magmatic process.
Redox conditions, glacio-eustasy, and the status of the Cenomanian–Turonian Anoxic Event: new evidence from the Upper Cretaceous Chalk of England
Authors: Jeans Christophers V. , Wray David S. , Williams C. Terry , Bland David J. , Wood Christopher J.
Published: July 2023

The nature of the Cenomanian–Turonian Oceanic Anoxic Event (CTOAE) and its δ13 C Excursion is considered in the light of (1) the stratigraphical framework in which the CTOAE developed in the European shelf seas, (2) conclusions that can be drawn from new detailed investigations of the Chalk succession at three locations in England, at Melton Ross and Flixton in the Northern Province where organic-rich ‘black bands’ are present, and at Dover in the Southern Province (part of the Anglo-Paris Basin) where they are absent, and (3) how these conclusion fit in with the present understanding of the CTOAE. The application of the cerium anomaly method (German and Elderfield 1990) at Dover, Melton Ross and Flixton has allowed the varying palaeoredox conditions in the Chalk Sea and its sediments to be related to the acid insoluble residues, organic carbon, δ18O (calcite), δ13C (calcite), δ13C (organic matter), Fe 2+ and Mn2+ (calcite), and P/TiO2 (acid insoluble residue). This has provided evidence that the initial stages of the δ13C Excursion in England were related to (1) a drop of sea level estimated at between 45 and 85 metres, (2) influxes of terrestrial silicate and organic detritus from adjacent continental sources and the reworking of exposed marine sediments, and (3) the presence of three cold water phases (named the Wood, Jefferies and Black) associated with the appearance of the cold-water pulse fauna during the Plenus Cold Event. Conditions in the water column and in the chalk sediment were different in the two areas. In the Northern Province, cerium-enriched waters and anoxic conditions were widespread; the δ13C pattern reflects the interplay between the development of anoxia in the water column and the preservation of terrestrial and marine organic matter in the black bands; here the CTOAE was short-lived (~0.25 Ma) lasting only the length of the Upper Cenomanian Metoicoceras geslinianum Zone. In the Southern Province, water conditions were oxic and the δ13C Excursion lasted to the top of the Lower Turonian Watinoceras devonense Zone, much longer (~1.05 Ma) than in the Northern Province. These differences are discussed with respect to (1) the Cenomanian–Turonian Anoxic Event (CTAE) hypothesis when the ocean-continent-atmosphere systems were linked, (2) limitations of chemostratigraphic global correlation, and (3) the Cenomanian–Turonian Anoxic Event Recovery (CTOAER), a new term to define the varying lengths of time it took different oceans and seas to recover once the linked ocean-continent-atmosphere system was over. The possibility is considered that glacio- eustasy (the glacial control hypothesis of Jeans et al. 1991) with the waxing and waning of polar ice sheets, in association with the degassing of large igneous provinces, may have set the scene for the development of the Cenomanian–Turonian Anoxic Event (CTAE).
In defence of invertebrate fossil taxonomy
Authors: Fedorowski Jerzy
Published: July 2023

Starting from a subjective viewpoint on the decreasing interest in invertebrate fossil taxonomy, this essay discusses its importance in palaeobiological studies exemplified with cases from the palaeobiogeography and palaeoecology of rugose corals, and aims at provoking a discussion on the topic. The possible causes of this negative declining trend include inherent problems of palaeontological taxonomy, and changing systems in science and higher education.
Lower Carboniferous solitary rugose corals from the Flett Formation of the Liard Basin, northwestern Canada vs. European and Asian Rugosa of the same geological age
Authors: Chwieduk Edward
Published: July 2023

The paper focuses on the taxonomic description of the lower Carboniferous (uppermost Tournaisian to middle Viséan) solitary rugose corals from bedded limestone and shale units in the Flett Formation in the Jackfish Gap (eastern Liard Range), northwestern Canada. The corals described herein include 12 species representing the genera Ankhelasma Sando, 1961, Bradyphyllum Grabau, 1928, Caninophyllum Lewis, 1929, Cyathaxonia Michelin, 1847, Ekvasophyllum Parks, 1951, Enniskillenia Kabakovich in Soshkina et al., 1962, Vesiculophyllum Easton, 1944 and Zaphrentites Hudson, 1941. Two of these species are new (Ankhelasma canadense sp. nov. and Ekvasophyllum variabilis sp. nov.) and 6 taxa are described in open nomenclature. The distribution and relative abundance of solitary Rugosa in Europe and the Liard Basin confirm the geographical proximity of those areas and the open marine communication between them during the early Carboniferous. It therefore represents an important contribution to the determination of the time of isolation of the western Laurussia shelf fauna from that of southeastern Laurussia, as well as the time of the possible emergence of species from southeastern Laurussia into the western Laurussia seas. Of particular importance here are cosmopolitan taxa and the timing of their disappearance from the fossil record.
A multi-analytical approach for the analysis of cation distribution in a aluminoceladonite structure
Authors: Kądziołka-Gaweł Mariola , Dulski Mateusz , Czaja Maria , Krzykawski Tomasz , Szubka Magdalena
Published: July 2023

In this paper cation arrangement in two samples of aluminoceladonite, emerald‑green and dark-green were studied by Mössbauer, Raman and X-ray photoelectron spectroscopies. The X-ray photoelectron spectroscopy (XPS) spectra obtained in the region of the Si2p, Al2p, Fe2p, K2p, and O1s core levels provided information, for the first time highlighting a route to identify the position of Si, Al, K, and Fe cations in a structure of layered silicates. The XPS analysis showed the presence of Al in tetrahedral and octahedral coordination while the K2p line indicated the possibility of K+ substitution by other cations in interlayer sites. Mössbauer spectroscopy provided information about crystal chemistry with respect to the local electronic and geometric environment around the Fe atom and to distortions of the polyhedra. It turned out that iron was located mostly in the cis-octahedra position wherein about 75% of iron appeared in the form of Fe 3+. The most preferred cation combinations around Fe corresponded to 3Fe 3+ ions and MgFe 2+Fe 3+/2MgFe 3+. Raman spectroscopy illustrated aluminium substitution in silicon and iron positions wherein the concentration of the aluminium determined the degree of structural distortion within the layered system. These isomorphic substitutions implied a typical band arrangement in the hydroxyl region, which has not been observed in celadonites so far.
A tyrannosaurid pedal ungual from the Williams Fork Formation (Campanian) of Colorado and its implications for the biogeography of Laramidian dinosaurs
Authors: Yun Chan-Gyu
Published: July 2023

A right theropod pedal ungual phalanx II-3 from the Campanian Williams Fork Formation of northwestern Colorado is described, and a combination of features, including the large size, tapering distal tip, robust and stout overall form, triangular cross-section, and a relatively flat ventral surface allows a confident referral to Tyrannosauridae Osborn, 1906. Although this specimen was found in a relatively southern state, the proximal articular surface of this ungual is similar to that of Gorgosaurus libratus Lambe, 1914, a taxon found in the northern state, Alberta. Although based on limited evidence, this may suggest that the range of tyrannosaurids considered endemic to the north of Laramidia extended farther south than previously thought.

The range of research topics includes: (i) geochemical and mineralogical studies of natural occurrences of the group, and attempts to relate their chemical composition to host lithology; (ii) detailed analysis of the hydrothermal alteration of CGM in various settings, with the aim of understanding element redistribution and the potential implications for ore formation. An ongoing series of high P-T experiments is providing quantitative information on the pressures, temperatures and melt water conditions under which the alteration assemblages have formed. Various spectroscopic techniques are being used to determine the structure of the CGM and to identify cation distribution in the structures.
Stratigraphy of the Albian–Cenomanian (Cretaceous) phosphorite interval in central Poland: a reappraisal
Authors: Machalski Marcin , Olszewska-Nejbert Danuta , Wilmsen Markus
Published: July 2023

Several closely-spaced phosphorite beds stand out at the Albian–Cenomanian transition in the mid-Cretaceous transgressive succession at the northeastern margin of the Holy Cross Mountains, central Poland. They form a distinctive condensed interval of considerable stratigraphical, palaeontological, and economic value. Here, we correlate the classical section at Annopol with a recently investigated section at Chałupki. We propose a new stratigraphic interpretation of the phosphorite interval, based on lithological correlations, Rare Earth Elements and Yttrium (REE+Y) signatures of phosphorites, age-diagnostic macrofossils, and sequence stratigraphic patterns. This interval has long been considered as exclusively Albian in age. However, new macrofossil data allow us to assign the higher phosphorite levels at Annopol and Chałupki, which were the primary target for the phosphate mining, to the lower Cenomanian. In terms of sequence stratigraphy, the phosphorite interval encompasses the depositional sequence DS Al 8 and the Lowstand System Tract of the successive DS Al/Ce 1 sequence. The proposed correlation suggests that lowstand reworking during the Albian–Cenomanian boundary interval played an important role in concentrating the phosphatic clasts and nodules to exploitable stratiform accumulations. Our conclusions are pertinent to regional studies, assessments of natural resources (in view of the recent interest in REE content of the phosphorites), and dating of the fossil assemblages preserved in the phosphorite interval. On a broader scale, they add to our understanding of the formation of stratiform phosphorite deposits.

Published: July 2023

Russia’s military aggression against Ukraine has undermined the global energy system, leading to high energy prices and increased concerns about the EU’s energy security EU leaders have adopted a number of laws and developed the REPowerEU plan to reduce dependence on Russian energy imports by accelerating the transition to clean energy and creating a more sustainable energy system in Europe. The plan includes measures to save energy, diversify supplies and rapidly replace fossil fuels with clean energy sources, as well as prioritizes equity and solidarity, taking into account the energy balances of each EU member state. It builds on the Fit for 55 proposals and supports the ambitious goal of achieving at least -55% net greenhouse gas emissions by 2030 and climate neutrality by 2050.The aim of the article is to study the use of renewable energy in the European Union, the application of autoregressive models to predict the development of renewable energy.The results and conclusions. As a result of the study, based on the methodology of transients, a model of change in the volume of investment in wind energy was developed in the form of a differential equation. It was proved that the transition process is stable, even with time constraints or reduction of investment in the development of wind energy over time it will return to a stable growing trend (which was obtained by means of bagatofactor autoregressive models).
Evaluation of the Smart Cities Listed in Smart City Index 2021 by Using Entropy Based Copras and Aras Methodology
Authors: Gelmez Emel , Özceylan Eren
Published: July 2023

Smart cities are included in the literature as a technology-based concept that has been on the agenda in recent years and whose framework is constantly changing with the changes in technology. There are different frameworks and indexes to define the smartness of a city. Smart City Index 2021 published by Institute for Management Development (IMD) and Singapore University of Technology and Design (SUTD) is one of the accepted studies in the world. In the report of Smart City Index 2021, 118 cities are evaluated in five criteria namely health & safety, mobility, activities, opportunities (work & school) and governance. To re-evaluate the cities and compare the results, a Multi-Criteria Decision Making (MCDM) process including Entropy based Complex Proportional Assessment (COPRAS) and Addivite Ratio Assessment (ARAS) methodology is applied in this paper. To prioritize the criteria, entropy weight method is used. 118 cities are ranked both technologically and structurally using the COPRAS and ARAS method. As a result of the analyses, according to these methods, the rankings of the smart cities are the same. Also, when technologically smart cities are listed, it is determined that the first three countries are Zhuhai, Shenzhen, Nanjing, and at the same time, Abu Dhabi, Chongqing, Hangzhou in terms of structurally.
The Complexity of the Current operational Environment and the Military Leader'S Ability to Adapt to its Ongoing Challenges
Authors: Badiu Marius-Iulian , Țică Laura-Alexandra
Published: July 2023

The current operational environment is characterized by a high degree of complexity, uncertainty, and ambiguity. Military leaders must be able to adapt to these ongoing challenges in order to succeed in their missions and achieve their objectives. One of the key challenges facing military leaders in the current operational environment is the rapidly changing nature of the threats they face. These threats can come from a wide range of sources, including state and non-state actors, terrorist organizations, and cyber attacks. Additionally, the proliferation of advanced technologies has created new vulnerabilities that military leaders must be able to address. Another challenge facing military leaders is the need to operate in a highly networked and interconnected environment. This requires a deep understanding of the complex systems that underpin modern warfare, as well as the ability to coordinate and collaborate with a wide range of stakeholders across multiple domains. Overall, the complexity of the current operational environment requires military leaders to be highly skilled, adaptable, and flexible. By developing these skills and leveraging new technologies and approaches, they can successfully navigate the challenges they face and achieve their objectives.

Military Actions Characteristics in Hybrid Operational Environments
Authors: Rațiu Aurelian , CÎrdei Alin , Herman Ramona
Published: July 2023

The theoretical approaches regarding the security/operational environment aimed at a multidimensional and integrative perspective, because its understanding requires not only analysis of the physical terrain, but also the perspective of the actors involved, and of the factors from the informational environment (including cyberspace) and those specific to the civilian population. The field of contemporary military confrontations is extremely difficult to analyze because of the dynamics of the phenomenon and internal processes, of the implemented technologies and, last but not least, as a result of the manifestation of VUCA (Volatility, Uncertainty, Complexity and Ambiguity) characteristics within them. But, the effort of scientific investigations was directed starting from the premise that the identification of the characteristics and of the factors specific to the future confrontational environment serves as a starting point in the approach of conceptual-doctrinal and operational adaptation/transformation of the military forces. An attempt was made to find the answer to the question: which are the conditions, circumstances and factors characteristic of the confrontational environment that influence the efficiency and coherence of the actions of the engaged capabilities?
Strategic Management in a Complex Geopolitical and Economic Context
Authors: Iancu Dumitru , Dinicu Anca
Published: July 2023

After the end of the COVID-19 pandemic, markets and economies were expected to stabilize in the sense of returning to average growth trends so that strategies and strategic management in organizations would be much more straightforward and predictable. Not only has the economic recovery not happened, with dramatic consequences, at least in terms of productivity, trade, and tourism, but developments on the international stage in the post-pandemic period, including the conflict in Ukraine, the failure of Silicon Valley Bank, Signature Bank, and First Republic Bank in the US, the takeover of Credit Suisse by UBS Bank in Switzerland, the social upheavals in France and Israel, do not support this stabilization, but on the contrary create fears of cascading events, contagion and widespread seizure of the international security environment. Thus, we consider the question: Is strategic management still relevant in a complex, fluid, and challenging context?
Landmines Between Banning and a Widespread Use
Authors: Andrei Constantin
Published: July 2023

The use of traps and landmines in military conflicts has its roots in antiquity. The evolution and continuous technological progress, recorded by humanity in all areas of economic and social life, had a special role in the development of new types of explosives with high destructive power, which in turn inevitably determined the diversification and improvement of landmines. Aware of the material damage, but especially of the loss of human life and trauma caused to personnel by landmines, most of the world’s states have agreed to ban their use. However, recent or ongoing military conflicts illustrate a widespread use of landmines. Despite this, the international community must make every effort to ban the use of landmines.

Severe acute myxedematous psychosis; rare complication of hypothyroidism
Authors: Guerrouj Hasnae , Ennibi Ghizlane
Published: July 2023

Background:

Severe acute myxedematous psychosis, or myxedema madness, is a rare and serious psychiatric complication of hypothyroidism. It is most often misdiagnosed, but it remains reversible after treatment with thyroid hormones.

Case Presentation:

We report a case of a patient without a known past medical history who underwent total thyroidectomy for papillary thyroid carcinoma. During her withdrawal from thyroid hormone therapy to perform a diagnostic radioiodine whole-body scintigraphy, she presented with anxiety, delirium, and hallucinations, culminating in a suicide attempt. Laboratory testing revealed a high sensible-thyroid stimulating hormone (TSH) value of 35 µIU/ml. The patient was hospitalized in a psychiatric unit, where she received antipsychotic medication and was started on thyroid hormones. After a week, there was a dramatic improvement. Psychiatric symptoms were completely gone a month later justifying the discontinuation of antipsychotics. Recombinant human TSH (rh-TSH) was necessary injected before radioiodine therapy to avoid thyroid hormone therapy suppression and to prevent a second episode of acute psychosis.

Conclusion:

rh-TSH interest is both in the pre Ira therapy stimulation and for the post-treatment monitoring of patients with thyroid cancer, and helps avoiding hormonal treatment suppression.

Published: July 2023

On the Angara River there is a reservoirs cascade of four hydroelectric power stations, and in the lower reaches it is planned to build the Nizhneboguchanskaya HPS. On the other hand, at present there is a significant gap in the studies of the Angara lower section, especially in zoobenthos. The material for the study was zoobenthos samples taken in the coastal zone in August 2022 at 11 river stations in a section from 445 km to 9 km from the mouth. Biotopes of zoobenthos are represented mainly by pebble-sandy soil with varying degrees of silting. The benthic fauna of the Angara River was gammarid-chironomid in nature; oligochaetes were found everywhere, but in small numbers. 87 species and taxa of a higher rank had been identified, the largest number of species (37) was noted among the chironomid larvae of Orthocladiinae and Chironominae. The quantitative advantage (more than 60% of the abundance and biomass) belonged to amphipods. Chironomids predominated over amphipods only on silty bottoms; in the river section, in general, they accounted for 24% of the abundance and 10% of the biomass of benthic communities. The Shannon species diversity index was relatively low and amounted to 2.3 bit/ind. general in the section. The lower reaches of the river were characterized by the highest species diversity, but the lowest number of benthic invertebrates. The total number of zoobenthos in the studied area was 2,9 thousand ind/m2, biomass – 14,6 g/m2, in the lower reaches of the river the number decreased to 1.7 thousand ind/m2, biomass – up to 4 g/m2. An integrated approach was used to assess the water quality of the Angara benthic communities, that includes the analysis of 8 bioindication indices: Goodnight (G), Woodiwiss (TBI) and saprobity (S) indices (recommended by the Russian regulatory document); indices FBI, BMWP, ASPT (recommended by the European Water Framework Directive); the Balushkina chironomid index (K) and the Shannon species diversity index. The fundamental criterion for the selection of indices was the level of development of indicator taxa. The complex assessment revealed the trend of improving water quality to the mouth of the river. This trend is expressed in the consistent dynamics of the TBI, BMWP, ASPT indices, which can be recommended for assessing the ecological state of the Angara River and other watercourses in the region. The water quality corresponded to Class III (Polluted) with a tendency to improve at the mouth to Class II (Slightly polluted).

El presente trabajo es un análisis sobre los elementos visuales presentes en la vida diaria de los individuos en el contexto social en el que se desenvuelven y en los espacios particulares con los cuales tienen que interactuar. El hombre siempre ha necesitado expresarse a través de la imagen y es así como desde la antigüedad se ha comunicado. Le ha sido necesario contar con elementos que le sirvan como guías para ubicarse y desplazarse de manera más rápida y sencilla. Dichos elementos visuales se encuentran clasificados dentro de la señalización o la señalética, siendo ahí donde inicia la diferencia entre ambos conceptos y su importancia en la sociedad.

Housing and settlements are basic human needs that are important factors in improving human dignity and the quality of a prosperous life in a just and prosperous society. The problem of slums which are mostly inhabited by the poor is a complex and intertwined phenomenon because it has long been a social problem in the community. One of the efforts of the Surabaya City Government to reduce uninhabitable housing is through the Slum Areas Social Rehabilitation Program (RSDK).Research on the Evaluation of the Slum Region Social Rehabilitation Program for Improving the Quality of Life of Residents was carried out to describe the extent of the Evaluation and Impact of the Implementation of the RSDK Program, using descriptive qualitative research methods based on the criteria of Effectiveness, Efficiency, Adequacy, Equality, Responsiveness, and Accuracy. The results of this evaluation indicate that in general, the Program Implementation was sufficient to meet the criteria targeted at the implementation program. In terms of efficiency, program implementation still has shortcomings due to the minimum timeframe specified and also the implementation process that is appropriate to the cost per stage. Adequacy is judged by the success of the development is still low due to complaints from some program beneficiaries. The similarity is seen based on the costs incurred for the Construction of Home Improvements have been carried out fairly. The level of community responsiveness related to program implementation is quite good because of the role of the local community in helping the program implementation process. The accuracy of the program implementation related to the results or program objectives is in accordance with what is desired. The physical impact that occurs with the construction of uninhabitable housing improvement programs can help the development of environmental conditions in the communities living in slums. Meanwhile, the social impact that occurs is to bring up the value that is useful and useful for the needs of people's lives.

Published: July 2023

A modified and improved inductive inferential approach to evaluate item discriminations in a conditional maximum likelihood and Rasch modeling framework is suggested. The new approach involves the derivation of four hypothesis tests. It implies a linear restriction of the assumed set of probability distributions in the classical approach that represents scenarios of different item discriminations in a straightforward and efficient manner. Its improvement is discussed, compared to classical procedures (tests and information criteria), and illustrated in Monte Carlo experiments as well as real data examples from educational research. The results show an improvement of power of the modified tests of up to 0.3.

The incidence of second primary malignancies (SPM) in long-term survivors of multiple myeloma (MM) is increasing because of increased life expectancy. We retrospectively analyzed the risk factors for SPM in patients with MM after autologous stem cell transplantation (ASCT) before and after the introduction of proteasome inhibitors and immunomodulatory drugs (IMiDs). In total, 2,340 patients newly diagnosed with MM who underwent ASCT between 1995 and 2016 were enrolled in this study. Forty-three patients developed SPM (29 solid, 12 hematological, and 2 unknown tumors), with cumulative incidence rates of 0.8% and 2.5% at 24 and 60 months, respectively. The cumulative incidence rates of hematological and solid SPM at 60 months were 0.8% and 1.8%, respectively. The overall survival (OS) rate at 60 months after ASCT was 62.9% and the OS rates after the diagnosis of SPM at 24 months were 72.2% for hematological SPM and 70.9% for solid SPM. Multivariate analysis revealed that the use of IMiDs (P=0.024) and radiation (P=0.002) were significant independent risk factors for SPM. The probabilities of developing SPM and death due to other causes (mainly MM) at 60 months were 2.5% and 36.5%, respectively, indicating that the risk of SPM was lower than that of death from MM. Furthermore, SPM between the pre-novel and novel agent eras (ASCT between 2007 and 2016) groups significantly increased (1.9% vs. 4.3% at 60 months; P=0.022). The early occurrence of SPM after ASCT should be monitored cautiously.
