Background: Administrative burdens have been identified as a major issue impacting patient care, professional practice, and the overall efficiency of healthcare systems. The aim of this study is to assess the administrative burden faced by Italian hematologists.
Methods: A cross-sectional survey that included both closed-ended quantitative questions and open-ended free text answer options was administered to 1,570 hematologists working with malignancies and members of Italian GIMEMA Foundation – Franco Mandelli ONLUS and the Italian Linfomi Foundation (FIL). The survey was conducted online from May 24 to June 30, 2023. Descriptive statistics were computed for the quantitative data to clearly summarize the responses and descriptive analysis of free text responses was carried out.
Results: Surveyed hematologists spend an average of 47.07% of their time on administrative tasks, with 63.22% (n = 110) of respondents reporting spending at least half of their time on these activities. More than half (57.47%, n = 100) reported that “Patient care” is the medical task most affected by a lack of time. Additionally, 55.17% (n = 96) reported experiencing burnout in the past 6 months, with filling out “Forms” being identified as the top contributing administrative task by 27.59% (n = 48) of respondents, followed by “Scheduling” (24.71%, n = 43) and “Managing IT system failures” (21.84%, n = 38). Nearly half of the surveyed hematologists (45.40%, n  =  = 79) identified patient care as the top priority requiring more time.
Conclusions: The study confirms that the administrative workload of hematologists has a significant impact on patient care, communication, and burnout risk, reducing the time available for patient care, leading to exhaustion and concern about clinical errors.

Published: July 2024

The assembly mechanisms of generalists and specialists have been extensively studied for prokaryotes but underexplored for microeukaryotes, the crucial players in marine ecosystems. In addition, the latitudinal gradient of biodiversity on the scale of the global ocean has been well documented, but is less studied at a regional scale. Here, we investigated plankton assemblages along a latitudinal gradient of a subtropical regional coastline using high-throughput sequencing of the 18S rRNA gene (rDNA) V4 region. We observed a trend of increasing diversity with decreasing latitudes in this provincial spatial scale, resembling the previously reported global-scale trend. Based on niche breadth, microeukaryotes in our samples were grouped into generalists, opportunists and specialists. Generalists were more influenced by selection than specialists, with temperature being an important factor. In addition, we found that dispersal limitation had a greater influence on the generalists than on the specialists. Interestingly, dinoflagellates, a major component in both generalist and specialist subcommunities, were important to stabilization in the generalist subcommunity. Chlorophyta, in contrast, had a crucial effect on network stability for specialists. Overall, this study verifies the latitudinal gradient of biodiversity at a mesoscale, and provides new insights into the ecotypic grouping and assembly mechanism of microeukaryotes. It also sheds light on the potential differential importance of Dinoflagellata and Chlorophyta.
Climate Obligations for International Shipping
Authors:   , Kerr Baine
Published: July 2024

This dissertation identifies climate obligations for the international shipping sector. If the sector were a country, it would be the eighth-largest source of greenhouse gas (GHG) emissions in the world. GHG emissions from shipping are regulated on a global level by the International Maritime Organization (IMO), a United Nations agency headquartered in London. Individual states also regulate the sector’s emissions in different ways. This dissertation examines what states and the IMO must do to reduce shipping’s climate pollution and how they can be held accountable.

It consists of four independent articles that examine a different aspect of climate obligations for shipping. The dissertation argues that the IMO legally committed itself to reducing GHG emissions from shipping consistent with the Paris Agreement’s global warming limitation goals. It finds that the IMO must implement GHG emission reductions in a way that gives preferences and transfers technology to small island developing states and least developed countries. It uses international environmental law principles to define shipping’s fair share of the overall mitigation burden as the sector’s highest possible ambition in light of its unique technological decarbonization capacity. Its further argues that states have a due diligence obligation to take all necessary measures to reduce shipping’s risk of climate harm; this obligation comes from customary environmental principles, human rights law, and the United Nations Convention on the Law of the Sea. Necessary measures vary by state, and include supporting ambitious and effective action at the IMO and unilateral actions to regulate ships and shipping companies.

The paper is focused on the evaluation of software and meth-ods for the visualization of thematic geospatial data with an emphasis on visual analysis in 3D. Meteorological data of the ALADIN forecast model were used to create visualizations. The first part focuses on the evaluation of selected software in terms of 3D visualization capa-bilities. The evaluation encompasses software tools such as geographic information systems, web-based solutions, and 3D computer graphics software. The result is a comparison of these software in terms of suitability for visual analysis in 3D, for example in terms of spatial data support, 3D visualizations, or analytical functions. The second part is focused on the presen-tation of four methods of 3D data visualization using horizontal planes for visualizing thematic data, including single plane, multiple planes without transparency, multiple planes with trans-parency, and multiple planes overlay. These methods were evaluated based on graphical var-iables, both the original ones defined by Jacques Bertin and those added later by other car-tographers, to achieve the most optimal visual analysis in 3D. The article concludes by high-lighting the advantages and disadvantages of the different visualization methods, and their specifics in terms of graphical variables. The importance of interactive visualization environ-ments for fully utilizing the potential of these methods is emphasized.

Published: July 2024

Предложен подход к построению нейросетевых моделей для расчета прочности наклонных сечений балок из сверхвысокопрочного бетона. Для нейронных сетей принята архитектура в виде многослойного персептрона с одним промежуточным слоем, которая является наиболее подходящей для моделирования нелинейной регрессии. Входящими переменными для расчета служат параметры, оказывающие влияние на прочность наклонных сечений, - размеры поперечного сечения, пролет среза нагружения, сопротивление бетона растяжению, коэффициент продольного армирования. Для повышения скорости сходимости алгоритма обучения нейронных сетей ко всем переменным применена минимаксная нормализация. Обучение осуществлялось квазиньютоновским методом с последующим отбором по показателям производительности нейронной сети. Проверку возникновения нежелательного эффекта переобучения производили контролем изменения значений среднеквадратичной ошибки. Точность расчета при помощи четырех отобранных нейронных сетей оказалась достаточно высокой. При этом все отобранные нейронные сети обнаруживают зависимость разрушающих поперечных сил от конструктивных характеристик балок и параметров нагружения, принятых в качестве входящих переменных.

Metal alloys like stainless steel, titanium, and cobalt-chromium alloys are preferable for bio-implants due to their exceptional strength, tribological properties, and biocompatibility. However, long-term implantation of metal alloys can lead to inflammation, swelling, and itching because of ion leaching. To address this issue, polymers are increasingly being utilized in orthopedic applications, replacing metallic components such as bone fixation plates, screws, and scaffolds, as well as minimizing metal-on-metal contact in total hip and knee joint replacements. Ceramics, known for their hardness, thermal barrier, wear, and corrosion resistance, find extensive application in electrochemical, fuel, and biomedical industries. This review delves into a variety of biocompatible materials engineered to seamlessly integrate with the body, reducing adverse reactions like inflammation, toxicity, or immune responses. Additionally, this review examines the potential of various biomaterials including metals, polymers, and ceramics for implant applications. While metallic biomaterials remain indispensable, polymers and ceramics show promise as alternative options. However, surface-modified metallic materials offer a hybrid effect, combining the strengths of different constituents. The future of biomedical implant materials lies in advanced fabrication techniques and personalized designs, facilitating tailored solutions for complex medical needs.

We have recently shown that cancer cells of various origins take up extracellular citrate through the plasma membrane citrate carrier (pmCiC), a specific plasma membrane citrate transporter. Extracellular citrate is required to support cancer cell metabolism, in particular fatty acid synthesis, mitochondrial activity, protein synthesis and histone acetylation. In addition, cancer cells tend to acquire a metastatic phenotype in the presence of extracellular citrate. Our recent study also showed that cancer-associated stromal cells synthesise and release citrate and that this process is controlled by cancer cells. In the present study, we evaluated the expression of pmCiC, fibroblast activation protein-α (FAP) and the angiogenesis marker cluster of differentiation 31 (CD31) in human cancer tissues of different origins. In the cohort studied, we found no correlation between disease stage and the expression of FAP or CD31. However, we have identified a clear correlation between pmCiC expression in cancer cells and cancer-associated stroma with tumour stage. It can be concluded that pmCiC is increased in cancer cells and in cancer-supporting cells in the tumour microenvironment at the later stages of cancer development, particularly at the metastatic sites. Therefore, pmCiC expression has the potential to serve as a prognostic marker, although further studies are needed.

Aims

Improved long-term survival has widened the treatment goals for adults with congenital heart disease (ACHD) by addressing parameters that impact mental well-being and exercise capacity. Depression, a frequent co-morbidity in ACHD, is linked to both. Whether successful treatment of depression also affects cardiac parameters is a matter of debate.

Methods

This prospective, cross-sectional, longitudinal study included N = 150 ACHD (mean age 35.2 ± 11.3 years, 57% male) at baseline (t0) and N = 114 at follow-up (mean follow-up: 4.8 ± 0.6 years; t1). Patients were interviewed using a structured clinical interview, and severity of depression was assessed using the Montgomery-Asperg Depression Scale (MADRS). Additional testing was performed using self-rating questionnaires concerning depression, anxiety and quality of life (QoL). Exercise capacity (VO2max) was assessed by symptom limited exercise testing.

Results

Of N = 33 patients diagnosed with depression at t0, N = 18 patients remitted and N = 15 were non-remitters. Remitters displayed significantly decreased anxiety (P = 0.013), improved global QoL (P = 0.002), and preserved VO2max (P = 0.958) at t1 compared to t0. This was associated with favourable health behaviour at t1 and stable body-mass-index. Contrarily, non-remitters reported further increased anxiety (P = 0.021) and no significant improvement in QoL (P = 0.405). VO2max declined significantly (P = 0.006) and body-mass-index increased (P = 0.004). Never-depressed patients showed no significant changes in anxiety (P = 0.415) or QoL (P = 0.211). VO2max decreased significantly (P < 0.001).

Conclusion

In ACHD, remission from depression is associated with better physical functioning, mental health, and QoL. The assessment and treatment of depression in ACHD emerges as an important clinical goal that should be included in a comprehensive multimodal treatment plan.
Carbon isotope chemostratigraphy of the Yucca Formation from the Solitario, Big Bend Ranch State Park, Texas
Authors: Biebesheimer E. J. , Suarez M. B.
Published: July 2024

Introduction: The Yucca Formation is a Lower Cretaceous sedimentary unit present in West Texas. Based on its relative stratigraphic position in the Cretaceous succession of West Texas, it is expected that the Yucca Formation is of Albian and/or Aptian age. It is also expected that the carbon isotope excursions associated with OAE 1a and OAE 1b should be identified in the Yucca Formation. The goals of this project are to 1. construct a carbon isotope chemostratigraphic record of the Yucca Formation, and 2. correlate the Yucca Formation with strata of similar age using chemostratigraphy.

Methods: 163 samples were collected from Big Bend Ranch State Park (BBRSP) to determine the δ13C value of bulk sedimentary organic matter.

Results: C-isotope values range from −27.02‰ to −18.42‰.

Discussion: Carbon isotope excursions (CIEs) that are associated with the Aptian-Albian Boundary are identified as well as CIEs associated with Oceanic Anoxic Events (1a and 1b). This allows us to conclude that the Aptian-Albian boundary is recorded within the Yucca Formation strata at about 71 m above the base of the section exposed in the Lower Shutup of the Solitario in Big Bend Ranch State Park. Regional correlation of the Yucca Formation to other chemostratigraphic records from other Cretaceous strata suggests that the Yucca Formation in BBRSP is time equivalent to the Sligo, Pine Island, James, Bexar, and a portion of the lower Glen Rose Formation on the Comanche Platform and to a portion of the lower Glen Rose Formation in Big Bend National Park.

The increased access to artificial intelligence (AI) applications has made it possible to develop more engaging and complex educational activities for students in different disciplines. This research explored expanding university students’ knowledge of scientific entrepreneurship skills using an Artificial Intelligence application. The students participated in a training experience using the conversational ChatGPT language model to generate narrative scripts for various topics on scientific discoveries and technological advances to create new products or services that offer cost-effective solutions based on science. The experience was designed employing the i4C model (identify, ideate, invent, inform). The study used a two-sample design with repeated measurements based on a pre-test and post-test. One hundred five graduate students from two master’s degree programs at the Bolivarian University of Ecuador participated during the 2022–2023 academic period. The results indicate that the students notably improved in acquiring the knowledge necessary for scientific entrepreneurial skills. The study concluded that applying AI ChatGPT with a narrative scripting strategy can create new learning opportunities for students.
