Trabajo, energía e información como configuraciones históricas: Notas para una metrología política del Antropoceno
Authors: Pasquinelli Matteo
Published: September 2024

El ensayo contribuye al debate sobre el papel de las métricas en la geoantropología. Este sostiene que el uso de la métrica de energía en el estudio del Antropoceno, entre otros fenómenos, debe ser observada en su relación con la metrología del trabajo y la productividad originada en la era industrial. Para aclarar este problema genealógico, el ensayo extiende el método de la “metrología histórica” (Witold Kula) a la noción de energía y, además, a la de información, que puede entenderse en sí misma como una métrica del conocimiento, el trabajo mental, la comunicación y la cooperación. Al revelar el nexo entre las abstracciones de la economía política y la tecnociencia, se destaca específicamente el rol de las máquinas (como la máquina de vapor y el telégrafo) como “mediadores epistémicos” (Norton Wise). El ensayo concluye defendiendo la inclusión de la metrología política en la necesaria caja de herramientas y “geopraxis” (Pietro Omodeo) del Antropoceno.
Удосконалена методика обробки каталогу TLE для виявлення маневру космічного апарату ближнього космосу
Authors: Ракушев Михайло , Богун Олексій
Published: September 2024

Метою статті є удосконалення методики виявлення непрогнозованих змін параметрів руху (маневрів) космічних апаратів за аналізом відкритих каталогів космічних об’єктів у форматі дворядкового набору елементів (Two-Line Element Set (TLE)) Командування повітряно-космічної оборони Північної Америки (North American Aerospace Defence Command (NORAD)). Удосконалення спрямоване на підвищення оперативності виявлення маневрів і збільшення кількості космічних апаратів (космічних об’єктів), що аналізуються. У дослідженні використані методи теорії польотів космічних апаратів, а саме щодо зміни елементів орбіти під дією керованої сили та прогнозування їх руху. Для виявлення маневрів космічних апаратів ближнього космосу на навколокругових орбітах, у TLE параметрах виділені інформативні параметри, що дають змогу проводити виявлення маневрів: момент часу, на який надано параметри орбіти, перша похідна середнього руху по часу, приведений балістичний коефіцієнт. Дієвість запропонованого підходу апробовано на космічних апаратах російської федерації «Барс М3» та «Канопус В3». Аналіз елементів TLE проводився на ділянках траєкторії за якими, з допомогою існуючого програмного забезпечення, прийнято рішення про здійснення маневру. Проведено поглиблений аналіз значення (змісту) приведеного балістичного коефіцієнту, який використовується в аналітичній моделі NORAD. За результатами аналізу розроблено удосконалену методику обробки каталогу TLE для виявлення маневру космічного апарату ближнього космосу. Використання удосконаленої методики дасть змогу позбутися недоліків в існуючій, а саме скоротити час, необхідний для проведення аналізу, та охопити весь каталог космічних об’єктів. Виявлення маневрування космічного апарату, що належить країні-агресору та державам, які її підтримують, дає змогу визначати зміну режиму застосування космічного апарату (наприклад, зміну району проведення космічної розвідки) та розкрити плани противника. Методика може бути використана під час аналізу та оцінювання космічної обстановки спеціалізованими підрозділами Збройних Сил України.
Improved Power Control Based Variable Speed Wind-Turbine DFIG under Hard Work Conditions: Application of Sliding Mode Theory
Authors: Itouchene Hichem , Boudries Zoubir , Amrane Fayssal
Published: September 2024

This paper introduces an efficient and simple power control for the Wind Energy Conversion System (WECS) based on the Doubly-Fed Induction Generator (DFIG). Due to the limitation performance of the conventional PI controller against DFIG parameters change and wind speed variation; the sliding mode theory is applied in order to overcome these drawbacks. To improve the performances of a WECS, robust and nonlinear control techniques, namely; Conventional Sliding Mode Control (C-SMC) and Third Order Sliding Mode Control (3O-SMC), were implemented to independently control the stator active and reactive powers. However, both techniques exhibited a chattering phenomenon, an undesirable phenomenon caused by discontinuous signals. To overcome this drawback and further enhance previous control techniques, an advanced Variable Gain Super Twisting Algorithm (VGSTA) is proposed and compared to SMC and 3O-SMC. Furthermore, to validate the effectiveness of the proposed VGSTA strategy in comparison to two previous control methods, the WECS was simulated and validates using the MATLAB/Simulink environment. The simulation results clearly demonstrated the superiority of the proposed VGSTA strategy over the previous SMC and 3O-SMC techniques. This was obvious in terms of both fast convergence velocity and reduce chattering phenomenon.
Polityka rachunkowości zakładów ubezpieczeń w obliczu przyjęcia Międzynarodowego Standardu Sprawozdawczości Finansowej 17 „Umowy ubezpieczenia”
Authors: Spigarska Ewa
Published: September 2024

Głównym celem artykułu jest pokazanie wpływu nowo przyjętego Międzynarodowego Standardu Sprawozdawczości Finansowej 17 „Umowy ubezpieczenia” (Dz.Urz. UE 416, dalej MSSF 17) na politykę rachunkowości zakładu ubezpieczeń. Przyjęte rozwiązania wpłyną na ujawnianie i wycenę kategorii finansowych posiadanych przez jednostkę ubezpieczeniową. MSSF 17 wprowadził wyraźny podział pomiędzy wynikiem na działalności ubezpieczeniowej a wynikiem na działalności inwestycyjnej. Odstąpiono od wykazywania przychodów na podstawie składek przypisanych w poszczególnych okresach. Skutki wpływu nowo przyjętych regulacji zostały pokazane na przykładzie Grupy PZU. Podstawą wyboru tej grupy jest fakt, że sporządza ona swoje skonsolidowane sprawozdanie finansowe opierając się na Międzynarodowych Standardach Rachunkowości i publikuje je jako jedyna grupa ubezpieczeniowa na Giełdzie Papierów Wartościowych w Warszawie. Na przykładzie Grupy PZU pokazano przykładowe zmiany w polityce rachunkowości wprowadzone na podstawie MSSF 17. W przyszłości planowane jest w celach porównawczych przeprowadzenie takich badań obejmujących międzynarodowe grupy ubezpieczeniowe.

Authors: Iwanicz-Drozdowska Małgorzata , Nowak Agnieszka K.
Published: September 2024

Jednym z wielu zadań banków, jako instytucji zaufania publicznego, jest zapewnienie bezpiecznego dostępu do usług bankowych. Jest to szczególnie trudne obecnie, ze względu na obserwowaną wysoką dynamikę zmian czynników rynkowych i regulacyjnych oraz postęp technologiczny. Zmiany te wpływają na postrzeganie banków oraz wpływają na ich konkurencyjność. Celem opracowania będzie ocena konkurencyjności sektora bankowego w Polsce (w podziale na sektor banków komercyjnych i spółdzielczych) na tle sektorów bankowych krajów UE oraz czynników aktualnie na nią wpływających, jak i mogących wpływać w przyszłości. Badanie obejmuje lata 2004–2022. Pojęcie konkurencyjności jest bardzo szerokie i może być różnie definiowane. Mając także na uwadze możliwości pozyskania publicznie dostępnych, porównywalnych danych, badanie skupi się na konkurencyjności podażowej, tzn. ocenie kondycji ekonomiczno-finansowej sektora bankowego. W badaniu zostanie wykorzystana metoda analizy wybranych mierników finansowych. Ocena zostanie poprzedzona przeglądem badań na temat wybranych czynników wpływających na konkurencyjność banków. Przeprowadzona analiza sytuacji ekonomiczno-finansowej pozwoli potwierdzić relatywnie dobrą kondycję polskiego sektora bankowego na tle innych państw UE, co nie wskazuje jednoznacznie na jego trwałą konkurencyjność. W podsumowaniu zarysowane zostaną perspektywy i wyzwania dla polskiego sektora bankowego.

The Sources of Fast Radio Bursts
Authors: Katz Jonathan I
Published: September 2024

This paper argues that repeating and apparently non-repeating Fast Radio Bursts are distinct classes of events produced by distinct classes of sources. As for conference proceedings, this paper reviews the evidence for that division, and then discusses the statistics of these classes. They differ in temporal/spectral space, spectral/duration space and rotation measure; the first two differences indicate different emission processes and the last indicates different environments. I discuss two of the many models of each class of source: black hole accretion discs for repeating FRB and hypermagnetized neutron stars (some observed to produce SGR) for apparently non-repeating FRB. Appendices suggest low cutoff frequencies of coherent emission that are consistent with these models and with known pulsars, and discuss the necessary conditions for acceleration of energetic particles.

A diferencia de los museos convencionales, los museos universitarios integran enseñanza, investigación y difusión del conocimiento, conectando el patrimonio artístico, tecnológico y documental con la comunidad académica. Aunque tienen un enorme potencial educativo y cultural, enfrentan desafíos como la falta de recursos y visibilidad. Se destaca así la necesidad de fortalecer las sinergias con otros departamentos e instituciones para revalorizar y ampliar el impacto de este patrimonio en la sociedad.
Legal Conflict in Isbat Nikah of Polygamous: Perspective of SEMA Number 3 Year 2018 and its Implications for Biological Justice
Authors: Sudrajad Achmad Sofyan Aji , Siregar Ibrahim , Harahap Zul Anwar Ajim
Published: September 2024

This article examines the legal conflicts associated with marriage validation (isbat nikah) in the context of polygamous marriages, particularly in relation to the Supreme Court Circular Letter (SEMA) No. 3/2018 and its implications for biological justice. SEMA No. 3/2018 mandates the rejection of isbat nikah applications based on informal or unregistered marriages to uphold legal certainty. The study employs normative research methods, incorporating conceptual, statutory, case, and comparative approaches. The conceptual approach is utilized to explore theories of biological and procedural justice. The statutory approach analyzes relevant legal provisions, with a focus on SEMA No. 3/2018 and marriage law. The case approach provides an in-depth analysis of two pivotal court decisions: the Cilacap Religious Court Decision No. 0430/Pdt.P/2019/PA.Clp and the Supreme Court Decision No. 223/K/Ag/2020. The comparative approach evaluates how these cases illustrate differing applications of the law. Data are analyzed qualitatively and descriptively to uncover and understand disparities in the application of justice. The study critically assesses the implications of SEMA No. 3/2018 on biological justice, highlighting the need for not only legal recognition of marriages but also robust protection of all parties' rights. The findings reveal significant deficiencies in the current legal framework, advocating for a more nuanced approach that reconciles legal recognition with the protection of biological rights. The research offers comprehensive recommendations for policymakers and legal practitioners aimed at enhancing legal provisions for individuals in unregistered polygamous marriages. These recommendations emphasize the importance of fostering dialogue among legal experts and updating regulations to ensure both procedural and substantive justice. Theoretical implications suggest that procedural and biological justice may conflict in the realm of isbat nikah in polygamous marriages, necessitating a more integrated and holistic legal approach to achieve substantive justice for all involved parties.

Monte Carlo Probability To Determine Attenuation Coefficient In Identifying The Selectivity Properties Of Near-Infrared-Based Materials
Authors: Trioclarise Rovika , Aminoto Toto , Kusumawati Yoni Rutiana , Lina Ratu Karel
Published: September 2024

Accurate attenuation coefficient measurements are able to display the nature of selectivity in an image. The methods used to measure the attenuation coefficient are Monte Carlo probability and linear regression models. This attenuation coefficient will appear if an image is taken in transmit mode. Selectivity properties are characterized by contrast ratios between different materials. In this transmission mode, if a near-infrared beam with a different wavelength is passed, it will produce different intensity values depending on the type of wavelength. According to Beer-Lambert's law, the intensity value will experience attenuation depending on the exponential function of the attenuation coefficient and thickness. By using Monte Carlo probability, we get the thickness value of a material per point. This thickness value is then displayed in image form. This thickness function is then used to display an image. The near-infrared wavelengths used are 780 nm and 808 nm. The results show that Monte Carlo probability shows more selectivity than the linear regression method. The wavelength of 808 nm can show more selectivity properties than 780 nm.

Temporal changes in visual organic enrichment indicators at an aquaculture site over mixed- and hard-bottom substrates
Authors: Pezzola C , Svensson SGB , Dunlop K , Sævik PN , Strohmeier T , Hansen PK , Keeley NB
Published: September 2024

Norway employs an environmental management system to assess benthic organic loading from aquaculture activities. Monitoring surveys, mostly performed through grab sampling, scrutinise responses to enrichment within soft-sediment macrofaunal communities. However, new methods and indicators of organic enrichment (IOE) need to be identified for mixed- and hard-bottom substrates. We used image characterisation to examine temporal changes in the abundance and coverage of benthic IOE on mixed- and hard-bottom substrates (organic pellets, sulphur-oxidising bacterial mats, opportunistic polychaete complexes [OPC], polychaete tube aggregations [PTA]) in relation to changes in organic deposition pressure through 1 yr of production at a rainbow trout farm on the western coast of Norway. Rates of organic deposition on the seafloor around the farm increased towards the end of the survey period as fish biomass increased. PTA were significantly associated with low levels of organic deposition and their abundance declined in 2 of the 3 study cages as the production cycle progressed. OPC coverage significantly increased with organic deposition and was greatest, 4 mo before the end of the production cycle. Organic pellet coverage closely followed the patterns of organic deposition on the seafloor, whereas bacterial mat coverage showed no relationship with deposition. Our findings provide new knowledge on the annual impact of organic enrichment on IOE beneath fish farms over mixed- and hard-bottom substrates, highlighting image characterisation methods as a means to improve benthic monitoring. This knowledge can contribute to the development of an environmental proxy to assess the enrichment stage around aquaculture farms placed over mixed- and hard-bottom areas.

The repression-dissent nexus in high-threat environments: Evidence from communist Romania
Authors: Surdea Vlad , Plopeanu Aurelian
Published: September 2024

We demonstrate the persistent role of political violence in shaping identities, making people from victimised communities more likely to engage in dissent even in high-threat environments. Theoretically, we argue that extreme repression instills anti-regime hostility that is curated and nurtured over time, making dissent the appropriate form of political behaviour when the opportunity arises, regardless of its consequences. Our research focuses on the Romanian Gulag, a network of labour camps, penal colonies and extermination centres used by the communist regime to suppress opposition, resulting in hundreds of thousands of deaths between 1945 and 1965. Using spatial regression and instrumental variable methods, we find that places with Gulag facilities had, on average, 5 times more people injured during the anti-communist revolution of 1989. Bayesian process tracing, conducted in a pathway case selected using causal forests, provides ample evidence in support of our theorised causal mechanism.
Not dead yet: cell death and survival in cancer and normal physiology
Authors: Green Douglas R.
Published: September 2024

For decades, we have assumed that all regulated cell death pathways have a dedicated “point of no return” that precedes death but after which cells are committed to die. The realization that this is often not the case represents what can be considered a paradigm shift in the field. Here we consider how cells can survive despite engagement of a cell death pathway and the consequences of a “near death experience” in cancer cells and possibly other physiological conditions.

Published: September 2024

Objective

In recent years, the lung-gut axis has received increasing attention. The oxidative stress and systemic hypoxia occurring in chronic obstructive pulmonary disease (COPD) are related to gut dysfunction. That suggests probiotics have a potential therapeutic role in COPD. In this study, we therefore evaluated the ameliorative effects of probiotics on COPD.

Methods

Searches were conducted in four electronic databases, including PubMed, Cochrane Library, the NIH clinical registry Clinical Trials. Gov and EMBASE. The data extracted was analyzed statistically in this study using StataMP17 software, with mean difference (MD) chosen as the effect size for continuous variables, and the results expressed as effect sizes and their 95% confidence intervals (CIs). Standardized Mean Difference (SMD) was used if the data units were different.

Results

We included three randomized, controlled, double-blind clinical trials and five randomized controlled animal studies. The results show that for lung function, probiotics improved %FEV1 in COPD patients (MD = 3.02, 95%CI: 1.10, 4.93). Additionally, in inflammation, probiotics increased IL-10 (SMD = 1.99, 95%CI: 1.02, 2.96) and decreased inflammatory markers such as TNF-α (SMD= -2.64, 95%Cl: -3.38, -1.90), IL-1β (SMD= -3.49, 95%Cl: -4.58, -2.40), and IL-6 (SMD= -6.54, 95%Cl: -8.36, -4.73) in COPD animals, while having no significant effect on C-reactive protein (MD = 0.30, 95%CI: -0.71, 1.32) in COPD patients. For lung structure, probiotics significantly reduced the degree of pulmonary collagen fibers deposition in COPD animals (SMD = -2.25, 95%CI: -3.08, -1.41).

Conclusion

Overall, probiotics may be an additional approach that can improve COPD. Further clinical trials are needed to evaluate the efficacy, safety, and impact factors of probiotics for COPD.

Objective

To explore the relationship between the exposure level of particulate matter 2.5 (PM2.5) and particulate matter 10 (PM10) in the air of pregnant women during preconception and first trimester of pregnancy and the risk of gestational diabetes mellitus (GDM).

Methods

The data of pregnant women delivered in 22 monitoring hospitals in Hebei Province from 2019 to 2021 were collected, and the daily air quality data of their cities were used to calculate the exposure levels of PM2.5 and PM10 in different pregnancy stages, and logistic regression model was used to analyze the impact of exposure levels of PM2.5 and PM10 on GDM during preconception and first trimester of pregnancy.

Results

108,429 singleton live deliveries were included in the study, of which 12,967 (12.0%) women had a GDM diagnosis. The prevalence of GDM increased over the course of the study from 10.2% (2019) to 14.9% (2021). From 2019 to 2021, the average exposure of PM2.5 and PM10 was relatively 56.67 and 103.08μg/m3 during the period of preconception and first trimester of pregnancy in Hebei Province. Handan, Shijiazhuang, and Xingtai regions had the most severe exposure to PM2.5 and PM10, while Zhangjiakou, Chengde, and Qinhuangdao had significantly lower exposure levels than other regions. The GDM group had statistically higher exposure concentrations of PM2.5 and PM10 during the period of preconception, first trimester, preconception and first trimester (P<0.05). Multivariate logistic regression analysis showed that the risk of GDM increases by 4.5%, 6.0%, and 10.6% for every 10ug/m3 increase in the average exposure value of PM2.5 in preconception, first trimester, preconception and first trimester, and 1.7%, 2.1%, and 3.9% for PM10. Moreover, High exposure to PM2.5 in the first, second, and third months of preconception and first trimester is associated with the risk of GDM. And high exposure to PM10 in the first, second, and third months of first trimester and the first, and third months of preconception is associated with the risk of GDM.

Conclusion

Exposure to high concentrations of PM2.5 and PM10 during preconception and first trimester of pregnancy can significantly increase the risk of GDM. It is important to take precautions to prevent exposure to pollutants, reduce the risk of GDM, and improve maternal and fetal outcomes.

Authors: Wang Jiao , Zhou Xiaokai , Su Yue , Chai Dongjian , Ruan Yaoyao , Wang Jinhua
Published: September 2024

Background

Previous studies have investigated the association between the haptoglobin rs72294371 polymorphism and coronary artery disease (CAD) risk, but the results are controversial and uncertain. Therefore, this study aimed to systematically review the literature on haptoglobin polymorphism and susceptibility to CAD.

Methods

PubMed, Embase, Web of Science, Cochrane Library, and Wanfang databases were used to identify relevant studies from their inception to April 2024. The pooled odds ratio (OR) with corresponding 95% confidence interval (CI) were used to assess the strength of the association. An OR value greater than one suggested an increased risk; otherwise, it suggested a protective risk.

Results

A total of 15 studies comprising 8,632 individuals (2,988 cases and 5,644 controls) were included. In the current meta-analysis, a significant association between haptoglobin polymorphism and CAD was found under recessive model (OR:0.74, 95% CI:0.60–0.92), dominant model (OR: 0.82, 95% CI: 0.71–0.95), homozygote model (OR: 0.70, 95% CI: 0.53–0.92), and allelic genetic model (OR: 0.80, 95% CI: 0.69–0.94). In the analysis stratified by ethnicity, a statistically significant association was observed in Asians rather than Caucasian population.

Conclusion

This meta-analysis indicates that haptoglobin polymorphism is associated with CAD susceptibility, especially in Asians.
Lighting the way: an economical alternative to feeder cell irradiation for T-cell expansion

Published: September 2024

A robust T-cell expansion process involves co-culturing T-cells with non-proliferating feeder cells combined with anti-CD3 antibody and IL-2. Although ionizing irradiation effectively inhibits feeder cell proliferation, the high operating costs limit cell therapy research to well-funded institutions. UVC, known for causing DNA damage-induced cell death and commonly used for environmental sterilization, presents a cost-effective alternative to ionizing irradiation for generating non-proliferating feeder cells. UVC irradiation of K562 artificial antigen presenting cells (aAPCs) resulted in significant DNA damage, evidenced by increased γ-H2AX phosphorylation within 15 minutes and elevated 8-OHdG levels at 24 hours. This indicates the occurrence of DNA double-strand breaks and oxidative damage. Following UVC irradiation, glucose uptake and ATP production were significantly reduced, whereas aCD3 retention at the surface of the cell increased twofold. Selective inhibition of glucose uptake and ATP production similarly enhanced aCD3 retention by approximately 10-fold and 6-fold, respectively. This suggests that UVC-induced energy deprivation dampens aCD3 internalization, potentially enhancing T-cell activation through prolonged aCD3 and T-cell receptor interaction. Tumor-infiltrating lymphocytes (TILs) expanded with UVC-irradiated PBMCs demonstrated comparable viability, expansion, immunophenotype, and effector function to those expanded with ionizing irradiation. UVC irradiation was equally effective in suppressing feeder cell proliferation and facilitating the expansion of functionally potent T-cells compared to traditional ionizing irradiation. Implementing UVC irradiation in T-cell expansion can significantly reduce costs, enhancing the accessibility and feasibility of cell therapy research across various institutions.

Published: September 2024

Construction using eco-friendly materials reduces environmental impact and promotes sustainable practices. This research uses sawdust and steel fibers to design sustainable concrete. The main goal is to improve mechanical properties and reduce embodied carbon emissions. This study examines the mechanical properties of concrete with different sawdust and steel fiber combinations to fill a gap in the literature. In this research synergistic effect of saw dust and steel fiber on concrete characteristics have been studied. The research also examines these pairings’ environmental benefits. This study used a response surface methodology (RSM) to design an experimental program and assess the effects of input variables (sawdust and steel fiber percentages) on output responses like compressive strength (CS), split tensile strength (STS), flexural strength (FS), modulus of elasticity (MOE), embodied carbon (EC), and eco-strength efficiency (ESE). Established testing methodologies and RSM provided an optimum prediction model based on specimen mechanical properties. Sawdust and steel fibers enhances concrete’s mechanical properties. Varying proportions of both materials were added in mix; sawdust (0%–12%) and steel fiber (0%–2%). The experimental findings suggest that the optimized composition achieved the following mechanical properties: 13.85 MPa compressive strength, 1.4 MPa split tensile strength, 3.67 MPa flexural strength, 18.027 GPa modulus of elasticity, 211.272 kg CO2e/m3 embodied carbon, and 0.065487 eco-strength efficiency. This research showed that the aims of improving mechanical properties and reducing embodied carbon were achieved. As per multi-objective optimization, optimal percentages of saw dust and steel fibers in concrete are 11.81% and 0.063% respectively. The investigation yielded many suggestions. To test the optimal blend composition of ecologically friendly concrete in real-world building projects, start with realistic projects. Finally, life cycle evaluations and cost studies are needed to determine the environmental and economic impacts of eco-friendly concrete compared to standard options.

Since the coronavirus disease 2019 (COVID-19) pandemic, wastewater-based epidemiology (WBE) has been widely applied in many countries and regions for monitoring COVID-19 transmission in the population through testing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in wastewater. However, the amount of virus shed by individuals over time based on the stage of infection and accurate number of infections in the community creates challenges in predicting COVID-19 prevalence in the population and interpreting WBE results. In this study, we measured SARS-CoV-2, pepper mild mottle virus (PMMoV), and human mitochondrial DNA (mtDNA) in longitudinal fecal samples collected from 42 COVID-19 patients for up to 42 days after diagnosis. SARS-CoV-2 RNA was detected in 73.1% (19/26) of inpatient study participants in at least one of the collected fecal specimens during the sampling period. Most participants shed the virus within 3 weeks after diagnosis, but five inpatient participants still shed the virus between 20 and 60 days after diagnosis. The median concentration of SARS-CoV-2 in positive fecal samples was 1.08 × 105 genome copies (GC)/gram dry fecal material. PMMoV and mtDNA were detected in 99.4% (154/155) and 100% (155/155) of all fecal samples, respectively. The median concentrations of PMMoV RNA and mtDNA in fecal samples were 1.73 × 107 and 2.49 × 108 GC/dry gram, respectively. These results provide important information about the dynamics of fecal shedding of SARS-CoV-2 and two human fecal indicators in COVID-19 patients. mtDNA showed higher positive rates, higher concentrations, and less variability between and within individuals than PMMoV, suggesting that mtDNA could be a better normalization factor for WBE results than PMMoV.

Introduction

The management of cancer patients follows a Diagnostic Therapeutic and Care Pathway (PDTA) approach, aimed at achieving the optimal balance between care and quality of life. To support this process, precision medicine and innovative technologies [e.g., next-generation sequencing (NGS)] allow rapid identification of genetic-molecular alterations useful for the design of PDTA-approved therapies. If the standard approach proves inadequate, the Molecular Tumor Board (MTB), a group comprising specialists from diverse disciplines, can step in to evaluate a broader molecular profile, proposing potential therapies beyond evidence levels I–II or considering enrolment in clinical trials. Our aim is to analyze the role of the MTB in the entire management of patients in our institute and its impact on the strategy of personalized medicine, particularly when all approved treatments have failed.

Materials and methods

In alignment with European and national guidelines, a panel of clinicians and preclinical specialists from our institution was defined as the MTB core team. We designed and approved a procedure for the operation of this multidisciplinary group, which is the only one operating in the Puglia region.

Results and discussion

In 29 months (2021–2023), we discussed and analyzed 93 patients. A total of 44% presented pathogenic alterations, of which 40.4% were potentially actionable. Only 11 patients were proposed for enrollment in clinical trials, treatment with off-label drugs, or AIFA (the Italian pharmaceutical agency for drugs)—5% funding. Our process indicators, time to analysis, and number of patient cases discussed are in line with the median data of other European institutions. Such findings underscore both the importance and usefulness of the integration of an MTB process into the care of oncology patients.
