Authors: Calderón López Christopher Nelson , Acosta Vinueza Lola Yesenia , Rivadeneira Jorge Elías
Published: May 2024

El trastorno afectivo bipolar es una patología mental muy frecuente que se caracteriza por cambios en el afecto con alternancia de episodios maníacos y depresivos separados por periodos eutímicos y muchas veces con ciclaciones rápidas que entorpecen el curso y el tratamiento. El presente es un estudio cuasi experimental, longitudinal y descriptivo cuyo objetivo fue determinar la evolución clínica con el tratamiento de oxigenoterapia hiperbárica como terapia complementaria. Se presenta un caso de una mujer con patología psiquiátrica, trastorno afectivo bipolar tipo II, que fue admitida al programa ambulatorio de oxigenoterapia de la Unidad Hiperbárica de Investigación Universitaria, con un seguimiento de 16 semanas de los síntomas, usando la escala de impresión clínica global modificada para el tratamiento bipolar (CGI-BP-M) semanalmente, además de una evaluación inicial y final aplicando el inventario de depresión de Beck junto a la lista de verificación de la hipomanía-32 (HCL-32). A pesar de la poca significancia estadística y la aparición de variables no controladas que incidieron en la culminación del número total de sesiones propuestas, se logró evidenciar cambios favorables durante el periodo de seguimiento sobre todo en algunos aspectos clínicos distintos a los evaluados con las escalas de medición

Authors: M. Taib Maisarah , Fauzaman Jusmawati
Published: May 2024

Background: The expression of personality in work context may differ in general context and the transportation of western-based personality measures to non-western cultures have been found problematic in terms of their psychometric soundness. Objective: This research was conducted with the aim to develop an indigenous work-based personality inventory using the indigenously explored Malay personality taxonomy (Nefarious, Emotionality, Virtues, Indulgence, eXtraversion, and Accommodative factors; abbreviated as NEVIXA). Methods: The test was developed using American Psychological Association (APA) Standards of Educational and Psychological Testingâ€™s (2014) four main phases of test development: (1) Test conceptualization, (2) Test construction, (3) Test tryout and item analysis, and (4) Test validation. This preliminary finding, however, discussed results up to Phase 3 of the test developmentâ€”test tryout and item analysis phase. Results: Item response theory (IRT) analysis using Samejimaâ€™s graded response model (GRM) of IRT for polytomous items recorded a total of 286 items (143 English items and 143 Malay items) with appropriate item discrimination index and reliability values, namely, the Cronbach alphas and Equivalence coefficients. Conclusion: Further efforts are needed to validate the items for a full development of an indigenous work-based personality test that can be used for work-related applications.

Peanut smut, caused by Thecaphora frezzii Carranza & J.C. Lindq., is an emerging threat for the global peanut industry. The disease’s destructive potential can be exemplified by pod incidence values as high as 70% and yield losses reaching 30%. Because fungicides have shown moderate but highly variable levels of control levels, development and deployment of smut resistant cultivars are the best strategies for disease management. Screening for smut-resistant germplasm requires years of field trials and is currently the only option for breeders because genetic markers for resistance have not yet been developed. The objectives of this study were to perform whole genome sequencing (WGS) on populations developed for smut resistance mapping and subsequently fine map discovered QTL associated with smut resistance. An expedited strategy was employed by phenotyping in the F3 generation. We phenotyped 200 families with 3 plants per family for smut resistance in infested fields during the 2019/2020 season in General Deheza (32°45′23″S 63°47′20″W), Argentina. Each individual was sequenced using iGenomXRipTide library preparation and Illumina NovaSeq sequencing to yield approximately 1 times genome coverage. Analysis of the phenotype and genotype data using Khufu resulted in the identification of a single major smut resistance QTL on chromosome 12 (B02). Chromosome level genome sequences were assembled for the resistant parent (Ascasubi) and susceptible parent (Granoleico) using PacBio HIFI sequencing. A validation population was sequenced using Khufu to validate the QTL region and analysis confirmed the major locus on chromosome 12. The identified variation will be used to develop smut resistant varieties quickly using molecular assisted breeding strategies.
Proposed Person-Specific Treatment Pathway for Cardiovascular Metabolic Renal Disease & Implications to Population Health
Authors: Attanasio Michael , Santanna Megan
Published: May 2024

The WHO considered Diabetes a global epidemic in its first Global Report on Diabetes published in 2016.1 Diabetic treatment standards of care have shifted immensely in the previous decade with the emergence of new therapeutic classes and important evidence from Cardiovascular and Renal Outcomes Trials (CVOT). These studies have helped to draw connections that newer therapies are not simply reducing hyperglycemia but lessen risk of atherosclerotic events, heart failure and worsening renal function. Through this meaningful research, there is a growing body of evidence to begin approaching the treatment of diabetes as a cardiovascular-metabolic-renal disease. There is much work to be completed in this area as there is a notable content gap that directly tackles both the complexities of disease and comprehensive therapeutic treatment implementation in diabetes patients. Data overload and rapid changes to standards of care have left providers, payers, and PBM’s with unclear direction forward. This paper works to highlight the importance of the previous decade of research including the CVOT outcomes, illustrates an optimized person-specific pathway for therapeutic treatment of the cardiovascular metabolic renal disease patient and assesses the implications to population health including care delivery and total cost of care. Our proposed pathway joins guideline-based treatment and CVOT data to provide a practical application to implement in incremental patient care. Finally, provides a real-world framework implementation plan of a multi-interdisciplinary team for a value-based outcome driven initiative.
Social Support and Motivation in STEM Degree Students: Gender Differences in Relations with Burnout and Academic Success
Authors: Horrocks Phoenix T. M. , Hall Nathan C.
Published: May 2024

Existing research underscores the importance of both social-environmental factors (e.g., social support) and psychological factors (e.g., motivation) as buffers against attrition, low performance, and psychological maladjustment in science, technology, engineering, and math (STEM) degree programs. Female STEM students in particular contend with additional academic challenges that can hamper their motivation and performance. This study investigated the relations between social support (personal vs. academic) and well-being, persistence, and academic outcomes as mediated by self-determined motivation and moderated by gender. Structural equation modelling with 221 STEM undergraduates showed significant indirect paths between personal support and STEM career intentions via autonomous motivation. Multigroup analyses further showed male STEM students to benefit more from both personal and academic supports, as well as from greater autonomous motivation, with the academic risks of controlled motivation observed primarily for female STEM students. Implications for motivationally supportive teaching practices in STEM degree programs are discussed.

Authors: King Meredith , Wootton Sally L. , Ong Robert , McKeough Zoe J. , Dennis Sarah
Published: May 2024

Background: The incremental step test (IST) could potentially be used to prescribe exercise training in people with COPD. Objective: To examine the relationship between IST total step count (ISTC) and 6MWT distance (6MWD) to determine whether an appropriate walking training prescription can be inferred from the ISTC. Methods: People with COPD were recruited after a PR assessment (including two 6MWTs) and performed one IST. Pearson’s correlation coefficient (r) assessed the relationship between ISTC, 6MWD and other independent variables. An estimated 6MWD equation from ISTC was derived through stepwise linear regression analysis and Bland Altman plots determined agreement between predicted 6MWD based on ISTC and actual 6MWD. Results: Thirty participants (mean [SD] age 74 [7] and FEV1 58 [21] % predicted) completed testing. Mean [SD] ISTC and 6MWD was 86 (40) and 462 (94) metres respectively. A strong positive correlation was found between ISTC and 6MWD (r = 0.82, p<0.001). ISTC and height (r = 0.32, p <0.001) and age (r = 0.22, p <0.003) were weakly associated. The estimated 6MWD equation from the stepwise regression was 6MWD (m) = 1.92 (ISTC) + 296.7. Conclusion: The IST could estimate 6MWD in people with COPD as the tests are strongly correlated.

Authors: Abdullah Abdul Samad A. , Faisal Hassan A. , Awad Khairullah M.
Published: May 2024

Objective: The study aimed to explore the effects of different planting medium on the growth of date palm Hillawi cv. offshoots. Methods: The experiment included two main factors: the first factor was planting media, consisting of three treatments: field soil, zeolite + field soil (in a 2:1 ratio), and zeolite + sand (in a 2:1 ratio). The second factor was cultivation method, comprising three methods: traditional planting, container planting (using pots), and planting in lined holes with a layer of agricultural polyethylene (nylon). Results: Planting medium significantly influenced the growth of the offshoots. Specifically, planting media with zeolite and sand exhibited significant improvements in leaf length, dry matter content, leaf area, root count, root length, and diameter compared to the control group. Conversely, the zeolite-field soil combination exhibited a marked increase in moisture content. Additionally, electrical conductivity (EC) within the planting media was notably higher in the control condition featuring only field soil. The study also found that the chosen cultivation method significantly influenced the growth of the offshoots. The lined holes method displayed significant advantages in leaf length, dry matter content, leaf area, root count, root length, root diameter, and moisture content within the planting media, compared to the traditional approach. Conversely, the traditional method resulted in higher EC within the planting media. Conclusions: The study reveals significant effects of cultivation medium, method, and their interaction on various growth parameters of date palm offshoots. This study recommends the lined-hole planting method and zeolite-infused medium for enhanced offshoot growth.

Objectives: Effect of hrmone (BR)and (SAP) on the biochemistry traits of okra Abelmoschus Esculentus L.under two different irrigation periods. Mothods: The experiment was conducted in one of the private fields north of Basrah for the growing season 2022-2023. It was included a study of the effect of three factors:the hormone brassinolide(BR) at three concentrations (0,3,6) mg/l and the polymer hydrogel(SAP) at concentrations (0,50,100) g/m2 soil, irrigation periods (3,6) days, and their double and triple interactions. It was designed according to (R.C.B.D.) with three replicates for each treatment and the least significant difference test was adopted at the probability level (0.05( Results: Showed that the treatment of plants with the hormone led to a significant increase in the characteristics of chlorophyll, carbohydrates and stability of the membranes at a concentration of 6 mm / L, and led to a decrease in the concentration of proline, hydrogen peroxide and MDA and the effect of the polymer led to a significant increase in the total chlorophyll content, carbohydrates and membrane stability at a concentration of 100 g / m2 soil. While it reduced the concentration of proline, hydrogen peroxide and MDA as well. Irrigation periods of 3 days showed a significant effect on the carbohydrate content of the leaves, while the differences were negligible for the rest of the traits, and the two-way interactions showed a significant effect on all the studied traits. Conclusions: The triple interactions led to a significant increase in all studied traits at a hormone concentration of 6 mg/L and a polymer at a concentration of 100 g/m2 soil and an irrigation period of 3 days compared to the control treatment and an irrigation period of 6 days except for proline, MDA and hydrogen peroxide.

Authors: Abdalreda Estabraq Mohammed , Mohammed Liqaa Hussein , Mohammadali Mushtak Talib , Hasan Sarah Tareq
Published: May 2024

Objectives: This study was carried out to investigate the effectiveness of some nanoparticles in inhibiting the growth of the root knot nematode. Methods: This study was carried out to investigate the effectiveness of aluminum oxide Alo-NPs and silver Ag-NPs, and chemical nematicides (Velum prime and Furadan granules), in inhibiting the growth of the root knot nematode (Meloidogyne incognita) on two different types of eggplant cultivars, Barcelona and Thuraya. Results: The result obtained indicated that chemical nematicides and nanoparticles were highly effective in lowering the nematode invasion level expressed as number of knots per root and a gall index based on a 0-5 scale. Velum prime at concentrations of 300 and 400 ppm was the most effective and gave 0.67 and 0.17 knots/root average on both eggplant cultivars, respectively. In addition, the ALO-NPs treatment reduced infection to 1.17 knots/root compared to initial infection of 37.33 knots/root. The use of Ag-NPs at the concentration of 4000 ppm reduced infection to a low average of 2.83 knots/root for both eggplant varieties. All treatments average reduced the gall index to 0.95 (cv. Barcelona) and 1.20 (cv. Thuraya) compared to 3.33 and 4.00 for the infected non-treated controls, respectively. Conclusions: Nanoparticles have a role in controlling root-knot galls as alternatives to chemical pesticides that are dangerous to the environment and humans, and reducing the number of galls on the plant indicates the inhibition of eggs and second stage juveniles (J2).

Authors: Azeez Zahraa Falah , Falhy Majida M. Abid
Published: May 2024

Objectives: Isolation Aspergillus tamarii, Cladosporium herbarum, and Verticillium lecanii fungi from naturally infected Culex pipiens and Anopheles stephensi insects were morphologically and molecularly identified. Methods: In this study, populations of mosquitoes were cultured and examined to determine fungal infection and evaluated as potential agents against C. pipiens and A. stephensi. Results: A variety of fungal isolates demonstrated differing degrees of pathogenicity 24 hours after treatment against C. pipiens and A. stephensi eggs, four-instar mosquito larvae, and adults. and as a biological control, it was found that the fungal suspension of each of the used fungi affected the life roles of the two mosquitoes. as it was more than the fungus suspension A. tamarii, Cl. herbarum on V. lecanii. The highest percentage of eggs mortality were (36.72, 48.97) %, (29.14, 42.25) %, and (24.45, 35.70) % of C. pipiens and A. stephensi when using the highest concentration of 1*105 spore/ml, 3*105 spore/ml and 2*105 spore/ml of fungicide A. tamarii, C. herbarum, V.lecanii and respectively after 24 hours. The highest mortality rate was for the fourth larval stages, and the mosquito A. stephensi is more sensitive to type C. pipiens infection., as, in order (75.6, 67.19, 56.8) %, (74.18, 59.81, 50) %, and (65, 52,42.71) %. Conclusions: Results highlight the significance of a mosquito's natural fungal opponent. All isolates had an impact on adults and larvae, although they were less successful against eggs. Both have the potential to develop, particularly against the larvae of the primary arbovirus, malaria, and lymphatic filariasis vectors, A. stephensi, and C. pipiens.

Published: May 2024

OBJECTIVE

Despite 51.2% of medical school graduates being female, only 29.8% of neurosurgery residency applicants are female. Furthermore, only 12.6% of neurosurgery applicants identify as underrepresented in medicine (URM). Evaluating the entry barriers for female and URM students is crucial in promoting the equity and diversity of the neurosurgical workforce. The objective of this study was to evaluate barriers to neurosurgery for medical students while considering the interaction between gender and race.

METHODS

A Qualtrics survey was distributed widely to US medical students, assessing 14 factors of hesitancy toward neurosurgery. Likert scale responses, representing statement agreeability, converted to numeric values on a 7-point scale were analyzed by Mann-Whitney U-test and ANOVA comparisons with Bonferroni correction.

RESULTS

Of 540 respondents, 68.7% were female and 22.6% were URM. There were 22.6% male non-URM, 7.4% male URM, 53.5% female non-URM, and 15.2% female URM respondents. The predominant reasons for hesitancy toward neurosurgery included work/life integration, length of training, competitiveness of residency position, and perceived malignancy of the field. Females were more hesitant toward neurosurgery due to maternity/paternity needs (p = 0.005), the absence of seeing people like them in the field (p < 0.001), and opportunities to pursue health equity work (p < 0.001). Females were more likely to have difficulties finding a mentor in neurosurgery who represented their identities (p = 0.017). URM students were more hesitant toward neurosurgery due to not seeing people like them in the field (p < 0.001). Subanalysis revealed that when students were stratified by both gender and URM status, there were more reasons for hesitancy toward neurosurgery that had significant differences between groups (male URM, male non-URM, female URM, and female non-URM students), suggesting the importance of intersectionality in this analysis.

CONCLUSIONS

The authors highlight the implications of gender and racial diversity in the neurosurgical workforce on medical student interest and recruitment. Their findings suggest the importance of actively working to address these barriers, including 1) maternity/paternity policy reevaluation, standardization, and dissemination; and 2) actively providing resources for the creation of mentorship relationships for both women and URM students in an effort to create a workforce that aligns with the changing demographics of medical graduates to continue to improve diversity in neurosurgery.

Published: May 2024

OBJECTIVE

Tranexamic acid (TXA) is an FDA-approved antifibrinolytic that is seeing increased popularity in spine surgery owing to its ability to reduce intraoperative blood loss (IOBL) and allogeneic transfusion requirements. The present study aimed to summarize the current literature on these formulations in the context of short-segment instrumented lumbar fusion including ≥ 1-level posterior lumbar interbody fusion (PLIF).

METHODS

The PubMed, Cochrane, and Web of Science databases were queried for all full-text English studies evaluating the use of topical TXA (tTXA), systemic TXA (sTXA), or combined tTXA+sTXA in patients undergoing PLIF. The primary endpoints of interest were operative time, IOBL, and total blood loss (TBL); secondary endpoints included venous thromboembolic complication occurrence, and allogeneic and autologous transfusion requirements. Outcomes were compared using random effects. Comparisons were made between the following treatment groups: sTXA, tTXA, and sTXA+tTXA. Given that sTXA is arguably the standard of care in the literature (i.e., the most common route of administration that to this point has been studied the most), the authors compared sTXA versus tTXA and sTXA versus sTXA+tTXA. Study heterogeneity was assessed with the I2 test, and grouped analysis using the Hedge’s g test was performed for measurement of effect size.

RESULTS

Forty-five articles were identified, of which 17 met the criteria for inclusion with an aggregate of 1008 patients. TXA regimens included sTXA only, tTXA only, and various combinations of sTXA and tTXA. There were no significant differences in operative time, TBL, or postoperative drainage between the sTXA and tTXA groups or between the sTXA and sTXA+tTXA groups.

CONCLUSIONS

The present meta-analysis suggested clinical equipoise between isolated sTXA, isolated tTXA, and combinatorial tTXA+sTXA formulations as hemostatic adjuvants/neoadjuvants in short-segment fusion including ≥ 1-level PLIF. Given the theoretically lower venous thromboembolism risk associated with tTXA, additional investigations using large cohorts comparing these two formulations within the posterior fusion population are merited. Although TXA has been shown to be effective, there are insufficient data to support topical or systemic administration as superior within the open PLIF population.

The aim of this research was to assess the hazardousness and ecotoxicity of paiche leather (Arapaima gigas) dyed with natural colourants (turmeric and purple corn) versus synthetic colourants (anilines). To determine hazardousness, the methodology included the assessment of flammability, corrosivity, reactivity to H2S and HCN, toxicity from metals, and organic compounds of dyed leather. Additionally, its ecotoxicity was determined using the California red worm (Eisenia fetida) as a bioindicator through a bioassay, with treatments at 0.02, 0.04, 0.08, 0.16, and 0.20 g of leather/g of substrate, including undyed leather and a negative control in the investigation. The hazardousness analysis results indicated that leather samples dyed with both natural and synthetic colourants are not hazardous. However, the concentrations of chromium, nickel, cadmium, and lead exceed the permitted values for their use in footwear according to the European Union. Regarding ecotoxicity, the results demonstrate that acute toxicity to E. fetida is lower for natural colourants compared to synthetic colourants, where 100% mortality occurs at concentrations between 0.04 and 0.08 g of leather/g of the substrate. Concerning chronic toxicity, after 12 weeks of exposure, the tolerance concentration for undyed paiche leather is 0.035 g of leather/g of the substrate, and for leather dyed with purple corn and turmeric, it is 0.2 g of leather/g of the substrate. It is shown that the active compounds of natural colourants have a positive effect on worm survival, and it is concluded that paiche leather dyed with these colourants presents environmental advantages over leather dyed with synthetic colourants.

Published: May 2024

AIM. Diabetes and cardiovascular diseases are among the reasons for most outpatient consultations. The study aimed to evaluate the reported experiences of patients being managed for diabetes and cardiovascular diseases in the outpatient clinics of Abuja public hospitals.

METHOD. A prospective cross-sectional study of 787 systematically sampled patients receiving care in five public hospitals in Abuja was conducted. A structured questionnaire was used to collect data on the number of yearly consultations, problems encountered in accessing trained health personnel, time spent on hospital appointments, major treatment challenges, and ways to improve their experience on hospital visits. Management experience was defined as good or poor. Patients who consulted at least four times in a year, reported no problems in accessing trained health personnel, and had no treatment challenges were regarded as having a good management experience. Frequency, percentage, mean, and standard deviation were used to summarize the data. Logistic regression was used to predict and classify the binary outcomes. A p-value ≤ 0.05 was considered significant.

RESULTS. More of the patients (66.2%) had up to four consultations in a year. Long waiting time (56.1%) was the common problem encountered when accessing trained medical personnel. The major treatment challenge was hospital waiting time (49.4%). The mean time spent in the hospital on appointment days was 5.04±1.80. Approximately 40% of the patients suggested proper scheduling of hospital appointments as the major way to improve treatment experiences. Poor management was recorded by 96.6% of the patients. Logistic regression showed that a higher educational level (OR = 0.031, 95% CI [0.008-0.119], _P=_0.001) was associated with reporting poor management.

CONCLUSION. The average number of yearly consultations was below the minimum standard, and patients spent long hours on consultation days before meeting with healthcare personnel. Most patients were dissatisfied with the services received and rated them poor.
Some Aspects of Maxwell’s Equations, Klein-Gordon Equations, and Heat and Mass Transfer Equations in an n-Dimensional Maximally Symmetric Space-Time from the Classical and Quantum Mechanical Standpoints
Authors: Parthasarathy Harish
Published: May 2024

This manuscript examines Maxwell’s equations, Klein-Gordon equations, and heat and mass transfer equations in n-dimensional maximally symmetric space-time. It investigates these equations in spherical and hyperbolic spaces embedded in higher-dimensional Euclidean and Minkowski spaces. The study focuses on the implications of these geometries and symmetries on the behaviour of the equations, highlighting how specific transformations and parametrizations impact their solutions. The findings reveal the underlying connections between geometric symmetries and physical laws, providing insights into their possible applications in theoretical physics. We touch upon both classical and quantum mechanical aspects of density and velocity evolutions with time in the universe. Quantum mechanical aspects of single and two-particle state evolution and statistical moments of the matter four-current are derived from the quantum Boltzmann equation and Feynman’s path integral method for fields applied to gravity interacting with electrons and positrons.

The Convention on the Elimination of All Forms of Discrimination Against Women (CEDAW) imposes on signatory States the obligation to implement and apply legal measures promoting equality and the elimination of gender discrimination. The General Assembly adopted it in 1979. Violence against women is, on the one hand, one of the most systematic and widespread forms of human rights violation in the world and, on the other, a socio-economic problem that impacts social harmony, economic growth and threatens overall development progress.  The consequences include the deterioration of women’s mental and physical health, disruption of communities, and a decrease in economic productivity. The manifestation of unequal power relations between women and men is one of the most extreme forms of gender-based discrimination and an attack on the dignity and fundamental rights of women and girls. Gender-based violence stems from structural causes linked to the norms and values of a society, culture, or community. These factors legitimize and perpetuate various gender inequalities based on a hierarchy of relationships between men and women, thus contributing to gender-based violence. Harmful stereotypes and traditional expectations further bolster these inequalities, restricting women's autonomy and frequently rationalizing acts of violence. At the beginning of October 2023, a woman was subjected to cruel and degrading treatment, tied up and beaten by law enforcement officers in Kisangani, the capital of Tshopo province, on the orders of her ex-husband; the latter, using his position as a public official, ordered the arrest and beating of his ex-wife by law enforcement officers; As a result, the person who gave the order and the officers who carried out the manifestly illegal order were prosecuted and convicted, in accordance with the Declaration on the Elimination of Violence against Women, which requires States to act with due diligence to prevent, investigate and punish acts of violence against women in accordance with national law, whether perpetrated by the State or by private persons. Every woman has the right to respect for the inherent dignity of the human person and to recognition and protection of her human and legal rights. This article is timely and calls for the unfailing application of provisions on respect for the recognised rights of women and girls, in the interests of a fairer and more balanced society.

IMPROVING THE CONCEPTUAL PILLARS OF EURO-INTEGRATION, FINANCIAL AND LEGAL LEVERS FOR ACCELERATION OF THE UKRAINE’S EU ACCESSION
Authors:   NGO “Growford Institute”, Bohdan Tetiana
Published: May 2024

Introduction. Since 2022, Ukraine has been following the path of “classical accession” to the EU, which involves the compliance with the Copenhagen criteria and adoption of the common EU legislation (acquis) in 33 policy areas/ chapters. But advancement withing this scenario is a long and resource-intensive process. Problem Statement. The urgent task is to find an optimal model of joining the EU with coherence to a reasonable time frame of this course, achieving high results of European integration and identification of the sources of funding for carrying out reforms and overcoming the consequences of the war after reducing the potential of the Ukraine Facility. Purpose - identification of the current financial and legal problems of the European integration process for Ukraine, generalization of the methodological pillars of the concept of staged accession to the EU as a more progressive version over the classic accession model, design of the policy proposals for updating monitoring tools and financial incentives for progressing across the subsequent stages towards the EU membership. Methods. General scientific and special methods are applied: reviews of theoretical sources, advisory and research papers, analysis of statistical data and legal documents, historical method, logical method, methods of comparison and synthesis. Results. The article summarizes the methodological pillars of the concept of staged accession to the EU, systematizes the legal mechanisms of negotiations and obtaining EU membership, shows the financial aspects of the European integration process, including access to the EU cohesion funds, and elaborates practically important proposals for the activity of the EU institutions and national bodies as to the operationalization of the model of staged accession. Conclusions. The staged accession model is the most holistic and logically structured concept that can evolve a predictable progress towards the EU membership. The model should be based on the European Commission's quantitative assessments of countries' preparedness for the membership within the framework of negotiating clusters and chapters. A system of performance indicators is also required that will record progress of the candidate countries across stages and will set the ground for disbursements from the EU funds in line with specified ratios. Since 2028, the new EU medium-term fiscal framework should provide for the formation of new funds to finance the recovery of Ukraine's economy and the application of the EU's cohesion policy towards Ukraine.
