Update on the association between Helicobacter pylori infection and asthma in terms of microbiota and immunity
Authors: Liu Mengmeng , Wang Yong , Du Bing
Published: January 2024

H. pylori is a gram-negative bacterium that is usually acquired in childhood and can persistently colonize the gastric mucosa of humans, affecting approximately half of the world’s population. In recent years, the prevalence of H. pylori infection has steadily reduced while the risk of allergic diseases has steadily climbed. As a result, epidemiological research indicates a strong negative association between the two. Moreover, numerous experimental studies have demonstrated that eradicating H. pylori increases the risk of allergic diseases. Hence, it is hypothesized that H. pylori infection may act as a safeguard against allergic diseases. The hygiene hypothesis, alterations in gut microbiota, the development of tolerogenic dendritic cells, and helper T cells could all be involved in H. pylori’s ability to protect against asthma. Furthermore, Studies on mice models have indicated that H. pylori and its extracts are crucial in the management of asthma. We reviewed the in-depth studies on the most recent developments in the relationship between H. pylori infection and allergic diseases, and we discussed potential mechanisms of the infection’s protective effect on asthma in terms of microbiota and immunity. We also investigated the prospect of the application of H. pylori and its related components in asthma, so as to provide a new perspective for the prevention or treatment of allergic diseases.

Authors: Sharma Varun , Ricketts Helen Clare , Steffensen Femke , Goodfellow Anna , Buchan Duncan S , Cowan Douglas C
Published: January 2024

Introduction

Poor sleep health is associated with increased asthma morbidity and mortality. Accelerometers have been validated to assess sleep parameters though studies using this method in patients with asthma are sparse and none have compared mild to difficult-to-treat asthma populations.

Methods

We performed a retrospective analysis from two recent in-house trials comparing sleep metrics between patients with mild and difficult-to-treat asthma. Participants wore accelerometers for 24-hours/day for seven days.

Results

Of 124 participants (44 mild, 80 difficult-to-treat), no between-group differences were observed in sleep-window, sleep-time, sleep efficiency or wake time. Sleep-onset time was ~ 40 min later in the difficult-to-treat group (p = 0.019).

Discussion

Broadly, we observed no difference in accelerometer-derived sleep-metrics between mild and difficult-to-treat asthma. This is the largest analysis of accelerometer-derived sleep parameters in asthma and the first comparing groups by asthma severity. Sleep-onset initiation may be delayed in difficult-to-treat asthma but a dedicated study is needed to confirm.
Subcutaneous dirofilariasis in a 25-year-old male patient in Belgium on ultrasonography: a case report
Authors: Klerkx Scott , Venstermans Caroline
Published: January 2024

Background

Subcutaneous dirofilariasis is a parasitic zoonosis commonly described in Canidae but rarely seen in humans. Most physicians are unfamiliar with this disease, especially in nonendemic areas, which can lead to medication error and diagnostic and treatment delay. To the best of our knowledge, no previous case of subcutaneous dirofilariasis preoperatively diagnosed on ultrasound has been described in Western Europe.

Case presentation

A 25-year-old Belgian male patient presented with a subcutaneous nodule in the epigastric region. Ultrasound investigation showed a typical cystic lesion with an internal serpiginous structure with echogenic lines, and there was active twirling movement of this serpentine structure during investigation, pathognomonic for subcutaneous dirofilariasis. Surgical extirpation was performed, and the diagnosis was histopathologically confirmed.

Conclusion

Subcutaneous dirofilariasis has a characteristic appearance on ultrasound but is not well known in nonendemic areas, often leading to diagnostic delay and initial incorrect treatment. More knowledge of this disease and of its characteristic ultrasound appearance will hopefully lead to better patient care.
Synergistic integration of Multi-View Brain Networks and advanced machine learning techniques for auditory disorders diagnostics
Authors: Ahmed Muhammad Atta Othman , Satar Yasser Abdel , Darwish Eed M. , Zanaty Elnomery A.
Published: January 2024

In the field of audiology, achieving accurate discrimination of auditory impairments remains a formidable challenge. Conditions such as deafness and tinnitus exert a substantial impact on patients’ overall quality of life, emphasizing the urgent need for precise and efficient classification methods. This study introduces an innovative approach, utilizing Multi-View Brain Network data acquired from three distinct cohorts: 51 deaf patients, 54 with tinnitus, and 42 normal controls. Electroencephalogram (EEG) recording data were meticulously collected, focusing on 70 electrodes attached to an end-to-end key with 10 regions of interest (ROI). This data is synergistically integrated with machine learning algorithms. To tackle the inherently high-dimensional nature of brain connectivity data, principal component analysis (PCA) is employed for feature reduction, enhancing interpretability. The proposed approach undergoes evaluation using ensemble learning techniques, including Random Forest, Extra Trees, Gradient Boosting, and CatBoost. The performance of the proposed models is scrutinized across a comprehensive set of metrics, encompassing cross-validation accuracy (CVA), precision, recall, F1-score, Kappa, and Matthews correlation coefficient (MCC). The proposed models demonstrate statistical significance and effectively diagnose auditory disorders, contributing to early detection and personalized treatment, thereby enhancing patient outcomes and quality of life. Notably, they exhibit reliability and robustness, characterized by high Kappa and MCC values. This research represents a significant advancement in the intersection of audiology, neuroimaging, and machine learning, with transformative implications for clinical practice and care.

Published: January 2024

Background

Several systematic reviews (SRs), with and without meta-analyses, have investigated the use of wearable devices to improve physical activity, and there is a need for frequent and updated syntheses on the topic.

Objective

We aimed to evaluate whether using wearable devices increased physical activity and reduced sedentary behaviour in adults.

Methods

We conducted an umbrella review searching PubMed, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, MedRxiv, Rxiv and bioRxiv databases up to February 5th, 2023. We included all SRs that evaluated the efficacy of interventions when wearable devices were used to measure physical activity in adults aged over 18 years. The primary outcomes were physical activity and sedentary behaviour measured as the number of steps per day, minutes of moderate to vigorous physical activity (MVPA) per week, and minutes of sedentary behaviour (SB) per day. We assessed the methodological quality of each SR using the Assessment of Multiple Systematic Reviews, version 2 (AMSTAR 2) and the certainty of evidence of each outcome measure using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations). We interpreted the results using a decision-making framework examining the clinical relevance and the concordances or discordances of the SR effect size.

Results

Fifty-one SRs were included, of which 38 included meta-analyses (302 unique primary studies). Of the included SRs, 72.5% were rated as ‘critically low methodological quality’. Overall, with a slight overlap of primary studies (corrected cover area: 3.87% for steps per day, 3.12% for MVPA, 4.06% for SB) and low-to-moderate certainty of the evidence, the use of WDs may increase PA by a median of 1,312.23 (IQR 627–1854) steps per day and 57.8 (IQR 37.7 to 107.3) minutes per week of MVPA. Uncertainty is present for PA in pathologies and older adults subgroups and for SB in mixed and older adults subgroups (large confidence intervals).

Conclusions

Our findings suggest that the use of WDs may increase physical activity in middle-aged adults. Further studies are needed to investigate the effects of using WDs on specific subgroups (such as pathologies and older adults) in different follow-up lengths, and the role of other intervention components.
Determinants of conventional and digital investment advisory decisions: a systematic literature review
Authors: Wagner Fabian
Published: January 2024

The growing demand for digital investment advisory services and the advancing technological process led to increased attention to this topic in recent literature. In light of these developments, the question arises whether conventional and digital advisors behave differently in their investment advisory decisions. I therefore conducted a systematic literature review and evaluated 97 publications on the determinants of conventional and digital investment advisory decisions. Based on the literature, five main determinants were identified that are important for investment advisory decisions. These determinants are identical for both variants of the advice, but there are differences in the way they are addressed. This systematic literature review provides an overview of the current state of research and can therefore help identify areas where investment advice can be improved in the future.
How do supply or demand shocks affect the US oil market?
Authors: Vides José Carlos , Feria Julia , Golpe Antonio A. , Martín-Álvarez Juan Manuel
Published: January 2024

The study of the relationship between crude oil and its refined products prices may be perceived as an important tool for testing how are the dynamics and the type of integration of the petro-derivatives market in the United States. In this sense, we have applied a set of causality tests to study the possible presence of asymmetries in the relationship between WTI crude oil and each refined product price and to explore the type of market integration. Furthermore, the application of these causality tests lets us explore the validation of different hypotheses in the literature, such as the Rocket and Feathers hypothesis and the Verleger hypothesis. Our findings reveal that Reformulated Gasoline Blendstock for Oxygen Blending (RBOB), heating oil, diesel and kerosene are supply-driven integrated and conventional gasoline and kerosene are demand-driven integrated when linear effects are assessed. This behaviour changes deeply when the existence of asymmetries is tested, noticing that the Rocket and Feathers hypothesis is not fulfilled when a negative shock appears. Conversely, the Verleger hypothesis is supported when a negative shock appears for conventional gasoline and kerosene. These results provide important policy implications for investors, energy policymakers and refiners.

Formation of the foundations of ecological and patriotic culture of younger schoolchildren in extracurricular activities
Authors: Morozova E. , Skidanova K.
Published: January 2024

The purpose of the article is to evaluate the effectiveness of the extracurricular activity program "Eco-friend of our school" for the formation of the foundations of the ecological and patriotic culture of younger schoolchildren. The article presents the experience of introducing the program into the extracurricular activities of younger schoolchildren (organized on the basis of the innovative regional educational platform of the «Secondary School No. 60» named after Hero of the Soviet Union P.F. Batavin in the 2022-2023 academic year) during the solution of project tasks: "We decided to build a house", "Festival of Children's Ecological Theaters", "School of Good Deeds", "Portrait of the hometown". The article substantiates the need to focus on the development of the patriotic component in the structure of the ecological and patriotic culture of the representatives of the younger generation. A significant basis of the work is the modeling of the image of the house, school, city and small homeland with the orientation of the younger student to the image of a patriot with his inherent qualities (the desire to perform socially significant functions in the family, school community, in various spheres of society, to protect nature, high spirituality). The semantic field of the concept of "ecological and patriotic culture" is analyzed. It is revealed that the proposed program of extracurricular activities can be considered effective due to qualitative changes in the personality of a younger student as a result of complex diagnostics ("AESOP" V.A. Yasvina, D.V. Grigoriev's method of diagnostics of personal growth, the method "Who am I?" (modification of M. Kuhn's method)), the study of the art of younger schoolchildren).

Authors: Tolmacheva E. , Machy L.
Published: January 2024

The authors consider the problem of hemispheric asymmetry and its impact on the results of language acquisition. The age and type of nervous system are given as the main criteria determining the degree of manifestation of hemispheric asymmetry. Theoretical data on the importance of the work of the left and right hemispheres from the linguistic point of view are stated, as well as arguments in favor of using exercises aimed at involving both hemispheres in the learning process. The authors rely on theoretical works in order to identify age-related functional changes in the work of the hemispheres, partially correlate these changes with the stages of development of thinking. The results of experiments conducted with two groups of respondents belonging to different categories are analyzed. The first group of respondents are students studying Russian as a foreign language. The second group is English-Russian bilinguals. In order to eliminate errors related to gender and age, the sample was carried out according to the following principle: group 1 - a girl and a boy (18 years old), group 2 - a girl and a boy (17.5 years old). The results of girls and boys are compared separately based on data on the sex differences of the brain. The neuropsychological and linguistic methods used for the ascertaining experiment and the features of their use for testing each group of respondents are described.

The article presents the results of a formative experiment conducted over two months, for which individual exercise systems were developed aimed at forming interhemispheric interaction between bilinguals and foreign students studying Russian.

Based on the comparison of the obtained data, conclusions are drawn, as well as a theoretical justification of the experimental results is given.

The effectiveness of pedagogical means in the development of preschooler giftedness
Authors: Nelipa N. , Gudim V. , Kurmaz T.
Published: January 2024

The harmony of the child's personality is possible only with the simultaneous development of the intellectual and emotional spheres of his psyche. Age patterns and individual differences between children of the same age pose complex tasks for the teacher-musician and educators. Individual indicators of individual children significantly exceed the average age. Here you can talk about the giftedness of the child. One of the effective conditions for the development of preschool children today is the organization of a system of additional education in a preschool educational institution, which can ensure the transition from the interests of children to the development of their abilities. Another important aspect that is carried out in parallel with the implementation of the DOOP is work with parents. We must help parents to learn how to treat the abilities and capabilities of their children correctly, so that they become helpers for them, and not hinder their development. With the right work with parents, they come to the level of creative cooperation with the teacher and the child and very successful adult-child projects arise.

Neuropsychological correction in additional education is an effective means of working with children with disabilities
Authors: Esupova R.
Published: January 2024

The article presents the author's view on the application of neuropsychological correction in additional education. In recent decades, a lot of children have demonstrated delays and distortions of psychorechological development, lack of formation of arbitrary self-regulation, dysgraphy, etc. Together, this leads to emotional, personal and cognitive unpreparedness for learning and adequate adaptation to society. The priority participation of neuropsychology —the science of the formation of the brain organization of human mental processes in solving a wide range of dysontogenetic problems is primarily due to the depressing realities of development processes in the modern child population. Never before have we encountered such an abundance of negative phenomena as are observed today. Neuropsychological analysis of the problems of deviant development, which has been actively developing in our country since the early 1980s, immediately proved to be the most reliable and productive. This is natural, since it is based on a powerful methodological and scientific-practical base developed in general neuropsychology, neuropsychology of childhood, the theory of neuropsychological rehabilitation.

Published: January 2024

Background and Aim: Schools are ideal settings for interventions against diseases to develop sustainable and healthy behaviors that improve long-term health outcomes. The water, sanitation, and hygiene (WASH) in Schools (WinS) program provides school-based interventions to address health concerns. The integration and practice of the One Health approach in schools may provide useful synergies for improved WinS program efficiency by harmonizing the multisectoral efforts of various stakeholders involved; therefore, this study aimed to revisit the WinS program using the One Health Lens.

Materials and Methods: Qualitative methods employed included key informant interviews and focus groups to describe the status of WinS implementation in relation to community WASH and other health programs in the selected study sites using the One Health lens.

Results: Good practices in WinS implementation, including public-private sector partnerships to finance construction of WinS facilities, recognition of outstanding schools and innovations to improve program measures, and intensified health education through multimedia channels, were identified. Challenges include deworming hesitancy, disruption of services due to pandemics and disasters, difficulties in sustainable financing of facilities and supplies, inclusive infrastructure, reaching Last Mile schools in Geographically Isolated, Disadvantaged, and Conflict Areas, and the need to connect WinS, community WASH, and other health programs.

Conclusion: WASH has proven to be a viable vehicle for improving the health of people in schools and community settings. The study showed that health concerns require a concerted effort of public and private authorities. This study elicited the need to bridge the WASH program implemented in schools with community-based programs to ensure that policies are responsive and that logistic support is provided sustainably. Implementing the Universal Health Care Act and developing and using existing mechanisms for coordination between sectors, such as Healthy Learning Institutions, provide opportunities for aligning programs with the government health agenda.

Published: January 2024

Background and Aim: Houseflies (Musca domestica) are synanthropic insects that are vectors of a wide range of multidrug-resistant pathogens responsible for infectious diseases. The aim of this study was to detect and characterize multidrug-resistant Enterobacteriaceae carried by houseflies in Bobo-Dioulasso.

Materials and Methods: A total of 500 houseflies were captured in hospital and non-hospital environments in the city of Bobo-Dioulasso. For bacteriological analysis, they were divided into 125 batches of five flies each. Multidrug-resistant bacteria isolated on MacConkey agar supplemented with 4 μg/mL cefotaxime were identified on the basis of biochemical characteristics. Antibiotic susceptibility profiles were determined using the agar diffusion method. blaCTX-M resistance genes and quinolone resistance genes (plasmid-mediated quinolone resistance) were detected by conventional polymerase chain reaction.

Results: Among 115 bacterial strains obtained, 26 were extended-spectrum beta-lactamase (ESBL)-producing enterobacteria: Escherichia coli (15), Klebsiella pneumoniae (6), Enterobacter cloacae (4), and Morganella morganii (1). Carriers were statistically more important in hospitals (12/26, p = 0.03). No carbapenem-resistance strains were observed. We identified ESBL resistance genes (Cefotaximase Munich; CTX-M group 1) (25/26) and quinolone resistance genes (QnrS) (6/26).

Conclusion: Houseflies in the city of Bobo-Dioulasso are vectors for the transmission of multidrug-resistant enterobacteria. There is a need to monitor the associated risks for public health.

Keywords: Bobo-Dioulasso, extended-spectrum beta-lactamase, Gram-negative bacilli, housefly, multiresistant Enterobacteriaceae.

Authors: Nishimoto Taiki , Takagi Kyoka , Aoki Dan , Fukushima Kazuhiko , Matsushita Yasuyuki
Published: January 2024

A lignin model oligomer with only β-O-4 linkages and a selectively deuterium-labelled methoxy group at the phenolic terminal units was synthesised to clarify the behaviour of the phenolic end of oligolignols. First, t-butoxycarbonylmethyl vanillin was synthesised and oligomerised by nucleophilic addition, a known method. The terminal of the oligomers was then subjected to nucleophilic addition to [3-OCD3]benzyl vanillin to achieve selective labelling of the terminal units. A deuterium-labelled lignin model oligomer (D-LM) was obtained through debenzylation and subsequent reduction. The results of thioacidolysis after methylation revealed that the degree of polymerisation was about five, and the deuterium-labelled phenylpropane unit was located only at the phenolic terminal moiety.

Ctenomys paramilloensis Roig et al. (1975. Ctenomys paramilloensis, una nueva especie de tucu-tuco de la Sierra de Uspallata, provincia de Mendoza (Rodentia, Octodontidae). In: Resúmenes IV Jornada Argentina de Zoología. Corrientes, Argentina), was coined to represent populations for this caviomorph (Hystricomorpha) subterranean rodent inhabiting a high Andean isolated tableland in the Sierra de Uspallata, Mendoza, Argentina. To evaluate the validity of this nominal form we conducted a field sampling involving several localities within the target geographical area. The results obtained indicate that all the sampled populations belong to the widespread Ctenomys mendocinus Philippi, 1869. Accordingly, C. paramilloensis is resolved as a junior synonym of the latter.

Objectives

Integrin subunit beta-like 1 (ITGBL1), a member of the epidermal growth factor (EGF)-like protein family, encodes a beta integrin-related protein that is mainly associated with the development of specific tumours and immune-related signalling pathways. This work aimed to explore the possibility that ITGBL1 functions as a novel target gene for immunotherapy and could be a cancer prognostic molecule.

Methods

The mRNA data for ITGBL1 were obtained from the public databases The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx) and Gene Expression Omnibus (GEO). Using GEPIA, the differential expression of ITGBL1 in different tumour stages was identified. Cancer prognostic correlations were explored using Kaplan–Meier survival analysis and forest plots. A combination of Gene Set Enrichment Analysis (GSEA), TIMER2.0 and the R package was applied to analyse the ITGBL1-enriched related pathways. The NCI-60 drug database was examined using CellMinerTM. Cytological experiments were conducted to confirm ITGBL1’s impact on cancer cells.

Results

Our research has shown that ITGBL1 is differentially expressed in 26 cancers, and high ITGBL1 expression predicts a poorer survival prognosis in some specific cancers. Additionally, we found that ITGBL1 is enriched in immune-related pathways, which are closely linked to immunomodulatory molecules, immune-infiltrating cells, and immunomodulatory factors. The results of tumor mutational burden (TMB) and microsatellite instability (MSI) also indicate that the expression of ITGBL1 is beneficial for improving tumor immunotherapy efficacy. Furthermore, a number of antitumor agents associated with ITGBL1 expression have been identified. Finally, knockdown of ITGBL1 restricts the ability of gastric and colorectal cancer cells to proliferate and migrate.

Conclusions

Our study demonstrates that ITGBL1 can be utilized to accurately prognosticate cancer and has opened up new avenues for the investigation of tumor immune mechanisms and the development of more efficacious immunotherapies.

Published: January 2024

In this paper, in order to study the effect of emulsification on the oil displacement of the system, several polymer, surfactant/polymer (S/P) and alkali/surfactant/polymer (A/S/P) systems were prepared for experiments. Firstly, the interfacial tension of each system was investigated. After the emulsion was prepared, the droplet size was observed by microscope and the intensity of the backscattered light during the destabilisation process of the emulsion was tested with the stability analyser. The TSI value was calculated to evaluate the stability of the emulsion. Finally, the Berea core displacement experiment (chemicals are used to displace oil from the core) was carried out to test the ability to enhance the oil recovery. The experimental results show that the emulsion formed by the A/S/P system with the simulation oil has the best stability. The chemical displacement recovery is the highest, which is 32.15 %. The emulsion stability of the S/P system is second, and the chemical displacement recoveries are 17.03 % and 20.76 %, respectively. The polymer system has no interfacial activity, does not form an emulsion, and has the lowest chemical displacement recovery of 8.02 %. This shows that the deeper the degree of emulsification of the system and the more stable the emulsion, the better the oil displacement effect of the oil displacement system.

Ben Othman, A, Anvar, SH, Aragão-Santos, JC, Behm, DG, and Chaouachi, A. Relative cross-education training effects of male youth exceed male adults. J Strength Cond Res XX(X): 000–000, 2024—Cross-education has been studied extensively with adults, examining the training effects on contralateral homologous muscles. There is less information on the cross-education effects on contralateral heterologous muscles and scant information comparing these responses between adults and youth. The objective was to compare cross-education training effects in male youth and adults to contralateral homologous and heterologous muscles. Forty-two male children (10–13-years) and 42 adults (18–21-years) were tested before and following an 8-week unilateral, dominant or nondominant arm, chest press (CP) training program or control group (14 subjects each). Unilateral testing assessed dominant and nondominant limb strength with leg press and CP 1 repetition maximum (1RM), knee extensors, elbow extensors (EE), elbow flexors, and handgrip maximum voluntary isometric contraction (MVIC) strength and shot put distance and countermovement jump height. Upper-body tests demonstrated large magnitude increases, with children overall exceeding adults (p = 0.05—p < 0.0001, η
2: 0.51, 10.4 ± 11.1%). The dominant trained limb showed significantly higher training adaptations than the nondominant limb for the adults with CP 1RM (p = 0.03, η
2: 0.26, 6.7 ± 11.5%) and EE (p = 0.008, η
2: 0.27, 8.8 ± 10.3%) MVIC force. Unilateral CP training induced significantly greater training adaptations with the ipsilateral vs. contralateral limb (p = 0.008, η
2: 0.93, 27.8 ± 12.7%). In conclusion, children demonstrated greater training adaptations than adults, upper-body strength increased with no significant lower-body improvements, and ipsilateral training effects were greater than contralateral training in adults.
Poland’s institutional cycles. Remarks on the historical roots of the contemporary institutional matrix
Authors: Pieczewski Andrzej
Published: January 2024

The aim of this article is to identify and evaluate institutional cycles (periods with a permanent predominance of dominant institutions that determine the entire political–economic system) in Poland’s history and assess them in terms of the predominance of inclusive or extractive political and economic institutions. The Polish lands lying at the edge of Western civilisation were in the orbit of the influence of both West and East. It adopted institutions from both sides while creating its own, original organisations. Ultimately, Western institutions prevailed. However, over the course of Poland’s more than 1,000-year history, extractive institutions predominated, making the country backward in relation to the West. The article applies theory derived from new institutional economics and historical analysis to explore Poland’s institutional cycles.
Belarus – institutional cycles and the historical roots of the contemporary institutional matrix
Authors: Sidarava Aliaksandra
Published: January 2024

One modern area of academic research involves searching prerequisites for the formation and functioning of specific institutional models within countries. The purpose of the article is to identify and analyze the main institutional cycles in the formation of the socioeconomic systems of Belarus. This will help determine the effect of historical dependence on the trajectory of development and allow the identification of the origins of the country's modern institutional matrix. The novelty of the study of institutional cycles and their dynamics lies in its interdisciplinary nature. The author has adopted the theory within New Institutional Economics, particularly the achievements of North, Acemoglu, and Robinson. The research methods include a historical analysis and a comparative analysis.
Spław wiślany w 1662 roku (w świetle rejestru celnego komory nowodworskiej)
Authors: Kazusek Szymon
Published: January 2024

W artykule omówiony został spław wiślany w 1662 r. na podstawie jedynego zachowanego rejestru komory celnej na Wiśle z drugiej połowy XVII w. Przedstawiona analiza sezonowości żeglugi wiślanej dowiodła, że znany z literatury spław z tzw. pierwszą wodą nie odgrywał kluczowej roli w handlu. Zależał on istotnie od pory letnich i jesiennych deszczów w żegludze z nurtem rzeki, a także od rytmu potrzeb konsumenckich. Dowiedziono zależności pomiędzy wielkością transportu wodnego a kategorią społeczną uczestnika spławu oraz porą sezonu żeglugowego. Wykazano dominujący udział szlachty w spławie z nurtem Wisły oraz mieszczan w spławie w górę rzeki. Opisano strukturę taboru wodnego, a także preferencje w zakresie jego wykorzystania, w tym także w zależności od pory roku kalendarzowego. Przedstawiono strukturę własności jednostek pływających, zwracając uwagę na dominację szlachty. Podkreślono rolę Warszawy i innych, w tym nadwiślańskich, miast w handlu spławnym. Scharakteryzowano pełną strukturę spławianych towarów, a także środowisko uczestników spławu, dostrzeżono rolę dopływów Wisły w handlu spławnym. Porównując badane zjawisko ze spławem w latach 1605–1651 oraz w 1766 r., dowiedziono wyjątkowego znaczenia handlu wiślanego tuż po potopie szwedzkim.
