Sleep Quality and Body Composition in Active and Inactive Young Adults
(2025) Maruszczak, Krystian; Kasperek, Wojciech; Kustra, Konrad; Przysada, Grzegorz; Kochman, Maciej
Body composition is influenced by a variety of internal and external factors, with early adulthood being a particularly sensitive period for its fluctuations. This observational study aimed to assess the differences in body composition, anthropometric indices, and sleep quality between active and inactive young adults as well as to explore the relationship between these parameters. A group of one hundred young adults were recruited for the study and assigned to two groups: physically active and physically inactive. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ-SF), sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and body composition was measured using the validated InBody 770 analyzer. Participants were classified as physically active if they achieved a "moderate" or "high" activity level according to IPAQ-SF scoring criteria, which includes individuals engaging in at least 600 MET-minutes of physical activity per week. Those categorized as physically inactive scored at the "low" level, not meeting the thresholds for moderate or high activity. Physically active individuals showed significantly more favorable body composition, including higher total body water, muscle mass, and bone mineral content, as well as lower fat mass, BMI, WHR, WHtR, and ABSI values (all p < 0.001). They also had significantly better sleep quality, as indicated by lower Global Sleep Score (GSS) scores (p<0.001). Significant associations were observed between sleep quality and body composition parameters, such as a positive correlation between the GSS and fat mass, as well as negative correlations between GSS and total body water, fat-free mass, and bone mineral content. Additionally, GSS showed positive correlations with both WHR and WHtR (p<0.05). No significant associations were found between the GSS and muscle mass, nor between GSS and ABSI (p>0.05). These findings suggest that regular physical activity is related to more favorable body composition and better sleep quality. Moreover, specific components of body composition, particularly fat mass and indicators of central adiposity, appear to be significantly associated with sleep quality, highlighting a potential link between metabolic health and sleep patterns. However, due to the cross-sectional nature of the study, causality cannot be inferred.
Important role of pregnancy planning for pregnancy outcomes in type 1 diabetes
(MDPI, 2025-06-01) Juza, Anna; Dąbrowski, Mariusz
Background/Objectives: Pregnancy in women with type 1 diabetes (T1D), compared to general pregnant population, is still associated with an increased number of perinatal complications affecting both fetus and mother. The Great Orchestra of Christmas Charity Foundation (GOCCF) program enables use of continuous subcutaneous insulin infusion (CSII) enhanced by hypo-stop function with real-time continuous glucose monitoring (rtCGM) at the stage of procreation or early pregnancy in T1D patients. The aim of this observational study was to analyze association between pregnancy planning and pregnancy outcomes in patients qualified for the GOCCF program. Methods: 98 women with T1D, aged 21-41 years, initiating CSII + rtCGM system at the stage of planning/early pregnancy or later in case of unplanned pregnancy were quali-fied for the study. We analyzed glycemic control, insulin requirements, pregestational BMI, maternal weight gain, occurrence of preterm birth, congenital malformations and birthweight of newborns. Results: Women who planned pregnancy had significantly better glycemic control before and throughout entire pregnancy and significantly higher proportion of them achieved TIR >70% (58.7% vs. 28.9%, P=0.014) and TAR <25% (65.2% vs. 24.4%, P<0.001). Their glucose variability at the end of pregnancy was significantly lower, 29.4±5.5, vs. 31.9±5.1, P=0.030. They also gave birth later, after mean 37.8±0.9 vs. 36.9±1.8 weeks in non-planning group, P=0.039. Preterm birth oc-curred in 5 women (10,4%) who planned pregnancy and in 15 women (30%) with un-planned gestation, P=0.031. Conclusions: Planning pregnancy in T1D is associated with better glycemic control before conception and throughout entire pregnancy, which is translated into better pregnancy outcomes.
The citizen science and ethnomycology of Aureoboletus projectellus – is a new invasive mushroom species being adopted and spread by mycophilous fungi gatherers in Poland?
(2025) Pietras, Marcin; Robak, Dominika; Terlecka, Magdalena; Łuczaj, Łukasz
Aureoboletus projectellus is an American Boletaceae mushroom species that appeared on the shores of the Baltic Sea at the end of the 20th century. The mushroom was soon gathered by local communities, and fungi enthusiasts travelled from all over Poland to gather this new food item. The aim of our study was to investigate the spread of the invasive Aureoboletus projectellus and its use in mycophylic Poland through an interview-based ethnomycological survey (carried out in the field and online). We gathered 274 questionnaires, and recorded many new localities of the species inland, all over the country, far from the original sites of invasion along the Baltic Sea. We have not found any clear correlation between the origin of the collectors coming to hunt it by the Baltic Sea and its localities inland.
Dataset used in research paper entitled "Evaluation of anticancer activity of urotropine surface modified iron oxide nanoparticles using a panel of forty breast cancer cell lines "
(Taylor & Francis, 2025-02-28) Adamczyk-Grochala, Jagoda; Wnuk, Maciej; Oklejewicz, Bernadetta; Klimczak, Katarzyna; Błoniarz, Dominika; Deręgowska, Anna; Rzeszutek, Iwona; Stec, Paulina; Ciuraszkiewicz, Agnieszka; Kądziołka-Gaweł, Mariola; Łukowiec, Dariusz; Piotrowski, Piotr; Litwinienko, Grzegorz; Radoń, Adrian; Lewińska, Anna
Urotropine, an antibacterial agent to treat urinary tract bacterial infections, can be also considered as a repurposed drug with formaldehyde-mediated anticancer activity. Recently, we have synthesized urotropine surface modified iron oxide nanoparticles (URO@Fe3O4 NPs) with improved colloidal stability and limited cytotoxicity against human fibroblasts. In the present study, we have investigated URO@Fe3O4 NP-mediated responses in a panel of forty phenotypically different breast cancer cell lines along with three non-cancerous corresponding cell lines. URO@Fe3O4 NPs promoted oxidative stress and FOXO3a-based antioxidant response in breast cancer cells. Elevated levels of GPX4 and decreased levels of ACSL4 in URO@Fe3O4 NP-treated breast cancer cells protected against ferroptotic cell death. On the contrary, URO@Fe3O4 NPs impaired the activity of PERK, a part of unfolded protein response (UPR), especially when the glucose supply was limited, that was accompanied by genetic instability, and apoptotic and/or necrotic cell death in breast cancer cells. In conclusion, this is the first comprehensive analysis of anticancer effects of URO@Fe3O4 NPs against a panel of forty breast cancer cell lines with different receptor status and in glucose replete and deplete conditions. We suggest that presented results might be helpful for designing new nano-based anti-breast cancer strategies.
Changes taking place in the media image of an academic organization. Study on the example of students' opinions.
(2025-03-24) Garwol, Katarzyna
At the intersection of media studies, sociology of education and public relations, the concept of the image of an academic organization is situated. Contemporary the media image of university is the result of interaction with institutional messages conducted often in social media and through various digital platforms. The theory of the university image is a developed research field, however, recent changes in media and educational landscape, due to the Covid-19 epidemic, resulted with a research gap. This paper describes an empirical research conducted by the authors, that is dedicated to uncover changes in the perception of the image of the university and the faculty/college from the student's perspective after long period of hybrid and online studies. The subject was narrowed down to the media image of academic organization created through websites and social media. The state of art part of the paper proves why attention should be paid to the ubiquity of digitization in academic education and the intensifying digitalisation of communication. CAWI research conducted at selected public universities in Poland (University of Warsaw and University of Rzeszów). The collected and recent material allows to identify aspects of university image related to organizational communication.
