Evidence-based intrapartum supportive care in Turkiye: A randomized controlled trial
(BioMed Central Ltd, 2026) Çevik, Esra; Yanıkkerem, Emre
Background The integration of evidence-based supportive care practices into intrapartum care is increasingly
emphasized in international guidelines, as such practices are considered fundamental to ensuring safe, respectful, and
woman-centered maternity services. Despite growing awareness, supportive practices remain under-implemented
in clinical settings. Therefore, this study aimed at investigating the effect of supportive care provided in line with
evidence-based practices during the intrapartum period.
Methods The study has a randomized controlled intervention design, in which participants were randomly allocated
to the intervention or control group. This study was conducted in a public hospital, a province in Balıkesir, Türkiye. The
study sample comprised (n=104) pregnant women assigned to the intervention (n=52) and control (n=52) groups.
Participants were matched for age, education level, body mass index, the number of births and pregnancies, and
participation in prenatal preparation classes. During the intrapartum period, the participants in the intervention and
control groups were given supportive care and routine care, respectively. The Descriptive Characteristics of Women
Questionnaire, State Anxiety Inventory (SAI), Visual Analogue Scale (VAS), pain diagram, and labor and postpartum
evaluation form were used to collect the data. Data were analyzed using SPSS version 26.0. Group comparisons
were performed using chi-square and Fisher’s exact test for categorical variables and Student’s t-test for continuous
variables showing a normal distribution. Intra-group comparisons were performed using paired t-tests, and repeated
measures were analyzed using analysis of variance with Bonferroni post hoc correction. Effect sizes were calculated
using Cohen’s d. In the analysis of the data, Student’s t-test, paired t-test, repeated measures of ANOVA (post hoc:
Bonferroni) and Cohen’s d were used.
Results The participants in the intervention group tended to have lower mean VAS and SAI in the latent, active
and transition phases after they received supportive care. The duration of labor was shorter with the intervention
compared to the control group (9.2±5.4 h vs. 12.6±6.8 h, p=.005). The perceived difficulty of labor was also lower
with the intervetion (7.8±2.0 vs. 9.4±1.2, p<.001). Maternal satisfaction scores were higher with the intervention
compared to the control group (9.9±0.2 vs. 7.2±1.6, p<.001).
Conclusion The research found that pregnant women who received supportive care during labor, tended to have
lower perceived labor pain and state anxiety levels, shorter labor duration, and lower perceived difficulty during
labor compared to those who received standard care. Additionally, the postpartum maternal satisfaction scores
tended to be higher in the intervention group. Future research should focus on longitudinal studies evaluating the
effects of supportive care provided during the intrapartum period on the postpartum well-being of mothers and the
breastfeeding process.

Analyzing urban growth dynamics for gebze: Geographic information systems and ai-based parameter optimization
(Konya Teknik Univ, 2026) Altıner, Figen; Yapışkan, Dilara
This study aims to investigate the effect of population parameters on changes in urban
land cover/use in the Gebze district for the years 2010, 2015, and 2024 through spatial analyses and a
fractional-order mathematical model. The fractional-order mathematical model is applied to examine the
dynamics of urban growth in the district, while model parameters are optimized via an artificial
intelligence–based approach. Additionally, the potential urban growth scenarios for Gebze were
simulated by MATLAB to project population growth for 2038. Subsequently, changes in land use for the
specified years are calculated using Remote Sensing and Geographic Information Systems. In light of the
results obtained, industrialisation, among the economic indicators, emerges as a key factor influencing
urban population growth and land use change in the Gebze district. The expansion of industrial areas by
95.2% between 2010 and 2024 has driven a 41.2% increase in urban growth, while projections for 2038
estimate that the population of Gebze district will range between 600.000 and over 2.000.000. While the
increase in population due to industrial development in the district by 2038 is expected to bring
economic benefits, it may also lead to certain ecological and socio-cultural issues.
Effects of dietary salt and boric acid on milk quality in savak akkaraman sheep
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Beyazgül, Pelin; Akarsu, Selçukhan; Baykalır, Yasin; Şimşek, Ülkü Gülcihan
This study evaluated the effects of varying dietary salt and boric acid addition doses on the milk quality of Savak Akkaraman sheep. A total of 120 animals were as-signed to six treatment groups (n = 20): control (C), rock salt (S; 10 g/day), boric acid 20 mg/day (B20), boric acid 40 mg/day (B40), BS20 (20 mg boric acid + 10 g/day rock salt), and BS40 (40 mg boric acid + 10 g/day rock salt). All analyses were performed in duplicate on six samples, taken on days 30 and 35 following the administration of the additives. Physicochemical analyses only showed significant variation in milk pH (p = 0.006), while acidity, dry matter, and ash remained unaffected. Strong positive correlations were found among protein, lactose, salt, and density (r > 0.95; p < 0.001). Coagulation times differed widely, with the longest being observed in BS20 (995.03 s) and the shortest in BS40 (141.73 s). Among mineral parameters, only selenium levels differed significantly between the treatment groups (p < 0.05). No significant differences were found for fat, solids-not-fat, lactose, freezing point, or electrical conductivity. Importantly, boron addition had a significant influence on total casein content (p < 0.001). Overall, dietary rock salt and boric acid did not markedly alter the basic milk composition but produced notable physicochemical changes, particularly in coagulation behavior and casein levels, which may influence the technological properties of sheep milk. © 2026 by the authors.
The relationship between organizational agility and individual work performance in nurse managers: The mediator role of person-organization fit
(John Wiley and Sons Inc, 2026) Öz, Seda Değirmenci; Karadaş, Ayşe; Gülşen, Mehmet; Çağlar, Serpil Subaşı
Aim: This study was planned with a multi‐centre design to investigate the mediator role of person‐organization fit in therelationship between organizational agility and individual work performance in nurse managers.Method: This multi‐centre, descriptive cross‐sectional study was carried out with 169 nurse managers working at four publichospitals and two university hospitals operating in two provincial centres. Data were collected face‐to‐face between January 2025and March 2025 using a ‘Personal Information Form,’ the ‘Person‐Organization Fit Scale,’ the ‘Individual Work PerformanceQuestionnaire,’ and the ‘Organizational Agility Scale.’ Data were analysed using the SPSS Statistics 30.0 programme and thePROCESS Macro v4.2 extension with frequency, percentage, mean and standard deviation values, t‐tests, Kruskal–Wallis tests andPearson's correlation analyses.Results: Organizational agility had a significant and positive effect on person‐organization fit (B = 0.811, SE = 0.068, p < 0.05).Person‐organization fit significantly predicted individual work performance (B = 0.190, SE = 0.062, p < 0.05). The indirect effectof organizational agility on individual work performance was also significant (B = 0.154, SE = 0.049, 95% CI: 0.053–0.246).Therefore, person‐organization fit mediated the relationship between organizational agility and individual work performance.Conclusion: This study demonstrated the mediator role of person‐organization fit in the relationship between organizationalagility and individual work performance in nurse managers. The results of the study showed that an increase in organizationalagility indirectly and positively affected individual work performance via the mediation of person‐organization fit.
Migration of phthalates, bisphenols, photoinitiators, and perfluorinatedcompounds in polyethylene and polystyrene based beverage cups
(Taylor & Francis Inc., 2026) Kıralan, Sezer; Toptancı, İsra; Sezer, Cansu
Disposable paper cups are widely used for consuming beverages, particularly hot drinks, in daily life.However, concerns regarding the migration of hazardous chemicals from these cups into beverageshave been largely overlooked. This study investigates the presence of phthalates, bisphenols,photoinitiators (PIs), and two perfluorinated compounds (PFC) in polyethylene and polystyrenebased beverage cups from Turkey. Potential migrants were quantified using liquid chromatography–tandem mass spectrometry (LC–MS/MS) in a total of 40 cup samples. Among the phthalatesanalyzed, di(2-ethylhexyl) phthalate (DEHP) was the most prevalent, with concentrations reachingup to 0.95 mg/kg. Bisphenol A (BPA) was the dominant bisphenol, detected at levels between0.01 and 0.02 mg/kg. Five photoinitiators—benzophenone, 1-hydroxycyclohexyl phenyl ketone,4-methylbenzophenone, 4-hydroxybenzophenone, and ethyl 4-dimethylaminobenzoate—werefrequently identified, indicating the contribution of printing inks and surface coatings ascontamination sources. In addition, perfluorooctanoic acid (PFOA) was detected in two samples,highlighting the potential presence of PFOA in disposable food-contact materials. The resultsunderscore the need for continued surveillance of food-contact materials and the implementationof stricter regulatory controls to reduce long-term consumer health risks.
