Objectives The participants in this study are members of the class of 2020 at Panca Sakti University Bekasi's Economic Education Research Program. The purpose of this research is to investigate the influence that one's self-efficacy and perspective of the teaching profession have on one's level of motivation to enter the teaching profession. This study employs a survey or questionnaire approach to quantitative research with an associative approach, using multiple linear regression analysis to analyze the resulting data. A total of 104 students were selected at random for this analysis. According to the results, an individual's self-efficacy had a more significant influence on their interest in entering the teaching profession than did their perception of the teaching profession itself. If a person is interested in becoming an educator, one factor that goes into the decision-making process is how they feel about themselves in relation to the teaching profession and how confident they are in their abilities.

Reflections of Türkiye’s Enterprising and Humanitarian Foreign Policy Concept in Azerbaijan, Georgia and Armenia
Authors: YILMAZ Serdar
Published: August 2023

The concept of Entreprising and Humanitarian Foreign Policy, which includes hard and soft power elements, emphasizes the assertive, active and strong nature of Turkish foreign policy. At the same time, this Concept introduces Türkiye as a humanitarian state and draws attention to the cooperation, peace and development ties of her foreign policy. This study aims to explain Türkiye's South Caucasus policy with the concept of "Enterprising and Humanitarian Foreign Policy" adopted in 2018. With the disintegration of the Soviet Union in December 1991, Türkiye has played a leading role in recognizing the independence of the South Caucasus countries, providing economic and humanitarian aid, resolving conflict problems and mediating. Due to the new territorial alteration as Azerbaijan liberated the Karabakh region in 2020, Türkiye’s role has increased as she has strengthened her existing strategic relations and established new one. Therefore, the study is going to first elucidate the concept and the scope of this new policy and then look for an answer to the question: What has Türkiye done in the South Caucaus in line with the the concept of "Enterprising and Humanitarian Foreing Policy?"
Köroğlu Destanı’nın Maraş Rivayeti
Authors: ÖZÇELİK Bedri
Published: August 2023

Köroğlu Destanı, ortak Türk kültürünün abidevî bir şaheseridir. O, geçmişin millî hasletlerini bugüne ve geleceğe taşıyan kültür mirasıdır. Onun anlatıldığı geniş Türk dünyası coğrafyası düşünüldüğünde, milletin kültür bütünlüğünü oluşturmada ve korumada önemli bir görevi yerine getirdiğini söylemek mümkündür. Köroğlu Destanı, halk içinde fonksiyonel bir özellik taşıdığı ve anlatıldığı coğrafyalarla bütünleştiği için varlığını bugün de sürdürmektedir. Bir metnin folklor ürünü olduğunu ifade edebilmek için onun yaşatıldığı coğrafyaya yerleşmiş olması zorunludur. Destan kahramanının o coğrafyada doğup yaşamasından ziyade o kahramanla ilgili destanın söz konusu coğrafyada anlatılması önem kazanmaktadır. Bu yönüyle Köroğlu Destan’ı anlatıldığı ve dinlenildiği ortamların ihtiyacı ile şekillenen bir folklor ürünü olarak görülmektedir. Bu sebeple Türk dünyasında anlatılan Köroğlu Destanı’nın versiyonları birtakım farklılıklar göstermektedir. Versiyonlar arasındaki bu farklılıklar; kültürel, siyasî, dinî, ekonomik ve coğrafî etmenlere dayanmaktadır. Köroğlu Destanı’nın Maraş rivayeti de bu açıdan değerlendirildiğinde bir folklor ürünü olarak kabul edilmekte ve diğer versiyonlarla arasında bazı farklılıklar barındırmaktadır. Her folklor metni anlatılan toplumsal çevrenin ortak değeri olduğundan ve her coğrafya kendi ihtiyaçlarına göre bir Köroğlu meydana getirdiğinden Köroğlu Destanı’nın Maraş rivayeti de bu yörenin ihtiyaçlarına uygun olarak şekillenmiştir. Bu çalışmada Hacı Ali Özturan’ın derleyip yazıya geçirdiği “Maraş Ağzı Köroğlu” adlı eseri esas alınarak Köroğlu Destanı’nın Maraş rivayeti üzerinde durulmuştur. İlk önce söz konusu eser hakkında bilgiler verilmiş ve daha sonra da Maraş rivayetinin özeti sunulmuştur. Bütüncül yaklaşım yöntemiyle Köroğlu Destanı’ndaki destanî unsurlar, temalar ve motifler tespit edilmiştir. Çalışmanın amacı; Köroğlu Destanı’nın Maraş rivayeti üzerinde araştırma, inceleme ve değerlendirmeler yapmak, Türk kültür bilimi, Türk folkloru ve Türk edebiyatı için kıymet arz eden bu rivayeti ilim dünyasına tanıtmaktır.
Covid-19’lu Pediatrik Vakalardaki Toraks Tomografisi Bulgularının Yaşlara Göre Dağılımı , Thoracic computed tomography findings of pediatric COVID-19 cases according to age groups
Authors: TURAN ÖZSOY Hilal Gülsm , ORAL Behiye , KILIÇ İsa
Published: August 2023

Objective: In this study, we aimed to evaluate thoracic computed tomography (CT) findings of pediatric patients with novel coronavirus disease 2019 (COVID-19) pneumonia according to age groups.
Methods: A total of 105 patients aged between 0 and 18 years who were admitted to our clinic between April 2020 and September 2020 were retrospectively analyzed. The definitive diagnosis was established by reverse transcriptase-polymerase chain reaction (RT-PCR) testing of the combined nasopharyngeal/oropharyngeal swabs. The patients were divided into three groups according to age: 0-6, 6-12, and 12-18 years. Thoracic CT findings at the time of initial admission were evaluated.
Results: Of the patients, 51 had RT-PCR positivity for COVID-19, while 54 had RT-PCR negativity. Of the RT-PCR-positive patients, 30 (58.8%) had normal CT, while lung involvement was observed in 21 patients (41.2%). The most common thoracic CT findings were bilateral lung involvement (27.5%), lower lobe involvement (31.4%), nodular involvement (31.4%), and ground-glass opacity (37.3%). In the 6-12 age group, middle lobe involvement was significantly more frequent (p=0.041). The rate of consolidation significantly decreased with the increasing age (p=0.045).
Conclusion: The most common CT findings were bilateral, peripheral lower lobe involvement in pediatric COVID-19 cases. Consolidation was the most frequent lesion in the 0-6 age group, which can be attributed to the high incidence of bacterial co-infection. In the 12-18 age group, the distribution, morphology, and opacity of the lesions were comparable with those seen in adults. The lesions presented with nodular and ground-glass opacity patterns in the 6-12 and 12-18 age groups.

Published: August 2023

This study was to develop and validate a mobile application, the mindreading-ⓢ, that assesses young children’s social cognition abilities. A total of 445 children participated in the study and used the mindreading-ⓢ, while their caregivers filled in the Children’s Social Understanding Scale (CSUS), Social Cognition Checklist (SCC). The mindreading- ⓢ included 48 items and assesses seven sub-factors: joint attention, emotion, pretend, perception, desire, belief, and intention. After calculating the average correct answer rate and standard deviation, and analyzing reliability and item-total correlation, two items were deleted. To determine the likelihood of guessing, the difficulty, and the discrimination per item, IRT analysis was performed and six items identified as inappropriate were modified. Regarding construct validity, the mindreading-ⓢ showed reasonably positive correlations with CSUS and SCC. As a result, the mindreading-ⓢ was verified to be a reliable tool for assessing young children’s social cognition abilities.

Solidarity taxes: the latest EU experience and prospects for Ukraine
Authors:   Research and Development Centre for Industrial Problems of Development of NAS of Ukraine, IVANOV Yurij
Published: August 2023

Introduction. The development of the taxation theory and the best practices of the World Anti-crisis Tax Policy prove the gradual separation of an independent and very specific group of taxes, called “solidarity taxes”, which are beginning to play a fairly significant role in modern tax policy. The intensive development of solidarity taxes and their implementation in the European fiscal space in 2022 are closely related to the crisis phenomena that have arisen in the field of energy prices and the associated increase in the inflation rate. This is one of the consequences of the military aggression of the Russian Federation against Ukraine. Another consequence of this war was the high need for investment necessary for the revival of Ukraine. Problem Statement. The problems of the design of solidarity taxes and their scope of application, as well as the possibilities and features of their use as a promising source of investment financing, remain insufficiently studied. And the latest experience of the second half of 2022-early 2023 regarding the coordinated application of taxes on unpredictable profits in EU countries requires critical analysis and generalization. Purpose. To study the economic content, evolution and regulatory framework of the application of solidarity taxes in the EU and the prospects for their implementation in Ukraine at the stage of post-war economic recovery. Methods. The author used analytical and qualitative research methods, including logical and comparative analysis, to identify general and special features of solidarity taxes, decomposition and grouping methods to study the element base and identify models of the studied taxes. Results. The theoretical basis and European practice of using solidarity taxes are analyzed, and the genesis of their development in the EU countries is studied. The principles of development and implementation of a common tax policy within the EU to counteract the consequences of the energy crisis through the introduction of a temporary contribution of solidarity, coping with unexpected profits in the energy sector and oil refining are considered. Attention is focused on the expediency, limitations and risks of the prospective application of solidarity taxes as its own source of investment financing at the stage of the post-war economic recovery of Ukraine. Conclusions. Solidarity taxes implementation is a promising direction for creating our own national sources of investment financing in the context of the post-war economic recovery. The introduction of solidarity taxes in Ukraine requires the adaptation of the European methodology to the specifics of the set goals and conditions of taxation in Ukraine, as well as scientific justification of restrictions on the application of this tax and preventive mechanisms to counteract the negative consequences of its implementation.

Published: August 2023

Adventure tourism has experienced significant growth in recent years and offers benefits to both rural communities and environmental conservation. Therefore, this study aims to characterize the profile, estimated expenditure, perception of economic impact, and satisfaction of adventure tourists visiting Valle del Jerte in Extremadura, Spain, for canyoning activities. Possible differences generated by the gender of tourists on these issues were analyzed. The sample included 673 tourists who practiced canyoning in Valle del Jerte. Statistical tests were used to analyze gender differences in variables such as means of transport used, intention to spend, type of expenditure, and need for public investment. Significant differences were found in the gender of the participants, with men having the highest expenditures. These findings are relevant for public and private organizations as well as for the local community, as they allow them to offer more adequate services to tourists who carry out these activities and attract more visitors.

Authors: DEMİRTÜRK SELÇUK Ezgi , DEMİRBAĞ Birsel Canan
Published: August 2023

Objective: This research was carried out to determine the attitudes of individuals who applied to primary care during the coronavirus disease-2019 (COVID-19) pandemic and the factors affecting the COVID-19 vaccine.

Methods: The descriptive study was conducted with individuals (n=190) who applied to five family health centers in Erzincan city center between March-June 2021. The data were collected using the "Personal Information Form" and the "Scale of Attitudes towards the COVID-19 Vaccine" by paying attention to the pandemic rules by face-to-face interview method.

Results: It was determined that 75.3% of the individuals were women, 41.1% were primary school graduates, 59.5% lived in a nuclear family and 74.2% had no chronic disease. Individuals Attitudes Towards COVID-19 Vaccine Scale mean score was 3.26±0.78 out of 5, positive attitude sub-dimension mean score was 3.32±0.99, and negative attitude sub-dimension mean score was 3.21±0.71. There is a statistically significant difference between the mean scores of the Attitudes Towards COVID-19 Vaccine Scale and the status of individuals thinking that COVID-19 vaccine is necessary for public health, worrying about getting COVID-19 infection, having COVID-19 vaccine, and following information about COVID-19 vaccine.

Conclusions: It was determined that the attitudes of these individuals towards the COVID-19 vaccine were at a positive level. The reasons for participants' concerns about the COVID-19 vaccine are fear of side effects of the vaccine and the production of the vaccine in a very short period of time.
Trends in SAVR with biological vs. mechanical valves in middle-aged patients: results from a French large multi-centric survey
Authors: Caus Thierry , Chabry Yuthiline , Nader Joseph , Fusellier Jean François , De Brux Jean Louis ,   for the EpiCard investigators
Published: August 2023

Background/introduction

Currently, despite continued issues with durability (
1), biological prosthetic valves are increasingly chosen over mechanical valves for surgical aortic valve replacement (SAVR) in adult patients of all ages, at least in Western countries. For younger patients, this choice means assuming the risks associated with a redo SAVR or valve-in-valve procedure.

Purpose

To assess the use of mechanical vs. biological valve prostheses for SAVR relative to patient's age and implant time in a large population extracted from the French National Database EPICARD.

Methods

Patients in EPICARD undergoing SAVR from 2007 to 2022 were included from 22 participating public or private centers chosen to represent a balanced representation of centre sizes and geographical discrepancies. Patients with associated pathology of the aorta (aneurysm or dissection) and requiring a vascular aortic prosthesis were excluded. Comparisons were made amongst centers, valve choice, implant date range, and patient age.

Results

We considered 101,070 valvular heart disease patients and included 72,375 SAVR (mean age 71.4 ± 12.2 years). We observed a mechanical vs. biological prosthesis ratio (MBPR) of 0.14 for the overall population. Before 50 years old (y-o), MBPR was >1.3 (p < 0.001) while patients above 60 years-old received principally biological SAVR (p < 0.0001). Concerning patients between 50 and 60 years-old patients, MPVR was 1.04 (p = 0.03). Patients 50–60 years-old from the first and second study duration quartile (before August 2015) received preferentially mechanical SAVR (p < 0.001). We observed a shift towards more biological SAVR (p < 0.001) for patients from the third and fourth quartile to reach a MBPR at 0.43 during the last years of the series. Incidentally, simultaneous mitral valve replacement were more common in case of mechanical SAVR (p < 0.0001), while associated CABGs were more frequent in case of biological SAVR (p < 0.0001).

Conclusion

In a large contemporary French patient population, real world practice showed a recent shift towards a lower age-threshold for biological SAVR as compared to what would suggest contemporary guidelines.
Risk evolution and mitigation of the urban river ecological governance project based on social network analysis
Authors: Xu JunKe , Zhu Jiwei , Xie JianCang
Published: August 2023

This study aims to utilize complex network theory and network immune strategies to identify relevant risks in urban river ecological governance projects and develop corresponding risk response strategies. By constructing a risk evolution network with 53 nodes and 255 edges, we analyzed the network’s degree centrality, betweenness centrality, closeness centrality, and composite value parameters, confirming the network’s scale-free characteristics. Based on this, we used network global efficiency as a metric to assess the network’s robustness under random and targeted attacks. The results revealed that under targeted attack scenarios, the degree value attack immune strategy performed optimally, while random immune strategies were less effective than targeted immune strategies. Moreover, this model offers various advantages in early risk response decision-making and establishing a forward-looking risk warning framework, providing an effective tool for risk management in urban river ecological governance projects.
Prediction of mining-induced seismicity and damage assessment of induced surface buildings in thick and hard key stratum working face: a case study of Liuhuanggou coal mine in China

Published: August 2023

Thick and hard key stratum working faces are characterized by frequent mine tremors and significant ground tremors during mining which seriously threaten the safety production of the mine. With working face (4-5) 06 of Xinjiang Liuhuanggou Coal Mine as the engineering background, using field investigation, microseismic monitoring, and theoretical analysis, a mining-induced seismicity prediction method and damage assessment of surface buildings for thick and hard key stratum working faces is proposed, which is based on the evolution characteristics of overlying strata spatial structure and the motion state of the key stratum. The results of the study are as follows: 1) The movement law of overlying strata is the basis of mining-induced seismicity prediction for working faces. The magnitude of the risk of mining-induced seismicity occurrence is mainly related to the boundary conditions of the working face, the thickness of the key stratum, the distance from the coal seam to the key stratum, the height of the overlying strata spatial structure, and the fracture step of the key stratum. 2) The mining-induced seismicity energy contains the original accumulation elastic energy of the key stratum, the transfer elastic energy of low rock strata, and the accumulation elastic energy of gravity work. Based on this, a mechanical model of surface building damage induced by the release of mining-induced seismicity energy was established. A ground vibration damage boundary and vibration induction boundary under the action of strong mining-induced seismicity were proposed, and the service life of buildings when they reach the critical damage value under the action of frequent mining-induced seismicity was obtained. 3) The temporal and spatial distribution law of mining-induced seismicity activities in thick and hard key stratum working faces was revealed. According to the results of micro-seismic monitoring, the “zonality” characteristics of the time series and the “transition” law of spatial distribution of mining-induced seismicity verified the reliability of the mining-induced seismicity prediction method. The research results provide a theoretical basis for predicting mining-induced seismicity and assessing the risk of induced disasters during the mining process of thick and hard key stratum working faces, and can provide technical support for mining-induced seismicity prevention and control and safety production in mines with similar conditions.

Published: August 2023

Introduction

Creativity is an important 21st-century skill that also plays an important role in second language use and development. This study examined the effects of creative pedagogy centered on student questioning activities for second language learners’ creativity, language proficiency, and questioning ability.

Methods

In the Japanese second language course, a creative activity intervention involving questioning activities was conducted for 81 university students. The students were taught how to ask higher-order questions, and they performed questioning activities and discussions about their questions after reading articles for eight lectures in 4 weeks.

Results

After the intervention, the quantity and quality of questions asked by participants increased and improved in the Questioning ability test. In the Creative thinking test, the three subscales of creative thinking (fluency, flexibility, and originality) improved after the intervention. In the Language proficiency test, there were also significant changes in vocabulary, grammar, and total scores after the intervention compared to before the intervention.

Discussion

The creative pedagogy significantly improved learners’ creativity, second language performance, and questioning ability, with a particularly positive impact on questioning ability, representing innovative thinking skills. The findings of this study not only contribute to future research on the development of creativity in second language instruction and deepen the exploration of the development of questioning ability for innovative thinking skills.
From barriers to boosters: initial teacher education for inclusive science education
Authors: Fränkel Silvia , Sterken Moritz , Stinken-Rösner Lisa
Published: August 2023

The paper presents a literature review on current barriers and boosters in the context of initial science teacher education for inclusion. The authors argue that current science teacher education programs for prospective teachers could be improved by adopting a more conceptually grounded and sustainable approach toward inclusion. To this end, the paper proposes an approach based on inclusive values and evidence-based practices that would benefit all students. Firstly, the paper identifies several barriers that exist in current science teacher education programs, including the dominance of anadd-on approach, separate teacher education tracks, and inadequate preparation for the topic leading to decreasing self-efficacy toward inclusion. Secondly, to overcome these barriers, the paper proposes the integration of evidence-based practices, collaboration, and knowledge-transfer in science teacher education programs. These boosters can equip prospective science teachers with the necessary skills and knowledge for effective inclusive science education. Overall, the paper provides valuable insights and recommendations for improving initial science teacher education programs in the context of inclusion.

In the modern workforce, environmental scholars and professionals need a working technical knowledge of complex social-environmental issues and a mastery of interpersonal skills like leadership, communication, and collaboration. This article reflects on a special topics course offered to undergraduate students in Fall 2021, titled “Survey of Environmental Organizations.” Pre- and post-course surveys were given to assess student experiences and outcomes. Results of paired t-tests and open-ended responses show that students gained confidence in their career prospects, developed and practiced professional skills, and benefitted from opportunities to network with professionals in their desired field(s). The principal contribution is a framework for educators who may want to integrate professional skills and career readiness into courses or programs in environmental science.

In Brazil, daycare as a social and economic reality for many families is consolidated as a natural context for the child and complementary to the family, and places teachers as important partners within an integrated system that involves the care of children from zero to 3 years old in the promotion of their full development. The experiences lived in daycare are decisive and fundamental in the child development process, and teachers as agents of intervention must be alert to possible early signs of change in the child’s development. However, the practices of Brazilian daycare teachers have been little investigated with regard to school inclusion. In this sense, this research aimed to investigate the experiences of daycare teachers with children who present risk signs for Autism Spectrum Disorder (ASD). This is a qualitative exploratory research, with the participation of 10 teachers from public daycare centers in a city in the state of São Paulo. The information was obtained through semi-structured interviews that followed a script previously defined by the researchers. Data analysis was carried out using thematic content analysis. The results pointed out that the teachers’ conceptions about development, permeated by their own ideas about education, care, family, and society, imply directly in their practices with the child and in the conduction of the case to other spheres. It was possible to verify the protagonism of the teachers who have in their effective practices care and play as intervention strategies in their actions. Gaps emerged regarding the communication between education professionals and the articulation between education and health. We identified the need for consistent intersectoral actions that favor the development of children who show early signs of ASD and value the role of the teacher in this process, also promoting inclusive educational practices.

Background

The guideline recommended chest compression depth, rate, and recoil are essential factors for the return of spontaneous circulation (ROSC) in cardiopulmonary resuscitation (CPR). A pediatric resuscitation collaboration recently demonstrated that healthcare providers fail to meet the American Heart Association (AHA) guidelines, with the greatest difficulty being in achieving chest compression depth targets in infants. We hypothesized that the use of the heel of one hand [open palm technique (OPT)] will increase chest compression depth in infants compared to standard CPR techniques [two-finger technique (TFT), two thumb-encircling hand technique (TTT)].

Methods

A prospective, randomized, single-center study was completed using an infant manikin. Thirty pediatric critical care providers performed 2 min of CPR for each technique followed by 5 min of rest. Each participant completed a survey at the end that assessed the difficulty level in order to assess the feasibility of this new technique.

Results

The mean chest compression depth for the OPT was significantly deeper compared to TFT (2.61± 0.63 cm vs. 2.25 ± 0.54 cm, p = 0.0004) but not significantly deeper compared to TTT (2.43 ± 0.46 cm, p = 0.0820). OPT was graded as the easiest technique, followed by TTT (2.20 ± 0.76 vs. 3.17 ± 0.95, p < 0.0001) and then TFT (3.38 ± 0.83, p < 0.0001).

Conclusion

The use of OPT for infant CPR resulted in improved chest compression depth. OPT was considered the easiest technique compared to standard infant CPR techniques, thus making it feasible to perform. Importantly, all providers failed to meet the AHA infant chest compression depth goal of 4 cm, regardless of the technique. Future research is needed to optimize CPR technique and performance to achieve targeted chest compression depth in infants.

Current guidelines recommend temozolomide as the first-line chemotherapy for aggressive pituitary neuroendocrine tumours. However, no clinical trials have been conducted to date and clinical experience is quite limited. We retrospectively analyzed 28 patients (9 women and 19 men), aged 46.6 + 16.9, with aggressive pituitary tumours (4 pituitary carcinomas and 24 aggressive adenomas) treated with temozolomide in 10 Spanish pituitary reference centres. Four patients had Cushing’s disease, 9 prolactinomas and 15 clinically non-functioning pituitary tumours (seven silent corticotroph, three silent somatotroph, one silent lactotroph, one silent gondotroph and three null-cell tumours). Median size at diagnosis was 10.5 cm3 (IQR 4.7-22.5), with cavernous sinus invasion in 88% and no metastases. Pre-temozolomide treatment, these data were 5.2 cm3 (IQR 1.9-12.3), 89.3% and 14.3% (2 intracranial and 2 spinal metastases). All patients had undergone surgery (1-5 surgeries), 25 (89.3%) had received radiotherapy (7 of them reirradiated) and 13(46.4%) had received cabergoline. One patient interrupted temozolomide prematurely. The remaining 27 patients received a median of 13 cycles (range 3-66) of 5 days every 28 days, with a mean initial dose of 265 ± 73 mg when administered alone and of 133 ± 15 mg when co-administered with radiotherapy. Eight patients (29.6%) had a significant reduction (>30%) in tumour volume and 14 (51.9%) attained tumour stabilization. After a median follow-up of 29 months (IQR 10-55), 8 out of these 22 showed disease progression. A longer progression-free survival was found in the five patients who received concomitant radiotherapy. Seven patients (25%) died (all of them because of tumour progression or complications of treatments) at 77 months (IQR 42-136) after diagnosis and 29 months (IQR 16-55) after the first dose of temozolomide. Adverse effects occurred in 18 patients (14 mild and 4 moderate or severe). In conclusion, temozolomide is an effective medical treatment for aggressive pitNET and pituitary carcinomas but is sometimes followed by tumour progression. Co-administration with radiotherapy may increase progression-free survival.

Introduction

The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide. Strategies to decrease this risk should be strongly encouraged. Lactation has been associated, for the mother, with reduction in future T2DM risk in several studies. The mechanisms behind this phenomenon, however, are poorly understood. The aims of this study were, first, to compare blood glucose levels and markers of insulin resistance (MIR) in early postpartum women with overweight/obesity according to their breastfeeding status and, second, to evaluate whether prolactin (PRL) levels could mediate improvements in these parameters.

Methods

The prospective study followed 95 women older than 18 years from early pregnancy for up to 60 to 180 days postpartum. All participants had a BMI > 25 kg/m2 and a singleton pregnancy. At each visit, questionnaires and clinical and biochemical evaluations were performed. Participants were divided into two groups according to the breastfeeding status as “yes” for exclusive or predominant breastfeeding, and “no” for not breastfeeding.

Results

Breastfeeding women (n = 44) had significantly higher PRL levels [47.8 (29.6–88.2) vs. 20.0 (12.0–33.8), p< 0.001]. They also had significantly lower fasting blood glucose levels [89.0 (8.0) vs. 93.9 (12.6) mg/dl, p = 0.04], triglycerides (TG) [92.2 (37.9) vs. 122.4 (64.4) mg/dl, p = 0.01], TG/HDL ratio [1.8 (0.8) vs. 2.4 (1.6) mg/dl, p = 0.02], TyG index [8.24 (0.4) vs. 8.52 (0.53), p = 0.005], fasting serum insulin [8.9 (6.3–11.6) vs. 11.4 (7.7–17.0), p = 0.048], and HOMA-IR [2.0 (1.3–2.7) vs. 2.6 (1.6–3.9), p = 0.025] in the postpartum period compared to the non-breastfeeding group. Groups were homogeneous in relation to prevalence of GDM, pre-gestational BMI, as well as daily caloric intake, physical activity, and weight loss at postpartum. Linear regression analysis with adjustments for confounders showed a statistically significant association of breastfeeding with fasting blood glucose [−6.37 (−10.91 to −1.83), p = 0.006], HOMA-IR [−0.27 (−0.51 to −0.04), p = 0.024], TyG index [−0.04 (−0.06 to −0.02), p = 0.001], and TG/HDL ratio [−0.25 (−0.48 to −0.01), p = 0.038]. Mediation analysis showed that PRL did not mediate these effects. Sensitivity analyses considering different cutoffs for PRL levels also did not show modification effect in the mediation analyses.

Conclusion

Breastfeeding was associated with improvement in glucose metabolism and MIR 60 to 180 days after birth in overweight and obese women, even when adjusted for confounders. PRL levels were not found to mediate the association between breastfeeding and improvement in MIR.
