Is There a Relationship Between Sleep Quality, Dietary Intake and Weight Gain in Turkish Pregnant Women
No full textBackground Sleep quality, dietary intake, and body composition are known to change during pregnancy. This study aimed to examine the relationship between sleep quality, dietary intake and gestational weight gain in pregnant women. Methods This cross-sectional study was conducted between April and October 2023 in Istanbul, involving 214 healthy pregnant women aged 20-45 years who had no diagnosed medical conditions and were referred to a diet clinic by a physician. Sociodemographic information, anthropometric measurements, and 3-day food diaries were collected, and the Pittsburgh Sleep Quality Index (PSQI) was administered through a face-to-face questionnaire. Results Of the participants, 56.5% reported poor sleep quality. Body weight and body mass index (BMI) were significantly higher in those with poor sleep quality (p 0.05). Sleep quality did not vary with daily energy and macronutrient intake (p > 0.05). PSQI subscale analysis revealed that sleep disturbances in pregnant women were positively associated with energy (r = 0.137, p = 0.045), calcium (r = 0.147, p = 0.032), and copper (r = 0.139, p = 0.042) intake. Conclusions Sleep disturbances during pregnancy are positively associated with dietary intake and gestational weight gain. To prevent sleep disturbances, which are common in pregnant women, it is important to provide counseling on optimal weight gain and healthy nutrition starting from the preconception period.Science Citation Index Expande

No full textReklamlar günümüzün en hızlı tüketilen iletişim araçlarındandır. Reklam dünyasında her birey birer tüketici olarak düşünülmektedir. Genel olarak düşünce biçimine doğrudan etki etmeyi hedeflerler. Seyirciye ürünü sunmanın ötesinde bir yaşam tarzını benimsetme hedefi ile de yola çıkarlar. Böylelikle birey bir ürünü değil zihninde oluşan imgelemi satın almaktadır. Araştırmanın örneklemini, en iyi reklam filmi kategorisinde ödül alan “Apple” markasının “the Greatest (2023)” reklam filmi oluşturmaktadır. Reklam anlatısının çözümlenmesinde göstergebilimsel analiz yöntemi kullanılmıştır. Evrende yer alan göstergeler sınırsız olsa da nelerin analiz edileceğinin belirlenmesi için göstergebilim yöntemi önemli bir konumdadır. Araştırmanın bulgularına göre; reklam filminin gösterileni; \"Apple\" marka ürün kullanan bireylerin yaşamdan maksimum verim alabildikleridir. Yan anlam ise; seyirciye hem engellerin aşılabileceğini, eksiklerin tamamlanabileceğini göstermekte; hem de bu konforlu yaşama ulaşmak için gerekli ekonomik statüyü hatırlatmaktadır
İtirazın İptali Davasının Kısmi Dava Olarak Açılması Sorunu
No full textİtirazın iptali davası, alacaklı tarafından borçlunun ilamsız icra takibine yaptığı itirazı bertaraf ederek takibin devamını sağlamak amacıyla başvurulan hukuki yollardan biridir. Uygulamada sıkça rastlanan bu dava türüne ilişkin olarak son dönemde Yargıtay kararları doğrultusunda kısmi dava şeklinde açıldığına dair örnekler artış göstermektedir. Yargıtay’ın benimsediği yaklaşıma göre, borçlu takip talebinde yer alan alacak miktarının tamamına itiraz etmiş olsa dahi, alacağın yalnızca bir kısmı için itirazın iptali davası açılması mümkün görülmektedir. Bu kabul, itirazın iptali davasının icra hukukuna özgü yapısı, takibe sıkı sıkıya bağlı olması ve itirazın bölünmesinin mümkün olmadığı gibi hususlar gözetildiğinde söz konusu yaklaşımın isabetliliğini sorgulanır hâle getirmektedir. Bu çalışmada, itirazın iptali davasının kısmi dava olarak açılmasının hukuken mümkün olup olmadığı; mevcut yasal düzenlemeler, öğretideki görüşler ve yargı içtihatları çerçevesinde ele alınarak, konuya ilişkin değerlendirmelerimizle birlikte incelenmektedir. Netice itibariyle, bu davanın hukuki niteliği ile İcra ve İflas Kanunu’ndaki düzenlenme amacının doğru şekilde kavranması ve kısmi dava olarak açılmasından doğan sorunların giderilmesi amaçlanmaktadır
Evaluation of the Relationship Between Food Insecurity Tendencies Based on Economic Income Levels and Pesticide Knowledge Levels in Obese Individuals
No full textBu çalışmada, obez bireylerin ekonomik gelir düzeyine bağlı olarak gelişen besin güvencesizliği eğilimleri ile pestisit bilgi düzeyleri arasındaki ilişki incelenmiştir. Besin güvencesizliği, yalnızca yeterli ve dengeli gıdaya erişememe değil, pestisit gibi endokrin bozucu kimyasallarla kontamine olmuş gıdalara maruz kalma riski açısından da değerlendirilmiştir. Pestisit kalıntısı içeren besinlerin obezite riskiyle olan olası ilişkisi de ele alınmıştır. Tanımlayıcı tipteki bu çalışma, İstanbul'un Bakırköy, Zeytinburnu, Kadıköy ve Beykoz ilçelerinde bulunan normal kilolu, hafif kilolu ve obez 18-65 yaş aralığındaki toplam 387 birey ile yürütülmüştür. Katılımcılara; demografik özellikler, sağlık durumu, beslenme alışkanlıkları, besin tüketim kayıtları, Gıda Güvencesizliği Deneyim Ölçeği (FIES), Hanehalkı Besin Güvencesizliği Erişim Ölçeği (HFIAS) ve pestisit bilgi düzeylerini değerlendirmeye yönelik bir anket uygulanmıştır. Beslenmeye ayrılan aylık bütçeye göre bireyler 1. grup, kadınlar için 3979 TL ve erkekler için 4127 TL altında bütçe ayıranlar; 2. grup ise bu tutarların üzerinde bütçe ayıranlar olarak ikiye ayrılmıştır. BKİ ortalaması 25,58±4,47 kg/m2 olup, iki grubun BKİ ortalaması arasındaki fark istatistiksel olarak anlamlı bulunmamıştır (p>0,05). HFIAS ölçeğine göre katılımcıların %82,9'u, FIES ölçeğine göre %47,0'si besin güvenceli olarak sınıflandırılmıştır. Beslenme bütçesine göre her iki ölçekte de 1. grupta besin güvencesizliği riskinin anlamlı derecede daha yüksek olduğu saptanmıştır (p0,05). Pestisit bilgi düzeyleri normal kilolu ve hafif kilolu+obez gruplarında benzerlik göstermiştir (p>0,05). Pestisit kalıntılı sebze ve meyve yeme kaynaklı kaygı duymayan bireylerin BKİ ortalaması, kaygı duyanlara göre anlamlı düzeyde daha yüksek saptanmıştır (p=0,025). Besin güvencesi olan bireylerin pestisitler ve pestisit kalıntıları hakkında bilgi sahibi olma oranları, güvencesizlere göre anlamlı derecede daha yüksektir (FIES p=0,023; HFIAS p=0,003). Ayrıca, organik gıda tüketim sıklığı besin güvencesi olanlarda daha yüksek olup, güvencesizlerde anlamlı şekilde daha düşüktür (FIES p=0,041; HFIAS p=0,029). Pestisit kaygı düzeyine göre incelendiğinde, organik ürün tüketme isteğinin, pestisit kaygısı arttıkça arttığı gözlenmiştir (p0.05). According to the HFIAS, %82.9 of participants were classified as food secure, and according to the FIES, %647.0 were food secure. The risk of food insecurity was found to be significantly higher in Group 1 on both scales (p0.05). Similarly, BMI distribution did not differ significantly by pesticide knowledge level (p>0.05). However, the average BMI of individuals who did not express concern about pesticides was significantly higher than those who did (p=0.025). The proportion of food-secure individuals who are knowledgeable about pesticides and pesticide residues is significantly higher than that of food-insecure individuals (FIES p=0.023; HFIAS p=0.003). Moreover, the frequency of organic food consumption is significantly greater among those with food security compared to those without (FIES p=0.041; HFIAS p=0.029). When examined according to the level of concern about pesticides, it was observed that the desire to consume organic products increased as pesticide concern increased (p<0.001). The frequency of organic food consumption was higher in normal weight individuals compared to overweight and obese individuals. Pesticide exposure, which is one of the potential causes of obesity, should be addressed alongside food insecurity in the fight against rising obesity. Further advanced studies with larger samples are needed to better understand these relationships and to establish causality
Factors Influencing Hospital Length of Stay in Febrile Neutropenia: A Retrospective Cohort Study of Turkish Patients with Solid Tumors
No full textFebrile neutropenia (FN) is a severe complication of chemotherapy, asSociated with substantial mortality and financial burden. The purpose of this study was to assess the asSociation between hospital length of stay (LOS), supportive therapies, and antibiotic regimens in patients with FN, with a specific focus on the Turkish population. Eighty adult patients with solid tumors were enrolled. Patients received empirical antibiotic therapy within 2 hours of presentation. Data were collected on clinical and demographic variables, including LOS, fever duration, Multinational AsSociation of Supportive Care in Cancer Risk Index scores, and laboratory parameters. The mean hospital LOS was 6.09 +/- 3.62 days. Sulperazon use was significantly asSociated with a shorter LOS compared to meronem and tazocin (P < .001). Patients receiving filgrastim had a longer LOS compared to those who did not (P = .042). Correlation analysis revealed strong positive asSociations between LOS and febrile days (R = 0.624, P < .001), febrile days during hospitalization (R = 0.711, P < .001), and filgrastim administration days (R = 0.722, P < .001). Multivariate analysis confirmed that sulperazon use reduced LOS by 1.271 days (P = .048), while prolonged filgrastim use was linked to longer stays (P < .001). These findings highlight the critical role of antibiotic selection and supportive care in managing hospitalization duration for patients with FN. The combination of certain treatments and antibiotics plays a significant role in determining the duration of hospital stays, highlighting factors to consider in patient management and treatment planning.Science Citation Index Expande
Cluster and Correspondence Analyses for Oral Ulcer Activity Related Factors in Behçet's Syndrome
No full textBackground: Beh & ccedil;et's Syndrome (BS) is a multisystemic vasculitis characterized by a heterogeneous clinical profile, including mucocutaneous, musculoskeletal, neurological, ocular, vascular and gastrointestinal manifestations. BS patients often experience a continuous, low-level disease activity state due to persistent oral ulcers. This study aimed to define relations among oral ulcer activity (OUA), gender and treatments through K-Means Cluster and Correspondence Analyses (CA) in patients with BS. Material and Methods: In this cross-sectional study, 526 BS patients from two tertiary centres in Turkey and the United Kingdom were included. The K-Means Cluster Analysis was performed to identify homogeneous clinical profiles for OUA by combining the disease severity score reflecting organ involvement and the number of oral ulcers. Then, CA was performed to visualize associations between gender and medications (non-immunosuppressive: non-IS vs. IS) in clusters. Results: K-Means Analysis identified three clusters regarding mucocutaneous and major organ involvement and one with major organ involvement. Clusters were named according to OUA and the disease severity. The number of oral ulcers was found to be similar in the "Low OUA" cluster (n=202, 65.03%; 2.18 +/- 1.13) and the "Low OUA with Major Organ Involvement" cluster (n=63, 19.25%; 2.19 +/- 1.37)(p=0.368). These were lower than those in the "Moderate OUA" Cluster (n=30, 9.8%; 7.60 +/- 1.88) and the "High OUA" cluster (n=11, 3,59%; 14.91 +/- 2.34) (p<0.001). CA visualized that non-ISs in "Low OUA" cluster, ISs in "Low OUA with Major Organ" cluster for both genders as well as male patients treated with non-ISs or ISs in "Moderate OUA" cluster were predominant groups. Conclusions: The presence of two oral ulcers might be accepted as the cut-off value for low OUA. Moreover, intensive treatment protocols must be provided for elevated oral ulcer activity in male patients who were treated with non-IS medications in BS.Science Citation Index Expande
Cancer Rate in Pulmonary Embolism Diagnosed Cases: A Single-Center, Retrospective Study
No full textIntroduction: The aim of this study was to evaluate the incidence of pulmonary embolism in relation to age, cancer, and other comorbidities; to assess clinical, laboratory, and radiological findings; and to examine the associated mortality rate. Materials and Method: Patients diagnosed with pulmonary embolism were included in this single-center retrospective study. The patients were divided into two age groups: 60 years. The incidence of pulmonary embolism; presence of deep vein thrombosis, cancer, surgical history; other comorbidities; mortality rate; prevalence of embolism; and C-reactive protein and D-dimer levels were evaluated according to age group and sex. Results: Of the 1,281 patients who underwent pulmonary computed tomography angiography for suspected pulmonary embolism, 235 were diagnosed with pulmonary embolism. Of these, 114 were female and 121 were male. The mean age was 62.3 ± 16.8 years. In the ≥60 age group, the proportion of females was significantly higher than that of males (p < 0.05). Cancer prevalence and C-reactive protein and D-dimer levels were also significantly higher in this group (p < 0.05). No statistically significant differences were observed between the age groups for the other evaluated parameters. Conclusion: The incidence of pulmonary embolism is higher in the elderly population, and the presence of additional conditions, particularly cancer, further increases the risk of pulmonary embolism. Careful monitoring of elderly patients for comorbidities, risk factors, and complications—such as pulmonary embolism—is crucial. Early diagnosis and timely treatment play vital roles in reducing mortality and significantly improving quality of life.Science Citation Index Expanded - Social Science Citation Inde

No full textHuman-Centric Artificial Intelligence (HCAI) is a field of scientific study that concentrates on creating systems and finding solutions. Basically, HCAI is related with abstractions, theories, paradigms, Cognitive Ergonomics and Ethical Concepts. Depending on different factors in every country, HCAI can be used in different levels. The deployment of HCAI gives us the opportunity to consider the social aspects of the environment and consequently to comprehend the interaction between human and all other parameters. Cognitive ergonomies enriches the field of Human-AI collaboration by establishing a rather comprehensive framework. In Human-Centered Man-Machine System (MMS) Design it is not enough the emphasize optimizing the common area between individual operators and their immediate physical and psycho-social environment
Using CFD Analysis to Evaluate the Performance of a Natural Gas Compressor Under Different Geometries of Internal Parts
No full textNatural gas transmission networks in some countries are the main arteries of this energy source. Their extensiveness and the fluid properties of natural gas necessitate proper compression under all conditions. The design of pressure boosting stations and the operation prediction under different consumer demand conditions necessitate using several parallel compressors capable of different rotational speeds. In this study, a model of a heavy-duty centrifugal compressor used in these stations has been studied. First, using the finite volume method, the compressor is simulated with initial conditions and in three dimensions. Then, suggestions are made to modify the geometry of its various parts, and their effects under all flow rates and rotational speeds are examined. The impact of the number of blades/vanes in the impellers, the intermediate diffuser, and the inlet channel has been studied. The effect of using splitters has also been examined. The results show that although the use of splitters is not recommended, changing the number of blades/vanes in other parts can increase the efficiency of the compressor. Increasing the number of IGVs reduces the compressor power consumption by 5.9 %. Increasing the number of IBs from 15 to 18 for the first and second stages increases the outlet pressure by 2.93 % and 0.32 %, respectively. It also decreases the outlet entropy by 46.80 % and 28.45 %, respectively. It also decreased TKE in the first stage from 172.83J/K to 139.26J/K (19.99 %) and increased it from-52.73 to 4.77J/K in the second stage. Reducing the number of diffuser vanes to 19 increased the efficiency by 1.1 %. Reducing the number of IBs to 15 increased the efficiency by 2.55 %. In general, since the natural gas consumption flow rate has changed from the initial design condi-tions, and the performance improvement resulting from the proposed modifications is greater at higher flow rates, these changes are justified.Deanship of Research and Graduate Studies at King Khalid University [RGP2/464/46]The authors extend their appreciation to the Deanship of Research and Graduate Studies at King Khalid University for funding this work through Large Research Project under grant number RGP2/464/46.Science Citation Index Expande
Effect of Preclinical Training in Periodontal Instrumentation on Undergraduate Students' Anxiety, Clinical Performance, Satisfaction
No full textObjectives This study aims to assess the impact of preclinical training using instructional typodont-phantom head on undergraduate students' anxiety levels, clinical performance, and satisfaction. Materials & methods Sixty-fourth-year students from Istanbul Okan University with no clinical periodontal experience were randomly divided into two groups. Both groups received one hour of theoretical periodontal training on comprehensive examination and supragingival instrumentation. Group 1 received only theoretical training, while Group 2 additionally completed 60 min of hands-on preclinical training using a typodont-phantom head with artificial calculus. Before their first patient procedures, students completed a state anxiety test and afterward rated their training satisfaction on a VAS. Clinical performance was assessed using a scaling operation score sheet. Results Group 2 had significantly higher clinical performance (77.67 +/- 17.17) and satisfaction scores (8.23 +/- 1.79) compared to Group 1 (59.93 +/- 15.38 and 6.67 +/- 1.62, respectively; p < 0.05). No significant difference in state anxiety scores was observed between groups, nor any correlation between anxiety and clinical performance. Conclusion Preclinical training in periodontal instrumentation improved clinical performance and satisfaction but did not affect anxiety. Integrating theoretical and practical preclinical training with a typodont-phantom model can enhance learning outcomes. Clinical trial registration The study was retrospectively registered with ClinicalTrials.gov (ID: NCT06593873) on 10/09/2024.Science Citation Index Expande
