Article The Assessment of the Vaginal Discharge of Pregnant Patients With a Prior History Of Treatment For Vaginal Discharge During Pregnancy(2023) Kömürcü, Nuran; Dinmez, Sinem GüvenAmaç: Çalışmada vajinal akıntı yakınmasıyla tedavi görmesine karşın doğum sırasında benzer şikayetleri devam eden gebelerin, tedavi süreçlerini etkileyen faktörleri değerlendirmek amaçlanmıştır. Gereç ve Yöntem: Araştırma tanımlayıcı tipte tasarlanmıştır. Araştırmanın örneklemini, doğuma gelen gebelerden; araştırmaya katılmayı gönüllü olarak kabul eden, gebeliğinde en az bir kez vajinal akıntı şikayeti ile doktora başvuran, doktor tarafından vajinal akıntıya tedavisine başlanmış olan, travaydaki muayene sırasında aktif olarak akıntısı devam eden 222 gebe oluşturmuştur. Veri toplama aracı olarak ‘‘Vajinal Akıntısı Olan Gebelere Yönelik Değerlendirme Formu’’ kullanılmıştır. Veriler değerlendirilirken tanımlayıcı istatistiksel metodların yanı sıra niteliksel verilerin karşılaştırılmasında Pearson ki-kare ve Fisher’s Exact Test kullanılmıştır. Bulgular: Gebelerin; vajinal akıntılarının başlama zamanlarının birinci trimester (%43.7) ve ikinci trimesterde (%40.5) birbirine yakın olduğu, %62.2’sinin gebelik öncesi dönemde de vajinal akıntı öyküsü olduğu, gebelerin %86.0’sının akıntı başladıktan bir süre sonra doktora başvurduğu, %52.3’ünün tedavisini tamamladığı ve çoğunluğun (%70.7) orta düzeyde hijyene önem verdiği görülmektedir. Gebelerin eğitim ve hijyen düzeyleri arasında istatistik olarak anlamlı fark saptanmıştır (p<0.05). Sonuç: Gebelerin genital yol enfeksiyonları konusunda hijyenik uygulamalara verdikleri önemin yetersiz olduğu, tedaviye başlamak için geç kaldıkları ve tedavi kullanımı konusunda yanlış ve eksik uygulamalarda bulundukları görülmüştür. Buradan hareketle sorunun çözümüne katkı sağlayabilecek hemşirelerin/ ebelerin eğiticilik görevini üstlenerek konuyu bütüncül yaklaşımla ele alması gerektiği düşünülmektedir.Article The Correlation Between Vitamin D Levels and Thyroid Functions in Early Pregnancy(Yuzuncu Yil Universitesi Tip Fakultesi, 2025) Dinmez, Sinem; Özlem, Dülger; Oğul, Zeynep; Dülger, ÖzlemVitamin D deficiency (serum vitamin D <10 ng/ml) and thyroid dysfunctions are prevalent issues globally, particularly during pregnancy. Evidence suggests a potential link between thyroid function and vitamin D levels. This study aims to investigate the correlation between serum vitamin D levels and thyroid functions in wome n during the first trimester of pregnancy. The study was conducted retrospectively at a University Education and Research Hospital’s pregnancy clinic, covering data from August 2023 to March 2024. The sample group consisted of first -trimester pregnant women who attended routine pregnancy check-ups and had complete vitamin D levels and thyroid function tests (n=185). The sociodemographic data form and blood serum level assessment forms were used as data collection tools. The data were analyzed using descriptive statistics and correlation analysis. The average age of the pregnant women participating in our study was 27.6±4.9 years, and the Body Mass Index (BMI) was 25.4±4.8 (overweight). The mean number of pregnancies was 1.13±0.3, and the gestational week was 8.19±1.8. Of the participants, 35 had subclinical hypothyroidism, 37 had thyroiditis, and 113 had normal thyroid functions. The study identified 36 women with normal/adequate vitamin D levels (≥20 ng/ml), 113 with vitamin D insufficiency (10–20 ng/ml), and 36 with vitamin D deficiency (<10 ng/ml). The correlation analysis revealed no significant relationship between the thyroid function tests and vitamin D levels of the pregnant women. It was determined that vitamin D levels do not affect thyroid gland function in the first trimester.Article Assessment of Breastfeeding Self-Efficacy in Nursing Mothers Following Earthquakes: A Case Study of the Kahramanmaraş Earthquakes in Turkey(Kashan Univ Medical Sciences, 2025) Dinmez, Sinem Guven; Karaman, Ozen Esra; Bakir, EmineBackground: Natural disasters disproportionately impact vulnerable populations, particularly mothers and infants. Research indicates that during such events, mothers often favor formula and supplementary feeding over breastfeeding. Self-efficacy is a critical determinant influencing breastfeeding practices in disaster contexts.<br /> Objectives: This study aimed to examine the breastfeeding characteristics and self-efficacy of nursing mothers following the Kahramanmara & scedil; earthquakes.<br /> Methods: This descriptive study was conducted at the Children's Polyclinic of Iskenderun State Hospital in Turkey from August 1 to August 31, 2023. A total of 54 mothers with infants aged 0-1 year at the time of the earthquake, who continued to breastfeed (providing breast milk for at least one feeding), were selected using a non-probability purposive sampling method. During the study period, all eligible mothers visiting the polyclinic who met the inclusion criteria were evaluated. Data were collected using a "Descriptive Data Form" and the "Breastfeeding Self-Efficacy Short Form Scale". Statistical analyses were performed using SPSS version 23, employing Independent Samples t-tests, Mann-Whitney U tests, and One-Way ANOVA for group comparisons. A P-value of less than 0.05 was considered statistically significant.<br /> Results: The mean breastfeeding self-efficacy score among mothers was 58 +/- 5.87 (minimum 40; maximum 70). Mothers who exclusively breastfed their infants had significantly higher self-efficacy scores compared to those who introduced formula (P = 0.021) Among the mothers surveyed, 81.5% reported that their breastfeeding was affected by the earthquake; 41% cited issues related to privacy, while 27% faced challenges regarding shelter. Prior to the earthquake, 72% of infants were exclusively breastfed; however, this figure decreased as 81.5% of infants began receiving complementary foods alongside breast milk post-earthquake.<br /> Conclusion: The findings indicate that mothers breastfeeding self-efficacy is at a moderate level. Additionally, mothers reported alterations in their breastfeeding practices compared to the pre-earthquake period. These results underscore the importance of promoting breastfeeding in disaster-affected areas and highlight the critical role of midwives in supporting these efforts.<br />Article Comparative Cross-Sectional Study on Sexual Function of Couples During Pregnancy: Assisted Reproductive Techniques Versus Spontaneous Conceptions(Womens Health & Action Research Centre, 2024) Dulger, Ozlem; Dinmez, Sinem; Torun, Sebahat D.; Osmanoglu, Usame O.This study aims to compare the sexual functions of couples undergoing assisted reproductive techniques (ART) with those conceiving spontaneously during pregnancy. A total of 102 couples participated in this cross-sectional study, with 68 couples in the spontaneous conception group and 34 couples in the ART group. Data collection was conducted face-to-face in the antenatal clinic using separate "Descriptive Information Form" for women and men, "Female Sexual Function Index (FSFI)" for women, and "Libido Scoring System (LSS)" for men. Descriptive statistical methods, Chi-square and Fisher exact tests, t-test, and Pearson correlation test were used for data analysis. It was observed that the mean FSFI total scores of women who conceived spontaneously and through ART during pregnancy were at a good level (>= 30), while the mean LSS scores of their partners were at a moderate level (5-7). No statistically significant distinction existed among the groups. Further research is advisable by adjusting the sample selection criteria, such as gravida, duration of ART treatment, and gestational age.Article Associations of Nutrition Knowledge with Dietary Preferences, Symptom Burden, and Quality of Life in Women with Polycystic Ovary Syndrome(Frontiers Media SA, 2026) Yalcin Celiktas, Bahar; Çelikayar, Melike Nur; Dinmez, Sinem; Çeliktaş, Bahar Yalçın; Altıntaş, EslemPolycystic ovary syndrome (PCOS) is a complex endocrine disorder in which lifestyle-related factors are closely linked to symptom burden and quality of life. Although nutrition knowledge is frequently emphasized in PCOS management, its association with symptom severity and quality of life remains unclear. This web-based analytical cross-sectional study examined associations between nutrition knowledge, diet-related preferences, lifestyle behaviors, symptom burden, and quality of life among 330 Turkish women aged 18-45 years with a self-reported physician diagnosis of PCOS. Nutrition knowledge and diet-related preferences were assessed using validated instruments, quality of life was assessed using the SF-12, and symptom burden was summarized using an index derived from a PCOS-related symptom checklist. Higher body mass index was associated with greater symptom burden and poorer physical health, whereas regular physical activity was associated with better physical functioning. Nutrition knowledge was positively associated with healthier diet-related preferences but was not associated with symptom burden or quality of life. In multivariable analyses, body mass index remained the strongest predictor of symptom burden, while nutrition knowledge and diet-related preferences were not significant contributors. These findings indicate a knowledge-outcome disconnect in PCOS, suggesting that higher nutrition knowledge may align with healthier preferences without corresponding improvements in health outcomes. Because dietary intake and eating behaviors were not directly measured, conclusions regarding behavior should be interpreted cautiously. Public health and women's health interventions may benefit from integrating nutrition education with behavior change support, weight management, and physical activity promotion.Article Covid-19 Tanısı Almış Gebelerin Tanı, Tedavi, İzlem Süreçleri ve Gebelerin Hastalığa Yaklaşımları(2023) Dinmez, Sinem; Eroglu, KafiyeAmaç: Bu araştırma Covid-19 tanısı almış gebelerin tanı, tedavi, izlem süreçleri ve gebelerin hastalığa yaklaşımlarını belirlemek amacıyla yapılmıştır. Gereç ve Yöntem: Retrospektif tanımlayıcı tipte olan çalışma, İstanbul’un bir ilçesinde Covid-19 nedeniyle izlenen 68 gebe üzerinde yapılmıştır. Veriler ‘‘Covid-19 ile Enfekte Olmuş Gebeleri Değerlendirme Formu’’ ile toplanarak, tanımlayıcı istatistiksel yöntemlerle analiz edilmiştir. Bulgular: Gebelerin çoğunlukla ikinci ve üçüncü trimesterde enfekte oldukları, tomografi ve sürüntü testi ile tanı aldıkları, en sık halsizlik, öksürük semptomları yaşadıkları belirlenmiştir. Gebeler 15 günden daha uzun süre evlerinde izole olup, yarıya yakını tıbbi tedavi almamıştır. En sık korku ve çaresizlik hissettiklerini ifade etmişlerdir. Gebelerin yarısı gebelik izlemlerine daha az gittiklerini, sezaryen doğumu tercih ettiklerini belirtirken yarıya yakını gebelikle ilgili işlemlerini aksattıklarını belirtmiştir. Gebelerin çoğunluğu bebeklerini emzirmeyi planladıklarını ifade etmiştir. Sonuç: Covid-19’la enfekte olan gebelerin bu süreçte gebeliğin rutin izlem ve uygulamalarından yararlanamadıkları, ruhsal desteğe ihtiyaç duydukları ve normal doğum fikrinden uzaklaştıkları saptanmıştır. Gebelik izlemleri ve danışmanlık için hemşirelerin online izlem gibi alternatif uygulamaları başlatmaları önerilir.Article The Effect of a Theory of Planned Behavior-Based Education Model on Self-Management and Metabolic Control in Pregnant Women with Gestational Diabetes: A Randomized Controlled Trial(2026) Eroğlu, Kafiye; Dinmez, Sinem GüvenBACKGROUND: Gestational diabetes mellitus (GDM) is a common pregnancy complication associated with adverse maternal and neonatal outcomes. Lifestyle modification is central to GDM management; however, optimal strategies for supporting self-management remain unclear. This study evaluated the effect of a personalized Theory of Planned Behavior (TPB)-based online education model supported by motivational interviewing (MI) on behavioral determinants and metabolic control in women with GDM. METHODS: This randomized controlled trial was conducted in a public maternity hospital in Istanbul, Türkiye, with 66 pregnant women with GDM (intervention: n = 33; control: n = 33). Data were collected using the Gestational Diabetes Intention, Attitude, and Behavior Questionnaire (GDIAB-Q), a sociodemographic and clinical form, and medical records. Co-primary outcomes were changes in five GDIAB-Q subscales (attitude, subjective norm, perceived behavioral control, intention, and planning). Secondary outcomes included metabolic parameters (postprandial blood glucose, HbA1c, lipid profile, blood pressure, and body mass index). The intervention group received three TPB-based online sessions with MI during gestational weeks 28-30; controls received usual care. Effect sizes (Cohen's d) and 95% confidence intervals were calculated. The study was registered at ClinicalTrials.gov (NCT04874922). RESULTS: The predefined theory-informed success criterion for the co-primary outcome set was met. Significant between-group improvements were observed in attitude (d = 0.71, 95% CI: 0.21-1.21, p = 0.005), subjective norm (d = 0.80, 95% CI: 0.30-1.30, p = 0.002), and intention (d = 0.56, 95% CI: 0.06-1.05, p = 0.028). No significant differences were found for perceived behavioral control or planning. Secondary outcomes favored the intervention, with lower postprandial blood glucose (d = 0.51, p = 0.045), HbA1c (d = 0.50, p = 0.045), and BMI (d = 0.59, p = 0.021). CONCLUSION: This TPB-based online education model strengthened key behavioral determinants of self-management and was associated with early improvements in selected metabolic outcomes among women with GDM. Theory-driven, personalized education may support GDM self-management; longer-term follow-up is needed to assess sustained effects.
