The aim of this study was to evaluate the effects of different frequencies of dietitian-led nutrition counseling on dietary intake, anthropometric measurements, biochemical parameters, and blood pressure in individuals diagnosed with metabolic syndrome (MetS). The study was conducted using a randomized, controlled, three-arm design with a follow-up period of 12 weeks. Participants were allocated into three groups. In Group 1, participants received nutrition counseling at baseline and at weeks 4, 8, and 12. In Group 2, in addition to the same face-to-face counseling sessions, nutrition counseling was also provided via telephone during weeks 1–3, 5–7, and 9–11. Group 3 reflected routine clinical practice and received nutrition counseling only at baseline and after 12 weeks. Dietary intake was assessed using 24-hour dietary recalls. Anthropometric measurements, biochemical parameters, and blood pressure were evaluated using standard and appropriate methods. In the statistical analysis, nutrient intake data, anthropometric measurements, biochemical parameters, and blood pressure values obtained from monthly face-to-face visits were analyzed using repeated-measures ANOVA. The relationship between the number of nutrition counseling sessions and MetS criteria was assessed using Spearman correlation analysis. A linear regression model was constructed to examine the effect of the number of counseling sessions on the number of MetS criteria.The findings showed that although there were no differences among groups in dietary intake at baseline, energy, carbohydrate, and fat intake were significantly lower in Groups 1 and 2 compared with Group 3 at the end of the follow-up period (p=0,002; p=0,002; p=0,016, respectively). Similarly, while no baseline differences were observed among groups in fasting plasma glucose and diastolic blood pressure, both parameters were significantly lower in Groups 1 and 2 than in Group 3 at the end of the study (p<0,001; p=0,013, respectively). In the regression model in which change in the number of MetS criteria was set as the dependent variable, each one-unit increase in the number of nutrition counseling sessions was associated with a 0,055-unit decrease in the number of MetS criteria (R²=0,163; F(5,78) = 3,039; p = 0,015). In conclusion, more frequent dietitian-led nutrition counseling as part of medical nutrition therapy in individuals with MetS is associated with improvements in dietary habits as well as key MetS parameters, including fasting plasma glucose and diastolic blood pressure. These findings suggest that regular and more frequent nutrition counseling may enhance the effectiveness of MetS management.
ARTIRILMIŞ GERÇEKLİK DESTEKLİ HAREKETLİ BİLİMSEL İLLÜSTRASYON: HACETTEPE ÜNİVERSİTESİ BİYOSFER MÜZE ÖRNEĞİ

In this thesis, it is aimed to develop an interactive and augmented reality–supported digital exhibition approach that supports traditional exhibition methods by integrating motion graphics into scientific illustration drawings in biodiversity museums. Within the scope of the study, the theoretical foundations, historical development, methods, types, and application areas of scientific illustration were examined; additionally, the interaction possibilities of using two-dimensional motion graphics together with scientific illustration were explored. Considering the dynamic and multilayered nature of biodiversity, particularly in relation to animal species, the contribution of transforming static visuals into dynamic representations through virtual imagery was investigated.
The application project was carried out for the Biosphere Museum within the Hacettepe University Biodiversity Research and Application Center (HUBİOM), and scientific illustrations were prepared for four animals: the Anatolian leopard, brown bear, blue whale, and Tyrannosaurus Rex. In this context, drawings were produced to reflect the skeletal structure, muscular system, and external morphological features (skin, fur) of the animals. The prepared illustrations were supported with augmented reality technology and transformed into experiential content accessible to museum visitors. In addition, audio narrations accompanying the illustrations were provided to offer listening-based learning opportunities for visually impaired individuals. Species-specific behaviors of the selected animals were animated using two-dimensional motion graphics. These animations, which can be viewed and listened to on mobile devices, were enriched with the animals’ natural sounds and environmental atmosphere. The prepared content was designed to be presented to museum visitors via mobile devices.
As a result of the study, it was observed that the combined use of scientific illustration with motion graphics and augmented reality technologies enriches the museum experience, increases visitors’ interaction with exhibition objects, and supports the learning process.

This European consensus statement on essential colposcopy provides standards for the general colposcopist seeing women referred for colposcopy with an abnormal cervical screening test (including cytology and HPV tests) or with a clinically suspicious cervix. The article gives guidance regarding the aims and conduct of colposcopy. Recommendations are provided on colposcopy technique, the management of common colposcopy issues, treatment and follow-up of after treatment of CIN or early stage cervical. Colposcopists should make an informed decision on the management of each individual that is referred and organize appropriate follow-up. Cervical cancer is still a major health issue and the quality of care can only improve if there is a structured guidance for women with an abnormal smear or suspicious cervix.

Objective: To evaluate the clinicopathological features and outcomes of patients undergone surgery for benign and metastatic adnexal masses during the surveillance of colorectal cancer (CRC).
Methods: A single institute retrospective study involving 90 patients diagnosed with CRC that undergone surgery at Hacettepe University Hospital between 2000-2018. Clinicopathological and survival data was obtained from hospital records.
Results: Elevated blood levels of CEA (HR, 1.23; 95 % CI: 1.03-1.24; p = 0.01), adnexal masses larger than 5 cm (HR, 3.296; 95 % CI: 1.527-7.076; p = 0.002), bilaterality of adnexal mass (HR, 2.200; 95 % CI: 2.464-11.969; p = 0.001) and high PCI score (HR, 0.150; 95 % CI: 0.044-0.479; p = 0.01) were found to be significantly associated with ovarian metastasis. There was a significant difference in overall survival (OS), with respect to complete and incomplete resection in adnexal surgery of ovarian metastasis (46.6 vs. 29.6 months; p = 0.004). The median survival time was 32.8 months for patients with ≤ 24 months interval time to adnexal metastasis surgery, and 48.5 months for patients with >24 months interval time to adnexal metastasis surgery (p = 0.001).
Conclusion: This study showed that numerous clinicopathological variables such as bilaterality and size of adnexal mass, serum blood levels of CEA and PCI score may have a significant impact on the prediction and management of ovarian masses diagnosed during CRC surveillance. Complete resection and interval time to adnexal surgery is significantly associated with OS.

Objective: To investigate the clinicopathologic characteristics, prognostic factors, outcome, and treatment of the neuroendocrine carcinoma (NEC) of the endometrium.
Materials and methods: We retrospectively reviewed the clinicopathologic and survival data of 10 patients who underwent surgery for NEC. The patients were collected between 1999 and 2017 from four referral centers in Turkey.
Results: The median age of patients was 67 years (range: 34-75 years). The NEC of endometrium consist of 9 cases with small cell carcinoma (SC) NEC (two with mixed histotypes), and one with a large cell (LC) NEC. According to FIGO 2009 criteria, 70 % (7/10) of patients had advanced stage (III and IV) disease. All patients except one underwent surgical staging, eight patients received platinum-based chemotherapy (CTX) and of 6 those were additionally treated with radiotherapy (RT). Four patients died of disease ranging from 2 to 10 months and six were alive 12-72 months with no evidence of disease. In addition, 4 SC NEC cases raised in polypoid features had no evidence of disease from 24 to 72 months.
Discussion: NEC of the endometrium is a rare disease with poor prognosis, which frequently diagnosed in advanced stages. The main treatment modality was the administration of platinum-based CTX as an adjuvant to surgery or surgery and RT. Our result suggests that the polypoid feature of the tumor might be one of the best predictors for the prognosis of SC NEC.
