Tıp öğrencileri, bilişsel ve akademik performansı olumsuz etkileyen sınav kaygısıyla mücadele etmektedir. Aromaterapi, farmakolojik tedavilere alternatif olarak popüler hale gelmektedir. Bu çalışma, ardıç ve kekik esansiyel yağlarının lisans öğrencilerinin sınav kaygısını psikofizyolojik olarak nasıl etkilediğini incelemektedir. Sınavlara giren öğrencilerde ardıç ve kekik aroması inhalasyonu asprosin, siklik guanozin monofosfat yanıt elementi bağlayıcı protein (CREB), kortizol ve sınav kaygısı üzerinde test edilmiştir. Yöntem: Tıp Fakültesi'nden 18-25 yaş arası 80 sağlıklı öğrencinin rastgele bir örneği, final sınavları sırasında toplanmıştır. Katılımcılar kendi kontrolleriydi ve aromaterapiden önce ve sonra tükürük alındı. Tükürük örnekleri ELISA kullanılarak Asprosin, CREB ve kortizol için test edildi. Kalp hızı, oksijen satürasyonu, sistolik basınç, diyastolik basınç ve vücut sıcaklığı aroma inhalasyonundan önce ve sonra izlenmiştir. Bulgular: Bu çalışmanın bulgularına göre, ardıç ve kekik aromaterapisinin tükürük ortalama Asprosin, CREB ve kortizol hormon düzeylerini artırmada etkili olduğu, en anlamlı düşüşün ise ardıç aromaterapisi alan gruplarda olduğu tespit edildi (p<0.001). Ardıç aromaterapi uygulaması Sistolik Kan Basıncı (SKB) ve Diyastolik Kan Basıncı (DKB)'yi etkilemiş (p<0.05) ancak Kalp Atım Hızı (KAH), Periferik Kapiller Oksijen Satürasyonu (SPO2) veya sıcaklığı etkilememiştir (p>0.05). Kekik aromaterapisi SBP, DBP, HR, SPO2 veya sıcaklığı etkilememiştir (p>0.05). Sonuç: Hafıza ve duyguları kontrol eden limbik sistem koku ile bağlantılıdır. Çalışmamız, koku inhalasyonunun sınav sırasında üniversite öğrencilerinde Asprosin, CREB, kortizol ve diğer fizyolojik göstergeleri etkilediğine dair özgün kanıtlar ortaya koymuştur ve sınav kaygısının giderilmesinde destekleyici bulgular sunmaktadır.

Background: The exam period is a period full of intense stress and anxiety that deeply affects cognitive and physiological responses for university students. Listening to music has the potential to protect cellular health and alleviate the negative effects of stress by affecting individuals' mood, and cognitive functions. This study aimed to investigate the differential effects of 528 and 432 Hz music frequencies on salivary BDNF, CREB, and GRP78 levels in young adults, along with their association with cognitive performance under exam-related stress. Methods: A total of 162 healthy university students were randomly assigned to three groups: no music (control), 528 Hz instrumental music, and 432 Hz instrumental music. Participants listened to music for 20 min, after which saliva samples were collected and analyzed for brain-derived neurotrophic factor (BDNF), glucose-regulated protein 78 (GRP78) and cyclic AMP response element-binding protein (CREB) levels using ELISA. Cognitive performance was assessed using the Stroop word-color test administered by medical doctor. Results: Exposure to 528 Hz music significantly increased salivary BDNF (3.84 [2.76–4.13]) and CREB levels (1.5 [1.38–1.59]) compared to control (p < 0.05), whereas GRP78 levels were elevated in the 432 Hz group (0.51 [0.47–0.58]) (p < 0.05). No significant differences were observed between groups in Stroop test performance. Conclusion: These findings suggest that specific music frequencies elicit distinct biological responses under exam-related stress, even in the absence of immediate cognitive performance differences. Salivary neurotrophic and stress-related biomarkers may offer valuable non-invasive insights into music's neuromodulatory effects. Trial Registration: ClinicalTrials.gov identifier: AMU-EC-8522.

Glossophobia (fear of public speaking, presentation anxiety) is an anxiety disorder characterized by extreme fear and anxiety about public speaking. Glossophobia is a very common phobia worldwide, reportedly affecting 75% of the population. This study aims to examine the effects of different aroma inhalations (Thyme and Juniper) on public speaking anxiety, and salivary cortisol hormone levels in university students. The sample of the research consisted of a total of 104 university students, male and female, between the ages of 18-20. In the first step, cortisol hormone levels were determined using the ELISA technique in the saliva samples taken from the university students included in the study. The average salivary cortisol hormone level and public speaking anxiety levels of the university students participating in the study showed a positive and statistically significant relationship (p=0.001). There is a significant negative correlation between the participants' public speaking anxiety and post-thyme oil status at a 99% confidence level and a 1% significance level, r=-.318. When public speaking anxiety and juniper oil were analyzed, a significant negative relationship was found at r=-.290, a 99% confidence level, and a 1% significance level. It was also concluded that inhalation of 2% thyme essential oil in individuals with high glossophobia is both safe and beneficial in reducing anxiety levels.

Orthorexia nervosa (ON) is a type of eating disorder marked by an excessive preoccupation with eating healthily to preserve and promote health, which surpasses normal levels of concern. This study aims to investigate the correlation between orthorexic tendencies, anthropometric measurements, and several other characteristics among university students. A cross-sectional study was done with a sample size of 307 university students from various departments, consisting of 228 females and 79 males. The data-gathering process consisted of administering a demographic information form and the ORTO-11 questionnaire. Anthropometric measurements, such as weight, height, waist circumference, hip circumference, and chest circumference, were measured. In addition, Body Mass Index (BMI) was calculated. The TANITA BC-418 equipment was used to measure the weight of the participants, while a flexible tape measure was used to measure their height, waist circumference, hip circumference, and chest circumference. The BMI was calculated by the individual's weight (in kilograms) by the square of their height (in meters). The data analysis encompassed the utilization of descriptive statistics, t-tests, variance analysis, and Pearson correlation analysis. A score of 25 or lower on the ORTO-11 scale was categorized as orthorexic, whereas a score higher than 25 was deemed normal. The average age and orthorexia scores of the subjects were 20.81±1.86 and 27.76±4.42 for females, and 21.38±4.14 and 28.11±4.37 for males, respectively. It was determined that 29.3% of the participants were found to display orthorexic tendencies, while the remaining 70.7% did not. There were no statistically significant variations in age, hip circumference, and orthorexia scores across genders (p>0.05). No statistically significant relationship was found between the total orthorexia scores and BMIs of the individuals (r=-.051, p>0.05). ON is associated with psychological and social complications, which in turn contribute to the development of disordered eating patterns. The results of this study indicate that determining the frequency of orthorexic tendencies among university students may contribute to the development of strategies for its prevention.
