    Relationship Between Socio-Demographic Features, Work-Related Conditions, and Level of Anxiety Among Turkish Primary Health Care Workers
    Picakciefe, M; Turgut, A; Igneci, E; Cayli, F; Deveci, A
    The purpose of this study was to investigate the relationship among Turkish primary health care workers' socio-demographic characteristics, working conditions, and anxiety. A cross-sectional study was conducted with 88 of 103 (85.4%) eligible health care workers from the city of Mugla participating. The participants' average age was 31 years, 85.2% were university graduates, 30.7% were nurses, and 64.8% had been working between 11 and 20 years at the time of the study; 93.6% worked 8 hours each day or less. State anxiety scores for males (p = .016), health care workers age 31 or older (p = .035), nurse participants (p = .043), and individuals who had worked 11 or more years (p = .044) were significantly higher than the rest of the sample; however, trait anxiety scores for participants who did not work overtime and were not scheduled for shift work were significantly higher (p = .033 and p = .004, respectively) than the rest of the sample. According to the logistic regression analysis, risk factors for anxiety included being male and older than 31 years.

    Effect of 2.45 GHz Microwave Radiation on the Inner Ear: A Histopathological Study on 2.45 GHz Microwave Radiation and Cochlea
    Tahir, E; Karadayi, AA; Gürgen, SG; Engiz, BK; Turgut, A
    BACKGROUND: The present study aims to determine the possible low dose-dependent adverse effects of 2.45 GHz microwave exposure and Wi-Fi frequency on the cochlea. METHODS: Twelve pregnant female rats (n = 12) and their male newborns were exposed to Wi-Fi frequencies with varying electric field values of 0.6, 1.9, 5, 10 V/m, and 15 V/m during the 21-day gestation period and 45 days after birth, except for the control group. Auditory brainstem response testing was performed before exposure and sacrification. After removal of the cochlea, histopathological examination was conducted by immunohistochemistry methods using caspase (cysteine-aspartic proteases, cysteine aspartates, or cysteine-dependent aspartate-directed proteases)-3, -9, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). Kruskal-Wallis and Wilcoxon tests and multivariate analysis of variance were used. RESULTS: Auditory brainstem response thresholds in postexposure tests increased statistically significantly at 5 V/m and above doses. When the number of apoptotic cells was compared in immunohistochemistry examination, significant differences were found at 10 V/m and 15 V/m doses (F-(5,F-15) = 23.203, P =.001; Pillai's trace = 1.912, eta(2) = 0.637). As the magnitude of the electric field increased, all histopathological indicators of apoptosis increased. The most significant effect was noted on caspase-9 staining (eta(2)c9 = 0.996), followed by caspase-3 (eta(2)c3 = 0.991), and TUNEL staining (eta(2)t = 0.801). Caspase-3, caspase-9, and TUNEL-stained cell densities increased directly by increasing the electric field and power values. CONCLUSION: Apoptosis and immune activity in the cochlea depend on the electric field and power value. Even at low doses, the electromagnetic field in Wi-Fi frequency damages the inner ear and causes apoptosis.

    The influence of anesthesia- body mass index and chronicity of the injury on the reliability of diagnostic tests for anterior cruciate ligament rupture
    Bilgin, E; Turgut, A; Hancioglu, S; Sariekiz, E; Uzakgider, M; Kalenderer, Ö
    This study aimed to analyze the accuracy and interobserver reliability of the four common diagnostic tests for anterior cruciate ligament (ACL) rupture. The effect of anesthesia, chronicity of the injury and patient's body mass index (BMI) on the reliabilities was also assessed. Patients who underwent arthroscopic knee surgery were examined before the surgery and under anesthesia by three observers categorized based on their experience levels. One hundred two patients were evaluated to determine the accuracy of these tests. Sixty-two patients with ACL rupture were further examined to assess the effect of BMI ( <= 25 kg/m(2), or >25 kg/m(2)) and chronicity ( <= 4 or > 4 weeks) of the injury on reliabilities with using the Fleiss kappa method. The Lachman test performed under anesthesia had the highest sensitivity (100%,100%, and 963%). In contrast, pivot shift and lever sign tests had the lowest sensitivity both in awake (24.2%, 17.7%, 8.1% and 37.1%, 33.8%, 29%) and anesthetized condition (75.8%, 75.8%, 67.7% and 41.9%, 43.5%, 403%). Specificities of the tests except pivot shift were negatively affected when performed under anesthesia. The reliability of the anterior drawer test was perfect under anesthesia. The lever sign test had the highest reliability in the awake condition in patients with a BMI of >25 kg/m(2). Furthermore, the reliabilities of the anterior drawer, Lachman, and pivot-shift tests in awake condition were found to be increased in patients with a chronic injury. Finally, the examiner's experience is not important for the physical diagnosis of ACL rupture.
