    A Retrospective Study of Tracheostomy Care and Decannulation of the Patients in a Palliative Care Center
    (Sage Publications inc, 2024) Zengin, Hilal; Karahan, Zehra Can; Can Karahan, Zehra
    Background: World Health Organization defines palliative care as a multidisciplinary approach to enhancing patients physical, psychological, and emotional well-being. Our study investigated palliative care unit decannulation rates and factors affecting success. Methods: The data of patients hospitalized in the palliative care clinic between 2017 and 2019 were analyzed retrospectively. Demographic data, diagnoses, comorbidities, nutritional status, Norton and Braden Scale scores, day of hospitalization, and discharge direction of the patients were recorded. All patients were evaluated and treated by a multidisciplinary team. Results: One hundred two tracheostomy patients were monitored. Patients in the palliative care clinic had an average stay of 22.19 +/- 13.67 days (median: 21, min: 4, max: 66). Forty-one patients were decannulated. Statistically significant age difference was observed between decannulated and non-cannulated groups, with the decannulated group having a significantly lower mean age (52.10 +/- 20.54, median: 53) compared to the non-decannulated group (61.48 +/- 18.07) (z = -2.516, P = .012). The mean Braden scale score of the decannulated group (14.29 +/- 2.50) was significantly higher than that of the non-decannulated group (12.20 +/- 2.82) (z = 3.823, P < .001), and the mean Norton scale score of the decannulated group (11.34 +/- 2.50) was significantly higher than that of the non-decannulated group (9.46 +/- 2.46) (z = 3.472, P = .001). Conclusion: Patients with tracheostomy can be easily followed and decannulated in palliative care clinics. It is important that a multidisciplinary team is involved in palliative care units. Age, immobility, Norton and Braden scales, and level of consciousness are factors affecting the success of decannulation.

    Development and Validation of an ICF-Based New Scale-Atilim Kinesiophobia Scale: A Methodological Study
    (Lippincott Williams & Wilkins, 2025) Ulug, Naime; Parmaksiz, Ayhan; Begen, Sena Nur; Can Karahan, Zehra; Yilmaz, Seval; Adali, Mehmet Fatih; Kilic, Erden; Er, Dudu Melek
    It is important to assess kinesiophobia, which increases the risk of disability by limiting physical activity. In this cross-sectional study, we aimed to develop a scale that assesses kinesiophobia with the multidimensional structure of International Classification of Functioning, Disability and Health (ICF). Atilim Kinesiophobia Scale (AKS) was developed in Turkish by an expert panel using questionnaires replied by 367 subjects. Finally, 38 questions based on the sub-domains of the ICF described by World Health Organization. In the scope of this cross-sectional study content validity and reliability were assessed; construct validity (both convergent and divergent validity) was checked against Tampa Kinesiophobia Scale-17 and Visual Analog Scale. AKS demonstrated good internal consistency and convergent validity, with significant correlations observed with the Tampa Scale for Kinesiophobia-17 (r = 0.478, P < .001). Divergent validity was supported by insignificant correlations with the Visual Analog Scale (r = 0.019, P = .855). The Cronbach alpha coefficient of 0.862 indicates a high level of internal consistency for the AKS. Based on these findings, the final version of AKS was refined to include 4 factors and 14 items, demonstrating good internal validity. We developed and validated the AKS to assess kinesophobia in patients with acute and/or chronic musculoskeletal pain. This new ICF-based scale can be used to assess kinesiophobia; however further studies are required to prove its validity and reliability in other languages.

    Does Reformer Pilates Exercise Improve Cognitive Functions in Sedentary Women? a Randomized Controlled Study
    (Elsevier, 2024) Ozeren, Aysenur; Ulug, Naime; Sahan, Nilay; Karahan, Zehra Can; Can Karahan, Zehra
    Background: The reformer is an apparatus on which to perform the foot work and the body in a comfortable, nonweight-bearing supine position and keeps the muscles in balance. The aim of this randomized controlled and single-center study was to investigate the effect of reformer Pilates exercises on cognitive functions in sedentary women. Methods: A total of 44 sedentary women aged between 24 and 50 were randomized into two groups. The reformer Pilates group received a 6-week exercise program (45 min/twice per week), while the control group didn't receive any exercise program. Outcomes measured before and after the interventions were, right/left discrimination and scores of two questionnaires: Stroop Test and The Pittsburgh SleepQuality Index. Results: Reformer pilates group showed significant improvement in terms of the Stroop Test (STROOP) "STROOP-B" (t0 = 156; p < 0.05; Cohen d = 0.12), "STROOP-C" (U = 144.5; p < 0.05; Cohen d = 1.13) and "STROOP-D" (U = 165; p < 0.05, Cohen d = 0.40) when compared to control group. In the comparison of the results of the right-left separation in both groups, the difference values were not statistically significant (p > 0.05). Similarly, in the both groups the sleep quality of the individuals improved, but the difference was not statistically significant (p > 0.05). Conclusion: The results of the current study suggest that Reformer Pilates exercises may be more effective on cognitive functions compared to no exercise intervention in sedentary women. Clinical Trial Number: NCT05932004.
