Öğe Evaluation of lavender essential oils and by-products using microwave hydrodistillation and conventional hydrodistillation(Nature Research, 2024) Kırkıncı, Seran; Gercek, Yusuf Can; Baştürk, Fatma Nur; Yıldırım, Nazlıcan; Gıdık, Betül; Bayram, Nesrin EcemThis study investigated the impact of two extraction methods, traditional hydrodistillation (TDH) and microwave-assisted hydrodistillation (MAH), on the essential oil yield and chemical profile of Lavandula angustifolia L., as well as the bioactive potential of the resulting wastewater. Essential oil composition was analyzed via GC–MS, revealing similar qualitative and quantitative profiles for both methods, with ?-terpinolene and (–)borneol as major constituents. Wastewater analysis via LC–MS/MS and spectrophotometric assays demonstrated the presence of significant total phenolic content (3.29–1.78 mg GAE/g) and 32 individual phenolics (463.1 µg/kg for TDH; 479.33 µg/kg for MAH). These findings suggest that both essential oil and wastewater obtained by either method possess considerable bioactive potential, with the MAH method potentially offering advantages over TDH for essential oil extraction. Further exploration of wastewater applications in various industrial sectors is warranted. © The Author(s) 2024.Öğe Effect of kangaroo mother care and white noise on physiological-stress parameters in heel lancing: randomized controlled study(BioMed Central Ltd, 2024) Kirbaş, Zila Özlem; OdabaşI Aktaş, Elif; Bayraktar, Bülent; Özkan, HavaBackground: Newborns are exposed to varying degrees of stressful interventions due to procedures such as heel lancing used in routine metabolic screenings. It is an examination of the effects of white noise and kangaroo care on some physiological parameters and stress markers (cortisol and glucose-regulated protein 78-GRP78) in heel lancing in newborns. Methods: Randomized controlled study was conducted at a gynecology service of a hospital between January and September 2023. 90 babies were divided into three groups: 30 babies in the Kangaroo Care Group (KCG), 30 babies in the White Music Group (WMG), and 30 babies in the Control Group (CG). All babies were randomly divided into groups. Stress parameters were measured by saliva collection method and physiological parameters by saturation device. Results: A statistically significant difference was determined between the total crying time, pulse and saturation values ??according to the groups (p < 0.001; p = 0.001). A statistically significant difference was determined between the mean values ??of cortisol and GRP78 measurements according to group and time interaction (p < 0.001). KCG was more effective in reducing total crying time and stabilizing pulse, saturation, salivary cortisol, GRP-78 values compared to WNG and CG. Conclusion: It was concluded that white noise and kangaroo care help reduce newborns’ stress in the case of heel lancing. Practical implications: The practice of kangaroo care and the use of white noise methods may assist healthcare professionals as supportive methods in stress management during invasive procedures.

However, research on the transition to motherhood in Turkish society is scarce. There is a need for a comprehensive, practical and reliable tool to evaluate the transition to motherhood in primiparous mothers. This study evaluated the reliability and validity of the Turkish version of the Transition of Primiparous Becoming Mothers Scale (TMP-S) to evaluate the transition process of primiparous mothers to motherhood. Methods This methodological research was carried out in obstetrics and gynecology outpatient clinics, pediatric outpatient clinics, and family health centers of a hospital in Turkiye. The sample consisted of primiparous mothers of 0 to 6- month-old babies who visited clinics and family health centers for routine postnatal examinations (n = 305). After evaluating the language equivalence and content validity of the scale, test-retest reliability, internal consistency and construct validity were examined. Factor analysis, Pearson's correlation, retest reliability, and Cronbach's alpha were employed to evaluate structural validity and reliability. Results The final TPM-S had two dimensions with 25 items. Exploratory factor analysis revealed a two-factor solution, which accounted for 59.276% of the variance. Confirmatory factor analysis showed that the model fit of the two-factor model also reached a satisfactory model ft after modification. The comparative fit index was 0.894, the Tucker-Lewis index was 0.882, and the root mean square error of approximation was 0.079. The content validity index of the scale ranged from 0.56 similar to 0.77. The Cronbach's alpha coefficient was 0.93 for the total scale, and the test-retest reliability was 0.96. Conclusions It is a valid and reliable tool for evaluating the transition to motherhood among primiparous mothers of 0 to 6 month-old babies in Turkiye. Turkish researchers and healthcare professionals can routinely apply this measurement tool to primiparous mothers in the first six months after birth to evaluate their transition to motherhood.Öğe Utilisation of an active branching sucrase from Lactobacillus kunkeei AP-37 to produce techno-functional poly-oligosaccharides(Elsevier, 2023) Ispirli, Huemeyra; Korkmaz, Kader; Arioglu-Tuncil, Seda; Bozkurt, Fatih; Sagdic, Osman; Tuncil, Yunus Emre; Narbad, ArjanGlucansucrase AP-37 was extracted from the culture supernatant of Lactobacillus kunkeei AP-37 and character-istics of the glucan produced by the active glucansucrase in terms of structural and functional roles were determined in this study. A molecular weight around 300 kDa was observed for glucansucrase AP-37 and its acceptor reactions with maltose, melibiose and mannose were also conducted to unveil the prebiotic potential of the poly-oligosaccharides formed via these reactions. The core structure of glucan AP-37 was determined by 1H and 13C NMR and GC/MS analysis which revealed that glucan AP-37 was a highly branched dextran composing of high levels of (1-+ 3)-linked alpha-D-glucose units with low levels of (1-+ 2)-linked alpha-D-glucose units. The structural features of the glucan formed, demonstrated that glucansucrase AP-37 was an alpha-(1-+ 3) branching sucrase. Dextran AP-37 was further characterised by FTIR analysis and XRD analysis demonstrated its amorphous nature. A fibrous compact morphology was observed for dextran AP-37 with SEM analysis whereas TGA and DSC analysis revealed its high stability as no degradation was observed up to 312 degrees C. Finally, the prebiotic potential of the dextran AP-37 and the gluco-oligosaccharides produced with the acceptor reaction of alpha-(1-+ 3) branching sucrase AP-37 were determined and promising results were found for the gluco-oligosaccharides to act as prebiotics.Öğe Validity and Reliability of the Turkish Version of the Death Literacy Index(Sage Publications Inc, 2024) Semerci, Vahide; Sari, Ebru Soenmez; Seven, AhmetDeath literacy is defined as a set of knowledge and skills that make it possible to gain access to, understand, and act upon end-of-life and death care options. This study was conducted to test the validity and reliability of the 29-item original version of the Death Literacy Index (DLI) in Turkish society. The scale was applied on a sample of 436 Turkish adults determined using the snowball sampling method. Explanatory and confirmatory factor analyses were performed. The scale consisted of 6 subscales. The test-retest analysis of this study showed a strong and highly significant positive correlation between overall DLI (.98) and its subscales (.73-.98). The total Cronbach's alpha reliability coefficient of DLI was found to be .90. It was observed that the Turkish version of DLI was a valid and reliable tool and suitable for use in Turkish society.Öğe Validity and reliability of the Turkish version of the insomnia catastrophizing scale(Springer Japan Kk, 2021) Kabadayi, Fedai; Mercan, Oguz; Yazici-Kabadayi, Sema; Elhatip, Yaser Emir; Buyuksevindik, BakiInsomnia catastrophizing has attracted attention in recent years. Individuals may have started to recognize the importance of evaluating the consequences of insomnia, which has worsened during the coronavirus disease 2019 (COVID-19) pandemic. The present study aimed to test the validity and reliability of the Insomnia Catastrophizing Scale (ICS) in the Turkish young adult population. The study group consisted of a total of 387 participants: 57 in the pilot study and 330 in the main study. The majority of the participants in the study were females. According to the results of the confirmatory factor analysis, the single-factor structures of the ICS nighttime and daytime forms were confirmed to be the same as in the original structure, and the fit indices were above the acceptable limits. The ICS forms had very high reliability. The findings of the present study showed that the Turkish daytime and nighttime forms of the ICS are valid and reliable instruments. The results provide a means of measuring insomnia catastrophizing for use in therapeutic and counseling settings for Turkish young adult population. We also propose that mental health practitioners should design interventions to reduce insomnia catastrophizing in Turkish culture.Öğe Utilization of Response Surface Methodology in Optimization of Proline Extraction from Castanea sativa Honey(Wiley-V C H Verlag Gmbh, 2023) Bayram, Nesrin Ecem; Kutlu, Naciye; Gercek, Yusuf CanProline constitutes approximately 85 % of the amino acid composition of honey. Therefore, the quantitative determination of this amino acid in honey samples is used by many national/international authorities to evaluate the quality of honey types. In this study, it was aimed to achieve maximum proline amino acid extraction from honey samples whose botanical origins were confirmed by melissopalynological analysis. For this reason, based on three different spectrophotometric methods used in the literature for proline analysis, proline extraction was optimized with the Response Surface Method (RSM) and Box-Behnken experimental design. Three independent variables were determined as treatment time (2, 6, and 10 min), treatment temperature (22, 46, and 70 degrees C), and cooling time (5, 25, and 45 min). As a result of the optimization, it was seen that only significantly effective independent variable on the proline content of honey was the processing temperature. The optimum conditions obtained as a result of the RSM were found to be 2 min for the treatment time, 70 degrees C for the treatment temperature and 45 min for the cooling time. The composite desirability of the optimum conditions (R-2) was found to be 1.00. It was determined that the method proposed by International Honey Commission (IHC) is efficient for proline analysis, but it provides more proline extraction by reducing of time from 10 min to 2 min in hold time in boiling water bath only during the extraction step. As a result, the conditions to be used in order to achieve maximum proline extraction with different spectrophotometric methods were determined and optimum values were determined. In addition, since the botanical origin of honey samples significantly affects the proline content of honey, it can be suggested that this study be optimized for different monofloral honey samples as well.Öğe Ultrasound-assisted deep eutectic solvent extraction of bioactive compounds from persimmon calyx(Wiley, 2024) Kutlu, Naciye; Kamiloglu, Aybike; Abca, Tugba Elbir; Yilmaz, OzlemThis study aimed to investigate the ultrasound-assisted extraction of bioactive compounds from persimmon (Diospyros kaki) calyx by deep eutectic solvents (DES) with different molar ratios. For this reason, the prepared DES extracts' total phenolic-flavonoid compounds and antioxidant activities (1,1-diphenyl-2-picrilhydrazyl radical scavenging activity [DPPH center dot], Cupric Reducing Antioxidant Capacity (CUPRAC), and ferric reducing antioxidant power [FRAP]) were investigated as a result of the experimental design and optimization study conducted for this purpose. A sonication time of 20 min was determined as the optimal condition. Under these conditions, a molar ratio of 1.9:1 (lactic acid:choline chloride) and a water ratio of 70% provided the highest phenolic/flavonoid compounds and antioxidative activity. Correlations among water ratio, molar ratio, and sonication time were determined using principal component analysis (PCA). In conditions where total flavonoid compound, FRAP, and DPPH center dot are high due to PCA, it can be concluded that the sonication time is at high level; on the contrary, the water and molar ratios are at low level. In conclusion, ultrasound-assisted extraction using DES proved effective in persimmon calyx. Therefore, it can be recommended to use these environmentally friendly green solvents as an alternative to organic solvents in preparing extracts in various fields. Practical Application: This study shows the effectiveness of the ultrasound-assisted green extraction method using persimmon calyx specified as waste. These findings are compelling in the food industry in terms of consumers being now aware of green technology and the discovery that calyx is a good source of bioactive compounds.Öğe Turkish validity and reliability of the Haptotherapeutic Well-Being Scale(Bmc, 2024) Kucukkaya, Burcu; Isik, Hafsa Kubra; Rathfisch, GulayObjectives Haptotherapy fosters a sense of unity between the body, mind, and emotions. In addition, it contributes to expanding the woman's perception of her pregnancy and developing a more positive attitude towards pregnancy and childbirth. The study aims to examine the Turkish validity and reliability of the Haptotherapeutic Well-Being Scale, which will be used to evaluate the well-being levels of haptonomy and haptotherapy practices in women. Design The study was methodological type. Methods The study conducted between October 20 and December 20, 2023, with 242 women who volunteered to participate by sharing forum pages on social media (Facebook, Instagram) via the web.

This study examines the relationship between the ability to say << no >> and parental awareness of sexual abuse in 4th grade primary school students. Methods: The study was conducted between April 2022 and June 2022 in primary schools in the central district of a province in north-eastern Turkey. The sample consisted of 310 students enrolled in 4th grade and their parents. We collected the data through a personal information form, the ability to say << no >> scale for children and the sexual abuse awareness scale for parents. Results: There was a weak positive correlation between the mean maternal scores of sexual abuse awareness and the mean scores of refusal and resistance in children (P < .05), as well as a weak positive correlation between the mean paternal scores of sexual abuse awareness and the mean scores of refusal and resistance in children (P < .05). Conclusion: As mothers' and fathers' awareness of sexual abuse myths and of teachings and actions to combat sexual abuse increased, the refusal of children also increased. Also, as fathers' awareness of the signs of sexual abuse increased, children's refusal increased. (c) 2024 Asociaci & oacute;n Espa & ntilde;ola de Pediatr & iacute;a.

The anti-inflammatory properties of propolis are attributed to caffeic acid phenethyl ester (CAPE), which is present in European propolis. The objective of the conducted study was to assess the anti-inflammatory effects of the Polish ethanolic extract of propolis (EEP) and isolated CAPE on stimulated with LPS and IFN-alpha, as well as the combination of LPS and IFN-alpha. The cytotoxicity of the tested compounds was determined using the MTT assay. The concentrations of specific cytokines released by the HGF-1 cell line following treatment with EEP (25-50 mu g/mL) or CAPE (25-50 mu g/mL) were assessed in the culture supernatant. In the tested concentrations, both CAPE and EEP did not exert cytotoxic effects. Our results demonstrate that CAPE reduces TNF-alpha and IL-6 in contrast to EEP. Propolis seems effective in stimulating HGF-1 to release IL-6 and IL-8. A statistically significant difference was observed for IL-8 in HGF-1 stimulated by LPS+IFN-alpha and treated EEP at a concentration of 50 mu g/mL (p = 0.021201). Moreover, we observed that CAPE demonstrates a stronger interaction with IL-8 compared to EEP, especially when CAPE was administered at a concentration of 50 mu g/mL after LPS + IFN-alpha stimulation (p = 0.0005). Analysis of the phenolic profile performed by high-performance liquid chromatography allowed identification and quantification in the EEP sample of six phenolic acids, five flavonoids, and one aromatic ester-CAPE. Propolis and its compound-CAPE-exhibit immunomodulatory properties that influence the inflammatory process. Further studies may contribute to explaining the immunomodulatory action of EEP and CAPE and bring comprehensive conclusions.Öğe The melatonin agonist ramelteon attenuates bleomycin-induced lung fibrosis by suppressing the NLRP3/TGF-?1/HMGB1 signaling pathway(Elsevier Urban & Partner Sp Z O O, 2023) Aydin, Pelin; Aksakalli-Magden, Zeynep B.; Civelek, Maide S.; Karabulut-Uzuncakmak, Sevgi; Mokhtare, Behzad; Ozkaraca, Mustafa; Alper, FatihPurpose: The possible effects of ramelteon, a melatonin receptor agonist on bleomycin-induced lung fibrosis were analyzed via transforming growth factor beta 1 (TGF-beta 1), the high mobility group box 1 (HMGB1) and Nod-like receptor pyrin domain-containing 3 (NLRP3) which are related to the fibrosis process. Materials and methods: Bleomycin (0.1 mL of 5 mg/kg) was administered by intratracheal instillation to induce pulmonary fibrosis (PF). Starting 24 h after bleomycin administration, a single dose of ramelteon was administered by oral gavage to the healthy groups, i.e. PF + RM2 (pulmonary fibrosis model with bleomycin + ramelteon at 2 mg/kg) and PF + RM4 (pulmonary fibrosis model with bleomycin + ramelteon at 4 mg/kg) at 2 and 4 mg/kg doses, respectively. Real-time polymerase chain reaction (real-time PCR) analyses, histopathological, and immunohistochemical staining were performed on lung tissues. Lung tomography images of the rats were also examined. Results: The levels of TGF-beta 1, HMGB1, NLRP3, and interleukin 1 beta (IL-1 beta) mRNA expressions increased as a result of PF and subsequently decreased with both ramelteon doses (p < 0.0001). Both doses of ramelteon partially ameliorated the reduction in the peribronchovascular thickening, ground-glass appearances, and reticulations, and the loss of lung volume. Conclusions: The severity of fibrosis decreased with ramelteon application. These effects of ramelteon may be associated with NLRP3 inflammation cascade.Öğe The impact of surgical intervention on religious coping, psychological well-being, and pain levels in older adult patients: A quasi-experimental study(Mosby-Elsevier, 2024) Dastan, Buket; Kulaka, NursenAim: This study aimed to determine the impact of surgical intervention on religious coping, psychological well-being, and pain levels in older adult patients. Method: The data of the study, which used a one-group pretest-posttest quasi-experimental design without a control group, was collected between July 1, 2023, - January 30, 2024. Data collection involved the use of a Personal Information Form, the Religious Coping Scale, the Psychological Well-Being Scale, and the Visual Analog Scale. Results: The results revealed a significant increase in psychological well-being and positive religious coping after surgical intervention compared to presurgical levels (p < 0.001). Multiple linear regression analysis revealed that male gender, younger age, enhanced psychological well-being, and positive religious coping were identified as factors contributing to a reduction in postsurgical pain levels. Conclusion: The study's results indicate that surgical intervention serves as a significant variable influencing psychological well-being and religious coping among older adult patients.

Interrupted by the COVID-19 pandemic, which led to a suspension of in-person education, the study resumed in September 2021, refocusing on the effects of pandemic-induced inactivity on the physical fitness levels of the same cohort.Methods The study included twenty-nine male high school students (age: 17,24 +/- 0,73 years), divided into thirteen athletes (participating in sports such as football, basketball, and track) and sixteen non-athletic counterparts. They underwent reassessment using the ALPHA test battery, evaluating cardiorespiratory, musculoskeletal, and motor skills fitness. Data were analyzed using independent and paired samples t-tests and a two-way repeated measures ANOVA to assess changes over time and between groups. Discriminant function analysis evaluated the ALPHA test's ability to classify students based on their athletic status pre- and post-pandemic.Results Initially, athlete students exhibited significantly better BMI, 20 m shuttle run, and 4 x 10 m speed run scores compared to their non-athlete peers. After the pandemic, only the 20 m shuttle run scores remained significantly higher for athletes, with diminished distinctions in other fitness areas. The classification accuracy of the ALPHA test battery decreased from 89.7 to 75.9% post-pandemic.Conclusion The enforced sedentary lifestyle due to the COVID-19 pandemic adversely affected all students, particularly diminishing health-related fitness parameters such as body composition, cardiorespiratory and musculoskeletal strength, and motor skills. Students previously engaged in regular physical activity, notably school athletes, experienced significant fitness declines. This highlights the urgent need for targeted interventions to encourage active lifestyles among youth in the post-pandemic phase, aiming to avert long-term adverse health outcomes.Öğe The effects of adding Hibiscus sabdariffa L. flowers marmalade on some quality properties, mineral content and antioxidant activities of yogurt(Springer India, 2021) Arslaner, Ayla; Salik, Mehmet Ali; Bakirci, IhsanIn this study, the effect of Hibiscus sabdariffa L. flowers marmalade (HM) addition at different ratios (0%, 15%, 20%) was determined on the certain quality properties, total phenolic contents, antioxidant activity, mineral composition and heavy metal content of stirred-type yogurts (C, HM15, and HM20). The marmalade addition increased dry matter, ash, titratable acidity and viscosity whereas decreased pH, fat and protein values. HM addition significantly increased the antioxidant properties of yogurt samples. 2,2-Diphenylpicrylhydrazyl radical-scavenging activity, Copper (II) reducing antioxidant capacity and total phenolic content were found to be in the range of 5.92-26.73 mg TE/100 g, 4.88-15.03 mg TE/100 g, and 5.57-14.69 mg GAE/100 g, respectively. There were no statistically differences between control and HM-added groups in terms of lactic acid bacteria (LAB) counts, also in all samples the total LAB count was above 6 Log cfu/g during the storage. Fe, Mn, B, and Ba mineral values of samples with HM were higher than control sample. Cd, As, Hg and Li heavy metals were not detected in any of the samples, consequently results were within reliable limits reported by JECFA (Joint FAO/WHO Expert Committee on Food Additives) and Turkish Food Codex. As a result of the sensory evaluation, the samples containing 20% HM generally received higher scores than the samples containing 15% HM. Considering all the parameters, it was concluded that HM yogurts can be used as a different type in the functional yogurt industry due to its pleasant and characteristic taste.Öğe The effect of nurse-led motivational interviewing based on the trans-theoretical model on promoting physical activity in healthy older adults: A randomized controlled trial(Wiley, 2024) Sari, Ebru Sonmez; Kitis, YeterAimThe aim of this study was to evaluate the effect of motivational interviewing based on the trans-theoretical model promoting physical activity in older adults.MethodsA randomized controlled trial study was conducted with 117 older adults (intervention group: 58, and control group: 59) between April and November 2019. The data were collected via a questionnaire, trans-theoretical model scales, the Physical Activity Scale for the Elderly, the Katz Activities of Daily Living scale and a pedometer. The 24-week intervention consisted of regular motivational interviewing. The control group received usual care at the family health centre.ResultsFollowing the intervention, the Intervention Group showed significant improvements Exercise Processes of Change Scale, Exercise Self-Efficacy Scale and Perceived Benefits of the Decisional Balance Scale for Exercise. There was a significant difference between the groups in terms of stages of change. In the Intervention Group, 81.5% were in the contemplation stage in the pre-test, while in the post-test, 70.4% had transitioned to the action stage. In contrast, in the control group, 62.5% were in the contemplation stage initially, but in the post-test, only 9.3% had reached the action stage. The mean number of step counts increased significantly in favour of the Intervention Group, as did the Physical Activity Scale for the Elderly total score.ConclusionThe trial indicated that after the trans-theoretical model-based motivational interviewing, the stages of change among the older adults improved, as did their exercise behaviours. It is recommended that the trans-theoretical model and motivational interviewing be used by nurses to improve healthy lifestyle stage behaviours in older adults. What is already known about this topic? Physical immobility ranks fourth among the leading risk factors for mortality globally. Older adults constitute the age group which leads the most sedentary life in society and is most affected by physical inactivity. In Turkey, one out of every two people undertakes insufficient physical activity, and this rate increases with advancing age.What this paper adds? Nurse-led motivational interviewing based on the trans-theoretical model was effective in increasing the physical activity levels of the older adults.The implications of this paper: It is recommended that the trans-theoretical model and motivational interviewing should be used by nurses to improve healthy lifestyle behaviours in older adults. It is recommended that studies be conducted to assess the effectiveness of interventions aimed at promoting physical activity in older adults via both qualitative and quantitative methods.Öğe The effect of various industrial dust particles on the performance of photovoltaic panels in Turkey(Springer Heidelberg, 2023) Gungor, Okan; Kahveci, Hakan; Gokce, H. SuleymanThe accumulation of dust is one of the main causes of power loss in photovoltaic (PV) farms, and the effect of dust particles' size and chemistry on system performance is often overlooked. This study has focused on a comprehensive analysis of the effect of different dust particles collected from common industrial production facilities in Turkey on the performance of PV panels in the indoor laboratory environment. The collected dust samples were analyzed to determine the dust sample particles' chemical properties, size, character, and topography. The data for dust samples at different weights with changes in maximum power point (MPP) of PV panel has been collected using the artificial solar irradiation source system. Thus, the mathematical correlations (R-2 >= 0.965) between the PV panel Thevenin resistance (RTH), fill factor (FF), MPP, and pollution rate were obtained using these collected data and particle swarm optimization (PSO). According to the results of the obtained mathematical correlations, marble dust is 2.3, 3.4, and 4.2 times less polluting than cement, fly ash, and silica fume, respectively. Additionally, it was observed that smaller dust particles block more light than larger ones of the same weight and reduce MPP, FF while increasing the R-TH.Öğe The effect of guided imagery on postoperative pain and comfort of geriatric orthopaedic patients: a randomized controlled trial(Wiley, 2023) Ozdemir, Ahmet; Gunes, Huseyin; Saritas, SerdarBackgroundThe purpose of this study is to investigate the effects of guided imagery on postoperative pain and comfort in geriatric orthopedics patients. MethodsThis study was carried out with a randomized-controlled true experimental design. The population of the study included geriatric patients receiving treatment at the orthopedics and traumatology inpatient clinic of a university hospital. Based on random selection, the sample consisted of total of 102 patients, including 40 patients in the experimental group and 40 in the control group. The data were collected using a Personal Information Form, the Visual Analog Scale, and the General Comfort Questionnaire. ResultsAfter the guided imagery intervention, the pain levels of the experimental group significantly decreased compared to their baseline pain levels (t = 4.002, P = 0.00). Their perceived comfort was also significantly improved (t = -5.428, P = 0.00). Although the perceived comfort of the control group decreased, this decrease was not statistically significant (t = 0.698, P = 0.489). ConclusionIt is recommended that guided imagery, which is an inexpensive and accessible method, be integrated into the nursing care process to reduce the pain and increase the comfort of geriatric orthopedics patients.Öğe The effect of guided imagery applied on geriatric orthopaedic patients on preoperative anxiety and comfort(Wiley, 2023) Gunes, Huseyin; Saritas, Serdar; Ozdemir, Ahmet; Bulbul, Ali SavasBackground: This study was designed to examine the effect of guided imagery applied to geriatric orthopaedic patients on preoperative anxiety and comfort.Methods: This study was conducted as a randomized controlled trial. The population of the study consisted of geriatric patients treated in the orthopaedics and traumatology clinic of a university hospital. The sample consisted of 80 patients, including the experimental group (n = 40) and the control group (n = 40). Personal Descriptive Form, The State-Trait Anxiety Inventory (STAI) and General Comfort Scale were used as data collection tools.Results: After the guided imagery application, it was determined that the anxiety of the experimental group decreased statistically significantly, and their comfort improved (P < 0.05).Conclusion: After the imagery, it was determined that the patients in the experimental group had a decrease in their anxiety level and an improvement in their comfort. Since it is a low-cost and easily accessible method, applying imagery in the preoperative period is recommended.Öğe The effect of high-intensity plyometric training on anaerobic performance parameters: a pilot study in U17 elite A league(Peerj Inc, 2024) Soyler, Mehmet; Zileli, Raif; Cingoz, Yunus Emre; Kilincarslan, Gokmen; Kayantas, Idris; Altug, Tolga; Asan, SelimThe aim of this study was to examine the effects of high-intensity plyometric training (HIPT) on some parameters in elite soccer players in the U17. Volunteer soccer players were randomly divided into two groups according to their positions: the regular training (RT) group (age: 16.71 +/- 0.47 years; stature: 163.46 +/- 3.31 cm; body weight: 61.04 +/- 1.59 kg) and the HIPT group (age: 16.64 +/- 0.50 years; stature: 165.60 +/- 3.03 cm; body weight: 59.76 +/- 1.92 kg), and each group included five defenders, five midfielders, and four attackers. While the RT group did only routine soccer training, the HIPT group performed high-intensity plyometric training three days a week in addition to routine soccer training. In the study, body weight, stature, sprint (10 m, 30 m, and 40 m), jump (standing long jump, right and left-limb triple hop) and 5-0-5 change of direction speed test measurements of the soccer players were taken. Skewness and Kurtosis values obtained from the pre-test and post-test measurements were calculated to test whether the normality assumption of the study was met. A mixed measure two-way ANOVA test was used to determine the difference between the pre-test and post-test. The significance was set asp < 0.05. The results indicated that 8-week high-intensity plyometric training provided more improvement in measured performance parameters than routine soccer training. As a result, when the data obtained is examined, it can be said that HIPT had better values in sprint, jump, and change of direction parameters, so plyometric training was more beneficial for anaerobic parameters than routine soccer training in children. It is recommended that the trainers make their plans considering these results.
