Relationship Between Health Anxiety and Psychological Resilience Among Nursing Students and Predictors of Psychological Resilience in the Last Period of the COVID-19 Pandemic.

OBJECTIVE: The study aimed to determine health anxiety and psychological resilience and to investigate the relationship between health anxiety and psychological resilience among nursing students in the last period of the coronavirus disease (COVID-19) pandemic. METHODS: This cross-sectional and descriptive study was conducted with 507 students in Turkey. The questionnaires used in the study were a student nurse information form, the Health Anxiety Inventory, and the Resilience Scale for Adults. RESULTS: The mean age of the students was 20.70 ± 1.77 years. The health anxiety mean score was 36.19 ± 6.55, and the resilience scale mean score was 117.13 ± 16.00. There was a weak negative correlation between the students' psychological resilience and their health anxiety (r = -0.207, P < 0.001). CONCLUSION: Having an extended family and having good relationships with family and friends were the predictors of psychological resilience. Social support and psychological care services under a biopsychosocial model by the management of university or faculty should be implemented for university students in order to preserve their resilience and well-being, to cope with the pandemic.

Motives for Caffeine Consumption Questionnaire (MCCQ): validity and reliability of Turkish version.

OBJECTIVES: The aims of this study are to make the Turkish validity and reliability of the scale that explain why caffeine intake. Additionally, it is crucial to highlight that the adaptation of the scale involved a confirmatory factor analysis (CFA) to validate its structure and the need for this adaptation in the Turkish context. MATERIALS AND METHODS: The study was carried out with a total of 200 university students, comprised of 93.5% female and 6.5% male participants, with a mean age of 21.74 ± 6.15 years who were actively studying in the faculties of the universities who accepted to participate voluntarily in the study were included. The Turkish version of the Motives for Caffeine Consumption Questionnaire (MCCQ) scale and the MCCQ was used as the data collection tools. To evaluate the statistical analysis findings, the margin of error was taken as 5%. The entire application was carried out with the R-project software. CFA was used to test the adaptation of the MCCQ scale from English to Turkish. RESULTS: The alpha internal consistency coefficient for the whole scale was calculated as 0.959. Just like the original scale, the Turkish version shows a six-factor structure: habit, alertness, mood, social, taste, and symptom management. In MCCQ-TR, it showed a low level of positive correlation with Yale Food Addiction Scale (YFAS). For the final scale with 23 items and 6 sub-dimensions, it was determined that the fit indices were at an acceptable level, and the internal consistency was highly reliable for all sub-dimensions and the total scale. CONCLUSIONS: It has been determined that the Turkish version of the MCCQ is a valid and reliable measurement tool to operationalize the motives of caffeine consumption and to reveal possible differences in the motives regarding gender, age, and the type of caffeinated products consumed. The use of CFA in adapting the scale ensures the robustness of the structural validity in the Turkish context, making this adaptation a valuable contribution to the field.

Acetone extracts of Berberis vulgaris and Cornus mas L. induce apoptosis in MCF-7 breast cancer cells.

Background/aim: This study aimed to determine the proliferation and apoptotic effects of extracts from Cornus mas L. and Berberis vulgaris fruits on human breast cancer cells (MCF-7). Materials and methods: The Cornus mas L. and Berberis vulgaris fruits, which constitute the herbal material of the study, were turned into 80% acetone extract after washing. The total phenolic content in Berberis vulgaris fruit extracts was determined calorimetrically using Folin-Ciocalteu reagent. The spectrophotometric method was used to determine the total flavonoid amount of the extracts. In order to measure the antioxidant capacity of Cornus mas L. and Berberis vulgaris fruits and extracts, DPPH Radical Scavenging Power test and Cu (II) ion reducing antioxidant capacity method were applied. Cell viability rates were determined by the XTT method. Flow cytometric measurement was performed to examine the apoptotic role of the extracts in the cell by using the Annexin-V/7-AAD commercial kit. Results: According to the data, Berberis vulgaris fruit extract appeared more effective on MCF-7 breast cancer cells in both 24 and 48 hours of exposure. Analyses made to examine the phenolic component and antioxidant capacity properties of the fruits used in the study and the results we encountered when we exposed the cell were found to be compatible with each other. Annexin-V/7-AAD method showed that the apoptotic effects of the extracts in 48 hour exposures were more effective. Conclusion: It has been determined that Cornus mas L. and Berberis vulgaris fruits, which are rich in phenolic components with high flavonoid content and high antioxidant capacities, support the apoptosis of cancer cells.

The Acute Effects of Different Intensity Whole-Body Vibration Exposure on Muscle Tone and Strength of the Lower Legs, and Hamstring Flexibility: A Pilot Study.

CONTEXT: The research on the change in properties of the lower leg muscles by different intensity sinusoidal vertical whole-body vibration (SV-WBV) exposures has not yet been investigated. OBJECTIVE: The purpose of this study was to determine effect of a 20-minute different intensity SV-WBV application to the ankle plantar flexor and dorsiflexor muscles properties and hamstring flexibility. DESIGN: Prospective preintervention-postintervention design. SETTING: Physiotherapy department. PARTICIPANTS: A total of 50 recreationally active college-aged individuals with no history of a lower leg injury volunteered. INTERVENTIONS: The SV-WBV was applied throughout the session with an amplitude of 2 to 4 mm and a frequency of 25 Hz in moderate-intensity vibration group and 40 Hz in a vigorous-intensity vibration group. MAIN OUTCOME MEASURES: The gastrocnemius and tibialis anterior muscle tone was assessed with MyotonPRO, and the strength evaluation was made on the same lower leg muscles using hand-held dynamometer. The sit and reach test was used for the lower leg flexibility evaluation. RESULTS: The gastrocnemius muscle tone decreased on the right side (d = 0.643, P = .01) and increased on the left (d = 0.593, P = .04) when vigorous-intensity vibration was applied. Bilateral gastrocnemius muscle strength did not change in both groups (P > .05). Without differences between groups, bilateral tibialis anterior muscle strength increased in both groups (P < .01). Bilateral gastrocnemius and tibialis anterior muscle tone did not change in the moderate-intensity vibration group (P > .05). Flexibility increased in both groups (P < .01); however, there was no statistically significant difference between the groups (d = 0.169, P = .55). CONCLUSIONS: According to study results, if SV-WBV is to be used in hamstring flexibility or ankle dorsiflexor muscle strengthening, both vibration exposures should be preferred. Different vibration programs could be proposed to increase ankle plantar flexor muscle strength in the acute results. Vigorous-intensity vibration exposure is effective in altering ankle plantar flexor muscle tone, but it is important to be aware of the differences between the lower legs.

Treatment of primary pterygium.

PURPOSE: To compare preserved human amniotic membrane transplantation and conjunctival autografts for treatment of primary pterygium. METHODS: Thirty-seven eyes of 35 patients with primary pterygium underwent surgical excision. In group A, 25 eyes were treated with conjunctival autografts. In group B, 12 eyes were treated with preserved human amniotic membrane transplantation. These two groups were compared in terms of complications, recurrence, and final appearance, prospectively. RESULTS: We observed two cases of recurrence in group A and five cases of recurrence in group B. The onset of recurrence was about 5.5 months in both groups. We observed two eyes with Dellen ulcer and one case with a Tenon's cyst in the superior temporal quadrant in group A and one case of Dellen ulcer and granulation tissue of one eye in group B. CONCLUSIONS: We suggest that free conjunctival autografting is a more effective technique in primary pterygium in terms of lowering recurrences compared with the amniotic membrane transplantation technique.
