The Effect of Virtual Reality Glasses and Stress Balls on Pain and Vital Findings During Transrectal Prostate Biopsy: A Randomized Controlled Trial.

PURPOSE: This study aimed to determine effect of virtual reality (VR) glasses and stress balls (SB) on patients' pain and vital signs during transrectal prostate biopsy. DESIGN: This experimental research was conducted using a pre or post-procedure randomized controlled model. METHODS: The study population consisted of 96 male patients who were admitted to the TRUS Unit of the Urology Department of a state hospital in southeastern Turkey for prostate biopsy. The patients were divided into three groups by block randomization as 32 for VR, 32 for SB, and 32 for the control group. A Patient Information Form and the Visual Analogue Scale were used to collect data. In data analysis, number, percentage, mean, standard deviation, chi-square, dependent group t-test, and ANOVA tests were used. RESULTS: Comparing mean values of pain and vital signs between the groups, there was no statistically significant difference in terms of pre-test mean scores (P > .05). After Tukey advanced analysis, we found that VR and SB significantly decreased pain, diastolic blood pressure, pulse, and respiratory rate and significantly increased oxygen saturation (P < .05). CONCLUSIONS: We found that VR glasses and squeezing SBs during the transrectal prostate biopsy procedure reduced pain and positively affected vital signs.

A comparative study on biological activities of different solvent extracts from whole seed, seed coat and cotyledon of two Lathyrus species

Abstract The present study was conducted to assess the phenolic content, and antibacterial and antioxidant activities of Lathyrus L. species. The extraction of phenolic compounds from whole seeds, seed coat and cotyledon of Lathyrus hierosolymitanus Boiss. and Lathyrus annuus L. seeds was performed employing different solvents. Total phenolic content (TPC) was measured by Folin- Ciocalteau assay, while the antioxidant activity was determined by DPPH radical scavenging activity, and reducing power assay. It was found that TPC of extracts ranged from 0.12 mg to 6.53 mg GAE/gdw. For each solvent, seed coat extracts were generally observed to render higher TPC and antioxidant activities. There was a correlation between TPC and antioxidant activity. In addition, all extracts were also examined for their antimicrobial activity against Bacillus cereus, Escherichia coli and Pseudomonas aeruginosa. Methanol extracts showed the highest antibacterial activity which is consistent with TPC, but there was no correlation between TPC and antibacterial activity. Solvents were observed to have effects on gallic acid, caffeic acid, and epicatechin extractions. HPLC analysis results of extracts confirmed methanol and ethanol as preferred solvents for phenolic extraction from Lathyrus sp. Phenolic content in the extracts could be suggested to contribute to their antioxidant and antibacterial activity.

Psychological Hardiness and Spirituality in Patients with Primary Brain Tumors: A Comparative Study.

The purpose of this research was to compare healthy individuals with patients having primary brain tumors (PBTs) with respect to their psychological hardiness and spirituality. In this study, a comparative and descriptive research design was employed. The research sample included 122 individuals: 61 patients with PBTs and 61 healthy individuals. When healthy individuals were compared with patients with PBTs, it was found that the patients with PBTs had significantly lower mean scores for spirituality and psychological hardiness. The study revealed that spirituality (ß = .661) and age (ß = - .270) were statistically significant predictors of psychological hardiness (p < .001). These variables explained 53% of the total variance. To decrease the negative effects of PBTs on psychological hardiness, nurses and other health staffs should focus on strategies that strengthen patients' spirituality.

Hope, Sociodemographic and Clinical Characteristics as Predictors of Stigma-Related Negative Discrimination Experiences of Patients With Primary Malignant Brain Tumor.

ABSTRACT: BACKGROUND: A brain tumor can cause specific dysfunctions including psychosocial problems, and neurological, cognitive, mental, personality, behavioral, body image, and self-concept changes. Hope is reported in previous studies as an important and protective factor during the difficult duration of the disease. The purpose of this study is to examine hope and related factors as predictors of the stigma-induced negative discrimination experience of patients with primary malignant brain tumor. METHODS: The relational research method was used. The study was conducted in neurosurgery and oncology clinics and outpatient clinics of a university hospital in Southeastern Turkey between July 2018 and March 2020. The research data were collected using an information form, the Discrimination and Stigma Scale, and the Dispositional Hope Scale. The research sample consisted of 124 patients with primary malignant brain tumor. The data were analyzed by stepwise multiple linear regression analysis. RESULTS: The average age of the patients with primary malignant brain tumor was 46.64 (±12.00) years. Of all the patients, 61.3% were male, and 25% received radiotherapy. When the negative discrimination experience of patients with primary malignant brain tumor was examined, age (ß = -0.244, P = .004), total dispositional hope (ß = -0.225, P = .009), and currently receiving radiotherapy (ß = 0.169, P = .048) were determined to be significant predictors. CONCLUSION: This study demonstrates the importance of hope, age, and treatment type in the negative discrimination experience of patients with primary malignant brain tumor. Initiatives taking hope into account should be planned by nurses and healthcare professionals to reduce patients' experience of negative discrimination.

The effects of watching comedy videos on anxiety and vital signs in surgical oncology patients.

BACKGROUND: Cancer, a disease as old as recorded human history, causes patients pain and psychological problems. Watching comedy videos can distract these patients, relieving psychological issues without causing any further harm. METHODS: This randomized clinical trial was conducted on patients who were candidates for oncologic surgery at a university hospital in Turkey. The sample of the study consisted of 88 patients. Before surgery, patients in the experimental group (n = 44) watched comedy videos while those in the control group (n = 44) received no intervention. The Patient Introduction and Registration Form and the State and Trait Anxiety Inventory (STAI) were used as data collection tools. Anxiety, measured by the STAI, and vital signs (blood pressure, pulse, respiration, and oxygen saturation) were measured before and after the experimental protocol. Descriptive statistics, chi-square and t-test were used in the analysis of the data. RESULTS: The pretest of STAI scores and vital signs were similar in both groups (p  >  0.05). After video watching, the mean state anxiety score of the patients was 43.36 ± 9.76 in the experimental group and 47.13 ± 5.76 in the control group. The difference between the mean anxiety scores of the two groups was statistically significant (p < 0.05). However, there were no significant differences in vital signs across groups (p > 0.05). Within group pre- versus post-treatment comparisons showed significant reduction in anxiety, diastolic and systolic blood pressures in the video group (p<0.05), while in controls, there was no significant improvement in anxiety and physiologic values. CONCLUSIONS: The results suggest that watching comedy videos has a beneficial effect on pre-operative anxiety and blood pressure in surgical oncology patients.

The effects of lavender oil on the anxiety and vital signs of benign prostatic hyperplasia patients in preoperative period.

BACKGROUND: This study was conducted to determine the effects of lavender oil on the levels of anxiety and vital signs in benign prostate hyperplasia patients (BPH) in their preoperative period. METHOD: This was a quasi-experimental study and a pretest-posttest design with a control group. The population of the study consisted of elderly male patients who were hospitalized at the urology clinic of a hospital in Turkey, eligible for inclusion, and who were scheduled to undergo BPH surgery. These patients had a prostate mass >30 g on which medical treatment and minimal surgical treatment had not been succesful but which could be cured through open prostatectomy surgery and transurethral resection of the prostate. The sample consisted of 110 patients selected by the convenience sampling method and determined based on power analysis. RESULTS: According to data analysis, both groups showed significantly reduced anxiety after the smelling lavender oil. However, the experimental group reported a significantly higher decrease in anxiety [mean change: -38.47 (SD 8.68) vs -2.78 (SD 3.27)] in comparison to the control group (p < 0.001). The posttest mean vital signs of the groups were compared and there was a statistically significant decrease in respiration and increase in oxygen saturation (p < 0.05). CONCLUSION: The findings showed that lavender oil inhalation reduced anxiety levels and had effects on the vital signs of BPH patients in their preoperative period.

The Effect of Comedy Films on Postoperative Pain and Anxiety in Surgical Oncology Patients.

OBJECTIVES: To determine the effect of watching Turkish comedy films on postoperative pain and anxiety in oncology surgical patients. DESIGN: This study was conducted using a pre- and post-test randomized controlled trial model. MATERIALS AND METHODS: The study was conducted in a general surgery clinic of a hospital in eastern Turkey between January 2016 and January 2017. The sample of the study consisted of 88 patients (44 test, 44 control) selected by using the randomized sampling method. In the experimental group, funny videos from Turkish old comedy movies were watched for 10 min before surgery. Anxiety, measured by the State-Trait Anxiety Inventory, and vital signs were measured before and after the experimental protocol. In the analysis of the data, descriptive statistics, χ2 and t test were used. RESULTS: The state-trait anxiety pre- and post-test mean score of the experimental group was found to be 39.59 ± 3.66 and 37.54 ± 3.52 before and after watching the video, respectively, indicating a statistically significant difference between these two values (p ≤ 0.05). No statistically significant difference was found between the pre- and post-test state-trait anxiety scores of the patients in the control group. The decrease from the pre- to post-test mean pain score was determined as 0.65 ± 1.05 in the experimental group and 0.11 ± 0.96 in the control group. A statistically significant difference was found between the groups' post-test mean pain scores (p ≤ 0.05). CONCLUSION: The study results suggest that watching Turkish comedy movie videos has a positive effect on postoperative pain and anxiety in surgical oncology patients.
