The effect of virtual rainforest and a white noise mobile application on satisfaction, tolerance, comfort, and vital signs during arthroscopy.

BACKGROUND AND PURPOSE: This study was conducted to investigate the effect of Virtual Rainforest (VRF) and a White Noise (WN) mobile applications on patient satisfaction, tolerance, comfort, and vital signs during arthroscopic knee surgery. METHODS: This is a randomized, controlled, interventional study. The study was completed with a total of 93 participants, 31 in the VRF group, 31 in the WN group, and 31 in the control group. Data were collected using a Patient Information Form and a Visual Analog Scale for satisfaction, tolerance, and comfort. RESULTS: The results of study showed that there were significant increases in tolerance, satisfaction, comfort, respiratory rate, and oxygen saturation levels and significant decreases in heart rate, systolic and diastolic blood pressures in both VRF and WN groups (p < .05). In the control group, no significant difference was found between the means of the variables before and after the procedure (p > .05). CONCLUSION: According to the results of the study, VRF and WN applied during the arthroscopy procedure increased satisfaction, tolerance, and comfort in patients and had a positive effect on 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.

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.
