Nursing care based on the Support-Based Spiritual Care Model increases hope among women with breast cancer in Iran.

PURPOSE: Taking care of cancer patients and treating them are among major challenges in the field of health. Several studies have shown that promotion of hope is an efficient strategy for effectively treating this group of patients, reducing their symptoms, and improving the quality of their life. It seems that spiritual care can boost hope in these patients. This study aims to determine the effects of nursing care based on the Support-Based Spiritual Care Model on boosting hope among women with breast cancer. METHODS: In this controlled clinical trial, 72 patients with breast cancer were selected through consecutive sampling and randomly assigned to two control and intervention groups (n = 36 in each group) based on four randomized blocks. The intervention was carried out based on the Support-Based Spiritual Care Model for the patients and their main caregivers in six sessions. Besides, the Snyder's hope scale was completed before and 1 month after the intervention by the participants in the intervention and control groups. RESULTS: The results of the independent samples t-test showed no significant difference in the mean scores of hope between the intervention and control groups before the intervention (P > 0.05). However, after the intervention, the mean scores of hope for the intervention and control groups were 46.71 ± 4.61 and 40.40 ± 5.42, respectively, showing a significant intergroup difference as verified by the independent samples t-test (P < 0.05). CONCLUSION: According to the results of this study, providing nursing care based on the Support-Based Spiritual Care Model can raise hope in patients with breast cancer. CLINICAL IMPLICATIONS: Healthcare professionals can boost hope in cancer patients through proper planning and adequate support in providing nursing care based on the proposed model.

SGHRP: Secure Greedy Highway Routing Protocol with authentication and increased privacy in vehicular ad hoc networks.

VANETs are networks of connected intelligent vehicles that can communicate with each other, as well as with infrastructure and fixed roadside equipment. As a result of the lack of fixed infrastructure and open-access environment, security is crucial when sending packets. Secure routing protocols have been proposed for VANETs, but most are focused on authenticating nodes and creating a secure route, without considering confidentiality after the route is created. Using a chain of source keys validated by a one-way function, we have proposed a secure routing protocol called Secure Greedy Highway Routing Protocol (GHRP), which provides increased confidentiality over other protocols. As part of the proposed protocol, the source, destination, and intermediate nodes are authenticated using a hashing chain in the first stage, and in the second stage, one-way hashing has been used to increase data security. In order to resist routing attacks such as black hole attacks, the proposed protocol is based on the GHRP routing protocol. The proposed protocol is simulated using the NS2 simulator, and its performance is compared with that of the SAODV protocol. Based on the simulation results, the proposed protocol performs better than the mentioned protocol in terms of packet delivery rate, overhead, and average end-to-end delay.
