and purpose: This study aimed to investigate the effect of melatonin on sleep quality and cognitive function of individuals undergoing hemodialysis. In this randomized controlled clinical trial, 102 eligible individuals were assigned to two equal intervention and control groups. The intervention group received melatonin 3 mg tablets half an hour before going to bed for six weeks, while the control group was given a placebo with similar conditions. This study had 102 participants who were divided into intervention and control groups. The mean age of the participants was 58.30 (SD = 12.10). Among the participants, 54.90% were female. Moreover, 33.33% of the individuals received dialysis for four years or longer. After the intervention, the mean and standard deviation of the Pittsburgh Sleep Quality Index (PSQI) was 12.66 (SD = 3.09) in the intervention group and 18.86 (SD = 3.8) in the control group (P < 0.001). Moreover, the mean sleep quality index in the intervention group showed a statistically significant difference before and after the intervention (P < 0.001); the PSQI score declined from 20.21 to 12.66. Likewise, there was a statistically significant difference between the two groups after intervention in the mean Montreal Cognitive Assessment (MoCA) index (P = 0.002); it was 24.27 (SD = 3.42) in the intervention group and 22.15 (SD = 2.3) in the control group. The mean MoCA score in the intervention group showed a significant difference before and after the intervention (P < 0.001), increasing from 21.19 to 24.27. According to the study's findings, melatonin can improve individuals undergoing hemodialysis' cognitive function and sleep quality. • After the intervention, the mean and standard deviation of the Pittsburgh Sleep Quality Index was 12.66 (SD = 3.09) in the intervention group and 18.86 (SD = 3.8) in the control group (P < 0.001). • The mean sleep quality index in the intervention group showed a statistically significant difference before and after the intervention (P < 0.001); the PSQI score declined from 20.21 to 12.66. • There was a statistically significant difference between the two groups after intervention in the mean Montreal Cognitive Assessment index (P = 0.002); it was 24.27 (SD = 3.42) in the intervention group and 22.15 (SD = 2.3) in the control group. • The mean MoCA score in the intervention group showed a significant difference before and after the intervention (P < 0.001), increasing from 21.19 to 24.27. • Mmelatonin can improve individuals undergoing hemodialysis' cognitive function and sleep quality.

Aim: This study aimed to determine the effects of acupressure on the intestinal function of patients undergoing Coronary Artery Bypass Graft (CABG) surgery. Background: Studies indicated that cardiovascular patients are prone to constipation. Acupressure is one of the therapeutic and palliative approaches that can be used by doctors, nurses, and even patients themselves. Methods: The present three-group randomized clinical trial study was conducted on 90 patients undergoing CABG surgery. In the intervention group, 48 hours after surgery the patients received acupressure points LI4 and ST25 twice a day (10 am and 6 pm) for three sequential days. In the sham group, the patients received acupressure at a 1.5 cm distance from the LI4-ST25 points, and the patients in the control group received only the usual care. This research used a demographic and medical information questionnaire, Rome IV scale, Bristol stool scale, symptom registration checklist, and daily excretion assessment checklist. The intestinal function indices were completed 24 hours after surgery (before intervention), 48, 72, 96, and 120 hours after surgery. Results: All three intervention, sham, and control groups were without defecation in 24 hours (before intervention) and 48 hours after surgery. There was a significant difference between the three intervention, sham, and control groups in the number of stools after 72 hours, 96 hours, and 120 hours after the intervention (p<0.001). Also, a significant difference was observed among the three groups in terms of stool consistency 96 hours after the start of the intervention (p=0.032) and 120 hours after the start of the intervention (p<0.001). Conclusion: The results showed that patients had a significant improvement in the number of bowel movements and stool consistency in the intervention group. In acute conditions, acupressure on LI4-ST25 points can positively affect intestinal function when patients are hospitalized in the intensive care unit. [ABSTRACT FROM AUTHOR]

Background and Objectives: High workload, insufficient resources, and many stressors in the workplace have led to the imposition of physical and psychological pressures on nurses, which exposes them to Death Anxiety (DA). This systematic review aimed to assess the DA and factors associated with its in nurses during the COVID-19 pandemic. Material and Methods: An extensive search was conducted on Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database (SID) databases via keywords including "Death", "Death Anxiety", "Nurses", and "COVID-19", from December 2019 to November 10, 2021. Results: 818 nurses were enrolled in four papers. Nurses' mean age and work experiences were 31.21 (SD=5.43) and 7.60 (SD=6.73) years, respectively. The mean DA of nurses during the COVID-19 pandemic was 7.30 (SD=2.23). Also, 31.05% of nurses had a high DA level during the COVID-19 pandemic. Age, sex, work experience, working hours per week, childbearing, several patients needing end-of-life care, direct participation in resuscitation operations, patient death, depression, mental health status, and life satisfaction were influential factors in DA nurses during the COVID-19 pandemic. Conclusion: Thus, nursing policymakers should pay special attention to these factors related to nurses' health maintenance and promotion programs to increase the quality of nursing care for COVID-19 patients. Also, it is recommended that psychological and communication support be provided to nurses during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Introduction: Human immunodeficiency virus infection /acquired immunodeficiency syndrome has grown to be one of the world's most momentous pandemics. The present study aimed to explore the effects of stigma on people living with HIV/AIDS (PLWHA) and recommend coping strategies to reduce this phenomenon. Materials and Methods: Using a narrative literature review, the related articles were searched, retrieved, and selected from the databases of Noor Specialized Magazines (Noormags), Elmnet, Scientific Information Database of Academic Center for Education, Culture, and Research (SID), IranMedex, and Magiran via the keywords of "Stigma, Social Stigma, Labeling, Acquired Immunodeficiency Syndrome, AIDS, Human Immunodeficiency Virus, and HIV" in Persian and in the databases of PubMed and Scopus in English. The same procedure was further performed in Google Scholar in both languages. The inclusion criteria were the full-text articles in Persian and English and the exclusion criteria were no access to the full-text articles, while review articles were removed. Results: Considering the inclusion and exclusion criteria and excluding the duplicate studies, 16 articles were recruited in total for review purposes. The effects of stigma on PLWHA consisted of individual and social consequences. As well, the most appropriate coping strategies to reduce stigma were acknowledged as "providing psychosocial support for infected people", "raising awareness in the public and medical staff", "cultivating spirituality and a close relationship with God", "developing and implementing counseling strategies", and "establishing specialty clinics for PLWHA". Conclusion: Given the study findings, it can be suggested that policy-makers and community healthcare managers pay much more attention to the individual and social consequences of HIV/AIDS and make further efforts to increase awareness in the public and medical staffs, strengthen spirituality in PLWHA, and set up specialty clinics for such individuals to cope with stigma.

This descriptive correlational study was aimed at determining the relationship of hemodialysis shift with sleep quality and depression in 310 hemodialysis patients. Demographic and Clinical Questionnaires, the Pittsburgh sleep quality index, and Beck's Depression Inventory were used to ascertain the aforementioned relationship. Among the patients, 59.6% reported poor sleep quality and 44.8% reported experiencing depression. Results show that these conditions were significantly related to many factors. Although dialysis shift was not significantly related to sleep quality and depression, sleep quality was found significantly associated with age, female gender, illiteracy, unemployment, residence in rural areas, diabetes, addiction to sedatives, and phosphorus levels. A significant relationship was also found between depression and phosphorus levels. Logistic regression predicted age, gender, illiteracy, unemployment, residence in rural areas, and addiction to sedatives as factors for poor sleep quality. A body mass index (BMI) above 30, decreased urea, and increased phosphorus were predicted as factors for increased depression. [ABSTRACT FROM AUTHOR]
