ABSTRACT Plasma levels of testosterone (T) and 5α-dihydrotestosterone (DHT) were determined by radioimmunoassay in 29 patients with benign prostatic hypertrophy (BPH) and in 56 control men of various ages. No significant difference was found in T, DHT nor DHT/T ratio between BPH and control subjects of similar age. Plasma DHT was higher in the prostatic than in the peripheral veins in 8/9 patients with BPH during laparotomy, indicating a prostatic secretion of DHT. No difference in the mean T nor the mean DHT was found in peripheral plasma before and after adenomectomy.

Abstract Purpose: In our study, we aimed to determine the frequency of thyroid nodules in patients with acromegaly according to the American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) classification and its relationship with acromegaly disease activity. Methods: A total of 56 patients with acromegaly and age, sex, and body mass index matched with 56 healthy control subjects were included in our study. Thyroid-stimulating hormone, free thyroxine, and anti-thyroperoxidase antibody levels of patients and control subjects were measured. In addition, patients and healthy controls were evaluated by ultrasonography to determine thyroid structure, thyroid volume, and thyroid nodules and to make ACR TI-RADS classification. Results: Thyroid nodules were present in 31 (55.4%) of 56 patients in the acromegaly group and 20 (35.7%) of 56 subjects in the control group, and the frequency of thyroid nodules was significantly higher in the acromegaly group (p=0.038). The mean number of nodules in the acromegaly group and control group was 1.27±1.43 and 0.48±0.73, respectively, and the mean number of nodules was significantly higher in the acromegaly group (p=0.003). The number of patients with TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules in the acromegaly group was higher than the control group (p=0.026, p=0.049, p=0.007, respectively). No difference was found in terms of cytological findings between those who have undergone FNAB in the acromegaly group and control group. Conclusion: In our study, we found that the frequency of thyroid nodules, the number of thyroid nodules, and the number of TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules increased in patients with acromegaly. There was no significant difference between acromegaly disease activity and thyroid nodule frequency, number of thyroid nodules, and TI-RADS classifications.

Objective: Findings suggest dissatisfaction of half of the cancer patients regarding pain and anxiety management. This study aimed to determine the effect of reflexology on the intensity of pain and anxiety among patients with metastatic cancer hospitalized inadulthematology ward.  Methods: In this study, the samples were selected from adult hematology ward in Baghaei 2 hospital in Ahwaz, Iran, according to the inclusion criteria. They were then assigned into treatment and control groups. In the treatment group, reflexology protocol was performed following manual reflexology method by Fr Josef Eugster based on Ingham method on the patient’s bed. In the control group, sole touching was used as the placebo. Reflexology was performed for three days, 30 min per day. Spielberger questionnaire were provided to the samples and completed in the first and third days, and Spielberger questionnaire was provided to the samples and completed. The data obtained from this study were then analyzed by SPSS 20.Results: The two groups did not show a significant difference in terms of demographic characteristics (p>0.05). Based on the obtained results, it was found that in the test group, there was a significant difference between the mean intensity of pain before and after the treatment across all 3 days as well as the mean anxiety of the 1st and 3rd days (p<0.05). However, in the control group, there was no significant difference in terms of mean pain intensity before and after the treatment across 3 days (p>0.05). No significant difference was observed between the mean anxiety of the 1st and 3rd days either (p>0.05).Conclusion: Considering the findings of this research, it can be concluded that reflexology has a positive effect on mitigating the intensity of pain and anxiety in metastatic cancer patients. Therefore, it is recommended that nurses employed in cancer centers benefit from the findings of this research to further help patients with cancer. It is also suggested that further research be conducted on the effect of reflexology on the pain and anxiety of other patients.

Abstract Background The knowledge and attitude of health care providers are important and influential factors in providing care services to the elderly and need to be considered during the training course. Simulation in geriatric nursing education can be an opportunity for learners to experience the restrictions of the elderly. The present study was conducted to determine the effect of training through simulation on the attitude and knowledge of nursing students in elderly care. Methods This study was quasi-experimental with two experimental and control groups of pre and post-test, which was conducted on 70 nursing students of the 5th semester (two groups of 35 people). For the experimental group, the elderly simulation suit was worn for two hours, which was designed by the researcher and created sensory, physical, and motor restrictions similar to the elderly for students. Before and after the study, Kogan’s attitudes toward older people scale and Palmore’s “facts on aging quiz” were completed by students. The data were analyzed using an independent t-test and paired t-test using SPSS version 16 software. Results The mean scores of students’ knowledge in the experimental and control groups had no significant difference at the beginning of the study (p < 0.05). But the mean scores of knowledge in the experimental group before and after the intervention was (9.2 ± 2.6) and (15.3 ± 3.5), respectively, and in the control group before and after the intervention was (10.4 ± 2.9) and (11.3 ± 2.6), respectively, which had a statistically significant difference (p = 0.0001). The mean scores of students’ attitudes in the experimental and control groups had no significant difference at the beginning of the study (p < 0.05). The mean scores of attitude in the experimental group before and after the intervention was (114.69 ± 8.4) and (157.31 ± 10.7), respectively and in the control group before and after the intervention was (113.34 ± 13.6) and (108.5 ± 16.6), respectively, which was significantly different (p = 0.0001). Conclusions Based on the findings, the experience of aging restrictions through simulation has improved the knowledge and attitude of nursing students towards the elderly. Nursing education requires the growth of attitudinal skills, individuals’ beliefs, and creating empathy among them, so creating simulation opportunities can assist nursing students in the educational processes.

Objective: Assessment and management of pain in patients under artificial respiration and hospitalized in Intensive Care Units (ICUs) are difficult, and is less considered by physicians and nurses. This study aims to determine the effect of classical music on physiological characteristics, and observational and behavioral measures of pain in unconscious patients admitted to ICUs. Methods: This is a quasi-experimental study conducted in 2019 on 30 unconscious patients admitted to ICU of Shohadaye Haft-e-Tir Hospital in Tehran, Iran, who were selected using a convenience sampling method, and divided into two groups of intervention and control. After obtaining a written informed consent from patients to participate, they completed a demographic/physiological form, Critical Care Pain Observation Tool (COPT) and Behavioral Pain Scale (BPC). Collected data were analyzed in SPSS V. 22 software by using descriptive and inferential statistics. Results: The Mean±SD age of patients in the intervention and control groups was 40.33±14.01 and 46±15.70 years, respectively. Comparison of physiological characteristics before and after the intervention showed no statistically significant difference in any groups except in Glasgow Coma Scale score (P<0.05). The mean pretest and posttest COPT scores in the intervention group were 3.73±0.94 and 1.96±1.32, respectively, and their mean pretest and posttest BPC scores were 5.94±1.39 and 4.22±1.08, respectively. Comparing the mean COPT and BPC scores before and after music therapy showed a statistically significant difference in the intervention group (P<0.05). Conclusion: It seems that classical music can reduce observational and behavioral measures of pain in unconscious patients hospitalized in ICUs. More studies are recommended for examining the effect of classical music on physiological characteristics of these patients.

Background. One of the most common surgical complications is nausea. Regarding the contradictory findings on the effect of aromatherapy with peppermint on the severity of nausea, in the present study, we aimed at comparing the effect of aromatherapy with 10% and 30% peppermint essential oils on the severity of nausea in surgical patients. Methods. This single-blind randomized controlled trial was conducted at the surgical ward of Imam Reza Hospital in Kermanshah, Iran. A total of 120 patients undergoing abdominal surgery were randomly divided into three groups of 10% peppermint, 30% peppermint, and control (40 patients in each group) using a random number table. In each of the intervention groups, 0.2 ml of 10% and 30% peppermint essential oil was inhaled. In the control group, the same amount of distilled water colored with green food coloring was inhaled. The severity of nausea was measured by nausea visual analog scale (NVAS) before and 10 minutes after the intervention. Results. In the 10% peppermint group, the mean severity of nausea before the intervention was 52.3 ± 13.7 out of 100, which reduced to 40.5 ± 13.5 after the intervention (p<0.001). In the 30% peppermint group, the mean severity scores of nausea before and after the intervention were 60.2 ± 15.0 and 39.7 ± 12.4, respectively (p<0.001). In the control group, the mean severity scores of nausea before and after the intervention was not statistically significant. There was no significant difference between the two intervention groups in terms of the mean severity of nausea after the intervention. Conclusions. It can be concluded that 10% and 30% peppermint essential oils are equally effective on the severity of nausea.

AIM: To investigate the comparison of total antioxidant capacity in the serum of patients with pterygium and control subjects. METHODS: This case-control study was conducted on all persons referred to Ophthalmology Clinic of teaching Hospital of Vali-Asr (peace upon to him) with clinical symptoms of pterygium during the year 2016. The control group was selected among patients referred to the Ophthalmology Clinic of Vali-Asr (peace without pterygium) that the two groups were matched in terms of age, gender and place of residence. Sixty-six persons [31 people (47%) in patient group and 35 people (53%) in the control group] were enrolled by convenience sampling. Venous blood sample was taken from all patients after the sampling using ferric reducing antioxidant power (FRAP); FRAP- as a quick 10min measurement, the antioxidant power measurement of samples according to the conversion of ferric iron (Fe3+) to ferrous iron (Fe2+) was checked. The collected data ware entered to software SPSS 21 and were analyzed by chi-square and Mann-Whitney tests at the level of α =0.05. RESULTS: The mean of antioxidant capacity in patients was 842/55±161/46 μmol/L and antioxidant capacity in healthy controls was 856/77±209/41 μmol/L (P=0.8). In the comparison of mean serum antioxidant capacity in healthy individuals and in the serum of people with pterygium based on gender the results showed that the antioxidant capacity mean in male control subjects has been 894/05± 176/82 μmol/L and in females control 780/01±118/33 μmol/L that the observed difference have been reported statistically significant (P=0.008) but the other comparison according the gender between cases and control does not show any significant difference. CONCLUSION: The results of this study showed that the full level of serum antioxidant capacity in patients has been less than the mean of antioxidant capacity in control subjects; however, the observed difference has not been significant. The results of this study were consistent with basic results carried out on the damaging effects of oxidative stress in the pterygium pathogenesis. Recommending diet with minerals and vitamins containing antioxidants may be preventing the onset and progression of pterygium.

Background: The crisis caused by the child's illness and hospitalization affects all family members. Fear, worry, and anxiety are common issues of hospitalized children’s mothers. Betty Newman's system model plays a vital role in adapting to stress detection and control. Objectives: This study aimed to examine the effect of the behavioral systems model on the concerns of mothers of children admitted to the surgical ward. Methods: This quasi-experimental study was conducted on 60 mothers of children admitted to the surgical ward of the Mousavi Hospital, Gorgan, Iran, in 2020. The participants were selected using convenience sampling and then divided into test and control groups using non-probability sampling. According to Neuman's systems model, participants in the test group received nursing care in 3 - 4 sessions (each lasting 30 - 45 minutes). Participants in the control group received only routine ward care. Data were collected using the Parental Concern Scale and analyzed with IBM SPSS Statistics 21 software using statistical tests (analysis of covariance, unpaired samples t-test, and paired sample test). Results: The mean score of maternal concerns before the intervention was 42.6 ± 3.06 in the control group and 43.21 ± 2.27 in the test group. The results of the independent samples t-test did not show any significant difference between the groups in terms of maternal concerns (P = 0.11). The mean post-intervention maternal concern score was 37.6 ± 2.71 and 41.716 ± 2.55 in the test and control groups, showing a significant difference between the groups as indicated by the t-test results (P < 0.01). However, the paired t-test outcomes showed no difference in the mean maternal concern score in the control group before and after the intervention (P = 0.92). In contrast, there was a significant difference in the mean maternal concern score in the test group before and after the intervention (P < 0.01). Conclusions: Given the effectiveness of Betty Neuman’s systems model, it can be used as a low-cost, effective care method to reduce maternal stress as the model was developed for understanding clients’ and caregivers’ needs and reducing their stress.

1. Erythrocyte choline transport was studied in 10 haemodialysis patients immediately before and after a haemodialysis session and in 10 control subjects. Choline uptake was measured in erythrocytes from normal and uraemic patients after washing in vitro and subsequent incubation in autologous plasma. Amines present in uraemic plasma were examined for their effect on choline transport in normal erythrocytes. 2. NMR spectroscopy was used to measure choline, trimethylamine and dimethylamine in erythrocyte extracts from nine control subjects, 32 subjects with renal impairment and nine samples from haemodialysis patients. 3. The increased choline influx in uraemic erythrocytes is significantly decreased by prior haemodialysis (mean Vmax pre-dialysis 146±20 μmol h−1 I−1, postdialysis 113±13 μ/mol h–1 I−1 (P < 0.005). After in vitro washing there is a fall in Vmax, and no longer any significant difference between pre- and post-dialysis samples. There remains a significant difference in the erythrocyte choline Vmax between samples from patients with chronic renal failure and from normal subjects (P < 0.005). 4. Human plasma was found to contain factors capable of increasing choline uptake. Trimethylamine and dimethylamine were found to inhibit choline uptake. Trimethylamine and trimethylamine-N-oxide transstimulated choline efflux, but the major transport substrate present in erythrocyte extracts from all groups was choline, which was higher in those with renal impairment (71 ± 10 μmol/l) than in haemodialysis patients (47 ± 10 μmol/l) and control subjects with normal renal function (40 ± 9 μmol/l). 5. Our data suggest that erythrocyte choline transport is increased in uraemia as a consequence of increased transporter number or activity, rather than the presence of intracellular substrate.

Abstract Background The most basic responsibility of nurses that even precedes their therapeutic role is respect for professional ethics in providing clinical care. The present study was conducted to determine the effect of group reflection on the knowledge, attitude and performance of nurses in relation to ethical codes. Methods The present blinded, before-after, educational trial was conducted on 86 nurses working at a general hospital in the south of Iran who were randomly divided into a intervention (n = 44) and a control (n = 42) group. Data were collected before and after the intervention using three tools, including a knowledge test, an attitude rating scale and a performance questionnaire. In the intervention group, the intervention given consisted of four sessions of group reflection, and the control group received a single lecture on ethical codes. Results The mean changes in the nurses’ score of knowledge after the intervention compared to before differed significantly in both intervention and control groups (P < 0.001), but there was no significant difference between the two groups in terms of the mean changes in the score of knowledge (2.73 ± 3.45 in intervention group vs. 2.57 ± 3.36 in control group, P = 0.83). Although the mean score of attitude differed significantly between the intervention and control groups in the posttest (34.7 ± 8.44 in intervention group vs. 29.95 ± 9.09 in control group, P < 0.014), the two groups were not significantly different in terms of the mean changes in the score of attitude in relation to ethical codes before and after the intervention (P < 0.14). Moreover, the two groups were significantly different in terms of the mean changes in the scores of performance in the two stages (9.07 ± 16.84 in intervention group vs. 0.67 ± 20.01 in control group, P < 0.001). Conclusion Group reflection can improve the knowledge, attitude and performance of nurses in relation to ethical codes. Although lectures can help improve nurses’ knowledge and attitude in this area, they have no significant effects on their performance.
