Introduction: In some previous studies, vitamin B12 treatment showed immunomodulatory effects and restored the immunological abnormalities in patients with pernicious anemia (PA). In the present study, peripheral blood T cell subsets, including regulatory T cells (Tregs), were examined before and after vitamin B12 treatment in PA patients. Patients and Methods: The percentages of CD4, CD8, Th1, Th2 and Tregs were examined in 23 PA patients before vitamin B12 treatment, in 23 other PA patients after vitamin B12 treatment and in 28 healthy controls. Results: The mean percentage of CD8+ T cells was significantly higher in the control group (23.0%; 95% CI, 20.4-25.6%) than in the pre- (16.0%; 95% CI, 12.1-20.0%) and posttreatment groups (15.2%; 95% CI, 11.8-18.6%; p < 0.05). The CD4/CD8 ratio was significantly lower in the control group (2.01; 95% CI, 1.66-2.34) than in the pre- (3.45; 95% CI, 2.55-7.80) and posttreatment groups (2.97; 95% CI, 2.22-3.72; p < 0.05). There was no significant difference in the mean Th1/Th2 ratio among these groups. There were significant increases in the mean percentage of Tregs in the pre- (6.29%; 95% CI, 5.04-7.54%) and posttreatment groups (7.77%; 95% CI, 6.34-9.20%) compared with the control group (4.18%; 95% CI, 3.92-4.47%; p < 0.05). Conclusions: The percentage of Tregs was significantly higher in PA patients than in normal subjects, and this high Treg percentage was not different before and after vitamin B12 treatment. Other immunological alterations also did not recover after vitamin B12 treatment, so that these immunological changes appear to be the cause of PA and are not induced by vitamin B12 deficiency.

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.

Background: Caused by an imbalance in the body’s oxidant and antioxidant status, oxidative stress can give rise to tissue damage and exacerbation of many diseases. Objectives: This study investigated the oxidative stress markers in patients with fractures and healthy subjects. Methods: In a cross-sectional case-control study, 40 patients with fractures admitted to an orthopedic ward and 40 healthy, non-fractured patients were selected using convenience sampling. Serum was analyzed for oxidant and antioxidant activities based on standard methods. P < 0.05 was considered statistically significant. Results: There was a significant difference in mean TAC between the case (748.2 ± 302.83 μmol/L) and control (984.90 ± 207.02 μmol/L) groups (P = 0.003). The mean MDA was 16.61 ± 4.16 µmol/L in the case group and 18.45 ± 5.43 µmol/L in the control group (P = 0.09). The mean SOD was 63.41 ± 16.67 U/g Hb in the case group and 58.54 ± 21.83 U/g Hb in the control group (P = 0.2). There was no significant difference between the two groups in terms of BMI and other variables. Conclusions: A significant difference existed in TAC between the two groups, which indicated increased oxidative stress in patients. However, oxidative stress could occur before and after undergoing fractures. The results suggested a slight, but not significant, difference between the two groups in the SOD and MDA scores. More conclusive results are required to determine the enzymatic and non-enzymatic markers of oxidative stress in larger sample sizes and during different stages of treatment.

Abstract Background Good oral health (OH) is essential for physical, social, mental health, and overall quality of life. This study assessed the usefulness of the theory of planned behavior (TPB) in changing oral health-related behaviors among school children aged 11–13 years in Saveh, Iran. Methods In this descriptive before and after study, participants were sixth-grade students at single sex primary schools in Saveh city, Iran. We recruited 356 school children in 2019. Using simple random sampling, a male and a female school per district were allocated to the experimental group and the remaining schools to the control group. Our planned oral health education consisted of four one-hour training sessions over 1 week. The first session familiarized the participants with important information about OH. In the second session, we applied a brain storming exercise to identify the benefits and barriers to flossing and brushing. In the third session, a short film about correct brushing and dental flossing technique was shown and research team also used role-playing to correct any mistakes. In the final session students were taught about the importance and the application of OH planning and given forms to help plan for brushing. Results Participants for the study included 356 students (180 in the experimental group and 176 in the control group) who completed the post-test questionnaire. The mean age ± standard deviation was 11.55 years ±0.93 in the experimental group and 11.58 years ±1.01 in the control group. After the intervention, the paired t-test indicated a significant difference between the mean and standard deviation of the action plan and coping plan constructs in the experimental group before and after the intervention (p < 0.05). Covariance analysis indicated a significant difference between scores of intervention and control groups under statistical control of post-test in two groups (covariate) after a peer-led education program (post-test) (p < 0.05). Conclusion A shortage of professional health workers in education settings together with the ease, usefulness and low-cost of this peer-led method, suggest further steps should be taken to implement it more widely to improve and enhance primary school aged students’ oral health behavior.

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.

Abstract. In this study, children with vitamin B12 deficiency anemia (V-B12DA) and control subjects were evaluated for erythrocyte glutathione peroxidase, catalase and superoxide dismutase enzyme activities, glutathione, malondialdehyde, serum total sialic acid, total antioxidant status, cobalt, chromium, copper, selenium, vanadium, zinc, iron, lead, magnesium, calcium, sodium, potassium, chloride, phosphorus levels, and the associations of these variables were assessed. The study included 50 children with V-B12DA and 50 control subjects. It was found that the V-B12DA group was significantly lower than the control group, with regard to the mean±the standard error of the mean levels of cobalt (0.089±0.009; 0.058±0.0063 μmol/L, p<0.01), selenium (2.19±0.087; 1.88±0.057 μmol/L, p<0.01), vanadium (1.31±0.053; 1.18±0.035 μmol/L, p<0.05), magnesium (3.02±0.15; 2.73±0.068 μmol/L, p<0.05), zinc (50.76±1.96; 42.23± 1.53 μmol/L, p<0.001), and vitamin B12 (427.20±21.45; 157.08±3.96 pg/mL, p<0.001). Moreover, a significant elevation in total sialic acid (1.44±0.050; 1.61±0.043 mmol/L, p<0.01), and mean corpuscular volume (MCV) (75.37±0.95; 79.91±1.14 fL, p<0.01). It was observed that in the V-B12DA, significantly linear correlations were observed between cobalt – vitamin B12 (r=0.334; p=0.025), vanadium – MCV (r=0.315; p=0.017), vitamin B12 – MCV (r=−0.297; p=0.026). The findings of the study indicated that the levels of cobalt, vanadium significantly associated with traditional vitamin B12-deficiency parameters. Vitamin B12 and MCV should be measured together with cobalt, vanadium for monitoring the vitamin B12 deficiency anemia.

AbstractBackgroundThe vital signs reflect the physiological state of patients in various clinical conditions. The purpose of this study was to compare the effects of cold compress and Xyla-P cream on hemodynamical changes during venipuncture in hemodialysis patients.Methods and MaterialIn this clinical trial study, 50 patients under hemodialysis were selected by simple random sampling. The patients were then randomly assigned to either Xyla-P cream, cold compress or placebo groups. The vital signs (blood pressure and pulse) were measured upon two intermittent hemodialysis sessions before and after venipuncture. Data were analyzed using repeated measures analysis of variance.ResultsThe mean alternation in systolic blood pressure was significantly different comparing the placebo and cold compress groups before and after intervention (p<0.001). However, the difference was not significant between the Xyla-P cream group and either placebo (p=0.402) or ice compress (p=0.698) groups. The difference of the mean diastolic blood pressure was significant comparing the placebo group with either the Xyla-P cream group (p=0.003) or cold compress group (p<0.001) before and after intervention. In addition, there was a significant difference in the mean number of heartbeats comparing the control group with either the Xyla-P cream group (p<0.001) or cold compress group (p<0.001) before and after the intervention.ConclusionsConsidering the beneficial effects of ice compress and the Xyla-P cream on reduction of cardiovascular parameters, it is recommended to use these methods in hemodialysis patients during venipuncture.

Homocysteine metabolism is increasingly implicated in a diverse group of clinical disorders, including atheromatous vascular disease. We studied the disposition of homocysteine via the trans-sulphuration pathway, plasma glutathione peroxidase (GPx) activity and plasma levels of the sulphated hormone dehydro-epiandrosterone sulphate (DHEAS) in six vitamin B12-deficient human subjects before and after 2 weeks of vitamin B12 repletion, both in the fasting state and following an oral methionine load (0.1 g/kg body weight). Fasting plasma total homocysteine concentrations fell (P = 0.03) and total cysteine concentrations rose significantly (P = 0.048) after treatment for 2 weeks with vitamin B12 injections. The magnitude of the mean fall in the fasting concentration of homocysteine (38.8 µmol/l) was similar to the mean rise in cysteine levels (36.0 µmol/l) following vitamin B12 therapy. Circulating levels of homocysteine were increased at 4 h after a methionine load when compared with fasting levels, both before and after vitamin B12 repletion (P = 0.003 for both). Total cysteinyl-glycine was lower post-methionine than in the fasting state following vitamin B12 therapy (P = 0.007). Fasting plasma GPx fell significantly after 2 weeks of vitamin B12 therapy (P = 0.05). The change in plasma GPx between the fasting state and 4 h after methionine loading was significantly different pre- and post-vitamin B12 therapy (P = 0.05). The present study provides indirect support to the hypothesis that defects in the trans-sulphuration and remethylation of homocysteine produce hyperhomocysteinaemia in vitamin B12 deficiency in human subjects. Elevated homocysteine levels directly or indirectly may up-regulate GPx. Sulphation status, as measured by plasma DHEAS, was unchanged.

Abstract 1. A relationship has been observed between the serum and erythrocyte folate in normal subjects. 2. Patients with folate deficiency were more readily differentiated from normal subjects by determinations of serum folate activity than by determinations of erythrocyte folate activity. 3. In pernicious anemia in relapse, accumulation of serum folate and/or depletion of erythrocyte folate was observed in all patients, resulting in a disturbance of the normal relationship between the serum and erythrocyte folate activity. This altered relationship was corrected following the reticulocytosis induced by vitamin B12 therapy. 4. Patients receiving amethopterin therapy appear to incorporate the folate antagonist into maturing erythroid cells, since the erythroid cells so formed showed anti-bacterial activity for several weeks following the administration of the antagonist. 5. Preliminary fractionation of folate co-enzymes in erythroid cells of a patient with pernicious anemia before and after therapy revealed no significant difference in the distribution of the co-enzymes induced by therapy. A significant proportion of the folate activity of the erythroid cells was found in a fraction eluted from the DEAE column by sodium hydroxide. 6. The data presented are consistent with a direct effect of vitamin B12 on folate transport into the erythroblast.

Pain Symptoms

Background; Both herpetic pain and itching in shingles are two symptoms whose pathogenesis has not been elucidated, although they are thought to be due to nerve damage. These two symptoms are difficult to treat and negative impact quality of life. In addition, It is unclear which patient will have the symptoms of itching or pain. Vitamin B 12 is a neurotropic agent which is contributes to the treatment of nerve damage, and effective in treating neuropathic pain and itch. In this study we investigated that is relationship between vitamin B12 both herpetic pain and herpetic itch. Methods; In this study, we investigated the effect of vitamin B12 values on itching and pain symptoms that patients with shingles have in the acute period. Vitamin B 12 values of 53 adults with patients with shingles with herpetic pain or herpetic itching were recorded and compared with the control group. Results; We found that patients with herpetic pain had lower vitamin B12 values than the control group (p=0.046) and patients with herpetic itch (p=0.021). Vitamin B12 values of herpetic itch patients did not show significant difference from the control group (p=0.816). Conclusions; Although vitamin B12 deficiency plays a role in the etiology of herpetic pain, it has no effect on herpetic itching. Our study supports that the etiopathogenesis of HI is different from herpetic pain, and will help studies focusing on herpetic itching etiopathogenesis.
