The Association of Iron Intake and Hypertension, Does Iron Intake Decrease Blood Pressure?

Previous studies reported that iron may have an indispensable role in the risk of hypertension (HTN). However, the result of the studies on the relationship between iron and risk of HTN is inconsistent. This study aimed to assess the association between the association of dietary iron intake and HTN in the Iranian population. This case-control study was conducted on 4184 people aged 35 to 70, including 1239 people with HTN and 2945 people with normal blood pressure (BP) in Sabzevar, Iran. Dietary intake was assessed using a food frequency questionnaire (FFQ). The Nutritionist IV software was used in terms of the assessment of dietary intake of iron. An inverse association was found between iron intake and HTN (OR = 0.97, CI 95%: 0.94-0.99, P = 0.04). The association remained significant after adjustment for age, gender, smoking, drinking alcohol, calorie intake, and BMI (OR = 0.94, CI 95%: 0.89-0.98, P = 0.01). As a conclusion, iron intake was inversely associated with HTN. Further longitudinal studies on the effect of iron intake on BP are required to confirm this finding.

Does dietary intake of caffeine have an effect on transient global amnesia?

AIM

Amnesia is a cognitive disorder that may lead to memory loss. Caffeine is a psychoactive substance which have an effect on memory and cognitive functions. This study aimed to assess the association of transient global amnesia (TGA) with dietary intake of caffeine.

METHODS

This cross-sectional study was conducted on the Sabzevar Persian cohort data of 258 patients with TGA and 520 healthy individuals in Sabzevar, Iran. The Nutritional data were gathered in face-to-face interviews using a valid Food Frequency Questionnaire. Different models of logistic regression were used to determine the association between TGA and dietary caffeine intake after adjusting the confounders including age, sex, education, job, marital status, physical activity, BMI, and calorie intake.

RESULTS

There was no significant difference in terms of dietary calorie intake of (2279.5 ± 757.9 vs. 2365.5 ± 799.5, p = 0.19), protein (70.79 ± 25.27 vs. 72.94 ± 24.83, p = 0.31), fat (59.97 ± 23.79 vs. 60.13 ± 26.38, p = 0.93), carbohydrate (376 ± 134 vs. 393.1 ± 137.8, p = 0.14), and caffeine (196.4 ± 127.9 vs. 186.3 ± 128.5, p = 0.36) between the groups. No significant association was found between TGA and dietary intake of caffeine (OR: 0.99, 95% CI: 0.99-1.01, p = 0.36). The results did not change after adjusting the confounders.

CONCLUSIONS

No significant association was found between TGA and dietary intake of caffeine. Further prospective studies are required to confirm this finding.

Egg consumption and risk of cardiovascular disease: a PERSIAN cohort-based study

BACKGROUND

Cardiovascular diseases (CVDs) are one of the main causes of death worldwide. Data on the effect of eggs consumption on the risk of CVDs are still unreliable. Therefore, this study aimed to investigate the association between CVDs and the consumption of eggs.

METHODS

In this case-control study, the required data were extracted from the Prospective Epidemiologic Research Studies in Iran (PERSIAN) cohort in Sabzevar, Iran. A total of 4241 adults participated including 1535 patients with CVDs as the case group and 2706 healthy people as controls. Egg consumption was assessed using a valid food frequency questionnaire (FFQ).

RESULTS

A significant association was observed between eggs consumption and stroke after adjustment for physical activity, body mass index (BMI), smoking, systolic blood pressure (SBP), diastolic blood pressure (DBP), using alcohol, lipid profile, diabetes, and the intake of energy, lipid, protein, carbohydrate, and cholestrol (OR:1.007, 95% CI:1.001-1.013, P = 0.03). No association was found between egg consumption with hypertension, cardiac ischemia, and myocardial infarction.

CONCLUSIONS

There was a significant association between the consumption of eggs and stroke. However, more studies are needed to examine the effect of eggs on CVDs.

Effects of chocolate on cognitive function in healthy adults: A systematic review and meta-analysis on clinical trials

Cognitive function is defined as performance in objective tasks that need conscious mind effort. It has been shown that consuming foods rich in flavanols causes neurobiological effects and improves learning, memory, and global cognitive function. This study aimed to investigate the impact of chronic chocolate consumption on cognitive function in healthy adults based on published trials. The PICO strategy was applied to examine the research question in this study. Researchers searched the Web of Science, Science Direct, Pubmed, Scopus, Cochrane Library, and Google Scholar databases. Related articles of randomized controlled trials that evaluated the chronic effect of chocolate on cognitive function were selected (all published from their inception to February 2021). The difference in means of the last and first measurements was the main effect measure between the control and intervention groups. For quantitative data synthesis, weighted mean difference (WMD) and 95% confidence interval (CI) were performed in the random effect model. Of the initial 340 articles identified, seven trials met the eligibility criteria. Chronic chocolate intake significantly reduced executive function time (WMD: -11.77, 95% CI: -22.49, -1.05, p = 0.03) of the participants. Further, the language and executive function (WMD: 6.38, 95% CI: 5.97, 6.80, p < 0.001) was raised by 6.38 times after the intervention with chocolate. We could not perform subgroup analysis due to insufficient trials and significant heterogeneity in some studies. It is concluded that daily consumption of cocoa may provide short and middle-term effects on young adults and make them better cognitive performance in learning, memory, and attention.

Synbiotic supplement for treatment of iron deficiency anaemia in haemodialysis patients: A randomized controlled trial

BACKGROUND

There is evidence that probiotics can increase the availability of iron. The aim of current study was to determine the effects of synbiotic supplementation on the haematological parameters and anaemia in haemodialysis patients.

METHODS

This study was a randomized, double-blind, placebo-controlled trial. Fifty patients were randomly selected from the haemodialysis section of Vaseii Hospital, Sabzevar, Iran. Subjects in the symbiotic and control groups received 2 capsules of synbiotic supplement or placebo, respectively, once a day for 8 weeks. Blood samples were divided into two test tubes in equal volumes. Blood haemoglobin, haematocrit, transferrin saturation, red blood cells (RBCs), and total iron binding capacity (TIBC) were measured with auto-analyser. Ferritin was determined using Sandwich enzyme-linked immunosorbent assay (ELISA).

RESULTS

Twenty tree patients in each group completed the study. Significant results were recorded in synbiotic groups regarding the concentration of blood haemoglobin, haematocrit, transferrin saturation, the number of RBCs, and serum ferritin compare to placebo group (P < .05). At the end of week 8, TIBC significantly decreased in synbiotic than placebo group (P < .05).

CONCLUSION

Synbiotic supplementation could be a safe and promising candidate in improving anaemia in CKD patients.

The Effects of an Educational Intervention Based on Poetry, Game, and Problem-Solving Skills on Promoting Nutritional Knowledge and Behavior in Iranian Primary School Students

Background: Current educational techniques may have a few effects on dietary habits and food preferences in adolescents, so by designing an educational attractive program, nutritional knowledge can be significantly enhanced. This study aims to investigate the effect of a structured educational intervention based on poetry, game, and problem-solving skills on promoting nutritional knowledge, and behavior in primary school students. Methods: This experimental study was conducted on 120 primary school students aged 10-12 years in Sabzevar, Iran, in 2019. The participants were selected through multi-stage random sampling and divided into experimental (EG, n=60) and control (CG, n=60) groups. The data collection tool was a researcher-made questionnaire consisting of three sections (demographic characteristics, nutritional knowledge section, and nutritional behavior section). The validity and reliability of the questionnaire were checked and confirmed. The educational program, including educational poems, a "road to health" game, and problem-solving skills, was designed. The EG received a self-directed educational program. Both groups completed the questionnaires before and one month after the intervention. Results: After the intervention, the mean scores of nutritional knowledge and nutritional behaviors significantly improved in the EG compared to the CG (P < 0.05). Moreover, after the intervention, the mean score of nutritional behavior in the EG significantly improved compared to before the intervention (P < 0.05). The highest percentage in mean scores in the food pyramid groups was related to the consumption of vegetables (27%), consumption of milk and dairy products (26%), non-consumption of low-value snacks (13%), and non-consumption of sugar and candy (11%), respectively. Conclusion: The educational program based on poetry, game, and problem-solving skills can be practical, attractive, and cost-effective for promoting nutritional knowledge and behavior in adolescents.

Using Local Nigella Sativa Oil to Relief Premenstrual Syndrome Symptoms

Background: Premenstrual Syndrome (PMS) is a common problem in women. Nigella sativa has been suggested for its anti-inflammation and analgesic effects. This study was conducted to evaluate the effect of Nigella sativa oil on PMS. Methods: This double-blind clinical trial was conducted on 124 female students within the age range of 18-25 years living in the dormitories of Sabzevar University of Medical Sciences. Participants were randomly divided into two groups. The intervention group (IG) rubbed 1-2 drops of Nigella sativa oil on their fontanels at night for sev­en days before their three menstrual cycles. The placebo group (PG) rubbed placebo in the same way. After three cycles, pain severity was measured by the visual analog scale. Data analysis was carried out using the Mann-Whitney U test and analysis of covariance. Results: The mean age of participants, the mean age of menarche, and the mean age of PMS onset were 20.55 ± 0.2, 13.52 ± 0.15, and 15.35 ± 0.3 years old, respectively. The results showed that Nigella sativa oil reduced the severity of all PMS symptoms except in terms of depression and abdominal bloating in IG compare to the PG. Conclusion: Nigella sativa oil in women with premenstrual syndrome can be a promising, safe, and easily available analgesic supplement.

Dietary pattern and telomere length in preschool children in a middle-income country

Telomere length (TL) has been associated with lifestyle and dietary pattern. However, the available evidence on this association in children is scarce, especially in low- and middle-income countries (LMICs). Therefore, this study aimed to evaluate the association of dietary pattern and leukocyte TL (LTL) in preschool children, Sabzevar, Iran (2017). This cross-sectional study was based on 187 preschool children (aged 5 to 7) recruited from 27 kindergartens. Nutrition information including amounts of consumed dairy products, meat and processed meat products, nuts and seeds, white bread and refined grains, fruits, vegetables, simple sugars, fats and drinks was obtained through a questionnaire. Linear mixed-effects models were fitted with polymerase chain reaction (PCR) plate ID and kindergartens as random effects to estimate the association of each food group consumption with LTL, controlled for relevant covariates. Higher consumption of dairy products and sugar was associated with shorter LTL (β = -0.180, 95% confidence interval [CI]: -0.276, -0.085, P value <0.001 and β = -0.139, 95% CI: -0.193, -0.086, P value <0.001, respectively). An increase in consumption of fish, nuts and seeds, coloured fruits, green leafy vegetables, cruciferous vegetables and olive was significantly associated with the increase in relative LTL. The associations for the consumption of legumes, other fruits, yellow and orange vegetables, red meat, egg, white bread and refined grains, solid and liquid fats, processed meats, potato chips, carbonated drinks, tea (black) and soft drinks groups were not statistically significant. Our findings showed that there was an association between the consumption of certain food groups with LTL.

Mean of serum albumin and total protein were normal at the beginning of the study, which was significantly reduced at the end of study (P = 0.01 and 0.01). Mean of energy, macronutrients, and micronutrients intake indicated a significant reduction from the beginning to the end of treatment (P < 0.05). Conclusion: Findings of this study showed that the mean of serum albumin, total protein and energy, macronutrients, and micronutrients intake indicated a significant reduction from the beginning to the end of treatment in this research.

Local Usage of Nigella sativa Oil as an Innovative Method to Attenuate Primary Dysmenorrhea: A Randomized Double-blind Clinical Trial

Objectives

We sought to determine the effect of topical application of Nigella sativa (black seed) oil, on the primary dysmenorrhea intensity.

Methods

We conducted a randomized, double-blind clinical trial on 124 female students, 18–22 years old, living in the dormitories of Sabzevar Universities. After a primary assessment, participants were randomly divided into two groups. The first group rubbed two drops of N. sativa oil, and the second group rubbed liquid olive oil, as the placebo. Massage was performed on the fontanel lobe 3, at night, three days before menstruation, for eight consecutive days (about five days after menses). This procedure was repeated for three menstrual cycles. After three cycles, pain severity was measured by the visual analog scale. Data analysis was carried out using the Mann-Whitney U test and analysis of covariance (ANCOVA).

Results

This study was conducted on 124 female students. The mean age of students, mean age of first menarche, body mass index, and pain severity were not significantly different in the two groups (p > 0.050). No adverse effects were observed during the study. The results of ANCOVA showed that pain intensity in N. sativa oil group was significantly decreased compared to that of the placebo group (0.6 score; p < 0.050).

Conclusions

N. sativa could be a promising, safe, and easily available analgesic supplement in women suffering from primary dysmenorrhea.

Effect of Nigella sativa oil supplement on risk factors for cardiovascular diseases in patients with type 2 diabetes mellitus

This study aimed to evaluate the effects of Nigella sativa oil on serum level of systemic inflammation, oxidative stress, fasting blood glucose (FBG), and lipid profile in patients with type 2 diabetes mellitus (T2DM). This double-blind randomized clinical trial study was based on 50 patients with T2DM. Patients were allocated randomly to either N. sativa oil or placebo groups. The intervention group received 1,000 mg N. sativa oil as two capsules, daily for 8 weeks, whereas the placebo group received a corresponding placebo. At baseline and the end of the study, 5 ml blood was collected from each patient after 14-hour fasting for measuring serum C-reactive protein (hs-CRP), malondialdehyde (MDA), FBS, and lipid profile. Analyses covariance was performed to compare investigated parameters between two groups, controlled for relevant covariates. Using N. sativa supplement was significantly associated with decrease in FBS (p < .001), triglyceride (p < .001), total cholesterol (p < .001), low-density lipoprotein cholesterol (p < .001), serum hs-CRP, MDA (p < .001) and increase in serum level of high-density lipoprotein cholesterol (p < .001) in intervention group compared with placebo group. Nigella sativa oil supplement has cardiovascular protective effects in patients with T2DM, by improving the lipid profile and glycemia, by reducing the C-reactive protein level and the lipid peroxidation.

Background: Hypertension is the third risk factor for the cardiovascular diseases. This study investigated the effects of mineral water from Damavand spring on the blood pressure and serum lipid profiles in men with hypertension. Methods: In this study 41 hypertensive men were randomly assigned to Damavand mineral water (DM) and Tehran water groups (TW). The DM and TW received 1.5-liter bottle of mineral water of Damavand spring and Tehran piped water bottled, respectively. The participants' blood pressure, serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDLc), and high-density lipoprotein cholesterol (HDLc) were measured at the beginning and end of the study. Total hardness of water was measured by titration with EDTA. Results: The results showed that the mean systolic and diastolic blood pressures decreased in both groups at the end of the study compared to the baseline (P < 0.05), but the difference was not significant. Serum TC and LDLc significantly in the case group at the end of week 8 compared to the baseline (P < 0.05) and this reduction was significant (P < 0.05). Moreover, no significant differences were observed between the two groups with regard to the mean changes of TG and HDLc (P > 0.05). Conclusions: The findings showed that the daily consumption of 1.5 liters of premium mineral water of Damavand springs decreased the systolic and diastolic blood pressure, total cholesterol, and LDLc levels.

Effects of fenugreek seed powder on stress-induced hyperglycemia and clinical outcomes in critically ill patients: A randomized clinical trial

Introduction: Stress-induced hyperglycemia (SIH) is commonly observed in critically ill patients and associated with poor clinical outcome for patients. Fenugreek seed powder has long been known as an anti-diabetic drug since its pharmaceutical properties were demonstrated. Materials: The study herein was a parallel, randomized controlled clinical trial consisting of 60 adult patients randomly divided into 2 groups (n=30 per group). The study was conducted in Sabzevar, Iran in April 2015. The intervention group received 3 g of fenugreek seed powder by gavage, twice a day, in addition to routine care. The control group received only routine care. In the beginning, a daily evaluation of fasting and postprandial blood sugar was conducted for 10 days. Secondary components (prevalence of pneumonia; length of intensive care unit (ICU) stay, length of hospital stay, ventilator days, APACHE II score, and mortality rate) were measured until the time of hospital discharge or death. Data were analyzed via SPSS v.20 using Student's t-test (paired and unpaired), chi-square test, repeated measure ANOVA, and Wilcoxon test. Results: In during 10 days of treatment, there was a significant fall in mean glucose levels in 2 groups. However, this improve was more significant in Intervention group in compared to control group (p<0.001). Conclusion: The present study suggests that daily diet with fenugreek seeds can be used as an add-on therapy with other medications in the management of SIH in critically ill patients.

Nutritional intake and its association with educational achievement in high-school students in Islamic Republic of Iran

BACKGROUND

Inadequate food intake can affect learning and memory. Studies on the nutrient intake of adolescents in Sabzevar are lacking.

AIMS

This study assessed the nutrient intake of high-school students in Sabzevar and its association with academic attainment.

METHODS

This cross-sectional study was conducted on 800 of 8 000 high-school students in Sabzevar. Stratified sampling was used. Demographic data and academic information were collected and the parents of the students completed a food frequency questionnaire which included 189 food items. The students' weight and height were measured using standard methods. Each food was coded using Nutritionist IV software and mean values of nutrients (13 vitamins/minerals, 4 food types and total energy) were calculated.

RESULTS

The mean body mass index of female and male students was 20. 3 (SD 2.7) kg/m2 and 19.5 (SD 3.2) kg/m2 respectively. The intakes of energy, vitamins A, C, D, folic acid, calcium, iron and zinc were significantly lower than the dietary reference intake (P < 0.05). A statistically significant correlation was seen between iron intake and academic scores in female students (P < 0.05) but not for any other nutrient.

CONCLUSIONS

The intake of most nutrients in high-school students in Sabzevar was lower than the dietary reference intake. Nutrition education and nutritional support strategies are recommended to improve the nutritional status of these students.

Effects of fenugreek seed powder on enteral nutrition tolerance and clinical outcomes in critically ill patients: A randomized clinical trial

Background: Enteral nutrition (EN) intolerance is a common complication in critically ill patients that contributes to morbidity and mortality. Based on the evidence of curing effects of fenugreek seeds in some gastrointestinal disorders, this study aimed to determine the effects of fenugreek seed powder on enteral nutrition tolerance and clinical outcomes in critically ill patients. Materials & Methods: A randomized, double-blinded clinical trial of 5-day duration was conducted on 60 mechanically ventilated patients divided in 2 groups (n=30). Group 1 was given fenugreek seed powder by gavage, twice a day in addition to routine care, while Group 2 received only routine care. Enteral nutrition tolerance and clinical outcomes were measured throughout the study. Demographic and clinical data were recorded and clinical responses to the primary outcome (enteral nutrition tolerance) and secondary outcome (other clinical factors) were interpreted. Data were analyzed using the independent t-test, Chi-squared test, covariance analysis, and repeated measure ANOVA via SPSS statistical software (v. 20); statistical significance was set at p< 0.05. Results: Patients who were fed with the fenugreek seed powder showed a significant improvement in enteral nutrition tolerance, as well as some complications of mechanical ventilation for Group 1, as compared with Group 2. The mortality rates were not different between the two groups. Conclusion: This study shows the beneficial effects of fenugreek seeds on food intolerance in critically ill patients and that the seed powder can be used as an add-on therapy with other medications. Thus, the use of fenugreek seeds to treat mechanically ventilated patients is recommended.

Prebiotic prophylaxis of ventilator-associated pneumonia: A randomized clinical trial

Introduction: There is evidence of the curing effects of prebiotics in promoting growth of bifid bacterium in the digestive system and the central role of bacteria colonization in the pathogenesis of ventilator-associated pneumonia (VAP). The purpose of this study was to evaluate the effects of administration of a prebiotic, namely fenugreek seeds, on VAP prevention and clinical outcomes in critically ill patients. Methods: In this study, 60 mechanically ventilated patients were randomly divided into 2 groups (n=30 per group). Group 1 was given fenugreek seed powder by gavage, twice a day in addition to routine care, while group 2 received only routine care. Demographic and clinical data were recorded and clinical responses to the primary component (prevalence of VAP) and secondary component (other clinical factors) were interpreted. Data were analyzed via SPSS v.20, using student t-test, chi-square test, repeated measure ANOVA, and Wilcoxon test. Result: There was a significant reduction of patients diagnosed with VAP, as well as clostridium difficileassociated diarrhea and some complications of mechanical ventilation, in group 1 when compared to group 2. In addition, improvement in VAP was significantly greater for group 1 as compared with group 2. Mortality rates were not different between the two groups. Conclusion: The present study demonstrated that daily diet with fenugreek seeds can be used as an add-on therapy with other medications in prevention of VAP. As a result, the use of fenugreek seeds in the treatment plan of patients undergoing long-term intubation is recommended.

Effectiveness of supplementary blended flour based on chickpea and cereals for the treatment of infants with moderate acute malnutrition in Iran: A randomized clinical trial

Background

Despite the decreasing rate of under nutrition children in recent years overall, the negative affect in growth and development make it as a main concern in the world. Applying an available and appropriate supplementary food is a major approach in treating children with Moderate Acute Malnutrition (MAM).

Objective

To compare the effectiveness of a new supplementary blended flour (containing chickpea, rice, wheat and barley, named Shadameen) in combination with multivitamin/mineral supplement and nutritional counseling versus multivitamin/mineral supplement and nutritional counseling alone, in the treatment of children with MAM.

Methods

This randomized controlled trial study was conducted at Heshmatiyeh Hospital in Sabzevar city in Iran, from January 2016 to December 2016. Seventy infants, aged 9 to 24 months with MAM who were referred from urban health centers to the hospital clinic were included. They were randomly assigned to receive, for about 3 months, either multivitamin / mineral supplement and nutritional counseling alone or in combination with an extra supplementary blended food. We analyzed weight, length, weight for length Z score (WLZ), weight for age Z score (WAZ) and length for weight Z score (LAZ), along with recovery rate and adverse events among the two groups. The data were analyzed using SPSS version 16. We used statistics, Chi-square, independent t-test, and Fisher’s exact test for the analyses of primary and secondary outcomes.

Results

The food supplementation infant’s mean weight and WLZ and WAZ were greater compared with the other group (0.81±0.29 gr and 0.55±0.33 gr, p=0.002), (0.36±0.36 and 0.02±0.52, p=0.003), (0.40±0.33 and 0.09±0.37, p=0.001). The recovery rate in the food supplemented group was significantly higher than the other group (68.4%, 31.6%, p=0.001). No adverse reactions were observed. There were no significant differences in LAZ at the end of the study between the two groups (p=0.53).

Conclusion

This study showed that Shadameen in combination with multivitamin/mineral and counselling therapy can be more effective in decreasing the wasting rate of children with MAM than vitamin/mineral and counseling therapy alone.

Methods

This cross-sectional study was conducted on 125 women with breast cancer in Sabzevar in 2011. Census sampling was done on volunteers in a visiting home and suspected women referred to the mammography, ultrasound, and radiology clinic in the Sabzevar center for breast cancer. Demographic and semi quantitative food questionnaires of 160 foods were completed for each of the patients by trained interviewers. Data were analyzed using the software Nutritionist IV. Descriptive statistics, one-sample t-test, and Chi-square test were used, employing the SPSS version 16.

Results

In this study, 125 women were assessed with breast cancer. The highest risk with breast cancer was 35.5% in women 40 to 49 years old. The results of this study showed that patients with breast cancer had minimum daily recommended intake (3.06 ± 2.3 serving of fruits and 2.09 ± 1.81 serving of vegetables in days). One sample t-test showed that the mean intake of fruits and vegetables was not a significant deference with daily recommended intake (p>0.05). The chi-square test showed that patients with minimum daily recommended intake of fruits and vegetables were at high risk for breast cancer in comparison with those who received the highest amount (p=0.001).

Conclusion

This study supports evidence that high vegetable and fruit intake is associated with lower breast cancer risk.

The Relationship Between Breastfeeding and Measurements of Refraction and Visual Acuity in Primary School Children

BACKGROUND

Nutrition has been implicated in the development of some refractive errors. This study aims to investigate the relationship between refractive errors, visual acuity (VA), and Breastfeeding.

METHODOLOGY

In this cross-sectional study, cluster sampling was used to select 400 children aged 1-5. Fieldwork for the main study took place from September 2005 to May 2006 in two public schools of Sabzevar, Iran. Breastfeeding was defined as 6 months or more feeding. A significant refractive error was defined as at least -0.50 diopters (D) for myopia, +0.50D for hyperopia, and -0.50D for astigmatism. In addition, refractive error was calculated by converting it to spherical equivalent (SE). Statistical analysis used includes Descriptive statistics; Spearman correlation coefficients; one-way ANOVA; independent sample t-test; and Pearson chi-square test.

RESULTS

Finally, 367 children were selected: 156 boys (42.5%) and 211 girls (57.5%). Three hundred eleven subjects (85%) had Breastfeeding. According to SE in right eye, 25.5% and 5.2% of the subjects were hyperopic and myopic, respectively, in the breastfed group, compared to 26.8% and 5.4% in the non-Breastfeeding group. In addition, hyperopia and myopia were less observable in breastfeeders than the other group for left eye. Mean VA and refractive error were different according to feeding type, but this study did not show statistically significant differences between the two groups; however, for exact judgment about these findings, more studies are suggested with a larger sample size.

CONCLUSION

In conclusions based on the results, there was no significant relationship between kind of feeding during the first 6 months of infancy and VA and refractive errors.

The association between serum C-reactive protein and macronutrients and antioxidants intake in hemodialysis patients

Background:Despite the high levels of inflammation in hemodialysis patients and the effects of diet on systemic inflammation, such as the development of atherosclerosis and cardiovascular disease, few studies have evaluated the relationship of macronutrients and antioxidants intake with serum C-reactive protein (CRP). Therefore, this study assessed the relationship between serum high sensitivity CRP (hs-CRP) with macronutrients and antioxidants intake and serum albumin. Methods:This cross-sectional study used census sampling to select 75 hemodialysis patients (35 men and 40 women) who attended the hemodialysis department of Vaseie Hospital of Sabzevar, Iran. After obtaining the written consent, all the patients were interviewed and dietary data was collected by using a semi-quantitative food frequency questionnaire including 160 food items. Diet analysis was performed with Nutritionist IV. Before being connected to the dialysis machine, 5 cc fasting blood samples were obtained from all participants and serum hs-CRP and albumin levels were measured. All the statistical analyses were conducted with SPSS -for Windows, version 16.0. Results:The patients' mean body mass index was 20.09 ± 3.27 kg/ m2. The participants' intake of antioxidants and all macronutrients, except for carbohydrates and proteins, was less than the standard levels. Moreover, the hs-CRP had significant inverse relationships with serum albumin (P=0.0001) and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy (P=0.002) and protein (P=0.0001). Conclusion:Our findings indicated hs-CRP levels of hemodialysis patients to have significant inverse relationships with serum albumin and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy and protein.
