Prevalence of supplement usage and related attitudes and reasons among fitness athletes in the gyms of Kashan and its relationship with feeding behavior: a cross-sectional study.

BACKGROUND: The overuse of supplements among athletes is a widespread issue affecting the health of both male and female athletes. However, research on supplements usage among female fitness athletes is limited, and there is little information on the feeding behavior of fitness athletes who use supplements. This study aimed to fill the gap in knowledge by examining the prevalence of supplement usage and its related attitudes and reasons among fitness athletes in the gyms of Kashan. It further aimed to investigate the correlation between supplements usage and the feeding behavior of fitness athletes. METHODS: For these purposes, in this cross-sectional study, 433 fitness athletes (15‒46 years old) in 28 gyms in the city of Kashan were surveyed using a researcher-made questionnaire in 2023. Five experts confirmed the validity of the questionnaire. The present study considered the supplements based on the Australian Institute of Sport position statement. A Chi-square analysis was conducted to examine the relationship between the study variables and supplement usage. RESULTS: Overall, 272 male and 161 female fitness athletes participated in this study. The results revealed that 57.9% of participants used supplements, most commonly vitamin C, vitamin D, omega-3 fatty acids, and whey protein. The main reason for using supplements was to speed up body repair after exercise (69.5%). Additionally, 41.8% of these athletes believed that using supplements improves their overall performance, and 21.9% thought that supplements do not harm the body. Moreover, a correlation was observed between feeding behavior and the consumption of supplements. It was found that athletes who use supplements tend to eat more white meat, seeds, and nuts and fewer high-fat dairy products than those who do not consume them. CONCLUSION: Using supplements among fitness athletes in the gyms of Kashan is common. The main reason for using these substances was to speed up body repair after exercise, and nearly half of the athletes believed that supplements improved their performance. In addition, it was revealed that athletes who take supplements have healthier feeding behaviors than those who do not. Thus, these findings confirm the necessity of informing fitness athletes about using supplements.

The effects of probiotics supplements on metabolic indices and clinical signs in patients with diabetic retinopathy, a randomized double blind clinical trial.

Purpose: This study was carried out to evaluate the effects of probiotics administration on clinical status and metabolic profiles in diabetic retinopathy (DR) patients. Methods: This randomized, double-blind, placebo-controlled trial was conducted among 72 DR patients. Subjects received probiotics including Lactobacillus acidophilus, Bifidobacterium bifidum, Bifidobacterium langum, Bifidobacterium lactis daily (2 × 109 CFU/each strain) (n = 36) or placebo (starch) (n = 36) and were instructed to take one capsule daily for 12 weeks. Finally, 55 participants [probiotic group (n = 30) and placebo group (n = 25)] completed the study. Fasting blood samples were obtained at baseline and after the 12-week intervention to determine metabolic profiles. To determine the effects of probiotic supplementation on clinical symptoms and biochemical variables, we used one-way repeated measures analysis of variance. Results: After the 12-week intervention, compared with the placebo, probiotic supplementation significantly decreased means serum insulin concentrations (Probiotic group: -4.9 ± 6.5vs. Placebo group: 3.0 ± 7.7 µIU/mL, Ptime×group<0.001), homeostatic model assessment for insulin resistance (Probiotic group: -2.5 ± 3.8 vs. Placebo group: 1.1 ± 2.7, Ptime×group<0.001) and hemoglobin A1c (HbA1C) (Probiotic group: -0.4 ± 0.7 vs. Placebo group: -0.02 ± 0.2%, Ptime×group=0.01), and significantly increased the quantitative insulin sensitivity check index (QUICKI) (Probiotic group: 0.02 ± 0.03 vs. Placebo group: -0.03 ± 0.04, Ptime×group<0.001). There was no significant effect of probiotic administration on other metabolic profiles and clinical symptoms. Conclusions: Overall, probiotic supplementation after 12 weeks in DR patients had beneficial effects on few metabolic profiles. This study was registered under the Iranian website for clinical trials as http://www.irct.ir: IRCT20130211012438N29.

Effects of Selenium Supplementation on the Indices of Disease Activity, Inflammation and Oxidative Stress in Patients with Rheumatoid Arthritis: a Randomized Clinical Trial.

The aim of study was to evaluate the effect of selenium supplementation on disease activity, inflammation, and oxidative stress in patients with rheumatoid arthritis (RA). This study was a randomized double-blind placebo-controlled trial on 59 patients with RA. Participants were randomly divided to receive 200 µg/day of selenium or a placebo for 12 weeks. The disease activity score (DAS.CRP and DAS.ESR), erythrocyte sedimentation rate (ESR), serum levels of C-reactive protein (CRP), fasting blood glucose, lipids, antibodies to cyclic citrullinated protein (anti-CCP), nitric oxide, glutathione, and total antioxidant capacity were assessed. The mean of DAS.CRP and DAS.ESR decreased significantly within both study groups after the intervention. However, the between-group comparisons revealed no significant differences. The CRP levels decreased significantly in the selenium group, and this decrease was near the significance level compared to the placebo (P = 0.05). However, after adjusting for baseline values, the observed difference between groups did not remain significant. In addition, the values of ESR and anti-CCP decreased significantly within the selenium group. Although, between-group comparison did not statistically significant, the change in ESR and anti-CCP in the selenium group was small clinically relevant compared to the placebo [the effect size (95% CI) for ESR: 0.38 (- 0.14, 0.89), and for anti-CCP: 0.32 (- 0.2, 0.83)]. Our study showed that selenium caused a small clinically relevant improvement in some RA biomarkers such as ESR and anti-CCP. Future studies that evaluate the effects of novel forms of supplements such as selenium nanoparticles on the clinical symptoms and biomarkers of RA are suggested. Trial Registration: At www.irct.ir as IRCT20190924044869N1 on 2020-06-14.

Dietary Magnesium Intake and Proteinuria: Is There a Relationship?

The possible relationship between dietary magnesium status and proteinuria has been suggested by a number of previous studies. However, human studies on this association are limited. Therefore, the present study aimed to investigate the independent relationship between dietary magnesium intake and urinary protein excretion. The present study was a post hoc analysis of the previous randomized clinical trial that evaluated the effect of dietary phosphorus restriction on proteinuria. The baseline data of 90 participants with proteinuria and chronic kidney disease was used to measure the association between dietary magnesium intake and proteinuria. Participants were asked to record their 24-h food intake for three days a week in a questionnaire. Urinary protein to creatinine ratio (UPCR) in a random urine sample was measured to be a marker for proteinuria. Out of 90 patients included in the study, 47 were men and 43 were women. The mean ± standard deviation of age and body mass index were 59.05 ± 14.16 years and 29.02 ± 5.54 kg/m2, respectively. The patients' average daily dietary intake of energy and magnesium were 2183 kcal and 169.44 mg, respectively. A significant inverse correlation was found between the dietary intake of magnesium and UPCR (r = - 0.219, p = 0.042). This association remained significant even after adjusting for confounding variables (ß = - 0.222, p = 0.028). The findings of the present study showed a significant inverse relationship between the magnesium intake and proteinuria. Although, the design of the current research was cross-sectional, it has provided a basis for conducting future longitudinal studies and trials to better elucidate such a relationship.

The effect of yoga therapy directed by virtual training on depression of adolescent girls with type 1 diabetes: a randomized controlled trial.

Background: Recently, the depression-alleviating impact of yoga therapy was documented among patients with type 2 diabetes; nonetheless, whether this consequence is similar in individuals with type 1 diabetes (T1D) is still unclear. Therefore, this trial sought to investigate the potential impact of yoga therapy on the depression of adolescents with T1D. Methods: This randomized controlled trial recruited 62 girls with T1D, aged 12-17 years, from January to June 2020. The participants were randomly allocated to equal experimental and control arms (31 per group) through a block randomization approach. The routine care was implemented in two study arms, while the experimental arm additionally received yoga therapy directed by virtual training for eight consecutive weeks (one session per week). Maria Kovacs Children's Depression Inventory was completed at baseline and the end of the 8-week intervention. Results: The mean of the depression total score was significantly lower in the experimental arm in comparison with the control arm at the trial end (9.38 ± 8.44 vs. 12.77 ± 6.96, p = 0.014). Also, the reduction in mean change from the baseline to the trial end was significantly more in the experimental arm (- 5.25 ± 1.13 vs. - 0.80 ± 1.00, p = 0.013). Conclusions: The administration of yoga therapy directed by virtual training seems to be potentially effective in reducing depression among adolescent girls with T1D. However, further long-term trials with a larger sample size are needed to shed light on the obtained findings and address the intervention's efficacy on glycemic outcomes.

The Relationship between Metacognitive Beliefs with Clinical Belongingness and Resilience among Novice Nurses in Neonatal Intensive Care Units.

Background: The neonatal intensive care unit (NICU) is a sensitive ward for nurses. However, the low nurse-to-patient ratio has led to the hiring of novice nurses into the critical areas such as NICUs. These nurses are in need of help in the clinical environment as they have no much experience caring the neonates in the real clinical setting. Therefore, it is necessary to address the individual and psychological capacities with the help of which a person can overcome the difficult situations. This study aimed to investigate the relationship between metacognitions, clinical belongingness, and resilience of novice nursing staff in NICU wards. Method: This study is a descriptive-analytical study, and the research samples were composed of 78 novice nursing staff of Neonatal Intensive Care Units from teaching hospitals. Samples were selected via a purposive sampling method. Research tools included demographic, Wells and Hatton metacognitive beliefs, Jones Levitt belonging, and Connor-Davidson resilience questionnaires. SPSS 22 software was used for data analysis. Results: The mean score of metacognitive beliefs in novice nursing staff was 92.67 ± 13.69, and it was 116.69 ± 19.11 for belongingness and 78.78 ± 14.73 for resilience. There is positive and significant relationship between metacognitive beliefs and belongingness (p < 0.019, r = 0.265). In addition, the relationship between metacognitive beliefs and resilience in novice nursing staff was positive and significant (p < 0.001, r = 0.359). Conclusion: There is a positive relationship between metacognitive beliefs with belongingness and resilience of novice nurses; nursing managers can consider educational metacognition workshops to enhance the sense of belongingness and resilience of novice nursing staff leading to improve their clinical performance in neonatal care.

Effects of Folic Acid Supplementation on Liver Enzymes, Lipid Profile, and Insulin Resistance in Patients with Non-Alcoholic Fatty Liver Disease: A Randomized Controlled Trial.

Background: Previous evidence revealed an association between folate deficiency and non-alcoholic fatty liver disease (NAFLD). This study is the first one investigating the effects of folic acid on hepatic steatosis grade, liver enzymes, insulin resistance, and lipid profile in NAFLD cases. Materials and Methods: Sixty-six participants with NAFLD were allocated randomly to take either a placebo or one oral tablet of folic acid (1 mg) on a daily basis within eight weeks. Serum folate, homocysteine, glucose, aminotransferases, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), and lipids were assessed. Ultrasonography was used for assessing the liver steatosis grade. Results: The serum alanine transaminase, grade of hepatic steatosis, and aspartate transaminase significantly were decreased within both study groups; however, the between-group comparison was not statistically significant. Of note, the decrease in ALT was more pronounced in folic acid compared with the placebo group (-5.45 ± 7.45 vs. -2.19 ± 8.6 IU/L). The serum homocysteine was decreased after receiving folic acid compared to the placebo (-0.58 ± 3.41 vs. +0.4 ± 3.56 µmol/L; adjusted P = 0.054). Other outcomes did not significantly change. Conclusion: Supplementation with folic acid (1 mg/d) for eight weeks among cases with NAFLD did not change significantly the serum levels of liver enzymes, the hepatic steatosis grade, insulin resistance and lipid profile. However, it was able to prevent the increase in homocysteine in comparison with the placebo. Conducting further research is suggested with the longer duration and different doses of folic acid, adjusted to the genotypes of methylenetetrahydrofolate reductase polymorphism, among NAFLD patients.

Nigella sativa supplementation and non-alcoholic fatty liver disease: A systematic review of clinical trials.

Objective: Based on the results of previous studies, the effects of N. sativa on some of the non-alcoholic fatty liver disease's (NAFLD) biomarkers were positive; however, there were conflicting results regarding other variables. Therefore, the present systematic review of clinical trials was designed to clarify whether N. sativa effectively prevents the progression of NAFLD. Materials and Methods: A search of four databases (Scopus, PubMed, Medline, and Google scholar) was conducted to identify the clinical trials that assessed the effects of N. sativa supplementation on NAFLD. The outcome variables of interest were biomarkers of hepatic steatosis, liver enzymes, insulin resistance, and inflammation. Results: Overall, four randomized clinical trials (RCTs) were included. In three studies, hepatic steatosis grade decreased significantly after N. sativa supplementation. Serum levels of liver enzymes reduced significantly in three of four included trials. In the only study that examined the effect of N. sativa on insulin resistance parameters, all variables related to this factor were significantly reduced. In two included studies that measured biomarkers of inflammation, the serum levels of tumor necrosis factor α (TNF-α), high-sensitive C-reactive protein (hs-CRP), and interleukin 6 (IL-6) decreased significantly after intaking N. sativa supplements. Conclusion: Although the efficacy of N. sativa on liver enzymes and the grade of hepatic steatosis was reported in some of the included studies, more well-designed clinical trials are needed to determine the definitive effects of N. sativa on NAFLD. The present study provides suggestions that help to design future studies in this field.

Dietary Acid Load and Predialysis Serum Bicarbonate Levels in Patients With End-Stage Renal Disease.

OBJECTIVES: Maintaining the predialysis serum bicarbonate at a recommended level is critical in patients undergoing hemodialysis. Therefore, the present study investigated the association between dietary acid load (DAL) and serum predialysis bicarbonate levels in patients with end-stage renal disease. METHODS: Adult patients undergoing hemodialysis were enrolled in this cross-sectional study. Diet was assessed using a semiquantitative food frequency questionnaire. DAL was calculated with 2 validated indices: potential renal acid load (PRAL) and net endogenous acid production (NEAP). Values regarding predialysis serum bicarbonate level and serum electrolytes were obtained from the participant's medical records. The multiple linear regression analysis was used to determine the association between DAL indices and predialysis serum bicarbonate level. RESULTS: The number of hemodialysis patients eligible for this study was 122. The participants' mean age and body mass index was 57.14 ± 3.8 years and 25.2 ± 4.9 kg/m2, respectively. About 65.6% of participants were male. The mean serum levels of predialysis bicarbonate were 21.59 ± 3.1 mEq/L. Also, 47.5% of patients had predialysis serum bicarbonate levels below the recommended value. The mean values of PRAL and NEAP were -2.8 ± 7.48 and 42.7 ± 10.1 mEq/day, respectively. PRAL significantly and inversely predicted predialysis serum bicarbonate level independent of covariates (standardized ß = -0.38; P < .001). Also, NEAP was independently and inversely associated with predialysis bicarbonate level (standardized ß = -0.40; P < .001). Consuming vegetables such as lettuce, tomato, cucumber, spinach, and dried fruits as well as low-fat milk, plain yogurt, and cream cheese were positively correlated to predialysis serum bicarbonate level. However, the canned tuna had a negative correlation with the predialysis serum bicarbonate. CONCLUSIONS: The study's findings showed that the lower DAL was associated with higher predialysis serum bicarbonate levels in patients with end-stage renal disease. Due to the cross-sectional nature of the present study, prospective cohorts or well-controlled clinical trials are needed to confirm our result.

Association of Zinc Status with Matrix Metalloproteinases, Advanced Glycation End-Products, and Blood Pressure in Patients with Chronic Kidney Disease.

Inflammation, oxidative stress, and hypertension trigger the development of chronic kidney disease (CKD). Zinc is known to have antioxidant and anti-inflammatory properties and a possible role in regulating blood pressure. The aim of this study was to investigate the correlation of serum zinc with matrix metalloproteinase-2 and-9 (MMP-2, MMP-9), advanced glycation end products (AGEs), and blood pressure in patients with CKD. This cross-sectional study included 90 patients with CKD. Serum zinc and the levels of MMP-2, MMP-9, AGEs, and creatinine were measured using validated biochemical methods. Three 24-h food recalls were completed to evaluate dietary zinc intake. Systolic and diastolic blood pressure (SBP, DBP) were measured using a digital sphygmomanometer. Participants' mean age was 60.68 ± 8.81 years. The prevalence of zinc deficiency in our participants was 10%. Serum zinc was negatively correlated with MMP-9 (r = - 0.231, p = 0.032) and creatinine (r = - 0.304, p = 0.004). However, after adjusting for confounding variables, the association between serum zinc and MMP-9 was near the significance level (ß = - 0.174, p = 0.09) and zinc remained in the model as one of the predictors. Serum zinc was positively correlated with the dietary intake of zinc (r = 0.241, p = 0.025) and estimated glomerular filtration rate (eGFR) (r = 0.259, p = 0.015). In conclusion, our results showed that serum zinc might be one of the predictors of serum MMP-9 in patients with CKD. In addition, serum zinc was positively associated with its dietary intake and eGFR. Future longitudinal studies or clinical trials are required to reveal any causal association between zinc status and profibrotic or inflammatory biomarkers among patients with CKD.

Nanoplastics: Focus on the role of microRNAs and long non-coding RNAs.

When plastic objects in our surroundings are degraded, they may produce particles ranging in size from 1 to 100 nm therefore called nanoplastics. The environmental chemicals including nanoplastics may be able to affect biological processes in the nuclear level like altering DNA methylation and regulating microRNAs (miRNAs) as well as long non-coding RNAs (lncRNAs) expression and therefore are implicated in chronic human diseases like neoplasms. The regulatory role of miRNAs and lncRNAs in gene expression is appreciated. In vitro as well as in vivo experiments have shown that environmental elements including nanoplastics are able to dysregulate miRNAs and lncRNAs expression with possible genetic consequences that increase the risk of cancer development. In the current article, we review the biological effects of miRNAs and lncRNAs alterations following nanoplastics exposure.

The effects of vitamin B12 supplementation on metabolic profile of patients with non-alcoholic fatty liver disease: a randomized controlled trial.

The present study is the first effort to evaluate the effects of vitamin B12 supplementation on the serum level of liver enzymes, homocysteine, grade of hepatic steatosis, and metabolic profiles in patients with non-alcoholic fatty liver disease (NAFLD). Forty patients with NAFLD were enrolled in a double-blind placebo-controlled trial to receive either one oral tablet of vitamin B12 (1000 µg cyanocobalamin) or a placebo per day for 12 weeks. We investigated serum levels of homocysteine, aminotransferases, fasting blood glucose (FBG), lipids, malondialdehyde (MDA), and homeostasis model assessment of insulin resistance (HOMA-IR). The grade of liver steatosis and fibrosis was measured by real-time 2-dimensional shear wave elastography. Vitamin B12 supplementation significantly decreased serum levels of homocysteine compared to placebo (medians: - 2.1 vs. - 0.003 µmol/l; P = 0.038). Although serum alanine transaminase (ALT) in the vitamin B12 group decreased significantly, this change did not reach a significant level compared to the placebo group (medians: - 7.0 vs. 0.0 IU/l; P > 0.05). Despite the significant within-group decrease in FBG, MDA, and liver steatosis in the vitamin B12 group, between-group comparisons did not reveal any significant difference. Vitamin B12 supplementation might decrease serum levels of homocysteine in patients with NAFLD. The fasting blood glucose and serum levels of MDA were significantly improved in the trial group who received vitamin B12. However, these changes did not reach a significant level compared to the placebo group. In this respect, further studies with larger sample sizes, different doses, and types of vitamin B12 will reveal additional evidence.Trial Registration: At  http://irct.ir/  as IRCT20120718010333N5 on December 25, 2019.

The Effects of Virtual Directed Painting Therapy on Anxiety, Depression, and Self-efficacy of Children with Type 1 Diabetes: A Randomized Controlled Clinical Trial.

Background: Diabetes-induced anxiety, depression, and decreased self-efficacy lead to poor adherence to treatment in diabetic children. Since painting therapy seems to be helpful to express their feelings, this study aimed to investigate the effects of virtual directed painting therapy on anxiety, depression, and self-efficacy in diabetic children. Methods: This randomized controlled trial was conducted on 40 children with type 1 diabetes aged 8-12 years who were referred to Imam Reza Clinic of Diabetes in Shiraz, from July to October 2020. Children were randomly selected and assigned to intervention and control groups, using block randomization. The intervention group received the routine care plus virtual painting therapy directed by WhatsApp (six 2-hour group sessions once a week for six weeks). Spence Children's Anxiety Scale, Maria Kovacs Children's Depression Inventory, and Diabetes Management Self-Efficacy Scale were completed before and after the intervention. Data were analyzed through SPSS 23, using Chi-square, Mann-Whitney U, and Wilcoxon tests. P value <0.05 was considered as significant. Results: After the intervention, the median (interquartile range) total scores for anxiety, depression, and self-efficacy in the intervention group were 48.50 (45.00-51.75), 7.00 (4.00-9.00), and 169.00 (154.00-178.00), and in the control group 55.00 (48.50-62.25), 13.00 (10.00-17.50), and 152.00, respectively (110.50-184.00). After the intervention, there was a significant difference between the groups regarding anxiety (P=0.02) and depression (P<0.001); however, the difference in self-efficacy was not significant (P=0.20). Conclusion: Painting therapy should be considered as a part of care programs in diabetes centers and other community settings to control anxiety and depression of diabetic children.

The effect of training the fathers to support their wives on stress and self-efficacy in mothers of premature newborns hospitalized in NICU: a quasi-experimental study.

BACKGROUND: The birth of premature newborns and their separation from family due to their hospitalization in the Neonatal Intensive Care Unit (NICU) cause stress in the parents, especially mothers. We conducted this study aimed to evaluate whether training the fathers to support their wives impacts premature newborn mothers' stress and self-efficacy or not? METHODS: A quasi-experimental (before-after study) including one experimental and control group was used. Data were collected from Seventy-five parents with newborns hospitalized in NICU (n = 30) in the intervention and (n = 45) in usual care groups. Settings were the NICUs of the two international, educational, specialty, and subspecialty Nemazee and Hafez hospitals of the Shiraz University of Medical Science. Fathers in the intervention group learned how to support their wives and provide care for their premature newborns. The control group received the usual care. Mother's stress and self-efficacy were measured using validated questionnaires. RESULTS: Data analysis showed that the mean scores of mothers' stress and self-efficacy from pre-intervention to post-intervention were significantly decreased and increased respectively in the intervention group (p <0.001). At the same time, there was no significant difference in the control group. CONCLUSION: When fathers are trained to support their wives and do so, it relieves the stress and improves the mothers' self-efficacy, and has a direct effect on providing care to their premature newborns. Therefore, it is recommended that measures should be taken so that the fathers be present, participate in providing care, and support their wives and newborns in NICU.

The Effect of Dietary Phosphorus Restriction on Urine Protein Excretion in Patients With Proteinuria: A Randomized Controlled Trial.

OBJECTIVES: The present study was designed to determine the effect of dietary phosphorus restriction, independent of protein intake, on the urinary protein excretion in patients with proteinuria. METHODS: Seventy-one patients with proteinuria were enrolled in a parallel randomized controlled trial study. The patients were randomly allocated to receive either a recommended phosphorus-restricted diet (n = 36) or a recommended control diet (n = 35), for 8 weeks. A diet was designed and recommended to participants in a way that both trial groups would receive the same amount of energy and protein and the only significant difference between them was the amount of phosphorus intake. The study outcomes included the changes in spot urine protein-to-creatinine ratio, the changes in serum and urine levels of phosphorus, as well as the changes in estimated glomerular filtration rate (eGFR). RESULTS: The mean ± standard deviation of age, body mass index, and eGFR of the participants were 59 ± 14 years, 29 ± 5.5 kg/m2, and 56.1 ± 21.7 mL/min/1.73 m2, respectively. The amount of phosphorus intake decreased significantly in the phosphorus-restricted group compared to the control one (-709 vs. -369 mg/day; P < .001). This decrease is accompanied by a significant reduction in urine protein-to-creatinine ratio in the phosphorus-restricted group; however, this change did not reach a significant level when compared to the control one (the mean change: -75.78 vs. -55.25 mg/g; P = .539). Limiting the phosphorus intake did not change its serum and urine values as well as eGFR at the end of the trial. CONCLUSIONS: Although adherence to a phosphorus-restricted diet by patients with proteinuria led to a significant decrease in urinary protein excretion, this change was not significantly different from that of the control diet. Further studies with larger sample sizes and different designs will reveal more evidence for a link between phosphorus intake and proteinuria.

Screening for domestic abuse and its relationship with demographic variables among elderly individuals referred to primary health care centers of Shiraz in 2018.

BACKGROUND: Elder abuse is an important public health problem. The present study was aimed to determine the rate of domestic abuse and its relationship with demographic characteristics among elderly people referred to Primary Health Care (PHC) centers in Shiraz, Iran, 2018. METHODS: This descriptive and cross-sectional study was conducted on 400 older people aged 60 years old and above who referred to 22 PHC centers of Shiraz. The data were collected using demographic characteristics questionnaire, Katz index, the domestic elder abuse questionnaire, and elder neglect checklist through face-to-face interview and observation methods. Backward linear regression model was used for analyzing the data. RESULTS: The results indicated that 52.5% of the participants were female and 51.8% aged 60-69 years old. A total of 159 cases (39.8%) reflected at least one form of elder abuse or neglect. The results indicated that 21% of the participants (n = 84) were abused by their own children. Care neglect was the most reported form (42.8%), followed by psychological abuse (41.3%), emotional neglect (38.8%), and financial abuse (34.3%). The most common types of neglect were motion limitations (25%) followed by the dental problems (23.8%). The results also showed a significant relationship between domestic elder abuse and level of income (p = 0.017), having a house (p = 0.028), type of perpetrator (< 0.001), and insurance status (p = 0.027). CONCLUSIONS: The results revealed a considerable rate of domestic abuse against elderly people, causing a serious risk for their health and security.

Comparison of Pain-Related and Psychological Variables between Acute and Chronic Migraine Patients, and Factors Affecting Headache Chronicity.

BACKGROUND: Migraine headache is classified as acute or chronic. In recent years, efforts have been made to identify the factors that might predispose individuals to develop the chronic-type headache. The present study aimed to draw a comparison between patients with acute and chronic migraine in terms of demographic, pain-related, and psychological variables. In addition, we also investigated factors affecting headache chronicity in such patients. METHODS: The present cross-sectional study was conducted during 2017-2018. The target sample consisted of 250 patients with acute or chronic migraine who referred to various clinics affiliated to Shiraz University of Medical Sciences (SUMS), Shiraz, Iran, recruited by convenience sampling. All the participants filled in the questionnaires related to demographic characteristics, pain intensity, disability, depression, emotional intelligence, and anger. The data were analyzed using SPSS software (version 22.0) with t test, Chi-square test, and logistic regression analysis. P<0.05 was considered statistically significant. RESULTS: Patients suffering from chronic migraine experienced higher levels of disability, depression, anger, and had lower levels of emotional intelligence compared to those with acute migraine. Based on the logistic regression analysis, variables that had a significant effect on headache chronicity were female gender (OR=5.81), married status (OR=3.77), patients with lower level of education (OR=0.26), headache duration (OR=1.53), disability (OR=0.28), depression (OR=3.66), and anger (OR=5.04). CONCLUSION: Variables such as disability, depression, and lack of anger control were among the key factors associated with headache chronicity in migraine patients.

Anti-cancer effects of cinnamon: Insights into its apoptosis effects.

Cancer is known as a leading cause of death worldwide. In the last two decades, the incidence of cancer has been dramatically increased mostly due to lifestyle changes. The importance of this issue has attracted further attention to discover novel therapies to prevent and treat cancers. According to previous studies, drugs used to treat cancer have shown significant limitations. Therefore, the role of herbal medicines alone or in combination with chemotherapy drugs has been extensively studied in cancer treatment. Cinnamon is a natural component showing a wide range of pharmacological functions including anti-oxidant, anti-microbial and anti-cancer activities. Impaired apoptosis plays critical roles in the initiation and progression of cancer. Increasing evidence indicates that cinnamon, as a therapeutic agent, has anti-cancer effects via affecting numerous apoptosis-related pathways in cancer cells. Here, we highlighted anticancer properties of cinnamon, particularly through targeting apoptosis-related mechanisms.

A comparison between the effects of flaxseed oil and fish oil supplementation on cardiovascular health in type 2 diabetic patients with coronary heart disease: A randomized, double-blinded, placebo-controlled trial.

This study compared the effects of flaxseed and fish oil supplementation on cardiovascular risk parameters in diabetic patients with coronary heart disease. Participants were randomly allocated into three intervention groups to receive either 1,000 mg of omega-3 fatty acids from fish oil or 1,000 mg of omega-3 fatty acids from flaxseed oil or placebo (n = 30 each group) twice a day for 12 weeks. A significant reduction in insulin levels (.04) was observed following flaxseed oil and fish oil supplementation compared with the placebo. In addition, a significant reduction in high-sensitivity C-reactive protein (.02) was seen after flaxseed oil supplementation compared with the placebo and a significant increase in total nitrite (.001) was seen after flaxseed oil and fish oil intake compared with placebo. Additionally, a significant increase in total antioxidant capacity (p < .001) after consuming flaxseed oil and fish oil compared with placebo and glutathione levels (.001) after consuming fish oil compared with flaxseed oil and placebo was observed. Overall, our study revealed the beneficial effects of flaxseed oil and fish oil supplementation on few metabolic profiles. This study suggests that the effect of flaxseed oil in reducing insulin and increasing total nitrite and total antioxidant capacity is similar to fish oil.

The effects of vitamin E supplementation on endometrial thickness, and gene expression of vascular endothelial growth factor and inflammatory cytokines among women with implantation failure.

OBJECTIVE: Data on the effects of vitamin E supplementation on endometrial thickness, and gene expression of vascular endothelial growth factor (VEGF) and inflammatory cytokines among women with implantation failure are limited. This research was performed to determine the effects of vitamin E supplementation on endometrial thickness, and gene expression of VEGF and inflammatory cytokines among women with implantation failure. METHODS: A randomized clinical trial was done among 40 women with implantation failure aged 18-37 years old. Participants were randomly divided into two groups: group A (n = 20) received 400-IU vitamin E supplements and group B (n = 20) received placebo for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week treatment to determine biomarkers of oxidative stress, and gene expression of VEGF and inflammatory cytokines. RESULTS: After the 12-week intervention, compared with the placebo, women with implantation failure who consumed vitamin E supplements had significantly increased serum vitamin E levels (+18.6 ± 15.0 versus -1.5 ± 1.0 nmol/mL, p < .001) and endometrial thickness (+1.1 ± 0.9 versus -0.5 ± 0.3 mm, p = .01), and significantly decreased plasma malondialdehyde (MDA) concentrations (-0.4 ± 0.3 versus +0.4 ± 0.3 µmol/L, p < .004). In addition, results of RT-PCR demonstrated that compared with the placebo, vitamin E intake downregulated gene expression of low-density lipoprotein receptor (LDLR) (p = .008), interleukin-1 (IL-1) (p = .02), and tumor necrosis factor alpha (TNF-α) (p = .007) in peripheral blood mononuclear cells of women with implantation failure. CONCLUSIONS: Overall, vitamin E supplementation for 12 weeks among women with implantation failure had beneficial effects on endometrial thickness, MDA values, and gene expression of LDLR, IL-1, and TNF-α.
