Abnormality in metabolism of lipids and hyperlipidemia is a risk factor for atherosclerosis which is the major cause of cardiovascular diseases (CVDs). Several herbal drugs are used for the treatment of dyslipidemia. The present study investigates the effects of hydroalcoholic extracts of Senna extract on serum lipid profile among hyperlipidemic rats.

Forty eight male Wistar rats were randomly divided into 6 groups of 8 animals, including group 1) normal pellet diet (control), group 2) high fat diet (HFD), group, 3) HFD with 100 mg/kg Senna extract treatment, group 4) HFD with 200 mg/kg Senna extract treatment, group 5) 100 mg/kg pure Senna extract, and group 6) 200 mg/kg pure Senna extract. All the dietary regimens and Senna extract treatments were continued for 30 days. At the end of the experiment, blood samples collected from heart of rats and the lipid profile levels were measured.

The results indicated that short-term treatment by hydroalcoholic of Senna extract produced a significant reduction in the level of cholesterol, triglyceride, and LDL-C (P < 0.05), as well as an increase in HDL-C. The body weight in the HFD group was significantly higher than the other groups (P < 0.05).

Prescription of hydroalcoholic extracts of Senna is effective in the treatment of hyperlipidemia, and can inhibit the weight gain induced by HFD in rats. Some of these effects could be attributed to antioxidants activities, biological and pharmaceutical properties and other protective properties of the Senna extract requiring further investigations

The risk of bone fractures, particularly hip fractures is increasing in the elderly. One of the known factors for predicting fractures is body mass index (BMI) and abdominal obesity. Thus, this study aimed to determine the association between obesity (general and abdominal) with femoral and hip fractures according to gender and age.

In this descriptive cross-sectional study, 100 patients with femoral or hip fractures admitted to the orthopedic ward of Khatam Al-Anbia Hospital in Zahedan were selected between March 2018 and May 2019.  Waist circumference (WC), wrist circumference, BMI, and body size were measured. A P-value of <0.05 was considered as statistical significant. All the analyses were performed by SPSS software version 21.

The highest rate of hip fracture was observed in people aged over 70 years (61.9%, P < 0.01). The highest rate of hip and femoral fractures were observed in individuals with BMI < 23 kg/m2 (P < 0.001) and taller people (>167 cm) (P < 0.0001). The risk of fractures decreased with increasing WC (P < 0.01). Approximately half of those with hip fractures (52.4%) and femoral fractures (51.9%) had small size.

On the basis of our findings, taller height, lower BMI and smaller body size have been suggested as potential contributions to the risk of femoral and hip fractures. It is suggested that abdominal fat may be protective against the risk of hip and femoral fractures at older ages, which requires further research.

Nutrition and dietary habits is one of the determinant factor on glycemic control of diabetes mellitus. This study aims to investigate the association between type 1 diabetes mellitus (T1DM) and diet in the first two years of life as well as a select group of demographic variables.

This case-control study was conducted on 76 children with T1DM and 209 non-diabetic children selected through convenience sampling from the population of people visiting the community health centers of the city of Jahrom, Iran. The required data were collected by a questionnaire of diet and demographic information completed by the mothers of the children. The data were analyzed using logistic regression and adjusted odds ratio.

Finally, the results of multiple backward logistic regression showed that the studied factors had a significant association with T1DM (P < 0.05), including body mass index (BMI) less than 18 kg/m2 for mothers before pregnancy (OR: 4.4, 95% CI: 1.61 to 11.97), mothers without a history of diabetes (OR: 0.02, 95% CI: 0.001 to 0.60), mother’s weight before pregnancy (OR: 0.88, 95% CI: 0.84 to 0.91), mother’s excess weight during pregnancy (OR: 0.83, 95% CI: 0.75 to 0.93), exclusive breastfeeding for more than six months (OR: 0.19, 95% CI: 0.03 to 0.96), low weight gain in the first two years of life (OR: 6.98, 95% CI: 2.16 to 22.5), and the breastfeeding less than 12 months  (OR: 10.52, 95% CI: 1.62 to 66.64).

BMI less than 18 kg/m2 for mothers before pregnancy, low weight gain in the first two years of life, and breastfeeding less than 12 months increased the risk of developing T1DM in children.

Healthy nutrition is a part of a healthy pregnancy. Having a poor food attitude towards healthy nutrition often leads to unfavorable consequences for the mother and her baby. Health care providers need to be aware of these attitudes, so that they can focus their attention on pregnant women during this critical period. Therefore, the present study aims to determine the attitude to healthy nutrition of pregnant women in Yazd city, Iran.

The present cross-sectional descriptive study included 250 pregnant women aged 18-49 years who referred to community health centers, without any background diseases using random sampling method. The face and content validity of the researcher-made questionnaire was confirmed by experts. Its reliability was evaluated by Cronbach's alpha method and completed by self-reporting. The data were analyzed by SPSS software.

The mean score of pregnant women’s attitude towards healthy nutrition was 132.7 ± 22.0. According to the results, despite the obstacles to providing healthy and practical food for pregnant women, such as their high cost, research units sought to provide healthy food during this period. Also, there was an inverse relationship between nutrition-related attitudes during pregnancy and higher pregnancy rates. Multiparous women had fewer misconceptions than primiparous women, which require training of health professionals to prescribe appropriate food attitudes.

In general, it can be inferred that the women of the present study adhered to their nutritional attitudes that originated from their culture, and this study was able to provide a clear picture of the cultural attitudes to healthy nutrition of pregnant women in Yazd.

Food security (FS) is a substantial right of human beings and should be addressed in all groups of the society. This study aims to investigate the prevalence and predictors of food insecurity (FI) among university lecturers in Nangarhar province.

287 university lecturers were selected from public and private universities through stratified random sampling technique. FS was assessed over the past 30 days and through the 10-item short US FS survey module. Data were collected by a well-structured questionnaire in face to face interviews.

Results revealed that 55.05% of university lecturers suffered from FI with a higher prevalence among private university lecturers (P = 0.001). Moreover, FI was significantly associated with ethnicity (P = 0.04), education level (P = 0.01), academic position (P = 0.001), monthly income (P = 0.01), and having another job besides being a lecturer (P = 0.001). Furthermore, lecturers between 36-40 year (OR = 0.043, CI = 0.006-0.292, P = 0.001) with a bachelor's degree (OR = 0.130, CI = 0.033-0.518, P = 0.004) had the lowest odds, and those with senior teaching assistant position (OR = 9.350, CI = 3.371-25.932, P < 0.001), and monthly income of less than 350 US dollar (OR = 162.70, CI = 9.315-2841.92, P < 0.001), had greater odds of FI.

FI is prevalent among university lecturers. Therefore, prompt interventions should be conducted by relevant departments to minimize the risk of FI among the lecturers.

Subcritical water extraction (SWE) is a friendly technique applied to produce rice by-product extract. The aim of this study is using SWE as a new friendly extraction method for producing protein isolates (PI) of rice bran and rice combination as a byproduct of Iranian agriculture product.

D-optimal combined design was used to optimize bran rice ratio, solid/water ratio, extraction time, and particle size to obtain maximum protein. Bran (8-12%) and rice ratio (88-92%) solid water (0.04 -0.12%), time (15-45 min), and particle sizes (420 µm and 710 µm) were selected as independent variables, and protein as dependent variable. After optimization, the effects of extraction parameters on functional properties were investigated.

Increasing bran/rice ratio has a significant effect on the protein extraction. In this study, the optimum SWE conditions were solid water (0.12), bran rice ratio (8:92), time (45 min), particle size (420 µm), and the optimum SWE temperature was obtained at 120 Cº. SWE also could significantly enhance functional properties, such as the solubility, emulsifying activity index (EAI), and degree of hydrolysis of by-product of rice milling (BRM) PI.

According to the positive impact of SWE on protein extraction and the functional properties of BRM PI, this method could be applied as a novel extraction technique to modify the properties of rice protein isolate for functional purposes in the future. However, more investigation is required to study the quantity and quality of the extracted valuable materials to scale it up for industrial means.

Food insecurity and hunger contribute to physical, psychological, and social effects. The relationship between food insecurity and negative consequences on health has been confirmed in multiple studies. The present study aims to identify food security and its association with some demographic factors in children and their parents.

In this descriptive-analytical study, 1688 children aged 3-6 years were selected using cluster random sampling in 15 health centers in Qazvin, Iran.

The results showed that 855 participants (50.7%) had food security, while 552 (32.7%) had food insecurity without hunger, 242 (14.4%) had food insecurity with slight hunger, and 37 (2.2%) had food insecurity with severe hunger. A significant correlation was observed between parental education level and food security (P < 0.001). Also, there was a significant correlation between the children’s body mass index (BMI) and food security (P < 0.005). No significant difference was observed between BMI, mother weight before delivery, and children’s sleeping and wake-up time in both groups. However, the birth rank (P < 0.01) and number of family (P < 0.02) in the secured group was significantly higher. The age of complementary feeding in the secured group was significantly higher (P < 0.06).

Given that there is an association between birth weight, breastfeeding, parents’ education, and occupation with food security, it seems that pregnancy status and breastfeeding should be much more studied.

Obesity as a major cause of low-grade chronic inflammation is a global public health issue. Inflammation arising from obesity affects organs, such as kidney and liver, and is associated with chronic diseases. The present study aims to investigate the association between the dietary inflammatory index (DII) and obesity indices in university students.

This cross-sectional study included 361 college students selected using a two-stage cluster random sampling. The inclusion criteria were healthy girls and boys in the 18-35 years age group, and the exclusion criteria included the presence of chronic diseases, such as diabetes, cardiovascular diseases, taking supplements to weight loss or weight gain, and using alcohol and tobacco. DII scores were calculated from dietary data collected using a semi-quantitative food frequency questionnaire (FFQ). Anthropometric measurements were taken, and body composition was analyzed by bioelectrical impedance analysis (BIA).

The mean age of the students was 21.94 ± 4.04 years, 53.2% were female, and the mean DII was 1.26 ± 1.08. Among the participants, 36.8% were overweight and obese and 9.1% suffered from abdominal obesity. The DII score was not associated with body weight, body mass index (BMI), body fat, waist circumference or visceral fat (both unadjusted and after adjustment for covariates).

The present study showed no association between the DII and obesity indices. Given the proven effects of both the DII and obesity on health indicators, it would be a good strategy to conduct studies with prospective designs to determine the exact effects of DII on obesity indicators.

Following the improvement in health status and life expectancy in developing countries, the elderly population is increasing. Elderly malnutrition is common across healthcare services and is associated with high costs and adverse outcomes. This study assesses the prevalence of malnutrition among elderly patients in the selected hospitals affiliated to Tehran University of Medical Sciences.

This cross-sectional study was conducted on elderly patients aged 65 years or older in 6 selected hospitals between June and September 2015. Using convenience sampling method, a total of 451 patients were included. Nutritional status was assessed using the Mini Nutritional Assessment (MNA) tool.

The mean age of the patients was 71.49 ± 6.60 year and 55.5% were female. The prevalence of malnutrition was 27.3%. A total of 30.8% were at risk of malnutrition, and 41.9% had a normal nutritional status. There were significant associations between nutritional status and chronic diseases, body mass index (BMI), mobility, psychological condition, mid-arm circumference (MAC), calf circumference, and more than three prescription drugs per day (P < 0.001).

A satisfactory nutritional status was found among most hospitalized elderly. Future studies with follow-up during and after hospitalization are required.

Polycystic ovary syndrome (PCOS) is with oxidative stress in women of reproductive age. Oxidative stress is an important factor in the development of insulin resistance. Some micronutrients are also linked to oxidative stress. The aim of this study was to determine the relationship between insulin resistance and micronutrient intake in PCOS subgroups.

This case-control study was performed on 151 PCOS. They were divided into four groups according to the Rotterdam diagnostic criteria: D = 37, C = 40, B = 33, A = 41 and 31 women were also in the control group and did not have this syndrome. Micronutrient food intake was assessed with a 168-item FFQ feed frequency questionnaire. Insulin resistance was diagnosed with HOMA-IR index (Cut off> 2.5). The data were analyzed with SPSS 22 using Kruskal Wallis (KW), Spearman, and Chi-square tests.

The mean age of participants was 28.53 years. There was a significant relationship between the HOMA-IR and some dietary components (selenium depletion in group A, zinc depletion, vitamin D, and vitamin E in group D, and vitamin D and vitamin E depletion in control group) (P < 0.05). There was no relationship between subgroups B and C.

Due to the significant relationship between insulin resistance indices, increasing the dietary intake of zinc, selenium, vitamin D, and vitamin E in women with PCOS, as well as increasing the dietary intake of these micronutrients in improving the physical health and fertility parameters of these people is recommended.

Maolasal is a honey-induced product which may lead to several beneficial effects from the Persian Medicine (PM) point of view. Heating process as a major step of Maolasal preparation may decrease the honey quality and deteriorate thermal treatment indicators of honey.

This study was conducted on four honey samples (from different floral sources). Maolasal preparation process was done according to one of the most important PM references “Gharabadin Kabir”. Thermal treatment indices, antibacterial and antioxidative activities of products were measured.

The 5-Hydroxymethylfurfural (HMF) concentrations of PM-based Maolasal samples of polyfloral, monofloral, and sugar honey were higher than 40 mg/kg; while PM-based Maolasal sample of monofloral honey had acceptable HMF concentration (38.9 mg/kg). Proline content of all samples decreased thorough Maolasal preparation and simple heating processes in all samples and these reductions were greater in monofloral honey and sugar honey Maolasal samples.  Maolasal preparation processes decreased diastase activity of all samples. Although Maolasal preparation process led to sucrose content reduction in the three Maolasal samples, sucrose content of Maolasal sample of monofloral honey was higher than its raw sample. Maolasal preparation process increased total phenolic content of all samples. Finally, Maolasal preparation process led to an increase in antibacterial and antioxidant activities of all the samples.

Maolasal samples reduced diastasis activity and proline content and increased HMF concentration. Maolasal preparation process may lead to an increase in antibacterial and antioxidative activities of honey which may be helpful for special preventive/therapeutic medicinal objectives.

  Nitrite and nitrate salts are used as preservatives in meat products to prevent the growth of pathogen organisms such as Clostridium botulinum. Nitrogen salts additives create the desired color in meat products. However, the use of these salts accelerates nitrosamine production and increases the risk of carcinogenesis. Hence, nitrate and nitrite consumption rate should be according to the approved standards. This analytical study is designed to determine nitrate and nitrite residue of non-heat-treated meat products including hamburger and kebab in East Azerbaijan Province, Iran during 2015-2020.

120 samples of non-heat-treated meat products from different brands were randomly collected. They consisted of 60 products manufactured in East Azerbaijan province and 60 products imported from other provinces.  Nitrate and Nitrite residues in non-heat-treated meat products including hamburger and kebab were determined by spectrophotometric method.

Results showed that the residue levels of nitrate and nitrite content regarding non-heat- treated meat products were less than maximum residual limits (MRLs) of national standards. The study also indicated that frozen non-heated meat products did not have any nitrogenous additive.

The results of this research revealed that the frozen non-heat treated meat products including hamburger and kebab, produced or consumed in East Azerbaijan province during 2015-2020 did not have nitrate and nitrite additives. Continuous monitoring to ensure the compliance of meat products with the standards is necessary.

The incidence of osteoarthritis (OA) is high in patients suffering from 25-hydroxyvitamin D3 (25(OH)D) deficiency. The goal of this study is to examine the association between saliva and serum 25(OH)D and knee OA.

Serum and saliva 25(OH)D levels of 30 patients with knee OA and 30 matched healthy people in a control group were measured by ELISA. Knee pain was assessed by Western Ontario and McMaster Universities Arthritis Index (WOMAC). Data were analyzed through student’s t-test, Pearson correlation test and receiver operating characteristic (ROC).

The mean serum and saliva 25(OH)D levels were lower in knee OA group than the healthy group. WOMAC negatively correlated with serum (r = -0.37; P = 0.02) and with unstimulated (r = -0.30; P = 0.04) saliva 25(OH)D. The unstimulated saliva 25(OH)D cutoff value was 27.8 pg/m1 regarding the diagnosis of knee OA.

Serum 25(OH)D levels were positively associated with saliva 25(OH)D, and 25(OH)D level in saliva, as in serum, was low in knee OA.

Foodborne diseases are caused by eating contaminated food. Yersinia species are among the bacteria involved in food contamination, such as meat, poultry, vegetables, and milk. This study aims to investigate the prevalence and characteristics of Yersinia enterocolitica and Yersinia pseudotuberculosis from raw milk in Tehran.

In this study, 360 samples of raw milk were collected from farms around Tehran and examined according to the FDA method. Then, 25 ml of milk samples were added to 225 ml of Peptone Sorbitol Bile Broth and kept for 10 days at 4 °C for enrichment. After 10 days, 0.5 ml of the sample was added to 0.5 ml of 0.72% KOH solution and 0.54% NaCl. After 30 sec, it was cultured in the selected Cefsulodin-Irgasan-Novobiocin agar (CINagar) medium to remove the normal flora. The plates were stored for 48 h at 28 °C. The suspected Bull's eye colonies were purified and phenotyping tests were carried out on the selected colony. The 20 E API kits were used for confirming identification.

From 360 raw milk samples, 4 Yersinia isolates (1.1%) including one Y. pseudotuberculosis (0.27%) and three Y. enterocolitica (0.83%) were isolated. In addition to Yersinia, other bacteria such as Klebsiella, Serratia, Citrobacter, and Providencia were isolated from milk samples.

The findings showed that clean tap water and healthy cattle in livestock can be effective in preventing Yersinia contamination. Lack of personal and environmental hygiene could cause food contamination by Yersinia and other intestinal bacteria leading to gastrointestinal infections.

Preeclampsia is a serious hypertensive condition of pregnancy associated with high maternal and fetal morbidity and mortality. In this study, the effect of selenium supplementation on the incidence and severity of preeclampsia in pregnant women was evaluated.

The present double-blind, placebo-controlled, parallel study was registered at Fatemieh Hospital of Hamadan, Iran. One hundred eighty women in the first trimesters of pregnancy were assigned to either selenium (SG, n = 90) or placebo (PG, n = 90) groups. SG and PG received 100 μg of selenium supplement or placebo per day, respectively.

In this study, no significant difference was observed between two groups in terms of age, body mass index, and serum selenium before the intervention (P > 0.05). The incidence of preeclampsia in the SG and PG was 9 and 5, respectively (P = 0.28). There was no statistically significant difference between sex and Apgar score of neonates in the two groups (P = 0.73). The mean birth weight, systolic and diastolic blood pressure in the SG was significantly higher than PG (P = 0.003, 0.01, and 0.007, respectively). The mean gestational age in the SG was insignificantly lower than the PG (P = 0.41). After the study, preeclampsia incidence was not significant between the groups (P = 0.28).

The administration of 100 μg of selenium supplementation in pregnant women, had no effect on decreasing preeclampsia, but it may reduce the severity of preeclampsia.

The relation between long-term dietary intake and diseases is well known. There are several methods to determine long-term dietary intake. The food frequency questionnaire (FFQ) is used in studies to assess habitual dietary intake over a long term period. Dietary intake varies according to cultural differences, so an FFQ must be designed and validated for the target population. This protocol study aims to explain the development and validation of a semi-quantitative FFQ for the Iranian population that includes mixed dishes and single food items.

The initial list of food items were extracted from interviews and expert opinion. An expert panel of ten nutritionists calculated the content validity ratio (CVR) and content validity index (CVI) of food items to finalize the FFQ. One hundred twenty eligible participants were included in the study. They completed the FFQ two times, with a ten month interval. They recorded their food intake for three days in the 2nd and 10th months of the study. In the 4th and 10th months, serum retinol and alpha-tocopherol, and 24-hour urinary potassium and nitrogen were measured.

Covering typical Iranian mixed dishes is the main advantage of this study. Given that the questionnaire is valid and reproducible, it can be used in epidemiologic studies.

The current study developed a dish-based Iranian FFQ based on mixed food.

A balanced-diet containing edible-oil has been advocated to have more of unsaturated fatty acid. The saturated nature of palm-oil (PO) has led to the recommendation that its consumption should be limited to avoid the risk of cardiovascular diseases (CVD). The purpose of this study was to investigate the claims and counterclaims of PO consumption and the risk of CVD from biochemical perspective.

Relevant published peer-review articles on PO consumption associated with risk of CVD were sorted from Google Scholar, Scopus, Medline, and PubMed databases. Keywords, such as “palm-oil, cardiovascular diseases, and cholesterol” were used for the search.

Apparent in animal studies, 52.17% support the claim that PO consumption is associated with CVD, and has been attributed to its saturated nature. According to the reports, PO consumption by virtue of its saturated nature-elicited hypercholesterolaemia, which may result to CVD. Furthermore, PO consumption may instigate fatty liver, cause narrowing blood vessels and thickening aorta of the heart, and consequently non-alcoholic steatohepatitis, a serious condition that may lead to severe cirrhosis, thereby increase CVD risk. On the other hand, 47.83% refute such claims that PO consumption is not associated with CVD risk. Based on human studies, 45.45% and 54.55% support and refute, respectively the claims that PO is associated with CVD.

PO consumption has shown to be associated with hypercholesterolaemia, elevated low density lipoprotein cholesterol, hence, could instigate CVD, even though no study convincingly establishes any relationship between PO consumption and the risk of CVD. Furthermore, consumption of repeatedly heated PO (deep-frying) may instigate oxidative stress, and consequently CVD.
