Obesity is related to increase in the incidence of morbidity and mortality. Previous studies have led to conflicting results regarding the effect of coenzyme Q10 (CoQ10) supplementation on anthropometric indices. This study aimed to evaluate the efficacy of CoQ10 supplementation on body weight, body mass index (BMI), and waist circumference (WC) through a systematic review and meta‑analysis of randomized controlled trials (RCTs).

PubMed, Scopus, Web of Science, and Cochrane Library as well as the reference lists of the identified relevant RCTs were searched up to March 2019, and weighted mean differences (WMDs) were pooled by using the random‑effects model.

Twenty RCTs (976 participants) were eligible to be included in the systematic review. The meta‑analysis revealed that CoQ10 supplementation had no effect on body weight (WMD = −0.04 kg; 95% confidence interval [CI]: −1.96, 1.6; I2 = 0.0%), BMI (WMD = −0.06 kg/m2 ; 95% CI: −0.54, 0.42; I2 = 0.0%), and WC (WMD = 0.79 cm; 95% CI: −2.83, 0.04; I2 = 0.0%).

CoQ10 supplementation might not improve anthropometric indices. Future well‑designed trials are still needed to confirm these results.

India was the first country in the world to launch a family planning programme, as early as 1952, with the main aim of controlling its population. India’s population has already reached 1.26 billion and considering the high decadal growth rate of 17.64, the country’s population is slated to surpass that of China by 2028.

The popularity of the internet aggravated by its excessive and uncontrolled use has resulted in psychological impairment or addiction. Internet addiction is hypothesized as an impulse‑control disorder of internet use having detrimental impacts on daily life functions, family relationships, and emotional stability. The goal of this review is to provide an exhaustive overview of the empirical evidence on internet addiction and draw attention to future research themes.

We performed a literature search on ScienceDirect and PubMed to review original research articles with empirical evidence published on peer‑reviewed international journals from 2010 to 2019. Eight hundred and 26 articles were eligible for analysis. Frequency and descriptive statistics were calculated by Microsoft Excel.

A substantial contribution has been coming from researchers from China, Turkey, Korea, Germany, and Taiwan respectively. Despite controversies regarding its definition and diagnostic procedures, internet addiction has become the focal point of a myriad of studies that investigated this particular phenomenon from different exposures. Given observed literature review data regarding research design, data acquisition, and data analysis strategies, we proposed the 3C paradigm which emphasizes the necessity of research incorporating cross‑disciplinary investigation conducted on cross‑cultural settings with conscientious cross‑validation considerations to gain a better comprehension of internet addiction.

The findings of the present literature review will serve both academics and practitioners to develop new solutions for better characterize internet addiction.

The possibility of getting cancer is affected by many factors, including age, lifestyle, weight, environmental factors, and family history and genetic predisposition. Some things cannot be controlled.

To plan for decreasing the prevalence of malnutrition among children, reliable data of current status are required. The aim of the present cross‑sectional study was to estimate the prevalence and trend of malnutrition among Iranian children.

PubMed, ISI Web of Science, Scopus, Google Scholar, and Iranian databases including SID and Magiran were searched for studies published prior to October 2017 with MeSH terms of Malnutrition, Nutrition Disorders, Wasting, Stunting, Underweight, Undernutrition, Nutrition, Anthropometry, Weight, and Children and Iran. Three random effect models were applied to estimate the pooled prevalence of underweight, stunting, and wasting. Meta‑regression and cumulative meta‑analysis were performed. All analyses were also conducted separately for two different age groups including 0–6 years old (preschool) and 7–11 years old (primary school). Seventy‑five studies (information of 1,069,815 individuals) were included in the final meta‑analysis.

The overall prevalence of underweight, stunting, and wasting was estimated to be 8.4% [95% confidence interval (CI): 7.6–9.1], 14.5% (95% CI: 13.1–15.9) and 5.6% (95% CI: 5–6.2) in children age 0–6 years, and 6.6% (95% CI: 4.8–8.4), 7.3% (95% CI: 5.6–9.1), and 8.3% (95% CI: 6–10.7) in children age 7–11 years, respectively.

The cumulative meta‑analysis showed a decrease in the general trend of malnutrition in both preschool and primary school children of Iran. Stunting and wasting were the most common form of malnutrition in Iranian preschool and primary school children, respectively. The decreasing trend of malnutrition was much more noticeable about stunting.

Hepatitis B virus is one of the transfusion transmissible infections. Despite the availability of hepatitis B virus (HBV) vaccine and screening tests but still danger of virus transmission via blood transfusion is high in some regions. The objective of this study was to determine the trend of seroprevalence of hepatitis B in over an 11‑year period (2005–2015).

In this study, 355,083 blood donors were estimated for hepatitis B surface antigen (HBs Ag) seropositivity during 2005–2015 who referred to blood infusion centers of Lorestan province. Third‑generation ELISA method was used to detect HBs Ag.

The prevalence of HBs Ag in blood donors was 0.29% (1017). It was decreased steadily from 2005 to 2015 (0.68% to 0.12%) but increased in 2008 year. The trend prevalence of HBs Ag seropositivity significantly decreased over the study period (P < 0.001). The decline in HBV infection rates was more prominent in regular and repeated donor’s groups compared to people who donated blood for the first time (P < 0.001).

The result of present study was indicated, Lorestan city in west of Iran can be classified as a low‑income region because the low prevalence of HBs Ag in blood donors. Also the prevalence of HBs Ag in first‑time donors was higher than other groups.

Oxidative stress and alteration of lipid profile due to obesity and overweight is a major risk factor for atherosclerotic plaque or coronary artery disease. Because of antioxidant and lipid lowering potential of saffron, this study investigated weight alteration, lipid profiles, and insulin resistance index in high‑calorie diet rats treated with aqueous extract of saffron stigma and petal.

Forty Sprague‑Dawley male rats were randomly divided into 8 groups including healthy control, high‑fat diet control, nicotinic acid treated, Anethum graveolens treated, and saffron stigma and petal treated groups. Rats received a high‑calorie diet for 16 weeks. For treatment, aqueous extract of saffron stigma (40 and 80 mg/kg) and petal (50 and 100 mg/kg) was used once daily for 4 weeks. Afterward, lipid profile, oxidative stress status, and insulin and adiponectin levels were measured using desired kits.

There was a significant decrease in the mean weight of the groups receiving saffron stigma and petal compared to control group (P < 0.05). The increased level of insulin hormone in obese group was improved in treated groups especially in the case of saffron stigma. Also, the decreased level of adiponectin was recovered in treated groups. An improvement was seen in oxidative stress markers and lipid profiles in treated groups compared to obesity pair.

In this study, a remarkable antioxidant and lipid lowering potential was detected for saffron stigma, which could improve insulin resistance in obese rats. Therapeutic and protective effect of saffron is mainly related to its richness in phenolic compounds. Saffron stigma compared with petal had more notable effect, which could and should be mentioned in pharmaceutical studies.

The hot line services were developed in response to the perceived need for 24‑hour help services in crises ranging from suicide to unwanted pregnancy. This study is aimed at analyzing the strengths, weaknesses, challenges, and suggestions of improving the performance of the help centers from the perspective of key stakeholders.

We conducted a qualitative study to elicit the key informants’ opinion regarding the performance of Iranian hot‑lines. All the conversations were audio‑recorded with the permission of the participants. To reach the saturation limit, the number of interviews was completed in the saturation of data. Data was gathered from 15 individual in‑depth interviews. Collecting and analyses of data was based on content analysis through which simultaneously during texts open coding, main concepts were extracted and then in axial coding similar concepts were categorized.

According to the study results, there is no specific and independent system for assessing the hot‑ lines. One of the major weaknesses was the lack of standard protocols. Most participants believed that most of these guidelines came from the general principles of counseling and are not standard. As another point, the existence of referral services is one of the main problems of counseling lines. The most important suggestion from the majority of experts were the development of services and modification of their investments.

The findings, in addition to providing the applied data for policy‑making in the health system, will significantly contribute to the creation of scientific, technical, and skillful personnel in the community of researchers.

Ferula asafoetida is introduced as a valuable remedy for hysteria and some other nervous disorders in Iranian traditional medicine. Asafoetida is an oleo‑gum‑resin obtained from the exudates of the roots of the Ferula asafoetida. Previous studies have shown that this oleo gum resin has antioxidant, anti‑apoptosis, and differentiation properties in the nervous system. The aim of this study was to evaluate the effect of asafoetida on the death of oligodendrocytes and demyelination in male C57BL/6 mice in cuprizone (CPZ)‑induced animal model of multiple sclerosis.

Demyelination was induced by oral administration of rats with the 0.2% CPZ that was added to the usual diet for 8 weeks. Animals intraperitoneally received daily asafoetida at doses of 25 or 50 mg/kg of bodyweight simultaneously.   At the end of the weeks, animal brains were removed and fixed to histological studies using Luxol fast blue staining. Asafoetida was screened for its antioxidant activity using 2, 2‑diphenyl‑1‑picrylhydrazyl free radical scavenging assay and for its inhibitory activity against lipid peroxidation catalyzed by soybean lipoxygenase.

The results of this study showed that asafoetida significantly decreased infiltration rate in both groups of asafoetida 25 and 50 mg/kg, respectively (P < 0.01). Histological evaluations showed the lower demyelination in LFB in the group treated with asafoetida.

The results of this study showed that asafoetida plays a neuro protective role in CPZ models of multiple sclerosis by reducing neuronal demyelination and oligodendrocytes death.

Food and nutrition literacy (FNL) is an emerging concept that emphasizes not only on personal knowledge, but food and nutrition skills about. This study aimed to develop and validate a food and nutrition literacy assessment tool (FNLAT) for youth and high‑school graduates in Iran.

The study protocol included the following steps: First, FNL components for Iranian high‑school graduates and youth were identified through literature review and interviews with experts. Delphi method was used in order to achieve consensus about FNL components. Then, the questionnaire items were generated, and its content and face validity were assessed. Construct validity of the questionnaire was evaluated through applying principal component analysis (PCA) and confirmatory factor analyses (CFA) in the next step. Finally, reliability of the FNLAT was assessed by calculating Cronbach’s Alpha and evaluating test‑retest reliability.

A 104‑item questionnaire was developed. S‑CVI was ≥90 which confirmed content validity of the questionnaire. PCA suggested that it was constructed of 6 factors, one in knowledge domain (food and nutrition knowledge) and five in skill domain (functional skills, interactive skills, advocacy, critical analysis of information, and food label reading skills). On the basis of CFA, the fit indices of the model had acceptable fit and confirmed construct validity of the FNLAT (X2 /df = 1.58, RMSEA = 0.041; P = 1.00, RMR = 0.034, GFI = 0.79). The values of Cronbach’s Alpha and intraclass correlation coefficient (ICC) confirmed internal consistency and time stability of the FNLAT and its subscales.

The developed FNLAT is a valid and reliable tool to assess FNL in Iranian late adolescents and youth.

Control of diabetes plays an important role in improving complications and disabilities and quality of life. This study aimed to evaluate the 3‑year changes in fasting blood glucose (FBG) values and its related factors in patients with type 2 diabetes.

In this retrospective cohort study, 500 patients with type 2 diabetes covered by the National Diabetic Prevention and Care Plan during 2013–2016 were selected based on random cluster systematic sampling. A linear mixed model was used to study changes in FBG levels and their related factors. The data were analyzed using the R3.2.0 software.

The patients’ mean age was 47.7 years. Among these patients, 58.6% were female, 19.8% had a history of smoking. High FBG was associated with high disease duration, high body mass index (BMI), low age, normal BMI at baseline, insulin therapy, smoking, and family history of diabetes. Trend of FBG in follow‑up was decreasing.

Given that patients who received insulin therapy had higher mean FBG, it is recommended to examine their insulin dose and modifications should be made in terms of the patients’ needs during their continuous follow‑up. Weight loss during follow‑up and cessation of smoking indicate a favorable prognosis of disease. More attention should be paid to younger patients in care. Patients are encouraged to start treatment and care at the same time diagnose.

The present study was conducted to evaluate the pattern of food preference among a large sample of Iranian adults.

In a cross‑sectional study within the study on the epidemiology of psychological alimentary health and nutrition (SEPAHAN) projects, a total of 6239 of 8694 subjects completed a 106‑item food preference questionnaire. Subjects indicated whether they liked, disliked or had gastrointestinal symptoms for each food item separately. They also reported the frequency of consumption for each food item.

We observed that presence of some foods such as yogurt, fruits and vegetables in the list of the most preferred food items and presence of kalbas, sausages and chips in the list of the most disliked food items, were representative of healthy dietary pattern in this population. Results also revealed that women liked unhealthy foods more than men (P value <0.05 for all significant food items). Moreover, in most of the food items, men reported less gastrointestinal symptoms than women (P value <0.05 for all significant food items). Our findings revealed that smokers disliked most of the healthy food items. We also observed that pregnant women regardless of the trimesters, reported dislike for sweet‑tasting food items.

More researches are suggested in order to indicate the origins of preferences and recommend some practical alternatives to improve the dietary pattern in society.
