Background: Appropriate management of fractures is crucial for restoring natural bone function and preventing long-term complications. Previous research on animal models indicates that trehalose can improve bone fracture healing by inhibiting the inflammatory cascade. We hope that trehalose can accelerate bone fracture healing in humans, alleviate pain, and ultimately enhance the individual's quality of life., Methods: This randomized, double-blind clinical trial will be conducted at Taleghani Hospital in Tehran, Iran. Sixty-four patients admitted to the orthopedic ward will be enrolled based on eligibility criteria. The participants will be randomly allocated based on the permuted block randomization into two groups: those receiving trehalose (32 patients) or placebo (32 patients). The patients in the trehalose and placebo groups will receive 3.3 g of trehalose or placebo for 12 weeks, respectively. A consent form, general questionnaire, as well as the Visual Analog Scale (VAS), Harris Hip Score (HHS), and radiological analyses will be used to assess fracture healing quality. The intention-to-treat principle will form the basis of the statistical analysis., Discussion: The trial results may provide a convenient and safe adjuvant treatment option for the Pertrochanteric Fractures population., Trial Registration: Iranian Registry of Clinical Trials.

Introduction: Peri-trochanteric fractures, common among the elderly with osteoporosis, pose significant morbidity and mortality risks. These fractures are increasing due to the ageing population, with Nordic countries seeing a high incidence. They present challenges for orthopaedic surgeons and can lead to functional decline and high medical costs. Hip fractures have severe consequences, including pain, immobility and increased mortality. Managing wound care is complex, involving various healing phases. Trehalose, a disaccharide with antioxidant and anti-inflammatory properties, has shown promise in wound healing and other health conditions. Studies suggest its potential benefits in reducing inflammation and aiding wound healing in peri-trochanteric fracture patients, but more research is needed to confirm its clinical effectiveness in humans., Methods and Analysis: The study is a double-blind, placebo-controlled randomised clinical trial aiming to evaluate the effect of trehalose consumption on patients with peri-trochanteric fractures. The study will include 64 patients meeting specific inclusion criteria and will assess inflammatory markers and wound healing at different time points. Patients will be divided into two groups, one receiving trehalose and the other receiving a placebo for 12 weeks. Various measurements and assessments will be conducted, including biochemical assays, wound assessments, anthropometric measurements and dietary intake evaluations. Data analysis will be performed using SPSS software, and statistical tests will be used to compare outcomes between the intervention and control groups., Ethics and Dissemination: The Ethics Committee of Shahid Beheshti University of Medical Sciences (IR.SBMU.RETECH.REC.1403.191)., Trial Registration Number: Iranian Registry of Clinical Trials.

Association between metabolic syndrome (MetS) and oxidative stress has been shown in numerous studies. It has been shown that probiotics could be the effective treatment strategy in improving oxidative stress. This study aimed to determine the effects of a new developed synbiotic yogurt on oxidative stress status in adults with MetS. Forty-four individuals were assigned into two groups and given 300 g of synbiotic yogurt containing Lactobacillus plantarum, Lactobacillus pentosus, and Chloromyces marcosianos yeast or regular yogurt for 12 weeks in this randomized, placebo-controlled clinical trial. Before and after the intervention, biochemical parameters were assessed. Daily consumption of synbiotic yogurt in adults with MetS showed a statistically significant improvement in the level of glutathione peroxidase (p = 0.01) and total oxidant status (p = 0.006) compared to the regular yogurt. Total Antioxidant Capacity and superoxide dismutase levels increased significantly (p = 0.002 and p = 0.02, respectively) in the intervention group compared to the baseline levels. In adults with MetS, daily consumption of the synbiotic yogurt containing native strains of Lactobacillus plantarum, Lactobacillus pentosus, and Chloromyces marcosianos yeast for 12 weeks was associated with improvements in oxidative stress status.Trial registration number: Iranian Registry of Clinical Trials (IRCT20220426054667N1) (18/05/2022)., (© 2024.

Several risk factors including environmental exposures, socioeconomic status, and dietary factors including dietary patterns have been considered for childhood Asthma. The present study tried to examine the association between a western-style pattern and the likelihood of asthma and its symptoms in Yazd, Iran. In the present cross-sectional study, dietary intakes of elementary and high-school children were obtained through a validated GAN questionnaire. The GAN questionnaire, derived from the ISAAC questionnaire was used to assess the symptoms of allergic diseases and their related risk factors. A western dietary pattern score considered 9 food groups including chicken eggs, margarine, butter, sugar, fast foods, soft drinks, snacks, sauce, and chocolate. In total 7667 children aged 10.9 ± 3.35 years were included in the current investigation. Boys with higher adherence to western dietary pattern had a higher risk of wheezing in the past 12 months (OR 1.37, 5% CI 1.01-1.87, P = 0.04) and this association was also observed in the whole population (OR 1.30, 5% CI 1.05-1.60, P = 0.01). However, after adjustment for confounders this relation did not remain significant in boys. Our results support the hypothesis that a western dietary pattern is associated with an increased risk of wheezing in the past 12 months in children with asthma. Future prospective studies are needed to confirm this finding., (© 2024. The Author(s).)

Diet quality in childhood and adolescence can affect health outcomes such as physical and cognitive growth and preventing chronic diseases in adulthood. This study aimed to evaluate the relationship between diet quality using the modified youth healthy eating index (MYHEI) with socioeconomic factors and nutrition status in 7-12-year-old children in Iran. This descriptive-cross-sectional study was performed on 580 students in Zabol, Iran, selected through multistage cluster sampling. The diet was assessed through the 168-item food frequency questionnaire (FFQ) and eating behaviors. Then, the MYHEI scoring system was used to calculate the diet quality. In addition, we used the WHO growth indices, such as weight to age, height to age, and body mass index (BMI) to age ratios, to evaluate nutrition status. The mean total MYHEI score in children was 56.3 ± 11.2. Among children with the highest MYHEI score quartile, the number of girls was significantly higher than boys (p = 0.001). The prevalence of underweight, stunting, and wasting was 25.3%, 17.4%, and 21.7%, respectively. The prevalence of underweight (OR: 2.2; 95% CI  1.26, 3.90, p = 0.001) and stunting (OR: 3.2; 95% CI   1.65, 6.14, p = 0.006) were significantly lower in the higher MYHEI score quartile compared to the lower quartile. The overall diet quality of most children should be modified. Therefore, to improve the children's health and nutrition status, it is necessary to perform nutritional interventions such as training and promotional programs, especially in schools., (© 2024.

Purpose: This study conducted in Dena County is a population-based cohort study as part of the Prospective Epidemiological Research Studies in Iran (PERSIAN). The specific objectives of this study were to estimate the prevalence of region-specific modifiable risk factors and their associations with the incidence of major non-communicable diseases (NCDs)., Participants: This PERSIAN Dena Cohort Study (PDCS) was conducted on 1561 men and 2069 women aged 35-70 years from October 2016 in Dena County, Kohgiluyeh and Boyer-Ahmad Province, Southwest Iran. The overall participation rate was 82.7%., Findings to Date: Out of 3630 participants, the mean age was 50.16 years, 2069 (56.9%) were women and 2092 (57.6%) were rural residents. Females exhibited higher prevalence rates of diabetes, hypertension, fatty liver, psychiatric disorders, thyroiditis, kidney stones, gallstones, rheumatic disease, chronic lung disease, depression and osteoporosis compared with males (p<0.05). Furthermore, the urban population showed elevated rates of diabetes, thyroiditis, kidney stones and epilepsy, whereas psychiatric disorders and lupus were more prevalent in rural areas (p<0.05). According to laboratory findings, 418 (13.0%), 1536 (48.1%) and 626 (19.3%) of the participants had fasting blood sugar >126 mg/dL, low-density lipoprotein >100 mg/dL and haematuria, respectively; most of them were female and urban people (p<0.05)., Future Plans: PDCS will be planned to re-evaluate NCD-related incidence, all-cause and cause-specific mortality every 5 years, along with annual follow-up for 15 years. Some examples of additional planned studies are evaluation of genetic, environmental risk, spirometry and ECG tests., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Metabolic syndrome (MetS) is one of the leading public health issues in the world with a reported prevalence of nearly 25% in the past decades in Iran. The present research aimed to identify the association between the Healthy Eating Index (HEI) and MetS components among female teachers., Methods: In this cross-sectional study, 97 female teachers aged 31-57 years were enrolled from 2018 to 2019 in Qom, Iran. Usual dietary intakes were assessed using a validated 168-item Food Frequency Questionnaire (FFQ). HEI-2015 was calculated according to the consumption of whole fruits, vegetables, protein foods, beans, seafood, plant proteins, total and refined grain, dairy, fatty acid ratio, saturated fats, added sugars, and sodium. We also measured anthropometric and biochemical parameters. To evaluate the association between HEI-2015 and MetS, multivariate logistic regression was performed., Results: MetS was found in 59.8% of participants. Total HEI-2015 scores were significantly lower in participants with MetS compared to those without MetS (59.69 ± 8.98 vs. 64.21 ± 8.71, respectively; p = 0.02). Daily energy intake, weight, body mass index, waist circumference, systolic and diastolic blood pressure, serum triglyceride, and fasting blood sugar levels were higher in women with MetS (all p < 0.05). Higher HEI-2015 total scores (OR: 0.94; 95% CI: 0.89-0.99; p = 0.02) and scores of total vegetables (OR: 0.62; 95% CI: 0.42-0.91; p = 0.02), dark green vegetables and beans (OR: 0.62; 95% CI: 0.39-0.98; p = 0.04), fatty acid ratio (OR: 0.83; 95% CI: 0.68-0.99; p = 0.04), refined grain (OR: 0.86; 95% CI: 0.75-0.99; p = 0.04), and added sugars (OR: 0.44; 95% CI: 0.26-0.75; p = 0.002) were all associated with lower odds of having MetS., Conclusions: Higher HEI-2015 scores, particularly in total vegetables, dark green vegetables, beans, and fatty acid ratio, as well as refined grain and added sugars were found to be associated with reduced odds of having MetS among Iranian female teachers. However, further prospective studies are required to confirm this finding., (© 2024. The Author(s).)

Background: Metabolic syndrome is recognized as one of the most common global health issues, which may cause numerous side effects. Studies have shown the favorable effects of probiotic supplements on glycemic indices, lipid profiles, and oxidative stress status. However, the number of studies investigating the effects of food products containing probiotics and prebiotics on metabolic diseases is limited. Limited evidence also shows that products containing Lactobacillus plantarum could affect metabolic alterations in chronic diseases. No previous study evaluated the impact of synbiotic yogurt containing Lactobacillus plantarum on people with metabolic syndrome. Therefore, the current study aims to investigate the effect of the newly developed synbiotic yogurt containing Lactobacillus plantarum, Lactobacillus pentosus, and Chloromyces marcosianos yeast on the components of metabolic syndrome, oxidative stress status, and some other risk factors for cardiovascular diseases in adults with metabolic syndrome., Methods: In this study, 44 patients with metabolic syndrome will be randomly assigned to intervention and control groups in a randomized, double-blind, controlled clinical trial. Participants in the intervention group will consume 300 g of synbiotic yogurt daily, while those in the control group will consume 300 g of regular yogurt daily for 12 weeks. Anthropometric measurements, blood pressure, and biochemical parameters will be evaluated before and after the intervention., Discussion: The management of the metabolic syndrome presents significant clinical challenges. While probiotic supplementation for these individuals has been considered, the consumption of probiotic-rich foods has received considerably less attention., Trial Registration Number: Iranian Registry of Clinical Trials (IRCT20220426054667N1) (2022-05-18)., (© 2023.

Phytochemicals are bioactive compounds found in plant-based foods. Consumption of phytochemical-rich foods has been associated with cardiovascular and metabolic diseases prevention in various populations. To quantify the phytochemical content of the diet, dietary phytochemical index (DPI) was established which is defined as the proportion of daily energy intake derived from foods rich in phytochemicals. The purpose of this study was to evaluate the association between the DPI and oxidative stress markers and cardiovascular risk factors in obese adults. In this cross-sectional study, a total of 140 adults aged 20-60 years and body mass index (BMI) of ≥ 30 kg/m 2 were included. A validated food frequency questionnaire (FFQ) was used to collect information on dietary intakes. The DPI was calculated based on the following formula: DPI = [daily energy obtained from foods rich in phytochemicals (kcal)/total daily energy intake (kcal) × 100]. There was an inverse association between DPI and serum concentrations of Malondialdehyde (MDA) (P = 0.004), triglyceride (TG) (P-trend = 0.003), high-sensitive C-reactive protein (hs-CRP) (P = 0.017), and erythrocyte superoxide dismutase (SOD) activity (P = 0.024). Total antioxidant capacity (TAC) was positively associated with DPI score (P = 0.045). No significant relationship was found between the DPI score and fasting blood sugar (FBS), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total oxidant status (TOS), glutathione peroxidase (GPx), catalase (CAT), and anthropometric parameters as well as systolic and diastolic blood pressure. The current study found that there was a significant inverse association between DPI and oxidative stress, inflammation, and hypertriglyceridemia as cardiovascular disease (CVD) risk factors in obese population. However, further research is needed to confirm these findings., (© 2023. The Author(s).)
