Background: Lipid disorder is a modifiable risk factor for diseases related to plaque formation in arteries such as heart attack, stroke, and peripheral vascular diseases. Identifying related factors and diagnosis and treatment in time reduces the incidence of non-communicable diseases (NCDs). The aim of this study was to determine factors associated with lipids based on a national survey data. Methods: Data of 16757 individuals aged 25–64 years obtained from the Iranian STEPwise approach to NCD risk factor surveillance (STEPs) performed in 2016, through multistage random sampling, were analyzed. Because of clustered, hierarchical, and skewed form of the data, factors related to total holesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol) (LDL-C), high-density lipoprotein-cholesterol) (HDL-C), TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C were determined applying multilevel quantile mixed model. Parameters of the model were estimated on the basis of random effect of the province as well as urban or rural area for 10^th, 25^th, 50^th, 75^th, and 90^th quantiles. Statistical analyses were performed by R software version 4.0.2. Results: Significant relationship was found between age, body mass index (BMI), waist circumference (WC), diabetes, hypertension, smoking, physical activity, education level, and marital status with TC, LDL-C, HDL-C, LDL-C, and LDL-C/HDL-C. With increasing BMI and WC, subjects had higher levels of serum lipids, especially in higher quantiles of lipid levels. Lipid levels were significantly increased among smokers and those with diabetes or hypertension. The random effects were also significant showing that there is a correlation between the level of lipids in provincial habitants as well as urban and rural areas. Conclusions: This study showed that the effect of each factor varies depending on the centiles of the lipids. Significant relationship was found between sociodemographic, behaviors, and anthropometric indices with lipid parameters.

Background: Diabetes has become an important health problem in the world. Natural agents, with antidiabetic property, are potential candidates for improving diabetes. Urtica Dioica Distillate (UDD) or Araghe Gazaneh is widely used for the treatment of diabetes as per traditional medicine. Despite the tremendous use of UDD as an antidiabetic compound in folk medicine, the antidiabetic effects of UDD has been neglected by medical scientists. In this study, we aimed to evaluate the effects of UDD on the glucose metabolism in diabetic rats. Methods: A total of 24 male rats were divided equally into four groups, two treatment and two control groups, each containing normal or Streptozotocin (STZ)–induced diabetic rats. During 4 weeks, control and treatment rats received water or UDD, respectively. Fasting blood sugar (FBS), HbA1c, serum creatinine, blood urea nitrogen, and specific activities of hepatic enzymes including glucokinase (GK), hexokinase (HK), glucose-6-phosphate dehydrogenase (G6PD), and muscle glucose transporter type 4 (GLUT4) and liver phosphoenolpyruvate carboxykinase (PEPCK) mRNA levels were measured. Results: FBS and HbA1c increased in diabetic groups. Treatment with UDD significantly lowered FBS and prevented weight loss. Decreased FBS level was associated with higher activity levels of GK and HK in UDD-treated diabetic rats. G6PD-specific activity decreased in diabetic control rats compared to nondiabetic ones, but UDD treatment improved it to the normal levels. A significant decrease in the expression level of GLUT4 was observed in diabetic control rats compared to nondiabetic ones, but UDD increased it to the normal levels. Conclusions: These findings suggest that UDD might exert therapeutic effects against diabetes by improving glucose metabolism and can be used as an alternative or complementary medicine for the treatment of diabetic patients.

Background: Both aging and diabetes are two well-established risk factors related to type 3 diabetes and memory deficits. Accordingly, diabetes multiplies the effects of aging on cognition impairments once these conditions occur simultaneously. Methods: In this present experimental study, 56 male Wistar rats with HFD/STZ-induced T2D were randomized into seven groups (n = eight animals per group): (1) sedentary old non-diabetic (C); (2) sedentary HFD/STZ-induced T2D (D); (3) sedentary HFD/STZ-induced T2D plus UA (UA) (DU); (4) endurance-trained HFD/STZ-induced T2D (DE); (5) resistance-trained HFD/STZ-induced T2D (DR); (6) endurance-trained HFD/STZ-induced T2D plus UA (DEU); and (7) resistance-trained STZ-diabetic plus UA (DRU) rats. Two-way ANOVA was applied to measure the training, supplementation, and interaction effect on serum and gene expression outcomes. Result: The study results established no significant interaction effect between the UA supplementation and the resistance/endurance training with regard to the levels of glucose (P = 0.534), insulin (P = 0.327), brain-derived neurotrophic factor (P = 0.191), and insulin-like growth factor-1 (P = 0.448). Conclusions: To develop novel practical nutritional strategies involving UA intake, further studies are thus needed to clarify how chronic consumption of UA with/without resistance/endurance training reverses cognition disorder process in old male Wistar rats with HFD/STZ-induced T2D.

Introduction: Food waste reflects inadequate food intake and is of economic and environmental importance. Therefore, understanding the underlying factors is a must to combat food waste. Methods: A qualitative study was conducted using semi-structured interviews with managers, nurses, nutritionists, food providers, kitchen staff, and inpatients at three hospitals in Tehran. Responses were recorded, coded, and analyzed thematically. Results: Forty-eight face-to-face interviews led to three core categories: 1. opinions/performance; 2. causes, related factors, and characteristics; and 3. rooting and suggestions. We found that the majority of the hospitalized patients did not consume their entire food. In spite of overall satisfaction with the quantity and quality of food, anorexia, personal taste, and poor quality of raw materials prohibited patients from eating. Also, rice was the most discarded food. Economic barriers were the most important hindrance to elevate the quality, and some strategies, like the supply of high-quality materials and recruiting skillful cooking team, were proposed to improve it. Conclusions: Our findings delineated a limited budget as the main barrier to improve the quality. Nevertheless, the low quality of hospital foods may actually impose a heavier economic burden due to food waste.

Background: The alteration of DNA cytosine methylation is one of the most common epigenetic changes that can play a significant role in human cancers. The enzymes involved in DNA methylation of promoter regions of the genes are DNA methyltransferases (DNMTs). The therapeutic activities and apoptotic effects of DNA methyltransferase inhibitors (DNMTIs) have been reported in various cancers. This study was assigned to assess the effect of zebularine on intrinsic and extrinsic pathways, DNAT 1, 3a, and 3b, p21, and p53, viability, and apoptosis in hepatocellular carcinoma (HCC) cell lines. Methods: Hepatocellular carcinoma cell lines (HCCLM3, MHCC97H, and MHCC97L) were purchased from the National Cell Bank of Iran, Pasteur Institute, treated with zebularine, and the MTT assay was performed. Then, flow cytometry assay and real-time RT-PCR analysis were performed with zebularine. Statistical comparisons between groups were made using GraphPad Prism software version 8.0. A significant difference was considered as P < 0.05. Results: Zebularine up-regulated DR4, DR5, FAS, FAS-L, TRAIL, Bax, Bak, Bim, p21WAF/CIP1 (p21), and p53 and down-regulated DNMTs (DNAT 1, 3a, and 3b), Bcl-2, Bcl-xL, and Mcl-1, significantly resulting in apoptosis induction in HCC cell lines. Maximal and minimal apoptosis was seen in HCCLM3 and MHCC97L cell lines, respectively. Conclusions: Our findings indicated that DNMTI zebularine can induce apoptosis and inhibit cell growth through both pathways (extrinsic and intrinsic) in HCC cell lines HCCLM3, MHCC97H, and MHCC97L.

Background: Cardiovascular diseases (CVDs) are recognized as one of the leading causes of death worldwide. Studies have shown the impact of genetic predisposition and dietary factors on developing these diseases. Dietary patterns and genetic factors such as polymorphisms related to the level of adiponectin may also interact with each other and produce variances in the effects of these factors on different individuals. The purpose of this study is to investigate the interactions between food intake patterns and polymorphisms on ADIPOQ and ARL15 genes in relation to cardiometabolic risk factors. Methods: This cross-sectional study is conducted on 380 adults (20 to 70 years old) living in Yazd, Iran. Individuals were selected from the participants in Yazd Health Study (YaHS) and its sub-study called Taghziyeh Mardom-e Yazd (TAMYZ) after reviewing the inclusion and exclusion criteria. YaHS is a population-based cohort study which has been conducted on 9962 adults living in Yazd since 2014. In the present study, rotated principle component analysis (PCA) with Varimax rotation is used to identify the major dietary patterns. The polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) method is used in order to identify rs1501299 and rs6450176 variants (on ADIPOQ and ARL15 genes, respectively). General linear models (GLM) as well as regression models are used to investigate the interactions between the studied genotypes and the extracted dietary patterns. Conclusions: The results of this study can help to personalize dietary recommendations for the prevention of CVDs according to the genetic predisposition of individuals.

Background: Diclofenac (DIC) is an NSAID that can cause toxic effects in animals and humans and carvacrol (CAR) is a monoterpene compound that displays effective pharmacological and biological actions. The purpose of this work was to assess the influences of CAR on DIC-induced liver injury and oxidative stress in male rats. Methods: The male Wistar rats were segregated into four groups. Group 1, the control group; Group 2 received DIC-only (10 mg/kg BW, p.o); Group 3, received CAR-only (10 mg/kg BW, p.o), and group 4 received DIC plus CAR. The serum levels as well as the activity of several liver-associated markers, and oxidative and anti-oxidant compounds were tested. The expression of pro-inflammatory mediators was also studied using the qRT-PCR analysis. Results: Our results showed that DIC treatment was associated with the elevation in the serum levels of liver-related markers together with the increase in the serum and the hepatic levels of malondialdehyde (MDA) and protein carbonyl (PC). Moreover, DIC reduced the activity of the antioxidant system in the rats and increased lymphocyte infiltration into the hepatocytes. CAR; however, protected the hepatocytes from the toxic effects of DIC by enhancing the activity of antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and Glutathione (GSH). By diminishing the expression of tumor necrosis factor (TNF)-α, CAR was also capable of preventing the inflammatory effects of DIC on liver cells. Conclusions: The findings of this study indicated that the administration of CAR could alleviate the noxious effects of DIC on the antioxidant defense system and liver tissue.

Background: Equitable distribution of health care sector resources is one of the most important goals of health systems in all countries. The purpose of this study is to measure equity of geographical distribution of active specialist physicians in Iran's health system. Methods: The present study was a descriptive-cross-sectional. The statistical population included: all active specialist physicians working in the public, private, social insurance organization, military, charity, and the other health service providers in Iran in 2019. Studied demographic data were collected from Iran's national statistic center. Also, information of specialist physicians was obtained from several databases. Finally, duplicated records were removed, and the number of specialist physicians extracted. Data analysis was performed using Stata V.16 and ArcGIS 10.4 software. Results: The results showed that the number of specialist physicians per 100,000 population who worked in Iran's health system was 46.81. The provinces of Tehran had the highest and Sistan and Baluchestan had the lowest number of specialist physicians. Also, 52.63% of active specialist physicians provide health services in four provinces, whereas these provinces are 37.13% of the country's population. Total Gini coefficient of the distribution of active physicians in Iran in 2019 was 0.23. Conclusions: Distribution of specialist physician was different but somewhat equitable in the provinces. However, in some provinces, the ratio of specialist physicians to the population was still low. Therefore, when the number of specialist physicians increased, their distribution should be considered concurrently.

Background: One of the most effective strategies to improve the access of community members to health services is to regionalize health services. The purpose of this study is to examine and prioritize measures that could help to counteract obstacles and problems in implementing the regionalization of healthcare in Iran. Methods: The study relied on a mixed research method, including qualitative and quantitative phases. First, by conducting semi-structured interviews and analyzing them through qualitative content analysis, the obstacles and measures were identified. In the quantitative phase, the obstacles identified were weighted using the fuzzy best-worst method (FBWM), and the measures were then prioritized through the fuzzy TOPSIS (FTOPSIS) method. Results: The obstacles were categorized into four main dimensions: “infrastructural,” “political,” “human resources,” and “managerial.” Among the 15 obstacles identified, “absence of performance guarantees” was the most important obstacle, while “insufficient education” was the least important obstacle to the regionalization of healthcare services in Iran. Meanwhile, the following eight measures that could help to overcome the obstacles were extracted from the interviews: “conducting a needs assessment,” “providing clinical guidelines,” “employing specialized human resources,” “reinforcing the referral system,” and “preparing electronic health records,” “enhancing education and information dissimilation,” “building executive support,” and “providing cost-effective equipment and technology.” “Employing specialized human resources” was also the most effective measure to overcome the obstacles. Conclusions: Iranian healthcare policy-makers can use the empirical findings of this investigation to accelerate the implementation of Iran's regionalization plan to improve the access of community members to healthcare services.

Background: This study is to determine the effect of the family-centered intervention (FCIS) on the key indicators of diabetes management and Control control in patients with type-2 diabetes. Method: The present study is a quiz- experimental study with a randomized control group. Participants were 64 patients with type-2 diabetes visiting Ali Asghar Hospital of Isfahan in 2018. The eligible patients were assigned to either the intervention group or the control group (i.e., patient-center care) through block randomization. FCIS were implemented in 4 two-hour sessions as home visits while the patients and their caregivers were present. Data were collected twice-i.e. before the intervention and 12 weeks after it- and were analyzed, by running a t-test (α = 0.05), using SPSS-21. Results: The mean ± SD age of participants was 50.4 ± 8.5. There was no significant difference between the two groups in the mean weight, serum levels of FBS and A1C, physical activity, energy intake, and BMI before intervention. But, a significant improvement in the mean values of these variables in the intervention group after the intervention, compared with the control group was indicated (P < 0.05). Conclusions: This study suggests that FCIS are more effective than patient-center care in the management and control of type-2 diabetes. Therefore, it is recommended that the family be considered in educational interventions.

Introduction: The COVID-19 pandemic has created several challenges for countries all over the world. Different countries have taken different measures to fight this pandemic and reduce its challenges depending on their cultural, economic, and social structures. This study aims to understand and explain the Iranian health system's response to fighting the COVID-19 pandemic from the managers' and authorities' perspective. Method: This study is a basic applied research performed under a qualitative approach. In the survey, 30 experts including the managers of health centers and deputies and heads of the Ministry of Health and Medical Education and Medical Universities were selected by purposive snowball sampling and participated in semi-structured interviews from March to May 2020. The researchers explained the actions of the Iranian health system in fighting the COVID-19 pandemic in 2020 by content analysis. Results: As a result, 14 subthemes were found and classified into four major themes, including the informative and regulative actions (two subthemes), administrative and supportive actions (six subthemes), preventive and curative actions (three subthemes), and resource-related actions (three subthemes). Conclusions: Due to its strong health structures, such as urban and rural health networks, various general and specialized hospitals, experienced doctors, and committed health staff, Iran has taken practical actions in fighting the COVID-19 pandemic. However, the findings of this study and its relevant measures can help combat this pandemic in countries with similar social and cultural structures or counter future similar crises.

Background: Hematological inflammatory indices are currently suggested to assess systemic inflammation. This study aims to investigate a vitamin D supplementation effect on hematological indices of inflammation in rats. Method: Forty-eight middle-aged male rats were allocated into a normal diet (ND) group (10% fat) and a high-fat diet (HFD) group (60% fat). The animals were fed for 26 weeks. After this period, each group was randomly divided into three subgroups, each of 8 rats: Group (1): animals were fed the ND and HFD containing 1 IU/g vitamin D for 4 months, group (2): animals were fed the ND and HFD containing 6 IU/g vitamin D for 4 months and group (3): animals were euthanized to evaluate the HFD effect. Serum 25-hydroxyvitamin D level, white blood cell count (WBCs), platelet count, platelet crit (PCT), mean platelet volume (MPV), platelet distribution width (PDW), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) were measured. Results: The HFD, significantly increased body weight, PCT, PDW, PLR, NLR, and MLR and significantly reduced serum vitamin D levels compared to the ND (P < 0.05). There was a significant decrease in food intake, MPV, PDW, and NLR after vitamin D supplementation in the ND-fed group (P < 0.05). A significant reduction in platelet count, PCT, and MLR was observed after vitamin D supplementation in HFD-fed rats (P < 0.05). Conclusions: In our study, some hemogram-derived inflammatory indices were higher in the HFD-fed group, and vitamin D supplementation lowering effects on some hematological indices were seen in both ND and HFD groups.

Background: Several animal studies have shown the protective effect of silymarin (the extract of Silybum marianum seeds) against anti-tuberculosis drug-induced hepatotoxicity (ATDH). However, the knowledge of ATDH of silymarin in humans is scarce. In this study, we aimed to clinically evaluate it. Methods: During this randomized controlled clinical trial, 36 new cases of tuberculosis (TB) were enrolled to receive either silymarin 150 mg twice daily for two weeks along with a standard anti-TB therapeutic regimen (experimental group; n = 16) or standard anti-TB therapeutic regimen alone (control group; n = 21). Liver function tests (serum AST, ALT, ALP, and total bilirubin) at the end of weeks 1 and 2 as well as the rate of ATDH during the study were determined and compared between the groups. Results: No significant differences between the experimental and control groups were observed at the end of the first week regarding liver function tests; However, at the end of the second week, the mean serum levels of AST (P = 0.03) and ALP (P = 0.04) were significantly lower in the experimental group. ALT (P = 0.016) and ALP (P = 0.027) levels in the experimental group significantly decreased during the study, while the changes in the control group were not significant. Two patients in the control group (9.5%) developed ATDH, while no one in the experimental group manifested this adverse effect. Conclusions: Our study suggests that silymarin use has the potential for the reduction of anti-TB drug-induced hepatotoxicity.

Background: Sodium arsenate (Na 3As0 4, Sodium As) is an important toxic substance that leads to nephrotoxicity. Due to having bioactive molecules, such as polyphenols and tyrosol, olive oil plays a significant role in scavenging free radicals. This study aimed to investigate the effects of olive oil and tyrosol on As-induced nephrotoxicity. Methods: In our study, 42 adult male BALB/c mice were randomly divided into six groups: control (normal saline), olive oil (0.4 ml/d, gavage), tyrosol (5 mg/kg/d), Sodium As (15 mg/kg), olive oil + Sodium As, and tyrosol + Sodium As (olive oil and tyrosol received one hour before Sodium As). Drugs were administreted once daily for 30 consecutive days. On the 31^st day of the study, oxidative stress parameters in kidney tissue, FRAP in plasma, renal function parameters in serum, and histopathological assays were performed. Results: Sodium As-induced renal damage as characterized by a significant increase of creatinine and BUN (P < 0.001) and histopathological changes. Also, Sodium As markedly altered oxidative stress biomarkers such as a significant increase in MDA (P < 0.001) and significantly decreased in FRAP and GSH (P < 0.01). Olive oil and tyrosol administration significantly improved the renal antioxidant defense system and decreased MDA concentration, markedly preserving the tissue structure and functional markers of kidney. However, these effects were more effective for tyrosol than olive oil. Conclusions: Our results suggest that olive oil and tyrosol can be used as a protective agent in preventing Sodium As-induced nephrotoxicity due to antioxidant property.

Background: Ulcerative colitis is one of the major phenotypic forms of inflammatory bowel diseases. The present study aimed to investigate the effect of force swimming exercise on clinical symptoms (disease activity index; DAI), colon histopathology, inflammation and fibrosis, and oxidant/antioxidant balance in dextran sulfate sodium (DSS)-induced colitis mice. Methods: Male C57BL6 mice were randomly divided into five groups (n = 6 each): control, exercise, colitis, colitis + sulfasalazine, and colitis + exercise. Exercise was performed by forced swimming six weeks before and during the experiment. Colitis was induced by 1.5% DSS in drinking water. The animals were evaluated for body weight changes and DAI (including changes of body weight, stool consistency, rectal bleeding, and prolapse) during the induction of colitis and treatment. At the end of experiment, colons and spleens were evaluated by H and E and Masson Trichrome stainings. Oxidant (Malon dialdehyde; MDA), and antioxidant markers [total thiol groups, superoxide dismutase (SOD), and catalase activity] were also measured in colon tissue. Results: Results indicated that exercise in colitis mice significantly improved DAI, colon length, spleen weight, and histological injury score and alleviated fibrotic changes in colon tissue that were comparable to sulfasalazine group. Exercise also restored the oxidant/antioxidant balance in colitis mice by reducing MDA and increasing antioxidative markers including total thiol groups, SOD, and catalase activity. Conclusions: Taken together, aerobic exercise could improve clinical symptoms and colonic inflammation through, at least, the balancing the oxidative stress markers. Thus, it can be considered in management of colitis patients as effective method.

Background: In the present study, we investigated the effect of two doses of atropine eye drops versus placebo on myopia progression in children and adolescents. Methods: In this double-blind, randomized clinical trial, 67 patients aged 6 to 18 years with myopia of -2 to -6 D were enrolled and randomized to receive a placebo eye drop, atropine 0.1%, or 0.01% ophthalmic solution (one drop per night for 6 months). All participants were followed-up with for one year after the beginning of the study (at zero, one, three, six, and 12 months) and their spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), and far and near visual acuity (VA) and the eye drops side effects were recorded. A comparison among the groups was performed using SPSS software, version 24.0. Results: Spherical equivalent, AL, and ACD decreased and far VA improved in atropine groups to a greater extent than the placebo group (P < .05) at the 6-month follow-up. The most common side effects of atropine 0.1% eye drop included photophobia and decreased near VA. At the end of the study (six months after the cessation of atropine), a rebound effect was observed; this effect was especially severe in the 0.1% atropine group. Conclusions: Atropine eye drops are effective for slowing down and preventing myopia progression. However, without long-term treatment, they will have a rebound effect. A lower dose (0.01%) is suggested for reducing the side effects and rebound effects.

Background: This study aimed at evaluating the accuracy of the pediatric appendicitis scoring method in differentiating nonspecific abdominal pain (NSAP) from appendicitis. Methods: This cross-sectional study was conducted on 391 children who were hospitalized in the emergency ward due to acute abdominal pain suspected of appendicitis . Pediatric Appendicitis Score (PAS), C-reactive protein (CRP), and appendicitis pathology results of patients undergoing surgery were recorded. Results: The results showed that the no significant difference was found among patients in the three experimental groups (appendicitis, specific abdominal pain except appendicitis, and NSAP) with respect to temperature (p = 0.212), but the other variables were significantly different. Findings showed that high CRP frequency, pain migration to right lower quadrant (RLQ), tenderness in right iliac fossa (RIF), anorexia, leukocytosis, high neutrophil, and mean tenderness in RLQ in the appendicitis group were higher than those in the other two groups (p = 0.001). The PAS questionnaire can also be used as a reliable questionnaire with appropriate sensitivity (0.929) and specificity (0.993), and this questionnaire along with detailed clinical examinations could reduce the rate of negative appendectomy to less than 1%. Conclusions: This study showed high accuracy of PAS in diagnosing children with appendicitis and differentiating appendicitis from cases of NSAP and specific abdominal pain other than appendicitis. The PAS system could also significantly reduce cases of negative appendicitis. Although high CRP had an excellent ability to diagnose appendicitis, its accuracy was lower than PAS.

Introduction: COVID-19 is a respiratory disease caused by infection with severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2). Thrombotic complications appear to be of particular importance in patients with COVID-19. This study aimed to investigate Changes in the level of Antiphospholipid antibodies (Anticardiolipin and Anti-β2-glycoprotein-I) and thromboembolic indices in COVID-19 patients during 3 weeks. Methods: This cross-sectional study was performed on adults with Covid-19 hospitalized at Al-Zahra Hospital in Isfahan. The case group includes the patients admitted to the internal ward or ICU who despite receiving prophylactic or anticoagulant doses suffer from thrombotic complications and the control group includes COVID-19 patients without thromboembolic events. The sample size of 120 people was considered. Anticardiolipin and anti-β2-glycoprotein-I antibodies, coagulation profiles including Fibrinogen, PTT, PT Troponin, ESR, CRP, and D-dimer were examined. After collection, the data were entered into spss24 software and analyzed. Results: The results showed that there was no statistically significant difference in the changes of anticardiolipin and anti-beta-2 glycoprotein in IgM and IgG as well as in the changes of ESR, CRP, PTT, PT, and fibrinogen in the two groups (P > 0.05). Conclusions: Our study showed that there was no statistically significant relationship between anti-phospholipid antibodies (anticardiolipin and anti-beta-2 glycoprotein) and thromboembolic events. Therefore anticardiolipin and anti-beta-2 glycoprotein is probably the puzzles causing thrombosis in COVID-19 patients, and other inflammatory responses should be examined among the cases.

Background: Eye health is essential for quality-of-life. The present study aimed to design an eye care behaviors assessment instrument for the student community and evaluate its psychometric properties. Methods: The present mixed-method cross-sectional study was conducted in two sections using Creswell and Plano Clark methods for instrument development. The study was conducted in Isfahan, Iran, in 2021. The first section (textual analysis and qualitative research) explained and developed the instrument's fundamental items. This section included in-depth, semistructured interviews with 21 students and eight experts. The second section measured the psychometric properties of the instrument. Twenty students assessed the instrument's qualitative and quantitative face validity in this section. The instrument's content validity ratio (CVR) and content validity index (CVI) were evaluated. In addition, exploratory factor analysis (performed by 251 students) was used to establish construct validity. Internal and test–retest reliability was determined using Cronbach's alpha and intraclass correlation coefficients (ICC), respectively. Results: During face and content validity assessment, a 37-item questionnaire was finalized. Exploratory factor analysis led to the identification of three factors, including “examinations and glasses-related behaviors,” “symptom-related behaviors,” and “screen-related behaviors.” The three extracted factors accounted for 37.9% of the variance. Cronbach's alpha was equal to 0.874 when evaluating internal consistency, and the ICC value for the total score of the questionnaire was 0.885 (0.810–0.941), indicating excellent test–retest reliability. Conclusions: These results demonstrate the questionnaire's validity and reliability. This instrument assesses the prevalence of university students' most significant eye health risk behaviors. Consequently, it helps prevent eye problems.

Background: As a public health emergency, coronavirus disease 2019 (Covid-19) is a threat to our future; therefore, appropriate health system responsiveness (HSR), as an important criterion, is of crucial importance. This study aimed to evaluate the different dimensions of responsiveness of healthcare centers, both public and private, providing COVID-19 services in Tehran. Methods: Following a cross-sectional design, this study was conducted in Tehran (the capital city of I.R. Iran) from May to November 2020. Data were collected using the World Health Organization (WHO) questionnaire on responsiveness. Two hundred questionnaires were filled out through face-to-face or phone call interviews in two public and private hospitals (100 in each) providing Covid-19 services. Participants were selected using the convenience sampling technique among all those who received Covid-19 services during the past six months in the city of Tehran. Results: The mean age of participants was 45.9 ± 15.9 and 51.5% were female. On an average, 52.6% of the respondents evaluated at least one dimension of responsiveness as appropriate and/or strongly appropriate. Communication obtained the highest score (58.2%), followed by confidentiality (56.5%), dignity (56%), and prompt attention (52%). Meanwhile, autonomy and choice were evaluated as poor (moderate, weak, and strongly weak) by 63.5 and 52.5% of respondents. There was no significant association between the type of healthcare center (i.e., public or private) and responsiveness (p-value = 0.896). However, there was a significant difference between gender (p-value = 0.036) and education level (p-value = 0.014) with responsiveness. According to the respondents, prompt attention and choice were the most and least important dimensions, respectively. Conclusions: Evaluation of HSR in the era of COVID-19 not only provides a tool for qualitative assessment of services but also plays an important role in providing feedback to policymakers to adopt effective policies.

Background: This study aimed to design and evaluate the cooling power of local cooling coats for the head, neck, ankles, and wrists. Methods: Local cooling coatings were designed using Iranians workers' existing 50^th anthropometric percentile data. After immersing the cooling coats in water for 5 minutes, they were placed in a chamber at 30°C, 35°C, and 40°C and 30% and 60% humidity and 0.2-0.4 m/s air velocity for 120 minutes. The amount of water evaporation was measured by weighing each coat before and after entering the chamber, and then the cooling power of each coat was calculated based on the amount of water evaporation. Results: The average cooling power of cooling coats with covering areas (two wrists 933.75 cm², two ankles 1467.37 cm² and head and neck 1270 cm²) that the total area of the cover is 3671.12 cm², i.e., about 20% of the body at 30% relative humidity in 30°C, 35°C and 40°C was 67, 77 and 89 watts, respectively. At the mentioned temperature and in 60% relative humidity, the cooling power was 34, 40, and 55 watts. As the relative humidity increased, the cooling power of the coats decreased. Conclusions: Local evaporative cooling coat on the head, neck, wrists, and ankles can reasonably repel excess heat entering the body. The best performance of these coats is in hot and dry environments. Probably, if used in conjunction with cooling vests in environments with high temperatures and heavy activity, it can act as a supplement to cooling vests and have a significant effect on improving functions.

Background: The aim of the study was to assess the prevalence and correlates of cardiovascular health (CVH) status among adults in Afghanistan. Methods: In a national cross-sectional household survey 3,447 adults completed CVH measurements in Afghanistan. Criteria for ideal CVH (ICVH) were physical activity, healthy diet, non-smoking, fasting blood glucose (<100 mg/dL), body mass index (<25 kg/m²), total cholesterol (<200 mg/dL), and blood pressure (<120/<80 mmHg). Results: More than one-third (34.3%) of participants had 5-7 ICVH, 45.7% 3-4 ICVH, and 20% had 0-2 ICVH. In adjusted logistic regression analysis, secondary or more education (AOR: 1.80, 95% CI: 1.22-2.66) was positively associated, and older age (45-69 years) (AOR: 0.33, 95% CI: 0.26-0.42), and urban residence (AOR: 0.67, 95% CI: 0.51-0.88) were inversely associated with 5-7 ICVH. Conclusions: The prevalence of ICVH was low in Afghan adults. Population measures may be used to improve CVH targeting identified associated factors.

Background: Aging is identified as a risk factor for vitamin D deficiency (VDD) therefore this investigation was designed to determine the prevalence of VDD and its determinants in a sample of older adults. Methods: The data of this study were obtained from the baseline wave of the Longitudinal Aging Study (LAS). Demographic, past medical history, medication history, and smoking behavior were collected using an interview approach. The physical activity and nutritional status of the participants were assessed using a standard questionnaire. Anthropometric indices were measured according to a standard protocol then body mass index (BMI) was calculated. Serum vitamin D and calcium levels were measured by autoanalyzers. Univariate and multiple logistic regression models were applied to detect the associated factors with VDD. Results: Mean age of the participants was 71.82 (SD = 7.63) years. A total of 1319 people participated in our study, and 51.16% (n = 688) were female. A total of 8.42% (n = 111) of the participants had VDD and 17.06% of them (n = 225) had insufficient vitamin D levels. In the multivariable logistic regression model, the age group of 70–79 years in comparison with the age group of 60–69 years had a 43% less chance of VDD. Furthermore, being overweight (OR = 0.36, P = 0.01) and obese (OR = 0.35, P = 0.02), and taking vitamin D supplements (OR = 0.31, P = 0.04) were significantly associated with VDD. Conclusions: Our results showed that 25% of older adults had vitamin D deficiency or insufficiency. In addition, some modifiable lifestyle factors were associated with VDD. Given that, old age is considered a risk factor for VDD. Therefore, detection and improvement of VDD may be a preventive measure in at-risk subjects.

Background: Obstructive sleep apnea (OSA) is the most common sleep-realted respiratory disorder. It is frequently comorbid with cardiovascular, cerebrovascular, and metabolic diseases and is commonly observed in populations with these comorbidities. Investigators aimed to assess the effect of OSA on glycemic control in patients with diabetes. Methods: In this cross-sectional study, 266 adult patients with diabetes mellitus (DM) attending the outpatient endocrinology clinic at the Guilan University of Medical Sciences were enrolled. Patients completed a checklist that included demographic characteristics, factors, and laboratory results in addition to Berlin and STOP-BANG questionnaires to evaluate the risk of OSA. Data were analyzed by independent t-test, Mann–Whitney U test, and Chi-squared or Fisher's exact tests using the Statistical Package for the Social Sciences (SPSS) version 17. Results: A total of 266 patients with DM were enrolled in this study (34.6% males, mean age 47.00 ± 19.04 years). Based on the Berlin Questionnaire, 38.6% of all participants were at high risk of developing OSA. Based on the STOP-BANG Questionnaire (SBQ), 45.1% were at moderate and high risks. Additionally, this questionnaire showed a significant difference between low and moderate-to-severe groups regarding sex, age, body mass index (BMI), neck size, other chronic diseases, types of DM, use of insulin, Berlin Questionnaire, fasting blood sugar (FBS), and mean HbA1c. Conclusions: Based on the SBQ, our results indicated a significant relationship between OSA and glycemic control according to mean HbA1c and FBS. Therefore, by controlling the OSA, we may find a way to acheieve better glycemic control in diabetic patients.

Background: The dietary approaches to stop hypertension (DASH) encourages high fruit, vegetable, and lean protein consumption and low salt, red meat, and fat intake to prevent or treat hypertension. However, besides hypertension, adherence to this diet has been shown to decrease other cardiovascular risk factors. Methods: This study assessed the relationship between the DASH diet and cardiovascular risk factors in a cross-sectional study of 2,831 adults chosen by multistage cluster sampling from 27 counties of Khuzestan province, Iran. DASH scores were calculated using data obtained from a qualitative food frequency questionnaire. Regression models were used to evaluate the association of DASH scores and common cardiovascular risk factors. Results: Significant trends were observed across quintiles of DASH scores for systolic blood pressure, fasting blood sugar, triglyceride, total cholesterol, and its components (p < 0·05). After adjusting for potential confounders such as sex, age, ethnicity, residence, wealth score, physical activity, energy intake, and family history of heart disease, the multiple regression analysis for each cardiovascular risk factor revealed that being in the highest quintile of total DASH score (OR = 0.72, 95% CI 0.52–0.99) was negatively associated with hyperglycemia. Conclusions: This study showed a positive relationship between DASH diet adherence and lower serum levels of glucose, triglycerides, and cholesterol. Prospective studies are needed to confirm these findings.

Background: A further understanding of the mechanisms linking inflammation to T2D and related complications can help prevent or control this silent but dangerous disease. This study was conducted to determine the association between paraoxonase 1 (PON1) activity and interleukin-6 (IL-6) in type 2 diabetes (T2D). Furthermore, we have evaluated the role of age and gender in the relationship between the PON1 activity and IL-6. Methods: A total of 105 people with T2D were enrolled in this study. IL-6 levels were determined using ELISA. For the PON1 activity assay, the hydrolysis rate of the substrate phenylacetate was spectrophotometrically assayed in serum at 270 nm. The determined velocities were the initial velocities of substrate hydrolysis. Results: PON1 activity was negatively correlated with IL-6 in total data (r = −0.34, P = 0.001). In both groups with age ≥50 and <50 years, PON1 activity was negatively correlated with IL-6, but the correlation was significant in patients aged 50 years and above (r = −0.358, P = 0.005) compared with patients with age <50 years. In both women and men, PON1 activity was negatively correlated with IL-6, but the correlation was significant in women (r = −0.318, P = 0.006) in comparison with men. Conclusions: Inverse association between PON1 activity and IL-6 in T2D may represent the oxidative–inflammatory interaction in this disease. Our findings highlight that at older ages and in women, the associations between lower PON1 activity and higher IL-6 concentrations are more evident, and this should be considered in patients with T2D.

Background: Childhood type 1 diabetes mellitus (T1DM) is an autoimmune disease which is increasing in incidence, but little is known about the events that trigger the autoimmune process. Most of the time, these processes begin in prenatal and natal periods; therefore, this study aimed to investigate the prenatal and neonatal risk factors of T1DM in childhood. Methods: This case-control study has been performed on children with T1DM who referred to the 17^th Shahrivar children's hospital. The control group consisted of healthy siblings of the case group. Data were gathered using a form that included maternal and neonatal characteristics. Data were reported by descriptive statistics in SPSS 19. To investigate the effect of quantitative and qualitative variables on the development of T1DM, logistic regression and Chi-square tests were used, respectively. Results: Birth weight, birth height, and maternal weight gain during pregnancy had a significant relationship with T1DM (odds ratio [OR] = 1.23, 2.57, and 1.14, respectively). In addition, there was a significant relationship between gestational hypertension (OR = 5.27), neonatal jaundice (OR = 3.42), cesarean section (OR = 2.06), and being non–first-born child (OR = 2.32) and T1DM. Also, premature rupture of membrane, maternal urinary tract infection, and nonexclusive breastfeeding had a significant association with T1DM (OR = 4.37, 3.94, and 2.30, respectively). There were no statistically significant differences between maternal age, sex, neonatal respiratory disease, prematurity, and neonatal infections and T1DM (P > 0.05). Conclusions: Prenatal and neonatal risk factors can have a significant role in the occurrence of TIDM. Therefore, considering these risk factors can have a preventive effect on T1DM.

Background: During the COVID-19 pandemic, stunting is estimated to increase 2.4 times higher (It seems that some information is missing here because the usage of the word 'higher' hints at a comparison with some other statistic. Or please consider making the following changes in the statement: “…stunting is estimated to be 2.4 times higher than the normal trend.” which can increase mortality, morbidity, and cause economic losses in the future. This study aims to identify the risk factors for stunting during the COVID-19 pandemic. Methods: An unmatched case-control study was conducted to compare the exposure of stunted (cases) and non-stunted (controls) children. There were 127 children aged 6-24 months, 43 cases, and 84 controls. Results: The probability of stunting was two times greater in children who experienced good changes in the consumption of tofu/tempeh (p: 0.047; AdjustedOR (aOR): 2.296; 95% CI 1.013-5.205) and fourtimes greater in children who have a mother that did not receive iron supplementation during pregnancy (p: 0.030; aOR: 4.344; 95% CI: 1.154-16.355). Conclusions: Based on the above results, increasing access to nutritious food, and the delivery of services and information related to maternal and child health services during the pandemic needs to be intensified by using innovative low-risk platforms.

Background: The risk of developing tobacco-related cancer and chronic heart and lung disease is greater if addiction starts in adolescence. Even experimental use of tobacco in adolescents significantly increases the risk of addiction in adulthood. This study intends to collect valuable data regarding sociodemographic characteristic of tobacco use, pattern of dependence among adolescent tobacco users, which will be essential for formulating recommendations, and their possible intervention aimed at reducing the problem of tobacco use. Methods: A community-based cross-sectional study was done where 400 subjects were enrolled. Nonprobability Snowball sampling technique was used to locate adolescents aged 12–18 years, who were practicing tobacco use. Face-to-face interviews were taken for data collection. Fragerstorm dependency test for tobacco was used to classify dependency of tobacco product into high and low dependency. Data was analyzed using Chi-square test and proportions using SPSS software version 21. Results: Majority of the subjects were in the age group of 16–18 years; mean age for initiation of tobacco was 15.6 years. Gutkha was the predominant form of tobacco product being used. Peer pressure 192 (48.0%) was the major reason for initiation of tobacco use. A significant association was found between dependency on tobacco and age, literacy, and socioeconomic status. Conclusions: Tobacco use starting from early age has many health implications. There is a need for stringent laws against the selling of tobacco to adolescents and targeted health awareness program against tobacco.

Background: Insomnia affects the daily activities of the sufferers and reduces attention and memory. Cognitive behavioral therapy is an expensive treatment and is not applicable to all patients, and long-term treatment with sleep medication can have side effects such as drug dependency. As an alternative form of non-pharmacological treatments, the effect of exercise therapy on improving the symptoms of insomnia is addressed in the current study. Methods: A total of 32 patients diagnosed with insomnia participated in the study, from which 16 received combined resistance-aerobic exercise therapy. The rest of the patients comprised the control group. The intervention group went through a 12-week intervention in the form of aerobic exercise for 3 days a week and resistance training for another 3 days a week. Patients' sleep quality was assessed by the Pittsburgh test before and after the intervention. Results: The results showed that combined aerobic-resistance exercise can improve sleep quality in patients with insomnia as well as increase subjective sleep quality and actual sleep duration, and decrease daytime dysfunction due to sleeping problems. Conclusions: This study shows that, along with other insomnia treatments, exercise can improve the sleep quality of patients.

Background: Recently, several have evaluated the association between the components of the dietary inflammatory index (DII) score with the risk and severity of Coronavirus Disease 2019 (COVID-19). For the first time, we examined the association between DII^® with risk of coronavirus infection and symptom severity through a case-control study in Iran. Methods: The present case-control study was conducted on COVID-19 cases (n = 100) and healthy control (n = 100) volunteer, aged from 18 to 65 years. Dietary intake, DII, body mass index, COVID-19 infection, and the severity of its symptoms were assessed for each participant. A multivariable logistic regression analysis test was used to estimate the odds ratio and 95% confidence interval. Results: Our results demonstrated that COVID-19–infected patients were significantly older and had longer history of diabetes as compared to the healthy control group (P <.05). Furthermore, the participants with COVID-19 had a significantly greater intake of total fat (P =0.259), saturated fat (P =0.005), and dietary fiber (P = .004). In contrast, individuals in the healthy control group had a higher intake of carbohydrate (P = .005), sodium (P <.001), and iron (P <.001). However, there was no significant difference in DII score between COVID-19 and healthy controls (P =.259). In addition, we did not detect any specific association between DII score and risk of COVID-19 infection (odds ratio = 1.08, 95% confidence interval: 0.92 to 1.27; P =.294) and the severity of its symptoms (P >.05). Conclusions: There appears to be no specific association between DII score and risk of COVID-19 infection and the severity of its symptoms. More prospective cohort studies are necessary to confirm the veracity of our results.

Background: Globally and in Thailand, the incidence of colorectal cancer (CRC) is third-ranked behind lung and breast cancer, respectively. This hospital-based retrospective cohort study aimed to determine factors associated with mortality among patients with CRC. Methods: This study was performed by using the secondary data of the cancer registry among patients with CRC registered in Phatthalung Hospital. Two hundred twenty-eight patients with CRC were diagnosed and followed up from January 2014 to December 2018. Multiple logistic regression analysis was used to analyze factors associated with mortality among subjects with CRC. Results: The results revealed that the proportion of mortality among subjects with CRC was 50.44% (115 cases) at six months of following up. Subjects who had an increasing age every ten years (adjusted odds ratio [OR_adj] = 1.40, 95 percent confidence interval [95% CI]: 1.09–1.80) were diagnosed with CRC at stage 3 (2.64, 1.19–5.84) and at stage 4 (11.63, 2.69–50.15) more likely to die. Also, subjects who received a combination of chemotherapy and radiotherapy treatment (3.44, 1.20–9.85), combination treatment of surgery, and postoperative care (2.46, 1.22–4.94) were more likely to die. Subjects who had not had surgery treatment were more likely to die (35.00, 7.44–168.27). Conclusions: In conclusion, factors such as the age of patients, stage of CRC, and treatment were associated with mortality among patients with CRC. Hence, medical and health professionals should consider these factors according to the treatment and optimization in patients with CRC.

Background: Education of the patients with Coronavirus Disease 2019 (COVID-19) and their families is necessary to improve the quality of life. This study investigated the effect of person and family-centered training via telenursing on the quality of life in patients with COVID-19. Methods: This interventional study was performed on 88 patients with COVID-19 18--65 years and 44 family members referred to the Bank Melli Hospital, Tehran, Iran. The samples were randomly assigned into two groups person-centered and family centered. A cyberspace group including patients and their families was created. Four educational sessions planned (15--30-min-every day) and three sessions planned for completing the questionnaires via phone. The data were collected using demographic characteristics form and the 12-item Short-Form Health Survey version 2 before and 6 weeks after the intervention and were analyzed in SPSS 22 using Chi-square test, paired t-test, and independent t-test. Results: The mean scores of quality-of-life increased significantly in the person-centered group from 26.81 ± 5.15 to 34.4 ± 4.39 before and six weeks after intervention, respectively (p < 0.001). The means scores of quality-of-life increased significantly in the family-centered group from 28.11 ± 4.79 to 35.86 ± 3.85 before and 6 weeks after the intervention, respectively. (p < 0.001). Conclusions: The person and family centered methods increase the mean scores of quality-of-life of patients with COVID-19. The family centered method can be more effective to improve the quality of life of these patients.

Background: Hearing loss is one of the most common congenital disorders. The Early Diagnosis and Intervention Process is designed for the early diagnosis and intervention of hearing loss in infants. The present study aimed to examine the results of Early Hearing Detection and Intervention (EHDI) in northeastern Iran from 2005 to 2019. Setting: Northeastern Iran. Methods: In most cases, the two-stage protocol (otoacoustic emissions [OAE] and automated auditory brainstem response [AABR]) has been used. Infant assessment methods included the use of OAE, ABR, auditory steady-state response, high-frequency tympanometry, and behavioral audiometry. Interventions included medical interventions, hearing rehabilitation, hearing aids, and cochlear implants. Results: 1,162,821 infants were screened. The screening coverage increased from less than 1% in 2005 to about 99% in 2018. The referral rate has been about 1%. 2.17 out of every 1000 infants are hearing impaired, and the most common cases are bilateral hearing loss and mild to moderate hearing loss. Conclusions: During 2005 to 2019 the coverage rate reached to more than 95% of live births. To improve the EHDI process in this population, better follow-up of diagnosed neonates and expansion of diagnostic and intervention services are needed.

Background: The evolving COVID-19 outbreak requires a high level of population awareness and other measures to protect public health. Objectives: In this study, we aimed to identify knowledge, awareness, and fears of the Saudi population regarding COVID-19 during this pandemic. Methods: A cross-sectional survey study was conducted from April to May 2020 in different Saudi areas. Data were collected via online survey software (Google Forms), and the data collection tool was developed and validated by the study authors to fulfill the study objectives. Data were analyzed using SPSS version 21.0. Descriptive statistics and Chi-square tests were used for comparison between groups. The statistical significance was considered when the P value ≤0.05. Results: Study participants included 2982 people with 66.8% females. The average percentage of the awareness levels of the current study population was 68%. The vast majority (95.1%) did not know how the virus spread while 94.7% of the participants know the distance that a person should maintain from another person. Significantly higher percentages (70%) knew about and were aware of the prevention methods, including social distancing and hand hygiene, and 73.5% knew that elderly people with chronic diseases are the highest risk group to become infected. The highest significant fear of COVID-19 was from lack of treatment, which was reported by 77.5% of the participants with a P value of <0.05. Conclusions: Our study shows that the population has acceptable knowledge about COVID-19. Education and work-based awareness programs about COVID-19 are needed, especially for prevention and treatment aspects.

Background: Smoking is a public health problem that affects the adolescent population's health. This study aimed to investigate the relationship between extroversion (compared with introversion) and transition in cigarette and hookah smoking stages in high-school students to use the results in smoking prevention programs. Methods: A sample of 2312 students aged 15–16 years in Tabriz were included in the study. Demographic characteristics, cigarette, hookah smoking status, and Eysenck's extroversion questionnaires were completed by all students in the selected schools. Eight months later, cigarette and hookah smoking status were assessed again to determine transition in smoking stages. The marginal homogeneity (MH) test was used to compare the smoking status at the beginning and 8 months later. The generalized estimating equation (GEE) method with the ordinal link was applied to estimate the effect of extroversion on transition in smoking stages. Results: The mean (standard deviation) age of the students participating in the study was 15.5 (0.5) years. MH test results showed that, in general, transmission in the stages of both cigarette and hookah smoking in 8 months was significant in students (P-value < 0.0001). Extrovert personality had a significant positive effect on the transition from lower stages to higher cigarette and hookah smoking stages according to the GEE with ordinal link (P = 0.01). In cigarette and hookah smoking, extrovert persons transited to higher stages 1.64 and 1.55 times more than introvert persons. Conclusions: Being an extrovert person had a significant effect on the transitioning to higher stages of smoking cigarettes and hookah. In designing cognitive programs to prevent people from smoking or encourage them to quit smoking, considering this dimension of personality trait can be useful in the efficacy of the program.

Background: Disturbed biochemical factors have been observed in viral infections including SARS, Ebola virus, and now COVID-19. This study aimed to evaluate the association between Calcium axis' derangements and hospital duration, ICU admission, mechanical ventilation, and death in patients with COVID-19. Methods: 428 hospitalized patients with COVID-19 were included in this study. On the first day of admission, the patients were extensively evaluated for biochemical and hormonal factors and followed up until discharge/death. The association between hyperphosphatemia, hypoalbuminemia, and hypocalcemia and major outcomes, including hospital duration, ICU admission, mechanical ventilation, and death, was investigated by logistic regression analysis. Results: Hyperphosphatemia and hypoalbuminemia were present in 27 (6.3%) and 59 (13.8%) cases, respectively in the study population. The results of the present study reveal the relation of these factors with worse outcomes in COVID-19 patients; such as hospital duration, ICU admission, mechanical ventilation, and death. On the other hand, high frequency of hypocalcemia (59.1%, 253 subject) has no significant influence on the mentioned outcomes (All P values were greater than 0.05). Conclusions: Poor outcomes were associated with hyperphosphatemia and hypoalbuminemia. It seems that we should evaluate the patients for derangements of phosphate, albumin, and calcium and try to treat them for all COVID-19 patients.

Background: The present study aimed to investigate the effect of garlic supplementation on oxidative stress markers in patients with polycystic ovary syndrome (PCOS). Methods: Eighty patients with PCOS were randomized and instructed to consume either garlic supplementation (800 mg/day) or a placebo (starch) for 8 weeks. They were also asked to avoid intake of any other supplement during the study. Oxidative stress-related markers including total antioxidant capacity, catalase, glutathione, malondialdehyde concentrations, and anthropometric measures were assessed at baseline and end of the trial. Results: Garlic supplementation resulted in significant improvement in catalase concentration (1.82 ± 9.28 vs. –1.55 ± 8.66; P value: 0.03), glutathione levels (29.15 ± 57.53 vs. 2.42 ± 77.51; P value: 0.048) as well as weight (–0.64 ± 1.94 vs. 0.11 ± 0.82; P value: 0.04), body mass index (BMI; –0.25 ± 0.75 vs. 0.05 ± 0.61; P value: 0.04), and waist circumference (–0.21 ± 0.77 vs. 0.02 ± 0.65; P value: 0.01). However, we failed to detect any significant change in hip circumference, waist to hip circumference ratio, total antioxidant capacity, and malondialdehyde levels between the two groups. Conclusions: The present study indicates that garlic supplementation could be beneficial in improving oxidative stress and weight loss among PCOS women.
