ABSTRACT
BACKGROUND: In this umbrella review, we systematically evaluated the evidence from meta-analyses and systematic reviews of maternal factors associated with low birth weight. METHODS: PubMed, Scopus, and Web of Science were searched to identify all relevant published studies up to August 2023. We included all meta-analysis studies (based on cohort, case-control, cross-sectional studies) that examined the association between maternal factors (15 risk factors) and risk of LBW, regardless of publication date. A random-effects meta-analysis was conducted to estimate the summary effect size along with the 95% confidence interval (CI), 95% prediction interval, and heterogeneity (I2) in all meta-analyses. Hedges' g was used as the effect size metric. The effects of small studies and excess significance biases were assessed using funnel plots and the Egger's test, respectively. The methodological quality of the included studies was assessed using the AMSTAR 2 tool. RESULTS: We included 13 systematic Review with 15 meta-analysis studies in our study based on the inclusion criteria. The following 13 maternal factors were identified as risk factors for low birth weight: crack/cocaine (odds ratio [OR] 2.82, 95% confidence interval [CI] 2.26-3.52), infertility (OR 1.34, 95% CI 1.2-1.48), smoking (OR 2.00, 95% CI 1.76-2.28), periodontal disease (OR 2.41, 95% CI 1.67-3.47), depression (OR 1.84, 95% CI 1.34-2.53), anemia (OR 1.32, 95% CI 1.13-1.55), caffeine/coffee (OR 1.34, 95% CI 1.14-1.57), heavy physical workload (OR 1.87, 95% CI 1.00-3.47), lifting ≥ 11 kg (OR 1.59, 95% CI 1.02-2.48), underweight (OR 1.79, 95% CI 1.20-2.67), alcohol (OR 1.23, 95% CI 1.04-1.46), hypertension (OR 3.90, 95% CI 2.73-5.58), and hypothyroidism (OR 1.40, 95% CI 1.01-1.94). A significant negative association was also reported between antenatal care and low birth weight. CONCLUSIONS: This umbrella review identified drug use (such as crack/cocaine), infertility, smoking, periodontal disease, depression, caffeine and anemia as risk factors for low birth weight in pregnant women. These findings suggest that pregnant women can reduce the risk of low birth weight by maintaining good oral health, eating a healthy diet, managing stress and mental health, and avoiding smoking and drug use.

Potato is one of the essential food products whose health quality is greatly influenced by soil contamination and properties. In the current study, we have investigated the physicochemical characteristics of agricultural areas and the accumulation of nitrite/nitrate and metals in potato products in Hamedan, Iran. After determining the physicochemical characteristics of soil samples from four agricultural regions of Hamedan, 48 potato samples were collected from these regions. The heavy metals and nitrate/nitrite content were determined by ICP-OES and calorimetric methods, respectively. A negative correlation was observed between soil pH changes with nitrite/nitrate content and the accumulation of some heavy elements in potatoes. Furthermore, a positive correlation was found between soil phosphorus content and lead accumulation in potato. In present study, the amounts of lead, nitrate, and nitrite in 83.3%, 56%, and 12% of the collected samples were higher than the permissible limit reported by the World Health Organization (WHO), respectively. The EDI range for nitrate and nitrite was determined to be 130-260 and 1.4-2.7 µg/kg/day, respectively, which is much lower than the RfD set by the US Environmental Protection Agency (USEPA) for nitrite and nitrate. Among metal pollutants, the toxic risk caused by lead in potato consumers was higher than the threshold limit. In conclusion, our findings showed that the physicochemical characteristics of the soil could effectively increase the availability of metal pollutants and nitrite/nitrate to the potato product and significantly reduce its health quality. Therefore, monitoring these pollutants in the soil-potato system, preventing the entry of industrial wastewater, and managing the use of agricultural fertilizers can effectively improve the health of this product for consumers.

The negative impact of hopelessness on mental health makes multiple sclerosis (MS) disease unmanageable. This study aimed to determine the effect of spiritual care on hope in MS patients. In the present randomized controlled trial study, 70 MS patients were selected from the MS Association of Hamadan, Iran, and randomly allocated to intervention and control groups (35 patients per group). A demographic characteristic form and Snyder's Adult Hope Scale were completed before and after the intervention. Spiritual care was provided in weekly group sessions held for four weeks (45-60 min each). The data were analyzed using SPSS-16. Before the intervention, there were no significant between-group difference (P = 0.323). After the intervention, a significant between-group difference was observed (p < 0.001). There was also a significant increase in the mean of hope scores in the intervention group from baseline to follow-up (within-group difference) (p < 0.001), while there was no significant difference between baseline and follow-up in the control group (p = 0.38), confirming the effectiveness of spiritual care in improving hope. Given the impact of spiritual care on increasing patients' hope and improving their psychological state, nurses are advised to devote adequate time to their patients' spiritual needs.
ABSTRACT
OBJECTIVE: One of the systemic infections is Brucellosis which is caused by facultative intracellular bacteria of the genus Brucella. Vitamin D is a fat-soluble prohormone, that metabolizes enzymes and its intracellular receptor creates the active hormone and also mediate in responses of immune system. METHODS: Current research consists of 102 patients with brucellosis who were selected based on culture, PCR results serology, and clinical symptoms. The control group composed of 102 healthy people. The polymorphism of genes (Bsm I, Fok I, Taq I, Apa I) encoding Vitamin D receptor (VDR) were assessed by the PCR-RFLP method. RESULTS: The results showed that ff, tt, aa, and bb genotypes in Fok I, ApaI, TaqI, and BsmI were significant in case/control groups (P-value ≤ 0.0001). The genotype frequency AA in the control group is higher than that of the study group, while genotype frequency aa in the study group is more than the control. The odds ratio for brucellosis in individuals with ff genotype is 37 times higher than that of Ff genotype. Also, the odds ratio of brucellosis in individuals with genotype tt, aa, and bb was 12, 53, and 6 times higher than those of the Aa, Bb, and Tt genotypes. CONCLUSION: The genotypes aa and ff in the positions of the ApaI and FokI are of higher importance. The brucellosis risk in individuals accompanied aa genotype at Apa I is 53 times higher than that of the genotype AA, in other words, AA and BB, TT and FF genotypes are protective against the disease.

BACKGROUND: This study aims to synthesize and characterize hydroxyapatite nanoparticles (nano-HA) and evaluate their effects on the remineralization of demineralized enamel in the presence to Er,CR: YSGG laser irradiation. MATERIALS AND METHODS: Enamel specimens from 44 human molars were divided into four groups: control, demineralized enamel, demineralized enamel treated with nano-HA, and demineralized enamel treated with nano-HA followed by Er,Cr:YSGG laser irradiation (0.5, 20 Hz, 60 µs, 20 s). Vickers microhardness test was used to evaluate the enamel surface hardness. The morphology and chemistry of enamel surfaces were assessed using scanning electron microscopy (SEM) and Raman spectroscopy, respectively. RESULT: The result of this study showed that the application of Er,CR: YSGG laser irradiation to demineralized enamel treated with nano-HA had the highest impact on its microhardness. CONCLUSION: ER,CR: YSGG laser irradiation promotes enamel remineralization after treatment with nano HA.

BACKGROUND: We hypothesized that the addition of coenzyme Q10 (CoQ10) to pregabalin might be helpful in improving symptoms in patients suffering from painful diabetic neuropathy (PDN). METHODS: One hundred twelve patients with PDN were randomly allocated to receive CoQ10 + pregabalin (57 patients) or placebo + pregabalin (55 patients). Besides pregabalin (150 mg/day), the patients, upon their group assignment, received CoQ10 at a dosage of 100 mg every 8 h or matched placebo for 8 consecutive weeks. The primary efficacy measure was the changes in the pain intensity from baseline to endpoint measured on an 11-point NRS (numeric rating scale). Secondary efficacy measures included the changes in the pain-associated sleep interference score (SIS) as well as the patients' global improvement with treatment measured on the Clinicians' and Patients' Global Impression of Change (CGIC/PGIC). RESULTS: On the intenttotreat population (ITT) analysis, the CoQ10 + pregabalin regimen resulted in significantly greater pain relief than the placebo + pregabalin regimen. By the end of week 2, the decrease in the mean pain NRS score was similar in both groups, but at the end of weeks four and eight, the decrease in the mean pain NRS score was significantly greater in patients taking CoQ10 + pregabalin than in those taking placebo + pregabalin (p value = 0.01 and < 0.001, respectively). Likewise, at the end of week 8, the decrease in the pain-associated SIS was significantly greater in the patients supplemented with CoQ10 compared to placebo. Furthermore, the proportion of the responder patients (those having ≥ 50% decline in the mean pain NRS score) as well as the proportion of patients rated ''very much'' or ''much improved'' on the CGIC/PGIC scales were also significantly higher in the CoQ10 + pregabalin-treated patients than placebo + pregabalin-treated patients. CONCLUSIONS: Our data support the idea that diabetic patients suffering from PDN may benefit from using antioxidant and anti-inflammatory supplements like CoQ10. However, further studies are required before supplementation with CoQ10 can be recommended for treating PDN. TRIAL REGISTRATION: The trial was registered at Iranian Registry of Clinical Trials (identifier code: IRCT20120215009014N385). Registration date: 2021-02-21.

BACKGROUND: This study aimed to decompose the age and cause inequality in life expectancy between two Iranian provinces with the highest and the lowest life expectancy using the Arriaga method. METHODS: The required data was extracted from the death registration system (DRS) and statistical center of Iran. First, we calculated life expectancy at birth for 31 provinces of Iran using life tables, and subsequently, two provinces with the highest and the lowest life expectancy were determined. To decompose the age and cause share in the life expectancy gap between the two provinces, we used Arriaga's method. RESULTS: Tehran with 80.09 years and Sistan and Baluchistan with 72.9 years had the highest and the lowest life expectancy among Iranian Provinces respectively. As a result, the life expectancy gap between Tehran and Sistan and Baluchistan was 7.19 years. Results of age decomposition showed that the highest share in the life expectancy gap attributed to the age group under one year (1.25 years). In terms of the cause of death, the highest percentage belonged to hypertensive diseases with a share of 1.77 years. CONCLUSIONS: There is a wide gap between two provinces with the highest and the lowest life expectancy. Age less than one year and hypertensive diseases were major factors in this inequality. Therefore, policy-makers should concentrate on improvement of survival in children and the reduction of hypertensive diseases to promote life expectancy in Sistan and Baluchistan.

BACKGROUND: Preliminary evidence is promising regarding the anxiolytic effects of statins in animal models of anxiety. Hence, this study aimed to evaluate the efficacy of simvastatin augmentation versus placebo in the treatment of patients with generalized anxiety disorder (GAD) with residual symptoms despite treatment with selective serotonin reuptake inhibitors (SSRIs). METHODS: A double-blind, 8-week controlled trial was conducted from August 2018 to December 2019 in an outpatient psychiatry clinic in Hamadan, Iran. A total of 138 patients with a diagnosis of GAD were assessed for eligibility. Of them, 84 patients who met the study criteria were randomly assigned either to the adjuvant simvastatin (20 mg/day) or to the placebo group. Standard medication consisting of SSRIs was consistent 2 months prior to and during the study. The severity of anxiety symptoms for each patient was assessed based on the Hamilton Anxiety Rating Scale (HAM-A) score at baseline, week 4, and week 8 after treatment. Additionally, blood lipid values were assessed at baseline and on completion of the study. RESULTS: Thirty-three out of 42 patients in the intervention group and 35 out of 42 patients in the control group completed the 8 weeks of the study period. Compared to the placebo group, in the simvastatin group cholesterol, triglycerides, and low-density lipoprotein significantly decreased, and high-density lipoprotein significantly increased over time. General linear model analysis demonstrated that although over time a higher decrease in mean HAM-A scores was observed in the intervention group compared to the control group, this difference was not statistically significant (p = 0.11). In addition, at the end of the study, the number of responders and remitters was comparable in the two groups. CONCLUSIONS: The results from this clinical study did not support the potential efficacy of adjunctive simvastatin in the treatment of patients with GAD. Thus, large-scale and long-term clinical trials are required to more accurately assess the potential efficacy of statins in the treatment of patients with anxiety disorders.

BACKGROUND: Late-diagnosis of HIV is a major challenge for the control and prevention of AIDS in the world. The present study aimed to specify factors associated with the late diagnosis of HIV in Iran from 1987 to 2016. METHODS: In this retrospective cohort study, data for 4402 diagnosed HIV/AIDS patients were extracted from 158 behavioral disease counseling centers of 31 Iranian provinces. We defined late diagnosis as having a CD4 count less than 350 within 3 months after diagnosis. Multiple logistic regression analysis was used to determine the factors influencing late diagnosis. Moreover, we used multivariate Cox regression to assess the association of these factors with the patients' survival. RESULTS: In this study, the prevalence of late diagnosis among the patients was 58.2%. People aged 50 years and over (adjusted OR = 3.55), transmission through blood transfusion (adjusted OR = 2.89), co-infection with tuberculosis (adjusted OR = 2.06), and male gender (adjusted OR = 1.38) were the strongest predictors for late diagnosis of HIV. On the other hand, baseline CD4 (adjusted HR = 2.21), people aged 50 and over (adjusted HR = 1.81), male gender (adjusted HR = 1.76), being a widow (adjusted HR = 1.68), people with unknown transmission way (adjusted HR = 18.24), people who inject drugs (adjusted HR = 1.87), diagnosis at previous years (adjusted HR = 2.45) and co-infection with tuberculosis (adjusted OR = 1.77) significantly associated with the survival of patients. CONCLUSION: The prevalence of late diagnosis is high among Iranian HIV/AIDS. The risk factors of late diagnoses include being males and aged 50 years and over, transmission through blood transfusion, and co-infection with tuberculosis. Therefore, implementation of screening programs for early diagnosis of HIV these high risk groups is recommended to Iranian health providers and policymakers.

PURPOSE: The trial aimed to investigate the effectiveness of exogenous melatonin as an adjuvant to pregabalin for relief of pain in patients suffering from painful diabetic neuropathy (PDN). PATIENTS AND METHODS: This randomized, double-blind, placebo-controlled trial was carried out between October 2019 and December 2020 in an outpatient specialty clinic in Iran. One-hundred-three type 2 diabetic patients suffering from PDN were randomized into either the melatonin group (n = 52) or the placebo group (n = 51). Besides pregabalin at a dose of 150 mg per day, patients started with melatonin or an identical placebo, at a dose of 3 mg/day at bedtime for 1 week, which was augmented to 6 mg/day for further 7 weeks. The primary outcomes were changes in mean NRS (numerical rating scale) pain score from baseline to endpoint and responder rate (patients with a reduction of 50% and higher in average pain score compared with baseline). Secondary endpoints were changes in mean NRS pain-related sleep-interference score, overall improvement evaluated by Patient and Clinical Global Impressions of Change (PGIC, CGIC), and impact of the intervention on patient's Health-related quality of life (QOL). All analyses were conducted on an Intention-to-Treat (ITT) analysis data set. RESULTS: At the study endpoint, treatment with melatonin resulted in a considerably higher reduction in the mean NRS pain score in comparison with placebo (4.2 ± 1.83 vs. 2.9 ± 1.56; P-value < 0.001). In terms of treatment responders, a greater proportion of melatonin-treated patients satisfied the responder criterion than placebo-treated patients (63.5% vs. 43.1%). Melatonin also reduced pain-related sleep interference scores more than did placebo (3.38 ± 1.49 vs. 2.25 ± 1.26; P-value < 0.001). Further, at the endpoint, more improvement was also seen in terms of PGIC, CGIC, and Health-related QOL in patients treated with melatonin than placebo. Melatonin was also well tolerated. CONCLUSION: The present results showed that melatonin as an adjunct therapy to pregabalin might be helpful for use in patients with PDN. However, confirmation of these results requires further studies.

Multiple sclerosis (MS) is a chronic disease that affects the central nervous system and is characterized by inflammation, demyelination, and degenerative changes. Relapsing-remitting MS (RRMS) is the most common form of MS. Fingolimod (FTY720) is a once-daily disease-modifying agent approved to treat RRMS, and it binds to sphingosine 1-phosphate receptors. Milk thistle (silybum marianum; SM) is an herb generally used to protect the liver with antioxidant and antifibrotic effects. The purpose of this study was to evaluate the effects of silymarin on reducing liver complications of FTY720 in patients with RRMS and decrease the oxidative stress that plays an important role in the pathogenesis of this disease. Forty-eight patients with RRMS were divided into two groups using random assignment: the placebo and drug-treated groups. Participants of intervention and control groups took FTY720 with silymarin and placebo without silymarin per day for six months. Findings showed a significant reduction in the level of ALT and AST, reduction of main pathogenic factors in MS containing malondialdehyde, and also a significant rise in total antioxidant capacity, and total thiol groups in the serum of patients treated with silymarin as compared with the placebo group. Our outcomes propose the practical effects of silymarin in multiple sclerosis and reduction of hepatic side effects of fingolimod.

BACKGROUND: Our knowledge on the prevalence of high-risk behaviors among women of Alborz is not reliable due to the sensitivity of the issue. This study aimed to estimate the prevalence of seven risk behaviors among the reproductive age women in Alborz Province, Iran. METHOD: In this cross-sectional study, 2000 women were randomly selected from a registered healthcare system in 2019. A researcher-made questionnaire was used to collect the required data. The prevalence of the risk behaviors including drug abuse, hookah, alcohol drinking, tobacco smoking, extramarital intercourse, and gambling was estimated using the unmatched count technique, and the prevalence rate was reported at a 95% confidence interval. RESULTS: The response rate for this study was 95%. The estimated prevalence for drug abuse, hookah, alcohol drinking, tobacco smoking, extramarital intercourse, and gambling were 3% (95%CI: 2.78 to 3.22), 10.5% (95%CI: 10.29 to 10.71), 7% (95%CI: 6.78 to 7.22), 10% (95%CI: 9.78 to 10.22), 8.7% (95%CI, 8.29 to 8.71), and 7.5% (95%CI, 4.71 to 7.28), respectively. CONCLUSION: High risk behaviors are highly prevalent among Iranian women. Enforcing laws, prohibition, marketing restrictions, increasing taxation, expanding treatment, promoting condom distribution and providing community-based service are recommended to reduce the effects of high risk behaviors among women.

BACKGROUND: Findings on the association between Toxoplasma gondii (T. gondii) infection and suicide are contradictory. This paper aimed to resolve this uncertainty by conducting a meta-analysis. METHODS: We found the relevant studies using keywords include "Toxoplasmosis" and "Suicide" and the related synonyms in international databases such as ISI, Medline, and Scopus. The eligible studies were included in the meta-analysis phase. The random effect approach was applied to combine the results. RESULTS: Out Of 150 initial studies, 15 were included in the meta-analysis. Odds of suicide in people with T. gondii infection was 43% (OR: 1.43, 95%CI; 1.15 to 1.78) higher than those without this infection. The test for publication bias was not statistically significant, which indicates the absence of likely publication bias. CONCLUSION: This study confirms that T. gondii infection is a potential risk factor for suicide. To reduce cases of suicide attributable to T. gondii infection, it is recommended to implement some measures to prevent and control the transmission of the disease.

BACKGROUND: Brain stroke causes physical and mental disabilities, as well as dependence on one's family. In such cases, the families suffer from severe crisis and anxiety due to the unexpected incidence of the disease and unawareness of the associated consequences. OBJECTIVES: The aim of the present study was to evaluate the effectiveness of informational support on the level of anxiety in family caregivers of hemiplegic stroke patients. METHODS: This quasi-experimental study was performed on 78 family caregivers of hemiplegic stroke patients admitted to the Neurology Department of Farshchian Hospital in Hamadan, Iran, over 8 months. The subjects were selected through convenience sampling method and divided into two groups of intervention (nâ¯=â¯40) and control (nâ¯=â¯38). Intervention started from the third day of hospitalization and continued until the eleventh day. During this period, information about the ward, equipment, patient status, and care procedure at home, was provided for the intervention group individually and in groups. On the other hand, the control group only received the routine care. Anxiety level of caregivers was measured through the Spielberger scale both before and after the intervention. Data analysis was performed in SPSS software (version 16). RESULTS: Based on the results, both groups were similar in terms of demographic variables (P > 0.05). Moreover, there was no significant difference between the two groups regarding the mean level of state and trait anxiety before the intervention (P > 0.05). However, after intervention, the mean level of state and trait anxiety of the intervention group showed a significant reduction in comparison to that of the control group (P < 0.05). CONCLUSIONS: According to the findings, it can be concluded that informational support is effective in reducing the state and trait anxiety in family caregivers of stroke patients. Therefore, it is suggested that nurses consider informational support as an important nursing intervention during hospitalization.

BACKGROUND: Multiple risk-taking behaviors are associated with increased risk of poor educational attainment, morbidity and premature mortality. This study involved a large representative sample of Iranian university students addressing multiple risk behaviors and associated factors. METHODS: This cross-sectional study included 4261 participants, involving 13 medical universities throughout the country in 2017. The following six risky behaviors were addressed: (a) smoking cigarettes during the past month, (b) using some kinds of illicit drugs during the past month, (c) drinking alcohol during the past month, (d) engaging unprotected sex during the past year, (e) having suicidal ideation during the past month or attempting suicide in the past year, (f) and Internet addiction. The 20-item internet addiction test and the 28-item general health questionnaire were used. RESULTS: Almost 37.3% of the participants engaged in at least one out of six risky behaviors. The prevalence of Internet addiction was 24.5%, cigarette smoking 13.5%, alcohol use 7.8%, illicit drug abuse 4.9%, unprotected sex 7.8%, suicidal ideation 7.4%, attempting suicide 1.7% and general health problems 38.9%. CONCLUSION: A majority of the Iranian university students studied engaged in at least one risky behavior. Engaging in one risky behavior increases the risk of engaging in other risk-taking behaviors.

BACKGROUND: To achieve the goal of measles eradication, all WHO member countries should continuously monitor the status of measles elimination. This work aims to characterize measles outbreaks in Iran from 2014 to 2016 and calculate the effective reproduction number, given that the country has recently eliminated measles. METHODS: Effective Reproduction Number (R) was estimated to achieve the goal of measles elimination using measles related outbreaks data and epidemiological data from the cases linked to imported cases. Three methods were used to estimate R includes (i) proportion of cases imported, (ii) distribution of outbreak size and (iii) distribution of outbreak generations. RESULTS: Of the 153 outbreaks occurring during the three years of the study, 29 outbreaks (19%) were unknown source, 86% of them were single cases. Estimates of R during the study period by proportion of cases imported were 0.79 (95% CI: 0.73-0.86). Corresponding values for distribution of outbreak size and distribution of outbreak generations methods were R = 0.83 (95% CI: 0.68-0.97) and R = 0.76 (95% CI: 0.54-0.90), respectively. CONCLUSIONS: Estimated values of R represent the important achievement that the outbreaks of measles originating from the indigenous genotype in Iran have been eliminated. Moreover, Iran has also achieved the goal of measles elimination by end of 2015.

BACKGROUND: No reliable and comprehensive study has been published on the incidence and epidemiological profile of meningitis in Iran from 2008 to 2014, before pneumococcal conjugate vaccine (PCV) and pentavalent vaccine (DTPw-Hep B-Hib (PRP-T) vaccine (pentavac) (adsorbed)) introduction. The present study aimed to portray the epidemiological profile of meningitis in Iran from 2008 to 2014. METHODS: Data on meningitis cases aged from 1 day to 110 years were extracted from national notifiable diseases surveillance system from March 2008 to December 2014 in Iran. A total number of 48,006 cases of suspected meningitis were identified and 1468 cases of which met the criteria for diagnosis-confirmed meningitis. Of 1468 cases, 1352 patients were included in the study. RESULTS: The great number of cases reported from urban areas. Moreover, males were more predominant than females (58.51% vs. 33.81%) in total. The estimated annual incidence rate of meningitis varied from 0.28/100000 in 2008 to 0.09/100000 in 2014. Streptococcus pneumoniae, Haemophilus influenzae and Neisseria meningitidis were the most leading pathogens causing bacterial meningitis, accounted for 266(23.44%), 145(12.78%), 95(8.37%) of cases, respectively. Each of the three bacterial species showed a descending trend. The majority of infected subjects are children under five years. CONCLUSIONS: Unlike the decreasing trend of meningitis and high percentage of cultures with negative results, according to World Health Organization recommendation PCV introduction into routine immunization is evident. Implementing an enhanced surveillance system to provide high quality data on epidemiological profile of meningitis in Iran is necessary.

BACKGROUND: Bipolar disorder (BPD) is a chronic and recurrent mood disorder characterized by episodes of mania, hypomania, and major depression. Based on available evidence, mitochondrial dysfunction, oxidative stress, and inflammation have important roles in the pathophysiology of bipolar depression. More specifically, it seems that coenzyme Q10 (CoQ10), a mitochondrial modulator, as well as an antioxidant and anti-inflammatory agent, might be effective in modulating these pathophysiological pathways. Accordingly, the aim of this study was to investigate whether and to what extent, compared with placebo, adjuvant CoQ10 might improve symptoms of depression in patients with BPD. METHODS: A total of 69 patients with BPD with a current depressive episode were randomly assigned either to the adjuvant CoQ10 (200 mg/d) or to the placebo group. Standard medication consisting of mood stabilizers and antidepressants was consistent 2 months prior and during the study. Depression severity for each patient was assessed based on the Montgomery-Asberg Depression Rating Scale scores at baseline, fourth week, and eighth week of the study. RESULTS: Symptoms of depression decreased over time in both groups. Compared with the placebo group, adjuvant CoQ10 to a standard medication improved symptoms of depression after 8 weeks of treatment. In addition, at the end of the study, it turned out that more responders were observed in the CoQ10 group, compared with the placebo group. CoQ10 had minimal adverse effects and was well tolerated. CONCLUSIONS: The present pattern of results suggests that among patients with BPD, compared with placebo, adjuvant CoQ10 probably because of its antioxidant and anti-inflammatory properties can improve symptoms of depression over a period of 8 weeks.

BACKGROUND: The prevalence of vitamin D deficiency in the Iranian community is very high. Women and older people are at the higher risk of vitamin D deficiency. AIM: This study aimed to estimate the prevalence of vitamin D deficiency in Iran by combining the results of various studies. METHODS: This was a systematic review and meta-analysis. Separate strategies were developed for search in national databases (Irandoc, Magiran, SID) and international databases (Web of Science, PubMed, and Scopus) using the keywords of "vitamin D deficiency," "Iran," and "prevalence." The titles and abstracts of the articles were screened and related full texts were appraised. Those articles that met inclusion criteria were selected for meta-analysis. The heterogeneity of the articles was assessed via the Chi-square test. They were combined using the random-effect approach. In addition, the groups were categorized and analyzed in terms of age and gender. RESULTS: Of 639 articles, 30 articles with a sample size of 26,042 people were included for data analysis. The overall prevalence of vitamin D deficiency was reported as 0.56. Subgroup analysis showed that 0.64 of women and 0.44 of men were suffering from vitamin D deficiency. The prevalence of vitamin D deficiency in the age groups under 20, 20-50, and over 50 years was 0.56.4, 0.72.4, and 0.59.8, respectively. CONCLUSIONS: The Iranian Ministry of Health is expected to design strategies to improve the status of vitamin D at the national level.

Use of sterile fly larvae (maggots) of blow flies for the treatment of many different types of skin and soft tissue wounds is called Maggot debridement therapy (MDT). The larvae of blow flies secrete a broad spectrum of compounds with diverse mechanisms of action in the gut and salivary glands called excretion/secretion (ES) products which showed to have antimicrobial activities against Gram negative and positive bacteria. Cutaneous leishmaniasis (CL) which is the common form of leishmaniasis is difficult to treat. In this study, the effect of ES from 2nd and 3rd stages of L. sericata and C. vicina larvae on in vitro Leishmania major amastigote growth in macrophage was evaluated. The effect of ES on Leishmania growth was estimated by assessing the rate of macrophage infection and the number of amastigotes per infected macrophages. In addition, the anti Leishmania activities of larval and ES of L. sericata and C. vicina on the skin lesion induced by L. major infection was evaluated in susceptible BALB/c mice. The results showed that ES of both flies reduced the number of infected macrophages; 2.6 and 1.5-fold using L. sericata ES and C. vicina ES, respectively, and inhibited amastigotes growth in macrophages; 2.03 and 1.36-fold by L. sericata ES and C. vicina ES, respectively as compared to the control group. The results showed that L. sericata ES was significantly more effective than C. vicina ES to inhibit in vitro L. major amastigotes growth, The size of lesion was significantly smaller in BALB/c mice treated with L. sericata ES than treated with C. vicina ES. The results of in vivo experiments suggested that pre-treatment with ES derived from L. sericata may have some protective effects on the development of L. major lesion. Therefore, it seems that maggot ES might be considered as a possible candidate for the treatment of cutaneous leishmaniasis.
