Abstract
Context
There is still controversy over the effect of vitamin D3 supplementation on bone health.
Objective
The effects of vitamin D3 supplementation on bone mineral density (BMD) and markers of bone turnover, as well as the dose-response relationship between vitamin D3 and bone health in adults, were evaluated.
Data Sources
The PubMed, Scopus, Cochrane, Web of Science, and AGRIS databases were searched for articles published through April 30, 2022. Thirty-nine of the 6409 records identified met the inclusion criteria
Data Extraction
Data were extracted from articles by 2 authors, and data extraction was cross-checked independently. A random-effects model was used to estimate the pooled effect size and the associated 95%CI for the effect of vitamin D3 for each outcome. A one-stage random-effects dose-response model was used to estimate the dose-response relationship between vitamin D3 supplementation and BMD.
Data Analysis
Results of meta-analysis showed a beneficial effect of vitamin D3 at the lumbar spine (standardized mean difference [SMD] = 0.06; 95%CI, 0.01–0.12) and femoral neck (SMD = 0.25; 95%CI, 0.09–0.41). Dose-response analysis revealed a linear relationship between vitamin D3 supplementation doses and BMD at the femoral neck, lumbar spine, and total hip sites. No significant effect of vitamin D3 supplementation on whole-body or total hip BMD was observed (P > 0.05). Vitamin D3 supplementation significantly decreased BMD at both proximal and distal forearm (SMD = −0.16; 95%CI, −0.26 to −0.06). The variables of ethnicity, age, baseline 25-hydroxyvitamin D (25[OH]D), menopause status, vitamin D3 dosing frequency, and bone health status (P interaction = 0.02) altered the effect of vitamin D3 supplementation on BMD. Additionally, a nonlinear relationship between vitamin D3 supplement doses and markers of bone turnover was found.
Conclusion
A protective effect of vitamin D3 supplementation on BMD of the lumbar spine, femoral neck, and total hip is implicated.

Abstract
Background
Meningiomas are one of the most common tumors of the brain and central nervous system. The key role of endocan in predicting tumor growth and prognosis has been shown for several types of cancers; however, this role in meningiomas has not been evaluated. In the current study, we investigated the relationship between endocan serum levels with low- and high-grade meningiomas.
Results
The serum level of endocan in the group with meningiomas was 283.34 (242.09-358.70) pg/ml and in the control group was 250.29 (207.56-329.71) pg/ml respectively (P = 0.172). Afterwards, patients were divided into three different groups (grades I, II, and III) and compared to the control. The level of endocan in the group with grade I of meningioma showed no significant difference compared to control individuals (P = 0.86). When patients with grade II and grade III compared with the control group, endocan serum levels were statistically significant (P = 0.002, P < 0.001 respectively). Moreover, our findings showed that the different grades of meningiomas were statistically significant compared to each other (P < 0.001) regarding endocan serum levels, meaning that the higher the grade, the higher the endocan serum levels.
Conclusion
Our findings revealed that higher grades of meningioma had higher endocan serum levels, however, the role of endocan in pathogenesis or progression of this type of tumor requiring further exclusively assessment.

Abstract
BACKGROUND Acute hepatitis A is usually a self-limited viral disease but can be severe and even fatal in special groups of patients including those with chronic liver disease and recipients of liver transplantation. To take appropriate preventive measures, it is important to determine the immune status against the hepatitis A virus in patients at risk of grave clinical outcomes following infection. To assess the need for immunization against hepatitis A, we aimed to determine the immune status against hepatitis A in a population of liver transplant recipients. We also investigated the association between hepatitis A immune status and demographic factors such as age and sex, underlying liver disease, source of drinking water, geographical area of residence and socioeconomic status. METHODS This cross-sectional study was performed on 242 recipients of allogenic liver transplants at Abu Ali Sina Organ Transplant Hospital in Shiraz, Iran, between January 2017 and April 2017. The level of immunity was assessed using hepatitis A antibody detection kits. RESULTS The rate of immunity against hepatitis A was detected as 88.8% in our study population. In the multivariable logistic regression model, younger age (OR=1.175, P<0.001) and higher education level (OR=2.142, P=0.040) were the main determinants of non-immune status. However, hepatitis A immunity was independent of gender, monthly family income, water supply source, residential area and underlying liver disorder. CONCLUSION Although a significant proportion of liver transplant recipients in this study showed evidence of natural immunity to hepatitis A, a considerable proportion of younger patients and those with a higher level of education were non-immune. The results of this study signify the importance of screening for hepatitis A immunity in this at-risk population of patients and the need for vaccinating non-immune patients.

Abstract
BACKGROUND Dietary patterns may be an important predictor of breast cancer risk. However, they cannot completely explain the pairwise correlations among foods. The purpose of this study is to compare food intake networks derived by Gaussian Graphical Models (GGMs) for women with and without breast cancer to better understand how foods are consumed in relation to each other according to disease status. METHODS A total of 134 women with breast cancer and 267 hospital controls were selected from referral hospitals of Tehran, Iran. Dietary intakes were evaluated by using a validated 168 food-items semi-quantitative food frequency questionnaire. GGMs were applied to log-transformed intakes of 28 food groups to construct outcome-specific food networks. RESULTS Among cases, a main network containing intakes of 12 central food groups (vegetables, fruits, nuts and seeds, olive oil and olive, processed meat, sweets, salt, soft drinks, fried potatoes, pickles, low-fat dairy, pizza) was detected. In controls, a main network including six central food groups (liquid oils, vegetables, fruits, sweets, fried potatoes and soft drinks) was identified. CONCLUSIONS The findings of this study revealed a difference in GGM-identified networks graphs between cases and controls. Overall, GGM may provide additional understanding of relationships between diet and health.

Abstract
BACKGROUND Studying entire dietary patterns is a promising alternative approach to overcome limitations of the single food or nutrient approach. We evaluated the relationship between the scores of 4 established Dietary Approaches to Stop Hypertension (DASH) diet indexes and breast cancer risk among Iranian women. METHODS This case-control study was carried out on 408 eligible women (136 cases and 272 hospital-based controls). A validated 168 item semi-quantitative food frequency questionnaire was used for assessing usual dietary intakes. DASH index scores were generated based on predefined algorithms for each of the 4 previously described indexes (Dixon's, Mellen's, Fung's and Günther's DASH diet index). Unconditional logistic regression analysis was performed to estimate odds ratio (OR) and 95% confidence intervals (CIs) for score categories or quintiles of DASH diet indexes and breast cancer risk in multivariate adjusted models. RESULTS Women in the highest categories of the Mellen's and Günther's scores had lower odds of breast cancer than those in the lowest quintiles (Mellen's OR:0.50; 95% CI:0.62-0.97; P-trend:0.02; Günther's OR:0.48; 95% CI:0.25-0.93; P-trend:0.05). However, no significant associations were found between Dixon's and Fung's DASH score and breast cancer risk. Modification by menopausal status revealed that breast cancer risk was only reduced in postmenopausal women with higher scores on Mellen's index (OR:0.24; 95% CI:0.08-0.68; P-trend:0.04). CONCLUSION A greater adherence to 2 of the 4 DASH indexes (Mellen's and Günther's indexes) was associated with decreased risk of breast cancer.

Abstract
The mammalian target of rapamycin (mTOR) is a protein kinase that has been considered as a key regulator of a large number of cellular processes, including cell growth, proliferation, differentiation, survival, and motility. Overactivation of mTOR (especially mTORC1) signaling is related to oncogenic cellular processes. Therefore targeting mTORC1 signaling is a new promising strategy in cancer therapy. In this regard, various studies have shown that curcumin, a polyphenol produced from the turmeric rhizome, has anti-inflammatory, antioxidant and anticancer properties. Curcumin may exert its anticancer function, at least in part, by suppressing mTOR-mediated signaling pathway in tumor cells. However, the exact underlying mechanisms by which curcumin blocks the mTORC1 signaling remain unclear. According to literature, curcumin inhibits insulin-like growth factor 1 (IGF-1)/phosphoinositide 3-kinase (PI3K)/Akt/mTORC1 pathway which leads to apoptosis and cell cycle arrest via suppression of erythroblastosis virus transcription factor 2 and murine double minute 2 oncoprotein. In addition, activation of unc-51-like kinase 1 by curcumin, as a downstream target of IGF-1/PI3K/Akt/mTORC1 axis, enhances autophagy. Curcumin induces AMP-activated protein kinase, a negative regulator of mTORC1, via inhibition of F0F1-ATPase. Interestingly, curcumin suppresses IκB kinase β, the upstream kinase in mTORC1 pathway. Moreover, evidence revealed that curcumin downregulates the E3-ubiquitin ligases NEDD4, neural precursor cell-expressed developmentally downregulated 4. NEDD4 is frequently overexpressed in a wide range of cancers and degrades the phosphatase and tensin homolog, which is a negative regulator of mTORC1. Finally another suggested mechanism is suppression of MAOA/mTORC1/hypoxia-inducible factor 1α signaling pathway by curcumin.

Abstract
OBJECTIVE Food intake for its hedonic properties can result in excess caloric intake. It may play a role in increasing trend of obesity in the world. Hedonic hunger may effect on dietary patterns. We assessed the association between dietary patterns and the hedonic score in obese and non-obese women. In this case-control study 140 women aged 17-44 years from an obesity club at district 4 of Tehran participated. Dietary patterns were assessed through food frequency questionnaire by factor analysis method. The hedonic score was determined using a 21-item valid questionnaire. ANOVA and Logistic regression were used to statistical analysis. RESULTS Factor analysis method showed that there were 2 dietary patterns named healthy and unhealthy, in order to their food items. There was not any significant trend for obesity among tertiles of healthy and unhealthy dietary patterns. The mean hedonic score was significantly higher in obese than non-obese women, (p < 0.05). The second and the third tertiles of hedonic score significantly increase the odds of obesity referring the first tertile (2.8 and 10.8, respectively). Hedonic hunger had a positive association with obesity; but there was no difference in dietary patterns of obese and non-obese women, unexpectedly.

Abstract
Background: This study aimed to assess the effects of Gluten free diet (GFD) on components of metabolic syndrome (MES). Materials and Methods: In this randomized clinical trial, 50 subjects diagnosed with MES were randomly divided into two groups (n=25). The first group received a GFD and the second group continued their regular diet. Biochemical markers of MES and blood pressure were measured before and after 8-week intervention. Results: Forty five subjects completed the study. A post-hoc comparison of the groups showed no effects of the GFD and control diet on LDL cholesterol, total cholesterol, fasting insulin, HOMA-IR, systolic and diastolic blood pressure levels. The GFD reduced fasting blood glucose, waist circumference (WC) and serum triglyceride concentration significantly compared with the control diet (p<0.05). Conclusion: Short-term GFD reduced WC and improved glycemic control and Triglyceride level in subjects with the metabolic syndrome.

Abstract
BACKGROUND The role of dietary quality indexes for predicting breast cancer (BrCa) risk remains inconclusive. We aimed to assess the relation between healthy eating index 2010 (HEI-2010) and BrCa risk in a case-control study in Iranian women. METHOD The 272 hospitalized controls and 136 newly diagnosed BrCa cases were recruited from two major hospitals. Food frequency questionnaire (FFQ) data were then utilized to calculate the HEI-2010 scores. Logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CIs) between tertiles of HEI-2010 and BrCa risk, adjusting for potential confounders. RESULTS We found that higher HEI-2010 scores were associated with lower risk of BrCa only among premenopausal women (multivariate adjusted OR= 0.27, 95% [CI]: 0.10-0.69; P for trend =0.02). However, this inverse association was not the results of a link with any specific component of the HEI-2010. Among postmenopausal women, lower intake from empty calories was associated with lower risk of BrCa by 13% (OR =0.87, 95% CI: 0.77-0.99). CONCLUSION Our findings suggest that adherence to HEI-2010 might be associated with lower risk of BrCa only among premenopausal women.

Abstract
Objective: To explore the role of nutrient patterns in the etiology of breast cancer (BCa) among Iranian women. Methods: The study included 134 newly diagnosed cases of BCa and 267 hospitalized controls. A validated semi-quantitative food frequency questionnaire (FFQ) was used to assess dietary intake. Nutrient patterns were obtained using principal component analysis using Varimax rotation and logistic regression was performed to estimate breast cancer risk. Results: We identified 4 major nutrient patterns. First was high in consumption of vitamins B1, B2, B3, B5, B6, B9, C, magnesium, iron, carbohydrate, fiber, selenium, zinc, protein, potassium, and calcium. The second nutrient pattern included Vitamins B12, A and cholesterol, while the third featured vitamin D, EPA and DHA. The fourth was characterized by vitamin E, MUFA and saturated fatty acids. After adjusting for age, patterns 1 and 3 were associated with a lower risk of BCa (OR=0.51, 95% CI: 0.33- 0.80, P=0.003, OR=0.64, 95% CI: 0.42- 0.98, P= 0.04 respectively). However, after further adjustment for all confounders in multivariate analysis, the association remained significant only for pattern 1 (OR=0.52, 95% CI: 0.32- 0.82, P=0.006). Conclusion: Adherence to a nutrient pattern rich in vitamin B, minerals and fiber is associated with a lower risk of breast cancer.

Abstract
AIM Breast cancer is the most common cancer among women worldwide. Most previous studies focused on individual nutrients or foods rather than overall dietary patterns. We aimed to assess the association between major dietary patterns and breast cancer risk. METHOD In a hospital-based case-control study, 134 women diagnosed as breast cancer and 267 controls were recruited from referral hospitals in Tehran, Iran. Dietary intakes were evaluated by using a validated 168-item food frequency questionnaire. Dietary pattern were identified by factor analysis. Odds ratios (OR) were estimated using logistic regression. RESULTS Two dietary patterns were extracted: healthy and unhealthy. The "Healthy" dietary pattern was loaded for high consumptions of fruits, vegetables, seeds, legume, fish and sea foods, whole grains, liquid oils, olive oils and olive and lack of salt intake. "Unhealthy" dietary pattern was characterized by high factor loadings for sweets, soft drinks, mayonnaise, solid oils, processed meat, fried and boiled potato and salt intake. In multivariate logistic regression analyses, the healthy dietary pattern was not associated with breast cancer risk (OR: 0.83; 95%CI: 0.36, 1.89; P-trend = 0.50), while women in the highest quartile of the unhealthy dietary pattern had a significantly increased breast cancer risk (OR: 2.21; 95%CI: 1.04, 4.690; P-trend = 0.009). When stratified by menopausal status, unhealthy dietary pattern showed inverse association with breast cancer risk only among post-menopausal women (OR: 3.56; 95%CI: 1.16, 10.95; P-trend = 0.008). CONCLUSIONS Our findings showed that an unhealthy dietary pattern might be associated with higher risk of breast among Iranian women.

Abstract
Background In Iran, colorectal cancer (CRC) is the third and fourth leading cause of cancer incidence among men and women, respectively. Diet and inflammation have been suggested as important risk factors for CRC. We examined the association between dietary inflammatory index (DII) scores and CRC in a case-control study conducted in Iran. Methods This study included 71 CRC cases and 142 controls hospitalized for acute non-neoplastic diseases. DII scores were computed from dietary intake assessed by a previously validated food frequency questionnaire. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CI) adjusted for age, sex, education, energy intake, exercise, body mass index (BMI), smoking, family history of cancer, and history of aspirin, acetaminophen, and multivitamin use. Results Subjects with higher DII scores (i.e., indicating a more pro-inflammatory diet) had a higher odds of CRC with the DII being used as both a continuous variable (OR continuous = 2.20, 95% CI: 1.22-3.87) and as a categorical variable (OR tertile 3 vs tertile1 = 2.47, 95%CI: 1.10-5.55). Conclusion These results indicate that a pro-inflammatory diet is associated with increased odds of CRC in this Iranian population.

Abstract
Background Given the high prevalence of overweight and obesity in Iran, identification of a healthy diet is essential. Objective This study aimed to assess the association between adherence to a Mediterranean diet and overweight and obesity in female adolescents. Methods Two hundred and eighty female adolescents from high schools in Tehran were recruited. General information, physical activity and food frequency questionnaires were completed. Adherence to the Mediterranean diet was evaluated using the Mediterranean Style Dietary Pattern Score (MSDPS). Results Under and over reporters of energy intake were excluded from the analysis (n = 37). Results indicated that prevalence of overweight and obesity was 13.3% and 12.5%, respectively. The mean of MSDPS was low in this population (15.99 ± 5.64). The MSDPS was positively associated with mother's education level and energy intake (p < 0.05). No significant relation was observed between MSDPS and overweight and obesity among adolescents. However, there was a negative significant association between MSDPS and WHR just among students who had educated mothers [high: second median v. low: first median, odds ratio (OR) = 0.36, 95% confidence interval (CI) = 0.12-1.03]. Conclusion Adherence to a Mediterranean dietary pattern is low among adolescent females in Tehran, with no association with overweight and obesity.

Abstract
AIM To assess the relation between nutrient patterns and cataract risk. METHODS This is a hospital-based case-control study with 97 cataract patients and 198 matched controls. Dietary consumption was collected through a valid food frequency questionnaire (FFQ). Nutrient patterns were detected by applying factor analysis. Unconditional logistic regression models were used to estimate odds ratio (ORs) and 95%CIs. RESULTS We extracted 5 main nutrient patterns. Factor 1 included niacin, thiamin, carbohydrates, protein, zinc, vitamin B6 and sodium (sodium pattern). Factor 2 was characterized by oleic acid, monounsaturated fats, polyunsaturated fats, linoleic acid, trans fatty acid, linolenic acid, vitamin E and saturated fats (fatty acid pattern). The third factor represented high intake of vitamin B12, vitamin D, cholesterol and calcium (mixed pattern). The 4th pattern was high in intake of beta and alpha carotene, vitamin A and vitamin C (antioxidant pattern). Finally, the 5th pattern loaded heavily on docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) (omega-3 pattern). In crude and multivariate analysis, the sodium pattern was associated with increased risk of cataract (OR=1.97, 95%CI: 1.09-3.96). The fatty acid pattern elevated the risk of cataract (OR=1.94, 95%CI: 1.1-3.86). Antioxidant pattern was associated with a significant 79% reduced risk (2nd category compared with the 1st). Omega-3 pattern was significantly negatively associated with risk of cataract (P=0.04). CONCLUSION These findings imply that nutrient patterns reflecting a combined consumption of nutrients might be important in the etiology of cataract. Additional studies with more efficient designs are warranted to confirm our findings.

Abstract
BACKGROUND Maternal dietary patterns play an important role in the progress of gestational diabetes mellitus (GDM). The aim of the present study was to explore this association. METHOD A total of 388 pregnant women (122 case and 266 control) were included. Dietary intake were collected using a food frequency questionnaire (FFQ). GDM was diagnosed using a 100-gram, 3-hour oral glucose tolerance test. Dietary pattern was identified by factor analysis. To investigate the relation between each of the independent variables with gestational diabetes, the odds ratio (OR) was calculated. RESULTS Western dietary pattern was high in sweets, jams, mayonnaise, soft drinks, salty snacks, solid fat, high-fat dairy products, potatoes, organ meat, eggs, red meat, processed foods, tea, and coffee. The prudent dietary pattern was characterized by higher intake of liquid oils, legumes, nuts and seeds, fruits and dried fruits, fish and poultry whole, and refined grains. Western dietary pattern was associated with increased risk of gestational diabetes mellitus before and after adjustment for confounders (OR = 1.97, 95% CI: 1.27-3.04, OR = 1.68, 95% CI: 1.04-2.27). However, no significant association was found for a prudent pattern. CONCLUSION These findings suggest that the Western dietary pattern was associated with an increased risk of GDM.

Abstract
BACKGROUND AND OBJECTIVES We conducted a hospital-based, case-control study to examine the association between Mediterranean diet (MD) and the risk of multiple sclerosis (MS) in Iran. METHODS AND STUDY DESIGN A total of 70 patients with MS and 142 controls underwent face-to-face interviews in the major neurological clinics of Tehran, Iran. Adherence to a MD was assessed using the 9-unit dietary score, to evaluate the level of conformity of the individual's diet to the Mediterranean dietary pattern. Multivariate logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI). RESULTS Higher consumption of fruits (OR=0.28, 95% CI: 0.12-0.63, p-value: 0.002) and vegetables (OR=0.23, 95% CI: 0.10-0.53, p-value: 0.001) were significantly associated with reduced MS risk. In both age adjusted and multivariate adjusted model, the OR of MS decreased significantly in the third as compared to the first tertile of MD score (age adjusted OR: 0.21, 95% CI: 0.06-0.67; p-trend: 0.01, Multivariate adjusted OR: 0.23, 95% CI: 0.06-0.89, p-trend: 0.04). CONCLUSIONS Our study suggests that a high quality diet assessed by MD may decrease the risk of MS.

Abstract
Since clinical manifestations of most febrile infants younger than three months old are nonspecific, differentiation of Serious Bacterial Infection (SBI) from self-limiting viral illness is a significant challenge for pediatricians. This study was performed to assess the diagnostic value of white blood cell count (WBC), Absolute Neutrophil Count (ANC), Interleukin -6 (IL-6) and C-reactive protein (CRP) level to predict SBI in febrile infants younger than three months old who were hospitalized. This was a diagnostic test validation study. In this prospective study, 195 febrile infants admitted to 17 Shahrivar Hospital underwent a full sepsis workup including blood, urine, cerebrospinal fluid cultures and chest radiography. WBC count, ANC and CRP and Il-6 level were measured in all patients. Serum IL-6 concentration was measured by Enzyme-linked Immunosorbent Assay test. Then diagnostic, values of these tests for predicting SBI was compared with each other. Of total cases, 112 (57.4%) infants were male. SBI was diagnosed in 29 (14.9%) patients. The most common type of SBI was Urinary Tract Infection (UTI). Serum IL-6 (³20pg/dl) had sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 79/1%, 91.6%,75.4%, 60.3%, respectively and for CRP (³ 10mg/l) values were 81.6%, 89.8%, 78.2%, and 52%,respectively. The predictive values of CRP and IL-6 were higher than WBC and ANC. IL-6 and CRP are more valid and better diagnostic markers for predicting SBI than WBC count and ANC. CRP level seems to be an accessible and cost-effective marker for early diagnosis of SBI. Since by no marker we can totally rule out SBI in febrile infants < three months of age, it is recommended to administer systemic antibiotics until culture results become available.

Abstract
Visceral leishmaniasis (VL) is a serious health problem in Iran. The disease is mainly transmitted by sand fly bites, but its transmission through transfusion in endemic areas may also occur. The current study aimed to determine the prevalence of Leishmania infection among blood donors in VL-endemic areas in south of Iran. A total of 2003 healthy blood donors from blood service centers in five VL-endemic districts in Fars province, southern Iran, were enrolled in the study. The blood samples were assessed for antibodies against Leishmania infantum by direct agglutination test (DAT). Seropositive subjects were tested for the presence of L. infantum DNA in their buffy coat by the molecular method. Socio-demographic features of the subjects were also documented during sample collecting. The mean age of participants was 36.3 (SD = 10.7 years). Male constituted 94.7 % of the subjects while only 5.3 % of donors were female. Twenty-eight blood donors (1.4 %) were positive for Leishmania infection by DAT. Only one of these seropositive donors was positive for Leishmania infection by polymerase chain reaction. A significant correlation was found between age, the place of residence and seropositivity to Leishmania (P < 0.05). Findings of this study revealed that the prevalence of Leishmania infection among blood donors in transfusion centers in the VL-endemic areas in Iran is relatively high. These asymptomatic blood donors may constitute a risk of transmitting of VL to susceptible recipients.

Abstract
Cystic echinococcosis is a zoonotic infection of humans and domestic animals caused by the larval stages of the cestode Echinococcus granulosus. Cystic echinococcosis is one of the most important zoonotic diseases in Iran, where human cases are frequently reported from different regions of the country. The objective of this study was to determine the sero-epidemiological and surgical cases of human hydatidosis in the Yasuj district, a region in southwest of Iran. Serum samples were taken from 500 individuals attending Yasuj health centers. Anti-hydatid cyst antibody was checked by enzyme-linked immunosorbent assay (ELISA), using antigen B. Moreover, retrospective studies were carried out using local hospital records of CE patients between 1997 and 2006. Results of the sero-epidemiological study showed that 36 out of 500 cases (7.2%) have antibody against hydatid cyst. Of these 36 cases, 49.6% were women and 50.4% were men. The highest rate of infection was recorded in individuals aged between 30 and 39 years. Hospital records showed that during the 10 years, 105 cases of hydatidosis were admitted in Yasuj hospitals. Of all cases, 70 (66.7%) were women and 35 (33.3%) were men. Hepatic cyst was recorded in 81% of the cases where nephrotic cysts were the second most prevalent ones. Recurrence of the disease was noted in 14.3% of all cases. Results of this study demonstrated that hydatidosis is an important endemic disease, with a nearly constant prevalence rate during the last 10 years, in Yasuj district in Iran. Further studies are needed to investigate the reasons for high rate of surgical cases in housewives and striking prevalence of hydatidosis in a specific (30-40 years) age group.

Abstract
The members of the S100 protein family are multifunctional proteins with a regulatory role in a variety of cellular processes. They exert their actions usually through calcium binding, although Zn2+ and Cu2+ have also been shown to regulate their biological activity. The most studied member, protein S100B, exhibits neurotrophic (at physiologic concentration) or neurotoxic (at higher concentration) activity and its immunohistochemical expression or serum levels have been determined in various clinical disorders. S100B has been well documented as a marker of astrocytic activation mediating its effects via interaction with receptor for advanced glycation end products (RAGE). We herein provide a wide range of information concerning their clinical application in traumatic brain injuries, Alzheimer disease, subarachnoid haemorrhage and other neurologic disorders, malignant melanoma and several other neoplasms (as S100B has been shown to down-regulate p53), as well as inflammatory diseases. Also its use on predicting neurologic outcome after resuscitation for cardiac arrest or in intrauterine growth retardation newborns is discussed.
