Abstract
CONTEXT Low serum albumin and pre-albumin concentrations are associated with edema, infection, thrombosis, heart failure, and mortality. OBJECTIVE This comprehensive systematic review and meta-analysis of clinical trials was conducted to summarize the available findings on the impact of omega-3 supplementation on albumin, pre-albumin, and the C-reactive protein/albumin ratio in hospitalized patients. DATA SOURCES PubMed, Web of Science, Scopus, and Google Scholar databases were searched from January 1990 to October 2021. DATA EXTRACTION Extracted data from 50 randomized controlled trials (RCTs) with a total number of 3196 participants were analyzed using the random-effects model. The dose-dependent effect was also evaluated. DATA ANALYSIS Oral omega-3 supplementation significantly increased serum albumin concentrations in patients with cancer (weighted mean difference [WMD]: 0.19; 95% CI: 0.05, 0.33, P= 0.006), patients on dialysis (WMD: 0.14; 95% CI: 0.01, 0.28, P= 0.042), and those with hypoalbuminemia (WMD: 0.38; 95% CI: 0.03, 0.72, P = 0.033); however, there was no significant effect among patients with gastrointestinal or hepatologic diseases. Moreover, each 1000 mg/day increase in oral omega-3 supplementation resulted in elevated serum albumin levels in cancer patients (WMD: 0.15; 95% CI: 0.07, 0.24, P < 0.001). In addition, a favorable effect of oral omega-3 supplementation on pre-albumin levels was observed among patients with cancer (WMD: 33.87; 95% CI: 12.34, 55.39, P = 0.002). A similar significant effect of parenteral omega-3 supplementation on pre-albumin concentrations was seen among those with gastrointestinal and hepatologic diseases as well (WMD: 23.30; 95% CI: 13.58, 33.03, P < 0.001). No significant effect of oral omega-3 supplementation on the CRP/albumin ratio was found. CONCLUSIONS Overall, omega-3 fatty acids supplementation resulted in a favorable change in serum albumin and pre-albumin concentrations in hospitalized patients.

Abstract
Objective Lifestyle interventions are increasingly becoming an integrated part of nonalcoholic fatty liver disease (NAFLD) management. Electronic lifestyle interventions may be able to expand the access and utility of this approach. This study aimed to synthesize the evidence for the effects of electronic-based lifestyle interventions on weight, anthropometric, and liver enzyme measurements in patients with NAFLD. Methods Medline, Scopus, and Web of Science were searched up to February 2023. Clinical trials investigating the effects of electronic lifestyle interventions on weight, body mass index (BMI), waist circumference (WC), and liver enzymes in NAFLD patients were reviewed. After reviewing full-text articles, seven clinical trials were included in the systematic review. Results Two articles included telephone calls, one was based on text messaging, two studies were based on web-based lifestyle modifications, and two used mobile apps. Except for one, all other six studies indicated a significant impact on weight loss. BMI was reported in six of seven studies. Except for one, BMI was significantly reduced in the group receiving e-health. WC was reported in four studies, which indicated a significant reduction in the e-health intervention group. Alanine transaminase (ALT) was reported in all the included studies. Except for two, others demonstrated a significant improvement in ALT in the e-health intervention groups. As reported in four studies, Aspartate transaminase (AST) significantly decreased in the group receiving e-health interventions, except in one study. Conclusions The results support applying electronic lifestyle interventions in NAFLD patients to reduce weight, BMI, WC, AST, and ALT.

Abstract
OBJECTIVES This study aimed to summarise the effect of community-based intervention programmes on the prevention of cardiovascular disease (CVD) by reducing cardiometabolic risk factors. STUDY DESIGN This was a systematic review and meta-analysis. METHODS A systematic search in the PubMed database and screening of reference lists aimed to identify community-based CVD prevention programmes from inception up to April 2020. The mean differences and standard deviations for CVD risk factors, including blood pressure, lipid profile, blood glucose and body weight indices, were extracted and pooled using a random effects model. RESULTS Screening of 11,889 titles/abstracts and full texts resulted in 48 studies being included in this review. The meta-analysis showed that community-based programmes have led to considerable decreases in systolic blood pressure (weighted mean difference [WMD] = -2.90 mm Hg, 95% confidence interval [95% CI]: -3.63, -2.16), diastolic blood pressure (WMD = -2.21 mm Hg, 95% CI: -3.12, -1.29), serum levels of low-density lipoprotein cholesterol (LDL-C; WMD = -8.88 mg/dl, 95% CI: -12.84, -4.92), triglycerides (WMD = -8.40 mg/dl, 95% CI: -12.10, -4.70), total cholesterol (WMD = -2.96 mg/dl, 95% CI: -3.10, -2.81) and fasting blood glucose (WMD = -2.06 mg/dl, 95% CI: -3.02, -1.10). A moderate decrease in body weight was also found with community-based CVD prevention programmes. However, community-based CVD prevention programmes were not associated with any significant changes in serum levels of high-density lipoprotein. CONCLUSIONS The present study indicates that community-based strategies have successfully led to an improvement in CVD risk factors, particularly by reducing blood pressure, serum levels of LDL-C and triglycerides, obesity indices and blood glucose. The impact of these programmes on CVD is modified by the type of intervention and by different cultural and physical environments.

Abstract
The pandemic of severe acute respiratory syndrome coronavirus 2 raised the attention towards bacterial coinfection and its role in coronavirus disease 2019 (COVID-19) disease. This study aims to systematically review and identify the pooled prevalence of bacterial coinfection in the related articles. A comprehensive search was conducted in international databases, including MEDLINE, Scopus, Web of Science, and Embase, to identify the articles on the prevalence of bacterial coinfections in COIVD-19 patients from 1 December 2019 until 30 December 2020. All observational epidemiological studies that evaluated the prevalence of bacterial coinfections in patients with COVID-19 were included without any restriction. Forty-two studies including a total sample size of 54,695 were included in the analysis. The pooled estimate for the prevalence of bacterial coinfections was 20.97% (95% CI: 15.95-26.46), and the pooled prevalence of bacterial coinfections was 5.20% (95% CI: 2.39-8.91) for respiratory subtype and 4.79% (95% CI: 0.11-14.61) for the gastrointestinal subtype. The pooled prevalence for Eastern Mediterranean Regional Office and South-East Asia Regional Office was 100% (95% CI: 82.35-100.00) and 2.61% (95% CI: 1.74-3.62). This rate of coinfection poses a great danger towards patients, especially those in critical condition. Although there are multiple complications and adverse effects related to extensive use of antibiotics to treat patients with COVID-19, it seems there is no other option except applying them, and it needs to be done carefully.

Abstract
BACKGROUND & OBJECTIVES Earlier published studies on maternal caffeine intake during pregnancy in relation to the risk of low birth weight (LBW) (birth weight <2500 g) have indicated conflicting findings. Therefore, the present systematic review and meta-analysis was conducted to examine the association between maternal caffeine intake and risk of LBW. METHODS We searched for relevant articles published up to Jan 2021 through PubMed and Scopus. For this purpose, we used MESH (Medical Subject Heading) and non-MESH keywords. Cohort studies that considered maternal caffeine intake as the exposure variable and LBW as the main outcome variable were included in the systematic review. Finally, seven cohort studies were considered in this systematic review and meta-analysis. RESULTS Combining seven effect sizes, we found a significant positive association between maternal caffeine intake and risk of LBW (RR: 1.70; 95% CI: 1.19-2.43). We also found that each additional 100-mg per day of maternal caffeine intake was significantly associated with an increased risk of LBW (RR: 1.12; 95% CI: 1.03-1.22; Pheterogeneity = 0.020). In addition, nonlinear dose-response analysis showed a significant relationship (Pnonlinearity < 0.001) between maternal caffeine intake and risk of LBW. CONCLUSIONS In this systematic review and meta-analysis, we found a significant positive association between maternal caffeine intake and risk of LBW.

Abstract
Background Limited and inconsistent data are available regarding the relationship between the dietary inflammatory potential (DIP) and risk of gestational diabetes mellitus (GDM). Objective The present prospective study aimed to evaluate the association between DIP score during the first trimester of pregnancy and risk of developing GDM among Iranian women. Methods In this prospective cohort study, 812 pregnant women aged 20–40 years, who were in their first trimester, were recruited and followed up until week 24–28 of gestation. Dietary intakes of study subjects were examined using an interviewer-administered validated 117-item semi-quantitative food frequency questionnaire (FFQ). DIP score was calculated from 29 available food parameters based on earlier literature. The results of a fasting plasma glucose concentration and a 50-g, 1-h oral glucose tolerance test, between the 24th and 28th week of gestation, were used to diagnose GDM. The risk of developing GDM across quartiles of DIP score was estimated using Cox regression in several models. Results At study baseline, mean (SD) age and BMI of study participants were 29.4 (±4.84) y and 25.14 (±4.08) kg/m2, respectively. No significant association was found between DIP score and risk of GDM in the crude model (RR: 1.01; 95% CIs: 0.71–1.45). When we adjusted for age the association did not alter (RR: 1.04; 95% CIs: 0.72–1.48). Even after further adjustment for maternal weight gain we failed to find a significant association between DIP score and risk of GDM (RR: 0.97; 95% CIs: 0.66–1.41). Conclusion We found no significant association between DIP and risk of developing GDM. Further longitudinal studies among other populations are needed to elucidate the association between DIP score and GDM.

Abstract
Background: Sarcopenia has rarely been linked to Food-based Inflammatory Potential of the Diet (FIPD) in earlier studies. This study was performed to examine the association of FIPD and sarcopenia and its components. Method: In the cross-sectional research, dietary intakes of 300 randomly-selected elderly adults aged 55 years or older were collected through a validated food frequency questionnaire. We constructed FIPD score based on average consumptions of 28 food items. According to The European Working Group on Sarcopenia definition, sarcopenia and its components such as muscle strength, muscle mass, and gait speed were defined. Result: No significant difference was found between the prevalence of sarcopenia (P = 0.05), low muscle mass (P = 0.27), low handgrip strength (P = 0.72), and lower gait speed (P = 0.14) across tertiles of FIPD score. Moreover, we did not find significant differences among means of handgrip strength (P = 0.65), muscle mass (P = 0.33), and walking speed (P = 0.89) across FIPD categories. However, binary logistic regression analysis indicated a significant positive relationship between FIPD score and odds of sarcopenia; such that subjects in the top vs. those in the bottom FIPD tertile had 155% greater chance of having sarcopenia (OR: 2.55; 95% CI: 1.17-5.55). After controlling for all confounding factors, this association strengthened (OR: 2.67; 95% CI: 1.18-6.01). Conclusion: We found that greater FIPD score, which means a more pro-inflammatory diet, was positively linked with sarcopenia.

Abstract
The study aims to develop a novel nanohybrid shear-thinning hydrogel with fast gelation, and variable mechanical and biological properties. This nanohybrid hydrogel was developed via self-assembly guest-host interaction between β-cyclodextrin modified alginate (host macromere, Alg-CD) and adamantine modified graphene oxide (guest macromere, Ad-GO) and subsequent ionic crosslinking process. We found that the rheological and mechanical properties of hydrogels were controlled via macromere concentration and the host: guest macromere ratio, due to the modulation of crosslinking density and network structure. Noticeably, 12%(1:2) dual-crosslinked hydrogel (2DC12) significantly improved the strength (1.3-folds) and toughness compared to 10%(1:4) dual-crosslinked hydrogel (4DC10). Furthermore, the hydrogel erosion and cytocompatibility relied on the designed parameters. Remarkably, 2DC12 showed less than 20% weight loss after 20 days of incubation in physiological solution and more than 200% cell survival after five days. In conclusion, the nanohybrid Alg-GO hydrogel could be used as an injectable hydrogel for soft tissue engineering applications.

Abstract
BACKGROUND Adolescence is a critical period with respect to mental and psychological issues. The role of nutrients is well known in health condition in adolescents, but little emphasis is placed on total diet quality. Dietary diversity score (DDS) is often used to assess diet quality. The objective of this study was to investigate the relationship between DDS and general health in girl students. METHODS The present research is a cross-sectional study which used descriptive-analytical approach. A total of 384 high-school female students selected using proportional stratified sampling. Physical activity level, diet and general health information collected using International Physical Activity Questionnaire (IPAQ), Dietary Diversity Questionnaire (FAO-2013) and 28-item self-reported general health questionnaire (GHQ-28), respectively. In addition, weight, height and waist circumference (WC) measured. Data analyzed using Chi-Square test, one-way ANOVA and Multinomial Logistic Regression. RESULTS Mean DDS was 4.43±1.09. After adjustment for confounders of age, body mass index, physical activity, socioeconomic status and nutritional supplement intake, students with higher DDS were less prone to general health disorders (P≤0.05). CONCLUSIONS These finding implicate higher DDS in adolescents may associate with better general health.

Background. Two-dimensional (2D) echocardiography is widely accepted method for the assessment of left ventricular (LV) morphology and function after myocardial infarction and for initial preoperative evaluation of patients planned for surgical ventricular repair (SVR). Magnetic resonance imaging and cardiac computer tomography (CT) provide more accurate measurements, but not always available.
Purpose. The aim of this study was to compare 2D-echocardiography and CT for preoperative assessment of patients with LV aneurysm in order to optimize the perioperative management in SVR.
Methods. Patients (n = 179, mean age 62.6 ± 11 years, 23.5% women) with LV anteroapical aneurysm due to myocardial infarction were examined by echocardiography and CT before SVR. LV end-diastolic and end-systolic volumes (LVEDV and LVESV) and ejection fraction (EF) obtained by two methods were compared pairwise. Prognostic role for the prediction of all-cause death was assessed for preoperative parameters in multivariate Cox regression model adjusted for patient age, sex, NYHA class, diabetes mellitus, renal failure, atrial fibrillation and arterial hypertension.
Results. There was a strong correlation for preoperative LVEDV and LVESV measured by echocardiography and CT (r = 0.85, r = 0.87, p < 0.0001), however volumes obtained by echocardiography were smaller compared to those by CT (Table) with higher difference in patients with more dilated LV, as demonstrated by Bland-Altman analysis (Fig.). No significant difference in mean preoperative EF was observed with moderate correlation between two methods (r = 0.67, p < 0.0001). In total 68 patients died during median follow up of 5.3 years (IQR: 1.7-8.7 years) after SVR. Comparable predictive value was demonstrated for LVEDV measured by CT and echocardiography (for 10 ml increase HR = 1.04, p = 0.004 and HR = 1.06, p = 0.0001), as well as for LVESV (for 10 ml increase HR = 1.04, p = 0.001 and HR = 1.07, p = 0.0001) and for EF (for 5% increase HR = 0.83, p = 0.004 and HR = 0.81, p = 0.004).
Conclusion. In patients with LV aneurysm 2D-echocardiography may be used for the assessment of LV volumes and function and have similar prognostic role compared to CT in patients evaluated for SVR. Underestimation of LV volumes by echocardiography must be considered, especially in patients with more dilated LV.

Abstract
Background/Aims Despite huge evidence on the link between adherence to dietary approaches to stop hypertension (DASH) eating pattern and several metabolic abnormalities, the association of this diet with irritable bowel syndrome (IBS) has not been investigated so far. We aim to examine the association between adherence to the DASH diet and prevalence of IBS symptoms and subtypes in adults. Methods This cross-sectional study was done among 3362 adult people in Isfahan, Iran. Usual dietary intakes were assessed using a validated 106-item dish-based semi-quantitative food frequency questionnaire. To investigate participants’ adherence to DASH-style diet, we created DASH score based on 8 main foods and nutrients emphasized or minimized in the DASH diet. Participants were classified into 3 categories according to their DASH-style diet scores. A validated modified Persian version of the Rome III questionnaire was applied for assessment of IBS. Results Totally, 22.2% of study participants were affected by IBS. After adjustment for potential confounding factors, we found that participants in the highest tertile of DASH score had lower odds of IBS (OR, 0.65; 95% CI, 0.50-0.83) compared with those in the lowest tertile. The same findings were also reached for IBS with constipation (OR for the highest vs the lowest tertile of DASH-style diet = 0.56; 95% CI, 0.38-0.85). No significant association was seen between adherence to DASH-style diet and IBS with diarrhea (OR, 1.31; 95% CI, 0.83-2.06). Conclusions We found a significant inverse association between adherence to DASH dietary pattern and odds of IBS and IBS with constipation. Further prospective studies are required to confirm these findings.

Abstract
AIMS This study aimed to investigate the association between dietary GI and GL and risk of GDM in a group of pregnant women in Iran. METHODS A number of 812 pregnant women were recruited in their first trimester in a prospective study. A validated 117-item semi-quantitative food frequency questionnaire was used to assess usual dietary intakes of participants at study baseline. Dietary GI and GL were calculated based on earlier publications. GDM was diagnosed based on the results of a fasting plasma glucose concentration and a 50-g, 1-h oral glucose tolerance test at 24-28 weeks of gestation. Cox proportional hazards model was used to compute relative risks (RRs) and 95% confidence intervals (CI) for GDM. RESULTS Mean ± SD of age and BMI of study participants was 29.4 ± 4.84 y and 25.14 ± 4.08 kg/m2, respectively at study baseline. Mean ± SD of dietary GI was 58 ± 7 and that of dietary GL was 176 ± 42. Overall, 28.4% (n = 231) of study population developed GDM at weeks 24-28 of pregnancy. After adjustment for potential confounding variables, we found that women in the highest tertile of dietary GL were 43% more likely to develop GDM than those in the lowest tertile (95% CI: 1.01, 2.00; P-trend = 0.03). However, no significant association was seen between dietary GI (RR for the highest tertile compared to the lowest: 0.85; 95% CI: 0.61, 1.20; P-trend = 0.37), and risk of GDM. CONCLUSIONS We found that women with the highest dietary GL were at a greater risk of developing GDM during pregnancy. No significant association was seen between dietary GI and risk of GDM.

Abstract
BACKGROUND Despite a large body of evidence on the link between dietary inflammatory index (DII) and several chronic conditions, limited data are available about the association of DII and sarcopenia. This study aimed to examine the relationship between inflammatory potential of the diet (as measured by DII) and sarcopenia and its components among community-dwelling elderly population. METHODS This population-based cross-sectional study was performed in 2011 among 300 elderly people (150 men and 150 women) aged ≥55 years, who were selected using cluster random sampling method. Dietary assessment was done using a pre-tested food frequency questionnaire. Energy-adjusted DII was calculated based on earlier studies. Sarcopenia and its components were determined based on the European Working Group on Sarcopenia (EWGSOP) definition. RESULTS Mean age of study participants was 66.7 ± 7.7 y. Subjects in the highest tertile of DII score (i.e. those with a more pro-inflammatory diet) were more likely to be older (P = 0.02). The prevalence of sarcopenia (P = 0.016) and low muscle mass (P = 0.041) was significantly higher among subjects in the top tertile compared with those in the bottom tertile of DII. After adjustment for potential confounders, those with the highest DII were 2.18 times (95% CI: 1.01-4.74) more likely to have sarcopenia than those with the lowest DII. With regard to components of sarcopenia, subjects in the top tertile of DII had not significantly greater odds of low muscle mass (OR: 1.38; 95% CI: 0.72-2.63), abnormal handgrip strength (OR: 0.97; 95% CI: 0.49-1.89), and abnormal gait speed (OR: 1.61; 95% CI: 0.84-3.08) than those in the bottom tertile. CONCLUSIONS In conclusion, a diet with more pro-inflammatory potential was associated with a greater odds of sarcopenia. Further studies are required to confirm these findings.

Abstract
Abstract
Background
Assessment of left ventricular (LV) diastolic function brings important prognostic information for patients with heart failure and could be evaluated by speckle tracking echocardiography (STE). Less known about its role in patients planned for surgical ventricular repair due to LV aneurysm.
Purpose
The aim of this study was to evaluate the prognostic role of STE parameters of LV diastolic function for prediction of all-cause mortality in patients after surgical ventricular repair.
Methods
We retrospectively evaluated data of 163 consecutive pts (mean age 62.3±11.5 years, 74.8% males) with anteroapical LV aneurysm who underwent surgical ventricular repair combined with coronary artery bypass surgery (71.8%) Prognostic role for prediction of all-cause mortality was assessed for various STE parameters, including left atrial strain (LAS) measured as peak reservoir strain and for the ratio of early to late global longitudinal strain rate (GLSRe/GLSRa).
Results
During a median follow-up of 4.7 years (IQR: 1.6–8.9 years) there were 65 deaths, 5 year survival rate was 73.8 (95% CI 67–79%). Baseline ejection fraction, end-diastolic and end-systolic volumes of LV did not differ between pts who died and survived at 5 year after the surgery, whereas LAS was significantly higher and GLSRe/GLSRa was significantly lower in survivors. Cox proportional hazard model adjusted to demographic and clinical variables demonstrated that LAS and GLSRe/GLSRa were independent predictors of all-cause death, with HR of 0.79 (95% CI 0.66–0.95, p=0.012) for each 5% increase of LAS and HR of 1.24 (95% CI 1.1–1.4, p=0.001) for each 0.5 increase of GLSRe/GLSRa. Moreover, GLSRe/GLSRa remained an independent predictor after additional adjustment for LV end-systolic volume, sphericity index and presence of mitral insufficiency of grade 2 and higher. A significant difference in median survival time was demonstrated according to the following cut-offs: LAS ≥16.7% (12.1 vs. 6.4 years, p=0.01), GLSRe/GLSRa ratio ≥2.3 (3.3 years vs. 10.2 years, p=0.0005) (Figure). The classification and regression tree analysis with the application of all two-dimensional, Doppler and various speckle-tracking echocardiographic parameters revealed that GLSRe/GLSRa and LAS were the most important echocardiographic variables for risk stratification for 5-year mortality.
Conclusion
This study demonstrates that STE parameters of LV diastolic function are important predictors of all-cause mortality after surgical ventricular repair due to anteroapical aneurysm of LV and could be used in the preoperative decision-making process.

Abstract
PurposeInformation literacy is defined as discrete abilities that a person requires to have in order to find, assess, use and share information. As information literacy skills play a prominent role in the students' academic achievement, students and in particular international students coming to continue their postgraduate studies in other countries may face problems in finding and using library services. The purpose of this paper is to explore and investigate the information literacy skills, challenges and needs of international and domestic students at the Finnish universities.Design/methodology/approachThis paper uses a mixed-methods design. Quantitative data were collected through an online survey (82 respondents) and qualitative data were collected through semi-structured interviews with 10 international and 10 domestic students.FindingsAcademic library services are used but in different ways. The findings indicate that international students have a relatively low level of information literacy skills compared to domestic students and faces various challenges, especially in the beginning of their studies.Research limitations/implicationsThe study was exploratory, and data were collected from limited number of Finnish universities and may not be representative of the underlying population.Practical implicationsAcademic libraries should provide effective courses on research methods and library services to the international students while keeping in mind the international students language and cultural barriers.Originality/valueThis is one of the first attempts in information literacy research that focusses on international and domestic students' information literacy skills at the higher education environment. As such, the results provided in this paper can help librarians and decision-makers at the higher education environments to plan better and become more efficient in delivering information services meeting students' information needs and expectations.

Abstract
Abstract
Introduction
Brain topography modulates age-related changes in the human sleep electroencephalogram, which are linked with differences in integrity of specific cortical areas and may reflect local changes in sleep homeostasis. In mice, there is conflicting evidence regarding the topography of age-related changes for NREM and REM sleep. To disambiguate this issue, we investigated in mice the topography of age-related spectral differences for REM and NREM sleep.
Methods
LFP electrodes were implanted in 5 cortical areas and in the hippocampus of 17 C57/BL6 mice (8 young and 9 old, mean age = 7.5 and 16 months). Mice LFPs were recorded for a week and states of vigilance were semi-automatically detected in light and dark periods (12h-12h). Spectral analysis was run on 4s windows. Values were averaged for each electrode and in each period of the light/dark cycle in REM/NREM sleep for slow delta (0.25-2Hz), delta (2-4Hz), theta (4-8Hz), sigma (10-16Hz) and ripples (150-200Hz). Mixed models were computed separately for REM and NREM in dark and light period, with age as group factor and electrode and frequency as repeated factors.
Results
Two-way interactions were found between age and frequency and between electrode and frequency, for NREM and REM in dark and light periods. Each frequency band, except ripples, showed a topographical signature in NREM and REM (e.g. higher power in anterior compared to posterior areas for delta band in NREM sleep). These relative patterns did not change in older mice, but global changes occurred on all electrodes: in older mice, delta power was globally higher in NREM and REM sleep whereas sigma power was lower in REM sleep.
Conclusion
Age-related changes in spectral power of sleeping mice do not vary according to brain topography as in humans. Sleep deprivation studies are needed to investigate whether age is associated with global changes in sleep homeostasis in mice.

Abstract
Despite the favorable association of components of "dietary approaches to stop hypertension (DASH)" diet and breast cancer (BC), limited data are available linking the whole DASH diet to BC. The aim of the present study was to examine the association between adherence to DASH eating plan and odds of BC in Iranian women. This population-based case-control study was conducted among women aged ≥30 years, who were residing in Isfahan, Iran. Cases were 350 patients with newly diagnosed stage I-IV breast cancer, for whom in-situ or invasive status of BC was confirmed by physical examination and mammography. Controls were 700 age-matched apparently healthy individuals who were randomly selected from general population. Dietary data were collected using a validated 106-item Willett-format semi-quantitative dish-based food frequency questionnaire. To investigate participants' adherence to DASH diet, we created DASH scores based on foods and nutrients emphasized or minimized in the DASH diet. After controlling for potential confounders, individuals in the highest quartile of the DASH diet score had 85% lower odds of breast cancer than women in the bottom quartile (OR: 0.15; 95% CIs: 0.09-0.24). Stratified analysis by menopausal status revealed such association in postmenopausal women (OR: 0.11; 95% CI: 0.06-0.19), but not in premenopausal women (OR: 0.60; 95% CI: 0.14-2.59). In addition, when stratified by BMI status, we found statistically significant inverse association between adherence to the DASH eating pattern and odds of breast cancer among normal-weight (OR for comparing extreme quartiles: 0.13; 95% CI: 0.07-0.24; P-trend < 0.001) and obese women (0.13; 0.05-0.34; P-trend < 0.001). In conclusion, our findings indicated an inverse association between adherence to the DASH eating plan and odds of breast cancer among Iranian women. Further, prospective studies are required to confirm our findings.

Abstract
Abstract
Background
Surgical ventricular repair (SVR) in patients with ischemic cardiomyopathy is aimed to reshape left ventricle (LV) and reduce its volume in order to improve prognosis and quality of life. There are controversies regarding benefit of SVR, especially in patients with severely enlarged LV.
Purpose
Our purpose was to investigate prognostic value of LV longitudinal strain for survival and for the improvement of LV function after SVR in patients with anteroapical LV aneurysm.
Methods
218 pts (2005-2018, mean age 63.6 ± 11.2y, 73.9% males) with anteroapical LV aneurysm due to myocardial infarction underwent SVR combined with coronary bypass grafting (77.5%), mitral valve repair (18.3%) and LV thrombectomy (22.0%). Preoperative strain analysis was done retrospectively for 146 patients. Prognostic value of strain was tested in pts according to the LV end systolic volume index (LVESVI) with the cut-off value of 60ml/m². In 17 pts 1-year follow-up with strain quantification was done.
Results
During a median follow-up of 3.9 years (IQR: 1.0-6.8 years) there were 68 deaths and 1 patient was lost to follow-up. 30-days survival rate was 93.5% (95%CI: 90.3; 96.9%), 5 year survival – 72.5% (95%CI: 66.0-79.6%). Pts who died were significantly older, with higher proportion of diabetes (DM), peripheral artery disease, renal failure (RF) and atrial fibrillation (AF). Baseline ejection fraction (EF) and global longitudinal strain (GLS) did not differ significantly. Whereas basal longitudinal strain (BLS) was higher (more negative) in pts who survived (-11.4 ± 3% vs. -10.1 ± 4%, p = 0.027). Risk stratification by tertiles revealed that BLS was a significant predictor of survival. The risk of dying was 3 times higher for pts in the lowest tertile compared to those in the highest tertile (HR: 2.94, 95%CI:1.37-6.25, p = 0.013). When adjusted to age, AF, DM, RF, and previous heart surgery, BLS was an independent predictor of death (HR = 1.14, 95%CI:1.03;1.26, p = 0.032). At 1-year follow-up (12.7 ± 5.1 months) there was significant decrease of LV end-diastolic and end-systolic volume indices, from 102.8 ± 24.1 ml/m² to 77.9 ± 24 ml/m² (p < 0.001) and from 67 ± 23.2 ml/m² to 44.3 ± 7.6 ml/m² (p < 0.001), correspondingly, and increase of EF from 36.3 ± 9.4% to 44.4 ± 7.6% (p = 0.001). The mean systolic GLS improved from -6.6 ± 2.6% to -8.7 ± 3.2%, p = 0.008. Among 81 segments with baseline hypokinesia, 44 segments (54.3%) recovered their contractility, 36 segments (44.4%) remained hypokinetic and 1 segment deteriorated to akinesia. Mean systolic strain of segments which showed recovery was -6.6 ± 4.0% compared to -3.8 ± 4.5% with no improvement (p = 0.005). Cut-off value of systolic strain for prediction of recovery was -5.4 % (AUC = 0.69, p = 0.004; PPV = 0.73, NPV = 0.61).
Conclusion
Our study demonstrates that BLS is an independent predictor of survival after SVR in patients with LV anteroapical aneurysm. Furthermore, higher systolic strain predicts recovery of LV regional function at 1-year after SVR.

Abstract
BACKGROUND To construct a dietary guideline for patients with irritable bowel syndrome (IBS), data about foods these people exclude from their diet to improve their symptoms are necessary. This study was designed to assess the prevalence of food exclusions as well as the reasons for such exclusions in a large group of IBS patients. METHODS In this cross-sectional study, data on 3846 Iranian adults, 828 of whom were patients with IBS, working in 50 different health centers were examined. A 106-item self-administered Dish-based Semi-quantitative Food Frequency Questionnaire (DSFFQ) which was designed and validated specifically for Iranian adults was used for assessing dietary intake. IBS was assessed using a modified Persian version of the Rome III questionnaire. RESULTS The whole prevalence of IBS was 21.5% (n = 828) in the total population (23.9% in women and 18.6% in men). Mean age of patients with IBS was 36.26 ± 7.91 years and for subjects without IBS, it was 36.52 ± 8.12 years. IBS patients had a greater probability to avoid consumption of ketchup (90% vs 33%, P = 0.005), Dough (100% vs 1%, P = 0.003), Gaz (50% vs. 1%, P = 0.035), grapes (33% vs. 7%, P = 0.034), fresh berries (56% vs. 14%, P = 0.036) and butter (100% vs. 60%, P = 0.02) due to gastrointestinal (GI) symptoms compared with healthy individuals. Although, the exclusion of plum (1% vs. 26%, P = 0.006), pickles (39% vs. 67%, P = 0.004), lemon juice (21% vs 35%, P = 0.027), egg (5% vs. 25%, P = 0.011), fresh fig (19% vs. 44%, P = 0.038) and cake (25% vs. 100%, P = 0.028) due to GI symptoms in IBS patients were lower than non-IBS participants. CONCLUSION The present study showed that IBS patients were more likely to avoid consumption of ketchup, Dough, Gaz, grapes, fresh berries and butter due to GI symptoms compared with healthy individuals. Further studies are required to confirm these findings.

Abstract
PURPOSE To understand the typical presentation, risk factors, location and size, treatment, neurological recovery and survival of spontaneous spinal epidural haematomas (SSEH) in children. METHODS A systematic review of the English literature from 1 January 1960 to 1 March 2018 was performed on children aged 18 years and younger. Individual patient data were extracted and collated. Outcome measures were mode of presentation, risk factors, initial neurological findings, initial presumed diagnosis, diagnostic investigations, site and size of the SSEH, treatment, neurological recovery and survival. RESULTS Thirty-one publications and 36 patients were reviewed. All age groups were affected. 83% of patients did not have a known risk factor. Back pain was reported in 61% and neurological dysfunction in 97% of patients, although not all articles defined these parameters. Initially 28% of patients were suspected of having an alternative diagnosis. All patients had an MRI and/or CT scan confirming the diagnosis. The cervical-thoracic region was most commonly affected, and the average haematoma size extended across 6.3 vertebral levels. Surgical decompression was performed in 72% of patients. Neurological function improved in 83% of patients. Two patients died as a consequence of their SSEH. CONCLUSIONS SSEHs affect all paediatric age groups and typically present with neurological dysfunction and/or back pain. The initial diagnosis is incorrect in up to 28% of cases, but cross-sectional spinal imaging is diagnostic. Most SSEHs are located in the cervico-thoracic region and affect multiple spinal levels. The treatment depends on whether the patient has a bleeding disorder and their neurological status. These slides can be retrieved under Electronic Supplementary Material.

Abstract
BACKGROUND Earlier studies on the obesity-IBS association have mostly been reported from Western nations, and limited data are available in this regard from developing countries. This study was performed to examine the association of general and abdominal obesity with Irritable bowel syndrome (IBS) in a Middle Eastern population. METHODS In this cross-sectional study, 4763 Iranian adults participated. Data on self-reported anthropometric measurements were collected, and BMI was calculated. Overweight and obesity were defined as 25 ≤ BMI < 30 and BMI ≥ 30 kg/m2 , respectively. Also, we used WC measurements to define the three categories of normal (<94 cm in men <80 cm in women), abdominal overweight (94 ≤ WC < 102 in men and 80 ≤ WC < 88 in women), and abdominal obesity (WC ≥ 102 cm in men and WC ≥ 88 cm in women). Assessment of different GI symptoms including those related to IBS was done using a validated Persian version of the Rome III questionnaire. IBS was defined as the presence of recurrent abdominal pain or discomfort at least sometimes in the last 3 months associated with 2 or more of the following features: improvement with defecation, pain onset associated with a change in frequency of stool, and pain onset associated with a change in form (appearance) of stool. KEY RESULTS Irritable bowel syndrome was more prevalent among individuals with abdominal obesity compared with normal subjects (23.8% vs 19%). Neither in crude nor in adjusted models, we found any significant association between overweight and obesity and IBS [for overweight: OR: 0.95, 95% CI: 0.66-1.36 and for obesity: OR: 1.06, 95% CI: 0.85-1.31]. We observed a significant positive association between abdominally overweight and IBS in crude model (OR: 1.31, 95% CI: 1.09-1.60); however, this association became non-significant after adjustment for potential confounders (OR: 1.09, 95% CI: 0.82-1.44). Across BMI categories, neither in crude nor in adjusted models, we did not find any significant association between overweight (OR: 0.89, 95% CI: 0.62-1.27), obesity (OR: 1.05, 95% CI: 0.58-1.87), and abdominal pain severity. Abdominal overweight (OR: 0.96, 95% CI: 0.65-1.40) and obesity (OR: 1.61, 95% CI: 0.67-1.63) were not associated with abdominal pain severity. CONCLUSIONS AND INFERENCES It is concluded that general or abdominal obesity was not associated with odds of IBS. Future longitudinal studies are needed to clarify the association between obesity and IBS.

Abstract
Abstract
Background: Biological factors, such as HER2 signaling activity, may be important to measure in addition to expression and amplification of HER2 when identifying patients eligible for HER2 therapies. The CELx HER2 Signaling Function (CELx HSF) Test measures HER2 signaling activity in live tumor cells using a label-free impedance biosensor to identify HER2-negative breast cancer patients likely to be responsive to treatment with anti-HER2 therapies. Previous studies quantified HER2-driven signaling activity in a training set (N=34) of primary tissue samples from HER2-negative breast cancer patients and found 21% of the samples had abnormal HER2 signaling. Other studies confirmed that anti-HER2 therapies, such as trastuzumab, pertuzumab, afatinib, and neratinib, are as effective in inhibiting HER2-driven signaling activity in HER2- tumor cells as they are in HER2+ tumor cells. This study set out to confirm the prevalence of abnormal HER2 signaling amongst HER2-negative breast cancer patients in a larger sample (N=114) and to characterize the sensitivity and specificity of the CELx HSF Test.
Methods: A validation set of de-identified fresh breast tumor specimens were obtained from 114 HER2- breast cancer patients. Real time live cell response to specific HER2 agonists (NRG1b or EGF) with or without an antagonist (HER2 dimerization inhibitor) was measured using an impedance biosensor. From these responses, the net amount of HER2 participation in HER2 signaling initiated by the HER2 agonists was quantified. Samples with HER2 signaling activity levels above a previously determined cut-off value were identified as abnormal.
Results: Of the HER2- breast tumor cell samples tested, 27 of 114 patients (23.7%; 95% CI=17%-32%) had abnormal HER2 signaling activity. Little or no correlation was found between a patient's HER2 signaling activity and their estrogen receptor status or tumor grade. To compare the results obtained from the training set of 34 patients and the current set of 114 patients, the Kolmogorov-Smirnov two-sample test was applied (D=0.17, P-value 0.45) and found no significant difference between the training and validation sets. A normal mixture model was fitted to the new 114 patient data set and found that HER2- breast cancer patients fall into three distinct groups (abnormal, normal, low). Patients falling into the abnormal group had mean HER2 signaling scores 4.5 standard deviations above the mean score of the normal group. A ROC curve constructed with this data projects that both the sensitivity and specificity of the CELx HSF Test would be greater than 90%.
Conclusions: These results confirm that a clinically relevant proportion of HER2- breast cancer patients, approximately 20%, have tumors with abnormal HER2-signaling activity and may benefit from HER2 therapy. With high specificity and sensitivity, the CELx HSF test may be suitable as a companion diagnostic to identify new patients eligible to receive HER2 therapies. An interventional trial to evaluate the efficacy of trastuzumab and pertuzumab in HER2- patients selected with the CELx HSF test is underway.

Abstract
Abstract
Background: Advanced breast cancer (BC) and endometrial cancer (EC) have limited treatment options with no treatments improving survival. ONC201 is the founding member of a novel class of anticancer drugs called impiridones. The drug is orally bioavailable and crosses the blood brain barrier. Preclinical studies have demonstrated that ONC201 selectively kills various cancer cells, including all subtypes of BC and EC, while having little effect on normal cells. An on-going Phase 1 study of ONC201 has demonstrated clinical benefit in some solid tumors, including EC and glioblastomas.
Trial Design: Phase 2 single arm study of ONC201 with 3 cohorts: Cohort 1, female and male hormone receptor positive breast cancer (HR+BC); Cohort 2, female and male triple negative breast cancer (TNBC); and Cohort 3, EC. All patients will receive ONC201 at the recommended Phase 2 dose of 625mg by mouth q7 days (1 cycle = 28 days). Patients will undergo a baseline biopsy as well as a biopsy after 5 doses of ONC201 (C2D2). Patients will be evaluated for response every two cycles (8 weeks) by RECIST 1.1.
Eligibility Criteria: Measurable disease with >1 biopsiable lesion, willing to undergo biopsies. Cohort 1 (HR+BC) requires prior treatment with >2 lines of hormonal treatment. No prior treatment required for the other cohorts. Patients must have ECOG 0-1 and adequate organ function. Patients with asymptomatic or brain metastases treated > 4 weeks from study entry are eligible. Exclusion criteria include: symptomatic CNS metastases, radiotherapy ≤ 4 weeks from study entry, HIV, Hepatitis B or Hepatitis C.
Specific Aims: Primary objectives for this study are progression free survival (PFS) at 8 months for Cohort 1 (HR+BC) and overall response rate (ORR) for Cohorts 2 and 3 (TNBC and EC). Secondary objectives include safety, clinical benefit rate (CBR = partial response + complete response + stable disease), and overall survival.
Statistical Methods: This study has been designed to pause prior to full accrual to allow for evaluation of futility prior to proceeding to full accrual. In Cohort 1, if >1 of 5 patients is progression-free at 8 months, then we will recruit up to 24 patients. In Cohort 2, if >2 of 10 patients has clinical benefit then we will recruit up to 29 patients. For Cohort 3, if 1 of 13 patients has clinical benefit, then we will recruit up to 25 patients. Additional evaluations of tumor or blood samples performed will be done in an exploratory fashion, with results presented without any formal adjustment for multiple comparisons.
Target Accrual: 24 patients with HR+BC, 29 patients with TNBC, and 25 patients with EC.This trial will open Summer 2017 at the National Institutes of Health (Bethesda, MD).

Abstract
PURPOSE Breast tumors from young women under the age of 40 account for approximately 7% of cases and have a poor prognosis independent of established prognostic factors. We evaluated the patient population served by the Military Health System, where a disproportionate number of breast cancer cases in young women are seen and treated in a single universal coverage healthcare system. METHODS The Military Health System Repository and the DoD Central Registration databases were used to identify female breast cancer patients diagnosed or treated at military treatment facilities from 1998 to 2007. RESULTS 10,066 women were diagnosed with invasive breast cancer at DoD facilities from 1998 to 2007, of which 11.3% (1139), 23.4% (2355) and 65.2% (6572) were < 40, 40-49 and > 50 years old (yo), respectively, at diagnosis. 53% in the < 40 yo cohort were white, 25% were African American (AA) and 8% were Hispanic, with 14% undisclosed. Breast cancer in women diagnosed < 40 yo was more high grade (p < 0.0001), Stage II (p < 0.0001) and ER negative (p < 0.0001). There was a higher rate of bilateral mastectomies among the women < 40 compared to those 40-49 and > 50 (18.4% vs. 9.1% and 5.0%, respectively). Independent of disease stage, chemotherapy was given more frequently to < 40 yo (90.43%) and 40-49 yo (81.44%) than ≥ 50 yo (53.71%). The 10-year overall survival of younger women was similar to the ≥ 50 yo cohort. Outcomes in the African American and Hispanic subpopulations were comparable to the overall cohort. CONCLUSION Younger women had a similar overall survival rate to older women despite receiving more aggressive treatment.

Abstract
BACKGROUND A clear picture of interaction of Th1/Th2 cytokines in pathogenesis of chronic spontaneous urticaria (CSU), remains elusive. Impaired IFN-γ production and decreased levels of IL-2 have been reported. The aim of this study was to evaluate the association of Th1 cytokines; IL-2, IL-12 and IFN-γ polymorphisms with CSU. METHODS 90 patients with CSU and 140 age-sex matched subjects were included in this study. DNA samples were evaluated through PCR-SSP assay in order to detect single nucleotide polymorphisms of IL-12 (A/C -1188) or (rs3212227), IFN-γ (A/T UTR5644) or (rs2069717) and IL-2 (G/T -330 and G/T +166) or (rs2069762 and rs2069763). RESULTS G allele at -330 at promoter region of IL-2 gene was overrepresented in CSU. Heterozygotes (GT) at this locus and heterozygotes at +166 of IL-2 gene (GT) were more prevalent in CSU group. Additionally, the haplotype GT for loci -330 and +166 of IL-2 gene was powerfully associated with CSU (OR (95%CI)=57.29 (8.43-112.7)). CONCLUSIONS SNP at position -330 and +166 of IL-2 gene are differently expressed in CSU. The haplotype GT of IL-2 at -330 and +166 might confer vulnerability to a number of immunological disorders in Iranian region.

Abstract
Abstract
Background: Clinical trials have indicated a weak correlation between HER2 expression levels and HER2 targeted therapy benefit. Other biological factors, such as HER2 signaling activity, may be important to measure, in addition to expression and amplification of HER2, when identifying patients eligible for HER2 therapies. To measure the HER2-driven signaling activity of a patient's tumor cells, a new assay using an impedance biosensor, the CELx HER2 Signaling Profile (CELx HSP) Test, was developed. This study set out to provide an initial assessment of the CELx HSP Test, specifically to: 1) quantify HER2-driven signaling activity (HER2S) in cell lines and primary epithelial cells; 2) assess the correlation between HER2 expression levels and HER2 signaling activity; 3) define a preliminary cut-point between normal and abnormal HER2 signaling; and 4) estimate the proportion of HER2- primary breast cancer tumors with abnormal HER2 signaling.
Methods: A training set of de-identified fresh breast tissue specimens was obtained from 50 patients, 34 with HER2- breast cancer (IHC 0 or 1+) and 16 healthy patients. Cell samples were comprised of epithelial cells extracted and cultured from each specimen. Reference human breast cancer cell lines (9 HER2+, 10 HER2-) were also tested, including two cell lines used as controls in IHC HER2 tests. Real time live cell response to specific HER2 agonists (NRG1b or EGF) and with or without an antagonist (pertuzumab, an FDA-approved HER2 dimerization inhibitor) was measured and quantified using an xCELLigence RTCA impedance biosensor (ACEA Biosciences, San Diego, CA). From these responses, the net amount of HER2 participation in HER2 signaling initiated by the HER2 agonists (“HER2S”) was determined. Fluorescence cytometry was used to measure HER2 expression levels of each cell sample.
Results: Of the HER2– breast tumor cell samples tested, 7 of 34 patients (20.5%; 95% CI=10%-37%) had net HER2 signaling activity that was greater than the median HER2S of the HER2+ cell lines. There was no categorical correlation between HER2 IHC status (+ or -) and HER2 signaling activity (abnormal or normal) (Pearson's Chi-Square = 3.68; Phi Max = -0.78, Contingency Coefficient 0.28). The median HER2S, or net HER2 signaling activity, was comparable for the HER2- tumor, HER2- cell line, and the healthy patient samples (Md = 100, 117, 77, respectively). The median HER2S in HER2+ cell lines (Md = 248) is approximately 2.5-3.0 fold greater than the median of the other groups. A HER2S above 250 was considered abnormal or test positive, and was defined as the cut-point. The HER2S for the two IHC HER2 test control cell lines, SKBR3 for HER2+ and MDA-MB231 for HER2-, was 544 and 0.
Conclusions: These findings provide strong evidence that measurement of HER2 signaling activity may provide clinically relevant information, particularly for HER2- breast cancer patients. These results suggest a new group of HER2- breast cancer patients with abnormal HER2-driven signaling may benefit from anti-HER2 therapy. Additional studies are underway to confirm these findings and to analytically validate the CELx HSP test.

Abstract
Abstract
Background: A new functional cellular analysis platform, the CELx HER2 Signaling Profile (CELx HSP) Test, uses a label-free impedance biosensor to measure HER2 signaling activity in live tumor cells. A recently completed study quantified HER2-driven signaling activity in epithelial cell samples extracted and cultured from fresh breast tissue specimens obtained from 34 patients with HER2-negative breast cancer (DAKO 0 or 1+). Of the cell samples tested, 7 of 34 HER2-negative breast tumor patients (20.5%; 95% CI=10%-37%) were found to have abnormal HER2 signaling activity (HER2S+). The current study set out to: 1) evaluate the primary cells with abnormal HER2-driven signaling with four HER2 signal inhibitors - pertuzumab, lapatinib, neratinib, afatinib; and 2) evaluate the same four HER2 signal inhibitors with 9 HER2-positive cell lines. The objective was to quantify the percentage of HER2-driven signaling activity each drug could inhibit ex vivo in the primary cell samples and cell lines. Comparing the results between the HER2-negative primary cells and the HER2-positive cell lines was also of interest. The anti-HER2 drug, trastuzumab, was not studied because its primary mechanism of action does not appear to be direct mediation of HER2-driven signaling.
Methods: Epithelial cells from the 7 HER2-negative tumor specimens with abnormal HER2-driven signaling (HER2S+) and the 9 HER2-positive cell lines were obtained. Real time live cell response to NRG1, a specific HER2/HER3 agonist, with or without a HER2 targeted drug (pertuzumab, lapatinib, neratinib, afatinib) was measured and quantified using an xCELLigence RTCA impedance biosensor (ACEA Biosciences, San Diego, CA). Clinically relevant concentrations of the HER2 drugs were used. From these responses, the percentage inhibition of the HER2-driven signaling initiated by NRG1 by the HER2 drugs was determined.
Results: Each of the HER2 drugs inhibited an average of at least 69% of the HER2-driven signaling activated by NRG1 stimulation in the HER2-negative primary cell samples; the highest level of inhibition was found with the two irreversible covalent dual RTKi's, afatinib and neratinib. All of the HER2 drugs inhibited a greater percentage of HER2-driven signaling in the HER2-negative primary tumor cells than in the HER2-positive cell lines.

Conclusions: These findings provide strong evidence that HER2 signal inhibitors are effective in blocking abnormal levels of HER2-driven signaling (HER2S+) ex vivo in live primary cells from breast cancer patients with normal expression levels of HER2. These results suggest a new group of breast cancer patients, HER2-negative with abnormal HER2 signaling (HER2-/HER2S+), may benefit from the addition of HER2 signal inhibitors to current combination therapeutic regimens. Additional studies to confirm these findings are underway.

Abstract
Abstract
Background: Women under the age of 40 account for approximately 7% percent of breast cancer patients. Breast tumors from young women are often ER-negative, occur in African-American patients, and have other indicators of high risk: yet, multivariate analyses demonstrated that young age is an independent predictor of poor outcome. Due to the unique nature of the patient population served by DOD, a disproportionate number of breast cancer cases in young women are seen. We compare the characteristics, treatment, and outcomes of young patients diagnosed with breast cancer with those of older patients.
Methods: The databases of the Military Health System Repository and the DOD Central Registration were used to identify female breast cancer patients treated at DOD facilities between 1998 and 2007. Information on demographics, breast cancer stage at diagnosis, definitive surgical treatments, systemic treatment, recurrence rate and overall survival was analyzed by age groups at the time of diagnosis (less than 40 years old, 40 to 49 years, and 50 years or older) using X2 testing with significance defined as p< 0.05.
Results: We identified 10,066 women who were diagnosed with invasive breast cancer at DOD facilities between 1998 and 2007, of which 11.3% (1139) were less than 40 years old at diagnosis. 53% of this young cohort were white, 25% were African-American and 8% were Hispanic (14% undisclosed). The percentage of breast cancer among African-American women in the young cohort was higher than in the older cohorts (19.3% in 40-49yo and 10.6% in ≥50yo). High-grade tumors were significantly more frequent in the younger cohort when compared to the older group (49.5% vs 34.7% and 25.2%, p<0.001). <40yo most commonly presented with Stage II disease (45.3%) at diagnosis, while older groups were mostly diagnosed with Stage I disease (41.6% and 52.4%). The most common subtype of breast cancer across ages was ER+ disease, however, <40yo group had proportionally less ER+ (49% vs 61% and 67.3%, P<0.001). There was a higher rate of bilateral mastectomies among the young women (18.4% vs 9.1% and 5.0%, p<0.0001). Independently of the stage of disease, chemotherapy was given significantly more frequently to <40y (90.43%) and 40-49yo (81.44%) than ≥50yo (53.71%). The 10-year overall survival of younger women was similar to the ≥50yo cohort, despite intensive treatment.
Discussion: This study is one of the largest retrospective studies of women under 40 years old with breast cancer. Younger women with invasive breast cancer had more aggressive tumors presenting at higher stages. In this group with good access to healthcare, younger women still had a similar overall survival rate to older women despite receiving more aggressive treatment and potentially having fewer comorbidities than the older group.

Abstract
UNLABELLED We assessed the impact of weight loss strategies including calorie restriction and exercise training on BMD in adults using a systematic review of randomized controlled trials. Weight reduction results in reduced BMD at the hip, but has less effect on the spine. Both calorie restriction and a combination of calorie restriction and exercise result in a decrease in hip bone density, whereas weight loss response to exercise training without dietary restriction leads to increased hip BMD. INTRODUCTION Findings are not consistent on the effect of weight loss on bone mineral density (BMD). We conducted a systematic review on the randomized controlled trials to assess the effect of weight loss strategies, including calorie restriction and exercise programs on BMD in adults. METHODS A structured and comprehensive search of MEDLINE and EMBASE databases was undertaken up to March 2016. Study-specific mean differences (MD) were pooled using a random-effects model. Subgroup analysis and meta-regression were used to find possible sources of between-study heterogeneity. RESULTS Thirty-two randomized controlled trials met predetermined inclusion criteria. The meta-analysis revealed no significant difference on total BMD (MD 0.007, 95 % CI -0.020-0.034, p = 0.608). In contrast, the pooled data of studies showed a significant effect of weight loss on hip BMD (MD -0.008, 95 % CI -0.09 to -0.006 g/cm(2), p < 0.001) and also lumbar spine BMD (MD -0.018 g/cm(2), 95 % CI -0.019 to -0.017, p < 0.001). BMD in the hip site decreased after more than 4 months, especially in those who were obese. Moreover, calorie restriction interventions longer than 13 months showed a significant decreased in lumbar spine BMD. CONCLUSION Weight loss led to significant decreases at the hip and lumbar spine BMD but not at the total. Weight loss response following calorie restriction resulted in a decrease in hip and lumbar spine bone density especially more than 1 year; whereas an exercise-induced weight loss did not.

Abstract
PURPOSE Juvenile systemic lupus erythematosus (JSLE) is a severe and chronic autoimmune disease of unknown origin. Inflammatory cytokines can play a pivotal role in the pathogenesis of JSLE, while their secretion is under genetic control. The current investigation was performed to analyse the associations of particular single nucleotide polymorphisms (SNPs) of interleukin-2 (IL-2) and interferon-gamma (IFN-γ) genes in a case control study. MATERIALS AND METHODS The allele, genotype and haplotype frequencies of the polymorphic IL-2 (G/T at -330, rs2069762, and G/T at +166, rs2069763) and IFN-γ (A/T at +874, rs2430561) genes were estimated in 59 patients with JSLE by contrast with 140 healthy controls using polymerase chain reaction with sequence-specific primers method. RESULTS Results of the analysed data revealed a negative allelic association for JSLE in IL-2 -330/T (P=0.02), as well as a positive allelic association for IL-2 -330/G (P=0.02). IL-2 GG genotype (-330) in the patient group was also significantly overrepresented (P<0.001), while IL-2 GT genotype (-330) was notably decreased in the patients with JSLE (P<0.001). Additionally, the frequency of IL-2 (-330, +166) GT haplotype was significantly higher in the patient group (P<0.001). CONCLUSION IL-2 cytokine gene polymorphisms could affect individual susceptibility to JSLE and can take on the role of possible genetic markers for vulnerability to JSLE.

Abstract
BACKGROUND Filaggrin (FLG), which is formed from profilaggrin protein during epidermal terminal differentiation, is a prerequisite to squame biogenesis and thus for perfect formation of the skin barrier. Yet, the relationship between genetic polymorphisms of FLG and chronic idiopathic urticaria (CIU) has not been investigated. METHODS The study population consisted of 93 CIU patients and 93 healthy control subjects without a history of allergic, autoimmune or any other systemic disease. Five single nucleotide polymorphisms (SNPs) of FLG were investigated: rs2485518, rs3126065, rs2786680, rs3814300, and rs3814299. RESULTS For all the investigated polymorphisms, 100% of both CIU patients and control subjects exhibited one given allele and consequently one given genotype as following: A/A genotype for two SNPs, rs3126065 and rs2786680, C/C genotype for two SNPs, rs2485518 and rs3814300, and G/G genotype for one SNP rs3814299 of FLG, and hence no association was found between either allele frequencies or genotype distributions of FLG SNPs and CIU in an Iranian population. CONCLUSIONS The present study examined the possible relationship between SNPs of FLG and CIU for the first time, and demonstrated that none of five investigated SNPs (rs2485518, rs3126065, rs2786680, rs3814300, and rs3814299) are correlated with CIU in an Iranian population. Further investigations are required to address whether ethnicity/race impacts on relationship between SNPs of FLG and CIU.

Abstract
Lipoprotein-associated phospholipase A2 (Lp-PLA2) is produced by inflammatory cells, bound to LDL and other lipoproteins, and hydrolyzes oxidized phospholipids in LDL. Type 2 diabetes is the most common form of diabetes some investigations show the association of lipoprotein-associated phospholipase A2 mass and activity with the incidence of cardiovascular disease (CVD) in populations with high prevalences of insulin resistance and diabetes. This study is a cross-sectional descriptive and analytic study on 80 individuals with diabetes referring to the Tehran Diabetes Association. Patients divided into two groups (well-controlled and poorly controlled) based on their HbA1C. Personal information, anthropometric assessments (including height, weight, waist circumference and hip circumference) and semi-quantitative 147 items FFQ was used and vein blood samples were taken. After plasma separation, blood sample used for FBS, HbA1c and LP-PLA2 measurement. The independent sample T test was used for comparing means. Data analyses showed a significant difference between weight and WHR (waist to hip ratio) means in two studied groups, also there was a statistically significant difference in food intake (Energy, carbohydrate, protein, micronutrients percent and some of the micronutrients). FBS, HbA1C and LP-PLA2 means showed statistically significant difference (P<0/001) between two groups. This study showed LP-PLA2 is elevated in poorly-controlled patients compared to well-controlled diabetic patients, which may suggest some nutritional factors contributing to the regulation of this enzyme.

Abstract
Soy isoflavones (SIF) are present in the systemic circulation as conjugated forms of which the estrogenic potency is not yet clear. The present study provides evidence that the major SIF glucuronide metabolites in blood, genistein-7-O-glucuronide (GG) and daidzein-7-O-glucuronide (DG), only become estrogenic after deconjugation. The estrogenic potencies of genistein (Ge), daidzein (Da), GG and DG were determined using stably transfected U2OS-ERα, U2OS-ERβ reporter gene cells and proliferation was tested in T47D-ERβ cells mimicking the ERα/ERβ ratio of healthy breast cells and inT47D breast cancer cells. In all assays applied, the estrogenic potency of the aglycones was significantly higher than that of their corresponding glucuronides. UPLC analysis revealed that in U2OS and T47D cells, 0.2-1.6% of the glucuronides were deconjugated to their corresponding aglycones. The resulting aglycone concentrations can account for the estrogenicity observed upon glucuronide exposure. Interestingly, under similar experimental conditions, rat breast tissue S9 fraction was about 30 times more potent in deconjugating these glucuronides than human breast tissue S9 fraction. Our study confirms that SIF glucuronides are not estrogenic as such, and that the small % of deconjugation in the cell is enough to explain the slight bioactivity observed for the SIF-glucuronides. Species differences in deconjugation capacity should be taken into account when basing risk-benefit assessment of these SIF for the human population on animal data.

Abstract
BACKGROUND This study was performed to evaluate association of gene polymorphisms among proinflammatory cytokines and susceptibility to chronic idiopathic urticaria (CIU). METHODS Ninety patients with prolonged urticaria more than 6 weeks were included as case group. Single nucleotide polymorphisms (SNPs) of IL-6 (G/C -174, G/A nt565) and TNF-α (G/A -308, G/A -238) were evaluated, using polymerase chain reaction (PCR); and the results were compared to the control group. RESULTS G allele was significantly higher in the patients at locus of -238 of promoter of TNF-α gene (p<0.001). Frequency of following genotypes were significantly lower in patients with CIU, compared to controls: AG at -308 and GA at -238 of TNF-α gene (p<0.05 and p<0.001, respectively), CG at -174 and GG at +565 of IL-6 gene (p<0.05). Additionally, following genotypes were more common among patients with CIU: GG at -308 and -238 of TNF-α gene (p<0.05 and p<0.001, respectively), GG at -174 and GA at +565 of IL-6 gene (p<0.05). CONCLUSIONS Pro-inflammatory cytokine gene polymorphisms can affect susceptibility to CIU. TNF-α promoter polymorphisms as well as IL-6 gene polymorphisms are associated with CIU.

Abstract
BACKGROUND Primary antibody deficiencies (PADs) are a heterogeneous group of disorders, characterised by increased susceptibility to recurrent bacterial infections. Common variable immunodeficiency (CVID) is the most important PAD from the clinical point of view and selective IgA deficiency (IgAD) is the most common PAD. However, the underlying gene defect in both is still unknown. As a recent study in Europe showed an association between a single nucleotide polymorphism (SNP) of AICDA gene with PADs, this study was performed to evaluate such an association in Iranian patients. METHODS Fifty-eight patients with PAD, including 39 CVID and 19 IgAD, as well as 34 healthy volunteers, were enrolled in this study. Genotyping was done in all groups for an intronic SNP in AICDA (rs2580874), using real-time PCR genotyping assay. RESULTS The less frequent genotype of AICDA in IgAD patients was AA, seen in 10.5% of the patients, which was much lower than the 30.8% in CVID patients and 38.2% in the controls. However, these differences were not significant. Indeed the GG genotype in the patients with PADs was seen in 20.7%, compared to 8.8% in the controls without any significant difference. CONCLUSIONS There was no significant association between the previously reported genetic variant of AICDA gene and the development of CVID or IgAD, but further multi-center studies are also needed.
