RESUMO

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.

RESUMO

Objectives: Although some components of MIND diet have been shown to have favorable association with glioma, no information exist about the potential link between adherence to the whole MIND diet and risk of glioma. This study was conducted to examine the association between adherence to MIND diet and risk of glioma in a group of Iranian adults.Methods: In this hospital-based case-control study, 128 newly diagnosed glioma cases and 256 age- and sex-matched controls were included. Dietary intakes of study participants were assessed using a validated 126-item semi-quantitative FFQ. The MIND diet score was computed based on participants' dietary intakes obtained from FFQ. Conditional logistic regression models were used to examine the association between the MIND diet score and glioma.Results: After controlling for age, sex and energy intake, individuals with the greatest adherence to the MIND diet were less likely to have glioma compared with those with the lowest adherence; such that those in the top tertile were 47% less likely to have glioma than those in the bottom tertile (OR: 0.53; 95% CI: 0.30-0.94). Further adjustment for other potential confounders strengthened the association (OR for the highest tertile vs. the lowest: OR: 0.37; 95% CI: 0.18-0.79). Additional controlling for BMI did not influence the association significantly (OR: 0.39; 95% CI: 0.18-0.84).Discussion: In conclusion, we found that adherence to the MIND diet might be inversely associated with odds of glioma in this case-control study. Further studies are required to confirm these findings.

RESUMO

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.

RESUMO

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.

RESUMO

LESSONS LEARNED: Monotherapy with prexasertib demonstrated modest activity in BRCA wild-type, recurrent triple-negative breast cancer, highlighting the unmet need for combination treatment strategies. Neutropenia, anemia, and thrombocytopenia are common with the use of prexasertib but are manageable with supportive care measures. Prophylactic use of granulocyte colony stimulating factor should be considered to avoid dose reductions or treatment delays. Pharmacodynamic studies showed prexasertib treatment induced DNA damage in peripheral immune cells. BACKGROUND: Cell cycle checkpoint kinase 1 (CHK1) is a major G2/M cell cycle regulator in tumors with p53 dysfunction, such as triple-negative breast cancer (TNBC). We hypothesized the second-generation CHK1 inhibitor, prexasertib, would yield clinical activity in sporadic TNBC. METHODS: This single arm, phase II trial evaluated prexasertib at 105 mg/m2 IV every 2 weeks in patients with metastatic/recurrent TNBC. The primary endpoint was overall response rate (ORR). RESULTS: All nine patients enrolled were germline BRCA wild-type (BRCAwt) and had at least one prior treatment. One partial response (PR) was observed (ORR of 11.1%). Four patients experienced stable disease. The median progression-free survival (PFS) was 86 days (range 17 to 159 days). Grade 3/4 treatment-related adverse events included afebrile neutropenia (n = 8; 88.9%), anemia (n = 3; 33.3%), and thrombocytopenia (n = 1; 11.1%). Pharmacodynamic studies showed prexasertib treatment induced DNA damage in peripheral immune cells and demonstrated a decrease in activated/reinvigorated CD8 T cells; however, the one patient with a PR showed evidence of T-cell recovery. CONCLUSION: Prexasertib monotherapy had modest clinical efficacy in BRCAwt TNBC. Further studies of prexasertib in combination with other agents are needed.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Data on the link between total and individual dairy product consumption and risk of breast cancer are controversial, especially in Middle Eastern populations. OBJECTIVE: This study aimed to evaluate the association between total and individual dairy product consumption and odds of breast cancer among Iranian women. METHODS: In the context of a population-based case-control study on 350 patients with pathologically confirmed cases of breast cancer and 700 age-matched controls, we assessed dietary intakes using a 106-item semi-quantitative dish-based food frequency questionnaire. Consumption of low- and high-fat dairy products as well as dietary intakes of pasteurized milk, cheese and yogurt were computed. RESULTS: Mean (± SD) age and BMI of study participants was 62.4 ± 10.8 y and 24.3 ± 5.2 kg/m2, respectively. After controlling for potential covariates, individuals in the top quartile of low-fat dairy product intake were less likely to have breast cancer than those in the bottom quartile (OR 0.08; 95% CI 0.05-0.16), while those with the highest intake of high-fat dairy intake had greater odds for breast cancer than those with the lowest intake (OR 8.62; 95% CI 4.78-15.55). Despite lack of a significant association between yogurt and cheese consumption and odds of breast cancer, we found a positive association between total milk intake (OR 1.76; 95% CI 1.16-2.65) and breast cancer, after controlling for potential confounders. CONCLUSION: Low-fat dairy intake was inversely and high-fat dairy consumption was positively associated with breast cancer. No significant association was found between yogurt and cheese consumption and breast cancer, while total milk intake was associated with a greater odds of breast cancer.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Limited evidence exists regarding the association between dietary calcium intake and risk of glioma. The objective of this study was to determine the relationship between dietary calcium intake and risk of glioma in Iranian adults. In this hospital-based case-control study, we enrolled 128 newly-diagnosed cases of glioma and 256 age- and sex-matched controls. Patients with pathologically confirmed glioma (without any other cancers) were selected. Dietary intakes of study participants were collected through a validated 126-item food-frequency questionnaire. Dietary calcium intake was computed from dairy products in the questionnaire. Participants were categorized into quartiles of dietary calcium intake. Binary logistic regression was used to examine the association between dietary calcium intake and glioma. Higher dietary intake of calcium was associated with younger age, long duration of cell phone use, and frequent canned foods intake. After taking age, sex, and energy intake into account, participants with the greatest dietary calcium intake had 84% lower odds of glioma than those with the lowest intake [odds ratio (OR): 0.16; 95% confidence interval (CI), 0.07-0.37]. Further adjustment for other potential confounders including nutrient intakes did not significantly alter the association (OR: 0.22; 95% CI, 0.08-0.64). Even after additional adjustment for BMI, we found a significant inverse association between dietary calcium intake and odds of glioma (OR: 0.23; 95% CI, 0.08-0.65). We found an inverse protective association between high dietary calcium intake and odds of glioma. Further prospective cohort studies are needed to confirm these findings.

RESUMO

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.

RESUMO

The association between habitual intake of the "dietary approaches to stop hypertension" (DASH) eating plan and sarcopenia has received limited attention. The present study aimed to investigate the association between adherence to DASH dietary pattern and sarcopenia and its components including muscle mass, muscle strength, and muscle performance among community-dwelling older adults population. This population-based cross-sectional study was performed in 2011 among 300 older people (150 men and 150 women) aged ≥ 55 years, who were selected using cluster random sampling method. Dietary intake of study participants were examined by the use of a Block-format 117-item food frequency questionnaire (FFQ). The DASH score was constructed based on eight main foods and nutrients emphasized or minimized in the DASH diet. All components of sarcopenia was measured using standard protocols and sarcopenia was defined based on both former and new European Working Group on Sarcopenia in Older People (EWGSOP) guidelines. Mean age and BMI of study participants were 66.7 ± 7.7 years and 27.3 ± 4.2 kg/m2, respectively. Totally, 31 individuals meet the criteria of EWGSOP2-sarcopenia. We found no significant association between adherence to the DASH diet and EWGSOP2-sarcopenia either before (OR 1.08; 95% CI 0.45-2.54) or after adjustment for potential confounders (OR 1.04; 95% CI 0.39-2.75). The same findings were obtained in the gender-stratified analyses (men: OR 2.29; 95% CI 0.39-13.29 and women: 0.75; 95% CI 0.23-2.45). In conclusion, we found that adherence to the DASH-style diet was not significantly associated with odds of sarcopenia. Future prospective studies are required to confirm these findings.

RESUMO

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.

RESUMO

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.

RESUMO

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.
