Association between neighborhood household income and inpatient atrial fibrillation outcomes.

BACKGROUND: The impact of socioeconomic status on the clinical outcomes of patients admitted to the hospital for atrial fibrillation (AF) is not well described. OBJECTIVE: The purpose of this study was to determine the association between median neighborhood household income (mNHI) and clinical outcomes among patients admitted to the hospital for AF. METHODS: We retrospectively analyzed primary AF hospitalizations from the United States National Inpatient Sample between 2016 and 2020. The analyzed sample was divided into quartiles based on the mNHI in the zip code of the patient's residence. The lowest quartile was used as the reference category. Study outcomes included inpatient procedure utilization (ablation, cardioversion, percutaneous left atrial appendage closure), length of stay, cost, mortality, and disposition. Weighted multivariable logistic and linear regression, adjusting for multiple patient and hospital-level characteristics, was performed. RESULTS: Patients in the highest mNHI quartile had lower comorbidity burden, lower in-hospital mortality (odds ratio [OR] 0.78; 95% confidence interval [CI] 0.7-0.87; P <.001), lower discharges to care facility (OR 0.86; 95% CI 0.83-0.9; P <.001), shorter length of stay (adjusted mean difference -0.26; 95% CI -0.30 to -0.22; P <.001), higher procedure utilization, and higher health care costs ($12,124 vs $10,018) compared to the lowest mNHI quartile patients. CONCLUSION: We identified significantly higher in-hospital mortality and lower procedural/resource utilization in patients living in lower-income neighborhoods compared to higher-income neighborhoods. Further research is needed to better understand the drivers of these disparities and the strategies to improve health care disparities between socioeconomic groups.

Dietary riboflavin intake in relation to psychological disorders in Iranian adults: an observational study.

Findings of earlier investigations on association between dietary riboflavin intake and psychological disorders are contradictory. Therefore, the relation between dietary riboflavin intake and depression, anxiety, and psychological distress was assessed in Iranian adults. In this cross-sectional study, dietary intakes of 3362 middle-aged adults were collected using a validated dish-based food frequency questionnaire. Daily intake of riboflavin for each participant was calculated by summing up the amount of riboflavin contents of all foods and dishes. Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ), as validated questionnaires among Iranians, have been applied to assess depression, anxiety, and psychological distress. After considering potential confounders, adults in the top energy-adjusted quartile of riboflavin intake, compared to the bottom quartile, had decreased odds of depression (OR = 0.66; 95%CI 0.49, 0.88), anxiety (OR = 0.64; 95%CI 0.44, 0.94) and high psychological distress (OR = 0.65; 95%CI 0.48, 0.89). Stratified analysis by sex revealed that men in the forth quartile of riboflavin intake, compared with those in the first quartile, had respectively 51 and 55% lower odds of depression (OR = 0.49; 95%CI 0.29, 0.83) and anxiety (OR = 0.45; 95%CI 0.21, 0.95). In women, riboflavin intake was significantly associated with lower odds of psychological distress (OR = 0.67; 95%CI 0.46, 0.98). An inverse relation was observed between dietary riboflavin intake and chance of psychological disorders in Iranian adults. High intake of riboflavin decreased the chance of depression and anxiety in men and high psychological distress in women. More prospective studies are needed to confirm these findings.

Relationship between Depression and Constipation: Results from a Large Cross-sectional Study in Adults.

Background/Aims: Accumulating evidence based on a few studies suggests a relationship between depression and functional constipation. This study examined whether depression is associated with a higher risk of functional constipation and whether it is gender specific. Methods: This cross-sectional study was carried out on 3,362 adults aged 18-55 years. In this study, functional gastrointestinal symptoms were determined using an Iranian reliable and valid version of the modified Rome III questionnaire. The Iranian validated version of the hospital anxiety and depression scale was used to evaluate the psychological health. Scores of eight or more on the depression subscale in the questionnaire were considered the presence of depression. Simple and multiple binary logistic regression were used for data analysis. Results: The mean±SD age of participants was 36.29±7.87 years, and 58.5% were female. The prevalence of depression and constipation in the study sample was 28.6% and 23.9%, respectively. In the full adjusted model, in the total sample, depressed people showed a significantly higher risk of constipation; adjusted OR (AOR), 1.69 (95% CI, 1.37-2.09). Although a significant association was observed between depression and constipation in both genders, the association was stronger in men than women (AOR, 2.28; 95% CI, 1.50, 3.63 vs. AOR, 1.55; 95% CI, 1.21, 1.99). Conclusions: These study findings showed that depressed people are at a significantly higher risk of being affected by constipation. The current study findings justify the importance of mental health evaluations in all patients with functional gastrointestinal disorders, particularly among constipated individuals.

The Relationship Between Linoleic Acid Intake and Psychological Disorders in Adults.

Background: The association between linoleic acid (LA) intake and mental disorders has not been extensively studied in Middle-Eastern populations. We investigated the association between LA intake and the prevalence of depression, anxiety, and psychological distress in a large group of Iranian adults. Methods: This cross-sectional study was conducted on 3,362 middle-aged adults. LA intake was determined through a validated dish-based 106-item semiquantitative food frequency questionnaire (FFQ). The validated Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ) were used to define psychological disorders. Results: The prevalence of depression, anxiety, and psychological distress among the study population was 28.6, 13.6, and 22.6%, respectively. After adjustment for potential confounders, individuals in the top quartile of LA intake had 41% more likely to be depressed compared to those in the bottom quartile (OR = 1.41, 95% CI: 1.02-1.95). Stratified analysis by sex revealed that men in the fourth quartile of LA intake, compared to the first quartile, had 80% higher odds of depression, after considering all potential confounders (OR = 1.80, 95% CI: 1.01-3.19). More consumption of LA was also associated with higher odds of depression in older adults (OR = 2.45, 95% CI: 1.46-4.10) and normal-weight individuals (OR = 1.75, 95% CI: 1.13-2.72). Additionally, higher intake of LA was related to 90% higher odds of psychological distress in older participants (OR = 1.90, 95% CI: 1.08-3.36). No significant relation was found between LA intake and anxiety. Conclusion: We found that higher intake of LA, as percentage of energy, was positively associated with depression, especially in men, older adults, and normal-weight subjects. Higher intake of LA was also related to higher odds of psychological distress in older individuals. More studies, particularly prospective cohorts, are needed to confirm these findings.

A Body Shape Index and Body Roundness Index in Relation to Anxiety, Depression, and Psychological Distress in Adults.

Background: Despite the large evidence on the association between obesity and psychological disorders, studies investigating new anthropometric indices in relation to mental health are limited. We aimed to explore the association between A Body Shape Index (ABSI) and Body Roundness Index (BRI) and common psychological disorders (anxiety, depression, and psychological distress) among Iranian adults. Methods: In this cross-sectional investigation, anthropometric measures of 3213 Iranian adults were gathered using a validated self-reported questionnaire. ABSI and BRI values of participants were calculated through pre-defined formulas. General Health Questionnaire (GHQ) and Hospital Anxiety and Depression Scale (HADS) validated for Iranians were used to assess psychological distress, anxiety, and depression. Results: Mean age of participants was 36.6 ± 7.73, and 62.8% of them were women. ABSI and BRI were higher in subjects with anxiety and psychological distress. Also, depressed participants had higher BRI. After considering potential confounders, individuals in the last tertile of ABSI, compared to the first tertile, had higher odds of anxiety (OR: 1.41, 95%CI: 1.04, 1.93) and psychological distress (OR: 1.39, 95%CI: 1.09, 1.79). Also, a marginal association was found between the highest category of ABSI and depression (OR: 1.27; 95%CI: 1.00, 1.61). In the sex-stratified analysis, ABSI was positively related to odds of anxiety (OR: 1.58; 95%CI; 1.12, 2.22), depression (OR: 1.40; 95%CI; 1.07, 1.84), and psychological distress (OR: 1.51; 95%CI; 1.13, 2.01) among women, but not men. We failed to find any significant association between BRI and depression, anxiety and psychological distress. Conclusion: We found that ABSI was associated with anxiety, depression and psychological distress among females, but not males. However, we did not find a significant relation between BRI and the outcomes. Further prospective studies are required to confirm our findings.

Validation of Self-Assessed Form of Diagnostic Criteria for Psychosomatic Research Adapted from Diagnostic Criteria for Psychosomatic Research - Structured Interview.

Background: As the diagnostic criteria for psychosomatic research-structured interview (DCPR-SI) is a rater-assessed questionnaire, it has not been used vastly in community-based studies and clinics. Describing and investigating self-assessed form of DCPR are an attempt to apply it easier and more worthwhile for medical settings. The aim of this study was to describe and present self-assessed form of DCPR self-assessed (DCPR-SA) and test its validity and reliability. Materials and Methods: The DCPR-SI was translated to Persian according to the best practice methodology and the guideline for adaptation of self-report measures. In this cross-sectional study, 540 patients and healthy individuals were recruited and answered DCPR-SA and some related questionnaires. Inter-rater (test-interview) and test-retest reliability were determined. Construct, concurrent, discriminant, and known-group validity were tested. Results: The kappa coefficients were expressed substantial and almost perfect agreement (0.617-0.784, P ≤ 0.05). In addition, phi correlation coefficients were indicated adequate test-retest reliability for each cluster (0.548-0.754, P ≤ 0.05). Three domains (anxiety-related symptoms, functional symptoms, and dysfunctional traits and emotional patterns) were confirmed by factor analysis. The results of the discriminate validity analysis were promising. Conclusion: The findings show that the DCPR-SA is valid and reliable and can be used by medical professionals as a psychosomatic screening tool and can be used properly in Persian-speaking population.

Coffee and caffeine intake in relation to symptoms of psychological disorders among adults.

OBJECTIVE: Given that there is an inconsistency in the findings related to the relationship between coffee and caffeine consumption and symptoms of psychological disorders, we performed a cross-sectional analysis to examine the association between coffee and caffeine intake and symptoms of psychological disorders among adults. DESIGN: In this cross-sectional study, 3362 participants were included. We assessed the coffee and caffeine intakes using a self-completed food frequency questionnaire (FFQ). Symptoms of depression, anxiety, and psychological distress were assessed using HADS and GHQ screening tools. RESULTS: The mean age of participants in this study was 36.2±7.8 years. After controlling for potential confounders, individuals who consumed coffee weekly or more had a significantly lower odds of symptoms of depression (OR: 0.67; 95% CI: 0.46-0.96) and symptoms of anxiety (OR: 0.57; 95% CI: 0.34-0.95) compared with those who did not consume coffee. However, no significant association was found between coffee intake and symptoms of psychological distress (OR: 0.98; 95%CI: 0.68-1.42). No significant relationship was found between caffeine intake and odds of symptoms of depression (OR: 0.94; 95% CI: 0.75-1.16), symptoms of anxiety (OR: 0.90; 95% CI: 0.67-1.20), and symptoms of psychological distress (OR: 1.13; 95% CI: 0.89-1.42). CONCLUSION: Compared with lack of coffee intake, weekly or more coffee consumption might be correlated with symptoms of depression and anxiety.

The association of plant-based dietary patterns and psychological disorders among Iranian adults.

BACKGROUND: Plant-based dietary pattern, a new scoring system, has had a favorable relationship with the risk of chronic diseases, however, the associations with mental health are long disputed. Thus, we examined the association between an overall plant-based diet (PDI), healthy plant-based diet (hPDI), and unhealthy plant-based diet (uPDI) and psychological disorders in adult Iranian patients. METHODS: In this large cross-sectional study, 3,362 Iranian men and women were recruited. Dietary data were gathered using a validated and reliable Willett format food frequency questionnaire (FFQ). Plant-based dietary pattern scores were calculated based on the method of Satija et al. Psychological profile assessment was done using the validated hospital anxiety and depression scale (HADS) and the general health questionnaire (GHQ). RESULTS: A total number of 943, 448, and 760 participants who suffered from depression, anxiety, and psychological distress, respectively, were identified. In the multivariable-adjusted analysis, participants in the highest category of PDI and hPDI scores had lower odds of having depression and anxiety than those in the lowest category. This association was also found between hPDI and psychological distress (OR: 0.51, 95% CI: 0.38-0.68). In contrast, higher scores of uPDI was associated with increased odds of anxiety (OR: 1.60, 95% CI: 1.06-2.42) and psychological distress (OR: 1.38, 95% CI: 1.01-1.90). LIMITATION: The cross-sectional study design. CONCLUSION: Our results indicated that greater adherence to the overall plant-based diet and healthy plant-based diet was inversely associated with psychological disorders, while following unhealthy plant-based diet increased the risk of anxiety and psychological distress.

Depression, anxiety and stress, comorbidity evaluation among a large sample of general adults: results from SEPAHAN study

Depression, anxiety and stress are common psychological disorders (PDs).This study aimed to assess the odds of co-occurrence of mentioned PDs in total sample and different levels of socio-demographic characteristics, specifically among a large sample of general adults.Ina cross-sectional, community-based study conducted among 4763 Iranian adults, depression and anxiety were assessed with Hospital Anxiety and Depression Scale (HADS) and stress with General Health Questionnaire (GHQ). The loglinear analysis was applied to investigate their comorbidities. Based on selected models with pair-comorbidity of anxiety with stress, depression with stress, and anxiety with depression, the results showed the odds of comorbidity between anxiety and depression (odds ratio (OR) =12.29, 95%CI: 9.58-15.80), depression and stress (OR = 7.80, 95%CI:6.55-10.18), and stress and anxiety (OR = 4.62, 95%CI:3.71-5.75). Also, ORs of pair-comorbidities were the same, except between stress and anxiety for men compared to women (adjusted-OR = 6.47, 95%CI: 4.44-9.49 versus 3.85, 95%CI:2.95-5.00) and comorbidity between stress and depression for the participants withlower than 40 years compared to others (adjusted-OR = 9.03, 95%CI: 7.17-11.36 versus 6.41, 95%CI: 4.90-8.41), p< 0.05. Stress comorbidity with depression was higher level than other pair-comorbidities. Obvious discrepancies were also observed in terms of ORs of pair-comorbidities between three mentioned disorders in different levels of SDCs.

Dietary methyl donor micronutrients intake in relation to psychological disorders in adults.

Previous investigations have mostly studied an individual methyl donor nutrient in relation to psychological disorders and the findings were inconsistent. We investigated the association of methyl donor micronutrients (folate, B6, B12, choline, betaine and methionine) with psychological disorders in Iranian adults. In this cross-sectional study, dietary intakes of 3299 adults were collected using a validated food frequency questionnaire. Methyl donor micronutrient score (MDMS) was calculated based on energy-adjusted deciles of each nutrient. Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ), validated for Iranians, have been applied to assess depression, anxiety and psychological distress. Participants had a mean age of 36·3 ± 7·9 years, of whom 58·5 % were women. After considering potential confounders, adults in the top quartile of MDMS, compared to the bottom one, had decreased odds of anxiety (OR: 0·53, 95 % CI: 0·37, 0·75), depression (OR: 0·75, 95 % CI: 0·58, 0·97) and psychological distress (OR: 0·61, 95 % CI: 0·46, 0·80). Among women, the top quartile of MDMS was protectively associated with anxiety (OR: 0·60, 95 % CI: 0·40, 0·90), depression (OR: 0·68, 95 % CI: 0·50, 0·93) and psychological distress (OR: 0·53, 95 % CI: 0·38, 0·74). Overweight and obese subjects in the highest quartile of MDMS had a 67 %, 35 % and 53 % lower odds of anxiety (95 % CI: 0·20, 0·56), depression (95 % CI: 0·44, 0·94) and psychological distress (95 % CI: 0·31, 0·70), respectively. We found that high consumption of methyl donor micronutrients was related to a reduced odds of psychological disorders, especially in women and overweight or obese individuals.

Red and White Meat Intake in Relation to Mental Disorders in Iranian Adults.

Background: The association between meat consumption and mental disorders is less investigated in Iranian population. We examined the association between meat consumption and prevalence of symptoms of depression, anxiety, and psychological distress in Iranian adults. Methods: This cross-sectional study included 3,362 participants aged 18-55 years old. A dish-based 106-item semiquantitative food frequency questionnaire (FFQ) was used to assess usual dietary intake of study population. Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ), all validated in Iranian population, were applied to collect data on symptoms of anxiety, depression, and psychological distress, respectively. Results: The prevalence of symptoms of depression, anxiety, and psychological distress in the study population was 28.6, 13.6, and 22.6%, respectively. After considering potential confounders, individuals in the top quartile of red meat intake had 43% increased risk of depression symptoms [odds ratio (OR) = 1.43; 95% CI: 1.09-1.89] compared to those in the first quartile. No significant relation was observed between red meat intake and anxiety or psychological distress symptoms. White meat consumption was not associated with mental disorders. Stratified analysis by sex showed that male participants in the highest quartile of red meat intake had 92% greater risk of depression symptoms (95% CI: 1.17-3.15) than those individuals in the lowest category. Red and white meat intake was not associated with mental disorders in women. In overweight or obese individuals, despite lack of any association between red meat intake and mental disorders, high intake of white meat was associated with a lower odds of psychological distress symptoms (OR = 0.64; 95% CI: 0.42-0.99) and a lower risk of depression symptoms (OR = 0.68; 95% CI: 0.45-1.00). In normal-weight participants, those in the highest quartile of red meat intake had greater odds for depression symptoms than those in the lowest quartile (OR = 1.66; 95% CI: 1.14-2.42). Conclusions: We found that red meat consumption was associated with increased risk of depression symptoms, especially in men, and normal-weight participants. In overweight or obese participants, white meat intake was inversely associated with psychological distress symptoms.

Consumption of Dietary Fiber in Relation to Psychological Disorders in Adults.

Background: Previous observational studies suggested a relationship between dietary fiber consumption and mental health, but the findings were conflicting. We evaluated the link between dietary fiber intake and prevalence of depression, anxiety, and psychological distress among a large population of Iranian adults. Methods: A cross-sectional study among 3,362 Iranian adults working in 50 health centers was done. Data of dietary intakes were collected through a validated semiquantitative dish-based 106-item food frequency questionnaire (FFQ). Anxiety, depression, and psychological distress were defined based on the Iranian validated version of Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ). Results: After adjustment for potential confounders, participants in the top quartile of total dietary fiber intake had a 33% and 29% lower risk of anxiety and high psychological distress [odds ratio (OR): 0.67; 95% CI: 0.48, 0.95 and OR: 0.71; 95% CI: 0.53, 0.94, respectively] compared to the bottom quartile of intake. The highest total dietary fiber intake was also inversely related to a lower risk of depression in women (OR: 0.63; 95% CI: 0.45, 0.88) but not in men. Among overweight or obese participants, higher intake of dietary fiber was related to a decreased risk of high psychological distress (OR: 0.52; 95% CI: 0.34, 0.79). A high level of dietary fiber intake was related to a lower risk of anxiety in normal-weight individuals (OR: 0.50; 95% CI: 0.31, 0.80). Conclusion: Significant inverse associations between total dietary fiber intake with anxiety and high psychological distress were found in Iranian adults. More consumption of dietary fiber was also related to reduced odds of depression in women. More investigations with prospective nature are needed to affirm these findings.

Relationship between obesity and depression, anxiety and psychological distress among Iranian health-care staff.

BACKGROUND: Psychological-related disorders such as obesity are a key contributor to morbidity and mortality. AIMS: To assess the association between general and abdominal obesity with depression and anxiety among Iranian health-care staff. METHODS: This cross-sectional study was conducted under the framework of the Study on the Epidemiology of Psychological Alimentary Health and Nutrition. A total of 4361 Iranian health-care staff were analysed for general obesity and 3213 for central obesity. Overweight and obesity was defined as body mass index 25.0-29.9 and ≥ 30.0 kg/m², respectively. Abdominal obesity was defined as waist circumference (WC) ≥ 88 cm for females and ≥ 102 cm for males. The Iranian validated versions of the Hospital Anxiety and Depression Scale and the General Health Questionnaire were used to assess depression and anxiety. RESULTS: Stratified analysis by sex revealed no significant relationship between general obesity, depression and anxiety among males. However, we found an inverse association between abdominal obesity (WC > 102 cm) and severe depression among males. In females, abdominal obesity was significantly associated with anxiety, before and after taking confounders into account. No significant association was seen between abdominal obesity and psychological distress in either sex after controlling for potential confounders. CONCLUSIONS: Abdominal obesity was associated with anxiety in Iranian adult females but not in males. Further studies, particularly prospective research, are required to confirm these findings.

Breakfast skipping alone and in interaction with inflammatory based quality of diet increases the risk of higher scores of psychological problems profile in a large sample of Iranian adults.

The authors investigate the association of breakfast skipping and its interaction with a dietary inflammatory index (DII) with the severity of psychological disorders. A total of 2876 Iranian general adults were enrolled in this cross-sectional study. Psychological problems profile score was calculated using the regression method in the framework of factor analysis based on depression, anxiety and psychological distress. The higher scores indicate more severity of mental problem. The frequency of breakfast eating in a week was assessed. Dietary intakes were assessed using a food-frequency questionnaire and twenty-seven items were included in the calculation of DII. In the crude model, individuals who ate breakfast seldom had the highest odds for having worse psychological problems profile (OR 3⋅59; 95 % CI 2⋅52, 5⋅11). Adjustment for various confounders did not change the associations (OR 3⋅35; 95 % CI 2⋅11, 5⋅32). In the adjusted multinomial logistic regression model, participants with high DII (>median) who skipped breakfast had highest risk of being in the higher tertiles of psychological problems profile compared with those who had low DII (

Association of acute kidney injury with outcomes in patients undergoing percutaneous left atrial appendage closure.

OBJECTIVES: Using a large nationally representative database, we aimed to examine risk factors for acute kidney injury (AKI) and its association with outcomes in patients undergoing percutaneous left atrial appendage closure (LAAC). BACKGROUND: Previous small-scale studies have reported poor outcomes with AKI following percutaneous LAAC. METHODS: We queried the Nationwide Readmission Database to identify LAAC procedures performed from 2016 to 2017. Multivariable logistic and linear regression models were used to identify risk factors for AKI and determine the association between AKI and clinical outcomes. The primary outcome of interest was in-hospital mortality. RESULTS: Of 20,703 patients who underwent LAAC during the study period, 1,097 (5.3%) had a diagnosis of AKI. Chronic kidney disease, non-elective admission, coagulopathy, weight loss, prior coronary artery disease, heart failure, diabetes mellitus, and anemia were independently associated with an increased risk of AKI after LACC. In patients undergoing LAAC, AKI was associated with an increased risk of in-hospital mortality (adjusted odds ratio [aOR], 16.01; 95% CI, 8.48-30.21), stroke/transient ischemic attack (aOR, 2.50; 95% CI, 1.69-3.70), systemic embolization (aOR, 3.78; 95% CI, 1.64-8.70), bleeding/transfusion (aOR, 1.96; 95% CI, 1.50-2.56), vascular complications (aOR, 3.53; 95% CI, 1.94-6.42), pericardial tamponade requiring intervention (aOR, 6.83; 95% CI, 4.37-10.66), index length of stay (adjusted parameter estimate, 7.46; 95% CI, 7.02-7.92), and 180-day all-cause readmissions (aOR, 1.43; 95% CI, 1.09-1.88). CONCLUSION: AKI in the setting of LAAC is uncommon but is associated with poor clinical outcomes. Further studies are needed to determine if a similar association exists for long-term outcomes.

Dietary intake of branched-chain amino acids in relation to depression, anxiety and psychological distress.

BACKGROUND: There is no previous study that examined the association between branched-chain amino acids (BCAAs) intake and odds of psychological disorders. The aim of this study was to investigate the association between dietary BCAAs and odds of psychological disorders including depression, anxiety, and psychological distress in a large sample of Iranian adults. METHODS: In this cross-sectional study on 3175 Iranian adults aged 18-55 years, a validated food frequency questionnaire was used to assess dietary intakes. BCAAs intake was computed by summing up the amount of valine, leucine, and isoleucine intake from all food items in the questionnaire. Psychological health was examined through the use of Iranian validated version of the Hospital Anxiety and Depression Scale (HADS). Psychological distress was assessed using General Health Questionnaire (GHQ). For depression and anxiety, scores of 8 or more on either subscale were considered as psychological disorders and scores of 0-7 were defined as "normal". In terms of psychological distress, the score of 4 or more was defined as psychological distress. RESULTS: Mean age of study participants was 36.2 ± 7.8 years. Overall, 26.4% (n = 837) of study subjects had depression, 11.9% (n = 378) had anxiety and 20.9% (n = 665) were affected by psychological distress. After controlling for potential confounders, participants in the highest tertile of total BCAAs intake had lower odds of depression (OR: 0.76; 95% CI: 0.60-0.96) and anxiety (OR: 0.66; 95% CI: 0.47-0.91) compared with those in the lowest tertile. Participants in the top tertile of valine intake had a lower odds of depression (OR: 0.76; 95% CI: 0.60-0.96) and anxiety (OR: 0.65; 95% CI: 0.47-0.90) compared with those in the bottom tertile. A significant inverse association was also seen between leucine intake and depression (OR: 0.77; 95% CI: 0.61-0.98) and anxiety (OR: 0.66; 95% CI: 0.47-0.91). In addition, a significant inverse association was observed between isoleucine intake and odds of depression (OR: 0.75; 95% CI: 0.59-0.95) and anxiety (OR: 0.62; 95% CI: 0.45-0.86). There was no significant association between isoleucine intake and odds of psychological distress. CONCLUSION: Evidence indicating an inverse association between dietary intake of BCAAs and odds of depression and anxiety was found. Prospective studies are required to confirm these findings.

Determinants of outcome impact of vein of Marshall ethanol infusion when added to catheter ablation of persistent atrial fibrillation: A secondary analysis of the VENUS randomized clinical trial.

BACKGROUND: The Vein of Marshall Ethanol for Untreated Persistent AF (VENUS) trial demonstrated that adding vein of Marshall (VOM) ethanol infusion to catheter ablation (CA) improves ablation outcomes in persistent atrial fibrillation (AF). There was significant heterogeneity in the impact of VOM ethanol infusion on rhythm control. OBJECTIVE: The purpose of this study was to assess the association between outcomes and (1) achievement of bidirectional perimitral conduction block and (2) procedural volume. METHODS: The VENUS trial randomized patients with persistent AF (N = 343) to CA combined with VOM ethanol or CA alone. The primary outcome (freedom from AF or atrial tachycardia [AT] lasting longer than 30 seconds after a single procedure) was analyzed by 2 categories: (1) successful vs no perimitral block and (2) high- (>20 patients enrolled) vs low-volume centers. RESULTS: In patients with perimitral block, the primary outcome was reached 54.3% after VOM-CA and 37% after CA alone (P = .01). Among patients without perimitral block, freedom from AF/AT was 34.0% after VOM-CA and 37.0% after CA (P = .583). In high-volume centers, the primary outcome was reached in 56.4% after VOM-CA and 40.2% after CA (P = .01). In low-volume centers, freedom from AF/AT was 30.77% after VOM-CA and 32.61% after CA (P = .84). In patients with successful perimitral block from high-volume centers, the primary outcome was reached in 59% after VOM-CA and 39.1% after CA (P = .01). Tests for interaction were significant (P = .002 for perimitral block and P = .04 for center volume). CONCLUSION: Adding VOM ethanol infusion to CA has a greater impact on outcomes when associated with perimitral block and performed in high-volume centers. Perimitral block should be part of the VOM procedure.

Adherence to Mediterranean dietary pattern is inversely associated with depression, anxiety and psychological distress.

Background: Few studies have assessed adherence to the Mediterranean diet in relation to psychological health, in particular in the Middle East.Objective: To examine the association between adherence to Mediterranean dietary pattern and prevalence of psychological disorders among a large population of Iranian adults.Design: In this cross-sectional study on 3172 Iranian adults aged 18-55 years, we used a validated food frequency questionnaire for the assessment of dietary intakes. Adherence to the Mediterranean dietary pattern was examined using the Trichopoulou et al. method. To assess psychological health, the Iranian validated version of the Hospital Anxiety and Depression Scale (HADS) was used. Psychological distress was assessed through the use of General Health Questionnaire (GHQ).Results: Mean age of study participants was 36.54 ± 4.97 years. After controlling for potential confounders, participants with the greatest adherence to the Mediterranean diet had lower odds for depression (OR: 0.60, 95% CI: 0.46-0.78), anxiety (OR: 0.61, 95% CI: 0.42-0.86) and psychological distress (OR: 0.60, 95% CI: 0.45-0.79) compared with those with the lowest adherence. When the association with components of Mediterranean diet was examined, we found that high intake of fruits and vegetables was associated with a lower odds of depression, anxiety and psychological distress. In contrast, high intake of grains was positively associated with depression, anxiety and psychological distress.Conclusion: We found evidence indicating an inverse association between adherence to Mediterranean dietary pattern and odds of psychological disorders including depression, anxiety and psychological distress.

Empirically derived food-based dietary inflammatory index is associated with increased risk of psychological disorders in women.

Purpose/introduction: There is no study on the association of empirically derived food-based dietary inflammatory index (FDII) and risk of psychological disorders. We investigated the association between FDII and odds of psychological disorders in Iranian adults.Methods and materials: In this cross-sectional study, data on dietary intakes of 3363 Iranian adult participants were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire. FDII score was constructed based on participants' dietary intakes of 28 pre-defined food groups. The Iranian validated version of Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ) was used to assess psychological disorders. Depression, anxiety and psychological distress were defined based on standard criteria.Results: After controlling for potential confounders, participants in the top quintile of FDII score had a greater odds of depression (OR: 1.49; 95% CI: 1.08-2.06), anxiety (OR: 1.92; 95% CI: 1.24-2.96), and psychological distress (OR: 1.55; 95% CI: 1.10-2.19) compared with those in the bottom quintile. When we did the analyses stratified by gender, we found a significant positive association between FDII score and depression (OR: 1.57; 95% CI: 1.04-2.35), anxiety (OR: 1.99; 95% CI: 1.19-3.34), and psychological distress (OR: 1.68; 95% CI: 1.10-2.56) among women comparing the highest and the lowest quintiles. We found no significant association between FDII score and psychological disorders in men.Conclusion: We found that greater FDII score was positively associated with psychological disorders. In the gender-stratified analysis, this was seen in women but not in men.
