Introduction: The field of nutritional psychiatry is a fast-growing one. Although initially, it focused on the effects of vitamins and micronutrients in mental health, in the last decade, its focus also extended to the dietary patterns. The possibility of a dietary cost-effective intervention in the most common mental disorder, depression, cannot be overlooked due to its potential large-scale impact. Method: A classic review of the literature was conducted, and studies published between 2010 and 2018 focusing on the impact of dietary patterns in depression and depressive symptoms were included. Results: We found 10 studies that matched our criteria. Most studies showed an inverse association between healthy dietary patterns, rich in fruits, vegetables, lean meats, nuts and whole grains, and with low intake of processed and sugary foods, and depression and depressive symptoms throughout an array of age groups, although some authors reported statistical significance only in women. While most studies were of cross-sectional design, making it difficult to infer causality, a randomized controlled trial presented similar results. Discussion: he association between dietary patterns and depression is now well-established, although the exact etiological pathways are still unknown. Dietary intervention, with the implementation of healthier dietary patterns, closer to the traditional ones, can play an important role in the prevention and adjunctive therapy of depression and depressive symptoms. Conclusion: More large-scale randomized clinical trials need to be conducted, in order to confirm the association between high-quality dietary patterns and lower risk of depression and depressive symptoms.

Abstract Background and study aims Bowel preparation for colonoscopy is frequently inadequate in hospitalized patients. We explored the impact of specific verbal instructions on the quality of inpatients bowel preparation and factors associated with preparation failure. Patients and methods Randomized (1:1), two strata (mobilized vs. bedridden; 3:2) trial of consecutive inpatients from four tertiary centers, who received either specific, verbal instructions or the standard of care (SOC) ward instructions about bowel preparation. The rate of adequate bowel preparation (Boston Bowel Preparation Score [BBPS] ≥ 6, no segment < 2) comprised the primary endpoint. Mean BBPS score, good (BBPS score ≥ 7, no segment score < 2) and excellent (BBPS = 9) were among secondary endpoints. Results We randomized 300 inpatients (180 mobile) aged 71.7 ± 15.1 years in the intervention (49.7 %) and SOC (50.3 %) groups, respectively. Overall, more patients in the intervention group achieved adequate bowel preparation, but this difference did not reach statistical significance neither in the intention-to-treat [90/149 (60.4 %) vs. 82/151 (54.3 %); P = 0.29] nor in the per-protocol analysis [90/129 (69.8 %) vs. 82/132 (62.1 %); P = 0.19]. Overall BBPS score did not differ statistical significantly in the two groups, but the provision of specific verbal instructions was associated with significant higher rates of good (58.1 % vs. 43.2 %; P = 0.02) and excellent (31.8 % vs. 16.7 %; P = 0.004) bowel preparation compared to the SOC group. Administration of same-day bowel preparation and patient American Society of Anesthesiologists score > 2 were identified as risk factors for inadequate bowel preparation. Conclusions Provision of specific verbal instructions did not increase the rate of adequate bowel preparation in a population of mobilized and bedridden hospitalized patients.

Abstract The availability of cheap Wi-Fi internet connections has encouraged schools to adopt Web 2.0 platforms for teaching, with the intention of stimulating students’ academic achievement and participation in school. Moreover, during the recent explosion of the SARS-CoV-2 crisis that forced many countries to close schools (as well as offices and factories), the widespread diffusion of these applications kept school systems going. Despite their widespread use as teaching tools, the effect of adopting Web 2.0 platforms on students’ performance has never been rigorously tested. We fill this gap in the literature by analyzing the impact of using Twitter as a teaching tool on high school students’ literature skills. Based on a large-scale, randomized controlled trial that involved 70 schools and about 1,500 students, we find that using Twitter to teach literature has an overall negative effect on students’ average achievement, reducing standardized test scores by about 25 percent of a standard deviation. The negative effect is stronger on students who usually perform better.

The Impact

Objective: To provide guidance to criminologists for conducting experiments in light of two common discouraging factors: the belief that they are overly time-consuming and the belief that they can compromise the ethical principles of human subjects’ research. Method: A case study approach is used, based on a large-scale randomized controlled trial experiment in which we exposed participants to a 5-s TASER shock, to describe how the authors overcame ethical, methodological, and logistical difficulties. Results: We derive four pieces of advice from our experiences carrying out this experimental trial: (1) know your limitations, (2) employ pilot testing, (3) remain flexible and patient, and (4) “hold the line” to maintain the integrity of the research and the safety of human subjects. Conclusions: Criminologists have an obligation to provide the best possible evidence regarding the impact and consequences of criminal justice practices and programs. Experiments, considered by many to be the gold standard of empirical research methodologies, should be used whenever possible in order to fulfill this obligation.

Background: Depression often emerges for the first time during adolescence. There is accumulating evidence that universal depression prevention programs may have the capacity to reduce the impact of depression when delivered in the school environment. Objective: This trial investigated the effectiveness of SPARX-R, a gamified online cognitive behavior therapy intervention for the prevention of depression relative to an attention-matched control intervention delivered to students prior to facing a significant stressor-final secondary school exams. It was hypothesized that delivering a prevention intervention in advance of a stressor would reduce depressive symptoms relative to the control group. Methods: A cluster randomized controlled trial was conducted in 10 government schools in Sydney, Australia. Participants were 540 final year secondary students (mean 16.7 [SD 0.51] years), and clusters at the school level were randomly allocated to SPARX-R or the control intervention. Interventions were delivered weekly in 7 modules, each taking approximately 20 to 30 minutes to complete. The primary outcome was symptoms of depression as measured by the Major Depression Inventory. Intention-to-treat analyses were performed. Results: Compared to controls, participants in the SPARX-R condition (n=242) showed significantly reduced depression symptoms relative to the control (n=298) at post-intervention (Cohen d=0.29) and 6 months post-baseline (d=0.21) but not at 18 months post-baseline (d=0.33). Conclusions: This is the first trial to demonstrate a preventive effect on depressive symptoms prior to a significant and universal stressor in adolescents. It demonstrates that an online intervention delivered in advance of a stressful experience can reduce the impact of such an event on the potential development or exacerbation of depression.

Long Term Treatment

Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. The incidence of EoE has increased substantially over the past two decades in Europe and North America. The natural course of EoE appears to be progressive with a high risk of stricture formation. The current European guideline recommend swallowed topical corticosteroids, proton-pump inhibitors or dietary intervention for initial and long-term treatment of EoE. Swallowed topical corticosteroids can be considered to be the best studied drug class in EoE, with more than 1000 patients enrolled in randomized clinical trials worldwide. In most of them, fluticasone or budesonide formulations have been used that were originally designed for asthma therapy, thus presumably suboptimal for EoE treatment. The new orodispersible budesonide tablet with effervescent properties is the first approved esophageal-targeted formulation specifically developed for the treatment of EoE, which has become available in many European countries. This article gives an overview of the evolution of topical corticosteroids in EoE and provides an update on recent data from large-scale multicenter trials exploring the efficacy and safety of the orodispersible budesonide tablet with effervescent properties in adult EoE patients.

Abstract Objectives To determine the impact of two isocaloric diets containing (38% ,15% and 47% energy from fat, protein and carbohydrate, respectively): Western diet (WD) rich in saturated fat, refined carbohydrate, low in fiber and high in cholesterol, and a heart healthy diet (HHD) rich in unsaturated fat, unrefined carbohydrate, fruits/vegetables, high in fiber and low in cholesterol, on the composition and function of the gut microbiome Methods Thirty-Ossabaw pigs were fed WD or HHD diets with half within each group therapeutically treated with statin (atorvastatin [Lipitor]). The fecal microbiome was analyzed one and six months after dietary intervention by 16S rRNA sequencing and metagenomic function was empirically inferred Results Genus diversity was transiently affected with a reduced Shannon Diversity index one month after feeding the WD or HHD (FDR P < 0.05) with no change between groups at 6 months. Bacterial communities were clustered and separated by diet independent of gender and separated by treatment with statin in the HHD only. Verrucomicrobiaceae (Akkermansia) and Methanobacteriales (Methanobrevibacter) were increased in pigs as early as one month after feeding the HHD, as was Clostridiales and Bifidobacterium (associated with optimal intestinal health). There was an enrichment of Proteobacteria (Succinivibrionaceae, Desulfovibrionaceae) in pigs fed the WD. Additional members of the Firmicutes phylum were detected. Diet-dependent associations (all P < 0.05) were identified between Lachnospiraceae members and early host dyslipidemia, inflammation, and atheromatous lesions in the left anterior descending proximal (LAD) and LAD/Left circumflex (LCX) bifurcation six months post-intervention. Conclusions These data document for the first time a distinctive bacterial profile in Ossabaw pigs with a diet-induced dyslipidemia and early stage atherosclerosis. Taken together these results represent a new model to examine mechanistic pathways of dietary patterns and/or drug interactions and its effect on modulating microbiome in developing atherosclerosis.

The Impact

Depression cases have been reported among workers in the financial industries. Occupations in this industry are considered among the most stressful ones. This study aimed to examine the impact of depressive symptoms of financial workers in China on their productivity and well-being. A survey was conducted using a convenient sample of 1024 financial workers recruited from three large-scale financial organizations located in the north and south of China. The result of Hierarchical Regression Analyses shows that depressive symptoms of workers significantly impaired their work-life quality. Severity of depressive symptoms had significant positive relationships with three behavioral manifestations at works. These are, in order of decreasing effect size, turnover intention, presenteeism, and absenteeism. Specifically, depressive symptoms had a larger effect on presenteeism compared to absenteeism, which implies the unawareness or insufficient recognition of Chinese workers towards depression as an illness in comparison with other physical illnesses. Moreover, a Univariate Analysis was conducted to study the moderating effect of emotional labor on the relationship between the severity of depressive symptoms and presenteeism. An aggravating effect was found, displaying a greater damage of depressive symptoms to psychosocial functions of workers. Besides, depressive symptoms of workers also impaired their quality of life in aspects such as interpersonal relationships, life situation, and so on. This study provides evidence of impairments of depression in the workplace, urging the management to pay more attention to its employees' mental health no matter whether it is for the sake of the company's benefit or the employees' well-being.

ABSTRACTBackground: We developed an indicated preventive life-review course, “Looking for Meaning”, based on the assumption that reminiscence styles influence coping with depressive symptoms. This study describes the impact of this course in a pragmatic randomized controlled trial.Methods: Inclusion criteria were >50 years, a score of 5 or higher on the Center for Epidemiological Studies Depression Scale (CES-D), and no depressive disorder or psychotropic or psychological treatment. Participants were randomized and stratified by gender: the experimental group (N = 83) was offered the course and the comparison group (N = 88) a movie. There were three measurements: pre-treatment, post-treatment and 6 months after post-treatment. Depressive symptoms constituted the primary outcome. Secondary outcomes were anxiety symptoms, satisfaction with life, mastery and reminiscence styles. All analyses were conducted according to the intention-to-treat principle. Missing values were replaced by regression imputation.Results: The course reduced depressive symptoms, a decrease that was retained during follow-up. A significant between-group effect size was found (d = 0.58). There was also a reduction in symptoms of anxiety; however, the comparison group showed the same reduction, resulting in a small between-group effect size. Gender and level of depressive symptoms were found to be prognostic factors for the change in depressive symptoms; age was not. Post hoc analyses showed significant between-group effect sizes for females and those with a score above the cut-off of the CES-D.Conclusion: The course “Looking for Meaning” can be recommended for people aged over 50 years, females and older adults with a clinically relevant level of depressive symptoms (above cut-off) in particular.
