Achievement emotions that the university student experiences in the learning process
can be significant in facilitating or interfering with learning. The present research looked for linear
and predictive relations between university students¿ achievement emotions, coping strategies, and
engagement-burnout, in three dierent learning situations (classroom, study time, and testing).
Hypotheses were identified for a possible model that would analyze the two facets of perfectionism
based on these relations. In the case of perfectionistic strivings, the test hypothesis was that positive
emotions would predispose the use of problem-focused coping strategies and an emotional state of
engagement; in the case of perfectionistic concerns, however, negative emotions would predispose
the use of emotion-focused strategies and a state of burnout. A total of 654 university students
participated in the study, using an online tool to complete validated questionnaires on the three study
variables. All students provided informed consent and corresponding permissions. Given the ex-post
facto linear design, the predictions could be verified for each situation by means of logistic regression
analyses and Structural Equations Models (SEM). Empirical results lent support, in varying degree,
to the proposed theoretical relations. The testing situation was of particular interest. We discuss
implications for perfectionism research and for the practice of prevention, education and health care
in the university setting.

Introduction: Major depressive disorder (MDD) patients experience a systemic inflammatory stage. Monocytes play an important role in innate inflammatory responses and may be modulated by bacterial translocation. Our aim was to investigate the subset distribution and function of circulating monocytes, levels of proinflammatory cytokines, gut barrier damage, and bacterial translocation in MDD patients. Methods: Twenty-two MDD patients without concomitant diseases and 14 sex- and age-matched healthy controls were studied. The levels of circulating CD14(++)CD16(-) (classical), CD14(++)CD16(++) (intermediate) and CD14(-)CD16(++) (nonclassical) monocytes and the intracytoplasmic tumor necrosis factor (TNF)-alpha, interleukin (IL)-1 beta, IL-6, and IL-10 expression in the presence or absence of lipopolysaccharide (LPS) stimulation were analyzed by polychromatic flow cytometry. The serum TNF-alpha, IL-1 beta, IL-6, and IL-10 levels were measured by Luminex. LPS-binding protein (LBP), intestinal fatty acid-binding protein (I-FABP), and zonulin were measured by enzyme-linked immunosorbent assay (ELISA). Results: MDD patients had a significant increase in the frequency of intermediate monocytes and a significant decrease in the frequency of classical monocytes compared to those in the healthy controls. MDD patients had a significantly increased percentage of classical monocytes that expressed IL-1 beta, intermediate monocytes that expressed IL-1 beta and IL6 and nonclassical monocytes that expressed IL-1 beta, and decreased levels of nonclassical monocytes that expressed IL6 compared to those in the healthy controls. MDD patients had significantly increased levels of circulating TNF-alpha, IL-1 beta, LBP, and I-FABP compared to those in the healthy controls. MDD patients with high LBP levels had a significant reduction in the number of circulating monocytes compared to that in the normal-LBP MDD patients, which can be mainly ascribed to a decrease in the number of intermediate and nonclassical monocytes. Conclusions: We have demonstrated that compared to the healthy controls, MDD patients show a marked alteration in circulating monocytes, with an expansion of the intermediate subset with increased frequency of IL-1 beta and IL-6 producing cells. These patients also exhibited a systemic proinflammatory state, which was characterized by the enhanced serum TNF-alpha and IL-1 beta levels compared to those in the healthy controls. Furthermore, MDD patients showed increased LBP and I-FABP levels compared to those in healthy controls, indicating increased bacterial translocation and gut barrier damage.

Timing and other cognitive processes demanding cognitive control become interlinked when there is an increase in the level of difficulty or effort required. Both functions are interrelated and share neuroanatomical bases. A previous meta-analysis of neuroimaging studies found that people with schizophrenia had significantly lower activation, relative to normal controls, of most right hemisphere regions of the time circuit. This finding suggests that a pattern of disconnectivity of this circuit, particularly in the supplementary motor area, is a trait of this mental disease. We hypothesize that a dysfunctional temporal/cognitive control network underlies both cognitive and psychiatric symptoms of schizophrenia and that timing dysfunction is at the root of the cognitive deficits observed. The goal of our study was to look, in schizophrenia patients, for brain structures activated both by execution of cognitive tasks requiring increased effort and by performance of time perception tasks. We conducted a signed differential mapping (SDM) meta-analysis of functional neuroimaging studies in schizophrenia patients assessing the brain response to increasing levels of cognitive difficulty. Then, we performed a multimodal meta-analysis to identify common brain regions in the findings of that SDM meta-analysis and our previously-published activation likelihood estimate (ALE) meta-analysis of neuroimaging of time perception in schizophrenia patients. The current study supports the hypothe

BACKGROUND:
The association between body mass index (BMI) and depression is complex and controversial. The present study examined the relationship between BMI and new-onset depression during 7 years of follow-up in 20,212 adult women attending Primary Health Care Centres in Navarra, Spain.
METHODS:
The Atención Primaria de Navarra (APNA) study is a dynamic prospective cohort study. A total of 20,212 women aged 18-99 years (mean age: 50.7±18.5 years) without depression at baseline were selected from 2004 to 2011. We estimated the incidence of depression. We used the Kaplan-Meier analysis to predict the survival curve. The risk of depression onset according to different measures of BMI at baseline was assessed using Cox regression analyses.
RESULTS:
During the 7 years of follow-up, depression appeared in 8.9% (95% CI 8.5-9.3). The highest rates of depression incidence at follow-up occurred in underweight and obese women (9.8% [95% CI 7.3-12.9] and 10.3% [95% CI 9.5-11.1] respectively). The distribution of depression incidence by weight category was U-shaped. The risk of depression increased over time with an observed Kaplan-Meier estimation of 6.67. After adjusting for age, underweight and obese women at baseline have increased risk of depression onset during the follow-up period compared with normal weight women (HR=1.48, 95% CI=1.09-2.00 and HR=1.14, 95% CI=1.01-1.29 respectively).
CONCLUSIONS:
In this 7-year prospective study in the APNA women population, depression emerged in 8.9%. Being underweight or obese (not overweight) at baseline is significantly associated with future onset of depression.
