OBJECTIVE: Depth of emotional processing has shown to be related to outcome across approaches to psychotherapy. Moreover, a specific emotional sequence has been postulated and tested in several studies on experiential psychotherapy (Pascual-Leone & Greenberg, 2007). This process-outcome study aims at reproducing the sequential model of emotional processing in psychodynamic psychotherapy for adjustment disorder and linking these variables with ultimate therapeutic outcome. METHOD: In this study, 32 patients underwent short-term dynamic psychotherapy. On the basis of reliable clinical change statistics, a subgroup (n = 16) presented with good outcome and another subgroup (n = 16) had a poor outcome in the end of treatment. The strongest alliance session of each case was rated using the observer-rated system Classification of Affective Meaning States. Reliability coefficients for the measure were excellent (κ = .82). RESULTS: Using 1 min as the fine-grained unit of analysis, results showed that the experience of fundamentally adaptive grief was more common in the in-session process of patients with good outcome, compared with those with poor outcomes (χ2 = 6.56, p = .01, d = 1.23). This variable alone predicted 19% of the change in depressive symptoms as measured by the Beck Depression Inventory at the end of treatment. Moreover, sequences of the original model were supported and related to outcome. CONCLUSIONS: These results are discussed within the framework of the sequential model of emotional processing and its possible relevance for psychodynamic psychotherapy.

A long term study on the reproductive strategies of Formica lugubris (Formica rufa group) has revealed many new important facts. Within a supercolony the sex-ratio is strongly female biased. Some of the sexuals mate on the nest surface, whereas others fly from the nest. Those sexuals participating in flights aggregate in particular meadow sites (mating places). On these places females attract males by releasing a sex pheromone.

Autism spectrum disorder (ASD) symptoms frequently occur in subjects with attention deficit/hyperactivity disorder (ADHD). While there is evidence that both ADHD and ASD have differential structural correlates, no study to date has investigated these structural correlates within a framework that robustly accounts for the phenotypic overlap between the two disorders. The presence of ASD symptoms was measured by the parent-reported Children's Social and Behavioural Questionnaire (CSBQ) in ADHD subjects (n = 180), their unaffected siblings (n = 118) and healthy controls (n = 146). ADHD symptoms were assessed by a structured interview (K-SADS-PL) and the Conners' ADHD questionnaires. Whole brain T1-weighted MPRAGE images were acquired and the structural MRI correlates of ASD symptom scores were analysed by modelling ASD symptom scores against white matter (WM) and grey matter (GM) volumes using mixed effects models which controlled for ADHD symptom levels. ASD symptoms were significantly elevated in ADHD subjects relative to both controls and unaffected siblings. ASD scores were predicted by the interaction between WM and GM volumes. Increasing ASD score was associated with greater GM volume. Equivocal results from previous structural studies in ADHD and ASD may be due to the fact that comorbidity has not been taken into account in studies to date. The current findings stress the need to account for issues of ASD comorbidity in ADHD.

INTRODUCTION: We present the case of a patient with a cobalamin deficiency resulting in pancytopaenia, emphasizing the importance to define, diagnose and treat cobalamin deficiency. CASE PRESENTATION: A 52-year-old man from the Democratic Republic of Congo presented to the emergency department with shortness of breath and a sore tongue. Physical examination was unremarkable. His haemoglobin was low and the peripheral blood smear revealed pancytopaenia with a thrombotic microangiopathy. The findings were low cobalamin and folate levels, and high homocysteine and methylmalonate levels. Pernicious anaemia with chronic atrophic gastritis was confirmed by gastric biopsy and positive antiparietal cell and anti-intrinsic factor antibodies. Cobalamin with added folate was given. Six months later, the patient was asymptomatic. CONCLUSION: Cobalamin deficiency should always be ruled out in a patient with pancytopaenia. Our case report highlights a life-threatening cobalamin deficiency completely reversible after treatment.

Use of assisted reproductive technology (ART) is increasing in many developed countries. Arterial and venous thromboembolic complications are reported during ART with an incidence of 0.1%. The development of these events has been mainly ascribed to the presence of ovarian hyperstimulation syndrome (OHSS). Precise mechanisms by which OHSS and exogenous hormonal stimulation used in ART induce thromboembolic events remain unclear. However, vascular endothelial growth factor secreted during OHSS, high estradiol concentrations, and blood hyperviscosity play a major role in inducing a prothrombotic state. Therefore, before planning an ART, individual thromboembolic risk should be assessed and thromboprophylaxis offered to high risk patients. Prophylaxis should be initiated in women who develop moderate-to-severe OHSS.

There is evidence that obesity-related disorders are increased among people with depression. Variation in the FTO (fat mass and obesity associated) gene has been shown to contribute to common forms of human obesity. This study aimed to investigate the genetic influence of polymorphisms in FTO in relation to body mass index (BMI) in two independent samples of major depressive disorder (MDD) cases and controls. We analysed 88 polymorphisms in the FTO gene in a clinically ascertained sample of 2442 MDD cases and 809 controls (Radiant Study). In all, 8 of the top 10 single-nucleotide polymorphisms (SNPs) showing the strongest associations with BMI were followed-up in a population-based cohort (PsyCoLaus Study) consisting of 1292 depression cases and 1690 controls. Linear regression analyses of the FTO variants and BMI yielded 10 SNPs significantly associated with increased BMI in the depressive group but not the control group in the Radiant sample. The same pattern was found in the PsyCoLaus sample. We found a significant interaction between genotype and affected status in relation to BMI for seven SNPs in Radiant (P<0.0057), with PsyCoLaus giving supportive evidence for five SNPs (P-values between 0.03 and 0.06), which increased in significance when the data were combined in a meta-analysis. This is the first study investigating FTO and BMI within the context of MDD, and the results indicate that having a history of depression moderates the effect of FTO on BMI. This finding suggests that FTO is involved in the mechanism underlying the association between mood disorders and obesity.

BACKGROUND: Assisted reproductive technology (ART) involves the manipulation of early embryos at a time when they may be particularly vulnerable to external disturbances. Environmental influences during the embryonic and fetal development influence the individual's susceptibility to cardiovascular disease, raising concerns about the potential consequences of ART on the long-term health of the offspring. METHODS AND RESULTS: We assessed systemic (flow-mediated dilation of the brachial artery, pulse-wave velocity, and carotid intima-media thickness) and pulmonary (pulmonary artery pressure at high altitude by Doppler echocardiography) vascular function in 65 healthy children born after ART and 57 control children. Flow-mediated dilation of the brachial artery was 25% smaller in ART than in control children (6.7±1.6% versus 8.6±1.7%; P<0.0001), whereas endothelium-independent vasodilation was similar in the 2 groups. Carotid-femoral pulse-wave velocity was significantly (P<0.001) faster and carotid intima-media thickness was significantly (P<0.0001) greater in children conceived by ART than in control children. The systolic pulmonary artery pressure at high altitude (3450 m) was 30% higher (P<0.001) in ART than in control children. Vascular function was normal in children conceived naturally during hormonal stimulation of ovulation and in siblings of ART children who were conceived naturally. CONCLUSIONS: Healthy children conceived by ART display generalized vascular dysfunction. This problem does not appear to be related to parental factors but to the ART procedure itself.

To explore possible morphological abnormalities in the dorsal and subgenual parts of anterior cingulate cortex in mood disorders and schizophrenia, we performed a quantitative postmortem study of 44 schizophrenic patients, 21 patients with sporadic bipolar disorder, 20 patients with sporadic major depression, and 55 age- and sex-matched control cases. All individuals were drug naïve or had received psychotropic medication for less than 6 months, and had no history of substance abuse. Neuron densities and size were estimated on cresyl violet-stained sections using a stereological counting approach. The distribution and density of microtubule-associated (MAP2, MAP1b) and tau proteins were assessed by immunocytochemistry and quantitative immunodot assay. Mean total and laminar cortical thicknesses as well as mean pyramidal neuron size were significantly decreased in the dorsal and subgenual parts of areas 24 (24sg) in schizophrenic cases. Patients with bipolar disorder showed a substantial decrease in laminar thickness and neuron densities in layers III, V, and VI of the subgenual part of area 24, whereas patients with major depression were comparable to controls. Immunodot assay showed a significant decrease of both MAP2 and MAP1b proteins in bipolar patients but not in patients with schizophrenia and major depression. The neuroanatomical and functional significance of these findings are discussed in the light of current hypotheses regarding the role of areas 24 and 24sg in schizophrenia and bipolar disorder.

Male dominance hierarchies are usually linked to relative body size and to weapon size, that is, to determinants of fighting ability. Secondary sexual characters that are not directly used as weapons could still be linked to dominance if they reveal determination or overall health and vigour and hence, indirectly, fighting ability. We studied the mating behaviour of the minnow, Phoxinus phoxinus, a cyprinid fish in which males develop breeding tubercles during the spawning season. The function of these breeding tubercles is still not clear. Using microsatellite markers, we determined male reproductive success under controlled conditions. The minnows were territorial and quickly established a dominance hierarchy at the beginning of the spawning season. Dominance was strongly and positively linked to fertilization success. Although body size and number of breeding tubercles were not significantly correlated in our sample, both large males and males with many breeding tubercles were more dominant and achieved higher fertilization success than small males or males with few tubercles. We found multimale fertilization in most clutches, suggesting that sperm competition is important in this species. Females showed behaviour that may be linked to spawning decision, that is, male dominance might not be the only determinant of male reproductive success in minnows

BACKGROUND AND AIMS: Previous studies suggest that the new DSM-5 criteria for alcohol use disorder (AUD) will increase the apparent prevalence of AUD. This study estimates the 12-month prevalence of AUD using both DSM-IV and DSM-5 criteria and compares the characteristics of men in a high risk sample who meet both, only one and neither sets of diagnostic criteria. DESIGN, SETTING AND PARTICIPANTS: 5943 Swiss men aged 18-25 years who participated in the Cohort Study on Substance Use Risk Factors (C-SURF), a population-based cohort study recruited from three of the six military recruitment centres in Switzerland (response rate = 79.2%). MEASUREMENTS: DSM-IV and DSM-5 criteria, alcohol use patterns, and other substance use were assessed. FINDINGS: Approximately 31.7% (30.5-32.8) of individuals met DSM-5 AUD criteria [21.2% mild (20.1-22.2); 10.5% moderate/severe (9.7-11.3)], which was less than the total rate when DSM-IV criteria for alcohol abuse (AA) and alcohol dependence (AD) were combined [36.8% overall (35.5-37.9); 26.6% AA (25.4-27.7); 10.2% AD (9.4-10.9)]. Of 2479 respondents meeting criteria for either diagnoses, 1585 (63.9%) met criteria for both. For those meeting DSM-IV criteria only (n = 598, 24.1%), hazardous use was most prevalent, whereas the criteria larger/longer use than intended and tolerance to alcohol were most prevalent for respondents meeting DSM-5 criteria only (n = 296, 11.9%). Two in five DSM-IV alcohol abuse cases and one-third of DSM-5 mild AUD individuals fulfilled the diagnostic criteria due to the hazardous use criterion. The addition of the craving and excluding of legal criterion, respectively, did not affect estimated AUD prevalence. CONCLUSIONS: In a high-risk sample of young Swiss males, prevalence of alcohol use disorder as diagnosed by DSM-5 was slightly lower than prevalence of DSM-IV diagnosis of dependence plus abuse; 63.9% of those who met either criterion met criteria for both.

Measurements of magnetic hysteresis loops in Cu-Al-Mn alloys of different Mn content at low temperatures are presented. The loops are smooth and continuous above a certain temperature, but exhibit a magnetization discontinuity below that temperature. Scaling analysis suggest that this system displays a disorder-induced phase transition line. Measurements allow one to determine the critical exponents ß=0.03±0.01 and ß¿=0.4±0.1, which coincide with those reported recently in a different system, thus supporting the existence of universality for disorder-induced critical points.

The relative number of workers and female sexuals fathered by two males mated with a queen were directly assessed using microsatellite and allozyme markers in field colonies of the ants Formica exsecta and F. truncorum. In both species one of the two males consistently fathered more offspring than the other. There was, however, no evidence that one male might be particularly successful in fathering a disproportionally high proportion of female sexuals relative to the proportion of workers. Moreover, in F. exsecta, the proportions of worker pupae and worker adults fathered by each male did not differ significantly between cohorts. The most likely explanation for this pattern is that females store different amounts of sperm from the two males they mated with.
