Intimate Partner Sexual Violence: An Exploratory Study on Sexual Victimization Profiles Among Survivors of Intimate Partner Violence in France

Intimate partner sexual violence (IPSV) is a common form of intimate partner violence (IPV). This study aimed to (a) identify a typology of intimate partner sexual victimization among French women victims of IPV on the basis of the frequency of various forms of sexual violence and (b) evaluate whether these profiles differ in several clinical characteristics. A total of 93 women consulting a specialized hospital service were recruited. Cluster analyses suggested four profiles: highly frequent rapes (5.4%), predominant sexual coercion (20.4%), medium frequency of all forms (20.4%), and low frequency of all forms (19.4%). Further person-centered research focusing on IPSV is warranted.

Intimate Partner Sexual Violence: A Phenomenological Interpretative Analysis Among Female Survivors in France

Despite its prevalence, intimate partner sexual violence (IPSV) remains a concealed and poorly understood form of violence against women. Although it is associated with numerous detrimental effects on mental health, very little is known about the subjective meaning of IPSV for survivors. This study addresses this gap by exploring IPSV from the perspective of female survivors within the context of their relationship with a male partner, using interpretative phenomenological analysis. This study seeks to provide a detailed examination of the personal experience of IPSV and to illuminate its meaning from a personal standpoint. We conducted in-depth interviews with seven IPSV survivors who were recruited after filing a complaint for intimate partner violence (IPV) in France. In total, five superordinate themes were identified: (a) "Setting the stage" describes how the complex dynamics preceding IPSV influence self-representation; (b) "Feeling like I'm nothing" describes the emotional experience of IPSV; (c) "Trying to get it, not getting it" describes how IPSV generates intense cognitive load; (d) "Looking back, developing a theory" describes how IPSV is interpreted retrospectively after breaking up with a violent partner; and (e) "Today: living with it" describes how IPSV affects the present. This study highlights how emotional distress and cognitive uncertainty are present on the way to IPSV, through IPSV, and even after filing charges and separating from the violent partner. Additionally, it shows that survivors attribute IPSV to a sense of individual vulnerability related to romantic love, hope, and traumatic childhood history. This study presents unique findings as it is the first one to explore the lived experience of IPSV among a sample of French IPV survivors.

Ptsd among a sample of french students: A misdiagnosed condition with many implications. preliminary results

Introduction

Students often suffer from stress, anxiety and depression (Saleh et al., 2019). However, research on PTSD is scarce among this population.

Objectives

We therefore wanted to explore the presence of PTSD and other psychopathological and psychological variables in this population.

Methods

We recruited 70 students -150 still planned- (22 years old, 70% women, 84.3% in the third year undergraduate) who filled out questionnaires at the university, after ethic committee’s approval.

Results

31.2% show PCL-5 scores in favor of a PTSD. The most frequently mentioned traumatic events (direct exposure) are physical assaults (49.3%), transport accidents (29.4%) and unwanted sexual experiences (23.2%). According to the Mann-Withney U test, if they do not differ from students without PTSD in the number of traumatic events encountered (LEC 5 ns), they show more stress, anxiety and depression (p <.02), more dissociative symptoms (p <.04), less social support available (p = .048), a gap between the importance given to studies as a value and action directed towards this value (p = .002), idem for leisure activities (p =.035), and more rumination (p <.001) and more experiential avoidance (p <. 001). These two latter appear to be powerful processes involved in PTSD, as the PCL5 score is 37% explained by avoidance and rumination, according to linear regression.

Conclusions

These preliminary results tend to show that PTSD should be investigated in students and seems to be linked to higher emotional difficulties, lower academic and social involvement. Rumination and avoidance could be an important therapeutic target.

Perceptions of the Post First-Lockdown Era in the Current Covid-19 Pandemic: Quantitative and Qualitative Survey of the French Population

Introduction: A pandemic with the severity of COVID-19 affects people's lives physically, as well as their daily routines, views of the world, and emotional balance. Lockdown is often an unpleasant experience due to a separation from loved ones, loss of freedom, and uncertainty over the disease status. To adjust, individuals and groups have had to adapt their perceptions of the event to the current scenario. This study aims to describe the perceptions of confined people on the changes occurring in their lives in the aftermath of the COVID-19 lockdown.

Methods: A total of 1,534 individuals (26.6% men; 73.4% women; mean age 41.6) responded to the questionnaire comprising 19 closed and five open-ended questions about the changes they anticipated in their lives in the immediate post-confinement era.

Results: Two definite groups appeared in the results: those who lived the confinement pleasantly, and those for which it was painful. They differ according to their confinement conditions and perceived degree of exposure to the virus. There seems to be a link for those who had a pleasant experience to a lower perceived exposure to the virus and less burdensome confinement conditions (young children, surface area, etc.). Lockdown conditions seem to influence the respondents' perceptions: a pleasant experience is associated with a vision of the society's evolution at large, and the care about its economic and professional progress; a painful one is associated more with focusing on the immediate needs of social support and personal well-being.

Discussion: Emotional experience during lockdown impacts the perception of its aftermath, with hope and anxiety becoming two ways of coping with uncertainty.

Differentiating unipolar and bipolar depression: Contribution of the Rorschach test (Comprehensive System)

OBJECTIVE

The aim of this study was to contribute to differential diagnoses of unipolar and bipolar depression using cognitive variables of the Rorschach test (Comprehensive System).

METHOD

One hundred forty one depressed inpatients (71 bipolar, 70 unipolar; mean age = 46, SD = 15.8; 64% women) previously evaluated and comparable regarding clinical characteristics of their illness (including current mood symptoms) were blindly tested using the Rorschach test (C.S.).

RESULTS

The cognitive profile of bipolar depressed patients was more impaired than the cognitive profile of unipolar depressed patients. Combining four cognitive specificities (tolerance to ambiguity, discrimination failure, difficulties in controlling ideational impulses, and impulsive or negligent processing) in a logistic regression model allows the identification of bipolarity with acceptable accuracy.

CONCLUSIONS

Some aspects of cognitive functioning, as assessed with the Rorschach test (CS), appear to be useful to capture some important cognitive specificities of bipolar depression and could contribute to differential diagnoses of mood disorders.

Relation between cognitive restraint and weight: Does a content validity problem lead to a wrong axis of care?

The aim of this research is to examine the relation between weight and cognitive restraint (CR), which is the intention to control food intake in order to maintain or lose weight, in a general French population sample. Is CR more prevalent in individuals with obesity than overweight, underweight or normal-weight subjects in this cross-sectional study? Are people affected by obesity non-restrained eaters? A total of 507 French people (80.2% women and 19.8% men), aged 18-78 years, responded to an online questionnaire. It appears that the most used questionnaire measuring CR has content validity problems as it seems to measure effective control and not the intention. Therefore, a numeric scale was used to answer the questions. Even if it is not possible in this study to test a causal link with latent variable modelling, our results seem to show that people with obesity more frequently intend to eat less or to eat healthier and/or to eat less sugar and fat than other people in order to control their weight. However, people affected by obesity do not succeed in so doing. These results raise the question of treatments advocating the increase of self-control. Finally, it would be necessary to obtain a real, scientific consensus on what CR is and on how to measure it in order to study the most effective treatments for people with overweight or obesity.

La remédiation cognitive dans le trouble bipolaire : une étude de cas

Introduction

Le trouble bipolaire est une maladie psychiatrique caractérisée par une alternance d’épisodes de dépression et/ou de manie, ainsi que de périodes de rémission plus ou moins partielles. Des études ont observé des déficits cognitifs chez les patients bipolaires, qui seraient présents dès le premier épisode et qui persisteraient tout au long de leur vie [4]. Ces troubles auraient un impact sur le fonctionnement psychosocial des patients [1]. Il n’existe actuellement aucune thérapie ciblant les déficits cognitifs des patients bipolaires. La remédiation cognitive est une thérapie permettant un entraînement des capacités cognitives et un apprentissage de stratégies de résolution de problèmes. Plusieurs études concluent à un effet bénéfique persistant de la thérapie chez les patients schizophrènes [3]. De nombreux auteurs suggèrent que la thérapie de remédiation cognitive pourrait également être bénéfique aux patients bipolaires [2].

Méthodologie

Notre étude a pour objectif d’observer l’intérêt que peut présenter la remédiation cognitive pour les patients bipolaires, à travers l’étude du parcours de Monsieur V., un patient bipolaire de type I, qui a suivi une thérapie individuelle de remédiation cognitive durant trois mois. Nous avons administré avant et après la thérapie un bilan clinique, un bilan neuropsychologique et le test de Rorschach.

Résultats

Les résultats indiquent une amélioration des capacités cognitives et fonctionnelles du patient. Nous avons observé des améliorations comportementales, mais également un changement plus profond dans la manière dont le patient mobilise des capacités cognitives.

Conclusion

Ces résultats suggèrent que des patients bipolaires pourraient bénéficier d’une thérapie de remédiation cognitive, et nécessiteraient d’être reproduits sur une plus large population.

Prefrontal cortex dysfunction in patients with suicidal behavior

BACKGROUND

Abnormal serotonergic neurotransmission has long been demonstrated in suicidal behavior. The dorsal and median raphe nuclei housing the main serotonergic cell bodies and the prefrontal cortex (PFC), particularly the ventral part innervated by the serotonergic system, have therefore been studied extensively in suicidal behavior research. However, only a few studies have described neuropsychological function impairment in suicidal patients. We investigated PFC-related neuropsychological function in patients with suicidal behavior, separating dorsolateral PFC (DLPFC)- and orbitofrontal cortex (OFC)-related functions.

METHOD

We compared 30 euthymic patients with suicidal behavior aged 18-65 years with 39 control subjects, for the following neuropsychological domains: global intellectual functioning, reward sensitivity, initiation, inhibition, and working memory. Patients and controls were compared by means of univariate and multivariate analyses, adjusting for age at interview, level of education and mood state at the time of evaluation. Trait impulsivity, measured with the Barratt Impulsivity Scale version 10 (BIS-10), was also included as a covariate in a subset of analyses.

RESULTS

Multivariate comparisons demonstrated significant executive function deficits in patients with suicidal behavior. In particular, we observed impairment in visuospatial conceptualization (p<0.0001), spatial working memory (p=0.001), inhibition (Hayling B-A, p=0.04; go anticipations, p=0.01) and visual attention (or reading fluency) (p=0.002). Similar results were obtained following adjustment for motor impulsivity as a covariate, except for spatial working memory.

CONCLUSIONS

These deficits are consistent with prefrontal dysfunction in patients with suicidal behavior. Differentiation between DLPFC- and OFC-related neuropsychological functions showed no specific dysfunction of the orbitofrontal region in patients with suicidal behavior in our sample.

Soybean beta-conglycinin alpha subunit is phosphorylated on two distinct serines by protein kinase CK2 in vitro

Protein kinase CK2 purified from the yeast Yarrowia lipolytica was used to phosphorylate soybean beta-conglycinin alpha subunit. CK2 is known to phosphorylate serines and threonines in the consensus sequence Ser/Thr-X-X-Glu/Asp/SerP/TyrP. Beta-conglycinin alpha subunit (68 kDa) presents seven consensus sequences, but only 0.5-1 mol P/mol alpha subunit was incorporated by CK2. [32P]Phosphorylated beta-conglycinin alpha subunit was cleaved either by cyanogen bromide or by trypsin. 32P was incorporated into the largest cyanogen bromide fragment only (50 kDa, N-terminal) and only two radiolabeled zones were detected after HPLC of the trypsic digest. The corresponding phosphorylated zones were collected and further analyzed by RP-HPLC coupled to electrospray ionization mass spectrometry (LC-ESMS). Two phosphorylated sites, Ser 75 and Ser 117, were determined after MS-MS analysis of three phosphopeptides identified as 70-89, 116-126, and 116-127 sequences. Over the seven consensus sequences of beta-conglycinin alpha subunit, Ser 75 is the only one which was phosphorylated. Ser 117 was phosphorylated although it is not an expected phosphorylation site according to the canonical consensus sequence criteria as there is no acidic determinant at the +3 position. Both Ser 75 and Ser 117 are located inside very acidic sequences, by contrast with the other unphosphorylated potential sites.

Enzymatic phosphorylation of food proteins by purified and recombinant protein kinase CK2

Protein kinase CK2 formerly called casein kinase II is a protein kinase able to phosphorylate more than 100 proteic substrates. We have purified protein kinase CK2 from the yeast Y. lipolytica to phosphorylate milk and plant reserve proteins to a significant extent. In the case of plant reserve proteins, which are polymeric substrates, not all subunits are substrate for protein kinase CK2, even if non phosphorylated subunits contain significant potent phosphorylations sites. Best substrates were soy beta-conglycinin (0.72 P/mol) and dephosphorylated caseins (0.5 P/mol). We have studied some functional properties of phosphorylated caseins. Solubility was improved for all pH values but pI. Sensitivity to calcium has also been assessed, and it is slightly improved upon phosphorylation. We have cloned the catalytic subunit of protein kinase CK2 from yeast Y. lipolytica. The recombinant catalytic subunit expressed in E. coli was active and displayed kinetic properties similar to those of the purified enzyme. The recombinant catalytic subunit was able to phosphorylate plant reserve proteins and milk proteins to a significant extent. Best substrates were soy beta-conglycinin (1.0 P/mol), and glycinin (0.59 P/mol).

Enzymatic phosphorylation of soy globulins by the protein kinase CK2. Determination of the phosphorylation sites of beta-conglycinin alpha subunit by mass spectrometry

Beta-conglycinin alpha subunit has been phosphorylated using a cAMP-independent protein kinase (CK2) purified from the yeast Yarrowia lipolytica. CK2 is known to phosphorylate serines and threonines in the consensus sequence Ser/Thr-X-X-Asp/Glu. Only 0.5 to 1 mol P/mol alpha subunit was incorporated although seven consensus sequences are present. Phosphorylated beta-conglycinin alpha subunit (P-alpha) was digested by trypsin. The resulting peptides were analysed by RP-HPLC coupled to electrospray ionisation mass spectrometry (LC-ESMS). Two phosphopeptides were identified corresponding to 70-89 and 116-127 sequences with Ser 75 and Ser 117 phosphorylated respectively. Ser 75 is one of the predicted phosphorylation sites according to the consensus sequence criteria. Ser 117 is inside a very acidic peptide but does not belong to a previously described consensus sequence.
