ABSTRACT

Objectives: Personality organization or functioning describes biographically acquired characteristics for the regulation of psychological processes. Limitations correlate with symptom load. This study examines whether significant improvement in personality functioning can be achieved in the framework of a multimodal psychodynamic treatment and its influence on the psychological symptoms. Methods: In this naturalistic study design (N = 318) personality organization was measured with the OPD-SQS and the symptoms were obtained using PHQ-9, GAD-7, SCL-9 and mini- Spin. Changes in the functioning levels were calculated using a t-test. The associations between the functional and symptom improvements were calculated using hierarchical regressionmodels. ANOVAs for dependent samples were used to calculate the association of the personality organization changes on symptom reduction Results: Treatment resulted in significant improvement in personality structure.The greater the changes, the lower the symptom burden at the end of treatment. Patients with lower personality structure benefited equally well from treatment. Conclusions: Personality functioning improves with multimodal psychodynamic therapy and is accompanied by reduction of psychological symptoms. Structural changes proceed equally in high and low structured patients.

ABSTRACT

BACKGROUND: Our learning about human reproductive development is greatly hampered due to the absence of an adequate model. Animal studies cannot truthfully recapitulate human developmental processes, and studies of human fetal tissues are limited by their availability and ethical restrictions. Innovative three-dimensional (3D) organoid technology utilizing human pluripotent stem cells (hPSCs) offered a new approach to study tissue and organ development in vitro. However, a system for modeling human gonad development has not been established, thus, limiting our ability to study causes of infertility. METHODS: In our study we utilized the 3D hPSC organoid culture in mini-spin bioreactors. Relying on intrinsic self-organizing and differentiation capabilities of stem cells, we explored whether organoids could mimic the development of human embryonic and fetal gonad. RESULTS: We have developed a simple, bioreactor-based organoid system for modeling early human gonad development. Male hPSC-derived organoids follow the embryonic gonad developmental trajectory and differentiate into multipotent progenitors, which further specialize into testicular supporting and interstitial cells. We demonstrated functional activity of the generated cell types by analyzing the expression of cell type-specific markers. Furthermore, the specification of gonadal progenitors in organoid culture was accompanied by the characteristic architectural tissue organization. CONCLUSION: This organoid system opens the opportunity for detailed studies of human gonad and germ cell development that can advance our understanding of sex development disorders. Implementation of human gonad organoid technology could be extended to modeling causes of infertility and regenerative medicine applications.

ABSTRACT

BACKGROUND: Human testicular cells are greatly valuable to the research community as tools for studying testicular physiology and the effects of environmental pollutants. Because adult testicular cells have a limited self-organization capacity and life span, we investigated whether human pluripotent stem cells (hPSCs) can be used together with testicular cells to move a step closer toward making an optimal model of the human testis. METHODS: We used in vitro culture of donor testicular cells under serum-containing and chemically defined conditions. CRISPR-Cas9 technology was applied to introduce fluorescent transgenes (mCherry2 and EGFP) into hPSCs and testicular cells. hPSC-derived spheroids were co-cultured with human testicular cells in mini-spin bioreactors. RESULTS: Traditional cell culture conditions used for maintenance of testicular somatic cells generally contain serum and pose limitations on evaluating the role of active molecules on cell functions. We established that chemically defined culture conditions can be used to maintain testicular cells without the loss of proliferative activity. These cultures demonstrate marker expression which is characteristic of common testicular cell types: Sertoli, Leydig, endothelial, myoid cells, and macrophages. In order to model testicular physiology, it is important to be able to perform live cell microscopy. Thus, we generated fluorescent protein-expressing human testicular cells and hPSCs and demonstrated that these cell types can be successfully co-cultured for prolonged periods of time in a three-dimensional microenvironment. CONCLUSION: Our research extends the possible applications of human testis-derived somatic cells and shows that they can be used together with hPSCs for further studies of human male reproductive biology.

ABSTRACT

Social anxiety is common in the general population, as well as among students in higher education. For screening of social anxiety, there is a need for brief scales. In the present study, the psychometric properties were examined in a Swedish version of the Social Phobia Inventory (SPIN) and the Mini-Social Phobia Inventory (Mini-SPIN) in a university student sample ( n = 161). In addition to the SPIN and Mini-SPIN, participants completed measures of fear of public speaking, general anxiety, depression, and quality of life. Exploratory factor analyses were used to investigate the underlying dimensions of the SPIN, and reliability, convergent, and divergent validity of SPIN and Mini-SPIN were examined by Cronbach's alpha and correlation analyses. It was found that a shorter eight-item version of the SPIN was associated with two solid factors ( fear and avoidance of social interaction and fear and avoidance of criticism), and acceptable internal consistency, convergent, and divergent validity. In addition, the Mini-SPIN was associated with satisfactory convergent validity, but the reliability was not acceptable. It is concluded that the SPIN-8 is a viable screening tool for social anxiety in a university student population.

ABSTRACT

Although depression and anxiety are the most common comorbidities in individuals with Autism Spectrum Disorder (ASD), descriptive data for their prevalence among autistic adults are limited. This study provides descriptive data for a cohort of 155 autistic adults (mean age = 27.1 years, SD = 11.9) of average IQ on the short-form version of the Depression Anxiety Stress Scales and the Mini Social Phobia Inventory. Also included were 79 non-ASD participants (mean age = 26.2, SD = 10.2) who completed the mini-SPIN. A substantial percentage (39-46%) of autistic adults scored within the 'Moderate' to 'Extremely Severe' range on the DASS-21. The DASS-21 would be a valuable rapid screening device for these comorbid conditions in autistic adults.

ABSTRACT

BACKGROUND: A short screening for social anxiety disorder is useful in clinical and epidemiological contexts. However, the German version of the short form of the Social Phobia Inventory (mini-SPIN) has not been evaluated yet. Therefore, our aim was to determine reliability, validity and population based norms of the German mini-SPIN. METHODS: The mini-SPIN was evaluated in a clinical (N = 1254) and in a representative community sample (N = 1274). Clinical diagnoses, the Patient Health Questionnaire depression (PHQ-9) and somatization modules (PHQ-15), the Generalized Anxiety Disorder Scale (GAD-7), the Liebowitz Social Anxiety Scale (LSAS), and the Short-Form-12 Health Survey (SF-12) were used in the clinical sample. In the community sample, participants filled out socio-demographic and health related questions and short versions of the PHQ (PHQ-2, GAD-2, panic item). Internal consistency, test-retest reliability, sensitivity to change, discriminant validity, and convergent validity were examined. Receiver operating characteristic curve analyses were performed to determine cut-off scores. Population based norms were computed from the community sample. RESULTS: We found internal consistencies between 0.80 and 0.83. Test-retest correlation was Rho = 0.61; sensitivity to change was comparable to the LSAS. Correlations indicated good convergent and discriminant validity of the mini-SPIN. Strict measurement invariance can be assumed regarding age and gender. Receiver operating characteristic curve analysis suggested a cut-off of 6 or higher for a probable diagnosis of SAD. CONCLUSIONS: The German version of the mini-SPIN is a reliable and valid instrument. Its brevity makes it valuable for screening and assessing changes of social anxiety in clinical and epidemiological studies.

ABSTRACT

A fobia social (também conhecida como transtorno de ansiedade social) é um grave transtorno mental que traz sofrimento e incapacitação. O objetivo deste estudo foi validar para a língua portuguesa o Mini-Inventário de Fobia Social (Mini-SPIN) em uma amostra da população. Foi realizado um estudo da validade discriminativa do Mini-SPIN em uma amostra de 644 pessoas (grupo positivo para o Mini-SPIN: n = 218 e grupo controle/negativo: n = 426) de um estudo de prevalência de transtornos de ansiedade na cidade de Santo André (SP). A versão em português do Mini-SPIN (com escore de 6 pontos, sugerido na versão original em inglês) demonstrou uma sensibilidade de 95,0 por cento, especificidade de 80,3 por cento, valor preditivo positivo de 52,8 por cento, valor preditivo negativo de 98,6 por cento e taxa de classificação incorreta de 16,9 por cento. Com escores de 7 pontos, foi observado um aumento na especificidade e no valor preditivo positivo (88,6 por cento e 62,7 por cento), sendo que a sensibilidade e o valor preditivo negativo (84,8 por cento e 96,2 por cento) mantiveram-se altos. A versão em português do Mini-SPIN apresentou qualidades psicométricas satisfatórias em termos de validade discriminativa. Neste estudo, o ponto de corte igual a 7 mostrou-se mais adequado para a identificação da fobia social generalizada.


Social phobia (also known as social anxiety disorder) is a severe mental disorder that brings distress and disability. The aim of this study was validate to the Portuguese language the Mini-Social Phobia Inventory (Mini-SPIN) in a populational sample. We performed a discriminative validity study of the Mini-SPIN in a sample of 644 subjects (Mini-SPIN positive group: n = 218 and control/negative group: n = 426) of a study of anxiety disorders' prevalence in the city of Santo André-SP. The Portuguese version of the Mini-SPIN (with score of 6 points, suggested in the original English version) demonstrated a sensitivity of 95.0 percent, specificity of 80.3 percent, positive predictive value of 52.8 percent, negative predictive value of 98.6 percent and incorrect classification rate of 16.9 percent. With score of 7 points, was observed an increase in the specificity and positive predictive value (88.6 percent and 62.7 percent), while the sensitivity and negative predictive value (84.8 percent and 96.2 percent) remained high. The Portuguese version of the Mini-SPIN showed satisfactory psychometric qualities in terms of discriminative validity. In this study, the cut-off of 7, was considered to be the most suitable to screening of the generalized social phobia.
