Interpersonal sensitivity and persistent attenuated psychotic symptoms in adolescence.

Interpersonal sensitivity defines feelings of inner-fragility in the presence of others due to the expectation of criticism or rejection. Interpersonal sensitivity was found to be related to attenuated positive psychotic symptom during the prodromal phase of psychosis. The aims of this study were to examine if high level of interpersonal sensitivity at baseline are associated with the persistence of attenuated positive psychotic symptoms and general psychopathology at 18-month follow-up. A sample of 85 help-seeking individuals (mean age = 16.6, SD = 5.05) referred an Italian early detection project, completed the interpersonal sensitivity measure and the structured interview for prodromal symptoms (SIPS) at baseline and were assessed at 18-month follow-up using the SIPS. Results showed that individuals with high level of interpersonal sensitivity at baseline reported high level of attenuated positive psychotic symptoms (i.e., unusual thought content) and general symptoms (i.e., depression, irritability and low tolerance to daily stress) at follow-up. This study suggests that being "hypersensitive" to interpersonal interactions is a psychological feature associated with attenuated positive psychotic symptoms and general symptoms, such as depression and irritability, at 18-month follow-up. Assessing and treating inner-self fragilities may be an important step of early detection program to avoid the persistence of subtle but very distressing long-terms symptoms.

Interpersonal sensitivity and functioning impairment in youth at ultra-high risk for psychosis.

A personality trait that often elicits poor and uneasy interpersonal relationships is interpersonal sensitivity. The aim of the present study was to explore the relationship between interpersonal sensitivity and psychosocial functioning in individuals at ultra-high risk for psychosis as compared to help-seeking individuals who screened negative for an ultra-high risk of psychosis. A total sample of 147 adolescents and young adult who were help seeking for emerging mental health problems participated in the study. The sample was divided into two groups: 39 individuals who met criteria for an ultra-high-risk mental state (UHR), and 108 (NS). The whole sample completed the Interpersonal Sensitivity Measure (IPSM) and the Global Functioning: Social and Role Scale (GF:SS; GF:RS). Mediation analysis was used to explore whether attenuated negative symptoms mediated the relationship between interpersonal sensitivity and social functioning. Individuals with UHR state showed higher IPSM scores and lower GF:SS and GF:RS scores than NS participants. A statistically negative significant correlation between two IPSM subscales (Interpersonal Awareness and Timidity) and GF:SS was found in both groups. Our results also suggest that the relationship between the aforementioned aspects of interpersonal sensitivity and social functioning was not mediated by negative prodromal symptoms. This study suggests that some aspects of interpersonal sensitivity were associated with low level of social functioning. Assessing and treating interpersonal sensitivity may be a promising therapeutic target to improve social functioning in young help-seeking individuals.

Psychological distress and coping strategies in patients attending a dermatology outpatient clinic.

BACKGROUND: Psychological distress is frequent among dermatological patients. The development of a positive attitude toward diagnosis and treatment is thought to be critical for successful coping and mental health outcomes. OBJECTIVE: The aim of this study was to assess the coping strategies and the psychological distress, due to anxiety and depression, in an unselected sample of dermatological patients. METHODS: Self-administered questionnaires (HADS, COPE) were given to 603 dermatological patients. RESULTS: Out of 567 participants, 149 (26.2%) scored positive for Anxiety, and 52 (9.2%) scored positive for Depression. Multivariate analysis, adjusting for gender, age, socio-economic status, and disease, showed that both Anxiety and Depression are associated with a less frequent use of Positive attitude coping. CONCLUSION: Our results reinforce the notion that while planning the treatment of dermatological patients, evaluating their mental health might help to provide optimal treatment. Since coping ability was found to be important for mental health status, policy implications could include emphasis on social programs to assist individuals to manage stress, as well as psychological support.

Three-dimensional orientational order in the bulk and on the surface of polymer films and its effect on liquid-crystal alignment.

The correlation between orientation ordering of polymer chains in the bulk of polymer film and at the polymer-liquid-crystal (LC) interface has been studied to determine it's role in LC alignment. The bulk and surface ordering of polymer were investigated by null ellipsometry and x-ray reflectivity, respectively. Two kinds of liquid-crystalline polymers were used; side-chain azopolymers with azochromophores containing hydrophobic OC4H9 alkyl chain (P1) and strongly polar NO2 group (P2) as the end substituents. The uniaxial tilt orientation of azochromophores in the films of both polymers was induced by the oblique irradiation with unpolarized UV light. The two polymers exhibit similar chain orientation but different ordering of azochromophores on the surface of the films of P1 and P2. Surface ordering of P1 films correlates very well with the order in the bulk of the film, which are essentially determined by the UV exposure. However, orientational order of polymer chains at the surface of P2 films is different from that in its bulk and is not determined by UV exposure. This is explained by strong aggregation of azochromophores during its self-assembling at the polymer-air interface. The LC alignment is determined by the surface ordering of azochromophores. The results imply that ordering tendency can be effectively transferred from polymer bulk to polymer surface and then to LC if it is not lost at the polymer-LC interface.

Photoinduced three-dimensional orientational order in side chain liquid crystalline azopolymers.

We apply experimental technique based on the combination of methods dealing with principal refractive indices and absorption coefficients to study the photoinduced three-dimensional (3D) orientational order in the films of liquid crystalline (LC) azopolymers. The technique is used to identify 3D orientational configurations of trans azobenzene chromophores and to characterize the degree of ordering in terms of order parameters. We study two types of LC azopolymers which form structures with preferred in-plane and out-of-plane alignment of azochromophores, respectively. Using irradiation with the polarized light of two different wavelengths, we find that the kinetics of photoinduced anisotropy can be dominated by either photoreorientation (angular redistribution of trans chromophores) or photoselection (angular selective trans-cis isomerization) mechanisms depending on the wavelength. At the early stages of irradiation, the films of both azopolymers are biaxial. This biaxiality disappears on reaching a state of photosaturation. In the regime of photoselection, the photosaturated state of the film is optically isotropic. But, in the case of the photoreorientation mechanism, anisotropy of this state is uniaxial with the optical axis dependent on the preferential alignment of azochromophores. We formulate the phenomenological model describing the kinetics of photoinduced anisotropy in terms of the isomer concentrations and the order parameter tensor. We present the numerical results for absorption coefficients that are found to be in good agreement with the experimental data. The model is also used to interpret the effect of changing the mechanism with the wavelength of the pumping light.

Electroconvection in nematic liquid crystals with positive dielectric and negative conductivity anisotropy.

Electroconvection in an unusual nematic compound with strongly positive dielectric anisotropy and negative anisotropy of the conductivity is investigated. For homeotropic alignment, where one has a direct transition to rolls or squares depending on the frequency of the applied voltage, we present a quantitative theory. From the comparison we infer values for some viscosities, which are rather unusual, but not unreasonable in view of the vicinity of the nematic-smectic transition. For planar alignment, electroconvection sets in above a splay Freedericksz transition with "parallel rolls," which is also captured by the theory.

[Synthesis of cyclic and non-cyclic tachykinin partial sequences. 2. Synthesis of the homocyclic substance P(6-11) hexapeptide]. / Synthese cyclischer und cyclisch-verzweigter Tachykinin-Teilsequenzen. Teil 2: Darstellung des homodet-cyclischen Substanz P(6-11)-Hexapeptides.

The authors describe the synthesis of Gln-Phe-Phe-Gly-Leu-Met by cyclization of H-Leu-Met-Gln-Phe-Phe-Gly using three different methods. The linear sequence was obtained by a (2+4)-segment condensation. The resulting cyclopeptide showed only a small kinin activity on isolated guinea pig ileum compared to substance P, but it is a full agonist.

Validation of the Italian version of interpersonal sensitivity measure (IPSM) in adolescents and young adults.

BACKGROUND: Interpersonal sensitivity is a personality trait that describes as excessive awareness of both the behaviour and feelings of others. High interpersonal sensitivity has been associated with the development and maintenance of mental health problems. This study aimed to examine whether the Italian version of the interpersonal sensitivity measure (IPSM) has good internal consistence and convergent validity. METHODS: Validity was established on a sample of 153 Italian adolescents and young adult help seekers for several psychological problems. These subjects were divided in two groups - depressive spectrum disorder group (n=42) and other diagnosis group (n=111) - according to Structured Clinical Interview (SCID-I) for DSM-IV and Kiddie-Sads-Present and Lifetime Version (K-SADS-PL). For convergent validity, we studied the correlation between total and each subscale IPSM scores and the General Symptoms (included depressive and dysphoric symptoms) of Prodromal Questionnaire. RESULTS: The internal consistency were adequate and comparable to the original Boyce and Parker study. The validity was good, as indicated by both the convergent validity analysis and the depressive spectrum disorder group and other diagnosis group comparison. LIMITATIONS: The absence of another scale measuring interpersonal sensitivity to assess the construct validity of IPSM; the clinical heterogeneity of the sample; the absence of test re-test reliability of the instrument. CONCLUSIONS: Analysis of the results of internal consistency and convergent validity of the IPSM indicates that this version translated into Italian is valid and reliable.

[Early signs and symptoms before the psychotic onset. A study on the Duration of Untreated Illness (DUI) in a sample of patients with diagnosis of "non-affective psychotic disorders"]. / Segni e sintomi prodromici all'esordio psicotico. Uno studio sulla Duration of Untreated Illness (DUI) in un campione di pazienti con diagnosi di psicosi non affettiva.

AIMS: The aims of the study are to evaluate, in the Italian context, the presence and clinical features of early prodromal symptoms before the psychotic onset and, most of all, the duration of the period between the first onset of any psychiatric symptom and the psychotic onset (Duration of Untreated Illness). MATERIALS AND METHODS: The study was carried out on a sample of 296 inpatients with a diagnosis of "non-affective psychosis" enrolled in "Villa dei Fiori" inpatients Clinic in Rome. The retrospective analysis was developed using clinical records and clinical interview with patients and their parents. The evaluation of the psychotic onset and of DUI was assessed with the PANSS (Positive and Negative Symptoms Scale). RESULTS: The mean DUI is 4.7 ± 4.4 years. We found a connection between DUI and early symptoms of psycosis: depressive symptoms (4.9; DS=5.0) were most frequently observed, followed by anxiety symptoms (5.1; DS=4.8), eating disorders (5.7; DS=3.0); obsessive symptoms (4.5; DS=3.6); social withdrawal (5.9; DS=4.9); psychotic like symptoms (2.6; DS=1.3). DUI resulted lower in psychotic like symptoms than in the depressive ones. CONCLUSION: In Italy DUI turn out to be much longer than in other Country where do exists specialized services for early intervention. For this reason seem to be necessary to explore the opportunity to develop also in Italy specialized services for adolescents and young adults at risk and at their psychotic onset.
