Change in biased thinking in a 10-session treatment for borderline personality disorder: Further evidence of the motive-oriented therapeutic relationship.

Abstract Borderline Personality Disorder (BPD) is characterized by both maladaptive thinking and problematic schemas. Kramer and colleagues (2011) showed that using the motive-oriented therapeutic relationship (MOTR), based on the individualized understanding of the patient according to Plan Analysis (Caspar, 2007), can improve treatment outcomes for BPD. The present process-outcome pilot study aimed to examine the effects of the motive-oriented therapeutic relationship on the cognitive biases of patients with BPD. Change in biased cognitions in N=10 patients who were subject to MOTR was compared to that of N=10 patients who received psychiatric-psychodynamic treatment (Gunderson & Links, 2008). Results show a greater decrease in over-generalizations in patients who received MOTR, compared to the patients who received the psychiatric-psychodynamic treatment. These changes were related to outcome in various ways. These findings underline the importance of an individualized case formulation method in bringing about therapeutic change.

Functional dynamics of PDZ binding domains: a normal-mode analysis.

Postsynaptic density-95/disks large/zonula occludens-1 (PDZ) domains are relatively small (80-120 residues) protein binding modules central in the organization of receptor clusters and in the association of cellular proteins. Their main function is to bind C-terminals of selected proteins that are recognized through specific amino acids in their carboxyl end. Binding is associated with a deformation of the PDZ native structure and is responsible for dynamical changes in regions not in direct contact with the target. We investigate how this deformation is related to the harmonic dynamics of the PDZ structure and show that one low-frequency collective normal mode, characterized by the concerted movements of different secondary structures, is involved in the binding process. Our results suggest that even minimal structural changes are responsible for communication between distant regions of the protein, in agreement with recent NMR experiments. Thus, PDZ domains are a very clear example of how collective normal modes are able to characterize the relation between function and dynamics of proteins, and to provide indications on the precursors of binding/unbinding events.

Percepções de enfermeiras obstétricas sobre sua competência na atenção ao parto normal hospitalar

Investiga-se a percepção de enfermeiras obstétricas sobre sua competência na atenção ao parto normal (PN) hospitalar. Os dados foram coletados em pesquisa qualitativa, através de entrevistas individuais semi-estruturadas, realizadas em um hospital universitário de Porto Alegre, e submetidos à análise de conteúdo. A análise foi embasada nos referenciais que definem competência profissional como a capacidade de mobilizar diferentes conhecimentos, dependendo dos problemas da prática a resolver. Para as entrevistadas, a competência para atender o PN hospitalar é multidimensional, embora tenham enfatizado sua dimensão técnica. Essa ênfase é justificada pela insegurança resultante da falta de espaço para realizarem este atendimento, em função de disputas com médicos e deficiências na formação. O desejo de serem competentes no atendimento ao PN não se traduz, porém, na consciência das suas responsabilidades na transformação deste cenário. Isso sugere que, para agir nesta direção, seria necessário, não só desenvolver competência técnica, mas também ético-política.

Resultados maternos e neonatais em Centro de Parto Normal peri-hospitalar na cidade de São Paulo, Brasil

O objetivo foi descrever os resultados maternos e perinatais da assistência no Centro de Parto Normal Casa de Maria (CPN-CM), na cidade de São Paulo. A amostra probabilística foi de 991 parturientes e seus recém-nascidos, assistidos entre 2003 e 2006. Os resultados mostraram que 92,2% das parturientes tiveram um acompanhante de sua escolha e as práticas mais utilizadas no parto foram banho de aspersão ou imersão (92,9%), amniotomia (62,6%), deambulação (47,6%), massagem de conforto (29,8%) e episiotomia (25,7%). Com relação aos recém-nascidos, 99,9% apresentaram índice de Apgar = 7 no quinto minuto; 9,3% receberam aspiração das vias aéreas superiores; nenhum necessitou ser entubado; e 1,4% foram removidos para o hospital. O modelo de assistência praticado no CPN-CM apresenta resultados maternos e perinatais esperados para mulheres com baixo risco obstétrico, sendo alternativa segura e menos intervencionista no parto normal.

Induction of transendothelial migration in normal and malignant human T lymphocytes.

Activated CD 3+ enriched human peripheral blood T cells exhibited potent capacity for transendothelial migration through HUVEC layers in the absence of T cell ***. In contrast, malignant human T cell lines *** no or negligible ability of transendothelial migration in the absence of chemoattractants. Time lapse studies of transendothelial migration of activated CD 3+ enriched peripheral blood T cells through a HUVEC layer showed that the first T cells were detected in the lower compartment of a tissue culture insert after 1 hour and that migration increased to reach a maximum of 25 x 10(4) T cells/hr after 24 hours. Adhesion assays of human T cell lines demonstrated that all T cell lines were capable of adhesion to HUVEC and that adhesion of T cells to HUVECs was primarily mediated by CD11a/CD18 and ICAM-1 interactions. Furthermore, transendothelial migration of CD 3+ enriched human peripheral blood T cells was inhibited by pretreating the T cells with anti-CD 18 monoclonal antibodies. The inability of malignant T cells to migrate through HUVEC layers in the absence of chemoattractants was not due to poor motility per se, since both normal and malignant T cells migrated well on extracellular matrix components as determined by using Boyden chambers. Crosslinking of alpha 1 beta 2 and alpha 4 beta 1 with immobilized monoclonal antibodies induced motile behaviour in activated CD 3 enriched human peripheral blood T cells but not in malignant T cell lines. In conclusion, the differences in the ability of transendothelial migration between normal and malignant human T cells in the absence of chemoattractants is primarily due to the differences in the capacity of alpha 1 beta 2 and alpha 4 beta 1 to trigger motile behaviour in the separate cell types.

Quantitative distribution of parvalbumin, calretinin, and calbindin D-28k immunoreactive neurons in the visual cortex of normal and Alzheimer cases.

The distribution of parvalbumin (PV), calretinin (CR), and calbindin (CB) immunoreactive neurons was studied with the help of an image analysis system (Vidas/Zeiss) in the primary visual area 17 and associative area 18 (Brodmann) of Alzheimer and control brains. In neither of these areas was there a significant difference between Alzheimer and control groups in the mean number of PV, CR, or CB immunoreactive neuronal profiles, counted in a cortical column going from pia to white matter. Significant differences in the mean densities (numbers per square millimeter of cortex) of PV, CR, and CB immunoreactive neuronal profiles were not observed either between groups or areas, but only between superficial, middle, and deep layers within areas 17 and 18. The optical density of the immunoreactive neuropil was also similar in Alzheimer and controls, correlating with the numerical density of immunoreactive profiles in superficial, middle, and deep layers. The frequency distribution of neuronal areas indicated significant differences between PV, CR, and CB immunoreactive neuronal profiles in both areas 17 and 18, with more large PV than CR and CB positive profiles. There were also significantly more small and less large PV and CR immunoreactive neuronal profiles in Alzheimer than in controls. Our data show that, although the brain pathology is moderate to severe, there is no prominent decrease of PV, CR and CB positive neurons in the visual cortex of Alzheimer brains, but only selective changes in neuronal perikarya.

Como os trabalhadores de um Centro Obstétrico justificam a utilização de práticas prejudiciais ao parto normal

Este estudo busca entender as justificativas dos trabalhadores de um Centro Obstétrico do Sul do Brasil para a utilização de práticas do parto normal consideradas prejudiciais pela Organização Mundial da Saúde. A pesquisa é do tipo exploratória, desenvolvida em julho de 2009, por meio de entrevista com 23 trabalhadores. Na análise, houve a conformação de três núcleos temáticos: Ações e condutas na dependência do trabalhador de saúde; Práticas rotineiras como facilitadoras do trabalho e Restrição da participação da parturiente no processo decisório. Algumas justificativas para o emprego das práticas: perpetuação de modelos inadequados, facilitação para a assistência no momento do parto e autoritarismo que alguns trabalhadores exercem sobre a parturiente por acreditarem serem detentores do conhecimento.

Alpha1-adrenoceptors are required for normal male sexual function.

BACKGROUND AND PURPOSE: Alpha(1)-adrenoceptor antagonists are extensively used in the treatment of hypertension and lower urinary tract symptoms associated with benign prostatic hyperplasia. Among the side effects, ejaculatory dysfunction occurs more frequently with drugs that are relatively selective for alpha(1A)-adrenoceptors compared with other drugs of this class. This suggests that alpha(1A)-adrenoceptors may contribute to ejaculation. However, this has not been studied at the molecular level. EXPERIMENTAL APPROACH: The physiological contribution of each alpha(1)-adrenoceptor subtype was characterized using alpha(1)-adrenoceptor subtype-selective knockout (KO) mice (alpha(1A)-, alpha(1B)- and alpha(1D)-AR KO mice) since the subtype-specific drugs available are only moderately selective. We analysed the role of alpha(1)-adrenoceptors in the blood pressure and vascular response as well as ejaculation by determining these variables in alpha(1)-adrenoceptor subtype-selective KO mice and in mice with all their alpha(1)-adrenoceptor subtypes deleted (alpha(1)-AR triple-KO mice). KEY RESULTS: The pregnancy rate was reduced by 50% in alpha(1A)-adrenoceptor KO mice, and this reduction was dramatically enhanced in alpha(1)-adrenoceptor triple-KO mice. Contractile tension of the vas deferens in response to noradrenaline was markedly decreased in alpha(1A)-adrenoceptor KO mice, and this contraction was completely abolished in alpha(1)-adrenoceptor triple-KO mice. This attenuation of contractility was also observed in the electrically stimulated vas deferens. CONCLUSIONS AND IMPLICATIONS: These results demonstrate that alpha(1)-adrenoceptors, particularly alpha(1A)-adrenoceptors, are required for normal contractility of the vas deferens and consequent sperm ejaculation as well as having a function in fertility.

Prevalence of normal weight obesity in Switzerland: effects of various definitions

Background: normal weight obesity (NWO) is defined as an excessive body fat associated with a normal body mass index (BMI<25 kg/m2), but its prevalence in the general population is unknown. Objective: to assess the prevalence of NWO in Switzerland according to different cut points used to define excess body fat. Design: cross-sectional study including 3,213 women and 2,912 men aged 35-75 years. Body fat was assessed by bioimpedance and prevalence of NWO was assessed using four previously published definitions for excess body fat. Results: % body fat increased with age: in men, the values (mean SD) were 20.2 5.4, 23.0 5.4, 26.3 5.2 and 28.2 4.6 for age groups [35 - 44], [45 - 54], [55 - 64] and [65 - 75] years, respectively; the corresponding values for women were 29.9 7.8, 33.1 7.4, 36.7 7.5 and 39.6 6.9. In men, prevalence of NWO was <1% irrespective of the definition used. Conversely, in women, a one to twenty fold difference (from 1.4% to 27.8%) in NWO prevalence was found. The prevalence of NWO increased with age when age-independent cut points were used in women, but not in men. Conclusions: prevalence of NWO is low in the general population and higher in women than in men. The prevalence is highly dependent on the criteria used to define excess body fat, namely in women. The use of gender- and age-specific cut points to define excess body fat is better than fixed or gender-specific only cut points.

Emotional processing in a ten-session general psychiatric treatment for borderline personality disorder: a case study.

This study examines the effects of a borderline-specific treatment, called general psychiatric management, on emotional change, outcome and therapeutic alliance of an outpatient presenting with borderline personality disorder. Based on the sequential model of emotional processing, emotional states were assessed in a 10-session setting. The case showed an increase in expressions of distress and no change in therapeutic alliance and tended towards general deterioration. Results suggest emotional processing may play a lesser role in general psychiatric management in early phase treatment than previously hypothezised. Copyright © 2015 John Wiley & Sons, Ltd.

Ultrahigh dose-rate FLASH irradiation increases the differential response between normal and tumor tissue in mice.

In vitro studies suggested that sub-millisecond pulses of radiation elicit less genomic instability than continuous, protracted irradiation at the same total dose. To determine the potential of ultrahigh dose-rate irradiation in radiotherapy, we investigated lung fibrogenesis in C57BL/6J mice exposed either to short pulses (≤ 500 ms) of radiation delivered at ultrahigh dose rate (≥ 40 Gy/s, FLASH) or to conventional dose-rate irradiation (≤ 0.03 Gy/s, CONV) in single doses. The growth of human HBCx-12A and HEp-2 tumor xenografts in nude mice and syngeneic TC-1 Luc(+) orthotopic lung tumors in C57BL/6J mice was monitored under similar radiation conditions. CONV (15 Gy) triggered lung fibrosis associated with activation of the TGF-β (transforming growth factor-β) cascade, whereas no complications developed after doses of FLASH below 20 Gy for more than 36 weeks after irradiation. FLASH irradiation also spared normal smooth muscle and epithelial cells from acute radiation-induced apoptosis, which could be reinduced by administration of systemic TNF-α (tumor necrosis factor-α) before irradiation. In contrast, FLASH was as efficient as CONV in the repression of tumor growth. Together, these results suggest that FLASH radiotherapy might allow complete eradication of lung tumors and reduce the occurrence and severity of early and late complications affecting normal tissue.

Long-term outcome after cognitive and behavioral regression in non-lesional epilepsy with CSWS

Purpose: To present the long-term outcome (LTO) of 10 adolescents and young adults with documented cognitive and behavioral regression as children due to non-lesional focal, mainly frontal epilepsy with continuous spike-waves during slow wave sleep (CSWS). Method: Past medical and EEG data of all patients were reviewed and neuropsychological tests exploring main cognitive functions were administered. Result: After a mean duration of follow-up of 15.6 years (range 8-23 years), none of the 10 patients had recovered fully, but four regained borderline to normal intelligence and were almost independent. Patients with prolonged global intellectual regression had the worst outcome, whereas those with more specific and short-lived deficits recovered best. The marked behavioral disorders that were so disturbing during the active period (AP) resolved in all but one patient. Executive functions were neither severely nor homogenously affected. Three patients with a frontal syndrome during the AP disclosed only mild residual executive and social cognition deficits. The main cognitive gains occurred shortly after the AP, but qualitative improvements continued to occur. LTO correlated best with duration of CSWS. Conclusion: Our findings emphasize that cognitive recovery after cessation of CSWS depends on the severity and duration of the initial regression. None of our patients had major executive and social cognition deficits with preserved intelligence as reported in adults with destructive lesions of the frontal lobes during childhood. Early recognition of epilepsy with CSWS and rapid introduction of effective therapy are crucial for a best possible outcome.

Adherence to best care practices in normal birth: construction and validation of an instrument

Abstract OBJECTIVE To describe the stages of construction and validation of an instrument in order to analyze the adherence to best care practices during labour and birth. METHOD Methodological research, carried out in three steps: construction of dimensions and items, face and content validity and semantic analysis of the items. RESULTS The face and content validity was carried out by 10 judges working in healthcare, teaching and research. Items with Content Validity Index (CVI) ≥ 0.9 were kept in full or undergone revisions as suggested by the judges. Semantic analysis, performed twice, indicated that there was no difficulty in understanding the items. CONCLUSION The instrument with three dimensions (organization of healthcare network to pregnancy and childbirth, evidence-based practices and work processes) followed the steps recommended in the literature, concluded with 50 items and total CVI of 0.98.
