Beyond splitting: observer-rated defense mechanisms in borderline personality disorder

Defense mechanism is a key concept in the psychoanalytic psychopathology of borderline personality disorder (BPD). Theoretical and empirical elaborations on this question are briefly reviewed and discussed with respect to process assessment of defense mechanisms; we put forward observer-rater methodology as an accurate means of assessing unconscious in-session processes. A sample of 25 patients presenting with BPD were interviewed, as were subjects from a matched control group without psychiatric symptoms (n = 25), using a psychodynamic interview paradigm. These interviews were transcribed and rated using the Defense Mechanisms Rating Scales. The results indicate that, compared to controls, patients with BPD used higher percentages of a action, borderline, disavowal, narcissistic, and hysteric defenses, along with lower levels of mature and obsessional defenses. Overall defensive functioning was significantly lower in the patients with BPD, compared to controls. Narcissistic defenses were related with symptom level. These results are discussed in light of previous studies on defensive functioning of BPD and the literature on psychoanalytic psychopathology. These results have several important clinical implications.

Sequence-Based Hepatitis B Virus Antiviral Resistance Testing in Switzerland

BACKGROUND: A growing number of patients with chronic hepatitis B is being treated for extended periods with nucleoside and/or nucleotide analogs. In this context, antiviral resistance represents an increasingly common and complex issue. METHODS: Mutations in the hepatitis B virus (HBV) reverse transcriptase (rt) gene and viral genotypes were determined by direct sequencing of PCR products and alignment with reference sequences deposited in GenBank. RESULTS: Plasma samples from 60 patients with chronic hepatitis B were analyzed since March 2009. The predominant mutation pattern identified in patients with virological breakthrough was rtM204V/I ± different compensatory mutations, conferring resistance to L-nucleosides (lamivudine, telbivudine, emtricitabine) and predisposing to entecavir resistance (n = 18). Complex mutation patterns with a potential for multidrug resistance were identified in 2 patients. Selection of a fully entecavir resistant strain was observed in a patient exposed to lamivudine alone. Novel mutations were identified in 1 patient. Wild-type HBV was identified in 9 patients with suspected virological breakthrough, raising concerns about treatment adherence. No preexisting resistance mutations were identified in treatment-naïve patients (n = 13). Viral genome amplification and sequencing failed in 16 patients, of which only 2 had a documented HBV DNA > 1000 IU/ml. HBV genotypes were D in 28, A in 6, B in 4, C in 3 and E in 3 patients. Results will be updated in August 2010 and therapeutic implications discussed. CONCLUSIONS: With expanding treatment options and a growing number of patients exposed to nucleoside and/or nucleotide analogs, sequence-based HBV antiviral resistance testing is expected to become a cornerstone in the management of chronic hepatitis B.

L'intégration de la sexualité en consultation gynécologique : discordances entre les perceptions des femmes et celles des gynécologues.

Dès les années 2000, l'Office Fédéral de la Santé Publique recommande aux médecins de premier recours, dont les gynécologues, d'aborder activement la sexualité en consultation, en raison notamment de l'augmentation des infections sexuellement transmissibles asymptomatiques (1ST). Dans le même sens, comme le montrent nombre d'études, plus de 70% des patientes souhaiteraient être interrogées au sujet de leur sexualité en consultation gynécologique. Or, il semble que peu de médecins intègrent systématiquement des questions de sexualité dans leur anamnèse. La revue de la littérature relève que les recherches réalisées à ce jour ont été menées principalement à l'aide de questionnaire selon une perspective naturaliste, qui étudie la sexualité de manière décontextualisée et qui la conçoit comme un invariant biologique et par conséquent universel. Notre objectif est de saisir en profondeur les perceptions et le vécu des gynécologues et des femmes, face à l'intégration de la sexualité en consultation gynécologique. Nous avons adopté une perspective critique en psychologie de la santé (Santiago-Delefosse & Chamberlain, 2008 ; Murray, 2004a ; Lyons & Chamberlain, 2006) qui permet de privilégier d'une part, l'étude de la signification que les sujets donnent à la sexualité dans leur contexte socio-historique et, d'autre part, une vision de l'être humain comprenant des dimensions corporelles, psychologiques et sociétales (Santiago-Delefosse, 2011). Pour ce faire, nous avons utilisé un dispositif de méthodes mixtes en deux phases. Dans la première phase, nous avons mené 21 entretiens semi directifs avec des gynécologues hommes et femmes. Puis, nous avons réalisé 3 groupes focalisés (N=16) avec des femmes âgées de 23 à 65 ans. La seconde phase a consisté à créer un questionnaire, élaboré à partir des résultats de la première phase, afin d'élargir l'expérience de l'intégration de la sexualité en consultation, à une population plus diversifiée de femmes (N=421). Les données récoltées par le biais de ces trois méthodes nous ont permis d'esquisser un modèle présentant les processus en jeu dans la situation de non intégration de la sexualité en consultation gynécologique. Celui-ci relève non seulement des lacunes dans le cursus universitaire de médecine en matière de sexualité, mais également d'importantes discordances entre les gynécologues et les femmes interviewés concernant le rôle du gynécologue, la perception de l'intime, la perception d'introduire le sujet de la sexualité en consultation, ainsi que de la définition même de la sexualité. Nos résultats ouvrent sur des perspectives pratiques pour la consultation gynécologique, ainsi que sur des pistes pour des recherches futures dans l'étude de la sexualité, selon une perspective plus intégrative. -- Since the 2000's, the Swiss Federal Office of Public Health recommended primary care physicians, including gynaecologists, to actively address sexuality issues in consultation, namely because of the increasing incidence of Sexually Transmitted Infections (STI). In line with this, studies have shown that more than 70% of patients would like to be asked about their sexuality by their gynaecologist. However, physicians do not take systematically sexual histories from their patients. Literature in the field has highlighted that most research has been restricted to using questionnaires following a naturalist theoretical perspective according to which sexual behaviour is defined as biologically invariant, hence, universal. Our objective is to deepen understand perceptions from gynaecologists and women with regard to the integration of sexuality in consultations. A critical health psychology approach allows us to consider on the one hand sexuality as a construct that is inseparable from a given socio-historical context. On the other hand, this approach takes into consideration an embodied, social and psychological definition of human beings. Therefore, we used a mixed methods design that included two main research steps : First, we conducted 21 semi-structured interviews with male and female gynaecologists. In this phase, we also led 3 focus groups made up of 16 women aged from 21 to 65. Second, a survey was implemented (N= 421) based on findings stemming from the first phase. This allowed us to further analyse experiences on the integration of sexuality and to extend findings to a more diversified population of women. The data analysis allowed us to create a model that highlights the processes involved in the non integration of sexuality during gynaecological consultation. It shows a lack of training in sexology within medical programs. Moreover, it emphasises the mismatches on perceptions between gynaecologists and women concerning the gynaecologist's role ; intimacy, the issue of whether introducing sexuality topics, and finally, on the actual definition of sexuality itself. Our findings open new research perspectives for the study of sexuality by proposing a more integrative approach. They also provide practical and clinical perspectives concerning consultations in gynaecology.

"INTERMED": a method to assess health service needs. I. Development and reliability.

The purpose of this paper is to describe the development and to test the reliability of a new method called INTERMED, for health service needs assessment. The INTERMED integrates the biopsychosocial aspects of disease and the relationship between patient and health care system in a comprehensive scheme and reflects an operationalized conceptual approach to case mix or case complexity. The method is developed to enhance interdisciplinary communication between (para-) medical specialists and to provide a method to describe case complexity for clinical, scientific, and educational purposes. First, a feasibility study (N = 21 patients) was conducted which included double scoring and discussion of the results. This led to a version of the instrument on which two interrater reliability studies were performed. In study 1, the INTERMED was double scored for 14 patients admitted to an internal ward by a psychiatrist and an internist on the basis of a joint interview conducted by both. In study 2, on the basis of medical charts, two clinicians separately double scored the INTERMED in 16 patients referred to the outpatient psychiatric consultation service. Averaged over both studies, in 94.2% of all ratings there was no important difference between the raters (more than 1 point difference). As a research interview, it takes about 20 minutes; as part of the whole process of history taking it takes about 15 minutes. In both studies, improvements were suggested by the results. Analyses of study 1 revealed that on most items there was considerable agreement; some items were improved. Also, the reference point for the prognoses was changed so that it reflected both short- and long-term prognoses. Analyses of study 2 showed that in this setting, less agreement between the raters was obtained due to the fact that the raters were less experienced and the scoring procedure was more susceptible to differences. Some improvements--mainly of the anchor points--were specified which may further enhance interrater reliability. The INTERMED proves to be a reliable method for classifying patients' care needs, especially when used by experienced raters scoring by patient interview. It can be a useful tool in assessing patients' care needs, as well as the level of needed adjustment between general and mental health service delivery. The INTERMED is easily applicable in the clinical setting at low time-costs.

Transapical aortic valve implantation without angiography: proof of concept.

Background: Cardiac computed tomographic scans, coronary angiograms, and aortographies are routinely performed in transcatheter heart valve therapies. Consequently, all patients are exposed to multiple contrast injections with a following risk of nephrotoxicity and postoperative renal failure. The transapical aortic valve implantation without angiography can prevent contrast-related complications. Methods: Between November 2008 and November 2009, 30 consecutive high-risk patients (16 female, 53.3%) underwent transapical aortic valve implantation without angiography. The landmarks identification, the stent-valve positioning, and the postoperative control were routinely performed under transesophageal echocardiogram and fluoroscopic visualization without contrast injections. Results: Mean age was 80.1 +/- 8.7 years. Mean valve gradient, aortic orifice area, and ejection fraction were 60.3 +/- 20.9 mm Hg, 0.7 +/- 0.16 cm(2), and 0.526 +/- 0.128, respectively. Risk factors were pulmonary hypertension (60%), peripheral vascular disease (70%), chronic pulmonary disease (50%), previous cardiac surgery (13.3%), and chronic renal insufficiency (40%) (mean blood creatinine and urea levels: 96.8 +/- 54 mu g/dL and 8.45 +/- 5.15 mmol/L). Average European System for Cardiac Operative Risk Evaluation was 32.2 +/- 13.3%. Valve deployment in the ideal landing zone was 96.7% successful and valve embolization occurred once. Thirty-day mortality was 10% (3 patients). Causes of death were the following: intraoperative ventricular rupture (conversion to sternotomy), right ventricular failure, and bilateral pneumonia. Stroke occurred in one patient at postoperative day 9. Renal failure (postoperative mean blood creatinine and urea levels: 91.1 +/- 66.8 mu g/dL and 7.27 +/- 3.45 mmol/L), myocardial infarction, and atrioventricular block were not detected. Conclusions: Transapical aortic valve implantation without angiography requires a short learning curve and can be performed routinely by experienced teams. Our report confirms that this procedure is feasible and safe, and provides good results with low incidence of postoperative renal disorders.

Loss of ATF2 function leads to cranial motoneuron degeneration during embryonic mouse development.

The AP-1 family transcription factor ATF2 is essential for development and tissue maintenance in mammals. In particular, ATF2 is highly expressed and activated in the brain and previous studies using mouse knockouts have confirmed its requirement in the cerebellum as well as in vestibular sense organs. Here we present the analysis of the requirement for ATF2 in CNS development in mouse embryos, specifically in the brainstem. We discovered that neuron-specific inactivation of ATF2 leads to significant loss of motoneurons of the hypoglossal, abducens and facial nuclei. While the generation of ATF2 mutant motoneurons appears normal during early development, they undergo caspase-dependent and independent cell death during later embryonic and foetal stages. The loss of these motoneurons correlates with increased levels of stress activated MAP kinases, JNK and p38, as well as aberrant accumulation of phosphorylated neurofilament proteins, NF-H and NF-M, known substrates for these kinases. This, together with other neuropathological phenotypes, including aberrant vacuolisation and lipid accumulation, indicates that deficiency in ATF2 leads to neurodegeneration of subsets of somatic and visceral motoneurons of the brainstem. It also confirms that ATF2 has a critical role in limiting the activities of stress kinases JNK and p38 which are potent inducers of cell death in the CNS.
