Using plan analysis in psychotherapeutic case formulation of borderline personality disorder.

A comprehensive understanding of the patient's problems is essential for a constructive therapeutic behaviour, especially in borderline personality disorder (BPD) where difficult interpersonal patterns are persistent. In these circumstances, the use of an integrative case formulation approach such as Plan Analysis, developed by K. Grawe and F. Caspar, can be of help for therapy planning. The focus here is on instrumental relations between behaviours and the hypothetical Plans and motives 'behind' those behaviours. The present qualitative study aimed at setting a prototypical Plan structure for n = 15 patients presenting a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnosis of BPD using Plan Analysis. The first psychotherapeutic session of every outpatient was video-taped and evaluated according to the Plan Analysis procedure. Inter-rater reliability was established between two independent raters and was considered sufficient. The detailed prototypical Plan structure of BPD showed two main tendencies: first, the important presence of support-seeking among these patients and second, the will to be in control and to protect oneself. This study confirms the existence of several core similarities in the functioning of patients with BPD. These findings are in line with earlier studies and expand the latter with the aim of contributing to the understanding of BPD psychopathology. Clinical implications are discussed. Copyright © 2011 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Plan Analysis can especially be of help with patients who have difficult interpersonal patterns, as those presenting with BPD. Two tendencies were found within BPD patients: (1) support-seeking and (2) control and self-protecting Plans. Further research using Plan Analysis should focus on the identification and detail of emotions within BPD.

Synthesis of triheptanoin and formulation as a solid diet for rodents

Triheptanoin-enriched diets have been successfully used in the experimental treatment of various metabolic disorders. Maximal therapeutic effect is achieved in the context of a ketogenic diet where triheptanoin oil provides 3040% of the daily caloric intake. However, pre-clinical studies using triheptanoin-rich diets are hindered by the difficulty of administering to laboratory animals as a solid foodstuff. In the present study, we successfully synthesized triheptanoin to the highest standards of purity from glycerol and heptanoic acid, using sulfonated charcoal as a catalyst. Triheptanoin oil was then formulated as a solid, stable and palatable preparation using a ketogenic base and a combination of four commercially available formulation agents: hydrophilic fumed silica, hydrophobic fumed silica, microcrystalline cellulose, and talc. Diet compliance and safety was tested on C57Bl/6 mice over a 15-week period, comparing overall status and body weight change. Practical applications: This work provides a complete description of (i) an efficient and cost-effective synthesis of triheptanoin and (ii) its formulation as a solid, stable, and palatable ketogenic diet (triheptanoin-rich; 39% of the caloric intake) for rodents. Triheptanoin-rich diets will be helpful on pre-clinical experiments testing the therapeutic efficacy of triheptanoin in different rodent models of human diseases. In addition, using the same solidification procedure, other oils could be incorporated into rodent ketogenic diet to study their dosage and long-term effects on mammal health and development. This approach could be extremely valuable as ketogenic diet is widely used clinically for epilepsy treatment.

An operator formulation of the multiscale finite-volume method with correction function

The multiscale finite-volume (MSFV) method has been derived to efficiently solve large problems with spatially varying coefficients. The fine-scale problem is subdivided into local problems that can be solved separately and are coupled by a global problem. This algorithm, in consequence, shares some characteristics with two-level domain decomposition (DD) methods. However, the MSFV algorithm is different in that it incorporates a flux reconstruction step, which delivers a fine-scale mass conservative flux field without the need for iterating. This is achieved by the use of two overlapping coarse grids. The recently introduced correction function allows for a consistent handling of source terms, which makes the MSFV method a flexible algorithm that is applicable to a wide spectrum of problems. It is demonstrated that the MSFV operator, used to compute an approximate pressure solution, can be equivalently constructed by writing the Schur complement with a tangential approximation of a single-cell overlapping grid and incorporation of appropriate coarse-scale mass-balance equations.

A single dose of intravenous esomeprazole decreases gastric secretion in healthy volunteers.

BACKGROUND: Data suggest that esomeprazole decreases gastric secretion. AIMS: To assess the effect of a single i.v. esomeprazole dose on gastric secretion volume 3 h after drug administration, as a primary endpoint, and to evaluate, as secondary endpoints, the reduction 1 and 5 h after dosing; time when the gastric pH was <2.5 and esomeprazole's safety. METHODS: In all, 23 healthy Helicobacter pylori-negative volunteers (10 men, 13 women, mean age 28.2 +/- 6) participated in this single-centre, randomized, double-blind, placebo-controlled, 2-way, single-dose cross-over study. In different sessions, volunteers received i.v. either esomeprazole 40 mg or placebo. An inserted double-lumen nasogastric tube perfused and aspirated gastric liquid. Mechanical fractioned aspiration measured secretion volume; aliquot spectrophotometry assessed gastric secretion volume lost to the duodenum. RESULTS: Three hours post-i.v. esomeprazole, average gastric secretion decreased by 77.6% (vs. baseline) compared to placebo. Values 1 and 5 h after dosing were 73.5% and 74.5%. Five hours after esomeprazole, the gastric pH was <2.5 3.9% of the time and 73.3% after placebo (P < 0.002). Esomeprazole was well-tolerated. No serious adverse events occurred. CONCLUSIONS: Intravenous esomeprazole decreases gastric secretions. The potential clinical impact in averting bronchoaspiration during anaesthesia induction and in intensive care patients should be investigated in further studies.

Is diagnosis enough to guide interventions in mental health? Using case formulation in clinical practice.

ABSTRACT: While diagnosis has traditionally been viewed as an essential concept in medicine, particularly when selecting treatments, we suggest that the use of diagnosis alone may be limited, particularly within mental health. The concept of clinical case formulation advocates for collaboratively working with patients to identify idiosyncratic aspects of their presentation and select interventions on this basis. Identifying individualized contributing factors, and how these could influence the person's presentation, in addition to attending to personal strengths, may allow the clinician a deeper understanding of a patient, result in a more personalized treatment approach, and potentially provide a better clinical outcome.

Pegfilgrastim to accelerate neutrophil engraftment following peripheral blood stem cell transplant and reduce the duration of neutropenia, hospitalization, and use of intravenous antibiotics: a phase II study in multiple myeloma and lymphoma and comparison with filgrastim-treated matched controls.

This trial was aimed to explore the efficacy of pegfilgrastim to accelerate neutrophil engraftment after stem cell autotransplant. Twenty patients with multiple myeloma and 20 with lymphoma received pegfilgrastim 6 mg on day +1. Forty cases treated with daily filgrastim starting at median day +7 (5-7), matched by age, sex, diagnosis, high-dose chemotherapy schedule, CD34 +  cell-dose, and prior therapy lines, were used for comparison. Median time to neutrophil engraftment was 9.5 vs. 11 days for pegfilgrastim and filgrastim, respectively (p < 0.0001). Likewise, duration of neutropenia, intravenous antibiotic use, and hospitalization favored pegfilgrastim, while platelet engraftment, transfusion requirement, and fever duration were equivalent in both groups. No grade  ≥ 3 toxicities were observed. Patients with lymphoma performed similarly to the entire cohort, while patients with myeloma showed faster neutrophil engraftment and shorter neutropenia but not shorter hospitalization and antibiotic use. The possibility of different outcomes for lymphoma and myeloma suggests that stratification by diagnosis may be useful in future phase III studies.

Intravenous fish oil blunts the physiological response to endotoxin in healthy subjects

Résumé L'administration par voie orale d'acides gras polyinsaturés de type ω-3 contenus dans l'huile de poisson exerce des effets bénéfiques sur la réponse métabolique et inflammatoire chez des sujets sains soumis à une injection d'endotoxine. Ce modèle expérimental a été validé pour l'investigation clinique. Il simule un sepsis et induit une réponse comparable à un état grippal, accompagné de modifications métaboliques et inflammatoires. L'objectif de cette étude est de déterminer les effets de l'huile de poisson administré par voie intraveineuse sur la réponse à l'endotoxine chez le sujet sain. L'hypothèse est qu'il sera possible de réduire le temps de latence en comparaison avec la voie orale. Pour ce faire, nous avons inclut dans une étude prospective randomisée 16 volontaires sains âgés de 16 à 35 ans et les avons répartis en 2 groupes : l'un recevant une émulsion lipidique contenant les acides gras polyinsaturés EPA et DHA et l'autre, sans traitement, constituant le groupe contrôle. Huit sujets reçoivent une perfusion continue de 0.5g/kg d'huile de poisson durant 6h, 48h et 24h avant la journée test. Lors de cette journée test, tous les volontaires ont reçu une dose d'endotoxine (2mg/kg) au temps t0. Les paramètres vitaux sont monitorés et enregistrés : fréquence cardiaque, respiratoire, pression artérielle, saturation artérielle en oxygène, ainsi que température. Des prises de sang sont effectuées à intervalles réguliers pour déterminer 1) l'incorporation membranaire des thrombocytes en EPA et DHA ; 2) le taux plasmatique d'hormones (insulin, glucagon, cortisol, ACTH et catécholamines), de marqueurs inflammatoires (TNF-α, IL-6, hsCRP), ainsi que de substrats énergétiques (glucose, lactate, acides gras libres et triglycérides). La dépense énergétique est déterminée par calorimétrie indirecte. L'analyse statistique est effectuée par analyse de variance (ANOVA). Les résultats montrent une incorporation significative de EPA et DHA au niveau membranaire des thrombocytes. L'huile de poisson induit une atténuation significative de la réponse neuro-endocrinienne et inflammatoire en réponse à l'injection d'endotoxine avec diminution de la fièvre (-0.7°C), ainsi que du taux plasmatique ,d'ACTH (-68%), TNF-α (-63%) et de noradrénaline (-%) dans le groupe huile de poisson. En conclusion, cette étude montre que la supplémentation de 2 doses d'huile de poisson par voie intraveineuse modifie la composition phospholipidique des membranes des thrombocytes et diminue la réaction inflammatoire et neuroendocrinienne en réponse à l'endotoxine. Ces résultats positifs ouvrent la perspective d'une supplémentation parentérale préopératoire en acides gras polyinsaturés ω-3 pour diminuer le stress lié à la chirurgie majeure.

Intravenous pamidronate as treatment for osteoporosis after heart transplantation: a prospective study.

Fractures due to osteoporosis are one of the major complications after heart transplantation, occurring mostly during the first 6 months after the graft, with an incidence ranging from 18% to 50% for vertebral fractures. Bone mineral density (BMD) decreases dramatically following the graft, at trabecular sites as well as cortical sites. This is explained by the relatively high doses of glucocorticoids used during the months following the graft, and by a long-term increase of bone turnover which is probably due to cyclosporine. There is some evidence for a beneficial effect on BMD of antiresorptive treatments after heart transplantation. The aim of this study was to assess prospectively the effect on BMD of a 3-year treatment of quarterly infusions of 60 mg of pamidronate, combined with 1 g calcium and 1000 U vitamin D per day, in osteoporotic heart transplant recipients, and that of a treatment with calcium and vitamin D in heart transplant recipients with no osteoporosis. BMD of the lumbar spine and the femoral neck was measured by dual-energy X-ray absorptiometry in all patients every 6 months for 2 years and after 3 years. Seventeen patients, (1 woman, 16 men) aged 46+/-4 years (mean +/- SEM) received only calcium and vitamin D. A significant decrease in BMD was observed after 6 months following the graft, at the lumbar spine (- 6.6%) as well as at the femoral neck (-7.8%). After 2 years, BMD tended to recover at the lumbar spine, whereas the loss persisted after 3 years at the femoral neck. Eleven patients (1 woman and 10 men) aged 46+/-4 years (mean +/- SEM) started treatment with pamidronate on average 6 months after the graft, because they had osteoporosis of the lumbar spine and/or femoral neck (BMD T-score below -2.5 SD). Over the whole treatment period, a continuous increase in BMD at the lumbar spine was noticed, reaching 18.3% after 3 years (14.3% compared with the BMD at the time of the graft). BMD at the femoral neck was lowered in the first year by -3.4%, but recovered totally after 3 years of treatment. In conclusion, a 3-year study of treatment with pamidronate given every 3 months to patients with existing osteoporosis led to a significant increase in lumbar spine BMD and prevented loss at the femoral neck. However, since some of these patients were treated up to 14 months after the transplant, they may already have passed through the phase of most rapid bone loss. In patients who were not osteoporotic at baseline, treatment with calcium and vitamin D alone was not able to prevent the rapid bone loss that occurs immediately after transplantation.

Blunting the response to endotoxin in healthy sujects : effects of various dose of intravenous fish oil

Enjeux et contexte La recherche de cette dernière décennie sur les acides gras n-3 PUFA contenus dans l'huile de poisson a montré que ceux-ci, et particulièrement l'ΕΡΑ et le DHA, avaient des propriétés anti¬inflammatoires et anti arythmiques puissantes, potentiellement utiles chez les septiques et « cardiaques ». Les mécanismes sous-jacents sont nombreux, incluant l'incorporation des acides gras dans les membranes de phopholipides, la réduction de la production de médiateurs pro-inflammatoires (prostaglandines, leukotrienes, thromboxane), l'augmentation de la production de résolvines et protectines dérivées du DHA, et la régulation de voies de signalisation cellulaire. Cependant, les doses de n-3 PUFA utilisées dans les études cliniques et chez le sujet sain avant le travail de Yann-Karim Pittet étaient nettement supérieures aux doses nutritionnelles de l'ordre de 5-8 g/j par voie orale ou 1 g/kg par voie intraveineuse. De plus, la voie entérale avait la réputation de nécessiter plusieurs jours à semaines de traitement avant d'aboutir à une incorporation d'acides gras membranaire suffisante pour avoir un impact clinique; quant au temps minimal requis pour obtenir cet effet par voie IV, il était inconnu. Depuis, le développement d'émulsions lipidiques intraveineuses destinées à la nutrition parentérale a permis d'imaginer l'administration de prétraitements IV rapides. Pour les étudier, notre laboratoire a développé un modèle d'endotoxine (LPS d'E.Coli) qui mime les réponses physiologique, endocrinienne et biologique du sepsis chez le sujet sain, utilisant des doses de 2 ng/kg IV. Les réponses sont totalement réversibles en 8 heures. Dans le but de réduire à la fois la dose de lipides et le temps de perfusion, ce travail a étudié l'influence de 3 doses dégressives de n-3 PUFA sur les réponses à l'endotoxine, et sur l'incorporation membranaire de ces acides gras. Méthodes Etude prospective chez 3 groupes consécutifs de sujets sains soumis à un challenge d'endotoxine. Intervention : perfusions d'huile de poisson (0.5 et 0.2 g/kg de n-3 PUFA, Omegaven® 10%) ou placebo, administrées en 3 heures ou en 1 heure, soit le jour avant ou le jour-même du test d'endotoxine. Mesures : variables physiologiques (T°, fc, tension artérielle, calorimétrie indirecte) Laboratoire - prises de sang à T0, 60, 120 et 360 min après l'injection de LPS: TNF-α, hs-CRP, hormones de stress, composition en acides gras des membranes plaquettaires. Statistiques Les résultats ont été rapportés en moyennes et écarts types. Des aires sous la courbe (AUC) ont été calculées avec la méthode des parallélépipèdes pour toutes les variables déterminées de manière répétée. L'effet du temps a été exploré par des two-way ANOVA pour mesures répétées. Les comparaisons post-hoc ont été réalisées avec des tests de Dunnett's ou de Scheffe. Les modifications de composition membranaires ainsi que les AUC ont été analysées par des tests non-paramétriques (Kruskal-Wallis). Résultats Après LPS, la température, les concentrations d'ACTH et TNF-α ont augmenté dans les 3 groupes. Ces réponse ont été significativement atténuées (p<0.0001) par l'huile de poisson comparé à ce que nous avions observé dans le groupe contrôle de Pluess et al (ICM 2007). Les concentrations les plus faibles d'ACTH, de TNF-α, et les AUC les plus basses des températures, ont été observées après une dose unique de 0.2 g/kg de n-3 PUFA administrée 1 heure avant le LPS. Par contre, l'incorporation membranaire d'EPA est dose-dépendante. Conclusions Sachant que la réponse à l'endotoxine est reproductible, cette étude montre que 3 doses différentes d'huile de poisson atténuent de manière différente cette réponse. La perfusion de 0.2 g/kg administrée juste avant l'endotoxine s'est avérée la plus efficace à atténuer la réponse fébrile, les cytokines et les hormones de stress, suggérant une capture de l'endotoxine par l'émulsion lipidique qui se surajoute aux effets systémiques et membranaires.
