Causal linear parametric model for baroreflex gain assessment in patients with recent myocardial infarction

2001

Spectral and cross-spectral analysis of R-R interval and systolic arterial pressure (SAP) spontaneous fluctuations have been proposed for noninvasive evaluation of baroreflex sensitivity (BRS). However, results are not in good agreement with clinical measurements. In this study, a bivariate parametric autoregressive model with exogenous input (ARXAR model), able to divide the R-R variability into SAP-related and -unrelated parts, was used to quantify the gain (αARXAR) of the baroreflex regulatory mechanism. For performance assessing, two traditional noninvasive methods based on frequency domain analysis [spectral, baroreflex gain by autogressive model (αAR); cross-spectral, baroreflex gain…

Low target birth weight or growth retardation? Umbilical Doppler flow velocity waveforms and histometric analysis of fetoplacental vascular tree

1993

Objective: The placental vascular architecture of small-for-gestatonal-age fetuses seems to have an impact on the flow patterns in the umbilical arteries. Study Design: Blood flow velocity waveforms of the umbilical arteries were measured by Doppler ultrasonography in nine small-for-gestational-age fetuses with elevated systolic/diastolic ratios of the umbilical arteries, seven small-for-gestational-age fetuses with normal flow patterns, and 14 appropriate-for-gestational-age fetuses with normal flow patterns. After delivery histomorphometric placental investigations were performed. Results: Reduced end-diastolic flow velocities were significantly associated with both a reduction of vascula…

Efficacy and predictors of outcome of short-term psychodynamic psychotherapy (stpp) in depressed breast cancer patients: A randomised controlled trial

2013

Results: 34 people made up the data set. 25/34 (74%) answered the questionnaire. 11/25(44%) had suicidal thoughts in the previous 72 hours. 3/34 (9%) had deliberately self-harmed in the previous 72 hours. 29/34 (85%) stated that the needle exchange would be their first contact point in health care if they had concerns over theirmental health. Qualitative data revealed drug workers are providing mental health support to service users, but haven’t received formal training. Discussion: This is a small study limited by questionnaire design and sample size. However, it does highlight some important points. Namely, drug users remain at higher risk of suicide ideation and selfharm than general pop…

Abstract Background Online self-help interventions have proven to be effective in treating various specific mental disorders, mainly depression and anxiety. Knowledge regarding their acceptance, efficacy, and usefulness in addition to inpatient or outpatient psychotherapy is limited. Therefore, we plan to evaluate an affect-focused, transdiagnostic, psychodynamic online self-help intervention following inpatient psychotherapy for mixed diagnoses in a feasibility study to determine acceptance, satisfaction, and preliminary estimates of efficacy. Methods The intervention is based on the book "Living Like You Mean It" by Ronald J. Frederick (2009) and the Swedish adaption by Johansson and coll…

Influence of childhood adversities and defense styles on the 1-year follow-up of psychosomatic- psychotherapeutic inpatient treatment

2005

Abstract The current study explores the connection between reported sexual abuse and physical maltreatment during childhood and immature defense styles as affecting the 1-year follow-up of inpatients who had undergone psychodynamic group therapy. Early traumatization was assessed using a structured patient interview and the defense styles by means of the questionnaire on defense styles. Reduction in psychological distress and improvement in health-related quality of life formed the parameters against which success of treatment was measured. At the 1-year follow-up, the entire sample showed a distinct improvement. The effect sizes for health-related quality of life ranged from 0.82 to 1.21, …

Background Mental disorders have become a major health issue, and a substantial number of afflicted individuals do not get appropriate treatment. Web-based interventions are promising supplementary tools for improving health care for patients with mental disorders, as they can be delivered at low costs and used independently of time and location. Although psychodynamic treatments are used frequently in the face-to-face setting, there has been a paucity of studies on psychodynamic Web-based self-help interventions. Objective The objective of this study was to determine the feasibility and preliminary efficacy of a transdiagnostic affect-focused psychodynamic Web-based self-help intervention…

Manualized psychodynamic-interactional group therapy for the treatment of somatoform pain disorders.

2010

Medically unexplained and clinically significant symptoms of pain are highly prevalent in the general population. More than one third of all patients in general practices and various departments of hospitals suffer from somatoform disorders with pain being the main complaint of 70% of these patients. This treatment manual is the first disorder-specific, psychodynamically oriented treatment for these patients. Based on psychodynamic-interactional group psychotherapy, it focuses on disorder-specific aspects as well as on psychic and interpersonal problems which have resulted from adverse childhood experiences and insecure attachment. In three treatment phases comprising an “information and mo…

Surgical treatment of chronic thromboembolic pulmonary hypertension

1999

Background: Chronic thromboembolic pulmonary artery obstruction from unresolved pulmonary emboli is characterized by persistent elevation of pulmonary vascular resistance and progressive right heart dysfunction and failure. The diagnosis of chronic thromboembolic pulmonary hypertension is difficult and often missed. Medical therapy is ineffective in these patients. The prognosis is poor and depends on the degree of pulmonary hypertension. Pulmonary thromboendarterectomy has proven to be an effective and potentially curative surgical therapy for this clinical entity although less than 1000 cases have been reported in the surgical literature. Methods: The current principles of diagnosis, pati…

Septic cardiomyopathy: evidence for a reduced force-generating capacity of human atrial myocardium in acute infective endocarditis

2017

AbstractBackground:This study analyzes the myocardial force-generating capacity in infective endocarditis (IE) using an experimental model of isolated human atrial myocardium. In vivo, it is difficult to decide whether or not alterations in myocardial contractile behavior are due to secondary effects associated with infection such as an altered heart rate, alterations of preload and afterload resulting from valvular defects, and altered humoral processes. Our in vitro model using isolated human myocardium, in contrast, guarantees exactly defined experimental conditions with respect to preload, afterload, and contraction frequency, thus not only preventing confounding by in vivo determinants…
