Psychological correlates in patients with different levels of hypertension
No full textThe evidence linking essential systemic arterial hypertension (SAH) with psychological characteristics remains equivocal. The aims of this study were to assess clinical and subclinical distress, psychosocial aspects and psychological well-being in treated hypertensive patients and to evaluate the psychosocial variables associated with higher levels of blood pressure according to guidelines for hypertension management. A consecutive series of 125 hypertensive patients were evaluated using both self- and observer-rated reliable measures. Generalized anxiety disorder, minor depression, demoralization and alexithymia were the most frequent diagnoses. Cluster analysis revealed an association of three distinct symptomatological groups such as the Anxiety-Depression, the Alexithymia and the Somatization groups, with different levels of hypertension. In particular, patients with moderate to severe hypertension were more frequently in the Anxiety-Depression and the Alexithymia groups, whereas the Somatization cluster has been shown to be associated with isolated systolic hypertension. The results provide new insight into the psychosocial characteristics among patients with different levels of SAH according to recent guidelines of the management of hypertension. They also outline the need to monitor the clinical course of hypertensive patients characterized by these specific clinical and subclinical psychological conditions
Allostatic overload in patients with atrial fibrillation
No full textAtrial fibrillation (AF) is a chronic illness complicating both mental health and quality of life. Individuals with AF have been reported to experience greater psychological distress than the general population. Nevertheless, assessment strategies did not allow to evaluate fundamental information, such as type, extent and consequences of stress. Recently, according to the clinimetric approach, Fava and colleagues have introduced specific criteria for evaluating the allostatic overload (AO) in clinical setting. It refers to a state due to the cumulative interactions of life events and chronic life stressors that, by exceeding the individual resources, may constitute a danger to health.
Our study aimed to evaluate the feasibility of this new definition of AO in a sample of 62 patients suffering from AF. Specifically, our goal was to verify if such definition of AO may discriminate AF patients at high risk for clinical psychological distress.
Results showed no differences between AF participants with and without AO in socio-demographic and health variables. Concerning psychiatric variables, patients with AO were more likely to be diagnosed with minor depression, GAD and panic disorders than subjects without AO. Also, they were more likely to suffer from DCPR syndromes of health anxiety and demoralization than AF individuals without AO.
Our findings support the hypothesis that clinimetric indexes may help physicians to identify distress manifestations and clinically relevant information more easily than diagnostic criteria do
Hostility and the clinical course of outpatients with congestive heart failure
No full textOBJECTIVE: The role of depression and quality of life on clinical outcomes of congestive heart failure (CHF) is well recognised. However, there are fewer studies investigating the prognostic role of subclinical psychological distress and well-being impairments. The aims of this study were to evaluate clinical/subclinical psychological distress and well-being in CHF outpatients, and the influence of these psychological factors on adverse cardiac events (re-hospitalisation, cardiac death), at 4-year follow-up.
DESIGN: Sixty-eight CHF outpatients underwent psychological assessment at baseline and, after 4 years, information about cardiac events was collected in 60 patients by means of clinical records.
MAIN OUTCOME MEASURES: Psychological assessment included structured clinical interview for DSM (major/minor depression), Interview for diagnostic criteria for psychosomatic research (demoralisation), symptom questionnaire, psychological well-being scales.
RESULTS: At follow-up, 39.7% of the baseline sample reported cardiovascular events (14 CHF-related re-hospitalisations and 13 cardiac deaths) and 5.9% other causes for death. Among the variables examined as potential risk factors for adverse cardiovascular outcomes, only hostility was significant, even after controlling for disease severity (hazard ratio = 2.38, 95%confidence interval: 1.04-5.45, p = .040).
CONCLUSION: In outpatients with CHF, psychological assessment should include both clinical and subclinical distress such as hostility, in order to better address psychological risk factors for cardiac outcomes
Well-being, ill-being and symptoms of atrial fibrillation
No full textObjective. The aim of this study was to compare patientswith
symptomatic and asymptomatic atrial fibrillation, in terms of
medical variables, self-rated psychological distress and well
being, and to evaluate possible correlations among these
variables.
Methods. Sixty-two outpatients with documented atrial
fibrillation (34 with symptomatic atrial fibrillation and 28
without) were evaluated by self-report instruments: the
Psychological Well being Scale (PWB) and the Symptom
Questionnaire to detect psychological distress. The two
groups were compared by means of the t-test and x2-test.
Linear regression was performed to evaluate correlations
between psychological well being and distress in patients
with symptomatic and asymptomatic atrial fibrillation.
Results. Patients with symptomatic atrial fibrillation
showed lower levels of psychological well being and
higher scores of distress than asymptomatic
participants. Only among patients with symptomatic atrial
fibrillation, all the dimensions of PWB were significantly and
negatively associated with the Symptom Questionnaire
scores.
Conclusion. These results suggest peculiar psychological
correlates in the population of patients with symptomatic
atrial fibrillation, which should be taken into account for their
psychological and clinical management
Assessing psychological factors affecting medical conditions: comparison between different proposals
No full textOBJECTIVE:
We compared the provisional Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for Somatic Symptom Disorders (SSD) and an alternative classification based on the Diagnostic Criteria for Psychosomatic Research (DCPR) as to prevalence and associations with dimensional measures of psychological distress and functioning in a population of medical patients.
METHOD:
Seventy consecutive outpatients with congestive heart failure were administered an ad hoc structured clinical interview for the identification of DSM-5 SSD, the section concerning hypochondriasis of the Structured Clinical Interview for DSM-IV, the Structured Interview for DCPR and Paykel's Clinical Interview for Depression. Subjects also completed the Symptom Questionnaire and the Psychosocial Index. Global assessment of functioning was performed with the DSM-IV Axis V.
RESULTS:
A diagnosis within DSM-5 SSD was found in 13 patients (18.5%): 61.5% of them were diagnosed with the Psychological Factors Affecting Medical Condition category. Twenty-nine patients (41.4%) were classified according to the DCPR-based proposal: illness denial, demoralization and irritable mood were the most frequent specifiers. The DCPR-based classification showed a greater number of significant associations with dimensional measures of psychological distress, global functioning and stress.
CONCLUSION:
Compared to DSM-5 SSD, the DCPR-based proposal was more sensitive in detecting psychological factors relevant to illness course and provided a better characterization of such factors. The DCPR-based proposal was also superior in identifying patients with increased psychological distress and poor psychosocial functioning
Psychological correlates of vasovagal versus medically unexplained syncope
No full textObjective
Psychiatric morbidity is quite common in vasovagal syncope (VVS), but findings are sometimes contradictory. Among patients with suspected VVS, up to 40% has a negative response to Head-Up Tilt test (HUT), the cause of syncope remaining unexplained (US). The authors evaluated and compared the psychological and psychosomatic profile in patients with positive (VVS) and negative HUT (US).
Method
A consecutive series of 67 patients with suspected VVS underwent HUT: 45 patients had a positive HUT, 22 negative. They were evaluated by means of observer- and self-rated measures.
Results
Of the total sample, 95.5% had at least one Diagnostic and Statistical Manual of Mental Disorders diagnosis or one psychosomatic syndrome, such as specific and social phobias, illness denial and demoralization. Comparing VVS and US patients, no statistical differences on diagnoses' frequencies were found. However, the US group had significantly poorer health habits, lower levels of well-being and higher psychological distress. They also reported to be more anxious, depressed and hostile. VVS patients were significantly more blood and social phobic than US patients.
Conclusion
Despite similar and remarkable observer-rated psychopathology, US patients reported higher self-perceived psychological distress than VVS patients. Psychological evaluation of patients undergoing HUT should incorporate both clinical and subclinical methods to better address syncope management
Psychological factors affecting cardiologic conditions.
No full textThere are substantial data supporting a strong relationship between cardiovascular diseases and psychological conditions. However, the criteria for scientific validation of the entities currently subsumed under the DSM-IV category of 'Psychological factors affecting a medical condition' have never been clearly enumerated and the terms 'psychological symptoms' and 'personality traits' that do not satisfy traditional psychiatric criteria are not well defined; moreover, it is difficult to measure these subtypes of distress and there is always the need for a clinical judgment. In recent years psychosomatic research has focused increasing attention on these clinical and methodological issues. Psychosocial variables that were derived from psychosomatic research were then translated into operational tools, such as Diagnostic Criteria for Psychosomatic Research; among these, demoralization, irritable mood, type A behavior are frequently detected in cardiac patients. The joint use of DSM-IV criteria and Diagnostic Criteria for Psychosomatic Research allow then to identify psychological factors that seem to affect cardiologic condition. There remains the need to further investigate if treating both clinical and subsyndromal psychological conditions can improve quality of life and reduce the risk of morbidity and mortality in these patients
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
