Attachment and perceived stress in patients with ulcerative colitis, a case-control study.

WHAT IS KNOWN ON THE SUBJECT?: Ulcerative colitis (UC) is a chronic inflammatory disorder associated with high perceived psychological stress. The attachment theory provides a psychodynamic perspective to investigate the relationship between close interpersonal relationships and stress in UC. Researchers have hypothesized that the chronic illness might affect personality trait as the attachment style of patients. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: UC patients exhibit a more pronounced attachment insecurity that, in turn, resulted as a determinant of psychological stress. This study suggests that UC could determine a shift towards insecurity in the attachment style that, in turn, promotes psychological stress and increases the risk of psychopathologies. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The more accurate knowledge of attachment insecurity in patients with chronic disorders such as UC may help the nurses to face with often dysfunctional patients' styles of manifesting distress, patterns of help seeking and expectations of health professionals. The knowledge of psychopathological mechanisms in patients with UC could improve the prevention and treatment of psychological disorders in affected patients. ABSTRACT: Introduction Ulcerative colitis (UC) is a chronic disorder characterized by recurrent intestinal symptoms. The attachment theory provides a psychodynamic perspective to investigate the relationship between interpersonal relationships and stress in UC. Aim The aim of this study was to compare the attachment dimensions between UC patients and controls and to evaluate the impact of these dimensions on perceived stress in patients. Method In all, 101 patients with UC completed the attachment style questionnaire and the perceived stress questionnaire (PSQ). Clinical and psychometric parameters were added as predictor variables in a regression with the PSQ score as dependent variable. One hundred and five healthy subjects took part in the study as controls. Results Compared to controls, UC patients exhibited greater scores in relationships as secondary, need for approval and preoccupation with relationships. In UC, disease activity, confidence and preoccupation with relationships resulted predictors of perceived stress. Discussion Compared to healthy controls, UC patients exhibited more pronounced attachment insecurity that, in turn, was a significant predictor of the perceived stress. Implications for practice The knowledge of attachment insecurity may help the nurses and all health care providers to face with dysfunctional patients' styles of manifesting distress, help seeking and expectations of health professionals.

Attachment and quality of life in patients with inflammatory bowel disease.

PURPOSE: Inflammatory bowel diseases (IBD) are chronic disorders affecting psychological well-being, quality of life (QOL), social interactions, and close interpersonal relationships of patients affected. The attachment theory provides a theoretical framework to evaluate the quality of close interpersonal relationships in the context of chronic disorders. The aims of this study were to compare the attachment dimensions between IBD patients and healthy controls and to evaluate the impact of these dimensions on QOL in IBD patients. METHODS: One hundred three consecutive IBD outpatients (70 with Crohn's disease and 33 with ulcerative colitis) were recruited in the IBD Unit of the University of Bologna. They were clinically evaluated and filled out the questionnaire Short Form health survey-36 (SF-36), assessing QOL, and the attachment style questionnaire (ASQ), assessing attachment dimensions. One hundred three matched healthy subjects filled out the same questionnaires and represented the control group. RESULTS: IBD patients exhibited worst scores in the QOL measures (both physical and mental health) and in the attachment dimensions Relationships as secondary and Preoccupation with relationships. In IBD, the significant predictors of physical health were disease activity and disease type, while the significant predictors of mental health were disease activity and type, surgery, and the attachment dimensions Confidence and Preoccupation with relationships. CONCLUSIONS: Compared to controls, in IBD patients, the close interpersonal relationships are characterized by attachment insecurity that, in turn, is a significant predictor of QOL. These findings suggest plausible insights for psychological interventions in IBD patients with deterioration in QOL.

Functional magnetic resonance imaging study reveals differences in the habituation to psychological stress in patients with Crohn's disease versus healthy controls.

In patients with Crohn's disease (CD) stress is believed to increase the incidence of disease relapse. The brain processes stressful stimuli and triggers the stress-evoked responses. Habituation to stress is an adaptive process that allows minimizing these responses. We hypothesized inadequate habituation to stress in CD patients. The aim of this study was to compare the neural habituation between CD patients and controls. Twenty CD patients and eighteen controls underwent a functional magnetic resonance imaging while performing two repeated runs of a stress-evoking task. The task elicited different neural activity between the groups across runs in (1) amygdala, hippocampus, (2) insula, putamen (3) cerebellar regions, suggesting altered habituation to stress in patients. These structures regulate the neuroendocrine and autonomic stress-evoked responses that control the proinflammatory responses. The inadequate habituation to stress that we found in patients could play a role in the relationship between stress and inflammatory exacerbations in CD.

Brain functional changes in patients with ulcerative colitis: a functional magnetic resonance imaging study on emotional processing.

BACKGROUND: Ulcerative colitis (UC) is associated with psychological stress and poor emotional functioning. The neural emotional processing involves the complex integration of several cortical and subcortical brain structures. The amygdala plays a fundamental role in the neural processing of emotional stimuli and is a core structure of the brain-gut axis (BGA) that represents the anatomo-functional substrate for the bidirectional influences between emotions and gastrointestinal functions. The aim of this study was to investigate the brain emotional processing in UC patients compared to healthy people. METHODS: Ten UC patients in remission and 10 matched healthy controls underwent a functional magnetic resonance imaging (fMRI) scan while performing a task involving emotional visual stimuli. A set of negative, positive, and neutral pictures were used to study brain-related emotional responses. RESULTS: A significantly reduced blood oxygen level-dependent (BOLD) signal in UC patients relative to controls was found in the amygdala, thalamic regions, and cerebellar areas (P < 0.05 corrected for multiple comparisons). The group-related differences were detected in the brain activity in response to positive emotional stimuli. CONCLUSIONS: UC is associated with an emotional dysfunction characterized by decreased sensitivity to emotions with a positive content. The previous intestinal inflammatory activity in UC patients might have contributed to determine the functional changes of the amygdala that we found. On the other hand, the dysfunction of the amygdala may influence the course of the disease.

Gastroesophageal reflux disease (GERD) and inflammatory bowel disease (IBD): attachment styles and parental bonding.

The attachment styles and parental bonding by 64 patients (M age = 43.2 yr., SD = 13.3) with Gastroesophageal Reflux Disease (GERD) were compared with those of 64 patients (M age = 42.2 yr., SD = 13.5) with Inflammatory Bowel Disease (IBD) and 126 Healthy participants (M age = 42.2 yr., SD = 12.1). Analysis of scores on the Attachment Style Questionnaire indicated insecure attachment in both the patient and control groups. The Parental Bonding scores indicated perceptions of Affectionless Control by parents in both patient groups. In particular, the mean Father-Protection subscale scores were significantly higher for in the GERD group than in the Healthy and IBD groups.

Adult attachment and early parental experiences in patients with Crohn's disease.

BACKGROUND: Crohn's disease (CD) is a chronic, relapsing and remitting inflammatory bowel disease. The relationship of attachment to the illness is considered to be bidirectional. OBJECTIVE: The authors investigated aspects of this bidirectional relationship. METHOD: A group of 102 patients with CD and 306 healthy subjects filled out the Attachment Style Questionnaire and the Parental Bonding Instrument. RESULTS: Patients with CD exhibit a predominantly insecure attachment and perceived their parents' behaviors as characterized by low maternal care and high paternal overprotection. DISCUSSION: The evaluation of attachment style and early parental experiences in patients with CD may shed light on the bidirectional relationship between attachment and illness. These findings may confirm the bidirectional relationship between insecure attachment and chronic illness.

Parental bonding and inflammatory bowel disease.

BACKGROUND: Previous studies have shown a relationship between inflammatory bowel disease (IBD) and psychological stress. Adverse parenting is recognized as an important risk factor for the development of psychiatric disorders in adulthood. OBJECTIVE: The authors sought to further investigate this relationship by clarifying aspects of the bonding relationship in IBD patients and control subjects. METHOD: A group of 307 patients with IBD and a group of 307 healthy subjects filled out the questionnaire Parental Bonding Instrument. RESULTS: Patients with IBD perceived their parents' behaviors as characterized by low care and paternal overprotection; the category Optimal Parenting differs highly in the two samples. CONCLUSION: This study demonstrated an association between inadequate parenting and a chronic physical illness. These findings are consistent with a growing literature that links early parental experience to chronic illness.

Benign joint hypermobility syndrome: psychological features and psychopathological symptoms in a sample pain-free at evaluation1.

30 subjects with BJHS (Hypermobile) (M age = 32.3 yr., SD = 10.4) and two control groups, 25 healthy subjects (Healthy) (M age = 33.9 yr., SD = 9.3) and 30 fibromyalgic patients (Fibromyalgic) (M age = 32.2 yr., SD=9.4), were given the Symptom Checklist-90-R, the Illness Behavior Questionnaire, the Female Functional Symptoms Frequency (FFF) and the Male Functional Symptoms Frequency (MFF), derived from the DSM-III-R, evaluating functional somatic disturbances and their intensity, and the Symptom Questionnaire. The mean scores for the Hypermobile group showed significant psychological distress and increased frequency and intensity of somatic symptoms. Scores on Anxiety and Somatic Symptoms, General Hypochondriasis, Disease Conviction, Affective Disturbance, Denial, and Irritability were significantly higher in the Hypermobile than in the Healthy group. Elevated scores were found for the Fibromyalgic group on the Illness Behavior Questionnaire subscales for Psychological vs Somatic Focus, Disease Affirmation, and Discriminating Factors when compared with the Hypermobile group. Considerable emotional symptoms were detected which should not be underestimated by physicians when establishing an integrated biopsychosocial therapy.

Gastroesophageal reflux disease: alexithymia and attachment style.

Alexithymia and its relation with attachment style were evaluated in a group of 69 patients (men, M age = 46.4 yr., SD = 12.6; women, M age = 44.2 yr., SD = 14.4) affected by Gastroesophageal Reflux Disease. Two self-evaluation questionnaires were used for psychological evaluation, the 20 item Toronto Alexithymia Scale (TAS-20) and the Attachment Style Questionnaire (ASQ). The TAS-20 analysis showed that the clinical sample taken as a whole did not score in the alexithymic range. The inverse correlations between the Confidence ASQ subscale and the Difficulty Communicating Feelings TAS-20 subscale showed that communication of emotions could develop more easily within the framework of a relational context characterized by safety and confidence. In this group of patients this was represented by the referent caregiver.

Targeting of human renal tumor-derived endothelial cells with peptides obtained by phage display.

The phenotypic and molecular diversity of tumor-associated vasculature provides a basis for the development of targeted diagnostics and therapeutics. In the present study, we have developed a peptide-based targeting of human tumor endothelial cells (TEC) derived from renal carcinomas. We used a murine model of human tumor angiogenesis, in which TEC injected subcutaneously in severe combined immunodeficiency (SCID) mice organized in vascular structures connected with the mouse circulation, to screen in vivo a phage display library of random peptides. Using this approach, we identified cyclic peptides showing specific binding to TEC and not to normal human endothelial cells or to murine tumor endothelial cells. In particular, the peptide CVGNDNSSC (BB1) bound to TEC in vitro and in vivo. Using BB1 peptide conjugated with the ribosome-inactivating toxin saporin, we targeted TEC in vivo. Injection of BB1-saporin but not saporin alone or control modified BB-1ala saporin induced a selective cell apoptosis and disruption of the TEC vessel network. No increase in cell apoptosis was found in other murine organs. In conclusion, the identification of peptide sequences able to bind selectively human tumor-derived endothelial cells may represent a tool to deliver antiangiogenic or antitumor agents within the neoplastic vessels.

Color-coded automated signal intensity curves for detection and characterization of breast lesions: preliminary evaluation of a new software package for integrated magnetic resonance-based breast imaging.

OBJECTIVES: The objective of this study was to evaluate the value of a color-coded automated signal intensity curve software package for contrast-enhanced magnetic resonance mammography (CE-MRM) in patients with suspected breast cancer. MATERIALS AND METHODS: Thirty-six women with suspected breast cancer based on mammographic and sonographic examinations were preoperatively evaluated on CE-MRM. CE-MRM was performed on a 1.5-T magnet using a 2D Flash dynamic T1-weighted sequence. A dosage of 0.1 mmol/kg of Gd-BOPTA was administered at a flow rate of 2 mL/s followed by 10 mL of saline. Images were analyzed with the new software package and separately with a standard display method. Statistical comparison was performed of the confidence for lesion detection and characterization with the 2 methods and of the diagnostic accuracy for characterization compared with histopathologic findings. RESULTS: At pathology, 54 malignant lesions and 14 benign lesions were evaluated. All 68 (100%) lesions were detected with both methods and good correlation with histopathologic specimens was obtained. Confidence for both detection and characterization was significantly (P < or = 0.025) better with the color-coded method, although no difference (P > 0.05) between the methods was noted in terms of the sensitivity, specificity, and overall accuracy for lesion characterization. Excellent agreement between the 2 methods was noted for both the determination of lesion size (kappa = 0.77) and determination of SI/T curves (kappa = 0.85). CONCLUSIONS: The novel color-coded signal intensity curve software allows lesions to be visualized as false color maps that correspond to conventional signal intensity time curves. Detection and characterization of breast lesions with this method is quick and easily interpretable.

Gastroesophageal reflux disease: attachment style and parental bonding.

The attachment styles and parental bonding of 72 patients (M age= 45.3 yr., SD=13.5) suffering from Gastroesophageal Reflux Disease were compared with those of 105 healthy subjects (M age =44.9 yr., SD = 5.8). A clinical interview and two questionnaires, the Attachment Style Questionnaire and the Parental Bonding Instrument, showed that the scores on the ASQ Confidence subscale were significantly lower in the clinical group. Similar results were obtained for the Discomfort with Closeness subscale in the subsample with Pure Gastroesophageal Reflux Disease. The results indicate Insecure Attachment in the clinical sample. The results obtained from the Parental Bonding Instrument indicate that scores on the Protection Mother scale were significantly higher in the clinical subjects, suggesting a Low Care-High Protection combination (Affectiveless Control), at least for patients with pure Gastroesophageal Reflux Disease. These characteristics can be considered important factors in the tendency to somatization. The symptoms may have a paradoxically normalising function while the patient shows an emotional detachment towards intimate relationships. The illness appears to act as a bond through which the relationship with the caregivers is maintained.
