Abstract
Very little is known about the impact of living with non-muscle invasive bladder cancer (NMIBC). NMIBC patients' experiences of their illness-in terms of their perceptions, coping strategies and psychological wellbeing-were explored. This study describes an interpretative phenomenological analysis (IPA) of individuals' accounts of living with NMIBC while on routine surveillance for cancer recurrence. Ten individuals took part in face-to-face semi-structured interviews. Three superordinate themes were derived from the data. The first theme, Being Diagnosed and Treated for NMIBC, concerned the observation that participants considered the physical implications, timeline and practicalities of their illness of primary importance and focused less on its psychological aspects. The second theme, Grappling with the Illness, outlined the impact of the doctor-patient relationship. The final theme, 'I don't treat it as a problem. I treat it as an issue', delineated how participants managed difficult emotions in the context of the illness. Findings from this study demonstrated that participants generally found effective ways to cope with their illness and experience of ongoing surveillance, though delay of emotional responses was common. Clinical implications for healthcare professionals are outlined including the importance of high-quality communication with the urology team.

Abstract
INTRODUCTION Illness denial pertains to medical patients who do not acknowledge the presence or severity of their disease or the need of treatment. OBJECTIVE This systematic review was performed to clarify the clinical role and manifestations of illness denial, its impact on health attitudes and behavior, as well as on short- and long-term outcomes in patients with medical disorders. METHODS The systematic search according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines was conducted on PubMed, Scopus, and Web of Science. RESULTS The initial search yielded a total of 14,098 articles; 176 studies met the criteria for inclusion. Illness denial appeared to be a relatively common condition affecting a wide spectrum of health attitudes and behavior. In some cases, it may help a person cope with various stages of illness and treatment. In other situations, it may determine delay in seeking treatment, impaired adherence, and reduced self-management, leading to adverse outcomes. The Diagnostic Criteria for Psychosomatic Research (DCPR) were found to set a useful severity threshold for the condition. An important clinical distinction can also be made based on the DCPR for illness denial, which require the assessment of whether the patient has been provided with an adequate appraisal of the medical situation. CONCLUSIONS This systematic review indicates that patients with medical disorders experience and express illness denial in many forms and with varying degrees of severity. The findings suggest the need for a multidimensional assessment and provide challenging insights into the management of medical disorders.

Abstract
Alexithymia is a construct defined as the inability to differentiate between emotional experiences and bodily sensations. According to existing knowledge, alexithymia may have a major effect on the process of treatment and the outcome of the hemodialysis disease. The objective of this literature review was to determine the significance that alexithymia has for compliance and variables of clinical and mental health in the population of hemodialysis patients. For the above purpose, bibliographic databases “MEDLINE” and “Web of Science” were searched. The matrix method was used in analysis of articles. Searching both databases resulted in 248 articles. After applying exclusion and inclusion criteria, we included results of 13 articles in the literature review. The results of the search are findings regarding the prevalence and correlation of alexithymia with variables of clinical and mental health in hemodialysis patients. Alexithymia is significantly more common in the population of hemodialysis patients, and it has a negative effect on their mental and somatic health. Alexithymia levels in hemodialysis patients are more pronounced in cases where there is a greater number of comorbidities. Alexithymia is the predictor of high mortality rate in the population of hemodialysis patients, independent of other comorbidities.

Abstract
BACKGROUND The present study investigated associations between defense mechanisms and life satisfaction among North Korean refugees living in South Korea. METHODS A total of 178 North Korean refugees completed the Korean version of the Defense Style Questionnaire, a revised version of the Ways of Thinking of North Korean Defectors scale, the Center for Epidemiologic Studies-Depression Scale, and the State-Trait Anxiety Inventory. Multiple stepwise regression analysis was performed to investigate the defense mechanisms associated with North Korean refugees' life satisfaction in South Korea. RESULTS Among defense mechanisms, denial most strongly predicted higher overall and economic satisfaction among North Korean refugees living in South Korea (β = 0.145, p < 0.01; β = 0.137, p = 0.03, respectively) after controlling for age, gender, anxiety, depression, and number of traumatic events experienced. Furthermore, resignation predicted lower overall (β = -0.206, p < 0.001) and economic satisfaction (β = -0.134, p = 0.02). However, the association between resignation and life satisfaction was not significant after controlling for depression, anxiety, and number of traumatic events experienced. CONCLUSIONS Specific defense mechanisms such as high denial and low resignation were associated with life satisfaction in South Korea among North Korean refugees. Our findings suggest that refugees' psychological defense mechanisms may affect their satisfactory resettlement.

Comparisons of fatigue between dialysis modalities: A cross-sectional study. PLoS One 2021; 16:e0246890.

Abstract
Background Fatigue is one of the most frequent complications in dialyzed patients and is associated with poorer patient outcomes. Multiple factors are reported to be associated with fatigue development. Of them, the impacts of dialysis modalities remain unknown. Methods A total of 194 dialysis patients (mean age, 61±11 years; 134 males; modalities included hemodialysis (HD) in 26, online hemodiafiltration (HDF) in 74, peritoneal dialysis (PD) in 68, and combined therapy with PD and HD in 26 cases) were recruited for this cross-sectional study. Fatigue was assessed using the Profile of Mood States (POMS), a Visual Analogue Scale (VAS), and our original scale of fatigue, and depression was assessed by the Beck Depression Inventory-second edition (BDI-II). Our original scale of fatigue was administered both on dialysis and dialysis-free days to patients on HD and online HDF. Results The scores of the POMS, VAS, and our original scale were weakly but significantly inter-related (rho = 0.58, P<0.01; rho = 0.47, P<0.01, and rho = 0.42, P<0.01 between POMS and VAS, POMS and our original scale for fatigue, and VAS and our original scale for fatigue, respectively). The scores of these 3 tests showed no significant differences among the 4 modalities. On multivariate analysis, age, body mass index, creatinine, and employment status were associated with the presence or severity of fatigue, whereas dialysis modality was not. A similar result was obtained in 122 patients without depression. The prevalence of fatigue by our original scale was significantly lower on dialysis-free days than on dialysis days in patients on HD and online HDF. Conclusions The results suggest that there is no significant association between different dialysis modalities including HD, online HDF, PD and combined therapy with PD and HD and the prevalence or severity of fatigue.

Abstract
Background The function of emotions, beginning from the proto-emotions, is the adaptation to the environment. This is based on the Homeorhesis, the equilibrium due to the adaptive operation of excitement and the dissipation of emotions. The object relations of the participants foresee the practice of defense mechanisms in a continuum that goes from the consciousness to the oneiric activities. The predominant and maladaptive use of defense mechanisms in the psychosomatic phenomenology, can be identified with deficits in emotional awareness, with the impossibility to manage excitement and dissipation of emotions foreseen by the oneiric phenomena. Methods The observation group is composed by 140 participants, 56 males (43%) and 84 females (57%),with pathological-functional disorders of psychosomatic domain. The study had been conducted with the use of measures related to the conscious defense of suppression (Suppression Mental Questionnaire), to the emotional awareness linked to the psychosomatic phenomena (Diagnostic Criteria for Psychosomatic Research Structured Interview-DCPR-SI) and to the states of perturbation and conservation of oneiric activities (The Manheim Dream Questionnaire-MADRE). Results Significant inverse correlations emerged among rationalization, repressive function and illness Denial, as for the suppression mental questionnaire factors and irritable mood, but for Regression in the service of the Ego; inverse and significant correlations emerged among suppression, repressive function, rationalization and gastrointestinal psychosomatic outcomes and among suppression, repression and cardiological psychosomatic outcomes. Regarding alexithymia, a positive correlation emerged with rationalization and inverse with Regression in the service of the Ego. Positive correlations emerged between illness denial and overall emotional tone, for disease phobia and meaningfulness and for cardiological psychosomatic outcomes and nightmare distress and recurring nightmares. Conclusion The study of such outcomes due to a prevalent defensive style based on suppression, suggest the identification of a key phenomenon, which translates into maladjustment that goes from functional disorders to parasomnia. The bridge established by the obfuscation of conscious contents until the manifestations of disturbance of ancient activities such as oneiric ones, expresses the need to transform an emotional maladaptive style, in line with classic literature and the current state of art.

Abstract
Background The highly burdensome effects of kidney failure and its management impose many life-altering changes on patients. Better understanding of successful coping strategies will inform patients and help health care providers support patients’ needs as they navigate these changes together. Methods A qualitative, cross-sectional study involving semi-structured telephone interviews including open- and closed-ended questions, with 179 U.S. patients with advanced chronic kidney disease (CKD), either not yet on dialysis ([CKD-ND], n = 65), or on dialysis (hemodialysis [HD], n = 76; or peritoneal dialysis [PD], n = 38) recruited through social media and in-person contacts from June to December 2013. Themes identified through content analysis of interview transcripts were classified based on the Coping Strategies Index (CSI) and compared across groups by demographics, treatment modality, and health status. Results Overall, more engagement than disengagement strategies were observed. “Take care of myself and follow doctors’ orders,” “accept it,” and “rely on family and friends” were the common coping themes. Participants often used multiple coping strategies. Various factors such as treatment modality, time since diagnosis, presence of other chronic comorbidities, and self-perceived limitations contributed to types of coping strategies used by CKD patients. Conclusions The simultaneous use of coping strategies that span different categories within each of the CSI subscales by CKD patients reflects the complex and reactive response to the variable demands of the disease and its treatment options on their lives. Learning from the lived experience of others could empower patients to more frequently use positive coping strategies depending on their personal context as well as the stage of the disease and associated stressors. Moreover, this understanding can improve the support provided by health care systems and providers to patients to better deal with the many challenges they face in living with kidney disease.

Abstract
Objective. The association between Fibromyalgia Syndrome (FMS) and childhood maltreatment and adversity has frequently been proposed but limited data exists regarding the transcultural nature of this association. Methods. 75 Israeli FMS patients and 23 Rheumatoid Arthritis (RA) patients were compared. Childhood maltreatment was assessed by the Childhood Trauma Questionnaire (CTQ) and potential depressive and anxiety disorders were assessed by the Patient Health Questionnaire-4. FMS severity was assessed by the Widespread Pain Index (WPI), the Symptom Severity Score (SSS), and the FIQ. PTSD was diagnosed according to the DSM IV. RA severity was assessed by the RA Disease Activity Index. Health status was assessed by the SF-36. Results. Similar to reports in other countries, high levels of self-reported childhood adversity were reported by Israeli FMS patients. PTSD was significantly more common among FMS patients compared with RA patients, as well as childhood emotional abuse and physical and emotional neglect. Levels of depression and anxiety were significantly higher among FMS patients. Conclusion. The study demonstrated the cross cultural association between FMS and childhood maltreatment, including neglect, emotional abuse, and PTSD. Significant differences were demonstrated between FMS patients and patients suffering from RA, a model of an inflammatory chronic rheumatic disease.

Is denial a maladaptive coping mechanism which prolongs pre-hospital delay in patients with ST-segment elevation myocardial infarction? J Psychosom Res 2016; 91:68-74. [PMID: 27894465 DOI: 10.1016/j.jpsychores.2016.10.008] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2016] [Revised: 10/19/2016] [Accepted: 10/20/2016] [Indexed: 11/24/2022]
Abstract
OBJECTIVE During an acute myocardial infarction, patients often use denial as a coping mechanism which may provide positive mood regulating effects but may also prolong prehospital delay time (PHD). However, empirical evidences are still sparse. METHODS This cross-sectional study included 533 ST-elevated myocardial infarction (STEMI) patients from the Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study. Data on sociodemographic, clinical and psycho-behavioral characteristics were collected at bedside. The outcome was assessed using the Cardiac Denial of Impact Scale (CDIS) with the median split as cutoff point. A total of 206 (41.8%) STEMI patients were thus classified as deniers. RESULTS Deniers were less likely to suffer from major depression (p=0.04), anxiety (p=0.01) and suboptimal well-being (p=0.01) compared to non-deniers during the last six months prior to STEMI. During STEMI, they were less likely to perceive severe pain strength (p=0.04) and racing heart (p=0.02). Male deniers were also less likely to perceive shortness of breath (p=0.03) and vomiting (p=0.01). Denial was not associated with overall delay time. However, in the time window of 3 to 24h, denial accounted for roughly 40min extra delay (356 vs. 316.5min p=0.02 n=196). CONCLUSIONS Denial not only contributes to less suffering from acute heart related symptoms and negative affectivity but also leads to a clinically significant delay in the prevalent group.

Abstract
OBJECTIVES The Coping Strategies Inventory-Short Form (CSI-SF) measures four coping strategies based on 16 items: 4 items each indicating problem- vs. emotion-focused engagement or disengagement. Here we provide the first assessment of reliability and construct validity of the CSI-SF among hemodialysis patients across 13 countries. METHODS The CSI-SF was completed by patients in 9 languages in phase 4 of the Dialysis Outcomes and Practice Patterns Study (2009-11). Cronbach's alpha was used to assess internal consistency. Exploratory and confirmatory factor analyses were applied to assess the factor structure of the CSI-SF by country and language. CSI-SF data were analyzed from 7201 patients (60% male; median age 62.5 [range 18-96] years). RESULTS Good internal consistency (α=0.56-0.80) was seen for three scales in English (US, UK, Canada, Australia, New Zealand), German, and Swedish versions. The fourth scale was internally consistent if two items were dropped. In these countries, both exploratory and confirmatory factor analyses indicated a factor structure consistent with the four CSI-SF scales. Other language versions showed a factor structure inconsistent with these four scales. CONCLUSION The slightly modified English, German, and Swedish versions of the CSI-SF are reliable and valid instruments for measuring coping strategies in hemodialysis patients.
