Factors associated with the onset of major depressive disorder in adults with type 2 diabetes living in 12 different countries: results from the INTERPRET-DD prospective study.

AIMS: To examine the factors that are associated with changes in depression in people with type 2 diabetes living in 12 different countries. METHODS: People with type 2 diabetes treated in out-patient settings aged 18-65 years underwent a psychiatric assessment to diagnose major depressive disorder (MDD) at baseline and follow-up. At both time points, participants completed the Patient Health Questionnaire (PHQ-9), the WHO five-item Well-being scale (WHO-5) and the Problem Areas in Diabetes (PAID) scale which measures diabetes-related distress. A composite stress score (CSS) (the occurrence of stressful life events and their reported degree of 'upset') between baseline and follow-up was calculated. Demographic data and medical record information were collected. Separate regression analyses were conducted with MDD and PHQ-9 scores as the dependent variables. RESULTS: In total, there were 7.4% (120) incident cases of MDD with 81.5% (1317) continuing to remain free of a diagnosis of MDD. Univariate analyses demonstrated that those with MDD were more likely to be female, less likely to be physically active, more likely to have diabetes complications at baseline and have higher CSS. Mean scores for the WHO-5, PAID and PHQ-9 were poorer in those with incident MDD compared with those who had never had a diagnosis of MDD. Regression analyses demonstrated that higher PHQ-9, lower WHO-5 scores and greater CSS were significant predictors of incident MDD. Significant predictors of PHQ-9 were baseline PHQ-9 score, WHO-5, PAID and CSS. CONCLUSION: This study demonstrates the importance of psychosocial factors in addition to physiological variables in the development of depressive symptoms and incident MDD in people with type 2 diabetes. Stressful life events, depressive symptoms and diabetes-related distress all play a significant role which has implications for practice. A more holistic approach to care, which recognises the interplay of these psychosocial factors, may help to mitigate their impact on diabetes self-management as well as MDD, thus early screening and treatment for symptoms is recommended.

Longitudinal associations between depression and diabetes complications: a systematic review and meta-analysis.

To conduct a systematic review and meta-analysis of longitudinal studies assessing the bi-directional association between depression and diabetes macrovascular and microvascular complications. Embase, Medline and PsycINFO databases were searched from inception through 27 November 2017. A total of 4592 abstracts were screened for eligibility. Meta-analyses used multilevel random/mixed-effects models. Quality was assessed using the Newcastle-Ottawa scale. Twenty-two studies were included in the systematic review. Sixteen studies examined the relationship between baseline depression and incident diabetes complications, of which nine studies involving over one million participants were suitable for meta-analysis. Depression was associated with an increased risk of incident macrovascular (HR = 1.38; 95% CI: 1.30-1.47) and microvascular disease (HR = 1.33; 95% CI: 1.25-1.41). Six studies examined the association between baseline diabetes complications and subsequent depression, of which two studies involving over 230 000 participants were suitable for meta-analysis. The results showed that diabetes complications increased the risk of incident depressive disorder (HR = 1.14; 95% CI: 1.07-1.21). The quality analysis showed increased risk of bias notably in the representativeness of selected cohorts and ascertainment of exposure and outcome. Depression in people with diabetes is associated with an increased risk of incident macrovascular and microvascular complications. The relationship between depression and diabetes complications appears bi-directional. However, the risk of developing diabetes complications in depressed people is higher than the risk of developing depression in people with diabetes complications. The underlying mechanisms warrant further research.

Prevalence and correlates of depressive disorders in people with Type 2 diabetes: results from the International Prevalence and Treatment of Diabetes and Depression (INTERPRET-DD) study, a collaborative study carried out in 14 countries.

AIMS: To assess the prevalence and management of depressive disorders in people with Type 2 diabetes in different countries. METHODS: People with diabetes aged 18-65 years and treated in outpatient settings were recruited in 14 countries and underwent a psychiatric interview. Participants completed the Patient Health Questionnaire and the Problem Areas in Diabetes scale. Demographic and medical record data were collected. RESULTS: A total of 2783 people with Type 2 diabetes (45.3% men, mean duration of diabetes 8.8 years) participated. Overall, 10.6% were diagnosed with current major depressive disorder and 17.0% reported moderate to severe levels of depressive symptomatology (Patient Health Questionnaire scores >9). Multivariable analyses showed that, after controlling for country, current major depressive disorder was significantly associated with gender (women) (P<0.0001), a lower level of education (P<0.05), doing less exercise (P<0.01), higher levels of diabetes distress (P<0.0001) and a previous diagnosis of major depressive disorder (P<0.0001). The proportion of those with either current major depressive disorder or moderate to severe levels of depressive symptomatology who had a diagnosis or any treatment for their depression recorded in their medical records was extremely low and non-existent in many countries (0-29.6%). CONCLUSIONS: Our international study, the largest of this type ever undertaken, shows that people with diabetes frequently have depressive disorders and also significant levels of depressive symptoms. Our findings indicate that the identification and appropriate care for psychological and psychiatric problems is not the norm and suggest a lack of the comprehensive approach to diabetes management that is needed to improve clinical outcomes.

Correlates of psychological outcomes in people with diabetes: results from the second Diabetes Attitudes, Wishes and Needs (DAWN2(™) ) study.

AIMS: To assess country- and individual-level correlates of psychological outcomes, and differences among countries in the associations of individual characteristics with psychological outcomes among adults with diabetes. METHODS: The second Diabetes Attitudes, Wishes and Needs (DAWN2(™) ) study assessed self-reported characteristics of people with diabetes in 17 countries, including 1368 adults with Type 1 diabetes and 7228 with Type 2 diabetes. In each country, a sample of 500 adults, stratified by diabetes type and treatment, completed a questionnaire incorporating the validated WHO-5 wellbeing index, the WHOQOL-BREF, and the five-item Problem Areas in Diabetes Scale, as well as the newly developed Diabetes Impact on Life Dimensions that assessed impact ranging from very positive to very negative, with no impact as the midpoint. Multilevel regression analyses identified significant (P < 0.05) independent correlates of psychological outcomes. RESULTS: There were significant variations in all outcomes across countries before adjustment for individual-level factors; adjustment reduced between-country disparities. Worse psychological outcomes were associated with more complications, incidence of hypoglycaemia, hypoglycaemic medication, perceived burden of diabetes, family conflict and experience of discrimination. Better psychological outcomes were associated with higher self-rated health, greater access to diabetes education and healthcare, and more psychosocial support from others. The associations of many factors with the outcomes were mediated by modifiable factors. The association of all factors with the outcomes varied across (interacted with) countries, highlighting the need for country-specific analyses. CONCLUSIONS: Improvements in modifiable risk factors (reductions in burden and increases in support) may lead to better psychological outcomes in adults with diabetes.

The INTERPRET-DD study of diabetes and depression: a protocol.

AIM: People with diabetes are at an increased risk of developing depression and other psychological disorders. However, little is known about the prevalence, correlates or care pathways in countries other than the UK and the USA. A new study, the International Prevalence and Treatment of Diabetes and Depression Study (INTERPRET-DD) aims to address this dearth of knowledge and identify optimal pathways to care across the globe. METHOD: INTERPRET-DD is a 2-year longitudinal study, taking place in 16 countries' diabetes outpatients' facilities, investigating the recognition and management of depressive disorders in people with Type 2 diabetes. Clinical interviews are used to diagnose depression, with clinical and other data obtained from medical records and through patient interviews. Pathways to care and the impact of treatment for previously unrecognized (undocumented) depression on clinical outcomes and emotional well-being are being investigated. RESULTS: Initial evidence indicates that a range of pathways to care exist, with few of them based on available recommendations for treatment. Pilot data indicates that the instruments we are using to measure both the symptoms and clinical diagnosis of depression are acceptable in our study population and easy to use. CONCLUSIONS: Our study will increase the understanding of the impact of comorbid diabetes and depression and identify the most appropriate (country-specific) pathways via which patients receive their care. It addresses an important public health problem and leads to recommendations for best practice relevant to the different participating centres with regard to the identification and treatment of people with comorbid diabetes and depression.

Towards a cognitive model of hallucinations in the course of alcohol dependence? A source monitoring-based pilot study.

BACKGROUND: We investigated whether source-monitoring deficits (here a discrimination between imagined and performed actions) underlie hallucinations among patients with a history of hallucinations in the course of their alcohol dependence. METHOD: We assessed 29 patients with alcohol dependence who had no history of hallucinations during their course of alcoholism and 29 patients with a history of at least one episode of hallucinations of any modality during their course of alcohol dependency. The control group consisted of 24 healthy participants. Participants were assessed with an action memory task. Simple actions were presented to the participants verbally or non-verbally. Some actions were performed physically and others were imagined. In the recognition phase, participants were asked whether the action was presented verbally or non-verbally (action presentation type discrimination) and whether the action was performed or imagined (self-monitoring). A confidence score related to self-monitoring responses was also obtained. RESULTS: Alcoholics with a history of hallucinations misremembered imagined actions as perceived ones more frequently than patients without hallucinations, but not the reverse. Only patients with a history of hallucinations committed more errors of this type than healthy subjects. There were no group differences regarding discrimination between an action presentation type. Both clinical groups committed errors with a higher degree of confidence than healthy subjects. CONCLUSIONS: Our results tentatively suggest that a specific type of source-monitoring deficit (i.e., confusing imagery with reality) may be involved in the hallucinations in patients with alcohol dependence. The findings are discussed in the light of a transdiagnostic approach to hallucinations.

Diabetes Attitudes, Wishes and Needs second study (DAWN2™): cross-national benchmarking of diabetes-related psychosocial outcomes for people with diabetes.

AIMS: The second Diabetes Attitudes, Wishes and Needs (DAWN2) study aimed to assess psychosocial outcomes in people with diabetes across countries for benchmarking. METHODS: Surveys included new and adapted questions from validated questionnaires that assess health-related quality of life, self-management, attitudes/beliefs, social support and priorities for improving diabetes care. Questionnaires were conducted online, by telephone or in person. RESULTS: Participants were 8596 adults with diabetes across 17 countries. There were significant between-country differences for all benchmarking indicators; no one country's outcomes were consistently better or worse than others. The proportion with likely depression [WHO-5 Well-Being Index (WHO-5) score ≤ 28] was 13.8% (country range 6.5-24.1%). Diabetes-related distress [Problem Areas in Diabetes Scale 5 (PAID-5) score ≥ 40] was reported by 44.6% of participants (17.2-67.6%). Overall quality of life was rated 'poor' or 'very poor' by 12.2% of participants (7.6-26.1%). Diabetes had a negative impact on all aspects investigated, ranging from 20.5% on relationship with family/friends to 62.2% on physical health. Approximately 40% of participants (18.6-64.9%) reported that their medication interfered with their ability to live a normal life. The availability of person-centred chronic illness care and support for active involvement was rated as low. Following self-care advice for medication and diet was most common, and least common for glucose monitoring and foot examination, with marked country variation. Only 48.8% of respondents had participated in diabetes educational programmes/activities to help manage their diabetes. CONCLUSIONS: Cross-national benchmarking using psychometrically validated indicators can help identify areas for improvement and best practices to drive changes that improve outcomes for people with diabetes.

Short-form measures of diabetes-related emotional distress: the Problem Areas in Diabetes Scale (PAID)-5 and PAID-1.

AIMS/HYPOTHESIS: We wanted to identify a five-item short form of the Problem Areas in Diabetes Scale and a single-item measure for rapid screening of diabetes-related emotional distress. METHODS: Using an existing database of 1,153 patients with diabetes, we conducted a principal-components analysis to identify a set of five items and then conducted a reliability analysis and validity checks. From those five items, we identified the item with the strongest psychometric properties as a one-item screening tool. RESULTS: We identified a reliable and valid short version of the Problem Areas in Diabetes Scale (PAID) comprising five of the emotional-distress questions of the full PAID items (PAID-5, with items 3, 6, 12, 16, 19). The PAID-5 has satisfactory sensitivity (94%) and specificity (89%) for recognition of diabetes-related emotional distress. We also identified a one-item screening tool, the PAID-1 (Question 12: Worrying about the future and the possibility of serious complications), which has concurrent sensitivity and specificity of about 80% for the recognition of diabetes-related emotional distress. CONCLUSIONS/INTERPRETATION: The PAID-5 and PAID-1 appear to be psychometrically robust short-form measures of diabetes-related emotional distress.

Serious diabetes-specific emotional problems in patients with type 2 diabetes who have different levels of comorbid depression: a Polish study from the European Depression in Diabetes (EDID) Research Consortium.

OBJECTIVE: Depression is a common psychiatric problem in patients with type 2 diabetes (DM2). A common view is that the burden of having DM2 contributes to the development of depression in DM2. Aim of the present study was to compare the levels of diabetes-specific emotional problems of DM2 patients with diagnosed depression with those with a subclinical form of depression and those without depression. METHODS: A cross-sectional study was conducted in 101 DM2 patients (51 men and 50 women, mean age = 63,17; SD = 10,74) who completed a standardized, structured psychiatric diagnostic interview (MINI), the Beck Depression Inventory, the Hamilton Depression Rating Scale as well as the Problem Areas in Diabetes (PAID) scale (a 20-item measure, with an overall scale measuring diabetes-related emotional distress and four subscales [negative emotions, treatment-related problems, food-related problems, lack of social support]). RESULTS: A depression diagnosis was made in 35% (n = 35) of the participants, 24% (n = 24) had a subclinical form of depression, 42% (n = 42) were not diagnosed with any kind of depressive disorder. Diabetes-specific emotional problems were most common in DM2 patients with a depressive disorder (significantly highest PAID score: 39) compared to patients with subclinical depression or no depression. In the group of non-depressed patients, only 14% agreed to have four or more (somewhat) serious diabetes-specific problems. In those with subclinical depression, this percentage was 42% and in those with a depressive disorder 49% (P < 0.001). CONCLUSIONS: Diabetes-related emotional problems are particularly common among DM2 patients with comorbid clinical depression and to a lesser extent in patients with subclinical depression, compared to non-depressed DM2 patients. Male diabetes patients with a depressive disorder are particularly vulnerable to develop high levels of diabetes-specific emotional distress. Major differences between the three groups mainly concern the diabetes-specific problems connected with the illness.

Effect of intravenous immunoglobulin on cerebellar ataxia and neuropathic pain associated with celiac disease.

BACKGROUND: Cerebellar syndrome and small fiber neuropathy may complicate celiac disease (CD) and may be resistant to a strict gluten-free diet. METHODS: Case series. RESULTS: We report three patients with biopsy-proven CD who developed cerebellar ataxia and neuropathic pain despite strict adherence to a gluten-free diet. A small fiber neuropathy was suggested by skin biopsy findings in two patients. All patients' symptoms, including small fiber neuropathy symptoms, responded to treatment with intravenous immunoglobulin (IVIG). Discontinuation of IVIG in two patients resulted in worsened ataxia that reversed after resumption of IVIG. CONCLUSION: Intravenous immunoglobulin may be effective in treating cerebellar ataxia and small fiber neuropathy associated with CD, suggesting an immune pathogenesis. Further prospective, controlled studies are necessary to determine the long-term response to IVIG or other immunomodulation therapy.

Monitoring of scoliosis surgery with epidurally recorded motor evoked potentials (D wave) revealed false results.

OBJECTIVE: To elucidate the mechanism behind D wave amplitude changes after surgical correction of scoliosis. METHODS: We collected D wave and muscle MEP data from 93 patients (78 female, 15 male, age range 4-19 years, mean age 15.9 years), who underwent surgical correction of scoliosis. D waves were recorded via a catheter electrode inserted epidurally through the flavectomy. Muscle MEPs from lower limb muscles were also recorded. Muscle MEPs/D wave were elicited by short trains/single transcranial electrical stimuli. SEPs were elicited through bilateral percutaneous stimulation of the tibial nerves at the ankle and an averaged response from 100 to 200 single sweeps were recorded over the scalp at Cz'/Fz. In addition, we analyzed intraoperatively obtained X-ray images of the spine in 9 patients and preoperative spinal MRI in two of those nine. RESULTS: After surgical correction of scoliosis in 25 of 93 (27%) patients, the D wave amplitude changed by more than 20% of its baseline value. A decremental change occurred in 21 (84%) and an incremental change in 4 (16%) patients. D wave decrements of more than 50% were observed in 5 patients without significant SEP changes in any of these cases. In 9 patients, intraoperatively obtained X-rays of the spine (before and after correction of spine curvature) showed no catheter displacement. Muscle MEPs did not change and postoperative sensory-motor status was normal. In 2 patients, preoperative MRI revealed displacement of the spinal cord towards the concave side of the scoliotic curvature. CONCLUSIONS: During scoliosis surgery, D wave amplitude changes should be interpreted cautiously until the definitive cause(s) of these changes are found. One possible mechanism to explain D wave changes during scoliosis correction could involve rotation of the spinal cord within the spinal canal, and the relative position of the epidural recording catheter (ERC). Rotation of the spinal cord after correction of scoliosis could introduce a new relationship between the ERC and the corticospinal tracts (CTs). Due to high incidence of false D wave amplitude changes we suggest that this methodology should not be used to assess the functional integrity of the CTs during scoliosis surgery. SIGNIFICANCE: This study provides new insight into the methodology of D wave monitoring as well as strong evidence of a high incidence of false positive results using D wave monitoring during surgical correction of scoliosis.

Alexithymia in schizophrenia: an exploratory study.

This study assessed a relationship between alexithymia and schizophrenia suggested by reports based on small samples of patients. Here, 50 outpatients with a diagnosis of paranoid schizophrenia were compared with 50 pair-matched healthy subjects. Alexithymia was measured by the Polish version of the Toronto Alexithymia Scale-20. The mean total score was significantly higher in the schizophrenia group (M = 52.3, SD = 13.47) than in the healthy controls (M = 45.8, SD = 11.39, p < .02). This replicates earlier findings showing that a group of patients with paranoid schizophrenia have higher scores on alexithymia scales than healthy controls. There seems a need for a comprehensive examination of relations between alexithymia and other concepts denoting pathology of affect in schizophrenia.

[A map of delusional world according to Zdzislaw Bizon]. / Mapa swiata urojeniowego wedlug Zdzislawa Bizonia.

The paper describes an instrument for presentation of content of delusions, which thanks to its synthetic graphic form, leads to improved systematization and understanding of delusional beliefs.

Mental organization according to the metabolism of information model and its mathematical description.

This paper outlines the concept of information metabolism, based on the structural organization of the biological cell. It was considered a model of states of consciousness (Kokoszka, 1993b) and human experiences (Kokoszka, 1999) reported earlier. The improved version of the graphical model is presented along with its preliminary description in the terms of dynamic systems. The possible application of the model to the design of artificial networks and into psychotherapeutic diagnosis discussed.

[Bizon's method of social network and social support assessment: description of the method and its application]. / Ocena otoczenia i oparcia spolecznego wedlug Zdzislawa Bizonia. Opis metody i jej zastosowania.

The development of the social network and social support assessment method designed by Bizon is concisely outlined. The final version of the measurement method is described and all its components are presented in the appendix. It consists of the Interview Questionnaire, including Social Support Inventory, the Map of Social Network, the List of Social Network, Table of the data coding and Questionnaire of Demographic Data. The main studies with this instrument are reviewed. They indicate that Bizon's method is a helpful diagnostic tool and has some advantages in comparison with similar methods applied in the studies of social support.

[Psychological factors in psoriasis: review of literature]. / Czynniki psychiczne w luszczycy--przeglad pismiennictwa.

Psoriasis is an inflammatory and proliferative disease, which is seen in most classifications of psychocutaneous disorders as being mainly due to genetic and environmental factors. Over decades of observation, physicians and patients have learned that it's course is strongly influenced by psychological stress. Review of literature shows, however, that this relationship is multifactorial. Psoriasis itself may cause depression as a stigmatizing disease. Also there is evidence that depression and anxiety disorders can be the cause of psoriasis. Because of this fact, additional treatment with psychotherapy and/or medication may be advisable and worth further exploration.

Dynamic systems theory approach to consciousness.

The review of the main existing approaches to consciousness in the literature indicates that consciousness is multileveled and that humans have an ability to experience a wide range of its various states. The common views of the main approaches to consciousness are identified and considered in a three-dimensional model of states of consciousness developed by Kokoszka. This model is then described and discussed using a mathematical terms of dynamic systems theory. Since mathematics is an accepted tool for the description of the physical world, the congruence of psychological and mathematical models is understood as a meaningful support to the psychological one. Connections of the models with artificial neural networks and some applications in psychology are considered.

Preliminary evidence for diurnal fluctuations in visual imagery.

In a repeated measures design, the Vividness of Visual Imagery Questionnaire (VVIQ; Marks, 1973) was administrated to 10 participants each half hour in a single day between 8:00 and 20:00. The questionnaire was also administrated on four consecutive days following the original administration at 8:00, 14:00 and 20:00. These results were then fitted to a model with the superposition of two cosinusoidal functions. An analysis of the results suggested the coexistence of ultradian and circadian cycles in the determination of the vividness of visual imagery.

Information metabolism as a model of human experiences.

This paper presents Kepinski's concept of "information metabolism", which attempts to describe processing of the information as an analogy of energy metabolism. It is a biological model based upon the structural organization of the cell. The following terms: control center, boundaries, functional structures, centers of elimination and centers of energy are considered here. The model is complementary to computational models, which are helpful in research and theoretical studies, but not useful in interpersonal contacts. The model of information metabolism aims at explanation of relations between psychological and somatic processes and helps in understanding of psychotherapeutic processes.

Defense mechanisms in alexithymia.

The Polish version of the Toronto Alexithymia Scale-20 and Defense Mechanisms Questionnaire were completed by 387 university students. Scores on alexithymia correlate significantly with scores on the whole group of 12 immature defenses (Pearson r = .39, p < .001) and with scores on such individual immature defense mechanisms as Autistic Fantasy (r = .39), Somatization (r = .37), Projection (r = .32), and Displacement (r = .32). These results support other findings indicating that alexithymia is significantly associated with immature ego defenses.
