Anxiety boosts progression of prediabetes to type 2 diabetes: findings from the prospective Cooperative Health Research in the Region of Augsburg F4 and FF4 studies.

AIM: To investigate the association between anxiety symptoms and the progression from prediabetes to type 2 diabetes. METHODS: A sample of 1708 participants aged 31-82 years from the population-based Cooperative Health Research in the Region of Augsburg F4 and the follow-up Cooperative Health Research in the Region of Augsburg FF4 studies was included. Prediabetes was defined as impaired fasting glucose and/or impaired glucose tolerance, and anxiety status was measured by the generalized anxiety disorder-7 questionnaire. Newly diagnosed type 2 diabetes cases were identified after 6.5 years (11 102 person-years) and confirmed by medical records. Multivariate logistic regression analyses were employed to estimate the effect of prediabetes and anxiety on the incidence of type 2 diabetes with different levels of adjustments for potential confounders. The population attributable risk of type 2 diabetes in participants with prediabetes and anxiety was estimated. RESULTS: Prediabetes at baseline was prevalent in 247 participants, of whom 77 developed diabetes after follow-up, accounting for a progression rate of 31%. In participants with prediabetes, high anxiety was associated with a 3-fold increased risk of progression to type 2 diabetes in comparison with low anxiety, even after accounting for socio-demographic, lifestyle and metabolic risk factors (OR = 2.82, 95% CI = 0.95-8.37, P = 0.06). A significant proportion of incident type 2 diabetes was attributed to having anxiety in addition to prediabetes (attributable risk proportion: 0.52; 95% CI = 0.004-1.04, P = 0.05). CONCLUSIONS: Anxiety symptoms independently increase the progression risk of prediabetes to type 2 diabetes and should be routinely considered alongside the traditional risk factors in people with prediabetes.

Impact of generalized anxiety disorder (GAD) on prehospital delay of acute myocardial infarction patients. Findings from the multicenter MEDEA study.

BACKGROUND: Anxiety has been identified as a cardiac risk factor. However, less is known about the impact of generalized anxiety disorder (GAD) on prehospital delay during an acute myocardial infarction (AMI). This study assessed the impact of GAD on prehospital delay and delay related cognition and behavior. METHODS: Data were from the cross-sectional Munich examination of delay in patients experiencing acute myocardial infarction (MEDEA) study with a total of 619 ST-elevated myocardial infarction (STEMI) patients. Data on socio-demographic, clinical and psycho-behavioral characteristics were collected at bedside. The outcome was assessed with the Generalized Anxiety Disorder scale (GAD-7). A GAD-7 score greater than or equal to 10 indicates general anxiety disorder. RESULTS: A total of 11.47% (n = 71) MI patients suffered from GAD. GAD was associated with decreased odds of delay compared to patients without GAD (OR 0.58, 95% CI 0.35-0.96), which was more significant in women (112 vs. 238 min, p = 0.02) than in men (150 vs. 198 min, p = 0.38). GAD was highly correlated with acute anxiety (p = 0.004) and fear of death (p = 0.005). Nevertheless, the effect remained significant after controlling for these two covariates. GAD patients were more likely to perceive a higher cardiovascular risk (OR 2.56, 95% CI 1.37-4.76) in 6 months before MI, which leads to the higher likelihood of making self-decision to go to the hospital (OR 2.68, 95% CI 1.48-4.85) in the acute phase. However, GAD was also highly associated with impaired psychological well-being, stress and fatigue (p < 0.0001). CONCLUSIONS: In AMI patients, GAD was independently associated with less prehospital delay, but led to an impaired psychological state.

Sarcopenia is associated with disability status-results from the KORA-Age study.

We estimated the prevalence of sarcopenia and its impact on disability in older people. Sarcopenia was found to contribute to higher disability scores. However, our study was not able to show any influence of sarcopenia on the rate of functional decline. This directs attention to an accurate diagnosis of sarcopenia as the onset may be influenced, but its rate may not. INTRODUCTION: The objectives of this study using data from a population-based cohort were to estimate the prevalence of sarcopenia in older people in Germany and to test the hypothesis that sarcopenia is associated with disability in older adults. METHODS: Cross-sectional (n = 927) and longitudinal analyses (n = 859) of participants aged ≥65 years at baseline from southern Germany enrolled in the Cooperative Health Research in the Region Augsburg (KORA)-Age study (2009-2012). Sarcopenia was defined based on the European Working Group on Sarcopenia in Older People (EWGSOP) algorithm which includes the presence of both low muscle mass and low muscle function (strength or performance). Disability status was measured by the Health Assessment Questionnaire-Disability Index (HAQ-DI). The presence of disability was defined as HAQ-DI >0. Directed acyclic graphs (DAGs) were constructed to identify potential confounders. The effect of sarcopenia on disability was analyzed using linear mixed effect models with disability values as a continuous outcome. RESULTS: The overall prevalence of sarcopenia was 5.7% (men 4.0%, women 7.5%) and increased with age. The 3-year incidence of disability was 32.7%. After adjustment for potential confounders, presence of sarcopenia was significantly associated with higher disability scores (0.142 [confidence interval 0.029-0.254]). CONCLUSION: The prevalence of sarcopenia is consistent with estimates from other European studies using this algorithm. Our results suggest that sarcopenia can contribute to higher disability scores in older adults. However, our study was not able to show any influence of sarcopenia on the rate of functional decline using the EWGSOP diagnostic algorithm for sarcopenia. This directs attention to an accurate diagnosis of sarcopenia as the onset may be influenced, but its rate may not.

Is denial a maladaptive coping mechanism which prolongs pre-hospital delay in patients with ST-segment elevation myocardial infarction?

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.

Patients' knowledge about symptoms and adequate behaviour during acute myocardial infarction and its impact on delay time: Findings from the multicentre MEDEA Study.

OBJECTIVE: We aimed to assess whether patients' knowledge about acute myocardial infarction (AMI) has an impact on the prehospital delay-time. METHODS: This investigation was based on 486 AMI patients who participated in the cross-sectional Munich-Examination-of-Delay-in-Patients-Experiencing-Acute-Myocardial-Infarction (MEDEA) study. A modified German-version of the ACS-Response-Index Questionnaire was used. Multivariate logistic-regression models were used to identify factors associated with knowledge-level as well as the impact of knowledge-level on delay-time. RESULTS: High AMI-knowledge shortened median delay-time in men (168[92-509] vs. 276[117-1519] mins, p=0.0069), and in women (189[101-601] vs. 262[107-951]mins, p=0.34). Almost half-of-patients (n=284,58%) demonstrated high AMI-knowledge. High-knowledge were independently associated with male-gender (OR=1.47[1.17-1.85]) and General-Practitioner as a knowledge-source (OR=1.42[1.14-1.77]). Old-age (OR=0.87[0.86-0.89]) and previous AMI-history/stent-placement (OR=0.65[0.46-0.93]) were significantly associated with lower-knowledge. Although the majority (476,98%) correctly recognized at least one AMI-symptom, 69(14.2%) patients correctly identified all AMI-symptoms. Additionally, one-in-three believed that heart-attack is always accompanied with severe chest-pain. Elderly-patients and women were more likely to be less-knowledgeable about atypical-symptoms (p=0.006), present with atypical AMI-presentation (p<0.001) and subsequently experience protracted delay-times (p<0.001). CONCLUSIONS: Knowledge of AMI-symptoms remains to be substandard, especially knowledge of atypical-symptoms. Knowledge is essential to reduce delay-times, but it is not a panacea, since it is not sufficient alone to optimize prehospital delay-times.

Resilience moderates the association between chronic pain and depressive symptoms in the elderly.

BACKGROUND: Chronic pain is frequent in elderly people and, especially if widespread, associated with poor mental health. We investigated whether a resilient personality protects older adults against the adverse effects of chronic pain. METHODS: Pain status [no pain, chronic local pain (CLP) and chronic widespread pain (CWP)] was determined using the American College of Rheumatologists' criteria for widespread pain in a cross-sectional sample of 724 participants aged 68-92 years drawn from the population-based KORA-Age study in Southern Germany. Depressive symptoms and resilience were assessed via the scales GDS-15 and RS-5. The relation between pain, resilience and depressive symptoms was modelled using logistic and quantile regression. RESULTS: CLP prevalence and CWP prevalence were 57.5% and 12.3%, respectively. Confounder-adjusted logistic regression indicated a fourfold risk of depressed mood (GDS-15 ≥ 5) in CWP, vs. no pain (OR = 4.08, 95% CI 1.90-8.74). However, in quantile regression, the adverse effect of CWP was significantly attenuated by resilience when looking at the GDS-15 score lower quartile (p = 0.011) and median (p = 0.011). This effect appeared to be mainly driven by participants aged 75-84 years. Confounder adjustment reduced the effect of CLP on depressive symptoms to non-significance, and effect modification by resilience was undetectable in regression models of CLP. CONCLUSIONS: Resilience was protective in the association of CWP with depressive symptoms in this analysis. Older adults with CWP may potentially benefit from interventions supporting resilience. Prospective research should investigate the protective role of resilience in the potentially self-perpetuating relation between chronic pain and depressed affect. WHAT DOES THIS STUDY ADD?: The association of chronic widespread pain with depressive symptoms in the elderly population is attenuated by resilience.

No correlation between rates of suicidal ideation and completed suicides in Europe: analysis of 49,008 participants (55+ years) based on the Survey of Health, Ageing and Retirement in Europe (SHARE).

BACKGROUND: Little is known about country-specific variations in suicidal ideation (SID) by sex and how they correspond with completed suicide rate. Therefore, the aim of the present study was to assess variations in SID prevalence rates by sex and its correlation to completed suicide rates across European countries. METHOD: SHARE is a cross-national European survey of individuals over the age of 50 and their spouse of any age. The present study relied on wave 4 conducted in 2010-2012 including 49,008 participants aged 55 to 104years from 16 countries. SID was evaluated using a single item from the Euro-D. Data on completed suicide rates were taken from the WHO mortality database. RESULTS: Of the study population (n=49,008, 44.3% men, mean age 68.2±9.1years), a total of 4139 (8.5%, 95% CI 8.2-8.7) reported suicidal ideation within the last month. The women:men ratio in SID prevalence ranged from 1.30 in Estonia to 2.25 in Spain and Portugal. Regarding country-specific variation, the SID prevalence patterns of both men and women did not correspond to the completed suicide rates for males and females aged 55+ reported by the WHO (2013). Correlations were rather moderate in men (r=0.45) and especially weak in women (r=0.16). CONCLUSION: The study showed remarkable differences in SID prevalence by sex. The most exciting finding was that SID rates did not correspond with completed suicide rates in each country under investigation. However, the strength of these patterns substantially differs across countries. This unexpected finding need to be further evaluated.

Sex specific impact of prodromal chest pain on pre-hospital delay time during an acute myocardial infarction: Findings from the multicenter MEDEA Study with 619 STEMI patients.

BACKGROUND: Scarce evidence yields conflicting results regarding the effect of prodromal chest pain (PCP) on pre-hospital delay during an acute myocardial infarction (AMI). We aimed to assess the impact of PCP on delay. METHODS: Data was collected on 619 ST-elevated MI patients from the multicenter Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study. Patients with any PCP (which was subdivided into undefined PCP, possible and definite angina) within a year before AMI were identified using the Rose questionnaire, administered in bedside interviews. The influence of PCP and its subdivisions (all compared to no PCP) was assessed using logistic regression (with cut-offs of 2 h, 6 h, and a 4-category ordinal outcome). RESULTS: Any type of PCP was reported by men (50.6%) more than women (34.6%) (OR=1.9; 95% CI: 1.3 to 2.8; p=.001). The median delay of patients with PCP was not significantly different to delay in patients with no PCP (p=.327). Prolonged delay times were observed in women with PCPs of lesser degree of cardiac confirmation, while the opposite was observed in men. In women, possible angina was more strongly associated with delay <2 h (OR=6.8; 95% CI=2 to 23.8) than any PCP (OR=2.6; 95% CI=1.2 to 5.7). CONCLUSIONS: For men, PCPs of increasing cardiac confirmation are associated with prolonged delay. For women, PCPs of lesser cardiac confirmation are more likely to lead to prolonged delay. Future studies should investigate mediating factors.

Mitochondrial genetic variants identified to be associated with posttraumatic stress disorder.

Despite the fact that mitochondrial dysfunctions are increasingly recognized as key components in stress-related mental disorders, very little is known about the association between posttraumatic stress disorder (PTSD) and mitochondrial variants. To identify susceptibility mitochondrial genes for PTSD, we analyzed a total number of 978 mitochondrial single-nucleotide polymorphisms (mtSNPs) in a sample of 1238 individuals participating in the KORA (Cooperative Health Research in the Region of Augsburg) study. Participants were classified with 'no PTSD', 'partial PTSD' or 'full PTSD' by applying the Posttraumatic Diagnostic Scale and the Impact of Event Scale. To assess PTSD-mtSNP association while taking heteroplasmy into account, we used the raw signal intensity values measured on the microarray and applied linear regression. Significant associations were obtained between full versus no PTSD and two mtSNPs; mt8414C->T (ß=-0.954±0.06, Padjusted=0.037) located in adenosine triphosphate (ATP) synthase subunit 8 (MT-ATP8) and mt12501G->A (ß=-1.782±0.40, Padjusted=0.015) located in the NADH dehydrogenase subunits 5 (MT-ND5). Heteroplasmy for the two variants towards a larger number of the respective minor alleles increases the risk of having PTSD. NADH dehydrogenase and ATP synthase are both linked to the regulation of reactive oxygen species. Our results highlight the important role of the mitochondrial genome among the factors that contribute to the risk of PTSD. Mitochondrial genetic variants may be more important than has previously been assumed, leading to further insights regarding effects of existing medications, or even to the development of innovative treatments. As this is the first mitochondrial genome-wide association study for PTSDs, further analyses are needed to follow up on the present findings.

Health-related quality of life in women and men with type 2 diabetes: a comparison across treatment groups.

AIM: This study compares health-related quality of life (HRQL) in patients with type 2 diabetes (T2DM) across treatment groups and explores gender differences. METHODS: Four regional surveys (KORA, CARLA, SHIP, DHS) and a national survey (GNHIES98) were pooled at individual level. HRQL was assessed with the SF-12/-36v1. Linear regression models were used to assess the effect of T2DM by treatment type (no medication; oral; oral/insulin combination; insulin) on the physical (PCS-12) and mental summary score (MCS-12) and the SF-6D, controlling for age, sex, study and covariates. We also performed an explanatory analysis of single items. RESULTS: PCS-12 scores and treatment type were associated (P-value 0.006), with lowest values for insulin treatment (-4.44 vs. oral; -4.41 vs. combination). MCS-12 scores were associated with treatment type and gender (P-value <0.012), with lower scores for women undergoing oral (-4.25 vs. men) and combination treatment (-6.99 vs. men). Similar results were observed for SF-6D utilities and single items, related to mental health, social functioning, vitality and role limitation (emotional). Comorbidities were predictors of lower PCS-12 and SF-6D scores. CONCLUSIONS: T2DM treatment impacts differently on physical and mental HRQL and on women and men. Further studies of gender-specific perceptions of T2DM treatment regimens are needed.

[Gender-specific aspects of coronary heart disease]. / Geschlechtsspezifische Aspekte bei der koronaren Herzkrankheit.

The total number of deaths from cardiovascular diseases (CVD) is greater for women than for men, although the mean age at manifestation of CVD is about 10 years older. However, the annual number of cases treated for CVD in acute hospital settings in men exceeds that of women by 50 %. Remarkable gender differences exist in terms of morphological and physiological conditions (e.g. mean coronary vessel diameter; ability to adapt to protective exercise-induced myocardial hypertrophy), as well as of the frequency and clinical significance of somatic risk factors (e.g. smoking). Female body weight increases after menopause and the body shape assumes a more android fat distribution. Women report higher levels of unspecific and affective symptoms. They suffer more from anxiety and depression than men; however, the secondary impact on CVD onset may be less pronounced. The post-acute CVD course is more complicated in women, mainly because they are older and suffer more from multi-morbidity. Whilst male CVD patients aim for a rapid recovery, physical fitness and an increased life expectancy, female patients seek relief from everyday challenges, the maintenance of their independence and emotional support.

[Psychocardiology: clinically relevant recommendations regarding selected cardiovascular diseases]. / Psychokardiologie: praxisrelevante Erkenntnisse und Handlungsempfehlungen.

Psychosocial risk factors (work stress, low socioeconomic status, impaired social support, anger, anxiety and depression), certain personality traits (e.g. hostility) and post-traumatic stress disorders may negatively influence the incidence and course of multiple cardiovascular disease conditions. Systematic screening for these factors may help to adequately assess the psychosocial risk pattern of a given patient and may also contribute to the treatment of these patients. Recommendations for treatment are based on current guidelines. The physician-patient interaction should basically follow the principle of a patient centered communication and should gender and age specific aspects into consideration. Integrated biopsychosocial care is an effective, low threshold option to treat psycho-social risk factors and should be offered on a regular basis. Patients with high blood pressure may profit from relaxation programs and biofeedback procedures (however with moderate success). An individually adjusted multimodal treatment strategy should be offered to patients with coronary heart disease, heart failure and after heart surgery. It may incorporate educational tools, exercise therapy, motivational modules, relaxation and stress management programs. In case of affective comorbidity, psychotherapy may be indicated. Anti-depressant pharmacotherapy with selective serotonin reuptake inhibitors (SSRIs) in the first line should only be offered to patients with at least moderate severe depressive episodes. Psychotherapy and SSRIs, particularly sertraline, have been proven to be safe and effective with regard to improvements of the patient's quality of life. A prognostic benefit has not been clearly proven so far. Patients with an implanted cardioverter/defibrillator (ICD) should receive psychosocial support on a regular basis. Concomitant psychotherapy and/or psychopharmacotherapy (SSRIs) should be offered in case of a severe mental comorbidity. Generally, tricyclic antidepressants should be avoided in cardiac patients because of adverse side effects.

Feasibility, internal consistency and covariates of TICS-m (telephone interview for cognitive status-modified) in a population-based sample: findings from the KORA-Age study.

OBJECTIVE: Test the feasibility of the modified telephone interview for cognitive status (TICS-m) as a screening tool to detect cognitive impairment in a population-based sample of older subjects. METHODS: Data were collected from 3,578 participants, age 65-94 years, of the KORA-Age study. We used analysis of covariance to test for significant sex, age and educational differences in raw TICS-m scores. Internal consistency was analysed by assessing Cronbach's alpha. Correction for education years was undertaken, and participants were divided in three subgroups following validated cut-offs. Finally, a logistic regression was performed to determine the impact of sex on cognition subgroups. RESULTS: Internal consistency of the TICS-m was 0.78. Study participants needed approximately 5.4 min to complete the interview. Lower raw TICS-m scores were associated with male sex, older age and lower education (all p < 0.0001). After correction for education years, 2,851 (79%) had a non-impaired cognitive status (score >31). Male sex was independently associated with having a score equal to or below 27 and 31 (OR = 1.9, 95% CI 1.4-2.5 and OR = 1.5, 95% CI 1.2-1.7, respectively). CONCLUSIONS: The TICS-m is a feasible questionnaire for community-dwelling older adults with normal cognitive function or moderate cognitive impairment. Lower cognitive performance was associated with being a man, being older, and having fewer years of formal education.

[Treating ICD patients at the end of their lives: attitudes, knowledge, and behavior of doctors and patients. A critical literature analysis]. / Umgang mit ICD-Patienten an ihrem Lebensende: Einstellungen, Wissen und Verhalten von Ärzten und Patienten. Eine kritische Literaturanalyse.

BACKGROUND: The implantable cardioverter-defibrillator (ICD) is highly effective in the therapy of malign heart rhythm abnormalities. However, the ethical dilemma of harming a dying patient has received little attention. We studied the current state of knowledge and behavior of physicians and the subjective needs of ICD patients with respect to end-of-life issues. METHODS: A literature search of articles published between 8/2010 and 3/2011 in PubMed resulted in the identification of 32 reports, of which 25 met selection criteria. RESULTS: Practically no clinical institution (96% in Europe) offers routine counseling of ICD patients on end-of-life issues. In only about 25% of cases do doctors initiate a discussion on this issue with the ICD patient, of which the majority takes place during the final hours of the patient's life. Knowledge of legal aspects of ICD deactivation is insufficient in about 50% of physicians. Many physicians underestimate the impact of ICD shocks and often have unrealistic expectations about the patient's knowledge on technical aspects of the ICD device. The majority of patients are reluctant to address this topic and prefer to rely on the decision of their attending physician. CONCLUSION: Despite insufficient empirical data, findings point to a low willingness of ICD patients to confront the end-of-life issue and prefer decisions to be made by their physician. Substantial knowledge gaps of physicians may cause barriers in considering the option of deactivating the ICD.

Flattened circadian cortisol rhythm in type 2 diabetes.

INTRODUCTION: While altered cortisol concentrations have been observed in subjects with type 2 diabetes their circadian cortisol profile is unknown. PATIENTS AND METHODS: Using a cross-sectional design, we studied 63 ambulatory individuals with type 2 diabetes and 916 non-diabetic control subjects of the Cooperative Research in the Region of Augsburg (KORA)-F3 study. Circadian cortisol profiles were derived from saliva cortisol concentrations, determined on a regular weekday upon wake-up (F0), as well as ½ h (F½), 8 (F8) and 14 h (F14) after wake-up. RESULTS: Diabetic subjects exhibited a flattened circadian cortisol profile (rm-ANOVA: F[3,654]=3.41, p=0.02), with lower morning and higher afternoon and evening cortisol concentrations. CONCLUSION: We observed a flattened circadian cortisol rhythm in subjects with type 2 diabetes, providing evidence for a specific HPA system dysfunction.

[Multimorbidity and successful aging: the population-based KORA-Age study]. / Multimorbidität und erfolgreiches Altern: Ein Blick auf die Bevölkerung im Rahmen der KORA-Age-Studie.

BACKGROUND: The objective of the KORA-Age research consortium is to assess the determinants and consequences of multimorbidity in the elderly and to look into reasons for successful aging in the general public. PATIENTS AND METHODS: In the KORA-Age cohort study 9,197 persons were included who where born in the year 1943 or before and participants of previous KORA cohort studies conducted between 1984 and 2001 (KORA: Cooperative Health Research in the Region of Augsburg). The randomized intervention study KORINNA (Coronary infarct follow-up treatment in the elderly) tested a nurse-based case management program with 338 patients with myocardial infarct and included an evaluation in health economics. RESULTS: A total of 2,734 deaths were registered, 4,565 participants submitted a postal health status questionnaire and 4,127 participants were interviewed by telephone (response 76.2% and 68.9% respectively). A gender and age-stratified random sample of the cohort consisting of 1,079 persons took part in a physical examination (response 53.8%). CONCLUSION: The KORA-Age consortium was able to collect data in a large population-based sample and is contributing to the understanding of multimorbidity and successful aging.

[Psychological comorbidity and quality of life in patients with an implantable cardioverter/defribrillator (ICD)]. / Psychische Komorbidität und Lebensqualität bei Patienten mit implantierbarem Kardioverter/Defibrillator (ICD).

Currently, the method of choice for protection against sudden cardiac death for high-risk patients is ICD treatment. The CIDS study could prove a significant advantage of ICD treatment compared to amiodarone therapy. However, the survival advantages can be affected by the negative side effects of ICD therapy. The therapeutic survival function of the device is, in general, associated with a consciously experienced, at the same time completely unexpected and unprepared intracardial shock experience. Within the first year after implantation, 30-50% of patients with an ICD for secondary preventative indications experience such a shock. The average shock application frequency per year (under normal conditions) is about 2.5 shocks. The experience of one or more ICD shocks is significantly associated with a decrease in quality of life. Particularly the experiencing of five or more intracardial shocks approaches the patient's psychological resilience threshold. Partners and relatives of ICD patients are, on the other hand, often helpless with respect to the demands of and stress associated with the ICD technology. In current clinical practice, the involvement of the partners in the treatment of ICD patients is generally a coincidence and is generally not systematic or target-oriented. Improved involvement of relatives can contribute to an improved prognosis. Cardiologists caring for ICD patients should be aware of the specific psychological aspects of ICD technology, integrate these aspects into the guidance and care of patients, and be able to identify and address pathologically negative affects and crises in ICD patients.

Prevalence of chronic migraine and medication overuse headache in Germany--the German DMKG headache study.

Population-based epidemiological studies about the prevalence of chronic migraine using the 2004 International Headache Society (IHS) classification definition are rare. We analysed the data of the Deutsche Migräne und Kopfschmerz Gesellschaft headache study, which included 7417 adults in three regions of Germany, with respect to their headache. Additionally, body mass index, alcohol consumption and smoking behaviour were recorded. Using the IHS definition from 2004, chronic migraine was diagnosed in 0.2% of the population. Half of these patients also fulfilled the criteria of medication overuse headache (MOH). The distribution of migraine attacks per subject was highly skewed, with only 14% of all migraine patients having more than six migraine attacks per month. Patients with chronic migraine or MOH seem more often to be active smokers than controls without headache. A body mass index of ≥ 30 was present significantly more often in patients with MOH than in controls or in patients with episodic migraine. The skewed distribution of the numbers of attacks per patient supports the recommendation to differentiate between episodic migraine with low and high attack frequency, as is done in the classification of tension-type headache. It further suggests that migraine with high attack frequency might be biologically different. The higher prevalence of smokers and of patients with a body mass index ≥ 30 in chronic migraine or MOH supports the idea of a frontal dysfunction in these patients.

Regional variations in the prevalence of migraine and tension-type headache applying the new IHS criteria: the German DMKG Headache Study.

The prevalence of migraine and tension-type headache (TTH) varies considerably with respect to gender, age group and geographic regions. Methodological differences in the assessment and classification of cases are a major cause of this variability across studies, limiting the ability to perform true regional comparisons. We conducted three population-based studies in different German regions and assessed headache prevalence and headache characteristics in face-to-face interviews, applying standardized methods. We analysed the 6-month prevalence of migraine, TTH and their probable subtypes based on the new criteria of the International Headache Society (IHS). Among the 7417 participants in all three regions, the pooled 6-month prevalence of migraine, probable migraine, TTH and probable TTH was 6.75, 4.40, 19.86 and 11.61%, respectively. Despite the application of standardized classification methods, regional variations between 4.39 and 8.00% for migraine and 15.44 and 23.64% for TTH were observed, indicating differences in the local headache burden. Application of the new IHS criteria yielded headache categories that were not mutually exclusive, indicating a need for further discussion about the value of probable headache types in epidemiological studies.
