Intima-media thickness at the near or far wall of the common carotid artery in cardiovascular risk assessment.

Aims: Current guidelines recommend measuring carotid intima-media thickness (IMT) at the far wall of the common carotid artery (CCA). We aimed to precisely quantify associations of near vs. far wall CCA-IMT with the risk for atherosclerotic cardiovascular disease (CVD, defined as coronary heart disease or stroke) and their added predictive values. Methods and results: We analysed individual records of 41 941 participants from 16 prospective studies in the Proof-ATHERO consortium {mean age 61 years [standard deviation (SD) = 11]; 53% female; 16% prior CVD}. Mean baseline values of near and far wall CCA-IMT were 0.83 (SD = 0.28) and 0.82 (SD = 0.27) mm, differed by a mean of 0.02 mm (95% limits of agreement: -0.40 to 0.43), and were moderately correlated [r = 0.44; 95% confidence interval (CI): 0.39-0.49). Over a median follow-up of 9.3 years, we recorded 10 423 CVD events. We pooled study-specific hazard ratios for CVD using random-effects meta-analysis. Near and far wall CCA-IMT values were approximately linearly associated with CVD risk. The respective hazard ratios per SD higher value were 1.18 (95% CI: 1.14-1.22; I² = 30.7%) and 1.20 (1.18-1.23; I² = 5.3%) when adjusted for age, sex, and prior CVD and 1.09 (1.07-1.12; I² = 8.4%) and 1.14 (1.12-1.16; I²=1.3%) upon multivariable adjustment (all P < 0.001). Assessing CCA-IMT at both walls provided a greater C-index improvement than assessing CCA-IMT at one wall only [+0.0046 vs. +0.0023 for near (P < 0.001), +0.0037 for far wall (P = 0.006)]. Conclusions: The associations of near and far wall CCA-IMT with incident CVD were positive, approximately linear, and similarly strong. Improvement in risk discrimination was highest when CCA-IMT was measured at both walls.

The structured ambulatory post-stroke care program for outpatient aftercare in patients with ischaemic stroke in Germany (SANO): an open-label, cluster-randomised controlled trial.

BACKGROUND: Patients with ischaemic stroke are at risk of recurrent stroke. In this study, we aimed to compare the effect of a structured ambulatory post-stroke care programme versus usual care on recurrent vascular events and death and control of cardiovascular risk factors. METHODS: We did a prospective, open-label, cluster-randomised controlled trial (SANO) at stroke centres in regions of Germany. A cluster was defined as a region in which acute stroke care is provided by a participating stroke centre. Patients were eligible for participation if they were aged 18 years or older, had no severe disabilities before the index stroke (modified Rankin scale 0-1), had at least one modifiable cardiovascular risk factor, and presented within 14 days of symptom onset of their first ischaemic stroke. The participating regions were randomly assigned (1:1) to the intervention and control group (usual care) by the statistician using block randomisation (block sizes of six), stratified by rural and urban regions. In intervention regions, a cross-sectoral multidisciplinary network was established to provide a 1-year organisational and patient-centred intervention. Due to the type of intervention, masking of participants and study physicians was not possible. Endpoint adjudication was performed by an independent endpoint adjudication committee who were masked to cluster allocation. The primary endpoint was a composite of recurrent stroke, myocardial infarction, and all-cause death within 12 months after baseline assessment, assessed in the modified intention-to-treat (mITT) population, which included all patients who did not withdraw consent and completed the primary endpoint assessment at 12 months. This study was registered with the German Clinical Trials Register, DRKS00015322. FINDINGS: Between Jan 1, 2019 and Dec 22, 2020, 36 clusters were assessed for eligibility, of which 30 were randomly assigned to the intervention group (n=15 clusters) or control group (n=15 clusters). No clusters dropped out of the study. 1203 (86%) of 1396 enrolled patients in the intervention group and 1283 (92%) of 1395 enrolled patients in the control group were included in the mITT population. The primary endpoint was confirmed in 64 (5·3%) of 1203 patients in the intervention group and 80 (6·2%) of 1283 patients in the control group (unadjusted odds ratio [OR] 0·80 [95% CI 0·49-1·30]; adjusted OR [aOR] 0·95 [95% CI 0·54-1·67]). All-cause deaths occurred in 31 (2·4%) of 1203 patients in the intervention group and 12 (1·0%) of 1283 patients in the control group. The incidence of serious adverse events was higher in the intervention group (266 [23·1%] of 1151) than the control group (106 [9·2%] of 1152). Falls (134 [11·4%] of 1203 patients in the intervention group; 39 [3·3%] of 1152 patients in the control group), hypertensive crisis (55 [4·7%]; 34 [2·8%]), and diagnosis of depression (51 [4·3%]; 13 [1·1%]) were the most frequent adverse events in both groups. No differences were identified in the rate of readmission to hospital between groups. INTERPRETATION: No differences were identified between patients with ischaemic stroke in the intervention group and control group with regard to the incidence of vascular events 1 year after baseline assessment, despite positive effects with regard to the control of some cardiovascular risk factors. Longer-term effects and other potentially favourable effects on stroke-related sequelae and quality of life require further evaluation. FUNDING: Innovation Fund of the Federal Joint Committee.

Guideline "Transient Global Amnesia (TGA)" of the German Society of Neurology (Deutsche Gesellschaft für Neurologie): S1-guideline.

INTRODUCTION: In 2022 the DGN (Deutsche Gesellschaft für Neurologie) published an updated Transient Global Amnesia (TGA) guideline. TGA is characterized by a sudden onset of retrograde and anterograde amnesia for a period of one to a maximum of 24 h (with an average of 6 to 8 h). The incidence is estimated between 3 and 8 per 100,000 population/year. TGA is a disorder that occurs predominantly between 50 and 70 years. RECOMMENDATIONS: The diagnosis of TGA should be made clinically. In case of an atypical clinical presentation or suspicion of a possible differential diagnosis, further diagnostics should be performed immediately. The detection of typical unilateral or bilateral punctate DWI/T2 lesions in the hippocampus (especially the CA1 region) in a proportion of patients proves TGA. The sensitivity of MRI is considered higher when performed between 24 and 72 h after onset. If additional DWI changes occur outside the hippocampus, a vascular etiology should be considered, and prompt sonographic and cardiac diagnostics should be performed EEG may help to differentiate TGA from rare amnestic epileptic attacks, especially in recurrent amnestic attacks. TGA in patients < 50 years of age is a rarity, therefore it is mandatory to rapidly search for other causes in particular in younger patients. The cause of TGA is still unknown. Numerous findings in recent years point to a multifactorial genesis. Because the pathomechanism of TGA is not yet clearly known, no evidence-based therapeutic or prophylactic recommendations can be made. CONCLUSIONS: There is no evidence for chronic sequelae of TGA with respect to cerebral ischemia, chronic memory impairment, or the onset of dementia-related syndromes.

[Position paper on stroke aftercare of the German Stroke Society-Part 1: long-term care after stroke: status quo of the reality and deficits of care in Germany]. / Positionspapier Schlaganfallnachsorge der Deutschen Schlaganfall-Gesellschaft ­ Teil 1: Nachsorge nach einem Schlaganfall: Status quo der Versorgungsrealität und Versorgungsdefizite in Deutschland.

The acute treatment of stroke patients in Germany is of a very high standard, guaranteed by its system of stroke units. Stroke as a disease has an acute phase followed by a chronic phase that requires a high level of qualified aftercare given by multidisciplinary and interdisciplinary teams. In 2020, the German Stroke Society (DSG) founded a commission for long-term stroke care. The aim is to evaluate the current situation of long-term aftercare and suggest improvements for its structure. In this paper the status quo of aftercare is presented and possible deficits are identified. Contributions of various stakeholders from the German healthcare system are analyzed and different projects for post-acute care are presented. Germany has no acknowledged structured aftercare concepts for patients after stroke. The general practitioner-based care is currently the focus of patient management but without a greater, more coordinated integration of neurologists, guideline-led and quality-controlled aftercare will be harder to implement in the future. The assignment of duties and the necessary training standards for the specialist groups in order to comply with the guidelines do not exist. Besides medical health, the needs of physical, social and emotional domains are too seldom considered by a multiprofessional care team. Further developments of a regional care management concept are discussed. The results and costs of any aftercare concepts must be evaluated before widespread implementation.

[Position paper on stroke aftercare of the German Stroke Society-Part 2: concept for a comprehensive stroke aftercare]. / Positionspapier Schlaganfallnachsorge der Deutschen Schlaganfall-Gesellschaft ­ Teil 2: Konzept für eine umfassende Schlaganfallnachsorge.

Long-term management after stroke has not been standardized in contrast to acute and rehabilitative stroke care. The fragmented outpatient sector of healthcare allows a high degree of flexibility but also variability in the quality of care provided. The commission on long-term stroke care of the German Stroke Society developed a concept on how to provide standardized multiprofessional long-term stroke care with a focus on patient-centered comprehensive care. We propose a diagnostic work-up in stages, with an initial patient-reported screening, followed by an adapted in-depth assessment of affected domains. This includes internistic domains (management of risk factors) and also genuine neurological domains (spasticity, cognitive deficits etc.) that must be considered. This information is then merged with patient expectations and prioritization to a standardized treatment plan. Special challenges for the implementation of such a comprehensive care system are the intersectoral and intrasectoral communication between healthcare providers, patients and relatives, the need to create a compensation system for providers and the establishment of appropriate quality management services. Digital health applications are helpful tools to provide aspects of diagnostics, treatment and communication in long-term stroke care.

Trial design and pilot phase results of a cluster-randomised intervention trial to improve stroke care after hospital discharge - The structured ambulatory post-stroke care program (SANO).

INTRODUCTION: Previous studies showed insufficient control of cardiovascular risk factors (CVRF) and high stroke recurrence rates among ischemic stroke patients in Germany. Currently, no structured secondary prevention program exists in clinical routine. We present the trial design and pilot phase results of a complex intervention to improve stroke care after hospital discharge in Germany. PATIENTS AND METHODS: SANO is a cluster-randomized trial with 30 participating regions across Germany aiming to enrol 2,790 patients (drks.de, DRKS00015322). Study intervention combines both structural and patient-centred elements. Study development was based on the Medical Research Council framework for complex interventions. In 15 intervention regions, a cross-sectoral multidisciplinary network is established to enhance CVRF control as well as detection and treatment of post-stroke complications. Recommendations on CVRF are based on high-quality secondary prevention guidelines. Study physicians use motivational interviewing and agree with patients on therapeutic targets. While hospitalised, patients also receive dietary counselling and a health-passport to track their progress. During regular visits, CVRF management and potential complications are monitored. The intervention is compared to 15 regions providing usual care. The primary endpoint is the combination of recurrent stroke, myocardial infarction and death assessed 12 months after enrolment and adjudicated in a blinded manner. RESULTS: Eighteen patients were enrolled in a pilot phase that demonstrated feasibility of patient recruitment and study procedures. CONCLUSION: SANO is investigating a program to reduce outcome events after ischemic stroke by implementing a complex intervention. If successful, the program may be implemented in routine care on national level in Germany.

[Asymptomatic carotid stenosis: What is new?] / Die asymptomatische Karotisstenose: Was ist neu?

In industrialized countries, stroke is still the most common disease that leads to permanent disability. Of the 250 000 strokes that occur annually in Germany, in about 80 % are cerebral ischemia. Approximately 15 % of these ischemias are caused by lesions of the extracranial internal carotid artery, so optimal treatment of extracranial carotid stenosis is essential 1. This continues to be the subject of a controversial debate, as optimized drug therapy has led to a significant reduction in risk.In 2020, the multidisciplinary S3 guideline for the management of extracranial carotid stenoses was updated. In the following, current aspects and new recommendations for asymptomatic carotid stenosis are presented and important innovations of the guideline are explained.

Chemsex and Mental Health of Men Who Have Sex With Men in Germany.

Background: Chemsex is defined as using certain substances immediately before or during sexual activities to facilitate, prolong and/or intensify sexual experience, mainly by some communities of men who have sex with men (MSM). Four substances are typically associated with chemsex: methamphetamine, mephedrone, GHB/GBL, and ketamine. While there is a lot of evidence for increased prevalence of HIV, sexually transmitted infections and other sexual health measures among MSM, who engage in chemsex, there has been little research on mental health aspects. This study aims to describe aspects of mental health among a sample of German men who have sex with men (MSM) who engage in chemsex and to describe potentially adverse consequences of chemsex behavior. Method: This paper refers to a subset of participants from the German Chemsex Survey, an MSM-community recruited, self-completed online survey with a self-selected convenience sample. The survey comprised 420 different items considering recreational substance use, substance use in sexual settings, mental health, sexual transmitted infections, adverse consequences of chemsex behavior, and experiences of non-consensual sex acts. A group of participants who used methamphetamine, mephedrone, GHB/GBL, and/or ketamine in a sexual setting in the last 12 months (n = 280, chemsex group) was analyzed regarding symptoms of depression (PHQ-9), general anxiety disorder (GAD-7), somatization (PHQ-15), and PTSD (Primary Care PTSD Screen). Group comparisons were conducted between the chemsex group and men who did not use substances in a sexual context (n = 177, non-chemsex group). Mean scores of mental health measures were compared, as well as scores above a cut-off that indicates clinically relevant symptoms. Logistical regression was utilized to determine whether mental health measures can predict adverse consequences of engagement in chemsex behaviors. Results: A total of 1,583 men started the survey; 1,050 participants provided information on substance use. Twenty-seven percent of participants (n = 280) reported that they used methamphetamine, mephedrone, GHB/GBL and/or ketamine in a sexual setting in the last 12 months. The chemsex group showed significantly higher mean scores for depression, anxiety, and somatization than the non-chemsex group, but effect sizes were low. Even though mean scores were heightened, they were still far below the cut-off for clinically relevant symptoms. The chemsex group reported significantly higher incidences of non-consensual sex acts compared with the non-chemsex group. Some men in the chemsex-group experienced potentially adverse consequences, such as loss of control regarding time and money spent for chemsex activities or amount of substances used at one occasion (49.6%), negative impacts on social functioning (33.6%), psychotic symptoms (13.2%), and physically aggressive behavior toward others (2.9%). Clinically relevant symptoms did not predict a higher likelihood for adverse consequences. Discussion: Mean scores for depression, anxiety, and somatization were significantly higher in the chemsex-group, but effect sizes were low. Both groups reported poorer mental health compared to men in the German general population. Mental health measures did not contribute to predict potentially adverse consequences of chemsex behavior.

[Prevention of stroke and dementia in general practice: evaluation of the project INVADE]. / Prävention von Schlaganfall und Demenz in der Hausarztpraxis: Evaluation des Projektes INVADE.

BACKGROUND: Stroke and dementia have several modifiable risk factors in common. In the primary care prevention project INVADE (INtervention project on VAscular brain diseases and Dementia in the district of Ebersberg), these vascular risk factors were recorded systematically and treated according to evidence-based guidelines. METHODS: All insurants of the AOK Bayern who were ≥ 50 years of age and lived in the Upper Bavarian district of Ebersberg received the offer to participate in INVADE, about one-third enrolled in the program. Examinations by the family doctor, self-reports of the participants, laboratory analyses, and a duplex sonography of the extracranial neck vessels were used to create individual risk profiles, from which the intervention measures were derived. GPs documented the treatment and health status of the participants at quarterly intervals. The entire examination program was repeated every two years. The success of the intervention was determined in comparison with the district of Dachau, where the insurants received the primary care treatment as usual. Administrative data of the health and long-term care fund for the period from 2013 to 2016 were used as clinical endpoints. Primary endpoints included mortality and onset of long-term care, secondary endpoints were inpatient treatments due to cerebrovascular disease. RESULTS: The comparison between the district of Ebersberg (N = 10.663) and the district of Dachau (N = 13.225) was in favor of the prevention program for both the primary clinical endpoints and the combined secondary endpoint. Mortality risk (HR = 0.90; 95 % confidence interval: 0.84-0.97), long-term care risk (HR = 0.88; 0.81-0.96), and the likelihood of inpatient treatment for cerebrovascular disease (OR = 0.87; 0.77-0.97) were significantly reduced. CONCLUSIONS: The results support the assumption that the incidence of cerebrovascular disease and dementia can be reduced by a systematic general-practice based identification and treatment of vascular risk factors and can thus increase life expectancy and disability-free life time.

Diagnosis, Treatment and Follow-up in Extracranial Carotid Stenosis.

BACKGROUND: Around 15% of cerebral ischemias are caused by lesions of the extracranial carotid artery. The goal of this guideline is to provide evidence- and consensus-based recommendations for the management of patients with extracranial carotid stenoses throughout Germany and Austria. METHODS: A systematic literature search (1990-2019) and methodical assessment of existing guidelines and systematic reviews; consensus-based answers to 37 key questions with evidence-based recommendations. RESULTS: The prevalence of extracranial carotid artery stenoses is around 4% overall, higher from the age of 65 years. The most important examination modality is duplex sonography. Randomized trials have shown that carotid endarterectomy (CEA) significantly reduces the 5-year risk of stroke in patients with 60-99 % asymptomatic stenoses (absolute risk reduction [ARR] 4.1% over 5 years, number needed to treat [NNT] 24) or 50-99% symptomatic stenoses (50-69%: ARR 4.6 % over 5 years, NNT 22; 70-99%: 15.9 % over 5 years, NNT 6). With the aid of intensive conservative treatment, the carotid artery-associated risk of stroke can be reduced to as little as 1% per year. Critical determination of indications and strict quality criteria are therefore necessary for CEA and carotid artery stenting (CAS). Systematic reviews of controlled trials comparing CEA and CAS show that the procedural risk of stroke is higher for CAS (asymptomatic: 2.6% versus 1.3%; symptomatic: 6.2% versus 3.8%). There are no differences in the long term. CEA is recommended as standard procedure for high-grade asymptomatic and moderate to high-grade symptomatic carotid artery stenoses; CAS may be considered as an alternative. For both procedures, the periprocedural combined rate of stroke or death should not exceed 2% for asymptomatic stenoses or 4% for symptomatic stenoses. CONCLUSION: Future studies should evaluate even better selection criteria for optimal individualized treatment, whether conservative, surgical, or endovascular.

Progression of conventional cardiovascular risk factors and vascular disease risk in individuals: insights from the PROG-IMT consortium.

AIMS: Averaged measurements, but not the progression based on multiple assessments of carotid intima-media thickness, (cIMT) are predictive of cardiovascular disease (CVD) events in individuals. Whether this is true for conventional risk factors is unclear. METHODS AND RESULTS: An individual participant meta-analysis was used to associate the annualised progression of systolic blood pressure, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol with future cardiovascular disease risk in 13 prospective cohort studies of the PROG-IMT collaboration (n = 34,072). Follow-up data included information on a combined cardiovascular disease endpoint of myocardial infarction, stroke, or vascular death. In secondary analyses, annualised progression was replaced with average. Log hazard ratios per standard deviation difference were pooled across studies by a random effects meta-analysis. In primary analysis, the annualised progression of total cholesterol was marginally related to a higher cardiovascular disease risk (hazard ratio (HR) 1.04, 95% confidence interval (CI) 1.00 to 1.07). The annualised progression of systolic blood pressure, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol was not associated with future cardiovascular disease risk. In secondary analysis, average systolic blood pressure (HR 1.20 95% CI 1.11 to 1.29) and low-density lipoprotein cholesterol (HR 1.09, 95% CI 1.02 to 1.16) were related to a greater, while high-density lipoprotein cholesterol (HR 0.92, 95% CI 0.88 to 0.97) was related to a lower risk of future cardiovascular disease events. CONCLUSION: Averaged measurements of systolic blood pressure, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol displayed significant linear relationships with the risk of future cardiovascular disease events. However, there was no clear association between the annualised progression of these conventional risk factors in individuals with the risk of future clinical endpoints.

Crystal Methamphetamine Use in Sexual Settings Among German Men Who Have Sex With Men.

Introduction: Men who have sex with men (MSM) are a vulnerable subgroup for problems with substance use, including crystal methamphetamine. Drug use in sexual settings, commonly referred to as "chemsex," has been an issue of growing concern in MSM communities. Recreational drugs commonly associated with chemsex include crystal methamphetamine, gamma-hydroxybutyrate/gamma-butyrolactone (GHB/GBL), mephedrone, and ketamine. Drug use in sexual settings is correlated with sexual practices associated with the acquisition and transmission of sexually transmitted infections, including HIV and hepatitis C. Adverse mental health outcomes are often reported at higher rates among MSM who use methamphetamine. Methods: This paper refers to a subset of participants from the German Chemsex Survey, an MSM-community recruited, self-completed online survey with a self-selected convenience sample. Participants who used crystal methamphetamine for sex (n = 130) were compared to participants who did not use drugs for sex (n = 177). The survey comprised 420 different items considering recreational substance use, substance use in sexual settings, harm reduction strategies, mental health, sexual transmitted infections, and mental health care service utilization. Results: A total of 1,583 men started the survey; 1,050 participants provided information on substance use. Twenty-seven percent of participants used crystal methamphetamine in the last 12 months, and of those, 89% used methamphetamine in a sexual setting and 50% reported injecting methamphetamine. Regarding mental health, participants who reported methamphetamine use in sexual settings were more likely to report symptoms of depression, somatization, anxiety, and posttraumatic stress disorder (PTSD) than the German male general population. Participants who reported methamphetamine use for sex were more likely to report symptoms of major depression, being HIV positive, and taking HIV pre-exposure prophylaxis (PrEP) than participants who did not report methamphetamine use. Most participants used harm reduction practices to reduce the risks associated with using methamphetamine in sexual settings. Conclusion: Crystal methamphetamine is used in the context of sexual activities by German MSM. Poorer mental health status than in the male general population was observed. MSM who used methamphetamine in this study seemed to be aware of potential health risks associated with their substance use and utilized harm reduction strategies and biomedical HIV prevention strategies like PrEP.

Knowledge and use of HIV pre-exposure prophylaxis among men who have sex with men in Berlin - A multicentre, cross-sectional survey.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) has likely contributed to large decreases in HIV incidence among men who have sex with men (MSM) in several major cities. Berlin has seen a smaller decline, and affordable PrEP has been accessible through formal channels in Germany only since autumn 2017. We aimed to investigate knowledge and use of PrEP among MSM in Berlin, and factors predictive of a desire to use PrEP and history of PrEP use. METHODS: Multicentre, paper-based, self-administered survey of adult MSM whose HIV status was negative or unknown at time of participation. Data were collected from 1 October 2017 to 2 April 2018. RESULTS: 473 of 875 questionnaires were returned (response rate 54.1%; mean age 37.4 years, range 18-79). 90.0% of participants were aware of PrEP and, of these, 48.2% felt well informed about it. Among the 17.2% of participants reporting PrEP use, 59.3% indicated obtaining some or all of it from informal sources. 23.7% of those with no history of PrEP use reported having condomless anal intercourse (CAI) with two or more partners over the past six months. Worries about side effects, cost, not having a doctor who prescribes it, and a lack of information were the most frequently reported barriers to PrEP use. A desire to use PrEP and history of PrEP use were associated in our multivariable model with having multiple CAI partners. A history of PrEP use was associated with having a university degree, one or two parents born outside Germany, or friends living with HIV. CONCLUSIONS: We found high awareness of PrEP among MSM in Berlin, but also a strong need for more education on its pros, cons and proper use. The frequency of informal PrEP use was also high, raising urgent individual and public health concerns. Policy makers need to consider recent calls to improve access to PrEP and PrEP education through regular health services.

Apathy and depressive symptoms in older people and incident myocardial infarction, stroke, and mortality: a systematic review and meta-analysis of individual participant data.

Background: Previous findings suggest that apathy symptoms independently of depressive symptoms measured using the Geriatric Depression Scale (GDS) are associated with cardiovascular disease (CVD) in older individuals. Aims: To study whether apathy and depressive symptoms in older people are associated with future CVD, stroke, and mortality using individual patient-data meta-analysis. Methods: Medline, Embase, and PsycInfo databases up to September 3, 2013, were systematically searched without language restrictions. We sought prospective studies with older (mean age ≥65 years) community-dwelling populations in which the GDS was employed and subsequent stroke and/or CVD were recorded to provide individual participant data. Apathy symptoms were defined as the three apathy-related subitems of the GDS, with depressive symptoms the remaining items. We used myocardial infarction (MI), stroke, and all-cause mortality as main outcomes. Analyses were adjusted for age, sex, and MI/stroke history. An adaptation of the Newcastle-Ottawa scale was used to evaluate bias. Hazard ratios were calculated using one-stage random-effect Cox regression models. Results: Of the 52 eligible studies, 21 (40.4%) were included, comprising 47,625 older people (mean age [standard deviation] 74 [7.4] years), over a median follow-up of 8.8 years. Participants with apathy symptoms had a 21% higher risk of MI (95% confidence interval [CI] 1.08-1.36), a 37% higher risk of stroke (95% CI 1.18-1.59), and a 47% higher risk of all-cause mortality (95% CI 1.38-1.56). Participants with depressive symptoms had a comparably higher risk of stroke (HR 1.36, 95% CI 1.18-1.56) and all-cause mortality (HR 1.44, 95% CI 1.35-1.53), but not of MI (HR 1.08, 95% CI 0.91-1.29). Associations for isolated apathy and isolated depressive symptoms were comparable. Sensitivity analyses according to risk of bias yielded similar results. Conclusion: Our findings stress the clinical importance of recognizing apathy independently of depressive symptoms, and could help physicians identify persons at increased risk of vascular disease.

Predictive value for cardiovascular events of common carotid intima media thickness and its rate of change in individuals at high cardiovascular risk - Results from the PROG-IMT collaboration.

AIMS: Carotid intima media thickness (CIMT) predicts cardiovascular (CVD) events, but the predictive value of CIMT change is debated. We assessed the relation between CIMT change and events in individuals at high cardiovascular risk. METHODS AND RESULTS: From 31 cohorts with two CIMT scans (total n = 89070) on average 3.6 years apart and clinical follow-up, subcohorts were drawn: (A) individuals with at least 3 cardiovascular risk factors without previous CVD events, (B) individuals with carotid plaques without previous CVD events, and (C) individuals with previous CVD events. Cox regression models were fit to estimate the hazard ratio (HR) of the combined endpoint (myocardial infarction, stroke or vascular death) per standard deviation (SD) of CIMT change, adjusted for CVD risk factors. These HRs were pooled across studies. In groups A, B and C we observed 3483, 2845 and 1165 endpoint events, respectively. Average common CIMT was 0.79mm (SD 0.16mm), and annual common CIMT change was 0.01mm (SD 0.07mm), both in group A. The pooled HR per SD of annual common CIMT change (0.02 to 0.43mm) was 0.99 (95% confidence interval: 0.95-1.02) in group A, 0.98 (0.93-1.04) in group B, and 0.95 (0.89-1.04) in group C. The HR per SD of common CIMT (average of the first and the second CIMT scan, 0.09 to 0.75mm) was 1.15 (1.07-1.23) in group A, 1.13 (1.05-1.22) in group B, and 1.12 (1.05-1.20) in group C. CONCLUSIONS: We confirm that common CIMT is associated with future CVD events in individuals at high risk. CIMT change does not relate to future event risk in high-risk individuals.

Chemsex among men who have sex with men in Germany: motives, consequences and the response of the support system.

Background In Germany, drug use in sexual settings (i.e. chemsex) among men who have sex with men (MSM) has increasingly been the subject of discussion for considerable time. At the same time, however, little is known about this practice. It is against this background that what is currently known about chemsex among MSM in Germany is discussed. METHODS: The present study observations are essentially based on the results of two research projects of a qualitative-explorative nature. In-depth interviews with drug-using MSM (n=14), as well as qualitative, problem-centred interviews with drug-using MSM (n=75) and expert interviews (n=27) were conducted within these research projects. RESULTS: Chemsex is a minority behaviour among MSM in Germany. The reasons for using drugs in sexual settings are manifold. For the most part, the effects of the drugs are used to intensify sexual feelings and to achieve greater intimacy. Men who consider their consumption to be problematic, in particular, report a range of negative consequences, such as sexually transmissible infections. Even though chemsex is a minority behaviour, suitable offers of support are, hence, necessary, especially for these men. However, such offers are not yet available in most German cities. CONCLUSIONS: In order to close this gap in provision of support services, tangible practical steps, such as further training of people who work at drug and gay advisory services, are necessary, along with further research into the backgrounds and contexts of chemsex.
