Evidence for changes in population-level subjective well-being during the COVID-19 pandemic from 30 waves of representative panel data collected in Austria between March 2020 and March 2022.

OBJECTIVES: This study was conducted to describe how population-level subjective well-being (SWB) evolved throughout the pandemic. STUDY DESIGN: Thirty waves of panel data representative of the Austrian population aged ≥14 years were collected between March 2020 and March 2022. Participants were quota sampled from a pre-existing online panel based on key demographics closely mirroring the Austrian resident population. METHODS: We present wave-specific means of SWB throughout 2 years of the COVID-19 pandemic next to the evolution of the pandemic (cases and deaths) and stringency of lockdown measures in Austria as well as estimate their bivariate correlations. RESULTS: The analysed sample consisted of 3,293 participants contributing to a total of 46,168 observations. All components of SWB - negative affect, positive affect and life satisfaction - showed population-level fluctuation between March 2020 and March 2022. The magnitude of these changes was small. Population-level SWB correlated with the incidence rate of COVID-19 deaths (negative affect: r = 0.69, positive affect: r = -0.70, life satisfaction: r = -0.47), the Stringency Index (negative affect = 0.50, positive affect = -0.47, life satisfaction = -0.47) and less so with the incidence of COVID-19 cases (negative affect = 0.43, positive affect = -0.31, life satisfaction = -0.38). CONCLUSIONS: Population-level SWB fluctuated in accordance with rises and falls in COVID-19 cases and deaths as well as with the stringency of lockdown measures. This connection suggests that incidence of COVID-19 cases and deaths, as well as public health measures to contain the pandemic affect population-level SWB and could thereby impact population health and productivity.

Trajectories of loneliness, depressive symptoms, and anxiety symptoms during the COVID-19 pandemic in Austria.

OBJECTIVE: There is considerable heterogeneity within populations regarding the effects of the COVID-19 pandemic on mental health. This study aimed at identifying latent groups of individuals within the older Austrian population that differ in their mental health trajectories across three phases of the pandemic. STUDY DESIGN: Data were gathered from a longitudinal survey study among a sample of older adults in Austria. The survey was carried out in May 2020 (N1 = 556), March 2021 (N2 = 462), and December 2021 (N3 = 370) via either computer-assisted web or telephone interviewing. METHODS: Latent class growth analysis was conducted to explore different homogenous groups in terms of non-linear trajectories of loneliness, depressive symptoms, and anxiety symptoms as well as potential correlates thereof. RESULTS: We identified four latent classes. The vast majority of individuals belong to two classes that are either resilient (71%) or that have recovered relatively quickly from an initial COVID-19 shock (10.2%). Deterioration in mental health after the first phase of the pandemic (13.4%) or a generally high mental health burden (5.4%) characterizes the other two classes. CONCLUSIONS: About 19% of individuals showed increasing or elevated levels in loneliness, depressive symptoms, and anxiety symptoms across the COVID-19 pandemic. The feeling of being socially supported and in control over one's own life emerged as potentially protective factors.

Longitudinal effects of COVID-19-related loneliness on symptoms of mental distress among older adults in Austria.

OBJECTIVE: COVID-19-related social restrictions resulted in more loneliness, but whether this had further effects on mental health remains unclear. This study aimed at examining the longitudinal effects of COVID-19-related loneliness on mental health among older adults (aged ≥60 years) in Austria. STUDY DESIGN: Survey data were gathered from a longitudinal observational study among a random sample of older Austrian adults. The first survey wave was conducted in May 2020 (N1 = 557), and the second wave was conducted in March 2021 (N2 = 463). METHODS: Data collection was based on either computer-assisted web or telephone interviewing. For statistical analysis, we used a cross-lagged panel analysis. RESULTS: The results showed the perceived COVID-19-related social restrictions to predict loneliness, which in turn predicted depressive and anxiety symptoms 10 months later. CONCLUSIONS: COVID-19-related loneliness emerged as a risk factor for subsequent mental distress among older adults in Austria.

[Attitudes Towards End-of-Life Decisions and Long-Term Care Dependency: Results of a Representative Survey of Austrians Aged 50]. / Einstellungen zu Entscheidungen am Lebensende und Pflegebedürftigkeit: Ergebnisse einer repräsentativen Befragung der österreichischen Bevölkerung (50+).

AIM OF THE STUDY: Existing research on attitudes in the general population regarding end-of-life decisions has included neither old age long-term care dependency nor worries regarding age(ing). The aim of this study is to present first results from a recent survey on this topic. METHODS: A nationally representative cross-sectional survey of the population aged 50+was conducted in Austria (n=968) in 2015. RESULTS: 29.0% of the respondents indicated not wanting to live on as a severely care-dependent older person. In the case of an older care-dependent person, 48.5% approved of forgoing life-sustaining treatment, 41.7% of assisted suicide and 34.1% of euthanasia if requested. Worries about old age and ageing were widespread (53.7-83.0%) and highly worried respondents were more inclined to support assisted suicide and euthanasia compared to those less worried. CONCLUSIONS: Worries and negative stereotypes regarding age(ing) and long-term care dependency should be addressed by information campaigns.

Systemic thrombolysis for cerebral venous and dural sinus thrombosis: a systematic review.

BACKGROUND: The use of thrombolytics is frequently considered in patients with cerebral venous and dural sinus thrombosis (CVT) who deteriorate despite anticoagulant therapy. PURPOSE: To collect all the published information about the use of systemic thrombolysis in CVT in order to assess its efficacy and safety. METHODS: We performed a PubMed search, checked all reference lists of studies found and used data from the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT). Outcome was classified at the last available follow-up by the modified Rankin Scale (mRS). The cases were stratified according to variables that might influence outcome. RESULTS: A total of 16 reports (26 patients, 2 from the ISCVT and 24 from the systematic review of the literature) were included. No randomized clinical trial was found. Seven patients presented with isolated intracranial hypertension syndrome (26.9%), 17 with encephalopathy (65.4%) and 2 were comatose (7.7%). The superior sagittal sinus was the one most often affected (n = 21; 80.8%), and there was thrombosis of the deep cerebral venous system in 5 patients (19.2%). Urokinase was the thrombolytic agent most frequently administered (n = 19; 73.1%), whereas streptokinase and recombinant tissue plasminogen activator were used in 2 cases each (7.7%). Intracranial hemorrhages occurred in 3 cases (11.5%). Extracranial hemorrhages occurred in 5 cases (19.2%), and overall there were 3 cases of serious bleeding (11.5%), including 2 deaths (7.7%). Partial or complete recanalization was verified in most patients (n = 16; 61.5%). The survival rate was 92.3% (24/26 patients). At the last available follow-up, 22/25 patients regained independency (mRS scores 0-2; 88%), 2/25 died (mRS score 6; 8%) and 1/25 was severely dependent (mRS scores 3-5; 4%). CONCLUSIONS: In all, 88% of the CVT patients treated with systemic thrombolysis regained their independency, but 2 deaths associated with intracranial hemorrhage occurred. The mortality rate and disability at the last available follow-up were similar to those found in 2 previous systematic reviews concerning the use of thrombolytics in CVT. Due to the small sample size and lack of controls, the efficacy of systemic thrombolysis in acute CVT cannot be assessed from the published information. Concerning safety, a nonnegligible proportion of bleedings was reported.

Observational case-control study of the prevalence of chronic cerebrospinal venous insufficiency in multiple sclerosis: results from the CoSMo study.

BACKGROUND: Chronic cerebrospinal venous insufficiency (CCSVI) has been proposed as a possible cause of multiple sclerosis (MS). OBJECTIVES: The CoSMo study evaluated the association between CCSVI and MS. METHODS: The primary end-point of this multicentric, case-control study was to compare the prevalence of CCSVI between patients with MS, patients with other neurodegenerative diseases (ONDs) and healthy controls (HCs). Color-coded duplex sonography was performed by a sonologist and the images were sent to one of three central sonologists for a second reading. Agreement between local and central sonologists or, in case of disagreement, the predominant judgment among the three central readers, was required for a diagnosis of CCSVI. All readings, data collection and analysis were blinded. RESULTS: The study involved 35 MS centers across Italy and included 1874 subjects aged 18-55. 1767 (94%) were evaluable: 1165 MS patients, 226 patients with ONDs and 376 HCs. CCSVI prevalence was 3.26%, 3.10% and 2.13% for the MS, OND and HC groups, respectively. No significant difference in CCSVI prevalence was found amongst the three cohorts (MS versus HC, OR = 1.55, 95%CI = 0.72-3.36, p = 0.30; OND versus HC, OR = 1.47, 95%CI = 0.53-4.11, p = 0.46; MS versus OND, OR = 1.05, 95%CI = 0.47-2.39, p = 0.99). High negative and low positive agreement was found between the local and centralized readers. CONCLUSIONS: CCSVI is not associated with MS.

Lack of increase of cerebrovascular events during German World Cup soccer games in 2006.

An association of passively watching a soccer game with an incidence of cardiovascular events was previously reported. With access to the stroke database of the Federal State of Hesse, Germany, we examined whether the incidence of cerebrovascular events was elevated during the Federation Internationale de Football Association (FIFA) World Cup in Germany from 9 June to 9 July 2006 on days of matches involving the German team and whether particular characteristics were noted in stroke patients on these days. We analyzed a prospective stroke registry and calculated incidence ratios for the 7 days of matches played by the German team as compared with the control period ranging from May 2006 to July 2006 using a Poisson regression with a log link to model the number of cerebrovascular events per day for all patients and for subgroups of patients, grouped according to sex, severity of stroke, type of stroke and risk factors. About 2,918 patients with ischemic stroke or intracerebral hemorrhage were included. The regression model did not disclose a higher incidence of cerebrovascular events on days of matches played by the German team. Onset admission time on these days was significantly reduced. In contrast to recent observations regarding cardiac events, we found no effect of passively watching soccer games on incidence of stroke or intracerebral hemorrhage, probably because of the different underlying pathophysiologies of stroke and cardiac events. Onset admission time was slightly reduced on days when a German match was played, probably since more strokes occurred under observation of potential support persons, reflecting the tendency of German people to gather to watch matches played by the national team.

Paraneoplastic neurological syndromes in patients with carcinoid.

BACKGROUND: Paraneoplastic neurological syndromes (PNS) are mainly associated with small-cell lung cancer, gynaecological tumours and lymphomas. Few studies report the association of neurological syndromes with a carcinoid, the majority being a serotonin-related myopathy. We report four patients with a PNS associated with carcinoid. PATIENTS AND RESULTS: The clinical syndromes were sensory neuropathy, limbic encephalitis, myelopathy and brain stem encephalitis. Two patients had antineuronal autoantibodies (one anti-Hu, one anti-Yo), one patient had antinuclear antibodies, and one patient had no autoantibodies. For two of the carcinoids, expression of HuD in the tumour could be demonstrated. CONCLUSION: This study demonstrates that carcinoids can also be associated with classical antineuronal antibody-associated PNS.

Increased prevalence of autoimmune disorders and autoantibodies in parents of children with opsoclonus-myoclonus syndrome (OMS).

Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disease in childhood which can be associated with neuroblastoma. Since autoantibodies have been detected in some patients with OMS, an autoimmune etiology is suspected. We compared the prevalence of autoimmune disorders and autoantibodies in parents of children with OMS and in a group of controls of same age and sex. Autoimmune diseases were found in 15.8% of the parents of OMS children, but only in 2.0% of the controls (p<0.001) There was also an increased prevalence of autoantibodies in the OMS parents (42.8% vs. 8.0%, p<0.001). Thyroid diseases were the most frequent autoimmune diseases found, followed by inflammatory rheumatic diseases. Interestingly, the OMS parents also had significantly more autoantibodies against CNS structures than the controls (p<0.01). These findings support the autoimmune hypothesis of childhood OMS and may also hint to a genetic susceptibility for OMS.

Time course of VCAM-1 and ICAM-1 in CSF in patients with basal ganglia haemorrhage.

OBJECTIVES: In a pilot study we found a correlation of the clinical outcome with adhesion molecule (AM) concentrations in ventricular cerebrospinal fluid (CSF) but not in serum in patients with intracerebral haemorrhage. We now determined the time course of AM concentration in CSF and serum after basal ganglia haemorrhage (BGH) in order to further uncover pathogenetic mechanisms. MATERIALS AND METHODS: We included 11 patients with acute BGH and ventricular tamponade in which an extraventricular drainage had been applied to treat ventricular ballonade. Paired CSF and serum samples were obtained within 8 h after onset of BGH, as well as on the consecutive days 2, 4, 6, and 8, respectively. The concentrations of soluble ICAM-1 (sICAM-1) and VCAM-1 (sVCAM-1) in CSF and serum were measured by enzyme-linked immunosorbent assay. Moreover, we determined blood volume and perifocal oedema by a semi-automated planimetry technique from initial cranial computed tomography scans. RESULTS: sICAM-1 and sVCAM-1 levels in CSF were highest within the first hours after onset of BGH, then decreased significantly (P < 0.005 and <0.05, respectively) on day 2 and slightly increased thereafter. Furthermore, BGH volume was significantly correlated with the concentrations of sICAM-1 (r = 0.63, P < 0.05) and sVCAM-1 (r = 0.66, P < 0.05) in ventricular CSF but not in serum. CONCLUSIONS: Our results might indicate that the local inflammatory reaction is pronounced early after onset of BGH and appears to be restricted to the central nervous system. Moreover, AM concentrations measured early after BGH onset correlated stronger with radiological and clinical data than follow-up measurements.

Recanalization after intravenous thrombolysis: does a recanalization time window exist?

BACKGROUND: To evaluate the time course of major vessel recanalization under IV thrombolysis in relation to functional outcome in acute ischemic stroke. METHODS: A total of 99 patients with an acute anterior circulation vessel occlusion who underwent IV thrombolysis were included. All patients had a standardized admission and follow-up procedure. Color-coded duplex sonography was performed on admission, 30 minutes after thrombolysis, and at 6 and 24 hours after onset of symptoms. Recanalization was classified as complete, partial, and absent. Functional outcome was rated with the modified Rankin Scale on day 30. RESULTS: Complete recanalization occurred significantly more frequently in patients with multiple branch occlusions compared to those with mainstem occlusion (OR 5.33; 95% CI, 2.18 to 13.05; p < 0.0001) and was associated with lower NIH Stroke Scale (NIHSS) scores (p < 0.001). Not the specific time point of recanalization at 6 or 24 hours after stroke onset, but recanalization per se within 24 hours (OR 7.8; 95% CI 2.2 to 28.2; p = 0.002) was significantly associated with a favorable outcome. Multivariate analysis revealed recanalization at any time within 24 hours and NIHSS scores on days 1 and 7 together explaining 75% of the functional outcome variance 30 days after stroke. CONCLUSIONS: Complete recanalization up to 24 hours after stroke onset is significantly associated with the short-term clinical course and functional outcome 30 days after acute stroke.

Circulating microemboli in patients with myeloproliferative disorders.

Myeloproliferative disorders (MPD) are associated with an increased risk for thrombembolic events. In this study, we examined the prognostic value of transcranial Doppler (TCD) microemboli detection regarding clinical events and correlated TCD findings with results of blood cell counts and platelet flow cytometry to gain insight into the composition of circulating microemboli in these patients. In a cohort of 42 patients with MPD TCD microemboli detection was performed on a single occasion and correlated with thrombembolic events during a prospective follow up of 29.7 +/- 7.3 month. In all patients, a complete blood count and in 17 patients platelet flow cytometry were performed on the day of the TCD examination. Microembolic signals (MES) were recorded in 15 (35.7%) patients, however, without any correlation with the type of MPD, blood cell counts, or thrombembolic events [9 (21.4%)]. MES positive and negative patients did not differ regarding the levels of activated platelets, platelet microaggregates, or microparticles. We found a strong trend for higher rates of platelet-neutrophil conjugates in MES positive patients (P = 0.09). Detection of MES by TCD on a single occasion in MPD patients has only limited prognostic value. MES do not correlate with the type of MPD, nor blood cell counts. Flow cytometry suggests that MES in MPD may consist of platelet-neutrophil aggregates.

Failed visualization of clot signal in cerebral venous thrombosis on initial MR imaging.

Currently, the combination of T1- and T2-weighted spin echo magnetic resonance imaging (MRI) sequences with MR venography is considered the best diagnostic tool for diagnosing cerebral venous thrombosis (CVT), because they allow positive identification of the thrombotic clot along with the disturbed venous flow signal. We report two patients in whom initial MRI with the mentioned techniques did not show a clot signal. In both patients anticoagulation was started despit lacking proof of CVT by imaging and both patients improved. Only on repeated MRI sinus clot signal could be confirmed.

Pulmonary perfusion in acute pulmonary embolism: agreement of MRI and SPECT for lobar, segmental and subsegmental perfusion defects.

PURPOSE: To assess prospectively the agreement of magnetic resonance (MR) pulmonary perfusion with single-photon emission computed tomography (SPECT) perfusion for perfusion defects down to the subsegmental level in patients with suspected pulmonary embolism (PE). MATERIAL AND METHODS: In 41 patients with suspected PE, contrast-enhanced MR pulmonary perfusion (3D-FLASH, TR/TE 1.6/0.6 ms) was compared to SPECT perfusion on a per-examination basis as well as at the lobar, segmental, and subsegmental level. RESULTS: The MRI protocol was completed in all patients, and mean examination time was 3 min 56 s. MR perfusion showed a very high agreement with SPECT (kappa value per examination 0.98, and 0.98, 0.83, and 0.69 for lobar, segmental, and subsegmental perfusion defects, respectively). Of 15 patients with PE, MR perfusion detected 14 cases. CONCLUSION: The very high agreement of MR perfusion with SPECT perfusion enables the detection of subtle findings in suspected PE.

Experimental stroke: ischaemic lesion volume and oedema formation differ among rat strains (a comparison between Wistar and Sprague-Dawley rats using MRI).

Investigating focal cerebral ischaemia requires animal models that are relevant to human stroke. This study was designed to evaluate the influence of early reperfusion and choice of rat strains on infarct volume and oedema formation. Thirty-six Wistar and Sprague-Dawley rats were subjected to temporary middle cerebral artery occlusion (MCAO) for 90 min (groups I and II) or to permanent MCAO (groups III and IV) using the suture technique. Ischaemic lesion volume and oedema formation were quantified 24 h after MCAO using 7T-magnetic resonance imaging (MRI). Impact of rat strains: Reperfusion led to significant larger ischaemic lesion volumes in Wistar rats as compared to Sprague-Dawley rats (P<0.0005). Oedema formation was similar in both rat strains. Permanent MCAO led to significantly larger ischaemic lesion volumes in Sprague-Dawley rats (P<0.05). Oedema formation, however, was significantly more accentuated in Wistar rats (P<0.005). Impact of reperfusion: Reperfusion did not cause any changes in ischaemic lesion volume in Wistar rats. Oedema formation, however, was significantly reduced (P<0.0005). In Sprague-Dawley rats, reperfusion caused a significant reduction of ischaemic lesion volume (P<0.00005), but did not modify oedema formation. These findings emphasize the critical importance of rat strain differences in experimental stroke research.

Contribution of diffusion-weighted imaging in determination of stroke etiology.

INTRODUCTION: Diffusion-weighted (DW) MR imaging enables early identification of ischemic lesions in stroke. Stroke subtype may be related to different lesion patterns. The aim of this study was to analyze the subtype of ischemic lesions as determined by the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria by using DW MR imaging. METHODS AND RESULTS: In this study, 510 consecutive patients with ischemic stroke (95%) and transient ischemic attack (5%) aged 65 +/- 12 years were investigated by use of DW MR imaging within 48 hours of the clinical onset of symptoms. Lesions on DW imaging were classified as single, scattered, or multiple lesions in one vascular territory and multiple in more than one vascular territory. We found a significant overall association of DW imaging lesion patterns and classification with stroke subtype by using the TOAST criteria (P < .001). Single corticosubcortical lesions (P < .01) and multiple bilateral lesions in the anterior (AC) and posterior circulation (P < .001) on DW imaging were significantly associated with a cardiac embolic source. Multiple unilateral lesions in the AC were significantly associated with large-artery arteriosclerosis. Because of the 15-mm criterion for small-artery occlusion, cryptogenic stroke was significantly associated with subcortical lesions >/=15 mm. CONCLUSION: We found a strong relationship between stroke subtype and DW imaging lesion pattern. The finding of multiple bilateral lesions was significantly associated with a cardiac embolic source, which may be caused by a specific thrombus texture with a tendency for embolus dissemination.

Antinuclear antibodies define a subgroup of paraneoplastic neuropathies: clinical and immunological data.

OBJECTIVE: Paraneoplastic neuropathy is a clinical and immunological heterogeneous disorder and attempts have been made to classify subgroups of this disease. Only 30-50% of the clinical defined cases have antineuronal antibodies. METHODS: The clinical and immunological features of 36 patients with paraneoplastic neuropathy from the authors' database were analysed including the type and course of the neuropathy, associated tumours, and the presence of antineuronal and other autoantibodies. RESULTS: Antineuronal antibodies were detected in 17/36 patients (47%) and anti-Hu was the most frequent antineuronal antibody. Nine patients had high titre antinuclear antibodies (ANA, median titre 1/1000) without antineuronal antibodies. ANA reactivities were different in most patients. Comparison of the ANA positive and ANA negative patients revealed that ANA positive paraneoplastic neuropathy is more frequently associated with breast cancer but is not associated with lung cancer (p<0.05). The main clinical type in these patients was sensorimotor neuropathy. No ANA positive patient had central nervous system involvement. Although the Rankin score at the time of diagnosis was not different, the functional outcome in ANA positive patients was better than in ANA negative patients (p<0.05). CONCLUSIONS: Paraneoplastic neuropathy is a heterogeneous disorder. ANA may define a subgroup of paraneoplastic neuropathy with different clinical and immunological features and may be related to better prognosis of the neuropathic symptoms.
