In the last years, cognitive impairment was emphasized to be a prominent long‐term sequelae of sepsis. The level of cognitive impairment is comparable with that in mild cognitive impairment (MCI) ...patients. Whether sepsis survivors also show a comparable brain atrophy is still unclear. For the analysis of brain atrophy, a novel method named brain age gap estimation (BrainAGE) was used. In this analysis approach, an algorithm identifies age‐specific atrophy across the whole brain and calculates a BrainAGE score in years. In case of accelerated brain atrophy, the BrainAGE score is increased in comparison to the healthy age reference group, indicating a difference in estimated chronological age. 20 survivors of severe sepsis (longer than 2 years post sepsis) with persistent cognitive deficits were investigated with a battery of neuropsychological tests. Their MRI images were compared to an age‐ and sex‐matched control group. Sepsis survivors showed a significant higher BrainAGE score of 4.5 years compared to healthy controls. We also found a close relationship between the BrainAGE score and severity of cognitive impairment (a higher BrainAGE score was associated with more severe cognitive impairment). Consequently, sepsis survivors with persistent cognitive impairment showed an accelerated brain ageing, which was closely associated with the severity of cognitive impairment (similar to MCI patients).

Physiotherapy is mentioned as an adjunctive treatment to improve the symptoms of cervical dystonia in terms of pain, function and quality of life. However, botulinum neurotoxin injection remains the ...treatment of choice. This systematic review emphasizes physical therapy and evaluates it by including six studies. The methodology is based on a previous systematic review on this topic to provide better comparability and actuality. For this purpose, two databases were searched using the previously published keywords. This time, only randomised controlled trials were evaluated to increase the power. In conclusion, additional physical therapy and active home exercise programs appear to be useful. Further research should focus on the dose-response principle to emphasize physical therapy treatment modalities.
Background Intracranial hemorrhage (ICH) is one of the main causes for lack of surgery in patients with infective endocarditis (IE), despite the presence of surgical indications. We aimed to evaluate ...the impact of early surgery in patients with IE and with ICH on postoperative neurological deterioration and all-cause mortality and to elucidate the risk of 30-day mortality in patients who were denied surgery. Methods and Results Three libraries (MEDLINE, EMBASE, and Cochrane Library) were assessed. The primary outcome was all-cause mortality, and the secondary outcome was neurological deterioration. Inverse variance method and random model were performed. We identified 16 studies including 355 patients. Nine studies examined the impact of surgical timing (early versus late) and were included in the meta-analysis. Only one study examined the fate of patients with IE and with ICH who were treated conservatively despite having an indication for cardiac surgery, showing higher mortality rates than those who underwent surgery (11.8% versus 2.5%). We found no significant association between early surgery, regardless of its definition, and a higher mortality (odds ratio OR, 1.69; 95% CI, 0.95-3.02). Early surgery was associated with higher risk for neurological deterioration (OR, 2.00; 95% CI, 1.10-3.65). Conclusions Cardiac surgery for IE within 30 days of ICH was not associated with higher mortality, but with an increased rate of neurological deterioration. The 30-day mortality in patients with IE and with ICH who were denied surgery has not yet been sufficiently investigated. This patient group should be analyzed in future studies in more detail.
The Harlequin syndrome may occur in patients treated with venoarterial extracorporal membrane oxygenation (VA-ECMO), in whom blood from the left ventricle and the ECMO system supply different parts ...of the body with different paCO2-levels. The purpose of this study was to compare two variants of paCO2-analysis to account for the Harlequin syndrome during apnea testing (AT) in brain death (BD) determination.
Twenty-seven patients (median age 48 years, 26–76 years; male n = 19) with VA-ECMO treatment were included who underwent BD determination. In variant 1, simultaneous arterial blood gas (ABG) samples were drawn from the right and the left radial artery. In variant 2, simultaneous ABG samples were drawn from the right radial artery and the postoxygenator ECMO circuit. Differences in paCO2-levels were analysed for both variants.
At the start of AT, median paCO2-difference between right and left radial artery (variant 1) was 0.90 mmHg (95%-confidence intervall CI: 0.7–1.3 mmHg). Median paCO2-difference between right radial artery and postoxygenator ECMO circuit (variant 2) was 3.3 mmHg (95%-CI: 1.5–6.0 mmHg) and thereby significantly higher compared to variant 1 (p = 0.001). At the end of AT, paCO2-difference according to variant 1 remained unchanged with 1.1 mmHg (95%-CI: 0.9–1.8 mmHg). In contrast, paCO2-difference according to variant 2 increased to 9.9 mmHg (95%-CI: 3.5–19.2 mmHg; p = 0.002).
Simultaneous paCO2-analysis from right and left distal arterial lines is the method of choice to reduce the risk of adverse effects (e.g. severe respiratory acidosis) while performing AT in VA-ECMO patients during BD determination.
Abstract
Background
The concept of clinical ethics consultation (CECs) was implemented to provide support in ethical controversies in clinical settings and are offered in at least every second ...hospital in Germany. Neurological disorders often require complex decision-making. The aims of this study were to determine which situations lead to CEC in neurology and to investigate the influence of the individual patient’s wishes on the recommendation.
Methods
Standardised CEC protocols in the years 2011 to 2017 at the University Hospitals of Goettingen and Jena were retrospectively surveyed. The contents were categorised along existing protocol templates of CEC scenarios and subsequently paraphrased and reduced to significant meanings.
Results
27 CEC scenarios which were facilitated by various professional disciplines were reviewed. Stroke was the most frequent underlying condition. Nearly all patients were not able to consent. Mostly, the relatives acted as representatives or health advocates. In 67 % of cases, a sense of conflict triggered a CEC; in 33 % a sense of uncertainty was the reason for the CEC request. In 21 CEC scenarios, a recommendation was reached in consensus with all parties involved. In 59 % of cases, a decision was made to continue medical therapy. In seven cases, the patient’s wishes led to a limitation of therapy, while in just two cases this decision was made primarily relying on the patient’s best interest. In only 13 % of cases, a valid advance directive led to respective therapeutic consequences.
Conclusions
CEC is feasible for consensus-finding not only in conflicts, but also in situations of therapeutic uncertainty in neurology. There is a special importance of the patient’s wishes in decision-making in neurology. However, only in a few cases were advance directives precise and specific enough to have sufficient and decisive weight in therapeutic decision-making.
Background and Purpose
Coronavirus disease (COVID‐19) is still considered a global pandemic. The prognosis of COVID‐19 patients varies greatly. We aimed to assess the impact of preexisting, chronic ...neurological diseases (CNDs) and new‐onset acute neurological complications (ANCs) on the disease course, its complications, and outcomes.
Methods
We conducted a monocentric retrospective analysis from all hospitalized COVID‐19 patients between May 1, 2020 and January 31, 2021. Employing multivariable logistic regression models, we explored the association of CNDs and ANCs separately with hospital mortality and functional outcome.
Results
A total of 250 among 709 patients with COVID‐19 had CNDs. We found a 2.0 times higher chance of death (95% confidence interval CI: 1.37–2.92) for CND patients than for non‐CND patients. The chance for an unfavorable functional outcome (modified Rankin Scale > 3 at discharge) was 1.67 times higher in patients with CNDs than those without (95% CI: 1.07–2.59). Furthermore, 117 of all patients had 135 ANCs in total. We observed a 1.86 times higher chance to die (95% CI: 1.18–2.93) for patients with ANCs than without. The chance for a worse functional outcome was 3.6‐fold higher in ANC patients than without (95% CI: 2.22–6.01). Patients with CNDs had 1.73 times higher odds for developing ANCs (95% CI: 0.97–3.08).
Conclusion
Preexisting neurologic disorders or ANCs in COVID‐19 patients were associated with higher mortality and poorer functional outcome at discharge. Furthermore, development of acute neurologic complications was more frequent in patients with preexisting neurologic disease. Early neurological evaluation appears to be an important prognostic factor in COVID‐19 patients.

In 2021, three encephalitis cases due to the Borna disease virus 1 (BoDV-1) were diagnosed in the north and east of Germany. The patients were from the states of Thuringia, Saxony-Anhalt, and Lower ...Saxony. All were residents of known endemic areas for animal Borna disease but without prior diagnosed human cases. Except for one recently detected case in the state of Brandenburg, all >30 notified cases had occurred in, or were linked to, the southern state of Bavaria. Of the three detected cases described here, two infections were acute, while one infection was diagnosed retrospectively from archived brain autopsy tissue samples. One of the acute cases survived, but is permanently disabled. The cases were diagnosed by various techniques (serology, molecular assays, and immunohistology) following a validated testing scheme and adhering to a proposed case definition. Two cases were classified as confirmed BoDV-1 encephalitis, while one case was a probable infection with positive serology and typical brain magnetic resonance imaging, but without molecular confirmation. Of the three cases, one full virus genome sequence could be recovered. Our report highlights the need for awareness of a BoDV-1 etiology in cryptic encephalitis cases in all areas with known animal Borna disease endemicity in Europe, including virus-endemic regions in Austria, Liechtenstein, and Switzerland. BoDV-1 should be actively tested for in acute encephalitis cases with residence or rural exposure history in known Borna disease-endemic areas.
Abstract
Background
Botulinum neurotoxin (BoNT) is currently the best therapeutic option in the treatment for cervical dystonia (CD). Additional treatments like physiotherapy (PT) may even improve ...the results of the BoNT injection with type A (BoNT-A), but there are no definite recommendations. In the last few years, some studies showed tendencies for PT as an adjuvant therapy to benefit. However, high-quality studies are required.
Methods
This study is a multicentre, randomized, single-blind, controlled trial to demonstrate the effectiveness of a multimodal PT program compared to a nonspecific cupping therapy, additionally to the BoNT-A therapy. Two hundred participants will be assigned into the multimodal PT plus BoNT intervention arm or the BoNT plus cupping arm using randomization. Primary endpoint is the total Score of Toronto Western Spasmodic Rating Scale (TWSTRS). Secondary endpoints are the mobility of the cervical spine (range of motion, ROM), the TWSTRS subscales, and the quality of life (measured by questionnaires: CDQ-24 and SF-36). Patients will be single-blind assessed every 3 months according to their BoNT injection treatment over a period of 9 months.
Discussion
The study aims to determine the effectiveness and therefore potential benefit of an additional multimodal physiotherapy for standardized treatment with BoNT-A in patients with CD, towards the BoNT-therapy alone. This largest randomized controlled trial in this field to date is intended to generate missing evidence for therapy guidelines.
Trial registration
The study was registered in the German Clinical Study Register before the start of the patient recruitment (
DRKS00020411
; date: 21.01.2020).
Background and Objectives: Vaccine induced thrombotic thrombocytopenia (VITT) may occur after COVID-19 vaccination with recombinant adenoviral vector-based vaccines. VITT can present as cerebral ...sinus and venous thrombosis (CSVT), often complicated by intracranial hemorrhage. Today it is unclear, how long symptomatic VITT can persist. Here, we report the complicated long-term course of a VITT patient with extremely high titers of pathogenic anti-platelet factor 4 (PF4)-IgG antibodies. Methods: Clinical and laboratory findings are presented, including the course of platelet counts, D-Dimer levels, clinical presentation, imaging, SARS-CoV-2-serological and immunological, platelet activating anti-PF4-IgG, as well as autopsy findings. Results: The patient presented with extended superior sagittal sinus thrombosis with accompanying bifrontal intracerebral hemorrhage. Repeated treatment with intravenous immune globuline (IVIG) resolved recurrent episodes of thrombocytopenia. Moreover, the patient’s serum remained strongly positive for platelet-activating anti-PF4-IgG over three months. After a period of clinical stabilization, the patient suffered a recurrent and fatal intracranial hemorrhage. Conclusions: Complicated VITT with extremely high anti-PF4-IgG titers over three months can induce recurrent thrombocytopenia despite treatment with IVIG and anticoagulation. Plasma exchange, immunoadsorption, and /or immunosuppressive treatment may be considered in complicated VITT to reduce extraordinarily high levels of anti-PF4-IgG. Long-term therapy in such cases must take the individual bleeding risk and CSVT risk into account.
