Abstract

The aim of awake brain surgery is to perform a maximum resection on the one hand, and to preserve cognitive functions, quality of life and personal autonomy on the other hand. Historically, language and sensorimotor functions were most frequently monitored. Over the years other cognitive functions, including music, have entered the operation theatre. Cases about monitoring musical abilities during awake brain surgery are emerging, and a systematic method how to monitor music would be the next step. According to the IDEAL framework for surgical innovations our study aims to present future recommendation based on a systematic literature search (PRISMA) in combination with lessons learned from three case reports from our own clinical practice with professional musicians (n = 3). We plead for structured procedures including individual tailored tasks. By embracing these recommendations, we can both improve clinical care and unravel music functions in the brain.

Abstract

BACKGROUND: Patients with brain tumours are increasingly treated by using the awake craniotomy technique. Some patients may experience anxiety when subjected to brain surgery while being fully conscious. However, there has been only limited research into the extent to which such surgeries actually result in anxiety or other psychological complaints. Previous research suggests that undergoing awake craniotomy surgery does not lead to psychological complaints, and that post-traumatic stress disorders (PTSD) are uncommon following this type of surgery. It must be noted, however, that many of these studies used small random samples.METHOD: In the current study, 62 adult patients completed questionnaires to identify the degree to which they experienced anxiety, depressive and post-traumatic stress complaints following awake craniotomy using an awake-awake-awake procedure. All patients were cognitively monitored and received coaching by a clinical neuropsychologist during the surgery.RESULTS: In our sample, 21% of the patients reported pre-operative anxiety. Four weeks after surgery, 19% of the patients reported such complaints, and 24% of the patients reported anxiety complaints after 3 months. Depressive complaints were present in 17% (pre-operative), 15% (4 weeks post-operative) and 24% (3 months post-operative) of the patients. Although there were some intra-individual changes (improvement or deterioration) in the psychological complaints over time, on group-level postoperative levels of psychological complaints were not increased relative to the preoperative level of complaints. The severity of post-operative PTSD-related complaints were rarely suggestive of a PTSD. Moreover, these complaints were seldom attributed to the surgery itself, but appeared to be more related to the discovery of the tumour and the postoperative neuropathological diagnosis.CONCLUSIONS: The results of the present study do not indicate that undergoing awake craniotomy i

Abstract

BACKGROUND: The purpose of awake brain tumor surgery is to maximize the resection of the tumor and to minimize the risk of neurological and cognitive impairments. The aim of this study is to gain understanding of the development of possible postoperative cognitive deficits after awake brain tumor surgery in patients with suspected gliomas, by comparing preoperative, early postoperative, and late postoperative functioning. A more detailed timeline will be helpful in informing candidates for surgery about what to expect regarding their cognitive functioning.METHODS: Thirty-seven patients were included in this study. Cognitive functioning was measured by means of a broad cognitive screener preoperatively, days after surgery and months after surgery in patients who underwent awake brain tumor surgery with cognitive monitoring. The cognitive screener included tests for object naming, reading, attention span, working memory, inhibition, inhibition/switching, and visuoperception. We performed a Friedman ANOVA to analyze on group level.RESULTS: Overall, no significant differences were found between preoperative cognitive functioning, early postoperative cognitive functioning, and late postoperative cognitive functioning, except for performances on the inhibition task. Directly after surgery, patients were significantly slower on this task. However, in the following months after surgery, they returned to their preoperative level.CONCLUSION: The timeline of cognitive functioning after awake tumor surgery appeared overall stable in the early and late postoperative phase, except for inhibition, which is more difficult in the first days after awake brain tumor surgery. This more detailed timeline of cognitive functioning, in combination with future research, can possibly be contributing in informing patients and caregivers what to expect after awake brain tumor surgery.

Abstract

Background Since the emergence of SARS-CoV-2, evolutionary pressure has driven large increases in the transmissibility of the virus. However, with increasing levels of immunity through vaccination and natural infection the evolutionary pressure will switch towards immune escape. Genomic surveillance in regions of high immunity is crucial in detecting emerging variants that can more successfully navigate the immune landscape. Methods We present phylogenetic relationships and lineage dynamics within England (a country with high levels of immunity), as inferred from a random community sample of individuals who provided a self-administered throat and nose swab for rt-PCR testing as part of the REal-time Assessment of Community Transmission-1 (REACT-1) study. During round 14 (9 September–27 September 2021) and 15 (19 October–5 November 2021) lineages were determined for 1322 positive individuals, with 27.1% of those which reported their symptom status reporting no symptoms in the previous month. Results We identified 44 unique lineages, all of which were Delta or Delta sub-lineages, and found a reduction in their mutation rate over the study period. The proportion of the Delta sub-lineage AY.4.2 was increasing, with a reproduction number 15% (95% CI 8–23%) greater than the most prevalent lineage, AY.4. Further, AY.4.2 was less associated with the most predictive COVID-19 symptoms (p = 0.029) and had a reduced mutation rate (p = 0.050). Both AY.4.2 and AY.4 were found to be geographically clustered in September but this was no longer the case by late October/early November, with only the lineage AY.6 exhibiting clustering towards the South of England. Conclusions As SARS-CoV-2 moves towards endemicity and new variants emerge, genomic data obtained from random community samples can augment routine surveillance data without the potential biases introduced due to higher sampling rates of symptomatic individuals.

Abstract

The spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical for virus infection through the engagement of the human ACE2 protein1 and is a major antibody target. Here we show that chronic infection with SARS-CoV-2 leads to viral evolution and reduced sensitivity to neutralizing antibodies in an immunosuppressed individual treated with convalescent plasma, by generating whole-genome ultra-deep sequences for 23 time points that span 101 days and using in vitro techniques to characterize the mutations revealed by sequencing. There was little change in the overall structure of the viral population after two courses of remdesivir during the first 57 days. However, after convalescent plasma therapy, we observed large, dynamic shifts in the viral population, with the emergence of a dominant viral strain that contained a substitution (D796H) in the S2 subunit and a deletion (ΔH69/ΔV70) in the S1 N-terminal domain of the spike protein. As passively transferred serum antibodies diminished, viruses with the escape genotype were reduced in frequency, before returning during a final, unsuccessful course of convalescent plasma treatment. In vitro, the spike double mutant bearing both ΔH69/ΔV70 and D796H conferred modestly decreased sensitivity to convalescent plasma, while maintaining infectivity levels that were similar to the wild-type virus.The spike substitution mutant D796H appeared to be the main contributor to the decreased susceptibility to neutralizing antibodies, but this mutation resulted in an infectivity defect. The spike deletion mutant ΔH69/ΔV70 had a twofold higher level of infectivity than wild-type SARS-CoV-2, possibly compensating for the reduced infectivity of the D796H mutation. These data reveal strong selection on SARS-CoV-2 during convalescent plasma therapy, which is associated with the emergence of viral variants that show evidence of reduced susceptibility to neutralizing antibodies in immunosuppressed individuals.

Abstract

The evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus leads to new variants that warrant timely epidemiological characterization. Here we use the dense genomic surveillance data generated by the COVID-19 Genomics UK Consortium to reconstruct the dynamics of 71 different lineages in each of 315 English local authorities between September 2020 and June 2021. This analysis reveals a series of subepidemics that peaked in early autumn 2020, followed by a jump in transmissibility of the B.1.1.7/Alpha lineage. The Alpha variant grew when other lineages declined during the second national lockdown and regionally tiered restrictions between November and December 2020. A third more stringent national lockdown suppressed the Alpha variant and eliminated nearly all other lineages in early 2021. Yet a series of variants (most of which contained the spike E484K mutation) defied these trends and persisted at moderately increasing proportions. However, by accounting for sustained introductions, we found that the transmissibility of these variants is unlikely to have exceeded the transmissibility of the Alpha variant. Finally, B.1.617.2/Delta was repeatedly introduced in England and grew rapidly in early summer 2021, constituting approximately 98% of sampled SARS-CoV-2 genomes on 26 June 2021.

Abstract

Transmission of SARS-CoV-2 is uncontrolled in many parts of the world; control is compounded in some areas by the higher transmission potential of the B.1.1.7 variant1, which has now been reported in 94 countries. It is unclear whether the response of the virus to vaccines against SARS-CoV-2 on the basis of the prototypic strain will be affected by the mutations found in B.1.1.7. Here we assess the immune responses of individuals after vaccination with the mRNA-based vaccine BNT162b22. We measured neutralizing antibody responses after the first and second immunizations using pseudoviruses that expressed the wild-type spike protein or a mutated spike protein that contained the eight amino acid changes found in the B.1.1.7 variant. The sera from individuals who received the vaccine exhibited a broad range of neutralizing titres against the wild-type pseudoviruses that were modestly reduced against the B.1.1.7 variant. This reduction was also evident in sera from some patients who had recovered from COVID-19. Decreased neutralization of the B.1.1.7 variant was also observed for monoclonal antibodies that target the N-terminal domain (9 out of 10) and the receptor-binding motif (5 out of 31), but not for monoclonal antibodies that recognize the receptor-binding domain that bind outside the receptor-binding motif. Introduction of the mutation that encodes the E484K substitution in the B.1.1.7 background to reflect a newly emerged variant of concern (VOC 202102/02) led to a more-substantial loss of neutralizing activity by vaccine-elicited antibodies and monoclonal antibodies (19 out of 31) compared with the loss of neutralizing activity conferred by the mutations in B.1.1.7 alone. The emergence of the E484K substitution in a B.1.1.7 background represents a threat to the efficacy of the BNT162b2 vaccine.

Abstract

Syphilis, which is caused by the sexually transmitted bacterium Treponema pallidum subsp. pallidum, has an estimated 6.3 million cases worldwide per annum. In the past ten years, the incidence of syphilis has increased by more than 150% in some high-income countries, but the evolution and epidemiology of the epidemic are poorly understood. To characterize the global population structure of T. pallidum, we assembled a geographically and temporally diverse collection of 726 genomes from 626 clinical and 100 laboratory samples collected in 23 countries. We applied phylogenetic analyses and clustering, and found that the global syphilis population comprises just two deeply branching lineages, Nichols and SS14. Both lineages are currently circulating in 12 of the 23 countries sampled. We subdivided T. p. pallidum into 17 distinct sublineages to provide further phylodynamic resolution. Importantly, two Nichols sublineages have expanded clonally across 9 countries contemporaneously with SS14. Moreover, pairwise genome analyses revealed examples of isolates collected within the last 20 years from 14 different countries that had genetically identical core genomes, which might indicate frequent exchange through international transmission. It is striking that most samples collected before 1983 are phylogenetically distinct from more recently isolated sublineages. Using Bayesian temporal analysis, we detected a population bottleneck occurring during the late 1990s, followed by rapid population expansion in the 2000s that was driven by the dominant T. pallidum sublineages circulating today. This expansion may be linked to changing epidemiology, immune evasion or fitness under antimicrobial selection pressure, since many of the contemporary syphilis lineages we have characterized are resistant to macrolides.

Abstract

Background: Syphilis is an important sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The last two decades have seen syphilis incidence rise in many high-income countries, yet the evolutionary and epidemiological relationships that underpin this are poorly understood, as is the global T. pallidum population structure. Methods: We assembled a geographically and temporally diverse collection of clinical and laboratory samples, performing direct sequencing on the majority, and combining these with 133 publicly available sequences to compile a dataset comprising 726 T. pallidum genomes. We analysed the resulting genomes using detailed phylogenetic analysis and clustering. Results: We show that syphilis globally can be described by only two deeply branching lineages, Nichols and SS14. We show that both of these lineages can be found circulatingcon currently in 12 of the 23 countries sampled. To provide further phylodynamic resolution we subdivided Treponema pallidum subspecies pallidum into 17 distinct sublineages. Importantly, like SS14, we provide evidence that two Nichols sublineages have expanded clonally across 9 countries contemporaneously with SS14. Moreover, pairwise genome analysis showed that recent isolates circulating in 14 different countries were genetically identical in their core genome to those from other countries, suggesting frequent exchange through international transmission pathways. This contrasts with the majority of samples collected prior to 1983, which are phylogenetically distinct from these more recently isolated sublineages. Bayesian temporal analysis provided evidence of a population bottleneck and decline occurring during the late 1990s, followed by a rapid population expansion a decade later. This was driven by the dominant T. pallidum sublineages circulating today, many of which are resistant to macrolides. Conclusion: Combined we show that the population of contemporary syphilis in high-inco

Abstract

Purpose Deficits in neurocognitive functioning (NCF) frequently occur in glioma patients. Both treatment and the tumor itself contribute to these deficits. In order to minimize the harmful effects of surgery, an increasing number of patients undergo awake craniotomy. To investigate whether we can indeed preserve cognitive functioning after state-of-the art awake surgery and to identify factors determining postoperative NCF, we performed a retrospective cohort study. Methods In diffuse glioma (WHO grade 2–4) patients undergoing awake craniotomy, we studied neurocognitive functioning both pre-operatively and 3–6 months postoperatively. Evaluation covered five neurocognitive domains. We performed analysis of data on group and individual level and evaluated the value of patient-, tumor- and treatment-related factors for predicting change in NCF, using linear and logistic regression analysis. Results We included 168 consecutive patients. Mean NCF-scores of psychomotor speed and visuospatial functioning significantly deteriorated after surgery. The percentage of serious neurocognitive impairments (− 2 standard deviations) increased significantly for psychomotor speed only. Tumor involvement in the left thalamus predicted a postoperative decline in NCF for the domains overall-NCF, executive functioning and psychomotor speed. An IDH-wildtype status predicted decline for overall-NCF and executive functioning. Conclusions In all cognitive domains, except for psychomotor speed, cognitive functioning can be preserved after awake surgery. The domain of psychomotor speed seems to be most vulnerable to the effects of surgery and early postoperative therapies. Cognitive performance after glioma surgery is associated with a combination of structural and biomolecular effects from the tumor, including IDH-status and left thalamic involvement.

Abstract

Background: Cognitive assessment during awake brain tumor surgery is used to maximize the extent of tumor resection while minimizing the risk of cognitive damage in patients. Assessments of language functions are widely reported while other cognitive domains are underexposed. In this study, the current cognitive screener that is used at the UMC Utrecht Department of Neurosurgery is expanded to monitor a broader spectrum of cognitive domains. Furthermore, parallel versions have been made to assess cognitive functioning over time. Methods: Four cognitive screeners were administrated to healthy Dutch individuals (N=38). Each version tapped different domains: language (object naming, reading), executive functioning and attention (Stroop Test with and without Block), working memory (Digit Span Forward and Backwards), visual perception (Dot Counting Test with Background) and emotion recognition (How are They Feeling?: Colorcards). One way ANOVA and Kruskal-Wallis analysis were performed to determine significant group differences. Results: No significant differences between groups in the Stroop Test without Block (p=.025), Digit Span Forward (p=.531) and Backwards (p=.079), Reading (words/sentences) and Dot Counting Test were found. Significant differences between groups were found for the Snodgrass Naming Task between two versions (p=.017) and How are They Feeling?: Colorcards (p=.000). Conclusion: This study demonstrated the possibility to expand the cognitive screener and conducting reliable parallel versions to monitor cognitions in multiple timeframes, considering no significant differences between versions have been found in the majority of neuropsychological tests. This provide insight in which domains extensive test assessments is needed for optimal patient care. Investigations into an emotion recognition task is desired

Abstract

The BADS is a widely used neuropsychological test battery with a high ecological validity. However, the current Dutch normative data dates back 30 years and several practical issues have arisen. The aims of this study were twofold: performing an extensive evaluation of the time limits of several BADS subtests, and providing new and improved Dutch normative tables for the BADS. It was hypothesized that older participants would need more time to complete the subtests than younger participants, uncovering the need for separate time limits for different age groups. In total, 121 healthy participants were included in this study and divided equally into four groups: Young Adults, Middle-aged Adults, Older Adults, and Elderly. Elderly generally needed more time than the other groups to complete several of the subtests, reaching statistical significance for the Rule Shift Cards, Action Program, and most Zoo Map time variables. However, the majority of Elderly did not violate the current time limits, making Elderly-specific time limits seem unnecessary. Young Adults completed the subtests remarkably faster and without violations. Thus, perhaps the time limits should be stricter for Young Adults, instead of more lenient for Elderly. The new norms were compared with the current norms, demonstrating several significant higher means for the new data. With two clinical cases it was illustrated that the new normative data provides stricter classifications of performances. Overall, this study indicates the need for more extensive research into the current time limits and new Dutch normative data of the BADS

Abstract

Objective Awake surgery emerges as a standard of care for brain tumors located in or near eloquent areas. Levels of preoperative anxiety in patients are important, because anxiety can influence cognitive performance and participation, hence altering the outcome of the procedure. In this study we analyzed the prevalence and potential clinical predictors of anxiety in the pre-operative phase of an awake brain tumor surgery. Patients and methods Seventy consecutive candidates for an awake brain tumor surgery were included. All patients received a neuropsychological pre-operative work-up. The Hospital Anxiety and Depression Scale (HADS) was administrated to investigate symptoms of anxiety. Demographic and medical data were extracted from patients’ charts. Linear regression analyses, multiple regression analyses, t-tests for parametric and Mann-Whitney U tests for non-parametric data were used to analyze the relation between demographic and medical variables and pre-operative anxiety. Results Mean score on the anxiety scale of the HADS was 6.1 (SD = 4.2, range 1–19) and 25% of the patients scored on or above the cut-off for anxiety symptoms (score >7). Women reported higher levels of anxiety than men (p < 0.01). Furthermore, younger patient were more anxious than older patients (p < 0.05). No other variables were significantly related to pre-operative anxiety. Conclusions Merely, one in every four patients reported significant anxiety symptoms in the pre-operative phase. Besides gender and age, none of the other demographic or medical factors were significantly associated with the level of anxiety.

Abstract

This work aimed to manufacture scaffolds from a hydrogel composed of a sodium alginate matrix with hydroxyapatite reinforcements using a 3D bioprinter, aiming at application in bone tissue regeneration. The alginate solution was prepared by dissolving sodium alginate at a concentration of 10% (w/v). Hydroxyapatite (HAp) was added to the solution at 2.5% and 5.0% (w/v) concentrations, followed by placing the samples in a container with a 1.0% (w/v) calcium chloride solution. The scaffolds were analyzed for HAp concentration and morphological characteristics, physicochemical properties, and biological response. The scaffolds show reproducibility and spectroscopic analyses confirm hydrogel formation and hydroxyapatite incorporation in the alginate matrix. The hydrophilic properties are compatible with scaffolds obtained through 3D printing made from polysaccharides, and the thermal analysis showed the expected behavior of these same materials. Preliminary findings indicated that scaffolds containing 2.5% (w/v) hydroxyapatite are inside cytotoxicity limit (66.4 ± 7.0%) towards canine E20 lineage cells. In contrast, scaffolds with 0% and 5.0% (w/v) hydroxyapatite were non-cytotoxic. Notably, the latter scaffold demonstrated enhanced cell proliferation, as anticipated, owing to the hydrophilic properties of alginate that enable easy and swift cell seeding, facilitating nutrient transport and cellular growth within the scaffold.

In dit artikel wordt vanuit specialistisch oogpunt ingegaan op deze verschillende neuropsychologische aspecten, zonder een 'receptuur' te willen geven van een ideale testbatterij dan wel afkappunten voor het bepalen van grenzen. Binnen onder andere de werkgroep wakkere OK (WOK) wordt gewerkt aan het tot stand brengen van richtlijnen die als handvat kunnen dienen en richting kunnen geven aan kwalitatief goede zorg en een basis kunnen vormen voor wetenschappelijke onderbouwing van wakkere hersenoperaties.

Abstract

Neuropsychology is a rapidly growing, independent discipline with a broad work field. Neuropsychologists are working in hospitals, rehabilitation centres, nursing homes, forensic organisations and research institutes. One of the most important instruments of a neuropsychologist in assessing the behavioural expression of brain functions is the neuropsychological examination. This examination can have different purposes: 1. Diagnosis 2. Patient care 3. Treatment 4. Research The aim of this thesis is to demonstrate the diversity of the purposes of a neuropsychological examination. I will do this by presenting a series of studies that reflect these different purposes. Chapter 2 and chapter 3 will describe the neuropsychological examination as a diagnostic tool in two case studies. Chapter 4 and chapter 5 discuss different aspects of the neuropsychological examination in patient care. Chapter 6 illustrates the neuropsychological examination as a manner to evaluate treatment. Chapter 7, 8 and 9 are examples of the neuropsychological examination in research. In Chapter 10, the General Discussion, we question whether the different purposes of a neuropsychological examination should be seen as isolated aspects. As neuropsychologists, we aim the most optimal use of our neuropsychological assessment. Should we therefore not continuously keep other purposes as the one defined in the referral question in mind as well? Combining different purposes in one neuropsychological examination can be described as a multipurpose examination. A multipurpose examination makes us aware of other possible purposes of the neuropsychological examination than originally determined. The multipurpose examination, or in other words a multifaceted approach, forces us to think outside the standard boundaries of our assessment and outside the original reason for referral. In daily practice, the combination between the different purposes, or in other words between research and clinical care, is not always made. This can be the result of limited time and financial resources, but also simply because we are not used to it. First of all, in the curriculum of neuropsychologists in the Netherlands, the integration of different purposes is not consistently made. Clinical care and research are artificially separated in different stages of the education system and only in a very late stadium reunited. By combining clinical and research topics consequently in all stages of the neuropsychological educational program, neuropsychologists will be automatically more willing to integrate aspects of clinical care and research. Furthermore, in the broad profession of neuropsychology, some neuropsychologists are still working in isolation. This may have several drawbacks. The diagnosis and treatment procedures are viewed as fragmented and the results of the neuropsychological examination are therefore not always optimally used. Furthermore, interesting cases for research will be missed because neuropsychologists working in clinical settings are not in contact with those who are participating in research. Short lines between hospitals, rehabilitation centres, nursing homes and research institutes will be helpful in combining the different purposes. Finally, standards of evidence-based methods can be illustrative in combining research and clinical care (and integrating the four purposes described by Lezak). This thesis makes neuropsychologists more aware of the different purposes of a neuropsychological examination. Being aware of these different purposes can be helpful in looking outside the standard boundaries of your profession. As a result neuropsychology will rise to a higher level.

Abstract

The Symptom Checklist 90–Revised (SCL-90-R) is an international, widely used, self-report questionnaire of multidimensional complaints with normative data for healthy control subjects and psychiatric patients. The questionnaire is also often used in neurological patients. Little is known about the amount and pattern of complaints in this group, and normative data are lacking. We therefore analyzed self-reported symptoms on the SCL-90-R of a neurological population (N = 600). Moreover, we compared the answer patterns of five subgroups: neurodegenerative disease, cerebrovascular disease, epilepsy, brain tumor, and traumatic brain injury. Neurological outpatients scored significantly higher in comparison with normative data from healthy control subjects, with most pronounced scores on Inadequacy of Thinking and Acting, Depression, and Somatization (p < .01, effect sizes 1.69, 0.83, and 0.83). No differences between the various pathologies were found. Although it is difficult to determine whether the complaints arise directly from the neurological disease or more indirectly from psychiatric disturbances accompanying the disease, simply comparing a neurological patient to normative data for healthy control subjects can lead to inappropriate classifications. Complaints of our patients should not be directly interpreted as psychopathology. A two-step procedure in which scores on the SCL-90-R are first compared to healthy control subjects and secondly to neurological patients can be helpful in the interpretation.

Abstract

Item does not contain fulltext, Impairments in executive functioning frequently occur after acquired brain damage, in psychiatric disorders, and in relation to aging. The Brixton Spatial Anticipation Test is a relatively new measure for assessing the ability to detect and follow a rule, an important aspect of executive functioning. To date, normative data on this task are limited, particularly concerning the elderly. This study presents age- and education-adjusted regression-based norms obtained in a group of healthy older participants (n = 283; mean age 67.4 +/- 8.5 years). The applicability and validity of these norms were further examined in different groups of patients with stroke (n = 106), diabetes mellitus (n = 376), MCI/early dementia (n = 70), psychiatric disorders (n = 63), and Korsakoff's syndrome (n = 41). The results showed that patients with Korsakoff's syndrome, stroke, and psychiatric disorders performed significantly worse than healthy controls. Test-retest correlation (n = 83), learning effects, and correlations with other neuropsychological tests were also explored. Based on the present study, the Brixton test appears a useful addition to existing measures of executive functioning. Moreover, the test can be reliably applied in different groups of clinical patients.
