Long-Term Survival After Single-Ventricle Palliation: A Swedish Nationwide Cohort Study.

Background: Long-term survival after single-ventricle palliation and the effect of dominant ventricle morphology in large, unselected series of patients are scarcely reported.

Methods And Results: This nationwide cohort study included all children undergoing operation with single-ventricle palliation during their first year of life in Sweden between January 1994 and December 2019. Data were obtained from institutional records and assessment of underlying cardiac anomaly and dominant ventricular morphology was based on complete review of medical records, surgical reports, and echocardiographic examinations.

Agreement and reliability of hepatic transient elastography in patients with chronic hepatitis C: A cross-sectional test-retest study.

Background And Aims: Transient elastography (TE) has largely replaced liver biopsy to evaluate fibrosis stage and cirrhosis in chronic hepatitis C. Previous studies have reported excellent reliability of TE but agreement metrics have not been reported. This study aimed to assess interrater agreement and reliability of repeated TE measurements.

Clinical Impression of Severity Index for Parkinson's Disease and Its Association to Health-Related Quality of Life.

Background: Clinical Impression of Severity Index for Parkinson's Disease (CISI-PD) is a simple tool that can easily be used in clinical practice. Few studies have investigated the relationship between health-related quality of life and the CISI-PD.

Objective: To analyze the association of CISI-PD scores with those of generic (EQ-5D-5L) and Parkinson's disease (PD) disease-specific (Parkinson's Disease Questionnaire-8 [PDQ-8]) health-related quality of life assessments.

Discriminative accuracy of the A/T/N scheme to identify cognitive impairment due to Alzheimer's disease.

Introduction: The optimal combination of amyloid-β/tau/neurodegeneration (A/T/N) biomarker profiles for the diagnosis of Alzheimer's disease (AD) dementia is unclear.

Methods: We examined the discriminative accuracy of A/T/N combinations assessed with neuroimaging biomarkers for the differentiation of AD from cognitively unimpaired (CU) elderly and non-AD neurodegenerative diseases in the TRIAD, BioFINDER-1 and BioFINDER-2 cohorts (total  = 832) using area under the receiver operating characteristic curves (AUC).

Results: For the diagnosis of AD dementia (vs.

Parkinsonism in Genetic Neurodevelopmental Disorders: A Systematic Review.

Background: With advances in clinical genetic testing, associations between genetic neurodevelopmental disorders and parkinsonism are increasingly recognized. In this review, we aimed to provide a comprehensive overview of reports on parkinsonism in genetic neurodevelopmental disorders and summarize findings related to genetic diagnosis, clinical features and proposed disease mechanisms.

Methods: A systematic literature review was conducted in PubMed and Embase on June 15, 2021.

Sodium-Glucose Co-Transporter Inhibitors and Atrial Fibrillation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background Sodium-glucose co-transporter (SGLT) inhibitors reduce cardiovascular outcomes including mortality in several populations; however, their effect on atrial fibrillation/flutter (AF) remains unclear. Our objective was to determine whether SGLT inhibitors reduce AF and whether a history of AF modifies the effect of SGLT inhibitors on the composite of heart failure hospitalization or cardiovascular death. Methods and Results We searched MEDLINE, Embase, and CENTRAL to March 2021.

Treatment of patients with Graves' disease in Sweden compared to international surveys of an 'index patient'.

Introduction: The treatment strategies for a 42-year-old female index patient with moderate Graves' disease (GD) vary according to several international surveys. The important question whether surveys of treatment preferences in theoretical patient cases also match how real patients are treated has not yet been addressed.

Materials And Methods: From a Swedish cohort of 1186 GD patients (TT-12 cohort), 27 women were identified using the same criteria as from the index patient surveys from the European and American Thyroid Associations.

Cerebrospinal fluid biomarker panel for synaptic dysfunction in Alzheimer's disease.

Introduction: Synaptic dysfunction and degeneration is one of the earliest events in Alzheimer's disease (AD) and the best correlate of cognitive decline. Thus, identification and validation of biomarkers reflecting synaptic degeneration to be used as prognostic biomarkers are greatly needed.

Method: Solid-phase extraction and parallel reaction monitoring mass spectrometry were used to quantify 17 synaptic proteins in CSF, in two cross-sectional studies including AD (n = 52) and controls (n = 37).

Challenges in Clinicogenetic Correlations: One Phenotype - Many Genes.

Background: In the field of movement disorders, what you see (phenotype) is seldom what you get (genotype). Whereas 1 phenotype was previously associated to 1 gene, the advent of next-generation sequencing (NGS) has facilitated an exponential increase in disease-causing genes and genotype-phenotype correlations, and the "one-phenotype-many-genes" paradigm has become prominent.

Objectives: To highlight the "one-phenotype-many-genes" paradigm by discussing the main challenges, perspectives on how to address them, and future directions.

Association Between ECG Abnormalities and Fatal Cardiovascular Disease Among Patients With and Without Severe Mental Illness.

Background ECG abnormalities are associated with adverse outcomes in the general population, but their prognostic significance in severe mental illness (SMI) remains unexplored. We investigated associations between no, minor, and major ECG abnormalities and fatal cardiovascular disease (CVD) among patients with SMI compared with controls without mental illness. Methods and Results We cross-linked data from Danish nationwide registries and included primary care patients with digital ECGs from 2001 to 2015.

The Prevalence and Determinants of Neuropsychiatric Symptoms in Late-Stage Parkinsonism.

Background: Late-stage parkinsonism and Parkinson's disease (PD) are insufficiently studied population. Although neuropsychiatric symptoms (eg, psychosis, depression, anxiety, behavioral problems) are frequently present, their prevalence and clinical predictors remain unknown.

Objective: To determine the prevalence and predictors of neuropsychiatric symptoms in late-stage PD.

Proliferation and benevolence-A framework for dissecting the mechanisms of microbial virulence and health promotion.

Key topics in the study of host-microbe interactions-such as the prevention of drug resistance and the exploitation of beneficial effects of bacteria-would benefit from concerted efforts with both mechanistic and evolutionary approaches. But due to differences in intellectual traditions, insights gained in one field rarely benefit the other. Here, we develop a conceptual and analytical framework for the integrated study of host-microbe interactions.

Survival benefits from concomitant chemoradiotherapy before radical surgery in stage IVA sinonasal mucosal melanoma?

Background: The aim of the study was to review a local treatment protocol for sinonasal mucosal melanoma (SNMM) focusing on triple modality treatment (TMT), that is, neoadjuvant concomitant chemoradiotherapy (CRT) and surgery.

Methods: In a retrospective design, data on clinical presentation, treatment, and survival were retrieved for 22 consecutive patients from a tertiary referral center.

Results: The mean overall survival (OS) for all patients (3 stage III, 16 stage IVA, and 3 stage IVB) was 62 months, and the 5-year OS rate 50%.

Dietary Pattern Specific Protein Biomarkers for Cardiovascular Disease: A Cross-Sectional Study in 2 Independent Cohorts.

Background Mechanisms related to the influence of diet on the development of cardiovascular disease are not entirely understood, and protein biomarkers may help to understand these pathways. Studies of biomarkers identified with multiplex proteomic methods and dietary patterns are largely lacking. Methods and Results Dietary patterns were generated through principal component analysis in 2 population-based Swedish cohorts, the EpiHealth (EpiHealth study; n=20 817 men and women) and the SMCC (Swedish Mammography Cohort Clinical [n=4650 women]).

CSF placental growth factor - a novel candidate biomarker of frontotemporal dementia.

Objective: Diagnosis of frontotemporal dementia (FTD) is complicated by the overlap of clinical symptoms with other dementia disorders. Development of robust fluid biomarkers is critical to improve the diagnostic work-up of FTD.

Methods: CSF concentrations of placental growth factor (PlGF) were measured in the discovery cohort including patients with FTD ( = 27), Alzheimer disease (AD) dementia ( = 75), DLB or PDD ( = 47), subcortical vascular dementia (VaD,  = 33), mild cognitive impairment that later converted to AD (MCI-AD,  = 34), stable MCI (sMCI,  = 62), and 50 cognitively healthy controls from the Swedish BioFINDER study.

Acute stroke alert activation, emergency service use, and reperfusion therapy in Sweden.

Objectives: Ambulance services and stroke alerts reduce the time from stroke onset to acute stroke diagnosis. We describe the use of stroke alerts and ambulance services in different hospitals and patient groups and their relationship with reperfusion therapy.

Methods: This nationwide study included 49,907 patients admitted with acute stroke who were registered in The Swedish Stroke Register (Riksstroke) in 2011-2012.

Tau oligomers in cerebrospinal fluid in Alzheimer's disease.

Objective: With an increasing incidence of Alzheimer's disease (AD) and neurodegenerative tauopathies, there is an urgent need to develop reliable biomarkers for the diagnosis and monitoring of the disease, such as the recently discovered toxic tau oligomers. Here, we aimed to demonstrate the presence of tau oligomers in the cerebrospinal fluid (CSF) of patients with cognitive deficits, and to determine whether tau oligomers could serve as a potential biomarker for AD.

Methods: A multicentric collaborative study involving a double-blinded analysis with a total of 98 subjects with moderate to severe AD ( = 41), mild AD ( = 31), and nondemented control subjects ( = 26), and two pilot studies of 33 total patients with AD ( = 19) and control ( = 14) subjects were performed.

Protocol for meta-analysis of temperature reduction in animal models of cardiac arrest.

Targeted temperature management (TTM) of 32-34 °C has been the standard treatment for out-of-hospital cardiac arrest since clinical trials in 2002 showed benefits to survival and neurological outcome. Recently, this treatment has been challenged by another clinical trial showing no difference in outcome between TTM of 33 °C and 36 °C. This protocol describes the methodology for a meta-analysis detailing temperature-reducing interventions to treat global ischaemia in animal models.

Mitochondrial Respiratory Function in Peripheral Blood Cells from Huntington's Disease Patients.

Background: Patients with Huntington's disease display symptoms from both the central nervous system and peripheral tissues. Mitochondrial dysfunction has been implicated as part of the pathogenesis of the disease and has been reported in brain tissue and extracerebral tissues, such as muscle and blood cells, but the results are inconsistent. Therefore, the authors performed a refined evaluation of mitochondrial function in 2 types of peripheral blood cells from 14 patients with Huntington's disease and 21 control subjects.

Cerebrospinal fluid neurogranin and YKL-40 as biomarkers of Alzheimer's disease.

Objective: Widespread implementation of cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD) in clinical settings requires improved accuracy for diagnosis of prodromal disease and for distinguishing AD from non-AD dementias. Novel and promising CSF biomarkers include neurogranin, a marker of synaptic degeneration, and YKL-40, a marker of neuroinflammation.

Methods: CSF neurogranin and YKL-40 were measured in a cohort of 338 individuals including cognitively healthy controls and patients with stable mild cognitive impairment (sMCI), MCI who later developed AD (MCI-AD), AD dementia, Parkinson's disease dementia (PDD), dementia with Lewy bodies (DLB), vascular dementia (VaD), and frontotemporal dementia (FTD).
