SARS-CoV-2 N protein recruits G3BP to double membrane vesicles to promote translation of viral mRNAs.

Ras-GTPase-activating protein SH3-domain-binding proteins (G3BP) are critical for the formation of stress granules (SGs) through their RNA- and ribosome-binding properties. SARS-CoV-2 nucleocapsid (N) protein exhibits strong binding affinity for G3BP and inhibits infection-induced SG formation soon after infection. To study the impact of the G3BP-N interaction on viral replication and pathogenesis in detail, we generated a mutant SARS-CoV-2 (RATA) that specifically lacks the G3BP-binding motif in the N protein.

Design: Systematic review and meta-analysis with meta-regression.

Data Sources: The Cochrane Central Register of Controlled Trials, PubMed, MEDLINE, Embase, SPORTDiscus, PsycINFO, Scopus and Web of Science were searched without language restrictions from inception to 13 September2022 (PROSPERO registration no CRD42020210651).

Real-World Data on Potent P2Y12 Inhibition in Patients with Suspected Chronic Coronary Syndrome, Referred for Coronary Angiography.

Introduction: Potential benefit with potent platelet inhibition in patients with chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI) has been discussed. The aim of this study was to compare a potent P2Y12 inhibition strategy using ticagrelor with clopidogrel in CCS patients referred for coronary angiography (CA) and PCI if feasible.

Methods: In this retrospective real-world study, patients referred for outpatient CA due to suspected CCS were included.

Managing surgery in hemophilia with recombinant factor VIII Fc and factor IX Fc: Data on safety and effectiveness from phase 3 pivotal studies.

Background: Surgical procedures impose hemostatic risk to people with hemophilia, which may be minimized by optimal factor (F) replacement therapy.

Methods: This analysis evaluates the efficacy and safety of extended half-life factor replacement recombinant FVIII and FIX Fc fusion proteins (rFVIIIFc and rFIXFc) during surgery in phase 3 pivotal (A-LONG/Kids A-LONG and B-LONG/Kids B-LONG) and extension (ASPIRE and B-YOND) studies. Dosing regimens were determined by investigators.

Transradial versus trans-femoral access site in high-speed rotational atherectomy in Sweden.

Background: Radial artery is the preferred access site in contemporary percutaneous coronary intervention (PCI). However, limited data exist regarding utilization pattern, safety, and long-term efficacy of transradial artery access (TRA) PCI in heavily calcified lesions using high-speed rotational atherectomy (HSRA).

Methods: All patients who underwent HSRA-PCI in Sweden between 2005 and 2016 were included.

Survival and level of care among breast cancer patients with brain metastases treated with whole brain radiotherapy.

Purpose: The benefit of whole brain radiotherapy (WBRT) for late stage breast cancer patients with brain metastases has been questioned. In this study we evaluated survival and level of care (hospital or home) following WBRT in a population-based cohort by personal and tumor characteristics.

Methods: We identified 241 consecutive patients with breast cancer and brain metastases receiving WBRT in Stockholm, Sweden, 1999-2012.

Time to review the gold standard for genotyping vancomycin-resistant enterococci in epidemiology: Comparing whole-genome sequencing with PFGE and MLST in three suspected outbreaks in Sweden during 2013-2015.

Vancomycin-resistant enterococci (VRE) are a challenge to the health-care system regarding transmission rate and treatment of infections. VRE outbreaks have to be controlled from the first cases which means that appropriate and sensitive genotyping methods are needed. The aim of this study was to investigate the applicability of whole genome sequencing based analysis compared to Pulsed-Field Gel Electrophoresis (PFGE) and Multi-Locus Sequence Typing (MLST) in epidemiological investigations as well as the development of a user friendly method for daily laboratory use.

Treatment Restarting After Discontinuation of Adjuvant Hormone Therapy in Breast Cancer Patients.

Background: Over half of breast cancer patients discontinue their adjuvant hormone therapy, permanently or temporarily. We aimed to identify predictors of treatment restarting after discontinuation of adjuvant hormone therapy and to test the hypothesis that treatment restarting is associated with better breast cancer outcomes.

Methods: We conducted a population-based cohort study by linking data from the Stockholm-Gotland Breast Cancer Register, the Swedish Prescribed Drug Register, and a self-reported questionnaire.

Parent of Origin and Prognosis in Familial Breast Cancer in Sweden.

Background: It has been suggested that prognosis in familial breast cancer could be influenced by the parent of origin, with a worse prognosis when inherited paternally. This study aimed to investigate the effect of the parent of origin on prognosis.

Patients And Methods: Index patients were divided into two study groups depending on the parent of origin.

The Second Spiking Threshold: Dynamics of Laminar Network Spiking in the Visual Cortex.

Most neurons have a threshold separating the silent non-spiking state and the state of producing temporal sequences of spikes. But neurons in vivo also have a second threshold, found recently in granular layer neurons of the primary visual cortex, separating spontaneous ongoing spiking from visually evoked spiking driven by sharp transients. Here we examine whether this second threshold exists outside the granular layer and examine details of transitions between spiking states in ferrets exposed to moving objects.

Resignation Syndrome: Catatonia? Culture-Bound?

Resignation syndrome (RS) designates a long-standing disorder predominately affecting psychologically traumatized children and adolescents in the midst of a strenuous and lengthy migration process. Typically a depressive onset is followed by gradual withdrawal progressing via stupor into a state that prompts tube feeding and is characterized by failure to respond even to painful stimuli. The patient is seemingly unconscious.

Management of latent Mycobacterium tuberculosis infection: WHO guidelines for low tuberculosis burden countries.

Latent tuberculosis infection (LTBI) is characterised by the presence of immune responses to previously acquired Mycobacterium tuberculosis infection without clinical evidence of active tuberculosis (TB). Here we report evidence-based guidelines from the World Health Organization for a public health approach to the management of LTBI in high risk individuals in countries with high or middle upper income and TB incidence of <100 per 100 000 per year. The guidelines strongly recommend systematic testing and treatment of LTBI in people living with HIV, adult and child contacts of pulmonary TB cases, patients initiating anti-tumour necrosis factor treatment, patients receiving dialysis, patients preparing for organ or haematological transplantation, and patients with silicosis.

Clinical characteristics and quality-of-life in patients surviving a decade of prostate cancer with bone metastases.

Objective: To describe characteristics and quality-of-life (QoL), and to define factors associated with long-term survival in a subgroup of patients with prostate cancer with M1b disease.

Patients And Methods: The study was based on 915 patients from a prospective randomised multicentre trial (No. 5) by the Scandinavian Prostate Cancer Group, comparing parenteral oestrogen with total androgen blockade.

A computational investigation of feedforward and feedback processing in metacontrast backward masking.

In human perception studies, visual backward masking has been used to understand the temporal dynamics of subliminal vs. conscious perception. When a brief target stimulus is followed by a masking stimulus after a short interval of <100 ms, performance on the target is impaired when the target and mask are in close spatial proximity.

Autologous hematopoietic stem cell transplantation in neuromyelitis optica: a registry study of the EBMT Autoimmune Diseases Working Party.

Background: Neuromyelitis optica (NMO) is an inflammatory autoimmune disorder of the central nervous system, hallmarked by pathogenic anti-aquaporin 4 antibodies. NMO prognosis is worse compared with multiple sclerosis.

Objective: The European Group for Blood and Marrow Transplantation (EBMT) Autoimmune Diseases Working Party (ADWP) conducted a retrospective survey to analyze disease outcome following autologous stem cell transplantation (ASCT).

Autologous haematopoietic stem cell transplantation for aggressive multiple sclerosis: the Swedish experience.

Background: Autologous haematopoietic stem cell transplantation (HSCT) is a viable option for treatment of aggressive multiple sclerosis (MS). No randomised controlled trial has been performed, and thus, experiences from systematic and sustained follow-up of treated patients constitute important information about safety and efficacy. In this observational study, we describe the characteristics and outcome of the Swedish patients treated with HSCT for MS.

Laminar firing and membrane dynamics in four visual areas exposed to two objects moving to occlusion.

It is not known how visual cortical neurons react to several moving objects and how their firing to the motion of one object is affected by neurons firing to another moving object. Here we combine imaging of voltage sensitive dye (VSD) signals, reflecting the population membrane potential from ferret visual areas 17, 18, 19, and 21, with laminar recordings of multiunit activity, (MUA), when two bars moved toward each other in the visual field, occluded one another, and continued on in opposite directions. Two zones of peak MUA, mapping the bars' motion, moved toward each other along the area 17/18 border, which in the ferret maps the vertical meridian of the field of view.

Incidence and time trends of brain metastases admissions among breast cancer patients in Sweden.

Background: While treatment for breast cancer has been refined and overall survival has improved, there is concern that the incidence of brain metastases has increased.

Methods: We identified patients in Sweden with incident breast cancer 1998-2006 in the National Cancer Register, and matched these to the National Patient Register to obtain information on hospital admissions for distant metastases. Hazard ratios (HRs) and 95% confidence intervals (CIs) were computed with Cox regression as estimates of relative risk.

The expression of VEGF-A is down regulated in peripheral blood mononuclear cells of patients with secondary progressive multiple sclerosis.

Background: Most patients with relapsing-remitting multiple sclerosis (RRMS) eventually enter a secondary progressive (SPMS) phase, characterized by increasing neurological disability. The mechanisms underlying transition to SPMS are unknown and effective treatments and biomarkers are lacking. Vascular endothelial growth factor-A (VEGF-A) is an angiogenic factor with neuroprotective effects that has been associated with neurodegenerative diseases.
