Polygenic risk score adds to a clinical risk score in the prediction of cardiovascular disease in a clinical setting.

Background And Aims: A cardiovascular disease polygenic risk score (CVD-PRS) can stratify individuals into different categories of cardiovascular risk, but whether the addition of a CVD-PRS to clinical risk scores improves the identification of individuals at increased risk in a real-world clinical setting is unknown.

Methods: The Genetics and the Vascular Health Check Study (GENVASC) was embedded within the UK National Health Service Health Check (NHSHC) programme which invites individuals between 40-74 years of age without known CVD to attend an assessment in a UK general practice where CVD risk factors are measured and a CVD risk score (QRISK2) is calculated. Between 2012-2020, 44,141 individuals (55.

Budget Impact Analysis of Circulating Tumor DNA Testing for Colon Cancer in Commercial Health and Medicare Advantage Plans.

Importance: In a randomized clinical trial, treatment guided by tumor-informed circulating tumor (ct)DNA testing reduced adjuvant chemotherapy use without compromising recurrence-free survival in patients with stage II colon cancer. The potential effects of adopting ctDNA testing into routine patient care is unknown.

Objective: To compare the total cost of patient care scenarios with and without the adoption of ctDNA testing.

The predictive role of symptoms in COVID-19 diagnostic models: A longitudinal insight.

To investigate the symptoms of SARS-CoV-2 infection, their dynamics and their discriminatory power for the disease using longitudinally, prospectively collected information reported at the time of their occurrence. We have analysed data from a large phase 3 clinical UK COVID-19 vaccine trial. The alpha variant was the predominant strain.

Efficient removal of antibiotics from water by highly crosslinked metal-alginate particles: Preparation, isotherms, kinetics, and microbiological assay.

Traces of antibiotics reaching aquatic environment lead to the emergence of antimicrobial resistance (AMR). The efficient removal of antibiotics (ATBs) traces from wastewater is essential to tackle the AMR. In this study, a novel solid-state crosslinking method of alginate (ALG) was developed and applied to specifically remove ATBs from water.

A timeline of surgical lighting - Is automated lighting the future?

High quality surgical lighting is central to successful performance in the operating room and therefore to both patient care and treatment. This article discusses the origins of surgical lighting from the 1800s to today, with a focus on the four main forms. Their uses, advantages, and disadvantages are evaluated in an effort to identify the improvements required to improve today's current state of surgical lighting.

Evaluating the clinical effectiveness of the NHS Health Check programme: a prospective analysis in the Genetics and Vascular Health Check (GENVASC) study.

Objective: The aim of the study was to assess the clinical effectiveness of the national cardiovascular disease (CVD) prevention programme-National Health Service Health Check (NHSHC) in reduction of CVD risk.

Design: Prospective cohort study.

Setting: 147 primary care practices in Leicestershire and Northamptonshire in England, UK.

Respiratory Syncytial Virus Disease Burden in Community-Dwelling and Long-Term Care Facility Older Adults in Europe and the United States: A Prospective Study.

Background: Data on respiratory syncytial virus (RSV) disease burden in adults remain scarce. We assessed the burden of confirmed RSV-acute respiratory infections (cRSV-ARIs) in community-dwelling (CD) adults and those in long-term care facilities (LTCFs).

Methods: In this prospective cohort study covering 2 RSV seasons (October 2019-March 2020 and October 2020-June 2021), RSV-ARIs were identified through active surveillance, in medically stable CD-adults ≥50 years (Europe) or adults ≥65 years in LTCFs (Europe and the United States).

Safety and Efficacy of the NVX-CoV2373 Coronavirus Disease 2019 Vaccine at Completion of the Placebo-Controlled Phase of a Randomized Controlled Trial.

Background: The recombinant protein-based vaccine, NVX-CoV2373, demonstrated 89.7% efficacy against coronavirus disease 2019 (COVID-19) in a phase 3, randomized, observer-blinded, placebo-controlled trial in the United Kingdom. The protocol was amended to include a blinded crossover.

It's Not Always SIAD: Immunotherapy-Triggered Endocrinopathies Enter the Field of Cancer-Related Hyponatremia.

While the syndrome of inadequate antidiuresis (SIAD) is still the most common cause of hyponatremia in cancer patients, the rise in endocrine immune-related adverse events (irAEs) owing to immune checkpoint inhibitors (ICI) considerably shaped the differential diagnosis of electrolyte disorders in cancer patients. We report here 3 cases of different endocrine irAEs, first manifesting with new-onset hyponatremia under ICI therapy for malignant melanoma: one with primary adrenal insufficiency, one with hypophysitis, and one with autoimmune type 1 diabetes. Early diagnosis of endocrine toxicities can save lives but may be challenging and essentially delayed by subtle or nonspecific clinical presentation and a lack of readily available endocrinological laboratory evaluation in the primary care setting.

Common postoperative complications after general anesthesia in oral and maxillofacial surgery.

Aim And Objectives: Anesthesia is Greek word meaning loss of sensation, and involves painful invasive procedure to be performed with little distress and no pain to the patient. Postoperative anesthetic complications are very common and duration of surgery is frequently cited as major risk factor for postoperative complications. The recognition and treatment of these complications are important when providing good quality care.

Evaluation of the Economic Benefit of Earlier Systemic Lupus Erythematosus (SLE) Diagnosis Using a Multivariate Assay Panel (MAP).

Objective: Diagnosis of systemic lupus erythematosus (SLE) made by standard diagnostic laboratory tests (SDLTs) has sensitivity and specificity of 83% and 76%, respectively. A multivariate assay panel (MAP) combining complement C4d activation products on erythrocytes and B cells with SDLTs yields a sensitivity and specificity of 80% and 86%, respectively, presumably enabling earlier SLE diagnosis at lower severity, with associated lower health care costs compared with SDLT diagnoses. We compared the payer budget impact of diagnosing SLE using MAP (incremental cost of $108) versus SDLTs.

Frontline Science: Coincidental null mutation of Csf2rα in a colony of PI3Kγ-/- mice causes alveolar macrophage deficiency and fatal respiratory viral infection.

PI3Ks have been identified as key signaling proteins involved in many basic biologic processes in health and disease. Transgenic animals have been essential tools to study the underlying molecular mechanisms in this context and therefore, have been widely used to elucidate the role of these factors in many different settings. More specifically, PI3Kγ, a subunit highly expressed in the hematopoietic system, has been implicated to play an important role in many inflammatory diseases as well as cancer.

PI3Kγ Is Critical for Dendritic Cell-Mediated CD8+ T Cell Priming and Viral Clearance during Influenza Virus Infection.

Phosphoinositide-3-kinases have been shown to be involved in influenza virus pathogenesis. They are targeted directly by virus proteins and are essential for efficient viral replication in infected lung epithelial cells. However, to date the role of PI3K signaling in influenza infection in vivo has not been thoroughly addressed.

Comparing Methods to Denote Treatment Outcome in Clinical Research and Benchmarking Mental Health Care.

Unlabelled: Approaches based on continuous indicators (the size of the pre-to-post-test change; effect size or ΔT) and on categorical indicators (Percentage Improvement and the Jacobson-Truax approach to Clinical Significance) are evaluated to determine which has the best methodological and statistical characteristics, and optimal performance, in comparing outcomes of treatment providers. Performance is compared in two datasets from providers using the Brief Symptom Inventory or the Outcome Questionnaire. Concordance of methods and their suitability to rank providers is assessed.

Alveolar macrophages are essential for protection from respiratory failure and associated morbidity following influenza virus infection.

Alveolar macrophages (AM) are critical for defense against bacterial and fungal infections. However, a definitive role of AM in viral infections remains unclear. We here report that AM play a key role in survival to influenza and vaccinia virus infection by maintaining lung function and thereby protecting from asphyxiation.

Ordered self-assembly mechanism of a spherical oncoprotein oligomer triggered by zinc removal and stabilized by an intrinsically disordered domain.

Background: Self-assembly is a common theme in proteins of unrelated sequences or functions. The human papillomavirus E7 oncoprotein is an extended dimer with an intrinsically disordered domain, that can form large spherical oligomers. These are the major species in the cytosol of HPV transformed and cancerous cells.

Clinical follow-up and histopathology of the temporal bones in Nathalie syndrome.

The Nathalie syndrome (OMIM 255990) comprises a combination of features that do not resemble any other known syndrome and is as such an independent, rare entity. It is characterized by sensorineural hearing impairment, juvenile cataract, spinal muscular atrophy, skeletal abnormalities, retardation of growth, underdeveloped secondary gender characteristics and cardiomyopathy. Worldwide, only one family with this syndrome is known.

Audioprofile-directed successful mutation analysis in a DFNA2/KCNQ4 (p.Leu274His) family.

Objectives: We undertook to show that in a family with nonsyndromic autosomal dominant sensorineural hearing loss, genetic analysis can be successful when there is a match with a specific DFNA audioprofile. We also provide an update of relevant DFNA2/KCNQ4 audioprofiles and report the results of automatic audioprofile analysis using the Internet program AudioGene.

Methods: Audiometric data and blood samples were obtained from the family W08-0384.

Progressive sensorineural hearing loss and normal vestibular function in a Dutch DFNB7/11 family with a novel mutation in TMC1.

In a Dutch family with autosomal recessive hearing loss, genome-wide single-nucleotide polymorphism analysis mapped the genetic defect to the DFNB7/11 locus. A novel homozygous A-to-G change in the TMC1 gene was detected near the splice donor site of intron 19 (c.1763+3A→G) segregating with the hearing loss in this family.

E6*, the 50 amino acid product of the most abundant spliced transcript of the e6 oncoprotein in high-risk human papillomavirus, is a promiscuous folder and binder.

High-risk human papillomavirus E6 participates in tumorigenic progression, mainly by its ability to promote p53 degradation. HPV transcripts show a complex splicing pattern, where E6* is the most abundant transcript in high-risk HPV types, comprising the first 50 amino acids of E6. No structural or biochemical information of this polypeptide, which contains half of the first zinc binding motif of E6, is available, due to the difficulty to acquire a compact monomeric fold in such a small polypeptide.

Aminoacylase 1 deficiency associated with autistic behavior.

Aminoacylase 1 (ACY1) deficiency is a recently described inborn error of metabolism. Most of the patients reported so far have presented with rather heterogeneous neurologic symptoms. At this moment, it is not clear whether ACY1 deficiency represents a true metabolic disease with a causal relationship between the enzyme defect and the clinical phenotype or merely a biochemical abnormality.

Deletions and point mutations of LRRC50 cause primary ciliary dyskinesia due to dynein arm defects.

Genetic defects affecting motility of cilia and flagella cause chronic destructive airway disease, randomization of left-right body asymmetry, and, frequently, male infertility in primary ciliary dyskinesia (PCD). The most frequent defects involve outer and inner dynein arms (ODAs and IDAs) that are large multiprotein complexes responsible for cilia-beat generation and regulation, respectively. Here, we demonstrate that large genomic deletions, as well as point mutations involving LRRC50, are responsible for a distinct PCD variant that is characterized by a combined defect involving assembly of the ODAs and IDAs.
