Health disparities investigated in a primary care penicillin allergy removal pathway.

Unconfirmed penicillin allergies over time lead to poor health outcomes and increased health-care cost. Health disparities (HD) can create barriers in optimizing penicillin allergy care. The objective was to characterize HDs in our primary care-led amoxicillin challenge (PLAC) delabeling pathway within a universal coverage health care system.

Silencing Multiple Crustacean Hyperglycaemic Hormone-Encoding Genes in the Redclaw Crayfish Induces Faster Molt Rates with Anomalies.

RNA interference (RNAi)-based biotechnology has been previously implemented in decapod crustaceans. Unlike traditional RNAi methodologies that investigate single gene silencing, we employed a multigene silencing approach in decapods based on chimeric double-stranded RNA (dsRNA) molecules coined 'gene blocks'. Two dsRNA constructs, each targeting three genes of the crustacean hyperglycaemic hormone (CHH) superfamily of neuropeptides, were produced: Type II construct targeting Molt-inhibiting hormone 1 (MIH1), MIH-like 1 (MIHL1), and MIHL2 isoforms and Type I construct targeting ion transport peptide (ITP; a putative hybrid of CHH and MIH) and CHH and CHH-like (CHHL) isoforms.

Anatomo-functional changes in neural substrates of cognitive memory in developmental amnesia: Insights from automated and manual Magnetic Resonance Imaging examinations.

Despite bilateral hippocampal damage dating to the perinatal or early childhood period and severely impaired episodic memory, patients with developmental amnesia continue to exhibit well-developed semantic memory across the developmental trajectory. Detailed information on the extent and focality of brain damage in these patients is needed to hypothesize about the neural substrate that supports their remarkable capacity for encoding and retrieval of semantic memory. In particular, we need to assess whether the residual hippocampal tissue is involved in this preservation, or whether the surrounding cortical areas reorganize to rescue aspects of these critical cognitive memory processes after early injury.

Viscosupplementation with High Molecular Weight Hyaluronic Acid for Hip Osteoarthritis: a Systematic Review and Meta-Analysis of Randomised Control Trials of the Efficacy on Pain, Functional Disability, and the Occurrence of Adverse Events.

Purpose Of The Study: Hip osteoarthritis (OA) has a prevalence of around 6.4% and is the second most commonly affected joint. This review aims to assess the clinical outcomes of intra-articular high molecular weight hyaluronic acid (HMWHA) in the management of hip osteoarthritis.

Removing penicillin allergy label in a hospitalized adolescent with a remote penicillin and recent cephalosporin allergy.

β-Lactam antibiotics are widely used with increased utilization in hospitalized patients. Of this population, as high as 10-20% report an allergy to β-lactam antibiotics but <5% are at risk of developing clinically significant immunoglobulin E- or T-lymphocyte-mediated reactions. Most of the time, these reported allergies are present during an illness with no previous inquiry of their validity, which makes investigation and possible removal of this allergy label a challenge.

Are "clean" products safe for children? An analysis of contact allergens in "clean" children's products from a popular retailer.

Background: Considering consumer trends toward the use of "clean" personal care products and increasing recognition of childhood allergic contact dermatitis, we sought to characterize the allergen profile of such children's products.

Methods: Ingredients of baby washes/shampoos, bubble baths, and moisturizers identified using the "Clean Baby" filter on Target®'s online marketplace were analyzed for relevant pediatric contact allergens.

Results: Product compositions declared fragrance in 82% of products, Compositae in 46%, cocamidopropyl betaine in 45%, glucosides in 37%, propylene glycol in 12%, lanolin in 1%, and no allergens in 9%-methylisothiazolinone and formaldehyde were not found.

Quantitative Foot Muscle Magnetic Resonance Imaging Reliably Measures Disease Progression in Children and Adolescents with Charcot-Marie-Tooth Disease Type 1A.

Quantitative muscle fat fraction (FF) responsiveness is lower in younger Charcot-Marie-Tooth disease type 1A (CMT1A) patients with lower baseline calf-level FF. We investigated the practicality, validity, and responsiveness of foot-level FF in this cohort involving 22 CMT1A patients and 14 controls. The mean baseline foot-level FF was 25.

Cognitive outcome and its neural correlates after cardiorespiratory arrest in childhood.

Hypoxia-ischaemia (HI) can result in structural brain abnormalities, which in turn can lead to behavioural deficits in various cognitive and motor domains, in both adult and paediatric populations. Cardiorespiratory arrest (CA) is a major cause of hypoxia-ischaemia in adults, but it is relatively rare in infants and children. While the effects of adult CA on brain and cognition have been widely studied, to date, there are no studies examining the neurodevelopmental outcome of children who suffered CA early in life.

A Case of Refractory Eosinophilic Gastrointestinal Disease Successfully Treated With Dupilumab.

Eosinophilic infiltration of the gastrointestinal (GI) tract beyond the esophagus is a rare condition in adults with limited data on treatment. Current treatments with steroids and diet modifications have shown benefit, but when these treatments fall short, there is little research-driven guidance for further recommendations. We present a case of eosinophilic GI disease with extensive involvement of the GI tract successfully treated with dupilumab after failure of traditional treatment occurred.

Tropical rock lobster (Panulirus ornatus) uses chemoreception via the antennular lateral flagellum to identify conspecific ecdysis.

The tropical rock lobster, Panulirus ornatus, is a commercially important aquaculture species exhibiting complex social interactions in laboratory culture, including cannibalism of moulting conspecifics. Cannibalism of soft-shelled post-moult stage individuals is a major limitation during the juvenile stage of culture. Not limited to P.

An Anatomic Assessment of the Intercavernous Sinuses and Review of the Literature.

 As expanded endoscopic endonasal approaches are gaining popularity, a thorough understanding of the anatomy of the intercavernous sinuses is pertinent to avoid bleeding complications. There have been few studies reporting the presence and dimensions of the anterior intercavernous sinus (AIS), posterior intercavernous sinus (PIS), and inferior intercavernous sinus (IIS). We performed a cadaveric study to better understand these structures.

Predicting opioid use disorder before and after the opioid prescribing peak in the United States: A machine learning tool using electronic healthcare records.

Existing predictive models of opioid use disorder (OUD) may change as the rate of opioid prescribing decreases. Using Veterans Administration's EHR data, we developed machine-learning predictive models of new OUD diagnoses and ranked the importance of patient features based on their ability to predict a new OUD diagnosis in 2000-2012 and 2013-2021. Using patient characteristics, the three separate machine learning techniques were comparable in predicting OUD, achieving an accuracy of >80%.

Anatomo-functional changes in neural substrates of cognitive memory in developmental amnesia: Insights from automated and manual MRI examinations.

Despite bilateral hippocampal damage dating to perinatal or early-childhood period, and severely-impaired episodic memory that unfolds in later childhood, patients with developmental amnesia continue to exhibit well-developed semantic memory across the developmental trajectory. Detailed information on the extent and focality of brain damage in these patients is needed to hypothesize about the neural substrate that supports their remarkable capacity for encoding and retrieval of semantic memory. In particular, we need to assess whether the residual hippocampal tissue is involved in this preservation, or whether the surrounding cortical areas reorganise to rescue aspects of these critical cognitive memory processes after early injury.

A Tale of Two Lobsters-Transcriptomic Analysis Reveals a Potential Gap in the RNA Interference Pathway in the Tropical Rock Lobster .

RNA interference (RNAi) has been widely utilised in many invertebrate models since its discovery, and in a majority of instances presents as a highly efficient and potent gene silencing mechanism. This is emphasized in crustaceans with almost all taxa having the capacity to trigger effective silencing, with a notable exception in the spiny lobsters where repeated attempts at dsRNA induced RNAi have demonstrated extremely ineffective gene knockdown. A comparison of the core RNAi machinery in transcriptomic data from spiny lobsters () and the closely related slipper lobsters ( where silencing is highly effective) revealed that both lobsters possess all proteins involved in the small interfering and microRNA pathways, and that there was little difference at both the sequence and domain architecture level.

Prognostic indicators and outcomes of hospitalised COVID-19 patients with neurological disease: An individual patient data meta-analysis.

An Efficient Pipeline for Biophysical Modeling of Neurons.

Automation of the process of developing biophysical conductance-based neuronal models involves the selection of numerous interacting parameters, making the overall process computationally intensive, complex, and often intractable. A recently reported insight about the possible grouping of currents into distinct biophysical modules associated with specific neurocomputational properties also simplifies the process of automated selection of parameters. The present paper adds a new current module to the previous report to design spike frequency adaptation and bursting characteristics, based on user specifications.

The use of dried blood spot cards to assess serologic responses of individuals vaccinated against measles, hepatitis A, tetanus, influenza and varicella zoster.

Traditional blood sampling by venipuncture is cumbersome and relatively expensive. Dried blood spot (DBS) sampling is desirable because of its ease of sample collection, transportation and storage. It has been used in clinical diagnosis but not been thoroughly studied for the potential use to assess the immune status of individuals following natural infection or preventive vaccination.
