Changes in Plasma Levels of Prestin and Otolin-1 in Dental Students.

Introduction: Dentists and dental professionals report a high prevalence of noise-induced hearing loss (NIHL) and related symptoms. Chronic exposure to high-frequency dental instrument sounds, which can damage the outer hair cells (OHCs) of the cochlea, is strongly linked to their NIHL. Similarly, dental students in teaching clinics often report symptoms associated with NIHL.

Leveraging Natural Language Processing and Machine Learning Methods for Adverse Drug Event Detection in Electronic Health/Medical Records: A Scoping Review.

Background: Natural language processing (NLP) and machine learning (ML) techniques may help harness unstructured free-text electronic health record (EHR) data to detect adverse drug events (ADEs) and thus improve pharmacovigilance. However, evidence of their real-world effectiveness remains unclear.

Objective: To summarise the evidence on the effectiveness of NLP/ML in detecting ADEs from unstructured EHR data and ultimately improve pharmacovigilance in comparison to other data sources.

Predicting purification process fit of monoclonal antibodies using machine learning.

In early-stage development of therapeutic monoclonal antibodies, assessment of the viability and ease of their purification typically requires extensive experimentation. However, the work required for upstream protein expression and downstream purification development often conflicts with timeline pressures and material constraints, limiting the number of molecules and process conditions that can reasonably be assessed. Recently, high-throughput batch-binding screen data along with improved molecular descriptors have enabled development of robust quantitative structure-property relationship (QSPR) models that predict monoclonal antibody chromatographic binding behavior from the amino acid sequence.

NCHD handover in the acute mental health setting: a quality improvement initiative implementing an electronic handover tool.

Background: Cork University Hospital, Ireland's largest teaching hospital, faced challenges in maintaining consistent handover processes in its Acute Mental Health Unit (AMHU). Prior to 2019, handovers relied on informal methods, risking information loss and compromising patient care. This quality improvement (QI) initiative aimed to standardise handover practices using an electronic tool integrated with the ISBAR communication protocol.

DPPX antibody-mediated disease mimicking Wernicke's encephalopathy.

Anti-dipeptidyl-peptidase-like protein 6 antibody-mediated disease is a rare autoimmune encephalitis typically presenting with diarrhoea and/or weight loss, central nervous system hyperexcitability and cognitive dysfunction. We present a case of a young woman with 10 days of diplopia and unsteadiness in the context of dysthymia and significant weight loss over 2 months. Initial examination demonstrated mixed dysconjugate nystagmus and ataxic gait.

Converting multiple hydrophobic aromatic plastic monomers into a single water-soluble substrate to increase bioavailability for the synthesis of polyhydroxyalkanoates by bacteria using batch, fed batch and continuous cultivation.

We demonstrate the proof of concept of increasing the bioavailability of carbon substrates, derived from plastic waste, for their conversion to the biodegradable polymer polyhydroxyalkanoate [PHA] by bacteria and test various approaches to PHA accumulation through batch, fed batch and continuous culture. Styrene, ethylbenzene, and toluene are produced from the pyrolysis of mixed plastic waste (Kaminsky, 2021; Miandad et al., 2017), but they are volatile and poorly soluble in water making them difficult to work with in aqueous fermentation systems.

Primary arthrodesis versus open reduction internal fixation for acute Lisfranc injuries: a systematic review and meta-analysis.

Introduction: The presence of a Lisfranc injury alone is considered a surgical indication in most patients. Indications for primary arthrodesis (PA) versus open reduction internal fixation (ORIF), however, is a topic of debate among surgeons. Conflicting data exists as to which treatment modality leads to improved patient-reported outcome measures (PROMs), reoperations, and complications.

Automated Evaluation of Antibiotic Prescribing Guideline Concordance in Pediatric Sinusitis Clinical Notes.

Background: Ensuring antibiotics are prescribed only when necessary is crucial for maintaining their effectiveness and is a key focus of public health initiatives worldwide. In cases of sinusitis, among the most common reasons for antibiotic prescriptions in children, healthcare providers must distinguish between bacterial and viral causes based on clinical signs and symptoms. However, due to the overlap between symptoms of acute sinusitis and viral upper respiratory infections, antibiotics are often over-prescribed.

Metformin for the Prevention of Antipsychotic-Induced Weight Gain: Guideline Development and Consensus Validation.

Background: Overweight and obesity are highly prevalent in people with severe mental illness (SMI). Antipsychotic-induced weight gain (AIWG) is one of the most commonly reported and distressing side effects of treatment and people living with SMI place a high value on the avoidance of this side effect. Metformin is the most effective pharmacological intervention studied for the prevention of AIWG yet clear guidelines are lacking and evidence has not translated into practice.

The impact of the COVID-19 pandemic on first-episode psychosis presentations in two early intervention in psychosis services.

Objectives: To assess the impact of the COVID-19 pandemic on first-episode psychosis (FEP) presentations across two Early Intervention in Psychosis (EIP) services in Ireland, by comparing pre-pandemic and post-pandemic cohorts.

Methods: A cross-sectional observational design with retrospective medical record review was employed. The study population comprised 187 FEP patients (77 in pre-pandemic and 110 in post-pandemic cohort).

Flexible fixation versus open reduction internal fixation and primary arthrodesis for ligamentous Lisfranc injuries: A systematic review and meta-analysis.

Introduction: Flexible fixation (FF) has allowed treatment of isolated ligamentous Lisfranc injuries while preserving joint motion. We hypothesize that patient-reported outcome measures (PROMs), complications, and return-to-activity rates will be similar between patients undergoing FF versus those undergoing open reduction internal fixation (ORIF) or primary arthrodesis (PA).

Methods: Databases included PubMed, OVID Medline, Embase, SCOPUS, Cochrane Central Register of Clinical Trials, and clinicaltrials.

Dextran-Encapsulated Nanoparticles and Super-Nanoparticle Assemblies: Preparation from Quantum Dots, Fluorescent Polymers, and Magnetic Nanoparticles for Application to Cellular Immunolabeling.

Nanoparticles (NPs) continue to be developed as labels for bioanalysis and imaging due to their small size and, in many cases, emergent properties such as photoluminescence (PL) and superparamagnetism. Some applications stand to benefit from amplification of the advantageous properties of a NP, but this amplification is not a simple matter of scaling for size-dependent properties. One promising approach to amplification is, therefore, to assemble many copies of a NP into a larger but still nanoscale and colloidal entity.

In vivo models of subclonal oncogenesis and dependency in hematopoietic malignancy.

Cancer evolution is a multifaceted process leading to dysregulation of cellular expansion and differentiation through somatic mutations and epigenetic dysfunction. Clonal expansion and evolution is driven by cell-intrinsic and -extrinsic selective pressures, which can be captured with increasing resolution by single-cell and bulk DNA sequencing. Despite the extensive genomic alterations revealed in profiling studies, there remain limited experimental systems to model and perturb evolutionary processes.

Integrin α6β4 Upregulates PTPRZ1 Through UCHL1-Mediated Hif-1α Nuclear Accumulation to Promote Triple-Negative Breast Cancer Cell Invasive Properties.

Integrin α6β4 drives triple-negative breast cancer (TNBC) aggressiveness through the transcriptional regulation of key genes. Here, we investigated how integrin α6β4 regulates protein tyrosine phosphatase receptor type Z1 (PTPRZ1). Using stable re-expression of integrin β4 (ITGB4) in cells naturally devoid of integrin α6β4 or knockdown or knockout (KO) of ITGB4, we found that integrin α6β4 regulates PTPRZ1 expression.

A Deficiency in Glutamine-Fructose-6-Phosphate Transaminase 1 (Gfpt1) in Skeletal Muscle Results in Reduced Glycosylation of the Delta Subunit of the Nicotinic Acetylcholine Receptor (AChRδ).

The neuromuscular junction (NMJ) is the site where the motor neuron innervates skeletal muscle, enabling muscular contraction. Congenital myasthenic syndromes (CMS) arise when mutations in any of the approximately 35 known causative genes cause impaired neuromuscular transmission at the NMJ, resulting in fatigable muscle weakness. A subset of five of these CMS-causative genes are associated with protein glycosylation.

Early, Individualized Recommendations for Hospitalized Patients With Acute Kidney Injury: A Randomized Clinical Trial.

Importance: Acute kidney injury (AKI) is a common complication during hospitalization and is associated with adverse outcomes.

Objective: To evaluate whether diagnostic and therapeutic recommendations sent by a kidney action team through the electronic health record improve outcomes among patients hospitalized with AKI compared with usual care.

Design, Setting, And Participants: Randomized clinical trial conducted at 7 hospitals in 2 health systems: in New Haven, Bridgeport, New London, and Waterbury, Connecticut, and Westerly, Rhode Island; and in Baltimore, Maryland.

Tricky Ts play possum to propagate autoimmune disease.

Patients with autoimmune disease have exhausted antigen-specific T cells that remain capable of B cell support.

Von Willebrand Factor Activity Association With Outcomes After Transcatheter Edge-to-Edge Mitral Valve Repair.

Background: Residual mitral regurgitation (MR) is associated with worse outcomes after transcatheter edge-to-edge mitral valve repair (TEER). Shear stress induced by MR leads to altered von Willebrand factor activity (vWF:Act) and increased closure time with adenosine diphosphate (CT-ADP).

Objectives: The purpose of this study was to investigate the use of CT-ADP to monitor MR during TEER and the association between the vWF, residual MR, and clinical events post-TEER.

Sensitivity of the familial high-risk approach for the prediction of future psychosis: a total population study.

Children who have a parent with a psychotic disorder present an increased risk of developing psychosis. It is unclear to date, however, what proportion of all psychosis cases in the population are captured by a familial high-risk for psychosis (FHR-P) approach. This is essential information for prevention research and health service planning, as it tells us the total proportion of psychosis cases that this high-risk approach would prevent if an effective intervention were developed.
