What is the clinical utility of acoustic and vibrational analyses in uncemented total hip arthroplasty?

Background: Despite recent developments in THA, a more objective method is needed to assist orthopedic surgeons in identifying the insertion endpoint of the broaching procedure. Therefore, this systematic review evaluated the in-vivo efficacy of various acoustic and vibration analyses in detecting proper implant seating, identifying intraoperative complications, and quantifying the accuracy of predictive modeling using acoustics.

Methods: Four electronic databases were searched on July 23rd, 2023, to retrieve articles evaluating the use of acoustic analysis during THA.

Abbreviated Duke Activity Status Index for Risk Stratification in Heart Failure.

The Duke activity status index (DASI), a self-administered 12-item questionnaire has been used to estimate functional capacity and recently demonstrated prognostic information. We aimed to develop an abbreviated version for clinical applications. Leveraging the Cleveland Clinic GeneBank Study, we developed an abbreviated DASI questionnaire (aDASI) with the machine learning XGBoost algorithm, with the goal of maintaining the accuracy and reliability of the original DASI.

Cell-Penetrating Peptide Induced Superstructures Triggering Highly Efficient Antibacterial Activity.

To endow non-antibacterial molecules with highly efficient bactericide activity is an important but challenging issue. Herein, a kind of cell-penetrating peptide octa-arginine (R8) is found to be effective in activating antibacterial ability when assembling with anionic surfactant sodium dodecyl sulfate (SDS), while individual R8 or SDS shows poor or no antibacterial ability. By combined electrostatic, hydrogen bond, and hydrophobic interactions, R8 and SDS associate into wormlike micelle and lamellar structure by forming supramolecular self-assembling units, depending on their charge ratio (CR).

Skin sensitisation elicitation: Evaluation of the general threshold and considerations for use.

Background: Allergic contact dermatitis (ACD) is an immune response to chemical haptens, involving induction and elicitation phases. Quantitative risk assessment (QRA) reviewing the skin sensitisation potential for all ingredients and using chemical-specific induction thresholds for skin allergens remains the current best approach for the safety evaluation of consumer products. However, elicitation thresholds have utility in secondary protection for pre-sensitised consumers.

Cardiac structural, functional and energetic assessments during and after pregnancy in women with gestational diabetes mellitus, preeclampsia and healthy pregnancy.

Background: GDM and preeclampsia are common complications of pregnancy, for which overweight/obesity is a common risk factor. Both conditions are associated with a two-to-four-fold increase in future incident heart failure, which may be linked to early maladaptive myocardial changes.

Objectives: To determine maternal myocardial structural, functional, and energetic responses to pregnancies complicated by gestational diabetes mellitus (GDM) or preeclampsia compared to healthy pregnancies (HP) at third-trimester of pregnancy and twelve-months postpartum.

Acoustic Droplet Vaporization Efficiency and Oxygen Scavenging in Whole Blood.

Objective: Acoustic droplet vaporization (ADV) is the liquid-to-gas phase transition of perfluorocarbon (PFC) droplets to microbubbles upon ultrasound insonation. After ADV, gases dissolved in the surrounding fluid diffuse into microbubbles, enabling oxygen scavenging. Characterization of oxygen scavenging and transition efficiency (TE) in whole blood has so far been limited.

Tumor cell-derived spermidine promotes a protumorigenic immune microenvironment in glioblastoma via CD8+ T cell inhibition.

The glioblastoma (GBM) microenvironment is enriched in immunosuppressive factors that potently interfere with the function of cytotoxic T lymphocytes. Cancer cells can directly affect the immune system, but the mechanisms driving these interactions are not completely clear. Here, we demonstrate that the polyamine metabolite spermidine (SPD) was elevated in the GBM tumor microenvironment.

Health impact and cost-effectiveness of vaccination using potential next-generation influenza vaccines in Thailand: a modelling study.

Introduction: Thailand was one of the first low- and middle-income countries to publicly fund seasonal influenza vaccines, but the lack of predictability in the timing of epidemics and difficulty in predicting the dominant influenza subtypes present a challenge for existing vaccines. Next-generation influenza vaccines (NGIVs) are being developed with the dual aims of broadening the strain coverage and conferring longer-lasting immunity. However, there are no economic evaluations of NGIVs in Thailand.

A RESPONSE to antiIL-5 therapy in comorbid patients with chronic rhinosinusitis with nasal polyps and severe asthma: Study protocol.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) and severe asthma (SA) are 2 frequently coexisting conditions that are, in most cases, associated with eosinophilic inflammation. The concurrence of both diseases has a negative synergistic impact on disease severity and patients' health-related quality of life. Thus, a holistic, collaborative management of these patients is a critical unmet need.

Light-assisted functionalization of aryl radicals towards metal-free cross-coupling.

The many synthetic possibilities that arise when using radical intermediates, in place of their polar counterparts, make contemporary radical chemistry research an exhilarating field. The introduction of photocatalysis has helped tame aryl radicals, leading to a resurgence of interest in their chemistry, and an expansion of viable coupling partners and attainable transformations. These methods are more selective and safer than classical approaches, and they utilize new radical precursors.

Ultrafast Evolution of Bacterial Antimicrobial Resistance by Picoliter-Scale Centrifugal Microfluidics.

Experimental evolution is a powerful approach for scrutinizing and dissecting the development of antimicrobial resistance; nevertheless, it typically demands an extended duration to detect evolutionary changes. Here, a centrifugal microfluidics system is designed to accelerate the process. Through a simple step of on-chip centrifugation, a highly condensed bacterial matrix of ∼10 cells/mL at the enrichment tip of the chip channel is derived, enabling bacteria encapsulated to survive in antimicrobial concentrations several times higher than the minimum inhibitory concentration (MIC) and rapidly develop resistance in the first 10 h.

The cumulative impact of type 2 diabetes and obstructive sleep apnoea on cardiovascular, liver, diabetes-related and cancer outcomes.

Aim: A bidirectional relationship exists between obstructive sleep apnoea (OSA) and type 2 diabetes (T2D). We aimed to examine the cumulative impact of having both OSA and T2D on patient outcomes, relative to having either condition alone.

Materials And Methods: Using TriNetX, a global federated research network (n = 128 million), we undertook two retrospective cohort studies, using time-to-event analysis.

Scalp condition improvement with botanical extracts possessing chemical and physical antioxidant activity.

Objective: Oxidative stress is implicated in scalp and hair health manifesting in several ways, including skin barrier, hair retention, healthy hair appearance and scalp sensation. We previously linked markers of oxidative damage to dandruff and skin barrier impairment and have linked key anti-dandruff technologies to the resolution of these issues. Here we expand the therapeutic space demonstrating many botanical extracts offer protective benefits against ROS stress via both chemical and biological antioxidant mechanisms.

Sensing the Changes in Stratum Corneum Using Fourier Transform Infrared Microspectroscopy and Hyperspectral Data Processing.

The stratum corneum (SC) forms the outermost layer of the skin, playing a critical role in preventing water loss and protecting against external biological and chemical threats. Approximately 90% of the SC consists of large, flat corneocytes, yet its barrier function primarily relies on the intercellular lipid matrix that surrounds these cells. Traditional methods for characterizing these lipids, such as Fourier transform infrared spectroscopy (FTIR), typically involve macroscopic analysis using attenuated total reflection (ATR) techniques.

Patient Experience and Expectations in Oral Health Care: A Nation-Wide Survey.

Aim: This research was conducted to understand patients' dental visit habits and behaviours and to identify factors contributing to a positive patient experience at the dental office in Canada METHODS: An online survey was distributed to members of a market research panel in the United States. Qualifying panellists were 25 years of age or older who visited a dentist in the past year. Survey questions were related to frequency of dental visits, patient satisfaction with the dental office, importance of dental office attributes and dental product recommendation expectations.

Antibiofilm approaches as a new paradigm for treating infections.

The lack of effective antibiotics for drug-resistant infections has led the World Health Organization to declare antibiotic resistance a global priority. Most bacterial infections are caused by microbes growing in structured communities called biofilms. Bacteria growing in biofilms are less susceptible to antibiotics than their planktonic counterparts.

Updated assessment of the genotoxic potential of titanium dioxide based on reviews of in vitro comet, mode of action and cellular uptake studies, and recent publications.

In 2021 the European Food Safety Authority (EFSA) concluded that "A concern for genotoxicity of TiO2 particles that may be present in E 171 could therefore not be ruled out.". A detailed review of the genotoxicity of titanium dioxide (TiO) was subsequently published by Kirkland et al.

Search for the Exclusive W Boson Hadronic Decays W^{±}→π^{±}γ, W^{±}→K^{±}γ and W^{±}→ρ^{±}γ with the ATLAS Detector.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.
