Marine-Derived Polysaccharide Hydrogels as Delivery Platforms for Natural Bioactive Compounds.

Marine polysaccharide hydrogels have emerged as an innovative platform for regulating the in vivo release of natural bioactive compounds for medical purposes. These hydrogels, which have exceptional biocompatibility, biodegradability, and high water absorption capacity, create effective matrices for encapsulating different bioactive molecules. In addition, by modifying the physical and chemical properties of marine hydrogels, including cross-linking density, swelling behavior, and response to external stimuli like pH, temperature, or ionic strength, the release profile of encapsulated bioactive compounds is strictly regulated, thus maximizing therapeutic efficacy and minimizing side effects.

The Development of a Calculator for Objectively Evaluating Supervisory Behaviors in Practice.

Supervision has been a popular topic of study by behavior analysts for the last decade. This popularity came about after several hallmark articles were published and key events in our profession enhanced clarity regarding how much impact supervision can have on important variables such as the quality of behavior-analytic service delivery, patient outcomes, staff satisfaction, and level of staff burnout. Despite the increase in the volume of supervision literature, few articles have provided concrete recommendations for how to objectively evaluate supervisory behaviors in practice.

Thermo-Responsive Hydrogel Containing Microfluidic Chitosan Nanoparticles Loaded with Extract for Periodontitis Treatment.

Periodontitis is a chronic inflammatory disease resulting from the dysbiosis of periodontal bacteria and the host's immune response, leading to tissue degradation and sustained inflammation. Traditional treatments, such as mechanical debridement and antimicrobial agents, often fail to fully eradicate pathogenic bacteria, especially in deep periodontal pockets. Consequently, the need for novel therapeutic approaches has increased the interest in bioactive natural extracts, such as that of , known for its anti-inflammatory, antioxidant, and antimicrobial properties.

Stimuli-Responsive Nanocomposite Hydrogels for Oral Diseases.

Oral diseases encompassing conditions such as oral cancer, periodontitis, and endodontic infections pose significant challenges due to the oral cavity's susceptibility to pathogenic bacteria and infectious agents. Saliva, a key component of the oral environment, can compromise drug efficacy during oral disease treatment by diluting drug formulations and reducing drug-site interactions. Thus, it is imperative to develop effective drug delivery methods.

Extracellular Vesicles Derived from Fruit (OFI-EVs) Speed Up the Normal Wound Healing Processes by Modulating Cellular Responses.

Plant-derived extracellular vesicles (EVs) have been recognized as important mediators of intercellular communication able to transfer active biomolecules across the plant and animal kingdoms. EVs have demonstrated an impressive array of biological activities, displaying preventive and therapeutic potential in mitigating various pathological processes. Indeed, the simplicity of delivering exogenous and endogenous bioactive molecules to mammalian cells with their low cytotoxicity makes EVs suitable agents for new therapeutic strategies for a variety of pathologies.

Comparing Clinician Estimates versus a Statistical Tool for Predicting Risk of Death within 45 Days of Admission for Cancer Patients.

Objectives:  While clinical practice guidelines recommend that oncologists discuss goals of care with patients who have advanced cancer, it is estimated that less than 20% of individuals admitted to the hospital with high-risk cancers have end-of-life discussions with their providers. While there has been interest in developing models for mortality prediction to trigger such discussions, few studies have compared how such models compare with clinical judgment to determine a patient's mortality risk.

Methods:  This study is a prospective analysis of 1,069 solid tumor medical oncology hospital admissions ( = 911 unique patients) from February 7 to June 7, 2022, at Memorial Sloan Kettering Cancer Center.

Despite the merits of maintaining regular contact with the published literature, barriers exist to doing so.

Plasma Exosomal microRNA Profile Reveals miRNA 148a-3p Downregulation in the Mucosal-Dominant Variant of Pemphigus Vulgaris.

The mucosal-dominant variant of pemphigus vulgaris (MPV) is an autoimmune disease characterized by oral mucosal blistering and circulating pathogenic IgG antibodies against desmoglein 3 (Dsg3), resulting in life-threatening bullae and erosion formation. Recently, microRNAs (miRNAs) have emerged as promising players in the diagnosis and prognosis of several pathological states. For the first time, we have identified a different expression profile of miRNAs isolated from plasma-derived exosomes (P-EVs) of MPV patients positive for antibodies against Dsg3 (Dsg3-positive) compared to healthy controls.

Polylactic Acid/Poly(vinylpyrrolidone) Co-Electrospun Fibrous Membrane as a Tunable Quercetin Delivery Platform for Diabetic Wounds.

Diabetic wound infections (DWI) represent one of the most costly and disruptive complications in diabetic mellitus. The hyperglycemic state induces a persistent inflammation with immunological and biochemical impairments that promotes delayed wound healing processes and wound infection that often results in extended hospitalization and limb amputations. Currently, the available therapeutic options for the management of DWI are excruciating and expensive.

Physical and Mental Demand During Total Hip Arthroplasty.

This study compared differences in (1) task duration; (2) biometric parameters (ie, caloric energy expenditure, heart rate); and (3) subjective measures of mental as well as physical demand of robotic-assisted total hip arthroplasty (THA) and manual THA. A total of 12 THAs were performed on 6 cadaveric specimens by two surgeons using a wearable technology to track biometric parameters and taking a questionnaire to compare the physical and mental demands. The results of our study suggest that as compared with manual techniques, robotic assistance for THA may reduce mental and physical fatigue.

Secondary objectives assessed the number of encounters and time spent counseling and medications prescribed at each visit.

Analytical Validation and Performance Characteristics of Molecular Serum Biomarkers, miR-371a-3p and miR-372-3p, for Male Germ Cell Tumors, in a Clinical Laboratory Setting.

Detection of serum embryonic miRNAs miR-371a-3p and miR-372-3p has been proposed to aid in diagnosis, prognosis, and management of patients with testicular germ cell tumors (GCTs). This study describes the analytical validation and performance of a laboratory-developed test to detect these miRNA targets by stem loop real-time quantitative RT-PCR (RT-qPCR) in serum from patients with GCTs. The assay was standardized using an exogenous spike-in control of nonhuman miRNA from Caenorhabditis elegans (cel-miR-39-3p) to assess extraction efficiency, and an endogenous housekeeping miRNA, miR-30b-5p, to control for miRNA normalization.

Thermo-Responsive Gel Containing Hydroxytyrosol-Chitosan Nanoparticles (Hyt@tgel) Counteracts the Increase of Osteoarthritis Biomarkers in Human Chondrocytes.

Although osteoarthritis (OA) is a chronic inflammatory degenerative disease affecting millions of people worldwide, the current therapies are limited to palliative care and do not eliminate the necessity of surgical intervention in the most severe cases. Several dietary and nutraceutical factors, such as hydroxytyrosol (Hyt), have demonstrated beneficial effects in the prevention or treatment of OA both in vitro and in animal models. However, the therapeutic application of Hyt is limited due to its poor bioavailability following oral administration.
