Physician-dentist dual referral model concept for coordinated bone anabolic therapy.

Background: Bone anabolic drugs used for the pharmacologic treatment of osteoporosis have the potential to enhance alveolar bone regeneration to improve implant success. There are no US Food and Drug Administration-approved drugs indicated to improve oral bone density around teeth or implants.

Methods: The authors summarized expert opinions on a novel coordinated treatment approach leveraging the effects of systemic bone anabolic drugs to enhance dental implant therapy in patients with osteoporosis and a dual referral model for physicians and dentists to address the clinical needs of patients with osteoporosis from a comprehensive perspective of oral-systemic health.

Healing sequelae following tooth extraction and dental implant placement in an aged, ovariectomy model.

At present, a lack of consensus exists regarding the clinical impact of osteoporosis on alveolar bone metabolism during implant osseointegration. While limited preclinical and clinical evidence demonstrates a negative influence of osteoporosis on dental extraction socket healing, no preclinical studies offer data on the results of implant placement in 6-mo-old, ovariectomized (OVX) Sprague-Dawley rats. This study aimed to investigate the outcomes of dental tooth extraction socket healing and implant placement in a rodent model of osteoporosis following daily vehicle (VEH) or abaloparatide (ABL) administration.

Landscape of Differentiation Potentials as a "Hallmark" in Oral-derived MSCs.

Background: Mesenchymal stem cells (MSCs) offer clinical promise for use in cell therapy approaches for regenerative medicine. A therapeutic challenge is that MSCs from different tissues are phenotypically and functionally distinct. Therefore, this study aims to molecularly characterize oral-derived MSCs by defining one of the three hallmarks of MSCs, differentiation potential, to discern their true molecular identities.

Salivary and serum inflammatory biomarkers during periodontitis progression and after treatment.

Aim: To identify serum- and salivary-derived inflammatory biomarkers of periodontitis progression and determine their response to non-surgical treatment.

Materials And Methods: Periodontally healthy (H; n = 113) and periodontitis patients (P; n = 302) were monitored bi-monthly for 1 year without therapy. Periodontitis patients were re-examined 6 months after non-surgical periodontal therapy (NSPT).

The human pupil and face encode sound affect and provide objective signatures of tinnitus and auditory hypersensitivity disorders.

Sound is jointly processed along acoustic and emotional dimensions. These dimensions can become distorted and entangled in persons with sensory disorders, producing a spectrum of loudness hypersensitivity, phantom percepts, and - in some cases - debilitating sound aversion. Here, we looked for objective signatures of disordered hearing (DH) in the human face.

Quantification of the Culture Stability of Stem Cell Fractions from Oral-Derived, Human Mesenchymal Stem Cell Preparations: A Significant Step toward the Clinical Translation of Cell Therapies.

A continuing limitation and major challenge in the development and utilization of predictable stem cell therapies (SCTs) is the determination of the optimal dosages of stem cells. Herein, we report the quantification of stem cell fractions (SCF) of human mesenchymal stem cell (MSC) preparations derived from oral tissues. A novel computational methodology, kinetic stem cell (KSC) counting, was used to quantify the SCF and specific cell culture kinetics of stem cells in oral alveolar bone-derived MSC (aBMSCs) from eight patients.

A dataset for benchmarking Neotropical anuran calls identification in passive acoustic monitoring.

Global change is predicted to induce shifts in anuran acoustic behavior, which can be studied through passive acoustic monitoring (PAM). Understanding changes in calling behavior requires automatic identification of anuran species, which is challenging due to the particular characteristics of neotropical soundscapes. In this paper, we introduce a large-scale multi-species dataset of anuran amphibians calls recorded by PAM, that comprises 27 hours of expert annotations for 42 different species from two Brazilian biomes.

Inhibition of Mertk Signaling Enhances Bone Healing after Tooth Extraction.

Regeneration of alveolar bone is an essential step in restoring healthy function following tooth extraction. Growth of new bone in the healing extraction socket can be variable and often unpredictable when systemic comorbidities are present, leading to the need for additional therapeutic targets to accelerate the regenerative process. One such target is the TAM family (Tyro3, Axl, Mertk) of receptor tyrosine kinases.

Single-center survey of incidental imaging findings on computed tomography in patients with psoriasis on biologic therapy.

Psoriasis is an immune-mediated chronic inflammatory disease that predominantly affects the skin and joints. Systemic therapies are required for patients with moderate-to-severe psoriasis, and biologics can provide significant symptomatic improvement. Computed tomography (CT) analysis is recommended before and after biologic therapy to exclude the possibility of comorbid infections and malignancies; incidental findings are often detected in asymptomatic patients.

Four-year drug survival of apremilast in patients with psoriasis.

This real-world study at a single academic center retrospectively examined the drug survival of apremilast for patients with psoriasis. Retrospective information was extracted from the medical records of patients with psoriasis treated with apremilast at the Department of Dermatology, Jichi Medical University Hospital, between March 1, 2017, and June 31, 2021. In total, 281 patients were included in this study.

Effect of laser-assisted reconstructive surgical therapy of peri-implantitis on protein biomarkers and bacterial load.

Objectives: This randomized clinical trial assessed changes in protein biomarker levels and bacterial profiles after surgical reconstructive therapy of peri-implantitis and investigated whether the adjunctive use of Er:YAG laser impacts protein biomarker and microbial outcomes.

Materials And Methods: Twenty-four patients received surgical reconstructive therapy for peri-implantitis with guided bone regeneration following mechanical debridement with (test) or without (control) the adjunctive irradiation of Er:YAG laser. Bacterial and peri-implant crevicular fluid (PICF) samples were collected over 6 months and analyzed with bacterial qPCR and luminex multiplex assays.

BMP Gene-Immobilization to Dental Implants Enhances Bone Regeneration.

For individuals who have experienced tooth loss, dental implants are an important treatment option for oral reconstruction. For these patients, alveolar bone augmentation and acceleration of osseointegration optimize implant stability. Traditional oral surgery often requires invasive procedures, which can result in prolonged treatment time and associated morbidity.

Proactive versus Rank-Down Topical Corticosteroid Therapy for Maintenance of Remission in Pediatric Atopic Dermatitis: A Randomized, Open-Label, Active-Controlled, Parallel-Group Study (Anticipate Study).

Topical corticosteroids are used as first-line treatment for atopic dermatitis (AD). Regarding the maintenance of remission achieved by topical corticosteroids, no previous studies have compared proactive therapy with rank-down therapy. We compared their efficacy and safety in Japanese children with moderate to severe AD.

Automatic identification of tinnitus malingering based on overt and covert behavioral responses during psychoacoustic testing.

Tinnitus, or ringing in the ears, is a prevalent condition that imposes a substantial health and financial burden on the patient and to society. The diagnosis of tinnitus, like pain, relies on patient self-report, which can complicate the distinction between actual and fraudulent claims. Here, we combined tablet-based self-directed hearing assessments with neural network classifiers to automatically differentiate participants with tinnitus (N = 24) from a malingering cohort, who were instructed to feign an imagined tinnitus percept (N = 28).

Recombinant human platelet-derived growth factor improves root coverage of a collagen matrix for multiple adjacent gingival recessions: A triple-blinded, randomized, placebo-controlled trial.

Aim: To evaluate the efficacy of recombinant human platelet-derived growth factor (rhPDGF)-BB combined with a cross-linked collagen matrix (CCM) for the treatment of multiple adjacent gingival recession type 1 defects (MAGRs) in combination with the coronally advanced flap (CAF).

Materials And Methods: Thirty patients were enrolled in this triple-blind, randomized, placebo-controlled trial and treated with either CAF + CCM + rhPDGF, or CAF + CCM + saline. The primary outcome was mean root coverage (mRC) at 6 months.

Changes in salivary biomarkers associated with periodontitis and diabetic neuropathy in individuals with type 1 diabetes.

The objective of this pilot clinical study was to identify salivary biomarkers that are associated with periodontal disease and measures of diabetic autonomic dysfunction. Saliva samples from 32 participants were obtained from 3 groups: healthy (H), type 1 diabetes mellitus (DM), and type 1 diabetes mellitus with neuropathy (DMN). Based on the periodontal examination, individuals' mean Periodontal Screening and Recording scores were categorized into two groups (periodontally healthy and gingivitis), and correlated to specific salivary inflammatory biomarkers assessed by a customized protein array and enzyme assay.

Multicompartmental Scaffolds for Coordinated Periodontal Tissue Engineering.

Successful periodontal repair and regeneration requires the coordinated responses from soft and hard tissues as well as the soft tissue-to-bone interfaces. Inspired by the hierarchical structure of native periodontal tissues, tissue engineering technology provides unique opportunities to coordinate multiple cell types into scaffolds that mimic the natural periodontal structure in vitro. In this study, we designed and fabricated highly ordered multicompartmental scaffolds by melt electrowriting, an advanced 3-dimensional (3D) printing technique.

Pro-inflammatory profiles in cardiovascular disease patients with peri-implantitis.

Background: To investigate the pro-inflammatory cytokine profiles in patients with or without cardiovascular disease (CVD) and with or without peri-implantitis.

Methods: Serum, peri-implant crevicular fluid (PICF), and gingival crevicular fluid (GCF) were collected from patients with (n = 82) or without CVD (n = 46) at the most severe peri-implantitis site including sites with periodontitis. A panel of proinflammatory molecules including high-sensitivity C-reactive protein (hsCRP), fibrinogen, interleukin-1 beta (IL-1β), IL-6, plasma tumor necrosis factor-alpha (TNF-α), matrix metallo-proteinase-8 (MMP-8), osteoprotegerin (OPG), vascular endothelial growth factor (VEGF), IL-17, IL-8, tissue inhibitor of metalloproteinase-2 (TIMP-2), myeloperoxidase (MPO), and prostaglandin E (PGE ) were analyzed using human custom Quantibody arrays.

STAT3 Activation in Psoriasis and Cancers.

Activation of signal transducer and activator of transcription (STAT)3 has been reported in many cancers. It is also well known that STAT3 is activated in skin lesions of psoriasis, a chronic skin disease. In this study, to ascertain whether patients with psoriasis have a predisposition to STAT3 activation, we examined phosphorylated STAT3 in cancer cells of psoriasis patients via immunohistochemistry.

Machine learning-assisted immune profiling stratifies peri-implantitis patients with unique microbial colonization and clinical outcomes.

The endemic of peri-implantitis affects over 25% of dental implants. Current treatment depends on empirical patient and site-based stratifications and lacks a consistent risk grading system. We investigated a unique cohort of peri-implantitis patients undergoing regenerative therapy with comprehensive clinical, immune, and microbial profiling.
