Non-healing extraction socket: a diagnostic challenge for general dental practitioners.

Introduction In the UK, more than 18 million extractions are performed annually. Healing after extraction is often uneventful, but there are rare cases where weeks or months pass and an extraction socket does not heal.Aim The aim of this study is to provide a review of cases in which a non-healing extraction socket is attributed to a serious systemic disease or malignancy, or an adverse consequence of systemic therapy.

The Expanding Dissemination and Distribution Patterns of Diverse CRISPR Plasmids by Addgene.

CRISPR-based technologies have rapidly enabled the democratization of genome editing in academic institutions through distribution by Addgene over the past decade. Recently, several distribution milestones have been reached, with a collection of >15,000 plasmids deposited by >1,000 laboratories spanning ∼40 countries now shipped 300,000 times to ∼5,000 organizations traversing ∼100 countries. Yet, both deposits of and requests for CRISPR plasmids continue to rise for this disruptive technology.

Objectives: The aim of this cross-sectional study was to explore the structural validity and internal consistency reliability of General Anxiety Disorder-7, Patient Health Questionnaire-8, 15 and Jaw Functional Limitation Scale-20 in patients with chronic pain of temporomandibular disorders.

Materials And Methods: Validity and reliability were assessed in 129 patients diagnosed according to the diagnostic criteria for temporomandibular disorders. Structural validity was explored using factor analysis, and internal consistency by calculating Cronbach α.

Interventions that aim to increase social participation through recreation or leisure activity for adults with moderate to severe traumatic brain injury: a scoping review.

Purpose: Social isolation and reduced social participation are common after traumatic brain injury (TBI). Developing interventions that aim to increase social participation through recreation or leisure activities continues to be challenging. This scoping review was conducted to provide an overview of interventions used to increase social participation through in-person recreation or leisure activity for adults with moderate to severe TBI living in the community.

The development and cognitive testing of a patient-reported experience measure for patients with chronic pain of temporomandibular disorders.

Introduction: The importance of the patients' clinical experience has been reinforced several times over the last decade by healthcare organisations and policy makers. Routine gathering of experience data can help in enhancing patient-centred care and provide guidance to quality improvement schemes. Patient-reported experience measures can help to that end.

Patient-Reported Outcome Measures Used in Temporomandibular Disorders: A Review of the Literature.

Aims: To identify the range of patient-reported outcome measures (PROMs) used in TMD studies, summarize the available evidence for their psychometric properties, and provide guidance for the selection of such measures.

Methods: A comprehensive search was conducted to retrieve articles published between 2009 and 2018 containing a patient-reported measure of the effects of TMDs. Three databases were searched: MEDLINE, Embase, and Web of Science.

A Meta-Synthesis of the Experience of Chronic Temporomandibular Disorder Patients Within Health Care Services.

To systematically review the qualitative evidence related to experiences of patients with temporomandibular disorders (TMD) and to explore their journeys within health care services. A systematic search of the following databases was conducted: MEDLINE, Embase, PsycINFO, Web of Science, CINAHL Complete, and the Cochrane database. Thematic synthesis was used to analyze and synthesize the data from qualitative studies that explored the journeys of TMD patients within health care services.

Healthcare priorities in patients with chronic facial pain of temporomandibular disorders.

Objectives: To explore the experiences of patients with temporomandibular disorders (TMDs) with the National Health Service and to discover their healthcare priorities when seeking treatment.

Methods: Semi-structured interviews were used. They were directed using a topic guide covering subjects such as initial visits in primary care, referrals to secondary care, and the effect on symptoms.

Finding Goal Focus With People With Severe Traumatic Brain Injury in a Person-Centered Multi-Component Community Connection Program (M-ComConnect).

Loss of social connections in the community is a common consequence of severe traumatic brain injury (TBI), resulting in reduced well-being and quality of life. M-ComConnect is an individualized multi-component community connection intervention with the key objectives of increasing social activity, developing social relationships, and supporting community participation following severe TBI. As part of the M-ComConnect approach, semi-structured initial interviews were conducted to develop a holistic understanding of each participant and their goal focus for the project.

A proof of concept pilot trial of probiotics in symptomatic oral lichen planus (CABRIO).

Objective: To preliminary evaluate the clinical effects of probiotics in individuals with symptomatic oral lichen planus and the possible mechanisms of action.

Subjects And Methods: A group of 30 individuals with symptomatic oral lichen planus were recruited in a randomised double-blind parallel group controlled (1:1) proof-of-concept pilot trial of probiotic VSL#3 vs placebo. Efficacy outcomes included changes in pain numeric rating scale, oral disease severity score and the chronic oral mucosal disease questionnaire.

A single-cell landscape of high-grade serous ovarian cancer.

Malignant abdominal fluid (ascites) frequently develops in women with advanced high-grade serous ovarian cancer (HGSOC) and is associated with drug resistance and a poor prognosis. To comprehensively characterize the HGSOC ascites ecosystem, we used single-cell RNA sequencing to profile ~11,000 cells from 22 ascites specimens from 11 patients with HGSOC. We found significant inter-patient variability in the composition and functional programs of ascites cells, including immunomodulatory fibroblast sub-populations and dichotomous macrophage populations.

Osteonecrosis and osteomyelitis of the jaw associated with tumour necrosis factor-alpha (TNF-α) inhibitors: a systematic review.

Tumour necrosis factor-α (TNF-α) inhibitors are increasingly being used as immunomodulators to manage inflammatory conditions such as rheumatoid arthritis and Crohn's disease. Reported serious side effects include an increased incidence of lymphoma and greater susceptibility to infections such as tuberculosis. The aim of this systematic review was to find out whether there is an associated risk of medication-related osteonecrosis of the jaw (MRONJ).

Prevalence, predictive factors and clinical course of persistent pain associated with teeth displaying periapical healing following nonsurgical root canal treatment: a prospective study.

Aims: To investigate the prevalence, pain catastrophizing and other predictive factors and clinical course of persistent pain/discomfort associated with teeth displaying periapical healing following nonsurgical root canal treatment (NSRCT).

Methodology: One hundred and ninety-eight patients (264 teeth) who had NSRCT were reviewed at 5-14 months, postoperatively. Teeth with persistent post-treatment pain or discomfort, plus evidence of periapical healing were further monitored 0.

Candida species in patients with oral dysesthesia: A comparison of carriage among oral disease states.

Objectives: Oral dysesthesia (burning mouth syndrome) is characterized by a burning-like sensation of the oral mucosa. The etiology of this disorder is still unknown, however, associations with oral fungal carriage have been proposed and applied clinically. The aim of the this study was to compare oral Candida carriage in patients with oral dysesthesia with Candida carriage in patients with other commonly diagnosed oral diseases to clarify the relationship between Candida and oral dysesthesia.

Scalable whole-exome sequencing of cell-free DNA reveals high concordance with metastatic tumors.

Whole-exome sequencing of cell-free DNA (cfDNA) could enable comprehensive profiling of tumors from blood but the genome-wide concordance between cfDNA and tumor biopsies is uncertain. Here we report ichorCNA, software that quantifies tumor content in cfDNA from 0.1× coverage whole-genome sequencing data without prior knowledge of tumor mutations.

Low dose effect of bisphosphonates on hMSCs osteogenic response to titanium surface .

Since the 1980s, titanium (Ti) implants have been routinely used to replace missing teeth. This success is mainly due to the good biocompatibility of Ti and the phenomenon of osseointegration, with very early events at implant placement being important in determining good osseointegration. However, enhancing implant performance with coatings such as hydroxyapatite (HA) and calcium phosphate has proved largely unsuccessful.

Comparative genomics and transcriptomics of Pichia pastoris.

Background: Pichia pastoris has emerged as an important alternative host for producing recombinant biopharmaceuticals, owing to its high cultivation density, low host cell protein burden, and the development of strains with humanized glycosylation. Despite its demonstrated utility, relatively little strain engineering has been performed to improve Pichia, due in part to the limited number and inconsistent frameworks of reported genomes and transcriptomes. Furthermore, the co-mingling of genomic, transcriptomic and fermentation data collected about Komagataella pastoris and Komagataella phaffii, the two strains co-branded as Pichia, has generated confusion about host performance for these genetically distinct species.

This study reports the effect of transition metal (TM) substitution on the electrical and optical properties of BaCe0.9Sm0.1O3-δ (BCS).

A national follow-up survey of UK graduates opinion of undergraduate oral surgery teaching.

Introduction: A national follow-up survey was undertaken to determine whether dental graduates from 2009 perceived that their undergraduate oral surgery education had equipped them for general dental practice 4 years after graduating.

Materials And Methods: Graduates from the same 13 United Kingdom dental schools who had taken part in the original survey were invited to take part in this follow-up online survey. Their contact details were identified via the general dental council register, social media and alumni groups.

Automated pipeline for rapid production and screening of HIV-specific monoclonal antibodies using pichia pastoris.

Monoclonal antibodies (mAbs) that bind and neutralize human pathogens have great therapeutic potential. Advances in automated screening and liquid handling have resulted in the ability to discover antigen-specific antibodies either directly from human blood or from various combinatorial libraries (phage, bacteria, or yeast). There remain, however, bottlenecks in the cloning, expression and evaluation of such lead antibodies identified in primary screens that hinder high-throughput screening.
