HIV Status Does Not Worsen Oral Health Outcomes.

J Clin Periodontol 2019 Apr 21. Epub 2019 Apr 21.

Department of Oral Biology, School of Dental Medicine, University of Pittsburgh.

Last January 31 , Journal of Clinical Periodontology just made available the report titled "A Retrospective Analysis of Dental Implant Survival in HIV Patients", which concluded that "implants placed in HIV-positive patients had similar survival rates as HIV-negative patients." These data support our hypothesis that infection by HIV does not lead to worse oral health outcomes, including worse periodontitis. We looked 6,092 individuals and selected all HIV-positive subjects (N=73) and matched them by age, sex, ethnicity, and smoking habits with 261 HIV-negative control subjects. Read More

Factors associated with antibiotic prescribing for adults with acute conditions: an umbrella review across primary care and a systematic review focusing on primary dental care.

J Antimicrob Chemother 2019 Apr 19. Epub 2019 Apr 19.

University of Leeds/Leeds Teaching Hospitals NHS Trust, Leeds, UK.

Introduction: One way to slow the spread of resistant bacteria is by improved stewardship of antibiotics: using them more carefully and reducing the number of prescriptions. With an estimated 7%-10% of antibiotic prescriptions globally originating from dental practices and up to 80% prescribed unnecessarily, dentistry has an important role to play. To support the design of new stewardship interventions through knowledge transfer between contexts, this study aimed to identify factors associated with the decision to prescribe antibiotics to adults presenting with acute conditions across primary care (including dentistry).

Dental Infection Cause of Flap Loss in Cleft Palate Repair.

J Craniofac Surg 2019 Apr 12. Epub 2019 Apr 12.

MGM Dental College and Hospital, Navi Mumbai, India.

Flap necrosis is a very common complication encountered after cleft palate repair, especially in uni-pedicled flaps. Many causes have been attributed to this complication but very limited data is available in the literature on dental infection as the cause of flap necrosis. This report of a case describes loss of flap caused due to a periapical granuloma of dental origin impinging on the pedicle causing suspected thrombosis of the pedicle resulting in flap necrosis.

Adenovirus E1B-55K targets SMARCAL1 for degradation during infection and modulates cellular DNA replication.

J Virol 2019 Apr 17. Epub 2019 Apr 17.

Institute of Cancer & Genomic Sciences Institute of Metabolism & Systems Research; College of Medical and Dental Sciences, The University of Birmingham, United Kingdom, B15 2TT

Here we show that the cellular DNA replication protein and ATR substrate, SMARCAL1, is recruited to viral replication centres early during adenovirus infection and is then targeted in an E1B-55K/E4orf6 and Cullin Ring Ligase-dependent manner for proteasomal degradation. In this regard we have determined that SMARCAL1 is phosphorylated at S123, S129 and S173 early during infection, in an ATR- and CDK- dependent manner, and that pharmacological inhibition of ATR and CDK activities attenuates SMARCAL1 degradation. SMARCAL1 recruitment to viral replication centres was shown to be largely dependent upon SMARCAL1 association with the RPA complex, whilst Ad-induced SMARCAL1 phosphorylation also contributed towards SMARCAL1 recruitment to viral replication centres, albeit to a limited extent.

Today's vaccination policies in Italy: The National Plan for Vaccine Prevention 2017-2019 and the Law 119/2017 on the mandatory vaccinations.

Ann Ig 2019 Mar-Apr;31(2 Supple 1):54-64

Department of Clinical and Experimental Medicine, Unit of Infectious Diseases, University of Messina, Italy.

The National Plan for Vaccine Prevention 2017-2019 has expanded the vaccination offer including new vaccines, enlarging the target population and introducing for the first time in Italy a life-course approach to vaccination. A "lifetime immunization schedule" is aimed to reduce the burden and the related costs of vaccine-preventable diseases through effective vaccination programs. However, to counteract the national steady downward trend in the uptake of vaccinations that caused a drop of the vaccination coverage below the 95% threshold to allow herd immunity, it was decided to make 10 vaccinations mandatory by the law 119/2017.

Small-Molecule Host-Defense Peptide Mimetic Antibacterial and Antifungal Agents Activate Human and Mouse Mast Cells via Mas-Related GPCRs.

Cells 2019 Apr 3;8(4). Epub 2019 Apr 3.

Department of Pathology, University of Pennsylvania, School of Dental Medicine, Philadelphia, PA 19104, USA.

Host-defense peptides (HDPs) have an important therapeutic potential against microbial infections but their metabolic instability and cellular cytotoxicity have limited their utility. To overcome these limitations, we utilized five small-molecule, nonpeptide HDP mimetics (smHDPMs) and tested their effects on cytotoxicity, antimicrobial activity, and mast cell (MC) degranulation. None of the smHDPMs displayed cytotoxicity against mouse 3T3 fibroblasts or human transformed liver HepG2 cells. Read More

Management of Deep Caries and the Exposed Pulp.

Int Endod J 2019 Apr 15. Epub 2019 Apr 15.

Division of Restorative Dentistry & Periodontology, Dublin Dental University Hospital, Trinity College Dublin, Dublin, Ireland.

Caries prevalence remains high throughout the world, with the burden of disease increasingly affecting older and socially disadvantaged groups in Western cultures. If left untreated, caries will advance through dentine stimulating pulpitis and eventually pulp infection and necrosis; however, if conservatively managed pulpal recovery occurs even in deep carious lesions. Traditionally, deep caries management was destructive with non-selective (complete) removal of all carious dentine; however, the promotion of minimally invasive biologically based treatment strategies has advocated for selective (partial) caries removal and a reduced risk of pulp exposure.

AMPs as Anti-biofilm Agents for Human Therapy and Prophylaxis.

Adv Exp Med Biol 2019 ;1117:257-279

Department of Microbiology and Parasitology, University of Navarra, Pamplona, Spain.

Microbial cells show a strong natural tendency to adhere to surfaces and to colonize them by forming complex communities called biofilms. In this growth mode, biofilm-forming cells encase themselves inside a dense matrix which efficiently protects them against antimicrobial agents and effectors of the immune system. Moreover, at the physiological level, biofilms contain a very heterogeneous cell population including metabolically inactive organisms and persisters, which are highly tolerant to antibiotics.

Authors:
V E Toy M O Uslu

Niger J Clin Pract 2019 Apr;22(4):445-453

Department of Periodontology, Faculty of Dentistry, Inonu University, Malatya, Turkey.

The pathogenesis of periodontal disease is not solely based on microbial dental plaque but is the result of the multifactorial and complex interaction between infection and host response. Many studies in the literature have demonstrated the differences between individuals in terms of host immune response and the presence of genetic components in numerous pathological conditions. Therefore, periodontitis may be defined as a complex genetic disorder with a phenotype formed by the genetic structure and environmental factors in the affected individual. Read More

Sequential Sensing by TLR2 and Mincle Directs Immature Myeloid Cells to Protect against Invasive Group A Streptococcal Infection in Mice.

Cell Rep 2019 Apr;27(2):561-571.e6

Department of Mycobacteriology, Leprosy Research Center, National Institute of Infectious Diseases, 4-2-1 Aoba-cho, Higashimurayama-shi, Tokyo 189-0002, Japan.

Severe invasive group A Streptococcus (GAS) infection evades anti-bacterial immunity by attenuating the cellular components of innate immune responses. However, this loss of protection is compensated for by interferon (IFN)-γ-producing immature myeloid cells (γIMCs), which are selectively recruited upon severe invasive GAS infection in mice. Here, we demonstrate that γIMCs provide this IFN-γ-mediated protection by sequentially sensing GAS through two distinct pattern recognition receptors. Read More
