While rGO-Ti substrates significantly increased cell proliferation after 7 days of incubation, they significantly promoted ALP activity and matrix mineralization, which are early and late differentiation markers, respectively.

It is suggested that rGO-Ti substrates can be effectively utilized as dental and orthopedic bone substitutes since these graphene derivatives have potent effects on stimulating the osteogenic differentiation of hMSCs and showed superior bioactivity and osteogenic potential.

Rare homozygous and compound heterozygous premature termination codon (PTC) mutations in the Vacuolar Protein Sorting 13 homolog C gene (VPS13C) are associated with early-onset recessive PD. We observed in two siblings with early-onset age ( less then  45) and autopsy confirmed DLB, compound heterozygous missense mutations in VPS13C, p.Trp395Cys and p.Ala444Pro, inherited from their healthy parents in a recessive manner. In lymphoblast cells of the index patient, the missense mutations reduced VPS13C expression by 90% (p = 0.0002). Subsequent, we performed targeted resequencing of VPS13C in 844 LBD patients and 664 control persons. Using the optimized sequence kernel association test, we obtained a significant association (p = 0.0233) of rare VPS13C genetic variants (minor allele frequency ≤ 1PTC mutations in VPS13C, combinations of rare recessive compound heterozygous missense mutations reduce VPS13C expression and contribute to increased risk of LBD.

Close margins influence treatment and outcome in patients with oral squamous cell carcinoma (OSCC). This study evaluates 187 cases of surgically treated OSCC regarding the impact of close margins on recurrence-free survival (RFS) and disease-specific survival (DSS).

Predictors of worsened outcome were identified using Kaplan-Meier analysis and multivariate Cox regression analysis.

Tumour size [HR1.70(0.95-3.08)], nodal status [HR2.15(1.00-4.64)], presence of extracapsular spread (ECS) [HR6.36(2.41-16.74)] and smoking history [HR2.87(1.19-6.86)] were associated with worsened RFS. Similar factors were associated with worsened DSS. Close margins did not influence RFS or DSS.

While most conventional risk factors for OSCC conferred a worsened outcome, close margins did not. One explanation for this would be that close margins (< 5 mm) are equivalent to clear margins and the cutoff definition for a close margin should be re-evaluated. Lack of standardized pathology could also reduce accuracy of reporting of close surgical margins.

Psychotic illnesses can have a major impact on those who experience them. Timely treatment for psychosis is important and friends, family members and the public can be a facilitating factor in social support and professional help-seeking. Expert consensus guidelines on how to provide mental health first aid to a person experiencing psychosis were developed in 2008. This Delphi study aimed to redevelop the guidelines to reflect current evidence.

The Delphi consensus method was used to determine which helping strategies should be included in the redeveloped guidelines. A systematic search of grey and academic literature was undertaken to identify strategies on how a member of the public can assist someone experiencing psychosis. These strategies were organised into questionnaire statements. Two expert panels-one comprising people with lived experience (Carers and Consumers) and one of professionals-completed three consecutive rounds of online survey questionnaires to rate the importance of each helping stattailed instruction for members of the public on how to provide mental health first aid to assist a person experiencing psychosis. The guidelines are available to the public and will be used to update the Mental Health First Aid courses.

More evidence is emerging on the role of surface decontamination for reducing hospital-acquired infection (HAI). Timely and adequate removal of environmental pathogens leads to measurable clinical benefit in both routine and outbreak situations.

This systematic review aimed to evaluate published studies describing the effect of automated technologies delivering hydrogen peroxide (H202) or ultra-violet (UV) light on HAI rates.

A systematic review was performed using relevant search terms. Databases were scanned from January 2005 to March 2020 for studies reporting clinical outcome after use of automated devices on healthcare surfaces. Information collected included device type, overall findings; hospital and ward data; study location, length and size; antimicrobial consumption; domestic monitoring; and infection control interventions. Study sponsorship and duplicate publications were also noted.

While there are clear benefits from non-touch devices in vitro, we found insufficient objective assessment o-outbreak studies lacked an appropriate control group and were potentially compromised by industry sponsorship. Concern over HAI encourages delivery of powerful disinfectants for eliminating pathogens without appreciating toxicity or cost benefit. Routine use of these devices requires justification from standardized and controlled studies to understand how best to manage contaminated healthcare environments.
