Interestingly, MSCHS provided better therapeutic outcomes compared to MSC3D, partially due to their enhanced survival capacity in vivo. Moreover, we found that MSC-derived paracrine factor, prostaglandin E2 (PGE2), can directly drive the epithelial regeneration process by inducing specialized tissue-repairing cell generation using the intestinal organoid culture. Importantly, MSC3D and MSCHS displayed an outstanding regeneration-inducing potency compared to MSC2D owing to their superior PGE2 secretion. Taken together, we suggest a convergent strategy of MSCHS formation with reactive oxygen species (ROS) scavenger, QUR, which can maximize the inflammation-attenuating and tissue-repairing capacity of MSCs, as well as the engraftment efficiency after transplantation.
Genetic predisposition is reportedly involved in early-onset oral cancer, although the genetic basis of this cancer remains unclear. The major histocompatibility complex class I-related chain A (MICA) plays a crucial role in eliminating malignant tumors by activating NKG2D, the natural killer (NK) receptor. MICA polymorphism might affect its binding to NKG2D. We aimed to find whether MICA gene microsatellite polymorphism is involved in the risk of oral squamous cell carcinoma (OSCC) development in a Japanese population.

We recruited 386 patients with OSCC and 103 healthy controls. Genomic DNA was analyzed by PCR for microsatellite repeat polymorphism in the transmembrane region of the MICA gene. Oxaliplatin in vitro The groups were compared for the prevalence of various alleles and their association with disease prognosis and survival.

We found that adolescents and young adults (AYA) with OSCC were more likely to have the MICA A5.1 homozygous genotype than healthy controls (P=0.0001), but their survival rate was higher than with other MICA genotypes (P=0.0185).

These results suggest that cancer's immune escape is facilitated by MICA's failure to activate the NK cells. MICA A5.1 homozygosity plays a role in individual susceptibility to OSCC, increasing the risk of early-onset oral cancer. However, such patients have a better prognosis than those with other MICA genotypes.

Human Papilloma Virus is associated with the development of cancers in the head and neck region. We have witnessed, in the last decades, an increase in number of cases directly related to HPV infection, in particular in the Western Countries. Recently the FDA expanded the indications for Gardasil-9® to include the prevention of head and neck cancer. Objective of this paper is to review the evidence supporting its use.

Bibliographic review enquiring Medline, Web of Science and the Cochrane Library to assess the efficacy of vaccination against oncogenic HPV in the prevention of head and neck squamous cell carcinoma.

Two prospective and 4 retrospective studies have evaluated vaccination in prevention of head and neck cancer, using persistent oral infection as surrogate of efficacy. All studies showed lower prevalence of oral infection up to 4 years following vaccination. Vaccine efficacy was estimated between 88 and 93.3%. Because of low vaccine coverage the estimated population-level effect against oral Haccination and prevention of persistent oral infection and investigate the duration of efficacy, which is crucial in its effectiveness against HNSCC.
This systematic review and meta-analysis aimed to develop an evidence-based summary of current knowledge of bone metastases (BMs) in neuroendocrine neoplasms (NENs), inform diagnosis and treatment and standardise management between institutions.

PubMed, Medline, EMBASE and meeting proceedings were searched for eligible studies reporting data on patients with BMs and NENs of any grade of differentiation and site; poorly-differentiated large/small cell lung cancer were excluded. Data were extracted and analysed using STATA v.12. Meta-analysis of proportions for calculation of estimated pooled prevalence of BM and calculation of weighted pooled frequency and weighted pooled mean for other variables of interest was performed .

A total of 149 studies met the eligibility criteria. Pooled prevalence of BMs was 18.4% (95% CI 15.4-21.5). BMs were mainly metachronous with initial diagnosis of NEN (61.2%) and predominantly osteoblastic; around 61% were multifocal, with a predisposition in axial skeleton. PET/CT se NENs remain underdiagnosed and undertreated. Recommendations for management of BMs derived from current knowledge are provided. Prospective studies to inform management are required.
Predictive biomarkers of Parkinson's Disease progression are needed to expedite neuroprotective treatment development and facilitate prognoses for patients. This work uses measures derived from resting-state functional magnetic resonance imaging, including regional homogeneity (ReHo) and fractional amplitude of low frequency fluctuations (fALFF), to predict an individual's current and future severity over up to 4 years and to elucidate the most prognostic brain regions.

ReHo and fALFF are measured for 82 Parkinson's Disease subjects and used to train machine learning predictors of baseline clinical and future severity at 1 year, 2 years, and 4 years follow-up as measured by the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS). Predictive performance is measured with nested cross-validation, validated on an external dataset, and again validated through leave-one-site-out cross-validation. Important predictive features are identified.

The models explain up to 30.4% of the variance in current MDS-UPDRS scores, 55.8% of the variance in year 1 scores, and 47.1% of the variance in year 2 scores (p<0.0001). For distinguishing high and low-severity individuals at each timepoint (MDS-UPDRS score above or below the median, respectively), the models achieve positive predictive values up to 79% and negative predictive values up to 80%. Higher ReHo and fALFF in several regions, including components of the default motor network, predicted lower severity across current and future timepoints.

These results identify an accurate prognostic neuroimaging biomarker which may be used to better inform enrollment in trials of neuroprotective treatments and enable physicians to counsel their patients.
