Abstract
Abstract
Introduction
The Wirral Teletriage Service provides non-urgent clinical support to Wirral Care Homes in order to help avoid unnecessary hospital admissions for their residents. It also aims to provide quicker access to clinical assessment than via NHS 111 and to provide this care in the patient’s residence wherever possible.
Methods
Care homes call the Teletriage service when they have concerns about the health of one of their residents. The Teletriage nurse undertakes a clinical assessment of the resident remotely via Skype. Care Homes have been provided with a secure NHS email address to facilitate secure sharing of data. They have also been provided with iPads and training for their staff. After being assessed by Teletriage, residents are signposted to the most appropriate care pathway for their needs.
Results
76 Care Homes have signed up to the service. On average, the Teletriage Service receives 300-400 calls a month. In an 18 month period, the number of calls to NHS 111 have reduced by 76%. Out of all the calls to Teletriage, 22% of patients were managed by the Teletriage team with no onward referral, 57% were managed via community services e.g GPs, Community Geriatricians, and 10% were referred to the ambulance service. Emergency Health Care Plans (EHCPs), Preferred Priorities of Care and EOL (End of Life) wishes are taken into account.
Conclusions
The Teletriage project has reduced the number of phone calls to NHS 111 and the ambulance service, and subsequently has reduced the number of patients conveyed to hospital by 12%. The Teletriage nurses work very closely with various community services as well as GPs, NWAS and Community Geriatricians. The ongoing training and education provided to the Care Home Staff means that overall there has been good engagement with the project from the majority of the Wirral Care Homes.

Sci Rep 2020; 10:927.

Abstract
Being born small (SGA) or large for gestational age (LGA) is associated with adverse birth outcomes and metabolic diseases in later life of the offspring. It is known that aberrations in growth during gestation are related to altered placental function. Placental function is regulated by epigenetic mechanisms such as DNA methylation. Several studies in recent years have demonstrated associations between altered patterns of DNA methylation and adverse birth outcomes. However, larger studies that reliably investigated global DNA methylation are lacking. The aim of this study was to characterize global placental DNA methylation in relationship to size for gestational age. Global DNA methylation was assessed in 1023 placental samples by LC-MS/MS. LGA offspring displayed significantly higher global placental DNA methylation compared to appropriate for gestational age (AGA; p < 0.001). ANCOVA analyses adjusted for known factors impacting on DNA methylation demonstrated an independent association between placental global DNA methylation and LGA births (p < 0.001). Tertile stratification according to global placental DNA methylation levels revealed a significantly higher frequency of LGA births in the third tertile. Furthermore, a multiple logistic regression analysis corrected for known factors influencing birth weight highlighted an independent positive association between global placental DNA methylation and the frequency of LGA births (p = 0.001).

Abstract
AIMS To investigate the associations among heteroplasmy levels (i.e. the proportions of mutant and wild-type mitochondrial DNA in the same cell), mitochondrial function and clinical severity of the m.3243A>G mutation. METHODS A total of 17 participants carrying the m.3243A>G mutation and 17 sex- and age-matched healthy controls were included in this study. Heteroplasmy levels of the m.3243A>G mutation in leukocytes, saliva and urine sediment were determined by pyrosequencing. The clinical evaluation included endocrinological, audiological and ophthalmological examinations. Mitochondrial function was determined in peripheral blood mononuclear cells isolated from participants. RESULTS Heteroplasmy levels in urine sediment were higher than those in leukocytes and saliva. Reduced levels of adenosine triphosphate and mitochondrial membrane potential, and increased reactive oxygen species production were observed in mutant peripheral blood mononuclear cells (all P < 0.05). Linear regression analysis indicated that higher heteroplasmy levels in peripheral blood leukocytes were associated with increased levels of glycated albumin and HbA1c , and decreased total hip bone mineral density T-score after adjustment for age and sex (all P < 0.05). Furthermore, mitochondrial membrane potential was independently associated with bone mineral density T-score at the femoral neck (P < 0.05). CONCLUSIONS Heteroplasmy levels in peripheral blood leukocytes and mitochondrial membrane potential in peripheral blood mononuclear cells were closely associated with clinical manifestations and were valuable for evaluation of the clinical severity of the m.3243A>G mutation.

Abstract
BACKGROUND Small non-coding RNAs (sncRNAs) accomplish a huge variety of biological functions. Over the past decade, we have witnessed the substantial progress in the epididymal sncRNA studies. In the Epididymis 7, we had the true privilege of having a whole session to share our findings and exchange ideas on the epididymal sncRNA studies. OBJECTIVES This mini-review attempts to provide an overview of what is known about the sncRNAs in the mammalian epididymis and discuss the future directions in this field. METHODS We surveyed literature regarding the sncRNA studies in the mammalian epididymis, and integrated some of our unpublished findings as well. We focus on the progress in methodology and the advances in our understanding of the expression and functions of epididymal sncRNAs. RESULTS AND DISCUSSION The applications of high-throughput approaches have made great contributions in the discovery of new sncRNA species and profiling their dynamics in the epithelial cells, the passing spermatozoa, and the luminal environment. The diverse classes of epididymal sncRNAs exert important biological functions from the in situ regulation of epididymal gene expression to the epigenetic inheritance in the offspring. CONCLUSION Although still in its infancy, we believe that the research on epididymal sncRNAs will not only lead to a better understanding of their physiological and pathological functions, but also contribute to the whole landscape of the RNA field.

Abstract
Only 5-10% of all breast and ovarian cancers have been attributed to inherited mutation. In unselected breast cancer patients, prevalence of germline BRCA 1 & 2 is about 2%. In Ashkenazi Jewish population the prevalence is estimated to be 11.7%. The rate of mutations in other populations has not been well characterized. The purpose of this study is to identify and characterize the risk of genetic mutations in an ethnically diverse population referred for genetic testing according to NCCN guidelines.

Abstract
OBJECTIVE IRX3 expression has been functionally associated in obesity-associated long-distance susceptibility loci, but the effect of the IRX3 genetic variants on human obesity and obesity-related metabolism remains uncertain. METHODS To determine the genetic role of IRX3, we conducted a molecular epidemiological analysis using three haplotype tagging single nucleotide polymorphisms (SNPs; rs8053360, rs3751723 and rs12445085) and one nonsynonymous SNP (rs1126960) at the IRX3 locus in 333 junior and senior high school students from a northeast Chinese population. RESULTS We identified significant associations between IRX3 SNPs and birth weight, body mass index (BMI), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and AST/ALT ratio. The rs8053360 CC and rs1126960 GG genotypes were associated with increased birth weight and BMI, especially in females. Individuals with the rs12445085 TT genotype had significantly higher levels of AST and ALT, whereas individuals with the rs1126960 GG genotype had a significantly lower AST/ALT ratio than did individuals with other genotypes. However, no significant relationships were found between any of the IRX3 SNPs and metabolic syndrome or diabetes. CONCLUSIONS IRX3 genetic variants associate with birth weight, BMI and AST/ALT-related transaminase metabolism, supporting the role of IRX3 as an obesity-associated susceptibility gene.

Abstract
Combined multiple 2D views (proximal, anterior and ventral aspects) of the sagittal otolith are proposed here as a method to capture shape information for fish classification. Classification performance of single view compared with combined 2D views show improved classification accuracy of the latter, for nine species of Sciaenidae. The effects of shape description methods (shape indices, Procrustes analysis and elliptical Fourier analysis) on classification performance were evaluated. Procrustes analysis and elliptical Fourier analysis perform better than shape indices when single view is considered, but all perform equally well with combined views. A generic content-based image retrieval (CBIR) system that ranks dissimilarity (Procrustes distance) of otolith images was built to search query images without the need for detailed information of side (left or right), aspect (proximal or distal) and direction (positive or negative) of the otolith. Methods for the development of this automated classification system are discussed.
