Shear wave elastography (SWE) examination using ultrasound elastography (USE) is a popular imaging procedure for obtaining elasticity information of breast lesions. Elasticity parameters obtained through SWE can be used as biomarkers that can distinguish malignant breast lesions from benign ones. Furthermore, the elasticity parameters extracted from SWE can speed up the diagnosis and possibly reduce human errors. In this paper, Shearlet transform and local binary pattern histograms (LBPH) are proposed as an original algorithm to differentiate malignant and benign breast lesions...

Elder Neglect (EN) is the failure of a designated caregiver to meet the needs of a dependent older person. World EN prevalence, meta-analyzed in this study, is 1.0% or 1.8% according to different statistical methods. Referring alleged EN cases to Adult Protective Services (APSs) by healthcare workers (HCWs) is mandatory in many countries. However, only few claims are substantiated, as EN could be confused with Self-Neglect, neglect could be unintentional or due to caregiver unawareness. Screening tools are inaccurate and their use is discouraged by public health organizations, because they lead to too many false positives, which engulf the already overwhelmed APSs...

Opportunistic infections caused by Pneumocystis jirovecii, Cryptococcus neoformans, and ubiquitous airborne filamentous fungi have been recently reported in patients with hematological cancers historically considered at low risk for invasive fungal infections (IFIs), after receipt of the Bruton tyrosine kinase inhibitor ibrutinib. The spectrum and severity of IFIs often observed in these patients implies the presence of a complex immunodeficiency that may not be solely attributed to mere inhibition of Bruton tyrosine kinase...

Kristina J Nicholson, Linwah Yip
PURPOSE OF REVIEW: Correct identification of malignancy in cytologically indeterminate thyroid nodules is a diagnostic challenge, leading to potentially unnecessary surgery in patients for whom final histology is benign. Similarly, many patients with differentiated thyroid cancer (DTC) undergo aggressive surgical management of tumors, which may ultimately have low-risk histologic features. Use of molecular testing strategies can aid in both the diagnosis of indeterminate thyroid nodules and preoperative risk stratification of DTC...

To explore underlying molecular mechanisms and identify novel lipid biomarkers promising for colorectal cancer (CRC) diagnosis, a continuous-flow two dimensional liquid chromatography-quadrupole time-of-flight mass spectrometry (2D LC-QToF/MS) method was employed to comprehensively measure lipid species in human plasma of CRC patients and healthy controls. With a total of 427 annotated lipid species, we identified 64 lipid species with corrected p value less than 0.05 and fold change more than 1.5. These significantly altered lipid species were mainly involved in glycerolipids and glycerophospholipids metabolism and sphingolipids metabolism...

OBJECTIVE: The presence of ectopic or supernumerary breast tissue is a rare event, related to a not complete regression of breast tissue along the milk line. Primary ectopic breast cancer of the axilla can create many difficulties in differential diagnosis with subsequent delayed specific treatments. The incidence of ectopic breast tissue is 0.2-6%, and the axilla is the most common site involved. In this tissue, the same physiologic and pathologic changes as seen in ectopic breast tissue may occur, including carcinoma formation...

REVIEW
Mattie J Casey, Rodney A Stewart
Neuroblastoma is a pediatric solid tumor arising from embryonic neural crest progenitor cells that normally generate the peripheral sympathetic nervous system. As such, the location of neuroblastoma tumors is correlated with the distribution of major post-ganglionic clusters throughout the sympathetic chain, with the highest incidence in the adrenal medulla or lumbar sympathetic ganglia (~65%). Neuroblastoma is an enigmatic tumor that can spontaneously regress with minimal treatment or become highly metastatic and develop resistance to aggressive treatments, including radiation and high-dose chemotherapy...

Soogeun Kim, Seung Ho Lee, Sun Young Min, Kyung Min Byun, Soo Yeol Lee
A dual-modal approach using Raman spectroscopy and optical pH sensing was investigated to discriminate between normal and cancerous tissues. Raman spectroscopy has demonstrated the potential for in vivo cancer detection. However, Raman spectroscopy has suffered from strong fluorescence background of biological samples and subtle spectral differences between normal and disease tissues. To overcome those issues, pH sensing is adopted to Raman spectroscopy as a dual-modal approach. Based on the fact that the pH level in cancerous tissues is lower than that in normal tissues due to insufficient vasculature formation, the dual-modal approach combining the chemical information of Raman spectrum and the metabolic information of pH level can improve the specificity of cancer diagnosis...

Identification of genes specifically deregulated in prostate adenocarcinoma may lead to discovery of new oncogenes/tumour suppressors with clinical relevance for diagnosis, prognosis and/or therapy. CXXC5 is a gene encoding a retinoid-inducible nuclear factor, whose overexpression in breast tumours, metastatic malignant melanomas and papillary thyroid carcinoma has been recently reported. We previously found differential expression of CXXC5 transcripts in metastatic prostate cancer cell lines of both rat and human origin...

The digestive system cancers are leading cause of cancer-related death worldwide, and have high risks of morbidity and mortality. More and more long non-coding RNAs (lncRNAs) have been studied to be abnormally expressed in cancers and play a key role in the process of digestive system tumour progression. Plasmacytoma variant translocation 1 (PVT1) seems fairly novel. Since 1984, PVT1 was identified to be an activator of MYC in mice. Its role in human tumour initiation and progression has long been a subject of interest...
