Alterations of salivary microbial community associated with oropharyngeal and hypopharyngeal squamous cell carcinoma patients.

Alterations of salivary microbial community associated with oropharyngeal and hypopharyngeal squamous cell carcinoma patients. Arch Microbiol. 2019 Dec 12;: Authors: Panda M, Rai AK, Rahman T, Das A, Das R, Sarma A, Kataki AC, Chattopadhyay I Abstract The highest number (35.1% of global incident cases) of new oropharyngeal (OP) and hypopharyngeal (HP) cancer cases was reported in South-Central Asia. The highest incidence of HP cancer in India was reported in East Khasi Hills District of Meghalaya, Aizawl District of Mizoram, and Kamrup Urban District of Assam. HP and OP cancer showed the highest mortality rate, worst prognoses and the highest rate of nodal metastases and distant metastases. Thus, research is required to detect specific biomarkers for early prevention and diagnosis for these cancers. Oral microbiome signatures in saliva are considered as a potential diagnostic biomarker for OP and HP cancer. Bacterial profile alterations in OP and HP cancer have not been reported in India population, to establish the association of oral bacteria in the progression of OP and HP cancer; we studied bacterial communities in saliva of eight OP and seven HP cancer patients as compared to healthy controls using 16S rRNA V3-V4 region sequencing. The higher abundance of Haemophilus parainfluenzae, Haemophilus influenzae and Prevotella copri and lower abundance of Rothia mucilaginosa, Aggregatibacter segnis, Veillonella dispar, Prevotella nanceiensis, Rothia aeria,...

Authors: DiCaprio MR, Abousayed MM, Kambam MLR Abstract Melanoma is an aggressive form of skin cancer associated with significant morbidity and mortality. Although commonly seen in dermatologist clinics, orthopaedic surgeons must be aware of these lesions in various ways. The five common musculoskeletal manifestations of melanoma will be discussed as well as the epidemiology, pathogenesis, diagnosis, staging, treatment, and prognosis of melanoma. With an index of suspicion and awareness of melanoma, a thorough history and detailed physical examination are critical in establishing a diagnosis. An adequately performe...

CONCLUSION: Ultrasound and MRI have similar diagnostic performance for detecting parametrial infiltration in women with cervical cancer. This might have relevance from the clinical point of view, since ultrasound is cheaper than MRI. PMID: 32096793 [PubMed - as supplied by publisher]

CONCLUSION: By using the combination of ultrasound modes, this approach achieves high performance compared with the single mode and other fusion strategies. Our methodology may be a beneficial tool for the early detection and diagnosis of breast cancer. PMID: 32096788 [PubMed - as supplied by publisher]

CONCLUSIONS: In cases of BCCs with thickness of ≤1 mm, there was a high correlation (r=0.870) of the tumor spread depth between micromorphological measurements and the results obtained using a 75 MHz transducer and in cases of BCCs with thickness of>1 mm, a very high correlation (r=0.951) of the tumor spread depth was observed between histomorphometry and30 MHz transducer measurements.

Authors: Liu H, Li H, Li Y, Yin S, Boimel P, Janopaul-Naylor J, Zhong H, Xiao Y, Ben-Josef E, Fan Y Abstract Radiomic approaches have achieved promising performance in prediction of clinical outcomes of cancer patients. Particularly, feature dimensionality reduction plays an important role in radiomic studies. However, conventional feature dimensionality reduction techniques are not equipped to suppress data noise or utilize latent supervision information of patient data under study (e.g. difference in patients) for learning discriminative low dimensional representations. To achieve feature dimensionality reduction...
