Sunshine is an Important Determinant of Vitamin D Status Even Among High ‐dose Supplement Users: Secondary Analysis of a Randomized Controlled Trial in Crohn's Disease Patients

This study was a secondary analysis of an RCT of 92 Crohn's disease patients in remission (49% female, median age  = 44). Participants were randomized to 2000 IU day−1 of vitamin D3 or placebo for 1 year, with 25 ‐hydroxyvitamin D (25(OH)D) being measured at baseline and every 4 months. Based on participant's place of residence, daily ambient UVB dose at wavelengths that can induce vitamin D synthesis (D‐UVB) was obtained. Cumulative and weighted ambient D‐UVB (cw‐D‐UVB) exposure prior to each blo od draw was calculated for each participant. Linear regression analysis and multilevel modeling were used to examine the association between UVB exposure, supplementation and 25(OH)D concentration. There was considerable annual variation in D‐UVB, cw‐D‐UVB and 25(OH)D. Both supplementation and cw‐D‐UVB were found to be strongly associated with 25(OH)D: in multilevel model, an increase of approximately 6 nmol L−1 for every 100  kJ m−2 in cw ‐D‐UVB was found, among those receiving placebo and supplementation (P

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.

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...
