The hidden cost of disease: I. Impact of the first incidence of mastitis on production and economic indicators of primiparous dairy cows.

J Dairy Sci 2021 Apr 14. Epub 2021 Apr 14.

Department of Animal Science, McGill University, Ste-Anne-de-Bellevue, QC H9X 3V9, Canada.

Mastitis is a highly prevalent disease, which negatively affects cow performance, profitability, welfare, and longevity. The objectives of this study were (1) to quantify the impact of the first instance of mastitis, at different stages of lactation, on production and economic performance, and (2) to further quantify the impact of the first instance of mastitis when only cows that remain in the herd for at least 100 d in milk (DIM) and those that remain for 305 DIM are included in the analysis. A retrospective longitudinal study was conducted using data from existing animal health record files and Dairy Herd Improvement records. Read More

Recovery of dynamic stability during slips unaffected by arm swing in people with Parkinson's Disease.

PLoS One 2021 6;16(4):e0249303. Epub 2021 Apr 6.

School of Human Kinetics, University of Ottawa, Ottawa, ON, Canada.

The arm elevation strategy assists in recovering stability during slips in healthy young and elderly individuals. However, in people with Parkinson's Disease, one of the main motor symptoms affecting the upper limbs is reduced arm swing which intensifies throughout the course of the disease before becoming absent. This holds direct implications for these individuals when encountering slips as the arm elevation strategy is an integral component in the interlimb slip response to restore stability. Read More

Towards in-vivo label-free detection of brain tumor margins with epi-illumination tomographic quantitative phase imaging.

Biomed Opt Express 2021 Mar 25;12(3):1621-1634. Epub 2021 Feb 25.

School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA 30332, USA.

Brain tumor surgery involves a delicate balance between maximizing the extent of tumor resection while minimizing damage to healthy brain tissue that is vital for neurological function. However, differentiating between tumor, particularly infiltrative disease, and healthy brain in-vivo remains a significant clinical challenge. Here we demonstrate that quantitative oblique back illumination microscopy (qOBM)-a novel label-free optical imaging technique that achieves tomographic quantitative phase imaging in thick scattering samples-clearly differentiates between healthy brain tissue and tumor, including infiltrative disease.

[Micrographic surgery and its variants].

Rev Med Suisse 2021 Mar;17(732):630-634

Unité de dermatochirurgie, Service de dermatologie et vénéréologie, Département des spécialités de médecine, HUG, 1211 Genève 14.

Cutaneous tumours can be ill-delineated and subclinical tumour can be missed when using the usual methods of pathology processing because only less than 1 % of the margin is examined. Micrographic surgery was developed to allow for examination of 100 % of the margin. It reduces the recurrence rate and spares healthy tissue thus reducing lesion size and facilitating reconstruction.

Agriculture and Agri-Food Canada, 4902 Victoria Avenue North, Vineland Station, ON L0R 2E0, Canada, Vineland, Ontario, Canada;

Moldy core is a fungal disease of apple fruits that is characterized by mycelial growth in the seed locules and is sometimes accompanied by penetration of the immediate surrounding flesh. The disease can go undetected until the fruit is cut open, as no external symptoms appear on the fruit. Alternaria, Aspergillus, Cladosporium, Coniothyrium, Epicoccum, Phoma and Stemphylium are some of the common pathogens associated with moldy core (Serdani et al. Read More
