Quantifying intraepithelial lymphocytes and subepithelial collagen band in microscopic colitis, extracting insights into the interrelationship of lymphocytic and collagenous colitis.

Ann Diagn Pathol 2021 Mar 31;52:151741. Epub 2021 Mar 31.

Department of Clinical Medicine, University of Copenhagen, Blegdamsvej 3B, 2200 Copenhagen, Denmark; Department of Medical Gastroenterology, Zealand University Hospital Koege, Lykkebækvej 1, 4600 Koege, Denmark.

Microscopic colitis (MC) is the umbrella term for the conditions termed lymphocytic colitis (LC) and collagenous colitis (CC). LC with thickening of the subepithelial collagen band or CC with increased number of intraepithelial T- lymphocytes (IELs) is often seen in MC and may lead to difficulties in correct histological classification. We investigated the extent of overlapping features of CC and LC in 60 cases of MC by measuring the exact thickness of the subepithelial collagen band in Van Gieson stained slides and quantifying number of IELs in CD3 stained slides by digital image analysis.

Cell Immunol 2021 Apr 8;364:104359. Epub 2021 Apr 8.

DST-NRF Centre of Excellence for Biomedical Tuberculosis Research, South African Medical Research Council Centre for Tuberculosis Research, Division of Molecular Biology and Human Genetics, Faculty of Medical and Health Sciences, Stellenbosch University, Cape Town, South Africa. Electronic address:

Conventional anti-tuberculosis (TB) therapies comprise lengthy antibiotic treatment regimens, exacerbated by multi-drug resistant and extensively drug resistant mycobacterial strains. We assessed the ability of all-trans retinoic acid (ATRA), as repurposed compound serving as host-directed therapy (HDT), to counteract the suppressive effects of myeloid-derived suppressor cells (MDSCs) obtained from active TB cases (untreated or during week one of treatment) on T-cell responsiveness. We show for the first time that MDSCs suppress non-specific T-cell activation and production of interleukin (IL)-2, IL-4, IL-13 and GM-CSF via contact-dependent mechanisms. Read More

Assessing recurrence of depression using a zero-inflated negative binomial model: A secondary analysis of lifelog data.

Psychiatry Res 2021 Apr 1;300:113919. Epub 2021 Apr 1.

Department of Health Promotion and Human Behavior, Kyoto University Graduate School of Medicine / School of Public Health, Kyoto, Japan.

When studying recurrence of depression, researchers should pay attention to cases where physicians' assessment corresponds to the patients' perception. However, they should also focus on potential signs of recurrence when the recurrence is suspected by the physicians but not the patients (false-negative zeros). Because false negatives can delay diagnosis and treatment, we aimed to investigate "sitting idly" as a predictor influencing no alert sign of recurrence and estimated the counts of recurrence of depression.
