Hyperchromatic crowded groups (HCGs) are often classified as atypical squamous cells, cannot exclude a high grade squamous intraepithelial lesion (ASC-H) on ThinPrep Pap tests. This study reports on the association of HCG's with high grade squamous intraepithelial lesions (HSIL) involving endocervical glands. Over a 3-year period (January 1, 2018-December 31, 2020), 115 (0.2%) of 63,817 Pap tests were diagnosed as ASC-H. Histologic follow-up was available in 76 (66%) cases; 42 (55%) cervical biopsies; and 34 (45%) cervical cones/LEEPs. Based on the histologic results, 49 ASC-H cases showed HSIL/CIN 3 and form the basis of this study. ThinPrep Pap tests showed two cell patterns; atypical immature squamous metaplastic cells and HCGs, each of which was difficult to distinguish from HSIL. On histologic correlation all 10 ASC-H Pap Tests with individual atypical immature squamous metaplastic cells showed HSIL/CIN 3 without endocervical gland involvement and 37 (95%) of the 39 Pap Tests with HCGs showed HSIL/CIN 3 with endocervical gland involvement. The results of this study support the premise that a subset of HCGs represent endocervical gland involvement by HSIL as opposed to a glandular lesion; in particular endocervical adenocarcinoma in-situ.

Glial development is usually investigated through perturbations of host genetics, although non-host-derived signalling molecules can also regulate glial cells. Indeed, gut microbiome colonisation and the presence of microbiome-derived factors in the blood coincide with glial cell development. Emerging data suggest that the gut microbiome can regulate gliogenesis, myelination and glial epigenetics. Neurodegenerative diseases are characterised by changes in the gut microbiome and glial dysfunction. This perspective discusses the ways in which microbiome-derived molecules can engage in cross-talk with glial cells during development and in dysfunctional glial diseases.The revised Common Rule requires using a single institutional review board (sIRB) for U.S.-based, multisite, nonexempt, federally conducted or supported research with human participants. The 21st Century Cures Act directs the Department of Health and Human Services (HHS) to harmonize differences between HHS and the U.S. Food and Drug Administration (FDA) regulations governing research with humans. Anticipating that the FDA may update its 2006 centralized IRB guidance, we conducted interviews with 34 stakeholders engaged in FDA-regulated clinical research to identify benefits and challenges of using sIRBs and to gather recommendations for revising the FDA's guidance. The main benefits were consistency and standardization, speed and efficiency, and streamlining and simplification. The main challenges were uncertainty at local institutions, including addressing local context; decreased timeliness of the research review process; variable processes; and insufficient communication. Several recommendations for FDA guidance focused on the local context and communication plans. Findings suggest that the sIRB review process may be gaining efficiency although challenges remain.Advance research directives (ARDs) enable people to document preferences for future research participation in the event of incapacity. This article reports on interviews with 11 dementia researchers in Australia that focused on the content of a prototype ARD and processes for making and using ARDs. Participants agreed that an ARD template should provide information to explain research and the rationale for making a directive, allow the person to nominate trusted individuals to be involved in future decisions, and record the person's general willingness or unwillingness to be involved in research. Providing a list of various research activities elicits preferences and risk tolerances in more detail. Priority groups for ARD implementation include people with a diagnosis involving progressive cognitive impairment and people interested in research. Researchers and health and legal professionals have a role in promoting ARDs. Our findings suggest that, as a voluntary strategy, ARDs could promote appropriate inclusion in research.Clinical studies conducted by the National Institutes of Health's Intramural Research Program (NIH-IRP) provide eligible individuals with access to innovative research treatments that may not otherwise be available. https://www.selleckchem.com/products/srt2104-gsk2245840.html The NIH-IRP's mission is to include all Americans, including American Indians and Alaska Natives, in its clinical research. This study is the first to provide data about inclusion of American Indians/Alaska Natives in NIH-IRP clinical studies. We analyzed data from the more than 1,800 NIH-IRP protocols active in 2014 and 2017. We found that the absolute number of American Indian/Alaska Native enrollees increased between 2014 and 2017 but remained at 1% of all participants, a disproportionately low level. The number of clinical studies that enrolled American Indian/Alaska Native individuals similarly did not change. NIH efforts to expand participation of American Indians/Alaska Natives in clinical studies has often focused on research within their communities or on health needs specific to these groups. Those efforts should expand to include processes and protections for the proportionate and ethical inclusion of American Indians and Alaska Natives who individually enroll in studies that are not specific to American Indians, Alaska Natives, or their tribal nations.Thrombotic microangiopathy (TMA) causes global endothelial damage and multiorgan injury. No study has described reproductive organ involvement in TMA. Our study aimed to characterize testicular involvement in TMA. We reviewed autopsies from four patients who underwent hematopoietic cell transplant (HCT) complicated by TMA. Three patients had striking histologic evidence of TMA, while the fourth had normal testicular histology. This suggests that TMA injures the testicles and may adversely affect fertility. There is now an urgent need for a larger analysis of reproductive organ involvement in TMA.
