The objective of this report was to summarize current knowledge of CC, squamous intraepithelial lesions, and human papillomavirus (HPV) infection in non-HIV immunocompromised women to determine best practices for CC surveillance in this population and provide recommendations for screening. We evaluated those with solid organ transplant, hematopoietic stem cell transplant, and a number of autoimmune diseases. A panel of health care professionals involved in CC research and care was assembled to review and discuss existing literature on the subject and come to conclusions about screening based on available evidence and expe...

Authors: Bewersdorf JP, Stahl M, Zeidan AM Abstract INTRODUCTION: Immune system evasion is essential for tumor cell survival and is mediated by the immunosuppressive tumor microenvironment and the activation of inhibitory immune checkpoints. While immune checkpoint-based therapy yielded impressive results in several advanced solid malignancies such as melanoma and non-small cell lung cancer, its role in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) is still evolving. Areas covered: Here we review the immunology in the tumor microenvironment in the bone marrow and discuss the current preclinical an...

This study provides a possible reason why genes carrying health risks have persisted in human populations. The second found evidence for multiple variants in genes related to ageing that exhibited antagonistic pleiotropic effects. They found higher risk allele frequencies with large effect sizes for late-onset diseases (relative to early-onset diseases) and an excess of variants with antagonistic effects expressed through early and late life diseases. There also exists other recent tangible evidence of antagonistic pleiotropy in specific human genes. The SPATA31 gene has been found under strong positive genomic sele...

We report the case of a patient with ALK translocated ALCL with CNS involvement who developed debilitating neuropathy after chemotherapy and was treated with alectinib at relapse. The patient had a complete response after 6 weeks which has continued for 6 months allowing him to undergo an allogeneic stem cell transplant. To our knowledge, this is the first published case report of a patient with ALCL successfully treated with alectinib.

This is the organoid era of tissue engineering. Researchers are making earnest progress in establishing the recipes that allow cells to be grown into small, functional tissue sections. They lack a network of capillaries, however, so must be no more than a millimeter or so in thickness in order for nutrients to perfuse sufficiently through the tissue to support all of its cells. Every organ, every tissue has a significantly different recipe, but it is usually something that can be derived from an examination of the biochemistry of embryonic growth, with enough time and funding. Given the large number of different tissues ve...

In the present study, we have provided convincing evidence in vitro and in vivo demonstrating thatNr5a2 can induce lung cancer stem cells (CSC) properties and promote tumorigenesis and progression through transcriptional up ‐regulation of Nanog. AbstractLung cancer has the highest mortality rate due to late diagnosis and high incidence of metastasis. Cancer stem cells (CSCs) are a subgroup of cancer cells with self ‐renewal capability similar to that of normal stem cells (NSCs). While CSCs may play an important role in cancer progression, mechanisms underlying CSC self‐renewal and the relationship between self‐rene...

Graft-versus-host disease (GVHD) of the lung, also known as bronchiolitis obliterans syndrome (BOS), is associated with high mortality, but treatment with the combination of fluticasone, azithromycin, and montelukast (FAM) stabilizes lung function in the majority of patients. Recently, a randomized controlled trial evaluating azithromycin given at the time of conditioning for GVHD prevention was closed prematurely due to an increased risk of cancer relapse in azithromycin recipients. We evaluated whether exposure to azithromycin after allogeneic hematopoietic cell transplantation (allo-HCT), primarily for treatment of BOS,...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...

In this study, scientists screened cells from old animals to identify any RBPs that change upon aging. The screening showed that one particular protein, Pumilio2 (PUM2), was highly induced in old animals. PUM2 binds mRNA molecules containing specific recognition sites. Upon its binding, PUM2 represses the translation of the target mRNAs into proteins. Using a systems genetics approach, the researchers then identified a new mRNA target that PUM2 binds. The mRNA encodes for a protein called Mitochondrial Fission Factor (MFF), and is a pivotal regulator of mitochondrial fission - a process by which mitochondria break u...
