Although the female predominance of autoimmune diseases is not completely understood, sex hormones are thought to play a role. Attention to lifelong reproductive health is especially important for women with autoimmune disorders. Many of these women require long-term immunosuppressive therapy that may affect their ability to clear infections, including viruses, and may alter natural tumor surveillance mechanisms.

Inhibitor of DNA binding (Id) proteins, including Id1-4, are transcriptional regulators involved in promoting cell proliferation and survival in various cell types. Although upregulation of Id proteins is associated with a broad spectrum of tumors, recent studies have identified that Id3 plays a tumor-suppressor role in the development of Burkitt's lymphoma in humans and hepatosplenic T cell lymphomas in mice. In this article, we report rapid lymphoma development in / double-knockout mice that is caused by unchecked expansion of invariant NKT (iNKT) cells or a unique subset of innate-like CD1d-independent T cells.

OBJECTIVE The deep and difficult-to-reach location of basilar apex aneurysms, along with their location near critical adjacent perforating arteries, has rendered the perception that microsurgical treatment of these aneurysms is risky. As a result, these aneurysms are considered more suitable for treatment by endovascular intervention. The authors attempt to compare the immediate and long-term outcomes of microsurgery versus endovascular therapy for this aneurysm subtype.

Importance: There is a significant need to find biomarkers of response to radiotherapy and cetuximab in locally advanced head and neck squamous cell carcinoma (HNSCC) and biomarkers that predict altered immunity, thereby enabling personalized treatment.

Objectives: To examine whether the Kirsten rat sarcoma viral oncogene homolog (KRAS)-variant, a germline mutation in a microRNA-binding site in KRAS, is a predictive biomarker of cetuximab response and altered immunity in the setting of radiotherapy and cisplatin treatment and to evaluate the interaction of the KRAS-variant with p16 status and blood-based transforming growth factor β1 (TGF-β1).

Design, Setting, And Participants: A total of 891 patients with advanced HNSCC from a phase 3 trial of cisplatin plus radiotherapy with or without cetuximab (NRG Oncology RTOG 0522) were included in this study, and 413 patients with available samples were genotyped for the KRAS-variant.

JCL roundtable: Managing lipid disorders in young women.

J Clin Lipidol

October 2017

Department of Obstetrics and Gynecology, Oklahoma University Health Sciences Center, Oklahoma City, OK, USA.

The roundtable discussion in this issue will focus on the problems faced by young women with lipid disorders. This is often the source of confusion for the patient and physician because the myth continues that young women do not have complications of atherosclerosis as a result of elevated blood cholesterol. The essential role of women in bearing children during the early years of adulthood also produces difficult decisions because the mother and fetus are usually experiencing similar exposure to therapeutic regimens.

Tumor treating fields (TTFields) are an integral treatment modality in the management of glioblastoma and extend overall survival when combined with maintenance temozolomide in newly diagnosed patients. Complexities exist regarding correct selection of imaging sequences with which to perform TTFields treatment planning. Guidelines are warranted first, to facilitate treatment planning standardization across medical disciplines and institutions, to ensure optimal TTFields delivery to the tumor and peritumoral brain zone while maximizing patient safety, and also to mitigate the risk of premature cessation of a potentially beneficial treatment.

Cancer cell metabolism differs significantly from the metabolism of non-transformed cells. This altered metabolic reprogramming mediates changes in the uptake and use of nutrients that permit high rates of proliferation, growth, and survival. The androgen receptor (AR) plays an essential role in the establishment and progression of prostate cancer (PCa), and in the metabolic adaptation that takes place during this progression.

Environmental risk factors for inflammatory bowel diseases: Evidence based literature review.

World J Gastroenterol

July 2016

Ayokunle T Abegunde, Tauseef Ali, Section of Digestive Diseases and Nutrition, Department of Medicine, Oklahoma University Health Sciences Center, Oklahoma City, OK 73104, United States.

Aim: Advances in genetics and immunology have contributed to the current understanding of the pathogenesis of inflammatory bowel diseases (IBD).

Methods: The current opinion on the pathogenesis of IBD suggests that genetically susceptible individuals develop intolerance to dysregulated gut microflora (dysbiosis) and chronic inflammation develops as a result of environmental insults. Environmental exposures are innumerable with varying effects during the life course of individuals with IBD.

Probucol normalizes cholesteryl ester transfer in type 2 diabetes.

Diabetes Res Clin Pract

June 2016

Department of Medicine, University of Illinois at Chicago College of Medicine, 909 S. Wolcott, Chicago, IL 60612, United States; Department of Biochemistry, University of Illinois at Chicago College of Medicine, 909 S. Wolcott, Chicago, IL 60612, United States.

Aims: Accelerated cholesteryl ester transfer (CET) protein (CETP) activity is believed to promote macrovascular disease in patients with type 2 diabetes (T2D) by increasing the cholesterol burden of the apoB - containing triglyceride-rich lipoprotein (TGRLP) CE acceptors and promoting small dense LDL formation. While previous studies have shown that this same abnormality is present in patients with type 1 diabetes (T1D) and was normalized by the anti-oxidant drug probucol, its effects on CET in T2D are unknown.

Patients And Methods: The net mass transfer of CE from HDL to the apoB lipoproteins (VLDL+LDL) was studied in intact plasma from seven T2D patients before and two months after treatment with probucol (1g/day).

Recent clinical trials have challenged the concept that aggressive full feeding as close to goal requirements as possible is necessary in the first week following admission to the intensive care unit. While the data suggesting that permissive underfeeding is better than full feeds are methodologically flawed, other data do indicate that in certain well-defined patient populations, outcomes may be similar. The most important issues for clinicians in determining optimal nutrition therapy for critically ill patients are to carefully determine nutrition risk and differentiate nutrition from nonnutrition benefits of early enteral feeding.
