Clinicians, including hematologists,are more frequently encountering transgender individuals in practice; however,most lack training on the management and complications of transgender medicine. Hormonal therapy forms the backbone of medical interventions for patients undergoing gender transition. While supplementing an individual's intrinsic sex hormone is associated with a variety of hematologic complications including increased rates of venous thrombosis, cardiovascular events, erthyrocytosis, and malignancy, the risks of supplementing with opposing sex hormones are not well understood...

Global cancer burden increased to 14.1 million new cases in 2012; and breast cancer is the most common cancer in women worldwide, with nearly 1.7 million new cases diagnosed in 2012. Curcumin is the major bioactive ingredient extracted from the rhizome of the plant Curcuma longa (turmeric). Paclitaxel is a microtubule-stabilizing agent originally isolated from the bark of Taxus brevifolia. Curcumin and paclitaxel were evaluated with two human breast cancer cell lines as the luminal MCF-7 and the basal-like MDA-MB-231 that are either positive or negative for hormonal receptors estrogen receptor, progesterone receptor and HER2, respectively...

Fear extinction is the laboratory basis of exposure therapy for anxiety disorders. Recent findings have revealed that estradiol is necessary to the consolidation of extinction memories in females. These findings are based on studies conducted using virgin rats and young women whose reproductive history is unknown. We hypothesized that motherhood, which results in extensive endocrinological, neurobiological and behavioral changes, may lead to alterations in fear extinction in females. We used a cross-species translational approach to investigate the impact of reproductive experience on fear extinction and fear relapse in female rats (n=116) and women (n=64)...

Tumor infiltrating lymphocytes (TIL) play an essential role in mediating response to chemotherapy and improving clinical outcomes in all subtypes of breast cancer. Triple negative breast cancers (TN) are most likely to have tumors with >50 % lymphocytic infiltrate, termed lymphocyte predominant breast cancer, and derive the greatest survival benefit from each 10 % increase in TIL. The majority of HER2(+) breast cancers have similar level of immune infiltrate as TN breast cancer yet the presence of TILs has not shown the same survival benefit...

BACKGROUND: Multiple causes outside the spine can mimic spinal back pain. Endometriosis is an important gynecological disorder, which commonly affects the lower region of the female pelvis and less frequently the spine and soft tissues. The lumbosacral trunk is vulnerable to pressure from any abdominal mass originating from the uterus and the ovaries. Therefore symptoms of endometriosis include severe reoccurring pain in the pelvic area as well as lower back and abdominal pain. CASE DESCRIPTION: We report on a 39 year old gymnast with cyclic sciatica and back pain, whose initial presentation initially led to a spinal fusion at L4/5 and L5/S1, but that procedure did not change her symptoms...

Current dogma suggests patients with advanced systolic heart failure have an irreversible depression in myocardial contractility. Recent experience with improved ventricular function during continuous flow ventricular assist devices used as destination therapy would suggest otherwise. Herein, cellular and molecular signaling involved in reversing depressed myocardial contractility would be addressed. This includes cardiomyocyte thyroid hormone signaling responsible for the reexpression of fetal gene program that preserves cell efficiency (work and energy consumed) and the rescue of an endogenous population of atrophic myocytes bordering on microdomains of fibrosis to improve contractile mass...

BACKGROUND: There is controversy over the prevalence of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) and cerebral or renal salt wasting (RSW), 2 syndromes with identical common clinical and laboratory parameters but different therapies. The traditional approach to the hyponatremic patient relies on volume assessment, but there are limitations to this method. METHODS: We used an algorithm that relies on fractional excretion of urate (FEurate) to evaluate patients with hyponatremia and present 4 illustrative cases...

During acute exercise, the concentration of oxidized HDL lipids (ox-HDL) is reported to increase suggesting that HDL may function in decreasing the concentration of oxidized LDL lipids. However, the effect of exercise intervention on the lipid peroxide transport function of HDL is unknown. A randomized controlled trial with sedentary women (N = 161), aged 43-63, with no current use of hormone therapy, were randomized into a 6-month (mo) exercise group and a control group. During the 6-mo intervention, the concentration of ox-HDL increased in the exercise group by 5% and decreased in the control group by 2% (p = 0...

Breast cancer is approximately 100 times less common among men. Estrogen-related receptor α was detected in human prostate cancer tissue, and androgen receptors are expressed in both normal and malignant breast tissue. Thus, prostate cancer hormonal therapy may increase breast cancer risk. A 67-year-old man with prostate cancer history presented with rising prostate-specific antigen level. F-Fluorocholine PET/CT showed intense uptake in his right breast and moderate uptake in right axillary lymph node. Complementary F-FDG PET/CT demonstrated more intense tracer uptakes in both the right breast and axillary lymph node...

Triple-negative breast cancer (TNBC), in which cells lack expression of the estrogen receptor (ER), the progesterone receptor (PR) and the ERBB2 (also known as HER2) receptor, is the breast cancer subtype with the poorest outcome. No targeted therapy is available against this subtype of cancer owing to a lack of validated molecular targets. We previously reported that signaling involving MYC-an essential, pleiotropic transcription factor that regulates the expression of hundreds of genes-is disproportionally higher in triple-negative (TN) tumors than in receptor-positive (RP) tumors...

BACKGROUND: LIM and SH3 domain protein 1 (LASP1) has been implicated in several human malignancies and has been shown to predict PSA recurrence in prostate cancer. However, the anti-tumor effect of LASP1 knockdown and the association between LASP1 and the androgen receptor (AR) remains unclear. The aim of this study is to clarify the significance of LASP1 as a target for prostate cancer, and to test the effect of silencing LASP1 in vivo using antisense oligonucleotides (ASO). METHODS: A tissue microarray (TMA) was performed to characterize the differences in LASP1 expression in prostate cancer treated after hormone deprivation therapy...
