AIMS: Although the role of phosphorylation of oestrogen receptor (ER) at serines 118 (p-S118) and 167 (p-S167) have been studied, the relationship between p-S118, p-S167 and the tumour microenvironment in ER-positive primary operable ductal breast cancers have not been investigated. The aims of this study are to investigate (1) the relationship between p-S118/p-S167 and the tumour microenvironment and (2) the effect of p-S118/167 on survival and recurrence in ER-positive primary operable ductal breast cancers...

OBJECTIVE: Telomere shortening occurs as an early event in pancreatic tumorigenesis, and genetic variants at the telomerase reverse transcriptase (TERT) gene region have been associated with pancreatic cancer risk. However, it is unknown whether prediagnostic leucocyte telomere length is associated with subsequent risk of pancreatic cancer. DESIGN: We measured prediagnostic leucocyte telomere length in 386 pancreatic cancer cases and 896 matched controls from five prospective US cohorts...

BACKGROUND: Less-invasive techniques have previously been described for mitral and aortic valve operations; however, few studies have examined their benefit for aortic root and ascending aorta reconstruction. Using propensity matching, we compared outcomes of patients undergoing proximal aortic operations through a J incision compared with full sternotomy. METHODS: From January 1995 to January 2014, 8,533 patients underwent proximal aortic operations at Cleveland Clinic...

BACKGROUND: Since 2005, the Lung Allocation Score (LAS) has prioritized patient benefit and post-transplant survival, reducing waitlist to transplant time to <200 days and decreasing mortality on the waitlist. A current challenge is the wait for the waitlist-the time between the patient's transplant-eligible diagnosis and waitlist registration. METHODS: We investigated whether sociodemographic (age, sex, race, insurance, marital status, median household income) and clinical (forced expiratory volume in 1 second [FEV1] percent of predicted, body mass index, depression/anxiety, alcohol/substance misuse, absolute/relative contraindications) factors influenced referral and waitlist registration...

Sutureless aortic bioprostheses (SAB) are increasingly being used to provide shorter cross-clamp time. Valve-in-valve transcatheter aortic valve replacement (VIV-A) is shown to be effective and safe in the vast majority of patients with degenerated bioprosthetics, yet its' use in SAB failure is infrequent. We present a case of balloon-expandable VIV-A in an 80-year-old woman who suffered severe symptomatic aortic regurgitation in a failed Perceval S 21-mm valve. Computed tomography scan demonstrated a deformed valve...

Transcatheter aortic valve replacement (TAVR) is conventionally performed under general anesthesia (GA) allowing intraoperative transoesophageal echocardiogram imaging. We present our experience in patients having the procedure under local anesthesia (LA), who were subsequently transferred to a low dependency unit postprocedure, to assess safety and length of hospital stay. We retrospectively assessed all the transfemoral TAVR procedures conducted at our center from January 03, 2011. Of 216 patients, 145 had the procedure under GA and 71 under LA...

Recent international efforts have led to proposals for modified carcinogenicity testing paradigms based on data from shorter-term studies. The main goal of the current study was to evaluate the negative predictive value (NPV) of short-term toxicity indicators on carcinogenicity study outcomes and cancer classifications for chemicals previously reviewed by the U.S. Environmental Protection Agency (EPA). Pathology data were analyzed from over 900 acceptable 2-sex guideline subchronic (3-month) and carcinogenicity studies in the U...

: This is a cross-sectional study to assess differences in bone quality in young Asian and Caucasian (n = 30/group) men between 25 and 35 years. We found that Asians had smaller bones, thicker and denser cortices, and more plate-like trabeculae, but stiffness did not differ between groups. INTRODUCTION: We conducted a cross-sectional study to assess differences in bone quality in young Asian and Caucasian (n = 30/group) men between 25 and 35 years. METHODS: We measured bone mineral density (BMD) at the spine, total hip (TH), femoral neck (FN), and forearm by dual energy X-ray absorptiometry (DXA), and bone geometry, density, microarchitecture, and mechanical competence at the radius and tibia by high-resolution peripheral quantitative computed tomography (HR-pQCT) with application of individual trabecula segmentation (ITS) and trabecular and whole bone finite element analysis (FEA)...

Neonatal abstinence syndrome (NAS) affects 3.39 in every 1,000 live births. A literature review was conducted to determine the varying types of nonpharmacologic management being used currently and its effect on the treatment of NAS symptoms. Fourteen articles were found that used nonpharmacologic management in the treatment of NAS. Therapies included breastfeeding, positioning, rooming-in, acupuncture/acupressure, and beds. Each of the nonpharmacologic therapies in these articles, with the exception of rocking beds, was shown to have a positive effect on the newborn with NAS...

Anatomical tract tracing methods are the gold standard for estimating the weight of axonal connectivity between a pair of pre-defined brain regions. Large studies, comprising hundreds of experiments, have become feasible by automated methods. However, this comes at the cost of positive-mean noise making it difficult to detect weak connections, which are of particular interest as recent high resolution tract-tracing studies of the macaque have identified many more weak connections, adding up to greater connection density of cortical networks, than previously recognized...

Short or damaged telomeres have been implicated in degenerative conditions. We hypothesized that analysis of telomere length (TL) in human T-cell lymphotropic virus (HTLV) infection and HTLV-associated neuropathy might provide clues to the etiology of HTLV-associated disease and viral dynamics. A subset of 45 human T-cell lymphotropic virus type 1 (HTLV-1), 45 human T-cell lymphotropic virus type 2 (HTLV-2), and 45 seronegative subjects was selected from the larger HTLV Outcomes Study (HOST) cohort, matched on age, sex and race/ethnicity...
