Aims: Acute myocardial infarction (AMI) is a significant cardiovascular complication following non-cardiac surgery. We sought to evaluate national trends in perioperative AMI, its management, and outcomes. Methods and results: Patients who underwent non-cardiac surgery from 2005 to 2013 were identified using the United States National Inpatient Sample. Perioperative AMI was evaluated over time. Propensity score matching was used to compile a cohort of AMI patients managed invasively (defined as cardiac catheterization or coronary revascularization) vs...

Invasive species are one among many threats to biodiversity. Brazil has been spared, generically, of several destructive invasive species. Reports of invasive snakes' populations are nonexistent, but the illegal pet trade might change this scenario. Despite the Brazilian laws forbid to import most animals, illegal trade is frequently observed and propagules are found in the wild. The high species richness within Brazilian biomes and accelerated fragmentation of natural reserves are a critical factors facilitating successful invasion...

PURPOSE: Breast conserving surgery (BCS) has become the preferred surgical option for the management of patients with nonmetastatic breast cancer in high-income countries. However, little is known about the distribution and determinants of BCS in low-and middle-income countries, especially those with high HIV prevalence. METHODS: We compared demographic and clinical characteristics of female patients who received BCS and those who received total mastectomy (TM) for nonmetastatic invasive carcinoma of the breast in Soweto, South Africa, 2009-2011...

BACKGROUND: Women with ductal carcinoma in situ (DCIS) are increasingly choosing bilateral mastectomy. We sought to quantify rates of contralateral breast cancer (CBC) and ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) for DCIS, and to compare risk factors for CBC and IBTR. METHODS: From 1978 to 2011, DCIS patients undergoing BCS with a contralateral breast at risk were identified from a prospectively maintained database. The association of clinicopathologic and treatment factors with CBC and IBTR were evaluated using Kaplan-Meier analysis, multivariable Cox regression, and competing risk regression (CRR)...

BACKGROUND: Strategies to reduce the likelihood of axillary lymph node dissection (ALND) include application of Z0011 or use of neoadjuvant chemotherapy (NAC). Indications for ALND differ by treatment plan, and nodal pathologic complete response rates after NAC vary by tumor subtype. This study compared ALND rates for cT1-2N0 tumors treated with upfront surgery versus those treated with NAC. METHODS: The ALND rates for cT1-2N0 breast cancer patients were compared by tumor subtype among women undergoing upfront surgery to NAC...

The assessment of ischemia through myocardial perfusion imaging (MPI) is widely accepted as an index step in the diagnostic evaluation of stable ischemic heart disease (SIHD). Numerous observational studies have characterized the prognostic significance of ischemia extent and severity. However, the role of ischemia in directing downstream SIHD care including coronary revascularization has remained elusive as reductions in ischemic burden have not translated to improved clinical outcomes in randomized trials...

BACKGROUND/PURPOSE: The 21-gene recurrence score (RS) assay evaluates the likelihood of distant recurrence and benefit of chemotherapy in lymph node-negative, estrogen receptor (ER)-positive, HER2-negative breast cancer patients. The RS categories are associated with the risk of locoregional recurrence (LRR) in some, but not all studies. METHODS: We reviewed the institutional database to identify consecutive female patients with node-negative, ER+/HER2- breast carcinoma tested for the 21-gene RS assay and treated at our center from 2008 to 2013...

PURPOSE: The completion of the vescico-urethral anastomosis (VUA) represents the most critical step of laparoscopic radical prostatectomy (LRP), and it can often discourage the use of minimally invasive surgery in less experienced laparoscopic surgeons. The aim of this paper is to evaluate the usefulness of a new robotic needle driver named Dextérité in performing the VUA after LRP. MATERIALS AND METHODS: This prospective randomized clinical study enrolled 40 consecutive patients eligible for LRP, which were randomized into four groups: group A, patients undergoing LRP done by an expert surgeon; group B, patients undergoing robotic-assisted radical prostatectomy (RARP) performed by the same expert surgeon; group C, patients undergoing LRP performed by a young surgeon at the beginning of the learning curve; group D, patients undergoing LRP performed by another young surgeon at the beginning of the learning curve with the aid of Dextérité needle driver for completion of the VUA...

BACKGROUNDS: Chronic intestinal pseudo-obstruction (CIPO) is an intractable rare digestive disease manifesting persistent small bowel distension without any mechanical cause. Intestinal decompression is a key treatment, but conventional method including a trans-nasal small intestinal tube is invasive and painful. Therefore, a less invasive and tolerable new decompression method is urgently desired. We conducted a pilot study and assessed the efficacy and safety of percutaneous endoscopic gastro-jejunostomy (PEG-J) decompression therapy in CIPO patients...

Recognizing the potential value of steroid hormone measurements to augment non-invasive genetic sampling, we developed procedures based on enzyme-linked immunoassays to quantify reproductive steroid hormone concentrations in brown bear (Ursus arctos) hair. Then, using 94 hair samples collected from eight captive adult bears over a 2-year period, we evaluated (i) associations between hair concentrations of testosterone, progesterone, estradiol and cortisol; (ii) the effect of collecting by shaving vs. plucking; and (iii) the utility of reproductive hormone profiles to differentiate sex and reproductive state...

BACKGROUND: The benefit of neoadjuvant chemotherapy (NAC) in patients with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancers and in invasive lobular carcinoma (ILC) is uncertain due to the low rates of pathologic complete response (pCR). OBJECTIVE: The aim of this study was to determine if pathologic features can identify subsets likely to benefit from NAC. METHODS: Patients with stage I-III ER+, HER2- breast cancer receiving NAC were retrospectively reviewed...

Musashi-1, an evolutionally conserved RNA-binding protein, has been implicated in the promotion of pathological stem cell proliferation, including tumorigenesis. The objective of the present study was to evaluate the expression of Musashi-1 protein and its implications in the progression and prognosis of gastric cancer. The expression level of Musashi-1 protein in gastric cancer was determined by western blotting and immunohistochemistry, and compared with the clinicopathological parameters. The present study revealed that the expression level of Musashi-1 protein in gastric cancer was significantly upregulated and correlated with the tumor size, tumor-node-metastasis (TNM) stage, Lauren classification, depth of invasion, vessel invasion, lymph node metastasis and distant metastasis...

Homeobox (HOX) genes are conserved transcription factors which determine the anterior-posterior body axis patterning. HOXD8 is a member of HOX genes deregulated in several tumors such as lung carcinoma, neuroblastoma, glioma and colorectal cancer (CRC) in a context-dependent manner. In CRC, HOXD8 is downregulated in cancer tissues and metastatic foci as compared to normal tissues. Whether HOXD8 acts as a tumor suppressor of malignant progression and metastasis is still unclear. Also, the underlying mechanism of its function including the downstream targets is totally unknown...

RANDOMIZED CONTROLLED TRIAL
Sang-Eun Lee, Fay Y Lin, Yao Lu, Hyuk-Jae Chang, James K Min
Although coronary computed tomography angiography (CCTA) has shown promise as a "gatekeeper" to invasive coronary angiography (ICA) in longitudinal cohort studies, it remains unknown whether the strategy of selective ICA by initial performance of CCTA is either safe or effective when compared with a direct ICA strategy in patients with an American Heart Association (AHA)/American College of Cardiology (ACC) guideline-directed indication for ICA. OBJECTIVES: The CONSERVE trial is a prospective randomized multicenter trial to determine the clinical effectiveness of "selective catheterization" vs "direct catheterization" strategies for stable patients with suspected but without known coronary artery disease, who meet AHA/ACC guideline indication for ICA...

This paper presents European expert consensus guidelines on the management of severe tooth wear. It focuses on the definition of physiological vs pathological tooth wear and recommends diagnosis, prevention, counseling, and monitoring aimed at elucidating the etiology, nature, rate and means of controlling pathological tooth wear. Management decisions are multifactorial, depending principally on the severity and effects of the wear and the wishes of the patient. Restorative intervention is typically best delayed as long as possible...

BACKGROUND: An early invasive strategy for patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) has been recommended. However, patients at greater risk including the elderly are more often managed conservatively. We aimed to elucidate contemporary practice and outcomes of patients with NSTE-ACS who were referred to our hospital located in Kitakyushu City, one of the most aging metropolises in Japan. METHODS: A total of 270 consecutive NSTE-ACS patients hospitalized between January 2012 and December 2014 were retrospectively studied...
