OBJECTIVE: To identify risk factors for maternal morbidity after previable prelabor rupture of membranes (PROM). METHODS: We conducted a case-control study of singleton and twin pregnancies complicated by previable PROM (14.0-22.9 weeks of gestation) at a single tertiary care referral institution, 2000-2015. Pregnancies complicated by fetal anomalies, previable PROM within 2 weeks of chorionic villus sampling or amniocentesis, and those with contraindications to expectant management (eg, chorioamnionitis) were excluded...

Significance Redox signaling is one of the key elements involved in cardiovascular diseases. Two important molecules are the transcription factor Nuclear factor erythroid 2-related factor 2 (Nrf2) and the oxidoreductase Thioredoxin-1 (Trx-1). Recent Advances During the last years, a lot of studies investigated Nrf2 and Trx-1 as protective proteins in cardiovascular disorders. Moreover, post-translational modifications of those molecules were identified which play an important role in the cardiovascular system...

BACKGROUND AND PURPOSE: Heart failure with preserved ejection fraction (HFpEF) is a systemic syndrome driven by co-morbidities and its pathophysiology is poorly understood. Several studies suggesting that dipeptidyl peptidase 4 (DPP4) might be involved in the pathophysiology of heart failure prompted experimental and clinical investigations of DPP4 inhibitors on cardiovascular system. The aim of our study was to determine whether DPP4 inhibitor sitagliptin (SITA) affects the progression of HFpEF independently from the effects on glycaemia...

BACKGROUND/PURPOSE: Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. METHODS/MATERIALS: A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed...

We have developed a novel chromatographic analytical method for the simultaneous quantitation of collagen crosslinks. Seven non-derivatised crosslinks could be separated on a Cogent Diamond Hydride HPLC column using either isocratic or gradient conditions then detected by mass spectrometry. The total run time was less than 10min which is significantly shorter than that previously reported. This is the first method in which histidinohydroxylysinonorleucine (HHL) and histidinohydroxymero-desmosine (HHMD) were separated and identified by mass spectrometry without the need for pre- or post-column derivatization...

Cannabinoid receptors (CBR), including CB1 and CB2 have been therapeutic targets for a number of conditions. Recently, splice variants of the CB1R have been identified in humans. The isoforms differ in their N-terminus sequence and pharmacological activity relative to the CB1R, as a result, the differentiation between the CB1 receptor and its isoform is required. As a result, a selected reaction monitoring mass spectrometry (SRM-MS) method was developed for the quantitation of CB1 and the CB1b isoform in CHO cells transduced with CB1 and CB1b...

Cyclic Vomiting Syndrome (CVS) has been linked to episodic migraine, yet little is known about the precise brain-based mechanisms underpinning CVS, and whether these associated conditions share similar pathophysiology. We investigated the functional integrity of salience (SLN) and sensorimotor (SMN) intrinsic connectivity networks in CVS, migraine and healthy controls using brain functional Magnetic Resonance Imaging. CVS, relative to both migraine and controls, showed increased SLN connectivity to middle/posterior insula, a key brain region for nausea and viscerosensory processing...

Metformin, a synthetic biguanide, is currently one of the most frequently recommended medications for type 2 diabetes treatment around the world. In this review, we present the latest discoveries in the pharmacokinetics of metformin, especially the role of transporters (e.g. Organic Cation Transporters OCTs, Multidrug and Toxin Extrusion transporters MATE) in oral absorption, distribution, elimination and biochemical effects of metformin in humans. We also review the associations between genetic variations of metformin transporters, their pharmacokinetics and drug efficacy or drug responses...

BACKGROUND: Computed tomographic (CT) cardiac angiography is of increasing value in several areas of patient management in cardiology. We assessed the ability of CT cardiac angiography to effectively 'rule out' severe coronary stenoses in patients presenting with 'atypical' symptoms and/or an equivocal stress test, which offers a new approach to the management of coronary artery disease. We also examined the use of the CT calcium score test in cardiovascular (CVS) risk assessment. METHODS: From a large single centre (Mercy Hospital) in Auckland, using a prospectively acquired, comprehensive database, we audited the entire eight-year experience of 5,169 patients (7/8/06 to 31/1/14) who underwent 5,237 64-slice computed tomographic (CT) cardiac angiogram or CT calcium score tests (GE Lightspeed scanner)...

Hypoglycemia is the major barrier for optimal glycemic control in patients on maintenance insulin therapy. It is widely known that good glycemic control leads to prevention of or delay in the development of microvascular complications, and can reduce macrovascular events. It is thought that hypoglycemia may predispose patients to cognitive deterioration and may negatively affect the cardiovascular system. Hypoglycemia per se can contribute to a blunted counterregulatory response and disabling hypoglycemia, while hypoglycemia avoidance restores normal response to low blood glucose levels...

Continuous noninvasive measurement of vital bio-signs, such as cardiopulmonary parameters, is an important tool in the evaluation process of the patient's physiological condition and in the health monitoring of the patient. On the demand of new enabling technologies, some works have been done in continuous monitoring of blood pressure and pulse wave velocity. In this paper, we introduce further application of a novel technique for remote noncontact blood pulse wave velocity and pressure measurement based on tracking the temporal changes of reflected secondary speckle patterns produced in human skin when illuminated by a laser beam...

Despite the combined antiretroviral therapy has improved the length and quality of life of HIV infected patients, the survival of these patients is always decreased compared with the general population. This is the consequence of non-infectious illnesses including cardio vascular diseases. In fact large studies have indicated an increased risk of coronary atherosclerotic disease, myocardial infarction even in HIV patients on cART. In HIV infected patients several factors may contribute to the pathogenesis of cardiovascular problems: life-style, metabolic parameters, genetic predisposition, viral factors, immune activation, chronic inflammation and side effects of antiretroviral therapy...

BACKGROUND: Nematodes play a key role in soil processes with alterations in the nematode community structure having the potential to considerably influence ecosystem functioning. As a result fluctuations in nematode diversity and/or community structure can be gauged as a 'barometer' of a soil's functional biodiversity. However, a deficit exists in regards to baseline knowledge and on the impact of specific GM crops on soil nematode populations and in particular in regard to the impact of GM potatoes on the diversity of nematode populations in the rhizosphere...

Antineoplastic agents affect the cardiovascular system, and the incidence of cardiotoxicity is continuously growing in patients with hematologic malignancies and treated with antineoplastic therapy. Cardio-oncology is a quite young discipline, designed for diagnosis, prevention and treatment of cardiovascular complications of anticancer agents. Nowadays, with the current treatments and an accurate pharmacological control of comorbidities present at the time of the oncological diagnosis, early clinical events are infrequent, and it seems indeed that cardiotoxicity could emerge as time and years go by, after therapies completion...
