BACKGROUND: Reducing maternal mortality and improving maternal health care through increased utilization of postnatal care utilization is a global and local priority. However studies that have been carried out in Ethiopia regarding determinants are limited. So This study aims to assess the magnitude of postnatal care utilization and its determinants in Debre Birhan Town, North Ethiopia. METHODS: A community-based cross-sectional study was conducted from March 1 to April 25, 2015, in Debre Birhan Town...

We identify two orthogonal sources of structural entropy in rattler-free granular systems: affine, involving structural changes that only deform the contact network, and topological, corresponding to different topologies of the contact network. We show that a recently developed connectivity-based granular statistical mechanics separates the two naturally by identifying the structural degrees of freedom with spanning trees on the graph of the contact network. We extend the connectivity-based formalism to include constraints on, and correlations between, degrees of freedom as interactions between branches of the spanning tree...

Vitamin B12 deficiency causes a wide range of hematological, gastrointestinal, psychiatric and neurological disorders. Hematological presentation of cobalamin deficiency ranges from the incidental increase of mean corpuscular volume and neutrophil hypersegmentation to symptoms due to severe anemia, such as angor, dyspnea on exertion, fatigue or symptoms related to congestive heart failure, such as ankle edema, orthopnea and nocturia. Neuropsychiatric symptoms may precede hematologic signs and are represented by myelopathy, neuropathy, dementia and, less often, optic nerve atrophy...

AIMS: We studied the respective added value of the quantitative myocardial blood flow (MBF) and the myocardial flow reserve (MFR) as assessed with (82)Rb positron emission tomography (PET)/CT in predicting major adverse cardiovascular events (MACEs) in patients with suspected myocardial ischaemia. METHODS AND RESULTS: Myocardial perfusion images were analysed semi-quantitatively (SDS, summed difference score) and quantitatively (MBF, MFR) in 351 patients. Follow-up was completed in 335 patients and annualized MACE (cardiac death, myocardial infarction, revascularization, or hospitalization for congestive heart failure or de novo stable angor) rates were analysed with the Kaplan-Meier method in 318 patients after excluding 17 patients with early revascularizations (<60 days)...

Although jammed granular systems are athermal, several thermodynamiclike descriptions have been proposed which make quantitative predictions about the distribution of volume and stress within a system and provide a corresponding temperaturelike variable. We perform experiments with an apparatus designed to generate a large number of independent, jammed, two-dimensional configurations. Each configuration consists of a single layer of photoelastic disks supported by a gentle layer of air. New configurations are generated by cyclically dilating, mixing, and then recompacting the system through a series of boundary displacements...

We discuss the statistical mechanics of granular matter and derive several significant results. First, we show that, contrary to common belief, the volume and stress ensembles are interdependent, necessitating the use of both. We use the combined ensemble to calculate explicitly expectation values of structural and stress-related quantities for two-dimensional systems. We thence demonstrate that structural properties may depend on the angoricity tensor and that stress-based quantities may depend on the compactivity...

This paper illustrates how the tools of equilibrium statistical mechanics can help to describe a far-from-equilibrium problem: the jamming transition in frictionless granular materials. Edwards ideas consist of proposing a statistical ensemble of volume and stress fluctuations through the thermodynamic notion of entropy, compactivity, X, and angoricity, A (two temperature-like variables). We find that Edwards thermodynamics is able to describe the jamming transition (J point) in frictionless packings. Using the ensemble formalism we elucidate the following: (i) We test the combined volume-stress ensemble by comparing the statistical properties of jammed configurations obtained by dynamics with those averaged over the ensemble of minima in the potential energy landscape as a test of ergodicity...

This study reports on a 65-year-old female patient with controlled comorbidity, who was diagnosed with gastrointestinal stromal tumours following regular monitoring of renal cysts. After the surgical treatment, coadjuvant treatment with imatinib was initiated. After a few months, the patient complained of angor and asthenia and the diagnosis of anaemic syndrome was made on the basis of blood test results. We studied the causes of the anaemia (maturation factors and other causes of secondary anaemia) and it led to the diagnosis of vitamin B12 deficiency...

BACKGROUND AND OBJECTIVES: In this paper we analyze the lipid profile of a cohort of patients attended in different tertiary hospitals with acute coronary syndrome (angor pectoris or acute myocardial infarction). PATIENTS AND METHODS: We have analysed different variables of patients with acute coronary syndrome, related with the prevalence and grade of main cardiovascular risk factors, and related with different treatments. We have analysed the lipid profile, and stratified the results according with the status of the first acute coronary event or recurrent coronary event...

We present a framework for analysing the rheology of dense driven granular materials, based on a recent proposal of a stress-based ensemble. In this ensemble, fluctuations in a granular system near jamming are controlled by a temperature-like parameter, the angoricity, which is conjugate to the stress of the system. In this paper, we develop a model for slowly driven granular materials based on the stress ensemble and the idea of a landscape in stress space. The idea of an activated process driven by the angoricity has been shown by Behringer et al...

We discuss the microstates of compressed granular matter in terms of two independent ensembles: one of volumes and another of boundary force moments. The former has been described in the literature and gives rise to the concept of compactivity: a scalar quantity that is the analogue of temperature in thermal systems. The latter ensemble gives rise to another analogue of the temperature: an angoricity tensor. We discuss averages under either of the ensembles and their relevance to experimental measurements. We also chart the transition from the microcanoncial to a canonical description for granular materials and show that one consequence of the traditional treatment is that the well-known exponential distribution of forces in granular systems subject to external forces is an immediate consequence of the canonical distribution, just as in the microcanonical description E = H leads to exp (-H/kT)...

BACKGROUND: Obesity is an independent risk factor for cardiovascular disease, especially in its morbid form. Bariatric surgery is an effective therapeutic option for sustained weight loss. However, there is no consensus in these cases regarding the performance of functional tests for preoperative evaluations. The aim of the present study was to analyze clinical, electrocardiographic, and hemodynamic response variables using a conventional exercise test on individuals with morbid obesity in comparison to overweight individuals...

Takotsubo is a reversible cardiomyopathy, often triggered by a stressful event. It combines clinical features mimicking a myocardial infarction, transient apical ballooning of the left ventricle, normal coronary arteries and a small rise in troponin level. There is a striking female predominance with mean age ranging from 65 to 76 years among series. Preceding stressful event is documented in 50 to 100% of patients. The most common clinical presentation is an angor-like chest pain with ST-segment elevation on the electrocardiogram (70%)...
