BACKGROUND Coronary artery calcifications (CACs) are associated with coronary atherosclerosis and cardiovascular (CV) events. In "non-cardiovascular" settings, CACs can be easily detected on chest multi-detector computed tomography (MDCT). Their evaluation may help to better stratify CV risk in the general population, especially for primary prevention. AIMS We retrospectively evaluated the relationship between CAC distribution and CV risk, determined by Framingham Risk Score (FRS), in a cohort of patients who underwent chest MDCT performed for several clinical indications...

BACKGROUND: Tardive dyskinesia (TD) is a disabling movement disorder associated with the prolonged use of antipsychotic medication. Several strategies have been examined in the treatment of TD. Currently, however, there is no clear evidence of the effectiveness of these drugs in TD and they have been associated with many side effects. One particular strategy would be to use pharmaceutical agents which are known to influence the catecholaminergic system at various junctures. OBJECTIVES: 1...

REVIEW
Hanna Bergman, Karla Soares-Weiser
BACKGROUND: Antipsychotic (neuroleptic) medication is used extensively to treat people with serious mental illnesses. However, it is associated with a wide range of adverse effects, including movement disorders. Because of this, many people treated with antipsychotic medication also receive anticholinergic drugs in order to reduce some of the associated movement side-effects. However, there is also a suggestion from animal experiments that the chronic administration of anticholinergics could cause tardive dyskinesia...

To investigate the effect of breath-holding on left-to-right shunts in patients with a secundum atrial septal defect (ASD). Thirty-five consecutive patients with secundum ASDs underwent right heart catheterization and invasive oximetry. Phase-contrast magnetic resonance imaging (MRI) was performed for the main pulmonary artery and ascending aorta. All measurements were obtained during free breathing (FB) (quiet breathing; no breath-hold), expiratory breath-hold (EBH), and inspiratory breath-hold (IBH). Pulmonary circulation flow (Qp) and systemic circulation flow (Qs) were calculated by multiplying the heart rate by the stroke volume...

BACKGROUND: With the advent of bare metal stents and drug-eluting stents, percutaneous coronary intervention has emerged as an alternative to coronary artery bypass grafting surgery for unprotected left main disease. However, whether the evolution of stents technology has translated into better results after percutaneous coronary intervention remains unclear. We aimed to compare coronary artery bypass grafting with stents of different generations for left main disease by performing a Bayesian network meta-analysis of available randomized controlled trials...

Background Coronary artery perforation is a rare but serious complication of percutaneous coronary interventions. We aimed to evaluate the management of coronary artery perforation in Sulaimaniyah, Iraq. Methods A retrospective review of our medical records from 2009 to 2016 identified 24 patients (15 males, 9 females) with coronary artery perforation. Mean age was 60 ± 9.2 years (range 40-74 years). Standard diagnostic angiography or percutaneous interventions were performed. Coronary artery perforation was diagnosed by worsening of symptoms, hypotension, or angiographic evidence of type I (extraluminal crater), II (myocardial or pericardial blushing), or III (contrast streaming or cavity spilling) perforation...

We here present a comparative study of the Montmaurin-LN Middle Pleistocene mandible (Haute-Garonne, France). This mandible, of which its right and left molar series are preserved in situ, was found in La Niche cave (Montmaurin's karst system) in 1949, and was first attributed to the 'Mindel-Riss' interglacial (= MIS 9 to 11) based on its geological context. Later studies based on geological and faunal evidence have attributed the Montmaurin-LN mandible to MIS 7. Following a detailed morphological and metric comparative study of the mandible in the 1970s, it was interpreted in the light of a still limited fossil record and the prevailing paradigm back then...

A connectivity-based approach can highlight the network reorganization in the chronic phases after stroke and contributes to the development of therapeutic interventions. Using dynamic Bayesian inference, this study aimed to assess the effective connectivity(EC)in various frequency bands through the near-infrared spectroscopy(NIRS) method in subjects with cerebral infarction(CI). A phase-coupling model was established based on phase information extracted using the wavelet transform of NIRS signals. Coupling strength and the main coupling direction were estimated using dynamic Bayesian inference...

Though infrequent, left main stenosis has a major prognostic impact. The management of left main disease has evolved over the last few decades with the growing evidence of the efficacy and safety of percutaneous interventions, as attested by the most recent trials. However, mastery of the technical aspects of left main bifurcation stenting is essential in ensuring optimal results. This review focuses on recent data concerning left main angioplasty results as well as the current technical approaches.

Prevention of flares is a main goal in the long-term treatment of atopic dermatitis (AD). This study investigated the efficacy of a water-in-oil emollient, containing licochalcone A, omega-6-fatty acids, ceramide 3 and glycerol, for prevention of flares in adults with mild to moderately severe AD, who had been treated with topical steroids, which had led to clearing of the inflammatory lesions and had been discontinued prior to inclusion. The study was a 12-week, double-blind, randomized, vehicle-controlled, left-right comparison test with the number of relapses, defined as re-occurrence of erythema for at least 3 consecutive days, considered the primary outcome...

BACKGROUND: RNA folding is an ongoing compute-intensive task of bioinformatics. Parallelization and improving code locality for this kind of algorithms is one of the most relevant areas in computational biology. Fortunately, RNA secondary structure approaches, such as Nussinov's recurrence, involve mathematical operations over affine control loops whose iteration space can be represented by the polyhedral model. This allows us to apply powerful polyhedral compilation techniques based on the transitive closure of dependence graphs to generate parallel tiled code implementing Nussinov's RNA folding...

CONTEXT: A Kirschner wire (K-wire) is a stainless steel pin with at least one sharpened tip that is mainly used for the internal fixation of bone fractures. While some cases of K-wire dislocation and migration have been reported as complications after fracture surgery, the intraspinal migration of a K-wire is rare. Herein, we report a case in which a K-wire used for sternal fixation 7 years earlier migrated into the spinal canal. FINDINGS: A 68-year-old male suddenly sustained severe radiating pain and numbness in his left upper extremity, and walked to our hospital...

The uncinate fasciculus is the largest white matter association tract connecting the prefrontal cortex and the anteromedial temporal lobe. The traditional anatomical description outlines a temporal stem that hooks around the posterior insula, a subinsular body, and 2 prefrontal stems extending to the lateral orbital gyri and the frontopolar cortex. Recent imaging studies of the white matter tracts deep to the subgenual cingulate gyrus (Brodmann area 25: BA25) suggest the presence of white matter fibers extending from BA25 to the amygdala, via a route that would run in close proximity to the uncinate fasciculus, that are of functional importance in mood disorders...

OBJECTIVES: We sought to evaluate the independent predictive value of left main disease (LMD) and/or three-vessel disease (LMD/3VD) in acute myocardial infarction (AMI) patients. BACKGROUND: Patients with acute coronary syndrome resulting from LMD and/or three-vessel disease (LMD/3VD) are at the highest risk of adverse cardiovascular events. Neutrophil to lymphocyte ratio (NLR) has been proposed as a marker of cardiovascular risk, but the prognostic value of NLR in patients with LMD/3VD who underwent percutaneous coronary intervention (PCI) is not clearly defined...

This work is motivated by our goal of determining why individuals with stroke are impaired when locating their arms in space. We assessed the ability of individuals without neurological impairments to mirror their forearms during various motor tasks so that we could identify baseline performance in an unimpaired population. Nine right-hand dominant participants without neurological impairments mirrored forearm positions bi-directionally (i.e., right forearm mirrors left forearm, vice versa) for three motor tasks (i...
