We included all consecutive nonagenarians presenting with STEMI admitted in 2 academic centers between 2007 and 2017. There were no exclusion criteria. We collected demographic, clinical, and procedural data. All-cause mortality was assessed in-hospital, at 6 months and at 1-year follow-up. |
A total of 140 patients (mean age 91.6 years [91.3–92]; 59% females) were included. The number of patients increased over the years (from 6.5 cases per year before 2012 to 14.4 cases per year after 2012). One out of 5 patients presented disability or dependence for activities of daily living (ADL). Emergent catheteriz... |
STEMI in nonagenarians is becoming more and more common. pPCI may be also the preferred strategy in this high-risk cohort. The hemodynamic compromise (Killip class III/IV), the presence of complications related to myocardial infarction and early revascularization may be related to prognosis of these patients. |
Chirp parameter estimation using rank reduction |
This paper considers the problem of estimating the bandwidth and the center frequency of a linear chirp signal from discrete-time noisy observations. The non-stationarity property of chirp signals implies that the signal has high rank and reduces the applicability of subspace based algorithms significantly. However, th... |
INTRODUCTION |
All people involved in transfusion therapy have professional, legal and ethical responsibility for their own actions. |
AIM |
The aims of the authors were to evaluate competencies, knowledge and practice of nurses about transfusion therapy. |
METHOD |
Descriptive statistical approach using observation, questionnaire survey and interview was applied. Reliability and validity of the self-made questionnaire were examined with statistical methods. Variance, standard deviation, Cronbach's alpha and Pearson correlations were calculated. |
RESULTS |
Transfusiology-related knowledge of nurses regarding current transfusion regulations was almost 90%, and 56.2% of nurses systematized the nursing functions correctly. Significant differences were found among different institutions in transfusion therapy, transfusion practice and the use of relevant documentation. 75-77... |
CONCLUSIONS |
The authors propose a better supervision by leaders in nursing aspects of transfusion therapy, and an increased professional responsibility.Exploring the Scalability Limits of Communication Networks at the Nanoscale |

In older adults, falls represent a very common and dangerous problem. Older adults lack the normal overlap or redundancy of cognitive, sensory, and musculoskeletal mechanisms that help younger people avoid falling while remaining active. Many of the risk factors for falls in older adults are modifiable and deserve aggr... |
BackgroundBrief episodes of ischemia induced by proximal coronary artery occlusion can precondition the myocardium. Whether other stressful stimuli have the potential to protect the myocardium from subsequent ischemia remains controversial.

Concerns about the depletion of fossil fuel reserves, the impact of anthropogenic CO2 emissions, and increasing energy demands have encouraged the exploration of new catalytic procedures for converting cellulosic biomass into valuable platform chemicals and renewable fuel components. The development of these sustainabl... |
The global growth in wind energy suggests that wind farms will increasingly be deployed in seismically active regions, with large arrays of similarly designed structures potentially at risk of simultaneous failure under a major earthquake. Wind turbine support towers are often constructed as thin‐walled metal shell str... |
A site-specific immunoconjugate was prepared between an F(ab')2-like fragment of the monoclonal anti-CEA murine IgG1 A5B7 and a mutant of the dimeric enzyme carboxypeptidase G2 possessing an N-terminal Thr in place of Ala. First an aldehyde was introduced at the N-terminus of the enzyme by mild periodate oxidation and ... |
An important issue of ant colony optimization (ACO) is how to keep the balance between the exploration in search space regions and the exploitation of the search experience gathered so far. By using a more exploitative pseudo-random-proportional selection rule, ant colony system (ACS) can obtain better results in exper... |
We quantified rotavirus A (RVA), Rotarix, and RotaTeq strains in oyster and sewage samples during two gastroenteritis seasons and revealed the exact contamination of wild-type RVA by subtracting the quantitative value of rotavirus vaccine strains from that of RVA. The concentration of wild-type RVA was significantly co... |
This paper studies the problem of discovering the most suitable resource for a specific request in a Grid system. A Grid can be seen as an environment comprised by routers and resources, where each router is in charge of its local resources. In our previous works we enhanced the routers of the system with matchmaking c... |
Uptake of arsenite by rat liver mitochondria is energy-dependent, as shown by comparing values without and with either uncoupling agent or respiratory inhibitor present. The uptake is inhibited by mersalyl and N-ethylmaleimide, which can be used as 'stopping' agents to obtain uptake kinetics. At 20 degrees C the proces... |
The phenomenon of differential charge distribution on sperm surface membrane has been utilised here in a low e.m.f. (electro motive force) capillary electrophoresis system to effect separation of sperm heads from disintegrated mixed spermatozoal subfractions. Washed caudal sperm of goat (Black Bengal variety) and ejacu... |
Nonprofit organizations are now involved in human service provision internationally. However, these organizations perform in variable ways that potentially undermine their public service function. Eldercare is a case in point. Drawing on various strands of organization theory and taking German care homes as an example,... |
Product benefits positioning theory has been well-known; it can create differences in product value. However, the product development to post-industrial society, not only the interests of the differences, but also produced a level of mutual (mutual benefit create relationship value).

Being confined within nanoscale space, substances may exhibit unique physicochemical properties. The effect of nanoconfinement on molecular interactions is of significance, but a sound understanding has not been established yet. Here we present a quantitative study on boronate affinity (covalent) and electrostatic (non... |
High concentrations of thyroid hormones can affect the metabolism of oxygen in aerobic conditions and stimulate free radicals generation in mitochondria. Reactive oxygen species are toxic to biomembranes and lead to peroxidation of lipids unless they are not removed by free radical scavengers. A few years ago melatonin... |
As cell and gene therapies (CGT) assume center stage in early‐phase clinical trials for several acute and chronic diseases, there is heightened interest in the standardization and automation of manufacturing processes in preparation for commercialization. Toward this goal, a hybrid and oftentimes geographically separat... |
Food. A provocative title in its simplicity, but by no means does Clapp provide a simple story of the forces that shape the world food economy and contribute to current food crises. Clapp establishes a framework of four basic forces that mediate the relationships between the usual story lines of supply and demand: the ... |
As educational institutions grow in size, network administrators for both K – 12 and higher education are finding their resources tapped for other purposes, and their staff sizes inadequate to meet the demands of evergrowing networks. The ODNM tool is presented which will allow system administrators to monitor wide are... |
OBJECTIVE |
To know the present situation about the follow-up of the patients with oral anticoagulant therapy (OAT) in primary care centers, the difficulties felt in its implantation and the professionals attitudes. |
DESIGN |
Cross-sectional descriptive study. |
SETTING |
All Spanish primary care centers. |
PARTICIPANTS |
The study subjects are the managers of all primary care centers. We selected a sample of 227 centers (the total number is 1854), for prevalence of 50%, confidence at 95%, precision 7% and 30% loss. The sample is stratified by regions. |
MEASUREMENTS AND MAIN RESULTS |
We sent a questionnaire by post to the managers of sample primary care centers. We sent a new mailing, after three months, to the "no answers". A rate of 72.7% answers were obtained. 23% of sample primary care centers do follow-up of OAT al less in a part of the patients. Reduced access to hospital is the only structur... |
CONCLUSIONS |
One every four Spanish primary care centers make the follow-up of OAT, higher when primary care centers are far away from hospital. So, accessibility is the factor with more influence in the decision of carry out OAT follow-up. Coordination with haematology services is the main problem to solve.Plesiomonas shigelloides... |

The order in which participants choose to recall words from a studied list of randomly selected words provides insights into how memories of the words are represented, organised, and retrieved. One pervasive finding is that when a pair of semantically related words (e.g., “cat” and “dog”) is embedded in the studied lis... |
Amidst the current cattle tuberculosis (TB) crisis, there is seemingly one pivotal misunderstanding that is responsible for prolonged chronic herd TB breakdowns, this is the inadequacy of current tests in use. In the current cattle TB crisis, attention has focused so much on badgers as the supposed main reservoir of TB... |
