The use of the concept of Bobath in improving patients of quantitative disorders of consciousness
Patients reduced states of consciousness, because of excessive duration and severity of illness require particular care effects in all aspects of medical applications. The process of medical rehabilitation in these cases comes up against difficulties related to the lack or limitation of the interaction between the therapist and the patient. For these reasons, always seek individual respiratory effects on the brain of the patient in order to most effectively induce Neuroplastic processes. It appears that the concept of Bobath may be a method of realization of the therapeutic agents in patients who are limited consciousness. It is understood that the method in accordance with the concept of physiotherapy Bobath comes down more to learn the patient feel performed passively or actively moving, not only to indicate to him how this movement should look like. Patients remaining in the states of limited consciousness are a unique group in which the interpretation of receipt by them of external stimuli is problematic and often impossible to determine. Regardless of whether the consciousness of the patient is under the control of, or is disabled, body position and movement patterns performed in the framework of rehabilitation allow to receive mechanical stimuli, thus contributing to the implementation of the appropriate movement patterns or even - to eliminate abnormal patterns. Possibly the quick implementation of rehabilitation Bobath method seems to be particularly important in patients who have suffered injuries of the central nervous system were in a coma or minimal consciousness
Disparities in Mortality Among Acute Myeloid Leukemia-Related Hospitalizations
Racial and socioeconomic disparities have become apparent in acute myeloid leukemia (AML) outcomes. We conducted a retrospective cohort study of hospitalizations for adults with a diagnosis of AML from 2009 to 2018 in the Nationwide Inpatient Sample (NIS). We categorized patients\u27 ages in groups of≥60 years and stratified them by reported race/ethnicity. Exposures of interest were patient sociodemographics, hospital characteristics, and Elixhauser-comorbidity Index. Outcome of interest was in-hospital death. Statistical analyses included survey logistic regression to generate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) to quantify the independent associations between patient characteristics and mortality. Of 622,417 AML-related hospitalizations, 57.6% were in patients ≥60 years. The overall rate of in-hospital death was 9.4%. Compared to patient
Some Findings Concerning Requirements in Agile Methodologies
gile methods have appeared as an attractive alternative to conventional methodologies. These methods try to reduce the time to market and, indirectly, the cost of the product through flexible development and deep customer involvement. The processes related to requirements have been extensively studied in literature, in most cases in the frame of conventional methods. However, conclusions of conventional methodologies could not be necessarily valid for Agile; in some issues, conventional and Agile processes are radically different. As recent surveys report, inadequate project requirements is one of the most conflictive issues in agile approaches and better understanding about this is needed. This paper describes some findings concerning requirements activities in a project developed under an agile methodology. The project intended to evolve an existing product and, therefore, some background information was available. The major difficulties encountered were related to non-functional needs and management of requirements dependencies
ALGORITHM FOR UPTAKE ASSESSMENT IN SMALL LESIONS BASED ON DYNAMIC SCINTIGRAPHY SCANS
The aim of our research was to develop an algorithm for estimation and visualisation of radiopharmaceutical uptake based on time-activity-curve (TAC) analysis in small regions of interest (ROI) in scintigraphic studies. The algorithm is implemented in Labview environment (National Instruments, Texas, Austin) and comprises the following steps: 1) delineation of grid of small ROIs over the examined tissue and corresponding TAC processing; 2) background vs tissue separation; 3) the extraction of all “suspected“ ROIs where TACs are not exponentially descendent; 4) correlation analysis between a TAC corresponding to the suspicious lesion ROI and TACs of neghboring ROIs; 5) the extraction of representative TAC for “suspected“ area by Principal Component Analysis technique; and 6) visual interpretation of radiopharmaceutical distribution in the “suspected“ area. The application of algorithm is presented in data recorded in case of histopathologically proven parathyroid tumors
Classical approach in duodenopancreatectomy - the key to success of a controversial intervention
Secția IV Chirurgie, Secția Radiologie, Secția Gastoenterologie, Spital ”Sf. Spiridon”, U.M.F. “Grigore T. Popa”, Iași, România, Al XIII-lea Congres al Asociației Chirurgilor „Nicolae Anestiadi” și
al III-lea Congres al Societății de Endoscopie, Chirurgie miniminvazivă și Ultrasonografie ”V.M.Guțu” din Republica MoldovaIntroducere: Duodenopancreatectomia cefalică (DPC) este considerată tratamentul standard pentru tumorile periampulare. În
pofida evoluției în chirurgia pancreatică, morbiditatea postoperatorie după DPC rămâne crescută. În timp ce rata mortalității asociate
intervenției chirurgicale a scăzut la mai puțin de 4%, morbiditatea postoperatorie se menține la mai mult de 50%, datorate în special
anastomozei pancreaticojejunale, principala vulnerabilitate a chirurgiei pancreatice.
Material și metode: Autorii prezintă un studiu pe 5 ani, între ianuarie 2014 și aprilie 2019, pe un lot de 17 pacienți la care s-a practicat
DPC cu reconstrucție clasică tip Whipple Child, cu 2 variante de anastomoză pancretico-jejunală. Media de vârstă a fost de 58,5.
Rezultate: Mortalitatea imediat postoperatorie în lotul studiat a fost de 0%, iar morbiditatea a fost reprezentată de 1 caz de fistulă
pancreatică și 2 cazuri de hemoragii postoperatorii. Supraviețuirea la 1 an a fost de 64,7%, 5 pacienți fiind pierduți din supraveghere
și 1 deces.
Concluzii: Fistula pancreatică, prin complicațiile cu pericol vital ca de exemplu hemoargia și peritonita, este principala cauză de
morbiditate și mortalitate după duodenopancreatectomie cefalică. Factorii care contribuie la această complicație sunt reprezentați de
textura moale a țesutului pancratic și de diametrul subțire al ductului pancreatic.Introduction: Pancreaticoduodenectomy (PD) is considered the standard treatment for periampullary tumors. Despite progresses
in pancreatic surgery, the postoperative morbidity after PD remains high. While the operation-associated mortality rate of pancreatic
surgery has decreased to less than 4%, the postoperative morbidity rate is reported to be as high as 50%, largely due to the
pancreaticojejunal anastomosis, the major vulnerability of pancreatic surgery.
Material and methods: The authors present a study between January 2014 and April 2019, on a series of 17 patients with PD with
classical reconstruction type Whipple Child, with 2 types of pancreaticojejunal anatomosis. The median age was 58,5.
Results: Postoperative mortality in the study was 0%, and morbidity was 1 case of pancreatic fistula and 2 postoperative bleeding.
The survival at 1 year was about 64,7%, 5 patients were lost under surveillance and one death.
Conclusions: Pancreatic fistula, with life-threatening complications, such as postoperative hemorrhage and peritonitis, is the most
important cause of morbidity and mortality in PD. Factors contributing to this complication are: soft pancreatic tissue texture and small
pancreatic duct diameter
Bond-disordered Anderson model on a two dimensional square lattice - chiral symmetry and restoration of one-parameter scaling
Bond-disordered Anderson model in two dimensions on a square lattice is
studied numerically near the band center by calculating density of states
(DoS), multifractal properties of eigenstates and the localization length. DoS
divergence at the band center is studied and compared with Gade's result [Nucl.
Phys. B 398, 499 (1993)] and the powerlaw. Although Gade's form describes
accurately DoS of finite size systems near the band-center, it fails to
describe the calculated part of DoS of the infinite system, and a new
expression is proposed. Study of the level spacing distributions reveals that
the state closest to the band center and the next one have different level
spacing distribution than the pairs of states away from the band center.
Multifractal properties of finite systems furthermore show that scaling of
eigenstates changes discontinuously near the band center. This unusual behavior
suggests the existence of a new divergent length scale, whose existence is
explained as the finite size manifestation of the band center critical point of
the infinite system, and the critical exponent of the correlation length is
calculated by a finite size scaling. Furthermore, study of scaling of Lyapunov
exponents of transfer matrices of long stripes indicates that for a long stripe
of any width there is an energy region around band center within which the
Lyapunov exponents cannot be described by one-parameter scaling. This region,
however, vanishes in the limit of the infinite square lattice when
one-parameter scaling is restored, and the scaling exponent calculated, in
agreement with the result of the finite size scaling analysis.Comment: 23 pages, 11 figures. RevTe
Evidence of acaricide resistance in different life stages of Amblyomma mixtum and Rhipicephalus microplus (Acari: Ixodidae) collected from the same farm in the state of Veracruz, Mexico.
The objectives of this study were to evaluate the resistance of Amblyomma mixtum and Rhipicephalus microplus ticks from co-infested bovines from the Veracruz region in Mexico to different acaricide families and to demonstrate the viability of the packet test on different A. mixtum instars. The following acaricide families were used: a combination (cypermethrin 15 g+chlorpyrifos 25 g+citronella 1 g+butoxide piperonyl 15 g), amidine (formamidine 12.5 g), pyrethroid (cypermethrin 15 g), and organophosphate (dichlorvos 60 g+chlorpyrifos 20 g). Regarding the packet test in both species, resistance was found for the pyrethroid and amidine families in A. mixtum and R. microplus, as efficacy did not surpass 40 %, including in immature instars; regarding the adult immersion test in R. microplus, the efficacy was 93.3 % for the amidine family and 26.2 % for the pyrethroid family. The proposed methodology is an alternative technique to optimize resistance detection in immature ticks with a heteroxenous life cycle
The level of air pollution in the impact zone of coal-fired power plant (Karaganda City) using the data of geochemical snow survey (Republic of Kazakhstan)
Coal-fired power plants emissions impact the air quality and human health. Of great significance is assessment of solid airborne particles emissions from those plants and distance of their transportation. The article presents the results of air pollution assessment in the zone of coal-fired power plant (Karaganda City) using snow survey. Based on the mass of solid airborne particles deposited in snow, time of their deposition on snow at the distance from 0.5 to 4.5 km a value of dust load has been determined. It is stated that very high level of pollution is observed at the distance from 0.5 to 1 km. there is a trend in decrease of dust burden value with the distance from the stacks of coal-fired power plant that may be conditioned by the particle size and washing out smaller ash particles by ice pellets forming at freezing water vapour in stacks of the coal-fired power plant. Study in composition of solid airborne particles deposited in snow has shown that they mainly contain particulates of underburnt coal, Al-Si- rich spheres, Fe-rich spheres, and coal dust. The content of the particles in samples decreases with the distance from the stacks of the coal-fired power plant
Water velocity limits the temporal extent of herbivore effects on aquatic plants in a lowland river
The role of herbivores in regulating aquatic plant dynamics has received growing recognition from researchers and managers. However, the evidence for herbivore impacts on aquatic plants is largely based on short-term exclosure studies conducted within a single plant growing season. Thus, it is unclear how long herbivore impacts on aquatic plant abundance can persist for. We addressed this knowledge gap by testing whether mute swan (Cygnus olor) grazing on lowland river macrophytes could be detected in the following growing season. Furthermore, we investigated the role of seasonal changes in water current speed in limiting the temporal extent of grazing. We found no relationship between swan biomass density in 1 year and aquatic plant cover or biomass in the following spring. No such carry-over effects were detected despite observing high swan biomass densities in the previous year from which we inferred grazing impacts on macrophytes. Seasonal increases in water velocity were associated with reduced grazing pressure as swans abandoned river habitat. Furthermore, our study highlights the role of seasonal changes in water velocity in determining the length of the mute swan grazing season in shallow lowland rivers and thus in limiting the temporal extent of herbivore impacts on aquatic plant abundance
