Use and Effects of Health Information Technologies in Surgical Practice
No full textIncreasing health information technology (HIT) adoption has led to growth in research on its implementation and use, the majority of which has been conducted in primary care and medical specialty settings. This thesis comprises three research projects that expand the knowledge base about HIT in surgery. A systematic review summarized the evidence about the effects of major categories of HIT (e.g., electronic health records, computerized order entry) on surgical outcomes and demonstrated improvement in the quality of surgical documentation, increased adherence to guidelines for perioperative prophylactic medication administration, and improvements in patient care with provider alerts. The review identified gaps in the literature about consumer HIT use by surgical patients and providers. A second study demonstrated modest use of a patient portal by surgical patients during hospitalizations and found increased inpatient use for patients who were white, male, and had longer lengths of stay. This study showed that a patient portal designed for the outpatient setting could be employed by surgical patients during hospitalizations. A third study analyzed the nature of the communications in patient portal messages threads between surgeons and their patients. Two-thirds of message threads involved medical care with predominantly straightforward and low complexity decision-making. This study highlighted the need for expanded models for compensation of online care. This thesis provides insights into the use and effects of HIT in surgical practice. As HIT continues to evolve, the unique perspectives of surgical providers and patients should be represented in the design, implementation, evaluation, and regulation of its use
Liquid helium flows around an oscillating cylinder
No full textThe complementary flows of normal viscous liquid helium (He I) and of superfluid helium (He II) around an oscillating obstacle, of rectangular cross-section, have been studied experimentally by using the particle tracking velocimetry technique, with solid deuterium particles. The observed particle behaviour in He II is very similar to that seen in He I. It seems therefore that, without some kind of special forcing acting differently on each superfluid helium component, on length scales which the experiment can access, the oscillating quantum flow mimics the classical one
Factores de riesgo para transformación hemorrágica post tratamiento trombolítico endovenosos en accidente cerebrovascular agudo en el servicio de emergencia del Hospital Nacional Edgardo Rebagliati Martins en el periodo julio 2019 – junio 2022
No full textEl accidente cerebrovascular es la segunda causa de muerte más frecuente en el mundo y la principal causa de discapacidad en adultos. A medida que aumenta la esperanza de vida, la carga de accidentes cerebrovasculares aumenta en todo el mundo, especialmente en países de ingresos medios y bajos(1). En el Perú, se ha reportado que el 15% de todas las muertes prematuras son causadas por el ACV. Su prevalencia es de 6,8% en zonas urbanas y 2,7% en zonas rurales. Presenta una mayor incidencia en personas mayores de 65 años y una tendencia creciente tanto en incidencia como en mortalidad en los últimos años (2).
La trombólisis intravenosa (IVT) sigue siendo el tratamiento estándar para pacientes con accidente cerebrovascular isquémico agudo (AIS) dentro de las 4,5 horas posteriores al inicio y puede mejorar el pronóstico clínico y reducir la mortalidad. Sin embargo, puede causar complicaciones graves, especialmente la transformación de la hemorragia intracerebral (HT), lo que conduce a un deterioro de la función neurológica clínica y un mal pronóstico, lo que limita el uso más generalizado de la IVT (3).
Existe una fuerte evidencia sobre las variables que implican mayor riesgo de transformación hemorrágica tras IVT (mayor edad, valores altos en la escala NIHSS, cifras de presión arterial sistólica elevada, niveles elevados de glucosa, género masculino, largo período transcurrido entre el comienzo de los síntomas y la implementación del tratamiento, consumo previo de antiagregantes plaquetarios y/o anticoagulantes) (4).
Identificar pacientes con alto riesgo de transformación hemorrágica post trombólisis endovenosa podría permitir adoptar medidas precoces para prevenirla. Lo cual es importante ya que la transformación hemorrágica se ha asociado previamente a un mayor riesgo de deterioro y mortalidad a los 3 meses y puede ser una causa de preocupación ante la duda de iniciar IVT o no (2)Submitted by Veronica RubinDeCelis ([email protected]) on 2023-04-12T21:54:14Z

Más allá de la "duda" de Hamlet
No full textThe author presents the connection between Hamlet's doubt and the relationship
between presence and abscence in M. F. Sciacca's phylosophy. She studies the
philosophic aspects of doubt and dilemma, of alternative, and of the need to
choose between two opposing solutions. The paper presents the laceration of a
human being living his self as an irreconcilable tragedy. The author also analyses
the idea of human freedom and human finitude that Sciacca understands exist in
this world, yet, this finitude bears the presence of the infinite within itself.La autora pone de manifiesto la relación entre la duda de Hamlet y
la relación de la presencia y de la ausencia en la filosofía de M. F. Sciacca.
Analiza los aspectos filosóficos de la duda y del dilema, la alternativa, la necesidad
de elegir entre dos contrastantes soluciones. Se presenta la laceración de un
hombre que vive su ser como drama inconciliable. Se analiza luego la idea de
libertad en ser humano y en su finitud, que Sciacca concibe como existente en el
mundo, mas con una finitud que tiene dentro la presencia de lo infinito
Aptilotella borgmeieri Duda
No full textAptilotella borgmeieri Duda Aptilotella borgmeieri Duda, 1924: 74. The second author was unable to locate the type series of Aptilotella borgmeieri at MZSP. Since these specimens have apparently been lost, the following redescription of the male is adapted from Duda’s original German description in 1924. Gapasin (1972) and Smith (1994) both redescribed A. borgmeieri based on Duda (1924) and specimens that originated from “a long series in São Paulo [MZSP]” collected by F. Plaumann on an unknown date at 300–600 m in Nova Teutonia (abbreviated NT), Brazil. The structural characters recorded from this specimen by Smith (1994) are inconsistent with Duda’s description, including a reduced orbital bristle and double rows of interfrontal setae. Gapasin (1972) examined a single female from the NT series and illustrates a pair of bean-shaped spermathecae. No such spermathecal morphology is known in other Aptilotella. It is possible that Gapasin (1972) illustrated the deflated paired spermathecae, while the third spermatheca was either lost or overlooked. The NT series originated from Serra Geral, a mountain range separate from the Serra Da Mantiqueira Mountains in which the type locality of A. borgmeieri is situated. Because of uncertainty about the identity of the species described by Gapasin (1972) and Smith (1994), their notes are not reflected in the redescription below. Description. Body length 0.9 mm. Head ground color dark brown. Frons black, shining; with a pair of narrow, parallel grey stripes. Ocelli absent; ocellar bristle three quarters the length of frons. Interfrontal setae minute, in two or three pairs. Several pairs of orbital setulae present. Orbital and vertical bristles absent. Face and gena shining; lunule, clypeus, and gena black. Body black, shining. Scutum twice wider than long; sparsely microtrichose. Scutellum approximately twice wider than long. Pleuron black. Legs brown; tarsi light brown; mid tibia with two anterodorsal bristles. Wings absent. Abdomen with large syntergite approximately the length of the other tergites combined. Terminalia. Duda (1924) vaguely noted synsternite 6+7 and the epandrium, but did not describe any genitalic characters or dissect any specimens. Type material. Holotype ♂ (MZSP, not examined and probably lost). BRAZIL: Petrópolis, T. Borgmeier. Comments. Duda’s original description is nebulous, but seems to be consistent with Clade 2. Aptilotella borgmeieri most closely resembles A. viva, from which it differs by the shining black body, dark colouration of the frons and gena, long ocellar bristle, and a few pairs of interfrontal setae and orbital setulae. In A. borgmeieri, the enlargement of the syntergite is far more pronounced than in other Aptilotella species. This is somewhat also noticeable in A. viva. An equivalent enlarged syntergite occurs in a remarkably similar undescribed Howickia species in New Zealand. This similarity is clearly due to convergence, and is not reflected in genitalic characters. Aptilotella borgmeieri is the presently the only described species of Aptilotella from eastern South America.Published as part of Luk, Stephen P.

Na omówiony syndrom wenecki składają się cechy, prawidłowości i właściwości związane z funkcjonowaniem miasta historycznego na różnych płaszczyznach: społecznej, ekonomicznej (gospodarka i zarządzanie miastem), przestrzennej.The article presents an interpretative scheme that identifies and allows to understand the negative effects of tourism development in the historic cities. Their choice is based mainly on the example of Venice, but also other European cities – including (among other) Kraków using available publications and research results. The dysfunctions of the tourism development in a heritage city conventionally named by the author “Venice syndrome” consist of features, regularities and characteristics visible in the various levels of functioning of a historic city: social (residents, tourists), economic (economy and city management), spatial and others (e.g. ecological)

Visualization of selected flows of superfluid helium using solid hydrogen tracer particles
No full textDaniel Duda Visualization of selected flows of superfluid helium using solid hydrogen tracer particles 5 Thesis title: Visualization of selected flows of superfluid helium using solid hydrogen tracer particles Author: Bc. Daniel Duda Department: Department of Low Temperature Physics, Supervisor: prof. RNDr. Ladislav Skrbek, DrSc, Department of Low Temperature Physics, Faculty of Mathematics and Physics, Charles University in Prague. Consultant: Dr. Marco La Mantia, PhD. Abstract: Quantum turbulence generated in thermal counterflow of He II is studied experimentally by visualization. The statistical properties of the motion of micron size solid deuterium particles are studied by using the particle tracking velocimetry technique at length scales comparable to the mean distance between quantized vorti- ces. The probability density function (PDF) of the longitudinal velocity displays two peaks that correspond to two velocity fields of the two-fluid description of He II. The PDF of the transversal velocity displays a classical-like Gaussian core with non- classical power-law tails, confirming the quantum nature of turbulence in counter- flowing He II. The distribution of the particle acceleration is found to be similar in shape to the classical one, in the range of investigated parameters. The observed de-..
