Rehabilitation goals of people with spinal cord injuries can be classified against the International Classification of Functioning, Disability and Health Core Set for spinal cord injuries
Objectives:
To establish whether inter-professional rehabilitation goals from people with non-traumatic spinal cord injury (SCI) can be classified against the International Classification of Functioning, Disability and Health (ICF) SCI Comprehensive and Brief Core Sets early postacute situation.
Setting:
Neurological rehabilitation unit.
Methods:
Rehabilitation goals of 119 patients with mainly incomplete and non-traumatic SCIs were classified against the ICF SCI Core Sets following established linking rules.
Results:
A total of 119 patients generated 1509 goals with a mean (and s.d.) of 10.5 (9.1) goals per patient during the course of their inpatient rehabilitation stay. Classifying the 1509 rehabilitation goals against the Comprehensive ICF Core Set generated 2909 ICF codes. Only 69 goals (4.6%) were classified as ‘not definable (ND)’. Classifying the 1509 goals against the Brief ICF Core Set generated 2076 ICF codes. However, 751(49.8%) of these goals were classified as ‘ND’. In the majority of goals (95.7%), the ICF code description was not comprehensive enough to fully express the goals set in rehabilitation. In particular, the notion of quality of movement or specificity and measurability aspects of a goal (usually described with the criteria and acronyms SMART) could not be expressed through the ICF codes.
Conclusion:
Inter-professional rehabilitation goals can be broadly described by the ICF Comprehensive Core Set for SCI but not the Brief Core Set
Aspergillus species identification in the clinical setting
Multiple recent studies have demonstrated the limited utility of
morphological methods used singly for species identification of clinically
relevant aspergilli. It is being increasingly recognised that comparative
sequence based methods used in conjunction with traditional phenotype based
methods can offer better resolution of species within this genus. Recognising
the growing role of molecular methods in species recognition, the recently
convened international working group meeting entitled
“Aspergillus Systematics in the Genomic Era” has proposed
several recommendations that will be useful in such endeavors. Specific
recommendations of this working group include the use of the ITS regions for
inter section level identification and the β-tubulin locus for
identification of individual species within the various Aspergillus
sections
Impaired respiratory burst contributes to infections in PKCδ-deficient patients
Patients with autosomal recessive protein kinase C δ (PKCδ) deficiency suffer from childhood-onset autoimmunity, including systemic lupus erythematosus. They also suffer from recurrent infections that overlap with those seen in patients with chronic granulomatous disease (CGD), a disease caused by defects of the phagocyte NADPH oxidase and a lack of reactive oxygen species (ROS) production. We studied an international cohort of 17 PKCδ-deficient patients and found that their EBV-B cells and monocyte-derived phagocytes produced only small amounts of ROS and did not phosphorylate p40phox normally after PMA or opsonized Staphylococcus aureus stimulation. Moreover, the patients' circulating phagocytes displayed abnormally low levels of ROS production and markedly reduced neutrophil extracellular trap formation, altogether suggesting a role for PKCδ in activation of the NADPH oxidase complex. Our findings thus show that patients with PKCδ deficiency have impaired NADPH oxidase activity in various myeloid subsets, which may contribute to their CGD-like infectious phenotype
Controlo químico de infestantes
Uma planta é considerada infestante quando nasce espontaneamente num local e momento indesejados, podendo interferir negativamente com a cultura instalada.
As infestantes competem com as culturas para o espaço, a luz, água e nutrientes, podendo atrasar e prejudicar as operações de colheita, depreciar o produto final e assegurarem a reinfestação nas culturas seguintes.
Dado o modo de propagação diferenciado das diversas espécies de infestantes, com as anuais a propagarem-se por semente e as perenes ou vivazes a assegurarem a sua propagação através de órgãos vegetativos (rizomas, bolbos, tubérculos, etc.), assim, também o seu controlo quer químico, quer mecânico terá que ser diferenciado, ou seja, para controlar infestantes anuais será suficiente destruir a sua parte aérea, enquanto para controlar infestantes perenes teremos que destruir os seus órgãos reprodutivos.
O controlo de infestantes poderá ser químico, através da utilização de herbicidas, ou mecânico pela utilização de alfaias agrícolas, tais como a charrua de aivecas, a charrua de discos, a grade de discos, o escarificador e a fresa. Quando a técnica utilizada na instalação das culturas é a sementeira directa, o controlo das infestantes terá que ser obrigatoriamente químico, enquanto se o recurso à mobilização do solo for a técnica mais utilizada (sistema de mobilização tradicional ou sistema de mobilização reduzida), o controlo das infestantes tanto poderá ser químico como mecânico.
Neste trabalho iremos abordar apenas, o controlo químico de infestantes
Mechanical and Thermal Properties of Pumice Powder Filled PPS Composites
Recently, it is common application to use particle materials as fillers to improve engineering properties and lower the cost of finished product. Pumice powder is cheaper than most of traditional particle fillers, however use of pumice powders as a reinforcing material in composites has not been studied in literature. Hence, in this study we have investigated the mechanical and the thermal properties of pumice powder filled polyphenylenesulphide (PPS) composites. PPS composites were reinforced with pumice powder at different loading rates (0, 1, 3.5, and 10 wt%) and they were manufactured by twin screw extruder and injection molding machine. Thermal properties were investigated by thermogravimetric analysis and differential scanning calorimeter methods. Moreover, mechanical properties such as barcol hardness, tensile strength, and modulus of samples were investigated. Thermal properties of composite samples have varied significantly depending on the loading rate. Also mechanical properties of pumice powder filled PPS composites have showed better results than pure PPS. According to test results both of mechanical and thermal properties of composites have improved with pumice powder reinforcement and it is determined that pumice powders can be used instead of traditional particle fillers
Low pulse pressure as a predictor of death in patients with mild to advanced heart failure
PubMedID: 20548803The prognostic value of pulse pressure has been investigated in heart-failure patients. Low pulse pressure in advanced heart failure and high pulse pressure in mild heart failure have been separately linked to increased mortality rates. We prospectively investigated an association between pulse pressure and 2-year cardiovascular death in an entire heart-failure population. We prospectively enrolled 225 heart-failure patients (New York Heart Association [NYHA] functional class, I-IV; mean age, 56.5 ± 12.3 yr; 188 men). The patients' blood pressures were measured in accordance with recommended guidelines. Pulse pressures were calculated as the difference between systolic and diastolic blood pressure values. The patients were monitored for a mean period of 670 ± 42 days for the occurrence of cardiovascular death. All patients were divided into quartiles according to their pulse pressures (55 mmHg). Pulse pressure decreased as NYHA class worsened (P <0.001). Patients in the <35-mmHg quartile had the lowest plasma sodium concentrations, left ventricular ejection fractions, and systolic myocardial velocities upon echocardiography; and the highest left ventricular dimensions, early diastolic/late diastolic filling velocity ratios, and peak early/peak late diastolic myocardial velocity ratios. Pulse pressure independently predicted death in the patients with advanced heart failure and in the entire population. Upon receiver operating characteristic analysis, a 30-mmHg cutoff value for pulse pressure predicted death with 83.7% sensitivity and 79.7% specificity. Pulse pressure is easily calculated and enables the prediction of cardiovascular death in patients with mild to advanced heart failure. Pulse pressure can be used reliably as a prognostic marker in clinical practice. © 2010 by the Texas Heart® Institute, Houston
