Effect of Preoperative Home-Based Exercise Training on Quality of Life After Lung Cancer Surgery: A Multicenter Randomized Controlled Trial
Background. Preoperative exercise training is recommended for improvement of clinical outcomes after lung
cancer (LC) surgery. However, its efectiveness in preventing postoperative decline in quality of life (QoL) remains unknown. This study investigated the efect of preoperative home-based exercise training (PHET) on QoL after LC
surgery. Methods. Patients awaiting LC resection were randomized to PHET or a control group (CG). The PHET program combined aerobic and resistance exercise, with weekly telephone
supervision. Primary outcome was QoL-assessed with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQC30) at baseline, before surgery, and 1 month after surgery.
The secondary outcomes were hospital length of stay and physical performance. The main analysis included a factorial repeated-measures analysis of variance. Additionally, the proportion of patients experiencing clinical deterioration from baseline to post-surgery was assessed.
Results. The study included 41 patients (68.1±9.3 years; 68.3% male) in the intention-to-treat analysis (20 PHET patients, 21 CG patients). A signifcant group × time interaction was observed for global QoL (p =0.004). Betweengroup diferences in global QoL were statistically and clinically signifcant before surgery (mean diference [MD], 13.5 points; 95% confdence interval [CI], 2.4–24.6; p =0.019)
and after surgery (MD, 12.4 points; 95% CI, 1.3–23.4; p=0.029), favoring PHET. Clinical deterioration of global
QoL was reported by 71.4% of the CG patients compared with 30 % of the PHET patients (p =0.003). Between-group
diferences in favor of PHET were found in pain and appetite loss as well as in physical, emotional and role functions after surgery (p <0.05). Compared with CG, PHET was superior
in improving preoperative fve-times sit-to-stand and postoperative exercise capacity (p <0.05). No between-group diferences in other secondary outcomes were observed.
Conclusion. The study showed that PHET can efectively prevent the decline in QoL after LC surgery.info:eu-repo/semantics/publishedVersio
AVALIAÇÃO DE ADUBOS PROTEGIDOS NA PRODUTIVIDADE DO MILHO
Resumo – O objetivo do trabalho foi avaliar a influência da adubação protegida no plantio com NPK e em cobertura com a utilização de KCl e ureia, em diferentes dosagens. O experimento foi conduzido na Fazenda São José, situada no município de Paracatu, MG. O delineamento experimental foi de blocos ao acaso, sendo compostos por vinte tratamentos (doses de adubos na base e em cobertura) e cinco repetições. A utilização da adubação protegida na cultura do milho incrementou a produtividade milho, com as ressalvas de doses e formas do NPK, ureia e KCl. Palavras-chave: Doses. Polímero. Produtividade
Silício no crescimento e desenvolvimento de plantas de alface em cultivo fora do solo / Silence on growth and development of lettuce lettuce plants
O objetivo do trabalho foi avaliar os efeitos de concentrações de silício no crescimento e desenvolvimento de duas cultivares de alface em sistema de cultivo fora do solo. O experimento foi conduzido em casa de vegetação, no setor de Fitotecnia da UFSM. Os tratamentos foram compostos por cinco concentrações de silício na solução nutritiva: 0,0; 1,4; 2,8; 4,2 e 5,6 mmol L-1, duas cultivares (Stella e Veneranda) e pulverização foliar de silício aos sete dias antes da colheita. O delineamento experimental foi o inteiramente casualizado, com parcelas subdivididas, em esquema fatorial 5x2x2, com vinte e duas repetições. A maior massa fresca e seca da parte aérea foi observada para a cultivar Veneranda. O aumento da concentração de silício reduziu o crescimento e desenvolvimento das plantas de ambas as cultivares. Conclui-se que nas concentrações testadas não há efeito benéfico do silício na produção da alface em cultivo fora do solo

Phosphorus Is Associated with Coronary Artery Disease in Patients with Preserved Renal Function
High serum phosphorus levels have been associated with mortality and cardiovascular events in patients with chronic kidney disease and in the general population. In addition, high phosphorus levels have been shown to induce vascular calcification and endothelial dysfunction in vitro. The aim of this study was to evaluate the relation of phosphorus and coronary calcification and atherosclerosis in the setting of normal renal function. This was a cross-sectional study involving 290 patients with suspected coronary artery disease and undergoing elective coronary angiography, with a creatinine clearance >60 ml/min/1.73 m2. Coronary artery obstruction was assessed by the Friesinger score and coronary artery calcification by multislice computed tomography. Serum phosphorus was higher in patients with an Agatston score >10 than in those with an Agatston score ≤10 (3.63±0.55 versus 3.49±0.52 mg/dl; p = 0.02). In the patients with Friesinger scores >4, serum phosphorus was higher (3.6±0.5 versus 3.5±0.6 mg/dl, p = 0.04) and median intact fibroblast growth factor 23 was lower (40.3 pg/ml versus 45.7 pg/ml, p = 0.01). Each 0.1-mg/dl higher serum phosphate was associated with a 7.4% higher odds of having a Friesinger score >4 (p = 0.03) and a 6.1% greater risk of having an Agatston score >10 (p = 0.01). Fibroblast growth factor 23 was a negative predictor of Friesinger score (p = 0.002). In conclusion, phosphorus is positively associated with coronary artery calcification and obstruction in patients with suspected coronary artery disease and preserved renal function
Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory
The Auger Engineering Radio Array (AERA) is part of the Pierre Auger
Observatory and is used to detect the radio emission of cosmic-ray air showers.
These observations are compared to the data of the surface detector stations of
the Observatory, which provide well-calibrated information on the cosmic-ray
energies and arrival directions. The response of the radio stations in the 30
to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of
the incoming electric field. For the latter, the energy deposit per area is
determined from the radio pulses at each observer position and is interpolated
using a two-dimensional function that takes into account signal asymmetries due
to interference between the geomagnetic and charge-excess emission components.
The spatial integral over the signal distribution gives a direct measurement of
the energy transferred from the primary cosmic ray into radio emission in the
AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air
shower arriving perpendicularly to the geomagnetic field. This radiation energy
-- corrected for geometrical effects -- is used as a cosmic-ray energy
estimator. Performing an absolute energy calibration against the
surface-detector information, we observe that this radio-energy estimator
scales quadratically with the cosmic-ray energy as expected for coherent
emission. We find an energy resolution of the radio reconstruction of 22% for
the data set and 17% for a high-quality subset containing only events with at
least five radio stations with signal.Comment: Replaced with published version. Added journal reference and DO
Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy
We measure the energy emitted by extensive air showers in the form of radio
emission in the frequency range from 30 to 80 MHz. Exploiting the accurate
energy scale of the Pierre Auger Observatory, we obtain a radiation energy of
15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV
arriving perpendicularly to a geomagnetic field of 0.24 G, scaling
quadratically with the cosmic-ray energy. A comparison with predictions from
state-of-the-art first-principle calculations shows agreement with our
measurement. The radiation energy provides direct access to the calorimetric
energy in the electromagnetic cascade of extensive air showers. Comparison with
our result thus allows the direct calibration of any cosmic-ray radio detector
against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version. Added journal reference and DOI.
