Comparison of hospital-based versus home-based exercise training in patients with heart failure: effects on functional capacity, quality of life, psychological symptoms, and hemodynamic parameters

Abstract: To compare the effects of home-based and hospital-based exercise programs on exercise capacity, quality of life, psychological symptoms, and hemodynamic parameters in heart failure (HF) patients. Seventy-four patients were randomized into either a hospital-based exercise (Group 1) or a home-based exercise (Group 2) group. Prior to and after the 8-week rehabilitation program, the two groups were compared with respect to their functional capacity [maximal oxygen uptake (pVO2) and 6-min walk test (6MWT)], quality of life (Medical Outcomes Study and the 36-item Short Form Survey, SF-36), psychological symptoms [Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory], and hemodynamic parameters [(left ventricular diastolic diameter in diastole, left ventricular diameter in systole, Mitral Early diastolic peak flow velocity (E)/late diastolic peak flow velocity (A), Mitral E/Mitral early peak velocity (E m), Tei index, right ventricular systolic peak velocity (S m), tricuspid annular plane systolic excursion, systolic pulmonary arterial pressure (SPAP), and left and right ventricular ejection fraction (LVEF and RVEF)]. After the exercise programs, significant improvement was observed in pVO2, 6MWT and subscales of physical function, general health, and vitality of SF 36, as well as BDI and LVEF in both groups (P 0.05). Both the hospital-based and home-based exercise groups improved significantly in functional capacity, quality of life, depression symptoms, and LVEF. Based on these results, we believe that physicians can recommend home-based exercise under strict supervision for stable HF patients. However, additional research should be conducted in this area.

Analytical solutions to the pulsed Klein-Gordon equation using Modified Variational Iteration Method (MVIM) and Boubaker Polynomials Expansion Scheme (BPES)

Abstract: In this study, we propose an analytical solution to the Klein-Gordon equation in a pulsed stationary regime. The performed protocols are based on the modified variational iteration method MVIM and Boubaker polynomials expansion scheme BPES. The results are presented, and compared with some solutions proposed later in order to confirm the good accuracy of the protocols used.

ROS and RNS: Key signalling molecules in plants

Abstract: Both reactive oxygen species (ROS) and reactive nitrogen species (RNS) are important signals in plants and key regulators of a variety of processes including metabolism, growth and development, response to abiotic and biotic stresses, solute transport, autophagy and programmed cell death (PCD). The reviews and original research in this special issue reflect a burgeoning area of investigation, and highlight the latest thinking on new roles and interactions of ROS and RNS, the basis of their specificity and flexibility, and emergent fields.

Biofilm formation in an ice cream plant.

Abstract: The sites of biofilm formation in an ice cream plant were investigated by sampling both the production line and the environment. Experiments were carried out twice within a 20-day period. First, stainless steel coupons were fixed to surfaces adjacent to food contact surfaces, the floor drains and the doormat. They were taken for the analysis of biofilm at three different production stages. Then, biofilm forming bacteria were enumerated and also presence of Listeria monocytogenes was monitored. Biofilm forming isolates were selected on the basis of colony morphology and Gram's reaction; Gram negative cocci and rod, Gram positive cocci and spore forming isolates were identified. Most of the biofilm formations were seen on the conveyor belt of a packaging machine 8 h after the beginning of the production, 6.5 x 10(3) cfu cm(-2). Most of the Gram negative bacteria identified belong to Enterobacteriaceae family such as Proteus, Enterobacter, Citrobacter, Shigella, Escherichia, Edwardsiella. The other Gram negative microflora included Aeromonas, Plesiomonas, Moraxella, Pseudomonas or Alcaligenes spp. were also isolated. Gram positive microflora of the ice cream plant included Staphyloccus, Bacillus, Listeria and lactic acid bacteria such as Streptococcus, Leuconostoc or Pediococcus spp. The results from this study highlighted the problems of spread of pathogens like Listeria and Shigella and spoilage bacteria. In the development of cleaning and disinfection procedures in ice cream plants, an awareness of these biofilm-forming bacteria is essential for the ice cream plants.
