BACKGROUND: Aging patients with cancer have a higher risk of mortality and treatment-associated morbidity than younger patients. Nutrition status may play an important role in cancer mortality. We aimed to evaluate the survival time of elderly patients with colorectal cancer and its association with body mass index (BMI), the patient-generated subjective global assessment (PG-SGA), and phase angle (PA). MATERIALS AND METHODS: BMI, PG-SGA, and PA were determined for all patients (n = 250) at first assessment...

A biofunctionalized reduced graphene oxide (rGO)-modified screen-printed carbon electrode (SPCE) was constructed as an immunosensor for C-reactive protein (CRP) detection, a biomarker released in early stage acute myocardial infarction. A different approach of single frequency analysis (SFA) study was utilized for the biomolecular sensing, by monitoring the response in phase angle changes obtained at an optimized frequency resulting from antigen-antibody interactions. A set of measurements were carried out to optimize a frequency where a maximum change in phase angle was observed, and in this case, we found it at around 10 Hz...

The aim of this study was to correlate patients with gastrointestinal cancer, classified according to different stages of cancer cachexia (SCC) as proposed by Fearon, with nutritional assessment tools such as PG-SGA, phase angle (PA), and handgrip strength. One hundred one patients with a mean age of 61.8 ± 12.8 yr, with 58.4% being men were included. 32.6% were malnourished according to the body mass index (BMI). A severe or moderate malnutrition had been diagnosed in 63.3% when assessed using the PG-SGA, 60...

Treatment of congestive heart failure (CHF) remains one of the challenging problems in cardiology. In recent years, the method of multifrequency bio-impendancemetry is used in patients with CHF for the assessment of water imbalance and determination of its severity. The aim of the study was to determine the diagnostic capabilities of bio-impendancemetry in evaluation of the early manifestations of CHF. The study included 92 healthy individuals, and 335 patients who were hospitalized in the cardiology department with NYHA I-II functional class (FC) of chronic CHF...

Optoelectronic plethysmography (OEP) is a noninvasive method for assessing lung volume variations and the contributions of different anatomical compartments of the chest wall (CW) through measurements of the motion of markers attached to the CW surface. The present study proposes a new method for analyzing the local CW kinematics from OEP measurements based on the kinematics of triangular Cosserat point elements (TCPEs). 52 reflective markers were placed on the anterior CW to create a mesh of 78 triangles according to an anatomical model...

OBJECTIVE: Respiratory muscle weakness frequently develops during mechanical ventilation, although in children there are limited data about its prevalence and whether it is associated with extubation outcomes. We sought to identify risk factors for pediatric extubation failure, with specific attention to respiratory muscle strength. DESIGN: Secondary analysis of prospectively collected data.

AC line-filtering on-chip micro-supercapacitors (MSCs) based on coordination polymer frameworks were fabricated by a facile layer-by-layer method. The reported on-chip MSCs showed a low impedance phase angle of -73° at 120 Hz and a high power density of up to 1323 W cm(-3) with a low relaxation time constant of 0.27 ms.

The purpose of the present study was to investigate the effect of two different resistance training (RT) prescription methods on phase angle (PA) in older women. Seventy-six older women (68.5 ± 5.7 years) were randomly assigned to one of three groups: two training groups that performed an eight-week RT programme either in a constant load (CT, n = 25) or an ascending pyramidal load (PR, n =  26) routine three times per week, or a control group (CG, n =  25) that performed no exercise. The CT programme consisted of three sets of 8-12 repetition maximum (RM) with a constant load for the three sets, whereas the PR training consisted of three sets of 12/10/8 RM with incremental loads for each set...

Accurate evaluation of fracture healing is important for clinical decisions on when to begin weight-bearing and when early intervention is necessary in cases of fracture nonunion. While the stages of healing involving hematoma, cartilage, trabecular bone, and cortical bone have been well characterized histologically, physicians typically track fracture healing by using subjective physical examinations and radiographic techniques that are only able to detect mineralized stages of bone healing. This exposes the need for a quantitative, reliable technique to monitor fracture healing, and particularly to track healing progression during the early stages of repair...

AIM: A tumor can induce abnormalities in vessel properties and the blood flow distribution. The aim of the present study was to determine if blood-pressure-waveform (BPW) harmonic indexes can be used to discriminate hemodynamic differences between healthy control subjects and patients with breast cancer. METHODS: Ten-minute bilateral radial BPW signals were obtained noninvasively in 23 breast-cancer patients and 23 healthy subjects. The amplitude proportion (Cn), phase angle (Pn), and harmonic variability (CVn) were calculated for harmonics 1 to 10 of the BPW...

PURPOSE: A high phase angle measured by the Nutriguard(®) bioelectrical impedance analysis device is associated with a reduced mortality risk in older people. This retrospective study aims to analyze whether this association persists with the other devices that have been used in our hospital. METHODS: This study encompasses all people 65 yrs and older who underwent a phase angle measurement between 1990 and 2011 at the Geneva University Hospitals, with the RJL-101(®) (RJL Systems), Xitron 4000B(®) (Xitron Technologies), Eugedia(®) (Eugédia-Spengler) and Bio-Z(®) (Spengler)...

INTRODUCTION: Running races on mountain trails at moderate-high altitude with large elevation changes throughout has become increasingly popular. During exercise at altitude, ventilatory demands increase due to the combined effects of exercise and hypoxia. AIM: To investigate the relationships between thoraco-abdominal coordination, ventilatory pattern, oxygen saturation (SpO2), and endurance performance in runners during high-intensity uphill exercise. METHODS: Fifteen participants (13 males, mean age 42±9 yrs) ran a "Vertical Kilometer," i...

Patients with advanced cancer often experience symptoms of disease and treatment that contribute to distress such as weight loss, which is present in up to 85% of cancer patients. Palliative care in these patients focuses on care aimed at improving quality of life. Phase angle (PA) is obtained by bioelectric impedance analysis (BIA) and is associated with cellular function. It is considered a reliable marker of malnutrition. A low PA may suggest deterioration of the cell membrane, which in palliative patients may result in a short-term survival...

OBJECTIVES: The purpose of this study is to use ECG-gated SPECT MPI to detect the latest contracting viable left ventricular (LV) segments to help guide the LV probe placement used in CRT therapy and to validate segment selection against the visual integration method by experts. METHODS: For each patient, the resting ECG-gated SPECT MPI short-axis images were sampled in 3D to generate a polar map of the perfusion distribution used to determine LV myocardial viability, and to measure LV synchronicity using our phase analysis tool...

The improper disposal of used frying oil (UFO) presents numerous ecological, environmental and municipal problems. Of great concern is the resultant blockage of municipal drainage systems and water treatment facilities, harm to wildlife when they become coated in it and detriment to aquatic life and ecosystems due to the depletion of the oxygen content in water bodies such as rivers and lakes that have become contaminated. Statistics show that in Trinidad and Tobago, in excess of one million liters of used cooking oil is collected annually from various restaurant chains...

AIM: To evaluate the prognostic value of the phase angle (PA) obtained from bioelectrical impedance analysis (BIA) for mortality prediction in patients with cirrhosis. METHODS: In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker (PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models...
