Frailty is an increasingly common geriatric condition that results in an increased risk of adverse health outcomes such as falls. The most widely-used means of detecting frailty is the Fried phenotype, which includes several objective measures such as grip strength and gait velocity. One method of screening for falls is to measure balance, which can be done by a range of techniques including the assessment of the Centre of Pressure (CoP) during a balance assessment. The Balance Quality Tester (BQT) is a device based on a commercial bathroom scale that can evaluate balance quality...

Persons unable to exercise due to old age, immobility or medical condition may develop low bone density, decline in muscle contraction, blood pooling or clot. Due to musculoskeletal fragility caution is required in bone and muscle strengthening. Similarly, caution is required to use anticoagulant drug to prevent blood clot due to side effect, and compression devices are not as effective as drug. This paper presents a transcutaneous muscle fiber excitation system adaptable for use in seated, walking or lying position...

Predicting location of fracture in human bones has been a keen area of research for the past few decades. A variety of tests for hardness, deformation and strain field measurement have been conducted in the past; but considered insufficient due to various limitations. Researchers therefore have proposed further studies due to inaccuracies in measurement methods, testing machines and experimental errors. Advancement and availability of hardware, measuring instrumentation and testing machines can now provide remedies to these limitations...

Pneumonia is a disease which causes high mortality in children under five years old, particularly in developing countries. This paper proposes a novel application of ultrasound video analysis for the detection of pneumonia. This application is based on the processing of small video chunks, in which an image processing algorithm analyzes each frame to get some overall video statistics. Then, based on these quantities, the likeness of presence of pneumonia in the video is determined. The algorithm exploits different geometrical properties of typical anatomical and pathological features that commonly appear in lung sonography and which are already clinically typified in the literature...

A novel signal source estimation method using switching voltage divider technology was developed in our previous works. The aim of this method is to reduce the number of electrodes required for signal source estimation. Using this method, voltage and position information about the signal source inside the human body can be obtained simultaneously. The purpose of this paper is to estimate the changes in the signal source location according to ventricular activation. One healthy male (31 years old) participated in an ECG measurement experiment that utilized switching voltage divider technology...

The purpose of the present study was to test the efficacy of the empiric index SPIR (Second-phase Insulin Release) in the quantification of second-phase insulin secretion in the Zucker Fatty Rat. SPIR index is defined as the area under the curve of insulin between 8 and 90 min after an Intravenous Glucose Tolerance Test (IVGTT). The validation of such index was performed against the second-phase β-cell responsiveness index (Φ2) provided by C-peptide minimal model. To this aim, Φ2 and SPIR were simultaneously computed from IVGTT data, measured in six Zucker fatty rats (ZFR), 7-to-9week-old, and seven age-matched Zucker lean rats (ZLR)...

Investigating cognitive development of children poses interesting challenges pertaining to emergence of children's' ability to think and understand. Psychological tasks that involve conflict, like the Flanker task, are widely used to understand development of response conflict processes. In this study, EEG signals were used to examine the coherence and imaginary part of coherency within the delta, theta, alpha and beta bands across different conditions of the Flanker task. Longitudinal data were collected from a group of typically developing children at ages of seven and nine...

Recently we described an iterative skull conductivity and source location estimation (SCALE) algorithm for simultaneously estimating head tissue conductivities and brain source locations. SCALE uses a realistic FEM forward problem head model and scalp maps of 10 or more near-dipolar sources identified by independent component analysis (ICA) decomposition of sufficient high-density EEG data. In this study, we applied SCALE to 20 minutes of 64-channel EEG data and magnetic resonance (MR) head images from four twelve-months-of-age infants...

TNM staging is essential for clinical decision-making and prognostic prediction for patients with gastric cancer. The 7th TNM staging manual was formulated in 2009 and implemented in 2010. However, it was published that there were some deficiencies of the 7th edition of gastric cancer TNM staging system in clinical application process, and this old staging system could not meet the clinical needs. With the cooperation and promotion of the American Joint Committee on Cancer (AJCC), the International Union for Cancer Control (UICC) and the International Gastric Cancer Association (IGCA), and through the accumulation and analysis of gastric cancer big data, the 8th TNM staging system was published at the end of 2016...

Axenfeld-Rieger syndrome (ARS) is a clinically and genetically heterogeneous group of autosomal dominantly inherited malformations that predominantly affect the eye but are also associated with craniofacial dysmorphism and dental abnormalities. A broad spectrum of genetic alterations involving PITX2 and FOXC1 lead to ARS. We report on a 4-year-old girl with clinical features of ARS and developmental delay due to a de novo apparently balanced pericentric inversion in chromosome 4. This report emphasizes that complementary investigations are necessary to precisely characterize chromosomal rearrangements...

OBJECTIVE: We investigated cognitive reappraisal in children with ADHD by means of the late positive potential (LPP) and self-report ratings. We expected diminished LPP modulation following reappraisal and lower self-report scores in children with ADHD. METHODS: Eighteen children with ADHD and 24 typically developing (TD) children (8-12years) performed a cognitive reappraisal task, while EEG was recorded, and filled out a questionnaire on cognitive reappraisal. RESULTS: Despite the lack of main reappraisal effects on LPP, the LPP was less positively modulated during reappraisal in ADHD compared to TD children...

We milled granular activated carbons (GACs) that had been used for 0-9 years in water treatment plants and produced carbon particles with different sizes and ages: powdered activated carbons (PAC, median diameter 12-42 μm), superfine PAC (SPAC, 0.9-3.5 μm), and submicron-sized SPAC (SSPAC, 220-290 nm). The fact that SPAC produced from 1-year-old GAC and SSPAC from 2-year-old GAC removed 2-methylisoborneol (MIB) from water with an efficiency similar to that of virgin PAC after a carbon contact time of 30 min suggests that spent GAC could be reused for water treatment after being milled...

The article discusses drug abuse and eating disorders from the critical gender and healthcare perspectives, postulating that subjective suffering can be expressed in the body through psychosomatic illnesses. From this perspective, craving for drugs or superfluous consumer goods, just as illness from self-imposed hunger in pursuit of an ideal of slimness, as in anorexia and bulimia, can be symptoms that expose the woman's suffering. A review in the fields of public health and feminist theories highlights the magnitude of the phenomena of medicalization and commodification of health in the psychiatrization of female discomfort...
