Abstract: This study investigated the effect of a visual memory training program on Chinese handwriting performance among primary school students with dyslexia in Hong Kong. Eight students of Grade 2 to 3 who were diagnosed with dyslexia were recruited. All participants received six sessions of training, which composed of 30-minute computerized game-based visual memory training and 30-minute Chinese character segmentation training. Visual perceptual skills and Chinese handwriting performance were assessed before and after the training, as well as three weeks after training using the Test of Visual Perceptual Skills (3rd edition) (TVPS-3) and the Chinese Handwriting Analysis System (CHAS). In comparing the pre- and post-training results, paired t-tests revealed significant improvements in visual memory skills, as well as handwriting speed, pause time and pen pressure after the training. There was no significant improvement in handwriting accuracy or legibility. The improved visual memory and handwriting performance did not show a significant drop at the follow-up assessments. This study showed promising results on a structured program to improve the Chinese handwriting performance, mainly in speed, of primary school children. The improvements appeared to be well-sustained after the training program. There is a need to further study the long-term effect of the program through a randomized controlled trial study.
Wavelet-Based Algorithm for Signal Analysis
Norman C. F. Tse,L. L. Lai
EURASIP Journal on Advances in Signal Processing , 2007, DOI: 10.1155/2007/38916
Abstract: This paper presents a computational algorithm for identifying power frequency variations and integer harmonics by using wavelet-based transform. The continuous wavelet transform (CWT) using the complex Morlet wavelet (CMW) is adopted to detect the harmonics presented in a power signal. A frequency detection algorithm is developed from the wavelet scalogram and ridges. A necessary condition is established to discriminate adjacent frequencies. The instantaneous frequency identification approach is applied to determine the frequencies components. An algorithm based on the discrete stationary wavelet transform (DSWT) is adopted to denoise the wavelet ridges. Experimental work has been used to demonstrate the superiority of this approach as compared to the more conventional one such as the fast Fourier transform.

Ensuring competency in end-of-life care: controlling symptoms
Frank D Ferris, Charles F von Gunten, Linda L Emanuel
BMC Palliative Care , 2002, DOI: 10.1186/1472-684x-1-5
Abstract: The EPEC Curriculum was developed to be a comprehensive syllabus including trainer notes, multiple approaches to teaching the material, slides, and videos of clinical encounters to trigger discussion are provided. The content was developed through a combination of expert opinion, participant feedback and selected literature review. Content development was guided by the goal of teaching core competencies not included in the training of generalist and non-palliative medicine specialist physicians.Whole patient assessment forms the basis for good symptom control. Approaches to the medical management of pain, depression, anxiety, breathlessness (dyspnea), nausea/vomiting, constipation, fatigue/weakness and the symptoms common during the last hours of life are described.While some physicians will have specialist palliative care services upon which to call, most in the world will need to provide the initial approaches to symptom control at the end-of-life.A wide range of symptoms produce considerable suffering in patients at the end of their lives. This monograph aims to summarize the core competencies in symptom control needed by any physician, no matter his or her specialty. Many of the approaches will apply much earlier in the course of the illness, not just at the end of life.The monograph does not purport to summarize specialist knowledge. While some practitioners will have specialist palliative care services upon which to call, most in the world will need to provide the initial approaches to symptom control at the end-of-life. This is not a fringe activity, but a core competency for physicians. After an overview of the approaches to whole patient assessment, we summarize the management of several of the more common symptoms that occur at the end-of-life.However, to focus on symptom control skills alone will miss the mark. To be effective in end-of-life care, physicians must also have a broad conceptualization of end-of-life care and the legal issues that support it
Feasibility of bioelectric impedance as a measure of muscle mass in mechanically ventilated ICU patients  [PDF]

Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.41008

Background: Critically ill patients receiving prolonged mechanical ventilatory support are at risk for loss of muscle mass and muscle strength from immobility. Feasible, non-invasive methods are needed to accurately obtain data on markers of muscle mass to design effective interventions and monitor patient progress during recovery from critical illness. Bioelectric impedance has been used in other settings to obtain data on body composition and muscle mass. Purpose: The aims of this study were to determine the feasibility of bioelectric impedance as a marker of muscle mass in a sample of mechanically ventilated patients and to assess data trends in these obtained values. Methods: A descriptive design was used to obtain standard bioelectric impedance parameters (total body resistance, legs resistance, and percent lean body mass) over 4 days from eligible patients already enrolled in a randomized clinical trial. Results: Bioimpedance parameters were readily obtained over 4 days in a sample of 43 patients (age 59 + 15.7 years, 56% male) receiving prolonged ventilatory support (mean 9.4 + 10.4 days) due to respiratory failure. Reasons for not obtaining impedance measures included skin impairment, monitoring devices, or presence of implantable cardiac defibrillator or pacemaker. Average total body impedance was 464.3 + 117.1 ohms, while average impedance of legs was 479.1 + 146.4 ohms. Lean body mass was 68.4% (+10.8). Conclusions/Implications for Practice: With carefully trained staff and a standardized measurement protocol, bioimpedance is a feasible method to obtain body composition data reflective of muscle mass in mechanically ventilated patients. Further research will determine the utility of bioimpedance to monitor recovery and effectiveness of interventions to restore function after prolonged periods of ventilatory support and immobility in mechanically ventilated patients.

Journal of Obesity , 2012, DOI: 10.1155/2012/934895
Abstract: The obesity epidemic requires the development of prevention policy targeting individuals most likely to benefit. We used self-reported prepregnancy body weight of all women giving birth in Nova Scotia between 1988 and 2006 to define obesity and evaluated socioeconomic, demographic, and temporal trends in obesity using linear regression. There were 172,373 deliveries in this cohort of 110,743 women. Maternal body weight increased significantly by 0.5 kg per year from 1988, and lower income and rural residence were both associated significantly with increasing obesity. We estimated an additional 82,000 overweight or obese women in Nova Scotia in 2010, compared to the number that would be expected from obesity rates of just two decades ago. The critical age for weight gain was identified as being between 20 and 24 years. This age group is an important transition age between adolescence and adulthood when individuals first begin to accept responsibility for food planning, purchasing, and preparation. Policy and public health interventions must target those most at risk, namely, younger women and the socially deprived, whilst tackling the marketing of low-cost energy-dense foods at the expense of healthier options.

Abstract: HealthCare Chaplaincy purchased the AHA survey database from the American Hospital Association. The Dartmouth Atlas of Health Care database was provided to HealthCare Chaplaincy by The Dartmouth Institute for Health Policy & Clinical Practice, with the permission of Dartmouth Atlas Co-Principal Investigator Elliot S. Fisher, M.D., M.P.H. The Dartmouth Atlas of Health Care is available interactively on-line at http://www.dartmouthatlas.org/ webcite. Patient data are aggregated at the hospital level in the Dartmouth Atlas of Health Care. IRB approval was not sought for the project because the data are available to the public through one means or another, and neither database contains data about individual patients, i.e. all the variables are measures of hospital characteristics. We combined and analyzed data from the American Hospital Association’s Annual Survey and outcome data from The Dartmouth Atlas of Health Care in a cross-sectional study of 3,585 hospitals. Two outcomes were examined: the percent of patients who (1) died in the hospital, and (2) were enrolled in hospice. Ordinary least squares regression was used to measure the association between the provision of chaplaincy services and each of the outcomes, controlling for six factors associated with hospital death rates.The analyses found significantly lower rates of hospital deaths (β?=?.04, p?<?.05) and higher rates of hospice enrollment (β?=?.06, p?<?.001) for patients cared for in hospitals that provided chaplaincy services compared to hospitals that did not.The findings suggest that chaplaincy services may play a role in increasing hospice enrollment. This may be attributable to chaplains’ assistance to patients and families in making decisions about care at the end-of-life, perhaps by aligning their values and wishes with actual treatment plans. Additional research is warranted.Most individuals in the United States (U.S.) who are seriously ill say they want to die at home [1]. Yet, research has consist
MTH1 and RGT1 demonstrate combined haploinsufficiency in regulation of the hexose transporter genes in Saccharomyces cerevisiae
Dietzel Kevin L,Ramakrishnan Vidhya,Murphy Erin E,Bisson Linda F
BMC Genetics , 2012, DOI: 10.1186/1471-2156-13-107
Abstract: Background The SNF3 gene in the yeast Saccharomyces cerevisiae encodes a low glucose sensor that regulates expression of an important subset of the hexose transporter (HXT) superfamily. Null mutations of snf3 result in a defect in growth on low glucose concentrations due to the inability to relieve repression of a subset of the HXT genes. The snf3 null mutation phenotype is suppressed by the loss of either one of the downstream co-repressor proteins Rgt1p or Mth1p. The relief of repression allows expression of HXT transporter proteins, the resumption of glucose uptake and therefore of growth in the absence of a functional Snf3 sensor. Results Strains heterozygous for both the RGT1 and MTH1 genes (RGT1/rgt1Δ MTH1/mth1Δ snf3Δ/snf3Δ) but homozygous for the snf3 were found to grow on low glucose. Since null alleles in the heterozygous state lead to suppression, MTH1 and RGT1 display the phenomenon of combined haploinsufficiency. This observed haploinsufficiency is consistent with the finding of repressor titration as a mechanism of suppression of snf3. Mutants of the STD1 homolog of MTH1 did not display haploinsufficiency singly or in combination with mutations in RGT1. HXT gene reporter fusion assays indicated that the presence of heterozygosity at the MTH1 and RGT1 alleles leads to increased expression of the HXT2 gene. Deletion of the HXT2 gene in a heterozygous diploid, RGT1/rgt1Δ MTH1/mth1Δ snf3Δ/snf3Δ hxt2Δ/hxt2Δ, prevented the suppression of snf3Δ. Conclusions These findings support the model of relief of repression as the mechanism of restoration of growth on low glucose concentrations in the absence of functional Snf3p. Further, the observation that HXT2 is the gene responsible for restoration of growth under these conditions suggests that the numbers of repressor binding domains found in the regulatory regions of members of the HXT family may have biological relevance and enable differential regulation.

Abstract: seventy-two crossbred pigs (landrace x large white) average initial body weight of 7.1kg and 20 crossbred pigs average initial body weight of 18.9kg were used in the performance and digestibility experiments to evaluate high-moisture corn silage with different particle sizes for piglets in nursery phase. a randomized block design was used. in both experiments the nutritional values of high-moisture corn silage with 979, 1168 and 2186μm geometric mean particle sizes (gm) and dry corn with 594μm gm were evaluated. from day 0 to 8, high-moisture corn silage provided daily feed intake (adfi) lower than dry corn. a linear increase was observed to this variable when increasing the particle size of the silage. the silage with intermediate and coarse particle sizes provided higher feed/weight gain than the dry corn, but no difference in average daily gain (adg) was observed. throughout the experimental period, there were no statistical differences in adfi and adg. therefore, the silage improved feed/weight gain in comparison to the dry corn. there was a linear increase of values of this variable as particle size of the silage increased. no effect of particle size of the silage on the apparent digestibility coefficients (adc) of dry matter and crude protein was observed. however, it provided higher phosphorus adc and values of digestible energy than the dry corn. calcium adc as well as values of metabolizable energy increased for silage with fine and intermediate particle sizes in comparison to the dry corn silage. calcium adc linearly decreased as the particle size of the silage increased.

Abstract: The purpose of the study was to examine the effects of two different training programs regarding reading skills in 14 reading disabled Swedish children in grade two. Method: The children’s results from two different decoding measures plus identification by teachers as having reading difficulties were used to select the participants. Seven of the children used Omega-IS, which entails computerized top-down, orthographic training and no additional homework, and seven children used non-computerized Reading Recovery inspired training with some components of phonological training included plus 20 homework occasions. For both programs the training sessions were conducted individually (one-to-one teaching) and lasted between 15 and 45 minutes. Results: Both groups improved significantly in all tests assessing word and non-word decoding as a result of the intervention. No significant differences were yielded between the intervention programs. Conclusion: The conclusion is that one-to-one teaching has a positive impact regardless whether a top-down or a reading instructional strategy with phonological components is implemented. Due to the result of the Omega-IS group it might also be possible to reduce homework for reading disabled children if reading is well tutored in school.
