An Indoor Visible Light Communication Positioning System Using a RF Carrier Allocation Technique

We propose a new indoor positioning system utilizing visible light communication. Intensity modulation/direct detection and carrier allocation methods are utilized in the proposed system. Simultaneous three channel transmissions were applied to calculate the receiver's position. The characteristics of the proposed positioning system were investigated through simulation based on the experimental results, and the feasibility of the proposed system was verified by experimentation. The experimental result shows that the average error of estimated positions is reduced to 2.4 cm using adjustment process by normalizing method, which is compared with 141.1 cm without adjustment process.
High Tibial Osteotomy Using a Dynamic Axial External Fixator

High tibial osteotomy is an accepted treatment for unicompartmental osteoarthritis of the knee. Conventional osteotomy can be a demanding procedure with potential for complications. Opening wedge high tibial osteotomy using an external fixator is an alternative that may have advantages in comparison with classic methods. The aims of the current study were to determine if opening wedge osteotomy using hemicallotasis techniques is safer than, and the outcome comparable with that of, conventional techniques. Seventy-six high tibial osteotomies were performed in 65 patients for primary osteoarthritis. The mean age of the patients was 54.8 years (range, 36–70 years). The mean followup was 6 years. The only serious complication occurred in one patient, who had chronic osteomyelitis develop 2 years after surgery. There were no neurologic or vascular complications. The authors think this technique is safer than conventional techniques. Survivorship at 5 and 10 years was 89% and 63%, respectively. The mean knee score in osteotomies was 26.6 (maximum possible score, 48). The outcome is comparable with, or better than, that of other techniques for osteotomy. Subsequent knee replacement, in cases requiring conversion, was straightforward. The mean score in knees that had osteotomies that were converted to total knee replacements was 33.7.
Self-reported measurement of heart rate and blood pressure in patients by physical therapy clinical instructors.

BACKGROUND AND PURPOSE The Guide to Physical Therapist Practice (Guide) recommends that heart rate (HR) and blood pressure (BP) measurement be included in the examination of new patients. The purpose of this study was to survey physical therapy clinical instructors to determine the frequency of HR and BP measurement in new patients and in patients already on the physical therapists' caseload. The use of information obtained from HR and BP measures in decision making for patient care and the effects of practice setting and academic preparation on the measurement and use of HR and BP also were examined. SUBJECTS AND METHODS A sample of 597 subjects was selected from a list of 2,663 clinical instructors at the clinical education sites of the 2 participating universities. Clinical instructors from a variety of practice settings were surveyed. A 26-item survey questionnaire was mailed to the clinical instructors. RESULTS Usable survey questionnaires were received from 387 respondents (64.8%); 43.4% reported working in an outpatient facility. The majority of the respondents strongly agreed or agreed (59.5%) that measurement of HR and BP should be included in physical therapy screening. When asked if routinely measuring HR and BP during clinical practice is essential, opinions were nearly split (strongly agree or agree=45.0%, strongly disagree or disagree=43.7%, no opinion=11.3%). More than one third (38.0%) of the respondents reported never measuring HR in the week before the survey as part of their examination of new patients. A slightly larger percentage (43.0%) reported never measuring BP of new patients in the week before the survey. Conversely, 6.0% and 4.4% of the respondents reported always measuring HR and BP, respectively, of new patients in the week before the survey. When given a list of reasons why HR and BP were not routinely measured in their clinical practice, respondents most frequently chose "not important for my patient population" (52.3%). Relationships were found between practice setting and frequency of HR and BP measurement in new patients. DISCUSSION AND CONCLUSION Practices related to HR and BP measurement reported by this sample of clinical instructors do not meet the recommendations for physical therapy care described in the Guide.
Prognostic significance of the EGFR pathway in nasopharyngeal carcinoma: a systematic review and meta-analysis.

OBJECTIVE To evaluate the prognostic impact of the EGF receptor (EGFR) pathway molecules and assess their clinical usefulness. METHODS We conducted a systematic review. Pubmed and EMBASE were searched January 2014. The prognostic relevance of EGFR, JAK, PI3K, PIK3CA, STAT3, STAT5, PTEN, AKT, mTOR, GRB2, SOS, RAF, RAS, MAPK, ERK, MEK and CCND1 in nasopharyngeal carcinoma was assessed. The outcomes considered were overall survival, disease-free survival and tumor-node-metastasis stage. Twenty-two studies were included. Risk of bias was evaluated. Meta-analysis for which pooled hazard ratios and 95% CIs were calculated. CONCLUSION EGFR overexpression predicts a worse overall survival and disease-free survival in nasopharyngeal carcinoma, but no specific causal pathway molecule could be identified.

Anxiety and Quality of Life of Parents with Children Diagnosed with an Anorectal Malformation or Hirschsprung Disease

Abstract Aim The aim of this study was to investigate the difference in anxiety and quality of life (QOL) between mothers and fathers of children with anorectal malformations (ARM) or Hirschsprung disease (HD). In addition, anxiety of parents of newborns was compared with parents of children in the age-group of 10 to 13 years. Methods Parents of 44 patients with ARM or HD completed the World Health Organization Quality of Life (WHOQOL)-BREF (26 items) and the Spielberger State-Trait Anxiety Inventory (STAI-trait 10 items, STAI-state 6 items). They were divided into two groups according to their children's age (0–4 years and 10–13 years). Results Overall mothers scored significantly worse than fathers on state anxiety (p = 0.005). Trait anxiety was not significantly different between mothers and fathers. The psychological domain of the WHOQOL-BREF was significantly different between parents (p = 0.016), with mothers scoring worse. Dividing the group in newborns and school going children mothers of newborns showed significantly more state anxiety compared with fathers of newborns (p = 0.016). In the group of older children, both anxiety and QOL were not significantly different between fathers and mothers. Comparing mothers of newborns with mothers of older children, the first group scored higher on state anxiety, but this difference was not significant (p = 0.138; 95% confidence interval, 0.535–3.717). Conclusions Mothers of newborns have a higher level of anxiety than fathers of newborns with ARM or HD. When children with ARM or HD become older, this difference in anxiety between parents is not significant anymore. This may be explained by coping strategies.
Modelling sediment pick-up and deposition in a dune model

Often river bed form modelling is done with an equi librium bed load transport formula like that of Mey er-Peter & Müller (1948). However, a physically more correct w ay would be to model it with separate models for th e sediment pick-up and deposition processes as descri b d by Nakagawa & Tsujimoto (1980). Besides the phy sics of the sediment transport itself, using such a method allows for the modelling of higher-order processes as well like spatial lag in bed load transport. As shown by Shimizu et al. (2009) applying the afor ementioned pick-up and deposition model in a dune e volution model, makes is possible to model dunes well. Speci fically it made it possible to determine a transiti on to upper stage plane beds, as well as capturing hysteresis w ell. In this paper we will explore the effect of using d ifferent kinds of bed load models in a relatively s imple dune evolution model. The Nakagawa & Tsujimoto (1980) be d load model, will be implemented in the dune evolu ti n model of Paarlberg et al. (2009). Results of this m odel version will be compared with the original ver sion (using the Meyer-Peter & Müller formula) and a later versi on that directly models spatial lag with a relaxati on equation.
Incremental health care costs for chronic pain in Ontario, Canada: a population-based matched cohort study of adolescents and adults using administrative data

Abstract Little is known about the economic burden of chronic pain and how chronic pain affects health care utilization. We aimed to estimate the annual per-person incremental medical cost and health care utilization for chronic pain in the Ontario population from the perspective of the public payer. We performed a retrospective cohort study using Ontario health care databases and the electronically linked Canadian Community Health Survey (CCHS) from 2000 to 2011. We identified subjects aged ≥12 years from the CCHS with chronic pain and closely matched them to individuals without pain using propensity score matching methods. We used linked data to determine mean 1-year per-person health care costs and utilization for each group and mean incremental cost for chronic pain. All costs are reported in 2014 Canadian dollars. After matching, we had 19,138 pairs of CCHS respondents with and without chronic pain. The average age was 55 years (SD = 18) and 61% were female. The incremental cost to manage chronic pain was $1742 per person (95% confidence interval [CI], $1488-$2020), 51% more than the control group. The largest contributor to the incremental cost was hospitalization ($514; 95% CI, $364-$683). Incremental costs were the highest in those with severe pain ($3960; 95% CI, $3186-$4680) and in those with most activity limitation ($4365; 95% CI, $3631-$5147). The per-person cost to manage chronic pain is substantial and more than 50% higher than a comparable patient without chronic pain. Costs are higher in people with more severe pain and activity limitations.

Long-Term Shifts in Patterns of Antibiotic Resistance in Enteric Bacteria

ABSTRACT Several mechanisms are responsible for the ability of microorganisms to tolerate antibiotics, and the incidence of resistance to these compounds within bacterial species has increased since the commercial use of antibiotics became widespread. To establish the extent of and changes in the diversity of antibiotic resistance patterns in natural populations, we determined the MICs of five antibiotics for collections of enteric bacteria isolated from diverse hosts and geographic locations and during periods before and after commercial application of antibiotics began. All of the pre-antibiotic era strains were susceptible to high levels of these antibiotics, whereas 20% of strains from contemporary populations ofEscherichia coli and Salmonella entericadisplayed high-level resistance to at least one of the antibiotics. In addition to the increase in the frequency of high-level resistance, background levels, conferred by genes providing nonspecific low-level resistance to multiple antibiotics, were significantly higher among contemporary strains. Changes in the incidence and levels of antibiotic resistance are not confined to particular segments of the bacterial population and reflect responses to the increased exposure of bacteria to antimicrobial compounds over the past several decades.
Feedback to semi-professional counselors in treating child aggression

Abstract Objective: To investigate the impact of outcome feedback provided to semi-professional counselors of children and adolescents at risk for aggressive behavior, following group treatment. Method: Participants included 230 aggressive children and adolescents and 64 educators in a quasi-experimental design of 3 conditions: experimental group with feedback, experimental group without feedback, and control group (no treatment). The current study employed a feedback system based on self-report aggression scores measured after each session, provided to teachers, including an alert system and weekly follow-up group support. Results: Outcomes were more favorable for the treatment children than the control group, but feedback had no impact on the results. Conclusion: Outcome feedback provided to group therapists does not have an effect on children and adolescents' reduction of aggression. Further research is needed to identify possible reasons for failure to show feedback effect.
SVD iterative decision feedback demodulation and detection of coded space-time unitary differential modulation

A new suboptimal demodulator based on iterative decision feedback demodulation (DFD), and a singular value decomposition (SVD) for estimation of unitary matrices, is introduced. Noncoherent communication over the Rayleigh flat-fading channel with multiple transmit and receive antennas, where no channel state information (CSI) is available at the receiver is investigated. With four transmit antennas, codes achieving bit-error rate (BER) lower than 10/sup -4/ at bit energy over the noise spectral density ratio (E/sub b//N/sub o/) of -0.25 dB up to 3.5 dB, with coding rates of 1.6875 to 5.06 bits per channel use were found. The performance is compared to the mutual information upper bound of the capacity attaining isotropically random (IR) unitary transmit matrices. The codes achieve BER lower than 10/sup -4/ at E/sub b//N/sub o/ of 3.2 dB to 5.8 dB from this bound. System performance including the iterative DFD algorithm is compared to the one using Euclidean distance, as a reliability measure for demodulation . The DFD system presents a performance gain of up to 1.5 dB. Uncoded systems doing iterative DFD demodulation and idealized pilot sequence assisted modulation (PSAM) detection are compared. Iterative DFD introduces a gain of more than 1.2 dB. The coded system comprises a serial concatenation of turbo code and a unitary matrix differential modulation code. The receiver employs the high-performance coupled iterative decoding of the turbo code and the modulation code. Information-theoretic arguments are harnessed to form guidelines for code design and to evaluate performance of the iterative decoder.
Preliminary Results of a Phase I/II Study of Sodium Pentosanpolysulfate in the Treatment of Chronic Radiation‐Induced Proctitis

This is a report of a phase I/II study of 13 patients treated with sodium pentosanpolysulfate (PPS) for chronic radiation- induced proctitis. A complete response was obtained in 82%, a partial response occurred in 9%, and 9% failed to respond to therapy. No significant toxicity was observed. It is concluded that PPS is an effective treatment for chronic radiation- induced proctitis and a phase III randomized, double-blind study of PPS versus placebo is planned.
Down's Syndrome, Dementia, and Superoxide Dismutase

Mental handicap includes specific behavioural phenotypes apparently caused by single enzyme errors or deletions, for example, compulsive self-mutilation and hypoxanthine-guanine phosphoribosyl transferase deficiency in the Lesch-Nyham syndrome. In Down's syndrome, the possession of additional genetic material is found to be linked to various physical abnormalities (premature cataract formation and hypothyroidism). These close associations between types of behaviour, illnesses, and known genetic abnormalities offer promising avenues for research. In this article we concentrate on the well known link between Down's syndrome and presenile dementia.
Provider Advice on Exercise and Diet Among Adults With Comorbid Serious Psychological Distress and Diabetes or Diabetes Risk Factors

Purpose To examine the lifetime prevalence and correlates of provider advice to increase exercise and reduce dietary fat intake among adults with comorbid serious psychological distress (SPD) and diabetes or diabetes risk factors. Methods Study sample (n = 5942) was selected from the Medical Expenditure Panel Survey Household Component (MEPS-HC) series of 2007-2011. SPD was defined as a score of ≥13 on the Kessler Psychological Distress Scale (K6). Multivariate logistic regression was used to examine correlates of lifetime provider advice. Results Less than half of adults with SPD had been advised to increase exercise (49.4%) or reduce dietary fat intake (45.6%). The prevalence of receiving provider advice increased in a linear fashion as the number of diabetes risk factors increased and was the highest among those with diabetes. Provision of provider advice was strongly associated with clinical factors rather than individuals’ sociodemographic characteristics and current health behaviors. Conclusions Health care providers are missing opportunities to provide exercise and low-fat dietary advice to patients with SPD before they manifest clinical risk factors associated with diabetes. It is important that providers counsel them as early as possible about exercise and nutritional changes that reduce the risks associated with diabetes.
Performance of Acoustic Radiation Force Impulse imaging for the staging of liver fibrosis: a pooled meta‐analysis

Summary. Acoustic Radiation Force Impulse (ARFI) imaging is a novel ultrasound‐based elastography method that is integrated in a conventional ultrasound machine enabling the exact localization of measurement site. It might present an alternative method to transient elastography for the noninvasive assessment of liver fibrosis. At present, studies with small patient population have shown promising results. A systematic review and meta‐analysis of pooled patient data were performed to evaluate the overall performance of ARFI for the staging of liver fibrosis. Literature databases were searched up to 10/2010. The authors of the original publication were contacted, and the original patient data were requested. A meta‐analysis was performed using a random effect meta‐analytic method for diagnostic tests. In addition, available data comparing ARFI with FibroScan with the DeLong test were evaluated. Literature search yielded nine full‐paper publications evaluating ARFI while using liver biopsy as reference method. Original patient data were available from eight studies including 518 patients. The mean diagnostic accuracy of ARFI expressed as areas under ROC curves (AUROC) was 0.87 for the diagnosis of significant fibrosis (F ≥ 2), 0.91 for the diagnosis of severe fibrosis (F ≥ 3), and 0.93 for the diagnosis of cirrhosis. ARFI can be performed with good diagnostic accuracy for the noninvasive staging of liver fibrosis.
Assessment of safe bioactive doses of Foeniculum vulgare Mill. essential oil from Portugal

Abstract This study was designed to evaluate the antifungal activity of Foeniculum vulgare essential oil; concomitantly, the safety of bioactive doses was also unveiled, for the first time, in several mammalian cells. The chemical characterisation was made by GC and GC–MS. Antifungal activity was evaluated against yeasts, dermatophytes and Aspergillus strains and germ tube inhibition assay was evaluated using Candida albicans. Cell viability was assessed by the MTT assay. The main constituents of the oil are E-anetol (47%), α-phellandrene (11%), α-pinene (10.1%) and fenchone (10.8%). The oil was more active against Cryptococcus neoformans and C. albicans (MICs 0.32–0.64 μL/mL) and the filamentation of C. albicans was totally inhibited with 0.08 μL/mL. The oil is safe for keratinocytes, hepatocytes and fibroblasts in concentrations up to 1.25 μL/mL, and to macrophages up to 0.64 μL/mL. These findings highlight safe bioactive concentrations that should be deeper investigated for further application in pharmaceutical industry.
Toward a psychology of situations across cultures

The study of psychologically salient features of situations is a natural product of the confluence of personality and social psychology. Social psychology historically has focused on situational variables via experimental manipulation, while personality psychology has developed an array of tools for psychometric assessment, using correlational methods. Combine the two approaches, and the result is a number of modern research programs aiming to assess the psychologically meaningful aspects of situations. However, until recently the growing network of research on situations has barely begun exploring and comparing situations across cultures. Like the rest of psychology, as the study of situations accelerates, it also needs to extend its reach around the world. This chapter will examine how situational assessment has been conducted both within and across cultures, and some of the methodological and conceptual issues that surround the cross-cultural assessment of situations. Situation Assessment Every evening, someone in Italy is making pizza with a romantic partner; in Estonia, someone is taking a sauna with family members; in Canada, someone is drinking beer at a pig roast, and in Japan, someone is singing karaoke with colleagues after work. At the same time, people in all of these countries are watching TV, surfing the Internet, or eating dinner with family or friends 1 . All around the world, people experience a wide variety of situations, some of
