Sleep apnea and other sleeping disorders impair health and quality of life. Polysomnography is the primary method for diagnosis, but involves cost and utilization of medical resources, which limit access for potential patients. The clinical environment and sensors of polysomnography hinder typical sleep patterns in many individuals, thus degrading the analysis. Sensors suitable for at-home monitoring of sleep have recently become available. At-home monitoring of sleep may improve diagnosis due to increased familiarity for sleeping and ability for multiple sleep sessions, as well as lowering the cost. However, more robust algorithms would be needed to partially compensate for the less controlled conditions and sensor systems. A mat with a grid of force sensors has become available. This study was developing a state machine algorithm to analyze the activity at multiple force sensors of a mat while the subject was lying in supine position on the mat and undertaking natural, rhythmic respiration. The algorithm monitored the subset of active sensors to detect potential respiratory cycles. The similarity of the timing of the detected cycles between different sensors was used to determine the overall pattern of respiratory activity for the subject. Reliable detection of timing for respiratory cycles would be useful for detection of sleep apnea events.

The article looks at the different factors that go into the subject of buying food products in Morocco. The latter, is undergoing a food transformation affecting the urban and rural environment. The recent changes in the choice of purchasing products by Moroccan citizens have created in the country a favorable framework for the development of territorial products. This is a descriptive study based on a questionnaire and conducted over a period of 2 months, subjects with a sample size of 180 respondents are randomly recruited on social networks. The results show that consumers are now interested in where they buy food, the quality of the products and the cost/quality ratio in these places. This study also states that despite the importance of product price to the consumer, quality is the factor most sought after by the consumer. This leads to an obligation on the part of consumers to industrialists to integrate food products with high nutritional values and to use ingredients that do not cause a danger to human health.

Relevance. The most important influence on the yield, the timing of growing vegetables in greenhouses and the cost of the resulting crop, in addition to the arrival of solar radiation, is exerted by the presence of a system of artificial lighting in greenhouses and its capacity.It is no exaggeration to say that today artificial lighting in greenhouses is more effective than natural lighting. So, to obtain one kilogram of vegetables using artificial lighting, it is necessary to spend 4.5-5.0 thousand J/cm2, and in the case of natural lighting: 5.0-6.5 thousand J/cm2. This is due to the fact that when using artificial lighting in the greenhouse, we create the most comfortable growing conditions for the plants. Of course, every culture, every hybrid requires its own illumination parameters, so you should not try to formulate what the ideal artificial lighting will be. Proper lighting means getting the maximum yield from your crops at the lowest cost. An increase in the productivity of plants when grown under photoculture conditions occurs not only due to an increase in the lighting power per unit area of greenhouses, but also due to correctly selected hybrids. The cultivated hybrid is one of the most important criteria for both increasing its productivity and improving the quality of the fruit. But not all tomato hybrids recommended by breeding companies for growing under artificial lighting are ideal for such conditions.Methods. The methods used in agronomic science were used. The information base of the research was made up of reference materials from specialized publications on the subject under study (catalogs of breeding companies); materials received from participants in the greenhouse vegetable market (breeding companies, greenhouse plants); own research, articles and reviews in specialized journals.Results. Correctly selected tomato hybrids provide a significant increase in productivity in greenhouses, an improvement in fruit quality and a balanced cultivation technology under these conditions. An assortment of recommended tomato hybrids for growing in photoculture conditions is presented, an analysis of their advantages and disadvantages is made, and the main requirements for hybrids for these conditions are formulated.

Flowers, ornamental plants, planting material (saplings) and other plants with regard to which the market with possibility of carrying out independent adequate marketing was formed, are the subject of evaluation by the experts in field of forensic merchandising. With the development of the market and market relations such goods as flowers, planting material and others are increasingly encashed in the market of Ukraine and become the objects of forensic merchandising examinations and expert researches. Special feature of merchandising researches of the plant origin objects is the use of the comprehensive approach to the estimation of their quality and cost. Researches are carried out with the purpose of determination of properties, consumer value, conformity to standards and specifications of plants certain kinds. When studying a considerable variety of flower plants, one distinguishes scientific and industrial classifications. In merchandising flowers industrial classification of flower ornamental plants which provides distribution of flower plants to the separate groups similar on biological properties, the agricultural technician of cultivation and practical application in gardening is used. During carrying out merchandising examinations on an establishment of consumer properties of certain kinds plants, namely establishments organoleptic indicators of quality and quantity of flower decorative production given for research, the expert checks conformity of this production to requirements of normative and technical documents. Requirements to quality of flower production are normalised by standards depending on production kind – cutf lowers, pottery blossoming plants, pottery decorative sheet plants, sprouts of flower decorative production, planting material, seeds of flower ornamental plants. At carrying out merchandising researches of flower decorative production, plants and saplings it’s necessary for merchandising experts to pay special attention on definition of quality indicators and a grade of plants according to standards, and also to consider data concerning age of a plant, novelty of a grade and origin country of production.

We compared the cost of passive sensor telemedical non-stress cardiotocography performed at home and the same test performed by traditional equipment in an outpatient clinic in the Budapest area. The costs were calculated using two years’ registered budget data from the home monitoring service in Budapest and the outpatient clinic of the department of obstetrics and gynaecology at the Haynal Imre University of Health Sciences. The traditional test at the university outpatient clinic cost 3652 forint for the health-care and 1000 forint in additional expenses for the patient (travel and time off work). This means that the total cost for each test in the clinic was 4652 forint. The cost of home telemedical cardiotocography was 1500 forint per test, but each test took 2.1 times as long. For a more realistic comparison between the two methods, we adjusted the cost to take account of the extra length of time that home monitoring required. The adjusted cost for home care was 3150 forint, some 32% lower than in the clinic. Passive sensor telemedical non-stress cardiotocography at home was therefore less expensive than the same test performed in the traditional way in an outpatient clinic.

Background: Financial toxicity (FT) has been consistently demonstrated to a be a major contributor to morbidity and mortality in a variety of cancers. However, the vast majority of research examining this issue has been in solid tumors, and there has been less investigation of how this concept applies in malignant hematology and even fewer studies looking at an interventional model. This pilot study attempts to identify patients at high-risk due to FT in a busy clinical environment and improve clinical outcomes with comprehensive intervention. Methods: All patients seen at the Malignant Hematology Clinic at the Levine Cancer Institute, a tertiary hospital-based specialty practice, were surveyed at their visits over a six-month period. All patients were aged ≥18 years and diagnosed with hematologic malignancy or bone marrow failure syndrome. The survey consisted of the PROMIS Global-10 measure and two questions from the COST measure. FT was defined as scoring 5 or less (maximum: 10) in agreement with the COST questions: "I know that I have enough money in savings, retirement, or assets to cover the costs of my treatment" and "I am satisfied with my current financial situation." Patients with FT were entered into the interventional cohort and scheduled for a visit with a nurse navigator where they completed a standardized worksheet to identify gaps in care and opportunities for grant funding/other assistance. Patients were seen by a clinical pharmacist for copay review and discussion of assistance programs. Finally, patients were offered the services of a community pro-bono financial planner for help with budgeting, asset management, and general financial advice. Patients were tracked longitudinally for assistance provided, changes in PROMIS scores, and clinical outcomes. Categorical variables, including responses to survey questions, were summarized with frequencies and proportions, while continuous variables were summarized with medians and ranges. Correlation of FT screening scores and COST scores was assessed with Spearman's correlation. Baseline versus post-intervention PROMIS scores were compared with paired t-tests, while McNemar tests for agreement were used to compare ER and IP utilization 3 months prior versus post intervention. Results: A total of 107 patients were included in the intervention. Specific characteristics of the intervention population are listed in Table 1. FT screening scores were found to correlate with the full COST measure (Spearman correlation = 0.45, p <.001). Patients in the intervention cohort had high rates of noncompliance due to inability to afford prescription medications (16.8%), OTC medications (15.9%), and doctor visits (6.5%). In order to pay for their care, patients reported reducing spending on food and clothing (48.6%), using savings to cover OOP expenses (51.4%), and partially filling prescriptions (11.2%) (Table 2). In terms of the intervention, 37.4% of patients were found to qualify for and were helped to obtain grants from external foundations. The median value of these grants was $850 (range: $100-$17,850). Through manufacturer's assistance and other programs, the clinical pharmacy team was able to obtain free or greatly reduced cost medications for the qualified patients at a median retail value of $197,158 (range: $29,909-$639,801). Gas cards, food pantry assistance, and transportation assistance were also supplied to patients who qualified at a median value of $300 ($100-$300). 58 patients (54.2%) expressed interest and were scheduled with a pro-bono financial counselor. The intervention resulted in statistically significantly higher quality of life when measured by PROMIS physical and mental health scores, compared to baseline scores (Table 3) (all p <.001). There was no significant difference found when looking at patients with at least one ER visit 3 months prior and post intervention (10.3% vs 6.5% p=.317). There was no difference between inpatient visits/days pre and post intervention. Conclusions: Using a quick screening method for FT in a busy clinical environment is feasible and allows identification of an extremely high-risk population. Intervening on FT in a comprehensive way including navigators, pharmacists, and financial counselors is effective and leads to increased quality of life.

Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease worldwide, affecting more than four million people. Typically, it affects individuals above 45, when they are still productive, compromising both aging and quality of life. Therefore, the cost of the disease must be identified, so that the use of resources can be rational and efficient. Additionally, in Brazil, there is a lack of research on the costs of neurodegenerative diseases, such as PD, a gap addressed in this study. This systematic review critically addresses the various methodologies used in original research around the world in the last decade on the subject, showing that costs are hardly comparable. Nonetheless, the economic and social impacts are implicit, and important information for public health agents is provided.

Objective. Obstructive sleep apnea is a common problem, requiring expensive in-lab polysomnography for proper diagnosis. Home monitoring can provide an alternative to in-lab testing for a subset of OSA patients. The objective of this project was to investigate the effect of incorporating home testing into an OSA program at a large, tertiary sleep disorders centre.Methods. The Sleep Disorders Centre in Saskatoon, Canada, has been incorporating at-home testing into their diagnostic pathways since 2006. Administrative data from 2007 to 2013 were extracted (10030 patients) and the flow of patients through the program was followed from diagnosis to treatment. Costs were estimated using 2014 pricing and were stratified by disease attributes and sensitivity analysis was applied.Results. The overall costs per patient were $627.40, with $419.20 for at-home testing and $746.20 for in-lab testing. The cost of home management would rise to $515 if all negative tests were required to be confirmed by an in-lab PSG.Discussion. Our review suggests that at-home testing can be cost-effective alternative to in-lab testing when applied to the correct population, specifically, those with a high pretest probability of obstructive sleep apnea and an absence of significant comorbidities.

Abstract Sleep disorders impair the quality of life for many individuals, but often go undiagnosed and untreated due to the cost and sleep-disturbing aggravation of polysomnography, the clinical sleep test. Simpler sleep monitoring systems that could be used at home may provide useful health information. A 2D grid of force sensors within a mat beneath the thorax of a sleeping subject has been reported to enable monitoring of respiration during sleep. A physical model of a thorax over such a 2D grid of force sensors may enable more tests and perturbations of parameters than could be done using only human subjects. The purpose of this project was to develop and test a physical model of a thorax undergoing volume changes, and measuring the changes in force by a grid of force sensors under the model. A prototype system was developed. Early testing shows promise for being able to monitor the changes in force as volume of the model changes. More development and testing are required toward development of improved algorithms and systems for sleep monitoring mats.

The aim of this article is to provide an overview of university students’ experiences of online learning, based both on some previous empirical studies and literature during the last decade. Online education has become widespread in many countries during recent years, and the paradigmatic shift from traditional to online education (e.g., Harasim, 2000; Karuppan, 2001) has occurred as part of planned educational policy, with both international and national experiences supporting its growth. Similarly, students now have increasingly higher expectations regarding the quality of learning, and they expect a more individual, flexible, and humanistic approach in education. Students are increasingly demanding online access and universities are working to meet these demands (e.g., Song, Singleton, Hill, & Hwa Koh, 2004). In addition, technology is expected to improve access to education, reduce costs, improve the cost-effectiveness of education, and maintain the competitive advantage in student recruitment in higher education (Katz & Yablon, 2003; Newton, 2003). It is also important to note that no consistent paradigm for online education exists; rather there are multiple ways of making use of the Web in education, and these will vary for many reasons, for example, the needs of the learner and the subject being taught.
