description: The trustworthiness of the blood pressure (BP) readings acquired by oscillometric home-based monitoring systems is a challenging issue that requires patients to see the doctor for trusted measurements, especially those who are obese or have cardiovascular diseases such as hypertension or atrial fibrillation. Even with the most accurate monitors one may get different readings if BP is repeatedly measured. Trusted BP readings are those measured with accurate devices at proper measurement conditions. The accurate monitors need an indicator to assure the trustworthiness of the measured BP. In this work, a novel algorithm called the Dynamic Threshold Algorithm (DTA) is proposed that calculates trusted boundaries of the measured systolic and diastolic pressures from the recorded oscillometric waveforms. The DTA determines a threshold from the heart rate of subjects to locate the oscillometric pulse at the mean arterial pressure (PULSEMAP) and uses the peak, trough, and pressure of the located pulse to calculate the trusted boundaries. In terms of accuracy, a modeling approach is employed to estimate BP from the arterial lumen area oscillations model in the diastolic region (ALA-based). The model requires compliance parameter ‘c’ to estimate BP. To this end, a pre-developed linear regression model between ‘c’ and the corresponding amplitude ratio of the PULSEMAP is employed to evaluate ‘c’. The proposed method uses ‘c’ and estimates BP by minimizing differences between peak and trough amplitudes of the actual and corresponding simulated waveforms. The proposed DTA and ALA-based methods were tested on two datasets of healthy subjects and one dataset of sick subjects with cardiovascular diseases, and results were validated against corresponding references and compared with two popular maximum amplitude and maximum/minimum slope algorithms. Mean absolute error (MAE) and standard deviation of errors (STDE) are used to evaluate and compare the results. For healthy subjects, the MAE of the estimated systolic (SBP) and diastolic (DBP) blood pressures was improved up to 57% and 57% with an STDE of 55% and 62%, respectively. For sick subjects, the MAE was improved up to 40% and 29% with an STDE of 36% and 20% for SBP and DBP, respectively.

Tobacco Control and Public Health in Eastern Europe 2 (Supplement 1, 2nd conference 'Economics, sociology, theory and practice of public health'):s45 OBJECTIVE(S): To investigate associations between alcohol drinking by parents at different time of their life and alcohol use by adolescents. DESIGN: The longitudinal epidemiological study design was used to answer the proposed research questions. This study is based on the data of the Family and Children of Ukraine Study (FCOU), which is a prospective cohort study of women and children. PARTICIPANTS: Recruited subjects were pregnant women with last menstrual period (LMP) between 25 December 1992 and 23 July 1994. Self-completed questionnaires and the medical record data were collected at the first antenatal clinic visit and at the delivery. The sample in the city of Dniprodzerzhynsk consists of 2148 women, their children and partners (if any), but at 15-17-years-old follow-up only data about 1020 participants were available. MAIN EXPOSURES: Use of alcohol by mother/father before pregnancy, during pregnancy, and at 15-17 years of child’s age. OUTCOME MEASURE: Use of alcohol by 15-17-year-old adolescent. RESULTS: Use of alcohol more than once a week by mother before pregnancy was associated with alcohol abuse by adolescents, unlike father’s use of alcohol before and during pregnancy. Use of alcohol both by mother and father during adolescence of their offspring was strongly associated with alcohol abuse by the child. In the multivariate analysis only alcohol use by mother during adolescence of the child was significantly associated with alcohol use by the adolescent. CONCLUSIONS: This study supports the hypothesis that concurrent social factors influence regular alcohol use among adolescents more intensively than early life factors.

description: This thesis addresses the issue of encoding and decoding still and time-varying stereoscopic imagery. A review of current encoding techniques is undertaken, with special emphasis on algorithms having SNR and spatial scalability. A stereo image pair consists of two views of the same scene. Due to the redundant nature of both views, prediction-based techniques produce superior results when compared with independent encoding of both images. Some of the most widely used embedded still-image coding techniques rely on discrete wavelet transform (DWT)-based analysis. However, these schemes cannot be adapted in a straightforward manner to encode stereoscopic still-image pairs. In this thesis, a novel DWT-based embedded stereoscopic still-image codec structure is proposed. This scheme preserves the progressive transmission capability of still-image coding algorithms, while suitably adapting to the nuances and special characteristics of stereoscopic imagery. A comparative study of variable-block and fixed-block disparity estimation is also undertaken. Partition artifacts result due to imperfect disparity compensation. Drawbacks in existing compensation techniques are discussed and a novel loop-filtering scheme is proposed. This is used to smooth disparity-compensated images before generating and subsequently encoding residual images. As seen from this thesis, this scheme improves on the performance of current techniques. In addition, the dyadic sampling structure of a 2-D DWT is exploited to obtain discrete levels of spatial-scalability and forms part of an embedded scheme for transmission of stereoscopic still-images at different spatial resolutions. The proposed algorithm is suitably modified to encode time-varying stereoscopic imagery. Drawbacks of current moving-picture hierarchies are analyzed and a novel hierarchy is proposed that insures that a user has the flexibility to view a sequence either in monoscopic (default) or stereoscopic modes. Independent objective results, explaining SNR and spatial scalability features, are presented when encoding a few pictures of a stereoscopic moving image sequence. In addition, informal subjective results are presented when viewing encoded versions a time-varying sequence.

description: Background. Huntington disease (HD) is an adult onset neurodegenerative disorder caused by a polyglutamine expansion in the huntingtin (htt) protein. Htt function is essential for embryonic survival as well as normal function during the postnatal period. In addition to having roles in transcription and transport, recent evidence demonstrates that wild-type htt is neuroprotective in vivo. To determine whether treatment with wild-type htt would be beneficial in HD, we crossed the YAC128 mouse model of HD with mice that over-express wild-type htt (YAC18 mice) to generate YAC128 mice that over-express wild-type htt (YAC18/128 mice). Results YAC18/128 mice were found to express mutant htt at the same level as YAC128 mice and wild-type htt at the same level as YAC18 mice. YAC18/128 mice show no significant behavioural improvement compared to YAC128 mice in the rotarod test of motor coordination or in an automated open field test. In the brain, YAC18/128 mice show no significant improvement in striatal volume, striatal neuronal numbers or striatal DARPP-32 expression compared to YAC128 mice. In contrast, striatal neuronal cross-sectional area showed significant improvement in YAC18/128 mice compared to YAC128 mice. Conclusion While the over-expression of wild-type htt results in a mild improvement in striatal neuropathology in YAC128 mice, our findings suggest that treatment with wild-type htt may not be sufficient to ameliorate the symptoms of HD in this model.

Tobacco Control and Public Health in Eastern Europe 2 (Supplement 1, 2nd conference 'Economics, sociology, theory and practice of public health'):s33-s34 BACKGROUND: Integrated biobehavioral surveys (IBBS) have been used to evaluate the impact of HIV prevention efforts among most-at-risk groups in Ukraine since 2007. Harm reduction program coverage among injecting-drug users (IDUs) increased substantially from 96,000 in 2008 to 170,000 in 2010 with support from the Global Fund, and IBBS have shown declining HIV prevalence. Aim of the study was to examine the changes in HIV prevalence, drug use patterns and risky behaviors in IDUs on national and city level. METHODS: For this analysis, three IDU-IBBS datasets were combined – 2008 (N=3711), 2009 (N=3962), and 2011 (N=9069). The analysis included 25 cities that participated in either 2008 or 2009, and 2011. Changes in HIV prevalence, drug use, and risk behaviors were compared between 2008/9 and 2011. RESULTS: The surveyed IDU population in 2011 was older than in 2008/9 (31.0 vs. 32.8 years; p Overall HIV prevalence in the sample declined slightly (22.9% to 21.6%; p=.05). In eight cities, HIV prevalence decreased significantly (-5% to -18%), while significant increases were seen in five cities (8% to 15%). Prevalence among IDUs younger than 25 years declined (9.9% to 7.2%; p=.0078). The combined dataset showed no difference in opioid or stimulant past-30-day use, with variation at city level. Clean needle/syringe use during last injection increased significantly (88.8% to 97.0%; p CONCLUSIONS: IDUs in Ukraine are ageing and HIV seroprevalence among IDUs continues to decline, especially among young IDUs. However, prevention programming needs to respond to significant regional variations in risk behaviors and HIV transmission. HIV, prevalence, IDU, biobehavioral surveys

Conference abstract Legislative background of food and nutrition policy in Ukraine
Chagarna, Natalia; Andreeva, Tatiana  BACKGROUND: The importance of effective policy aimed at improving nutrition practices is highly recognized by the global community.
METHODS: Analysis of Ukrainian legislative documents was conducted to clarify the situation in the field of policy initiatives and legislation devoted to nutrition in Ukraine. Documents in force adopted from 1991 to 2011 including key words “nutrition”, “health”, “concept”, and “food products” were reviewed.
RESULTS: We reviewed 55 legislative acts related to nutrition and identified several groups: 18 documents are related to organization of supply, regimen, norms of nutrition in state establishments or for special populations; 12 documents related to economic and technological regulation of food preparation, quality control and distribution; 3 documents regulating nutritious and safety norms of food products for children under 3 years; 14 documents aimed to control food safety, quality and accessibility; 6 other documents partly referred to nutrition, including 4 Concepts of healthy lifestyles. Some of the principles of healthy eating are declared in the “Concept of improving food security and quality of nutrition of the population” approved by the Cabinet of Ministers in 2004. Principles of maintaining breastfeeding, activities aimed to reduce iodine deficiency among population as well as school educational program “Foundations of health” were those few governmental activities, which supported some of the ideas declared in the Concept.
CONCLUSION: Great attention of policymakers is paid to regulation of production, distribution of food, its quality control, affordability of products for special population groups, especially children. Not much attention is devoted in the official documents to creating and maintaining the healthy eating practices of the population. Mechanisms aimed to form healthy eating practices are not specified in the legislative documents. No regulatory documents to implement these principles were found. The existing regulatory documents do not fully reflect global trends and practices for healthy eating.

Feature selection with a general hybrid algorithm

Subjects: subject: Computer Science.

description: The Feature Selection problem involves discovering a subset of features, such that a classifier built only with this subset would have better predictive accuracy than a classifier built from the entire set of features. A large number of algorithms have already been proposed for the feature selection problem. Although significantly different with regards to (1) the search strategy they use to determine the right subset of features and (2) how each subset is evaluated, feature selection algorithms are usually classified in three general groups: Filters, Wrappers and Hybrid solutions. In this thesis, we propose a new hybrid system for the problem of feature selection in machine learning. The idea behind this new algorithm, FortalFS, is to extract and combine the best characteristics of filters and wrappers in one algorithm. FortalFS uses results from another feature selection system as a starting point in the search through subsets of features that are evaluated by a machine learning algorithm. With an efficient search heuristic, we can decrease the number of subsets of features to be evaluated by the learning algorithm, consequently decreasing computational effort and still be able to select an accurate subset. We have also designed a variant of the original algorithm in the attempt to work with feature weighting algorithm. In order to evaluate this new algorithm, a number of experiments were run and the results compared to well-known feature selection filter and wrapper algorithms, such as Focus, Relief, LVF, and others. Such experiments were run aver a number of datasets from the UCI Repository. Results showed that FortalFS outperforms most of the algorithms significantly. However, it presents time-consuming performance similar to that of wrappers. Additional experiments using specially designed artificial datasets demonstrated that FortalFS is able to identify and remove both irrelevant, redundant and randomly class-correlated features. The FortalFS time-consumption issue is addressed through parallelism. A parallel version of FortalFS based on the master/slave design pattern is implemented and evaluated. In several experiments, we were able to achieve near optimal speedups.

description: Background: In countries with low hepatitis A (HA) endemicity, infected food handlers are the source of most reported foodborne outbreaks. In Canada, accessible data repositories of infected food handler incidents are not available. We undertook a systematic review of such incidents to evaluate the extent of viral transmission through food contamination and the scope of post-exposure prophylaxis (PEP) interventions. Methods: A systematic search of MEDLINE and EMBASE was conducted to identify published reports of incidents in Canada. An expanded search of a news repository (i.e., transcripts from newspapers and newscasts) was also conducted to identify the location and timing of an incident, which was used to retrieve the related report by contacting local public health departments. Data pertaining to case identification, public health risk, PEP interventions, and associated costs was independently abstracted by two reviewers and summarized according to incidents with and without large PEP interventions. Results: A total of 16 incidents were identified from 1998–2004. There were approximately 3 incidents requiring public notification per year. Only 12.5% of incidents were described in published reports, indicating that published data significantly underestimated the number of incidents and PEP interventions. Data pertaining to the remaining incidents was unpublished, sparse and highly dispersed at the local public health level. Six of the 16 incidents required large PEP interventions to immunize on average 5000 potentially exposed individuals. Secondary transmission was low. Characteristics of incidents requiring large PEP interventions included potentially infectious food handlers working with uncooked food for a prolonged duration in high-volume grocery stores in high-density urban areas. Conclusion: Infected food handlers with hepatitis A virus (HAV) requiring public notification are not infrequent in Canada. Published data severely underestimated the burden of PEP intervention. Better and consistent reporting at the local and national level as well as a national data repository should be considered for the management of future incidents.

description: Les inegalites sociales de sante ont ete denoncees a maintes reprises par des etudes en sante publique. Plusieurs d'entre elles ont permis d'identifie les taux de morbidite et de mortalite tres eleves des hommes issus de milieux socioeconomiquement defavorises. Par exemple, au Canada, cette sous-population souffre 3,4 fois plus de maladies cardiovasculaires que son homologue plus aise et, malgre les avances medicales, elle est plus a risque de succomber a cette maladie. Ce type d'inegalites a ete explique en partie par la variation sociale des styles de vie entre les classes sociales. Cette etude porte sur les pratiques des hommes socioeconomiquement defavorises (SED) en contexte de readaptation cardiaque. Elle identifie les mecanismes sociaux explicatifs des styles de vie des hommes SED ayant subit des MCV dans le but d'ameliorer les connaissances en promotion de la sante. L'etude emploie la theorie socioculturelle de Pierre Bourdieu afm, d'une part, de comprendre leurs conceptions du corps, de la sante et de la maladie pour identifier leurs strategies, s'il y a lieu, pour maintenir et ameliorer leur sante et, d'autre part, de saisir leur perception des ressources materielles et humaines necessaires a l'adhesion a un regime de sante. Les resultats reposent sur une analyse qualitative d'entrevues menees aupres de vingt hommes ayant souffert d'une maladie cardiovasculaire. Ils indiquent que, de maniere generale, la defavorisation materielle et sociale de ce groupe faconne un rapport au corps qui est peu propice a l'adoption d'un regime de sante. Une analyse plus fine est presentee a l'interieur de deux articles scientifiques. Le premier article presente la hierarchie des pratiques des participants et le deuxieme permet de souligner davantage les effets du fatalisme et du rapport au temps a court terme sur leurs styles de vie. L'etude conclut qu'il est souhaitable que des politiques qui cherchent a reduire les inegalites sociales soient mises en place afin de permettre aux populations SED d'avoir acces a des conditions de vie plus adequates; necessaires a l'adoption d'un regime de sante recommande par les acteurs en sante publique.

Bondarenko, Kseniia; Danyliv, Andriy BACKGROUND: People living with diabetes (PLD) have special needs which could be effectively and efficiently addressed at the stage of pharmaceutical care. We analyzed preferences of PLD in Kyiv for services that could be potentially implemented in a specialized pharmacy.
METHODS: We used a discrete choice experiment (DCE) to elicit preferences for pharmacist’s consultation, possibility of testing, and the availability of special products. The pharmacy was described with 3 attributes having 2 levels and 2 attributes having 3 levels. The analysis is based on interviews with 98 PLD. Respondents were recruited either in the in-patient unit of Kyiv endocrinology center or through snow-ball approach between January 2012 and March 2012. The DCE part consisted of 12 choice tasks (orthogonal fractional factorial design). To reduce the number of choices per respondent, the DCE was split into two experiments of 6 choices each. Respondents were randomly assigned to either DCE. Logistic regression xtlogit was used to model DCE responses using STATA version 11.0.
RESULTS: Pharmacist’s consultation regarding the use of drugs, their compatibility, and special diet was the most important choice factor among PLD (marginal willingness to pay (MWTP) was 23.38 UAH), followed by the possibility of controlling the blood pressure, blood sugar and cholesterol levels, (MWTP is 21.68 UAH) and the availability of specialized products (MWTP is 13.57 UAH). Time for purchase (including travel and waiting) did not significantly affect the choice of pharmacy.
CONCLUSIONS: Respondents gave mostly meaningful answers to the DCE and the model is theoretically valid. PLD are willing to spend time on traveling to the specialized pharmacy with Good Pharmacy Practice services. Conclusively, introduction of the pharmacy with special focus on PLD has good potential in Kyiv as they are ready to spend additional time and money to obtain proper services.

Conference abstract Condom use with different types of sexual partners in Ukraine: results of 2007 survey
Barska, Julia BACKGROUND: Use of condoms is recommended in all risky sexual contacts, as long as a couple becomes monogamous and tests for HIV and other STDs. This research aims to examine whether people in Ukraine follow this recommendation.
MATERIAL AND METHODS: Associations between condom use at last sexual intercourse and type of sexual partner were explored separately for men and women based on data of 2007 survey by using regression models adjusted for knowledge about and attitude to STDs and HIV, contraception and pregnancy, risky behaviour and socio-demographic characteristics.
RESULTS: Generally, 37.2% of men and 25.2% of women reported using condom at last sexual contact. Overall, use of condoms increased with less intimacy between partners: 22.6% of men and 19.2% of women used condoms with their spouses, 62.8% and 52.4% ― with girl-/boy-friends, somewhat less – 56.6% and 35.3% ― with casual acquaintance, respectively, and 71.4% of men – with commercial sex workers; in multivariate analysis direction of associations remained the same. Moreover, risky sexual behaviour for both genders, and drugs ever-use and alcohol consumption during last sex for men reduces odds of using condoms. Also, men demonstrating correct knowledge of ways of horizontal transmission of HIV and women aware about ways of prevention of HIV transmission had higher odds of using condoms, as well as women confident in their ability to buy condoms. For socio-demographic characteristics, having children, younger age and dwelling in non-Western regions and cities were positively associated with using condoms.
DISCUSSION AND CONCLUSIONS: Although condom use in Ukraine is not prevalent enough, there is a tendency to more frequent use of them with high-risk sexual partners. At the same time, people practicing other types of risky behaviour use condoms less, too.

description: The use of agribusiness residual lignocellulosic fibres can be a good alternative in the development of lignocellulosic composites. The current work aimed to investigate the thermal performance of cement-based composites with lignocellulosic materials: Eucalyptus, sugarcane bagasse, coconut fibre in comparison with commercial gypsum board to be used as internal partitions of the building using infrared thermal images. Three repetitions for each kind of lignocellulosic material were made, and three commercial gypsum boards were used. In the production of the panels, the following parameters were applied: material and cement ratio, 1:2.75; water and cement ratio, 1:2.5; hydration water rate of 0.25; additive, 4% (based on cement mass). The calculations were performed for a nominal panel density of 1,200 kg m- ³. The thermal analysis was performed in a chamber composed of MDP (Medium-Density Particleboard) and with an internal layer of rock wool and the heat source (thermal resistance). For the superficial temperature measurement, a FLIR E75 camera was used to capture the infrared images. When the internal temperature of the chamber stabilized at 50 °C, an infrared thermal image was collected from each side of the composite. Thermal properties were analysed: thermal conductivity, resistivity, resistance, and transmittance. Based on the results, sugar cane cement composites were characterized by higher values of thermal conductivity. Related to thermal resistivity, thermal resistance, and thermal transmittance, only the coconut panel presented similar behaviour to the commercial gypsum board. Thus, cement composite using coconut can be a potential alternative that might solve energy and environmental concerns simultaneously.

description: Baranovska A, Doroshenko O (2012) Estimation of the scope and the cost of services for treating tuberculosis for Vinnitsa region. Tobacco Control and Public Health in Eastern Europe 2 (Supplement 1, 2nd conference 'Economics, sociology, theory and practice of public health'):s29-s30 BACKGROUND: Great resources aimed at combating TB are allocated in Ukraine, but the cost of the TB case is not clearly estimated for the country and service provider. So, the aim was to calculate cost of the TB services according to hospital expenditure and Protocol for treating TB patients.
METHODS: Data collection was conducted in Vinnitsa region TB clinic and Vinnitsa TB clinic №2. Data for the method of step method of cost sharing were collected by analyzing the documents (financial and statistical reports). The cost of different courses of TB treatment was estimated for different groups of patients according to schemes previously constructed through analyzing the Protocol and medical records of the patients.
RESULTS: The actual cost of daily stay of in-patients is estimated as 131 UAH (patient of the 1st category), 156 UAH (2nd category), 184 UAH (MRTB). The monthly cost of outpatient treatment was calculated as 102 UAH (patients of the 1st and 2nd category). If the clinics follow the Protocol for the treatment of TB patients the total costs for treating the patient of the 1st category mounts 8,773-12,906 UAH (inpatient stay 7,872-11,088 UAH, medicine 237.8 UAH, laboratory tests 307.05 UAH, X-rays 61.68 UAH, outpatient care 491.5 UAH), for 2nd category – 15,508 – 15,606 UAH (inpatient stay 14,103 UAH, medicine 237.8 UAH, laboratory tests 229.6 UAH, X-rays 61.68 UAH, outpatient care 589.8 UAH ) and for MRTB – 1,025,992 UAH (inpatient stay 99,619 UAH, medicine 28,666 UAH, laboratory tests 311 UAH, X-rays 123.4 UAH).
CONCLUSION: Cost for inpatient stay and medicine take the major part in cost structure, causing the differences for categories. Calculation of the cost for TB case would be helpful for the effective distribution of resources, based on the costs of the treatment for different categories.

description: Increasing awareness of the value of home literacy experiences, combined with a recognition of the importance of the family, has contributed to growth in the number of family literacy programs. These, however, lack theoretical underpinnings. Further, there is a paucity of studies in family literacy practices with school age children. This study uncovers the interplay of family literacy practices in one low-income neighbourhood. To address sociocultural factors that affect literacy, societal circumstances and issues which enable or constrain literacy events were explored. By entering into the life-worlds of participants to portray lived dimensions of enculturation and family literacy this study employs critical theory to expand research in family literacy. The following questions guided my inquiry into the literacy-related practices and perceptions of low-income families: how family literacy practices unfold, how literacy is embedded in the social practices and relationships between school and home, and what conditions and factors within the family contribute to family literacy practices and children's enculturation into these practices? Eight families were purposively selected for this exploratory case study. Data collection included observations at school, parent interviews, questionnaires, journal entries, parent-child interactions and field notes. The findings uncover the ways that low-income families use and perceive literacy in their homes and serve to challenge assumptions, namely that we live in an egalitarian society and that schools do not privilege particular ways of thinking. The tragedy of living in poverty with its inherent barriers to equitable access and participation is presented as a key factor in limiting educational opportunities for low-income children. Emergent themes include: conflicting time orientation of low-income families; cultural mismatch between teachers and students; importance of the social environment and families as powerful social conduits for culture and identity formation; and limitation in household resources to support educational pursuits. These were analyzed for discourses of hope, invasion, time, space, female body and maternity that they frame in the women's lives. Implications for shaping current practice, future research, teacher education, and public policy are discussed. The significance of this study for the family literacy field inheres in offering an interactive model of literacy practices for educators.

Tobacco Control and Public Health in Eastern Europe 2(Supplement 1, 2nd conference 'Economics, sociology, theory and practice of public health'): s51. BACKGROUND: Waterpipe smoking becomes a public health problem in countries where it is brought from the Middle East. The objective was to compare prevalence of waterpipe smoking among university students (WSAUS) in two countries of the former Soviet Union – Russia and Ukraine – with countries with traditional use of waterpipe and those where it has recently arisen.
METHODS: A systematic review of research of WSAUS was conducted with the use of PubMed. Survey of Kyiv-Mohyla Academy students (Kiev, Ukraine) was conducted in 2007-2009 and of Kazan medical university (Kazan, Russia) in 2010.
RESULTS: Nineteen studies of WSAUS were revealed. Daily WSAUS was only addresses in four studies and varied from about 1% in Lebanon and Pakistan to 7% in men in Syria. Prevalence of daily smoking in Russia (0.6%) did not exceed that. Current smoking varied greatly: 5.6-35.0% for all, 14.6-49.6% for males, 4.9-20.2% for females. Last week WSAUS varied from 3.3% in Pakistan to 9.3 in Lebanon. Measurements in Russia (3.5%) fall into this interval. Last month WSAUS varied from 9.5% to 20% in Iran, Pakistan, and USA with 13-14% measured in Russia and Ukraine. Last year WSAUS was between 18.7% in Pakistan and 30.6% in USA. Measurements in Kiev (39.7%) and Kazan (52.3%) were much higher. Ever smoking of waterpipe was 37.9% in UK, 53.6% in Pakistan, and somewhat higher in Russia and Ukraine.
CONCLUSIONS: Comparison of period prevalence indicators in selected universities of Ukraine and Russia shows that daily, weekly, monthly prevalence indicators are similar to those in countries with traditional use of waterpipe. Last year and life time smoking indicators in Russia and Ukraine are higher than those in countries with traditional and newly established waterpipe use. To measure prevalence of waterpipe smoking questions with clearly specified time spans (day, week, month, year, lifetime) are needed.

description: Abstract: - Human Organ transplants is now a fully grown discourse in the practice of medicine and health where by apart from medical doctors (physicians and surgeons), nurses and health practitioners, religious leaders be it pastors and Imams have had many opinions that bothers on ethical considerations about such an indispensable, innovative surgical life procedure that restores the human life and human existence.

Organ transplant has been in existence since 1954 when, after numerous unsuccessful previous attempts, the first successful kidney transplantation by Murray et al. made human allotransplantation.

Allotransplantation is the transplantation of an organ or tissue from one individual to another of the same species Organ transplantation is the modern way of prolonging life of people suffering from end stage organ diseases worldwide. The most known ones are the hepatic and renal transplants (Liver and Kidney). The main root of organ donations in Ghana are from living donors. Organ donations from the dead have far been advanced with ethical considerations and legal inputs.

Is a known fact that a few number of organs come from living brain dead donors in Africa and Ghana is not an exception.

Yet, despite the surgical and medical advancement, the scarcity of human organs for transplantation has become a medical task and an albatross that has taken both clinical, religious, political and academic hiatus yet to be repaired by all stakeholders involved in it.

The field of human organ transplantation is complicated as it details more on ethical, religious and psychosocial issues.

There are many successes, problems and controversies surrounding organ donation, harvesting and transplantation.

The worse approach are human organ trafficking, the buying and selling of organs from what is known as brokers.

In Ghana most of the organ donations are from living donors and the percentage of cadaveric organ donation is low.

There is no explicit consent and presumed consent systems in Ghana yet. Ethically, there can be  little or no harm to living organ donors. The availability of a matched donor is a high issue in Ghana coupled with religious, psychosocial influence and financial inability to embark on organ transplant procedures. some of the very well documented factors in organ transplantation are the religious, legal, ethical and surgical/medical paradigms in country wide.

description: Background: User-scripts are programs stored in Web browsers that can manipulate the content of websites prior to display in the browser. They provide a novel mechanism by which users can conveniently gain increased control over the content and the display of the information presented to them on the Web. As the Web is the primary medium by which scientists retrieve biological information, any improvements in the mechanisms that govern the utility or accessibility of this information may have profound effects. GreaseMonkey is a Mozilla Firefox extension that facilitates the development and deployment of user-scripts for the Firefox web-browser. We utilize this to enhance the content and the presentation of the iHOP (information Hyperlinked Over Proteins) website. Results: The iHOPerator is a GreaseMonkey user-script that augments the gene-centred pages on iHOP by providing a compact, configurable visualization of the defining information for each gene and by enabling additional data, such as biochemical pathway diagrams, to be collected automatically from third party resources and displayed in the same browsing context. Conclusion: This open-source script provides an extension to the iHOP website, demonstrating how user-scripts can personalize and enhance the Web browsing experience in a relevant biological setting. The novel, user-driven controls over the content and the display of Web resources made possible by user-scripts, such as the iHOPerator, herald the beginning of a transition from a resource-centric to a user-centric Web experience. We believe that this transition is a necessary step in the development of Web technology that will eventually result in profound improvements in the way life scientists interact with information.
