Abstract:
Respiratory viral testing in hospitalized patients is thought to improve quality of care by reducing the use of diagnostic tests, guiding infection control precautions, and rationalizing antimicrobial therapies. Few small published studies have tested these assumptions, and have demonstrated conflicting results. We conducted a retrospective cohort study of 24,567 hospitalizations using administrative data to determine the associations between viral testing, patient outcomes, and process of care. Viral testing was not associated with improved mortality or length of stay in hospital, and resulted in more resource utilization. The test result did not influence the duration of isolation precautions. This implies that health care providers may not use the results of testing in making management decisions, or in guiding the use of isolation precautions. This study provides the foundation for further scientific evaluation and reform of our current respiratory infection control policy.

Abstract:
Pandemic outbreaks are unpredictable as to their virus strain, transmissibility, and impact on our quality of life. Hence, the decision support models for mitigation of pandemic outbreaks must be user-friendly and operational, and also incorporate valid estimates of disease transmissibility and severity. This dissertation research is aimed at 1) reviewing the existing pandemic simulation models to identify their implementation gaps with regard to usability and operability, and suggesting research remedies, 2) increasing operability of simulation models by calibrating them via an epidemiological model that estimates infection probabilities using viral shedding profiles of concurrent pandemic and seasonal influenza, and 3) developing a testing strategy for the state laboratories, with their limited capacities, to improve their ability to estimate evolving transmissibility parameters. Our review of literature (Aim 1) indicates the need to continue model enhancements in critical areas including updating of epidemiological data during a pandemic, smooth handling of large demographical databases, incorporation of a broader spectrum of social-behavioral aspects, and improvement of computational efficiency and accessibility. As regards the ease of calibration (Aim 2), we demonstrate that the simulation models, when driven by the infection probabilities obtained from our epidemiological model, accurately reproduce the disease transmissibility parameters. Assuming the availability of sufficient disease reporting infrastructure and strong compliance by both infected population and healthcare providers, our testing strategy (Aim 3) adequately supports characterization of real-time epidemiological parameters. Future research on this topic will be aimed at integrating the laboratory testing strategy with our modeling and simulation approach to develop dynamic mitigation strategies for pandemic outbreaks.

Abstract:
The high rates of depression and suicide among older adults have given rise to research which aims to identify factors that protect older people from mental illness. Recently, Bailey and McLaren (2005) developed and tested a model which investigated the relationships between engagement in various leisure activities performed alone or with others, sense of belonging, depression, and suicidal ideation. The present study examined an extended version of the mental health model, incorporating the additional variables of perceived freedom in leisure and physical health status. A sample of Australian males and females (N = 379) aged 65 years and over (M age = 77.23, SD = 7.48) completed the Perceived Freedom in Leisure Questionnaire, the Yale Physical Activity Survey,the Duke Health Profile, the Sense of Belonging Instrument, the Centre for Epidemiological Studies-Depressive Scale, and the Suicide Subscale of the General Health Questionnaire. Results indicated that the model was invariant for gender, and accounted for 56% of the variance in suicidal ideation. The model indicated that physical health had direct relationships with each variable in the model. Perceived freedom in leisure predicted engagement in physical activity, sense of belonging-antecedent, and depression, whereas sense of belonging psychological state predicted depression and suicidal ideation. Results suggest that interventions aimed at improving older adults’ perceptions of freedom and personal choice with regard to their leisure experiences, maintaining optimal health, and increasing opportunities to foster feelings of belonging and relatedness with others, should protect against the development of mental ill health.

Abstract:
Desinfektionsmittel sind ein elementarer Bestandteil der Tierseuchenbekämpfung und damit auch der Lebensmittelsicherheit. Die Prüfung chemischer Desinfektionsmittel ist Voraussetzung für deren zuverlässige Wirksamkeit und zielgerichteten Einsatz. In Deutschland geschieht dies nach den Richtlinien der Deutschen Veterinärmedizinischen Gesellschaft e.V. (DVG). Seit der ersten Fassung sind die Richtlinien einem ständigen Anpassungsprozess unterworfen. Im Zuge der europäischen Harmonisierung gilt es nun, sich gesamteuropäischen Richtlinien, verfasst durch das europäische Komitee für Normung (Comité Européen de Normalisation) (CEN) anzupassen. Das Thema dieser Arbeit entwickelte sich im Kontext der derzeitigen Diskussion über Verbesserungsvorschläge zu den bestehenden Richtlinien und deren Anpassung an die europäischen Normen. Es wurden je zwei Testviren für die Bereiche Tierhaltung und tierärztliche Praxis ausgewählt, um sie auf Eignung für die Viruzidieprüfung zu testen und gegebenenfalls zu etablieren. Des Weiteren wurde in einem zweiten Teil, in Anlehnung an die Forderungen der europäischen Normen die Prüfung zu vereinfachen, ein alternatives Zellkulturnachweissystem für das Newcastle-Disease-Virus (NDV) geprüft. Die Prüfung der viruziden Wirksamkeit erfolgte mit fünf verschiedenen Grundsubstanzen, gewählt um ein möglichst breites Spektrum an Desinfektionsmittelwirkstoffen abzudecken. Es wurden Glutaraldehyd, Ethanol, Natronlauge, Natriumhypochlorit und Peressigsäure verwendet. Die Versuche wurden mit einer niedrigen Eiweißbelastung und bei einer Temperatur von 20°C durchgeführt. Um eine praxisnahe Situation zu simulieren wurde auf, bereits in den DVG-Richtlinien, verankerten Stahl- und Holzkeimträgertests zurückgegriffen. Als mögliche Prüfviren für die Tierhaltung wurden das Equine Arteritis-Virus (EAV) und das Bovine Virus Diarrhoe Virus verwendet. Bei beiden Viren handelt es sich um weit verbreitete Tierseuchenerreger mit einer großen epidemiologischen Bedeutung. Die Untersuchung von fünf verschiedenen Desinfektionsmitteln erfolgte im Keimträgertest auf Holz. Sowohl EAV als auch BVD stellen ein weniger geeignetes Prüfvirus dar, da beide Viren enorme Titerverluste im Trocknungsvorgang der Holzkeimträger zeigten. Die Viren ließen sich zwar leicht vermehren, aber die erzielten Ausgangstiter reichten nicht aus um die Trocknungsverluste zu kompensieren und aussagekräftige Ergebnisse zu produzieren. Für den Bereich tierärztliche Praxis wurden das Feline Coronavirus (FCoV) und das Murine Parvovirus (MPV) genutzt. FCoV ist ein weltweit in Hauskatzenpopulationen vorkommendes Virus mit einer hohen Seroprävalenz und wurde daher ausgewählt. MPV wurde als Stellvertreter für die, in der Praxis häufig vorkommenden Parvovirusinfektionen gewählt. Es schien ein ideales Modellvirus aufgrund seiner weiten Verbreitung in der Forschung zu sein. Bei beiden Viren erfolgte die Prüfung auf Stahlkeimträgern. Unter Laborbedingungen konnte FCoV ohne Probleme zu hohen Titern vermehrt werden. Es gab keine nennenswerten Trocknungsverluste. FCoV erwies sich als geeignetes Prüfvirus. MPV hingegen ist bedingt durch die langen Versuchszeiten und schwierig auszuwertenden Zellkulturen, sowie wegen der niedrigen Ausgangstiter weniger geeignet als Modellvirus für die Desinfektionsmittelprüfung. Die Anzucht von NDV in Allantoisflüssigkeit von SPF Hühnereiern erschien sehr aufwendig und mit hohem Eiweißfehler belastet. In den Versuchen konnte ein deutlich höherer Eiweißgehalt als in den vergleichend geprüften, in Zellkultur angezogenen Viren nachgewiesen werden. Infolge der Probleme mit der Kultivierung der LMH-Zelllinie und den damit verbundenen langen Wartezeiten bis zur eigentlichen Versuchsdurchführung kann nur eine teilweise Empfehlung, von auf Zellkultur vermehrtem NDV (NDV (ZK)) gegeben werden. Nach Behebung dieser Probleme ist durchaus eine Ablösung, von in Allantoisflüssigkeit angezüchtetem NDV durch NDV (ZK) zu empfehlen. Die Verfälschung der Ergebnisse durch die höheren Eiweißgehalte bei Desinfektionsmitteln mit deutlichem Eiweißfehler könnten so vermieden werden.

Abstract:
The cost of adverse drug reactions to society in the form of deaths, chronic illness, foetal malformation, and many other effects is quite significant. For example, in the United States of America, adverse reactions to prescribed drugs is around the fourth leading cause of death. The reporting of adverse drug reactions is spontaneous and voluntary in Australia. Many methods that have been used for the analysis of adverse drug reaction data, mostly using a statistical approach as a basis for clinical analysis in drug safety surveillance decision support. This thesis examines new approaches that may be used in the analysis of drug safety data. These methods differ significantly from the statistical methods in that they utilize co variability methods of association to define drug-reaction relationships. Co variability algorithms were developed in collaboration with Musa Mammadov to discover drugs associated with adverse reactions and possible drug-drug interactions. This method uses the system organ class (SOC) classification in the Australian Adverse Drug Reaction Advisory Committee (ADRAC) data to stratify reactions. The text categorization algorithm BoosTexter was found to work with the same drug safety data and its performance and modus operandi was compared to our algorithms. These alternative methods were compared to a standard disproportionality analysis methods for signal detection in drug safety data including the Bayesean mulit-item gamma Poisson shrinker (MGPS), which was found to have a problem with similar reaction terms in a report and innocent by-stander drugs. A classification of drug terms was made using the anatomical-therapeutic-chemical classification (ATC) codes. This reduced the number of drug variables from 5081 drug terms to 14 main drug classes. The ATC classification is structured into a hierarchy of five levels. Exploitation of the ATC hierarchy allows the drug safety data to be stratified in such a way as to make them accessible to powerful existing tools. A data mining method that uses association rules, which groups them on the basis of content, was used as a basis for applying the ATC and SOC ontologies to ADRAC data. This allows different views of these associations (even very rare ones). A signal detection method was developed using these association rules, which also incorporates critical reaction terms.

Abstract:
AbstractA key component of current global HIV prevention efforts is widespread HIV testing. This strategy in part reflects the focus on the broader global targets to eliminate AIDS by achieving high rates of viral suppression. In this chapter we look at young people’s engagement with HIV prevention options in South-West Uganda. Taking a qualitative approach, using repeat in-depth interviews and participatory workshops with 50 young people aged 16–24 years old, we reflect on their accounts of how they navigate risks and opportunities within their daily lives. These risks include HIV-acquisition, but also the harms of economic precarity. Within a context in which using HIV prevention methods, such as condoms or abstinence, were for various reasons severely compromised by their contextual realities, some young people reported relying on irregular HIV testing as their singular method. The young people’s accounts demonstrate that an unintended consequence of the ‘push’ for HIV testing may be the justification of its replacement of other behavioural prevention strategies. This case study illustrates what impact such biomedical interventions may have if implemented as a priority and in isolation from the structural drivers of vulnerability: the social context of young people’s lives.

Abstract:
Research objectives: Identification of highly conserved B-cell epitopes common to either H5 or H9 subtypes of AI Reconstruction of conserved epitopes from (1) as recombinantimmunogens, and testing their suitability to be used as universal vaccine components by measuring their binding to Influenza vaccinated sera of birds Vaccination of chickens with reconstituted epitopes and evaluation of successful vaccination, clinical protection and viral replication Development of a platform to investigate the dynamics of immune response towards infection or an epitope based vaccine Estimate our ability to focus the immune response towards an epitope-based vaccine using the tool we have developed in (D) Summary: This study is a multi-disciplinary study of four-way collaboration; The SERPL, USDA, Kimron-Israel, and two groups at TAU with the purpose of evaluating the production and implementation of epitope based vaccines against avian influenza (AI). Systematic analysis of the influenza viral spike led to the production of a highly conserved epitope situated at the hinge of the HA antigen designated “cluster 300” (c300). This epitope consists of a total of 31 residues and was initially expressed as a fusion protein of the Protein 8 major protein of the bacteriophagefd. Two versions of the c300 were produced to correspond to the H5 and H9 antigens respectively as well as scrambled versions that were identical with regard to amino acid composition yet with varied linear sequence (these served as negative controls). The recombinantimmunogens were produced first as phage fusions and then subsequently as fusions with maltose binding protein (MBP) or glutathioneS-transferase (GST). The latter were used to immunize and boost chickens at SERPL and Kimron. Furthermore, vaccinated and control chickens were challenged with concordant influenza strains at Kimron and SEPRL. Polyclonal sera were obtained for further analyses at TAU and computational bioinformatics analyses in collaboration with Prof. Pupko. Moreover, the degree of protection afforded by the vaccination was determined. Unfortunately, no protection could be demonstrated. In parallel to the main theme of the study, the TAU team (Gershoni and Pupko) designed and developed a novel methodology for the systematic analysis of the antibody composition of polyclonal sera (Deep Panning) which is essential for the analyses of the humoral response towards vaccination and challenge. Deep Panning is currently being used to monitor the polyclonal sera derived from the vaccination studies conducted at the SEPRL and Kimron.

Foreit, James R. Postabortion family planning benefits clients and providers. Population Council, 2005. http://dx.doi.org/10.31899/rh16.1006.

Full text
Abstract:
A woman’s fertility can return quickly following an abortion or miscarriage, yet recent data show high levels of unmet need for family planning (FP) among women who have been treated for incomplete abortion. This leaves many women at risk of another unintended pregnancy and in some cases subsequent repeated abortions and abortion-related complications. It is thus vital for programs to provide a comprehensive package of postabortion care (PAC) services that includes medical treatment, FP counseling and services, and other reproductive health services such as evaluation and treatment for sexually transmitted infections, HIV counseling and/or testing, and community support and mobilization. Providing FP services within PAC benefits clients and programs. Facilities that can effectively treat women with incomplete abortions can also provide contraceptive services, including counseling and appropriate methods. As stated in this brief, any provider who can treat incomplete abortion can also provide selected FP methods. Clients, providers, and programs benefit when FP methods are provided to postabortion clients at the time of treatment.

Resistance to Tomato Yellow Leaf Curl Virus by Combining Expression of a Natural Tolerance Gene and a Dysfunctional Movement Protein in a Single Cultivar. United States Department of Agriculture, June 2000. http://dx.doi.org/10.32747/2000.7573079.bard.

Abstract:
Background The tomato yellow leaf curl disease (TYLCV) has been a major deterrent to tomato production in Israel for the last 20 years. This whitefly-transmitted viral disease has been found in the Caribbean Island in the early 1990s, probably as an import from the Middle East. In the late 1990s, the virus has spread to the US and is now conspicuous in Florida and Georgia. Objectives Because of the urgency facing the TYLCV epidemics, there was a compelling need to mobilize scientists to develop tomato variety resistant to TYLCV. The major goal was to identify the virus movement protein (MP) and to express a defective from of MP in a cultivar that contained the natural Ty-1 resistance gene. The research included 1. cloning of the TYLCV isolate from the Dominican Republic (DR) which is (or a close variant) also present in the continental USA; 2. ddefining the role of the MP; 3. mutating the putative MP gene; 4. introducing the modified gene into an advance Ty-1 line; 5. testing the transgenic plants in the field. The pressing threat to tomato production in the US resulted in an extension of the objectives: more emphasis was placed on characterization of TYLCV i the DR, on determination of the epidemiology of the virus in the DR, and on using new TYLCV resistance sources for tomato breeding. Achievements and signification 1. The characterization of TYLCV-DR allowed for more effective TYLCV management strategies that are now implemented in the DR. 2. The identification of the TYLCV MPs and, more importantly, insight into their function has provided a model for how these proteins function in TYLCV movement and support the targeting of one or more of these proteins in a dominant lethal strategy to engineer plants for TYLCV resistance. 3. The transgenic plants that are being generated with wild-type and mutated TYLCV MPs will serve to test the hypothesis that interference with one or more of the TYLCV movement proteins will be a strategy for generating TYLCV-resistant plants. 4. The fine mapping of the resistance Ty-1 gene allowed eliminating deleterious chromosome segments from the wild tomato genitor L. chilense. It may in a near future allow the cloning of the first geminivirus resistance gene. 5. Another resistance source from the wild tomato species L. hirsitum was introgressed into the domesticated tomato, resulting in the production of resistant breeding lines. Implications 1. The monitoring of TYLCV in whiteflies has been applied in the DR. These tools are presently being used to assist in the evaluation of the host-free period and to help select the appropriate locations for growing tomatoes in the DR. 2. An overall strategy to obtain resistance against TYLCV has been used. The expression of wild-type or mutated TYLCV MPs in transgenic tomato is another addition to the arsenal used to fight TYLCV, together with marker assisted breeding and mobilization of additional resistant genes from the wild.

Full text
Abstract:
Preventing unintended pregnancy among HIV-positive women is an effective approach to reducing pediatric HIV infection and vital to meeting HIV-positive women’s sexual and reproductive health needs. Although contraceptive services for HIV-positive women is one of the cornerstones of a comprehensive program for prevention of mother-to-child transmission of HIV (PMTCT), a review of PMTCT programs found that implementers have not prioritized family planning (FP). While there is increasing awareness about the importance of FP and HIV integration, data about FP from PMTCT clients are lacking. The Horizons Program is conducting an operations research study testing several community-based strategies to reduce mother-to-child transmission of HIV in a densely settled urban slum in Nairobi, Kenya. Strategies being piloted include moving PMTCT services closer to the population via a mobile clinic and increasing psychosocial support for HIV-positive women. This research update presents key findings about FP at PMTCT sites, including the interaction between providers and clients as well as HIV-positive women’s fertility desires and demand for contraceptives, from the baseline cross-sectional survey and qualitative interviews with postpartum women.

Full text
Abstract:
COVID-19, caused by the SARS-CoV-2 virus, was first reported in China in December 2019. The virus has spread rapidly around the world and is currently responsible for 500 million reported cases and over 6.4 million deaths. A risk assessment published by the Foods Standards Agency (FSA) in 2020 (Opens in a new window) concluded that it was very unlikely that you could catch coronavirus via food. This assessment included the worst-case assumption that, if food became contaminated during production, no significant inactivation of virus would occur before consumption. However, the rate of inactivation of virus on products sold at various temperatures was identified as a key uncertainty, because if inactivation does occur more rapidly in some situations, then a lower risk may be more appropriate. This project was commissioned to measure the rate of inactivation of virus on the surface of various types of food and food packaging, reducing that uncertainty. The results will be used to consider whether the assumption currently made in the risk assessment remains appropriate for food kept at a range of temperatures, or whether a lower risk is more appropriate for some. We conducted a laboratory-based study, artificially contaminating infectious SARS-CoV-2 virus onto the surfaces of foods and food packaging. We measured how the amount of infectious virus present on those surfaces declined over time, at a range of temperatures and relative humidity levels, reflecting typical storage conditions. We tested broccoli, peppers, apple, raspberry, cheddar cheese, sliced ham, olives, brine from the olives, white and brown bread crusts, croissants and pain au chocolat. The foods tested were selected as they are commonly sold loose on supermarket shelves or uncovered at deli counters or market stalls, they may be difficult to wash, and they are often consumed without any further processing i.e. cooking. The food packaging materials tested were polyethylene terephthalate (PET1) trays and bottles; aluminium cans and composite drinks cartons. These were selected as they are the most commonly used food packaging materials or consumption of the product may involve direct mouth contact with the packaging. Results showed that virus survival varied depending on the foods and food packaging examined. In several cases, infectious virus was detected for several hours and in some cases for several days, under some conditions tested. For a highly infectious agent such as SARS-CoV-2, which is thought to be transmissible by touching contaminated surfaces and then the face, this confirmation is significant. For most foods tested there was a significant drop in levels of virus contamination over the first 24 hours. However, for cheddar cheese and sliced ham, stored in refrigerated conditions and a range of relative humidity, the virus levels remained high up to a week later, when the testing period was stopped. Both cheddar cheese and sliced ham have high moisture, protein and saturated fat content, possibly offering protection to the virus. When apples and olives were tested, the virus was inactivated to the limit of detection very quickly, within an hour, when the first time point was measured. We suggest that chemicals, such as flavonoids, present in the skin of apples and olives inactivate the virus. The rate of viral decrease was rapid, within a few hours, for croissants and pain au chocolat. These pastries are both coated with a liquid egg wash, which may have an inhibitory effect on the virus. Food packaging materials tested had variable virus survival. For all food packaging, there was a significant drop in levels of virus contamination over the first 24 hours, in all relative humidity conditions and at both 6°C and 21°C; these included PET1 bottles and trays, aluminium cans and composite drinks cartons.

Abstract:
The article investigates the immortality of books, collections, including those, translated into foreign languages, composed of the publications of publications of worldview journalism. It deals with top analytics on simulated training of journalists, the study of events and phenomena at the macro level, which enables the qualitative forecast of world development trends in the appropriate contexts for a long time. Key words: top, analytics, book, worldview journalism, culture, arguments, forecast.The article is characterized intellectual-spiritual, moral-aesthetic and information-educational values of of scientific and journalistic works of Professor Mykola Hryhorchuk “Where are you going, Ukraine?” and “Freedom at the Barricades”. Mykola Ivanovych’s creative informational and educational communication are reviews, reviews, reviews and current works of writers, poets, publicists. Such as Maria Matios, Vira Vovk, Roman Ivanychuk, Dmytro Pavlychko, Yuriy Shcherban, Bohdan Korsak, Hryhoriy Huseynov, Vasyl Ruban, Yaroslav Melnyk, Sofia Andrukhovych. His journalistic reflections are about memorable events of the recent past for Ukrainians and historical figures are connected with them. It is emphasized that in his books Mykola Hryhorchuk convincingly illuminates the way to develop a stable Ukrainian immunity, national identity, development and strengthening of the conciliar independent state in the fight against the eternal Moscow enemy. Among the defining ideological and political realization of the National Idea of Ukrainian statehood, which are mentioned in the scientific and journalistic works of M. Hryhorchuk, the fundamental ones – linguistic and religious – are singled out. Israel and Poland are a clear example for Ukrainians. In these states, language and religion were absolutized and it is thanks to this understanding of the essence of state-building and national identity that it is contrary to many difficulties achieve the desired life-affirming goal. The author emphasizes that any information in the broadest and narrow sense can be perceived without testing for compliance with the moral and spiritual mission of man, the fundamental values of the Ukrainian ethnic group, putting moral and spiritual values in the basis of state building. The outstanding Ukrainian philosopher Hryhoriy Skovoroda emphasized: “Faith is the light that sees in the darkness…” Books by physicist Mykola Hryhorchuk “Where are you going, Ukraine?” and “Freedom at the Barricades” are illuminated by faith in the Victory over the bloody centuries-old Moscow darkness.
