Abstract:
Purpose: The Timed Up and Go (TUG) test is a reliable, cost-effective, safe, and time-efficient way to evaluate overall functional mobility. However, the TUG does not have normative reference values (NRV) for individuals younger than 60 years. The purpose of this study was to establish NRV for the TUG for individuals aged between 20 and 59 years and to examine the relationship between the TUG and demographic, physical, and mental health risk factors. Methods: Two hundred participants, 50 per decade (ages 20-29, 30-39, 40-49, 50-59 years) were selected at their primary care visit, and timed as they performed the TUG by standing up out of a chair, walking 3 m, turning around, walking back to the chair, and sitting down. Information regarding the risk factors socioeconomic status, body mass index, an index of multimorbidities, perceptions of overall physical and mental health was obtained and used as predictors of TUG time independent of age. Results: TUG times were significantly different among the decades ( F = 6.579, P = .001) with slower times occurring with the 50-year-old decade compared with the 20s ( P = .001), 30s ( P = .001), and 40s ( P = .020). Slower TUG times were associated with lower SES, higher body mass index, more medical comorbidities, and worse perceived physical and mental health. Regression results indicated that perceived physical and mental health accounted for unique variance in the prediction of TUG time beyond age, gender, and socioeconomic status. Conclusions: This study provided TUG NRV for adults in their 20s, 30s, 40s, and 50s. The TUG may have utility for primary care providers as they assess and monitor physical activity in younger adults, especially those with physical and mental health risk factors.

The Timed-Up and Go test (TUG) is a well-known medical test that is used as an indicator of mental and physical health. I developed the TUG-Segmenter, an automatic segmentation tool that can divide recorded TUG test data into the six main phases of the test: Sitting, Standing-Up, Walking-Forward, Turning, Walking-Back, and Sitting-Down. I created an annotation tool as well that greatly speeds up the creation of ground truth from TUG test data. Using both these tools I was able to evaluate the accuracy of the TUG-Segmenter in terms of the duration of the segmented phases ( 83.4 % accurate ) and the start times of the segmented phases ( 83.6 % accurate). Lastly, I found a 0.3 cm difference for jitteriness and an 8.5 mm/s difference for speed between healthy elderly subjects and healthy young subjects when comparing the features extracted from the individual TUG test phases.

Abstract:
Dans le milieu de la réadaptation, il est important que les physiothérapeutes puissent mesurer les changements survenus suite à leurs interventions afin d'ajuster celles-ci. En pédiatrie, il existe peu d'instruments de mesure dont la fidélité, validité et sensibilité au changement ont été étudiées chez les enfants ayant un déficit moteur cérébral (DMC). Le Gross Motor Function Measure (GMFM) est l'instrument le plus utilisé auprès de cette clientèle pour mesurer les changements moteurs parce que ses qualités métrologiques ont été bien démontrées. Par contre, ce test est long à administrer et peut difficilement être utilisé en dehors d'un gymnase de physiothérapie. Cette recherche vise à valider un test plus rapide pour mesurer les progrès moteurs des enfants DMC, le Timed Up and Go (TUG), test fréquemment utilisé en gériatrie. Cette étude, qui s'échelonnait sur 10 mois, a été réalisée auprès de vingt enfants ambulants de 3 à 16 ans ayant différents diagnostics de déficit moteur cérébral.--Résumé abrégé par UMI.

An experimental study was performed to understand lower limb movement patterns between older and young adults, and to explore a new metric of coordination. Lower limb and torso movement in an older and younger population was captured using both IMU sensors and an optical tracking system. Only data from the optical method was processed and analyzed for this thesis. The participants executed several trials of a Timed-Up-and-Go test (TUGT), a 10 meter Walk Test (10MWT), and a Standing Balance Test (SBT). This paper specifically analyzed data from seven of the participants when executing the TUG test. The Relative Coordination Metric (RCM) from Hip to Knee and from Knee to Ankle was briefly explored for one subject from each age group. Several qualitative differences in motion were seen between the younger subject and the older subject for the Hip-Knee RCM, while similarities were identified for the Knee-Ankle RCM. The TUG time for the younger age group (M = 11.48s, SD = 1.26s) and the older age group (M = 12.06s, SD = 0.69s) was also compared and it was found that they were significantly different (t =1.998, p = 0.017).

Introduction : The Timed “Up &Go” (TUG) test has been used in the assessment of the functional mobility and only few studies have tested it in a healthy pediatric population, as well as in patients with Down Syndrome (DS).Objectives : To determine normative values for the TUG test in healthy children and adolescents and to validate its use in a sample of patients with DS. Methods : A cross-sectional study divided into two phases. Children and adolescents, from 3 to 18 years old, healthy (phase1), or with DS (phase 2), were selected by convenience to be assessed with the TUG test. The assessments were performed in the following order: anthropometric measurements, actual lower limb length, TUG and Gross Motor Functional Measurements (GMFM) – this one was only performed in phase 2. The association between the TUG test values and the possible predictive variables was analyzed using a model of multiple linear regression. Results : In phase 1 (459 participants), the TUG test values were different across the participants age and, because of that, they were stratified in age groups that serve as normative values for both genders. The regression model has demonstrated that the age and the weight (R2=0,25) were the best variables for the TUG test prediction. The intraclass correlation coefficient (ICC) demonstrated excellent within-session and between-session reliability. In phase 2 (40 individuals with DS), the test also showed excellent reproducibility. The performance time was significantly higher in individuals with DS compared with gender, age and weight matched healthy controls. Also, the dimension E of the GMFM was the variable that best correlated with the TUG test. Conclusion : This study provides normative values for the TUG test and shows that its behavior can be explained according to the age and weight in healthy children and adolescents. The TUG test is a reliable and valid assessment of functional mobility in patients with SD and correlates with the gross motor function.
Introdução : O teste Timed “Up & Go” (TUG) vem sendo utilizado na avaliação da mobilidade funcional e poucos estudos o avaliaram na população pediátrica saudável e em pacientes com Síndrome de Down (SD).Objetivos : Determinar valores normativos para o teste TUG em crianças e adolescentes saudáveis e validar a sua utilização em uma amostra de pacientes com SD. Material e métodos : Estudo observacional transversal dividido em duas fases. Crianças e adolescentes, de 3 a 18 anos, saudáveis (fase 1) ou com SD (fase 2),foram selecionadas por conveniência para a avaliação com o teste TUG. As avaliações foram realizadas na seguinte ordem: medidas antropométricas, comprimento real dos membros inferiores, TUG e Gross Motor Function Measure (GMFM), este último realizado apenas na fase 2. A associação entre os valores do teste TUG com as potenciais variáveis preditoras foi analisada utilizando um modelo de regressão linear múltipla. Resultados : Na fase 1 (459 participantes), os valores do teste TUG diferiram no decorrer das idades e por isso foram estratificadas em faixas etárias que servem como valores normativos para ambos os sexos. O modelo de regressão demonstrou que a idade e o peso (R2=0,25) foram as melhores variáveis para a predição do TUG. O coeficiente de correlação intraclasse (ICC) demonstrou excelente confiabilidade intra-sessão e inter-sessão. Na fase 2 (40 indivíduos com SD), o teste também apresentou excelente reprodutibilidade. O tempo de realização foi significativamente maior nos indivíduos com SD quando comparados com os saudáveis pareados por sexo, idade e peso. Ainda, a dimensão E do GMFM foi a variável que melhor se correlacionou com o teste TUG. Conclusão : Este estudo apresenta valores normativos para o teste TUG e demonstra que o seu comportamento pode ser explicado em função da idade e do peso em crianças e adolescentes saudáveis. O TUG é confiável e válido para avaliação da mobilidade funcional em pacientes com SD e se correlaciona com a função motora grossa.

Abstract:
Le risque de chute chez la personne âgée est un enjeu majeur de santé publique. Sa détection précoce permettrait d’intervenir en amont de la première chute ou en prévenir la récidive en proposant de l’activité physique préventive adaptée. Or, l’évaluation d’un risque de chute avec les tests et échelles fréquemment utilisés ne donne pas pleinement satisfaction. Les récentes innovations technologiques dans le domaine de la réalité virtuelle immersive laissent penser que son utilisation dans l’évaluation des risques de chute pourrait combler certains manques de contextualisation et d’uniformité des tests actuels. Toutefois, avant d’utiliser ces technologies dans l’évaluation du risque de chute, il est important de connaître leur impact sur le comportement moteur. Pour cela, nous avons choisi de tester une tâche locomotrice, le Timed Up and Go (TUG - test clinique très utilisé par les cliniciens et véritable « gold standard » dans l’évaluation des risques de chute chez la personne âgée), en environnement réel et en environnement virtuel auprès de personnes âgées ainsi que de jeunes adultes. Des différences sont observées avec des augmentations du temps et du nombre de pas en réalité virtuelle. Ainsi, la réalité virtuelle immersive pourrait être une piste de choix dans l’évaluation du risque de chute par l’augmentation de la sensibilité et de la spécificité des tests puisqu’elle permet de contextualiser l’environnement de test. Toutefois, cette solution pourrait n’être que temporaire étant donné les promesses de la réalité mixte qui permettrait, elle, à la fois de contextualiser le test dans l’environnement réel avec un contrôle numérique des contraintes qui peuvent être ajoutées à cet environnement
Risk of fall in the elderly is a major public health issue. Its early detection would make it possible to intervene before the first fall or prevent its recurrence by offering suitable preventive physical activity. However, the assessment of a fall risk with frequently used tests and scales is not fully satisfactory. Recent technological innovations in the field of immersive virtual reality suggest that its use in the assessment of fall risk could fill some gaps in contextualization and uniformity of current tests. However, before using these technologies in the fall risk assessment, it is important to know their impact on motor behavior. To do this, we chose to test a locomotor task, the Timed Up and Go (TUG - a clinical test widely used by clinicians and a real “gold standard” in the evaluation of the risk of falls in the elderly), in a real environment. and in a virtual environment with the elderly as well as young adults. Differences are observed with increases in time and number of steps in virtual reality. Thus, immersive virtual reality could be an avenue of choice in the assessment of the risk of falls by increasing the sensitivity and specificity of the tests since it allows to contextualize the test environment. However, this solution could only be temporary given the promises of mixed reality which would allow both to contextualize the test in the real environment with digital control of the constraints that can be added to this environment

Abstract:
AbstractUniversities are not only the anchors, shapers and innovators of nations but they galvanise the building and rebuilding of nations. They are a source of knowledge, an arena to develop understanding and provide the vehicles for interpreting and addressing the key challenges of our time. Nations need universities to develop home-grown solutions for the problems and opportunities with which they are presented, and so they can participate with value and confidence in international scientific eco-systems. Yet, national universities do not and should not act alone. Agenda 2030 and the Sustainable Development Goals constitute the principal international convention of our time and offer a positive step in recognising the importance of tertiary education to individual and social advancement. However, they do not go far enough, particularly from the vantage point of nations with ambitions to grow prosperous economies and engaged societies. This chapter explores the national and international role of universities and the benefits or otherwise of the internationalisation of higher education and global conventions such as Agenda 2030.

Abstract:
AbstractIn this volume, both qualitative and quantitative scholars describe their findings on the networks of migrants and their descendants and explore the content of their social ties for educational and labor market success in seven European countries. Some contributions cover decades of work in this field, making this one of most comprehensive books on this topic, both theoretically and empirically. Almost without exception, the authors, although describing various ethnic groups, different geographical and professional contexts and different time periods, are critical of a number of the main arguments about the networks of migrants developed in the field of migration studies. Central in their critique is the question about the importance of co-ethnic or inter-ethnic ties and networks, and their importance to enter the labor market and move up. In the field of migration studies, concepts like integration and assimilation have greatly influenced the thinking of its scholars. The idea that newcomers only become fully integrated in a society when they gain a similar economic position and are in contact with people without migration background, or, in other words, become part of the mainstream, has been a strong and dominant view in our field (Alba & Nee, 2003; Alba, 2009; Portes & Rumbaut, 2001; Portes & Zhou, 1993). People who largely interact with co-ethnics and or work in labor market sectors that are dominated by co-ethnics (ethnic niches) are usually seen as not (yet) fully integrated into their new society. And when this also translates to the native-born children (so-called ‘second generation decline’), this is seen as problematic (Ganz, 1992). In this broader framework on integration and assimilation, Granovetter’s (1973) idea of strong and weak ties has entered the field of migration studies. Lang and Schneider, in this volume, rightly state that it is questionable whether the idea of strong ties – for co-ethnics – and weak ties – for ties with people without migration background – was originally intended by Granovetter to be used in this way. But what is clear, however, is that this idea fitted perfectly with broader theories on integration and assimilation. The importance for newly arrived migrants of strong co-ethnic ties in ethnic networks is generally considered one of the starting pieces of the puzzle laying out the process of assimilation in its first phase. The idea of weak ties, also in its symbolic emphasis on ‘weak’, perfectly suited the still scarce and superficial contacts with people of native descent in the early stages of the assimilation process. Since the concept of weak and strong ties fitted so well with the dominant theories about integration and assimilation (classical, neo and new assimilation), much of what was happening with migrants, and even their descendants, in the labor market was seen through, what many would call, an ethnic lens (Crul, 2016; Dahinden, 2016; Wimmer, 2013). Migrants gained a first foothold in the labor market through strong co-ethnic ties and were slowly moving up through their weak ties, making use of information and resources of people of native descent with whom they had only superficial contact. The idea of strong ties also resonated with the notion that their relations with co-ethnics were more meaningful and profound. There was also a dark side to strong ties. Under some conditions, because of the limited information and resources in the co-ethnic network, for some the strong ties could lead to an ethnic mobility trap.

Abstract:
AbstractDespite enduring political rhetoric that promotes Australia as ‘the lucky country’ and ‘the land of the fair go’, recent decades have seen a noticeable increase in levels of income inequality. This growing economic divide has driven housing prices up and left lower-income families unable to access the housing market in inner-city locations. In contrast to other countries, Australia’s socioeconomic segregation does not overlap with ethnic segregation. Australia’s highly regulated immigration program has resulted in a relatively well-educated and employable foreign-born population who largely reside in middle-income neighbourhoods. These particularities make Australia an interesting context to explore patterns of socioeconomic segregation over time. In this chapter, we will utilise both traditional measures of segregation (such as the dissimilarity index) as well more spatialised measures (such as location quotients and Local Morans I) to assess socioeconomic segregation at the local level. Drawing on four waves of census data (2001, 2006, 2011 and 2016), we explore how socioeconomic segregation has changed over time across nearly 500 neighbourhoods in Melbourne. We further examine the degree to which socioeconomic segregation aligns with ethnic segregation patterns and levels in this city. We find patterns of socioeconomic segregation remain relatively unchanging over time in Melbourne. Additionally, our findings highlight important differences in patterns and levels of socioeconomic and ethnic segregation in the Australian context.

Abstract:
AbstractWe formalize the simulation paradigm of cryptography in terms of category theory and show that protocols secure against abstract attacks form a symmetric monoidal category, thus giving an abstract model of composable security definitions in cryptography. Our model is able to incorporate computational security, set-up assumptions and various attack models such as colluding or independently acting subsets of adversaries in a modular, flexible fashion. We conclude by using string diagrams to rederive the security of the one-time pad and no-go results concerning the limits of bipartite and tripartite cryptography, ruling out e.g., composable commitments and broadcasting.

Abstract:
As a student undertaking a Longitudinal Integrated Clerkship (LIC)1 based in a GP practice in a rural community in the North of Scotland, I have been lucky to be given responsibility and my own clinic lists. Every day I conduct consultations that change my practice: the challenge of clinically applying the theory I have studied, controlling a consultation and efficiently exploring a patient's problems, empathising with and empowering them to play a part in their own care2 – and most difficult I feel – dealing with the vast amount of uncertainty that medicine, and particularly primary care, presents to both clinician and patient. I initially consulted with a lady in her 60s who attended with her husband, complaining of severe lower back pain who was very difficult to assess due to her pain level. Her husband was understandably concerned about the degree of pain she was in. After assessment and discussion with one of the GPs, we agreed some pain relief and a physio assessment in the next few days would be a practical plan. The patient had one red flag, some leg weakness and numbness, which was her ‘normal’ on account of her multiple sclerosis. At the physio assessment a few days later, the physio felt things were worse and some urgent bloods were ordered, unfortunately finding raised cancer and inflammatory markers. A CT scan of the lung found widespread cancer, a later CT of the head after some developing some acute confusion found brain metastases, and a week and a half after presenting to me, the patient sadly died in hospital. While that was all impactful enough on me, it was the follow-up appointment with the husband who attended on the last triage slot of the evening two weeks later that I found completely altered my understanding of grief and the mourning of a loved one. The husband had asked to speak to a Andrew MacFarlane Year 3 ScotGEM Medical Student 2 doctor just to talk about what had happened to his wife. The GP decided that it would be better if he came into the practice - strictly he probably should have been consulted with over the phone due to coronavirus restrictions - but he was asked what he would prefer and he opted to come in. I sat in on the consultation, I had been helping with any examinations the triage doctor needed and I recognised that this was the husband of the lady I had seen a few weeks earlier. He came in and sat down, head lowered, hands fiddling with the zip on his jacket, trying to find what to say. The GP sat, turned so that they were opposite each other with no desk between them - I was seated off to the side, an onlooker, but acknowledged by the patient with a kind nod when he entered the room. The GP asked gently, “How are you doing?” and roughly 30 seconds passed (a long time in a conversation) before the patient spoke. “I just really miss her…” he whispered with great effort, “I don’t understand how this all happened.” Over the next 45 minutes, he spoke about his wife, how much pain she had been in, the rapid deterioration he witnessed, the cancer being found, and cruelly how she had passed away after he had gone home to get some rest after being by her bedside all day in the hospital. He talked about how they had met, how much he missed her, how empty the house felt without her, and asking himself and us how he was meant to move forward with his life. He had a lot of questions for us, and for himself. Had we missed anything – had he missed anything? The GP really just listened for almost the whole consultation, speaking to him gently, reassuring him that this wasn’t his or anyone’s fault. She stated that this was an awful time for him and that what he was feeling was entirely normal and something we will all universally go through. She emphasised that while it wasn’t helpful at the moment, that things would get better over time.3 He was really glad I was there – having shared a consultation with his wife and I – he thanked me emphatically even though I felt like I hadn’t really helped at all. After some tears, frequent moments of silence and a lot of questions, he left having gotten a lot off his chest. “You just have to listen to people, be there for them as they go through things, and answer their questions as best you can” urged my GP as we discussed the case when the patient left. Almost all family caregivers contact their GP with regards to grief and this consultation really made me realise how important an aspect of my practice it will be in the future.4 It has also made me reflect on the emphasis on undergraduate teaching around ‘breaking bad news’ to patients, but nothing taught about when patients are in the process of grieving further down the line.5 The skill Andrew MacFarlane Year 3 ScotGEM Medical Student 3 required to manage a grieving patient is not one limited to general practice. Patients may grieve the loss of function from acute trauma through to chronic illness in all specialties of medicine - in addition to ‘traditional’ grief from loss of family or friends.6 There wasn’t anything ‘medical’ in the consultation, but I came away from it with a real sense of purpose as to why this career is such a privilege. We look after patients so they can spend as much quality time as they are given with their loved ones, and their loved ones are the ones we care for after they are gone. We as doctors are the constant, and we have to meet patients with compassion at their most difficult times – because it is as much a part of the job as the knowledge and the science – and it is the part of us that patients will remember long after they leave our clinic room.

And after all that effort, you have nothing to wear to soak up urine if it happens again. What if you didn’t know that leaking urine was common, and you spent the rest of the day worried about your health and too embarrassed to go to work in case people could tell? What if you were worried that your partner would hit you again for making a mess so you had very little to drink all day for fear of it happening again? What can you do to support people living with incontinence? To start, we need to talk about leaks.

Abstract:
Whereas at the end of the 20th century there were still high expectations associated with the use of new media in terms of a democratisation of social discourse and new potential for citizens to participate in political decision-making, disillusionment is now spreading. Even today, the internet is often seen only as a technical tool for the transmission of information and communication, which serves as a structural supplement to "real" discourse and decision-making processes. In fact, however, the use of new media can open up additional, previously non-existent possibilities for well-founded and substantial citizen participation, especially at regional and supra-regional level. According to the results of this study, the informal, mediative procedures for conflict resolution in the context of high-risk planning decisions, which are now also increasingly used at the regional level, have two main problem areas. Firstly, in the conception and design chosen so far, they do not offer citizens direct access to the procedure. Citizens are given almost no opportunities to exert substantial influence on the content and procedure of the process, or on the solutions found in the process. So far, this has not been remedied by the use of new media. On the other hand, it is becoming apparent that the results negotiated in the procedure are not, or only inadequately, reflected in the subsequent sovereign decision. This means that not only valuable resources for identifying the problem situation and for integrative problem-solving remain unused, but it is also not possible to realise the effects anticipated with the participation procedures within the framework of context or reflexive self-management. With the aim of advancing the development of institutionally oriented approaches at the practice level, this study discusses potential solutions at the procedural level. This takes into account legal implications as well as the action logics, motives and intentions of the actors involved and aims to improve e-government structures. It becomes evident that opening up informal participation procedures for citizen participation at the regional level can only be realised through the (targeted) use of new media. However, this requires a fundamentally new approach not only in the participation procedures carried out but also, for example, in the conception of information or communication offerings. Opportunities for improving the use of the results obtained from the informal procedures in the (sovereign) decision-making process as well as the development of potentials in the sense of stronger self-control of social subsystems are identified in a stronger interlinking of informal and sovereign procedures. The prerequisite for this is not only the establishment of suitable structures, but above all the willingness of decision-makers to allow citizens to participate in decision-making, as well as the granting of participation opportunities and rights that go beyond those previously granted in sovereign procedures.

Full text
Abstract:
Leguminous forage crops are high in proteins but deficient in S- amino acids. It has been shown that both wool quality and milk production can be limited by the post-ruminal supply of sulfur-containing amino acids. Efforts to use conventional plant breeding and cell selection techniques to increase the S-amino acid content of alfalfa have met with little success. With the objective to increase the S-amino acid content of forage legumes, the goal of this project was to co- express the methionine rich zein genes from corn along with a gene for a key enzyme in methionine biosynthesis, aspartate kinase(AK). The zeins are seed storage proteins from corn and are groupec into four distinct classes based on their amino acid sequence homologies. The b-zein (15kd) and the 6zein (10kD and 18kD) have proportionately high levels of methionine (10%, 22% and 28%, respectively). Initial studies from our lab had shown that while the 15kD zein accumulated to high levels in vegetative tissues of transgenic tobacco the l0kD zein did not. However, co-expression of the 10kD zein with the 15kD zein genes in tobacco showed stabilization of the 10kD zein and the co-localization of the 10kD and 15kD zein proteins in unique ER derived protein bodies. AK is the key enzyme for producing carbon skeletons for all amino acids of the aspartate family including methionine. It is, however, regulated by end-product feedback inhibition. The specific objectives of this proposal were: i. to co-express the 15kD zein with the 10/18kD zein genes in alfalfa in order to enhance the level of accumulation of the 10/18kD zein; ii. to increase methionine pools by expressing a feedback insensitive AK gene in transformants co-expressing the 15kD and 10/18kD zein genes. The Israeli partners were successful in expressing the AK gene in alfalfa which resulted in an increase in free and bound threonine but not in methionine (Galili et al., 2000). Since our target was to increase methionine pools, we changed our second objective to replace the AK gene with the gene for cystathionine gamma synthase (CGS) in the co-expression studies. The first methionine specific reaction is catalyzed by CGS. An additional objective was to develop a transformation system for Berseem clover, and to introduce the appropriate gene constructs into it with the goal of improving their methionine content. Genes for the 15kD zein along with the genes for either the 10kD or 18kD zein have been introduced into the same alfalfa plant both by sexual crosses and by re-transformation. Analysis of these zein co-expressors have shown that both the IOkD and 18kD zein levels go up 5 to 10 fold when co-expressed with the 15kD zein (Bagga et al., MS in preparation). Incubation of the leaves of transgenic alfalfa co-expressing the 15kD and 10kD zein genes, in the rumen of cows have shown that the zein proteins are stable in the rumen. To increase the level of zein accumulation in transgenic alfalfa different promoters have been used to drive the zein genes in alfalfa and we have concluded that the CaMV 35S promoter is superior to the other strong leaf -specific promoters. By feeding callus tissue of alfalfa plants co-expressing the 15kD and 10kD zein genes with methionine and its precursors, we have shown that the zein levels could be significantly enhanced by increasing the methionine pools. We have now introduced the CGS gene (from Arabidopsis; kindly provided to us by Dr. Leustek), into the 15kD zein transformants and experiments are in progress to check if the expression of the CGS gene indeed increases the level of zein accumulation in alfalfa. We were not successful in developing a transformation protocol for Berseem clover.

Evaluation of United Nations-supported pilot projects for the prevention of mother-to-child transmission of HIV: Overview of findings. Population Council, 2003. http://dx.doi.org/10.31899/hiv2003.1008.

Full text
Abstract:
Worldwide about 800,000 children a year get HIV infections from their mothers—either during pregnancy, childbirth, or breastfeeding. Countries have the potential to prevent a large share of these infections through low-cost, effective interventions. UN agencies have taken the lead in helping developing countries mount programs for prevention of mother-to-child transmission (PMTCT). This working paper presents key findings from an evaluation of UN-supported pilot PMTCT projects in 11 countries: Botswana, Burundi, Cote d’Ivoire, Honduras, India, Kenya, Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe. Key findings include feasibility and coverage, factors contributing to program coverage, program challenges, scaling up, the special case of low-prevalence countries, and recommendations. The pilot experience has shown that introducing PMTCT programs into antenatal care in a wide variety of settings is feasible and acceptable to a significant proportion of antenatal care clients who have a demand for HIV information, counseling, and testing. As they go to scale, PMTCT programs can learn from the pilot phase, during which hundreds of thousands of clients were successfully reached.
