Evidence for Action on HIV Treatment and Care Systems in low and middle-income countries: background and introduction.
Despite the unprecedented scale-up of treatment for HIV in low and middle-income countries over the past decade, 49% of adults and 77% of children in need of HIV treatment still do not have access to it. ART programmes that were initially set up as an emergency response now need to be adapted to ensure that they include all the essential components and are well integrated with other health services; meet the needs of special groups, including children, adolescents, pregnant women and older people; address the mental health needs of HIV-positive people; and monitor as well as report their impact in valid and comparable ways.This supplement is an output from the Evidence for Action on HIV Treatment and Care Systems research programme consortium. Evidence for Action was a 5-year, multidisciplinary research programme, which ran from 2006 to 2011, with partners in India, Malawi, Uganda, Zambia and the United Kingdom.The primary aim of this supplement is to stimulate reflection and provide guidance on what should be in the package of HIV treatment and care systems, as national programmes look to maintain the major advances of the past decade and scale-up treatment to the other 50% of people in need of it
What are the essential components of HIV treatment and care services in low and middle-income countries: an overview by settings and levels of the health system?
OBJECTIVES: To review and summarize the essential components of HIV treatment and care services in low and middle-income countries (LMICs). METHODS: Literature review and reflection on programmatic experience. FINDINGS: There is increasing recognition that the essential 'package' of HIV care must include early identification of HIV-positive people in need of care, appropriate initial and continued counselling, assessment of HIV disease stage, treatment with HAART for those who need it, monitoring while on treatment for efficacy, adherence and side-effects, detection and management of other complications of HIV infection, provision of sexual and reproductive health services as well as careful record-keeping. The impressive scale-up of HIV treatment and care services has required decentralization of service provision linked to task-shifting. But the future holds even greater challenges, as the number of people in need of HIV care continues to rise at a time when many traditional donors and governments in the most-affected regions have reduced budgets. CONCLUSION: In the long-term, the increased demand for HIV-care services can only be satisfied through increased decentralisation to peripheral health units, with the role of each type of unit being appropriate to the human and material resources available to it.HIV-care services can also naturally integrate with the care of chronic noncommunicable diseases and with closely related services like mother and child health, and thus should promote a shift from vertical to integrated programming. Staff training and support around a set of evidence-based policies and guidelines and a reliable supply of essential medicines and supplies are further essential components for a successful programme
Circuit Synthesis of Electrochemical Supercapacitor Models
This paper is concerned with the synthesis of RC electrical circuits from
physics-based supercapacitor models describing conservation and diffusion
relationships. The proposed synthesis procedure uses model discretisation,
linearisation, balanced model order reduction and passive network synthesis to
form the circuits. Circuits with different topologies are synthesized from
several physical models. This work will give greater understanding to the
physical interpretation of electrical circuits and will enable the development
of more generalised circuits, since the synthesized impedance functions are
generated by considering the physics, not from experimental fitting which may
ignore certain dynamics
Phi-four solitary waves in a parabolic potentia: existence, stability, and collisional dynamics
We explore a φ4 model with an added external parabolic potential term. This term dramatically alters the spectral properties of the system. We identify single and multiple kink solutions and examine their stability features; importantly, all of the stationary structures turn out to be unstable. We complement these with a dynamical study of the evolution of a single kink in the trap, as well as of the scattering of kink and anti-kink solutions of the model. We observe that some of the key characteristics of kink-antikink collisions, such as the critical velocity and the multi-bounce windows, are sensitively dependent on the trap strength parameter, as well as the initial displacement of the kink and antikink.Accepted manuscrip
