As donor contributions for HIV/AIDS stagnate globally, national governments must seek ways to improve use of existing resources through interventions to drive efficiency at the facility level. But program managers lack routine information on unit expenditures at points of care, and higher-level planners are unable to assess resource use in the health system. Thus, managers cannot measure current levels of technical efficiency, and are unable to evaluate effectiveness of interventions to increase technical efficiency.

Ras requires cell membrane association for its biological activity, and this requires the posttranslational modification of Ras with an isoprenyl group by farnesyltransferase (FTase) or geranylgeranyltransferase (GGTase). We hypothesized that inhibition of FTase using FTase inhibitor (FTI)-277 would attenuate allergic asthma by depleting membrane-associated Ras.

However, it is not widely available in developing countries, largely due to the high price of existing products. Medicines360 plans to introduce its new, more affordable LNG IUS in Kenya.

An estimated 5%-10% of the 300 million people worldwide who suffer from asthma have a severe form. Patients with eosinophilic airway inflammation represent approximately 40%-60% of this severe asthmatic population.

We hypothesized that pravastatin delivered intratracheally would be quantifiable in lung tissues using mass spectrometry, achieve high drug concentrations in the lung with minimal systemic absorption, and mitigate airway inflammation and structural changes induced by ovalbumin. Male BALB/c mice were sensitized to ovalbumin (OVA) over 4 weeks, then exposed to 1% OVA aerosol or filtered air (FA) over 2 weeks.

Even within countries that have achieved increases in contraceptive prevalence, use remains low among some population subgroups.

The objective of this study was to assess the 5-year data regarding spinal mobility, physical function and HRQoL in patients with AS who participated in the Adalimumab Trial Evaluating Long-term Efficacy and Safety for AS (ATLAS) study.
Methods: Patients received blinded adalimumab 40 mg or placebo every other week for 24 weeks, then open-label adalimumab for up to 5 years.

Asthma is a complex syndrome that affects an estimated 26 million people in the United States but gaps exist in the recognition and management of asthmatic subgroups. This article proposes alternative approaches for future treatments of adult obese asthmatics who do not respond to standard controller therapies, drawing parallels between seemingly disparate therapeutics through their common signaling pathways. How metformin and statins can potentially improve airway inflammation is described and supplements are suggested.

One way to fill this gap is for community health workers (CHWs) to provide injectable contraceptives, an intervention for which there is growing evidence and international support. In 2009, with approval from the Government of Zambia (GoZ), FHI 360 collaborated with ChildFund Zambia to design and implement such an intervention as part of its existing CHW family planning program.

We tested whether two ACEi (captopril and enalapril), differing in a thiol group, protected human umbilical vein endothelial cells (HUVEC) from cytotoxicity induced by polymorphonuclear neutrophils (PMN) in vitro, when cells were activated by tumour necrosis factor-α (TNFα) or the arachidonate derivative lipoxin-A4 (LXA4 ), using separate cytotoxicity pathways. When (51) Cr labelled HUVEC were treated with captopril (0-500 μm) or enalapril (0-100 μm) for 2 h and then activated by TNFα (100 ng/ml) for 24 h, a significant, dose-dependent reduction of (51) Cr release was observed.

Control of airway inflammation is critical in asthma treatment. Soluble epoxide hydrolase (sEH) has recently been demonstrated as a novel therapeutic target for treating inflammation, including lung inflammation. We hypothesized that pharmacological inhibition of sEH can modulate the inflammatory response in a murine ovalbumin (OVA) model of asthma.

Collagen has been used in a wide range of tissue engineering applications; however, due to its low mechanical properties its use is limited to non load-bearing applications without further manipulation using methods such as cross-linking or mechanical compression. Here, it was hypothesised that the addition of soluble elastin to a collagen hydrogel could improve its mechanical properties.

Methods: In this multicentre, two-arm, parallel, randomised, active-controlled, open-label trial, rheumatoid arthritis patients with <1 year symptom duration were recruited from 15 rheumatology clinics in Sweden between October 2002 and December 2005. After 3-4 months of methotrexate monotherapy, patients not achieving low disease activity were randomised to addition of infliximab or sulfasalazine+hydroxychloroquine (conventional treatment group).
Nanocarriers can deliver a wide variety of drugs, target them to sites of interest, and protect them from degradation and inactivation by the body. They have the capacity to improve drug action and decrease undesirable systemic effects. We have previously developed a well-defined non-toxic PEG-dendritic block telodendrimer for successful delivery of chemotherapeutics agents and, in these studies, we apply this technology for therapeutic development in asthma.

Here, we investigated airway inflammation and hyperresponsiveness using a mouse ovalbumin exposure model of asthma assessing the effects of consuming EPA (1.5% wt/wt), DHA (1.

These effects are not limited to the respiratory system; increases in acute cardiovascular events have been observed. The development of extrapulmonary illnesses has led to interest in determining whether particles move out of the lungs and whether transport of particles differs for asthmatic individuals.

These drugs have been shown to lead to superior radiological outcomes compared with a combination of conventional disease-modifying antirheumatic drugs over 2 years.
Objective: To investigate whether radiological superiority translates into better work loss outcomes.
Background: Rapid scale-up of voluntary medical male circumcision (VMMC) is needed to realize potential reductions in HIV incidence in sub-Saharan Africa. New disposable VMMC devices such as the Shang Ring may offer several advantages over standard surgery, including lower costs.
Methods: We compared direct costs of the Shang Ring and dorsal slit techniques for delivery of VMMC in the context of a randomized-controlled trial carried out in Zambia in 2011.
Objective: To compare EuroQol 5-Dimensions (EQ-5D) utility and quality-adjusted life-years (QALYs) in patients with early, methotrexate (MTX) refractory rheumatoid arthritis (RA), randomised to addition of infliximab (IFX) or sulfasalazine and hydroxychloroquine (SSZ+HCQ).
Methods: RA-patients with symptoms <1 year were enrolled between 2002 and 2005 at 15 Swedish centres. After 3-4 months of MTX monotherapy, patients with a remaining DAS28>3.
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death. The statin drugs may have therapeutic potential in respiratory diseases such as COPD, but whether they prevent bronchial epithelial injury is unknown. We hypothesised that simvastatin attenuates acute tobacco smoke-induced neutrophilic lung inflammation and airway epithelial injury.

Here we report the 2 year follow-up assessment.
Methods: In this randomised, non-blinded, parallel-group trial, we enrolled adult patients older than 18 years with rheumatoid arthritis and a symptom duration of less than 1 year from 15 rheumatology units in Sweden between December, 2002 and December, 2006.
Objectives: Cyclophosphamide (CYC) and corticosteroids are generally considered standard induction therapy for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). However, a subset of patients are refractory or intolerant to this treatment. Rituximab, a chimeric anti-CD20 antibody, has emerged as a second-line therapy, although controlled studies are scarce in patients with relapsing or refractory disease.
