Costs, payments and incentives in family planning programs

A variety of monetary policies regarding contraception exists around the world. These range from high user charges in some countries, to free contraceptives in many, to incentives and disincentives in others. This paper examines these policies, focuses on charges and payments as they existed in early 1988, looks at the consistency of monetary policies within countries, and considers the ethical issues raised by each kind of incentive.Health Monitoring&Evaluation,Adolescent Health,Reproductive Health,Economic Theory&Research,Pharmaceuticals&Pharmacoeconomics

FcγRIIIa Expression on Monocytes in Rheumatoid Arthritis: Role in Immune-Complex Stimulated TNF Production and Non-Response to Methotrexate Therapy

OBJECTIVE:The expression of FcγRIIIa/CD16 may render monocytes targets for activation by IgG-containing immune complexes (IC). We investigated whether FcγRIIIa/CD16 was upregulated in rheumatoid arthritis (RA), associated with TNF production in response to IC-stimulation, and if this predicted response to methotrexate therapy. METHODS:FcγRIIIa/CD16 expression on CD14(low) and CD14++ monocytes was measured by flow cytometry in healthy controls and RA patients (early and long-standing disease). Intracellular TNF-staining was carried out after in vitro LPS or heat-aggregated immunoglobulin (HAG) activation. FcγRIIIa/CD16 expression pre- and post-steroid/methotrexate treatment was examined. RESULTS:Increased FcγRIIIa/CD16 expression on CD14++ monocytes in long-standing RA patients compared to controls was demonstrated (p = 0.002) with intermediate levels in early-RA patients. HAG-induced TNF-production in RA patients was correlated with the percentage of CD14++ monocytes expressing FcγRIIIa/CD16 (p<0.001). The percentage of CD14++ monocytes expressing FcγRIIIa/CD16 at baseline in early DMARD-naïve RA patients was negatively correlated with DAS28-ESR improvement 14-weeks post-methotrexate therapy (p = 0.003) and was significantly increased in EULAR non-responders compared to moderate (p = 0.01) or good responders (p = 0.003). FcγRIIIa/CD16 expression was not correlated with age, presence of systemic inflammation or autoantibody titers. CONCLUSION:Increased FcγRIIIa/CD16 expression on CD14++ monocytes in RA may result in a cell that has increased responsiveness to IC-stimulation. This monocyte subset may contribute to non-response to methotrexate therapy

A Randomized, Placebo-Controlled, Phase II Study of Tetomilast in Active Ulcerative Colitis

BACKGROUND & AIMS: Tetomilast (OPC-6535), a novel thiazole compound, inhibits phosphodiesterase-4 and proinflammatory functions of leukocytes including superoxide production and cytokine release. METHODS: One hundred eighty-six patients with mildly to moderately active ulcerative colitis (Disease Activity Index [DAI] 4-11 points) from 35 centers were randomized to receive an oral, once-daily dose of placebo or tetomilast 25 mg or 50 mg for 8 weeks. RESULTS: Percentages of patients reaching the primary end point (improvement as defined by reduction in DAI > or =3 at week 8) were not significantly different between placebo (35%) and either the 25 mg tetomilast (52%) or the 50 mg tetomilast (39%) groups (intent-to-treat population). Remission rates (DAI 0-1) were 7%, 16%, and 21%, respectively (not significant). Mean reduction in DAI at week 8 was greater in the 25-mg group than under placebo (2.8 +/- 0.4 vs 1.7 +/- 0.36, respectively, P = .041) and approached statistical significance in the 50-mg group (2.8 +/- 0.46, P = .056). A post hoc analysis focusing on patients with high activity scores (baseline DAI 7-11) suggested differences between tetomilast and placebo that will require further investigation. No significant safety concerns were raised. Main adverse effects included gastrointestinal problems (nausea, vomiting) and were preferentially seen in the 50-mg tetomilast group. CONCLUSIONS: This phase II trial of tetomilast in ulcerative colitis did not achieve statistical significance for the primary end point. Secondary end points indicate a potential clinical activity of tetomilast. The post hoc analysis suggests that further clinical development should focus on patients with objective parameters of inflammation

Leveraging population admixture to characterize the heritability of complex traits.

Despite recent progress on estimating the heritability explained by genotyped SNPs (h(2)g), a large gap between h(2)g and estimates of total narrow-sense heritability (h(2)) remains. Explanations for this gap include rare variants or upward bias in family-based estimates of h(2) due to shared environment or epistasis. We estimate h(2) from unrelated individuals in admixed populations by first estimating the heritability explained by local ancestry (h(2)γ). We show that h(2)γ = 2FSTCθ(1 - θ)h(2), where FSTC measures frequency differences between populations at causal loci and θ is the genome-wide ancestry proportion. Our approach is not susceptible to biases caused by epistasis or shared environment. We applied this approach to the analysis of 13 phenotypes in 21,497 African-American individuals from 3 cohorts. For height and body mass index (BMI), we obtained h(2) estimates of 0.55 ± 0.09 and 0.23 ± 0.06, respectively, which are larger than estimates of h(2)g in these and other data but smaller than family-based estimates of h(2)

Tacrolimus for the treatment of fistulas in patients with crohn’s disease: a randomized, placebo-controlled trial

AbstractBackground & Aims:This study determined the effectiveness of tacrolimus for the treatment of Crohn's disease fistulas.Methods:The study was a randomized, double-blind, placebo-controlled, multicenter clinical trial. Forty-eight patients with Crohn's disease and draining perianal or enterocutaneous fistulas were randomized to treatment with oral tacrolimus 0.2 mg · kg−1 · day−1 or placebo for 10 weeks. The primary outcome measure was fistula improvement as defined by closure of ≥50% of particular fistulas that were draining at baseline and maintenance of that closure for at least 4 weeks. A secondary outcome measure was fistula remission as defined by closure of all fistulas and maintenance of that closure for at least 4 weeks.Results:Forty-three percent of tacrolimus-treated patients had fistula improvement compared with 8% of placebo-treated patients (P = 0.004). Ten percent of tacrolimus-treated patients had fistula remission compared with 8% of placebo-treated patients (P = 0.86). Adverse events significantly associated with tacrolimus, including headache, increased serum creatinine level, insomnia, leg cramps, paresthesias, and tremor, were managed with dose reduction.Conclusions:Oral tacrolimus 0.2 mg · kg−1 · day−1 is effective for fistula improvement, but not fistula remission, in patients with perianal Crohn's disease. Adverse events associated with tacrolimus can be managed by dose reduction. Lower doses of tacrolimus should be evaluated
