©FSRH J Fam Plann Reprod Health Care 2008: 34(2) Why was the change needed? Long-acting reversible contraceptives (LARCs) are underused and many health professionals do not feel confident about how best to provide them. In 2003, Gloucestershire Sexual Health Services were successful in bidding for a programme for the National Primary Care Contracting Collaborative. This was to improve the provi...

Volume 85, Number 4 www.aafp.org/afp American Family Physician 403 The use of long-acting reversible contraceptives (LARCs) has increased from 1.3 to 5.5 percent over the past decade. There are three LARCs available in the United States: the etonogestrel single-rod implant and two types of intrauterine devices (IUDs; copper T380A and levonorgestrel intrauterine system [Mirena]). Rates of uninte...

Introduction Eighty per cent of contraceptive care occurs in the general practice setting. UK Medical Eligibility Criteria provides clear guidelines for the safe provision of appropriate contraception. The Faculty of Sexual and Reproductive Health and the National Institute for Health and Care Excellence offer further recommendations for initiation and continuation of the combined contraceptive...

Oral contraceptives are the most popular reversible method of contraception in the United States. Although most women using oral contraceptives are reliably protected against pregnancy, nearly half of the 3 million unintended pregnancies in the United States annually occur among the 90% of women who use contraception. Recent findings suggest that obesity may reduce the biologic effectiveness of...

we introduce the notion ofstrongly $alpha$-reversible rings which is a strong version of$alpha$-reversible rings, and investigate its properties. we firstgive an example to show that strongly reversible rings need not bestrongly $alpha$-reversible. we next argue about the strong$alpha$-reversibility of some kinds of extensions. a number ofproperties of this version are established. it is shown ...

Effective and productive providers are the key to successful provision of long-acting reversible contraceptives (LARCs). But LARCs demand more of providers than short-acting resupply methods. In addition to sound training, key elements to developing highly productive providers of LARCs include a thorough understanding of the service delivery system context; selecting providers with the most pot...

in this paper, we introduce a class of rings which is a generalization of reversible rings. let r be a ring with identity. a ring r is called central reversible if for any a,b ∈ r, ab=0 implies ba belongs to the center of r. since every reversible ring is central reversible, we study sufficient conditions for central reversible rings to be reversible. we prove that some results of reversible ri...
