Grossman","doi":"10.1586/17474108.2013.825477","DOIUrl":"https://doi.org/10.1586/17474108.2013.825477","url":null,"abstract":"After more than a decade, the battle surrounding over-the-counter (OTC) access to emergency contraception (EC) in the USA has finally been won. Science trumped politics in the end, and women are now able to obtain OTC EC on the shelf, and not just in a pharmacy, but in other retail stores as well. Building on this victory, reproductive health advocates in the USA are now beginning to set their sights on the next advance in contraceptive access: OTC oral contraceptive pills (OCPs). OTC access to OCPs might sound revolutionary in the USA or Western Europe, but it is the reality for most women in the world. A recent analysis of prescription requirements for OCPs in 147 countries found that women can easily obtain pills in pharmacies without a prescription in most of these countries [1]. In only 31% of countries, a prescription is required to obtain OCPs. In 24% of countries, pills are formally available OTC, while some countries (8%) require a woman to undergo health screening by a pharmacy worker before pills are provided without a prescription. In 38% of countries, OCPs are technically in a class of drug that should require a prescription, but they are generally available informally in pharmacies without a prescription. A growing body of evidence from some of these other countries, as well as experimental research from the USA, indicate that OTC access to OCPs is both safe and effective. The main safety question is whether women can accurately identify contraindications to use without the assistance of a clinician. In two studies in the USA, women were able to accurately identify contraindications to combined OCPs using a simple checklist, although in one study, 7% of women had unrecognized hypertension that was not identified until they saw a clinician [2,3]. Women were much more accurate at identifying contraindications to progestinonly OCPs, a formulation that has fewer and rarer contraindications compared to combined OCPs [4]. OTC access to OCPs also may help women with method continuation by making it easier to get more supply. In a study from El Paso, Texas, women who obtained OCPs in Mexican pharmacies OTC were significantly less likely to discontinue their method over 9 months compared to women who obtained OCPs by prescription in clinics [5]. In another study from Kuwait, where OCPs are available without a prescription, OTC users had similar method continuation compared to women who used OCPs under the supervision of a physician [6]. Importantly, US women are interested in OTC access to OCPs. A recent nationally representative survey found that 37% of women at risk of unintended pregnancy said they would be likely to use an OTC OCP if one were available [7]. Interest was highest among current OCP users, of which 59% said they were likely to use an OTC pill. In addition, 28% of women using no method and 33% of those using a less effective method, such as condoms","PeriodicalId":12242,"journal":{"name":"Expert Review of Obstetrics & Gynecology","volume":"25 1","pages":"389-391"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91070367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The very poor pregnancy rates found in many studies of IVF-ET in this population seems to be related to the use of high-dosage FSH stimulation. The presence of significant elevated FSH levels leave many women more prone to FSH receptor downregulation. The best ‘hypothesis’ to fit the poor success rate found with high FSH stimulation is that FSH receptor downregulation leads to an insufficient production of a factor needed to prevent non-disjunction of chromosomes, leading to the creation of embryos with a high percentage of aneuploidy. Mild stimulation, to a reasonable degree obviates the problem with FSH receptors and results in the production of live healthy babies.","PeriodicalId":12242,"journal":{"name":"Expert Review of Obstetrics & Gynecology","volume":"78 1","pages":"401-415"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81211219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since treatment of threatened preterm delivery has limited effectiveness, the focus is on primary and secondary prevention. Identification of risk indicators in early pregnancy provides the opportunity for preventive measures. To determine the potential impact of individualized risk indicators on the prediction of preterm birth, we reviewed the literature on this topic. Risk indicators for spontaneous preterm birth can be categorized in five groups; characteristics of the individual (ethnicity/race), characteristics of the fetus (fetal gender fetal number and chorionicity), obstetric history (history of preterm birth), modifiable risk indicators (social status, life style, infection) and signs of early labour; potential predictors (sonographic markers, biomarkes).

Appropriate technique is essential for correct results. Factors that affect the value of CL in the prediction of spontaneous preterm delivery include gestational age, patient obstetrical and medical history, symptoms and the number of fetuses. The value of CL consists of identifying high-risk women for therapeutic strategies, to reduce the rate of spontaneous preterm birth, such as progestogens, cervical cerclage and more recently, cervical pessary. Progestogens and cervical cerclage are more effective in gestations with prior preterm birth.","PeriodicalId":12242,"journal":{"name":"Expert Review of Obstetrics & Gynecology","volume":"4 1","pages":"345-355"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86368095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
