Using scanner data, we identify households with a pregnant household member. Within an event study and a dynamic difference-in-differences estimation, we find that during a first pregnancy, households reduce their alcohol purchases by 35%. After pregnancy, purchases of alcohol are 31% lower than before pregnancy. We do not find any effect during the second pregnancy. We argue that lower consumption during pregnancy changes habits and reduces consumption in the long term. We exclude other explanations and comment on policy implications.","PeriodicalId":335359,"journal":{"name":"Obstetrics & Gynecology eJournal","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129093520","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}

In this article, we consider a portfolio-based approach to funding in which multiple distinct ovarian cancer treatment candidates are funded within a single structure. Twenty-five potential early-stage drug development projects were identified for inclusion in a hypothetical portfolio through interviews with gynecological oncologists and leading experts, a review of ovarian cancer-related trials registered in the ClinicalTrials.gov database, and an extensive literature review. The annualized returns of this portfolio were simulated under a purely private sector structure both with and without partial funding from philanthropic grants, and a public-private partnership that included government guarantees. We find that public-private structures of this type can increase expected returns and reduce tail risk, allowing greater amounts of private sector capital to fund early-stage research and development.","PeriodicalId":335359,"journal":{"name":"Obstetrics & Gynecology eJournal","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127172243","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}

In response to the decline in child mortality, women delayed childbearing and had fewer children overall. Fewer women had three or more children, and a larger share remained childless. We present a new theory of the extensive margin response, premised upon improvements in child survival reducing the time women need to achieve their target number of children. This prompts fertility delay and labor market entry which, coupled with wage or fecundity shocks, can result in childlessness. Consistent with these predictions, we find that reductions in child mortality increased women's labor force participation, improved their occupational status and reduced their chances of ever having married. Maternal mortality decline had opposing effects on all of these outcomes.","PeriodicalId":335359,"journal":{"name":"Obstetrics & Gynecology eJournal","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128917118","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}

A Markov model was built in TreeAge® to represent the natural history of bacterial vaginosis. Treatment changes in the face of recurrence without adverse events where modeled separately as a decision tree. The perspective was that of the health system, including all direct costs. All monetary amounts were expressed in Colombian pesos of 2010. The outcome was clinical improvement. Effectiveness, security, persistence and recurrence data were extracted from the literature. The incremental cost-effectiveness ratio was calculated; univariate and probabilistic sensitivity analyses were performed.Results: Both for the general and the particular cases, treatment with vaginal clindamycin as the first choice and tinidazole PO, single dose, to treat recurrence and persistence with adverse events is a dominant strategy because it is less costly and more effective than the other treatment regimes evaluated. Per 1.000 patients, the cost of the dominant alternative is $ 16.795.411 COP with 985,6 clinical improvements in the general case and $ $ 23.979.230 COP with 903,4 clinical improvements in the particular case.Conclusion: Vaginal clindamycin as the first choice for treatment of bacterial vaginosis and tinidazole PO, single dose, to treat recurrence and persistence with adverse events of clindamycin is cost effective in Colombia. The results were robust to variations in the parameters of the model.","PeriodicalId":335359,"journal":{"name":"Obstetrics & Gynecology eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121991884","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}

Physicians report having made substantial changes to their practice in response to the general environment and to liability pressures. Regression analysis finds that liability pressure increases reports of income and practice reductions, but direct effects on actual income and productivity are less clear. Liability pressures may lead to a specialization effect, with some physicians concentrating more in obstetrics and others in gynecological surgery. Overall, the evidence suggests that liability pressure has moderate but significant effects on the specialty.","PeriodicalId":335359,"journal":{"name":"Obstetrics & Gynecology eJournal","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116385572","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}
