UPDATED RECOMMENDATIONS FROM THE U.S. PREVENTIVE SERVICES TASK FORCE
The U.S. Preventive Services Task Force (USPSTF) recently published updates to 2 recommendations of interest to readers of this journal: Risk Assessment, Genetic Counseling, and Genetic Testing for BRCA-Related Cancer in Women1 and Screening for Gestational Diabetes Mellitus (GDM).2 These updates include a summary of the research utilized in updating the previous recommendations. The task force asked for public comment as part of their process in developing the recommendations. The USPSTF recommends that primary care providers should screen women with a family history of breast, ovarian, tubal, and peritoneal cancer with a tool designed to screen for mutations of BRCA1 and BRCA2 genes. Specific tools reviewed by the task force are linked to the recommendation statement. Women with positive results should receive genetic counseling and BRCA testing as indicated following counseling. This is a B recommendation with a high certainty of moderate net benefit or moderate certainty of moderate to substantial net benefit.3 Further, the USPSTF recommended against routine genetic counseling and BRCA testing for women without a family history consistent with harmful BRCA1 and BRCA2 mutations. This is a D recommendation, or moderate to high certainty that this service has no benefit or harms outweigh benefits.3 This update affirms the previous USPSTF recommendation with the added recommendation to use risk screening tools. This recommendation applies only to asymptomatic women without a BRCA-related cancer diagnosis. Screening should be considered once women at risk reach the age of consent (age 18), and all women should be assessed periodically for change in family history. Further research, such as comparative effectiveness trials of risk screening approaches and strategies to increase counseling and testing, as well as studies to determine effective methods of genetic counseling in multiple types of settings, and to determine consequences of testing in clinical settings among diverse populations, were recommended. Regarding the update to the recommendation on screening for GDM, the USPSTF recommended screening in asymptomatic women after 24 weeks’ gestation (B recommendation). In addition, the task force determined that the available research evidence was insufficient to assess benefits and harms of screening asymptomatic women prior to 24 weeks’ gestation. (I statement for insufficient evidence, due Published simultaneously in the Journal of Obstetric, Gynecologic, & Neonatal Nursing. 2014;43(3).
1526-9523/09/$36.00 doi:10.1111/jmwh.12208
lack of studies, poor quality, or conflicting evidence).3 This is a change from the previous recommendation in which the task force found insufficient evidence to recommend screening pregnant women before or after 24 weeks’ gestation. The recommendation applies to pregnant women who do not have a preexisting diagnosis of type 1 or type 2 diabetes. The task force suggested consideration of benefits and harms of screening and use of clinical judgment in making decisions about screening individual women with risk factors for type 2 diabetes prior to 24 weeks’ gestation given the insufficient evidence. Additional research was recommended to determine the best threshold for screening and treatment goals, alternative screening methods, and effect of treatment of GDM on longer-term infant and maternal metabolic outcomes. In addition, research is needed to determine if diagnosis and treatment of GDM prior to 24 weeks’ gestation improves shortand long-term maternal and infant outcomes.

EVIDENCE-BASED REVIEWS FROM OTHER SOURCES
Featured Review: Sun X, Zhang D, Zhang W. Effect of metformin on ovulation and reproductive outcomes in women with polycystic ovary syndrome: a meta-analysis of randomized controlled trials. Arch Gynecol Obstet. 2013; 288(2):423–430. The purpose of this systematic review and meta-analysis was to examine the effect of metformin on ovulation and pregnancy in women with polycystic ovary syndrome (PCOS). The review included randomized controlled trials (RCTs) of women with PCOS treated with metformin, clomiphene citrate, or both. The authors searched for articles in English in which ovulation, pregnancy rates, and rates of live birth were compared among study participants. Of the 72 identi356
fied RCTs, 54 did not meet inclusion criteria. As a result, 18 RCTs were included in the review. Treatment regimens included metformin plus clomiphene citrate versus clomiphene citrate, metformin plus clomiphene citrate versus metformin, and metformin versus clomiphene citrate. When the authors compared metformin plus clomiphene citrate vs clomiphene citrate, the results of the meta-analysis indicated the following: the ovulation rate was higher with metformin plus clomiphene citrate (10 trials; odds ratio [OR] 1.27; 95% confidence interval [CI], 1.03–1.56); there were no significant differences in pregnancy rates between the 2 treatment groups (11 trials; OR 1.19; 95% CI, 0.99–1.42); and there was no significant difference between groups for live birth rate (3 trials; OR 0.99; 95% C,I 0.84–1.17). When the authors compared metformin plus clomiphene citrate versus metformin, the results of the metaanalysis indicated the following: the ovulation rate was higher with metformin plus clomiphene citrate than with metformin (2 trials; OR 2.10; 95% CI, 1.89–2.34); the pregnancy rate was greater with metformin plus clomiphene citrate than with metformin (4 trials; OR 2.08; 95% CI, 1.55–2.80); and there was no significant difference between groups for live birth rate (3 trials; OR 1.50; 95% CI, 0.75–3.00). In trials in which the authors compared metformin and clomiphene citrate, the ovulation rate was higher with clomiphene citrate than with metformin (3 trials; OR 0.65; 95% CI, 0 .43–0.995), and there was no difference between treatment groups for pregnancy rate (5 trials; OR 0.86; 95% CI, 0.71–1.13). Comment: The authors concluded that metformin plus clomiphene may be more advantageous than either medication alone for women with PCOS and anovulatory infertility for ovulation and pregnancy. Well-designed multicenter RCTs are needed to confirm this conclusion. Featured review: Einarson TR, Pikko C, Gideon K. Prevalence of nausea and vomiting of pregnancy in the USA: a meta-analysis. J Popul Ther Clin Pharmacol. 2013;20(2):E163–E-170. Nausea and vomiting of pregnancy (NVP) is a common condition of pregnancy, and it most commonly occurs during the first trimester. This condition can be difficult for women, especially the severe form of NVP, hyperemesis gravidarum (HG). Since rates of these 2 related conditions in the United States have not been clarified via a systematic review, the purpose of this review was to calculate point estimates and 95% CIs for NVP and HG in the United States. Peer reviewed studies of women in the United States that included rates of NVP and HG published in the data bases MEDLINE, EMBASE, and Cochrane Libraries from any start date through November 1, 2012 were included. Forty-eight articles were identified, and after duplicates and those that did not otherwise meet inclusion criteria were removed, 33 were included for review. These articles represented 23 studies of 67,602 women that included information on rates of NVP in early pregnancy and 12 studies that included information on HG. The authors found no correlation between rates of NVP or HG and date of publication. Meta-analysis of the 23 studies of 67,602 women indicated a rate of NVP of 68.6% (95% CI, 64.4%-72.8%). The metaanalytic average from 3 studies (5034 women) that reported Volume 59, No. 3, May/June 2014
nausea only was 28.6%, and this average was 24% from 2 studies (136 women) that reported NVP in late pregnancy. Twelve studies representing more than 2 million women had a metaanalytic average rate for HG of 1.2%. Comment: The authors concluded that the rates of NVP and HG were similar to the rates described globally. They urged clinicians to pay attention to the 24% rate of NVP in late pregnancy given the common association with NVP as a first trimester condition. However, the sample reporting this statistic was small. The authors recommend further research to examine the overall resource and cost burden of NVP and the effect of current treatments.

UPDATED RECOMMENDATIONS FROM THE U.S. PREVENTIVE SERVICES TASK FORCE
The U.S. Preventive Services Task Force (USPSTF) recently published updates to 2 recommendations of interest to readers of this journal: Risk Assessment, Genetic Counseling, and Genetic Testing for BRCA-Related Cancer in Women1 and Screening for Gestational Diabetes Mellitus (GDM).2 These updates include a summary of the research utilized in updating the previous recommendations. The task force asked for public comment as part of their process in developing the recommendations. The USPSTF recommends that primary care providers should screen women with a family history of breast, ovarian, tubal, and peritoneal cancer with a tool designed to screen for mutations of BRCA1 and BRCA2 genes. Specific tools reviewed by the task force are linked to the recommendation statement. Women with positive results should receive genetic counseling and BRCA testing as indicated following counseling. This is a B recommendation with a high certainty of moderate net benefit or moderate certainty of moderate to substantial net benefit.3 Further, the USPSTF recommended against routine genetic counseling and BRCA testing for women without a family history consistent with harmful BRCA1 and BRCA2 mutations. This is a D recommendation, or moderate to high certainty that this service has no benefit or harms outweigh benefits.3 This update affirms the previous USPSTF recommendation with the added recommendation to use risk screening tools. This recommendation applies only to asymptomatic women without a BRCA-related cancer diagnosis. Screening should be considered once women at risk reach the age of consent (age 18), and all women should be assessed periodically for change in family history. Further research, such as comparative effectiveness trials of risk screening approaches and strategies to increase counseling and testing, as well as studies to determine effective methods of genetic counseling in multiple types of settings, and to determine consequences of testing in clinical settings among diverse populations, were recommended. Regarding the update to the recommendation on screening for GDM, the USPSTF recommended screening in asymptomatic women after 24 weeks’ gestation (B recommendation). In addition, the task force determined that the available research evidence was insufficient to assess benefits and harms of screening asymptomatic women prior to 24 weeks’ gestation. (I statement for insufficient evidence, due Published simultaneously in the Journal of Obstetric, Gynecologic, & Neonatal Nursing. 2014;43(3).
1526-9523/09/$36.00 doi:10.1111/jmwh.12208
lack of studies, poor quality, or conflicting evidence).3 This is a change from the previous recommendation in which the task force found insufficient evidence to recommend screening pregnant women before or after 24 weeks’ gestation. The recommendation applies to pregnant women who do not have a preexisting diagnosis of type 1 or type 2 diabetes. The task force suggested consideration of benefits and harms of screening and use of clinical judgment in making decisions about screening individual women with risk factors for type 2 diabetes prior to 24 weeks’ gestation given the insufficient evidence. Additional research was recommended to determine the best threshold for screening and treatment goals, alternative screening methods, and effect of treatment of GDM on longer-term infant and maternal metabolic outcomes. In addition, research is needed to determine if diagnosis and treatment of GDM prior to 24 weeks’ gestation improves shortand long-term maternal and infant outcomes.

EVIDENCE-BASED REVIEWS FROM OTHER SOURCES
Featured Review: Sun X, Zhang D, Zhang W. Effect of metformin on ovulation and reproductive outcomes in women with polycystic ovary syndrome: a meta-analysis of randomized controlled trials. Arch Gynecol Obstet. 2013; 288(2):423–430. The purpose of this systematic review and meta-analysis was to examine the effect of metformin on ovulation and pregnancy in women with polycystic ovary syndrome (PCOS). The review included randomized controlled trials (RCTs) of women with PCOS treated with metformin, clomiphene citrate, or both. The authors searched for articles in English in which ovulation, pregnancy rates, and rates of live birth were compared among study participants. Of the 72 identi356
fied RCTs, 54 did not meet inclusion criteria. As a result, 18 RCTs were included in the review. Treatment regimens included metformin plus clomiphene citrate versus clomiphene citrate, metformin plus clomiphene citrate versus metformin, and metformin versus clomiphene citrate. When the authors compared metformin plus clomiphene citrate vs clomiphene citrate, the results of the meta-analysis indicated the following: the ovulation rate was higher with metformin plus clomiphene citrate (10 trials; odds ratio [OR] 1.27; 95% confidence interval [CI], 1.03–1.56); there were no significant differences in pregnancy rates between the 2 treatment groups (11 trials; OR 1.19; 95% CI, 0.99–1.42); and there was no significant difference between groups for live birth rate (3 trials; OR 0.99; 95% C,I 0.84–1.17). When the authors compared metformin plus clomiphene citrate versus metformin, the results of the metaanalysis indicated the following: the ovulation rate was higher with metformin plus clomiphene citrate than with metformin (2 trials; OR 2.10; 95% CI, 1.89–2.34); the pregnancy rate was greater with metformin plus clomiphene citrate than with metformin (4 trials; OR 2.08; 95% CI, 1.55–2.80); and there was no significant difference between groups for live birth rate (3 trials; OR 1.50; 95% CI, 0.75–3.00). In trials in which the authors compared metformin and clomiphene citrate, the ovulation rate was higher with clomiphene citrate than with metformin (3 trials; OR 0.65; 95% CI, 0 .43–0.995), and there was no difference between treatment groups for pregnancy rate (5 trials; OR 0.86; 95% CI, 0.71–1.13). Comment: The authors concluded that metformin plus clomiphene may be more advantageous than either medication alone for women with PCOS and anovulatory infertility for ovulation and pregnancy. Well-designed multicenter RCTs are needed to confirm this conclusion. Featured review: Einarson TR, Pikko C, Gideon K. Prevalence of nausea and vomiting of pregnancy in the USA: a meta-analysis. J Popul Ther Clin Pharmacol. 2013;20(2):E163–E-170. Nausea and vomiting of pregnancy (NVP) is a common condition of pregnancy, and it most commonly occurs during the first trimester. This condition can be difficult for women, especially the severe form of NVP, hyperemesis gravidarum (HG). Since rates of these 2 related conditions in the United States have not been clarified via a systematic review, the purpose of this review was to calculate point estimates and 95% CIs for NVP and HG in the United States. Peer reviewed studies of women in the United States that included rates of NVP and HG published in the data bases MEDLINE, EMBASE, and Cochrane Libraries from any start date through November 1, 2012 were included. Forty-eight articles were identified, and after duplicates and those that did not otherwise meet inclusion criteria were removed, 33 were included for review. These articles represented 23 studies of 67,602 women that included information on rates of NVP in early pregnancy and 12 studies that included information on HG. The authors found no correlation between rates of NVP or HG and date of publication. Meta-analysis of the 23 studies of 67,602 women indicated a rate of NVP of 68.6% (95% CI, 64.4%-72.8%). The metaanalytic average from 3 studies (5034 women) that reported Volume 59, No. 3, May/June 2014
nausea only was 28.6%, and this average was 24% from 2 studies (136 women) that reported NVP in late pregnancy. Twelve studies representing more than 2 million women had a metaanalytic average rate for HG of 1.2%. Comment: The authors concluded that the rates of NVP and HG were similar to the rates described globally. They urged clinicians to pay attention to the 24% rate of NVP in late pregnancy given the common association with NVP as a first trimester condition. However, the sample reporting this statistic was small. The authors recommend further research to examine the overall resource and cost burden of NVP and the effect of current treatments.
