      A novel emergency contraceptive is as effective as levonorgestrel when taken within three days of unprotected intercourse, researchers said.&lt;br&gt;
&lt;br&gt;And ulipristal acetate was significantly more effective than the older drug when taken between 72 and 120 hours after intercourse, according to Anna Glasier, DSc, MD, of National Health Service Lothian in Edinburgh, and colleagues.&lt;br&gt;
&lt;br&gt;The finding, from a large randomized single-blind study, establishes ulipristal as an effective alternative to levonorgestrel, which is available in more than 140 countries, Glasier and colleagues said online in &lt;em&gt;The Lancet&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The study is the second in recent days to report that ulipristal is effective up to 120 hours after unprotected sex, about two days longer than levonorgestrel is expected to work. (See &lt;a href=&quot;http://www.medpagetoday.com/OBGYN/Pregnancy/18091&quot; mce_href=&quot;http://www.medpagetoday.com/OBGYN/Pregnancy/18091&quot; target=&quot;_blank&quot;&gt;Novel &apos;Morning-After&apos; Pill Works for Five Days&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;Ulipristal is made by HRA Pharma of Paris, which supported the study. Ulipristal has been given marketing authorization in Europe (under the brand name ellaOne) but is not yet approved in the U.S. Levonorgestrel is marketed here as Plan B One-Step.&lt;/p&gt;
&lt;p&gt;The study enrolled 2,221 women who came to one of 35 participating family planning clinics, requesting emergency contraception within five days after unprotected intercourse.&lt;/p&gt;
&lt;p&gt;The primary endpoint was the pregnancy rate in women who received emergency contraception within the first 72 hours.&lt;/p&gt;
&lt;p&gt;Analysis excluded women lost to follow-up, those over 35, women with unknown follow-up pregnancy status, and those who had re-enrolled in the study  --  leaving a total of 1,696 participants in the so-called efficacy-evaluable population.&lt;/p&gt;
&lt;p&gt;In that group, the researchers found, there were 37 pregnancies  --  15 among those getting 30 milligrams of ulipristal and 22 among those given 1.5 milligrams of levonorgestrel.&lt;/p&gt;
&lt;p&gt;The proportions  --  1.8% for ulipristal versus 2.6% for levonorgestrel  --  differed by 0.8 percentage points, less than the preset noninferiority margin of a one percentage-point difference between the groups, Glasier and colleagues said.&lt;/p&gt;
&lt;p&gt;Outside the primary efficacy-evaluable population, there were 203 women who were treated between 72 and 120 hours after unprotected intercourse.&lt;/p&gt;
&lt;p&gt;Among those women, there were three pregnancies, all in the levonorgestrel group. The difference was significant at &lt;em&gt;P&lt;/em&gt;=0.037.&lt;/p&gt;
&lt;p&gt;Adverse events were reported by 54% of women in the ulipristal group and 56% in the levonorgestrel group, with headache, dysmenorrhea, and nausea being most common, but not significantly different, between the groups.&lt;/p&gt;
&lt;p&gt;Two serious events were thought to be possibly related to medication  --  a case of dizziness in the ulipristal group that cleared up within a day, and a molar pregnancy in the levonorgestrel group.&lt;/p&gt;
&lt;p&gt;The researchers also conducted a meta-analysis, combining the groups in this study with those from a previous head-to-head test of the two drugs to get a combined dataset of 3,445 women, in which there were 60 pregnancies.&lt;/p&gt;
&lt;p&gt;The analysis showed ulipristal prevented more pregnancies at all time points than the older drug. Specifically: &lt;ul&gt; &lt;li&gt;For the first 24 hours, the odds ratio was 0.35 in favor of ulipristal, (95% CI 0.11 to 0.93,&lt;em&gt; P&lt;/em&gt;=0.035).&lt;/li&gt; &lt;li&gt;For the first 72 hours, the odds ratio was 0.58 (95% CI 0.33 to 0.99, &lt;em&gt;P&lt;/em&gt;=0.046).&lt;/li&gt; &lt;li&gt;And for the first 120 hours, the odds ratio was 0.55 (95% CI 0.32 to 0.93, &lt;em&gt;P&lt;/em&gt;=0.025).&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The researchers cautioned that the findings might not generalize to all groups of women. The study took place, they noted, in settings where emergency contraception is available without prescription.&lt;/p&gt;
&lt;p&gt;Also, women on hormonal contraception were excluded from the study, but emergency contraception is often used to treat women who have missed oral contraceptive pills, they noted.&lt;/p&gt;

                     title="Good Results in Poor-Risk Rectal Cancer (CME/CE)"
                     score="0.003"
                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18169?impressionId=1265774201190"
                     
      &lt;p&gt;Patients with high-risk rectal cancer had high response and three-year survival rates on a regimen of preoperative chemotherapy, followed by standard chemoradiation and then surgical resection, according to results of a multicenter study.&lt;/p&gt;
&lt;p&gt;Three-fourths of patients had objective responses to neoadjuvant chemotherapy, increasing to 89% after chemoradiation, researchers reported online in &lt;em&gt;The Lancet Oncology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Additionally, 97% of patients who underwent surgery had microscopically clear surgical margins. At three years, 83% of patients remained alive, including almost 70% who were progression free.&lt;/p&gt;
&lt;p&gt;&quot;Intensification of systemic therapy with neoadjuvant combination chemotherapy before standard treatment is feasible in poor-risk, potentially operable rectal cancer, with acceptable safety and promising long-term outcomes,&quot; David Cunningham, MD, of the Royal Marsden Hospital in Sutton, England, and co-authors concluded.&lt;/p&gt;
&lt;p&gt;&quot;Future development of this multidisciplinary treatment strategy in randomized trials is warranted.&quot;&lt;/p&gt;
&lt;p&gt;Although surgery remains the primary and potentially curative therapy for localized rectal cancer, local recurrence rates as high as 40% have been reported with conventional resection.&lt;/p&gt;
&lt;p&gt;The introduction of standardized surgery and total mesorectal excision reduced local recurrence rates to less than 10%, which has been associated with improved survival, the authors noted.&lt;/p&gt;
&lt;p&gt;Preoperative radiotherapy and then chemoradiation further reduced the risk of local recurrence, but did not improve overall survival compared with surgery alone.&lt;/p&gt;
&lt;p&gt;Combination chemotherapy has led to higher response rates and progression-free survival compared with monotherapy for patients with advanced rectal cancer, the authors continued. Adjuvant chemotherapy containing oxaliplatin (Eloxatin) also has improved outcomes in resected colon cancer.&lt;/p&gt;
&lt;p&gt;Given that oxaliplatin-fluoropyrimidine combinations have become a preferred standard, investigators designed a clinical trial of high-risk rectal cancer to investigate preoperative treatment with oxaliplatin and capecitabine (Xeloda).&lt;/p&gt;
&lt;p&gt;A previous report involving the first 77 patients enrolled in the trial showed substantial tumor regression, rapid improvement in symptoms, and a high rate of clear surgical margins (&lt;em&gt;J Clin Oncol&lt;/em&gt; 2006; 24: 668-74).&lt;/p&gt;
&lt;p&gt;Nine treatment-related cardiac events occurred in eight of the 77 patients, prompting a protocol amendment to exclude patients with a recent history of clinically significant cardiac problems.&lt;/p&gt;
&lt;p&gt;The updated results comprised 105 patients, and only one cardiac event occurred after the change in eligibility criteria, the authors wrote.&lt;/p&gt;
&lt;p&gt;All of the patients had MRI-defined, poor-risk but nonmetastatic rectal cancer. Patients received four cycles of neoadjuvant chemotherapy over 12 weeks, followed by chemoradiotherapy consisting of a total radiation dose of 54 Gy administered over six weeks, plus daily capecitabine.&lt;/p&gt;
&lt;p&gt;After total mesorectal excision, patients received 12 weeks of adjuvant capecitabine.&lt;/p&gt;
&lt;p&gt;The primary endpoint was pathologic complete response, and median follow-up was 55 months.&lt;/p&gt;
&lt;p&gt;Radiologically confirmed response rates were 74% after neoadjuvant chemotherapy and 89% after chemoradiation. Of 97 patients who had surgery, 93 had microscopically clear margins, and 21 of 105 patients had pathologic complete responses.&lt;/p&gt;
&lt;p&gt;Three-year progression-free and overall survival were 68% and 83%, respectively. Among patients who had surgery, three-year, relapse-free survival was 74%.&lt;/p&gt;
&lt;p&gt;&quot;Our findings show the feasibility of neoadjuvant chemotherapy with capecitabine and oxaliplatin before chemoradiotherapy and total mesorectal excision, which accord with the initial results of this study,&quot; the authors declared.&lt;/p&gt;
&lt;p&gt;&quot;High radiological response rates to preoperative treatment were recorded, and the number of pathological complete responses surpassed the prespecified number needed to meet the primary objective of this trial.&quot;&lt;/p&gt;

                     title="SSRIs Affect Breast Milk Production (CME/CE)"
                     score="0.002"
                     href="http://www.medpagetoday.com/Endocrinology/GeneralEndocrinology/tb/18149?impressionId=1265774201190"
                     
      &lt;p&gt;Women taking selective serotonin reuptake inhibitor (SSRI) antidepressants may experience delays in postpartum breast milk production, researchers said.&lt;/p&gt;
&lt;p&gt;Delayed secretory activation occurred in 87.5% of a small group of women taking SSRIs, compared with 43.5% of those not taking the drugs (RR 2, 95% CI 1.51 to 2.67, &lt;em&gt;P&lt;/em&gt;=0.02), according to Aaron M. Marshall, PhD, of the University of Cincinnati.&lt;/p&gt;
&lt;p&gt;The relative risk of delayed activation remained significantly higher (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05) among SSRI users after adjustment for maternal age, obesity, cesarean delivery, infant gestational age, and infant breastfeeding behavior, the researchers reported online in the &lt;em&gt;Journal of Clinical Endocrinology and Metabolism&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;An early breastfeeding difficulty faced by many women, particularly those who are primiparous, is milk secretion delayed beyond 72 hours postpartum.&lt;/p&gt;
&lt;p&gt;These women also are at risk of early cessation of breastfeeding. In fact, only 11% of mothers in the U.S. breastfeed exclusively for the recommended six months.&lt;/p&gt;
&lt;p&gt;Studies in animal models and cell cultures suggested that serotonin (5-HT) is an important local regulator of lactation homeostasis, and the 5-HT transporter is expressed in mammary tissue at the apical membrane of epithelial cells.&lt;/p&gt;
&lt;p&gt;Serotonin is controlled intracellularly by a balance between synthesis and degradation, while extracellularly its availability is controlled through recycling by the 5-HT transporter.&lt;/p&gt;
&lt;p&gt;The 5-HT transporter also is the target for the most commonly prescribed class of antidepressants in the U.S. and other developed countries. These SSRI antidepressants are typically used to treat postpartum depression.&lt;/p&gt;
&lt;p&gt;The investigators conducted in vitro and animal studies to establish that the 5-HT transporter is expressed in breast tissue, particularly in the apical membranes of mammary epithelial cells, and that pharmacologic inhibition of the transporter disrupts tight junctures leading to a local involution-like effect.&lt;/p&gt;
&lt;p&gt;To examine the potential effect of SSRI inhibition on milk production in women, Marshall and colleagues enrolled 431 mothers as part of a longitudinal cohort study examining barriers to early lactation success.&lt;/p&gt;
&lt;p&gt;All were expecting their first live-born infants, had no known absolute contraindication to breastfeeding, and were at least 19 years old.&lt;/p&gt;
&lt;p&gt;Women taking SSRIs were more likely to have scored higher on a depressive symptom scale (as expected), and were somewhat more likely to be obese or to have had a cesarean delivery.&lt;/p&gt;
&lt;p&gt;Participating mothers were visited between 72 and 96 hours after giving birth to assess their breastfeeding experience and to determine the timing of secretory activation, and then seen again one week later.&lt;/p&gt;
&lt;p&gt;Delayed secretory activation was defined as initiation more than 72 hours postpartum.&lt;/p&gt;
&lt;p&gt;Median onset of secretory activation among the SSRI-treated mothers was 85.8 hours compared with 69.1 hours in mothers not using the drugs (&lt;em&gt;P&lt;/em&gt;=0.004).&lt;/p&gt;
&lt;p&gt;Eight women reported regular use of an SSRI medication. Seven experienced definite delayed secretory activation, and the eighth reported activation at 72 hours and therefore did not meet the defined cutoff for delayed activation.&lt;/p&gt;
&lt;p&gt;All women taking SSRIs had experienced secretory activation by their second visit a week after the first interview.&lt;/p&gt;
&lt;p&gt;The researchers noted that most studies on the effects of SSRI use during pregnancy and lactation have focused on the risks for developmental defects or whether the drugs passed into milk during lactation.&lt;/p&gt;
&lt;p&gt;This study, they said, is the first to report data on another important aspect of SSRI use during the peripartum, the effect on milk production.&lt;/p&gt;
&lt;p&gt;They concluded that the risk of delayed secretory activation was twice as great among primiparous women using an SSRI medication, and although the fraction of women taking the drugs was small, the risk was significant and remained so after adjustment for potential confounding factors.&lt;/p&gt;
&lt;p&gt;Further examination of this relationship is needed in larger groups of mothers, the researchers said, and in studies to determine if there are differences among the antidepressant medications.&lt;/p&gt;

                     score="-0.003"

      &lt;p&gt;Pregestational maternal diabetes was associated with an increased risk of a major congenital anomaly, but obesity itself was not, a cross-sectional study found.&lt;/p&gt;
&lt;p&gt;In a multivariable logistic model, the major contributor to a rising rate of congenital anomalies was maternal pregestational diabetes (OR 3.8, 95% CI 2.1 to 6.6), according to Joseph R. Biggio, Jr., MD, and colleagues from the University of Alabama at Birmingham.&lt;/p&gt;
&lt;p&gt;&quot;Because hyperglycemia is a major contributor to developmental malformations, interventions to address obesity and identify women at risk for diabetes and hyperglycemia should be considered in efforts to reduce the occurrence of congenital anomalies,&quot; they wrote in the February issue of &lt;em&gt;Obstetrics &amp;amp; Gynecology.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Maternal obesity has been linked with numerous problems, including preeclampsia, gestational diabetes, fetal and neonatal death, and birth trauma, but scientists have disagreed over whether it also contributes to the risk of fetal malformations, the researchers noted.&lt;/p&gt;
&lt;p&gt;To help settle the issue, Biggio and colleagues used a perinatal database in their university health system that included all women with singletons delivered between 1991 and 2004.&lt;/p&gt;
&lt;p&gt;They divided the cohort into three time periods  --  1991 to 1994, 1995 to 1999, and 2000 to 2004, with a total of 41,902 pregnancies.&lt;/p&gt;
&lt;p&gt;For their primary analysis, they defined maternal obesity as a first prenatal visit weight greater than 200 lb, because during the earlier epochs many women did not have body mass index (BMI) calculated. For their secondary analyses they used BMI greater than 29 kg/m&lt;sup&gt;2&lt;/sup&gt; as the criterion for obesity.&lt;/p&gt;
&lt;p&gt;In each epoch, there were increases in mean maternal weight, mean BMI, the proportion of women weighing more than 200 lb, the proportion with a BMI greater than 29 kg/m&lt;sup&gt;2&lt;/sup&gt;, and the prevalence of pregestational diabetes (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001 for all).&lt;/p&gt;
&lt;p&gt;Univariable analysis determined that the rate of major anomalies, particularly involving the cardiac and pulmonary systems, also increased during each time period.&lt;/p&gt;
&lt;p&gt;But there was no independent association between congenital anomalies and maternal obesity using either definition, during any of the three time periods or during the study overall.&lt;/p&gt;
&lt;p&gt;Although no direct association was seen between congenital malformations and maternal obesity, the investigators reported that the proportion of anomalies that could be attributed to obesity increased from 0% to 23% during the overall study period.&lt;/p&gt;
&lt;p&gt;The proportion of anomalies that could be attributed to diabetes ranged from 58% to 76%.&lt;/p&gt;
&lt;p&gt;Moreover, for obese women with diabetes the proportion of anomalies attributed to diabetes increased sharply, from 48% in the first epoch to 74% in the third epoch.&lt;/p&gt;
&lt;p&gt;In contrast, for the obstetric population as a whole, the population-attributable risk of congenital malformation related to obesity rose from near zero in the first epoch to 6.1% in the third epoch, while that related to diabetes increased from 3.3% to 9.2%, the investigators reported.&lt;/p&gt;
&lt;p&gt;During the course of the study there was a nearly 15-lb increase in maternal weight and a 30% increase in the proportion of women whose BMI exceeded 29 kg/m&lt;sup&gt;2&lt;/sup&gt;.&lt;/p&gt;
&lt;p&gt;There also was a nearly twofold increase in the rate of major anomalies  --  and a 250% increase in the prevalence of diabetes.&lt;/p&gt;
&lt;p&gt;The authors observed that there has been much interest in the effects of maternal obesity on birth defects.&lt;/p&gt;
&lt;p&gt;Although the pathophysiologic basis for this possible association have not been identified, hypotheses have included increased serum insulin, lower levels of folic acid, chronic hypoxia, and increased inflammatory mediators.&lt;/p&gt;
&lt;p&gt;&quot;Our study provides evidence that the defects may not be due solely to the maternal obesity per se but may be due to undiagnosed diabetes,&quot; the investigators wrote.&lt;/p&gt;
&lt;p&gt;From a public health standpoint, the study findings suggest that efforts to reduce the prevalence of congenital anomalies should be focused less on obesity and aimed more closely at correcting hyperglycemia.&lt;/p&gt;
&lt;p&gt;&quot;If euglycemia could be achieved before pregnancy, or at least embryogenesis and organogenesis, the majority of these anomalies could potentially be avoided,&quot; they observed.&lt;/p&gt;
&lt;p&gt;They also suggested that even women of normal weight, but with other diabetes risk factors, could benefit from closer attention to glycemic control.&lt;/p&gt;
&lt;p&gt;A weakness of the study was the fact that detailed data on glycemic control was not available in the perinatal database, &quot;and therefore we cannot comment on the association between glycemic control and anomaly rates,&quot; the investigators wrote.&lt;/p&gt;
