      &lt;p&gt;A flagon of ale may indeed be a good source of dietary silicon, a recent study showed, but experts say any attempt to link beer drinking to bone health is not based on scientific data.&lt;/p&gt;
&lt;p&gt;The study of 100 commercial beers in the February issue of the &lt;em&gt;Journal of the Science of Food and Agriculture&lt;/em&gt;, by Charles Bamforth, PhD, DSc, and Troy Casey, of the University of California Davis, examined the silicon content that results from different ingredients and brewing processes.&lt;/p&gt;
&lt;p&gt;Although a press release issued with the study prominently mentioned the link between silicon and bone health, the study itself did not look at bone mineral density or analyze any patient data at all, according to several researchers contacted by &lt;em&gt;MedPage Today&lt;/em&gt; and ABC News.&lt;/p&gt;
&lt;p&gt;The authors wrote that they explored the silicon content in beer because the popular beverage has been identified as one of the richest potential sources of dietary silicon in the Western diet. The average intake is 20 to 50 mg/day.&lt;/p&gt;
&lt;p&gt;The beers sampled contained an average of 29.4 mg/L of silicon, with a range of 6.4 to 56.4 mg/L. Beers made from a barley-based grist (as opposed to wheat-based beers ) and brews containing more hops had the highest silicon levels.&lt;/p&gt;
&lt;p&gt;The beer type with the overall highest silicon level was India Pale Ale, with an average of 41.2 mg/L. Other ales came in second with 32.8 mg/L.&lt;/p&gt;
&lt;p&gt;Nonalcoholic beers, light lagers, and wheat beers had the least silicon.&lt;/p&gt;
&lt;p&gt;In the end, the authors concluded that &quot;beer is a substantial source of silicon in the diet&quot; and that &quot;beers containing high levels of malted barley and hops are richest in silicon,&quot; but they did not attempt to establish a link between beer drinking and bone health.&lt;/p&gt;
&lt;p&gt;Experts contacted for comment on the study also cautioned the public against establishing any such connection.&lt;/p&gt;
&lt;p&gt;&quot;To conclude any bone health benefits from this study would require a great leap,&quot; Tim Byers, MD, MPH, deputy director of the University of Colorado Cancer Center in Aurora, wrote in an e-mail.&lt;/p&gt;
&lt;p&gt;Other researchers noted that previous studies have shown an association between alcohol consumption and an increased risk of fracture.&lt;/p&gt;
&lt;p&gt;That&apos;s probably because of a greater chance of falling after drinking, according to Walter Willett, MD, DrPH, of the Harvard School of Public Health.&lt;/p&gt;
&lt;p&gt;In fact, Stephen Richardson, MD, an endocrinologist at NYU Langone Medical Center, noted that &quot;alcohol consumption is a risk factor for osteoporosis.&quot;&lt;/p&gt;
&lt;p&gt;Still, there is some evidence supporting a positive link between overall dietary silicon and bone health.&lt;/p&gt;
&lt;p&gt;A 2004 cross-sectional study in the &lt;em&gt;Journal of Bone and Mineral Research&lt;/em&gt; that used data from the Framingham Offspring cohort found a significant association between greater dietary silicon intake, including that from beer, and higher bone mineral density in the hip in men and premenopausal women.&lt;/p&gt;
&lt;p&gt;The researchers concluded: &quot;These findings suggest that higher dietary silicon intake in men and younger women may have salutary effects on skeletal health, especially cortical bone health, that has not been previously recognized.&quot;&lt;/p&gt;
&lt;p&gt;Another study by the same group published last year in the &lt;em&gt;American Journal of Clinical Nutrition&lt;/em&gt; found that moderate consumption of alcohol, including beer, wine, and liquor, was associated with higher bone mineral density in men and postmenopausal women.&lt;/p&gt;
&lt;p&gt;However, it also showed that men who drank too much liquor were more likely to have lower spine and hip bone mineral density.&lt;/p&gt;
&lt;p&gt;The relationship between beer and bone mineral density appeared to be mediated by silicon, the researchers concluded.&lt;/p&gt;
&lt;p&gt;Bottom line: considering the increased fracture risk and the various other problems associated with drinking too much alcohol, experts agree that guzzling beer is not strategy for improving bone health.&lt;/p&gt;
&lt;p&gt;&quot;In the absence of bone density values or preferably fracture incidence, it would be premature to tout beer as a preventative or treatment,&quot; Richardson said.&lt;/p&gt;
&lt;p&gt;David Katz, MD, MPH, of the Yale School of Public Health, agreed.&lt;/p&gt;
&lt;p&gt;&quot;This is NOT a reason to drink beer,&quot; he said in an e-mail. &quot;This is simply a bit of good news for those who do drink beer already  --  yours truly among them!&quot;&lt;/p&gt;

                     score="-0.001"

      &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;

                     score="-0.002"
                     href="http://www.medpagetoday.com/OBGYN/DomesticViolence/tb/18085?impressionId=1265782264589"
                     
      &lt;p&gt;Pregnant African-American women who received counseling to improve their physical and psychological health and safety were less likely to be the victims of domestic violence during pregnancy and postpartum, a new study found.&lt;/p&gt;
&lt;p&gt;Women who received the cognitive and behavioral integrated intervention were less likely to experience recurrent episodes of intimate partner violence victimization (OR 0.48, 95% CI 0.29 to 0.80), according to a report in the Jan. 21 issue of &lt;em&gt;Obstetrics &amp;amp; Gynecology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Counseled women who had reported previous minor intimate partner violence were significantly less likely to experience further episodes during pregnancy (OR 0.48, 95% CI 0.26 to 0.86) and after they gave birth (OR 0.56, 95% CI 0.34 to 0.93).&lt;/p&gt;
&lt;p&gt;Furthermore, counseled women were less likely to give birth very preterm (&amp;lt;33 weeks gestation) than mothers who received no counseling (1.5% versus 6.6% respectively; &lt;em&gt;P&lt;/em&gt;=0.03), and the babies of counseled women had a longer mean gestational age at delivery.&lt;/p&gt;
&lt;p&gt;&quot;A relatively brief intervention during pregnancy had discernible effects on intimate partner violence and pregnancy outcomes,&quot; Michele Kiely, DrPH, of Eunice Kennedy Shriver National Institute of Child Health and Human Development, and colleagues wrote.&lt;/p&gt;
&lt;p&gt;&quot;Screening for intimate partner violence as well as other psychosocial and behavioral risks and incorporating similar interventions in prenatal care is strongly recommended.&quot;&lt;/p&gt;
&lt;p&gt;Intimate partner violence is a pattern of assault and coercion that includes the threat or infliction of physical, sexual, or psychological abuse.&lt;/p&gt;
&lt;p&gt;Approximately 4.8 million episodes of intimate partner violence occur every year in the U.S. in women 18 years and older, according to the CDC.&lt;/p&gt;
&lt;p&gt;Victims are at higher risk for a range of psychobehavioral and health problems, including complications during pregnancy and adverse pregnancy outcomes, such as preterm delivery and low birth weight.&lt;/p&gt;
&lt;p&gt;Kiely and colleagues set out to determine whether a cognitive behavioral intervention administered during pregnancy could reduce intimate partner violence and improve birth outcomes in a population of African-American residents of Washington, DC.&lt;/p&gt;
&lt;p&gt;Of the 1,044 women enrolled in the study between July 2001 and October 2003, 521 were randomly assigned to receive the intervention and 523 to receive usual care. At an initial interview, 336 of the women reported intimate partner violence victimization in the past year, evenly divided between the intervention group and usual care.&lt;/p&gt;
&lt;p&gt;The women in the intervention group received individually tailored counseling and information that addressed the problems they reported.&lt;/p&gt;
&lt;p&gt;The counselors provided information about the types of abuse and the cycle of violence and assessed the level of danger to which the women were exposed.&lt;/p&gt;
&lt;p&gt;They discussed preventive options the women might consider, such as filing a protection order, and the development of a safety plan. The women also received a list of community resources and information on the health risks of smoking and how to cope with depression.&lt;/p&gt;
&lt;p&gt;The complete intervention included eight prenatal sessions delivered during routine prenatal care visits, and researchers conducted follow-up interviews over the phone with the women.&lt;/p&gt;
&lt;p&gt;They found that women in the intervention group who had previously experienced severe intimate partner violence showed a significant reduction in episodes after giving birth (OR 0.39, 95% CI 0.18 to 0.82) and that women who experienced physical violence specifically showed significant reductions by their first follow-up prenatal visit (OR 0.49, 95% CI 0.27 to 0.91) and postpartum (OR 0.47, 95% CI 0.27 to 0.82).&lt;/p&gt;
&lt;p&gt;&quot;There is evidence that this intervention for pregnant African-American women reduced intimate partner violence victimization during pregnancy and improved pregnancy outcome,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;If generalizable, our results should encourage healthcare providers and third party payers to go beyond screening for psychosocial and behavioral risks to providing services during prenatal care to address such risks. The potential cost savings associated with reduction of births within the highest risk category may be substantial.&quot;&lt;/p&gt;
&lt;p&gt;The authors cautioned that the study was not designed to test whether the intervention was effective at reducing adverse pregnancy outcomes but rather focused on reducing psychobehavioral risks.&lt;/p&gt;
&lt;p&gt;They also noted that only 59% of the women in the intervention group completed all eight sessions, indicating that as a group they were only modestly committed to participating in the program.&lt;/p&gt;
&lt;p&gt;Further improvements to the intervention strategy could be made to address other issues, such as alcohol and drug use, they wrote. &quot;Had we addressed these, we might have been even more successful,&quot; they concluded.&lt;/p&gt;
