      Genetic variants involved in regulating inflammation and the extracellular matrix may increase the risk of preterm birth, researchers say.&lt;br&gt;
&lt;br&gt;A single nucleotide polymorphism (SNP) in fetal interleukin-6 (&lt;em&gt;ILR6&lt;/em&gt;) and another in maternal tissue inhibitor of metalloproteinase 2 (&lt;em&gt;TIMP2&lt;/em&gt;) were each associated with a twofold increased risk of spontaneous preterm birth.&lt;br&gt;
&lt;br&gt;Roberto Romero, MD, of the National Institute of Child Health and Human Development, and colleagues reported the findings at the Society for Maternal-Fetal Medicine meeting in Chicago.&lt;/p&gt;
&lt;p&gt;&quot;The genetic makeup of both mother and fetus can contribute to the risk of premature labor,&quot; Romero told &lt;em&gt;MedPage Today&lt;/em&gt;. &quot;Our discovery . . . helps explain why some mothers have premature labor and delivery despite having optimal prenatal care.&quot;&lt;/p&gt;
&lt;p&gt;Inflammatory hormones have been shown to play a role in the labor process, and previous studies have found that a third of preterm infants are born to mothers with a silent amniotic infection.&lt;/p&gt;
&lt;p&gt;Now, the findings suggest that individual genetic variation involved in that inflammatory response may account for discrepancies in preterm births.&lt;/p&gt;
&lt;p&gt;&quot;We have a large body of evidence that proves silent infections are a frequent and important cause of premature labor,&quot; Romero said. &quot;These infections can also attack the fetus before it is born.&quot;&lt;/p&gt;
&lt;p&gt;He explained that the mother&apos;s hormones initiate the onset of labor to get rid of the infected tissue, and the fetus seeks to exit a hostile intrauterine environment that threatens its survival.&lt;/p&gt;
&lt;p&gt;To look at the mechanisms by which this process occurs, Romero and colleagues conducted a case-control study of mothers in Chile to assess genetic factors that could predispose women to spontaneous preterm labor and delivery.&lt;/p&gt;
&lt;p&gt;Patients who delivered prior to 37 weeks gestation served as cases, while women who delivered a normal neonate at term served as controls. There were 223 mothers and 179 fetuses in the case group, and 599 mothers and 628 fetuses in the control group.&lt;/p&gt;
&lt;p&gt;The researchers subsequently examined 190 candidate genes and 775 SNPs.&lt;/p&gt;
&lt;p&gt;They found that the strongest fetal single-locus association with risk of spontaneous preterm birth was in &lt;em&gt;ILR6&lt;/em&gt;, (OR 2.07, 95% CI 1.42 to 3.02,&lt;em&gt; P&lt;/em&gt;=0.0001).&lt;/p&gt;
&lt;p&gt;The strongest maternal single-locus association with spontaneous preterm labor and delivery was in tissue inhibitor of metalloproteinase &lt;em&gt;TIMP2&lt;/em&gt; (OR 1.98, 95% CI 1.38 to 2.83, &lt;em&gt;P&lt;/em&gt;=0.0002). This gene is involved in regulating the extracellular matrix, which holds cells within tissues.&lt;/p&gt;
&lt;p&gt;The associations remained significant after controlling for multiple comparisons, Romero said.&lt;/p&gt;
&lt;p&gt;Global haplotype analysis also indicated an association between a fetal DNA variant in insulin-like growth factor 2 (&lt;em&gt;P&lt;/em&gt;=0.004) as well as maternal alpha 3 type IV collagen isoform 1 (&lt;em&gt;COL4A3&lt;/em&gt;) (&lt;em&gt;P&lt;/em&gt;=0.007).&lt;/p&gt;
&lt;p&gt;&quot;Some women and fetuses carry gene variants that predispose them to the early onset of labor,&quot; Romero said.&lt;/p&gt;

                     score="0.009"
                     href="http://www.medpagetoday.com/ProductAlert/DevicesandVaccines/tb/18229?impressionId=1265790468843"
                     
      &lt;p&gt;WASHINGTON  --  The FDA has updated labels of the HIV drug didanosine (Videx and Videx EC) to include warnings for potentially serious liver damage.&lt;/p&gt;
&lt;p&gt;Although these cases are rare, the drug may cause noncirrhotic hypertension in patients, a potentially fatal complication which the FDA discovered through 42 postmarket, adverse event reports.&lt;/p&gt;
&lt;p&gt;Of those patients, three required liver transplant and four died. Two deaths were caused by esophageal hemorrhage, while two more were caused by progressive liver failure.&lt;/p&gt;
&lt;p&gt;One patient suffered multiorgan failure, cerebral hemorrhage, sepsis, and lactic acidosis.&lt;/p&gt;
&lt;p&gt;The FDA said in a statement that it chose not to recall the drug because it believes its benefits outweigh potential risks, but advised that treatment decisions be made on an individual basis between healthcare professionals and patients.&lt;/p&gt;
&lt;p&gt;The agency added that causal association is difficult to determine in postmarket reports, but that alternative causes of the hypertension were ruled out in well-documented cases.&lt;/p&gt;
&lt;p&gt;Healthcare professionals who determine didanosine is effective in treating a patient should monitor that patient for the development of portal hypertension and esophageal varices, the agency said.&lt;/p&gt;
&lt;p&gt;Didanosine is used in combination with other HIV medications to help maintain CD4 cells in patients.&lt;/p&gt;
&lt;p&gt;The drug already has a black box warning for lactic acidosis and hepatomegaly with steatosis.&lt;/p&gt;
&lt;p&gt;Like the antiretroviral agents hydroxyurea and ribavirin, didanosine has been associated with the development of liver toxicity.&lt;/p&gt;

                     score="-0.002"
                     href="http://www.medpagetoday.com/OBGYN/DomesticViolence/tb/18085?impressionId=1265790468843"
                     
      &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;

                     score="-0.002"
                     href="http://www.medpagetoday.com/HIVAIDS/HIVAIDS/tb/18071?impressionId=1265790468843"
                     
      &lt;p&gt;Treating herpes has no effect on the transmission of HIV among discordant couples, researchers said.&lt;/p&gt;
&lt;p&gt;The lack of efficacy was found in a large, randomized clinical trial despite significant reductions in HIV viral load among those treated for herpes simplex-2 (HSV-2), according to Connie Celum, MD, of the University of Washington, and colleagues.&lt;/p&gt;
&lt;p&gt;Researchers will have to look for new ways to prevent transmission among discordant couples (in which one partner has HIV and the other does not), Celum and colleagues concluded online in the&lt;em&gt; New England Journal of Medicine.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;The study comes after earlier trials also showed that treating HSV-2 with the antiviral acyclovir (Zovirax) did not lower the risk of getting HIV. (See &lt;a href=&quot;http://www.medpagetoday.com/HIVAIDS/HIVAIDS/9884&quot; mce_href=&quot;http://www.medpagetoday.com/HIVAIDS/HIVAIDS/9884&quot; target=&quot;_blank&quot;&gt;Herpes Treatment No Help in Preventing HIV&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;The trials  --  and the current study  --  had their origins in epidemiological and laboratory observations that having an HSV-2 infection increased the risk of contracting HIV.&lt;/p&gt;
&lt;p&gt;Researchers reasoned that a converse effect might also be true  --  treating HSV-2 in HIV-negative people might reduce their risk of infection.&lt;/p&gt;
&lt;p&gt;The reasoning was bolstered by clinical trials showing that treating HSV-2 in HIV-positive people lowered their viral load.&lt;/p&gt;
&lt;p&gt;In the current study, that effect also occurred. HIV-positive volunteers treated with acyclovir saw, on average, a reduction in plasma concentration of HIV by 0.25 log&lt;sub&gt;10&lt;/sub&gt; copies per milliliter compared with members of the placebo group. The difference was significant at &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001.&lt;/p&gt;
&lt;p&gt;But transmission among the couples was not affected, implying that a greater reduction in viral load is needed, the researchers said.&lt;/p&gt;
&lt;p&gt;The study, randomized and placebo-controlled, included 3,408 couples in Africa in which only one of the partners had HIV (but was not taking antiretroviral therapy) and also had an HSV-2 infection.&lt;/p&gt;
&lt;p&gt;The outcome was first reported at the Cape Town meeting of the International AIDS Society last year (See &lt;a href=&quot;http://www.medpagetoday.com/MeetingCoverage/IAS/15242&quot; mce_href=&quot;http://www.medpagetoday.com/MeetingCoverage/IAS/15242&quot; target=&quot;_blank&quot;&gt;IAS: Acyclovir Flops in Preventing HIV Transmission&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;The primary outcome was transmission between partners, verified by genetic sequencing of the virus.&lt;/p&gt;
&lt;p&gt;Transmission between partners was verified in 84 of the 132 recorded cases of transmission, the researchers said, and they were evenly divided  --  41 among those getting the drug and 43 in the placebo group.&lt;/p&gt;
&lt;p&gt;On the other hand, the use of the drug reduced the occurrence of herpes lesions by 73%, which was significant at &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001.&lt;/p&gt;
&lt;p&gt;The reduction of herpes lesions suggests that the drug was being used, the researchers said, and therefore that the lack of efficacy against HIV was not a result of nonadherence to acyclovir.&lt;/p&gt;
&lt;p&gt;Overall, the rate of HIV transmission in the study was 2.7 cases per 100 person-years, markedly lower than earlier observations. The researchers attributed that to such interventions as monthly counseling on risk reduction and free condoms.&lt;/p&gt;

                     href="http://www.medpagetoday.com/HIVAIDS/HIVAIDS/tb/18037?impressionId=1265790468843"
                     
      &lt;p&gt;Home-based care can improve some aspects of HIV treatment, according to a systematic review of reported studies.&lt;/p&gt;
&lt;p&gt;But the evidence is slim, and no studies looked at how home-based care affects AIDS progression or death, according to Taryn Young, MBChB, of the Medical Research Council of South Africa, and Karishma Busgeeth of the Council for Scientific and Industrial Research in Pretoria, South Africa.&lt;/p&gt;
&lt;p&gt;In addition, few of the studies evaluated home-based care in developing countries, where it is being considered to alleviate pressure on hospitals, the researchers noted in a &lt;em&gt;Cochrane Systematic Review&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Home-based care is aimed at improving quality of life and reducing the need for hospital care, &quot;especially where public health services are overburdened,&quot; the researchers wrote in the review.&lt;/p&gt;
&lt;p&gt;But there has been no systematic evaluation of home-based care in the setting of HIV/AIDS, they said.&lt;/p&gt;
&lt;p&gt;To help fill the gap, they found 13 published reports, referring to 11 randomized clinical trials, as well as two such trials currently under way.&lt;/p&gt;
&lt;p&gt;Of the 11 studies with published reports, 10 randomized individuals and one (in Uganda, the only one conducted in Africa) randomized households.&lt;/p&gt;
&lt;p&gt;The studies looked at a range of interventions: &lt;ul&gt; &lt;li&gt;Three studies evaluated home-based intensive nursing versus standard care for effects on patient knowledge of HIV and related medication, adherence, viral load, and CD4 counts.&lt;/li&gt; &lt;li&gt;Two studies compared a transprofessional team versus an independent primary care nurse. One looked at quality of life and survival and the other at the time patients spent in the program, as well as cost.&lt;/li&gt; &lt;li&gt;Two studies compared the effect of computer-based education versus brochures, nothing, or standard medical care on such outcomes as perceived social isolation, decision-making confidence, health status, quality of life, risk behaviors, and health service utilization.&lt;/li&gt; &lt;li&gt;Two studies looked at exercise.&lt;/li&gt; &lt;li&gt;One study looked at two months of home total parenteral nutrition versus dietary counseling.&lt;/li&gt; &lt;li&gt;One study of diarrhea compared home-based water chlorination, safe storage, and education with education alone.&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The researchers reported that intensive home-based nursing significantly improved self-reported knowledge of HIV and medications, self-reported adherence, and differences in pharmacy drug refills.&lt;/p&gt;
&lt;p&gt;Another study, which looked at the proportion of participants with greater than 90% adherence, found statistically significant differences over time with home-based nursing. But that study found no significant change in CD4 counts and viral loads.&lt;/p&gt;
&lt;p&gt;The third such study found significant differences in HIV stigma, worry, and physical functioning but no differences in depressive symptoms, mood, general health, and overall functioning.&lt;/p&gt;
&lt;p&gt;The studies comparing comprehensive case management by transprofessional teams compared to usual care by primary care nurses showed no effect.&lt;/p&gt;
&lt;p&gt;The study comparing home total parenteral nutrition and dietary counseling found no significant impact on overall survival and rate of readmission to hospital.&lt;/p&gt;
&lt;p&gt;The two computer-based studies found no effect on health status and decision-making confidence and skill, but did find a reduction in social isolation after controlling for depression.&lt;/p&gt;
&lt;p&gt;The two trials evaluating home exercise programs found conflicting results.&lt;/p&gt;
&lt;p&gt;And the home-based safe water systems reduced diarrhea frequency and severity among persons with HIV in Africa, the researchers reported.&lt;/p&gt;
&lt;p&gt;In general, the researchers concluded that there were few studies; study populations tended to be small; and the studies did not address the effect of home-based care on important medical endpoints, such as mortality.&lt;/p&gt;
&lt;p&gt;&quot;Further large studies should therefore focus on evaluating these significant endpoints, on feasible interventions for developing countries, and on how home-based care fits into the current treatment context,&quot; they concluded.&lt;/p&gt;
