      Preterm birth complicated by chorioamnionitis may modestly increase a child&apos;s risk of later asthma, researchers found.&lt;br&gt;
&lt;br&gt;Children born preterm after a pregnancy complicated by the bacterial infection of placenta and amniotic fluid (chorioamnionitis) were significantly more likely to develop asthma by age eight than preemies without such exposure, according to Darios Getahun, MD, MPH, of Kaiser Permanente Department of Research and Evaluation in Pasadena.&lt;br&gt;
&lt;br&gt;Asthma diagnosis was nearly threefold more common among chorioamnionitis-exposed children who had been born preterm than those carried to term, they wrote in the February &lt;em&gt;Archives of Pediatrics &amp;amp; Adolescent Medicine&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;Premature birth may not give an infant&apos;s lungs a chance to fully develop, leading to early infection and inflammation that elevate risk of chronic lung disease, such as asthma.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;However, in utero exposures could be an important contributor as well, Getahun explained in an interview.&lt;/p&gt;
&lt;p&gt;Chorioamnionitis is thought to be associated with more than half of all preterm births.&lt;/p&gt;
&lt;p&gt;Fetal lungs stay in contact with the amniotic fluid which, when infected, may expose the developing lung to microorganisms, toxic substances, and inflammatory mediators, the researchers wrote.&lt;/p&gt;
&lt;p&gt;Animal model evidence suggests the condition may lead to scarring and fibrosis in the lung and damage to other fetal organs &quot;during a very critical time at preterm gestation,&quot; Getahun told &lt;em&gt;MedPage Today&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;So, his group retrospectively studied Kaiser&apos;s matched perinatal records on 510,216 singleton children born at the managed care group&apos;s hospitals in Southern California between 1991 and 2007.&lt;/p&gt;
&lt;p&gt;Physician-diagnosed asthma incidence by age 8 years, as expected, was significantly higher overall for preemies born at 23 to 36 weeks&apos; gestation than for those carried full-term (60.2 versus 40.0 per 1,000 person-years).&lt;/p&gt;
&lt;p&gt;But chorioamnionitis diagnosed during pregnancy substantially boosted this risk.&lt;/p&gt;
&lt;p&gt;Incidence of asthma rose to 100.7 per 1,000 person-years in exposed children born preterm, versus 39.6 per 1,000 among exposed, full-term children (IR 2.9, 95% CI 2.6 to 3.3).&lt;/p&gt;
&lt;p&gt;This association between chorioamnionitis and asthma in preemies persisted (HR 1.68, 95% CI 1.52 to 1.87) after adjustment for important confounding variables, including maternal age, race or ethnicity, smoking during pregnancy, prenatal care, and maternal asthma.&lt;/p&gt;
&lt;p&gt;Although the asthma risk appeared to rise with greater prematurity in exposed children, the elevated risk associated with chorioamnionitis exposure in utero was seen in every category of prematurity: &lt;ul&gt; &lt;li&gt; 1.23 times higher risk in children born at 23 to 28 weeks (95% CI 1.02 to 1.49)&lt;/li&gt; &lt;li&gt; 1.51 times higher risk in children born at 28 to 33 weeks (95% CI 1.26 to 1.80)&lt;/li&gt; &lt;li&gt; 1.20 times higher risk in children born at 34 to 36 weeks (95% CI 1.03 to 1.47)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Additional adjustment for bronchopulmonary dysplasia  --  &quot;one of the mechanisms through which preterm birth is presumably associated with respiratory problems in early childhood&quot;  --  had little impact on the findings.&lt;/p&gt;
&lt;p&gt;Thus, the bacterial infection appeared to be an independent risk factor for asthma in prematurely born children, the researchers concluded.&lt;/p&gt;
&lt;p&gt;The risks were particularly high for children born to African-American women who developed chorioamnionitis, suggesting this may be an at-risk group to single out for attention clinically, they suggested.&lt;/p&gt;
&lt;p&gt;Getahun cautioned, though, that his group&apos;s study could not prove causality. The researchers also noted that the study was limited by lack of data on parental atopy and smoking.&lt;/p&gt;

      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;

      &lt;p&gt;Doctor&apos;s Orders&lt;em&gt; is a feature in the collaboration between &lt;/em&gt;MedPage Today &lt;em&gt;and&lt;/em&gt; ABC News&lt;em&gt;. In this monthly segment we explore medical issues of interest to physicians and their patients alike. This month, we look at addiction and addictive behaviors, and what neuroimaging studies have revealed about why it&apos;s so hard to break bad habits. &lt;/em&gt;&lt;/p&gt;&lt;hr&gt;

&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;By the end of January, many New Year&apos;s resolutions have been tossed out with the leftover holiday cookies. That&apos;s because change is hard  --  and neuroscientists are learning why.&lt;br&gt;
&lt;br&gt;Advances in neuroimaging have enabled researchers to peer inside the brains of addicts and patients with addictive behaviors. They can see in real-time what gets patients hooked: how the brain&apos;s reward system  --  based largely on the neurotransmitter dopamine  --  thirsts for more, while inhibitory control centers experience a system failure.&lt;br&gt;
&lt;br&gt;The pattern is similar across all kinds of behaviors  --  from cocaine and tobacco addiction to overeating. That&apos;s why changing your mind may be the first step toward breaking a habit, but altering the brain&apos;s neural machinery is the real challenge.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Hijacked Pathways&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Drug-taking and other addictive behaviors &quot;hijack&quot; the brain&apos;s reward system, says Petros Levounis, MD, director of the Addiction Institute of New York at St. Luke&apos;s and Roosevelt Hospitals in Manhattan.&lt;/p&gt;
&lt;p&gt;In normal patients, dopamine plays a major role in motivation and reward, surging before and during a pleasurable activity  --  say, eating or sex  --  to make patients want to repeat a behavior that&apos;s crucial to the survival of the species.&lt;/p&gt;
&lt;p&gt;Dopaminergic pathways connect the limbic system, responsible for emotion, with the hippocampus, etching rewarding behaviors into the brain by creating strong, salient memories.&lt;/p&gt;
&lt;p&gt;The problem arises when the memory and the craving to recapture it takes over a person&apos;s life.&lt;/p&gt;
&lt;p&gt;&quot;Imagine what a strong hold these hijacked reward pathways take on our brains and our whole existence when they&apos;re so closely connected, geographically and anatomically speaking, with our memories and our emotions,&quot; Levounis says.&lt;/p&gt;
&lt;p&gt;As the dopamine surge repeats and repeats, it gains speed, but the brakes begin to fail: Normal function in the brain&apos;s frontal lobes, responsible for inhibitory control and executive functioning (read: willpower), tends to decrease in addicts.&lt;/p&gt;
&lt;p&gt;&quot;Ultimately,&quot; Levounis says, &quot;the war on drugs is a war between the hijacked reward pathways that push the person to want to use, and the frontal lobes, which try to keep the beast at bay. That is the essence of addiction.&quot;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Similar Patterns&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;These neural pathways have been well studied in the brains of hardcore addicts. Now, researchers say they see similar pathways involved in other bad behaviors.&lt;/p&gt;
&lt;p&gt;Gene-Jack Wang, MD, of Brookhaven National Laboratory on New York&apos;s Long Island, has conducted several brain imaging studies of obese patients using PET-CT scans.&lt;/p&gt;
&lt;p&gt;The scans have revealed similarities in brain activity  --  or a lack thereof  --  between patients addicted to cocaine or alcohol, and those &quot;addicted&quot; to eating. Normally, the PET scan lights up when a contrast of radioactive glucose is metabolized, revealing an area of red activity in the center of the brain.&lt;/p&gt;
&lt;p&gt;But in both drug-addicted and obese patients, the scans show very little red activity, because there aren&apos;t enough receptors to which the radioactive glucose can bind. Wang says the decreased availability of dopamine receptors is the brain&apos;s way of coping with a constant dopamine overload.&lt;/p&gt;
&lt;p&gt;&quot;If a person constantly has an excess of dopamine, the brain will down-regulate,&quot; Wang says, explaining the principle commonly referred to as tolerance. &quot;Once the system is down-regulated, we have to do more in order to get the same amount of feeling in our normal state.&quot;&lt;/p&gt;
&lt;p&gt;Thus, obese patients &quot;will want to eat more in order to compensate for their down-regulated system.&quot;&lt;/p&gt;
&lt;p&gt;In other experiments, Wang and his colleagues have also found that a higher body mass index (BMI) correlated with lower prefrontal cortex function  --  the area associated with inhibitory control.&lt;/p&gt;
&lt;p&gt;&quot;If they&apos;re obese,&quot; Wang said, &quot;they have a problem controlling their eating behaviors.&quot;&lt;/p&gt;
&lt;p&gt;Those studies also revealed that a higher BMI was linked to a decrease in memory and executive functioning.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Out of Control&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Ed Susman was 293 pounds when he decided to join a clinical trial for an investigational weight-loss drug and chronicle his year-long experience for &lt;em&gt;MedPage Today&lt;/em&gt;. (See &lt;a href=&quot;http://www.medpagetoday.com/PrimaryCare/Diabetes/8125&quot; mce_href=&quot;http://www.medpagetoday.com/PrimaryCare/Diabetes/8125&quot; target=&quot;_blank&quot;&gt;Journalist Participant to Present Insider View of Weight-Loss Trial&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;Eating, to him, was a &quot;compulsion&quot;  --  as was biting his nails, a habit he picked up at age 4.&lt;/p&gt;
&lt;p&gt;Over the course of the trial, not only did Susman lose 52 pounds, he also stopped his nail-biting.&lt;/p&gt;
&lt;p&gt;He doesn&apos;t yet know if he was in the drug arm of the trial, but he strongly suspects he wasn&apos;t experiencing a placebo effect.&lt;/p&gt;
&lt;p&gt;&quot;I believe I was on the drug because it controlled a compulsion that I had had for 50 years,&quot; Susman says of the nail-biting. &quot;This stopped it cold.&quot;&lt;/p&gt;
&lt;p&gt;Unfortunately, he says, the same didn&apos;t happen with his eating habits, but he&apos;s gained back only 10 of those 52 pounds in the year since his participation in the trial ended.&lt;/p&gt;
&lt;p&gt;The still-investigational drug is lorcaserin  --  a combination of benzazepine and hydrochloride, two neurological agents. Susman says it is &quot;supposed to improve your willpower, your ability to overcome compulsions.&quot;&lt;/p&gt;
&lt;p&gt;Lorcaserin is a selective 5-HT&lt;sub&gt;2C&lt;/sub&gt; receptor agonist, working through the serotonin system, which regulates appetite, mood, and motor behavior.&lt;/p&gt;
&lt;p&gt;Two other investigational obesity drugs target the dopamine reward system  --  Contrave, which is a combination of bupropion and naltrexone, and Qnexa, which combines phentermine and topiramate.&lt;/p&gt;
&lt;p&gt;&quot;Some medications that have used similar dopamine modulation, until now, have failed,&quot; Wang said. &quot;These two companies are using the command of the modulation of the dopamine system with other neurological systems, such as the opiate or norepinephrine system. According to the trials, they&apos;ve been very effective.&quot;&lt;/p&gt;
&lt;p&gt;Wang called the new medications &quot;a bright light for the treatment of obesity.&quot;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Kicking the Habit&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Basically, the idea of medications that act on the dopamine system is &quot;to cool down those reward pathways,&quot; Levounis says. There are two strategies for doing so: an agonist strategy, or an antagonist strategy.&lt;/p&gt;
&lt;p&gt;The agonist strategy is &quot;feeding the beast, providing activity in the cell so that the cravings go down,&quot; Levounis said. Classic examples are nicotine patches, or methadone for opioid dependence.&lt;/p&gt;
&lt;p&gt;On the other hand, the antagonist strategy is to block the receptors. Naltrexone, for example, will block opioid receptors so that the drug addict won&apos;t feel anything if he or she attempts to get high.&lt;/p&gt;
&lt;p&gt;&quot;After a while, you say, &apos;This is not worth my time, my money, my trouble,&apos; so you stop using,&quot; Levounis explains.&lt;/p&gt;
&lt;p&gt;These have been the two main strategies in addiction pharmacotherapy, but there&apos;s now a &quot;third avenue&quot;  --  the partial agonist approach.&lt;/p&gt;
&lt;p&gt;The partial agonist is one molecule that blocks most receptors while still providing just a little bit of an &quot;oomph&quot; to calm cravings. That&apos;s how varenicline (Chantix) helps smokers quit, and how buprenorphine gets junkies off heroin or other opioids.&lt;/p&gt;
&lt;p&gt;But what about inhibitory control? What if medications could ramp up will power?&lt;/p&gt;
&lt;p&gt;&quot;It&apos;s an area of active research,&quot; Levounis says. &quot;There are some medications proposed, but nothing to write home about.&quot;&lt;/p&gt;
&lt;p&gt;He said treatment is typically twofold. For addicts, psychiatrists will try to &quot;cool down&quot; the reward pathways, often with medication. Then, they target the diminished frontal lobes.&lt;/p&gt;
&lt;p&gt;&quot;We try to beef up the frontal lobes as much as we can, and we do that with psychotherapy,&quot; Levounis said.&lt;/p&gt;
&lt;p&gt;Researchers agree that psychotherapy is key to regaining self-control, and it&apos;s the predominant treatment used in patients with addictive behaviors.&lt;/p&gt;
&lt;p&gt;Mark Smaller, PhD, a psychoanalyst in private practice in Chicago, said psychotherapy often reveals an underlying cause for an addiction or compulsive behavior. Usually, it&apos;s anxiety or depression.&lt;/p&gt;
&lt;p&gt;Acknowledging those problems may help change behaviors. Once they&apos;re realized, a patient can start working against them, with the help of the brain&apos;s own neuroplasticity. Essentially, neurons can disconnect and reconnect, or loosen their connections and tighten them, which often manifests in noticeable change.&lt;/p&gt;
&lt;p&gt;&quot;[Psychological] insights can actually begin to change brain chemistry and diffuse compulsions,&quot; he said. &quot;If you address those issues, you can have a positive impact on your life that can change the chemistry of your brain.&quot;&lt;/p&gt;
&lt;p&gt;Smaller said it &quot;creates a new psychological  --  if not neurological  --  structure that can help regulate behavior.&quot;&lt;/p&gt;
&lt;p&gt;Although research on neuroplasticity is relatively young, the concept of &quot;rewiring&quot; the brain is not new.&lt;/p&gt;
&lt;p&gt;In fact, too often, the electrician metaphor has been employed as an excuse for indulging, an explanation for a New Year&apos;s resolution deferred: &quot;I can&apos;t stop eating chocolate, I&apos;m just not wired that way.&quot;&lt;/p&gt;

                     score="0.002"
                     href="http://www.medpagetoday.com/OBGYN/Pregnancy/tb/18162?impressionId=1265755755099"
                     
      &lt;p&gt;After a decade of decline, the rate of teenage pregnancies increased by 3% in 2006 as 750,000 women younger than 20 became pregnant, according to a report released by the Guttmacher Institute.&lt;/p&gt;
&lt;p&gt;And as pregnancies increased, so did births  --  41.9 births per 1,000 U.S. teenage girls, which was 4% higher than in 2005  --  and abortions, which increased by 1% from 2005 to 2006.&lt;/p&gt;
&lt;p&gt;In a prepared statement, Planned Parenthood blamed abstinence-only sex education programs for the uptick.&lt;/p&gt;
&lt;p&gt;&quot;It is a tragedy that after a decade of progress in reducing the rate of teenage pregnancy we are witnessing a substantial increase in the number of teens who are getting pregnant,&quot; Planned Parenthood said.&lt;/p&gt;
&lt;p&gt;In a statement released last May in conjunction with the &quot;National Day to Prevent Teen Pregnancy&quot; the American College of Obstetricians and Gynecologists (ACOG), agreed that comprehensive sex education was likely to be more effective than abstinence-only programs.&lt;/p&gt;
&lt;p&gt;&quot;Abstinence works for some teens, but the idea that most teens will wait to have sex indefinitely is rigid and impractical,&quot; said Richard S. Guido, MD, chair of the ACOG&apos;s Committee on Adolescent Health Care.&lt;/p&gt;
&lt;p&gt;But the Guttmacher report suggested that the reasons for increase may be more complex, including &quot;shifts in the racial and ethnic composition of the population, increases in poverty, the growth of abstinence-only sex education programs at the expense of comprehensive programs, and changes in public perception and attitudes toward both teenage and unintended pregnancy.&quot;&lt;/p&gt;
&lt;p&gt;Among black teenagers the pregnancy rate was 126.3 per 1,000 versus 44 per 1,000 non-Hispanic white teenagers.&lt;/p&gt;
&lt;p&gt;A breakdown by state revealed that New Mexico had the highest teenage pregnancy rate, followed by Nevada, Arizona, Texas, and Mississippi.&lt;/p&gt;
&lt;p&gt;Conversely, the lowest teenage pregnancy rate was in New Hampshire  --  33 pregnancies per 1,000  --  followed by Vermont, Maine, Minnesota, and North Dakota.&lt;/p&gt;
&lt;p&gt;Texas had the highest rate of births to teenage mothers  --  62 per 1,000  --  and New York had the highest rate of abortions among teenagers, 41 per 1,000.&lt;/p&gt;
&lt;p&gt;The report was based on data from the National Center for Health Statistics of the U.S. Department of Health and Human Services (number of births), the Guttmacher Institute (total number of abortions), the U.S. Centers for Disease Control and Prevention (age and race/ethnicity distribution of women obtaining abortions), and the Population Estimates Program of the U.S. Bureau of the Census in collaboration with NCHS (population estimates).&lt;/p&gt;
&lt;p&gt;Among other findings in the report: &lt;ul&gt; &lt;li&gt;The pregnancy rate was 71.5 pregnancies per 1,000 girls ages 15-19 and pregnancies occurred among 7% of females in this age group.&lt;/li&gt; &lt;li&gt;Although teenage abortions increased by 1% from 2005 to 2006, the overall teenage abortion rate declined by about a third over the two decades from 1986 to 2006.&lt;/li&gt; &lt;li&gt;The increase in teen pregnancies and births to teenage mothers was observed across all racial and ethnic groups.&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The authors said that additional research was needed to determine if the disparities in rates by both race and region carry over to adult women.&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;
