The study has implications for understanding rare but life-threatening infections during pregnancy. More than a half-million women have taken the two-drug combination safely since its FDA approval in 2000.
A recent study highlights the need for better treatments for malaria in pregnancy, where the use of new medicines is often restricted due to limited clinical data. The authors argue that this 'catch-22' situation can lead to inferior drugs being prescribed, putting pregnant women's lives at risk.

Psychosocial support during key moments improved handling of the infection, while male partner involvement led to a significant increase in women agreeing to testing.
A Norwegian study found that mothers born in India, Sri Lanka, and Africa have a higher prevalence of hyperemesis gravidarum due to genetic factors. Mothers aged 20-24 years old and those with multiple fetuses also showed increased risk.
A study of 740 pregnant women in the UK found a clear link between mother's diet and infant sex, with higher energy intake around conception associated with an increased likelihood of having a son. Women who consumed more calories, especially from breakfast cereals, were also more likely to have sons.

A new University of Washington study found that despite public health campaigns, many women continue to use substances like tobacco, marijuana, and alcohol during pregnancy, while their partners' use remains stable. Men's patterns of substance use are bleaker, with men typically not targeted by these campaigns.
A medical team from the University of Leicester has developed a predictor for pregnant women who may have miscarriages, using levels of anandamide in whole blood. The study found that women with higher levels of anandamide were more likely to miscarry, while those with lower levels were more likely to have a live birth.
Research on over 18,000 UK babies found that mothers who quit smoking during pregnancy had the most easy-going infants. The study suggests that quitting smoking may boost a child's temperament and reduce behavioral problems. Heavy smokers had more difficult children with lower scores for positive mood.
A research team at Université Laval has identified genetic markers that allow the selection of eggs with the best chance of leading to successful pregnancy after in vitro fertilization (IVF). This method increases the success rate of single embryo transfer and diminishes the risk of multiple pregnancies.
Obese women should not be encouraged to gain at least 15 pounds during pregnancy, according to Saint Louis University obstetrician Raul Artal. Engaging in physical activity and proper diet can help prevent health issues like hypertension and diabetes.
A $30 million grant will fund research to improve malaria control and treatment in pregnancy across Africa, Asia, and Latin America. The initiative aims to reduce maternal anaemia and low birth weight, potentially saving the lives of up to 100,000 children every year.
Research found that women consuming high amounts of meat and low amounts of fish have lower levels of omega-3 fatty acids, which are crucial for brain and eye function. This may lead to developmental delays in infants, emphasizing the need for dietary recommendations that promote optimal health for mothers and babies.
A study suggests that expectant women treated with imatinib for chronic myeloid leukemia (CML) may be at moderate risk of developing fetal abnormalities. The majority of pregnancies resulted in normal live infants, but some were born with congenital abnormalities, including exomphalos, renal agenesis, and hemivertebrae.
African American adolescent mothers with depression are more likely to have a subsequent pregnancy within two years of giving birth. Depressive symptoms were associated with a 44% increase in risk of subsequent pregnancy, highlighting the importance of treating maternal depression.
Researchers found that tobacco use and secondhand smoke exposure among pregnant women pose significant threats to maternal and child health. In some countries, rates of tobacco-related exposures are already high enough to warrant substantial concern.
Research suggests that about one in four women with HIV expect pregnancy and motherhood, with younger women more likely to make this choice. The study highlights the need for clinicians to discuss pregnancy options with HIV-positive women of childbearing age.
A large-scale study published in the American Journal of Obstetrics & Gynecology found a strong link between physical abuse during pregnancy and premature births. Researchers surveyed 2660 Caucasian women and discovered that 24% of mothers of preterm newborns had experienced physical abuse, compared to 8% of those with term births.
A University of Houston professor found a new side effect of lead exposure: obesity in male mice born to mothers exposed to varying levels of lead. The study suggests that the link may be related to testosterone or other hormones, and highlights the need for lower acceptable lead exposure rates for pregnant women and children.
Researchers have discovered a link between viral infection, particularly from the herpes group, and pregnancy-induced hypertensive disease and pre-term birth. The study found viral nucleic acid in heel-prick blood samples of 1326 newborn babies, including over 400 with cerebral palsy.

A study of over 1.38 million Danish births found a significant association between exposure to severe stressful events during the first trimester and an increased risk of schizophrenia in children. Chemicals released by the mother's brain in response to stress may affect fetal brain development, particularly in early pregnancy.
A study by Yale University researchers has identified a gene, ENPP1, linked to preterm birth and low birth weight in Hispanic women. The study found that this variant of the gene may be associated with deranged energy metabolism, a possible explanation for preterm births.
A recent study by Yale University researchers found that IVF twin pregnancies have a higher prevalence of congenital heart disease (CHD) compared to singletons. The study, which examined almost 2,000 patients, revealed a three-fold increase in CHD among IVF twins.
A new study published in Social Science Quarterly reveals that religious women are less likely to obtain abortions compared to secular women. This is because religious women tend to lead more sexually conservative lifestyles, which reduces their likelihood of becoming pregnant before marriage and seeking an abortion.
A Kaiser Permanente study found that high doses of caffeine daily during pregnancy increase the risk of miscarriage, particularly among women consuming coffee, tea, and hot chocolate. Women who consumed over 200mg of caffeine per day had twice the miscarriage risk compared to those with no caffeine intake.
The pharmaceutical industry is failing pregnant women due to a lack of drug development for maternal health, with only 17 drugs in active development. This 'drug drought' is attributed to the high litigation costs associated with testing and developing drugs during pregnancy.
The Lancet study highlights the urgent need to address undernutrition in 20 countries accounting for 80% of the world's undernourished children. Interventions with proven effectiveness should be implemented at scale, and programme efforts should focus on the critical window of pregnancy to 24 months of age.
