Life-threatening complications during pregnancy: greater long-term risk of death

2021-01-26
(Press-News.org) A research team from the CHUM Research Centre (CRCHUM) has shown that women who have had serious complications during pregnancy are twice as likely to die up to three decades later.

Serious conditions such as stroke, cardiac complications, acute kidney failure and pre-eclampsia affect just under 5 % of women during pregnancy and childbirth.

In a study published in Obstetrics & Gynecology, CRCHUM researcher Dr. Nathalie Auger and postdoctoral fellow Ugochinyere Vivian Ukah examined the long-term mortality risks of women with these types of pregnancy complications by analyzing more than 1.2 million records of women who gave birth in Quebec between 1989 and 2016.

Their findings? Compared to women who had no serious pregnancy complications, women in the study were twice as likely to die after childbirth, either in the postpartum period (42 days and less) or afterwards. Although there was a decline over time, the greater risk of death was still felt several years after delivery, with death occurring an average of 8.3 years earlier for women with severe pregnancy complications compared with no complications.

The research team was also able to identify the main causes of mortality after 42 days: serious cardiac complications during pregnancy (7 times more likely to die), acute renal failure (4 times more likely), and strokes (4 times more likely).

From a clinical point of view, closer follow-up and preventive interventions to reduce the risk of premature mortality could be justified for women with severe pregnancy complications.

Partners in crime: genetic collaborator may influence severity of the rare disease, NGLY1
2021-01-26
In 2012, four-year-old Bertrand Might became the first-ever patient diagnosed with a rare genetic disorder called N-glycanase (NGLY1) deficiency. The discovery of this condition and Bertrand's diagnosis allowed doctors to look for other children with the same genetic defect. Since then, more than 60 additional patients have been found. The disease affects every system of the body and is characterized by low muscle tone, seizures, developmental delays, and an inability to produce tears. Sadly, Bertrand passed away in October at the age of 12. Although his life was cut short, his legacy will benefit children around the world. Through ...

UC study: The dangers of drugged driving are outpacing drunk driving

UC study: The dangers of drugged driving are outpacing drunk driving
2021-01-26
A recent study of drugged driving, by a team of University of Cincinnati researchers, shows that a sizable percentage of individuals reported the use of marijuana and other illicit drugs while operating behind the wheel. "We need to focus our efforts on drugged driving, in addition to drunk driving, because drugged driving causes such a high level of fatalities, says Andrew Yockey, a doctoral student in UC's College of Education, Criminal Justice and Human Services and researcher at the UC Center for Prevention Science. Yockey is lead author on the study ...

Hybrid closed-loop insulin therapy improves glycemic control

Hybrid closed-loop insulin therapy improves glycemic control
2021-01-26
New Rochelle, NY, January 26, 2021--Hybrid closed-loop insulin therapy improved glycemic control in adolescents and young adults with type 1 diabetes. These outcomes, derived from the International Diabetes Closed-Loop (iDCL) Trial, are reported in the peer-reviewed journal Diabetes Technology & Therapeutics (DTT). Click here to read the article now. Adolescents and young adults with a mean age of 17 years were randomly assigned to a closed-loop control (CLC) insulin delivery system or a sensor augmented pump (SAP) with a continuous glucose monitoring system over a 6-month period. The Time in Range increased by 13% for the CLC group, compared to a decrease of 1% with SAP, for a group ...

Satellite data reveals bonds between emissions, pollution and economy

Satellite data reveals bonds between emissions, pollution and economy
2021-01-26
Burning fossil fuels has long powered world economies while contributing to air pollution and the buildup of greenhouse gases. A new analysis of nearly two decades of satellite data shows that economic development, fossil-fuel combustion and air quality are closely linked on the continental and national scales, but can be decoupled at the national level, according to Penn State scientists. "We know air pollution and economic development are linked, but we want to know how tightly and whether our actions can change this," said Ruixue Lei, a post-doctoral researcher in the Department of Meteorology and Atmospheric Science. "We found they are not inherently bonded and can be decoupled under favorable policies." While previous research has explored the connections between air ...

Researchers simplify the study of gene-environment interactions

2021-01-26
Researchers at Weill Cornell Medicine and Cornell University's Ithaca campus have developed a new computational method for studying genetic and environmental interactions and how they influence disease risk. The research, published Jan. 7 in The American Journal of Human Genetics, makes the process of finding these interactions much less difficult and demonstrates their importance in determining body mass index and diabetes risk. "Our study demonstrates that your genes matter and the environment matters and that the interaction of the two can increase risk for disease," said co-senior author, Dr. Olivier ...

Ocean toxin a heartbreaking threat for sea otters

Ocean toxin a heartbreaking threat for sea otters
2021-01-26
Heart disease is a killer threat for southern sea otters feasting on domoic acid in their food web, according to a study led by the University of California, Davis. The study, published in the journal Harmful Algae, examined the relationship between long-term exposure to domoic acid and fatal heart disease in southern sea otters, a threatened marine mammal. "Sea otters are an amazing indicator of what's happening in the coastal environment, not just to other marine animals, but to us, too, especially on the issue of domoic acid," said Christine K. Johnson, director of the EpiCenter ...

Southern Africa's most endangered shark just extended its range by 2,000 kilometers

2021-01-26
MAPUTO, Mozambique (January 26, 2021) - A team of marine scientists led by the Wildlife Conservation Society (WCS) has confirmed that southern Africa's most threatened endemic shark - the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) - has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles). Publishing their findings in the journal Marine Biodiversity, the team said that the discovery was based on several records of the shark including underwater video surveys collected in 2019, recent photos of shore-based sport anglers' catches, and the identification of a specimen collected in 1967. The ...
