AI Article Synopsis
- The study analyzed trends in cardiomyopathy during pregnancy using hospital discharge data from Florida between 1998 and 2007, involving over 1.7 million births.
- Over the decade, the prevalence of cardiomyopathy in pregnant women rose significantly from 8.5 to 32.7 cases per 100,000 births, marking a 300% increase.
- Infants of mothers with cardiomyopathy were at greater risk for various complications, such as low birth weight and preterm birth, indicating a pressing need for better understanding and management of risk factors in pregnant women with this condition.
Article Abstract
Objective: To examine temporal trends of cardiomyopathy in pregnancy and its association with feto-infant morbidity outcomes.
Design And Methods: We performed a population-based retrospective cohort analysis utilizing the Florida hospital discharge data linked to vital statistics for 1998 to 2007 (N = 1 738 860). Prevalence rates and trend statistics of cardiomyopathy were computed. Conditional logistic regression models were used to generate adjusted odds ratios (AOR) and 95% confidence intervals (CI).
Results: The annual prevalence of cardiomyopathy in pregnancy increased from 8.5/100 000 births to 32.7/100 000 (p for trend <0.0001), representing an absolute increase of 24% and a relative increase of 300% over the decade. Infants born to women with cardiomyopathy were at higher risk for feto-infant morbidities, including low birth weight (AOR = 3.49, 95% CI: 2.97-4.11), very low birth weight (AOR = 4.43, 95% CI: 2.98-6.60), preterm birth (AOR = 3.33, 95% CI: 2.88-3.85), very preterm birth (AOR = 5.22, 95% CI: 3.92-6.97) and small for gestational age (AOR = 1.57, 95% CI: 1.26-1.96).
Conclusion: The observed increasing prevalence of cardiomyopathy during pregnancy over the decade is of concern, as it is related to elevated risk for feto-infant morbidities. There is a need to delineate risk factors for this condition and to formulate appropriate preconception counseling for women with elevated risk for this diagnosis.

Peripartum cardiomyopathy (PPCM) is a rare, but serious condition, with a non-negligible risk of adverse events. Several risk factors for PPCM have been individuated over the years, including Afro-American ethnicity, preeclampsia, advanced maternal age, genetic predisposition, multiparity, twin pregnancy, obesity, smoking and diabetes. However, PPCM pathophysiology is still poorly understood, thus making it challenging to develop disease specific therapies.

Streptococcus pneumoniae is a leading cause of pneumonia, meningitis, and invasive pneumococcal disease among adults in the United States, with higher rates of disease occurring among individuals with chronic medical and immunocompromising conditions. Pregnant individuals, especially those with co-morbid conditions, are also at increased risk of infection due to S. pneumoniae due to physiologic and immunologic changes in pregnancy.

Background: Carbon monoxide (CO) poisoning is a serious yet frequently overlooked condition with diverse and nonspecific clinical presentations. The analysis of Lithuanian statistics reveals fluctuations in patient admissions and consultations through the poisoning center over a four-year period, with notable variations in fatality rates. Despite these trends, CO poisoning remains a significant public health concern due to its potential for severe long-term sequelae or death.

Peripartum cardiomyopathy is an idiopathic and nonischemic systolic dysfunction with onset toward the end of pregnancy and up to 5 months postpartum. Its clinical phenotype overlaps with pregnancy-associated cardiomyopathy rendering both a continuum of the same disease. Incidence varies geographically and is highest in areas where risk factors are prevalent.
