Cardiac evaluation in pregnant patients with dyspnea and palpitations.

BACKGROUND: Symptoms of underlying cardiac disease in pregnancy can often be mistaken for common complaints because of normal physiological changes in pregnancy. Echocardiographic evaluation of patients with symptoms of palpitations and dyspnea can detect structural changes and identify high-risk features. OBJECTIVE: This study aimed to examine transthoracic echocardiograms of perinatal individuals completed for palpitations or dyspnea to determine the frequency of identifying structural changes. STUDY DESIGN: This was a retrospective cohort study of all perinatal individuals with a transthoracic echocardiogram at a single academic center between October 1, 2017, and May 1, 2022. The indication for the echocardiogram, demographics, and clinical characteristics were recorded. Transthoracic echocardiograms with any abnormal findings noted in the transthoracic echocardiogram report were reviewed and categorized into findings of congenital heart disease, valvular disease, pericardial effusion, evidence of ischemia or wall motion abnormalities, abnormal diastolic or systolic function, and other. RESULTS: Of 539 transthoracic echocardiograms completed on 478 individuals who were pregnant or in the 12-week postpartum period, 96 (17.8%) had an indication of palpitations, and 32 (5.9%) had an indication of dyspnea. Abnormal findings were seen in 21.9% of patients with palpitations and in 34.4% of patients with dyspnea. In patients with palpitations who had abnormal findings, 33.3% had congenital heart disease; 33.3% had mild valvular disease, including mitral valve prolapse; 19.0% had a pericardial effusion; and 14.3% had evidence of ischemia or wall motion defects. Abnormal transthoracic echocardiogram findings in the dyspnea cohort included ischemia or wall motion defects (27.3%), mild valvular disease or mitral valve prolapse (36.4%), and abnormal systolic or diastolic function (36.4%). CONCLUSION: Many of the transthoracic echocardiograms completed for patients with dyspnea or palpitations identified no structural abnormality; however, in 1 of 3 to 1 of 4 patients, underlying structural heart disease was identified. Although some of these abnormalities were unlikely to change delivery plans, such as mild valvular disease or small effusions, other abnormalities, such as ischemia, congenital abnormalities, and abnormal systolic or diastolic function, were likely to have implications for pregnancy and postpartum management.

ETS transcription factors regulate precise matrix metalloproteinase expression and follicle rupture in Drosophila.

Drosophila matrix metalloproteinase 2 (MMP2) is specifically expressed in posterior follicle cells of stage-14 egg chambers (mature follicles) and is crucial for the breakdown of the follicular wall during ovulation, a process that is highly conserved from flies to mammals. The factors that regulate spatiotemporal expression of MMP2 in follicle cells remain unknown. Here, we demonstrate crucial roles for the ETS-family transcriptional activator Pointed (Pnt) and its endogenous repressor Yan in the regulation of MMP2 expression. We found that Pnt is expressed in posterior follicle cells and overlaps with MMP2 expression in mature follicles. Genetic analysis demonstrated that pnt is both required and sufficient for MMP2 expression in follicle cells. In addition, Yan was temporally upregulated in stage-13 follicle cells to fine-tune Pnt activity and MMP2 expression. Furthermore, we identified a 1.1 kb core enhancer that is responsible for the spatiotemporal expression of MMP2 and contains multiple pnt/yan binding motifs. Mutation of pnt/yan binding sites significantly impaired the Mmp2 enhancer activity. Our data reveal a mechanism of transcriptional regulation of Mmp2 expression in Drosophila ovulation, which could be conserved in other biological systems.

Hypertension and contraceptive use among women of child-bearing age in the United States from 2001 to 2018.

BACKGROUND: Hypertension (HTN) in pregnancy is a leading cause of maternal mortality in the United States. Contraception is widely used, and estrogen-based combined hormonal forms are known to increase blood pressure (BP). With nearly half of pregnancies unplanned and many antihypertensive medications teratogenic, appropriate contraception is critical in child-bearing age women with HTN. METHODS: Using the National Health and Nutrition Examination Surveys (NHANES) from 2001 to 2018, we evaluated contraception and antihypertensive medication use in women of child-bearing age (20-50 years). Women who had undergone sterilization or menopause were excluded. HTN was defined based on a self-reported provider diagnosis and BP ≥130/80 mm Hg or antihypertensive medication use. Contraception included non-barrier methods (pills/patch/ring, injections, long-acting reversible contraceptives) or consistent condom use. Multivariable logistic regression was used to model the odds of contraception use. Temporal trends in contraception use were reported. RESULTS: Of the 8726 women, 12.4% had HTN with mean age (standard error) 36.0 (0.3) years. In women with HTN, 9.2% used non-barrier contraception and 10.4% used condoms only. Over half (52.7%) of women with HTN on antihypertensive medications were taking medications contraindicated in pregnancy, with no difference seen by contraceptive status. In logistic regression models, contraceptive use was lower in the older-aged women. In women with HTN on non-barrier contraception, combined hormonal contraceptive use declined, from 100% (2001-2006) to 81.4% (2013-2018, P < 0.001). CONCLUSIONS: Many women with self-reported HTN are not using adequate contraception. Of the small proportion on non-barrier contraceptives, the majority are using estrogen-based, BP-raising methods.
