Abnormal uterine bleeding types according to the PALM-COEIN FIGO classification in a medically underserved American community

Objective: To describe the distribution of abnormal uterine bleeding (AUB) type according to the polyp (AUB-P); adenomyosis (AUB-A); leiomyoma (AUB-L); malignancy and hyperplasia (AUB-M); coagulopathy (AUB-C); ovulatory dysfunction (AUB-O); endometrial (AUB-E); iatrogenic (AUB-I); and not yet classified International Federation of Gynecology and Obstetrics classification system in a medically underserved American inner-city population. Our secondary objective was to find an association between risk factors and type of AUB. Material and Methods: We conducted a descriptive cross-sectional analysis at our outpatient women's health clinic located in the Bronx, New York City, from November 2016 to December 2019. Results: Among 390 patients, the most common AUB type was AUB-L (n=185, 47.4%), followed AUB-P (n=100, 25.6%), AUB-A (n=55, 14.1%), AUB-O (n=19, 4.9%), AUB-M (n=15, 3.8%), AUB-E (n=14, 3.6%) and AUB-I (n=2, 0.5%). Race was distributed as follows: Hispanic (68.2%), Black (25.9%), Caucasian (3.3%), and Asian (2.1%). Comorbidities included hypertension (36.4%), diabetes (15.6%), and thyroid disease (6.9%). The median age at diagnosis was significantly higher in AUB-M (59 years old, p<0.001), AUB-P (52.5 years old, p<0.001), AUB-E (51.5 years old, p=0.001) compared to AUB-L (46 years old). The median body mass index (BMI) was significantly higher in AUB-E (34.2 kg/m2, p=0.048) and AUB-O (32.6 kg/m2, p=0.038) compared to AUB-L (30 kg/m2). Race was equally distributed among the AUB types. AUB-M (66.6%, p=0.002), AUB-E (57.1%, p=0.022), AUB-P (47%, p<0.001), and AUB-A (30.8%, p<0.001), had statistically significantly more cases of hypertension compared to AUB-L (28.1%). AUB-P (27%, p<0.001), AUB-M (26.6%, p=0.025), AUB-E (35.7%, p=0.001) and AUB-A (9%, p<0.001) had more patients with diabetes mellitus (DM) than AUB-L (3.3%). Conclusion: In an American population of medically underserved patients, the most common cause of AUB was leiomyoma and the most common race was Hispanic. Women with AUB-L were younger, with lower BMI, and with fewer cases of hypertension and DM when compared to other types of AUB.

Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio in Twins Compared with Singletons.

OBJECTIVES: It is well known that twin pregnancies confer a high degree of adverse perinatal outcomes. Fetal growth restriction, preterm labor/delivery, and hypertensive disorders of pregnancy are among the causal etiologies associated. Hematologic parameters, specifically, the neutrophil:lymphocyte ratio (NLR), the platelet:lymphocyte ratio (PLR), and some of the routine complete blood cell count components denote a peculiar inflammatory and immunologic profile and have been used as clinical markers for specific obstetric syndromes. To our knowledge, no study has ever evaluated NLR/PLR in twins as a distinct population from singletons. Our primary objective was to analyze NLR/PLR in twins compared with singletons. Our secondary objective was to compare white blood cells, neutrophils, lymphocytes, and platelets between twins and singletons. METHODS: We conducted a retrospective case-control study comparing NLR/PLR markers in twin gestations (dichorionic/diamniotic and monochorionic/dichorionic) versus singleton pregnancies, from January 2019 to April 2020. We excluded pregnancies with potential confounding factors such as human immunodeficiency virus, chronic hypertension, smoking, pregestational diabetes mellitus, or cases with miscarriage/intrauterine fetal demise. We included twin pregnancies (two fetuses) as cases and singletons as controls. RESULTS: We recruited 29 twins and 29 singletons, matched for age, body mass index, and parity. NLR was statistically significantly higher in the first trimester in twins compared with singletons (3.3 vs 2.7, P < 0.01) and the platelet value was lower in the second trimester in twins compared with singletons (199 vs 251, P = 0.01). CONCLUSIONS: We speculate that a decrease in NLR from the first to the second trimester and a decrease in platelet in the second trimester reflect both the physiologic inflammatory/immune reaction of early pregnancy and denote a vital response for the development of normal placentation in twin gestations.
