Objectives: To evaluate maternal and fetal outcomes among women with hyperemesis gravidarum (HG).
Methods: In a university hospital and a research and training hospital, a retrospective cohort study was conducted among women with singleton deliveries between 2003 and 2011. Maternal outcomes evaluated included gestational diabetes, pregnancy-induced hypertension, cesarean delivery. Neonatal outcomes also determined were 5-min Apgar score of less than 7, low birth weight, small for gestational age (SGA), preterm delivery, fetal sex, and stillbirth.
Results: There were no statistical differences in the mean of age, parity, the number of artificial pregnancy, and smoking between two groups. Infants from HG pregnancies manifested similar birth weight (3,121.5 ± 595.4 vs. 3,164 ± 664.5 g) and gestational age (38.1 ± 2.3 vs. 38.1 ± 2.6 weeks), relative to infants from the control group (p = 0.67 and 0.91, respectively). In addition, no statistical significant differences were found in the rates of SGA birth, preterm birth, gestational diabetes, pregnancy-induced hypertension, and adverse fetal outcome between two groups (p > 0.05). Cesarean delivery rates were similar in two groups (31.9% in hyperemesis group vs. 27% in control group, p = 0.49). Comparing the gender of the newborn baby and Apgar scores less than 7 at 5 min, there were no statistically significant differences between two groups (p = 0.16 and 0.42, respectively).
Conclusion: Hyperemesis gravidarum is not associated with adverse pregnancy outcomes.

Objectives: The main objective of this case report is to discuss the differentiation between hyperemesis gravidarum and a brain tumor in the presence of hyperemesis symptoms in the first trimester of pregnancy.
Case Report: A patient was initially diagnosed with hyperemesis gravidarum in early pregnancy and was hospitalized. After hospitalization, cerebral hemorrhage and cerebral hernia due to convulsions occurred.
While most pregnancies are affected by nausea and vomiting, hyperemesis gravidarum (HG) is at the severe end of the clinical spectrum and is associated with dehydration, undernutrition, and adverse maternal, fetal, and child outcomes. Herein we performed a multi-ancestry genome-wide association study (GWAS) of severe nausea and vomiting of pregnancy of 10,974 cases and 461,461 controls across European, Asian, African, and Latino ancestries. We identified ten significantly associated loci, of which six were novel ( , , , , , and and confirmed previous genome-wide significant associations with risk genes , , , and .

Background: Cannabinoid hyperemesis syndrome (CHS) is a syndrome of cyclic nausea and vomiting in the setting of chronic cannabis use. To date, only 11 cases of CHS in pregnancy have been reported.
Case Presentation: We describe two cases of uncontrolled vomiting in pregnancy due to CHS.
Prolonged prothrombin time in hyperemesis gravidarum as an indicator of vitamin K deficiency.

Article Synopsis
- The study investigates the impact of maternal vitamin K deficiency on fetal health, specifically in patients with severe hyperemesis gravidarum.
- Researchers compared coagulation factors in hyperemesis patients with those undergoing other procedures and found significant changes, particularly in prothrombin time.
- Timely vitamin K supplementation can normalize coagulation levels, potentially preventing serious fetal complications related to vitamin K deficiency.
