Pre-diagnosis Dairy Product Intake and Ovarian Cancer Mortality: Results From the Ovarian Cancer Follow-Up Study (OOPS).

ABSTRACT: Background: Dairy product consumption is associated with ovarian cancer (OC) incidence. However, limited evidence is available on its influence on OC mortality. Methods: The association between pre-diagnostic dairy product intake and OC mortality was investigated in the OC follow-up study, which included a hospital-based cohort (n = 853) of women diagnosed with epithelial OC between 2015 and 2020. Pre-diagnosis diet information was collected using a validated food frequency questionnaire. Deaths were ascertained up to March 31, 2021 via death registry linkage. Cox proportional hazards model was used to estimate the adjusted hazard ratio (HR) and 95% confidence interval (CI) for the aforementioned association. Results: A total of 130 women died during the median follow-up of 37.2 months (interquartile: 24.7-50.2 months). Comparisons of highest to lowest tertile intake showed that pre-diagnosis dairy product use was associated with total OC mortality (HR = 2.03, 95% CI = 1.21-3.40, p trend = 0.06). In addition, short survival was separately associated with protein (HR = 2.09, 95% CI = 1.25-3.49, p trend < 0.05), fat (HR = 2.16, 95% CI = 1.30-3.61, p trend < 0.05), and calcium (HR = 2.03, 95% CI = 1.21-3.4, p trend = 0.06) from dairy intake. Similar positive magnitudes were observed for menopausal status, residual lesions, histological type, and body mass index, although not all of these factors showed statistical significance. Conclusion: Pre-diagnosis dairy product consumption, including protein, fat, and calcium from dairy intake, was associated with higher mortality among OC survivors.

Project description:Objective: Analyze the ultrasound features, single nucleotide polymorphism microarray (SNP-array) outcomes, pregnancy results, and follow-up data of fetuses with Xp22.31 deletions or duplications in mid to late pregnancy. Methods: A retrospective analysis was carried out on 10 cases diagnosed with Xp22.31 deletions and 11 cases with duplications, identified through single nucleotide polymorphism microarray (SNP-array) testing. The analysis focused on assessing ultrasound abnormalities, tracing parental origins, pregnancy outcomes, and postnatal follow-up conditions. Results: The deletion sizes in the 10 deletion cases ranged from 913 Kb to 1.81 Mb, while the duplication sizes in the 11 duplication cases ranged from 1.29 Mb to 2.35 Mb, encompassing 9 OMIM genes including STS, ANOS1, DXS1283E, VCS3B, and HDHD1A. Among the fetuses with deletions, four cases (40.0%, 4/10) exhibited ultrasound abnormalities, which included cardiovascular system malformations, lateral ventriculomegaly, clubfoot, increased nuchal translucency, and polyhydramnios. Notably, Case 5 involved a fetus with complex multi-organ malformations, including bilateral ventriculomegaly, a ventricular septal defect, and clubfoot. Among the 11 cases of duplications, three cases (27.3%, 3/11) exhibited ultrasound abnormalities, primarily featuring cardiovascular malformations, ventriculomegaly, and polyhydramnios. Of the 10 deletion cases, eight underwent parental origin testing, with seven cases inherited (six maternal and one paternal) and one case of de novo mutation. Among the 11 duplication cases, eight underwent parental origin testing, with seven cases being inherited (four maternal and three paternal) and one case representing a de novo mutation. Of the 10 deletion cases, six chose to terminate the pregnancy, while four decided to continue. Follow-up revealed that Case 6 was diagnosed with STS ichthyosis shortly after birth, and the sbling of Case 3 and Case 10 exhibited delayed walking and speech development. In the duplication group, one case opted for termination of pregnancy, while 10 continued with their pregnancies. Follow-up identified that Case 18 exhibited delayed walking and speech development. Conclusion: This study provides a preliminary assessment of the genotypes and phenotypes of fetuses with Xp22.31 deletions /duplications, expanding the phenotypic spectrum of Xp22.31 deletions /duplications syndrome. The findings indicate that prenatal Xp22.31 deletions in male fetuses are likely to manifest as STS ichthyosis after birth. Xp22.31 deletions and duplications may be associated with cardiovascular malformations. For fetuses with Xp22.31 deletions /duplications that appear phenotypically normal prenatally, postnatal monitoring of their neurological development is crucial.
