Article Abstract
Purpose: Currently, there is controversy surrounding the association between dietary fatty acids (FAs) and ovarian cancer (OC) risk. We aimed to elucidate the aforementioned topic using data from a large cohort.
Methods: Women participating in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial were included in this study. The dietary information of participants was collected through the diet history questionnaire. Multivariable Cox proportional hazards regression models incorporating restricted cubic splines were constructed to explore the association between dietary FAs intake and the incidence of OC.
Results: Among 50,614 participants in the present study, a total of 277 cases of ovarian cancer were diagnosed. The median follow-up time was 9.44 years. Non-significant association between total FAs intake and risk of OC was observed (non-linear P = 0.060). Compared to the median of total FAs intake, hazard ratios were 1.68 (95% CI: 1.10-2.58) and 1.45 (95% CI: 1.05-1.99) for the 5th percentile and 10th percentile, respectively, while consuming more than the median failed to show significant findings. Similar results were found in the analyses of different types (saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids) and sources (animals and plants) of dietary FAs.
Conclusion: Inadequate consumption of various types and sources of dietary FAs might be associated with an increased risk of OC.

It is helpful for diagnostic purposes to improve our current knowledge of gut development and serum biochemistry in young piglets. This study investigated serum biochemistry, and gut site-specific patterns of short-chain fatty acids (SCFA) and expression of genes related to barrier function, innate immune response, antioxidative status and sensing of fatty and bile acids in suckling and newly weaned piglets. The experiment consisted of two replicate batches with 10 litters each.

High-fat foods are decomposed into fatty acids during digestion and absorption, primarily occurring in the gastrointestinal tract, and numerous studies have indicated that long-term high-fat diets significantly increase the incidence of intestinal disorders. As a critical intestinal hormone, serotonin (5-hydroxytryptamine, 5-HT) is involved in regulating intestinal peristalsis, secretion, and visceral sensitivity. However, due to the lack of methods capable of reproducing intestinal mechanical activities and in situ monitoring of 5-HT levels, the influence of high-fat diets on intestinal 5-HT release remains unclear.

Purpose Of The Review: This review aimed to summarize current evidence on the effectiveness of medical nutrition therapy (MNT) in the management of obesity and endometriosis, with a focus on dietary patterns such as the Mediterranean and Ketogenic diets, as well as nutritional supplementation. Additionally, it highlights the central role of the clinical nutritionist in implementing individualized, evidence-based interventions within multidisciplinary care.
Recent Findings: Although the literature reports the existence of an inverse relationship between risk of endometriosis and body mass index, clinical evidence jointly reports that a condition of obesity is associated with greater disease severity.

The esterase gene encoding EstJN1 of Clostridium butyricum, which was isolated from the pit cellar of Chinese liquor facility, was expressed. EstJN1 was identified as a novel GDSL esterase belonging to family II. The enzyme demonstrated a marked substrate preference for p-nitrophenyl butyrate, with optimal activity at a temperature of 40 ℃ and a pH of 7.
