AI Article Synopsis
- Serum bile acids levels typically rise after eating, but some dogs have higher levels before eating, which is paradoxical.
- The study aimed to assess whether serum cholecystokinin (CCK) levels relate to these odd bile acid results and if seeing or smelling food affects them.
- Results showed that while CCK levels increased after eating in some dogs, there was no strong link between CCK and atypical bile acid concentrations, and visual or olfactory food stimuli didn't significantly impact bile acids.
Article Abstract
Serum bile acids concentrations rise postprandially. However, some dogs show paradoxical serum bile acids results with higher pre-prandial than post-prandial concentrations. The aim of this study was to evaluate serum cholecystokinin (CCK) concentrations and determine whether they correspond to paradoxical serum bile acids concentrations. In addition, seeing and smelling food was investigated as a possible cause for paradoxical serum bile acids results. Eight healthy dogs owned by volunteers enrolled in this experimental study. Food was withheld from the dogs for 12 h with great care not to expose them to any sight or smell of food. Blood samples were collected at 0, 30, 60, 120, 180, 240, 480 and 720 min after feeding. Food was then withheld again for 24 h, and blood samples were collected at 0, 30, 60, 120, 180, 240, 480 and 720 min after seeing and smelling food. After feeding, serum CCK concentrations increased, but paradoxical serum CCK concentrations were observed in some of dogs, but only one of those had also paradoxical serum bile acids concentrations. After seeing and smelling food, serum CCK and serum bile acids concentrations did not significantly increase. In conclusion, paradoxical serum CCK concentrations can occur in some healthy dogs after feeding. However, no correlation with paradoxical serum bile acids concentrations was found. Seeing or smelling food are unlikely causes for paradoxical serum bile acids concentrations. Additional studies are warranted to further evaluate the relationship of serum CCK and bile acids concentrations in healthy dogs and dogs with gastrointestinal disease.

This primigravid pregnant woman had a new diagnosis of primary biliary cholangitis (PBC) that was treated with a combination of ursodeoxycholic acid (UDCA) and bezafibrate. Pregnancy may unmask underlying chronic hepatic disorders in susceptible women and, in some cases, the associated abnormalities of liver function or increased serum bile acids (hypercholanaemia) can result in significant fetal and maternal risk. Maternal pruritus, with associated sleep deprivation, may cause considerable distress.

To understand the colonization status of Group B Streptococcus (GBS) in the reproductive tract of pregnant women in the Linyi region, the drug resistance, genotype distribution, and molecular epidemiological characteristics of GBS, and to explore the high-risk factors for GBS infection in late-stage pregnant women. A total of 3269 pregnant women at 35-37 weeks of gestation who visited the Obstetrics Department of Linyi Maternal and Child Health Hospital from January 2019 to December 2021 were selected as the study subjects. Vaginal and rectal swabs were collected for GBS culture.

Lactic acid bacteria are widely regarded as safe alternatives to antibiotics in livestock and poultry farming and have probiotic potential. () is a prominent component of pigeon crop microbiota; however, its function is unknown. In this study, a strain of 1003 from pigeon cecum was identified by combining whole genome sequencing and phenotypic analysis, and its safety and probiotic properties were studied.

Psychiatric disorders pose a significant global health challenge, exacerbated by the COVID-19 pandemic and insufficiently addressed by the current treatments. This review explores the emerging role of bile acids and the TGR5 receptor in the pathophysiology of psychiatric conditions, emphasizing their signaling within the gut-brain axis. We detail the synthesis and systemic functions of bile acids, their transformation by gut microbiota, and their impact across various neuropsychiatric disorders, including major depressive disorder, general anxiety disorder, schizophrenia, autism spectrum disorder, and bipolar disorder.
