The role of gut microbiota in adolescent depression: Insights from adverse childhood experiences.

Background: Depression has become a leading global mental health disorder, with a rising prevalence of 15-20 % among adolescents. Emerging evidence suggests that adolescent depression may constitute a distinct subtype, differing clinically and neurobiologically from adult presentations. The gut microbiota's role in psychiatric disorders has garnered increasing attention, as dysbiosis may modulate behavior and mood via the microbiota-gut-brain axis, potentially contributing to depressive pathogenesis.

Microbiota composition-based donor selection affects FMT efficacy in a murine colitis model.

Background: Growing evidence links gut microbial dysbiosis to inflammatory bowel disease (IBD) pathogenesis, establishing fecal microbiota transplantation (FMT) as a microbiota-targeted therapy; however, variable outcomes in randomized trials highlight the need to identify compositional features of donor microbiota associated with FMT efficacy.

Objective: This study aimed to investigate how the composition of the donor gut microbiota influences the therapeutic efficacy of FMT in IBD.

Method: Fecal DNA from 39 IBD patients and 42 healthy donors was analyzed via 16S rRNA sequencing.

Investigating potential links between gut microbiome, clinical parameters, and mortality in long-living male patients receiving multi-drug therapy.

Background And Aims: Multimorbidity and polypharmacy are common in long-living patients and have been linked to alterations in gut microbiota. However, the prognostic relevance of these microbiota changes remains unclear in this population. We hypothesized that clinical parameters and gut microbial profiles are associated with survival outcomes.

The characteristics of tissue microbiota in different anatomical locations and different tissue types of the colorectum in patients with colorectal cancer.

The gut microbiota is intricately associated with the onset and progression of colorectal cancer (CRC), leading to significant interest in developing prevention and treatment strategies that leverage gut microbiota. In this study, we collected 57 samples from 19 CRC patients, comprising cancerous tissue, paracancerous tissue, and normal mucosa. Utilizing metagenomic sequencing and bioinformatics analysis, we identified differences in the microbiomes and their functional characteristics across the various tissue types.

Structural and functional alteration of the gut microbiomes in ICU staff: a cross-sectional analysis.

Background: 16S rRNA sequencing has revealed structural alterations in the gut microbiomes of medical workers, particularly those working in intensive care unit (ICU). This study aims to further compare the taxonomic and functional characteristics of gut microbiomes between ICU staff and non-medical individuals using metagenomic sequencing.

Methods: A prospective cross-sectional cohort study was conducted, fecal samples from 39 individuals in each group-ICU staff and non-medical subjects were analyzed using metagenomic sequencing.

Fecal microbiota transplantation restores gut microbiota diversity in children with active Crohn's disease: a prospective trial.

Background: Clinical data on oral fecal microbiota transplantation (FMT), a promising therapy for Crohn's disease (CD), are limited. Herein, we determined the short-term safety and feasibility of FMT for pediatric patients with active CD.

Methods: In this open-label, parallel-group, single-center prospective trial, patients with active CD were treated with oral FMT capsules combined with partial enteral nutrition (PEN) (80%).

Identification of disease-specific gut microbial markers in vitiligo.

There is a potential correlation between vitiligo and gut microbiota, although research in this area is currently limited. The research employed high-throughput sequencing of 16S rRNA to examine the gut microbiome in the stool samples of 49 individuals with vitiligo and 49 without the condition. The study encompassed four comparison groups: (1) DI (disease) group vs.

Gut bacteria Prevotellaceae related lithocholic acid metabolism promotes colonic inflammation.

Background: The conversion of primary bile acids to secondary bile acids by the gut microbiota has been implicated in colonic inflammation. This study investigated the role of gut microbiota related bile acid metabolism in colonic inflammation in both patients with inflammatory bowel disease (IBD) and a murine model of dextran sulfate sodium (DSS)-induced colitis.

Methods: Bile acids in fecal samples from patients with IBD and DSS-induced colitis mice, with and without antibiotic treatment, were analyzed using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS).

Effect of Gegen Qinlian Decoction on the regulation of gut microbiota and metabolites in type II diabetic rats.

Gegen Qinlian Decoction (GGQLT) is a traditional Chinese herbal medicine that has been reported to have a significant therapeutic effect in the management of type II diabetes mellitus (T2DM). In this study, we constructed a T2DM rat model by feeding a high-fat diet and injecting streptozotocin (STZ) and tested the effects of feeding GGQLT and fecal transplantation on the physiological indices, microbiota, and metabolism of rats. The results showed that the administration of GGQLT can significantly improve the growth performance of rats and has a remarkable antihyperlipidemic effect.

Age over sex: evaluating gut microbiota differences in healthy Chinese populations.

Age and gender have been recognized as two pivotal covariates affecting the composition of the gut microbiota. However, their mediated variations in microbiota seem to be inconsistent across different countries and races. In this study, 613 individuals, whom we referred to as the "healthy" population, were selected from 1,018 volunteers through rigorous selection using 16S rRNA sequencing.

Gut microbiota characteristics of colorectal cancer patients in Hubei, China, and differences with cohorts from other Chinese regions.

The research on the correlation or causality between gut microbiota and the occurrence, development, and treatment of colorectal cancer (CRC) is receiving increasing emphasis. At the same time, the incidence and mortality of colorectal cancer vary among individuals and regions, as does the gut microbiota. In order to gain a better understanding of the characteristics of the gut microbiota in CRC patients and the differences between different regions, we initially compared the gut microbiota of 25 CRC patients and 26 healthy controls in the central region of China (Hubei Province) using 16S rRNA high-throughput sequencing technology.

Successful allogeneic fecal microbiota transplantation for severe diversion colitis: a case report.

Ileostomy diverts the flow of feces, which can result in malnutrition in the distal part of the intestine. The diversity of the gut microbiota consequently decreases, ultimately leading to intestinal dysbiosis and dysfunction. This condition can readily result in diversion colitis (DC).

Structural characteristics of gut microbiota in longevity from Changshou town, Hubei, China.

The gut microbiota (GM) and its potential functions play a crucial role in maintaining host health and longevity. The aim of this study was to investigate the potential relationship between GM and longevity. We collected fecal samples from 92 healthy volunteers (middle-aged and elderly: 43-79 years old; longevity: ≥ 90 years old) from Changshou Town, Zhongxiang City, Hubei, China.

Case Report: Fecal Microbiota Transplantation for the Treatment of Generalized Eczema Occurring After COVID-19 Vaccination.

Adverse skin reactions caused by the COVID-19 vaccine have attracted considerable attention. As we all know, the development mechanism of some skin diseases is related to the gut and skin microbiome. A 78-year-old male patient who received the COVID-19 vaccine developed generalized eczema with multiple dense black patches over the body, a widespread rash, erosion, and scabs on his limbs, as well as facial edema.
