Effects of a prebiotic formulation on the composition of the faecal microbiota of people with functional constipation.

PURPOSE: Prebiotics are defined as substances which selectively promote beneficial gut microbes leading to a health benefit for the host. Limited trials have been carried out investigating their effect on the microbiota composition of individuals afflicted by functional constipation with equivocal outcomes. In a 21-day randomised, controlled clinical trial involving 61 adults with functional constipation, a prebiotic formulation with partially hydrolysed guar gum and acacia gum as its main ingredients, significantly increased complete spontaneous bowel motions in the treatment group. This follow-up exploratory analysis investigated whether the prebiotic was associated with changes to the composition, richness, and diversity of the faecal microbiota. METHODS: Participants provided a faecal specimen at baseline and on day 21 of the intervention period. Whole genome metagenomic shotgun sequencing comprehensively assessed taxonomic and functional composition of the microbiota. RESULTS: Linear mixed effects regression models adjusted for potential confounders showed a significant reduction in species richness of 28.15 species (95% CI - 49.86, - 6.43) and Shannon diversity of 0.29 units (95% CI - 0.56, - 0.02) over the trial period in the prebiotic group. These changes were not observed in the control group, and functional composition was unchanged in both groups. CONCLUSION: In adults with functional constipation, the intake of a prebiotic formulation was associated with a decline of species richness and Shannon diversity. Further research regarding the associations between prebiotics and the composition and function of the gut microbiota is warranted.

Mental Health Literacy and Education of Complementary Medicine Practitioners: A Cross-Sectional Study.

An estimated 42% of Australians who consult complementary medicine (CM) practitioners have a mental health diagnosis. Preparedness of CM practitioners in managing such diagnoses is currently unknown. A cross-sectional survey of 257 CM practitioners who reported caring for people with a mental health diagnosis. Practitioners' mental health literacy, educational needs, and confidence in the assessment, management, and treatment of mental health-including suicide risk-were analysed. Most (59.1%) participants had no formal qualifications in mental health and 44.3% indicated they had not completed any training in psychological therapies. Only 20% were trained in mindfulness-based techniques or goal setting. Over 50% reported their undergraduate qualification contained insufficient mental health content to prepare them for clinical practice. Over one-half had attended continuing professional education on mental health. Practitioners reported greater confidence in assessing, managing, and treating mental wellbeing over complex mental health disorders and suicide risk. These findings uncovered a deficit in the CM practitioner's surveyed mental health education. As these CM practitioners are a primary point of contact for patients with mental health diagnoses, there is a critical need to expedite skills development in this workforce to support the delivery of safe and effective primary mental health care.

Could pharmacy technicians play a role in supporting the appropriate and safe use of traditional and complementary medicines?

Across the world traditional and complementary medicine (T&CM) product use is prevalent with some countries reporting greater than 50% of the population using these products. T&CM products are primarily self-selected through retail outlets including pharmacies. Pharmacists across the world generally agree they should play a role in ensuring the appropriate and safe use of T&CM products but report being time and resource poor to do so. In this commentary, it is proposed that pharmacy technicians as members of the pharmacy workforce, who with adequate education, and supportive technologies could support pharmacists in providing guidance to consumers and patients about the appropriate and safe use of T&CM products. Pharmacy technicians play a crucial role in the pharmacy workforce, serving as integral members of healthcare teams fulfilling a wide array of tasks essential for the efficient functioning of pharmacies and ensuring the safe dispensation of medications. They have been described by pharmacists as the "the face of the pharmacy" in the community setting and relied on not only for mitigating and triaging problems, but also be primarily responsible for developing rapport, eliciting trust and even loyalty from pharmacy patrons. As such, there is a momentous opportunity for pharmacy technicians to play a role in providing T&CM advice and triaging the need for pharmacists' intervention where harm, or risk of is identified.

The semen microbiome of miniature pony stallions.

CONTEXT: Little is known about the microbial composition of stallion semen. AIMS: To describe the microbiota detected in equine semen of healthy miniature pony stallions. METHODS: Semen specimens were collected using a Missouri artificial vagina at a single time point. PacBio (Pacific Biosciences) genomic DNA sequencing of the 16S rRNA gene was performed on these specimens, following which next-generation microbiome bioinformatics platform QIIME2 was used to process fastq files and analyse the amplicon data. The data were categorised into genus, family, class, order and phylum. KEY RESULTS: Firmicutes and Bacteroidetes phyla predominated (76%), followed by Proteobacteria (15%). Bacteroidales, Clostridiales and Cardiobacteriales predominated the microbial rank of order (86%). Class was mainly composed of Bacteroidia, Clostridia and Gammaproteobacteria (87%), while family was mainly composed of Porphyromonadaceae , Family_XI and Cardiobacteriaceae (62%). At the level of genus, 80% of the abundance was composed of seven genera, namely Porphyromonas, Suttonella, Peptoniphilus, Fastidiosipila, Ezakiella, Petrimonas and an unknown taxon. CONCLUSIONS: The findings indicate that specific microbiota may be characteristic of healthy miniature pony stallions' semen with some inter-individual variations observed. IMPLICATIONS: Larger equine studies involving fertile and infertile subjects could be informed by this study and could explore the relationship of the semen microbiome to male fertility.

Effect of probiotics and prebiotics on the composition of the equine fecal and seminal microbiomes and sperm quality: A pilot study.

Probiotic and prebiotic effects on equine semen and gastrointestinal microbiome composition and sperm quality are unknown. This study aimed to evaluate the effects of pre-, pro- or synbiotic supplementation on fecal and semen microbiome composition and sperm quality parameters of stallions. This Latin square crossover trial involved four miniature pony stallions receiving control diet only, or addition of a pro-, pre- or synbiotic formulation. Full-length 16S rRNA gene amplicon sequencing was used to measure diversity of semen and fecal microbiomes. Total sperm count, total motility, progressive motility, DNA integrity, lipid peroxidation and mitochondrial oxidative stress, biomarkers of sperm quality, were measured after each intervention. A general linear model was employed to analyse and compare microbiome diversity measures and sperm quality data across four time points. Shannon's diversity index (alpha-diversity), and evenness of semen and gastrointestinal microbiomes were significantly different (p<0.001). A trend was observed for prebiotic effects on the diversity indices of the GI microbiome (p= 0.07). No effects of treatments were observed on either semen microbiome or sperm quality. Pre-, pro- and synbiotic supplements showed no negative effect on sperm quality parameters observed. This proof of concept provides preliminary data to inform future studies exploring the relationship between microbiomes and fertility.
