Identifying and characterizing antimicrobial producing Burkholderia from medicinal plant rhizospheres and soil in the Western Ghats, India.

The Burkholderia genus is a diverse group of Gram-negative bacteria found in soil, water, man-made products, plants, animals and as opportunistic pathogens in multiple hosts. The Burkholderia cepacia complex (Bcc) is a notorious group of Burkholderia species which can cause devastating infections in individuals with cystic fibrosis (CF). The biosynthetic capacity of Burkholderia species is substantial and has made the genus an interesting source for the discovery of specialized metabolites. This research sought to expand the understanding of Burkholderia diversity in the natural environment and the capability of this group to produce antimicrobial specialized metabolites. Bacteria were isolated from the rhizosphere of medicinal plants in the Western Ghats, India, and purified into a collection of 73 environmental isolates. Sequencing of recA and 16S rRNA genes identified 35 Burkholderia strains, which all grouped in the Burkholderia cepacia complex (Bcc). Seven B. cenocepacia strains were from the recA IIIA lineage, a group of virulent strains for which no clear environmental source has been defined. Draft genome sequences were obtained for 34 Burkholderia strains and used to carry out multiple phylogenomic analyses. Four known Bcc species groups and 5 putative novel Bcc taxa were found within the collection. Comparative genomic analysis of the 7 environmental B. cenocepacia IIIA strains against 32 well characterized reference genomes revealed they were closely related to a globally spread and virulent B. cenocepacia sequence type, ST-32. Antimicrobial activity screening revealed that 26 of the 35 Burkholderia strains were antagonistic towards other human and plant pathogenic microbes. Genome mining and chemical analysis of bioactive strains led to the discovery of the first collimonin producing Burkholderia, and the first enacyloxin-producing B. ubonensis strains, providing further novel insights into the biosynthetic potential of the Burkholderia genus

The burden of vulvovaginal atrophy on women's daily living: implications on quality of life from a face-to-face real-life survey

Objective: This subanalysis of the European Vulvovaginal Epidemiology Survey study aimed to assess the correlation of vulvovaginal atrophy (VVA) symptoms and severity, when confirmed by objective gynecologic examination, with the quality of life of postmenopausal women. Methods: Women aged 45 to 75 years with confirmation of last menstrual period more than 12 months before, who attended menopause or gynecology centers, were included. Those women had at least one VVA symptom filled in a group of questionnaires, including EuroQol-EQ-5D-3L and Day-to-Day Impact of Vaginal Aging (DIVA). To confirm the VVA diagnosis, an objective gynecologic examination was also performed. Results: Of a total of 2,160 evaluable women, 66.3%, 30.5%, and 11.2% suffered from severe vaginal, vulvar, and urinary symptoms, respectively. VVA was confirmed in more than 90% of the participants. Mean (±SD) EQ-5D-3L score was 0.892 ± 0.144 and mean (±SD) score on the associated visual analog scale was 71.7 ± 16.0. Mean (±SD) DIVA score was 0.922 ± 0.653. For both EQ-5D-3L and DIVA, the overall scores and most of the dimensions/components were statistically significantly worse for women with severe VVA symptoms (vulvar and urinary) compared with women not affected by severe symptoms. Quality of life questionnaires showed worse scores in women where the diagnosis of VVA was confirmed by gynecologic examination. Conclusions: Severe VVA symptoms showed a direct association with worse quality of life in postmenopausal women. This important effect on the quality of life of many women should be recognized as equivalent to those from other conditions and pathologies of which there is greater awareness

Symptom severity and quality of life in the management of vulvovaginal atrophy in postmenopausal women

Objectives: To evaluate the association between treatments for vulvovaginal atrophy (VVA) and symptom frequency and severity, quality of life (QoL) and sexual functioning in postmenopausal women.Study design: Cross-sectional survey conducted in postmenopausal women aged 45-75 years. Data on demographic and clinical variables, as well as vaginal, vulvar and urinary symptoms were collected. The EuroQoL questionnaire (EQ5D3L), the Day-to-Day Impact of Vaginal Aging (DIVA), the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale - revised (FSDS-R) were filled out.Main outcome measures: Association between treatments for VVA and symptom frequency.Results: Women on VVA treatment presented with more severe symptoms. The sexual function score was higher in the treated women (FSFI: 15.6 vs 16.7; p = 0.010), as was the score for sexual distress (FSDS-R: 9.2 vs 12.3, p < 0.0005). The systemic hormone group presented with fewer VVA symptoms, lower vaginal impact (DIVA), and better sexual function (FSFI and FSDS-R) and vaginal health. The rates of sexual distress and vulvar atrophy were higher in the non-hormonal treatment group. No significant differences were found according to treatment duration.Conclusions: Postmenopausal women with VVA receiving treatment complained of more severe symptoms than those untreated. Women on systemic treatment had fewer and milder VVA symptoms and presented with better vaginal and vulvar health than women on other treatments. Many women request effective local treatment too late, when VVA symptoms are already severe. Our data suggest that VVA treatments should ideally be initiated when symptoms commence and cause distress, rather than later, when symptoms may have become more severe and even a cause of intolerable distress for the woman
