Pelvic venous disorders (PeVD) are not well represented in obstetrics and gynaecology journals.

Background: Pelvic venous disorders (PeVD), previously "Pelvic congestion syndrome (PCS)" is usually defined as a female health problem. However, it is our impression that gynaecologists rarely recognise this condition, and most of the research interest appears to be by vascular and venous surgeons, and radiologists. The aim of this study was to investigate if there was evidence to support this view.

Phenylacetic acid metabolic genes are associated with dominant circulating clone 1.

Unlabelled: (MAB) causes lung infections in people with cystic fibrosis (pwCF), and infecting strains show significant genetic variability both between and within individuals. MAB isolates can be divided into dominant clonal clusters (DCCs) or non-clustering groups and can present as smooth or rough colonies on agar plates. Both DCCs and the rough colony morphology have been linked to increased pathogenicity, but the mechanisms are unclear.

Use of commercial or indigenous yeast impacts the transcriptome during wine fermentation.

Unlabelled: Grapes have been cultivated for wine production for millennia. Wine production involves a complex biochemical process where sugars in grape must are converted into alcohol and other compounds by microbial fermentation, primarily by the yeast . Commercially available strains are often used in winemaking, but indigenous (native) strains are gaining attention for their potential to contribute unique flavors.

Towards improved biofilm models.

Biofilms are complex microbial communities that have a critical function in many natural ecosystems, industrial settings as well as in recurrent and chronic infections. Biofilms are highly heterogeneous and dynamic assemblages that display complex responses to varying environmental factors, and those properties present substantial challenges for their study and control. In recent years, there has been a growing interest in developing improved biofilm models to offer more precise and comprehensive representations of these intricate systems.

Improvement of a mouse infection model to capture chronic physiology in cystic fibrosis.

Laboratory models are central to microbiology research, advancing the understanding of bacterial physiology by mimicking natural environments, from soil to the human microbiome. When studying host-bacteria interactions, animal models enable investigators to examine bacterial dynamics associated with a host, and in the case of human infections, animal models are necessary to translate basic research into clinical treatments. Efforts toward improving animal infection models are typically based on reproducing host genotypes/phenotypes and disease manifestations, leaving a gap in how well the physiology of microbes reflects their behavior in a human host.

Convergent evolution in toxin detection and resistance provides evidence for conserved bacterial-fungal interactions.

Microbes rarely exist in isolation and instead form complex polymicrobial communities. As a result, microbes have developed intricate offensive and defensive strategies that enhance their fitness in these complex communities. Thus, identifying and understanding the molecular mechanisms controlling polymicrobial interactions is critical for understanding the function of microbial communities.

Experimental evolution of gene essentiality in bacteria.

Essential gene products carry out fundamental cellular activities in interaction with other components. However, the lack of essential gene mutants and appropriate methodologies to link essential gene functions with their partners poses significant challenges. Here, we have generated deletion mutants in 32 genes previously identified as essential, with 23 mutants showing extremely slow growth in the SK36 strain of .

The access and invasiveness-based classification of medical procedures to clarify non-invasive from different forms of minimally invasive and open surgery.

Background: The rapid development of less invasive and traumatic medical procedures has resulted in a mixture of terms used to describe them, without any agreed definition for each. This is confusing to both medical professionals and patients and can lead to unrealistic patient expectations. The aim of this article is to show the current confused nomenclature and to suggest a new, simple classification based on access and invasiveness (AI) that can be applied to any medical procedure.

Guidelines for management of actual or suspected inadvertent intra-arterial injection of sclerosants.

Background: Inadvertent intra-arterial injection of sclerosants is an uncommon adverse event of both ultrasound-guided and direct vision sclerotherapy. This complication can result in significant tissue or limb loss and significant long-term morbidity.

Objectives: To provide recommendations for diagnosis and immediate management of an unintentional intra-arterial injection of sclerosing agents.

A Retrospective Cohort Study of Patient Risk Factors and Pelvic Venous Reflux Patterns on Treatment Outcomes With Pelvic Vein Embolisation.

Objective: To identify the effects of patient risk factors and pelvic venous reflux (PVR) patterns on treatment outcomes of Pelvic Vein Embolisation (PVE) for Pelvic Venous Disorder (PeVD).

Methods: We performed a retrospective cohort review assessing population, intervention, comparison, and outcomes (PICO) for women undergoing PVE for PVR January 2017-January 2021. We identified 190 patients who had completed both questionnaires and who had given consent for their information to be used for research (Median age 46, IQR 40-52).

Evaluating pharmacological THRomboprophylaxis in Individuals undergoing superficial endoVEnous treatment across NHS and private clinics in the UK: a multi-centre, assessor-blind, randomised controlled trial-THRIVE trial.

Introduction: Endovenous therapy is the first choice management for symptomatic varicose veins in NICE guidelines, with 56-70 000 procedures performed annually in the UK. Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a known complication of endovenous therapy, occurring at a rate of up to 3.4%.

Characterization of a new Queuovirinae bacteriophage.

The ESKAPEE pathogen is a common cause of chronic wound and cystic fibrosis lung infections, as well as acute burn and nosocomial infections. Many of these infections are recalcitrant to conventional antibiotic therapies due to both traditional antibiotic resistance mechanisms and antimicrobial tolerance. Recent successes with bacteriophage (phage) therapy to treat chronic human infections have led to a renewed interest in isolating and characterizing new phages.

Metabolic diversity of human macrophages: potential influence on intracellular survival.

is a leading cause of medical device-associated biofilm infections. This is influenced by the ability of biofilm to evade the host immune response, which is partially driven by the anti-inflammatory cytokine interleukin-10 (IL-10). Here, we show that treatment of human monocyte-derived macrophages (HMDMs) with IL-10 enhanced biofilm formation, suggesting that macrophage anti-inflammatory programming likely plays an important role during the transition from planktonic to biofilm growth.

Syncope (fainting on standing from squatting) due to massive venous reflux into lower limb varicose veins - Case report.

A 42-year-old man presented with very large lower limb varicose veins bilaterally and an 8-month history of fainting when standing up from a squatting position. He had been investigated for syncope by a cardiologist with no abnormality found on electrocardiogram, echocardiogram, 24-h electrocardiogram or 48-h blood pressure monitoring. Venous duplex ultrasonography showed bilaterally great saphenous vein reflux, with each vein having a diameter of 23.

Identification of a glutathione transporter in .

Microbes produce a large array of extracellular molecules, which serve as signals and cues to promote polymicrobial interactions and alter the function of microbial communities. This has been particularly well studied in the human oral microbiome, where key metabolites have been shown to impact both health and disease. Here, we used an untargeted mass spectrometry approach to comprehensively assess the extracellular metabolome of the pathogen and the commensal during mono- and co-culture.

Emerging strategies to target virulence in respiratory infections.

is an opportunistic pathogen that is responsible for infections in people living with chronic respiratory conditions, such as cystic fibrosis (CF) and non-CF bronchiectasis (NCFB). Traditionally, in people with chronic respiratory disorders, infection has been managed with a combination of inhaled and intravenous antibiotic therapies. However, due in part to the prolonged use of antibiotics in these people, the emergence of multi-drug resistant strains is a growing concern.

A gene network-driven approach to infer novel pathogenicity-associated genes: application to PAO1.

We present here a new systems-level approach to decipher genetic factors and biological pathways associated with virulence and/or antibiotic treatment of bacterial pathogens. The power of this approach was demonstrated by application to a well-studied pathogen PAO1. Our gene co-expression network-based approach unraveled known and unknown genes and their networks associated with pathogenicity in PAO1.

899 serious adverse events including 13 deaths, 7 strokes, 211 thromboembolic events, and 482 immune reactions: The untold story of cyanoacrylate adhesive closure.

Objective: The aim was to retrieve and analyse the serious adverse events of venous occlusion systems used in cyanoacrylate adhesive closure (CAC) submitted to regulatory agencies.

Methods: The (TPLC) database of the US Food and Drug Administration (FDA), the (DAEN) of the Australian Therapeutic Goods Administration (TGA), and the database of the UK Medicines and Healthcare Products Regulatory Agency (MHRA) were reviewed. Three Freedom of Information (FOI) requests had to be submitted to the MHRA to obtain data.

Participant Reported Improvement in Cellulite by Vari-Pad Apparel and Objective Measurements - A "First Use" Pilot Study.

Background: Cellulite affects 80-90% of post-pubertal females and, although cosmetic, has proven adverse psychological effects. A new compression garment with patented "vari-pad" technology has been developed, aiming to stimulate lymphatic return from the buttocks and thighs. The primary aim of this small pilot study was to assess participant satisfaction after using this garment in the short term and secondarily, to look for any objective improvements.

A Pseudomonas aeruginosa small RNA regulates chronic and acute infection.

The ability to switch between different lifestyles allows bacterial pathogens to thrive in diverse ecological niches. However, a molecular understanding of their lifestyle changes within the human host is lacking. Here, by directly examining bacterial gene expression in human-derived samples, we discover a gene that orchestrates the transition between chronic and acute infection in the opportunistic pathogen Pseudomonas aeruginosa.

Application of a quantitative framework to improve the accuracy of a bacterial infection model.

Laboratory models are critical to basic and translational microbiology research. Models serve multiple purposes, from providing tractable systems to study cell biology to allowing the investigation of inaccessible clinical and environmental ecosystems. Although there is a recognized need for improved model systems, there is a gap in rational approaches to accomplish this goal.

Impact of Polymicrobial Infection on Fitness of Streptococcus gordonii .

Pathogenic microbial ecosystems are often polymicrobial, and interbacterial interactions drive emergent properties of these communities. In the oral cavity, Streptococcus gordonii is a foundational species in the development of plaque biofilms, which can contribute to periodontal disease and, after gaining access to the bloodstream, target remote sites such as heart valves. Here, we used a transposon sequencing (Tn-Seq) library of S.
