Triclosan

BACKGROUND: Triclosan is an endocrine-disrupting chemical, but associations with pubertal outcomes remain unclear. We examined associations of gestational and childhood triclosan with adolescent hormone concentrations and pubertal stage. METHODS: We quantified urinary triclosan concentrations twice during pregnancy and seven times between birth and 12 years in participants recruited from Cincinnati, OH (2003-2006). We averaged concentrations across pregnancy and childhood and separately considered individual exposure periods in multiple informant models...

It has been a challenge to prepared polyether block amide (PEBA) fibrous membrane via solution electrospinning. The only few reported methods though involved hazardous solvents and surfactants which were against the principle of green chemistry. In this work, uniform fibrous membrane of PEBA was successfully fabricated by solution electrospinning with a bio-based solvent dihydrolevoglucosenone (Cyrene). To further improve the mechanical strength and adsorption performance of the PEBA membrane, a hierarchical magnesium hydrogen phosphate (MgHPO4 ·1...

Individual typical endocrine-disrupting chemicals (EDCs), including organophosphate triesters (OPEs), parabens, triclosan (TCS), bisphenols, benzophenones (BPs), phthalates (PAEs), and synthetic phenolic antioxidants (SPAs), are associated with renal dysfunction. However, the combined effects and underlying mechanisms of mixed EDC exposure on renal function remain unclear. Two hundred ninety-nine adult participants were enrolled in the cross-sectional survey conducted in Guangzhou, China. Urinary levels of 7 OPEs, 6 parabens, TCS, 14 bisphenols, 8 BPs, 15 PAEs, 4 SPAs, and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were determined, and estimated glomerular filtration rate (eGFR) was served as the outcome index...

PURPOSE: We assessed clinical outcomes of patients undergoing open hernia repair using STRATAFIX™ Symmetric, a barbed triclosan-coated suture (TCS; Ethicon), versus conventional polydioxanone suture (PDS) for abdominal wall closure. METHODS: This single-center retrospective cohort study identified patients undergoing hernia repair. The site used PDS from 2013 to 2016 and switched exclusively to barbed TCS in 2017. Outcomes were assessed at 30, 60, and 90 days...

Recently, there has been a noticeable increase in disorders of the female reproductive system, accompanied by a rise in adverse pregnancy outcomes. This trend is increasingly being linked to environmental pollution, particularly through the lens of Endocrine Disrupting Chemicals (EDCs). These external agents disrupt natural processes of hormones, including synthesis, metabolism, secretion, transport, binding, as well as elimination. These disruptions can significantly impair human reproductive functions. A wealth of animal studies and epidemiological research indicates that exposure to toxic environmental factors can interfere with the endocrine system's normal functioning, resulting in negative reproductive outcomes...

Emerging micropollutants, such as pharmaceuticals and microplastics (MPs), have become a pressing water environmental concern. The aim of this study is to synthesize chitosan sponges using graphene oxide (GO) and genipin (GP) for the removal of pharmaceuticals (diclofenac (DCF) and triclosan (TCS)) and MPs, verify their adsorption mechanisms, evaluate the effects of temperature, pH, and salinity on their adsorption capacities, and determine their reusability. The GO5 /CS/GP sponge exhibited a macroporous nature (porosity = 95%, density = 32...

The concentrations and distribution patterns of three typical pharmaceuticals and personal care products (PPCPs) in water and sediment samples obtained from Danjiangkou Reservoir during two seasonal sampling periods were studied to determine their impact on water quality. The temporal and spatial variations in concentrations measured were analyzed and related to ecological risks with data obtained during the mean-flow period (in June) and the dry period (in November). We found a high detection rate of ketoprofen (KTP) in water samples from Danjiangkou Reservoir; the concentrations ranged from not detected (ND) to 46...

INTRODUCTION: Emergent laparotomy is associated with significant wound complications including surgical site infections (SSI) and fascial dehiscence (FD). Triclosan-coated barbed suture (TCB) for fascial closure has been shown to reduce local complications but primarily in elective settings. We sought to evaluate the effect of TCB emergency laparotomy fascial closure on major wound complications. METHODS: Adult patients undergoing emergency laparotomy were prospectively evaluated over 1-year...

Microplastic (MP) contamination is in the spotlight today, yet knowledge of their interaction with other organic contaminants in the soil environment is limited. Concerns extend to endocrine disrupting chemicals (EDCs), known for their potential to interfere with the hormonal systems of organisms and for their persistence and widespread presence in the environment. In this study, the most frequently occurring EDCs were monitored both in alluvial soil and in soil contaminated with different MPs commonly found in soil media, polyethylene, polyamide, and polystyrene...

Here, we present genome sequences of five Stenotrophomonas indicatrix strains, isolated from agricultural soil. Stenotrophomonas strains are commonly associated with the rhizosphere and are well-known for their ability to degrade xenobiotics. Yet, to date, knowledge about S. indicatrix is limited.

BACKGROUND: Interest in surgical site infections (SSI) has been sustained over the years because its occurrence may be ruinous to the overall success of surgical operations. The use of antimicrobial suture has been associated with a reduction in SSI, but its role in open appendectomy has not been evaluated. OBJECTIVE: This study compared the effect of fascia closure with triclosan-coated polydioxanone (PDS) with plain PDS on SSI in appendectomy wounds. MATERIALS AND METHODS: Ninety-three consecutive patients who had open appendectomy for uncomplicated acute appendicitis were randomised to either have fascia closure with triclosan-coated PDS (TCS) or plain PDS...

AIM: Triclosan is an antiseptic substance that has been shown in preclinical studies to reduce bacterial load in the wound and slow bacterial growth by inhibiting fatty acid synthesis. It is claimed that the coating protects against colonization of the tissue around the suture. This study aimed to compare the safety and efficacy of triclosan-coated polydioxanone versus uncoated polydioxanone sutures for the prevention of surgical site infections (SSIs) following hypospadias repair in children...

Preterm birth in humans (PTB), defined as birth prior to 37 weeks of gestation, is one of the most important causes of neonatal morbidity and mortality and is associated with adverse health outcomes later in life. Attributed to many different etiological factors, estimated 15.1 million or 11.1% of births each year are preterm, which is more than 1 per 10 livebirths globally. Environmental pollution is a well-established risk factor that could influence the pathogenesis of PTB. Increasing evidence has shown an association between maternal exposure to endocrine disrupting chemicals (EDCs) and PTB...
