Evaluating the Impact of Laundry Detergents on the Skin Microbiome of Atopic Dermatitis Patients-A Clinical Study.

Background And Aims: Remnants of laundry detergent ingredients are suspected to be in constant contact with the skin. Allergy sufferers need assurance that the chemicals in everyday products do not cause such disruption. The purpose of this study was to evaluate the effects and tolerability of common laundry detergents on the skin microbiome in individuals with atopic dermatitis.

Pessary or cerclage (PC study) to prevent recurrent preterm birth: a non-inferiority, randomised controlled trial.

Background: Previous spontaneous preterm birth (sPTB) is a strong risk indicator for recurrent preterm birth (PTB). Cervical cerclage is an accepted intervention to prevent recurrent PTB in high risk patients. Cervical pessary might be a less invasive alternative.

Objective: To compare the effectiveness of cervical pessary and vaginal progesterone in the prevention of adverse perinatal outcomes and preterm birth in pregnant women of singletons with no prior spontaneous preterm birth at less than 34 weeks' gestation and who have a short cervix of 35 mm or less.

Design: Open label, multicentre, randomised, controlled trial.

Setting: 20 hospitals and five obstetric ultrasound practices in the Netherlands.

A comprehensive approach for evaluating the virucidal performance of domestic laundry detergents under practical conditions.

Aims: We aimed to develop a method to assess the virucidal performance of domestic laundry in a lab-scale washing machine (Rotawash) based on EN 17658.

Methods And Results: For method development, virus recovery was investigated after drying on cotton carriers for three test viruses murine norovirus (MNV), modified vaccinia virus Ankara (MVA), and bovine coronavirus (BCoV), followed by washing simulations in flasks and Rotawash. MNV and MVA demonstrated sufficient recovery from carriers after drying and washing (up to 40°C and 60 min).

Manchester Procedure vs Sacrospinous Hysteropexy for Treatment of Uterine Descent: A Randomized Clinical Trial.

Importance: In many countries, sacrospinous hysteropexy is the most commonly practiced uterus-preserving technique in women undergoing a first operation for pelvic organ prolapse. However, there are no direct comparisons of outcomes after sacrospinous hysteropexy vs an older technique, the Manchester procedure.

Objective: To compare success of sacrospinous hysteropexy vs the Manchester procedure for the surgical treatment of uterine descent.

Evaluating safety and effectiveness of the early-onset sepsis calculator to reduce antibiotic exposure in Dutch at-risk newborns: a protocol for a cluster randomised controlled trial.

Introduction: Newborns are at risk for early-onset sepsis (EOS). In the Netherlands, EOS affects less than 0.2% of newborns, but approximately 5% are treated with empirical antibiotics.

Identification of the optimal treatment strategy for complex appendicitis in the paediatric population: a protocol for a multicentre prospective cohort study (CAPP study).

Introduction: In daily practice large heterogeneity in the treatment of children with complex appendicitis exists. Complex appendicitis can be divided into two subtypes; complex appendicitis with and without appendiceal mass and/or abscess. As complex appendicitis is associated with high morbidity and costs, identification of the optimal treatment strategy is essential.

Evaluation of low-dose aspirin in the prevention of recurrent spontaneous preterm labour (the APRIL study): A multicentre, randomised, double-blinded, placebo-controlled trial.

Background: Preterm birth is the leading cause of neonatal morbidity and mortality. The recurrence rate of spontaneous preterm birth is high, and additional preventive measures are required. Our objective was to assess the effectiveness of low-dose aspirin compared to placebo in the prevention of preterm birth in women with a previous spontaneous preterm birth.

Metatranscriptomic Analysis of Bacterial Communities on Laundered Textiles: A Pilot Case Study.

Microbially contaminated washing machines and mild laundering conditions facilitate the survival and growth of microorganisms on laundry, promoting undesired side effects such as malodor formation. Clearly, a deeper understanding of the functionality and hygienic relevance of the laundry microbiota necessitates the analysis of the microbial gene expression on textiles after washing, which-to the best of our knowledge-has not been performed before. In this pilot case study, we used single-end RNA sequencing to generate de novo transcriptomes of the bacterial communities remaining on polyester and cotton fabrics washed in a domestic washing machine in mild conditions and subsequently incubated under moist conditions for 72 h.

Cultivation-Based Quantification and Identification of Bacteria at Two Hygienic Key Sides of Domestic Washing Machines.

Detergent drawer and door seal represent important sites for microbial life in domestic washing machines. Interestingly, quantitative data on the microbial contamination of these sites is scarce. Here, 10 domestic washing machines were swab-sampled for subsequent bacterial cultivation at four different sampling sites: detergent drawer and detergent drawer chamber, as well as the top and bottom part of the rubber door seal.

Risk-Based Decision Making: A Systematic Scoping Review of Animal Models and a Pilot Study on the Effects of Sleep Deprivation in Rats.

Animals, including humans, frequently make decisions involving risk or uncertainty. Different strategies in these decisions can be advantageous depending the circumstances. Short sleep duration seems to be associated with more risky decisions in humans.

A multi-centre, randomized, non-inferiority trial to compare ulipristal with standard surgical treatment in women with symptomatic uterine fibroids: Protocol of the MYOMEX-2 trial.

Objectives: Fibroids are the most common benign tumours found in the uterus and can cause various symptoms. In 20-50 % of the women, an intervention is required. When conservative options fail, invasive options such as hysterectomy, uterine artery embolization or myomectomy are eligible options.

Influence of Sampling Site and other Environmental Factors on the Bacterial Community Composition of Domestic Washing Machines.

Modern, mainly sustainability-driven trends, such as low-temperature washing or bleach-free liquid detergents, facilitate microbial survival of the laundry processes. Favourable growth conditions like humidity, warmth and sufficient nutrients also contribute to microbial colonization of washing machines. Such colonization might lead to negatively perceived staining, corrosion of washing machine parts and surfaces, as well as machine and laundry malodour.

Goal attainment scaling as an outcome measure in rare disease trials: a conceptual proposal for validation.

Background: Goal Attainment Scaling (GAS) is an instrument that is intended to evaluate the effect of an intervention by assessing change in daily life activities on an individual basis. However, GAS has not been validated adequately in an RCT setting. In this paper we propose a conceptual validation plan of GAS in the setting of rare disease drug trials, and describe a hypothetical trial where GAS could be validated.

The patient's view on rare disease trial design - a qualitative study.

Background: Clinical trials in rare diseases are more challenging than trials in frequent diseases. Small numbers of eligible trial participants, often complicated by heterogeneity among rare disease patients, hamper the design and conduct of a 'classical' Randomized Controlled Trial. Therefore, novel designs are developed by statisticians.

Development of a standard form for assessing research grant applications from the perspective of patients.

Background: Health-research funding organizations are increasingly involving patient representatives in the assessment of grant applications. However, there is no consensus on an appropriate scope or definition of the patient perspective and the eligibility of potential patient reviewers to take on this role. The aim of our study is to develop a consensus-based template for patient reviewers to assess research grant applications from the patients' perspective.

11-Substituted Benzo[c]phenanthridines: New Structures and Insight into Their Mode of Antiproliferative Action.

The synthesis of various new structures of a library of 11-substituted 6-amino-11,12-dihydrobenzo[c]phenanthridines (BP) and 11-substituted 6-aminobenzo[c]phenanthridines (BP-D) is presented. These structures, further synthetic modifications, and the preparation of follow-up products which delivered about 40 new derivatives are described. Their potential as antiproliferative drug candidates was investigated by comparison of NCI 60 developmental therapeutics program (DTP) human tumor cell line screening data based on the results of in vitro tumor cell growth inhibition, including about 40 hitherto unpublished compound test results with up to 60 cancer cell lines.

Using patient experiences on Dutch social media to supervise health care services: exploratory study.

Background: Social media has become mainstream and a growing number of people use it to share health care-related experiences, for example on health care rating sites. These users' experiences and ratings on social media seem to be associated with quality of care. Therefore, information shared by citizens on social media could be of additional value for supervising the quality and safety of health care services by regulatory bodies, thereby stimulating participation by consumers.

Star-shaped poly(styrene)-block-poly(4-vinyl-N-methylpyridiniumiodide) for semipermanent antimicrobial coatings.

Goal of the present work is to develop an antimicrobial coating that can be applied from an aqueous solution and resists short washing cycles, but can be rinsed off by thorough washing. To this end, a series of star-shaped polystyrene-block-poly(4-vinyl-N-methylpyridinium iodide) polymers are synthesized by anionic polymerization using a core-first approach. The optimal resulting polymers are applied as coatings on glass slides, showing high antimicrobial efficiency against Staphylococcus aureus as well as Escherichia coli.

Proteome analysis of the farnesol-induced stress response in Aspergillus nidulans--The role of a putative dehydrin.

The isoprenoid alcohol farnesol represents a quorum-sensing molecule in pathogenic yeasts, but was also shown to inhibit the growth of many filamentous fungi. In order to gain a deeper insight into the antifungal activity of farnesol, we performed 2D-differential gel electrophoretic analysis (2D-DIGE) of Aspergillus nidulans exposed to farnesol. We observed an increased abundance of antioxidative enzymes and proteins involved in protein folding and the ubiquitin-mediated protein degradation.

The negative predictive value of breast Magnetic Resonance Imaging in noncalcified BIRADS 3 lesions.

Purpose: The purpose of this study is to determine whether breast MRI can provide a sufficient NPV to safely rule out malignancy in mammographic BIRADS 3 lesions.

Materials And Methods: In a 3-year consecutive mammographic examination study 176 out of 4391 patients had a lesion classified as BIRADS 3. 76 out of 176 patients underwent breast MRI as diagnostic work-up.

Evaluation of the virucidal performance of domestic laundry procedures.

Laundering is one of the most important means to ensure a sufficient hygiene standard in the household environment. To evaluate the performance of this process, it is desirable to have methods that mimic the real-life situation as closely as possible. Although methods for the evaluation of the antibacterial and antifungal efficacy of domestic laundry procedures are available, the effect of laundering on viruses is still rather unclear.
