Evaluation of Breast Skin/Nipple-Areolar Complex Sensation and Quality of Life after Nipple-Sparing Mastectomy Followed by Reconstruction.

: Sensation of the breast skin and nipple-areolar complex (NAC) is commonly assumed to be diminished or completely absent following nipple-sparing mastectomy (NSM) with implant- or expander-based reconstruction. The purpose of this cohort study was to evaluate breast skin and NAC long-term touch pressure sensibility, from 1 month to 1 year, after NSM followed by reconstruction with an implant or expander, and patient quality of life (QoL), hypothesizing that sensibility may diminish with a small progressive return throughout the postoperative period. : This was achieved by performing sensation tests using Semmes-Weinstein monofilaments (SWM) in nine predefined points of the breast and NAC, a two-point discrimination test (TPD) in the four quadrants of the breast, and QoL assessment using the BREAST-Q.

Novel Nipple Reinnervation Technique Using N. Suralis Graft.

Following nipple-sparing mastectomy (NSM), patients commonly experience significant impairment or total loss of nipple sensitivity, which negatively impacts the patients' quality of life, whereas patients who retain nipple sensation postoperatively experience enhanced physical, psychosocial, and sexual well-being. Reinnervation techniques such as nerve allografting have been utilized to retain sensation. Despite the benefits of nerve allografts, such as lack of donor site morbidity, ease of use, and potentially shorter surgery time, there are shortcomings, such as the cost of commercially available acellular nerve allografts, and, most importantly, decreased sensory and motor function recovery for acellular nerve allografts with a diameter greater than 3 mm or a length greater than 50 mm.

IT/QA and Regulatory Aspects of Digital Pathology: Results of the 8th ESTP International Workshop.

Digital toxicologic histopathology has been broadly adopted in preclinical compound development for informal consultation and peer review. There is now increased interest in implementing the technology for good laboratory practice-regulated study evaluations. However, the implementation is not straightforward because systems and work processes require qualification and validation, with consideration also given to security.

Introduction to the EQIPD quality system.

While high risk of failure is an inherent part of developing innovative therapies, it can be reduced by adherence to evidence-based rigorous research practices. Supported through the European Union's Innovative Medicines Initiative, the EQIPD consortium has developed a novel preclinical research quality system that can be applied in both public and private sectors and is free for anyone to use. The EQIPD Quality System was designed to be suited to boost innovation by ensuring the generation of robust and reliable preclinical data while being lean, effective and not becoming a burden that could negatively impact the freedom to explore scientific questions.

Defining polypharmacy: in search of a more comprehensive determination method applied in a tertiary psychiatric hospital.

Aims: This cross-sectional pharmacoepidemiologic study examined the prevalence of polypharmacy and psychotropic polypharmacy among inpatients in a tertiary psychiatric hospital in Belgium.

Methods: Current prescriptions of all inpatients suffering from mental disorders were extracted from the hospital Computerized Physician Order Entry. Two methods were used to examine definitive polypharmacy (defined as the concomitant use of at least five medicines): number of medicines per active component and per prescription.

Quality Governance in Biomedical Research.

Quality research data are essential for quality decision-making and thus for unlocking true innovation potential to ultimately help address unmet medical needs.The factors influencing quality are diverse. They depend on institution type and experiment type and can be of both technical and cultural nature.

Body mass index and nipple preservation are major contributors to satisfaction and aesthetic outcome rates after implant-based immediate breast reconstruction.

Introduction: Immediate breast reconstructions (IBR) have become an integral part of modern breast cancer management. However, in a small breast unit the spectrum of methods used for IBR could be limited, which could result in poorer results in some cases. The aim of the study is to evaluate the patient satisfaction and aesthetic outcome results in a breast unit where only implant-based IBR were performed.

Evidence that Ralstonia eutropha (Alcaligenes eutrophus) contains a functional homologue of the Ralstonia solanacearum Phc cell density sensing system.

In the phytopathogen Ralstonia (Pseudomonas) solanacearum, control of many virulence genes is partly mediated by the Phc cell density sensing system. Phc uses a novel self-produced signal molecule [3-hydroxypalmitic acid methyl ester (3-OH PAME)], an atypical two-component system (PhcS/PhcR), and a LysR-type activator (PhcA) to regulate a reversible switching between two different physiological states. While Phc is present in most R.

Effect of the siderophore alcaligin E on the bioavailability of Cd to Alcaligenes eutrophus CH34.

Alcaligin E, the siderophore of the heavy metal-resistant A. eutrophus strain CH34, was shown to interact with Cd and consequently affect its bioavailability and toxicity. The addition of alcaligin E markedly stimulated the growth in the presence of Cd of an alcaligin E-deficient CH34 derivative.

Siderophore-mediated iron uptake in Alcaligenes eutrophus CH34 and identification of aleB encoding the ferric iron-alcaligin E receptor.

Siderophore production in response to iron limitation was observed in Alcaligenes eutrophus CH34, and the corresponding siderophore was named alcaligin E. Alcaligin E was characterized as a phenolate-type siderophore containing neither catecholate nor hydroxamate groups. Alcaligin E promoted the growth of siderophore-deficient A.
