BACKGROUND: Low disease activity is a validated target of current systemic lupus erythematosus (SLE) therapy. The aim of this study was to assess the ability of belimumab to achieve low disease activity states in real-life settings. METHODS: Multicentre prospective observational study of consecutive SLE patients receiving belimumab for at least 3 months, due to active disease refractory to at least one conventional immunosuppressant. Disease activity, including the recently defined lupus low disease activity state (LLDAS) and remission (clinical SLEDAI-2K = 0), accrual of organ damage, flares and side effects were documented...

Trochulus hispidus and T. sericeus are hairy snails widely distributed in Europe. They differ in shell morphology and are usually found in various land habitats. However, their morphology does not match genetic distance as they do not form distinct clades. Therefore, it is interesting to determine to what extent environmental factors can control their phenotypes. We analysed the morphological traits and many environmental features of their habitats to find relationships between these parameters and explain ecological reasons for this plasticity...

OBJECTIVES: Electrocochleography is increasingly being utilized as an intraoperative monitor of cochlear function during cochlear implantation (CI). Intracochlear recordings from the advancing electrode can be obtained through the device by on-board capabilities. However, such recordings may not be ideal as a monitor because the recording electrode moves in relation to the neural and hair cell generators producing the responses. The purposes of this study were to compare two extracochlear recording locations in terms of signal strength and feasibility as intraoperative monitoring sites and to characterize changes in cochlear physiology during CI insertion...

PURPOSE: Alopecia is one of the most distressing side effects of chemotherapy. Evaluating and comparing the efficacy of potential therapies to prevent chemotherapy-induced alopecia (CIA) has been complicated by the lack of a standardized measurement for hair loss. In this study we investigated the correlation between patient-reported outcome assessments and quantitative measurement with the hair check to assess CIA in clinical practice. METHOD: Scalp cooling efficacy was evaluated by patients by World Health Organisation (WHO) of CIA, Visual Analogue Scale (VAS) and wig use...

Androgenetic alopecia (AGA) is a dermatological disorder of scalp hair loss characterized by a progressive miniaturization of hair follicles with shortened anagen phase leading to a decreased number of hairs on the scalp. It is a complex polygenic trait prevailing around two-thirds of the male population. Elevated expressions of 5α-dihydrotestosterone and androgen receptor are the causal factors for AGA. This review describes recent studies on the role of androgens and androgen receptor (AR) transactivation activity in modulating the Wnt/β-catenin signaling in the dermal papilla cells of the balding scalp in androgenetic alopecia...

BACKGROUND: In the cochlea, auditory development depends on precise patterns of innervation by afferent and efferent nerve fibers, as well as a stereotyped arrangement of hair and supporting cells. NrCAM is a homophilic cell adhesion molecule that controls diverse aspects of nervous system development, but the function of NrCAM in cochlear development is not well understood. RESULTS: Throughout cochlear innervation, NrCAM is detectable on spiral ganglion neuron (SGN) afferent and olivocochlear efferent fibers, and on the membranes of developing hair and supporting cells...

Transmembrane proteins that mediate the cellular uptake or efflux of thyroid hormone potentially provide a key level of control over neurodevelopment. In humans, defects in one such protein, solute carrier SLC16A2 (MCT8) are associated with psychomotor retardation. Other proteins that transport the active form of thyroid hormone triiodothyronine (T3) or its precursor thyroxine (T4) have been identified in vitro but the wider significance of such transporters in vivo is unclear. The development of the auditory system requires thyroid hormone and the cochlea is a primary target tissue...

BACKGROUND: Noise-induced hearing loss (NIHL) is the most prevalent form of acquired hearing loss and affects about 40 million US adults. Among the suggested therapeutics tested in rodents, suberoylanilide hydroxamic acid (SAHA) has been shown to be otoprotective from NIHL; however, these results were limited to male mice. METHODS: Here we tested the effect of SAHA on the hearing of 10-week-old B6CBAF1/J mice of both sexes, which were exposed to 2 h of octave-band noise (101 dB SPL centered at 11...

The purpose of this study was to investigate whether or not the concentration levels of certain kinds of trace elements in hair are associated with periodontitis. We studied a total of 109 participants, which are composed of 25 participants with periodontitis and 84 participants without periodontitis. Periodontal conditions were assessed by measuring the periodontal clinical attachment loss and pocket depth, which were determined at six sites of all teeth. Periodontitis was defined according to the criteria of periodontitis proposed by CDC-AAP...

BACKGROUND: Rodent studies indicate that noise exposure can cause permanent damage to synapses between inner hair cells and high-threshold auditory nerve fibers, without permanently altering threshold sensitivity. These demonstrations of what is commonly known as hidden hearing loss have been confirmed in several rodent species, but the implications for human hearing are unclear. OBJECTIVE: Our Medical Research Council-funded program aims to address this unanswered question, by investigating functional consequences of the damage to the human peripheral and central auditory nervous system that results from cumulative lifetime noise exposure...

A 62-year-old Hispanic woman, a resident of Puerto Rico, presented with symptoms of chronic cough and shortness of breath for the past 2 years that were slowly and progressively getting worse. She received a diagnosis of asthma on the basis of her history of symptomatic "wheezing" and had been on treatment with inhaled bronchodilators and corticosteroids with minimal symptomatic improvement. The peculiarity of her symptoms was that her dyspnea was worse when she was reclining in bed and she would often hear a "whistling" noise in her throat during those times...

BACKGROUND: Androgenetic alopecia (AGA) is the most common type of hair loss in both males as well as females, occurring in up to 57% of women by the age of 80 years. Androgenetic alopecia is associated with a high psychological burden and often results in substantially reduced quality of life, poor body image and low self-esteem, particularly in women. Caffeine-based products have shown promise, both in vitro and in vivo, as potential treatments for AGA. This study was performed to determine the efficacy of a phyto-caffeine- containing shampoo used over a 6-month period in female subjects with AGA...

Purpose: Trastuzumab, a humanized anti-human epidermal growth factor receptor 2 (anti-HER2) antibody delivered intravenously, has revolutionized the treatment of patients with breast cancer overexpressing HER2 protein. Recently, a newer subcutaneous formulation was shown to have comparable efficacy to the initial intravenous trastuzumab. In this study, we aimed to evaluate the impact of subcutaneous trastuzumab on the health-related quality of life (HRQoL) of patients diagnosed with early or metastatic HER2-overexpressing breast cancer...

Drug delivery to the inner ear by nanomedicine strategies has emerged as an effective therapeutic approach for the management of inner ear diseases including hearing and balance disorders. It is well accepted that substance enters the perilymph from the middle ear through the round window membrane (RWM), but the passage through the oval window (OW) has long been neglected. Up to now, researchers still know little about the pathway via which nanoparticles (NPs) enter the inner ear or how they reach the inner ear following local applications...
