Auditory filial imprinting induces quantitative changes of synaptic density in the forebrain area mediorostral neostriatum/hyperstriatum ventrale of the domestic chick. The aim of the present study was to examine the time window and the extent and quality of experience that is required for the induction of these synaptic changes. We found that a brief (30 min) experience with the imprinting situation (tone stimulus + mother surrogate) is sufficient to induce spine elimination, which is detectable on postnatal day 7, but not 80 min after the presentation of the imprinting stimuli. This synaptic reorganization requires the association of the acoustic imprinting tone with an emotional reward (mother surrogate); acoustic stimulation alone does not lead to detectable synaptic changes. The results of the present study provide further evidence that juvenile emotional learning events, such as filial imprinting, lead to a selective synaptic reorganization.

Background:The care process is often a complex and intimate process experienced by patients. Osteoarthritis (OA) care is usually characterised by multimodal interventions that consider the broader array of symptoms and functional limitations and often require a high level of patients’ compliance. Despite efforts to improve the quality of care of patients suffering from OA, and the publication of state-of-the-art clinical practice guidelines [1], the quality of the care process, as experienced by patients, seems to be suboptimal [2]. Hence, it is essential to investigate how patients experience this process to highlight potential elements that can enhance or spoil it to optimise the care quality.Objectives:To explore the patients’ experience of the received OA care process.Methods:Qualitative study, 10 semi-structured interviews were performed. The interview guide was created by a pool of healthcare professionals (physiotherapists, psychologists, nurses) and expert patients. It investigated the emotional experience, beliefs, expectations, perceived barriers and facilitators towards conservative treatments perceived by patients suffering from OA. The interviews lasted approximately one hour, were transcribed verbatim and analysed independently by two authors, who labelled their core parts to find categories and subcategories. A theme-based analysis was performed following an ecological paradigm, naturalistic epistemology, philosophy of phenomenological research.Results:Our analysis revealed 7 main categories with several subcategories (Fig. 1). 1) Uncertainty as some patients perceived treatment choice not to be based on medical evidence “there is an almost religious way of thinking on how to deal with the pathology. It is not an exact science when you choose the physicians you choose the treatment”. 2) Relationship with the self and the others as some patients did not feel understood or even shameful and hopeless about their condition. 3) Patients’ and Health Professionals’ beliefs about the pathology management where common thoughts were the perceived (ab)use of passive therapies, the movement as something dangerous and that OA is “something that you try to resist to, but (surgery) is your destiny”. 4) facilitators and 5) barriers of the adherence to therapeutic exercise that revolve around the cost of the therapy, the time needed and the willingness to change life habits. 6) Patients’ attitudes towards pathology in which the oldest patients perceive OA as “something I have to accept since I am getting old” and the youngest as “Something I have to fight”. 7) Relationship with food in which diet is seen as something that “you force yourself to follow” which is useful only to lose weight and not to preserve a high health status and where overeating is used “to eat your feelings”.Figure 1.Categories and Subcategories stemmed from the analysis of the patients’ interviewsConclusion:Patients suffering from hip and knee OA seem to experience an uncertain care process. The lack of clear explanations and the attitude towards conservative treatment, which is considered as “a pastime while waiting for surgery,” fosters the importance of providing patients with adequate information about the treatment, to shift their beliefs and improve their awareness. This will enhance a patient-centred and shared decision-making treatments.References:[1]Fernandes L, Hagen KB, Bijlsma JWJ, et al.

Abstract Background Patient-reported outcomes (PROs) are increasingly used to track symptoms and to assess disease activity, quality of life, and treatment effectiveness. It is therefore important to understand which PROs patients with rheumatic and musculoskeletal disease consider most important to track for disease management. Methods Adult US patients within the ArthritisPower registry with ankylosing spondylitis, fibromyalgia syndrome, osteoarthritis, osteoporosis, psoriatic arthritis, rheumatoid arthritis, and systemic lupus erythematosus were invited to select between 3 and 10 PRO symptom measures they felt were important to digitally track for their condition via the ArthritisPower app. Over the next 3 months, participants (pts) were given the option to continue tracking their previously selected measures or to remove/add measures at 3 subsequent monthly time points (month [m] 1, m2, m3). At m3, pts prioritized up to 5 measures. Measures were rank-ordered, summed, and weighted based on pts rating to produce a summary score for each PRO measure. Results Among pts who completed initial selection of PRO assessments at baseline (N = 253), 140 pts confirmed or changed PRO selections across m1–3 within the specified monthly time window (28 days ± 7). PROs ranked as most important for tracking were PROMIS Fatigue, Physical Function, Pain Intensity, Pain Interference, Duration of Morning Joint Stiffness, and Sleep Disturbance. Patient’s preferences regarding the importance of these PROs were stable over time. Conclusion The symptoms that rheumatology patients prioritized for longitudinal tracking using a smartphone app were fatigue, physical function, pain, and morning joint stiffness.

The functional value experience of family tourism has often been paid attention both by tourists themselves and the tourism industry, but the individual value experience of parents in family tourism has been neglected. Family tourism shifts the scenario of interpersonal interaction between families from home, the conventional environment, to a non-conventional one. This change in the interactive situation will inevitably bring about changes in interpersonal interaction behavior and individual perception, especially to tourists who take on the role of parents in a nuclear family. This study enriches the examination of the family tourism experience by exploring the interpersonal interaction, existential authenticity travel experiences, and quality of tourist experience perceived by parents in family tourism. The main findings are: 1) In the non-conventional environment of tourism, effective interaction between tourists and their families helps to improve tourists’ emotional experience and satisfaction; 2) Three aspects of existential authenticity are the internal causes of the impact of interpersonal interaction on emotional experience and satisfaction; 3) Differences in parental roles make important discrepancies between men and women’s perception of family tourism experiences. This study provides insights to understanding the family tourism market and brings valuable findings to the area of family tourism marketing and management.

Water ecosystems are constantly under the pressure of a high number of biotic and abiotic factors, and their action leads to the occurrence of fluctuations in species and populations. The specific response of organisms to external pressures leads to the reorganization of ecosystems, with qualitative and quantitative changes. The aim is to identify the microbial groups with the highest potential in the waste waters. Data were collected during 2015-16 in Bistrita. Identifying the bioindicators quality of microorganisms and their importance in ecosystems was done by comparing them with international databases. The use of microorganisms as bioindicators involves knowing the requirements for one or more environmental variables. The concept refers to the ability of microorganisms to accumulate pollutants. Flagellates are tolerant to acidity and react quickly and with sensitivity to environmental stress by inhibiting their movement. The multiplication of flagellates and filamentous bacteria is manifested through water disturbance and foam production.

Social interaction is an important way that we as humans connect with others. Socioemotional selectivity theory emphasizes the importance of close relationships, and Chinese culture attaches great importance to family members. As such, this study aimed to examine the differences in the quality of interactions that older Chinese adults have with close partners (e.g., children, friends, and relatives) as well as with other partners (e.g., neighbors, colleagues, and strangers) and to examine the association between interaction quality and emotional experience across these interactions. We collected data from 213 older adults over the course of 14 days. Results indicate that (1) compared to other partners, interactions with close partners are considered to be of higher quality; (2) in interactions with children and relatives, interaction quality is positively associated with positive affect (PA) and negatively associated with negative affect (NA); in interactions with friends and neighbors, interaction quality is only associated with PA; in interactions with colleagues and strangers, interaction quality is not associated with either PA or NA. Overall, interactions with close partners were shown to be considered to be of higher quality, and that the quality of interactions with family members was closely associated with emotional experience.

AbstractFor patients suffering from profound hearing loss or deafness still having respectable residual hearing in the low frequency range, the combination of a hearing aid with a cochlear implant results in the best quality of hearing perception (EAS – electric acoustic stimulation). In order to optimize EAS, ongoing research focusses on the integration of these stimuli in a single implant device. Within this study, the performance of piezoelectric actuators, particularly the dual actuator stimulation, in a scaled uncoiled test rig was investigated.
