t to distinguish between them. The differential diagnosis of mesothelioma should therefore include claudin-5 in a panel of immunohistochemical markers to distinguish mesothelioma from angiosarcoma.Increased attention to links between walking, health and wellbeing have contributed to a growth in the number of walking groups meeting on a regular basis to offer short, social walks. Walking group interventions are known to increase physical activity and to have wide-ranging health benefits, and there is evidence that drop out is generally low. The aim of this paper is to synthesise qualitative research on experiences and perceptions of group walking in order to develop a new conceptual understanding of the group walking experience. We conducted a systematic search of the literature and identified 22 such studies which we synthesised using meta-ethnography. Included studies were conducted in the UK, USA, Australia and Ireland. Most reported research was undertaken with outdoor walking groups, some of which catered specifically for people who shared a disease experience or a disability. A smaller number of studies examined indoor mall walking groups, while two looked at perceptions of non-participants of group walking as a potential activity. From the original constructs identified in the papers we derived five higher order constructs seeking and enjoying health and fitness, attachment to walking, providing purpose and confidence, mobile companionship and a peaceful and contemplative shared respite from everyday life. Doxycycline We argue that participating in a walking group provides a set of experiences that together constitute a specific form of shared or communal therapeutic mobility that is not simply the accumulation of the constructs we have outlined. Rather, we suggest that an initial instrumental and disciplinary focus on health and fitness is transformed through the experience of group walking into a shared meaningful and enjoyable practice; an emergent communal therapeutic mobility, which recruits and retains large numbers of group walkers. However, this communal therapeutic mobility is not equally accessible to all.

Patients who have multiple chronic conditions (MCCs) and their informal caregivers experience poorer health-related quality of life (HRQOL). Perceived social support has been shown to influence HRQOL.

This study aimed at identifying the differences between patients' and caregivers' physical and mental HRQOL; and determining the association between their perception of social support from different sources, and their own and their dyad partner's HRQOL.

Patients with MCCs and their caregivers (345 dyads) were enrolled in a multicenter cross-sectional study conducted in Italy. The Multidimensional Scale of Perceived Social Support measured perceived social support from family, friends, and significant others, and the 12-Item Short-Form Health Survey measured the physical and mental component of HRQOL in dyads. The dyadic analysis was conducted using the Actor-Partner Interdependence Model through structural equation modelling.

Family support perceived by each member of the dyad was associated positively w maintenance and enhancing of this support.Despite the growing attention being paid to teaching mathematics for students with disabilities, the existing research tends to focus on mathematical skill acquisition, but not on skill maintenance. The researchers in this study reviewed all studies from 1975 to 2018 that involved teaching mathematics to individuals with intellectual disability. A total of 135 studies met inclusion criteria, but only 53 studies involved a maintenance phase (39.2%). Among the 53 studies, only 22 were included for the final analysis, after evaluating their methodological rigor. In those 22 studies, there was no consensus among researchers on the standards for conducting a maintenance phase (i.e., latency between intervention and maintenance phases, length of maintenance phase, number of maintenance sessions). Further, in the studies which included a maintenance phase, the most widely taught mathematical content was numbers and operations. All studies employed intervention packages which included more than one instructional method and/or materials and the most widely used instructional method was prompting while the most widely used instructional materials were visual supports and manipulatives. The results suggest that prompting is an evidence-based practice for individuals with intellectual disability in supporting maintenance, while explicit instruction, time delay, feedback, and instructional sequence (e.g., the virtual-representational-abstract instructional sequence) are potentially evidence-based practice for individuals with intellectual disability.Behaviour of radionuclides released into environment is crucial for further evaluation of any kind of possible effects. Possibility of observation how does a radionuclide behave in natural environment is limited to very few post accidental areas. However, valuable observation can be collected at areas where enhanced concentration of natural radionuclides is presented caused by activity of non-nuclear industry. One example is area affected by release of radium rich brines from coal mines (Upper Silesia, south of Poland) that let one observe radium and its decay product behaviour in freshwater ecosystem from long-term perspective. Selected as long-term observatory site former mine water reservoir allowed identification of processes leading to accumulation of radium in bottom sediments and observation of its further behaviour from 17-years-time perspective. New data were collected during two-years monitoring campaign and compared with archive data on radioactivity in water and sediments collected in 1999. Radium-barium co-precipitation process was identified as main source of sediments heavy contamination, however, radium chemical form resulted from this process is insoluble and not easy migrate to other environmental compartments, what was proved by low 226Ra and 210Pb transfer to water measured under laboratory condition and to biota observed on site. As barium is not always present in mine radium rich brines a discussion is launched what would happen when such waters are released into environment based on simple laboratory experiment. In main conclusion is underlined that the current radium activity concentration in sediments is lower than expected only considering radioactive decay. Distribution of 226Ra, 228Ra and 210Pb in sediment profiles suggest that bio- or mechanical turbation (e.g. local flood) is responsible for significant 226Ra deficiency observed.
