Risk factors and protective factors in relation to subjective health among adult female victims of child sexual abuse

OBJECTIVE: To investigate the relationships between risk and protective factors and health outcome in a sample of adult females who had been victims of child sexual abuse. METHOD: Both person- and variable-oriented analyses were applied to questionnaire data from a non-clinical group of women (n = 152) reporting sexual abuse during childhood. RESULTS: Six groups with different patterns of risk and protective factors were found by cluster analysis. Two groups (Good Coping and Support Compensation) had significantly better health than expected in spite of severe abuse. Self-esteem and social support were strong predictors of health in the regression models. CONCLUSION: The relationships between risk and protective factors and health may be different in different groups of victims of child sexual abuse. Self-esteem was closely related to health outcome displaying the importance of this concept in clinical practice. Availability of resources seems to be more important for health outcomes than the amount of risk factors.     

Effect and feasibility of wearable physical activity trackers and pedometers for increasing physical activity and improving health outcomes in cancer survivors: A systematic review and meta-analysis

Purpose:This systematic review and meta-analysis aimed to evaluate the effect of wearable devices for improving physical activity and healthrelated outcomes in cancer survivors.Methods:CINAHL,Cochrane,Ebscohost,MEDLINE,Pubmed,ProQuest Health and Medical Complete,ProQuest Nursing and Allied Health Source,ScienceDirect,and SPORTDiscus databases were searched for randomized controlled trials published before September 1,2020,that evaluated interventions involving wearable devices in cancer survivors.Standardized mean differences(SMDs)were calculated to assess effects on physical activity and health-related outcomes.Subgroup analyses were conducted to assess whether the effects differed by interventions and cancer characteristics.Risk of bias was assessed using the Cochrane risk of bias tool.Results:Thirty-five trials were included(breast cancer,n=15,43%).Intervention durations ranged between 4 weeks and 1 year.Most trials(n=25,71%)involved pedometer-based physical activity interventions.Seven(20%)involved Fitbit-based interventions,and 3(9%)involved other wearable physical activity trackers(e.g.,Polar,Garmin).Compared to usual care,wearable devices had moderate-to-large effects(SMD range 0.54-0.87,p<0.001)on moderate-intensity physical activity,moderate-to-vigorous-intensity physical activity,total physical activity,and daily steps.Compared to usual care,those in the intervention had higher quality of life,aerobic fitness,physical function,and reduced fatigue(SMD range=0.18-0.66,all p<0.05).Conclusion:Wearable physical activity trackers and pedometers are effective tools that increase physical activity and improve health-related outcomes in individuals with cancer.Identifying how these devices can be implemented for longer-term use with other intervention components remains an area for future research.     

Degradation of lead-based pigments by salt solutions

Interactions of lead-based pigments with a number of inorganic salts, one of the most dangerous degradation agents of wall paintings, were studied under laboratory conditions. The results were used to interpret colour changes observed in 11th century frescoes from the church of Saint George in Kostoľany pod Tríbečom, the oldest preserved wall paintings in Slovakia. Interactions of selected pigments (lead white, massicot, red lead) with different salt solutions were performed within long-term laboratory experiments. We used a selection of naturally occurring salts (Na₂SO₄, MgSO₄, CaSO₄, NaCl, NaNO₃, Ca(NO₃)₂, Na₂CO₃, K₂CO₃ and urea) and, additionally, a range of synthetic salts that are often applied to the wall paintings during their cleaning and conservation (NaHCO₃, KHCO₃, (NH₄)₂CO₃, NH₄HCO₃). The reaction products were identified by X-ray powder diffraction. Red lead (Pb₃O₄) has a tendency to darken in all salt solutions containing dissolved atmospheric CO₂ due to disproportionation to plattnerite (PbO₂) and cerussite (PbCO₃). Massicot (PbO) in a wet state reacts with atmospheric CO₂ to form hydrocerussite and finally cerussite. Lead white (PbCO₃ and Pb₂CO₃(OH)₂) reacts with sulphates, carbonates and chlorides to form their respective salts in high yield and, sometimes, without any apparent colour change. Samples taken from the dark brown parts of the wall paintings in Saint George's church were analysed using laboratory X-ray powder microdiffraction. The presence of hydrocerussite, cerussite, plattnerite and lead magnesium carbonate was revealed. According to the results of laboratory experiments, the original lead-based pigment of the now darkened parts was red lead.     

A Way of Visualising Children's and Young People's Thoughts about the Environment: A study of drawings

This article attempts to visualise the way in which children and young people think about a specific topic, namely the environment. The aim is to make the thinking of children and young people available and to interpret the meaning of their thoughts about our environment. The theoretical roots of the study are to be found within the phenomenology of the lifeworld. The study is based on empirical material consisting of drawings produced by 109 children and young people, combined with subsequent oral comments. During the drawing analysis different structures and patterns gradually crystallised, and eventually four different themes emerged, consisting of thoughts which focus on the following: the good world, the bad world, the dialectics between the good and the bad world, and symbols and actions protecting the environment. It can be stated that the results which emerged, in the form of the thoughts of the children and young people on the environment, reflect a thinking characterisedby many nuances, such as clean and unspoilt nature in different manifestations, the need for human beings to use nature for recreation and well-being, environmental destruction in different forms, and direct or indirect ways of taking care of the prevailing environmental situation.     

Implementing vision research in special needs education

This article presents experiences from vision research implemented in education and argues for the need for teachers with visual competence and insight into suitable methods for stimulation and learning. A new type of continuing professional development (CPD) focuses on the role of vision in children's learning and development, the consequences of frequently occurring vision disturbances and related new educational possibilities. Participating teachers undertake a period of practical teaching training in their home community. Two students' cases visualise the need to break out of the narrow definition of visual impairment and become capable of evaluating the visual challenges affecting many pupils and their learning. The two cases presented represent various issues of visual challenges; both reached a better functional level, including better reading, following improved vision after the educational interventions. These results illustrate that vision competence in schools is most useful and ought to be widely accessible.
