Published: December 2018

Background:
The health benefits of regular physical activity and exercise have been widely acknowledged. Yet physical inactivity remains an issue in South Africa. This study examines factors associated with physical activity amongst South Africans.

Methods:
This analysis used the 2012 nationally representative population-based household survey conducted using a multi-stage stratified cluster sampling design. Multinomial bivariate and multiple logistic regression models were used to determine whether physical activity is significantly influenced by socio-demographic and lifestyle related characteristics.

Results:
Out of 26339 individuals, 57.4 % (CI: 55.9-59) were not physically active, 14.8 % (CI: 13.6-16) were moderately physically active, and 27.8 % (CI: 26.6-29.1) were vigorously physically active. Relative to those who reported physical inactivity, having higher education and being of a higher socioeconomic status increased the likelihood of engaging in moderate physical activity. Increasing age, being female, and living in informal settlements decreased the likelihood of engaging in moderate physical activity. Increasing age, being female, being married, being from rural formal settlements, and having poorer self-rated health reduced the likelihood of engaging in vigorous physical activity.

Conclusion:
The findings suggest that there is a need for health promotion efforts targeting particular groups from selected socio-demographic strata including unhealthy individuals and those from disadvantaged communities.

Published: December 2018

Background and objectives
The absence of accepted patient-centered outcomes in research can limit shared decision-making in peritoneal dialysis (PD), particularly because PD-related treatments can be associated with mortality, technique failure, and complications that can impair quality of life. We aimed to identify patient and caregiver priorities for outcomes in PD, and to describe the reasons for their choices.

Design, setting, participants, & measurements
Patients on PD and their caregivers were purposively sampled from nine dialysis units across Australia, the United States, and Hong Kong. Using nominal group technique, participants identified and ranked outcomes, and discussed the reasons for their choices. An importance score (scale 0–1) was calculated for each outcome. Qualitative data were analyzed thematically.

Results
Across 14 groups, 126 participants (81 patients, 45 caregivers), aged 18–84 (mean 54, SD 15) years, identified 56 outcomes. The ten highest ranked outcomes were PD infection (importance score, 0.27), mortality (0.25), fatigue (0.25), flexibility with time (0.18), BP (0.17), PD failure (0.16), ability to travel (0.15), sleep (0.14), ability to work (0.14), and effect on family (0.12). Mortality was ranked first in Australia, second in Hong Kong, and 15th in the United States. The five themes were serious and cascading consequences on health, current and impending relevance, maintaining role and social functioning, requiring constant vigilance, and beyond control and responsibility.

Conclusions
For patients on PD and their caregivers, PD-related infection, mortality, and fatigue were of highest priority, and were focused on health, maintaining lifestyle, and self-management. Reporting these patient-centered outcomes may enhance the relevance of research to inform shared decision-making.

Abstract
OBJECTIVE To investigate caregiver burden and its potential associations with psychosocial function and veterinary service use among dog and cat owners and with factors related to treatment plan adherence among owners of animals with chronic or terminal disease.
DESIGN Cross-sectional, observational study.
SAMPLE 124 clients of a small animal hospital.
PROCEDURES Study participants were recruited by email. Owners of sick animals were blindly matched with owners of healthy animals (62/group) by age, gender, and companion animal species. Respondents completed electronic questionnaires related to demographics and previously described measures of caregiver burden, psychosocial function, and treatment plan adherence. Veterinary medical records were reviewed to verify animal health status and assess veterinary service use (billable and nonbillable contacts with veterinary staff) in the 12 months prior to study enrollment. Variables were tested for association by statistical methods.
RESULTS Questionnaire scores reflected greater caregiver burden; greater symptoms of depression, anxiety, and stress; and poorer quality of life for respondents with sick animals than for respondents with healthy animals. Greater caregiver burden was associated with scores reflecting poorer psychosocial function and with greater veterinary service use. The number of nonbillable, but not billable, contacts was greater for respondents with high caregiver burden than for those without this finding. Treatment plan factors associated with greater caregiver burden included changes in routine because of the animal's condition and perception that following new rules and routines for management of the condition was challenging.
CONCLUSIONS AND CLINICAL RELEVANCE Awareness of potential caregiver burden and psychosocial distress in clients with sick companion animals may help veterinarians identify opportunities for an empathic response. Future research should assess directionality of the relationship between these factors.
Quantum chemical study of electron structure and charge transport properties of symmetric acenequinones

Published: December 2018

Abstract
A systematic theoretical study using density functional theory is presented to estimate the structural, electronic, and charge-transfer characteristics of a symmetric fluorination of acenequinones outer rings. The change in aromaticity of model derivatives was described by different types of aromaticity indices. By considering a hopping mechanism and using the Marcus theory in combination with the Einstein-Smoluchowski relation, electronic drift mobilities were predicted for selected dimer configurations obtained from X-ray structures of anthraquinone, 6,13-pentacenequinone and its octafluorinated derivatives. The analysis of obtained data showed that the fluorination of the outer rings of acenequinones can lower the energy of the lowest unoccupied molecular orbital to the range from −3.0 to −4.0 eV, i.e. typical for organic n-type semiconducting materials. Finally, potential electric semiconductivity of available X-ray structures relating to drift mobilities was discussed.
The design and NMR structure determination of yttrium-oligopeptide tags for recombinant proteins and antibodies
Authors: Múdra Marcela , Breza Martin , Lintnerová Lucia , Filo Juraj , Bauer Jacob 
Published: December 2018

Abstract
A strategy for the design of new yttrium(III) tags consisting of sequences of naturally occurring amino acids is described. These tags are 4–6 amino acids in length and consist of aspartic and glutamic acids. The use of natural amino acids would allow these oligopeptides to be incorporated into recombinant proteins at the DNA level, enabling the protein to be Y(III)-labelled after protein isolation. This allows a radionuclide or heavy atom to be associated with the protein without the necessity of further synthetic modification. Suitable peptides able to chelate Y(III) in stable complexes were designed based on quantum-chemical calculations. The stability of complexes formed by these peptides was tested by isothermal titration calorimetry, giving dissociation constants in the micromolar range. The likely structure of the most tightly bound complex was inferred from a combination of NMR experiments and quantum-chemical calculations. This structure will serve as the basis for future optimizations.

Authors: Nikolova M. G. , Penkov A. B. , Boyanov M. A. 
Published: December 2018

Abstract
Obesity has been linked with vitamin D deficiency in a number of cross-sectional studies, reviews and meta-analyses. The aim of the present study was to assess the correlations of plasma 25(OH) vitamin D levels with indices of body composition examined by DXA with an emphasis on lean and bone mass as well as on indices such as android/gynoid fat, appendicular lean mass, fat-mass indexes (FMI) and fat-free mass indexes (FFMI). 62 adult subjects consented to participate – 27 men (43.5%) and 35 women (56.5%). Their mean age was 45.3 ± 9.5 years. Fan-beam dual-energy X-ray (DXA) body composition analysis was performed on a Lunar Prodigy Pro bone densitometer with software version 12.30. Vitamin D was measured by electro-hemi-luminescent detection as 25(OH) D Total (ECLIA, Elecsys 2010 analyzer, Roche Diagnostics). Statistical analyses were done using the SPSS 23.0 statistical package. The serum 25(OH)D level was correlated significantly only to the whole body bone mineral content, the appendicular lean mass index (ALMI) and the ALM-to-BMI index, underlining a predominant role for lean and fat-free mass. Vitamin D showed a very weak correlation to % Body Fat and the Fat Mass Index (FMI) in men only. Moreover, the multiple regression equation including the associated parameters could explain only 7% of the variation in the serum 25(OH) D levels. Our conclusion was, that there are differences in the associations of the vitamin D levels with the different body composition indices, but these associations are generally very weak and therefore – negligible.

Published: December 2018

Abstract
Hairline is a crucial landmark in facial aesthetics. Its restoration in terms of position, continuity and hair growth is of a paramount importance in facial plastic aesthetic and reconstructive surgery. The purpose of the paper is to demonstrate the effectiveness of using local tissue only in the restoration of skin and soft tissue defects affecting the hair-line. A brief retrospective analysis of clinical cases with defects engaging the hairline was made. The majority of the patients (20 out of 22) were operated because of skin lesions of different entities. In 7 of the cases the direct closure technique was applied as a surgical tool for hairline restoration and in 15 of them rotational flaps were the best reconstructive option. A special emphasis is put on the defect size in regards of choosing the right surgical technique for defect closure in order to achieve the best aesthetic outcome in the hairline restoration.

Abstract
Congenital lacrimal fistula is a developmental abnormality. This is a case of a patient with an external congenital lacrimal sac fistula. Surgical treatment was used to correct the condition. Immediate postoperative results were seen. To present a case of a patient with an external congenital lacrimal sac fistula, in which surgical treatment was applied and immediate postoperative results with a good outcome were seen. A 3-year-old boy with an external congenital lacrimal sac fistula presented to our clinic. The skin orifice was observed on the left eye in a typical place – located in the inferomedial aspect of the medial canthal angle. The patient was treated in the at the Eye clinic, at university hospital “Dr. Georgi Stranski” – Pleven, Bulgaria. He underwent a surgical procedure – simple fistula excision (closed fistula excision). The surgical technique was a successful closed fistula excision. In the immediate postoperative period there were no complications such as infection, recurrence or worsening of the epiphora, poor cosmetic results, bleeding or damage to the lid structures or nose. The prognosis for patients with congenital lacrimal fistulas is quite good. Many are asymptomatic and those who have symptomatic epiphora or mucoid discharge can be successfully treated by surgery. Several surgical options exist – closed fistula excision, dacryocystorhinostomy (DCR) with fistula excision and fistula excision with nasolacrimal intubation. Symptomatic congenital lacrimal sac fistulas can be treated successfully with excision alone.
The effect of a water dam on Lake Powidzkie and its vicinity
Authors: Nowak Bogumił Michał , Ptak Mariusz 
Published: December 2018

Abstract
The paper presents an attempt to assess the effect of damming of lakes on water resources, based on the example of Lake Powidzkie (Central Poland) and its catchment. The region in which the analysed object is located has the greatest water deficits in Poland. The co-occurrence of unfavourable natural and anthropogenic factors contributed to a considerable reduction in the water resources retained in the lake. Particularly low water levels were recorded in the 1990s and in the first decade of the 21st century. The situation was not improved by a water dam constructed on the out-flow from the lake in the 1960s, due, among other things, to neglect in its exploitation. With regard to the modernisation of the dam in 2010 and the favourable hydrological situation in the winter of 2011, it was possible to retain the excess water and substantially reduce its outflow. The restoration of the lost water resources, and the hydrological benefits of this were still observable several years later. Problems related to water deficits are becoming increasingly common in many regions of the world. One solution to mitigate such a situation may be, among others, to dam natural lakes. This is simpler, cheaper, and less invasive for the environment than the construction of new water reservoirs.
Water temperature in the lakes of Northern Poland during the bathing season
Authors: Skowron Rajmund 
Published: December 2018

Abstract
The study presents characteristics of the bathing season on the basis of stationary daily measurements of surface water temperature in the lakes in the period 1971-2015 conducted by the Institute of Meteorology and Water Management. These measurements were taken in the littoral zone (from bridges) of 28 lakes at 7:00 (6:00 GMT). In order to determine representativeness of these measurements, the author also documents the comparison of water temperature with its values at various points of the lake and its daily course. Stationary surface water temperature measurements provided the basis for the characteristics of the average, the earliest and the latest dates of the beginning and end of the bathing seasons, their duration and mean water temperatures in the summer months. Hence, a new parameter (tsum) is introduced to define the mean surface water temperature for the summer months (June, July and August), and compare water temperature in lakes over a larger area (the Baltic Sea catchment area). The most favorable conditions for bathing in Polish lakes are found in the western part of the Wielkopolskie Lakeland (lakelands: Łagowskie, Poznańskie, Sławskie) from the beginning of July to the end of August, when the surface water temperature in lakes generally exceeds 18°C. Furthermore, the best conditions for bathing in the water are from 10:00 to 18:00. When choosing a place to relax, holidaymakers should also consider bathing locations, infrastructure and safety conditions.
Analysis of air mass back trajectories with present and historical volcanic activity and anthropogenic compounds to infer pollution sources in the South Shetland Islands (Antarctica)
Authors: Szumińska Danuta , Czapiewski Sebastian , Szopińska Małgorzata , Polkowska Żaneta 
Published: December 2018

Abstract
This work analyses atmospheric transport of natural and anthropogenic pollution to the South Shetland Islands (SSI), with particular reference to the period September 2015 – August 2017. Based on data from the Global Volcanism Program database and air mass back trajectories calculated using the HySPLIT model, it was found that it is possible that in the analysed period volcanic pollution was supplied via long-range transport from South America, and from the South Sandwich Islands. Air masses flowed in over the South Shetland Islands from the South America region relatively frequently – 226 times during the study period, which suggests the additional possibility of anthropogenic pollution being supplied by this means. In certain cases the trajectories also indicated the possibility of atmospheric transport from the New Zealand region, and even from the south-eastern coast of Australia. The analysis of the obtained results is compared against the background of research by other authors. This is done to indicate that research into the origin of chemical compounds in the Antarctic environment should take into account the possible influx of pollutants from remote areas during the sampling period, as well as the possible reemission of compounds accumulated in snow and ice.

Authors: Greenberg Desire , Rogerson Jayne M. 
Published: December 2018

Abstract
In recent years several new forms of lodging have developed as alternatives to the hotel. For business travellers the serviced apartment has emerged as a new phenomenon. Within extant accommodation scholarship the service apartment sector has attracted minimal international attention either from tourism or property researchers. This paper analyses the development and character of service apartments in one of South Africa’s major business tourism destinations, the city of Cape Town. It is disclosed that serviced apartments are clustered around different business nodes in the city and spatially differentiated in terms of serving distinctive business traveller markets.

Published: December 2018

AbstractClimate and weather are important resources for tourism. In particular, nature-based tourism activities and operations are largely dependent on and affected by environmental conditions and changes. Due to the significant socio-economic role of the nature-based tourism and the tourism industry, in general, in the region of southern Africa it is important to understand the dynamics between the industry and climate change. A key aspect of this understanding are perceptions and adaptation preparedness of tourism operators towards the estimated impact of climate change. There is a dearth of empirical studies on climate change perceptions and adaptation in nature-based tourism operations across southern Africa and specifically from Zimbabwe. This research gap is addressed in this article which provides an exploratory analysis of the nature of climate change adaptation practices occurring in southern Africa using evidence from Hwange National Park, Zimbabwe.

Published: December 2018

Abstract
Numerous specialist studies allow managers to find accessible answers on how to develop and increase the autonomy of educational establishments in the type of management model. Every school head has to have a clear vision of the school and of its connection with the society it is part of. The vision of the manager must be shared with both the institution’s staff and the local community. It should be pointed out that there is no effective school if the manager can’t express this vision with the rest of the people who come into contact with the unit. Vision is the starting point for a mission assigned to the school unit by its manager. In general, the mission of the school is to integrate each pupil in society, to continually improve the performance of the educational act in good conditions and to the required standards. The purpose of this article is to outline the new challenges of the modern world and to highlight effective management methods.
