Purpose: The aim of this paper is to discuss exposure to stress and the incidence of occupational burnout among oncology nurses.
Methods: To study the discussed issue, we analyzed six full-text research papers which were searchable by EBSCO and met all required criteria (words included in the abstract, English publication, size of the study group).
Results: Exposure to chronic occupational stress may lead to developing burnout syndrome. Social service professionals are especially affected as they are expected to be emotionally engaged in their jobs, which particularly applies to such health care professionals as nurses, psychologists, police officers and social workers. Because of occupational burnout work efficiency may deteriorate. Oncology nurses are among the most affected nurse groups in terms of exposure to the risk of burnout.
Conclusions: Oncology nurses as well as other oncology workers exhibit an increased risk and a higher grade of burnout. Psychological training sessions are available which effectively prevent and alleviate the effects of burnout.
Charnockites – i.e., orthopyroxene-bearing felsic rocks – were formed in a deep-seated dry environment, either under plutonic or high-grade metamorphic conditions. Most charnockites known from the crystalline basement of Poland appear to be of Mesoproterozoic age (1.50–1.54 Ga), cogenetic with the Suwałki Anorthosite Massif, and associated with mangerite and granite members forming the AMCG suite of the Mazury Complex. Genetically distinct rocks, characterised by the presence of anhydrous minerals, e.g., orthopyroxene and garnet, were also recognised along 592 m of the Łanowicze PIG-1 borehole section, within the AMCG suite. U-Pb geochronology by sensitive high resolution ion microprobe (SHRIMP) was used to date the complexly zoned zircons. The ages of crystallisation of the charnockite protoliths from various depths at 1837±7, 1850±9, 1842±6, and 1881±16 Ma makes these rocks the oldest dated crust within this part of the Polish basement. The Łanowicze PIG-1 borehole section bears components from neighbouring tectonic domains known from Lithuania: the West and Middle Lithuanian (WL/MLD) domains considered as a continental margin at 1.84–1.86 Ga and the fragmented Latvia-East Lithuania (LEL) domain, where the oldest continental crust was generated at c. 1.89– 1.87 Ga. The metamorphic zircon overgrowths document a high-grade event at 1.79 Ga and then constrained at 1.5 Ga. Dating of pre-Mesoproterozoic crust cryptic within the AMCG Mazury Complex provides valuable information on the nature of the pre-existing blocks formed during the long lasting Svecofennian orogeny.
