Aim/purpose – The purpose of this article was to identify the information and communication technology (ICT) tools fostering the co-production of social services, acknowledging that the technological environment is an important contextual condition enhancing the development of co-production. Design/methodology/approach – The method used was systematic literature review (SLR). Findings – As a result of the review, the catalog of solutions and tools offered by information and communication technologies was presented. The results of the research carried out indicate that the co-production of social services is favored by the use of such ICT tools as mobile applications, crowdsourcing, open data, big data, real-time data collection and analysis, gamification, and social media. Research implications/limitations – The main implication of the research is the comprehensive catalog of ICT tools that can be used to facilitate social service co-production. ICT tools also favor the emergence of new forms of co-production; there-fore, the acquaintance of these tools can accelerate this process. The study is constrained by several limitations. The study is constrained by several limitations. First, applied methodology, which is qualitative, analyzes secondary data. Second, the co-production in the social services area includes many and various services, and ICT application and impact can differ by specific type of service. Originality/value/contribution – This paper contributes to research on the co-production of social services, particularly in terms of the use of new technologies in this process, in two ways. First, the development of the catalog of ICT tools favoring social service co-production. Their application fosters the involvement of contextual actors, increasing the efficiency, effectiveness, and quality of social services. In this way, the social service co-production contributes to better addressing the citizens’ needs, increasing their quality of life and well-being, and unleashing their potential. Second, by taking the PSL perspective and situating factors favoring co-production within a service ecosystem framework, this paper draws attention to public value emerging from new relations, extensive dialogue, deliberation, common arrangements, and collaborative activity in virtual communities.

Two kinds of Pluronics (PEO-PPO-PEO triblock copolymers) were used in these studies. They have mixed with anionic surfactant (sodium oleate). The adsorption isotherms of surfactant and copolymer-surfactant mixture onto dolomite have been determined.The adsorbed amount of the Pluronics increases with increasing concentration and reaches plateau. An increase of adsorbed amounts of anionic surfactant onto the mineral surfaces (dolomite) has been observed at the presence of Pluronic copolymers. The adsorption effect of triblock copolymers has been investigated on the zeta potential of dolomite at the water suspension. The interaction of anionic surfactant with copolymers causes a decrease of zeta potential to small amount due to the deformation of double electrical layer. The adsorbed non-ionic Pluronic layer partially screens the surface charge of mineral particles, and thus, reduces the zeta potential. On the other hand, the adsorption of anionic surfactant and copolymer caused a decrease of negative value of zeta potential both investigated minerals. The stability of dolomite suspension depends on the both copolymer and sodium oleate concentrations.

Objectives: Wood dust is a known occupational allergen that may induce, in exposed workers, respiratory diseases including asthma and allergic rhinitis. Samba (obeche, Triplochiton scleroxylon) is a tropical tree, which grows in West Africa, therefore, Polish workers are rarely exposed to it. This paper describes a case of occupational asthma caused by samba wood dust. Material and Methods: The patient with suspicion of occupational asthma due to wood dust was examined at the Department of Occupational Diseases and Clinical Toxicology in the Nofer Institute of Occupational Medicine. Clinical evaluation included: analysis of occupational history, skin prick tests (SPT) to common and occupational allergens, determination of serum specific IgE to occupational allergens, serial spirometry measurements, metacholine challenge test and specific inhalation challenge test with samba dust. Results: SPT and specific serum IgE assessment revealed sensitization to common and occupational allergens including samba. Spirometry measurements showed mild obstruction. Metacholine challenge test revealed a high level of bronchial hyperactivity. Specific inhalation challenge test was positive and cellular changes in nasal lavage and induced sputum confirmed allergic reaction to samba. Conclusions: IgE mediated allergy to samba wood dust was confirmed. This case report presents the first documented occupational asthma and rhinitis due to samba wood dust in wooden airplanes model maker in Poland.

ntroduction: The surgeon’s viewpoint on a patient with cystic fibrosis differs from that of a pediatrician or internist. The problems a cystic fibrosis specialist encounters are different from those faced by the surgeon who takes over the patient in a very advanced, often terminal stage of the disease. Hence, the main problem for the surgeon is the decision concerning the surgery (lung transplantation, pneumonectomy, lobectomy). It is, therefore, important to lay down fundamental and appropriate rules concerning the indications and contraindications for lung transplantation, especially in patients with cystic fibrosis. Aim: The aim of this study was to analyze the methods of qualifying and preparing patients for surgery, as well as carrying out the procedure of transplantation and postoperative short and long-term care. Material and methods: The investigation was carried out on 16 patients with cystic fibrosis. Three were operated on and 10 were on the waiting list for transplantation. Two patients on the waiting list died, one patient was disqualified from transplantation. During qualification for lung transplantation, strict indications, contraindications and other factors (such as blood type, patient’s height, coexisting complications) were taken under consideration. Results: All the 3 patients after lung transplantation are alive and under our constant surveillance. Ten patients await transplantation, though four of them are suspended due to hepatitis C infection. Two patients on the waiting list died: one from respiratory insufficiency and the other in the course of bridgeto-transplant veno-venous extracorporeal membrane oxygenation due to hepatic failure. One patient has been disqualified because of cachexia. Conclusions: Since lung transplantation is the final treatment of the end-stage pulmonary insufficiency in cystic fibrosis patients, the number of such procedures in cystic fibrosis is still too low in Poland. The fast development of these procedures is highly needed. It is necessary to develop better cooperation between different disciplines and specialists, especially between pediatricians and surgeons. The correct choice of the suitable moment for lung transplantation is crucial for the success of the procedure.

Wstęp: Punt widzenia chirurga odnośnie leczenia pacjenta z mukowiscydozą różni się od spojrzenia pediatry czy internisty. Duży jest bagaż zadań lekarza specjalisty w zakresie leczenia chorego z mukowiscydozą w różnych okresach choroby, a inny chirurga, który przejmuje go w bardzo zaawansowanym, a nierzadko w terminalnym stadium. Stąd dla chirurga głównym problemem jest podjęcie decyzji odnośnie leczenia operacyjnego (transplantacja płuc, pneumonektomia, lobektomia). Dlatego tak ważne jest sformułowanie podstawowych i właściwych zasad dotyczących wskazań i przeciwwskazań do transplantacji płuc zwłaszcza w odniesieniu do pacjentów z mukowiscydozą. Cel: Celem pracy była analiza metod kwalifikacji i przygotowania, a także przeprowadzenia transplantacji oraz pooperacyjnej opieki krótko- i długoterminowej. Materiał i metody: W niniejszej pracy przedstawiamy 3 przypadki pacjentów z mukowiscydozą po zabiegu transplantacji płuc oraz 10 kandydatów, którzy w chwili obecnej są potencjalnymi biorcami narządu i oczekują na jej przeprowadzenie. Dwóch pacjentów nie doczekało przeszczepienia, jedna pacjentka została zdyskwalifikowana z zabiegu. W toku kwalifikacji do transplantacji płuc omawiane są istniejące wskazania, przeciwwskazania i szereg innych czynników (takich jak grupa krwi, wysokość ciała pacjenta, istniejące powikłania choroby podstawowej, choroby współistniejące). Wyniki: Wszyscy (troje) pacjenci po przeprowadzonej transplantacji żyją i są pod stałą kontrolą naszego ośrodka. Z dziesięciu kandydatów oczekujących na przeszczepienie, czterech jest zawieszonych na liście oczekujących z powodu infekcji (wirusowe zapalenie wątroby typu C). Dwóch pacjentów nie doczekało przeszczepienia: pierwszy zmarł z powodu niewydolności oddechowej, adrugi kwalifikowany do przeszczepienia płuc iwątroby pozostający na pozaustrojowym natlenianiu membranowym żylno-żylnym, zmarł wskutek niewydolności wątroby. Jedna pacjentka została zdyskwalifikowana z zabiegu z powodu skrajnego niedoboru masy ciała. Wnioski: Biorąc pod uwagę, że transplantacja płuc jest ostatecznym leczeniem schyłkowej niewydolności oddechowej w mukowiscydozie. Liczba wykonywanych w Polsce przeszczepień płuc u chorych z mukowiscydozą jest ciągle za mała, o czym świadczy los oczekujących pacjentów. Konieczny jest więc szybki rozwój placówek zajmujących się przeszczepieniami płuc u tych chorych. Wybór odpowiedniego momentu przeprowadzenia transplantacji płuc, ma zasadnicze znaczenie dla powodzenia procedury.
