BACKGROUND All studies need to integrate their findings back into the literature to explain how the new knowledge changes understanding. This process can be anxiety-provoking, especially when new literature appears to threaten the originality of the study. AIM To reintroduce ‘concurrent analysis’ (CA) – a method of synthesising relevant literature with primary data. DISCUSSION CA treats all data as primary data. To illustrate the technique, the authors synthesise relevant literature with findings from a doctoral study of patients’ experiences of vascular access devices. CONCLUSION CA raised new questions that would otherwise have remained unasked. For example, it revealed cultural differences in the way patients react to suboptimal treatment. IMPLICATIONS for practice Nurse researchers are best placed to influence policy and practice when they can articulate the transferability of their findings. CA is a practical method of achieving this. © 2020 RCN Publishing Company Ltd. All rights reserved.

However, the physiological activity and cell viability in such constructs might be impaired due to a lack of oxygen and nutrients. Photobiomodulation (PBM) is a promising method of preconditioning cells to increase their metabolic activity and to activate proliferation or differentiation. AIM Investigation of the potential of PBM for stimulation of cell activities in hydrogels. APPROACH Mesenchymal stromal cells (MSCs) isolated from human gingival mucosa were encapsulated in modified fibrin hydrogels with different thicknesses and concentrations. find more Constructs with cells were subjected to a single-time exposure to red (630 nm) and near-infrared (IR) (840 nm) low-intensity irradiation. After 3 days of cultivation, the viability and physiological activity of the cells were analyzed using confocal microscopy and a set of classical tests for cytotoxicity. RESULTS The cell viability in fibrin hydrogels depended both on the thickness of the hydrogels and the concentration of gel-forming proteins. The PBM was able to improve cell viability in hydrogels. The most pronounced effect was achieved with near-IR irradiation at the 840-nm wavelength. CONCLUSIONS PBM using near-IR light can be applied for stimulation of MSCs metabolism and proliferation in hydrogel-based constructs with thicknesses up to 3 mm.The use of the combined herbal preparation Cystenium II for the prevention of recurrent lower urinary tract infections, including those in children and pregnant women, is described in the review. The etiological component of infectious and inflammatory diseases of the lower urinary tract and specific features of the interaction of microorganisms with bladder mucosa were studied. A detailed analysis of pharmacodynamic effects of Cysteniums II components is provided. The specific features of the treatment of acute cystitis in pregnant women and children older than 7 years are presented.Urinary tract infections are one of the most common and widespread infectious diseases. A certain role in etiopathogenesis may play genetic predisposition, as well as a decrease in antiadhesive properties and an increase in urothelium permeability due to incompetence of bladder glycosaminoglycan layer. The prevalence of infectious diseases increases significantly with age, as well as in patients with chronic diseases. The introduction of modern biotechnology has allowed clinicians to greatly expand therapeutic armamentarium, while having a number of advantages, including minimal frequency of complications and adverse events, the possibility for long-term use, accessibility, and etc. Priority research areas include the study of toll-like receptors, which are transmembrane proteins that provide pathogen recognition and activate the immune response. The role of these receptors in the development of the immune response to urinary tract infections was evaluated in our study, which allows to predict the course of the disease and to increase treatment efficiency.The active development of minimally invasive procedures on retroperitoneal organs using endoscopic technology raises the question of the most rational approach. The studies dedicated to the comparison of transperitoneal and retroperitoneoscopic approach are analyzed in the article. The advantages and the most common complications, as well as the factors limiting the widespread use of retroperitoneoscopic approach, are reviewed.Percutaneous nephrolithotomy (PCNL) is the method of choice for large and staghorn renal stones, including those in patients with solitary kidney. The aim of the literature review was to analyze the results of PCNL in patients with large stones in the solitary kidney. The literature search was conducted in databases Embase, Medline, Google Scholar, Scopus for the period from 2010 to 2019. A total 94 articles were selected, of which 16 papers were included in the review after analyzing the abstracts. Data was pooled and analyzed using SPSS Statistics 22.0. The primary stone-free rate for PCNL in these patients was 68.3+/-14.2%, and the final stone-free rate increased by 86.5+/-4.9%. The average duration of the operation was 86+/-25 (43.7-138.3) min, the length of stay was 5 (2-6) days. The baseline creatinine level was 137 (110-200) mmol/L, compared to 142 (122-183) mmol/L postoperatively. The mean difference between the baseline and postoperative Hb level was 7.8 (1.3-17.5) g/l. The estimated glomerular filtration rate (GFR) before PCNL was 62.3+/-7.5 ml/min/1.73 m2, and it did not exceed 62.5+/-9.3 ml/min/1.73 m2 postoperatively. The overall complication rate ranged from 10.6 to 68.8%, averaging 29.9%. In most cases, there were grade I and II complications, according to Clavien-Dindo classification, which didnt require additional interventions. PCNL is a highly effective treatment method for patients with large stones in solitary kidney. Complications rate is relatively low, which is achieved by an individual approach, with a consideration of the condition and all risk factors.
