Based on the limited existing information, the health risk of drinking glacial water can be considered negligible, but consuming aquatic organisms from these waters may increase the risk of cancer. Remoteness from emission sources is a leading factor in the presence of such risk, yet the Arctic is likely to be more exposed to it in the future due to large-scale processes shifting atmospheric pollution and the continuous supply of snow. For future risk monitoring, we recommend to explore the synergistic toxic effects of multiple contaminants and fill the gaps in the spatial distribution of data.The approval of the coronavirus disease 2019 (COVID-19) mRNA vaccines brought much optimism to efforts to end the pandemic. A recombinant adenovirus vaccine recently received emergency use authorization, and several other vaccines are likely to follow. These vaccines all use relatively new vaccine production platforms to produce the severe acute respiratory syndrome coronavirus 2 Spike protein. This review discusses how these platforms work, what advantages they offer, and the gaps that remain in public health efforts to control the COVID-19 pandemic.

Gaining a better understanding of CAR-induced T cell activation would help identify and remediate the causes of treatment failure. Increasingly, technologies to analyze the transcriptome are used to molecularly profile the behavior of CAR-T cells, both before and after treatment. Here, we describe recent work on how gene expression signatures, especially those obtained from single-cell RNA sequencing (scRNA-seq), can be used to characterize CAR design, production conditions, therapy combinations, and finally disease outcome. In the future, scRNA-seq could become a standard tool for the development and clinical monitoring of CAR-T cell therapies.Chemotherapy remains the most widely used cancer treatment modality. Nanotechnology provides exciting opportunities to improve these drugs, transforming decades-old generic treatments into precise new medicines. We illustrate the potential of recent advances in nanotechnology-enhanced therapy focusing on diffuse large B-cell lymphoma (DLBCL); the most common hematologic malignancy.A new model of complex patient care after acute myocardial infarction (AMI) has been in operation in Poland since late 2017, comprising invasive treatment, cardiac rehabilitation and scheduled outpatient follow-up. Its stated objectives are to improve secondary prevention measures, quality of care and long-term health outcomes in AMI-patients. The model implements all key aspects of post-MI care recommended by the European Society of Cardiology (ESC), representing the first nation-wide model of structured and comprehensive post-MI care that closely follows ESC guidelines. The aim of this paper is to describe the background of this reform, its content and implementation as well as to assess its results. Early outcomes seem promising, with significantly lower mortality rate and lower risk of serious cardiological events in patients participating in the new model of care compared to patients who were not included. A comprehensive assessment of the reform will require further clinical data, covering a larger population and a longer period of time, as well as a holistic analysis of the programme in its wider context, taking into account potential benefits and cost-effectiveness of improved primary prevention implemented outside of this model.The challenges facing Quality Improvement Managers (QIMs) are often understood and addressed in isolation from wider healthcare organisation within which quality improvement initiatives are embedded. We draw on Stafford Beer's Viable System Model (VSM) to shed light on how the viability of quality improvement depends on the effective functioning of five critical quality improvement systems and the extent to which these systems are integrated within the healthcare organisation. These systems are System 1 (Operations), System 2 (Coordination), System 3 (Operational Control), System 4 (Development) and System 5 (Policy). Our analysis draws on interviews with 56 QIMs working in 15 of New Zealand's 20 District Health Boards. We use VSM to identify the sources of problems in QI implementation. These include changes in direction for QI initiatives; myopic behaviour resulting from fragmented systems of care; difficulties in managing and monitoring QI activities given variable staff engagement and inadequate resourcing; pressure for quick results rather developing QI capabilities; and a lack of strategic embeddedness. A viable QI system requires QI approaches that are (1) implemented at an organisation-wide level; (2) well-resourced and carefully monitored; (3) underpinned by a long-term vision; and (4) supported by QIMs with the necessary power and influence to integrate QI subsystem within the wider healthcare organisation.

Sexual dysfunctions seriously affect the quality of life of patients. The aim of this study was to identify the risk factors for sexual dysfunction after rectal cancer surgery.

A total of 948 consecutive patients undergoing rectal cancer radical resection were included between January 2012 and August 2019. The sexual functions were evaluated by the 5-item version of the International Index of Erectile Function (IIEF-5) in men and Index of Female Sexual Function (IFSF) in women at 12 months postoperatively.

Postoperative sexual dysfunction was observed in 228 patients with rectal cancer (24.05%), which included 150 cases in male patients (25.0%) and 78 cases in female patients (22.5%). A multivariate logistic regression analysis results showed that age ≥45 years old (OR=1.72, p=0.001), tumor below the peritoneal reflection (OR=1.64, p=0.005), receiving preoperative radiotherapy (OR=4.12, p<0.001) and undergoing abdominoperineal resection (APR), intersphincteric resection (ISR) and Hartmann surgery (OR=2.
