There are several steps in the transfusion process that aim to ensure the correct blood component is given to the correct patient at the correct time. Ensuring the correct blood component is collected for the correct patient is crucial to safe transfusion practice and patient safety. This article explains the blood component collection and delivery procedure in the UK and outlines the steps that are necessary to enable nurses to collect blood components safely. Nurses in other countries can access their local guidelines and protocols and review these against the guidelines outlined in this article.<br />How to articles can help to update your practice and ensure it remains evidence based.

The first article explored global and UK trends in asthma and asthma care as they relate to children and young people, while the second article identified the adverse effects of air pollution on children, particularly those with asthma. This article explores the potentially significant psychosocial effects of asthma on the child and the family. A family-centred approach to care relies on healthcare professionals listening to and understanding families' health beliefs and narratives to target asthma education and aid self-efficacy, which can improve asthma control and quality of life.<br />Women with menopausal symptoms show evidence of accelerated epigenetic ageing, vascular aging and low-grade systemic inflammation status. However, data are limited regarding menopausal symptoms and risk of heart failure (HF). We aimed to explore the impact of menopausal symptoms on risk of HF.<br />We included 14 340 symptomatic menopausal women without a history of coronary heart disease (CHD) or HF from the Taiwan National Health Insurance Research Database as the experimental cohort. We included 14 340 asymptomatic women matched for age and comorbidities as controls. We surveyed possible comorbidity-attributable risks of HF and assessed whether menopausal symptoms play a role in risk of HF. Additional analyses were conducted to ascertain the association of CHD and HF in different risk factor burdens categories in both cohorts and CHD was applied as a sensitivity analysis.<br />The incidence of HF was not significantly lower in the experimental than in the control cohort (4.87 vs. 5.06 per 1000 person-years, P=0.336). Participants with a higher comorbidity burden had a proportionally increased risk of HF and CHD in both cohorts. The burden of risk factors had a greater impact on risk of HF in the control than in the experimental cohort (≥five risk factors, adjusted hazard ratio 25.69 vs. 14.75). Participants undergoing hormone therapy had no significant effect on the risk of HF, regardless of the presence or absence of menopausal symptoms. Subgroup analysis revealed that compared with the control cohort, the risk of HF in the experimental cohort did not increase significantly in all subgroups.<br />Menopausal symptoms were associated with CHD risk but not with risk of HF. Traditional risk factors rather than menopausal symptoms play important roles in the HF risk among middle-aged women.<br />Menopausal symptoms were associated with CHD risk but not with risk of HF.

However, an understanding of how this unique topology can affect the properties of highly solvated materials like hydrogels remain under investigated. Here, it is investigated how the high functionality and large overall size of brush polymers enhances the gelation kinetics of low polymer weight percent gels, enabling 100-fold faster gelation rates and 15-fold higher stiffness values than gels crosslinked by traditional star polymers of the same composition and polymer chain length. This work demonstrates that brush polymer topology provides a useful means to control gelation kinetics without the need to manipulate polymer composition or crosslinking chemistry. The unique architecture of brush polymers also results in restrained or even nonswelling behavior at different temperatures, regardless of the polymer concentration. Brush polymers therefore are an interesting tool for examining how high-functionality polymer building blocks can affect structure-property relationships and chemical kinetics in hydrogel materials, and also provide a useful rapidly-setting hydrogel platform with tunable properties and great potential for multiple material applications.<br />Frailty is associated with prognosis of cardiovascular diseases. However, the significance of frailty in patients with heart failure with preserved ejection fraction (HFpEF) remains to be elucidated. The purpose of this study was to examine the prognostic significance of the Clinical Frailty Scale (CFS) in real-world patients with HFpEF using data from a prospective multicentre observational study of patients with HFpEF (PURSUIT-HFpEF study).<br />We classified 842 patients with HFpEF enrolled in the PURSUIT-HFpEF study into two groups using CFS. The registry enrolled patients hospitalized with a diagnosis of decompensated heart failure. Median age was 82 [interquartile range 77, 87], and 45% of the patients were male. Of 842 patients, 406 were classified as high CFS (CFS≥4, 48%) and 436 as low CFS (CFS≤3, 52%). The primary endpoint was the composite of all-cause mortality and heart failure admission. Secondary endpoints were all-cause mortality and heart failure admission. Patients with high CFS were older (8y associated with composite endpoint (adjusted HR 1.23, 95% CI 1.11-1.36, P &lt; 0.001), all-cause mortality (adjusted HR 1.32, 95% CI 1.13-1.55, P = 0.001) and heart failure admission (adjusted HR 1.15, 95% CI 1.02-1.30, P = 0.021).<br />Frailty assessed by the CFS was associated with poor prognosis in patients with HFpEF.<br />Frailty assessed by the CFS was associated with poor prognosis in patients with HFpEF.
