Employing citizen science to understand the contemporary needs of older adults accessing and using technology in a pandemic

The ‘Adjust Tech, Accessible Technology’ (ATAT) project (2020) aims to understand via citizen science what basic adjustments are required by older adults; to access and use affordable technologies and software - such as mobile apps. Facilitating this multi-and-inter-disciplinary team of researchers from the fields of gerontology, gerontechnology, and human computer interaction (HCI), the research team are employing citizen science across three stages: 1. Co-creation, 2. Co-design and 3. Co-evaluation. Implementing this approach by adults aged 50+ years who are geographically displaced from their family, friends, community groups and networks, we will garner greater understanding of the use, benefits, perceptions, and levels of engagement experienced from both a positive and negative perspective by older adults. Several virtual workshops were conducted with end-users recruited via Digital Voice for Communities (based in the Northeast of England) and Digital Communities Wales. Future workshops will involve demonstrations of existing software available, and prospective prototypes will be shown by paper-based or digital formats. This chapter will contribute to the call because of the methods and approaches ATAT is implementing, through the lens of older adults who have been directly affected by the COVID-19 pandemic. This chapter will provide an insight and a basis for future research teams choosing to engage stakeholders actively and directly into their research

Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)1.

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field

Controversies in acute kidney injury: conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) conference

In 2012, Kidney Disease: Improving Global Outcomes (KDIGO) published a guideline on the classification and management of acute kidney injury (AKI). The guideline was derived from evidence available through February 2011. Since then, new evidence has emerged that has important implications for clinical practice in diagnosing and managing AKI. In April of 2019, KDIGO held a controversies conference entitled Acute Kidney Injury with the following goals: determine best practices and areas of uncertainty in treating AKI; review key relevant literature published since the 2012 KDIGO AKI guideline; address ongoing controversial issues; identify new topics or issues to be revisited for the next iteration of the KDIGO AKI guideline; and outline research needed to improve AKI management. Here, we present the findings of this conference and describe key areas that future guidelines may address

Challenges and opportunities for conducting a vaccine trial during the COVID-19 pandemic in the United Kingdom

The COVID-19 pandemic has resulted in unprecedented challenges for healthcare systems worldwide. It has also stimulated research in a wide range of areas including rapid diagnostics, novel therapeutics, use of technology to track patients and vaccine development. Here, we describe our experience of rapidly setting up and delivering a novel COVID-19 vaccine trial, using clinical and research staff and facilities in three National Health Service Trusts in Cambridgeshire, United Kingdom. We encountered and overcame a number of challenges including differences in organisational structures, research facilities available, staff experience and skills, information technology and communications infrastructure, and research training and assessment procedures. We overcame these by setting up a project team that included key members from all three organisations that met at least daily by teleconference. This group together worked to identify the best practices and procedures and to harmonise and cascade these to the wider trial team. This enabled us to set up the trial within 25 days and to recruit and vaccinate the participants within a further 23 days. The lessons learned from our experiences could be used to inform the conduct of clinical trials during a future infectious disease pandemic or public health emergency

European guidelines for the management of diabetes, prediabeties and cardiovascular disease. First part. Management of diabetes and cardiovascular risk factors

peer reviewedThe patient with prediabetes or diabetes has a high or very high risk of cardiovascular diseases.We summarize the recent guidelines jointly published by the European Society of Cardiology and the European Society for the Study of Diabetes. In this first article, we focus mainly on the preventive approaches of cardiovascular diseases in patients with prediabetes or (type 1 or type 2) diabetes. The crucial importance of a global multifactorial strategy is emphasized and the target levels of various risk factors are updated. The management of these cardiovascular complications in presence of diabetes will be considered in a second article.Résumé : Le patient avec une dysglycémie (pré-diabète) ou un diabète est à haut risque ou très haut risque cardio-vasculaire. Nous résumons les dernières recommandations conjointes des sociétés européennes de cardiologie et de diabétologie publiées récemment, en se focalisant dans ce premier article essentiellement sur les approches de prévention des complications cardio-vasculaires chez le patient diabétique (de type 1 ou de type 2) ou pré-diabétique. L’importance d’une stratégie globale multifactorielle est mise en exergue, en réactualisant les principales valeurs cibles à atteindre. La prise en charge de ces complications cardio-vasculaires en présence d’un diabète sera envisagée dans un second article

Therapy of Type 2 Diabetes: Between Insulin Sensitizers and Insulin Secreting Agents

peer reviewedType 2 diabetes is a complex disease characterized by a dual defect of insulin secretion and insulin sensitivity, which may vary from patient to patient, but also along the natural history of the disease in a particular patient. Besides the lifestyle changes, the treatment strategy comprises the administration of agents that promote insulin secretion and/or that improve insulin sensitivity. Drugs facilitating weight loss also improve glucose control by reducing insulin resistance. A global approach should be recommended to reduce the high cardiovascular risk of diabetic patients. The present article aims at summarizing our contribution to the development of drugs designed for the treatment of type 2 diabetes.: Le diabète de type 2 est une maladie bipolaire caractérisée par une combinaison d’un déficit insulinosécrétoire et d’une d’insulinorésistance, en proportion variable selon les patients, et, chez un même sujet, en fonction de la durée d’évolution de la maladie. Outre les mesures hygiéno-diététiques, la stratégie thérapeutique fait appel à la prescription de médicaments insulinosécrétagogues et/ou d’agents insulinosensibilisateurs. Les médicaments favorisant une perte de poids améliorent aussi le contrôle glycémique en diminuant l’insulinorésistance. Une prise en charge globale est privilégiée pour réduire la forte morbi-mortalité cardio-vasculaire associée à cette maladie. Cet article a pour but de résumer la contribution de notre service dans la mise au point et l’évaluation des médicaments développés pour le traitement du diabète de type 2

A feasibility trial of prehabilitation before oesophagogastric cancer surgery using a multi-component home-based exercise programme: the ChemoFit study

BACKGROUND: Treatment for locally advanced oesophagogastric adenocarcinoma involves neoadjuvant chemotherapy which has a negative impact on patient fitness. Using ‘prehabilitation’ to increase activity levels and fitness may affect physiology, postoperative outcomes and improve patient wellbeing and quality of life. The aims of the trial were to address the feasibility and acceptability of recruiting participants to a home-based prehabilitation programme and provide data to allow design of future studies. METHODS: We recruited patients to a single-arm feasibility trial of home-based exercise prehabilitation. Eligible patients were aged ≥18years, had operable oesophageal or gastric adenocarcinoma and were receiving neoadjuvant chemotherapy at our tertiary referral hospital. All participants commenced a home-based exercise programme utilising pedometers and step counting to target daily aerobic exercise sessions alongside daily strengthening exercises. A weekly telephone consultation directed the exercise programme and facilitated weekly data collection. The primary (feasibility) outcomes for the trial were (a) recruitment rate, (b) completion rate, (c) engagement with the programme (use of pedometers, recording step counts, telephone consultations) and (d) compliance with exercise sessions, exercise intensity and strengthening exercises. RESULTS: There were 42 patients recruited, and the recruitment rate was 72.4% (42/58). 92.3% (36/39) of patients completed the exercise programme. There was 98.7% (IQR 93.2–100.0%) compliance with wearing a pedometer and recording data, and 100.0% (IQR 93.1–100.0%) compliance with a weekly telephone consultation. Exercise sessions and strengthening exercises were completed 70.2% (IQR 53.1–88.9%) and 69.4% (IQR 52.1–84.3%) of the time, respectively. Appropriate exercise intensity was recorded 96% (IQR 85.4–99.4%) of the time. There were no adverse events. Participants were enrolled in the exercise programme for a median of 91 days (IQR 84 to 105 days). CONCLUSIONS: The results of this trial support the feasibility and acceptability of recruiting participants to an appropriately powered randomised controlled trial of prehabilitation. TRIAL REGISTRATION: Clinicaltrials.gov NCT04194463. Registered on 11th December 2019—retrospectively registered. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s40814-022-01137-6

Exploring factors influencing uptake and adherence to a home-based prehabilitation physical activity and exercise intervention for patients undergoing chemotherapy before major surgery (ChemoFit):A qualitative study

OBJECTIVES: Preoperative exercise training can improve cardiorespiratory fitness before major surgery. However, little is known about what influences participation and adherence in high-risk patient groups. We identified barriers and facilitators to uptake, engagement and adherence to a presurgical, home-based physical activity and exercise intervention called ChemoFit delivered during chemotherapy and before major oesophagogastric surgery. DESIGN: A qualitative study using focus group discussions and individual semi-structured interviews was conducted. All were audio-recorded, transcribed verbatim and data thematically analysed. SETTING: Northern Oesophagogastric Unit, Royal Victoria Infirmary, Newcastle upon Tyne NHS Hospitals Foundation Trust. PARTICIPANTS: Patients with oesophagogastric cancer who participated in the ChemoFit intervention recruited between March 2020 and January 2021. INTERVENTION: A home-based physical activity and exercise intervention involving cardiovasular and strength exercise using resistance bands and pedometers to monitor step count. Weekly telephone calls provided feedback, support and positive reinforcement. RESULTS: Twenty-two participants (18 men, 4 women; aged 67±8 years old) took part in a focus group discussion (n=17) or a semi-structured interview (n=5). Fifteen themes were identified from the data generated. Participants reported that the intervention was physically and mentally beneficial, and data highlighted features of the intervention that influenced uptake and adherence. An opportunity to increase the likelihood of surviving the pending operation was reported by participants as the most salient factor to engagement, and using the intervention as a distraction from illness and taking steps to positively influence the situation were the most salient factors to adherence. CONCLUSIONS: Uptake to the ChemoFit intervention was encouraged by provision of information that participation could reduce surgical risk and that participants could play an active role in risk reduction. Adherence was facilitated by the intervention being considered a positive distraction and participants being able to do something that could ultimately provide benefit. While participants reported difficulties and avoidance with some of the exercises recommended, understanding the importance of physical activity and exercise as part of their treatment regimen led to individual adaptations to intervention components to reach individual goals.
