Nutrition Practices among Adult Cancer Survivors Living on the Island of Ireland: A Cross-Sectional Study

The purpose of this research was to explore the nutrition practices among post-treatment cancer survivors across Ireland. Cancer survivors aged 18+ years living across Ireland, who were not palliative and had completed active cancer treatment at least six months previous, were recruited to complete an online survey assessing dietary quality, food choice and satisfaction with food-related life as well as clinical and nutrition status. It was circulated by cancer support networks and on social media. Descriptive statistics are presented. The cohort (n = 170) was predominantly female (85.9%) and had breast cancer (64.7%). Mean age was 51.5 ± 10.9 years and 42.7% of the cohort were >five years post-treatment. Only 20% and 12% of the cohort had been assessed by a dietitian during and post-treatment, respectively. The mean dietary quality score was 10.3 ± 1.7, which was measured by the Leeds short-form food frequency questionnaire (SFFFQ). Using a 5-point Likert scale, the median satisfaction with food-related life score was 19 (3.3), which evaluates cognitive judgements on the person’s food-related life. The food choice questionnaire (FCQ) assesses the relative importance of a range of factors related to dietary choice to individuals. The primary determinant of food choice in this cohort was the natural content (31.7%) followed by health (24.7%). Vitamin and mineral supplement use was reported by 69.8% of the cohort; the most consumed was Vitamin D. Four themes emerged from an optional open-ended question: awareness of nutritional importance; desire for specific nutritional advice and dietetic referral; cancer and treatment nutrition impacts were highlighted; as well as struggles with weight gain. This research provides useful insight into the nutrition practices of Irish cancer survivors. A desire and need for individualised and specific advice are evident

Key enabling technologies for optical communications at 2000 nm

This paper discusses the potential for opening a new wavelength window at the 2 μm waveband for optical communications, showing current limitations of the system’s performance. It focuses on novel results for key enabling technologies, including the analysis of laser injection locking at this waveband, an improved responsivity for bulk and strained InGaAs edge-couple detectors, and also an increased gain profile for thulium-doped fiber amplifiers

European Sustainable Urbanisation through port city Regeneration - Targeted Analysis Final Report

ENSURE (European Sustainable Urbanisation through port city Regeneration) is a targeted analysis aimed at providing better insights into the potential regional impacts of port city regeneration and a better understanding of the appropriate methods and tools. The research involved a comprehensive literature review, a pan-European desktop analysis of port city regeneration in small and medium-sized cities and in-depth case studies in four stakeholder cities, as well as a series of workshops and conferences. The research shows that a main driver for the development of ports in Europe was the industrial revolution and the continued industrial growth until the mid-20th century. Similarly, a retreat from the waterfront became evident during the last part of the century as the deindustrialisation gathered pace, driven by increased global competition, spatial relocation of industry, and technological changes in both industry and transport. Another key aspect was the collapse of socialism in eastern Europe. Many cities in this part of Europe had active ports that became militarised during the Soviet era and later de-militarised as these states transitioned to a new political-economic structure. The desktop research indicated that about a third of small and medium-sized European port cities (48 of 144) show no evidence of regeneration. Some of these cities may be thriving and have no need for regeneration, but there is likely to be a significant latent potential across the European territory

Development and implementation of an ultralow-dose CT protocol for the assessment of cerebrospinal shunts in adult hydrocephalus

Background: Cerebrospinal fluid shunts in the treatment of hydrocephalus, although associated with clinical benefit, have a high failure rate with repeat computed tomography (CT) imaging resulting in a substantial cumulative radiation dose. Therefore, we sought to develop a whole-body ultralow-dose (ULD) CT protocol for the investigation of shunt malfunction and compare it with the reference standard, plain radiographic shunt series (PRSS). Methods: Following ethical approval, using an anthropomorphic phantom and a human cadaveric ventriculoperitoneal shunt model, a whole-body ULD-CT protocol incorporating two iterative reconstruction (IR) algorithms, pure IR and hybrid IR, including 60% filtered back projection and 40% IR was evaluated in 18 adult patients post new shunt implantation or where shunt malfunction was suspected. Effective dose (ED) and image quality were analysed. Results: ULD-CT permitted a 36% radiation dose reduction (median ED 0.16 mSv, range 0.07–0.17, versus 0.25 mSv (0.06–1.69 mSv) for PRSS (p = 0.002). Shunt visualisation in the thoracoabdominal cavities was improved with ULD-CT with pure IR (p = 0.004 and p = 0.031, respectively) and, in contrast to PRSS, permitted visualisation of the entire shunt course (p < 0.001), the distal shunt entry point and location of the shunt tip in all cases. For shunt complications, ULD-CT had a perfect specificity. False positives (3/22, 13.6%) were observed with PRSS. Conclusions: At a significantly reduced radiation dose, whole body ULD-CT with pure IR demonstrated diagnostic superiority over PRSS in the evaluation of cerebrospinal fluid shunt malfunction

Rehabilitation versus surgical reconstruction for non-acute anterior cruciate ligament injury (ACL SNNAP): a pragmatic randomised controlled trial

BackgroundAnterior cruciate ligament (ACL) rupture is a common debilitating injury that can cause instability of the knee. We aimed to investigate the best management strategy between reconstructive surgery and non-surgical treatment for patients with a non-acute ACL injury and persistent symptoms of instability.MethodsWe did a pragmatic, multicentre, superiority, randomised controlled trial in 29 secondary care National Health Service orthopaedic units in the UK. Patients with symptomatic knee problems (instability) consistent with an ACL injury were eligible. We excluded patients with meniscal pathology with characteristics that indicate immediate surgery. Patients were randomly assigned (1:1) by computer to either surgery (reconstruction) or rehabilitation (physiotherapy but with subsequent reconstruction permitted if instability persisted after treatment), stratified by site and baseline Knee Injury and Osteoarthritis Outcome Score—4 domain version (KOOS4). This management design represented normal practice. The primary outcome was KOOS4 at 18 months after randomisation. The principal analyses were intention-to-treat based, with KOOS4 results analysed using linear regression. This trial is registered with ISRCTN, ISRCTN10110685, and ClinicalTrials.gov, NCT02980367.FindingsBetween Feb 1, 2017, and April 12, 2020, we recruited 316 patients. 156 (49%) participants were randomly assigned to the surgical reconstruction group and 160 (51%) to the rehabilitation group. Mean KOOS4 at 18 months was 73·0 (SD 18·3) in the surgical group and 64·6 (21·6) in the rehabilitation group. The adjusted mean difference was 7·9 (95% CI 2·5–13·2; p=0·0053) in favour of surgical management. 65 (41%) of 160 patients allocated to rehabilitation underwent subsequent surgery according to protocol within 18 months. 43 (28%) of 156 patients allocated to surgery did not receive their allocated treatment. We found no differences between groups in the proportion of intervention-related complications.InterpretationSurgical reconstruction as a management strategy for patients with non-acute ACL injury with persistent symptoms of instability was clinically superior and more cost-effective in comparison with rehabilitation management

Vaping-Associated Lung Injury: A Review

Since commercial development in 2003, the usage of modern electronic cigarette (e-cigarette) continues to increase amongst people who have never smoked, ex-smokers who have switched to e-cigarettes, and dual-users of both conventional cigarettes and e-cigarettes. With such an increase in use, knowledge of the irritative, toxic and potential carcinogenic effects on the lungs is increasing. This review article will discuss the background of e-cigarettes, vaping devices and explore their popularity. We will further summarise the available literature describing the mechanism of lung injury caused by e-cigarette or vaping use
