Migrations in our common home: Responding with care - Ireland's response to the Ukrainian crisis

Policy Brief produced by the Roundtable on Migrations in Our Common HomeIreland’s response to the Ukrainian migrants has been almost exemplary and this “human rights first” approach should be the blueprint for a reshaping of Ireland’s International Protection system. Beyond the immediate challenges faced by Ukrainian people forcibly displaced, the wider geopolitical impacts of the crisis – the dependency on Russian fossil fuel production and resultant risks, together with risks to food security – will be felt globally into the future, and disproportionately impact those who can least absorb them. Ireland needs to focus on the care, human rights and wellbeing of all. The legitimate expectations of people living in Ireland are not being met. This is most obvious in areas such as housing and homelessness, a two-tier healthcare system, the deepening rural-urban divide, and high levels of poverty and social exclusion, especially among children. These are all areas that must be grappled with in addition to our response to the Ukrainian crisis. This policy briefing takes a look at the key issues and makes a series of policy recommendations aimed at addressing immediate and future challenges

Migrations in our common home: Planning for change - Climate change and migration

Policy briefing on Ireland's response to climate migration in the context of COP27Migration linked to climate change did not get the attention it deserves at COP27. The Global North must accept responsibility for its role in driving climate change and abide by their commitments made to schemes which address worsening conditions for those in the Global South – according to the Roundtable on Migration in Our Common Home. COP27 marks thirty years since the adoption of the United Nations Framework Convention on Climate Change. As the world grapples with the devastating consequences of intensifying climate change, this policy brief examines how climate change is impacting migration, displacement and food security. As COP27 draws to a close, this policy brief looks at the pledges made by Ireland, as well as Ireland’s obligations to Official Development Assistance (ODA) and Climate Finance and the compelling argument in favour of Loss and Damage funding made by the Global south for over three decades. As COP27 draws to a close, the Roundtable expresses its disappointment at the lack of ambition evident in Ireland’s response and the repackaging of previously announced, and inadequate, policies

The association of oral processing and salivary flow rate on food intake and appetite in older adults (aged ≥ 65 years)

Loss of appetite in older adults is common and can lead to reduced food intake, increasing the risk of malnutrition, frailty, and mortality. In addition, older adults often experience age-related deterioration in oral processing ability, saliva flow and chewing efficiency, which can further reduce food intake. This observational study investigated individual variations in these factors and their relative influence on food intake and appetite in healthy adults aged ≥ 65 years. After overnight fast, stimulated and unstimulated saliva samples were collected. A breakfast meal was provided, which was video recorded to enable a subsequent behavioural annotation of bites, chews and swallows using the software “ELAN”. Fasting and postprandial blood glucose were measured. Chewing efficiency was assessed using a two-colour chewing gum mixing ability test and the opto-electronic software ViewGum© (version 4.1.2.1). Saliva uptake was assessed using standard test food, and questionnaire data were collected to assess oral health, lifestyle and sensory preferences. Appetite was assessed subjectively using visual analogue scales for three hours after breakfast and objectively through an ad libitum lunch. Preliminary results from 44 participants (median age 72.5 years, BMI 25.6 kg/m2, 22 males) are presented (target sample size of the study is 86 participants). Males were observed to be faster eaters, with larger average bite size and higher saliva uptake values. Faster eaters had a larger ad libitum meal intake and consumed their meal with a larger average bite size, fewer chews per gram, and shorter total oral exposure time. Individuals with a faster eating rate consumed more food and these differences were associated with differences in subjective satiety ratings, postprandial blood glucose and stimulated saliva flow. No differences in chewing performance were observed. This study is the first to explore the association between oral processing and salivary factors with food intake and appetite in older adults. The preliminary results show that variability between individuals can influence food intake, glucose metabolism and post-meal satiety. This study will provide a foundation for better understanding the food needs of older adults and assist in designing appropriate food products for them

Combined effect of eating speed instructions and food texture modification on eating rate, appetite and later food intake

Modifying food texture and eating slowly each reduce appetite and energy intake. No study has evaluated the effect of combining these measures to slow eating speed and determine the effect on appetite. The aim of this study was to investigate whether there is a combined effect of manipulating oral processing behaviours (OPBs) in this manner on self-reported satiety and subsequent food intake. A 2 × 2 design was used with four breakfast conditions in total. Twenty-four participants attended four study visits where they were asked to consume one of two isocaloric fixed-portion breakfasts differing in texture: 1) granola with milk and 2) yogurt with muesli and conserve. Participants consumed each breakfast twice, with verbal instructions to chew slowly at one visit and at a normal rate at another. Consumption was video-recorded to behaviourally code OPBs. Participants completed visual analogue scales of self-reported appetite measures at the beginning of the test session, immediately prior to and immediately after breakfast consumption. They also completed a food diary documenting food intake for the remainder of the day. The breakfast designed to be eaten slowest (the harder-textured meal with instructions to eat slowly) was eaten at a slower rate, with a greater number of chews per bite and a slower bite rate (p < 0.001) compared to the other meals. No differences were observed between the breakfast conditions on subjective measures of post-prandial satiety, or subsequent energy or macronutrient consumption. Results of this study highlight that combined effects of texture and instructions are most effective at reducing eating rate, though eating slower was not shown to enhance post-meal satiety. Reduced eating speed has previously been shown to reduce ad-libitum energy intake. Future research should consider combined approaches to reduce eating speed, to mitigate the risk of overconsumption within meals

Cell death in cancer in the era of precision medicine

Tumors constitute a large class of diseases that affect different organs and cell lineages. The molecular characterization of cancers of a given type has revealed an extraordinary heterogeneity in terms of genetic alterations and DNA mutations; heterogeneity that is further highlighted by single-cell DNA sequencing of individual patients. To address these issues, drugs that specifically target genes or altered pathways in cancer cells are continuously developed. Indeed, the genetic fingerprint of individual tumors can direct the modern therapeutic approaches to selectively hit the tumor cells while sparing the healthy ones. In this context, the concept of precision medicine finds a vast field of application. In this review, we will briefly list some classes of target drugs (Bcl-2 family modulators, Tyrosine Kinase modulators, PARP inhibitors, and growth factors inhibitors) and discuss the application of immunotherapy in tumors (T cell-mediated immunotherapy and CAR-T cells) that in recent years has drastically changed the prognostic outlook of aggressive cancers. We will also consider how apoptosis could represent a primary end point in modern cancer therapy and how “classic” chemotherapeutic drugs that induce apoptosis are still utilized in therapeutic schedules that involve the use of target drugs or immunotherapy to optimize the antitumor response
