ABSTRACT

Autophagy is a cellular degradation pathway mediated by highly conserved autophagy-related genes (Atgs). In our previous work, we showed that inhibiting autophagy under starvation conditions leads to significant physiological changes in the insect vector of Chagas disease Rhodnius prolixus; these changes include triacylglycerol (TAG) retention in the fat body, reduced survival and impaired locomotion and flight capabilities. Herein, because it is known that autophagy can be modulated in response to various stimuli, we further investigated the role of autophagy in the fed state, following blood feeding. Interestingly, the primary indicator for the presence of autophagosomes, the lipidated form of Atg8 (Atg8-II), displayed 20%-50% higher autophagic activation in the first 2 weeks after feeding compared to the third week when digestion was complete. Despite the elevated detection of autophagosomes, RNAi-mediated suppression of RpAtg6 and RpAtg8 did not cause substantial changes in TAG or protein levels in the fat body or the flight muscle during blood digestion. We also found that knockdown of RpAtg6 and RpAtg8 led to modest modulations in the gene expression of essential enzymes involved in lipid metabolism and did not significantly stimulate the expression of the chaperones BiP and PDI, which are the main effectors of the unfolded protein response. These findings indicate that impaired autophagy leads to slight disturbances in lipid metabolism and general cell proteostasis. However, the ability of insects to fly during forced flight until exhaustion was reduced by 60% after knockdown of RpAtg6 and RpAtg8. This change was accompanied by TAG and protein increases as well as decreased ATP levels in the fat body and flight muscle, indicating that autophagy during digestion, i.e., under fed conditions, is necessary to sustain high-performance activity.

ABSTRACT

INTRODUCTION: Checkpoint inhibitors (CPI) are widely used across different tumour types in older cancer patients. The ELDERS study investigated primarily the safety of CPI in older patients, and secondarily its impact on health-related quality of life (HRQoL), comparing older and younger patients. Here we describe the results from its secondary aim. MATERIALS AND METHODS: This was an observational, mixed methods study, consisting of questionnaires and qualitative interviews. Patients completed the EORTC QLQ-C30 at baseline and at three-monthly reviews (up to four over the planned 12 months on study). RESULTS: One hundred and forty patients, 70 in each age cohort (older: ≥70 years of age, younger: <70 years of age), were recruited. Twenty-four patients, 12 in each age cohort, were interviewed. The mean baseline EORTC QLQ-C30 score was 65/100 for both cohorts combined, and the score for the full QLQ-C30 assessment was 78/100 and 75/100 for older and younger, respectively. The physical functioning score was the only subscale to change significantly between baseline and the first and second reviews (p = 0.03 and 0.04, respectively), resulting from some improvement in the mean score (from baseline) within the younger cohort and some decline within the older cohort. However, when focusing on each cohort separately, the change over time was not statistically significant for either. Two main themes from the interviews were 'expectations' (thoughts about treatment before commencing) and 'experience' (lived experience during treatment). DISCUSSION: Quantitatively, there was no difference in the effect of CPIs on HRQoL between the cohorts, although qualitative data from interviews suggested that there were some experiential differences. People in the older cohort were less likely to seek additional information about CPIs and were more likely to report side effects. In terms of both 'expectations' and 'experience,' the older cohort was a heterogenous group, highlighting that an individualised approach is needed when supporting this group. This study shows that older patients can be reassured that immunotherapy is unlikely to negatively impact their HRQoL more than younger patients, and it should be considered a viable treatment option.

ABSTRACT

OBJECTIVE: To assess the effect of different front-of-package (FOPL) schemes on the objective understanding of the nutritional content and intention to purchase products, in Panama. DESIGN: Single-blinded multi-arm parallel-group randomised controlled trial. SETTING: Supermarkets across Panama. Participants were exposed to two-dimensional images of 15 mock-up products presented at random and balanced orders. Participants assigned to the intervention groups were exposed to mock-ups featuring one FOPL scheme: black octagonal warning labels (OWL), traffic-light labelling (TFL), or guideline daily amounts (GDA). Control group was not exposed to any FOPL scheme. PARTICIPANTS: Adult supermarket shoppers (n=1200). Participants were blinded to group assignment. RESULTS: Similar number of participants were randomised to and analysed in each group: OWL (n=300), TFL (n=300), GDA (n=300), and control (n=300). The odds for choosing to purchase the least harmful or none of the options more often was the highest in the OWL group. Compared to the control group, two times higher in the OWL group (OR 2·13, 95% confidence interval 1·60-2·84), and 57% higher in the TFL (1·57, 1·40-2·56), with no changes in the GDA (0·97, 0·73-1·29). OWL also resulted in the highest odds for correctly identifying the least harmful option, and for correctly identifying a product with excessive amounts of sugars, sodium and/or saturated fats. CONCLUSIONS: OWL performed best in helping shoppers to correctly identify when a product contained excessive amounts of nutrients of concern, to correctly identify the least harmful option, and to decide to purchase the least harmful or none of the options, more often.

ABSTRACT

Noncommunicable diseases (NCDs) are the main cause of death globally (70%) and in the Region of the Americas (80%), and poor diets are a leading driver of NCDs. In response, the Pan American Health Organization (PAHO)/World Health Organization (WHO) introduced a set of evidence-based regulatory measures to help countries improve diets through the reduced consumption of processed and ultra-processed foods. This paper aims to describe the needs of and propose actions for key actors to advance these measures. A workshop was designed to assess member states' regulatory capacity. A thematic analysis was conducted to analyze regional needs, successes and challenges. Thereafter, the Government Capacity-Building Framework for the prevention and control of NCDs was used to examine findings. The findings were organized in two sets: (i) PAHO/WHO actions to support member states and (ii) key actors' actions to advance regulatory policies. The results show notable regulatory progress across the Region of the Americas. However, progress differs between countries, with opportunities to strengthen measures in most countries, mainly in conflict of interest management. The results identified important actions to strengthen the regulatory capacity of PAHO/WHO member states. To maximize momentum for these actions, timelines must be identified, and political commitment can be boosted by applying human rights-based and food system-wide approaches.

ABSTRACT

The innate immune system, a cornerstone for organismal resilience against environmental and microbial insults, is highly conserved across the evolutionary spectrum, underpinning its pivotal role in maintaining homeostasis and ensuring survival. This review explores the evolutionary parallels between mammalian and insect innate immune systems, illuminating how investigations into these disparate immune landscapes have been reciprocally enlightening. We further delve into how advancements in mammalian immunology have enriched our understanding of insect immune responses, highlighting the intertwined evolutionary narratives and the shared molecular lexicon of immunity across these organisms. Therefore, this review posits a holistic understanding of innate immune mechanisms, including immunometabolism, autophagy and cell death. The examination of how emerging insights into mammalian and vertebrate immunity inform our understanding of insect immune responses and their implications for vector-borne disease transmission showcases the imperative for a nuanced comprehension of innate immunity's evolutionary tale. This understanding is quintessential for harnessing innate immune mechanisms' potential in devising innovative disease mitigation strategies and promoting organismal health across the animal kingdom.

ABSTRACT

PURPOSE: Electronic patient-reported outcome measures (ePROMs) are digitalized health questionnaires used to gauge patients' subjective experience of health and disease. They are becoming prevalent in cancer care and have been linked to a host of benefits including improved survival. MyChristie-MyHealth is the ePROM established at the Christie NHS Foundation Trust in 2019. We conducted an evaluation of this service to understand user experiences, as well as strategies to improve its functioning. METHODS: Data collection: Patients who had opted never to complete MyChristie-MyHealth (n = 87), and those who had completed at least one (n = 87) were identified. Demographic data included age, sex, ethnicity, postcode, diagnosis, treatment intent, and trial status. Semistructured interviews were held with noncompleters (n = 30) and completers (n = 31) of MyChristie-MyHealth, as well as clinician users (n = 6), covering themes such as accessibility, acceptability and usefulness, and open discourse on ways in which the service could be improved. RESULTS: Noncompleters of MyChristie-MyHealth were older (median age 72 v 66 years, P = .005), receiving treatment with curative rather than palliative intent (odds ratio [OR], 1.45; P = .045), and less likely to be enrolled on a clinical trial (OR, 0.531; P = .011). They were less likely to own a smartphone (33% v 97%) or have reliable Internet access (45% v 100%). Satisfaction with MyChristie-MyHealth was high in both groups: 93% (n = 29) of completers and 87% (n = 26) noncompleters felt generally happy to complete. Completers of MyChristie-MyHealth wanted their results to be acknowledged by their clinicians. Clinicians wanted results to be displayed in a more user-friendly way. CONCLUSION: We have broadly characterized noncompleters of the Christie ePROM to identify those in need of extra support or encouragement in the clinic. An action plan resulting from this review has been compiled and will inform the future development of MyChristie-MyHealth.

ABSTRACT

International investment agreements (IIAs) promote foreign investment. However, they can undermine crucial health programs, creating a dilemma for governments between corporate and public health interests. For this reason, including clauses that safeguard health has become an essential practice in IIAs. According to the current literature, some countries have played a pivotal role in leading this inclusion, while others follow the former ones. However, the existing literature needs a unique approach that can quantify the influence strength of a country in disseminating clauses that explicitly mention health provisions to others. Following an NLP (Natural Language Processing)-based text similarity analysis of Bilateral Investment Treaties (BITs), this study proposes a metric, 'Influence' (INF), which provides insights into the role of different countries or regions in the propagation of IIA texts among BITs. We demonstrate a comprehensive application of this metric using a large agreement dataset. Our findings from this application corroborate the evidence in the current literature, supporting the validity of the proposed metric. According to the INF, Germany, Canada, and Brazil emerged as the most influential players in defensive, neutral, and offensive health mentions, respectively. These countries wield substantial bargaining power in international investment law and policy, and their innovative approaches to BITs set a path for others to follow. These countries provide crucial insights into the direction and sources of influence of international investment regulations to safeguard health. The proposed metric holds substantial usage for policymakers and investors. This can help them identify vital global countries in IIA text dissemination and create new policy guidelines to safeguard health while balancing economic development and public health protection. A software tool based on the proposed INF measure can be found at https://inftool.com/.

ABSTRACT

Immune checkpoint inhibitors (ICIs) became a treatment option in most tumor types and improved survival in patients with cancer in the last decade. Older patients with cancer are underrepresented in the pivotal clinical trials with ICIs. Older patients with cancer often have significant comorbidities and geriatric syndromes like frailty, which can complicate cancer care and treatment decisions. Frailty is among the most prevalent geriatric syndromes in patients with cancer and could lead to inferior survival and a higher risk of complications in patients treated with chemotherapy. However, the effect of frailty on the efficacy and safety of ICIs is understudied. This review focuses on the available evidence regarding the association between frailty and ICI efficacy and safety. Although the survival benefits of ICIs have generally been shown to be independent of age, the available real-world data has generally suggested higher rates of immune-related adverse events (irAEs) and treatment discontinuation in older patients. While international organizations recommend conducting a comprehensive geriatric assessment CGA to assess and address frailty before the start of anti-cancer therapies, an Eastern Cooperative Oncology Group (ECOG) performance status of 2 or higher is frequently used in clinical practice as synonymous with frailty, albeit with significant limitations. The available data has generally demonstrated diminished ICI efficacy in patients with an ECOG 2 or higher compared to patients with better performance status, while the incidence of high-grade irAEs were similar. Whilst evidence regarding outcomes with ICI in older patients and in those with sub-optimal performance status is growing, there is very limited data specifically evaluating the role of frailty with ICIs. These studies found a shortened overall survival, yet no evidence of a lower response rate to ICIs. These patients experienced more AEs, but they did not necessarily have a higher incidence of irAEs.

ABSTRACT

Innate immunity is present in all animals. In this review, we explore the main conserved mechanisms of recognition and innate immune responses among animals. In this sense, we discuss the receptors, critical for binding to pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs); the downstream signaling proteins; and transcription factors that govern immune responses. We also highlight conserved inflammatory mediators that are induced after the recognition of DAMPs and PAMPs. At last, we discuss the mechanisms that are involved in the regulation and/or generation of reactive oxygen species (ROS), influencing immune responses, like heme-oxygenases (HOs).

ABSTRACT

BACKGROUND: The high prevalence of metabolic syndrome in low- and middle-income countries is linked to an increase in Western diet consumption, characterized by a high intake of processed foods, which impacts the levels of blood sugar and lipids, hormones, and cytokines. Hematophagous insect vectors, such as the yellow fever mosquito Aedes aegypti, rely on blood meals for reproduction and development and are therefore exposed to the components of blood plasma. However, the impact of the alteration of blood composition due to malnutrition and metabolic conditions on mosquito biology remains understudied. METHODS: In this study, we investigated the impact of whole-blood alterations resulting from a Western-type diet on the biology of Ae. aegypti. We kept C57Bl6/J mice on a high-fat, high-sucrose (HFHS) diet for 20 weeks and followed biological parameters, including plasma insulin and lipid levels, insulin tolerance, and weight gain, to validate the development of metabolic syndrome. We further allowed Ae. aegypti mosquitoes to feed on mice and tracked how altered host blood composition modulated parameters of vector capacity. RESULTS: Our findings identified that HFHS-fed mice resulted in reduced mosquito longevity and increased fecundity upon mosquito feeding, which correlated with alteration in the gene expression profile of nutrient sensing and physiological and metabolic markers as studied up to several days after blood ingestion. CONCLUSIONS: Our study provides new insights into the overall effect of alterations of blood components on mosquito biology and its implications for the transmission of infectious diseases in conditions where the frequency of Western diet-induced metabolic syndromes is becoming more frequent. These findings highlight the importance of addressing metabolic health to further understand the spread of mosquito-borne illnesses in endemic areas.

ABSTRACT

INTRODUCTION: Ultra-processed food products (UPF) have been related to chronic diseases (CD). Public health politics has been establishing strategies to decrease the consumption of these products in the country. OBJECTIVES: i) To assess the trend of the consumption of UPF between 2005 and 2015. (ii) its association with sociodemographic factors and the overall dietary content of nutrients related to CD in 2015. (iii) to estimate the Population Attributable Fraction of unhealthy nutrient intake in Colombia in 2015 due to ultra-processed food consumption. METHODS: We used data from the first (2005) and the last (2015) National Surveys of the Nutritional Status in Colombia. Food consumption was assessed using a 24-hour food recall. The NOVA classification classified the food items according to the extent and purpose of industrial processing. RESULTS: The consumption of processed and UPF increased in Colombia between 2005 and 2015. In 2015, no significant differences were found in the consumption of UPF between men and women but significant differences by age, wealth index, area of residence, and ethnicity (p<0.001). A significant positive association was found between the dietary share of UPF and the content of CD-related nutrients such as free sugars, total fats, saturated fats, trans-fats, and sodium. The prevalence of excessive intake of all CD-related nutrients (according to WHO recommendations) increased across quintiles of the dietary share of UPF. With the reduction of UPF consumption to the level seen among the 20% lowest consumers [1.0% (0-4.5%) of the total energy from UPF], the prevalence of excessive nutrient intake was almost three-fourths lower for trans fats; around one third lower for free sugar and saturated fats, 26% lower for sodium and 15% lower for total fat. CONCLUSIONS: In Colombia, the increasing trend in the consumption of UPF is associated with increasing intake of CD-related nutrients. Thus, reducing the consumption of UPF is a potentially effective way to achieve the nutritional goals of the WHO for the prevention of CD.

ABSTRACT

Introduction: Quality of life is a multifaceted construct that depends on the person's subjective perception; however, some studies have shown self-efficacy and cognition with possible indicators of this positive perception of quality of life in people. Objective: Examined prediction of Quality of Life (QL) and its domains according to self-efficacy, physical activity (PA) and cognition among elderly people attending public Open Universities for the elderly in the State of Paraná, Brazil. Method: Cross-sectional descriptive correlational study with a sample of 277 elderly. Questionnaires used: Sociodemographic, WHOQOL-BREF and WHOQOL-OLD, IPAQ, General Perceived Self-Efficacy Scale and Addenbrooke's Cognitive Examination. Statistical: Descriptive and inferential analysis (correlation and multiple linear regression), significancep < .05. Results: The mean age was 67.60 (SD=6.65). Self-efficacy was related to QOL and to all domains. PA correlated with general QOL and the Psychological and Social domains. Cognition was correlated with general QOL and five other domains (Physical, Psychological, Social, Environmental, Sensory functioning, Past/Present/ Future Activities). Self-efficacy, PA and Cognition can explain 10% of the general QOL, and 14% of the Environmental domain. The specific QOL and its domains had 10% of explanation. Conclusion: QOL can be explained by the constructs self-efficacy, cognition and PA.

Objetivo: se examinó la predicción de la calidad de vida (CV) y sus dominios según la autoeficacia, la actividad física (AF) y la cognición entre ancianos que asisten a Universidad Abierta para Adultos Mayores en el Estado de Paraná, Brasil. Método: estudio transversal descriptivo correlacional con una muestra de 277 ancianos. Cuestionarios utilizados: sociodemográfico, WHOQOL-BREF y WHOQOL-OLD, IPAQ, Escala de Autoeficacia Percibida General y Examen Cognitivo de Addenbrooke. Estadística: análisis descriptivo e inferencial (correlación y regresión lineal múltiple), significancia p < .05. Resultados: la edad media fue de 67.60 (DE=6.65). La autoeficacia se relacionó con la calidad de vida y con todos los dominios. AF se correlacionó con la CV general y los dominios psicológico y social. La cognición se correlacionó con la calidad de vida general y otros cinco dominios (funcionamiento físico, psicológico, social, ambiental, sensorial, actividades pasadas/presentes/futuras). Autoeficacia, AF y cognición pueden explicar el 10% de la CV general y el 14% del dominio ambiental. La CV específica y sus dominios tuvieron 10% de explicación. Conclusión: la CV puede ser explicada por los constructos autoeficacia, cognición y AF.

ABSTRACT

Cancer is a disease associated with ageing. Managing cancer in older adults may prove challenging owing to pre-existing frailty, comorbidity, and wider holistic needs, as well as the unclear benefits and harms of standard treatment options. With the ongoing advances in oncology and the increasing complexity of treating older adults with cancer, the geriatric oncology field must be a priority for healthcare systems in education, research, and clinical practice. However, geriatric oncology is currently not formally taught in undergraduate education or postgraduate training programmes in the United Kingdom (UK). In this commentary, we outline the landscape of geriatric oncology undergraduate education and postgraduate training for UK doctors. We highlight current challenges and opportunities and provide practical recommendations for better preparing the medical workforce to meet the needs of the growing population of older adults with cancer. This includes key outcomes to be considered for inclusion within undergraduate and postgraduate curricula.

ABSTRACT

Oligomerization of proteins and their modified forms (proteoforms) produces functional protein complexes 1,2. Complexoforms are complexes that consist of the same set of proteins with different proteoforms 3. The ability to characterize these assemblies within cells is critical to understanding the molecular mechanisms involved in disease and to designing effective drugs. An outstanding biological question is how proteoforms drive function and oligomerization of complexoforms. However, tools to define endogenous proteoform-proteoform/ligand interactions are scarce 4. Here, we present a native top-down proteomics (nTDP) strategy that combines size-exclusion chromatography, nano liquid-chromatography in direct infusion mode, field asymmetric ion mobility spectrometry, and multistage mass spectrometry to identify protein assemblies (≤70 kDa) in breast cancer cells and in cells that overexpress EGFR, a resistance model of estrogen receptor-α (ER-α) targeted therapies. By identifying ~104 complexoforms from 17 protein complexes, our nTDP approach revealed several molecular features of the breast cancer proteome, including EGFR-induced dissociation of nuclear transport factor 2 (NUTF2) assemblies that modulate ER activity. Our findings show that the K4 and K55 posttranslational modification sites discovered with nTDP differentially impact the effects of NUTF2 on the inhibition of the ER signaling pathway. By characterizing endogenous proteoform-proteoform/ligand interactions, we reveal the molecular diversity of complexoforms, which allows us to propose a model for ER drug discovery in the context of designing effective inhibitors to selectively bind and disrupt the actions of targeted ER complexoforms.

ABSTRACT

The fungus Moniliophthora perniciosa secretes protein effectors that manipulate the physiology of the host plant, but few effectors of this fungus have had their functions confirmed. We performed functional characterization of a promising candidate effector of M. perniciosa. The inoculation of rBASIDIN at 4 µmol L-1 in the mesophyll of leaflets of Solanum lycopersicum caused symptoms of shriveling within 6 h without the presence of necrosis. However, when sprayed on the plant at a concentration of 11 µmol L-1, it caused wilting symptoms only 2 h after application, followed by necrosis and cell death at 48 h. rBASIDIN applied to Theobroma cacao leaves at the same concentration caused milder symptoms. rBASIDIN caused hydrogen peroxide production in leaf tissue, damaging the leaf membrane and negatively affecting the photosynthetic rate of Solanum lycopersicum plants. Phylogenetic analysis indicated that BASIDIN has orthologs in other phytopathogenic basidiomycetes. Analysis of the transcripts revealed that BASIDIN and its orthologs are expressed in different fungal species, suggesting that this protein is differentially regulated in these basidiomycetes. Therefore, the results of applying BASIDIN allow the inference that it is an effector of the fungus M. perniciosa, with a strong potential to interfere in the defense system of the host plant.

ABSTRACT

Diet-induced obesity triggers elevation of circulating pro-inflammatory cytokines and acute-phase proteins, including interferons (IFNs). IFNs strongly contribute to low-grade inflammation associated with obesity-related complications, such as nonalcoholic fat liver disease and diabetes. In this study, AG129 mice model (double-knockout strain for IFN α/ß/γ receptors) was fed with a high-fat high-sucrose (HFHS) diet (Western diet) for 20 weeks aiming to understand the impact of IFN receptor ablation on diet-induced obesity, insulin resistance, and nonalcoholic fat liver disease. Mice were responsive to the diet, becoming obese after 20 weeks of HFHS diet which was accompanied by 2-fold increase of white adipose tissues. Moreover, animals developed glucose and insulin intolerance, as well as dysregulation of insulin signaling mediators such as Insulin Receptor Substrate 1 (IRS1), protein kinase B (AKT), and S6 ribosomal protein. Liver increased interstitial cells, and lipid accumulation was also found, presenting augmented fibrotic markers (transforming growth factor beta 1 [Tgfb1], Keratin 18 [Krt18], Vimentin [Vim]), yet lower expression on IFN receptor downstream proteins (Toll-like receptor [TLR] 4, nuclear factor kappa-light-chain-enhancer of activated B cells [NFκB], and cAMP response element-binding protein [CREB]). Thus, IFN receptor ablation promoted effects on NFκB and CREB pathways, with no positive effects on systemic homeostasis in diet-induced obese mice. Therefore, we conclude that IFN receptor signaling is not essential for promoting the complications of diet-induced obesity and thus cannot be correlated with metabolic diseases in a noninfectious condition.

ABSTRACT

BACKGROUND: Front-of-package warning labels (FOPWL) have been adopted in many countries aiming at reducing the consumption of unhealthy food and drink products and have also been considered in Guatemala. The aim of the study is to evaluate the efficacy of FOPWL versus Guidelines for Daily Amount (GDA) on products' healthfulness perception (HP), purchase intention (PI) and the objective understanding of the nutrient content (UNC) in Guatemala. METHODS: Participants (children and adults) (n = 356) were randomly assigned to evaluate either FOPWL or GDA during a crossover cluster randomized experiment in rural and urban areas across 3 phases of exposure. During phase 1, participants evaluated mock-up images of single products (single task) and compared pairs of products within the same food category (comparison task) without any label. In phase 2, participants evaluated labels only (without any product), and during phase 3, they evaluated the same products and questions from phase 1, now depicting the assigned front-of-package label. We generated indicators for single-task questions and scores for comparison tasks, one for each HP, PI and UNC questions. We used intention-to-treat, difference-in-difference regression analysis to test whether exposure to FOPWL was associated with HP, PI and UNC, compared to GDA. We also tested models for children and adults and by area (rural/urban) separately adjusting for sociodemographic variables. RESULTS: In single tasks, FOPWL significantly decreased the PI (ß -18.1, 95%CI -23.3, -12.8; p < 0.001) and the HP (ß -13.2, 95%CI -18.4, -7.9; p < 0.001) of unhealthy food products compared to GDA. In the comparison task, FOPWL significantly increased the UNC (ß 20.4, 95%CI 17.0, 23.9; p < 0.001), improved PI towards healthier choices (OR 4.5, 95%CI 2.9, 7.0 p < 0.001) and HP (OR 5.6, 95%CI 2.8, 11.1; p < 0.001) compared to GDA. Similar results were found in children and adults and in urban and rural settings. CONCLUSIONS: FOPWL reduces products' healthfulness perception and purchase intention, and increases understanding of products' nutrient content compared to GDA.

ABSTRACT

Background: The Spinnaker study evaluated survival outcomes and prognostic factors in patients with advanced non-small-cell lung cancer receiving first-line chemoimmunotherapy in the real world. This sub-analysis assessed the immunotherapy-related adverse effects (irAEs) seen in this cohort, their impact on overall survival (OS) and progression-free survival (PFS), and related clinical factors. Methods: The Spinnaker study was a retrospective multicentre observational cohort study of patients treated with first-line pembrolizumab plus platinum-based chemotherapy in six United Kingdom and one Swiss oncology centres. Data were collected on patient characteristics, survival outcomes, frequency and severity of irAEs, and peripheral immune-inflammatory blood markers, including the neutrophil-to-lymphocyte ratio (NLR) and systemic immune-inflammation index (SII). Results: A total of 308 patients were included; 132 (43%) experienced any grade irAE, 100 (32%) Grade 1-2, and 49 (16%) Grade 3-4 irAEs. The median OS in patients with any grade irAES was significantly longer (17.5 months [95% CI, 13.4-21.6 months]) than those without (10.1 months [95% CI, 8.3-12.0 months]) (p<0.001), either if Grade 1-2 (p=0.003) or Grade 3-4 irAEs (p=0.042). The median PFS in patients with any grade irAEs was significantly longer (10.1 months [95% CI, 9.0-11.2 months]) than those without (6.1 months [95% CI, 5.2-7.1 months]) (p<0.001), either if Grade 1-2 (p=0.011) or Grade 3-4 irAEs (p=0.036). A higher rate of irAEs of any grade and specifically Grade 1-2 irAEs correlated with NLR <4 (p=0.013 and p=0.018), SII <1,440 (p=0.029 ad p=0.039), response to treatment (p=0.001 and p=0.034), a higher rate of treatment discontinuation (p<0.00001 and p=0.041), and the NHS-Lung prognostic classes (p=0.002 and p=0.008). Conclusions: These results confirm survival outcome benefits in patients with irAEs and suggest a higher likelihood of Grade 1-2 irAEs in patients with lower NLR or SII values or according to the NHS-Lung score.

ABSTRACT

BACKGROUND: Cancer and its treatment can have significant impacts on health status, quality of life and functioning of patients. Direct information from patients regarding these aspects can be collected via electronic platforms in the form of electronic Patient Reported Outcome Measures (ePROMs). Research has shown that the use of ePROMS in cancer care leads to improved communication, better symptom control, prolonged survival and a reduction in hospital admissions and emergency department attendance. Acceptability and feasibility of routine ePROM collection has been reported by both patients and clinicians but to date their use has predominantly been limited to clinical trials. MyChristie-MyHealth is an initiative from a UK comprehensive cancer centre The Christie NHS Foundation Trust which incorporates the regular collection of ePROMs into routine cancer care. This study, carried out as part of a service evaluation, explores patient and clinician experiences of using the MyChristie-MyHealth ePROMs service. RESULTS: 100 patients with lung and head and neck cancers completed a Patient Reported Experience questionnaire. All patients reported that MyChristie-MyHealth was easy to understand and, almost all found it timely to complete and easy to follow. Most patients (82%) reported it improved their communication with their oncology team and helped them to feel more involved with their care (88%). A large proportion of clinicians (8/11) felt ePROMs helped communication with their patients and over half (6/10) felt they led to consultations being more patient focused. Clinicians also felt that the use of ePROMs resulted in patients being more engaged in consultations (7/11) and their cancer care in general (5/11). Five clinicians reported that the use of ePROMs altered their clinical decision making. CONCLUSIONS: Regular ePROMs collection as part of routine cancer care is acceptable to both patients and clinicians. Both patients and clinicians feel their use improved communication and increased the feeling of patient involvement with their care. Further work is needed to explore the experiences of patients that did not complete the ePROMs as part of the initiative and to continue to optimize the service for both patients and clinicians.
