RESUMEN

Choline is a vital micronutrient that can be utilized in the formation of betaine and multiple phospholipids. In this study, we aimed to confirm, and expand on previous findings, how choline impacts embryos from the first 7 days of development to affect postnatal phenotype. Bos indicus embryos were cultured in a choline-free medium (termed vehicle) or medium supplemented with 1.8 mM choline Blastocyst-stage embryos were transferred into crossbred recipients. Once born, calves were evaluated at birth, 94 d, 178 d and at weaning (average age = 239 d). Following weaning, all calves were enrolled into a feed efficiency trial before being separated by sex, with males being slaughtered at approximately 580 d of age and females followed until their first pregnancy check. Results confirm that exposure of 1.8 mM choline chloride during the first 7 d of development alters postnatal characteristics of the resultant calves. Calves of both sexes from choline-treated embryos were consistently heavier through weaning and males had heavier testes at 3 mo of age. There were sex-dependent alterations in DNA methylation in whole blood caused by choline treatment. After weaning, feed efficiency was affected by an interaction with sex, with choline calves being more efficient for females and less efficient for males. Calves from choline-treated embryos were heavier, or tended to be heavier, than calves from vehicle embryos at all observations after weaning. Carcass weight was heavier for choline calves and the cross-sectional area of the Longissumus thoracis muscle was increased by choline. Few females became pregnant during the experiment although numerically more choline females were pregnant than vehicle females. Results confirm that exposure of the preimplantation embryo to 1.8 mM choline can alter phenotypes of the resultant calves through the first 19 months after birth.

RESUMEN

BACKGROUND: During recent years, the burden of bureaucracy in clinical research has increased dramatically, adversely impacting the activity of investigators and clinical research teams. Although compliance with the Declaration of Helsinki, the guidelines for Good Clinical Practice (GCP), and other applicable regulations remains unquestionable, their overinterpretation and substitution by the internal operating procedures of sponsors and Contract Research Organizations (CROs) have increased the administrative burden. A survey conducted by the European Society for Medical Oncology (ESMO) Clinical Research Observatory (ECRO) among 940 investigators confirmed that they considered that the administrative burden in clinical research is excessive; that administrative procedures could be reduced without affecting the safety and the rights of the patients and the quality of the data; and that bureaucracy represents an obstacle for clinical research. METHODS: A panel of physicians with extensive experience in clinical research, composed by members of the ECRO and the ESMO Scientific Medical and Public Policy divisions, analyzed clinical trial procedures related to administrative workflow, pharmacovigilance, and medical care. RESULTS: The panel identified situations that generate debate between investigators and sponsors/CROs and selected real clinical scenarios that exemplify such situations. The panel discussed and proposed specific recommendations for those situations, based on GCP. CONCLUSIONS: This initiative aspires to streamline clinical research procedures and to become a platform for discussion among all clinical trial stakeholders, with the aim of promoting the sustainability of clinical research and the care of cancer patients.

RESUMEN

BACKGROUND: Mucosal melanoma is a rare malignancy which represents approximately 1% of all melanomas. It is shown that mucosal melanomas have a different biology and less favourable prognosis than its cutaneous counterpart. OBJECTIVES: Predictive and prognostic factors of survival for mucosal melanoma have not yet been elucidated. The aim of this study was to investigate risk factors affecting the course of mucosal melanoma patients followed in our clinic. METHODS: One hundred and sixty-one patients with mucosal melanoma prospectively documented in the German Central Malignant Melanoma Registry (CMMR) were included in this study. Gender, age, localization, stage at first medical examination, tumour thickness and mutational status were documented. The American Joint Committee on Cancer (AJCC), 7th edition was used to define tumour stage. Kaplan-Meier survival curves were evaluated compared with the log-rank test. Multivariate Cox proportional hazard models were used to identify significant independent prognostic factors. RESULTS: According to the localization, patients were categorized in 44.7% oral-nasal, 28.6% genital, 20.5% anorectal and 6.2% visceral. Genital mucosal melanomas had the most favourable 5-year OS rate (58.6%) followed by visceral (58.3%) and oral-nasal (39.3%). Anorectal melanomas had the worst OS time (median: 21 ± 4.8 months) and 5-year survival rate (22.7%). Patients <60 years had a better survival than the older group (P = 0.013). Tumour stage at the time of the first medical examination was also a significant factor for survival (P = 0.001). Gender and mutational status were found to have no effect on survival. Age (<60 years vs. ≥60 years; HR = 2.1) and stage at first medical examination (Stage I vs. Stage IV; HR = 8.2) are shown to be significant independent prognostic factors on multivariate Cox regression analysis, but not localization. CONCLUSION: In this study, we observed that older age and advanced stage have significant negative effects on the survival of mucosal melanoma. Thus, the AJCC staging system is applicable for mucosal melanoma.

RESUMEN

BACKGROUND: It is known that melanoma can metastasize and recur many years after the first diagnosis. Although predictive and prognostic factors for melanoma are well defined, there is still insufficient information about the factors affecting the recurrence period and the effect of the recurrence time to survival. OBJECTIVES: This study investigates the course of melanoma to show prognostic factors comparing early and late recurrence patients. The main objective is to uncover the effect of the recurrence time on the progression of the disease. METHODS: In this retrospective study, late recurrence (LR) was defined as melanoma recurrence 10 years after the first diagnosis and early recurrence (ER) was defined as recurrence within 10 years. Gender, age, localization of primary tumour, time to first metastasis, survival rates, histological subtype, stage, tumour thickness, invasion level, ulceration and regression of the primary melanoma were documented. Survival curves were evaluated using the Kaplan-Meier and compared with the log-rank test. Multivariate Cox proportional hazard models were used to identify significant independent prognostic factors for melanoma-specific survival (MSS). RESULTS: A total of 1537 melanoma patients were analysed. Early metastasis was developed in 1438 patients (93.6%), and 99 patients (6.4%) developed late metastasis. Late recurrence patients were younger (P < 0.001) and had fewer ulcerated (P = 0.005), fewer head/neck localized (P = 0.009) and thinner (P < 0.001) melanomas than ER patients. The MSS time (mean ± SD) was nearly identical for LR (31 ± 4.4 months 95% CI [22.3-39.7]) and ER (32 ± 1.9 months [28.3-35.7]). Multivariate regression analysis revealed male gender (hazard ratio [HR = 1.4, P < 0.001), truncal tumour localization (HR = 1.7, P < 0.001), tumour thickness (HR = 1.4, P < 0.045) and ulceration (HR = 1.3, P < 0.008) as significant independent prognostic factors for MSS. CONCLUSION: Although ER and LR patients are found to have different clinicopathologic features, the time of the first recurrence after diagnosis do not seem to have an effect on the survival.

RESUMEN

BACKGROUND: Dehydration appears to affect muscle strength and weakness, although its influence on exhaustion remains unclear. The present study aimed to quantify the association between hydration status and exhaustion among older adults. METHODS: A cluster sampling approach was used, representing Portuguese older adults (≥65 years) according to age, sex, education level and region within the Nutrition UP65 cross-sectional study. A 24-h urine sample was collected to estimate free water reserve (FWR), which was categorised into tertiles according to sex. Subjects with incomplete 24-h urine and renal disease were excluded. From a sample size of 1500 subjects, 1143 were eligible. Exhaustion was self-reported according to the Center for Epidemiologic Studies Depression Scale. A logistic regression model was conducted to evaluate the association between FWR and exhaustion. Odds ratios and the respective 95% confidence intervals were calculated by sex and age. RESULTS: Free water reserve median (interquartile range) was 0.52 (0.68) L in women and 0.36 (0.77) L in men. Hypohydration affected 11.6% of women and 25.1% of men, whereas exhaustion was reported by 39.3% of women and 25.1% of men. After adjusting for confounders, women ≥80 years classified in the highest tertile of FWR showed a decreased risk of exhaustion (third tertile: odds ratio = 0.38; 95% confidence interval = 0.15-0.96) compared to women in the lowest FWR tertile. No such significant association was observed in women with <80 years and in men. CONCLUSIONS: These results show an association between worse hydration status and exhaustion in older women, highlighting the need to implement further studies clarifying this association.

RESUMEN

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) is one of the most common types of cancer in the Caucasian population, with an increasing incidence. cSCC is mostly a local invasive disease that can be treated surgically in the majority of the cases. However, in the case of advanced cSCC (acSCC), a multimodality approach also involving systemic therapies needs to be considered. METHODS: One hundred and ninety-five patients diagnosed with acSCC (stages III and IV) treated in our centre between 2011 and 2018 were included. Patient and tumour characteristics along with treatment patterns were documented and analyzed. Descriptive analysis was performed and survival rates were estimated according to Kaplan-Meier and compared with the Log-rank test. Follow-up was defined as the time between diagnosis of advanced disease and last contact or death. All causes of death were considered as events. RESULTS: The median follow-up was 21 months [IQR = (10.0; 21.0)]. The median age at time of advanced disease diagnosis was 78 years [IQR = (72; 84)], with 40.5% of the patients in stage III and 59.5% in stage IV. One hundred and forty-five patients had resectable tumours. In this group the median overall survival (mOS) was 59 months (95% CI: 28.2-89.8), significantly higher than the mOS in patients with inoperable tumour [n = 50; mOS: 19 months (96% CI: 7-31, P <0.0001)]. Patients receiving immunotherapy (n = 20) showed a statistically significant better survival compared to those treated with other systemic therapies (n = 37; mOS not reached vs. mOS: 22 months (95% CI: 6.5-43.5), P = 0.034). For patients without systemic therapy, a combination of surgery and radiotherapy provided better outcomes compared to radiotherapy alone or best supportive care (P <0.001). CONCLUSION: Surgical complete resection should be the first therapeutic option for patients with acSCC. For patients with inoperable tumour, first-line immunotherapy should be preferably considered.

RESUMEN

OBJECTIVES: To characterize incidence and mortality trends of cutaneous melanoma (CM) in Germany to extrapolate these data until 2030. METHODS: We evaluated data from the Centre for Cancer Registry Data (1999-2012) and from the Saarland Cancer Registry (1970-2012). Age-standardized (according to the European Standard Population, WHO 1976) incidence and mortality rates [age-standardized incidence rates (ASIRs) and age-standardized mortality rates (ASMRs)] and crude incidence and mortality rates [crude incidence rates (CIRs) and crude mortality rates (CMRs)] were analysed. RESULTS: In entire Germany, ASIRs increased by 55% to 19.2 and CIRs by 77% to 26.0 new cases per 100 000 from 1999 to 2012. ASMRs remained stable, whereas CMR increased by 58% to 4.1 for males and by 30% to 3.0 for females per 100 000. In the Federal State of Saarland, ASIRs increased more than four-fold to 13.1, CIRs increased six-seven fold to 18.5/100 000 from 1970 to 2012. In the same period, ASMRs increased three-fold in males and two-fold in females to 2.5 and 1.6, whereas CMRs increased 5.5-fold in males and 3.5-fold in females to 3.9 and 3.2/100 000, mainly caused by steep increases of CIRs and CMRs in age groups ≥60 years. Projected CIRs will rise to 44-46 for males and 38-40 for females in 2030. Steepest increases were extrapolated for patients ≥60 years, especially for males, but are also expected for age groups of 40-59 years. In contrast, CIRs are anticipated to stabilize for subjects <40 years. CONCLUSIONS: There is a constant increase in incidence and mortality rates for CM in Germany. As the German population is ageing and the current population has already accumulated high levels of UV exposure, a further increase in melanoma incidence is projected for the future without signs of levelling-off.

RESUMEN

Aflatoxin is a potent carcinogen often found in animal feedstuffs. Although it reportedly impairs development of the preimplantation pig embryo, it is not known whether it adversely affects development of the preimplantation bovine embryo. We conducted 3 experiments to investigate this possibility and determine whether deleterious effects of aflatoxin were caused by increased production of reactive oxygen species (ROS). Experiments were conducted with embryos produced in vitro and cultured after fertilization with various concentrations of aflatoxin. For experiment 1, embryos were treated with 0 (control), 40, 400, or 4,000 µg/L of aflatoxin B1 (AFB1). Treatment at all concentrations of AFB1 tended to reduce cleavage rate, with the 2 highest concentrations having significant effects. As compared with the control, 40 µg/L AFB1 reduced the percentage of oocytes becoming blastocysts and the percentage of cleaved embryos becoming blastocysts (19.7 vs. 8.1% and 30.3 vs. 14.3%, respectively). Complete inhibition of blastocyst formation occurred at concentrations of 400 and 4,000 µg/L of AFB1. Experiments 2 and 3 involved a 2 × 2 factorial design with effects of AFB1 (0 and 40 µg/L), the antioxidant Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid, a water-soluble analog of vitamin E; 0 and 5 µM), and their interaction on production of ROS in putative zygotes (experiment 2) and development to the blastocyst stage (experiment 3). Production of ROS was increased by AFB1, and this effect was reversed by Trolox. However, Trolox did not prevent the reduction in development to the blastocyst stage caused by AFB1. Thus, the anti-developmental effects of AFB1 are not caused solely by increased ROS production. Rather, other underlying mechanisms exist for the adverse effects of aflatoxin on embryonic development. Overall, results indicate the potential for feeding aflatoxin-contaminated feed to cause embryonic loss in cattle.

RESUMEN

OBJECTIVES: The prevalence of DYT1 (mutation in TOR1A) and DYT6 (mutation in THAP1) may vary in different populations, which can have important implications in clinical investigation. Our goal was to characterize patients with inherited and isolated dystonia and determine the frequency of mutations responsible for DYT1 and DYT6 in Brazilian patients. METHODS: Two movement disorder specialists examined 78 patients with idiopathic isolated dystonia using a standardized questionnaire, before sequencing TOR1A and THAP1 genes. RESULTS: Clinically, our cohort was similar to those described in the international literature. Molecular studies of 68 subjects revealed only one potentially deleterious variant in THAP1 (1/68 patients, 1.47%). This was a novel 10-bp deletion at the end of exon 1, g.5308_5317del (ng_011837.1), which is predicted to create an alternative splicing and the insertion of a premature stop codon. Although we did not observe any potentially deleterious mutations in TOR1A, we found the missense variant rs1801968 (TOR1A p.D216H), previously reported as either a modifier of dystonia phenotype or a predisposing factor for dystonia. However, we did not identify any phenotypic impact related to the missense variant rs1801968 (P = 0.3387). CONCLUSIONS: Although clinically similar to most cohorts with dystonia worldwide, the classical mutation (c.907_909delGAG) in TOR1A (causing DYT1) is absent in our patients. However, we found a potentially deleterious THAP1 mutation not previously reported. In addition, we found no association of rs1801968 with dystonia.

RESUMEN

BACKGROUND: Hand grip strength (HGS) is used for the diagnosis of sarcopenia and frailty. Several factors have been shown to influence HGS values during measurement. Therefore, variations in the protocols used to assess HGS, as part of the diagnosis of sarcopenia and frailty, may lead to the identification of different individuals with low HGS, introducing bias. The aim of this systematic review is to gather all the relevant studies that measured HGS to diagnose sarcopenia and frailty and to identify the differences between the protocols used. METHODS: A systematic review was carried out following the recommendations of The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. PubMed and Web of Science were systematically searched, until August 16, 2016. The evidence regarding HGS measurement protocols used to diagnose sarcopenia and frailty was summarised and the most recent protocols regarding the procedure were compared. RESULTS: From the described search 4393 articles were identified. Seventy-two studies were included in this systematic review, in which 37 referred to sarcopenia articles, 33 to frailty and two evaluated both conditions. Most studies presented limited information regarding the protocols used. CONCLUSIONS: The majority of the studies included did not describe a complete procedure of HGS measurement. The high heterogeneity between the protocols used, in sarcopenia and frailty studies, create an enormous difficulty in drawing comparative conclusions among them.

RESUMEN

BACKGROUND: Undernutrition is associated with higher hospitalisation costs. The present study aims (i) to explore whether undernutrition status at hospital admission, as evaluated by different screening and diagnostic tools, can predict patient's hospitalisation costs and (ii) to provide an updated economic analysis of undernutrition burden. METHODS: A prospective study was conducted in a university hospital. Participants' (n = 637) nutritional risk was evaluated within 72 h of admission using the Nutritional Risk Screening (NRS-2002) and the Malnutrition Universal Screening Tool ('MUST'). Undernutrition status was determined by Academy of Nutrition and Dietetics (AND) and American Society for Parenteral and Enteral Nutrition (ASPEN) recommended clinical characteristics and by the Patient Generated Subjective Global Assessment (PG-SGA). The hospitalisation cost was calculated for each inpatient using the diagnosis-related group system. Multivariable linear regression analysis was conducted to identify predictors of hospitalisation costs via percentage deviation from the mean cost, after adjustment for patients' characteristics and comorbidities. RESULTS: Undernutrition risk according to NRS-2002 and high undernutrition risk according to 'MUST' increased patient's costs, respectively, by 21.1% [95% confidence interval (CI) = 9.0-33.2%] and 28.8% (95% CI = 13.7-39.9%). Severe undernutrition by AND-ASPEN recommended clinical characteristics and by PG-SGA was also associated with higher hospitalisation costs, respectively 19.4% (95% CI = 7.3-31.5%) and 27.5% (95% CI = 14.0-41.1%). The cost of a nutritionally-at-risk or undernourished patient is between €416 (95% CI = €156-675) and €617 (95% CI = €293-855) higher than the average of the respective diagnosis-related group. CONCLUSIONS: Undernutrition is a predictor of hospitalisation costs, increasing costs by between 19% and 29%. Undernutrition screening tools have an ability for predicting hospitalisation costs similar to that of diagnostic tools. An updated analysis of undernutrition associated costs was provided, highlighting the economic burden of undernutrition.

RESUMEN

BACKGROUND: Standards for anthropometrical assessment define that measurements must be carried out with the subject in the standing position, although this is not always possible. The effect of body position on girth measurement has not been evaluated, even though this issue is clinically relevant because it may bias nutritional assessment results. The present study aimed to evaluate the effect of body position and symmetry on girth measurement. METHODS: A cross-sectional study was conducted on 102 older adults aged ≥65 years from care homes and tertiary hospitals. Right and left arm, waist, hip mid-thigh and calf girths were obtained with the subject standing or in the supine position. Mini-Nutritional Assessment Short-Form (MNA-SF) score and reference data percentiles (NHANES IV) misclassification according to girths assessed in the supine position was evaluated. RESULTS: A high intraclass correlation coefficient (ICC > 0.97) and quartiles agreement (k > 0.89) were found between girth measurements conducted on participants in the standing and supine positions. According to MNA-SF, 23.5% of the participants were undernourished and 51% were at risk of undernutrition. A high agreement between MNA-SF score using calf circumference measured on standing or supine position was found (k = 0.96). A relevant agreement for NHANES IV girth percentiles by sex and age was also found (ICC > 0.89). CONCLUSIONS: Agreement between girth measurements on standing and supine positions among older adults is high and differences do not have any clinically relevant impact on MNA-SF classification and reference data percentiles.

RESUMEN

BACKGROUND: Cancer is a global public health problem, requiring efficient health system investments to deliver sustainable impact on population health. Access to medicines is a critical component of health systems, having a crucial role in delivering therapeutic benefits. Since 1977, the World Health Organization (WHO) has published a Model List of Essential Medicines (EML) that includes key health interventions for the prevention and control of conditions of public health relevance. Essential medicines are selected for inclusion in the EML based on the evidence of efficacy, safety, therapeutic value, and the potential to impact population health. With the rapid changes in the therapeutic landscape of cancer treatment with new medicine approvals, there is a critical need to select and prioritise specific cancer interventions based on their intrinsic value. MATERIALS AND METHODS: The European Society for Medical Oncology (ESMO) has developed a decisional methodology based on a threshold with a minimum set of technical specifications and a consensus-based procedure for decisions to select candidate cancer medicines to be submitted to the WHO for consideration for the WHO EML. RESULTS: ESMO recognises the WHO EML as an important reference guide for medicines that all countries should include in their national EMLs. Cancer medicines on the WHO EML are used in the treatment of the majority of cancers, and are recommended in the evidence-based ESMO Clinical Practice Guidelines that medical oncologists use to treat patients. ESMO's submissions to the WHO EML in 2019 and 2021 and their respective outcomes are presented in the manuscript. CONCLUSION: Due to the rising costs associated with newly available therapies, structured, reproducible, and field-tested tools to evaluate the added clinical benefit from these therapies need to be implemented in pre-selecting potential candidate medicines to be included in the WHO EML. ESMO is proud to collaborate closely with WHO on this important global public health initiative.

RESUMEN

INTRODUCTION: Off-label use of medicines is generally discouraged. However, several off-patent, low-cost cancer medicines remain off-label for indications in which they are commonly used in daily practice, supported by high-level evidence based on results of phase III clinical trials. This discrepancy may generate prescription and reimbursement obstacles as well as impaired access to established therapies. METHODS: A list of cancer medicines that remain off-label in specific indications despite the presence of high-level evidence was generated and subjected to European Society for Medical Oncology (ESMO) expert peer review to assess for accountability of reasonableness. These medicines were then surveyed on approval procedures and workflow impact. The most illustrative examples of these medicines were reviewed by experts from the European Medicines Agency to ascertain the apparent robustness of the supporting phase III trial evidence from a regulatory perspective. RESULTS: A total of 47 ESMO experts reviewed 17 cancer medicines commonly used off-label in six disease groups. Overall, high levels of agreement were recorded on the off-label status and the high quality of data supporting the efficacy in the off-label indications, often achieving high ESMO-Magnitude of Clinical Benefit Scale (ESMO-MCBS) scores. When prescribing these medicines, 51% of the reviewers had to implement a time-consuming process associated with additional workload, in the presence of litigation risks and patient anxiety. Finally, the informal regulatory expert review identified only 2 out of 18 (11%) studies with significant limitations that would be difficult to overcome in the context of a potential marketing authorisation application without additional studies. CONCLUSIONS: We highlight the common use of off-patent essential cancer medicines in indications that remain off-label despite solid supporting data as well as generate evidence on the adverse impact on patient access and clinic workflows. In the current regulatory framework, incentives to promote the extension of indications of off-patent cancer medicines are needed for all stakeholders.

RESUMEN

Donkeys are a public health concern in the Northeast region of Brazil, with thousands of stray animals. Orchiectomy is an important population control measure; however, the long postoperative period with daily treatment of open wounds in the scrotum makes it difficult to perform a large number of castrations in sheltering centers. We evaluate a novel surgical procedure for orchiectomy in donkeys using parascrotal access. Twelve donkeys were used, divided into two groups: I - submitted to orchiectomy through parascrotal surgical access (novel procedure), and II - submitted to orchiectomy through scrotal access (conventional). Postoperative evaluations consisted of a macroscopic evaluation of the surgical wound (bleeding and intensity of edema), hematological parameters, and peritoneal fluid, which occurred in both groups at the moments (M): M0 - before the surgical procedure. The others moments occurred after surgery: M12 (twelve hours); M24 (twenty-four hours); M48 (forty-eight hours); M72 (seventy-two hours); M8D (eight days); and M16D (sixteen days). The surgical techniques did not generate an important systemic inflammatory response to the point detected by the leukogram, fibrinogen dosage, and peritoneal fluid. The parascrotal technique required long surgery but promoted less bleeding, less edema, and faster healing. The techniques used did not promote sufficient systemic inflammation to alter the number of leukocytes and the fibrinogen concentration; however, evaluation of the peritoneal fluid proved to be important for evaluating inflammatory processes involving the scrotum and inguinal canal. We describe a novel surgical procedure for orchiectomy in Donkeys using a parascrotal access that promoted less risk of bleeding, shorter period of edema, and healing time, but required longer surgery time.

RESUMEN

BACKGROUND: COVID-19 has had a significant impact on the well-being and job performance of oncology professionals globally. The European Society for Medical Oncology (ESMO) Resilience Task Force collaboration set out to investigate and monitor well-being since COVID-19 in relation to work, lifestyle and support factors in oncology professionals 1 year on since the start of the pandemic. METHODS: An online, anonymous survey was conducted in February/March 2021 (Survey III). Key outcome variables included risk of poor well-being or distress (expanded Well-Being Index), feeling burnout (single item from expanded Well-Being Index), and job performance since COVID-19. Longitudinal analysis of responses to the series of three surveys since COVID-19 was carried out, and responses to job demands and resources questions were interrogated. SPSS V.26.0/V.27.0 and GraphPad Prism V9.0 were used for statistical analyses. RESULTS: Responses from 1269 participants from 104 countries were analysed in Survey III: 55% (n = 699/1269) female, 54% (n = 686/1269) >40 years, and 69% (n = 852/1230) of white ethnicity. There continues to be an increased risk of poor well-being or distress (n = 464/1169, 40%) and feeling burnout (n = 660/1169, 57%) compared with Survey I (25% and 38% respectively, P < 0.0001), despite improved job performance. Compared with the initial period of the pandemic, more participants report feeling overwhelmed with workload (45% versus 29%, P < 0.0001). There remain concerns about the negative impact of the pandemic on career development/training (43%), job security (37%). and international fellowship opportunities (76%). Alarmingly, 25% (n = 266/1086) are considering changing their future career with 38% (n = 100/266) contemplating leaving the profession. CONCLUSION: Oncology professionals continue to face increased job demands. There is now significant concern regarding potential attrition in the oncology workforce. National and international stakeholders must act immediately and work closely with oncology professionals to draw up future-proof recovery plans.

RESUMEN

BACKGROUND & AIMS: Undernutrition screening is the starting point for high-quality nutrition care. In Portugal, the systematic nutritional risk assessment became mandatory for every inpatient in hospitals of the National Health System in 2019. The aims of this study were to describe the country's nutritional risk prevalence of hospitalized patients, and the experience of implementing a systematic undernutrition screening method, including time trends, barriers, and facilitators. METHODS: This research was carried out in Portuguese Public Hospitals (n = 49) and included both the analysis of data from health information systems between January 2019 and December 2020 and from an online survey. The performance indicators are described for 38 hospitals that use the SClinico electronic health records software provided by the Ministry of Health. The Nutritional Risk Screening 2002 (NRS 2002) was applied to adult patients and the STRONGkids to paediatric patients. In order to assess barriers and facilitators the online survey was applied to all public hospitals (n = 49), including Hospital Centres and Local Health Units. RESULTS: In 2020, 25.5% of the screened patients were nutritionally at risk. There was a significant increase in the proportion of patients screened from the pre- (10.6 ± 1.9%) to the post-adaptation period of the electronic health record (23.3 ± 4.8%, July-December 2019, and 25.4 ± 2.2%, January-June 2020) (p < 0.001). Data from 41 Hospital Centres and Local Health Units (84%) were obtained from the online survey. The major barriers identified were the lack of human resources (89.7%) and equipment (41.0%), as well as insufficient knowledge about the role of undernutrition screening (35.9%). The most-reported facilitators were the integration of undernutrition screening to electronic health records (22.2%) and good multidisciplinary articulation (36.1%). CONCLUSION: The high prevalence of nutritional risk justifies the mandatory nutritional screening, which leads to the improvement of the quality of hospital care. However, local and national efforts are warranted to adapt nutritional screening policies to local conditions and to increase and improve its implementation.
