RESUMO
BACKGROUND: Surgery plays a key role in the multi-disciplinary cancer care pathway. Nearly 80% of patients with solid tumors will require surgical intervention during the course of their disease. Unfortunately, the vast majority of these patients do not have access to safe, timely, high-quality, and affordable cancer surgical care. The first Lancet Oncology Commission on Global Cancer Surgery shone a light on this grave situation and outlined some strategies to address them. The second Lancet Oncology Commission on Global Cancer Surgery (TLO- II) was conceived to continue the work of its predecessor by developing a roadmap of practical solutions to propel improvements in cancer surgical care globally. METHODS: The Commission was developed by involving approximately 50 cancer care leaders and experts from different parts of the world to ensure diversity of input and global applicability. RESULTS: The Commission identified nine solutional domains that are considered essential to deliver safe, timely, high-quality, and affordable cancer surgical care. These nine domains were further refined to develop solutions specific to each of the six World Health Organization regions. Based on the above solutions, we developed eight action items that are intended to propel improvements in cancer surgical care on the global stage. CONCLUSIONS: The second Lancet Oncology Commission on Global Cancer Surgery builds on the first Commission by developing a pragmatic roadmap of practical solutions that we hope will ensure access to safe, timely, high-quality, and affordable cancer surgical care for everyone regardless of their socioeconomic status or geographic location.

BACKGROUND: It remains unclear if adherence to the planetary healthy diet (PHD), designed to improve human and environmental health, is associated with better cognitive function in aging, and if this association differs by apolipoprotein E (APOE) genotype. OBJECTIVES: We aimed to examine the association between the PHD pattern and risk of poor cognitive function, and to further assess whether the APOE ε4 allele could modify this association. METHODS: The study included 16,736 participants from the Singapore Chinese Health Study. The PHD score was calculated using data from a validated 165-item food frequency questionnaire at baseline (1993-1998), with higher scores indicating greater adherence to the PHD. Cognitive function was assessed by the Singapore-modified Mini-Mental State Examination at follow-up 3 visits (2014-2016). A subset of 9313 participants had APOE genotype data. Logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs), with adjustment for potential confounders. RESULTS: We identified 2397 (14.3%) cases of poor cognitive function. In the total population, OR (95% CI) of poor cognitive function for each one-SD increment in the PHD score was 0.89 (0.85, 0.93). Carriers of APOE ε4 allele had increased risk of poor cognitive function (OR: 1.36, 95% CI: 1.15, 1.61). There was a significant interaction between the PHD score and the APOE ε4 allele (P-interaction = 0.042). Each one-SD increment in the PHD score was significantly associated with lower risk of poor cognitive function (OR: 0.89; 95% CI: 0.83, 0.96) in non-carriers of APOE ε4 allele, but not in APOE ε4 allele carriers (OR: 1.04, 95% CI: 0.89, 1.23). CONCLUSIONS: Midlife adherence to the PHD was associated with reduced risk of poor cognitive function in later life. However, this was not observed in carriers of APOE ε4 allele who had higher risk of poor cognitive function.

BACKGROUND: The Planetary Health Diet Index (PHDI) measures adherence to the dietary pattern presented by the EAT-Lancet Commission, which aligns health and sustainability targets. There is a need to understand how PHDI scores correlate with dietary greenhouse gas emissions (GHGE) and how this differs from the carbon footprints of scores on established dietary recommendations. The objectives of this study were to compare how the PHDI, Healthy Eating Index-2015 (HEI-2015) and Dietary Approaches to Stop Hypertension (DASH) relate to (a) dietary GHGE and (b) to examine the influence of PHDI food components on dietary GHGE. METHODS: We used life cycle assessment data from the Database of Food Recall Impacts on the Environment for Nutrition and Dietary Studies to calculate the mean dietary GHGE of 8,128 adult participants in the 2015-2016 and 2017-2018 cycles of the National Health and Nutrition Examination Survey (NHANES). Poisson regression was used to estimate the association of (a) quintiles of diet score and (b) standardized dietary index Z-scores with dietary GHGE for PHDI, HEI-2015, and DASH scores. In secondary analyses, we used Poisson regression to assess the influence of individual PHDI component scores on dietary GHGE. RESULTS: We found that higher dietary quality on all three indices was correlated with lower dietary GHGE. The magnitude of the dietary quality-dietary GHGE relationship was larger for PHDI [-0.4, 95% CI (-0.5, -0.3) kg CO2 equivalents per one standard deviation change] and for DASH [-0.5, (-0.4, -0.6) kg CO2-equivalents] than for HEI-2015 [-0.2, (-0.2, -0.3) kg CO2-equivalents]. When examining PHDI component scores, we found that diet-related GHGE were driven largely by red and processed meat intake. CONCLUSIONS: Improved dietary quality has the potential to lower the emissions impacts of US diets. Future efforts to promote healthy, sustainable diets could apply the recommendations of the established DASH guidelines as well as the new guidance provided by the PHDI to increase their environmental benefits.

BACKGROUND: In 2019, a globally sustainable dietary pattern that primarily emphasizes the consumption of plant-based foods was proposed by the EAT-Lancet Commission. However, there is limited evidence regarding the association of this diet with coronary events. OBJECTIVES: To determine the association between the EAT-Lancet Reference Diet (ELD) and premature coronary artery disease (PCAD) risk and its severity. METHODS: This multi-center, case-control study was conducted within the framework of the Iran premature coronary artery disease (I-PAD). A total of 3185 participants aged under 70 years in women and 60 years in men were included. Cases were those whose coronary angiography showed stenosis ≥ 75% in at least one vessel or ≥ 50% in the left main artery (n = 2033), while the controls had normal angiography results (n = 1152). Dietary intake was assessed using a validated food frequency questionnaire. Logistic regression was utilized to examine the association between ELD and presence of PCAD. RESULTS: Compared with individuals in the first quartile, those in the highest quartile of ELD (OR = 0.29, 95% CI: 0.21, 0.39; P for trend < 0.001) and ELD calculated with minimum intake (OR = 0.39, 95% CI: 0.29, 0.52; P < 0.001) had lower risk of PCAD. Individuals in the highest quartile of adherence to the ELD and ELD with minimum intake had 78% and 72% lower risk of having severe PCAD compared with those in the lowest quartile, respectively. CONCLUSION: An inverse association was observed between adherence to the ELD and PCAD risk and its severity. Large-scale prospective cohort studies are required to confirm these findings.
RESUMO
PURPOSE: To describe adherence to sustainable healthy diets among a sample of 958 Chilean pre-schoolers (3-6 years) and explore associations between adherence and child and maternal sociodemographic and anthropometric characteristics. METHODS: Children's adherence to sustainable healthy diets was calculated from single multiple-pass 24-h dietary recalls using the Planetary Health Diet Index for children and adolescents (PHDI-C). Higher PHDI-C scores (max score = 150 points) represent greater adherence. Adjusted linear regression models were fitted to explore associations between PHDI-C scores and child and maternal characteristics. RESULTS: Children obtained low total PHDI-C scores (median 50.0 [IQR 39.5-59.8] points). This resulted from low consumption of nuts & peanuts, legumes, vegetables, whole cereals, and vegetable oils; a lack of balance between dark green and red & orange vegetables, inadequate consumption of tubers & potatoes and eggs & white meats, and excess consumption of dairy products, palm oil, red meats, and added sugars. Mean PHDI-C total score was significantly higher (50.6 [95%CI 49.6, 51.7] vs 47.3 [95%CI 45.0, 49.5]) among children whose mothers were ≥ 25 years compared to those with younger mothers. Positive associations were observed between scores for fruits and maternal education, vegetables and maternal age, added sugars and child weight status, while negative associations were observed between fruits and child age, and vegetable oils and maternal education. Scores for dairy products PHDI-C component were lower among girls. CONCLUSION: Adherence to sustainable healthy diets was low among this sample of Chilean children and was significantly associated with maternal age, being lower among children whose mothers were younger.
RESUMO
PURPOSE: To improve sustainability, adjustments to current diets are necessary. Therefore, limited planetary resources are considered within the healthy reference diet proposed by the EAT-Lancet Commission. The agreement with nationwide food intake was evaluated with two indices which reflect this reference and German food intake recommendations. METHODS: A healthy eating index (HEI-MON) reflecting the dietary guidelines of the German nutrition society and a planetary healthy eating index (PHEI-MON) reflecting the healthy reference diet were developed, with scores from 0 to 100. Both indices were applied to data from a nationally representative sample of the German population aged 18-79 years for which data from a 53-item food frequency questionnaire are available. RESULTS: Mean scores for the indices were 53 for HEI-MON and 39 for PHEI-MON. A better adherence to either guideline could be found among women, persons of older age as well as persons with higher education level. The sub-scores for HEI-MON showed high agreement with the recommendations for side dishes, fruit/nuts, (processed) meat and cereals, but low agreement with the recommendations for free sugar and vegetables/legumes. PHEI-MON sub-scores were highest for poultry, fruits and potatoes, and lowest for nuts, red meat and legumes. High scores in one index do not necessarily correspond to high scores in the other index. Individuals with more plantbased diets had higher scores in both indices, while high sugar and meat consumption led to lower scores. CONCLUSIONS: More plant-based diets are crucial for individual and planetary health. Both indices reflect such diets which consider already health and sustainability aspects. At an individual level, the scores for both indices may differ considerably, but overall there is a huge potential in the population to adapt to a diet more in line with both guidelines.
RESUMO
BACKGROUND: While healthy and sustainable diets benefit human and planetary health, their monetary cost has a direct impact on consumer food choices. This study aimed to identify the cost and environmental impact of the current Brazilian diet (CBD) and compare it with healthy and sustainable diets. METHODS: Data from the Brazilian Household Budget Survey 2017/18 and the Footprints of Foods and Culinary Preparations Consumed in Brazil database were used for a modeling study comparing the cost of healthy and sustainable diets (based on the Brazilian Dietary Guidelines (BDG) diet and the EAT-Lancet diet) versus the CBD. The DIETCOST program generated multiple food baskets for each scenario (Montecarlo simulations). Nutritional quality, cost, and environmental impact measures (carbon footprint (CF) and water footprint (WF)) were estimated for all diets and compared by ANOVA. Simple linear regressions used standardized environmental impacts measures to estimate differentials in costs and environmental impacts among diets scenarios. RESULTS: We observed significant differences in costs/1000 kcal. The BDG diet was cheaper (BRL$4.9 (95%IC:4.8;4.9) ≈ USD$1.5) than the CBD (BRL$5.6 (95%IC:5.6;5.7) ≈ USD$1.8) and the EAT-Lancet diet (BRL$6.1 (95%IC:6.0;6.1) ≈ USD$1.9). Ultra-processed foods (UPF) and red meat contributed the most to the CBD cost/1000 kcal, while fruits and vegetables made the lowest contribution to CBD. Red meat, sugary drinks, and UPF were the main contributors to the environmental impacts of the CBD. The environmental impact/1000 kcal of the CBD was nearly double (CF:3.1 kg(95%IC: 3.0;3.1); WF:2,705 L 95%IC:2,671;2,739)) the cost of the BDG diet (CF:1.4 kg (95%IC:1.4;1.4); WF:1,542 L (95%IC:1,524;1,561)) and EAT-Lancet diet (CF:1.1 kg (95%IC:1.0;1.1); WF:1,448 L (95%IC:1,428;1,469)). A one standard deviation increase in standardized CF corresponded to an increase of BRL$0.48 in the cost of the CBD, similar to standardized WF (BRL$0.56). A similar relationship between the environmental impact and the cost of the BDG (CF: BRL$0.20; WF: BRL$0.33) and EAT-Lancet (CF: BRL$0.04; WF: BRL$0.18) was found, but with a less pronounced effect. CONCLUSIONS: The BDG diet was cost-effective, while the EAT-Lancet diet was slightly pricier than the CBD. The CBD presented almost double the CF and WF compared to the BDG and EAT-Lancet diets. The lower cost in each diet was associated with lower environmental impact, particularly for the BDG and EAT-Lancet diets. Multisectoral public policies must be applied to guide individuals and societies towards healthier and more sustainable eating patterns.

BACKGROUND: Sustainable diets contribute to improving human health and reducing food-related greenhouse gas emissions (GHGE). Here, we established the effects of a facility-based sustainable diet intervention on the adherence to the EAT-Lancet Planetary Health Diet and GHGE of consumers. METHODS: In this quasi-experiment, vegan menus and educational material on sustainable diets were provided in the largest cafeteria of a German hospital for 3 months. Regular customers (> 1/week) in this cafeteria (intervention group) and in all other hospital cafeterias (control group) completed a questionnaire about their sociodemographic and dietary characteristics before and after the intervention period. We calculated difference-in-differences (DID), their 95% confidence intervals (CIs), and p-values for the adherence to the EAT-Lancet Planetary Health Diet Index (PHDI; 0-42 score points) and food-related GHGE. The protocol was registered at the German Clinical Trial Register (reference: DRKS00032620). FINDINGS: In this study population (N = 190; age range: 18-79 years; women: 67%; highest level of formal education: 63%), the mean baseline PHDI (25·1 ± 4·8 vs. 24·7 ± 5·8 points) and the mean baseline GHGE (3·3 ± 0·8 vs. 3·3 ± 0·7 kg CO2-eq./d) were similar between the intervention (n = 92) and the control group (n = 98). The PHDI increase was 0·6 points (95% CI: -0·4, + 1·6) higher in the intervention group than in the control group. This trend was stronger among frequent consumers of the vegan menu than among rare and never consumers. No between-group difference was seen for GHGE changes (DID: 0·0; 95% CI: -0·2, + 0·1 kg CO2-eq./d). INTERPRETATION: Pending verification in a longer-term project and a larger sample, this quasi-experiment in a big hospital in Germany suggests that offering vegan menus and information material in the cafeteria enhances the adherence to healthy and environmentally friendly diets among regular customers. These findings argue for making sustainable food choices the default option and for improving nutrition literacy.

AIM: We conducted a meta-analysis comparing the invasiveness of automatic lancet devices, which can collect adequate amount of blood at shallow puncture depths, with conventional manual lance devices (lancet or needle) to statistically identify less invasive instruments for neonatal heel lance. METHODS: We searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, and Ichushi databases for studies comparing the invasiveness between automatic lancet and manual lancet or needle in term and preterm neonates in neonatal intensive care unit. RESULTS: This review included 9 out of 449 searched articles, with 673 neonates. Automatic lancet had significantly lower pain scores (standardised mean difference: -2.0, 95% confidence interval: -3.3 to -0.7), heart rate (mean difference: -8.0, 95% confidence interval: -13.8 to -2.1), cry duration (mean difference: -21.5, 95% confidence interval: -32.5 to -10.4), number of punctures (mean difference: -0.6, 95% confidence interval: -1.1 to -0.2), and duration of procedures (mean difference: -37.7, 95% confidence interval: -75.2 to -0.2) than manual lancet or needle. Furthermore, peripheral oxygen saturation was significantly higher in automatic lancet than in manual lancet or needle (mean difference: 4.5, 95% confidence interval: 0.5-8.5). CONCLUSION: Automatic heel lancet devices were less invasive than manual heel lance devices (lancet or needle).

OBJECTIVES: The aim of this study was to explore the relationship between the EAT-Lancet diet (ELD) and head and neck cancers (HNCs) in 101,755 Americans enrolled in the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial. STUDY DESIGN: Prospective cohort study. METHODS: ELD score was calculated to assess participant's adherence to ELD. Cox hazard regression models were utilised to evaluate the association of ELD and dietary components with HNC risk. Restricted cubic spline (RCS) plots were employed to explore the linearity of the relationships. Predefined subgroup analyses and sensitivity analyses were performed to identify potential effect modifiers and to assess the stability of the findings, respectively. RESULTS: After a mean follow-up of 8.84 years, 279 cases of HNCs, including 169 cases of oral cavity and pharyngeal cancers and 110 cases of laryngeal cancer were recorded. This study observed a dose-response negative correlation between ELD and HNCs (hazard ratio [HR]Q4 vs Q1: 0.52; 95% confidence interval [CI]: 0.34, 0.80; P-trend = 0.003; HRper SD increment: 0.80; 95% CI: 0.71, 0.91), and oral cavity and pharyngeal cancers (HRQ4 vs Q1: 0.52; 95% CI: 0.31, 0.88; P-trend = 0.008; HRper SD increment: 0.78; 95% CI: 0.66, 0.92). Analysis using RCS plots indicated a significant linear association between adherence to the ELD and reduced risk of HNCs and oral cavity and pharyngeal cancers (P-nonlinearity > 0.05). Subgroup analysis did not reveal significant interaction factors (P-interaction > 0.05), and sensitivity analysis confirmed the robustness of this study. Additionally, negative correlations were found between the consumption of fruits and whole grains and HNCs (fruits: HRQ4 vs Q1: 0.58; 95% CI: 0.40, 0.84; P-trend = 0.010; whole grains: HRQ4 vs Q1: 0.51; 95% CI: 0.26, 0.97; P-trend = 0.004). CONCLUSION: Adherence to ELD contributes to the prevention of HNCs.

PURPOSE: The availability of children's surgical care in lower middle-income countries is lacking. The authors describe a hub and spoke global training initiative in children's surgery for adult teams from district hospitals (spokes) comprising general and orthopaedic surgeons, anaesthetists, and nurses and specialist children's surgical trainers from tertiary centres (hubs) in delivering the course. METHODS: The training course developed in Vellore, trained several sets of district hospital adult teams and trainer teams in India. Six specialist children's surgical trainer teams were invited from African countries to the course delivered in Vellore, India. The aim was to train them to deliver the course in their countries. RESULTS: Participants underwent a precourse 'train the trainer' program, observed and assessed the suitability of the district hospital training course. The program received positive feedback, government supported planning of similar courses in some of the countries and discussions in others. CONCLUSION: The availability of children's surgical care is similarly limited in the Asian and African continent, and the regions have shared challenges of disease burden, lack of access, poverty, deficient infrastructure, and trained human resources. They would benefit from this 'South to South' collaboration to impart training skills and modules to the children's surgical trainers.

Previous research has shown that adhering to the Eat-Lancet diet (ELD) is associated with a lower risk of chronic diseases and mortality. However, the associations between ELD and lung cancer incidence and mortality are unclear. To address this gap, we conducted a prospective cohort study involving 101,755 adults from the Prostate, Lung, Colorectal, and Ovarian (PLCO) trial in the USA. The ELD score was utilized to assess compliance with the ELD, with higher scores indicating greater compliance. We employed Cox regression analyses to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of ELD score with the incidence and mortality of lung cancer and its subtypes. In addition, sensitivity analyses were performed to ensure the robustness of our findings. In total, 1706 cases of lung cancer and 1217 lung cancer-associated deaths were recorded during the study period. Our analysis revealed that higher ELD scores were significantly associated with a reduced incidence (HRQuartile 4 vs. Quartile 1 : 0.73; 95% CI: 0.60, 0.89; ptrend = 0.001) and mortality (HRQuartile 4 vs. Quartile 1 : 0.74; 95% CI: 0.59, 0.93; ptrend = 0.005) of lung cancer in a dose-response manner (all pnonlinearity > 0.05). The reliability of these results was supported by sensitivity analyses. Notably, these associations were primarily observed in non-small-cell lung cancer. In conclusion, our findings suggest that adherence to the ELD may be associated with a reduced risk of lung cancer incidence and mortality.

BACKGROUND: The EAT-Lancet Commission proposed a global reference diet with both human health benefits and environmental sustainability in 2019. However, evidence regarding the association of such a diet with the risk of atrial fibrillation (AF) is lacking. In addition, whether the genetic risk of AF can modify the effect of diet on AF remains unclear. This study aimed to assess the association of the EAT-Lancet diet with the risk of incident AF and examine the interaction between the EAT-Lancet diet and genetic susceptibility of AF. METHODS: This prospective study included 24,713 Swedish adults who were free of AF, coronary events, and stroke at baseline. Dietary habits were estimated with a modified diet history method, and an EAT-Lancet diet index was constructed to measure the EAT-Lancet reference diet. A weighted genetic risk score was constructed using 134 variants associated with AF. Cox proportional hazards regression models were applied to estimate the hazard ratio (HR) and 95% confidence interval (CI). RESULTS: During a median follow-up of 22.9 years, 4617 (18.7%) participants were diagnosed with AF. The multivariable HR (95% CI) of AF for the highest versus the lowest group for the EAT-Lancet diet index was 0.84 (0.73, 0.98) (P for trend < 0.01). The HR (95% CI) of AF per one SD increment of the EAT-Lancet diet index for high genetic risk was 0.92 (0.87, 0.98) (P for interaction = 0.15). CONCLUSIONS: Greater adherence to the EAT-Lancet diet index was significantly associated with a lower risk of incident AF. Such association tended to be stronger in participants with higher genetic risk, though gene-diet interaction was not significant.

BACKGROUND: Tools for measuring adherence to sustainable healthy diets among children and adolescents are lacking. OBJECTIVE: To advance methods for measuring adherence to sustainable healthy diets among children and adolescents by adapting an existing index, compare scores obtained using the original and adapted versions of the index in a sample of Chilean children, and describe the adapted index association with diet characteristics. METHODS: The Planetary Health Diet Index (PHDI) was adapted to better reflect children's and adolescents' nutritional requirements. The adapted index (PHDI-C) comprises 16 components with a maximum score of 150 points. PHDI-C was piloted among a sample of 958 Chilean children (3-6 years) using dietary data collected in 2016 through single 24-h recalls. A decision tree and food disaggregation methodology were developed to guide the calculation of scores. Scores obtained using the original and adapted versions of the index were compared. Linear regression models adjusted by child's gender and age were fitted to explore associations between total PHDI-C score, dietary recall characteristics and nutritional composition of children's diets. RESULTS: PHDI accounted for 75.7% of children's total caloric intake, whereas PHDI-C accounted for 99.6%. PHDI & PHCI-C scores were low among this sample of children; however, mean total score was lower when using PHDI compared to PHDI-C [40.7(12.1) vs 50.1(14.6)]. Children's scores were very low for nuts & peanuts, legumes, dark green vegetables, whole cereals, tubers & potatoes, and added sugars components across both indices, but were higher for dairy products and eggs & white meats components when using the PHDI-C due to adjustments made to ensure nutritional adequacy. Mean total PHDI-C score was significantly lower on weekends and special occasions, and significantly higher when children reported having a special diet (e.g., vegetarian). Total PHDI-C score was negatively associated with total sugars, saturated fats, trans fats, and animal-based protein intake, and positively associated with total protein, plant-based protein, total carbohydrates, and total fibre intake. CONCLUSIONS: This study provides a replicable method for measuring adherence to sustainable healthy diets among children and adolescents that can be used to monitor trends and measure the effectiveness of actions targeting improving children's diets.

PURPOSE: Type 2 diabetes is a global health problem. While a healthy diet lowers risk of type 2 diabetes, less is known about diets with low climate impact. This study aimed to investigate adherence to the EAT-Lancet diet and risk of type 2 diabetes in a Danish setting. METHODS: In the Danish Diet, Cancer and Health cohort, dietary data were collected using a validated 192-item food frequency questionnaire, at recruitment in 1993-1997. In total, 54,232 participants aged 50-64 years at baseline with no previous cancer or diabetes diagnoses were included in the current analyses. The EAT-Lancet diet score was used to assess adherence to the EAT-Lancet diet. Participants scored 0 (non-adherence) or 1 (adherence) point for each of the 14 dietary components of the diet score (range 0-14 points). Participants were followed through register linkage until type 2 diabetes diagnosis or censoring. Hazard ratios and 95% confidence intervals (CI) were estimated using multivariable-adjusted Cox regression models. RESULTS: During a median 15-year follow-up period, 7130 participants developed type 2 diabetes. The hazard ratio for developing type 2 diabetes was 0.78 (95% CI 0.71; 0.86) for those with highest EAT-Lancet diet scores (11-14 points) compared to those with lowest scores (0-7 points) after adjusting for potential confounders. After further adjusting for potential mediators, including BMI, the corresponding hazard ratio was 0.83 (95% CI 0.76; 0.92). CONCLUSION: Greater adherence to the EAT-Lancet diet was associated with a lower risk of developing type 2 diabetes in a middle-aged Danish population.

PURPOSE: The EAT-Lancet Commission released a reference sustainable diet to improve human health and respect the planetary boundaries. The Planetary Health Diet Index (PHDI) was developed with the purpose of evaluate the adherence to this reference diet. The aim of the present study was to evaluate the association between adherence to the EAT-Lancet diet with cardiometabolic risk profile. METHODS: We used the cross-sectional baseline data from 14,155 participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a multicenter ongoing cohort study. Dietary data were collected using a 114-item validated food frequency questionnaire. The PHDI was used to assess the adherence to the EAT-Lancet diet. It consists of 16 components and the total score can range from 0 to 150 points. Linear, logistic and quasi-Poisson regression models were built to evaluate the associations between PHDI and the outcomes. RESULTS: Individuals with higher adherence to EAT-Lancet diet (PHDI, 5th quintile) had lower values for systolic blood pressure (ß - 0.84; 95% CI - 1.66: - 0.01), diastolic blood pressure (ß - 0.70; 95% CI - 1.24: - 0.15), total cholesterol (ß - 3.15; 95% CI - 5.30: - 1.01), LDL-c (ß - 4.10; 95% CI - 5.97: - 2.23), and non-HDL-cholesterol (ß - 2.57; 95% CI - 4.62: - 0.52). No association was observed for HDL-c, triglycerides and HOMA-IR. CONCLUSIONS: Our results indicate that higher adherence to the EAT-Lancet diet is associated with lower levels of blood pressure, total cholesterol, LDL-c, and non-HDL-c.

PURPOSE: The EAT-Lancet Commission proposed an evidence-based global reference diet to improve human health within planetary boundaries. Recently, the Planetary Health Diet Index (PHDI) was developed based on the EAT-Lancet recommendations and validated among Brazilian adults. However, the relative validity of the PHDI in adolescents has yet to be assessed. Thus, we aimed to evaluate the relative validity of the PHDI in European adolescents. METHODS: We used cross-sectional data from 1804 adolescents (12.5-17.5 years) enrolled in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study. The PHDI (0-150 points) was calculated based on dietary intake data from two non-consecutive 24-h dietary recalls. Associations between the PHDI and usual nutrient intakes, plasma food consumption biomarkers, and adherence to the Mediterranean diet were evaluated using multivariable-adjusted mixed-effects linear regression models. RESULTS: Higher PHDI score was associated with greater intakes of nutrients predominantly from plant-source foods, such as vegetable protein, vitamin E, and folate and with lower intake of nutrients predominately from animal-source foods, such as total and saturated fat, cholesterol, and animal protein. Furthermore, a higher PHDI score was also positively associated with plasma ß-carotene, vitamin C, vitamin D, folate, and ferritin concentrations, while negatively associated with trans-fatty acids concentration. Moreover, higher PHDI was related to a greater adherence to the Mediterranean dietary pattern. CONCLUSIONS: The PHDI showed good relative validity among adolescents in the HELENA study. Hence, future research should assess adherence to the PHDI and long-term health outcomes.

OBJECTIVE: Asthma imposes a significant health and socioeconomic burden with an average prevalence impacting 5-10% of the global population. The aim of this narrative review is to update the current literature on topics related to asthma diagnosis. DATA SOURCES: Original research articles were identified from PubMed using the search terms "asthma diagnosis" and "asthma misdiagnosis". STUDY SELECTIONS: Recently published articles (n = 51) detailing the diagnosis, misdiagnosis of asthma, and the updated recommendations of the European and international asthma guidelines. RESULTS: Emerging evidence revealed that asthma might represent a rather heterogenous clinical entity with varying underlying molecular mechanisms. Attempts have been made to unravel these traits to better provide accurate diagnosis and a more efficient patient-based management approach. The lack of a gold standard test for asthma diagnosis has contributed to its over- and underdiagnosis. This is problematic, given that overdiagnosis might lead to delay of both diagnosis and prompt treatment of other diseases, while underdiagnosis might substantially impact quality of life due to progression of asthma by increased rate of exacerbations and airway remodeling. In addition to poor asthma control and potential patient harm, asthma misdiagnosis is also associated with excessive costs. As a result, current international guidelines emphasize the need for a standardized approach to diagnosis, including objective measurements prior to treatment. CONCLUSION: Future research is warranted to define the optimal diagnostic and treatable traits approach especially for patients with severe asthma, as they may benefit from the advent of newly targeted asthma management.

Progress on surgical system strengthening has been slow due to a disconnect between evidence generation and the information required for effective policymaking. This systematic mapping review sought to assess critical research gaps in the field of global surgery guided by the World Health Organisation Health Systems building block framework, analysis of authorship and funding patterns, and an exploration of emerging research partnership networks. Literature was systematically mapped to identify, screen, and synthesize results of publications in the global surgery field between 2015 and March 2022. We searched four databases and included literature published in seven languages. A social network analysis determined the network attributes of research institutions and their transient relationships in shaping the global surgery research agenda. We identified 2,298 relevant studies out of 92,720 unique articles searched. Research output increased from 453 in 2015-16 to 552 in 2021-22, largely due to literature on Covid-19 impacts on surgery. Sub-Saharan Africa (792/2298) and South Asia (331/2298) were the most studied regions, although high-income countries represented a disproportionate number of first (42%) and last (43%) authors. Service delivery received the most attention, including the surgical burden and quality and safety of services, followed by capacity-building efforts in low- and middle-income countries. Critical research in economics and financing, essential infrastructure and supplies, and surgical leadership necessary to guide policy decisions at the country level were lacking. Global surgical systems remain largely under-researched. Knowledge diffusion requires an emphasis on developing sustainable research partnerships and capacity across low- and middle-income countries. A renewed focus must be given to equipping countries with tools for effective decision-making to enhance investments in high-quality surgical services.

BACKGROUND: Environmentally sustainable diets are represented in the EAT-Lancet recommendations developed by the Lancet Commission on Planetary Health in 2019. Very few studies have compared Indian diets with the EAT-Lancet recommendations. The present study performed such a comparison using primary dietary consumption data from adults in north and south India. METHODS: Data from 8762 adults (52.4 ± 11.7 years) residing in Sonipat and Vizag India were collected on sociodemographic characteristics, wealth index (household assets) and dietary intake (food frequency questionnaire: nine food groups). The quantity consumed and energy from each food group was compared with the EAT-Lancet recommendations. We investigated the likelihood of deficit or excess in consumption compared to the EAT-Lancet recommendations by different sociodemographic factors. RESULTS: Half of the participants were women and half resided in rural areas. Vegetables and fruits were consumed in lower quantity, whereas dairy and added fats were consumed in higher quantity than recommended by the EAT-Lancet recommendations. For whole grains, female gender and poorest wealth index were the factors associated with deficit or no consumption, whereas, for vegetables and fruits, it was poorest wealth index and residence in rural areas (p < 0.05, all). Rural residence and poorest wealth index were associated with excess consumption of dairy and added fats (p < 0.05, all). CONCLUSIONS: The diets of the study participants were mainly plant-based, and high in dairy but lacking in nutrient-rich foods such as vegetables and fruits. Appropriate policy actions for making healthy sustainable diets and micronutrient-rich foods available and affordable to all with a particular focus on the poor and rural populations are warranted.
