    In Peru, the high Andean regions made up of grasslands are important for the sustainability of local systems. Improving and promoting the sustainability of forage production and quality allows producers to be resilient in the face of constant environmental changes. In this study, the morphological characteristics (plant height, leaf length and width), yield (fresh and dry matter) and nutritional characteristics [ash, ether extract, crude protein (CP), crude fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), in vitro digestibility of dry matter (IVDMD), nitrogen-free extract (NFE) and gross energy] of Cichorium intybus L. and Plantago lanceolata L. were evaluated, according to the cutting interval. Six experimental plots were implemented, three per species in each of C. intybus and P. lanceolata . An analysis of variances under a linear mixed model was performed of morphological and yield characteristics, including the cutting interval (28, 35 and 42 days), and the harvest (1, 2, 3 and 4 harvests) as fixed effects, while the plants were considered as a random effect. Tukey’s multiple comparisons test (p < 0.05) was used to group the results by species using R software. The number of leaves in C. intybus and P. lanceolata were higher at a cutting interval of 42 days of age and in the third and fourth harvest (p<0.05). The dry matter yield of C. intybus and P. lanceolata at 42 days was higher than that of the 28 and 35 days cut, with values of 1645 kg/ha and 1545 kg/ha, respectability. The nutritional parameters of C. intybus and P. lanceolata varied significantly according to harvest age (p<0.05). Ash, CP, NDF and ADF decreased, while IVDMD and NFE increased according to age. The CP concentration was 20.84% at 28 days, 18.99% at 35 days and 17.82% at 42 days in C. intybus and 19.29% at 28 days, 17.80% at 35 days and 15.17% at 42 days, while the IVDMD increased from 88.5% to 94.00% in C. intybus and 77.82% to 88.65% in P. lanceolata . Harvest age is key to optimizing yield and quality of C. intybus and P. lanceolata in high Andean livestock systems.

    Background: Emotional eating, defined as the tendency to eat in response to emotions, has been associated with various biopsychosocial factors. However, in the Peruvian context, there is limited evidence regarding the specific predictors of this eating behavior in adolescents. Objective: To examine the associations between saturated fat intake, sleep duration, body mass index (BMI), depressive symptoms, age and sex, and emotional eating in Peruvian adolescents. Methods: This was a predictive cross-sectional study based on non-probabilistic sampling. A total of 722 adolescents from four schools located in East Lima were included. A multiple linear regression model was employed to examine the relationships between age, sex, saturated fat intake (SFI), sleep duration, BMI, and depressive symptoms and emotional eating. Results: The model was statistically significant (adjusted R2 = 0.301; F = 45.276; p < 0.001), explaining 30.1% of the variance in emotional eating based on the explanatory variables. Being female (β = 0.208; p = 0.011), aged 15 to 18 versus 12 to 14 years (β = 0.083; p < 0.001), having a high SFI (β = 0.186; p < 0.001), sleeping ≥ 7 h (β = −0.126; p < 0.001), and a higher BMI (β = −0.082; p = 0.011) were significantly associated with emotional eating. Depressive symptoms (β = 0.365; p < 0.001) emerged as the strongest predictor in the model. Conclusions: Emotional eating among Peruvian adolescents is associated with psychological, behavioral, and sociodemographic factors. Depressive symptoms showed the strongest association, while longer sleep duration was linked to lower emotional eating scores. These findings highlight the need for integrated interventions targeting mental health, sleep hygiene, and healthy dietary behaviors in adolescents.

    Importance: The use of hypertonic saline (HTS) vs mannitol in the control of elevated intracranial pressure (ICP) secondary to neurotrauma is debated. Objective: To compare mortality and functional outcomes of treatment with 3% HTS vs 20% mannitol among children with moderate to severe traumatic brain injury (TBI) at risk of elevated ICP. Design, Setting, and Participants: This prospective, multicenter cohort study was conducted between June 1, 2018, and December 31, 2022, at 28 participating pediatric intensive care units in the Pediatric Acute and Critical Care Medicine in Asia Network (PACCMAN) and the Red Colaborativa Pediátrica de Latinoamérica (LARed) in Asia, Latin America, and Europe. The study included children (aged <18 years) with moderate to severe TBI (Glasgow Coma Scale [GCS] score ≤13). Exposure: Treatment with 3% HTS compared with 20% mannitol. Main Outcomes and Measures: Multiple log-binomial regression analysis was performed for mortality, and multiple linear regression analysis was performed for discharge Pediatric Cerebral Performance Category (PCPC) scores and 3-month Glasgow Outcome Scale-Extended Pediatric Version (GOS-E-Peds) scores. Inverse probability of treatment weighting was also performed using the propensity score method to control for baseline imbalance between groups. Results: This study included 445 children with a median age of 5.0 (IQR, 2.0-11.0) years. More than half of the patients (279 [62.7%]) were boys, and 344 (77.3%) had severe TBI. Overall, 184 children (41.3%) received 3% HTS, 82 (18.4%) received 20% mannitol, 69 (15.5%) received both agents, and 110 (24.7%) received neither agent. The mortality rate was 7.1% (13 of 184 patients) in the HTS group and 11.0% (9 of 82 patients) in the mannitol group (P = .34). After adjusting for age, sex, presence of child abuse, time between injury and hospital arrival, lowest GCS score in the first 24 hours, and presence of extradural hemorrhage, no between-group differences in mortality, hospital discharge PCPC scores, or 3-month GOS-E-Peds scores were observed. Conclusions and Relevance: In this cohort study of children with moderate to severe TBI, the use of HTS was not associated with increased survival or improved functional outcomes compared with mannitol. Future large multicenter randomized clinical trials are required to validate these findings.

    = 1,183). Data were collected during the year 2020, between April 01 and June 30 in Spain and between July 13 and September 26, in the other countries studied using a self-administered online survey designed for the assessment of sociodemographic, employment, physical activity, health status, and dietary habits changes. Most participants (61.6%), mainly those from Spain, remained constant, without improving or worsening their pattern of food consumption. Among those who changed, a pattern of better eating choices prevailed (22.7%) in comparison with those who changed toward less healthy choices (15.7%). Argentina and Brazil showed the highest proportion of changes toward a healthier pattern of food consumption. Peruvians and Mexicans were less likely to make healthy changes in food consumption (OR: 0.51; 95% CI: 0.4-0.6 and OR: 0.69; 95% CI: 0.4-0.8, respectively), when compared to Argentinians. Most respondents did not change their pattern of meal consumption, but those who did reduced their consumption of main meals and increased intake of small meals and snacks. Although most participants affirmed to be doing physical activity at home, about one-half reported perception of weight gain. Individuals with alterations in sleep pattern (either by increasing or decreasing sleep time) were more likely to change their diets to a healthier pattern. In contrast, individuals with confirmed diagnosis of COVID-19 and those who reported feeling anxious were more likely to perform changes to a less healthy eating pattern (OR: 1.72; 95% CI: 1.2-2.3 and OR: 1.21; 95% CI: 1.1-1.4, respectively). In conclusion, although most participants remained constant in their eating habits, lifestyle changes and anxiety feelings were reported. Among those who changed patterns of food consumption, healthier choices prevailed, with differences between countries. However, there were alterations in the distribution of meals, with higher consumption of snacks and small meals. These results can be used to guide policies to prevent deleterious consequences that may affect the incidence of chronic diseases.

    Lung cancer (LC) is a leading cause of mortality, claiming more than 1.8 million deaths per year worldwide. Surgery is one of the most effective treatments when the disease is in its early stages. The study of metabolic alterations after surgical intervention with curative intent could be used to assess the response to treatment or the detection of cancer recurrence. In this study, we have evaluated the metabolomic profile of serum samples (n = 110) from preoperative (PRE) and postoperative (POST) LC patients collected at two different time points (1 month, A; 3–6 months, B) with respect to healthy people. An untargeted metabolomic platform based on reversed phase (RP) and hydrophilic interaction chromatography (HILIC), using ultra-high performance liquid chromatography (UHPLC) and mass spectrometry (MS), was applied (MassIVE ID MSV000092213). Twenty-two altered metabolites were annotated by comparing all the different studied groups. DG(14,0/22:1), stearamide, proline, and E,e-carotene-3,3′-dione were found altered in PRE, and their levels returned to those of a baseline control group 3–6 months after surgery. Furthermore, 3-galactosyllactose levels remained altered after intervention in some patients. This study provides unique insights into the metabolic profiles of LC patients after surgery at two different time points by combining complementary analytical methods.

    BACKGROUND: Peru has one of the highest infection and death rates in the world for the COVID-19 pandemic. The government implemented house confinement measures with probable consequences on lifestyle, particularly affecting eating habits, physical activity, sleep quality, and mental health. OBJECTIVES: The aim of this study was to assess the lifestyles, physical activity, and sleep characteristics, as well as changes in eating habits in a Peruvian population during the first wave of the COVID-19 pandemic. METHODS: A cross-sectional descriptive study was performed. We analyzed Peruvian adults based on an online self-administered questionnaire divided into sociodemographic, anthropometrics, COVID-19 diagnosis reported, lifestyle habits, and frequency of consumption of foods. RESULTS: During confinement for COVID-19, 1176 participants were studied. Of these, most reported weight gain (1 to 3 kg) and 35.7% were overweight. The lifestyles habits showed that 54.8% reported doing physical activity and 37.2% sleep less. The Peruvian sample presented a main meal pattern of breakfast (95.7%), lunch (97.5%), and dinner (89.1%). Likewise, eating habits before and during COVID-19 pandemic showed that vegetables (OR:1.56, CI95% 1.21-200), fruit (OR: 1.42, CI95% 1.10-1.81), legumes (OR:1.67, CI95% 1.23-2.28), and eggs (OR: 2.00, CI95% 1.52-2.65) presented significant consumption increase during social isolation, while bakery products (OR: 0.74, CI95% 0.56-0.97), meat, snack, refreshment, and fast food decreased in consumption. Other foods showed no significant differences. CONCLUSION: This study showed an important frequency of overweight and sleep changes. There was a slight increase in physical activity despite the social isolation measures and an increase in healthy eating habits; nevertheless, the majority reported gaining weight.

    In order to prioritize public policies to reduce the consumption of sugar-sweetened beverages in Argentina, Brazil, El Salvador and Trinidad and Tobago and to identify information gaps related to the burden of disease attributable to their consumption, a policy dialogue was held with government members, civil society organizations, researchers and communicators from Latin American and Caribbean countries. Presentations and deliberative workshops were conducted using semi-structured data collection tools and group discussions. The prioritized interventions were tax increases, front labeling, restriction of advertising, promotion and sponsorship, and modifications regarding the school environment. The main perceived barrier was the interference from the food industry. This dialogue among decision-makers led to the identification of priority public policies to reduce the consumption of sugar-sweetened beverages in the region.

    Background: Cervical cytology remains widely used as the initial tool in cervical cancer screening worldwide. WHO guidelines recommend replacing cytology with primary HPV testing to reach cervical cancer elimination goals. We assessed the performance of cytology and high-risk HPV testing to detect cervical precancer, cervical intraepithelial neoplasia (CIN) grade 3 or worse (CIN3+) among women aged 30-64 years participating in the ESTAMPA study. Methods: Women were screened with cytology and HPV across ESTAMPA study centres in Latin America. Screen-positives were referred to colposcopy with biopsy collection and treatment as needed. Those with no evident precancer were recalled at 18-months for a second HPV test to complete disease ascertainment. Performance indicators for cytology and HPV to detect CIN3+ were estimated. Findings: 30,606 participants with available cytology and HPV results were included in the analysis. A total of 440 histologically confirmed CIN3s and 30 cancers were diagnosed. Cytology sensitivity for CIN3+ was 48.5% (95% CI: 44.0-53.0), whereas HPV testing had a sensitivity of 98.1% (95% CI: 96.3-96.7). Specificity was 96.5% (95% CI: 96.3-96.7) using cytology and 88.7% (95% CI: 88.3-89.0) with HPV. Performance estimates varied substantially by study centre for cytology (ranging from 32.1% to 87.5% for sensitivity and from 89.2% to 99.5% for specificity) while for HPV results were more consistent across sites (96.7%-100% and 83.6-90.8%, respectively). Interpretation: The limited and highly variable sensitivity of cytology strongly supports transition to the more robust and reproducible HPV-based cervical screening to ensure progress towards global cervical cancer elimination targets in Latin America. Funding: IARC/WHO, UNDP, HRP/WHO, NCI and local funders.

    The objective of this study was to correlate the educational achievement (EA) of Chilean elementary and high-school graduates with their food habits. For this purpose, a random sample of 550 schoolers from the Metropolitan Area of Santiago, Chile, graduating from elementary and high school (1:1) of both sexes (1:1), from public and private schools and from high, medium and low socioeconomic status (SES) (1:1:1), was selected. Food habits were determined through a specially designed questionnaire and defined as the frequency of consumption of the food groups, expressed as days per week. The EA was established through the Achievement Evaluation Program (AEP) and Academic Aptitude Test (AAT) in elementary-and high-school graduates-, respectively. Results revealed that EA was found significantly and positively correlated with the frequency of consumption of dairy products, meat products and eggs, in both elementary and high school graduates. A significant and inverse correlation between EA and the frequency of vegetables and fruits consumption was observed in both educational levels, and with miscellaneous products, only in elementary school graduates. Food habits explained 24.4% and 16.6% of the EA variance, in elementary and high school graduates, respectively. The frequency of consumption of dairy products was the independent variable with the greatest explanatory power in EA variance (approximately above 70% of the explained variance). These results are important to consider for educational planning focused on the School Feeding Program.
