Growth faltering in children (low length for age or low weight for length) during the first 1,000 days of life (from conception to 2 years of age) influences short-term and long-term health and survival1,2. Interventions such as nutritional supplementation during pregnancy and the postnatal period could help prevent growth faltering, but programmatic action has been insufficient to eliminate the high burden of stunting and wasting in low- and middle-income countries. Identification of age windows and population subgroups on which to focus will benefit future preventive efforts. Here we use a population intervention effects analysis of 33 longitudinal cohorts (83,671 children, 662,763 measurements) and 30 separate exposures to show that improving maternal anthropometry and child condition at birth accounted for population increases in length-for-age z-scores of up to 0.40 and weight-for-length z-scores of up to 0.15 by 24 months of age. Boys had consistently higher risk of all forms of growth faltering than girls. Early postnatal growth faltering predisposed children to subsequent and persistent growth faltering. Children with multiple growth deficits exhibited higher mortality rates from birth to 2 years of age than children without growth deficits (hazard ratios 1.9 to 8.7). The importance of prenatal causes and severe consequences for children who experienced early growth faltering support a focus on pre-conception and pregnancy as a key opportunity for new preventive interventions.

Sustainable Development Goal 2.2-to end malnutrition by 2030-includes the elimination of child wasting, defined as a weight-for-length z-score that is more than two standard deviations below the median of the World Health Organization standards for child growth1. Prevailing methods to measure wasting rely on cross-sectional surveys that cannot measure onset, recovery and persistence-key features that inform preventive interventions and estimates of disease burden. Here we analyse 21 longitudinal cohorts and show that wasting is a highly dynamic process of onset and recovery, with incidence peaking between birth and 3 months. Many more children experience an episode of wasting at some point during their first 24 months than prevalent cases at a single point in time suggest. For example, at the age of 24 months, 5.6% of children were wasted, but by the same age (24 months), 29.2% of children had experienced at least one wasting episode and 10.0% had experienced two or more episodes. Children who were wasted before the age of 6 months had a faster recovery and shorter episodes than did children who were wasted at older ages; however, early wasting increased the risk of later growth faltering, including concurrent wasting and stunting (low length-for-age z-score), and thus increased the risk of mortality. In diverse populations with high seasonal rainfall, the population average weight-for-length z-score varied substantially (more than 0.5 z in some cohorts), with the lowest mean z-scores occurring during the rainiest months; this indicates that seasonally targeted interventions could be considered. Our results show the importance of establishing interventions to prevent wasting from birth to the age of 6 months, probably through improved maternal nutrition, to complement current programmes that focus on children aged 6-59 months.

Globally, 149 million children under 5 years of age are estimated to be stunted (length more than 2 standard deviations below international growth standards)1,2. Stunting, a form of linear growth faltering, increases the risk of illness, impaired cognitive development and mortality. Global stunting estimates rely on cross-sectional surveys, which cannot provide direct information about the timing of onset or persistence of growth faltering-a key consideration for defining critical windows to deliver preventive interventions. Here we completed a pooled analysis of longitudinal studies in low- and middle-income countries (n = 32 cohorts, 52,640 children, ages 0-24 months), allowing us to identify the typical age of onset of linear growth faltering and to investigate recurrent faltering in early life. The highest incidence of stunting onset occurred from birth to the age of 3 months, with substantially higher stunting at birth in South Asia. From 0 to 15 months, stunting reversal was rare; children who reversed their stunting status frequently relapsed, and relapse rates were substantially higher among children born stunted. Early onset and low reversal rates suggest that improving children's linear growth will require life course interventions for women of childbearing age and a greater emphasis on interventions for children under 6 months of age.

Several recently developed methods have the potential to harness machine learning in the pursuit of target quantities inspired by causal inference, including inverse weighting, doubly robust estimating equations and substitution estimators like targeted maximum likelihood estimation. There are even more recent augmentations of these procedures that can increase robustness, by adding a layer of cross-validation (cross-validated targeted maximum likelihood estimation and double machine learning, as applied to substitution and estimating equation approaches, respectively). While these methods have been evaluated individually on simulated and experimental data sets, a comprehensive analysis of their performance across real data based simulations have yet to be conducted. In this work, we benchmark multiple widely used methods for estimation of the average treatment effect using ten different nutrition intervention studies data. A nonparametric regression method, undersmoothed highly adaptive lasso, is used to generate the simulated distribution which preserves important features from the observed data and reproduces a set of true target parameters. For each simulated data, we apply the methods above to estimate the average treatment effects as well as their standard errors and resulting confidence intervals. Based on the analytic results, a general recommendation is put forth for use of the cross-validated variants of both substitution and estimating equation estimators. We conclude that the additional layer of cross-validation helps in avoiding unintentional over-fitting of nuisance parameter functionals and leads to more robust inferences.

Recreational facilities are widely regarded as one of the largest sources of and contributors to the tourism of countries worldwide. Given this, this study aimed to examine adults’ general behavioral intentions and actual visitation to amusement and recreational facilities. A total of 1367 adult and young-adult Filipinos voluntarily answered a self-administered survey consisting of measure items drawing on the extended theory of planned behavior framework. Structural equation modeling was employed for the simultaneous analysis of all latent variables and their causal relationships, and the marketing mix greatly affected the hedonic motivation and perceived behavioral control, leading to an indirect effect on behavioral intentions and actual visitation. Subjective norms and attitudes also had a significant direct effect on behavioral intentions and indirect effects on actual visitation. Interestingly, the marketing mix prompted a higher significant effect than behavioral intentions on actual visitation. It was implied that consumers are going to recreational facilities and amusement parks when they can visit an area, access a location, participate in different activities, and have enough resources. Businesses may capitalize on this finding in promoting their amusement parks and recreational facilities. In addition, they may highlight their location and space because they are among the highly significant measured items that the participants noted. The results of this study provides insights into the strategies, individual behavior, and motivation aspects. Implications and managerial insights are provided for the study’s adoption and extension worldwide.

Introducción. En becerras prepúberes la Kisspeptina-10 ha estimulado la secreción de la hormona luteinizante (LH) y folículo estimulante (FSH), y en vacas posparto amamantando ha estimulado la secreción de LH sin evidencia de inducir la ovulación. Objetivo. Inducir la ovulación con Kisspeptina-10 u hormona liberadora de gonadotropinas (GnRH) en vacas productoras de carne en condiciones subtropicales de México. Materiales y métodos. El estudio se realizó en la región nororiente del estado de Puebla, del 2020 al 2021, con 252 vacas cruzadas Bos taurus x Bos indicus. El protocolo de sincronización estral consistió en la aplicación de un dispositivo intravaginal impregnado con progesterona (1,9 g) y la inyección intramuscular de 2 mg de benzoato de estradiol (día 0). El día siete se removió el dispositivo intravaginal y de inmediato las vacas fueron inyectadas vía intramuscular con 0,150 mg de D-cloprostenol. Al día siguiente (día ocho), las vacas fueron inyectadas vía intramuscular con 1 mg de benzoato de estradiol. Entre 52 y 56 horas posteriores al retiro del dispositivo intravaginal (día nueve), las vacas se inyectaron vía intramuscular con GnRH o Kisspeptina-10. Las vacas se asignaron a cuatro tratamientos: T1, 100 µg de GnRH (control positivo), T2, T3 y T4 500 µg, 1000 µg y 1500 µg de Kisspeptina-10, respectivamente. La ovulación se detectó mediante ultrasonografía a los cuatro días post-tratamiento. La variable de respuesta evaluada fue la tasa de ovulación. Los datos se analizaron mediante modelos lineales generalizados y se aplicó una función liga logit. Resultados. Las tasas de ovulación obtenidas con T1 y T4 fueron iguales estadísticamente (99,9 %; p>0,05) y mayores (p0,05). Conclusión. La Kisspeptina-10 fue tan efectiva como la GnRH para inducir la ovulación.

The aim of this work was to evaluate the effect of different cutting lengths, the use of biostimulants and diameter of cuttings on hops vegetative propagation. The work was conducted in a greenhouse at the Center for Agricultural Sciences (CCA) at the Federal University of Santa Catarina (UFSC), in Florianópolis/SC, Brazil, between October 2019 and January 2021. In experiment 1, cuttings with one, two and three buds were tested, with and without application of biostimulant SprintAlga TS® (Biolchim) in Brewer's Gold and Cascade cultivars. In experiment 2, cuttings with diameter of 1.5 cm, 2.5 cm and 3.5 cm were tested for Northern Brewer cultivar. In both experiments, survival, rooting, root length, root quality, number of shoots and shoot length were evaluated. In experiment 1, Cascade had lower survival, rooting and development compared to Brewer's Gold. The use of biostimulant increased survival and rooting rates of both cultivars. For Brewer's Gold the use of biostimulant improved root quality and increased shoot number, root and shoot length. For Brewer's Gold, 3-bud cuttings improved root quality and increased number of shoots. For Cascade, 1-bud cuttings showed the highest survival, rooting and development rates. In experiment 2, the highest rates of survival, rooting and the longest root length were obtained with 1.5 cm diameter cuttings. Larger diameter cuttings (2.5 and 3.5 cm) produced fewer shoots, but longer shoots.

The C-X-C motif chemokine ligand 17 (CXCL17) is chemotactic for myeloid cells, exhibits bactericidal activity, and exerts anti-viral functions. This chemokine is constitutively expressed in the respiratory tract, suggesting a role in lung defenses. However, little is known about the participation of CXCL17 against relevant respiratory pathogens in humans. Here, we evaluated the serum levels and lung tissue expression pattern of CXCL17 in a cohort of patients with severe pandemic influenza A(H1N1) from Mexico City. Peripheral blood samples obtained on admission and seven days after hospitalization were processed for determinations of serum CXCL17 levels by enzyme-linked immunosorbent assay (ELISA). The expression of CXCL17 was assessed by immunohistochemistry (IHQ) in lung autopsy specimens from patients that succumbed to the disease. Serum CXCL17 levels were also analyzed in two additional comparative cohorts of coronavirus disease 2019 (COVID-19) and pulmonary tuberculosis (TB) patients. Additionally, the expression of CXCL17 was tested in lung autopsy specimens from COVID-19 patients. A total of 122 patients were enrolled in the study, from which 68 had pandemic influenza A(H1N1), 24 had COVID-19, and 30 with PTB. CXCL17 was detected in post-mortem lung specimens from patients that died of pandemic influenza A(H1N1) and COVID-19. Interestingly, serum levels of CXCL17 were increased only in patients with pandemic influenza A(H1N1), but not COVID-19 and PTB. CXCL17 not only differentiated pandemic influenza A(H1N1) from other respiratory infections but showed prognostic value for influenza-associated mortality and renal failure in machine-learning algorithms and regression analyses. Using cell culture assays, we also identified that human alveolar A549 cells and peripheral blood monocyte-derived macrophages increase their CXCL17 production capacity after influenza A(H1N1) pdm09 virus infection. Our results for the first time demonstrate an induction of CXCL17 specifically during pandemic influenza A(H1N1), but not COVID-19 and PTB in humans. These findings could be of great utility to differentiate influenza and COVID-19 and to predict poor prognosis specially at settings of high incidence of pandemic A(H1N1). Future studies on the role of CXCL17 not only in severe pandemic influenza, but also in seasonal influenza, COVID-19, and PTB are required to validate our results.

SummarySustainable Development Goal 2.2.2, to end malnutrition by 2030, measures progress through elimination of child wasting, defined as weight-for-length more than 2 standard deviations below international standards. Prevailing methods to measure wasting rely on cross-sectional surveys that cannot measure onset, recovery, and persistence — key features of wasting epidemiology that could inform preventive interventions and disease burden estimates. Here, we show through an analysis of 21 longitudinal cohorts that wasting is a highly dynamic process of onset and recovery, and incidence peaks between birth and 3 months — far earlier than peak prevalence at 12-15 months. By age 24 months 29.2% of children had experienced at least one wasting episode, more than 5-fold higher than point prevalence (5.6%), demonstrating that wasting incidence is far higher than cross-sectional surveys suggest. Children wasted before 6 months were more likely to experience concurrent wasting and stunting (low height-for-age) later, increasing their risk of mortality. In diverse populations with seasonal rainfall, population average weight-for-length varied substantially (>0.5 z in some cohorts), with the lowest mean Z-scores during the rainiest months, creating potential for seasonally targeted interventions. Our results motivate a new focus on extending preventive interventions for wasting to pregnant and lactating mothers, and for preventive and therapeutic interventions to include children below age 6 months in addition to current targets of ages 6-59 months.

SummaryGrowth faltering (low length-for-age or weight-for length) in the first 1000 days — from conception to two years of age — influences both short and long-term health and survival. Evidence for interventions to prevent growth faltering such as nutritional supplementation during pregnancy and the postnatal period has increasingly accumulated, but programmatic action has been insufficient to eliminate the high burden of stunting and wasting in low- and middle-income countries. In addition, there is need to better understand age-windows and population subgroups in which to focus future preventive efforts. Here, we show using a population intervention effects analysis of 33 longitudinal cohorts (83,671 children) and 30 separate exposures that improving maternal anthropometry and child condition at birth, in particular child length-at-birth, accounted for population increases by age 24 months in length-for-age Z of 0.04 to 0.40 and weight-for-length Z by 0.02 to 0.15. Boys had consistently higher risk of all forms of growth faltering than girls, and early growth faltering predisposed children to subsequent and persistent growth faltering. Children with multiple growth deficits had higher mortality rates from birth to two years than those without deficits (hazard ratios 1.9 to 8.7). The importance of prenatal causes, and severe consequences for children who experienced early growth faltering, support a focus on pre-conception and pregnancy as key opportunities for new preventive interventions.

Habitat loss has major impacts on biodiversity. Yet, such impacts are not always linear, as there can be threshold values of habitat amount below which species become extirpated from human-modified landscapes (extinction thresholds). This may be particularly the case for species with high habitat spatial requirements, especially in regions with a long land-use history, which have a lower extinction debt. To address these issues, we evaluated the linear and non-linear effects of landscape-scale forest (habitat) loss on primate species richness in regions with relatively new (Amazon) and old (Atlantic Forest) histories of land-use change. We also evaluated the role of mean home range size in regulating species responses to forest loss. Extinction thresholds were higher in the Atlantic Forest (78% remaining forest cover) than in the Amazon (45%), but primate-landscape associations were stronger in the Amazon. Thus, despite its recent land-use history, Amazon primates are more sensitive to habitat loss. As predicted, mean home range size decreased with forest loss in both biomes. Our findings highlight the importance of stopping deforestation in both biomes to maintain habitat amount above these thresholds. Yet, as

Teachers in urban schools experience stress and burnout at levels that significantly impact their mental health and occupational functioning, and contribute to alarming rates of attrition. The current mixed-methods study employed a sample of 162 predominantly White and female urban teachers in the United States to examine the role of personal and contextual factors, and responses to situational challenges, in predicting burnout. Results revealed that multiple personal factors and responses to situational challenges predicted burnout. Notably, higher levels of professional and social-emotional support predicted lower levels of burnout across multiple dimensions, while internal locus of control and digestive responses to situational challenges, respectively, predicted higher levels of Personal Accomplishment and Emotional Exhaustion. Implications include further avenues of research and suggestions for supports which function as teacher resources in the mitigation of burnout and promotion of wellbeing for urban teachers.

El propósito fundamental de esta investigación fue documentar el uso de especies vegetales en la práctica culinaria de la parroquia El Anegado, con un enfoque destacado en su aplicabilidad como alimentos, condimentos y bebidas, especialmente relevantes para los visitantes. Para alcanzar este objetivo, se emplearon discusiones grupales, entrevistas y diálogos con los residentes locales, con el fin de capturar y documentar su conocimiento sobre las plantas utilizadas en la cocina tradicional. Se logró identificar un total de 41 especies, abarcando 24 familias de relevancia gastronómica. La mayoría de estas especies son cultivadas, reflejando la interacción activa entre las comunidades locales y el entorno natural circundante. Entre las familias destacan Fabaceae y Rutaceae, que sobresalen por albergar un mayor número de especies de interés culinario. Se registró 74 usos gastronómicos, distribuidos en tres categorías principales: bebidas (29), plantas comestibles (27) y condimentos (18). Es importante notar que una misma especie puede ser aprovechada para diversos fines culinarios. Resulta llamativa la importancia atribuida a especies como Musa paradisiaca y Zea mays, que constituyen la base fundamental de numerosos platos característicos de la gastronomía local. La variedad de especies identificadas y los usos atribuidos a ellas revelan una interacción rica y arraigada entre la comunidad y su entorno natural. La preservación de estas prácticas culinarias no solo enriquece la experiencia gastronómica, sino que también promueve la conservación de la biodiversidad local y la preservación de tradiciones valiosas.
