RESUMO
Primates, represented by 521 species, are distributed across 91 countries primarily in the Neotropic, Afrotropic, and Indo-Malayan realms. Primates inhabit a wide range of habitats and play critical roles in sustaining healthy ecosystems that benefit human and nonhuman communities. Approximately 68% of primate species are threatened with extinction because of global pressures to convert their habitats for agricultural production and the extraction of natural resources. Here, we review the scientific literature and conduct a spatial analysis to assess the significance of Indigenous Peoples' lands in safeguarding primate biodiversity. We found that Indigenous Peoples' lands account for 30% of the primate range, and 71% of primate species inhabit these lands. As their range on these lands increases, primate species are less likely to be classified as threatened or have declining populations. Safeguarding Indigenous Peoples' lands, languages, and cultures represents our greatest chance to prevent the extinction of the world's primates.
RESUMO
The Covid-19 pandemic has been responsible for millions of deaths worldwide. Patients with comorbidities- such as those on peritoneal dialysis (PD)- present higher morbidity and mortality than the general population. We prospectively evaluated all Chilean patients on PD (48 centres) and followed those who had Covid-19 from the beginning of the Covid-19 pandemic in Chile (March 2020) to January 2021 (start of vaccination campaign). We described demographic history, comorbidities, factors related to infection, need for hospitalisation and death due to Covid-19. During the study period, 106 adults on PD were infected by SARS-CoV-2, with a mean age of 53.1 (±16.3) and of which 53.9% were female. From that group, 54.8% required hospitalisation and 24.5% (n = 26) died due to Covid-19. Most of the patients (63.4%) were infected at home and 22.8% during hospitalisation for other reasons. There was a significant association for Covid-19 mortality with: being ≥60 years old, diabetes, time on PD ≥5 years, need for hospitalisation and hospital-acquired infection. At 90 days of follow-up, all deaths associated to Covid-19 occurred before 40 days. We conclude that patients on PD without Covid-19 vaccination have a high mortality and need for hospitalisation associated to Covid-19. To avoid this negative outcome, it is necessary to intensify strategies to avoid contagion, especially in those ≥60 years old, with diabetes and/or ≥5 years spent on PD.

Primates occur in 90 countries, but four-Brazil, Madagascar, Indonesia, and the Democratic Republic of the Congo (DRC)-harbor 65% of the world's primate species (439) and 60% of these primates are Threatened, Endangered, or Critically Endangered (IUCN Red List of Threatened Species 2017-3). Considering their importance for global primate conservation, we examine the anthropogenic pressures each country is facing that place their primate populations at risk. Habitat loss and fragmentation are main threats to primates in Brazil, Madagascar, and Indonesia. However, in DRC hunting for the commercial bushmeat trade is the primary threat. Encroachment on primate habitats driven by local and global market demands for food and non-food commodities hunting, illegal trade, the proliferation of invasive species, and human and domestic-animal borne infectious diseases cause habitat loss, population declines, and extirpation. Modeling agricultural expansion in the 21st century for the four countries under a worst-case-scenario, showed a primate range contraction of 78% for Brazil, 72% for Indonesia, 62% for Madagascar, and 32% for DRC. These pressures unfold in the context of expanding human populations with low levels of development. Weak governance across these four countries may limit effective primate conservation planning. We examine landscape and local approaches to effective primate conservation policies and assess the distribution of protected areas and primates in each country. Primates in Brazil and Madagascar have 38% of their range inside protected areas, 17% in Indonesia and 14% in DRC, suggesting that the great majority of primate populations remain vulnerable. We list the key challenges faced by the four countries to avert primate extinctions now and in the future. In the short term, effective law enforcement to stop illegal hunting and illegal forest destruction is absolutely key. Long-term success can only be achieved by focusing local and global public awareness, and actively engaging with international organizations, multinational businesses and consumer nations to reduce unsustainable demands on the environment. Finally, the four primate range countries need to ensure that integrated, sustainable land-use planning for economic development includes the maintenance of biodiversity and intact, functional natural ecosystems.
RESUMO
Nonhuman primates, our closest biological relatives, play important roles in the livelihoods, cultures, and religions of many societies and offer unique insights into human evolution, biology, behavior, and the threat of emerging diseases. They are an essential component of tropical biodiversity, contributing to forest regeneration and ecosystem health. Current information shows the existence of 504 species in 79 genera distributed in the Neotropics, mainland Africa, Madagascar, and Asia. Alarmingly, ~60% of primate species are now threatened with extinction and ~75% have declining populations. This situation is the result of escalating anthropogenic pressures on primates and their habitats-mainly global and local market demands, leading to extensive habitat loss through the expansion of industrial agriculture, large-scale cattle ranching, logging, oil and gas drilling, mining, dam building, and the construction of new road networks in primate range regions. Other important drivers are increased bushmeat hunting and the illegal trade of primates as pets and primate body parts, along with emerging threats, such as climate change and anthroponotic diseases. Often, these pressures act in synergy, exacerbating primate population declines. Given that primate range regions overlap extensively with a large, and rapidly growing, human population characterized by high levels of poverty, global attention is needed immediately to reverse the looming risk of primate extinctions and to attend to local human needs in sustainable ways. Raising global scientific and public awareness of the plight of the world's primates and the costs of their loss to ecosystem health and human society is imperative.

El propósito del estudio fue evaluar el efecto de habilitación lingüística en los modos activos del lenguaje señalar, hablar y escribir a partir del modo reactivo observar. Participaron 15 estudiantes experimentalmente ingenuos, doce hombres y tres mujeres, de 14 años de edad, alumnos de tercer grado de una escuela secundaria pública de la ciudad de Xalapa. Se utilizó un arreglo experimental de igualación de la muestra de segundo orden con figuras geométricas y un diseño experimental de tres grupos con prueba inicial, fase de familiarización, fase de exposición y prueba de habilitación. Los resultados sugieren que la exposición al modo observar habilitó las respuestas de igualación en los tres modos activos del lenguaje con distintos niveles de ejecución. El máximo nivel se obtuvo en hablar, el segundo en escribir y el mínimo en señalar. El porcentaje de respuestas de discriminación fue un poco más alto en semejanza en color, seguido por diferencia en color y forma, y un poco más bajo en semejanza en forma. Los resultados se discuten con base en el concepto de habilitación lingüística.
The purpose of the study was to assess the effect of enabling linguistic active modes of language by pointing out, writing and speaking from the reactive mode observing. Participants were 15 experimentally naive students, twelve men and three women, aged 14, who attended third grade in a public Junior High School in the city of Xalapa. A second-order matching to sample task with geometric figures was used. The design chosen was experimental with three groups and consisted of an initial test, familiarization phase, exposure phase and final test. The results suggest that the exposure to the observing mode enabled the matching responses in the three active modes of language with different performance levels. The largest level was speaking, then was writing and the lower was pointing out. The percentage of response discrimination was slightly higher in color similarity, followed by the difference in color and form and slightly lower percentage in shape similarity. The results are discussed based on the concept of enabling linguistic modes.

OBJECTIVE: Obesity in children and adolescents is associated to a morbidity that has increased significantly. It has become a public health problem around the world. The objective of this paper was to evaluate the efficacy of the cognitive behavioral treatment strategy in the comprehensive management of obesity in adolescents. METHODS: Double blind, randomized, and controlled intervention study, of four months of follow-up, with a total of 115 obese adolescents, aged 12 to 16 years. The intervention group received cognitive behavioral treatment strategy, as well as advise on diet and exercise. At the same time, the control group only received advise on diet and exercise. RESULTS: The percentage of adolescents who showed adherence to diet was 73.7 % versus 41.4 %, (p = 0.0009) and to exercise, 61.4 % versus 19.0 %, (p < 0.0005); compared with the control group, the intervention group was significantly higher. A total of 10 adolescents (17.5 %) in the intervention group and 26 (44.8 %) in the control group dropped-out (p = 0.003). Despite there were significant differences between groups, adolescents in the intervention group exhibited a higher and sustained decrease in body weight, body mass index, as well as in the body fat percentage. CONCLUSIONS: The cognitive behavioral treatment strategy improves adherence and decreases desertion of the weight reduction program in adolescents.
INTRODUCTIÓN: la obesidad en niños y adolescentes y la morbilidad que se le asocia se han incrementado significativamente, lo cual se ha convertido en un problema de salud pública. El objetivo de este estudio fue evaluar la eficacia de la terapia cognitivo-conductual (TCC) en el manejo integral de la obesidad en adolescentes. MÉTODOS: estudio de intervención, aleatorio, doble ciego, controlado, de cuatro meses de seguimiento, al que se integraron 115 adolescentes obesos de 12 a 16 años de edad. El grupo de intervención recibió TCC como terapia coadyuvante, así como indicaciones de dieta y apoyo para el desarrollo de ejercicio. El grupo control solo recibió indicaciones de dieta y apoyo para el desarrollo de ejercicio. RESULTADOS: el porcentaje de adolescentes que se adhirieron a las indicaciones de dieta (73.7 % frente a 41.4 %, p = 0.0009) y ejercicio (61.4 % frente a 19.0 %, p < 0.0005) fue significativamente mayor en el grupo que recibió TCC. En este grupo se registraron 10 pérdidas (17.5 %) y en el grupo control 26 (44.8 %), p = 0.003. Aun cuando hubo diferencias significativas entre los grupos, en los adolescentes que recibieron TCC se apreció una disminución mayor y sostenida tanto en el peso corporal y el IMC como en el porcentaje de grasa total. CONCLUSIÓN: la TCC mejora la adherencia y disminuye la deserción de un programa para reducción de peso en adolescentes.
