RICORS2040 : The need for collaborative research in chronic kidney disease

Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is 'solved' by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020-2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true

Predation on Alouatta guariba clamitans Cabrera (Primates, Atelidae) by Leopardus pardalis (Linnaeus) (Carnivora, Felidae)

There are a few studies about predation on primates. Howler monkeys, being relatively large animals, were believed to be preyed on successfully only by medium to large-sized carnivores and large birds of prey. Our study took place at Chácara Payquerê, which is situated in the municipality of Balsa Nova, State of Paraná, Southern Brazil. Fingers and nails from Alouatta guariba clamitans Cabrera, 1940 were founded in two faecal samples from Leopardus pardalis (Linnaeus, 1758). With our documentation large howler monkey remains in faeces, the possibility of ocelot being a potential predator of all Neotropical primates should be taken into consideration.<br>São poucos os estudos sobre a predação de primatas. Sendo os bugios animais relativamente grandes, acredita-se que somente médios e grandes carnívoros e grandes rapineiros possam lograr sucesso em sua predação. O estudo foi realizado na Chácara Payquerê, situada no município de Balsa Nova, Estado do Paraná, sul do Brasil. Dedos e unhas de Alouatta guariba clamitans Cabrera, 1940 foram encontradas em duas amostras fecais de Leopardus pardalis (Linnaeus, 1758) que foram coletadas. Com este registro de grande primata em fezes, a possibilidade de a jaguatirica ser um potencial predador de todos os primatas neotropicais pode ser levada em consideração

Three years on demography of a group of Alouatta guariba clamitans Cabrera (Primates, Atelidae): growth and fragmentation

This study was carried out in the Chácara Payquerê do Bugre, State of Paraná, Southern Brazil (25º29'52" S and 49º39'24" W) and reports on the demography of a group of Alouatta guariba clamitans Cabrera, 1940 followed monthly during three years (from February, 2002 to March, 2005). The growth and subsequent fission of the group are described and argued, as well as their possible underlying causes, focusing on the population ecology and social behavior of this taxa.<br>Este estudo foi realizado na Chácara Payquerê do Bugre, Estado do Paraná, Sul do Brasil (25º29'52" S e 49º39'24" W), registrando aspectos da demografia de um grupo de Alouatta guariba clamitans Cabrera, 1940 acompanhado mensalmente durante três anos (de fevereiro de 2002 a março de 2005). O crescimento e a subseqüente fissão do grupo são descritos e discutidos, bem como suas possíveis causas, enfocando a ecologia populacional e o comportamento social deste taxa

Interação com os pais e o uso do espaço por um infante de Alouatta fusca (Geoffroy Saint-Hilaire, 1812) em cativeiro Interaction with parents and use of space by an infant of Alouatta fusca (Geoffroy Saint Hilaire, 1812) in captivity

Os primatas são animais que possuem elo social entre a mãe e sua prole, diferente de outras ordens de mamíferos. A sobrevivência do infante primata é completamente dependente do cuidado provido por membros de seu grupo social, particularmente do cuidado materno. O objetivo deste estudo foi analisar a utilização do recinto por um infante de bugio e sua proximidade com os pais. O grupo de bugios era composto por um casal de adultos e seu filhote fêmea com quatro meses de idade. O período de observações foi de agosto a dezembro/2006, perfazendo uma média de 96 horas de esforço de amostragem. O método de observação foi o animal focal com registro instantâneo, com intervalos de 30 segundos durante uma hora por dia. O local do estudo foi o recinto de exposição da Fundação Zoo-Botânica de Belo Horizonte, com 7m de altura, 6 m de largura, 7 m de profundidade com presença de paisagismo interno. As observações revelaram um contato maior do infante com a mãe em relação ao pai e um distanciamento significativo (P < 0,05) do filhote em relação ao contato materno, com o aumento da idade e maior independência. O local mais utilizado durante os três primeiros meses de cativeiro foi a pérgola. No mês de dezembro, período de maior pluviosidade, o filhote aumentou interações ventrais com a mãe, e permaneceu mais tempo no cano. As informações obtidas neste trabalho contribuem para um melhor entendimento em relação aos infantes de Alouatta fusca, suas interações sociais e uso do espaço que podem ser utilizados para aprimorar o manejo ex-situ dos animais, criando melhores condições para a estadia dos mesmos em cativeiro, utilizando-se de estruturas adequadas que simulem o ambiente natural, a fim de garantir o bem-estar dos bugios e assim, a sobrevivência da espécie.<br>Primates are social animals that have bond between mother and offspring, unlike other orders of mammals. The survival of an infant primate is completely dependent on the care provided by members of their social group, particularly maternal care. The aim of this study was to analyze the use of premises for an infant of monkey and its proximity to the parents. The group of monkeys was composed of a pair of adult female and her pup at 4 months of age. The observation period was from august to december 2006, making an average of 96 hours of sampling effort. The method of observation was the focal animal with instant record, with 30 second intervals for 1 hour per day. The study site was an exhibition space of the Zoo-Botanical Foundation of Belo Horizonte, 7 m high, 6 m wide, 7 m deep with the presence of internal landscaping. The results revealed greater contact with the infant's mother and father in relation to a significant departure (P < 0.05) compared to the puppy's maternal contact with increasing age and greater independence. The most used during the first 3 months of captivity was the pergola. In December, a period of higher rainfall, the chick ventral increased interactions with the mother, and stayed longer in the barrel. Information obtained here will contribute to a better understanding in relation to infants of Alouatta fusca, their social interactions and use of space that can be used to improve the ex-situ management of animals, creating better conditions for the stay of those in captivity, using appropriate structures that mimic the natural environment, to ensure the welfare of apes and thus the survival of the species
