    Aim: Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the highly biodiverse Andes. Regional syntheses of climate change impacts on vegetation are pivotal to identify and guide research priorities. Here we review current data, knowledge and uncertainties in past, present and future climate change impacts on vegetation in the Andes. Location: Andes. Taxon: Plants. Methods: We (i) conducted a literature review on Andean vegetation responses to past and contemporary climatic change, (ii) analysed future climate projections for different elevations and slope orientations at 19 Andean locations using an ensemble of model outputs from the Coupled Model Intercomparison Project 5, and (iii) calculated changes in the suitable climate envelope area of Andean biomes and compared these results to studies that used species distribution models. Results: Future climatic changes (2040–2070) are projected to be stronger at high-elevation areas in the tropical Andes (up to 4°C under RCP 8.5), while in the temperate Andes temperature increases are projected to be up to 2°C. Under this worst-case scenario, temperate deciduous forests and the grasslands/steppes from the Central and Southern Andes are predicted to show the greatest losses of suitable climatic space (30% and 17%–23%, respectively). The high vulnerability of these biomes contrasts with the low attention from researchers modelling Andean species distributions. Critical knowledge gaps include a lack of an Andean wide plant checklist, insufficient density of weather stations at high-elevation areas, a lack of high-resolution climatologies that accommodates the Andes' complex topography and climatic processes, insufficient data to model demographic and ecological processes, and low use of palaeo data for distribution modelling. Main conclusions: Climate change is likely to profoundly affect the extent and composition of Andean biomes. Temperate Andean biomes in particular are susceptible to substantial area contractions. There are, however, considerable challenges and uncertainties in modelling species and biome responses and a pressing need for a region-wide approach to address knowledge gaps and improve understanding and monitoring of climate change impacts in these globally important biomes.publishedVersio

    Objective: To conduct a systematic review of tuberculous lymphadenitis cases in children published until April 2022. Material and methods: Case reports of tuberculous lymphadenitis by M. tuberculosis in children were searched in Scopus, PubMed, Science Direct, Web of Science, LILACs, Ovid MEDLINE, EBSCO, and BMC Case Reports databases. Results: Forty-one reports were selected and a total of 46 patients were included. The majority were males (52,2%) of 8,5 (5-12) years old. The time of disease was 2 (1-5) months. The most frequent clinical manifestations were palpable lymphadenopathy (60,9%), fever (52,2%) and cough (26,1%). Weight loss (17,4%), scrofula (15,2%), respiratory distress (13%), hyporexia (13%), localized pain (13%), skin rash (13%), night sweats (4.3%), abdominal pain (4.3%) and jaundice (2,2%) were also founded. Cervical nodes were most frequently involved (71,4%). Only 17,4% were associated with lung involvement. PPD was positive in 77.1%, bacilloscopy in 17.2%, histopathology in 94,1% and culture in 58,8%. Conclusions: Tuberculous lymphadenitis in children was more frequent in boys, between 5 and 12 years, immunized by BCG and without known contact with tuberculosis. The principal symptoms were palpable lymphadenopathy, fever and cough. However, atypical symptoms were respiratory difficulty, localized pain, skin rash, abdominal pain, and jaundice. Cervical nodes were the most affected. The test with greatest sensitivity was the histopathological study which detected 94,1% of cases.Objetivo:  Realizar una revisión sistemática de casos de linfadenitis tuberculosa en niños publicados en la literatura hasta abril de 2022.
