Amazonian ecosystems are major biodiversity hotspots and carbon sinks that may lose species to extinction and become carbon sources due to extreme dry or warm conditions. We investigated the seasonal patterns of high-resolution solar-induced chlorophyll fluorescence (SIF) measured by the satellite Orbiting Carbon Observatory-2 (OCO-2) across the Amazonian ecoregions to assess the area´s phenology and extreme drought vulnerability. SIF is an indicator of the photosynthetic activity of chlorophyll molecules and is assumed to be directly related to gross primary production (GPP). We analyzed SIF variability in the Amazon basin during the period between September 2014 and December 2018. In particular, we focused on the SIF drought response under the extreme drought period during the strong El Niño in 2015–2016, as well as the 6-month drought peak period. During the drought´s peak months, the SIF decreased and increased with different intensities across the ecoregions of the Amazonian moist broadleaf forest (MBF) biome. Under a high temperature, a high vapor pressure deficit, and extreme drought conditions, the SIF presented differences from −31.1% to +17.6%. Such chlorophyll activity variations have been observed in plant-level measurements of active fluorescence in plants undergoing physiological responses to water or heat stress. Thus, it is plausible that the SIF variations in the ecoregions’ ecosystems occurred as a result of water and heat stress, and arguably because of drought-driven vegetation mortality and collateral effects in their species composition and community structures. The SIF responses to drought at the ecoregional scale indicate that there are different levels of resilience to drought across MBF ecosystems that the currently used climate- and biome-region scales do not capture. Finally, we identified monthly SIF values of 32 ecoregions, including non-MBF biomes, which may give the first insights into the photosynthetic activity dynamics of Amazonian ecoregions.

Purpose The aim of this study was to carry out a systematic review of telemedicine technology and to discuss the role of legislation in the application of telemedicine technology within the scope of COVID-19. Methods The search for papers was conducted in the databases Cochrane Central, MEDLINE, and Embase. The keywords considered for this systematic review were (coronavirus OR “2019-nCoV” OR 2019nCoV OR nCoV2019 OR “nCoV-2019” OR “COVID-19” OR COVID19 OR “HCoV-19” OR HCoV19 OR CoV OR “2019 novel*” OR Ncov OR “n-cov” OR “SARS-CoV-2” OR “SARSCoV-2” OR “SARSCoV2” OR “SARSCoV2” OR SARSCov19 OR “SARS-Cov19” OR “SARS-Cov-19” OR “severe acute respiratory syndrome*” OR ((corona* OR corono*) AND (virus* OR viral* OR virinae*))) AND ((telemedicine OR telehealth OR “remote assessment” OR telemonitoring)). The review process was carried out by six independent reviewers, using the PRISMA-P method. Results As a result, a total of 34 papers were selected, which addressed the study of telemedicine technologies used in times of endemics, epidemics, and pandemics, focusing on COVID-19. Conclusion Telemedicine allows for care in remote areas and at a lower cost to the patient and, in the current situation, it can reduce the number of contagions as well as the occupation of beds in health facilities. Telemedicine may suffer from limitations, mainly due to current legislation, but in this pandemic era of COVID-19, several countries around the world have made their laws more flexible to allow more widespread use of telemedicine.

Purpose COVID-19 has spread and continues to spread rapidly across the world. There is still no approved and effective treatment for the disease. Several drugs are being administered empirically to patients, based on results from studies with limited methodologies. There is an urgent need for systematic reviews to support decision makers and the development of guidelines. The purpose of this paper was to conduct a systematic review of drug studies carried out worldwide for COVID-19, verifying the effectiveness and methodological quality. Method The search for relevant articles was performed in the Cochrane Central, MEDLINE, and Embase databases. The terms and combinations used for the search were ((
