La realidad de las personas trans en el contexto de la pandemia: el caso de Argentina y México

El presente trabajo tiene por finalidad identificar, a partir de los casos particulares de Argentina y México, el impacto que han implicado la pandemia por el Covid-19, y las políticas públicas de prevención que se dictaron al efecto, en la comunidad travesti/trans. Para ello retomaremos las estructuras analizadas en los informes internacionales, con la finalidad de poder individualizar no solo las problemáticas presentes en estos colectivos en los dos países, sino los paliativos y soluciones que fueron puestas en marcha tanto por parte de los Estados, como por la sociedad civil. Las categorías que desarrollaremos tienen que ver con las relaciones interpersonales, los cuidados de la salud, los problemas económicos y financieros, la discriminación social e institucional y las políticas estatales anti-LGTBIQ+ que han sido desarrolladas en el contexto de la pandemia.Instituto de Relaciones Internacionale

Ancient marine sediment DNA reveals diatom transition in Antarctica

Antarctica is one of the most vulnerable regions to climate change on Earth and studying the past and present responses of this polar marine ecosystem to environmental change is a matter of urgency. Sedimentary ancient DNA (sedaDNA) analysis can provide such insights into past ecosystem-wide changes. Here we present authenticated (through extensive contamination control and sedaDNA damage analysis) metagenomic marine eukaryote sedaDNA from the Scotia Sea region acquired during IODP Expedition 382. We also provide a marine eukaryote sedaDNA record of ~1 Mio. years and diatom and chlorophyte sedaDNA dating back to ~540 ka (using taxonomic marker genes SSU, LSU, psbO). We find evidence of warm phases being associated with high relative diatom abundance, and a marked transition from diatoms comprising <10% of all eukaryotes prior to ~14.5 ka, to ~50% after this time, i.e., following Meltwater Pulse 1A, alongside a composition change from sea-ice to openocean species. Our study demonstrates that sedaDNA tools can be expanded to hundreds of thousands of years, opening the pathway to the study of ecosystem-wide marine shifts and paleo-productivity phases throughout multiple glacial-interglacial cycles.Antarctica is one of the most vulnerable regions to climate change on Earth and studying the past and present responses of this polar marine ecosystem to environmental change is a matter of urgency.

Out-of-pocket cost for medical care of injured patients presenting to emergency department of national hospital in Tanzania: a prospective cohort study

OBJECTIVE: We aimed to determine the out-of-pocket (OOP) costs for medical care of injured patients and the proportion of patients encountering catastrophic costs. DESIGN: Prospective cohort study SETTING: Emergency department (ED) of a tertiary-level hospital in Dar es Salaam, Tanzania. PARTICIPANTS: Injured adult patients seen at the ED of Muhimbili National Hospital from August 2019 to March 2020. METHODS: During alternating 12-hour shifts, consecutive trauma patients were approached in the ED after stabilisation. A case report form was used to collect social-demographics and patient clinical profile. Total charges billed for ED and in-hospital care and OOP payments were obtained from the hospital billing system. Patients were interviewed by phone to determine the measures they took to pay their bills. PRIMARY OUTCOME MEASURE: The primary outcome was the proportion of patients with catastrophic health expenditure (CHE), using the WHO definition of OOP expenditures ≥40% of monthly income. RESULTS: We enrolled 355 trauma patients of whom 51 (14.4%) were insured. The median age was 32 years (IQR 25-40), 238 (83.2%) were male, 162 (56.6%) were married and 87.8% had ≥2 household dependents. The majority 224 (78.3%) had informal employment with a median monthly income of US$86. Overall, 286 (80.6$176.98 (IQR 62.33-311.97). Chest injury and spinal injury incurred the highest OOP payments of US$282.63 (84.71-369.33) and 277.71 (191.02-874.47), respectively. Overall, 85.3% had a CHE. 203 patients (70.9%) were interviewed after discharge. In this group, 13.8% borrowed money from family, and 12.3% sold personal items of value to pay for their hospital bills. CONCLUSION: OOP costs place a significant economic burden on individuals and families. Measures to reduce injury and financial risk are needed in Tanzania

Clinical profile and outcomes of paediatric patients with acute seizures: a prospective cohort study at an urban emergency department of a tertiary hospital in Tanzania

OBJECTIVE: Children with seizures require immediate and appropriate intervention in the emergency department (ED). This study describes the clinical profile and outcome of paediatric patients with seizures at the ED in a country with limited resources. DESIGN: A prospective, observational cohort study of paediatric patients with seizure presenting to an ED conducted over a six-month period from 1 August 2019 to 31 January2020. SETTING: The study was conducted at the ED of Muhimbili National Hospital, a level 1 trauma centre located in Dar es Salaam, Tanzania. PARTICIPANTS: Paediatric patients aged 1 month to 14 years presenting at the ED with acute seizure, defined as any seizure occurring from 24 hours to 7 days prior to the visit, were included in this study. Patients were consecutively enrolled during times a research assistant was present in the department. Newborns, children with repeat visits or no signs of life on arrival were excluded. OUTCOME: The primary outcome was the proportion of paediatric patients presenting with seizures and their mortality rate; secondary outcome was risk factors for mortality. RESULT: During the study period, 1011 children were seen in the department, of whom 114 (11.3%) (95% CI 9.3% to 13.3%) presented with seizures. Median age was 24 months (IQR 9-60), 78.1% were under 5 years and 55.3% were males. The majority 76 (66.7%) of the patients presented with generalised seizures. Half 58 (50.9%) of patients presented with fever. Meningitis was the most common aetiology, diagnosed in 30 (26.3%). Overall mortality was 16.7% (95% CI 10.3% to 24.8%). Using negative log binominal analysis, fever (relative risk, RR 2.7), altered mental status (RR 21.1), hypoxia (RR 3.3), abnormal potassium (RR 2.4) and clinical diagnosis of meningitis (RR 3.4) were statistically significantly associated with mortality. CONCLUSIONS: Findings from this study revealed higher incidence of paediatric patients with seizures than that reported in high-income countries and other low-income and middle-income countries. The acuity of illness was high, with 16.7% mortality rate. The presence of fever, altered mental status, hypoxia, abnormal potassium levels and meningitis diagnosis were associated with higher risk of mortality. Further research is needed to develop interventions to improve outcomes in paediatric patients with seizures in our setting

Tropical and Boreal Forest Atmosphere Interactions: A Review

This review presents how the boreal and the tropical forests affect the atmosphere, its chemical composition, its function, and further how that affects the climate and, in return, the ecosystems through feedback processes. Observations from key tower sites standing out due to their long-term comprehensive observations: The Amazon Tall Tower Observatory in Central Amazonia, the Zotino Tall Tower Observatory in Siberia, and the Station to Measure Ecosystem-Atmosphere Relations at Hyytiala in Finland. The review is complemented by short-term observations from networks and large experiments.The review discusses atmospheric chemistry observations, aerosol formation and processing, physiochemical aerosol, and cloud condensation nuclei properties and finds surprising similarities and important differences in the two ecosystems. The aerosol concentrations and chemistry are similar, particularly concerning the main chemical components, both dominated by an organic fraction, while the boreal ecosystem has generally higher concentrations of inorganics, due to higher influence of long-range transported air pollution. The emissions of biogenic volatile organic compounds are dominated by isoprene and monoterpene in the tropical and boreal regions, respectively, being the main precursors of the organic aerosol fraction.Observations and modeling studies show that climate change and deforestation affect the ecosystems such that the carbon and hydrological cycles in Amazonia are changing to carbon neutrality and affect precipitation downwind. In Africa, the tropical forests are so far maintaining their carbon sink.It is urgent to better understand the interaction between these major ecosystems, the atmosphere, and climate, which calls for more observation sites, providing long-term data on water, carbon, and other biogeochemical cycles. This is essential in finding a sustainable balance between forest preservation and reforestation versus a potential increase in food production and biofuels, which are critical in maintaining ecosystem services and global climate stability. Reducing global warming and deforestation is vital for tropical forests
