SARS-CoV-2, the etiological agent of COVID-19 was first described in Wuhan in December 2019 and has now spread globally. Ecuador was the second country in South America to report confirmed cases. The first case reported in Quito, the capital city of Ecuador, was a tourist who came from the Netherlands and presented symptoms on March 10th, 2020 (index case). In this work we used the MinION platform (Oxford Nanopore Technologies) to sequence the metagenome of the bronchoalveolar lavage (BAL) from this case reported, and subsequently we sequenced the whole genome of the index case and other three patients using the ARTIC network protocols. Our data from the metagenomic approach confirmed the presence of SARS-CoV-2 coexisting with pathogenic bacteria suggesting coinfection. Relevant bacteria found in the BAL metagenome were Streptococcus pneumoniae, Mycobacterium tuberculosis, Staphylococcus aureus and Chlamydia spp. Lineage assignment of the four whole genomes revealed three different origins. The variant HEE-01 was imported from the Netherlands and was assigned to B lineage, HGSQ-USFQ-018, belongs to the B.1 lineage showing nine nucleotide differences with the reference strain and grouped with sequences from the United Kingdom, and HGSQ-USFQ-007 and HGSQ-USFQ-010 belong to the B lineage and grouped with sequences from Scotland. All genomes show mutations in their genomes compared to the reference strain, which could be important to understand the virulence, severity and transmissibility of the virus. Our findings also suggest that there were at least three independent introductions of SARS-CoV-2 to Ecuador. IMPORTANCE: COVID-19, an infectious disease caused by SARS-CoV-2, has spread globally including Latin American countries including Ecuador. The first strain of SARS-CoV-2 sequenced was from Wuhan, which is considered as the reference strain. There were no data about the SARS-CoV-2 lineages in Ecuador, and the purpose of this study was to find out the origin of the different lineages circulating in the population. We also were interested in the mutations present in these genomes as they can influence virulence, transmission and infectivity.

Intensive care medicine is a relatively young discipline that has rapidly grown into a full-fledged medical subspecialty. Intensivists are responsible for managing an ever-increasing number of patients with complex, life-threatening diseases. Several factors may influence their performance, including age, training, experience, workload, and socioeconomic context. The aim of this study was to examine individual- and work-related aspects of the Latin American intensivist workforce, mainly with academic appointments, which might influence the quality of care provided. In consequence, we conducted a cross-sectional study of intensivists at public and private academic and nonacademic Latin American intensive care units (ICUs) through a web-based electronic survey submitted by email. Questions about personal aspects, work-related topics, and general clinical workflow were incorporated. Our study comprised 735 survey respondents (53% return rate) with the following country-specific breakdown: Brazil (29%); Argentina (19%); Chile (17%); Uruguay (12%); Ecuador (9%); Mexico (7%); Colombia (5%); and Bolivia, Peru, Guatemala, and Paraguay combined (2%). Latin American intensivists were predominantly male (68%) young adults (median age, 40 [IQR, 35–48] years) with a median clinical ICU experience of 10 (IQR, 5–20) years. The median weekly workload was 60 (IQR, 47–70) h. ICU formal training was between 2 and 4 years. Only 63% of academic ICUs performed multidisciplinary rounds. Most intensivists (85%) reported adequate conditions to manage patients with septic shock in their units. Unsatisfactory conditions were attributed to insufficient technology (11%), laboratory support (5%), imaging resources (5%), and drug shortages (5%). Seventy percent of intensivists participated in research, and 54% read scientific studies regularly, whereas 32% read no more than one scientific study per month. Research grants and pharmaceutical sponsorship are unusual funding sources in Latin America. Although Latin American intensivists are mostly unsatisfied with their income (81%), only a minority (27%) considered changing to another specialty before retirement. Latin American intensivists constitute a predominantly young adult workforce, mostly formally trained, have a high workload, and most are interested in research. They are under important limitations owing to resource constraints and overt dissatisfaction. Latin America may be representative of other world areas with similar challenges for intensivists. Specific initiatives aimed at addressing these situations need to be devised to improve the quality of critical care delivery in Latin America.

Several risk factors were associated with mortality in patients with coronavirus disease 2019 (COVID-19) infection in intensive care units (ICU). We assessed the effect of risk factors related to the characteristics and clinical history of the population, laboratory test results, drug management, and type of ventilation on the probability of survival/discharge from the ICU. A retrospective cohort multicentric study of adults with COVID-19 admitted to the ICU between March 2020 and December 2021. Data were collected from 6 hospitals in 5 cities in Ecuador. The primary outcome was ICU survival/discharge. Survival analysis was conducted using semi-parametric Cox proportional hazards models. Of those admitted to the ICU with COVID-19, (n = 991), mean age was 56.76 ± 13.14, and 65.9% were male. Regarding the primary outcome, 51.1% (n = 506) died and 48.9% (n = 485) survived. Of the group that died, their mean age was higher than the survivors (60.7 vs 52.60 years, respectively), and they had a higher prevalence of comorbidities such as arterial hypertension (37.2% vs 20.4%, respectively) and diabetes mellitus (26.9% vs 15.7%, respectively), with P < .001. In ventilatory management, 32.7% of patients used noninvasive ventilation and high-flow nasal cannula, and 67.3% required invasive ventilatory support. After adjusting for confounders, Cox regression analysis showed that patients were less likely to be discharged alive from the ICU if they met the following conditions: arterial hypertension (hazard ratio [HR] = 0.83 95% CI 0.723–0.964), diabetes mellitus (HR = 0.80 95% CI 0.696–0.938), older than 62 years (HR = 0.86 95% CI 0.790–0.956), obese (body mass index ≥ 30) (HR = 0.78 95% CI 0.697–0.887), 1 unit increase in SOFA score (HR = 0.94 95% CI 0.937–0.961), PaO2/FiO2 ratio <100 mm Hg (HR = 0.84 95% CI 0.786–0.914), and the use of invasive mechanical ventilation (HR = 0.68 95% CI 0.614–0.769). Risk factors associated with increased mortality were older age, obesity, arterial hypertension, and diabetes. Factors such as male gender, chronic obstructive pulmonary disease, acute kidney injury, and cancer reported in other investigations did not have the same effect on mortality in our study.

BACKGROUND AND OBJECTIVES: Penetrating brain injury (PBI) is a highly lethal form of traumatic brain injury, with substantial mortality and marked differences across high-income countries and low- to middle-income countries. The aim of the Comparative Effectiveness Research in the Americas on Penetrating Brain Injury (COMPAS-PBI) study was to evaluate management variability, compare outcomes across resource settings, and assess the feasibility of real-time multinational neurocritical care data collection. METHODS: COMPAS-PBI is a multinational, multicenter observational comparative effectiveness study. It includes a retrospective cohort (2021-2025) and a prospective cohort (2026-2028) of adults aged 18 years or older with confirmed PBI, defined by radiographic evidence of dural penetration on head computed tomography, presenting within 24 hours of injury. Eleven trauma centers across 8 countries in the Americas will participate, with the University of Oklahoma Health Sciences Campus serving as the coordinating center. The principal management strategies compared are intracranial pressure monitoring vs no monitoring and neurosurgical intervention, primarily early decompressive craniectomy, vs medical management alone. Comparative analyses will use propensity score–based methods to address baseline confounding. EXPECTED OUTCOMES: The primary outcome is in-hospital mortality. Secondary outcomes include disposition at discharge, Glasgow Outcome Scale-Extended score (at discharge, 6, and 12 months), and timing of intracranial pressure monitoring and decompressive craniectomy. Feasibility outcomes will assess completeness, timeliness, and quality of prospective real-time data capture, particularly in resource-limited settings. DISCUSSION: COMPAS-PBI will generate the first multinational comparative effectiveness data sets focused on civilian PBI within the Americas. The study is expected to provide pragmatic evidence to inform context-sensitive care strategies, reduce practice differences, and support future collaborative neurotrauma research.
