ABSTRACT
OBJECTIVES: The COVID-19 pandemic led to a decline in donation and transplant programs worldwide. Telehealth was explored as a strategy to continue organ procurement activity. The aim of this project was to develop and test I-DTI, an online medical platform for health care professionals specialized in the field of organ donation and transplant, that provides second-opinion consultancy and instant-messaging services. MATERIALS AND METHODS: The Donation and Transplantation Institute (DTI Foundation), in collaboration with the developers of an operative communication engine (Medxat/Be-Hit), designed the I-DTI platform, via a web-based application. I-DTI contents were created by the DTI Foundation medical team and international experts in organ donation and transplantation. I-DTI was launched in 2020 in a 6-month pilot phase, in which hospitals from India (Kerala), Philippines, Trinidad and Tobago, and Sri Lanka were included. In the pilot phase, about 60 health care professionals were involved and >20 international experts were enrolled to respond to incoming inquiries. The following topics were considered for this review: organ donation, organ transplantation, transplant follow-up, tissue donation, and COVID-19. Data collected were entered anonymously into an encrypted database for academic purposes. A survey was then conducted for all users to improve its acceptance and feasibility. RESULTS: On average, the second-opinion service was consulted 2 times per week by the participants, and experts' opinions were delivered in <24 hours. An intuitive user interface led participants to use the messaging service daily. Active dissemination contributed to I-DTI growth, achieving 300 users from >20 countries within the first year. CONCLUSIONS: I-DTI has proved to be a feasible tool to support health care professionals, for knowledge exchange and communication, ensuring access to international best practices. Nevertheless, it is imperative that medical providers actively encourage the use of innovative solutions available, especially in the areas with restricted access to knowledge.

BACKGROUND AND OBJECTIVES: Currently, the patient's baseline situation is a more important prognostic factor than age. The purpose of this study is to estimate the prognostic value of the ISAR score (Identification of Senior at Risk) in patients ≥75 years admitted to intensive care (ICU). PATIENTS AND METHODS: Prospective multicenter study including patients ≥75 years admitted to the ICU > 24hours. On admission, 28 days and 6 months after discharge from the ICU, mortality and baseline were evaluated using the ISAR score, the Lawton and Brody scale (LB) and the Barthel index (BI), the Frail fragility scale. scale (FS), the Charlson comorbidity index (ICC), Dementia rating score (DRC). RESULTS: 38 of 94 patients (40%) were high risk (ISAR ≥ 3) and were characterized by BI 90 (65-100), LB 4 (3-5), and CDR 1 (0-2), ICC 7.5 (6-10). 58% had FS ≥ 3. In the long term, they were in a situation of dependency [BI 50 (2.5-77.5), LB 3 (0-4), CDR 1 (0-1.5)]. The ICU mortality at 28 days and 6 months was 18.4%, 25.7% and 35.3%, respectively, being statistically significant. The area under the ISAR score ROC curve was 0.749 to 0.797, in all the mortality periods studied, although the difference with other predictive variables was not significant, but the p value was the lowest. CONCLUSIONS: The ISAR score predicts mortality in critically elderly patients with a discriminative capacity comparable to other predictive variables.

BACKGROUND: The number of intensive care patients aged ≥ 80 years (Very old Intensive Care Patients; VIPs) is growing. VIPs have high mortality and morbidity and the benefits of ICU admission are frequently questioned. Sepsis incidence has risen in recent years and identification of outcomes is of considerable public importance. We aimed to determine whether VIPs admitted for sepsis had different outcomes than those admitted for other acute reasons and identify potential prognostic factors for 30-day survival. RESULTS: This prospective study included VIPs with Sequential Organ Failure Assessment (SOFA) scores ≥ 2 acutely admitted to 307 ICUs in 21 European countries. Of 3869 acutely admitted VIPs, 493 (12.7%) [53.8% male, median age 83 (81-86) years] were admitted for sepsis. Sepsis was defined according to clinical criteria; suspected or demonstrated focus of infection and SOFA score ≥ 2 points. Compared to VIPs admitted for other acute reasons, VIPs admitted for sepsis were younger, had a higher SOFA score (9 vs. 7, p < 0.0001), required more vasoactive drugs [82.2% vs. 55.1%, p < 0.0001] and renal replacement therapies [17.4% vs. 9.9%; p < 0.0001], and had more life-sustaining treatment limitations [37.3% vs. 32.1%; p = 0.02]. Frailty was similar in both groups. Unadjusted 30-day survival was not significantly different between the two groups. After adjustment for age, gender, frailty, and SOFA score, sepsis had no impact on 30-day survival [HR 0.99 (95% CI 0.86-1.15), p = 0.917]. Inverse-probability weight (IPW)-adjusted survival curves for the first 30 days after ICU admission were similar for acute septic and non-septic patients [HR: 1.00 (95% CI 0.87-1.17), p = 0.95]. A matched-pair analysis in which patients with sepsis were matched with two control patients of the same gender with the same age, SOFA score, and level of frailty was also performed. A Cox proportional hazard regression model stratified on the matched pairs showed that 30-day survival was similar in both groups [57.2% (95% CI 52.7-60.7) vs. 57.1% (95% CI 53.7-60.1), p = 0.85]. CONCLUSIONS: After adjusting for organ dysfunction, sepsis at admission was not independently associated with decreased 30-day survival in this multinational study of 3869 VIPs. Age, frailty, and SOFA score were independently associated with survival.

ABSTRACT
BACKGROUND: Age has been traditionally considered a risk factor for mortality in elderly patients admitted to intensive care units. The aim of this prospective, observational, multicenter cohort study is to determine the risk factors for mortality in elderly and very elderly critically ill patients with sepsis. RESULTS: A total of 1490 patients with ≥ 65 years of age were included in the study; most of them 1231 (82.6%) had a cardiovascular failure. The mean age (± SD) was 74.5 (± 5.6) years, and 876 (58.8%) were male. The patients were divided into two cohorts: (1) elderly: 65-79 years and (2) very elderly: ≥ 80 years. The overall hospital mortality was 48.8% (n = 727) and was significantly higher in very elderly compared to elderly patients (54.2% vs. 47.4%; p = 0.02). Factors independently associated with mortality were APACHE II score of the disease, patient location at sepsis diagnosis, development of acute kidney injury, and thrombocytopenia in the group of elderly patients. On the other hand, in the group of very elderly patients, predictors of hospital mortality were age, APACHE II score, and prompt adherence of the resuscitation bundle. CONCLUSION: This prospective multicenter study found that patients aged 80 or over had higher hospital mortality compared to patients between 65 and 79 years. Age was found to be an independent risk factor only in the very elderly group, and prompt therapy provided within the first 6 h of resuscitation was associated with a reduction in hospital mortality in the very elderly patients.
ABSTRACT
BACKGROUND: Plasma concentrations of endocan, a proteoglycan preferentially expressed in the pulmonary vasculature, may represent a biomarker of lung (dys)function. We sought to determine whether the measurement of plasma endocan levels early in the course of acute respiratory distress syndrome (ARDS) could help predict risk of death or of prolonged ventilation. METHODS: All patients present in the department of intensive care during a 150-day period were screened for ARDS (using the Berlin definition). Endocan concentrations were measured at the moment of ARDS diagnosis (T0) and the following morning (T1). We compared data from survivors and non-survivors and data from survivors with less than 10 days of ventilator support (good evolution) and those who died or needed more than 10 days of mechanical ventilation (poor evolution). Results are presented as numbers (percentages), mean ± standard deviation or medians (percentile 25-75). RESULTS: Ninety-six consecutive patients were included [median APACHE II score of 21 (17-27) and SOFA score of 9 (6-12), PaO2/FiO2 ratio 155 (113-206)]; 64 (67%) had sepsis and 51 (53%) were receiving norepinephrine. Non-survivors were older (66 ± 15 vs. 59 ± 18 years, p = 0.045) and had higher APACHE II scores [27 (22-30) vs. 20 (15-24), p < 0.001] and blood lactate concentrations at study inclusion [2.1 (1.3-4.0) vs. 1.5 (0.9-2.6) mmol/L, p = 0.024] than survivors, but PaO2/FiO2 ratios [150 (116-207) vs. 158 (110-206), p = 0.95] were similar in the two groups. Endocan concentrations on the day after ARDS diagnosis were significantly higher in patients with poor evolution than in those with good evolution [12.0 (6.8-18.6) vs. 7.2 (5.4-12.5), p < 0.01]. CONCLUSION: Blood endocan concentrations early in the evolution of ARDS may be a useful marker of disease severity.
ABSTRACT
BACKGROUND: Acute respiratory distress syndrome (ARDS) is associated with vascular endothelial dysfunction. The resultant microvascular reactivity can be assessed non-invasively using near-infrared spectroscopy (NIRS) and a vascular occlusion test (VOT) and changes have been correlated with severity of organ dysfunction and mortality in other critically ill populations. We used NIRS to study the presence of microcirculatory alterations in patients with ARDS. METHODS: We studied 27 healthy volunteers and 32 ARDS patients admitted to our intensive care department. NIRS measurements were performed within 24 h after diagnosis (Berlin definition). VOTs were performed by inflating an arm-cuff to a pressure greater than the systolic pressure for 3 min, followed by rapid deflation. The descending (Desc) and ascending (Asc) thenar muscle oxygen saturation (StO2) slopes were calculated. We compared data from volunteers with those from ARDS patients, from ARDS survivors and non-survivors, and from ARDS survivors who required <7 days ventilatory support (good evolution) with those who required >7 days support or died (poor evolution). RESULTS: ARDS patients had lower StO2 values [75(67-80) vs 79(76-81) %, p = 0.04] and Asc slopes [185(115-233) vs 258(216-306) %/min, p < 0.01] than healthy volunteers, but Desc slopes were similar. The Asc slope was lower in the patients with a poor evolution than in the other patients [121(90-209) vs 222(170-293) %/min, p < 0.01], and in the non-survivors than in the survivors [95(73-120) vs 212(165-252) %/min, p < 0.01]. CONCLUSIONS: In ARDS patients, microvascular reactivity is altered early, and the changes are directly related to the severity of the disease. The ascending slope is the best determinant of outcome.
