Objective(s) : Since there is increasing evidence of serious deterioration in long-term Quality of Life (QoL) in COVID-19 intensive care unit (ICU) survivors, we identified predictors of poor quality of life in these patients. Design : Prospective cohort study. Setting : Research hospital repurposed in to a COVID-19 center. Participants : Consecutive patients admitted in COVID-19 ICU between March and June 2020. Interventions : A SF-36 questionnaire, which includes physical and mental items, was used 6 months after patients discharge. Measurements and Main Results : 403 patients were managed in the ICU with a hospital mortality of 181/403 (44.9%) while 16 (4.0%) further patients died within 6 months. Among the 125 questionnaire responders, only 32.0% and 52% had a normal quality of life in terms of the physical and mental component of health. Multivariable analysis identified low-molecular-weight heparin treatment in ICU as the only modifiable factor associated with an increase in physical component of QoL OR: 3.341 (95%CI 1.298-8.599), p=0.012, while age ≥52 years OR 0.223 and female sex OR 0.321 were significantly associated with a decrease in the physical component. Medical history of cerebrovascular insufficiency was significantly associated with a decrease in mental component of QoL OR: 0.125, while the only factor associated with an increase in the mental health component was BMI ≥ 27.6 kg / m2 OR 7.466. Conclusions : In COVID-19 intensive care unit survivors we identified treatment with low molecular weight heparin as a predictor of improved physical component of QoL at 6-months.
Septic shock, as the most severe form of sepsis, is characterized by high mortality reaching 40% despite the use of the most modern standards of diagnosis and treatment. In the thanatogenesis of septic shock, vasoplegia plays a leading role, respectively, and therapy of the condition under discussion involves the use of vasoconstrictors, along with the standard prescription of infusion therapy, antibiotics and symptomatic treatment. The choice of a specific vasoactive drug is a difficult task for a practicing anesthetist, as along with undoubtedly positive properties, vasoconstrictors each have their own spectrum of undesirable side effects, which, of course, must be taken into account when determining treatment tactics.The aim of review: A comprehensive assessment of the multifactorial effect of various vasoconstrictors on the patient to determine the criteria for choosing the optimal drug (or a combination of drugs) in septic shock.The search was carried out using PubMed and Scopus databases, the final selection of 89 articles was carried out in accordance with the following criteria: relevance to the topic of this review and the nature of the article — only randomized controlled trials, guidelines and analytical reviews were included in the final analysis.External and internal mechanisms of vascular tone regulation are considered, including factors produced by endothelium (nitric oxide, prostacyclin, endothelin); vasoactive metabolites and autocoids — signal molecules of local action (serotonin, prostaglandins, thromboxane A2). Accordingly, drugs were analyzed the mechanism of action of which is related to the effect on adrenergic (adrenaline, dopamine, norepinephrine, phenylephrine, dobutamine), vasopressin (vasopressin, terlipressin, selepressin) receptors, synthetic analogues of angiotensin (angiotensin II) and drugs the non-vasopressor effect of which is not linked with the receptor apparatus (methylene blue, levosimendan, hydrocortisone).Conclusion. The high effectiveness of norepinephrine, its positive hemodynamic effects make the drug under discussion, in many ways, a universal remedy for the relief of septic shock. However, refractory shock may require the introduction of such high doses of norepinephrine that the occurrence of adverse reactions will become practically inevitable. The combined use of adrenergic and ligand V receptors, terlipressin, is intended to prevent these complications. However, to date, there are no clear recommendations on the use of terlipressin in septic shock, which limits its use in clinical practice.

Aim of the study was to evaluate the feasibility of using a modified nomogram (the M nomogram) to predict the occurrence of new postoperative hemodynamically significant arrhythmias after elective cardiac surgery with cardiopulmonary bypass within 30 days post operation.Materials and methods. This was a retrospective cohort study. The prognostic value of the model using ROC-analysis of the modified nomogram was estimated based on the medical records of 144 patients who underwent elective cardiac surgery with cardiopulmonary bypass.Results. The incidence of new postoperative hemodynamically significant arrhythmias was 13.9% (20 of 144 patients). For the modified nomogram, the AUC was 0.777 [95% CI: 0.661–0.892] (P<0.001); at a cutoff of 12 points, the sensitivity was 60.0% and specificity was 89.52%. The odds ratio was 10.26 (95% CI: 3.63–29.06) (P<0.001). Conclusion. The modified nomogram has an acceptable prognostic value for the occurrence of new hemodynamically significant arrhythmias after elective cardiac operations with cardiopulmonary bypass based on AUC 0.777 [0.661–0.892] (P<0.001), and is currently the best model for predicting the outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
