Introduction: The use of invasive mechanical ventilation (IMV) in COVID-19 represents in an incremental burden to healthcare systems.
Aim of the study: We aimed to characterize patients hospitalized for COVID-19 who received IMV and identify risk factors for mortality in this population.
Material and Methods: A retrospective cohort study including consecutive adult patients admitted to a private network in Brazil who received IMV from March to October, 2020. A bidirectional stepwise logistic regression analysis was used to determine the risk factors for mortality.
Results: We included 215 patients, of which 96 died and 119 were discharged from ICU. The mean age was 62.7 ± 15.4 years and the most important comorbidities were hypertension (62.8%), obesity (50.7%) and diabetes (40%). Non-survivors had lower body mass index (BMI) (28.3 [25.5; 31.6] vs. 31.2 [28.3; 35], p<0.001, and a shorter duration from symptom onset to intubation (8.5 [6.0; 12] days vs. 10 [8.0; 12.5] days, p = 0.005). Multivariable regression analysis showed that the risk factors for mortality were age (OR: 1.07, 95% CI: 1.03 to 1.1, p < 0.001), creatinine level at the intubation date (OR: 3.28, 95% CI: 1.47 to 7.33, p = 0.004), BMI (OR: 0.91, 95% CI: 0.84 to 0.99, p = 0.033), lowest PF ratio within 48 hours post-intubation (OR: 0.988, 95% CI: 0.979 to 0.997, p = 0.011), barotrauma (OR: 5.18, 95% CI: 1.14 to 23.65, p = 0.034) and duration from symptom onset to intubation (OR: 0.76, 95% CI: 0.76 to 0.95, p = 0.006).
Conclusion: In our retrospective cohort we identified the main risk factors for mortality in COVID-19 patients receiving IMV: age, creatinine at the day of intubation, BMI, lowest PF ratio 48-hours post-intubation, barotrauma and duration from symptom onset to intubation.

Background: Increasing awareness of the emotional impact of an Intensive Care Unit (ICU) hospitalization on patients and their families has led to a rise in studies seeking to mitigate Post Intensive Care Syndrome (PICS) for both groups. In efforts to decrease symptoms of anxiety and depression, ICUs have implemented a variety of programs to reduce family distress.
Methods: We conducted a systematic review of experimental studies which aimed to reduce stress related disorders in family members after the experience of having a patient admitted to the ICU. Multiple databases were searched for randomized controlled trials or nonrandomized comparative trials which targeted family members or surrogate decision makers. A total of 17 studies were identified for inclusion in the review representing 3471 participants.
Results: We describe those interventions which we qualitatively assigned as “not passive,” or those which actively engaged the family to express themselves, as more likely to be successful in both the available pediatric and adult literature than interventions which we identified as “passive.” Studies which described active engagement of family members demonstrated comparative improvements in symptoms of depression, anxiety, and PTSD, as well as reduced hospital costs in the case of two studies.
Discussion: This review may serve to aid in the development of future interventions targeted at reducing family stress and PICS following an ICU hospitalization.

Aim: The aim of this study was to evaluate whether systemic immune-inflammation index (SII) could predict mortality in patients with novel coronavirus 2019 (COVID-19) disease.
Methods: This two-center, retrospective study included a total of 191 patients with confirmed diagnosis of COVID-19 via nucleic acid test (NAT). The SII was calculated based on the complete blood parameters (neutrophil × platelet/lymphocyte) during hospitalization. The relationship between the SII and other inflammatory markers and mortality was investigated.
Results: The mortality rate was 18.3%. The mean age was 54.32±17.95 years. The most common symptoms were fever (70.7%) and dry cough (61.3%), while 8 patients (4.2%) were asymptomatic. The most common comorbidities were hypertension (37.7%), diabetes (23.0%), chronic renal failure (14.7%), and heart failure (7.9%) which all significantly increased the mortality rate (p<0.001). There was a highly positive correlation between the SII and polymorphonuclear leukocyte (PNL), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) (r=0.754, p<0.001; r=0.812, p<0.001; r=0.841, p<0.001, respectively), while a moderate, positive correlation was found between the SII and C-reactive protein (CRP) (r=0.439, p<0.001). There was a significant correlation between the SII and mortality (U=1,357, p<0.001). The cut-off value of SII was 618.8 (area under the curve=0.751, p<0.001) with 80.0% sensitivity and 61.5% specificity. A cut-off value of >618.8 was associated with a 4.68-fold higher mortality.
Conclusion: Similar to NLR and PLR, the SII is a proinflammatory marker of systemic inflammation and can be effectively used in independent predicting COVID-19 mortality .

Introduction: Healthcare professionals, due to the nature of their work, have always experienced occupational stress, depression and low quality of life, which have been aggravated during the COVID-19 pandemic.
Aim: A large-scale cross-sectional descriptive correlational study aimed to investigate the impact of the COVID-19 pandemic on Greek healthcare professionals’ psychological status and quality of life.
Material and Methods: The study was conducted at “Attikon” General University Hospital and the 2nd Health Region in Athens, Greece. An assessment of anxiety and depression was carried out using the Zung’s Self-Rating Anxiety and Depression Scale (SAS/SDS). To assess the participants’ Quality of Life (QoL) the Short Form Survey-36 (SF-36) was used.
Results: 147 healthcare professionals were enrolled in the study. 70.7% experienced normal stress levels, 23.8% mild, 4.8% moderate and 0.7% severe. Mild depression was experienced by 34.7%, moderate by 10.2% and severe by 1.4%, with a 53.7% showing no depressive symptoms. Women experienced higher levels of anxiety and depression (p=0.001 & 0.001 respectively), and were 5.4 times more at risk to develop anxiety [Odds Ratio (OR) 5.357, 95% Confidence Interval (CI), 1.95-14.72: p=0.001] and 3.4 depression (OR, 3.365, 95% CI, 1.59- 7.12: p=0.002). Nurses and other professionals experienced higher stress and depression levels (p=0.004 & 0.040 respectively) than doctors. Participants reporting more exhaustion exhibited higher anxiety and depression levels (p=0.001). Compared to the pre-COVID-19 era, women (p=0.001), other health professionals (p=0.001) and those experiencing more physical burnout during COVID-19 (p=0.005) reported worse physical health. Anxiety and depression were negatively correlated with most sub scales of SF-36 except social functioning and bodily pain (p=0.001).
Conclusions: Healthcare professionals’ QoL has been affected by the COVID-19 pandemic and they experience higher levels of anxiety and depression. There is a need to develop strategies to address the negative psychological impact of this pandemic on healthcare professionals.

DOI: 10.2478/jccm-2022-0008

Introduction: Hyperbaricoxygen therapy (HBOT) is breathing100% oxygen in pressurised chamber. This therapy ensures quick oxygen delivery to the bloodstream. In patients with severe COVID-19 pneumonia, progressive hypoxemia occurs. Oxygen therapy hasa significant role in its management.
Aim of the study: The objective was to study the efficacy of hyperbaric oxygen therapy (HBOT) as adjuvant therapy for reducing the requirement of additional oxygen supplementationin patients with moderate to severe ARDS diagnosed with COVID-19.
Methods: A single-centre prospective pilot cohort study was conducted ata tertiary care hospital from December 2020 to February 2021 over two months. Fifty patients with COVID-19 needingoxygen, satisfying the selection criteria, were included. Hyperbaricoxygen therapy wasgiven to all patients. The patient received30-45 minutes of hyperbaric oxygen with 15 minutes of pressurizing and depressurizing at 2.0 atmosphere absolute (ATA) with or without airbrakesas per the critical care team. Oxygen requirement, PaO2, andcondition at discharge were considered as primary outcome variables.
Results: Among the 50 participants studied, the mean age was 53.64±13.26 years. Out of 50 participants, 49(98.00%) had PaO2≤80 mmHg, and one (2.00%) had >80 PaO2. All the participants 50(100%) had PaO2 as 90 mmHg after three sittings.
Conclusion: This studyshows promising results in using HBOT to overcome respiratory failure in COVID-19. HBOT reduced the need for oxygen by improving the oxygen saturation levels.

Community hospitals will often transfer their most complex, critically ill patients to intensive care units (ICUs) of tertiary care centers for specialized, comprehensive care. This population of patients has high rates of morbidity and mortality. Palliative care involvement in critically ill patients has been demonstrated to reduce over-utilization of resources and hospital length of stays. We hypothesized that transfers from community hospitals had low rates of palliative care involvement and high utilization of ICU resources. In this single-center retrospective cohort study, 848 patients transferred from local community hospitals to the medical ICU (MICU) and cardiac care unit (CCU) at a tertiary care center between 2016-2018 were analyzed for patient disposition, length of stay, hospitalization cost, and time to palliative care consultation. Of the 848 patients, 484 (57.1%) expired, with 117 (13.8%) having expired within 48 hours of transfer. Palliative care consult was placed for 201 (23.7%) patients. Patients with palliative care consult were statistically more likely to be referred to hospice (p<0.001). Over two-thirds of palliative care consults were placed later than 5 days after transfer. Time to palliative care consult was positively correlated with length of hospitalization among MICU patients (r=0.79) and CCU patients (r=0.90). Time to palliative consult was also positively correlated with hospitalization cost among MICU patients (r=0.75) and CCU patients (r=0.86). These results indicate early palliative care consultation in this population may result in timely goals of care discussions and optimization of resources.

Background: Renal involvement in COVID-19 leads to severe disease and higher mortality. We study renal parameters in COVID-19 patients and their association with mortality and length of stay in hospital. Methods: A retrospective study (n=340) of confirmed COVID-19 patients with renal involvement determined by the presence of acute kidney injury. Multivariate analyses of logistic regression for mortality and linear regression for length of stay (LOS) adjusted for relevant demographic, comorbidity, disease severity, and treatment covariates. Results: Mortality was 54.4% and mean LOS was 12.9 days. For mortality, creatinine peak (OR:35.27, 95% CI:2.81, 442.06, p<0.01) and persistent renal involvement at discharge (OR:4.47, 95% CI:1.99,10.06, p<0.001) were each significantly associated with increased odds for mortality. Increased blood urea nitrogen peak (OR:0.98, 95%CI:0.97,0.996, p<0.05) was significantly associated with decreased odds for mortality. For LOS, increased blood urea nitrogen peak (B:0.001, SE:<0.001, p<0.01), renal replacement therapy (B:0.19, SE:0.06, p<0.01), and increased days to acute kidney injury (B:0.19, SE:0.05, p<0.001) were each significantly associated with increased length of stay. Conclusion: Our study emphasizes the importance in identifying renal involvement parameters in COVID-19 patients. These parameters are associated with LOS and mortality, and may assist clinicians to prognosticate COVID-19 patients with renal involvement.

Dubito ergo sum. Pathologies that can mimic sepsis

Bianca-Liana Grigorescu

Department of Pathophysiology, George Emil Palade University of Medicine, Pharmacy, Science, and Technology of Targu-Mures, Romania

DOI: 10.2478/jccm-2022-0011

Sepsis is a potentially deadly organ dysfunction caused by a dysregulated host response to infection, with a high mortality rate [1]. Generally, sepsis is acquired in the community, and its development is slow, making diagnosis challenging. Early broad-spectrum antibiotics and effective source management improve prognosis [1, 2].
Sepsis has a huge financial impact on the health-care system; septic patient treatment in the United States alone is projected to cost more than $20 billion per year. The cost in human life is equally high; mortality rates in sepsis and septic shock are believed to be more than 10% and 40%, respectively [3]. Sepsis is one of the most prevalent causes for admission to the intensive care unit (ICU) and the leading cause of mortality in ICUs across the globe [3, 4]. [More]

Introduction: Noonan syndrome (NS) is a dominant autosomal disease, caused by mutations in genes involved in cell differentiation, growth and senescence, one of them being RAF1 mutation. Congenital heart disease may influence the prognosis of the disease.
Case presentation: We report a case of an 18 month-old female patient who presented to our institute at the age of 2 months when she was diagnosed with obstructive hypertrophic cardiomyopathy, pulmonary infundibular and pulmonary valve stenosis, a small atrial septal defect and extrasystolic arrhythmia. She was born from healthy parents, a non-consanguineous marriage. Due to suggestive phenotype for NS molecular genetic testing for RASopathies was performed in a center abroad, establishing the presence of RAF-1 mutation. Following rapid progression of cardiac abnormalities, the surgical correction was performed at 14 months of age. In the early postoperative period, the patient developed episodes of sustained ventricular tachycardia with hemodynamic instability, for which associated treatment was instituted with successful conversion to sinus rhythm. At 3-month follow-up, the patient was hemodynamically stable in sinus rhythm.
Conclusions: The presented case report certifies the importance of recognizing the genetic mutation in patients with NS, which allows predicting the severity of cardiac abnormalities and therefore establishing a proper therapeutic management of these patients.
