Características,evolución clínica y factores asociados a la mortalidad en UCI de los pacientes críticos infectados por SARS-CoV-2 en España: estudio prospectivo,de cohorte y multicéntrico

BackgroundThe clinical course of COVID-19 critically ill patients, during their admission in the intensive care unit (UCI), including medical and infectious complications and support therapies, as well as their association with in-ICU mortality has not been fully reported.ObjectiveThis study aimed to describe clinical characteristics and clinical course of ICU COVID-19 patients, and to determine risk factors for ICU mortality of COVID-19 patients.MethodsProspective, multicentre, cohort study that enrolled critically ill COVID-19 patients admitted into 30 ICUs from Spain and Andorra. Consecutive patients from March 12^th to May 26^th, 2020 were enrolled if they had died or were discharged from ICU during the study period. Demographics, symptoms, vital signs, laboratory markers, supportive therapies, pharmacological treatments, medical and infectious complications were reported and compared between deceased and discharged patients.ResultsA total of 663 patients were included. Overall ICU mortality was 31% (203 patients). At ICU admission non-survivors were more hypoxemic [SpO₂ with non-rebreather mask, 90 (IQR 83 to 93) vs. 91 (IQR 87 to 94); P<.001] and with higher sequential organ failure assessment score [SOFA, 7 (IQR 5 to 9) vs. 4 (IQR 3 to 7); P<.001]. Complications were more frequent in non-survivors: acute respiratory distress syndrome (ARDS) (95% vs. 89%; P=.009), acute kidney injury (AKI) (58% vs. 24%; P<10^-16), shock (42% vs. 14%; P<10^-13), and arrhythmias (24% vs. 11%; P<10^-4). Respiratory super-infection, bloodstream infection and septic shock were higher in non-survivors (33% vs. 25%; P=.03, 33% vs. 23%; P=.01 and 15% vs. 3%, P=10^-7), respectively. The multivariable regression model showed that age was associated with mortality, with every year increasing risk-of-death by 1% (95%CI: 1 to 10, P=.014). Each 5-point increase in APACHE II independently predicted mortality [OR: 1.508 (1.081, 2.104), P=.015]. Patients with AKI [OR: 2.468 (1.628, 3.741), P<10^-4)], cardiac arrest [OR: 11.099 (3.389, 36.353), P=.0001], and septic shock [OR: 3.224 (1.486, 6.994), P=.002] had an increased risk-of-death.ConclusionsOlder COVID-19 patients with higher APACHE II scores on admission, those who developed AKI grades ii or iii and/or septic shock during ICU stay had an increased risk-of-death. ICU mortality was 31%.

Incidence,features, outcome and impact on health system of de-novo abdominal surgical diseases in patients admitted with COVID-19

Objectiveto assess the epidemiology and features of de novo surgical diseases in patients admitted with COVID-19, and their impact on patients and healthcare system.Summary background dataGastrointestinal involvement has been described in COVID-19; however, no clear figures of incidence, epidemiology and economic impact exist for de-novo surgical diseases in hospitalized patients.MethodsThis is a prospective study including all patients admitted with confirmed SARS-CoV-2 rT-PCR, between 1 March and 15 May 2020 at two Tertiary Hospitals. Patients with known surgical disease at admission were excluded. Sub-analyses were performed with a consecutive group of COVID-19 patients admitted during the study period, who did not require surgical consultation.ResultsTen out of 3089 COVID-19 positive patients (0.32%) required surgical consultation. Among those admitted in intensive care unit (ICU) incidence was 1.9%. Mortality was 40% in patients requiring immediate surgery and 20% in those suitable for conservative management. The overall median length of stay (LOS) of patients admitted to ICU was longer in those requiring surgical consultation compared with those who did not (51.5 vs 25 days, p = 0.0042). Patients requiring surgical consultation and treatment for de-novo surgical disease had longer median ICU-LOS (31.5 vs 12 days, p = 0.0004). A median of two post-surgical complications were registered for each patient undergoing surgery. Complication-associated costs were as high as 38,962 USD per patient.ConclusionsIncidence of de-novo surgical diseases is low in COVID-19, but it is associated with significant morbidity and mortality. Future studies should elucidate the mechanism underlying the condition and identify strategies to prevent the need for surgery.     

Decreased Incidence of Hirschsprung-Associated Enterocolitis During COVID-19 Across United States Children's Hospitals

BackgroundThe Coronavirus Disease 2019 pandemic provided a natural experiment to study the effect of social distancing on the risk of developing Hirschsprung's Associated Enterocolitis (HAEC).MethodsUsing the Pediatric Health Information System (PHIS), a retrospective cohort study of children (<18 years) with Hirschsprung's Disease (HSCR) across 47 United States children's hospitals was performed. The primary outcome was HAEC admissions per 10,000 patient-days. The exposure (COVID-19) was defined as April 2020–December 2021. The unexposed (historical control) period was April 2018–December 2019. Secondary outcomes included sepsis, bowel perforation, intensive care unit (ICU) admission, mortality, and length of stay.ResultsOverall, we included 5707 patients with HSCR during the study period. There were 984 and 834 HAEC admissions during the pre-pandemic and pandemic periods, respectively (2.6 vs. 1.9 HAEC admissions per 10,000 patient-days, incident rate ratio [95% confidence interval]: 0.74 [0.67, 0.81], p < 0.001). Compared to pre-pandemic, those with HAEC during the pandemic were younger (median [IQR]: 566 [162, 1430] days pandemic vs. 746 [259, 1609] days pre-pandemic, p < 0.001) and more likely to live in the lowest quartile of median household income zip codes (24% pandemic vs. 19% pre-pandemic, p = 0.02). There were no significant differences in rates of sepsis (6.1% pandemic vs. 6.1% pre-pandemic, p > 0.9), bowel perforation (1.3% pandemic vs. 1.2% pre-pandemic, p = 0.8), ICU admissions (9.6% pandemic vs. 12% pre-pandemic, p = 0.2), mortality (0.5% pandemic vs. 0.6% pre-pandemic, p = 0.8), or length of stay (median [interquartile range]: 4 [(Pastor et al., 2009; Gosain and Brinkman, 2015) 2,112,11 days pandemic vs. 5 [(Pastor et al., 2009; Tang et al., 2020) 2,102,10 days pre-pandemic, p = 0.4).ConclusionsThe COVID-19 pandemic was associated with significantly decreased incidence of HAEC admissions across US children's hospitals. Possible etiologies such as social distancing should be explored.Level of evidenceII.     

Calidad de vida y síntomas persistentes tras hospitalización por COVID-19. Estudio observacional prospectivo comparando pacientes con o sin ingreso en UCI

BackgroundHospitalized COVID-19 patients are prone to develop persistent symptoms and to show reduced quality of life following hospital admission.MethodsProspective cohort study of COVID-19 patients admitted to a hospital from March 1 to April 30, 2020. The primary outcome was to compare health related quality of life and persistent symptoms six months after hospital admission, of COVID-19 patients who required ICU admission with those who did not.ResultsAmong the 242 patients hospitalized during the defined period of time, 44 (18.2%) needed ICU admission. Forty (16.5%) patients died during hospital admission. Two hundred and two (83.5%) patients were discharged alive from the hospital. At six months, 183 (75.6%) patients completed the questionnaires (32 ICU patients and 151 non ICU patients). Ninety-six (52.4%) reported decreased quality of life and 143 (78.1%) described persistent symptoms. More ICU patients showed worsening of their quality of life (71.9 vs. 43.7%, P = 0.004). There were no differences in the proportion of patients with persistent symptoms between ICU and non ICU patients (87.5 vs. 76.2%, P = 0.159). ICU patients showed more frequently dyspnea on exertion (78.1 vs. 47.7%, P = 0.02), dyspnea on light exertion (37.5 vs. 4.6%, P < 0.001), and asthenia (56.3 vs. 29.1, P = 0.003).ConclusionsSurvivors of COVID-19 needing hospitalization had persistent symptoms and a decline in the quality of life. ICU patients referred a large decrease of their quality of life compared with non ICU patients.     

Impact of COVID-19 Pandemic on Organ Donation in Hong Kong: A Single-Center Observational Study

IntroductionThe coronavirus disease 2019 (COVID-19) pandemic was expected to have a negative impact on organ donation. With the differences in health care systems and lockdown policies in various regions, the pandemic's effect on organ donation and transplant service may vary. Most of the deceased donor organ referrals in our hospital came from non–intensive care units (ICUs). The objective of this study is to report our experience and quantify the effects of the COVID-19 pandemic on deceased donor organ donation in our center.MethodsThis was a retrospective observational study comparing the deceased donor organ donation activity during the period January 23 to November 30, 2020 with the same period in 2018 in Queen Elizabeth Hospital, Hong Kong.ResultsThere was a 26.9% reduction in deceased donor organ donor referral in 2020 compared with 2018. No significant difference in the proportion of referrals from ICU or non-ICU areas between the 2 time periods was observed. The brain death confirmation rate was significantly higher in 2020 (40.8% vs 20.2%, P = .003). Nine patients had family consent for organ donation in 2020 (vs 7 patients in the same period in 2018). There were no significant differences in consent rate and number of recovered organs between the 2 periods.ConclusionsWith effective measures to limit the spread of COVID-19 in a community, it is possible to support the needs of both patients with COVID-19 and deceased donor organ donation services.     

Rare and Unusual Follow-up Sequelae of Coronavirus Disease 2019: Splenic Mucormycosis in a Renal Transplant Recipient

BackgroundCoronavirus disease 2019 (COVID-19) is associated with adverse outcomes in transplantation communities. Mucormycosis, although a rare infection, has been classically linked to organ transplantation and is associated with exceptionally high morbidity and mortality rates. In this pandemic era, the double infection of mucormycosis and COVID-19 is a lethal combination but is rarely described in the literature on organ transplantation.Case presentationThis article presents the case of a young kidney transplant recipient with diabetes who acquired severe COVID-19, followed by disseminated mucormycosis. The patient was a health care worker who developed severe COVID-19, for which he received remdesivir, anticoagulation, and dexamethasone. No immunomodulatory therapy was used. His maximum oxygen support was bilevel positive airway pressure ventilation. His sugar levels were frequently deranged during the stay. He developed secondary sepsis with Klebsiella, followed by nonhealing lung consolidation. He later developed pleural effusion and splenic abscess, which was detected incidentally. He underwent an emergency splenectomy, the culture of which yielded mucormycosis. Liposomal amphotericin B 5 mg/kg was administered. The patient deteriorated, and a repeat laparotomy yielded gastric perforation, with pus culture showing mucormycosis. The patient died after a long hospital stay.ConclusionsThe diagnosis and management of this dual infection during the pandemic is extremely challenging. In this case, the unusual location of mucormycosis complicating COVID-19 calls for a meticulous approach to opportunistic fungal infections in organ transplant recipients who are positive for COVID-19, especially in those patients with diabetes.     

Postoperative sepsis and septic shock after hip fracture surgery

IntroductionThere is a paucity of research in the rates for sepsis and septic shock in the hip fracture population specifically, despite marked clinical and prognostic differences between these conditions. The purpose of this study was to determine the incidence, risk factors, and mortality rates for sepsis and septic shock as well as evaluate potential infectious causes in the surgical hip fracture population.MethodsThe ACS-NSQIP (2015–2019) was queried for patients who underwent hip fracture surgery. A backward elimination multivariate regression model was used to identify risk factors for sepsis and septic shock. Multivariate regression that controlled for preoperative variables and comorbidities was used to calculate the odds of 30-day mortality.ResultsOf 86,438 patients included, 871 (1.0%) developed sepsis and 490 (0.6%) developed septic shock. Risk factors for both postoperative sepsis and septic shock were male gender, DM, COPD, dependent functional status, ASA class ≥3, anemia, and hypoalbuminemia. Unique risk factors for septic shock were CHF and ventilator dependence. The 30-day mortality rate was 4.8% in aseptic patients, 16.2% in patients with sepsis, and 40.8% in patients who developed septic shock (p < 0.001). Patients with sepsis (OR 2.87 [95% CI 2.37–3.48], p < 0.001) and septic shock (OR 11.27 [95% CI 9.26–13.72], p < 0.001) had increased odds of 30-day mortality compared to patients without postoperative septicemia. Infections that preceded a diagnosis of sepsis or septic shock included urinary tract infections (24.7%, 16.5%), pneumonia (17.6%, 30.8%), and surgical site infections (8.5%, 4.1%).ConclusionsThe incidence of sepsis and septic shock after hip fracture surgery was 1.0% and 0.6%, respectively. The 30-day mortality rate was 16.2% in patients with sepsis and 40.8% in patients with septic shock. Potentially modifiable risk factors for both sepsis and septic shock were anemia and hypoalbuminemia. Urinary tract infections, pneumonia, and surgical site infections preceded the majority of cases of sepsis and septic shock. Prevention, early identification, and successful treatment of sepsis and septic shock are paramount to lowering mortality after hip fracture surgery.     

COVID-19 patients with obesity at risk for worse outcomes despite younger age and fewer inflammatory derangements

BackgroundCoronavirus disease 2019 (COVID-19) is a viral pulmonary infection that can progress to cytokine storm syndrome because of widespread dysregulated inflammatory response. Many patients at risk for severe COVID-19 manifestation have been identified as those with preexisting conditions of pulmonary origin, as well as conditions that impair appropriate immune response, such as obesity.ObjectivesThe aim of this study is to describe the manifestation, clinical course, and inflammatory biomarker milieu of COVID-19 in patients with obesity.SettingUniversity Hospital Philadelphia, Pennsylvania.MethodsIn this retrospective cohort study, 600 patients who were positive for COVID-19 were stratified by World Health Organization (WHO) obesity class and their presenting symptoms, disease biomarkers, demographics, and outcomes (intubation rate, intensive care unit [ICU] admission, length of stay [LOS], and mortality) were investigated.ResultsAge was inversely related to obesity class; patients of obesity class III presented 12.9 years younger than patients of normal weight (P < .0001). Initial ferritin lab values were negatively correlated with increasing obesity class (P = .0192). Normal or near-normal lymphocyte profile was noted in patients with obesity compared with patients without obesity (P = .0017). Patients with obesity had an increased rate of ICU admission (P = .0215) and increased length of stay (P = .0004), but no differences in intubation rate (P = .3705) or mortality (P = .2486).ConclusionPatients with obesity were more likely to present to the hospital at a younger age, with reduced levels of COVID-19 related biomarker disturbances, and increased LOS and ICU admission rates, although were not at increased risk for mortality.     

Primary sepsis in a university hospital in northern Sweden: a retrospective study

BACKGROUND: Severe sepsis and septic shock are associated with high mortality rates. Data on sepsis outcome from Scandinavian countries are sparse. The aim of this study was to examine the length of stay (LOS) in the ICU, ICU mortality and costs of care for adult patients with primary sepsis in a university hospital in northern Sweden. METHODS: We performed a retrospective data analysis of records of 92 patients admitted over a 3-year period, under the diagnosis of sepsis or urosepsis. Demographic data, admission category, APACHE II score, aetiology and severity of sepsis, ICU LOS, mortality and TISS were analyzed. RESULTS: Eighty-one adult patients were identified by standard definitions as suffering from sepsis. The median ICU length of stay was 4.2 days, 6 days for survivors and 2.1 days for non-survivors. Thirteen out of 20 deaths occurred within the first 3 days after admission. Overall ICU mortality rate was 24.7% while the ICU mortality for patients with septic shock was 57.7%. The mean costs of care for patients with sepsis were 3139 Euros day(-1) and the cost of care per patient surviving sepsis was 38,494 Euros. CONCLUSION: The incidence of primary sepsis in our ICU was low. Previous reports on high mortality in association with severe sepsis and septic shock are valid also at our hospital. The ICU-LOS was shorter than previously reported, while our costs of care were in the same range as stated by others. This retrospective analysis is valid for interpretation of the applicability of currently available sepsis therapies.     

Comparing epidemiologic features,outcomes, and diagnostic and therapeutic procedures of traumatic patients before and during COVID-19 pandemic: Data from the National Trauma Registry of Iran

PurposeTo prepare for future possible communicable disease epidemics/pandemics, health care providers should know how the COVID-19 pandemic influenced injured patients. This study aimed to compare epidemiologic features, outcomes, and diagnostic and therapeutic procedures of trauma patients admitted to a university-affiliated hospital before and during the pandemic.MethodsThis retrospective study was performed on data from the National Trauma Registry of Iran. All injured patients admitted to the hospital from July 25, 2016 to March 10, 2021 were included in the study. The patients were excluded if they had hospital length of stay less than 24 h. The injury outcomes, trauma mechanisms, and therapeutic and diagnostic procedures of the 2 periods: before (from July 25, 2016 to February 18, 2020) and during (from February 19, 2020 to March 10, 2021) COVID-19 pandemic were compared. All analyses were performed using STATA version 14.0 software (Stata Corporation, College Station, TX).ResultsTotally, 5014 patients were included in the registry. Of them, 773 (15.4%) were registered after the beginning of the COVID-19 pandemic on February 19, 2020, while 4241 were registered before that. Gender, education level, and cause of injury were significantly different among the patients before and after the beginning of the pandemic (p < 0.001). In the ≤ 15 years and ≥ 65 years age groups, injuries decreased significantly during the COVID-19 pandemic (p < 0.001). The frequency of intensive care unit (ICU) admission decreased from 694 (16.4%) to 88 (11.4%) (p < 0.001). The mean length of stay at the hospital (days) and at the ICU (days) declined as follow: 8.3 (SD = 17.2) vs. 5.5 (SD = 6.1), p < 0.001 and 7.5 (SD = 11.5) vs. 4.5 (SD = 6.3), p < 0.022. The frequency of diagnostic and therapeutic procedures before and during the pandemic was as follows, respectively: ultrasonography 905 (21.3%) vs. 417 (53.9%) (p < 0.001), echocardiography 313 (7.4%) vs. 107 (13.8%) (p < 0.001), angiography 1597 (37.7%) vs. 534 (69.1%) (p < 0.001), MRI 166 (3.9%) vs. 51 (6.6%) (p < 0.001), surgery 3407 (80.3%) vs. 654 (84.6%) (p < 0.001), and internal/external fixation 1215 (28.6%) vs. 336 (43.5%) (p < 0.001).ConclusionThe pandemic affected the epidemiology of traumatic patients in terms of gender, age, educational level, and trauma mechanism. It changed the outcomes of injured patients: ICU admission, length of stay at the hospital and ICU decreased. The patients received more diagnostic and therapeutic procedures during the pandemic. To be more precise, more research is needed on the details.     

Sepsis is associated with lack of monocyte HLA-DR expression recovery without modulating T-cell reconstitution after lung transplantation

BackgroundImmunosuppressive strategy targets mainly adaptive immunity after solid organ transplantation. We assessed the influence of early post-operative sepsis on T cell and monocyte reconstitution in anti-thymocyte globulin (ATG)-treated lung transplant recipients.MethodsWe retrospectively included recipients who underwent a first lung transplant at our Lung Transplant Center (Marseille, France) between July 2011 and February 2013. Peripheral blood T-lymphocyte subset counts and monocyte HLA-DR (mHLA-DR) expression routinely performed by flow cytometry within 60 days post-transplant were analyzed. We compared the immune kinetics of patients who did or did not develop sepsis during the post-operative intensive care unit stay.ResultsAmong the 37 recipients included, 19 patients (51%) developed at least one episode of sepsis. At the ICU admission, septic recipients had higher SOFA score (9 [7.5–9] versus 6 [[4], [5], [6], [7]]), p = .01), higher primary graft dysfunction score (1.4 ± 1.4 versus 0.3 ± 0.7, p = .008) and more frequent use of ECMO (47% versus 0%, p = .003). Whereas both groups had similar T-lymphocytes reconstitution in the post-operative period, mHLA-DR reconstitution was dramatically affected in septic patients after day 14, median mHLA-DR expression at 2.3 MFI [1.3–3.5] in the septic versus 8.0 MFI [5.1–10.5] in the non-septic group, p = .02.ConclusionWe found that sepsis is negatively correlated with the mHLA-DR expression but not adaptive T cell immune reconstitution. This finding highlights the importance of immunomonitoring after lung transplantation and questions the strategy of a lower immunosuppression therapy in context of sepsis.     

Pacientes críticos COVID-19 atendidos por anestesiólogos en el Noroeste de España: estudio multicéntrico,prospectivo, observacional

Background and objectivesThere are limited information on outcome, complications and treatments of critically ill COVID-19 patients requiring admission to an intensive care unit (ICU). The aim of this study is to describe the clinical ICU course, treatments used, complications and outcomes, of critically ill COVID-19 patients admitted in seven ICU in Galicia region during the 2020 March-April pandemic peak.MethodsBetween March 21 and April 19, 2020, we evaluated critically ill COVID-19 patients admitted to the ICU of Anesthesia of seven hospitals in Galicia, northwestern Spain. Outcome, complications, and treatments were monitored until May 6, 2020, the final date of follow-up.ResultsA total of 97 critically ill COVID-19 patients were included. During ICU stay, mechanical ventilation became necessary in 80 (82.5%) patients, and tracheostomy in 22 (22.7%) patients. Prone position was used frequently in both intubated (67.5%) and awake (27.8%) patients. Medications consisted of antivirals agents (92.7%), corticosteroids (93.8%), tocilizumab (57.7%), and intermediate or high doses of anticoagulants (83.5%). The most frequent complications were ICU-acquired infection (52.6%), thrombosis events (16.5%), and reintubation (9.3%). After a median follow-up of 42 (34-45) days, 15 patients (15.5%) deceased, 73 patients (75.2%) had been discharged from ICU, and nine patients (9.3%) were still in the ICU.ConclusionsA high proportion of our critically ill COVID-19 patients required mechanical ventilation, prone positioning, antiviral medication, corticosteroids, and anticoagulants. ICU complications were frequent, mainly infections and thrombotic events. We had a relatively low mortality of 15,5%.     

Effect of the COVID-19 pandemic on bariatric surgery in North America: a retrospective analysis of 834,647 patients

BackgroundCOVID-19 has transformed surgical care, yet little is known regarding implications for bariatric surgery.ObjectiveWe sought to characterize the effect of COVID-19 on bariatric surgery delivery and outcomes.SettingThe Metabolic and Bariatric Accreditation and Quality Improvement Program (MBSAQIP) collects data from 885 centers in North America.MethodsThe MBSAQIP database was evaluated with 2 cohorts described: the COVID-19 and the pre–COVID-19, with patients receiving surgery in 2020 and 2015–2019, respectively. Yearly operative trends were characterized, and bivariate analysis compared demographics and postoperative outcomes. Multivariable modeling evaluated 30-day readmission, reintervention, and reoperation rates and factors associated with undergoing Roux-en-Y gastric bypass.ResultsWe evaluated 834,647 patients, with 155,830 undergoing bariatric surgery during the 2020 pandemic year. A 12.1% reduction in total cases (177,208 in 2019 versus 155,830 in 2020; P < .001) and 13.8% reduction in cases per center occurred (204.2 cases per center in 2019 versus 176.1 cases per center in 2020; P < .001). Patients receiving bariatric surgery during the pandemic were younger and had fewer co-morbidities. Use of sleeve gastrectomy increased (74.5% versus 72.5%; P < .001), and surgery during COVID-19 was associated with reduced Roux-en-Y gastric bypass procedure selection (odds ratio = .83; 95% CI: .82–.84; P < .001). Length of stay decreased significantly (1.4 ± 1.4 days versus 1.6 ± 1.4 days; P < .001), yet postoperative outcomes were similar. After adjusting for co-morbidities, patients during COVID-19 had decreased 30-day odds of readmission and reintervention and a small increase in odds of reoperation.ConclusionThe COVID-19 pandemic dramatically changed bariatric surgery delivery. Further studies evaluating the long-term effects of these changes are warranted.

Is Early COVID-19 in Kidney Transplant Recipients Concerning Enough to Halt Transplantation? A Multicenter Comparative Analysis from India

BackgroundLimited data exist on the incidence and outcome of early coronavirus disease 2019 (COVID-19) in kidney transplantation recipients (KTR).MethodsA retrospective multicenter research study was conducted across 12 centers in India. We explored the symptomatology, demographic, laboratory findings, and outcome of COVID-19 within 30 days of transplantation. The outcome was compared with the overall KTR and waitlisted patients acquiring COVID-19.ResultsThe incidence of early COVID-19 was 2.6% (n = 22) for the cumulative 838 renal transplants performed since nationwide lockdown in March 2020 until May 2021. Overall, 1049 KTR were diagnosed with COVID-19 and 2% of those had early COVID-19. The median age of the early COVID-19 cohort was 43 (31-46) years. COVID-19 severity ranged from asymptomatic (18.2%), mild (59.1%), moderate (9.1%), and severe (13.6%). Among clinical symptoms, dyspnea and anosmia were frequent, and in laboratory parameters, neutrophil lymphocyte ratio, high-sensitivity C-reactive protein, and D-dimer were higher in patients requiring oxygen. The mortality in early COVID-19 was not higher than overall KTR (4.5% vs 8.5%; P = 1). COVID-19 severity (23.9% vs 15.7%; P = .0001) and mortality (15.5% vs 8.5%; P = .001) among waitlisted patients (n = 1703) were higher compared with overall KTR.ConclusionsWe report higher burden of COVID-19 in waitlisted patients compared with KTR and a favorable outcome in early COVID-19 in KTR. Our report will help the transplant physicians in dealing with the ongoing dilemma of halting or resuming transplantation in the COVID-19 era.     

Long-term outcomes in COVID-19 patients admitted to intensive care in Denmark: A nationwide observational study

Background

Among ICU patients with COVID-19, it is largely unknown how the overall outcome and resource use have changed with time, different genetic variants, and vaccination status.

Methods

For all Danish ICU patients with COVID-19 from March 10, 2020 to March 31, 2022, we manually retrieved data on demographics, comorbidities, vaccination status, use of life support, length of stay, and vital status from medical records. We compared patients based on the period of admittance and vaccination status and described changes in epidemiology related to the Omicron variant.

Results

Among all 2167 ICU patients with COVID-19, 327 were admitted during the first (March 10–19, 2020), 1053 during the second (May 20, 2020 to June 30, 2021) and 787 during the third wave (July 1, 2021 to March 31, 2022). We observed changes over the three waves in age (median 72 vs. 68 vs. 65 years), use of invasive mechanical ventilation (81% vs. 58% vs. 51%), renal replacement therapy (26% vs. 13% vs. 12%), extracorporeal membrane oxygenation (7% vs. 3% vs. 2%), duration of invasive mechanical ventilation (median 13 vs. 13 vs. 9 days) and ICU length of stay (median 13 vs. 10 vs. 7 days). Despite these changes, 90-day mortality remained constant (36% vs. 35% vs. 33%). Vaccination rates among ICU patients were 42% as compared to 80% in society. Unvaccinated versus vaccinated patients were younger (median 57 vs. 73 years), had less comorbidity (50% vs. 78%), and had lower 90-day mortality (29% vs. 51%). Patient characteristics changed significantly after the Omicron variant became dominant including a decrease in the use of COVID-specific pharmacological agents from 95% to 69%.

Conclusions

In Danish ICUs, the use of life support declined, while mortality seemed unchanged throughout the three waves of COVID-19. Vaccination rates were lower among ICU patients than in society, but the selected group of vaccinated patients admitted to the ICU still had very severe disease courses. When the Omicron variant became dominant a lower fraction of SARS-CoV-2 positive patients received COVID treatment indicating other causes for ICU admission.     

Patients With Previous COVID-19 Infection Can Safely Undergo Primary Total Joint Arthroplasty

BackgroundThe COVID-19 virus is believed to increase the risk of diffusing intravascular coagulation. Total joint arthroplasty (TJA) is one of the most common elective surgeries and is also associated with a temporarily increased risk of venous thromboembolism (VTE). However, the influence of a history of COVID-19 infection on perioperative outcomes following TJA remains unknown. Therefore, this study sought to determine what effect a history of COVID-19 infection had on outcomes following primary TJA.MethodsA retrospective case-control study using the national database was performed to identify all patients who had a history of COVID-19 and had undergone TJA, between 2019 and 2020. Patients who had a history of both were 1:1 matched to those who did not have a history of COVID-19, and 90-day outcomes were compared. A total of 661 TKA and 635 THA patients who had a history of COVID-19 were 1:1 matched to controls. There were no differences in demographics and comorbidities between the propensity-matched pairs in both TKAs and THAs studied. Previous COVID-19 diagnosis was noted in 28.3% of patients 5 days within TJA and in 78.6%, 90 days before TJA.ResultsPatients who had a previous diagnosis of COVID-19 had a higher risk of pneumonia during the postoperative period for both THA and TKA (6.9% versus 3.5%, P < .001 and 2.27% versus 1.21%, P = .04, respectively). Mean lengths of stay were also greater for those with a previous COVID-19 infection in both cohorts (TKA: 3.12 versus 2.57, P = .027, THA: 4.52 versus 3.62, P < .001). Other postoperative outcomes were similar between the 2 groups.ConclusionCOVID-19 infection history does not appear to increase the risk of VTE following primary TJA, but appears to increase the risk of pneumonia in addition to lengths of stay postoperatively. Individual risk factors should be discussed with patients, to set reasonable expectations regarding perioperative outcomes.     

Safety and vasopressor effect of rosuvastatin in septic patients

BackgroundStatins anti-inflammatory and antioxidant properties improve vascular function in septic patients. The aim of this prospective study was to assess vasopressor effect and safety of rosuvastatin therapy in septic patient.MethodsOne hundred and eight patients admitted to intensive care unit (ICU) with suspected or confirmed infection plus at least 2 systemic inflammatory response syndrome criteria were included in this prospective double-blinded randomized two groups’ parallel study. Group R received standard therapy and rosuvastatin 20 mg/day and Group C received standard therapy with placebo/day for 14 days.The primary endpoint was number of acceptable blood pressure and systemic perfusion days (ABPSPD). Secondary outcome included time to initial ABPSPD, vasopressor dose and duration, arterial lactate, organ dysfunction or failure free days, ICU and hospital stay, 28 ICU and hospital mortality, CPK and transaminases level.ResultsThe number of ABPSPD was significantly increased 11(3) vs. 8 (3) (p = 0.0001), with a shorter time to initial ABPSPD 18(21) vs. 41(37) h (p = 0.0001) in Group R than Group C. Norepinephrine dose 0.8 (0.5) vs. 1.6 (0.6) and duration 3(2) vs. 6(3) were significantly reduced in Group R with no significant elevation in transaminases or CPK.ConclusionsRosuvastatin 20 mg/day in septic patients increased number ABPSPD, decreased time to initial ABPSPD, norepinephrine dose and duration, with no significant elevation in transaminases or CPK.     

Prognostic predictors in patients with sepsis after gastrointestinal tumor surgery: A retrospective study

BACKGROUNDThere have been different reports on mortality of sepsis; however, few focus on the prognosis of patients with sepsis after surgery.AIMTo study the clinical features and prognostic predictors in patients with sepsis after gastrointestinal tumor surgery in intensive care unit (ICU).METHODSWe retrospectively screened patients who underwent gastrointestinal tumor surgery at Peking University Cancer Hospital from January 2015 to December 2019. Among them, 181 patients who were diagnosed with sepsis in ICU were included in our study. Survival was analysed by the Kaplan-Meier method. Univariate and multivariate adjusted analyses were performed to identify predictors of prognosis.RESULTSThe 90-d all-cause mortality rate was 11.1% in our study. Univariate analysis showed that body mass index (BMI), shock within 48 h after ICU admission, leukocyte count, lymphocyte to neutrophil ratio, international normalized ratio, creatinine, procalcitonin, lactic acid, oxygenation index, and sequential organ failure assessment (SOFA) score within 24 h after ICU admission might be all significantly associated with the prognosis of sepsis after gastrointestinal tumor surgery. In multiple analysis, we found that BMI ≤ 20 kg/m², lactic acid after ICU admission, and SOFA score within 24 h after ICU admission might be independent risk predictors of the prognosis of sepsis after gastrointestinal tumor surgery. Compared with SOFA score, SOFA score combined with BMI and lactic acid might have higher predictive ability (area under the receiver operating characteristic curve, 0.859; 95% confidence interval, 0.789-0.929).CONCLUSIONLactic acid and SOFA score within 24 h after ICU admission are independent risk predictors of the prognosis of sepsis after gastrointestinal tumor surgery. SOFA score combined with BMI and lactic acid might have good predictive value.
