Abstract Background The results of surgical treatment of type A aortic dissection (AAD) in the elderly are controversial and aggravated by a higher operative mortality rate. The studies published in this subset of patients are mainly retrospective analyses or small samples from international registries. We sought to investigate this topic by conducting a contemporary meta-analysis of the most recent observational studies. Methods A systematic literature search was conducted for any study published from the inception till August 2019 on aortic dissection treated surgically in patients 70 years and older. A pooled risk-ratio meta-analysis has been conducted three main post-operative outcomes: short-term mortality, stroke and acute kidney injury. Results A total of 23 retrospective observational studies have been included in the metaanalysis. Pooled meta-analysis showed an increased risk of short-term mortality for the elderly population [relative risk (RR) =1.39; 95% CI, 0.64–3.5; I2=92%; P < 0.001], and this has been confirmed in a sub-analysis of patients 80 years and older. The risk of having stroke (RR = 1.47; 95% CI, 0.66–3.29; I2=91%; P = 0.35) and acute kidney injury (RR = 1.12; 95% CI, 0.32–3.9, I2=90%, P = 0.85) after surgery were comparable to the conservative treatment of patients. Conclusion Although affected by an increased risk of short-term mortality in the elderly, surgical repair remains the treatment of choice for AAD. The main post-operative outcomes are comparable to younger patients and the mid-term survival rates are acceptable.

Abstract Background: In the current SARS-CoV-2 pandemic, there has been worldwide debate on the use of corticosteroids in COVID-19. In the recent RECOVERY trial, evaluating the effect of dexamethasone, a reduced 28-day mortality in patients requiring oxygen therapy or mechanical ventilation was shown. Their results have led to considering amendments in guidelines or actually already recommending corticosteroids in COVID-19. However, the effectiveness and safety of corticosteroids still remain uncertain, and reliable data to further shed light on the benefit and harm are needed. Objectives: The aim of this systematic review and meta-analysis was to evaluate the effectiveness and safety of corticosteroids in COVID-19. Methods: A systematic literature search of RCTS and observational studies on adult patients was performed across Medline/PubMed, Embase, and Web of Science from 1st of December 2019 until 1 st of October 2020, according to the PRISMA guidelines. Primary outcomes were short-term mortality and viral clearance (based on RT-PCR in respiratory specimens). Secondary outcomes were: need for mechanical ventilation, other oxygen therapy, length of hospital stay and secondary infections. Results: Forty-four studies were included, covering 20.197 patients. In twenty-two studies, the effect of corticosteroid use on mortality was quantified. The overall pooled estimate (observational studies and RCTs) showed a significant reduced mortality in the corticosteroid group (OR 0.72 (95%CI 0.57-0.87). Furthermore, viral clearance time ranged from 10-29 days in the corticosteroid group and from 8-24 days in the standard of care group. Fourteen studies reported a positive effect of corticosteroids on need for and duration of mechanical ventilation. A trend towards more infections and antibiotic use was present. Conclusions: Our findings from both observational studies and RCTs confirm a beneficial effect of corticosteroids on short-term mortality and a reduction of need for mechanical ventilation. And although data in the studies were too sparse to draw any firm conclusions, there might be a signal of delayed viral clearance and an increase in secondary infections.

Acute cardiovascular disease after community-acquired pneumonia is a well-accepted complication for which definitive treatment strategies are lacking. These complications share some common features but have distinct diagnostic and treatment approaches. We therefore undertook an updated systematic review and meta-analysis of observational studies reporting the incidence of overall complications, acute coronary syndromes, new or worsening heart failure, new or worsening arrhythmias and acute stroke, as well as short-term mortality outcomes. To set a framework for future research, we further included a holistic review of the interplay between the two conditions. From 1984 to 2019, thirty-nine studies were accrued, involving 92,188 patients, divided by setting (inpatients versus outpatients) and clinical severity (low risk versus high risk). Overall cardiac complications occurred in 13.9% (95% confidence interval (CI) 9.6–18.9), acute coronary syndromes in 4.5% (95% CI 2.9–6.5), heart failure in 9.2% (95% CI 6.7–12.2), arrhythmias in 7.2% (95% CI 5.6–9.0) and stroke in 0.71% (95% CI 0.1–3.9) of pooled inpatients. During this period, meta-regression analysis suggests that the incidence of overall and individual cardiac complications is decreasing. After adjusting for confounders, cardiovascular events taking place after community-acquired pneumonia independently increase the risk for short-term mortality (range of odds-ratio: 1.39–5.49). These findings highlight the need for effective, large trial based, preventive and therapeutic interventions in this important patient population.

Background: Cognitive impairment is one of the most common, burdensome, and costly disorders in the elderly worldwide. The magnitude of the association between anemia and overall cognitive impairment (OCI) has not been established. Objective: We aimed to update and expand previous evidence of the association between anemia and the risk of OCI. Methods: We conducted an updated systematic review and meta-analysis. We searched electronic databases, including EMBASE, PubMed, and Web of Science for published observational studies and clinical trials between 1 January 1990 and 1 June 2020. We excluded articles that were in the form of a review, letter to editors, short reports, and studies with less than 50 participants. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. We estimated summary risk ratios (RRs) with random effects. Results: A total of 20 studies, involving 6558 OCI patients were included. Anemia was significantly associated with an increased risk of OCI (adjusted RR (aRR) 1.39 (95% CI, 1.25–1.55; p < 0.001)). In subgroup analysis, anemia was also associated with an increased risk of all-cause dementia (adjusted RR (aRR), 1.39 (95% CI, 1.23–1.56; p < 0.001)), Alzheimer’s disease [aRR, 1.59 (95% CI, 1.18–2.13; p = 0.002)], and mild cognitive impairment (aRR, 1.36 (95% CI, 1.04–1.78; p = 0.02)). Conclusion: This updated meta-analysis shows that patients with anemia appear to have a nearly 1.39-fold risk of developing OCI than those without anemia. The magnitude of this risk underscores the importance of improving anemia patients’ health outcomes, particularly in elderly patients.

Abstract Introduction Cardiogenic shock is linked with eminent morbidity and mortality despite advances in treatment modality. Adjuvant treatment modalities to provide mechanical haemodynamic support in the form of intra-aortic balloon pump (IABP) or Impella are being used among patients with cardiogenic shock. The Impella prunes left ventricular preload, whereas, IABP persuades after load reduction and both contribute to improved cardiac output. A few underpowered randomised control trials (RCTs) and observational studies compared short term mortality benefit of Impella juxtaposed to IABP among patients with cardiogenic shock. Purpose A meta-analysis of RCTs and observational studies researching the short-term mortality in cardiogenic shock comparing Impella to IABP was executed. Methods The databases PubMed, EMBASE and Cochrane were searched systematically to identify relevant RCTs and observational studies contrasting Impella to IABP and reporting 30-days mortality as outcomes. The search terms used were “Impella”, “IAPB”, “intra-aortic balloon pump” and all word variations were utilised. The search was conducted from the debut of the databases up to January 2020. Two reviewers independently and in tandem performed data screening and extraction from identified articles. Inverse variance method with Paule-Mandel estimator for tau2 and Hartung-Knapp adjustment was used to calculate Risk Ratio with 95% confidence interval. Heterogeneity was assessed using I2 statistics. Furthermore, we calculated the 95% predictive interval for the pooled estimate. All statistical analysis for this meta-analysis was carried out using R statistical software version 3.6.2 using the package meta ( ). Additionally, Grading of Recommendations, Assessment, Development and Evaluations (GRADE) criteria were used to assess the certainty of evidence. Results Five studies constituting 728 patients were included in the final analysis. Two were RCTs (ISAR-SHOCK trial and IMPRESS in Severe Shock trial), one study was a propensity score matched observational study and two were unmatched observational studies. There was no difference in the risk of 30-days mortality in patients treated with Impella as compared to IABP [Risk Ratio: 0.97, 95% confidence interval: 0.66–1.41, I2: 32%]. To account for the heterogeneity, we calculated 95% predictive interval: 0.46–2.02. Thus, very low certainty of evidence concluded no difference in the risk of 30-days mortality among cardiogenic shock patients treated with Impella in opposition to IABP. Conclusion This meta-analysis comparing Impella juxtaposed with IABP demonstrated no difference in the risk of 30-days mortality among patients with cardiogenic shock. 30-days Mortality Funding Acknowledgement Type of funding source: None

Abstract Background Acute kidney injury (AKI) is one of the most common complications after Stanford type A aortic dissection (TAAD) repair surgery, but its risk factors are inconsistent in different studies. So this meta-analysis was conducted to systematically analyze the risk factors for AKI after TAAD repair surgery, so as to early identify the therapeutic targets for preventing AKI and to improve the outcomes. Methods Studies on risk factors for AKI after TAAD repair surgery were searched from PubMed, Embase, Cochrane library and Web of science from inception of databases to June 2021. The meta-analysis was performed by Stata 16.0 software. The combined incidence and risk factors of AKI and its impact on mortality after TAAD repair surgery were calculated. Results A total of 11 studies and 4156 patients were included. The combined incidence of postoperative AKI was 56.0%. The advanced age [odds ratio (OR)=1.32, 95% confidence interval (CI) (1.19, 1.47), P<0.001], cardiopulmonary bypass time > 180 minutes [OR=4.88, 95% CI (2.05, 11.59), P<0.001], red blood cell (RBC) volume transfused perioperatively [OR=1.13, 95% CI (1.03, 1.24), P<0.01], high body mass index [OR=1.22, 95% CI (1.18, 1.27), P<0.001] and preoperative renal malperfusion [OR= 5.32, 95% CI (2.92, 9.71), P<0.001] were risk factors for AKI after TAAD repair surgery. The in-hospital mortality [rate ratio (RR)=2.50, 95% CI (1.82, 3.44), P<0.001] and 30-day mortality [RR=2.81, 95% CI (1.95, 4.06), P<0.001] were higher in patients with postoperative AKI than that without AKI. Conclusions The incidence of AKI after TAAD repair surgery was high, and it increased the in-hospital and 30-day mortality. Reducing cardiopulmonary bypass time and RBC transfusions perioperatively, especially in elderly or patients with high body mass index, or patients with renal malperfusion preoperatively were important to prevent AKI after TAAD repair surgery.Systematic review registration number: INPLASY 202060100.

Background: The prevalence and prognostic implications of metabolic syndrome (MetS) in patients infected by the SARS-CoV-2 remain unclear. We performed a systematic review and meta-analysis of prevalence and mortality risk in COVID-19 patients with MetS. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed in abstracting data and assessing validity. We searched MEDLINE and Scopus to locate every article published up to 1 September 2021, reporting data on MetS among COVID-19 patients. The pooled prevalence of MetS was calculated using a random effects model and presented using the related 95% confidence interval (CI), while the mortality risk was estimated using the Mantel-Haenszel random effects models with odds ratio (OR) and related 95% CI. Statistical heterogeneity was measured using the Higgins I2 statistic. Results: Six studies, enrolling 209.569 COVID-19 patients [mean age 57.2 years, 114.188 males (54.4%)] met the inclusion criteria and were included in the final analysis. The pooled prevalence of dyslipidaemia was 20.5% of cases (95% CI: 6.7–47.8%, p = 0.03), with high heterogeneity (I2 = 98.9%). Pre-existing MetS was significantly associated with higher risk of short-term mortality (OR: 2.30, 95% CI: 1.52–3.45, p < 0.001), with high heterogeneity (I2 = 89.4%). Meta-regression showed a direct correlation with male gender (p = 0.03), hypertension (p < 0.001), DM (p = 0.01) and hyperlipidaemia (p = 0.04), but no effect when considering age (p = 0.75) and chronic pulmonary disease (p = 0.86) as moderators. Conclusions: MetS represents a major comorbidity in about 20% of COVID-19 patients and it is associated with a 230% increased risk of short-term mortality.

Abstract Background Transcatheter aortic valve implantation (TAVI) is a safe and effective procedure for patients with symptomatic aortic stenosis who do not qualify for surgery. Nevertheless, post-procedure acute kidney injury (AKI) is a frequent complication and it is associated with worse outcomes. Aim To assess the impact of acute kidney injury (AKI) occurring immediately after the TAVI procedure on patients' outcome. Methods We conducted a multicenter retrospective study on patients treated with TAVI from 2010 to 2018. The assigned treatment, the selection of the device (self-expandable/balloon-expandable valve) and the type of approach used were determined by each individual Center on the basis of the patient's characteristics and the choice of the operator. All patients had an intermediate or high Society of Thoracic Surgeons (STS) score. Basal creatinine and glomerular filtrate (using the body mass index, sex and age) were evaluated for each patient. According to the KDIGO criteria, AKI is defined as an increase in serum creatinine (SCr) ≥0,3mg/dl within 48 hours or an increase in SCr ≥1.5 times baseline or urine volume <0,5ml/kg/h for 6 hours. The incidence of post procedural AKI and its correlation with the short-term mortality and outcomes was evaluated as primary end point (stroke/TIA/RIND, cardiac tamponade, bleeding, vascular complications, cardiocirculatory arrest with subsequent ROSC, definitive pacemaker implantation, postoperative atrial fibrillation, left bundle branch block de novo).Postoperative outcomes were defined according to the updated Valve Academic Research Consortium 2 definitions Results A total of 371 pts were analysed. Mean age was 82.3±5.9 and the majority of the pts had an STS score>10 (97.6%). Incidence of Acute kidney Injury (AKI) stage 3 post TAVI, according to VARC-2 criteria, was 16,2%. In patient with AKI, the hospitalization time was longer 18,7±6,1 days vs 8,4±6,1 days without AKI (p<0,01). Patients with AKI had an increased risk of in hospital mortality (OR 50,0; 95% CI 5,2–390,16; p<0,01) and 30 day mortality (OR: 5,88; 95% CI 2,08–16,60; p<0,01). Acute Kidney Injury instead was more common in patients treated with transapical access (OD 3,9-CI 95% 2,16–7,07; p<0,01) or with PAD (OR 1,87 - CI 95% 1,03–3,41; p=0,03) AKI and short term mortality Conclusion Acute kidney injury is a frequent complication after TAVI. AKI seems to be the strongest predictor for 30 day mortality and increases the hospitalization time. AKI was more common in patients treated with a transapical approach or if they presented a PAD. In contrast, pre-procedural chronic kidney disease did not seem to correlate directly with an increased risk of AKI.

Abstract Critically ill patients who develop acute kidney injury (AKI) are more than twice as likely to die in hospital. However, it is not clear to what extent AKI is the cause of excess mortality, or merely a correlate of illness severity. The Bradford Hill criteria for causality (plausibility, temporality, magnitude, specificity, analogy, experiment & coherence, biological gradient and consistency) were applied to assess the extent to which AKI may be causative in adverse short-term outcomes of critical illness. Plausible mechanisms exist to explain increased risk of death after AKI, both from direct pathophysiological effects of renal dysfunction and mechanisms of organ cross-talk in multiple-organ failure. The temporal relationship between increased mortality following AKI is consistent with its pathophysiology. AKI is associated with substantially increased mortality, an association that persists after accounting for known confounders. A biological gradient exists between increasing severity of AKI and increasing short-term mortality. This graded association shares similar features to the increased mortality observed in ARDS; an analogous condition with a multifactorial aetiology. Evidence for the outcomes of AKI from retrospective cohort studies and experimental animal models is coherent however both of these forms of evidence have intrinsic biases and shortcomings. The relationship between AKI and risk of death is maintained across a range of patient ages, comorbidities and underlying diagnoses. In conclusion many features of the relationship between AKI and short-term mortality suggest causality. Prevention and mitigation of AKI and its complications are valid targets for studies seeking to improve short-term survival in critical care.
