Low vitamin D blood levels are associated with high mortality in critically ill patients. There is controversy about vitamin D supplementation in this population. The objective of this meta-analysis was to evaluate if vitamin D administration reduces mortality in critically ill patients. Online databases were searched up to September 1st, 2016 for randomized placebo-controlled trials on the use of vitamin D in adult patients with critical illness. The primary end point was mortality among trials with low risk of bias. The secondary end points were length of hospital stay, length of intensive care unit stay, length of mechanical ventilation, and adverse events. Seven studies published between 2011 and 2016, for a total of 716 patients, were included in the analysis. Vitamin D administration was associated with significantly lower mortality compared with placebo (101/320 [32%] in the vitamin D group vs 123/307 [40%] in the placebo group; odds ratio, 0.70 [95% confidence interval, 0.50 to 0.98]; P=.04; I2=0%). No differences in adverse events and other secondary end points were found. In critically ill patients, vitamin D administration might be associated with a reduction in mortality without significant adverse events. A large multicenter randomized trial should conclusively confirm these findings.

ObjectivesTo evaluate the methodological quality of randomised controlled trial (RCT) abstracts in leading critical care nursing journals against the Consolidated Standards of Reporting Trials-Abstracts (CONSORT-A) checklist and to identify variables related with abstract reporting quality.DesignDescriptive methodological quality review.Data sourceWe searched the PubMed database and the websites of each included journal.Eligibility criteriaWe included RCT abstracts published between 2011 and 2021 in the first 11 Scopus-ranking (2021) critical care nursing journals that reported the results of RCTs in English that referred to the care of adult patients with acute/critical illness or their relatives and/or caregivers and conducted in ICUs.Data extraction and synthesisTwo independent investigators extracted the data using a prespecified 17-item checklist directly derived from CONSORT-A. For the primary outcome, each item was evaluated whether it was adequately reported or not and descriptive statistics were reported. An overall score was calculated by summing the results of all items and multivariate linear regression was conducted to detect potential predictors.ResultsSeventy-eight RCT abstracts were included in this review. The items with the highest CONSORT-A adherence were authors, objective, conclusion, participants, interventions and outcome. The randomisation item had the lowest CONSORT-A adherence, followed by trial registration, funding source, harms or side effects, recruitment, blinding and outcome results. The average CONSORT-A score was 8.5±1.5 points (of the maximum 17.5 points). Multivariate analysis indicated that the categorised word score and publication date were positively associated with the overall CONSORT-A score, while the first author’s country being in Asia was negatively associated with the overall CONSORT-A score.ConclusionsThe 78 RCT abstracts showed poor overall adherence to CONSORT-A. The results indicate that the methodological reporting quality of RCT abstracts in critical care nursing journals requires improvement to facilitate assessment of the applicability and relevance of the results reported.

The diagnosis of superior vena cava (SVC) syndrome is always challenging, even more so when it happens intraoperatively. An usual transgastric‐transesophageal projection allows for the visualization and quantification of caval flow acceleration, critical in leading to rapid diagnosis and quick reaction in the operative setting. We present the case of a patient who underwent successful mitral valve reconstruction and left atrial appendage closure via median sternotomy on cardiopulmonary bypass and, intraoperatively, developed iatrogenic SVC syndrome with hypotension, facial cyanosis, and conjunctival edema. We used an uncommon deep transgastric‐transesophageal echocardiographic projection, which proved crucial in promptly identifying SVC stenosis and in immediate intraoperative management. Our case report shows the efficacy of this dedicated deep‐transgastric view, which may be included as part of a routine echocardiographic exam in operations that require bicaval cannulation, leading to increased risk of acute SVC stenosis.

Objectives: This study aims to explore the experiences of bereaved family members during and after the loss of a relative in an intensive care unit (ICU) during the COVID-19 pandemic-related visitation restrictions, as well as to assess their perceptions of a nurse-led bereavement support programme. Methods: Ten participants with a relative who had died in an ICU were recruited in September 2020 during a follow-up bereavement meeting at a tertiary cardiac centre in Switzerland. Descriptive qualitative research was conducted. Face-to-face nurse-led follow-up bereavement meetings, adapted to the pandemic circumstances and conducted as semi-structured interviews, were analysed by a thematic analysis. Findings: Fifteen sub-themes and three main categories were identified. The motivation behind the family members’ participation in the meetings was to ask and learn about their experiences regarding the death of their relative during this abnormal time. The reactions to the meetings varied among the families. Many expressed that the experience of bereavement was particularly challenging and painful, and that the absence of a final farewell to their loved one, as well as the impossibility of having a formally held funeral, made the deaths harder to accept. The families appreciated the interview as it gave them clarification, information, and an awareness of the facts and the care provided, and for several of them it was also a chance to share their emotions and express any difficulties they might have encountered both during and after the patient’s death. Conclusion: The COVID-19 pandemic’s restrictions had a profound impact on families who lost a loved one in an ICU. The nurse-led bereavement support service responded to the needs of grieving families, providing valuable emotional and practical support and re-establishing a healthy relationship between the families and the caregivers that was hindered by pandemic restrictions. The study also shows that a nurse-led bereavement support service can be a valuable component of family-centred care.

Introduction: Ventricular dysfunction requiring inotropic support frequently occurs after cardiac surgery, and the associated low cardiac output syndrome largely contributes to postoperative death. We aimed to study the incidence and potential risk factors of postcardiotomy ventricular dysfunction (PCVD) in moderate-to-high risk patients scheduled for open-heart surgery. Methods: Over a 5-year period, we prospectively enrolled 295 consecutive patients undergoing valve replacement for severe aortic stenosis or coronary artery bypass surgery who presented with Bernstein-Parsonnet scores >7. The primary outcome was the occurrence of PCVD as defined by the need for sustained inotropic drug support and by transesophageal echography. The secondary outcomes included in-hospital mortality and the incidence of any major adverse events as well as Intensive Care Unit (ICU) and hospital length of stay. Results: The incidence of PCVD was 28.4%. Patients with PCVD experienced higher in-hospital mortality (12.6% vs. 0.6% in patients without PCVD) with a higher incidence of cardiopulmonary and renal complications as well as a prolonged stay in ICU (median + 2 days). Myocardial infarct occurred more frequently in patients with PCVD than in those without PCVD (19 [30.2%] vs. 12 [7.6%]). By logistic regression analysis, we identified four independent predictors of PCVD: left ventricular ejection fraction <40% (odds ratio [OR] = 6.36; 95% confidence interval [CI], 2.59-15.60), age older than 75 years (OR = 3.35; 95% CI, 1.64-6.81), prolonged aortic clamping time (OR = 3.72; 95% CI, 1.66-8.36), and perioperative bleeding (OR = 2.33; 95% CI, 1.01-5.41). The infusion of glucose-insulin-potassium was associated with lower risk of PCVD (OR = 0.14; 95% CI, 0.06-0.33). Conclusions: This cohort study indicates that age, preoperative ventricular function, myocardial ischemic time, and perioperative bleeding are predictors of PCVD which is associated with poor clinical outcome.

Serum neurofilament light (sNfL) is a promising marker of outcome after cardiac arrest, but its kinetics are unclear. We prospectively measured sNfL concentrations in 62 patients at 0, 1, 3, 5, 7 and 10 days after cardiac arrest. Survivors and non‐survivors had similar sNfL at admission (14.2 [8.6–21.9] vs. 22.5 [14.2–46.9] pg/mL) but largely different at 24 h (16.4 [10.2–293] vs. 464.3 [151.8–1658.2], respectively). The AUC for sNfL concentrations predicting death was above 0.95 from Day 1 to 10 (highest on Day 3). Late sNfL measurements may exert prognostic value, especially when early samples are unavailable or prognosis remains unclear.

Despite a relative contraindication, mechanical support with Impella™ left ventricular assist device has already been described for ischaemic ventricular septal defect treatment, either as a bridge to surgery, as intraoperative mechanical haemodynamic support, or to ensure intraprocedural haemodynamic stability during device closure. We describe two cases of ventricular septal defect complicating acute myocardial infarction, where the percutaneous ImpellaCP was implanted early (differently than previously described) with the aim of preventing haemodynamic instability, while deferring surgical repair. We present a report of haemodynamic, echocardiographic, biochemical, and clinical data of two consecutive cases of ImpellaCP use, within a minimally invasive monitoring and therapeutic approach. In two cases of subacute myocardial infarction‐related ventricular septal defect not amenable to percutaneous device closure, the use ImpellaCP was successful: it was followed by effective and rapid right and left ventricular unloading, by major haemodynamic instability prevention and protection from systemic venous congestion, from kidney and splanchnic organ failures. This allowed bridging to appropriately timed surgical repair. These cases suggest a potentially effective, clinically grounded strategy in the early management of ischaemic ventricular septal defect patients, with the aim of deferring surgery beyond the safer 7 days cutoff associated with a lower perioperative mortality.

Objective: Transcatheter aortic valve replacement (TAVR) through alternative access routes is indicated in patients with severe aortic valve stenosis and diseased peripheral arteries. We analysed and compared the outcome of patients undergoing transapical (TA) and direct transaortic (TAO) TAVR procedures. Methods: Preoperative characteristics, procedural details, and thirty-day outcome of patients undergoing transapical (TA-TAVR group) and direct transaortic (TAO-TAVR group) TAVR procedures were prospectively collected and retrospectively analysed. Results: From March 2012 to March 2022, 81 TA and 82 TAO-TAVR (total: 163 cases) were performed with balloon-expanding (n = 120; 73.6%) and self-expandable (n = 43; 26.4%) valves. The mean age was 79.7 ± 6.2 and 81.9 ± 6.7 years for the TA- and TAO-TAVR groups, respectively (p = 0.032). Females were more represented in the TAO-TAVR group (56% vs. 32%; p = 0.003) while TA-TAVR patients showed a higher prevalence of previous vascular surgery (20% vs. 6%; p = 0.01), previous cardiac surgery (51% vs. 3.6%; p < 0.001), and porcelain aorta (22% vs. 5%; p = 0.001). The mean ejection fraction was 49.0 ± 14.6% (TA) and 53.5 ± 12.2% (TAO) (p = 0.035) while mean gradients were 35.6 ± 13.2 mmHg (TA) and 40.4 ± 16.1 mmHg (TAO) (p = 0.045). The median EuroSCORE-II was 5.0% (IQR: 3.0–11.0) and 3.9% (IQR: 2.5–5.4) for the TA- and TAO-TAVR groups, respectively (p = 0.005). The procedural time was shorter for TA procedures (97 min (IQR: 882–118) vs. 102 min (IQR: 88–129); p = 0.133). Mortality at day 30 was 6% in both groups (p = 1.000); the permanent pacemaker implantation rate was similar (8.6% vs. 9.7%; p = 1.000), and hospital stay was shorter for the TAO group (8 days (IQR: 6–11) vs. 10 days (IQR: 7–13); p = 0.025). Conclusions: Our results show that transapical and direct transaortic TAVR in high-risk patients with diseased peripheral arteries provide satisfactory clinical results with similar thirty-day outcomes.

Limited data are available on the diagnostic performance of contemporary ECG interpretation criteria in master athletes (aged over 35 years). This study aimed to describe ECG findings and compare the diagnostic accuracy of the 2017 International, 2010 ESC, and 2013 Seattle criteria in identifying high-risk cardiovascular conditions in a cohort of competitive master athletes. We included 506 consecutive Caucasian master athletes (mean age, 47.9 ± 8.7 years; 85.6% male) who underwent ECG-based preparticipation screening. ECGs were retrospectively interpreted according to the three criteria. Transthoracic echocardiography was included to calculate sensitivity and specificity. Thirteen athletes (2.5%) were diagnosed with a condition potentially related to sudden cardiac death (SCD), including severe aortic regurgitation (  = 1), Type 1 Brugada pattern (  = 1), chronic coronary syndromes (  = 4), dilated cardiomyopathy (DCM) (  = 3), aortic dilation (  = 3), and moderate aortic stenosis (  = 1). Diagnostic accuracy for conditions at risk of SCD was 0.73 for International, 0.81 for Seattle, and 0.77 for ESC criteria. Seattle demonstrated a significantly higher AUC than the International criteria (  = 0.0032). The International criteria failed to identify two athletes with DCM and left axis deviation, while no significant structural abnormalities were found in athletes with complete right bundle branch block (RBBB). The most common ECG abnormalities were left axis deviation (7.1%), left atrial enlargement (4.2%), and T-wave inversion (3%). A prolonged QT interval was diagnosed in 5.7% according to ESC criteria but in only one athlete under the International and Seattle criteria. The Seattle criteria demonstrated the highest overall accuracy, with significantly better discriminative performance than the International criteria, and a lower false-positive rate compared with the ESC criteria. These findings support the use of the Seattle criteria as part of a comprehensive screening strategy in master athletes.

Background: Active mobilization is a key component in fast-track surgical strategies. Following major surgery, clinicians are often reluctant to mobilize patients arguing that circulatory homeostasis would be impaired as a result of myocardial stunning, fluid shift, and autonomic dysfunction. Aims: We examined the feasibility and safety of a mobilization protocol 12-24 h after elective cardiac surgery. Setting and Design: This observational study was performed in a tertiary nonacademic cardiovascular Intensive Care Unit. Materials and Methods: Over a 6-month period, we prospectively evaluated the hemodynamic response to a two-staged mobilization procedure in 53 consecutive patients. Before, during, and after the mobilization, hemodynamics parameters were recorded, including the central venous oxygen saturation (ScvO 2 ), lactate concentrations, mean arterial pressure (MAP), heart rate (HR), right atrial pressure (RAP), and arterial oxygen saturation (SpO 2 ). Any adverse events were documented. Results: All patients successfully completed the mobilization procedure. Compared with the supine position, mobilization induced significant increases in arterial lactate (34.6% [31.6%, 47.6%], P = 0.0022) along with reduction in RAP (−33% [−21%, −45%], P < 0.0001) and ScvO 2 (−7.4% [−5.9%, −9.9%], P = 0.0002), whereas HR and SpO 2 were unchanged. Eighteen patients (34%) presented a decrease in MAP > 10% and nine of them (17%) required treatment. Hypotensive patients experienced a greater decrease in ScvO 2 (−18 ± 5% vs. −9 ± 4%, P = 0.004) with similar changes in RAP and HR. All hemodynamic parameters, but arterial lactate, recovered baseline values after resuming the horizontal position. Conclusions: Early mobilization after cardiac surgery appears to be a safe procedure as far as it is performed under close hemodynamic and clinical monitoring in an intensive care setting.
