Deciphering the Therapeutic Potential of Myeloid-Specific JAK2 Inhibition in Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome (ARDS) is a life-threatening condition characterized by severe inflammation and pulmonary dysfunction. Despite advancements in critical care, effective pharmacological interventions for ARDS remain elusive. While Janus kinase 2 (JAK2) inhibitors have emerged as an innovative treatment for numerous autoinflammatory diseases, their therapeutic potential in ARDS remains unexplored. In this study, we investigated the contribution of JAK2 and its underlying mechanisms in ARDS utilizing myeloid-specific JAK2 knockout murine models alongside a pharmacological JAK2 inhibitor. Notably, myeloid-specific JAK2 knockout led to a notable attenuation of ARDS induced by intratracheal administration of LPS, accompanied by reduced levels of neutrophils and inflammatory cytokines in bronchoalveolar lavage fluid (BALF) and lung tissue. Intriguingly, the ameliorative effects were abolished upon the depletion of monocyte-derived alveolar macrophages (Mo-AMs) rather than tissue-resident alveolar macrophages (TR-AMs). JAK2 deficiency markedly reversed LPS-induced activation of STAT5 in macrophages. Remarkably, pharmacological JAK2 inhibition using baricitinib failed to substantially alleviate neutrophils infiltration, implying that specific inhibition of JAK2 in Mo-AMs is imperative for ARDS amelioration. Collectively, our data suggest that JAK2 may mitigate ARDS progression through the JAK2 pathway in Mo-AMs, underscoring JAK2 in alveolar macrophages, particularly Mo-AMs, as a promising therapeutic target for ARDS treatment.

The nasal microbiota is a potential diagnostic biomarker for sepsis in critical care units.

This study aimed to characterize the composition of intestinal and nasal microbiota in septic patients and identify potential microbial biomarkers for diagnosis. A total of 157 subjects, including 89 with sepsis, were enrolled from the affiliated hospital. Nasal swabs and fecal specimens were collected from septic and non-septic patients in the intensive care unit (ICU) and Department of Respiratory and Critical Care Medicine. DNA was extracted, and the V4 region of the 16S rRNA gene was amplified and sequenced using Illumina technology. Bioinformatics analysis, statistical processing, and machine learning techniques were employed to differentiate between septic and non-septic patients. The nasal microbiota of septic patients exhibited significantly lower community richness (P = 0.002) and distinct compositions (P = 0.001) compared to non-septic patients. Corynebacterium, Staphylococcus, Acinetobacter, and Pseudomonas were identified as enriched genera in the nasal microbiota of septic patients. The constructed machine learning model achieved an area under the curve (AUC) of 89.08, indicating its efficacy in differentiating septic and non-septic patients. Importantly, model validation demonstrated the effectiveness of the nasal microecological diagnosis prediction model with an AUC of 84.79, while the gut microecological diagnosis prediction model had poor predictive performance (AUC = 49.24). The nasal microbiota of ICU patients effectively distinguishes sepsis from non-septic cases and outperforms the gut microbiota. These findings have implications for the development of diagnostic strategies and advancements in critical care medicine.IMPORTANCEThe important clinical significance of this study is that it compared the intestinal and nasal microbiota of sepsis with non-sepsis patients and determined that the nasal microbiota is more effective than the intestinal microbiota in distinguishing patients with sepsis from those without sepsis, based on the difference in the lines of nasal specimens collected.

Assessing Respiratory Tract Infections' Prevalence and Microbial Profiles in Mechanically Ventilated Patients: Insights From Broncho Alveolar Lavage Examination.

Introduction Chest infections represent a significant challenge in mechanically ventilated patients, often leading to adverse outcomes despite advancements in critical care. This prospective study was conducted in the intensive care unit of tertiary referral care, with objectives to assess chest infection prevalence, microbial profiles, and outcomes in mechanically ventilated patients through broncho-alveolar lavage (BAL) examination. Methodology This prospective study involved 38 patientsaged 15 to 65 yearswho were receiving mechanical ventilation and underwent BAL. The procedureof BALwas followed as per the guidelines and recommendations outlined by the American Thoracic Society for Bronchoscopic Lavage. Microbial analysis involves the use of microscopic examination and quantitative culture methods. Different staining techniques were utilized to identify bacteria, fungi, and mycobacteria. Complications and adverse events were monitored and recorded. Results Out of the 38 patients who underwent BAL, the majority, 30 (78.94%), were found to have chest infections, with gram-negative bacteria, including Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii, being the causative agents. The antibiotic sensitivity profiles indicated that the organisms were susceptible to carbapenems and broad-spectrum β-lactam/β-lactamase inhibitor combinations while showing resistance to fluoroquinolones. Despite adequate treatment, mortality remained significant in 12 (31.57%) patients. Conclusion Study findings underscore the importance of proactive surveillance, early diagnosis, and targeted management strategies to mitigate the burden of respiratory infections in critical care settings.

Contemporary national outcomes of hyperbaric oxygen therapy in necrotizing soft tissue infections.

The role of hyperbaric oxygen therapy (HBOT) in necrotizing soft tissue infections (NSTI) is mainly based on small retrospective studies. A previous study using the 1998-2009 National Inpatient Sample (NIS) found HBOT to be associated with decreased mortality in NSTI. Given the argument of advancements in critical care, we aimed to investigate the continued role of HBOT in NSTI. The 2012-2020 National Inpatient Sample (NIS) was queried for NSTI admissions who received surgery. 60,481 patients between 2012-2020 were included, 600 (<1%) underwent HBOT. Primary outcome was in-hospital mortality. Secondary outcomes included amputation, hospital length of stay, and costs. A multivariate model was constructed to account for baseline differences in groups. Age, gender, and comorbidities were similar between the two groups. On bivariate comparison, the HBOT group had lower mortality rate (<2% vs 5.9%, p<0.001) and lower amputation rate (11.8% vs 18.3%, p<0.001) however, longer lengths of stay (16.9 days vs 14.6 days, p<0.001) and higher costs ($54,000 vs $46,000, p<0.001). After multivariate analysis, HBOT was associated with decreased mortality (Adjusted Odds Ratio (AOR) 0.22, 95% CI 0.09-0.53, P<0.001) and lower risk of amputation (AOR 0.73, 95% CI 0.55-0.96, P = 0.03). HBO was associated with longer stays by 1.6 days (95% CI 0.4-2.7 days) and increased costs by $7,800 (95% CI $2,200-$13,300), they also had significantly lower risks of non-home discharges (AOR 0.79, 95%CI 0.65-0.96). After correction for differences, HBOT was associated with decreased mortality, amputations, and non-home discharges in NSTI with the tradeoff of increase to costs and length of stay.

Early Mobilization in Pediatric Critical Care: Exploring the Gap Between Theory and Practice in Saudi Arabia.

BACKGROUND Because of advancements in critical care, Pediatric Intensive Care Units (PICUs) have experienced improved survival rates. However, PICU-acquired frailty and cognitive deficits continue to be issues. In PICUs, early mobilization is emerging as a useful technique. The present study assesses early mobilization awareness, opinions, and practices among pediatric critical care providers in Saudi Arabia. MATERIAL AND METHODS From July 2020 to February 2021, a survey was undertaken in Saudi Arabia, targeting 110 physicians, 200 nurses, 30 respiratory therapists, and 20 physiotherapists. It concentrated on emergency medicine practices, operational issues, initiation time, rehabilitation modalities, and PICU staff strain. RESULTS The results showed that 64.7% of the 266 respondents were nurses, usually working in 5- to 15-bed ICUs providing medical and surgical treatment. Early mobilization was evaluated as highly significant by 40.6% of the respondents. Equipment constraints (63.5%), patient medical instability (67.3%), endotracheal intubation complications (65.4%), and personnel limits (56.4%) were major challenges. Non-physicians cited space constraints 38.9% of the time, whereas physicians cited safety concerns 47.4% of the time. Respiratory physiotherapy and passive range-of-motion exercises were the most used rehabilitation techniques (77.8%). Only 38.7% of patients with ICU-acquired weakness were referred for outpatient therapy. CONCLUSIONS The study emphasizes the importance of early mobilization in Saudi Arabian pediatric critical care while also recognizing considerable limitations. Addressing these difficulties necessitates a multidisciplinary, strategic approach. Future research should strive to standardize practices to enhance patient outcomes and develop standards in pediatric critical care.

Site of Tracheostomy and Its Influence on The Surgical Outcome and Quality of Life After Tracheal Resection and Anastomosis in Patients with Tracheal Stenosis.

Introduction With the advances in critical care, the incidence of post intubation tracheal stenosis is increasing. Tracheal resection and anastomosis have been the gold standard for the management of grades III and IV stenosis. Scientific evidence from the literature on the determining factors and outcomes of surgery is not well described. Objective This study was aimed at determining the influence of tracheostoma site on the surgical outcomes and postoperative quality of life of patients undergoing tracheal resection anastomosis. Methods Thirteen patients who underwent tracheal resection and anastomosis during a period of 3 years were followed up prospectively for 3 months to determine the degree of improvement in their quality of life postsurgery by comparing the pre and postoperative validated Tamil/vernacular version of RAND SF-36 scores and Medical Research Council (MRC) dyspnea score. Results As per preoperative computed tomography (CT), the mean length of stenosis was found to be 1.5 cm while the mean length of trachea resected was 4.75 cm. We achieved a decannulation rate of 61.53%. There was an estimated loss of 3.20 +/- 1.90 cm of normal trachea from the lower border of the stenosis until the lower border of the stoma that was lost during resection. Analysis of SF-36 and MRC dyspnea scores revealed significant improvement in the domains of physical function postoperatively in comparison with the preoperative scores ( p < 0.05). Conclusion Diligent placement of tracheostomy in an emergency setting with respect to the stenotic segment plays a pivotal role in minimizing the length of the resected segment of normal trachea.

Primary Closure Versus Delayed Primary Closure of Class III and IV Surgical Wounds Following Emergency Laparotomy: A Prospective Comparative Study.

Introduction Emergency surgery has a high risk of complications due to the detrimental effect of perioperative sepsis and the relative lack of preoperative optimization of patients. Despite advances in critical care for the management of sepsis, its prevention is dependent on various patient and surgeon factors. Surgical site infection continues to be a major determinant of morbidity and mortality following emergency abdominal surgery, especially in contaminated or dirty wounds. This study aims to compare two techniques of abdominal wall closure, primary closure with subcutaneous suction drains and delayed primary closure following negative pressure wound therapy, in terms of incidence of surgical site infection and morbidity. Materials and methods The study was a prospective comparative study including 50 patients with an acute surgical abdomen requiring laparotomy. The patients were randomized into two groups, Group A (n=25) who underwent primary closure, and Group B (n=25) who underwent delayed primary closure. In Group B patients, a vacuum-assisted closure device was applied in the subcutaneous space for five days prior to the closure of the skin. Outcomes were compared in terms of the incidence of superficial and deep surgical site infection, its association with diabetes mellitus, and the total duration of hospital stay. A chi-square test and an unpaired t-test were used for the test of significance. Results A total of 50 patients, comparable in age, were included in the study. The overall incidence of surgical site infection was significantly higher in patients of Group A as compared to Group B (p=0.0046). There was a positive correlation between diabetes mellitus and the occurrence of wound infection in both groups with the odds ratio being 2.67 and 2.38 respectively. The incidence of superficial wound infection was significantly higher in Group A when compared to Group B (52% versus 24%; p=0.04). Deep surgical site infection was higher in patients of Group A (20% versus 8%) but was not statistically significant (p=0.22). The average duration of hospital stay was 41.56 ± 6.96 and 37.86 ± 6.68 days for patients who developed complications fromGroups A and B respectively, while it was nearly two and a half times lower in uncomplicated cases of Groups A and B (11.71± 1.70 days and 16.58± 1.06 days respectively). The one-tailed unpaired t-test showed a significant difference in means of hospital stay between patients with and without complications (T: 17.06, critical value: 1.677). Conclusion Delayed primary closure is an effective method of managing contaminated and dirty wounds following emergency laparotomy. Negative pressure wound therapy is one technique for preventing wound bed infection and accelerating wound healing in such cases. By combining the above in emergency surgeries, the incidence of surgical site infection and duration of hospital stay can be significantly reduced.

Abstract 19115: In-situ Resuscitation Training in Cardiology Procedural Suites

Background: Critical Care Advanced Resuscitation Training (CC-ART) prepares critical care teams for emergency situations through training that occurs in a simulated clinical space. Simulated environments do not always accurately mirror the actual clinical environments. Simulations conducted in the actual clinical environment, also known as in-situ simulation, may overcome some of these challenges. Goal: To explored the impact of in situ, ART simulation in a Cardiac Catheterization Lab (CCL) and an Electrophysiology Lab (EPL) on the staff’s experience, confidence, and communication skills. Method: Key leadership and educator team members collaborated on the in-situ simulation set up. Coordination with Simulation Center and Central Supply Department was completed to arrange for delivery of high-fidelity manikins and training crash cart to the site. A team of physicians and nurse educators created CCL and EPL scenarios for the simulations and wrote a simulation evaluation survey for CCL and EPL nurses and technologists who attended. Results: . Simulations were run by both critical care anesthesiologist and clinical nurse educator. Pre-simulation and post-simulation surveys were collected immediately prior to and after the in-situ simulation. 38 staff completed pre and post surveys. Pre-simulation, 50.00% of staff strongly agreed that they were confident in their ability to care for a decompensated patient based on the prior CC-ART training versus, post-simulation, 84.21% strongly agreed. Pre-simulation, 26.32% strongly agreed that the simulation center training was similar to their actual work experience versus post-simulation, 78.95% agreed the in-situ simulation matched their actual work experience. Pre-simulation, 52.63% strongly agreed that they were confident in their ability to communicate their needs during emergencies or code blue situations versus post-simulation 86.84% agreed. Conclusion: This quality improvement project highlights the effectiveness of in situ resuscitation simulation in improving healthcare professionals' confidence, training realism, and communication skills . Analysis of patient outcomes is needed to determine the effectiveness and duration of impact of in situ training for clinical practice.

Utilization of Shock Team and Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) in the Management of Cardiogenic Shock in Northern Ontario

BackgroundDespite advancements in critical care and coronary revascularization, cardiogenic shock (CS) outcomes remain poor. Implementing a shock team and use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) have been associated with improved CS outcomes, but its feasibility in remote and rural areas remains unknown. MethodsThis retrospective study included patients with CS who required mechanical circulatory support (MCS) at Health Sciences North, Sudbury, Ontario. The analysis aimed to accomplish 2 objectives: first, to review the outcomes associated with use of Impella (Abiomed, Danvers, MA) and, second, to assess the feasibility of establishing a shock team to facilitate the local implementation of VA-ECMO. The primary endpoint was in-hospital mortality. ResultsThe outcomes of 15 patients with CS who received Impella between 2015 and 2021 were reviewed. Their average age was 65 years (standard deviation [SD]: 13), and 8 patients (53%) were female. CS was ischemic in 12 patients (80%). Transfemoral Impella CP (cardiac power) was the most frequently used (93%). Thirteen patients (87%) died during the index hospital stay post-Impella because of progressive circulatory failure. The shock team was established following consultations with several Canadian MCS centres, leading to the development of a protocol to guide use of MCS. There have been 4 cases in which percutaneous VA-ECMO using Cardiohelp (Getinge/Maquet, Wayne, NJ) has been used; 3 (75%) survived beyond the index hospitalization. ConclusionsThis analysis demonstrated the feasibility of implementing a shock team in remote Northern Ontario, enabling the use of VA-ECMO with success in a centre with a sizeable rural catchment area. This initiative helps address the gap in cardiac care outcomes between rural and urban areas in Ontario.

Changes in short-term (in-ICU and in-hospital) mortality following Intensive Care Unit admission in adults Living with HIV: 2000-2019.

Limited data suggest intensive care unit (ICU) outcomes have improved in people with HIV (PWH). We describe trends in in-ICU/in-hospital mortality among PWH following admission to ICU in a single UK-based HIV referral centre, from 1 January 2000 to 31 December 2019. Modelling of associations between ICU admission and calendar year of admission was done using logistic regression with adjustment for age, sex, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, CD4+ T-cell count and diagnosis of HIV at/within the past 3 months. Among 221 PWH (71% male, median [interquartile range (IQR)] age 45 years [38-53]) admitted to ICU, median [IQR] APACHE II score and CD4+ T-cell count were 19 [14-25] and 122 cells/mm3 [30-297], respectively; HIV-1 viral load was ≤50 copies/ml in 46%. The most common ICU admission diagnosis was lower respiratory tract infection (30%).In-ICU and in-hospital, mortality were 29% and 38.5%, respectively. The odds of in-ICU mortality decreased over the 20-year period by 11% per year [odds ratio (OR): 0.89 (95% confidence interval (CI): 0.84-0.94)] with in-hospital mortality decreasing by 14% per year [0.86 (0.82-0.91)]. After adjusting for patient demographics and clinical factors, both estimates were attenuated, however, the odds of in-hospital mortality continued to decline over time [in-ICU mortality: adjusted OR: 0.97 (0.90-1.05); in-hospital mortality: 0.90 (0.84-0.97)]. Short-term mortality of critically ill PWH admitted to ICU has continued to decline in the ART era. This may result from changing indications for ICU admission, advances in critical care and improvements in HIV-related immune status.

Ventilator-associated pneumonia

Ventilator-associated pneumonia (VAP) has traditionally been defined as pneumonia in patients with mechanical ventilation for at least 48 h. Despite advancements in critical care, VAP remains to be a complication resulting in huge financial burden to patients. The limitations to the criteria have resulted in an urge to redefine VAP by the Centers for Disease Control and Prevention. Ventilator-associated event (VAE) has been well categorized in adult population; however, in pediatric cohort, while surveillance enhances the detection of infectious and noninfectious complications which can influence patient outcomes, there are many gaps in its classification and management. Establishing a diagnosis of VAP/VAE is crucial in management of a critically ill patient. The role of clinical criteria in concordance with laboratory evidence of inflammatory markers along with chest X-ray helps in supplementing the diagnosis. The presence of culture positivity aids in diagnosis with minimally invasive bronchoalveolar lavage providing a reasonable and safe method. Early empiric antibiotic treatment in suspected patients is beneficial. The role of antibiotic stewardship will help in prevention of antimicrobial resistance in treatment of VAP. More emphasis on VAP prevention measures with multidisciplinary approach is the way forward in overcoming this morbid condition in the intensive care units.

Role of Pellino-1 in Inflammation and Cardioprotection following Severe Sepsis: A Novel Mechanism in a Murine Severe Sepsis Model †.

Intra-abdominal sepsis is commonly diagnosed in the surgical population and remains the second most common cause of sepsis overall. Sepsis-related mortality remains a significant burden in the intensive care unit despite advances in critical care. Nearly a quarter of the deaths in people with heart failure are caused by sepsis. We have observed that overexpression of mammalian Pellino-1 (Peli1), an E3 ubiquitin ligase, causes inhibition of apoptosis, oxidative stress, and preservation of cardiac function in a myocardial infarction model. Given these manifold applications, we investigated the role of Peli1 in sepsis using transgenic and knockout mouse models specific to this protein. Therefore, we aimed to explore further the myocardial dysfunction seen in sepsis through its relation to the Peli 1 protein by using the loss of function and gain-of-function strategy. A series of genetic animals were created to understand the role of Peli1 in sepsis and the preservation of heart function. Wild-type, global Peli1 knock out (Peli1-/-), cardiomyocyte-specific Peli1 deletion (CP1KO), and cardiomyocyte-specific Peli1 overexpressing (alpha MHC (αMHC) Peli1; AMPEL1Tg/+) animals were divided into sham and cecal ligation and puncture (CLP) surgical procedure groups. Cardiac function was determined by two-dimensional echocardiography pre-surgery and at 6- and 24-h post-surgery. Serum IL-6 and TNF-alpha levels (ELISA) (6 h), cardiac apoptosis (TUNEL assay), and Bax expression (24 h) post-surgery were measured. Results are expressed as mean ± S.E.M. AMPEL1Tg/+ prevents sepsis-induced cardiac dysfunction assessed by echocardiographic analysis, whereas global and cardiomyocyte-specific deletion of Peli1 shows significant deterioration of cardiac functions. Cardiac function was similar across the sham groups in all three genetically modified mice. ELISA assay displayed how Peli 1 overexpression decreased cardo-suppressive circulating inflammatory cytokines (TNF-alpha, IL-6) compared to both the knockout groups. The proportion of TUNEL-positive cells varied according to Peli1 expression, with overexpression (AMPEL1Tg/+) leading to a significant reduction and Peli1 gene knockout (Peli1-/- and CP1KO) leading to a significant increase in their presence. A similar trend was also observed with Bax protein expression. The improved cellular survival associated with Peli1 overexpression was again shown with the reduction of oxidative stress marker 4-Hydroxy-2-Nonenal (4-HNE). Our results indicate that overexpression of Peli1 is a novel approach that not only preserved cardiac function but reduced inflammatory markers and apoptosis following severe sepsis in a murine genetic model.

537 Epidemiology of Elderly Burn Injuries – A Five Decade Single Center Retrospective Review

Abstract Introduction Age has long been known to be an independent risk factor for worse outcomes in burn patients. In comparison to younger patients, geriatric patients have higher morbidity and mortality. As the median age of the US population has increased, we have seen a greater proportion of elderly burn patients at our burn unit over the last five decades. Methods Retrospective chart review was performed for all burn patients admitted to our burn unit between 2000 and 2019. Demographics and outcomes data was collected for geriatric patients (age 65 and older). This was compared to historic data available for our burn unit between 1972 to 2000. Results Between 2000 to 2019, our burn unit admitted a total of 5881 burn patients of all ages. There were 652 (11%) geriatric patients admitted. The proportion of geriatric patients admitted statistically significantly increased over that period. Meanwhile, length of stay and mortality statistically significantly decreased in the 2000-2019 time period compared to the previous period. The main mechanism of burn injury was flame exposure. Compared to data on geriatric burn patients from 1972 to 2000, mortality has decreased substantially. In the 1970s mortality was 77% compared to 21% in the past decade. The mortality rate increased significantly with age, TBSA and inhalation injury over both time periods. Conclusions Though lagging behind younger age groups, overall survival and outcomes are improving in elderly burn patient due to advances in critical care and surgical burn management. Acknowledging the unique characteristics of this group of patients, such as impaired healing and multiple comorbidities, allows for improved outcomes. Applicability of Research to Practice Burn centers should notice and prepare for an increasing trend in elderly burn patient admission.

Delayed treatment can lead to significant morbidity and sometimes mortality. Current published claims analyses reflect data up to 2011. Given a rapidly aging population and advances in critical care, we sought to examine characteristics and outcomes of patients with sepsis secondary to obstructing stones in a contemporary cohort, with a focus on outcomes in older adults. METHODS: We conducted a retrospective cohort study using data from the nationwide Premier Healthcare claims database (2016-2020) to identify hospital inpatients aged 18-95 treated for septic urolithiasis, using ICD-10 diagnostic codes consistent with sepsis with urinary stones. Baseline sociodemographic factors were described and stratified into 2 age groups: adults 65 years and older defined as “older adults”, and adults aged <65 years defined as the “younger cohort”. Outcomes such as length of stay, mortality, and discharge disposition were also compared in the 2 groups. RESULTS: The study cohort included 27,976 patients, of which 15,304 (54.7%) were older adults (Table 1). The average age of older adults was 76.0 (SD ±11.6) years, compared with 49.8 (SD ±7.3) years in younger cohort (p<0.001). Among older adults, 46.4% were male, versus 35.9% in the younger cohort; overall the cohort was predominantly non-Hispanic white (76.6%). Older adults were less likely to be cared for in teaching hospitals (p<0.001), and more likely to be cared for in smaller hospitals (<500 beds, p<0.001). Despite receiving more aggressive care (invasive mechanical ventilation, vasopressor use) and incurring higher costs (p<0.001), older adults experienced substantially higher mortality (RR 2.35, 95% confidence interval 2.1-2.7, p<0.001). In addition, older adults were significantly more likely to be discharged to a skilled nursing facility (31.8%) than younger adults (13.4%). CONCLUSIONS: Older adults hospitalized with septic stones have significantly worse outcomes, receive more aggressive care, and incur higher healthcare costs. Additional investigation is needed to identify patient, clinician, and facility-level drivers of these outcomes, so as to create pathways to reduce disparities and optimize outcomes for older adults.

Recent advances in critical care.

Recent advances in critical care.

Recent advances in critical care: Part II.

With the increasing number of critically ill patients being admitted to intensive care units (ICUs), newer techniques and treatment modalities continue to evolve for their adequate management. Thus, it has become imperative to understand existing tools and resources, and utilise or repurpose them to achieve better results that can decrease morbidity and mortality. In this writeup, we chose five areas of interest, including analgosedation, role of colloids, recent advancements in the management of respiratory failure, the role of extracorporeal membrane oxygenation, and newer antimicrobials. The role of analgosedation in the critically ill has gained importance with focus on post-ICU syndromes, and albumin has re-entered the fray as a possible repairer of the injured glycocalyx. The coronavirus disease 2019 (COVID-19) pandemic forced us to relook at various ventilator strategies and mechanical support for the failing circulation has now become more common with clear end-points. Rising microbial antibiotic resistance has opened up the research on newer antibiotics.

Recent advancements in critical care: Part I.

Medical colleges are now developing or refurbishing their anaesthesia intensive care units. In most teaching colleges, the residency post includes working in the critical care unit (CCU). Critical care is a rapidly evolving and popular super-speciality for postgraduate students. In some hospitals, anaesthesiologists play a key role in the management of the CCU. As perioperative physicians, all anaesthesiologists should be aware of the recent advancements in diagnostic and monitoring gadgets and investigations in critical care so that they may manage perioperative events effectively. Haemodynamic monitoring gives us warning signs about the change in the internal milieu of the patient. Point-of-care ultrasonography helps in rapid differential diagnosis. Point-of-care diagnostics give us instant bed-side information on the condition of a patient. Biomarkers help in confirming diagnosis, in monitoring, treatment, and providing prognosis. Molecular diagnostics guide anaesthesiologists in providing specific treatment to a causative agent. This article touches upon all of these management strategies in critical care and attempts to put forth the recent advancements in this speciality.

Mitigating Burnout in a Team of Pediatric Cardiac Critical Care Advanced Practice Providers: A Team-Building Intervention

This quality improvement project used data from individual conversations and group development theory to implement a team-building intervention to mitigate burnout and improve team climate in a group of advanced practice providers. Two validated questionnaires were used to measure the impact of a team-building workshop and the drafting of a team agreement. Results demonstrated significant improvement in team burnout scores immediately post-intervention; however, improvement was not sustained. Anecdotally, the team agreement has successfully improved conflict resolution among group members.
