Endothelial cells line the inner portion of the heart, blood vessels, and lymphatic vessels; a basal membrane of extracellular matrix lines the extraluminal side of endothelial cells. The apical side ...of endothelial cells is the site for the glycocalyx, which is a complex network of macromolecules, including cell-bound proteoglycans and sialoproteins. Sepsis-associated alterations of this structure may compromise endothelial permeability with associated interstitial fluid shift and generalized edema. Indeed, in sepsis, the glycocalyx acts as a target for inflammatory mediators and leukocytes, and its ubiquitous nature explains the damage of tissues that occurs distant from the original site of infection. Inflammatory-mediated injury to glycocalyx can be responsible for a number of specific clinical effects of sepsis, including acute kidney injury, respiratory failure, and hepatic dysfunction. Moreover, some markers of glycocalyx degradation, such as circulating levels of syndecan or selectins, may be used as markers of endothelial dysfunction and sepsis severity. Although a great deal of experimental evidence shows that alteration of glycocalyx is widely involved in endothelial damage caused by sepsis, therapeutic strategies aiming at preserving its integrity did not significantly improve the outcome of these patients.
An accurate assessment of preoperative risk may improve use of hospital resources and reduce morbidity and mortality in high-risk surgical patients. This study aims at implementing an automated ...surgical risk calculator based on Artificial Neural Network technology to identify patients at risk for postoperative complications. We developed the new SUMPOT based on risk factors previously used in other scoring systems and tested it in a cohort of 560 surgical patients undergoing elective or emergency procedures and subsequently admitted to intensive care units, high-dependency units or standard wards. The whole dataset was divided into a training set, to train the predictive model, and a testing set, to assess generalization performance. The effectiveness of the Artificial Neural Network is a measure of the accuracy in detecting those patients who will develop postoperative complications. A total of 560 surgical patients entered the analysis. Among them, 77 patients (13.7%) suffered from one or more postoperative complications (PoCs), while 483 patients (86.3%) did not. The trained Artificial Neural Network returned an average classification accuracy of 90% in the testing set. Specifically, classification accuracy was 90.2% in the control group (46 patients out of 51 were correctly classified) and 88.9% in the PoC group (8 patients out of 9 were correctly classified). The Artificial Neural Network showed good performance in predicting presence/absence of postoperative complications, suggesting its potential value for perioperative management of surgical patients. Further clinical studies are required to confirm its applicability in routine clinical practice.
Continuous veno-venous hemodialysis with high cut-off membranes (HCO-CVVHD) removes inflammatory mediators involved in organ dysfunction during sepsis. The aim of the present study was to assess the ...variations in SOFA score and identify early predictors of short-term mortality in a cohort of patients with septic shock, treated with HCO-CVVHD for acute kidney injury (AKI).
An observational prospective multicenter cohort study was conducted in four mixed medical-surgical ICUs. Thirty-eight patients with septic shock and AKI (KDIGO stage≥1) treated with HCO-CVVHD have been included in this study. Patients were divided into Survivors and non-Survivors according to mortality observed at 72nd hr of treatment. The variation of SOFA scores and clinical/biochemical parameters were described over time for the entire population and specifically for Survivors and non-Survivors. Similarly, circulating inflammatory mediators (as IL-6, TNF-a and IL-10) were described over time. A logistic regression analysis was used to identify the baseline clinical and biochemical parameters associated with 72 hrs-ICU mortality.
Overall, the mean SOFA score was 12±3 at baseline, 10.9±3 at 6hrs, 9.8±3 at 12hrs, 8.9±3.3 at 24 hrs, and 8±3.5 at 48 hrs after HCO-CVVHD initiation; and 6.5±2.7 at 24 hrs and 6.6±3 at 48 hrs after HCO-CVVHD discontinuation. In the multivariate regression analysis, baseline serum lactate levels and AKI stage independently correlated with short-term mortality during HCO-CVVHD. A significant reduction was observed in circulating levels of TNFα and IL-6 among Survivors.
SOFA score significantly decreased early after initiation of HCO-CVVHD in patients with septic AKI. Baseline lactate levels and the AKI stage resulted to be associated to 72 hrs-ICU-mortality.
Adult and pediatric palliative care (PC) share common aims and ethical principles but differ in many organizational and practical aspects. The aim of this narrative review is to analyze these ...differences and focus on which key aspects of pediatric palliative care could integrate adult services for a better care of suffering patients.Interventions which are peculiar of pediatric PC respect to adult PC include: an earlier referral to the PC service to identify the needs and plan the interventions at an earlier stage of the disease; consequently, a more systematic cooperation with the disease-specific physicians to reduce the burden of treatments; a better integration with the community and the social surroundings of the patients, to prevent social isolation and preserve their social role; a more dynamic organization of the PC services, to give patients the chance of being stabilized at in-hospital or residential settings and subsequently discharged and cared at home whenever possible and desired; the implementation of respite care for adults, to help the families coping with the burden of the disease of their beloved and promote the home-based PC.This review underlines the relevance of some key-aspects of pediatric PC that can be beneficial also within PC of adults. Its findings give the chance for a more dynamic and modern organization of adult PC services and may serve as a basis of future research for new interventions.
A maladaptive response to surgical stress might lead to postoperative complications. A multidisciplinary approach aimed at controlling the surgical stress response may reduce procedural complications ...and improve patients' quality of life in the short and long term. Several studies suggest that psychological interventions may interact with the pathophysiology of surgical stress response, potentially influencing wound repair, innate and adaptive immunity, inflammation, perception of pain, and patients' mood. The aim of this systematic review is to summarise the effects of perioperative psychological interventions on surgical pain and/or anxiety in adult patients scheduled for elective general abdominal and/or urologic surgery. We conducted a systematic review of controlled clinical trials and observational studies involving psychological interventions for adult patients scheduled for elective general abdominal and/or urologic surgery. Only studies reporting pain and/or anxiety among outcome measures were included in the systematic review. The following psychological interventions were considered: (1) relaxation techniques, (2) cognitive-behavioural therapies, (3) mindfulness, (4) narrative medicine, (5) hypnosis and (6) coping strategies. We examined 2174 papers. Among these, 9 studies were considered eligible for inclusion in this systematic review (1126 patients cumulatively): 8 are randomised controlled trials and 1 is an observational prospective pre/post study. Psychological characteristics widely influence the pathophysiological mechanisms underlying the neuroendocrine and inflammatory response to surgical stress, potentially interfering with surgical outcomes. Psychological interventions are technically feasible and realistically applicable perioperatively during abdominal and/or urologic surgery; they influence the pathophysiological mechanisms underlying maladaptive surgical stress response and might have positive effects on patients' surgical outcomes, such as pain and anxiety.

Worldwide, the widespread use of extracorporeal blood purification therapies (EBPTs) is progressively increasing in everyday clinical practice, particularly in critical care settings. The efficacy of ...EBPTs on removal of inflammatory mediators is already well established in the literature. Nonetheless, clinical research is particularly cumbersome in this setting, and many clinical trials aiming at exploring the effect of EBPTs on outcomes have failed in demonstrating consistent results regarding 28-day- or hospital-mortality rates. In recent years, data emerging from large registries have been increasingly used to provide real-world evidence on the effectiveness, quality, and safety of EBPTs. The philosophy behind this Italian Registry is a renewal of the concept of "clinical research" in the field of EBPTs applied to critically ill, septic patients with or without acute kidney injury. The platform used for the registry - specifically designed for research purposes and fed by clinical data prospectively observed - promotes good practice with a positive and active interaction with the physician/researcher. This interaction has favorable real-time effects for the specific patient, providing " bed-side clinical feedbacks ," similarly to the decision support system. Examples of these issues are bundles reminders, suggestions for drug adjustment according to the extracorporeal clearance, clinical calculator for body mass index, or mechanical ventilation setting. The platform-physician interaction has additional useful effects on the single utilizing center, providing " mid-term, center-specific clinical feedbacks ." These generally consist of clusters of data taken over a certain period, for example, regarding patients' outcome, microbiological data, or use of disposable for EBPTs.
Abstract Purpose Acute kidney injury (AKI) is a frequent complication in high-risk patients undergoing major surgery and is associated with longer hospital stay, increased risk for nosocomial ...infection and significantly higher costs. Materials and Methods A prospective observational study exploring the incidence of AKI (AKIN classification at any stage) in high-risk patients within 48-hr. after major abdominal surgery was conducted. Patients' preoperative characteristics, intraoperative management and outcome were evaluated for associations with AKI using a logistic regression model. Results Data from 258 patients were analysed. Thirty-one patients (12%) developed AKI, reaching the AKIN stage 1. No patient reached an AKIN stage higher than 1. AKI patients were older (75.2 vs. 70.2 years; P = 0.0113) and had a higher body mass index (26.5 vs. 25.1 Kg/m2 ). In addition, AKI patients had a significantly longer ICU length of stay (3.4 vs. 2.4 days; P = 0.0017). Creatinine levels of AKI patients increased significantly compared to the preoperative levels at 24 (P = 0.0486), 48 (P = 0.0011) and 72-hr. (P = 0.0055), while after 72-hr. it showed a downwards trend. At ICU discharge, 28 out of 31 patients (90.3%) recovered preoperative levels. Multivariate analysis identified age (OR 1.088; P = 0.002) and BMI (OR 1.124; P = 0.022) as risk factors for AKI development. Moreover, AKI development was an independent risk factor for ICU stays longer than 48-hr. (OR 2.561; P = 0.019). Conclusions Mild AKI is a not rare complication in high-risk patients undergoing major abdominal surgery. Although in almost the totality of cases, the indicators of renal function recovered to preoperative levels, post-operative AKI represents a primary risk factor for a prolonged ICU stay.
Palliative care, with its focus on comprehensive patient assessment encompassing physical, social, emotional, and spiritual pain, plays a crucial role in modern medicine. Despite its significance, ...integration with oncology and other healthcare specialties often occurs late in the disease trajectory. Strategies to bridge this gap include considering a “rebranding” of palliative care to “supportive care.” Early initiation of palliative care, although challenging to define precisely, aims to improve the quality of life for patients and their families. Studies show some benefits, but the evidence remains limited. An embedded model that encourages interdisciplinary collaboration between oncologists and palliative care practitioners has shown promise. However, it raises questions about training and availability of palliative care specialists. A broader approach involves integrating palliative care principles into medical and nursing education to ensure early recognition of patient needs and empathetic communication. Regular monitoring of patients’ physical and non-physical needs, along with appropriate interventions, can alleviate suffering and improve patient outcomes. Ultimately, the integration of palliative care into oncology and other disciplines focuses on addressing the individual’s needs and understanding their unique experience of suffering.
Baclofen withdrawal syndrome represents a clinical emergency that can lead to life-threatening complications. It is often a diagnostic challenge because of its nonspecific nature of presentation and ...degree of symptom overlap with other clinical diseases. Electroencephalography (EEG) might provide important supporting evidence when neurological complications are involved. We present the case of a 55-year-old woman with sudden onset of motor manifestations at the limbs and an altered mental status 24 hours after cessation of intrathecal baclofen administration, following the removal of the pump due to infection, in whom a computed tomography did not show any acute-onset brain injuries, and multiple EEG recordings were performed. The first EEG showed the presence of bilateral sharply contoured waves, in the absence of epileptic discharges and seizures. No correlation between motor manifestations and EEG changes were detected. This EEG pattern was considered to be the expression of an overexcitation of the central nervous system (CNS) due to the loss of baclofen inhibitory effects, excluding an epileptic origin of motor manifestations. Another EEG, performed 24 hours later, showed the presence of triphasic waves with severe generalised slowing, suggesting the presence of encephalopathy. The last EEG, performed 48 hours after the previous recording, when a recovered state of consciousness was already present, showed regression of the triphasic waves and a reorganisation of the background activity. In our case, repeated EEG evaluation allowed monitoring the evolution of acute encephalopathy developed during baclofen withdrawal syndrome, from the initial phase of CNS hyperexcitability, through the phase of metabolic encephalopathy, and to its resolution. This modality allowed for optimising the diagnostic-therapeutic management of the patient during her stay in the intensive care unit.
