ABSTRACT
Background and Objectives: Spiritual care is an essential component of care for the terminally ill, because of its potential to positively impact patient perception of quality of life and dignity. However, it continues to be the least cultivated or even most overlooked aspect of palliative care and end of life. We performed a methodological review using bibliometric analysis to provide a holistic view of the scientific output published on this topic in the literature at the same time outlining present perspectives and research trends. Methods: In accordance with the BIBLIO checklist for reporting the bibliometric reviews of the biomedical literature, pertinent articles were retrieved from the Web of Science (WOS) database. The search string included "spiritual care," "end of life," and their synonyms. The VOSviewer (version 1.6.17) software was used to conduct comprehensive analyses. Semantic and research networks, bibliographic coupling, and journal analysis were examined. Results: A total of 924 articles were identified in WOS, and 842 were retrieved. An increasing trend in the number of publications is observed from 1981 to date, with a peak in the 2019-2021 timeframe. Most articles focused on palliative care, spirituality, spiritual care, religion, end of life, and cancer. The Journal of Pain and Symptom Management contributed the highest number of published documents, while the Journal of Palliative Medicine was the top-cited journal. The highest number of publications originated from collaborations of authors from the United Kingdom, the United States, and Australia. Conclusion: The remarkable increase in the number of publications on spiritual care observed in the years of the COVID-19 pandemic likely reflected global concerns, reasserting the importance of prioritizing spiritual care for whole-person palliation. Spiritual care is integrated with palliative care, in line with the latter's holistic nature and the recognition of spirituality as a fundamental aspect of end-of-life care. Nurses and chaplains exhibited more involvement in palliative-spiritual care than physicians reflecting the belief that chaplains are perceived as specialized providers, and nurses, owing to their direct exposure to spiritual suffering and ethos, are deemed suitable for providing spiritual care.
ABSTRACT
ABSTRACT: Protamine, first isolated from salmon fish sperm and now produced through recombinant biotechnology, is an antidote that neutralizes the anticoagulant properties of heparin. Protamine function is based on the capacity to dissociate the heparin-antithrombin III (AT III) complex (an important link that promotes blood fluidification by inhibiting coagulation), forming the inactive heparin-protamine complex. Protamine has itself dose-dependent anticoagulant properties: It interferes with coagulation factors and platelet function; it stimulates fibrinolysis; it can lead to thrombocytopenia and reduction in thrombin-related platelet aggregation; it decreases platelet response to thrombin receptor agonist in a dose-dependent manner. In this review, we will focus on protamine and its interaction with heparin. Notably, protamine is able to antagonize not only unfractionated heparin (UFH) but also low molecular weight heparins to various degrees. Protamine-allergic and anaphylactoid systemic reactions may affect up to 1 in 10 people and should be prevented and treated early.

OBJECTIVES: Norepinephrine is available commercially in solution containing its salt (eg, tartrate), but only the base form (ie, norepinephrine base) is active pharmacologically. Unfortunately, the outer label of drug packages frequently reports the dosage of norepinephrine as a salt, which can lead potentially to therapeutic errors when prescribing norepinephrine. We performed a survey to assess the level of awareness of this issue. DESIGN: National survey. SETTING: Acute care units of Italian hospitals. PARTICIPANTS: Acute care physicians and nurses. INTERVENTIONS: A 15-item online survey was emailed to 305 critical care practitioners in Italy. Questions included information on the participants' background, methods of diluting norepinephrine, interpretation of recommended doses from guidelines, and a sample case related to the preparation and administration of the drug. MEASUREMENTS AND MAIN RESULTS: We collected 106 responses from 54 hospitals. All hospitals used norepinephrine bitartrate salt. Of the participants, 53% responded that the guidelines express norepinephrine dosages as a salt, 23% as the base form, and 24% were unsure or unaware about it. The simulated patient-dose calculation was resolved in 81% of cases with an incorrect calculation referring to the norepinephrine salt and only in 19% referring to the norepinephrine base. CONCLUSIONS: There is significant variability in dosage management of norepinephrine across different hospital units, as well as a lack of knowledge regarding the salt-to-base ratio. Scientific publications (eg, guidelines) should specify whether they are referring to the base or salt form of norepinephrine. The adoption of different labeling and national standards for dilution may decrease the risk of therapeutic errors.
ABSTRACT
Anesthetic management of pediatric patients poses several challenges and the optimal anesthetic agent for use in this population is still a matter of debate. We systematically searched PubMed/MEDLINE and Google Scholar from their inception for studies that investigated the role and potential applications of remimazolam, a novel ultra-short-acting benzodiazepine, in pediatric patients. Furthermore, in March 2024, an update of the literature search along with an additional post-hoc search on the EMBASE database were performed. A total of fourteen pertinent studies which spanned the 2021-2023 period explored remimazolam as either the primary or adjuvant hypnotic agent for inducing and/or maintaining general anesthesia or sedation. Preliminary evidence derived from these studies highlighted that remimazolam is a safe and effective option for both sedation and general anesthesia in pediatric patients, particularly those with concurrent mitochondrial disorders, myopathic diseases, or at risk for malignant hyperthermia. Moreover, the current evidence suggested that remimazolam may contribute to reducing preoperative anxiety and postoperative delirium in children. Its favorable pharmacodynamic and pharmacokinetic profile demonstrated potential safety, effectiveness, and ease-of-use in various perioperative pediatric contexts, making it suitable for integration into specific protocols, such as intraoperative monitoring of evoked potentials and management of difficult intubation. Notwithstanding these promising findings, further research is essential to determine optimal dosages, establish conclusive evidence of its superiority over other benzodiazepines, and elucidate the impact of genetic factors on drug metabolism.
ABSTRACT
Blood pressure is a critical physiological parameter, particularly in the context of cardiac intensive care and perioperative settings. As a primary indicator of organ perfusion, the maintenance of adequate blood pressure is imperative for the assurance of sufficient tissue oxygen delivery. Among critically ill and major surgery patients, the continuous monitoring of blood pressure is performed as a standard practice for patients. Nonetheless, uncertainties remain regarding blood pressure goals, and there is no consensus regarding blood pressure targets. This review describes the determinants of blood pressure, examine the influence of blood pressure on organ perfusion, and synthesize the current clinical evidence from various intensive care and perioperative settings to provide a concise guidance for daily clinical practice.

AIMS: Artificial intelligence (AI) has emerged as a potential useful tool to support clinical treatment of heart failure, including the setting of mechanical circulatory support (MCS). Modern Impella pumps are equipped with advanced technology (SmartAssist), enabling real-time acquisition and display of data related to both pump performance and the patient's haemodynamic status. These data emerge as an 'ideal' source for data-driven AI applications to predict the clinical course of an ongoing therapeutic protocol. Yet, no evidence of effective application of AI tools in the setting of Impella support is available. On this background, we aimed at identifying possible future applications of AI-based tools in the setting of temporary MCS with an Impella device. METHODS: We explored the state of research and development at the intersection of AI and Impella support and derived future potential applications of AI in routine Impella clinical management. RESULTS: We identified different areas where the future implementation of AI tools may contribute to addressing important clinical challenges in the setting of Impella support, including (i) early identification of the best suited pathway of care according to patients' conditions at presentation and intention to treat, (ii) prediction of therapy outcomes according to different possible therapeutic actions, (iii) optimization of device implantation procedures and evaluation of proper pump position over the whole course of support and (iv) prevention and/or rationale management of haemocompatibility-related adverse events. For each of those areas, we discuss the potential advantages, challenges and implications of harnessing AI-driven insights in the setting of MCS with an Impella device. CONCLUSIONS: Temporary MCS with an Impella device has great potential to benefit from the integration of AI-based tools. Such tools may indeed translate into groundbreaking innovation supporting clinical decision-making and therapy regulation, in particular in complex scenarios such as the multidevice MCS strategy.
ABSTRACT
INTRODUCTION: Remimazolam, an ultra-short-acting benzodiazepine recognized and approved as an anesthetic and sedative in multiple countries, offers a distinctive pharmacokinetic profile, boasting advantages such as rapid onset, short action duration, and rapid recovery. These attributes may contribute to enhanced hemodynamic stability and a diminished risk of respiratory depression compared to other sedatives. EVIDENCE ACQUISITION: We conducted the first comprehensive systematically structured narrative review to evaluate the role and potential application of remimazolam in cardiac surgery. Twenty-one studies published from 2021 to 2023 delved into remimazolam's application in open cardiac surgery, cardiac catheterization or electrophysiology laboratories, and high-risk cardiovascular patients undergoing non-cardiac surgery. EVIDENCE SYNTHESIS: Overall, remimazolam usage was apparently linked to potentially superior hemodynamic stability compared to other hypnotic drugs. However, findings regarding the reduction in postoperative delirium incidence with remimazolam and the doses of remimazolam for anesthesia induction and maintenance were inconsistent across the studies. CONCLUSIONS: Though remimazolam has demonstrated potential safety, efficacy, and ease-of-use for both anesthesia induction and maintenance in cardiac surgery patients and high-risk cardiovascular patients undergoing non-cardiac surgery, further research is imperative to delve into specific patient subgroups (e.g., the elderly or emergent procedures) so as to ascertain optimal dose ranges to suit diverse clinical scenarios.

With the general population aging, both life expectancy and the number of left ventricular assist device (LVAD) implantations in elderly patients are growing. Nevertheless, their perceived long-term quality of life, including psychological aspects, coupled with the respective caregiver's burden, remain under-reported. In light of the rising number of octogenarians with LVAD who necessitate broader healthcare provider involvement, we assessed the long-term quality of life, as defined by both the 36-item short-form health (SF-36) survey and the EuroQol 5 dimensions, 5-level questionnaire (EQ-5D-5L)-including the visual analog scale-in octogenarian LVAD patients who had received treatment at our institution. Additionally, we evaluated the psychological health of octogenarian LVAD patients using the psychological general well-being index (PGWBI), alongside their caregivers' well-being through the 22-item version of the Zarit Burden Interview (ZBI). Of 12 octogenarian LVAD patients, 5 were alive and willing to answer questionnaires. Mean age at implant was 74 ± 2 years. Median follow-up was 2464 (IQR = 2375-2745) days. Although variable, the degree of health and psychological well-being perceived by octogenarian patients with LVAD was "good." Interestingly, the burden of assistance reported by caregivers, though relevant, was greatly varied, suggesting the need to better define and address psychological long-term aspects related to LVAD implantation for both patients and caregivers with a broad-spectrum approach.

INTRODUCTION: Perioperative cardiogenic shock (CS) in cardiac surgery is still burdened by a high mortality risk. The introduction of Impella pumps in the therapeutic armory of temporary mechanical circulatory support (tMCS) has potential implications to improve the management of complex cases, although it has never been systematically addressed. We performed a systematic review of the reported use of tMCS with Impella in cardiac surgery. METHODS: We searched PubMed for all original studies on the Impella use in adult patients in cardiac surgery. RESULTS: Nineteen studies (out of 151 identified by search string) were included. All studies were observational and all but one (95%) were retrospective. Seven studies focused on the implantation of Impella in the pre-operative setting (coronary or valvular surgery), either as a prophylactic device in high-risk cases (3 studies) or in patients with CS as stabilization tool prior to cardiac surgery procedure (4 studies). Three studies reported the use of Impella as periprocedural support for percutaneous valvular procedure, three as bridge to heart replacement, and six for postcardiotomy CS. Impella support had a low complication rate and was successful in supporting hemodynamics pre-, intra- and postoperatively. Most consistently reported data were left-ventricular ejection fraction at implant, short-term survival and weaning rate. CONCLUSIONS: tMCS with Impella in cardiac surgery patients is feasible and successful. It can be applied in selected cardiac surgery patients and presents advantages over other types of support. Systematic prospective studies are needed to standardize indications for implant and management of surgical issues, and to identify which patients may benefit.

Every year, 80,000-100,000 ablation procedures take place in the United States and approximately 1% of these involve paediatric patients. As the paediatric population undergoing catheter ablation to treat dysrhythmia is constantly growing, involvement of anaesthesiologists in the cardiac electrophysiology laboratory is simultaneously increasing. Compared with the adult population, paediatric patients need deeper sedation or general anaesthesia (GA) to guarantee motionlessness and preserve comfort. As a result, the anaesthesiologist working in this setting should keep in mind heart physiopathology as well as possible interactions between anaesthetic drugs and arrhythmia. In fact, drug-induced suppression of accessory pathways (APs) conduction capacity is a major concern for completing a successful electrophysiology study (EPS). Nevertheless, the literature on this topic is scarce and the optimal type of anaesthesia in EPS and ablation procedures in children is still controversial. Thus, the main goal of the present review is to collect the literature published so far on the effects on cardiac conduction tissue of the drugs commonly employed for sedation/GA in the cath lab for EPS and ablation procedures to treat supraventricular tachycardia in patients aged <18 years.

BACKGROUND: Impairment of platelet responses to adenosine diphosphate (ADP) is typified by mild to severe bleeding diathesis, easy bruising, excessive mucosal and post-operative bleeding. Patients lack full platelet activation and aggregation in response to ADP. Following research of the literature in Scopus, PubMed/MEDLINE, ScienceDirect, and the Cochrane Library, we report only 18 patients described to date with impaired platelet response to ADP, none of whom in the high bleeding-risk surgical setting or exploring potential therapeutic options. Data regarding population, putative genetic mutations, modes of inheritance, functional defects, and related clinical manifestations were retrieved from case series and case reports. CASE PRESENTATION: A 40-year-old woman was scheduled for on-pump cardiac surgery. Her past medical history included episodes of spontaneous mucocutaneous hemorrhages of the mild entity since childhood. Multiple electrode aggregometry (MEA, Multiplate® Roche Diagnostics, Rotkreuz, Switzerland) was used to evaluate platelet response to thrombin-activated peptide-6 (TRAP), arachidonic acid (ASPI), and ADP. An inadequate platelet aggregation induced using a high concentration of ADP with normal TRAP and ASPI tests was detected preoperatively. Therefore, intravenous desmopressin (DVVAP) 0.3 µg/kg body weight was administered to manage microvascular bleeding developed after weaning from cardiopulmonary bypass (CPB). CONCLUSIONS: Proper management of impaired platelet response to ADP requires a systematic assessment. The Multiplate analyzer is a valuable tool to promptly detect the disorder when a high clinical suspect is present and obtain insights during high bleeding-risk surgical procedures. DVVAP can be beneficial as first-line therapy in bleeding patients to improve platelet function.
