[PMID: 37484842 PMCID: PMC10359115 DOI: 10.3389/fmed.2023.1177786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 06/15/2023] [Indexed: 07/25/2023] Open
Abstract
Background Providing intensive care is increasingly expensive, and the aim of this study was to construct a risk column line graph (nomograms)for prolonged length of stay (LOS) in the intensive care unit (ICU) for patients with chronic obstructive pulmonary disease (COPD). Methods This study included 4,940 patients, and the data set was randomly divided into training (n = 3,458) and validation (n = 1,482) sets at a 7:3 ratio. First, least absolute shrinkage and selection operator (LASSO) regression analysis was used to optimize variable selection by running a tenfold k-cyclic coordinate descent. Second, a prediction model was constructed using multifactorial logistic regression analysis. Third, the model was validated using receiver operating characteristic (ROC) curves, Hosmer-Lemeshow tests, calibration plots, and decision-curve analysis (DCA), and was further internally validated. Results This study selected 11 predictors: sepsis, renal replacement therapy, cerebrovascular disease, respiratory failure, ventilator associated pneumonia, norepinephrine, bronchodilators, invasive mechanical ventilation, electrolytes disorders, Glasgow Coma Scale score and body temperature. The models constructed using these 11 predictors indicated good predictive power, with the areas under the ROC curves being 0.826 (95%CI, 0.809-0.842) and 0.827 (95%CI, 0.802-0.853) in the training and validation sets, respectively. The Hosmer-Lemeshow test indicated a strong agreement between the predicted and observed probabilities in the training (χ2 = 8.21, p = 0.413) and validation (χ2 = 0.64, p = 0.999) sets. In addition, decision-curve analysis suggested that the model had good clinical validity. Conclusion This study has constructed and validated original and dynamic nomograms for prolonged ICU stay in patients with COPD using 11 easily collected parameters. These nomograms can provide useful guidance to medical and nursing practitioners in ICUs and help reduce the disease and economic burdens on patients.

Abstract
Traumatic brain injury (TBI) is common and potentially devastating. Traditional examination-based patient monitoring following TBI may be inadequate for frontline clinicians to reduce secondary brain injury through individualized therapy. Multimodal neurologic monitoring (MMM) offers great potential for detecting early injury and improving outcomes. By assessing cerebral oxygenation, autoregulation and metabolism, clinicians may be able to understand neurophysiology during acute brain injury, and offer therapies better suited to each patient and each stage of injury. Hence, we offer this primer on brain tissue oxygen monitoring, pressure reactivity index monitoring and cerebral microdialysis. This narrative review serves as an introductory guide to the latest clinically-relevant evidence regarding key neuromonitoring techniques.

[PMID: 34145947 DOI: 10.1111/nicc.12640] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Revised: 04/11/2021] [Accepted: 04/15/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Fever frequently occurs in patients with traumatic brain injury and can cause secondary damage to the brain. Critical care nurses play essential roles in assessing and managing fever in these patients. AIM The study aimed to (a) examine the fever causes in and condition of neurosurgical patients with traumatic brain injury in intensive care, (b) identify the factors associated with fever, and (c) determine the effects of fever on hospital stay and prognosis. STUDY DESIGN This study is a retrospective observational design. METHODS Data were collected through chart reviews of 93 traumatic brain injury patients admitted to a teaching hospital's intensive care unit for postoperative care. Fever was defined as at least one episode of body temperature >38°C. RESULTS Of the 93 patients, 76 developed a fever within 1-week post-craniotomy. Of these, 49 were infection-related and 27 were unexplained. Results of logistic regression showed that the preoperative Glasgow coma scale score (ß = -.323; P = .013) and length of intubation (ß = .480; P = .005) were the key predictors of unexplained post-craniotomy fever, and these two variables (ß = -.494; P < .001 and ß = .479; P = .006, respectively) were also the key predictors of infection-related fever. CONCLUSION A significant portion of patients developed a fever during the first post-craniotomy week. Patients with a lower pre-craniotomy Glasgow coma scale score and a longer intubation length were at a greater risk for both infection-related fever and unexplained fever. Patients with fever had a bad outcome score. RELEVANCE TO CLINICAL PRACTICE Critical care nurses should closely monitor traumatic brain injury patients' body temperatures and employ evidence-based infection prevention and control measures to minimize their infection risks. Respiratory care and intensive care unit Liberation Bundle should be reinforced to liberate these patients from mechanical ventilation and its associated complications.

Abstract
Worldwide elderly traumatic brain injury (TBI) patients tend to become an increasing burden to the society. Thus, a faster and less expensive way of evaluating TBI victims is needed. In the present study we investigated if optical coherence tomography (OCT) could be used as such a method. By using an animal model, we established if OCT can detect cortical changes in the acute phase of a penetrating TBI, in young (5-7 months) and old (20-22 months) rats. Due to the long-term evolution of TBI's, we wanted to investigate to what extent OCT could detect changes within the cortex in the chronic phase. Adult (7-12 months) male rats were used. Surprisingly, OCT imaging of the normal hemisphere was able to discriminate age-related differences in the mean gray values (MGV) of recorded pixels (p = .032). Furthermore, in the acute phase of TBI, OCT images recorded at 24 hr after the injury showed differences between the apparent damaged area of young and aged animals. Changes of MGV and skewness were only recorded 48 hr after injury. Monitoring the chronical evolution of the TBI with OCT revealed changes over time exceeding the normal range recorded for MGV, skewness and kurtosis, 14 and 21 days after TBI. Although in the present study we still used an extremely invasive approach, as technology improves, less invasive and non-harmful ways of recording OCT may allow for an objective way to detect changes within the brain structure after brain injuries.

Abstract
This review on the mechanisms of neuroinflammation following subarachnoid hemorrhage will focus mainly on toll-like receptor 4 (TLR4), Heme Oxygenase-1 (HO-1), and the role of microglia and macrophages in this process. Vasospasm has long been the focus of research in SAH; however, clinical trials have shown that amelioration of vasospasm does not lead to an improved clinical outcome. This necessitates the need for novel avenues of research. Our work has demonstrated that microglial TLR4 and microglial HO-1, not only affects cognitive dysfunction, but also circadian dysrhythmia in a mouse model of SAH. To attempt to translate these findings, we have also begun investigating macrophages in the cerebrospinal fluid of SAH patients. The goal of this review is to provide an update on the role of TLR4, HO-1, and other signal transduction pathways in SAH-induced neuroinflammation.

Abstract
Fever increases mortality and morbidity and length of stay in neurocritically ill patients. Various methods are used in the neuroscience intensive care unit (NSICU) to control fever. Two such methods involve the Arctic Sun hydrogel wraps and the Gaymar cooling wraps. The purpose of our study was to compare these two methods in neurocritical care patients who had temperature >37.5°C for more than three consecutive hours and that was refractory to standard treatments. Data of patients requiring cooling wraps for treatment of hyperthermia at an NSICU at an academic, tertiary referral center were retrospectively reviewed. The average temperature before cooling was 38.5°C ± 0.38°C and 38.4°C ± 0.99°C for the Gaymar and Arctic Sun groups, respectively (p = 0.89). The Gaymar group took on average 16 ± 21.9 hours to reach goal temperature, whereas the Arctic Sun group took 2.22 ± 1.39 hours (p = 0.08). The average time outside of the target temperature was 57.0 ± 58.0 hours in the Gaymar group compared with 13.7 ± 17.1 hours in the Arctic Sun group (p = 0.04). Average duration of using the cooling wraps was similar between the two groups; 81.8% of patients had rebound hyperthermia in the Gaymar group compared with 20% in the Arctic Sun group (p = 0.0089). The Arctic Sun group had a nonsignificant increased incidence of shivering compared with the Gaymar group (40% vs. 18.18%, p = 0.36). We found that Arctic Sun surface cooling device was more efficient in attaining the target temperature, had less incidence of rebound hyperthermia, and was able to maintain normothermia better than Gaymar cooling wraps. The incidence of shivering tended to be more common in the Arctic Sun group.

Abstract
BACKGROUND Headache after aneurysmal subarachnoid hemorrhage (SAH) is very common and is often described as the "worst headache imaginable." SAH-associated headache can persist for days to weeks and is traditionally treated with narcotics. However, narcotics can have significant adverse effects. We hypothesize that gabapentin (GBP), a non-narcotic neuropathic pain medication, would be safe and tolerable and would reduce narcotic requirements after SAH. METHODS We retrospectively reviewed the clinical, radiographic, and laboratory data of SAH patients at the neuroscience intensive care unit at Mayo Clinic in Jacksonville, Florida, from January 2011 through February 2013. Headache intensity was quantified by a visual analog scale score. Total opioid use per day was tabulated using an intravenous morphine equivalents scale. Cerebrospinal fluid was also reviewed when available. RESULTS There were 53 SAH patients who were treated with GBP along with other analgesics for headache. Among these SAH patients, 34 (64 %) were women, with a mean age of 54 years (SD 12.3). Severe headache was observed in all SAH patients. GBP dosing was rapidly escalated within days of SAH up to a median of 1,200 mg/day, with a range of 300 mg three times a day to 900 mg three times a day. Approximately 6 % of patients treated with GBP had nausea (95 % CI 1-16 %), and only one patient (1.8 %) had to discontinue GBP. CONCLUSIONS GBP appears to be relatively safe and tolerable in SAH patients with headache and may be a useful narcotic-sparing agent to prevent narcotics-associated complications, such as gastrointestinal immobility, ileus, and constipation.

Abstract
Hyperthermia from a central cause is associated with increased morbidity and mortality. Dysfunction of brainstem thermoregulatory pathways may explain the intractable rise in temperature. Antipyretics, dantrolene, bromocriptine, and surface and intravascular cooling devices have been attempted for temperature control. We report the case of a 54-year-old woman with history of hypertension who presented with pontine hemorrhage with extension into the midbrain and medulla. On days 8-9 of her hospital admission, she developed intractable fever and expired the same day despite aggressive treatment of hypothermia, including antipyretics, ice lavage, cold fluid boluses, surface cooling, dantrolene, and bromocriptine. Hyperthermia from brainstem hemorrhage can be difficult to manage with current treatment options. Early recognition of those patients who may develop hyperthermia could lead to early intervention and possibly better outcomes. More evidence from prospective randomized controlled trials will elucidate the risk-benefit profile of achieving normothermia with aggressive fever control in these patients.

Abstract
BACKGROUND Stroke is one of the major diseases with human mortality. Recent clinical research has indicated that early changes in common physiological variables represent a potential therapeutic target, thus the manipulation of these variables may eventually yield an effective way to optimise stroke recovery. AIMS We examined correlations between physiological parameters of patients during the first 48 hours after a stroke, and their stroke outcomes after three months. We wanted to discover physiological determinants that could be used to improve health outcomes by supporting the medical decisions that need to be made early on a patient's stroke experience. METHOD We applied regression-based machine learning techniques to build a prediction algorithm that can forecast threemonth outcomes from initial physiological time series data during the first 48 hours after stroke. In our method, not only did we use statistical characteristics as traditional prediction features, but we also adopted trend patterns of time series data as new key features. RESULTS We tested our prediction method on a real physiological data set of stroke patients. The experiment results revealed an average high precision rate: 90%. We also tested prediction methods only considering statistical characteristics of physiological data, and concluded an average precision rate: 71%. CONCLUSION We demonstrated that using trend pattern features in prediction methods improved the accuracy of stroke outcome prediction. Therefore, trend patterns of physiological time series data have an important role in the early treatment of patients with acute ischaemic stroke.

Abstract
OBJECT The purpose of this study was to evaluate temporal trends in traumatic brain injury (TBI); the impact of hospital volume and surgeon volume on length of stay (LOS), hospitalization cost, and in-hospital mortality rate; and to explore predictors of these outcomes in a nationwide population in Taiwan. METHODS This population-based patient cohort study retrospectively analyzed 16,956 patients who had received surgical treatment for TBI between 1998 and 2009. Bootstrap estimation was used to derive 95% confidence intervals for differences in effect sizes. Hierarchical linear regression models were used to predict outcomes. RESULTS Patients treated in very-high-volume hospitals were more responsive than those treated in low-volume hospitals in terms of LOS (-0.11; 95% CI -0.20 to -0.03) and hospitalization cost (-0.28; 95% CI -0.49 to -0.06). Patients treated by high-volume surgeons were also more responsive than those treated by low-volume surgeons in terms of LOS (-0.19; 95% CI -0.37 to -0.01) and hospitalization cost (-0.43; 95% CI -0.81 to -0.05). The mean LOS was 24.3 days and the average LOS for very-high-volume hospitals and surgeons was 61% and 64% shorter, respectively, than that for low-volume hospitals and surgeons. The mean hospitalization cost was US $7,292.10, and the average hospitalization cost for very-high-volume hospitals and surgeons was 19% and 22% lower, respectively, than that for low-volume hospitals and surgeons. Advanced age, male sex, high Charlson Comorbidity Index score, treatment in a low-volume hospital, and treatment by a low-volume surgeon were significantly associated with adverse outcomes (p < 0.001). CONCLUSIONS The data suggest that annual surgical volume is the key factor in surgical outcomes in patients with TBI. The results improve the understanding of medical resource allocation for this surgical procedure, and can help to formulate public health policies for optimizing hospital resource utilization for related diseases.

Abstract
BACKGROUND Traumatic brain injuries are common and costly to hospital systems. Most of the guidelines on management of traumatic brain injuries are taken from the Brain Trauma Foundation Guidelines. This is a review of the current literature discussing the evolving practice of traumatic brain injury. DATA SOURCES A literature search using multiple databases was performed for articles published through September 2012 with concentration on meta-analyses, systematic reviews, and randomized controlled trials. RESULTS The focus of care should be to minimize secondary brain injury by surgically decompressing certain hematomas, maintain systolic blood pressure above 90 mmHg, oxygen saturations above 93%, euthermia, intracranial pressures below 20 mmHg, and cerebral perfusion pressure between 60-80 mmHg. CONCLUSION Much is still unknown about the management of traumatic brain injury. The current practice guidelines have not yet been sufficiently validated, however equipoise is a major issue when conducting randomized control trials among patients with traumatic brain injury.

Abstract
AIMS The specific aims were to (1) define fever from the nurse's perspective; (2) describe fever management decision-making by nurses and (3) describe barriers to evidence-based practice across various settings. BACKGROUND Publication of practice guidelines, which address fever management, has not yielded improvements in nursing care. This may be related to differences in ways nurses define and approach fever. METHOD The collective case study approach was used to guide the process of data collection and analysis. Data were collected during 2006-7. Transcripts were coded using the constant comparative method until themes were identified. Cross-case comparison was conducted. The nursing process was used as an analytical filter for refinement and presentation of the findings. FINDINGS Nurses across settings defined fever as a (single) elevated temperature that exceeded some established protocol. Regardless of practice setting, interventions chosen by nurses were frequently based on trial and error or individual conventions -'what works'- rather than evidence-based practice. Some nurses' accounts indicated use of interventions that were clearly contraindicated by the literature. Participants working on dedicated neuroscience units articulated specific differences in patient care more than those working on mixed units. CONCLUSIONS By defining a set temperature for intervention, protocols may serve as a barrier to critical clinical judgment. We recommend that protocols be developed in an interdisciplinary manner to foster local adaptation of best practices. This could further best practice by encouraging individual nurses to think of protocols not as a recipe, but rather as a guide when individualizing patient care. There is value of specialty knowledge in narrowing the translational gap, offering institutions evidence for planning and structuring the organization of care.
