Transcallosal approach and post-operative subdural collections: 12-year paediatric neurosurgery tertiary centre experience.

Following transcallosal surgery for tumour resection, the formation of convexity or interhemispheric subdural cerebrospinal fluid collections may lead to clinical deterioration and may influence decision-making with regards to additional interventions. The aim of this study was to determine the incidence, risk factors, and management of subdural collections following the transcallosal approach in a paediatric cohort. A retrospective case note and radiological review of all children who underwent transcallosal surgery for intraventricular and thalamic tumours was carried out covering a 12-year period (2012-2023) in a single-centre tertiary paediatric neurosurgery unit. Parameters including demographics and clinical information including lesion location, pathology, extent of resection, need for and type of shunt required, as well as depth, laterality, and location of the collection were analysed prior to shunting, and at approximately 3 weeks, 3 months, and latest follow-up available post-operatively in order to further elucidate the natural history of these subdural collections and their clinical significance. Sixty-four cases satisfied the inclusion criteria of transcallosal surgery for tumour resection; 13 did not have adequate post-operative imaging and were excluded. Of the remaining 51 cases, there were 32 children (63%) with post-operative CSF subdural collections, of which 59% were ipsilateral, with the remainder showing bilateral distribution. The overall shunt insertion rate was 25.5% (12 ventriculoperitoneal and 1 subdural-peritoneal shunt) at 3 months, with a mean time to shunting of 19 days post-operatively. Children who developed post-operative subdural collections had a higher rate of shunting, at 37.5%, compared to 5.2% in those who did not. Pre- and post-operative hydrocephalus and subtotal resection were identified as risk factors for development of subdural collections post-operatively. Subdural collections showed a natural course of reduction and regression over follow-up, with the exception of 3 children where they persisted or increased over time; although none of these required shunting. Those children who underwent shunt insertion showed greater regression in the size of the subdural collection over time compared to the non-shunted group. In this paediatric cohort, 25.5 % of children required insertion of a shunt by 3 months following transcallosal surgery. Pre- and post-operative hydrocephalus and subtotal tumour resection were risk factors for development of subdural collections post-operatively.

Validation of the Turkish version of the pediatric early warning score

Aim: The pediatric early warning score (PEWS) identifies pediatric patients at risk for clinical deterioration and can helpless-experienced providers get a sense of which patients may need escalation of care. The purpose of the study was to adapt the PEWS into Turkish and evaluate its validity in pediatric patients admitted to the emergency. 
 Material and Methods: This study was conducted between May and October 2022 on 228 patients aged 17 and under in the pediatric emergency department of a tertiary care hospital. In the pilot phase of the study, scoring of the first 30 patients was performed by three nurses in the emergency department. In the second phase, the validity of the PEWS scale was evaluated. Validity of the scoring system in predicting admission was assessed using area under the receiver operating characteristics (ROC) curve (AUC), sensitivity, and specificity, positive predictive value (PPV) and negative predictive value (NPV).
 Results: The mean age of the children was 6.37 ± 4.72 years. Phase I demonstrated good inter-rater reliability (kappa = 0.75). In phase II, 22 patients (9.6%) were admitted to the intensive care unit (ICU) during the study period. AUC for predicting was 0.948 (95% CI: 0.915–0.981). According to ROC curve analysis, a cut-off value for PEWS score was found to be 4 (PEWS >4) for admitted to the ICU. Sensitivity and specificity in predicting ICU admission with the cut-off PEWS ≥4 was 86.36% and 90.78%, respectively (PPV, 50%; NPV, 90.48%). The sensitivity and specificity in predicting admission with a cut-off of PEWS ≥1 was 100% and 59.22%, respectively (PPV, 20.75%; NPV, 100%).
 Conclusion: The Turkish version of PEWS can be helpful in assessing patient status in pediatric emergency department with acceptable validity and can serve as a potentially screening tool for prediction of ICU admission.

Systemic Lupus Erythematosus Initially Presenting as Acute Motor andSensory Axonal Neuropathy Variant ofGuillain-Barre Syndrome ina Healthy Active Duty Female.

Guillain-Barre syndrome (GBS) is an acute monophasic immune-mediated polyradiculoneuropathy characterized by rapidly evolving ascending weakness, mild sensory loss, and hypo- or areflexia, typically progressing to peak symptoms over the course of 4 weeks. The precise mechanism is unclear but is proposed to be an immune-mediated reaction with the generation of antibodies against peripheral nerves triggered by a preceding viral infection. Acute motor and sensory axonal neuropathy (AMSAN) is a rare and severe variant of Guillain-Barre syndrome with limited published literature. Discussion of risk factors for this subtype has not been done in a systematic way. This case report involves a 34-year-old, active duty, West African female, who immigrated to the United States in 2019. She presented with worsening diplopia, bilateral distal upper and lower extremity paresthesias as well as progressively worsening bilateral upper extremity weakness. Her clinical picture was complicated by constitutional symptoms, diffuse lymphadenopathy, no preceding viral illness, and marked clinical deterioration. Ultimately, she was diagnosed with acute motor and sensory axonal neuropathy in the setting of a new diagnosis of systemic lupus erythematosus, a rarely described association emphasizing the importance of a thorough evaluation for underlying causes of acute neurologic pathologies.

Performance of risk scores in patients with acute exacerbations of COPD.

Acute exacerbations of COPD (AECOPD) are common causes of hospitalization. Various scoring systems have been proposed to classify the risk of clinical deterioration or mortality in hospitalized patients with AECOPD. We sought to investigate whether clinical deterioration and mortality scores at admission can predict adverse events occurring during hospitalization and after discharge of patients with AECOPD. We performed a retrospective study of patients admitted with AECOPD. The National Early Warning Score 2 (NEWS2), the NEWS288-92%, the Dyspnea, Eosinopenia, Consolidation, Acidemia, and atrial Fibrillation (DECAF) score, and the modified DECAF (mDECAF) score were calculated at admission. We assessed the sensitivity, specificity, and overall performance of the scores for the following outcomes: in-hospital mortality; need for invasive mechanical ventilation or noninvasive ventilation (NIV); long hospital stays; hospital readmissions; and future AECOPD. We included 119 patients admitted with AECOPD. The median age was 75 years, and 87.9% were male. The NEWS288-92% was associated with an 8.9% reduction in the number of individuals classified as requiring close, continuous observation, without an increased risk of death in the group of individuals classified as being low-risk patients. The NEWS288-92% and NEWS2 scores were found to be adequate in predicting the need for acute NIV and longer hospital stays. The DECAF and mDECAF scores were found to be better at predicting in-hospital mortality than the NEWS2 and NEWS288-92%. The NEWS288-92% safely reduces the need for clinical monitoring in patients with AECOPD when compared with the NEWS2. The NEWS2 and NEWS288-92% appear to be good predictors of the length of hospital stay and need for NIV, but they do not replace the DECAF and mDECAF scores as predictors of mortality.

Critical Emergency Department Interventions and Clinical Deterioration in Children With Nonsevere Traumatic Intracranial Hemorrhage.

Substantial practice variation exists in the management of children with nonsevere traumatic intracranial hemorrhage (tICH). A comprehensive understanding of rates and timing of clinically important tICH, including critical interventions and deterioration, along with associated clinical and neuroradiographic characteristics, will inform accurate risk stratification. We conducted a single-center retrospective cohort study of children aged younger than 18 years evaluated in the emergency department (ED) from May 1, 2014 to February 28, 2020 with tICH and initial Glasgow Coma Scale (GCS) score of higher than 8. We determined rates of clinically important tICH after injury and within 96 hours of ED arrival, defined as immediate ED interventions (intubation, hyperosmotic agents, or neurosurgery within 4 hours of arrival) or clinically important deterioration (signs/symptoms with change in management). Associations between outcome and clinical and neuroradiographic characteristics were calculated using individual logistic regression models. Our sample included 135 children. Clinically important tICH was observed in 13.3% (n = 18); 9 (6.7%) underwent immediate ED interventions and 9 (6.7%) developed deterioration. Most (93.3%, n = 127) presented with an initial GCS ≥ 14, including all children who later deteriorated. Initial GCS ( P = 0.001) and nonaccidental trauma ( P = 0.024) mechanism were associated with the outcome. None of the 71 (52.6%) children with initial GCS ≥ 14, isolated, nonepidural hemorrhage after accidental injury developed clinically important tICH. Clinically important tICH occurred in 13% of children with nonsevere tICH, and 7% of children who did not undergo immediate ED interventions later deteriorated, all of whom had an initial GCS ≥ 14. However, a subgroup of children was identified as low risk based on clinical and neuroradiographic characteristics.

Modified Early Warning Score: Clinical Deterioration of Mexican Patients Hospitalized with COVID-19 and Chronic Disease.

Retrospective observational study, 430 hospitalized patients with COVID-19 and chronic disease. Instrument, Modified Early Warning Score (MEWS). Data analysis, with Cox and logistic regression, to predict survival and risk. Of 430 patients, 58.6% survived, and 41.4% did not. The risk was: low 53.5%, medium 23.7%, and high 22.8%. The MEWS score was similar between survivors 3.02, p 0.373 (95% CI: -0.225-0.597) and non-survivors 3.20 (95% CI: -0.224-0.597). There is a linear relationship between MEWS and mortality risk R 0.920, ANOVA 0.000, constant 4.713, and coefficient 4.406. The Cox Regression p 0.011, with a risk of deterioration of 0.325, with a positive coefficient, the higher the risk, the higher the mortality, while the invasive mechanical ventilation coefficient was negative -0.757. By providing oxygen and ventilation, mortality is lower. The predictive value of the modified early warning score in patients hospitalized for COVID-19 and chronic disease is not predictive with the MEWS scale. Additional assessment is required to prevent complications, especially when patients are assessed as low-risk.

Low Dose Fractionated Radiation Therapy as a Chemo-Potentiator of Salvage Temozolomide (TMZ) for Recurrent Anaplastic Astrocytoma (AA) and Glioblastoma Multiforme (GBM): A Single-Arm Phase I/II Trial

Cell survival curves demonstrate low-dose radiation hypersensitivity, with steepest cell kill at 0.3-0.5 Gy/fx. This phase 1/2 study assessed the safety and efficacy of low-dose fractionated radiation therapy (LDFRT) as a chemopotentiator of concurrent TMZ for patients with recurrent GBM or AA. Patients with recurrent GBM or AA s/p standard of care therapy and ≥12 months from prior RT and ≥2 months from prior TMZ were eligible to receive 0.5 Gy of RT twice daily for 10 fx with concurrent TMZ (150-200 mg/m2), both delivered in 5 consecutive days of a 28-day cycle for up to 6 cycles, followed by 6 more cycles of adjuvant TMZ. In phase 1, hematologic toxicity was assessed 1 month after starting therapy. Brain MRIs were obtained every 2 months, or every 1 month in cases of potential progression. Progression was defined by RANO criteria. Pseudoprogression consisted of MRI changes independent of clinical deterioration or steroid use that stabilize/reverse without oncologic intervention. The primary endpoint was 1-year overall survival (OS), with a lower bound of an 80% CI >28% deemed promising for further study based on historical data. Secondary endpoints were rates of pseudoprogression and hematologic toxicity. Thirty-one patients were enrolled/analyzed. Grade 3-4 acute hematologic toxicity was seen in 8 (27%) patients. Median follow-up was 9.5 (range: 0.1-66.3) months (mos). Median and 1-yr OS were 9.6 (95% CI = 7.0-15.4) mos and 34.5% (95% CI = 20.9%-57.0%). The lower bound of the 80% CI for 1-yr OS was 24.8%. 77% of patients experienced pseudoprogression, with a median time to pseudoprogression from start of LDFRT of 1.9 (95% CI = 1.7-4.4) mos and median duration of 3.6 (95% CI = 1.6-Not estimable) mos. Patients with pseudoprogression had improved OS vs. those without (N = 6; median 10.6 vs 3.9 mos, HR = 0.12 [95% CI = 0.03-0.40]; P < 0.01). LDFRT in the re-irradiation setting for GBM or AA was safe. High rates of pseudoprogression were observed at strikingly low RT doses, with improved OS amongst patients with vs. without pseudoprogression. While pseudoprogression is common at definitive doses of brain RT, it is rare at palliative doses (e.g., 30 Gy/10 fx). Thus, low-dose RT hypersensitivity may be elicited by LDFRT with TMZ for patients with GBM/AA. Further study is needed to optimally apply this radiobiological property to improve patient outcomes.

A Cancer Patient With a Bloody Cough

Hemoptysis, a condition presenting with varying degrees of severity, can be a result of a wide variety of conditions. Its comprehensive assessment requires evaluating patient stability, airway patency, and implementing an extensive diagnostic protocol. Critical to patient management is a broad differential diagnosis, accurate targeting of the identified etiology, and vigilant monitoring for signs of clinical deterioration. Although life-threatening manifestations necessitate multidisciplinary intervention, mild hemoptysis may be managed with only supportive measures. Nurse Practitioners can provide impactful care for hemoptysis patients and should expand their education on its presentation, causes, and management.

Dexmedetomidine use for patients in palliative care with intractable pain and delirium: A retrospective study.

Patients seen by the palliative care team often have difficult and intractable symptoms. The current standard of practice to manage these symptoms is the deeply sedating midazolam continuous subcutaneous infusion for patients who are expected to expire within hours to days. Dexmedetomidine provides sedation but lacks evidence in palliative care use. This study describes continuous subcutaneous infusion of dexmedetomidine's effect on refractory pain and delirium. Retrospective, observational chart review and conducted in accordance with SQUIRE (quality improvement study). Twenty adult patients (18 years of age or older) with metastatic cancer disease admitted to three palliative complex care units of Fraser Health who received continuous subcutaneous infusion of dexmedetomidine between January 2017 to August 31, 2019. Average length of dexmedetomidine use was 9 days (1/3 length of stay). Eight of the 13 patients with pain symptoms exhibited an overall decline in pain. Four of the 6 patients with delirium had an initial decrease in delirium, but it did not last beyond the first day. Despite progressive clinical deterioration, adjunctive medications decreased or remained the same for 53% of as needed medications and 65% for regularly scheduled medications. Forty-five percent of patients had ≥50% days of rousable sedation. Hypotension occurred in 85% of patients. Dexmedetomidine provided benefit in managing intractable pain while allowing patients to remain rousable, but only had a short effect on delirium symptoms.

Noninvasive Assessment of Impaired Gas Exchange with the Alveolar Gas Monitor Predicts Clinical Deterioration in COVID-19 Patients.

The COVID-19 pandemic magnified the importance of gas exchange abnormalities in early respiratory failure. Pulse oximetry (SpO2) has not been universally effective for clinical decision-making, possibly because of limitations. The alveolar gas monitor (AGM100) adds exhaled gas tensions to SpO2 to calculate the oxygen deficit (OD). The OD parallels the alveolar-to-arterial oxygen difference (AaDO2) in outpatients with cardiopulmonary disease. We hypothesized that the OD would discriminate between COVID-19 patients who require hospital admission and those who are discharged home, as well as predict need for supplemental oxygen during the index hospitalization. Patients presenting with dyspnea and COVID-19 were enrolled with informed consent and had OD measured using the AGM100. The OD was then compared between admitted and discharged patients and between patients who required supplemental oxygen and those who did not. The OD was also compared to SpO2 for each of these outcomes using receiver operating characteristic (ROC) curves. Thirty patients were COVID-19 positive and had complete AGM100 data. The mean OD was significantly (p = 0.025) higher among those admitted 50.0 ± 20.6 (mean ± SD) vs. discharged 27.0 ± 14.3 (mean ± SD). The OD was also significantly (p < 0.0001) higher among those requiring supplemental oxygen 60.1 ± 12.9 (mean ± SD) vs. those remaining on room air 25.2 ± 11.9 (mean ± SD). ROC curves for the OD demonstrated very good and excellent sensitivity for predicting hospital admission and supplemental oxygen administration, respectively. The OD performed better than an SpO2 threshold of <94%. The AGM100 is a novel, noninvasive way of measuring impaired gas exchange for clinically important endpoints in COVID-19.

OXYGEN CONSUMPTION AS AN EARLY WARNING SYSTEM IN THE CRITICALLY ILL.

Introduction: In this study, we assessed whether changes in oxygen consumption (VO 2 ) and other metabolic parameters could be used as an early warning system for detecting clinical deterioration in mechanically ventilated patients. Methods: This was a prospective cohort study of adult patients requiring mechanical ventilation between February 2016 and March 2019. We looked for changes in VO 2 , carbon dioxide production (VCO 2 ), respiratory quotient (RQ), and end-tidal carbon dioxide (EtCO 2 ), occurring prior to clinical deterioration. Clinical deterioration was predefined as a requirement of vasopressor, an increase in serum lactate by 20% where at least one value was above 3 mmol/L, or a decrease in hemoglobin by 20% in the 4 hours prior to clinical deterioration. Results A total of 141 patients were included. There were no detectable changes in VO 2 , VCO 2 , and EtCO 2 within the 4 hours prior to any clinical deterioration. RQ increased significantly within the 4 hours prior to an increase in lactate as compared with no increase in lactate, but there were no detectable changes prior to other clinical deteriorations. Conclusions RQ has the potential to be an early marker of tissue hypoperfusion or mitochondrial dysfunction. However, future studies are necessary to evaluate the use of RQ as a bedside monitor in critical care settings.

Strengthening public health policies for childhood cancer: Peru's achievements through the WHO Global Initiative for Childhood Cancer.

To report the progress in Peru, since June 2019, in the implementation of the World Health Organization Global Initiative for Childhood Cancer using the CureAll framework, which can be replicated in low- and middle-income countries. A mixed method was used of participatory and documentary evaluation. The participatory evaluation included stakeholders from various government institutions, nonprofit organizations, and international partners. The documentary aspect consisted of a review of data on the regulatory environment, national projects, and interventions implemented. The Ministry of Health engaged more than 150 participants to form working committees, which have developed policy and regulatory documents to strengthen care services. Achievements include a decrease in the national treatment abandonment rate from 18.6% to 8.5%, the approval of the Childhood Cancer Law, improvements in the management of patients with febrile neutropenia, and a reduction in rates of events of clinical deterioration and mortality of hospitalized patients. The Cure All implementation framework allows local teams to implement specific strategies and monitor early outcomes in pediatric oncology. The results obtained reflect the teamwork, the leadership of the authorities, the technical support of professionals, and the support of involved organizations. Further actions will be needed to guarantee sustainability, and monitoring tools are needed to assure success in the planned activities.

42 Enacting Meaningful Change in the Face of Adversity – Use of a Sentinel Event to Pilot the Creation of a Rapid Response System in a Tertiary Paediatric Care Centre

Abstract Introduction/Background Although rare, in-hospital paediatric mortality occurs at a rate of 12.66 per 1000 admissions. Delayed recognition of clinical deterioration is a modifiable factor in such adverse events. In paediatric patients, subtle changes in vital signs often precede acute deterioration and provide an opportunity for early intervention and prevention of further deterioration. Based on this rationale, rapid response systems (RRS), which include a critical care response team (CCRT) and a Paediatric Early Warning Score (PEWS), have been established to facilitate the detection of clinical deterioration and mobilize resources for timely treatment. There is evidence that RRS can significantly decrease inpatient clinical deterioration events and PICU utilization. Objectives At our institution, serious patient safety events identified system failures in recognition, communication, and escalation of care in response to clinical deterioration. The root cause analysis led to a quality improvement and patient safety initiative to implement an RRS at our tertiary paediatric care centre. Design/Methods Process implementation of this pilot project required consultations with key stakeholders and designation of unit champions to mobilize resources and promote buy-in. Based on other successful implementation strategies, we adopted the Modified Brighton PEWS, defined a response algorithm, created bedside tools, constructed an interdisciplinary CCRT, and organized simulation activities to implement the new process. We used the Plan-Do-Study-Act method to carry out change based on weekly feedback from frontline workers. To assess the feasibility and acceptability of this initiative, all CCRT activations during the pilot phase were reviewed and a survey was distributed pre- and post-implementation. The number of code blues and mortality data will also be measured. Results The pilot period spanned June to September 2022 on our medical inpatient unit. Average response time to CCRT activation was 12 minutes (IQR 7-13.5), a median of three therapeutic interventions were required per activation, and 33% of activations resulted in PICU admissions. Among the 27 post–implementation survey respondents, 87% identified CCRT as a useful addition to optimize care and address patient safety concerns. Qualitatively, it has created a shared safety culture and empowered junior members of healthcare teams to escalate care. Conclusion This quality improvement initiative pilot study has demonstrated feasibility and acceptability of RRS implementation with a positive impact on patient safety culture and earlier detection and intervention for deteriorating patients. Further prospective comparative clinical benefits and cost-benefit analyses are needed to support hospital-wide implementation.

Characteristics of patients who return unplanned to the ED, and factors that contribute to their decision to return: Integrated results from an explanatory sequential mixed methods inquiry

AimTo identify common characteristics of patients who return to the ED unplanned and factors that may contribute to their decision to return. BackgroundReturn visits to the Emergency Department (ED) have been associated with adverse events and deficits in initial care provided. There is increasing evidence to suggest that many return visits may be preventable. MethodsThe results of primary quantitative measures (QUAN) followed by qualitative measures (qual) were integrated to build on and explain the quantitative data found in the initial phase of the research. ResultsIntegration of results produced three new findings. 1) Most return visits occurred beyond 48 hrs because patients intentionally delayed going back to the ED despite their persisting symptoms; 2) Clinical urgency and deterioration were rarely evident in patients who made return visits in patients and 3) Ineffective communication between the clinician and the patient at discharge may have contributed to patients making the decision to return to the ED. ConclusionThe decision to return unplanned to the ED is not an immediate response for most patients, and several potentially avoidable factors may influence their decision-making process. Future research should focus on strategies which contribute to the avoidance of unplanned return visits.

Droxidopa or Atomoxetine for Refractory Hypotension in Critically Ill Cardiothoracic Surgery Patients

To evaluate the effects of droxidopa or atomoxetine on intravenous (IV) vasoactive agent discontinuation in cardiothoracic intensive care unit (ICU) patients with hypotension refractory to midodrine. Single-center, retrospective cohort study. Tertiary- and quaternary-care university teaching hospital. Included patients who received at least 4 consecutive doses of droxidopa or atomoxetine and remained on concurrent midodrine. Patients were excluded if they received study medication before admission, had clinical deterioration after study medication initiation requiring additional vasoactives/escalation of IV vasoactive dosage for at least 12 hours, had a diagnosis of hepatorenal syndrome, were prisoners, or were pregnant. Droxidopa, atomoxetine, or both. The primary endpoint was time to discontinuation of IV vasoactive agents after initiation of study medication, analyzed usinga Kaplan-Meierestimate with the Wilcoxon method, censoring death within 24 hours of the last dose of study medication. Noadjustment for repetitive analyses wasmade, as the analysis was hypothesis-generating. Of the 72 charts reviewed, 45 patients met inclusion criteria (18 atomoxetine, 17 droxidopa, and 10 both). There were no differences in median time to discontinuation of IV vasoactive agents (21.9 days v 8.0 days v 13.9 days, respectively; p=0.259) or ICU or hospital length of stay between groups. A higher percentage of patients who survived to hospital discharge received both study medications or droxidopa alone (90% v 76.5%) than atomoxetine alone (44.4%, p=0.028). Droxidopa and atomoxetine are oral vasoactive agents with potential mechanisms to facilitate IV vasopressor weaning for patients in the ICU with hypotension refractory to midodrine, but further prospective research is needed.

Monocyte Count and Systemic Immune-Inflammation Index Score as Predictors of Delayed Cerebral Ischemia after Aneurysmal Subarachnoid Hemorrhage.

Delayed cerebral ischemia (DCI) is a major cause of disability in patients who survive aneurysmal subarachnoid hemorrhage (aSAH). Systemic inflammatory markers, such as peripheral leukocyte count and systemic immune-inflammatory index (SII) score, have been considered predictors of DCI in previous studies. This study aims to investigate which systemic biomarkers are significant predictors of DCI. We conducted a retrospective, observational, single-center study of 170 patients with SAH admitted between May 2018 and March 2022. We analyzed the patients' clinical and laboratory parameters within 1 hour and 3-4 and 5-7 days after admission. The DCI and non-DCI groups were compared. Variables showing statistical significance in the univariate logistic analysis (p<0.05) were entered into a multivariate regression model. Hunt-Hess grade "4-5" at admission, modified Fisher scale grade "3-4" at admission, hydrocephalus, intraventricular hemorrhage, and infection showed statistical significance (p<0.05) on a univariate logistic regression. Lymphocyte and monocyte count at admission, SII scores and C-reactive protein levels on days 3-4, and leukocyte and neutrophil counts on days 5-7 exhibited statistical significance on the univariate logistic regression. Multivariate logistic regression analysis revealed that monocyte count at admission (odds ratio [OR], 1.64; 95% confidence interval [CI], 1.04-2.65; p=0.036) and SII score at days 3-4 (OR, 1.55; 95% CI, 1.02-2.47; p=0.049) were independent predictors of DCI. Monocyte count at admission and SII score 3-4 days after rupture are independent predictors of clinical deterioration caused by DCI after aSAH. Peripheral monocytosis may be the primer for the innate immune reaction, and the SII score at days 3-4 can promptly represent the propagated systemic immune reaction toward DCI.

Newly diagnosed type 1 diabetes mellitus in a human immunodeficiency virus-infected patient with antiretroviral therapy-induced immune reconstitution inflammatory syndrome: a case report

BackgroundDiabetes that develops in human immunodeficiency virus (HIV)-infected patients who receive antiretroviral therapy (ART) is usually type 2 diabetes mellitus (T2DM); however, autoimmune diabetes, such as type 1 diabetes mellitus (T1DM) can also develop in this population. After treatment with ART, patients might experience clinical deterioration following an increase in the CD4 cell count, which is termed immune reconstitution inflammatory syndrome (IRIS). Here, we describe an HIV-infected patient on ART who developed T1DMat due to IRIS, highlighting the clinical complexity in diagnosis and treatment.Case presentationA 36-year-old man infected with HIV had a nadir CD4 cell count of 15.53/μL before medication, which increased to 429.09/μL after 9 months of regular ART. The fasting serum glucose at 9 months was between 96 mg/dL and 117 mg/dL. After 11 months of ART, the patient was admitted to hospital for diabetic ketoacidosis (DKA) and Graves’ disease (GD). Noninsulin antidiabetics (NIADs) were prescribed following the resolution of DKA. However, poor glycemic control was noted despite well-titrated NIADs. Further investigation demonstrated poor pancreatic beta cell function and elevated anti-glutamic acid decarboxylase (anti-GAD) and anti-tyrosine phosphatase-like insulinoma antigen 2 (anti-IA2) titers. According to the results, he was diagnosed with T1DM and received multiple daily injections(MDI) of insulin. The regimen of MDI was insulin degludec as basal insulin and insulin aspart as prandial insulin. After MDI therapy, his glycemic control was improved.ConclusionIn this case, T1DM was ascribed to IRIS. Although this phenomenon has been demonstrated in previous case reports, further study is necessary to realize the mechanism of this association. Therefore, we emphasize that when HIV-infected patients on ART experience an unstable blood glucose level and abnormal thyroid function, physicians should consider T1DM and GD associated with ART-induced IRIS to reduce the subsequent complications and more serious endocrine dysfunction.

Pulmonary Arterial Hypertension in the Elderly: Peculiar Features and Challenges for a Proper Phenotyping Approach.

(1) Introduction. Although pulmonary arterial hypertension (PAH) usually affects young people with a low cardiovascular risk profile, progressive epidemiologic changes have been providing a codified phenotype of elderly subjects with PAH and increased risk predictors for left heart disease. We therefore conducted a systematic review to describe the current knowledge and characteristics of elderly individuals with PAH and further insights concerning their prognostic outcomes and therapeutic response. (2) Methods. A search was conducted in PubMed, Embase, and Cochrane Library for publications evaluating the epidemiology, diagnostic work-up, and treatment of PAH in elderly subjects. (3) Among the 74 publications initially retrieved, 16 full-text articles were selected for the present systematic review. Compared to their younger counterparts, elderly individuals with PAH showed greater clinical deterioration, reduced exercise capacity, and worse prognostic outcomes, as well as less response to PAH-targeted therapy and higher rates of PAH drug discontinuation. (4) Conclusions. Demographic changes over time contributed to define a peculiar PAH phenotype in elderly patients, with an increased burden of cardiovascular comorbidities and distinctive features compared to young patients. Further investigations are needed in order to better clarify the nosologic criteria, and management in this subset population.

Pediatric Early Warning System in the Short Stay Unit

INTRODUCTION: Pediatric Early Warning Scores were developed as standardized clinical aides for early recognition of clinical deterioration in children. These systems improve situational awareness among professionals. A major concern is the workload increase. After implementation in the Short Stay Unit, we intended to evaluate its effectiveness in our population.METHODS: We reviewed medical records of children admitted to the Short Stay Unit between July 2017 and February 2020. We developed a statistical analysis to evaluate the test performance.RESULTS: One thousand three hundred twenty-three patients were included (median age 3.07 years-old); 5.7% were considered to have clinical deterioration (maximum score median 7.00 vs 2.00) (p&lt;0.001). The area under the ROC curve was 0.947. Defining 4 as cut-off value, the sensitivity is 97.1% (specificity 82.7%).CONCLUSION: This score proved to be a good test for early identification of clinical deterioration in our population.

283 An online portal to monitor trends of patients clinically deteriorating or requiring transfer from a rehabilitation hospital for older persons

Abstract Background Due to advances in Healthcare, more medically complex Older Persons are admitted to our Rehabilitation Hospital for Older Persons following an inpatient stay in an Acute Hospital. We created a deteriorating patient working group along with an online portal in July 2022 to ensure hospital wide procedures are in place for the early identification, escalation and management of deteriorating patients. Our online portal monitors patients clinically deteriorating or requiring transfer to an Acute Hospital following admission to our Rehabilitation Hospital for Older Persons. Methods Patients clinically deteriorating and patients requiring transfer to an Acute Hospital are captured in separate electronic databases respectively on our secure online portal. We present patient data from August 1st 2022 to June 1st 2023 following the creation of the online portal. Results A total of 143 patient episodes at risk of clinical deterioration were entered into the portal from August 1st 2022 to June 1st 2023. A total of 61 patient episodes requiring transfer back to an acute Hospital were entered into the portal from August 1st 2022 to June 1st 2023. Conclusion Our Rehabilitation Hospital for Older Persons assesses the suitability of patients for rehabilitation a local acute hospital prior to accepting their care. Most patients who clinically deteriorate can be managed in our hospital but due to our limited access to more advanced treatments and diagnostics, some patients require transfer back to the acute hospital from which they were referred. The creation of a secure online portal has been a very useful means of monitoring trends in our Hospital of both patients who clinically deteriorate and those who require transfer.
