Abstract 4127513: Cardiopulmonary long-term effects 6, 18 and 30 months after severe covid-19 infection

Background: SARS-CoV-2 infection affects the cardiopulmonary system in both the acute and long-term phase. This study aimed to comprehensively assess symptoms and potential long-term impairments 6, 18 and 30 months in patients previously hospitalized for severe Covid-19 infection. Methods: This prospective registry included patients hospitalized for PCR-confirmed Covid-19 infection. Approximately 6 months post-discharge, follow-up examination included patient history, clinical examination, echocardiography, electrocardiogram, cardiac magnetic resonance imaging (cMRI), chest computed tomography (CT) scan, pulmonary function test (PFT), six-minute walk test (6MWT) and a comprehensive laboratory panel. Patients with pathologic findings during the first visit underwent a second (at 18 months) and third (at 30 months) follow-up examination. Those without pathologic findings or who refused further medical examinations were contacted via phone to inquire about symptoms. Results: Between July 2020 and April 2022, 200 patients (91% general ward, 9% intensive care unit) were recruited. Due to dropouts, the second visit was conducted in 170 patients, and the third visit in 139 (74 in person, 65 via telephone). Long Covid criteria were fulfilled by 73% at 6 months, 52% at 18 months and 49% at 30 months post-discharge, with fatigue being the most common symptom (Figure 1). Echocardiography at 6 months showed impaired left ventricular function in 15 patients, with normalization in 80% at 18 months and further 66% at 30 months (Figure 2). cMRI revealed pericardial effusions in 28 patients at 6 months, which resolved in 47% at 18 months and in further 60% at 30 months. Signs of peri- or myocarditis were present in 7 patients at 6 months and were resolved in all 4 patients who attended control studies at 18 months. Chest CT scans at 6 months identified post-infectious residues in 41 patients, with full recovery in 20% at 18 months without further normalization after 30 months. The length of in-hospital stay was identified as a significant predictor for persisting Long Covid 6 months after discharge (95% CI: 1.005 - 1.12, p=0.03). Conclusion: While the prevalence of Long Covid decreased over time, a significant symptom burden persisted at 6, 18 and even 30 months after severe Covid-19 infection. Structural and functional abnormalities were less frequent compared to reported symptoms, posing a challenge in substantiating the causes of these symptoms.

Abstract 4136550: In-hospital cardiac arrest can be detected by Innovative smart healthcare syste

Background: Predicting in-hospital cardiac arrest (IHCA) is crucial for preventing patient fatalities. However, it remains challenging due to the irregularities in time series data across various features. Previous studies relied on traditional medical scoring systems, but their accuracy was limited as the models were overly simplistic. Recent research using machine learning methods has shown improved results. In our work, we employ deep learning and time series approaches, which are considered the most powerful models for addressing complex problems in recent years. Method/Research Design: The cohort study took place in a hospital in Taiwan from January 2016 to August 2022, involving 252,000 patients in general wards. Input data encompassed basic information, vital signs, Glasgow Coma Scale scores, medication, etc., to predict IHCA occurrences within 24 hours. Given the immediacy of IHCA events, we utilized left alignment to handle time series. Evaluation metrics included the area under the receiver operating characteristic curve (AUROC). Results: We compared three types of settings. The first was based on scoring systems, where the national early warning system (NEWS) achieved an AUROC of 0.756, and the modified early warning score (MEWS) reached 0.653. In the next setting, based on the data summary within a given time interval, the machine learning models XGBoost and deep learning model TabNet achieved AUROCs of 0.863 and 0.839, respectively. This indicates that machine learning outperforms traditional medical methods. The final setting involved time series analysis, where XGBoost and the Gate Recurrent Unit (GRU) network achieved 0.848 and 0.904, respectively, surpassing all previous settings. Conclusion: Our study demonstrates that learning-based methods outperform rule-based methods in predicting IHCA events. Machine learning algorithms offer more possibilities and have the potential to address complex problems effectively. Moreover, considering time series data rather than summarizing within fixed intervals preserves information and leads to better scores. Leveraging the time series deep learning method, GRU shows promising potential in significantly reducing the risk of IHCA events.

Clinical Benefits of Sustained Oral Nirmatrelvir/Ritonavir Use for the Outpatient Treatment of COVID-19: Findings from the Taiwanese Health Authority Perspective Using a Decision Tree Modeling Approach

Despite the observed clinical benefits of nirmatrelvir/ritonavir (NMV/r), it is uncertain whether Taiwan will continue covering NMV/r for high-risk individuals with mild-to-moderate coronavirus disease 2019 (COVID-19). This analysis assessed the impact of sustained utilization of NMV/r on COVID-19-associated healthcare resource utilization (HCRU) and mortality from the Taiwanese health authority perspective (THAP). A decision tree model estimated the incremental number of clinical events associated with NMV/r utilization over a 30-day period. Model results compared (1) a base case using current rates of NMV/r from the THAP, and (2) a hypothetical scenario assuming the current supply of NMV/r is not extended in Taiwan. NMV/r utilization rates included 80% and 0% in the base case and hypothetical scenario, respectively. Outcomes included the number of hospitalizations involving a general ward (GW) stay, intensive care unit (ICU) stay, and mechanical ventilation (MV) use, as well as the number of bed days, symptom days, and hospitalization deaths. Based on epidemiologic data, 150,255 patients with COVID-19 were eligible for treatment from the THAP. In the hypothetical scenario, HCRU increased by 175% compared to the base case, including increases in hospitalizations involving GW, ICU, and MV use (differences: 2067; 623; 591, respectively), bed days (difference: 51,521), symptom days (difference: 51,714), and deaths (difference: 480). Findings indicate that sustained utilization of NMV/r from the THAP reduces the clinical burden of mild-to-moderate COVID-19 through the reduced incidence of COVID-19-related HCRU and deaths.

Development of Streptococcus pyogenes pneumnonia and pleural empyema post-chickenpox infection in a 5-year-old child: A case report

Background: The introduction of the varicella vaccine has led to a significant decrease in pediatric varicella-induced invasive Streptococcus pyogenes (group A streptococcal [GAS]) infections. However, the development of a pleural empyema following a chickenpox infection is a rare complication in pediatric patients. Case presentation: In this report, we present a 5-year-old male patient who presented to the emergency department with a deteriorating course two days after a chickenpox infection. The patient complained of high-grade documented fever, a congested throat, abdominal pain, shortness of breath, and most importantly, decreased air entry on the right side of the chest, along with the presence of crepitations. Such a deteriorated clinical picture suggested the presence of an infectious cause. The patient’s physical examination and radiological imaging provided evidence for the presence of lower right-sided lobar pneumonia. On the second day of hospitalization, the patient showed worsening respiratory distress, prompting further investigations that confirmed the development of a right-sided pleural empyema through radiological imaging. Pediatric surgery consultation was requested, and 500 cc of pus was drained following the insertion of a chest tube, which was later sent for analysis. The patient’s clinical picture improved significantly following this intervention. Due to the severity of his condition, the patient was transferred to the pediatric intensive care unit (PICU) for close monitoring. After one night in the PICU, during which his condition stabilized and oxygen therapy was gradually weaned off, the patient continued to improve on the general ward. Daily assessments and laboratory tests showed decreasing inflammatory markers and resolution of symptoms. Following three days of admission and confirmation of no underlying immunologic deficiency, the patient was discharged home with appropriate antibiotic therapy and follow-up instructions. Discussion: Similar cases have been sporadically documented in pediatric literature, with notable examples involving older patients. The pathophysiology involves complex immune interactions and virulence factors of GAS, contributing to severe outcomes such as pleural effusion. Conclusion: In this case, the 5-year-old patient experienced a severe progression from chickenpox to pleural empyema but ultimately improved following prompt medical intervention and chest tube drainage. The patient was discharged after a successful recovery, highlighting the efficacy of early recognition and treatment in managing such complications.

Cognizance of patients’ rights towards health in a teaching hospital in Sindh, Pakistan: A comparative study

Objectives The objective of this study is to compare cognizance of patients’ rights among patients and doctors. Material and Methods The comparative cross-sectional study was undertaken in various wards of a teaching hospital in Sindh, Pakistan to explore cognizance of patients’ rights among patients and doctors. A total of 390 patients and 417 doctors were selected from the general medicine and general surgery wards of a teaching hospital in Sindh, Pakistan, from December 01, 2021 to February 28, 2022, through convenience sampling. A validated, pre-guided questionnaire was used for data collection. SPSS version 26.0 was used for analysis. The cumulative and segregated analysis of mean ± standard scores of patients’ and doctors’ cognizance regarding patients’ rights were assessed using an independent t-test. Result The segregated analysis of the mean scores of cognizance of patients’ rights among patients and doctors revealed that the majority of associations were statistically significant (p < 0.05), with a few exceptions. These included the right to receive the best available care and respect (p = 0.29), the right to know about their treatment in an understandable language (p = 0.23), and the right to receive healthcare in a hygienic, clean, and safe environment (p = 0.79). Conclusion There is a significant difference in the levels of cognizance regarding patients’ rights between patients and doctors.

Proton pump inhibitors in inpatients: Are we getting it right? A retrospective analysis

Background: Proton pump inhibitors (PPIs) are commonly prescribed to hospitalized patients, but many of these prescriptions may not be based on evidence-based indications. It’s important to understand that inappropriate prescribing of PPIs can lead to unnecessary medications and financial burdens. Unfortunately, there are not many recent studies exploring how often PPIs are prescribed and if they are being prescribed appropriately. Objective: The study aimed to assess the appropriateness of PPIs use among hospitalized patients. It evaluated the indications for PPIs use and determined whether the use of PPIs in hospitalized patients is justified or not. Setting: The study was conducted at Hamad General Hospital, a tertiary academic healthcare center in the state of Qatar. Methods: A retrospective observational study with 201 subjects, was conducted in general internal medicine wards at a tertiary hospital. Physician documentation and inpatient and outpatient medication prescriptions were analyzed for PPIs exposure. Main outcome measures: The appropriateness of exposure to PPIs is determined based on international recommendations. Results: Of 533 hospitalized patients who were not critically ill, 201 (37.7%) were prescribed PPIs. The study found that 65.2% of the patients had no valid indication for PPIs exposure. Furthermore, 18% of patients were inappropriately prescribed stress ulcer prophylaxis with PPIs even though they had a low risk for the development of ulcer disease. After discharge, 82.6% of patients were prescribed PPIs, with the most common indication (43%) being gastrointestinal ulcer prophylaxis. Conclusion: This study sheds light on the issue of overutilization of PPIs, specifically in non-critically ill hospitalized patients. It highlights the unnecessary continuation of PPI prescriptions at discharge and emphasizes the importance of physicians reevaluating PPI prescriptions periodically to ensure they are still necessary and discontinuing them when possible to avoid unwanted consequences.

WOUND DRESSINGS FOR SORPTION THERAPY IN THE TREATMENT OF PURULENT WOUNDS: a review article

Surgical infections remain one of the most challenging and urgent issues in modern medicine, reaching a socio-ecological scale of significance nationwide. Despite advances in treating purulent wounds, the prevalence of patients with purulent surgical infections remains high. According to both domestic and international sources, surgical patients with purulent-inflammatory conditions comprise 35–45% of the total patient population in general surgery wards. In some cases, purulent infections become acute and can lead to the generalization of the purulent process, resulting in sepsis and even death. Mortality rates from acute surgical infections range from 19% to 70% within surgical hospitals. Additionally, there has been an increase in the transition of acute purulent processes to chronic stages, which prolongs the treatment duration for these patients. The prevention and treatment of surgical infections are therefore of paramount importance, representing one of the core challenges in surgical care. Optimal local treatment of purulent wounds requires adherence to essential principles, including active surgical intervention, antibiotic therapy throughout the wound healing stages, and local wound management under bandages. An analysis of the literature reveals that sorption-application therapy is gaining prominence in modern surgical practice for local wound management. This approach, which utilizes advanced interactive wound dressings with combined adsorption, osmotic, and necrolytic effects, has shown significant improvements in the effectiveness of purulent wound treatment.

Comparison of clinical characteristics and outcomes between COVID-19 survivors and non-survivors: a retrospective observational study

Background To compare the clinical characteristics of COVID-19 survivors and non-survivors who were transferred from general wards to the critical care units in four tertiary hospitals of Nepal. Methods This study utilized electronic data from the National Intensive Care Unit (ICU) registry managed by the Nepal Intensive Care Research Foundation (NICRF). A retrospective observational study was conducted among 78 eligible COVID-19 patients admitted to the intensive care units of four different hospitals between 2020 and 2022. The Mann-Whitney U test was used to compare each continuous variable between the survivors and non survivors, while Pearson's chi-squared test was used to examine the association between each categorical variable and outcome. Results Among 78 cases of COVID-19 studied, 29 (37.1%) had died, and 49 (62.8%) had recovered. The median age of the patient was 57.5 years, with a higher percentage of males (66.6%). Hypertension (41%) and diabetes (26.9%) were common comorbidities, whereas pneumonia (41%) and acute respiratory distress syndrome (19.2%) were common complications. Most patients required oxygen therapy (96.2%). Corticosteroids (76.9%) and anticoagulants (83.3%) were commonly administered medications. Median of mean arterial pressure was 85 mm Hg [ IQR- 79.2 - 99.5] in non-survivors and 93.3 mm Hg [IQR- 86.6 - 102.6 ] in survivors which was significantly different between the two groups (p=0.04). Nine of the patients had cardiac dysfunction on ICU admission, of which none survived (p=0.001). Out of ten patients requiring inotropes or vasopressors, only two survived (p=0.001). Conclusions Non-survivor COVID patients had lower mean arterial pressure on admission to intensive care units. A higher proportion of patients with cardiac dysfunction and requiring inotropes or vasopressors could not survive.

Energy and protein nutrition adequacy in general wards among intensive care unit survivors: A systematic review and meta-analysis.

Adequate energy and protein provision is mandatory to optimize survival chances in critical illness, prevent loss of muscle mass, and reduce length of stay. Data are available concerning feeding adequacy in intensive care unit (ICU) participants, but little is known about the adequacy in post-ICU participants. This systematic review aimed to evaluate feeding adequacy in post-ICU participants and addressed causes of feeding interruption leading to suboptimal adequacy. For this systematic review, a bibliographic search was performed in PubMed, Scopus, and Web of Science. Randomized controlled studies, non-randomized controlled studies, and observational studies conducted between January 1990 and November 2023 fulfilling the inclusion criteria were withheld. Eight studies were included. Outcomes reported were energy and protein adequacy, barriers, and feeding routes. Energy and protein requirements were determined in various ways, including indirect calorimetry and standardized and weight-based formulas. Energy adequacy ranged from 52% to 102% and protein adequacy between 63% and 86%. Participants were mainly fed with enteral nutrition (EN) or a combination of oral nutrition and EN. The main barrier reported for inadequate nutrition intake was feeding tube removal. Next to different ways in calculating targets and reporting results, a wide range in energy and protein adequacy was observed, but with constant protein underfeeding. Participants fed with EN or a combination of EN and oral nutrition had the best adequacy; inappropriate tube removal is a common barrier leading to inadequate therapy. Standardized reporting and larger studies are needed to guide nutrition care for post-ICU participants.

An Audit of a Modified Pediatric Early Warning Scoring System in a Tertiary Pediatric Hospital.

Pediatric early warning systems identify patients at risk for deterioration. We aimed to determine if a locally adapted pediatric early warning system [KK hospital early warning score (KEWS)] can distinguish patients who require transfer from general ward to high dependency unit (HDU) or PICU, from those who do not. We conducted a retrospective case-control single-center audit. All unplanned general ward to PICU/HDU transfer from January to December 2021 were included as cases. We collected KEWS at the time of transfer and at 2, 4 and 6 hours prior to transfer. Univariate and multivariable logistic regression with imputation analysis were performed to identify variables associated with unplanned PICU/HDU transfer. There were 784 patients (196 cases and 588 controls). Median age of cases and controls were 3.3 (interquartile range: 1.0-9.7) and 3.9 (0.8-11.3) years, respectively. At the time of transfer, median (interquartile range) KEWS for cases and controls were 3 (0, 4) and 0 (0, 1), respectively (P <.001). At all timepoints, KEWS was able to distinguish between children who did and did not require transfer to HDU/PICU (At time of transfer: area under the curve = 0.80, 95% CI = 0.75-0.85, P <.001). After adjusting for age, category of admission, frequency of ordered monitoring, KEWS predicted HDU/PICU transfer with an odds ratio of 2.34 (95% CI 1.82 to 3.00, P <.001). KEWS was able to distinguish patients requiring transfer from GW to HDU/PICU from those not needing a transfer.

093. A Rare Case of Giant Urethral Stone Removal by Uretrolithotomy in A Patient with Urethral Diverticles

Background: A rare case involving a 54-year-old male who complained of persistent micturition pain for 10 years. The patient experienced urinary incontinence and reported a palpable mass under his testicle. Methods: Clinically, a mass was found in the perineum, and imaging studies using bipolar voiding urethrocystography showed a urethral stricture with urethral stones measuring 4 cm in diameter. Results: The patient underwent urethrolithotomy surgery for urolithiasis. After surgery, the patient was admitted to the general ward for 3 days and then discharged. Panendoscopic and urethrography evaluations revealed no residual stones, and urethral dilation was noted. Conclusion: Urethral stones are rare and may result from calculus migration from the upper urinary tract or structural abnormalities of the urethra. The occurrence of stones within the diverticulum is reported to range from 1% to 10% and often presents with nonspecific symptoms. It is important to evaluate the size and location of the urethral calculus, as well as the underlying urethral pathology.

Sepsis Bundle Compliance and Mortality according to Body Temperature of Patients with Sepsis in General Wards Identified Using the Rapid Response System

Purpose : This study aimed to investigate the difference in compliance with the sepsis bundle and mortality rates according to the body temperature of patients with sepsis in general wards identified using a rapid response system (RRS). Methods : A retrospective observational study of 1,083 patients with sepsis in general wards identified using the RRS from July 2018 to December 2022 was performed at a tertiary care hospital in South Korea. The patients were classified into hypothermia (＜36℃), normothermia (36-38℃), and hyperthermia (＞38℃) groups according to their body temperature at the time of RRS activation. Results : A total of 1,083 sepsis patients were analyzed, comprising 17 cases of hypothermia, 624 cases of normothermia, and 442 cases of hyperthermia. There were statistically significant differences among the body temperature groups in the rate of compliance with the sepsis bundle within 1 h (hypothermia: 64.7% vs. normothermia: 49.5% vs. hyperthermia: 60.4%, &lt;i&gt;p&lt;/i&gt; =.010), the rate of compliance with the overall sepsis bundle, including lactate re-measurement (64.7% vs. 49.5% vs. 60.4%, &lt;i&gt;p&lt;/i&gt; =.001), and the rate of blood culture testing (94.1% vs. 85.9% vs. 92.8%, &lt;i&gt;p&lt;/i&gt; =.002). The 28-day mortality rates in the hypothermia, normothermia, and hyperthermia groups were 29.4%, 32.4%, and 16.5%, respectively (&lt;i&gt;p&lt;/i&gt; ＜.001). Conclusion : There were statistically significant differences in compliance with the sepsis bundle and mortality rates according to body temperature. Patients with sepsis and normothermia showed lower compliance with the sepsis bundle and higher mortality rates. Therefore, it is recommended to develop strategies for the early recognition of patients with sepsis and normothermia and to improve compliance with the sepsis bundle.

A longitudinal observational study on activated partial thromboplastin time in hypothyroidism and effect of thyroxine supplementation

Background: Hypothyroidism is a common condition characterized by thyroid hormone deficiency, which, if untreated, can lead to severe health consequences and even death. Due to the wide range of clinical presentations and non-specific symptoms, hypothyroidism is primarily diagnosed biochemically. It can result from congenital thyroid abnormalities or iodine deficiency. Aims and objectives: Aim: To evaluate the correlation between hypothyroidism and Activated Partial Thromboplastin Time (aPTT) and assess the effect of thyroxine supplementation. Objective: To study the impact of levothyroxine supplementation on aPTT in hypothyroid patients. Materials and methods: This observational study was conducted at the General Medicine outpatient clinic and inpatient wards at Al-Ameen Medical College and Hospital, Vijayapura, from September 2022 to March 2024. A total of 80 hypothyroid patients of both sexes were included. TSH, Free T4, and aPTT levels were measured with appropriate aseptic precautions. Results: The majority of subjects were females (90%), with the highest proportion (31.3%) aged 26-35 years. The mean ± SD of pre-thyroxine TSH was 25.453 ± 19.9073, which significantly decreased to 4.299 ± 0.6738 post-thyroxine. aPTT values also decreased significantly post-treatment. A positive correlation was found between TSH and aPTT, while aPTT had a negative correlation with T3 and T4 levels. Conclusion: aPTT is significantly elevated in hypothyroid patients and shows a positive correlation with TSH levels. Regular monitoring of aPTT should be included in the follow-up of hypothyroid patients.

Interventions and evaluation to improve oral health in patients with stroke: a scoping review

Objectives: This scoping review aimed to identify and analyze intervention strategies and assessment methods for oral hygiene management (OHM) and oral function management (OFM) in patients with stroke admitted to general wards, with the goal of providing directions for future research. Methods: We conducted a comprehensive literature search on studies published over the past 10 years across databases, including Cochrane, Embase, Medline, PubMed, and ProQuest. A total of 18 studies met the inclusion and exclusion criteria. Results: In the OHM studies (N=7), oral hygiene care was primarily provided by nurses, dental assistants, and nursing care aides. Oral hygiene was assessed using plaque and gingival bleeding indices with products such as electronic toothbrushes and mouth rinses. In the OFM studies (N=11), care was provided by speech-language pathologists, occupational therapists, and dental hygienists. Assessment tools included the Functional Oral Intake Scale, the PenetrationAspiration Scale, and Video Fluoroscopic Swallowing Studies. Conclusions: Improving the oral health of patients with stroke requires both hygiene and functional management. Therefore, it is necessary to develop a method that provides specialized oral care tailored to the hospitalization environment and the specific conditions of patients with stroke.

Cardiopulmonary long-term effects 6, 18 and 30 months after severe COVID-19 infection

Abstract Background SARS-CoV-2 infection affects the cardiopulmonary system in both the acute and long-term phase. This study aimed to comprehensively assess symptoms and potential longterm impairments 6, 18 and 30 months in patients previously hospitalized for severe Covid-19 infection. Methods This prospective registry included patients hospitalized for PCR-confirmed Covid-19 infection. Approximately 6 months post-discharge, follow-up examination included patient history, clinical examination, echocardiography, electrocardiogram, cardiac magnetic resonance imaging (cMRI), chest computed tomography (CT) scan, pulmonary function test (PFT), six-minute walk test (6MWT) and a comprehensive laboratory panel. Patients with pathologic findings during the first visit underwent a second (at 18 months) and third (at 30 months) follow-up examination. Those without pathologic findings or who refused further medical examinations were contacted via phone to inquire about symptoms. Results Between July 2020 and April 2022, 200 patients (91% general ward, 9% intensive care unit) were recruited. Due to dropouts, the second visit was conducted in 170 patients and the third visit in 139 (74 in person, 65 via telephone). Long Covid criteria were fulfilled by 73% at 6 months, 52% at 18 months and 49% at 30 months post-discharge, with fatigue being the most common symptom (Figure 1). Echocardiography at 6 months showed impaired left ventricular function in 15 patients, with normalization in 80% at 18 months and further 66% at 30 months (Figure 2). cMRI revealed pericardial effusions in 28 patients at 6 months, which resolved in 47% at 18 months and in further 60% at 30 months. Signs of peri- or myocarditis were present in 7 patients at 6 months and were resolved in all 4 patients who attended control studies at 18 months. PFT at 6 months detected reduced vital capacity in 17 patients, of whom 10% returned to normal at 18 months and a further 66% showed normalization at 30 months. Chest CT scans at 6 months identified post-infectious residues in 41 patients, with full recovery in 20% at 18 months without further normalization after 30 months. The length of in-hospital stay was identified as a significant predictor for persisting Long Covid 6 months after discharge (95% CI: 1.005 - 1.12, p=0.03). No predictors have been found for Long Covid at 18 and 30 months. Conclusion While the prevalence of Long Covid decreased over time, a significant symptom burden persisted at 6, 18 and even 30 months after severe Covid-19 infection. Structural and functional abnormalities were less frequent compared to reported symptoms, posing a challenge in substantiating the causes of these symptoms.

Time to detection of serious adverse events by continuous vital sign monitoring versus clinical practice.

Continuous vital sign monitoring detects far more severe vital sign deviations (SVDs) than intermittent clinical rounds, and deviations are to some extent related to subsequent serious adverse events (SAEs). Early detection of SAEs is pivotal to allow for effective interventions but the time relationship between detection of SAEs by continuous vital sign monitoring versus clinical practice is not well-described at the general ward. To quantify the time difference between detection of SAEs by continuous vital sign monitoring and clinical suspicion of deterioration (CSD) in major abdominal surgery patients. Five hundred and five patients had their vital signs continuously monitored in combination with usual clinical practice consisting of National Early Warning Score assessments at least every 8'th hour, assessments during rounds, and other kinds of staff-patient interactions. The primary outcome was the time difference between the first chart note of CSD versus the first SVD, detected by continuous vital sign monitoring, in patients with a subsequent confirmed SAE during or up to 48 h after end of continuous vital sign monitoring. Out of the 505 continuously monitored patients, 142 patients had a combination of both postoperative SAE, CSD and SVD, and thus were included in the primary analysis. The median time from the first SVD to SAE was 42.8 h (interquartile range 19.8-72.1 h) compared to 13 minutes (interquartile range - 4.8 to 3.5 h) for CSD with a median difference of 48.1 h (95% confidence interval 43.0-54.8 h), p-value < .001. Continuous vital sign monitoring detects signs of oncoming SAEs in the form of SVD hours before CSD, potentially allowing for earlier and more effective treatments to reduce the extent of SAEs.

Valve unit instead of intensive care unit admission after transcatheter edge-to-edge tricuspid valve repair

Abstract Background Standardization of periprocedural pathways reduces the length of hospital stay and thus healthcare costs and increases patient safety. Post-procedure admission to the intensive care unit (ICU) after transcatheter edge-to-edge tricuspid valve repair (T-TEER) has been the standard of care. Due to the COVID-19 pandemic related decline in high-care hospital beds, our center established primary admission to a dedicated general cardiologic care ward, the valve unit (VU). Aim To assess benefits and risks of admission to the VU instead of ICU after T-TEER. Methods This retrospective observational study included 270 consecutive patients who underwent T-TEER between March 2017 and June 2023 at our university hospital. Patients were admitted to the ICU post-procedure up to April 9th 2020 as standard (ICU-group, n = 53). Subsequent patients were planned for admission to a dedicated VU (VU-group, n = 217). We compared the groups and assessed length of hospital stay and in-hospital complications. In the VU-group, we examined unplanned transfer to the ICU (cross-over) and its predictors. Results Monitoring at the VU included continuous telemetric ECG-recording, oxygen saturation assessment, periodical blood pressure measurements and 24-hours physician presence. In contrast to the ICU, only non-invasive blood pressure measurements, less frequent laboratory controls and less intense fluid monitoring took place. The postinterventional hospital stay of patients with planned VU admission was significantly shorter compared to patients with planned ICU admission (median 4 (interquartile range (IQR) 3 - 5) vs. 4 (IQR 4 - 5) days, p = 0.030). Remarkably, overall complication rates were low and cardiogenic shock, infections, bleeding, vascular complications, delirium and acute kidney injury requiring dialysis were similar in both groups. 37 patients that were planned for VU had to cross over to unplanned ICU admission (17.1 %). Patients that had crossed over to unplanned ICU treatment had significantly higher risk for acute kidney injury (20.0 vs. 10.0%, p = 0.039) and in-hospital mortality (5.6 vs. 0%, p = 0.045). Higher systolic pulmonary artery pressure (sPAP) (OR 1.048, 95 %-CI 1.015 – 1.082, p = 0.003), NYHA functional class &amp;gt;= III (OR 9.176, 95 % CI 1.141 – 74.396, p = 0.037), and pre-interventional tricuspid regurgitation (TR) grade V (OR 2.941, 95 % CI 1.089 – 7.970, p = 0.033) were found to independently predict cross-over to unplanned ICU treatment. Conclusion Postinterventional admission to the VU instead of ICU after T-TEER shortens postprocedural hospital stay. A small proportion of had an unplanned transfer to ICU, which was accompanied by slightly higher complication rates. This cross-over affects patients with more advanced disease indicated by high pulmonary pressures, NYHA class and TR grade. Thus, admission to a valve unit is favorable for most patients after T-TEER, but those with advanced disease should be monitored more closely.

Best Evidence Summary for the Prevention of Pressure Injuries in Orthopaedic Patients.

To systematically search, evaluate and synthesise the most robust evidence regarding pressure injury prevention in orthopaedic patients admitted to general wards. The present study provides an evidence-based summary of the most robust findings, adhering to the evidence guidelines established by the Center for Evidence-Based Nursing of Fudan University. According to the "6S" model, a systematic search was conducted for literature on pressure injury prevention among orthopaedic patients in general wards. The types of literature included guidelines, clinical decisions, expert Consensus, evidence summaries, etc. The search period covered the time from the beginning of the database up to December 2023. The following databases and resources were systematically searched: Up To Date, JBI, NICE, WOCN, NZWCS, etc. RESULTS: Fifteen literature sources were included, comprising one clinical decision, eight guidelines, one systematic review, and one expert Consensus. In these sources, a comprehensive collection of 34 pieces of best evidence was formed across six key topics: risk assessment, position management, skin care, device used for device-related pressure injury, nutritional assessment, and support, as well as health education and training. Among the evidence gathered, a strong recommendation was made for 18 pieces, while the remaining 16 received a weak recommendation. This study provides a comprehensive synthesis of the most robust evidence on pressure injury prevention in orthopaedic patients, encompassing 34 pieces of evidence that can serve as valuable references for clinical practice. Before implementing this evidence, it is crucial to evaluate the specific contextual factors within different countries and medical institutions, as well as the facilitators and barriers influencing its application by healthcare professionals and patient's preferences. Furthermore, targeted evidence selection should be conducted through careful screening and subsequent adjustments in implementation, thereby offering a more scientifically grounded basis for clinical nursing practice. Future research endeavours should prioritise investigating strategies for effective evidence utilisation. The prevention of pressure injuries poses a significant challenge for orthopaedic patients. This study presents a synthesis of 34 pieces of best evidence to provide guidance on preventive measures for pressure injuries in orthopaedic patients. Adhering to and implementing these 34 pieces of evidence can effectively aid in preventing pressure injuries in clinical practice. This evidence encompasses risk assessment, position management, skin care, device usage for device-related pressure injuries, nutritional support and evaluation, and health education and training, establishing a comprehensive and systematic implementation process. Assessing the risk of pressure injuries during interventions serves as an essential prerequisite for developing effective strategies to prevent such injuries among orthopaedic patients. Ultimately, this study will offer valuable guidance to healthcare professionals worldwide regarding preventing pressure injuries in orthopaedic patients. Upon admission to the hospital, it is essential to conduct a risk assessment and implement evidence-based, individualised prevention measures for pressure ulcers in patients to prevent their occurrence. This study will provide valuable insights into preventing pressure injuries in orthopaedic patients admitted to orthopaedic wards for healthcare workers worldwide.

Impact of Remote Dielectric Sensing on Predicting Worsening Heart Failure During Hospitalization for Heart Failure.

Background: A remote dielectric sensing (ReDS) system quickly quantifies pulmonary congestion. Nonetheless, its efficacy in predicting an in-hospital increase in plasma B-type natriuretic peptide levels, the potential surrogate of worsening heart failure, remains undetermined. Methods: Patients who underwent ReDS measurement on admission during their hospitalization in the general wards for heart failure between 2021 and 2022 were eligible. The impact of the baseline ReDS value, completely blinded to the attending clinicians, on the in-hospital increase in plasma B-type natriuretic peptide levels of >100 pg/mL from index admission was evaluated. Results: A total of 147 patients admitted with acute-on-chronic heart failure (median age: 79 years; 76 men) were included. The median ReDS value on admission was 28% (25%, 34%). Eighteen patients experienced the primary outcome: plasma B-type natriuretic peptide levels increasing from 461 (207, 790) pg/mL (baseline) to 958 (584, 1290) pg/mL (maximum) (p < 0.001). The ReDS value on admission was an independent predictor of the primary outcome, with an adjusted odds ratio of 1.07 (95% confidence interval: 1.01-1.14; p = 0.028) with an optimal cutoff of 32%. Conclusions: The ReDS system could be a promising tool for predicting in-hospital worsening heart failure in patients hospitalized for heart failure when measured upon admission. The clinical implication of ReDS-guided management of heart failure during index hospitalization requires further studies.

Effect of different doses of esketamine on the median effective concentration of propofol for inhibiting body movement during hysteroscopy

The objective of this study is to investigate the effects of various doses of esketamine on the median effective concentration (EC50) of propofol required for inhibiting body movement during hysteroscopy. Additionally, this research aims to explore the pharmacodynamic interactions between esketamine and propofol. Prospective, double-blind, up-down sequential allocation study. Operating room, post-anesthesia care unit (PACU), and general ward. A total of 90 patients were allocated into three groups in a randomized, double-blinded manner as follows: 0.1 mg/kg esketamine combined with propofol intravenous injection (EP0.1) group, 0.2 mg/kg esketamine combined with propofol intravenous injection (EP0.2) group, 0.3 mg/kg esketamine combined with propofol of intravenous injection (EP0.3) group. For the initial patient in each group, the starting effector target concentration of propofol was set at 4 µg/ml. Each patient received an initial intravenous injection of 0.04 mg/kg midazolam, followed by the administration of the appropriate dose of esketamine. Ten seconds after the esketamine injection, propofol was administered intravenously to achieve the target concentration. In accordance with the sequential method principle, the concentration of propofol for the subsequent patient was adjusted based on the response of the previous patient. Effective inhibition of body movement was defined as the absence of any involuntary body movements throughout the entire surgical process. If the previous patient exhibited body movements, the propofol concentration for the next patient was increased by 0.5 µg/ml; conversely, if no movements were observed, it was decreased by 0.5 µg/ml. The up-down sequential allocation method and probit regression were used to calculate the EC50 of propofol. Hospital Anxiety and Depression Scale-Anxiety (HADS-A) and Depression (HADS-D) score, adverse events, hemodynamic changes, demographic data and clinical characteristics. The EC50 of propofol was 3.849 μg/ml (95% CI: 3.419–4.281) in the EP0.1 group, 3.641 μg/ml (95% CI: 2.807−4.200) in the EP0.2 group, and 3.417 μg/ml (95% CI: 2.845–3.852) in the EP0.3 group. These findings suggest that esketamine can dose-dependently reduce the EC50 of propofol. Esketamine can dose-dependently reduce the EC50 of propofol in hysteroscopy, while concurrently lowering patients’ HADS-A and HADS-D scores 24 h post-operation. It is concluded that the optimal dose of esketamine, when combined with propofol for hysteroscopy, is 0.3 mg/kg.
