Importância da assistência odontológica dentro do ambiente hospitalar / Importance of dental care within the hospital enviroment

A assistência odontológica é imprescindível para a prevenção de doenças infecciosas e para a manutenção da integridade da cavidade oral de pacientes internatos em unidades de terapia intensiva. O objetivo deste estudo foi avaliar o conhecimento e as práticas de higiene oral dos acadêmicos do curso de Enfermagem de uma instituição de ensino superior, que realizam estágio em hospital, no controle de higiene bucal de pacientes internados em ambiente hospitalar. Participaram do estudo 40 alunos, que responderam 14 perguntas com o intuito de avaliar o conhecimento e as práticas no controle de higiene bucal, realizadas por eles, em pacientes internados em ambiente hospitalar. Os resultados demonstraram que os acadêmicos entrevistados tinham idade média de 25,8 anos, sendo 95% do sexo feminino e apenas 5% do sexo masculino. Destes, 42,5% afirmaram não haver presença de um Cirurgião-Dentista em ambiente hospitalar e 82,5% responderam que o responsável pela saúde bucal dos pacientes é do técnico de enfermagem. Quanto aos cuidados em pacientes internados em UTI, 52,5% dos entrevistados relataram que estes pacientes recebem higienização bucal, porém 30% alegaram que esta pratica não era realizada e 17,5% não sabiam responder. Além disso, 47,5% dos entrevistados afirmam ter insegurança ao realizar os procedimentos de higiene bucal dos pacientes. Pode-se concluir que os acadêmicos entrevistados possuem bom conhecimento acerca da importância dos cuidados com a saúde bucal dos pacientes internados em ambiente hospitalar. No entanto, ainda existem muitas dúvidas relacionadas ao manejo clínico de procedimentos de promoção de saúde bucal, que poderiam ser solucionados com a presença de um profissional de Odontologia inserido em uma equipe multidisciplinar(AU)

Oral care is essential for the prevention of infectious diseases and for maintaining the integrity of the oral cavity of patients hospitalized in intensive care units. The objective of this study is to evaluate the knowledge and oral hygiene practices of Nursing students at a higher education institution, who carry out internships in a hospital, in controlling the oral hygiene of patients admitted to a hospital environment. 40 students participated in the study, who answered 14 questions with the aim of evaluating the knowledge and practices in controlling oral hygiene, carried out by them, on patients hospitalized in a hospital environment. The results demonstrated that the academics interviewed had an average age of 25.8 years, with 95% being female and only 5% being male. Of these, 42.5% stated that there was no presence of a Dental Surgeon in a hospital environment and 82.5% responded that the nursing technician is responsible for the patients' oral health. Regarding care for patients admitted to the ICU, 52.5% of those interviewed reported that these patients receive oral hygiene, however 30% claimed that this practice was not performed and 17.5% did not know how to answer. Furthermore, 47.5% of those interviewed say they are insecure when carrying out oral hygiene procedures for patients. It can be concluded that the academics interviewed have good knowledge about the importance of oral health care for patients hospitalized in a hospital environment. However, there are still many doubts related to the clinical management of oral health promotion procedures, which could be resolved with the presence of a dentistry professional within a multidisciplinary team(AU)

Risk factors for bloodstream infection among patients admitted to an intensive care unit of a tertiary hospital of Shanghai, China.

Blood flow infections (BSIs) is common occurrences in intensive care units (ICUs) and are associated with poor prognosis. The study aims to identify risk factors and assess mortality among BSI patients admitted to the ICU at Shanghai Ruijin hospital north from January 2022 to June 2023. Additionally, it seeks to present the latest microbiological isolates and their antimicrobial susceptibility. Independent risk factors for BSI and mortality were determined using the multivariable logistic regression model. The study found that the latest incidence rate of BSI was 10.11%, the mortality rate was 35.21% and the mean age of patients with BSI was 74 years old. Klebsiella pneumoniae was the predominant bacterial isolate. Logistic multiple regression revealed that tracheotomy, tigecycline, gastrointestinal bleeding, shock, length of hospital stay, age and laboratory indicators (such as procalcitonine and hemoglobin) were independent risk factors for BSI. Given the elevated risk associated with use of tracheotomy and tigecycline, it underscores the importance of the importance of cautious application of tracheostomy and empirical antibiotic management strategies. Meanwhile, the independent risk factors of mortality included cardiovascular disease, length of hospital stay, mean platelet volume (MPV), uric acid levels and ventilator. BSI patients exhibited a significant decrease in platelet count, and MPV emerged as an independent factor of mortality among them. Therefore, continuous monitoring of platelet-related parameters may aid in promptly identifying high-risk patients and assessing prognosis. Moreover, monitoring changes in uric acid levels may serve as an additional tool for prognostic evaluation in BSI patients.

Development and external validation of a machine learning model for the prediction of persistent acute kidney injury stage 3 in multi-centric, multi-national intensive care cohorts.

BACKGROUND: The aim of this retrospective cohort study was to develop and validate on multiple international datasets a real-time machine learning model able to accurately predict persistent acute kidney injury (AKI) in the intensive care unit (ICU). METHODS: We selected adult patients admitted to ICU classified as AKI stage 2 or 3 as defined by the "Kidney Disease: Improving Global Outcomes" criteria. The primary endpoint was the ability to predict AKI stage 3 lasting for at least 72 h while in the ICU. An explainable tree regressor was trained and calibrated on two tertiary, urban, academic, single-center databases and externally validated on two multi-centers databases. RESULTS: A total of 7759 ICU patients were enrolled for analysis. The incidence of persistent stage 3 AKI varied from 11 to 6% in the development and internal validation cohorts, respectively and 19% in external validation cohorts. The model achieved area under the receiver operating characteristic curve of 0.94 (95% CI 0.92-0.95) in the US external validation cohort and 0.85 (95% CI 0.83-0.88) in the Italian external validation cohort. CONCLUSIONS: A machine learning approach fed with the proper data pipeline can accurately predict onset of Persistent AKI Stage 3 during ICU patient stay in retrospective, multi-centric and international datasets. This model has the potential to improve management of AKI episodes in ICU if implemented in clinical practice.

The frequency of sepsis-associated delirium in intensive care unit and its effect on nurse workload.

AIM: To determine the frequency of sepsis-associated delirium (SAD) in the intensive care unit and its effect on nurse workload. DESIGN: A cross-sectional and correlational design was used. METHODS: The study was conducted with 158 patients in the adult intensive care unit of a hospital between October 28 and July 28, 2022. Data analysis included frequency, chi-squared/fisher's exact test, independent samples t-test, correlation analysis, simple and multiple linear regression analyses. The study adhered to the STROBE guidelines. RESULTS: Sepsis was detected in 12.7% of the patients, delirium in 39.9%, and SAD in 10.1%. SAD was more common in males (19%) and 56.3% of the patients were admitted to the unit from the emergency department. Patients developing SAD had significantly higher age and mean sequential organ failure evaluation, acute physiology and chronic health evaluation II, and C-reactive protein and lactate scores, but their Glasgow Coma Scale scores were significantly low. There was a moderate positive relationship between the patients' Sequential Organ Failure Assessment score and the presence of SAD. The most common source of infection in patients diagnosed with SAD was bloodstream infection (44.4%). SAD significantly increased nurse workload and average care time (1.8 h) and it explained 22.8% of the total variance in nurse workload. Additionally, the use of antibiotics, vasopressors and invasive mechanical ventilation significantly increased nurse workload. CONCLUSION: In the study, in patients who developed SAD increased nurse workload and average care time significantly. Preventive nursing approaches and effective management of SAD can reduce the rate of development of SAD and nurse workload. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: It is important to work with routine screening, prevention and patient-nurse ratio appropriate to the workload for SAD.

Interventions for Pulmonary Vein Stenosis.

Pulmonary vein stenosis (PVS) is a rare and unique disease of infants and young children. PVS is attended by high morbidity and mortality, and for many decades, effective therapy eluded the practitioner. However, in the most recent era, interventional techniques when employed in combination with systemic (primary) therapy have had a remarkable impact on outcomes in these at-risk children. Despite apparent complete relief of PVS in a discrete region of a pulmonary vein, stenosis reliably recurs and progresses. In this review, we discuss the current state-of-the-art interventional techniques, through the lens of our collective experiences and practices.

Patients' and relatives' experiences of cognitive impairment following an intensive care unit admission. A qualitative study.

BACKGROUND: Cognitive impairment poses a significant challenge following critical illness in the intensive care unit. A knowledge gap exists concerning how patients experience cognitive impairments. OBJECTIVES: The aim was to explore patients' and relatives' experiences of patients' cognitive impairment due to critical illness following an intensive care unit admission. METHODS: A qualitative multicentre study was conducted in Denmark with 3- and 6-month follow-ups using single and dyadic interviews. A phenomenological hermeneutic approach was adopted using a Ricoeur-inspired textual in-depth analysis method. The Consolidated Criteria for Reporting Qualitative Research checklist was used. RESULTS: Three themes emerged from interviews with 18 patients and 14 relatives: 'It feels like living in a parallel world', 'Getting back to a normal everyday life with a vulnerable self', and 'Managing everyday life using self-invented strategies'. Patients used self-invented strategies to manage their vulnerability and newly acquired cognitive impairments when no help or support was provided specifically targeting their cognitive impairments. Not being as cognitively capable as they previously had been turned their lives upside down. Losing control and not being themselves made them vulnerable. Patients did not want to burden others. However, support from relatives was invaluable in their recovery and rehabilitation. CONCLUSIONS: Patients experienced multiple cognitive impairments affecting their adaption to everyday life. They strove to overcome their vulnerability using a variety of self-invented strategies and activities.

Exploring the Optimal Range of Central Venous Pressure in Sepsis and Septic Shock Patients: A Retrospective Study in 208 Hospitals.

BACKGROUND: The aim of this study was to investigate the optimal CVP range in sepsis and septic shock patients admitted to intensive care unit. METHODS: We performed a retrospective study with adult sepsis patients with CVP records based on the eICU Collaborative Research Database. Multivariable logistic regression was performed to explore the associations between CVP level and hospital mortality. Non-linear correlations and optimal CVP range were explored using restricted cubic splines (RCS). RESULTS: 5302 sepsis patients were included in this study. Patients in 4-8 mmHg group owned the lowest odds ratio for raw hospital mortality (19.7%). The logistic regression analyses revealed that hospital death risk increased significantly when mean CVP level exceeds 12 mmHg compared to 4-8 mmHg level. U-shaped association of CVP with hospital mortality was revealed by RCS model in septic shock patients and the optimal range was 5.6-12 mmHg. While, there was a J-shaped trend for non-septic shock patients. For non-septic shock patients, patients had an increased risk of hospital death only if CVP exceeded 11 mmHg. CONCLUSIONS: We observed U-shaped association between mean CVP level and hospital mortality in septic shock patients and J-shaped association in non-septic shock patients. This may imply that patients with different severity of sepsis have different CVP requirements. We need to monitor and manage CVP according to the circulatory status of the sepsis patient.

Ultrasound-derived rates of muscle wasting in the intensive care unit and in the post-intensive care ward for patients with critical illness: Post hoc analysis of an international, multicentre randomised controlled trial of early rehabilitation.

BACKGROUND AND AIMS: Muscle wasting results in weakness for patients with critical illness. We aim to explore ultrasound-derived rates of change in skeletal muscle in the intensive care unit (ICU) and following discharge to the post-ICU ward. DESIGN: Post hoc analysis of a multicentre randomised controlled trial of functional-electrical stimulated cycling, recumbent cycling, and usual care delivered in intensive care. METHOD: Participants underwent ultrasound assessment of rectus femoris at ICU admission, weekly in the ICU, upon awakening, ICU discharge, and hospital discharge. The primary outcome was rate of change in rectus femoris cross-sectional area (ΔRFCSA) in mm2/day in the ICU (enrolment to ICU discharge) and in the post-ICU ward (ICU discharge to hospital discharge). Secondary outcomes included rate of change in echo intensity (ΔEI), standard deviation of echo intensity (ΔEISD), and the intervention effect on ultrasound measures. Echo intensity is a quantitative assessment of muscle quality. Elevated echo intensity may indicate fluid infiltration, adipose tissue, and reduced muscle quality. RESULTS: 154 participants were included (mean age: 58 ± 15 years, 34% female). Rectus femoris cross-sectional area declined in the ICU (-4 mm2/day [95% confidence interval {CI}: -9 to 1]) and declined further in the ward (-9 mm2/day [95% CI: -14 to -3]) with a mean difference between ICU and ward of -5 mm2/day ([95% CI: -2, to 11]; p = 0.1396). There was a nonsignificant difference in ΔEI between in-ICU and the post-ICU ward of 1.2 ([95% CI: -0.1 to 2.6]; p = 0.0755), a statistically significant difference in ΔEISD between in-ICU and in the post-ICU ward of 1.0 ([95% CI, 0.5 to 1.5]; p = 0.0003), and no difference in rate of change in rectus femoris cross-sectional area between groups in intensive care (p = 0.411) or at hospital discharge (p = 0.1309). CONCLUSIONS: Muscle wasting occurs in critical illness throughout the hospital admission. The average rate of loss in muscle cross-sectional area does not slow after ICU discharge, even with active rehabilitation.

Phenotypic clustering of patients hospitalized in intensive cardiac care units: Insights from the ADDICT-ICCU study.

BACKGROUND: Intensive cardiac care units (ICCUs) were created to manage ventricular arrhythmias after acute coronary syndromes, but have diversified to include a more heterogeneous population, the characteristics of which are not well depicted by conventional methods. AIMS: To identify ICCU patient subgroups by phenotypic unsupervised clustering integrating clinical, biological, and echocardiographic data to reveal pathophysiological differences. METHODS: During 7-22 April 2021, we recruited all consecutive patients admitted to ICCUs in 39 centers. The primary outcome was in-hospital major adverse events (MAEs; death, resuscitated cardiac arrest or cardiogenic shock). A cluster analysis was performed using a Kamila algorithm. RESULTS: Of 1499 patients admitted to the ICCU (69.6% male, mean age 63.3±14.9 years), 67 (4.5%) experienced MAEs. Four phenogroups were identified: PG1 (n=535), typically patients with non-ST-segment elevation myocardial infarction; PG2 (n=444), younger smokers with ST-segment elevation myocardial infarction; PG3 (n=273), elderly patients with heart failure with preserved ejection fraction and conduction disturbances; PG4 (n=247), patients with acute heart failure with reduced ejection fraction. Compared to PG1, multivariable analysis revealed a higher risk of MAEs in PG2 (odds ratio [OR] 3.13, 95% confidence interval [CI] 1.16-10.0) and PG3 (OR 3.16, 95% CI 1.02-10.8), with the highest risk in PG4 (OR 20.5, 95% CI 8.7-60.8) (all P<0.05). CONCLUSIONS: Cluster analysis of clinical, biological, and echocardiographic variables identified four phenogroups of patients admitted to the ICCU that were associated with distinct prognostic profiles. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05063097.

Sustainability of the Subspecialty of Anesthesiology Critical Care: An Expert Consensus and Review of the Literature.

While considerable literature exists with respect to clinical aspects of critical care anesthesiology (CCA) practice, few publications have focused on how anesthesiology-based critical care practices are organized and the challenges associated with the administration and management of anesthesiology critical care units. Currently, numerous challenges are affecting the sustainability of CCA practice, including decreased applications to fellowship positions and decreased reimbursement for critical care work. This review describes what is known about the subspecialty of CCA and leverages the experience of administrative leaders in adult critical care anesthesiologists in the United States to describe potential solutions.

Platelet transfusions in adult ICU patients with thrombocytopenia: A sub-study of the PLOT-ICU inception cohort study.

BACKGROUND: Platelet transfusions are frequently used in the intensive care unit (ICU), but current practices including used product types, volumes, doses and effects are unknown. STUDY DESIGN AND METHODS: Sub-study of the inception cohort study 'Thrombocytopenia and Platelet Transfusions in the ICU (PLOT-ICU)', including acutely admitted, adult ICU patients with thrombocytopenia (platelet count <150 × 109/L). The primary outcome was the number of patients receiving platelet transfusion in ICU by product type. Secondary outcomes included platelet transfusion details, platelet increments, bleeding, other transfusions and mortality. RESULTS: Amongst 504 patients with thrombocytopenia from 43 hospitals in 10 countries in Europe and the United States, 20.8% received 565 platelet transfusions; 61.0% received pooled products, 21.9% received apheresis products and 17.1% received both with a median of 2 (interquartile range 1-4) days from admission to first transfusion. The median volume per transfusion was 253 mL (180-308 mL) and pooled products accounted for 59.1% of transfusions, however, this varied across countries. Most centres (73.8%) used fixed dosing (medians ranging from 2.0 to 3.5 × 1011 platelets/transfusion) whilst some (mainly in France) used weight-based dosing (ranging from 0.5 to 0.7 × 1011 platelets per 10 kg body weight). The median platelet count increment for a single prophylactic platelet transfusion was 2 (-1 to 8) × 109/L. Outcomes of patients with thrombocytopenia who did and did not receive platelet transfusions varied. CONCLUSIONS: Among acutely admitted, adult ICU patients with thrombocytopenia, 20.8% received platelet transfusions in ICU of whom most received pooled products, but considerable variation was observed in product type, volumes and doses across countries. Prophylactic platelet transfusions were associated with limited increases in platelet counts.

A Nationwide Online Tracking System of pediatric ICU demand and capacity during a respiratory epidemic in Uruguay / Desarrollo de un Sistema Nacional de Monitoreo En Línea de Capacidad y Demanda de las Unidades de Cuidados Intensivos Pediátricas Durante Una Epidemia Respiratoria

Monitoring national capacity of pediatric intensive care (PICU) beds is important for resource allocation. We describe the development and application of an online tool for bed occupancy monitoring during the respiratory epidemic of 2023 in Uruguay. A 5-minute survey was sent out daily to each PICU designated staff utilizing an instant messaging application, throughout the 12-week of 2023 winter season. The survey gathered information on staffed bed capacity, occupancy rates, invasive mechanical ventilation (IMV) demand and number of children admitted for lower respiratory tract infections (LRTIs). Data was manually entered using the REDcap Software platform. A comparison between PICUs from the capital city Montevideo (MVD) and the inland region (INN) was performed. Participating PICUs had access to a daily dashboard with nationwide data. We collected data from 100% (n=20) of Uruguayan PICUs, 68% in MVD (2.72 PICU beds per-10,000 <18 years) and 32% in the INN (0.86 PICU beds per-10,000 <18 years). National average bed occupancy rate was 55.5%, without differences between MVD and INN. However, LRTI admissions and IMV incidence were notably higher among INN PICUs compared with MVD PICUs, 83.0% vs. 71% (P<0.01) and 19.9% vs. 14.7% (P<0.01) respectively. During one week occupancy exceeded 80% without differences between MVD and INN. The implementation of a nationwide PICU bed monitoring tool was possible. Although occupancy rates did not reach critical levels at a national grade, regional differences were found that merit further study to improve vital PICUs resource allocation.

Monitorear la capacidad nacional de camas de cuidados intensivos pediátricos (UCIP) es importante para la asignación de recursos. Describimos el desarrollo y aplicación de una herramienta online para el seguimiento de la ocupación de camas durante la epidemia respiratoria de 2023 en Uruguay. Se envió diariamente una encuesta de 5 minutos a cada personal designado de la UCIP mediante una aplicación de mensajería instantánea, durante las 12 semanas de la temporada de invierno de 2023. La encuesta recopiló información sobre la capacidad de camas con personal, las tasas de ocupación, la demanda de ventilación mecánica invasiva (IMV) y el número de niños admitidos por infecciones del tracto respiratorio inferior (LRTI). Los datos se ingresaron manualmente utilizando la plataforma del software REDcap. Se realizó una comparación entre UCIP de la capital Montevideo (MVD) y del interior (INN). Las UCIP participantes tuvieron acceso a un panel diario con datos a nivel nacional. Se recolectaron datos del 100% (n=20) de las UCIP uruguayas, el 68% en MVD (2,72 camas UCIP por 10.000 <18 años) y el 32% en el INN (0,86 camas UCIP por 10.000 <18 años). La tasa de ocupación de camas promedio nacional fue del 55,5%, sin diferencias entre MVD e INN. Sin embargo, los ingresos por LRTI y la incidencia de IMV fueron notablemente mayores entre las UCIP INN en comparación con las UCIP MVD, 83,0% frente a 71% (P<0,01) y 19,9% frente a 14,7% (P<0,01), respectivamente. Durante una semana la ocupación superó el 80% sin diferencias entre MVD y INN. Fue posible implementar una herramienta de monitoreo de camas UCIP a nivel nacional. Aunque las tasas de ocupación no alcanzaron niveles críticos a nivel nacional, se encontraron diferencias regionales que merecen más estudios para mejorar la asignación de recursos vitales de las UCIP.

Effects of essential amino acid (EAA) and glutamine supplementation on skeletal muscle wasting in acute, subacute, and postacute conditions.

Under optimal physiological conditions, muscle mass maintenance is ensured by dietary protein, which balances the amino acid loss during the post-absorption period and preserves the body's protein homeostasis. Conversely, in critical clinical conditions (acute, subacute or postacute), particularly those related to hypomobility or immobility, combined with malnutrition, and local/systemic inflammation, the loss of muscle mass and strength can be quantitatively significant. A decline of more than 1% in muscle mass and of more than 3% in muscle strength has been registered in subjects with aged 20-37 yr after just five days of bed rest, similarly to those observed during one year of age-related decline in individuals over the age of 50. Loss of muscle mass and strength can have a dramatic effect on subjects' functional capacities, on their systemic metabolic control and on the amino acid reserve function, all of which are fundamental for the maintenance of other organs' and tissues' cell processes. References available indicate that the average 1%-2% reduction per day of muscle mass in patients in the intensive care unit (ICU) could represent an independent predictor of hospital mortality and physical disability in the five years following hospitalization. After just a few days or weeks of administration, supplementation with EAAs and glutamine has shown significant effects in maintaining muscle size and strength, which are typically negatively affected by some acute/subacute or postacute critical conditions (muscle recovery after surgery, oncology patients, ICU treatments), especially in the elderly or in those with pre-existing degenerative diseases. In this review, we focused on the theoretical bases and the most relevant clinical studies of EAA and glutamine supplementation as a single compound, with the aim of clarifying whether their combined use in a blend (EAAs-glutamine) could be potentially synergistic to prevent disease-related muscle wasting and its impact on the duration and quality of patients' clinical course.

Discharge preparation experiences and needs of intergenerational caregivers of neonatal intensive care unit preterm: A qualitative study.

PURPOSE: This study aimed to explore the real experiences and needs of neonatal intensive care unit (NICU) preterm intergenerational caregivers for discharge preparation and provide a basis for nursing staff to formulate systemic and personalized health education plans and continuous nursing plans for preterm discharge. DESIGN AND METHODS: This was a descriptive qualitative study. An objective sampling method was used to select 16 intergenerational caregivers of preterm infants admitted to the NICU of tertiary obstetrics and gynecology hospitals in Zhejiang and Jilin provinces from December 2023 to February 2024. Semi-structured interviews were conducted on the day of discharge of the preterm infants and six weeks after discharge. Colaizzi's seven-step analysis method was used to analyze the interview data. RESULTS: Based on the existence, relatedness, and growth (ERG) theory, the discharge preparation experiences and needs of neonatal intergenerational caregivers in the NICU were summarized into three themes: psychological condition, care capacity condition, and multi-party support needs. CONCLUSIONS: In the process of hospital discharge preparation, intergenerational caregivers of premature infants in NICU have multiple needs, including enhancing nursing ability and obtaining psychological and multi-party support. It is helpful to take effective interventions to improve their readiness for discharge. PRACTICE IMPLICATIONS: The nursing staff should develop personalized discharge health education plans and continuous nursing plans to improve the level of discharge preparation. PATIENT OR PUBLIC CONTRIBUTIONS: There were no patient or public contributions.

Predictive Factors for Recurrent Hemoptysis After Bronchial Artery Embolization in Patients with Lung Cancer.

PURPOSE: Severe hemoptysis (SH) in lung cancer patients admitted to the intensive care unit (ICU) treated with bronchial artery embolization (BAE) is associated with a high risk of recurrent hemoptysis. The purpose of this study was to identify clinical, radiological and angiographic characteristics associated with recurrent hemoptysis MATERIALS AND METHODS: 144 consecutive lung cancer patients who underwent BAE for life-threatening hemoptysis admitted in the ICU between 2014 and 2022 were retrospectively included. Demographics, laboratory values, clinical course, and radiological/angiographic features were compared between those with and without recurrent hemoptysis within one-month post-embolization. RESULTS: Of the 144 patients (mean age of 60.2 ± 10.9 years, 15.3% females), 34.7% (50/144) experienced significant recurrent hemoptysis within one month, among them 29/50 (58.0%) necessitated a second embolization. Massive hemoptysis was observed in 54.2%, with 16.7% receiving Terlipressin. The mean volume of hemoptysis and SAPS 2 score were 235 ± 214.3ml and 31.2 ± 18.6, respectively. Multidetector computed tomographic angiography (MDCTA) revealed pulmonary artery injury (11.5%), necrosis/cavitation (25.8%), and pulmonary artery embolization was performed in 15.3% of cases. Technical success was 92%. SAPS 2 (p = 0.01), massive hemoptysis (p < 0.001), Terlipressin use (p = 0.01), necrosis/cavitation (p = 0.01), and pulmonary artery injury on MDCTA (p < 0.001) were associated with recurrent hemoptysis. Independent predictors on multivariate analysis were massive hemoptysis (p = 0.016) and pulmonary artery injury on MDCTA (p = 0.001). CONCLUSION: In patients with lung cancer and life-threatening hemoptysis treated by BAE, massive hemoptysis and pulmonary artery injury identified on MDCTA are independent predictors of recurrent hemoptysis.

Association between lactate dehydrogenase and ventilator-associated pneumonia risk: an analysis of the MIMIC database 2001-2019.

BACKGROUND: Serum lactate dehydrogenase (LDH) is a nonspecific inflammatory biomarker and has been reported to be associated with pneumonia prognosis. This study aimed to evaluate the relationship between LDH levels and ventilator-associated pneumonia (VAP) risk in intensive care unit (ICU) patients. METHODS: This retrospective cohort study used data from the Multiparameter Intelligent Monitoring in Intensive Care database from 2001 to 2019. ICU patients aged ≥ 18 years and receiving mechanical ventilation were included. LDH levels were analyzed as continuous and categorical variables (< 210, 210-279, 279-390, > 390 IU/L), respectively. Restricted cubic spline (RCS) curves and quartiles were used to categorize LDH levels. Logistic regression and linear regression were utilized to assess the relationship of LDH levels with VAP risk and duration of mechanical ventilation, respectively. RESULTS: A total of 9,164 patients were enrolled, of which 646 (7.05%) patients developed VAP. High levels of LDH increased the risk of VAP [odds ratio (OR) = 1.15, 95% confidence interval (CI): 1.06-1.24] and LDH levels were positively correlated with the duration of mechanical ventilation [ß = 4.49, 95%CI: (3.42, 5.56)]. Moreover, patients with LDH levels of 279-390 IU/L (OR = 1.38, 95%CI: 1.08-1.76) and > 390 IU/L (OR = 1.50, 95%CI: 1.18-1.90) had a higher risk of VAP than patients with LDH levels < 210 IU/L. Patients with LDH levels of 279-390 IU/L [ß = 3.84, 95%CI: (0.86, 6.82)] and > 390 IU/L [ß = 11.22, 95%CI: (8.21, 14.22)] (vs. <210 IU/L) had a longer duration of mechanical ventilation. CONCLUSION: Elevated serum LDH levels were related to a higher risk of VAP and longer duration of mechanical ventilation and may be useful for monitoring VAP risk.

Use of High-Flow Nasal Cannulas in Saudi's Neonatal Level III Intensive Care Units: A Nationwide Questionnaire Study.

Objective. To describe heated humidified high-flow nasal cannulas (HHHFNC) utilization in level III neonatal intensive care units (NICUs) in Saudi Arabia. Methods. A prospective cross-sectional study using an electronic web-based questionnaire. The survey targeted level III NICUs hospitals using HHHFNCs, covering HHHFNC availability, protocols, patient characteristics, and indications. It also collected opinions on the benefits of HHHFNCs compared to nasal continuous positive airway pressure (nCPAP). Results. Out of 47 government-level III neonatal intensive care units, 35 (74%) responded to the survey. Among the included units, 46% had guidelines for HHHFNC use. Additionally, 51% reported using HHHFNC in infants of all gestational ages. The primary indication for HHHFNC use was weaning off nCPAP (34%), with 60% of the respondents noting its advantages for kangaroo care and breastfeeding. Conclusion. HHHFNC are increasingly prevalent in NICUs in Saudi Arabia. However, there remain no clear policies or guidelines regarding their use in preterm infants.

Clinical Characteristics and Outcomes of an Intensive Maternal Care Unit in a Tertiary Hospital in the Philippines.

Objectives: This is the first study that provides an overview of the characteristics of a specialized Intensive Maternal Care Unit (IMU) that caters to obstetric-related conditions in the Philippines. This study aims to describe the different kinds of cases admitted into this facility, the different medical and surgical interventions employed, length of hospital stay, and maternal and fetal outcomes of these patients. Methods: This is a cross-sectional descriptive study based on a chart review of medical records and admission charts of patients admitted to the Intensive Maternal Unit of a tertiary hospital in Manila from January 2017 to December 2019. Results: There were a total of 17,185 obstetric admissions from 2017-2019. There were a total of 841 admissions (4%) into the Intensive Maternal Unit, with an average of 280 admissions per year. The average length of Intensive Maternal Unit stay was 10.46 days and the average length of hospital stay was 12.98 days. Maternal outcomes were the following: 56.89% were discharged undelivered while 38.92% delivered on their initial admission. The maternal mortality rate was 2.39% among those admitted to the IMU. Among those discharged undelivered, 43% were re-admitted, 6% were admitted twice, and 4% were admitted three times. The most common reason for admission was pregnancy-related hypertensive diseases (34%). Blood transfusion (2.4%), the use of ventilator support (0.6%), and the use of inotropic drugs (0.6%) were the major medical interventions. Cesarean section was the most common surgical intervention, seen in 54.49% of patients. Most neonates were admitted to the neonatal ICU (23.95%), at an average pediatric age of 33 weeks, with an average length of stay in the Neonatal ICU of 12.33 days. Conclusion: Pregnant women are a special group of patients with different needs compared to the general patient population. Pregnancy-associated hypertensive disease is the most common cause of admission to the IMU and hospitals should be able to cater to these patients who will present in their institutions, as this may lead to poor maternal and neonatal outcomes. An Intensive Care Unit dedicated to complicated obstetric care in institutions is recommended to cater to high-risk pregnancies.

Artificial Intelligence in the Intensive Care Unit: Current Evidence on an Inevitable Future Tool.

Artificial intelligence (AI) is a technique that attempts to replicate human intelligence, analytical behavior, and decision-making ability. This includes machine learning, which involves the use of algorithms and statistical techniques to enhance the computer's ability to make decisions more accurately. Due to AI's ability to analyze, comprehend, and interpret considerable volumes of data, it has been increasingly used in the field of healthcare. In critical care medicine, where most of the patient load requires timely interventions due to the perilous nature of the condition, AI's ability to monitor, analyze, and predict unfavorable outcomes is an invaluable asset. It can significantly improve timely interventions and prevent unfavorable outcomes, which, otherwise, is not always achievable owing to the constrained human ability to multitask with optimum efficiency. AI has been implicated in intensive care units over the past many years. In addition to its advantageous applications, this article discusses its disadvantages, prospects, and the changes needed to train future critical care professionals.
