Percepción de los familiares de pacientes críticos en relación a la comunicación que le brinda el profesional de enfermería de la unidad de cuidados intensivos / Perception of the relatives of critically ill patients in relation to the communication pro-vided by the nursing professional of the intensive care unit

Introducción: cuando un individuo es hospitalizado en UCI para control y monitorización permanente de su salud, su cuidado está orientado específicamente a la asistencia plena de médicos y personal de enfermería. La complejidad de estos cuidados genera una crisis situacional y emocional en la familia que causa ansiedad, estrés, miedo y duda. La forma en la que el enfermero intervenga con el familiar en situaciones críticas es lo que va a determinar la percepción de los mismos hacia el cuidado de enfermería, en tanto la comunicación y el apoyo emocional forma parte de la competencia profesional y contribuye al cuidado holístico del paciente y familia. Objetivo: Determinar la percepción de los familiares de pacientes, respecto a la comunicación que le brinda el profesional de enfermería en la unidad de cuidados críticos. Materiales y método: Se realizó un estudio de tipo cuantitativo, descriptivo y de corte transversal. La muestra estuvo constituida por 40 familiares adultos responsables del paciente hospitalizado en la unidad de terapia intensiva, durante los meses Junio - septiembre del 2023. El instrumento de recolección de información fue un cuestionario de "Percepción de los familiares de los Pacientes Críticos, respecto a la intervención de Enfermería durante su Crisis Situacional"; el mismo fue utilizado y validado por la autora Franco Canales Rosa aplicado en el Hospital Nacional Edgardo Rebagliati, Abril de 2003. Resultados:Los resultados muestran que la percepción global de los familiares, es favorable, respecto a la comunicación verbal, comunicación no verbal y el apoyo emocional[AU]

Introduction: health is the condition in which every living being enjoys absolute well-being both physically and mentally and socially, when it is affected either by a pathology or by general accidents; Given the physical condition of the individual, he or she is often hospitalized in the ICU for permanent control and monitoring. Your care is specifically oriented towards the full assistance of Doctors and Nurses. The complexity of this care generates a situational and emotional crisis in the immediate family that causes anxiety, stress, fear and doubt. The way in which the nurse supports the family member in critical or distressing situations is what will determine the perception of the family members towards the nurses, since communication and emotional support are part of the professional competence and contribute to the holistic care of the patient. patient and family. It is a care that is reflected in the feeling that the nurses have that when they do it, the families are very grateful and that, without a doubt, it is their job. Objective: Determine the perception of the patient's relatives regarding the communication provided by the nursing professional in the critical care unit of a private institution. Materials and Methods: A quantitative, descriptive and cross-sectional study was carried out. The sample was made up of 40 adult relatives responsible for the patient hospitalized in the Adult intensive care unit, during the months of June - September 2023. The information collection instrument was a questionnaire on "Perception of relatives of Critical Patients, regarding to Nursing intervention during their Situational Crisis"; It was used and validated by the author Franco Canales Rosa applied at the Edgardo Rebagliati National Hospital, April 2003. Results:The results show that the overall perception of family members is favorable, regarding verbal communication, non-verbal communication and emotional support[AU]

Introdução: saúde é a condição em que todo ser vivo goza de absoluto bem-estar tanto físico quanto mental e social, quando é acometido por alguma patologia ou por acidentes gerais; Dada a condição física do indivíduo, muitas vezes ele é internado em UTI para controle e monitoramento permanente.

The effect of tranexamic acid on blood transfusion in lower gastrointestinal bleeding-A double blind prospective randomised controlled trial.

PURPOSE: Acute gastrointestinal bleeding is a common emergency. Tranexamic acid (TXA) reduces clot breakdown by inhibiting the action of plasmin and has been shown to reduce the need for blood transfusion in trauma, surgical procedures, and upper gastrointestinal bleeding. This study examined the efficiency of intravenous TXA in patients with acute lower gastrointestinal bleeding. METHODS: Eighty-one patients aged >18 years with lower GI hemorrhage, presenting as active rectal bleeding and anemia (hemoglobin lower than 11 g/dL or a decrease of 2 gr/dl from the patient's base level), were enrolled in this single center, double blind prospective research. Patients were randomly assigned to receive intravenous TXA or placebo from admission until colonoscopy took place. The need for transfusion of packed red blood cells (PRBC) and number of units was recorded and compared between the two groups. RESULTS: Eighty-one patients were randomized in this study, thirty-nine in the TXA arm, and forty-two in the placebo arm. Patient characteristics did not differ between the groups. Forty-three out of the 81 patients received blood transfusion; twenty-two were on the placebo arm and twenty-one on the TXA arm (p = 0.89). Twenty-nine patients required 2 or more units, 14 in the TXA arm and 15 in the placebo arm (p = 0.98). CONCLUSIONS: Intravenous TXA has no significant effect on blood requirement in patients with lower GI bleeding. There was no difference in the consumption of PRBC units among the patients in the placebo and TXA groups. It seems that tranexamic acid has no significant effect on transfusion of PRBC units in lower GI bleeding.

Spanish Translation and Cultural Adaptation of the Intensive Care Unit Delirium Playbook.

Background: A lack of high-quality provider education hinders the delivery of standard-of-care delirium detection and prevention practices in the intensive care unit (ICU). To fill this gap, we developed and validated an e-learning ICU Delirium Playbook consisting of eight videos and a 44-question knowledge assessment quiz. Given the increasing Spanish-speaking population worldwide, we translated and cross-culturally adapted the playbook from English into Spanish. Objective: To translate and culturally adapt the ICU Delirium Playbook into Spanish, the second most common native language worldwide. Methods: The translation and cross-cultural adaptation process included double forward and back translations and harmonization by a 14-person interdisciplinary team of ICU nurses and physicians, delirium experts, methodologists, medical interpreters, and bilingual professionals representing many Spanish-speaking global regions. After a preeducation quiz, a nurse focus group completed the playbook videos and posteducation quiz, followed by a semistructured interview. Results: The ICU Delirium Playbook: Spanish Version maintained conceptual equivalence to the English version. Focus group participants posted mean (standard deviation) pre- and post-playbook scores of 63% (10%) and 78% (12%), with a 15% (11%) pre-post improvement (P = 0.01). Participants reported improved perceived competency in performing the Confusion Assessment Method for the ICU and provided positive feedback regarding the playbook. Conclusion: After translation and cultural adaptation, the ICU Delirium Playbook: Spanish Version yielded significant knowledge assessment improvements and positive feedback. The Spanish playbook is now available for public dissemination.

Early determination of potential critical quality attributes of therapeutic antibodies in developability studies through surface plasmon resonance-based relative binding activity assessment.

Precise measurement of the binding activity changes of therapeutic antibodies is important to determine the potential critical quality attributes (CQAs) in developability assessment at the early stage of antibody development. Here, we report a surface plasmon resonance (SPR)-based relative binding activity method, which incorporates both binding affinity and binding response and allows us to determine relative binding activity of antibodies with high accuracy and precision. We applied the SPR-based relative binding activity method in multiple forced degradation studies of antibody developability assessment. The current developability assessment strategy provided comprehensive, precise characterization of antibody binding activity in the stability studies, enabling us to perform correlation analysis and establish the structure-function relationship between relative binding activity and quality attributes. The impact of a given quality attribute on binding activity could be confidently determined without isolating antibody variants. We identified several potential CQAs, including Asp isomerization, Asn deamidation, and fragmentation. Some potential CQAs affected binding affinity of antibody and resulted in a reduction of binding activity. Certain potential CQAs impaired antibody binding to antigen and led to a loss of binding activity. A few potential CQAs could influence both binding affinity and binding response and cause a substantial decrease in antibody binding activity. Specifically, we identified low abundance Asn33 deamidation in the light chain complementarity-determining region as a potential CQA, in which all the stressed antibody samples showed Asn33 deamidation abundances ranging from 4.2% to 27.5% and a mild binding affinity change from 1.76 nM to 2.16 nM.

Process of Withdrawal of Mechanical Ventilation at End of Life in the ICU: Clinician Perceptions.

BACKGROUND: Nearly one-quarter of all Americans die in the ICU. Many of their deaths are anticipated and occur following the withdrawal of mechanical ventilation (WMV). However, there are few data on which to base best practices for interdisciplinary ICU teams to conduct WMV. RESEARCH QUESTION: What are the perceptions of current WMV practices among ICU clinicians, and what are their opinions of processes that might improve the practice of WMV at end of life in the ICU? STUDY DESIGN AND METHODS: This prospective two-center observational study conducted in Boston, Massachusetts, the Observational Study of the Withdrawal of Mechanical Ventilation (OBSERVE-WMV) was designed to better understand the perspectives of clinicians and experience of patients undergoing WMV. This report focuses on analyses of qualitative data obtained from in-person surveys administered to the ICU clinicians (nurses, respiratory therapists, and physicians) caring for these patients. Surveys assessed a broad range of clinician perspectives on planning, as well as the key processes required for WMV. This analysis used independent open, inductive coding of responses to open-ended questions. Initial codes were reconciled iteratively and then organized and interpreted using a thematic analysis approach. Opinions were assessed on how WMV could be improved for individual patients and the ICU as a whole. RESULTS: Among 456 eligible clinicians, 312 in-person surveys were completed by clinicians caring for 152 patients who underwent WMV. Qualitative analyses identified two main themes characterizing high-quality WMV processes: (1) good communication (eg, mutual understanding of family preferences) between the ICU team and family; and (2) medical management (eg, planning, availability of ICU team) that minimizes patient distress. Team member support was identified as an essential process component in both themes. INTERPRETATION: Clinician perceptions of the appropriateness or success of WMV prioritize the quality of team and family communication and patient symptom management. Both are modifiable targets of interventions aimed at optimizing overall WMV.

Mobile App-Based Mindfulness Intervention for Addressing Psychological Distress Among Survivors of Hospitalization for COVID-19 Infection.

BACKGROUND: Psychological distress symptoms are present and persistent among many patients who survive a critical illness like COVID-19. RESEARCH QUESTION: Could a self-directed mobile app-delivered mindfulness intervention be feasibly and rapidly implemented within a clinical trials network to reduce distress symptoms? STUDY DESIGN AND METHODS: A randomized clinical trial was conducted between January 2021 and May 2022 at 29 US sites and included survivors of hospitalization due to COVID-19-related illness with elevated symptoms of depression at discharge. Participants were randomized to intervention or usual care control. The intervention consisted of four themed weeks of daily audio, video, and text content. All study procedures were virtual. The primary outcome was depression symptoms assessed with the Patient Health Questionnaire 9 at 3 months. Secondary outcomes included anxiety (Generalized Anxiety Disorder 7-item scale), quality of life (EQ-5D), and adherence. We used general linear models to estimate treatment arm differences in outcomes over time. RESULTS: Among 56 randomized participants (mean age ± SD, 51.0 ± 13.2 years; 38 female [67.9%]; 14 Black participants [25%]), 45 (intervention: n = 23 [79%]; control: n = 22 [81%]) were retained at 6 months. There was no difference in mean improvement between intervention and control participants at 3 months in Patient Health Questionnaire 9 (-0.5 vs 0.1), Generalized Anxiety Disorder 7-item scale (-0.3 vs 0.1), or EQ-5D (-0.03 vs 0.02) scores, respectively; 6-month results were similar. Only 15 participants (51.7%) initiated the intervention, whereas the mean number ± SD of the 56 prescribed intervention activities completed was 12.0 ± 15.2. Regulatory approvals delayed trial initiation by nearly a year. INTERPRETATION: Among survivors of COVID-19 hospitalization with elevated psychological distress symptoms, a self-directed mobile app-based mindfulness intervention had poor adherence. Future psychological distress interventions mobilized at broad scale should focus efforts on patient engagement and regulatory simplification to enhance success.

Impact of heat waves on human morbidity and hospital admissions in a city of the western mediterranean area.

PURPOSE: The effect of heat waves on mortality is well known, but current evidence on morbidity is limited. Establishing the consequences of these events in terms of morbidity is important to ensure communities and health systems can adapt to them. METHODS: We thus collected data on total daily emergency hospital admissions, admissions to critical care units, emergency department admissions, and emergency admissions for specific diagnoses to Hospital Universitario de Son Espases from 1 January 2005 to 31 December 2021. A heat wave was defined as a period of ≥ 2 days with a maximum temperature ≥ 35 °C, including a 7 day lag effect (inclusive). We used a quasi-Poisson generalized linear model to estimate relative risks (RRs; 95%CI) for heat wave-related hospital admissions. RESULTS: Results showed statistically significant increases in total emergency admissions (RR 1.06; 95%CI 1 - 1.12), emergency department admissions (RR 1.12; 95%CI 1.07 - 1.18), and admissions for ischemic stroke (RR 1.26; 95%CI 1.02 - 1.54), acute kidney injury (RR 1.67; 95%CI 1.16 - 2.35), and heat stroke (RR 18.73, 95%CI 6.48 - 45.83) during heat waves. CONCLUSION: Heat waves increase hospitalization risk, primarily for thromboembolic and renal diseases and heat strokes.

Nasogastric tube versus postpyloric tube feeding for critical illness: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: Gastric tube feeding and postpyloric tube feeding are two common forms of enteral nutrition in critically ill patients. This study aimed to compare the efficacy and safety of gastric tube feeding with that of postpyloric tube feeding in critically ill patients. METHODS AND STUDY DESIGN: PubMed, Embase, and Cochrane Library were systematically searched for eligible trials from their inception until March 2023. Relative risks (RRs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs) were used to estimate categorical and continuous outcomes using the random-effects model. RESULTS: Sixteen trials involving 1,329 critically ill patients were selected for the final meta-analysis. Overall, we noted that gastric tube feeding showed no significant difference from post-pyloric tube feeding in mortality (p = 0.891), whereas the risk of pneumonia was significantly increased in patients who received gastric tube feeding (RR: 1.45; p = 0.021). Furthermore, we noted that gastric tube feeding was associated with a shorter time required to start feeding (WMD: -11.05; p = 0.007). CONCLUSIONS: This research revealed that initiating feeding through the gastric tube required less time compared to postpyloric tube feeding. However, it was also associated with a heightened risk of pneumonia among critically ill patients.

Scapular morphology does not predict supraspinatus tendon tear propagation following an individualised exercise therapy programme.

Purpose: To determine whether scapular morphology could predict isolated supraspinatus tendon tear propagation after exercise therapy. We hypothesised that a larger critical shoulder angle (CSA) and type III acromial morphology predict a positive change in tear size. Methods: Fifty-nine individuals aged 40-70 years with isolated symptomatic high-grade partial or full-thickness supraspinatus tendon tears were included. Individuals participated in a structured, individualised 12-week exercise therapy programme and underwent ultrasound to measure tear size at baseline and 12 months following therapy. Computed tomography images were segmented to create three-dimensional subject-specific bone models and reviewed by three trained clinicians to measure CSA and to determine acromion morphology based on the Bigliani classification. A binary logistic regression was performed to determine the predictive value of CSA and acromion morphology on tear propagation. Results: The CSA was 30.0 ± 5.4°. Thirty-one individuals (52.5%) had type II acromial morphology, followed by type III and type I morphologies (25.4% and 22.0%, respectively); 81.4% experienced no change in tear size, four (6.8%) individuals experienced tear propagation and seven (11.9%) individuals had a negative change in tear size. No significant difference in tear propagation rates based on CSA or acromion morphology (not significant [NS]) was observed. The model predicted tear size status in 81.4% of cases but only predicted tear propagation 8.3% of the time. Overall, CSA and acromion morphology only predicted 24.3% (R 2 = 0.243) of variance in tear propagation (NS). Conclusions: CSA and acromion morphology were NS predictors of tear propagation of the supraspinatus tendon 12 months following an individualised exercise therapy programme. Level of Evidence: II.

Bickerstaff Brainstem Encephalitis Presenting With Negative Anti-GM1 and Anti-GQ1B Antibodies.

A woman in her 60s initially presented with rapid-onset left-sided hemiparesis with later development of slurred speech and left-sided facial droop. Despite ruling out common causes, her condition rapidly progressed with the development of bilateral proximal weakness, ophthalmoplegia, ataxia, and pyramidal signs eventually leading to a cardiorespiratory arrest. Extensive investigations, including computerised tomography (CT), magnetic resonance imaging (MRI), and lumbar puncture (LP), were negative for infectious or vascular aetiologies. Nerve conduction studies (NCS) revealed severe peripheral nerve damage, and despite a provisional diagnosis of Guillain-Barré Syndrome (GBS), the clinical picture aligned more with Bickerstaff Brainstem Encephalitis (BBE) given the central nervous system (CNS) involvement, despite negative anti-GM1 and anti-GQ1b autoantibodies. Treatment involved ventilatory support, immunoglobulins, and steroids. This case report describes a rare and challenging presentation of BBE and reminds clinicians to have a systematic approach to a patient presenting with rapid onset neurological symptoms and that BBE is a clinical diagnosis.

Fluid Responsiveness and Management in Obstetrics using Point-of-Care Ultrasound.

Fluid management in obstetric care is crucial due to the complex physiological conditions of pregnancy, which complicate clinical manifestations and fluid balance management. This expert review examines the use of point-of-care ultrasound (POCUS) to evaluate and monitor the response to fluid therapy in pregnant patients. Pregnancy induces significant physiological changes, including increased cardiac output and glomerular filtration rate, decreased systemic vascular resistance, and plasma oncotic pressure. Conditions like preeclampsia further complicate fluid management due to decreased intravascular volume and increased capillary permeability. Traditional methods of assessing fluid volume status, such as physical examination and invasive monitoring, are often unreliable or inappropriate. POCUS provides a non-invasive, rapid, and reliable means to assess fluid responsiveness, which is essential in managing fluid therapy in pregnant patients. This review details various POCUS modalities used to measure dynamic changes in fluid status, focusing on the evaluation of the inferior vena cava (IVC), lung ultrasound (Lung US), and the left ventricular outflow tract (LVOT). IVC ultrasound in spontaneously breathing patients determines diameter variability, predicting fluid responsiveness and being feasible even late in pregnancy. Lung ultrasound is critical for detecting early signs of pulmonary edema before clinical symptoms arise and is more accurate than traditional radiography. The LVOT velocity-time integral (VTI) assesses stroke volume response to fluid challenges, providing a quantifiable measure of cardiac function, especially beneficial in critical care settings where rapid and accurate fluid management is essential. The expert review synthesizes current evidence and practice guidelines, suggesting integrating POCUS as a fundamental aspect of fluid management in obstetrics. It calls for ongoing research to enhance techniques and validate their use in broader clinical settings, aiming to improve outcomes for pregnant patients and their babies by preventing complications associated with both under- and over-resuscitation.

Critical Self-reflection on Racism by Hospital Physicians in Large German Cities. A Qualitative Reconstructive Study Using Episodic Interviews.

Racism permeates healthcare institutions and interpersonal interactions, impacting both staff and patients. The role of doctors, given their influential position in the healthcare system, is particularly crucial in this context. Despite this, there is a scarcity of evidence regarding the manifestation of racism among healthcare professionals in Germany. Critical whiteness studies emphasize the importance of white* individuals engaging in critical self-reflection to mitigate racism. This study aimed to explore the attitudes of white* physicians in hospitals in major German cities towards racism and their critical reflection on personal attitudes and actions concerning racism in interactions with staff members and patients. Data was collected through six episodic interviews with physicians, analyzed using the reconstructive qualitative procedure of the documentary method, leading to a sense-genetic typology. The sense-genetic typology revealed three distinct attitudes towards racism: acknowledging, individualistic, and ignoring. Four types emerged concerning the self-reflection of white doctors: self-critical, socially critical, worried, and defensive. The most promising potential for interventions to reduce racism lies within the self-critical and socially critical types, both demonstrating an acknowledging attitude. Conversely, the worrying and defensive types may present challenges in deconstruction. This suggests that interventions aimed at reducing racism should be tailored and implemented with a nuanced approach.

Plasma exchange and intravenous immunoglobulin for the peri-operative management of type 2 heparin-induced thrombocytopaenia in a patient requiring urgent surgery for critical limb ischaemia.

We report the case of a 61-year-old female who developed heparin-induced thrombocytopaenia following treatment of a submassive pulmonary embolism, and who then required an above knee amputation for critical limb ischaemia. Heparin-induced thrombocytopaenia is a rare, immune-mediated complication associated with an in-hospital mortality rate of 10%. It is more common in surgical patients, with patients undergoing orthopaedic surgery more likely to develop it than patients undergoing cardiac surgery, but heparin-dependent immunoglobulin G antibodies are more likely to be formed in the latter. Peri-operative management remains a challenge. Ideally, it is preferable to wait for the platelet count to improve; but in certain cases, surgery cannot be delayed. Heparin-induced thrombocytopaenia is usually managed with direct thrombin inhibitors, such as argatroban and bivalirudin. Newer therapeutic modalities, such as plasmapheresis and intravenous immunoglobulin, as used in this case, can rapidly remove antibodies, but the certainty of evidence is low. Our case adds to the literature regarding the use of these modalities and highlights the multidisciplinary team approach required to manage such complex cases.

From the mathematical model to the patient: The scientific and human aspects of artificial intelligence in gastrointestinal surgery.

Recent medical literature shows that the application of artificial intelligence (AI) models in gastrointestinal pathology is an exponentially growing field, with promising models that show very high performances. Regarding inflammatory bowel disease (IBD), recent reviews demonstrate promising diagnostic and prognostic AI models. However, studies are generally at high risk of bias (especially in AI models that are image-based). The creation of specific AI models that improve diagnostic performance and allow the establishment of a general prognostic forecast in IBD is of great interest, as it may allow the stratification of patients into subgroups and, in turn, allow the creation of different diagnostic and therapeutic protocols for these patients. Regarding surgical models, predictive models of postoperative complications have shown great potential in large-scale studies. In this work, the authors present the development of a predictive algorithm for early post-surgical complications in Crohn's disease based on a Random Forest model with exceptional predictive ability for complications within the cohort. The present work, based on logical and reasoned, clinical, and applicable aspects, lays a solid foundation for future prospective work to further develop post-surgical prognostic tools for IBD. The next step is to develop in a prospective and multicenter way, a collaborative path to optimize this line of research and make it applicable to our patients.

Uses of infrared thermography in acute illness: a systematic review.

Introduction: Infrared thermography (IRT) is a non-contact, non-ionising imaging modality, providing a visual representation of temperature distribution across a surface. Methods: We conducted a systematic search of indexed and grey literature for studies investigating IRT applications involving patients in acute care settings. Studies were categorised and described along themes identified iteratively using narrative synthesis. Quality appraisal of included studies was performed using the Quality Assessment tool for Diagnostic Accuracy Studies. Results: Of 1,060 unique records, 30 studies were included. These were conducted in emergency departments and intensive care units involving adult, paediatric and neonatal patients. IRT was studied for the diagnosis, monitoring or risk stratification of a wide range of individual conditions. IRT was predominantly used to display thermal change associated with localised inflammation or microcirculatory dysfunction. Existing research is largely at an early developmental stage. Discussion: We recommend that high quality diagnostic validation studies are now required for some clinical applications. IRT has the potential to be a valuable tool in the acute care setting and represents an important area for future research particularly when combined with advances in machine learning technology.

Intensive care unit-acquired weakness and mechanical ventilation: A reciprocal relationship.

Intensive care unit-acquired weakness (ICU-AW; ICD-10 Code: G72.81) is a syndrome of generalized weakness described as clinically detectable weakness in critically ill patients with no other credible cause. The risk factors for ICU-AW include hyperglycemia, parenteral nutrition, vasoactive drugs, neuromuscular blocking agents, corticosteroids, sedatives, some antibiotics, immobilization, the disease severity, septicemia and systemic inflammatory response syndrome, multiorgan failure, prolonged mechanical ventilation (MV), high lactate levels, older age, female sex, and pre-existing systemic morbidities. There is a definite association between the duration of ICU stay and MV with ICU-AW. However, the interpretation that these are modifiable risk factors influencing ICU-AW, appears to be flawed, because the relationship between longer ICU stays and MV with ICU-AW is reciprocal and cannot yield clinically meaningful strategies for the prevention of ICU-AW. Prevention strategies must be based on other risk factors. Large multicentric randomized controlled trials as well as meta-analysis of such studies can be a more useful approach towards determining the influence of these risk factors on the occurrence of ICU-AW in different populations.

Unveiling significant risk factors for intensive care unit-acquired weakness: Advancing preventive care.

In this editorial, we discuss an article titled, "Significant risk factors for intensive care unit-acquired weakness: A processing strategy based on repeated machine learning," published in a recent issue of the World Journal of Clinical Cases. Intensive care unit-acquired weakness (ICU-AW) is a debilitating condition that affects critically ill patients, with significant implications for patient outcomes and their quality of life. This study explored the use of artificial intelligence and machine learning techniques to predict ICU-AW occurrence and identify key risk factors. Data from a cohort of 1063 adult intensive care unit (ICU) patients were analyzed, with a particular emphasis on variables such as duration of ICU stay, duration of mechanical ventilation, doses of sedatives and vasopressors, and underlying comorbidities. A multilayer perceptron neural network model was developed, which exhibited a remarkable impressive prediction accuracy of 86.2% on the training set and 85.5% on the test set. The study highlights the importance of early prediction and intervention in mitigating ICU-AW risk and improving patient outcomes.

Facilitating and hindering factors of community nurses' emergency and critical care treatment abilities: A qualitative study.

BACKGROUND: This study adopts a descriptive phenomenological approach to investigate the facilitators and barriers of community nurses' abilities in managing critical and emergency conditions. With the transition of healthcare systems to the community, the evolution of nursing practices, and the attention from policies and practices, community nurses play a crucial role in the management of critical and emergency conditions. However, there is still a lack of comprehensive understanding regarding the factors that promote or hinder their capabilities in this area. AIM: To understand the facilitators and barriers of community nurses in managing critical and emergency conditions, exploring the fundamental reasons and driving forces influencing their treatment capabilities. METHODS: This study utilized the destination sampling method between May 2023 and July 2023. It employed a descriptive phenomenological approach within qualitative research methodologies. Through objective sampling, 17 community nurses from 7 communities in Changning District, Shanghai, were selected as the study subjects. Semi-structured interviews were conducted to gather data, which were subsequently organized and analyzed using Colaizzi's seven-step analysis method, leading to the extraction of final themes. RESULTS: The barrier factors identified from the interviews encompassed three topics: resource allocation, professional factors, and personal literacy. The facilitators comprised three themes: professionalism, management attention, and training and continuing education. We identified that the root causes of the barriers included the lack of practical treatment experience among community nurses, insufficient awareness of self-directed learning, and limited knowledge and technical proficiency. The professional quality of community nurses and management attention serve as motivation for them to enhance their treatment abilities. CONCLUSION: To enhance the capability of community nurses in treating acute and critical patients, it is recommended to bolster training specifically tailored to acute and critical care, raise awareness of first aid practices, and elevate knowledge and skill levels.

25-hydroxyvitamin D and parathyroid hormone in new onset sepsis: A prospective study in critically ill patients.

Hypovitaminosis D is highly prevalent in critically ill patients, and it has been suggested to be a risk factor for infections, sepsis and higher mortality. We sought to investigate whether serum 25-hydroxyvitamin D (25(OH)D) and parathyroid hormone (PTH) in critically ill patients with new onset sepsis are associated with severity and outcome. We prospectively included 50 consecutive critically ill adult cases with new onset sepsis and 50 healthy controls matched for age and sex. PTH and 25(OH)D were determined in serum via electrochemiluminescence immunoassays at inclusion in the study in all cases and controls, and one week after sepsis onset in cases. Patients had reduced 25(OH)D compared to controls at sepsis onset (7.9 ± 3 vs 24.6 ± 6.7 ng/mL, p < 0.001), whilst PTH was similar (median (range): 34.5 (5.7-218.5) vs 44.2 (14.2-98.1) pg/mL, p = 0.35). In patients, 25(OH)D upon enrollment and one week after did not differ significantly (7.9 ± 3 vs 7 ± 4.3 ng/mL, p = 0.19). All patients presented with hypovitaminosis D (25(OH)D < 20 ng/mL), while 40 patients (80 %) had vitamin D deficiency (25(OH)D < 12 ng/mL) at sepsis onset, including all ten (20 %) nonsurvivors, who died within 28 days from sepsis onset. Patients with sepsis (N = 28) and septic shock (N = 22) as well as survivors (N = 40) and nonsurvivors (N = 10) had similar 25(OH)D at enrollment (p > 0.05). 25(OH)D was positively correlated with ionized calcium (r = 0.46, p < 0.001) and negatively with PTH (p < 0.05), while inflammatory biomarkers or the severity scores exhibited no correlation with 25(OH)D. Patients with septic shock and nonsurvivors had lower PTH than patients with sepsis and survivors respectively (42.2 ± 42.9 vs 73.4 ± 61.9 pg/mL, p = 0.04, and 18.3 ± 10.7 vs 69.9 ± 58.8 pg/mL, p = 0.001, respectively). C-reactive protein was negatively associated with PTH (r = -0.44, p = 0.001). In conclusion, vitamin D deficiency was present in 80 % of critically ill patients at sepsis onset, while nonsurvivors exhibited lower PTH than survivors. Additional, larger and multicenter studies are warranted to elucidate the contribution of vitamin D and PTH to the pathogenesis of sepsis and its outcomes.

A Multidisciplinary Curriculum to Standardize Chest Procedures Training for Trainees in General Surgery, Emergency Medicine, and Critical Care.

Introduction: Critical care, emergency medicine, and surgical trainees frequently perform surgical and Seldinger-technique tube thoracostomy, thoracentesis, and thoracic ultrasound. However, approaches to teaching these skills are highly heterogeneous. Over 10 years, we have developed a standardized, multidisciplinary curriculum to teach these procedures. Methods: Emergency medicine residents, surgical residents, and critical care fellows, all in the first year of their respective programs, underwent training in surgical and Seldinger chest tube placement and securement, thoracentesis, and thoracic ultrasound. The curriculum included preworkshop instructional videos and 45-minute in-person practice stations (3.5 hours total). Sessions were co-led by faculty from emergency medicine, thoracic surgery, and pulmonary/critical care who performed real-time formative assessment with standardized procedural steps. Postcourse surveys assessed learners' confidence before versus after the workshop in each procedure, learners' evaluations of faculty by station and specialty, and the workshop overall. Results: One hundred twenty-three trainees completed course evaluations, demonstrating stable and positive responses from learners of different backgrounds taught by a multidisciplinary group of instructors, as well as statistically significant improvement in learner confidence in each procedure. Over time, we have made incremental changes to our curriculum based on feedback from instructors and learners. Discussion: We have developed a unique curriculum designed, revised, and taught by a multidisciplinary faculty over many years to teach a unified approach to the performance of common chest procedures to surgical, emergency medicine, and critical care trainees. Our curriculum can be readily adapted to the needs of institutions that desire a standardized, multidisciplinary approach to thoracic procedural education.
