Effects of strengthening prospective nursing practice on sleep quality,anxiety,and depression of awake patients in intensive care unit

BACKGROUND The intensive care unit(ICU)is a specialized hospital department.Awake patients in the ICU frequently encounter adverse psychological states,such as anxiety and fear,often accompanied by poor sleep quality.This situation has garnered significant attention within the medical community.AIM To investigate the impact of prospective nursing intervention strategies on the sleep quality and negative emotional state of conscious ICU patients.METHODS One hundred and twenty ICU awake patients admitted to our hospital were selected and randomly divided into control(n=60)and observation(n=60)groups.Patients in the control group were cared for using the conventional nursing model,while patients in the observation group were cared for using the prospective nursing model.Sleep improvement was assessed using the International Standardized Sleep Efficiency Formula and Pittsburgh Sleep Quality Index(PSQI).The PSQI,Generalized Anxiety Disorder 7-item(GAD-7)scale,Self-Depression Scale(SDS),and satisfaction before and after treatment were used to assess the negative emotional states of patients under the two care models.RESULTS Patient satisfaction in the observation group was significantly higher than in the control group.The GAD-7 and SDS scores in the observation group were significantly lower than those in the control group,and the total effective rate of sleep improvement in the observation group was significantly higher than in the control group.After treatment,the PSQI scores of the two groups significantly decreased(P<0.05).The decrease in the observation group was more significan than that in the control group,and the difference between the two groups was statistically significant.CONCLUSION Prospective nursing interventions can improve sleep quality and psychological levels and significantly affect conscious patients in the ICU,which is worthy of clinical application.

Risk factors for post-traumatic stress disorder among young and middle-aged cancer patients in the intensive care unit:A casecontrol study

BACKGROUND Young and middle-aged cancer patients in intensive care unit(ICU)often suffer from stress and pressure,causing huge physical and mental damage.Currently,there is few research on post-traumatic stress disorder(PTSD)among young and middle-aged cancer patients in ICU in China,and the psychological status of patients who have experienced both cancer development and ICU stay is still unclear.AIM To explore the risk factors for PTSD in young and middle-aged patients with cancer in ICU.METHODS Using convenient sampling method,we enrolled 150 young and middle-aged patients with cancer who were admitted to the ICU of our center during the period from July to December 2020.The general data of the patients and PTSDrelated indicators were collected.The Impact of Event Scale-Revised(IES-R)was used for assessing PTSD one month after the discharge from the ICU.Binary Logistic regression analysis was performed to assess the independent risk factors for PTSD in these patients.RESULTS Among these 150 patients,32(21.33%)were found to be with PTSD.Binary Logistic regression analysis revealed that factors significantly associated with PTSD among young and middle-aged patients with cancer in ICU included monthly income(OR=0.24,P=0.02),planned transfers(OR=0.208,P=0.019),and Acute Physiology and Chronic Health Evaluation(APACHE II)score(OR=1.171,P=0.003).CONCLUSION The low monthly income,unplanned transfers,and increased APACHE II score are the risk factors for PTSD in young and middle-aged patients with cancer in ICU.

Antibiotic sensitivity pattern of bacterial pathogens in the intensive care unit of Fatmawati Hospital,Indonesia

Objective:To evaluate the sensitivity pattern of bacterial pathogens in the intensive care unit(ICU) of a tertiary care of Falmawati Hospital Jakarta Indonesia.Methods:A cross sectional retrospective study of bacterial pathogen was carried out on a total of 722 patients that were admitted to the ICU of Fatmawati Hospital Jakarta Indonesia during January 2009 to March 2010. All bacteria were identified by standard microbiologic methods,and(heir antibiotic susceptibility testing was performed using disk diffusion method.Results:Specimens were collected from 385 patients who were given antimicrobial treatment,of which 249(64.68%) were cultured positive and 136(35.32%) were negative.The most predominant isolate was Pseudomonas aeruginosa(P.aeruginosa)(26.5%) followed by Klebsiella pneumoniae(K.pneumoniae)(15.3%) and Staphylococcus epidermidis(14.9%).P.aeruginosa isolates showed high rate of resistance to cephalexin(95.3%),cefotaxime(64.1%),and ceftriaxone(60.9%).Amikacin was the most effective(84.4%) antibiotic against P.aeruginosa followed by imipenem(81.2%),and meropenem(75.0%).K.pneumoniae showed resistance to cephalexin(86.5%),ceftriaxone(75.7%),ceftazidime(73.0%),cefpirome(73.0%) and cefotaxime(67.9%),respectively.Conclusions:Most bacteria isolated from ICU of Fatmawati Hospital Jakarta Indonesia were resistant to the third generation of cephalosporins,and quinolone antibiotics.Regular surveillance of antibiotic susceptibility pallerns is very important for setting orders to guide the clinician in choosing empirical or directed therapy of infected patients.

Clinical and Microbiological Characteristics of Patients with Complicated Intra-abdominal Infections in Intensive Care Unit

In order to investigate the clinical and microbiological characteristics of patients with complicated intra-abdominal infections(cIAIs)in intensive care unit(ICU),the clinical data of 612 cIAIs patients from January 2016 to December 2018 were retrospectively collected.Clinical characteristics,distribution of pathogens and drug resistance were statistically analyzed.It was found that patients with community-acquired intra-abdominal infections(CA-IAIs)made up a majority of cIAIs patients.The positive rate of abdominal drainage fluid culture was 55.56%.Gramnegative bacteria accounted for the majority,the most commonly isolated bacteria of which were Escherichia coli(20.96%),Klebsiella pneumoniae(10.20%)and Pseudomonas aeruginosa(5.57%).The most commonly isolated gram-positive bacteria were Enterococcus(16.88%)and Methicillinresistant staphylococcus aureus(MRSA,3.90%).Enterobacter isolates showed high resistance rate to most cephalosporins and low resistance rate to piperacillin/tazobactam and carbapenems.Extended spectrum beta-lactamase(ESBL)screen positive isolates from CA-IAIs patients showed an increasing trend in past three years.Enterococcus and MRSA showed high resistance rate to clindamycin,quinolone,erythromycin and tetracycline,while they showed high sensitivity rate to linezolid,tegacycline,teicoplanin and vancomycin.Our results indicate that isolated bacteria from abdominal drainage fluid show high resistance rates to commonly used antibiotics in ICU patients with cIAIs.The curative effects on diseases should be monitored continuously when antibiotics are used.Meanwhile,we should always keep eyes on drug-resistant bacteria,especially when the treatment efficacy is not good.

Management of procedural pain in the intensive care unit

Pain is a common experience for inpatients,and intensive care unit(ICU)patients undergo more pain than other departmental patients,with an incidence of 50%at rest and up to 80%during common care procedures.At present,the management of persistent pain in ICU patients has attracted considerable attention,and there are many related clinical studies and guidelines.However,the management of transient pain caused by certain ICU procedures has not received sufficient attention.We reviewed the different management strategies for procedural pain in the ICU and reached a conclusion.Pain management is a process of continuous quality improvement that requires multidisciplinary team cooperation,painrelated training of all relevant personnel,effective relief of all kinds of pain,and improvement of patients'quality of life.In clinical work,which involves complex and diverse patients,we should pay attention to the following points for procedural pain:(1)Consider not only the patient's persistent pain but also his or her procedural pain;(2)Conduct multimodal pain management;(3)Provide combined sedation on the basis of pain management;and(4)Perform individualized pain management.Until now,the pain management of procedural pain in the ICU has not attracted extensive attention.Therefore,we expect additional studies to solve the existing problems of procedural pain management in the ICU.

Evaluation of progressive early rehabilitation training mode in intensive care unit patients with mechanical ventilation

BACKGROUND Mechanical ventilation is a common resuscitation method in the intensive care unit(ICU).Unfortunately,this treatment process prolongs the ICU stay of patients with an increased incidence of delirium,which ultimately affects the prognosis.AIM To evaluate the effect of progressive early rehabilitation training on treatment and prognosis of patients with mechanical ventilation in ICU.METHODS The convenience sampling method selected 190 patients with mechanical ventilation admitted to the Fourth Hospital of Hebei Medical University from March 2020 to March 2021.According to the random number table method,they were divided into the control and intervention groups.The control group received routine nursing and rehabilitation measures,whereas the intervention group received progressive early rehabilitation training.In addition,the incidence and duration of delirium were compared for the two groups along with mechanical ventilation time,ICU hospitalization time,functional independence measure(FIM)score,Barthel index,and the incidence of complications(deep venous thrombosis,pressure sores,and acquired muscle weakness).RESULTS In the intervention group,the incidence of delirium was significantly lower than in the control group(28%vs 52%,P<0.001).In the intervention group,the duration of delirium,mechanical ventilation time,and ICU stay were shorter than in the control group(P<0.001).The FIM and Barthel index scores were significantly higher in the intervention group than the control group(P<0.001).The total incidence of complications in the intervention group was 3.15%,which was lower than 17.89%in the control group(P<0.001).CONCLUSION Progressive early rehabilitation training reduced the incidence of delirium and complications in ICU patients with mechanical ventilation,which improved prognosis and quality of life.

New strategy for distal limb perfusion in veno-arterial extracorporeal membrane oxygenation treatment: application of continuous renal replacement therapy tubing

Extracorporeal membrane oxygenation(ECMO)is a technology that can temporarily take over the functions of the heart and lungs.Acute kidney injury is a common issue in patients receiving ECMO treatment,with reported incidence rates ranging from 70%to 85%.[1]To maintain the balance of fluids and electrolytes in patients,continuous renal replacement therapy(CRRT)is frequently employed.

Identification prognostic features related to sphingolipid metabolism and experimental validation of TRIM47 in hepatocellular carcinoma

Background:The specific impact of sphingolipid metabolism on developing hepatocellular Carcinoma(HCC)remains unclear.This study aims to explore the relationship between sphingolipid metabolism and HCC prognosis,immune response,and drug sensitivity.Methods:Data were obtained from The Cancer Genome Atlas(TCGA)-Hepatocellular Carcinoma(LIHC)and Gene Expression Omnibus(GEO,GSE14520 datasets).47 sphingolipid metabolism genes were obtained from the Kyoto Encyclopedia of Genes and Genomes(KEGG)database.After classifying HCC samples using the Non-negative Matrix Factorization(NMF)clustering method,differentially expressed genes were screened.Then,8 risk genes were obtained by univariate analysis,survival random forest reduction and lasso analysis.The expression of 8 risk genes was verified in vitro.Results:8 risk genes were used to construct the Sphingolipid score model.High-Sphingolipid score predicted poor prognosis of HCC patients.Sphingolipid score was associated with immune checkpoints(IL-1B,TLR4,TGFB1,and IL-10),immune cells(Th2,Treg,MDSC,Neutrophil,Fibroblasts and macrophage),and MAPK Cascade.In the High-Sphingolipid score group,a significantly higher proportion of patients with TP53(p53)mutations was significantly higher(56%).Furthermore,patients with a high-Sphingolipid score were predicted to have a higher sensitivity to chemotherapy drugs.In vitro validation showed that compared with normal liver cells LX-2,TRIM47,and S100A9 significantly increased in liver cancer cells Hep G2,MHCC-97H,and Hep3B2.1-7,while SLC1A7,LPCAT1,and CFHR4 significantly decreased.Silencing TRIM47 reduced the proliferation and promoted apoptosis.The levels of ceramide synthesis-related indexes(CERS1,CERS6,CERS5,and SPTLC2)increased,and the ACER3 related to catalytic hydrolysis decreased.Conclusion:We constructed a sphingolipid metabolism-related prognostic signature(Sphingolipid score)based on 8 risk genes.TRIM47 may affect the development of liver cancer by regulating the relevant indicators of ceramide synthesis and catalytic hydrolysis.

Primary acinic cell carcinoma of the breast: A case report and review of literature

BACKGROUND In the current World Health Organization classification,acinic cell carcinoma(AcCC)of the breast is considered a rare histological subtype of triple-negative breast cancer.Because of the few reports in the literature,data concerning clinical outcomes are limited.Here,we report a case of AcCC of the breast in a 48-year-old woman.A 48-year-old woman with a mass in her right breast came to our hospital for further diagnosis.Mammography and an ultrasound(US)scan showed a mass in the upper inner side of the right breast.She then underwent surgery to resect the mass in her right breast.Postoperative pathological examination revealed that the tumor had abundant acinar-like structures formed by tumor cells with prominent eosinophilic granules in the cytoplasm,consistent with acinar cell carcinoma.The results of immunohistochemical analysis supported the diagnosis of breast acinar cell carcinoma.Two months later,she underwent breast-conserving surgery and sentinel lymph node biopsy.The pTNM stage was T2N0M0.After surgery,the patient received 30 radiotherapy sessions.The patient was followed up for a period of one year,and no recurrence was found.AcCC of the breast is a rare type of malignant tumor.Because it is usually asym-ptomatic and can be detected by imaging studies,routine breast US or mamm-ograms are important.However,there are no characteristic diagnostic imaging findings or clinical manifestations,so immunohistochemical examination is critical for an accurate diagnosis of AcCC of the breast.

Inhibiting MMP13 Attenuates Deep Vein Thrombosis in a Mouse Model by Reducing the Expression of Pdpn

Objective:Matrix metalloproteinase 13(MMP13)is an extracellular matrix protease that affects the progression of atherosclerotic plaques and arterial thrombi by degrading collagens,modifying protein structures and regulating inflammatory responses,but its role in deep vein thrombosis(DVT)has not been determined.The purpose of this study was to investigate the potential effects of MMP13 and MMP13-related genes on the formation of DVT.Methods:We altered the expression level of MMP13 in vivo and conducted a transcriptome study to examine the expression and relationship between MMP13 and MMP13-related genes in a mouse model of DVT.After screening genes possibly related to MMP13 in DVT mice,the expression levels of candidate genes in human umbilical vein endothelial cells(HUVECs)and the venous wall were evaluated.The effect of MMP13 on platelet aggregation in HUVECs was investigated in vitro.Results:Among the differentially expressed genes,interleukin 1 beta,podoplanin(Pdpn),and factor VIII von Willebrand factor(F8VWF)were selected for analysis in mice.When MMP13 was inhibited,the expression level of PDPN decreased significantly in vitro.In HUVECs,overexpression of MMP13 led to an increase in the expression level of PDPN and induced platelet aggregation,while transfection of PDPN-siRNA weakened the ability of MMP13 to increase platelet aggregation.Conclusions:Inhibiting the expression of MMP13 could reduce the burden of DVT in mice.The mechanism involves downregulating the expression of Pdpn through MMP13,which could provide a novel gene target for DVT diagnosis and treatment.

Impact of next-generation sequencing on antimicrobial treatment in immunocompromised adults with suspected infections

BACKGROUND:Prompt pathogen identification can have a substantial impact on the optimization of antimicrobial treatment.The objective of the study was to assess the diagnostic value of next-generation sequencing(NGS)for identifying pathogen and its clinical impact on antimicrobial intervention in immunocompromised patients with suspected infections.METHODS:This was a retrospective study.Between January and August 2020,47 adult immunocompromised patients underwent NGS testing under the following clinical conditions:1)prolonged fever and negative conventional cultures;2)new-onset fever despite empiric antimicrobial treatment;and 3)afebrile with suspected infections on imaging.Clinical data,including conventional microbial test results and antimicrobial treatment before and after NGS,were collected.Data were analyzed according to documented changes in antimicrobial treatment(escalated,no change,or deescalated)after the NGS results.RESULTS:The median time from hospitalization to NGS sampling was 19 d.Clinically relevant pathogens were detected via NGS in 61.7% of patients(29/47),more than half of whom suffered from fungemia(n=17),resulting in an antimicrobial escalation in 53.2% of patients(25/47)and antimicrobial de-escalation in 0.2% of patients(1/47).Antimicrobial changes were mostly due to the identification of fastidious organisms such as Legionella,Pneumocystis jirovecii,and Candida.In the remaining three cases,NGS detected clinically relevant pathogens also detected by conventional cultures a few days later.The antimicrobial treatment was subsequently adjusted according to the susceptibility test results.Overall,NGS changed antimicrobial management in 55.3%(26/47)of patients,and conventional culture detected clinically relevant pathogens in 14.9% of the patients(7/47).CONCLUSION:With its rapid identification and high sensitivity,NGS could be a promising tool for identifying relevant pathogens and enabling rapid appropriate treatment in immunocompromised patients with suspected infections.

LncRNA LOC103694972 promotes fibrosis of NRK-49F cells by regulating STAT3-dependent Smad/CTGF pathway via targeting miR-29c-3p

Background:Renalfibrosis is an important process in the development of chronic kidney disease.Understanding the pathogenesis andfinding effective treatments for renalfibrosis is crucial.This study aims to investigate whether a newly discovered long non-coding RNA(lncRNA)called LOC103694972 could be a potential target for treatingfibrosis of NRK-49F cells.Methods:LncRNA Chip was used to identify differentially expressed lncRNAs between TGF-β1-induced NRK-49F cells and normal cells.The dual-luciferase assay confirmed the binding between miR-29c-3p and signal transducer and activator of transcription(STAT3),as well as between miR-29c-3p and lncRNA LOC103694972.Si-LOC103694972 and miR-29c-3p mimic were then transfected into TGF-β1-induced NRK-49F cells.Results:The study found that LOC103694972 was highly expressed in TGF-β1-induced NRK-49F cells.These cells exhibited increased cell length and activity compared to the control group.The expression levels of Collagen I,α-Smooth muscle actin(α-SMA),and tissue inhibitor of metalloproteinase(TIMP-1)were increased,while matrix Metalloproteinase 2(MMP2)and matrix Metalloproteinase 9(MMP9)expression was decreased.However,transfection with si-LOC103694972 and miR-29c-3p mimics restored cell morphology and reduced cell viability.This led to a decrease in the levels of Collagen I,α-SMA,and TIMP-1,as well as an increase in MMP2 and MMP9 expression.Additionally,TGF-β1-induced NRK-49F cells transfected with miR-29c-3p mimics activated the STAT3-Smad3/CTGF pathway.Conclusion:Based on thesefindings,lncRNA LOC103694972 shows promise as a target for treating renalfibrosis.It negatively regulates miR-29c-3p and activates the STAT3-Smad3/CTGF pathway.

Influence of initial check, information exchange, final accuracy check, reaction information nursing on the psychology of elderly with lung cancer

BACKGROUND As one of the fatal diseases with high incidence,lung cancer has seriously endangered public health and safety.Elderly patients usually have poor self-care and are more likely to show a series of psychological problems.AIM To investigate the effectiveness of the initial check,information exchange,final accuracy check,reaction(IIFAR)information care model on the mental health status of elderly patients with lung cancer.METHODS This study is a single-centre study.We randomly recruited 60 elderly patients with lung cancer who attended our hospital from January 2021 to January 2022.These elderly patients with lung cancer were randomly divided into two groups,with the control group taking the conventional propaganda and education and the observation group taking the IIFAR information care model based on the conventional care protocol.The differences in psychological distress,anxiety and depression,life quality,fatigue,and the locus of control in psychology were compared between these two groups,and the causes of psychological distress were analyzed.RESULTS After the intervention,Distress Thermometer,Hospital Anxiety and Depression Scale(HADS)for anxiety and the HADS for depression,Revised Piper’s Fatigue Scale,and Chance Health Locus of Control scores were lower in the observation group compared to the pre-intervention period in the same group and were significantly lower in the observation group compared to those of the control group(P<0.05).After the intervention,Quality of Life Questionnaire Core 30(QLQ-C30),Internal Health Locus of Control,and Powerful Others Health Locus of Control scores were significantly higher in the observation and the control groups compared to the pre-intervention period in their same group,and QLQ-C30 scores were significantly higher in the observation group compared to those of the control group(P<0.05).CONCLUSION The IIFAR information care model can help elderly patients with lung cancer by reducing their anxiety and depression,psychological distress,and fatigue,improving their tendencies on the locus of control in psychology,and enhancing their life qualities.

Incidence and Risk Factors of Sub-syndromal Delirium in Patients after Cardiac Surgery

[Objectives]This study aimed to investigate the incidence and risk factors associated with SSD in patients following cardiac surgery.[Methods]A total of 378 patients who underwent cardiac surgery in Taihe Hospital were recruited and screened.Diagnosis of delirium was made using evaluation methods and DSM-5 criteria.SSD was defined as the presence of one or more core features of delirium without meeting the full diagnostic criteria.Statistical analysis included independent samples t-test for group comparisons and binary logistic regression analysis to identify independent risk factors for SSD after cardiac surgery.[Results]Among the 378 subjects,112(29.63%)had SSD,28(7.41%)had delirium,and the remaining 238 patients(62.96%)did not present with delirium.Univariate analysis revealed that age,APACHE II score,duration of aortic clamping,length of ICU stay,duration of sedation use,and daily sleep time were significant risk factors for the occurrence of SSD(P<0.05).Logistic regression analysis identified age>70 years old,APACHE II score>20 points,length of ICU stay>5 d,and duration of sedation use>24 h as independent risk factors for SSD after cardiac surgery(P<0.05).A functional model was fitted based on the analysis results of the binary logistic regression model,yielding the equation logit P=1.472X_(1)+2.213X_(2)+3.028X_(3)+1.306X_(4).[Conclusions]Comprehensive clinical assessment is crucial for patients undergoing cardiac surgery,and appropriate preventive measures should be taken for patients with identified risk factors.Close monitoring of the patient s consciousness should be implemented postoperatively,and timely interventions should be conducted.Further research should focus on model validation and optimization.

Association of donor hepatectomy time with liver transplantation outcomes: A multicenter retrospective study

BACKGROUND Prolonged donor hepatectomy time may be implicated in early and late complications of liver transplantation.AIM To evaluate the impact of donor hepatectomy time on outcomes of liver transplant recipients,mainly early allograft dysfunction.METHODS This multicenter retrospective study included brain-dead donors and adult liver graft recipients.Donor-recipient matching was obtained through a crossover list.Clinical and laboratory data were recorded for both donors and recipients.Donor hepatectomy,cold ischemia,and warm ischemia times were recorded.Primary outcome was early allograft dysfunction.Secondary outcomes included need for retransplantation,length of intensive care unit and hospital stay,and patient and graft survival at 12 months.RESULTS From January 2019 to December 2021,a total of 243 patients underwent a liver transplant from a brain-dead donor.Of these,57(25%)developed early allograft dysfunction.The median donor hepatectomy time was 29(23–40)min.Patients with early allograft dysfunction had a median hepatectomy time of 25(22–38)min,whereas those without it had a median time of 30(24–40)min(P=0.126).CONCLUSION Donor hepatectomy time was not associated with early allograft dysfunction,graft survival,or patient survival following liver transplantation.

Preventable readmission to intensive care unit in critically ill cancer patients

BACKGROUND:Readmission to intensive care unit(ICU)after discharge to ward has been reported to be associated with increased hospital mortality and longer length of stay(LOS).The objective of this study was to investigate whether ICU readmission are preventable in critically ill cancer patients.METHODS:Data of patients who readmitted to intensive care unit(ICU)at National Cancer Center/Cancer Hospital of Chinese Academy of Medical Sciences(CAMS)and Peking Union Medical College(PUMC)between January 2013 and November 2016 were retrospectively collected and reviewed.RESULTS:A total of 39 patients were included in the final analysis,and the overall readmission rate between 2013 and 2016 was 1.32%(39/2,961).Of 39 patients,32(82.1%)patients were judged as unpreventable and 7(17.9%)patients were preventable.There were no significant differences in duration of mechanical ventilation,ICU LOS,hospital LOS,ICU mortality and in-hospital mortality between patients who were unpreventable and preventable.For 24 early readmission patients,7(29.2%)patients were preventable and 17(70.8%)patients were unpreventable.Patients who were late readmission were all unpreventable.There was a trend that patients who were preventable had longer 1-year survival compared with patients who were unpreventable(100%vs.66.8%,log rank=1.668,P=0.196).CONCLUSION:Most readmission patients were unpreventable,and all preventable readmissions occurred in early period after discharge to ward.There were no significant differences in short term outcomes and 1-year survival in critically ill cancer patients whose readmissions were preventable or not.

Improving pressure ulcer care in intensive care units:Evaluating the impact of bundled care and silver nanoparticle dressings

BACKGROUND Pressure ulcer(PU)are prevalent among critically ill trauma patients,posing substantial risks.Bundled care strategies and silver nanoparticle dressings offer potential solutions,yet their combined effectiveness and impact on patient satisfaction remain insufficiently investigated.AIM To assess the impact of bundled care along with silver nanoparticle dressing on PUs management and family satisfaction in critically ill trauma patients.METHODS A total of 98 critically ill trauma patients with PUs in intensive care unit(ICU)were included in this study.Patients were randomly assigned to either the control group(conventional care with silver nanoparticle dressing,n=49)or the intervention group(bundled care with silver nanoparticle dressing,n=49).The PU Scale for Healing(PUSH)tool was used to monitor changes in status of pressure injuries over time.Assessments were conducted at various time points:Baseline(day 0)and subsequent assessments on day 3,day 6,day 9,and day 12.Family satisfaction was assessed using the Family Satisfaction ICU 24 ques-tionnaire.RESULTS No significant differences in baseline characteristics were observed between the two groups.In the intervention group,there were significant reductions in total PUSH scores over the assessment period.Specifically,surface area,exudate,and tissue type parameters all showed significant improvements compared to the control group.Family satisfaction with care and decision-making was notably higher in the intervention group.Overall family satisfaction was significantly better in the intervention group.CONCLUSION Bundled care in combination with silver nanoparticle dressings effectively alleviated PUs and enhances family satisfaction in critically ill trauma patients.This approach holds promise for improving PUs management in the ICU,benefiting both patients and their families.

A Nomogram Model for Prediction of Mortality Risk of Patients with Dangerous Upper Gastrointestinal Bleeding:A Two-center Retrospective Study

Objective:This study aimed to establish a nomogram model to predict the mortality risk of patients with dangerous upper gastrointestinal bleeding(DUGIB),and identify high-risk patients who require emergent therapy.Methods:From January 2020 to April 2022,the clinical data of 256 DUGIB patients who received treatments in the intensive care unit(ICU)were retrospectively collected from Renmin Hospital of Wuhan University(n=179)and the Eastern Campus of Renmin Hospital of Wuhan University(n=77).The 179 patients were treated as the training cohort,and 77 patients as the validation cohort.Logistic regression analysis was used to calculate the independent risk factors,and R packages were used to construct the nomogram model.The prediction accuracy and identification ability were evaluated by the receiver operating characteristic(ROC)curve,C index and calibration curve.The nomogram model was also simultaneously externally validated.Decision curve analysis(DCA)was then used to demonstrate the clinical value of the model.Results:Logistic regression analysis showed that hematemesis,urea nitrogen level,emergency endoscopy,AIMS65,Glasgow Blatchford score and Rockall score were all independent risk factors for DUGIB.The ROC curve analysis indicated the area under curve(AUC)of the training cohort was 0.980(95%CI:0.962-0.997),while the AUC of the validation cohort was 0.790(95%CI:0.685-0.895).The calibration curves were tested for Hosmer-Lemeshow goodness of fit for both training and validation cohorts(P=0.778,P=0.516).Conclusion:The developed nomogram is an effective tool for risk stratification,early identification and intervention for DUGIB patients.

Symptomatic and optimal supportive care of critical COVID-19:A case report and literature review

BACKGROUND Coronavirus disease 2019(COVID-19)severity is classified as asymptomatic,mild,moderate,severe,and critical.Mild cases account for a large percentage of cases in the epidemic and typically exhibit a favorable prognosis.However,a 49%-67%mortality is noted in critical cases.No COVID-19-specific drug has been reported to date,and symptomatic and optimal supportive care,including oxygenation,anti-coinfection treatments,and ventilation,represent the mainstay of treatment for this disease,especially in critical patients.CASE SUMMARY In the above-mentioned context,we share our experience with the treatment of one critical COVID-19 case and review the relevant literature.CONCLUSION Timely tracheal intubation,reasonable mechanical ventilation support,appropriate anti-infection treatment,and early anticoagulation and immunity support are key factors in the successful treatment of this case.
